Iconia Tab W500 Bricked #589

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Make an image of AMD-Brazos 3.2 in a usb drive
2. Boot from it in an Iconia Tab W500
3. =(

So I'm posting this as a warning to everybody out there.

I oficially bricked my W500 today. I was trying to boot from my 4GB FAT usb 
drive with an image of Android AMD-Brazos 3.2. I pressed windows and power to 
boot from USB and the windows button would light up but the screen wouldn't. 
After everything I thought of trying, the screen is still blank and won't even 
display the acer logo.

Can you think of anything? Acer support says it needs to be shipped to their 
facilities for repair.

I have a feeling that somehow I flashed the BIOS. I have the original BIOS 
files from Acer, but I have no idea how to use them.

Any Ideas?

Thanks!

g.gamer0 , many thanks for your help at the moment, we really appreciate ! 
I believe there are a lot of workarounds to try...at the moment you found a way 
to fix the issue if the bios order is changed, we only need to find the way to 
fix the black screen for whom didnt make the change, meant for whom can´t 
easily boot from usb...

seems very interesting what you posted.

Im not able to make those tests yet, but Im searching to help, and probably at 
the end of the week I will be more helpful...

Doing some tests. I completely wiped the hard drive and reset the bios. The 
goal here was to see if it would boot to the USB when seeing no system on the 
hard drive. Boooting left me with a black screen again. no acer logo, no 
nothing. It did not boot to usb on its own. I found that i had to have the usb 
inserted and do the above (power+win button to cursor) then  it did boot to usb 
but only after i did that. Even then the usb boot too aprox 2 - 3 minutes 
before anything came on the screen, this may be due to the fact that i found 
network boot by default is above usb, so i believe it looked there first.
I'll keep testing some things. I hope this is helping someone

Another issue i found, and this maybe so stupid we all overlooked it. I could 
not restore using the win7 usb, or the win7 disks from acer or install using my 
android usb. Even though i could boot from usb after doing the above. After 
going insane, it occured to me that something was preventing the hard drive 
from being default install media. It was the SDcard. I removed the SD card and 
all was well. I don't think this has much affect on most of you but may get 
someone thinking in the right direction.

Has anyone removed the back cover and disconnect the battery for a day or so? I 
think this may bring some of your tablets back. I have done this with desktops 
(cmos battery and no power) and with laptops. Many hold a bad setting in memory 
and any power retains that memory. Removing all power for an amount of time 
will clear that. I have seen many laptops boot right up after doing this, and 
they didn't boot at all before (when i say didn't boot i mean they did nothing 
just powered on on thats it, no screen, no nothing).

G.Gamer0, let me ask you something, to sum up what you did to boot in this 
second method:

  1)  attach USB dock/Keyboard
  2)  insert pendrive with freedos
  3)  press and hold the Start Button (this is the start button on the tablet, not the keyboard) and then press and hold the Power Button. 
  4) wait a few minutes (because network boot is above usb boot) and you will got a screen with freedos 

Are those steps correct ?

If yes, on step 2, did you insert the pendrive on acer or in the dock ? Can be 
any usb ?.
On step 3, did you press power and start or power+win ?

Mwu guys I took in a technical Iconia W500 here in Brazil and the same problem 
and said that the video card he said that the 80% chance of it back if the 
repair is done the same I am in doubt whether to leave the service or leave it 
without doing this repair solutions and look more or take elsewhere to see if 
indeed the problem and video card

 What I find odd and that before taking this other guy told me that the problem was the bios.

GoogleCodeExporter commented 9 years ago
If your install went bad, it wont boot from the hard drive. Your only chance is 
to replace the drive (a quick look at new the same size mSSD is arounf 40-50 
dollars). or get it to boot from usb or CD. To do the second you must do 
exactly as follows to bypass the hard drive.
1) turn the tablet off, not just pressing the button on the front, hold the 
side power button in till the tablet completely shuts down.
2) Wait a bit for the power to discharge (i waited about an hour).
3) insert the tablet into the dock
4) Press and hold the side power button and the start button (win button) on 
the tablet, not the one on keyboard
5) when you see a blinking cursor, quickly let go of the start button and hit 
F2 or F12 on the keyboard (F2 is Bios, F12 is boot menu)

when i blacked mine on purpose, i had no screen. no logo, nothing. By doing 
this i was able to get to bios the first time. The boot menu did not work for 
me. Once to bios i set USB as first boot. This will save you next time. 
Thge second time i blacked it i was not able to get to bios, but by doing this 
was able to boot a flash drive with win8 devoloper. I installed that and the 
tablet worked fine then.
I think all the problems stem from a bad install of andriod. It seems that if 
the tablet can't boot from the hard drive it does nothing. It won't even boot 
from usb unless you do the steps above. This is bad design on Acer's part. 
I find it very hard to believe anyone has a over written bios. For that to 
happen the program had to be specifically written to do that, it doesn't just 
erase and i don't see android doping that. I believe we just need to get it to 
boot from something and all will be fine.
Some of you have an Acer logo. that is good do the steps above and you should 
be able to get booting from USB.
The ones that this doesn't work, pull the hard drive. You should get an error 
on screen. That is good because all is well. Do the steps above and set the 
bios to boot USB and CD first. SHut down and put the hard drive back in. 

Note: Some boots i had to have a usb inserted to get the boot option for it in 
bios. Some boots i did not. I would have one just in  case.
Also after reseting the bios and changing boot order, sometimes it would just 
boot to usb, sometimes not - it would go to hard drive. In that case do the 
step above but do not hit F2 or F12. It will go to USB after you release the 
buttons.

Hope this helps everyone. Make sure you try both ways. and either have your 
restore disks ready or make a win 7 iso on usb (direction in my earlier posts).

From your earlier post I seen you had a no boot device error. That means you do 
have a bios. Another thing you can try is take the drive out and connect it to 
a desktop and format it.

When you want Dual Boot with Android, the safe way is change bootloader to 
Windows. Use EasyBCD to do that and go back to Windows Repair tool and type 
command:
bootrec /fixboot
bootrec /fixmbr.( need unmount SD memory)
How to fix when you see the black screen when Android bootloader is damage? 
Only 1 way is format the SSD hard drive.

GoogleCodeExporter commented 9 years ago
I agree with nnquoct.     Considering the bricking problem some people are 
experiencing, I personally would not mess with installing Android directly to 
the SSD drive.     You should install android on a fat32 SD card or USB drive.  
 If you then want the speed of running android from the SSD,  you should simply 
copy the android directory from the SD/USB to the root of the SSD drive, and 
then use EasyBCD to modify the Windows boot loader to add an option for 
Android.    Details of using this method are provided in the following post - 
just search for EasyBCD.

So from what I have experienced with the teblet there is a fst BIOS boot which 
can be disabled by holding down the windows button and the power button with a 
keyboard connected and hitting F2 in the BIOS under Main dissable Quiet Boot it 
skips the BIOS cheek. now here is the real problem.

Once that is done you know that your Bios is there but you still can't boot 
Thats my problem android won't boot GRUB's messed up or something

I had similar problems with installing 3.2 on my W500.
What I did was installed W8, replacing W7, no issues.
Then I installed A3.2 to the SSD, no format, dual boot. Still ok.
Wanted W7 back, because of WMC. Used recovery CDs & external USB.
Toasts the boot loader it seems, and the 'recovery' partition seemed to cause 
grief because reinstalling Android didn't work.
Used Ubuntu disk to run Ubuntu from the CD and GParted to just delete all 
partitions.
Then used windows 7 recovery, but still issues, no boot.
But installed Android to SSD no format, which installed GRUB and it found the 
windows install.
However, windows scripts messed up GRUB again. Had to reinstall Android again.

In the end I am now back to dual boot, but it no longer has the recovery 
partition, so I need to keep the disks safe :)

Oh, and I had a hell of a time with keeping it booting from the usb dvd, but I 
think that is the dvd drive issue. However F12 will display the boot menu, but 
while you have the fast boot set on in the bios, it is hard to get. To get into 
the bios to turn it off,

Oh I should note, going by memory, just before the last install of Android, 
(Ice Cream, by the way), nothing would boot again.
Another tip, once back working, you may want to edit Menu in the C:\GRUB folder 
with notepad and change default=0 to default=2 if you want windows to be 
default.

I have not tried this, not positive with the recovery disks, but I believe now 
to remove GRUB would need to get the windows boot loader re-installed.

If you are not going to keep Android in dual boot, and the machine is under 
warranty, I think from GPart in ubuntu I would just format the second drive on 
the SSD to NTFS, then use the recovery disks, and if no boot, send it in for 
repairs. Don't delete the first one or they would likely charge you would be my 
guess.

And I did try just deleting the second partition labeled ACER in GParted and 
using the recovery disks, but it did not work. I am not sure if the cause was 
my install of W8 originally or not, so it may work for you.

problem and cant boot from my laptop then today on w500 w8 change fat to fat16 
so the problem from windows 7

Well I did fix mine by using ubuntu live, gpart and delete all partitions, left 
unpartitioned, used recovery disks, install android on NTFS with windows.

The only way I could get to boot to windows 7 doing this was via GRUB though. 
The recovery disks do not seem to put in the windows boot loader. Or that is 
how it acted. I suspect they boot loaded from the recovery partition and the 
recovery disks do not recreate that partition.

The tablet went back yesterday, unrelated, due to defective USB port. 14 day 
return policy is useful, but had to order the replacement online, likely be 
here in the next few days. It will be original install again.

When I get it I will try loading android again on the NTFS partition, but 
without installing Windows 8, and track my steps closer. See what happens.

Oh, abhaba, I found getting into the bios tricky the first time. And once the 
boot loader is messed, I do not remember seeing a cursor.
Did you try pressing power and windows button on the front of the tablet at the 
same time, and once the light comes on, continually pressing up and down the F2 
key? Not waiting for a cursor?
If you do get in, like posted before, turn off the quick boot. Then you should 
be able to use F12 for selecting boot device.

Ok, well Acer uses the first partition as the system partition and the boot on 
it. Why W8 messes things up I believe. 
I attached the files from the partition in case it helps someone.It is NTFS, 
labeled SYSTEM RESERVED and is 111,144,960 bytes. May need to use linux and 
gparted to set things up, like a ubuntu live cd, make sure this first partition 
is system, primary and the second boot primary (and the C drive).
I also don't think installing W8 or Android really bricks things, just messes 
up the way Acer does the boot. And the recovery disks they provide will not 
recreate this partition and expects this partition to be system for boot. Why 
the linux boot loader or another would work.

I also wanted to note that I found to boot from the USB DVD Drive, I had to go 
into the bios every boot and save for the drive to be in the boot menu. Didn't 
have to change anything, although you may want the USB CDROM to be ahead of the 
SSD. Probably a BIOS issue, but workable. I have bios version 1.08

For everyone with this problem, here is another way to solve it, but needs that 
you can open your Iconia.

Someone in a spanish forum that I use, solved this problem using a SSD from 
other Iconia that boots with no problems.  So, that SSD allowed him to enter 
the BIOS without issues, change the booting options, and then installing back 
his own SSD and recovering the system from an external unit (before it reaches 
the SSD).

The result is that his Iconia is back and working perfectly again.

Is another idea, but you need a friend with a working Iconia that lends you his 
disc for a moment.  And both agree to open your Iconias.

Hope this helps too.

Sorry for my english, I'm out of practice.

While I was in the same situation briccato Iconia Tab, and I was really scared.

 My situation was windows 7 on C:, 8 win on D: and installed androidx86 amd_brazor on microSD.
 ...
 ...
 ...
 Until riavviavo Android, everything went smooth ... the first reboot in windows7 still okay, but on reboot for the first time since windows8, when I rebooted, and 'written' error 15 'and it' was the end.

 not access the Bios, no option bootselect not boot from USB and not recognize eRicovery .... dramatic.

 For three days I tried everything.
 This morning, extreme act ..... I removed the body, I removed the SSD memory, I turned on the tablet boot from usb (now I can go into bios and if memory 'removed!) and the installation of USB key starts.

 Now, I started installation (without mounted SSD) but as if I had, at this moment I entered the SSD in the slot, I waited 5 minutes, I restarted the PC, and the next install windows7 from USB Memory took over! !

 To be safe I deleted the partitions and installed clean, but I think "Start Recovery" would have solved the same.

The problem isn't the BIOS, is a conflict with the solid memory of 32gb, the 
bootloader damaged of win8 at the first boot erase the address in the file 
system.
Unmounting it.

Who has courage to unmount the tablet, there are videos on the web on how to 
remove cover to access the internal components, is not 'difficult.

 Requires a USB key drive boot with windows 7.
 A usb keyboard.

 Remove the memory solid (! Attention within the left corner, there is' a tiny little switch, but the rewards will not turn on the computer!)

 If you begin an installation USB and memory and solid 'removed, a normal windows installation begins, PRESS THE BUTTON BEFORE STARTING INSTALLATION, INSTALL THE MEMORY and hold FITTED WITH THE HAND, the windows will detect no', then turn off.

 Now, with the added memory, repeat the installation, and will go 'well this time.

I had this problem and have sucdessfully resolved it.

1. Remove SSD 
2. Buy a msata to sata adapter $15.00 at Newegg
3. install SSD into adapter and then install in a laptop
4. Reformat SSD 
5. Install windows 7 and reboot to ensure you have a good install
6. Remove ssd from laptop and install in W500
7. Boot W500 and F2 at ACER screen. This gave me access to bios again. Hurray!
8. Set USB HDD as first priority for boot and SanDisk SSD as last. Save and 
reboot.
9. I then reinstalled Windows 7 (format HDD)from USB created with Win7 USB/DVD 
Tool from microsoft. This cleaned up the installation and some driver issues 
from the laptop install.
10. Rebooted after Win7 install finished and tablet booted normally.
11. Dowloaded latest drivers from ACER and installed.

Everything is back working.

If anyone still has an issue with a bricked acer Iconia W500 here is the 
solution  and the one that acer uses themselves. The community will need 
someone with a working W500 to follow these instructions and then upload a copy 
of their working BIOS so that those with a flashed BIOS can restore the image 
http://forum.notebookreview.com/toshiba/594618-insydeh20-bios-modding-zone.html 

I have done this and it works unfortunately I no longer have my W500 otherwise 
I would do this for everyone experiencing this issue and upload an image 
because it beats the hell out of sending it in to the manufacturer. Acer should 
have offered a BIOS image on their site just like they do for hardware such as 
the Acer Aspire one and am quite baffled at why they do not.

hi symons

You may be right for the process but its just half of it. It does not show how 
to put the bios in your not working w500. Would you please put some light on 
that or setep down the process followed by you.

Presently my out of warranty W500 is lying in a drawer from last 3 months as 
it’s in the same state as many of the people above. After installing android 
it didn’t boot up. Have tried every option available on the net till date. 

Which includes taking apart the w500, formatting and installing new os(win7, 
win8, ubuntu, android, dual boot, even tried my NAS os)in SSD. Had bought SATA 
to mSATA adapter from ebay which took 40 days to reach me from china...(look at 
my patience...:)). Have even tried cutting one terminal of cmos battery and 
resoldering it. but no luck. Just few days back got hand on service manual 
which explains the process of reflashing the bios with the bios available in 
acer website but that does not seem to work. have only tried once. It also 
shows the cmos reset jumper (yes W500 has one) which is next to the processor. 
Will have to take the heatsink out for that and thats the last resort which i 
am having. In last 3 months have gone to every nook and corner of the web, 
insyde bios, acer blogs etc. 

My only submission after this experience is never mess with acer stuff. Have a 
acer one which is presently substituting to the work of this w500 and now I am 
even scared to upgrade the os on this baby…:).

If you are interested in the link to the service manual. Search for EAB00X64.fd 
in google and you will get the guide in mycomp.su.

Do let me know if anyone gets thru with this.
