R4i Gold 3DS Rev 7 (www.r4ids.cn)

[Leadger69]

I've dumped and flashed ntrboot but when I try to run it on my other 3ds it won't boot into safeboot. But when I try the ntrboot flasher 3.0 it says that flashcart is not supported

This has my GM9 trim and untrim also my flash dump https://ufile.io/q7k4w Any help to get this to work would be great thanks

From my initial examination, that looks to be identical to rev6:

https://github.com/kitling/flashcart_core/issues/9#issuecomment-325106067 ntr_blowfish_retail = 0x0 (plain) b9s_payload = 0x80000 (enc) b9s_header = 0x1FFE00 (enc) enc = same memecrypto as latest r4ids.cn versions

Your backup.bin also has ntrboot injected for the latest r4igoldcn versions (i.e. b9s header at EE00), which of course won't work in your case. Hope you have a clean backup somewhere before you attempted to flash it (might be able to use a clean rev6 if you're lucky).

[Leadger69]

No unfortunately I can't seem to find my clean backup...so I guess that mean I'm screwed

[zoogie]

You should still be able to flash ntrboot provided we can figure out your card. Just going back to running your card as a DS flashcard MIGHT be off the table. Read that last sentence of the OP.

I'll try to make a backup.bin later for you to test as an ntrboot card if you're willing.

[Leadger69]

I'll test anything..i don't mind

[zoogie]

backup.zip

Alright, try that. Just put the file in sdmc://ntrboot/ and select "restore flash" with the following tool: http://s000.tinyupload.com/index.php?file_id=00664373029281777476 Don't choose "inject ntrboot" under any circumstance and make sure to name your payload ntrboot.firm

[Leadger69]

It detected it fine as r4i gold 3ds and backed up fine as well..but it doesn't load as a ds flashcart

[zoogie]

@Leadger69 - that backup.bin was intended to be an ntrboot enabling flash, not a DS flashcard restoration. The icon will show up as blank on home menu and it will not launch DS flashcard mode -- ntrboot disables that.

[Leadger69]

Sorry my bad...but it still didn't work no safeboot

[zoogie]

Ok, try this one: backup.zip

Same directions as the last one.

[Leadger69]

nope still no boot

[zoogie]

What exactly is happening? Is the system turning off, booting to home menu etc. Did you rename safeb9sinstaller.firm (or some other payload firm) to ntrboot.firm and to do the correctkey combination + magnet?

Anyway, if you did all that and still no luck, you could try restoring DS flashcard compat by reflashing this. http://s000.tinyupload.com/index.php?file_id=04706518342023310360 Let me know if you get some icon and if it boots (you will need a hacked 3ds or maybe dsi to boot it).

[Leadger69]

it stays off untill i move the magnet then boots home screen.also does the sd card need to be in the flashcart and I thought that you rename the safe.firm to boot.firm

[zoogie]

No, you need to rename safeb9sinstaller.firm to ntrboot.firm as I said above. The microsd does not need to be inside the flashcard for ntrboot. The 3ds system itself needs an sd card of course.

[Leadger69]

Sorry for the no response I was at work I tried all the things in the op but still no safe boot..so I tried the other file and now the card is back to normal with screen and boot like a regular d's flash cart on my backed 3ds

[zoogie]

Well that's certainly good news. At least we know that rev6 and rev7 should be essentially identical. Sorry we couldn't get ntrboot to work on your rev7, but we'll keep trying.

[Leadger69]

well at least I'm helping to figure stuff out

[Leadger69]

Any progress yet

[zoogie]

@Leadger69 please flash https://github.com/kitling/flashcart_core/issues/75#issuecomment-335318958 again.

boot with the ntrboot combo, then immediately run godmode9 and dump MEMORY VIRTUAL -> arm9.bin. should be a 1MB file. Upload that please.

It's really difficult for me to debug this without having the cart on hand.

[Leadger69]

Sorry but what do you mean by ntrboot combo

[zoogie]

Sleep + Start + Select + X then press and hold power

[zoogie]

Try and use this version of godmode9 https://github.com/d0k3/GodMode9/releases/download/v1.2.8/GodMode9-20170729-114727.zip

rename it to boot.firm and put it on the sd card

[Leadger69]

Oh so do that on my stock 3ds then put the flash card back into my cfw 3ds and dump the arm9.bin

[zoogie]

No everything needs to be done on the cfw one.

[Leadger69]

there is a arm9.mem but no arm9.bin

[zoogie]

yeah it's arm9.mem forgot

[Leadger69]

https://ufile.io/nm2r0 there you go

[zoogie]

Alright, I've got to go to bed but I'll look at it later today and get back with you.

[Leadger69]

Sounds I'm gone to bed too night shift

[zoogie]

@Leadger69 it looks like you don't have any ds card inserted :/ No trace of a header anywhere.

Did you

1. restore the backup.bin I mentioned above. https://github.com/kitling/flashcart_core/files/1370192/backup.zip
2. Rename that particular godmode9 I linked to boot.firm and put it on the sd card root. https://github.com/d0k3/GodMode9/releases/download/v1.2.8/GodMode9-20170729-114727.zip
3. insert your r4iGold into the system.
4. ntrboot into godmode9 and dump arm9.mem.

The only other issue I can think of is contact issues. Make sure the contacts are clean and a dump doesn't read zero's or whatever.

[Leadger69]

https://ufile.io/1ap9r how about this one I think the magnet was in the wrong place

[zoogie]

Still no trace of a DS header.

Lets try a different track. backup.zip Restore this backup.bin and tell me if you can boot the card in ds mode on your cfw system.

[Leadger69]

i backed it up but when i put it in my 3ds it freezes and wont turn on

[zoogie]

Damn, it was worth a shot. Thanks for testing, will let you know if I can think of anything else to try.

[Leadger69]

alright sounds good..thanks for the help

[zoogie]

@Leadger69 Another little test if you're still around. Make sure https://github.com/kitling/flashcart_core/files/1370098/backup.zip is restored to your card then run https://transfer.sh/OyjwV/fctester.firm That will dump ntrboot.nds to your sd card root. Please upload that if you can.

[Leadger69]

I restored the backup then ran fctester.firm then my cfw 3ds says "ntrcard_begin_key1 failed: -1 0 7EAA0AB2 press B to exit

but here is the file: https://ufile.io/7gvjk

[zoogie]

More testing if you're up to it.

Ok, make sure this backup https://github.com/ntrteam/flashcart_core/issues/75#issuecomment-335318958 is flashed (if no icon appears then you don't have to flash anything)

then run https://github.com/ntrteam/dsfirmverify/releases/tag/v0.0.3 unfortunately you need a ds lite or phat for this to work and two ds flashcards lol. One card could work but you'd need to flash your ds mode to the r4iGold with the 3ds, run this dsfirmverify, then flash the ntrboot backup.bin with 3ds, then complete the hotswap and press A. That's a lot to ask I know :/

And tell me the result displayed.

[Leadger69]

I did it and it says ncgc_nbegin_key1 failed: -2 0xDC306FB7 0xF132C84E don't know what that means..lol

[zoogie]

I don't know either. Maybe @angelsl would know but he has his hands full with other stuff most likely.

btw - https://gbatemp.net/threads/r4igold-r4ids-cn-rev-6-7-8-offering-ntrboot-ak2i-or-20-eshop.488295/ tl;dr I'm looking to buy a rev 6-8 r4ids.cn off of somebody. I honestly think this is the only way I'll be able to figure this card out. :/

[angelsl]

@Leadger69

Did you remove and reinsert the card fully when it told you to do so?

The two hex numbers are the chipid it got from raw and from Key1 mode. Both look like gibberish, so..

[Leadger69]

I'll give it a try again later and post the findings

[Leadger69]

I'm getting my friends acekard 2 version 2.1 tomorrow so I'll try the 2 flash cart method hopefully this will work...lol

[twocows]

Similar situation here. I was able to revert it back to a working flashcart since I already have another hacked 3DS, though. Looks like the cart I have is a rev 7 since that was the backup that was able to get it in working shape again (and coincidentally the first one I tried).

zoogie, did you still need a card? If so, are you located in the US?

[zoogie]

@twocows I might. Right now I should be able to have a rev6 on Monday. Give me a couple of days after that to see if I can get anything working and produce something for you guys to test.

[twocows]

Actually, this is my bad, I didn't realize this was for the revision 7 non-RTS version. I'm using the revision 7 RTS version. This has to be user error on my part, though I can't for the life of me figure out how.

[zoogie]

@twocows a rev7 is a rev7 as long as r4ids.cn is the url on the front sticker and a "7" on the back connector pin.

[twocows]

Edit: it's actually the new r4i Gold RTS Plus, which operates a bit strangely; it has an internal switch to change modes.

[zoogie]

@twocows Yeah that's definitely not a rev7. That's an A7, something totally different. (i think those are rev9 or C).

[Leadger69]

Did it again and it says ncga_nbegin_key1 failed:-2 0x00000000 0x0E112A02 don't know if this helps

[zoogie]

@Leadger69 Got it fixed on rev6 (#9) so it should work with this rev. as well. https://gist.github.com/zoogie/bc4edb08c8e9fce6276b22562424f9b0

If you can't figure out how to use that script I can probably provide you with a binary to test tommorrow (tues).
