Greetings everyone,

This is my second time flashing heads rom, the first one with x230 that i dont have problem. and recently i bought t430 and just doing flash without having backup top rom.

I can read both chip, also can write top but not with bottom chip.

i have try prebuilt rom rom from circle ci, it was from latest commit :

UNTESTED_t430-legacy-flash
Since there's no bottom rom, so i assume that it will work but nope, after powering up, just after 1 second, fan stopping, power led up, and its like the pc just shutting down.

UNTESTED_t430-legacy
Havent try it since it was 12MB, so i assume i cannot use this rom.

UNTESTED_t430-hotp-legacy
Havent try it since it was 12MB, so i assume i cannot use this rom.

t430-hotp-maximized
I can succesfully write top rom, but not with bottom rom, also have try using all the chip* but no success. (havent try to boot up but i assume flashing top only would likely fail?)

t430-maximized
I can succesfully write top rom, but not with bottom rom, also have try using all the chip* but no success. (havent try to boot up but i assume flashing top only would likely fail?)

Chip found for top is : Found Macronix flash chip "MX25L3205(A)" (4096 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L3205D/MX25L3208D" (4096 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L3206E/MX25L3208E" (4096 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L3233F/MX25L3273E" (4096 kB, SPI) on ch341a_spi.

And i was using MX25L3206E/MX25L3208E for all rom flash.

Chip found for bottom is : Found Macronix flash chip "MX25L6405" (8192 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L6405D" (8192 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L6406E/MX25L6408E" (8192 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E/MX25L6473F" (8192 kB, SPI) on ch341a_spi.

There's a problem with this, sometimes it was found this chip, and sometime it will changed, like top chip, its weird, sometime it not found, so i suspect the flashing fail its because the bottom chip problem ? I can assure the ch341 is fine, because this was i used to flash x230 too. for about 100 times reading bottom chip 70% is goes to above chip and the rest is this chip:

Found Unknown flash chip "SFDP-capable chip" (8192 kB, SPI) on ch341a_spi. Found Macronix flash chip "MX25L4005(A/C)/MX25L4006E" (512 kB, SPI) on ch341a_spi.

I use all the chip available but no success (everything that comes with MX25L64*).

Apparently at least some data has changed.
Your flash chip is in an unknown state.
Please report this to the mailing list at flashrom@flashrom.org or

So i hope there's a hint from you guys or, please provide the stock top rom, so i can try save this laptop.

The behavior you see is typical of a clip wearing out: the clamp slowly slides out and eventually looses grip where erase function fails and connection being loose fails to detect correctly and different erase functions are attenpted; same happening with detection where if I recall well, generic chips are stated last.

I would recommend changing your clip, I doubt your ch341a is at fault.

You indeed have to flash both top and bottom images which are spitted from the whole 12mb image to be flashed externally. Flashing top is indeed insufficient.

Closing as I can't fix this: this is a mechanical problem you are facing that needs a clip replacement. You do not see the same behavior on the top chip simply because the loosening of the clip doesn't happen in the smaller time lapse needed to flash 4mb as opposed to 8mb on a slow link.

Oh.

And as documentation specify, you want maximized version. Choice here is between dgpu or not, hotp or not.

If that is unclear from doc, please open issue under heads-wiki repo, this is not code related but would be documentation related therefore heads-wiki related.

will using stock top rom will fix the problem, do you have it as backup ? can i try ? i just want to make sure the board isnt faulty

I don't. Guide specifies to backup first. Change clip and flash bottom rom.
