Flashhack - New LT1 flash tool

**Casey96SS** · 08-20-2020

@steveo I am getting an error when writing bins to my PCM. Seems to have something to do with patches. I unapplied any patches I did have and now am only running the BLM locker. I get an error that says cannot install recovery ROM on T side. If I uncheck the setting in Flashhack about Verifying patching regions against reference it writes with no problem.

Is this anything I should be concerned about or need to fix? Thanks!

Are you using the latest XDF from Steveo’s website in TunerPro? If so you shouldn’t get that error.

That said, it’s nothing to be overly concerned about—the recovery patch is just a safeguard against a failed flash, we’re such a thing to occur. Without it your vehicle will run just fine, you just need to make sure the flash sequence completes successfully.

The error stems from Flashhack being unable to guarantee that the Recovery ROM won’t overwrite one of the patches you applied in the XDF. If you’re using the latest XDF from Fbodytech, this problem shouldn’t occur.

it's probably nothing, but i would recommend you uncheck 'install recovery rom on tside' rather than 'verify patching regions' until we figure out what's going on. you should post the bin that it's complaining about and i'll try to have a look at it later.

the recovery rom is probably only helpful if you totally lose ECM power during a flash write

if you uncheck 'verify patching regions' what you're doing is forcing the recovery rom patch no matter what. we don't know why it's throwing that error but something is different about your bin. the reason i wrote flashhack to be so picky about it? if we run into a bin that's been altered in a way we don't anticipate, the recovery rom might prevent it from booting, and that would brick it.

Thanks for the replies guys. Yes running the XDF last modified on 5/16/20 in TunerPro.

Attached is the most recent bin that I loaded. Thanks for any input!

kur4o can you look at this code segment and see what's going on in his t-side? there might be other differences but these ones stick out.

there are differences at 0xB9DB.. the factory bin has:

Code:

8B 85 40 27 03 14 85 08 39 B6 01 9D 81 03 24 08 FE

this guys bin:

Code:

8C 85 40 27 03 BD 3C 89 39 B6 01 9D 81 03 20 0F FE

also at 0x4311. normal bin:

Code:

15 02 40

this guys bin:

Code:

BD FF 85

is this one of your patches or something else? i looked through a few factory bins and don't see any like that.

I checked the bin and it does have some patches. Couldn`t figure which one. It does have some meta data of engine specs.

It looks like the bin have the mini rom patch too. I guess it was flashed with flashhack and than read back.

Only the owner of the bin can shed some light about the mods being done to the bin.

having same issue here, one of my customers bins was read and flashed by EEhack flash tool like year ago (some tuning done and applied patches from EEX def file, now wanted to flash modified one (some spark and trans stuff) and recieved same error.
