Stock ROM 2.3.6 relock/unroot BACK TO STOCK ROM

[photobuddha]

Hi All,

Here is the way that I have used to recover from boot-loops,soft-bricks, and CRAPPY ROMs. Returns phone back to factory boxed condition.

1) Start up RSD Lite
2) Reboot phone in to RSD support and connect phone to PC via usb
3) Select SBF in RSD. You can download STOCK ROM 2.3.6 here http://www.filefactory.com/file/79zd...PE_P012.sbf.gz
4) Be patient it takes some time for RSD to complete the flashing. Leave it along when it's done your done and your phone is ready to use.
5) Locked boot loader and rerooted( bootloader on my phone ) You might still be unlocked if your efuse is tripped

Requirements:

1) Motorola Windows drives
2) RSD lite 5.6
3) USB cable
4) SBF file 1ff-olympus-user-2.3.6-4.5.141-111212-release-keys-signed-ATT-US-GAS_NA_OLPSGBATTSPE_P012.sbf
5) Patients
6) Battery charged
7) Atrix ATT/USA

USE at your own RISK.

Good luck

One correction: this method may remove root and return you to a stock ROM, but it does not re-lock the boot loader. Unlocking the boot loader trips a hardware "fuse" that cannot be reversed, period (except maybe by Motorola technicians). Re-flashing the stock SBF may remove the "unlocked" message from the boot screen, but that's merely cosmetic: once your boot loader is unlocked, it's unlocked forever. Just wanted to make sure that was understood so that others won't get the impression that the boot loader can be re-locked.

Definitely use at your own risk as this file may or may not be for your phone. Also note that your phone will not be locked, as this is an irreversible process.

Photobudda....please indicate which sbf file you've linked. It will not work universally, so knowing which sbf file you're linking is vital.

The SBF is from Motorola it's the stock SBF file. The file name is 1ff-olympus-user-2.3.6-4.5.141-111212-release-keys-signed-ATT-US-GAS_NA_OLPSGBATTSPE_P012.sbf. It does relock the bootloader. I have to unlock my bootloader after applying with RSD. I thought the same thing about the bootloader message just missing but it was relocked. I could not load any roms after loading this SBF.

Photobuddah, I'm no technician, but it is *impossible* to re-lock the bootloader on an Atrix 4g, once it's been unlocked. To borrow a quote from post #2 of this thread "Unlocking the boot loader trips a hardware "fuse" that cannot be reversed, period (except maybe by Motorola technicians). Re-flashing the stock SBF may remove the "unlocked" message from the boot screen, but that's merely cosmetic: once your boot loader is unlocked, it's unlocked forever."

I understand completely but after applying this SBF my bootloader was looked. I applied it again last night and sure enough it was looked afterflashing. I can offer that maybe I have a phone that some how did not get the efuse tripped. I don't want to mislead anyone, this is just my experience. I hope this helps some people that just want their phones working like stock(stable) again.

You phone is and isn't locked. It's unlocked in the sense that Motorola can see that the fuse is tripped and that is what would void any warranty, but it's not able to access the boot loader in the current state and would require you to unlock the boot loader again in order to fully utilize it.

I know it appears to be locked, but it can still be found to "have been unlocked" previously a few different ways. First, you will never have to give the command "fastboot oem unlock" again since the first time is irreversible. You can also find a more in depth look here: Give me your FUSES! For rooted users, froyo OR gingerbread, locked or not survey

It truly is permanent and the "not being able to flash ROMs" is like a band-aid over a scar.
