Prerequisite:
1. ATT ATRIX 4G device
2. Windows PC
4. No matter what version you have 1.26 / 1.57 / 1.83 / 4.5.91 (*)
5. Proper USB drivers Installed (You can found them at: http://www.motorola.com/Support/US-E...arging-Drivers)
6. A little of Patience

PROS:
* You will ended with an unlock bootloader (BL)

Procedure:
1. Download the attached file
2. Unzip the file inside of a new folder on your hard disk
3. Now is time to run the magic, go to the folder you just unzip the files in and double click or run "MAIN" file
4. A new windows DOS box will show up and just follow the procedure!
5. Flashing pudding part will take a little longer so be patience and let the magic do their work
6. At the end of the process your phone will reboot automatic.
7. Enjoy it!

Thanks to the2dCour for pudding sbf
Thanks to Tenfar for CWM (I prefer it due to the ABD option in recovery! NICE)
Thanks t0dbld for Mobile Hotspot patch

(*) Some users with 4.5.91 will need to run "fix" file to recover from a softbrick after the first attempt
(*) It seemd the new 2.3.4/4.5.91 pudding do a wipe after flash it, so have a backup just in case (I tested 1.83 and at least this preserve the data)

Once you unlock your bootloader - you cannot reverse it - its permanent... you can never re-lock it.

Wrong... you can return to stock using fastboot and RSD image.

No , actually technicaly it Burns through a fuse. So you can make it appear locked however it will never trully be re locked again. ( they don't usually look for the fuse) so that's why it isn't a worry topic.

One unusual thing is once you flash an sbf (or at least when I have flashed the 1FF-olympus-user-2.3.6-4.5.141-111212-release-keys-signed-ATT-US-GAS_NA_OLPSGBATTSPE_P012) you must go through the steps of unlocking the boot loader again.When you complete the steps it tells you it was already unlocked.The phone would not let me flash a custom recovery until those were redone.

Word of WARNING! Only flash SBF files if you enjoy the challenge of soft and semi hard bricks. Have received Failed to Boot 1 many times.

Unlock bootloader Atrix 4 G (from ebay, non AT&T)

Good evening,

After long time reading stuff about, I finnaly got the courage to root my atrix with SuperOneClick 2.3.3 and it all went fine.

The idea is to Try the Neutrino ROM 2.9

I buy it unlocked on ebay and i am using Vodafone network on it.

With "Root Checker" i have this info:
BOARD: olympus
BOOTLOADER: unknown
BRAND: MOTO
ID: 4.5.2A-74_OLE-31
MANUFACTURER motorola
MODEL mb860
PRODUCT MB860_VFDE
RADIO unknown

In "About Phone" i have this:

system version: 45.31.0.MB860.Vodafone.en.EU
Android vs: 2.3.4
Baseband version: N_01.100.00R
Kernel version: 2.6.32.9
APflex version:
GAS_EMEA_USAOLYPGBVFDE_P020
GAS_EMEA_USAOLYPGBVFDE_A006
GAS_EMEA_UCAOLYPVFCOREEU_M001

build number:
4.5.2A-74_OLE-31

---

Now my questions and fears:
1º is my bootloader unlocked? (i think not)
2º wich procedures shoud i take to have neutrino rom safely?

provably the answer is allready somewhere in the forum but i am afraid to brick my ATRIX, so i'm asking here hoping someone call help me before i do it on my own based on the information i read.

thanks in advance for all the help,
Luis

If it was all stock and you only rooted it, why would the bootloader be unlocked?

As mentioned countless times before, you need to unlock the bootloader, install a custom recovery, then install whatever ROM through the recovery. Do a little searching, this has seriously been covered many many many times.

I've searched and searched, all I found was guides with dead links since it's been almost 5years now since they were posted. Does anyone have the required files for unlocking the bootloader? I get an error anytime I try to install the 4.0.4 update. The device just aborts installation and reboots

SBF File Needed

I am also looking for the correct SBF file that can be used to unlock the bootloader of my Atrix 4G. I have search everywhere for a valid link to download the file and have been unsuccessful so far. I have the following:

Model Number: Atrix 4G
System Version: 4.5.141.MB860.ATT.en.US
Android Version: 2.3.6
Build Number: 4.5.141
Carrier: AT&T

If anyone could provide a valid link to download this SBF file I would greatly appreciate it.

Thank you!
