Hi All,
I have an ATT Atrix and I flashed the 2.3.4 beta from http://forum.xda-developers.com/showthread.php?t=1159385 and forgot to unlock the bootloader. I already have the 1.8.3 radio. Right now the phone froze on Dual Core Screen. I guess this has something to do with not unlocking the bootloader. The phone can still boot to fastboot, the original Android recovery and RSD. But, It won't flash all roms I downloaded saying the signature validation is incorrect. And I tried to flashed the unlock sbf and try to unlock the bootloader. And the RSD lite kept saying unable to retrieve interface and thereby failed.
What do I need to do on this case?
Thanks for you help!!! Sincerely!!!!!!

I would get it into RSD mode (Press and hold power button and volume UP key at the same time, hook it up to your computer, run RSDlite and flash the stock 1.2.6 located HERE!
since you have not unlocked your bootloader AND you used keneths ROM I do not think you can HardBrick your device flashing backwards considering you weren't successful in flashing forwards.
But just in case.... You are responsible for using any dumb ideas I might have!
Next time, please post in the Q&A section as no one likes to see this stuff in the Developers section
Thanks for replying so quick, I will try it out!!! Thanks very much!!!!!!
The flash to 2.3.4 would not work without unlocking the bootloader. Try a factory reset/wipe then RSD as stated above if the wipe doesn't work.

Ok would say wrong section but I got time to maybe help.
Just boot into CWM and flash fruitcake 1.8.3 zip. Wipe before flash, this should boot.
I cannot boot to CWM somehow...

Note: Once you unlock your bootloader you can never use the method that I outlined for you when flashing back or forward. Just uninstall RSDLite and forget all about it or you will HardBrick your device leaving you with a very expensive paper weight

I bought my Atrix not too long ago and it came with android 2.2.2 and fully upgraded. Anyways I searched all over the forums and google and found nothing.
I followed these steps shown in a guide at briefmobile but the flash always fails because mine shows up as "SE Flash Olympus" and not "NS Flash Olympus". Does this mean I cant unlock the bootloader to instal 2.3.4? or is there something I'm doing wrong?
In the early atrix days it was rumored that NS meant non-secured and SE meant secured. Sadly, all our devices were indeed running a locked bootloader. Perhaps try flashing pudding , the preinstall sbf or the hktw leak? Maybe in your case you have an unlocked device already (not really i guess but your phone is different)
It looks like you're right. My phone has already been unlocked. Thanks for the reply!

Your notes on how you fixed this saved my phone (and my sanity!) Thanks for taking time to post it.
Note, what I used to unlock and load the recovery image is on atrix4ghacks (it won't let me post the link) but it is labeled How to Unlock Bootloader and Install Permanent Recovery!
Looks like it lost everything and reverted to 2.2.2 but that's much better than a brick any day

Okay guys, i flashed the 2.3.4 ota as soon as it came out (before all this trouble with it of course) and now i am stuck because i was under the impression that the new bootloader would be unlocked so i had never even though about eating any pudding before the fact. Now i come to my trouble, im running a totally stock 2.3.4 att and i cant seem to find a way out.
Question #1- If i have a locked bootloader can i fruitcake back?
Question #2- Is there a possible way to unlock the new bootloader?
Question #3- How in heck do i get root, im on windows 7 and i recently tried the two bat files that one of the devs released and they were a no go, it didnt seem to flash the preinstall when i tried to look for it, it wasnt there. I have been quietly trying to fix this on my own for days now i am asking for a little help. Im stumped.
I got root using the /preinstall method with those 2 .bat files posted yesterday.
From page 30-35 is the guidance I followed from mramirezusa.
Other than that we are in the same boat.. I read puddings will flash relatively safely.http://forum.xda-developers.com/showthread.php?t=1159950&page=30

hey man first things first. dont panic, you are not stuck. this is temporary at best, in the mean while theres plenty of stuff you can do, sbf is not safe to begin with. so actually be gladd you only got to use RSD one time
first things first, get yourselfed unlocked, pudding will do the trick. once after pudding, you never have to touch RSD
Once you are done with pudding go ahead and get tenfars unlocked cwm
once you are done with that you are free to flash pretty much all the roms, as usually custom roms, or fruit cakes dont have bl, only the rest
enjoy
Okay guys, thanks for your help. but let me get this clear, i do not have a unlocked bootloader, im a pudding virgin. I can simply rsd the 1.83 with pudding and thats it? No worries no nothing?

Yes but you still can't use any other sbf. I'd use the raw pudding sbf, unlock, then use CWM from here on out. No more rsd
Sorry about that. There is just the unlock and then the unlock packaged with 1.8.3. The one that has has been causing bricks from my understanding is the packaged one. Be sure you flash just the unlock.
Anyone know what exactly will be erased from /data after flashing the unlock? Also I don't want to restore backed up files that will conflict with new ones. Any guidance on this is appreciated.

All user data is wiped when unlocking. The 1.8.3 sbf with pudding is safe to flash but i recommend just using pudding and then CWM and ditch rsd.

Agree, just use the pudding only sbf. to unlock , then preinstall to get root.
Make sure to have 50 or so battery so you don't run into the trouble I had with battery being to low to fastboot. Also once you flash pudding you wont be able to boot the phone, don't panic just follow steps to fastboot oem unlock and phone will boot fine afterwards.

Which did you flash? Pudding or 1.8.3 with pudding?
Try connecting your phone to pc select fastboot and finish the pudding instructions (fastboot oem unlock)
It might boot then.
Sent from my MB860 using XDA Premium App
Here is what I did.
1. If you were to update to the OTA 4.5.91. Or already on the OTA 4.5.91 you can still unlock your bootloader.
2. Flash pudding only SBF so you can unlock the bootloader. http://diamantephoto.com/fastboot.rar direct link. Flash this one.
http://forum.xda-developers.com/show....php?t=1136261 Original Post about pudding.
It will go to a text only 14 option screen and say something like boot failed 0x1000. Don't freak out and tell me you bricked you phone blah blah blah. You still have to unlock the bootloader by choosing fastboot from your phone and connecting it to the computer via usb. Make sure you have ADB with fastboot tools installed on you computer.
Open command prompt from you computer and type fastboot oem unlock. It'll display warning about voiding warranty and a unique device id. Type again fastboot oem unlock ############. The # are the unique device numbers. Don't type # it wont work. The instructions are posted on the pudding thread if you would like to read more about it.
Then type fastboot reboot to reboot. Unlock should be displayed on top left of screen and it'll take 5 long mins to boot up.
3.Then you need to install CWM and root.
You'll find instructions in the developers form. But if your lazy here is the CWM link. http://forum.xda-developers.com/show....php?t=1138541 follow the instructions or every time you reboot you will loose CWM. For root there are two available for gingerbread. http://forum.xda-developers.com/show....php?t=1140110 I used this one and got root.
http://forum.xda-developers.com/show....php?t=1138204 I hear this works too.. Haven't tested read the post if you want to use this method.
As always don't blame me for bricking if you happen to do so. DO IT AT YOUR OWN RISK. these are the steps I took to unlock and everything works great. Absolutely no problems with my phone after wards.
One thing unlocking your bootloader will format/erase data. Basically a factory data reset so make sure you backup everything with titanium or you favorite app. I would not restore system apps as i've had a few problems with email and motoblur force closes.
Is there a way to root without unlocking the bootloader?

Hi All,
I have an ATT Atrix and I flashed the 2.3.4 beta from http://forum.xda-developers.com/show....php?t=1159385 and forgot to unlock the bootloader. I already have the 1.8.3 radio. Right now the phone froze on Dual Core Screen. I guess this has something to do with not unlocking the bootloader. The phone can still boot to fastboot, the original Android recovery and RSD. But, It won't flash all roms I downloaded saying the signature validation is incorrect. And I tried to flashed the unlock sbf and try to unlock the bootloader. And the RSD lite kept saying unable to retrieve interface and thereby failed.
What do I need to do on this case?
Thanks for you help!!! Sincerely!!!!!!
There is a way around it it isn't easy.
There is a post back in dev section. DO NOT FLASH ANY RSD FILE TO YOUR PHONE AT ALL YOU WILL HARD BRICK IT.
Sent from my MB860 using XDA Premium App
So Guess who got an Atrix today? me! Guess who also probably bricked their atrix today? me!
So here is what happened:
1: I have an unlocked, rooted Atrix 4G from AT&T running 2.2 1.5.7 I believe.
2: I wanted to flash some roms, so I so I attempted to flash tenfar's CWM, but that didn't work, it said install succeeded but I could not get into CWM ( I tried everything, believe me, I'm no noob)
3: I then attempted to flash CWM from Rom Manager and so I did and I flashed the Atrix version, I then hit boot into recovery from within Rom Manager.
4: What I got next is a screen that says "failed to boot 2, starting RSD mode", now I cannot get passed that screen when it powers up.
5: Worst of all, using MSU (moto sw update), it says device is connected but not what kind, meaning I can't restore it, probably because I had adb mode turned on previosly.
update: after attempting to flash a new SBF, the phone told me it failed because the phone did not re-enumerate. Now I have the same problem, but with a new error message on the boot screen: Battery to low to flash!
I have searched everywhere, now I need to resort to you, xda community, Thanks So Much!!!
If you can get into RSD , check to see if fastboot is an option. If you can get into that I would advise to start over by erasing recovery. Command is fastboot erase recovery, then flash romracers recovery thru fastboot. Once you have recovery reboot into it and flash any ROM like Alien, Aura whatever you like.
Alien Atrix
See the thing is, fastboot is not an option , it immediately goes to RSD mode. I may have found a fix, and I am now flashing a new SFB with rsdlite
That's another option, noticed you were on 1.5.7 so I would advise 1.8.3 fruitcake sbf. Make sure you battery is fully charged, if your battery gives out during sbf flash you will hard brick your phone.
Alien Atrix
while I was flashing the sfb, the device failed to reenumerate and now it gives me a low battery warning, with no way to charge it, regardless, I have a friend who will let me borrow his battery tommorrow then Ill try to flash again, really I should use the 1.8.3? I just tried to flash the 1.2.6, so Your saying its ok to go forward with a SFB flash? I come from a world of Samsung's so these are all new to me besides the time I had a backflip for a week (ugh).
Are you sure your unlocked the bootloader? If you successfully unlocked you would have unlocked on top right corner of boot screen and have fastboot also.
Alien Atrix
I'm not sure if I have there is nothing that says "unlocked" at the top of the screen, and I could previously access the recovery and fastboot before this. I did not get this phone new, it came from the AT&T dev center or something like that. My dad works there.
You need to charge the battery. I stripped an old USB cable down and used the red with the positive side of the battery and black with the negative using tape to hold them in place then inserted the battery in the phone and plugged the USB in the computer. This allowed me to flash a ROM and unlock bootloader. Etc.
Warning this could harm you're phone. If you cross the wrong wires or touch more then just negative or positive areas of the phone and or battery. Although I didn't have any trouble with it you might.
If in doubt do it the right way buy a battery charger for your battery, use someone's battery or phone to charge yours.

Ok Im at my computer, If you are unsure of unlocked bootloader I now recommend you RSD either 1.8.3 with unlocker & preinstall or the newest is 2.3.4 with unlocker & preinstall read this thread about 3 times first http://forum.xda-developers.com/showthread.php?t=1136261
Unlock using fastboot, after you get phone to boot for first time, ADB commands for preinstall root, after root use Root Explorer app then delete "install-recovery.sh" @ /system/etc.
Now you are ready to install the newest recovery by Romracer 3.2, Tenfars is outdated and no support from the developer. Read this thread 2 times http://forum.xda-developers.com/showthread.php?t=1204500 I recomend flashing this recovery thru fastboot per Romracer.
Now you are ready to flash your choice of ROM, follow proper procedure to flash new ROMs thru Recovery.
Also check out the unlocked sim codes thread in general, unlock sim.
If I helped click the thanks button
what Im confused on is what exactly i should flash if I am stuck in a kind of RSD mode bootloop/soft brick?
On your first post you said you were on 1.5.7 correct?
Atrix first released with 1.2.6 then updated to 1.5.7 then updated again to 1.8.3
Bootloader was unlocked with the 1.8.3 update
I updated to 1.2.6>1.5.7>1.8.3 then followed this tutorial http://briefmobile.com/how-to-unlock-the-atrix-4g-bootloader[/UR
ok thanks very much! Ill get back to you later once I get a fresh battery.
Ok so I'm about to flash the Pudding .sbf, am I doing this right?

yes, that's what you should have done in the first place. you can't do anything with "ROM" in its name without unlocking your bootloader which is why you're in this predicament. unlocked phone (maybe you mean SIM unlocked, free to use on any carrier) is not the same as an unlocked bootloader.

Need some help please.
I have Telstra Atrix with ota gingerbread, unlocked BL, rooted.
I can't get it to boot into cwm recovery.
I installed ROM Manager from market, flashed CWM 2.0.2.0 , selected Reboot into Recovery but it only gets to the triangle. From there I can hold down Vol Up+VolDown and get to Basic Android recovery.
I have deleted the racing car app as suggested in one thread to make room, but no help.
If I power off and boot it from Power+Vol Down it comes up "Failed to boot 2"
Can't find a solution in XDA or Google. Any help appreciated.
See if you can fastboot flash a recovery image
sent from my Atrix via XDA premium
Most likely need to delete "install-recovery.sh" @ /system/etc, if it's there, then try re-installing CWM Recovery, and see if that works.
Thanks fellas.
Turns out I had lost my unlock BL by flashing the Telstra Froyo sbf from the xda Atrix Firmwares Superthread.
Reflashed the pudding and it's unlocked again. Actually romracer explained it better in his thread. I thought you couldn't relock bootloader. CWM recovery works now.

U can't actually relock the boot loader, it "Burns a fuse" inside the unit when u unlock. But flashing an .sbf makes it appear as if it's locked again.

Yeah thanks. Romracer explained it to me. It doesn't seem to be common knowledge at all. So people flashing sbf's of stock roms are effectively losing root. I spent hours trying to figure it out and get info searching and asking questions. Anyway, all good now and I appreciate the assistance.
On another point do you know how I can get the Telstra radio so I can use it with custom roms? My phone use is way better since installing Telstra stock Gingerbread ota. If I flash another rom I'll lose it won't I? It is N_01.100.00R
Edit: thanks to @Msd24200 and @marko! for pointing out that Radio remains unchanged when flashing cm7. Also discovered where to get the zip of this radio if I lose it http://forum.xda-developers.com/showpost.php?p=15787709&postcount=1
