You can't do that. AT&T phones can ONLY use AT&T firmware. This had been said repeatedly all over this forum. If you and/or your friend would have bothered reading a little you would know that already. Next time read everything related to your (or your friend's) phone. Then read it all again, and even if you think you understand, read it again. Make EXTRA sure you know what you are doing before you do anything. That being said, try to flash the FXZ from the first link you posted. That is, if the phone hasn't been bricked already. If that doesn't work then I'm afraid your friend now has an expensive paperweight. I hope your friend is a nicer guy than I am. Good luck!:thumbup:

You can flash that on AT&T.
!WARNING! This metod is only for advanced users... If don't know what is CID. Don't flash that files!!!

But I don't recomended that... And also DON'T TRY TO FLASH RETAIL A2 FW VIA RSD EVEN WITH ERASED CID!!!

What exactly do you by the method is "working on AT&T A2"? I watched the YouTube video you linked in another post and saw the phone boot up, but then I appears that it is showing an error message.(possibly a force close of some sort. Sorry, I can't read whatever language that was in) Then the video stopped before showing the phone in a usable state. Can you provide verification that the phone is usable after doing what you are suggesting? I ask because to me there is a difference between booting up to endless force closures and booting up to a useable phone.

First: Youtube video is about China 4.1.2 not working - if see youtube video name... (touchscreen not working)!!! ,2nd: Mearet ICS booted fine - if you also seen screenshots under my post. It's says on AT&T kernel builded in 08.31, but Mearet kernel build date is in August 20... JB is in JANUARY...

I see. I must've misunderstood. Thanks for the clarification. So what are the implications of this exactly? Does this mean AT&T owners are not limited to AT&T firmware so long as they back up their CID?

Yes, that means it's same like in RAZR - we can use any A2 (Indian MB865, China ME865 or any A2 kernel)... But different A2 models is different hardware (for example radio chip), so if we flashed ME865 fw via CID erasing we posible will have Wi-Fi disconnection issues & etc...
And also this means that we can convert AT&T MB865 to China ME865 and use Official MIUI on AT&T without battery issues (this is only hypothetic, tomorrow i'll test it).

Hi turffee!
Your device is AT&T Atrix 2?
The bootloader of your device is unlocked?
please put this command to terminal emulator, or adb shell with su
cat /proc/omap_dev_type
If this returns NS, can you share your mbm.img and mbmloader.img?
dd if=/dev/block/mmcblk1p1 of=/sdcard/mbmloader.img
dd if=/dev/block/mmcblk1p2 of=/sdcard/mbm.img
Thanks

My device is AT&T. It HS device. There's one thread with unlocked A2 it returns command to NS. That person also shared mbmloader.bin & mbm.bin for public (only for devs) - also if you'll find that files (thread) DON'T TRY FLASHING NS BOOTLOADER TO HS DEVICE (including all A2) or you'll hard bricked!!!
Also about CID erasing. Then you erase your CID, your device loosing region identification, so you can flash any A2 firmware. Bootloader is still locked, like & many others inxluding Jim's A2, it's just bypassing region...

Actually no, my dev phone is a NS device, and has the correct Efuses flipped, it is NOT just a region bypass, it also has writting all over it stating that it is not for resale.

[Q] Can't change firmware

I already flash "InlineFlashing_Edison_67.21.125_CFC_P3_APBP.xml" from 591.com (I don't remember and found what forum). I really don't know not att phone musn't flash this firmware, then I can't flash any other firmware.
Is there a way to fix that?
PS Sorry about my english.

We need more info: Is your phone AT&T or International (Retail). What did you did? You flashed at&t fw to retail a2? If yes - you're screwed... You should never ever flash AT&T fw to retail 2, because cdt.bin version increases & you cannot downgrade to retail one.
If you done that & have warranty, better is bring to it, they'll couple times try flash retail fw which will fail.. And they will change mainboard. If yours warranty is over, you'll live with that problem... Only temporaly fix is flash kexec based rom (if you aren't kexec reject).

Phone model (Retail India, Retail China or AT&T) & have you flashed other than retail firmware (aka. AT&T)?

Don't worry it can be fixed.
You've hit the problem that many of us NZ users have had. For some reason RSD Lite just doesn't work on the Telecom NZ phones. (Although some users say it worked for them)>

[Q] Atrix 2 from ebay Cyanogen Mod installed, how to flash back to stock?

Hello,
I bought an Atrix 2 at ebay (the seller said it is new), unfortunately there is Cyanogen Mod with Android 4.1.2 installed. If there is any safe way to flash back to stock I would prefer this, instead of sending it back because I live in Europe and bought it in USA .
Could you recommend me an easy secure way to flash back to a stock rom? Unfortunately I don't know where to start.
Thanks,
c.

To be honest, the best thing you can do right now is read. All of this has been covered before, repeatedly, and all the information is readily available as well as easily accessible. What you don't want to do is start flashing things without knowing what you're doing and how to get yourself out of trouble should you encounter any issues. So take your time and browse around the forums and familiarise yourself with the various flashing procedures. You won't regret it.:thumbup:

Ok, ok, you are right so I found these two threads, so I think I know now how to flash and where to find fxz. But I don't know which fxz Version is the right one, my Phone don't have a at&t logo on the cover. I expect that it is a US Version but I'm not sure.

Post a screenshot of your about phone screen. The build date is the give away, on the kernel. When you post that one of us can point out if you have leak one installed.
I will be very honest here, and since you are not sure which stock version was on the phone before, you have a high chance of bricking the phone. If does not have the ATT logo, it does not tell us much. You could still have an HK version of the phone which is as locked down as the ATT one is, or you could have an Asian version, which would be good, since they are not as locked down...
I would tread very lightly here, and I would tell you to just flash another non-stock ROM from the dev section, on it, as that won't brick you.. But you really need to find a way to figure out which phone you have.

What would happen if I flash the ATT firmware, assuming that it is an asian or Hongkong Version will it result in a hard brick or a soft brick?

As far as I can see, there is no custom ROM which has a working webtop, I would like to use webtop. Or do you know any ROMs with webtop? I searched a lot about finding out if it is possible to figure out which hardware is in the device to check which firmware version could be right but I found nothing .

You have AT&T 125 fxz kernel... It builded in 08.31. But you also need to check your imei... And does your phone have any AT&T logo? On box or on digitizer?? It also can be AT&T phone but with Retail Atrix digitizer.... or worse Retail A2 locked down from higher cdt.bin from AT&T fw.

Thanks for the telling me the Kernel Version. Could you please explain, what do you mean by "check your IMEI"? I think you don't want me to post IMEI?
The Phone does not have any ATT Logo, not on the digitizer neither on the box. I saw that the Text on the box is only written in french.
So even with knowing that it's the ATT Kernel, it's not sure if I can flash the ATT firmware:

Reflash HK (with boot failure screen) fw & bring it to warranty & fool it (that it shuted off while charging & shows fastboot err. They'll try couple times flash Retail fw, but it will fail at cdt.bin & most likely they'll replace your board).

If you have the AT&T model, you can ONLY flash AT&T firmware. That's why you're getting an error.

No. The cdt.bin version number (aka burned eFuse) increases to at&t one and can't be downgraded or changed... So you got at&t model forever.

Because that firmware wasn't meant for AT&T phones. Now that you've flashed the AT&T firmware you're stuck with it. There's no way to upgrade, and no way to downgrade. You can still root and flash ROMs though.
