I have managed to softbrick my Atrix 2 (I do hope it's ONLY a soft brick...).
I'll try to describe my situation as accurely as I can:
First the current status of my phone - When I turn it on it boots, and I can even call it, and it will ring, and I can answer! - but the screen is off, and the phone is practically unusable...
When I connect the phone through USB to my PC, RSDLite recognates it, and I can try to flash firmwares from there (and also using the moto-fastboot commands directly).
It seems that the screen is off even through the bootloader phase - it dosen't show the Moto logo when it boots at all..
One time I did manage to boot it, and the screen was ON - but after a few hours it whent pitch black again...
Now I'll describe what led me to this situation:
My atrix 2 was bought online from ebay - from an Honk Kong store (I live in Israel).
It doesn't have any AT&T logo on it, and under it's battery it has these details written on it:
And some more numbers... (If this has any use for somebody I can attach them as well).
From RSDLite this information is printed to me:
Software Version: 6.7.2-226-EDICS-10
Flex Version: NOTAVAILABLE
Bootloader Version: 0a72
DRM Version: N/A
At first it was running the official ICS firmware - but I don't know which one! I didn't know that it was important to know what version if first arrived with - So I rooted it, installed the A2 bootstrapper, and through it Installed PA3, including the needed Gapps.
It was running just fine with PA3, but I preferred returning to the originaI ICS firmware, cause it was faster to me.
OK - now this is were things started to go wrong -
It seemed that I needed to know what was the original ICS Firmware that my phone had come with, inorder to download it from here (sbf.droid-developers.org/edison/), and flash it through Fastboot using RSDLite.
So because it came from the Hong Kong, I thought it might be MEREAT, or SEREAT - And I just tried flashing this version:
Blah... it was resulted in Failed to flash firmware: cdt.bin - phone returned FAIL.
And now my phone was stuck in Fastboot failure screen.
OK - I thought, this was probably the wrong firmware, i'll just try a different one.
Now I don't remember the next steps I did, because it was all kind of stressfull - but I just tried flashing all the mideastern ICS firmwares (and maybe also the GB firmwares as well) - and non of them worked (all failed the same - with cdt.bin failure).
Now the screen had gone OFF, and I became realy woried that the phone was hardbricked...
Luckely - despite the screen going OFF, it was still (and is still) showing up in RSDLite, and I was able to try other firmware's to flash, hoping I would eventually end up with the right one!
Some where in a post about how to downgrade to ICS, I read that someone failed to flash any firmware, but the InlineFlashing_Edison_67.21.125_CFC_P3_APBP.xml.zi p one. So despertely enough, I tried this firmware, although I didn't think my Atrix is running AT&T US firmware originally...
Somehow this firmware flashed! but the screen was still off....
Later I tried to flash using Altered restore-to-ics scripts (using the moto-fastboot command) - And with it I successfully flashed p3_edison-edison-user-4.0.4-6.7.2_GC-220-EDS-3-65-release-keys.
But still...the Screen IS OFF....
Any help would be highly appriciated!!!!
