[Motorola Droid RAZR] thegeologician:
Hi, I unfortunately don't know a lot about what I am doing here (the root of all my trouble), I'll try to get the info straight:

Motorola Droid Razr (XT910), bought in Dubai, using it in UK, so I didn't receive OTA updates. I decided to try update to ICS using RSD Lite, but the flashing got stuck at system_signed. I gave it a lot of time (hours) before I switched off the phone and tried again, which is when things started going haywire:

During my following attempts, the battery ran low, so I couldn't go on trying (soft brick). I made a patched "factory cable" as per instructions in this forum somewhere, the cable works and powers the phone for flashing.

Now all it does is coming up with the fastboot screen, which reads:

AP Fastboot Flash Mode (S) (Flash Failure)

0A.6C

[...]

Device is LOCKED. Status code: 0

Battery OK

OK to Program

Transfer Mode:

USB Connected

...which suggests to me it would be ok to be flashed, if only I could get it to accept the files. Being a big numpty, I am unfortunately not quite sure what was the exact version that was on there before (big mistake, I know that now), it was 2.3.6 and I suspect it must have been a MEA version, since it was bought there(? - also, when I first switched it on, all was in arabic).

What I have tried so far was:

* using several different fastboot firmware files with RSD Lite 5.7, all of which do not get over the step '1/xx flash cdt.bin "cdt.bin_signed"' - it just hangs supposedly "In process..." forever. I noticed all of these have an "ota" folder (although they vary considerably in size between <1 and 2.5 GB) - maybe all the ones I downloaded are only updates? Is there an actual, base operating system image somewhere?

After many failed attempts, I got desperate and tried files for different regions at random. The ones I tried so far:

SPDREM_U_01.6.5.1-73_SPU-11-M1-2_SIGNEuropeAustraliaEMEA_USASPDRRTGB_HWp2b_Service1FF_fastboot.xml

SPDREM_U_01.6.5.1-73_SPU-11-M1-2-ULB_1C.85P_0A.6B_DATDE_CFC_HWp2b_SIGNED.xml

SPDREM_U_01.6.5.1-167_SPU-15-M2-3_SIGNEuropeAustraliaEMEA_USASPDRRTGB_HWp2b_Service1FF_fastboot

SPDREM_U_01.6.7.2-180_SPU-19-TA-11.6_SIGNEuropeAustraliaEMEA_USASPDRICSRTCEE_HWp2b_Service1FF_fastboot.xml

SPDREM_U_01.6.7.2-180_SPU-19-TA-11.6_SIGNEuropeAustraliaEMEA_USASPDRICSRTGB_HWp2b_Service1FF_fastboot.xml

SPYDERIRD_U.01.26.0_SPD-IRD-21_SIGN_ASIA_RETAIL_HKTW.xml

SPYDERIRD_U.01.26.0_SPD-IRD-21_SIGN_MEA_RETAIL.xml

The only thing I am quite sure about is that it is not LATAM.

* I tried manually flashing the various image files with moto-fastboot, fastboot, and eprj-mfastboot, both the Windows and the Linux versions, with pretty much always the same result: it would flash some files (e.g. ebr, mbr, devtree), but not what I think are the crucial ones: boot, system, also logo.bin. As there are so many possible combinations, I have not tried every file from every firmware I downloaded with every possible program, but as far as I can tell, the results were the same. I did get some error messages about signing (indicating wrong region) sometimes, but most of the time it just hangs forever while supposedly transferring the files.

* I also tried the DroidRAZRUtility, both 1.51 and 1.6, which both invariably fail at the first step of flashing the "allow-mbmloader-flashing-mbm.bin" file on there.

So, I am out of ideas now. Please, someone tell me I have overlooked something obvious. Also, please tell me I haven't bricked the thing for good.

Is there not a way to write something new into it's memory on an even more basic level (I am thinking Linux' dd here), or to read out which region it is currently locked to? I repeat, all I get is the Fastboot screen, I can get into the Fastboot menu, but none of the options gets me anywhere else, (stock) recovery does not work... My last idea is that it might still be a power issue despite the "factory cable", and to try and crack it open and power it at the battery contacts for flashing - but the fact that some flashing works, and the other files don't fail because it goes dead, but because it rejects them, suggests to me it is not a power problem.

Any suggestions appreciated, thanks!
