[Motorola Droid RAZR] hochsaler:
screwed up device

Dear all,

I have a problem with my device and hope somebody can help me with that.

First I need to explain a little... I bought a Japanese IS12M (yes, I know, it's CDMA Spyder, XT909 ?), but still I post here because now it is XT910. :D

I was always unhappy with the original Japanese firmware from kiddi/au because it didn't seem to read the SIM card at all. I rooted the phone successfully, installed BMM and recently safestrap (rev. 3.65), made a backup of the stock ROM with safestrap and restored it successfully to slot 1. After some internet research I found out that this device is technically almost identical with XT912 (from Verizon in the US, this device does just not have the LTE support). For this reason I installed some ROMs for XT912 successfully, e. g. CM10.2 in slot 1 and aviator gummy 2.1 in slot 2. They seemed to work quite well with this device.

Since I have the safestrap backup of the stock ROM (not really original, rooted and some other modifications) I became keen and tried to install other ROMs on stock. And there the problem begun. It didn't work and I was only able to boot the phone in fastboot. So my backuped ROM didn't help me.

I opened RSD Lite and tried to flash other ROMs. Finally I was successful with a ROM which I found in a Chinese forum using google translator. It seems to be an earlier revision of the ROM from post #1 here. The phone booted and everything seems to work well. Now it reports to be XT910 and the about phone page shows only the following differences to post #1:

System revision: 672.300.400.XT910.ChinaRetail.en.CN

Build number: 672_GC-400

Baseband: N_05.11.01P

The main difference is the baseband (of course, hardware is still CDMA) and probably some Chinese developers created this ROM specially for this device.

After reading this thread I wanted to update to the ROM from post #1 because the current revision has many restrictions:

- I am not able to root it, all methods described here failed

- I don't know how to use the recovery which came with the ROM, it seems to be some standard recovery, no menu, no selection etc.

- gapps are missing in this ROM, installing packages using adb is quite ridiculous and many will not work since not rooted, e. g. Titanium Backup

But it doesn't work somehow, although it is only a minor change in revisions:

1) when I follow the instructions in post #1 the phone will not boot anymore (although flashing in RSD Lite is successful)

a. since it probably has a different baseband I excluded radio.img from flashing - but still no success

b. I tried to flash recovery, boot.img, mbr and ebr and so on because I hoped I could boot into BMM or recovery - but also no success

Finally I managed to flash only system.img from the ROM in post #1. The phone boots and works pretty well. Revisions are the same as in post #1 except baseband of course:

System revision: 672.300.404.XT910.ChinaRetail.en.CN

Build number: 672_GC-404

Baseband: N_05.11.01P

But I expected this revision to be rooted and to have BMM. But I still have the same apps from the original installed Chinese ROM which means no gapps, no BMM, no root... :(

I don't want to do something special, but I would like to have at least gapps (I tried to install some apk via adb, but play store does still not work).

I wonder, if somebody could help me. I can think of several solutions:

- providing original Japanese IS12M flash file from kiddi/au (could not find it, all links are broken)

- give me a working solution to root the phone and to install other apps

- or is there a way to convert safestrap backup to flash it with RSD Lite?

All help is welcome, thank you.
