Hello.
To cut a long story short: I used to have my RAZR XT910 (with deleted and lost CID) running on a Chinese kernel and a modified Chinese ROM that was working like a charm. Unfortunately I messed things up with BMM (my fault!) and to un-brick it fastly I used a method that fixed the problem but that got me on
ROM: 982.124.14.XT910.Retail.en.EU
Kernel: 3.0.8-g7198280 [email protected] #1 SMP PREEMPT
As explained it appears that:
"With that unbrick method, you have flashed EMEA 4.1.2 OTA which flashes cdt.bin secure version 7. Once the cdt.bin is upgraded you will not be able to flash partitions signed with lower secure version. In your case, china system,boot,recovery have version 5 but your device is flashed to version 7. There is no known way to bypass it. You are stuck with EMEA 4.1.2 custom roms or CM variants, sorry."
Isn't there any "hard-core" method to work around this? No leak or whatever?
Thanks a lot!

Hi All,
After installing the zip 720p+panorama on my Defy Plus 2.3.6
System version:
45.0.2310 nonefigs retail EU
Build number:
4.5.1-134_DFP231
it becomes:
2.3.4
45.0.74.MB526.retail.en.DE
4.5.1-134_DFP-74
Is it normal?
P.S. The phone with the mod is working just fine.
This happens with my defy+ too!. i have 2.3.5 but i didint know what was causing it. mine goes form def-50 tp def-74
From what I know/understand it's impossible to downgrade from DF-231 (exept from flashing the phone), so the info that the phone shows is fake somehow. May be the mod overwrites some files/memory portion wich has the firmware id... I don't know just supposing. May be some one more competent can say.
Hey guys, so I got 2 problems atm...
First, I bought unlock code from cellunlocker, and put it in, it unlocked my phone but it can't find the tmoible service. (I have a tmobile microsim in it) Any help?
Second, Im gonna flash FTS 1.2, it requires my system ver to be 672.180.33, if not to flash this. My current system is:
System version: 672.180.352.XT910.Rogers.en.CA
Android version: 4.0.4
Kernel: 3.0.8
Can I flash the eternityproject rom via rsd without brick?
Thanks!
Anyone?
Hello,
I am quite new to the forum although I have some experience in modding my mobile, so I hope I am posting in the right section.
I summerize here my problem.
I had ICS on my XT910, then I installed BMM on my XT910 and a ROM named "Muscle China" that brought along a JB China kernel (which allows flawless phone call recording), a new radio and very interesting features with Andoird 4.1.2 version.
While updating an installation on Slot2 I deleted the "system" partition on Slot1 by mistake.
I was in a hurry and I needed to have my phone functioning ASAP. So I used a method to "unbrick" the RAZR that worked but installed the stock 982.124.14.XT910.Retail.en.EU.
Now I learnt that there is no way back, i.e. that this JB EU is locked and does not allow you to install other kernels.
In fact when I tried to reinstall the JB China kernel and I enter in AP Fastboot, I connect the RAZR to the PC and I input:
fastboot flash boot boot.img
what I get is:
writing 'boot'...
(bootloader) Preflash validation failure
FAILED (remote
finished. total time: 0.613s
My system info are:
System version: 982.124.14.XT910.Retail.en.EU
Base band: U_04.10.00R
Webtop version: wt-3.0.0
Kernel: 3.0.8-g7198280 [email protected] #1 SMP PREEMPT Thu Feb 28 01:30:46 CST 2013
APFlex: GAS_EMEA_USASPDRJBRTGB_P011 GAS_EMEA_USASPDRJBRTGB_A012
Build: 9.8.2O-124_SPUEM-14
Can someone advise me something to do or give a help?
Thanks!
You may want to do a system wipe and flash fresh.
RAZR Maxx running Premium
With that unbrick method, you have flashed EMEA 4.1.2 OTA which flashes cdt.bin secure version 7. Once the cdt.bin is upgraded you will not be able to flash partitions signed with lower secure version. In your case, china system,boot,recovery have version 5 but your device is flashed to version 7. There is no known way to bypass it. You are stuck with EMEA 4.1.2 custom roms or CM variants, sorry.
an hyperlink to Muscle China rom would be nice.
hello
sorry for the belated reply to your request:
the hyperlink would be to an Italian forum where a great Italian guy developed a JB China based (4.1.2) version.
It is in Italian only, but I can try to put you in touch

Hello!
I had XT910 with ICS 4.0.4 673.94.328.XT910.AsiaRetail.en.03
Flashed successfully with RSD Lite to "O2 UK"
9.8.2O-124_SPUEM-14_S7_USASPDRICS01O2UKE1007.0R_USASPDRJBO2GB_P013_A012_p2b_S1FF_fb.xml.zip
then to "Retail British": 9.8.2O_124_SPUEM_14_S7_USASPDRICS01RUKE1007.0R_USASPDRJBRTGB_P011_b57374ab5a_p2b_S1FF_fb_CFC.xml.zip
This was a mistake, because it has no support for ME Hebrew/Arabic languages.
Since there's still no EMEA JB ROM, I wanted to flash back to Asian or ME ICS. But RSD Lite shows an error from device on the very first steps
I found many claims that the downgrade JB->ICS not possible for XT910 because of locked bootloader. But all of them were talking or explicitly about OTA JB , or didn't mention the way at all.
So two questions - if I used only fastboot ROMs - can I still somehow downgrade to ICS?
and if NOT: which Retail JB ROM has support for ME languages ?
Thanks
The answer is NO. You cannot downgrade. I'm not sure about ME lang support.

Can someone tell how to upgrade from 4.1.2 to 4.2.2 custom roms for XT910?
I forgot the steps to upgrade. Currently I can use BP tools only to boot up and it shows CustomerID error (I lost backup file)
Current System version is...
982.124.14.XT910.Retail.en.EU
Webtop Version : wt-3.0.3
Build Number : 9.8.20-124_SPUEM-14
Already rooted.
Thanks a lot.
To install 4.2.2 version you need to use Boot Menu Manager or Safestrap.
