Please help me.. Thanks in advance...
Wouldn't recommend you try it on a locked bootloader.
Those that are unlocked shouldn't have any issues.
Technically, with a locked bootloader, if Fastboot will allow you to downgrade, then it should be possible.
You'd have to boot into Fastboot, then run the command:
fastboot flash system system.img
Where system.img is the 4.1.2 image file extracted from the fxz file. If it won't let you do this, then downgrade isn't possible. It will likely say failed flash and you'll have to flash something to kick the phone out of fastboot like logo.img.
You could also try RSDLite and try to flash the 4.1.2 fxz, but I doubt that will work because bootloader and such are not downgradeable and it will likely fail.

You can get them here:

You can extract the original system.img from the archive as well as logo.img in case the phone doesn't allow you to flash system.img, you can use logo.img to kick the phone out of Fastboot. You will need to install Motorola ADB drivers on your computer in advance, and also need a fastboot.exe file which I think you can find via Google, but if you have ever rooted your phone in the past, usually that also came with fastboot.
Anyway, get into fastboot mode by turning off the phone, then holding down all 3 buttons. Use vol- to select Fastboot and vol+ to choose it. Phone should boot into fastboot.
Connect to PC and issue command:
fastboot flash system system.img
If it works, the phone should be downgraded. If it says flash failed, then downgrade isn't possible. In that case, if the phone is stuck in fastboot mode and can't be rebooted, issue this command to get out of fastboot.
fastboot flash logo logo.img
That should let it reboot as normal.
I actually doubt it's possible to downgrade, but I haven't tried it myself so I can't say for sure.

Thank u so much my friend, I need to clear that I m using this phone in India with Reliance CDMA network. If downgrade will succeed then will it in verizon locked condition or it will remain unlocked for global use? Also I need to add that I have never unlocked my bootloader or rooted my phone.

I think it would stay unlocked since you wouldn't be reflashing the radio.
It is easy enough to re-unlock if that should get reversed, however.
Ah, nevermind. Don't bother to try it. Even if you could succeed, you'd end up with black screen after the logo. The newer bootloaders will not allow Jellybean to boot. There is no way to downgrade. KitKat is a one way road with a locked BL. Sorry!

Sorry for the bad news. I'm in the same boat now too. Thought I would experiment with ways to preserve root, and long story short, now I'm stuck on an unrooted phone on stock KK with locked BL.
Why do you want to downgrade? If it's to be rooted, sorry, no solution for that. If there is some other issue, maybe there is a solution for that specific issue.

Please help if u have any solution for this issue.

Sorry, with locked BL, you can't flash modified system.img or older system.img. I tried it just to make sure, and the phone wouldn't allow it.

Good news is that major developments happened a month ago. :good:
You can now root AND unlock bootloader on KitKat. I think you can find the info you need in this thread:
http://forum.xda-developers.com/showthread.php?t=2783806
Once you have bootloader unlocked, you can downgrade back to JB. I have tried it and can confirm it works.
Good luck!

You just run it and let it do its thing. Your phone should be rooted once it has rebooted. You can verify with any rootchecker app.
Then install and run Motopocalypse.apk to unlock your bootloader.
You can the use RSDLite to flash back to JellyBean using the JB fxz file. You will need to edit the xml file in the fxz file, removing the lines with gpt.bin and tz.mbn.

Hi Everyone,
I own Motorola Electrify M (XT901) CDMA handset.
I had unlocked the bootloader, installed recovery-clockwork-touch-6.0.4.4-xt907.img and was running CM11 with jellybean bootloader.
I thought of flashing my mobile with stock rom of XT907. So downloaded "VZW_XT907_4.4.2-KDA20.62-10.1_CFC_1FF.xml.zip". After extracting the contents. I executed the following commands to flash the mobile.
fastboot flash partition gpt.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash sbl2 sbl2.mbn
fastboot flash sbl3 sbl3.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash system system.img
fastboot erase tombstones
fastboot erase cache
fastboot erase userdata
Now the mobile is not booting. Please help me to unbrick my mobile.
Regards,
Ramakrishna.

Thanks friend for the quick reply. I realized my mistake. But its too late. Now the mobile is not detected by my pc. Neither I'm unable to flash it using RSD lite nor run commands as it not detected by adb also. When I plugin by device to PC I get message drivers not installed and its asking for drivers of "qhsusb_dload". Currently I'm using windows 7 OS.
Please guide me and help me.

You need to boot into fastboot, before plugging the phone into the computer.

The sentences "fastboot flash partition gpt.bin" and "fastboot flash tz tz.mbn" has set off the alarm. You have now hardbricked it because of the bootloader signature NOT belonging to the XT901. Bootloader signatures on both gpt.bin and tz.mbn are different for each models. You might get away with flashing the unofficial XT907 kernel on XT901, although I doubt it due to bootloader differences.
But you may get pretty lucky enough to flash back to the XT901 bootloader. Hope you have enough juice in the battery, otherwise you will have to either make or buy a Motorola factory jig USB cable to force the phone to boot without the battery if s*** hits the fan.
Root..

System version? Not android version
Full kernel version?
Sent from my XT907 using Tapatalk
The KitKat update was released last month, so most likely the kernel is "rather new".
It that's the case, Towelroot might be locked out, but it's still possible to unlock the bootloader via Motorola (to install a custom recovery etc.).

Hi slgdad,
I have successfully rooted my updated XT901 with 4.4.2 stock rom.
Pre-requisites
1. XT901 bootloader should be unlocked.
The steps I followed
1. Kept the mobile in fastboot mode.
2. Flashed recovery with "ClockWorkMod Recovery v6.0.4.9 for DROID RAZR HD/M" [Link to download]
fastboot flash recovery CWM6049-RAZR-HD_M-KITKAT.img
3. Loaded to recovery, install "update supersu v2.46.zip" by chainfire. I'm not sure if I can provide the link for external sites. Better search on google for the zip file.
And XT901 is rooted. I hope this helps you. Feel free to ask questions.
Note: I have not made any changes to img file or zip file. I have used as is. They are works of their respective owners. I'm just a pointer, indicating the files I used to root XT901. Please do share this post if required.
Regards,
v2k100
Thanks! I will try it! But i still have a locked boot loader. I can't find away to get it unlocked.?

I believe at this joint you need to tree flash the .15 stock ROM.
And you cannot down grade. There is currently no way to unlock the .15 boot loader. Except by paying a person to do it for you.
