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.

The issue is my CDMA data is not working after upgrade to kitkat. I m from India and using Reliance CDMA sim. Before update, everything was working perfect. But now only data(EVDO or 1x) is not working. GSM data(3G & 2G) is working.
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.

Hello,
I want to relock the bootloader and go back to stock.
I tried flashing stock firmware using fastboot.
fastboot oem lock begin
flashed stock firmware
fastboot oem lock
But Bootloader is still unlocked.
I got message as first flash full stock system. Something like that. Don't remember as I tried this a week ago.
Any help will be highly appreciated.
Thank you in advance.
Edit : I also tried the Windows tool provided by one of the members but it failed too.
I used the same to unlock in the first place.
I think it depends on what you want to achive. While you might be able to re-lock the bootloader (which means it can't be flashed without being unlocked again), you will never ever get rid of the unlock message again. This - to my understanding - is an efuse which is permanently set. If you want to remove the unlocked bootloader boot message, I'd stay unlocked and would just flash a different boot logo (logo.bin) where the unlocked gfx are replaced with the standard gfx thus showing the standard boot logo.
I would like to relock the bootloader altogether.
I don't think you can. You can lock it but you can't remove the warning that it has been tampered with.
I don't care about the warning.
I just want to re-lock it.
Flashing the Official firmware for my Country - India did the job.
Last time I tried with firmware for ASIA.
I don't see any reason for that to fail but you never know.
Thanks for replying.
hey can you give me the link for that rom im also using the indian version but unable to lock the bootloader
[No s-off required] T-Mobile and MetroPCS variants don't ask for an unlock code when foreign SIM card is inserted. It requires to contact carrier to allow SIM unlocking and this is done through their own app "device unlock" and no code is inserted. To get authorization to unlock it, could be difficult contact carrier because sometimes you're not client of T-Mobile or MetroPCS or you're not in the US.
But you can bypass app and unlock it with an unlock code (easy, cheap and fast to obtain it) if you follow these steps (will wipe all your data):
1. Unlock bootloader (htcdev.com)
2. Flash twrp recovery (https://forum.xda-developers.com/desire-530/development/recovery-twrp-3-0-2-0-t3582805)
3. Download the unlocked/developer RUU for HTC Desire 530 (http://dl3.htc.com/application/RUU_A16_UL_M60_DESIRE_SENSE70GP_TMUS_NA_Gen_Unlock_1.01.617.27.exe)
4. Download RUU Decrypt Tool (https://forum.xda-developers.com/chef-central/android/tool-universal-htc-ruu-rom-decryption-t3382928) and extract system.img from downloaded RUU (step 3).
5. Copy system.img to the root directory of the phone and flash it with twrp recovery.
6. Once system.img was flashed, just restart phone, insert a non-Tmobile/MetroPCS sim card and phone will ask to insert the unlock code. Unlock code is easy to obtain in ebay or another pages for less than $3, just ask for a generic htc unlock code. Insert the unlock code and restart it.
7. You can download the T-Mobile or MetroPCS RUU and flash it again to the original carrier. It's not mandatory to relock bootloader to flash the original RUU.

Use fastboot to flash the system.img, Flashing with TWRP is buggy.
For guys who own xtc2 clip , do S-OFF and unlock on special unlock tab to unlock without credits.
Hello friends,
Need help here. I am willing to buy T-mobile variant of V20. Its on firmware H91010t march security update. I searched all over the forum for the last one hour but could not get the clear cut answer. If this device can be bootloader unlocked. Can I downgrade to any unlockable older version and unlock the bootloader or now its not possible? Any help will be greatly appreciated. Thanks.
Yeah the H918 is bootloader unlockable, however you need to use a root exploit in order to utilize it as there are limited fastboot commands available.
If you're not familiar with Linux though you should wait for the automated version of the exploit to be released so you can make sure you don't mess anything up.

Thanks bro. Please clarify one more thing. It says we must have bootloader unlocked before proceeding this process. So T-mobile varient comes boot loader unlocked?

It comes locked, but it can still (and must) use fastboot oem unlock to unlock the bootloader (the reason exploits are needed is because the h918 fastboot can not flash anything). As usual fastboot oem unlock will factory reset the device so make backups.
As far as rolling back, don't rollback too far or youll brick: just roll back to the version explictly named in the lafsploit guide.
you must enable developer mode and turn on usb debugging <~~~~ in about phone section find the Build number and click it 6-7 times to enable the developer mode option. after that follow the fastboot oem unlocked commands, after unlocking the bootloader. if you want to roll back on firmware DO NOT go before H91810p or you will brick your phone, so your options are h91810p ,q ,r,s, or t which your on. follow the lglaf h918 information in the xda forums. go into search and type lglaf h918. hope this helps
