Simply install any LP ROM with specified instructions. Or if you want to restore pure stock, Relock bootloader and Install the IMG file.

You can use the modded stock rom and flash it from TWRP --------> Modded Lollipop 40.60 Stock Rom (Google Drive Link)
and flash the stock kernel through fastboot before you update to build 40.87 --------> Stock Kernel (note - this will remove the TWRP recoveries, After update you can flash TWRP recoveries back)
Otherwise, you can use this tutorial If you doesn't want to download the files. ( I recommend you to just download the flashable stock rom )
Or you can download and flash any custom stock rom (I prefer cleanstock rom, not to much bloatware)
Good luck

What commands did you used to flash stock? Did you flashed bootloader?

try another rom and contact me bhai my e-mail id Moderator Edit: Nope, XDA is where we share, NOT your personal email and the likely consequences of that.

Happened to me when I rooted my XT-1643 on MM, flashing custom kernel fixed my issue

Possible Stock ROM for XT1643: https://firmware.center/firmware/Mo...24.139-13.1_cid50_subsidy-DEFAULT_CFC.xml.zip
1. Extract that and reboot to bootloader
2. Make sure you have system wide adb/fastboot installed or have adb/fastboot somewhere.
3. From cmd/powershell, mfastboot flash modem NON-HLOS.bin
4. mfastboot erase modemst1
5. mfastboot erase modemst2
6. Reboot
If that doesn't work, try flashing the whole Stock image using Motorola RSDLite.
Good luck!

stock rom .zip file for sideload through recovery? XT1625 Prime Edition

there's no a way to install stock rom for Moto G4 16 gb prime Edition through sideload in recovery mode (adb)?
i had installed nougat update from india and now i'm stuck in recovery mode. So.. i can't send my phone right now to US and i trying to find a way to recover my phone from this
I can't do a downgrade to MM because of nougat.
So, give me some ideas

Somebody could make a backup of their nougat's rom and upload it?

I am in the same boat (mostly because I am a moron, and thought I had unlocked my bootloader when I hadn't).
If anyone sees the amazon prime xt1625 nougat floating around you will be my hero.

You need a TWRP backup of the nougat ROM?

Try to find a thread with the stock AMZ firmware, then install that. Updates will have to be re-installed, but it should unbrick your moto

Bootloader and modem question

How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?

I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.
