Firmware and modems

OK, if you are here you have 3 possibles scenarios.

1. You are on 4.4.4 (really?) and want to update to 5.1 official.

2. You are on a converted version of some variant, like XT1097, 1092, etc using this post early this year and you want to update to 5.1 OFFICIAL, because even you are receiving the OTA you are not able to install it for some error showing on the stock recovery.

3. You are on 5.0.x of some carrier (like me), your BL is unlocked and want to convert to the pure edition 5.1 official.

IMPORTANT. From 5.1 update, the modems included on the update are FULLY compatible with all models, XT1097, 1092 and 1093 and all carriers ,so, you don't have to worry about losing IMEI, signal or data.

SCENARIO 1, 2 and 3.

Download the ENTIRE SYSTEM of the 5.1 of this link

Extract all the files on the carpet where the ADB and FASTBOOT files are.

After that you will only have to put your phone on BOOTLOADER MODE, connect it to your PC and type this to check if your computer recognices your phone: fastboot devices and if you see the serial number of your phone you are ready to go.

By now you are going to flash all the files you need to be on 5.1 pure edition, you will loose all your partitions and root and all your mods.

NOTE. IF YOU HAVE EXPERIENCE FLASHING FILES AND WANT TO KEEP SOME PARTITIONS PLEASE REFER BELOW THIS CODE; IF YOU DONT HAVE IDEA WHAT I AM TALKING ABOUT FLASH THIS CODE

fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.img
fastboot reboot-bootloader
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot flash modem NON-HLOS.bin
fastboot erase userdata (optional)
fastboot erase cache (optional)
fastboot reboot

Let me explain the files

fastboot flash partition gpt.bin - Will flash the new partition of the system and data to receive the new update, is not a mandatory flash, like some people are reporting, you just can skip this if you want, but I dont recommend if you are on 5.0.x

fastboot flash motoboot motoboot.img - The BL version 60.16, you can skip this for sure if you are on 5.0 and 4.4.4, but if you are on 5.0.x is a must-flash.

fastboot reboot-bootloader - reboot the bootloader

fastboot flash logo logo.bin - the boot logo, is optional in any case

fastboot flash boot boot.img - kernel, you have to flash it

fastboot flash recovery recovery.img - Stock recovery, you can skip it to keep the TWRP

fastboot flash system system.img - full 5.1 system, must flash

fastboot erase modemst1 - erase old baseband

fastboot erase modemst2- erase old baseband

fastboot flash fsg fsg.mbn - flash the new baseband, must flash

fastboot flash modem NON-HLOS.bin - flash the new baseband, must flash

fastboot erase userdata - optional for all users, but in order to avoid problems, must do it.

fastboot erase cache- optional for all users, but in order to avoid problems, must do it.

fastboot reboot - say no more.

After that your phone is now

Enjoy!!!

The whole pack in ZIP, just flash it via TWRP and the modems only, just in case you forgot to backup.
