GPE OTA (LRX21Z) 5.0.1 on XT1033/XT1032 topic

06:29






Okay, so there has been a lot of confusion an ambiguity on how to successfully install the GPE lollipop update on the XT1033. The reason i am starting this guide is because I faced a lot of trouble myself trying to get this update and had to scavenge through multiple threads to get stuff working. I had flashed the update on my Moto G XT1033 converted to GPE using the mixed firmware by @deej_roamer [using this tutorial], OTAed to 4.4.4 and flashed the OTA manually using ADB. I was stuck at the bootlogo following this. This was because of the firmware being modified this interfering with the OTA. Since i was now stuck with the new 41.18 bootloader and the partition table (gpt.bin) of the OTA, i could not flash the XT1033 firmware. So this is what I did:

THE FOLLOWING PROCEDURE CAN BE USED BY ANYONE WHO WISHES TO GET THE OTA WHICH IS BEING TALKED ABOUT IRRESPECTIVE OF THEIR MODEL:

1) Download the 4.4.4 GPE XT1032 FIRMWARE from [here]
Download mfastbootv2 from [here]
Download minimal sdk from [here]
Download and install adb drivers from [here]
Download Motorola drivers from [here]
Reboot system after installing drivers.
Download OTA update from [here]
Download your respective base firmware and just copy NON-HLOS.bin and fsg.mbn to the folder where you have extracted the sdk, mfastboot and the 4.4.4 GPE firmware. Copy the OTA zip to the same folder.

2) Boot into fastboot (POWER+VOLUME DOWN) and connect phone to PC

2.1) If you have already made a failed attempt to OTA, then flash it using the following commands to flash the 4.4.4 GPE firmware via CMD (make sure the directory of cmd is the same as that of the folder where all the files have been extracted) else go to 2.2)

Code:


mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img_sparsechunk.0
mfastboot flash system system.img_sparsechunk.1
mfastboot flash system system.img_sparsechunk.2
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
mfastboot reboot


You will not get network now but do not flash the modems of the firmware you use now because you will get a status 7 error when flashing the OTA. You will now be dumped at the welcome screen. Do not enter any details, just power off and boot into recovery via fastboot.

2.2) For those who haven't attempted the OTA, use the following commands to flash the 4.4.4 GPE firmware via CMD (make sure the directory of cmd is the same as that of the folder where all the files have been extracted)

Code:


mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img_sparsechunk0
mfastboot flash system system.img_sparsechunk1
mfastboot flash system system.img_sparsechunk2
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
mfastboot reboot


You will not get network now but do not flash the modems of the firmware you use now because you will get a status 7 error when flashing the OTA. You will now be dumped at the welcome screen. Do not enter any details, just power off and boot into recovery via fastboot.

3) Now we shall flash the OTA. Choose apply update from adb in the recovery and typed the following command

Code:


adb sideload <name of OTA archive>.zip

4) Once it has finished, select reboot system now from the recovery.

5) You will be put at the welcome screen after a few minutes. Power off, boot into fastboot and flash the files needed to get network using the following command

Code:


mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot reboot


You shall now be running 5.0.1 GPE !

I HAVE TESTED THIS FULL PROCEDURE MYSELF. BUT I SHALL NOT BE HELD RESPONSIBLE FOR ANY PROBLEMS THAT MIGHT OCCUR BY USING THIS PROCEDURE, THOUGH I SHALL TRY MY BEST TO SOLVE THEM IF YOU FACE ANY.
