Hi,
My search skills are very bad so pardon me if this has been asked too many times.
I've read somewhere that downgrading is possible by manual method without flashing the gpt and motoboot file.
Once downgrade is done. is it possible to install a custom kitkat rom afterwards?
You should be fine. Flashing gpt.bin file is necessary when coming from a GPE to non-GPE ROM. GPE and non-GPE do not use the same file format for user data.

I have a moto g global version xt1032.
Thanks. I actually installed lost101's optimized 5.02 which i did not think was a gpe version. however, I downgraded to 4.4.4 using a script to 4.4.4 gpe. I am getting ota for 5.0.1. If I do want to update to it sometime, will it work?
If you are on stock 4.4.4 with stock recovery and unrooted, OTA should work.

Here's the scenario:
I converted Moto G XT1033 4.4.4 to GPE 4.4.2
Then upgraded to GPE 4.4.4 and GPE 5.0.1, both by OTA
GPE 5.0.1 OTA ended up in softbrick
So now I cannot repeat the process beacause of the new bootloader, GPE 5.0.1 OTA brought with itself. And that bootloader would cause a hardbrick if I tried GPE 4.4.4 OTA on the device now
Questions: (No question is related to the other)
Would I be able to install Stock Lollipop OTA when I get one on 'Stock rom'? (I can revert to Stock 4.4.4) Would Stock Lollipop OTA mess up with the current bootloader, GPE Lollipop OTA has installed?
Is there any way I could flash Lollipop Stock image later, when it's available?
What can I do to set things right with the 'bootloader messup' that's caused right now?
Thanks, in advance!

You are another who has made a stupid mistake, you should HAVE READ MY THREAD!
You need to wait untill the Lollipop Factory images are published, then we can get a blankflasher and restore your bootloader.
Once your bootloader is working again, you can flash Lollipop without problems.
You need to wait 1 or 2 months.

Nope. I did read your thread after softbrick. And that's why I didn't install any OTA's after v5's.
I flashed 4.4.4. It's not an OTA!
I'm currently running 4.4.4 on 5.x bootloader.
Now what I'm asking is,
Would I be able to install 5.x OTA when I get it?
Before the factory image and all that thing.
PS: 5.x hasn't arrived for general public in INDIA yet. What I was trying was Brazil OTA.
Hi, i've been reading a lot of posts explaining how to do "GPE LP to KK", and other things, but i want to know if i can flash the BR 5.0.2 firmware image directly above my 5.0.1 GPE without any problems. Thanks in advance
If you manually flash the stock BR 5.02 to each partition using fastboot commands, you should be fine. Every file will flash except for the motoboot file. I say this because I was able to flash stock Telus 4.4.4 on an xt1032 that I converted to the GPE edition.
So doesn't matter if motoboot refuse to flash, because GPE and Stock LP have the same included, right?
For me, stock 4.4.4 and stock 5.02 both worked on my xt1032 with bootloader 41.18.
Even if you tried to flash an older bootloader, it would fail the validation check.
Ok finally i managed to downgrade to EU retail 4.4.4 and then OTA to 5.0.2. All the process was great. Thank you for your help [emoji4]
I have a XT1032. In the past it ran Motorola (not GPE or anything) Kitkat 4.4.2. Three months ago I upgraded it to GPE 5.0.1, because of my stupidity for not realizing what "GPE" meant. I hate this GPE and have already done with it. Could you guys, please, show me a way to go back to Motorola firmware Kitkat 4.4.2. I don't want anything relating to GPE anymore. :crying::crying::crying:
My XT1032 is en-us version, FYI.
Download the stock 4.4.4 ROM for your phone from here: http://www.filefactory.com/folder/c6cdedc45a775d27/?sort=filename&order=ASC&show=100&page=1
Flash it manually using fastboot commands. Do no flash anything below 4.4.4 as doing so may brick your phone.

Thank you. Instead of downgrading, can I upgrade GPE 5.0.1 to Motorola 5.0.2, then wait for Motorola 5.1 OTA update? Is there any risk to switch between GPE and non-GPE (Motorola)?
The partition layouts are slightly different and I believe the data partition on gpe (ext4) and stock (f2fs) are not the same.

audit13, I really don't understand all the commands I need to type when using mfastboot. When upgrading my phone to GPE, I followed this post (http://forum.xda-developers.com/moto-g/general/gpe-ota-lrx21z-5-0-1-xt1033-xt1032-t2969847). Is there any difference? Could you show me some links to learn about how to use those commands? I don't know what I should type, what I should do step-by-step. Thank you.
This is a good guide: http://forum.xda-developers.com/showthread.php?t=2542219

Flash a gpt.bin file of some other firmware and then flash a ROM or flash GPE 4.4.4 firmware and then continue.

Yes you can directly downgrade. Avoid flashing motoboot.IMG since as of now there are changes of bricking. You'll have screen flicker only on GPE 4.4.4. After flashing thee screen will not flicker any more.

what to flash to avoid flickering
What should i be carefull about when moving through firmware versions?
For ex: from 5.1.2 Moto to 4.4.4 GPE, or 4.4.4 Moto to 4.4.4 GPE.
As far as i know, when switching from LP to KK you cant downgrade BL (flash motoboot.img), in my case i have the lastest one already.
And also i know that Moto and GPE have different partition tables, so i dont know if i should flash gpt.bin or not in this case. Furthermore id like to know if gpt.bin should be flashed while downgrading from 5.1.2 Moto to 4.4.4 Moto.
All information is apreciated, i really want to learn this. Greetings!
Do not touch the Bootloader unless you have a really good reason.
You can easily change between ROMs using Custom Recovery. You do not need to think about partition tables, only how /data (userdata) is formmated. GPE uses EXT4, all other Stock Motorola Firmware uses F2FS. Even then, GPE can be used with F2FS if you flash a different Kernel. For example, you can Boot GPE 4.4.4 with a Stock Motorola non-GPE 4.4.4 Kernel.
