I recently converted my xt1033 to gpe on 4.4.2 and then did an OTA update of 4.4.4. I am recently downloading 5.0.1 OTA and now question is that if I did that OTA upgrade, will I be able to revert back to the stock xt1033 ROM or stock gpe or even any custom Roms? I am reading these forums that if I do straight OTA update to 5.0.1 of a gpe converted device, I would brick my device so the correct way to update would be to download and sideload the OTA zip.
I am really confused right now. Please someone reply. Thanks in advance.

Hello, everyone!
I've been using an XT1032 for a long time now and flashed a lot of different ROMs and kernels on it. At some point this year, I decided the best combination was GPE KitKat with XPosed Framework. It worked great. Now, before Lollipop started to rollout OTA, I decided to give CM12 a shot and flashed various ROMs. As they are really buggy, I want to go back to KitKat.
But, I've seen that going to Lollipop can flash a new bootloader that can cause problems if you want to go back to KitKat. As far as I understand, this only happens if you update to Lollipop through OTA (or through fastboot one of the ROMs extracted from official Lollipop releases) and not when flashing the CM12 ROMs, but I really want to be sure:
Can I safely flash a KitKat ROM (like CM11)?
For help, thanks a lot!

If you converted your phone to Brazilian firmware and side-loaded 5.0 OTA then your boot-loader was upgraded and will cause problems downgrading to 4.4.4 Kitkat. It's the same if you converted your phone to GPE and side-loaded the 5.0.1 firmware; boot-loader was upgraded. There are a lot of threads of people bricking their phones when they decided to downgraded, so if you did any of the following stay on Lollipop. If you had Kitkat and just flashed CM12 and never flashed Official Lollipop then you are safe since the boot-loader was not upgraded. Just to feel safe boot into Fastboot Mode and make sure your boot-loader is 41.13. If it's different don't flash stock KitKat ROM.

I just flashed CM12 over Kitkat without every flashing official Lollipop. I did what you suggested and my Bootloader is still 41.13, so everything is OK. Thanks a lot!
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 have two Moto G 2013 XT1033 Dual Sim and for both of them - i dont care about losing data and reinstalling - I want to get to a 100% STOCK 5.0.2 state. Dont need root or customer boot.
No 1) Upgraded from 5.0.1 Soak Test Brazil - 220.21.25.falcon_umtsds.Brasil.en.BR, no root, stock bootloader > to 5.0.2 using the incremental ZIP that was provided in some of the recent posts here.
Will I be getting automatic OTAs from now on? Is this equivalent to stock flashing 4.4.4. an then OTAing up to 5.0.2?
No 2) Optimized non-stock firmware 4.4.4, with bloatware reduced etc. dont remember who made the ROM - also Retail, but bootloader unlocked and have root
What is the best approach to this one to a stock 5.0.2, no-root, locked bootloader, is there just a single binary stock 5.0.2 file that I can flash?
Should I downgrade both to 4.4.4 Stock and then upgrade via OTA?
I know for (1) there exists an incremental update, how safe is this?
For (2) the OTA arrived, but as its an optimized ROM the update does not work.
I know all the information is somewhere here, I just was confused what path is safe and if its not possible to simply flash some binary recovery (ideally already to 5.0.2)
I think you should back to 4.4.4 than upgrade to 5.0.2
For back to stock 4.4.4 you can use this

One of my malware protection tools rejected the untouched brazil 4.4.4 download. Where do I find the original files and confirmed hashes?
I have converted my moto g to gpe. I've literally love the speed of 5.1 and can't go back.. Since all ROMs for 5.1 are buggy(at least for me) I've decided to try official ota gpe. I know I should revert back to stock kitkat gpe which is easy but I'm afraid the ota update for lollipop might brick my device since it's not gpe and that it already has lollipop bootloader from dual sim moto g. Is it possible to do this without running into fatal issues ?
It's not worth the risk. Moto G is getting old now, if you brick; there might not be a firmware image to get you out of it. I will create a flashable zip when a TWRP backup is available.

alright then, i will wait for a stable lollipop 5.1 build. Thanks !
YOu can flash the 4.4.4 firmware and OTA it to 5.0.1
but if u flash 4.42 firmware,ur phone will be hard bricked
So whats u have to do is
flash 4.4.4---->flash 5.0.1---->flash 5.1
voila
Ok, so here's the thing: I have a US retail XT1032.
I flashed the GPE Kitkat into my phone to get the Lollipop update back when there was no Lollipop for US retail. When I had the GPE Kitkat, I did the OTA to Lollipop 5.0.1.
After that, I tried to OTA to 5.1, but the upgrade stopped suddenly and no upgrade was made. And here's where I screwed up.
A friend of mine told me that, from Lollipop onwards, you couldn't upgrade unless you had a locked bootloader. So I tried to lock it. The problem is that I couldn't find the 5.0.1 GPE firmware, so I foolishly thought that I could use the 5.1 directly. That rendered my phone stuck at bootloader. So I downgraded to Kitkat and now it works.
I'd like to get back to Lollipop, but when I try to flash the GPE 4.4.4 ROM, it fails at every step. I don't want to try the Motorola OTA because I'm afraid something may go horribly wrong again, and because I don't want the Motorola firmware but the GPE.
Is there a way to do that, or am I stuck in Kitkat?
You can go here and see if you can find the appropriate firmware for your phone.
Wipe, flash and reboot.
BTW, OTA updates will fail every time if you do not have a completely stock system including stock recovery.
