Downgrading Bootloader From Lollipop to Kitkat - Moto G Q&A, Help & Troubleshooting

Is it possible to downgrade the bootloader for my moto g from lollipop to a KitKat compatible version?
The mobile radio active bug is draining my battery quite badly and I want to go back to KitKat to get rid of it.
I'm on the using the XT1032

It's completely unnecessary to even touch the Bootloader. Every time you do anything with it, you risk destroying your phone.
Simply flash the Factory Firmware Image from here: (excluding the command to flash motoboot.img (Bootloader))

Or flash one of these zips via Custom Recovery (TWRP):

[Q][XT1033][SOLVED] Revert back from 5.0.1 GPE to 5.0.1 Motorola Stock

SOLVED! SEE HERE!
So, I softbrick my XT1033 while I trying to upgrade from Motorola 5.0 to 5.0.1. After I tried many ways to solve the softbrick, the only solution was revert to 4.4.4 GPE and upgrade to 5.0.1 GPE.
So, please all understand that I did not want to install GPE (I already knew that I will lose dual sim on GPE), but was the only way to solve the softbrick.
But, I really don't like the GPE, and prefer the stock motorola rom for tons of reasons, but the main is the dual sim function and the camera/gallery apps.
So, my question is: Is there a way to return back from 5.0.1 GPE to stock 5.0.1?
Thanks!
Yes!

Probably, you'll need to flash a new gpt.bin file. Once it's been done, you can flash the others files.
Cheers!
Ok... it works... but was a hard work to do...
1 - Downgrade from 5.0.1 GPE to 4.4.4 GPE(using fastboot, but without flashing gpt.bin and motoboot.img)
2 - Reboot into bootloader and reflash 4.4.4 GPE (now flashing gpt and motoboot)
3 - Reboot into bootloader and flash 4.4.4 Stock (flashing gpt and motoboot too). Start phone.
4 - Reboot into recovery and flash 5.0 Stock (adb sideload). Start phone, put 5.0.1 Stock update zip into internal memory.
5 - Reboot into recovery and flash 5.0.1 stock.
I had to download 6 differents roms and others files to solve this problem (about 2,2GB downloaded)...
And, WOW, now all is fine...
JAJAJAJA
Me too, brother. I had to download 4 or 5 different roms to make it run properly.
But, at least, I'm now running the 5.0.1!
Cheers!

Does step 2 downgrade the bootloader from 41.18 to 41.13?
Yeah Did some one with 41.18 bootloader tries this solution?
We cant go back to 41.13 bootloader...

Strange Line on screen

My XT1032 was on GPE 5.0.1 and decided to flash official CM12
I tried to flash but it wont worked (maybe because of the small /system partition idk) so i flashed via Fastboot the 5.0.1 Moto GPT and i was able to flash it
But now i get a weird line on my screen which goes from top to the bottom every boot like in TWRP on 41.18 (5.0.1) Bootloader which only disappear until the next restart when i lock the screen
Is there any solution to remove it permanent or will that happen forever also for next (stock-)roms?
Im a bit confused :/
This is due to Kernel and Bootloader incompatibility. New custom kernels need to be created to take into account the new Lollipop bootloader. When and if this ever happens depends on the kernel developers. The only solution at the moment is to return to Stock Android Lollipop, either GPE or Retail Brazil / Asia.

[Q] Advice, urgent

Okay so my moto g is on lolipop gpe converted, but i want to go back stock. i know how to flash it and stuff but is there a chance i can brick it due to bootloader differences or anything? like how do i go about this do i need 4.4.4 or is 4.4.2 ok? thanks. *URGENT*
To be safe, flash a 4.4.4 ROM but don't flash motoboot.img even if you don't have the 41.18 bootloader.
I was able to flash my xt1032 with the 41.18 bootloader back to stock Telus 4.4.4. I was even able to flash stock US Retail 4.4.4. I never tried 4.4.2 and I never flashed motoboot.img.

how do i know if its 4.4.4 or 4.4.2??
You'll have to look at the Moto g firmware names. Sometimes, you have to guess. It;s important because you want to ensure that the modem in your phone supports the ROM and carrier.
Do you have the xt1032 (i.e. falcon)?

yeah mate thats the one
What bootloader is on your phone? If you have the 41.18, you'll experience the ripple effect on your phone until you lock/unlock your phone using the lockscreen.

How to downgrade? (ANSWER QUICK PLEASE!)

I installed the Android Lollipop 5.0.1 GB OTA after flashing the Stock GB 4.4.4 firmware last night then flashed TWRP 2.8.3 and Aero Kernel. Now I'm thinking of selling my phone to upgrade to the second generation Moto G thus requiring me to reset the phone entirely, how would I go about this without bricking my phone? (Phone is XT1032)
I would flash back to stock 4.4.4 and OTA to 5.0 so the biyer doesn't have the ripple effect on the phone.
I had a phone with stock Telus 5.02 and I was able to downgrade to stock 4.4.4. Just don't try to flash motoboot.img.
Don't forget to flash a new logo too so the buyer doesn't see the unlocked bootloader warning.
So how would I go about doing that? Do you have a thread I could follow the steps of?

[Q] HELP!!! Moto G 1032 model lollipop reboot when uninstalling apps

Hello forum, basically, when I got my moto G, it was on 4.3, so I did all the bits, and the step i did after all the rooting unlocking etc was upgraded my bootloader to the lollipop one (ending in 8 i believe) - which i wish i didnt do, and cant downgrade to 4.4.4 (or can I without bricking)......right back to the story.......the problem now is, whenever i try uninstalling apps, or wiping data in any app etc, my phone does a reboot, I installed the brazillian 5.0.2 flashable rom (the optimised one) which worked perfectly, did all the correct wipes etc, but it reboots when uninstalling apps......, and thought i would try dirty unicorns....works well except the rebooting problem...... help....what can I do????????
I read somewhere that maybe to solve it, you gotta change runtime from dalvik to ART, but there is no option to change this....
There are no 5.0.2 uk images available that i have read (so i cant completely get back to complete factory settings)
I really wished i kept the KK bootloader!!!! so who can help me????? I want to try some of the great CM11 builds!!!
Since your bootloader is unlocked and you have the lollipop bootloader, I suggest flashing the stock 4.4.4 (not 4.4.2) ROM for your xt1032 (you will not be able to flash the motoboot file so don't bother trying), upgrade the Motorola apps via Play store, and take the 5.02 OTA update.

do i have to update to 5.0.2 again? as i want to try cm11 again
@audit13 is this a flashable zip, or do you need to do it via fastboot? as its got a bootloader included in the zip (4.4.4 kitkat bootloader)
The files from filefactory need to be unzipped and flashed via fastboot or mfastboot.
You do not need to do anything with the stock ROM if you want to install a custom ROM. All you need to do is install a compatible custom recovery and a custom ROM. I suggest flashing right to the latest CM12 rather than using CM11.
I suggested flashing back to the stock for your phone and upgrading to 5.02 via OTA to see if the uninstall problem goes away.
yep understood @audit13 read your other posts on this matter too, the reason I want to use a cm11 rom, is I had a moto g about 8-9 months ago, and there was a rom i loved, and it was cm11 based......will i brick if i do flash this cm11 rom? i know about flickering bug, and possible hard brick if i went back to versions below 4.4.4 ...... and i love cyanogenmod roms, as i dont get irritating moto updates etc
Flashing CM11 should not be a problem as CM11 ROMs do not touch the bootloader or modem.
so basically, downgrade to the 4.4.4 firmware file, and cm11 and im done? yeah?
You can try to flash cm11 directly over stock 5.02. If it doesn't work, you may have to flash back to stock 4.4.4, install recovery, and then flash cm11.
