I'm a XT1032 user who updated to GPe 5.1 and I noticed it updated my bootloader to 41.19, given past experiences with the 41.18 bootloader it might no longer be safe to downgrade to KitKat 4.4.4 and OTA to 5.0.x as 5.0.x includes the the 41.18 bootloader.
We know from people who downgraded from official 5.0.x to 4.4.2 and OTA'd to 4.4.4 that the OTA procedure causes a hard brick due to flashing the old bootloader, therefore it might be wise to not downgrade to any KitKat version at all if you previously updated to GPe 5.1
yup going from 5.0.2 to KK (4.4.2 to 4.4.4) killed my moto g.
Flashed to 5.1 so if I need reflash I'd side flash to 5.1

I downgraded to 4.4.4 from GPE 5.1 without any problems, now updated to 5.0.2 from 4.4.4

perhaps going to 4.4.2 then 4.4.4 did it? Wheras if you went straight to 4.4.4.
Either way won't risk going to KK
even i have downgraded to 4.4.4 from 5.1GPE and didnt face any problem.
It is 100% safe to downgrade ONLY if you do not flash the old bootloader. Kitkat, or lollipop 5.0.2 can run on 41.18 bootloader and even older bootloaders, just remember guys, if you try to flash the older bootloader it will hardbrick your phone. Avoid flashing anh bootloaders at all.
Just avoid flashing the bootloader, and you can go back and forth between Android versions. If you downgrade you'll have the flickering bug, but nothing more.
Flashing the 4.4.4 or 4.4.2 bootloader on a device with 41.18 or 41.19 will likely result in a hardbrick. AFAIK.
My point is that the OTA from stock/GPe KitKat to Lollipop 5.0.x includes the 41.18 bootloader, it will attempt to "upgrade" the 41.19 GPe 5.1 bootloader to 41.18 which might cause a brick the same way going from 4.4.2 with 41.18 to 4.4.4 with 41.13 by way of OTA was causing bricks
I made a mess of my attempt to upgrade to GPE 5.1 , so I downgraded to to 5.0.2 and it also downgraded the bootloader from 41.19 to 41.18. I wonder if that means that the 41.19 bootloader will allow us to downgrade further?

I'm not sure, I wouldn't try it unless you know you can get it repaired for free, IIRC the phone refuses to flash the bootloader if you downgrade it using mfastboot flash motoboot motoboot.img.
In any case, if you guys get sick of GPE 5.1, just flash the Brazilian 5.0.2 Firmware image without motoboot.img and gpt.bin... Then you will have back all Moto features (and will remain in 41.19 for now)... When the 5.1 moto firmware image comes available, just flash everything, including motoboot and gpt, to replace the ones from the GPE firmware...
Even if the 5.0.2 firmware image for your specific country comes available, you can flash it excluding bootloader and partition table safely... Then wou will be able to OTA to Moto 5.1 when it comes available, because you will already have the new bootloader, so there will be no problem.
Luckily, I flashed the GPE 5.1 flashable ZIP from lost101... :good:
4.4.2 WILL KILL YOUR PHONE
The death will happen after OTA from 4.4.2 to 4.4.4.
Speaking from experience :highfive:
So, I am kind of in a mess right now with my phone and I was wondering if it was because of the bootloader. Can anyone please tell me the bootloader versions for 4.4 kitkat, 5.0 lollipop and 5.1 lollipop?

41.13, 41.18 and 41.19.
Please I own a SM-910H version of the Galaxy Note 4. I tried to flash the N5 ported Sixperience rom but I was experiencing a bootloop because my bootloader wasn't a lollipop 5.1.1 bootloader. I downloaded the 5.1.1 bootloader (910HXXU1COH4) and for some unknown reason I'm not able to flash via odin. It fails whenever it gets to "sboot.bi". I tried flashing the stock firmware, both lollipop 5.0.2 and 5.1.1 but they all fail when it gets to "sboot.bin". But I'm able to flash Recoveries and 910HXXU2COJ4 bootloader.
I reverted back to stock kernel and recovery and still didn't solve the problem. I tried to flash CyanogenMod 12.1 via recovery it also didn't work.
Please I need help to fix this problem because I'm afraid it might affect me in the coming months if I want to flash android 6.0 Marshmallow.
Below are the information on my phone frmware
My Moto G4 came with Marshmallow installed and I performed an OTA update to Nougat. I then unlocked my bootloader and flashed some custom Nougat ROMs (7.1.2, so newer than the newest official available version). Now I want to get back to stock Nougat so I can relock the bootloader and all that jazz.
As far as I can tell, only Marshmallow firmware images are available so can I safely flash that (I'm thinking "ATHENE_MPJ24.139-23.4_cid50_subsidy-DEFAULT_CFC.zip") and then OTA to Nougat from there or will that cause problems because I already (presumably) have the Nougat bootloader version? I don't want to brick my phone!
Note I'm using a retail United Kingdom XT1622 Moto G4.
Cheers all in advance,
treela
Ah ha! Found this:
https://forum.xda-developers.com/mo...owngrade-nougat-to-marshmallow-t3487201/page5
Got back to stock Marshmallow all OK
flashing back to marshmallow and being able to relock the bootloader after doing the ota wont really work. best bet is to try and find the stock nougat image and flash it.
This may be a dumb question, but can I flash a marshmallow ROM and keep the Oreo bootloader? Or do I absolutely need to flash a 6.0 bootloader?
I know I was able to flash a nougat rom and keep the Oreo bootloader, but I'm not sure if it makes a difference with a 6.0 ROM.
I have Custom ROM stock nougat
Can I install only the MM bootloader, do full wipe, and install a custom MM ROM, just for recovery?
Downgrade for recovery?
I'm confused about what you want to achieve, are you asking if you can downgrade to stock marshmallow from stock Nougat, to flash a custom marshmallow ROM?
If so, you could downgrade, but I would strongly recommend not using OTA updates on the stock marshmallow ROM if you downgrade, else you may hard brick your device. In most cases, you can't downgrade the bootloader in fastboot.
I'm not sure what you are asking for about recovery, can you elaborate?

if I want to return to MM
my logic card is in poor condition, in the part of the load center, I can no longer connect the moto g4 by PC

You can even stay on nougat firmware, there's no need to downgrade as nougat is official released and available for all countries
