Downgrading from 5.1 to 4.3 - Moto G Q&A, Help & Troubleshooting

I have the Moto G 1st Gen (XT1028) for Verizon Prepaid. I've had it for about 2 1/2 years and I really want to downgrade it to it's original operating system. I usually check here every couple of months to see if there's yet a way to unlock the bootloader, but no luck. I know there's the sunshine unlocker, but that isn't compatible with my 5.1 operating system. Is there any way to downgrade my phone back to 4.3 without unlocking the bootloader? Thanks for any help, I greatly appreciate it.

Hi,
Don't want to be rude, but answer is "no way".
Without unlocking, nothing to do... By the way, seems to be a bad idea to downgrade, risks of bricking your phone...

The error is Fastboot attempting to prevent you bricking your phone by downgrading to an unsupported operating system.

This is not possible for you - even if you could flash the firmware image. The only way to boot the Jelly Bean Stock 4.3 Kernel (and ROM) is to never update your phone's Bootloader. Once Bootloader has been upgraded, you can never go back. Stock Kitkat is the earliest option available.

he messed with his phone i some strange way. recovery says the kernel (boot.img) is wrong / broken...
i would advice him (as he gets into the bootloader) to: unlock the bootloader 1st (so he can load a new boot & rom on this) he can do this via this bootloader & moto website
when he is unlocked he should flash a stock firmware via bootloader BUT he need to LOKK THAT THE FW matches HIS MODEL!!! instructions & downloads of the firmware can be found here in the moto g hread.
good luck!

unlock bootloader steps given to me by motorola today

So..an error occured on my motorola razr hd xt926 183.192.15 (built in july) while downloading an app and I had to go to Motorola to get it fixed. Motorola rep gave me a link to enable the ability to unlock my bootloader allowing me to install a custom recovery and then flash a rom to fix my problem. He matter of factly told me this would work. I am waiting for this phone to get off work so I can make the attempt. I'm pretty new to rooting and unlocking so I thought it would only be right if I shared this info. I was trying to share that link, however...my newness status will only allow me to drive you crazy with repetitive questions, or gloat...
If you want the info you can pm me I think...I've been gutting and restoring my laptops lately so forgive my forum skills.. If you know another way...lead on....

How to flash back to stock software on D6603 - Bell Canada?

Hi folks, I've been updating my phone using the latest rom I can find on this site for my rooted (bootloader unlockable) Bell mobility D6603
One of the things that has been driving me crazy is that I always see the notification that a new software update is available but it can never 'verify' the software for me to download it. So I end up trying to find the equivalent on here which is getting really annoying. Also I'm thinking of selling this phone so I would like to find a way to stop these messages and to see if going back to a stock rom will allow the phone to update the standard way so I don't get emails from the buyer claiming I sold him a busted handset.
If anyone can help me out with either a way to get the phone to update without having to do it manually, or a way to flash a stock rom that does, that would be much appreciated.
Here's a screenshot of my current install:

The reason it cant verify the update is because you are rooted.
Find and flash a stock ftf for your device through flashtool and you will be fully unrooted and be able to download updates ota.

So my friend handed me a Razr HD and I just found that it's on stock JB, totally exploitable. So I rooted with Towel root and tried to run the Motopocalypse apk without results for unlock bootloader. What am I doing wrong?

You need to flash the stock KitKat 4.4.2 ROM with version number v182.46.10 or 183.46.10, then use towelroot to root it and then finally motocalypse to unlock the bootloader. Further information may be found here...

thanks for everything. I don't made any moves apart of the Motocalypse APK and re rooted with Kingo since the root looked unstable, but now suddenly the bootlogo make sound but don't appear any image. The Motorola logo and fastboot show but the screen doesn't show anything after boot. Previuosly tried to flash a recovery using Rashr (my mistake) and now the stock recovery it's gone and RSD Lite show "error fastboot command" or something. I just dropped in a repair shop

Question Downgrade from UI 5.1 to UI 5.0

Good day all,
I'm currently running the latest firmware update for the SM-S908W model One UI 5.1 Feb 2023.
The notification icon pallet is driving me nuts and I know there are work arounds, but I am interested in downgrading from One UI 5.1 to One UI 5.0.
Is simply flashing the stock firmware in Odin capable of accomplishing this task or is there a possibility of bricking or other unforeseen issues?
If it is possible, can someone direct me to a guide?
Please and thank you!
You can usually use Odin to downgrade, provided your bootloader is unlocked. Keep in mind that certain bootloader versions will not permit downgrading.

Thank you!
I used this video as a guide. I can confirm I have successfully downgraded to One UI 5.0!
Make sure you download the latest Samsung USB Drivers (https://developer.samsung.com/android-usb-driver) so your device is recognized by Odin.
Cheers

You can downgrade as long as the binary is the same.
You don't need to unlock the bootloader
