Default WARNING 4.4.2 Can NOT Be Downgraded

Informative Thread Google Cached

READ CAREFULLY
WARNING
DO NOT FLASH THE NEW 4.4.2 SBF FIRMWARE UNLESS YOUR CARRIERS FIRMWARE IS AVAILABLE.
FOLKS HAVE FLASHED OTHER CARRIERS FIRMWARE AND AS A RESULT THEY HAVE NO DATA CONNECTION,
YOU CAN NOT DOWNGRADE, SO IF THIS HAPPENS CHANCES ARE YOU'LL HAVE A PHONE THATS UNUSABLE UNTIL AND IF YOUR CARRIERS SBF SHOWS UP.
THERE IS A CHANCE THAT EVEN AFTER YOU FLASH THE CORRECT FIRMWARE, YOUR RADIO SIGNAL MAY NEVER WORK


I will not in any fashion help anyone to upgrade nor downgrade their moto, this thread is for info only. I personally will not take any responsibility for any issues. You own it ., you alone broke it

Motorola bootloader unlocking website https://motorola-global-portal.custh...-your-device-a

WARNING WARNING

DO NOT FLASH ANY OTA 4.4.2 ,OTA ROM OR ANY SUCH MEANS OF UPGRADING WITHOUT HAVING YOUR SPECIFIC CARRIER 4.4.2 SBF FIRMWARE AS A BACK UP



WARNING WARNING WARNING

IF YOU HAVE A LOCKED BOOTLOADER ONLY FLASH YOUR SPECIFIC CARRIERS SBF FIRMWARE, OTHERWISE YOU WILL END UP WITH A HARD BRICKED DEVICE
************************************************** ********

If you Frankenstein a way of downgrading do not post it here, this thread is not about tricks, hacks or any such garbage. This thread is to inform folks in the correct way of maintaining your moto to work. Plain and simple
There's a tremendous amount of firmware flashing which is causing harm to many users phones.
Realize that having a unlocked boot loader moto, regardless if its a DE will also suffer from hard bricks.
Unlocked boot loaders can flash other variants system.img's without to many issues
Modems are a different story, some user report no data with European modems, so I suggest using your specific carriers modems
Stay away from motoboot.img (boot loader) or gpt.bin(partition table) be warned
Remember you and you alone are responsible for any hard bricks
********************************
This is a simple chart what can and can't not be downgraded, Thanks to Dray_jr :thumbup:

the only OTA that can downgrade is 4.4 to 4.2.2 Post Cam

here is what we know right now that might make more sense

4.4 to 4.2.2 Pre Cam will Brick
4.2.2 Post Cam to 4.2.2 Pre Cam will Brick.
4.4.2 to to anything will Brick
4.4 to 4.2.2 Post Cam you are ok

************************************************** **************
WARNING if you manage to flash back to 4.4 or even 4.2.2 with the new 4.4.2 BOOTLOADER DO NOT UNDER ANY CIRCUMSTANCE ACCEPT ANY OTA, YOU WILL HARD BRICK YOUR DEVICE, PROOF BELOW

******** "it was running on 4.4.2 software, then i downgrade to 4.2.2. all was fine, but OTA killed it.

So after that, i read that 4.4.2 instaled new bootloader =( that cant be downgraded, and can bricked the phone, it was my mistake =(

So i think i should sent it to Motorola and if i lucky one, they should repair it, or resend new one. or if bad luck i will throw it to the trash =)"*******

I think the community would benefit if this were a sticky posted as a closed thread:

I don't even have this device and know you can't downgrade. Why don't you try reading a little instead of posting.
