Is it possible to downgrade from oficial kitkat At&t???

Hi Guys, I have read some topics about downgrading, but im not fully understanding if this is only for people who is already rooted or if this will work for a non rooted device. In my case i have an At&t Lg G2 not rooted with 4.4.2 kitkat and wanted to revert to 4.2 so i can root and then flash a rooted stock 4.4.2 kitkat. Is it possible to do that, even if i was never rooted? I do understand there's no root for kitkat as of now.
Thanks guys.

Well since we use the lg flash tool I don't think it should be an issue so go ahead the last time I went back to stock was when the kk rom with root and recovery came out so I'm sure you should be able to

Yes you can flash back to 4.2 with Flash Tool. If you root 4.2 and then take the AT&T update to kitkat you will keep root. This is what I did.

How about a D802? its on the official vodafone kitkat rom, with the upgraded bootloader. Loki does not work on kitkat. Is it still downgradeable to any version of jelly bean?

I did it myself earlier due to bluetooth battery drain on kitkat. Just go to the thread Return to Stock LG G2 and follow the instructions listed. You'll have to download the tot file (ROM), the flash tools and flash dll. Just follow those instructions to the letter and you'll be on 4.2.2 in no time.

Alright thanks. I just wanted to know if there were problems with the bootloader as I also have an at&t s4, which prevents the bootloader from being downgraded and bricks the device if its done.

Thats exactly why i was holding back from doing the downgrade. I also had an s4 on att and couldn't downgrade it.

[Q] Replacing stock firmware

Hi,
I bought my Moto G from an online store in Romania. The phone is great, but my firmware is AsiaRetail and I would like to change it to a European one, or even the Global version. Can that be done without rooting my phone? Can I somehow select which version to install with the upcoming update? If so I would be very grateful!
Thank you!

Just flash eu retail firmware with xda guide. You don't have to root etc.

Yes but it seems like I have to unlock the bootloader. I've had a lot of problems with my last phone and lost the warranty because I wanted a stock android experience. This time I'm trying to keep it simple and safe (as long as I can before I start a flashing spree again)

Yes but it seems like I have to unlock the bootloader.

And talking about the flashing spree, I did surrender to it. Totally not worth it though, at least for now. Stick with stock, don't mess around, it's as good as it gets.

And what would I have to do to install a EU firmware without root or unlocked bootloader? All the guides I've found need at least one. Any help would be highly appreciated!

Dear friend, the following guide is intended for you. It does not require root, nor an unlocked bootloader:
http://forum.xda-developers.com/showthread.php?t=2542219
You'll probably want to wait until official 4.4.3 images are available - that way, you won't need to update your system after flashing, making for a very clean installation.
Enjoy

1. Unlocking the boot loader will wipe everything...yes... You need to take backup of everything before unlocking..
2. You need to flash custom recovery to root your phone... My sugesstion is don't flash anything as of now or root.
If you root your phone, you will get ota,but you can't install it... So once you installed lollipop,you root it..
3. Lollipop will support multirom..wait for some dev to develop it..
4. Rooting is easy.. There are plenty of guides there for rooting.. Wait for few days to get lollipop and root it..

5... You can't install any official update if you root it.. But you can flash the update if any one created a flashable zip

Downgrading From MM to Lollipop

Hey guys .... Good Morning
I have a question for you or i want to have ur Advise on " DOWNGRADING FROM MM (JAN SECURITY UPDATES)>LOLLIPOP
Is it Possible to DO ? I have Moto G3 XT 1550 2gb/16gb... I'm Asking This question CZ i think battery backup and overall performance of Moto G3 with Lollipop was brilliant . But i have read so many thread of many user saying that they had bricked their device while downgrading from MM to Lollipop . So I'm Stopping myself to do so at this moment friends is it possible to do and what I need to do to make it happen waiting for Reply frnzz
Thnx in advance :fingers-crossed::fingers-crossed::fingers-crossed:

I have done it.
Offcourse you can downgrade from Marshmallow to Lollipop. I did that 2 to 3 times, haven' faced any issues. What I want to let you know is be careful with each and every step when proceeding further.
I think you aren't rooted, so no TWRP. I have the same device, what I usually do is get the TWRP backup to an external sd card before messing up, so in case anything goes wrong you can directly roll back to the point where you started.
2 things I want you to know before starting :
1. If you are too much concerned that your device may get bricked, I think you must unlock the bootloader, root the device, flash TWRP and get a full backup and then proceed further with downgrading.
2. Usually if you are careful, you can directly downgrade without doing step 1.
Starting off
1. Download the stock firmware from this Link
2. After downloading follow this Link for flashing the Lollipop Rom.
I hope this helps.

U have done it before the security patches or after the security patches cz security patches upgraded the Bootloader and In order to downgrade i think i need to skip motoboot and gpt files am i right bro or correct me if im wrong

I never updated anything on lollipop, though it was rooted and had TWRP installed. I don't remember everything but I received the security patch updates, i tried installing but each time when the device rebooted the installation failed. (I think because of unlocked bootloader)
When Jio came up, I was having VOLTE issues on Lollipop so I wanted to update to Marshmallow but I couldn't do it over OTA update. I backed up the lollipop rom via TWRP and then manually flashed the marshmallow rom myself. Everything was good but I didn't like the vertical app drawer, so again I backed up marshmallow rom and then rolled back to lollipop rom with minutes. After some days I had to restore to marshmallow again. And after months, today I am on AOSP Extended rom based on Nougat. Excellent Rom.
So regarding you questions, I suggest you to go through the comments section of How to flash factory images page.
I already told you, if you are concerned then unlock the bootloader, root, TWRP. :good:

Sir the boot file is before the motoboot.IMG (bootloader) and gpt file
Is the boot file required to be removed as with the bootloader and gpt file.please correct me.
My name is Anshuman and I am from Rohtak ,Haryana
I have a moto g3 osprey xt1550 Indian model with viper os on it (viper os is a great ROM).Please reply as soon as possible.
Finally I tells you that you are 85% right. I tried by removing the gpt and bootloader file.

Do want to restore it to back stock 6.0.1

downgrade to 5.1.1
I downgraded to 5.1.1 using 6.1 stock reckovery for reset before flashing.
Flashed factory image without flashing gpt.bin and bootloader.img
After reboot i got a notification to completely deinstall motorola sensor-firmware in order to went back to a previous version.
Not knowing if this will brick my device, i only disabled the notification by longpressing it/ question mark/.. a screen opened where i could block this notification.
Till now i could not see battery life improvement compared to MM or N Roms

Yes you can downgrade by using stock recovery with having Motorola update notification but you can not do it with twrp recovery as it may be dangerous for your phone.I had done it successfully with stock recovery of 5.1

Sorry bro Motorola hasn't released the firmware and also it is not available on XDA also there are chance that we will receive them late but I'm not sure about that and bro first thing to relock the bootloader u need to have the same firmware on which u unlocked the Bootloader. So to relock the bootloader again u need the firmware latest with oct/jan/april security patches .

Relock bootloader-moto g 6 experience and custom room

Well, this goes for people who have the Moto G6 device (ali) I have the variant for colombia xt-1925-2 yesterday unlock the bootloader of my device with the fear that my phone would be dead or brick mode, anyway,the Rom Pie that there is in these forums, and has the problem that the moto Mods does not work either is not enabled to work the sensor as the main button, rom as Resurrection remix, Pixel experience but all failed, some per non-certified device for play store or play protect, or in cases the rom ali 9.0 treble that also had problems with distorted audio, it's not worth it, unlocking your phone are many errors that there are in the rom, fortunately I could re-block the bootloader of my Moto g 6
I could go back to factory firmware with bootloader oem_lock
regards
I leave images of the room ali 9.0
