Hello, i have g800h with 6.0.1. russian stock. I rooted and install twrp 3.0.0. My question is, what rom can i safe flash, because the most custom roms required 4.2.2 or 5.1.1 before flashing. Am i stuck on this stock and i cant downgrade?
you can downgrade if you want to. just be sure to do backups first

I did backup in twrp, but I read somewhere that I can't downgrade because of knox. What about repair firmware 4.4.2. It has pit inside, is it safe to flash.?

so i purchased a note 4 off swappa that was rooted it I was looking at flashing a lollipop rom. the phone is currently running android 4.4.4 and baseband n910tuvu1ank4, and kernel 3.10.0-2796035, [email protected] #1. I haven't flashed a rom since my note 2 so my memory is a bit fuzzy on the process. Do I have to update all of this before I can go ahead and flash a custom lollipop rom? if so could anyone be kind enough to walk me through the process? I am also running At&t off the tmobile phone. (would this explain why when I click software update, nothing happens? The phone doesn't even go to a page to try to check.) Thank you to any one that can provide assistance.
Follow the guide here to update to Lollipop before flashing a Lollipop ROM. In this thread you'll find all the files you need to update, root, and get a custom recovery so you can begin flashing ROMs. Most ROMs will have installation instructions in the first post of the thread.

thanks for the response. i have root already but im still on 4.4.4. im looking to flash lollipop roms. Do i need to update anything or can i just flash a 5.0 rom right over my 4.4.4 stock rooted rom? i reread your comment which files do i need to flash in that guide? the two cod6 lollipop files? maybe im not seeing it but in the guide i dont see how to uppdate to lollipop....
You have to Odin flash the COD6 lollipop firmware. Just flash the entire 1gb file. Then follow the steps in that thread to root and get custom recovery back

so if i odin flash the cod6 file that is 1.8 gb that will replace my kernel or do i need to flash that as well? and this will make me lose root. and will have to re root the phone... sorry for the question i feel like a newbie again to all of this....
Yes it will replace everything. Kernel,bootloader, recovery, modem, everything. And you will lose root. But you can just follow the steps in the linked thread to get root and recovery back. And no problem! We were all noobs once lol
Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

Thanks for your help.
I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks
Figured out. Thanks
Can anyone pls tel how do i downgrade from marshmallow 6.0.1 to lollipop 5.0.2?
Currently my bootloader version is 48.83. I dnt remember what it was on lollipop. Pls help!
Just use your backup that you made prior to upgrading to Marshmallow. If you don't have the backup, just flash a different ROM. Plenty of guides on the site.

I have made the backup. But i have heard about many people hard bricking the phone when trying to downgrade and then again upgrading via ota. Thats why i askd.
If u are on custom rom other than motorola marshmallow soak test ota.. you will not get ur phone bricked when downgrading. Hard brick occurs if u downgrad from soak test ota to lollipop. In your case u just need to flash retaildsdsall firmware via fastboot mood. Search for tutorials for reverting to stoc 5.0.2.
Just DON'T CHANGE BOOTLOADER. You shouldn't be able to downgrade bootloaders but Motorola screwed that and with M bootloader you "can" downgrade, but bootloader downgrade results in BRICK. Just flash the rom you want, EXCEPT THE BOOTLOADER. For custom roms you shouldn't have problems.

I have made a nandroid backup. Currently m on nexus experience rom. One of my friend was in resurrection remix (marshmallow) he faced some bugs so he came back to lollipop. It worked fine for him. But when he tried to flash the soak test ota, he hard bricked his phone... Why did that happen??

All I can say is that I was on Nexus Experience 10.0.4 (Marshmallow) but could not get adopted storage to work so restored my previous AOSP lollipop ROM from TWRP backup and no issues. My Bootloader is 48.82. I have never used the soak test version or OTA version of marshmallow.
I have also in the past restored stock lollipop V5.0.2 from other lollipop versions with no issues.

My bootloader is 0×4887 I am running a stock mm and I wud like to downgrade to lollipop to use the stellar kernel way shud I do...???pls help
Just a noobie....
Sry if tat was bad English..!!
Just don't downgrade your Bootloader and you should be fine, if you're using an easyinstaller script to flash stock Lollipop make sure and remove the lines of code that flash motoboot.img & I'd also recommend removing the line that flashes gpt.bin to be safe.
Hey guys. I've been out of the loop. Is it safe to flash the DOK2 baseband/bootloader? Or should i just stay on COG2? Does it still have problems with root? You cant downgrade to 5.0.1 or 4.4.4 after flashing right ?

If you wish to stay on 5.0.1 or 4.4.4, then its not safe. Correct, you cannot downgrade. I tried going back to Darthstalker (5.0.1) and it bootlooped after going to DOK2 baseband/bootloader. I heard there is a way to downgrade the bootloader, but its not a very straight forward way
Plus, to add to that, there isn't a regular root method i do not believe. It's Systemless Root with means you don't have full root capabilities
Just upgrade baseband only like i did. Its fine then.
Hi all, I recently flashed a 6.0.1 rom and updated the bootloader and baseband to N910TUVS2EQG1. I made a twrp backup before updating from 5.1.1 to 6.0.1. Can I restore that twrp backup on my phone? Would that change the baseband/bootloader back to 5.1.1 or those stay ase 6.0.1? Would the phone work restoring to a 5.1.1 rom using 6.0.1 baseband and bootloader? There are some nice features on the older rom that I like and would like to try restoring it.
Thanks!

You have to downgrade bootloader/modem to 5.1.1 otherwise your backup will not boot.
If you made full backup from twrp (boot/system/data/efs/modem) then you need just to downgrade the bootloader .
You dont have to flash whole 5.1.1 firmware to downgrade you can just flash bootloader via odin then go to twrp and restore your backup.
Get bootloader from link below
Choose BL in odin
