Has anybody sucessfully downgraded back to Kitkat after flashing Lollipop stock rom?
I cant seem to get system to boot, I just keep getting "booting recovery..." message after restoring a backup or even flashing stock kitkat with odin.
Anybody else had this issue and resolved it?
Worked after second flash of stock in Odin, I did however enable bootloader flashing so not sure if this was the solution or not.
did you wipe date/factory reset or not?

Hi I hope you can help me with this,
I was on a custom 4.3 rom running on old bootloader. I then
updated to 4.4.2 rom but my camera is not working only a black screen and giving
me a warning message " Camera failed" and once that happens
the whole system lags. I've read around that it could be a hardware
problem but when I switched back to the 4.3 rom the camera is working
smoothly again. I have tried 3 different 4.4.2 custom roms but same issue persists.
My question is could this have anything to do with my bootloader? I am planning
on flashing a stock 4.4.2 firmware with the new bootloader to see if that helps but what
worries me is if this doesn't help then I have no way anymore to go back to
a 4.3 firmware where my camera still works. Can you help me point to a solution
to this problem? Or which stock firmware I should flash to test if my camera
will work on that firmware.
Did you fully wipe before flashing?

Yes full wiped in Aroma, Formatted Int/ext card from Philz recovery, restored factory
from rom didn't help either.
What custom rom did you flash? Do you use the correct modem for the old bootloader?

I have tried Phoenix ROM, GoldenEYE , ECHO ROM, I am not sure if
I am using the right modem though I just flashed the file suggested on this page.
I'm on the Phoenix rom and it's running stable for me. I am also running on the old bootloader.
I had troubles at first after upgrading to 4.4.2, but after I wiped /system in recovery, everything worked.
You could try it. Make sure to backup /efs to your external sd or pc. Backup your entire internal sdcard, because it will be wiped. I didn't know that, so I lost everything on my sd
Perform a full wipe. Then wipe /system from the recovery (i used clockwork recovery). After that just flash and don't install any tweaks in aroma.
In according @_alexndr information about immposibility come back to XXUEND3 stock rom if you have XXUFN modem i have a question.
If i have a bootloop I have option to flash stock rom but i don't want beacuse i will loose opportunity to root again with towelroot.
So i can go to stock recovery and wipe data and cache and do factory reset, my question is: will this always help with every bootloops?
Is sometimes happen bootloop that help only flash stock rom?

not all the times AFAIK.
tried before when testing to downgrade from ND3 to NC2, bootloop, factory reset. go through boot... but all freeze and FC
hehehe.
if you have updated the bootloader, there's no way to go back to any older firmware than your bootloader.
But I didn't upgrade bootloader, only modem and now I don't have come back to old base...
OK I am running a 5.0.1 ROM, I have tried a few but all have some bug or other that eventually becomes annoying. The 5.0.1 stock is rubbish hence why I stuck a ROM on, I want to go back to stock but not 5.0.1, 4.4.2 for me worked fined, when I used kies to try and downgrade I got an AUTH Error, I presume because KNOX is tripped. Is there any way around this?
1. Make a backup of your internal data.
2. Flash android 4.4.2 firmware using ODIN but unticking "Auto-reboot" option.
3. Take the battery out when ODIN tell you PASS in green.
4. Put the battery in again and boot Recovery Mode -> Wipe data/factory reset + wipe cache partition.
5. Select first option: Reboot system now.
6. It should boot normally and you will have android Kit Kat again working perfectly.
Sadly it doesn't even go as far as flashing before giving auth error.
READ THIS BEFORE DOWNGRADING!!!!
Today i downgraded my friend's s4 i9500, downgrade was successful but the PHONE IS NOT DETECTING ANY SIM CARD.
moreover i lost my IMEI no. and when i checked in 'about' screen i saw BASEBAND is UNKNOWN . Read some instructions for backing up ur EFS data before downgrading this device.
ok so i was trying to go back to kitkat 4.4.2 from android 5.0 and not paying attention i flashed the stock NK2 kernal and put my phone in a boot loop and i cant get out of it ive tried to factory reset and cleared cache from recovery mode so is there an easy way to fix this?

You absolutely can't downgrade from BOE1 or later.
If the issue was only that you were downgrading from BOD5 or earlier and simply flashed the wrong kernel, flashing the correct kernel will allow you to boot.
If the issue was that you had BOE1 or later and tried to flash kitkat, you need to try using Odin to flash a Lollipop recovery image.
I have a Moto X Style XT1572 Indian version. I updated it to stock Nougat 7.0 via OTA when it was rolled out in India. Later in January I unlocked the bootloader and installed unofficial TWRP recovery for flashing custom ROMs. I did take a full backup of stock ROM immediately when I installed the recovery. Since then I'm using custom ROMs built for Nougat modem.
At present, how can I go back to stock Nougat? I did do a full wipe (except internal memory) and tried to restore the stock Nougat backup which I took in January. The backup always gets successfully restored. However, when the phone boots up completely and reaches the language selection screen(the first screen when the phone boots up), the phone reboots and goes into a bootloop just displaying the bootloader unlocked screen. The only option I have then is to flash any custom ROM again and they do work perfectly. So what must be restricting the stock backup to boot? Also, is there any other way to go back to stock Nougat?
anyone, please?

This thread looks like it has the nougat full firmware package for your phone. Try fastboot flashing all of it: https://forum.xda-developers.com/moto-x-style/general/xt1572firmwareclarkretasiaindiads7-t3735257
If that doesn't work out, here's another trick I've seen work on occasion. Restore your TWRP backup, but do not reboot into it. After restoring the backup, use TWRP to flash stock recovery, then reboot to recovery and do a factory reset with the stock recovery. Then reboot into the stock rom. That can clear up some internal storage problems that hang things up. There are other ways to do it, but this is easiest.

I'll give a try to the fastboot version.
