[Q] Restore KK Rom from LP Rom?

Hi, I came from CG3 KK rom then I flashed RR Rom w/c is LP Rom. Can I restore my KK rom directly or do I have to flash something like KK baseband first before restoring my backup? Thanks!

Anyone? Please. Thanks

Updating to Lollipop messes with all your initial KitKat partitions. There are 2 solutions to what you're asking.
Solution 1 (SAFE):
It's highly recommended you DON'T just flash a KitKat ROM back onto your device, this will render your device useless. Return to stock KitKat by using the Return To Stock method, then flash your KitKat ROM back over. Doing it this way will first make sure your device has the proper KK partitions. Of course if you have a KK Nandroid back up just flash that back on once you're back on KitKat , and if you don't have a KK Nandroid backup.. just make sure you back up your LP data/media before returning back to stock :victory:.
Solution 2 (UNSAFE, D802 ONLY):
This method unfortunately is only FOR THE D802 by somboons in this thread which I have NOT tested. It involves flashing a .zip to revert your KitKat partitions. More room for errors, but less work. Your call. Obviously if your device is not a D802, don't even attempt this solution, seriously.. just go with Solution 1 .
How to restore KK partitions/flash other ROM (credits to droidth):
- Download this flashable zip: LGG2 -droidth-fixed-KK-partition.zip
- Reboot to recovery and flash LGG2 -droidth-fixed-KK-partition.zip, DONT REBOOT!
- Flash backup or other G2 stock based ROM.

How to roll back to KK

Anyone have a guide on how to roll back to KK. I tried simply flashing the Stock KK rom but it stalls a Samsung logo. I think its due to the Bootloader which I updated to BOC3 when I installed Lollipop. I can't find the old Bootloader.

Before you flash the KK rom, make sure to Wipe data/Factory reset in recovery, then flash the rom using ODIN, once the procedure is complete, return to recovery and wipe data one more time. This should fix the issue and your phone will boot normally.

I had the same after flashing KitKat and then wiping cache. I had to factory reset from recovery for it to boot normally.

Currently lollipop N910c .BOC5
thinking of going back to kit kat.have not tried because it updated to lollipop immediate when purchased.
Anyone who did that.. did you check knox 0x0 ???

Flashing stock firmware through Odin will not trigger Knox 0x1, but keep in mind you'll have to factory reset your device.

Flashed back to KK
I have got a UK N910F and flashed a German ROM this ROM literally ate my battery, after reading this thread I wiped the phone and flashed KK and that worked, prior to this I tried to revert to KK (when I was on 5.0.1) and I could not revert back as I was stuck on boot loop..............Many Thanks

How to flash prerooted ROM to new android 5 device without root and keep knox 0x0?

Hi all,
I want to install ROM by _alexndr on a new G900F. I want to keep KNOX 0x0, so I need root to flash this ROM using flashfire.
However, the device came with android 5 when I bought it, so towelroot does not work. If I understood correctly, I have to flash stock 4.4.2 firmware (where do I get it? which tool to use for flashing? Just flash, or other things to take care of?), then I can use towelroot and flash ROM by _alexndr with flashfire. Did I miss anything important?

Get the ROM and ODIN the flashing tool from sammobile .com firmware section
Instructions under the download (Free account might be needed to download the ROM)

Can I just flash the old 4.4.2 firmware over the current 5.0 firmware, or do I have to consider something else?

I've flashed KK over LP before, and first boot didn't boot, flashed it again the same way, and it booted fine
Might need to factory reset before/after flashing if you have problems

Bootloop issues

Hello there. So, this is my actual situation: I have a galaxy s4 on stock Lollipop. Due a few issues, I decided to try to downgrade to kitkat I flashed via Odin a stock kk fw, but unluckyly I Haven't considered Knox bootloader, and now the phone stucks in bootloop. I tried to enter recovery, but it doesn't even work.
Is there any way to save it? Actually, I'm downloading stock lollipop firmware to flash it from Odin. Could it work ?
Thanks everyone will give help

Yes, flash the latest stock ROM in Odin to get the phone back to stock.

Downgrading from CM 14 Nougat to stock TW 5.0 lollipop???

Sorry if I'm posting in wrong section actually I'm a newbie
Hi all, I've updated my Note 3 SM-N900 to Cm 14 nougat 7.1.1 unofficial lonage os by ha_3g. Now i want to go back to my stock Twiz 5.0 lollipop, is it possible I've all my rom backedup by TWRP. Can i restore my backup without any problem?
Thanks in advance

nah,usually i just flash my firmware using odin without backup

Usually if you want to revert back to stock firmware, everything will be removed, including your custom recover(TWRP in this case), miscellaneous files and folders that were previously on your custom ROM. So, in summary, you won't be able to recover your backed up apps/data as TWRP will get wiped out as well, being replaced by the stock Samsung recovery.

Yep, wipe system, data, cache & dalvik then restore your backup.

Before updating I've backed up my stock Twiz rom via TWRP, now i just want to revert back to my Stock rom which was lollipop 5.0. I'm afraid bcz I've seen some where that we cannot install 5.0 (lower version) over 7.1 (greater) version it will brick the phone bcz of some bootloader issues, btw I've not messed up with bootloader, so plz advise me if it will be safe or not.
Lot of Thanks for the members of the forum who replied in no time & who r ready to help. Salute to all of u. you people r great

Only a stock firmware flashed with Odin can upgrade your bootloader.
And the latest official firmware for Note 3 is Lollipop 5.0.
So your bootloader still 5.0 even if you flashed a nougat rom.
Even more, custom roms don't touch bootloader or modem partitions, ever.
Go ahead

Hey bro. Just go to sammobile.com and download your rom and flash via Odin. Only Odin can downgrade your BL and Modem

Thanks alot for the clarification I'll go ahead now.

I can swap between 7.1 Nougat and 5.0 stock, with no issues, through my nandroids.
If you had a nandroid before, you shouldn't have any issue just using the TWRP function to restore your backup. It will be exactly as you had it before.
The only difference will be that you will still have TWRP installed, etc.
Anyways, you can swap back and forth as much as you like. You don't have to wipe anything, or use Odin, since you made a nandroid already.

Yes you can go back to lollipop . I have done that in my sm 900 exynos version. marshmallow and nougat drains battery
