Hi, right now I'm on CM 14 and would like to try Oxygen OS 3.5.6. If i do Nandroid backup of 3.1.0 using TWRP can I restore it back without loosing IMEI from 3.5.6?
I think our twrp doesn't backup both modem partitions, even for full nandroid..... Just back up the modems manually.
Hallo, basically my Problem is described as in the title.
I tried 3 Roms,
xXx Oxygen Os
Lineage os 14.1
NitrogenOs 8.0.0
and flashed the fixer script multiple times.
Still can't access anything.
Is there any other way I could restore permissions??
I'm on a trip and can't use my pc right now :/
I've never tried this before but maybe the fix contents option in twrp?
Try formatting data and flash permission fix zip before flashing and booting into ROM.
I explain my problem, after taking time trying roms 8.1 I decided to give a second chance to the stock-based roms. After several attempts with a couple of roms, I always get the same problem after installation (so not installed). I have read that it may be a problem with the version of twrp (right now with the latest version). Before trying to download the version I have to do something special, install as an image and go? Do I lose information when doing it?
What steps should I follow to go down to 6.0?
Besides this, I have a backup made of the gizrom, every time I want to restore it I get the same message: so not installed
Thank you

Backup everything on your internal storage while you are on 8.1 rom. Or restore 8.1 rom and do the backup now.
Even you had tried to restore 6.0 stock rom (unsuccessfully) you can still restore the 8.1 Twrp backup it should work.
Go back from 8.1 to stock 6.0 you can restore the 6.0 backup in Twrp as normal. But after restore the backup done you will need to format data. From Twrp menu go to: Wipe > Format data (here you will lose everything on internal storage). The stock 6.0 restored rom/system will still there and working.
You can restore the app data of the backup rom after you done with the format data.
If you don't do the format data the 6.0 rom will not work I think. It will show something about encryption stuff when it try to boot and enter the system.
Please help me guys.
I can't install any custom rom (I tried lineageos, aosp extended, carbon rom, ressurection remix), Everytime I try to do so, either it bootloops or is shows encryption unsuccessful error and I have to solve it by flashing stock rom using MiFlash.
Once I successfully installed lineageos 15 but since then I never succeeded in installing a custom rom.
[backup data IMP]
install twrp recovery via fastboot
do "factory reset" (wipes everything)
flash custom rom
reply if it worked!
If i backup my data using twrp>>backup and then factory reset, backup will also be removed?

Guys, I'm not very mature with this device Rn7. As i already know about it's encryption. It's v flaky.
I'm running LOS 17.1, i have setup Pin & Fingerprint in my device which i enter into the recovery as well for decryption. I never flashed a Firmware thingy in my Device. As i have read before flashing many ROMs, You should have to flash Android Q firmwares on Top. But i never did that when flashing LOS 17.1. I just rooted Miui 11 installed custom recovery (Orange Fox R11) & flashed LOS 17.1
Question 1: LOS 17.1 is FBE or FDE?
Question 2: If i want to move on to Bliss ROM 12.11 from my current LOS 17.1 (21.7 nightly), Formating data will be necessary? Or i can just wipe? So i don't loose my Internal storage.
Question 3: Does anyone know how to flash a firmware? BlissROM OP says flashing a firmware on the Top before flashing Rom.zip?
Question 4: If i want to backup (nandroid) my current OS (LOS 17.1) into the recovery. Exactly which partitions i should backup? So i can restore after trying Bliss ROM or if i get a bootloop or other issues (if needed). My Internal storage will be safe at that time aswell after restore?
My Current OS: LOS 17.1
Current Recovery: Orange Fox R11
LOS 17 is fbe. idk the rest

1) LOS 17.1 is FBE
2) when changing ROM is recommended to clean flash and format data but you can try to install the new ROM without formatting data, in case of bootloop or issues booting the system the only solution is to format data or restore the nandroid backup of the previous ROM
3) download the latest stable firmware (for your region or the global one) from https://xiaomifirmwareupdater.com/firmware/lavender/ then just flash it in recovery
4) read carefully this post: https://forum.xda-developers.com/re...ngefox-recovery-project-t3941822/post79771469 remember to copy the backup to a safe place (external sd card or computer)

If i flash the firmware on the top first. & Clean flash the ROM but without formating data. & if the ROM bootloops, i can just format the data & reboot the system? I will have the working device with newly flashed ROM? Or i will have to re-flash the whole ROM. zip again after formatting the data if newly flashed ROM bootloops?
Necessary to know for me, Because i won't have ROM.zip into my internal storage then if i will format the data when the ROM bootloops.
In addition to what others have posted, I would add :
- you can flash firmware anyhow.
- only /data and internal storage parts. are needed in most cases to be backed up. But that depends on what you wanna backup. I personally do not recommend relying on nandroid backups for data because of encryption. It is a hit and miss and you dont wanna take the risk in regards to data I believe. Just use an app data backup tool instead.
- Efs, modem, persist partitions should be backed up at least once and should be saved in different places because they can help fixing rare issues of imei lost, fingerprint breaking etc

Format data after flashing the ROM and then rebooting the system should be ok and you don't need to reflash anything
