Hi, I'm currently on RR 6.0.1 and I want to try N for the first time.
Any special steps before flasing RR 7.0?
If I take a nanbackup (of current MM) first, can I restore it later as if Nougat were never on my phone?
Thanks!

yes you can restore and forget. but you do need wipe system data and caches before installing nougat
Yes, I can make a nanbackup, full wipe (without sdcard), then try Nougat, then full wipe again (without sdcard) and restore backup, correct?
To sum up, sdcard can be left untoched when changing from 6 to 7 and from 7 to 6 right?
Thanks!
I did not went back to MM after all, thanks for the info anyway!

It could be because of new display? Or should I restore backup over stock 4.4.2?

Any idea?
Thanks in advance...
I would advise you first to install some rom (try the same you had earlier), or any other rom(stock based)
Then in twrp wipe all but internal, leave the internal. Then restore the backup (don't tick EFS..)
now I'm on Pardus HD RoM Classic 7.2 (D80220d), but I'll try your suggestion and i'll be back with the result.
Thanks.
Funny stuff... before wiping and restoring as you told me, I tried to backup current Pardus stock, but it fails at 40% of system backing up....
weird...
Try backing up on the usb otg. Then restore the previous backup without efs..

sorry for being a n00b, but how can I do that?!
TIA.
If you've got the usb otg cable, simply connect the usb flash drive(usb flash) to it and choose the usb otg after pressing backup. Why don't you simply try wiping, then restoring? Maybe you like the current system too much . If so, then you might consider if you need the old one.

yes, indeed it is a great rom!
But I have some stuff saved in that nandroid and I kind of need to restore it
btw, all i can restore from the backup are : system, data and boot. No efs, no other partitions.. what do you think ? can I continue with restoring after wiping dalvik, system, data and cache, leaving internal storage?
Try. That's fine. You could also try installing similiar or same rom as you did first time, then restore data only..

restoring in progress....
after restoring, should I just reboot or do I need to wipe something else? I guess that first option, but it's my first boot loop so maybe I did something wrong..

Try only wiping cache and dalvik cache.
dito... restarting....
OMG! My system is back again!!
Many thanks for this tech support session!!!
You are welcome
put [SOLVED] + thread name instead of the current thread name so people know it's fixed.
Before going into the subject, I'll say that I have tried to seach this matter in XDA and Google, but nothing showed up.
Okay, so my matter is that I can't restore my backup of stock rom(8.0) after I flash a 8.1 rom. I've backuped with official TWRP "recovery-3.2.1-2-oreo.img".
My procedures are :
back up stock 8.0(system, data, cache, efs) with official TWRP "recovery-3.2.1-2-oreo.img"
flash oreo rom(with wiping internel, data, system, cache) and boot it fine.
restore my stock backup with same TWRP
boot system
The results are :
Goes past boot logo
Boot animation('android one' with colors sliding) shows up
and... just infinite loop of boot animation.
The ROM I used is RR.
I think the main problem is related with encryption.... Just my thought, tho.
So what I'm asking is :
1. If you face the same problem as me?
2. If you aren't and you restore goes fine, please tell me your procedures including ROM used and TWRP used.
3. Whether it is safe to decrypt stock rom?
Thanks in advance!
You don't need to flash stock ROM again. You have a system image backup(system, data, cache, efs), right? Wipe data , system, cache if you are coming from any other ROM. Then reboot to bootloader. Boot into latest TWRP from Fastboot (don't flash). Then go to restore and restore the system image you had backed up. Don't restore efs if you haven't lost your IMEI.
I've done exactly as ypu told, but it doesn't boot...
Did you manage to restore without problem with your method?
Yes I was able to. No problem here.
What TWRP did you use? Also, what ROM have you flashed?
Used the latest TWRP by MohanCM for Oreo. I did it when I was on Lineage os and wanted to go to stock
@guy_infinity Okay, thanks for your answer! Gonna try out later, once more.
Hmmm.... Still didn't boot up.
I thought I had to do everything from the begining, but flashing stock with save userdata option rescued me.
P.S. does anyone know about the error E: recv error on uevent?
try flashing stock rom using mi flash and after flashing restore normally using latest twrp/deadman's without system image voila everything will be back
@arjunbalan1994 Big thanks for your suggestion! Will try that too later
Hi, did you solve your restore problem? I have the same w/ my Redmi Note 5 and stock Miui backup after flashing RR.
Thanks for your help
I was use 8.1 root and twrp recovery. Yesterday fastboot flash may rom and update 2nd may OTA
Don't understand : May rom is Miui rom?
And did you restore your miui rom 8.0 backup ith twpr after the fastboot flash stock?
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.
Hey,
My Mi A1 have TWRP, Magisk, and bootloader unlocked on Android 8.1.0, but I want to upgrade to Android 9 and go back to full stock device (bootloader lock and original TWRP), my question is, what i need to do before ? Just flash with miflash latest rom and check clean all and lock or I need to go back to stock on Android 8.1.0 and do ota update to Android 9 ?
Thanks )
You can wipe everything in twrp and then flash this
https://drive.google.com/file/d/1Uh4CR2-MXBYsSQL6BTnv4xpkCjEh7ZFn/view?usp=drivesdk
Then you can lock it.
Just make a twrp backup and save it to your sdcard or computer , just in case.

Thanks, so in TWRP I check all in wipe (dalvik, data, internal, cache and system)? And after that I mount data and drop the rom with USB and flash it ?
And after that i'll not have TWRP anymore ?
I try this, this monday
My main phone got damaged so i am using this Moto G4+ phone temporarily. Years ago i flashed Resurrection Remix Nougat on this and the phone is really slow and laggy right now so I am hoping flashing a stock ROM will fix it but i am not sure how to flash the stock ROM. I know about the fastboot method but i am worried about bricking the phone and i really do not want to risk bricking it at all since this is the only working phone i have right now. I am worried about all these different bootloader versions and the 32bit/64bit thing. My current bootloader version is 1.07. Should i fastboot flash the ROM given here https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 or do i have to do something else first?
Thanks
If you're worried about bricking your device, I would initially try flashing the TWRP flashable of the Nougat or Oreo stock ROM (from here https://forum.xda-developers.com/moto-g4-plus/development/rom-oreo-8-1-0-soak-test-t3873367 ) This TWRP flashable will update your system, boot(kernel) and modem and should not update your GPT/bootloader (so you'd still be on B1:07). The stock ROM is 32 bit - if you're flashing, I would recommend you wipe data, after flashing, before booting - so ensure you back up (e.g. backup system, boot, data in TWRP) and keep that back up off your device.
If anything does happen, restore your backup and reboot.

I was able to successfully upgrade to stock Oreo through that TWRP zip but unfortunately the phone is still laggy, Do you think that fastboot flashing the stock ROM or upgrading to custom Pie ROM will help?
