Successfully Revert back to OOS 3.2.8 (MM) from Open Beta 8 (N)

I installed the N beta and have to say it was not working for me as I had a few bugs with it. There is a way to easily revert back to MM.
Boot into TWRP.
Go to advanced wipe and select everything including system. (This will delete everything including os from your phone)
Reboot and go into twrp again.
Flash 3.2.8 and SuperSu (optional)
Thats it. No need for any special build as OP said.

Thx for that Info. Have you been on F2fs or on ext4?

In my case I guess i can´t got beta 8 installed and twrp ask for pin did you think if i wipe data and flash 3.2.6 i manage to revert?

i was on ext4. to get on f2fs you have to hard reset your device after flashing beta.

I think you have enabled pin on bootup. You can try disabling it and then you should be able to get to recovery.

Thx. I am afraid, if on f2fs, it wouldnt be that easy, but good to know that it works if we stayed on ext4

you can clean reflash the open beta 8 instead of 3.2.8 which would take you back to ext4 then you can flash 3.2.8.

what is the file system by default in op3 and will installing open beta 8 change file system to f2fs or to ext4?? thanks

Ext4 is default. Whether ob8 changes it or not, i got no aim.

Thanks for sharing :good:
Very useful info.

Correct me if I am wrong, but this method to revert back to 3.2.8 will only work only if you have flashed open beta 8 with official twrp as the partition will remain to EXT4.
If you have flashed the update through stock or modded twrp recovery then your system partition will become F2FS so this method to revert back to 3.2.8 will not work as it need EXT4 system partition.

So I am guessing your system partition is ext4 and f2fs , right? Coz, after a clean flash the system will become f2fs partition (thats what I read)
EDIT: Oh, You need to do hard reset for f2fs..
Also, did you read another thread? the users who did a remote session with OP said that u need some certificate file to downgrade to official OTA. something related to encryption

No it remains on ext4 even after a clean flash. You have do a hard reset to change it to f2fs.

I wonder what happens if file system is changed to f2fs. Should we change the partition to ext4 in twrp before installing OOS 3.2.8?

Buddy,
"wipe everything", that includes internal storage.. I read that it's not a good ideea to wipe internal storage.
But, thanks for info.

When you say wipe everything do you also mean internal storage? I really don't want to wipe that if it isn't absolutely necessary.

I am on Arter's CM13 Rom with modified kernel and with cache, system and data, all on f2fs.
What all do i have to keep on f2fs and what on ext4 to install Beta8.
After that i can follow all the steps with modified recovery, right? Or do i have to flash 3.5.5 or Beta7 first?

I know that the OP3T only uses F2FS for the DATA partition.
All other partitions are EXT4.
So I guess they will probably keep it that way on Nougat.
The beta 8 kernel might actually support F2FS for the other partitions, but without the source code I think you can only try.
Personally I am running Nougat Beta 8 as mentioned with DATA only on F2FS.

it might be a silly question, but now reading a lot about ext4 and F2FS everything I am totally messed up. Below are the confusions/queries-
1. How can I come to know I am on which files system, ext4 or f2fs ? (if I have twrp installed)
2. can it be changed from on to other, if yes, how?
3. Two latest builds - stock 3.2.8 and beta 8 are on ext4 and f2fs respectively, is it correct?
4. If I am on beta8 (flashed via modded twrp), how can I downgrade to stock 3.2.8 ?

Everytime i reboot into TWRP, my phone get wiped...

Does anyone have encountered this issue?? It's really damn annoying... Thanks for any help

I did have it and it is very annoying, I installed TWRP Blue Spark and it solved the issue. I will look for it and if I find it I will share it with you.

What version of TWRP are you using? 3.0.3-1, 3.0.4 and 3.0.4-1 have all been working well so far.

This happens if yu are f2fs formatted and swipe in allow for modifications when booting in §TWRP. If you don't swipe, you can still flash roms. Not sure what's changing anyway...I formatted ext4 and have no issues right now.

iam using f2fs with latest twrp (3.0.4.x) and no such issues.
but i was losing apps randomly after booting into recovery, on older TWRP versions.

Installed TWRP 3.0.4 and everything seems back to normal. Thanks for ur help guys.
Now my next problem is 4g reception in France..
Cheers thanks a lot
PS: how do I know if I'm using f2fs or ext4?

I believe there was an option somewhere in TWRP to view all your partitions and their file formats. By default, only the data partition is formatted in f2fs, everything else should be ext4 (and maybe fat?)
Edit: If you select Wipe in TWRP, then advanced wipe, and select the Data partition, you can click partition options to see what the file format is (don't swipe right if you don't want to wipe it). Aside from data, every other partition should be ext4 by default.
There's also apps like disk info that can tell you the file system used as well.

[Question]How to gain root using F2FS partition on stock MIUI 8 stable?

I hope I'm on the right channel to ask this..
I successfully booted MIUI 8 stable with F2FS partition (data and cache) but root fails to install..I've heard it's much faster (or better) than ext4..in LOS, with F2FS, you can easily gain root using su add-in..been searching answers for almost a week now..any inputs would be appreciated.. TIA!

Check whether your partitions have been reformatted to ex4. Regardless, try PHH superuser, it worked great for me.

Are you using a custom kernel, or is f2fs supported in the stock kernel?
SuperSu is not working because of chainfire is using mount -t ext4 to mount data and cache. With a f2fs formatted partition that is failing for sure.

Someone please help

You have some partitions encrypted.
Decrypt your phone and try again.
Some ROM have encryption activated, initially.

Please read this thread:

I had done that earlier when i flashed TWRP for the first time and after that nothing like this showed. I am seeing this again after updating it again to 3.1.0.
So i will have to factory reset it again to make itwork properly?
And do i have to do it every time i update my TWRP?

And also what all should i wipe?
Should i wipe my whole phone storage?

the stock boot is always checking of /data is encrypted or not.
if /data is not encrypted, it will start encrypting while booting.
decrypt key is not known.

You will never have access to /data with TWRP,
if you can not provide the correct password.
This password is set by the manufacturer and not public yet.
If you boot the system you will have access to /data.
If you boot the TWRP you will not have access to /data.
This is not related to any update..

Believe me or read the other threads regarding default encrypting Android versions..
/cache is cache
/data is all your userdata and apps
/system is the os
/boot is bootloader
/recovery is the TWRP
there are more mountpoints, you can see them if you click on mount in TWRP.
I wrote /data encrypted and you wrote /cache wiping.

Also it doesn't ask for any password or anything just says unable to mount storage at the end while wiping cache and dalvik cache. I havn't flashed anything since some time soo can't tell if flashing ROM will work or will it show some error.
But a few months ago NO error was displaying and everything was fine

You think, it's perhaps related to TWRP version?
Well then you can boot the version before or another version w/o flashing...

You can flash twrp via fastboot, reboot to recovery and do a "backup" of all partitions to sdcard.
once done you'll find a folder called TWRP on your external sdcard, compress and upload to mega website then
