Tutorial : Decrypt And Flash Any ROM [ Working on Android 10 ][No data loss]

[ChandlerBingg]

Guys btw What's the procedure to move from a custom rom to another "custom rom" or "Stock rom" on an encrypted device ??

 

[tiga016]

Right after installing fastboot oos and local upgrading, I followed the instructions (no password ofc) and I used mauronofrio's version of twrp

Make sure the "full ROM" u flash is OOS when decrypting instructions is your motive.

I flashed OOS 10.3.2 that I downloaded from the OnePlus website

FLASHING INSTRUCTION :

Warning : Always Backup Your Internal Storage For safer side


Points to be Noted :
1 : Dirty Flashing sometime works. But might have hidden bugs.
2 : Remove the pattern and also fingerprints before flashing the rom.
3 : Always you have to flash twrp zip file after flashing rom. Else you will loose twrp.
If you are on some other twrp versions, Kindly download Compatible TWRP recovery IMG file from download Section and Flash it in recovery.

Follow the same steps. And don't quote entire op.

 

[chalkash3]

Do this work on other devices?

 

[flash713]

Follow the same steps. And don't quote entire op.

I always think to myself, "ooohhh ****"when I see someone quote the entire op. ?

Do this work on other devices?

There's only one way to find out. ?

I recently got my OnePlus 6t and just now came across your thread here and wouldn't have unless someone had linked to it on a 6t thread. :good:

 

[kaziupal]

Do we still need to flash magisk 19.4?

Is this applicable with my custom ROM pie decrypt if want to follow these steps to flash another custom ROM android 10 decrypt? Also, is it realy magisk 16.4 only when in android 10?

It should be Magisk 20.4. I was wondering if we should flash dm verity before or after flashing magisk...

 

[HatRiGt]

Should be after flashing Magisk. DM verity should be the last file flashed before booting to system

So the OP procedure is just not updated? Because it still stated 19.4 or 16.4 magisk version. Anyway, what procedure I must follow if I am from decrypted android pie custom ROM and I wanted to go to OOS 10 still with decrypted device?

 

[sethukrishnan]

I'm currently on the latest OOS, if I decrypt and flash twrp and root my phone, then flash magisk...will the safety net work ?

 

[tiga016]

Please update the OP if it is now ok to use magisk 20.4 because it is not clearly stated. Some procedures says 19.4 and some says 16.4. Also, in the "to decrypt" procedures it says "If you are flashing android 10, then flash only magisk 19.4 not 20 since it might break twrp". Is it still reliable or not?

 

[tiga016]

Thanks for the update. Anyway, I'm from Android pie and want to go to Android Q but when I follow the instructions on upgrading to OOS 10 it comes with error. Any A10 versions comes with error. Is there something to do with the type of recovery I have? I used bluspark TWRP 107. I'm still decrypt device but cannot continue.

 

[tiga016]

My device re-encrypt when I follow the instructions on how to decrypt. The no-verity file is not working on my experience. Maybe it is in the type of TWRP? Is it really TWRP 3.3.1.-11 that decrypt working? or just the OP link is not updated? BTW the latest TWRP decrypt not working.

Edit:
I successfully decrypt my device but with different verity files since the file included in the OP does not maintain my device decrypt.
