[OnePlus 8 Questions & Answers] nadnan:
Hello

I am happy to share with you my "meager" knowledge regarding the OnePlus 8 Pro device and TWRP

With my old devices (LG G3, Samsung S7, Edge), I used LineageOS roms a lot because it was a way to have the latest versions of Android, up to the equivalent of Oreo (Android 8)

To perform the backups with TWRP, I selected all the partitions and I also restored all the partitions: I then had a strictly operational and identical device at the time of the backup.

Since buying the OnePlus 8 Pro, in the fall of 2020, I have only installed Magisk, which gives access to the Root of the device and all OTA versions of OxygenOS, up to the current one: 11.0. 10.10

I have available Magisk installation links for rooting and lossless OTA update installations of Magisk.

I hadn't used TWRP because the latest versions weren't suitable for OnePlus 8 and Pro or T series beyond OxygenOS 9.

On the official TWRP website, the links for version 3.6 do not bring a file.

You have to use the XDA link

To get to the TWRP file download link in version 3.6

OP8/8PRO TWRP - Browse /beta_builds at SourceForge.net

sourceforge.net

For my part, I downloaded the "twrp-op8-3.6.0_11-infected-b5.img" file which has since been updated to version twrp-op8-3.6.0_11-infected-b7.img ago 10 a.m. as of this writing.

I installed the file as indicated on the thread:

fastboot flash recovery_a twrpname .img

fastboot flash recovery_b twrpname.img

Then, I was able to restart the OnePlus 8 Pro in Recovery mode (rather slow loading) and I then performed my first full “Nandroid” backups by selecting all the boxes (see screenshots)

For the moment, I stopped there: I did not dare to restore these backups, to find out if the device worked in a completely identical way, before launching a custom rom other than the original roms provided by OnePlus: I was unable to find any threads relating to "Nandroid" backups of the OnePlus 8 series.

On the other hand, I never used the MSM tool and I always did the backup/restore with TWRP which I was used to, I never did with fastboot commands, except for installing TWRP 3.6.

Above all, I have never tried to modify the partitions of the devices, old or current. My knowledge is nil in this area, especially with the new “dynamic” scores!!

I've tried app backups with "adb" commands but haven't been able to restore app-related data like I can with the "Swiftbackup" app discussed below.

Finally, so far on the rooted OnePlus 8 Pro, for my app backups, I use the "Swiftbackup" app.

Swift Backup - Apps on Google Play

A simple, fast and smart backup solution for Android smartphones

play.google.com

which works perfectly identical to "Titanium Backup"): this last application has been obsolete for several years and is no longer updated for the latest versions of Android (9 and beyond)

This "Swiftbackup" app performs a backup / restore of all installed apps WITH their data, locally and / or on the cloud, with or without system settings and apps on the condition of having a rooted device.

For my SMS, MMS and call log backups, I use the SMS Backup and Restore application: https://play.google.com/store/apps/details?id=com.riteshsahu.SMSBackupRestore

To tell the truth, I don't really need TWRP but I'm curious and I wanted to see the possibilities brought by TWRP 3.6, only suitable for OxygenOS 11.

This is where my knowledge is that I share with you.

The version of OOS 12 should arrive during the 1st quarter (already released in India) but it will be necessary to wait for the version of TWRP which will be adapted to the latest OS from OnePlus.

I remain of course at your disposal to continue to exchange about TWRP, within the limits of my knowledge!!

Best regards,
