When trying to use TWRP backup, I can see the following prompt and the backup fails:

Failed to mount '/optics' (Structure needs cleaning)

What's the role of 2 partitions: /optics and /prism ? Are they really needed for Nandroid backup? If I simply ignore them, my backup goes through. What's the most recent TWRP version which allows you to back these partitions up? The one available in Dr. Ketan's downloads (Sep. 21) doesn't seem to handle them.

Thanks and Regards!

Does this work on att 5g, and does it work on a 986b/ds? I'm trying to buy a phone on ebay that will work with this rom and will work on at&t's 5g network. Since I have been out of the root game for a few years I'm struggling to figure it out. Any advice?

Hi,

How did you get this good result
🙄
My device has 18hours without use and 1hour screen on time since i have get the device, and that's with all apps in deep sleep, only messaging app not in standby but no they have less battery drain,

I hope for so long time for a custom kernel, to change cpu clock, voltage, and government and so on

What tool for a *complete* backup ? Last times I clean install Dr Ketan rom and do a restore app+settings I have to manually reenter a lot of security settings (pass, unlocks etc.). I tried a couple backup apps. Do you know one that restore as identical ? I thank you.

Restoring app+data is concerned, swift backup is best in my opinion
Still many apps login via web authentication and can't restore password, for that you can use Google auto fill and password

Format Data from TWRP. Note again, Format data (when you needs to type yes to confirm) not factory reset. This will wipe everything from Int storage.

Any Snapdragon version support likely at all please for Note 20 Ultra from Dr.Ketan???
No. Have no more spare time to add support for more devices
For the BL and Modem update, do I flash them and let the device reboot or do I flash them and reboot to twrp?
Sorry for asking but I didnt really understand that part on the txt files included in the BL zip file, I am in R10 currently.
Either way. You can first copy required files on device, flash bootloader and modem (all three files) with odin and then reboot to TWRP and flash rom
Or
Flash rom and before rebooting, flash bootloader and modem (all three files) with odin
