Will this work on Lenovo TB-7305F?

Probably. You can try and write

The best custom rom for TB-7306F is AOSP 11.0 v313 from phhusson

Release AOSP 11.0 v313 · phhusson/treble_experimentations

Ive tested too:
lineage-18.1-20220715-UNOFFICIAL-a64_bvS.img.xz - its slow for me and sound is bad
and
superior-a64-bvN-userdebug.img.xz - works fast but sound is very bad

no

DONT flash super.img

Do this:
reboot tab to botloader mode (fastboot mode)
fastboot flashing unlock
fastboot reboot fastboot
fastboot flash vbmeta vbmeta.img (use vbmeta from aosp 11 from official android developer site)
fastboot reboot recovery
enter fastboot (into fastbootd)
fastboot flash system system.img
wipe userdate
reboot and wait 5 minutes and work

The only one custom rom works for me (tb-7306f) is:
dotOS 5.2 arm32-binder64-ab // gsi a64 - please download from official dotod site

If this doesnt work try again but without flashing vbmeta, maybe it work.

Have you got a link for the vbmeta
.img please?

I take from oryginal google aosp 11 and worked

I'm struggling to find the file on the Google asop 11 website. Are you able to point me in the right direction? Also would I flash the.img file in the fastboot folder? Sorry a noob. Many thanks

You don't have to be rooted and the image is good. In Windows,. I used fastboot command as follows: fastboot flash super C:\super.img and it seems like nothing is happening but give it a minute. It started flashing 35 files one at a time. Worked very well for me

Thanks, i got a flash error header at flashing beginning, decided to go and finished the 35 files. Now tablet is in an endless boot. I'm recovering the tablet with Lenovo rescue and will try to download super.img again, maybe it was corrupted.

UPDATE:
My error was not "fastboot reboot recovery" and wipe after flashing files. It works now, thanks

UPDATE2:
After a few days of use I can't recommend this ROM as it is eventually as fast as original ROM withou any better feature as it would be to have split screen ability.

it worked up to flashing system sytem.img launching an error after first file stating about a partition error

I have the same problem.

I installed lenovo rescue. I turn off the tablet. Hold vol+ and connect usb. Unfortunately (apparently the lenovo program does not see the tablet) the recovery does not start. As long as I hold vol+ the tablet turns on and then reboots. When I press vol+ it boots into fastboot mode.

How did you proceed?

If you follow rescue instructions (forced turning off by keeping pressed specífic buttons/time, etc) and doesn't work i would change of usb port, usb cable or even pc as it really works, i rescued mine several times. Good luck

See attached settings

Hi Deanventure, i have the same exact bluetooth issue you described, and was happy that you found a fix... however, i searched far and wide in all settings and cannot find the menus showed in the screenshot that you attached ;(

Any chance you can explain in more details what you actually tweaked and how to get to do it?

Thanks in advance!

I thank you for updating us with your experience of this ROM. I was going to flash it, just to try, but I don't think I will now

DotOS is okay, it works fast enough, faster than stock, so I guess that's good. It's a very basic device anyway so what can anyone expect?

 

[Dulence]

Hello..i need some help. I need to turn off the message for asking the permission when i try to connect usb camera (web camera) on this model of tablet..and go straight to app (Usb camera pro). The app is trying to start when i connect camera,but first i need to confirm it..would installing this version of Android help me with that? Thanks
