Development [TB-J716F] (Unofficial) TWRP for Lenovo Xiaoxin Pad Pro 2021

[Ungeskriptet]

Hi so I broke b_partition of the device need help/guide in getting the required files to flash to fix the issues. Using the fastboot --set-active b keep showing unknown option. Likewise flashing the stock rom using QFIL doesnt fix the issues . Not sure what i did wrong along the way.... Also tried flash fastboot method with the stock rom files doesnt help too.

The correct command is fastboot set_active b.

QFIL would actually fix the issue easily as it reflashes the partition table.

Are you sure it's the latest? What does fastboot --version and did you it download from here?

yes downloaded it from there still wouldnt work. In any case having issues now even with flashing via QFIL its showing system is rooted not sure why thats why most probably is the a/b issues of it.

I managed to repartition and flash the images manually. However, I could not fix widevine status f3, if im not mistaken, it was affected by modem/persist/efs partition. I managed to backup using TWRP and restore function is ok. But i got bootloop after restore .

HI was wondering where did you get specific files to flash manually via fastboot since iam having issues with it.

I've tried to flash an update zip by TWRP but I got an error message of slot A/B, so I've changed to slot B just for trying and rebooted it. now I can't even turn on the tablet, it doesn't give a sign even if I try to charge or pressing the power or volume buttons. any idea of how can I fix this and change it back to slot A?

You seem to have related issues with the twrp like me which happens to have the same issues, the only to fix is through EDL hence via flashing stock rom, in the forum there's a way to flash back rom via QFIL EDL mode

ty for the reply, I was able to flash by QFIL only after selecting Reset Machine on settings, now device is working fine. only thing that I wasn't able to do is lock the bootloader, every time I try I'm getting the corrupt message, but not a real problem to me. I've updated it yesterday to ZUI 13.1.555

Hello,
I bought the US version of the Lenovo P12 Pro From Costco.com, just want to add, US revisions do not need to go to "https://www.zui.com/iunlock" an enter you serial. After 3 days of trying, it never recognized my serial. instead I just started throwing Fastboot Unlock commands at it. The one that stuck was "fastboot flashing unlock" which brought me to the Prompt to Unlock the bootloader screen. Your second version of TWRP worked great with P12 Pro for Flashing Magisk. I'm on S212071_22022_ROW however its already telling me S212131_22040010_Q00243_ROW is available for update.

Lenovo P12 Pro is a different device, this TWRP is made for TB-J716F.

There is a port for TB-Q706F here though if you have that model.

You're right it posted to the wrong thread. I used the wrong tab, this had the guide section.

 

[frilalo]

Are there any roms? I can't find one ...

 

[Ungeskriptet]

@frilalo You can follow this guide to install a GSI ROM. I used Andy Yan's LineageOS build. Note that all GSIs have the same bugs that you're going to notice right away…

The thing is, that I don't have the 2021 Tablet. I think I have the previous one.

is it possible to make it support ota update?

No, once bootloader is unlocked you will no longer receive OTA updates from Lenovo. You should be able to install updates manually from settings though.
