[Lenovo P11] FoxVol:
Any solution or any idea for what is going on with the new tablets with production date of August-September 2023?

I recently texted that I got my XiaoXin Pad 2022 (TB128FU) from AliExpress with S000068_ROW Global ROM and after couple of hours I decided to try ZUI 15 (at that time it was only available for fastboot) and after that I stuck on that poor situation — only ZUI 14 and ZUI 15 boot up. Global ROMs (any of them A12-13 — no luck) — hangs out on the Lenovo logo, no bootanimation, if tablet is connected to PC in that moment, it shows like "Qualcomm HS-USB 901F Diag" and ADB status is 'unauthorized' unluckily. Cusroms like that EvoX and Pixel Experience by Sanaes (another QSSI fullROM not GSI) — also hangs out on the Lenovo logo but luckily ADB is authorized and I can see Live logcat in cmd on PC. But on that — I can't know how to fix that poor situation. No boot up. No bootanimation. Just Lenovo logo. Tried flash via QFIL ZUI 14 and 15 and after that cusROMs — also no luck. Hangs out and that's it.

I had a talk with Sanaes, he is an unofficial Pixel Experience mantainer and he built for me new build of PE with ZUI 15 blobs and that's kinda solution of problem on those new tablets. It boots up and system is working but with lags and some bugs like Camera (faceunlock didn't work and because of that — I can't authorize via Google Play Services). But it boots up! So, new tablets can run cusROMs too! But... What happened? Why we can't go back to Global ROM? And why new tablets boot system up perfectly if we don't flash ZUI 14-15 before cusROMs on them? So many questions and no answer from China sellers and Lenovo..... The miser pays twice? Ugh.

There are quite a few people with the same problem as mine, but most of them are happy with the situation they currently have (working tablet LOL), but it so unfortunately. No truth-seekers like me. Of course. We tried to talk with sellers about this problem and one of them answered us by providing a file with the ROM that they flashed on tablets before sending to the buyer. Maybe someone saw or heard about the archive "pad2022multilan.zip" — it also didn't boots up. We also talked with the guy from the Vietnamese service center, which published the guide for the XiaoXin Pad 2022 flashing to Global ROM on YouTube and, strangely, he sent us his file, but the ROM there is the same version as the one sent earlier by the Chinese guy — S000058_ROW. This is not the one I had out of the box. (Reminder: I have S000068_ROW).

Maybe there are some edits that would make the system boot? Or after upgrading to ZUI 15, there was some kind of internal protection against rollback to ZUI 13.5? Oh, yes, I forget about it.

If I try to install ZUI 13.5 (any of it) — tablet will go into softbrick: no reaction on keys and any pressing combinations, I must disassemble it to close the testpoint contacts and then flash ZUI 14-15 ROM via QPST for reviving tablet back to life, that's why most of people with the same problem as mine are happy with their situation now, before that many of them stucked with softbricked tablets.

But why can old tablets released before August-September 2023 safely run any ROMs at all? What the hell is this? What did we do with our tablets?

So... I understand that it's difficult, but... I could help with anything on my side (only the experiments and Remote access to my tablet, because I don't know too much in ROM development and how it work inside), the only thing that I want is just help find a solution to this riddle somehow. Only together we can find answers to these questions And we will be able to warn other users who also got into this puddle. Tablets are still on sale and most likely, newer tablets with a new production date will continue to appear.
