What does it fix?
GSI without unlocking BL?
rotation in GSI
Wallpaper can be changed?
screen lock after apk install? (required a back action to resolve)
unstable brightness issue? (require 60hz to get better)
HDR fix?

Good news!

Is there also ZUI 14 for Xiaoxin Pad PLus (TB J607F)? If yes, could the one share it.

Thanks in advance

This is great. Can I go back to ZUI 13 after updating to ZUI 14 using this image? (if issues arise with new version)

Getting this error on Google Play Store "retrieving information df-dferh-01" after updating.

Is there a way to fix this?

Thanks for the answer, but it did not help me (link is broken)
The issue was resolved as follows:
Went to settings, then apps. Click on the three dots at the top. There I chose google basic services. Turned off the switch. Tried launching chrome and logging in. There was a request to enable Google services. Then I went to the application settings and turned on google basic services. After that, I was successfully allowed into the account.

Hmm is it worth losing PC mode on on the latest update? I'm sure it's still in there since it activates when using an external display but hopefully there is a solution (like an app perhaps?) that lets you switch to PC mode just like the Xiaomi Mi Pad

    This helped me restore my Google Play Store after it shows DF-DFERH-01 error. Thank you!

    Note: Even if the link doesn't work, I just downloaded the latest Google Play Store from APKMirror and followed the procedure.

    How did you put the tablet in Spanish language?
    With this app
    1
    turn off the tablet. Then turn it on by pressing the power button and volume down button at the same time. will call on that screen there. Where the device state is written and this will tell if the bootloader is locked or not.

    This allows you to use pc mode on zui14

    If you change the zui_pc_mode in the system table to 1 using setedit or adb, it immediately switches to pc mode

    Have you activated "Google Basic Services" ?

    This option is in Settings > App Management > tap the three dots in the upper right corner > Google Basic Services. If you have deactivated you activate it.

    I installed Google Play Store from the Chinese app store that comes in the tablet.

    Search for play store there. It worked for me.

    Since you've already made a lot of attempts, you might want to restore factory settings to start from scratch.
    Hello, it worked, the issue of basic Google services had not been answered, it was resolved, thank you very much

    I took this chance to try ZUI 14, however there were definitely a lot of issues I've encountered.

    It wasn't able to root, wi-fi gets broken, and other issues that were already mentioned here. [1](The Google Account issue that was mentioned here didn't happen to me, I got it first try.) I actually got TWRP to install in ZUI 14 (credit goes to @Ungeskriptet) however it had issues mounting the system partitions. This was the same issue that happened on Android 12-based GSIs on this tablet.

    Though I'm actually curious that the update moved the whole OS to Slot B instead of staying in Slot A. The boot logo also changed to Qualcomm's logo instead of the usual Lenovo logo, as well as the unlocked bootloader message not showing up after.

    There were two new bootloader options too, one being booting into FFBM mode.

    In conclusion, stay away from this specific ZUI 14 update for now until there is news of a more stable update.

    [1] I might have been lucky the first try I installed ZUI 14. Now on other reinstalls, they don't seem to work now.

    Using the Chinese VPN software, I was able to OTA from ZUI 13.1.560 to ZUI 14.0.127.

    The process was flawless and til this moment I have not found any problem.

    Seems that Lenovo blocked OTA for the Chinese ROM outside Chinese network, because I have tried many times unsuccessfully. Before this update I was able to use OTA normally.

    I saved the full upgrade file (13.1.560 >> 14.1.127) and shared it in the link below:

    ZUI 14.0.127

    I used the Chinese VPN app mentioned in this thread, I used my Google account to activate the free trial.

    Once you're done you can remove access to the service following the instructions here - https://support.google.com/accounts/answer/3466521?hl=en

    I paused the download of the update once it had started, closed the VPN and then it downloaded at full speed (1.5 minutes as opposed to 8 hours via the VPN!)

    Google Play Store worked immediately for me.

    Thanks for the help and pointers from everyone here.
