i think the current stock rom which is the chinese rom is the best rom for pad pro 2021 now, it smooth and have modified gesture , feature for tablets, you just need to debloat app which you don’t want

Hi bro, will everything work fine on android 12 gsi, how about wifi and bluetooth function , rotation sensor ?

thank you very much @zxcv88 both 2 ota work well now , can you show us how to get these ota file like that ? It seem that lenovo block OTA on some devices which is out side of china mainland ( device does not receive any update from system update UI)

Did you try to reset factorey after ota

you can only use the buttons when you point the pen tip to screen , because this pen does not design like Spen from samsung so it just used only for note taking or draw (without bluetooth )

You can find any pen which support n-trig technology ? it can use for only Pro 2020 and pro 2021 version . That mean all surface pen or oem stylus pen which support for surface pro >= 4 can be use with lenovo pad pro 2021 with full feature like the offical lenovo pen

Can i know more detail about your issue ? Firstly you need to verify that your device is in qfil mode or not by "dmesg" command ? Then retry command in repo and upload result here

The answer is no gps

Hi tropaion, could you try install Android 12L for this tablet ? Android 12L is optimize for large screen , so i thinbk it is useful for our tablet

yes , netflix can nerver compare to kodi, kodi is very powerful , it has anything

you need to retry with another fastboot version, you should find some fastboot version in another lenovo thread, because i think fastboot lock command is for specific built version

you should buy from chinese store , you should not buy the global rom version , so with chinese version you will have stock rom with locked bootloaderla L1 DRM , you can play netflix full hd , i can confirm this point

please post the script with command "fastboot getvar all " , and the log when you run command to flash your patched boot.img file here, so hope that i can find your issue

i think you should write your question separately, and have some pictures of step by steps , so i can help you find the root cause and solutions

what is your exactly model ? so after you define your model you can find the correct firmware here https://mirrors.lolinet.com/firmware/lenovo/

you just need to flash with Qfil programing , so there will be no any anti-rollback

did you try to relock bootloader then flash stock rom again ? will this method can bring back L1 DRM ?

did you try lingeas os ? i think it's a good GSI

thabks for nice experience with gsi, if lenovo public their kernel source like mipad 5 pro i can developer custom rom for it, if not it hard to map correct hal driver to exactly application layer of gsi

the best way you can do is reset factory after OTA update it will help device clear all value in SQL database to default value

so you need to add persist.img file name in content.xml file, and you need to relock bootloader before flashig Qfil , so you can get L1 widewinee back again

you can root after unlock bootloade by patching boot.img from stock rom (by magisk ) and install magisk without TWRP

1. Yes you will lose L1 when unlock bootloader 2. No , TWRP with very different hardware so don't hope so much . I see there is no reason to root TB-J716F now, current firmware is stable and smooth

you need to check that Were sn.img and persist.img partition flashed in Qfil process ? If yes i think all system will be restored to stock and you will get L1 widewine back

yes qfil tool require very strict USB environment setup, if you can not fix sahara protocol , you can try install another window version, or try another PC/laptop , the last method is use linux environment

What do you really want to backup ifnyou flash with qfill ?? I think all personal data should be backup via cloud drive or Mtp to local pc, lenovo cloud drive can also support you to backup via app

You should follow the video on previous pages, you should choose Flat Build ,if you have issue with sahara protoccol please change usb port or try to flash via Linux environment

Actually, i'm using this tablet xiaoxin pad pro 2021, everything is very good, this tablet does not lock edl mode like xiaomi, so if you have any problems with firmware you can always come back stock

I think there is only one LMSA version here : https://support.lenovo.com/us/en/downloads/ds101291-rescue-and-smart-assistant-lmsa Can you give me download link for chinese version ? Thanks so much

Hi trojaner_80 , I think you understand wrong , sn.img is used for unlock bootloader , when you flash with Qfil on window environment , "Saha error" may come from USB environment and driver, tou can use linux to flassh it with qfil, it will be better with no Saha error

Do you know why this model is not available in Lenovo website and Recuse Lenovo LSMA tool ?

the correct command is "adb shell pm uninstall -user 0 <name of packages>"

I'm also want to find some cheap stylus which can work with xiaoxin pad pro 2021 . My purpose is for note only

Did you try it ? I think this method can work on Pad Pro 2021 SD870

Will we lose L1 cert if we unlocked bootloader ? is there any method to avoid losing L1 cert ?

Sorry sir, but i think you cannot flash persist.img thru fastboot, because it read-only partition ,

But can AIO tool reallly flash in EDL mode without Auth Mi account ? , or AIO tool will reboot to fastboot again and flash it ?

Hello sir , i would like to ask that if u use AIO tool method, so will fastboot be locked after unbrick process ?

hello sir can you help me , i face with the same issue, i message you in inbox please check it . Tks
