Thank you Super!
After the update (“Wireless update” in the HiPad Pro menu, then a “factory reset” (wipe data, …)) my new Hipad Pro is working properly, except a little blurry effect.
The little blurry effect is like a wrong character policy is used on the main page. When I walk through menus, this blurry effect is less. Note that I am in dark mode.
You’re welcome.
That’s the same as what I experienced when on Chuwi Stock system.
BTW I found an adb command to set resolution to FHD as you metioned. This link shows the command to set resolution via adb shell here.
adb shell wm size 1212x1940
adb shell wm density 320
According to Device info app, my display resolution is at 1940 x 1212 pixels and density is at 320 dpi.
If these command lines work, you don’t need to flash GSI ROM for fixing the blurry issue.

Hi Super,
thanks again for all your help!
Just a question…so if I understood well to follow your last comment I should:
- connect my tablet on the computer
- turn on developer option
- open the SDK Tool
- put my tablet on the fastboot mode
- write down the below commands:
adb shell wm size 1212x1940 (this is on the correct order…or should be 1940x1221)?
adb shell wm density 320
reboot the tablet
Can you please confirm in order for everyone do it if they desire it.
Please feel free to add any comments ;)! I would appreciate it.
Thank you
Hi manuelbrunopt,
adb shell can be used during the system running on. When you boot up the system, you can use adb command lines with adb fastboot platform tool by connecting your Hipad Pro to PC.
From the example of adb command line to set up FHD resolution, it’s as that order (1212x1940).
After applying the adb command lines, reboot once and see if the blurry effect is gone. If yes, that should be the solution for the blurry issue which we are looking for.

Hey super, I just tried now and… looks like the blurry effect is kind of gone 
!
To be honest I was already so used to the other effect that now, I couldn’t kind of compare the changes :P!
Even so…thank you so much, for solving already one issue…now the other one that drives me crazy is not having full screen mode on all the Apps, Gosh!
But is already and improvment, thanks to you!!

There is a way to compare the different between lower resolution and higher resolution setups. You can enter these command lines in adb:
adb shell wm size 720x1280
adb shell wm density 160
Reboot once and see the lower resolution look.
Set the resolution back to FHD by these command lines in adb:
adb shell wm size 1212x1940
adb shell wm density 320
Reboot once and see the higher resolution look.
The icons of the UI will be easily observed for blurry issue. If these adb command lines really work, I will create a thread about fixing blurry issue.

Super I was having a look, and at least from the interface, like icons it still has some kind of blurry thing on it…plus I realized also on the images from the Google search, all the images look blurry and not clean :(!
But from the Google Chrome and from Netflix “looks” better, but I can really tell you that was chances or not so well :(!
Maybe someone can try and have a different perception, because this procedures are quite easy to execute!

Another way to prove the lower resolution and higher resolution settings work is to screen capture and see the pixel resolution images of lower resolution setting and higher resolution setting. If the screenshots of lower and higher resolution settings correspond to the sizes that were set by adb command lines, then there may be chance of the blurry issue from low resolution of icons that do not match FHD display.
Hi super,
I tried and everything still looks the same :(!
Btw…do you have the stylus (pen)? I saw on the web, that with the current system then pen has a lag when you are drawing…do you know if happens the same with the GSI room?
Thank you in advance for your time.
When adb commands are used, the change is immediatly updated to the screen. It is simple to observe the result by making a big change with the resolution, ie by a change from 1940 to 720 and revert.
Thus, I don’t think it is necessary to reboot the tablet.
And because the change is immediatly applied, does the new setting is preserved after a reboot?
I have tried to flash the boot.img patched with magisk using qfil but the system didn’t boot, says the system is corrupt. Flashed the original boot.img and the tablet is working again. My last hope is trying to flash an unlocked boot.img

Does anyone have an unlocked boot.img to share?
There is a user who returned his Hipad Pro and got the new one with unlocked bootloader. But after he updated firmware via OTA update, his device got locked.
I read from some Android forums that you need to flash blanked vbmeta to bypass security check to avoid bootloops. You can download blank vbmeta here. If this does not fix bootloop, you can flash the extracted vbmeta.img from the Stock ROM zipped file.
By the way, it’s best to unlock bootloader before flashing patched boot.img to root your device.
Did any one test Android 12 as a GSI Rom on this tablett?
Would be nice to have Android 12 as an official update with widevine L1 to watch videos from streaming plattforms…
