Fix blurry issue on Chuwi Hipad Pro

Android Tablets HiPad/HiPad LTE
1

Fix blurry issue on Chuwi Hipad Pro by setting up resolution and dpi. There is no risk in doing this. Feel free to try this yourself.

  1. Open Settings > About phone
  2. Tap on Build number several times until Developer mode activated.
  3. Activate USB debugging
  4. Connect to PC
  5. Enter adb devices via adb fastboot platform tool and allow USB debugging
  6. Enter adb shell wm size 1600x2560 to set resolution
  7. Enter adb shell wm density 480 to set pixel density
    01 2560x1600
    01 2560x16001600×2560 271 KB

There is no need to reboot system to take effect. And the effect will stay even if rebooting Hipad Pro. If this is not crisp enough, you can try the following command lines
adb shell wm size 2424x3880
adb shell wm density 640

02 3880x2424
02 3880x24243880×2424 433 KB

Please note that battery will drain quicker with higher resolution. Right now my Hipad Pro is set to 2560 x 1600 pixels.

For fixing reddish issue, try using apps that can change or calibrate color profiles. Type icc color profile in Play Store.

Hi super :)!

Thank you so much for keeping helping us with this topic.

I will try it as soon as possible :wink:

Hello super,

Thank you for your information.
I immediately tried the original resolution of 1600x2560.
It seems a little better.
But I need a little more tuning.

Seems that changing the resolution does not depend on the SoC specifications.

By the way, Do you have any idea that why CHUWI change from the original resolution to the current resolution of 1940x1212?

Hello Tanzawa,

idk why Chuwi change the resolution to 1940x1212. Its Logo is also in this resolution when booting. When I set resolution to 2560x1600 everything is crisp. The contour of curvy shapes used to be jagged on my display. Now everything is crisp. The drawback of this higher resolution is quicker battery drainage.

Have you updated your Hipad Pro system via OTA update? If not, can you check your bootloader whether or not it’s unlocked?

Hello super,

I couldn’t check the status of bootloader or Lock.
Something seems to be missing, but I haven’t investigated it.

fastboot oem device-inf

----waiting something forever----

My HiPad pro did not need OTA, its already updated.

Hello Tanzawa,

No, please don’t update firmeware via OTA update, at least for now. Most users got locked devices after doing that.

Enter this fastboot command in fastboot mode:
fastboot oem device-info
You missed “o” in “info”

The easiest to check your bootloader is to enter bootloader mode. You can do this by 2 methods:

  1. In system, Enter adb command line:
    adb reboot bootloader
  2. When your Hipad Pro turned off, holding power + volume down. Until you see Chuwi logo boot up, release power. You will enter bootloader mode. You can see DEVICE STATE - unlocked or locked. Mine is unlocked. Hope yours also.

Hello super,

I get DEVICE STATE. it was locked.
I did not OTA update, and my HiPad Pro was WideVine L1 already.

Hello Tanzawa,

You need to do these before using fastboot to unlock bootloader.

  1. install adb driver
  2. go to Settings > System > Developer options > OEM unlocking

There are a number of Hipad Pro users tried to unlock bootloader via fastboot command lines but cannot do it yet. Seem like their devices need official unlock tool. Not sure if this would happen to your device.

Hi super,
Thank you for your advice.
I tried to your CMD line. But, the situation was not changed.
I can not unlocked my tablet.

So, I am going to waiting CHUWI’s formal update

Thank you for your sincere support !

How can i acces to adb fasboot platform?

Considering that they’ve re-released the tablet with a different processor (the Mediatek G95 I think we can assume that even if there is some kind of software update, it won’t be available for the SD662 version of the tablet, because they simply won’t bother at all.

I also think that it’s very unlikely that CHUWI will relase/allow boot loader unlocking tool… So all in all good idea of a tablet, as usual destroyed by beinga one off with 0 support / software.

I couldn’t agree more. This Hipad Pro is the first, prolly the last, Qualcomm device made by Chuwi. I’ve checked the features of MTK G95 Hipad Pro. This MTK Hipad Pro does not have L1 Widevine and no QC 3.0. Chuwi might wanna stay in their safe zones of MTK and SPD devices which they can make more profit and sale amounts. These devices require much less supports. Much easier to unlock bootloader and flash stock ROMs. Sadly very little Chinese manufacturers who make Qualcomm devices. I had high hope for QSD Hipad Pro after getting my hands on this. I will welcome MTK Hipad Pro users posting on this forum sooner or later. At least QSD Hipad Pro will have more chance to have supplies for parts like screen and battery. These will make Hipad Pro life last longer, maybe up to Android 15.

Anyways, in order to unlock QSD Hipad Pro, I will try to back up my boot and vendor partitions from my unlocked device via root method since I could not back up my device via QFIL. Whoever wants to unlock QSD Hipad Pro can flash boot.img and vendor.img by QFIL. Please prepare to flash the Stock ROM in case your devices cannot be unlocked with this way and get bootloops or bricked. After successfully flashing these 2 img files, reboot to bootloader mode by holding vol down + power (or whatever key combination that works) to show unlocked state like this.

Before doing this you should use QFIL to back up your device’s IMEI. And please note that your firmware version will be reversed.
