Question [SOLVED] Messed Up Screen Resolution...

[Alpacazilla]

Hi, so I was playing with ADB and changing screen resolution, I changed it to 50x100 and my device just rebooted. Now I can't access anything because the screen is so small.

Is there any way to reset the screen resolution without a hard reset?

Note: I can access bootloader/recovery mode

bootloader is unlocked?

bootloader is unlocked?

No, I tried installing an update through ADB, sdcard, or a custom bootloader, nothing worked.

unless you can connect TV or something there is no way other than factory reset.

Can you connect to TV? I tried using scrcpy to view the screen on pc but ADB doesn't connect if phone isn't unlocked.

I think adb will work on lock screen, because I have unlocked pattern with scrcpy myself. most likely it doesn't boot. to my excuse must confess that devices were not encrypted, maybe your device behaves different.

Yea... It was working before my phone rebooted after I changed the resolution, now when I run "adb devices" it shows nothing.

I have a Moto G Power (2021) and it won't connect ADB if the screen is locked.
What kind of lock do you have? Pattern, Pin or Paswword.
You should be able to type with a OTG keyboard.

Actually, even if you use a swipe pattern, there are ways to get that.
How did you set screen size? wm size?

Ha, You nearly did me in. I set my lock pattern to one that practically can not be done by a human.
Unfortunately the vertical position of the set lock pattern is not the same as the main unlock pattern.
It took me 10 minutes to unlock my device.

The only reward for failure is a factory reset...

The biggest problem is that it doesn't actually show where you are touching.
I'm trying to unlock it again with the display set to 800x360 res instead of 1600x720.

Edit: I did get it unlocked. Still, with 50 x 100 it could be tough.

don't forget the sim pin...

I have a PIN lock.
Well unfortunately I don't have an OTG.

Yes, I used adb shell wm 50x100.

Mmm, you have to use my usbcfg (also not listed yet) to configure the USB to adb,hid
You can run it as an init service or just as a shell command but you'll need to be rooted.
You'll also need to chmod 666 /dev/hidg0 or use ueventd.rc

By any chance can I root or do anything at all with bootloader locked?
I tried getting the UNIQUE_KEY needed for oem unlock, but it said I needed to enable oem unlocking at developer options, which I can't access.

 

[alecxs]

unlocking bootloader forces factory reset. again why don't you buy OTG hub??

I'm losing context here.

All that usbcfg stuff I was talking about is to use on a separate Android if you needed to pattern unlock a different Android.

If you've got the screen lock still stuck you'll have to do that first before you start talking about rooting.

I think all it needs is adb shell wm size reset
