Allwinner A13 Q88 - Touchscreen does not work

Question

linux

Hello!

After installing CyanogenMod according to this instruction, the touchscreen stopped working, although at first I specifically recognized the name of the driver. The firmware was successful, the installation of the touchscreen driver from the display was also successful. But the touchscreen didn't work. I tried all the drivers from that article, but none worked.

Unfortunately, I forgot to backup the OS before installing CyanogenMod.

Answer 1

If you boot into the recovery or bootloader via adb, does the touchscreen work there?

Answer 2

I installed the same firmware on my Q88 with the gslx680, everything works.
But first, by mistake, I installed the driver from the previous firmware build (they are directly on the link, for the latest driver build in a separate folder), with it the tablet hung when loading.
There are backups, if necessary, I can upload them.
