Hi!

I have recently updated my TabX to v4.0 Firmware. Now fonts and lines look thin and blurry. If you look closely, straight lines have some dots next to them sometimes. I have tried to change system fonts but no luck. Since I'm sensitive to this kind of rendering issue, this is really stressful to me. (in fact this was the reason for buying an eink reader, now the benefit against lcd seems to have vanished.)

I have looked for the last v3.5.x version, as described here:
https://www.reddit.com/r/Onyx_Boox/c..._firmware_for/

but it only gives me the latest version, with
http://data.onyx-international.cn/api/firmware/update?where={"buildNumber":0,"buildType":"user"," deviceMAC":"","lang":"en_US","model":"TabX","submo del":"","fingerprint":""}

does anyone have a link to the 3.5 update.upx file, such as
http://firmware-us.boox.com/xxxxx/update.upx

or know where to find archive files so i could roll back?

Any help in getting the version back, or fix the rendering issues is greatly appreciated!

Thanks and best wishes!
