the version was running on the device when i flash it which is 3.5.3
First time i flashed the 3.5.1 update.zip
2nd time I flashed the update.zip of the link you just shared:
http://firmware-us.boox.com/c07f7139...a70/update.upx
I see that the size of this file is the same size with the 3.5.1 file, is it the latest?
But they all the same issue. Can not boot to the system.
