Thanks, but i'm sure that i have already try. But i will retry.First try "wipe cache partition" and after install from internal/external memory.
Kingoroot does work - have to wait awhile for system to reboot. When it does, need to unlock developer more again and switch usb debugging back on. I installed SuperSu through Play Store (not sure why). Backed up everything through Titanium Backup and removed all bloatware using NoBloat Free & Uninstall System App. Still find the tablet sluggish though. Contemplating CM12 not sure what gen the Archos 101b is though. Any idea?
I've unbrick my tablet empty cache and data from recovery menu, but the tablet is limited like in a demo mode: no settings menu.You can download firmware 101b platinum from here update.archos.com/AFMv1/storage//files/full/ac101bpl/20140812.191729/update-allwinner.zip
Then copy that on root sd card.
Run tablet in recovery mode vol - and power.
First clear cache then one more time cleare cache.
now start update form external memory.
Tested i have unbrick from boot loop my archos 101b platinum.
