After some use & abuse by our students one of Mikrotik hAP ac stopped networiking. After some soldering and serial connection by USB adaptor I got following output:
OpenWrt kernel loader for AR7XXX/AR9XXX

Decompressing kernel... failed, data error!
System halted!
Any ideas how to repair the firmware?
Thanks
