I Have XT 1058 device and I've got same WiFI issues(4.4.2). In my /persist folder have:
The problem is, the last 2 files in the list, have a size of 0.00 B
I Have replaced them with the files provided from samwathegreat(and following the -rw-r--r-- permissions), but when i restart or shutdown, the files appears as if i havenīt done any change (0.00 B Size again)
I also replace WCNSS Files(except cfg.dat and cfg.ini) on system/etc/firmware/wlan/prima with the ones provided, 3 of them had 0.00 Size, but fortunately the changes persists after reboots or shuwtdown.
I'll really appreciate your help, sorry for my awfull english
