I have an Ascend Y300 that is 2 months old and brought unlocked from carphone warehouse in UK for £39.99 ($65-70) it ran the B175 firmware.
I unlocked the boot loader via unlock app and rooted per instructions here.....
Ive been running various custom roms over the past few weeks mostly android 4.4.2 kitkat based rims.
I Ran into WiFi issues with no or little connection and tried to return to stock via dload method.
I'm now on B195 firmware but my Y300 isn't recognised by the boot loader app and I can't tell if the boot loader is locked/unlocked or anything else.
I would prefer to return to custom ROM and recovery as this newer firmware is slow, and I hate the stock recovery.
After going back to stock, I still have an unreliable WiFi that I was advised updating my firmware would cure.
Any advise/help is much appreciated.
