Hi guys,

I've rooted my phone before and installed custom roms so not a complete noob but not far off. Anyway, down to my problems.

I bought phone off a guy, cheap. M8 running stock 5.0.1. Didn't get to look over phone properly, all looked ok. Then I noticed the problems.

Camera working but wont take pictures, says insert an sd card before using camera.
Cannot take screenshot as says no storage available (phone and sd card empty almost)
Can sign into my Google account, use gmail, photos, music but not hangouts or playstore. They will not load.
Cannot download apk's or zip files through chrome browser, so cannot get a file manager
Baseband, imei and kernel look ok but Seial number is some weird mix of characters and pictures, like <]#~q?/

Recovery is installed and phone is S-off. Computer recognizes phone but cannot see adb devices. This means I cannot change modelid from this weird serial number.

What would you guys recommend? Backup and install a sense rom through recovery? I have a feeling that will not work because of the serial no/modelid issues.

Any help would be greatly appreciated, I am broke now with a semi useless phone!!

Cheers guys
