[Fix] No Wifi- Wrong Date& Time (SHOWING YEAR 1970 ) -No Carrier - No Signal -No GPS

Hey Guys,

I know this method is floating around the OPO forums under different descriptions - but it takes a little searching to figure out and has a bit more info and steps.,

Anyways I am very grateful to all developers that have contributed to these kinds of fixes such as [MENTION=5098295]markbencze[/MENTION] here is his thread http://xdaforums.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061

Often after flashing a new kernel or reset or restoring my Nandroid via TWRP I lose my (T-MOBILE)Carrier and WIFI ,GPS , Time and Date (1970) caused by a corrupted Persist(How it gets corrupted I have no-idea)-BUG?? .So here is the fix that works for me .This works without having to reflash Factory and the headache that comes with it besides it will not fix these particular issues.

here is the procedure I have used and WORKS EVERYTIME!

Please remeber that no-one mentioned in this thread is to blame (except maybe yourself) if you dont follow the commands and instructions correctly .It is a safe procedure but you never know!!

First you will need the files below!put in same directory you have your ADB/Fastboot files in on your PC:

( IMO,If you dont know what this means then maybe you shouldnt be doing this..)maybe read this first::http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378

Anyways get into Fastboot mode (bootloader) and

From your PC

type

:

fastboot erase persist

Now type:

(make sure you have these files below in the ADB/Fastboot folder where you are running these commands)

fastboot flash persist persist.img

then type:

fastboot reboot

If unable to connect to your computer via Fastboot you might need to download the usb drivers to your pc!

(these can be found in the OPO toolkit amongst other places)

I was Recently told that this step is nolonger needed

thanks [MENTION=5098295]markbencze[/MENTION]

(with keywords such as No Time and Date etc.).I know and realize that there is posts and threads that address this issue.but the threads and titles are under different dscriptions which makes it difficult to find for some .
