I rooted my Nexus 5 with the Towelroot app. Everything went perfectly fine (I had to do a recovery, but after that, Nexus running smooth and it was rooted.
Then I decided to try something stupid. Alter the Nfcnci.apk so that the NFC TAG scanning app was silent instead of the end.ogg noise when scanning a NFC tag.
It all went wrong when I merged the unpacked .apk files back into a .rar and convert it to a .apk with "formatter" program.
When I tried to put the NfcNci.apk app back in the system/app folder with authorisation 664 it didn't work anymore. the stock app crashed.
The nfc part of my phone wasn't working anymore ! (when opening NFC tools, i got a NFC ERROR message... apparently, i did something wrong when trying to replace the app with my modded version)
So i did the most stupid thing I could have done: instead of putting the original NfcNci.apk file back into the system/app folder I did a hard reset recovery (go into Recovery mode, wipe data)............
Now, with my freshly recovered nexus 5..... I CAN'T GO INTO SETTINGS to turn on USB debugging (because I clearly wanted to put the original 4.4.3 image back on my phone)
so i'm stuck with a phone that :
1) is rooted.
2) doesn't go into settings so I can't turn on USB debugging
3) doesn't go onto the app store because i can't link my google account because i can't go into Settings.
4) is actualy a dumbphone now. The only thing I can do is use stock apps and call and text someone.
Could someone PLEASE put me out of my misery?
i'm litteraly crying here. I had this phone for 2 weeks.....
I want to unroot the damn thing and go back to the way it was....
