[Q] 'No OS installed! Are you sure you want to boot?' How to reinstall android os?
I dont know much about this stuff (def not tech savvy), but I decided to take my bad esn Sprint HTC One (running 4.3) and try to unlock it myself. I was successful in unlocking the bootloader, and I even rooted the device on my own (woo!!!). I was on the last stage of finally unlocking the phone, so I decided to go for it.
I tried to follow these steps to finally unlock my HTC One, but I did not know how to go to /system/app to replace the files (The 'Root Reader' app didn't show /system/app in my phone).
The files were:
As a result, I tried to flash the copy files mentioned previously using this video as a guide
I dragged and dropped the copies into the 'system storage' (not into a specific file) and started wiping data in TWRP 2.6 (Im assuming I wiped something that I shouldnt have). However, now whenever I try to boot my HTC One out of TWRP, I get the 'No OS installed..." message and it just just keeps showing the white screen with the HTC logo when I do boot anyways. When I connect my HTC One to my PC via usb cable, it doesnt even show up. I decided to take a screen shot of my files/drives/etc that I used. When I click on the 'instal' button in TWRP, it no longer shows the 'android' folder while scrolling through the list of things. My phone also automatically shuts off when leaving it on idle (TWRP running) for a bit, it doesnt connect to my PC anymore too
What should I do to get the phone working again? Could I unlock it from here or do I have to backtrack or something? I have very little knowledge about this stuff so please try to explain things easily for me lol
