Need root without computer, bootloader unlocked...
I have checked at least hundred threads now, but my problem seems unique! (First time this happened to me
When I connect my N7 (WiFi, 32 GB) to my laptop (Win 8.1), it says "USB device not recognized - The last USB device you connected to this computer malfunctioned, and Windows does not recognize it."
In Device Manager, it is like the image attached, no other recognition for the device. Upon selecting Properties, It says "Code 43"
in status, also says "A request for the device descriptor failed"
. That happened with 2 computers; I used 2 cables (both worked previously). So it means N7's USB port is somehow malfunctioning. But it gets charged as well as ever!!
This started after I tried an OTA update of 4.4 earlier (the download had not completed, but a prior small update (1-3 MB) was installed).
Now, I have Android SDK (latest version) and installed those google USB driver and platform-tools. I have NRT 1.7.9 (which worked for me previously). But I cant get my N7 to answer to ADB requests. Upon connecting USB, it says "Charging (USB)" but no option regarding PTP or MTP appears.
I have developer tools installed. I followed the instructions given in NRT about ADB installation to the letter but still no progress. I have tried a factory reset too.
BTW, I dont have a custom recovery flashed. It vanished along with the precious root privilage.
Now the N7 is in Android 4.3 (JWR66Y), bootloader is unlocked, SuperSU is Installed (but do not work due to having no root access and I cant even Uninstall it for the same reasons!!!). Now the OTA update also do not work mysteriously (it downloaded the 4.4.2 update and went on to install it, but as the bar started filling, it only said "error" and stopped!!! no explanations whatsoever!!!!). I will be very happy any of the followings:
1. root without computer (wireless ADB is also welcome),
2. working OTA, or anyhow the 4.4.2 update
3. working ADB connection with my laptop.
Any help will be very helpful... Thank you in advance...
