So you do get the popup and you have accepted it (checking the box to make it persistent) and adb still says device offline? That is very strange.My apologies, I was sort-of-kind-of trying to answering ~4 people in one. I do get that popup to accept my computer's identification. I also still have the exact directory my ADB worked on my original Nexus 7 (and still works on my Galaxy Nexus). I've also downloaded the new SDK several times to try to get the most recent version, but it's still the SDK for 4.2.2.
I'm not sure what the adbkey.pub file is. Is there something I can do to try to fix permissions on this if it were the case?
I am sure it was just me who had a trouble with adb not connecting well.
After some searching found this link
Taking no credit for work. just wanted to share with everyone who has windows 8 and 8.1 not being able to connect thru adb.
Installed the first installer and it worked like a charm
Ok so after reading 11 pages of this I still am unable to still get my Nexus 7 to unlock the bootloader, it was not this hard on my HTC One using the ADB commands. I dont get what I am doing wrong downloaded and updated everything but still keeps coming back as device not found but in the windows explorer it shows the Nexus 7 is there. Help please

Whether rooting manually or using the previous version of nrt, I ran into a bootloop when rooting. To make it work I had to use beta-supersu-v2.52. I'm assuming the SuperSU (2.46) nrt was using was casing that issue. Anyone else have that issue or know for sure?

adb reboot bootloader
fastboot oem unlock
My dumbass flashed TWRP for Grouper. Wouldn't boot, so I tried erasing the recovery in hopes it would self-restore. No dice. Can't seem to find recovery-from-boot.p either. No boot and still no custom recovery for this puppy. :crying:
Would someone be the kindest person on earth and pull & post the stock recovery...or tell me how to find and flash a back-up copy already stored on my nexus? Google hasn't even posted the img files yet. My new toy is borked and Daddy wants to play tonight!
This is going to sound dumb, but are you using a USB3.0 port or 2.0? I had this error with a 3.0 port. Changing to a 2.0 one, fixed it.I did the hard reboot it still showed the bootloader as being locked. I tried to unlock again and the exact same thing happened.
FAILED (unknown status code)
finished. total time 1.015s
When I get to the screen that says "Unlock Bootloader?", I can choose "no" and it will go back to main bootloader screen. Selecting "yes" causes the tablet to just hang.
Maybe I messed something up... any suggestions?
