Is it possible to re-root my nexus without needing a usb cable, i.e. could i use something like airdroid to get the files onto my device?? my phone is not being recognised by my computer, it charges fine though. usb hosts diagnostics thinks there might be an issue with my firmware and could be fixable with root. My device was rooted until 4.4, which of course uprooted it. problem seems to have happened about then but I dont know how to reroot without a cable, if its even possible...
hoping for some magical answer here guys
Thanks

You can use Wireless ADB (enable Debug mode and send commands through Wireless)

EDIT: Can't send external links.. search "ADB Wireless (no-root)" in Google Play Store

Just rooted using this method:
http://forum.xda-developers.com/showthread.php?t=723479
When I hook up the USB cable, it no longer shows up on the phone and gives me the option to mount memory card.
How do I go about fixing that?
(and also, should I need to, how do I unroot?)
EDIT - Now works after reapplying USB settings, weird.
Re Root the phone with one click. If you cannot mount to the computer etc. then odin back to stock and then reroot, You are not the first person to use this rooting and have this happen. Not sure why may be just a batch of phones this method doesn't work with.......
I had the same problem and solved it by allowing USB Debugging mode. When you use ROM Manager and CWR, it actually tells you to leave the phone in the USB Debug mode, maybe the connections issue is the reason?
I am having problems with my N7 not connecting to my desktop. I can get into bootloader and recovery but I can not mount USB to add a rom. I'm SOL as of right now and have no clue what to do...

Could it be related to this issue:

If you have plugged your Nexus 7 on a car charger, the usb might be dead and only be used for charging (and so unable to transfer new ROM data).
charging is fine...is it possible that I did not enable usb debugging before i wiped to factory reset that it would prevent me from connecting???
alright heres alil update i tried using WUGS toolkit and trying to unroot everything was going fine until it cannot find the flashstock.bat...now im back to square one. i cant find the flashstock.bat anywhere
I was having the same problem. It would see the camera mode, but not the mtp. I read in another thread to turn off debugging in settings. What do you know. It worked! Computer sees the tablet now just fine.:victory:
My set cannot be connected by usb so I tried to use adbwireless. Managed to get connected and device put online. However after putting the device in bootloader, I lose connection because it kept saying < waiting for device > in the command line without any action taking place. I need to unroot my device to send it back to Asus. The usb problem and the speakers went kaput too!
Anyone with experience in adbwireless so that I can do the work through it. I tried to google for more info but only the same..
Thanks

fastboot and adb are not the same thing.
You will never be able to communicate with the bootloader (for instance to lock the bootloader) via adb - or via any networking for that matter.
If you think the reason your USB port is not working is due to mechanical damage your best bet is to replace the small sub-assembly that has the USB connector and the headphone jack . See the iFixit teardown of the N7.
By building your own variant of a Stock ROM installer it would be possible to flash a stock ROM and stock recovery in one pass; but to lock the bootloader requires the tablet to be in fastboot mode, and afaik there is no networking possible in that mode using publicly disclosed methods.
Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.
Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.
Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.
So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.
I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.
The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.
Thanks
Before you updated when was the last time you connected your N7 to your computer?
When you connect your N7 to your computer does it act like it is charging? Have you tried more than one computer? I had a similar problem with mine last year & sent it in 3 times. Asus replaced both the USB port board & the main board on different occassions. I suspect your mainboard might be faulty.
Does adb see the device

I last connected the nexus to the laptop a few monts back to load some music onto it, didn't have a problem. It's only been connected to a computer maybe 3 times. once to root/rom it then another few times to load music etc.
I can't see why the usb board maybe faulty as i can read data from a usb key when the otg cable is connected.
It's a strange one. You could be right, i might try pick up a broken nexus and swap some parts. Usb board etc.

Yes adb is shown in device manager, but it's not recognizing the nexus, comes up with an error 10 , cannot start. etc etc

I am having this same problem on my (unrooted) HTC One after attempting to "convert" it from an AT&T to a Google Play Edition device with the procedure described here.
As part of the procedure, I attempted to flash the stock Google Play Edition ROM using fastboot commands, but I got an error message. The instructions say to just try the flash again, but the phone no longer connects properly via USB (error 10) while in bootloader mode. While in bootloader mode, the phone indicates there is some sort of problem (a line showing the OS version is highlighted in red), and attempting to enter recovery mode does nothing but display a phone with a big red X in it. The phone seems to operate fine and responds to ADB commands when the phone is fully booted, albeit with the old OS (not Google Play Edition) still in place.
Any Android device could theoretically get in this state. We're sort of "paralyzed", because everything we want to do to regain control of the bootloader and fix the situation seems to require issuing fastboot commands from a computer connected to the phone while it's in bootloader mode. Yet entering recovery mode or getting a computer to connect to it via USB no longer seems possible.
I wonder if there's another way to issue fastboot commands without relying on the USB connection to a computer?
Okay so i have a nexus 7 right? yes, but im fairly custom to rooting and all that stuff. Well im not a nub at this stuff but i need help once in a while XD, i just got the thing to turn on again i let it die completely and the charging bug decided that it wouldn't charge. I ended up jump starting the battery and now it turns on but now i plug it in it turns on right? yes it does but now i can get access to any data thats on it. (P.S there isnt any data on it since i had to wipe cyanogenmod 6.0.1 off it) and theres only twrp recovery on the tablet, i can access twrp and the boot loader (unlocked obviously) but i cant access fast boot or push files via adb. The charging port is still good on it i know that we had it tested on a friends tablet and it worked fine. OTG usb doesn't work either i cant seem to get data on the tablet but it turns on when i plug it in, it doesnt charge when plugged into a wall adapter or a pc it just turns on when plugged into a pc. Any and all info is appreciated. (sorry for my spelling errors if there is any, also i am on linux so i dont need drivers as far as i know, i also tried on windows and its a no go the device doesnt show up on either os)
nexus 7 2012 btw

Eh just dont bother guys im pretty sure its dead, the nexus help forums didnt have anything.

Thanks for the help but sadly ive tried that...
As the device can go into fastboot and twrp with adb and otg without data transfer being possible I'd say most likely the port is broken.
Just to be sure no adb or fastboot commands work at all right? even those which don't transfer files. If they work then your partition layout is messed up which could be fixed

Did you try to charge the N7 via wall adpater or the pc? Did you use the genuine charger that comes with the device? What does it look like when you plug it into your pc? Did it show up as a mtp device (or any kind of device) ?
Try charging the N7 with genuine charger, or via pc. Make sure you install the driver for the N7 (go google it) before plugging in. Judging by your status, it appears that you're having a defective charging port or mainboard. Usually you'll end up sending it to the manufacturer to get them replaced (hope that it won't happen :3 ).
Have you used the push files and adb function on TWRP? To the best of my knowledge, these errors don't come about often in TWRP. If you don't know to use it, look it up on Google or the Xda threads. One more thing, losing fastboot is pretty rare with N7, so if you're not sure whether the fastboot is VANISHED, go to this link: http://forums.androidcentral.com/go...1477-guide-nexus-7-factory-image-restore.html
You can contact me for more insight if all that doesn't satisfy you: [email protected]
Glad that I could help.
