I did OTA update to 4.3 of my N7 3G which was rooted and unlocked (I know now I shouldn't have done it...).
I got an error at the end of the update (when was installing radio).
Rebooted, and got stuck in the google loop...
NOW, I CAN ENTER FASTBOOT MODE, BUT THE PROBLEM IS THAT THE USB DEVICE IS NO MORE DETECTED BY THE PC (I tried Windows XP, Windows 7, Linux), so I cannot re-flash it... It's not a driver's issue, because at USB level the N7 is not even detected when connected to the PC (for instance, dmesg shows nothing in ubuntu and windows does not "beep").
Is it possible that that was corrupted only the "USB stack" of the bootloader??? I could not find a similar issue in this or other forums (??).
Is there any chance to get the USB working again?
Is there any chance to send it for repair to ASUS (I bought it one month ago) with this described symptoms and with the "unlocked" icon on power on?
Is there a payed service to flash it with JTAG?
Thanks to anyone who can give me a clue...
Same problem - updated to 4.3 OTA today, N7 not recognized as an USB device at all. Still haven't tried on a Mac but I doubt it will be any different. The device isn't detected in normal mode or fastboot

I solved by sending it to assistance. Excellent service by ASUS... I did not have to pay although the tablet was unlocked/rooted.
Andrea.
since the new update to 4.3, N7 requires authorization with your pc before you can use ADB. I had this issue and had to go into developer options and click on the 'Revoke USB debugging authorization'. when I connect it to the pc again and ran adb, my N7 then asked for authorization to allow pc access. That restore my ADB.
Also make sure you have the lastest SDK installed on your pc too.
If you can enter Fastboot via pc you certainly can reflash it.

In my case (and probably the same for Colblooded) I got stuck with the N7 NOT BOOTING and NOT DETECTED by any USB host (tried also with dmesg on linux), so there was no chance to re-flash it. The only thing I could do was to send it to Brno for repair...

you said you could boot into fastboot, did 'fastboot devices' on your pc not detect it? Does it detect it now?

That's the point: I could boot into fastboot but 'fastboot device' was not detected by the PC (so I could not re-flash it). Now if I boot into fastboot the PC correctly detects the device...
What I find very, very strange is that an OTA update to 4.3 caused the USB port to stop working!! From what I read googling around, even with a problem during a system update going to fastboot mode (on + volume down) should always allow a connection to the PC for reflashing, or, at least, you could enter APX mode (on + volume up), which is an even lower level mode that is detected by the PC with different drivers (for direct programming, but need encryption key and SW not yet available for Nexus 7).
Maybe it was just a coincidence: an USB hardware failure just before I did the OTA update, which I realized only afterwards, when I needed USB for reflashing...
However the ASUS Service Repair Report states:
Problem/Symptoms: Pad Battery can't be charged. OS ERROR
Replaced Part:
ME370TG BAT COSLI-POLY FPAC
ME370TG MAIN_BD.1G/T30L/NFC
The first one looks the battery (????)
The second sounds like the mainboard...

Hello.
I recently installed the 4.3 ota update. I knew I would have to reroot. After the update I have tried everything I can think of to flash a new recovery or bootloader or anything. All without success. Fastboot simply says "Sending...", the phone says "downloading..." and that's the end of it. They would both sit in that state forever if I let them.
I know I'm not alone on this issue. I have searched and searched without finding a solution. Does anyone know of one?
Thanks.

1. Usb debugging enabled and bootloader unlocked?
2. Correct drivers installed, try these usb naked drivers for instance https://www.google.nl/url?sa=t&rct=...=RUlfH35SAJki_DdLfo8MeA&bvm=bv.51773540,d.Yms.
3. Used the original usb cable or tried another usb port?
4. If you type fastboot devices in fastboot mode do you see a serialnumber? The same for adb devices in adb mode?

USB debugging is enabled.
I've tried the original USB cable and others. I've tried different USB ports.
adb works fine. Fastboot recognizes my phone and prints a serial number. Fastboot even works for locking/unlocking the boot loader.
There are no "drivers" in the Linux world. Should I find someone who has a Windows system and ask to use their computer?
Thanks.

So. I solved the problem. I now feel like an idiot.
I plugged my phone into a Windows system and a nice notice popped up saying that my device could run faster if it was plugged into a USB 2.0 port. Then it dawned on me that only a few of the ports on my computer are 2.0 and that I had tried one of them previously but with an extension cable (because it's in the back and hard to reach). I unplugged the extension cable and plugged the USB cable directly into the port and all was well.
I hope that others who have had this issue find this useful.
Thank you for your help.
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?
I've had it working for a long time, then my PC quit recognizing my N7 2012 intermittently. I thought it was a buggy ROM so I tried another. Same problem, so I wiped it and flashed stock 5.0. Same problem
It doesn't recognize it at all anymore, but I can plug in my N5 and N9 and they work great. Has this happened to anyone?

Did you try reinstalling the drivers? Download official Google ADB/USB drivers and install them through Device Manager.
Yep, did all that. The same driver runs my other nexus devices fine. I wish I could remember what the Windows error message says...something like 'unplug and plug it in again, if that doesn't work then replace the device'.
Make sure you enable USB debugging on your tablet. And first time you do that and connect it to PC, it should ask you for sth like RSA fingerprint. Accept that and it should work.

I see where on a lot of replies that the tablet needs to be in USB debugging. If it's in boot loop, how can you do that? My Vista won't even recognize the tablet any more!
Ok it started working again, so I quickly downloaded the 5.1 image to flash. I got through it but now it just shows the google logo forever. I can get into the bootloader via the hardware keys, but the n7 isn't recognized as a fastboot device, so I can do nothing else with it....
What Windows tells me when I plug it in is this: "The last USB device you plugged in to this computer malfunctioned, and Windows does not recognize it"
In device manager it says this: "Unknown USB Device (Device Descriptor Request Failed)"
I can get it into recovery, but it just shows our little android friend laying on his back with a red triangle.

Try getting into Fastboot. Hold Power button to turn it off. Hold Power + Volume Down button to get to bootloader. Try using Nexus Root Toolkit when you get there or try getting into recovery and flashing something.

Why can't you get into the bootloader with the hardware keys? To get into recovery in your situation, Hold Power Button + Volume Up(for one second only) and the recovery should pop up.
I can get into the bootloader. Just can't get the device to be recognized bu the pc, so O never succeed at flashing anything.

Try using a different USB cable or port, or even try doing all this on an alternative PC.
Its the same on my laptop and desktop, all usb ports, 3 different cables...
I'm starting to think the n7's usb port is going bad perhaps.

Now My Phone Is In A Bootloop With No OS Installed. I Have The Chinese Version OP2
- Current State Of My Device: My Device Is In A Bootloop With No OS Installed, I Did Notice That My Phone Was Not Being Recognized VIA Fastboot & ADB On My PC. I Went Fastboot Mode And My Phone Is Not Being Recognized By PC, And I Went To TWRP, ADB Was Not Working And ADB Sideload Is Not Working. I Also Tried A USB OTG With A USB Drive And Still TWRP Recovery Is Not Recognizing It. How Ever When I Connect My Device To PC And Check Device Manager And Press Scan For Hard Ware Changes My Device Shows Up As "COM 1". I Also Did Try To Put My Phone Into Qualcomm Mode Trying Alot Of Key Combinations But My Phone Is Not Getting Into Qualcomm Mode Or It Just Might Be Me Since I Heard Its Tricky For The Phone To Get Into Qualcomm Mode. I Did Try One Click ADB And Fastboot Installed And Qualcomm USB Driver, Still No Luck. And I Did Try The MEGA Unbrick Guide. I Have Tried This With 3 Other Computers Which Are All Running Windows 10 And Turned Driver Signature Enforcement Off And Still No Luck, And Also A PC Running Linux Mint And Still No Luck. Please Help Me And I Will Put All Thanks On All Of Your Replies And I Really Appreciate Your Help!

- My Device Charges From The PC And Wall
- I Am Using The Official OP2 Cable
- Can Access Recovery + Fastboot
- Turns On But In A Bootloop
I think it's a bad cable... if you can get into fastboot and the PC with Windows 10 and Linux both don't see it.. cable
Not sure whats needed on windows, since I never use it....but after a fresh install of Ubuntu 16.04 a few days ago, I did have to install a few adb and fastboot packages before my devices were recognized. Do you know if the adb/fastboot packages and they're dependencies are installed on the Linux mint computer?
If yes, power off phone and plug into computer. Then start phone in fastboot mode. Open a terminal on the PC and run "adb devices" (without quotes of course) .....any output on screen?

I'm sure you been reading and seen people with the same cable as ours with the same problem.. works with charging but not adb or fastboot. But you can try to issue a command with it.. fastboot devices does sometimes come back empty.. just try to do OEM unlock for example.

My cable did used to work with adb and fastboot before, and I did unlock the bootloader with it before. I think now the cable got broken
Same issue working cable
Same issue... but my cable is working fine. I have a 2nd OP2 and tried the qualcomm connect with my cable and volume up, and worked perfect. More over, I swapped motherboards and still didnt work. I have access to twrp on the phone and I can get into fastboot. But no way to connect to my pc
Tried miui 12 and after flashing rom the twrp is gone I tried to reflash it the same way I did first but sadly when I'm on fastboot PC can't detect it. also tried it with other softwares but same result. Device is fine and responds when open but not in fastboot mode. Currently running miui 11 .0.6 China stable. Stucked. Also all drivers are updated
Same here.
I accidentally flashed china stable 11.0.4 zip rom on my global device through twrp and upon booting up twrp was gone and when i plug in usb the pc doesn't detect anything. In order to make pc detect the phone via usb cable i have to reboot phone while plugging usb to laptop that way file transfer option shows up in laptop and adb works but fastboot doesn't work i can force boot to fastboot through adb but upon booting to fastboot the pc stucks at waiting for device. All the drivers are installed
Currently on china stable 11.0.6
Same issue indeed
That's exactly what's happening right now. I hope someone can help us
Quote me if u find any luck.
Same issues
That happens me sometimes. I only reboot the device into fastboot again, reboot the computer, and that it. This may change depending on your computer CPU, mine is AMD. And ussually I have to use a 2.0 USB or if it still does not work a USB 2.0 hub. I know the hub thing is strange but it worked for me when my pc does not detect the phone in fastboot. Hope it helps .
With my PC I have to open device manager, look for the device, usually has a yellow sign next to it. Right click on the device name, click update driver, click browse my computer for driver software, click let me pick from a list of available drivers on my computer and pick mtp USB device. Then I read it. I hope this helps.

I use a usb hub that is very old i guess, as it uses MiniUSB. By the way with multiple computer it should work, your error is very strange, I never saw it. A thing that may work is trying to use fastboot on a Linux system (no, with VMs no). So if you can flash a pen drive with a Ubuntu ISO or any linux distro, boot linux,install fastboot and check if it detects your phone.

Even file transfer option doesn't show up if i connect my phone via usb to laptop.
In order to make pc show file transfer option i have to reboot phone while connecting the phone to pc so.
That way i can use adb but as soon as i boot to fastboot via cmd pc doesn't detect the fastboot mode.
