Semi-Bricked....can you help?

Hi, been lurking around here for a good while now....fantastic website website and I've learned so much but now I have an issue.
For what ever reason my nexus 7 will not boot, I can get into fastboot and have been following the guides to do a full factory restore through fastboot. Everything goes fine until is comes to "Sending System" then just.....stops. I have used the nexus toolkit and also the official sdk drivers and fastboot contained there. I only have an old laptop as my main pc for some reason does not recognise the nexus.
I have tried alternative USB cable too.
Does anyone have any other advice.
Also the device is complete stock no custom rom has been installed so no custom recovery available.
I really appreciate any help.
Cheers!

Okay well ive managed to get it back alive!
used a new laptop and usb cable and it all seems to be fine now!
Now back to my original issue...windows 8 is pissing me around and wont recognise the bloody thing!
Any ideas?

Try a search, shouldn't be hard to find what others have done with Windows 8 difficulties...

Go to Device Manager, show hidden devices and uninstall any Android or ADB related devices that you have. Disable USB debugging on your Nexus, then plug it into your PC and see if it's recognized. If it is, then re- enable USB debugging, then go to Device Manager and reinstall the Google USB drivers to get ADB support back.

Thanks for the advice, first thing I did was try searching....I have tried countless methods suggested but nothing works its like windows cant find the drivers. In the device manger its recognised but no diver installs no matter what I do. If I force the manual driver install it fails!? I have tried the Naked drivers, the SDK even making sure the media components of windows are installed properly

KitKat on Nexus 7 Failes

My problem is basically getting my nexus 7 to connect to the pc... This is what I've done. and what happends...
When I first connected it, I got no message at all, and nothing happened, then I changed the cables around, I changed the USB Pports... and by some mysterious wounder I found a combo of pad, port and cable that made my nexus go your connected as MEdia Device... BUT my computer wont see it.. hmm.. changed it to camera mode, and still nothing. Then I turned off USB Debug. Still nothing, but wen I turned it back on, I got the message that I was connected, and I got to install some drivers, and NExus popped up as a camera in windows 8... Started up the nexus toolkit thingy (I love simplicity) And there it popped up.. rebooted to fastboot, and no luck... windows wont recognize the damn driver. And I have done everything I can think of except install linux and try it there... IT wont connect in Fastboot mode, Not a chance... I've tried to unindatll all the drivers, and their files. everything I can think of... I've followed like 20 diffrendt howto s on the same problem, and no luck...
So how would a guy like me go about doing this in linux... is there a tool made for it? Do I need to do it all by commands? Is there a howto?

In my win8 64bit the nexus 7(2012) does show up as a portable device, but MTP works and there's no issue with sending or pulling files. currently it's running stock kitkat 4.4 (KRT16S).
like you I suspect it's a driver issue with windows. If you could locate the device on device manager (try View\Devices by connection and look under PCI Express Root Complex and comb for USB Host Controller\USB Root Hub\Generic USB Hub), delete the entry for Nexus7 and scan for hardware changes again. This forces the system to look for correct driver(s) for your nexus.
Some guides on updating drivers are in fact concerned with the ADB interface, which is needed for USB debugging. In your case, if it's just accessing the internal storage of your Nexus you want to solve, those info may not be relevant.

Basically I would like to have ¤.¤ installed on my Tablet. Right now I have 4.2.2 SmoothROM installed, and whilst this works for me, I'd like to get the update.
In the past, I used the Toolkit to root and install stuffies... Until the last update to SmoothROM wheres I used GooManager thingy...
When I started this I got the Tablets to connect using PTP whilest in Android, but not in Fastboot mode. So I downloaded the 4.4.kitkat Offisial ROM and tried to install that in recovery, after a full wipe, BUT that ended in me having to install SmoothROM again. And now the Tablet wont connect at all... I have deleted all drives, and reinstalled them... I've tried 3 diffrent Wondows USB driver, but no luck there... I've tried like 5 diffrent USB data cables, in all 4 of my USB ports, on 2 diffrent machines, both win 7 and win 8... AND still no luck... now all the machine says that it cannot identfy the device...
Tomorrow, I will end up installing linux, and try there... At the moment I loathe all things called windows drivers...!!!!
EDIT:
Great news... I found a cable, I havent used in a long time. THis is the original cable that came with the Nexus, and I havent used it in a long time because it had some bad connections. Felt like the plug was loose, but now it made the whole thing work without any problems at all...
So I found the cable, used USBDeView to delete all drivers assossiated with the nexus. plugged it in while in fastboot, and BANG installed. rebooted it, and BANG installed.

[Q] Bricked Updating to CM11

Hey guys any help or suggestions will be greatly appreciated on this matter. I will try to be as detailed as possible but I'm trying to fix this phone for a friend and he isn't very phone savvy. From what I understand, he was previously on CM10 and tried updating to CM11 using the cmupdater. For some reason it failed and he was stuck in TWRP. When he tried to reboot it kept kicking him back to recovery. He took his phone to a phone repair shop who then wiped his device. At this point he gave me the phone to try to fix.
First of all I have working fastboot and adb drivers for my Nexus 5 so I don't think this is a driver issue but I'm no expert on the Nexus 4 so I could be wrong. I'm also running Windows 8.1 if this is any relevance.
I can still access the devices bootloader (ver MAKOZ20i)
I can still access TWRP (ver 2.6.0.0)
When plugging the device into my USB 2.0 ports, nothing shows up in my device manager in bootloader, TWRP, or TWRP ADB sideload.
When plugging the device into my USB 3.0 ports, I see 'Unknown USB Device (Device Descriptor Request Failed)' and the Device Instance Path is 'USB\VID_0000&PID_0002\7&20F39B9B&0&2' in bootloader, TWRP, or TWRP ADB sideload.
I've never heard of a device not being seen at all in by USB 2.0 ports but showing using USB 3.0 ports so I attempted to give extra juice to the phone using a powered USB OTG cable. Still nothing shows up.
I've tried running 'fastboot device' and 'adb devices' with no luck.
I think I've covered all the bases... can anyone think of anything that could help me re-install a new rom or factory reset or his he out of luck?

I think it may be a Win8 problem. You have access to another machine with Win7 or WinXP?

Install "universal driver.exe" in win7, than connect phone while power off, I think it'll install driver...than push any custom ROM to phone via adb or just flash any official IMG..

Well I can tell you WHY it didn't work. That version of TWRP is not able to install 4.4 (CM11). if you manage to successfully push via adb and get it started again, make sure to flash the newest version of TWRP before trying that again.

Thanks for the reply guys. I kind of guessed that the version of TWRP was not compatible as I installed CM11 on my old Nook Tablet and had to update my recovery before installing it. Unfortunately the guys who wiped the phone prevented me from installing an old version of CM10 that my friend probably had from the cmupdater.
As for Windows 8 being the issue.. I attempted to try to use my laptop which runs Windows 7 but was unable to get anything to happen. Since the laptop only had USB 2.0 ports, plugging in the device to any of the ports did the exact same thing as what it did on my desktop (Windows doesn't even recognize anything is connected). I still get the charge animation on the phone but yea... nothing in device manager. I'm thinking of running Linux from a live installation to see if anything different happens, unfortunately its been ages since I've touched Linux so this is kind of a last ditch effort here.
Any other thoughts?

One more, when you plug into usb 3.0 you can see unknown device Right ??
If yes, download driver files from here Here.
It's a zip contains .inf files, Now click on unknown device and select update drivers then give the path to these drivers manually.
Hope this will help you out.

I'm pretty convinced at this point that the phone can't be fixed by me. Running it through Ubuntu I can't see the device at all (USB 2 & 3) when running the lsusb command but it sees my nexus 5 just fine. I even tried modifying drivers to match vendor id product id and class id as reported by windows. Thanks for the suggestions. Does anyone know of a reputable service to get this phone repaired? How much does a JTAG repair usually cost?

Awesome! Didn't realize this was an option. It didn't work using the USB 3.0 ports but the USB 2.0 actually worked for this method. Thank you!

[Q] Nexus 4 gone stealth

... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?

Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426

Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.

Have you tried the file manager in twrp yet? I've found it connects when nothing else will...

N7 lost abilty to use ADB

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.
