Hi,
I. Have gotten myself into quit a frustrating situation. My nexus 7 was unlocked, rooted and had several different custom roms installed at various times and had never had a problem. But then one time in particular, when trying to flash a rom (which I can't even remember which one it was,) after the rom had "successfully" been flashed, it rebooted to the splash screen, which it stayed at for a very long time; before just turning into a series of flashing vertical lines that never end. I can use the power+vol- method to get to fastboot, but not recovery; it would appear that my recovery has been wiped as I get the same google splash screen loop as when I try to boot. My problem is that nothing I do allows me to successfully connect the device to my pc (w7, 32bit.)
I have uninstalled any conflicting drivers, un/re-installed the proper drivers from like 7 different guides, I have also tried two different nexus root toolkits. I even tried to use a Linux machine to no avail. I have switched USB cables, everything I have tried has not worked. This is by no means my first foray into android devices, I even freshly installed my android SDK and still my computer just fails to recognize the nexus 7 in fastboot mode.
Any tips or advice would be a godsend. Thanks.
This sounds like a issue a few people have been having.. As far as i know as of a week ago there is no solution . You need to flash the boot-loader it sounds like. There is a thread about this. Search for NV FLASH .. OR APX MODE. Sorry for being lazy and not looking for the thread for you..
They may have some things in that thread that you have not tried.
Turn your Nexus off and plug it into your computer. Does your Nexus start charging? A completely bricked Nexus wouldn't charge. If it starts charging, then try turning it on into Fastboot mode.
Sorry, I'm no dev. Just a random thought to try. But if your Nexus can charge you shouldn't be fully bricked, hopefully. At least this is what I think.
When you say your computer fails to recognise the device...
If you open your device manager in Windows and then plug in the nexus 7 in fastboot mode, what happens? Does it show up in the device manager in any category? Even with a yellow exclamation mark or as unknown device?

My bro bricked his N7
He was rooted and unlocked, flashed a rom now it bootloops on the logo. Now when doing adb devices, it doesnt detect the device when in bootloader, went to device manager and shows problem with driver. Tried other drivers but says its up to date. Thing is I just upgared his friends N7 with the same drivers so I know thats not a problem.
It wont go into recovery either. Now when it is bootlooping, the decive is recognised when doing adb devices. So can I flash a factory image when it is bootlooping or does it have to be in fastboot?
TRY THIS
from powered down,
hold VOL- and POWER for ten seconds,. then let go of POWER and still hold down VOL-

Just goes to bootloader?
Edit seems to be working now even though when doing adb devices in fastboot it doesnt list the device id
In fatboot mode you don't have adb access - down load a recovery image and name recovery.img
Hold shift and right click in the folder recovery.img is in
Choose open command here, in cmd type
fastboot devices
If you see your serial number proceed
fastboot flash recovery recovery.img
When finished reboot to recovery and flash rom of choice
ps, you have had to either change your path in enviromental variables to include platform-tools from the sdk or have both fastboot.exe and recovery.img in the same folder that cmd is pointed to

I had CM 10.2 on my LG G2 but I wanted to give it to a friend so I thought I'd better remove the root for warranty reasons. I removed it with this method(D802): http://forum.xda-developers.com/showthread.php?t=2432476
After flashing it stucks on the LG logo. I tried to get into recovery by holding Vol down + Power but it turns off and the LED begins to blink red. After that I used "Upgrade Recovery" with the LG mobile support tool. Now my branding(hutchinson 3) is back but it still stucks and I still can't get into recovery.
I've now been looking for 6 hours for any solutions but nothing seems to be working so far. I hope you can help me.
try vol dwn+pwr until the LG logo shows up, let go and press and hold them again
It boots up to the 3 Branding then and the bootloop keeps on going.
The uota
Connect it to your PC and use ADB to reset it
ADB can't find my device
edit: It must be a driver problem, "lge android net mtp device" cannot be installed for some reason. I re-downloaded and installed the drivers, restarted my comp and "lge android net mtp device" is still not working.
Volume up to enter download mode while inserting USB. Will install drivers. If not, extract drivers, point module from device manager to folder. If still no, try koush's universals. Flash stock. You may not have a recovery left after looping with kdz.

It says driver is already installed, but it isn't.
So uninstall, reconnect, force them.

Device manager - property of MTP device

Phone needs to be in download mode. It should trigger other drivers, not just mtp. Try another computer...
Um.
Try do this

You can also try to install pdanet and check with that. Select the device and proceed. Once the drivers are installed .. Try flashing the stock... Lemme know of this works

Hi All,
I bought a Nexus 4 on eBay thinking I could fix it but I am really struggling.
The nexus 4 has TWRP 2.8.6.0 but that is all.
I cannot enable USB debugging as I don't have any rom installed.
I have tried a USB OTG cable with power, but have learned that the phone still cannot output the right power? The light on my usb stick comes on but TWRP does not list any USB OTG.
This phone does not have an SD card slot, so I cannot load anthing this way.
Is it impossible to get this phone working?
Kind Regards,

Have a look at this thread ..
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
(Read the thread thoroughly, and take notes, its real easy to get lost in the middle of the procedure and mess it up, and having to start again).
Flashing the stock rom is done entirely via fastboot, so you shouldnt need to worry about adb.
If you can boot into bootloader you should be able to flash stock image, once you get the windows drivers sorted. Luckily I'm on a Mac, so drivers haven't been an issue. I had a similar scenario sometime ago, and after flashing stock, all was good in the world again. I may be wrong, but you'll probably need the latest platform-tools (which contains fastboot) if you're flashing the latest stock images. (Someone correct me if I'm wrong on that one).

This is good information, but I cannot get any further that plugging the phone into the PC, I have tried 4 different usb cables and with them all windows 7 and XP says "unknown device".
I wasn't sent the original cable from the owner which I am asking to do if they have it, but it may be a long shot for them to still have it.
Looks like I need the original usb cable?

I don't think the cable needs to be original, I've used a Motorola cable on my N4 to flash stock, with no problems.
Is the phone in fastboot mode when you connect to pc?
Have you tried these drivers?

For information I am using a cable from a usb cable that came from a Nexus 5.
When the phone is connected to the PC it had an android lying down with an open chest.
When pointing to the android developer sdk drivers as above it does it's usual thing of saying it is already up to date below that still saying unknown device. I'm so frustrated right now.

Can you reboot to the main bootloader screen?
The reason i ask is .. When you see the android lying down is there a list below showing the phone stats? If not, possibly this is why windows is reporting an unknown device.
You should try to get back into fastboot
This has the info to get to bootloader if youre not sure how..

Underneath the android lying down it has:

CARRIER INFO
SERIAL NUMBER

LOCK STATE (in red text - unlocked)
Above the android lying down I can use the hardware buttons to toggle between "Start | Restart bootloader | Recovery mode | Power off"

Sounds like youre in the right mode. The problem would likely be on the pc/driver side.
P.S. in fastboot mode, you only need to use fastboot on pc .

The driver issue is a massive stumbling block.
I'm still not sure if the cable will work.
I understand I can use fastboot after the PC recognises the nexus 4.
I have a Lubuntu PC this may help me but I have no idea where to start in terms of the drivers.

I use a mac, so im no use when it comes to linux variants etc.
Depending on the power of your pc, you could try using a virtual machine (i.e. virtualbox running windows xp if you have xp disk, or even windows 7). Ive done this before on the mac (xp virtual machine) and it works. This way you can install the correct drivers on a fresh install of windows, without messing with the host OS.
Otherwise, best bet is to uninstall any drivers in your current windows, and install divers from google link i posted earlier.

just outta curiosity, when you plug the phone in (in bootloader mode) change dir to the one with fastboot.exe in and type (in command prompt):
fastboot devices
what output do you get?

Just to check I am doing it correctly, I launch cmd in windows, change the directory to the location where fastboot is and type "fastboot devices". The result of this is it just gives the directory name again waiting for another command.
I hope I'm not coming across as ungrateful, I assure you this is not the case.
I tried rooting my G2 using this guide, and seem to have f'ed up somehow.
The phone now won't boot (stuck at the "LG" screen, with rainbow LED), and I can't get into download mode.
The strange thing is that I do get into recovery mode, but it seems to exit abruptly. When I try to recover (by selecting yes twice), the Android recovery icon shows up for a couple of seconds, but then it goes back to the "LG" boot screen again.
I would be grateful for any help.
I've tried connecting to a computer with Ubuntu, as per this guide: http://forum.xda-developers.com/showthread.php?t=2582142, but I was unable to mount the phone.
It does show up in the device manager in Windows, under "Portable Devices".
I've disovered that the guide I followed for rooting was for G3 phones (and the G2 D805). I'm guessing this could be part of my problem.
But the guide said that I should be safe, since I had Lollipop. The Download mode should be able to save me if anything went wrong. But alas.
Before starting the rooting process I had the latest Lollipop update from LG (it was performing poorly, that's why I wanted to install a custom ROM).
Is it possible to save this phone? I'll probably look for a good deal on the 5X at Black Friday if I can't fix the G2, but I'd rather keep this phone working for a while anyway.
Still having trouble with this.
If I turn on the phone and connect it to a PC (with the phone stuck at the "LG" screen) it appears my the device manager on my PC, but adb.exe reports no connected devices.

How do I install these? When I plug in the phone and view properties in device manager, I can't select update or uninstall driver.
(I would insert a screenshot here, but I need to have more posts on the forum first)
EDIT: I just removed the LG drivers by uninstalling the LG software + drivers, and removing any left over drivers using Nirsoft USBDeview. Then I installed Koush’s Universal ADB Driver. But adb still reports no connected devices... I guess this device is bricked after all.
