Well to make it simple, the newest twrp is very buggy and to make a long story short i installed a new rom, and while it was restoring my data, my n7 shut off. its done this before so naturaly i held the power+volume down buttons too boot into the bootloader but it wont turn on. Any help/ suggestions?

I'm confused. It's a little off-topic, but what does "restoring my data" have to do with TWRP in the context of flashing a new ROM?
Anyway, I would proceed with a dead battery or loose battery connector hypothesis first. It's not obvious why writes to /boot, /cache, /data, or /system would affect the bootloader.
Anything is possible at a low enough probability I suppose, but you should start troubleshooting operations with the high-probability scenarios first.
For instance - with the power off, will the "charging screen" display when you plug the tab in? How about APX** mode? (Plug in to PC and start with Power+Vol-up). If you didn't see either of those, it's likely a power supply or hardware problem.
good luck
** make sure you exit APX mode by holding down the power button for at least 20 seconds. I'm not sure if it shuts itself down after an inactivity timeout - you don't want to be draining power while trying to charge the tab.

Well, you backup your data, Wipe data and cache, flash the rom, gapps, ect. then restore data, the charging screen wont dispaly, apx mode doesnt work, but the whole story: went to flash a newer version of my rom, install faills due to error in updater binary so i go to reboot and it says "No OS Installed! Are you sure you want to reboot?" i press dont reboot, go to install the older version of the rom, go to restore data and then it shut off.

The lack of APX mode or the charger screen suggests a battery problem or a hardware failure, not a software problem. APX mode will be present even if the tablet has absolutely nothing in flash memory.
Having nothing in /system (no OS or even no filesystem) will not affect bootability of either the bootloader or the recovery.
I don't know why you would wipe data only to restore it after flashing a ROM. Usually wiping cache & dalvik-cache is sufficient for "dirty-flashing" a ROM upgrade as it is very unusual for ROM installs to diddle with the /data partition. (But making full backups is always a good idea.)
I would check (carefully) to see if the battery connector came loose before you decide to throw the tablet away.
good luck

You can hold the power button for 10 seconds and wait till you see the Google logo. Then release and hold it 10 seconds again, when the screen turns off hold the volume down button and wait for it till it automatically boots again. You'll enter bootloader mode. Download wugfresh' nexus root toolkit and install it. When the program is loaded there is a flash stock option on the right side of the program. Select the soft brick / boot loop option under the flash button. While in boot loader mode connect your nexus and press the flash button.
This is all I know!

NEXUS 7 Bricked - NO OS - tried everything but...
It's a catch 22 here. I can't get drivers installed and the nexus recognized and so when it comes to flashing/restoring via cmd prompt the PC won't recognize my device and so I can go only get so far. I have no OS installed as I wiped all like an idiot in twrp so how the hell can I get drivers installed on a nexus that has no OS installed? I can't enable usb debugging etc because, well, I have no way of getting the nexus to work so can't get into the settings to do so.
I have tried everything in twrp but there is nothing to restore - i can't get roms pushed onto it - God I give up. All I need is the PC to recognize my device and I know I can crack this. What do I have to do? Please help this idiot.

USB debugging doesn't mean **** when you are in a custom recovery. It has adb already. Your problem is your computer. Fix your computer by following one of the bajillion threads and posts about the nexus 7 drivers issues.
Installing drivers does not need android to be booted.
Your best bet is to put it in fast boot mode and follow Google's own instructions to flash it back to stock.

I must admit I'm a little 'hazy' myself when it comes to ADB related issues... I've never had much cause to use ADB. (Think I've used 'adb pull' on a couple of occasions). And I've never been in the invidious position of not having a bootable Android OS on my Nexus 7 either - which does seems to happen a quite lot with TWRP users, less so with CWM users.
Anyway... just had a tinker... and you could try the following workaround... this seemed to work to for me.
----------------------
Locate the folder on your PC where you keep your FASTBOOT and ADB .exe files...
Copy whatever ROM .zip you want into this folder.
The following example uses SmoothROM-v5.0.zip ... There is nothing to stop you from renaming this to something shorter, for ease of typing later... so, in my case, just smooth.zip.
Boot your Nexus 7 into the BOOTLOADER (Vol down [hold] + Power button), and then into RECOVERY (TWRP) and hook it up your PC.
Open a command prompt window on the aforementioned folder... and type...
Code:
adb devices
...which should yield something like the following...
Code:
List of devices attached
012345679ABCDEF recovery
(If you don't see a serial number... then you definitely have a driver problem...)
Otherwise, it's just...
Code:
adb push smooth.zip /sdcard
Or whatever ROM you wish to 'push' to the emulated SD card.
This will likely take a fair few minutes for a 300Mb+ size file (typically the size of your average ROM)... on my Windows XP box it took 4 minutes (1328 KB/s, 32565894 bytes in 239.486s) to copy over. And there are no 'progress gauges' of any kind, either... So season your patience a liitle. You can always pull up another command prompt window and type adb devices again to ensure you still have an ongoing ADB connection.
Once copied over, and still in TWRP, you can just flash it.
Good luck.
Rgrds,
Ged.
Still nothing on mine. im just about to give up and wait to see if google releases the N7 second generation at the i/o
If You familiar with Linux, You can try to understand the logic of
changing the modes.
You need to run udevadm monitor in one terminal. Then press some
combinations of key/s and look for changes with usb-devices.
The better, if You run wireshark and sniff USB interface with your device.
Put attachment here, with a comments what was pressed.
since it seems to be a hardware problem, not software, im just going to send it to asus and see what they can do.
Hey guys, looking for some assistance here as I am at a complete loss.
Decided tonight to root my 4.2.2 Nexus 10 using the Nexus Rootkit v1.6.3 and the aid of a YouTube video. All went swimmingly up until the TWRP wipe. The video I followed failed the wipe attempt and the guy showed how to get the N10 out of the bootloop and do a 'wipe data/factory reset' via Recovery Mode in the Bootloader and then restart.
Problem is, my wipe never failed like his did in the video (great I thought!) and so I restarted after that and now I find my N10 booting up to the Google Logo (with the padlock at the bottom) and it just sits there. Doesn't even get to the 'X' logo which should come after.
I've tried a few things including the manual wipe data/factory reset from the bootloader and restart but everytime it gets stuck at the Google Logo. I am also now at the point where my N10 doesn't show in Device Manager as it did before. It now shows under 'Portable Devices' as a 'MTP USB Device'.
I am really at a loss here and searching various solutions is just confusing me even more and would appreciate it if someone could help me out, even just getting back to stock for now. That's if it isn't goosed?
Thanks in advance
Have you tried using a different usb port on the PC, and rebooting the PC?

I have yeah. Left my PC off overnight and went back to it again this morning and same issue.
Plug it into the PC (this time using a USB port on the back) and it initially comes up 'installing device driver software' quickly followed by 'device driver software was not installed successfully', quickly followed by 'installing device driver software' again and that's when it shows up in Device Manager as 'MTP USB Device' under Portable Devices, whereas before during the root attempt it was show as 'Nexus 10'.
When I first read the subject line I thought it was "another one of these" where OP hadn't searched on the existing boards. But when I read OP I see you did try "the usual suggestions". Hoping a more seasoned pro jumps in here to help...
I can say that on the handful of "really bad" posts like this that I've seen they usually end with the person saying something like "well I don't know what happened I just kept trying all the power button / charge recommendations and finally it worked" - so don't underestimate the effectiveness of repeatedly trying it like a mad man!
Some random suggestions I have that may help:
-Can you leave it on, on the Google screen, to where the battery 100% drains, maybe this could act as a "battery pull"
-Try a different USB cord
-Try rebooting it via the power buttons while the device is plugged into the wall charger
-Download the Android SDK, then use its "update manager" to update its USB drivers to today's definitions
-Try another PC
Good luck!
Thanks for the suggestions bigmatty, I'll certainly give them a go when I get in later.
I think my biggest concern is that there doesn't seem to be any OS on it, possibly to do with the wipe during TWRP and then I rebooted - was I supposed to reboot at that stage? That's where I got into this loop. And now it doesn't detect it as 'Nexus 10' in my Device Manager on my main PC. Only this MTP USB Device - sometimes showing a conflict warning triangle, sometimes not and no longer showing as a storage device in My Computer.
I did connect it to my Netbook (Running XP) earlier and it detected it as an 'Android Device' under Other Devices in Device Manager. Tried installing it with the naked drivers on the Android SDK and it now lists it under 'Android Device' in my Netbook's Device Manager as a 'ADB Device' (I think, would need to double check as I'm not on it at the moment.)
I just want to find some way of getting it back to factory settings and stock OS if possible and then take it from there again. Don't fancy at £319 paperweight! I'm usually alright with these things too.
Thanks again (And if anybody else has any other input in the meantime I would be grateful - I'll try anything at this stage!)
I'd say its a good thing that the PC exhibits varying behavior - because that means there is still hope!
It really boils down to if you can open an adb.exe shell to the device. Can you? It would not be when its showing as MTP but it would be when its showing as adb in Device Manager. If you can then here is a thread where I explain (pretty good, I think) how to get back to stock:

Can't really get into much on the Tablet itself. It boots up, gets to the Google logo (with the padlock symbol at the bottom suggest it has been partially rooted (?)). I can get into the Bootloader by holding down the Power + 2 vol buttons. Once in the Bootloader I have the options of Start/Power Off/Recovery Mode/Restart Bootloader.
When I go into Recovery Mode I can get access to the blue menu where I get the options to restart/something about adb/wipe data/factory reset/delete cache partition (paraphrasing here).
Don't know how many times I've tried the wipe data/factory reset option and reboot but always get sent back to the same loop.
I'll give you're other idea a shot as well later. Thanks again.

bigmatty, you the man!
Managed to get back to factory stock following yours and styckx's guidelines. Couple of little teething problems along the way but nothing I couldn't get around.
I now have a fully functioning Tablet again and I thank you for it.
Might give the Rooting a miss for now but if I come back around to the idea I'll be sure to follow the guides on here this time instead.
Thanks a bunch again for taking your time out to reply to my thread and get me back up and running again. :good:

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!
If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

changes to this disk's partition table!

My device is not rooted, is this the problem?
Please help me!!

@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:

Nope it isn't the end try to install the recovery again or try to push the custom twrp recovery again to the right partition! Dont give up that fast when i hear your things then its still fixable! you already got the factory reset processing so try to Push the Recovery again and search for an guide about recovery maybe Then you would probably get your device fixed.
Just read my things about simplicity so think easy and you can fix it. AND STAY POSITIVE You will repair your phone today :good:

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.

Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.
Hello, I am a new member and I'm having a hard time trying to fix my phone.
Currently, I can't go into any mode. I have neither fastboot or download mode.
I also can't get into my twrp through factory reset since it tries to reboot my phone.
However, whenever it tries to reboot, I get error: Boot certification verify and the screen goes dark.
I have tried to solve it by following this thread:
http://forum.xda-developers.com/showthread.php?t=2582142 but nothing has worked so far.
Can anyone please help me?

By that do you mean you can't even get to the factory reset screen at all? Or you do get there but when you select the option to reset, it simply reboots at that time?

I get there and selecting reset reboots the phone. However, an error about phone ceritication verify pops up
If you have access to a Windows machine, plug it in while on that dark screen and open device manager. Does anything show up relating to Android, Qualcomm, etc? If need be, unplug it while watching device manager then replug. Is the device showing up at all and if so, what's it called?
edit: also try long pressing power for 15 seconds to turn off the device completely. Then short press power (2-3 secs) as though restarting the phone from an off state. Does it boot into the OS then or no?

Thanks for the reply! I have tried that and my computer recognizes my phone as LGE Android Phone. It seems like I can't get into any mode at all

Hmm, that's not so good. Most of the people who've been experiencing this have accepted either willingly or unknowingly, the new vzw ota update. But others have still been able to boot into the OS normally. It's booting to system from recovery that's been the only problem for them which makes sense considering aboot and boot were updated with the ota. That will break the loki <>TWRP connection since we need a downgraded aboot (JB) and a patched kernel for proper function. Hence the secure boot error.

I would hold tight for awhile and see if anybody else has a more simple plan because I do not. The only thing I can think of with no boot, no recovery, no download mode AND no bulk mode, is to try and force bulk mode as described here:
http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
...then use Linux to fix as described here:
http://forum.xda-developers.com/showthread.php?t=2582142
(though I would ammend those intructs slightly to include the dd writing of boot and laf also to restore download mode)
...and then use a restored download mode to return to stock using a vs980 tot as described here:
http://forum.xda-developers.com/showthread.php?t=2432476
An unfortunately long and less than simple path back to a booting phone, especially for someone new to root. Again, hopefully somebody else can offer up a better plan.
Be very careful

I was in exact same spot, until I got into the dd / phone partitions part under Linux. AN ERROR THERE COULD BE FATAL.
Please be very careful, look for a thread on recovering from "Secure Boot Error" (havent found one specific for that yet) Alot of people had success using the Linux method, I did not (vs980) probably because of a typo (keyboard error, mine) using the dd command.
I'm not saying don't try it, I AM saying use extreme care make no keyboard errors

It seems like i have messed my phone up really badly.. Thank you for the ideas but yes, I will continue to look for more options for now
Edit: I have never tried the first method you showed me before but I have tried the second and the third method and did not work. Would I be able to fix it if I take it to a shop?

Thanks for your reply but I absolutely have no idea how to get into the dd / phone part using linux. I'll continue to look for more threads close to my problem but I have no clue as of yet.
A few posters here claim that the G2 is unbrickable - but I think I can challenge that. It started off with me wrongly flashing the Cloudy ROM 3.0 - what I didn't realise only till later was that it was intended for the Korean variant of the G2. Dummy move indeed.. I had previously taken the necessary precautions and took a full titanium backup and ROM backup onto a USB drive via TWRP - I previously ran Cloudy ROM 2.2 with Dorimanx Kernel on KK 4.4.2.
Right now, the phone doesn't seem to power on via buttons. When I plug it to the PC via the USB, I get "QHSUSB_BULK" as an unknown device only.. no black screen while on, no drives or COM port.
First off I want to be clear that I know I and only I am responsible for bricking my phone - The reason I'm in this mess is completely down to my stupidity, and trusting 'educated guesses' instead of confirming specs black of white. Just wanted to be clear in case anyone gets the wrong impression.
So this is more or less the sequence of events;
1. After flashing, I got stuck in fastboot mode.. (can't find the link) I followed one post where I needed to flashed .img files via the Fastboot CLI (similar to ADB). I used the images from the LG G2 D802 16GB in europe. source.. It was a toss up between the EUR and non EUR, and so I made the first of my so called 'educated guesses' that sent this phone deeper into the ground.
2. Something went wrong as when I rebooted the phone (had no idea what had gone wrong at the time), I got no logo. After some time, I noticed the screen on with a black background. when plugged into the pc, the QHSUSB_BULK would appear and with it a bunch of drives that Windows thought needed repairing. so I followed This .. I installed ubuntu, booted to terminal so I don't get those auto discovery pop ups, I used the images recommended there for my device (again, it seemed to make sense to use the same that the OP was using for my LG G2 D802 16GB in europe... After I rebooted, it was to my horror that the screen didn't even turn on, with no drives being detected via USB.. just the QHSUSB_BULK. This is what made me realise that the culprit was most probably using wrong images rather than improperly executing the instructions.
3. I opened the phone and tried shorting some capacitors where I'm supposed to see the drives again to no avail. I even tried shorting the capacitors ends as described here to no avail. I done a good full hour shorting the hell out of those capacitors (the post says to keep at it till it works cos it can sometimes be a bit tricky) but I saw no change. I would like to try the DL mode described there but I can't figure out what I have to ground from the images shown in the post regarding the "BOOT CONFIG".
This is basically the state the phone is in at the moment. so to recap:
No bootloader,
no recovery,
no fastboot,
no download mode,
no drives when in QHSUSB_BULK mode,
no COM port.
From the multitude of unbricking guides here, I gather that I either need to see that bunch of drives again when via USB or a COM port. I tried installing Qualcomm drivers, thinking that if the pc recognises the device, I might get the pc to identify the COM port, but the driver couldn't be installed for the QHSUSB_BULK device (got some error.. I can update this post later).
I tagged this post as a question.. i'm sure there's a question here somewhere...
HELP?!

When I first tried to enter QHUSB_BULK mode on mine, I took ages. Seriously, ages. It kept not showing the drives. Important thing to remember, in my opinion, is to use Linux (latest Ubuntu in my case). If you keep trying, eventually they will pop up for a split second. I can't remember how I did it, but you have to use a partition tool, I think, to get it to freeze the positions of the drives. Then, once it's 'mounted' them, you can try (and keep trying) to flash to each partition.
Mine was well and truly screwed, so I flashed a blank partition table on, then flashed each image onto that. It took a lot of trial and error, though, because it kept not showing the drives.

Mine was exactly the same I also had a blank partition table.. Anyway just keep trying because It took me a while to get mine working.. I was trying to short the capacitors but it seems to be quite hard sometimes especially if you aren't carefull.. Because you can start to mess with the soldering of the capacitors and it'll be harder after that.. It happened to me..
Anyway here's something I've wanted to ask everyone, after I sucessfully put my phone back to life, it seems like the middle button isn't working, the LED and the volume rockers are fully working, but if I ever press the power button after some time it shutdowns just like if I pressed and hold for a while, has anyone got this problem? It seems like the flex cable or something is damaged but i wanted to be sure it's really damaged or just something I could solve.. thanks and sorry for the off topic..
