Coming from a phone with microSD extension, I had never encountered such an issue:
I bought this phone with a stock 4.2 Rom installed and tried to install a custom Rom. I first installed the latest version of touch recovery (tried it and it seemed to work fine) and did a backup using the default settings. Then I erroneously chose to format system and data, thinking that I could then "install from zip". Strangely, these steps deleted everything in the /sdcard directory and I couldnt select "external SD" (because the phone isnt equipped with it anyways?). Then I made a second mistake and restarted the phone, despite the message warning that I no longer had an OS installed. I took the battery out, and then held the power down while pressing the power button. The phone couldn't get into recovery, but instead showed a screen with the android logo, a large "Start" sign above it, and "Downloading...", "Do not turn off target !!" below it. Pressing the power button now got the phone to show just "Google" and a lock logo under it. The PC (windows 7) can not detect the phone throughout the process.
I tried the latest tool kit and samsung's USB driver but couldnt get the phone recognized by the PC.
Does this mean that the phone is doomed???
Please help!!!

Relax, it's not easy to 'doom' your Nexus. Especially with all the hard-workers in XDA
Try accessing Recovery mode by holding down BOTH vol up + vol down, as well as power. Holding just vol down + power is 'Download Mode', and at the least you can get to this. Means your phones far from doomed
Thanks a lot for the reply!
As a matter of fact, I also figured out how to get back to recovery (if only I had read your post earlier, my pain would've been much less!). But the problem remains that I can not get a target ROM onto the phone, since: 1. whatever I did seemed to have gotten rid of the nand backup supposedly stored in /data/media/TWRP/BACKUPS/ (I'm using TWRP V. 2.3.2.1). 2. I can not get my PC(or Mac, for that matter) to recognize the phone or the internal storage.
Any pointer from here?
Thanks again!!!

You can download a factory image and install with fastboot. It's quite easy and instructions are readily available on this forum. You can then install a custom ROM afterwards if stock is not your thing.
Found the answer finally!
It's the adb push method. Basically, it's to install adb drivers and execute a few commands via the command window. Not too bad... Don't know much about fastboot yet though ... If anyone else needs more details, please PM me (to save public bandwidth).
Thanks a lot anyways, whpnhp and jocalderone!!!

So I just got an LG G pad 10.1 VK700 from Verizon the other day. I rooted the device on the first day but never really added any additional apps or software.
Another member in the household was using the tablet and it asked if they wanted to accept the VZW Update for KitKat 5.0. They downloaded the update, and now the tablet is stuck in a bootloop at the Fastboot screen.
There are only 3 options I can select from this screen in the top left using the volume keys: RESTART, RESTART BOOTLOADER & POWER OFF. Any time I select either of the restart options, the screen just goes blank and hangs. I have to manually power off, and upon turning back on I am right back to this limited Fastboot menu.
Bottom left reads:
FASTBOOT MODE
PRODUCT_NAME - E9LTE_VZW
VARIANT - e9lte_vzw Toshiba 16GB
HW VERSION - rev_10
BOOTLOADER VERSION - N/A
BASEBAND VERSION - N/A
CARRIER INFO - N/A
SERIAL NUMBER - VZ7005xxxxxxx
SECURE BOOT - disabled
LOCK STATE - locked
I booted into Recovery mode, but any of the options I select from the System recovery menu send me right back to the Fastboot screen.
Is there anything to be done at this point?
UPDATE: Problem solved. Research into the other variants of the LG G Pad lead me to the the LG Mobile Support Tool, which you can find by googling B2CAppSetup.exe.
Now, if you are stuck in a Fastboot loop as I was, I ended up having to restart the device while holding down the Power + Volume UP & DOWN. This brought up a screen displaying a bar code and the device MSN and IMEI number. Using this number return to the LG Mobile Support tool and select Options>Upgrade Recovery. Even if your device is already plugged in via USB, the software will not recognize the device -- you may want to double check to make sure your device drivers were installed prior to this step. Input your IMEI number into the box and restart the device in to download mode. It took a few attempts due to the quick action of Fastboot, but I was finally able to access the menu while USB was plugged in to the device and restarting while holding the Volume + key. Now you can continue with the installation and you will be back into your tablet in no time.
I have access to the device via usb / fastboot, adb is not registering. If anyone has any suggestions on what I can try, please let me know. I do not have a backup or a version of the OEM ROM. Every effort so far just sends me right back to the Fastboot screen with 3 options. Anything I can run from command prompt using fastboot alone that would help in this situation? Any way to do a factory restore without having an actual OEM image?
Well im stuck at the verizon screen too but for a different reason

Hello I have the exact same model I got 28th my g4 and successfully rooted with kingroot and used supersume to change it to supersu. Everything was perfect and running fine and I tried an entropy engine I use on my other rooted phone and it was not help so I disabled it and rebooted like I have with my other one before and it stuck at that horrible red screen lol. I haven't done anything else major to alter anything to do with the OS like installing an OTA and I can only get to the same screens as you. My problem is I don't have a PC and haven't in a very long time and if I get to one I wouldn't know where to start out, last computer I owned has a floppy disk lol but I don't see how I would need to re flash the entire OS because of an entropy engine hickup. If you or anyone know of a way to slap this thing back to reality I would highly appreciate it. I got very familiar with the android os and how it works but never had a PC to go beyond a basic root so technically I'm still a noob in a way. I only care to expand dual window to other apps if I get it fixed cuz I'm not gonna risk screwing with it any more now than I have to, my luck is too bad lol thanks in advance

If you are stuck in this particular Fastboot loop without a computer I am afraid your options are going to be very limited. The only thing I can imagine that you would be able to try is restarting the tablet while holding down the Power + Volume Down keys to access the stock System recovery menu. You can try to use Factory data reset and Wipe cache to see if that can resolve the issue, but for me every attempt to perform actions from this menu brought me right back to the Fastboot screen. The only other way I could communicate to the device in this scenario was using command line, and even then I could only access fastboot and not abd.
I would highly advise getting at least a cheap older laptop with Windows if you plan on rooting any device, otherwise the dangers will far outweigh the benefits. I'm just hoping some development comes along for the VK700 G Pad 10.1, at least a TWRP or CWM release.

Thanks for your response, I have unfortunately tried that too and wipe cache, reset , all back to fastboot. I figured it would be impossible without a pc. Oh yea my stock recovery says modified in the top left corner, but anyway I can get access to a PC But honestly it's been awhile since I even needed to use one and don't know exactly where to start, like navigating around, and how to install what software on the pc. I can't find anyone that will walk me through it locally or online and every tutorial I find is missing some lil step I need. I know Android in detail but after basic root my experience hits a brick wall. I'm capable of more jus got to get broke in on a pc again. Now I only care to root for stuff like freezing apps, gesture control, and really want to use any app in dual window. Ain't screwing with any system tweaks again it was pointless lol I guess I need all the right files and hit up the pc...can't really do worse no??

Oh yea I almost forgot I got side tracked earlier. I know there is already a twrp, I have 2 versions (2.8...something and the next version strait off twrp site. I was the one guy it wouldn't flash through flashify for but others claimed it did. God knows really, but I'm gonna wait till I have a PC of my own before I touch my g4 but man the ability to open any app in dual window is just too damn sweet...if I could only change that one word on build prop to false without all the other hassle

I tried following your recommendation, but the LGMobile Support Tool said the device wasn't plugged in no matter which combination of buttons I pushed while running the Upgrade Recovery option, and I wasn't able to figure out how to get to download mode either.

If your problem is from an OTA failing due to taking it while modded and you can get to fastboot the following command might fix it:
Code:
fastboot erase cache
That will delete the OTA zip and break the bootloop.
I have just flash the custom 5.0.2 ROM using philz touch 6.48.4.
After I flashed the ROM, I reboot to the philz recovery and flashed back to cwm 6.0.4.8.
However, the device stuck on the LG logo screen.
I have try to enter Download mode/Emergence mode/Hard reset mode/Recovery, but all of them I cannot go into.
Please help! Thank you for your helping!!

Your boot loader is broken. Gonna have to get to the down load mode and reinstall either the or the stock. You can probably flash the recovery with .IMG file with lg flashing tool. Nerdy blond's twrp is one of those files that you can use. You can even try installing it first with the adb shell command, you can get the instructions at the same place where you download.

Thank you for replying.
I cannot do anythings since I cannot enter into download mode.
I pressed volume key + and - and insert the usb cable to computer. There is nothing happened, computer dose not show the devices attached and the phone stay in the LG logo screen.
Also, I cannot use adb commands to force the phone enters into download mode as it shows nothings under "List of devices".
Is there any methods I can go into the download mode???
Thank you!

If your phone shows LG start screen, it should go into Download mode. I had similar problem few days ago while I was testing some kernel patches, it just froze on the LG screen. Solution was to unplug it, remove it's battery, SIM & SD (you don't have to remove SIM & SD, I just work that way) , make sure it's off, return battery back, press Vol + & Vol - at the same time and plug-in the USB cable.
Before that, make sure you have installed LG Unified driver (can be obtained via LG's software from support site), because without that Windows won't recognise your device.
After that, once you make your phone usable with Freegee/whatever you use to install initial recovery, flash official TWRP, because others are too old - that Philz CWM is old but still working with Lollipop but not work good and is tends to lock itself into a bootloop if you use hardware keys to enter; that other one, from GPRO_recovery APK is not supported and not working well (for me since day one), so it should be replaced as soon as possible.
Also, I can suggest you to flash your phone from stock 4.1 (not KitKat), root, flash recovery via freegee and after reboot update to latest official TWRP via Flashify.

I have tried to reinstall the LG driver and try to enter download mode again.
The screen is still stuck on LG logo and I cannot find the device in hardware manager (cannot recognize it).
I cannot do anythings until it can recognize it.
(Is it the bootloader is broken? and can I fix it?)
Thank you very much and waiting for your reply soon.:good:

Which version of Windows are you using? It should be displayed under Serial ports in Device manager (named something like LGE Serial device) and LGFlashTool should recognise it immediately. I can't make you a screenshot/check for real name because I'm running Linux right now and can't reboot.
Also, try with another cable/port, remove all other android drivers you may have (Samsung's, Google's...) and disable antivirus.

OK, it doesn't enter download mode. So, step by step:
- remove battery and leave it for 15-30 seconds, return battery
- press Vol+ and Vol- at the same time and keep them pressed,
- plug USB cable in while keys are pressed
It should immediately put you into download mode, with no LG screen, just black screen with gray box and red text I've described to you.

I'm running out of ideas. I have exact same variant (E988) but only time it didn't want to enter download mode this way was when cable I was using was broken...

Hey Guys, thanks for stopping by!
TO cut a long story short- I'm stuck at cyanogenmod loading screen upon booting, after I stupidly tried tinkering and replacing camera.config files on a sucessfully installed CM13. I can not enter TWRP- it brings me to factory reset screen for some reason, I was only able to enter it through the TWRP manager app. I am able to enter download mode however, is there any way to unbrock the device? Would the KDZ method work or would it not?
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
In download mode this is what the device manager states. The computer doesn't recognise it as either adb or fastboot. Is there anything I can do?
Thanks a lot
This menu from LG you access with power + vol. down - "Factory reset" - will bring you to TWRP. Just confirm twice with "Yes" and TWRP will load.

Thank You so much! I didn't want to try anything by myself - that is how I completely bricked a device in the past. It works- than you SO much!
Hello.
I own a Note II which lately seemed to have some problems.
In the last few months, it used to restart somewhat spontaneously (it seemed that it rebooted when its processor or RAM were too busy, but this wasn't a rule). During one night it probably rebooted and next morning I found it stuck on the first boot screen (the one with "Samsung Galaxy Note II").
When stuck on the boot screen, if I press the power button for a few seconds, it turns off. If closed, it gets to the boot screen and gets stuck there when I press the power button. When plugged to power, it gets stuck at the screen with the empty battery that has a loading icon in the middle.
I manage however to get it into recovery mode, however, in this situation, it can't be seen by the PC, unless I put it in adb sideload mode. When stuck on the logo screen, it is seen as mtp device.
In the recovery mode screen, there are many errors (can't/failed to mount /efs, /system, /cache, /cache/recovery/last_recovery, /data, /data/log/recoverylog.txt, /cache, /cache/recovery/log, last_log, last_install.
In Windows, the PC doesn't recognize the model, however, in a virtual machine that runs Linux, it is correctly seen as Note II when in adb sideload mode, but Linux is not able to mount its storage.
I have also deleted cache, tried Samsung Kies and Note II Toolkit.
What I would like to do is recover the data on it. Do you think it is possible, and if yes, how?
Thank you.
Sounds like a failed memory chip to me.
any answer now?

No, I don't have access. What I want is to recover the files on it, if possible.
This may be a problem with the power button. if you can go into download by pressing only the menu button + volume down is because the power button is always pressed.

Sorry i think your partitions broked. I think you cant recover your data. There is has only one solution. Odin and Format....
My device too has pc cant detect my phone. I tried different cable without samsung usb drivers. Pc succesfully detected the my device.
By the way i installed lg usb driver because of someone's phone is lg and they need format.
I think there's no way to recover your data now.
BTW what recovery are you using?
