So I soft bricked my LG G Pad II 8.0 Tablet... Not the worst thing in the world, except that 1.) There seems to be not much at all on the internet as far as stock ROMs or how to guides on fixing my particular tablet. 2.) My computer does not seem to be recognizing my tablet when trying to use ADB, despite having installed all the drivers etc.
My device is stuck in a BootLoop, it will allow me to try a Hard Reset, which is unsuccessful. But it will not go into recovery mode OR Download mode no matter what sequence of the buttons I push and i've scoured the internet trying different button sequences.
My Tablet will charge when plugged into USB, my comp will also go *ding* when i press the power button with the tablet plugged in as if it is reconginzing it and everything. Also Device Manager seems to have it listed with no Exclamation Point or any sign of trouble... Just when I go to use ADB and i search for the device it says *error no device found*
The Tablet just sits there with the LG Logo screen pissing me off more and more as my attempts fail.
I will say USB debugging was not enabled beforehand *cough cough* my mistake
Will reflashing it work by using the MicroSD card method? If that is the only way i will have to just buy one i guess. It did not come with it and it is a Wifi only tablet, no carrier attached.
And if I try the MicroSD method, will it still work without being able to put the tablet into recovery mode?
I believe I have the correct .IMG file for my stock ROM... I just can't seem to get anywhere with flashing it to the device at this point.......
Please Help!

*UPDATE* So I happened to stumble upon a random piece of information that proved REALLY useful in this situation. Someone put in a forum that Lollipop ONLY is detected when plugged into USB 2.0 ports NOT USB 3.0 ports like I was using. So I did this and was able to make my tablet enter into Download Mode FINALLY.... Anyone have any good methods on how to Flash Stock ROM using ADB and a connected soft bricked tablet?
I have already tried a couple methods that I have found and they were unsuccessful. One was using ODIN software and the other was using LG Flash Tool, unfortunately neither worked....

I have a soft bricked GNex that goes into a bootloop of the "Google" splash logo. I can volume up + down + power and get it into the screen that gives options for recovery mode. However, when I click recovery mode, it takes me to a screen with a dead android with the red triangle sign on it. When I connect the phone to my PC, it is not even registering that a device was plugged in.
Are there any other methods or options I have to attempt to get the phone up and running?
1) thats stock recovery
2) if you want your pc to recognize it, just boot into fastboot and install the universal naked drivers.

It's not that my PC doesn't recognize it because I don't have the drivers, I have another GNex and it plugs in just fine. My PC acts as if there was no device plugged in, there is no notification, no unknown device detected, nada. The owner claims there was water damage to the phone so maybe it's hardware bricked?
update: tried a different USB cable and got my PC to recognize the device. Using the toolkit to try and flash stock rom on there. Will keep updated if all goes well
toolkit goes through the whole stock rom flash process but phone is still doing bootloops. any other ideas?
Do it the right way. Follow the sticky on setting up adb and fast boot and put some hair on tour chest. Toolkits are terrible.

Ok, been following the instructions via this topic: http://forum.xda-developers.com/showthread.php?t=1529058
Have gotten all the way to the part where it's telling me to restart in recovery mode and that's when the dead android with the red warning triangle shows up. I also want to make note that I received the phone in this condition so I'm pretty sure the USB debugging mode has not been enabled.
Hello, first I'd like to thank you for your time reading this.
Note: I've searched the forums a lot, even for other LG Devices (G2 for ex) but I couldn't find a solution.
Trying to flash CM12 by _infected (amazing rom, working as a daily driver on my other lg pad btw) and messed up something on TWRP.
-First trying to do a Factory Reset via TWRP gave me "failed to mount /data" and "/system" I rebooted and the device went straight to TWRP Recovery, I rebooted again, this time making sure I selected "Reboot to System" and it went again to TWRP Recovery...
- I did another wipe, this time wiped everything (all checkboxes in TWRP), reboot and... no boot...
Now my LG Pad is at the following State:
- Black Screen (No LG Logo)
- Connecting USB to Windows gives the "connected sound"
- Adb doesnt find device (driver was installed and working).
- Device Manager "refreshes" on USB plug but doesnt show the device (or I can't find it?).
- Holding Power on the tablet while USB plugged to Windows gives the "disconnected sound" -> "connected sound" -> "connected sound".
- Can't boot into Download Mode.
- Can't turn off the Tablet... only Reboots holding Power key.
Please? Any help?
What can I do?
Is warranty void at this point?
Thank you very much for any help you can provide.
I have a G pad in the same situation, and I wasn't able to fix it. I managed to pick up another cheap one, but I'll follow this thread in case you get an answer.
You have to find a way to get it into download mode or you wont be able to fix it with LG Tool
What did you mess up, and how did you install twrp ? Also what twrp version abd base.

For me personally, I assumed it'd be as easy as the twrp page makes it out to be , or my nexus 4 was, so I just went for it. I ran into that secure boot error with twrp, and rebooted back into stock. There was an OTA update, so I did it (stupid I now realise) and that bricked it on reboot. It won't turn on at all. If i plug into USB on a computer it OCCASIONALLY brings something up on the screen, the LG logo I think or something, but I cannot for the life of me get it into download mode. It's at home right now, so ic anot remmeber the exact thing it shows on screen, but almost certainly not download mode, and none of the hardware buttons seem to be responsive for doing factory resets or download or anything.
I managed to send the LG G Pad to warranty and got a new one... Lucky me...
Guess that if we can't get into DL mode they can't either.
However after much investigation I've realized that the problem was a corrupted system partition...
The phone when trying to boot is stuck on the samsung logo. it doesnt progress past this. pressing and holding the power button makes screen go black and then it just returns to the samsung logo again when power button released.
Originally factory
reset phone... no difference,
wiped cache... no difference.
Got it to register in Odin. Odin crashed and hung part way through.
Now... computer doesn't recognise phone (drivers all installed)
Phone still stuck on samsung logo
Can't put in a file on SD card as it doesn't have option to install from zip from SD (think it was standard ROM and not rooted so doesn't have this ability from what I understand.)
Can get into recovery menus and download mode, however as PC can't recognize the phone can't do anything with it.
Anyone have any idea how I can make the computer recognize the phone so I can attempt to reflash it?
Many thanks
I have just gotten a new cable. The phone has been accepted by my computer with this new cable and I've now used the files on this forum to help flash the phone. This site is fantastic. I know noone has mentioned a response to this yet, however the ROM files accessible make it so easy from here. Thanks so much.
Hello Everyone!
I recently tried to root my wileyfox swift but failed miserably. I did the following when fastbooting the recovery image -> fastboot flash system ****.img.
However, i realized my mistake too late, and now my phone is all messed up!
The phone doesnt show anything when i try to start it and i cant access fastboot again, to undo my mistake. My device manager recognizes my phone when its plugged in to my computer but i cant access any files.
Am i screwed or is there any solution to this?
Thanks in advance!!
Try to access the bootloader with the hardware button combo first (volume down + power / volume up + power). If you get into recovery, you will be able to get to the bootloader with adb or a menu entry. Depends on what recovery you have installed for the latter.
In case you have no access to the bootloader (proper soft brick), go for the QFIL method. Avoid using it unless there is no other option.
Here is the thread:

Cant access bootloader.
However, tried your second option and it went well until i got "SaharaDownload fail" at the last step, and now my computer doesnt recognize the phone in device manager. It does not show anywhere that my phone is connected.

Does the phone give any indication of being connected? Notification light, starting the display, etc?
If yes, make sure the phone is in the correct mode and check the drivers - some of the other forum members mentioned this and the gymnastics around the battery. This would be on my to-do list. The device might come up on the device manager as different one, so monitor the manager for any changes once you connect the device.
If you happen to have Windows 7 device laying at you house, you can try with it (if only not to worry about compatibility and sporadic Win10 behaviour).
It will be a good idea to check the turkish website for General Mobile 4G (one of the Android one derivatives of the hardware) where some people have faced similar problems using the same tool.

*It says no port available since i removed the phone*
So i was using my phone and decided to restart it after updating my adaway files but my phone never turned back on. The two press the power button screens did not show up either. I tried to uses the MSMdownload tool since i thought my phone was somehow bricked but that didnt work either, it just kept restarting the download process after everything was completed. my computer makes a sound when its connected and it connects correctly as a quallcomm 9008 device but even after all this nothing is working. has anyone experienced something like this or does anyone have any advice?
did you try to long press both power button and vol up ...you should feel a vibration...
maybe it's not turned of maybe it's error causing the screen to be off... also is there any heat?
Which method of the unbrick tool did you use? First or second? If the first, then maybe you should give the second also a try.

I've tried everything and I used th me second method yet nothing happened. I can see my phone get recognized by the computer and get listed on the MSN device list yet nothing happens after it finishes the process. After the green line shows up telling me that it's completed everything the process restarts writhing a few minutes unless I unplug it. No vibration no nothing the phone just died on me after I restarted it .
Try doing MSM on a different PC with all drivers installed , hope it helps
Try to repeat flashing again, there is no other way. Use method 2only. Extract tool again and try flash.
When I was used Xperia Z1, I bricked my phone with a soft brick. So I installed driver in my PC and flash Kernel though FASTBOOT(ADB) either it's not show Device in my PC (I show just "Unknown Device").
After that my phone can connect to my PC again (Now It shown C9303 or something that meant it know it's a phone).
So I can flash by Flashtools again. Soft brick is not scary as Hard brick, you'll find some way to bring it back easily.
Hope this help!
PS. Bricked Phone is WEAK in Battery, always connect it with charger.
