[Q] Need some help here Stuck on bootloop, Can only use TWRP - G2 Q&A, Help & Troubleshooting

Hello everyone!
I'm having a bit of an issue. apparently everything was deleted on my phone for some reason when i was using my phone. I decided that I should just Factory restore through TWRP and reinstall kitkat 4.4.1. when I went to go factory restore I see that on the commands it says "Unable to mount, failed to wipe dalvik, wipe complete Failed" I took off the -rf on the settings check mark and when I go to Factory reset, the phone stays on "Formatting Cache using make_ext4fs function" the progress bar is moving but after several minutes it's the same screen no changes no failed messages or anything. almost like it's still trying to format. - my phone starts to get kinda warm. I have tried sideloading a ROM but my computer doesn't seem to pickup my phone. Instead when I hit to sideload through adb in the device manager i see "Other devices g2" with a question mark.
I do have the LG usb drivers and also I believe I have adb installed.
What else can i do? My phone still tries to boot but all I get is the boot animation over and over again.I tried the "LG G2 Stock Firmware" thread but the program says wrong phone model.
I had installed Kitkat 4.4 with Wootever's version 6 kernel and my phone model is d800.
Thanks for all your help! Seems like flashing was a lot easier on my previous HTC One X+ lol

If ur adb can see ur phone in sideload mode then sideload kitkat Roms and gapps and the kernel.

Deleted SDcard somehow, still have OS though...

Flashed CWMR 6.0.4.4 Touch so I could try to flash Gummy Rom on my friends VZW G2. As soon as I touched "Wipe" and chose to wipe...assuming it would be the same as TWRP option which is safe unless you click additional wiping options. It froze mid wipe which freaked me out. Finally when I gave up and rebooted the device, it wouldn't recognize the SD card but booted into his previous ROM just fine.
My question: Can I somehow use ADB to fix this without reverting to stock? I'm not sure Fastboot is an option unfortunately.
Thanks for any/all input. I'd prefer not having to revert to stock and then re-root as it's late and we both work in the morning.
EDIT: Was able to ADB sideload the ROM and Gapps. Just waiting to see if it reboots and shows the sdcard...is this pointless?
So it got stuck in a bootloop for the Gummy Rom after adb sideloading that and Gapps. Looks like returning to stock is the only option to fix this mess? Is it a common issue to have the Touch version of CWMR freeze when doing any wiping process?
Yes it is common, it takes so long to wipe cache. Only fix would've been to use twrp and select "use rm -f instead of make_extfs4" in settings

[Q] Cannot mount anything in TWRP, sdcard folder empty

Hi All
I am in the process of flashing Cyanogenmod 11 onto my TF300T however I am in a world of hurt. First I updated to the latest TWRP (2.6.3 -4.2). When i boot up into TWRP it is asking me for a password which I do not know. If I press Cancel i cannot see any contents of /sdcard. Also if I insert a microSD card, again cannot see any contents. TWRP is telling me there is no operating system installed and if i reboot it just comes straight back into TWRP.
I apologise if this question has already been asked but I just cant figure this one out.
What bootloader version do you have? What helped me was to reboot into the boot loader (using volume down+power, has three options RCK, cold-boot linux, Wipe data [dont ever ever ever wipe data]) and select cold-boot linux (the android guy in the middle) and it would boot back into my ROM. If you cant get in that way, you are going to have to use ADB on your computer and use the "adb reboot-fastboot" command. If you get in, back up your files, because you're at the event horizon of losing all your data. If your bootloader is 10.6.1.8 youre going to need to flash the latest asus stock firmware from their website.

I am using bootloader 10.6.1.3. When I cold boot linux it just continually boots up into TWRP.
Whenever I try to run an ADB command i get "error: device not found". I have installed the android SDK, tried to install the USB drivers but no luck (possible windows 8 issue?).
It doesnt matter if I lose all data on it, i dont keep anything really important on it.
I have rolled back to 2.5.0 TWRP and it still asks me for a password.
I've switched over to my Mac now and have been able to push the CM-11 ROM into the sdcard directory. However when I attempt to flash it, it fails immediately with the log saying.
E:Unable to mount '/system'
E:Unable to mount '/cache'

I had something similar, tried many things but nothing worked so i ended up flashing stock ROM again with fastboot.
If you need help on how to do that just let me know.

Ok this morning I have tried the following:
1. Flashed Scanno's TWRP from the OMNI thread using this command:
> fastboot -i 0x0B05 flash recovery recovery.img
2. Booted up into TWRP, again /sdcard is empty.
3. Pushed the OMNI ROM onto /sdcard using:
> adb push omni-4.4.2-20131218-tf300t-HOMEMADE.zip /sdcard/
4. Went to Install and selected the zip then it immediately fails saying:
Unable to mount '/system'
Am I missing something here? From above i see that i flash 'recovery'. Do I need to flash 'system' with fastboot?
no, but maybe your PITs are corrupt. do you still have an older nandroid backup you could try to restore first?
oh just read that twrp asks for password. is that still the case?
Sent from my GT-I9505 using XDA Premium 4 mobile app
Yep it's still asking me for a password.
What are PITs?
I'm not sure if I have a backup. When in TWRP if I go to restore it can't find any. It's like the whole tablet is wiped. Does this have something to do with not having the ability to mount anything?

Ok, Buster99 I followed your instructions over at this thread and am now back up and running with stock.
http://forum.xda-developers.com/showpost.php?p=44244313&nocache=1&z=9056634965818376
For me to go to KitKat, can I just flash the OMNI ROM now?
EDIT: Nevermind, I am all back up and running, thanks so much for the help, i was getting a bit worried that I had bricked it!
HELP
So I just tried getting cm11 on my tf300t, i installed TWRP 2.5 and rooted my device, everything went well. I then did a factory reset and wiped cashe. I tried installing then cm11 zip file with no success. I get the message that it failed. And now im on a device with no ROM to boot into and no working ROM to flash on the device.
Since there is a SD card slot on the device, would it be possible to put another ROM on there and then flashing that?
Please help me!

in order to install CM11, you need a special TWRP modded for KK: http://forum.xda-developers.com/showpost.php?p=48508679&postcount=7
You can copy a CM11 nightly and the TWRP onto a SD card and flash from there, or use fastboot.

Hello, i have a similar problem, i wanted to install CM11 on my TF300T, i downloaded the latest version of TWRP from their site for the tablet, installed via Fastboot and everything seems to be ok, when i try to flash it (via CM OTA) it ask me for the password and it didn´t mount any data, but when i reboot the tablet it just keep loading twrp and i can't get to fastboot nor adb nor APX, so i have no idea on how to restore or boot back to the OS, or i just bricked the device?
thanks

When you restart you tablet, and hold the vol down key while rebooting it will give you a bootloader number: 10.6.x.x.x

that's the point, it doesn't do anything, is like i'm not holding or pressing it, it just show the ASUS Logo screen and in the top left it says that the bootloader is unlocked as usual, i don't think is a wardware problem because it was working the last time it booted on Android

Once it goes to recovery, adb will be accessible. Then follow Buster's recovery method.

accidentally wiped everything after getting stuck in boot loop

As per the title, I accepted the system update on my rooted ls980 (didnt know it would mess anything up). Ended up putting me into a boot loop to TWRP recovery. Tried to restore all my backups and none of them yielded a different result. Thought i would try a quick wipe but i accidentally wiped everything... For some reason when i try to install the newest USB drivers it tells me the install worked but never recognized the phone. I have done all the steps in this thread http://forum.xda-developers.com/showthread.php?t=2432476 but not everything installs when plugged in from download mode. Also could not get LGflashtool to register properly. I'm not exactly sure where to go from here, I have no roms, backups, or adb access. what do?
Well if u can boot ur rom into recovery, then connect s pen drive with s flashable rom inside to ur mobile via OTG cable, and then flash

Can you put the phone in download mode ( up volume while plugging to USB)? If you can, restore to stock using LG Flash tool.
forum.xda-developers.com/showthread.php?t=2432476
The stock recovery doesn't support sideload. The only fix is to restore stock with flashtool
You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too

Destroyed my girlfriend's phone

Someone please help me! I was trying to install Philz recovery by flashing it from twrp recovery but Philz recovery didn't show up when I tried going to recovery mode. Instead the screen just went black. So I restarted the phone and tried to use the android terminal to flash it manually by typing..
Su
dd if /sdcard/recoveryfilename.img of=/dev/block/platform/msm sdcc.1/by-name/recovery. (I don't remember the message the terminal gave after that)
Now, judging from the fact that 1)the internal storage is now empty. 2) browser crashes when trying to download files and 3)superuser won't work for any app (apps that I'm trying to use to somehow flash back the twrp recovery so I can restore a backup ex. Flashify)... I'm assuming I made a mistake when typing in android terminal. Is there any hope for me or do I have an expensive paper weight?
Extra info: I can boot into the rom (aokp 4.4) just fine... No more data or cell connection... wifi still works. LG G2 803. Bell Canada.
Please if anyone has any tips help me out. Thank you in advance. I'll continue searching for forums for answers.
Edit: a potential solution i found is to flash a stock rom with the "r&d tool" but will that bring back the files in the internal storage?

freegee from the market will install a recovery.
as a last resort you can flash back to stock.

problem solved. Used the last resort, but immediately after flashing kdz the LG logo kept bootlooping. So I did factory restore by holding down up button and power button. Thank you.
