Use the ADB sideload feature in TWRP to flash a ROM from the command prompt on your PC.

Do you have a custom recovery installed? If so, load a .zip rom and push it via custom recovery...
.... If not, use ADB to push a reflash of a clean install of 4.3

if you are able to boot to recovery. you have to be in fast boot...
you can either use fastboot to flash over
or
boot into recovery and apply a rom via ADB sideload

[Q] hours for searching for nothing help plz!

I ****ed up my phone today I did full wipe (formatted internal storage too, so i can't flash any rom in recovery because there is nothing) and now i've been searching hours someone who can help me? In TWRP i can't mount anything to my pc (i do not know why?) AND adb says me "devices not found" or something like that so can't push any zip-file to my phone via adb sideload. Is there any way to reapir my phone? can someone help me? Thanks alot!
There was a bug in a bunch of recent twrp releases that causes adb to not work in recovery. Patched versions have been made, try finding one for your device.
Added:
If you can't find a patched version, flash cwm or philz recovery with fastboot, adb is working on both of those. You just need a rrcovery image and do
"fastboot flash recovery <recovery-file>.img"
In fastboot mode.
let's try it out!

See the edit to my first response. Fastboot is done in fastboot mode, not recovery, so you should be good. You just need the basic .img file of cwm or philz recovery.
If you are on win 7 try this:
http://adbdriver.com/downloads/
(Adb driver installer)
Run it when you turn adb sideload on in G2 and connect it to PC.
If it fails you still can go buy somewhere USB OTG cable (few bucks) and flash ROM from usb stick like me.
It appears that accessing fastboot pn the lg g2 is not so simple. Sorta like samsung phone deal, where a manufacturer download is used instead. From what I gather, recovery might need to be wiped to access fastboot, which you could do from terminal in twrp, but thats risky. Apparently, a lot of people have gotten stuck in fastboot mode. Best bet would be to reflash stock firmware through lg download mode. Also see this thread for a method to return to stock firmware:
http://forum.xda-developers.com/showthread.php?t=2432476
Once you are back to stock, just reroot and flash revovery, etc.
downloadmode should still work. go back to any kdz for your version
also source and versions post next time

[Q] Hardbricked LG g2

Hi guys.
I did something really stupid with my brand new lg g2. Wanted a custom rom, so flashed twrp recovery.
Then i wanted to flash the downloaded custom rom, but i somehow deleted everything on the phone.
Then i connected my device to the pc, and tried to sideload the rom. That didn't go well, so now i can't enter recovery or anything.
The phone only shows the LG logo or bootlooping.
Is there any hope?
(I tried to send in my phone during warranty, but they said i needed a new mainboard - which is very costly)
You don't sideload a ROM, you instead push it to internal storage via ADB so it can be installed via recovery (TWRP, PhilZ CWM, etc.). So this would be the command from a command prompt, run from the AndroidSDK\Tools directory or from the directory containing the ADB executable...
adb push ROM.zip /sdcard/ROM.zip
... replacing ROM with the EXACT name of the ROM file. If besides not being able to access recovery using this method...
alone-together said:
Hold the power button until the phone turns completely off, then turn on the phone while holding the power and volume down buttons. When the LG logo pops up, let go and re-press those buttons. When prompted for a factory reset, press the power button

... you can't access download mode to restore using either the *.tot or *.kdz method, then this may be your only alternative:

Thank you very much. I was able to reach twrp again, pretty easy. I pushed a custom rom to my device, but even though the rom is installed OK, i wasn't supposed to make my device boot into the rom. The device only boots to twrp. I Installed several roms to see, if this was because of a bad flash, but that wasnt the answer. I wiped everything, and reached the aroma installer for cloudyfas rom. Installed without problems, but when rebooting, it still only boots up TWRP. Can't do anything to reach the rom (s). Any suggestions?
You may need to flash the KitKat baseband. The link is in the OP of the CloudyG3 thread.

Thanks for answer. I did flash the baseband first.
And Tried several roms. Now Im back to stock and Wonder If i really should try again. On my first lgg2, screen Damage appeared When i was flashing a custom rom. I just don't understand Why i Couldnt load the rom after i flashed in twrp.

[OP5, encrypted] Open Beta 3 broke my display!

Tried to flash OB3 and SuperSu on my encrypted OP5 with TWRP. Was stuck at OP logo.
Tried to go back to stable Oreo build for OP5. Again, was stuck at OP logo.
Now the screen is unresponsive in TWRP (can't even swipe to allow modifications on the first screen!).
If I install stock recovery, I can navigate recovery with buttons. I tried installing OOS 5 with stock recovery from internal storage. It doesn't work. I tried to adb sideload. The computer throws a bad_alloc error.
Anyone in the same boat, or good enough to advice?

but u'll lost your data
i had this too, you need to flash stock recovery from cmd in yor pc by:
"fastboot flash recovery recovery_name.img"
then wipe everything,
reboot again into recovery
click on adb
and then download the stable firmware oreo 5
in adb mode with stock recovery put firmware in the same folder
and input - adb sideload name_of_firmware.zip
That fixed my phone, i'll hope and yours will be fixed

Thanks,
The device is recognized well by the computer (when I write 'adb devices'). But when I try to sideload ('adb sideload OOS5.zip'), it gives me an error with bad_alloc. any ideas?

Files all courupted
With stock recovery you can't use adb sideload in windows 10.
If you're unlocked i would flash Codeworkx TWRP, download the OOS 5.0.1 Full Rom Zip, boot into TWRP, copy the zip to your phone or sideload the zip.
If you're not unlocked (and thus being unable to flash twrp) use windows 7 and sideload the zip.
You can download ADB drivers here
Can you boot? Turn on USB debugging , make sure that you allow the device when booted.
Do an advanced devices when in the OS make sure it's there.
Then you can install a TWRP recovery and do what you need to.

be sure your bootloader is unlocked
turn your phone into fastboot
open command prompt to the folder your twrp is in.
rename the twrp image file to recovery.img
do the following command: fastboot flash recovery recovery.img
after that boot into recovery
press adb sideload
on the computer, open command prompt to the folder where your zip file is in.
rename the rom zip file to rom.zip
do the following command: adb sideload rom.zip
done!
Thanks bro, I shall update you on the situation once I done, at work now.
Do I need to “open command promt “ at my sdk folder/plat-form tools?

Cannot adb to the phone in FASTBOOT. adb devices shows nothing when in FASTBOOT, but shows the device when in normal boot.
Hence I cannot upgrade TWRP from 3.2.1-1 to 3.2.3-0. Was trying this so to upgrade from beta23 to the beta 26, now 27 with which 3.2.1-1 seems to have problems.
A 2nd approach, just re-installing beta23 without Magisk18 gives the stock recovery which manages the beta27 install. But then I'm blocked from a Magisk18 install and still cannot use FASTBOOT mode to put TWRP back on.
Thought the adb drives could be old and sought new drivers, even assuming your link is to the most current I don't know how to get my Windows7 to use the zip file. Can you assist? This would let me put the latest TWRP, hence install Magisk18 and be rooted again!
