Hi everyone. So i have an lg g3 d850 version, I had rooted it installed cyanogenmod 12 and twrp recovery, everything was fine. Problem came up when i tried to upgrade twrp recovery to v3.0.0.0 (latest version). I downloaded the twrp.img into my sd card, I used Flashify and erroneously chose FLASH BOOT IMAGE instead of RECOVERY IMAGE. Since they are both .img files flashify flashed it. I tried to reboot my phone it would not boot, just kept displaying on and off the lg logo, i guess it couldn't find the correct boot image. I thing flashify flashed a recovery .img into the boot partion (what a bummer!). So I tried to restore phone to stock, it booted into download mode (vol up+usb cable), used the lg flash tool and installed the stock .tot file with its dll, went well to completion. Tried to boot again, but it would not boot. I guess the boot partion is still unflashed. Someone please assist me on this problem, is there a way i can get and flash the original boot .img into my LG G3 D850?
Flash Boot from CyanogenMod
Hello and thank you for using Q/A,
you can download the CyanogenMod 12 ZIP and extract the boot.img from Cyanogen. Now flash the extracted Boot.img via Fastboot.
Kind regards

Do you have a step by step guide on how to do that? Remember the tot method completed, so i guess its back to stock.

On computer -> open the rom zip via winrar or any archive utility, find boot.img, copy over to phone (connect while in twrp), tap on IMG in twrp (there are 2 options - zip and img, currently it´s zip mode), then find the boot.img, choose to flash and select "boot" or "kernel" (it asks you if it´s recovery or kernel)
Don´t panic , you have twrp at lease
I don't have twrp
Well doesn't make sense.
-you had older twrp
-you wanted new one
-you flashed it to boot partition?
It means you can't boot Android but you still have twrp
volume down and power,wait for lg logo. Release and hold again..confirm twice

Hi guys
I am trying to install the latest TWRP, but every time that I try to boot into recovery through "adb reboot recovery" the phone restarts and I see the android maintenance logo.
What I did up to now:
1) I unlocked the bootloader following LG site instructions successfully. I have the bootloader unlocked message.
2) Downloaded TWRP to my windows PC for H815. After doing "fastboot flash recovery twrp-3.0.2-0-h815.img", the result seems to be successful as I get the expected OK message.
3) I try to reboot to TWRP through "adb reboot recovery" but every time goes to the maintainance logo. I tried also the button combination but I cannot see the Factory Reset menu or the TWRP menu.
Just to mention that I was completely stock V20d without root at the beginning and that the phone boots fine for the moment.
Please help.
No one had my issue? I am still trying to install TWRP and I only manage to boot it temporarily from the PC..

twrp needs to be flashed from within twrp. First boot twrp:
> fastboot boot twrp.img
Now you install the image as recovery.

I think this was the first issue, but after I should also remove the "read only" from TWRP in order to keep it in the recovery.

Not quite right. You can flash twrp image from twrp recovery. No need for a zip.

Hi guys i flashed the 3.5.3 CM today but i decided to go back with 3.26 again, so i followed a guide that tells me to install stock recovery over twrp before i install the rom but after i fastboot flash the recovery i cannot go into the recovery anymore.
i tried to flashed the modified twrp and then boot to recovery but still wont open it.
the phone works and can go into fastboot still but it just wont access recovery
anyway to fix it? sorry if this has been discussed before. im on a mac for more info
TIA

Is your OS booting?
yea
Got the same problem here. Can boot into system and fastboot but if boot to recovery i get the oneplus logo and the bootloaderscreen and then i get a black screen where i should get my recovery. And if wanna Force shutdown my oneplus it freezes somehow. I tried everything to fix this with no result. Stock recovery doesnt work too.
Hi I just had the same problem, I have sent it back to Oneplus for repair. According to the ticket, I had a faulty motherboard, which has been replaced. If you can, do it. I only had to wait for a week before it was sent back.
Had the same problem last night. Following method nr 2 in thos thread solved it.
http://forum.xda-developers.com/showthread.php?t=3405700
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
using fastboot to wipe the recovery partition then fastboot flashing modified twrp twice worked for me, i think the oneplus recovery image thats doing the rounds doesn't want to play nice lol
If youre phone boots in to system, download Flashify from play, flash recovery.img (you need to extract .img file). Go to recovery to check if it works. If not try other recovery.
after flashing the community build i cant boot my device in fastboot mode, it wont start the recovery or boot the system sucessfully.

If your device is unlocked, flash the recovery.img from fastboot.
You can download TWRP for oneplus 3 from their site.
Rename the downloaded recovery to recovery.img.
And open fastboot in the path of the recovery image.
Use the command:
Code:
fastboot flash recovery recovery.img
Hopefully this helps

managed to fix it the other day, by flashing the modded twrp.. somehow that one worked after that i flashed the 3.26 plus the 3.26 modem ones because if i didnt, my touch screen wont work...
For me, I flashed the twrp from fastboot.
But still the 1+ logo shows when I try to boot in to recovery for 5 sec and shuts down with 2 dots of lights in the navigation button area
The normal boot is working fine. Did flash the recovery using apps like TWRP Manager, Flashify etc. It will show successfulll. But when I try to boot in to recovery, same result.
Please help
Hi. Im new to rooting and on the attempt to install lineageos, i got stock in full wipe.
First i unlocked my bootloader and then installed twrp. everything went well so far, but in twrp i made the mistake of doing a full wpe. now i dont know how to boot into custom recovery, if it even still exists on my phone. i also tried the lg flash tool, but i always get the connection to server error. would be really gratefull if someone would help me out. thxs
so... you don't tried enter to recovery via key-combo? (Vol Down+Power).
If you can enter to Download Mode, try to flash a KDZ with LGUP.
I can't flash kdz because lgup not recognized the device because i flashed a old marshmallow system on my lg4 with v30 port ..any help

Try connecting to your phone in Android SDK/Platform Tools.
Type adb reboot recovery and see if it will boot into TWRP. If it works, you have choices to restore a backup or flash a new rom.
If it doesn't boot into TWRP, make sure your TWRP recovery.img is in the same folder and try re-installing by typing fastboot flash recovery TWRP.img (using the file name of your TWRP image).

Just extract and fastboot flash the original boot.img from the factory image. You'll have to open the nested zipfile in the image file to get to it. Once you flash it, you should be back where you started and able to boot system. Retrace your steps and found out what you did wrong. Which kernel? As a side note, you should first fastboot boot the TWRP.img file and then while you are in TWRP, you flash the TWRP zip file. You can also use TWRP (boot) to queue up TWRP, Kernel, and Magisk and they will all flash in that sequence saving some time. There are also sticky guides on how to do this.

Yeah appreciate it i figured it out last night this phone drives me nuts
Hi,
I made the mistake to flash magisk (from TWRP) and now my v700 will not boot anymore and also won't power off.
I wanted to flash stock Kitkat... but can't get to "download" mode... I can get to TWRP, but I don't think that helps...
Did I just brick my loved v700?
Thanks.

Well, I managed to fix it.
As I had TWRP installed, I extracted the boot.img from the kdz and "dd" to the partition but... I also had wipe out "internal storage" in one of my tries... so that didn't fix it, but removed the "error boot credentials"...
So I decided to follow the instructions to convert the kdz to an zip... and flash that zip and it worked!
