Hello all
This is the story of my lg g2 D802:
- wipe data / factory reset from twrp;
- format /cache and /data partition with f2fs;
- install Cloudy G2 3.0 with their patch.
When i boot up, i got the screen "Insert PIN / Password for decrypt" or something like that.
Now, i have installed the latest LG Mobile driver from the site, but when i go to download mode, my windows wont recognize my lg g2.
When i'm at the screen that ask me password, windows recognize it! So, if i try to back to stock with lg flash tool 2014, the procedure is aborted because when the phone goes to download mode, it can install the original firmware.
What can i do?
Solved:
I just try to enter in recovery mode.
So, when guys tell you that you should press power button + vol up to enter in recovery mode, they are right!
They wrong about the timing!
I hold the vol- and the power button but about every 2-3 second, i quickly release the power button and then press it again.
It appears me a screen with korean char and then TWRP screen
After that, i format /data and /cache with EXT4 (so, i never have more f2fs partitions in my phone)
Byez (and sorry for my bad english).

You can try DP TOOLS or SRK Tool : the last one can help you to exit Download Mode. If you was under Lollipop, maybe combination key to enter in recovery has changed: try volume down + power (when device is fully poweroff), and then when you see LG Logo, press Volume Up and Volume Down
0. LG G2 4.4.2 D802 CIS
1. Get "root" by Stump 1.2.0
2. Using AutoRec
3. Reboot in recovery mode with TWRP 2.7.0.0
4. Made “backup”, and copied it to PC
5. Made Wipe, Advanced Wipe
6. Flashing CloudyG2 3.3 from external USB OTG
7. After that got black Screen after LG logo
.....
8. Download D802_PATCH_GO_LP_V1.1_droidth.zip, and installed it from Recovery Mode by TWRP
9. Reboot system, now:
Phone cyclically restarts from the beginning and to LG logo, and so on….And I cant enter to the recovery mode. Cool. That can I do, instead throw in the trash?))
I assume you're following directions from this post: http://forum.xda-developers.com/showpost.php?p=61710456&postcount=1304
If so, I see a couple issues. You did not update TWRP to 2.8.7.1 as indicated, and why are you flashing from USB OTG always copy to your internal memory. You likely can get back to recovery, but it takes timing and patience. I've been in the same situation before. Just an FYI we call a cyclic restart a bootloop.
While it's doing the startup hold the power button until it powers off, it will restart again after. So here's the trick as soon as the screen shuts off you have to let go of the power button and immediately do the vol down power button combo, hold them both until recovery starts. If held too long it will reboot again. Like I said timing is everything, but you should be able to get it with patience. Good luck!
You did not use latest TWRP and you did not flash LP bootstack. Go to recovery, delete system, data, cache, flash latest TWRP, then flash LP bootstack, then Cloudy again
To enter recovery, press power+volume down, hold until you see LG logo, then FAST press power+vol down again, white screen will show up asking to factory reset. press power button, then press power button again. phone will enter recovery.

Is it correct?
1. Hold Power on Lg logo
2. When the screen shuts off:release power button and quickly push Volume+Power on the some period?
One time i seen screen with proposal of erase system, i pushed Yes...and now it rebooting again. And some time it was button hardware assignments screen.

You can flash latest TWRP and LP bootstack in TWRP. They are both ZIP files so it will work. I would give you links but i'm not sure which G2 variant you have

thanks, but first of all - i can not enter to recovery mode, ordinary button combination do not work. As i wrote before.
If you really can't enter recovery you'll have to "KDZ".
Look over there: http://forum.xda-developers.com/showthread.php?t=2797190
Find the appropriate rom.kdz, flash it with the tool.
If this worked, root stock LP, Autorec v2 it, enter recovery with key combination or if this fails with tools like "Quick Reboot" from play store.
DO NOT FORGET to wipe system, data, caches and to flash an appropriate stack, then flash rom, gapps and supersu. You can do this in one step.
If you want to shut down your phone, just press POWER for around 10s. Do not flash with battery under 50%.
You may find SRKTool useful.
Try entering download mode and flashing stock rom through KDZ or TOT method. There is a thread called "G2 go back to stock" in G2 General you will find all instructions there
tip: disconnect usb devices like usb wifi dongle, web camera and external hdd, they used to cause me problems when flashing KDZ
hello, Yesterday I was trying to upgrade my G2 d802 to cyanogenmod 12. I wasn't able to do a backup cause I didn't have a space, so I skipped on this stage. I succeed to upgrade to cm12 but my calls didn't work (after I set it) so I did upgrade straight to cm12.1 in the upgrade center in the setting. after that my phone was stuck on cm12.1 logo so I put the phone into TWRP mode and I install cm12 again.
Now my phone is stuck on cm12 logo and I can't go to TWRP or DOWNLOAD MODE but my computer detecting my g2.
What I can do plz help me
Fastboot or KDZ...?
You could try using the LG mobile support tool to perform a recovery.
Turn off the phone, press the volume down & Power together till you get LG logo, then leave the two buttons and then press them again till you get a reset prompt or recovery. If you get a reset prompt then use the volume keys to select "yes" then power button to confirm, you may have to do this twice. The phone will then enter into TWRP.
im using cm13 on g2. works very well.
But when install #supersu via twrp. its get stuck on the cm logo. can't even enter in recovery mode. Pls I badly Need help.
How can I access Recovery Mode on LG V20? I want to wipe system cache partition due to problems with Wi-Fi and Tethering. The only option I have is factory reset. (Volume Down+Power)
Plug in USB cord to laptop.
Turn off phone.
Hold volume down button.
Plug in USB cord to phone.
After you see a flash of blue download mode, release volume button and phone will boot to recovery.
Do your thing.
Side note, Install the correct V20 variant twrp img to recovery so u don't have to do this enter recovery method anymore, you can enter recovery from the twrp app menu.
I tried the method and led me to fastboot, no option to wipe system cache partition from here. I'm missing something? It's another way to solve connectivity problems?
Thanks!

Do you have twrp recovery flashed?
Turn off phone
press volume down and power together until the lg logo displays
release and press the power button
click on yes to reset
and it should land you in recovery if you have twrp installed
otherwise use lgup to flash the kdz to our phone and restart everything.
LS997 (September 2016 security patch), got to the end of root and couldn't reboot into TWRP recovery. The device is recognized in ADB while in fastboot but when I'm at the secure startup it's unrecognized, like USB debugging is disabled.

If you've hit secure startup the phone has likely booted into regular Android far enough to replace twrp with stock recovery. Reboot into fastboot and reflash twrp (you can use the newest twrp if you want). Once done flashing unplug from PC and pull the battery. Reinsert the battery then boot into twrp via the factory reset/volume button method: hold volume down, press power until the screen turns on then (still holding vol - ) tap power repeatedly until a prompt to factory reset appears. Approving it twice boots twrp if it's installed, otherwise stock recovery will do the reset.
Once in twrp go to wipe, then format data (type yes to confirm), then go to reboot, then recovery. Once twrp restarts flash your choice of magisk/supersu.
Once one of those two is installed it makes it so twrp won't be replaced.

Did this, got to the set-up screen (languages, accessibility) and an error ¨com.android.phone has stopped¨ spammed the screen. I tap ¨stop app¨ and the pop-up comes back immediately.
I tried to fix it by factory resetting (in the settings, NOT using the volume down/power button menu OR TWRP) and now I´m stuck in TWRP. Every time I try to reboot to System, it boots to TWRP now.

Power down, then boot to twrp using the volume buttons. Use the wipe menu there to do the reset.

Wiped it, still get the com.android.phone errors.
Unfortunate, makes doing anything impossible with so many error popups.

Reflash your variant's official KDZ using [PARTITION DL] with patched LGUP leaving [aboot], [abootbak], [recovery], [recoverybak] partitions unchecked.
- Once the flash finishes & phone reboots, do a battery pull so phone doesn't fully boot (wiping recovery & encrypting data)
- Insert battery again
- While pressing volume down button - reinsert usb cable so it boots into fastboot mode.
- Follow dirtysanta guide for your variant from running step3.bat onwoards (which flashes TWRP back into your otherwise stock phone).
LS997, no official KDZ. Use VS995, but dump everything with LGUP (bar userdata) before hand
