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.

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.

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
I flashed a wrong file in twrp and my phone went into a bootloop. I want to boot into recovery to reflash the ROM but I can't do it, the phone is stuck into a continuous bootloop (stuck at the Samsung logo and vibrating over and over again). I can boot into download mode using vol down + power + home, but vol up for recovery isn't working.

1. Boot in DOWNLOAD MODE and flash the correct TWRP via ODIN again. Done.
2. If the step 1 doesn't work. Boot in DOWNLOAD MODE, reflash STOCK rom and reflash the TWRP, the one good for your device. Done.

Secret mode wasn't working in the Samsung browser so I flashed a zip that I found on xda that supposedly fixes this issue and cleared the cache and dalvik cache. I don't see how this could have erased twrp from my device. I currently don't have acces to a computer so I can't use Odin, is there really no way to force shutdown it or something?

Enter download mode, once you are in download mode press at the same time power + home + volume down button. As soon as the screen goes black release the volume down button and press the volume up button immediately, then it will boot up to TWRP

Hi, everyone.
I have a galaxy s8 SM-G950FD. I have once flashed TWRP and rooted the device successfully.
Then I tried to install a custom ROM but I got bootloop.
After that, I flash official ROM to unbrick my device. But since then, whenever I tried to flash TWRP again I got this message "Verification failed unable to restart your device the integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data."
My device is still working fine but I want to try to flash a new ROM (even if I may brick my device forever). I don't know what to do. Can you guys give me some advice ?
Thank you!
It's quite a simple fix I think: You need to make a backup of the Data partition and then do a wipe using TWRP. This happens because TWRP cannot handle Samsung's Encryption; the only way to bypass this problem is by formatting once again.

But I cannot boot into TWRP. How can I do that ?
If you're stuck in the bootloop you should press the force reboot key combination: Power Down + Home + Power. After the device restarts switch the Volume Down key for the Volume Up key right after the screen goes blank. That should get you into TWRP (if it's correctly installed), otherwise directly into the stock recovery.

I cant flash/get into TWRP. I tried to boot into stock recovery and do a system wipe/factory reset. Then I flash TWRP again but nothing seem to happen. I tried to boot into recovery and it get me to the stock recovery not TWRP.I did unlock OEM, used Odinv3.12, twrp-3.1.1-2-dreamlte.img.tar.
I had the same issue.
After Odin has flashed the Recovery it performs an auto reboot (if checked in Odin). So at this reboot hold Vol up + Home + Power as soon the screen goes of. You need to be quick. Then it should boot into TWRP.
True, Samsung's stock recovery is very persistent lately and if you tick the auto-reboot you have to be very fast in switching to Recovery mode combo.
Otherwise you can choose not to tick auto-reboot, force restart the device after the TWRP flashing was successful and immediately switch to the Recovery combo.
Here you go: two ways of doing this.
I am currently stuck between fastboot mode and recovery mode.
I was on latest stock rom before this happened.
When in fastboot mode:
1. Holding power button reboots back to fastboot.
2. Holding power button + volume up reboots back to fastboot.
3. Holding power button + volume down boots to recovery.
Now, in recovery also it boots back to fastboot.
With Red Wolf recovery:
1. I did factory reset and also wiped cache and dalvik
2. Then when I tap Reboot System, the screen freezes.
3. I hold power button and it boots to fastboot.
I then flashed stock recovery from fastboot and
With stock recovery:
1. I did factory reset and wiped cache partition.
2. Then when I select to reboot system, it boots back to fastboot.
3. Or if select to power off, it again boots to fastboot.
So basically, I can only toggle between fastboot mode and recovery mode.
I know very little about all this so please help... I think its bootloop and I want to be able to use my phone again.

Did u flash a custom ROM over ur stock without wiping system ?
Do this :
Flash redwolf recovery via adb.
Download and copy custom ROM n gappsto ur ext SD .
Reboot to recovery.
Wipe system , cache. Dalvik , data .
Then install/flash custom OS then gapps , wipe cache n dalvik then reboot .
And that's not a bootloop

Install full flashble update by avinash 318 update. And reboot. Problem solved
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
