unluckily, I can not hard reset by pressing volume down and power
DO U have another method?
thanks!
for hard reset on stock cwm : turn phone off. press vol up + vol down + power.
I had the same problem. I even got worse and the phone wouldn't even turn on. So what worked for me is this:
I put the phone in download mode (Vol Up + Vol Down and then plug the usb)
After that I open LG Mobile Support tool. http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
Wait for the program to detect the phone then go to Options-> Upgrade Recovery. Wait for the process to finish.
After it finished the phone loaded normally and everything was intact. All my files and apps were untouched.
Hello guys,
I was trying to switch rom to my gpad but I rebooted without doing the factory resets so the new rom didn't boot up.
I've figured out how to reboot into recovery, there are 3 steps:
-with the device off press vol. down button and power until LG logo comes up,
-when you see the logo you need to leave the buttons and start pressing the volume up volume down and power button for 3 seconds
-then the device will boot into the reset mode, you have to press 3 times in a row the power button and then tadaaa custom recovery here for you.
Hope it can be useful
sorry for my bad english.

Friends,
I tried using the #3845#*855# and pressed DEVICE TEST and my LG G3 32GB restarted. It just boots up in miniOS mode and the screen is blank..
I tried rebooting and pressing the POWER AND volume UP button together --- RESULT - NO EFFECT
I tried rebooting and pressing the POWER AND volume DOWN button together --- RESULT - NO EFFECT
Any help is very much appreciated.
Thanks and Regards

THIS TRIC'LL DO IT, BUDDY..... SUGGEST NEXT TIME YOUSTAY CLEAR OF THE HIDDEN MENU THOUGH!!! UNFORTUNATELY YOU'LL LOSE ALL OF YOUR DATA..NO JUMPING THIS.
1. Start your phone up by holding onto both the power button and the buttom volume key. When the logo pops up, let go for a second, and hold onto both buttons again. This should bring up the option to reset your phone. Agree to both prompts.
2. You should be on a new screen. It may warn you not to touch the screen because it is calibrating or testing it. You will have to press OK, and then give it a few seconds to do that bit.
3. The screen should have a list of options at this point (some of which say "+power) on them. If you want to use any of these options, you need to hold the power button, and then press that option on the screen. Press "normal boot (+power)" (don't forget to hold the power button at the same time). This should put your phone back to normal, and set it up again just like it came out of the box.
ENJOY YOUR PHONE BACK
My wife's phone is stuck on the AT&T screen when booting. I am able to get into download mode, but am unsure of what to do next. I've downloaded the PC Suite and Mobile Support Tool (which seems to be more recent) from LG but in both cases when I do the update recovery I can't get it to work. The phone is totally stock, no root or anything, and as far as I know had the latest updates.
Can anyone help me bring the phone back from the dead?
This would probably work=
Ensure the device is power off.
Note If screen is frozen, remove/reinsert battery.
Press and hold the Volume Down button then press and hold the Power button. When the System recovery screen is displayed, release both buttons.
Select Factory data reset.
Note Utilize the Volume buttons to highlight and the Power button to select.
Select Yes.
Note Allow several minutes for the factory data reset and reboot processes to complete.
I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.
In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.
I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.
Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.
