LG G5 can't boot into recovery. - LG G5 Questions & Answers

Hey everyone (Again),
So i managed to unlock the bootloader and everything went smoothly but I flashed my recovery i can't get into it now it comes up with an error message everytime i try to get into recovery it says ' Your software cannot be checked for corruption' any way to get rid of this or do i have to re- lock the bootloader just to fix it and get recovery working.
Thanks again.

That's not an error message, that's the message you'll see every bit if you unlock the bootloader. Do NOT relock your bootloader after installing custom recovery. Also to get into recovery (provided you installed it correctly and it wasn't erased after it booted info Android) is to turn your phone off (or pull battery) and then hold volume down & power button, one you see the LG logo let go of the power button only (still hold volume down) for about 1 second and then press the power button again and hope (never let go of volume down). It will ask you if you want to reset your phone, select yes two times and you will enter TWRP. If it actually resets your phone, TWRP isn't installed. Usually after installing TWRP you need to pull battery then use above method to boot into recovery, mount system partition and use TWRP file manner to delete come named "recovery from boot.p". You can also go ahead and install SuperSU or magisk (use magisk if you need to be able to pass safety net). Hopefully this helps you, also next time please include what model phone you have and what steps exactly you did as it's easier for others to attempt to help you.

Mines a H850 running nougat as well but thats the only thing it wont boot to recovery because when i hold down the volume down button and the power button the lg logo shows up but then after 4 seconds that google message will pop up and that gets in the way of doing the method to get onto recovery thats my problem

You have to follow exactly what I posted earlier. If you do that, it will show the factory reset screen which is you have TWRP installed, it will not into TWRP.
1) Power off phone
2) Press and hold volume down (do not let go until you see factory reset screen)
3) Press and hold power button, when you see LG logo, let go of power button for 1 second and then press and hold again.
If you do not follow step 3, you'll never be able to boot to recovery using button combo, it will just go to that message and then boot into Android.

Thanks for that! I got it working cheers

I'm actually having a similar issue too.
To clarify, I'm using a LG G5 (h830 variant) that is running resurrection remix.
I remember getting into recovery just to flash the updated modem and bootloader zips so I can fix the issue with powering off the device.
Now I noticed after doing that, I cannot get into recovery either with rebooting or with the button combo.
Thankfully I am rooted with magisk and this is probably the first time that I encountered this issue.
I don't want to further risk anything (because my phone is set up and don't want to lose any data) but would flashing twrp through the official app work just fine?

I know this is old,Just wanted to say thank it worked for me...
Been a while since I used LG and never with official bootloader unlock so I was thrown off by resetting to recovery as at first i never had the lg screen just the bootloader warning start

For those T-Mo G5 (H830) with unlocked bootloader, you will not see any LG logo. Once you see the lcd backlight comes on, immediately release the power button and press it again, all the while holding down the vol down button.
When you see the bootloader unlocked phone is unsafe msg by LG on the screen, it will already be too late and past the stage where you can boot to recovery. Simply power down and redo in that case.
(Needed to do the above as the latest Magisk 20.0 broke root and adb on H830, thus there was no way to get into recovery other than using the physical buttons. The Magisk Canary version of 20.1 works though.)

Can't get into TWRP recovery from boot

I'm a bit of a noob at terminology and android settings so try to bear with me...
I'm running a deodexed vzw CleanRom v1.6.5 and I've downloaded TWRP recovery via gooManager. (Yes I've installed the recovery script from it.) Back when I had a stock rom, when I held the power + the volume up button it would go into TWRP recovery fine. But now (I don't know if it's CleanRom's fault) when I start up the phone into recovery mode using the shortcut the blue text would appear but it would restart normally.
My stock backup was corrupted for some reason and it softbricked my phone so I had to odin flash and go through all that rooting process again before restoring from my CleanRom backup via TWRP. So I don't really want to go back to stock, but I guess I can download a stock one if I really need to.
I can still enter TWRP by going into gooManager and pressing reboot recovery from there. Any solution to this?
I'm also on CleanRom 1.6.5 and it works for me... Vol up+power
Sent from my SCH-I545 using xda premium
To get mine to boot to recovery while phone is off I have to hold volume + and menu key at the same time. Then hit the power button until it vibrates then let go of the power button. If I keep holding the power button then the blue writing is displayed but instead of going into recovery it just reboots. However if I only hit the power button and release when it vibrates and I am still holding the volume + and menu key then it will boot to twrp recovery.
Alright, I'm feeling pretty foolish.
It was a simple user error that I really hate to admit. If I hold down the volume up and the power button and keep holding down both, the phone restarts as normal. But I should be letting go of the power button when the phone vibrates, while holding down the volume up button keeps it loading into the recovery mode. Don't know why I didn't have that problem before. I attempted Travis' idea first then experimented a little without the menu button and it worked fine.
Thanks.
Glad you got it figured out. :good:

True and that is what he said he has been doing. However what if you flash something and you get a boot loop. You can pull the battery and try again but if it boot loops again you will need to be able to get to your recovery with a non booting phone. That is why it is important to know how to boot the phone into recovery with out the need of any apps.

Precisely my thought process. I knew that at some time I'm bound to softbrick my phone again and I needed to boot recovery from startup.

Unable to boot into TWRP recovery using power/volume-down button

Hi,
I have LG G5 H830 and I have installed stock ROM 20k with TWRP and root. However, I can't boot into recovery using the combination of these buttons.
The instructions I found says: 1. held both buttons 2. When LG logo shows, briefly release both and then press and hold again, till recovery. Since I have unlocked bootloader, there is a warning after the logo appears and it will continue in a few seconds and showed the logo again. I tried to hold till the first or second logo but I could never get into recovery.
Another thread suggested to only briefly release power briefly and always hold down volume-down. This worked except it went into factory reset (the only option is to reset or now).
I can use adb boot into recovery and it's TWRP.
What am I missing here?
Thanks

You must tap twice yes for factory reset than it boots into TWRP when TWRP is installed properly

how to fix bootloop?

hey, i've got a problem.
i'm running on Oreo 20r and installed Magisk using TWRP.
after rebooting, my device stucks in a bootloop.
is there any solution for my problem?
flashed magisk 17?
yes...
okay, actually I am currently stucked with the same issue too.
But I just got back my TWRP by doing following :
1) Boot into download mode (https://www.youtube.com/watch?v=_mycJDiFUPk)
2) Still in download mode, press and hold "vol down + power" (this time USB cable is still connected to PC and phone), it will reboot the phone, hold both button till you get in fastboot mode
3) once in fastboot mode, flash back TWRP as per unlocking guide
Now I am still in TWRP, hesitating what to do next. lol
Hope it helps a bit
it's not possible for me.
my device reacts to nothing... no keys, no recovery, no download mode
bootlooping like no tomorrow
maybe you can install KDZ-file using LGUP
or try to flash ZIP-file

I just clean flashed back Boombox 1.3 with magisk 16.0, so far booting up good.
I think you need to try again.
The download mode is a bit tricky, need to very fast hold long power button till off, once off, hold the vol up and connect the USB cable to PC. it should trigger the download mode
The bootloop that you have now, is just "LG V30 ThinQ" and the "unlocked bootloader" msg right? same as me I think

okay, let me try describe my steps in details :
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC
4) Now it should show the "download mode"
5) Without removing the USB cable, hold "power + vol DOWN"
6) Once screen becomes "black", release the "power" button, hold the "vol DOWN"
7) Until you see the "fastboot mode"
8) Now you can flash TWRP back using fastboot command from the PC
9) Boot back to TWRP
p/s : yes, the phone cannot be turned off, for long time, but it can be for a very short time. Need to use that short time to trigger all the keys
I have the same problem after flashing Magisk 17. I am in a bootloop between LG black start and root/unlocked bootloader warning screen.
I followed your steps 1-7 in a command line screen (as administrator) and it works but it seems that recovery flash is not working because the command line screen show me a very short time in the recovery flashing work (see attached image).
"fastboot reboot" returns me to the bootloop.
"Power Off" and "Restart" options in the phone returns to me to the bootloop again.
If I unplug the USB cable in the fastboot screen, the phone goes to the splash black screen and does nothing.
WTF!!! it's working.
i tried it one more time like you described it.
think i did it too slow before. booted into TWRP and the rest will be no problem (i hope so).
thank you sooo much!

how did you reflash Magisk 16 after?
@ChazzMatt HAve you looked at this? Some of are having issues after Magisk updated the Magisk app and then lost root...I guess we shouldnt have flashed 17, but when I try and reflash 16 I get the "updater process error" does that mean my only option is to format SD again, or do I have to start from scratch?

No, see the last few posts of WTF thread. You just have to uninstall 16 first.

I am stuck with the same kinda issue. By mistake restarted the Phone after wiping the phone for a fresh rom install. now i can see only the LG boot logo. There is no way to power off the phone. Pressed the power button alone for couple of minute but no use. Tried pressing the Vol Down and power to restart. I get a 1 sec window when the phone is off between the restarts but your method does not work in that short time. Is there a way to power off the phone ?
basically there is no Rom on it and does not detect on the PC when plugged in
Please help if you know anything

Try going to TWRP
1. hold vol down + power till it off
2. Once it shows the first on screen, release the power button and press back the power button (vol down hold)
3. A menu for factory reset will be shown, agree to it 2 times
4. Then it will boot to TWRP ( no data will be deleted )

Stuck in recovery mode

I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!

Build.Prop edit mistake

Long story short, I messed up and I regret it. I edited the SDK 2 API levels up to get an app to possibly work and didn't think of the consequences of everything else.
I was running 8.0.0 rooted and am unable to get into recovery as the main boot of android is messed up where all apps result in continuous errors and when trying to enable usb debugging in the settings, the settings crash.
If I could get into revovery mode, I can fix it. The issue though is holding power + vol down does not work. I am not sure how to get into the recovery when the v30 shows that conformity screen on boot when the boot loader is unlocked. I was able to get into fastboot mode but on that screen it says i need to enable OEM unlock. Sadly that is not working as settings crash when trying to enable.
Would anyone have any other ideas to get to recovery?
Let me know if any more info is needed.
EDIT: I do have LGUP installed and does see the device. I would prefer not to have to fully reset the device if possible. Can LGUP boot the device into recovery?
What you described (just holding power and volume) will not get you into recovery... the proper sequence (aka the "button dance") is more involved than that. If you're only holding down those buttons, then you're not doing the process... do a search to see what it is (I believe you need to release and then re-press the power button... but I don't recall, so certainly don't take my description as enough info.
You also said you can boot into fastboot - you may be able to "fastboot reboot recovery" to get into recovery... some phones respond to that.

LGUP can get you to Download mode but not Recovery.
You can boot to Recovery (TWRP) with hardware button dance.
8 sec Power + Vol-, and when it shuts off, release both, immediatly press both again (at the same time), and as soon as the LG V30 logo appears, release power and press/hold it again.
Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons), and TWRP should boot fine.
Might take a few tries to get the right timing for that

For that, remember the annoying bootloader unlock warning is part of the boot sequence, if you still have that.

@schwinn8 -
I ended up doing a clean flash with LGUP as I need my phone for work and thought this might as well be a good time to update from stock oreo to stock pie. I wish I had remembered the master reset method as that should have throw me into recovery, I was releasing and then holding both power and vol down when it should have just been releasing power and then holding while continuously holding vol down. Along with fastboot, a while back I had to reinstall windows and so not thinking things through, I did not have working fastboot drivers and didn't initially realize it.
Mistakes were made :/
I very much appreciate the reply.
