Booting to recovery with button combination not working

So, after trying out a few firmwares (JM2, JG8, JM5) and kernels (Samset&OC) I can't no longer boot to recovery with Vol UP + Home + power. I can't really say when this problem first occurred, but maybe with JG8 flash. The strange thing is that I can get to recovery with adb reboot recovery and through android console with reboot recovery (when rooted ofc). Also download mode works great.
Things I have tried:
-flash again to JM2 and JM5 with re-partition checked (512 PIT)
-cleared cache+data through recovery
-factory reset through phone code (this also cleared the internal SD)
-took out the battery multiple times
-booted phone without sim
-flashed phone without sim
-changed CSC with phone code
-restore a nandroid backup of JM2. Recovery worked with this one when I took the backup
-there's no external flash card inserted
Soooo..does anyone have any idea about this kind of problem?

i had a similar problem after trying few ROMs. In my case, when i pres the key combi i get the boot logo and then few seconds later the screen goes black and then i see the boot logo again, and this goes forever. and then i tried pressing the same key combination simultaneously and once i see the boot logo i let go the power button and keep the vol up and home pressed, and then only it went into the recovery mode.
hope it works the same for you
Cheers

Agreed, 99.9% chance you are doing it wrong.

mmthabet: I had the exact same experience. Letting go of the power button when the logo appears lets me enter recovery.

or you may need to take out the battery first for a few seconds... after that, you can reinsert it back and try recovery mode...
at least this work for me...

Thanks for replies but none of the solutions work. The recovery mode button combination DID work for a few weeks, but then just stopped working.
I know that I'm doing it right. I have always pressed vol up and home down until the phone loaded recovery and only briefly pressed power button just at the start. I have also tried to remove battery multiple times and once waited 30 mins before re-inserting it.
Trust me, I'm not doing it wrong :s And recovery is working great through adb reboot recovery and shell.

More so a timing issue. Buttons not pressed at the same time.
I get it all the time for all combo's.
Just keep trying.

You might already have this however just in case you dont, check out Quick Boot.

With this app you can boot into recovery mode. Have to be rooted though.

this wont work, if you bricked the phone in a bad flash situation.
in times when this app works, you can easily do adb reboot recover
so this app still doesn't address the real issue of how to get the 3 buttons press hardware recovery mode

I release the buttons right when the first Samsung texts comes on the screen. It will take it to Recovery mode. I also had a "boot loop" few times, if I keep pressing the buttons all the time.
Have you tried release your fingers right in the first texts? I really don`t know what is exactly the right way to press the buttons, but this always have took it to Recovery.

Looks like my latest full wipe with *2767*3855# cured it. Flashed JM5-->full wipe-->samset1.9b-->samset kernel and now it works. It must've got stuck somehow in my previous JM5 installation.

I cant get into the download- or recovery-mode by using these keys... so i am not able to flash a new firmware! can anybody help me please? is there a chance to get into the download mode by using an adb-command?

yes
adb reboot download
but it is dangerous, as you can not recover from a bricked state, if your flash is not compatible or if something went wrong with odin, etc.

I you're bricked and can't get into Download or recovery mode, leave the device to boot, it will just show a black screen for a while then will turn its self off, once this happens you should be able to use the key combo.

Any idea how long you waited? Been waiting 5 minutes, hasn't shut off. Mine's a Bell though so I'm guessing I won't have any luck.

The way i do it (no chance of doing it wrong and timing):
hold down+home and then also press the power button for a little more then 10 seconds (so all 3 buttons for 10 seconds). The phone will reset into download mode, never fails in whatever mode the phone originaly was..

[Q] Acidentally Wiped System, What can I do?

I accidentally formatted the system partition so the tablet will not boot. I can't get back in to TWRP, I didn't have anything to flash in there anyway because CM would fail. What can I do?
Thank you.

You could try the LG mobile support tool

I realize why it didn't flash. Because I was using an older version of TWRP that wouldn't flash AOSP roms. Is there any way to boot to recovery from the device being off?
The method in the link doesn't seem to work anymore.

How far do you get in the boot? LG screen? When connect to PC do you get connect/disconnect sounds? Please answer the questions as I'm thinking about this. I can't find any key combos so we need to find out if we have a small window where we can talk to ADB.. Any connection sounds? How far do you get?
Are you familiar with ADB and Fastboot?

I don't hear any sounds. It just stays at the LG screen. I made it to the factory reset screen but it didn't do anything. I followed these steps:
Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

Okay, okay, I dunno what you can do maybe ADB Works in here: Turn off the device AND disconnect from PC. When shut Down, you DONT hold power, but hold Volume up + Volume Down, when you hold both, you plug in USB cable. This takes you to download mode. That is perhaps a step in the right direction if you can start ADB from download mode. Then you can boot into recovery. But I don't know. This is maybe the last option for you. No recovery key combo has been discovered yet. If you can do a fastboot boot recovery from download mode, that would be golden. Then you can use the SD Card to get back with the newest TWRP and the CM11 nightly. Please let me know if this Works man. I'm sorry for your loss, otherwise. Factory Reset, as you said, will not work, since there's nothing to "restore" from. You deleted it. :/

Unfortunately, ADB doesn't work in download mode.

Damn that sucks. I was looking around the G2 forums to see about download mode and what LG usually did with it. Apparently they are using something called KDZ files, and they are able to flash stock roms back onto the device with something called FlashTool. Now, if it were my tablet and it was in the state yours is, I would try and read the tutorial. And then I'd follow it step by step but instead of the G2 KDZ, I'd see if I could find a KDZ with a G Pad rom instead. And just.. Yolo that ****.. From download mode.
Here's the thread, if you wanna read it.. http://forum.xda-developers.com/showthread.php?t=2432476. I dunno man. The LG Tool thing, maybe you should try and see what techrider6262 is saying, he might have an idea as well, otherwise, just go all out crazy and see if you can magically use the FlashTool on your G Pad instead of the G2, since they are from "same line up." I know that's not the same as same model and so on.. But still.. Download mode.. Is download mode. Ofc. the tool itself or the settings in the tool might not work.. But.. You know. Why not.. Can't hurt.. Download mode will prolly still be available afterwards.. "For science."

got the same problem. i couldnt i wiped all data on the tablet and couldnt select the rom from the ext.sd. now its stuck at the lg logo.

This guys.. Is for download mode fix. I am pretty sure this works. Since you have access to Dload mode. Good luck.
I use the download mode to install the original official rom.
1. Download the LG MOBILE SUPPORT TOOL by this link:http://www.lg.com/us/support-mobile/lg-V500-White
2. install the software in computer, Plug in USB cable with computer, Open the software LG MOBILE SUPPORT TOOL.
3. Turn off Pad and unplug.
4. press hold both volume up and volume down, Then plug in usb cable, And then pad is in downlaod mode
5. USB driver will be insatlled automatically
6. In LG MOBILE SUPPORT TOOL, click option---.country and language-OK, then click option--upgrade recovery
7. It will installe original official rom automatically.
8. After about 1.5 hours, The pad will be installed the last official room.
^ This is a quote and now I shut down the thread, sorry, don't know who said it, just got stoked when I saw it.

thanks, the tool is downloading the rom. hope its works.
// it worked thanks a lot, will try to flash cm 11 tomorrow again.

That is GREAT!
Now remember mate, clear DATA in TWPR, not system.. Never system. Clear only data/factory reset, then just flash CM 11. Nothing else is needed. Remember to install superSU from market after you get booted, otherwise root will not work. Update Binary in SuperSU.

Okay thanks for your help. Its so stupid that there is no key combination for recovery.
I will use your advice and try it later.

There is...
With device powered off do this...
Hold volume key down and press and hold power button.
When LG Logo appears let go of just the power key while still holding the volume key down and then press power key again and volume up while still holding down the volume key.
You get to the factory reset screen and just keep pressing power until you get into recovery.

[SOLVED] How do I boot into stock recovery?

From a full power off, how do I boot into stock recovery? I've tried multiple button configurations and none work.
EDIT:
I called T-Mobile and they said:
1. Power off
2. Press and hold the Vol - and Power button until the LG boot screen appears.
3. Release the Power button ONLY. Do not release the Vol - button.
4. After 1 second, press and hold the power button again. You should see the white recovery screen.
Use the Vol+/- to navigate and Power to select.

This brought up a Factory data reset menu on my H815.

Brings up factory reset on T-mo version H-811

That is the LG factory recovery.

thank you this worked

With a Verizon model, I had to keep holding both Power and Vol - until the recovery screen appeared. If I released and then re-held Power, as described above, it did not work.

When I hold down power and vol down, it boots to an IMEI display screen. It shows a long barcode. Can't get to recovery with the hold, release and hold down again the power and volume down buttons. Frustrating.

I love you so much right now. It boots into what appears to look like a default LG G4 factory reset page. For me, i clicked reset, and then yes, and surprisingly it brought me to where i wanted to go. TWRP Recovery.

THANK YOU!!!

The difference was that you have twrp recovery and he didn't. The question pops for both, but for those that have the original recovery it will do the factory reset.

worked for me, but the first screen is the one where it ask if i want to factory reset, i had to pick YES, then again confirm, and then i was in TWRP

And I get a factory reset as well on my H811, even though TWRP was already installed and working on the recovery partition.
Something else funny going on, the OS seems to kill TWRP after the next one or two boots tho. Maybe I need to set the TWRP option to allow change of the system partition to read/write? (Since apparently it writes something there that prevents the OS from killing the custom recovery after it's been installed)

I've learned a lot with LG phones over the past few weeks.
The biggest thing is.. when you first flash over TWRP, you HAVE to reboot into recovery before you try rebooting the system, or else the bootloader will overwrite the TWRP install and replace it with the factory recovery.img. (You probably already know this.) To make sure it boots into TWRP first, since fastboot doesn't have a "reboot-recovery" command.. I just pull the battery then do the button combination to boot directly into TWRP. Doing this allowed me to say "YES" to the question "Do you want to factory reset the phone".
I don't know how many times I've wiped my phone because of this:
1. flash TWRP.
2. reboots (tries to hold the finger combo but failed - and didn't know it)
3. gets asked question - "do you want to factory reset the phone"
4. I hit YES expecting it to take me to TWRP - but instead it wipes the phone and puts stock recovery back on.
Just do this:
1. flash TWRP.
2. PULL THE BATTERY
3. Use finger combo to boot recovery.
4. When asked "do you want to factory reset the phone" - hit YES
5. TWRP boots in like 5 seconds.
This has worked now for my G4 and my V10 since they both have this issue. The V20 however does not (my current phone) - so hopefully LG is done with this crap!!
Good luck!

What was happening on my H811 was that it was either corrupting the recovery partition afterwards or just invalidating it or something because instead of getting back the stock recovery, I'd get the scary "broken robot" screen when trying to boot into recovery.

The technique I've learned to appreciate (which apparently is a new thing, and is now the suggested method for installing via fastboot according to the twrp.me website) is to load a copy of TWRP into RAM to do the flashing and rebooting. ("fastboot boot [TWRP_IMAGE_NAME]")
I try to avoid battery pulls as much as possible but I have never relied on them on a phone the way I have done over the last week (just had my G4 for about a week now) due to these funky mechanisms that LG has for getting into recovery/bootloader/download mode.

TBH I am fearful of even trying it now. (Especially since I just read about how a nandroid backup done from TWRP doesn't backup anything on the /data partition, either.. )
Which makes me even more appreciative of LineageOS's "advanced reboot" power button menu. :good:
One of the problems in my view with this LG system is that it can be very difficult to reliably press both the power and volume at the same time on this phone due to it's unusual placement of those buttons. Much harder than on a phone with those buttons on opposite sites of the device. Not to mention this silly "press both these, then release one, then 1s later press that one again" stuff.
And due to the way they designed these sequences, which among other things often have no way to easily escape them (can you imagine having this on a phone with a non-removable battery?? ), but worse, have defaults that progress to another state without any user interaction (because of the limitations of this control logic - eg, if you boot to bootloader but can't escape and don't do anything in 2 minutes, the device automatically reboots), I personally have to wonder if this doesn't make a significant contribution to the infamous bootloop issues that lots of people are having with recent LG's like the G4, G5, V20, etc.

Enter recovery on 20B?

Hi, I'm having a major problem getting into recovery via the power-on+vol-down key combination on MM (20A/20B) - under no circumstances can I get into recovery from cold boot - I can reboot into TWRP recovery when the phone's booted, but recently I've had a couple of bootloops which never enter the OS and so I'm stuffed - both times all I could do is use LGUP to reflash 20B kdz and then re-root etc etc. I'm assuming under MM the key sequence has changed, or is it because I have an unlocked bootloader the sequence is different? I've owned a G2 and G3 and know the "normal" sequence of hold power+vol-down, wait for the LG logo and release then power+vol-down again, but this doesn't seem to work on a Marshmallow G4 (I've tried 100 times with different wait periods on the release etc)....
Its a real PITA not being able to cold boot into TWRP/recovery so can someone advise what the sequence now is (and PLEASE don't reply to tell me its "hold power+vol-down, wait for the LG logo and release then power+vol-down again"!).
Thanks!

I have the same issue and I had been running into same situation to entirely reflash my phone in order to get it boot again. The key combination never worked for me while on 20B; really frustrating if you run into whatever problems requiring to recover through TWRP and not being able to do so.

key combination working me....
If not
adb reboot recovery
Or if phone rooted.
Play store rebooter app

And it never came to your mind, that maybe the entry to recovery might be different to an LG G3 or G2?
The way to enter recovery is:
Hold Vol- and Power until LG Logo appears
Release ONLY Power button for 1 sec
Then press it again and hold it
Recovery entered

EDIT: Btw this has nothing to do with Marshmallow, Lollipop etc. It's the usual way to enter recovery on a G4 And I didn't read the OP entirely. It seems like you just had the wrong sequence. This one works for me on Masrhmallow 20B!

Thanks for your heads-up. Unfortunately if i try this combination a screen appears "Factory data reset" asking "No (Exit)" or "Yes".
Now I would assume if I enter "Yes" it would boot into recovery, but I am not sure whether this will completely wipe my phone.
Can anyone confirm that I´m on the right path here?

Hold on. There are 2 options. If you installed recovery properly (I bet you did), indeed, clicking on "yes" will boot you into recovery. If you're a monkey, just like I was, and DIDN'T install recovery properly, yes, it will just wipe your data.
But that's the usual way to hardware-button-boot into recovery
How did you install it? There's an easy way to check if everything is set up correctly. Use this app to boot into your recovery from within android.
If it boots you into recovery then everything is set up straight and you can boot into recovery with hardware buttons a 100% by clicking "yes" and "yes" in the "stock" recovery.
EDIT: I know that's an awkward way, but it's the right 1 Cheers

If it boots you into recovery then everything is set up straight and you can boot into recovery with hardware buttons a 100% by clicking "yes" and "yes" in the "stock" recovery.
EDIT: I know that's an awkward way, but it's the right 1 Cheers

Recovery-mode only, is there any hope?

[SOLVED] Download mode can't be removed, I had to try all dat long but I finally could boot into it.
Hi,
So... I had a working Samsung Galaxy S9 (SM-G960F/DS) running Lineage OS yesterday. I noticed something wrong related to the mobile network in my country (FR) and decided to flash the correct stock firmware matching the country code XEF before doing a full LOS reinstall.
Fast-forward 20hrs of download, I perform the flash operation this morning using heimdall(1) and reboot.
Now, the phone bootloops. I can't get into download mode as usual, and the only thing that is available is the stock recovery mode that allows:
apply update from adb
apply update from sdcard
wipe data
wipe cache
mount /system
view logs
run graphics test
I have a working all-countries firmware archive that contains the one that was working previously (minus the mobile network problem). But since I don't have download-mode anymore I can't install it. I tried adb sideload (which is available via the "apply update from adb" option), wipe data/cache to no avail.
Is that hard-brick? Did you ever experience a similar situation? I think there's no way out of this but any advice would be appreciated.
Thanks again!

You should be able to get into Download Mode (Vol Down & Bixby & Power)
Keep trying, try keeping hold of the button combo until after the phone reboots twice hopefully the second time into download mode
Download mode has nothing to do with firmware or recovery that has been flashed, and if you can enter recovery mode, it doesn't sound like a hardware problem either
And use a Windows machine & ODIN 3.13.1 to flash stock

Unfortunately it doesn't seem to work, i tried many tiimes and I usually can do that very easily. It seems flashing the corrupted images wiped it out.

Impossible as it is not part of the firmware, nor can be touched by firmware, it is part of the hardware (Think BIOS vs OS)
You can even 100% wipe all internal storage clean so there is no OS at all and download mode will still work fine
Keep trying

Okay I guess it's possible that the download mode is still there but I can't reach it.
I've been trying hundreds of times every combination I can think of (including Home + Vol Down + Power that used to work).
Any alternative way to trigger the download mode ?

How are you trying Home? There is no physical home button
The button combo is Vol Down & Bixby & Power from a powered off state
Keep a hold of all 3 until it hits the Warning screen, then hit Vol Up to enter Download mode
No other way to access it that I know of, USB Jig hasn't worked since a few models back
Have you tried factory resetting from inside recovery? Unless you used CSC during the stock firmware flash, that could be a reason for the bootloop

Yeah sorry, speaking of the Bixby button.

That's what used to work indeed. I did that many times before.

I tried factory reset/wipe cache from inside the recovery and yes, I used CSC.

Maybe the issue is with the Volume Down button, does it work inside of recovery for navigating the menu ?
What happens when you try entering Download mode? It just tries to boot as if you didn't press anything?
Only other thing is to hold Volume Down & Bixby, then connect the USB cable to power it on (instead of using the power button)

The volume down button works perfectly in the recovery menu.
When I try entering download mode normally while device is powered down, the phone never turns on.
When I try to hold the buttons during the interval of the boot loop, it goes to recovery (yes, even with volume down, not volume up).
The other technique you mentioned also went to recovery.

BINGO! I kept trying. Did this all day literally hundreds of times.
And it just worked.
I didn't change the way I do it, I think there was some nasty timing going on with the boot loop.
Anyways... lesson learnt: download mode is indeed hardcoded. What a day!
Thanks for being so helpful!

Good stuff, yea well whatever it was hopefully it's sorted now, use ODIN this time
