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..
Long story short i rushed when rooting my GN because im pretty familiar with rooting android phones. I did not realize you needed to modify a file to be able to boot into CWM other than using rom manager.
My question is, is there a way to get the stock image on the phone, or, use my computer to fix this? Because currently my phone is in a bootloop (I installed gummynex improperly, rushing and forgot to wipe data, yeah i know i asked for it.,..)
If i boot into recovery all it does is let me turn the phone on, i cant select recovery or anything.
HALP!

Thanks but one last question, I can only boot the phone into the stock bootloader (whatever the default thing is when you hold the power button and volume down) and in this, the ONLY option it gives me is to start the phone, nothing else
Am i going to be able to push files to my phone in this?
I think this may have just been a MAJOR blonde moment for myself. in order to access CWM and ****, you have to hold both volume buttons and the power button? Because i was just holding volume down and power....

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.

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
I guess google can save lifes And nerves!!!!
Cheers bro
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

So guys I would really appreciate some help on this. I dropped my phone the other day and a very minor crack happened on the corner of the screen. Now every time I turn on my phone or reset it, it says that the phone has detected screen damage and goes on "Hardware Key Control Mode" and everything is disabled.
The rest of the screen looks totally fine and the crack is on the bottom corner where the hardware keys are, and those keys work fine as well. I believe the rest of the screen still functions but I cant remove this mode. I turned off the phone and pressed all 3 buttons and then tried disabling it but it goes back into "Hardware Key Control Mode" after restarting. Is there a way I can remove this somehow? I dont mind flashing if necessary. Would REALLY appreciate any help, thanks in advance.

Your phone is likely detecting a damaged digitizer. The screen will be unable to detect touches even if you could disable this mode.

Hmm is there any way to disable it though? Because the hardware keys that are on the screen where it is cracked are working fine... also on the log in screen when you swipe to unlock I can see the background moving when i swipe over it.

I'm not aware of any way to disable it outside of flashing a custom ROM. Do you have TWRP installed, and if so, can you use your touch screen in recovery?

No I did not install TWRP yet. Should I try doing it now? Will I need any touch screen features while doing it?
I installed TWRP on my phone using the phone itself. I don't think there's any other way to flash it, but i could be wrong.

Oh ok, thanks for your help. I will give it a go tonight, some people are saying you can install it using ADB driver commands from cmd prompt. I just hope that after installing a custom rom the Hardware key control feature will go away, because I was reading somewhere that it is stored in a different partition or something.

Hey again, So yea I tried everything . Im trying to use the ABD cmds but since I cant swipe on the screen its not letting me to press "allow" for usb debugging mode, so i cant root then install TWRP .Im stuck here. Is the phone garbage because of this "Hardware Key Control Mode" ? I cant find any way to turn it off or remove it completely. The screen only has one minor crack, and that location near the hardware keys is working fine.

Any one else know what I can do about this issue? there must be some sort of workaround? it is a software issue.
I've been trying to root this phone and I was trying to flash it with a modified boot.img which I did, but now the phone just keeps on restarting. It briefly shows the splashscreen and then reboots again. I can't seem to connect to it via adb, I also tried using the Lenovo recovery tool but it can't seem to connect to the phone. I found that by pressing the down and up buttons it takes a lot longer to reboot. I see the splashscreen and then it goes to black for a while, and then reboots. If you have any idea what could I try I'll really appreciate it!

Hold the volume down button, and press the power button.
This should get you back to the bootloader screen, then LMSA should detect the device.

Well, it can be a little tricky.
You should be able to press and hold both Power and Volume Down buttons, till you see the bootloader screen.
But I usually have better luck if I hold the volume down button, and only press the power button till it seems to be powering down before rebooting.
also can try doing this while connected to PC or wall charger.

Are you 100% sure I don't need to also press the upper button from that same row right? Because for booting into fastboot without using the command was by pressing those three buttons at the same time. I've been trying both ways with no luck still.

I'm sorry, it's a Moto G20 X2128-1.
Yay finally managed to do it! For the record I only had to use the volume down key and plug the usb cable to the pc just at the right time (right about the splash screen disappears). Guess I'll wait until someone post the exact method to gain root. Thanks @sh_shadow!

Did you verify that the version you had on the device, was the same version LMSA downloaded?
If LMSA had a newer or older build number, the boot.img may cause a bootloop

Yes, it was obtained through LMSA so I'm not sure exactly what was the problem. I side effect I'm facing now is that the phone takes forever to start, quite weird!
EDIT: The only thing I can think of is that I flashed boot on fastbootd, maybe I should have flashed it on the bootloader.

No, LMSA downloads the newest build on that server.
That doesn't mean it's the same build number that's on your device.
If it's a different build number you need to flash the lmsa version, or the boot.img may not boot correctly.
