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.

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.

I usually release the power button on the boot screen first and then the other two buttons

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..

ODIN mode, potential brick

Hey there.
I am boarding an airplane in a couple hours so I am urgently seeking help.
I am using akop b25. I was installing a Google music apk and my phone restarted. It then went into a boot loop.
When I turn the phone in using power+volume down, it boots into a screen like fast boot except it says ODIN mode in red at the top, under the android picture it says downloading.... do not turn off the target. The only thing I can do from here is battery pull or press the power button to activate "start", which just boots the device and back into boot loop.
Can anyone help me with this situation. Thanks alot

Try another button combo. Volume up and power button?
In recovery, reflash the rom. I'm not sure though how an apk install caused boot loops.

To get to fastboot the button combo is Vol Up + Vol Down + Pwr. From there select recovery and reflash.

Wow, epic face palm. I could have sworn fast boot was volume down only. Okay, I should be fine then.
Thanks a lot guys

Galaxy Nexus cannot boot into fastboot-bootloader.

I was in recovery and suddenly my phone died while i was installing Cyanogenmod 10.1.
Then i tried to charge the battery and boot into fastboot by holding +/- volume and power buuton, but the phone would just boot normally.
The installation of Cyanogenmod 10.1 had not completed, so i was stuck at the Google sign.
Is there a way to get into fastboot-download mode or in recovery?

Have a read here.
Hold volume up and volume down, and then press and hold power.

I did it but again it took me to the Google sign.

are you pressing and holding both vol up and down and THEN pressing the power button and continuing to hold the vol buttons?

I know the command sir, im just asking the other user if he can go in fastboot via adb.
At the other hand, no problem from bumping old thread with same subject. It is better than open a new thread

[Q] Can't get into recovery after rooted and flashed CM10

I rooted my Galaxy S II t989 and used goo.im to install the recovery program (whichever it found compatible with my phone) and Cyanogenmod 10. I flashed CM10 from goo.im, and the phone backed up and rebooted to the the cyanogenmod screen. It was stuck there forever (over 30 minutes), so I pulled the battery and tried to get into recover mode, but no dice. I can't get to recovery mode, and it just goes back to the cyanogenmod screen.
When I hold volume up, down, and power it'll flash the "teamwin" blue screen, but then just go blank and if I keep holding volume up, down, and power, it'll just pulse the vibrator every second until I let go (forever if I just keep pressing). When I let go, it just goes to the cyanogenmod screen.
I'm kind of at a loss here, and I'm afraid of bricking the phone. What can I do?

I think I figured out how to get into recovery. If I take the battery out and start holding the buttons before I put the battery back in I can get into recover. I am now flashing stock. But if I couldn't get into recovery or download mode how could I flash anything with Odin?

The easiest way to get into recovery is to shut your phone off, press volume up and down buttons and power. When you feel it vibrate let go of the power button only.
For download mode turn off, press both volume buttons and plug phone into computer.

How timely, I thought I had seen something weird before with releasing the power button.

[Q] My LG Optimus G is only showing Fasboot mode

I was stuck in a Boot loop at first I got it out of the boot loop and back to functioning properly but it was changed from my sprint to At&t, but that didn't bother me....lol.. I guess it should have. long story short... My phone is only showing fastboot mode. I cant get it to do anything else. What can I Do?????????? on the fastboot screen it says
PRODUCT NAME-Mako
VARIANT-Mako 32GB
HW VERSION-rev_10 (232)
BOOTLOADER - MAKOZ10f
BASEBAND VERSION-N/A
CARRIER INFO - one
SERIAL NUMBER - ################
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - unlocked
and nothing more......

try to power off your phone completly by holding the power button for roughly 15 seconds or so. after that try to boot it normally by just holding the power button a few seconds until screen turn on. if that gets you to that "fastboot" mode (the bootloader) try to hit volume down twice then power. recovery should boot up. from there try to clear data and reboot.
