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.

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..

Try doing adb logcat while it is on the boot animation to see what is going on
Also try booting in safe mode

If you have an installed launcher try to uninstall it in safe mode. I had the same issue and it was because my launcher does not support Android Kitkat

i cant even get into safe mode
trying to get adb logcat
edit: it worked! i was pressing the wrong key thats y i couldnt enter safe mode
i was using next launcher, entered into safe mode, change the default launcher and it boots again
thanks!

I suggest you go and use @scrosler 's roms. They're the cleanest in my opinion

How to get into safe mode when nexus 4 is stuck at boot animation?

From sfhub's link:
power the device off then
Press/Hold Power button until Google screen shows up, RELEASE Power button
Press/Hold VolDn until Android has booted up
If successful, you will see Safe mode overlayed on bottom left of screen.

Any luck with this? My Nexus was running Next launcher and is stuck at finishing boot after the update.

Where can I do that? I can't get into recovery mode. I push "vol down+home+power" and it just says "downloading do not turn off target" Is there another place to factory reset?

I pulled the battery and it still just says "downloading.. do not turn off target" and won't go any further
But the strange thing for the boot loop in the top left corner it says "recovery booting" in blue and then its the android guy for a split second and then it reboots.

Pull the battery, then press volume down + home and power and see if you can get into download mode. Then press volume up and Odin stock tar.

I can get there but it just says "downloading... Do not turn off target!!" I have waiting for about 15 minutes and it doesn't change.

If I do volume up it goes into the boot loop. I was trying to make a backup with twrp and I think my phone is stuck in recovery mode boot loop

This is what you are supposed to see. Hook your phone up to tour computer, load the stock tar in the PDA slot, make sure you see com# ie. com6 and then hit start. It will flash the ROM and reboot your phone.

Pull the battery, insert and factory reset again. Pull battery again and Odin stock tar; pick one of the tars in this thread. The steps and tools needed to start are clear.
http://forum.xda-developers.com/showthread.php?p=56853325
Note: the thread was just updated for lollipop; the support posts and help posts are related to the KitKat tars. Original is last of the three. OB7 I'd most likely what you're after unless looking for Xposed framework compatibility which is KitKat only, for now.

[Q] P2a42 keeps stuck on first bootlogo

My dear P2a42 keeps stock on the first boot-logo :crying:
I've already tries to recover boot and system with TWRP 3.0.3 and TWRP 3.0.3-3. Also tried to wipe the whole phone and reinstall the ROM (the modded newest stock ROM), this also didn't work.
Strange problem IMHO... What's the best way to completely reset the phone to stock, flashing it with fastboot?? Or is there a possible other solution?
Thanks in advance :good:
Have a nice day y'all.

Lenovo p2a42 stuck on logo
Lenovo P2 is stuck in a boot loop.
I can't enter the recovery menu. If I press Volume up and power, it tries to start normally. If I press Volume Down and Up and Power, Phone enters "Bootmode is 'recovery'". After 14 seconds, it tries to restart in the normal startup.
If I press power + Volume Down, it enters a menu to swich between "Start", "Barcodes" and "Power Off". it shows dthe device parameters like serial number, storage, ram and the date of the installed software.
What can I do?

The only fix to get back into TWRP,
when the phone reboots, in the short moment of a blank screen you need to press Volume Up + Power.
The only catch is you have to press the Volume Up for a very short time.
It took me many attemps untill i got back into TWRP !!
Do not wipe anything or the phone boots again and you might get stuck in the same shizzle.
So install your favorite Rom & GApps and hopelly all works fine again.

I don't think there is one to force it to power off, I think there's only one to force it to reboot which is POWER + VOL DOWN (held down for a few seconds) on the A5, it's probably the same on the A3. Then immediately as the screen turns off you have to switch to the key combination for download mode or recovery. If if you just release the keys it will try and boot normally.

thx!! im in download mode now

Im in Recovery now. When i try to wipe it says it cant mount /data, /cache, etc.
Also Restore doesnt work because of this. I tried to Repair. System seems to be repaired, but /data fails to repair. Also unable to repair cache.
What to do?
(needless to say i first flashed the correct Recovery )
In Windows Explorer i see only external sd

Somehow i seemed to fix /data en /system. But not cache and dalvik.
I restored a nandroid backup and it boots until LOS animation now. But there its stuck. (but at least i passed Android logo now)
Installation passed pretty good, only in the end it said cache wasnt mounted.
Any ideas?

alright no clue how but its fixed now lol
