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..

[Q] HTC Incredible Root...can't get into hboot, but will boot fine otherwise

Rooted my Incredible yesterday...with relative ease...some very helpful guides out there.
After searching a little...I can't find anything similar to my issue, and the pieces I can find don't piece together for me.
Was accessing hboot (power plus volume -) this morning and accidentally hit the power button to select "fastboot", rather than the "recovery" option i was wanting to get to to make another backup since I had added a few apps after my root.
My phone booted into froyo without any issue...and all my rooted apps worked fine (mainly wireless tether...the main reason I rooted). I shut down the phone and attempted to access hboot again...but got 5 vibrates and a green blinking led, with a blank black screen.
Pulled the battery...and let the phone boot normally (which I was hoping for since I thought I may have bricked it) and all is well...still with root applications working fine. I have tried hboot again with same result (5 vibrates and green flashing led), so I have let the phone stay with froyo for fear that if i screw around with it too much I may brick it after all.
Am I over-reacting to the lack of hboot? Suggestions for a fix are appreciated!

This is wierd, the only time ive heard this prob is when someone tries to flash a rom and then this happens. Sry man i have no idea its strange
Sent from my ADR6300 using XDA App

Download Rom Manager if you dont already have it a then install CWM recovery through it. It just sounds like it didn't install correctly the first time. That usually works for me when I get the problem of only being able to get into HBoot and Fastboot.

[Q] Bricked Desire HD

Hello,
I recently got a brand new DHD from T Mobile UK. Naturally, I wanted to get rid of the bloatware that came with it. To cut the long story short, I tried to install the cyanogenmod software and ended up bricking my phone. At first it would not get past the cyanogenmod start up screen (spinning smoke thing). Now it will not boot past the T Mobile logo.
I am desperate and any solution to give me back ANY funstionality of the phone would e great.
Kind Regards.
Sena.

Can you get into the bootloader? Try turning it off, then holding the power button and volume down - I think the easiest method is to hold volume down, press the power button for a few seconds (still holding volume), then let the power button go and after that the volume button. Seems to get me into the bootloader reliably.
If you can get into the bootloader, you should be able to flash back to the stock rom by placing a file on the SD card - not certain of the exact method there but someone will know
I wouldn't worry too much unless you were flashing the bootloader (hboot) to get s-off - as I understand it, the only real way to brick these devices is if you corrupt the bootloader.

What exactly did you do? I agree with the previous poster that you probably did not brick your phone you just need to get into the bootloader and flash a backup, if you made one. Also what ClockworkMod Recovery are you using. I know that if you flashed with 3.xxx you will need to flash an older version of CWM something like 2.xxx
If you give us more info we could prob help more

[Q] Alternative methods of accessing Recovery?

My Xperia Play has had a few problems out of the box, mainly that when I switch it on there is no boot animation, just a black screen. This means I can't access Recovery through the normal method of holding down on the volume or the back button etc. I've installed CWM through the CWM Xperia installer so I know it's there. I also ran the Auto-Magic Nandroid through that app, which caused my screen to go black (as it does whenever I choose to reboot through an app). When I looked on my SD card though there is now a Nandroid folder, so it's probable that the device does go into Recovery; I just can't see it.
So my question is this; is there any other way of getting my phone into Recovery so I can install some sweet, delicious custom ROMs? Maybe through ADB or similar? Or is it possible to install a ROM via another method?
Any help at all would be appreciated!!

If it wasn't working right right out of the box, I would have sent it back.
Can't you boot into recovery from the CWM-installer app?

Sadly that wasn't an option, it was the only one they had and I wasn't about to send it back for another type of phone, I've wanted this thing for ages
I've just clicked that option in the app and it's just rebooted the phone normally.

Turn on the phone, and when you see the notification light turn blue, press volume down for the locked bootloader cwm, or the back button for the one in DooMKernel.
Sent from a Galaxy far, far away

I've not yet tried installing DooMKernel, I'm worried that if I can't get into the normal recovery in won't be able to get into that one, then I'll be stuck with a boot looping phone.
Pressing down on volume on the blue led comes on doesn't seem to do much, simply stops the boot process from completing fully. I left the phone for 5 mins and got nothing. Pressing the power button again started the boot process again and it loaded up normally (minus any animations of ciurse)
It seems like stuff is happening, but I just can't see it. I doubt this is a hardware fault as the screen works perfectly all other times, so what the heck could it be!?

The recovery in DooMKernel is already built in, so it's different than using the Xperia CWM installer. By the way, the back button will get you into DooMKernel's recovery.

I'll give it a try and see what happens. Thanks for the advice guys!

[Q] htc incredible loop at boot up

hey xda

try a factory reset.
hold down -volume and hit power button. a menu should pop up and factory reset should be one of the choices

My incredible started doing this yesterday, Ive tried this option it doesn't work for me. I can get the menu but it when I choose factory reset or any of the other options it flashes the htc incredible screen and starts the loop again, any more suggestions would be appreciated.

Is your phone unlocked and rooted/s-off?
It will say so on that menu screen.

No I was getting ready to root it the day this started. Will rooting help this problem?

having CWM recovery on the device would help you clear the memory and load the OS easily. but that requires your device to be rooted.
whats strange about this case is that my understanding is that the OS is read only and the only thing that changes is data and user data held in a separate partition. so the 2 possibilities is that your user data is corrupted(probably due the space getting exhausted-were you getting a low space warning?) or less likely but possible-the OS corrupted in some way-perhaps from repeated reboots and phone use.
i guess if a factory reset isn't helping there is little i can suggest. that should do the trick if the OS isn;t corrupt because all it does is wipe away the user data so you can resetup the device as if you bought it brand new.
if you have an micro sd card in the device, try removing it. if that doesn;t work, try reformatting it and putting it back in.

This sounds quite a bit like an Inc I have lying on my shelf. It was a friend's and he gave it to me to see if I could fix it. As far as I can tell, the phone's emmc storage simply failed. These phones are aging and that happens sometimes. Anyway, I tried all the usual stuff, including running RUU's (flashing signed PB31IMG.zip's since the thing had never been rooted and was still s-on), and yeah, just boot looped.
I did get the phone working, but it was complicated and messy. Here's more or less what I did: I was able to successfully run the RUU that updates HBOOT to 1.02 (or 1.07, either one works), which allowed me to unlock the bootloader via HTCdev. (see one of the root / s-off guides if this doesn't make sense.) This made it possible to flash ClockworkMod recovery using fastboot, and boot into recovery. From there, I was able to get to a root shell through adb (plugged into my computer) and proceeded to downgrade and get s-off, following the guide. It now works, though it's running Froyo and there is hardly any space for apps due to the messed up storage. I've been wanting to try this hack on it but I haven't gotten around to it yet.

stuck in boot loop, keys dead
I have an HTC incredible. One day the power button decided to quit working. Everything else worked fine, except when the phone went to sleep, the only way to wake it up was to plug in the charger. That was all fine and dandy til I was using it one night to listen to TuneIn and forgot to shut it off. When I plugged in the charger the next morning, it went into boot loop. I can get it out of boot loop by holding the power and/or volume down buttons, but when the hboot (?) screen comes up, I am helpless to do anything, as the power and volume buttons are unresponsive. It is not recognized when I plug it into my laptop, either. For whatever it's worth, it does say "S-on" on the hboot screen, if that helps. Is it junk or fixable?

Sounds hosed to me. You could try to flash an RUU zip but that'd require use of the keys in HBOOT. If there is an RUU option that does not involve touching the phone, it's possible. Otherwise, no. I guess you could open the phone and check the button connections are there but it may be locking up at the HBOOT screen. Give it a chance to charge up a bit. However, I believe this phone is a lost cause. I seem to be seeing more frequent bootloop phone reports lately.
