[Q] Can't boot into recovery! Has the method changed?

Just rooted my moms evo and tried to boot into recovery holding vol down and then the power button. Was able to boot into it using quick boot so i downloaded a rom, it got stuck on the HTC screen and now we cant get into the recovery. Has the method changed?

Okay, i decided to try something on my wife's evo. I disabled fastboot in the settings and tried to boot into recovery. I went straight to it. Is there something about fastboot that wont allow you to boot into recovery? My moms on the road and I'm trying to get her to recovery to do a restore.

Yes, if you have fastboot enabled, it will NOT boot into recovery; you need to disabled fastboot first.

The thing is, her phone is stuck on the white HTC screen and wont boot up at all. Is there anyway to get into the phone to disable fastboot? Any help would be appreciated.

[Q] How do I get SU back? I broke it...

After flashing a JB rom and a corresponding JB Super SU zip this morning, I accidentally uninstalled the Super SU thinking I had a different SU app already. Turns out I didn't, and now I don't know how to get it back. I flashed the SU zip again in recovery, didn't work. But now nothing requiring root access works, so I can't even get back into recovery as far as I can tell. What do I do to get root back?
UPDATE: No matter what kind of weird things you may have done to your GNex, if you happened to have screwed up your SU abilities somehow, these next few posts will most likely help to guide you. I screwed mine all up to hell, and these guys helped me remember what was going on and what to do to fix it.

Reflash the ROM.
Try getting into fastboot, through the volume and power keys when the device is shutdown.
Happened to me before, that was the only solution.

you can download the superuser app from the market

Duh. That was easily the dumbest thing I've done this week. Funny the things we forget to be easy if we hardly ever do them.

I DID IT AGAIN!!
I didn't learn my lesson, and kept screwing around with the super user apps, and I ended up removing the super user binary. (what is wrong with me?) So this is a little more serious... Now what do I do?
I'm not a noob rooter (rooted my OG Droid 2 years ago and kept up with development, now the same with my GNex) but I guess I somehow got around having to deal with SU issues the whole time.

Do you have CWM installed? If so, just flash this in recovery.

That's all I use, but I can't get to recovery. I'm running stock JB rom, so there's no option to reboot into recovery from the power menu, and since I don't have super user, no app can get the permission to reboot into recovery either. I can power down and boot into the bootloader (or whatever that is) holding the volume down and power buttons, but I don't see how that helps.

power off the phone
hold volume UP and DOWN and POWER buttons all at the same time

from there you can scroll up and down using the volume buttons and select an option using the power button
select recovery press the power button this will get you into recovery

if you can get to the bootloader, scroll using the volume keys to get to 'recovery mode' and select that. that is recovery and you should hopefully have CWM or TWRP still installed.
bah... blowtorch is faster

Once your at the bootloader, you should have the choice to boot from there into recovery, though it's been a while since I've done it that way so cannot give you the exact steps. You should be able to use the volume keys to highlight the recovery option and then press the power button to choose it, I believe.
But you may have lost CWM, since JB could have over-written it. If so, you'll need to use fastboot to re-install it, after which you can use CWM to apply an SU zip from your internal SD card.

Thank you blowtorch, Zepius, and high vista! It was having both vol buttons pressed that I had completely forgotten about. That solves the problem and dams up a flood of questions that could have been had I not gotten that minor detail in.

[Q][Done] How to boot in Recovery (without vol' button and stuck on boot...)

Hi
I think my case is lost and is going to be "go guarantee" but I prefer to ask in case I miss something.
I've got a DHD with volume buttons (down+up) not working, and I flashed a rom this morning and now I'm stuck on boot.
Sometimes it happens and a reboot with pulling out/in battery works nice but here, it doesn't.
So here, is there a way to boot in recovery/fastboot mode when the phone is turned off or booting ?

Try to see if you can find it with adb while booting.

I can see it with adb!
Yeah, I suppose I can reboot it in recovery mode via adb reboot recovery.
(it worked!)
Well, I'm gonna put something on my sd to flash again.
Thx

Glad you got it working

hboot / bootloader <-- cant get there

Just got my s2 a couple days ago. went ahead and rooted it, threw on a Jedi Knight. I wound up switching recoveries to twrp as well. i like to flash roms alot till i find what i like best (dont we all). I wanted to try pa 2.52 but was unable to get it to bootup so I restored Jedi Knight.. I hit up the pa thread and people mentioned formatting internal storage. So I did that, and managed to get pa 2.52 on without any problems.. In the reboot options bootloader is not there.. So I started with my battery pull options to get there and nothing seems to be working..
some battery pull scenarios:
volume + & power = 1 vibe, samsung logo, let go >> boot back to rom. If I hold past 1 vibe, more continous vibes and no boot up at all
volume - & power = same as above
volume +- & power = 1vibe, samsung logo, let go >> recovery. If i continue to hold past the logo and then let go >> boot back to rom.
I'm trying to get to hboot just so I can see my s-off status & radio versions.. Much thanks..

Boot loader and s-off are for HTC phones not Samsung phones

I can see someone is coming from an HTC phone haha... If you are on the the T989 booting in download is volume down+volume up + power, or recovery mode its volume down + power.

That would be why I am familiar with them.. I left my incredible and got the s2. Is their anything similar to that for us or no? Not that it makes a difference..

Wait...so there is not bootloader
Hello I was attempting to get into my bootloader and I can't. If I am in the phone and press the power button I get the option to reboot if I click that I have the option to reboot into recovery, reboot into bootloader, or just reboot. Why have the option to reboot into bootloader if there isn't one?
I thought I booted into the bootloader to factory rest my SGH-T989 when I purchased it from someone was that not the case? was I booting into some sort of recovery?

Yes, you booted into Download mode which is the mode needed to flash your phone over usb with a tool called odin. In most cases it doesn't wipe the /data or /emmc partitions though so the best thing to do is to use the factory restore in android or your installed recovery.

[Q] HELP - Stuck in Boot, unable to Flash back

First, I'll admit I made a mistake. I installed the wrong version of Gapps when I install CM10 and therefore the phone wouldn't boot to setup. However, when I attempted to get back to stock to recover, the phone now gets stuck at the 4th boot screen with the pulsating Samsung. I can only get to Download mode, but I can't seem to get back to CWM Recovery. I have tried reflashing CWM Recovery with Odin, but I still can't get anywhere but to Download mode.
Any help would be greatly appreciated.

If you are stuck and can't get into recovery than you'll have to Odin back to stock there are stickies in these forums on how to do that.
If you can get into recovery and you are just not using the right button combo (vol up + power + home button) than flashing the proper gapps and wiping cache and davlik should fix the issue.

I have attempted to flash back to stock, and Odin reports that it was successful, but it still returns to the same point in the boot sequence and hangs.
When I use Power + Home + Volume Up, I get to the precursor screen for the Download Mode, not CWM Recovery Mode.
Any suggestions as to another way to force my way into recovery mode? I assumed that would be my way out, but I can't seem to get there.

Thank you. I must've been reading what I expected every time I saw that. Now I'm back into CWM Recovery, hopefully I can get this back on its feet.
