[Q] What keys to boot into CWM

I am having a hard time booting into CWM, what is the right key combination? If I hold volume down and power, the Samsung sign comes on, and then the screen goes black and the phone vibrates every few seconds. I'm able to get into CWM just fine in ROM manager reboot and also with Juggernauts reboot, but it could become necessary to do it manually at some point. Thanks.

CWM boot
Need to hold volume up &down plus power keys when U see Samsung sing let power go holding up&down key till U see CWM

Working perfect, thank you!

ROM Manager Hard Bricked My Phone?

I wanted to update my phone from CM9.1 to CM10 and wanted to back it up first. The first backup never went past "clearing space..." so I cleaned out all of my old ROMs and a couple of backups. Then I thought, maybe I don't have the latest version of recovery, so I reflashed Touch recovery. Then I hit the "reboot into recovery" in ROM manager. The phone vibrated and "Samsung" boot animation appeared very briefly....then nothing. I tried pulling the battery and then holding going directly into recovery with the volume buttons and power and it would just vibrate and show the opening samsung boot screen. After trying that a few times, now all I get is the vibration.
Today I tried the "soft brick" solution, but all it does is vibrate every alf second.
So am I bricked?

Your are soft bricked.
Take battery out for ten seconds
Insert back in hold volume keys press power
Let go while continuing holding volume key. Some people hold volume keys and power continuously but that doesn't always gets it.... g luck

To enter recovery, your timing during the phone vibration has to be somewhat perfectly timed.
Power up and keep one finger in the middle of the volume control so both volume controls are pressed simultaneously with one finger on the power button. When the phone vibrates one time, remove finger holding the power button while still holding the volume buttons until recovery appears.
Good luck OP.

When I do this, all I get is a black screen after the initial Samsung boot screen. Am I supposed to follow the instructions on the soft brick thread? Or just do this over and over until something else happens?

Good news guys. I used the soft brick instructions and loaded recovery through odin and it booted up into CM9 on its own! Thanks for the help!

Have you tried holding volume up and down at same time while holding in power button at the same time plugging in the power cord this will get you to download mode so you can use odin to flash new rom if possible. Or just turn power on while holding down volume button while it powers up this will get you to download mode without the power cord also.

No bootloader no recovery. Stuck on htc quietly brilliant screen

I was flashing a new rom yesterday. But during flashing, the recovery 'hang'ed. I pressed the power button for a few seconds, it restarts to the htc quietly brilliant screen. Now I can't access bootloader or recovery using Power + Vol buttons. Please help

Turn off the phone completely press power button for about 10-15 sec then try with 1. volume down and then press power button no way to not go in bootloader. The hangs on the recovery can't broke your phone.

Still can't go to bootloader. I tried different ways. Press the power button then the vol down button. Press them at the same time. Vol down first then power button. Still stuck on the same screen even after I pressed it for minutes

After half an hour, now I can go into bootloader! What to do next ?
Edit: I flashed a new recovery. Flashed a new rom. Now all is back to normal. Thanks for your help.:good:

I was excited to wait a new ROM since in a couple of days ago, when I turn on my phone the HTC white screen is stuck when I attempted to install the new ROM (4.2.2). Even pressing the power button, volume buttons and bottom slides won't work.
Is there a chance to repair my phone?

M8 brick after OTA? No Bootloader/fastboot!

Hi,
I was on open bootloader, S-On, TWRP and root. For the Stage fright update 4.19.161.13 (Vodafone) i reinstalled stock recovery and applied the OTA. It rebooted twice and gut stuck at One logo for an hour, so i shut it down by pressing Power + volume up. Now it doesn't boot. When i press Powe + Volume up then the One logo appears for a few seconds and then i get a black screen, but when i plug the one into my pc, the pc says mtp-device. Unfortunately i cant get into the Bootloader or Fastboot. Does anyone has advice for me? Thanks in advance.

Hold power and volume up and when the screen goes black you switch the volume to down. Keep the power button pressed at all times and hold these combos until you see the bootloader. Works flawlessly......if it doesn't it's your timing that's off

I'm on vodafone too and had the same problem.
Just follow MrHofs advise to get the screen back.
I have to restore from TWRP to get the phone running.
the update still comes up on my phone now but I'm not going to apply it until I now kow.

Thanks, it worked. The screen wasn't actually black, but on and just really dark gray. In a dark room I could see when it's reaaly off and the press Power + Volume down.

Try this....

Can you help me? My phone is restarting again and again , Even it doesn't stay in Bootloader for more than 2seconds i can even go to fastboot to fix my phone , I am Locked Fully Stock

Help with brick?

Hi I was running the Cyanogen Mod Nightly for my phone, and hadn't updated it for about a week. When I went in to my settings to update it, I downloaded the latest one and when it was done it prompted me to start it, so I did. It got to about 2%, and after that it's been looping in boot. The screen flashes on and off instantly every 5 seconds. Power + Volume Up works, it shows the HTC screen and says it's going into recovery, but then it just loops in boot again.
Is there any fix/hope for my phone?

Press power + vol up, and as soon as the screen goes black, press and hold power + vol down. You will boot into the bootloader. from here you can flash an RUU to go back to stock

So I tried doing this, but nothing happened.
I did however, fix my problem, by holding down Power + Volume Up until it showed the initial "Booting into recovery" screen (which was failing), but kept holding Power + Volume Up until the Battery Charging screen showed up (I had it plugged into my PC). Once I let go, it rebooted the phone normally, and started up Cyanogenmod. Now the phone works, so I am going to back up my data, and switch to a non-nightlies version (or just never update).
Thank you!

Next time if you are in a bootloop, just holding vol down during the next restart cycle will get you to bootloader.
If the buttom combo (Power+vol up to force a restart, then just hold vol down to go to bootloader) doesn't work, its virtually always due to getting the timing wrong (either not pressing vol down soon enough, or letting go too early). And the fact it was looping makes the timing tricky. But holding vol down during a bootloop (restart) will always get you to bootloader.

I already tried that, it would automatically go back into a bootloop. And I tried your second option, which also didnt work. The only way I personally was able to fix it was having it plugged in, holding Volume Up + Power through the bootloader screen (which would crash) until the battery icon with the red disclaimer text showed up. Then it would reboot without going to bootloader (Pretty sure the Cyanogenmod tried to get it to this and failed).
Still cant get it to update without crashing so im just going to flash a new rom.
