When it vibrates as before - quickly release the power button only

I wonder is the OP referring to the changed sequence after the Jelly Bean update?
I have a different 'fastboot not working' problem - many of us have bricked phones saying 'service required, code corrupt'. Everyone with this brick seems to be saying they cannot get the device in fastboot.

Had the same problem, all I had typo do was wait for the screen to flicker and then I let go of both buttons. That'll take you straight to fast boot mode

Galaxy ace boot issue

OK guys, long story short my mates galaxy ace won't boot up, randomly turned off one day and booted to recovery, power button doesn't work so can't select reboot, my theory is power button is stuck in? It also has a message about csc error which is new to me.
If I flash stock rom through odin, it should reboot automatically right? However can I change the startup button because if the phone turns off it won't boot again unless I flash again through Odin which is a pain. Any help is appreciated, thanks in advanced guys

if u still have your warranty, you can get it to a service center... they would fix the power button..
My friend bought the phone off a private seller so no such warranty :/ thanks for the reply however

[Q] Help! Soft brick on SGH- i957 LTE

I bricked my tablet after I tried to change my font using font installer by jrummy?
It asked me to restart for changes to occur so I figured if I restarted on my own it would work the same way so I hit cancel. I restarted about 1 minute after I hit cancel.
My tablet will boot up to the AT&T "Rethink possible" screen (after the animation).
It will get stuck there with a pattern of light vibrations between a couple seconds each.
Currently running the stock AT&T ics rom posted in the android dev section for i957.
I've tried to boot into recovery but the Samsung screen doesn't come up until I let go of the buttons therefore leading it to reboot again.
Also tried to go into the emergency download mode ( power, up, down) but it didn't work either.
I appreciate all and any advice, please and thank you!
My device is rooted if that wasn't already implied, I will provide any other details if needed, please help!!
Thanks again!
Are you sure you can't get into recovery mode? Hold power and volume up buttons, etc. Does Odin recognize the device?
Do you have a custom recovery, and if so which one, or is it stock.

keep trying to get into download mode or recovery. should be possible. the font change will not affect recovery.
I was also performing a backup with titanium backup when I restarted does that make a difference?
I have clockwork mod recovery.
From experience, I can only go into recovery if the Samsung logo pops up for a milli second and I let go.
I actually haven't tried to see if Odin recognizes my device but I assumed if I couldn't go into download mode it wouldn't.

Were you restoring apps from a honeycomb Rom? That will cause a soft brick.
Sent from my SAMSUNG-SGH-I727 using xda premium
If you can get into recovery do a factory reset. That should get you out of a soft brick. You'll have to re-install your apps though.

I never use tibu anymore

Didnt see if you worked your way out of this or not. You may have to hold 3 finger salute (power, up, down) for up to 16 seconds. My guess is that covers the 8 seconds to reboot through any hang up plus up to 8 more to boot to menu.
Still no luck, the computer is not detecting my tablet.
I also wasn't restoring, I was just backing up my data. I'm letting it charge for now, anyone know what else I should do?
I really can't enter recovery OR download.
**** UPDATE****
Okay guys I finally fixed it. Will post details if anyone is still interested.
I'd be interested in the details.

How did you do?

I couldn't go into download mode until I did some weird trick with the buttons.
I had to hold the 3 buttons ( power, vol up, vol down) for a couple seconds.. like 6 seconds
THEN hold power and vol up for 2 secs
THEN back to power, vol up, vol down.
I did it by accident cuz I was frustrated but it ended up working so all is good
Thanks for all the help guys!!
I am in the Same Boat!

Stuck in fastboot!

After using the lg update tool to update to ics,then rooting the phone it became stuck in fastboot no matter what I've tried googled etc...it will never shut off,just reboots with silver lg,don't get me wrong it looks better than the stock lg logo but its getting a bit annoying
Sent from my LG-P925 using xda premium
Did you try to boot in to recovery then factory reset? To get to recovery press volume down + power button. That grey logo is also the new image for the boot loader you may have installed.

Yes, still stuck

Did you make a back up after rooting? If not you may have to start over. Flash v30b again. Which recovery did you use. U needed to use the ICS boot loader and the GB recovery. ICS recovey is for su760 port.

Mine is the same way. I just hold down the power button till it shuts off.

[Q] I think I bricked my phone :( :( - PLEASE help!

Hi,
I tried the regular fastboot method to load CWM recovery.
Whenever it got to the point of loading the recovering, it would just say "flashing recovery on the device...".
Then, when restarting bootloader and clicking on "recovery", it would just shut down the phone.
I decided to experiment to try fix the issue, and I came across this post:
http://forum.xda-developers.com/showthread.php?t=1928551
I downloaded the ZIP file and I ran the root.bat
It flashed some boot images and now my phone wont start
It is stuck on the "warning bootloader unlocked screen" and will not go any further.
Please help . I'm so scared that I've bricked my phone. Is there ANYTHING I can do?
Thanks in advance for the help!
The methods u used can't brick your phone
Reboot in boot loader by pressing the power button and volume - button at the same time. Just at the moment the phone shuts-down/reboot release the power button. It will boot in boot loader. After this flash cwm or twrp again and with the volume down button go to recovery. Select recovery with the volume up key and u are done. Cwm/twrp is flashed and will boot in the recovery.
In recovery I would install the ROM from Omar. It will restore your system and boot.IMG so it will work. Don't forget to wipe data.
If this doesn't work flash the home made fast boot files somewhere in the development section

Thanks - I tried that. I do let go of the buttons as soon as it starts to reboot itself, but it doesn't start the bootloader - it still just shows the screen "warning bootloader unlocked". I can not get back into the bootloader
Do u reset the phone with the 4 buttons and just when it resets does your phone reboots immediately?

If I hold all 4 buttons, the screen goes blank, and the green light stays on. My PC then finds hardware called "MEDFIELD" but wont find drivers for it.
Does this help at all?

The above applies when connected with usb.
If I press all 4 buttons without USB connected, it just reboots and gets stuck on the "unlocked bootloader" message again

Just of curiosity - which button you used to select recovery - power button or vol.up button?

You should let go only of power button and hold vol.down button (at least for me)
If your PC finds hardware - can you do fastboot devices to check whether it is actually recognized properly?
And last thing - which method you used to load recovery (and were you on ICS\JB)? You were rooted and used automated methods or you unlocked bootloader and wanted to root afterwards (manually through fastboot)?

You are a GENIUS!!! A LIFE SAVER!!! I can't begin to tell you how grateful I am. BOTH of your points fixed the phone.
I could never get into recovery becuase I was pressing the power button. I could never get into fastboot becuase I was holding both the power and volume down button.
So, for anyone using a RAZR I... please note the following SIMPLE things:
1) In the bootloader menu, the power button does NOT select the option. The VOL UP button selects the option
2) To boot into BOOTLOADER : Hold both power and vol down buttons until the phone restarts, and then RELEASE the power button, while still HOLDING the volume down button! It will then load the bootloader.
Again, THANKS so so much for reviving my phone for me. I was going crazy without a phone!

I was going through everything you've faced yesterday. So yeah, glad I was of help to someone else as well)
This has never happened to me before but don't stress one bit because nothing ever permanently bad comes from this. You can forget about it being destroyed. These aren't iPhones, haha. You can get it going again pretty easy I hear. Just don't stress because there is no point and you WILL get help. Just listen to what these experienced dudes are saying and you should be back on track. Good luck!

UPDATE: Nice! Glad to see you got the help you needed and everything's back on track!
Nice that it is solved. I gave u the solution on my first post, but nice that someone els did a better job in explaining it
There is almost no possibilities to brick your device if u only flash things like the boot, system, recovery or data partition. They can he solved very easy. If u flash the other partitions like the radio u can get a problem.

You are 100% right. I just re-read your post, and noticed that you did mention those 2 points. I must've just read over them really quickly and didn't pay attention to the details of which buttons to press. :angel:
Thanks a ton for your help! Really appreciate it! :highfive:

[Q] Stock phone bricked from OTA?

I got my wife a Moto X yesterday, which has not been rooted or modified at all, and got the 4.4 update notification today. I downloaded the update and tried to install it. During the install, the phone tried to reboot but it got stuck at the Motorola logo. It sat there for over an hour, so I turned the phone off. As soon as the phone turns off, it turns itself back on and gets stuck at the Motorola logo. I can get the phone into recovery mode, but selecting Recovery and Factory options do nothing but go back to the Motorola logo. I have tried using the Toolkit to flash the phone, but it needs to be either in Android or the bootloader so I can't seem to do anything. Do I have any other options? I would prefer to fix it myself because I can't take the phone back to AT&T until Sunday and I don't want my wife (who is pregnant) to be without her phone for that long.
Did you try to just erase user data ? (You will lose person content on the phone)
Did you try to just erase cache ?
Did you try to boot only in safe mode ?

I can't do any of that because I cannot get into the OS.
Can you get into recovery or bootloader?

Go in fastboot mode. (Power up holding vol Dow key)

When you are trying to select options in fastboot are you using the volume up to select them? I've read a lot of places where people try to use the power button to select when they should be using vol up.

I have the same problem with my T-Mobile moto I received yesterday. Prompts for update, downloads and attempts to install, then opens in bootloader with 'Failed to hab check for boot: 0x56'. If i try to boot into recovery it gives the same error, 'Failed to hab check for recovery:0x56'. If I try to factory reset from the settings menu the phone powers off and does the same thing.
I read somewhere that the bootloader and recovery images need to be flashed again but I can't seem to find a working link to download them. I should add that once I use Minimal Fastboot to give the command 'fastboot erase cache' the phone will reboot properly and prompt me to download the update again. All is good as long as I dont try to update to Kit Kat. Please help, it will be greatly appreciated.
