That's very unusual. Presumably you're running some sort of modification (lagfix etc.). Is this the first time you've rebooted since your last flash/modification? If so what mods are you running.
Have you tried download mode (Home + Volume Down) or just recovery mode (Home + Volume Up)?

i applied the lag fix and had jh3 rom for bell and it worked fine and then the next day the system force closed some apps and i thought there was some thing wrong and i restarted the phone and the screen comes on but its blank after the S. i tried flashing a different rom and after odin when the phone boots up it says cant mount blah blah...HELP plz

[Q] HELP ME PLEASE - stuck in Android System Recovery <2e> screen

So, I tried to put another kernel on my AT&T Captivate i9000 and it just bricked my phone. I read around for a while before I did it and thought I had the correct kernel for my captivate. For a minute I could get to the ClockworkMod Recovery menu by holding down the volume buttons and then going to download mode which is my ultimate goal.
I downloaded kernel-captivate-stock.tar.md5 which is the original kernel and I thought my Captivate would work, and boy was I wrong. I'm stuck on the Android system recovery <2e> screen with options reboot system now TRIED IT, reinstall packages TRIED IT, delete user data and delete cache data.
I have adb installed and I know how to use it but it's not recognizing my device when I'm in the correct folder and I have ALL the newest drivers. I thought it would be easier to do adb recovery download because at first it did recognize my device and now it won't, so I can't go the adb method. I turned off the device, took the battery out, the sim out and held down the volume keys plugged in the usb and I'm back to square one.
I also have Odin3 and also Odin One-Click Downloader downloaded. As for Odin3, I have the .pit file, the file for the PDA section, the PHONE, and the CSC section. I've looked at every single thing on the Internet today and I can't get my phone back into the download mode so I can flash it, it's stuck.
When I click reinstall packages I get the following error
"E: Error in /sdcard/update.zip
(Status 7)
Installation aborted.
E: Can't mount /dev/block/st111
(Invalid argument)
E: Can't mount /dev/block/st111
(Invalid argument).
I'm stuck on that screen and no matter how many times I hold down the vol. keys or do any combination, I'm still stuck there when the phones starts back up. Sorry for the long story but please help. I trust this community. help !!

Have you tried:
Pull USB cable.
Open JF6 ODEN install I897UCJF6-final-OCD-REV0
Pull Battery
Put usb in
While holding both volume up/down insert battery
It should go into download.
Start Oden and the after reboot
Pull usb
select USB development
Reconnect usb
Master clear.
-- It has worked for me.
Hold Volume Down, Home, and Power on. Turn on odin(or heimdall), plug usb in phone, and then in computer. Correct order or you get spanked.
Also, if you download DG's stock odin package it only works once for me, after that i have to re-download it.
FTR: use Neldar's kernel flashing app, it works wonders.
Also, if you use odin and it fails you have to close odin, then re-open it. Same for Download mode, you can't flash 2 packages. Just use DG's One-Click, you have corrupted /data or /dbdata, whichever contains block st111.

If taking the battery out and then plugging in the USB cable and holding both volume buttons while inserting the battery doesn't work then you may need a jig. And in the future use the proper stock firmware so as not to disable your button combos (and use it sparingly, since flashing to stock is almost never necessary).

Sorry, I don't quite understand. Are you saying that once you're on the screen, you can scroll through the options but can't select anything with the power button? Or that selecting something just reboots your phone back into the recovery menu?

Are you sure power is working? I can't tell what you are saying, but it sounds like either the phone is freezing after you select something or the power button isn't working, preventing you from doing anything with the menu. The latter is a known issue with some kernels.

[Q] P880 hangs at boot | No S/W update available

Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

failed to mount preload (no such file or directory)

I was trying to root my phone and get a message that says 'kernel is not seandroid enforcing'. Not knowing how to fix that I decided to do a factory reset and upon reboot get the error 'failed to mount preload (no such file or directory). I have a galaxy note 5 for T Mobile. The phone isn't unlocked. Can anyone help?
Anyone have any ideas?

Turn on the phone, and when you see kernel is not seandroid enforcing press and hold Volume Up, Home, and Power button at the same time until you see a warning. Then press Volume Down to cancel. Now wait for it to reboot, it should boot up normally.
I tried that, but it takes me back to the same screen that I was getting the original error

Update it via Smart Switch.
This worked for me
So I tried all this. This finally worked.
What I did was from power off, help up volume, home button and power button at the same time. Then I pressed wipe cashe and then factory reset and went down to yes. Then I turned the phone off even after it failed and got the continuos error. Then I turned the phone off. Then I pulled the battery and waited approximentally 1 minute. Then I put the battery back in and put the back cover on it. After that, I help the up volume and power button only (NOT THE HOME BUTTON THIS TIME!). Then I waited approximentally 3 minutes for the logo to just flash samsung over and over again and then BAM!!! It worked.

Question MI 11 hardbricked?

Hi my phone I believe is hardbricked. It started by powering off itself suddenly, then power button become unresponsive.
Only very rarely sometimes the power button can get it to boot logo, then I can get it to TWRP recovery.
But it just off itself randomly also.
I get /system_root /vendor failed to mount (invalid argument). The OS not installed too. Now it seems like the phone is not responding to my power button holds. (hoping to get it to boot again). Anything I can do to solve this?
For info: Was using custom ROM, but now it's wiped so doesn't matter now. Was able to boot to TWRP recovery whenever it can boot. But turns off after awhile.
Not sure if this is software error or battery issue?
Have you ever tried connecting it to a PC, seeing what it shows up as?

The first few times it booted to recovery, was showing as recovery using adb devices command.
After I wiped data, cache, and formatted file system (it was a tip from online), I didn't get the chance to plug into a PC anymore because it rarely booted up now.
Now my suspicions for faults are charging port. power button or battery. Not sure if its software issue.
