[Resolved] [Q] Asus Zenfone 5 stuck at boot screen (soft brick maybe) - General Questions and Answers

Hey guys...
My Zenfone 5 won't boot up. It just stops at the android screen and doesn't go any further.
I can't remove the battery as i don't have the proper tools.
how it got bricked:
I powered off my phone by pressing power button and shutdown, it was connected to my pc at the moment. i didnt wait for the charging symbol(the green battery with a lightning symbol in center) to show up, but i tried to boot into bootloader before the charging symbol showed. when i got the android screen i didnt let go the power button, so my device switched off again. once more i tried into bootloader, i didnt let go the power button, again switched off. now i hold both power and volume up to go into bootloader, and i let go power button, but it is stuck at the same screen and wont go any further.
i tried adb reboot but adb doesnt recognize my device.
Please help.
Device runs android 4.4.2 and is rooted.

Never mind...
I got it working after i hold the power button for 8 seconds and then rebooting again.
A good bit of advice: don't be hasty when ur modifying your phone. I should have thought twice before starting this thread.

The asus bootloader is already unlocked, to the best of my knowledge. (when i tried power button+ volume up while switched off, and released ONLY the power button when the "in search of incredible" screen showd up, i got into the stock bootloader direclty, which should be droidboot.)

How to shut down a (semi)bricked Xoom

I have had a hard day trying to recover my Xoom. No success. My biggest problem for now is:
How do I shut it down. The screen is on showing the M bootlogo. The powerbutton doesn't do it. From what I understand so are the tablet "off" because the charging light goes on when I connect the charger. I read in a thread somewhere that the light doesn't go on if the tablet is on.
So how do I shut down a tablet that's not on?
I'm afraid that the screen will be damaged if it has the same picture on it untill the battery is drained. Perhaps that's not the case nowadays, but I don't know.
Anyone that do know?
Have u tried just hold power volume up?

Yes. That only reboots to logoscreen and Starting RSDmode 3.

Can't just shut it down. Gotta boot into fastboot and flash a boot.img, then power it off. Obnoxious I know.

Hold volume up and power at the same time. See if that works!
Oops just saw the 2nd post.
Yup, follow post #2 to shut it down. But make sure you let go of both buttons as soon as the screen turns off. Also, if you wanna unbrick your semi bricked xoom, use a windows XP machine (win 7 64bit just gives me too many problems). You can use the one click root solution to make it easier for you. To get it to fastboot mode (to restore the boot.I mg and system.I mg files), you have to hold power+volume up button, and as soon as the screen turns on, let go of both buttons and press volume down immediately.

u may need to download your devices partition images and reflash them in fastboot
Thank you. I'm sorry but that didn't help. I can't boot into fastboot mode. When I follow your advice I boot into the logo screen without any text in the upper left corner. Then I give the "fastboot flash boot boot.img"-command from CMD. It just sits there <waiting for device>. I think I have to send it back to Best Buy and let them repair it. It was nice for 5 hours though. My personal best in bricking.
I got stuck at that screen once and shut it down by holding the power button for a very long time. At least 30 second, if not more. Perhaps that'll work for you.

OK, try this.. Reboot the device by pressing on the power and volume up key. Hold both keys til it reboots and you see the motorola logo. As soon as you see the motorola logo, let go of the power and volume up key. Press on the volume down button once and it would then give you the choice of booting Android (recovery), press the volume down again for the RSD mode, press on the volume again and it will then give you the choice of fastboot mode. Pressing the volume up key will select the current boot mode displayed... See if that works..

No. I can't get into any recovery. It boot into RSD mode 3 or no text in upper left corner. In that mode I can't use fastboot or adb. What can I do with RSD mode 3? Can I create the file that can be flashed with RSD Lite from a wifi xoom dump in the development forum?

Need help w/ bootloader

ok guys heres the problem...
My bootloader is blank. ill try to get in it but the blank screen turns off and on constantly.
i cant normally boot 2.2 because im stuck at the M Splash.
i cant sbf because my bootloader is blank and my power button is jammed.
HELP
How do you access boot loader mode? If you get M screen, bootloader should be fine. The right way to access the bootloader is to hold volume up and down at the same time while phone off then press power button like you're powering on the phone.

It won't Boot and shows a lock on the screen!!

hello frnds,
i am from india (duh) ...my friend bought a galaxy nexus s two days ago..
she had it up an running and it was working as it should.. but yesterday when she woke up..what she saw was that the phone won't boot up and a it shows a lock sign on the boot screen below google and that it was heating up badly... even the pc is not detecting it..i have the phone right now and i promised her that i'll fix it...
what should i do to keep up my promise!
bootloader is locked, phone won't boot
Hello,
The lock simply means that the bootloader of the phone is currently locked (as it is from the factory).
If it won't boot past the Google screen, try removing the battery of the phone for 10 seconds, then trying again.
If this fails, remove the battery again, replace the battery, hold down the UP volume button while pressing power until you see a green android screen. If you can see this screen, then use One Click Root 5.1 in the Development Thread for Nexus S or Nexus S 4G.
hmmm..
thank for the relpy,
well i have tried all that stuff i.e removing the battery for 10 sec..(didn't work)...
wen't to recovery mode(the green android thingi...) and tried recovery option won't work..
do you mean i should flash the firmware again by using one click?
thanks in advance!!:angel:
The lock sign means that the bootloader is UNLOCKED. If you didn't see the lock it would mean that the bootloader is locked (stock). The recovery option won't work because you haven't flash any custom recovery. In fastboot mode (volume up+ power button) it should say: LOCK STATE - UNLOCKED. This means that bootloader is unlocked. Use the toolkit (found in nexus s android development) to flash stock image.
Someone tried to do stuff to the phone and messed up.
thanks
i will try this let you know.:fingers-crossed:
thanks for the help:good:
What causes this though? I have codename jb And cwm 6 on my device and it randomly gets stuck on the boot screen through out the day

To get into bootloader hold vol- while holding the power button. Don't let go until it reboots. It will now be in bootloader

You need to let go of power, but keep holding vol down. If you don't let go of power, nothing will happen (except the phone shutting off).
The most surefire way (works in just about any situation) is to hold power and volume down. Don't let go of volume down until I say so later. The capacitive buttons will flash after about 5 seconds. Then the buttons will stop flashing, the screen will turn off (if it was on). After that, release the power button, but keep holding volume down until the white bootloader screen shows up.
If the screen turns on at all, the phone will always be able to go to bootloader. Failure to get into bootloader is almost always a matter of the user not performing the button sequence properly, rather than an issue with the phone.

Phone stuck at Verizon loading screen, can't fastboot

Hi guys,
So my buddy rooted my phone for me and had me on lollipop. Somehow I connected my phone to my friends samsung fast charger and my phone updated normally, and now my phone is stuck at the verizon loading screen on my phone. I can't open the fast boot with the hard commands, (Volume down and holding power button). The only thing I can do is do the soft reboot with the volume up and power button. Any help would be greatly appreciated. I would be fine with doing a clean reset or even going back to stock I really just need my phone to be working.

When you do volume up and power you need to time it right to switch to holding vol down in order to enter boot loader. If you wait for the battery to die you can also boot into boot loader by holding vol down when you connect it to the charger and it gets enough of a charge to boot.

So whats the exact combination? You hold down power button and volume up and then switch to volume down when the screen goes black? Thanks for the help.

Yeah it does take a little practice. I've had a lot of practice at it now I seem to have that problem most often when trying to change boot animations, it will get stuck at the Verizon boot image and after about 5 minutes of waiting I end up doing this.
