[Q] Stuck on Htc Logo and can not power off

Hi Everyone;
I unlocked my phone for flashing custom rom. After unlocking i reebooted it and was normal. Then i flashed cwm via htc one toolkit. It was successfull as well. Then i go to cwm and made factory reset + wipe cache + dalvik cache. Then i go to install zip from sd card but i could not find my rom file. Thought, it was deleted while unlocking device. Then decided to reboot phone again to copy rom file into the phone and reboot.
But, when i rebooted phone from cwm, it stuck on HTC Logo( Quietly Brilliant screen). Waited sometime, but nothing happened. Then i tried to power off it and boot into bootloader or recovery. I press and hold power button but it does not respond anyhow. When i am holding power button ,back and home buttons are blinking but nothing happens. Almost five minutes i waited as holding down power button but phone does not power off anyhow. i tried all methods like vol down + power, vol up + power and both volume keys + power. But really nothing happens, just blinking back and home buttons. That's all.
I can not simply power off device. :crying:
I also tried boot device via fastboot commands but it says "waiting for device" means computer does not recognize device.
Guys, i need an urgent help. Please...

just keep trying to reboot via holding power or power+vol down. if it doesnt reboot after 30 sec or so let go then try again. if that doesnt work you will have to wait for the battery to die. once you get to bootloader use all in one toolkit to erace cache. then boot to recovery and you rom should be there if not boot back to bootloader and sideload rom

First thank you for your quick reply. Unfortunatelly, power+vol down does not work at all. Maybe i tried 50 times.
Anyhow, after battery die. How can i boot into bootloader. I mean, can phone be charged again in this situation? Also, even if i manage to boot into bootloader or recovery how can i put custom rom file into phone. Actually, i did not use sideload or whatever you mentioned before.
I am serouisly confused now and don't know what to do.
Anyhow, as you said, firlst i need wait to battery die i think. Then i will report back whats happen.
Thank you again btw.

yes your not the first person with this problem. hold power+vol down to get into bootloader. press power button in bootloader to get in fast boot mode. use all in one toolkit to erase cache and side load rom. i recommend all in one toolkit because it automates the process. just select the option then follow on screen steps

Good to hear that i am not the first person That means somehow there is a solution i beleive. Still waiting for battery die. even i had 50 percent battery at the begining but still it holds on I never say again htc battery is bad
I exeprienced that stucking on boot logo several times before with my other htc phones but holding power + vol down/up worked always. This is the first time for me that i faced with power button can not power off device.. Well, ,i hope i wish i can handle out this problem. Definetley with your help.
Regards,

I am having the same problem and don't know what to do :crying:
Today I just got my One. Unlocked bootloader, rooted, flashed Android Revolution rom. Everything worked fine for a while... I wanted to reinstall the rom because I wanted to change some options in the installer - I did not wipe because it was the same rom (big mistake I guess!!). After making the installation option changes, when it was done it proceeded to reboot but now I am stuck in a white HTC logo boot loop hell... (with the red text at the bottom that says "this build is for development purposes only" etc). Holy crap I never had a phone that I could not remove the battery. I cannot get this back into recovery or ANYTHING, it just keeps looping... computer recognizes it, no problem with drivers or anything it just doesn't stay connected long enough (because of the constant looping) to be able to use the toolkit.
PLEASE any advice?? Can't even shut it down omg. Do I have a $600 brick here? :crying::crying:

Did you read the other posts in this thread? The way you do a "battery pull" on this phone is to HOLD the PWR + VOL DOWN button for ~15seconds. Your capactivie buttons will blink, too. On my device, it took exactly 15seconds to reboot. There have been some reports of some phones that get so stuck that you just have to wait until the battery dies and charge it back up.
Alternatively, if the computer is recongizing it, try to adb reboot recovery to try and get into the recovery.

hi again. this morning my battery finally out. Then i put my phone to the charger and started it in fastboot mode( that is a good new) Then i left it for 20-30 minutes to charge a little bit for flashing custom rom.Then i went to recovery and started adb sideload. Sideload was succesful and finally came to aroma installer of trickdroid. I chose my installation options and started to flash rom but process was frozen on 10 percent. It was saying unmount system, unmount cahce and both of them has notification as "already unmounted". But installation was not going on. Then again i tried to go back fasboot mode again by press and holding power+vol down but unfortunatelly lights are blinking but nothing happens again. I think i need to wait to battery die again.
Isn't it quite weird? Why power+vol down combination does not work for me anytime? So, do i need to wait for battery die in every frozen? Do you have any ideas or comments ?
Do i need to go back to stock first ?
EDIT : Battery was out again and i tried once more. This time installation (trick droid) was successful but it frozen at the end this time. And unfortunatelly i can not restart (power+vol down) it again again Holy crap, i am really pissed off with this problem.

O..K...Finally, i managed to start my phone and now it works... Especially thank you skinsfanbdh for your support.
But still i don't know how to solve button configuration problem. But anyhow i think i won't need quite sometim to use it I hope someone can find a solution for that later.

Guide me with steps please

hi itried to install twrp through sp flash tool but instead of using mt6589 scatter.txt i used mt65xx scatter.txt now my phone is stuck on rebooting plz help

Alright guys... Try hard reset... What you must do is get your phone to off... Once it's off properly wait for about 40-45 seconds and then press the power button and both the vol buttons simultaneously... Then there will be an option for vol up-go to recovery & vol down-go for factory reset

it happened to my A250 too. i tried all the above method yet no result...still stuck at boot loop. plz help .

Help! Stock Moto X bootlooping suddenly

Hi people,
I hoped I would never have to ask for help with my phone, but its randomly bootlooping and I have no idea why or how to fix it.
Basically, I was updating 2 apps on google play, one app updated so I went to open it while other app was updating, and my phone froze. This was slightly strange as it doesn't happen often, but google play always makes my phone lag when updating apps so it wasn't completely unexpected. So held down power button to restart it, then made that final app update again, locked it and left it. 10 minutes later I went to unlock my phone but found it seemingly turned off and feeling extremely hot. turned it on again, and bootlooped (did the 'moto worlds' animations thing then got stuck on rippling moto logo). Absolutely no idea what could have caused it. THis is where I need your guys' help, cause I have no experience of this on a moto X. I held down power button+voldown and got a menu (no idea what its called), tried every option and nothing did anything, there was no recovery, factory and SB tools went to bootloop. pls help!
Thanks in advance!

If everything is stock with stock recovery then hold power + volume down and it should boot into fastboot mode. From there choose recovery and press the volume up. If you get into a screen with a red exclamation mark and a android guy then hold power and volume up for 2 seconds and release. This will bring up the recovery and from there choose wipe cache partition and press power button. This will wipe the cache and hopefully should fix the bootloop you are having.

this hasn't worked, it was seemingly stuck trying to wipe the cache for over 5 minutes, so I held power button to reboot it and it still bootloops.

Okay I managed to wipe cache and complete it, hasn't worked, and when I went to do it again it reboots after 10 seconds of trying to wipe it. Am I right in assuming I'll have to wipe data?

If you are still having issues....yes...you may have to try doing a factory reset. Data will be wiped.
If that doesn't help, you may have to flash stock firmware fresh. If you can get your current version files.
Don't downgrade. You'll likely brick.

Yup, ended up wiping data and now its fine. Thanks to google my photos were already backed up, so I didn't lose too much. Thanks anyway guys

Nep, I can't, I can't boot into download mode, and i can't do wipe
It's so complicated for me

That's weird. I assume the power button seems to be faulty. Were you running a stock rom? Did that happen out of the blue?

so im here needing ur help
thank you

What if you pull out battery for some minutes and then try to start your phone? Doesn't work either?
And my other questions? What did you do before that boot loop happened? Are you running stock ROM and stock recovery?
Btw you don't have to quote each post, it is easier for reading

I give you a summary of the situation
I have a 9305 Black edition SIII, it restarts in a loop, and I can not charge the battery gets stuck with low battery and reboute yet, I even tried a different battery type EB-L1G6LLU and it lasts for two week almost;
The download mode does not work, every time I enabled it restarts,
The recovery mode to wipe the same, it does not even appear,
I tried to connect via keis Odin and the other failure of the operation
I even tried to change the connector, the same thing
Frankly I do not know what to do, If you have a tip, hint is welcome

What did you do before that boot loop happened? Are you running stock ROM and stock recovery? or all custom? If you pull out battery and put it back in, does the phone start on its own without you pressing the power button?

I tried any solution possible in Internet and form from the world wide.
My motherboard are dead so, I have only one solution it's to buy a other.
Thank you to be here and answing

Bricked Huawei P9

Hello,
after a couple of attempts at installing TWRP recovery, some successful, some not, a ROM reinstall and finally this last factory reset, my Huawei P9 phone is stuck at what appears to be boot or restart loop. It is interesting however that I am unable to turn off the phone at all and it's been like this for an hour. At first, TWRP recovery wouldn't boot but the OS would. Then I did factory reset and phone restarted. Since then it won't boot or turn off. When I hold the power button to turn it off, it vibrates once, then vibrates again and then Huawei logo is displayed. After that a message that says "Your device has been unlocked and can't be trusted." & "Your device is booting now..." which is normal since I unlocked my phone bootloader, but the problem is that it is just stuck there.
It stays there forever, screen on, phone on, can't restart because it comes back to the same point, can't turn it off since battery is impossible to take out... Any hope? I bought the phone a couple of days ago and this is really bad... Help!
Edit: In case someone else stumbles upon similar situation - after trying everything possible with these 3 buttons I had available (vol+- and power), I have managed to boot by (I THINK) holding the power button for 10 secs but releasing it really fast after the screen turns off and BEFORE the first vibration happens.
Edit 2: Now I have the same problem again and I can't seem to get the right button "combo" to pass the booting phase like I did some hour ago... Any ideas?
Edit 3: It appears that the ROM I have flashed caused problems with TWRP - after I got an SD card, managed to put stock ROM (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) on it and then did force upgrade, the phone booted successfully.
Step by step:
1) Drained battery to 0% and forced phone to turn off (otherwise it would vibrate twice and get stuck loading TWRP if I tried to turn it off using power button)
2) When I plugged it in and it got some battery power it started, avoided TWRP and regularly booted the OS (which was causing problems with TWRP in my case I think). If you don't have any OS, do not recharge or turn on your phone until you have prepared and put SD card into the phone
3) Downloaded and extracted the dload folder from the P9 stock ROM archive (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) to root directory of SD card
4) Unplugged and turned off the phone using OS Shutdown option
5) Turned it on by holding power, volup and voldown buttons together - "Your device has been unlocked and can't be trusted. Your device is booting now..." message appeared so I thought it was stuck again and was about to hang myself, but then the OS upgrade started (if it doesn't work right away, try restarting the phone with power, volup and voldown buttons held together again)
6) Upgrade was successful but the phone wouldn't boot without complete factory reset, after which it booted normally. Bootloader was relocked, then I updated to the latest stable EMUI (4.1.1) and life returned to normal.

BUMP
I can access Fastboot&Rescue mode and use abd (but phone is not rooted). Other than that I can't get to repeat what I did when I managed to boot the phone previous time this happened some hours ago... Can anyone post all volume+- and power key combinations which I can try?
Any other ideas more than welcome...

Guys can someone help with this. I'm having the same sort of issues. I have flashed an update and now I have lost touch on the screen. I can't even use twrp because the touch is not working.
Please can someone advise.

After getting an SD card (everything I did so far was using internal storage) and putting stock Huawei P9 ROM on it (Android 6 and EMUI 4), then shutting down (forced by draining battery) and doing force upgrade (vol+ and vol- held after power up) I have managed to (upgrade and) boot my phone and get it back to normal again. If anyone needs more detailed explanation on how I solved this, feel free to ask.

Open bootloader again, i had the same problem few days ago

Yes please vernicht. My touchscreen has stopped responding after flashing an update.app using DC Phoenix.
I really need to get the phone back to normal.

Can you boot into OS? Please provide more exact details.
How I got out of the TWRP(?) boot loop: I couldn't take out the battery, but I have managed to drain it to 0% by letting the phone stay on for hours thus eventually shutting itself down. After that I have charged it and then powered it up. It didn't attempt to boot TWRP (no loop) but instead booted back the OS. After that I could regularly restart the phone and do all operations without getting stuck in loop, which allowed me to issue force upgrade command using hardware power up/down buttons.

Nope. I manage to flash it with DC Phoenix fully but it just keeps boot looping and going back to the Huawei logo. Then after that if goes into its recovery menu and the only my to use the menus is with the volume keys.

Are you able to put files on your SD card? If yes, you can try putting stock ROM on it and then force force upgrading (hold vol+ and vol- together after power up). It should overwrite everything and boot up.

I have done this but it won't even force flash the stock rom. It gets to 5% and says 'system error'
I followed your suggestion to let the battery drain and then I charged it fully, but when charging it got to 1% and rebooted the phone into eRecovery.
I wish I could get this phone fixed and back to normal.

Did you use this stock ROM for P9 (if it's EVA-L09 like mine) or something else?
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
It worked fine with force upgrade for me, while some other ROMs didn't.
Do you have Wipe cache and data/factory reset options available in eRecovery, did you try that?

I'll try that. The only problem I have is my touchscreen won't respond under eRecovery. I have to use the volume and power key to navigate. Any idea what's happened there?

It will probably return to function after you restore to stock ROM. Until then you can use power button to select items in eRecovery if needed.
Btw I have edited my original first post in this thread with step by step guide on what I did in my case.

Thank you Vernicht for all your help.
I finally manage to get the phone fully working again. I also managed to get it changed from C900 to C432, lock the bootloader and join the beta.
Thank you so much again. It's very much appreciated.
Merry Christmas too

Hi nscxp2005
how did you manage that?
i have the same Problem.
i have done a "Wipe Cache" and a factory reset.
i have copied the "update.app" from PauloBrien zip on a sd card in a folder named dload.
then i have done a Force flash -> it goes to 5% an says Invalid File.
when i look in the device with DC Phoenix it says it is a EVA-L09C900B136
Why have i done that?
My wive have the EVA-L09C432B136 and i updatet it OTA to Nougat.
i thought i could switch to that version to get the new Nougat but something went wrong......
thanks in advance and sry for my english =)

Hi Guys, hope you can help
I have got an P9 EVA-L09 which I tried to update to B378 but failed and now it stuck in a boot loop and won't recover using the phone.
I have tried to download the update mentioned above and doing a forced recovery on the phone Power + VOL+ + VOL- but no luck, gets 5% and fails.
Would like some help please.

Hello, I have the same problem, I tried to install Lineage 14.1 and it didn't work. Then i tried to go back to EMUI 5.0 and i just all fell apart. No i have no android on my P9 (cos i wiped all data and the system through TWRP 3.1.1.1), and now my touchscreen doesn't work. When i try to force install, it blockes on 5%. Anyone have any idea on how to fix it? Thanks

Hello,
after a couple of attempts at installing TWRP recovery, some successful, some not, a ROM reinstall and finally this last factory reset, my Huawei P9 phone is stuck at what appears to be boot or restart loop. It is interesting however that I am unable to turn off the phone at all and it's been like this for an hour. At first, TWRP recovery wouldn't boot but the OS would. Then I did factory reset and phone restarted. Since then it won't boot or turn off. When I hold the power button to turn it off, it vibrates once, then vibrates again and then Huawei logo is displayed. After that a message that says "Your device has been unlocked and can't be trusted." & "Your device is booting now..." which is normal since I unlocked my phone bootloader, but the problem is that it is just stuck there.
It stays there forever, screen on, phone on, can't restart because it comes back to the same point, can't turn it off since battery is impossible to take out... Any hope? I bought the phone a couple of days ago and this is really bad... Help!
Edit: In case someone else stumbles upon similar situation - after trying everything possible with these 3 buttons I had available (vol+- and power), I have managed to boot by (I THINK) holding the power button for 10 secs but releasing it really fast after the screen turns off and BEFORE the first vibration happens.
Edit 2: Now I have the same problem again and I can't seem to get the right button "combo" to pass the booting phase like I did some hour ago... Any ideas?
Edit 3: It appears that the ROM I have flashed caused problems with TWRP - after I got an SD card, managed to put stock ROM (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) on it and then did force upgrade, the phone booted successfully.
Step by step:
1) Drained battery to 0% and forced phone to turn off (otherwise it would vibrate twice and get stuck loading TWRP if I tried to turn it off using power button)
2) When I plugged it in and it got some battery power it started, avoided TWRP and regularly booted the OS (which was causing problems with TWRP in my case I think). If you don't have any OS, do not recharge or turn on your phone until you have prepared and put SD card into the phone
3) Downloaded and extracted the dload folder from the P9 stock ROM archive (http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818) to root directory of SD card
4) Unplugged and turned off the phone using OS Shutdown option
5) Turned it on by holding power, volup and voldown buttons together - "Your device has been unlocked and can't be trusted. Your device is booting now..." message appeared so I thought it was stuck again and was about to hang myself, but then the OS upgrade started (if it doesn't work right away, try restarting the phone with power, volup and voldown buttons held together again)
6) Upgrade was successful but the phone wouldn't boot without complete factory reset, after which it booted normally. Bootloader was relocked, then I updated to the latest stable EMUI (4.1.1) and life returned to normal.

I have the same issue after flashing the rollback package from the official huawei site. The phone isn't rooted, it just had a branding for some odd reason. So I installed the C432B182 but somehow ended up with a C900B... firmware. So I installed the Rollback package C900B300 using the 3 button method. It said successfull but ever since I've been stuck in the same loop. At the logo. Trying to enter recovery mode (Volume Up + Power) or Force flash any of the firmwares (stock C432.. or rollback C900) doesnt succeed. It wont attempt. Only vibrates as you described and turns the screen off for a second before entering the same loop again.
How did you manage to enter the flash Menu??
Thanks in advance and hope you can help.

Hello!
At me too such problem. When charging to sit at 0% and plug it into the charger, it immediately turns on and goes into the system, then the screen is worth a long logo. I have a phone EVA-L09C627B150.
Help me find my full version! Or I can use this version by reference https://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
Sorry for my English!
