[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.

no. if it turns on you should be ok. try holdind power+vol down to get into bootloader then try toolkit if it just stays on waiting for device press power button to get into fastboot mode from bootloader

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

Can't enter recovery mode after installing TWRP

Hello everyone,
I bought a few days ago the Honor 5C and decided to root it. So I installed the TWRP (Nemo) using "fastboot", downloaded a ZIP of SuperSU and placed at the root of the internal storage. But when I try to enter recovery mode by using "adb reboot recovery" or by pressing the Volume Up + Power buttons, the phone vibrates, displays nothing for 2-3 seconds (not even a black screen, the screen is completely off). After that the "Honor" logo is dispayed for less than a second then the screen "Your device has been unlocked and can't be trusted [...] Your device is booting now..." with no option at all.
The problem is that this screen stays forever and never displays the recovery mode screen. If I entered this mode using the physical buttons, I can just press "Power" for a few seconds and then it reboots the phone normally. But if I used "adb", each reboot makes the phone entering again the same recovery mode that doesn't work, so I use the Volume Up + Power key while the phone is connected via USB to my laptop to enter e-recovery mode, then reboot normally.
Does anyone know how to solve this problem ? I really want to root my phone but I don't know what to do for now.
Thanks by advance for your answers !

Are you on EMUI 5 (Android Nougat) ? If so, official TWRP is not compatible with version > EMUI 4.x for now.

I'm using EMUI 5.0 / Android 7.0.
So now I've installed an incompatible TWRP can I just downgrade to EMUI 4.0 / Android 5.0 then flash it again and root my phone or should I reflash the original recovery before doing that ? I've read somewhere that updating a rooted phone could brick it so even if mine has just a TWRP and want to downgrade instead of upgrading I prefer to be sure.
Thanks by advance !

you need install original recovery and extract update.app from B100 firmware, then you place it to "dload" folder in your sd card and flash using 3 buttons. you cant full brick by messing with root. only soft brick which is fixable.

Ok I'll try it. I will post again if something comes wrong.
Thanks a lot for your help

I forgot to ask about one thing : I'm owning a phone with NEM-L51 model and I don't know if I can use NEM-L22 firmware ? If I can't, where can I find the right files to downgrade this specific model ? All the firmware files I see on the web are for the NEM-L22...
EDIT : I've found the B102 firmware for NEM-L51 model (Europe + UK) can I take it for the downgrade or is the B100 specific version needed ?

Thanks for your help but this doesn't work. When I do what you say it goes again and again to the same warning screen which never disappears. This is really strange, when I see videos I find on YouTube all Honor 5C owners that just do what you say enter in recovery mode, but it's not my case... I really wonder why.
I don't know if that can help you to understand, but I'm using a french Honor 5C phone, with EMUI 5.0 / Android Nougat like I said previously, model is NEM-L51 and I did the Android Nougat update several days ago using the Honor's official update application, which is natively installed on the phone.
About the firmwares, I've tried the B102 version for the specific model I own but each time (I downloaded the update ZIP several times, the first one with two folders named '1-main' and '2-vendor', the second with just the 'dload' files) the update stops at 5 purcents and says "Software install failed! Incompatibility with current version. Please download the correct update package."
What can I do to solve this problem ?

When you do Volume Up + Power it attemps to enter recovery mode, not recovery (that's what I read), excepted if a USB cable is plugged in (which is not my case). And that still doesn't work.
However, I'm able to enter erecovery mode by turning on the phone with only the Power button, then holding "Volume Up" as written on the screen (there are 3 boot options that shows up, but only when I boot normally) and I enter erecovery mode. But I can't do anything interesting in this mode, just download the latest firmware (which fails at each attempt, even when I'm connected to a working WiFi point), shutdown or reboot the phone normally.
Shoud I show you a video of when I boot my phone in normal mode / recovery mode / erecovery mode ?

The problem is that I can't enter recovery mode, each time I try to install an OTA or full update package from the /dload folder on the SD card it fails, so I can't downgrade at all. Do you know a link that sure points to the good update package version for the Honor 5C on EMUI 5.0 in order to downgrade to Marshmallow ? I've found several links during my searches but I don't know if the installation fails because of a phone's bug or if it fails because of an invalid version.
EDIT : I forgot to precise the long model name of my phone : NEM-L51C432B350. On Firmware Finder Rewrite it shows that there are only two update packages for it, published on 20.04.2017... So I wonder if I need to download the three files shown in the filelist of the big update (1.68 Gb) and install them on the device ?

Stock recovery wont have an option . There is no graphical UI for installation.
Downgrade or update is just a manual procedure.
In order to roll back , u need to install a roll back package and then the origional MM package . Using the three button combination

Ok so in the guide I found on the same page I linked in my previous post (the guide is hopefully written in english) it says that the phone must haven't been rooted or even unlocked, so I prefered to relock the bootloader (and completely reset my phone, for the third time at least in two days).
But then I realized I would need to have an unlocked bootloader for the flash so I unlocked it again, but now the device stucks on "Your device is booting now..." with no option at all whatever I do, whatever the buttons I push... I'll really start to think I'm simply idiot
I'm searching on how to solve this new problem and unbrick the phone... 'cause I can't even shutdown it, the "Volume Up + Power" combination while USB plugged in or anything else doesn't work this time.
EDIT : Okay so my phone seems to really be hard-bricked. My phone just stays at the screen "Your device is booting now..." with no option at all, I can't shutdown it, I can't enter recovery or erecovery mode. Does anyone know what to do or is my phone definitively bricked ?

But how can I unbrick the phone ? I can't enter in any mode, I can't connect it to PC, I can't shutdown the phone, I can't use ADB or FastBoot on it, I can't reflash the bootloader or install a TWRP, downgrade or boot normally, I can't do anything !
So how could I unbrick it ? For now it's just still displaying "Your device is booting now..."
If you know how to do, please tell me so I can unbrick my phone. Sorry for asking you so many things I don't understand myself why there are so many problems...

Huawei p9 lite 2017 bootloop

Hello, my young brother just bootlooped his new phone, he tried to root the device.
He was following this tutorial - https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
Unlocking bootloader went fine, then installing TWRP went (probably) fine, then the phone needed another factory reset. And since that moment, there is just "Your device has been unlocked..." and we can't do anything. Going to recovery is impossible. The battery is above 50% so waiting for it to go down on its own will take over a week.
We have a backup made with HiSuite.
I'm not really into huawei, so I've not a single clue what to do. Please, help us guys. Thanks in advance.

I'm not any good at such things, really. I don't want to brick the phone, that's why i'm asking you for help. And your help didn't enlight anything, really. So sorry for my ignorance, but I would be greatful if you could explain it in easier way. Thanks in advance.

Turn of your phone than HOLD Volume Down button than connect to usb than yout phone reboot into fastboot

That's what I try to do. Fastboot doesn't load when i hold volume down + power. I can't turn the device off because it just continously starts over and over again. The phone starts normally when battery goes down completely, system loads but then phone goes off due to lack of battery.

Sent me a massage after you going to Fastboot

I can't enter fastboot, it doesn't start. It just restarts and i see the screen "phone has been unlocked and can't be trusted, phone is booting..." something like that.

you cant enter fastboot, if you have not... do you even know, what you need to do, to enter fastboot? there is more than two thing to do, so, does you realy know what need to do ? call all thngs you need to do, to enter fastboot please.
got similar problems, because i instaled wrong custom recovery.
there are 2 sugestions, got in fastboot, im sure, its working if do it properly and instal proper recovery, for your model. second, use dc phoenis here
ps. why this post are in p9 not p9 lite forum?!

Well, I plug the device to PC using usb cable and when it's bootlooping I hold volume down and power button. That's how i was entering fastboot before. Now it doesn't work.
I've got stock recovery.

hold power button ~30 sec, force restart. even then nothing? well, if fastboot not working, then its gone. Ofcorse, there need to be a way, how you put on board files to work software, but im sure, thease things have only huawei.

The phone is just bootlooping, nothing else. If the battery goes down and i plug it to its charger I'm able to boot normally into the system. But once i try to turn it off it bootloops again.

Hey Guys,
I unlocked my bootloader and installed TWRP in order to try to upgrade to Oreo.
After a while i decided to just stop with it and leave it stock.
I relocked the bootloader, but now it is hangs at 99% factory reset. Rebooting the phone just brings it back to factory reset.
How do i get in to Fastboot mode to unlock the bootloader again and see if it will just boot up?
Tried different key combo's but it only boots in to the factory reset procedure.....

1. Connect the usb cable already with the pc
2. Press and hold vol- and the power button
3. Connect the phone with the pc when the screen turns black
4. Still hold the buttons until you can see the fastboot screen

Thanks! But i already tried that. Does not work. Always goes to Factory Reset.
Will let the battery drain for now and see what it does then.

i think you flashed the oreo compatible twrp on your phone this makes your nougat phone stuck in boot loop. Try to flash the nougat compatible twrp or try the stock recovery.

I had a problem just like this.
All I did was wait for the battery to drain while it was on the reset screen, and on next bootup it didn't didn't go to that screen.

I can't flash anything that is the problem. Cannot get it into bootloader or fastboot mode or anything.

I let it die, and then i plug in the charger and it boots. I see the initial setup screen but it then reboots again and goes to the Factory Reset loop again.
Guess i will keep trying

Ok i got a bit further.
When i let it die, and then plug it in it boots to android. But as soon as i reboot it, it will go back in to the Factory Rset procedure.
Also adb reboot bootloader does not send it to bootloader so i can unlock the bootloader.
I also tried putting firmware (UPDATE.APP) on an external SD card, but it will not do anything with that either.
Anyone any other suggestion?? Need to either unlock the bootloader, or somehow flash original firmware/recovery.

No unfortunately not. When it is booted after draining it, i can do adb reboot bootloader but it just does not go to bootloader. Just reboots back in to factory reset loop.

i think you already need to send it to huawei service center since you cant boot to fastboot.

I really hoped there was something i could do since it does bootup after draining the battery.
Somehow the factory reset procedure should be stopped so that it boots up after a reboot. There must be some virtual switch to set or something. Problem is i only have adb to do something.

I managed to fix the issue with a tip from another thread.
After draining it again i let it boot again. Then i did a factory reset from the settings menu.
The phone then rebooted and did a lowlevel factory reset. That also was stuck on 99%.
I then rebooted the phone by long pressing the on/off button. The phone then restarted the lowlevel factory reset and that succeeded.
Now its working normally again

Hello, I don't understand how you arrived to the menu to select factory reset. For me even if draining battery, it continues to loop in factory reset and stuck 99%. . can you explain the procedure step by step. thank you !

If after draining it still does not boot normally then this does not work for you unfortunately.

try to use this service firmware it will update your phone into B364
- put the dload folder into the root of a fat32 formatted SD_Card
- shutdown the phone
- While pressing vol_up + vol_down press power_on button the upgrade will be lunched automatically
if the file does not work please provide us with the exact phone model to get the correct file

Ehhhhmmmm...... I solved this already
I wrote that in a post too......

where is the solution to this problem
I have the same problem, what did you do to solve it?

Could not do normal boot. Invalid KERNEL LENGTH.

This message I get when I try to power up my Note 9 N960F/DS.
I got it this way: Been running the same ROM for 2 years. Time to upgrade. Upgraded TWRP via the app. After downloading the ROM image to SD card, I tapped an app called Reboot, with the Recovery option. I suspect this app is from some old installation, and ended up on this unit via data restore. Now all I get is this message on a black screen. No logo, nothing. Message flashes once. If I plug into PC, message flashes repeatedly. Cannot boot to recovery using Vol-+Pwr, Vol++Pwr ineffective.
I suspect I bricked the phone, but I seem to remember once breaking out of this 2 years back, I think. Any ideas, clues, anything?

Try this, power off phone. Press volume up and bixby button and while pressing buttons insert data cable, phone should go to downlaod mode. OPen odin and flash stock firmware.

OK, tried it, display showed the same message until I released the buttons, then flashed the message every 4 seconds until disconnected.

OK, got it into download mode, reflashed twrp, now it's in a boot loop. Will continue working this.

It took a few tries, but I not only got everything working, I restored my data backup and upgraded to Android 10. Thanks all!
