U12+ Doesn't turn on! - HTC U12+ Questions & Answers

Hi, my htc u12+ suddenly doesn't turn on even if I plug it to charge, no led turns on. I tried volume down + power, volume up + power, volume up/down + power, nothing! It's dead! What can I do?

Dang sorry to hear this, if you connect the phone to a pc, does the phone show up in device manager as a MTP device? If it does you should be able to use ADB to fire it up in at least recovery or bootloader. If not then yoibare looking at a dead device and maybe the battery or usb port may need to be reseated/reconnected.
If your on a custom firmware with modified bootloader/recovery like TWRP or Magisk you may be able to do some stuff in linux but i would refer you to the custom rom section for that.
Either way good luck.

Phone will not go into CWM Recovery and automatically enters download mode with USB

Okay guys, I have an annoying problem. My phone after the ICS update does not want to go into CWM Recovery with the Power button + vol down (or up) method. I can never get the darn thing to work. It just loads up until the white samsung logo and then goes black and just vibrates. Any idea what could be the problem? It's an issue because it means I can't root or anything since stock won't allow me to go into recovery. The only way I used to get into recovery was through rom manager and I obviously need super user permissions to do that.
Another thing is, whenever I power on my phone with the usb cord plugged in, it automatically enters download mode. I know you're suppose to hold certain buttons but I just power the thing on and it goes straight to the DL mode screen. I'm thinking these two things could be related.
Any idea on how to fix this? I went back to complete stock and it didn't do a thing.

My phone was being a bit finicky with this as well, I found the below sequence to work for me every time.
Press and hold both vol+ and vol-
Press and hold power
Wait until phone is vibrating once every couple of seconds
Release power
Release vol+ and vol-

u need to b specific to get proper help.
u stated "Either way, the methods don't work ", specifically what methods r u talking about, there is only one method in using the buttons that works as RabidSmurf has stated, but first pull battery and dont keep usb plugged in, if that didnt work redownload cwm, check the md5 checksum and reflash using odin
To get into download mode I'm holding power+vol up+vol down
after the phone starts up release the power and keep holding up+down.
Let me know how it works.

Make sure it is not attached to any USB. Not even the power outlet because it will take you to firmware update mode (download mode) and hold up down volume keys and power until you see the white Samsung logo. good luck!
i had to deal with this when the firmware failed to ugprade for some reason, what i did was download odin and the stock rom and flash it with odin, i was back up in no time
Not booting
Frnds plz help
After flashing am n m same soc chipset custom rom my phone is not going in cwm also another problem is after pressing the power button the phone screen is gping black n then boot audio is playing but phone is not booting completely.
To be more specific i have cqnvas 2 plus with mt6589 and pne site there was eom name note 5 evolution for a116 hd with same soc i.e. mt6589 hence i flashed the rom it flashed succesfully also but then the problems occurred.
Plz help me fast thx in advance.

LG G2

ok, so after rooting and trying to install CWM, my phone will not boot, only blinks red light. I think when i was trying to flash img files over to the phone, i lost connection and wasnt able to transfer the bootloader.imgs to the phone. Following this, when i plugged it in, i would get numerous drives trying to open, but said they needed to be formatted. I then tried the UBUNTU method, which led to my phone not even being recognized... but my question is, why is it so tough flash a recovery to the phone now? I remember when I had my S3, it was much easier to do this....i have a lg g2 if that helps....i have tried all the guides, and like i said, all i get now when i hold the power button and volume down, is 8 blinks of the red light...has anyone had this problem, if so what did you do to solve the problem?
Can you get into download mode?
Power completely off.
Plug the Usb cable into a computer.
Hold vol-up while plugging in the Usb to the phone.
If you can get that, then you can use LGFlashTool to reset.

How do I fix my OnePlus One’s bootloop?

Greetings of the day,
Hello everyone, I'm having a oneplus one 64GB phone that is not getting start, everytime i connect it with the charger it goes into a bootloop. Yes the phone was rooted and I was using a custom ROM with the default kernel. The issue started when I tried to reset the phone to battery settings. I think I somehow messed the kernel and now it is stuck in bootloop. The problem is that I can't connect it to my computer or put it in debug mode as it just restarts again. Any idea how to actually boot it so I can install the kernel and ROM again?

No, My phone is not getting on but whenever i am connecting it with my charger the phones goes in the Bootloop, and when i am connecting it to My PC while pressing Volume Up + Power Button Pc shows that the Unrecognized devices has been connected.
And i think phone is Hard Bricked. I have tried ADB software and one plus 1 drivers manually but it didn't worked too. I have tried minimal ADB too but it also didn't work.
Kindly let me know about it.

Volume UP + Power should boot in fastboot mode. Volume Down + Power should boot into recovery. First, try to boot recovery.

I have tried both, but nothing happens with it, Volume UP + Power shows the unrecognizable device is connected and Volume Down + Power does nothing it continues with bootloop .
Have you got Developer Options enabled?
Goto About Phone & Tap Build Number until Developer Options is activated. Goto Developer Options> Advanced Restart & enable the switch.
Press power button->Restart->Recovery.
It will now boot into Recovery.
Also have you tried keeping hold of power button whilst it bootloops. Keep holding the power button until it powers off. Then press Volume Down & Power Button to power back up (you might see a slight flicker onscreen that means it should go into Recovery mode). Keep hold of these buttons until you gain Access to Recovery Mode.
This will allow you to Recover or flash a different ROM.
If you're having issues connecting to a computer (Windows) try downloading Windows Media Center for your version of Windows. This will install media drivers to recognize your phone.. If all went well you will get the pop up with A0001 (Codename of OnePlus One). From there you should be able to enter fastboot mode through ADB.
If this doesn't help you, I'm sure that someone else will untangle the puzzle to get your device in good working order buddy. Good Luck.

Help - my honor 8 was block - No access Fastboot Mode or Debugging Mode

Hello,
I downgraded my Honor 8 via Rollback and installed the Rom FRD-L09C432B131.
But my phone is stuck on the blue Android startup screen.
I can not use the Volume +, Volume - or Power buttons.
All I can do is let it turn off by itself when the battery is at 0%.
When I put it on, it turns on by itself. Arrives on a blue screen. Reboot once and then stays eternally on the blue screen while heating up enormously.
I have no access to the Recovery, erecovery or via the computer (by plugging it into a USB port).
Thanks

Once your phone turns off, press power button amd volume up button together. This should take you to recovery. Or you can't access this at all?

I can not turn off my phone. It goes off when the battery is at 0%.
If I put on USB or mains, it recharges and restarts automatically. And I can not stop it ...
When I plug it into a USB port, the Power, Volume + or Volume buttons are ineffective.
And when it's plugged into the PC, it does not show up!
So I do not have access ... except perhaps by a software that would force the connection ... or a manipulation other than Power / Volume ..
When I say reboots, it is a program to display the Android blue screen and hangs on it!
does it say android or honor?
going to dload is kinda tricky sometimes and should be done when connected to wall adapter, not pc
can you keep vol- and power pressed while your phone is connected to pc. keep them pressed even after the phone restarts. dont let go. it might take some time. does it go to fastboot?

He can't even boot to recovery.
Sent from my Honor 8 using XDA Labs
Ohhh, sorry my bad
dats prolly because he has mismatched files for the os he's running. he should deffo check if he can go to fastboot. the fact that he cant go to dload doesnt really mean anything because i cant do it either 40% of the time. its a bit iffy. the fact remains, if it boots to honor logo, means some type of os is up there. if he can go to fastboot he can flash stock recovery/recovery2 and try dload again. without proper recovery combo he wont be able to flash anything anyways and warranty prolly wont cover it since its users fault, esp if he has unlocked warning.

Thank you :laugh:
Similar to me, only way is go into bootloader mode, then charge the phone for awhile, you cant do nothing cuz of 0% battery, flash stock recovery, update via dload or direct wifi recovery.

He can't go to fastboot
if he completely bricked it, he'd be stuck at black screen/android logo, not honor logo. either he's not telling us everything (ran out of juice while upgrading / error while flashing / flashing wrong rom), there is no chance all key partitions got wiped if the process finished successfully. meaning at least he should be able to fastboot cause thats the first thing flashing alongside bootloader. no way any type of system partition is up there, and bl/fb is not, even if they are from a different OS. h8 can be stubborn at times, but keeping the cable in pc and holding vol_down+power for good 20s deffo will force it to at least reboot. thats the only way. if this doesnt work, you should take it to a service center.
I guess it's better if he takes it to the service center
Nothing works. So I have to send it to the service center
Thank you all !

Question I can't access the Recovery Mode

Hi,
I do own the S22 Ultra Exynos with 12/256 GB Memory,
I already tried several times to access the recovery mode to wipe out the cache partition
( powering off the phone, holding the power button and the volume down button and releasing both
as soon as the logo appears) but it doesn't work...
Anyone having the same trouble ?
Kind regards,
Valy

Try volume up (+) & the power button.....
I already tried that too, doesn't work either...
In the good old days, you used to have to have a usb plugged in to access recovery (and at one point actually also be in a recovery programme on a pc, or use a hacked together usb jig to do it on the fly). I would be surprised if they have gone back to that, but might be worth a try?
Turn device off,
Ensure one end of your USB Cable is plugged into the PC / Laptop
Press Power + Volume up
While you press both Power and Volume up insert the USB Cable into the phone.
Keep pressed and you should enter into the recovery, You used to be able to do this without the USB Cable, but recent changes made you require to plug it into a device.
Unsure if you can do this using a normal wall plug, i have never tried it.

Maybe it's an Exynos issue, I just booted into recovery with the volume up & power button combination (no plug-in of cord needed) on my Snapdragon-powered S22 Ultra.

update?
Hi All, - I had the same problem, it would just not go into recovery mode. however a slight twist i saw on a website says to do the following and it worked first time much to my suprise..
basically the phone has to be powered on to start the process..
1.HardReset.info: At first, connect the device with the computer by the USB Type C and push Volume Down + Power button to switch off your phone.
2.HardReset.info: Then press Volume Up and Power key for a short while.
3.HardReset.info: Let go of all buttons if you see the SAMSUNG logo
4.HardReset.info: Now use Volume keys to select Wipe cache partition and confirm with the Power button.
5.HardReset.info: In the next step go to Yes option.
6.HardReset.info: At last, choose Reboot system now by using the Power button.
good luck..

Hello.
That only works with the included USB Type - C cable. It doesn't work with a USB type A cable. Both ends should be Type C.
That's why it didn't work for me earlier. I tried numerous times using the old cable from my Galaxy Note 9.
