I have an HTC U Ultra and it suddenly froze last night. Upon rebooting it, it started until the HTC logo screen and then shut down. I tried several times but got the same results. As a last hope I tried going into the Recovery by holding volume button and power but the same thing happens here as well, HTC logo pops up ( a different logo, this one has a reflection under the HTC text, which means the phone did try to access it) but then it shuts down again. Since I cannot access the Recovery I cannot know what is going on. Kindly help me out in finding how I can access recovery mode or any other workaround.
I cannot use ADB either as it would need an opened phone with debugging enabled. Kindly help me out.

Since Friday I have problems with my phone.
Friday morning I couldnt turn off my alram clock, screen wasnt responding. I pull battery and phone was rebooting all the time (Hero logo -> htc logo -> hero logo etc.. ).
I have turn it on by pressing power button and menu key to launch safe mode. I have launched it then I have uninstalled freshly installed application rebooted the device and it start working properly again.
Today the same thing happend. But this time I cant turn on safe mode.
The proces of rebooting take few minutes not normal amount of time(very very long) .

Do you have a custom ROM or the stock one ?
I have stock rom .
But I have used the recovery img to upload(executed) the rom that was in the soultion in this post
forum. xda-developers .com / showthread.php?t=556038
I dont know what it did it just upacked and loaded the custom rom I think....
I have put originally RUU and still my phone doesn't turn on.
It still doing boot loop, this takes about 15 minutes.
I think I will call HTC support and return the phone for repair
Have you tried to boot WITHOUT SD in phone?
I was running Cyanogen 6.1 on my HTC Dream fine, after that i decided for full downgrade. So i searched google for it and found the cyanogen wiki for doing it. I followed each step and after flashing DREAIMG.NBH to my phone, it restarted. And so it entered a boot loop. I took off the batery and then tried to enter recovery or the bootloader.When powering the phone normally, i see the T-Mobile logo, and after that, the screen turns black. Whenever i try Camera + Power, after the logo it goes to black screen. Home + Power points the same thing and so does back + power. Fastboot doesn't seem to work even though i have all drivers properly installed and the Android ADB Device shows under Device Manager.
I know i messed up because i didn't wipe before the downgrade. If there is any possibility to repair it? If so..what is to be done?
Thank you in advance!
Hello,
my friend has a problem with his phone. He neither installed a custom rom, nor he rooted it. He updated OTA and after a week, while he was talking, the phone shut down.
When he powers it on the screen lights up and nothing else happens. Sometimes the vodafone splash came up, but nothing more.
I don't know if the phone boots into recovery as I don't see anything on the screen.
I tried booting to fastboot mode, and the pc detects it. But I whatever I try to do, (flash,erase etc) I get the error: Remote not allowed...
Any ideas how to fix it?
try a new ROM?
How? The screen shows nothing... And i haven't rooted it so I can flash another rom
did you try to turn it on and push VOL- to go into SPL menu
yes th screen lights up and but it shows nothing
I'm not a noob and have tried everything I can think of - hooking my phone up to my pc via odin and adb with zero results. Tried plugging on my phone overnight, etc etc.
My problem - I was at work and took a photo with the camera app, the camera crashed, then I opened the gallery. I went to reboot my phone and nothing happens. Now when I try to power on the phone, nothing happens. I do a battery pull and then put the battery back in and it boots up for no more than 3 seconds to the Samsung logo and then turns off. If I try booting into recovery, same thing - just turns off and the same situation if I try to boot into download mode. Has anyone encountered this problem? Note that I am running a custom recovery - Philz CWM. I fear the worst; my phone is perma bricked.
edit; FIXED - Faulty power button. Power button will stay in and not pop out without prying at it.
Hey,
I have D802 16GB with pre-last CM version. Wanted to restart the phone (no mods nor installing apps before, just a normal restart) and the trouble started:
-it was stucking on LG logo and then screen turning off; sometimes it came to CM boot animation followed by turned off screen
-managed to boot the phone in safe mode in order to backup files from the phone, it freezed and turned off. Booted in safe mode few times again, the freeze was coming faster and faster
-once or twice phone booted up normally, freezed very soon
-booted to safe mode couple of more times. I noticed the phone was freezing shortly after releasing the volume buttons.
-booted up in normal mode, was holding the volume up button during the boot. The phone worked normally, after couple of mins released the volume button. Few mins after the phone freezed.
-LG logo was shown few more times out of dozens of attempts with different power button and volume buttons combinations
-LG logo showed for a short moment after pluging the charger
-now nothing happens at all, even when connected to charger or PC. The computer doesn't detect any device.
I really want to get the data that are in internal memory of the phone. What should I do? What happened with my phone?
Found this:
https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
but will the internal memory data be affected? Moreover, there is written:
12 After attaching buttons plate,check your device going into download mode, and use flash tool to flash stock rom.
Click to expand...
Click to collapse
On the phone is CM which is not stock ROM, can I proceed?
Each advice will be much appreciated
