Power down, remove and reinsert your SIM, power up... Go to your Mobile Network settings and make sure CDMA/LTE or Global is set.

[Q] HTC desire X stuck in bootloader screen

hi! i have found similar threads, but they did not help me solve the problem, so here i am, writing a new one sorry guys. also sorry for my bad english, it is not my primary language..
i have an htc desire X which has a damage only on the outside display, the touch screen worked perfectly. then, all of the sudden the phone kept restarting, freezing for few seconds on the HTC welcome screen, then turning off again. it did that for about few hours then died completely, battery wouldn't charge either. on charge, red light on, no sign of life.
i have bought a new battery, and the phone turned on and did the same again, restarting every few seconds. i have pushed the low volume button + start combination, to have it go to the bootloader menu. since then it is frozen on that menu, stuck there. no buttons would work. they do work to get to the menu, but on bootloader not anymore.
i am a newbie, i dont know what to do, except for the fact that i have all contacts still in the internal storage and i was hoping to save them to an external disk/pc/microsd.
when i restarted the phone, the sim and the microsd were already out.
connecting the usb cable to the pc doesnt bring me anywhere either, my pc says "device not recognized" then it doesnt see any device.
please help me to get my data out somehow:crying:
little update:
this morning the "smart"-phone is not stuck anymore, i was able to get to the bootloader and select recovery, BUT unfortunately any attempt to push the on button to confirm it went wrong, phone keeps just restarting or freezes again on HTC welcome screen. any idea?

Xperia U 2G and screen going blank

Hello everyone,
I have a problem with my xperia U phone, yesterday the screen suddenly went blank, i could see some backlight but nothing would turn the screen on, pressing power button would restart the device. After some googling i figured out that this only happens after i enter pin number of my sim card and if phone is in 2G. Solution was to remove sim card, set it to 3G, reinsert sim card and then it was ok. I tried factory reseting the phone but it doesn't help. What could be done ?

Please, help me Developers

Secure startup doesn't recognize PIN code

Hi,
I have a problem with my LG G5 (but saw it happens in other LG phones)
I have a PIN screen lock and I changed it a couple of days ago.
I was talking on the phone when it restarted (I remember the battery was hot).
Now the phone is on "Secure startup" and I had 30 tries to unlock it (15 remained).
Can't add link because I'm new, screen from 2017 post on this forum, /showpost.php?p=71690001&postcount=27
I have the "white" screen (and can't get to the "black" screen, more details down).
I saw a number of posts on this issue.
I can only enter PIN (no character keyboard).
I tried the current and previous PIN. Also tried: 0, 0000, 00000, PUK code.
Some of those tried also on safe mode.
When tried to fill the screen with zeros as much as possible and tried to unlock, I got a screen that said something like (translated):
In order to open the lock, turn off the phone and power it on again.
Did it but didn't change. Than I thought I should have pressed restart (instead of turning off and then on) but didn't got to this screen, just stayed on the same screen with one try less.
I can get to factory reset, only this option yes/no (can't add link because I'm new, on Youtube: /watch?v=6rQNENaJYZg)
I don't want to hard reset because some files are not backed up.
Also can get to Fastboot mode and Download mode.
If I restart (or power off and on) the phone is on flight mode.
I can call to emergency numbers, and when I call and hangs up, suddenly there is a cellular connection and 4G data.
In this situation I can receive calls, but still can call only emergency numbers.
The phone is not rooted and I don't use special ROM or something like that.
From time to time it makes tick sounds (like pressing a button) every few seconds. The rest of the time it doesn't make any sound.
The computer recognizes the phone and installs the driver - "Android bootloader interface" but I can't see the phone on my computer.
Also tried to connect through Google Find but it can't locate the phone and the lock option there doesn't seem to do anything (writes request sent).
There is a problem contacting stores because of the Corona.
Appreciate any help,
Thanks very much!
Edit: I also have a memory card, do you know if the data on it is OK? (I don't have a card reader)
