Hi Everyone,
I'm have a problem with my One XL. It's an Australian Telstra item. I got soaked in the rain and the phone got wet. I put it in rice for a few days to soak up the moisture, then charged it up. After this the screen backlight would intermittently fail, and i noticed if I squeezed the LHS of the phone it would sometimes make the screen go on or off. The problem got worse over the space of about an hour and eventually the screen would not come on. I opened up the case, and noticed there was a split in the ribbon cable that is part of the screen at the point that it is folded over 90deg (I'm not sure why this was never a problem before the phone got wet?)
So I stupidly got straight stuck into taking it apart to replace the screen before backing up all my stuff. I ordered a new screen of ebay and replaced the old one. Now I am having the following behaviour:
1-Press and hold power button - Phone vibrates once, then does nothing. Screen doesn't come on.
2-Plug into PC - LED flashes red for a while then goes solid red. Screen doesn't come on. Nothing pops up in "My computer"
3-Press and hold (~10sec) power after 2 - Red light goes off. Phone vibrates once every ~30 seconds. Screen doesn't come on.
4-Press and hold power after 3 - Home/Back/Apps LEDs flash 20 times, no other change.
I also tried a number of combos of power + vol -/+ with no success.
Also, I was being lazy and doing this without putting the case back on, and my power button has fallen apart. It looks like that ribbon cable is only ~$5 on ebay, so no big deal, but means I cant really do anymore troubleshooting at the moment.
So I guess the big question is, can the phone still be salvaged? I'm thinking maybe it's stuck in a boot loop with the screen also not working?
Any help is greatly appreciated.
Cheers,
Chris
The first question I have would be did you make sure you got the right screen? There are three different types of screens that came on this phone and you need to make sure you match it correctly. You can identify the type of screen by the colour of the flex cable attached.
Secondly, you should never use the power + volume up button combination, I'm not sure where you saw that information but it puts the phone into Qualcomm download mode which you definitely don't want. The only button combination that should ever be used is power + volume down.

Hi Timmaaa,
Both screens had the same orange/brown flex cables. I did read that there were different screens, but had thought there were only two and that the other had a green flex, so I definitely didn't get that one. Are the other 2 colours close?
I'm not sure where I read the power + volume up thing as I have read a heap of different threads. What would the expected behaviour be if I had put it into that mode?
Thanks for your help.
Cheers,
Chris
The three different screens have very different colour coding on the flex cable, so matching should be a piece of cake, which I believe you've done correctly. Putting the phone into Qualcomm download mode is kinda like a bricked state, if you're getting the red charging led and the cap button lights flashing I think you're ok.
Another thing to note is that you usually need to sync your new screen when you install it. From memory I believe you need to power the phone on, remove the old screen while the phone is on, and install the new screen while the phone is on. If you didn't follow this process that might be why your display isn't working. Other than that your phone might have just suffered some fatal hardware damage due to the liquid ingress, which isn't going to be fixable.

Thanks again Timmaaa,
I had a closer look at my old screen and it does have the small green section on the flex cable which I didn't notice the first time around. Bugger.
So i disassembled it again and swapped back to the old screen. The display still doesn't turn on, but the phone itself now stays on and the computer recognises it! I'm transferring all my photos across to my computer now, then I'll try to sync it properly and see if that helps.
Cheers,
Chris
Ok so I swapped the screens back and forth with the power on, and now it's working! Thanks Timmaaa, I would never have guessed I needed to have the phone turned on in order to swap parts, seems pretty weird. Now just got to get a new power button.
Cheers,
Chris
Awesome. Glad to be able to help.

Hello,
Had a perfectly fine HTC 8x till this morning. Then the pet at home chewed on the USB cable while the phone was charging .. I suspect the power cables may have shorted with the data cables. In any case, now the phone is totally dead when the charger is disconnected. If I reconnect the charger (new cable) then the phone vibrates, afer that the screen lights up for about 10 seconds with the HTC logo and then it switches off - it keeps doing this till the time I remove the charging cable. The Red charging LED does not come on at any time. I have tried the hard reset with Vol down and power key etc. and that did not work. Any help to revive the phone would be greatly appreciated.
Thanks & regards

I bought one listed for parts on ebay a while back that would do a constant boot loop. what i did was buy a cheap phone tool kit 2$ off ebay as well. removed the rear shell on the phone. dang phone is held with sticky adhesive. its take a minute to separate the housing and screen. if you have watched those videos on youtube where there using a blow drier to heat the plastic to take the phone apart is completely nuts. It only takes patients and dont force it . then disconnected the battery. 2 whole screws. woo hoo.. i couldn't do the hard reset either because the phone woudnt charge in off-mode. just constant boot loop. i had no choice to battery pull. strange thing was the charging light would always stay on even when it was unplugged. once the battery had been disconnected from the pcb it hasn't had any problems.
T-MOBUS HTC 8x Developer Unlocked, Sim Unlocked, and Running Windows 8.1
[SOLVED] Disconnect the battery from the phone for few seconds
Problems faced:
1. Boot Loop
2. Factory Reset using Phone buttons never worked, tried everything and never ever got the " ! " icon
3. Phone keeps restarting showing the HTC logo without "quietly brilliant" ( if you don't see that probably not going to boot the OS)
4. Phone does not work at all unless connected to phone charger
SOLUTION:
After trying almost every possible thing i got this to make it work.
1. Open the back cover ( you will need a hair dryer, check YouTube)
2. Unscrew just the two screws at the bottom of your phone and disconnect the clip-pin thingy (this connects the battery to the phone) for a few seconds. ( it has a metallic cover kinda thing)
Press the power button and your phone will go back to normal.
Make sure you connect anything that gets disconnected in the process... they are quite strong so dont worry, nothing will break or cut off, but do be careful.
hi there ok i found a solution you need to take the cover off and the plug in the charger because a button is stuck
there is only 2 screws you need to unscrew and boob it works

MY CASE... I've posted a thread explaining that...
This procedure works.. but in my case not at 100% fine... cause i can't insert back the sim card since the bootloops return if i do it...
That left us with a software issue i've not been able to solve yet...
Best regards...
Hello I'm using HTC M8 on GPE 5.1 rom.
Does anyone know of an xposed module or any other means to turn off all gesture/proximity features? I want the screen to ONLY turn on when I hit the power button.
The screen keeps turning on in my pocket for notifications which then causes but dials or emergency calls.
So does no one else have screen on issues when phone is in their pocket?

I can't be sure about the diagnosis of your issue, but in my case, I used to have a similar problem with my Galaxy Nexus
When the phone thought it was charging, it would light up in my pocket. The problem was that I had been using different usb cables to charge the same phone. And one of those usb cables had bent something in the micro-usb female slot of my phone. So the phone would randomly light up and go to sleep even when I wasn't touching it.
This not only caused the battery to drain more quickly, but when the phone lit up in my pocket and I was accidentally touching my activated screen, it would do all kinds of things in response to my touch. The short-term fix was to enable the lock screen on my phone (which I didn't like having) and set the debugging mode to stop turning "on" the screen all the time when it was charging (which is a setting I usually have on all the time because I am a developer). However, this didn't solve all my problems. The screen still lit up in my pocket from time to time, even if it didn't stay lit up for long.
The longterm fix was to use the same micro-usb to usb cable (the one that looked the closest to the original cable that I could remember) every single time with the same exact phone. And that eventually did the trick. I also looked into replacing the component in question, but I didn't have to go that far since the simpler solution worked for me.
I was replacing my Huawei Mate 9 screen assembly the other day. When finished and tried to reassemble everything back, I accidentally shorted the battery connector on motherboard, which there were some sparks.
Then the phone does not turn on anymore. Every time I tried to turn on the phone, it only came up with red flashing notification LED and the screen shows a Red Lightning Bolt in a Circle. After that, the screen went off.
Tried replacing the battery, the USB Charging Board, still the same result.
Has anyone experienced this before and fixed it?
Thanks in advance.
Hi,
Phone : RedMi 3S Prime.
Problems observed :
(1)When charger is connected, phone immediately makes short vibrations in a pattern (short-short-long-short).
(2)screen wakes up to battery showing 0%, then in around 5 seconds it jumps to 100%
(3) sometimes shows Mi logo, but does not boot.
(4)power button does not always respond.
(5) At some occasions red led blinks when charger is connected.
(6) Phone booted normally when switched on, after a few days it was kept idle (after a week since this problem started showing) I was able to use it, on battery without a charger connected to it. Now its back to the odd behavior.
I am looking to experiment with this, but have no idea how to. If there are any link suggestions or workflows, kindly help.. thanks in advance.

Seem to me that the battery needs to be replaced.
As for the power button not responding, there may a mixture of water/sweat/oils/dirt/dust that has worked it's way into the power switch and is intermittently interfering with the buttons normal functionality or it may even be stuck/sticking. If that is what is going on, you might be able to fix it by using a cotton ball and alcohol then rubbing over the button to get some alcohol to work it's way in around the button, then repeatedly and quickly tap the power button, then rock it back and forth from one edge to the other, then repeatedly run the tip of your fingernail back and forth quickly across the button, making sure to slide completely across so that your fingernail slides completely off the button so that it tries to "pop" up. Doing this enough should remove enough dirt to allow the button to function normally, if that is the issue. If you can remove the battery, it would be best to remove the battery before forcing alcohol in around the button or let the battery run completely dead before you try it if the battery can't be removed. Then let it dry thoroughly before reinserting the battery or connecting to your charger, the alcohol will evaporate completely away, you just need to give it time to be certain it's all gone before reapplying power to any of the hardware.
