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.

I've got a 4G Xoom, that I bought new about 13 months ago. It's been great to me so far. I had it rooted and was running CM 9 on it and had been doing so for about a month without any issues.
Yesterday, it was plugged into the charger and I happen to glance at it and it was doing some strange things with the screen, flashing on/off, black lines on part of the screen. I powered it off and left it alone for an hour or so.
Since then, it's been completely unresponsive. I've tried Vol Up+Power button countless times without it working. The charge light (white) came on briefly while plugged in, but then went off, never to return. The only reaction I can get is that after holding Vol up+Power causes an orange light next to the front camera to blink twice. That's it.
Any suggestions? Is it completly dead?

Given that it's sealed, how is this done? I hadn't even considered cracking the case.

You may not need to remove the battery as several people have reported success with just slipping some paper between the contacts for 30+ seconds. You will need to open it up though and here's a post with info and pictures to guide you through that: http://forum.xda-developers.com/showthread.php?t=1578365
On edit: here's another thread with good info for you http://forum.xda-developers.com/showthread.php?t=1528706&page=3
Good luck.
Well, I did the paper under the battery terminals for 15 minutes and still no joy.
One item of note is that when I plug the charger in, I'm not getting a white (or green) light. At least not much of the time. Occasionally, I can wiggle the plug a bit and it will light up, but I'm not getting to green at all.
I can put a multimeter on the battery leads, does anyone know how many volts/amps I should be reading?
Are we sure that its not just a crap connection with the charging plug. It is a wimpy little pin and my Xoom needs me to do a rain dance to get it to charge. I have to plug it in, wait a few seconds and then the white light comes on , but only if the wire is flipped back over the top of the screen. Another thought is I use Tiamat ics and there is an option to have the light on or off during charge and I think it is set to off as default, maybe you didn't set that up. I would bet its something stupid and you just need to keep playing with the wire and see if you can get it on. Good luck.

hi everyone, I have a challenge for you...
My MZ604 Wifi Xoom is completely unresponsive. No boot logo, no screen nothing.
A few months ago I flashed a US stock to get a hold of the ISC update. it went off without a hitch and I was very happy with it.
A few weeks ago I picked it up and it was black and not booting, even to the logo. Nothing.
The only things that light up are the white charging light when it is plugged in.
When I plug in the USB (Win7x64) it registers as a Motorola Flash Interface and charges through my computer- but not all the time.
I have tried many combinations of button pressing and holding, and the only indications I get that it is working underneath the black screen are the white front light going on and off and the device registering in device manager.
Oh, and it makes the battery low sound when low on battery, which i hope is a good sign.
Adb fastboot does not recognise the device no matter that I do.
Has anyone ever come back from this???
Desperate,

This might be a case for the Motorola Programming cable from the Black Hat Team (google it). You can also make one. There are instructions somewhere in one of these threads.
Have you tried to take the cover off and remove the batter(ies)? Look for the thread with instructions for that. You will need a Torx screwdriver (#5?).
I'll bet you can bring it back.
thanks okantomi,
I just ordered a torx set, hopefully a battery disconnect will work.
Very hard to figure this out, every single search i made for 'bricked xoom' came up with silly buggers with frozen boot screens. Not a real brick at all...
If you don't hear from me again, assume it's fixed!
Thank again
Good luck!
We havent hear from you since so hopefully you fixed your xoom!
Can you share your experience for whoever has simmilar issue....
Thanks
&
Good Luck
Hey,
A few months ago I unfortunately dropped my phone so the screen was up to no good.
I left it for some time until I found a new screen on the ebay for decent money.
I changed the screen (LCD + glass) by the guides on the youtube.
Unfortunately there is no screen activity or any other interaction after that.
I can get the blinking orange led when connected to a charger or PC and after a night of charging the led turned green.
When I try to turn it on theres no ordinary bottom row buttons flashing or anything else.
I tried booting it into bootloader via PC but still no luck. Computer can't connect to the phone.
The motherboard gets warm and the led blinks so it shouldn't be dead.
Does anybody have experience with that type of situation? Would hate to lose my phone.:crying:
So at the moment if I turn it on it just randomly vibrates after every 30 seconds lol.
Somehow if I fiddle around with the power button for long enough I can get the bottom row white leds to flash but thats all.
If I hold the power button hold long enough, the flashing stops and the charging lite turns from green to off or orange.
Can it be that the S4 screen doesn't fit on S3 or something like that? By visual comparing they look the same.

It maybe because you have a s4 screen on a s3 phone or vice versa I believe that the s4 screen draws in more power so the s3 might not be able to give it enough don't quote me on this I just think this may be the answer

Not so sure on this. On the visual inspection there are no difference and I can't really get the phone as far to even show anything.
Any ideas?
My myTouch worked for a really long time, even while overclocked. Today, when I was playing a game (Minecraft) it gets much hotter than normal. So I place it on my fan, just a floor fan, to let it cool down. Once it's cooled down, I resume my game. Out of nowhere, it just freezes and shuts off, then restarts, then turns off again once the BIOS splash goes away. It doesn't power on until I press the power button, then it only runs the BIOS splash and shuts off again. I try again, and it powers on to the boot screen, and then it shuts off again shortly after. I try it again, then just BIOS. And yet again, then a successful boot after letting it charge for about 10 minutes. I take a shower and when I come out it works fine, but 10 seconds into use, while I pressed the Bluetooth notification drawer widget button, it freezes and shuts off. From here on, it won't power on at all. I plug it into computer, nothing. All that works is the dim red LED on the trackpad. I press the power button, trackpad light turns on for a few seconds, then off. I press again, turns on for a second then off. When I hold the power button, the light is on and blinks every 10 seconds. No key combos work. Charge light does not come on when plugged in to either computer or wall charger. Any fix for this?
Not a fun situation, very possible your emmc is fried but there is a chance its just the battery. Let it charge overnight and if possible test a new battery
But there is a high likelihood you're going to need a new logicboard
If you're after a new device I do have a few oneplus one invites left...
Best of luck!

I have a very similar problem, i recently came across the mytouch 4g slide in the closet and remembered that it died due to charging overnight, 2-3 years ago lol, well the phone still does what it did after it died, no vibrations screen etc, the only sign of life is the two red lights one at the top left of the screen and the trackpad, could this be just the battery that got fried that night? Should of gotten this fixed those years ago but just got a new phone instead.
Possible but could also be a sign of a bad logic board
I have an extra one if any of you want it, not selling it, I can just mail it to ya, PM me about it, whatever. It's got moderate chips and dents, but works fine except sometimes the soft keys don't always work and you have to restart the phone. It has the latest CWM recovery and the latest 4.4.4 ION ROM. No SD card ships, but baseband and all wireless works, but uh, it's SIM locked and S is still ON. Bootloader is unlocked. I'll give you an extra screen and an extra battery, too.
I fixed the one I posted this thread about after I realized I could buy a new motherboard directly from HTC with a few hidden strings pulled (I'm just that special) and before that I ordered the one I'm talking about now that I'm trying to get rid of on Amazon.
So, yeah. best way to fix one is to get a new motherboard, the one from HTC's old stock warehouse that I got took a week or so to ship, and I cracked the casing opening it and almost ripped a connector ribbon, and I also think that this phone surpasses the G1 as the most mechanically intricate device I've disassembled. I've done a few, but man, this blew the top.
Never thought I would run into this moment that I need to ask for help on the forum, but I guess this is my last hope.
Here's the story:
I was on Oreo firmware and thinking of going back to Nougat because there are some apps only work on Nougat at this moment and I overall prefer Nougat design.
My phone was on S-off so I thought it would be perfectly fine for me to just flash Nougat firmware then flash the Nougat rom I desired like the good old days.
So then I launched Sunshine app, passed the compatibility test and the phone rebooted to download mode with S-off shown, everything was working fine so far.
And here was the problem happened, I typed in the command"fastboot flash zip firmwareXXX.zip".
Terminal showed error needs to reboot and flash again immediately as normal, the phone rebooted but never come back to download mode.
Now it only stays on black screen, if I tilt the phone a bit I can see the backlight glowing.
I've tried hard reset by holding power and volume down, it will reboot but still stays on black screen, neither system nor bootloader is accessible.
Even plugging to the computer detects nothing, not even QHSUSB_BULK mode.
However, the phone is able to charge though, I hook up the usb cable with a digital meter and it shows 5 volts and 0.5 amp.
I'm running out of solutions, I've searched through the entire forum and see no one has the similar experience.
This is the first time I hard brick a phone, been a loyal HTC user since good old Desire HD days.
If anyone has experience or solution for this, a kindly help is appreciated, thanks!

Have you held the power and volume down button both together for exactly 1 minute,
I have a u11 that took for ever to reboot with corrupt os youll notice the capacative buttons start flash if its doing something or going to reset after about 30 seconds if not and nothin happens
Take the backing off and unplug the battery,
To do this heat the backing up with a hair dryer and get some really fine guitar picks, work your way arround slowly, in my case the U11 was not glass backed only plastic and was original backing ive heard they are glass now though so be careful,
Now with the backing off and exposed, take all of the 5 or 6 screws out from the plastic ariel cover with NFC chip attached (chip is gold bend it up off battery it is not glued down)
Then from the left of the device at the bottom of the plastic cover with ncf chip on it you should see a slight gap where the vibration motor is located and sits
Get a rounded pair of tweezer and insert just the tip into the opening and very carefully pry it up, it make take a while as some of the adhesive from the backing will be holding it down,
After that is off you have now exposed the devices PCB,
From the battery youll see the connector making its way to the PCB port disconnect it and reconnect it now try to boot directly to download mode with
Power
Volume down
Both at the same time, if this did not work the disconnect the battery again and wait 24hrs for the static electricity to disperse and try again, had this work on a completely frozen unresponisve evo 10 and u11 + and also my U11
Still no luck id say the emmc on the board has gone haywire either that or possibly one of the thermal transistors has blown in which youll see either black and burnt or white and powdery,
Im a phone tech you shouldnt have any problems doing all this just take your time,
Good luck mate

I've tried holding volume down and power buttons both for around 5 mins, no capacitive button blinking.
However I can tell the phone reboots several times during the procedure by seeing the backlight goes black and light up.
And about the reconnect battery route, I guess I'll just do it anyway, since the repairing price might be the same as buying a new one.
Thanks for the reply, mate!

Sounds like the logic board is trying to initialize but there isnt sufficient power to boot it,
its kinda like when you take the battery out of a phone then plug it on to charge without a battery and there is nothing but a lit up black screen and nothing else happens as theres not enough power to boot, this sounds the same to me as there are no red or green light after the orange when plugged in,
Get a hair dryer and heat the back of the phone up a few times and then plug it into charge to see if you cant boost the cells back to life, do this a few times,
If no change id most certainly suggest removing your back cover and unplugging and replugging the battery, once unplugged leave it for a few minutes, then plug back this will refresh the chips (especially emmc as this contains your entire system and bootloader, including download mode, RUU mode)
as soon as battery is reconnected plug it in on charge and try to boot it to download mode straight away also look for any change in the batteries light colour and any blinking,
the orange light when first plugged in is normal but should blink once or twice only then change to a solid red for discharged and charging or solid green green when near on 100% charged
If the above does not work disconnect the battery for 24 hours and try again, this will fully drain any static electricity in the device that may be lingering,
If still nothing after the 24 hours buy an OEM battery from ebay and install yourself, once you have the back cover off youll see the battery takes up 3/4 of the phones actual internal size,
Same as the back cover get your hair dryer place a shamwow or thick cloth over the PCB board then heat the battery up (NOT TO MUCH THOUGH only so its hot to the touch), then with the really thin guitar picks again (they should be bendable easily and flexible) work your way around the battery to cut through the adhesive securing it down,
CAUTION be very very careful the adhesive is strong keep the battery heated at all times to avoid pericing the battery and or damaaging the lcd as this is what its secured to, just take your time and work slowly do not force it out, once all the adhesive is cut it will remove easily by using the guitar pick insert between battery and housing and gently turn the pick from left to right and will pop out, (you will see the battery move when using pick from left to right if not you havent cut the adhesive properly work around the battery once again until you get movement from it)
Sorry for the long reply haha but dont send it to htc they are absolute rubbish hope this helps ive tried to be as detailed as i can its actually alot harder trying to explain it than it actually is to do it

what should i do now, please help me, and sorry for my bad english. Thanks a lots
