[Q] Catch 22 - Desire got Wet not have 3 issues!

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks
Brisgstfer

UPDATE
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks

May be a hardware issue. But try installing a lighter ROM like dGB or MildWild and see if the issue persists.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!

Flash a ROM which can be unlocked via trackpad and volume can be adjusted from the phone settings without touching volume keys and the power button on the top.
I recommend MildWild5.8 based on CM7. When I was on it, I totally forgot about volume and power keys because all the phone operations can be done without them.

Thanks thats a great suggestion. I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?

Brightness stopped working and black screen after wake up.

Hello.
Suddenly my phone decided to stop activating the screen after I press the power button to wake it up, but the soft keys light up and screen is working even though I am unable of seeing anything.
Also the brightness function not working as well.
Any idea how to fix it or should I send it back to LG?
PS. My phone is not rooted and running factory 4.1.2

I bought it 12 days ago but I was wondering if it has to do with some settings to avoid the fuzz...

explain !
working screen but you cant see anything
brightness function not working on a dead / black screen?

No.
Let's take things from the start. Assuming that the phone is off when I open it the screen is fully functional. As soon as it goes into standby mode or by pressing the power button or after 30 sec or 1 min according to users settings the screen won't start again when you press the power button to wake it up.
As for the brightness setting is not working at all either I choose automatic mode or manually. I can only access the settings when I power on the phone when it is off.
I hope now it is crystal clear.

Try reformatting with new kdz

should have waited or my reply... we are not in same timezone. anyway its seems bsod a simple wipe or even kdz flash would confirm any hardware issue.

Thanks for the reply I will let you know as soon as I take it back....

Was the issue resolved?
Hi,

It did not help me
I got the same as OP problem on my stock E971.

screen can't turn on without force reset (P600)

I bought my device (P600) a few month ago,
and suddenly (without changing rom/karnel or doing root) i got a big problem -
when i push the button that close the screen(turn off the screen but the device is still on) or if the screen is turned off automaticly, the screen stay off forever. Even pushing the power button doesnt turn on the screen.
The only way to turn the screen on again is to reset the device (by pushing the power button long press).
I almost sure that the problem is a hardware problem even that it's look like a software problem because after i saw the problem i changed the rom and the karnel to other option to check if the rom/the karnel is the problem and the problem didnt solved.
Someone have a clue which element make the problem?
Thanks (and sorry for my bad english)

I'd bet money on it being a backlight issue.
Test it again in a well-lit room with a bright lock screen wallpaper, something with a lot of bright color. Once the screen turns off, wake the device and look carefully to see if you can see anything. You might have to tilt the screen, but you should see a very faint, dark image.

Amazing that's was the problem!
There is a way to fix it? What is the component that causes this problem?
thank you so much!

Unfortunately I don't know of any solution other than sending it in for warranty coverage or replacing the screen yourself.
I've seen a couple of other posts on XDA involving the same issue, but never saw a solution. I've even seen this issue a couple of times IRL (not on my device, thankfully) and have not been able to find a solution. The two times I've seen this issue, the backlight level could not be adjusted, either. Whether it was set to automatic or manual brightness, it would never adjust, the backlight was locked at a constant level, until the screen turned off, and then the backlight would NOT come on again until the tablet was restarted. Reflashing stock firmware and doing a factory reset did not help, either. On one of those devices, the backlight DID start working again for a while after a manual wipe of internal storage, but only until the tablet was restarted, and I think that might have been a coincidence, I was not able to replicate that again.
So in short, I'm afraid I don't have a good solution other than hardware repair/replacement via warranty.

this has just happened to mine - will have to send it into repair, but it had CLEAN ROM installed so they might argue re the Knox trigger - really annoyed about this!

Screen Not Turing On When In Sleep Mode

I've got a pretty major issue, and I've done a bit of research and it seems to be known but I can't find a solution to it. Basically, the screen won't turn on when it sleep mode, no matter how long I leave the device for, how long I press the button, how many times etc etc - so at the moment, if I want to use the phone, I have to hold power & volume up to force the phone to shut down and then turn it back on and not let it lock. If someone could help me fix this bug it would definitely be appreciated.
Cheers,

Do you have root or any mods installed on your phone? Stock firmware? What version? Maybe custom kernel? What governor and I/O
Wysłane z mojego D5503 przy użyciu Tapatalka

Phone rooted but xposed mods disabled.
Stock firmware 4.4.4
Build number: 14.4.A.0.157
Kernel version: 3.4.0-perf-gaee6e5a
Not sure how to find governor and I/O?

The few times I actually manage to get my screen on, if I hold the power button to shut down/restart, the screen just turns off, leading me to think it's a hardware issue (problem with the power button)? If anyone has encountered anything similar before or can think of a workaround, please let me know!

Pressing powerbutton screen goes on/off

Hi all,
I have some trouble with my Z1 compact. Very often when screen is off and pressing powerbutton (to get to unlock screen) the screen goes on but in the same sec goes it off. The same thing can also happen if screen is on and I want to turn it off -> it goes off and again on and I'm back at unlock screen. This issue appears kind of randomly and I have no idea if this is a software bug or a hardware problem.
Using CM11 M12 stable. Any ideas? Thank you

I have the same phone and OS, and have seen the same issue, but until I saw your post I have dismissed it as something I was doing when pressing the power button. I believe it must be a software bug, since I did not have the problem when running the stock OS. Perhaps it is worth a bug report.

I use Xposed and GEM Xperia Xposed module, that has 'wake up with volume keys'
Not really a solution, more of a workaround
