My O2 xda IIi's backlight not working after i've clean it! Help me??
I've not touch any IC neither Chip??
What happen with it??
By cleaning, do you mean a complete disassemble and rebuild? Or just an all over clean?
If you disassembled it then it's possible that you have assembled it incorrectly, I cannot remember if the Alpine has an inverter lead, or if it's built into the display connections, however if everything else works correctly, then the inverter is possibly damaged, or disconnected.
If you gave it an all over clean using some sort of cleaning fluids, then it may be that some of the fluid has found its way inside the casing, in that case you will need to find a disassembly guide, and carefully open your Alpine and give it a careful clean with a dilute detergent, rinse with water and dry out overnight ( or in a very low oven at about 60-90C, for an hour or two ). ONLY the circuit boards should be cleaned this way, the LCD screen should not be cleaned at all, other than a careful brush clean of the connector areas, using IPA ( IsoPropyl Alcohol ).
Good luck

Nice tip, one comment: beware of corrosion because of the water, sooner or later - if unlucky - it could cause the device to not function properly. My advice is after thorough cleaning, emerge all parts in ~100% alcohol (go to a pharmacy) as the displacement removes all water, while the alcohol can evaporate completely.

Does anybody knows how to rewrite the flash? I'm not talking about the rom. I spilled some water on the table and my camera is not working anymore, the SD-Card is not recognized and the phone won't vibrate. Plus it has some lag in the dialer app.
What do you mean with rewrite the flash? You at least should give it a bath in Isopropyl alcohol, but dont forget to dismount almost every removable part and to put some hot glue on the microphone, cause it gets destroyed otherwise, but google for isopropyl alcohol bath, or water damage alcohol, or something similar.
Here is one thread about it: http://www.fiscalgeek.com/2009/06/ff_water_damaged_cellphone/
And dont blame me, if you make any mistakes and screw your phone completely, but I already revived one phone like this.
The most important steps are remove diplay, put glue on the microphone, so no alcohol can come in and remove speaker (this also gets destroyed by alcohol otherwise), but read more how to's about it, and you will find the most frequent mistakes and so on
Dropped my phone in water.
thought everything was ok till I made a phone call and now the microphone doesn't work.
Any Ideas?
for anyone interested I opened it up to see how hard it may be. (i followed part of a youtube how to remove screen) found the board with the microphone on it, disconnected the ribbon cables and tried to pry it off lightly. It didn't want to let go. Figured I needed to use a heat-gun or blow-dryer with a plastic pry to get it off. As I didn't have the board I needed yet I decided to scratch a little on the microphone (probably did nothing). Popped the connecters back on and put it back together. turned it on and It started working.
May be it needed some air? May be the connectors were not engaging right? IDK but I'm confident I can replace the charging port and microphone on one of these because they are on the same board. The screen isn't that much harder either.
!
hi!
unfortunately i had the exact same experience but in my case the mic never fanctioned again.
Since you did it, can you please tell me which one is the mic...? is it the round thing on the oposite side of the speaker with the 2 spiral connections on it or am i ...scratching the wrong thing ??
thank you in advance man
A little while ago I broke my screen on my Sony Xperia z3 compact, so naturally I replaced the screen and the digitzer, and it worked (hurray!) for about five minutes (Boo!), after which the backlight stopped working, apparently this is a common issue and I managed to find a solution after googling "sony experia z3 compact backlight not working". Should be the first result (cant post outslde links as noobie)
So i attempted to make the jumper with a soldering Iron, but my soldering experience is clearly evidence of my ability to break phones as in the process I burned through the component I needed to make a jumper across (I think. though the whole mess is covered in Solder right now). And although the charging light comes on the phone it self will not turn on. It is completely dead, I have tried various resets but none work, I should mention the phone worked perfectly before hand it was just the backlight that was the problem..
Is it time to get a new phone, or is there still hope? I've already sunk over £100 into trying to repair the stubborn basterd but I've not quite given up hope
There's no issue if you simply covered the burnt fuse in solder (which is actually the same effect as what you'd do if you jumper it properly).
Try removing the solder as it might be shorting to other metallic components - such as a metal foil cap. Just put your soldering iron tip to the blob and swipe aside and lift.
Then on the remaining 2 solder pads, add a tiny bit of solder to join them.
Clean up the flux residue and such with some isopropyl alcohol (denatured or rubbing alcohol will work fine too).
Add a little sticky tape on top of the solder bridge to prevent any shorting.
Unplug the battery and leave to stand for a few minutes before plugging it back in and try to start the phone again.

Hey if you have given up hope then can I get yourEFS backup. My phone IMEI is bad after playing with roms and isnt getting fixed after numerous flash.
It is basically useless to me,
I can buy you beer I have a thread open for requesting but seems nobody cares
Hi All,
So I've had my Nexus 6 for about 2 years now, but recently had some weird issues with USB connections and I'm pretty stumped. The issue itself is that my phone will not be recognized by Windows, it doesn't even display in device manager. If I type 'adb devices' in cmd, then no devices show. I've tried using USB Charging Only, P2P and MTP usb options specified in the settings. However, when I connect my phone through the wall, it says "Charging over USB", now if I remember rightly it used to say "Charging over AC", I'm still using the official Motorola plug that came with the phone. I still have access to TWRP, but phone can't connect to phone through fastboot. Also, my PC is running Windows 10, just in case this is a known issue - although I've scoured google and couldn't find any answers.
One last detail, I first noticed this issue around the time that I moved from stock to Pure Nexus + Franco Kernel, think it was around the first release of 7.1.1. I've got a feeling this is entirely coincidental and unfortunate timing, but figure it's a detail I'll include just in case it is relevant.
So here's what I've tried so far:
Different USB cable
Different device (hudl2 was recognized by Windows)
Different ROM, didn't install FK this time
Different ROM with FK
Reinstalling official google USB drivers
So any suggestions as to what the issue itself is (dead charging port maybe? Although seems strange it'd charge at USB speeds still) and any suggested fixes?
Thanks in advance

Below suggestions about the USB-port:
1.
Cleaning USB contacts with air pressure or a small brush wetted with alcohol.
2.
Check the connection with Windows:
Use a different phone; different cable.
3.
Connect your phone to a different PC. When working you know that there's no hardware failure.

Brilliant suggestions, I'd tried cleaning with a toothpick already but not a brush, so went out, bought a toothbrush (couldn't find any alcohol) and after very little effort it started to work. Thank you so much, you have just saved me from buying a new phone

Isopropyl alcohol can be found at either Wal-mart or your local pharmacy for around $1.50 to $2.00 a bottle. Just be sure to use 89% or above, you don't want to lower as it would have too much water content, maybe even causing damage. 91% is very common in stores and alot of times the only option, I like to use 99% but you may have to hunt some down lol. Also very very soft toothbrushes are fine, but what I found works even better are the tiny, thin, very soft makeup brushes as you can fit the entire thing in the port allowing greater contact area when cleaning, also they are amazing for cleaning out the Nexus 6's speaker grills, they fit every nook and cranny, but most importantly, holding them at an extreme angle the bristles actually can fit up under the plastic guard of the speaker between it and the grill mesh without any worry of damaging it. Try it out and you would be amazed by just how much random debris get trapped between the guard and mesh. Just make sure if you are gonna "borrow" your girlfriends, wifes, or daughters brush, you clean it very very good with the isopropyl alcohol first, wouldn't want to give your phone a new, messy, smudgy, paint job lol. Also for the debris such as fuzz and dirt that are extremely packed down into the port, alot of times even shining a bright light, you cannot tell there is a layer of crud stopping your cable from inserting fully (I have cleaned some unbelievably disgusting phones people bring me over the years) I use a pair of ifixit's fine tip ESD safe tweezers and a lot of lighting along with a dab of patience lol. Just have to be careful, most importantly, not in a rush, and you can get it clean as day 1.
