bought my IIi for almost 1.5years and suddenly now suffers several problems;
- O2 Connect application gone after hard reset.
- AutoConfigure also gone.
- Touch screen alignment totally gone mad so i have to use buttons only.
just hope anyone here can kindly give me at least links for me to overcome the problems. till now i did not do any ROM upgrading yet. i searched this forum and found some info but it didn't help much.
thanks!

As you've already done a hard reset and so dont have any grat data to 'lose' by doing another), my suggestion would be to do another, by removing the main battery for at LEAST 1 hour to drain the backup battery also, so doing a 'true' factory reset. If your still happy with all the O2 stuff (I scrapped mine as soon as possible as it seemed to slow it down a fair bit) when you replace battery this should restore it from the auto-installer cabs you will have on your O2 extended ROM.

Whilst the device is off and draining the reserve battery, take a small piece of card and run it around all four edges of the touchscreen where it meets the casing. Sometimes a lot of crap can build up in there which inteferes with the touchscreen's ability to detect where the touch has been made, also take this opportunity to the screen with a screencleaner once this has been done (pretty much any will do, I use stock windowcleaner from the pound shop myself!)
Rom upgrading is easy once you have the required installer and some patience: a quick search for Alpine ROM upgrade should bring up plenty of posts, some by the authors of some of the modified rom packages themselves, explaining in detail the steps to take to upgrade the unit. It takes a little patience and in about half an hour you will have a PDA without all the extra stuff you don't need, that has (probably) an upgraded radio & camera (better signal strength, and pictures)
Hope this is of some help

Hello, Today I will show you how to replace a problematic sim/microsd/volume/power. The reason why they can be fixed together is because they are all on the same PCB that we will be replacing.
I made this guide because I went snowboarding and I dropped my phone in the snow. I tried the rice trick but after that my power button was still dying. I looked up prices for getting a professional to replace it and it was around $60 for a part that costs $10 MAX. So i just bought the part off of ebay and documented my process
EDIT: if the pictures don't show up, just right click and open in new tab for now
EDIT: There is now no need to remove the motherboard to solve this issue

https://www.dropbox.com/s/0u1yl88w08y5011/IMG_20140414_151702.jpg
New "easy" method
6) You DO NOT need to remove all the connectors, only the ones in red
https://www.dropbox.com/s/5cgxcq2ocm7fkwi/IMG_20140414_151844 - Copy.jpg
Take note that the electronic above the sim card slot just needs to be peeled off gently, It is NOT a connector but it does rest on top of the PCB.
Also, you'll need to pry off the vibration motor (the circle to the right of the Sim card slot) as it is glued in
7) This is what the PCB looks like when separated from the motherboard
Note: your motherboard will still be in your phone, i just wanted to shop you what both parts look like
https://www.dropbox.com/s/6ysyid9eu2v5jjw/IMG_20140414_152536.jpg
8) Get out your new PCB
https://www.dropbox.com/s/6130c74hcx...414_152619.jpg
If The PCB you ordered did not come with the shielding then follow these steps
Note: Your motherboard should still be in your phone
8.a) Remove the shielding from the back of the original PCB, be careful of the glue to not damage any components
https://www.dropbox.com/s/nfpuwzf3om1ib3s/IMG_20140414_152657.jpg
https://www.dropbox.com/s/73sbx0k32f4x5x4/IMG_20140414_152731.jpg
8.b) Now, put the shielding back onto the motherboard, it should fit into place nicely
https://www.dropbox.com/s/li966nnqujajgog/IMG_20140414_153037.jpg
8.c) Take out your new PCB and connect the connector to the motherboard before, placing it on the shielding
https://www.dropbox.com/s/mn97igyuir7o9q6/IMG_20140414_153154.jpg

https://www.dropbox.com/s/f3k5f1c7qelaq74/IMG_20140414_153420.jpg
9) Reconnect all of the connectors you previously disconnected EXCEPT the volume and power
https://www.dropbox.com/s/v0oyeoaswkd0gb9/IMG_20140414_153602.jpg
10) Now carefully slide in the power and volume buttons into their correct spots
(I used the flathead the push the rockers out of the way to slide in the buttons)
https://www.dropbox.com/s/l94dfverf2ziwl7/IMG_20140414_153832.jpg
Now test the feel of the buttons before putting the Screw back in. (You should hear the tactile feedback)
11) Screw in the screw you removed to get the motherboard out
https://www.dropbox.com/s/3dw6lf5rtqsslut/IMG_20140414_153856.jpg
12) Put the cover back on (do NOT put the screws back in yet) and see if the all the sides close properly

https://www.dropbox.com/s/69w769ubiz03fpk/IMG_20140414_154131.jpg
Time to backtrack and see what is not seated properly
14) After all that is done and is properly fitted, Put in your sim car, micro sd, and battery
(Do NOT put in the screws yet)
https://www.dropbox.com/s/it26v6h7763flzs/IMG_20140414_154143.jpg
15) Now power on and see if it works
https://www.dropbox.com/s/fumzxsuewnqqgn4/IMG_20140414_154158.jpg
(Mine did, I was so happy I could cry!)
16) After it power on, test all your buttons
17)Test Cases:
Press power button once to see if the screen turns off
Press the power button to see if the Screen wakes up
Press the volume up to see if the volume increases
Press the volume down to see if the volume decreases
Check your sim connectivity, should have bars
Check your micro sd card by going to Setting>Storage>SD Card
Check your cameras
check your sound
If something does not work, backtrack and check all of your connections.
If your power or volume buttons don't work, check the PCB connection. If it still doesn't work, you might have received a defective PCB like I did (My volume buttons didn't work). Contact your seller and ask for a replacement for your defective item (I got mine for free and now everything works).
18) If everything works, NOW screw in your remaining screws and close her up and enjoy your day!

vibration motor?
hi i have been following your instructions and everything has been going very smoothly. however, i cant figure out how you take out the vibration motor from the old pcb and put it into the new one. do you simply yank it out? i dont want to break anything, thanks!

No do not yank it, the wires are sensitive, I used a soldering iron and heated the contacts up enough to the point where the wires were able to be pulled out. Then I soldered it to my new one. (Remember which wire goes to which contact)

Its honestly really easy and a good skill to learn, but there are PCBs with the motor already attached on eBay if you ever need it.

Awesome walkthrough.
I might use it one of these days as my power button is pretty much gone.
Thank you. I'm having weird SIM card reading issues. Flash the same ROM twice, and once it will detect the SIM, the other time it won't.

That doesn't mean anything is broken.
Try flashing a stock ROM and if it works then your sim tray is still working

Don't forget to hit thanks!
So if I flash SlimKat 8.9 which I know the SIM card would read on before, and now it doesn't that doesn't mean it's a hardware thing?
Also, no custom ROM will now read the SIM. I've tried probably 5 since it started not reading. I'll try the stock ROM before I tear into it, I guess, but it seemed logical to me. IDK.
Radio is extremely crappy on this device. Custom roms don't implement all stock radio features so there can be (even randomly) broken things.
Hmm. Well, I tried to go back to stock. It just won't. Even got to a point where the LG update tool would flash in and out of being connected to the phone, and it would never settle on one or the other, so it can't do anything. Flash tool also reports no connection to the phone no matter what I do. I'm just about sick of this thing.

Probably a silly question but have you tried a different SIM card in the reader to see if it could be the SIM card itself that is a problem?

I agree that soldering is indeed a useful skill but I am not sure that a relatively expensive (and I am sure in everyone's eyes, precious) phone is the best place to start practicing; heat damage from a soldering iron can do irreversible damage to sensitive components as well as the copper tracks on the PCB.
Also, I may be a good idea to edit the guide a little to mention the possibility of needing to desolder/solder if the appropriate parts require it?
Yes, tried multiple SIM cards. None work on a custom ROM now. My first flash with SlimKat 8.9, was golden in every way but the camera. Then nothing but trouble with everything else. Even the "stable" CM 10 wasn't stable for me. I just managed to get a pure LG 20d ROM installed, and everything works fine. Battery life is even great. I started flashing custom ROMs to get a better device, but now with a rooted, Xposed, and stable stock ROM, I kind of wonder if it's worth bothering. It would be nice to have KK, but I don't really miss it TBH. I still have root, I still have "most" of what I liked about KK, and there are no more bugs.
Same with my original Nexus 7. Both had been flashed to KK of one sort or another (MANY times before I gave up), and both developed issues from it no matter how I did it. Went back to stock JB on both devices, and everything is fine.
If I flash any more custom ROMs I'm def going to keep a solid JB backup ready to get a stable device back if need be, and so far need be indeed.
Hello,
My LG Phone on KK stopped reading my SIMs a month or so back. I tried different SIMS, but still wont work. I flashed KK again and then later Lollipop AOSP, but still wont work. I thought maybe the SIM Reader was faulty, so ordered a new one. But even after changing, same problem. Don't know what the issue is. Can anyone suggest any further solutions / ideas ? Thanks.

If I want to repair only power only button that has became defective and doesn't respond well I have to do all these steps?? OMG
Is this the right component to purchase to fix power switch? (see attachment)
I couldn't find anything close to what I was looking for though I could be using the wrong terms. I was repairing two Droid 4's to use, I had them both working but realized that when they would get bumped (even lightly) it would cause them to shut off. I removed the battery and realized that one of the contacts where the flex cable gets screwed into the phone is not attached to the phone anymore. I'm including pictures to make sure everyone knows what I'm talking about. I'm hoping that this is definitely the issue and not in addition to something else but until I fix this part I won't know.
I want to reattached the part but soldering is not an option. I was thinking conductive glue but I wanted to make sure that it would be appropriate to use for this purpose. Thoughts? Thank you in advance!
Probably too late, but...
Just using straight superglue might work.
I'm 90% sure the posts are grounds and therefore needed, but you should only need one. Easiest way to check would be to screw the battery ribbon to the still-attached post, then apply pressure to the missing post side so the +/- pins make contact. If you get power and the battery reads fine, you can probably get away with just one side conductivity attached (as they're probably a common ground anyway). Slap some superglue on, reattach the post, done.
If not...well, then it'd be solder or as you say, some kind of conductive glue.
Hello Everyone,
I have been unable to find this information anywhere so I thought if anyone knows this would be a good spot for it. So a quick back story, my turbo took a dip in a hot tub for about 5 minutes. I put it in rice as quick as I could (about an hour) long story short it was completely dead unresponsive. I ended up doing a bunch of research and buying an ultrasonic cleaner, taking it apart and cleaning it soaking in 99% isopropyl. I did that several times and each time more functionality returned. At this point everything works perfectly other than wifi and bluetooth (presumably on the same chip). They are both permanently grayed out and cannot be turned on. I would like to know where physically the problem is before attempting anything further.
So can anyone point out the wifi, bluetooth and antenna for each on these pictures? I tried to post in pictures but it seems I cannot because I am a new user. I think you can copy and paste these into browser though or maybe someone else can post one in for reference. The first image is the back of the screen as well as the little cover that goes over the battery. The second is the motherboard.

Oh and while Im at it does anyone think there could be a software issue resulting from water damage like would I need to reflash some drivers or something?
All help is greatly appreciated!
Im going to try contacting motorola and ill update post if I have any luck
You should try flashing the software using rsd and doing a factory reset! Doubt Motorola will be of any help cuz u void the warranty when u take open ur phone and I don't think water damage comes under warranty!
Are you sure there is reason to believe this could be software related? I just finished rooting and getting everything set up, itd be a shame to start over.
Motorola was no help of course said its top secret. Is there no one out there with the electrical engineering or phone repair background to tell where the chip is from those pictures?
Nobody will know from those pictures - all of the IC's are hidden under the metal shields. Your best bet is to check out the FCC filing pictures of the phone, there should be some with the shields removed. If you can read any of the #'s start googling them.
Or find someone else who has taken high-res pictures with the shields removed, chances are they are out there.
This ways is for:
- When you connect the watch to the charger, it's turn on and says charging but when removing it from charger it's go black (auto poweroff)
- When you press the power button it's won't boot or go black (auto poweroff) at the "LG" screen
You need:
- Old battery
- Soldering Iron and Soldering Wire
Optional:
- 0 ohm resistance
1.Remove the sticker and plastic case on the battery protection board
Image see attachment files 1
2.Use Soldering Iron to remove the component in the image
3.Soldering 0 ohm resistance to the position of removed component or just use Soldering Wire to connect two contactor, it should be like this:

Can someone explain what is going on here exactly? Is modifying this resistor going to make my watch potentially unsafe (eg. overcharging)? I find it really interesting that my replacement battery had the same problem as the original.

This may be a battery manufacturer's problem,the old "component" are broken. Just don't use charger(dock) output > 5V 1A there will not safe problem.
Excellent :good::good:
I was having this problem even after changing the new battery, I used above fix and now its working perfectly since yesterday. Thanks Again.
Hi,
I have the same issue since a few days. First of thanks for the provided solution. But because removing a potential fuse and bride the contacts doesn't sound really save to me, I want to ask if someone who has done it month ago can report that there are no issues so far.
And if someone had issues please report them, it would be much appreciated and help other people too who will find this Thread in the future.
I just wanted to say thank you!
I bridged the component with a blob of solder and half expected it to blow up in my face but it works just fine. I think I'm gonna order a new battery anyway since this one is 4 years old but this fix solved it for me!

Thank you!
Worked like a charm.
my 5 year old LG G Watch R is alive again.
Gonna order a new battery soon tho but this really did the trick

Hi can u share the link for the 8 euro battery. Can't seem to find one nowadays
I can confirm the fix works as charm!
I really want to thank you for this amazing trick! My only hope is that whatever the piece we removed was, we don't end up with an exploding battery on our wrists! ?
Here is a Link .
It's on eBay Germany.
Between it's now for 15.99€

Thank you for this instructions, i was able to fix my g watch r and get it back to working. I didn't use it for quite a while, and when i wanted to use it again it started to only work when charging (similar to my lg g3 when the battery is almost dead, which i fix with a new one, second replacement).
And i decided to give this a try before buying a new battery, my thought was that i had nothing to lose... First attempt aasn't perfect, i was able to remove that little chip, but the soldering didn't went very well (i am not very talented with a sodering iron) and when i reassembled the watch it started to flash a empty battery icon and didn't charged or turned on.
So i tryed a second time and the sordering ended up much better the second time. The 2 connectors ended well connected this time and it is now working normally.
It was very helpfull and it worked much better than i expected.
