Hi Everyone,
After doing a deep search i did not find the exact problem I have.
Specs:
Phone: SGS2 i9100
ROM: CM10 Nightly 08.09.2012
Kernal: CM Stock
You can see the symptoms of my problem in the video I found below (it wont allow me to paste link with less than 10 posts so i shortened the URL)
youtube.com/watch?v=BCyp1iCTW2M
This is what happened:
1. I had an Adapter from Car Outlet to USB so i connected my phone using it but it seemed they did not like each other.
The phone was stuck on a black screen so I restarted it and noticed I lost 40% battery in those few minutes, looking at BBS i saw the RIL wakelock so decided its just a coincidence and i'll let the battery drain all the way to calibrate it at night (the phone worked perfectly fine)
2. After the battery was fully drained I connected it to the PC to charge and turned it on and everything was fine, noticed it was at 0% so after a few minutes it turned off, after doing it a couple of times i let the phone charge "turned off" (thought maybe its low voltage of PC charge) through the whole night
3. at morning it did not charge at all, I managed to "almost" turn the device on but now the battery is really drained so i cant even do that
4. when i tried going into download mode (just to see if my phone is OK) i managed, when i am trying now i get "Battey is to low, cannot download"
5. I cant get into recovery mode, but i tried it after all the process above so its probably because of low battery
6. I tried it on 2 diffrent batteries (unfortunately my old one was also drained before)
- Anker 1900
- Original Samsung 1650
I am going to get an AC charged and try using it.
Any Ideas what should i do or what the problem is ?
Thanks in advance!

This is the way to go. First make absolutely sure the battery is charged, if possible by testing it in another device. With a fully charged battery it should be possible to find out if your phones hardware is still fine, especially the charging board.

Hi,
Thanks for the reply!
So far i got an AC charger for the phone (not a battery only cradle charger kind of thing) but getting the same problem.. it just wont charge the battery through the phone..
I'll try to get a fully charged battery to give feedback that the phone is fine and not bricked in any way as i mentioned before.
If everything is fine i'll see that the battery is chargeable when not completely dry and we'll be smarter after that.
in case it really became unchargeable and it is a problem in the charging board as you mentioned
Could you please expand on the functionality of the charging board ? and whats the process for fixing/replacing it ?
Thanks in advance!

Excellent! If it is not bricked then chances are good that it is 'only' a battery/charging problem.

If, in the end, the phone does not charge by the USB connector (no matter if from PC or wall plug) then it could be worth to replace the flex print with the USB connector and parts of the charging electronics. This flex print is quite cheap and you can get it from ebay. With the help of some video from youtube you should be able to replace it yourself
Well,
I have an update on the issue.. unfortunately can't say its a good one..
I've tried turning on the device with a diffrent battery (charged) and it workes perfectely fine.
since I live far i didnt want to wait a month till i get the USB flex from ebay i went to a repair lab and let the test the phone.
Unfortunately it is not the USB Flex but a deeper problem,
apparently the u500,u501,u504 parts got fried on the MB and they don't have them at all.
I am going to try to restore my phone (using a full battery) to the way i bought it and try go to the store and work the warranty (it voids as soon as i changed ROM), going to have to read a lot on how to do it perfectly and erasing traces of changes (go an old nand and need to unroot afterwards)
do u know a good guide for restoring the phone to full stock ?
Also,
is it possible to buy a complete MotherBoard for the GS2 or its not worth it ?
Thanks for the help!

There are quite a few guides around here that deal with unrooting and getting the device ready for official service. Personally I just make sure the flash counter is reset (TriangleAway or JIG) and then flash a stock firmware.

You might find one on ebay but I think replacing the MBO is not that easy, even though never did it myself.

I had the device opened several times. Replacing the MBO should not be too difficult. There are only some screws and connectors.

If the warranty wont work than I saw its around 150$ but if that will solve it it might be worth it instead of buying a new phone.
Thanks Again!
They are a lot more than that unless you are in USA/Canada.Theres a firm on eBay that give you $30-$50 for your old board,and they sell theirs for around $180.
Samsung would be around $250...

So.. After a long time (!!) I have an update.
No lab fixed my phone as everyone said its "unfixable" or need to replace some parts that they don't have... so I did what I planned to do.
I took a full battery from a friend
Restored the phone to full stock (the same official "partner" ROM I got the phone when bought it (even putted Android 2.3 on it LOL)
formatted my SD card , and of course did a "Triangle Away" to reset the flash counter
basically returned the phone to the way i bought it..
Since I still had around 2 month on the warranty I went to the store i bought the phone from and they accepted the phone based on warranty, as i didn't install any ROM's (LOL )
Only TODAY after more than a month and a half of wait, while it was at their official lab, after that was sent abroad to the Vendor itself, after nobody was able to fix it I got a new phone (14 days used phone) so, considering i was ready to throw my phone and by a new one it turned out OK.
since no one was able to fix it, it was probably a major problem.
Of course its better i got a new one, since even if they fixed the issue, who know what else it might effected so its a very good result.
Don't know if this helps anyone a lot, but at least its some closure to the thread.
Thanks for everyone who helped here!
Out of the blue, phone went dead. I dont know why really. It honestly didnt get any moisture, or bad current, I never charged it via USB. I have drained it couple of times to zero battery but it charged after that. this time, it was at 22% wen I went to sleep, in the morning it was dead.
I know that this issue always resolves with: "use warranty" suggestions but I tried, and being that I live in a weird country that wont happen. Generic answers like "water damage" with the sticker still white and all that.
ADB doesnt see the phone, also.
anything anyone has to suggest other than telling me phone is dead (obvious) and to use warranty (which I cant) .. ? Please help, this is my first LG and maybe there is a solution that works
Have you tried :
hard reset - turn off your phone, press and hold Vol-, the home key, and the power for 8 seconds.
or
fastboot http://forum.xda-developers.com/showthread.php?t=2119090
Will try it in the morning (6-7 hours) as I hafe dissasembled and analzed the whole device internaly for possible rust or theoretical moisture from cold weather. Found None. Really hope this device isnt one of those that just die for no reason
battery might have gone dead. get it charged externally for few minutes and then try charging with phone. if it works for first time, then its time to change battery.
well, this is just a possibility.
for all you people, if you ever get in same situation:
Phone was moisture damaged. I didnt get it wet, but there are 2 possibilities:
1. a friend told me that all the shipped phones, compared to the air cargo phones, get damaged no matter how good protection is. If they are shipped to your country from the land of origin, they are most probably water damaged already. Being that I live in Serbia, and all the importers of goods use ships instead of air cargo (big price difference), my phone may be water damaged before ever turned on.
2. it was a ridiculous weather in Belgrade, with minus temperatures in March, so a simple condensation may have damaged the phone.
SOLUTION:
Service shops CAN repair the phone if it was moisture damaged instead of immersed, because air moisture damages only certain electrical circuits, instead of the whole board. My phone is at a service shop now, and the guy is inspecting the damaged circuit. It can be restored, and if the damage is high it would require replacement of the circuit which is kinda tricky cause it requires very similar board like the one LG L9 has, for harvesting.
If anyone maybe somehow finds a working SIM free motherboard for LG L9, please let me know cause I cant find it online. Just one ebay entry with "works but has issue" which I wont buy.

LG Optimus L9 P769 is not charging
My LG Optimus L9 P769 is not charging. I have used the same charger on other phones and it works. I removed the battery and charged it on an external charger and the phone works normally other than not charging.
I have done a hard reset after turning off the phone and pressing and holding Vol-, the home key, and the power for 8 seconds but that did not help!
As a last resort, I also replaced the Flex Cable Charging Port and Flex Cable Dock Connector using the part on the attached image but the phone still does not charge.
Can anyone suggest what I may do next to repair the phone? Any help would be greatly appreciated!

Hi,
today my I9100 froze while in the browser. It didn't respond to any touch or button activity. So I removed the battery and reinserted it, but the phone didn't boot up. There was nothing, a black screen, no matter which buttons I pressed.
I tried the Download Mode, Pushing the Volume-Up/Down while plugging in the USB cable. The battery is fine, I tested it on another phone.
The phone was rooted with cm-10.1-20130606-NIGHTLY-i9100. It does not matter if a SIM is placed or not, still no response from the phone.
One odd thing tough: The phone gets warm in the right corner, near the flashlight when the battery is inserted for a while.
Can I do something or is it dead?
Replace motherboard; service centre - new motherboard (most expensive option), source 2nd hand motherboard from 'donor' phone (with a broken screen, etc; search online) & either replace it yourself or pay a local mobile repair shop to do it (cheaper option).
And if your warranty is good, you could always take it to a service centre & play dumb (obviously they're under no obligation to repair or replace it under warranty tho given you've voided it).

Wouldn't it be have to repaired in order to determine if a custom ROM was used? The phone is not showing any reaction at all, so I guess the only way finding out is reading the flash chip itself, is that possible or is this the normal case?
Anyway I purchased a USB JIG, just to be sure before I give it into repairs.
They might be able to tell. You might get warranty service. These things are never guaranteed either way. Take it to a service centre & find out.
Edit - Jig has 0.00000001% chance of working, but try it anyways. Heat around camera & no life = dead components on MB.
Similar or probably the same issue

My phone is a I9100, rooted, running CM 10.1 Nightly (I don't remember which exact version but definitely not the latest nightly). My phone was in my backpack along with my laptop. When I tried to use it, it remained unresponsive so I turned it off by holding the power button and then turned it on again. It showed the "Samsung Galaxy SII" boot logo and was stuck.
So I pulled the battery out, waited for about 15 secs, put the battery back in and turned it on - no reaction. The phone won't turn on, my computer doesn't detect, not charging. The service center says that my Mobo needs to be replaced.
I have ordered an USB Jig but I'm not sure if it will work. Did you try the Jig? Did it work?
My phone does get heated up near the rear camera even before it died. So not sure if it really is a fried mobo and bootloader failure.
If a service centre has told you its a dead MB, a jig ain't working. Save your time & have it repaired now.

He could maybe try the jig 6 times a day for 6 months to see.
He either didnt read your earlier post or doesnt want to accept reality.

Got the motherboard replaced and phone back to usage. Thanks!
I was driving and my phone was in my pocket. There is no way it was hit or got wet, I was driving whole time. Next time I took my phone, it was off. I tried to press power button and also hold it, nothing happened. I though my phone was stuck (never did it before) so I pulled out my battery, waited 10 minutes, put it back in and tried again. Nothing. I also had charger in my car and tried with that, nothing happened. No LED light, no screenlight, no vibration, nothing.
Now few hours after I am home and started to check whats wrong with my phone. I tried with original charger, nothing. My girlfriend also has S3 so I tried with her battery, nothing. She put my battery into her phone and noticed that it didn't go on. Funny thing is that I took my phone off charge this morning and phone was on for maybe 4 hours before this "death" happened. I took my multimeter and checked voltage. It was 0. Not 0.4 or 2.1 but 0.000. I checked my girlfriends battery also if my meter was broken but I got normal value from her battery. I plugged my charger into my phone and left it for 15 minutes. I tried to check voltage again and it was still 0.
Question is, did my MB broke and created short circuit resulting emptying my battery completely or did my battery flip and broke my phone at the same time? Also, are both cases under normal warranty and will Samsung still repair/replace my phone even if I had it rooted and installed MIUI? Reason I ask this is that my phone won't be sent to samsung for nothing and that they won't ask me to pay for shipping and investigating problem (I don't even want to know their hour wages for this).

Broken motherboard suggests physical damage = no warranty.
Rooted and custom rom = no warranty
Will Samsung see its been rooted ??
Boots to download mode ??

But funny thing is that my phone didn't take any physical damage, it has never falled from big height (maybe something like 10-20cm and always to soft surface like carpet). It was working when I put it into my pocket and was broken when I took it. I was in the car whole time, not moving from drivers seat.
I'm not sure if Samsung will see if it is rooted since phone doesn't boot at all (tried with working battery). No vibration, no LED light, no screenlight. It's like trying without battery.
Do you think I should try and send it to Samsung or just throw it to trashcan?
If the motherboard is DOA then they won't try to fix it, just replace it and your battery (if the battery is under six months old). Well worth sending for warranty, at worse you'll pay the postage and refuse the repair if they try to charge you.
send it in, only option
Agree suck it and see .

My phone and battery are over 1 year old so no warranty for my battery. I just though maybe problem is at on/off switch but then again it doesn't explain my empty battery. I am now charging my battery on my girlfriends S3 and seems like it is charging so I guess problem is on my phone only. I will take my phone to local shop and they will send it tomorrow to Samsung. Thank you all for fast answer, lets hope best that they will switch whole motherboard and wont notice rooted phone.

Hello,
I am experiencing the same issue as well with my phone. I have left it on charge overnight and the phone stopped working. I have tried all the steps above but without any luck. If I take the phone for repair as you advise, are there any charges involved? And if they are, how much is the average cost for me to be ready for it and avoid getting a heart attack.
Thank you in advance for any replies.
If covered by warranty then there should be no charge, SDS is due to Samsung problem.
But if warranty is not available then allow £200 for a new motherboard.

Well with the situation that I have with the phone at the moment, is it even possible to detect the root?
If the motherboard is completely dead then no, they won't find root (root alone doesn't invalidate warranty in the EU). The only problem might be if JTAG restores bootloader and flashed counter.

Well my poor S3 is under repair at the moment...
I was given an s4 by a friend today. It's hard bricked. NO download mode, NO recovery, NO response of any kind.... Other than Jtag is there a way I can fix this myself? Odd thing is the phone just died while out and about, and now nothing. No response of any kind, not from a wall charger, car charger, usb to wall charger... Zilch.
Is there any way I can at least get this into download mode? I know I can fix it from there, but I need some sign of life.
--Bought a brand new battery and that changed nothing. Still the same situation

Jtag is your only option. I have the equipment but have never had to use it (mine was hard bricked but my warranty company finally agreed to replace it). I'd be happy to try but there are other people out there that have jtag service and have done it before. The battery finally gave out. When hard bricked, the battery will not charge or even get warm.
