Help Please - D800 Logic Board gone the way of the Titanic - G2 Q&A, Help & Troubleshooting

Hey all. Have an LG G2 D800 that I got the Watchdog Bark then a Watchdog Bite and then my logic (motherboard) board went the way of the Titanic. I have replaced the logic board but there are some pictures on the old logic board that I need recovered. I tried all the solutions offered here to get the logic board recognized so that I can reformat/recover the disk and reload the system to no avail. As such, I went and bought a used logic board. Phone boots and goes into the system fine and operates great except that I have no microphone pick up whatsoever. So I replaced the charging slot/speaker/microphone board with a new board and still no microphone pickup but the speakers work fine as does the charger. This indicated to me that the "new" logic board that I got has a problem, but I am unable to resolve it even using all the tactics that are specified here on this and other forums.
Anyways, the old logic board is out of the phone and I am willing to compensate someone if they can retrieve the pictures off of this logic board for me. Again, I tried everything to get the board operational including shorting the capacitors but nothing seems to work. I am just a regular person with very very limited knowledge of this stuff so any help in resolving this problem is going to be greatly appreciated. The computer only tells me that the "USB Device Unrecognized" and no drivers load so I can not use the LG Flash tools to fix it, and I also tried UBUNTU but this OS did not see the logic board either.
And any other recommendations on how to solve the microphone issue on the "new" logic board is welcomed as well but I have gone through about 100 different threads on all sorts of forums with no solution to this problem, hence this is why I think the "new" logic board is bad.
Any advice and help appreciated.

mapping hardware for this device

Hi all,
As i started servicing all pdas for a couple of monthes (only as a hobby, i fix them for friends and relatives), i came across one BA that gave me some trouble.
i got it to replace its LCD that was broken as it was dropped and thats very simple to replace it, so far so good. now it has two main problems :
1. no sound from speaker (even when in speakerphone mode), but there is sound in the stereo earphones (i plugged to the connector by the sd card slot). - i can only assume that a bluetooth handsfree device it will also work.
2. although the backup battery is fully charged, if i remove the main battery even for a brief second, when turned on, the BA acts as if i made a hard reset.
as for solving the problems :
1. using a digital multimeter, i managed to track the conductivity from the internal speaker through its connector, flat ribbon to the connector which connects to the main pcb - so there is no contact problem from the speaker to the main pcb.
using the help from WIKI, i went to site that has the list of all components and their description - the IC that is responsible for audio amp is a MAXIM's MAX4410 which is a stereo headphone driver. a quick look at its charasteristics and typical configuration and i understood that (assuming this is the IC that drives the internal speaker) the speaker should have one pin which is ground and the other goes to the amplified signal from the IC. neither one of the pins showed it has GND to it. so maybe there is a bad GND line to the connector.
2. regarding the backup battery issue i do not know what makes this problem.
I am sharing this info with you all with two ideas in mind :
1. to resolve my problem and know those devices hardware better.
2. because i am quite a while watching xda-developers and WIKI and i got the feeling that a lot of eforth is given to the software side of all those pdas (which is greate!!! keep going, this work helps lots of people and it shows al thos mega corps they are not the only ones), but the hardware is a bit forgotten and left behind. let me tell you this, there are many VERY simple mini projects i made useing electronics (i am an electronics engineer in my profession) that made my life easy . i am now investigating those instruments hardware as i have several ideas to develope useful accessories to my pda (like an external IR transciver to control IR devices like TV,DVD and to communicate with my laptop, and some other ideas) and i believe we can do the same info sharing as done on software side but on the hardware side.
I will thank any ideas, thoghts or commentsabout this matter. Yol.
I think you should post this again, just in case we missed the other 9 duplicate posts... wouldn't this have made most sense in the development and hacking section, pretty much the only section you didn't post to?

@Vj LOL
Fault 1) When I hear someone saying 'maybe it has a bad earth' i think of car mechanics 'wiring' and Ford cars! If you have the data sheet, use a 'scope - fixing it should be a piece of cake (IF you know what you are doing)
Fault 2) These devices usually have tiny 3V Li-ion button batteries somewhere inside - find it, replace it.
BTW - search the internet for a SERVICE MANUAL - you NEVER know your luck!
Andy
Fault one the backup battery is designed to keep memory alive not power the unit! I would expect it to act the way you describe.
Audio check the stereo jack, my guess is you'll find the problem there. It's rather common failure.
I never said the battery backup powered the unit, did I? He said removing the main battery & putting it back in acts like a hard reset indicative of a knackered memory backup battery.
I'm making educated guesses based on 15 years experience as an electronics engineer & also that I have just fixed an Xda Exec with EXACTLY this problem (If I'm reading his post correctly that is).

mini ubs port has gone a bit awol

i need help!
first off i am the most untechnical peron ever so rather sucky at all this, second i can't afford the excessive repair charges and thirdly i hsve an o2 Xda Mini.
basicly the ubs port socket thingie has gone completely wonky and turned it's self around within the phone. i have searched about the place and i can't find anything that i can understand or helps fix the problem.
basicly is there anyway i can open the phone up myself (i've had a look at the phone and there's no obvious way to get it apart) and put the little socket back into place..because it has gone completely wonky. i think it happened after i dropped the phone on the floor (by accident) and now it won't work with the charger.
any help would be brilliant.
thank you
Amy
If it is turned around within the phone you most likely broke the contacts with the mainboard, you are pretty much S.O.L. However I think Isaw earlier that some forum member can do it. I'd check into that.
Yea - it is probably broken off the main board, but you can open it up and see what is going on if you are inclined to do so.
Service Manual
You will find detailed instructions and pictures on how to open the phone up. The only difference I think in the manual and this phone is the manual does not mention a screw on the main board. When it talks about removing the main board and getting at the rigid-flex board (page 20), it does not mention anything about a screw in the middle of the main board. It's there - that board isn't going anywhere until it is unscrewed. However, you probably won't need to bother with taking the main board out - you just need to get to where you can see the main board since you just want to see the USB spot.

Phew, My Shift is Back to Life: Thank God !

After frying my Shift motherboard sometimes last year I had given up any hope of ever getting it to work again. ( http://forum.xda-developers.com/showthread.php?t=701950 ). I tried HTC support to have the motherboard repaired or even to be supplied with a new motherboard without any success. Tried any relevant outlet I could think of that could source a motherboard but still nothing came of it.
I tried searching for anyone selling a Shift at the cheap but the few ebay listings I came across showed that the device cost is still very high. I started a link here hoping somebody with a dead Shift could sell it to me for spares but nothing came of it. To make matters worse the thread was moved to Xda Marketplace and it was lost and burried in the market. ( http://forum.xda-developers.com/showthread.php?t=937322&highlight=shift+motherboard )
But as fate would have it the other day I searched the Marketplace and came across a guy who was selling 2 dead Shifts and high capacity Shift accesories and spares including 2 Gb Ram stick, SSD and higher capacity batteries. But I was a bit late to the party! The sale had been on for almost 2 months and most of the valuable items had already been sold. But I was still in luck as the dead Shifts were still available. I bought one of them as the other was a complete shell even though the motherboards had problem as the power switches had detached and gotten lost for the both of them.
Fortunately an electrical engineer friend of mine was able to remove the power switch from my dead Shift and solder it to the purchased motherboard. It was a delicate procedure but I can confirm that all went well and my Shift is now back to life. Infact even with the replacement motherboard my Shift booted with all the data and settings exactly the way it was before roasting the motherboard.
Just thought of sharing my experience with fellow proud Shift owners here.
I would also wish to thank the seller (TopRowGuy) for a very swift and smooth transaction. Thumbs up buddy. ( http://forum.xda-developers.com/showthread.php?t=961663&highlight=shift+clio )

Hi Ed, congratulations for resurrecting your Shift and thank you for posting here the info.
While having the spare Shift and old motherboard at the hand, would you please be so kind to have a look at the circuitry of the socket for external headphones&microphone. My interest is related to the non-working condition of the Shift phone on external headphones&microphone with the custom ROMs.
Therefore could you please check if the socket is simply switching mechanically between internal speakers and external headphones, respectively internal microphone and external microphone (just like in any other audio-tape device) or other circuitry is also involved invalidating the phone function when external devices connected. What else gets disconnected when plugging-in that is influencing the phone? Can the microphone switch be overridden to use only the internal one permanently and let only the headphones be switched?
I'm pretty sure that there are many members here interested in your answers to the above questions. So thank you for contributing to this community!

Thank you Axel.
Ok I will check the switching mechanism for the mic+headphones for the Shift and report back. If relevant I will also take close-up photos with both the the jack plugged in and plugged out. Since I have the extra motherboards boards (both winmo and Vista) I will try severall things. But if i am not wrong the headphone jack is actually attached to the windows mobile motherboard and not the windows vista motherboard....
I will do the necessary and report back. Of course I am also very much interested in finding a solution for the century old problem of non-working external mic phone side..... I will also snoop around the Memory Card Reader and see what gives ......
Thanks Ed!
My idea is that we all might get lucky if the phone would work on external headphones (i.e. have some privacy), but with the internal microphone (you have to speak-up loud anyway).
I expect that, just like in any classical audio set, the switching circuitry on the audio out side gets the signal out of an audio stereo IC, which is led further to the ext phones socket and involves nothing more than the connection wires, socket, loudspeakers and earphones. If so, that means that we are OK on the earphones side. Of course this is an assumption and means that there are no active speakers or anything of the kind linking the audio outputy to any input of the mciroprocessor.
I also looked at 4 contacts 3.15mm coax plug of the HTC earphones and microphone and the contacts for the limitation comes from the microphone circuitry, this can be arranged by disconnecting the internal microphone from the ext socket and leaving it connected all the time.
My guess is that the internal microphone is hardwired directly to the socket and is not going trough the motherboard PCB (printed circuit board), in which case can be desoldered from the socket and resoldered to the audio in signal path (also coming from the socket). With this mod inserting the plug will have no influence any more on the microphone path.
In reality things can be more complicated since the same ext socket is serving both WinMob side and Vista side. I wonder if there is a single audio out IC or just the two processors deliver in paralel to the same load (speakers).
Looking forward to your findings.
Axel,
I had a long and hard look at the mic and audio jack/port and I am afraid there is nothing much to gain from a physical examinations of those items. To start with the audio port is covered with a black plastic on the outside so you cant really see what is going on inside when you insert the jack.
The audio port is connected to the phone mobo and not the Vista mobo. The phone motherboard is not spoilt and hence I would not want to strip things from it as it can come in handy at a future date. The internal mic is also attached to the phone motherboard through a printed cable. Problem is without first booting the Vista Bios the phone side does also not boot. I am trying to see if there is a way I might get the phone side to boot. If I can succeed that way I would then disconnect the mic from the phone motherboard and see whether the wired mic can become active as you have suggested.
But all this I am only doing with the dead Shift because of course I cant touch the recently resurrected Shift. I wonder if there is absolutely any way of being able to boot the winmo side without first pressing the power button (attached to Vista mobo) which is missing from the motherboard that I am playing with??? If that was to be possible I could try various things with the mobile powered on and probably even be able to use the mobile side ad forget about Vista on the cannibalized Shift?
Here are some photos of the audio jack port and the mic connection area. Sorry the images are not great as i took them at night and in low light environment.... These are self-explanatory but the long and short of it as per your inquiry is that it is possible to disconnect the internal mic from the motherboard. As to how the wired mic would behave when the internal mic is disconnected is subject to real tests with a working Shift. As to whether you can solder these around I will leave that to those of us who are more technically oriented.......

Hi Ed
I'd read your post. Also, I have som problem about my Shift
the conditions are:
1. it can not be turn on even vista or snapvue
2. When I switch on the power button, only the green light was on at the bottom of LCD screen.
3. I can hear the fan turn on but nothing happened
4. When I use the charger, the battery can be charged and finished it.
Do you think that the mother board have something wrong?
The HTC care center want me to change the board but it cost a lots.
Regards,
Vincent

If the green light is turning on I think yours is a software problem. What about the mobile side? Does it come on when you press the button for switching between the Snapvue and Vista? Try that with the green light on and then we can try troubleshooting from there.....
In the meantime try press FN+F10 immediately the green light comes on and see what happens.....

Hi Ed, thank you very much for your endeavour. Of course I didn't expect to work in this experiment with the ressurected Shift, but only with the spare one.
What kind of a switch is the power switch, is it a single section switch or with multiple sections, is it a bistable or a tip-switch. I expect that it is a single section tip switch which is connecting 2 contacts on the pcb only for a short while while you press on it. If this is correct you may connect the 2 contacts with a jumper-wire just to start-up the Shift. It is true that the Vista part will start first, but I don't see a big draw back in that.

Thanks again for the pictures, maybe some other time you'll have the opportunity to come up with more clear ones.
To get some privacy while using the phone my intention was to switch only the speakers on the headphones, but still using the internal microphone of the Shift. That would require some small modifications to the jack-port.
I didn't get it exactly how many motherboards are there inside the Shift? Are there in 3 pcs, i.e. Vista mb, Winmo mb and phone mb, is that right?
Hi Axel,
The Shift has 2 motherboards - Mobile and Windows Vista. But both are connected where the 2 boards get into contact with each other through connectors on each side. There are no cables/wires involved but just direct connectors between the 2 motherboards where they come into contact with each other.
Apparently most of the connections take place inside the printed circuit boards so you cant tell which connection goes where. But of interest is that both the mic and the audio jack are all connected to the phone motherboard yet they dont work in the mobile side. So either these have been physically disconnected within the circuit board or it could be a software issue. Remember how we could not use GPS or phone functions until the great rom breakthrough by the likes of Thaihugo and Cmonex....? I still believe that the issue of wired mic not being active is a software issue.
But the SD Card is a different story as this is attached to the Vista motherboard. It is very likely that there is no physical connection between the Sd card and the mobile motherboard. Well I might be entirely wrong here as come to think of it there is a solution about accessing SD card from the windows side but Vista has to be on...... Will look for that thread and read some more and see how the connection is established.
By the way I did home-made switch for the dead shift's motherboard. The Shift was able to power up and boot but it appears that the Lcd cable is dead (or perhaps the lcd screen itself is dead but most likely the problem is with the cable). I was able to connect the Shift to the Tv through a Vga cable. But I could not do much with it as the Vista software appears to be corrupt. Further the HDD connection cable too is not in very good shape. I hope to get the Hdd cable to be able to do more tests on this Shift using the Tv as the external monitor.
This other Shift will be the official guinea pig and I am willing to make various tests with it as soon as I get a working Hdd cable and re-install windows. However there is a big limitation to this too because apparently the windows mobile side does not show in the external monitor. In other words even if you switch to the mobile side using the Shift button the external screen does not change and is only active for Vista......
But I can tell the snapvue side is active as I was able to call the sim card number inside the Shift I was using for tests.... My intention is simply to use this Shift with my Tv for internet connection and as a basic pc in the living room. I confirmed that the internet connection to the Vista side is active even without having any access to the windows mobile screen. I made these tests with the Hdd cable from my good Shift for a few minutes and thus did not make extensive tests.
So guys I will get back to you with more tests once I get a working Hdd cable which I may have to import from China (parts4repair.com). I might then end up with 1 Shift and half a Shift......

After playing with my other Shift as described above I believe your problem is not the motherboard since the power light is coming on and the fan is coming on when you power your device. So chances are that your Lcd screen is not getting any signal from your Shift. Yours could be a simple problem with a disconnected Lcd flex cable or problems with the lcd screen or damaged lcd flex cable. Easiest test for you is to get Vga cable and test your Shift using an external computer monitor or tv that supports Vga in cable..... Hope this helps.
Thanks PlayStation, great post, thank you for your endeavour!!! Looking forward for further details.

i9500 Freezes unexpectedly when it is a little bit hot

Hello guys I really need your help. As you can see in video which you can reach with the link given, my i9500 freezes when it is a little bit hot. It happened when I flash a rom and I couldn't get rid of that. I don't think that it is about firmware because I fully installed the stock rom but it didn't work. It happens in every condition. I don't know what to do. What is the reason of it? What should I do?
Please help with every ideas you have.
Link : https://youtu.be/5MowcMJDCuI
It might be a hardware problem.
is there any way to solve it?
Certainly. But this implies that you take the phone appart. You do need some technical know-how.
So in your opinion which part of motherboard causes this? There is no talented techical persons here nearby, maybe I will try to swap crashed parts of it.
There aren't too many parts in the phone. The main parts are the mother board, USB data/charge port, speaker, camera, headphone jack.

Changing parts is also tricky. If you're not careful you might have a whole different problem than overheating issues.

Phone charger probably burned my S5 overnight

Hello everyone,
I have a problem with my Samsung Galaxy S5 and I was hoping to find some help here.
When I got up this morning I unplugged my S5 from its charger. However, it was turned off which is usually not the case as I usually don't turn it off. After trying to switch it on for several times and failing with it, I asked Google for help.
What I found after some research was a hint that it might be a problem with either the battery, the charging cable or the mainboard that has been damaged/burned.
Long story short, after some testing (tried a new battery and charging cable) and going to two different repair shops, it turned out it probably is the mainboard. (I'm writing 'probably' because I don't trust those shops 100%. I left my phone at the second shop for about 2.5 hours though, for error diagnostics).
Nevertheless, what I want your help with are these three questions:
1. If there really is a problem with the mainboard, how can I find it all by myself? Is there a way to tell it apart? And is there a way of telling which (more or less) exact part/entity of the mainboard has been damaged?
2. Let's say the mainboard is damaged. Is it possible to fix it? And by fixing I don't mean to just replace the mainboard, but really fixing it. (Ofc I know it might depend on the part that has been damaged, this is why I asked Question #1).
3. Assuming there is no (feasible) way to repair that mainboard. How can I possibly save the data stored on the internal memory? Is there any Software available that can still read the storage? Or do I have to physically move the memory chip to a functioning mainboard, e.g. by soldering?
Any help is appreciated. Thank you in advance!

My personal opinion would be that one or both of the following may have happened.
1) Bad Charger - Chargers can go bad without any warning that resulted in your battery going dead.
2) Bad Battery - Also can just go bad suddenly or over time.
The motherboard of your device has a type of regulator that will only allow a certain amount of voltage/amperage to pass on to the battery. It's extremely rare for a proper charger to kill a motherboard (unless jumper cables were involved LOL!).
Your best bet is to replace both the battery and the charger but, this is only a suggestion/recommendation.
I wish you the best of luck!

Thank you very much. Unfortunately using a new battery and a new charger didn't solve the problem. And my charger is still in use for my backup phone, which is a Samsung Galaxy S2, and it's still working fine.
So it appears it really narrows down to some physical damage on the board.
After some more reading I found out that professional data recovery uses eMMC adapters for their SD card slot, as eMMC is downwards compatible to MMC. Unfortunately those adapters come at a cost of 85-230$, which of course is still cheaper than paying for professional data recovery, yet too expensive for having no actual clue how it even works. I still didn't figure out what the data will look like once I get access to the memory chip. Will I have to use an android emulator to get to the data? Will I have to use some special recovery tool to read the memory? Or is the eMMC already formatted in such a way that Windows can easily read it?
Anyway, what I'll try now is the cheapest method that came to my mind: mounting the eMMC on some sort of USB stick, that I found on aliexpress for 5$+shipping (it's called "USB3.0 eMMC 153 169 U disk PCB NS1081 main controller without flash memory for recycle emmc emcp chips").
I hope this will suffice to read the memory, somehow.
Any comments on this?

Unfortunately Motherboards can go bad suddenly too but, there's a few options.
Option 1) You can try buying a USB JIG from eBay for $3-5, it's a tool designed to force your device into download mode. It isn't guaranteed to work but if it does you can flash the firmware. If it doesn't then you only lose $5.
Option 2) You can see if there's a friendly and helpful individual at an official service center for your device for a JTAG service. Though it isn't guaranteed to work but, some may do it for nothing while others can charge up to $50 +/-. The fees are all individually determined by them. Some have the JTAG service there while others require it to be shipped to another shop to repair them and then ship it back to you.
Option 3) You can always purchase another compatible motherboard and put the new one in your device. This is an option you can do yourself if you're careful.
These options/suggestions are the best that I can think of at this time and I hope one of those will work out for you.
Good Luck!
