Hello, the other day my phone broke and it wouldn't turn on, I knew it wasn't the screen it just simply wouldn't turn on. So I got my uncles phone and swapped the circuit boards. And this one would turn on. Would it be possible to back up that circuit board to Samsung kies then load it to this note 3 I have now?
How was the phone broken if swapping the circuit board to another phone made it work again, I would of thought that usually any problems causing a phone not to boot would be on the main circuit board?

Hello,
I've been flashing my Blackstone since I bought it a year ago, used many different ROMs, TASK 29, latest ROM I used was MaryOne - Build 23568 - WWE [300410]. There were some minor problems but otherwise it was working good till today.
In the morning, phone was connected to USB for activesync and suddenly died, it doesn't want to turn on, not even a diode turns on when I plug in the usb cable to show that it is charging, anybody could give some help? It is in warranty but I'm not sure, what they will say if they'll get in and see cookend rom in it any solution how to avoid it?
Same problem here. Has been flashing Energy ROM for the last couple of weeks but I dont think it is a software issue.
Prior to the present state of totally dead (ie. no LED light when charger is connected, cannot power on, pressing ON switch will not power/turn on phone neither can I hard reset), the phone behaved strangely by resetting itself during video play and phone switched off by itself.
I suspect it a hardware issue. If so, which parts and where can I purchase it without going thro HTC authorised dealer to pay a ransom! Or its time to dump the phone and upgrade? - HELP!, any suggestion?
I have no idea what you could do, but if you decide to
upgrade, please contact me. I would buy the broken phone
because I need a tiny metal part from it, as you can read in my other thread.

I had the same problem a couple of weeks ago.
I sent the phone to htc and they changed the motherboard. This took alltogether about 4 weeks.
bgumble,
Thanks for your input. I could only find motherboard flex cable online : http://www.globaldirectparts.com//ProductDetails.asp?ProductCode=HTC730080&Click=1710
Maybe you can tell if the motherboard also house the flash ROM? If that is the case I guess the motherboard is only available via HTC service centre! or purchase a faulty unit from ebay with a working motherboard.
Yes the motherboard houses the rom.
the only other major pcb (print circuit board) is the top flex pcb which AFAIK doesn't house any of the flash storage or any other major chips.
if you want to DIY repair, you can use the service manual and I have some tips/advice in the bottom link in my sig, even tho its to change the screen, you can omit a few steps and use it to change the mobo if you're confident doing such a repair.
IIRC: mobo houses the cpu, ram, flash, various transistors and i/o rails, the usb socket, radio nand, coax rails. it also is connected to the wifi/gps/bt/sd/sim pcb, but they are seperatable.
Thank you for you info, qwertylesh.
Having replaced the LCD for TYTN II and checked the service manual and video to dis-assemble HD I think I can manage. But the only problem is getting the spare part, motherboard!. I am hoping to bid for a faulty HD but with a working motherboard on ebay.
I tried placing my dead HD, well wrapped in plastic bag, in the freezer for 2 hrs and then out in room temperature for an hour. Replaced battery but same results - will not power on.
With the charger plugged in, there is no LED lights but testing the terminals which comes into contact with the battery terminals there is voltage (4.19v), meaning - it is charging the battery but the motherboard fails to bootup!
Would it be possible to fix the motherboard? - a long shot!!!!
depends on what is exactly causing it to not boot up I think.
weather its a problem with the flex PCB or the ribbon + power button PCB at the top of your mobile or weather it is actually the motherboard at the bottom.
My HD was dead during upgrade
My Phone was dead during upgrade can anybody help me?
I found a way to repair using JTAG method but unfortunately i stuck up unavailability of JTAG pin outs.
Touch HD Mainboard
I too am in need of a new main board. I packed up my touch HD and transported it in it's original box 150 miles couple of week before I powered it up again and the phone starts, responds to volume up/down and connects via active sync. Basically it all works apart from the screen, no back light and can't see anything on the screen. The phone will charged the battery but there's no light on the power button. I've opened the phone up and disconnected the flex PCB and the connection between the main board and the screen but still have the fault.
Has anyone managed to get hold of one?
Hi guys
been a while since i got around to xda, knew i ll back sooner or later so here i am
bought a S4 mini dual sim GT19192 two months ago, great phone but since two days there's a crazy issue am facing
When i turn the phone off
As soon as it goes off starts vibrating with a second or two gap (feel like somehow its not totally off) and keeps doing so until battery is taken out, if i wanna turn it back on and put in the battery it starts the vibrating drama again, simply cant get it to stop vibrating/ cant turn it back on, the ONLY way to turn it back on is connect to laptop or charging unit via usb cable (the battery icon comes up, vibration stops, and can be turned on)
i did some research where this happened to a S3 phone, in most cases it was the power broken or stuck out of its place on the inside, so i opened up the back, took off the side that contains volume buttons power button, put the battery against the pins and bam same problem
this means each time i turn it off i need to connect to laptop or charging unit to turn it back on
can anyone please help?
just in case this set is in brand new condition never opened (till i did) and not rooted, hard reset dint help either
am really
anyone?
very disappointed to see no responses
I think it is a faulty battery problem.check your battery in another phone.

Update 1
I've discovered that if I plug in the phone, I am shown a gray battery with a progress wheel. In the past, the phone has gone less and less far into the boot process before shutting down. Thinking about it again, perhaps it's a power issue. I've ordered a new battery and usb board on Amazon, total 15 USD. I've already disassembled the phone and I'm waiting for it to arrive. FWIW I do see some physical damage to the inside "tongue" insomuch as two of the pins are just floating with no plastic. That is to say the plastic is broken off and missing.
Original Issue
Hello everyone:
I bought a Samsung Galaxy S4 (AT&T Branded) SGH-I337. I thought it was working. When I insert the battery, it boots up about 1/10th of time, but only about halfway. Occasionally it does the same thing when inserting a USB cable (I don't recall if it was to a PC or a power supply). If I can get it to boot, I CAN get into recovery or download, but it shuts off the same way. Someone took a look at it from a repair shop and said it may be a software issue.
I have tried disassembling the phone and using canned air on the power key, though it didn't seem to be the issue in the first place.
I saw a video from thailand on youtube where a person put in a microsd card, connected a power supply to the battery terminals on the phone, then connected a usb cable. The phone booted. I think the idea was that the original firmware would now have to be installed. Any idea what this is or how to do it?
Thanks for any help!
*** Sorry missed your update!!!***
Would you have another battery to try 1st before dismantling it? They are very cheap to buy
No, but I bought a battery and usb board for a total of $15, so if either works great. Does the battery cause this issue at times?
Just replaced the usb board and battery. Still only boots to a point. No idea what to try next. Any input appreciated.
I had the same issue with my previous Samsung Galaxy Express, it turns out that this issue was caused by the power button being worn out and stuck as if it was pressed down. If you look on YouTube you can find some temporary fixes to allow you fully boot your phone. Although ultimately if this is the issue then you will have to get the power button replaced.
My perfectly working Galaxy S5 was put for charging at night and the phone wouldn't turn on in the morning. I tried restarting it and at times the "Samsung Galaxy S5 - powered by Android" flashes for a second or so and then the phone dies again.
I tried rebooting it, unplugged/replugged the battery, removed SIM and SD Card and tried to start the phone but nothing happens. On charging the phone, the screen does come up to show that the phone is being charged and as of now it is 100% but still won't power up.
I must add that the phone has had its share of falls during the 2 year usage and there is a small discoloration / crack like effect on the top left hand corner of the screen which however cannot be felt by hand by rolling my finger on the screen.
Samsung guys claim it a screen problem that needs to be replaced however an independent repairer is confident that screen is OK and it has something to do with some other hardware of the phone. He even removed the battery and connected a multi meter to the point on the phone which connects to the battery, tried starting the phone and the meter would show some current getting drawn and then come back to zero. He claims phone is not able to draw current from the battery.
Any clues what could be the problem and how to rectify it. I have loads of data I don't want to lose on the phone.

Can you boot into recovery? Have you tried flashing a new firmware on the phone?

Phone isn't responding at all. No matter what I do, at the most the Samsung screen flashes for like 30 seconds and then the phone dies again.
On connecting with a computer the computer begins to recognise the phone and starts installing drivers for the same however it never completes the job.
So not sure how to flash a new firmware if the phone isn't responding at all.
Bumping the thread.
Another reason for this behavior is that the battery has no charge. Battery can be damage and no have charge at all
I would in this order
do you have another S5 available?
exchange batteries and see behavior
do not have another S5 available?
try to charge with a universal wall charger.
or it seems you have a tester. Make sure your battery have charge
Checked battery too but that doesn't seem to have a problem. Tried with other batteries also.
A local repair shop told me there's a problem with the boot IC.
My follow up question is can I replace the mother board with another Galaxy S5 motherboard? Are all the motherboards of Galaxy S5 compatible with each other?
I'd be careful when changing the motherboard. You *DO* need to find a compatible board...In other words which ever variant you have should be the variant you look for to source the donor board.
Also, you say you have data you want to recover? Swapping out the motherboard will remove every possibility of recovering that data; as all the flash storage is contained on the motherboard.

How to locate a compatible motherboard? In other words how does one identify the variant of the phone?

All the information you need is on the sticker underneath the battery.

Interesting piece of information.
I took the phone out almost after 8-9 months today. Tried to power it on by pressing the ON/OFF button and the phone came back to life without a glitch. There was almost 52% charge, date and time were spot on. I couldn't recall the pattern, as a result I couldn't unlock the phone.
I decided to wait for a while for my partner to come back and put in the correct pattern password and left the phone unattended for a while. In between I kept checking and the phone remained ON all the time.
Unfortunately, I decided to charge the phone while my partner returned. After half an hour or so I pulled out the charging cable and checked the phone for 1 last time. Phone was still ON. I left it untouched for a few more minutes.
As soon as my partner came back I told her about the phone coming back to life. She pressed the ON/OFF button to bring up the screen and key in the pattern but the screen just didn't come up. I have tried number of times since then but nothing.
Phone is dead again atleast as of now. Thinking of keeping it back for few more months and will try again.
In the meantime any sort of help will be highly appreciated.
Please note more than the phone I am keen on the data inside it. Need to recover it.
Hello XDA Members !
I own a Galaxy S8 G950F model and I bought it with SIM Card Reader known to malfunction...the issue is that I odered a new SIM READER and I failed replacing it. What I mean by failing is that I haven't managed to remove it from the motherboard, even after I heated up that zone at 200 degrees Celsius. After I realised I need to contact special repair services I reassembled the phone and the volume up button was stuck as it was pressed but it was some motherboard issue, not the button itself. So I dissasembled the phone 3 or 4 times and I still couldn't fix the issue, few minutes after that phone went dead and came up to Samsung logo after 5-6 tries of reflowing the hole motherboard then went dead and stayed dead...
Now I know the motherboard might be dead but fun fact is that if I connect the phone to my laptop via USB, if I keep Power Button pressed phone connects to PC as "Exynos 8895" but no drivers can be installed and phone storage is not showing up...also I want to mention screen has no input and no LED is turning on when charging or connecting to PC....
Not so worring about the phone, any ideeas are welcomed, I own a P30 Pro now and a motherboard for S8 in my country is around 80-100 bucks but it makes me put some questions and maybe I'll find a workaround...
Any ideeas?
