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?
replaced my lg g2 screen again for the third time and have done over a thousand phone repairs with no issues like this phone will not accept power turn on or vibrate battery was disconnected before anything was done worked perfect before except bad lcd i have no idea or what board to replace im thinking possible the battery somehow shorted,but then it should still get usb power? or the board where power button charge port and everything else connects?
Hello my daughter do have this mobile phone. She came with it to me and display was filled with random color stripes over whole display ( verticall ). I have tried to restart phone but it wont turn on no single mark of life ( no charging marks of charging not even single vibrate if i try to turn it on ). I have tried to do restart or go to the download mode but nothing has work. She told me that she has dropped her phone but only thing that was broken was cover glass and not single scratch on display etc. Any ideas what can be broken? Could some cable got disconnected by dropping it?
I think that the LCD has a mechanical damage. I saw a phone once. The display glass was fine but not the lcd. It had wierd random color lines.
In that case replacing the LCD display was the solution.
You should try to charge the battery. Maybe it is empty but you can't see the charging?
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?
Hey.
I've tried to fix my phone screen's digitizer (first idea was to unplug the screen and plug it back in, which kinda worked). The phone worked fine while disassembled and I did a stupid thing - I turned it off by disconnecting the battery, as the power button was not working while disassembled. After I put it back together it did not turn on anymore (disassembling it again does not help). The notification LED is flashing while I'm holding the power button, it also starts flashing when I plug in the charger.
What could be the issue here?
EDIT: I figured out the issue - I broke off a tiny component on the motherboard while putting it back together. Took me a while.
How is the phone now? Did you replace the motherboard or lcd display? Did you repaired? Is the phone fixed?
