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?

Before anyone jumps on me, I've been going through the Wiki and forums extensively, and found just one similar problem. Which wasn't solved...
My HTC TyTN/Hermes 200 won't boot up anymore. It is totally dead. I even can't get it into bootloader mode. Screen stays blank and the LED is off.
Put the (3 months old) battery in another Hermes to test it, and it's at 100% charge.
My Hermes shows a steady red LED when it's plugged into power without the battery in, and no LED at all when the battery is installed. The red LED turns off when the battery is installed while there's power going into the unit.
I've left the battery out for at least an hour, plugged it back in, same results. Like the other guy I tried the "pull power, pull battery, plug in power, plug in battery, reset" trick http://forum.xda-developers.com/show...6469&p=1077622 - to no avail.
Does anyone have any last resort ideas on how to get it to at least come back up to a boot loader screen ?
check the battery contact points on the phone. the hermes shows a red led when its plugged in but without a battery
... have you ever dismantled your hermes? your screen ribbon cable may have dead tracks or not be connected properly
just a test on the opposite side of the battery connectors with battery removed press firmly without putting pressure on the LCD, this worked for me when i had a white screen on power up.
if this fixes the problem you may need to actually dismantle the back and put some flame retardant electrical tape on the back over the existing tape to add an extra layer of pressure and retension

Yes, I have cleaned the contact too, nothing. And the battery is OK for sure, my colleague's TyTN runs on it without any problem.

In fact I have, I have totally dismantled and reassembled my TyTN yesterday afternoon, nothing.
the only other problem may be that when being dismantled you may have damaged some sensitive components, Electro Static Discharge will fry sensitive CMOS components, they do not like it at all, whenever dismantling you should wear an earth strap, any time i dismantled mine it was on a workbench with a static mat and i was earthed through the mat.
but this is one possibility, the only other idea is to swap main board and displays with another that works, finding someone willing to allow you to do this with a working hemes is the tough part.
thats as much all i can think of for now
R.I.P. my trustful Hermes 200
Thanks all for your assistance. I have come to the conclusion that my sweetheart is no longer among us. May she rest in peace.
I have obtained a (2d hand) replacement yesterday. May this one last longer.
I'll keep the old TyTN for replacement parts.
Oh well...
hi! i have a dopod 838 pro. and it suddenly cant turn on. i was just texting then it went buggy (hanging up) then i did a soft reset then all of a sudden it didnt turn on. i was charging it at that time.
the phone never got wet, was never dropped. i installed the official wm 6.1 rom and it had been running for more than two weeks so i dont think the problem was the ROM. battery is good since i still get two days of battery.
i have tried hard resets, used the usb connector to power the phone up. havent tried another battery though. is there any way i can diagnose the problem before spending for diagnostics in the shop?
this was an observation: when i remove the battery and connect it to the charger, LED is red then it disappears when i replace the battery. no amber going. how do i test if the problem is in the battery? battery connector? power? or (please i pray not) the motherboard itself?
a little help please! more power to this forum. thanks!
gab
Would suspect the battery... Red LED WOULDN'T turn on if this was a hardware problem, broken battery connectors and such. However, if you install the battery when the red LED is visible (connected to charger without battery) & it doesn't turn amber (charging) then I'd suspect the battery has died.
Take in to a shop and ask to try a battery, easier if you know someone with the same phone.
Cheers...
i have it sent to the authorized htc center here in our area. the technician tried using another battery but still it didnt work. my phone will be left at the shop for about 4 to 5 days for diagnostics. the technician said that theres a possibility that this may be a motherboad problem like the board short circuited.
but how come? how can this happen?
can anyon confirm that this is a motherboard problem? awh! cant wait for the result of the diagnostics.
thanks!
Hi, I've unfortunately broken my hd's lcd.
I've replaced it at home, but after I turn on the device, it vibrates one time, then I hear the htc opening sound, but there is no image or light.
So I guess the device itself is functional, but there is a problem with the lcd.
Somebody told me, that if I put on it a new stock rom it would fix the problem.
But when I connect the hd with an usb cable to my computer, nothing happens, there is no connection estabilished, the computer doesn't see the hd.
When I plug the device to charge, it charges.
So how can I replace the rom on my hd? :S
I've also tried to update the device from an sd card, I've formatted an 8gb sd card under win7,put on it an official rom, with the device turned off pressed the vol down button+the power button,then release the power button,the the vol down button,then press the power button.
But it's the sam: vibrateing when turning on,then after 30secs the htc sound,but no update..
Have you taken your HD apart again and checked the physical connection of the ribbon connectors for the LCD and Digitizer? They have to be pushed all the way into the socket and the sockets must be locked in a couple of different methods depending on the connection type. If they aren't in properly, you would probably experience the problem you've described.
Before trying to explore software issues, make 100% sure that you don't have a hardware issue.
I had the sync connection issues, then I found this thread. http://forum.xda-developers.com/showthread.php?t=524619 I followed the instructions and was able to get connected again. It's worth a try.
if you change the lcd and don't get any image on the device
I would think
the lcd you got is dead
or the image display port of your motherboard is dead

I also have the same no image issue. I have also tried a second LCD with no luck. Once I was able to connect to the phone again, I flashed the stock rom from HTC, still no LCD. Tried leaving the battery out overnight, still nothing. I have been able to get the phone display to work by putting the phone body minus battery by an exterior window for about 1/2 hour, its cold in my neck of the woods. Pop the battery back in and I have a screen again, for about 5 minutes... One time I was able to get the phone to stay on for over an hour by doing the above steps and then right after putting battery back in cool phone, I immediately synced up with my PC and it stayed alive.. I don't know what the deal is.
Update for those who care. I have been playing with the cold phone/battery and have found out the following:
Cold battery/warm phone = no LCD
cold phone/warm battery = no LCD
cold phone/cold battery = working LCD every time.
I have also been able to use the phone, after both batt. and phone are cold, for as long as I want as long as it stays active and does not go to sleep. The phone will not come back on if I let the screen turn off by itself or if I push the power button to turn it off unless I cool it off again. I plan to call HTC in the morning to see about a repair, but have had fun playing with this weird situation.
So,I've opened up my HD and found out, that the data cable that is connected to the volume button has been detached from it.
Is it possible to solder it back without changing the piece?
My hd is still in the srvice shop for a price offer, but after I will get it back, I will try your cold lcd/battery thing.
Will it work with the fridge too? Because it's getting warm up here
So,if I undertand you correctly: after the lcd and the battery is cold, the lcd works, and if you connect it with the pc, it's stays alive until you put the screen to sleep,than it's dead again?

The cold trick has worked every time for me. I only hooked it up and had it on while connected to the pc once, but I think it should work again.
On another note, I heard back from the repair center and they wanted to replace the LCD (for $300) and I then explained to them that the LCD was not the problem and then was informed if it was indeed the mainboard that needed replacement then it would cost even more... I tried to plead with them that it is a common problem with HD's and even though the warranty is void I think they should cover it, didn't work.. It's times like these that I curse my curiosity and ability to repair my own things.

As far as the fridge goes, it should work just don't leave it in too long.. if it gets too cold then you might get condensation when it heats back up.
Forgot to add that I got my HD back from HTC yesterday. Got excited thinking they went ahead and fixed it for me!! But no... It worked just fine for about 5 hours after I unboxed and put my battery back in. Was turning on and off like normal, then after bout 5 hours it was back to the usual working phone with no LCD. I did notice that the screen was pulsing, for lack of a better term, it would dim then come back up to full brightness, then dim and repeat. There has got to be a way to fix this! (other than the mainboard replacement)
I bought an hd2 that would not power on from somebody on ebay. I have some experience with small electronics and phones so I thought I would give it a shot. The phone also came with a set of beats tour headphones and a power mat which I can use with my working phone (or more to the point my wife will steal) so I don't feel like I got ripped off.
Anyway, this phone is completely dead. The person that sold it to me said it was running an Android ROM and then was just dead one day. I was really hoping that he just let it power down all the way and it wouldn't charge because I had read that hd2s will not charge when powered down if they have magldr installed. He didn't sound too savvy about phones.
There is nothing going on at all. No LED when plugged in. The battery doesn't get warm. Nothing happens when I press buttons and it doesn't mount or anything when I connect it to a computer. The water indicator is solid white.
I have tried a different battery which I charged with an external charger and different chargers etc. It feels a little like the usb connector could be loose. I can understand how that might prevent it from charging but it should still work with a charged battery right? Same with the battery connectors. I know the pins can have issues but it should still power on when plugged in right?
Could something be loose inside? I am thinking about pulling it apart and trying some surgery.
Does anyone have any ideas? Any help would be greatly appreciated. It is a beautiful phone in perfect condition so I would really like to use it.
is it a tmous? (red end green send keys) and if so, does it ask for qualcomm drivers and then say drivers not found when you usb it to the pc?
Sounds like you may have as hard bricked HD2(I am betting you have a TMOUS HD2). If it is hard bricked it can only be revived with JTAG. If it turns out to be hard bricked PM me and I can point you to someone that JTAGS HD2's all the time and for a very low price.
Now if none of the battery pins are not bent and you do have a charged battery. I would sugest you try pressing the power button several times rapidly. I have to do it with my HD2, the power button on the HD2's are none to start giving users problems. Also make sure to hold down the volume down button while you try to power it on to see if it boots into the bootloader. If you can not get it to do either of these then as I said before you are probably hard bricked.
Thanks for the info and quick replies. Yes, it is a tmobile hd2. I guess I should have mentioned that.
I get nothing when I plug it in to a computer. It doesn't try to load drivers or anything. I tried two different computers. I also tried the rapid fire on the power on button but I didn't get anything.
I will PM you about getting it jtag unlocked. It is such a cool looking paper weight.
hmm i wouldnt be so quick, , since it doent respond to usb, it could be actually broken, not just radio bricked, and jtag may not fix it. If you are already fairly happy with the other items in the purchase, it might be better to simply sell teh phone as unknown condition - parts, recoup a few $$ and buy a cheap working one. JTAG will cost you, not a lot, but enough to make it worth considering other options.
my sense of adventure will not allow me to give up too easily but I am leaning that way. If I could get $50 for it, I could buy one in working condition and I would still be coming out ahead (I paid $130 but my wife would smack me if I tried to send back her new headphones). The only thing that gives me pause is that it is in such awesome physical condition.
I have the pry tool and other stuff I need to pull it apart so I may just see if a cable is loose. I mean, if it were a big computer, I would be checking all the power connections especially since the guy said it just died. That said, I realize that he may have fried the board somehow. I haven't tried the powermat but I am wondering if it is screwed up. I also wonder about the loose usb jack. He may have tried to jam a different kind of adapter into it.
I just tried another power cable and there connector is definitely loose. Maybe this guy dropped it even though he specifically said he didn't.
Oh just thought I would add. The Micro USB port is sodered directly to the mainboard of the HD2. So unless you are very familiar with sodering I do not suggest you try to replace or repair the Micro USB port. It would be simpler to just replace the mainboard, that would solve the USB port problem and the possum le bricked problem all in one. But that might be more money then you want to invest in the device. So as Sam said, don't count out selling it for parts like the screen and digitizer and such.
Ok thanks for the info! I definitively do not have the soldering ability to work on mobile phones. I don't want to mess it up to the point that nobody will even buy it for parts. I could see trying to sell it with solder on the screen or something. I also wonder if it would make a difference because it doesn't even work with a charged battery. I am thinking that the main board is toast but I might open it to see.
I think I saw a mainboard for $50. I think it would be cheaper and less risky to just buy one in working condition.
nah i got the same bricked eu hd2 phone but what do you think? Service recognize the magdrl and android os?
i'm disassembling my HD2 after it dropped in water ...
the screen were working properly but while i', trying to disassemble the digitizer with some parts the screen became black
what can i do ?
thanks in advanced .
Yes it will boot normally with those parts as I do that to test all HD2s prior to final build up.
Issue I see is button board cable looks to be cut. I use a spare button board cable to power phone on as when laid out like that the original one obviously will not reach socket on mainboard & a spare button board plugged in mainboard is easiest route for this kind of testing ...

thank you for replying ...
actually I'm using an external wire to power on the device because my button board cable is corrupted ...
do you have any idea about repairing the black screen while booting ?
i can't buy any part for my device ... i'm in the besieged "HOMS" in Syria
Might be best let it dry out further before adding power as normally leave handsets for about 4 days to be safe ...
What signs of life are you getting when powering on with your wire ?
If on WM OS you could use MyMobiler to try & get screen image to PC as would give idea on actual possible issues. could be ribbon or connector or worse.
Not a good time or location for a wet handset :-S good luck ...
