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...
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?
My HD2 doesn't turn on, doesn't go into boot loader, and cant soft reset. Can I officially say i bricked my HD2? And i cant even get it replaced because the camera is somehow cracked, and that supposedly "voids" the warranty.
And Im quite sure you need a JTAG to fix it, correct?
if it was a 51 radio brick, then yea, JTAG is it.
actually, it wasnt a 51. radio brick. I installed the Eugenia Rom through CustomUU while my phone was connected, it installed fine, and then it wouldn't turn on?
wont turn on at all? nothing? black screen? no charge light?
check the battery pins.
Nope, nothing at all. And by checking the battery pins, what should i be looking at?
just to see theyre all in a nice neat line, two one two, none bent up/down. it happens a lot.
other than a 51 radio (or 2.04.50 and 2.05.50 radios), battery pins or a discharged battery are the only reason i can think that would cause complete dead phone.
hm, I think I'm on to something here. When i plug my phone into my computer, it installs a driver. I forgot what its called, but that's all it installs. I cant access the phones files, but i thought i would let you know, maybe it could help me in the long run.
qualcomm? yea, the radio bricks show up as a qualcomm device.
try leaving the battery out for a while, (half hour) then plug in usb (wall charger, not pc) and then put the battery back in. this will stop the phone trying to run on like it normally does when you apply power when the battery is in (thus draining even the dregs of power, possibly affecting the charge circuits ability to start charging, , not very common, but not unheard of either), and with a bit of luck the charge light will appear and all will be well.
gotta go, 3am
good luck.
Thank you so much man,I'll try... ill get back to you about it tomorrow.
Erggg, nope, it didnt work =( Thanks for your time, and thank you for trying to help.
how old is it?
is it warm on the back bottom part of the phone?
Put it in the fridge for 15mins, then try to boot up.
Also see if you can try and put your battery in some one elses HD2 or charge your battery in their phone.
Its pretty hard to kill your HD2.
(i just dropped my HD2 in for a service/repair as my motherboard/cpu was overheating.- had to flash stock rom and spl back though)
I got it two weeks ago Its not warm, but ill try it in the fridge...... and I just did that a couple hours ago, we switched battery's and still no luck.
Refrigerator did not work either =/
can u do a hard reset with the volume up buttons and the power key? reformating the device to default?
Pull out ur battery, press and hold the soft reset button, hile holding down the soft reste button place ur battery back in. While still holding down the soft reset button pres and hold the volume down + the on/off swith and see if it will boot. U might need a friend to help u with holding down al the buttons. It worked for me...
Read ALL the earlier replies. Mine seems "cracked": battery won't charge in phone, via USB cables (2 cables, 2 batteries - one new & fully charged, two USB power souurces, including a car's 12v DC source).
Did all the above hard & soft resets, etc. Nothing works. Phoned HTC AUSTRALIA - MUST send it hundreds of miles (or kms) away to the original Telstra dealer, since HTC does not allow any other type of warranty claim in Australia.
On the phone's pins that contact the battery - they are flexible: up, down, in & out. Being "in-line" does not mean they work.
Not sure why the hardware crashed. Have not upgrade ROM or Android. Won't recharge the battery in-phone with SIM, micro-SD in nor out of the phone.
Wanting for a separate external battery charger (only a few $$) from eBay. Might take the phone to a dealer, and see if they can get it to recharge the battery via the USB cable.

Since yesterday my SGS is having a very strange issue: It seems that the power button is stuck on pressed state. When the phone was on I had the power menu appear and the phone shut down. Then it started again, only to turn off shortly after the second screen during boot, then looping in that state.
When I remove battery and put it back it automatically starts and then bootloops.
I can't get into recovery as it turns off before recovery can start. I can get into download mode but only for 3-4 seconds till the phone turns off again.
I removed the backplate and can't see any visible damage to the power button. Between the power buttons pins on the board there's a voltage of 7mv with battery removed, in case that means something to anyone.
So 2 questions arise:
- Any ideas on how to fix this? (apart from ripping of the power button which I'm not even sure would help)
- Any ideas how to get into a mode where I can backup my data or at least flash a stock rom? (Currently on CM9 with devil kernel and the devil logo shows for a second in the bootloop, not sure how the techs would like that if I was to sent it in for repair)

Has there been any water damage to the phone/button? Sometimes this can cause the button to short. Or it might just be stuck, does the button physically click in as normal?
It could also be worse and have an actual hardware issue with the motherboard/power button interface
there hasn't been any water damage. actually, it's been used in the rain but that shouldn't really hurt a phone... just in case i let it try for quite a while but the problem didn't go away.
the button clicks as it used to do, no sound of water or damage there.
problem hardly could have been worse as the phone is completly unusable in this state as i can't even turn it on.
Hi,
A friend has just handed me an abandoned SGS with precisely the same problem.
The power button itself feels fine, ie it doesn't feel stuck, and you can feel it clicking as normal. I too removed the backplate and can't see any visible damage to the power button.
I note however that the water damage indicator 'sticker' mentioned here: "samsunggalaxysforums.com/showthread.php/4674-Galaxy-S-I9000-Service-Manual-How-To-disassemble-your-Galaxy-S"
is completely white, indicating possible water damage at some point.
Any ideas for a fix, or do you think it would be economical to seek a fix from a hardware repairer?
I can replicate the problem as described by XlAfbk above, by simply holding down the power button on my working i9000.
i did sent to phone to the only service location samsung lists for germany. they claimed it was water damage and refused to repair under warranty. repair would have cost ~280 euro.
i'm waiting for the unrepaired device now and will try to fix it myself, in the meantime i got a gnexus
Ok thanks. Please keep me posted if you do find a way to repair it yourself.
Until then, I guess mine's spare parts!
no more warranty for you? if you're in germany PM me for a repair shop.
ebay has power button replacements for ~4€ that you could try soldering on, replacing the original one, if that's what's broken for you. I checked mine with a multimeter and as there's still resistance it's not the power button for me.
uhm, I actually did fix it... while it's not completly back to normal i can at least turn on and off the phone, just turning display on and off with power button still doesn't work
some dust had gathered on the board, apparently shorting a circuit. just grab a brush and some canned air and clean the board.
i cleaned the main board at the very top and the bottom one near the middle (PM me for a photo of the location)
Nice that it almost works now. Just thinking what an asshole Sammy is, they want more money for a maybe ~20€ repair than the device costs bought new.
the repair wouldn't have been 20€, they'd have replaced the whole mainboard for me, not just the power button. I have no idea whether just replacing the power button would help, just brought that up as that's the one item that could possibly be it and you can get for cheap.
my power button got worse again since my previous post btw. so something else must be wrong as well.
After my phone was on a rainy trip, I am suffering from the same issues as well. I checked the resistance of the power-switch, and the open-circuit resistance measured to 30 Ohms, while the closed resistance measured to 0. Of course, the open-circuit resistance will not measure the switch isolated, but still, I'd expect something in the range of at least some Kilos. Hopefully, the switch will function normally in some time (if the switch is the only problem).
if it doesn't fix itself remove the mainboard from the housing, check it using a strong magnifying glass for any traces of water (tiny white residue spots) and carefully clean them using with a small brush (and nothing but that!).
of course doing that will void all warranty!
I completely disassembled it in order to clean it properly, but it did not yield immediate results. However, however a few days of rest and it came back to life, and has been stable since. So it looks like the rest is the best advice for other unfortunates.

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.
