Hermes totally dead.

Since I brought my jasjam it hasnt had a good life. It has been bashed around a bit too much and I only have myself to blame. This unfortunatly has cause the white screen of death getting worse and worse. Taking apart and reseating the ribbon cable to the board appeared to help but it would soon start getting worse again. The short term fix was a thump accros the palm of my hand. Unfortunatly today this back fired in me and now the phone is totally dead. I am fortunate enough to have another Jasjam that i was sorting out a few problems for a friend and this gave me the ability to swap out batteries chargers etc to try and get mine to fire up. No good.
I have taken it apart and checked all cables to no avail. pluggin in usb or charger have no affect. no lights no responce of anysort.
Any suggestions would be a great help
Thanks

That's too much of a challenge to answer - could be any number of things. Without testing it with a multimeter I couldn't say.
What surprises me is that your friend lets you anywhere near his phone - and does he know you use his bits to test out your poor maltreated Hermes
I assume you have looked through the service manual to seek any clues?

Thanks f0r you reply Mike
Im sure what he doesnt know wont hurt him anyway its only battery and charger.
Had a look thriough the service manual nothing jumps up and pokes me in the eye. I guess its fairly safe to say the main board has had it.
I cant seem to find anywhere to buy a replacment board and more importantly how much they are so i can see if its viable.
any suggestions

From my experience, you can only get motherboards from HTC or their repair outlets - this will cost lot$. Maybe if you're shelling out $$$ why not wait for the Kaiser?

please help my mate's dead Hermes
hi, this is to anyone who can help mainly prof and mikechannon. basically, i was trying to use my mates BRAND NEW hermes to repair my WLAN (Tmobile Hermes). it was working perfectly well until ran the RUU programme. i selected the 1.04SPL so that i could flash the hermes with the new NBH file i created. it flashed a 100% and it turned off and now its not coming back on. i plugged it into the charger, but no luck.i am afraid if i send it back to HTC, they might want to charge me for it. i love this phone badly, but sadly,i have given my mate mine. i dont mind sending this phone o anyone in the UK who can fix it. PLEASE HELP

I am not a flashing expert, so POF might be the first person to contact even if it's just to see if this is some recognised thing that can happen despite getting to 100%.
Can we assume the phone is completely dead? ie NO LEDs lit at all even when on charger?
Mike

reply for hermes (mikechannon)
yes it is totally dead. the LED only comes on RED when i take out the battery and stick in the charger.its not responding to anything. i have tried a HARD reset, no luck even a Soft reset too. i am now trying to use microsoft window CE 5 builder software, but i honestly dont think it will work. i really have to fix this phone. it a brand new phone.i tried ringing HTC europe but they are closed today. how can i check if its still under warranty. also, i bought it off some guy on ebay and just had it delivered this morning and now i have managed to brick it

Well I think you need to get a reply here or speak to one of the ROM gurus to see if this is a kniwn result of a faulty flash (seems odd to be but I'm no expert)
The phone is not completely dead if the RED led lights when the battey is out. It is meant to do this. Normally if the battey is faulty the LED will also go red when the battery is inserted.
Are you saying that when you put the battery in the Red LED goes out and no LEDs then show?
Mike

I had the same problem as well.
Red LED w/o battery, and NOTHING else.
Battery IN + charger : no LED
Anything else : no LED
Phone wouldnt boot
So I bought from eBay a broken 8525 that was reported to power up, but the screen was broken and some buttons were malfunctioning before the screen broke.
Swapped the motherboards and now I got a functional 8525.

yes, mikechannon, thats excatly what i am saying. when the battery is out and the charger is in, the RED LED comes on. but when the battery and the charger is in, nothing happens

I would have been tempted to say to check with another battery in case it was therefore a battery fault. BUT given what alkizmo says above it suggests the issue is as likely to be a blown component on the m/board. The Service Manual Hermes or Wizard ( I forget which) refers to a fuse. However nobody so far has identified a fuse as such. It may be another component (resistor perhaps) that is used to blow if current is exceeded. At present though we do not have sufficient info to either identify this component or bypass it.
Still think it's worth a casual inquiry to the ROM gurus to hear their view on whether this is hard or software related.

Hermes Dead Battery ??
The Red Light Will Not Work If The Charge Is More Than 50 Per Cent
So Try To Shutdown Your Hermes And Put The Usb Charger Then Reboot Your Hermes
May Be It Will Work

Having experienced blown motherboards on a laptop, a desktop and now a cellphone, I can attest to this : If NOTHING powers on at ALL, it is a hardware fault. Before you speak out for laptop/deskop, don't forget about the BIOS, if the BIOS is fried, the motherboard will still power up (fans spinning, lights turning on).
However, maybe that something in the software CAUSED the hardware issue. However, once the damage is done, no changes to the software (even if you could change the software without turning on the phone) would make a difference.

The red light shows when there is no battery as well and the charger is plugged, if there is no battery and the red light doesnt show, you got a problem.
And, shutting down/rebooting is not an option here. The guy's phone won't even light up. It's fried.
Last suggestion of hope : remove the battery and leave the phone unplugged for a whole day. Then put back the battery and do a hard reset attempt.
If this doesnt work, then I got nothing else, as I said, I resulted in replacing the motherboard.

if you cant get it working i will buy the back speaker off you

ok, i am an optimistic person so i will surely try your approach. one question though, as the phone is brand new, do you reckon if i send it back to HTC europe, can they fix it as it is still under warranty?

thanks a lot for your reply. i am an Optimist so i will surely give your method a try. one question though: do you reckon if i send it back to HTC europe, will they fix it as the phone is brand new and still under warranty.although, i bought the phone on ebay brand new from a seller for my mate.its a vodafone branded HTC. cheers

Usually, most companies only warranty items from authorized dealers. If the seller was an authorized dealer you are ok. If not, they "might" fix it. Call to make sure before sending it in.

Dead Hermes
My VPA Compact III v1605 seems to have the same type of problem - it only shows red lite when it is plugged in and battery is off, but... but I can also (hardly) recognise 4-colour bootloader-type screen, which blinks once and reappears every time I reset the device.
It doesn't communicate with computer, MTTY says "USB port can not open"...
The difference between usual bootloader screen and this one is that I can't recognise any characters (like IPL/SPL), or maybe because it's hardly seen, I can not see characters?..
Is there any chance to have this device repaired?

Ok, not sure I can help here, but first can we clarify something -
You say the red LED shows with the batter "off". Do you mean with the battery out of the phone?
Mike

Hi there,
i messed around a lot with the hermes hardware the last few weeks.
There's a lot of stuff in those mobile that could go wrong

Seems like there's some part messed up in hardware.
If you dropped it some times, maybe some component got damaged.
Please check the voltages on board firmly after pressing the power on button with battery inserted. Just like mikeshannon suggested
There have to 3.15V, 1.8v, and ~1.2V around the board.
I will take a picture from the mainboard with testpoints if you like.
Anyway you need some electric skills
Otherwise give to a service center or buy a new mainboard.

This is very similar to what happened to my device. After downgrading from olipro's hard-spl something went wrong. After flashing succeeded with 100% the device got restarted and there it was... nothing!!
What i found out in the meantime is that the IPL was not flashed correctly.
While trying to reflash the device with JTAG debugger, i examined that the NAND write protect signal sticks to GND right after reset.
Maybe this also a hardware issue. I'll find out soon
The bricked IPL-bootloader could also be the cause.
At least if the red light turns on, the DC-DC converter on the hermes is doing well. This means the unit is partially working but not booting.
....nearly forgot to say, that there is also a fuse on the hermes mainboard.
should do some pix

8525 dead after program removed!!!

I was removing iGuidance v3 and in the middle of it, the phone turned off. Thought I just hit the power button to turn off screen and press power again. Nothing. Thinking it just crashed, I held down power button, nothing; removed battery and replaced it and hit power, nothing. Put it on the charger and it doesnt have any lights showing its charging.
The phone is less than 6 months old, could it be the battery? What should I do? any help here appreciated.

Have you tried a reset press and hold both the side OK button and the power button and then press the reset button by putting the stylus into the hole in the bottom of the device.? This takes sometimes more try's.
Now do a soft reset (again put your stylus in the hole on the bottom of the device, dont press any other buttons).
Mostly this should do the trick!

Ok, replaced battery today and still no power nor charge. So how do I reset? Hold power and ok button down and then replace stylus in hole? Do you mean the ok button on the side or on the front?

You may want to do a HARD reset, not a soft one.

Tried hard and soft resets by putting stylus in pin hole. No luck, think its toast. Also tried the battery in/battery out trick while on charge.
Ive heard of phones crashing or being bricked after a bad rom install or taking off usb too soon, but removing a program and it dying is different. Never had any issues with this phone. Is there a way to test it w/ a multimeter to see if mobo is bad?

What about replacing the little round battery thats on the mainboard? Would that do anything?

Isn't it still covered under warranty? If so, just have them fix or replace it bro.

No warranty. Replaced the screen myself a long time ago.

I just got an email from HTC telling me basically how to preform a hard reset. Well it didnt work. My phone is a paper weight now. Ive never had to do a hard reset before. Used Memaid to do the soft reset all the time. Ill keep trying and fix it eventually by either replacing the mainboard or digging deeper for a fix. Thanks for help everyone

Just got an email from HTC help:

HTC America CSR"
I called the number for troubleshooting first and was told that this isnt a fix that anyone can do on their own. It must be sent in for further analysis. What was interesting about the conversation is when I asked if he had ever heard of this problem before. He said he gets that problem all the time with these models. Ive never of this happening. Never found any other posts about it either. I bet its a problem with the phone holding a charge on the mainboard, like a faulty capacitor most likely its gonna have to be j-tagged at the repair center.

Hi
I don't think this is a very common problem as they say. Yes, there are many reports of the failing to charge issue and stuck on the red LED light, but only a tiny number of absolutely dead devices.
Curiously, the service manual refers to an on-board fuse. But later states that when this is blown that those without board level repair authority should "replace the m/board". Clearly then, this is either not a fuse in the ordinary sense of the word or refers to any component that may be "blown" and would require detailed tests to track the problem.
Just for info: the m/board is not a basic simple one in terms of soldering / component removal and replacement. Speaking personally, I would not attempt anything more than very basic work on this board - perhaps just on some of the "cruder" connections here and there. Boards in these types of phone make the more typical boards in other electrical equipment look like ironmongery.
Mike

Ive examined the mainboard and looked it over very carefully for any burnt resistors or capacitors. Nothing out of the ordinary. The components would be a huge project to replace, their soooo small, only the mini USB charger port could actually be done by hand.
What would the fuse look like? Is it soldered to the board? I see a small round battery near the PTT button. Is this something that can be replaced? Probably messes up the BIOS when removed like a computer motherboard.
I shouldnt have been so quick to sell off my Wizard before this happened.

often fuses are no longer used, they use a for example 1 Ohm resistor of limited power rating instead.
You might try to follow the current on the mobo while the charger is connected, see whether you can locate the disconnecting (faulty) part.....but the size of the components makes this a very difficult job....my gues would be that the problem is located near the power entry/regulator if nothing goes, meaning no action while on battery nor w the charger connected.

But these are multi-layered boards, it will be very hard to trace a connection on it.

Ok, so I lost my motherboard. Probably something killed it during the whole uninstall process. Made peace w/ that. Maybe bury it in the backyard or something. LOL
I bought it to replace my aging 8125, but wonder if I did it for the wrong reason. I thought the new processor would be way faster, but it really wasnt that fast. 8525 has a nicer housing, camera and 3G (which i never used), A2DP that doesnt skip. Never even used the pre-installed programs like Mobi-TV, Telenav, etc.
Anyways, anyone think a 8125 motherboard will fit in a 8525 housing?

Vibrant T959 Only Turns On With Charger Connected

I have a Samsung Vibrant T959 TMobile US with 2.1-update1, Baseband T959UVJI6.
The battery is fully charged, it registers in the phone as fully charged 100%, but when I hit the power button I get a progess wheel that gets stuck, then the phone just turns off. It never gets passed that wheel, it only displays for a second then dies.
However, when I plug in the USB and hit the power button, it comes right up like it should. Then I can unplug the usb and use the phone just fine. Its almost as if I need to jump-start the phone with a power source.
I have reset the phone, even re-flashed the stock firmware using Odin. Same results. I have even swapped batteries with a buddy just to see if that was the case, but I still got the same results.
Any advice or suggestions is GREATLY appreciated. Thanks Very Much In Advance!

Anybody? Any ideas?

Well, that is new to me...
I'll preface with, I have no clue how/why that is happening. But, this is what I would do:
1 - If really opposed to rooting, I'd call T-Mo / Samsung and get a replacement.
2 - If I liked my phone and wanted to make it better, I'd root it and flash a custom ROM. It likely would take care of the issue, as it clearly is not a hardware thing (well, I say clearly).
Worst case with #2, ODIN back to stock and then do option 1.

possible solution
also it says "USB connected" even when cable is unplugged? I had similar problem.. I tried everything, flashing, changing batteries.. none of that was useful. Then I find some post on some forum that says it might be corrosion, so i scratched my USB with thin wire and everything worked fine, but also scratching USB I was doing one more thing. In my opinion, I think that it's not corrosion. I think that USB is slightly bent (middle part of it), try to bent it in other direction, possible that it's too close to edge. That solved my problem. Tell me if this helpful for you, sorry about my english

i think i can get what you are saying, cleaning the usb port on the phone right??
BUT how does this affect turning the phone on?? if usb port is rusty, it will only affect charging, not turning the power on?

I experienced this identical issue last fall -- the USB would always say it was connected, wouldn't startup unless connected to actual USB, but otherwise worked fine.
Take your phone apart and look at the solder joints on your microUSB port... mine all had cracks in them or had broken free. I re-flowed the solder while holding the port down and it resolved my issues. (put on some flux, and run a hot soldering iron across the joints, clean up... it's not very difficult. just be sure you don't short out any of the pins.) I also added additional solder to the four points that just hold the mircoUSB to the circuit board. It's been rock solid since

See if there is a TV or electronic repair place still in business in your area. Or post an ad on CL asking someone with knowledge and skill to do it. Be careful they aren't an idiot just wanting 20 bucks and happen to own a soldering iron.

you could see if Cell Phone Repair/ is near you and describe to them what you want to do.

I would go through these guys they are top notch helped me when i soft bricked my wife's phone. He even convinced me that i could fix it myself when i was ready to send it to them for a jtag.
They can replace the usb plug if thats the issue.

I would test to see if my battery is bad first before i went about resoldering, it could easily be a bad battery.

SK4G Hacks

There are two hacks I want to do to my Sidekick 4g. First I want to swap the volume buttons and the charging port, cause its kind of a dumb layout and I end up hitting the volume buttons all the time. Also I would like to use docking stations and cant with the charger on the top of the phone. Second I want to add a flash to the camera. I don't know why they didn't include one it makes no sense. Any ideas? If there are any other interesting hacks you want to do or have done tell me about them. I will post pictures as soon as I get things all moved around.

I found a complete teardown of a SK4G on here so I'll use that as a atarting point. My dad knows electronics so he said he will give me a hand. I am currently searching Ebay for a second handset so I'm not tearing apart my daily driver for hacks. I will post all steps I take for everything, but I am still looking for advice from anyone who knows more about the SK4G.

I think the flash is going to be really difficult. The flash I think uses a big cap to charge and then discharges it into the flash element. The problem is first getting the synchronization, too soon or too late and it is moot. Tying it to the button might work but you might need to insert a short delay (more electronics and room).
Moving connectors is probably the easiest to do. Really you need to remove the one from the board, solder some connections and run it to the new place. Routing the wire might be challenging because of the limited room but should be possible. The volume is going to be a comparable challenge, the buttons are likely on the board and very small but once you get them off all you have to do is wire them.

Thank you Giritrobbins! I didn't know that cell phones needed the flash cap too, I thought it was just an led. That will slow things down some but that saved me a unneeded headache.

Resurrect a dead M8, mate?

Hello,
I acquired an HTC one M9 to replace my dead M8 that I caused (funny story at the end). The headphone jack was wonky, and since I had disassembled and reassembled an iPhone 4S in the past I thought I could try my hand at this. The hardest part was getting the M8 out of its metal shell, and I think that's when I may have damaged something. I was able tot get it back together, but it will not power on.
I can plug it in to a charger and I see the screen come on showing that it charges and that there is a healthy power level to begin with. I can no longer find the plastic power button though, so I have to use a screwdriver tip or a spudger to press the sensor to turn it on. I've held it down for 30 seconds, 1 min, held it and the volume down button for the same amount of time, and tried the same with the volume up button, but no luck. I keep the shell off of it when I attempt to revive it, if that makes a difference (slightly easier to reach the power on button at the top). I can possibly put it back in the metal case and try to hold down all three buttons, but it's a ***** to get back out of the case.
I remember reading a few threads here or elsewhere regarding the ability to jump start a dead phone or android device, perhaps it was a Nexus 7. Is there anything like that in the development package or a standalone program where I can connect it via USB and jump start it that way? Or is it pretty much toast at this point? I see replacement power buttons and power button boards on eBay for under $20, but with my (lack of) skills I believe I'll just damage it more. What are your thought and what are my options?
(Funny story). I purchased my HTC One M8 from an eBay seller, yet when I got it, the power button was not on top but on the right. I'm thinking, "okay, didnt know I'll have to start looking for alternate M8 cases...". When I called Sprint to activate it and provided the information, they said it was actually an M9! So the reviews aren't as favorable towards the M9 as they are the M8, but I love it nonetheless. And of course if anything needs replaced I'm just going to take it to a brick-and-mortar shop to have them do it, save my spudgers for working on laptops.
Thank you for the help and advice!

Unbelievable i pretty much have the same problem since yesterday.
Ok i try to write this as short as possible.
My Headphone Jack was also broken so i bought a new USB/HJ/MIC part.
After putting it in i wasnt able to load my phone anymore with the new piece so i tried back the original one with the dead HJ and it worked again. So i let it inside, contacted the seller to send me a new one. Which is not here yet, but he doesnt want the first one he sent me back, which is quite fortunate.
However yesterday i dropped my phone on high grass - it was completely dead so i couldnt call it using another phone thus i wasnt able to find it for like 1hour, it was dark, and very cold(-2°C) and also wet and i think this is how i broke my M8. But im not sure yet. I used a flashlight and apparently found it after some help of a friendly lady.
When i was back home it didnt start. Not even when charging. Then i thought myself i will try the new part again with the "broken" USB Jack and pretty funny it somehow works. BUT: Charging it turns on the screen instantly, gets me into recovery (always did that, never startet directly into CM13 which is use) but after like 15seconds it just turns off and starts again, showing me the dead battery icon at first, then the recovery. Im not able to turn it on using the power button (didnt loose mine ) it just turns it off because it starts by itself when chagrer is plugged in. I dont know what to do now: i dont have enough time inside my recovery (CWM) to reset it or something and im not really sure if it is a software or hardware problem but i speculated its the battery which is broken now. (?) However when i put the charger in to make it start, then pull it is able to hold itself for the same duration as if i was charging, but only sometimes. This really confuses me.
I dont think i broke mine during the repetetive change of the part, but im not able to exclude it in my troubleshooting. I know i didnt help you at all probably i just wanted to share my very same problem because no one else responded and i might also get help.
