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:

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.

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?
I just bought a replacement power button/ flex cable for Nexus of ebay. Took me around 30 minutes to replace it but its fully working right now. Its around 30 £ .
Item name it "Flex Cable Repair Parts for HTC Google Nexus one G5 1"
Just thought i let you know .
Any pictures?
Is it a tricky fix? I replaced my digitizer just fine so hopefully this wouldn't be a major repair job in comparison. Would love to have my power button working again!
I don't understand why you fixed it yourself, I sent mine back to HTC.

How much did it cost for the repair out of interest? Did it take them long to get it back to you?
Just curious if to you it looked like a bad button connection or a bad cable? I know sometimes the buttons get crud in them so they dont make a proper connection...
Great info. Too bad we don't have step by step pics. How did you take the phone apart and how deep did you have to go?
Does anyone know why the power button breaks? I have my N1 a year now and (luckily) i never had a HW issue. anyways i was just wondering why it breaks .
Step by step pics would have been nice.

The power button itself has a small cylindrical piece of plastic which pushes against and presses a small connection that sorta clicks (Which gives you the tactile feedback you feel). I think the problem occurs when either 1) The piece of plastic either bends/breaks/gets damaged in some way that makes that contact much harder to produce 2) The connection is connected to the phone via a cable/flex, however due to the Nexus one design it is bent around in order to be below the power button, while this is fine for the majority some devices, including mine, have seen the flex become damaged for whatever reason and either function intermittently or not at all.
It's also interesting to note that there is nothing holding the flex or the connection in place except for the design itself i.e. the battery bay plastic holds it all in place. My power button was never that responsive (But got progressively worse) so this may explain why.
Its always flex cable breaks and there is no way you can replace just the flex cable.You can find plenty of disassembly instruction over the net and yes you need to disassembly it to the pieces( still less to do than to replace digitizer.)I had a seal broken so i couldn't send it to HTC.

I did some googling and found a few images of that component, I remember taking it out and it was pretty simple so it should be just fine! Thanks for the info!
Is it the Power button part that you changed ?
Hi,
I have found a photo of the power button part, can you tell us if you changed the full part shown on the photo ?
androidguys.com/2010/09/08/manage-nexus-broken-power-button
And i think you paid it way too much expensive ?
Thanks.
I just replaced my flex cable as well as the loud speaker as well.
iFixit has a few pictures and there is a video on youtube, of the taking apart process. Unfortunately I can't post links
There are two little rubber parts that will likely fall out during the mainboard removal. One goes underneath the connector beside the sim card and one is a part of the microphon.
I wish I could have taken pictures of where those parts go, but alas, my only camera right now is my nexus, so....
BTW, I bought my parts at Mobile Brando. Quite well priced as compared to many other stores of the kind.
was it the whole board that you've replaced? or just the flex cable for the power button. can you further elaborate the steps that you've done?
So this is the item that you purchased? http://mobile.brando.com/google-nexus-one-mother-board-flex-cable-ribbon_p6193c1023d88.html
Can you confirm that the 3.5mm jack is on that board? Additionally, is that motherboard and flex cable for the AMOLED version or the SLCD version?
Do you need to remove the screen and risk getting dust inside there to swap this part?
Hi,
That's exactly the item, at that very same store. I also bought a loudspeaker as well as both back covers there. The audiojack is on board and I believe the flex cable has nothing to do with the screen type. The screen does not have to be removed.
I used those pics: http://www.ifixit.com/Teardown/Nexus-One-Teardown/1654/1
and this video: http://www.youtube.com/watch?v=cznogushN34&feature=player_embedded to figure out how to do it.
Basically, it's quite straight forward, given that you aren't a clumsy oaf ;-)
Remember the two rubber parts that might fall out when you pull off the mainboard assembly. (one at the bottom, for the microphon (http://guide-images.ifixit.net/igi/fpRmPyN6h12mtNvt.huge ,a bit to the left of the plastic tool) and one at the connector beside the sim card (http://guide-images.ifixit.net/igi/EOfeocuwhCRASB6M.huge , on the left part, somewhat down from the serial number sticker).
I have this probleme, but this part costs too much :S....
10. pin ON OFF way in board socket... u make jumper to on off buton
I have replace Power button for my N1. But you can reset your N1 by do'n need it. Except when you want flash rom!
Hello! do not work volume keys and may not enter into bootloader, operating system does not loaded, tried to rearrange the firmware and then it gives an error that this firmware is not compatible for this version of the hardware device. Cable with side volume keys is work! the problem with the motherboard, how to install the OS on this device? I would be very grateful for the help!
i guess you have to have your HD2 repaired first as the software is dependent on a good working hardware.
Can anyone knows how to cause butloader without side volume keys? or can someone already had this problem and knows how to solve it, please share experiences
Well, i guess you can take apart the HD2 and then try to start it into bootloader mode by prying off the volume tape/contact dome from the volume down contact and then shorting it with a piece of metal...
I tried to remove the cable and multimeter test button and cable, they were working, the problem is on the board

It is also possible to be a faulty connector on motherboard or even some contact on main flex ribbon in same connector area.
yup ask someone who can open the device to check it
He is now in the the best master of our small town. I think that on Saturday when it will take will still try to disassemble and repair, I will write here on Saturday. Thank you all!
Alright guys,
I already posted into the Android Q&A Thread because I thought it's Android related but it's not.
So I'm posting here again.
My power button drives me crazy .. I'll explain it in detail.
I can't turn my phone on using the power button, only by putting the battery out and in while connected to the charger.
BUT the power button works flawlessly after the phone started.
I tried 2 different android roms (gingerbread & jelly bean) and the stock wm 6.5 rom.
same result so far.
I can turn the phone on recently after powering it off using the power button.
just if I wait a few minutes and let it "cool down" it's not powering on anymore.
could this be related to any elecricity that's gone in the meantime?
checked the pins and they aren't bend. battery charges fine too.
I'm out of ideas so I hope someone is being able to help me.
Has Same Problems
It might be mainboard so need jtag ti rebuild checksume
Sent from my HTC Desire S using xda app-developers app
uhh I hope not.
don't know anyone who'd be able to do jtag for me
ok .. this is .. how should I explain it .. STRANGE!!!!
just tried to power on my phone using the power button as usual .. no effect.
I put the phone on my radiator for 3-4 minutes just to see if it makes any differences with a certain temperature.
and it's powering on again.
so the problem is the HD2 not having this exact temperature after being shut down for several minutes
WTF??
Hardware issue.
Maybe button board, mainboard. When it's at certain temp circuit/component working, when at lower temp circuit open/component failure.
Worth checking battery pins again for straight & cleanness & also perhaps another battery if possible just to rule it out fully ...
thanks for the reply.
I tried 3 different batteries so I doubt that's the case.
checked the pins again and they aren't bend or corrosion on it.
too bad I can't check the mainboard again or even replace it.
had to replace the touchscreen / digitizer and when I try to open the HD2 again now they both would separate from each other.
got another question.
is it possible to open up the HD2 without the problem of the digitizer and touchscreen separating from each other?
I'm not able to change the motherboard if so.
If assembled correctly centre chassis, LCD & Digi come out as one unit bonded in layers.
I assume your bonding of digi, lcd is not the best hence easy parting on first stage of lifting chassis from casing. Problem is all but the very best industrial strength tape is all but useless, I use pu40 adhesive spotted in high lift areas & near edges so easily freed for future strip & best tape I can find for the rest
If layers separate you would need to take great care not to put load onto the flex cables.
I would recommend reading the repair guides & videos again as bad technique will not help & simple point of pushing lightly on build sticker can make first removal step much easier.
Good motherboards are hard to find at worthwhile cost ...
the digitizer and touchscreen have already been replaced by me. it's been an already soldered version from Taiwan. Seems the glue used to fit digitizer and touchscreen together is as you already stated not the best.
I'll just bear with it and sell the HD2 for some low money. this phone drove me up the wall too often.

Is it possible to use a key map app to remap this key? and you will see what kind of problems it have(hardware of software).
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.
