Yes the eMMC Chip, but I don't know what part to buy.... I am not in a rush because I have a HTC Sensation and want to use the MT4G as a backup phone and I don't want to pay $ 185 for repair with HTC.....
The chip is soldered to the motherboard. Did the chip die? If not, don't worry about it.
If its dead, well, get a mobo and start desoldering buddy....
Another alternative would be to get a phone with a broken screen and mix and match parts to make one complete phone.

So I bought a digitizer replacement kit on ebay for my N1. (I dropped it and my screen shattered.) I saw the iFixit teardown on the N1 and figured it'd be easy enough to do myself. The kit comes with tools to open it, but no adhesive to mount the new digitizer.(like the iPhone kits)
Basically I was just wondering what I should use to stick the new digitizer back in. Any advice from someone who's already done it would be great too.
Edit: Got the digitizer installed fine, phone booted, I giggled like a schoolgirl aaaand.. Couldn't unlock my phone. It wont respond to touch. Took it apart again to make sure it was connected properly... So now my only assumption is the digitizer I bought was defective.
Any help would be appreciated..
try asking the ebay seller
Thanks, I'll try that. Any other ideas?
maybe ask an electronics repair shop near you

Well I got it installed but it wont respond to touch.. Defective part?
I guess you've made sure it's plugged in right? Would definitely double check that

Yep I did. I contacted the seller on eBay and waiting for a reply. Unless you guys can think of something else I did wrong in the installation I'm sticking with it being defective.
have other people replaced the digitizer successfully on the N1? or perhaps it is some software difference that the new digitizer needs to be "read" by the software, but the OS is looking for the "old" digitizer still...i'm talking out my arse BTW..

I've seen a few people posting here saying they've done it, and I know one guy took pictures of the process. I understand what you're saying and it sounds logical enough, but I can't imagine the parts would be any different to cause that sort of problem.. Assuming the part I bought is legit.
Either way the seller should let me return it if the second one they ship out doesn't work.
i replaced my screen and digitizer yesterday using ebay tutorials i found. pm me and ill share but i bet you used the same ones. its a very delicate process. sometimes you have to be tough with it but at the same time not break the little guy. the only problem i could think of would be your connection. the only thing i fudged on minr was not cleaning the lcd before placing it back in. now i have two large fingerprints in my top right under my screen when i dim it.

I believe I have the correct adhesive (3M double-sided sticky tape of some small sort), but I'm wondering if anyone has a better idea on how to get the old sticky gunk off of the LCD aside from using rubbing alcohol? Thoughts? Kthxbai.
EDIT: Also, did you ever get your phone working again?
Hello.
The MicroUSB platform on the main-board of my HTC HD2, is broken. So I can't charge the phone nor transfer files.
I disassembled the phone and I need a new main-board now. The part number is 76H03923-XXM.
Where can I buy this part? I've contacted HTC a week ago, but still no answer.
If anyone have this part for sale, please contact me. Or if anyone have a broken HD2 (maybe broken screen), and wants to sell it then don't hesitate to contact me.

Damn so it seams it wasn't only me that happend that. So did i broke my USG port and my phone does not charge. Plus went to the official reparement and they do not want to take responsability for it. They came with the vague excuse of "mainboard defect not covered by the warranty".
They showed me a photo of the board and as they saying my phone has humitty there for not there responsability...
I also wanted to buy a mainboard for my phone but i've searched everywhere and no luck.

To begin with, I sent mine for repair too. HTC wont take the responsibility for the phones broken USB port. They only sent me this picture showing the broken USB.
I haven't treated my phone bad, so i was very disagree with their decision. But they only gave me a link to the Danish court of appeal.
- So, what have you done now? Bought a new phone?
It's sad

To me they came with the lane excuse of humitity in the board. I see that everything is a good excuse not to take responsability for theye'r crappy materials...
I've always been afraid of something like this happening. That's why as soon as I found out powermat made wireless charging for the HD2 I ordered it. It really sucks for everything to depend on one little port.
You might try this solution for now and just use wifi to transfer files. It makes flashing tough but at least it'll be working, and you can take your time looking for a new board.

I got exactly the same answer. "Humility on the board", it would cost me 550$ for HTC to change the Main-board.

I already have seen powermat buy can't buy it. I live in Denmark and they don't ship over here...

Nothing there

Damn $550? Thats a new phone... They asked me €180 and i though they were crasy lolol. The 2nd battery n the charger for it i have one what really needed is something to replace the USB connection...

Can ask them on the part# for them to search.
Similar problem here. The Micro USB doesn't get inserted properly, seems like it's sticking out a mm too much, resulting in a very bad connection, whereas a few month ago the micro usb would stick in completely.
It now only charges, transfering content with a pc isn't possible anymore.
My thoughts were: if I buy a cradle, chances are that it would connect better due to the gravity (don't laugh ). Today I received the cradle but no result. It only charges, and I have a feeling the charging will stop in the near future.
I have the HTC HD2 for exactly two years and I found it very frustrating being confronted with what is in my thought a construction problem.
I've seen the link for dealxtreme, the external loader, but the comment posted below it, doesn't really encourage me to buy the item (high temperature)
Any other thoughts would be appreciated.
If you know anyone that can solder. They can detach it, and re solder it back onto the main-board. Shouldn't be too hard. I think? Should be possible.
Might help out some of you who have the same issues like I did. I used a toothpick to remove dust from the micro usb port. Although the connector still doesn't fit entirely, I now am able to transfer files again to my phone using the cable. Connenction still isn't that good, but might help.
htc broken port
Dear all. If you experience problems with changing your connector i can help.I have the equipment and will do the job for 20$ only (the price includes the brand new connector) Only problem is that you must ship it to Bulgaria so i can do the job. If anyone is interested can pm me.

Is there a way to change the partition size witout USB?
EDIT: Is it possible to feed the power directly to the battery connector, and if so how? I could solder a simple circuit if this would be necessary to use a USB adapter as power source
Micro-USB
How can I change myself my micro-usb (for HTC HD2) . Are there a tutorial ? or any videos ? Where could I find all accessories and components required for the repair?
I think the accessories will cost more than a new HD2... I think you can´t do it by yourself because its to tiny
Bad idea!

hi, i bought a hd2 off eBay and the guy i bought it off had tried to install android on the NAND memory and it now wont turn on. i have tried the hard reset, the phone will vibrate once when you press the power button then go to a clear screen, like the back-light is just on i need help urgently.
Sorry if this is a dumb question, but have you tried powering on while holding the volume down button?

If you can not get to the bootloader by holding down the volume down button while powering on then the HD2 is bricmed and will ha e to have a JTAG used on it or replace the mainboard. Sorry friend but it sounds like the guy you bought it from new this when he sold it.
You're best off disputing it on eBay and trying to get your money back as to JTAG a device is a complicated procedure. He probably flashed a bad radio which lead to the phone dying (not battery).

Same problem here - fortunately, I've still got access to the bootloader
If you can't get into the HSPL bootloader by holding the volume control down, so that you can reflash the NAND ROM then I would dispute via eBay. Especially if the ad showed the HD2 to be operating correctly.
i bought the phone as is because the guy i bought it off read somewhere it can be fixed he couldn't understand how to do it and apparently yo can take out the nand memory and put a working one in.

My knowledge of ebay rules & regs isn't great, but from the sounds of it the guy's done nothing wrong. If he sold it to you having stated that a component needed replacing and that it was sold 'as-is' then I imagine you've got no comeback. Have you looked into the problem yourself? (ie how much to change the mobo on an hd2?)
Sorry dude, but I think this is one of those 'learn from' mistakes. Hopefully you didn't pay much or can at least sell it on in the same condition...

Sorry but like I said before the only two ways to fix a bricked HD2 like you have is to use a JTAG on it or replace tbe intior mainboard. The NAND chip is not replacable as it is secured by a hard opoxy that requires a very higb temperature to melt and this will ruin the CPU and the intior mainboard. Go to the thread I linked below and read you will seewhat I mean.

+1. JTAG is most likely your only logical shot here. Not many do it, I do this for HD2's but I see you not in the US and may not want to send it to me. Good luck with whatever you decide!
My big bulky phone with the big bulky extended battery dropped to the floor as I got up from my chair, not realising that the usb cord had decided to entangle me. Next thing I know, my precious hd2 is lying on the floor, screen faced down, and the usb cord "ripped".
Everything seemed to be working fine, but when I tried plugging it into my dock, it wouldn't charge, so I tried holding it at angles - it worked, but whenever i let go, it would stop charging.
Does anyone know how to fix this without having to take the whole thing apart?
Sorry friend but you will have to take the phone apart to fix this problem. Might even have to replacecthe mainbosrd as the USB port is attachedcto the mainboard and can not be replaced seperately.

I was really hoping not to hear that .... but ty for the reply, I'm just going to go to the side and sob for a bit because I can't afford to get mobo replaced, I can't afford much right nw.
As a temporary solution you could buy a wall charger and an extra battery off ebay for a couple of bucks, changing and charging batteries on the go works for me!

ty, but I'm worried that it'll get worse in the long term (long being anything over a couple of days), ie. completely stop working, and data transfer? I'd have to use wireless adb to do transferring.

I looked at the warranty terms and conditions, and it says that anything that has to do with the usb port area will not be considered as being part of the warranty, and I don't have the receipt because I got it 2nd hand. :'(
it could be fixed, but the port must be resoldered to the motherboard. In case some circuit tracks were broken in the incident, they will have to be remade, a good service center could handle it.
Most of them aren't too fond of using real electronic measurements and algorithms in order to track corresponding usb port pins to various points on the motherboard but it's not impossible. If my hd2 would have been damaged in this way i won't hesitate to crack it open and get my hands dirty
If I wanted to, how much do you think I'd be able to sell it for? Thinking of selling it, and mybe getting a used tmous, if I can afford it.
I've managed to find some tmous on sale, so, what do you guys reckon I could sell mine for?
When I broke my first LEO512 by thinking I could repair it, I took the individual components (Case, chassis, motherboard) out and sold them on ebay. I got about £119 in total for it all
You could always sell it for full price and let the buyer find out themselves what's wrong with it.

I have this problem my micro usb port has completely broke, and the circuit lines on the mother board are screwed up, HTC will not touch it
gone the route of a wall charger for now came with another battery for £8 delivered so im happy i can still use my phone, while looking on Evilbay for a new hd2

Finally had the courage to open it, and as you said, the connections are more or less broken off, and I've got shaky hands (without nerves) and can't handle soldering it, so I'm thinking of patching it up with some blue tack

hi T-macgnolia ....(dont take this as an argument... just curious ) i just saw a replacement micro usb port for hd2 on ebay.... so is that usb port on ebay just to fool us or can it actually be replaced
Ok, short story - nt gnna work, does anyone have the bottom part of the motherboard up for sale?
Just got even better, looks like the lcd's broken now
Maybe someone can help me. I have a T-Mo HD2. I sent it in to HTC's repair center, while in repair they damaged it and the Camera/Volume Up no longer function. HTC won't repair it (It's a long story.) Anyway, since I've been fighting with HTC for weeks now, and getting nowhere... What could they have possibly screwed up internally so I can look into replacing it myself?

1. they HAVE to repair it when they damage it
2. in good case the buttons are damaged which you can replace if you disamble the phone
in bad case, they damaged the mainboard, so your hd2 is a brick
