Hello
I've ****ed up my sim reader by getting the sim card jammed in the sim tray -.-
So, instead of soldering a new card on to the mainboard flex, I desided to by me a new flex ribbon, and replace the old one.
The phone otherwise worked fine before, but after the replace of the ribbon it's now dead
What the f*** have I done?
Someone got an answer or good advise ??

How did you re-adhere the flex board to the motherboard??

First i heatet the board with a hair dryer, and then i was able to peel the flex of the motherboard.
Then i placed the new flex carefully on the connectors and heatet it up again.
But it simply doesnt work -.-

hi
i have a htc touch plus or as they call it htc touch dual.digitizer issue it stoped responding so i bought new one fitted in and still the same problem .i think is a software problem i guess driver software for touch screen .if any one can help please
thanks
Touch Dual digitizer
Hi Saliml2
Not convinced it is a software issue. My digitizer on T-Mobile Touch Plus did the same thing. It stated behaving erratically and then stopped responding altogether. I replaced the digitizer (via eBay) and it work for a few days and then stopped again.
I have read around the internet and have tried several ROM updates etc (currently running a WM 6.5.5 found in other area of this forum) but this has not solved the problem.
It seem to be an alignment issue - i.e. screen alignment is outside the screen area, but there seems to be no way of getting it back. Could be a fault on the phone mainboard (?) but there doesn't seem to be any info around apart from sending it to HTC for repair (not viable as the phone value negates this)
My phone is still not working, I might try opening it up again and reseating the digitizer cable but have done this twice already.
Have you try change the flex cable?
I had one to, with the same problem, and after changing the flex everything was ok...
Good luck!
Hi Amokh Just to clarify, what is the flex cable? The digitizer has a cable already attached to it that plugs in to a zif connector on the mainboard - I assume that this controls the data flow for the digitizer.
Any help would be appreciated.

My Connector for lcd is broken.. how can i get a new one?? any ideas??
if your connector is broken you need to a buy a new mainboard since HTC wont replace it.You can ask a local dealer if its available but here in india it isnt available..I dropped my phone and so i got a connector issue hence replaced the mainboard
no-wonder it overheats and shuts down under stress! look at all the **** down there
where to buy a mainboard ? any links or ebay ?
i coudlnt find any links to buy the mainboard so i bought it from HTC and its very expensive i paid 8000rupees i.e186$ approx in india

Hi arzin, can you tell where about the vibrator located at? is it easy to replace in your opinion?
Thanks..

Hello,
small up
The vibrator is just next to the flash, and it replaces easily
mainboard
Somebody tell me please the product number of European HD2 mainboard (NoT for US, they are different).
do we no anyone that supplies the main board yet, ???
Hello all.
While I was taking my HD2 apart to replace a cracked screen (glass digitizer) I accidentally broke the connector off one of the wires. The wire is black and a few inches long with a silver and round press on connector on each end. It attaches to the board that houses the vibrator motor and runs down the right side of the phone (if you were looking at it face down and partially disassembled).
Unfortunately, I lost the metal piece that broke off the wire (the thing is tiny!), so I can't just solder it back on. Any idea on where I can buy a replacement? I've spent about 6 hours today on ebay and google to no avail. Searching for "HD2 black wire" and anything similar is hardly efficient, but that's all I know about it.
Any help appreciated.
Thanks,
Chris
Good question, I think I damaged the cable to the volume buttons so it would be cool if someone has an adress where we can get spare parts except LCD and Digitizer..
this guy on ebay seems to be selling an HD2 in parts. you might find what you need here:
http://stores.ebay.co.uk/Right-Click-Enterprises/_i.html?_nkw=hd2&submit=Search&_sid=131407386
Thanks, I sent that guy a message and hopefully it'll work out.
Anyone else have a source?
connector of my hd2 is also broken HTC says that the mainboard must be change and I have to pay € 230 because that is my responsibility
I think you have damaged your coaxial cable connector for wifi and bluetooth. Google will help you perhaps.
I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
if the connectors on the boards are not broken then all you need is the coaxial cable with connectors on the two end. you need not disassemble the whole set, just open the back cover, connect one end of the cable to mother board and other end to the rigid flex board and that's it.
WiFi and Bluetooth not working

Do you think that this is my problem as since I dropped my HD2 I have no wifi (unless sat ontop of router) or bluetooth or fm radio, is it easy to get to the coax cable by removing back cover, whereabouts is it ?

Fixed it, opened up phone and spotted that at one end of the black wire the connector was not pushed onto the motherboard securely, I pushed it home and hey presto, wifi and Bluetooth now working, phew, Thanks for your help !

thx, for the information , I'm going to try ith a second time , but it's going to need some time cause I'm in Europe and the package comes from LA ,
so does anyone know wher i can get parts from broke down Atrix phones or somthing ?

friends my touch was working 50% so I tried some packing near front camera (may be fingerp sensor) area below battery as shown in another thread and 90% touch recoverd, but unfortunately the digitizer got torn and touch got unresponsive. I purchased touchpad locally in mumbai at rs850 but after fixing it was not responding. it seems that the flex cable as shown in above link looks bended.
Thus my question since the power module which is on the same flex cable works properly, is it still possible that the touch digitizer which also connects the same cable may not work. or something wrong with new touchpad (tried 2 of them). or some other problem at the junction on motherboard.
at present phone can power on, charge and pc connectivity only.
I dont have any technical knowledge, experts please give some advise.
thanks..
Hello,
A few weeks ago, I replaced my screen because my smartphone had fallen. When disconnecting the antenna cable, the coax connection on the PCB was broken. So I ordered a new PCB. However, with the new PCB, I no longer have any coverage. Is it possible that the PCB is not suitable for the European / Belgian network (GSM/Edge/3g/lte). I also noticed that the PCB I received differs a lot from the design that was in my smartphone. The PCB under the smartphone is the defective PCB, the mounted PCB is the PCB is the new PCB. You can find a picture here: https://imgur.com/Wzmq0p0 When my broken screen was still on the smartphone, I had full range and there was nothing wrong with the network. The connections of the cable is also not damaged: https://imgur.com/H4WkFmA Screenshot of no coverage, but SIM card data that is read: https://imgur.com/tkOhXI9 I tested 2 sim cards that I in the Pocophone. Both are from another provider. Neither got a signal. In my other smartphone, both SIM cards were connected to the network and worked as expected. Does somebody know if I ordered the wrong PCB foe Belgium?
Are you certain that the antenna cable is good?
If it's damaged the sim should show up but with no network at all. (Exactly the behavior that you're having)

The chips' small differences are normal between an aftermarket and an original imo

some blue resistor is missing in new one, i think!
The antenna was damaged a bit, but i also ordereda new one with the damaged one worked.
Because the antenna cable of the pocophone was out of stock, i ordered another one from xiaomi. It was a little bit longer but, still the same issue

In the pic it seems like the antenna cable is a bit smashed by the bezel when it was screwed together. You could try with another cable and test for signal before reassembling the phone.
I made 2 movies to show that there should be a difference and that the issue is not the antenna cable.
In this movie, I installed the new PCB and there is no networkconnectivity:

In this movie, I installed the PCB without COAX-connection for the antenna, but just tape. I'm using is now with tape for about 5 days:

Does anyone have an idea, where to fine the correct PCB to use in Belgium (Europe)?
I contacted the company, but they only say they buy it from "Iparts Buy".
Any help would be appreciated.
Did you ever get this issue resolved. I'm having the same problem
Hey
Here is a link to a trusted shop in Germany (mobiltec24). I can't post a link. I'm a new member.
I have the same problem as you. I am also looking for a solution. I buy a pocophone without mobilenetwork. I can't unlock the bootloader without SIM Card.
Having the same issue, any update ?
