Guys,
I read the user manual and found out that the antenna location in the HD is actually in the rear part of the HD instead of the upper part. And there is a warning in the manual not to touch that antenna location while using the phone.
So, how would you hold the phone while talking and not to touch that antenna location?
Second question, about the speaker.
It seems to me that the only speaker location is the front (the ear piece).
Is this right? I have a Prophet and it has a small speaker (ear piece) and another one in the back for "speaker" mode. I prefer it just in the front (same design like the old Wallaby etc).
Is this the case with the HD?
I've tried and you can't help but hold it the same way you would hold any touch sensitive phone...
There is a speaker next to the rear camera. It's small, but it does the job. Unless you're expecting cinema-quality, of course, lol!
See the attached pic taken from the HD User Manual.
antenna is in the bottom on the Diamond and Touch pro aswell...its this way in a lot of newer phones.
i need a main camera for my htc tytn ii as well as pfc connector ribbon as my camera is dead as well as pfc connector ribbon has been damaged due to frequent use of sliding of hardware keyboard.
please suggest from where i can buy it.
my location is delhi, india
After replacing the main board of my HD2, the keypad no longer works. At first the button on the left (answer phone) was still working while the other weren't but after reseating the flex cable of the keypad, none of the keys work.
I don't think the main board (or the connector) is broken but I will be able to test that soon enough since I ordered a replacement keypad board. I will be able to just plug that one in without having to disassemble the HD2 to check if it's indeed the keypad that's broken.
But if the keypad is indeed broken, I will need to replace it (obviously). I can find how to disassemble the HD2 (video's, pictorials, etc), but nowhere can I find how to assemble the HD2.
For instance, you will need to separate the screen from the chassis by heating it up (with a heatgun or blow dryer) since those are glued/taped together. But I can't find anywhere how to glue/tape those two parts together again.
So can anyone direct me to some instructions? Or have any tips?
(Shameless) Bump?

Thanks for sharing unfortunately the eink display parts are out of stock.
Any other ideas ?
The glass on the back is cracked, though the actual epd panel is working fine.
Also price ($78) seems crazy for a rear glass when the whole phone was only $110
Since I've purchased the Joying JY-UQD11N6G (aka JY-UQD11N4G but with 6GB RAM/128GB) I have had nothing but problems with it. Such as:
The device will not power off or sleep when the ignition is switched off no matter the configuration.
The connected amp constantly remains on.
4G does not work with one of the suggested provider's SIM (T-Mobile). The SIM is recognized, works in other phones, but zero bars in the head unit. Support has zero solution, and the solution in the blog does nothing.
A one pixel wide red line from top to bottom exists in the display. Support will not replace it.
These are just a few of the issues. So I've decided to scrap the board. I'm going to keep the display and the case and put either a Raspberry Pi 4 or a Radxa Rock 3a w/ 8GB of RAM in the case. I'll put a Hi-fi Berry hat or something similar on top for digital audio output and 5.1 signal processing to run to the amp. I could really use some help with the pinout of the UIS7862 40 pin display connector from the community. I can't find this or a schematic for the device anywhere. I'm not certain if this is just using the same protocols as the GPIO standard or if it's something custom.
Looking inside the display case one finds a board with a large 40 pin connector on the back. Its mipi dsi/csi to edp converter is the Lontium LT8911EXB chip, but the board has no part number on it, so again, I can find no schematics/manual for the display board. Both the LCD display connect to this via a 40-pin ribbon and 2-pin wire harness (backlight power?), and the capacitive touchscreen via a 6-pin ribbon. The LCD panel is a Panda116_Wedge V2, but all the pics I've found online have no additional 2-pin power connector coming off the top left, so I'm really not sure what that is. I've attached pics of the display board, LCD info, and the PDF that has some info about the chip.
So I'm not sure if the display connector on the UIS7862 is an unconventional adaptation of a DSI 40-pin output or a GPIO interface, but whatever it is, it carries the display data, touch data, and power for both. If anyone has a schematic showing the pinout, the actual FYT, Joying, or similar manufacturer's manual from this year or the last few years, or any information about this display that would be appreciated!
