any one can upload datasheet or diagram for this phone
thx in advance
What do you mean by "datasheet or diagram"? Exact placement for every part on mainboard or some assembly info? Did you look into service manual http://wiki.xda-developers.com/index.php?pagename=HTC_Vox ?
exactly i need schematic and onboard chip connection
Well, I tried to find that about year ago, but with no luck. Maybe situation has changed and you will be more successful.

Hey everyone, I'm new here , and I thought I'd start with a quick question.
My HTC Universal is a bit handicapped (bought it off a friend who said it was broken, apparently the USB plug terminals weren't fully soldered, but I couldn't connect all of them and it will only charge through USB and nothing else.)
If someone has an HTC schematic or a high-res image of the motherboard, I could possibly try to revive USB transfer capabilities (but that area is a bit damaged from not having a small enough soldering iron ), *OR*, if there is a way to reflash from within the OS using a SD card, that would be great.
Hope someone knows the answer to this, thanks!
Edit: And if it's of any possibility, how much would a replacement board be? Enough to satisfy a 100% working USB connection?
No ideas? If someone can at least give me a schematic or a high-res pictures of both sides of the board then I could possibly fix the USB to 100% functionality.
If you check the WIKI for the Universal you shoul be able to find a link for downloading the Service Manual. It shows the total un-assembly-re-assembly process step by step. You may also find instructions for SD flashing there as well. I have never flashed my Uni by SD, but I have don other phones like that. Most of the HTC's are capable. There is even info in the Service manual telling you what to have on the SD and wht to name the files from proper use. Give it a search.
Thanks! I have the manual already so I'll give it a look over. I wasn't entirely sure and I thought I wouldn't see anything but I'll look more in-depth .
Just a side note, does anyone know where I can get a replacement motherboard and how much it will be? Just curious, as that option might be available if it isn't too expensive.
Hi everyone,
First I would like to apologize if I have posted this topic in the wrong section, but I'm not familiar with forums and stuff like that. If so, I beg of you to just move my topic, don't lock it.
Here's my problem now: I have a Qtek 9100 on which I tried about one year ago to install a non-official WM6 ROM. I first installed a WM5 ROM called "Wizard Love" and then installed the WM6 ROM. Since I didn't like the WM6 ROM on my Qtek, I downgraded it back to the WM5 Wizard Love ROM. But I still wanted to install the official WM5 ROM again.
I tried about ten different ROMs, but each says "ERROR [300] UNCOMPATIBLE DEVICE" and won't flash my device. A member of another forum taught me to install a Custom 1.05 ROM via MUN RUU, but he did not specify that this ROM was for G3 (mine was unfortunately a (perfectly CID Unlocked) G4).
So, after flashing the 1.05 ROM, the Qtek freezed on the welcome screen (with a cup of beer). I tried to flash the original ROM then, using the bootloader mode, but I had the same errors as before. Only the 1.05 Custom ROM could be flashed correctly.
Then, I pulled out the battery and put it in again. And now... my device won't turn on at all! I've been looking for a solution all day long on Google and this forum, and I heard about the JTag. But I couldn't find a tutorial that explains it correctly.
Can anyone help me find one or suggest another solution?
Thanks a lot for your precious help! I need my Qtek back alive!
Have a deep read here:
http://wiki.xda-developers.com/index.php?pagename=HTC_Wizard
You´ll find your way!
Good luck,
Thanks, but I've already specified that I cannot access the bootloader, the phone won't turn on at all, it's completely dead. Neither the screen nor the LEDs turn on. The procedures described in your link are only available for phones that do boot at least in bootloader mode.
the only way is by using JTAG, but you have found one of the threads out there already (as I have seen your post there).
no other way possible.
Yes I know... the only problem is, the link points to a russian tutorial.
Do YOU speak russian?

Enough to understand the manual with help from my friend google translate (if I fail to understand something).
But Russian isn't the biggest hurdle, if you don't know how to read the circuit diagram from the wiggler (which is REALLY simple), nor can you build such a simple constriction, how on earth are you going to connect the JTAG ??
(attached a closeup from a 5 x 3.5 mm piece of PCB where JTAG lines are hand soldered to make my case).
Without the proper tools (I personally prefer to use a rework station and a microscope) and the proper experience you won't come far.
This is why HTC service team will replace the mainboard, they aren't even trained to preform a JTAG. (that is only done by the engineers and in factory), I haven't seen a single HTC service manual which discussed JTAG (and I have seen alot of them).
I guess you're right about the difficulty of this operation.
I've already tried to Google Translate the "manual" (which was a forum discussion. Could you give me the link of yours, because from what I've translated, I think I turned out to be on a bad page).
About the circuit, I understood about everything, except the rectangle on the center and what's inside, and the branch in the upper right corner...
Two last questions: Should I connect the Qtek motherboard to the circuit with melted copper strings (like you did)? and then connect the parallel port to the PC and start using H-Jtag?
Thanks for you reply.

rectangle in the middle is a simple 244 buffer, it's an integrated circuit.
Branch Right top is supply.
This probably is a wiggler JTAG.
Regarding the manual, I grabbed it from the same site (am on a different computer now, without access to the files) .
You should be able to Solder the wires to the mainboard (it's not melted copper).
The picture posted above was soldered by hand with a needle soldering-Iron (but I prefer a rework station).
You need some skill to solder, and the right equipment, using the wrong Iron would ruin the board, as you can see in the Pic, all parts are really tiny (the wires eg. are 0.20 mm in diameter!!)

Hello guys,
Since a couple of days I don't get any fix for satellites. Already tested all known fixes for MTK 65XX devices. Always 0 SNR. I think it's a hardware failure. Could be the antenna/connection to antenna. Do someone have a guide for disassembling the device? Already tried, but there's a cable leading to the black stuff under the battery so I can't pull off the Mainboard part from the display.
Thank you in advance,
Peter
Have an Teclast p10 RK3368 tablet.Dead as it seems to be, caused by flashing wrong firmware..I have my doubts, but maybe it reacts in mask rom mode.
Busy to take it apart to take some pictures, here is the info.
-Teclast p10 RK3368, with 32g nand.
-Nand, Sandisk sdin5c4-32g.
I also tried to find some datasheet for my nand chip, i think its this one..And according layout clk is pin M6...But i am to novice to translate it to what side and the right pin.Or maybe a contact point, hope someone can help me(see page 20). :http://html.alldatasheet.com/html-pd...N5D1-2G-L.html
Also under the nand there are contact points, try to make some pictures from that either.Couldn't find much info about this nand chip.
Thanks!

Uploaded the files, extension etc etc..
Will do it like this.
Underside, the 4 dots are under the emmc, nand chip.

Thanks , if they are not clear enough let me know, maybe it can bring it back alive.
Thanks!
i fond and my tablet back to life

1. download and run:RockChip_Batch_Tool_v1.8
Chose your stock rom. Then
connect usb wire from tablet to pc
with tweezers or any stuff look like that 2-3 second connect 2 point in aria i show you in your pics. your pc noise like rotin driver accept and recognize maskrom mod.
last things hit the restore in software and enjoy and from today, every day 10 time each day say thanks god because you not burn in my country.

A transistor for the RGB LED Front-Panel Buttons ignited yesterday, now I need to know the exact SOT-23 type to get a replacement. You can see the burned transistor in the attachments. My guess is, that it was a SOT-23 A77E, but I'm not sure it this counts for my specific Head Unit. I own this KSH805V: https://www.ebay.de/itm/132576323249
A picture of the location of the transistor is also in the attachments (it's an image from a different radio Model, the location is the same though).
I'd really appreciate if someone could tell me, what transistor their MTCD logic board uses.
Why did it fail? How have you validated nothing else was damaged or has failed?
Did you not identify it from the schematic?

Idk why it failed, my guess is that leaving the front-panel buttons on white (3x LED at max) was too much for the onboard electronic.
I can't validate if something else broke too, I can't see another burned component though
What do you mean with "the schematic"?
