Hello, does someone have the jtag pinout for the uni?
Or at least the circuit diagram...
I thought the whole point of jtag was that it was a standardised interface connector:
http://www.interfacebus.com/Design_Connector_JTAG_Bus.html
or am I misunderstanding your question?
Cheers,
yes, I know what is jtag but probably my question was misplaced.
what I would know is where are jtag testpoints on universal.
my phone is bricked and the only hope of resurrection is restore the bootloader through jtag
ah right, I'm with you now. have you checked out the universal reference manual? is it mentioned in there?
-edit- no just checked doesnt appear to have any mention or picture of one.
sadly true: the service manual doesn't mention it.
does someone has got schematics for the universal?
sigh! i'm going to believe that my uni will be forever a nice paperweight...
any news?
Hello, I'm still stuck with my uni bricked. Anyone have new suggestions or jtag pinout?
Thanks!
I payed about 50USD to have my bootloader chip replaced here in China.
cant find any other solution for the same brick here. I'v heard someone here fixed his dead bootloader by jtag DOC reflash.good luck.
Hi champro, then does you have got the bootloader chip replaced and not reflashed?
Does you could contact someone to get jtag pinout for the universal?
Thanks a lot.
Any success for bootloader solutions ? I also have a bricked universal.
Thanks
Still nothing...
Hi, I haven't debricked my uni yet. But in the meantime I'm looking for a dead mainboard (or a whole dead phone) in the way I'll could desolder the cpu to trace the jtag pins. When I'll have this pinout I'll count on the support of this forum to find a pal that will dump a working phone to restore mine.

we are allready doing this no need to break two phones
Great!!!!!!!!
Fantastic! May I participate? I'm a average experienced user with jtag interfaces and a dead M5000 to work on!
Please is a lot of time that I'm waiting for the jtag pinout!
ok Lt.Cmdr.Ivan is going to trace the JTAG points from under the CPU of his dead Universal, last I heard he was about to put it in a toaster to get it off
You say you have JTAG experiance? When we find the points could you work out the best/only method etc to fix a broken Universal
Yes, I've already debricked a toshiba e740 pda last year. A complete success!
The best way to desolder a bga is to use a heater gun like those used to remove paint from walls. It is very cheap 15~20$. If you aim to the motherboard with this gun, surface mounted components literally fly away or fall down if is it in vertical position.
I'll wait anxiously for news!!!
i suppose who can afford a digital multimeter, can afford a hot-air soldering station as well. (well under $100 now)
anyway, you can just use a 300W infrared bulb and several hours and the work is done as well.
just pick off the plastic items before applying this heat.
Hi, any news? The number of bricked universal is growing!!!
roglioWhat software you used and what adapter LPT (wigler )or another?
If you know the points jtag as you will write in DOC (DiskOnChip) SPL and IPL ?
Just fyi progress ont he JTAG project can be found here:
The Universal JTAG Project
We found them

Hello everyone! Does someone own a dead universal to sell? I need only the motherboard to desolder it and find jtag ways.
sigh!
Nobody? If you own a dead universal to desolder I could help you to find the ways where are jtag connections!!!
tried ebay?
they go quite cheap
Yes
Yes, but no chance... I'm still looking for a dead uni or a motherboard, but nothing!
*bump* *bump*
Still alone...
pls help me

good luck,
Good morning I have a bricked XDA 02 (HTC Wizard), after a tentative of rom update. Now is dead compleately (doesn't switch on). The only way to solve the problem is the Jtag programming of the processor. I'm looking for the correct JTAG pins, but anyone have traced it till now. I have dismounted the brick and I found a strip on the left side of the board, can anyone tell me what it is used for (picture 2 and 4)??? Can anyone tell me if I can found the JTAG points under the soldering below OMAP processor? Does anyone have the OMAP 850 datasheet? Are the pins close to sim connector useful for what I'm looking for? Thanks to anyone that want to help me...
hi
me and some guys we are working finding that pins for reflashing
join us in thread (dead wizard , never let's revive) to continue it
i attached many important pic in last page , so take a look

Was it really necessary to point to a russian topic?
First of all, sorry if my english is not very good. I'm from spain and I have a Universal that suffered a power failure during gsm flashing and the gsm bootloader was corrupt. It shows the message 'No GSM' during startup and i couldn't find the way to repair... Not possible to reprogram gsm firm, didn't work trying to Unlock, no SuperCID and it seems that neither Jtag (i read that jtag on Universal isn't connected to the gsm chipset).
So... i thought about programming the ROM chip of the GSM module directly accesing it's pins in the PCB. The main problem: this SMD chip has its pins under its body, like a typical PC main processor and not along its borders, so, the only way to see what points on the PCB could give us access to the concerned pins in the ROM, would be unsoldering it... ufff... not an option, but... when I was having a look at the PCB's pictures for the JTAG from the wiki...... Bingo! A completely naked PCB picture! But... oops, the zoom square of the JTAG zone, is just over the conducting paths i want to see!!!
Please! It would be fantastic that the person who made that picture, make another one, where i can see the whole gsm module to track the paths... even better if i could see the opossite side. But doesn't matter if don't!
This ROM employs an electrical protocol very similar to other ROMs and I think It should't be dificult to program using a PIC or similar to drive signals, data and timigs, just to read or write it "as a whole", secuentially. Of course if i find the way I will pos it here with details for everyone.
Thanks in advance! I'm fascinated with your work!
JTAG for radio chipset? I tried to find it but no luck, old problem with hermes/universal. I tried reworking the qualcomm 6250 but nothing. Chip you are talking about is BGA not SMD, and it is very hard to remove it.
Hi All, I just Received A Bricked Vogue As A Gift, Lucky Me LOL Flash Is Completly FF'D Out, Do Anyone Know The Jtag Pinout's And If There Is Any Software Available To Us To Talk To This Flash? I Have My Homeade Jtag Ready To Go But Need Some Schematics, If Not I Could Be A Guinea Pig If Anyone Wants To Shoot Some Idea's Thank's In Advance
*Edit* Looking At The Mainboard From The Back On The Left Side There are 10 Contact's, Only 4 Have A Function With The Exception Of Ground... I'm Betting That's A Good Place To Start
Pin's 1,5,6,8 And 10 Is Ground
TMS TCK TDI TDO Maybe?........... Not In That Order Necessarily.
If anyone has any info that they don't want to make public or spoonfeed instructions i would appreciate a pm rather than no answer at all..... Thanks Again
I realize this may be obvious, but have you tried to get to the bootloader screen? If it's not completely bricked you should be able to bring that up even if the phone won't boot to WM.
Completly Bricked..... Flash Was Formated With Task 2a in mtty then froze before spl was restored
*BUMP*.................................
Ouch
*Update* Vogue Jtag Is Identical To Rhodium_W
1 VCC 2 TRST 3 TDI 4 TDS 5 TCK 6 RTCK 7 TDO 8 NRST 9 Not Used 10 GND
HELP
I just f*^$d up my DZ with wrong engineering hboot
Now it wont boot (nothing works: POWER, POWER+VOL-, except POWER+VOL+ vibretes 3 times and orange led is flashing "Qualcomm CDMA Technologies MSM")
So is there any chance to resurrect my phone?
PLS I dont want to give it to regenersis service, because i waied 2months for touchscreen replacement
sorry but either sending it in for repairs or jtag are the only ways to fix this...
Damn
Riff box with DZ jtag cable costs 150$ (about 500PLN on Polish Allegro)
Its more expensive than new motherboard for DZ
Can I make roff box in home?
Or just soldier some parallel pins from PC to mu DZ mtherboard?
You could get to work with an arduino and a serial port on PC, then solder points to logic board, probably run ya about 50-60$

50-60$?
its still 200PLN, this is better than 150$ (350PLN)
I saw some models like paperduino (http://lab.guilhermemartins.net/2009/05/06/paperduino-prints/)
or AVTduino (http://sklep.avt.pl/p/pl/57409/avtduino+-+starter+kit.html)
Paperduino is about 30-40PLN, but AVTduino cost 90PLN
Still better than 500PLN for riffbox
IMO I thing you'd be better off trying your luck on eBay or some local online bazar or something... get a broken phone for 40-50$ and replace broken parts.
Ex. http://www.ebay.co.uk/itm/FAULTY-HT...78745?pt=UK_Mobile_Phones&hash=item2a314d57b9
Problem solved
