jtag pinout

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:

[Q] My Desire completely dead!!!

Hi everybody,
Six months ago ive purchased in store htc desire.
I rooted the phone and everything was fine.
Five months later i decided to renew my rom and did again, but something was going worng and my device completely dead. No charging no recovery nothing.
I have a warranty for one year and i gave my device to this store where i've bought it.
One month their technic gyus in lab tried to revive him but unsuccessfully.
In the store iwas told that they connected with j-tag and didn't success.
There is a voltage or something like that in motherboard,but no bootloader. There is something problematic to software,but no hardware, therefore it's not under a warranty.The guy from the store said to me that he tried with j-tag and other methods,but no signals of life.
For replacing motherboard they want 350 dollars.Of course it will solve my problem, but 350 dollars
How can i revive my phone? and j-tag really must to help in this way if only boot is not ok and motherboard is good? So why they didn't success in this case?

You can find here people you can contact that have jtag boxes: http://www.jtagbox.com/riff-jtag-bo...-bricked-phone-riff-box-owners-list/#comments.
If the tech guys told you that jtag didn't help, I doubt that anybody here can do something for you. Maybe the freezer mthod might work for you, but it is an extremely long shot.

Thank you for your reply
1.Tell me if i can trust to these people in contact list that you gave?
2.Can you write what is the freezer method and what's the difference between j-tag and this method?
Thanks

1) Dunno. Those are people who are listed with desire jtag equipment. You said that in the service they've tried repairing your phone with jtag, which I think is the lowest level repair. There is no software solution to your problem. In your situation you have the definition of a bricked phone.
2) Put your phone in the freezer, wrapped in a plastic bag for 5 minutes. It's supposed to to make the circuit board contract and thus braking any short circuits you might have on your motherboard or reset some chip.
Truth be told it's an extremely long shot, I'm only speculating.

[Q] Phone Hard Bricked, Need JTAG Points

Hey Guys & Gals,
Long time lurker, first time poster.
I have hard bricked my Epic 4G. I was flashing the SPH-D700-EC05-8gb-REL.tar via Odin v 1.61. The flashing process froze on "datafs" portion of the flashing process.
The phone's screen went black after awhile, so I decided to pull the stock USB cable from the phone like a smart person. I then pulled the battery and put it back in the phone. When I tried to re-enter download mode I was unsuccessful.
The phone is now unresponsive. No red light when "charging" the phone. The phone will not go into download by holding the "1" on the keyboard while pressing the power button. No response from the phone at all. I have tried different batteries and USB cables with no avail.
I tried removing the battery, pressing the power button to discharge capacitors, etc then placing the USB cable in and trying to enter download mode and every incarnation of that process.
I even tried MysteryEmotions "Reset Button" trick.....which by the way, there is no button underneath the plastic as I even dismantled my phone to check.
I am looking for help in JTAGing my phone. I have experience with doing so on other devices.
First, is it possible to build you're own JTAG to low level flash the mainboard. I do not want to buy a RIFF Box. I have a JTAG I made that is a 20 Pin Serial to 5 pin JTAG with resistors soldered on for another project in the past.
Second, if I can use a homemade JTAG, is there software that can help or can I use the ressurector software from Riff Box?
Third, It looks like the JTAG pins are under the Camera Flex Ribbon, is this correct? Does anyone know the pinout for JTAg purposes?
I don't have the TEP insurance through Sprint. The phone was purchased 8 months ago but I do not have the receipt anymore.
I have considered going back to Sprint and getting a new one for $35 or sending it to Samsung to JTAG it.
How much does Samsung charge for JTAg...it sounded like $35 under the 1 yr warranty.
I have searched these forums extensively with no clear cut answers. Any help with these questions are greatly appreciated.
Thanks Again,
Green Andy

Pull out SD card and battery, put battery back but leave SD card out, boot into download mode (1 key + power button).

I appreciate your response ghostrid3r. Unfortunately, I had tried this tactic as well to no avail.
I am a man that never posts because I believe the answer is already out there and just need to google the [email protected] out of it until you find it, but this problem has me stumped. I tried your method for giggles again but it did not work. Thank you though it is appreciated.

I assume you tried to leave the battery out for about 10-30mins, then retried to get into download mode?

Yes I did sir. I even left it out over night, pressed all the buttons to discharge any remaining power in the capcitors and used my wife's fully charged battery etc without success. Thanks again for the input however.

Sounds like time for a trip to the Sprint store. It is still under warranty so they will replace it.

I'm starting to think that myself. Now since I do not have the "Equipment Protection" insurance plan but am still under manufacturer warranty, a sprint store would handle giving me a new phone and the would send my old phone back to Samsung? I thought I would have to send the phone back to Samsung. Is my thinking correct on this?

Most stores will order you a replacement. Tell them it was on the charger and when you took it off it would not come on.

Ok folks problem solved.
Went to the Sprint store and they were unabe to repair it. Since I do not have the TEP insurance, they charge $35 for a refurbished phone. I asked the sales rep what would I had done if my phone was out of the 1 yr manufacturer's warranty. He stated they would have replaced my phone with a refurb anyway for the $35.
So it's $35 for exchange. I did not have to send it back to Samsung on my own.
I also considered sending my phone to mobiletechvideos.com for $50. I learned about this business from the forums here....I would imagine this business is legit.
A riff box costs $150, which is a JTAG box for cell phones.
Moral of the story, is ODIN freezes.....DO NOT PULL YOUR USB CORD OUT OF THE PHONE! First see if it will eventually complete. If it does not, check the forums to see what to do but do not disconnect the USB cord.
Thanks again to ghostrid3r & kennyglass123 for your advice and help.

Hey there glad to see you found me before making your final decision. I definitely can JTAG the Epic back to life and repair it and would have loved to but hey glad you are back to going. To answer a few of your questions, nobody has developed a DIY JTAG solution, you can't use anything but a Riff Box with the Riff Software and the pinouts are available with the Riff software. Still though, the pins are around .2mm in size and require some decent skill to connect to but you may be familar with that size factor.

Thanks for the info regarding DIY JTAG's connexion2005. I've done the .2 mm size soldering contacts before with a very fine tipped 15 watt soldering iron, a steady hand and patience. It's a fun hobby and a good skill to learn especially since most components are surface mounted these days. You are in my Rolodex for future reference and services though.....thanks again.

For future reference re download all of your odin files pit, tar & rom. Also make sure your usb cable is good. Those are the only 2 things that make odin freeze. Odin itself usually doesn't freeze.

This seems to hold very true. I followed your advice and reflashed my wife's GB leak back to Stock EC05 and Odin behaved itself. The stock USB cables suck. Thanks Again!

Dead Phone RIP ?

Hi ,
My SGH-i927 was working quite happily sat on charge connected to a USB cable on my PC, I left work with the phone in my pocket and when I came to use it a couple of hours later it was completely unresponsive.
It will not respond to power button at all
It shows no activity when on charge either via wall wart or USB, it does not show up as connected to the PC when USB cable plugged in.
I've tried removing the battery for a couple of minutes and also a different battery with long and short presses of the Power Button whiles't holding volume with various combinations there of.
This is not as a result of my flashing anything it just stopped, the threads I've seen using search all seem to be able to get to a boot screen of some description mine is completely dead.
Phone was Unlocked / rooted / backed up + efs backup / running 4.0.4 UCLJ3 Lite Kernel
Anyone have a suggestion on how I might be able to resurrect it or should I put it in a long ship and set fire to it ?

Please note I imported this Phone into the UK
I approached a local SAMSUNG service center and they won't touch it as it's from outside the EU. - Further more on discussing the nature of the problem I was informed it's probably a hardware fault due to IC or Fuse or combination of them. As these are surface mounted components they wouldn't be repairable by normal means and they wouldn't even give me a number for an independent phone repair.
Can anyone know of and can give me the contact details of a repair person based in the UK who'd be willing to look at it ?

Thankyou,
I appreciate the time taken to respond and especially the offer, however although not completely inept with a soldering iron changing the motherboard may well be beyond my expertise, but I'd be willing to give it a go if all else fails.
I have managed to locate another repair center reportedly having Samsung Qualified technicians. Initial communications seemed to suggest they could deal with the assessment which they provide for free. I have sent the handset to them and am now awaiting their report.
If things do not work out with the repair center, I would like to contact you to discuss your offer further.
Regards

Response from repair center - beyond economical repair - but no further detail.
I think I'll call it quits now and just invest in a new handset.

http://www.newegg.com/Product/Product.aspx?Item=9SIA2KF0YV4051 $145 brand new.
I might be willing to part with my own for a reasonable price too, but it wouldn't be less than $100. Has an extended battery. Probably better to get a brand new one.

Desire Z wont boot!!!

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$
Sent from my Nexus 4 using Tapatalk 2

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
