I have searched, and have not found any information that can help me.
I have a touch that the Service Centre want £90 to repair - new motherboard. Is this fixable with a jtag - If so, does the Holly Gates Schematics for a Jtag Dongle work here?
Has anyone successfully JTAG'd an ELF? If so, was it due to a similar circumstance as myself?
Anything I have come across goes to Russian sites - I'm not russian, nor can I read it.
I have seen posts for other devices, but these seem to all be based on a Samsung Chipset, apposed to our OMAP devices?
Any help would be great, even if it is just to go read a post that I have missed when searching.

Hey, not sure if anyone would care all to much.
I have found a jtag setup I am curently preparing to use, I am going to hopefully be trying to do this tomorrow. I am working on a guide as I do it - as I haven't been able to find one. If this would be useful to anyone let me know, and I will upload it as soon as I have tested it on my broken elfin to make sure it works!
Hey mate, we care and keep us posted with any results.
Good luck!
hey just come into a bit of a stuck point. I have no images to support this.
I am trying to fix the cables to the main board on the jtag points. Aout 5mm wide. I dont really want to solder them on. Does anyone have any suggestions on how best to affix them? I'll try and get some pictures up tomorrow when i can.
Stu
Unable to do pictures today, I will do them tomorrow hopefully on my lunch break, so people can make suggestions.
I am a little scpetical about if this will work. I do not know the history of the device I am tinkering with, but I hope this will fix it.
If anyone has a broken elf they would like to part with for me to test, that would be great (I would pay ofc)

Hey,
Please see attached image.
This points out the JTAG test points, labelled to what they do (in theory) and what pin they connect to the JTAG device from the LPT cable.
I think these are very small to be able to tape them on, I also do not think that they would give a good enough connection. I am going to try to solder the cables on tonight - but in the mean time, if anyone has any suggestions, please feel free to let me know. Any ideas are good!

Hi captainstu72,
I have a completely dead HTC Touch P3450. Really dead. Even when I plug the charger to the device, the orange light (as a sign that the phone is charging now) can not light on.
A service man asked me to replace the machine for USD 80, as he said we can not do j-tag to HTC ELF
Your thread is very exciting. Please keep posting, I'll follow this thread.
Thanks

Hey bombom81,
I'm glad this can be useful for others. I just want to make sure that people don't get their hopes up too soon, thats the thing, I don't know if it is definately able to work, but I know it has been done on other phones with a very similar chipset to ours.
If I have any major break through tonight, I will definately be doing a write up on it tomorrow in my lunch, and If you'd like I can PM you when done so you can give it ago.
Your ELF sounds as though it is in a similar state to mine, so hopefully, if I get this fixed, it may well work on yours!

Yes..I had this problem months ago and I've made a thread for it :
http://forum.xda-developers.com/showthread.php?t=582913
Unfortunately, every suggestions I got from people here didn't work in my device. And I could not even claim a warranty for it as the seller said that the product warranty is already expired too long ago (in the end I knew that the product was his present from his office, and when he said it is new, means that, It is new because He never used it...LOL, not "new" from the factory). So I just keep it in my cupboard.
I think It will be more valuable for others if we discuss here, on your thread, than PM, as I think there are many people are having the same problem like us (as many as I can find after I google "Repair Totally Dead ELF" )
Please, kindly also check this thread : http://forum.xda-developers.com/showthread.php?t=602233
This guy also found a similar thing like yours. I actually don't know a thing about JTAG. In the future, please forgive me if I might ask you some questions about it and I hope you don't mind about my questions.
Thanks for your kind to share your experience with us, I'll keep watching this thread and hopefully you'll be success with your experiment so it can bring the joy for all of us.

Hey,
Likewise, every suggestion I could find had no luck, which I why I decided to dig deeper.
I did come across GallegoT's thread, however, I sent him a PM to see if he had got anything sorted, but I have never heard back - So I created a new one.
I was going to keep this thread posted, don't worry, I was only going to PM you when it was finished - to save you keep checking it
Had a few issues with it last night, tried soldering to the board, but my soldering iron doesn't get hot enough, hasn't got a thin enough tip, and my hands weren't steady enough - Also the wires I was using were fairly wide, I have swapped these for a thinner Kynar wire, and will more then likely be remaking the whole of my setup to make it easier.
Just so you have an idea - I currently have an LPT (male to male) cable which I have taken the end off, and soldered wires to 2 3 4 6 11 and 18-25. 18-25 link then into one wire, as this is to ground the device. 2 3 4 6 and 11 are connected to 100Ω resistors each. These are then connected to wires, which are ready to be connected to the device.
Thats the basics of the device - I do not have an image of what I have planned out avaliable, but you can get the idea of it from what is in this post, and using my image posted earlier.
Maybe you guys have better tools - soldering equipment etc then I do.
When this is done you need to run a program called HJtag, and NoIce. I have an idea on what to do for these, however, I have not tested it yet to want to post it on here.
Like I have said though, I will be making a guide that is as full as I can.
I will try some more tonight, to get the cables connected, and hopefully then will be able to give the whole process a go.
Thanks for your interest in this thread, even if I only manage to help one person, at least then I feel as though I will be giving something back to the community on this site.
(I'll point out now - I did not have a clue about Jtag before now - but I also have some links I will post which make some interesting reading!)
Stu
Hey to anyone who is still watching this.
I have just got my elfin all wired up, ready to go, circuit is fully continuous and there are no bridges (I haven't soldered for more then 8 years!)
However, I have been a bit stupid, my pc doesn't have a parallel port. I'm going to buy one tomorrow and get going - very annoyed about this set back, i'm such an idiot for not checking!
I'll try it tomorrow night hopefully, worst case would be friday/saturday - A long time since starting this projct, but my hopes are high and I really hope I can help some of you guys out there!
Just thought I should update you all, I don't want this thread to become dead... like our elfs
Stu
LOL..no need to worry that your thread is dead.
I'll visit this thread everyday to see how it's going
BTW...do we really need the LPT Socket to do the JTAG? if so, then I will have to ask my IT man in my company to find me a "no-used" LPT socket, lucky I have an old Pentium 3 PC that I might be able to use it for this JTAG matter.
Please update the step-by-step tutorial here with photos so I can follow you easily. FYI, I am blind in this JTAG matter, so please do not mind to answer my next "silly questions".
Keep going! Thanks
Parallel is the only interface I have found to do it on - I would have much prefered usb or something more up to date, but we can't always have what we want.
Below are a few links that I read through before doing anything, just so I could get a vague understanding. I'm workign on the guide today on my lunch - the last part will have to be in theory.
Jtag Introduction
Someone Jtag'd an Ipaq (not the same but the concept)
Has some links to JTAG
Program we will be using for the jtag
NoIceDebugger - A program I will be using
What I think our Processor is
OMAP 850
Again, I will be making a an actual guide, this is just some reading before hand that i did that may be useful!
Stu
hey, well, i have a parallel port and have attempted the jtag.
It didn't work.
My guess is i was using too long cables, or something has come loose. My continuity tester has now died so i will be testing again on the weekend.
I'm going to post the guide i am working and what i did tomorrow. Maybe someone (bom81) would be able to give it a go and do well as i'm sure he will.
Sorry for the failure, but i am really optimistic that it will work, and that it didn't only because of something i may have wired wrong that someone else does right. I'm going to try and get a thirc elf to break and fix as well as it may just be the one i am doing is beyond repair.
Bom81, if you give this a go, good luck. I'm sure you'll have some luck!
If anyone else tries when i have the guide up, please please let this thread know, even if it doesn't work.
Stu
Hi Stu..
Can you give me the russian forum that explain about this jtag on HTC Touch.
I'm going to learn it there.
BTW, how long have you made the cable? have you cut it shorter and try again the connection?
Try to read this thread : http://forum.gsmhosting.com/vbb/f98/htc-elf-dead-after-wrting-elfin-rom-650359/
This guy has the same problem with us but finally (or luckily?), the device could come to Bootloader mode. I'm going to try to PM him, so he can explain how did he get the device work.
Thanks for your try.
Regards,
Bom81
This is for the wizard - same omap 850 http://pda2u.ru/forum/index.php?showtopic=348
I can't find my link for the touch, it may be on my home pc, but it was on the same website iirc.
Cable was about 50cm's - Too long, so I am remaking it to around 15cms tonight, but will be fun as I do not have my continuity tester to make sure that the circuit has the right resistance etc. before I think I was going over by too much due to cable length.
I have started the guide, I just need a few files off my home PC, so I will do this tonight again.
It really annoys me when other threads/sites do not put everything down they have tried, the internet is for information, not for saying, "ha, i've done it!"
I'll try again tonight and tomorrow, I think I have my LPT PCB sockets waiting to be collected, all the way from China, so this will be easier for me to do ultimately.
I haven't yet given up hope, and I'm sure that if I get my document made, someone will be able to tweak it and further help us.
I just don't know how many people are using the Elf's anymore, its fine there being a thread saying we have 900's htc touch's, but how many still use them and are active on this community.... but I digress.
I am really sorry that I am not good in Electronic thing, nor that I know how the electronic equipment works.
But I will try to learn from the website url you provided. Afterall, my HTC is already dead, it will not be a big problem if I make some experiments on it. If I'm lucky enough, I might wake a Frankenstein from his dead. LOL !!
Thanks,
Bom81
JTAG HTC device
Thanks first of all for your effort captainstu72 and bombom81, very interesting thread.
I am also in the same situation - having a bricked device (flashed wrong ROM and/or wrong carrier) and thus also interested in getting a serial cable hooked up to it no bootloader - no reset. The device is therefore software-wise dead.
I would therefore also love to try your procedure to getting a JTAG connection to the device. I have not been dealing with soldering on electronic devices since I did this on commodore 64... quite a few years ago as you imagine but therefore even more exciting.
I will check this thread and get a serial cable. Oh does the H-JTAG Software also run from linux since I only work on linux on this machine?
Thanks in advance and let me know if I can be of any help in this.

Hi Stu and ITCons (welcome to the thread)
I've read the Russian website and have made a translation of the thread from Russian to English using Google Traslate.
Unfortunately, as I said before, I have no competency in electronic, but I'll try to learn.
All credits for the compiled document will go to user id : MEDUSH and ARCC in the Russian Forum (PDA2U.Ru), as they mentioned this document might be reprinted by their copyright.
Please have a read to the document I attached...I'll come back if I'm finding out something (as this week I'll face my busiest week of the month, there are some reports in my daily jobs that I need to prepare to my Boss...LOL).
Thanks for your kind attention.
Regards,
Bom81
Thank you very much Bom81
I have found another thread on this forum as well in the gene section, which shows how they did it on the gene too (omap 850 processor as well) I have posted on there to ask if anyone can relink to the revised download, but so far, there has been no update.
I'm going to go through what you have posted tonight bom, it matches most of what I was going which is always good (from my point of view, as it means i wasn't chasing a lost cause)
Sorry for not posting the guide yet, i'm slacking! But now, obviously, it does not matter so much as bom has posted an excellent guide in his post.
ITcons - I have had a (very) quick look, I don't think HJTAG runs on linux, although I would be interested to see how it would work in cedega/wine (this is not something I can test personally), I hope it would be able to use the LPT ports etc correctly - but again, nothing I really have a whole lot of experience about.
I'll see how it goes tonight, hopefully I should have remade my circuit again, and will be ready to test once more! - This time I am using an LPT PCB Socket - hopefully easier to do as there will be less in the way of resistance from excess cables.
Stu
i haven't been here for a few months due to the job.
I find this place has changed too much and i can't find the useful information at here any more, such as, i can't find how to hard reset or enter the bootloader for a HTC model (HTC diamond,HTC HD7,etc), but those information was very easy to found at the forum/wiki before.
May i know what's happened here and where can i find these infoemation?
Thank you very much for your advise!

it that means we can't find those useful information at xdawiki any more?
I don't know about the xdawiki, but xda is still excellent for finding information. Basically everytime I google anything xda is the first hit. This website singlehandedly helped me unbrick a droid2, which then led me to join this community.
Got to have a bit of faith.
Sent from my DROID2 using XDA App
why all those useful information has been delleted from the wiki?
Idk about infos, actually i've always found what i needed, and i still do...tho there's one thing that changed quite a lot: the "quality" of users...i'm not starting a rant here, i just wanna say that the android explosion made xda more mainstream, and this has ofc pros and cons. The community is probably bigger now, but there's a lot of kids around, maybe because android appeals young people much more than winmo used to do...at least that's what i think. Not saying that young people are annoying in general, most of them know how to behave, but ofc some are just not mature enough and spam around with stupid posts or start useless threads, flash things without knowing what they're actually doing and then start nonsense complaints cluttering dev sections. Just my 2 cents...
Hi there,
A few months back (pre prime) people were quite active on getting nvflash to work for SBKv2 devices. Now lately I barely hear news. I'm quite curious: is this dead? or is work still being done?
I really would love to get ubuntu running as atm I feel android is quite limited as a tablet OS.
Wrong section, I'm afraid...

As curious as I am about this too it is non the less the wrong section post in general or q & a
Sent from my HTC Amaze 4G using xda premium
This thread with it's replies confuses me. Was this initially posted in Android Dev? That would make sense
Nevertheless, the question still remains. I haven't heard anything about SBKv2. I wonder if it's not a lack of effort, but rather just a difficult, difficult task. You would have to ask the guys over at androidroot.mobi really...
I would like also to know were is the sbkv2.
2 questions:
- how was the first sbk key found? from what I understand it is saved in the hardware someplace that it is not readable, so there is no way it can be extracted. maybe the first was leaked from and insider as Asus? or was just the default for the tegra?
- any chance asus will provide an unlock tool for the TF101 with the one they will release for the Transformer Prime?
It was leaked.
I think it might be time to petition Asus for the rights to our device. It worked for the TF201 owners. And honestly, its ridiculous to say we shouldn't be able to know the SBK (and I'm willing to void warranty for that)
Thanks for the replies and yeh it's sadly as I feared. I guess we need to start a petition about it.
And about the mispost, yeh... kinda was in doubt when posting. As well the question IS development related my humble apologies for the mistake
btw seeing I have a dock-drain on my transformer I mailed em.. also with the inquiry about the SBK let's see how they respond
Hi everyone!
I´m also curious about that same thing, and I would be happy to sign a petition =P.
yea, noone knows whats going on?

"unstable." That's an interesting choice of word. I'd say that when I try to dance, I'm pretty unstable. I'm also unstable when trying to balance on a tightwire. Does that count?

Oh! Why didn't you say so? Obviously, most people on these forums are mentally parted! As well, we often part with our mentality.
Am I missing something mental here? Perhaps only part-way?
Well, in any case, I hope you didn't take my comment personally. I certainly didn't mean for it to come across that way. When I saw that image you linked, I giggled and immediately pictured a frustrated XDA member heading to Samsung with ICS-demands on their mind and a hammer in their hand.
Have a nice day, Gary.
Remember about a month ago when XDA came out with a book about rooting and flashing ROMs?
I was just wondering if there were any books (or guides maybe) like that, that showed how to make ROMs from scratch, not through all of these annoying kitchens. (Don't really like them, they make me feel like a noob... of course I suppose I am)
So whatever, that's really about it. Thanks guys!

Pretty awesome, never heard of Lubuntu before now. I'd consider it, but any recent tutorials I've looked at use Ubuntu. (Sadly though, they're ridiculous! For example, there was a post about compiling Jelly Bean from source code, and its practically not even in English! I mean I know some coding and all, but despite that, nothing is explained. It just do this like "do this and then do this and this and then we're done. An don't worry, there won't be a troubleshooting page because we know all you out there are experts.)
Whatever, that's my rant. Hopefully a mod will come along some time soon and point us in the right direction. Fingers crossed. :highfive:

Lubuntu is basically a lighter version of Ubuntu, still runs on the same principles as in version number etc. I understand your frustration with regards to where to find "how to" code, but, my view on tutorials is exactly that where aspects of what you're supposed to be doing are not explained. I think we need to be looking into another category for books, e.g. a coding practice used for android. See what happens
Yeah I suppose you're right. Off to Google/Amazon!
(of course if anyone sees this and would still like to post, by all means, do so!)

It is by far the most in detail book I've seen. Just look at the overview of the chapters! It's just like what I was looking for! Woohoo!
Oh man $50. Hard being a broke student.
I would love to learn to. Anyone can tell me where to start? What languages i need to learn (java, linux, c++, etc)?
Any help will be greatly appreciated.

If your tomato just so happens to be running a version of android that can support the Kindle app, you can actually get it for about $40 too...
And while I'm not an expert in this field (in fact I really don't know too much) I do know that android uses java and converts it to another language using the dalvik machine. So if you really have no where to start, try learning some java.

This is a great guide thanks
Thanks, good guide !
That book looks more related to security than anything else. Anything for development in particular?
If you look at the insides though, it shows how to create the internals, with step by step pieces. Chapter 7 (I think) also has 6 popular methods to obtain root access.
Look at the sneak peek and read the summaries of the chapters. It's definitely going on my Christmas list.
EDIT: As for anything solely for development, I have yet to find anything like that. Hence the reason for posting this thread.
Well, my tomato can support kindle.
Anyway, great thread. Hope someone who can help us reads this and decides to help us further.
