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.
Stu
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.

I want to do everything I can to develop for this phone. What I need from the people here is a stock flash able rom. I have made great progress on this phone but but idk how to build stock roms and at this point I'm not sure I have the mental capacity to learn it.

So...you have made great progress doing what?
There is a Chinese ROM floating around, maybe you can use that.

Without a stock ROM, we have been unable to develop much...
What have you developed, here?
Mostly the community is hacking the stock installed rom, and fixing what Motorola has purposefully broken, but with out a few more pieces and a working sbf, you are not going to get a "Stock" ROM.
If you really want to help out go jump into the bootloader unlock forum:

I use cheesecake 4 times a day every day. If I find something I compare it to what others have found.. What have I developed? Nothing more then a headache. Using the bionic safestrap I have been able to recover from 3 soft bricks. 2 of them using adb to push to the phone and 1 using the restore tool. But i had to remount /emmc to /sd-ext. But I think at this point I am done trying anything with this phone.
One more thing.. what can't we use all the stock files I've pulled from the phone to make a flash able zip?

Seems like you know a lot more than all of us who have been working diligently for the last 60 or so days with this phone.... Why don't you give it a try and see if you can create a flash-able zip.
You can't build a flash-able zip, because you can not zip or tar files on the filesystem that are in use, and the kernel has a ton of files open and locked. the backup software gets around this in a couple ways that we really can't do, and backups are useless to make flash-able zip from. That is why we need the sbf or fxz or source code to make a flash-able, zip or ROM.
That is why we have warned everyone over and over and over, about trying things we post, right now. The information is not to try out, it is sharing of the developers, and for those of us working on actually developing solutions for this phone. There have been so many bricks, because people are not listening.... I am actually thinking of trading my phone with a buddy to get out of this, because I am tired of hearing about all the bricking people are doing, and having to help save someone who did something to their phone that they did after we told them not to.
Unless You Know What You Are Doing Don't Try This At Home. Until we get the fxz or sbf files. I am getting tired of saying this...
P.S. doing work on the cheesecake thing does not make you a Developer. Hell I am not an Android Developer, I am a UNIX and Linux Hardware architect and UNIX and LINUX Kernel Developer, so I am am able to use all that, 20 years of experience on the Android kernel, and I have been hacking and working on phones a long time.
Now I know it is great to try things and learn, but while learning, it is best to try things we say are safe first, then once you are more comfortable with certain things, then try something daring, that you know how to do.
I am in no way trying to insult you, just realize that right now, with the little help we have on the experienced development side of things, it is real painful to get things moving forward when people don't listen, or do things they are not ready for and then keep asking for help when they killed their phone in the process.

The thing is that I am most of the time ignoring these posts, but when you 6 people all did something similar, or like the OP did 4 or five things that messed his phone up, because he/they were impatient, you kind of have to tell them, look if you don't like it, get another phone.

The funny thing is the "OP" didn't do anything he was told not to due.. Instead he/I tried new approaches and have actually been able to recover from a few soft bricks at this point. We get places from trying new things not by talking down to those that try them. I'm trying to help as I own the phone too. I am not in any way "under-educated". I am a .Net developer and I am doing my best in my free time to help the community by opening up this phone to its full potential. Now, Am I impatient.... Hell Yes.. I want CM7 and ICS now. Will I get it now?.. No, but i'm trying to get the rest of you on your way. I cant believe you would try to push someone so willing away..
A better way to go about it would be to post your discoveries and share them to help others out instead of demanding things you need.

We aren't pushing anyone away that is willing to help and we welcome everyone that is willing to hel. But when you experiment know that we might not be able to help you and we have no way back to stock. By experimenting we found root,the bionic's bootstrap and we will have to continue to experiment. Part of progress is by finding out what works and what doesn't.
We need to all work together and not against each other. But with that said if you look at the amount of recent posts with people experiencing problems and calling for help is because they didn't do any research before hand and now they are asking for help for something they could have very well prevented by patiently doing a little homework.
With the progress you have said to have made, start a new thread about it explaining the procedures you went about to recover from the soft bricks so others can benefit from them as well. I can promise you we are all very interested.

Hello everyone,
My Nubia X just arrived and it's in my hands.
Of course it's with Chinese ROM (the dealer warned me before to order it by the way).
Anyway, the aim is to root it, to the phone to die while I'm trying.
Until now, there was no need to root any phone, because I had what I need. But now is a different story.
I know that will be challenge with that phone, but I'm open for it.
I would like to ask you, to give your suggestions what I should try on it, and make it work with Google services.
Consider that my technical knowledge is pretty high.
Thank you in advance!
Bro.
Hey you,
we are in the same situation right now:
So what I currently know.. there is a root solution but it seems like it is pretty weird to understand.
You can find the 'tutorial' here:
bbs.nubia.cn/thread-1396991-1-1.html
Well actually I don't even know if this works but you might give it a try.
As soon as I receive my own one I will definitely try this one out.
It seems like a one-click solution to me (but with all this chinese its kinda hard to understand).
The pictures at least show that they installed Magisk (17.4) which is even one of the newest ones.
Well let me know if it works for you.
Just send me a PM with your Discord Tag (if you own it) so we can stay in touch, if you like.
Cheers
Well, I've try most of the popular ways to install the Google framework, but without luck so far.
In other hand, I put some efforts to make the phone useful and remove the bloatware and install different launcher.
As I'm not tied with the google services that much, it's working for me. (see the screenshot)
hi br_other,
I've installed G-Framework and it works fine.
If the mods finally fix the problem (I cant post anything), I will create a tutorial for you guys.
Until then,
have fun with ur phone :fingers-crossed:
