[Q] JTAG for HTC hero - Hero, G2 Touch Q&A, Help & Troubleshooting

Hi guys,
I am gathering some info here about different ways to play witha brocked Hero and it seems that JTAG is the only option for hard bricks.
It seems people from RIFF JTAG have already develloped a special script for this phone, so it is possible to do.
Now my questions... I'm quite new to Jtag. It seems you need the pinout (already found in this site) an adapter and some soft to do the trick. Added to this a new hboot to replace the old, I guess.
Does any one know if there are some home made solutions for the adapter and open soft to do the changes on the hardware?
Any help is welcome!

Another dead wizard

Hi there. I have/had wizard g4, but after upgradin' rom by ruu my phone is bricked. he doesn't even respone to charger.
Now technical details: upgrade was done on i/spl 2.21.001/olip, so after hardspl'ing him. Everythin' went just fine, but in 73% i've realised that i'm uploadin' g3 rom... So i let ruu finish his job and now my pda is completly dead.
I won't be askin' for HELP, i will ask for info. Will anyone can tell me: if i take out 'disk on chip' (cause i think that's the flashrom chip), how i can reflash it? I mean: should i just put nk.nbf from 0x0000 or split rom image onto bootloader, radio and os and put it partially? what are adressess of those thinx and lenght of code? and how can i split nk.nbf?
Congrats !
What your are asking is not easy to do,it requires special flashing tools and connectors,which only the manufacturers and vendors have,It needs new bootloaders,you cannot do it yourself.DOC chip might have to be replaced,it means an almost new phone
Btw,have you tried to force it into bootloaders ? might be lucky,if it gets into bootloaders.well there's no harm in trying,if it does,then you might in luck and safe.
whatdy'a mean sayin' 'force it into bootloader'? if you mean pressing cam button while poweing it on- yes i've tried. i even tried to boot linux on desktop computer, connectin' wizard and typin' 'lsusb' in console, hoping that something like 'xxxx:xxxx unkown vendor' occurs. But, still no luck. even linux thoughts that usb port with connected wiz is free.
I know that only vendors and sevice-guyz know 'tricks' about connecting directly to DOC chip... but i'm still hopeing, cause i've found two unused connector places on mainboard(after disassemblin' of corse)- one in the middle, second next to sim card connector and i'm wondering if there's any chance to ommit BGA-welding(sorry 4 my english).
Have you heard about conspiracy theory ? i begun to belive in it... I think that many people know what 2 do, but noone want to help me from one particular reason: if someone helps me, i wouldn't need to pay in service, so someone will not earn money...
anyway, what do you mean about 'force in2 bl'?

First,let me clear you here, There's no such "Conspiracy theory" being practiced here in this Forum.It's a development Forum and not a Technical Advisory Service of some sort,where experts give advise and earn money.Its a free forum to help the newbies about the problem regarding their phones,We here believe in "Help & Support".The guys and gurus are not trained technical experts,its a voluntary website,where guys help and advise what they have learned and gained to the new guys joining and asking for help and they do it with honesty and to the best of their knowledge without any monetary benefits.
Secondly,Yes ! thats exactly what I meant for 'Force into booltloaders',cuz,may be if it does boot in the bootloaders,then it might be recovered,just a haunch,but if it doesn't,then its another dead paper weight on the desk.
Cheers!
I think it's a misunderstood there. I mean that maybe someone know what to do, but if it would leak to internet then services can lost money, cause what to pay 50$ i.e. if you can repair PDA by yourself?. I mean also that i've searched whole wide web... My polish sites of electronics, pda forums, even those forums where volunteers helps guys who crashed their bioses on PC's. And nothin', no one replies to mails, and if i ask someone directly they say thats no hope for me and my PDA.
I just cannot believe it... Even old PC had protection, if you uploaded wrong code into BIOS and PC cannot boot you always could ISA graphic card and boot from floppy.

focus on the problem:
tell me if u can at least see the bootloader ? If yes then u can have a fair chance of bringing urs back to life
It is because you are not supposed to flash a ROM that is not for your device!
For example, what will happen if you flash a AMIBIOS to a motherboard that uses AWARDBIOS (By your own way for sure)? Flashing G3-only ROMs to G4 device is just like that.
The protection for htc device is not letting you to flash a G3 only RUU in the usual way, you cracked to let it allow any ROM is your own problem, not problem of htc, and htc doesn't have to take care of it.

i've found another way to resurrect my wiza200. JTAG.
But ofcoz noone knows where are testpoints located. But i'll find it. BTW someone can e-mail me fubu of working g4 wizard? lis6502 (at) gmail (dot) com

Do i cracked it? i just found ONE working ruu which allowed me to upload any rom to my device. i've switched nk.nbf files in folder wich ruu was in.
I know also that HTC wouldn't help mi, i'm not counting on warranty or manufacturer help.
No No...
You installed HardSPL to your device, so your device is already cracked (say patched may be better) by you.

uhm, it may be infatile question, but is it illegal? i know thah chaging IMEI is illegal, but is hardspl'ing too?
Cracking SPL is not an offense in law, just violate the warranty terms only.
2 starwonk: man, i'm from poland. i've bought my spv on polish eqiuvalent of e-bay. It's o2 xda mini s, so warranty is only valid in UK. i've told that i'm not counting on warranty. i need and must do it all by myself. and i will do it. Wish me luck

Pinout?

Does anybody have an idea of what the P500 pinout is? And whether it is possible to revive a complitely bricked phone by simply swiching the pins or it will need a box (It's really hard to find boxes for flashing ROMs in Bulgaria).
EDIT: Please only provide answers to my questions, I'm already out of warranty and taking the phone to a service center will cost as much as a completely new phone (Even without replacing thunderg and radios, I'm not sure whether the SIM module is working...)
Wait a little bit. I have some info, but it is somewhere. When I'll find it, all needed info will be in this post
EDIT:

@ashirviskas: Thanks for your efforts. Unfortunately, ROM flash boxes are rare in here, and I don't have any materials and instruments to modify and create integrated circuits. Unless someone else suggests a method without a box,

Unbricking...

Found this thread...
http://forum.xda-developers.com/showthread.php?t=1731255
I am attempting to do this...very hard to accomplish since my motherboard does not look the same as the one in their guide. I already am getting a new phone shipped to me but I figure this could be useful if anyone could learn how to do this. I searched for this particular resistor (r313) and found some other boards talking about this process and it seems like it works. I can't post a picture yet as I am a new member but I have my phone apart and am playing around with it. Does anyone have any idea where this resistor might be located?

[Q] E980 brick with QHSUSB_DLOAD showing.

Ok a few days ago I wasnt paying attention and I installed a ROM on my LG Optimus G and when I restarted, it did not reboot. I have read a number of different forum topics on the subject and done a number of things to attempt to fix it.
From what I read, when the device shows up as QHSUSB_DLOAD in device manager, it is end game.
Ok well I did not immediately give up. I found and installed the Qualcomm drivers. I tried LG FlashTools. Of course to no avail.
This guy on EBAY (item 281151982662) will fix it for $24.99. I think that is a fine deal and since I have exhausted my other options, I was preparing to send it off to him.
AND THEN I found a link to "www(dot)zpsjbbs(dot)com/thread-5097-1-1.html -THIS FORUM POST that implies it may be fixable still with a software solution!!
The challenge is of course, that the post is written in Chinese. Google can translate and I feel I will be able to decipher it and search for and find the various pieces of software and try it out.
Question I have is, is it worth the time? Is it possible? Has anyone tried this method? Anyone have English explanation of it?
Thanks in advance. This is my first post here so I can not post links.
http://webchat.freenode.net/?channels=lg-optimus-g
Try catching Shelnutt2 on this link. This has come up in the past and from memory there is a Qualcomm tool availible, but I am not sure if anyone ever got it to work. There were hex files needed if I remember correctly.
Please , can you tell us what went wrong ?? so no one else tries it if they read it ??
Ive played with the Programs, Its QPST and the hope that it offers up is limited, but Im not a dev either. I can get it to a certain point and that's it, u need hex's off a working phone to get another part of the phone to say ok to get another part of it working... or so it seems, but Im all in on this if anyone wants to dable, this would cure a lot of woes if we hammered this topic. To JTAG my phone it cost 60 bux so the ebay deal if hes credible, is a good deal

[Q] Send in the clones

Hello everybody,
I have been lurking around in the shadows here for a long time and i thought i would pop in and hopefully get to learn some new tricks.
My wife has a S3 mini GT-I8190 with a damaged usb port and i have been given a replacement one by a friend but it is locked to a different network.
I am wondering if i can transfer the OS and files from one phone to the other in much the same way as cloning a hard drive on a PC or laptop prior to upgrading the drives. This i have done many times with windows and linux systems so i wondered if the same procedure exists in the mobile world.
I have rooted the donor S3 and now i really don't know where to go.
Thanks for the great forum and i really hope i can contribute and assist others in the future.
