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.
Best Regards,

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
Trials are over and over 10 captivates successfully repaired at this point with over 95% success. Pm me if you need any help with a hard brick...
ill take one too!
for other reasons!
Sounds like my phone!
id like to atempt to make a connector to help you guys out. i have a couple ideas and the tools for precision work but dont feel like disassembling my phone for the proto-type proceedure. if you get a couple phones maybe i can help out.
Danny, the connectors are available online, however if you'd like to help, we could use two circuit board like this:
http://i1098.photobucket.com/albums/g374/adamoutler/solder_board.jpg
If you make these, please let me know. this would allow plug-in access.
Alrighty I have one coming my way. Still looking for 2 more. Come on bricked Cappy owners, this is like a golden ticket here.

well im waiting to here from my friend who was a tool and die maker still. he is out of town. would really like to use his more specialized tools, high spindle speeds are needed for the tiny tooling needed and a jewlers drill press would be better than what i have. i could do something a little makeshift with a dremel but would like to do it a little less sloppy. also curious why it should be 2 pieces? just trying to figure out what you are seeing...
Bump. I'm still looking for 1 to 2 more units before I go official with this skill. Please contact me if you are in need of assistance.
Hmmmmmm... interesting thread. I shall subscribe. Might I request some photos and a little friendly info on your project to be posted in this thread?

YouTube "vibrant jtag" and the first video is of me doing this on a Vibrant/i9000. The project is the same but much harder on Captivate. Although it's no cakewalk on anything with how small jtag points are (.1-.2mm in size)...

Maybe you'll get more to bite with all the mix ups of bootloaders between 2.3.x and 2.2. Seen at least 5 ppl between various forums say "flashed back to 2.2 from 2.3 and bricked "

I would love a JTAG adapter but currently none is available in the whole world for this phone. Member AdamOutler has been slowly fabbing one up for other purposes that may benefit me in the JTAG quest. But there is also a chance my skill will develop first and allow me to directly solder to the pads which I have managed to already do once and I'm hoping for some repeats on the boards I have currently in transit to me! If all goes well, I can go live with this service middle of next week.

PM sent. You qualify as my potential last trial run before real service is offered. Check your inbox and get that bad boy coming my way.
Just wanted to pop in here and say THANK YOU to connexion2005 for his awesome work.
I sent him my hard-bricked Captivate a few days ago, and he was successfully able to recover it with with JTAG. JTAG has been something I have personally looked into when I was more active with the Captivate, and I can say that soldering to the main board is a real pain, and I applaud him for his skills in being able to do so. He was able to fix my phone and return it very quickly. His hard brick recovery service is a real asset to the SGS guys!
Thanks again!
UPDATE: I'm now 2 for my last 2 in successfuly (BLACK SCREEN OF DEATH) hard bricked / corrupt bootloader resurrections.
When a JIG doesn't work, I can still save you!

Hi all,
Yes this is true. I am one of those 2 phones resurrected from death!!!! Really thank you.. I know it is a hard task... so helping accomplish this and of course saving the phone is priceless http://media.xda-developers.com/images/icons/icon7.gif
Really thank you!!!!

If you have a hard bricked captivate that is no longer in warranty and is currently of no use to you, I'd like to practice with the motherboard and attempt to JTAG repair it. I'm practicing my skill at the tiny points on a Captivate board in an attempt to be able to offer JTAG Captivate debricking which is practically offered by only a few places in the world.
This is a REQUEST for any/all Captivate's that are not water damaged, and were hard bricked by a bad ODIN flash, firmware OTA upgrade or bootloader upgrade. If your phone has the black screen of death and won't turn on, this is for you. If it shows ZERO signs of life, this is for you.
MODS: This is not an advertisement for a service but a free offer of helping out both myself and the owner of the phone. There is NO PROFIT made on this. I will even cover your S/H fees to and from my home.
This process currently has a moderate chance (50/50) of damaging the boards points for JTAG owner's, this is only for people that don't currently have a warranty in effect and have nothing to lose versus throwing way a board I may be able to fix. If you have a warranty you are advised to go through Samsung or AT&T for a replacement not through me on this potential trial fix.
If I fix your phone, it's absolutely free for participating in my practice session with Captivate JTAG soldering. I have successfully mastered other Galaxy S variants (Epic, Vibrant and i9000) but the Captivate is by far the hardest phone to solder to.
I'm looking for 3 phones. Don't miss out on a chance to possibly have your paper weight restored at no cost!!!

Hi everyone,
I would like to clear out some points before posting my issue.
1-I have been reading hard brick threads on this device in this forum for 3 days, I am posting my question because I want to get clear answers on what my options are at this point. I have not seen not even 1 solution via Jig, which seems to be the easiest method.
2- The reason I bricked my phone is [most likely] I flashed a kernel that was intended for the N7000 model, although this might not make sense to some of you , for the sake of getting proper help, please hold back on comments that point out how much of a non skilled fan I am and how could I have got caught on such an obvious mistake. Comments like the ones I am describing just wont help so please you might as well keep them to yourselves.
3- Please do not take me as a pedantic person, I just happened to have read enough answers to know that there are highly skilled people who want to help others while some others just love to spend their free time spamming threads. I certainly do not have enough knowledge and skills to perform the jtag method since I cant even solder.
I was trying the JellyBeer rom and I flashed their kernel on TeamWin Recovery, what I do not understand is why did it brick, because I actually realized my mistake soon enough and I performed a restore to my previous rom/kernel, to my understanding, this brick should not have happened in the first place. But when I went ahead and rebooted the phone, it just turned off in the middle of rebooting never to turn on again. Its dead, it wouldnt even charge nor go into download mode or recovery, no vibration no nothing...
Returning the phone to the store is not an option for me as I brought this phone from the states to my country (Dominican Republic ) and is out of warranty.
To me it almost means that I dont have no choice but to keep using my sisters pink motorola that btw is like 10 yrs old until I can wait till some day to have that kind of money again and get a new one. I am leaving the final answer to the experts in this forum.
..If you actually read the whole thing I must thank you, because I know its waaay to long. Counting on you guys.

Hello, a week ago I was trying to restore my phone back to the stock rom, it is a Samsung Galaxy i727, and now is dead or HardBrick, I´m from Dominican Republic, searching in the internet I found a local Mobile Repair Center offering the Jtag service in just 24 hour my phone is back, their name is ALUMUN, if you are in Dominican Republic they are the best, you can find them in google as ALUMUN
I agree with you, we need help not lip service. I too bricked my phone, the site I got my roms added the galaxy 2 rom to the site not thinking it would be a bad thing to add it since they added it to the group of roms I could download for my phone, well that was the wrong thing to do!! I don't live in the Dominican Republic so I need to fix this myself.....HELP PLEASE!! Thanks guys

THIS GUIDE IS FOR ANYONE WITH A GALAXY SERIES PHONE WHO BELIEVES THEIR DEVICE IS "BRICKED," IN A NON-WORKING STATE, IN A BOOTLOOP (CAN'T GET PAST SPLASH SCREEN,) OR WITH A STUCK POWER BUTTON
In no way am I a connoisseur of these android devices, but look around on the forum, I couldn't find any guide for anyone with a bricked phone, or at least for my device, so I'm all you've got.
I'll list the steps that I took in order. My device wasn't bricked after all, it was just the power button, and I'll cover that later.
STEP 1: Stay calm. I was pissed when I thought my device was bricked, but you need to be careful, they aren't literal bricks and they can't take too much of a beating. I emphasize on too much because these devices are quite durable, but don't throw yours through the living room wall because it wont turn on for you. If your device is easily repairable and you break it in a rage fit, whose fault is it then? Keep calm and continue with this guide.
STEP 2: MAKE SURE YOUR POWER BUTTON ISN'T STUCK! DO NOT continue past STEP 2 until you've tried everything to make sure its not the power button. IF, and ONLY IF, you've spent about 30 minutes wiggling that little bastard and cleaning it thoroughly can you continue to the next step. If you haven't tried anything yet, then I'll begin. You're gonna start by taking your device, facing the side with the power button downwards, and gently, but not very gently, tapping it on a table, your hand, something to get your power button unstuck. Tap it on something for about 30 second intervals, trying to turn your phone on in between intervals. If you've done this about 10 - 15 times, then let's move on. We're gonna try what fixed my phone. If there's a possibility that it's still the power button being stuck that's keeping your device from booting, it's gonna be the next thing I talk about. Something is in your button. A sticky substance, I should say. You've gotta clean it out thoroughly, and I have two ways that will work.
Method 1: Go purchase yourself a can of keyboard dust-off spray. Stuff comes in handy for a lot of electronic applications, and it fixed my device, so I'm grateful. Anyway, you're gonna take your can of dust-off spray, and spray it towards the power button on your device, trying your best to get most of the spray in the gaps around the button. Do that for 30 second intervals, powering on in between, etc etc. If that hasn't worked, there's two things you can do. Continue with this method further, or move on to method 2. Continuing with Method 1 requires a knowledge of electronics. You're gonna have to open up your device, by removing all the screws showing under the battery cover. IF YOU'VE NEVER OPENED YOUR DEVICE BEFORE, LOOK UP A GUIDE ON YOUTUBE. I can't really show you a visual, so look for a youtube video on how to disassemble your device. Once you have pried open your device, check out the little white button where the power button lays over. Is there anything sticky on or around it? If so, CAREFULLY scrape it off with a needle or a razor blade CAREFULLY. If there isn't anything sticky on it, spray some more of your dust-off into the small white button. Don't worry if it looks like the spray is turning into liquid on contact with your device, the liquid will vaporize almost instantly. After you've sprayed a decent amount into the button's area, take your battery, and hold it in the position it would be in your device, parallel with the rest of your phone, and touching the contacts. Once you're holding the battery securely to the contacts with one hand, take a pen or your fingernail and press the small white button with the other hand. Does it turn on, and if so, does it get past the boot loop? If you've gotten past the boot loop like I did at this step, then congratulations, you've saved a bunch of money on phone insurance! If your device isn't turning on at this step, and it was turning on beforehand, your battery isn't all the way touching the contacts, or you've disconnected a flex cable. Check for both of those things. If its not either, then you've probably broken your device when you opened it, which isn't my fault. If you're still at a boot loop, try some more spraying and repeat the steps. If you've done this a couple times, and it's still boot looping, continue to method 2, or go on to step 3.
Method 2: Open your device how I explained in the last method. Get rubbing alcohol, and a Q-tip or a toothpick. Dip your applicator into the alcohol, and apply generously to the white button where the power button overlays and surrounding areas. Let it air-dry, or blow it all out, then take your battery, and hold it in the position it would be in your device, parallel with the rest of your phone, and touching the contacts. Once you're holding the battery securely to the contacts with one hand, take a pen or your fingernail and press the small white button with the other hand. Does it turn on, and if so, does it get past the boot loop? If it doesn't turn on after this method, and it was turning on prior, check to see if the battery is all the way in, and check if you disconnected any flex cables when you opened your device. If its not those two things, you've probably broken your device when you opened it, good job. If you got past the boot loop. congratz, you never had a bricked device. I made the same misinterpretation. If it's still boot looping, try this method 2 or 3 more times before continuing.
IF NEITHER OF THE TWO METHODS FOR STUCK POWER BUTTON WORKED, YOUR DEVICE IS PROBABLY BRICKED. MOVE ON TO STEP 3.
STEP 3: Step 3 is just about where I bid you ado. You have a bricked device, and I'm quite sorry for your loss. You have a couple of options at this point.
OPTION A: SEE IF YOU CAN GET YOUR DEVICE IN DOWNLOAD MODE. If you can't get it in download mode, then I'm sorry. If you got it in download mode, YOU MIGHT BE SAVED. I couldn't keep mine in download mode for more than 2 seconds. Once she's in download mode, start up Odin, and boot your stock ROM. NOT CYANOGEN, NOT A CUSTOM ROM, get your stock ROM on the phone ASAP. If you can't get this option to work, move on to the next options.
OPTION B: Take your phone to [insert service provider here] and check if she's under warranty. You better hope, since the other options aren't very bright/cheap. If she's not under warranty, or they're gonna charge you over 100 dollars to replace her, then try some other options.
OPTION C: Get the USB dongle. It'll be your lord and savior if it keeps your device in download mode. Purchase one of these either way, they're dirt cheap and useful as hell. Once she's in download mode through the dongle, connect to your PC, start up Odin, and BOOT YOUR STOCK ROM. NO CUSTOM ROMS. Google your device's stock ROM, download and install it. If the dongle did you no good, then go to option D.
OPTION D: JTAG device wipe. That doesn't even sound healthy, does it? Think of it as open heart surgery for your device, but its a lot safer. Go to bricked my phone . com (I can't post links) they will unbrick your device for a short fee, and it'll be good as new. These are just about your only options. I went to multiple phone repair stores and they denied me service based on the fact they thought my phone was bricked, and mine wasn't even bricked. Get it JTAG unbricked, and you're good to go.
If this guide helped you in any way, there's no need to thank me. Thank a good sum of the community for attracting me to this site, as well as not putting up a guide for unbricking SGH-i727, motivating me to do one. If your device was broken due to my guide, not my fault. You're either a noob at electronics, or you opened your device with a hammer and nails. Thank you xda community for everything you've helped me with device-wise, I'm returning the favor.
Or see vincom's stickies in the development forum.

good post but if you did search you could of found your answer, below is from from the q&a sticky
30) Q. my phone only vibrates, is it hard bricked
A. no, if it has any signs of life its not hardbricked, if you can get it into download mode and install stock firmware, howto HERE , if you cant it might be a sticky power button, read Q#32 and #33
31) Q. will a usb jig unbrick my skyrocket
A. no, only jtag repair will fix a hardbricked phone that has no signs of life, look HERE in the info section for a company
no signs of life(nsol)=hardbricked
32) Q. why does my phone bootloop every few seconds
A. could be a "sticky power button", read the next question and the info section in the 1STOP STICKY
33) Q. how do i test for a stuck "sticky" power button
A. test: remove then reinsert the battery and if the phone turns on by itself and then takes approx 10 sec's to turn off and vibrate then its for sure a power button problem, its stuck, goto the link in the previous answer for a possible fix

Did you confuse yourself? Was it bricked or unbricked?

I think it was an unbricked brick with a little bit of bricking on top.

first off, everyone was a noob at one point. thats undeniable. and second, im not here to defend noobs. im here to defend every person who comes on here having not the slightest idea what to do with their could-be-bricked device, and they end up getting ripped on for not knowing what to do, or for asking a stupid question. do you honestly think everyone who buys an android knows everything about it down to its core? it literally makes me laugh, the incompetence of some people on here. im not even looking for arguements though, just trying to prove a point, and id like to make that clear to everybody on here.

The issue being you said the info isn't out there we say otherwise. The guide is not the issue the issue is the level of disregard for the rules in the first place rule number 1 which is search. Had you followed you would have seen you are far from the first to brick nor are you the first to receive answers on the subject. I applaud the effort but again had you followed the rules from the start it never would have been necessary.
Edit: please remove any and all profanities from your posts or I will be forced to report as it is in violation of xda rules.
Edit2: this guide really only covers power button issues so your title is misleading. Also the dongle aka jig does not work for fixing anything on the skyrocket if it puts it in DL mode that means you could do it normally anyway without it. Also if you have access to DL mode its unlikely you will not have access to your recovery partition as such you could just flash a new ROM. Really about 90% of the info is power button stuff the other 10% is either incomplete or incorrect.

First, that comment you quoted want't directed at you. Second, I can appreciate your wanting to help but this info has been covered a lot. And, no offense, but that so called guide basically says:
Clean your power button. If that doesn't work I can't help you any further.
As far as everyone being a noob at some point you're right. It's how I came here for the first time a little over two years ago. I soft bricked my SGS 4G. I looked around the forums and found all the info I needed to fix it. I never posted a single question asking for help. Then I realized all the other things I could do and started to get involved. I still don't ask for help much. WHY? Because the answers are all already here.

agreed if the answer was hard to find but........the answer was in the sticky above your post
So I've taken A-Teams work and elaborated on it because after 3 tries I've succeeded in rooting 2 of these Assurance Wireless devices.
And you will want to because they do spy on u for 1, and 2, the ADS are annoying. Plus its cool to Learn
thanks. i’ll give this one a try and let you know how it goes

well, i finally got the time to try this out, and about half way through pushing the new setup into the phone, the power switch on my strip got something dropped on it and killed power to the computer. now the computer won’t even recognize the phone.
im gonna mark this down as a failed endeavor, but through no fault of the process. it seemed like it was going to work. i just f***ed it up.
next time, i think i’ll clear off the desk first, and maybe have three or four less beers before i start.
i’ve got a replacement phone coming in the mail (or fed-ex or something). i’ll try it again when it gets here, if they send me the same phone.
Thanks, ShawnWiosna. Your guide also helped
