JTAG, JTAG, what do I need to rip this baby apart? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
been digging in the "fun" world of buying a JTAG. Jeeez.... Loads and NOT cheap....
What do you guys and gals use?
I looked at so many different ones and I don't know really what to buy here to get some more insight in the hardware.
Saw there are USB-Jtags but does that work with the phones?
Google came with Segger? They had an "edu" price that was in the range of accessible.
Saw this one as well: "Riffbox - Best in the Galaxy!". Sounds...uhm... yeah right.
Or is it really good and they just have the worlds worst marketing director?
The Segger seemed more general purpose?
Saw there are some variants that doesn't need welding but I guess you must. Schematics?
Of course it would be great if it worked for a Raspberry as well so I could automate my house like the master of the world!
And I need one again. I think I found my golden road in life, but I don't want to throw away 1k Euro on something worthless but listen to you who
have experience.
Because I really want is to have a way to plug something into the phone and read out the secrets it possesses
I mean, E-Fuse data, doesn't that just sound like you HAVE to get?
Please. Can you give me some advice here? :fingers-crossed:

is it possible to port the real iPhone OS into Hermes?

They said that the iPhone uses a similar CPU that is on the Hermes and other pocket PCs.
http://www.engadget.com/2007/07/01/iphone-processor-found-620mhz-arm/
If it this is possible it would be the best port ever!
A clever person could certainly find a way to create a ROM dump of the iPhone.
But you'd almost certainly brick your PocketPC by trying to flash it to an iPhone ROM.
not possible. hardware is different altogether.
someone please tell me this topic isnt really here....
this topic really isn't here
Apple toyphone vs Hermes
Apple's phone is a toy, not a work machine. It's more a media gadget, good for tunes, videos and stuff. Not for business functionality.
Dumping that ROM into the Hermes would be like putting a Smart Car engine into a Cadillac (Ok, I am exagerating a bit)
The closest thing to an IPhone will be to get Touch to work fully on the Hermes, and we are close to that if you read the threads here. Then it will make the IPhone the obsolete object that it pretty much already is.

how true.... its incredibly hard not to lock this thread.. but i would hate to censor this..
...... somebody hand me a gun, and the address of whoever would commit such a henious act. Now WM is FAAAAAAAAAAAAR from perfect....... but it's a hell of a lot closer to getting there then whatever the iphone has. If this was a brain transplant we were talking about your basically asking "Can I put the brain of a worm inside this human?"
You guys had to know this question was coming. Calm down, this too shall pass.

Sounds like what I told my wife concerning her kidney stone... when I picked myself off the floor I realized some questions shouldn't be asked, ehehe!
Is it possible to port Carmen Elektras body onto my wife?
Well, kidney stones don't ALWAYS pass. I should know, I had an 11mm one that got stuck in between my kidney and my bladder that I had to have surgery for.
Luckily, the iPhone isn't quite as bad as a kidney stone. Being impaled might be close.
I think if nothing else iPhone is good to get M$ to wake up and start making WM more userfriendly. Looking at the iPhone "tutorial" video it is for sure that things are really well thought throgh in their GUI. VERY userfriendly.
I wonder if M$ didn't help HTC making the TouchFLO happen really quickly...
yes the iphone uses an ARM processor but the hardware is completly different... not to mention the OS is using 700MB of the FLASH space on the ishite anyway....
this is avery good topic. Just joking...!!!!
Hi,
There is already an iPhone Os Image downloaded from Apple. The file is around 90 MB. it is encrypted in some parts, but the meaningfully part of this issue is that iPhone is a completely different hardware with a faster processor with tailored features. It means you can´t.
But if the hardware may be similar, the OS X on iPhone has a 2 strong security systems for slow down the crack from enthusiasts. Up to day, after 3 days, the crypted portion of the iPhone have not been decrypted.
It´s mean too... if you like it, buy an iPhone BTW, there is a buzz about exchange support on iPhone. Just a rumor...

Taguapire.

its a restore IMAGE not the whole OS...
I am going to correct a few people here.
First of all - it IS possible to get the iPhone OS to run on a hermes or similar. It would take a hell of a lot of work though, and it would have to run in a virtual machine, and it would be slow and worthless. But I don't think it's nearly impossible. I do think it's highly unlikely that anyone would do it.
And once again, I gotta call out the iPhone hatah's. A toy, huh? Just a toy with many features more advanced than any other piece of technology on the market. Not ditching my 8525 yet, but phones are going to get better and Apple is going to be responsible.
Apple responsibility.
. . . yes very very responsible.

1st post

Hi I actually have nothing constructive to offer just wanted to be the first to post on this forum.
very constructive indeed... and, you weren't the first... OliNex were
Very constructive!
Are there actualy any specific HTC accessories anymore? Now that they insist on putting that damn mini USB port on everything.... Stuff like wired and bluetooth headsets should work across the board...
The only accessory I can think of that changes with each model are the powered in-car mounts. I spent a few quid on one for my Wizard and then bought the Kaiser a few months later and it's a different shape and there's nowhere for the audio jack to go! D'oh!
Lesson for the future: Buy a cheap adjustable mount and just bung a charger cable in the phone!
well spare battery never hurts!
im particularly interested in the video out. saves me carrying my notebook to conferences when i have to address a bunch of people on the future trends of microelectronics and microphotonics.
hope the resolution is good.

i have video out on my imate 8502. quality isnt great.
However what I would like to try is some video specs. now that would be great to watch movies with. anyone know of good ones?
I've always had the best luck with stuff from Seidio. I'm done wasting $ on the Ebay crap.
**EDIT**
Eagerly waiting for this phone...

What is your one piece of advice?

Everyone knows something the other does not. Be it a new user or an experienced user. Such as using Chainfire 3d removes lag in some games or using specific settings is better than others like 600 mhz is better than 748 mhz in a specific rom or maybe a app like Titanium Backup can be used to freeze apps.
The list is endless!!! What is your one piece of advice that will get us X8 users the best out of the phone! Maybe it is an app from the all section or the app section here at XDA if so then just post if here.
Or just simply advice how to use search. lool
Hope it all goes well.
Hey have large amount of free ram will increase the performance.....
USE SWAPPER.......it is a effective method to performance....
remember to full wipe when installing custom roms (depends)

Use swap and CF3D for better gaming performance

Never stick to a single ROM...Every ROM has advantages and disadvantages..
My rule:-
search the whole ROM/patch/anything you apply
and see what it mods,where,why,etc,etc
This is the only way to give away the n00bness !!!
Always do a stock rom backup before going into a new rom,saves u the trouble alot.
http://youtu.be/I5NAPZp2w-o
this is my advice
If I could offer you only one tip for the future, sunscreen would be
it. The long term benefits of sunscreen have been proved by
scientists whereas the rest of my advice has no basis more reliable
than my own meandering
experience…I will dispense this advice now.
Enjoy the power and beauty of your youth; oh nevermind; you will not
understand the power and beauty of your youth until they have faded.
But trust me, in 20 years you’ll look back at photos of yourself and
recall in a way you can’t grasp now how much possibility lay before
you and how fabulous you really looked….You’re not as fat as you
imagine.
Don’t worry about the future; or worry, but know that worrying is as
effective as trying to solve an algebra equation by chewing
bubblegum. The real troubles in your life are apt to be things that
never crossed your worried mind; the kind that blindside you at 4pm
on some idle Tuesday.
Do one thing everyday that scares you
Sing
Don’t be reckless with other people’s hearts, don’t put up with
people who are reckless with yours.
Floss
Don’t waste your time on jealousy; sometimes you’re ahead, sometimes
you’re behind…the race is long, and in the end, it’s only with
yourself.
Remember the compliments you receive, forget the insults; if you
succeed in doing this, tell me how.
Keep your old love letters, throw away your old bank statements.
Stretch
Don’t feel guilty if you don’t know what you want to do with your
life…the most interesting people I know didn’t know at 22 what they
wanted to do with their lives, some of the most interesting 40 year
olds I know still don’t.
Get plenty of calcium.
Be kind to your knees, you’ll miss them when they’re gone.
Maybe you’ll marry, maybe you won’t, maybe you’ll have children,maybe
you won’t, maybe you’ll divorce at 40, maybe you’ll dance the funky
chicken on your 75th wedding anniversary…what ever you do, don’t
congratulate yourself too much or berate yourself either – your
choices are half chance, so are everybody else’s. Enjoy your body,
use it every way you can…don’t be afraid of it, or what other people
think of it, it’s the greatest instrument you’ll ever
own..
Dance…even if you have nowhere to do it but in your own living room.
Read the directions, even if you don’t follow them.
Do NOT read beauty magazines, they will only make you feel ugly.
Get to know your parents, you never know when they’ll be gone for
good.
Be nice to your siblings; they are the best link to your past and the
people most likely to stick with you in the future.
Understand that friends come and go,but for the precious few you
should hold on. Work hard to bridge the gaps in geography and
lifestyle because the older you get, the more you need the people you
knew when you were young.
Live in New York City once, but leave before it makes you hard; live
in Northern California once, but leave before it makes you soft.
Travel.
Accept certain inalienable truths, prices will rise, politicians will
philander, you too will get old, and when you do you’ll fantasize
that when you were young prices were reasonable, politicians were
noble and children respected their elders.
Respect your elders.
Don’t expect anyone else to support you. Maybe you have a trust fund,
maybe you have a wealthy spouse; but you never know when either one
might run out.
Don’t mess too much with your hair, or by the time you're 40, it will
look 85.
Be careful whose advice you buy, but, be patient with those who
supply it. Advice is a form of nostalgia, dispensing it is a way of
fishing the past from the disposal, wiping it off, painting over the
ugly parts and recycling it for more than
it’s worth.
But trust me on the sunscreen…
Dont think sticking the phone in the washing machine will clean the insides of the phone

Search be4 posting!!! Biggest problem... people post and then say they dint find anything relevant on searching!! R we gods? If no, then howcum we found it!
Sent from my W8 using XDA...
the best thing to do about battery drain is
- let the phone cool off for about 10 minutes after recharge
- use usb for recharge
- use undervolt
- dont overclock too high, 748 is already enough
- MINICM7, best of all for unlock bootloader with the best gaming performance
correct me if im wrong
My advice. Do not use swap unless you have to. It can and will spoil your SD card faster.
uhhm..... read the whole OP, before doing something stupid(BRICK) TO your phone!!!!" Chill !!!!!!
*yawn*

evice suggestions for demonstration of JTAG benefits

I tried to get some help in the Q&A section, but it appears this is more technical/hardware seeking question than just generic "which phone" thread.
I have been suggested Samsung Galaxy Spica/i5700 by boofman (thank you), but the device is cost prohibitive.
I would very much appreciate anyone's suggestion.
I am planning a presentation to demonstrate the benefits of JTAG for data recovery on embedded systems. The audience has approx. 12th grade education, but higher than average computer understanding.
I have most of the equipment already, including a uLINK2, Bus Blaster, and Raspberry Pi for the UART-to-USB, and OpenOCD for the software.
What I am missing is the simplest cell phone (or other inexpensive embedded device) to make the demonstration.
I would like to connect to the device and list the devices on the JTAG chain, and recover the data from them.
What cell phone brand and model would work well for this presentation?
I would need to know the JTAG points, have access to the data sheets of the onboard chips, and since it is out of my own pocket, I hope to get the phones on eBay for a low price.
Any suggestions are welcome.

Check out gsm-forum, under the hardware repair section.
Googling for jtag pins and your phone model number usually works for me. I'd assume you might have to wait a little bit for brand new devices, unless you feel like scoping the pins to find out which is which or hope their labeled.
These individuals are not kids. :fingers-crossed:
Excellent resource at the other site. Thanks!
But, I think I do not think I made myself clear regarding what I am looking for:crying:. I am not looking for info on how to JTAG a specific phone.
I am looking for 3 or 4 of the same model of cell phone that
I can pick up on eBay or similar for reasonable price (<$30/phone),
the JTAG TAP is known on the motherboard, and
it would be a bonus if the JTAG command set was known (besides the basic requirement).
This would allow me to make test run on one of the phones, then demonstrate the use of JTAG on the others.
The Samsung Galaxy Spica is a good phone, but I do not have the budget at $100+/phone. I need to find something cheaper. It does not need to be fancy telephone, or even smart phone - just have sufficient JTAG documentation.
If anyone has any ideas on what to use for this demo, I am still in need of a good idea.
You can look into any of the older HTC phones for this. I think that would be your best bet. I've done plenty of hardware repair, disassembling, reassambling, flashing, etc... on Android, & non-Android phones, & from my experience, the older HTC phones are the best. Specifically, concentrate on the GSM ones, such as for T-Mobile. Look into HTC myTouch 3G Slide (awesome little thing) , HTC G2 (one of the best keyboard phones ever), myTouch 4g, myTouch 4G Slide (overheating, self-destructing piece of crap), even the HD2 & the HD7. These are all devices that you can get for around $30 or so with a cracked, but still working digitizer, or some other kind of problem. Screens & other parts for them are very cheap as well.
Also, these are all known to RIFF Box. Look it up. You can do JTAG repair with these, & RIFF Box have all the JTAG ports labeled & documented. They might have some of the documentation right on their site, but I'm not totally sure. Anyway, check it out & see. I think this will be exactly what you're looking for.
Excellent! Thank you very much.
I have looked at looked at many commercial products, including RIFF Box. I narrowed the selections down the RIFF and ORT, but they are both very expensive for demonstration purposes.
I do love the fact that one can buy "jigs", "clips" or "adapters" (names change depending on vendors) which removes the soldering requirements for some of the phones. Except, these are still very expensive. :cyclops:
Again, thanks. I will look into these.

I'd go with Galaxy S 1 as it's really cool to work on and relatively well documented and demonstration on such stuff always looks well. But if you want something low-budget. I've seen JTAG pads on Nokia E50'ish stuff. Or try with some Samsung S3000's, these are pretty cheap. But I don't know how's JTAG there.
as @3ndymion218 told you , search old HTc .. also some Samsung that I think cheap could help too .
Samsung F480 , F490 , U700 , U900 etc ... some news Corby model also .. I think cheap .
I could help if you were near to me . I have 3 phones that I could offer you ...
Thank you for the further info.
Definitely will try to track down the HTC and Nokia information.
Samsung is a bit pricy as you said, but maybe down the road.
Again, thank you all!

Wirelessly Link 2 Phones to Run as 1 ¿(WiFi/BT)?

Code:
[FONT="Fixedsys"][SIZE="2"][COLOR="DeepSkyBlue"] First and foremost, Thanks for stopping by, you may become intreged if you continue reading my thread.
This Idea came to me a long time ago but I am unable to do anything with it as I am not a developer/programmer so I would never be able to create this on my own.
However, being the MadScientist I am (likely only in my own mind) I feel the only thing to do is to pass on the idea to somebody, anybody with the skill set, talents, abilities, or even the right friends list to make my dream a reality. So to the big idea.
I always had the cheap generic phones that were free with the contract, I would go through these phones like water and I came up with an idea that if I could put two phones or even three phones together and make them run as one phone it would be a pretty great phone [¿¿some Dr. Frankenstein ****??lol]
Over the past couple years I've always been interested in developing and apps in programming computers and how they work and operate so I now I'm in love with the expensive flashy phones and I currently have a Samsung Galaxy S6 and the S7 both Android 6.0.1 O.S.,
Both fully functional. (I'm afraid trying to customize ROM I'll turn my $500 BEAUTY into a fragile useless brick) (or even worse ruin the security features) because of my ignorance in Android Development.
None-the-less if anybody can come up with a way to join two phones to run as one without tearing them apart even if they only communicate with each other through Bluetooth or through Wi-Fi and can even Share/Clone to the partner phone screen through an encrypted nonbroadcasted network or connection that would be neat but it would be great to be able to share processors and sensors or leave on in my car in the parking lot at work and have it relaying a signal to the one in my pocket. I'd love to have them setup where I could use either number on either phone or share one number between the two. If there is any possible way this can happen I would really appreciate some feedback or I might just on a crazy rant and just happened to be the world's smartest retard.
I appreciate you reading the entire rant I appreciate any feedback positive or negative dream Weavers and dream killers is all welcome.[/COLOR][/FONT]
