[Q] DIY JTAG flashing SGS2 i9100 using Bus Pirate/OpenOCD - Galaxy S II Q&A, Help & Troubleshooting

Hi xda-hackers!
<skipable preamble to question>
My 12yo son flashed an uncompatible image onto his SG-SII GT-i9100, which quite effectively turned it into a brick. It responds to none of the startup keycombos.
It is utterly unimpressed with the 301Kohm USB jig, that I learned about in another thread (http://forum.xda-developers.com/showthread.php?t=1746879 - Thanks a lot for the great information!).
It doesn't even show that a charger is connected (however I can measure a charging voltage, and the battery does get charged).
From what I've gathered, jtag-flashing is my only option. A riff box is a really nice and userfriendly device, that could help me just fine, but it's about 200 bucks, and I'm (hopefully) going to use it only once.
But I DO have a ($30) Bus Pirate (http://dangerousprototypes.com/docs/Bus_Pirate) lying around in my lab and some nice electronic tools (stereo microscope, cool soldering stations, etc.), so I am game to do some serious hacking and upon success, even documenting/sharing my adventure here.
I am a seasoned software developer and I do smaller electronics projects as a hobby.
</skipable preamble to question>
<question>
My question is:
- Since I am not a ninja in this area, I would like some pointers to where I can find a binary worthy of jtag flashing onto the device (I am guessing that I can use the stock kernel (fx. using the tool suggested here: http://forum.xda-developers.com/showthread.php?t=1110160)
- I know quite little of jtag. Is there anywhere I can read about the binary padding/enveloping of the binary image I need to flash? Just a pointer would be really nice.
- Have anyone else done something similar? How did you go about it? Where can I learn how you did?
</question>
Thanks a lot for a great forum!
I humbly and respectfully try to maintaing the high level of useful information, and I better stop now before I disrespect the "keep it short" rule even more!
Cheers,

Im in the same board as you, hard bricked/dead I9100, JTAG is my only option... Looking for information about this as well...

Look here, Google search, these guys & ask local mobile repair shops (you might find someone who does JTAG's close to you).
Unless you know what you're doing, forking out for the equipment to do it yourself will more than likely end with you being the owner of a 116 gram plastic paperweight (the phone) and a several hundred dollar box you'll never use again (the RIFF box). Do the smart thing & pay someone else a fraction of the cost to do it for you with their gear.

i got a buspirate too 3.5b and it helped me unbrick many devices and i got myself a smd work station and exactly well almost exact setup.and my knowledge is limited in electronics. my friend comes over to my place to do the work, smd and all other stuffs. did you unbrick it with a buspirate? or you use other tools.
time to ressurect this thread.

Peanut Gallery - Thoughts & Pole on GPS Hacking thread

Just a new thread so we don't spam the tech crew working on the GPS thread as it is growing at great speed, and spam is entering...
Discuss anything you want re GPS hacking, how cool it would to stick this up HTC's rear! LOL
Last time they include a chipset with disabled software!
So, hopefully in a month or so, we should see cooked WM6 roms for our hermes, and GPS enabled in them as well...
All i'll say then is it would simply be the best device, by a massive margin on the market!
Im in for finacially rewarding the person that gets a good working hack for the GPS or a cooked rom!
Keep up the excellent work guys! for what iits worth, its made me take up a C++ programming course, hate feeling left out and not able to help!!
crossbow and internal GPS on the hermes, that will be nice.....
excellent work so far.
Wouldnt a financial reward hinder the progress on the GPS ?, If the people working on it took the prize money challenge, they would start to keep all their progress to themselves and not share it with anyone else in case it helped someone else win the prize money ?
I'm happy to pay for the efforts of the people that are working on this project if thats what is needed to get it working, but i think this idea would be counter productive to everything that has happened so far ?
I help lots of local people with free computer setup and training and wireless network problems, but i never expect to be paid for them, i simply enjoy helping local people out, and i'm sure the people working on this gps project would be the same
This is the effort of quite a few guys.. not a race. I appreciate everybody's effort, and think that if there's a collection taken, it should be divided up however they see fit.
I'm up for more than $8, btw (how much is a standalone gps people?). And I would hope that our pooled $$ would help pay for some of the time and risk that a lot of people are making.
I would tend to concur with Mosser. XDA developers is about a community working together to enhance HTC devices. Offering a prize tends to take away from the teamwork since everybody is looking at the $$$. What you see in the GPS thread is the best of this community taking chances and putting everything they've got into a common goal. GPS is the prize here.
If you want to help, don't offer money, rather grab yourself a copy of the dumped Trinity Registry from post 390 (what we know applies to GPS is in post 108) of the "ideas thread" and start looking for a device that may have a connection to something named "VIRSER_COM". It's painstaking work going through the registry line by line but numbers make the job easier....
Hardware hack enthusiasts can start googling for a chip pinout (these show what each pin does and its location on the chip) for the Qualcomm RFR6250
Here's another thought:
Developers can simply place a "paypal donations" button into their sig if they'd like to see a few euros sent their way. If people appreciate the work, they can follow the link and donate. That way, teamwork remains the top priority.
Of course, you can always donate to XDA-developers too we can use all the help we can get!

I appreciate this is very basic and doesn't list pin numbers but better than nothing to start with.
Edit: found roughly the same thing again but this time it shows the interconnections with other chips (the JPG). If the the pcb traces can be identified and followed back it may be possible to determine pinout.
yeah, I've gotten that far myself. We need the actual Qualcomm datasheet on this chip, I believe, to get the pinouts. I'm gonna go and email their customer service dept. I think and pretend to be some big-shot engineer or something....

[REQ] Personal Dosimetry App - Help Writing

EDIT: I've now saved up $400 for the person who can help me get this running. PM me if you're interested.
I'm finishing up my bachelors degree in electrical engineering. My senior design project is to build a ionizing radiation detector from solid-state parts. The hardware is coming along well. What we would love to do is write an Android app to track/record/manipulate the data output by the sensor (via USB port preferably). Long term, I'm thinking the circuitry is embedded a phone case (like PowerSkins, except circuitry instead of a battery) and you plop your phone in, plug in the USB connector, and boom, you have personal and mobile dosimetry at a FRACTION of the cost of what is currently available (see Siemens Dosimeters-$1,000+ and then proprietary software costs). My project partner and I are crap at java programming *read-ALL programming*.
If anyone is interested in taking on something like this or knows someone who might be PLEASE PM ME. The deadline is coming up (mid-Feb), and while the software would be considered beyond the scope/requirements of the project it would really make it great.
Anything helps, even if someone wants to give as a shell of the code we could start with that would be greatly appreciated!
I should be starting another part-time job this month and would be happy to make a donation to anyone willing to help out.
Thanks.
Mark.

Moving to Q&A
That's quite an interesting design project you've got there.
My programming skills are quite lacking as well, so I unfortunately cannot help you directly.
Just one comment though; if you're going to be interfacing with an Android phone with an external accessory, I think you may need something like this: http://www.arduino.cc/en/Main/ArduinoBoardADK to handle communications between the phone and your sensor. Another option would be to use bluetooth as an interface.
Good luck with your project!

Thanks for the input. Ya, we're going to need something like that for sure. We're acctually planning on sending accociated energies with each event (in eV).

[Q] SOLVED ~ LOST ROOT - NO USB to flash via Odin

BANG HEAD!!
I have been flashing ROMs/Kernels etc for about a year so no a little. After testing Doris new 9.43v15 kernel I lost root, nothing unusual there, could get it back simply by dirty flashing PAC ROM again. Decided I wanted to go back to an earlier back up of Carbon ROM when I had Doris 9.43 earlier version running fine with no unroot issues. Used Hawkerpauls GS2 ROMnuke to clean my ROM then discovered nothing worked in CWM (just click and back to CWM first menu screen). So I powered off to which I got this message: root maybe lost - re root now yes/no - I clicked yes and then boot loop on Samsung logo. Tried to go back to CWM, CWM screen appears briefly with logo in bottom right, however blank screen and no menu for recovery.
Unfortunately my mini usb post is knackered on my phone, will charge but will not connect to pc. I have been using ADB wireless to connect with my phone but don't know how/if I can find this without phone switched on and running a ROM. Remember the ROM wipe I mentioned earlier - problem - NO ROM TO BOOT INTO! - Phone enters download mode fine though.
Only thing I can think off is sending my phone off and paying £50 excess on my insurance to get them to fix it, I have checked with a couple a local phones shop but they will charge £30 to fix it but say it could take 5 days! These are both last ditch solutions as I'm sure you can all appreciate I really don't want to be without my phone
I have searched XDA but can't find any solutions to this specific problem, if anyone has any ideas or knows where I meant find info that could help I would be very very grateful
SOLUTION:
Finally - it is done, my phone is resurrected and able to flash with pc odin once more. The solution - pay a guy £25 to fit new usb port!
What I have learnt:
If root is lost it is best to flash a new kernel with root before using gs2romnuke
That usb connection is really important so as to have access to odin via pc if all else fails
That some people are very good at laughing at others but seemingly struggle to laugh at themselves lol
Oh - and that M.O.P. = Mobile Odin Pro - I just worked it out all on my own haha
Thank you to those who have tried to help.
1.only an idiot flashes stuff without having the facility to use pc odin.
2.use the backup phone you have in case your primary phone develops a fault.
3.read the usb threads and order one from ebay.
4.or pay the repairer to fix usb port.
5.use mobile odin pro next time.

Thanks 'theunderling'
I thought Q&A was supposed to be friendly? Having looked at your profile and reading the posts that others have 'thanked' you for I can see you are consistently rude. I wonder - how do you think this could possibly help anyone? It's people like you that make XDA extremely off putting to new people who are trying to learn. I thought XDA was supposed to be a community based on being helpful? Were you never new once? Or maybe when you were you were bullied yourself and that's why you have now become one!
As stated in my post, I have come to the conclusion that I would need to replace my USB port, I really can't see for the life of me how using mobile odin pro could have helped when I had already lost root from within my ROM?
If anyone does have any suggestions for regaining use of my phone without replacing the usb I would be very grateful
Never mind the rude remarks buddy, because he still did try to help you, so forgive and forget, as for your problem because of the nuke script your recovery has also been wiped off and since you don't have anything on your phone to boot with(no kernel, no recovery or anything else for the matter) you need to somehow get a kernel or something inside and sadly for you the only working option is through a PC by using heimdall or Odin. So I suggest you read up on methods for replacing the USB manually or get someone else to do it, there are excellent guides by user keithross which might help you.

And also when I say nothing remains on your phone nothing will happen to the data on /sdcard and your external card and also to other important partitions like /efs so please don't misunderstand and panic.

Thank you, I'm being oversensitive due to being ill as hell due to a chest infection that just wont shift, and then this with my phone, just having one of those days. Yes, forgive and forget is a much better option.
That's exactly the kind of advice I was looking for from you and I will certainly check out keithross guide.
I think my post was extremely helpful.
1.Maybe youll think twice about doing the same again.
2.Get a backup phone.
3.Youll know what to buy and all the pitfalls about usb port replacement.
4.5 days will soon come and go,and £50 is chicken-feed.
5.M.O.P is a great app.
It is not my fault the way you do things,and not my concern about you missing your phone,and this is not an NHS forum......lol.
And Ive been accused of theft/breaking the law on here.......which was false.
Youve been accused of being an idiot.....which is not false.....so I think I have a right to be more aggrieved on here than you should.

1. My phone was rooted long long before my USB got effed. - I didn't realize your advice could lead to psychic abilities!
2. LOL - I have a back up phone, but its sh#t!! Its an old council work phone, horrible - really horrible.
3. I was never after your's, nor anyone else's sympathy come to that.
4. I found a local dealer who has the part in stock and can fix my phone tomorrow for £25 which I agree is 'chicken feed' in the scheme of things.
5. What is M.O.P. app ?
Our international friends may not know what NHS is so I will explain - NHS = National Health Service, I don't think USA and other regions of the world are as fortunate to have these services. Perhaps you struggle to understand the nuances of convivial conversation, are you apergic? If so please accept my apologies, my step son is aspergic and he has know idea of social norms. If not, are you narcissistic? That I would say is true !!!
P.S. - if you can't take it don't give it out, I could go on like this all week long as I really have nothing better to do because I am off work and ill!! I'd much rather just be friends as I'm sure you have a lot to give and I could learn much, just play nice after all this is all in a forum that states:
"Samsung Galaxy S II I9100 > Galaxy S II Q&A, Help & Troubleshooting ... [ Newbies][Experienced Users][RCs] New members friendly Q&A thread."
- which part of that was it that you didn't understand?
How are you aggrieved exactly, what is it that you think I have done - stated the truth about your behavior?
I dont know what apergic is......but im definitely sadistic.You can accept or disregard anything I say,and also in life you get criticism thrown at you....its life.
After my input,you may now be in a better situation for future standing regarding the importance of being able to resurrect a phone by having the ability to use pc odin.
Once you hang around here longer,youll see loads of other characters,like you,that are totally oblivious about the importance of pc odin.Then they act like they cant live without a phone.Question is,how the hell did they survive 20 years ago before mobile phones were in service etc.
Ive nothing against you personally,I just find it ridiculous how people like you,and the othets,take unneccesary chances with a device that they cant seem to live without.
And finally....at least that council phone works.....lol

LOL - for you:
Asperger's syndrome
1. a developmental disorder related to autism and characterized by awkwardness in social interaction, pedantry in speech, and preoccupation with very narrow interests.
I get your point, but really, there was very little I could do other than what I am doing now, which is to get it fixed! I reiterate - the phone was rooted prior to the usb getting broken, so, in affect what you are saying is that people should not root their phones if there is risk of not being able to connect to a pc, which means no one should ever risk rooting.
I think there is a place for your 'flaming' approach to people who don't know as much as you, but it certainly not here in a 'friendly, new peoples' forum. Fire away all you like in developers forums, I think you should stick to the rules here though and I suspect you would be the first to point out when others don't follow forum rules.
Your point about me saying 'I couldn't live without my phone' is ridiculous, it was just a figure of speech, if your car broke, would you not want it fixed asap? Not a lot of difference. I think you are making a big fuss over nothing, simply semantics.
I just think it's a shame that you feel the need to try to embarrass new people who are simply asking for help in a forum that is set up for just that Are you really that insecure? Is your self esteem so low?? LOL :laugh:
Maybe you could spend your time learning about the s2 than doing free psychological evaluations.You keep mentioning being rooted,whats that got to do with the price of cheese.Theres plenty of people on here have done absolutely nothing to their phone, and end up in the same, or worse situation than your in.
Also,since you think your so smart in sniffing about my posts/profile/state of mind, you could maybe hit the report button, and see what a mod makes of any rule infringements.
As for your "doing without a car" scenario, lets me just point this out;
I can use my wifes car I.e we have a backup car
I can do without my car for 2 months;I just done it a week ago
When I can actually be bothered working....I do it in my taxi
I here the iphone5 is pretty good
Edit:I mentioned mobile odin pro because most of the regulars on here say that it has less flashing problems/better success rate than recovery/cwm or pc odin.This has been discussed/argued about in the past.

Ooooo - did I get under your skin or something? Getting a bit close to the mark?? Just as you enjoy making your opinions public and having your say, so I am doing the same. Remember it was your choice to join in on this thread and start being insulting. If you don't like what you have got back maybe you will think twice about the way you communicate on a registered new peoples Q&A. You never know when that seemingly young little dog might bite back. If you don't want people to look at your profile then I suggest you keep it 'private' - there is a button for it, have a look. Isn't that line "I here the iphone5 is pretty good" getting a bit old now? I have seen you use it in quite a few of your recent posts, maybe you could think of a new one lol!
As I said to you previously, if you don't like getting it back maybe you shouldn't start in the first place.
BTW - your opening comments are ridiculous, what you say makes no sense - what point exactly were you trying to make anyway? Of course people come on here because they end up having problems, and they come to learn and try and find solutions.
Like I said, I have all week to continue this, although I agree with you that our time could be better served in actually helping others than bickering.
I have asked you some questions in this post, they really don't require a response as they are rhetorical (that means for you to think about) Now I suggest we agree to disagree, stop squabbling like school children and end this now. I am quite secure in myself, although I suspect your pride could take much more of a battering else you wouldn't have reacted so badly to my response's to you. And yes, I do indeed have the training and skills to 'psychoanalyze' as you say.
Maybe we can both stop taking our selves so damned seriously, as for reporting you, why would I want to do that, maybe just to give a moderator a good laugh? Now, shall we agree to move on?
That thread you mentioned earlier is actually a "sticky", which is slightly different than this area of the forum.Your topic is not in that thread, it is a separate entity.
Now,Im going to evaluate you;
I think that rather me calling you,or actually "inferring" that you are an idiot,would have received the same reaction as if someone else had said anything along the lines of
"Why are you opening up a new thread etc"
or
"Stop being lazy and search as this has been covered many times before"
You would view them comments are unhelpful, and maybe start doing free evaluations on them.
It is you that is more upset about our exchanges,as your veiled attempts at insults/abuse demonstrates.
You contradict yourself and if you dont like someones answers, you alter them to suit your own ends.
Your very,very easily wound up,and display a inability for rising above criticism.
Now Ive wasted enough time on this,so Im not commenting any further in your thread.

LOL! seems to me like it is actually you that is struggling with 'rising above criticism' and yes, you are right you have wasted a lot of time commenting in my thread, I'm sure it will give others a good chuckle though. You see, what you fail to understand is that I simply don't care about what you say about or think off me, I do however care about the next new guy that wants a bit of help and that's exactly why I'm prepared to stand up to your bullying nonsense.
Now maybe after all you do possess psychic abilities as you clearly seem to know what I think and would do in other circumstances than I have even considered, the thing is though, that no one else did say any of those things, it was only you!
And contrary to what you say the only other senior member that has commented was indeed extremely helpful and fill of useful suggestions rather than sarcastic criticism. I don't think this exact topic has been covered many times before and if it had, why has no one directed to a the relevant thread? Interesting huh
Have you looked at @Hopper8 thread about problems with odin. And have you tried cleaning the usb port. Different leads? Many things you can try and most if not all are in that thread. :thumbup:

Tried cleaning USB and there was a shed load of fluff and goodness knows what in there, also tried cleaning with a tooth brush and surgical spirit, still get failed to recognize USB error on pc though. I will look at the thread you suggested now. Thank you for pointing me in the right direction. Edit: I know the lead and ports on my pc are fine because they work perfectly on my wife's i9100.
Edit: Thanks, excellent thread by hopper8, I will be referring others to that thread, unfortunately nothing there that helps in my particular situation, just going to have to pay £25 to get new USB out in tomorrow as I don't fancy attempting it myself, looks kind of tricky!
This topic has been covered here more times this year than I've had hot dinners. Seems people's USB ports/boards are dying as the phones are getting close to/out of warranty.
As to why people wouldn't direct you to/give you a link to a specific thread, we have these two things called Google & XDA search. We don't spoonfeed stuff to n00bs purely because they ask to be/are incapable of doing the aforementioned searches. Why would I take x amount of my time to find a thread for you when you're more than capable of doing it yourself ?

I disagree, XDA is big and Google huge and after searching extensively I could find no conclusive answer to my specific query. That doesn't mean to say it's not there, just that I couldn't find it. I see on this forum time and time again new people struggling to navigate their way around these forums, perhaps if people were given a little more help to learn to 'search' maybe people would learn quicker saving the less tolerant purple on xda their precious time and effort to read what they consider to be tiresome threads.
Which leads me to my next thoughts, if your time is so precious and this specific subject has been covered so many times and is so boring, why would you 3 read it let alone comment??
Have you tried in adb to reboot recovery.
Or flash a recovery.img

I have tried to find my device using adb but because my USB port is knackered my PC doesn't recognize the phone which means adb doesn't see it also. I used to use adb via WiFi but understand this is only possible to do once the phone is switched on and running a ROM. Since I wiped using gs2romnuke I don't have a ROM to boot into, I have looked to see if there is a way to get adb via WiFi from download or boot loop but can't find any way to do this.
Thank you for your time and help Andrew, it is much appreciated

I have to say, no way you're getting it going again unless you can PC flash using Odin/Heimdall after running that ROMNuke script (I use the same script & have had similar issue once.) However, that brings me to my next point.. I was able to flash stock via Odin no problem in download mode. My USB port was working fine, because I'd recently replaced it. I know you rooted your phone before the USB port stuffed up, but moral of the story is, fix hardware defects immediately (volume keys, power keys, USB ports, whatever it is). You never know when you'll need them functioning correctly, as you unfortunately found out.
Not trying to have a dig, that's a friendly word of advice from my own experience.

[Report]Dump of phone led to hard-brick, [REQ]JTAG/Docs

Abstract
When dumping memory with adb, a device got hard-bricked by just reading it's content. Followup questions on the incident.
Best practice of dumping devices and Knox related issues concerning that process.
Inquiry of the availability of technical documentation. Advice on purchace of correct JTAG.
Some (probably already known) information regarding the disproportional illegal actions caused by Samsung. A hello to Steve!
Hello,
My friend had a problem when Samsung pushed an update she didn't ask for, she got panic, pulled the battery, which of course resulted in a
bad flash.
I tried to save her data, first by installing a different rescue partitions, but it failed so I guessed that the partition info was gone as well.
Since she had important material on her phone, I saw no other alternative then to try to dump the whole phone and try it from there.
The phone still answered on adb so I started to dump the phone.I usually always do a 2>&1 and when I got back the prompt quite quickly and the
file was small so I thought that I probably missed something in the command and rechecked it but it was good and should have produced a full dump.
It didn't spit out any error. Like when you dump a broken drive that shows I/O and you use the noerror flag.
Here I made an error since I should by now know how sinister SS is to it's consumers and I also blame the insane high quantities of morphine I'm
forced to take each day, together with excellent company that took my attention away from a normal dumping of a phone, done before Knox and
on my former devices that always been HTC. (Since the "real" work would be trying to restore the fs, spitting, hexedit etc).
So I restarted it without giving a though of the "rubbish" and it got overwritten. This time by with the size of zero.
Further checking showed no contact with the phone. And the phone had turned itself off and was not in the "Flashing error" (guess bootloader).
The phone was dead. Didn't react to the power button. The usual "battery reset". It was dead. Hard-bricked,
So I missed the size of where it stopped and I should chastise myself by learning all the options of tar and find or something.
So by a READ of a phone I managed to brick it. This has never happened to me. Ever. From dumping memory, FPGA, EPROMS etc.
Is this something that is known? Has anyone experienced this or heard about this? It was a READ. So I don't know if this is a flux or some
Knox related. In their confused post, where they talk about "e-fuse data" (Interesting that a flag needs a data-area).
Dumping a device
What is the practice of dumping a device? I know many does it using the block-devices but the raw-dumping of the phone?
I guess most use a JTAG? Can anyone, please, give me some advice on what JTAG to buy? There are gazillions of them.
Does the board even have pins or do I have to weld? Will the use of a JTAG trip Knox?
I want to take the next step towards the unenviable demise of Knox in one way or another, and here I want to raw-dump 2 phones, but if this
is common and a possible second E-fuse it feels a bit risky, and I don't want the block-devices, I want a full dump since I want (of course) to
re-partition my I9506 that has a too small /system (true). And I need to compare them not by the partitioning, but the full EEPROMS.
Samsung's "VIP-treatment" of it's consumers
We know that the "flag" is so much more. Besides the active intentional (and illegal) destruction of hardware (There are much more but most
notably is the WIFI that either stops to work totally or as for me reminds me of a US Robotics 56K modem) they also run malicious code with the
sole intent of sabotaging the OS to a unusable state and to make it work you need to reflash/reroot it to get to some kind if "normality".
SS is on deep water here.
Samsung's great transparency and cooperation
I've tried to get an address-range to avoid this "e-fuse data" but I get the prefab-answer that we all get on inquiries, from "Steve" @ "Fort Knox".
"I am sorry but we cannot divulge that information". That is on anything. Even the question that I think that needs to be answered, asked
repeatedly, from more then me, "What damage is done to my phone?". That will be asked by many next year when we claim hardware failure.
I got as far as "heavy damage" before "the crazy Swede" got to >/dev/null but I'll give Steve the holidays to gather strength because he will need it
next year that will bring SS interesting times indeed,
Documentation
I also looking for technical info. I tried at Samsung (HA!), but even Qualcomm doesn't have it available at their dev-site?
I find this so strange, since all that I done so far always had 250 pages of documentation from the timing of the stepping with the oscillator to the
intricate details about the thermal expansion so you can cad the marginals right.
Here I find none. Does anyone have something? Anything? Please?
I can't even find the info about the bootstrapping process, the bootloader, if the kernel is baked into it, since all companies have different
methods. I find the lack of information from the biggest mobile company, at the moment, very frustrating,
HI Steve!
Since "Steve" reads this about the same time as you, and if you don't want him to read a reply with a pointer, help that I really need right now,
I would be very grateful and happy for a PM as well. I have some ideas how to make it harder for Steve to read but that is better left our here
Thank you for any input I can get in those matters
/Abs
Mods, please don't move this post to "General" or "Q&A". This is a highly technical post and reading the rules of this board it belongs here,
where the wizards sits, read and can, if they wish, enlighten and help me moving forward in my project.
If not here then please PM me and point me to an another technical section where it "fits" better, please
First confirm its hard bricked (no led , doesnt boot in any fashion, if it "vibrates" or shows anything at any point on the screen then its not bricked) and is currently in Emerg. Host D/L mode. You can do that either using lsusb or dmesg | grep usb in linux or check what Windows reports for the COM port. In both instances you should see QDL download mode. I'm pretty sure no one has figured out how to activate the "Boot from SD mode" or found what to short in order for the T-Flash method to work. Though they do both exist for our device, confirmed by the strings found by querying the output of using an invalid signature.

It's actually gone to the shop now (and then the graveyard that Samsung soon need to widen).
But the answer was no, nothing. Didn't react to anything, It was totally black. Like it would be turned off without a battery.
The serial port was blank. Not a single bit back. It was a brick.
There I would need a JTAG, but what to buy?
I hope they can save some of her info. Sent an note with her with what I wanted back from them (A dump if possible). But my guess is that they
just connect it. Dead? Ok. Return to Samsung. Give her a new. But she rather have a Ericsson SH688 (I must find it. It's somewhere...) and her
data back.
Oh poor Samsung, besides this "nobody, clueless and crazy Swede" (I'm adding each "deep analysis of me", to my designation. Clueless was today's ) they got on their neck, they don't know who they angered. They should check where people work before they pull stunts like this.
I thought that was the intent and purpose of the "unique certificate"? Now they just confuse me.

I'd like to introduce myself...

Well, this is an attempt to possibly access more information. I may have read somewhere that stated in so many words, a little participation, or, even just an introduction, may get you a long way here on XDA. Now, whether or not there's any truth to this, isn't really of any importance. What's of importance, is how unimportant one may consider what someone else views as important. Setting that aside for a moment, what about the the truth that's actually quite commonly found leaving the liars mouth? I'll give examples in a moment but before I do, ask yourself if one were to actually tell the truth but believing it to be a lie, would what was said be considered by you, to be honest? I mean it is the truth, just delivered with dishonest intent, right? I am a newb, on an iphone 6+...iOS 11.2.5 just until I can put together the $100 deductible for the MOTO Z I dropped. I haven't been very active in these past years being with Verizon, but I wasn't very active before i made the switch. I was a DROID X2 bricker and I will always be. Just recently found a junkyard of old phones, that I or friends bricked, or dropped without insurance, cracked screen, no battery, etc.
What I am and have been working on, with no success is an On5 SM-G550T (A.R. MMB29K.G550TUVU2AQC4 samsung/on5ltetmo/on51tetmo) updated to 6.0.1/MMB29K/G550TUVU2AQC4
FRP and can't enable debugging with anything I have found thus far...I have used the enabler but may be flashing the wrong files as I have come across plenty G550TUVU1?????? but nothing found for G550TUVU2??????? I'm sure my recovery (TWRP) file is correct but until I can enable USB it's really not doing me any good. Any chance of someone(anyone that made it this far is respected!) possibly shootin me instructions or even just pointing me in the right direction. I have attempted flashing with odin and even OTG with other suggested files. Objective is to bypass frp by enabling debugging and flashing stock 5.0 firm so I may then install twrp and depending on my mood and position of the moon, maybe a super user and some ROM tryouts. You guys are awesome, even if you decide not to help. Developers, my thanks only goes so far and so do the rest of these words, so Ill be about it soon and wont talk about it now. But seriously, hat's off and I appreciate the countless hours, painful blinks and most importantly, the late arrivals and drop offs associated with such sacrifice. Thank you!!!
