Question about JTAG and ubrickable mode - Captivate Q&A, Help & Troubleshooting

i hard bricked my captivate and i took it to a lab near my house that fixing smartphones.
i dont really understand what the explained me but they said they can fix the phone but there is 50% chance that the procssesor will be locked and then the phone is will be completly dead.
i forget to ask them what method they going to use but this is sound normal?
i read few things about those methods but i never saw some one the talking about that 50% chance .
there is really a chance that my phone will be locked? or they just dont know how to fix that adn they are preparing me for the worst O=

Jtag requires to solder 6 very small spots. It is possible to damage it. To be honest Try to get Unbrickable Mod since it wont ever hard brick again. At any rate contact Adam (one of the devs in Unbrickable mod) or Josh (mobiletecvideos.com) and get them to do it. I know Josh had something like 99% success rate on Jtag. Unbrickable mod is easier to get as well.

No offense to that shop but if they are giving you a 50% chance they are not experienced with advanced recovery on Galaxy S phones. As mentioned UBMOD or JTAG are great recovery methods for a bricked Galaxy S phone. Both achieve the same goal and UBMOD adds the benefit of recovery via USB if you re-hard-brick it and are familiar with using Linux to use the Team Hummingbird resurrector. Contact my self about either recovery or Adam about UBMOD. Also the above statement is correct literally 99 out of 100 Captivates are repairable when hard bricked. They have the highest rate of success in my opinion as the hardware is very solid and typically doesn't fail...

the problem is that im from israel and the shipping will cost alot.
i try to take it to another store.
thanks.

Ok well good luck. Once again though, I'd check to ensure they are familiar with the model and either procedure.

G1 Bricked.

no doubt this isnt the first thread on a bricked G1. anyway, my brothers had this G1 for a year now, and its been bricked all this time (goes to bootscreen and thats it, cant get into recovery, cant into the screen with androids on skateboards (quick boot?), just stays stuck on bootscreen.
now he has said he will pay me if i fix it. i have no idea what he was doing when he bricked it, suffice it to say he did something stupid.
for the sake that i might have $50 by the end of tonight and be able to lord it over him when it comes to any phone related faults. how do i fix it?,
(i dont know how to jtag, it looks too complicated and rather expensive)

It's actually very cheap if you build the gear yourself but it might be too complicated if you don't have experience in such things. Anyway, it's the only way to fix a brick so try it or don't, but you've got no other options.
meh very well, how would i go about jtagging it? i saw this video on youtube where they connect this thing to motherboard and connect it to computer and do some next level geeky ting.
The information you seek is here:
http://wiki.cyanogenmod.com/index.php/JTAG_DREAM_AND_MAGIC
It requires some quite intricate soldering.. I wish you luck.

ditto & ditto.
Each processor or epprom on a circuit board has a programming interface for programming at a hardware level. Usually you will have to track down the datasheet for that chip and find what's used. ISP, JTAG, etc... Then you need a programmer. As was said you can build one, or probably buy one on ebay thats compatible with your chip. Once thats done theres usually either a port for jtag to hook up to it, or you will need to track down each pin to program it. JTAG us usually 20 pins but I'm not sure of the chip your using. Once thats done you hook up the jtag programmer to the jtag pins on the chip. Then use a IDE (integrated Development Environment) or flashing software to flash a new rom/hex/file to the chip to restore it to normal. This is the highest level of geekyness and how they basically hack playstations on xbox's. If your into this sort of thing I highly suggest you hang around. www.allaboutcircuits.com I'm sure some of my info is wrong but thats the basic jist of it without fact checking.
Post the video of what your trying to do and I may be able to do it for you. I have some JTAG programmers already but I'm not sure if their compatible. If your running an ARM chip it probably is. If not, probably not.

[Q] - Change ROM => Boot between start screens

Hi,
I own a Captivate on Rogers (Canada).
I had the ROM Firefly 2.6 (or 2.4) and decided to change to something quicker or at least different.
I decided to put Cyanogen 7 on it, because many people told me to.
I succeeded in installing Cyanogen and it worked great, easy to use, fast, ultra fast reboot, nice looking... but not all the software I was looking for.
So I decided to change again to a JVQ SIMPLY.
Put it on the SD, move it to sdcard via Astro under Cyanogen and reboot in recovery mode to install update from sdcard.
It wrote that it was ok, and needed to reboot.
Now the only thing I have is "booting" from
- the very first screen with Galaxy S I9000 on it to
- a second one with Galaxy S Cyanogen(mod)
I can access the screen with the little android guy in the public works sign, yellow, with Downloading... and Do not turn off Target!!! (did it trying hard reset).
I couldn't reboot with 3 buttons (tested many methods), the one with Odin, I never ever succeeded with that one, and it continues changing from a screen to another without stopping but if I remove the battery of course.
What can I do from there?
Thank you for your help... again...
Just for clarification, did you do the Odin One-Click to stock? If you can get to the download screen (the yellow sign / "Do not turn off target" screen), you should be able to flash back to stock.
I tried the Odin 1-click, but I think that it won't work right now because I can't access the administrator rights (from work).
I must try from home tonight.
Will it remove everything like the fact it is root?
Thank you for your answer by the way.
The lack of admin rights is very possibly why it won't work. There's also the chance that without admin rights, you're not able to install the samsung drivers. Either way, waiting until you get home sounds like a good idea.
You might be able to do the Heimdall one-click without admin rights, but it would probably be wise to read up on that one first as it's in Beta right now.
The one-click to stock will put your phone in the state it came out of the box, but leave all your personal files on the phone. You will have Eclair 2.1, unrooted, straight as it came from (in your case) Rogers. Any pictures, music, etc you saved on your internal sd card (not the microSD) will still be there, but you'll have to re-root and reinstall any rom you want.
Ok, so I tried different Odin (one click) I found here, and the last one, from here:
http://forum.xda-developers.com/showthread.php?t=1126704&highlight=odin
I flashed the PIT only, because I didnùt know what to put where... bad idea, now my phone doesn't switch on.

Sorry to have to tell you this, but it looks like you might have fully bricked yourself.
If you are still under warranty, you can try to send it in for warranty service. If not, or if you aren't comfortable taking that route, look for a member named connexion2005 (or mobiletechvideos on google), who can do JTAG service for you for $50.
The JTAG thing is the special cable made from special resistor, right?
Or do you mean it is hard break and only expert can do something?
Thank you very much for your help and your support.

You're thinking of a Jig, which is a set of resistors that kicks the phone into download mode.
Unfortunately, you need JTAG, which is a special service that rewrites the bootloaders to the phone so that it can boot normally. That's something that you either need to be fairly knowledgeable about electronics to do yourself, or something you'll need to send in (to Samsung or mobiletechvideos) to have fixed.
Yeah I thought of a jig...
Ok, I will try the warranty, perhaps it is so much messed up, they won't find anything...
I will let you know.
See you.

Good luck - hopefully your next time around with custom Roms will go better.
I did many, many things with WInMo and never encountered any brick (sometimes I was close to the cliff, but never fell).
Since I have this Captivate, I not sure to really like it, I am fond of android either, and I don't take enough time to read carefully each post...
I think it is time for me to take an iphone...
Although you could do that, I think you'll find if you give yourself a little time with Android you'll come to really like it.
Don't get me wrong - the iPhone is a well made product. But it is one thing, and only one thing. Android devices can really be anything you want.
But that's my opnion. Do with it what you will.
People like you are gold, taking time to help newbie with the always same questions, don't selling android is the best (other are selling ios is the best), ...
I'll see what kind of hone I can find, because the Atrix was a cool phone I liked, and I always liked HTC (qtek before)...
Apple is expensive!!!

Thank you. I'm just trying to repay the many favors everyone else here on the board has done for me in the past.
Definitely look around - if the Captivate isn't working for you, there's plenty of Android phones that are every bit as good. I've also had good luck with HTC phones in the past, and Motorola's not bad, either.
And yes, Apple is expensive. Can't argue with you on that one.
This might be stupid question but, is your battery charged ?
Hi,
aww.W.T.F, I hope so yes... it was on the usb for hours... you put me a doubt... I need to check now!!
I asked Rogers for warranty, they charge $35 for an exchange, and 5 days to wait, I think this is a little bit too much. But I will do it.
What I discussed with a guy is that I will finish my current subscription with Rogers and take the HTC Sensation with Virgin... Another try with android, to follow jmtheiss.
I will continue to let you know about how it goes.
If my profile is closed tonight, this will be because I will be too ashamed because I had an empty battery...
P.S. Ok it is not the battery... I'm waiting for my new one and will send this one to warranty (I'll see what they can find or not...).

[Q] how many bricks?

Would love to know how many people have bricked their notes.Is it just an odd few or are there 100s.Has anyone had repairs ,unbricked or replaced by their carrier?
I too would like to know this.
Ok
Soft brick? I am sure there are tons, me included, a proper brick brick after which you use the phone for a coaster, don't think so many, though I have one of those too (shattered display).
Correct me if I'm wrong but I thought it was nearly impossible to brick an Android phone? When I was learning to flash and so on with my SGS, I certainly bollocked it up a lot of times (ah... misadventures with using incorrect files...). I have always been able one way or another been able to get back in and mend the damage.
With the Note, Download mode is hardwired in so I thought it would be difficult indeed to properly brick it. That said, I haven't done much with the SGN yet since it's my daily device and I leave it alone. (@torqu3e, I don't think shattered screens count towards the typical definition of 'bricked' do they? I thought it was a software f-up )
When someone says brick, I think of a phone that just won't turn on and is completely useless...but in many people's cases recently, the partition tables have been messed up and the phone is as good as useless. It no longer holds its function as an Android device. So yes, add me to the list of "bricked" Notes out there.
I got a hard brick! :-( It's in the shop..

Sharing wat you did to brick your phone might help others prevent it.This is not only to you but to all who's gonna report here....
I was talking more about bricking from flashing that dodgy ics ROM.Anyone unbricked or had it fixed under warranty.
Add me to the list. I bricked when I flashed a kernel that messed up the partition tables. Its at the service now.
one more to the list
i need to sent mine to the US
I faced a soft brick when i was flashing ics betas (mobile to pc screen) but fixed it by flashing stock rom then flashed back ics!

In ODIN while trying to flash CF-Root ICS progress bar froze on Factoryfs flash and after 30 minutes I unplugged it. Phone at this point wont restart turn on or anything. Didn't respond to JIG to go into download mode so I took it to a service center in Southern California. They tried fixing it with JTAG and it didn't respond. It is Kernel related. I got some sort of good news today from the service center that they may have found a solution and are receiving a new tool to do the trick. I am crossing my fingers and waiting for the next phone call from them that if they could get my phone up and running again!!

[Q] Captivate boots to black screen but capacitive buttons still work...

Hey guys,
So I'm planning on buying a Captivate used, the problem is that the phone will not boot. The seller says that it will go to Download and Recovery menu so I'm thinking this will still work.
Any ideas on what state this is and if it's salvageable? In need for a new phone so I'd like to get the Captivate at a good price.
Thanks a lot!
Hi, the phone is still very salvageable. If the imei is corrupted then the phone wont be much fun unless you get that repaired but I love my cappy, very fun to modify. I guess it would help asking whoever what happened when the phone went all crazy.
From the land of defrag
Thanks for the response, I missed something that he said. So it does boot up, goes past the S logo (boot sequence) but then stops at a black screen.
It stopped working after CM7 was installed and he reset the phone from boot recovery to factory settings.
This is easy to restore via odin. Should take you 10 minutes.

just download and flash any Odin odin click package with computer running windows and you will get the captivate running
I got mine because the owner was not able to enable installation of non market apps.
Thanks for the support. I think I'm going to buy this! Any guides on how to restore a Rogers i896 Captivate with Odin?
Just to add, the oneclicks, specifically the ones with bootloaders be careful using, a bootloader botch will permanently black screen your phone and a Jtag is the only fix. As for guides, just read the hell out of the captivate section in xda, specifically for Rogers users, go into the development section, find Trusselo and his page on the i896, read that, should get you by.
From the land of defrag
jtag is NOT the only fix and is antiquated on this device thanks to Adam outler.
The captivate was the first device that the unbrickable mod was perfected on, it fixes a brick like jtag would, BUT if you were to brick again, its the exact same repair process with jtag, with UBM however once the hardware modification is made its a simple process of running the resurrector program on your pc and flashing new bootloaders onto the phone, the user can do that Themself over and over without having to send it in again.
lol, ok ok, you are right, however, i was just making the notion that if something really goes bad on a flash, especially if you just bought a used phone, you wouldn't want to send it away for the unbrickable mod or connexion2005 Jtagging as soon as you thought you were going to fix it.
From the land of defrag
Connexion2005 also offers unbrickable mod at mobiletechvideos
I get your point, just informing the newcomer
Cool, I didn't know that. I'd still prefer jtag, Joshs Kung fu is strong. Never hard bricked the phone yet, running a kk4 build, wont worry about bootloaders again. waiting for the S3 for ICS.
From the land of defrag
Thanks for all the input but you've got no idea how overwhelming this is for me. I need a new phone and this is coming at a cheap price, you think it's worth it for $80? What are your opinions on this phone?
yes, i think 80 bucks is a good deal. The captivate is a fun phone to use. call quality is good, battery life is great, screen is bright. once again, i love my cappy.

I got the phone for $70! But when I try to reflash to stock, Odin will not detect my phone...
I'm really new to this stuff so I have no idea what to do next?
Thanks
read this
Got everything to work with Odin but after a reflash of stock I still got the same blank blac screen after the boot sequence "Galaxy S" logo
What stock firmware are you flashing?
Rogers i896 2.2. The phone wasn't on 2.3 yet.
So confused. The thing boots and all but just wont get passed that blak screen... I've reflashed to stock 2.2 at least 10 times to no avail.
I can go into download mode and recovery mode so I don't think I need a jig unless there is something it does that I'm unaware of.
Any thoughts on what's going on?

wipe data/factory... later on, the os freezes and require reset

I got a note7000 offer at a bargain price; half the price of the original... the idea is that the guy is selling it as fault emmc bug. He told me that wiping the data - factory reset caused the problem.
The phone works from times to times he said, is still partially functional, thus he still asks for the price of SII for it, which he wants to replace with.
My question is:
Is the emmc bug permanent? I want to buy it cause is such a awesome screen\phone and i cant afford one from retails at full price. My plan is to downgrade from ics to gb with safe kernels and hope it wont brick with odin as unsafe as it is already.
Don't buy it. He is selling a bricked device for half the price (I wouldn't pay that for a used but fully functional right now).
And you will always get problems with it in many different situations.
Its risky for me, but also rewarding. If you'd seen this particular phone, is almost brand new. He told me it wasn't used much and that is visible on the over all aspect. And god, i love amoled screens, even if pentile is infamous.
Could you describe what you mean by being bricked? -> the phone boots and installs stuffs, but from time to times has the flaw of getting stuck -> require reset.
Its on the way
ps. I trust that if i had this stuff happen to me, coming from a samsung product, i would be able to get it fixed somehow.
Congrats: you just bought a bricked device. I guess he used the repartition workaround which reduces available capacity.
He didn't do the only real fix: replace motherboard in Samsung Service Center.
If you read here more before buying you would understand my "do not buy". Now you will learn later.
And he didn't lie to you - he told everything about the condition.
If you want to learn now while waiting for it, start to read about bricked devices here, about hg42's repartition thread etc. You might need it
Well, wish me luck. I'm gonna follow the steps from around the topics here.
I just hope i can watch movies, and pictures, and browse the mail... then he can get stuck but just a little.
I got an ace on my sleeves though. I can test it before i buy it... any advices, maybe doesn't even have the bug, how i notice
that ?
I'm gonna try these steps on the clip from rootgalaxynote:
youtube - hDtTNDVcTF4
If it doesn't work, i'm screwed cause i do not have a replace phone atm.
Following those steps will only mean that you won't brick it again... and anyway that is really outdated... When you've had enough of constant freezes then you will probably want to try a slim rom such as Slim Bean 4.2.2
I just purchased a n7000 from a guy on eBay for $350.00. It has the Ultimate rom installed in the screenshots. This means that it should be fine, right? I should receive it this week sometime. I bricked my i9100 back when the brick bug first appeared so I'm kind of worried about this.

Thanks for replies. I dunno what to expect. It is worrying, but probably i'll return it back cause is not worth the money if you put it this way "unusable".
He said to me to add a new sd card,,, i guess here is where he was just too honest. This confirms that there is actually a permanent damage to the hardware, especially the hefty 16 GB of memory.
My friend has the bug and he did the workaround , The phone freezes when you turn on bluetooth or wifi , And also the internal memory is low , but good luck with your's btw "restarting it from time to time" seems suspicious though

Apparently that was a slight misleading. On itself doesn't restart. I got the phone right now. Is so huge even an elephant could use it.
Only freezes when i try write something thru usb cable. The ram is smaller, only 5 gb.

Really? Then it might be double-bricked and double "workarounded". Each time lossing about 3 GB...
When I close my eyes I see the grinning of this a--h-le who sold it for real money.

First off, i'm in a bit of trouble right now. As you can guess, i can do something about it, cause beyond this is the morality of getting into a mess on someone's fault. Now that has to be decided, as long as is not mine.
This guy told me it is partially usable, add a card, try fix it yourself. At 190$ i expect to be better then a S1 or nexus s which might easly outmatch this phone. If is a matter of pride. Just keep it to yourself.
Either i give this guy a bad review as is a site as amazon, where user feedback is noted, or i return it back myself. Is not the holly grail, is just a phone.
He told me is not permanent damage.
LE: I got some good news and bad new:
I cannot add videos, it simply doesn't write. It doesn't freeze my phone anymore, this time i'm using samsung kies. Good news, i can write photos and songs.
I'm half way there in trusting this guy that with a sd card, the phone will work just okay in installing stuff.
On the other hand, i dunno if the internal storage is damaged; can i install jelly bean? or change the culprit kernel? or should i live with it as it is.
the seller has a no return policy. so ur actually screwed. you think the seller is a noob and that he didnt know about the fix. sometimes being too wise makes u feel and idiot in the end.

How was his random ranting relevant to this topic?
So what do you think... flashing a new kernel and formating the sdcard do any good?
I may have a different term for bricking: When used in reference to consumer electronics, a "brick" describes an electronic device such as a smart phone, game console, router, or tablet computer that owing to a serious misconfiguration, corrupted firmware or a hardware problem, can no longer function. The term derives from the vaguely cuboid shape of many electronic devices (and their detachable power supplies) and the suggestion that the device can only function as a large, heavy object.
As far as i see, this device has stuff installed on it, and i can't figure how he did it.
recommend me a memory error checking app if u know, please!
Flash a safe kernel and flash a new ROM.. Try that and if all works good we´ll continue..
