[Q] JTAG without RIFF?

Does anyone know how to initiate a JTAG with out the riff box. Im more than capable of jtaging and have tons of tools as I am an electrical engineering student. Im not getting definitive answers from people online they all want me to send the my phone and $50 to them. I know you can get RIFF software from theyre site but I wont pay $150 for the RIFF box.

adam oulter has also suggested this is possible in a thread but he never tried it. he seems to have an idea of what you need. like a computer with a parallel port and software but i think he is trying to avoid the need to try it untill he has a way to force download mode and flash the normal way even with bad bootloaders or param.ifs. that is what he is actively developing and he wants the jtag to be a backup, and the riffbox service from connexion is a backup for his backup.

re:
I spoke with someone from mobile tech videos on youtube about jtagging with out RIFF he said "ORT Tool or maybe the SPT box but both require the same level of soldering. I must warn you though, the Captivate is most likely harder to solder than anything you have ever done. It's pads are .1mm in size and spacing and I know many electrical engineers that consider it extremely challenging." Im just freaking out because my baby (captivate) is dead. Maybe Ill just go play dumb at AT&T or blame it on KIES since Ive seen people say the bricked the bootloader with kies

if the phone doesnt boot they cant prove anything.
Dont blame it on keis. none of the keis updates touch bootloaders. so this should not happen. dont blame bootloaders at all.
ALL YOU SAY "it stopped working. i woke up, it was dead"
THATS ALL YOU NEED TO SAY.

That about sums it up... however we are exploring UART, I2C, Serial, USB, and all other methods of communications supported by the Application processor... maybe even tunnling though the call processor into the application processor... Basically, if we can get something into memory and then tell the processor to execute that code, we'd be in business.
There's about 25 total external pins available on the phone, two of which we believe make up the "EXT-I2C" bus. This would allow almost direct communication with the Application Processor and OneNand. .... Gotta find those pins.
There's nearly 20 test-points on the main-board inside the phone... 5 of those testpoints are likely the "OM" pins. If we can locate and apply 3.7VDC to OM5, then we can get the memory value OM=9 to change to OM=10+ which would allow booting from the external MMC card.
Research still needs to be done and the single diagnostic output we have located thus far is UART which uses the USB port... 619kohm resistor between pins 4-5, and read/write to D+ and D- on the USB port.
All of these things need help. You can help with your brick. Bricks will put out UART communications.

You can contact Connexion2005. He can JTAG your phone. it's been made easy now because I located the proper jacks and recepticals, and had a couple of receptical circuitboards made for JTAG.

Just to clarify...... my definition of brick...
1. black screen
2. unresponsive to buttons or button combos
3. appears to operate equally with or without the battery
4. 301Kohm resistor between USB pins 4-5 is not effective
If it does not meet those qualifications, then it's not really bricked. it just needs to have software reloaded.

Im gonna give the jig a whirl just in case. i think I got a waranty on my phone so if jig dont work I may just tell ATT its stolen, get a new one and use the old one for testing. Ill post results of the jig afterwards. Can I just use a micro usb wall plug for jig, I only got 1 USB-micro cable and I aint cutting it lol.

Which jig? Usb or uart?

I tried to just use resistors only and I had 270k and 39k ohms which reads 298.8k on my DMM and on mobile tech videos he said he did it with 295k so it should work......but it didnt. Ripped apart my ONLY micro usb cable cable tried to touch the leads to the resistors......nothing ://....soldering Iron is warming up gotta make sure leads are solid.

Well I guess its off to AT&T lol cuz it aint doin nothin right now. Its $125 deductible If i say i lost it so no candidate for a lab rat. Now i gotta rock this busted old cracked screen samsung solstice til I get my new one. I appreciate your help immensely guys, this is why I love this community.

The RIFF will run you closer to $225 after shipping as it's all overseas and they only ship with big carriers and ground shipping.

I've been pricing them at $190 on ebay.

This is true if you can find the parcel post China sellers. Good luck if you ever need support though or a return! There are definitely some defective boxes floating around that will have you pulling out your hair until your realize it's a RIFF hardware defect. One of my boxes I believe has an issue with i897 ressurection and has me thinking it's why I was successful on the the i897 I did a few days back.

Hi to all can someone tell me how to open riff jtag manager without box

I have a captivate board that you can have if you want it. I believe that it is softbricked. Though due to the busted screen I can't say for sure. I have a T959D screen that doesn't have a board which I have dremeled here and there to be able to accept the captivate board which you can have too.
If you can cover shipping it's yours or if I pay shipping could you help me with unbricking my SGH-I727R. I bricked it during a failed ODIN flashing of clockworkmod. For some reason the partition box got auto ticked the second time by the time I stopped my wide eyed loud inhale "OHHH NOO" it was all over.
I can get QHUSB mode. At least I was able to until the USB gave out. I had another USB board but it came from a corroded phone and during the cleaning I knocked off two resistors. I salvaged the same two resistors I knocked off from a the broken board. The person I got the phone from somehow managed to melt the USB cable to the phone, how this was achieved I haven't a clue.
Anyway I haven't gotten around to soldering the resistors to the board yet, I was waiting for a new soldering iron to come come in. It did the other day and I have to pick it up. Sorry for the rambling if you would like the captivate board to play with and or the T959D's screen let me know and we can arrange shipping etc...Thanks

[Q] [Help] Need to delete data on water damaged SGS9000

So basicly, I dropped my galaxy s 9000 in a drainwater hole next to my house and had to get it out with my shovel. I did so and obviously because it was raining, it got water damaged and also has dirt inside of it.
Since it was in there for around and hour with the battery still in while I tried to get it, Its pretty hopeless to try to fix it or send it to repair, particularly because I'm upgrading to SGS3 in a month or two.
I want to sell it on ebay for spare parts use but I want to first whipe all data off the phone, because it includes many documents like my paypal account history and emails on gmail. The problem is, if I try turning it on, the usual white text "Galaxy S GT-I9000" text shows up and in several seconds turns off. Even if I try booting into recovery mode, I just dont have enough time to hit erase all data.
So is there any way to whipe all the data off of it other than microwaving/purging it?
Thanks

Bump please help guys

I suggest you to put it in straight sunlight with battery taken out
hit thanks if I helped

I opened it and its completely corroded already and it would cost far greater than the phones currently worth to fix.
Anyway, as I asked, is there any way to erase all data off of it if it doesn't turn on for more than 5 seconds?

Identify and desolder Flash IC (or IC-s if there are multiple).
No problem if these are TSSOP-s (they usually are) - this can be done with soldering station and soldering braid.
If these are BGA-s then use heat gun and something to pick up the (very hot) IC.
Update: just thought that if you don't have time/tools to make it then there are 2 options:
1) just disassemble the phone, purge motherboard, sell what is left.
2) Find some mobile phone / computer / electronics repair shop where they can remove and destroy these Flash IC-s with you seeing it.

Before I do that though, is there actually any way I can possibly delete all data without destroying the hardware (If it isn't yet destroyed by the waterdamage ofcourse)

I know no way to destroy data in Flash memory without damaging other phone components or without disassembling if device itself is not operational.
Suggestion at the moment is:
* Wait for more feedback from forum members. Clearly there's a lot more experienced members than i here
* Meanwhile try to get phone as dry as possible - it may happen that it boots for longer time e.g. tomorrow

Indeed. Stick it in a bag of rice until you get a better idea

I will try doing this. I took the phone to my friend who used to repair mobile phones, and he kindly wiped the components with WD-40 on a toothbrush for free. He says that theres hardly any chance it'll work but it may eventually allow me to boot up for longer than 10 seconds which will be enough time to flash the memory.

Memory card, camera, sensors defective, serious problem, need help!

Hello,
so today I bought a second-hand LG optimus black that was soft-bricked and had a cracked touchscreen. Since I'm not new to android and know how to fix these things, I thought this was just another way for me to get a good phone cheap.
The problem is:
- after unbricking the phone, and installing official v10a software, there are issues with the phone - camera force closes, any of sd cards wont be recognized ("removed sd card, insert a new one" notification, never changes), the screen rotation doesn't work, there is no lockscreen, phone dialer has lags, and the screen turns on after 5-10 seconds. Otherwise it's ok.
With software v20b it also likes to hang up. Theeen you have to remove the battery
So I dissasembled it, and it seems to have short circuited somewhere on the motherboard (there is a brown spot on the metal motherboard cover plate).
I marked the area in a picture below (notice that it's right next to the SanDisk chip - i guess that organizes the memory, so it should take care of the sd card as well). Keep notice this isn't the picture of my motherboard, I will post my own photos a bit later..
Maybe it was waterdamaged, but the sticker on the battery is white :/
Please don't tell me to factory reset, or try other software or memory cards, already did that.
CWM won't detect memory cards as well.
I need any possible ideas to fix it.. do you think a reflow would have any chances to do the job? any ideas, please, will try anything..
PLEASE, help.

Some update. So I flashed software V30B, and it seems to get better - finally I get a lockscreen, and not in 10 seconds also, the accelerometer sensor is working, phone is smoother. FRONT camera is working as well, while in video call mode, yay! when turning on the camera, it has a black screen with all the buttons and camera settings, and a message that there's no sd card (although it's inserted :| ) and hangs up if I switch to front camera. Memory card still not detected..
Thinking of capturing a video to show you whats the situation.. Till then here are some photos to show you my beauty
P.S. don't be shy, guys, any ideas for fixing?..

Thanks for the reply!
Well I thought I would find more hardware technicians here, but whatever..
I downloaded the service guide for optimus black, and after looking at the schematic sheets, I'm 90% sure it's "SUB PMIC CAM POWER (LP8720)" controler that's failing. It controls the 5mp camera, microSD card and motor driver (vibration) power supplying. Neither of these functions are working on my OB. So no need for hardware hackers, nothing new they can tell me. So I'm thinking of ordering this pmu, but could you tell me guys where I could get it from with normal priced shipping? Shipping time wont matter at all.. Digi-key and mouser want to charge me with 40$ shipping, while all I need is a 2$ part

well mate, i have no idea..... i am just normal customer, if something wrong with my phone, and i cant fix it, i always go to official service center......
but, i hope you got some luck out there, happy shopping

Makes sense. Most people don't believe that ICs are a very sensitive component.
Obviously, I can't make a theory of what's wrong on that device, as I don't have it here.
Do you have a multimeter? On the service manual you might have somewhere what to do (e.g. where to measure voltages) if some functions are not working, or did you already try that? I know the service manual always ends with "replace pcb", as usually the technical support don't actually do the repairs, they just follow what's on the manual and send the old parts to the manufacter for repairing and reassembling, but it might help you understand if you really need to replace this IC. Is there any fuse nearby, for example? Remember, a short circuit would break fuses. You can check with a multimeter whether they're damaged or not (continuity test).
There's not much I can say, really...these are just some suppositions...
Good luck with that, man

I do have a multimeter, I'm kinda into electronics so..
Yeah, so I had a little break and checked the phone out only a few minutes ago.
The LP8720 is the problem, but its much more f..ked up than I thought..
I marked three spots on the circuit that are quite odd:
1. The place where IC U601 - LP8720 should be.
2. 2.2uH wire wound resistor L601 (MIPSZ2012D2R2 MIPSZ2012D2R2, 2.2 uH, N,2.0X1.2X1.0), not sure if it works, maybe it burnt out, my multimeter shows 0ohm on this one.
3. The place where capacitor C604 (10uF) should be.
I attached the pic of my motherboard, you'll see whats up..
The only place I can get LP8720 is alibaba.com, and the minimum quantity is 10.. that makes about 16 bucks for these. Would be worth buying and trying to fix? And another thing, it's named LP8720TLX-B, not LP8720TLX. Do you think it'll do?
I'm now thinking of taking it to a service center, ask if they could do such a job and how much would it cost..
Thanks for the replies, by the way!
Peace

Hey man,
keep an open mind
What makes you so sure that this IC is damaged?
Think: if the nearby components are damaged, then this IC may behave differently (or may not work at all). We don't need math to think this.
But yes, it can be damaged, but since this is the most expensive component, I think it is really worth checking the others first.
Anyway, answering your topics:
1. Everything looks fine. Good ^^
2. Yes, it's probably damaged. An inductor is supposed to have resistance, but not much. For this one, 0.23 ± 30% Ohm.
Source (datasheet): http://www.fdk.co.jp/cyber-e/pdf/CD-TCE070.pdf
3. Fortunately, this is an easy one. If in doubt, just replace it.
Now, for the headache...LP8720TLX-B and LP8720TLX might be the same IC, but the only way to know this is by comparing their datasheets.
16 bucks is a lot to pay for a component (yeah, it's 10 of them, but it's still a lot). But this is actually your call...are you willing to pay 16 usd for an IC? If it was me, and I was entirely sure it would fix everything, I would probably buy them, but then...like I said, your call.
I think it's worth taking it to a service center, but if they truly follow the service manual, they will tell you they need to replace the entire pcb. But I really think it's worth to try, you never know.
Good luck

Micro SD Slot issue

I've looked everywhere all over the internet to see if anyone has experienced this issue with not many answers. A while back my Micro SD slot would not read after a few events that I'm not sure which one may be the cause. I have a 32gb Sandisk Class 10 it works and was the proper format when I had it in the phone, it works fine in other devices and phones but not my phone. One event I had was that my phone got extremely hot one day when I was using it outside on a very hot day. Had to turn it off for a little while. But the other event is that I used the test 4.4.2 one click odin back in august. After those few things my micro sd slot never worked again I flashed to an official 4.4.2 using odin and have root but still not able to see the sd card at all. I want to know what I can do, phone is out of warranty. Is there a software issue or would I have to replace the Micro SD/Sim Slot. Is there anyone that would be able to fix this. Could I just replace the logic board, and If that is the case could I replace the logic /mother board with one from a tmobile phone, unlocked bootloader.

At least if it's an SD card issue, getting a replacement is as easy as going to http://kb.sandisk.com/app/answers/list/kw/microsd microsdhc/ opening a live chat and asking for one.

Hard to say. Stock 4.4.2 should read the SD card, no matter what was there before. (If my many-times-bricked phone can still read the SD card with almost stock 4.4.2, yours should too.)
or would I have to replace the Micro SD/Sim Slot. Is there anyone that would be able to fix this.

It could be the slot. I'd ask around for recommendations where you live. Some shops are great, some just ruin your phone. (I know - I owned a few before I retired. The "techs" who just wanted to start repairing phones, with no training, made "dime a dozen" sound expensive. [Not that I ever hired one. You want to work for me, here's a phone that doesn't work. You have 30 minutes to call me from it.])
Could I just replace the logic board, and If that is the case could I replace the logic /mother board with one from a tmobile phone, unlocked bootloader.

Probably. Not "you", though - someone who's opened a cellphone before, at least a few times. One wrong pinched wire and you'll need another motherboard. (The battery has enough power in it, when fully charged, to weld the plastic case to the wooden table - figuratively speaking. Pinch a wire with full battery current available to ground and you'll let all the "magic smoke" out of the phone and it'll stop working.)

...
Well I have opened up a few phones before its not that hard. As far as getting a local shop to swap the slot out that my prove to be a little hard considering were I live the people here are 10 years behind technology. Plus I think it would cost me as much as just buying a new logic board. What I really want is to flash a new rom to my phone I can deal with the 32gb of storage, but everytime I upload a rom and flash it from safestrap my internal memory goes to 0mb available then I have to odin reflash even when I load up via adb, when I restart the phone pass safe strap I just go into a black screen never does anything after that. Right now I'm just running stock 4.4.2 root

Well I think I answered my own question, just bought an OTG cable, I forgot about using a flash drive

Did I finally destroy my Nexus 6?

My nexus 6's charging port doesn't work so I only use wireless now
So I was messing around with theming my nexus and it started crashing and shutting down over and over again so I gave up on undoing it and went straight to recovery but when I was pressing the buttons in TWRP I fat fingered Internal Storage and wiped everything off of my SD Card.
So can I use TWRP's terminal to wireless ADB and flash a new rom onto it, is there another way to save my Nexus, or should I just give up and get a new phone?

I would say your best bet would be to fix the charging port.
Have you attempted the toothpick trick? It’s already broke so you really can’t do any more damage.
You can also buy a brand new charging port on eBay for $5, though I must admit I’ve never attempted that replacement on a nexus 6 so I can’t speak as to how hard or easy that is.

I suspect that changing the port will be hard. It is soldered to the motherboard, and soldering a phone requires special knowledge and tools.

Its very easy to solder and its pretty cheap to buy one. You can get a soldering iron from walmart.
