it is working 100.. i created one usb with 300k resistor
[Galaxy S I9000 General] SkOrPn:
Did it work 300k? I ordered through Alibaba and a Chinese bussiness man sent me 300k instead of 301k claiming 301k is a specialty item that he could not get right away, so he filled my order with 300k instead... Lol, I told him that would not work and he apologized and then told me to just keep them for free then. I said OK... ;)
[Galaxy S I9000 General] BeyHock:
were i can buy that online in uk, that resistor?
[Galaxy S I9000 General] BeyHock:
What kind of resistor i need to get donload mode?

http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=66690&k=res 300k ohm 1%

which one from these i need?

Thank you very much.
[Galaxy S I9000 General] CommanderTux:
I should choose the cheapest!
[Galaxy S I9000 General] BeyHock:
must it be 1% or other % it must be? and also the same about watts?
[Galaxy S I9000 General] theexx123:
Bah, both cables (different brands) i've tried are so full of glue it's litteraly impossible to get away everything.
[Galaxy S I9000 General] aGalaxySfan:
Get the cheapest. Power and tolerance won't matter with ohms that high.
[Galaxy S I9000 General] MoWeb:
I would like to thank the OP for this information. I've had my t-mobile Vibrant for about 1 week and didn't want to flash any custom ROM because of the troubles I saw getting into download mode. This way is so much easier and works every single time.

1. Bought a breakout board here:

http://www.sparkfun.com/products/10031

2. Bought 301k ohm resistors here:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150487465984&ssPageName=STRK:MEWNX:IT

3. Bent the leads on the resistor using needle nose pliers (s shaped loops) and inserted into holes ID and GND on the breakout board.

4. Soldered top and bottom to make sure the solder went through the holes.

5. Clipped off the ends on the bottom.

6. Covered resistor.

7. Done...

Here's what I made and I can't solder.
[Galaxy S I9000 General] SkOrPn:
As GalaxySfan said just get the cheapest ones. I found that my local electronics shop Walker electronics here in ABQ NM had the best ones although not so pretty, but they were only around $0.08 cents. I purchased 5 really nice looking resistors online from Digikey for $0.11 each and they came in packaging that took half the forest to produce, so not to pleased about that, and the tolerance is all over the place, but the cheaper, not so good looking ones from Walker are all exactly 301K which is surprising. So long you meter out above 298K and no higher than 304 you should be ok is my guess. I have not tested this yet to see what my phone responds to but plan on it some day.

Yeah what he said... lol
[Galaxy S I9000 General] Casio1987:
It worked for me with a total of 297K ohm. Less wouldn't work for me, because it would show the corrupted semi-bricked graphic.

It doesn't matter. The less tolerance, the less the offset in range of Ohm of the value in theory. Watts don't matter, since there isn't going much power through it.

Same here, not impossible though. Just be patient and cut it off safely. It could take a few to several hours.
[Galaxy S I9000 General] allotrios:
I thought I was going to have to use this today but in the end I managed to get my phone in download mode.

It may be usefull to try what I did if you are stuck to the screen of death icon (PC--!--Phone)

What I did is pressed up volume, kept it pressed then pressed down volume, kept it pressed and then pressed power and kept it pressed. I did not release when the no connection icon came back but kept all buttons pressing until the icon had gone and come again and gone.

Then I took the batter out for a 10 seconds and put it back in. I then tried the usual combination for download (vol down, keep pressed, menu, keep pressed, power keep pressed) and DL mode appeared.

If keeping up+down+pow combo pressed for a few cycles doesn't work, try down+menu+pow for a few cycles, then take battery out.

I had a lot of scares today. At some point the phone would not show anything and it was actibg as if the power on button was broken. Eventually even after that I got it into DL mode.

This is one hard phone to brick but I think I will make one of these usb thingybobs just to be on the safe side! :D
[Galaxy S I9000 General] bader1980jo:
full bricked

any one manged to repair a fully bricked galaxy by any way???
[Galaxy S I9000 General] thanys:
no object can be deleted
[Galaxy S I9000 General] Pat123:
I would like to know this too. My phone is fully bricked. Doesnt power on, does not show anything on pressing any damn thing. Is it worth trying this jig?
[Galaxy S I9000 General] TheBeano:
Basically no, it requires the second bootloader to be working and if that is not working there is nothing on the screen.
[Galaxy S I9000 General] othermark:
Be sure you try with a charged battery if you think it's fully bricked. Even my wifes' nokia appears bricked if the battery has no charge. But yes, if the boot loader is gone, then the phone will be unable to boot into download mode.
[Galaxy S I9000 General] SebyM:
TheBeano you are brilliant.

I was stuck in the reboot loop and couldn't do a thing with the phone.

I rigged up a variable resistor (varistor) and measured the value to 310K, the added two wires to make the leads longer, connected one to the bare back metal of the sim card holder (in stead of pin 5) and one to the pin 4 of the usb connector and voila, instant download mode !!!

Now flashing :)
[Galaxy S I9000 General] c0caine:
So i managed to brick my phone (galaxy gt i-5800), there's no response to anything, usb cable, button combo etc. Nothing can be done i guess?
[Galaxy S I9000 General] Azzelio:

homemade JIG can be a solution for me?

i don't see at least the white Samsung logo or the "PC ! Phone" logo on the screen

my device will not turn on, I see only black screen
[Galaxy S I9000 General] vasilgatev:
my phone died too, but phone is it lg gd540 optimus

my question is it. can this combination/ JIG/ be used on my lg optimus or must be change resistors.... or pins numbrs , because my phone died. No download mode with buttons.

thanks in advance pleace help me.

sory but i d'nt fоund nothing in lg section :mad:
[Galaxy S I9000 General] TheBeano:
I had a quick look at the open source for this phone (I assume it's GT540) but there is nothing like the same sort of arrangement on the usb/serial port, so you are stuck with the phone's builtin factory reset methods I think.
[Galaxy S I9000 General] Azzelio:
i made jig cable whit potentiometer...not work....

What can I do?
[Galaxy S I9000 General] allotrios:
hmmmm

mine was absolutely dead for about 10 minutes

the screen would not come on at all as if there was no battery in the phone

i took the battery out for a while and pressed all shorts of button combinations with the battery off (desperation)

i also plugged the charger in without the battery on then tried to start it and unplugged it when it didn't work

after a while I put the battery back in again and tried the DL combo and it worked!

not sure what did it or why my phone was not turning on at all
[Galaxy S I9000 General] GoliathTheRipper:
I have a simple question....

Can I use a 3x 100k , 1x 1K resistors with 5% tolerance or I need to use a 1% tolerance????

Tolerance really matters ??
[Galaxy S I9000 General] gbohm:
yes it matters but you could try it because 5% doesn't mean it has to be 5% away of the desired value...

it still could be in the working range.

but if it's 5% away it will propably not work.
[Galaxy S I9000 General] xxgg:
Yes, this USB JIG will save it.
[Galaxy S I9000 General] Azzelio:
i try but not work:(
[Galaxy S I9000 General] xxgg:
Possible you have the right contact PINs ?

Well something must be wrong with the jig as I know personally you can recover from flashing ROM from different model.

TRY AGAIN
[Galaxy S I9000 General] Azzelio:
but in the first post TheBeano says that " If your phone screen is always black, that is it does not display the white Galaxy S/Samsung/AT&T logo when you switch it on, then sorry, this jig will not help you. "

see my pictures and tell me if everything is ok..

TRY AGAIN solder
[Galaxy S I9000 General] a_lan:
Anyone from UK would be interested in buying USB JIG. I'm asking because I will probably do it for myself but I need to buy at least 5 connectors and resistors. If anyone is interested send me a private message.
[Galaxy S I9000 General] muene:
worked very well for me:
[Galaxy S I9000 General] chandann:
One for me if reasonable!
[Galaxy S I9000 General] xxgg:
Your picture isn't clear enough for me to see what is goring on with the soldering points.

Can you take a picture with your camera with flash on, macro enabled and take pictures of both sides from directly above ?

Kind of like my pictures...

http://xdaforums.com/showpost.php?p=8952418&postcount=118

Look like red and black solder point is touch or something too... sorry can't really help with that picture.

Also, try this, as for the points it should be a point where BLACK wire is (which is a ground point) + 5th pin point which shouldn't have any wires.

So solder a resistor to the end of the black wire (so you don't need to solder directly to that tiny point on the usb pin). Than simply plug in to your phone and touch and hold the other end of the resistor to that 5th pin point mark.

If I remember correctly, you've said you used a variable meter or something... So I assume you had to solder a wire to it. From the pic it look like you are making contact with other points too.

Anyways, please retake the pic and let's start over.
[Galaxy S I9000 General] jta61373:
Major props!

Friends Vibrant was bricked, only screens were reboot recovery without a select option, and when in recovery when settings (soft) button hit it displayed "power mode or unknown upload mode". I used 3 100k 1/4 watt 5% tolerance and 1 1k 1/4 watt 5% tolerance resistors. Took a couple try's to get a good connection on the micro but once it did it fired up and went into download mode perfectly.

You guys rock. Much appreciated. I'll definitely be donatin

This worked like a flipping charm... and it was very simple!!! I've never soldered before but it couldn't have been easier once I had all the parts... I took apart and extra vibrant charing cable got a soldering iron and some rosin core solder with a pack of 100k ohn resistors from radio shack and I got it up and running and it cost me less than 20 bucks :) When I have some extra cash I will throw a couple dead presidents your way because you saved my life :)

Hey guys,

Need your help please.... First of all the JIG worked great since I flashed a Capative rom on my Galaxy S and had a Looping AT&T screen.

Now I can get into odin and have my pit file 512.

Just really confused about the .tar file ?

all the roms I have installed are .zip files... and my Nandroid Backup files are .img....

Like system.img

What do I do from here?

Im with Bell. Galaxy S
[Galaxy S I9000 General] MoWeb:
I'm not really sure what you mean by being confused about the .tar file but in ODIN you click the PDA button and browse to the .tar file. It goes there.

Hi can anyone tell me if this works on a UNBRICKED phone. I wanna use odin but i'm afraid that my galaxy bricks again (bricked once and sent to service they fixed it without any charge because i bricked the phone the night i bought it and told them it happened when i tried to update it with kies. :D ). So i have couple of friends too who has galaxy and stock with the carrier rom (me as well). If anyone try or post their experience (if already tried) it will be appreciated.
[Galaxy S I9000 General] alakaboo:
You saved me!

You XDA developers are really, truly amazing. I spent about 10 hours last night trying anything and everything to put my Vibrant into Download Mode. One of the block devices was messed up (see below) and I knew I needed to flash the stock firmware from Odin, but I could only access Recovery Mode. Even 'adb reboot download' (while in stock recovery) wouldn't do it.

I stopped by Radio Shack after work today to pick up some resistors and it took about 20 minutes of stripping wires and soldering (feebly, it's been quite a while since I've held an iron) to make the jig. I just about fell out of my chair when the phone came up in Download Mode. My girlfriend thought I was having a heart attack.

To anyone out there trying desperately to put their SGS into Download Mode and thinking to themselves, "There has to be a better way," this is the real deal, so don't waste as much time as I did. It has to be 301K ohms exactly -- I had 299K at first and it wouldn't work, so I had to add a few more resistors. I hacked this one together in a panic but I think I'm going to buy a breakout board (per the OP) to make a more permanent solution for future mishaps.

Thank you!

PS - Now that I'm up-and-running again, I applied the fix found in this thread to hopefully prevent me from getting locked out of Download Mode in the future. It works great using these instructions.

For future googlers with similar issues:

mount: mounting /dev/block/stl10 on /datadata failed: Invalid argument

E:Can't mount /dev/block/stl10 (Invalid argument)

E:copy_dbdata_media:Can't mount DBDATA:copy default media content failed.

A brief recap of what happened:

flashed T959UVJI6 over T959UVJI2 w/o .pit

rerooted

reapplied RyanZA's OCLF V1+ (ext2 lagfix w/ symlinks)

reenabled MobileAP using signed-mobileap.vibrant-T959UVJI6.v2.zip

rebooted into ClockworkMod Recovery

pressed apply sdcard/update.zip [not sure why I did this -- I think I thought it was required to reinstall CwM?!]

black screen after reboot, no Vibrant logo

used three-finger combo to bring up into Download Mode

flashed T959UVJI6 again, this time w/ .pit [my fatal error -- I should have flashed T959UVJFD w/ .pit]

now getting above errors, unable to get into Download Mode

panic at the disco
[Galaxy S I9000 General] othermark:
Yes. I've never bricked my phone, but built the jig "just in case," since I do not have 3 button recovery on this phone.

I made one and it works great fun project.

[Galaxy S I9000 General] SnoopyDog:
Hey, thaks for this hint! Unfortunately, the boot loader on my i9000 doesn't allow the 3 button start up to get the phone into download mode, but i'll test this one. I want to flash the new XXJPU firmware with Odin, cause everyone is telling that it's a difference like day and night compared to the official XXJPO.

As far as i understand, now i can put my phone to download mode and flash with Odin - great :D

Edit: pinballLooking: You CAN buy a 301 kOhm Resistor - why not? E.g. here: http://www.conrad.de/ce/de/product/421871/WID06W1301K/SHOP_AREA_17444
[Galaxy S I9000 General] triblood:
I've tried using the sparkfun board and used a 301ohm resistor, but it is not working for me :(. Is it because i soldered wrongly? I soldered 1 end to GND and the other to ID.
[Galaxy S I9000 General] MoWeb:
I used the same parts but when I soldered, I did that on both the top and bottom sides to make sure the solder flowed through the holes. Make sure of this. My jig is working ok.

This worked for mee too... Flashed my i9000 wednesday, something went wrong, did go pas boot animation but then only force closes and 3 butt wouldn't work..

I pulled out all resistors out of an adapter from an old phone and a digital cable receiver, untill I had a total of approx. 301 kOhm ( I had 301,2 kOhm ). I soldered these together, stripped the housing off of my usb cable, and I held the resistor against pin 4 and 5 ( I didn't want to f*ck up my usb cable so I didn't solder the resistor onto the usb plug.) . After 2 hours of trying finally I got the holy yellow triangle !!

Thnx for the solution !!
[Galaxy S I9000 General] TheBeano:
Is it actually 301 ohms, or 301k ohms? It has to be 301k ohms.

My bluetooth headset charger is my jig. I don't know if it's been mentioned in this thread but it seems that some chargers have right resistance built in.

JIG The Easy Way - No soldering required.

Disregard the above post, my bad for missing a page on the thread which has someone using the same type of connector as me (With detailed pictures).

Holding the resistors with your hands won't work, but if you duct tape the resistors and connect them (So your hands aren't touching any metal bits) you will get into download mode with no soldering required.

Cheers.

Will this only work with the charger from that bluetooth model or do you think it would be possible to get to download mode with the charger of another Jabra headset? I'm asking this because I saw some other Jabra headsets which I liked but wasn't sure if their charger would also work for dl mode.

Can someone with a different Jabra model charger comfirm this, thanks!
[Galaxy S I9000 General] dm-digital:
I don't know if other Jabra headset chargers would work or not. I would imagine they'd be similar but I can't say for sure. Since some chargers seem to have a resistor built in it must tell certain devices what is being connected to them.
