How to DIY a Download Mode Jig dongle
If you ever have a problem or getting trouble how to set the the Samsung Galaxy S and other Galaxy S I900 or Galaxy S II I9100 and other series into 'Download Mode' if pressing the three button combination (Volume down+Power+OK) failed or not working for some reasons while flashing the phone using 2nas Android Flash Tools. This solution may help solved your problem.
All you need is a good soldering skills, a little bit effort and creativity and some components and tools below.
* micro USB cable
* a 300K and 1K = 301K 1/4 watts Resistors (A 300K will work also)
* Soldering iron at least 20Watts and a soldering lead
* a cutter or knife
Here's the block diagram to DIY Download Mode Jig dongle.
Procedures:
All you need is to solder the pin 4 (ID) and pin 5 (Ground) pins of the micro USB plug. Just cut out the sleeves of the USB plug, then attached and solder the 300K resistor across to pin 4 and 5. Just as like this finished product below:
How to use on Samsung Galaxy S while using 2nas Android Flash Tools.
1. Pull out the battery for about 2-5 minutes, then inplace it back again. Do not turn it ON yet.
2. Connect the jig you just made. Avoid touching the resistor and pins on the back or just put a a non inductive cover around it, an electrical tape works. The device will just turn into download mode in just a couple of seconds without pressing any buttons.
3. Once the Samsung Galaxy S displays the Downloading, disconnect the homemade jig USB plug and connect a regular USB cable from your PC to the phone, then you can flash the device using 2nas Android Flash Tools.
Or to avoid any hassles or without any soldering skills ask Google where to find it.
It's very cheap to have it, but this USB Jig dongle will help you access to download mode even if your phone is 3-button combo disabled. If u plan on getting root access or adding ROM'S, you should have a dongle jig on hand just in case things do not go as planned. Download Mode Micro USB Jig will allow you to access the download mode on your Samsung Galaxy S Phone again.
This JIG also work with other phones below:
Samsung i896 Galaxy S Captivate Samsung T959 Vibrant Galaxy S Samsung Galaxy S Epic Samsung Omnia 7 Samsung i9000 Galaxy SSamsung Galaxy S Fascinate Samsung I897 Galaxy S Captivate. Others not tried yet but it might also.

Hi everyone
Is there a program that makes my pc usb to act like a jig for samsung galaxy S and force it on Download mode
Why not I mean?!!! while we can control the all of the usb ports
Be more clear. What exactly u want?
Sent from my HTC HD2 using xda premium
No, because the USB jig itself is soldered a certain way (the pins, internally).
as said, one of the pins that is joined with the resistor is not connected to any wires...so its impossible.. they are only £2 on ebay or make one
Hi all.
I heard that zte blade has the capability of USB HOST. Also heard it can't power the usb slave device attached to it. Instead of purchasing a usb power hub, i manually tried making a cable which has the similar function but draws power from PC usb port (don't know how far it works. I haven't been successful).
The description of the cable i made is in the picture attached below.
PLEASE SEE THE PICTURE ATTACHED.
For a device with native usb host (such as galaxy note) i guess the device USB-CABLE coupled with USB-FEMALE-TO-FEMALE-BRIDGE is enough to attach slave devices. But for the devices which cannot give power supply in USB HOST mode i assumed and tried the cable which was described in the picture.
Blade was my handset. My friend had galaxy note. I tried connecting blade as a slave to galaxy note with a NATIVE USB-OTG CABLE. But it said the slave device is high powered and needs seperate power supply. In such case i think the cable i prepared might work (if it works) replacing usb powered hub.
Ok, coming to our zte blade device. I prepared a usb female to female bridge and connected it to usb plug of usb cable. Then i connected only the data + and data - of USB PERIPHERAL DEVICE to zte blade. The VCC +5V (red) and GND (black) are supplied from a PC usb port.
And im sure i connected data+ to data+ only. And similarly (data- to data- only) , (vcc to vcc only) , (GND to GND only).
And i tested it with a usb keyboard and a memory card reader. I tested on cm7.1.0 because i heard this build has kernel supporting usb host (? Is it not?). Im unsuccessful with both tests. When i connected memory card reader the led light in the card reader turned on but i cant see any drive/folder/notification on m phone. And with usb keyboard there is not even NUM LOCK led on. Am i missing the kernel support or something. If so pls tell me what kernel should i use.
And is it the thing i prepared wont work at all.??
Please give me suggestions... Thanks.

Hello everyone.
I am currently modding Samsung Galaxy Tab 2 7.0 for car instalation and everything seems to be great except I have problems with two things:
1) As the tab will be also my main music player I would need an USB host from time to time (check: http://www.expansys.si/samsung-usb-adapter-for-galaxy-tab-series-no-30-pin-to-sd-slot-229630/ ). It would be hard to switch that adapter with power supply just for the time I need to stick USB in it so I am asking if anyone knows if it is possible to have both active at the same time: power supply and USB host? Or if anyone has some other interesting idea how to transfer data to tablet asap from time to time? Please note that it will be really hard to reach it when installed.
2) Since the tab has back camera (which is useless to me in cars interior) i was thinking if there is any possible way to get that camera out of the tab with some extender or something? I've been looking at the interior of a tablet and the camera doesnt look to be attach in any other way than just a flat cable. Any ideas?
Thank you guys for your help in advance!
Make love, not war <3

It sound like this will be a permanent installation.
Instead of €22 for an adapter, I'd rather use a breakout and hardwire:
http://www.kineteka.com/galaxy-tab-connector.aspx
This will also allow you to wire the earphone output also.
Yes, with many devices you can charge and do host mode at the same time.
It's mostly a question of convincing your device to play nicely with a non-standard operation.
You can just bring out the USB leads or hardwire in a hub for more options, like a keyboard.
I'd use a DC converter circuit board hardwired instead of a cigarette lighter adaptor.
Something like this, maybe: http://www.lightobject.com/LM2576-High-Input-7V40V-Switching-5V-Power-Module-Regulator-P549.aspx
I think somewhere in the Tab 10.1 forums, someone figured out the proper wiring for a powered USB host adapter. 90% certain that would also work on Tab 2 7.0
i try to connect a usb flash memory to my tab 2 and i follow a trick
i get female-to-female usb adapter and connected it to the galaxy tab 2 usb adapter (that comes with it in the box)
then connect to it a usb flash memory , but my tab didn't read any thing
so after searching,using my avometer and making tests between my tab and my lab i concluded that:
-the female-to-female usb adapter is working probably
-there is no 5v output on the usb male adapter so i think because that the terminal device can't be read
please help me, any one can explain that?
is the manufacture close that property or my android is crushed or must be a microcontroller in otg to work,.... or what??
hey ever body , where is the developers
where is the genius people
i need help
My guess is they sell an official USB reader for a reason...

:silly:
The following link shows how to make your own OTG cable (for another device). http://tech2.in.com/how-to/accessor...sb-otg-cable-for-an-android-smartphone/319982. So there is some additional connection b/w pin 4 & 5 that makes it works as OTG cable.
Is it worth the hassle? I am not sure. I got OTG cable for $0.99 in ebay. Before buying it I tried female USB cable like OP and failed.
thanks for every one tries to help
i found the reason
the secret in the 30 pin connector
which its pins are grouped each group is serves another connector in the another side of cable
so the group of usb has a pin named otg responsible for turning your cable to otg cable
so in the usb male connector it is not connected
so i think that is why samsung didn't built in its tabs a micro usb port and built this port instead it "to can market its accessories"
i recently bought a samsung s4, and i realized that the end port of my microusb cable (the microusb end) only have 4 copper pins instead of the usual 5. Is this a product problem or did samsung designed it to be 4. The usb charges the phone with no problem but im just wondering if it is causing an issues.
p.s: it is the 3rd copper pin thats missing
