Download Mode with a hacked microUSB connector. - Vibrant General

Just felt it worthwhile to cross post this here. I am not the discoverer of this method, just an attentive reader of forums.
Should be stickied or placed in the Bible Thread...
This guide is for the situation where your phone is not booting and the three-button combo for getting into download mode is not working for some reason, and you have tried all the other solutions in the FAQ.
If the phone's bootloader is still intact, that is you see at least the white logo on the screen, you should be able to force it into download mode by connecting a homemade jig that simulates the Samsung "Anyway" field test jig. You can make this jig using a micro USB plug and a resistor.

Soft Bricked Help!

Trying to fix a friends Vibrant...
He was running jk6 software when the phone bricked itself in his pocket (?).
Now, the only thing we can do is access download mode by holding down the power button.
If I run Odin, and try to start up the phone into download mode, none of the COM Ports detect the phone, even though he is in download mode. Conventional methods don't work (Starting up ODIN, Plug in USB, hold down volume buttons). Only way I access download mode is by holding the power button down.
Any Help?
Try switching to a different USB port.

You need to make sure the computer has the usb drivers installed. Simple plug and play won't work. Its good you can get into download mode. Look in the bible sticky and download and install the usb drivers. Also if its windows vista or 7, when you open odin don't double click it. Right click and run as administrator. Also, make sure you open odin first before you connect the phone to the computer. Good luck.

Drivers have already been installed.
I can access download mode perfectly using my Vibrant and ODIN recognizes it, but when i plug my friends Vibrant in, thats when the problems happen.
For the record, when I plug my friends Vibrant into the USB port..a message pops up saying that one of the usb devices attached has malfunctioned (Code 43). I'm thinking this is directly related to ODIN not recognizing it (although it recognizes mine)
If you can reach download mode fear not its not an issue with the phone its definitely a problem with the drivers or maybe even try a different usb cable.
Yea, but I can only reach download mode. Phone will not boot into recovery, or even start up, just download mode lol. And i dont think its the USB, seeing as how i can plug in my other Vibrant and odin detects it immediately (on the same computer).

Well if the very same usb cable and port recognizes your phone (I'm assuming you both have the same exact phones) and odin recognizes your phone and not his, then his usb port on his phone must be where the problem lies... Try looking it, or even opening your phone and cleaning his usb port or something. Or try a different computer. if you can get into download mode don't worry, you'll find a way to fix your phone.
Still having the same problems. Tried a different USB cable, different computer running Odin...no luck. Only my computer detects that the phone even exists by shooting me an error saying that the device has malfunctioned. Phone just stays in download mode...Odin doesnt detect it. I've tried different methods to have ODIN detect it and still nothing.
Had to go through this too, but didn't have another phone in download mode to test against.
Win7 x64, tried a bunch of different drivers, but in the end was running the ones that come with Samsung Kies. In my case it ended up working without the original samsung cable (just a generic one), and with a USB port hanging right off my motherboard at the back of my tower. I have two USB ports on the front of my tower and they always errored, no matter what combinations I tried (including the same cable and driver). But when I switched to a port at the back, I got past the malfunctioning USB device error. Also, it seemed like Odin likes to be running when the phone boots into download mode. This took hours but phone runs perfectly now.

Trouble fixing up my Samsung SG-9006V hard bricked

Hello to everybody. I hope, you can understand me, because my english is terrible. I flashed the bootloader of my phone with a wrong image and I did a hard bricked, but my phone is not dead at all, so I have some hope to get it back. The first signal is that when I prees the power bottom a soft white bright appear on the left side of display, passed a second this light turn off and after turn up, and do this cyclically. The other sign is when I press the combination volume up+menu+power buttoms and appear a menu with three option, normal boot, recovery boot, fastboot, I must press volume down to ok, but when I press it dont work, dont work with any bottom I press. Well I saw in other post the sd card class 10 method to boot my phone but it didnt work. Today I dismantling it, I found 4 pins (RDX1, RDX2) (TXD1, TXD2). I assumed it was the serial port signal so, with a rs232 integrated circuit did something to connect to my pc with a usb-serial port cable, but it didnt work, odin and ADB not recognized my phone. Is there some software that work with DOS OS?. Somebody with more experience know something more?. I thinked to use a BOX software that they work with COM port but I dont know if it will work. Thank
Does Volume Down & Home & Power take you to download mode?
If yes, flash TWRP, and then the correct bootloader from TWRP recovery
Or just try flashing a full stock ROM with ODIN from download mode

Hard bricked is hardware bricked.
Soft bricked is software bricked.
You say you have signs of life so it's not the hardware......
If the download mode button combination doesn't work, buy a USB jig off eBay.....They cost pocket change....
Plugging it into the usb socket in your phone will force the phone into download mode.....even if it's powered off.
Then you can flash the correct software.

The micro usb socket 'form' (shape/design) is standard right across the Galaxy range....I've used a Galaxy W, a Galaxy S2, a Galaxy S4, a Galaxy S5 and a Note 4......They all use the same usb socket.....
The difference between usb 2 and 3 is purely data transfer speed......
In all other respects, usb 3 is backwards compatible with usb 2.......
The jig WILL work......If anything does....

What do you mean it didn't work?
I know ebay deliver fairly quickly, but last time I checked, they weren't offering a same day delivery service....so unless you already had one, there is no way on earth you could have tried it....

Apologies, but I I thought you didnt read the post carefully, I thought you read very quickly. But I think my english is very bad, sorry for that it wasnt my intention to offend.
I didnt buy the jig I did it. It´s easy to do, I saw information in the net. It comes a resistance of 300Kohm between pin 4 and 5. I had in my home the plug and the resistances

(ok here a update im making progress so i started from the jump went through a box of old micro usb cables found 2 cables that seem to work better than others 1 seems to trigger more often than other but its not a everytime i plug with button combo it pops unrec usb but when it dose sometimes it continues to do it then stops i also found a 3in1 OTG moblie phone connection and when i us it (first just plugging in the OTG to pc it pop unrec device and shows up in
usb controllers) (second when i connect the phone with different button combos the pc detects as unrec usb device but non of the mtk or lenovo nor qualcomm drivers rec the phone i tried to assign the drivers lenovo for it but its there not the rite drivers and the proper ones are installed for the device? "now it did let me assigned and give me the options for some qualcomm usb drivers but the only i rec was a 9006 {it didnt offer the 9008} but after installing it showed with error but still did not rec the phone. so now im not as bad off as i was per say. im going to look into this OTG thing as it really helps pc see the phone as a unrec usb device but no matter which one i use rite now i need to get it to or for the drivers to see the phone.
i still having trouble getting my laptop to asign a driver im getting unrec usb but unable to asign lenovo usb drivers or qaulcomm dirver it tells me there no drivers for it and check to see if the 64bit so my win10 dose not rec those drivers for 64 bit so now im in driver issue now

Bricked Galaxy S8 USB JIG?

Hello! Long story short I've tried to flash TWRP from Linux with a Windows VM using ODIN and ended up with a "hard-soft" bricked phone. Hard-soft because on the phone is just a brick with a fancy screen that displays only the logo. No recovery, no download mode, no $lsusb recognition by the PC. I'm hoping to be able to boot in download mode using a diy USB JIG that I am willing to create. Only small problem: I can't find any schematic or any guidance for the type-C connector. Does anybody know if the JIG method is still present, if so, where should I connect the resistor to? Also, if you have any suggestions on how I can bring my phone back, I would appreciate the help. Symptoms are as followed: The phone turns on, displays the Samsung logo and from there is an infinite bootloop. The key combos for recovery and download mode are not working. Can't even force reboot the phone. At this point I have opened up the device and removed the battery connector, reconnected the battery after ~12h and still the same problem. Also, there is no charging interface when I plug the phone into the charger. Now it's just a fancy brick. PS: It's the exynos version. Thank you!
EDIT: The volume rocker wasn't working. After securing the motherboard better the I was able to recover from download mode.

Semi-bricked S8 Active can't get to Download Mode - any usbjig for USB-C?

( Not sure where to post this question, and a search didn't provide any answers, sorry if it's been answered somewhere here... )
Is there a usbjig for USB-C? I have a Samsung S8 Active SM-G892A that's kinda-bricked. An ODIN flash failed and the phone now shows a blue screen with message "An error has occurred while updating the device software". The usual button sequence to get into Download Mode works as far as the warning screen, but Volume Up takes it right to the above message. And the phone can't be turned off, so the battery is discharged. When I plug it into the charger, I get the above message. I have tried all the usual key press sequences.
ODIN can't connect to the USB. But interestingly, FRP Hijacker could (but didn't help), so the USB is alive for comms. Don't know why ODIN couldn't talk to it. I also tried Smart Switch PC, same problem. Reinstalling the Samsung USB drivers doesn't help.
I'd try a usbjig to get into download mode, but can only find micro-USB versions and the phone has USB-C. Do USB-C phones not respond to the usbjig method? If they do, where can I get one? Or how to make one? Can anyone here help? The phone makes a lousy paperweight.
Please and thank you.
Can anyone help with this? USBJIG for USB-C? Do adapters work for entering download mode on USB-C phones? Thank you.
