But YOU will NEED these:
And
Those two items is all you need to make this work, no soldering iron.
Now the reason I purchased the iGo adapter is cause of this guy here: As you can see, there is 6 pins on this thing.
Micro-USB has 5 pin connections. On a hunch, I was hoping all 5 pins were some how connected to the to the 6 pin adapter, so we didn't have to try and solder the resistor to pin 4, usually hidden in most setups.
Now the most difficult part of this whole process, was trying to get the micro-usb apart, which wasn't that hard at all.
Just take your time. I used a razor, scissors, and my teeth, lol. This is one part I didn't take pics, sorry. But try and "skin" (sort of like peeling) the black piece off.
Once that is off, you'll see a white plastic piece also around it, "skin" that one off too.
Once the white plastic piece is off.
The micro-usb connector and the 6 pin board is held together with a silicone compound that is bonded to the wires.
SLOWLY start picking the silicone compound away. It's really not that hard, just takes time.
Once that is done you should have some thing like this:
Now take your resistors and connect them in series: These are again, 100k resistor x 3. Should look like:
Now let's take a close up of the micro-usb connector. I don't know exactly which is which but I do know that both are pin 4 and 5!
Look at how long they are...that's what makes them special. Pin 4 is not hidden!
Since you got this far now just stick that bad boy in (please make sure the phone is turned off).
I should of cleaned up the wires but I was sort of in a rush:
VERY IMPORTANT: Don't let the other wires touch the connectors to the usb!
That image is with the screen facing me.
Now put in your battery, and take your resistors that you made and connect one end to pin 4 and the other to pin 5, not necessarily in that order.
Make sure you hold the resistors to the pin for at least 3 sec.
Viola!!! DOWNLOAD MODE!!
This was a quick fix for a jig that I needed to get MY phone working without soldering iron, and it worked. The hardest thing so far that I read about making a jig is getting to pin 4 that is usually not being used and hidden. At least this way it's easier to access.
I will end up buying another one and re-making my iGo jig to a more sturdier standard.
By all means, I am not a expertise in this field. I just been reading alot of threads and learn as I go.
So I am sure anyone can make this jig to revive their bricked phone. Trust me, if I can make it, so can you.
*edit: But if you have the chance, please pick up the 1k resistor also (not shown).
100k x3 and 1k resistor, this is the exact recommended ohms to make this work. 301k > It's the right way.
*I do recommend for those that have successfully done this, to (learn) solder the end pieces together. Pin 4 and 5 are long enough so it shouldn't really be that hard.
You won't have the tedious task of trying to manually connecting the two ends every time you want to go into download mode.
Plus I believe basic soldering skill is a must if you like tweaking or a hobbyist of electronic components.*
All the images were take after I was able to get it in download mode. Was not really thinking about doing this write-up, until after the last picture.
Hoping it may help the community one way or the other, and save some $$$
although a sloppy first attempt....this is GREAT knowing that there is an option out there. Thanks for doing the dirty work and purposely bricking your phone to help everyone else. Takes more guts than i have
Great thread. Thanks for doing this kind of thing for the community. I already felt comfortable that Odin could save me a lot of trouble, but now I feel like I can go completely nuts and not half to worry.
So I thought you had to get into Download mode WHILE the phone is plugged into your computer and ODIN is running.
If I understand right, you can use this jig to get into download mode, unplug the jig, and then hook up your phone to a computer and run ODIN?

Yes, you are correct. When using the jig, your phone will not be connected to anything, except the jig itself. But before using it, you should take out your battery, SIM, and SD (if you have one).
Plug the jig in > put in the battery > connect with resistor for 2 to 3 sec.
Once the screen is in "Download Mode" > pull jig > open Odin3 on computer > plug in usb to phone > then run Odin3 > done.

Yes I do advise to get it cheaper if you can.
But this is what I had to do to get it up and running that same night, just wasn't that important to me to save $10 for something that will get to me in a week. And I'm sure if you were in the same situation, you would of done the same thing to get your phone up and running.
But THANKS! I needed that link.
9.3% SALES TAX!!! FFFUUUUU that sucks.
9.3% isn't bad.. it's 9.75% here :T ..
and to sum up this article!
you don't really need to solder anything as long as you just rip the usb apart so the wires don't touch when you make your jig!
pretty legit mod, imma try and clean this up a bit and see if i can do a better looking job (no offense on ur job though!)
Another "How To"
What the.. duplicated post... weird.
Another "How To"
Alright guys, I bricked my phone last week (well, not bricked but disabled my 3 button combos and it was FCing on OS boot), and so I set out on the forums to find a clean-solderless alternative to getting into download mode. I didn't feel like dissecting a microusb cable, nor did I feel like soldering
This mod requires:
About a week wait time
A backup phone (if yours is already bricked so you have a phone to use)
A XDA and a Paypal account
First I found this thread (http://forum.xda-developers.com/showthread.php?t=819551) and went over to (http://www.sparkfun.com/commerce/product_info.php?products_id=10031) to buy a micro usb breakboard. It cost me about 9 dollars shipped to my door. I ordered it on Tuesday, and it got here on Monday (Thursday was veterans day, too). Came in a nice box in which I now store my completed jig.
Edit: Well the person I got my resistor from isnt selling them anymore, so you'll need to find someone to get it from =/ sorry! this isnt as useful then D:
Then you just plug in the resistor in slots 4 and 5 like so...
And you have a working jig. Really easy, works perfectly, and no cutting into any microusb cable. And now you also have this nice little box from sparkfun to store your jig in too. Don't forget to not touch the resistor when you insert it in your phone. Just hold it by the edges of the breakboard. This cost about the same as OP but just requires a little more waiting time. But it's so much neater and less troublesome.
Good Luck!

post 198, if you want to pay someone to make a JIG for you go here.
I have a bunch of parts for JIGs being delivered to me on Monday. After I make mine, I'm willing to sell the rest to people who need em.
wow that sparkfun jig is REALLY cool!! I don't understand why everyone is so scared of soldering though, unless they simply just don't have a solder gun (you should have one anyway).
I think i will order that sparkfun breakout and solder a resistor in for a nice complete jig.

the reason i didnt solder is because im away at college and all my tinkering equipment is at home (which is about an hour and a half away). i didnt want to buy new equipment just to fix my phone, nor did i want to wait til i went home again..
soldering is easy but it can be daunting if you've never done it before. i mean i've burned my self on my iron before and it was not a fun ordeal ahaha. otherwise from that, this worked quite nicely so i dont need to solder--saved me money and time
they are showing that board out of stock...you must have got the last one!
Since this thread was one of the ones that inspired me to make a Download mode jig, I thought I'd share what I put together today.
Made with a MicroUSB female plug, 300kohm resistor, & wire from a torn apart ethernet cable. I had originally planed for it to be half the size of what it is, and a lot cleaner (without a loop in it). But soldering to the damn usb plug was a pain, and the tins are fairly fragile.
It works like a charm though!

Looks great and clean work! I ended up purchasing 2 of the micro-usb break-out board, yet I still use the one that is posted to get me into download mode.
I don't know if it has any affect or not, but when I flash to stock with Odin.
I normally won't do a "adb reboot download". But I will turn the phone completely off, pull battery for 5min, then use the jig to get it into download mode, then restore.

so I bought the dock for the mytouch 4g, and have to say it is pretty good, for the price though they should have included power cables... The design of the dock is good, and if they took out the mini usb plug and just did the 3-pins, the dock would still stay in place.. dunno why they didnt do it ??
well, two days after I bought the dock, I modded it so that every time I would dock it, the dock app would activate will post up vid and pics

I opened the dock up and checked the wires, I read on a different post about the nexus dock and how it activates the dock mode on the nexus 1.. well the green wire is what activates the dock mode , and I checked the wires on the mytouch dock and it has a green wire, so I hooked up the usb plug, and ran a wire to the green wire to see if it would do the same as the nexus dock and to my surprise it works...
nothing to special, but I might do away with the usb plug and put 3-pins, did this just to see if it would work...

Man, that's pretty hardcore. Let us know how it turns out.
Yeah it is, but I was tired of fighting the phone with the usb to get it to sit right.... Even with the usb plug out the phone stays in place when its vertical!! Its pretty snug fitting!!

One of the problems with the Nexus dock that has those three buttons is that you cannot sync with it. It only powers the phone. I have two of them and the only issue I have is its difficult to seat the phone in the dock. Let us know if the dock will sync with those three buttons.
Wow, your mod makes me all the more frustrated that this official dock uses USB. If you pull this off, I think you could have a nice little mod business on the side. Consider me an interested party.
I thought about modifying the dock so that it's easier to seat the phone, but you're going the distance! So cool.
I still can't believe they released this phone with charging pins, and haven't released a single accessory to use them.
thats correct, the three pins are only for power, ground and home/car dock app activation.. I know that the green wire and the yellow wire are data +/-.. with the design of the dock, the dock hugs the phone perfectly and the pins sync perfectly, I just lost one of the smaller pins so I didnt get to solder it to the green wire but it charges...

Thanks Jon C, the thing is hard to open because it is superglued on. I mean its not that hard, but trying to open it without damaging the glossiness of it is pretty hard lol!!
I would do it, but not alot of people would buy the dock for that price!! it kinda hard to get the pins perfect but I got it to work....
exactly what I was thinking, why have the three pins when you don't use it or have anything that uses it...
I was thinking of modding the powerskin that they released for this phone, but dunno if I wanna spend 70-80 on it..

here is an updated video...
Ok.. where did you get the charging pins from? I'd like to try this mod myself because, as far as I'm concerned, the dock as it sits now is useless. It's only a matter of time before its use breaks the USB connector from the pcb in the phone.
Thanks!
Got the pins from allied electronics... Look for battery pins..
But its at your own risk if anything goes wrong..
I say the hardest thing is to get the holes to line up correctly when you drill...
Also, the green or yellow wire works to acrivate the dock app..

I completely agree! I'm ****ing pissed about the dock. It doesn't even do audio through a hard connection. Very disappointed and planning to return it.
Hmm what do you mean it doesn't do audio?! It has a 3.5mm audio jack with bluetooth audio....

Edited my earlier post, sorry.
It's a DOCK, it should have a hard connection for audio and automatically trigger dock mode through pins not usb. Very big letdown...
ahh ok, I thought you had a audio problem...
The dock holds the phone in its place even without the usb plug..
well I finished my dock modd!! will post a vid...
FYI: the pins are: looking at the pins while the phone is layed down;
left - (+)
middle - (-) triggers desk mode/car mode (negative, triggers desk mode)
right - (-)

mehhh here it is..
I have discovered a cheaper and less destructive way to unbrick the totally bricked captivate using only 3 resistors, THAT IS IT! No need to cut up your USB cord, JUST 3 resistors.
Below are the steps and pics:
YOUTUBE INSTRUCTIONAL VIDEO
1. Go to your local Radio Shack and purchase a pack of 100k ohm resistors, the colors should read Brown/Black/yellow/gold (see pic 1)
2. Take 2 of the resistors and twist them together
3. Take the third resistor and twist it onto the other 2 to make a straight line of 3 resistors
4. Bend the 3 resistors into a teardrop shape (see pic 2)
5. Set down a piece of tape and place the tips as close together as possible without touching while leaving about a quarter inch of each tip exposed, this will take some patience and adjusting (see pic 3) *tip: try putting a piece of tape or two in between the tips so that they do not touch each other*
6. Once the tips are set correctly tape both sides of the tear drop so no metal is left exposed. If your skin touches the metal it reduces the resistance of the jig and will not work.
7. Remove external sd, sim card and battery. Then replace battery and DO NOT touch the power button.
8. Carefully touch the two tips of the jig to the two copper plates of the micro usb slot closest to the headphone jack for about 3 seconds (this will also take some time and patience) *tip: use the other side of the micro usb port to brace against to hold the jig in place*
9. The phone should now go directly into download mode
9a. If your phone build number is BELOW 1010 continue following this guide.
9b. If your phone build number is 1010 or ABOVE follow this guide to flash back to stock.
10. Open odin3 on your computer
11. Plug usb into your phone, after odin says "added" click start to flash the stock rom.
12. Profit!
This fix as opposed to the others only costs $.99 and uses ONLY 3 resistors, NO CUTTING OR SOLDERING. Other fixes suggest hacking up your micro USB cable to use as a connection but i found that to be unnecessary.
As snapplefish has pointed out the desired resistance for this to work is 301K ohms, not 300K. HOWEVER, I and almost everyone else here has been able to only use the 3-100K ohm resistors. IF you are having trouble getting this to work, AND you have made sure you are using 100K ohm resistors, try measuring the resistance of your jig by using a multimeter. IF your resistance is below 298 or so try adding a 1K ohm resistor to your jig and remeasure the resistance of your jig.
Thanks to everyone who came up with the 301k ohm resistor method, saved me from a $500 paperwieght!
If this has helped you please give me a thanks
Cheers and happy flashing,
Alex

Brilliant! Hopefully I never need to use it. This should go as/with/in a sticky.
I hope I don't ever need to use a jig but this is a great alternative to other methods. You do need to have the USB plugged in prior to touching the resistors correct since that is not stated? Common sense says yes but I figured I would be the idiot to ask haha
Well he's actually fishing around inside the phone's MicroUSB port to touch pins 4&5. So no, in this case...you don't need to have a USB cable plugged in.
But with other JIGs including mine, you plug the JIG into the phone.
Trying this tonight. Will update.

I have never been able to have Odin work without it being open and having the USB plugged in when getting to download mode. How will this work if you get download mode prior to the USB being plugged in for Odin to recognize?
This is my captivate. There are many like it but this one is mine.
I frequently use my JIG to get into Download mode to flash with Odin. For me, plug a JIG in to force Download Mode. Remove JIG, connect phone to a computer running Odin. The phone should be "added" in Odin and you should be able to flash away. I actually just did this last night as well.

True story. This guy makes good JIGs. I was very impressed with it. Tested it a few times and threw it back in the Samsung box.
I phone--/triangle\--PC bricked my first Captivate. Odin 2.1 got stuck on "Setting PIT" and I was able to return it (had it a week and claimed it did it on an OTA update lol). I had the 3 button download disabled (probably a 1008-1010, I have a 1010 now) and couldn't get into download mode so I could've saved the first phone but no one was building JIGs yet
Anyhow, I don't *NEED* it, but I'm GLAD I have it. I'd probably not flash without one.

For this to work, you need to have ~300kohm of resistance across pins 4 and 5 for at least 4 seconds. You cant touch bare metal on the resistors, or you'll change the overall resistance.
Yes, this is a cheaper implementation of a JIG, but it's also a little harder to use compared to if you were to just cut up a MicroUSB plug.

This isn't going to work for me. No metal has been touched, using exact resistors as described and touched pins 4+5 together. Oh well, new device should be here in 2 days.

You are correct, this is cheaper and I figured it would take me about a half an hour to cut up the usb and another 3 to 5 days to recieve another one through amazon so this was a quicker way and maybe a tad harder.
This took me a total of 5 mins on the ****ter to make and 15-20 mins of adjusting and trying until I was able to get it to work. This seems like the quickest overall and easiest way to make a download jig, but if you have more money then time just buy a pre-made jig.

Make sure each tip is only touching ONE pin. They should not touch together or it will short circuit and not work. In my jig there is a small maybe 1mm or less gap in between each tip.
After messing with the spacing I was able to consistently put my phone into download mode. I also put some tape between the prongs to ensure they didn't touch.

Glad to hear it!
I also put some tape in between the two tips but wasn't sure if it did anything.
I always do it just never would work when I wouldn't have the usb plugged in at the same time of download mode. But if it ever becomes the case I will surely give the jig a try. Thanks for the info.
Updated first post with a youtube video of myself performing the unbricking procedure.
Hello,
I know there are a lot of threads on this topic but I tried to use what I learned on this forum to get out of my own jam with local parts.
Disclaimer - I am not responsible for you doing further damage to your phone.
History -
Tried to restore captivate to stock, got phone in download mode - started Odin... looked like things were not starting correctly... pulled usb and battery out... and BOOM.
I got the dreaded phone=computer type display and could not get out of no matter what buttons/battery hold down combo I tried. Note this phone did not support the 3 button trick- it was a 10.07 version.
So -
Go to your local Radio Shack and get part numbers 271-1347 (100k ohm) and 271-1321 (1K ohm) resistors.
Also you need a solder iron and some solder...buy that if you dont have any.
(a meter is nice to have too... but not entirely necessary)
Take your USB cable apart. I had 2 styles of ebay cables... I used the one with bigger shield/jacket. Just look at it, it pops apart at the seams.
Then you see the where the cable is soldered to the micro usb jack.
Before this step... I cut the cable in half and was planning to use the wires for connection points .. not the jack itself but that did not work.
In this cable there are 4 wires...but on the jack there is 5 pins.... and of COURSE pin #4 is the one I need but it has no wire attached to it. ( I found this all out after using my meter on this assembly for a few head scratching minutes...also...if you twist a stripped bread tie to your meter lead it helps in ohming out the pins...)
So - back to the solution
Pin #5 has/had the black wire on it and #4 has NO wire attached on the micro jack.
To clarify - if you are looking at the jack with the pins showing - pins and connections to #4 and #5 are on the right end of the jack - one on the top and one on the bottom of the jack...hope that is clear... if not the pics should make more sense.
Now that you know where the #4 and #5 pins are on the jack, go get the Radio Shack resistors and turn on your solder iron.
Take 3 - 100K resistors and 1 - 1k resistor... Twist the resistors together in series...and solder the joints... then trim the ends up....see the picks.
Take the now cobbled together 301K ohm resistor and solder one end to pin #5 and the other to pin #4. (note you will have to unsolder the black wire from #5 BEFORE you can solder the resistor to it...assuming your jack/cable is like mine..)
Now -
With no sim, memory card, or battery plug installed, plug in this cobbled up mess into your phone.....then put in the battery....
If you did it right it... the phone will go into download mode in seconds.
Pull out the mess and put in your good cable (or put yours back together) and use ODIN as usual.
This saved my butt.
Hope this post might work for someone else some day.
Thanks for all who posted here showing me what is needed to make this work.

thanks Kevin
Thanks for the great write-up. What is the reasoning behind what makes this device work? What is it about the device that makes the phone go into download mode? Just curious.

the phone was designed that way...
Wow, looks like an elaborate setup..glad it worked for you! I think I'll pick up a premade jig though hehe..I have no experience with that sort of tinkering.

Because the phone was designed that way... Certain resistances on usb port will trigger the phone to do different things. 301 is download mode there is one for car dock and others i would imagine

I've been enjoying mobiletechvideos video reviews of the roms and instructions on how to do stuff, so I ordered a $10 jig as a combination donation/insurance policy. If you enjoy the video reports, throw Josh a bone and grab a USB 301 ohm jig.
I suspect it's easier to store than the resistor model.
Although I'm sure if I was in the OP's shoes, I wouldn't have waited for delivery either. Interesting about the only pin that doesn't have a connection is the one that you need to put the resistor across. I suspect that was completely by design.
I was able to use three 100k-ohm (300ohm) 1/2 watt resistors (radio shack #271-1131). And because I didn't have a extra cord to hack up I just taped up the resistors and was able to touch the two points and get it to work
This forum is a great resource for good information.

That is exactly why I went down this road -
I had to get this fixed quickly and not wait for something to come in the mail... or maybe come in the mail.
I also saw Josh's video and promptly ordered a jig from Josh on 2/24 I also sent a follow up email to Josh a few days later.
So far I have heard nothing from him and have not seen the jig in the mail.
EDIT - Received the jig from Josh today 3/2.
Sometimes you have to take matters in your own hands, so speak and I got my phone up and working in 24 hours... if I had the time to run to Radio Shack that night it bricked, could have been resolved in a couple hours.
thanks/good luck to all

I am looking for a dock that can charge the phone, a spare battery, and pass through audio. I have come up with this one: http://www.newegg.com/Product/Product.aspx?Item=9SIA1PU0SD7919 Does anyone have any experience with this unit? If not, I think I might just jump on it as I saw few other options. You guys know of any other dock that would work well for me at this price range?
I'd get one at that price, if I was in the USA

Looks good kist but that one doesn't have an audio port. I connect my phone to my desktop speakers at work and don't want to constantly have to plug and unplug the audio cable into the phone.
I've done a lot of desktop cradle browsing, and I haven't seen one that does both. One or the other, but not both.

Well I found 2 or so including the one I originally asked about. I think I might just bite the bullet and order it. Newegg will have my back if it sucks.
If you do, please let us know how it is. I'm amazed that such things are so difficult to find.

I have this, it works fine. It says the light is supposed to turn green when the battery in the rear has charged. But it doesn't unless you take it out and put it back in again. I'm not sure if it overcharges the battery or not. The battery does not get warm or anything, so I assume it switches off.

Once again thanks, but it doesn't have the pass through audio option (which is very important to me). I ended up grabbing http://www.amazon.com/VicTsing-Desktop-Charging-Detachable-Function/dp/B00CMNRLRS/ref=pd_ybh_7 and I will let you all know how it is when I get it Friday.

Sharp, you have the same dock as I received. I can tell from the look of it and the instruction book. Please see my issues below and let me know if you have the same problem.

I ended up buying the dock from an Amazon seller. It is the same exact dock as I originally posted. I am having an issue with the dock right now and am working with the company. I will update you when I have more info.
Some initial impressions:
I am using the dock without a case on the phone. There is a spacer on the dock you can remove so I think most thin cases shouldn't have an issue fitting. When just the power is connected the phone does NOT go into dock mode (if this is important to you). I have it connected to a wall outlet and not by USB to a computer so I don't know if that makes a difference. I will test it out tomorrow. However, this might be solved by plugging an audio connector into the dock as explained below. I think there are also apps which can force dock mode when connected to power anyway. However, the dock DOES charge both the phone and spare battery without issue. The phone is pretty stable in the dock and I can text while the phone is in the dock without knocking it over (as long as I am gentle with it). I would like a little more bottom weight to the unit but it is acceptable. Inserting and taking the phone out of the dock is currently a 2 hand operation. I will try to see if I can come up with a way to do it with one hand but the phone locks into the dock pretty tight. It is difficult to get the spare battery into the slot. There is a little tab in there that pushes in when you put the battery in. I don't know what the purpose is as the slot is pretty tight fit as it is. If you try to push the battery straight down it will not go in. You have to angle it in from the charging side which pushes the tab in and then push down and it will go in. Once you figure out this method it is easy to do.
Now on to the problem. When I took the dock to my office, where I will mainly be using it, I connected both the audio cable and the power cable to the dock and slid my phone in and I got nothing. No charging, no audio, nothing. I checked all the connections pulled them in and out as well as the phone but I still go nothing. I tried just the power and it worked fine as stated above. As soon as I plug the audio cable in the dock stopped charging. I tried just the audio and that worked fine without issue and the phone DID go into dock mode when the audio cable was connected. It played audio fine through my speakers and all was well. However, when I plugged the power cable back into the dock .... you guessed it... audio stopped playing and no charging.
I take it I received a defective unit. It IS a cheap piece of crap from China so it is bound to happen. Perhaps I am having an issue because I am connected to a wall outlet instead of a computer? The company is very willing to work with me and are quick to reply to email. From their first response they seemed puzzled at this operation so I assume that this isn't normal operating procedure. I assume they will send me a new unit and when it arrives I will let you know how it goes. If the new one functions with both the audio and power plugged in I would absolutely recommend this dock.

thanks for your review! hopefully the new unit will function properly.
So here is another update. When I got back in the office today I tried plugging the dock into the USB port instead of the outlet and both power and audio worked without issue. I then tried another wall charger and had the problem again where neither of the ports would work. It was the same brand charger as the first so I tried another and the same problem. I tried a third charger and that one finally worked with both ports and things were dandy.
However, I realized some time later that there was serious static interference sound that I couldn't get to go away unless I unplugged the power. I tried a different outlet, different set of speakers, different chargers, different usb cables, wall vs usb, different outlet and the interference is still there. If I have the volume on the speaker low and the volume on the phone at the highest the interference is almost inaudible (I have very good ears so I still hear it) while the music is still a good volume. However, if the phone audio is lower and the speaker volume higher it is VERY audible. As soon as the music stops or the power plug is pulled the interference goes away. It seems as if something is not properly shielded inside the dock. I followed up with the vendor and will let you guys know what they say.
so , i have a G6 i was using a samsung aftermarket fast charger QC3.0 , just when plugged it in the phone vibrated couple times (like of plugging and unplugging the cable) then turned off completely , and won’t turn on tried hard reset .. etc
when i plugged it to the car 12v charger the light of the 12v charger turns off when i just plug the chable in the phone , and turns back on when i take it of the phone (like the phone stopping the electricity )
so i want to know whats faulty , is it the charging port , or the whole Motherboard ,
PS: the electricty in that room is not good at all , after the incident i knew that i burned 2 phones charging port !

It definitely fried something, but it would be anyone's guess as to whether it fried the USB port or the motherboard without opening the device and physically examining the hardware.
Maybe the soldering on the pins connecting the USB port to the board were weakened from heat over time before this then applying a different power source was too much for them. The soldering on the USB port pins becoming weaked over time due to heat is a common issue that is usually solved by "re-flowing" the joints with a professional soldering station but that won't help you at this point. If it just burned the soldered pins, a professional shop could replace that for you, the part would be cheap but the labor charge to do the work might not be cheap. A lot of pro shops don't even replace the USB port, they just replace the motherboard so they can charge you more for the repair.
If your device has a the USB port connected to the main motherboard, you might need a new motherboard. If your USB port is soldered to a "daughterboard" separate from the motherboard, you can probably just change the daughterboard itself with a new one to fix the USB port. This would be the best case scenario because you could fix it yourself with the help of some YouTube videos without needing to pay a shop, it's a much cheaper option than professional repair of your hardware. Pro shops would probably just replace the daughterboard instead of replacing the USB port.
Worst case scenario, you might have fried the motherboard where the battery connects to the board, in this case, you might need a new motherboard. It is doubtful this kind of damage occured because there are other things along the way that would have faulted before it got anywhere near the battery and its connection to the board, but it's still "possible" so I'm including it on the list.
That's all the things I can think of off the top of my head.

Unless you can find a shop that will replace those components for less than the cost of a new motherboard, if replacing the motherboard is cheaper, replace it yourself. Just make VERY certain that you find the correct motherboard, down to the tiniest detail. Match as many numbers on the components as you can when finding a motherboard. Many motherboards a very similar with minor differences, these tiny differences can be a serious roadblock to getting the motherboard to work in a similar device.

nevermind , there is no such shop like that where i live , and changing motherboard not gonna give me back my data since am concerned about the data on the phone more then the phone it self , so i'll just buy a new phone and continue living

Well, that sucks. There are ways to retrieve the data from the dead motherboard but it involves some very technical equipment that I'm sure you don't have access to. You can investigate whether you think you can afford or understand how to do it yourself, if the data is important enough to you.
