Root on froyo without connecting usb?

So I have a Galaxy S 4G that I can not get to be recognized by my computer via USB. It charges fine but always get "USB device not recognized". It's on stock froyo and I have tried several cables and computers as well as versions of drivers so I assume it's a faulty usb port on the phone.
I looked at this thread : http://forum.xda-developers.com/showthread.php?t=1099374
And it seems that it was possible to flash cwm from recovery and then flash a custom kernel that gave root access? But links have been removed and thread closed and replaced by one that requires gingerbread. Does anyone know of any way to root on froyo without usb cable? or have the files that were removed from the thread above?

Any suggestions at all?

Fix your USB port.

try heimdall?

Visit your local library and use a computer there to root. Having fun isn't hard when you got a library card.

Most free-to-the-public computers are so locked down that I doubt he'll be able to get drivers installed.

The ones in smaller towns usually aren't, or their security is easily bypassed with ctrl-alt-delete or similar combinations

thanks for the responses but it seems that I need to clarify that it looks like it's the usb port on the phone that is defective and not the computer. My Galaxy s3 and tab 7.7 connects just fine with odin using same computers and drivers that I can't get to recognize this phone.
And yes I did try heimdall but since the computer does not see the phone heimdall won't either
Nothing else I can do to get root? I would not mind about being stuck on froyo I just need root to install vodoo sound.

^ How do you charge your phone if your USB port is busted?
If it is charging well, then I suspect there is a conflict in drivers.

If the power and ground pins are active, it will charge, but if the data +/- pins arent' connected, you can charge but not transmit data. My USB cord did that to me, will charge, but won't show "usb mode" to connect for usb storage. Thought it was the rom, flashed 4 times, realized the cord must have a break in the VCC+/- wires.

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.
Greets!

I ordered a new USB port board, will let you know the results!

Any results after changing the usb port?

Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help

Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.

**urgent help needed ** s7 edge custom binary blocked by frp, pc wont recognise

Weirdest Problem i had on a Phone ever.

Hello,
I'm having a problem with my Unlocked Galaxy S6 (SM-G920F) When i plug the USB to transfer data from my PC, it only detects it as charging, and yes, i know i should change to MTP in the notification center, but i don't get that option, I've enabled it manually in the developers option, also enabled USB Debugging Nothing. Then I've rebooted to TWRP , still nothing. Tried connecting via ADB Doesn't detect it.(I'm sure that cable works , tried it with my Galaxy S5 mini , it works), So i went to Download Mode, Fastboot commands doesn't work , but weirdly it detects in Odin. Good, not great. I've decided to revert back to stock, flsahed the latest firmware. booted still nothing just says Cable Charging as if it is connected to a wall plug.
I don't know what do now .
Any help?

My S6 does a continues connected/disconnected loop on my laptop but on a desktop PC it runs great. Other phones also run great on the laptop so it's possible that you too have an isolated case.
A dumb suggestion, did you try clearing the cache? Try downloading Samsung Smart Switch on your PC and run the built in device driver reinstall function.

I personally think that it's a computer problem rather than a phone problem. If you flashed stock ROM only and didn't touch anything special it MUST work because we would have seen people complaining by now. I'm still holding onto the idea to check the phone with another PC. IDK, maybe you somehow blocked the phone on the laptop? (Download mode and "OS mode" are different things so that would clarify why the laptop detects the phone in ODIN mode)
