[Q] my phone keeps connecting and disconnecting via USB

Hello everyone,
i've got a European Samsung Galaxy S with this 2.1 firmware and it's working with no problems:
PDA I9000XWJM2
PHONE I9000XXJM1
CSC I9000NEEJM1
i tried to update my phone to Android 2.2 via Kies but my phone just doesn't get recognized by the computer in Kies Mode or MTP mode, i have the latest version of Kies 1.5.3
and i even tried to download many drivers packages or manually extract the drivers from Kies and manually install it via device manager.. also all of this doesn't work!
i noticed something weird with my phone when it connects to Kies and the computer is trying to install drivers, the blue screen of the USB cable on the phone keeps disappearing and reappearing repeatedly and i hear a sound of plugging and unplugging from the computer.. it keeps doing so in MTP mode and kies mode, but not in USB mass storage mode as it works normal..
i thought even if i could get the driver to work my phone maybe has an issue with it's original firmware or something..
note that i haven't modded this firmware or rooted it before, this is what came with the phone..
another thing i've tried to enable the 3 button fix the download mode.. but it needs a rooted phone, so again tried to root with the SuperOneClick it works with some command lines appear but it just keeps looping through them and connect and disconnect forever..
i even want to make the lag fix but i can't too..
i'm very frustrated and i'm thinking to sell the phone as i can't do anything with it i can't upgrade it or even fix the lag, the phone is working but doesn't like to be connected to the computer!
...
i would be thankful for your advices
is my phone has a fixable issue or it's useless..

I would love to he anr to this. I am on the same boat.

Few things you could try...for USB disconnects!
1. Uninstall previous Drivers and Reinstall with new Samsung Drivers
2. Go to Device Manager in Windows (presuming you are using Windows)
Uninstall all The USB Root HUB's and everything else under the tab if you can, dont worry Windows will install again on startup
Once all is uninstalled ..Reboot!
3. Try a different cable
Hope some of this helps

Try to boot to download mode (after reinstalling the drivers)
Reflash firmware you are looking for via kies or odin. I ADVISE to look for stock firmware, before flashing any custom roms.

I am not able to put it into download mode.. the most i can do is just wait for it to stop blinking and quickly put usb into pc... but any software niether oneclick unroot nor odin would show any sign of connection of new device!!

The drivers are probably not installed, or need to be reinstalled.
First, you should try using the zadig.exe driver installer that comes with the Heimdall bundle (just Heimdall, not OneClickUnbrick). Plug in the Tab, Click Options -> List All Devices, then click Samsung USB Composite Device and install the driver. That should most likely make it detectable by OneClickUnbrick.
If that doesn't work, try downloading the Samsung USB Driver for Mobile Phones or Samsung Kies to install the needed drivers.
Finally, you can try getting the drivers to install automatically by plugging in the Tab, then going to your Windows system tray, right-clicking Safely Remove Hardware and opening Devices and Printers. From there, you should try to find your Tab's device listing (it's usually Samsung USB Composite Device), right-click it, and select Remove Device. Then unplug the Tab and plug it in again.

Odin One Click - Blank Boxes

For some reason, on both my PC and Laptop(running Windows 8 and 7 respectively), One Click refuses to work

Normal Odin detect the phone and works fine, same for Heimdall(I ended up using exodin and heimdall-ing them, since I have no idea which file goes into which tar.md5 for odin). Any ideas?

Yes. If I switch to the Samsung driver, Odin works fine(normal Odin). If I switched to WinUSB/Heimdall Driver, Heimdall works fine, except for the get .PIT function.

okay, so put a tar file in the pda slot in normal odin 1.85. the other odin 3 standalone odin doesn't work with captivate. at least thats what i recall reading. I use 1.85 and never had trouble getting it to see cappy, including labels on the boxes.
it looks like you are running 1.81 and something in your PC setup is preventing the labels from something. try odin 1.85.

I get blank boxes in Odin when I forget to run it as Administrator. My PC is running Windows 7.

Is there a OneClick version of 1.85/Anyway to make a 1.85 OneClick? I can flash em with Heimdall, but its a little annoying compared to click and do something else for 10 minutes. 1.85 normal odins see it fine, I used it to flash the CWM kernel.
@Val D. Tried it all, Run as Admin, compatibility mode XP.

Captivate (I897) Not Connecting as USB Device on Windows

So recently I decided to dust off my Captivate and install a custom recovery on it using Heimdall. I installed the drivers from Zadig and was preparing to flash the recovery when I had to take a break. After plugging the device back in (in download mode) a few hours later, re-installing the drivers, and attempting to flash for the first time, I got an error telling me that no compatible device in download mode was detected. I reconnected the Captivate and went back to Zadig AND Device Manager in Windows to see what was up, and the phone didn't show up in either. I toggled "Hidden devices" in Device Manager and finally got something:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As you can see, it failed to connect. I disconnected and reconnected my device multiple times in both normal and download mode, and sometimes it wouldn't show up at all, even with "Hidden devices" on. Whether or not it showed up didn't seem to follow any pattern. I have even tried on multiple Windows machines at this point, getting the same result every time. My phone is working just fine besides this one issue and running the stock ROM. Any help would be appreciated!

Hard Bricked MI A2

Hello everyone, last night I tried to do the conversion of an Mi A2 using the qifl in fedora 30. In the middle of the process, after giving the command sudo qifl --debug prog_emmc_firehose_Sdm660_ddr.elf rawprogram0.xml patch0.xml, I do not know if by bug in the program or problem in the cable, the computer lost the connection to the cell phone while sending the system. Now it only turns on and stays on the Mi screen and also in fastboot mode, but in none of these modes is it recognized by the computer. Seeing some tutorials here in xda, I also tried the test point method to enter EDL mode, but I do not know if it is a problem or if I am not aware, because it also does not enter, usually or nothing happens or the Mi screen appears when I insert the USB cable.
Could someone give me a light?

Try using another computer, and connect your phone via FAstboot, remember to install all the drivers.

I have only worked on Windows for flashing phones, on my experience once te phones powers up, it could be fixed, The only thing I could imagine is that your problem occurred due to bad connection between the computer and your phone.
Since you had already installed all the fastboot drivers and changed your computer and Operative systems, could think about using a diferent cable, if it works ok on other phones (prove it using usb transfer, cable can charge the phone and still be defective) if your cable is ok, try connecting your phone via fastboot, and move the cable on your connection port, cuz it could be another problem with it and try listening if the computer sounds like an usb is connected. Hope you can solve your problem.
