[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.

Edl mode specific in one thing. You can start flashing only a few seconds after going into edl. After that qfil will still show phone in edl but flash will fail.

Restart to edl, connect and flash in shortest possible interval, have everything set-up in qfil in advance. Only connecting to pc is not enough.

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.

Phone stuck in Recovery Boot

Hey All,
My niece was using my phone, and when I got it back, it started to just stay in on the Samsung logo screen. I let the battery die, and now it is stuck on the screen that says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.
I downloaded the Smart Switch software, but didn't really get anywhere with it.
I then came across Odin, which seemed more promising. I'm using a Galaxy S10 SM-G973W. I am from Canada, and got the phone through Fido. I searched for the firmware to use, which I got from sammobile. After a few attempts at refreshing the FW, I am getting a failed message from Odin. I've attached the log messages from Odin. It says FAIL right after storsec.mbn. The version of Odin I've got is 3.14, and the PDA of the firmware I am using is G973WVLS4ETK1.
I've read online that trying a different FW might help. I am using the latest Fido one from sammobile.com.
My phone is completely useless right now, so any help would be appreciated.
Thanks!

A few more pieces of information that I have checked and tried.
1. Reinstalled drivers using Smart Switch.
2. Using the factory Samsung USB Cable, and have tried other cables.
3. Tried using two different computers. One is my main PC with two USB ports connected for a keyboard and mouse. The other is a laptop, where only my phone was connected.
4. Tried USB 3.0 and USB 2.0 on my main PC. My laptop only has USB 3.0 ports.
I have been reading some stuff about a PIT file that I might be able to utilize. I tried to extract it from the CSC file, but it says I need a password. I extracted the HOME CSC file, but no .PIT file showed up.

Another update, I've tried using Odin 3.14.4, and used Frija to get the firmware, but still not working. I am getting the same messages in the Odin log, as above.

I'm thinking of rooting the phone using TWRP. I have the recovery file, which I think I should be using, that is
twrp-3.5.0_9-0-beyond1qlte.img.tar
I have the Samsung S10 Snapdragon, so that appears to the be correct file. Then I load that file into the AP slot within Odin. I click start, then reboot the device into recovery mode. Is there anything I am supposed to do, once the phone is in recovery mode?
Is there anything else to know when using TWRP?
Thanks.

Would it be possible for one of the mods to post this into the questions and answers area? I think this is the wrong spot for this. I'm hoping to get some responses there.
Thanks!

Someone on andriod central said that the motherboard is gone. Does that sound right to anyone else?
