Samsung Galaxy S not being seen in Explorer and will not Shut Down

I have a Samsung Galaxy S (i9000). If I connect it to PC, I can see it is charging but I can not see the phone nor in Explorer or Download Mode.
The phone is using [NIGHTLY][ROM][4.2.1] CyanogenMod 10.1 for Samsung Galaxy S and I have installed it via CWM. No matter what ROm I installed via CWM, I could not see the phone in Explorer.
Another problem I encountered is that the phone can not be shut down: if I choose Shut Down it is restarting.
Any help will be appreciated.
Thank you.
Are you on windows 8?
Install the newest USB-Driver in Windows-7-Compatibility-Mode. If you are not on windows 8 it could help anyway.

Another solution for accesing your phone would be Airdroid on Play Store https://play.google.com/store/apps/...t=W251bGwsMSwxLDMsImNvbS5zYW5kLmFpcmRyb2lkIl0.
I would try to reflash your rom to solve your other problem.
I am using Windows 7.
I want to access Download Mode in order to change the ROM with ODIN.
I do not know how to reflash it. Can you provide me more details?
Thank you.
Save your Data and make a backup before doing anything.
First of all try to go to recovery wipe chache + dalvik + fix permissions reboot
Factory-Reset would be next to try.
If wiping does not help:
Solution 1 - Odin:
Access Download Mode over Powermenu -> Bootloader
or with shutdown (in your case press power ~8 seconds or remove battery), press volume-down + home + power than flash a rom with Odin.
Solution 2 Download your prefered rom copy the zip-File to your phone and flash it through recovery (same way you installed CM 10.1). Wipe cache + dalvik in recovery.
HOWTO GET INTO RECOVERY:
- Turn off your Phone
- Hold VOLUME UP + HOME Buttons
- While holding VOLUME UP + HOME Buttons press POWER Button until Display lights up, then release only POWER Button
- Still hold VOLUME UP + HOME until you got into Recovery
- Release all Buttons
------------------------------------------------------------------
HOWTO GET INTO DOWNLOAD-MODE (Bootloader):
- Turn off your Phone
- Hold VOLUME DOWN + HOME Buttons
- While holding VOLUME DOWN + HOME Buttons press POWER Button until you reach Download-Mode
- Release all Buttons
Thank you for answering my question, but I already did all of above. Even so, the problem is that my phone can not be seen in Download Mode.

But you managed to install a working rom?
Tried with another usb-cabel, computer or usb-port?
Perhaps this helps, although i never used Mobile Odin.

HELP! S8 got bricked, can't access recovery mode and OEM is locked

Can I get some help? I bricked my phone because I was trying to install twrp. It flashed but I got an error where it reset my data, after data reset I was stuck at the boot screen with the logo
. I've tried steps like flashing stock rom, odin fails. (I feel like because of the reset my OEM got locked again)
I've tried smartswitch/kies, software downloaded but the phone automatically restarts when the software starts installing. It doesn't even detect my S8
I'm stuck at the bootlogo where it says Galaxy S8, I can't access recovery mode and also I checked on download mode, it says my OEM is LOCKED. I'm using the Samsung Galaxy S8 G950FD.
please please help.

Try this !
Prepare ODIN with the files CL + BL.
This worked for me this wait, my phone was like yours...
I Cannot turn phone off too.
There's a trick...
All the time you enter in Download mode, and hit Start in Odin, the Odin says "FAIL" and the phone automatic reboot.
The trick is..
When in "Download mode" Start and at the same time press and hold "Vol Down + Bixby + Power".
Odin says FAIL and it will restart the phone automatic.
Press faster and hold "Vol Down + Bixby + Power" to go again to "Download mode".
Press Start in Odin and be prepared to press and hold at the same time "Vol UP + Bixby + Power".
Odin will start to transfer the files... and after that the phone reboot again faster, just press and hold one more time and faster "Vol UP + Bixby + Power".
TWRP will start !
Hope it helps
Okay this one worked. It flashed. Great. But now IT STILL DOESNT BOOT. I'm stuck at NO COMMAND, it keeps restarting after 2 second of showing no command. and it's looping all over.
Note: I've tried reflashing the ROM again. It now fails, and the trick doesnt work, I've tried booting to recovery mode when its on NO command screen. It just restarts. Doesnt boot.
Having a hard time getting into download mode also. Sometimes it does, sometimes it doesnt. It just keep restarting.

Thanks for your precious reply and sorry for not updating my previous reply.
Its done. Installed TWRP successfully!!!!!
Anyways thanks for your help!!!!!!!
I guess I have to join the club. I tried to flash the new Oreo beta and surprisingly I succeeded but I made a mistake of playing around with it's arrow pattern settings designed for older people. End result, couldn't remember what sort of combination of arrows I chose. It surprised me that I couldn't use my fingerprint to get out of the arrows, it's basically a pin or a pattern so I should be able to skip it with a fingerprint.
I've been trying two days now, got beyond the arrows problem. Initially I had the original recovery but in my great wisdom replaced it with TWRP so bye bye warranty, but I trusted I could handle it so that I could get back to Oreo but no such luck. Every time I manage to boot it says my data is corrupted and I can't use it. Tried flashing all kinds of Oreos and not Oreos but no luck so far. I even tried a trick #47 to format the data folder and then reflash it with the same stuff. No luck, I've restored backups and made new ones and I suppose it's time to say I don't know what to do. I got a bunch of APKs but I can't get far enough to use them.
My next operation is got back to nougat, but somehow I doubt it will get me through this so any ideas? If there was a way to make the phone like it was when I bought it - then I could make my mistakes all over again, I'm too stubborn to learn anything ever, besides, I'm almost forty and you can't teach old dog new tricks.
I don't have official access to Oreo, just tried flashing whatever I could find on xda mostly. Any and every idea is appreciated. has anyone invented a time machine yet?

Hey there sender, thank you for posting this as it did seem to help me a lot. I was having troubles getting to that menu and it seemed to be how you say it "bricked" as well in no clue how to resolve that. I had searched up almost two hours with no luck and doing other several other options in gaining to resolve it, nothing helped.
Looking at this guide this was something that seemed to only help and thought it was worth a shot after doing over several.. thinking in finally giving up and going ahead with a new device, but my luck.. it worked!
Again thanks for the guide, hope you well and to this community.
Thanks a lot
My phone is working now
Thank you so much!!!
Same problem, but odin stuck and it says "set partition" in the box on the right top..
thanks in advance

Hi I am having this same issue. I tried what you wrote about but I am a little confused. When you say prepare Odin with CL and BL files, what is the CL file? I only have an AP, BL, CP and CSC file but no CL file. Also when you say "Press faster" what does that mean? Not sure when and what to press faster.

Is it possible you still have those files? I know it's been so long, but my phone is stuck in download mode or does nothing at the update screen.. If it helps, I totally forgot to turn on USB debugging before the last time my device saw life.

Here’s how to enter Safe Mode on a Galaxy S10 smartphone:
Shut down your Galaxy S10 smartphone
Hold the Power button key and release it when the SAMSUNG logo appears on the display
Right afterward, press and hold the Volume Down button
Hold the Volume Down button until the device boots up, and the Safe Mode text appears in the bottom left corner

Is there fix to connect my phone to pc and recovery my data, i have boot loop, can get recovery with power and up and download mode with + - volume. How to make my pc detect my phone, i use stock rom

My Samsung Galaxy J7 is soft bricked. How can I fix that? Details in the post

My phone is stuck on Samsung Galaxy J7 powered by Android screen. Holding down power and volume down buttons for few seconds make the screen disappear for a moment, the phone vibrates, then it returns to the same screen again. How can I fix that? (I guess its because I chose older .img file from twrp.me/Devices/ because the newest one did nothing when I was trying to install TWRP.) I dont have enough posts to post on the developer thread so I posted here
Please help
Approx. battery right now is 65%
Edit: I cant go into recovery mode I have tried alot of times already
Well basically be sure that you're doing the recovery mode procedure right. Try holding the volume up + power button + home button simultaneously. Then let go of the power button when you see the phone logo but remain holding down the volume up + home button. Wait for a while, the recovery mode page should pop up shortly.
Try vol. Up+power+home button. When samsung logo appears go off power button only, keeping the vol. Up and home button pressed. Check if you can enter recovery mod, if not download firmware for your drvice(download the correct latest firmware for your model) in to your pc. Flash it via odin.
