Hi, my Samsung S2, it worked fine till a few days ago, but it has stopped recognizing any sim card (it even tells me to insert the sim card when it is inside), also since it doesnt detect the sim card, is stuck in flight mode.
I wanted to update the firmware to see if this fixed but i cannot do it because the pc wont detect it, (it charges but i dont get even a notification window that the cell was connected), (i tried 3 PCs and 3 Cables).
All other stuff works, i just cant use it as a cell phone or connect it on a pc.
I tried this with no results:
- restore stock settings.
- Master reset, formating data and cache.
- tested with usb debbuging on and off.
The Phone is a GT-I9100 with 2.3.4 (never rooted)
Help Please
I just noticed it says IMEI Unkown now, could this be the cause. if so how can i fix it if i ant conect it to a pc?
EFS corruption most likely!
Search for EFS backup or EFS restore, that will point you out to a number of threads.
Try to flash a stock rom via Odin, you can get into download mode, and open up Odin and see if it recognises your phone?
I just tried that, the pc wont recognize the cell even in download mode is there any way to flash a stock rom without pc?
Do you have the drivers installed on your PC?

So the ota screwed up my phone. I was able to connect and intstall the stock eoh3 for xda the phone now starts up but I am unable to connect USB to root or flash any new rooms with Odin I can only connect Odin if the phone is booted up and debug and mock locations are on. If I pull the battery and put it in download mode it will not connect to the pc it just shows as an unknown device. I have reloaded drivers ect but not getting anywhere. Any ideas?
Try another cable if you have one, and try putting the drivers on another PC. For reasons I still haven't figured out, my home desktop PC quit connecting a couple of ROM's ago, and it won't even let me reinstall the drivers. I have a laptop that works fine (so I haven't gone into major troubleshooting) and my work PC also connects fine.
If the same issue repeats on other PC's and cables, there may be something wrong with your mini USB port. I had to have mine replaced a few months back.
Hi all,
i rooted my sgs2 i9100 with the instructions from galaxys2root.com. I installed cwm through odin and then a cm9 nightly. Soon i noticed that i cannot send sms from cm9 and tried to reset everything back. Now windows no longer detects my phone at all, when i plug it in, i get a message that the device is not recognized, and it has malfunctioned. On linux i was able to see the device in download mode just fine and used heimdall to put in a stock kernel from a zImage. Now i have no warning triangle, but sms and windows usb connection still doesn't work. I've done full factory resets etc, currently i have the rom i backed up before inserting any custom roms, which i got through cwm restore.
What should i do? I've tried almost everything I can find with 2 days of googling and searching forums (different pcs, cleaning, usb debugging mode, pda/modem mode etc).
Edit: Ok SMS sending problem seems to be caused by the operator. I just tried my sim card in a different phone and I get similar errors and I am unable to send SMS. So ignore the SMS part, now the only problem is that I can't connect my phone through usb with windows and use odin etc.
FIXED
Ok bois i finally got this stuff fixed. There's plenty of people with the same issue and lots of different replies. Frequently a tip came up with dialing *#7284# and switching the usb between modem and pda, leaving pda mode on. Well this wasn't quite enough. I did this, but finally got it working when i first put the usb to MODEM mode, then rebooted, then switched back to PDA mode, and voila it's working! So, in conclusion this fixed mine:
1. Dial *#7284#
2. Switch usb mode to MODEM
3. Reboot phone
4. Dial *#7284#
5. Switch usb mode to PDA
Hi
I have replaced my screen on my i9305 and i have lost my imei number. I have found threads on how to restore this but when i plug my phone into the laptop it is not recognized but just charges. I have tried different computers and have tried options found on different threads but still cant find a solution.
The phone is running 4.1.1 and is totally standard as bought.
Are there any options left for me?
Cheers
You simply restore your backed up EFS folder .
No connection suggests bad cable bad port on phone or no USB drivers on PC .
Or pay for a service repair .

I have tried 3 different cables and as many different computers but to no avail. I have downloaded the drivers but every time i plug the phone in it does nothing
I have tried everything i have come across;
Installing/uninstalling Kies
Kies wont connect to phone via cabe
Wiping cache and factory reset
Checking/unchecking debugging mode
Installing/uninstalling drivers
Pulling battery with power on
Tried in download mode and upload mode
NV reader wont recognize phone when plugged in
Odin wont recognize phone when plugged in
No messages appear when plugged into pc
Swipe down in notifications shows nothing
Is there anything else i could try or has the phone had it?
Thanks
Ok so i tried to install a new rom because my AOKP Rom wasnt connecting to my PC so i thought.
Ok so here is the problem. Half way through installing a rom, some how my phone crashes, after waiting 5 hours just incase i ripped out the battery and thought i will reinstall a rom that works the CWM. Nice and easy so i thought until i couldn't access CWM. So now i have a non bootable block of plastic and a screen.
Next i put the phone into download mode expecting to use Odin to just reinstall everything from scratch however my computer cannot recognise my Device. It says USB device not recognised and doesnt show up a drive letter on my computer. Any ideas of how to fix this?
No 1) let me make this clear it is not a driver issue, as all the correct drivers are installed and my girlfriends GS2 works fine.
No 2) it doesnt matter which computer i try to connect it to it wont work.
No 3) i have tried it with and with out Samsung Kies.
No 4) The batter is charging so the port cant be completly dead.
So how do i install anything on the phone if a computer cannot access it?
I even thought of trying to use killdisk to wipe any dodgy partitions but of course this wont recognise this device as a drive letter.
Please please can any body help or should i just assume the usb port is Dead.
Hello,
I'm the owner of a galaxy A5 2016 (a510f), and I've been recently messing with custom roms (as we all do here). And yesterday I added several files to my phone using my pc, and as I was flashing a rom, this one failed.
No problem, just get back to TWRP and transfer from my pc my recent Backup, but no! My phone just won't connect to the pc, but still charges... tried transfer the backup using OTG with an USB stick, my phone still doesn't recognize
any USB connection. Tried reseting TWRP and check if MTP was enabled and it was, but still same issue. I was forced to recover an old backup I had on my phone for quiet a long time. But maybe it would work if I tried to transfer once
booted in android... Nope still not working, despite having USB debugging and MTP enabled. You have to admit this is very strange that I cannot even connect it via TWRP or download mode...
I'm really starting to suspect a Hardware issue... but that was so sudden... I also tried several USB cable, still not working but still charging.
I really need help, this is really annoying, I can't transfer anything using USB cable now, and can only use wireless transfer.
