First of all, you should carry out these steps in order to make sure if your cell is UBS Bricked or not:-

1) Try reinstalling Kies.
2) GOOGLE DRIVERS for your phone.
3) Try connecting via another pc usb port.
4) Try on different PCs or format the current one and try again.
5) Try using different usb cables and wall chargers to check whether its detecting and charging or not.
6) Mobile Odin[Not yet compatible with our device though. Chainfire is working on it.]
7) Clean your phone's mini USB port with the help of a toothbrush or a toothpick or blown air.
8) Use USB Jig [I WON'T RECOMMEND IT AS IT IS TOO DANGEROUS AND CAN HARM YOUR MOBILE]
11)Try toggling Bluetooth and then connect to PC. Check if that works.
12)Having the phone connected to PC and then turn on the PC.

IF THE ABOVE STEPS STILL DOESN'T WORK, READ BELOW

My case:-
-Rooted
-CWM Recovery Installed.
-Download mode accessible.
-Won't detect on any PC or laptop or any other. Even Odin won't detect it. Same when phone is in download mode. [Kies reinstalled & updated. Google drivers for our phone installed]
-Won't charge via a wall charger or USB cable either.
-Won't charge even when turned off and wall charger connected to it. Only the charging logo keeps flashing. But doesn't really charge.
-Won't charge even after wiping cache, dalvik cache & battery stats.
-Won't charge even after flashing different kernels via CWM. Nor does it charge after flashing stock kernel.
-Won't charge after flashing different ROMs
*Charges when connected to PC continuously for the third time.

NOW DO FOLLOWING STEPS TO GET BACK ON STOCK ROM, UNROOT IT AND GET BACK ON STOCK RECOVERY SO THAT YOU CAN GET IT REPAIRED WITHOUT VOIDING YOUR WARRANTY.

**IMPORTANT:- Make backup of your /efs folder using any Root Explorer before doing anything below. Keep that backup on your SD card. In case your IMEI gets messed up, it is the only way to recover it.**

1) First of all, make sure you do have a CWM backup of your country's stock ROM with no root. If you don't have it, tell your friend to do it. Then get that backup on your SD card so that you can restore it.
[Worked in my case. But I'm not sure if it also restores /efs from your friend's cell. If it does, your IMEI might get changed. DO IT ON YOUR OWN RISK].

2) If you've done the step above, start from here. First, factory reset on the current ROM you're on. Let it reboot. Now shut it down again and reboot into CWM recovery. Wipe cache, dalvik cache & battery stats.

3) Restore the CWM backup of your country's stock unrooted ROM which I've told you in the first step. To do that, go in CWM recovery-->Backup/Restore-->Restore-->Select your file-->Select YES.

4) After restoring is complete, let it boot successfully. After it gets settled, again factory reset. Again Wipe cache, dalvik cache & battery stats. Reboot.

5) Let it reboot completely. NOW TO UNROOT your cell, remove apps that you pushed to /system/apps (and superuser at the end) with root explorer and do a factory reset. Let it reboot. Download Root Checker from Market and check the status. If it says "Not Rooted", then congratulations! You've successfully unrooted your cell.
[Or just flash "unroot.zip". Now repeat Step No.2 again.]

6) Now again repeat step 3. After restoration, again factory reset and let it reboot.

7) Now to go back to stock recovery, download the file I've attached in this thread and put it in your SD card. Reboot into CWM recovery. Install zip from sdcard-->external_sd-->stock_recovery.zip-->YES.

8) Let it reboot. Again switch off the cell and go to recovery. Check if it takes you to Stock Recovery. If yes, then you've successfully got back on stock recovery!

Now you can give your cell to repair without the fear of voiding your warranty and save your ass from paying the expensive repair cost!

(*I'm not responsible for any harm caused to your mobile as there is risk in every ROM,Kernel,Mod etc. you flash on your cell.*)

You might wanna check out the fixes below but I won't recommend them because they are not safe at all. Do it on your risk:-

Guys, I am in a very damn serious problem!

I was testing [XWLA4] based Lidroid ROM v3 a couple of days back. Since I wanted a better music experience, I flashed ardadat kernel v1.7b2 which is specifically for XWLA4 based ROMs. Till now, my phone was getting detected on my PC with "USB debugging mode".

But after like 2 days, it stopped getting detected on PC and charging via a charger or USB.

I have tried factory resetting and hard resetting the cell, its still not working. I also tried wiping the cache, dalvik cache and battery stats, its not working either.

I still tried and when I connected my phone to the PC continuously for third time, it detected for 5 seconds and again became undetected.
It charges at the 3rd reconnection to PC though. But not via a wall charger.

I had CWM backup of my old & original Indian Galaxy R ROM. So I restored it but its still not working.

The phone is not even getting detected in download mode so I could flash the stock ROM.

I have tried connecting my phone to other PCs but its still not working! I tried re-installing Kies, Samsung's USB drivers for their android cell and everything. Not working either.

I tried uninstalling and then reinstalling Kies, updating other drivers and all. Didn't work.

I think the problem is in the cell because other USB devices are getting detected on my PC. Just not my cell. [I will try connecting my sister's S2 to PC and will update here]

I have also tried flashing another kernel, Still not working.

Can someone upload CWM backup of unrooted stock ROM? I wonder if that works.


Can someone of you tell me how to fix it?

Or is there any way to remove root [unroot the cell] so that I could at least give my mobile to repair?

Hey buddy, check this thread for alternative installation of CWM:-
http://xdaforums.com/wiki/ClockworkMod_Recovery

There is a yellow triangle removal app available on the Play Store. It also reset the download/flash counter. It's made by Chainfire. But sadly its only for devices running ICS.
https://play.google.com/store/apps/...ic&utm_term=remove+yellow+triangle+play+store

Maybe you should wait till Mobile ODIN supports our device. You should help Chainfire to make him support our device by providing him some files.

Refer to the threads below. These methods will/might work.
