Warning : This will void your warranty. And we are not responsible if you brick your phone. But we think you can’t brick it, there will be some hope finally at the service center though. This procedure is very simple and tension free.
You should have these two files ready.
1. Spice 2.1 Update File F0X-219M-0-5015-A01.nb0
2. SUT-LR update Tool Get it – here
INSTALLING SUT-LR UTILITY:
I hope you already downloaded the Software Update Tool from here SUTLR.ZIP else download it. Extract it to some folder in your PC. Then install it by running the Setup.exe inside. Then start SUT-LR program.
Connect your phone to the pc using USB cable. Click on Next.
Browse to the folder where you copied the F0X-219M-0-5015-A01.nb0 The screen should show phone is connected.(just making sure drivers are installed.
Optionally ( I think its better to ) select ERASE DATA. Put the Phone into download mode and then Turn OFF your phone.
Start to Download Mode ( Press Red + Vol Up + Power Key )
It should show
Flash item : SAMSUNG KG45******
Modem REV FXX-2-19M-00
incoming download mod
blah blah blah ….
Don’t have to rush let it go…printing….
Phone should be connected with the USB to the PC else connect it
Now click NEXT on the SUT-LR utility
Then it should give you a screen saying, Update process is completed successfully. Press FINISH or CONTINUE if you want to update to another ROM any thing as you like. Either UPDATE Success or with an error code 0x4000 something don’t worry just try to manually switch on your phone it should work fine.
This is just because the reboot failed, Just power on manually and it should all work well.
This method can be used even on a bricked phone which is not booting.So this should work fine or else try again don’t panic J you can always go to Videocon service center and fix it if something terrible happens. I have tried it again and again it worked fine. I even came back to 2.1 and then went up to 2.2.1 .. now I am looking for a 1.6 stock rom so I can try to come back to 1.6 stock. I will update this post as and when required.
