You can't root if you are on 4.0.2.a.0.62 ( its impossible ) you need to be on either .58 or .42May i know what you want to backup ??

I clearly mentioned in my guide

Its your wish if you want to stay on it but i suggest you to repair your phone software using SUS. It will reinstall the original ICS software in your mobile 

is your bootloader unlocked, if yes then you can't use SUS or PCC

rest i was not able to understand what you wrote, seriously Anguished Face Thinking Face, i read thrice,

Oops, no one is facing that problem, i doubt the cause may be some app
uninstall all the apps ( that  you installed after installing ICS ) and see if problem exists

Generic and nordic means the same. After repairing with sus , it will reinstall the firmware the phone carries ( means nordic, ics is not yet released in India  )

Yes, actually there is no indian rom but Asian rom that you will get . But remember you need to downgade usig flashtool and then upgrade directly through pc companion.

SUS downloads compressed files so that it eases customers. later while flashing it extends them and flashes Slightly smiling Face

Sorry to make you confused  Dizzy Face

I tried flasing the ICS rom and everything worked beautifully,  now my phone runs ICS rom :smileygrin:

Thanks for making this process simpler and easy to understand.

I have not repaired my phone using PC comapnion, i believe that it will reinstall GB rom back ?? {i am from india}

Also i have donwloaded the GB rom you posted somehwere in this thread would degrade to GB once the official update is available .

And i have not rooted it !!

no it wont .. i repaired from SUS and it installed ICS on my phone only (official nordic one) so you should also repair from SUS
