You might like to consider a conversion to 465 if you have HWID 0827 [gets LA but no JCV], it's pretty safe if you retain HWID using hybrid fw but not so if you do a full flash to HWID 0943 using full 465 fw.

Some suggested reading:

[Only registered and activated users can see links. ] pages 7 & 8 re SG conversion, and particularly [Only registered and activated users can see links. ] if you wish to convert to 465 also [Only registered and activated users can see links. ]

If you want just TTS in your 205W you can flash a [Only registered and activated users can see links. ]. If you convert to 465 you may have to flash a new logo anyway, either senior 2x5W or 465 logo. [Only registered and activated users can see links. ].

Thanks for your details reply Neil.
Based on your suggestions i have decided to upgrade my 205w to 465. As per the instructions in Method 1 i got the below GCD files for 205w and 465.

The only issue i am facing is in Step 3, it says "In the Overrides section, check HWID and enter 1273 in the field. Press the RGN button to save the modded fw as 127301000xxx.rgn". Will it be the same 1273 for 205w -> 465 as well or something else?
