The firmware build version T989UVLH1 ICS 4.0.4 is the latest release by Samsung for T-Mobile Galaxy S2 version SGH-T989. An inclusion of “ISIS/NFC” is the highlight of this update and some bug fixes as always expected. I have no idea about ISIS, I just heard about it that its kinda payment method same as Google Wallet.
Anyway, this guide is only for those who can’t update their Samsung Galaxy S II SGH-T989 via Kies or OTA (over the air) for some reasons that their devices already runs with unofficial firmware. That’s because T-Mobile and Samsung will not send any updates on these devices anymore.
Again, I’m talking to those who runs with any unofficial ROM and wanted to return back to T-Mobile’s original firmware. Typical users who still currently runs with official firmware like – T989UVLE1, T989UVKL1 and T989UVKID may ONLY UPDATE via OTA or Kies and do not try this method. Here’s T-Mobile official support guide for you: http://support.t-mobile.com/docs/DOC-3029
To those who’s confused about if its android 4.0.3 or 4.0.4 ice cream sandwich or either already a 4.1.1 Jelly Bean version. Its already confirmed as 4.0.4 Ice cream sandwich and not 4.0.3 which was T-Mobile technical support team stated on their site. I don’t know whats goi’n on with them, its either they don’t tried the firmware first before they released it to the public (just my guess).
Here’s the screenshots of the firmware info:
(taking screenshots now change with holding down both Power and Home Key instead from previous button combination which is Volume Down and Power Keys).
