GT-I9300 OTA for BTU region – I9300XXBLH4 (Jelly Bean 4.1.1) OTA
Courtesy of almighty Samsung-Updates.com
We provide OTA update for Galaxy S III (GT-I9300) – BTU region
to the I9300XXBLH4 (Jelly Bean 4.1.1).
Lets start with simple flash instructions as many got tricked:
1) Install GT-I9300_BTU_I9300XXBLG8_Android_4_0_4
This is I9300XXBLG8/I9300OXABLG8/I9300XXLH1/I9300XXBLG8 version.
or the GT-I9300_BTU_I9300XXBLG8_Android_4_0_4
There is a confusion on which one of those two our OTA update works.
2) Make sure BTU is your CSC, and do a factory reset from recovery – why not :)
3) Flash OTA GT-I9300_BTU_I9300XXBLH4%20%20(OTA)_Android_4_1_1
Should be booting now :)
If not we will wait for one of many users that succeed to share their flash how-to.
