I'm having problem flashing modem rom to SHV-E370K (Korean version of I9195).
Originally I tried to flash full KitKat CM11 nightly rom. This went fine, but modem was not updated (baseband version stayed the same - E370KKKUANF1). Then I tried to flash european version I9195XXUCNF7 - no luck. Odin failed with "secure check fail sbl1". Flash with I9195XXUCNE6 gave me same result. Then I tried to update modem only by using flashing "Modem-I9195XXUCNE6.tar" via Odin - again I got secure fail (this time for modem). Finally I flashed back the most current Samsung rom (E370KKKUANF1_E370KKTTANF1_E370KKKUANF1_HOME) and tried flash either of those european modems onto this rom - same secure fail issue.
Now I have no idea if I can update modem at all until Samsung releases KitKat update specifically for this Korean version. From my perspective, it should not be a problem, as model is still I9195, and any rom and modem should be able to go in, right? I don't care if LTE works - all I need is regular calls, that's it.
The reason I want to update modem is constant signal loses - phone connection is up and down multiple times a day. I hoped that new firmware would help with that.
So, is there any way I can flash this phone with latest modem rom?
Thanks in advance for help!
P.S. I'm using this phone in US.
