This is worked GREAT for me to get from 4.3 to 4.4.2 since I had No luck installing the OTA of 4.4.2 on my i747. Very EASY WAY.
Not sure on tripping. Mine was tripped anyway and out of warranty. Sorry can not help you on that part. Just know it runs well and shows 4.4.2 Should not do anything to a phone if worried about warranty. You are Always taking a Chance with any downloaded rom other than the one you get over phone. My opinion.
Did the manual check in settings... said up to date...
No warranty on this phone, (it's a refurb from insurance) I'm gonna see what happens...
