hi SiliviuMik
I'm newbie but i want to share my experience :
my phone have manufacturing date : 22.03.2014
1.) i bought phone Samsung S4 Mini Duos i9192 with I9192XXUBNC1 CSC uzbekistan firmware 4.2.2
work well and ok
2.) after launching kitkat i decide to upgrade directly to version I9192XXUCNG2 using ODIN 3.10 and
upgrade gone well and smoothly with no issue ,work well until i decide to clean cache and do wipe data
3.) after data wipe and clear cache phone start to have only those 3 problem (but no before wipe):
- drain battery
- sometime i got messages can not initialize camera (but camera work well)
- and can not change lock screen picture (or i don't know how to do it)
4.) i decide to add your custom rom from
http://xdaforums.com/showthread.php?t=2592308
and doing dirty flash over I9192XXUCNG2 upgrade done
but after start it show with yellow SET Warranty Bit instead recovery mode ...*with blue on Samsung Boot Screen
after flashin i start using this one (even KNOW VOID Warranty 0x01) but time by time it showed to me an triangle on left upper side with message your phone have changes ...please use KIES to update or sent to SAMSUNG representative.
5.) i decide to reflash again with stock I9192XXUCNG2 again
- reflashed and i went well as before 2.)
again reflashed Stock Rom I9192XXUCNG2
6.) now i decide to use your Custom Firmware from
http://xdaforums.com/showthread.php?t=2592308
but before it i download this firmware
http://www.sammobile.com/firmwares/3/?download=18538
7.) and tried to downgrade over I9192XXUCNG2 now during download mode start writing with yellow after each certain upload firmware into phone and with yellow write (during flashin) :
under
KNOX Warranty VOID 0x01
KNOX LOCK .... 0x00
appear with yellow
SET WARRANTY BIT
SET LOCK BIT
SET HIDDEN BIT
SET ..... (i don't rember what)
when finished upload and after restarting into recovery mode
(Galaxy S4 Mini Logo with blue message recovery mode...) instead causal display recovery mode it
hang and displayed with red letter message knox kernele modified (blla blla blla ...)
i quickly put in download mode again and again reflashed it
(but this one is strage what i show)
on download mode now appear
KNOX WARRANTY VOID 0xffffffc
KNOX LOCK ..... 0xffffffc
....
but even with those messages i start flashin with I9192XXUCNG2 properly as 2.)
reboted into recovery mode and finishing installation properly
....
so after reflashing with I9192XXUCNG2 i set again download mode now
it showed me again (tripped message)
KNOX Warranty VOID 0x01 (from 0xffffffc)
but another one back again to normal (from 0xffffffc)
KNOX LOCK ...... 0x00
but my problem still remain the same
- Drain Battery (battery 28 - 36 hours lasting on JB,now in KK was 9 - 12 hour lasting)
- can not change lock screen wellpaper
hope those information will help anyone
i don't care about KNOX WARRANTY 0x01 but i want detailed procedures how to flash old
firmware or new ones (and to remove protection from bootloader using only last bootloader into old firmware or something similiaries)
so with please i ask how to remove protection from my phone to be able to flash any other flash seem on this forum (casually) that are marked stable and work well under...
. WIFI
. 2 Sim Card Phone
. 3G on Sim1
and no bloware samsung application and protection but with ability to install from google play
*but to have with long lasting battery mode (no battery drain) and ability to change lock screen picture .
