[AT&T Samsung Galaxy S 5] korabiko:
BACK!

i upgraded to stock OI5...the phone kept the wifi tether with no modification needed ((of course the upgrade removed root))

BUT,even if the wifi tether was working and tested,the SHAREit app would give ''no network'' when trying to receive.

So i rooted,flashfired the G900A_OC4_TetherAddON on the freshly flashed OI5...which bricked my phone with endless rebooting. I tried flashing the G900A_OC4_Stock_Kernel.tar but the phone would freeze and stay at the very first boot screen this time.

I had to reflash stock firmware.BUT THIS TIME, I DIDNT GO TO OI5,ROOT THEN DOWNGRADE TO OF3 via FLASHFIRE,NO. WHAT I TRIED THIS TIME, AND DIDNT TRY BEFORE, IS DOWNGRADING FROM OI5 TO OF3 DIRECTLY USING ODIN AND FLASHED OF3's AP CSC CP( no BOOTLOADER)....the phone booted perfectly,and BESIDES IT KEPT WIFI TETHERING FOR INTERNET ONLY WITHOUT THE NEED FOR ROOT OR ANY MODIFICATION ((no share it receiving,though))...SO I ROOTED THAT FRESHLY-ODIN-STOCK-FLASHED-OF3 and FLASHFIRED G900A_OC4_TetherAddON and got SHAREit working again.

****************************************************************************************************************************************************************************

CONCLUSION REGARDING FULLY FUNCTIONAL WIFI TETHER (internet + SHAREit):

---------------ON 5.0 OF3:--------------

*i downgraded from OI5 to prerooted OF3,flashfired the G900A_OC4_TetherAddO = wifi tethering fully functional ((INTERNET + SHAREit))...even after you wipe the phone.

--------------ON 5.1.1 OI5:--------------

*i upgraded from that OF3 to OI5 directly via ODIN,had wifi tether working for internet with no modification needed, BUT SHAREit didnt work when receiving. Falshfired G900A_OC4_TetherAddON which softbricked the phone,flashed G900A_OC4_Stock_Kernel.tar which didnt fix it = you can get WIFI TETHER ONLY FOR INTERNT FOR NOW,no RECEIVING in SHAREit....and G900A_OC4_TetherAddON bricks OI5

FINAL CONCLUSION:

So,once i managed to flashfire G900A_OC4_TetherAddON on the OF3 i managed to :

1- get WIFI TETHER for "internet" on both 5.0 OF3 and 5.1.1 OI5

2-only get SHAREit receiving on OF3 (IO5 will softbrick if attempt to flash G900A_OC4_TetherAddON))

3- no matter if i wipe,upgrade or downgrade,i always keep the wifi tether for mobile internet ((i lose SHAREit receiveing,untill i flash G900A_OC4_TetherAddON on OF3 only))

****************************************************************************************************************************************************************************

My CONCLUSION AND TEST ON DOWNGRADING :

* i managed to downgrade fro OI5 to OF3 with both:

-----------1 : FLASHFIRE the prerooted OF3 .zip

-----------2: ODIN the stock OF3---AP--CP--CSC....no bootloader of course.

i dont know if the downgrade to 5.0 OF3 through ODIN is mentioned somewhere here,but i hope it helps,since it might be timesaving to a quick downgrade.

****************************************************************************************************************************************************************************

Now i downgraded to OF3,and left it there since SHAREit is mandatory for me.

I hope all this helps somehow

NOTE :

Here is the link for the G900A_OC4_TetherAddOn that enables full functional WIFI TETHER ((FULL for OF3, internet only for OI5))
