Open odin 3 flash modem and bootloader only , 5 minutes
Why should BT (bootloader) be flashed along with CP (modem/radio module)? Is it enough to flash CP only?
Do these manipulations affect the "cell standby battery drain"? Can anyone confirm that flashing modem from newer ROM fixes the issue?
I have flashed both BL and CP also. Now I'm charging the phone and will test is the issue gone or not.
I decided to flash original ERE8 (Nordic countries (NEE); G935FXXU2ERE8) bootloader (BL) and left EREO (G935FXXU2EREO) modem (CP) for tests. With BL from ERF4 (G935FXXU2ERF4; same ROM as where EREO modem is) Samsung Pass, Pay and Health applications were complaining about "custom OS" and saying that phone was supposedly customized and has SuperSU rights (gentle hint like I have rooted device which is not a true).
Will see if only EREO modem will fix that cell standby issue. I will report the results after few days.
@SmashMix you can see that the cell standby increases very slowly now 1h maybe 5mah
before it was draining a lot
so are you now on older ere8 bootloader but newer modem ereo?
