Galaxy S9 SM-G960U Remove KNOX/MDM

[SaiLas]

I have SM-G960U1 (originally G960U by Verizon). Phone came with Knox lock android ver. 10, Im downgrade it to G960U1 firmware G960U1UES7CSK2 andr. 9. Try to remove/bypass knox but nothing works.
Is it possible?

Hello
There is no knox/mdm remove function GCPro please check www.gcprokey.com for supported functions.
Its technically not possible to remove via 3rd party software even.

You call it "Samsung Account Verify(Reactivation lock)". All I needs its enable ADB, but and this function not works with emergency call screen. Log say Unsupported bootloader and bla-bla-bla.
I see "Samsung all model instant REACTIVATION/FRP Online via credits" but not understand what is mean: is it frp (google lock ) remove only or Samsung Account Verify(Reactivation lock) too?

Hello
FRP = google factory reset protection.
Reactivation = samsung factory reset protection AKA samsung account lock.
MDM = Mobile Device Management enroll facility. This lock limite phone boot unlocking,custom flashing many other thing which is restricted depend on MDM enrolled company.
KNOX = samsung security which provide most 3rd party company to implement their on way of lock customization on android level. this way samsung do not need to modify firmware. handle by trustzone with his own Operating system call mobicore.

GCPro "RLOCK Online" = all lock FRP/Reactivation disabled removed officially instant 24/7 . Just need to select modem port and must have credits to use this function in your GCPro. Full details check http://forum.gpgindustries.com/showt...ll=1#post76482

Thread you started with MDM not with FRP or Reactivation lock so please explain more what exactly you looking for ?
I hope my answer help you.

This is Knox guard some people write that this is MDM lock.

[stanner_austin]

Hello
This is "MDM" = Mobile Device Management enroll facility. This lock limit phone boot unlocking,custom flashing many other thing which is restricted depend on MDM enrolled company.

Ok, thanks. Its a first time when I have samsung in this state.
Already Knox problem I resolved with COMBINATION_FAC_FA80 and root. I changed IMEI and Serial number, this mdm lock is gon, but now a new problem. Im back original IMEi, flash stock G960U1UES7CSK2 9.0 and now phone in Emergency calls only.

Restoring QCN backup not solved a problem, with imei all good, baseband is Ok too, but in servicemode IMEi certi: FAIL


I think some way imei cert is corrupted. Trying Patch Cert with GcPro

Hello
all samsung use imei cert . if knox is 1 u can't write cert atlast on qcom.
You can use 3rd party imei repair service(if knox 0) in such case because there is no cert backup on qcom. but you can backup QCN and security block modemst1/modemst2..
