[blazzer12]

Should I use this kernel or the one provided by the latest GSI image?

 

[RISHI_k]

this kernel is overclocked to 1.7 GHz, but its original frequency was 1.6 GHz.
how much performance enhancement can we see?

Thank U for this long waited update Sir!:good:
It is a really great work, brings finally custom kernel for A750 to the PRO level

Nice to see that the kernel got updated, the last time I installed this on my stock One UI 2.0 I got the Samsung Pay thing so I'm scared of installing this now.

Everything got fixed as it was initial build

before i do something extreme, there's any way to pass the "your phone is encrypted for security to start up your device enter your password"? I don't have a password just a 4 digit pin and fingerprint, and writing the pin doesn't work, if I can't get my data back I'll have an excuse to wipe and install Havoc that's good.

thats because of dm-verity, if you flash on stock kernel, you need to flash that dm-verity

 

[gigi_13579]

Great, thanks for the update!

One Question: Is it possible to keep Data Partition encrypted after flashing this kernel?

No, encryption won't work

 

[gigi_13579]

No, encryption won't work

OK, thanks!

Thx for that update which probably fix most of our minor issues away for a while? Another little hope for A750 to stay alive a bit longer.

BTW - appreciate a lot Your work on 7885, especially your patience on asking for an update, force release and bugs claims?

Keep it up, we need kernel!
