Bootloop on 512GB Note 9 #2

Closed cawilliamson closed 5 years ago

Hi there!

I have been struggling trying to resolve this issue for a few days now.

I have both a 128GB Note 9 and a 512GB Note 9 which I'm in the process of migrating from/to. The problem I've got is - neither ELS nor any of the kernels based on it (excluding BeastMode) actually boot on my 512GB device.

I follow the following steps:

Identical model, identical config (excl. 6-8GB RAM, 128-512GB storage.)

As stated - if I follow the same steps above but install BeastMode kernel the devices boot right up. It's very strange indeed. I'm just wondering if you have any ideas or pointers on where the issue may be?

Logs:

The logs below were taken from TWRP - from the 128GB device after one successful boot, from the 512GB device after 3 unsuccessful boots (splash loops.) As such, they may be useless but it's the best I could do. There are no tombstones generated on the 512GB device since I don't believe the boot process gets far enough to actually create them.

Ok, figured this one out:

 # CONFIG_UH_DEBUG is not set
 # CONFIG_UH_RKP is not set

Apply this patch (i.e. kill off CONFIG_UH) and two things happen:

1.) This and any kernel built from it can boot without Magisk. 2.) This and any kernel built from it can boot on the 512GB Note 9.

Hi there, sorry for the late reply as i've been very busy lately.

I'm happy that you fixed it, i will merge your PR soon. We do not need CONFIG_UH anyway.
