调研方向

首先,在本地构建的内核上复现 kptools 命令,并将其输出与未打补丁的镜像进行比较。调查报告中指出的缺失符号,包括 memblock_phys_alloc_try_nid 以及 CFI 和 execve 符号;当打过补丁的内核正常启动、recovery 能够启动,并且充电达到电池百分比时,即表示完成。

描述

Currently, there is no immediate solution. You need to troubleshoot it yourself or provide the device to me for further investigation.

As i am aware, i feel like getting my phone experimented on. While i can't send it to you or finance it's ownership, i can instead test on it for you.

The following is the output of kptools:

The end result is device stuck on logo (not bootlooping). The same happens on attempt to boot to recovery. Also, the powered off charging animation gets frozen after appearing before it shows battery percentage. I have built the kernel locally and it works before the patching process. Feel free to guide me to patch kernel sources or change kernel config in some way as i can do that good enough for it to boot.
