Assalamualaikum uncle,
in the case of the Redmi 9T, the Matot 9008 problem, but the damage is not coming from the CPU or eMmc which is often the 9008 if there is a problem.
the problem and discussion this time is in the VPA_APT producing ic, which functions for signaling,... if you look at the schematic, the ic is indeed used specifically for signaling... not for other components, but I think the occurrence of 9008 has an impact, yes, not the main cause , IMPACT, let me understand once again, IMPACT...
impact means the impact of the drop in the ic which is also supplied with VREG_L9A 1.8 and VPH Power...
maybe that's my perception,,, if there is something more detailed and scientific, please comment and clarify,,,
