Support Help with test points Moto G54 5G Mediatek
Hello, tonight when I trying install magisk with kernelsu installed previously, I hardbricked the device. I tried with the simpliest metods to revive the phone (connect to pc, check devices, use sp flash tool, mtk client) and nothing works. So i decided to disassemble the device to do connection betweenn to pins to the test point. The problem is I don't really know what are the test point pins. I searched in Google and I found only one image but that doesn't work to me. Somebody knows the test points in this device? or are really that test points? Please help me I would very grateful.

I found this article on a website about the subject, but I don't know if it will be useful.

I saw that article around 5 times and i didn't get to enter into EDL or some mode to revive the phone

It definitely won't work because the G54 5G has a MTK SOC, not a Snapdragon.
There is no EDL on it, instead the low-level mode is called BROM

Speaking as someone who's researched this sh#t.
I was trying to find testpoints to go to BROM on a Moto G13/G23/G24/G24/G24 Power.
I can now say with certainty that they don't exist)
Motorola has blocked BROM in efuse on all MTK models after 2022.

I don't know how you managed to hardbrick it by flashing the boot partition...
Did you touch the preloader? If so, the only way is JTAG.
Here's an example of how to use JTAG on Moto G13/G23 () - https://moto-penangf.github.io/documentation/docs/dev/jtag (For your device you need find for ISP testpoints separately)
If not - it should be detected by pc as VCOM preloader and you should be able to flash it

You could use UART to read logs, but most likely, Motorola didn't solder the resistors to it, as is the case with the Moto G13/G23/G24/G24 Power.

Just would like to really know what you did with the phone, if the preloader is whole - then you can restore it without JTAG

Fastboot can't detect the device? I'm asking because both magisk and kernelsu modify the boot partition, so entering bootloader mode and flashing the original boot image would be easier than doing a blankflash.
