UFS Repair

[crackz0r]

Hi all!

I was wondering if anyone knew about any literature about direct NAND access on UFS chips. Is there similar technological pads on UFS as there are on many eMMCs that give direct access to NAND and bypassing the embedded controller?

I am not familiar yet with UFS technology, but I am assuming it has an embedded controller.

I am asking because I have a UFS chip which has a short to ground and wanted to explore locating the controller and trying to see if the short is coming from the controller rather than the NAND die itself.

Any info is greatly appreciated.
Thanks!

99.9% of the UFS controller uses LDPC, and the Android hardware encryption makes it impossible to get any information from the UFS even if the UFS works normally without the MCU. Based on these two dilemmas. Giving up is a wise choice.
