eMMC exchange question

[Schn1ek3]

Hello,

unfortunately I haven't found any information about this, so I'm asking here.
Is it important when changing an eMMC that it is the same as already installed or can it also be a different one?
Installed is a SKhynix H26M74002HMR
It is not so easy to find.
Is it possible to install another one instead of the SKhynix, e.g. Sandisk or similar?
Or can this lead to problems e.g. online nintendo services with the OFW

Many thanks for your help

I have swapped an SK-Hynix with a Samsung no problem, same size 64GB and restored the dumped NAND from SK-Hynix onto the Samsung in Hekate.

Is your samsung brand new or from another oled?

It was new, not sourced from another Switch

what's your procedure to make OLED boot with the new chip?Do you program it off the board first?

The basic gist of it is I dumped the SK-Hynix in Hekate first onto microSD, swapped the Hynix with Samsung using hot air station and solder paste with stencil, booted back into Hekate and restored the Hynix dump to the Samsung.

It doesn't matter, you can use any brand of emmc. But Samsung is recommended.

Dump old emmc, install new emmc.
If Picofly or a instinct chip with newer firmware it boots up to empty emmc.
Then you can restore your dump.
