Hardware Emmc replacement discussion. Again…

[romchik971]

Hello everyone. In past couple years I’ve built a collection of dead switches. All of them have the same issue. 0.12a from bench. And I’m assuming it’s faulty emmc. I’ve tried to buy some cheap aliexpress replacements with no luck. I even booted to hekate with one of them, but I wasn’t able to restore HOS, and finally fell to =*==. I guess maybe there is some preparation must be done with Aliexpress emmc before soldering? I don’t have any bga programmer to check if emmc is good. I would really appreciate if anyone could share their experience with successful replacement of emmc

As far as I know, you should be able to prepare all partitions on the emmc after it has been installed on the board.
I don't recall reading that you need to do some special preparations before installing the emmc.

Note that unless you have a NAND dump from the original Switch, you can only use CFW. OFW will not work with a donor NAND image.

yeah, most guides say that I should boot to hekate even with complete blank emmc. I wonder if known good working emmc, but 8gb modules will work and let me at lest get to hekate
