SD card End-Of-Life on LM3V2

[Tinysprings]

Hi,

I'm trying to upgrade my LM3 V2 to the latest version : lm3v2-20211215.img

Unfortunatelly, firmware doesn't flash and I can't even restore the latest project backup which has now come back to an old version from May 2021. Even most recents Objects log are from that date...

So reading some other threads, it looks like my SD card has gone wild, the original Samsung 4Gb.

I ordered two industrial SD cards, WD 8Gb and SanDisk 16Gb (no SLC), that I should receive next week.

Time being I would like to know If I've got everything needed to restart from scratch.

Here is my current LM/CPU :



Is "recovery-mxs-1g.img.gz" the right recovery image to flash first with USBIT ?

By the way, is there any trick to make use of the extra space on the SD Card, I mean use the 4 to 12 extra Gb after the 4Gb initial allocation made when flashing the recovery image.
Would resizing partitions work ? Some of the new cards seems to have an internal wear management like SSDs. Having more available size would spread the wear on a bigger size and probably extend the card life.

Thanks for the help.
