a7iv USB Error on macOS and Linux

[noyhrynban]

Currently trying latest (2590782)
I am needing to unlock the languages on my Japanese a7iv and I am running into the same failure on Mac (12.4 Intel) and Linux (Ubuntu 22) (the stack traces look the same anyway).

@noyhrynban did you find any success?

I have just gotten an A7iv from Japan but with no Language change option! I was wondering if it is possible to change to English?

[FakieSui]

Hello @rishabhmhjn same for me, did you find any clue to get it to english? #321 seem to show that it is not possible yet

Not yet! I look forward to any possible solution in the coming time

[noyhrynban]

IIRC This particular problem seemed to be resolved by running through sudo and #321 is probably closer to the real issue.

Use micro usb cable, don't use type c .I tried all day and finally figured it out.

Closing in leu of #321

This issue is closed but not without a clear solution. Luckily, I found a solution for this myself:
In the a7s III settings, go to セットアップ (The yellow briefcase icon) > USB > USB接続 > and change it from オート (auto) to マスストレージ (mass storage). Even though the camera automatically showed "マスストレージ" (mass storage) when connected to the PC (Mac with Parallels Ubuntu in this case) via USB connected, unintuitively, out of all the solutions, this one worked!
