you will lose cal data and S/N and options. must be restored from EEPROM from the service menu (PW 9472) /BTD calibration/ restore BTD from EEPROM

Tried it; still no go. It adds a FORMAT step on boot, but then still resets on Boot IMG Update...
Starting to think something is truly borked, will have to take it apart and check if there's anything on the console output.

that doesn't sound good. Usually the formatting should have fixed it. Please keep us posted on your findings. At this point it seems like a bad NAND flash chip
debug boot record should be very helpful.
it may not be important but Lecroy specifically says after you clean and format the SD card (fat32) first copy the MLO file on to the root of SD and then copy the rest of the files next to it. I dont know why that should be important but maybe you want to keep that in mind too

On the official Teledyne LeCroy website, the firmware upgrade for the WaveSurfer 3000 oscilloscope version 9.2.0.5 did not approve my registration, and I cannot download the firmware because I am from Ukraine (It's very strange that they didn't ask about the color of my skin :-//). Unfortunately, if you don't help me, I'll have to discard the LeCroy WaveSurfer 3000 and switch to an oscilloscope from another company without racism, such as Tektronix or LeCroy.

It’s not racism, it’s export controls.
And another company, such as… LeCroy?!?

Slavic languages form sentences differently. It does not always translate directly.
"Not translates itself directly" is valid structure...
I think he mentions LeCroy and Tek as an example of companies that do export control and therefore which he might avoid.
Translation between slavic languages and English is more like a "explain it in your own words but keep the meaning" activity.

Translation is the art of taking a text in one language and rewriting it in another language, such that it is understandable to the reader of the target language. It’s always “in your own words” because it has to be. Taking a sentence in one language and replacing its words with the equivalent words of the target language (without rearranging, adapting to grammar, etc) is not translating, it’s just word-by-word transliterating, and is typically useless. Every proper translation is a rewording. Source: I used to work as a translator. (And I studied linguistics at university.)
None of what you said has anything to do with translation, though. A person’s native language will influence what mistakes they make when speaking or writing a foreign language. (I have so much experience with German and its native speakers that I have become quite adept at decoding what they mean when they write broken English, for example.) With that said, I don’t know any Slavic languages so I can’t “decode”, so I have to take what is written at face value. With that said, I don’t think the issue here was a language barrier, but a slip-up: I assume they meant to write “…Tektronix and [Keysight or R&S or Rigol or Siglent]”.

It's also totally obsolete and finding one requires going fishing on the various scam markets. It's a 137 pin BGA, which isn't too bad, but I'd rather not go through 5 to find one that is the genuine article! Being BGA I'd also want to reball with leaded solder paste.
Debating whether to bother with this or to sell it for parts... I might take the board out to take a look at the other side to see if I can put it on a heater - but I suspect it's going to have a bunch of passives on the opposite side that would need to come off first for that.

were you able to find a UART debug port and look at the boot record?
