TH2830 vs TH2832

Did the patch only modify the header, or were there multiple instances that you needed to change? I can't think of a reason why the version number would need to be referenced for stored data.
KungFuJosh:
This is an older thread, but it has an eeprom dump (reply 12) from one of tonghui's handheld meters: https://www.eevblog.com/forum/testgear/tonghui-th2822-lcr-meter-review-teardown-and-possible-hacking/
I don't know if that helps us or not, maybe it will show something useful.
Martin72:
Depending on the size you won´t have to desolder the eeprom, with luck.
I used a SOIC-8 clip for reading out/programming the eeprom of my uni-t current clamp.

I don't have any intent to desolder anything on this. I have a sneaking suspicion it will wind up being easier than expected. We'll see though. Hopefully Rudi is able to dump enough data.

I have dumps of the I2C EEPROMS (the B85RC64TA, and the AT24C512)
I did not dump the two Adesto 45DB321E SPI Flashes because TV84 told me he did not need those anymore ...
Now my unit is back in my rack, which is a huge pia to pull out ... it's not trivial ....
I will dump the Adesto FLASH's if that is absolutely necessary.
The question really is: Who will decode the Adesto dumps ?
BTW: There is no need to de-solder the FLASH chips if you know what you are doing ;-)
Cheers,
