A look at the Uni-T UT210E

Hi alex27riva. I've had problems like that with my friends unit.
Storytime......:
I've bought the clamp meter after I've borrowed the other meter from a friend and was impressed with it. After I've had used and maxed out the scale couple of times, I've found this thread and HTML based modding programs. As soon as I understood what to do - my meter was modded and later calibrated.
So I showed it to said friend and he wanted me to flash his meter too, but there was a problem! The friend said that he: did some random button pushing, measured current draw of powerful Ham radio HF setup(with grossly mistuned antenna), dropped and gave the bag to the Russian train and air luggage systems(multiple trips), oh and he had leaky battery at some point. Majorly misused the thing, you know what I mean.
Anyway I(out of curiosity) took hes meter home. What I've found was OK, the meter was in OK shape, but(due to impact, i think) the hinges of the clamp were cracked. The flashing went well and everything, but the calibration not so match.
Also I've some dodgy range switch problems on another UNI-T and HP meters, but that's more wear and tear then a defect.
There is no way to know what exactly is the problem: HF Radio interference overload, button mashing, impacts, moisture, something chemical or otherwise.
I don't want to demotivate you, just giving you ideas on what to check. Simplest thing first.

Hi everyone, I'm trying reading the content of the EEPROM on Linux using flashrom and I get the error "No EEPROM/flash device found".
I tried also on Windows 7 with CH314A Programmer (I followed this video), but is only reading "FFFFF". The programmer is connected and recognized.
I'm using this programmer from Aliexpress
What could be the problem?
edit: fixed link

Hi alex27riva.
Your Aliexpres link doesn't work.
Try sucking the EEPROM chip out and inserting it directly to programmer( with SOIC adapter).
Trouble with programming EEPROMs that are still connected are quite common. For example, some programmers have a problem with address pins(1,2,3) and enable pin on some chips.

Had the same issue with flashrom, apparently it does not support that flash. Used some Russian (I think) software under
Windows VM to flash mine.
I used this to flash (no longer available but should be the same as all other CH341): https://www.aliexpress.com/item/32354555071.html?spm=a2g0s.9042311.0.0.27424c4dd9uJHv
