As far is i know, the RT809 (F or H) is very common in your country. Maybe you find someone near you. Otherwise, just buy a new AT24C08C and try starting with a empty one.

If you wan't to upload a bin file, rename it to .txt extension.
Just zip the file instead wasting forum space.

@Vasil78 Can you provide an image of the new Eprom marking?

Yes, I tried the same thing, it doesn’t work, but I flashed it with my programmer and haven’t found another one yet

Hi, @jimKnopf I made same mistake I bought the c210 station mine is XZZ FX-210 wich is the same as the jabe pro version
It is frustrating to be limited to 30w

I would really  appreciate if you could share the ud 1200 firmware so I can reprogram my station.

Thanks

@Solid_snake I send you a link via PM. Please check your Inbox.
Good luck. Please make a backup of your Eeprom and firmware first.

You know what the Admins say: No backup, no pity.

Hi, did you try placing R41 with the Pro firmware?
We have a FX-210 at work we don't use (We need C245 power), I opened it and it seems the same as your Pro  model, with R41 unpopulated.
Now I wonder if all it needs is R41 to work, or also the full firmware?

Edit: The temperature works (It's much lower without R41) but it's still limiting the power, so I'll flash it with the 1200 fw.

Edit2: I can't find the jabe 1200 fw anywhere in this thead?

Thanks!  :)
Are these eeproms ok for it?
I attach my Eprom readout (2 files). You can try that.
I would start with the ATMLH028_AT24C256_readout_Jabe_UD-1200_20230924-T56.BIN

@DavidAlfa Please first try with your original Eeprom and show the results.
If that fails, then try the content from my file you mentioned in your last post.

Good luck.

Hey, your EEPROM dumps are wrong, it's a 24C08, not 24c256, can be clearly seen in the original pictures.

@DavidAlfa You're right. The ATMLH028 08CM is a 24C08C
Filesize should be 1k not 32k (00000000 to 000003F0). I can't remember how i did that mistake. In my notes, i onced wrote 24C256C.
I have 2 1k files from early last year. I will read the eeproms later this day again.

The 24C256 uses 2 bytes for addressing, the 24c08 only one, thus reading the 08 as a 256 will lead to bad data for sure.

Otherwise, reading a small chip as a larger model (Both with same addressing mode) will rollover and repeat the data, but give good data after all.

@DavidAlfa Here is the readout from UD-1200 Eeprom. I did it with the RT809H programmer because the 24C08C was listed in the supported chip db. The Batronix BX48 II and the T56 only have 24C08, 24C08A or 24C08B. I don't know if that makes any different. The data looks like the same i read before. So i guess there is only variable temp setting or somthing stored on the eeprom.

Thanks! :-+
As far as I know there's no difference in protocol or capacity, maybe lower power consumption, faster speed, different working voltage, temperature range...

The data looks pretty different from these dumps...

I noticed that the station randomly booted in chinese and english when using the wrong EEPROM , so definitely the languages can be changed somehow.
With your last dump it's always in chinese?

My UD-1200 has an english menu.

The solution: just erase the eeprom, it'll load the default settings and boot in English.
It only holds the menu settings.

Your last eeprom dump seems wrong too?
Mine starts with "AA 55" (Also did the UD1200 after erasing the EEPROM) , yours is missing the first byte and lacking the last one in the data block.
If you group the data in 2 bytes you'll see they're 16-bit integers containing the menu data,  max power, max temp, etc.

There's a newer UD-1200 with v3.02.02 firmware, it's the same thing but adds fast temperature switching/presets.

The 210s have much newer fw, I wonder if I can overcome the power limit by modifying the fw.

Also, I tried modifying the EEPROM data.
Power limit is byte at 0x0B, it's set to 0x1E(30 decimal) in 210 stations and 0x83(130 decimal) in 245 ones.

Setting this byte to 0x82 in 210 fw effectively unlocks all the power!
There's a catch, if you lower the power in the menu or perform a factory reset you'll lose it.

I'll try to patch the firmware to unlock the power!
This 210 has 2022/06/23 SD-v3.02.04 fw.

Did your 1200 pro and non-pro came with the same fw version?
If so, it should very easy to perform a diff of them and see the differences!

@DavidAlfa Does the T245 handle work with full heat now?

Yes (But needs R41 obviously)
