Having the same error. After flashing the Azarton MHO-C401 the display is frozen/stuck. I get readings but the display won't update. Also, a reflash to the original/custom firmware doesn't solve it.
Any ideas or updates on this?
@Rocket200 I tried again to reflash but without success. Could a picture of the PCB help? Maybe it is a newer revision? Different GPIO pin or something?
this new CFW fix it ? MHO_C401_v33.bin

but same Display not working Freez the Old Temp. ...
Xiaomi Miaomiaoce MHO-C401 has a different E-ink display and different PCB.
all working fine … with your FW only the Display is freezing and not show the correct Temp.
Azarton:
Well I should have read this first but I've flashed the Firmware to my Azarton-MHO-C401 and have the freeze, too. The readings work fine but having the Display back would be an enhancement :-) The Custom-FW doesn't work because we have a different PCB and Display and that's the Problem for the Recovery FW as it's not from the Azarton Device. @pvvx Is there a way to make a backup from a working Azarton-MHO-C401 and flashing that back to the broken one, or is there a way to fix the issue with your Custom FW?
Make a Flash backup of a running Azarton-MHO-C401
- Using TelinkMiFlasher.html download 'BLE-Hacker.bin'
- Using TLSR825xOTA_Hacker.html, connect to the appeared device "BLE_xxxxxx"
- Restore original firmware boot: "Change Start Boot" key. (Do it once!)
- Read All Flash to File: "Read Full Flash" and "Save to File".
- Close 'TLSR825xOTA_Hacker.html'.
Share FullFlash.bin in the public domain. I will cut OTA_xxx.bin out of it.

Ok sounds like a plan for the weekend :-) Just to be sure... the working one will boot the orginal firmware again after step 5?
Ah great, I installed the custom FW on my Azarton MHO-C401 today and also have the frozen screen. Fow now I don't have a working one to download the firmware, I'd appreciate if you could upload the original firmware.
P.S. it is the same version posted earlier:
the working one will boot the orginal firmware again after step 5?
Yes. Using the "Change Start Boot" option also sets the reboot flag after disconnect. The main thing is to read FullFlash and make OTA.bin...
@pvvx ok it seems like it worked and best of all it's still working :-) Attached is the FullFlash.bin Don't flash this as that's the one needed to make the actual real OTA.bin azarton_mho-c410_ff.bin.gz

@evildad Thank you for providing Full Flash! I checked the check-sum and firmware functionality on another module with TLSR825x. But I don’t have Azarton MHO-C401 and so far I can’t make support for new E-Ink.
@pvvx Thanks for providing the Firmware, I was able to unfreeze my mho-c401 too.

What do you need to implement the new e-ink?

Time and opportunity to buy a "Azarton MHO-C401". They are not in the sale available to me.
Another piece of information:
The FPC cable has HB0168 printed on it, which might or might not lead to the manufacturer of this e-ink display.
Does anyone know how to remove the display from the Case?
@pvvx is there a chance that you can proceed with this device? i just bought one and like it quite a lot; would love to get this flashed with a custom firmware and get some more of them.
for me these azarton devices are available on amazon; if this is true for you too i'd be happy to donate one or two to make it possible for you to free them for us! :smiley:
For me the display of the azarton looks quite similar to the one of MHO-C201 (https://github.com/jonathonlui/MHO-C201) Has anyone ever tried that code for the azarton?

Xiaomi Mijia MHO-C401 -> https://github.com/znanev/MHO-C401
OK, you're right FPC looks same like MHO-C401. I thought because of the'x' in the batterie symbol.
Azarton:
MHO-C201:
It did not occurred to me that it is not just rebranded xiaomi. Xiaomi BT ones with LCD are the best TH meters I used, I then bought MHO-C201 by accident and then found Azarton on local Amazon.
I guess for now the ones with LCD are a way to go for TH measuring devices and just think of it as displayless device or do you know about some alternative in EU?
