Does it really Aliexpress/Ebay do not send parcels to your country?
It fact, real problem is that morden X-40 laser tape measures have a newer module "M88B" which is not supported by my firmware.
What type of the programmer you are using?
How do you connect the NRST line?
I can see that module is really 703A.
If you have an oscilloscope, you can check reference signal at TP1 - https://raw.githubusercontent.com/iliasam/Laser_tape_reverse_engineering/master/PCB_photos/module_701A/PCB_top.jpg
