Did you maybe accidentally measure voltage instead of resistance? Pretty sure most of the diagnostic procedures involving B135 with a value of 1 are for resistance, not voltage. I highly doubt the donor ECM would be having a problem in the same exact circuit. There are 5 different o2 sensor codes relating to the heater circuits - P0030, 31, 32, 37, and 38. When I was having my issue, it would randomly throw 30 through 32, and it was fixed immediately after swapping the ECM. It's been running fine ever since. I don't think the donor ECM would show the same exact code out of the 5 possible codes. I would double check that you thoroughly checked everything in the diagnostic procedures for all 5 codes, and make sure all the wiring and connectors are in good shape. Have you also tried a new sensor? Was it OEM Denso? Good luck, with some patience and diligence, you'll get it!

I know this is an old thread, but I figured I'd post what worked for me since it took me like 2 weeks to figure this out. I could never get Ryan Geyer's method to work for my 2012 Forester because it's for an older chipset. The bin files would never show the VIN on them. My car has a 93c86 chip labelled "IC402" on the board. I guess this chip stores more data than the ones mentioned in the guides, which were used in earlier years. I followed this video and it ended up working out for me. I just successfully cloned my ECM to a donor and the car started right up. I bought a CH341A USB MinProgrammer (Black Edition) from Amazon, and the same 8pin clip mentioned on OP. The software is in the YouTube description. I had to do the read and writes with 16bit selected, because 8 bit didn't produce the VINs. For 16 bit configuration, wire 6 on the eeprom clip has to go to terminal 8 on the CH341A. Good luck and I hope someone out there finds this helpful! https://www.youtube.com/watch?v=hPKckby54uA
