I'm one of those that had a new ECU (811) and a reflash.
1st CEL: they replaced my ECU with the new one (811). No flash.
2nd CEL: they flashed my ECU with the latest update
My car threw a 3rd CEL when the technician was driving my car around the block, after the flash was done. So, in my case, the 811 ECU and flash didn't fix my problem. Toyota told my dealer to order a new ECU (supposedly newer than the 811 I had installed).
