This seems to match your observation " the symptom was that the card did not send R-APDU at all and just died ". It is used for storing persistent data. In this case, operate the TV after first turning off the power, or unplugging the AC cord and re-plugging it in after one or … Electronically Erasable ROM is a type of memory available on most boards.

Check if you pressed ''power'' on the TV. Put the EEPROM in a reader and try to read it, save the file - then repeat those 2 steps and compare the files, if they differ, its a flaky EEPROM. It is more deep “reset” than the reset from menu or from hidden service menu. They erased the EEPROM. You can find UFI SPI service Pinout by click on the chip icon Now you can direct soldering to UFI Service Pinout with wire. If they differ - you could try several attempts to read, blow the code into new chips and see whether any of them work. The TV cannot be operated. When working with EEPROM I'm working on developing methods to expand the life of the EEPROM as long as possible but also checking it for corruption and doing everything I can to avoid corruption upon several occurrences that may happen on a daily basis such as power failure. hi!!!
