I have the 4100NEX. Cant get it to go into test mode. Ive extracted, from the dropbox .rar, the individual files on my flash drive and waited about 15 min. I can see the access light blink on my flash drive but its not booting up. Ive tried a 16GB, 4GB and 1GB drive. All formated to FAT32. Does anyone else got any advise to send my way. Thanks.
