If anybody can modify for my this file (see first post) and change both final 0 of version numbers to 2 (see #6 post, TPM20_5.62.3126.0_to_TPM12_4.43.258.0 ----->TPM20_5.62.3126.2_to_TPM12_4.43.258.2) and give back to me modified and with checksum corrected (to avoid flasher "corrupt file" error) I will thank you! 
I’m not able to do it…
