my main goal is to have OREO on this beautiful cdma gsm htc 10 Sprint variant, let me tell you what i have done until now.

1. i went to this post and checked all my options: https://xdaforums.com/sprint-htc-10/development/ruu-sprint-htc-10-1-24-651-3-t3379257.

2. i downloaded the very first exe showed there, which is Sprint_HTC10_3.18.651.3_RUU. i executed it but failed with an infamous 132 signature error. i read about but didn't find a solution.

3. i decided to leave any exe for the noobs, so i downloaded my exact ruu.zip, which is 2PS6IMG_2.42.651.6_RUU.zip. actually my firmware is 2.42.651.66, with and extra 6; anyway, it failed too but this time with this message on PowerShell:

PS C:\zzzTuco153\HTC path\HTC10> fastboot flash zip firmware.zip

target reported max download size of 1579200000 bytes

Invalid sparse file format at header magi

4. i moved on and downloaded this 105.1mb firmware: 2PS6IMG_Sprint_2.42.651.6_signed_firmware.zp. i flashed it twice:

5. i was happy, now something flashed correctly so i flashed the 2PS6IMG_2.42.651.6_RUU.zip ruu again and guess what...

PS C:\zzzTuco153\HTC path\HTC10> fastboot flash zip ruu.zip

target reported max download size of 1579200000 bytes

Invalid sparse file format at header magi

6. i didn't give up, so i downloaded the 100mb firmware 2PS6IMG_Sprint_3.18.651.3_signed_firmware.zip for oreo and did all the same with the ruu for oreo, same result....

7. i noticed this https://xdaforums.com/showpost.php?p=67056758&postcount=4, so i proved Sneaky's fastboot. this time the previous steps became into this
