NOTICE AND WARNING - RISKY; HIGH POTENTIAL FOR HARD BRICK USING QPST

Even though I haven't been able to succeed in my original idea yet - https://together.jolla.com/question/186437/enable-other-3g-bands/ - I thought someone else, (who actually knows what they're doing), might appreciate it, and maybe increase my chances...

Needed: * Windows, (I used Win10 64-bit, but probably any) * Developer mode enabled * Files: https://mega.nz/#!IN4lnZwQ!8oK_dljNq819x6_THDBrqnmPmcTx2XLl_ZmVPx0z_r8 * Disable driver signing in Windows, (look it up for your version; not hard)

1) Extract files, (and install QPST, if you plan on using it) 2) Follow this guide - https://blog.peremen.name/entry/enabling-qualcomm-diagnostic-mode-on-jolla/ - to add diag mode capabilities 3) Restart phone and pc 4) Connect phone in with developer mode enabled. You should get a new device pop up in device manager, called "Jolla", or "Xperia X", with a yellow exclamation mark. Right-click, "update driver", "browse computer", "let me pick", "show all devices", "have disk". Navigate to the folder you extracted, and go to /OPO diagnostics driver/(whatever version)/...ini file. Click 'Ok', and 'yes' to any warnings/confirmations. Driver should install, and "Jolla" will change to "HTC Modem" in device manager. Right-click, and select 'properties', and you'll see port number, (COMx), which can be used to access modem.

Works for me...
