Btw., I've found that there's absolutely NO need to root this phone... NetGuard firewall does a fine job, in spite of it being -only- a VPN solution and having no detailed control, with the ad-supported version.
There's a (last!) updated, stock
(!), ROM, which is not
available as OTA. It's labeled as the "S230" version, going to attach that image; managed to flash it, after unlocking the bootloader through Developer options (OEM unlocking), using SP Flash Tool - for MTK, MediaTek, based devices.
As always, it's a shame that Lenovo doesn't provide the flash tool(s), or the actual ROM file from their servers. BEWARE, be very
careful, when flashing: there's no way to verify the file, no way to tell whether the ROM is "official", or not - other than to, perhaps, compare signatures with the consensus of what legit is, right? Heh.
Anyway, hang on... Posting this on mobile, it's gonna take a few edits to get everything squared! xD
