Hi Laurent, you're 'da man' for me, if you managed to root this weird and unpopular iPlay20 Pro! Just got mine a few days ago, start regretting this purchase of another 'oddball' device. I am not impressed by the Android 10 implementation and limitations, need root access badly to gain control over its weird behavior. My tablet came with T1011S_V1.0_20201208 , a firmware file I cannot locate ANYWHERE. It did want to 'update' after firing it up, but I did not allow this for now, 'rooting' my options first. AlldoCube does not reply to my questions and FW file request - poor service. My goal is to somehow find a way to unlock the bootloader (many say that it is very hard for this specific model) and use Magisk's binary fix. I did this for another odd Android 9 smartphone (Cubot) before, hair raising but eventually successful. I started collecting iPlay 20 specific infos, software tools like SPD_Upgrade_Tool, SPRD_NPI_USB_Driver etc.. Would you be so kind and walk me through YOUR way of rooting the iPlay20 Pro without bricking it? Apparently this process really needs the EXACT firmware level files, one cannot 'steal' them from the iPlay 20 (no Pro) or earlier/later revisions? I opened a new generic topic "iPlay 20 Pro" in the parallel product discussion forum. Maybe we can bundle our forces and experiences over there, for the benefit of all owners and users? Thanks for any useful hint!
