Hi!
My friend is looking for an Android tablet that has an unlockable bootloader and also has a custom ROM. I’ve checked a lot and every one of them is problematic. Usual brands here are Samsung, Lenovo, Huawei, Honor, TCL, Xiaomi. Apparently Huawei and Honor is out of question since they don’t allow unlocking bootloader. TCL is new so no ROMs. Xiaomi seems possible but unlocking a Xiaomi device recently became even more pain.
Do you know a decent model from these brands? Preferably 10-12 inch screen.
There are some linux tablets which may be better if you want unlock. less apps but much more hackable.
Personally I would go that way, though my Nexus 7 is already handling that pretty well. But I don’t think my friend would want a Linux tablet. :)
