Good, we have taken this variant, but the method works with the other variants of this Huawei model, but with its correct firmware and compilation.
In the link that I leave, there is everything, step 1, step 2 and there is rar with the instructions, it is tested 100% with smart clip 2 box that is what I have, I do not know if with the other tools it will let it do, I do not I know, I mean, HCU, eft dongle, etc., as I have seen on the internet if it can be done with all of them, but I don't know, so you have to try.
