I tell my problem with the Meizu MX4, first of all I say that I do not understand anything mobile, root, and I am very careful not to touch anything mobile. I bought it in Aliexpress, in November 2014 by the good reviews it had received and smoothly
I’ve been working ok until August 2015 with the same firmware that came, the issue is that the mobile started to do weird stuff, being on a table without using sounded as if the camera did photos, so look as updating and I upgraded from the mobile application, starting to download a new firmware and when he had copied nearly 400 Mb, skip the message corrupt firmware, there began my ordeal, since it is in a bootlop mode.
The meizu that I have is the M460, the problem is that when i try to upgrade, don´t see what firmware version I had installed, I download several versions of all firmware, A, I, C, U, even the Y, the oldest and the newest and nothing, whenever I go into recovery mode with vol + and power, I enter the update.zip and give update with and without clear data, I get the same message, FIRMWARE CORRUPT. If I press vol - and I get power in FASTBOOT bottom of the screen, but do not go there.
I don´t know what to do, because I have tried all the firmwares that I said, my last option is the specialized forums to see if anyone helps me.
I would avoid sending it to China, since the store where you buy apparently no longer works with Meizu and not know how to apply the guarantee, I have fear of never seeing the Meizu,
