Recently I bought Meizu Pro 5 with an international firmware, but I cant update the Flyme OS (currently I am using 5.1.6 but I saw that the latest version is 5.1.10 . When trying to upgrade a ‘Firmware corrupt’ error shows and whatever I’ve tried it cant upgrade.
Also I am trying to unlock the bootloader in order to put TPWM recovery to be able to backup the OS and restore it in case it crashes (bootloops) because I am willing to delete some system apps. Tried with ‘fastboot oem unlock’ it says ‘OK’ but after reboot in fastboot it shows me again that its locked.
Thanks guys in advance,
That’s a pending question in the forum.
Until meizu releases a flash tool, or meizu certificates, you will not be able to unlock the bootloader.
If you meizu model is “rooteable” you can try fiddling around with flashfire, but be very careful … you may hardbrick your meizu. And again, without meizu flash tool or their certificates, you will be stuck with a brick !
@addicted2sex To update the device if it’s an international version you should use G version if you get corrupt firmware the reason is that your device is a false international and you should use A version or install G version by converting the system there is a big thread about it
@Kikounet95 As far as I read in the forums:
- I need to downgrade first to 5.1.3A (https://forum.meizufans.eu/topic/6086/how-to-installing-custom-roms-on-the-pro-5) to be able to unlock the bootloader;
- Upgrade to 5.1.10G (https://forum.meizufans.eu/topic/2599/guide-how-to-install-i-international-firmware-on-your-chinese-mainland-meizu)
- Install TWRP (https://forum.meizufans.eu/topic/6086/how-to-installing-custom-roms-on-the-pro-5)
Correct me if I am wrong
@Kikounet95 You there ? I am having problems with changing the region ID. Installed the exact same version of busybox as described, executed the commands in the terminal, when I ‘cat’ the proinfo file its intl_official, but when I restart the phone its again mobile_public ? What to do now ? :(
Edit: Successfully unlocked the bootloader, installed TWRP and upgraded to 5.1.10G.
The only problem that left is the battery drain. My battery drops 20% for 2 hours ? :/ Any suggestions why is that (thats without wifi on, mobile data on and the brightness it set to almost minimum) ?
