清除数据再升级一次

Im sorry i dont know Chinese my friend, can you write it in English please?

Ok i translated it, "Clear the data and upgrade it again". I clear the data, but i cant update it again! i update with the terminal emulator method, i cant with other way, because i put the global version but my phone is Chinese version. So i did with the terminal emulator, an the busybox method. But now i dont have busybox and terminal emulator, becasue i clear my data, and i cant download them because the divice does not allow me.

Chinese version？Are you sure？
Which version is your mobile phone running now?G or A？

now is running G version. But i make a procedure to do that. I bought my phone from china and when i bought it was A verion, but i live in europe so i needed the G version. So when a new update came to my device, an di installed it it was the new A version. I went to flyme website to download the G version, put it to my storage, try to run it but i got the message FIRMWARE CORUPT. I search for it, and i found out that this is beacaus eit is a A version so i cant put the G. One day i found a guide how to install the G version to a Chinese one. i followed that and i successfully made it. And this is the procedure with the busyboix and the reminal i told u. I will post that method below soo u can see. And this is now the only way that i can update my phone. OTA does now work, i dont get anymore notifications when a new flyme update released. I made a lot of updates with this method, around 3-4 so im sure that it works, and it is official, from flyme forum. Also worked to flme 6, everything is fine except those problems i told u. And now i cant find a way to go back to 5 flyme


METHOD 2: INSTALLATION THROUGH THE TERMINAL
1. Enable root

Enable root by tapping on Settings-> Accounts-> My Flyme-> Personal settings (first option) -> System privileges and set it to open - accept disclaimer and confirm.
2. Download and successfully install Busybox (from Google Play or see .apk below)

3. Download and install a Terminal Emulator (from Google Play or see apk below)

4. Download the correct and desired international (i) ROM/firmware (update.zip) for your device

5. Download and use the update.zip (firmware) converter that creates the required system-i.img

Click here to download converter first
Copy system.new.dat and system.transfer.list (from the update.zip) to the folder “in” (see converter folder)
Then start the converting process by starting System-conVERTER.cmd and pressing option 1 [enter]
If successfully converted you can find the system-i.img in the ‘‘out’’ folder.
6. Copy the converted system-img from ‘‘out’’ to the internal memory of your Meizu device

7. Go to Settings-> Display-> Sleep and set it to at least 10 minutes

8. Start the Terminal Emulator and run (type) the super user command

su
A permission popup will come; give permission by tapping allow (always allow).
9. Now run (type) the command for installing the system-img.

dd if=/sdcard/system.img of=/dev/block/platform/XXXXXXX/by-name/system
Replace XXXXXXX with the correct partition system for your device
MX4 Pro = 15540000.dwmmc0
M2 note = mtk-msdc.0
MX4 = mtk-msdc.0 (OR mmcblk0p6)
MX5 = mtk-msdc.0 (OR mmcblk0p18)
Pro 5 = 15570000.ufs
Example for MX5 : dd if=/sdcard/system.img of=/dev/block/platform/mtk-msdc.0/by-name/system
Note: Pro5 might require: dd if=/storage/emulated/0/system.img instead of /sdcard/

10. The installation should start after the ‘‘dd if’’ command, but please note…

…it may seem that the copying/process did NOT start because you didn’t notice it, but it DID start.
do NOT type a new command or whatsoever, just…
…be patient and give your device 5-10 minutes to process.
11. When the process is done you’ll see a # at the very end

Your device should be unresponsive by now - this is normal
12. Now just shutdown your phone (hold power button) and reboot it

13. Once successfully booted your device should be running an I-rom

Once in Flyme again it is wise - but not necessary - to completely reset your phone. Go to settings->about phone->memory->factory data reset-> check both boxes and click start cleaning (this could take 5-10minutes). Always backup your stuff if necessary.
END OF METHOD 2

My MX5 is Chinese version。
Last year, I tried to update to G version (an easy way) and was successful.
And then back to the A version, everything is normal.

So I suggest that you can try to downgrade to Flyme 5 G version

Can you resume the factory?
If it works, you can try downgrade to Flyme 5 G version,and must clear the data.

how can i downgrade it now? i cant put anything to the memory of the phone from computer, even i cant download anything from the device's browser. How i will downgrade it?

what you mean to resume the factory? I made a factory reset if you mean that, i just wipe everything except my files, because i need my files i dont want to remove them. Also im not sure that its going to work if i factory reset it wiping also my files. for now i cant put the flyme 5 to my phone how im going to downgrade it?
