METHOD 1: INSTALLATION THROUGH ADB VIA PC第一种方法：连接通过电脑刷/thread-23842-1-1.html旅游无疆界 hb1987628–Required before using ADB command to install.1. Rooted device (note: you need a Flyme account for this).一：先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. Busybox (SuperSU should be possible too) installed.*二：安装busybox•You can download and install busybox from Google Play (or search for the .apk file yourself).Note: make sure it is installed successfully.3. Setting up phone3：安装ADB驱动！（连接过电脑的可以忽略）• 3.1Set your device on ‘connect as Built-in CD-ROM’ (settings->about phone->storage->connect as).• 3.2Connect the phone to your PC and copy the ‘‘USB Drivers’’ folder from your phone to your desktop.• 3.3 Go to settings->accessibility->developer options and enable ‘‘debugging’’ and mock locations.4. Install ADB drivers四：无视• 4.1 Open Windows Device Management (search:devmgmt.msc). You’ll see a yellow exclamation mark at‘‘Androidphone/ADB interface’’ - right click on it and clickupdate driver. Click browse my computer for driver software(2nd option) and then click on browse and locate the driverfolder you copied from your Meizu phone to your computer (atstep 3.2). If it installs your good to go to pre-install if not go tostep 4.2.• 4.2 [Optional] When trying to manually install the drivers Windows could give a error l ike ‘‘the driver is corrupt or hasbeen tampered’’ If this is the case you’ll need to Disable Driver Signature Verification.How to: (1) Hold down the SHIFT key while you click Restart.(2) Once rebooted click the Troubleshoot option. (3) ClickAdvanced options. (4) Click Startup Settings. (5) Click Restart.(6) Now Disable ‘‘driver signature enforcement’’ by pressing F7(7th option in the list). (7) Now you’ll be able to install the driver - at step 4.1 - without an error..前面是准备工作！基本就是root和安装busybox-Now you can start the pre- installation procedure1.下载ADB文件夹 /s/1kT5uT1P1. Download ADB (files) folder click to download ADB files•Download (see link above) and unzip the folder.2. Setting up .android folder2设置.android文件夹如下图！新建adb_usb.ini 里面的内容为0x2a45，注意后缀名为ini•Go to ‘‘c:\Users\your name\android’’ and create or edit the ‘‘adb_usb.ini’’ file in this folder. Create it by making a txt file and name it to adb_usb.ini (don’t forget to replace .txt by .ini). Open the adb_usb.ini file with notepad for example and add thefollowing text in it: 0x2a45Note: If there is no .android folder, run the commands in step 3 and search again, also check ADB-drivers.3. Checking driver and connection3.现在检查驱动和连接，打开文件夹！打开运行打开cmd运行框后输入adb kill-server然后回车（Enter键，键盘里最大的键）然后再输入adb devices回车，如图•Start ADB shell by clicking the .bat file in the downloaded and unzipped adb folder. (运行 means run)•In the just started ADB shell run (type) the following 2 commands:adb kill-serveradb devicesAfter the 2 commands mentioned above you should see your device below ‘‘list of devices attached’’.Note: [Important] If the device list is empty it does not recognize your device and you should check: if you installed your drivers correctly, if the .android file exists and if it contains the adb_usb.ini file with0x2a45 in it. If you sure you did - try rebooting your PC or kill the adb.exe process - and connect/reconnect your device again - and run (type) the command again. If you’re getting a ''Permission denied" error make sure you have busybox or SU correctly installed and that you did all the other required steps (root, debugging,mock)..-The Installation through ADB这里的123步都是制作提取国际版固件！就不做解释！我直接发我提取的/s/1bn8ZcVt国际版455i 大小为1.28G.1. Download the correct and desired international (i)ROM/firmware (update.zip) for your device•Download from /en/firmware.html or•Download from: http://downloads.meizufans.eu/2. Now download and use the update.zip (firmware) converter that creates the required system-i.img•Click to download converter and unpack theConverter_system_Lollipop folder to your PC.•Copy the files ‘‘system.new.dat’’ and system.transfer.list fr om the update.zip to the ‘‘in’’ folder of converter.•If you copied the two above files to ‘‘in’’ start the process by clicking on System-conVERTER.cmd•When completed you should have the required image in the ‘‘out’’ (you’ll need it for updating).4. Now copy the created image from the ‘‘out’’ folder to the root of your device.把从百度云下载的或自己提取的系统system.img 放在手机的根目录•Copy it to internal system memory of your device5.Open ADB by clicking the (运行) run.bat file in the ADB folder and type the following 3 commands.现在又回到刚才的cmd框！关掉的话直接打开就行！•输入adb shell 回车•su 回车•dd if=/sdcard/system.img of=/dev/block/platform/ mtk-msdc.0/by-name/system 回车•如图•adb shell•su•dd if=/sdcard/system.img of=/dev/block/platform/XXXXXXX/by-name/systemIMPORTANT: Replace **XXXXXXX **with the correct partition system for your deviceMX4 Pro = 15540000.dwmmc0M2 note = mtk-msdc.0MX4 = mtk-msdc.0 (OR mmcblk0p6)MX5 = mtk-msdc.0 (OR mmcblk0p18)So for the MX4, for example, your command will be:dd if=/sdcard/system.img of=/dev/block/platform/mtk-msdc.0/by-name/system这里只有说一点~就是最后的那个命令行如果是PRO5的话应为dd if=/sdcard/system.img of=/dev/block/platform/15570000.ufs/by-name/systemNote:After giving the ‘‘su’’ command your smartphone may ask for confirmation tap allow/confirm on your screen.输完dd if 那一行后看似手机什么都没搞！（如果卡顿也是正常）大约5分钟左右出现“#”就说明已经成功了，好，现在重启手机，手机会出现优化程序，大功告成！6. The installation command will take some time (± 5min)•After it is done you’ll see some records in and out and at the very end the following sign: ‘#’;. If this is the case it is done.总结：最好是先刷455A版本最简洁步骤就是，1 root2安装busybox3把system.img放在手机根目录，4输入三行命令，好结束祝大家都成功7.Your phone should be updated by now, but your device will be unresponsive, this is normal.•Hold the power button for 5-10 seconds to shut it down. Now start it up again and wait for it to update apps etc. and yourphone has updated successfully. However, once in Flymeagain it is wise - but not*necessary - to completely reset yourphone. Go to settings->about phone->memory->factory datareset-> check both boxes and click start cleaning (this couldtake 5-10minutes [Note: this deletes everything!!!]Note: if the booting - after flashing/updating - takes longer than 15 minutes go to recovery and factory reset it and try again (boot with volume down button + power button to access recovery).END OF METHOD 1METHOD 2: INSTALLATION THROUGH THE TERMINAL第二种方法就不介绍了自己看看吧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.

Copy the converted system-img from ‘‘out’’ to the internal memory of your Meizu device7 Go to Settings-> Display-> Sleep and set it to at least 10 minutes8. 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 deviceMX4 Pro = 15540000.dwmmc0M2 note = mtk-msdc.0MX4 = mtk-msdc.0 (OR mmcblk0p6)MX5 = mtk-msdc.0 (OR mmcblk0p18)Example Mx5 : dd if=/sdcard/system.imgof=/dev/block/platform/mtk-msdc.0/by-name/system10. 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 normal12 Now just shutdown your phone (hold power button) and reboot it13Once 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.
