In the new year, I had to bid farewell to the old and welcome the new, so I got a Lenovo ZUK Z2 replaced by my family.This mobile phone, released in May 2016, has a flagship Snapdragon 820 processor, which is equipped with a customized ZUI 2.0 system based on Android 6.0. With a 3500 mAh battery and a relatively low price, the price of 820 chips has been raised to 2000 yuan.Like Xiaomi Mobile Phone 5 released that year, ZUK2 has won the favor of a large number of young people once it was released. Zuk is a sub brand of Lenovo, which is Lenovo's turnaround in the mobile phone industry.Zuk is called "free guest" in Chinese, so as to win the love of young people. Unfortunately, he failed to turn over and was pushed back by Xiaomi.However, the ZUK series (including other Lenovo mobile phones) declined, and the CEO of ZUK often changed his job to Xiaomi, which was the last word.
I really like the minimalist design of Z2. There is no logo on the front, 1080p resolution, 70.63% screen share, and 13 million rear camera.My rear camera is scrapped, unable to focus, and the picture is blurred.In addition, the lower right corner of the back cover is smashed, which makes it difficult to be a second-hand mobile phone.Fortunately, the screen is intact, and there are no obvious scratches on the front. It's good to use it to brush the machine
Although ZUK Z2 was four years agomobile phoneThe official system only supports ZUI 4.0 developed based on Android 8.0, but thanks to Google'sProject TrebleThe project, as well as the attention paid by domestic and foreign developers to ZUK, enables Z2 to have a stepmother who is closer to her mother - a strong system ecological environment. Even if half of her body has been buried in the loess, she can also enjoy the original Android Q and the upcoming Android R.

2. Unlock
1. Install the drive
In general, when connecting the computer for the first time, ZUK Z2 will prompt "Run ZUK_UsbDriver" to install the driver.Click Run to install by default.
Connecting the PC

2. Start unlocking
Because we need to use adb and fastboot to establish connection with the phone and operate the phone, we need to install adb suite platform tools.You can goSDK tool platformDownload the corresponding computer suite, or get a backup at the end of the article.After the download is completed, decompress it directly and use it.
You can download the attachment in the emailunlock_bootloader.imgSave it to the computer. It is recommended to move it to the platform tools folder to facilitate subsequent operations.
Connect the mobile phone to the computer, open the unzipped platform tools, press and hold Shift+the right mouse button, and select "Open Powershell window here".
Open powershell
input
adb devicesor.\adb devices
At this time, the phone will prompt words like "Allow USB debugging?", tick "Allow debugging with this computer", and confirm.The following display indicates that the connection is normal.
Re enter
adb reboot bootloader
If the prompt is invalid, you can add it before.\
.\adb reboot bootloader
If there is the same error later, please press this input and do not prompt again.
After the command is executed correctly, the phone will restart to the fastboot mode, and the following information can be seen on the phone screen:
FASTBOOT MODEPress volume key to select, and press power key to selectFASTBOOT MODEPRODUCT_NAME - MSM8996VARIANT - MTP eMMCBOOTLOADER VERSION -BASEBAND VERSION -SERIAL NUMBER - 2d8b7c81SECURE BOOT - enabledDEVICE STATE - locked
Enter the following command to start unlocking. If you do not want to continue unlocking, press the volume key to select Restart, and press the power key to confirm to restart the phone and exit the fastboot mode.Once the implementation is successful, the warranty will disappear.(But there are no Zuk mobile phones available now.)

If the connection between the phone and the computer is normal, the following prompt will appear.

After the command is executed correctly, the interface content remains unchanged. For Z2, Z2 Pro and Z2 Edge phonesbootloader.imgIt has been burned to the mobile phone, but it has not yet taken effect. It needs to be executedfastboot oem unlockAfter the command, pressVolume keys up and downchoiceYESAfter that, press the power key to confirm to continue, the phone will restart and erase the user data, and the unlocking is successful.The content of that interface is roughly as follows:
Unlock bootloader?It you unlock the bootloader, you w111 be able to install custom operating system on this phone.A custom os is not subject to the same testing as the original os, and can cause yourphone and installed applications to stop working properly.To prevent unauthorized access to your personal data, unlocking the bootloader wil1 also delete all personal data from your phone(a "factory data reset").Press the volume Up/Down buttons to selectYes or No. Then press the Power button to continue.YesUnlock bootloader (may void warranty)NoDo not unlock bootloader and restart phone
If you want to confirm whether it has been unlocked, simply switch the phone back to the fastboot mode, and a message similar to the following will appear, indicating that the unlocking is successful.

Brush in TWRP
After unlocking, the third party Recovery can be used to clean the machine happily.The Chinese TWRP produced by wzsx150 is used here, which is attached with a one button brush in tool. Follow the prompts.
Brush in third-party ROM
ZUK Z2 enters Recovery mode in a special way.After unlocking, restarting the phone will add a screen to remind you that it has been unlocked, which is roughly as follows:
start >Continue boot< More optionspress VOLUME keysYour device software can't bechecked for corruption. Please lock the bootloaderVisit this link on another device:g.co/ABHIf no key pressed:Your device will boot in 5 seconds
Press nowVolume UpEnter the startup menu, which is roughly as follows:
Options menu:Press volume key to select, and press power key to selectpower offRestartRecoveryFastbootBack to previous page
PressVolume up and downchoiceRecovery, press the power on key again to confirm, and then restart to enter Recovery.
The interface of TWRP is too boring to introduce, and the method of machine brushing is also super simple.Refer to other brushing hydrology such asXiaomi 6、Samsung S9+Procedure for using TWRP brush.Because I hate trouble, I painted PE 10 modified by Ku'an Big Brother.
experience
The modified system has made gesture adaptation to the entity home key of Z2, which is not bad.But the bad thing is the battery, which has been used for three or four years. No matter how much you cherish it, the battery has aged.This one in my hand is even worse. The power is dropping alarmingly. There is no sign of automatic shutdown, and it can not be used normally.It is a good choice to use it as a standby machine charged with electricity.But the tests in the past few days have found that it is really strange for a mobile phone to be able to be put on standby for several days.
Brush in LineageOS
In 2023, three years later, I found this ZUK Z2 in the drawer.After a simple search, there is even official system support!In short, try painting one.
Then, restart to Recovery and directly import the ROM package!It's that simple!It can be directly brushed in without the official hot chicken REC!
If you need to use GApps, I have a backup file here:Portal。
If you want to install Magisk, I also have a backup herePortal。
Since Magisk26.3 cannot be directly imported in TWRP, you need to back up BOOT.img in TWRP first.Then use Magisk to patch the backup BOOT.img, and use TWRP to overwrite the BOOT.If you import the ROM package I backed up, here are the packaged boot files:Portal。

After playing for a while, the main part of the mobile phone is the CPU. It used to be OK, but now it is not suitable for playing games, and it is easy to get hot.I always use the lowest version of the bony bag. The screen is small. It is estimated that there is no such small phone now. At that time, the 5.5 screen was the mainstream. This phone can be so small and easy to carry.If you don't play games, it is very suitable to be a standby machine.It also supports fast charging.Check out the video.Listening to music is very good
Wuwuwuwumy main force Pixel can't brush many systems because the system partition is too small, a littleCan only cloud brush the machine (watch others brush it)
Speaking of battery life, the biggest weakness of mobile phones is the battery.Higher and higher frequency of use+large screen+5G, even if the chip technology has been improving, it can not stop the demand for power.Fortunately, the power of fast charging is getting higher and higher, saving the poor endurance of mobile phones from another direction.
I feel nostalgic when I see the Android machine cleaning I remember that my first smart machine was the Samsung S2. At that time, domestic machine fronts, foreign XDA and CM forums paid high attention to this machine, which made the impression of this 11 year machine finally brush to Android 6.However, with the increasing integration of mobile phones, manufacturers are basically reluctant to open the bootloader, and CM has also disbanded (tears of the times)
Although CM was disbanded, it established a new community calledLineageOS。Compared with the ecology ten years ago, today's third-party ROMs are much more prosperous.In addition to Los, there are many native ROMs, such as the Pixel Experience most like Google Pixel. BL is more difficult to understand than before, but as far as I know, Huawei has refused to unlock bl, so I will not buy Huawei!An Android machine that cannot be cleaned has no soul! By the way, I have had a mobile phone since 11 years ago, but it's still Samsung's S series... I cried
Wow, CM is still here Say that I changed the NEX a year and a half ago, but now I can't understand itIt is said that most of the machines in the Blue Green Factory (the main blue factory) cannot be unlocked. I always thought that the next machine must be replaced by a fully open one like Yijia. Later, I gradually used less mobile phones (mainly mobile games are not played), which are basically used to respond to messages, watch news RSS, play Twitter, listen to music and watch videos. The impulse to change the machine gradually decreased.It seems that the 845 is still very strong. Maybe the NEX will last for two or three years. If I want to change the phone in the future, I may prefer a small screen phone now.Now the mobile phone can't move 6 inches, and the pocket can't be stuffed
I forgot to say that the mobile phone of the Blue and Green Factory is also determined not to buy. The system is too similar to IOS. Now the big screen is the trend, and the small screen is also made by Apple and Sony. You can pick up Sony's small screen phones, which are not cheap, but beautiful
LOS has the advantages of fast publishing and multiple adaptations.I used to brush the LOS and taste the Pie directly because the MIUI was too bloated (at that time, MIUI10 was still skinned, and it was always Android 8.0).However, the quasi native system is too unfriendly to domestic machines. If the fingerprint is not signed, you can only use JD to pay. Gapps has lost a lot of convenience even if it is not connected. It was replaced two or three months later.
I don't think LOS is hard to use at all, but MIUI11 is full of functions. The latest internal test even has a small white bar.I don't want to use native anymore. MIUI really smells good!
