Last week I've bought the Huawei P20 Lite and it's a great phone - but like the most of you all I like a rooted phone and the guide provided in this forum works perfectly but... my Huawei P20 Lite must have an unlocked bootloader.
No problem, I've used the Huawei unlock password webpage on my previous phone (P9 Lite), eh.... right... like other user mentioned - it's down for unknown reasons and an alternative isn't possible. Believe me I've tried them all - even the chinese pages which are very hard to read if you're not born in that country
So, I've read about DC-Unlocker other users have used to succesfully to get the bootloader unlock code but even when following every known tutorial to use it correctly I got no luck on my Windows 10 PC for hours to connect the needed COM ports. Even the programmer of DC-Unlocker respons in a forum question the software will only work on the P20 Pro!? But, other users managed to get the code.... strange..
Finally I've managed to get the bootloader unlock code and I do want to share it for all other users having troubles connecting the phone to use DC-Unlocker. It's my first tutorial so please be patient if I'm not clear or missing something; if that's the case do respond.
This one is quite easy but you'll need some patience (a couple of days in my case). Send a message with a request using the offical Huawei website and the Contact Us option: https://consumer.huawei.com/en/contact-us/
I send a mail something like this:
Dear customer support,
I would like to receive an unlock bootloader code for my Huawei P20 Lite phone. I am aware I'll void my warranty but would like to get receive the code anyway.
I cannot say how long it exactly will take to get a respons. In my case it was arranged in a few days but don't know how quick the respons will be for any other user.
For anyone who cannot wait a couple of days (like me), here's an alternative which will cost about 4 to 5 euro's (credits) to get the code using DC-Unlocker.
- DC-Unlocker client which can be downloaded here: https://www.dc-unlocker.com/downloads
- Windows 7 or 8 (Windows 10 didn't work for me - but hey, you can always try )
Well, let's go:
- First connect your phone to the PC using the original USB cable.
- When drivers are installed a popup screen would appear to view the "HiSuite" drive. This is a created drive-letter which contains a HiSuite Software downloader. Click to open or use the Windows Explorer to browse to this virtual drive.
- Install the HiSuite software - this is important to get the correct drivers AND correct COM ports installed on your system. Skipping this step will result in non working DC Unlocker software.
- When all is done go to the settings in your phone and open: System -> About Phone and tap the Build-number line about 7 to 8 times. Most likely the phone will ask for a PIN to active the developers mode. This is the code you've setup to use your phone. If you're already have a "developers option" you can skip this step.
- Now click the "back" arrow once and select "Developer options".
- Tap OEM-Unlock to activate it (confirm if needed), scroll down and tap USB Debugging to turn it on.
- Your phone should ask permission to connect your PC (with some MAC address). Confirm it so the connection is approved. If that doesn't show up disconnect the USB cable and check if the USB debug mode is still active in the "Developer options". Than reconnect the cable to your PC.
Now we're ready to use the DC-Unlocker software to get our unlock code:
- First you need some credits and you can buy the using this link: https://www.dc-unlocker.com/buy
- Just fill in the the fields User-name, E-mail and Credits. Leave the "New user account" option selected if you are a new user.
- For the Credits you only need 4 of them. I, initially, bought 5 so I still have one left
- You'll receive a confirmation e-mail with a username and password. These are needed a bit later.
- Extract the DC-Unlocker client to a fold and start it by clicking dc-unlocker2client.exe using the Windows Explorer (or any other file manager). To be sure you can also right-click the file and start the program using Administrator credentials.
- Select in the right portion of the program the tab "Server" and enter the username and password you've received by mail. Check the "Remeber" box and click "Check login" to verify your account.
- Click in the left portion of the program the dropdown list below "Select manufacturer" and choose "Huawei phones".
- Leave the droplist "Select model" selected at "Auto detect (recommended)".
- Grab your phone and open your dialer to type this code: *#*#2846579#*#* - this will get you into the service menu of the phone.
- Tap 1. Background Settings -> USB Port Settings and select Manufacture Mode and than tap Close.
- Put the phone done and let your PC install the newly found drivers.
- If that's done click the Magnifying glass in the DC-Unlocker client software.
- If all is connected correctly your phone is detected and a message in the white part of the program will tell you so. Also the "Select Model" field should display Huawei HiSilicon Kirin Android if the detection is succesfull.
Now you're ready to read the unlock code! Yeah!
- Click in the right portion of the DC-Unlocker client on the tab Unlocking.
- Several buttons are visible but just click Unlock which could take a few moments before something is displayed in the white area at the bottom of the program window.
- The unlock code can be copied and pasted - so please do copy the number to a text file and store it savely on your computer or in your cloud.
You are the proud owner of the unlock bootloader code of your phone so have fun and start rooting it using the tutorials on this forum! Have fun!
Final note (once again): I did not have any success getting the unlock code using DC-Unlocker while using a Windows 10 PC. No matter which drivers I tried, no matter how many times a tried, tried and tried some more - nothing would work. The needed virtual COM ports to read the phone information couldn't be installed. Finally I've used an older Windows 7 laptop and it work like a charm!
So beware; when you've no luck using Win 10, stop wasting time and use a virtual machine or old laptop/PC which has Win 7 (maybe Win 8)!
