How to Get Rid of the Annoying Red "Development Build" Text on Your HTC One M8's Bootsplash
HTC thought it best to cover their own ass by placing a red warning whenever you start your device if you've unlocked your bootloader. While it may help them identify a tampered phone, it does not help you in any way.
Luckily, XDA member santod040 created a modified HBOOT that removes the "This build is for development purposes only..." text for you. While this will modify HBOOT, it will not change your unlocked or S-Off status.
The new HBOOT will be flashed in RUU mode, which is like a special recovery mode that can only be accessed through fastboot. You should keep in mind that the HBOOT you download is specific to your device, so be sure to double check when clicking the download links below.
- This process requires an S-Off device, so be sure to have that.
- You will also need to have ADB/Fastboot installed on your computer.
- Enable USB debugging on your device.
- I would recommend that you back up your data as well. This will not wipe your device, but its never a bad idea to have a fail-safe.
To get your device in RUU mode, you will first have to put it in fastboot mode. The easiest way to do that is to connect your M8 to your computer and input the following command into a terminal window (Terminal on Mac; Command Prompt on Windows):
- adb reboot bootloader
After you see the fastboot menu on your M8, you can send the command to put your device in RUU mode.
- fastboot oem rebootRUU
If you did it right, you will see a black screen with a silver HTC logo on it.
As I said previously, there are different HBOOTs for each version of the M8. You can check the original XDA thread for your HBOOT, but I will also link to some of the more popular carrier below.
After you have the HBOOT file downloaded, rename it to hboot.zip and place it on your Desktop. After that, you are all set to flash:
- fastboot flash zip Desktop/hboot.zip
Change the "Desktop/hboot.zip" if you didn't rename or move the file. You will see the flash take place through ADB, and a green progress bar will show up underneath the HTC logo on your M8.
Now that you have your new HBOOT set up, all that's left is to reboot and check out your new boot screen:
- fastboot reboot
It would be great if there was a one size fits all HBOOT, but unfortunately that's not the case. When there is a modified HBOOT released for the T-Mobile M8, I will be sure to let you guys know!
Again, I would like to remind you that this will not modify any other files on your device, just the HBOOT. If you run into any hiccups, be sure to let me know!
