HTC One M8 Booting Issues with Lineage OS: A Comprehensive Guide

Are you experiencing bootscreen reboots and inability to boot your HTC One M8 after successfully installing Lineage OS? You are not alone.

The Problem: Persistent Bootloader Reboots

Your device reboots to the bootloader screen, indicating a possible issue with the boot process. The device shows 'always s-off' and the bootloader is unlocked with a super CID of 11111111. This situation can be perplexing and frustrating.

Troubleshooting Steps

Firstly, let's discuss the steps you can take to resolve this issue. One effective method is to boot into the recovery mode and proceed to the advanced wipe. In particular, the Cache partition can be deleted to fix any lingering issues. After performing this wipe, try a reboot. If this step does not resolve the issue, additional information is necessary to provide a more informed response.

According to other responses, booting to recovery and using the advanced wipe might not be necessary if your device boots without Google Apps (Gapps) or proprietary modules. However, the absence of booting issues with Gapps installation suggests that there might be compatibility issues related to the Android version and the Lineage OS you are using.

Compatibility and System Requirements

One possible solution to your issue is to update your bootloader and modem versions. If you are booting into a much earlier Android version compared to the Lineage OS version, you might need to flash a later bootloader and modem to ensure compatibility. This step can potentially resolve the booting issues if the underlying device hardware is supported by the updated bootloader and modem version.

Specific Recommendations

Before proceeding with any software flashing, ensure that you:

Are using the Lineage OS ROM specific for your model (HTC One M8). Flash the required Gapps package immediately after installing the Lineage OS. Follow the official Lineage OS setup instructions carefully. Backup all your critical data before proceeding with any flashing operations. Use reputable sources for Lineage OS ROMs and Gapps packages to avoid potential security risks and incompatibilities.

Conclusion

Booting issues with the HTC One M8 and Lineage OS can be challenging, but with the right troubleshooting steps, you can often resolve these issues. If you continue to experience problems, it may be beneficial to reach out to the Lineage OS community forums or seek assistance from a professional.

Remember to keep your device and its software up-to-date to ensure the best performance and security.
