Download AT&T HTC One M7 Lollipop Update RUU 7.23.502.1

AT&T began rolling out the Lollipop update for HTC One M7 about a week ago. The update was pushed as an OTA in two separate parts. That roll out is now complete but for some reason if you weren’t able to take the OTA update on your AT&T One M7, then RUU for software number 7.23.502.1 is now available for you to download Lollipop right now on your device.

The 7.23.502.1 RUU comes with Android version 5.0.2. This isn’t the latest of Android right now since Google has already released Android 5.1 which contains a number of pretty little features and also significantly boosts performance. HTC has said that One M7 will receive the Android 5.1 update, but we aren’t sure if/when AT&T and carriers would make it available.

NOTE: If you’ve an unlocked bootloader with S-OFF, then you can install the RUU easily. However, if your One M7 has unlocked bootloader with S-ON, then you’ll have to re-lock the bootloader first to be able to install the RUU update.

        • Error 155 occurs when you’ve an unlocked bootloader. Although you’re saying you’ve locked bootloader, I’d recommend you to lock it once again. Also, do check this link — http://forum.xda-developers.com/showthread.php?t=1655832
