While I'm currently fully on stock, is there any way to extract the stock recovery now, before I replace it with TWRP? Do I even need to do that if I have entire RUU zip or will recovery be restored when I flash the ZIP through htc_fastboot?

I have seen links to ruu.lalleman.net with stock recoveries and RUUs, but the links are dead now.

My HTC M8s is fully stock now and I want to try Lineage 15.1 from https://src.voidzero.net/ (unless you can suggest some even more stable ROM with at least Android 7). I found twrp-3.2.3-0-m8qlul.img also on the same website, and also MindTheGapps-8.1.0-arm-20180808_153837.zip, so it should all work together nicely (I hope).

But before I go on, I want to make sure I can return back to stock. So, I have obtained RUU 0PKVIMG_M8_QL_UL_M60_SENSE70_MR_HTC_Europe_2.21.401.1_Radio_1.0.U20410.1@60201_20.05_018_F_release_496316_signed_2_4.zip that matches my radio number and currently installed mainver number. However, I can't find the stock recovery anywhere.

Here's my fastboot info:

  • @alecxs The RUU zip I got is not encrypted, I can extract all files freely. However, there seems to be no recovery inside. At least, I don't see any recovery.img or anything like that. Commented Oct 6, 2021 at 7:15

  • That's an old thread, I have already asked a few questions about M8s but nobody cares about such an old phone and all links are dead. But it seems, I found a workaround: fastboot boot twrp-3.2.3-0-m8qlul.img, run backup tool in TWRP, choose everything from there and back up to a USB OTG flash device. Hopefully, this TWRP backup will be enough to be able to restore the phone fully back to original, including recovery. Commented Oct 6, 2021 at 8:01
