[HTC Butterfly S] koniiiik:
At last we have the 4.10.708.1 Sense 6.0 update for the HK version.

Unfortunately, this release appears to have some problems with the gallery and blinkfeed apps. For the best results, I recommend installing the previous version (3.06, linked below in this post) and applying the OTA update yourself.

Without further ado, here are the links!

If you are S-ON, after installing the ROM, you also have to unpack boot.img from the zip and flash it using fastboot:

fastboot flash boot boot.img

Verified to install without a problem on an S-OFF phone using the recovery built by [MENTION=3637908]kairi_zeroblade[/MENTION] in this thread.

For each of the available OTA updates, you can also find the actual OTA package, the firmware included within and the stock recovery for that version. If you want to flash the whole firmware package (including recovery, radio, kernel/boot and many other things), just grab the appropriate firmware.zip, rename it to PO68IMG.zip, put it into the root of your external SD card and reboot your phone into the bootloader – the update will be applied automatically.

Old versions below.

Here's the 3.06.708.3 KitKat 4.4.2 update.

Before installing, take a moment to read this. This update introduces extended filesystem capability flags and SELinux labels. The installer in this ZIP tries to set them in the same way as the OTA update does, but in TWRP this fails, because the recovery doesn't have support for these kinds of metadata. However, setting the medatada is done as the last step, so even if it fails and the installation aborts, the ROM is still installed properly, just without this extra bit.

I repeat:

Read the installer messages. If it says "Done!" and fails afterwards, the installation is complete. If it fails before printing the message "Done!", then the installation is not OK.

The latest CWM Touch should give the best results, although I haven't tried installing it through CWM.

If you are S-ON, after installing the ROM, you also have to unpack boot.img from the zip and flash it using fastboot:

[MENTION=1615671]Zarboz[/MENTION] also made a ZIP of this version of the stock ROM, I'm told it contains some flavor of Superuser preinstalled:

-----------------------

Just before Christmas we have a new stock ROM with Android 4.3 and Sense 5.5 available. Same as with previous version, the installer contains all preload apps, in addition, it also contains the HTC Notes app, otherwise it leaves /data as it is, so in case something does not work, remember to wipe data before installing.

-----------------------

This is an image of the stock ROM after installing the 1.23.708.3 OTA update. The installer also contains all preload applications (Flashlight, Calculator, PDF viewer and others). Other than installing / updating all preload apps, the package doesn't touch /data in any other way. If you need to wipe your data partition, do it before installing this ROM, otherwise you'll wipe your freshly-installed preload applications. (Note that some of them have been updated in the OTA, which means they differ from the APKs I posted separately.) Does not contain the Notes OTA update, it should ask after first boot.

Here's the download link:

-----------------------

Made from a dump taken from my 901S just after unlocking the bootloader, pure preinstalled stock ROM, no root, no mods of any kind. Only contains /system and kernel+initrd, doesn't touch /data, /cache or anything else. If you want a clean state, wipe your phone before or after installing.

The ROM is also available as a TWRP backup:

http://heh.sk/~johnny64/901S/stock-901s-twrp-backup.tar (MD5 here)

For those interested, I also made a backup of the original internal storage ("sdcard") before unlocking which is available here (MD5). It should be pretty close to the original state, though I did run a few apps there to get a feeling of the device.

Last but not least, there were certain applications preinstalled in the /data partition which gets erased completely when unlocking. I managed to find out which ones they were and back up their APKs. The APKs are located at http://heh.sk/~johnny64/901S/preload/. To install them, create the directory /data/preload on your device and push the APKs in there using adb or something. The apps should appear after a reboot. Most of them are probably not very interesting (since they are for news from the HK area), I was mostly interested in the calculator, flashlight and PDF viewer, but I backed them all up anyway, so suit yourselves.
