[HTC Desire 601] -Duir-:
This is for all variants of the Desire 601

From their site (comments in green are added by me):

Team Win Recovery Project 2.x, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Up-to-date phone look photos:

What's new in 2.8.6.0:

Fix daylight savings time rules for USA and Europe (_that)

Allow multiple overlays for popup boxes (Dees_Troy)

Add pattern style password entry for decrypt (Tassadar)

Various scaling improvements (Dees_Troy)

Improved handling of resources in the GUI (_that)

Make scroll bar size proportional to list size (_that)

Allow scroll lists to render without a header (_that)

Make console scroll per pixel with kinetic scrolling (_that)

Support styles in XML to reduce XML size and improve consistency (Dees_Troy)

Various other fixes and improvements (mdmower, bigbiff, codelover, etc)

What's new in 2.8.5.0:

Scale the GUI - TWRP can read the theme's resolution and scale it up or down to fit the theme to your screen's resolution

Improve thread handling and move input handling into the main rendering thread to improve stability

Make MTP work even if unplugged and plugged back in

Unify scrollable list code and make kinetic scrolling feel more natural

Fix handling of mapped zip files for OTA updates (CM12 updater)

USB keyboards should now work on all devices that support USB host mode via a USB OTG cable

Other small fixes and improvements

What's new in 2.8.4.0:

MTP fixes and improvements - you can now copy zips to the root of storage - thanks to _that

Add flashing of boot and recovery images via the TWRP GUI (Find the Images button on the Install page)

Fix some MTP related crashes and bugs

Eliminate TWRP toggling USB IDs during boot if MTP is enabled

Fix various adb sideload issues

Improve threading of actions

Eliminate separate thread for screen timeout

Update libblkid to 2.25.0

Use power button as back button on watch themes for easier navigation

Add mutex locking to data manager

Improve custom theme handling on encrypted devices

Allow the stock theme to be offset by build flags so we can center a lower res theme on a higher res screen especially for watches with round screens

What's new in 2.8.3.0:

MTP will now tell the host PC that storage is removed instead of disabling MTP completely

MTP will now report the correct max file size based on the file system in use to the host PC (may fix transfer of large files)

Update and improve fix permissions and make fixing contexts optional

Update SuperSU in TWRP to 2.40 and update install process

Make TWRP work properly on AArch64 (Nexus 9 is now built in true 64-bit binaries and libraries)

Attempt to set correct permissions and contexts on all files placed in storage so backups will show in Android

Fix kernel panic during MTP start on some devices

Support unicode fonts on devices with True Type Font support

Fix slider value not showing sometimes (vibration settings page)

Toggle MTP off during adb sideload to set correct USB IDs

Reduce library requirements for 5.0 L decrypt

Other minor fixes and improvements

Note: Starting with TWRP 2.8.2.0 and higher, adb sideload uses a new sideload method originally implemented in AOSP recovery. You will need the latest adb binaries to use sideload in these newer versions of TWRP. The version required is 1.0.32. You can find the version by running "adb version" on your computer. The new sideload feature no longer stores the zip on your device. Instead, a fuse file system is created in RAM and the zip is streamed from your computer. This puts less wear and tear on storage and ensures that large zips will not fill up all of your RAM. The sideload may spit an error on your PC side, but the zip should install just fine on your device.

What's new in 2.8.2.0:

(This build was only officially released on select [mainly nexus] devices)

Pull in all changes from Android 5.0 lollipop into TWRP

Add decrypt support for Android 5.0 lollipop encrypted partitions including automatic decrypt when the default_password is in use

Revert some changes to exFAT that were breaking exFAT support on some devices

Other minor fixes and updates

Note: At this time we do not have a GUI representation for pattern unlock. You can still decrypt patterns though by translating the pattern dots to numbers. The pattern dots correspond to numbers in the following pattern:

1 2 3

4 5 6

7 8 9

So an upper-case L would translate to a password of 14789 entered on the keyboard. Eventually we plan to add a proper pattern unlock to TWRP but it is a relatively low priority at this point.

What's new in 2.8.1.0:

MTP fixes and improvements - you can now copy zips to the root of storage - thanks to _that

TrueType Font support - optional as it takes up a decent amount of space so may not be available on all devices - thanks to Tassadar

Temperature support - thanks to bigbiff

Various other bugfixes and tweaks

What's new in 2.8.0.1:

Fix a bug that caused weird graphics and touch issues

What's new in 2.8.0.0:

Add MTP support to recovery thanks mostly to bigbiff with a little help from Dees_Troy

Add command line capabilities - you can now execute various TWRP features via adb instead of the touchscreen

Add support for color in the console and give error, warning, and highlight lines different colors

Track backup and restore progress based on file sizes to provide a much more accurate indication of progress

Improve handling of /misc thanks to mdmower

Improve setting of time on Qualcomm devices thanks to [NUT]

Allow using images on slidervalue GUI objects thanks to Tassadar

Allow using variables and addition and subtraction in variables for easier theming

Add support for 1440x2560, 280x280, and 320x320 resolutions and update 240x240

Allow ui.xml file to include additional xml files to help break up the theme and make TWRP easier to maintain

Other minor fixes and improvements

Including screenshots: "Power"+"Volume Down" will now save a screenshot to /external_sdcard/pictures/screenshots.

Over the course of the last year or so, bigbiff has worked to migrate various Java functions from Android's MTP implementation to bring you a fully C++ based MTP implementation that allows you to transfer files to both emulated storage and Micro SD cards. It's confirmed to work on various Nexus devices but we may have to make some changes on other devices to keep Windows happy. Windows is very picky about USB IDs and its drivers. We have tested it on Windows 7 and 8 as well as Ubuntu 14.04 Trusty. MTP is enabled by default, but we do toggle it off and on automatically during certain operations such as if you choose to wipe a storage partition. You can enable or disable MTP under the mount menu in TWRP. For more about what MTP is here.

Note: Due to a weird bug with our MTP setup, you cannot copy a zip file to the root of storage with Windows. You can change the .zip to something else like .txt and then copy it to the root and rename the file back to .zip once it's copied to the device. You can also copy the zip into any subfolder.

Command line support is also now available. You can perform various OpenRecoveryScript commands via the adb shell. Depending on what you are doing you may wish to do a "twrp set tw_mtp_enabled 0" and then reboot to prevent the MTP auto toggle from killing your adb interface. You can use this option to create and restore backups, wipe, install zips, and more. Via adb shell, type twrp followed by a space then enter the OpenRecoveryScript command and hit enter. Find more OpenRecoveryScript commands here.

What's new in 2.7.1.0:

Add GUI option to change or repair file systems on individual partitions. The change is destructive so backup your data including internal sdcard first. This option should make it a little easier to migrate a device from ext4 -> f2fs, for instance. You will find this option under Wipe -> Advanced Wipe, then select only one partition and then press the Repair or Change File System button. If a developer has added f2fs support for your device and we don't have it in TWRP, please contact me via PM to arrange for it to be added.

Various bugfixes to backup and restore

Improvements to USB storage handling

Added a class to search for files to make finding the correct brightness file automatic in most cases

Various other bugfixes and tweaks

What's new in 2.7.0.0:

Faster graphics rendering by disabling alpha blending on fully opaque objects thanks to Tassadar

Allow sideloading from /tmp on encrypted devices

Check for a crypto footer before asking for a password to prevent user confusion

Additional checks for validity to auto generated backup names

Text wrap in the console output

Proper caps lock support in the keyboard

Mouse support via USB OTG for devices with a broken digitizer

Improve scanning of storage locations for OpenRecoveryScript

Haptic feedback for buttons, keyboard, and vibration at the end of longer running actions thanks to Samer Diab

Fixed ext4 wiping when no selinux contexts are defined for that partition (e.g. sd-ext)

Update SuperSU to 1.93 and improve installation process

Added selinux contexts restoration to fix permissions

Load RTC offset on Qualcomm devices to fix the date/time in recovery

USB Mass Storage fixes Add SELinux support checking

Add Disk Usage class to better handle excluded folders (e.g. Google Music cache)

Add 4.4 decrypt support

Add some toolbox utilities to TWRP (namely to support SELinux functions not supported in busybox)

Various SELinux fixes and bug fixes

Note: 2.7 marks the first time that we are dropping support for older devices. We are doing this because of the SELinux support needed to install 4.4 Kit Kat ROMs. The non-TWRP parts of the recovery image have to be built in at least a 4.1 tree and the kernel that is included in the recovery image has to support writing SELinux contexts. We don't own most of the devices that we support so we depend on outside testers and developers to help us update devices. In many cases we can't find someone readily. Come to #twrp on Freenode if you want to help bring your device up to date. You can tell right away if your device will support 4.4 ROMs in 2.7. Boot TWRP and press the console button (the square-ish button either in the bottom middle or upper right) to view the console output. If it doesn't say "Full SELinux support" in the console, then your device still needs some work. Help us help you.

What's new in 2.6.3.0:

Proper backup and restore of SELinux contexts (thanks to Tassadar)

Pull in some ROM information for backup name generation

Merge all recent patches from AOSP bringing TWRP up to date with Android 4.3

Add 1200x1920 theme (thanks to Tassadar)

A few other fixes and tweaks

NOTES:

This is the official version of TWRP for our device only modified with the updated partition mount points as changed by the KitKat OTA.

I have also modified it to display the version to show "(KK)" to visibly distinguish it from the official version.

This is only for Desire 601 users who have updated to KitKat or, at the very least, attempted the update and had their partitions remapped. If you have not updated to KitKat using the OTA you need to use the original version which can be found on their website here.

This is for all variants of the Desire 601 - zara_cl and zara_ul
