[Miscellaneous Android Development] Unjustified Dev:
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.

CHANGELOG for 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

-Backups can now be cancelled while the backup is in progress (does not include restore because we don't want to leave your device in a bad state)

-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

CHANGELOG for 2.8.4.0:

-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

CHANGELOG for 2.8.2.0:

-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.

Also note that you will need the latest adb binaries on your computer to sideload with this new version of TWRP.

CHANGELOG for 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

CHANGELOG for 2.8.0.1:

-Fix a bug that causes weird graphics glitches and touch issues

CHANGELOG for 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

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.

CHANGELOG for 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

BUGS:

If you have found a bug, please consider posting it to our github issues log. It's pretty much impossible for us to keep up with the more than 40 threads that we have for the devices that we "directly" support. If you have a significant problem that cannot be answered in this thread, your best bet is to PM me directly, contact us via our website, or find us in our IRC channel below. If you see someone that's struggling, feel free to point it out to us. We need your help to help us keep track of all of our devices! Thanks!
