+# NOTE: These kernel files are not required, unless you are having problems resulting from having inadvertently overwritten the DGUS2 kernel for which your display was last calibrated.
+
+## STEP1 - BEFORE ACTING ON ANY OF THE FOLLOWING RECOMMENDATIONS:
+1. Create an EMPTY folder at the root directory of an EMPTY micro SD card.
+2. Ensure that your printer power is OFF
+3. Place that SD card in your display and cycle power ON
+4. The top line of the display will report which version of DGUS2 is currently flashed .  
+4. Make note of which DGUS version is currently flashed to your display hardware (see top line on display)
+5. Take care to follow the applicable instructions below.
+
+## IF your display is currently running v3.5 and it should be running v4.5:
+STEP 2: 
+1. Copy T5L_UI_DGUS2_V45_20220105.BIN to the DWIN_SET folder created at step 1 above, and flash that to your display.
+2. Verify that the top line on the blue flash screen is now overwritten in red confirming that DGUS2 v4.5 is flashed
+3. Optionally repeat step 1 with an empty DWIN_SET folder, to confirm v4.5 is now the DGUS2 OS
+
+# OR
+
+## IF your display is currently running v4.5 and it should be running v3.5:
+STEP 2: 
+1. Copy T5L_UI_DGUS2_V35_20200730.BIN to the DWIN_SET folder created at step 1 above, and flash that to your display.
+2. Verify that the top line on the blue flash screen is now overwritten in red confirming that DGUS2 v3.5 is flashed
+3. Optionally repeat step 1 with an empty DWIN_SET folder, to confirm v3.5 is now the DGUS2 OS
+
+
+# Here is how to interpret what you see:
+
+The top line of the blue boot screen always identifies the current DGUS2 OS in white text.
+
+If the DWIN_SET folder being flashed contains a DGUS kernel BIN file, the top line is overwritten in RED text, reporting the version that has been flashed.
+
+If the two lines are different, it may be difficult to read either line.
+
+If the two lines are identical, the current DWIN_SET folder has reflashed the same kernel to the display.

+The following issues have been observed but not resolved, at this DRAFT release:
+
+1. The ABLprocess no longer uses the contents of 35_Autolevel.icl to animate the collection & display of the mesh data.  To enable old eyes to read the mesh, the normally white background of the initial screen has been changed to black.  As a result, when the process first initializes all of the values to 0.000 in white, those zeroes are now visible to the user, until replaced by the probing process. This will not look familiar to past users of 6.1, but should not be a problem for new users.
+
+2. Although we have added the display of temperature readings and target values to three thermal warning screens, initial testing shows that the displayed values are all zeroes, instead of the hoped-for dump of the values "seen" by Marlin, if there is already a short-circuit on one or both thermistors, when the printer is powered-up.  
+The modification did work as intended if the short circuit occurs after the printer has powered-up. The Heating Failed error condition was also confirmed to correctly display the thermal data.  
+We have not yet determined how to test the Thermistor Error screen. 
+We continue to investigate whether we will also require a mainboard firmware change to fully implement this particular modification.
+
+IF you find any other issues, please message @Thinkersbluff with the key info.  TIA!

+# Release#: 61F_RC_260522_v1
+
+## NOTE: As of this release, the release# is branded in orange on the load screen and on the Setup->INFO screen. If you do not see this release number on your system, you have not flashed this version of the touchscreen firmware. 
+
+# Introduction
+
+## NEW at this release:
+
+### New at v1: 
+
+1. Added new button to the Setup Control Screen, to access the Leveling Settings Screen from Setup
+2. Corrected a configuration error in the source project file, which was preventing the display of the two Toggle switches on the Setup Screen.
+3. Deleted a temporary jpg file used during the creation of 61F_RC_090522_v2, which should not have been included in that release.
+
+
+
+## Background
+
+The CF6.1 touch screen firmware was designed and distributed to run on the DGUS2 v3.5 operating system.
+
+Creality has now begun delivering the CR6 printers running a more recent version of DGUS2 (v4.5, at the time of this release.) 
+
+DGUS2 v4.5+ requires a different calibration of the display screen to run than did v3.5.
+
+Following the CF6.1 installation instructions to flash v3.5 with CF6.1 to these newer printers therefore causes the v4.5 screen calibration to be invalid. That results in the touchscreen becoming non-responsive to CF6.1. Reverting to Creality stock also then fails, until the DGUS2 v4.5 kernel is restored to the display.
+
+This re-factored version of the firmware will operate correctly on all CR6 printers flashed with DGUS2 OS version 2.0 or higher, as long as:
+1. The motherboard has also been flashed with the correct configuration of CF6.1-Final firmware
+
+2. The display hardware has already been calibrated to operate with the version of DGUS2 (2.0 or higher) that is installed on the display.
+
+
+
+# Recommendations for using this firmware
+## _PLEASE read all of these recommendations, before following any of them._
+
+**NOTES:**
+
+**1. As always, flashing this firmware to your system is done entirely at your own risk. The CR-6 Community firmware developers take no responsibility for any consequences of flashing this firmware to your system.**
+
+2. Some users whose displays showed DGUS2 v4.5 running before flashing this refactored DWIN_SET had a screen of "white noise" at the end of the flashing process, instead of the expected blue END! screen. That noise screen usually indicates that the display orientation has been changed, upon initialization of the DGUS2 OS.  The file T5LCFG_272480.CFG in DWIN_SET is a configuration file, which includes an instruction to orient the display to 270 degrees (portrait mode).  Removing that file from DWIN_SET and reflashing should stop that noise screen from appearing.  We are still investigating why the screen would reorient when it is already in portrait mode. Those users report that this work-around did stop the noise screen appearing and that their printers  work correctly after flashing a second time, with that file removed.  
+
+3. We have seen STEP1 display DGUS2 v4.5 with a different date stamp than the one bundled with this release. (13/01/22 vs 05/01/22) We can not explain why DWIN would publish two variants of the same OS version, nor can we answer whether there are any differences between the two. (See note 1)
+
+
+**STEP1 - BEFORE ACTING ON ANY OF THE FOLLOWING RECOMMENDATIONS:**
+1. Create an EMPTY folder at the root directory of an EMPTY micro SD card.
+2. Ensure that your printer power is OFF
+3. Place that SD card in your display and cycle power ON
+4. The top line of the display will report which version of DGUS2 is currently flashed .  
+4. Make note of which DGUS version is currently flashed to your display hardware (see top line on display)
+5. Take care to follow the applicable instructions below.
+
+
+### If you are currently running Creality stock firmware on your system, and your display is currently running DGUS2 v4.5+
+
+Flash this touchscreen firmware INSTEAD of the CF6.1-Final touchscreen firmware.  
+
+1. Ignore the Touchscreen firmware folder in the CF6.1-Final release zip file.
+
+2. INSTEAD, copy the DWIN_SET folder and contents from this release to the micro-SD card you use to flash the display 
+
+3. DO NOT copy ANY DGUS2 kernel upgrade files to the DWIN_SET folder before flashing it to your display.
+
+### If you are currently running Creality stock firmware on your system, and your display is currently running any version of DGUS2 between (and including) v2.0 and v4.4 (e.g. v3.5)
+
+EITHER: Go ahead and flash the CF6.1 TouchScreen Firmware to your system, following the CF6.1 Touchscreen Firmware README instructions precisely
+
+OR:
+
+Do exactly the same thing as recommended above for the v4.5 users:
+1. Ignore the Touchscreen firmware folder in the CF6.1-Final release zip file.
+
+2. INSTEAD, copy the DWIN_SET folder and contents from this release to the micro-SD card you use to flash the display 
+
+3. DO NOT copy ANY DGUS2 kernel upgrade files to the DWIN_SET folder before flashing it to your display.
+
+### If you already flashed the CF6.1-Final touchscreen firmware to your display hardware, your display is now running DGUS2 v3.5, and your display is non-responsive
+
+You can flash this re-factored version of the CF6.1 UI to your display and restore the display to running DGUS2 to v4.5, as follows:
+
+  1. Delete the DWIN_SET folder from the SD card with which you previously flashed your display. (Make sure you keep a copy, just in case!) OR prepare a new blank micro SD card.
+  2. Copy the new DWIN_SET folder distributed in this release to that SD card  
+  3. Copy T5L_UI_DGUS2_V45_20220105.BIN from the DGUS2 kernel upgrade files folder into the new DWIN_SET folder on that card
+  4. Re-flash your display with the updated card
+  5. Verify that the top line of the display shows the DGUS2 v4.5 OS was flashed as part of the process (it will be written in red text over the top of white text that said v3.5)
+  6. Power off the printer
+  7. Remove the SD card from the display and power it back up
+  8. The CF6.1 interface should now work correctly
+  9. Repeating the empty DWIN_SET folder trick described as STEP 1 above will allow you to confirm with confidence that DGUS2 v4.5 is now flashed to the display
+
+## Instructions for Reverting a Display to the Creality Stock Firmware
+
+### If you flashed the CF6.1 firmware and the DGUS v3.5 kernel upgrade files to a DWIN display that was previously configured to run on DGUS2 v4.5 and just want to revert to stock, rather than flashing this firmware release
+
+1. Copy the T5L_UI_DGUS2_V45_20220105.BIN kernel upgrade file into the Creality DWIN_SET folder. 
+2. Re-flash that DWIN_SET to your display. 
+3. Re-flash the stock Creality firmware to the motherboard
+
+The printer will now have been reverted to the Creality stock firmware.
+
+### If you successfully flashed CF6.1 or this release to a DWIN display without flashing any DGUS kernel upgrade files to that display, but now wish to revert to the Creality stock firmware
+
+Flash the stock Creality firmware back to the motherboard and the display, per Creality's instructions.
+
+## Instructions for reverting from this re-factored version BACK to the CF6.1-Final TouchScreen Firmware on a display running DGUS2 v3.5 
+
+Follow the flashing instructions in the CF6.1-Final Touchscreen firmware README file.
