do lcd displays have firnware factory

Now that we know the mainboard version, let"s head over to the creality3dofficial.com website. Head over to the support section and select "Firmware Download".

Here you see, there is different firmware versions for the different mainboards. In my case, I would have to select one of the 4.2.2 firmware builds and if you have the 4.2.7, you would select one of these other builds.

The selection depends whether you have a BLTouch in combination with that mainboard or not. We"re going to talk about the BLTouch installation in another video.

Now, we download the right firmware and what we get from the Creality website is a RAR file, which is similar to a zip file but windows cannot handle it unless you install something like winrar or 7-zip, which is what I"m using.

Now one little remark that I need to make here. If you already flashed this particular firmware to the printer and for any reason you like to re-flash the same bin file again to the printer, you need to rename it before you do this.

So because, I already have flashed this firmware version but I still want to re-flash it to show you the process, I am renaming it to some other name, ending with bin and I should be fine.

If you run into the issue of a black screen after doing this or the printer starts beeping continously, you somehow missed one of the steps or mistakenly tried to flash a wrong version of the firmware to your mainboard.

So I can really only replace the lcd screen to get it fixed? That is too bad. I wished Dell had better warning signals in place indicating to carefully check you system. I realise it is my own fault. However, I found out I am not the first one.

The LCD screen is vital for operating the printer. Should you encounter any kind of trouble, such as a dead screen, corrupted text, or other issues, please refer to the guide below.

First of all, unscrew the LCD screen from the printer frame, remove both M3x10 screw holding it the LCD board in the plastic casing, and remove it from the casing. See if the problem still appears when the LCD is not pressed by the casing.

Firmware updates are necessary to keep your printer up to date. However, the installation of incorrect firmware can lead to letter corruption on the LCD screen. There"s an easy fix, though:

There is a small chance the printer"s LCD screen can glitch out by electrostatic discharge when inserting the SD card. Try to turn the printer off and on again.

This problem usually appears only on user-assembled printers. If your printer"s LCD screen remains blank or displays corrupted symbols after you turn on the printer, there is a chance it is caused by incorrect wiring. Follow these steps to fix the issue.

Double-check that all cables are properly seated and they are not visibly damaged. Depending on the model of your printer, please refer to the following guides for information on how to make sure the cables are properly connected: Einsy RAMBo electronics wiring (MK3/MK3S/MK3S+) and Mini RAMBo electronics wiring (MK2S, MK2.5, MK2.5S).

If you suspect that the LCD ribbon cables connectors are not firmly seated in the slots, disconnect the LCD ribbon cables and check the slots for any bent pins. If there are bent pins, you can use tweezers to fix them. However, be very careful not to break the pin(s) completely.

If none of the above resolved the problem, turn the printer off again and try to unplug both of the cables, lay them down on a flat surface and gently stretch them. Then plug them back in and turn on the printer.

Keep your device connected and wait until the recovery mode screen appears:iPhone 8 or later, including iPhone SE (2nd generation): Press and quickly release the volume up button. Press and quickly release the volume down button. Then, press and hold the side button until you see the recovery mode screen.

iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold the top (or side) and volume down buttons at the same time. Keep holding them until you see the recovery mode screen.

Locate your device on your computer. When you see the option to Restore or Update, choose Update. Your computer will try to reinstall the software without erasing your data. Wait while your computer downloads the software for your device. If the download takes more than 15 minutes and your device exits the recovery mode screen, let the download finish, then repeat step 3.

If your phone is frozen and does not respond to key presses, you can also reboot simply by unplugging and replugging it (if the phone is powered by POE you would unplug the network cable.)

Before upgrading the firmware manually you should read the relatedfirmwarerelease notes (find them by selecting the SOFTWARE RELEASES orSOFTWARE RELEASES ARCHIVES tabunder the support pages for Trio 8300, Trio 8800, or Trio C60) and possibly consult with Poly"ssupportto ensure there are no compatibility issues or other potential conflicts. If such issues or conflicts do happen after an upgrade you may need to downgrade to a previous firmware version, if possible, or perform a factory reset.

When new software is available a notification is displayed on your phone and you have the option to update your software, postpone the software update, or exit the notification.

If you do not update the phone"s software after your selected postponed time, a countdown is displayed and the phone automatically reboots and updates the software when the countdown ends.

If you postpone a software update and the time period you chose ends while you"re on an active call, a countdown is displayed after the call ends and the software update is triggered afterward.

You also have the option to completely stop the automatic software update by selecting Exitwhen the update notification appears. You can go back to the automatic software update by selecting SWUpdate.

Select the software version you want to update to from the Software Available at Polycom Server drop-down menu and click Install.Click Yes to approve the installation and then Accept the license agreement.

There are three ways to perform a factory reset – from the phone"s settings screen, from the web configuration utility, or by holding a keys combination/the touch-screen corners during a reboot.Do not unplug your phone while the phone is resetting.

If your phone is frozen and does not respond to the above methods you can restart it simply by unplugging and replugging it (if the phone is powered by POE you would unplug the network cable.) It is still advisable you try to use the above methods whenever possible.

When you trigger the configuration update the new configuration file is downloaded from a provisioning server to the phone"s flash memory and the update process is completed automatically.

Before upgrading the software manually you should read the relatedsoftwarerelease notes that you can find by selecting theSOFTWARE RELEASESorSOFTWARE RELEASE ARCHIVEStab under theVVX 401/411support page. You should also possibly consult with Poly"ssupportto ensure there are no compatibility issues or other potential conflicts. If such issues or conflicts do happen after an update you may need to downgrade to a previous software version or perform a factory reset.

When new software is available a notification is displayed on your phone and you have the option to update your software, postpone the software update, or exit the notification.

Instead of updating your software immediately, you can choose to postpone the update from 15 minutes up to six hours. To do so select Postpone when prompted to update your software and select one of the time options. The notification is removed from the screen until five minutes before the postponed time you selected.

If you do not update the phone"s software after the postponed time, a notification with a countdown is displayed and the phone automatically reboots and updates the software when the countdown ends.

If you postpone a software update and the time period you chose ends while you"re on an active call, a software update notification with a countdown is displayed after the call ends. After the countdown ends, the phone reboots and updates the software.

When the software update notification is displayed, you also have the option to exit the notification without choosing to update or postpone the software by selecting Exit.

To perform a factory reset during a restart (with the option to override the admin password):Before proceeding with the factory reset you may need to know the phone"sMAC address.You can find the MAC address by doing one of the following:Look for a sticker on the bottom of the phone. It is a 12 digits hexadecimal number that usually starts with 0004F.

If the default admin password is not accepted you need toenter the MAC Address as explained above, using capital letters! But before doing so you should contact us or your phone system administrator to see if we or he have a record of the current admin password!Pay attention to the difference between entering digits, capital, or lowercase letters. To switch between letters and digits press the input modifier softkey. It initially appears as1->Aa, indicating you are entering digits. When entering capital letters it displays asA->a1.Each numeric key on the dial pad has three letters on it. Press it once to enter the 1st letter, twice (without pausing) for the 2nd letter, and three times for the 3rd.As you type, pause briefly between each character.For security, the characters you enter are shown only as asterisk symbols (*).If you made a mistake you can press the Left Arrow key to delete the last character.

Do not unplug your phone during the reset process and do not press any keys. After the process is finished the admin password will become the default 456.

If your camera has either of these issues, please perform a factory reset of the camera as shown in the steps below.After the factory reset, do not remove the battery from the camera for more than 12 hours. This helps ensure that you don’t run into this issue again. If your camera continues to show a green screen or is in a reboot cycle, please contact us so we can gather more information.
