| This guide details the methods to update the firmware on WizarPOS devices. Ensure that the firmware package is obtained from WizarPOS. Here are the Methods of Updating Firmware.
| |
| == Using a TF-Card (When Terminal is Off) ==
| |
| * '''Preparation:'''
| |
| ** Format a 4G to 16G TF-Card to FAT32 and name the folder 'wizarpos' (in lowercase). Refer to '[[How to Select Optimal TF Card (Micro SD Card) for Smart POS Systems]]' for compatible card types.
| |
| ** Ensure the folder structure on your TF-Card matches the example provided.

| |
| * '''Update Process:'''
| |
| ** Power off the terminal and remove the battery.
| |
| ** Insert the prepared TF-Card into the terminal.
| |
| ** Power on the terminal. The update will commence automatically.
| |
| ** After the update, the terminal restarts. Verify the update by checking the 'Build number' and 'Kernel version' in 'Settings > About POS'.
| |
| * '''TF-card Location in Q2:'''

| |
| == Using a Thumb Drive ==
| |
| * '''Requirements:'''
| |
| ** Ensure the PosSysAssistant application version is at least 2.11.22.
| |
| * '''Preparation:'''
| |
| ** Create a directory "\cloudpos\image" on the thumb drive.
| |
| ** Depending on the firmware package's root folder, copy the 'xxx.zip' file accordingly (refer to detailed instructions).
| |
| * '''Update Process:'''
| |
| ** Connect the thumb drive to the terminal using an OTG-USB host converter.
| |
| ** Select the firmware file from the pop-up message.
| |
| ** After copying the firmware to internal storage, restart the terminal to apply the update.
| |
| ** Verify the update in 'Settings > About POS'.
| |
| == Using a TF-Card (When Terminal is On) ==
| |
| * Follow the same steps as the thumb drive method.
| |
| * '''Note:''' This method is not applicable for Wizarhand Q1 models as the battery must be removed to insert the TF-Card.
| |
| == Using WizarView ==
| |
| *For remote firmware updates, refer to the '[[How to update firmware remotely]]' guide.
| |
| == Using Application Interface ==
| |
| * WizarPOS provides an AIDL interface for third-party applications to update system firmware.
| |
| * Refer to the attached [http://ftp.wizarpos.com/UpdateSystemDescription_1.1.docx documentation] and [http://ftp.wizarpos.com/SystemUpdateTest.zip Demo] for guidance. Note that the firmware system package must be obtained from WizarPOS.
| |
| '''Post-Update Verification：'''After any update method, confirm the new 'Build number' and 'Kernel version' in 'Settings > About POS' to ensure the update was successful.
