By investigating the mentioned patches directly, the existing behavior should not be changed:
* The patch for Quectel EM160 4G There is only one patch, all changes are for the Quectel modems. * Patches for Foxconn T99W175 There are 5 patches, (patch#1): Modify the command line tool to get additional scan report for WWAN subsystem (patch#2): Move methods between 2 files (patch#3): Add more 15 seconds wait for the firmware upgrading (patch#4): Rename an existed carrier mapping configuration file for Foxconn modem (patch#5): Add a new carrier mapping configuration file for Foxconn modem From the code review, it's clear that changes only affect Foxconn and Quectel modems. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1946096 Title: Support manual firmware upgrading for Foxconn and Quectel modems. Status in OEM Priority Project: In Progress Status in modemmanager package in Ubuntu: New Bug description: [Impact] The modem certification requires that different modem firmware is used for different network carrier. This needs the firmware upgrading capability during the modem certification process. The modem manufacture vendors (Foxconn and Quectel) provided utilities to do modem's firmware upgrading manually.(LP#1943774, LP#1943780) These utilities are verified to be working when the recent versions(> v 1.18.2) of ModemManager are used with. To support manual firmware upgrading on the current Focal release which is using ModemManager v 1.16.6, we need to apply some patches from v 1.18.2. The requested upstream patches are listed as below: * for Quectel EM160 4G ** https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/83ac82470589a3672092a0ba0be855093b1cf5e2 * for Foxconn T99W175 ** https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/21ae558fe3600c84b3ca7dcd9bf50a3ba576c7c9 **https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/76e700f4fd703f952208993330ab098305c13d6b ** https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/52bf2c641171ded9e617022f40497c8984520371 ** https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/33e2b023ef01bea9da37ae2beb192f7d92bce47a ** https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/f72046701659073fbfa97516e155865647acb154 The firmware upgrading was verified using the patched ModemManager v 1.16.6 with the following 2 modems: * Foxconn SDX55 T99W175 5G sub6 PCIE Modem * Quectel SDX24 EM160R-GL 4G LTE CAT16 PCIE Modem [Test Plan] 1. Install the Ubuntu image. 2. Boot and login the system. 3. Prepare the modem’s firmware and install the firmware upgrading application provided by Foxconn and Quectel 4. Using the firmware upgrading application to upgrade the modem’s firmware 5. Verify if the modem’s firmware upgrading is successful 6. Reboot 7. Verify if the upgraded modem firmware is still working [Where problems could occur] The requested upstream patches are for these 2 specific modems. This should not affect existing generic functions and other modems. [Other Info] The firmware and the upgrading utilities can be downloaded from the following link: * LP#1943774 for Quectel modems * LP#1943780 for Foxconn modems To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1946096/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
