Faced the problem of inability to upload firmware in huawei e3531 / vodafone k4203. I open ports through sw_project_mode. And debug and project tried, everything opens, but with firmware it produces different errors, depending on the methods of the firmware and the firmware itself. How to flash: 1. I install the driver fc_serial, datacard_driver, mbservice (I tried it with and without) 2. I install the Vodafon software with zerocd, because only after installing it, at least a card begins to be seen. Modem in highlink mode 3. Open ports 4. Lew firmware.

What firmware I tried: 1. All firmware from the theme on e3531 for 4pd 2. BIN and exe firmware via flash_via_balongflash_2018-06-11 3. BIN and exe firmware via flash_via_pupdatewiz_01

I tried to solve problems through the method described on the forum with the help of the commands datalock-> godmode, did not help

The ultimate goal I have in the ideal: Put the firmware hilink and webui normal, not vodafonovsky, because it is limited in functionality strongly

The ultimate goal in the worst case: Turn off the cdrom so that the modem works without drivers in fedora. To turn off the cdrom I tried: 1. all variations of u2diag that I could google. Responds ERROR or CME + ERROR 2. SETPORTMODE in any version. Responds ERROR or CME + ERROR Tried to view the current composition via getportmode. Replies with this: Send: AT ^ GETPORTMODE Recieve: ^ GETPORTMODE: TYPE: WCDMA: Vodafone (Huawei).

In fact, I tried a little more than I wrote, but I didn’t even get a large sheet and roll it like that. Please help with what you can.
