I tried the step 6 again and when the screen show "battery error", i put the battery carefully and the screen change to huawei logo but on device manager, the device it's not recognized. (image attached: 1.png)

probably driver related, if you installed the proper drivers in the requirements then whenever windows tries to search online for the drivers simply click on "Skip obtaining driver software..." . it should proceed to installing the locally found drivers
BTW is the device now able to boot properly now?

I think you don't understant. The device reboot before finish update wizard. When the update wizard start "restore users information", the router reboot and show "battery error" on screen but on device manager(windows) he never recognized with device and the setup wizard it's not completed because he can find the router. 

I think my router is broken/damaged Sad

Note: When the setup wizard start, the router is correctly recognized on device manager(windows).  

Thanks for helping.

if it failed at user information,
disconnect the mifi, remove and reinsert the battery, power on the mifi but don't connect it to the PC
is the mifi able to boot fully or does it get stuck somewhere?

if it doesnt boot properly, try this firmware @ https://routerunlock.com/download-firmwa...universal/ and webui @ https://routerunlock.com/download-huawei...universal/

It shows huawei logo at boot (2/3 seconds) but after that, the screen stays dark (the router is on). At this moment if I connect the router to PC, on device manager it was unrecognized as I showed you in previous replies (1.PNG).

I try to install E5577Cs-603_Update_21.200.07.00.00 but it was not possible because my device is E5577Cs-321. Not 603.
I try too all this firmwares (mediafire.com/folder/ll9ieqqooyhy5/Documents#6n40kgnsl8d1x)  but the result is always the same Sad

there is still more firmwares you can try e.g https://routerunlock.com/download-firmar...universal/
you can check the list @ https://routerunlock.com/?s=5577 for more different firmwares you have tried
if the outcome is still the same, you might want to PM the OP if there is something you are missing after step 6
