No IMEI, no Wifi? Here is the solution.

[oz42]

My XT1900-7 had lost its IMEIs and Wifi connections, even after factory reset.

The solution:

Get XT1900-1_PAYTON_FI_9.0_PPWS29.69-39-2-4_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip from lolinet
if you are booting from slot _b, then go to fastboot and flash modem from this FI ROM:

fastboot flash modem_b NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot

It worked! Well, now I can connect to 4G and actually set my device, but still not able to get wifi connections tho.

EDIT: I decided to flash the entire rom you the OP mentioned and now I'm full online with mobile data and wifi!! Thanks

Just saw your answer now. I couldn't make it so far. I did not quite understand your answer. I am Brazilian and I use translator.
I have the manager unlocked. However, it does not accept any adb commands.

If you can help me, I am grateful!

I had an issue where network would completely drop from time to time, the icon would show an X, however, wifi and everything else worked. I followed OP directions with the modem from XT1900-1_PAYTON_FI_9.0_PPWS29.69-39-6-4_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip and everything is fine now. Thank you so much.


back story:
Device: XT1900-1

I following these directions on this thread to install the latest stock/factory firmware mentioned above

I then installed lineageOS with magisk and started encountering the issue.

Yo necesito ayuda, ya reinstale la rom stock y me da acceso al wifi, pero sigo sin poder hacer funcionar la conectividad 4G, puse los comandos que se mencionan y lo que hacen es borrarme el IMEI, vuelvo a reinstalar la stock y sigue igual sin darme señal de RED MOVIL.

Como haces para poner el IMEI de nuevo?

hello guys, all these problems are solved by flashing the correct firmware without any magic just that, via adb with the commands and the latest correct firmware, everything comes back: wi-fi, sim card everything, they must be fixed if the device is xt1900-1, 2 4 etc and if it is retail, eu, us, fi etc and voila, greetings

For those with retail US build.
The way to downgrade to Oreo with working WiFi and Mobile is to do the following
0. It goes without saying that you should make a backup copy of the EFS, Persist etc.
1. Restore the Pie 9.0 Stock PAYTON_RETAIL_9.0_PPW29.69-40-4_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
You can do the flash all, and boot to the new system with the screen that shows it can discover nearby Wireless stations (if it is still searching, it means the modem settings are still wrong)
2. Restore the 8.1 Oreo by skipping out the following
:: fastboot flash modem_a NON-HLOS.bin
:: fastboot flash fsg_a fsg.mbn
:: fastboot erase modemst1
:: fastboot erase modemst2
:: fastboot flash bluetooth_a BTFM.bin
Got the 8.1 up and running with working WiFi/Mobile.
