OR

Extract the modem.img from the zip and do the following commands via fastboot

- fastboot devices

- fastboot flash modem_a modem.img
- fastboot flash modem_b modem.img
- fastboot reboot

Once booted, set your network mode to Global or WCDMA/LTE or a different mode depending on your geographical location.
You may dial *#*#4636#*#* then once in the testing app, click Phone information then scroll down to see the network modes.

Hope this can help with your network issues! Comment below if it fixes your network stability.

writing 'modem_a'...
FAILED (remote: Partition flashing is not allowed)
finished. total time: 1.889s

writing 'modem_b'...
FAILED (remote: Partition flashing is not allowed)
finished. total time: 1.888s

I think it's not a successful operation. Is it for bootloader locked state that's why?

Yes bootloader unlock was the reason for failed.
So below should be working flashing process,
- fastboot devices
- fastboot oem unlock
- fastboot flash modem_a modem.img
- fastboot flash modem_b modem.img
- fastboot oem lock
- fastboot reboot

Guys, try setting network mode to Global after flashing this. It might fix the fluctuations.

Type *#*#4636#*#* in your Dialer app then go to Phone information and look for network mode.

Thank you so much

Thank you.

I'm not sure if this actually does anything on later custom ROMs though?
Assuming they include the same files.

However, I did check with older custom ROMs, and I now have -95 to -101 dBm in signal when using 4G (LTE), so it's absolutely worth trying.

It's worth a try.

I'll update this whenever a fastboot ROM comes out per month. Hopefully it improves your network.
