Radio Modem / Basebands for ZUK Z2 Pro only

[weimerd]

Hi there,

I want to share the available RadioModems and baseband collection with you.

All credits to @crisps

-----------------------------------------------------------------
For all lazy readers that just want to get a good baseband:
After several tests from my side and verifying with other users here is my SUUGESTED BASEBAND for all Roms:

Radio Modem Full Version 4.0.247ST:
https://mega.nz/#!BYRiwYyA!1KU2-2Ovq2yB9RvaXCv95EFt_2aGNaziQ8Qka7R0ab4

You may use others as well. This is the most stable yet with less compatibility problems. Feel free to take another version. It is a suggestion only.
-----------------------------------------------------------------

I will update this thread when receiving new RadioModems/basebands.

Take care, all are to be used at your own risk, neither me or @crisps will be responsible for any damage.

I tested all without any problems.

No wipes necessary after flashing.
Flash with twrp.
I used latest official twrp and RedWolf Twrp for testing

No difference in basband version shown in system so don't get confused. In system you will always see the same baseband version. This is normal even if there are changes made between the versions according to changelogs of ZUI updates. There are even more changes in RadioModem (WiFi, Bluetoooth etc.). But changelogs from ZUK are not really detailled

-------------------------------

TroubleShooting:

Problem: After reboot your phone requires your usual pin on lock screen. But even when typing correct pin it will switch back to lock screen.

Solution: Reboot to twrp.
In twrp start file explorer (find it under advanced)
In folder data/system delete all files beginning with "locksetting". Usually one to three files.
Reboot. After reboot no pin is necessary, you need to re-setup again.

Problem: I get no LTE / 4G signal anymore. HELP!

Solution: Thanks to @vickdu31 and @juyer there is the following mini guide:

- Download 3.5 latest baseband from this post
- flash it with twrp.
- Extract .zip of baseband
- Reboot to fastboot

fastboot -i 0x2b4c flash modem NON-HLOS.bin (this file is from .zip baseband)
fastboot -i 0x2b4c erase modemst1
fastboot -i 0x2b4c erase modemst2
fastboot -i 0x2b4c reboot

LTE working instantly.

Enjoy mates

So can this Radio Modem / Basebands inprove 4G signal to get a better performacne?

 

[weimerd]

It can help you if you experience problems with connections like wifi, 4G or bluetooth.
And it can help you installing custom roms.

Most of the Android 7.1.2 based custom roms need a baseband of ZUI 2.5.xxx and upwards.

CustomRoms based on Android 6.0.1 need a baseband of ZUI 2.3.xxx

And finally with that basebands we all can participate on the improvements ZUK did.

Hi,

I was trying to Flash lineage OS 14, but ended up with the "perma blue LED crash" while connecting to Wifi.

Is there a guide how to update baseband on ZUK Z2 Pro?

 

[weimerd]

download the baseband zip. Flash it with twrp. Easy.

 

[GargoyleTGA]

I flashed the Radio Modem Full Version 3.1.194 but the baseband number is still in the settings. It is normal?

read mate, READ!

 

[weimerd]

updated 1st post with baseband of 3.5.204 DEV version.

And added full version of 2.5.462.

Thanks @crisps

 

[Nickkal]

i have clean installed lineage 14.1 after wiping system cache data and dalvik cache, do i have to flash the latest basebands?will i notice any difference?

 

[weimerd]

you dont have to

Usually basebands are flashed if there is an existing problem for you which may be solved by flashing a baseband.

Android 7 based CustomRoms usually need a baseband from ZUI 2.5 upwards.

Android 6 based CustomRoms usually need a baseband from ZUI 2.3

Some reported that baseband of 3.1 made connection reaction of phones faster. I dont know if it is a psychological thing. For me it feels faster as well.

So in conclusion: If you dont experience problems you dont need to flash baseband.

If your Rom is crashing with black screen and blue led flashing baseband of 3.1 may solve that.

Hope I could help you

Merry Christmas!

please read 1st post again

baseband version in about-screen is always the same, even if versions are really different bezween ZUI versions.

 

[weimerd]

added 3.1.218 in first post.

So I'm a little confused. You're saying that flashing the 'new' baseband won't change the baseband version number in the about screen, but it will make changes 'under the hood'? Did they forget to change the version numbers with the baseband updates?

I don't know the reason of ZUK not to change the baseband version number. They're Chinese

But according to ZUKs own changelogs there are changes

Especially Wifi and Bluetooth issues are handled as well as some 4G issues.

You can use the basebands or not. It's up to you. If you don't experience problems you dont need to flash.

 

[dimitar.petrunov]

Is it possible to go back to an earlier version by reflashing it?
