Lenovo Z2 Plus/ZUK Z2 Plus Baseband Update Guide(Keeping Bootloader Unlocked)

Q. Whats Baseband?
Baseband in laymans terms refers to the radio drivers or blobs of the device.
Many users have complained of their bootloader getting relocked after updating their baseband through a zip file through TWRP or even through fastboot
This guide is for updating the baseband through fastboot WITHOUT RELOCKING THE BOOTLOADER
Using this Method Wont Touch Your Bootloader Keeping it AS IT IS (In the same state as without flashing this baseband)
Many a times after updating baseband or restoring firmware backup through TWRP we cant hear sound or the reciever cant hear us during calls OR sometimes in your custom ROM or sometimes even in latest ZUI you cant get VOLTE working despite all correct APN settings
If you face this problem then updating your Baseband will Solve the Problem Most Of the Times
DO NOT USE THIS ON MARSHMALLOW STOCK ROM OR MARSHMALLOW BASED CUSTOM ROMS IT WILL CAUSE PROBLEMS
USE THIS ON NOUGAT STOCK ROM OR NOUGAT/OREO BASED CUSTOM ROMS
CAN BE USED WITH LOCKED BOOTLOADER ON STOCK ROMS
If TWRP is installed then take a backup of your efs partitiom
Using This Tool Will update the Baseband to M8996FAAAANAZM-1.76387.1.92759.1 (Latest Nougat Baseband)
1.First download the tool from this link https://drive.google.com/file/d/0B2CgYqnPbCh_Q2N0Vmd1d00ySFk/view
2.Download and unpack archive
3.Load the phone into fastboot mode.
4.Connect to PC.
5.In the folder with the unpacked package: Run cmd and then flash_radios.bat - follow instruction on screen.
6.Reboot.
For Installation without PC flash this zip file by davide which i have edited so that it doesnt lock the bootloader or change the splash image, using custom recovery.

If u don't need volte than u can dirty flash baseband on any rom naugat or oreo.
But i think volte is gone because baseband is being flashed with some errors. So it can cause problems like signal fluctuations and wifi instability..

For those who getting volte and calling voice bugs...
Flash deodex zui 2.5 indian ..
How i solve my prob
Basically i try oxygen os marshmallow based rom(which degrade my baseband to a mm one) and then i restore my naugat twrp backup....then the voice bug happen.....
Then i flash the latest indian baseband from zuk fans forum....on my custom naugat rom(viper os)
After flashing voice bugs gone...but my volte stops working....
Then i flash deodex stock zui 2.5 indian and enable volte(volte works at this stage) and then flash my custom naugat again ...and everything is fine
SO THE STEPS ARE
1..Flash baseband ..then check if everything works fine or not(basically check ur volte and voice call)
If not then follow step 2
2..Flash stock zui2.5 indian....after zui flashing check everything will be working great ..(don't forget to enable volte in stock)
3...Now its upon u whether to flah custom or not
..................ENJOY.................
NOTE: MY DATA IS SAFE...BY ABOVE STEPS U WILL NOT LOOSE UR DATA
M giving some reference link down below hope i helped u

If you already flashed the baseband then you don't need to flash it again, if volte doesn't work for you then you can flash baseband and clear modemst1 and 2 yourself and clean flash rom/gapps/magisk.

Thanx, I'll do like you said.
I occasionally loose signal bars, then I can't receive and send calls. It's just for few seconds, but it's still annoying coz I have too much calls with partners on my work.

Works like charm!
I'm running AOSP Extended 5.0 Latest Build by @davidevinavil . I just downloaded, unpacked archive, rebooted phone in fastboot mode, connected to my PC (USB 2.0), and ran .bat file as administrator, disconnected phone and restart. Everything is working. Thank you dev for this guide! :good: PS. Not a Jio user so no idea if VoLTE works. WiFi, 4G, Calls work flawless.

UPDATE. I'm using Vodafone (Mumbai Suburbs) and after updating baseband, I'm getting faster webpage loading speeds than before.

This can be flashed on locked bootloader of nougat stock roms?

For Changing Baseband Without PC Flash this zip by davide which I have edited so that it wont relock the bootloader or change the splash image. Baseband version 2.0
https://drive.google.com/file/d/1mHdf2kc0ARpRO6kxAKiI3dotAVY0TJdM/view?usp=drivesdk

calling issues: receiver cant able to hear me properly
First i flashed stock (nougat) ZUI_2.5.104_ST (Indian) volte was working fine calling was perfect on both sims.
Then i flashed aex 4.6 i checked the baseband it was version 1.7 (previously it was 1.6).
Volte is not showing then i have to manually add the apn then volte was there.
But sim1 voice clarity is not perfect receiver cant able to hear me....sim2 working loud & clear
Please suggest to me some method to resolve this

Redmi Note 7 128gb

Hi all,
I have ordered a Xiaomi Redmi Note 7 128gb.
In the description of this section is the Info, there is only a 32gb and a 64gb Version of this Phone. Does the Roms and TWRP work with the 128gb version too?
I ordered here: https://www.ebay.de/itm/Xiaomi-Redm...hash=item5d87e41195:m:mnXTK9QqBL5-gxmHyy9jb3g
Thanks and have a nice day.

IMHO.. As long as your phone code name "Lavender" then its works and youre welcome to try.

Yes it will.

Yes , mine also 128gb

Yes I have, oddly with it it looses baseband I had to restore modem from a backup, I checked my device in Xiaomi page and it's listed has the Global International version so I dont't know why the fastboot global rom that I flashed made my phone loose that. I have MIUI Global 10.3.6.0 (PFGMIXM).
All is working as it should after restoring the modem data.

Flash orange recovery and try again ... If this doesn't work, download the Rom again and try it.
I have the same device as you and I have tried Havoc OS, miui.eu (both stable and beta) and MiuiMix without any problem... ?

I'm confused now what device do you have? You said j500f in your original post and none of them ROMs are available for j500f.
Also j500f stock rom stops at marshmallow 6.0.1
If it is j500f I'm surprised your device still works after flashing all those wrong files
So is it j500f or j530f?
Make sure you have the exact files downloaded for your specific device or you will have sim issues at the very least
J500 is 2015 model
J530 is 2017 model
Completely different SoC so the software is not compatible

I have a galaxy note 4 exynos n910u (treltexx) with stock rom (6.0) everything works fine so i decided to install custom rom. First it was hard to find the rom for it after i found few i flashed one.
RR with twrp 3.3 after flashing phone was working like usual but when i interted the sim card it did not detect it so i tought it might be the rom what causing it then i flashed the stock with odin and sim was working fine so i flashed lineage same issue again evwn then i tought it was rom but no matter rom i try sim was not getting detected (exept stock) .
Thing i notice was there was no imei number after dialing *#06#*
So i found the new rom Note 7FE edition android 7 i gave it a try same thing no sim detected but this time i was getting IMEI number
Also my phone is N910U and showed Spark nz logo at boot and i'm in india but sim works fine on stock get 4g and everything and also when i install any rom it say N910C ony Note 7FE edition one said N910U
Is there any way to fix this issue

I wrote to you on the telegram channel also - the 910U has a weird modem (Intel) which has issues with the RIL (radio layer interface).
Also the developer has no phone note 4 910U so that he can test it and get logs to see errors.
As for all the peeps with this model - "It is what it is" - deal with it.

I'm not sure if this will work but you have a backup of your stock roms modem partition you could yry dirty flashing it to your custom rom. You could also use a root file manager and copy your stock roms csc files and place the in a flashable .zip and dirty flash that to your custom rom.
