----------------------------------------------------------------------------------------------------
1) On your UmiZero,open "Settings-WLAN-Advanced settings-WLAN MAC address" keep note of your "WLAN MAC address"
2) Download & Extract UmiZeroNvramWriter to your desktop.
3) Run DriverSetup inside "Driver" folder.
4) Install BIRDA_SN_STATION_MT6592.
5) Run BIRDA_SN_STATION_MT6592 and select:
ComPort: USB VCOM
TargetSelect: SmartPhone
Model: WCDMA
Click on "System Config" button.
In the opened window select "WIFI Mac adr" (leave empty "Wifi Addr Header").
In "Data Base" section locate&select:
MDDB_UMIZERO (for MD DB_1 )
APDB_UMIZERO (for AP DB )
(You can find them inside folder "DB" of the extracted UmiZeroNvramWriter.zip)
Click "OK"
Click "START" on the BirdA SN Writer window
Insert your previously copyed WiFi MAC ADDRESS without ":" and lowercase (Ex: 00:08:22:C4:8e:1B BECOME 000822c48e1b)
When the notification COM port searching and preloader handshake... appears,Unplug the the devices and turn it off, don’t press the power button, connect your phone and PC with USB wire.
Click "OK" and the process will start....
....if everything has gone in the right way you should see the "Write Result Indicator" turn to green....
Now you can disconnect your device and reboot it.
IMPORTANT:
After reboot delete the folder "data/nvram" (using a Root Explorer) and reboot again (it will be auto re-created with the new values)
VERY VERY IMPORTANT:
THIS TOOL WRITE THE VALUES IN THE NVRAM SECTION OF YOUR DEVICES...SO IF YOU HAVE A PREVIOUS TWRP/CWM BACKUP YOU WANT TO RESTORE,UNCHECK "NVRAM" PARTITION (or you'll overwrite it with the old/wrong/bugged values)
IF YOU ENCOUNTER PROBLEMS DURING THE PROCESS IT IS 99% DUE TO WRONG/CORRUPTED DRIVER...IN THIS CASE TRY INSTALLING THE ONES INSIDE "\Desktop\UmiZeroNvramWriter\Driver(AlternateVersion)" OR RE-RUN "DriverUninstall & DriverSetup" INSIDE "\Desktop\UmiZeroNvramWriter\Driver"
...that's all...

Can you please elaborate this line which mentioned ! .. its bit confusing to me
"When the notification COM port searching and preloader handshake... appears,Unplug the the devices and turn it off, don’t press the power button, connect your phone and PC with USB wire. "

Thank you for this tutorial, just what I need. Step 1 is to see what your current MAC address is and write it down. However my MAC adress changes with every factory reset I make. How do I know for sure what my hardware MAC address is?
Best regard, FoOtY

After you have Inserted your previously copyed WiFi MAC ADDRESS without ":" (Ex: 00:08:22:c4:8e:1b BECOME 000822c48e1b)and clicked "OK".............Connect your UmiZero "turned off" :laugh:

You don't need to know what is your "exact" mac address (it should be writed in factory....but they don't).
You can simply use one of the random ones generated from your phone(best way) or go to THIS SITE and get one..
Don't worry:there are BILLIONS of conbinations possible...

It happened to me me too(i don't know why) but the third time it worked.....
...another possible option is to do it with stock rom(to be honest i've done it some weeks ago and i dont remember if i was on EMUmI or Stock rom....)

I think you have done it in stock ROM ... not on EMUml ....
Becoz we cant find "Settings-About phone-Status" keep note of your "WLAN MAC address" - here in EMUml ..... its in stock ROM u find it ...
For EMUml we need to goto "settings-WLAN-Advanced settings-WLAN MAC address"

Ah thanks Arcatarc! So when I change the MAC address with your method it will stay even when I preform a wipe from the Android settings / CWM? How could UMI release it like this? My WiFi is so unstable

Hi Arcatarc,
I've the same problem, writing to nvram is ok, deleting folder is ok but still have random mac address whenever I on/off wifi.
Could you give offset in file where MAC is stored, I'll try to place correct address by hexedit.
Is it storred in wifi or wifi_custom?

Guys,
After two days I think, that I've found the solution - permanent
What is important:
- files: wifi & wifi_custom must have rights: r-- r-- r-- (see photo)
- owner & guid must be empty (see photo)
- need 2 apps: hex editor & es file explorer installed
- the most important thing is correct MAC ADDRESS, it must start with 000820XXXXXX use online generators like:
http://www.miniwebtool.com/mac-address-generator/
So, what we need to do:
1. Important - (Turn ON WIFI), delete files "WIFI" & "WIFI_custom" from folder "data/nvram/APCFG/APRDEB/" to have them recreated with correct owner & guid rights after restart.
2. Restart phone.
3. Turn off wifi.
4. Use hex editor to edit file or better mobileuncle tools (engineer mode ->(MTK)-> connectivity menu-> wifi ->nvram). Look at attached photos, You will need to insert own MAC address to file. You have two ways:
- by Mobileuncle under "Byte String Access" set
addr value "4"
length value 6
Press "Read", should show you some random generated mac address, delete it and place your new valid MAC Address & press "Write".
That should save your new mac, you can check if that was saved by pressing "Read", should show you your new mac address.
- by Hex editor (give it root rights in options) and open "WIFI" file, go to offset $4 and insert your new mac address & save file. (see photo)
5. We need to set correct rights on both files "WIFI" & "WIFI_custom". I've used "es files explorer" and set all only as Readable. Remember do this on both files. Don't change owner & guid rights, must be blank.
PS.
I've messing around quite long, so I hope that I wrote the steps in correct order. If that doesn't work, try to turn on wifi after saving new mac address, or restarting between some steps etc.
I've used mobileuncle but I know that some of you had problem, so I've wrote the hex editor way.

Alternative way

WiFi connectivity problem

Hi,
I’m from Portugal and I’ve bought a Mi5 some days ago.
I have a problem for which I don’t find any solution.
The phone came with a modified fake ROM from the Chinese store but was working fine.
I unlocked the phone and installed TWRP to flash other ROMs. I flashed MIUI 8 global stable and a custom ROM from Xiaomi.eu without any problem.
Everything was working fine with the phone but I noticed that a lot of files from prior fake ROM (the one from the Chinese store) remained in the phone. So I decided to swipe everything in TWRP (including system and internal storage) and flashed MIUI Global Stable ROM again.
From this point, I never again been able to connect to a WiFi network and the 2G, 3G LTE connection became very weak and instable. The phone scan the wifi network available without problem, but after introducing the password, it tries to connect and just shows “Saved”.
I tried a lot of stuff. Static IP, reboot router, change router channel, change router security settings, flash different ROM, tweak build.prop file, but the problem persist.
In the phone test menu, when I try to connect to a WiFi I see that the phone scan, connect, disconnect, scan, connect, disconnect…
Any help?
Do you think it’s Hardware related issue? Or phone firmware and driver problem?
I’ll be very grateful for any assistance.

Hello
Yesterday I got the phone and I have exactly the same situation. Tried the same things, also flashing RR Nougat, RR Marshmallow, MIUI 7 and 8. Wifi isn't working in any situation. Did you solve it? Anyone have some ideas with it?

try another ROM
Just try the ROM "cm-13.0-20161211-NIGHTLY-gemini" .
My mi5 had the same problem when I got it, so I try unlock, bootloader, new cm14 rom, even went to change sim card, cause can't access 4G, still no luck. Then I backed to official ROM, factory reset, still have wifi and 4G problem. Finally after try the cm13 ROM, every thing became fine. It took me 5 days to resolved it.
FYI, mi5 's wifi signal strength is poor than others as so many complain you can see on the miui forum.

Tried that CM build, still nothing. I found in dev tools option to debug WIFI, and all the time I have RSSI of -127, even if I'm literally 1m from source (also I tried many sources). I'm out if ideas. Also It's not reception problem, because original ROM (like OP, probably fake global MIUI) had WIFI working just fine for me.

I have exactly the same situation.
I'll try the ROM "cm-13.0-20161211-NIGHTLY-gemini".
Thanks!!!

Unfortunately, this ROM did not work for me either. :crying:
Any more help?
Thank you very much!!!

Try Xiaomi.eu 8.1.7.0 Nougat.
It's working for me, but my wifi wont connect in CM/ AOSP ROM

Hello friend, do you have the link for me to download this ROM?
Many thanks for helping.

I had the same problem, same symptoms.
I too flashed a new ROM and couldn't connect to any AP, I tried various ROMS, MIUI 7 & 8 and CM 13 & 14.1.
Though I think I found a solution (it worked for me ). I simply changed my MAC-adress and I was able to connect to my home WiFi.
I'm running CM 14.1-2016225-NIGHTLY-gemini on MI5.
This is what I did to fix my WiFi:
First prepare an new MAC-address. I personally don't know when a MAC-address is considered valid, so I just took one from an other device. I used the mac address of my previous mobile phone, which could connect to my router.
1. Disable WiFi.
3. Enable debugger settings (Setting>about Phone>Press build number repeatedly).
2. Enable root (Develepor settings>root access set to "Apps and ADB").
3. Open the file manager app.
4. Give the file manager app root access (menu>Settings(cog in lower left corner)>General settings>Access mode set this on "Root Access mode").
5. Now find the file root/etc/firmware/wlan/qca_cld/ and open wlan_mac.bin.
You should see something similar to:
Code:
Intf0MacAddress=XXXXXXXXXXXX
Intf1MacAddress=XXXXXXXXXXXX
END
6. Change the first to your new MAC-address, but first write down the old one, so you can change it back if this method doesn't work for you.
The last X of the next line should be a digit higher than the previous line. E.g:
Code:
Intf0MacAddress=957FDC328BF[B]4[/B]
Intf1MacAddress=957FDC328BF[B]5[/B]
END
(This MAC-address most likely won't work).
7. Save the file. You might need to press the save button a few times.
8. Check if the file has changed.
9. Check if you MAC-address has changed (Settings>WiFI>Configure-WIFI(cog in right upper corner)).
10. Enable WiFi.
I hope this works for everyone that has the same problem.

I'll try this procedure too, thank you very much Pekkuky.
I'll be back to talk if it fired, thanks for the help.

I tried to install the ROM that bajak85 suggested and it did not work for me, however I tried the procedure that pekkuky taught in ROM Xiaomi.eu 8.1.7.0 Nougat (ROM that bajak85 suggested) and it started to work, changing the MAC address worked for me too.
I did exactly as taught by Pekkuky and tried with another randomly generated MAC. That also worked.
Thank you all for the help and thank you very much Pekkuky, saved my life with this tip.

Hello, did you make sure that the MAC address was actually changed? In my case, a reboot was necessary for the modification to take effect.
I needed to forget the network and try again too, try this too, make sure the MAC has really changed and forget the wifi network and try again.
Good luck. :good::good:

Made an account to thank Pekkuky, because this worked for me. I also linked it on a couple of Xiaomi.EU posts about the same problem.

I had the same problem and this method really worked. I was angry af for 1 week, trying to solve this. Thank you very much Pekkuky

[VoLTE/VoWiFi][OP5/5T] for almost all carrier!

Hey!
I have found a way to activate VoLTE and VoWiFi for OnePlus 3/3T, 5/5T, 6 and 6T!
Please follow this Guide to Activate it to your Phone!

Greetings,
jamal2367

I'd like to let you know that this method also worked for me in Czech Republic for Vodafone. This guide probably works for most of the carriers in EU. Thanks!
Diese Methode hat auch in Tschechien funktioniert, ich kann nicht VoWiFi benutzen aber VoLTE funktioniert super. Wahrscheinlich funktioniert dieses Guide für alle Netzbetreiber in EU.

gonna try at ukrainian Vodafone.... when they will launch Volte

Worked. Germany and o2.

Why not sharing here, too?
Read something about EFS? Will it survuve, are there some modifications?
Thanks in advance.

It survives modem flashes and all. I'd write the whole procedure here but I'd need @jamal2367 permission to do so.

It worked! It woooorked
Many many endless thanks, Jamal!

Hello,
tried here in belgium, when i click on "activate" it does nothing and when i click on start, nothing too.. Is there a validation message at the end of the procedure or not? thx

Working with Vodafone Portugal! Can't test a call just yet, I don't know anyone with a VoLTE device, but the icon appears.

From what I read on the forum, it's just the Magisk module for root users or the toolkit procedure for the ones without.
It does help with some carriers, but not everywhere =(
Thanks anyway!

And you have to modify your EFS ...
Read the OP on Hubo, he has an spoiler at the end.

Danke! I couldn't find it because Google Translate breaks everything.
Btw, could you modify your phone? I'm on step 7, but when I select my device, it gives me an error: "Failed to select interface with provided ID, please make sure interface still exist".
I did install the drivers and the QPST 2.7.420, did the *#801# and "Serial" + "Full-port switch" and I also tried removing and adding the port inside QPST Configuration and running QPST Software Download as Administrator.
The device is also shown under Ports in Device Manager (Windows 10).
Nothing worked...
Thanks!

Had the same issue, I rebooted my PC and that worked

/* Disclaimer */
This is at your own risk.
I am not responsible for broken phones, lost IMEI numbers, damaged EFS partition, whatever.
First make a backup of the EFS partition via TWRP or ADB, and back it up to a safe place on your computer!
WARNING: The EFS partition contains unique data for your device that is necessary for the phone function of your device. If you lose them, no one can help you out. So make a backup. If something goes wrong, you can restore the backup and you will be back to its original state.
2. you go to your computer and install both.
Qualcomm QPST Diag x64 driver
QPST_2.7.420
Now connect your mobile phone to your computer via a "USB cable".
4. opens the phone app and enter this code *#801#.
Now a new menu appears and switches "Serial" and "Full-port switch" on.
Now you start the program: "QPST Software Download" and connect it to your device.
Go to the "MCFG_PDC" tab at the top and select your device under "Device:".
Right-click on "Oversea-Commercial_DS" and select "Sub0" and "Sub1" under "Deactivate".
Now click on "Oversea-Commercial_DS" again and click on "Remove" on the right.
Now restart the program and go to the tab "MCFG_PDC" and under "Device:" select your device again.
Now select "Telefonica_UK_Commercial", right click and select "SetSelectedConfig" "Sub0" and "Sub1".
12. click on "Telefonica_UK_Commercial" then right click on "Activate" and then on "Start" below
13. after you have done everything, restart the device!
After a successful restart, the "VoLTE or VoWiFi logo" should appear in the expanded status bar.
No wonder why you dial "Telefonica_UK_Commercial", works great in Germany with all providers!

I wonder if this has the potential to fix the 3G issues as well, as we're effectively changing the modem's default profile it seems.

No lucky =( What's the name of the device that appears for you under MCFG_PDC tab?
Thank you!

It should be a long string of characters, IIRC. The name is unique to every device afaik.

Did someone tried this with French network ?

Is there any way to enable this on aosp rom?

I don't think so. Most AOSP rom's are missing some APN's. Ask the Dev if he implements all Google AOSP APN's.

[GUIDE] Enable VoLTE/VoWiFi on LineageOS 17.1 for EU carriers Oneplus 6T

[GUIDE] Enable VoLTE + VoWiFi for German and other EU carriers on the Oneplus 6T running LineageOS 17.1

Watch your phone to accept the incoming connection from your computer.
Type:
Code:
su
and watch your phone again to accept root access.
Activate the Diagnostic Mode by typing:
Code:
setprop sys.usb.config diag,serial_cdev,serial_tty,rmnet_ipa,mass_storage,adb
Your phone will disconnect from adb, but thats ok.
4)
On your computer open "PDC" from the installed QPST application as admin.

This will open the Testing menu. Select the first entry "Phone information".
In the option "Select phone index" you can choose your sim card you want to get information about.
Then, press the three dotted menu in the upper right and select "IMS Service Status"
If it says "IMS Registration: Registered" everything is working fine. Depending on whether you are on WiFi or LTE, "Voice over LTE" or "Voice over WiFi" will be shown as "Available as well.
Enjoy!

Great work. I'm on Linux. What is this qpst and psd tools for exactly and is there a way to do the changes from Linux?

I'm on Linux too. Qpst is a USB Modem driver and PSD is a Tool to access and alter the modem firmware on the phone.
Unfortunately these will only run on Windows. I used VirtualBox and run Windows 7 (I bought a cheap license key some time ago) on it.

So none of these tools could be helpful?

Interesting, I didn't know these tools. Maybe it could work.

Thank you for the guide. Still, I think you have a typo:

There's a space preceding ',adb', and with blindly using this command something went wrong on my Windows PC. Had to restart. 'setprop' also supports only 2 arguments.
Another thing:

Remark:
I did not test it, yet. But you may have to repeat the procedure after every LineageOS update.

You should put that on top, maybe make it bold and set a bigger font. It looked like a tested and working method, I just blindly followed the instructions without questioning (also a mistake on my part).
Anyway, I followed the steps successfully but cannot see if VoLTE/VoWifi is functional as there is not indicator in LineageOS 17.1. If anyone knows a way, feel free to tell.
Thanks again.

Thank you for your reply.

You are right, It's a typo, I didn't notice. Fixed it.

The whole procedure was tested on my own phone. There was just one unclear thing, whether these changes survive an update of the LineageOS system. It does! So I removed this obsolet remark.

Yes, it's a pitty there's no indicator in the status bar. I've found another way to check functionality and added it to the guide.
Hope this make things more clearly.
Thx

Tried it on stock oos 10.3.6, and windows 10. Have swedish carrier Tre (Hallon).
Works great! Thanks for your guide! ?

Procedure fails on OP6 with LineageOS20, phone is not visible in PDC.

Hi,
Do exactly as described:
Download Settings Database Editor from playstore and open it
Look for hw_networkmode_preference and edit the stock value "9,6,2,1" to "11"
Restart the device
Open Settings Database Editor
Click on + Add new setting at the top
Type "hw_add_4g_only" (without " ") and press save changes
Type in your country code, example "502" Malaysia or "262" Germany. Press save changes
Type "hw_add_4g_only" (without " ") and press save changes (YES, REPEAT STEP 6)
Type in your country code, example "502" Malaysia or "262" for Germany and press save changes (YES, REPEAT STEP 7)
Restart the device and VOILA!
Now you have access to ALL network modes. Select "LTE" or "4G" for 4G only functionality.
Ex.: 234 (Three UK code)

I tried but it didn't work. Did yours work. Can you send a picture of your network modes after it worked
