Hi Folks,

When in Xiaomi launched Redmi Note 4(Mido) in India, at that time Jio was one supporting 4G all over India, hence to cut cost on Licensing Xiaomi approached to Cut LTE band Support in Mido. It launched with support of Band 3, 5 & 40, unfortunately with Time More carriers came with Band 1 & 8. Unfortunately Xiaomi didn't show interest in Unlocking Bands via Firmware update with Lol reason of Hardware Limitations.

But, I have Good News..

I am able to unlock those additional Bands using QXDM tool. It was simple and I tested myself in Different Circle with Carriers utilising Those bands.

When, I started working on Unlocking bands, I got to know in WCDMA, These Band 1 and 8 were enabled by default but LTE wasn't configured to use it. I researched further and came to conclusion, RF Module is same in case of WCDMA(3G) and LTE(4G), no it was just Firmware which wasn't configured to support it. So Basically, It had to support those bands and I went on with my idea and conclusion.

Things required are-

1. QPST Tool

2. QXDM Tool

3. LTE Band Calculator

4. Phone with Working USB Port :D

5. PC with Windows and all drivers up to date.

First step is to enable Diagnostic mode. If U are on MIUI it's easy to enable. just punch *#*#717717#*#* and You will be greeted with Diag Mode Enabled toast notification. And If are on Custom ROM, then U MUST BE ROOTED. Enable USB Debugging > Connect to PC > Now Open ADB Command Window(Hope U are familiar with this) > type adb devices (Device list will show) > adb shell > su (grant Root permission from phone) > setprop sys.usb.config diag,adb

However U can Use Terminal Emulator app too. Type su (grant root permission) > setprop sys.usb.config diag,adb

PS- Those ADB and Emulator commands may fail to enable Diag Port in Custom ROMs. If fails, then option is to flash MIUI and Use USSD code.

Now in device manager, U will see Qualcomm HS-USB Device with COM Port Number. If Windows is Updated and connected to Internet, Driver will get installed automatically.

Download and install QPST Tool, and QXDM Tool. Now Launch QXDM Tool.

1. Go to Options > Communication > There it will show COM Ports, Choose port and Now Change Target Port to your COM Port.

2. Click on View > New > Common > NV Browser

3. Now Click on Category Filter > Select LTE > Edit 06828 LTE BC Config & 06829 LTE BC Config DIV

4. Put phone in Airplane Mode before editing. BTW Note down default Values. To Read Values, just Click on 06828, in window

underneath select First one and Click on Read button and do same for 06829.

5. Open LTE calculator in Phone, choose Bands U want to enable. To Be specific choose Band 1, 3, 5, 8 & 40.

6. Edit first line of 06828 and 06829 respectively. To Edit, Just double click on Input and enter same Number that U see in LTE

Calculator app and now click on Write.

7. Wait for some time, now disconnect Cable and Reboot device and disable Airplane Mode.

Voila U have enabled Those Additional important Bands.

I have checked Airtel and BSNL 4G using Band 1 and 8 in AP and Jharkhand Bihar, WB, Kolkata and many more.

Attaching Screenshots for all.

[MENTION=5656495]hoshang.govil12[/MENTION] Do i take a backup of EFS to keep the unlocked bands safe? Or are they unlocked permanently. Flash addict here.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] hoshang.govil12:
U can take QCN back-up and keep it safe. BTW Once u edit QCN aka With this method once it's unlocked then No matter U flash Fastboot ROM or firmware or Anything, It will remain unlocked.

You're wrong.Mido comes with This LTE band 1(2100), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300).No need to unlock.

[Xiaomi Redmi Note 4 Guides, News, & Discussion] Ruvy:
Indian variant of Redmi Note 4 only comes with 3(1800), 5(850) and 40(2300). Global variant has all those above mentioned bands out of the box.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] ThanveerAliSayed:
It just show lte+ if your mido is indian. If you look on network signal guru. It still be using single Carrier. We can see clearly that ul_ca off tag in it. Indian mido's antenna don't support ca. If you have the global Variant you will have ca(lte +) and these extra bands as factory default

It kinda did work and also kinda worked. (Using BSNL 4G)

After following your process I used Network Signal Guru.apk to check if it was unlocked, and it shows those missing networks :laugh: . But when I choose LTE in Mobile Networks the network won't show, it remains blank :( . I thought it might be network issue. So I inserted the sim in my other phone Nokia 3.1 and it was showing 4G sign. :confused::confused::confused:
[Xiaomi Redmi Note 4 Guides, News, & Discussion] Nandans Debnaths:
I m using bsnl 4g. I tried and I unlocked B1. I checked with Network_Signal_Guru.apk. But unfortunately it didn't worked. So I thought it might be network issue so i inserted my sim on nokia 3.1 and their it shows 4g. But on my phone when I turn on LTE on Mobile Network section on settings, the network remains blank. I have read many threads and community pages where all mido users says that it worked for them. But why is it not working for me?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] hoshang.govil12:
Check in SIM 2 too. But Once Insert Jio SIM and reboot and then Insert BSNL in SIM 2. Or have U tried Factory Reset?

as a wifi user, does it benefit me by unlocking more bands?

What happen if you unlock all bands?

What if you unlock all 44 bands?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] hoshang.govil12:
Cellular bands and Wifi bands are different so it won't benefit You. :)
[Xiaomi Redmi Note 4 Guides, News, & Discussion] hoshang.govil12:
See, there are hardware limitations over unlocking Bands and using it properly. On Software side, We can unlock every band but not all band will work as hardware won't be supporting. :o

Hay friend, I need your help

I unlocked bands after carefully following your instructions, and I checked it in network signal guru app for confirmation, but now LTE on SIM 1 is not working, it is showing no service, then I placed same sim on SIM 2 port and LTE working fine. 2g,3g working on Sim 1 but not LTE, please help me resolve this issue

4G works but volte feature not working

Thanks your solution has worked perfectly for me but the volte feature is not working. I use bsnl sim card and I live in gujarat where I believe lte band 1 (2100) is available for bsnl network. After implementing your instructions the internet became 4G and i got data at 4G speed but when i call to anyone i can see at carrier name written as " BSNL Mobile 4G" becomes only "BSNL Mobile" so i had a doubt when i called to someone or being called by someone the network switches to 2G mode.

My doubts where confirmed because whenever there is an active call the data stops and there is no Internet connectivity and as soon as call ends the data gets connected again.

So the data works but the volte/calling on 4G network is still not working.

So is there a way to solve this?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] nivethjunnithan:
actually BSNl is yet to roll out volte services. Right now selected areas have 4G and volte is not included. So, its obvious that network will switch to 2G during call.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] ntwrld:
I had thought about it that may be in my state/service circle volte services may not be available so I called customer care executive and they told me that volte is active in my area.

Further my brother has sim card of same service provider (bsnl) and he is having volte calls although his device is different than mine. That is why I asked why I am not having volte feature in my device. Whether I need to take some additional steps?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] nivethjunnithan:
BSNL released volte in my are on feb 2020. After unlocking B1 I was able to use 4G volte services without any break.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] ntwrld:
I don't know the exact date when volte services were released in my state but I know they are released in my state (gujarat). Since the device you use is also redmi note 4 like mine and you also unlocked B1 like i did yet i still don't have volte feature available to my device then there must be something wrong that i am missing. Guess i have to keep looking.

[OnePlus 3T Questions & Answers] Dj_Fex:
Hi

I just discovered that my phone's /data (and /cache) partitions (f2fs filesystem) seem to have gotten corrupted.

my suspicion is that it didn't shutdown safely (powerloss during shutdown, maybe the battery was already emptier than the os thought it was, starting the shutdown then increased the power usage)

The battery is less than a year old. (official replacement, not done by myself)

I didn't connect my 3T to power last night (forgot about it)

I connected it to power the next morning and went to eat breakfast, when I came back it was booted up. It still recognized my fingerprint and last app sessions still have screenshots from my apps. The home screen background is still the same. My apps are all still there as far as I can see.

But: all the data is gone. My apps start like I installed them fresh from the store and opening my file manager none of my files are there any more. only 15gb of 128gb used up. (it was closer to 100gb)

Upon noticing this I immediatly went to twrp (3.2.3-10) to use it's repair feature for the partition. -> Error 139

I did the same for my /cache partition and got the same error so I suspect it got corrupted as well.

I'm running Havoc OS 2.4, Android 9.0 (didn't get around to update it and it ran smooth without any major issues for months)

Is there any way for me to backup what is still there (maybe even sector copy (dd))?

Is it possible to repair such an image in Linux or recover some of the files from it?

Is it possible that a newer twrp version actually still can repair my /data partition?

Or is all hope lost? Did my smartphone automatically reformat /data? or has it maybe not touched the partition but cannot use it correctly?

What happens in this case on Android? Would've been nicer (for me) to run into a bootloop instead so I can figure out what's going on, before any hope is lost.

I'm pretty sure encryption was turned off due to magisk/root.

Once I set up the smartphone again I'll switch ext4. I currently blame f2fs but I'm not sure.

I have backups of the important data that was on my smartphone, but if there is any way, it would be nice to recover the rest (images, videos in original resolution etc.)

:fingers-crossed:

If anyone could contribute ways for me to look into this or show me how to proceed, I would be very greatful.

and maybe it's not even f2fs's fault after all.

Regards

EDIT:

in twrp's file manager the file system looks the same btw. (/storage or /sdcard look like factory default)

EDIT2:

I managed to create an .img file from my userdata partition by using the adb command from twrp's adb shell

I hope that will help

I'll try https://www.forensicfocus.com/Forums/viewtopic/t=17133/ once it finished transfering the img file

Hello.

I recently updated my phone to android 10 and now my VoWifi and VoLTE is not working. It worked before but I had to go through the logkit to turn it on.

The settings in the logkit was gone with the latest update and I install a new logkit and turn everything on again, but its like its not activating the VoWifi and VoLTE.

Any ideas?

After updating to A10 (10.3.0) I no longer have the options to enable the switches (can be fixed with magisk module), but *#801# no longes works. Because I cannot enable Serial and Full-port switch, I also cannot use Qualcomm PDC. Does 801 work for you, or are you using another method?

Edit: never mind, figured it out. Had to install engineering mode app! All is good.
[OnePlus 6T  Questions & Answers] Nando14sunny:
Can you share the apk ?:)

And did it work to enable voLTE and VoWifi again?
[OnePlus 6T  Questions & Answers] efex:
First off, I replaced the new OEMLogKit with an older version, to be able to turn on voLTE/VoWifi witches in *#800#.

-OR-

Use a magisk module to make the switches available, I think I used this one for test purposes and it worked as intended.

To be able to use *#801# (serial), install EnrineeringMode apk, I used this one from APK mirror.

After this is done you can simply use Qualcomm PDC tool to change profile just like in Pie. :good:

When its done it's safe to uninstall EngineeringMode apk again.

EDIT: Yes, VoLTE and ViWifi works great! In my case I use the profile for H3G Denmark Commercial, but yeah.. What profile to use is operator dependant.
[OnePlus 6T  Questions & Answers] Nando14sunny:
wow perfect! I will try it tomorrow :) Thank you!
[OnePlus 6T  Questions & Answers] Nando14sunny:
Okay i tried to do it ^^ but if i type *#801# and then on serial, the app simply crashes and doesnt change "serial" to on :l
[OnePlus 6T  Questions & Answers] efex:
Yeah one of the options crashed the app, but you don't need that option enabled. I believe I just turned on the third box and then the first. I'm not sure which options are required, but that did it for me.
[OnePlus 6T  Questions & Answers] kischde:
Confirmed - just activated it the way you described. A big thanks, mate!!

- install old logkit and engineer mode app

- dial *#800# - activate VoWiFi and/or VoLTE

- activate switches in Settings/SIM & network

- dial *#801# - activate 'Full-port switch' (activating 'Serial' crashes the app but it is NOT necessary for the procedure to proceed!)

- as already known deactivate Sub0 and Sub1 in Overseas-blahblah and remove it afterwards; then activate Sub0 and Sub1 in H3G-Denmark and set it as active

- enjoy calls through your WiFi again :)

I'm not sure but probably flashing the Q supported twrp when you're on pie won't work. If that happens with you,

local upgrade would work and then you can flash Q TWRP by mauron using fastboot:

fastboot flash boot twrp.img

-Reboot to system

-It will open up TWRP, flash 10.3.0 zip file again

-Flash bluspark latest twrp if you wish to

-Reboot to recovery

-Flash Magisk 20.1

Done

Just flashed the new bluspark via the old TWRP and everything is fine except that i lost root.

I got root back by first flashing the magisk-uninstaller zip file and after that magisk 20.2
