[MENTION=8319869]lekhraj.gupta@gmail.com[/MENTION] please add adb after diag. copy and paste this: setprop.usb.config diag,adb

and let me know if it worked.

i will help you.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
I tried this command but it says file not found.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
tried where?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
shell
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
then you should install qualcomm and adb drivers. they wont work without them.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
Can I please get a link.

I already have minimal adb and fastboot installed. Also I think the qualcomm drivers are bundled with QPST so I haven't installed them separately.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
Thanks for your prompt and correct help.

I did 2 things: 1) Disable driver signature and 2) used command "setprop sys.usb.config diag,adb" and voila qpst was able to detect my phone and backup successfully completed.

Now while flashing the new file after clicking Install, getting error as screen shot attached. Please help.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
this action is very sensitive. i am working on this for months. and i can say that sometimes qpst version changing worked for me although it is working fine.

we should continue step by step.

you should use a good usb cable which has 8 pin. (data transfer cable)

i recommend to use you qpst 2.7 build 472 (i recommend everyone. it works great with kenzo)

you should install adb and qualcomm drivers

adb: http://xiaomitips.com/download/adb-setup-v1-4-3/

qualcomm: http://xiaomitips.com/download/qualcomm-qdloader-usb-drivers/

if although they were installed and you can not see phone as com diag port in device manager, uninstall drivers and install again.

[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
You can download adb driver from https://adb.clockworkmod.com/.

I tried and it worked for me. And also disable driver signature before processing.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
Its detected due to disabling driver signature.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
I think I should be first trying to get my device detected in diag mode in device manager and then I shall try QPST.

So, I have found the qualcomm drivers on the net and have installed them. I have already restarted before trying and although the drivers I used are digitally signed for Windows 10, I still have driver signature verification turned off.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
close qpst and run script again. they both can not work.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
I tried but same error. Even command prompt close automatically so fast, I can't read the error. I have to make a video and play in slow motion to get the error.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
maybe it is still working in background. for sure, reboot your pc and try again. As you say you successfully opened diag port, it must saw your phone. diag port is one way. can not connect 2 apps same time.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
Ok so I got it working by using the following commands in terminal:

setprop sys.usb.config diag,adb

setprop sys.usb.state diag,adb

setprop persist.sys.usb.config diag,adb
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
I tried after reboot PC as well as phone with driver signature disable.

After clicking Install it's asking for "Press any key to continue" and after few seconds command prompt closed automatically.

I checked the Install.cmd file and found that it is also not having the word ADB after diag. Do I have to add and try?

Below is full text from Install file:

just try to add
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
Voila... Yes after adding ,adb in install file, it worked. A very BIG thanks to you...:):good:

Now Airtel Volte is working on my phone. Just want to know when I will update ROM, I have to follow these step again or it will remain active.

I request [MENTION=8950490]amog787[/MENTION] sir to put ,adb in both place i.e. at First post and in Install file also, if required. Don't know about other user is also facing this or not.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
I have finally been able to complete the process and flash EFS on AEX. The VoLTE service hasn't been enabled yet though. Should I wait for some time for Airtel to activate VoLTE on this SIM or should it have been activated instantly.

Note: I have never used VoLTE on this SIM before.

Edit: Tried with another VoLTE enabled SIM and it works flawless. I guess I have to get VoLTE enabled on this SIM as well.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
Yes get it activated by Airtel on your number. Airtel and Voda is not activating volte by default.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] vinayak.s19:
Yes...The customer care chronicles.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] agritux:
I gave him the command with adb, but i think he forgot it.

If he wont put adb addition to command, i will edit op tomorrow. Good to hear that it is ok.

And Efs wont change unless you install any official or custom miui rom. Miui changes Efs and you need to flash Efs again. With other custom roms it is ok.

[Xiaomi Redmi Note 3 Guides, News, & Discussion] InfernoCoder11:
Guys, this hack really works and I have got Airtel VoLTE working on my phone now. I did face many problems while trying to get this to work. I thought of making a list of the problems I faced and how I solved them. Hope I could help someone.

Device not getting detected in QPST

Instead of running the command

setprop sys.usb.config diag

, I ran

setprop sys.usb.config diag,adb

and it got detected.

"Critical error. Value cannot be null." error

Before running INSTALL.cmd, open Magisk app and revoke root permissions to shell. Now run INSTALL.cmd, it should say something like "permission denied" and "Press any key to continue.....". Now, grant root permission to shell then press any key on your pc. It should start flashing. I tried changing usb ports, rebooting my phone and PC but this was the only way it would start flashing.

VoLTE not getting activated

I first tried putting another Airtel sim from another phone (on which VoLTE was working) in Kenzo and VoLTE was working in Kenzo also. So, I tried calling Airtel customer care. They did not solve the problem. Then I put my sim in another phone in which VoLTE is officially supported by Airtel. Now I called them again. Even then it did not start working. Finally, I sent them an e-mail and after 2 days VoLTE has started to work on my phone.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
Thanks for the detailed info... but wondering why Airtel is making nonsense thing by not enabling Volte automatically for all 4G SIM. Why customer have to call them and request for activation of Volte.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
U Should know that 4g and voice over 4g is purely based on internet and more organised.

All the list of compatible airtel volte supported devices is already listed in thier system.

When u insert particular sim card in ur phone ur 4g ISP will already will know which phone model u r using .

So only those phones like redmi note 4 and latest will automatically get volte which are officially listed in their system.

It is fully computerised and organised. Coz 4g protocol is fully based on internet IP and not outdated like circuit based 2g and 3g.

The reason why kenzo is not getting automatic volte coz their airtel system will show redmi note 3 as incompatible device with airtel volte.

So on ur request they need to manually enable for u to get volte.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
Thanks for great info... but even users using Airtel Volte supported handset, they have to call customer care to activate Volte. It's not getting activated by default. That is nonsense from Airtel. I faced this on my 2 Airtel sim and so many of my friends also.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] InfernoCoder11:
With officially supported Airtel VoLTE devices, it takes around a week for Airtel VoLTE to get activated, if you have never used VoLTE on that sim before (happened with me once). Unlike Jio which is essentially a 4G only VoLTE only operator, the other operators also have existing 3G and 2G systems for fallback in case 4G is not available in some location. I guess that for other operators, setting up VoLTE for your sim requires some additional work. That's why Airtel/Vodafone takes one week and for Jio, VoLTE works instantly. It seems calling/e-mailing Airtel only speeds up the VoLTE setting up process. Airtel may not be doing this by default because for them there's no point in doing it for those who don't have VoLTE supported devices and for Jio they have no choice because they are a VoLTE only operator.

In our case, I think we should thank Airtel (and the devs who made this possible, of course) because they are letting us use VoLTE on a device which is not officially supported by them.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Mad1446:
I can confirm that the VoLTE patch also works outside of India. My carrier is O2 from UK. Many thanks to those who worked on this! If you want screenshots I can show it.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Notam:
Do we have to call Airtel cc to get VoLTE activated on our sim. Mine is a 4G sim.

I had BTLG earlier and had flashed the VoLTE patch, them i flashed the PE for testing purpose. Now i am back to BTLG, so do I have to flash the VoLTE patch again
[Xiaomi Redmi Note 3 Guides, News, & Discussion] lekhraj.gupta@gmail.com:
First check VoLte on another phone. If not activated call airtel cc. After activation try in kenzo.

Please suggest
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Saikat0511:
Thanks a lot [MENTION=8950490]amog787[/MENTION]. So I performed the steps on Havoc OS 2.5 pie and here's my experience:

1) EFS backup was stuck on 99% for like a hour with no error and even the status was shown "MEMORY BACKUP COMPLETE". So I just exit the program and proceeded to flashing.

2) Running install.cmd gave me error "resource in use". So I used download version 2 and it worked.

3) After initial reboot VoLTE did not worked. I swapped the sim to slot 1 and rebooted several times over and over (three times to be specific) and IT WORKED!!! no customer care call was needed for me... Confirmed functionality by video calling over sim network. Screenshots attached ...
[Xiaomi Redmi Note 3 Guides, News, & Discussion] ayamstr:
[MENTION=8950490]amog787[/MENTION] can you please share the method you used to extract volte files and made this patch possible so Volte can be enabled on other devices as well?

You can clean flash any custom ROM, but if still you don't get VoLTE if it was there before, clean flash latest MIUI stable build and then move to any ROM of your choice.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
BEFORE TRYING THIS HACK U SHOULD TAKE EFS BACKUP IN TWRP FOR SAFETY.

u need to Restore Efs backup using TWRP.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] HiQual:
Thanks ...

I followed the full procedure in the first post and made a backup using QPST before running the hack install.

My question should have been more specific and say - is it suffiicent to simply use QPST restore function - or are additional other steps required ? anybody.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
Just restore.

Did you do this hack or did it just started showing volte?

---------- Post added at 08:23 PM ---------- Previous post was at 08:20 PM ----------

Why there isn't any easy method to do this?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
Coz Volte is related Efs partition. U cant mess with EFS. else u will loose IMEI number.

So be careful. Take backup of EFS before overwriting new EFS volte hack.

Or Use Jio Sim.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] ssachu94:
Is taking backup of EFS Partition using TWRP is enough?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Black_Stark:
U can take backup both ways. Also using QPST tool

[Xiaomi Redmi Note 3 Guides, News, & Discussion] PRemBh0i:
Bro you f-ed up real bad. Did you use QPST to take the backup of EFS partition? If so then specify which version or try another one (old or new) whichever works for you. Rip in peace tho.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] HiQual:
Apparently you can also restore your EFS by simply flashing the firmware in TWRP - not the ROM - just the firmware.

Recommended to use MIUI global stable "fw_kenzo_miui_HMNote3ProGlobal_V10.2.1.0.MHOMIXM_36c0f5ded3_6.0.zip" - for KENZO only
[Xiaomi Redmi Note 3 Guides, News, & Discussion] WarriorMax:
OK will try this also. Thanks

Just one doubt if you guys can help me. I'm able to enter Fastboot mode & my MIFlash tool also detects my phone. So now do I need to enter EDL mode also by running some script for flashing stock rom. I mean I wanted to know what is use of EDL mode when I can directly flash the fastboot rom thru MIflash?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] HiQual:
MiFlash needs the phone in EDL mode to flash the fastboot version of the ROM.

I do not think you can use MiFlash to flash fastboot ROM if phone is not first put into EDL mode.

I hope I understood your question.

PS do "flash all" for restore of EFS
[Xiaomi Redmi Note 3 Guides, News, & Discussion] WarriorMax:
Actually from what I read is that if my bootloader is locked only then I need edl mode. Since mine is officially unlocked can I directly flash the stock rom?
[Xiaomi Redmi Note 3 Guides, News, & Discussion] amn1987:
If bootloader is officially unlocked you can use Mi Flash tool to flash Fastboot ROM when device is in fastboot mode. Just make sure NOT to use "clean all and lock" as it will lock the bootloader again. Ofc you can unlock it again but best to avoid it. EDL mode is necessary when for whatsoever reason fastboot isn't accessible. I don't think Mi Flash can be used in EDL mode.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] HiQual:
Mea culpa WarriorMax

This reply is correct and mine was wrong - I had forgotten about fastboot mode and confused it with EDL.

Does it feel smooth? I'm currently deciding if I should buy this phone or the Mate 20 lite (I'm buying with Tre at the same price), I really like the screen and the camera but the SoC is slower on the A7. As long as it is a smooth UI I'll buy this one, since I'm not that interested in graphics demanding games and CPU intensive apps, I just need it to be usable without lags and random freezes.
[Samsung Galaxy A7 (2018) Guides, News, & Discussio] Daniel00tm:
Don't buy the Mate 20, i bought one before getting the A7, the screen in the Mate 20 is really bad, has one of the grey "ish" blacks I've seen on any recent phones, my unit also had a problem with hot pixels that were only noticeable on black colors in very dark environments
[Samsung Galaxy A7 (2018) Guides, News, & Discussio] ecavicc:
Is it really that bad? I mean, it's an LCD, obviously OLED screens are better, but I was told and I found online that it's a fairly good LCD for a mid-range phone. Also, I don't really mind the screen, I just need a smooth system, and from experience I know Samsung ones can be quite heavy. On the other hand, after two years and a half of EMUI I'd like something that looks newer, and Huawei has recently stopped providing bootloader codes for free. That said, I'll still keep EMUI if it means that it's smoother.
