Yes i had the same problem. It will persist untill xiaomi releases their code for redmi note 3, and it wont be anytime soon.

Follow his guide. i was able to get volte with it. It is superb.
1. Flash miui 6.11.3 and wait till it boots. Use volte on both sims.
2. Backup efs.
3. Flash cm14 by abhishek
4. Flash cm14 firmware by abhishek.
5. Flash volte V2 files by sudeep
6. reboot and call someone using volte.
7. If it works then good, if not then restore efs and call again.
Note: There wont be any signs of volte. You will only confirm by calling someone.
After you get volte on abhisheks rom, reboot to twrp and flash your desired rom.
Then flash volt V2 zip
then flash other files you want to flash
Note: Do not flash any firmware after this.

Going to try installing AOSP Extended

Hello Everyone
Im going to install the AOSP Extended on my Redmi Note 4 Snapdragon (mido).
Question 1- I have a Reliance Jio Sim Card- would VOLTE work? i dont ever make use of Video Calling ever but only need the Sim card to work-
Question 2- Do i need to install LAZYFLASHER after the CM 14 firmware for Aosp Extended?

Yesterday I installed TWRP without the lazyflasher firmware- my Redmi note 4 stopped booting right after that. Someone named 'SEVENLIFE' helped me to get this fixed. As soon as I installed the LazyFlasher the phone started booting fine.
I just dont want to end up in a no boot or brick situation
lazyflasher is needed only if you use MIUI, no need in AOSP ROM's.

1) volte works with Jio

Thank you friends, I was able to install AOSP without any failure- everything works fine -
VOLTE works everything else does except for the ROOT PERMISSIONS.
Now im going to install MAGISK

Please note this ROM is only for the SPH-L520 (Sprint) only!!! Do not try flashing this on any other variant. Search XDA for your device, as there are loads of other ROMS for your INTL version
What works?

Great to see a new builder, good job!
Thanks
Many thanks for this ROM. It installed without the slightest hicckup and is working fine. Been looking and trying to replace the OEM software for quite some time now with no success. This was a breath of fresh air. Great coding. Keep up the fine work. Best Regards. Yachtsman
I got it working figured out there's a tool to do it, ty awesome work btw.
Heres's an updated version of Lineage 14.1 which includes November's Security Patch and an updated CDMA(I hope I spelled that correctly)
Updated by: @arco68 (thank him for keeping the s4 mini sprint variant alive)
ROM: http://www.mediafire.com/file/4pwp2...-20171121_233335-UNOFFICIAL-serranoltespr.zip
Thanks for posting! Got it working on my Sprint S4 mini.
Thanks for posting! Got it working on my Sprint S4 mini, too.
I use the S4 Mini's as media players. Lineage 14.1 has better media options than the original OS. Great player for $30 or even $50. My Rockboxed Sansa Clip is wearing out. Smart Audiobook Player is great for audio books. The really great part of using the S4 Mini is the ability to load new content from my personal cloud.
Thanks for the awesome work Michael! any idea which one of your nougat roms are funtioning the best; this one, aokp, or RR? thanks
Also any plans around here to experiment here with oreo or p? I know as it is, that getting nougat is great for such an old device, but its the last true mini sprint phone out there...
Awesome job Michael!!! I really like the size of this phone, and I am hoping that this ROM keeps my phone running for a while.
However, I found a problem when I flashed the phone: I cannot put an account to the phone. In other words, when I go to settings > accounts> + add account, my choices are Exchange, Personal (Imap) and Personal (Pop3). The choice for adding a google account for the phone to sybchronize itself with the google services: play store, App Data, Docs, Drive, etc is not there. Did I miss a step in the flashing?
I sideloaded google play, but it fails because there isn't an account on the phone. Again, Did I miss a step?
Thank you for your time and shared expertise.
R
I cycled thru the imaging, flashing, gapps thing, and now the phone has connectivity to the app store.
-- Ill create a new post about this, but when I tried to activate the phone, I needed to update the PRL (Sprint) does anyone know how to do this?
Thx
Flashed the original software into the phone, did all the updates and reflashed lineage, so far so good: Everything works as the OP promised. Great Work!!!
R
I installed the original sprint software, updated everything on the phone. Then rooted, flashed and installed Lineage. It has worked about 95%. The WI-FI connectivity has a problem.
- Sometimes it does not let go of the wifi connection when I leave my house & it drains the battery very fast, shut off WI-FI & the problem is fixed.
- Sometimes it does not connect to the wifi, and cannot find a signal (multiple & strong signals available), reboot device & it connects
Does any one have any idea how to solve the issues with WI-FI?
R
Halp?
Spamming this question here in case anyone else had a similar experience:
https://forum.xda-developers.com/galaxy-s4-mini/help/sph-l520-ting-4g-lte-t3817775
(TL;DR - can't get 4G/LTE on Ting even though everything else works perfectly?)
Curiously, I installed this rom on two sph-l520s successfully. After a month, I put back on one phone the Samsung 4.4.2 os. I did a twrp backup.
Several months later, I tried to restore the lineage backup. On reboot, this phone gets stuck with google framework stopped as well as other similar errors. I tried doing a new install after a wipe and it hangs at the lineage logo forever.
After many attempts and restores did not work, I installed the resurrection rom successfully.
Downloaded over and over and so on.
Now I have lineage 14.1 on one phone and resurrection on the other.
Anyone have a clue why this rom will not work on one sph-l520?
I made a TWRP build for the Sprint variant, and also builds of Lineage 15.1 and 16.0 if that's of interest.

absolutely fantastic, except i can't get any sprint service on the rom? any idea how to get it going/special zip to flash to trigger it? I already set up my service on stock rom, and On RR 14 I can get service perfectly fine, except that rom isnt stable and crashes on me. This one is great, just want to be able to enable my sprint talk text and data. THANKS!!!!

It's an issue with Sprint devices to get data working on Roms past Nougat.
Am itching myself to resurrect my S4Mini Sprint...

It should be working if you use the card in the first Sim slot
Hi,
I have flashed Pie Pixel Experience ROM in my note4 (Previously using Oreo Based Pixel Experience from more than last 6 Months), and VoLTE in first sim is not working (its JIO SIM in India).
There are following observations -
1. I am able to use Internet from same SIM from Both SIM Slots.
2. I was able to use VoLTE from Second SIM in Oreo Pixel Experience ROM.
3. Now it is not working in both the slots.
Any pointer for resolution is appreciated.
Regards,

Based on the latest omc from n950u. Clean rom flash is recommended but not required, and as always, MAKE SURE YOU BACKUP YOUR EFS AT LEAST! Can be flashed directly after the rom, no need to boot first. ENJOY!

It works for me
Added S9/S9+ and TEST version of N9. If you try the N9 please let me know if it works well. I don't have N9 to test...
I am using the TMO detonator on a Samsung S950FD and it works well (WIFI calling, VoLTE both working), including on a T-Mobile MVNO. I am wondering though if there could be a similar detonator prepared that would be for CSC XAA (which is the US market generic unlocked CSC). Using XAA would allow the same functions to work without having to reflash the phone each time the operator is changed. What do you think?

Is this as simple as restoring a rom backup and possibly also restoring EFS or is there something more to this that I should research?

Hi, since you know more about this phone I have a quick question
I got G955N and I'm running on this ROM
https://forum.xda-developers.com/ga...--s8-cross-device-development/thread-t3822134
which is pie based, and I'm going to switch with Verizon in future so I installed
https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-1-0-t3636739
last CSCSelection_SM-G95XF_V2.0.0_O_Final.zip which I believe is for Oreo base
it went fine, but after that my phone is mad laggy and I'm keep getting IMS service isn't working. is there any way I can add those CSC for USA base networks manually so it can work with Verizon and others USA base network?

ATT_pie_detonator_bigTINY_G95X_N950.zip for AT&T
TMB_pie_detonator_bigTINY_G95X_N950.zip for T Mobile
T-Mobile detonator works perfectly and I love that you kept it minimal to only get all the needed features working.
I'd appreciate a T-Mobile bootlogo removal though tbh
Sorry, I have done quite a few searches, but haven't found any clear instructions on how to install these files. I have a N950F, but use it on ATT, and would like to get wifi calling working. Any help would be appreciated.
I'm new to this. I also am unclear on how to install.
G950F, TWRP 3.4.0 and Magisk 20.4 running. Using Tmobile.
Is this something I have to flash via TWRP or via Odin? And how do I tell which Tmobile file to flash?
I went ahead and just tried to install it the best I knew how.
Phone: SM-G950F Firmware: G950FXXSBDTJ1 Security Patch: October 1, 2020
Carrier T-mobile USA.
I used TWRP 3.4.0 to flash “TMB_pie_detonator_bigTINY_G95X_N950.zip”.
In "Settings>Software Information>Service provider SW ver."
initial CSC was XEU/XEU/OPS.
post detonator it is TMB/TMB/OPS.
I note VoLTE and Wifi Calling options are now present in the drop down menu.
I note HD+ icon during calls now.
I note the 'signal strength' icon on the top now says 4G LTE instead of just 4G.
I'm experiencing poor signal strength and was hoping flashing detonator and getting CSC 'right' for TMO network would help. It has not. Still low download (~5Mbps) and very poor upload (~0.1-0.05Mbps).
My home/neighborhood has lackluster 4g coverage, one of few spots. The TMO-Sprint merger is partly to blame - they're transitioning sprint towers to TMO/making infrastructure changes due to merger. I'm informed things should improve in coming months.
I have yet to test whether everything works 'right'. So far it looks okay, but i'm setting up the G950F as opposed to using it, and instead to give up trying to make the G950F work as I need it to on Tmobile and go for a Pixel 4a 5G on Google Fi and hope that the difference in phone, and the 5g, and ability to switch between networks will meet my needs.
As another poster noted, the tmobile startup splash screen is annoying. I imagine one could hunt for which file to remove from the detonator and repackage it.
That said, thanks to the developers for this tool. It allowed me to answer whether or not optimizing the G950F for the Tmobile USA network would improve signal strength. As such I no longer have to wonder if there was a way to make the G950F work for me and perhaps in the future, when coverage improves, I might find the G950F works quite well and I can give it to a family member.
Does anyone happen to have the files and can reupload? This may be one of the last ways of obtaining t-mobile functionality for the international S8.
I am specifically looking for " TMB_pie_detonator_bigTINY_G95X_N950.zip "
The mega download link must have recently died... (or it just doesn't work for me?)
@LastQuestion any chance you still have it since you posted fairly recently and seemed to have success?
I need these files too
@Puremin0rez were you able to get them?
