Solution for Redmi Note 3 Volte issue

http://en.miui.com/forum.php?mod=viewthread&tid=402767&mobile=2
A little backgroud:Like most of the users of Redmi Note 3,I have been at wits end to get volte working on the recent versions of global developer rom.Post 6.9.22 I wasn't able to use volte and since the feature was essential to me,I would revert back to 6.9.22 global developer rom.
Soultion:Here is an easy way that would help you guys to get volte up and running on the recent versions of MIUI.I backed up my 6.9.22 rom using TWRP ZCX,since I had volte working on it.I installed the version 6.10.27(since it was on my laptop,tested on 6.11.3 as well..screenshot enclosed)using TWRP ZCX,then restored the modem and efs from 6.9.22 that I had backed up.Volte is up and running.No issues so far.Will update this if I face any issues.
Result so far:Volte is working flawlessly on 6.11.3.In fact it is better than in 6.9.22,where you had to delete the APN to get volte.Also no issue of data being on at the time of volte,like it was in some earlier builds.Posting a screenshot as well.

Anyway to install 6.11.3 using twrp ??

i havnt faced any volte issue, m always on latest beta.

I will recommend TWRP ZCX as I have tried it multiple times.Most recently I flashed 6.11.3 yesterday.On TWRP alka I got a soft brick.So I can't say if TWRP will work properly.

either you flash boot image patcher or use modified recovery.

There is a minority of people on MIUI forums also who say what you are saying.I have even tried clean flashing on my device,but it doesn't work.As I said you are the lucky few.For the rest of us it has been 6.9.22 all the way.At least till yesterday.Hopefully the developers will find a permanent fix.I am not complaining as the fix I posted yesterday is working flawlessly.

anyways i barely use miui forum so no idea about it, and builds are perfectly fine because we all downlods frm same servers, issue may be device specific or may b large batch of devices are affected frm it, btw global beta releases for RN3 qualcom were suspended after 6.10.13 bcoz few major bugs have been reported on few of the devices, may be you r one of them.

I myself suspect the same.Maybe some differences in device hardware.Global dev 6.11.3 has been released yesterday for Redmi Note 3 after being suspended for a few weeks.I was on 6.9.22 and initially downloaded the ota zip and dirty flashed it.Lost volte.Then reverted to 6.9.22 and decided to do something.lol.Can you tell me which version you last used fast boot ROM of?Just curious.I just yesterday saw a mod telling a poster that volte is working fine on beta 6.9.22 and global stable 8.0.6(haven't tried that..tried 8.0.5 but volte wasn't working).They are well aware of the issue.That confirms that there is one.
PS:Also if you dirty flash to 6.11.3,please do post your experience here.Whether volte works normally.

as i can see in screenshot above, you are using 2 gb variant, and i use 3gb variant, we are on different soc so it quite obivous that we will have different experiences. i still wonder wat kind of problem you are talking about because i never suspected anything like that.. i flashed 6.8.x as a last fastboot rom, afterwards i do dirty flashes, i used boot image patcher previously but nw i do it with zcx twrp. and 6.9.22 was quite stable build for me.. i didnt noticed any bug in anything. i hv jst flashed 6.11.3, its booted up, and seems fine to me as well.
Edit: Everytime i flash beta builds, i need to flash super su, xposed, few mod zips as well... and i have toremove bloatwares and few xiaomi core apps too everytime.. after all these efforts the rom becomes so smooth and fast to play with.

I didn't know you have a 3Gb variant.One thing is clear to me now that there is a definite issue with certain devices and I own one of them.As is evident we have a slightly different hardware configuration.But thankfully not a big deal now as I have it working flawlessly and xiaomi can take its own sweet time.Enjoy the new update.

Nova Plus MLA.....

Is it possible, to open a thread for the Nova Plus MLA-LXX only?
Root, firmwareupdates , etc.

i think its a good idea...im in canada /rogers with mla-l03...and not much here for our version

Not rooted ( yet ) but got the unlock code, me too
have the code, yet not used, all my other mobiles ihave rooted

Like i said...our device is a one pretty young...birth in september so...theres no rush to "enter the dragon" :angel:
But very anxious to try nouEmui

i have tried the unlock code, and it works, but i have relocked it.....

I've the MLA-L11 too. would be awsome to have a working TWRP , no use in getting bt unlocked
unless there is a custom recovery. I'd say we find a dev and donate enough to persuade him to work
on a twrp !

Hi, where is the android 7.0 for us, I hate Huawei when they are late on softwares....! I'm having a problem to use youtube over the phone network with my Nova Plus.
Thanks

guys the MLA varients work with xelfmade's TWRP recovery and roms can be unified to work on all varients

Ota upgrade made with my MLA-L03 to Nougat yesterday and all working great! Used FF to push the update via proxy and changed from C654B140 to C578B302 with stock updated app. Best I've like the phone yet!! Big improvement in every aspect so far.

Buddy,
for us using the MLA-L03 can you explain in details how you did that ? Been waiting for ages to get that OTA update that never comes lol
Thanks in advance

Hallo,
are there any News about my MLA-11 C432? I can´t find any actual Nougat firmware, is there anyone who has the same Model and try it out?

You can try this to update to Nougat: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G79/g0/v73849/f1/full/update.zip Extract all the files and place them in a dload folder then place that on the root of your SD Card and install it using the three button method. If your Build Number is not showing up correctly after installing that install this: http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_MLA-L11_hw_eu.zip using the same method as before. If it does not work the first time you may need to flash the stock EMUI 5 Nougat recovery which will let you install Nougat updates, I had to do this for the CAN-L01C432 variant as the update kept stopping at around 40%. EMUI 5 Nougat Recovery: https://drive.google.com/open?id=0B4T1GJ6EZ3LvTWNpZ0p5YXVINGs It is up to you to try it and I am not trying to make you as I do not have a MLA variant so I do not know if it will work or not. I hope this this helps.

Like I said you may need to flash the stock EMUI 5 Nougat recovery first before any of the Nougat updates work, the big update is the Nougat update and the smaller one is functionality. Let me know how it goes if you try it.

Yes, understand, which build is it and is there no problem to get the official one when i had install it?
If it doesn`t work how to get back to notmal firmware?
I have all my devices rooted , but this one not, there are to less informations about my build, therefore i have no twrp installed.
Im careful, my last device was honor 7, and i have no problem with twrp and root, but more informations.
Download is very slow.
Do you have made the update to nougat, and does it run without bugs?

CN 28S might be the best modem firmware

Heyyo,
UPDATE: I now recommend FULL firmware and not modem only firmware. I have links to then on my LineageOS 15.1 for X2 thread here:
https://forum.xda-developers.com/le...geos-15-1-oreo-leeco-le-max-2-t3771577/page24
Use whichever feels best. Some say Chinese 28s, some say developer 466D so it's up to you to decide for your device.
Original post:
So after some testing? I think that Chinese 28s modem firmware might just be the best one of the bunch.
I get the best signal strength I've seen yet plus the fingerprint reader speed when the device is asleep is still darn good!
Usually, at my kitchen table I get two signal bars but meow I'm getting this just like the attached picture
Otherwise? Developer 466D is also really good some have reported. I'd recommend people test this if they find Chinese 28s not to their liking

Which ROM were you using when you flashed this? I just tried on RR and the phone enters a bootloop. It passes the LeEco logo and the screen goes black. Then, a minute or so later, the phone reboots by itself and the whole process repeats over and over

works for me. can not tell if there is any difference.

---------- Post added at 04:16 PM ---------- Previous post was at 03:52 PM ----------
Ok. I clean flashed the ROM again (RR) and it worked this time, but I don't see any difference, either

i used rr long time but switched to eui short time ago.

@ThE_MarD
Thanks a lot! I was a little bit skeptical that it can make a difference, but somehow I decided to give it a try. So I've installed the 26s modem and I have to say that the fingerprint sensor feels much more snappier than before. Still it's not at the level of Letv 1s that I've owned previously, but it's fast enough. About the connection to the network, I cannot confirm anything, but the FP sensor is faster for sure. At least I don't have to stick all the finger to it to get detected. EXCELLENT!!

Thanks very much
the fingerprint is really better and faster on 26s
i was on the 23s modem firmware and some times the FP is not responsive and slow
but now it's really good .

Heyyo, I've tested it with (in no particular order) OmniROM, LineageOS 14.1, BlackX, Slim Roms, Paranoid Android, AEX, Pure Nexus Project and Dirty Unicorns. Modem firmware flashing works with any ROM.
With WiFi dropping? Hmm sorry but I haven't faced it yet... For your router does it have the latest firmware updates?
For mine I've also forced it to only use WPA2 with AES encryption. Works good as before it was set to auto mix of WPA 1 and 2 with both TKIP and AES encryption which is only good if you're connecting old devices like the original Wii or an original Nintendo DS which doesn't support AES and WPA2... So that could be something else to try

Yes, it has to be installed within TWRP. Just flash the zip and reboot, no need to wipe data, cache or dalvik.

Hhmm well every wifi device can act differently eh? Just my recommendation for your router anyways since WPA1 with TKIP encryption is nowhere near as safe as WPA2 AES which has less security weakness potentials (minus the recent one that is heh).
Otherwise? I'm not sure what to say amigo. Have you tried OmniROM last build? It is really darn solid.

Lineage OS H815

Hello,
I recently noticed that the LG H815 build has been removed as a download because of an encryption issue, and I was wondering if, other than this, there were any other issues causing it to be taken down (I'm thinking of building it unofficially)
Thanks

There is an unofficial LOS build already. That's what I meant to say.
Yes encryption is the issue why we do not have official ones but encryption is fixed on aoscp by our genius kessaras. Ask in kobtuls LOS thread what the state in LOS is.

You just need a V29a modem and bootloader package if you have a H815 handset, and you can actually flash that in TWRP as there is a flashable ZIP for that. I went straight from OEM Lollipop to AOSCP Oreo without issues.

as far as i know if you have h815 that unlocks with .bin key from LG its bootloader its unlockable and it has antirollback 0 unless you have h815t or h815p thats locked bootloader and cant rollback i think
ask in thread and tell them if you have official unlocked boorloadre from LG. if you can roll back if you flash v29.

You CAN use an outdated modem partition. But you may encounter issues like camera crash, bad or no sound on voice calls, gps probs and / or sensor issues.
And depending on several things it's possible that it JUST WORKS FINE. I have tested even a LP modem partition with oreo (just a short test a while ago) and all was working here but issues can happen rarely.
A brick is possible but it will be a soft brick only which means the download mode is still there and you can flash a kdz to recover if needed. It either bootloops or a demigod bluescreen will happen on boot.

And depending on several things it's possible that it JUST WORKS FINE. I have tested even a LP modem partition with oreo (just a short test a while ago) and all was working here but issues can happen rarely.
A brick is possible but it will be a soft brick only which means the download mode is still there and you can flash a kdz to recover if needed. It either bootloops or a demigod bluescreen will happen on boot.

Thanks for confirming this. I want to keep as much of my phone stock as possible so it is easy to revert back to full stock if anything happens (this is my first proper venture into custom ROMs).
Also, is there any way to tell which version the rom requires by looking at the install files

IN2025 - Open Beta 3 to Stable Branch

Hello!
I've got the IN2025 (global/NA) version of the OP8Pro and have been running Open Beta since it released. I want to downstep to the Stable branch of releases as I plan on selling the phone soon, so don't want it on a beta build when I do so. However I've not been able to figure out how. I attempted downloading and attempting a forced update and it didn't work, and have not been able to figure out how to get it working.
Anyone able to help?

There's a few guides for this already but generally speaking going from ob3 to stable you'll need to wipe.
1. Back up
2. Disable magisk modules
3. Download oxygen updater.
4. Take the install
5-A) I didn't use the ob3 release but at this point if you were going from 10 stable or 11 stable to 11 stable then you would click install on the update and then before rebooting you would install magisk to the slot after OTA, you can try this but may not work and shouldn't make any difference.
Or
5-B) take the update, let it wipe, set up phone, install magisk manager then flash a patched boot.img
You didn't state of you're rooted or not, If you're not rooted then follow 5-B but obviously don't bother rooting.
If you are then it's your choice.
5-A would be considered a dirty flash, I'm not sure if it will allow it coming from OB to stable, it should seem obvious when you're going through it.

I just downloaded an unofficial rom that allowed a downgrade and straight from than just to be on the safe side installed the official current firmware

I just done a Google search

EDIT: Seems the links on this site are official downgrade links anyway

Yeah i know this post. But i thought you have found an unofficial version which allows a downgrade without wipe.
Because i read something about that. Not sure if thats fake info.

I don't think you can actually do that.
From my experiences. Especially between bases ie: 11 to 10

You've got a newer version of the Firmware installed now so why would you want to even try downgrading without wiping, talk about compatibility problems

Dude what you are talking about? I don't want to try anything. I have just misread his post and thought he was able to downgrade from open beta to stable without wipe. He said "unofficial rom" and i read somewhere there were some guys able to do that with a modified rom. That's all.
