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.
Hi
As youve found your way to the correct section (Xiaomi Mi5 Q&A), this thread is closed

Wait for other members to reply you in the Mi5 section
Thanks
I have a G8142 HK version (on Oreo). I am visiting mainland China and I found out there is a 'x' on WIFI signal (I guess it is because of blocking Google). The guy who sold me the phone flashed the oem_x.sin file of the Chinese ROM - in order for me to use VOLTE on China Unicom (I've activated the service with them).
And I fount out:
1. too many Chinese bloatwares e.g. baidu, weibo etc. - gone with flashing HK file, good!
2. the 'x' on the wifi signal is gone - and did not come back after I flashed the HK file (I want it to be there to show there is the Great Firewall, if I go somewhere which has free internet so I can see from the WIFI x)
3.there is still no VOLTE in settings-mobile network - as I go into testing mode (*#*#4636#*#*) the VOLTE provision option is still greyed out. I also found out in HK rom the video calling provisioned option is available but after flashing Chinese file it is greyed out(came back again after I flashed HK version of file).
So I'd like to ask:
1. is it possible to bring back the WIFI 'x' just like before? (Or return to stock)
2. anyone know why there is no VOLTE option?
3. Where do I get the official firmware? - I got the version G8142_HK_47.1.A.3.254 from the phone seller, but I'd like to know where to download them? Tried Xperifirm.exe many times it always stops downloading halfway, and also Xperia companion but the loading bar stucks at the beginning, maybe it has something to do with Chinese internet censorship?
4. while I am in China, before I flash a new firmware I'll have to delete my google account because when the setup menu comes it will ask me to put in my old google account to proceed, I heard it from somewhere, right? If yes I'll just wait for a week maybe flash it after I leave China...
Sorry to write so long. First time using a Sony phone...
1: use flashtool
2: yes through magisk module or use the rom turbo created. (module just adds the options if your phone has it on there, it does not engage volte, only the menu)
3: did you try flashtool?
4: flashed multiple roms on my xzp and not once has it asked me for the old account.
First of all a BIG thanks to ed-gonzo
He made this possible
This is the instruction to activate VoWiFi / WLAN Call on the Poco F1
Its tested and verfied to work with EU ROM (Oreo , Pie and Q based) and german provider o2 (Telefonica)
Before you read on i want to make clear that I am not responsible for bricked devices !
Basic requirements are root rights to do this mod
Maybe latest 2020 Qualcomm Diag QD-Loader Windows 10 Drivers signed are needed for this to work.
!!! Before doing this Mod you should backup EFS-partition !!!
- download QPST tool and install
- enable USB debugging in Developer settings
- now either go to terminal app and type:
Code:
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
or
adb from PC
Code:
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb
- connect Poco F1 with original USB cable to PC
- start PDC (from QPST tool) on PC
- Poco F1 should be recognized by PDC (if not install Qualcomm driver and check Device Manager)
- activate corresponding profile (in case of german o2 its DT_Greece)
- install VoLTE & VoWiFi Enabler Magisk module (optional) or activate setting with dialer code *#*#869434#*#*
- restart Poco F1
- Voila
FAQ:
Q: What are the requirements for VoWiFi
A: A provider resp. plan which includes VoWiFi
Q: How to know if VoWiFi is working ?
A: Put phone in airplane mode and reactivate WiFi only. If you are able to make a call then VoWiFi is working.
Q: Does this only work with MIUI ROM ?
A: No ... its reported to work also on Custom ROMs like LOS, crDroid ...
Thx for this guide! Have been waiting for this.
Does this work with custom ROM (LOS)?
in case of german o2 its DT_Greece? are you sure? german carrier and greece?

Ok thx will give it a shot as soon as I get access to a windoze PC :highfive:
Ok this definately didn't work on my Poco-f1 with latest LOS16 and 8.11.15 vendor/fw. Funny thing that VoLTE now seems to be gone (Device switches back to H+/E). Got it back by restoring efs. Has anyone else been successful with this running custom ROMs? Even without this "hack" I have been able to activate VoWIFI after 8.11.5 update but it didn't work so I guess this depends on FW version.
Two things - a little offtopic though: Any Idea if this can be tried on the MiA1? I suspect that xiaomi doesn't include support in it's firmware for this device at all and I 'm afraid to cripple both my devices (Poco and MiA1) at the end .
Has anyone had success getting HDVoice with BT headsets on the Poco-f1 with custom ROMs? Sorry for asking this here but in the LOS thread I seem to get ignored with this question / bug report.
@saski4711
to bad that its not working for you.
It defintively works with EU ROMs based on Oreo or Pie.

Yeah bummer. Will give it another shot the next days maybe I messed up somewhere. Isn't this device supposed to get VoWIFI by default with the Pie update anyway? Maybe this will work OOTB with final pie?
not works with EU pie rom to me too. from Sri Lanka we have VOWIFI network. tried switching many profiles but not works .

Dont know ... i'm on Stable EU ROM 10.0.6.0 (based on Oreo)
I know for sure it worked out of the box after pie update on stock beta with a service provider in Greece.
Can make settings appear with *#"#vowifi#*#* but being in India don't think providers support vowifi so doesn't work.

How can you be sure then?
Enabling the VoWiFi option doesnt mean its working !

2 diff statement.
Can enable with code but doesn't work in india.
It worked for a friend in Greece without doing anything immediately after pie update.
What I was suggesting that maybe and just maybe if provider supports it ,vowifi can be enabled simply by code.
It is working perfect. I did some test calls on wifi. Thumb up..... BTW I'm on German Telekom D1

could you please tell us which ROM you are using and which profile you activated within PDC ?
I'm using 8.11.27 global beta and I modified the DT_greece section. Set sub0 and sub1 to active.
Opened dialer and dialed *#*#vowifi#*#*
ok this works, just needed a bit more work for WoWiFi in my case
after a reboot it kept returning to my default carrier config (VoLTE working just fine anyway)
so what I did was to remove my carrier config from within PDC Tool, just that by doing that it defaulted to a non-VoLTE config
well, removed that also and this time it kept DT_Greece config on both subs
VoLTE works and VoWiFi also (carrier Orange Romania)
ps. don't restart phone if you want to test new configs
just click on activate and enter airplane mode then exit (keeps testing faster)
I've gotten as far as I can with my Mi Mix 2S, works on both AOSP and MIUI to allow the radios to be enabled, and the settings to appear in MIUI (AOSP usually shows them anyway).
With this said, I tried only enabling the WiFi option on the carrier that already had the sim activated...
I see many people here on different carriers in the EU who enabled the DT_Greece options and voila. Is this an accurate conclusion? I'm wondering if I just need an answer from a carrier other than my own to acknowledge the WiFi option exists to turn it on? Being in the US it seems as if the DT_Greece config could cause some problems, but it's not an option in my list. I don't know at this point.
Edit:
Tried all the US bands and even a few others, specifically ones that said WiFi. None worked so far, I'm going to cry! :crying::crying::crying:
I tried this on a Redmi Note 5 Pro but after selecting the device in PDC it throws an error message and doesn't show the list of carriers.
I've tried QPST 2.7.420 and 2.7.474 and a couple different pie roms, windows 7 and 10 but it always fails.
I can use EFS Explorer and dump the NV data just fine though...
Hi recently I have flashed to MIUI 12 EU ROM my Mi Note 10 & after that network signal does not work. It says RADIO OFF. Actually no issue with "Airplane Mode" This is I think some driver has missing.
I tried again flash original ROM with fastboot but didn't support. I brought to the service center & they said they can do the fixing due I bought through AliExpress & there is no this model officially launched in my Country.
I also noticed that my MEID is "00000000" is that a problem?
Great if anyone give me some feedbak on this bring my phone alive again.
Hi everyone!
I have a Note 20 Ultra (N985F) Exynos variant.
My mom bought it for me without knowing it is a live demo unit. When she bought the phone it was working (network and data) but it was on Android 10. I started getting suspicions when i tried to update and it said "failed to register". I wanted to check the imei codes on the back and there's when i found out it is a LDU. I flashed Dr.Ketan's Android 11 ROM and i lost all network functions and when i try to search for network it says "Error while searching for network" so i flashed a stock Android 11 firmware from SamMobile but the issue still persists. I think i f****d up the EFS, don't know yet. I didn't have the mobile data toggle in the quick settings panel but after deleting the files in the EFS folder it got back. I have a little clue of what's happening here but i don't know how to solve it. When dialing *#0011# the imei status is "NG". Don't know if Chimera tool or Z3X will solve it by payching imei certificate (i don't have a license for those programs so that's why i'm asking before buying one). Will flashing pit file solve my problem? Will flashing a combination rom fix the issue? If not, how can i solve it? (P.S: wifi calling works, but i don't have any other type of cellular network)
Mate, the Nore 20 ultra is model number SM-N986B. The fact yours is 965 is the reason you aren't getting updates...
Unfortunately, short of unlocking bootloader (and even that is not assured), you can't just flash to a normal stock rom.
Never mind, i got it fixed by @hainguyenthao. I was skeptical at first but he really helped me. Kudos to you mate!
I have a network issue G780F please @hainguyenthao
