Unlocking Basebands on MI4

I've done everything like this described by olokos, but something must be changed for our device. Do step 1 and 2 like in the link, download the attached modified diag drivers for Xiaomi from this post. Next you enable the diag port with *#*#717717#*#* and connect your phone to the computer.
Now go on with step 11, but find MI_00 instead of MI_04 and install the driver from this post.
Do everything including step 33, then you disable diag port by dialing *#*#717717#*#* again, reboot your phone and you're done.
Now the question - many people discussed about enabling LTE on MI3, but this wasn't possible due to the Snapdragon built in this device... But in our MI4, there's a Qualcomm Snapdragon 801 MSM8974AC, which supports LTE. So, how to enable it? I think some NVs must be changed using QXDM!? Anything else?

Will be awesome if we can enable the lte on mi4 device ??

I would love to see a working LTE on this device soon.

Would be totaly awesome. Watching this.

If I am not mistaken it uses the MSM8274AC instaid of the MSM8974AC wich is the same chip except it does not support 4G, if LTE could be enabled I will buy the device right away!

So you tried it but it hasn't worked? I'd like to get this phone but the LTE was holding me back. I came here to see if there was any success in unlocking bands but you seem to be the only one questioning it.

Would like to know as well. Lack of LTE in the current variant is what also held me back from purchasing.

With LTE it didn't work until now, in the post from my link there is only described unlocking GSM/WCDMA bands until now, not LTE. But it is a MSM8974, only the MI3 had an older version. This is a screenshot from QPST with connected Mi4...

hi donpinsen does WCDMA actually work after you unlock the basebands? I've followed every step in your guide, but still I could not get the 3G WCDMA work on my MI4, even though QPST shows that all WCDMA bands are unlocked. My phone is the TD-LTE version, and I am sure that my location is covered by 3G WCDMA. I think the hardware of my TD-LTE MI4 does not support WCDMA signals. any ideas?

Try clearing app cache. Go to the installed apps setting >>> Play Store and Clear Cache and run it again.
I do not own a mi4 but this method usually works with other apps that have crashed for me on other devices.
If that doesn't work, I read one solution that insist you install the GMail app, sign in. Reinstall Google play services again and then reboot the device.

I wonder if this works on the Mi4, mine is coming tomorrow...

Any Updates?

Going to try some of the NV edits on my extra 16GB Mi 4 when I get to my desktop, will report back if I can get AT&T 4G LTE bands going.

i've managed to edit nv value as described but if I search network no lte is dispayed. maybe modem is not compatible?

Try going into settings, about phone, internal memory tap five times, set preferred network to GSM/LTE. Let me know what happens.

in that menu if i try to select lte only option the phone select wcdma preferred instead while if I set LTE, gsm/wcdma option no lte are visible in network search.
update
someone knows if exists an app or anything else to check which frequencies are enabled from phone itself?

[Q] SIM2 data speed

Huawei reports SIM1 to support 2G/3G/4G and SIM2 2G only.
I wonder if SIM2 may work in 3G/4G at least when SIM1 is deactivated?

yes. some Chinese managed to hack 3/4G for sim2.

More info.
The method involves flashing a custom cust.img. Or replace codes in local.prop.
Then sim1 and sim2 can be switched on an interface that any 1 use 4/3/2G the other stay with 2G.
Does not release more frequencies to any sim.
Does not support both sims on 3/4G. 1 must at 2G.
Update: did NOT work for me. I am on 2.3. Maybe need 3.0 to make it work.

yeah,it works,nice feature.

Can you make a guide so we can try it also?

power off the phone, enter fastboot mode (while holding volume down insert usb cable and wait till fastboot screen appears), flash cust.img from link provided hereinafter using fastboot.exe and restart the phone.
all flashing at your own risk. original thread states it is for b310 and factory resets should be done before and after flashing. I did not do any resets, also I am not on b310 and it works w/o problem

Hi nrpetons,
What ROM are you using? I have the L12 and I want to kick out the original huawei rom and your ROM it what I was looking for

It worked for me also
ROM 5.1.16 dev

I am on some custom chinese based on 5.2.1 for l02.
I believe it will work for l12 with any version of emui 3 roms.

Activate 4G on second sim without flashing cust.img
Important update on this hack !!!
I don`t know much about programming, but this is what I did to activate this option WITHOUT flashing the cust.img provided.
I edited local.prop and added the following lines at the end:
Code:
ro.config.dsda_single_rild=false
ro.hw_sglte_shareantenna=true
ro.lte_gsm_shareantenna=true
persist.radio.svlte_psshock=600,4,1200
persist.sys.dualcards=true
ro.config.hw_dts=true
ro.config.hw_nxp_eeapi=true
hw.npm.asyncntp=true
ro.config.distinguish_hspa=false
ro.config.hw_mirror_chip_v9r1=6
As I said, I don`t know much about hacking, maybe I added some extra lines, but those lines seemed related.
I also copied the file SUPLConfigParams.xml from the above cust.img because it had some LTE, GSM parameters modified. I have added this file to the post.
I confirm that the dual-active function is working.
So , for those with more experience about this, please update the above experience and tell us if there is something we should leave out.

maybe 2 line of codes are resposible
In a post many peaple experimented to change 2 line of codes to activate 4G on sim2. They succeeded.
http://bbs.anzhi.com/forum.php?mod=viewthread&tid=9563906&fromuid=25626505
in cust\unicomelectric\cn\prop\local.prop
Code:
ro.modem.type=6260
persist.sys.dualcards=true
It did not work for me because I am on 2.3. Has to be EMUI3.0.
@mihaipi one code in your lines. Are you on 2.3 or 3.0?
@Zentachi you can try.
.

@soma, I read that chinese thread. do u understand it that both card should be able to have 3g/4g in same time or one will always be 2g? than it would be just easier way of switching 3g/4g from sim1 to sim2 and vice versa compared to flashing cust.img...
btw, I am on emui 3 and have both lines

@soma900
I tried that method with the two lines and it worked
@nrpetonr
I believe it is only to switch with sim card you want to operate on 4G
Maybe later someone will unlock 4G on both sim cards at the same time

Thanks guys, this is indeed very interesting for many users, ie. those travelling often and needing to swap the cards physically often for having 3G connectivity. I can't see why on earth the option isn't built-in in the settings, if it's possible to swap hardware-wise..
I assume root is required for editing those lines. And then simply search that file and edit those lines. Is that it?

Does it works for Honor 6 Plus LTE version too?
I need to be sure before buying the device.
This is a very essential option for people travelling abroad or people who needs to switch off one sim at times (typicallly people who use one sim for work).
I really don't understand why it's not built-in, I am let down by Huawei.

same effect. Only one sim can use 4/3G, another keep 2G. Advantage is that you can switch 2 sims via the interface. Otherwise one need to switch phone off, switch sim cards in 2 slots, turn phone on. kind of burden.

Flight mode and then switch the card then flight mode off, so no need of switching phone off completely. But still it's something you'd rather avoid, especially when the hardware is made for it and Huawei left the option out.. Cause that Sim slot cover looks like going to tear apart..

What's the point in having 2 sim working in 4G at the same time if you can only use data from one sim at time?!?

Question How to get Wifi Calling on Freedom Mobile

Hi,
I am using Freedom Mobile in Canada and bought the Sony XPERIA 5 III 5G XQ-BQ72. This is a taiwanese dual sim.
The basic services work but the enhanced services don't. I checked before hand and knew that to be the case but having read forums I thought I might be able to get it working.
First I tried @Gigio755 advice here https://forum.xda-developers.com/t/xq-at52-volte-or-wifi-calling-in-canada.4128611/
Where you dial dial *#*#4636#*#* and switch Vowifi on. But the thing is greyed out
Next I tried was @BSPI advice here
https://www.reddit.com/r/freedommobile/comments/bg5x3c
That's where you text *#243203855# then choose GLW, but I get MMI error.
I've also tried @f1v12 advice here
https://www.reddit.com/r/galaxys10/comments/dbf1lj
Where you text #272<your phone's imei number># but also get MMI error
To fix the MMI error I tried following https://www.technobezz.com/fix-connection-problem-invalid-mmi-code/
These didn't work, but specifically I couldn't try method 3, Turn on IMS over SMS because my IMS is not registered
Following @sooki99 here
https://www.reddit.com/r/freedommobile/comments/c331l5
I tried to register an apn type ims, but got an error saying Freedom does not allow adding apn type IMS.
I've contacted tech support with Freedom, they said they registered my IMEI. They also said they don't need to provision my IMEI so I'm not sure what registering they did.
So, I'm wondering what the next thing to try is. Is there a way to fix the MMI error so I can at least send dial codes?
I was thinking of flashing the US firmware next, does anyone know if that works? I know I'd loose the dual sim support (on a side note, why is that?), but does anyone know if that would help?

I have also the problem with wifi calling feature with Israeli operator. The feature on the network side activated, and they checked it with the phone number. They told me they don't need IMEI for wifi calling, and if the phone supports it, the option should appear on the phone''s menu, but it doesn't appear.
I got the phone from UK, it's dual sim model XQ-BQ52
Any ideas?

Hi @dima_vy
First thing to try would be the firmware flashing. You can do this without rooting or boot unlocking.
Get xperifirm and newflasher. There's a few customizations for XQ-BQ52 you can try without messing up your phone. I have the XQ-BQ72, and when I tried the 52 firmwares, the phone works but the modem connects and disconnects continuously so I doubt you'll find a working solution from the 72's.
But...
From a comment by @noldoli on:
Thank you ASUS for implementing VoLTE & VoWiFi for Telstra, Australia in Nov 2021 Firmware Update
Please tell us some basic information before asking for help: Model Name: Rog 5 Firmware Version: WW_18.0840.2109.188 Rooted or not: Not Frequency of Occurrence: Happily always! APP Name & APP Version (If your issue relates to the app): Phone calls In addition to information above, please also...
zentalk.asus.com
it really looks like you need:
The phone having the necessary MBN files for the mobile carrier in question
The SIM having VoLTE provisioned by the carrier in question
It really seems you need Sony to include these files on their updates, which they are unlikely to do in countries they did not release the phone. BTW, if you ask Sony they will blame the carrier.
So, I think the next thing to try is with a root, following @astracd guide for the onplus 5: https://forums.oneplus.com/threads/oneplus-5-5t-freedom-mobile-wind-wifi-calling-and-volte.880807/
You need to root, and try replacing the mbn files from the pixel 4 (assuming they have the israili customizatins). It's an older modem. but that doesn't seem to be a problem.

Here was a Guide. Someone said people don't care about Me or My Work so...

I couldn't get my superuser to work (so must not have been rooted properly), so I couldn't continue testing other mbn files. I'd love to hear if someone has success with this method though.

mbn file must be for the phone with same chipset.
Pixel 4 uses Qualcomm SM8150 Snapdragon 855 and Sony Xperia 5 III SM8350 Snapdragon 888. So pixel mbn file will not work with this phone.

OK, I see guys, thank you for advises. I don't see any Israeli versions on any other models... I will try to do more research.

PHHs AOSP GSI based ROMs will have a way to force VoLTE and WiFi Calls on any way. If You can live with AOSP, that will BE the easy way (possibly)

I read today about android 12 coming to Xperia 5 iii, may be it will fix the issue

I just checked again, and there is a global version for XQ-BQ52 with CID 23365115. Is there a way to check what firmware i have exactly installed?

Android 12 didn't fix VoWifi issue

Hi,
I've seen there's now a USA customization out. Does anyone know if that will work on Freedom in Canada?

Unlikely. Sony does not have Wi-Fi Calling on AT&T, T-Mobile, or Verizon.
They only had Wi-Fi Calling on the XZ1 Compact on T-Mobile. Literally just one phone on one network in all their history.

There is a version for global market for XQ-BQ52. May be this one will work?

That's exactly the issue we face. I have the Xperia 1 II and flashed SEA firmware to get volte working but I don't think I will have the same success with Xperia 1 IV.
I would definitely buy the Xperia 1 IV if I know volte will work. It's an expensive phone and having no volte will make the phone useless once 3G network is shut which is imminent now

I have now Xperia 5 iii, and I'm not sure that there is any firmware that will allow me to use volte and vowifi in Israel. According to Sony, as they don't sell phones here, they won't provide firmware which will support these functions in Israel... Israeli ministry of communications allows operators to shut down 3g networks in 2025 I think. I expect this phone to work more. My previous Xperia x worked 4.5 years.
So I just hope that there will be a way to use Sony phones in the future

If the Xperia 1 IV doesn't have success I will get the Pixel 7 Pro as that is locally available which volte/ WiFi calling will work out of the box. However I prefer Xperia 1 IV but not going to pay for a phone with limited features. 3G network will start to shutdown this year for Australian network operators

Question [China ROM] Banking apps can't detect my sim cards properly

Hello everyone!
I purchased Xiaomi 12S ultra 12GB 512GB variant from Giztop and it came with google apps preinstalled and with english language. All the other apps from my google play store library work fine except all banking apps. They can't seem to properly detect my sim card somehow.
Sim card detection works fine on apps like whatsapp or other apps that read verification code automatically.
In attached screenshot above, I have tried to verify my sim 1 number in one of the app but it has always failed. I can't figure out why this is happening.
Another issue I am facing is my Whatsapp contacts revert to unsaved phone numbers automatically and I have to manually refresh my contacts to restore them.
Could this be due to some configuration I haven't done in phone's setting? Will flashing with EU ROM fix this issue for certain?
Please suggest me anything you can think of regarding this issue.

You may need to change permission settings in app info, because MIUI doesn't allow 3rd party app to read phone number written in SIM card in default.
Settings->Apps->Manage apps->Your banking app->Permissions->Get device info->Always allow

It seems in addition to this, my phone was sending messages from sim #2 for verifying sim #1 for unknown reason. I didn't see any option to set default sim to send message (default sim for call and data is set in settings but no default for messaging) and that was the reason for my 6-8 hours of pulling my hairs out..
I had to take out sim #2 from phone, then the outgoing message number matched with number on sim.. and I got it to work. This seemed like one of the silliest mistakes after I noticed all the outgoing messages were from sim #2. I noticed when I tried sending myself message to see if I have balance to send messages.
What I tried:
1) giving the app permissions for read and send message, read service message, get device info
2) withdrawing the consent for MIUI Security app, clearing data / force stopping
3) reset mobile data, bluetooth and wifi network in settings for each sim card
4) factory reset my phone
What worked:
take out the other sim, and try with only single sim in the phone.. worked for me.

Did it work with Indian sim cards? Any issue so far and did you flash custom rom like Indian version or it still have CN version? Camera better than 11 ultra or not?

Camera is truly impressive (see detailed reviews and comparisons on youtube). It works fine with Airtel/JIO after above mentioned changes. I would suggest wait for 13 Ultra to launch globally. They have made minor upgrades that may interest you.

Question Cracking/squealing between phone call

Hi.
Today I ported all my things from P5 to P7Pro and I noticed a very annoying thing.
In every call, after a minute or two there beggins cracking/squealing, like it's a bad connection.
I updated the phone to the latest Android version (screen in att). I tried restarting, with another SIM but the same ...
No problem at all on my P5.
Anyone else facing that?
I'm really disappointed that this disables the basic use of the phone and I don't even know how to start reporting a bug considering I'm using the phone in an unsupported country. :/

Strange one, not something I have nor read anyone else having. I'd suggest you have a faulty handset if you have tried another sim from another sim in it (presumably from another provider).

Do you have clear calling enabled? Not sure if it would make a difference, but I did see one or two people report that their connection was worse with it, although for most I think it's better. Not sure they reported crackling/squealing though.

I read about CC, but in my version there is no such option for now. Waiting for upgrade ...

Hello I have the same issue with Italian PosteMobile.
Where are you from?
It starts after 5 or 6 minutes in call.
Same phone but with other operator I have no problems.
Is your operator a virtual one? Full MNVO?

Hi!
Not so great for you and me, but great that I'm not the only one.
I'm from Slovenia.
Hm, strange, so something with operators u think? I'm on Telekom Slovenia, so biggest national operator ...

Idk but I know someone that works for my operator and they will try to understand what's the problem, in theory...
I'm also thinking opting in Beta Android to check if a newer rom fixes the issue.
If I have news I'll post here!

Hm, today I had zero issues up to now.
Yesterday in the evening I took out my primary SIM card, cleaned SIM slot with air pressure ...
I keep fingers crossed!

Same issue here but I only get it after exactly 20 minutes of calling. I'm using kpn Netherlands with a esim . I migrated from pixel 5 also with esim on same provider. I must note that after I disabled 2g calling from the settings that not all calls have the issue anymore.

Same problem here in Portugal after 15m in a call.

I must say that now after testing a couple of days with the 2g slider turned off, 90+% of the calls go without big audio issues. Only sometimes 1-5 seconds long distortion of some kind is left

Hello, problem still present after many updates and now on last beta.
Probably most of you solved it by switching to another operator, but I can't.
I opened an issue in Android Bug Report and discovered through logcat that there are some duplicate received frames.
If you suffer from the same issue I kindly ask you to post in this official issue link to let Android developers know that I'm not the only one with this problem!

Take a look to my answer number 6 to see the logcat :
On a Windows PowerShell:
adb logcat | find "F1:ERR"

If the problem remains unsolved I will sell my Pixel 7Pro, I can't work with this issue (and cannot change operator as it is the professional on that gave me my employer).
Thank you!

Same problem here

Hello, as of today nothing changed, just updated on beta 13 (T2B2.221216.008)
Annoying...

Same problem here!
After about 8 minutes of calling with Postemobile operator (Italy), the call starts croaking! More and more often I receive text messages from people who have looked for me, despite the fact that the phone was always under excellent signal. Postemobile still has VoLTE not enabled on Pixel7.
