Enable LTE bands

Hi. I want to share my experience with you. See, I live in Mexico and here the only available bands for LTE are B4 and B2, and it was nice to see this phone being compatible with B4, so I ordered mine as soon as it was available in black color. It arrived last wednsday, and what I found? That it was not able to connect to LTE, I though it was a configuration problem, but then I revised the manual included in the box and it clearly says it's only compatible with B1/B3/B7/B8/B20/B38/B40. Damn, I felt so bad, I made a little research googling and realized that there are going to be several versions of this phone and the LTE support is going to depend of the selling area. This was hard to accept, but also the key of a posible solution. This is supoused to be a phone sold worldwide, and if there are several versions depending of the selling area I guess is easier and cheaper for production to make exactly the same hardware rather than one for each selling area, so maybe the only constraint for LTE support could posibly be something related to software. And so it was. I wanted to try to modify the NVRAM values to force the SoC to accept B4. For this as you might know you need an unlocked bootloader (for root) and a rooted phone. So, first I unlocked the bootloader, something really easy to do by the way, and then looked for a CF-auto-root zip (it is officially supported by Chainfire), then flashed the boot.img aaaaand, when my phone turned on, IT WAS CONNECTED TO LTE SIGNAL, no NV values were changed, anything else but this was done to make Mi A1 to support LTE B4. I can't see which other bands were enabled, I don't know how to see this since signal guru is not free for this feature anymore, but I assume that also other official supported bands were enabled.
Hope this can help someone else in a similar situation than me. I don't know if flashing a boot partition is enough to change LTE support, if so, its probably that the phone locks again with an update, but I guess that reflashing the boot.img or even a full ROM can make it support LTE bands again, and the worse scenario would be to change NVRAM values cause I alredy confirm that its able to support more bands than stock, I mean, the hardware is there so you just have to enable it. And yes, LTE is working fine with no issues.

Man...I just ordered on and I'm in the United States. It says "4G: FDD LTE B3/ B1/ B4/ B7/ B5/ B8/ B20; TD LTE B38:2600/ B39:1900/ B40:2300 MHz" under Network. I'm with Walmart's Family Mobile (they use T-Mobile's network). They say that you need a GSM phone with either 850 or 1900MHz band.
I hope this works...or else I have to return it...to China.

Can someone else confirm this?

When I bought mine the seller also said in description that it was B4 compatible, but when it arrived and saw the manual page with the phone specs, it clearly said that only supports B 1/3/7/8/20/38/40 (I'll attach a photo), and also the problem that it wasn't able to connect to my local LTE network.
As I said, I can't show you which bands are now enabled, I don't know how, if someone knows a way (different from Signal Guru) just tell me and I'll gladly do it
Edit: Forget about it, finally found how to show LTE bands with signal Guru without buying it. Screenshot attached showhing B 1/3/4/5/7/8/20/38/40 enabled! :silly:

I ordered my phone through Aliexpress...so whenever I recieve it...I'll pop in my sim and see. I'm pretty sure you're right...but I can still hope. China is on Holiday at the moment...apparently the entire country is shut down.
I know nothing about rooting a device. I've used my phones as is. I'm using a Nextbit Robin right now. Overall I'm pretty happy with the phone...but I want something with a better camera.

Oh true, I guess the whole country stops like for 2 weeks, you'll have to wait a little longer. And I hope your version gets B4 stock enabled, but if it isn't, is not a hard process, practically all you'll have to do is copy paste some command lines to your terminal/cmd window. Is a really developer friendly phone, is really easy to unlock the bootloader, and really easy to flash the CF-auto-root image for root, I guess it's been the easiest one I've ever had

Hola, también soy de México y la verdad es que me a pasado exactamente lo mismo que dices que te paso a ti, me enamore del teléfono y lo compre en cuanto vi que un vendedor lo ofrecía diciendo que funcionaba en B4 y de igual manera cuando me llego al ver el manual y probarlo me decepcione. Porfavor te pido amablemente que si lograste hacer que funcionara la banda B4 me ayudes a hacerlo funcionar en el mio, ayúdame explicándome bien cual fue tu proceso y los pasos que hiciste.
Gracias amigo ojala y me puedas ayudar de verdad te lo agradecería.
Hello, I'm from Mexico too and the truth is that it happened to me exactly the same as you say that happened to you, I fell in love with the phone and bought it as soon as I saw a seller offering it saying that it worked in B4 and in the same way when I came to see the manual and try it disappoint me. Please kindly ask me if you managed to make it work B4 band help me to make it work in mine, help me explaining well what was your process and the steps you did.
Thank you, my friend, and if you can help me, I really appreciate it.

Mi solución
Igualmente compre un mi a1 en AliExpress y en el folleto no menciona la B4 y al probar con varios chips telcel no daba 4g. Como ultimo recurso reinicie el equipo a fabrica y al empezar las configuraciones iniciales en donde pide escojer el idioma puse español (mexico) y al continuar con las configuraciones se conecto a 4g de telcel. Anteriormente escoji español (españa) y fue cuando no conectaba a 4g

I have ordered this phone from aliexpress as well, I was wondering if it's possible to activate the B28 LTE frequency... Unfortunately is not listed anywhere, I am not sure about it (but could be extremely good here in Australia).
Thank you

Hello guys!
If you buy the global version you don't need to root your phone to get lte band 4, even if that banddon't appear in the manual that come in the box, this is what happened to me:
I setup the phone the first time with out the simcard, and in languaje options just appeared spanish (united states) and spanish, I selected the first one, and.... I only had 3g when I installed the sim card. So I decided to reset the phone, but this time I did it with my lte b4 compatible sim card (at&t México) inside, this time "spanish (México)" appeared in the languaje options! and guess what? now I have 4G! so to have 4g in México you need to select mexican spanish in the initial setup, you can't select it in the menu options after the setup if you select another languaje in the initial setup.
Hola chicos!
Si compran la versión global no tienen que rootear el telefono para tener la banda 4, incluso si en el manual dice que no la tiene, esto es lo que me paso a mi:
Yo configure el teléfono sin la tarjeta sim dentro la primera vez y en opciones de lenguaje solo aparecía Español Estados unidos y Español, yo elegí el primero,y..... solo recibí 3g cuando inserte la tarjeta sim. Así que decidí resetear el teléfono, pero esta vez lo hice con una tarjeta sim compatible con lte banda 4 (at&t México) dentro, esta vez me apareció la opción de "Español (México)"!¿Y adivinen qué? Ahora tengo 4G! Así que para tener 4g en México tienes que elegir español mexicano en la configuración inicial, no puedes elegirlo en las opciones de menú una vez hayas seleccionado otro idioma en la configuración inicial.

Hola amigo que tal, de verdad funciona!!!, yo tenia el mismo problema, no me podía conectar al 4G en banda 4, he restablecido a fabrica y seleccionado el idioma "Español México" y ahora funciona sin problemas, actualmente uso AT&T, pero he probado con una SIM de Telcel y también funciona sin problemas (AT&T - Telcel ambos usan la banda 4) No es necesario ser ROOT.

Hi, my friend, that really works !!!, I had the same problem, I could not connect to the 4G in band 4 here in Mexico, I have made a factory reset and selected the language "Spanish Mexico" and now it works without problems, currently I use AT&T, but I have tried a Telcel SIM and also works (AT&T - Telcel both of them use B4 here in Mexico), is not necessary ROOT. attached SS :good:

This is what the vendor I bought my A1 from says: Tips: "The manual is universal and perhaps you can not find B4 bands in the manual, please update the phone and normally it can use the B4 band with 4G network."
Have you tried updating over WiFi first? I haven't received mine yet. I'm going to update over WiFi and then see if I can get an LTE connection.
Lol...the price increased since I made my order.

First, sorry for my english...i´m from Ecuador....I was using CLARO Network..but only with 3G.....I installed the september update and didn´t do a full reset...only changed the lenguage to Español (Ecuador) (deleted all other lenguages)...restart...and now I have 4G....thanks a lot!!!

I live in Puerto Rico and use T-Mobile. I had to change the language to spanish mexico and now it connects to LTE Band 4. Speeds are slow right now because the communication towers are devastated due to hurricane maria. Once they restore power to the Island I show be able to see regular speeds up to 80mbps

OnePlus 7 and VoLTE

Hi, I have an OP 7 (gm1900 with the latest AA firmware) and my VoLTE doesnt work.
I live in Mexico (Telcel carrier, bands 4, 5 and 28) and the 4g+ works fine but the VoLTE doesnt work.
When my phone arrived to me ir doesnt had the VoLTE option in the SIM settings so I installed a OnePlus LogKit apk and from there I activated the switch for VoLTE. Restarted the phone but i doesnt work.
My previous phone was an unlocked Umidigi Z2 Pro and the VoLTE worked flawessly, just inserted the SIM and the stupid phone showed the VoLTE icon on the taskbar (even after a couple of hard resets the phone recognized the SIM as a VoLTE capable).
Any help for my problem?
Thank you ?

Maybe try mailing your service provider. It wasn't working for me too and I mailed mine and they activated it from the backend.

Thank, i had solved my problem. Thank you

Yo tambien tengo el GM 1900 version China y no tiene banda LTE 4 (1700/2100) por lo menos eso no figura en la caja y tampoco me levanta LTE. Alguna idea? Gracias!
I also have the GM 1900 Chinese version and it has no LTE 4 band (1700/2100) at least that does not appear in the box and does not raise me LTE. Any ideas? Thank you!

Vato, TODOS los OnePlus 7 traen la banda 4. TODOS. Ya sea la versión China o la global traen la banda 4. Algo está fallando por ahí con tu celular.
Vato, ALL OnePlus 7 bring band 4. ALL. Either the Chinese or the global version brings the band 4. Something is failing around with your cell phone.

Tienes que seguir las instrucciones del post que te mandé. A parte del LogKit necesitas otras cosas que están en el post. Chécalo bien y me avisas que onda.
You have to follow the instructions in the post I sent you. Apart from the LogKit you need other things that are in the post. Check it well and let me know what's up.

Si. En Android 10 y en Android 9 fue el mismo procedimiento.
Necesitas el logkit actualizado para activar el switch del VoLTE.
Necesitas el apk del engineer mode para activar otro parámetro.
Y necesitas seguir el procedimiento del post que te mandé: instalar los controladores de Qualcomm (están en el post) instalar una app que se llama QPST y seguir el procedimiento del post.
La neta es una mamada, activas bien fácil el VoLTE.
Avísame si pudiste o nel.
Yes. In Android 10 and Android 9 it was the same procedure.
You need the updated logkit to activate the VoLTE switch.
You need the engineer mode apk to activate another parameter.
And you need to follow the procedure of the post that I sent you: install the Qualcomm drivers (they are in the post) install an app called QPST and follow the procedure of the post.
The net is a blowjob, you activate the VoLTE very easily.
Let me know if you could or nel.

For me worked with Row and UK telefonica.
Also you need that your sim card already have the VoLTE active.
For example, before my OP 7 I haved an Huawei purchased directly from Telcel and in that cellphone i already have VoLTE. Then i purchased an unlocked Umidigi, swaped the sim card and VoLTE worked from the first Time.
A mí me sirvió conla configuración Row y ahorita lo traigo con UK Telefonica (la que se menciona en el post de la configuración). Ahora, tienes que tener en cuenta que la sim que estás usando en el OnePlus tiene que tener activo el servicio de VoLTE. Por ejemplo, antes de mi OP 7 yo tenía un Huawei que compré directamente en Telcel y me dieron una sim nueva con el VoLTE activo. Después esa misma sim la pasé a un Umidigi y el VoLTE funcionó sin problemas. Esa misma SIM es la que traigo ahorita en el OP7.
La sim que tienes en tu OP7 ya tenía el VoLTE activo? O sea, tu teléfono anterior ya tenía VoLTE?

It is unlocked but disconnected from the network

Hello and greetings from Mexico.
A couple of months ago a friend brought me an S20 Note Ultra, and it is not the first time that he brings me cell phones for the family, the detail of this equipment is that it is unlocked but after a second it sends the message that is placed in the image [Change Carrier], I would like to know what I could do to be able to use the equipment since it was for me and I have not been able to use it.
I know about flashing roms, but I stopped doing them about 4 years ago. If someone could give me an idea of what to do, I would appreciate it.

He will not let me make the call from Mexico and the person who gave it to me says that he has already contacted them but that they did not give him a solution

No, it is not unlocked. The message that you are seeing means that it is still SIM locked to Verizon.
No, aun no esta liberado. El mensaje que aparece quiere decir que aun acepta las SIM de Verizon solamente

General BBVA Go PAY

Hello, I tell you that I was able to make NFC payments work with the BBVA GO Apk in Argentina, I comment on why I think that in Latin America, it saved Chile, Brazil and Mexico, there is no application to use NFC Pay. If someone is interested, I can tell them how I did or create a post, since there is no post for Latin America. Best regards Miguel.

Hello Miguel I’m interested in using such apk, itll work in Mexico?

Hola buen día, me imagino que hablaras español. Lo primero que debes averiguar es si el Banco BBVA en México permite agregar tus tarjetas de débito/crédito en un Smartphone con NFC para pagar con la app BBVA GO con dicho Smartphone.
Si esto está habilitado en tu pais vas a poder hacer lo mismo con el smartwatch.
Hoy a la tarde armó el post de como lo hice funcionar en el Samsung galaxy watch 4. Pero todo depende si la app BBVA GO está habilitado en México para cargar tus tarjetas en la app y usar un Smartphone para pagar.
Saludos cordiales Miguel
