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).

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.

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
Hi!

Hi, so i made a research (a very deep one) and compare my cellphone with another J4.
The result is that my mobile dosen't show the option, but the other does, hence, it's looks like the problem is with my mobile.

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.

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

Hello, i need help. I try to install twrp and the phone now is bricked. No fastboot mode just go to recovery, that what show in adb devices. I can´t do anything because is in black screen.
Can anyone help me?
And sorry if im in wrong tread.
Thanks
It's resolved. I use adb shell to remove some files.
Thanks anyway,
Hello there, may i bother you time to teach me how to recover from your 9a bricked and just go black screen???
I already have this problem for almost 2 month and still can`t find the solution. Our difference was, i already install twrp and also already flash rom and suddenly its goes black.
Some simple solution that i read is, i drained dead my battery so need to charge it for a few hours, or maybe a whole day or two i heard. I already tried to charge it almost 3 days, still can get it to boot to fastboot or recovery.
And 1 more problem, my 9A only can be read by PC if I bypass the EDL using TEST POINT from my hardware, and i have tried many kinds of flashing tools and also downloaded a bunch or ROMs based on guides i read from forum here and there.
Please if you have the solution for my problem, it will means a lot to me.
Thx before.
cingcopa said:
Hola, ¿puedo molestarte para que me enseñes cómo recuperarte de tu 9a bricked y pasar a la pantalla negra?
Ya tengo este problema durante casi 2 meses y todavía no puedo encontrar la solución. Nuestra diferencia fue que ya instalé twrp y también flash rom y de repente se vuelve negro.
Una solución simple que leí es que se me acabó la batería, así que necesito cargarla durante unas horas, o tal vez uno o dos días completos, según escuché. Ya intenté cargarlo casi 3 días, todavía puedo hacer que arranque para fastboot o recovery.
Y 1 problema más, mi 9A solo se puede leer en una PC si paso por alto la EDL usando el PUNTO DE PRUEBA de mi hardware, y probé muchos tipos de herramientas de actualización y también descargué un montón de ROM según las guías que leí del foro aquí y allí.
Por favor, si tiene la solución para mi problema, significará mucho para mí.
Gracias antes.

Hello, from my understanding, if you can enter EDL, you could make a full reflash with SP Flasher, to revert to factory !
I have a slightly different problem, my 9A is in a bootloop, not possible to enter fastboot, no recovery.
I would like to use SP Flash tool, but i don't know the EDL hardware test-pins.
Please share a picture of the EDL hardware pins, if you know how to force enter EDL without adb/fastboot/twrp.
Thanks.

Hello,
I don't understand the meaning, you sent 3 pics containing a tweezer.
Was that a joke, sarcasm, or misunderstanding?
I had the impression that you already know the EDL test points for Redmi 9A.
I was just asking for a PCB picture with the EDL points marked for Redmi 9A (example I found for 9T, but PCB looks different : https://www.edlpoint.com/wp-content/uploads/2021/08/mi-9t-test-point.jpg)

"Please share a picture of the EDL hardware pins" from my understanding is that u are asking for hardware i used to by pass the edl mode. So sorry if im mistaken, im still newbie here. So forgive me if i misunderstood what u mean.
And btw, if you had the impresssion that i already know the EDL test points for Redmi 9A, why you still ask for the picture???
Was that a joke, sarcasm, or misunderstanding???
Nevertheless, here is the picture u asked for sir.
Good afternoon! Greetings from Mexico! A few days ago I bought a Realme GT Neo 2, I currently live in Mexico and use a company called "Bait" from Altan Redes (which uses band 28), this information will help me to explain and comment on a question that I have AND I CANNOT SOLVE.
According to the Realme website, my phone is the "realme GT NeoFR(12+256)" version; what I suppose is from France and therefore a version of Europe, so far everything is fine, right?

Well, not because according to the manufacturer's specifications, this super cell phone supports VolTE and supports band 28; when inserting the sim that I have in a OnePlus 5 from the Mexican company Bait with the hope that the VolTE will be activated and I can receive calls or dial, something that for 10 days I tried in a thousand ways and I could never activate said service, call operated and they told me the following "Your equipment is not approved to work with our network" pfffffff!!, and it is curious that said activation option does not appear in the settings.
How do I "half" solve this problem, since it is a dual sim, buy and enter another "BAIT" sim with activated data and use my previous "BAIT" sim, degrading the signal to 2g so that calls can come in and out.
So far I would like to know if anyone has a solution to this problem or has had the same problem that I face.
After reading here on XDA I did the following:
Firstly, the equipment came with the firmware RMX3370_11_A.03; and when reading in detail in the forum I realized that if we use a VPN it is likely that it will release an update to be able to unlock the bootloader and be able to flash the phone and change the region (with this flashing I thought that it could activate the volte or some functions different to be able to use my phone with the "BAIT" operator).
For this first Update I used the psiphon Pro application and the country of France.
https://psiphon.ca/es/download.html
After trying a vpn and a lot of patience the phone first received the RMX3370_11_A.05 update.
After a few days I kept trying to upload the version of the phone and simply with the vpn for hours and connected to WIFI I did not receive anything, that is why I thought what if I change the country when using the VPN? and bingo I was able to update to the RMX3370_11_A.06 version for this case I used the same application but using the vpn of the country of Bulgaria.
With this update it was first possible for me to unlock the booloader following in detail the tutorial of the brother @RMX3370 (thanks for the tutorials)
https://forum.xda-developers.com/t/...2-rmx3370-all-variants.4391679/#post-86396489
Once the bootloader is unlocked install TWRP and Magisk to root the phone; again following in detail the tutorial of the brother @RMX3370
https://forum.xda-developers.com/t/rooting-realme-gt-neo-2-rmx3370-all-models-with-magisk.4392005/
After this process and with the unlocked bootloader flashie and change regions through Europe, India Latam etc.... NOTHING OR ANY version of firmware activated the VolTE.
For flashing, follow in detail the following tutorial from brother @SrCDA:
https://forum.xda-developers.com/t/...ion-relockbootloader-realme-gt-neo-2.4399223/
All this process BooLoader unlocking, flashing, firmware installation (region changes) was done under MacOS BigSur without problems; That's why I tell you to follow all the guides in detail since I see that sometimes they ask many things recursively when the same authors of the guides solve them in the publications.
After trying and trying to get the VolTE to work I have resigned myself to staying in the INDIA region and I am already using the phone for daily use; only now there is another problem THE FINGERPRINT READER DOES NOT WORK, I have tried to put my fingerprints and it is really annoying to unlock it with a code; I have disabled magisk's biometric authentication BUT IT HAS NOT SOLVED ANYTHING.
I've changed the android calling app to avoid the "This call is being recorded" announcement, and uninstalled apps that slow down the phone to leave the stock rom as clean as possible.
It is a fast phone, well configured and I really like it; but I list my problems again:
- There is no VolTE for band 28 of Mexico
- Issue with fingerprint reader shaking when trying to add them to unlock the phone.
Note: if any user requires that I support him in something with all pleasure!; If anyone can ask for my listed problems or faced the same thing and managed to fix them, I would really appreciate some tips to finish configuring my phone!
Thank you very much for reading and for your kind attention, greetings from Mexico!

hello! Good morning, greetings from Mexico, it's good to know that at least I'm not the only one with the problem of activating VolTE, thanks for responding, comrade! Hey can I ask you if you have problems with fingerprint unlocking?

nope, fingerprint unlocking works perfectly for me
mine also came with the version rmx3370_11_a.03 I'm trying to update but I can't, even with vpn and changing regions I can't, is there anything else I can do? I couldn't find it in the Ota file to install

Ah yes, Aliexpress, that explains the strange version it came with -- Is there no way to flash a.06 using EDL?

I already did a search, I found the version rmx3370_11_a.06, but the instructions themselves I didn't understand very well. I tried to do it in OTA, but I couldn't find the file. I can even try to do it in EDL, but this is not considered root? Apart from that I came to look for update patches after the wi-fi gives problems of not finding the network, being that other cell phones are connected to the wifi network

I just got the phone myself so I haven't started with modifications or unlocking bootloader but considering its a SD 870 I would assume it might be similar to a Oneplus 7 Pro EDL procedure which requires a different button combo and different USB drivers from Qualcomm. The page I found here seems to show similar steps https://realmefirmware.com/how-to-flash/ and the download for global a.06 and india 1.07 [https://realmefirmware.com/realme-gt-neo2-5g-firmware/]
But I won't be doing that yet but from my own experiences on other phones it looks like the right path. Lots of people in other threads are mentioning inconsistent functionality so there might be more to it too. I guess it might be beneficial to keep watching and waiting.
My phone is from Banggood I'm on a.06 from purchase. I am in Australia.
I understand, well I even thought about buying from Bangood, but I didn't have it in green, lol, apparently it's the right way, but MSM doesn't accept my login credentials.Even if I were to do it now, I wouldn't notice, and even because I have to back up all the files, Irati get my old cell phone for this and format this one and try to do it. I hope to keep in touch with you, as you seem to be experienced

Even a Poco F3 has a similar method, however instead of Qualcomm EDL Mode, it uses a similar but branded Xiaomi tool and within Fastboot Mode to flash the device.
I'll be reading up on Stock flash methods for myself before I get to a stage where I unlock bootloader and root.

I researched, I really saw that it is a tool for xiaomi, the same and for realme/oppo, can you give me a contact so we can talk better? like telegram?

Wouldn't be the same no, as Xiaomi's tool only supports a fastboot type package.

Hi, I bought this phone 3 days ago (with no volte option) and Im also with BAIT. The thing I did is to download Vozapp, so far I can receive phone calls without any issue. When the phone stay along time without usage (like going bed) you may need to wake it up again (just double tap to wake the screen) so the app resume receiving calls.

¡Buena tarde! ¡Saludos desde México! Hace unos dias compre un Realme GT Neo 2, actualmente vivo en Mexico y uso una empresa que se llama "Bait" de Altan Redes (que usa la banda 28), esta informacion me ayudara a explicar y comentar una duda que tengo Y NO PUEDO RESOLVER.
Según el sitio web de Realme, mi teléfono es la versión "realme GT NeoFR (12+256)"; lo que supongo es de francia y por lo tanto una version de europa, hasta aqui todo bien no?
View attachment 5537279
Pues no porque según las especificaciones del fabricante, este súper celular soporta VolTE y soporta banda 28; al insertar la sim que tengo en un OnePlus 5 de la empresa mexicana Bait con la esperanza de que se active el VolTE y pueda recibir llamadas o marcar, algo que durante 10 días probé de mil maneras y nunca pude activar dijo servicio, llame operado y me dijeron lo siguiente "Tu equipo no esta homologado para trabajar con nuestra red" pfffffff!!, y es curioso que en los ajustes no aparece dicha opcion de activacion.

Como soluciono "a medias" este problema, ya que es dual sim, compro e ingreso otra sim "BAIT" con datos activados y uso mi anterior sim "BAIT", degradando la señal a 2g para que puedan entrar y salir llamadas .
View attachment 5537289
Hasta el momento me gustaria saber si alguien tiene solucion a este problema o ha tenido el mismo problema que yo enfrento.
Después de leer aquí en XDA hice lo siguiente:
En primer lugar, el equipo venía con el firmware RMX3370_11_A.03; y al leer en detalle en el foro me di cuenta que si usamos VPN es probable que lance una actualización para poder desbloquear el bootloader y poder flashear el teléfono y cambiar de región (con este flasheo pensé que podría activar el volte o algunas funciones diferentes para poder usar mi teléfono con el operador "BAIT").
Para esta primera actualización utilicé la aplicación psiphon Pro y el país de Francia.

https://psiphon.ca/es/download.html
Después de probar una vpn y mucha paciencia, el teléfono recibió por primera vez la actualización RMX3370_11_A.05.
Después de unos días seguí intentando subir la versión del teléfono y simplemente con el vpn durante horas y conectado a WIFI no recibí nada, por eso pensé ¿y si cambio de país al usar el VPN? y bingo pude actualizar a la versión RMX3370_11_A.06 para este caso usé la misma aplicación pero usando el vpn del país de Bulgaria.
Con esta actualización primero me fue posible desbloquear el booloader siguiendo en detalle el tutorial del hermano @RMX3370 (gracias por los tutoriales)
https://forum.xda-developers.com/t/...2-rmx3370-all-variants.4391679/#post-86396489
Una vez que el cargador de arranque esté desbloqueado, instale TWRP y Magisk para rootear el teléfono; nuevamente siguiendo en detalle el tutorial del hermano @RMX3370
https://forum.xda-developers.com/t/rooting-realme-gt-neo-2-rmx3370-all-models-with-magisk.4392005/
Despues de este proceso y con el bootloader desbloqueado flashie y cambio de regiones por Europa, India Latam etc.... NADA NI NINGUNA version de firmware activaba el VolTE.
Para flashear, siga en detalle el siguiente tutorial del hermano @SrCDA :
https://forum.xda-developers.com/t/...ion-relockbootloader-realme-gt-neo-2.4399223/
Todo este proceso de desbloqueo, flasheo, instalación de firmware (cambios de región) de BooLoader se realizó bajo MacOS BigSur sin problemas; Por eso les digo que sigan todas las guías al detalle ya que veo que a veces preguntan muchas cosas recursivamente cuando los mismos autores de las guías las resuelven en las publicaciones.
Después de intentar e intentar que funcione el VolTE me he resignado a quedarme en la región INDIA y ya estoy usando el teléfono para uso diario; solo que ahora hay otro problema EL LECTOR DE HUELLAS DACTILARES NO FUNCIONA, he intentado poner mis huellas dactilares y es realmente molesto desbloquearlo con un código; He desactivado la autenticación biométrica de magisk PERO NO HA SOLUCIONADO NADA.
Cambié la aplicación de llamadas de Android para evitar el anuncio "Esta llamada se está grabando" y desinstalé las aplicaciones que ralentizan el teléfono para dejar la ROM original lo más limpia posible.
Es un teléfono rápido, bien configurado y me gusta mucho; pero enumero mis problemas de nuevo:
- No hay VolTE para la banda 28 de México
- Problema con el temblor del lector de huellas dactilares al intentar agregarlas para desbloquear el teléfono.
Nota: si algún usuario requiere que lo apoye en algo con todo gusto!; Si alguien puede preguntar por los problemas enumerados o se enfrentó a lo mismo y logró solucionarlos, ¡realmente agradecería algunos consejos para terminar de configurar mi teléfono!

As far as I know MSM is paid brother, better use the tutorial described above since I currently managed to update (first Flashing to RMX3370_11_A.07 (Indian region) and I got the RMX3370_11_A.08 update

ok brother I understand, I don't use voice app better buy another bait sim and with that I have activated 4G and my main sim (also bait), what I was able to investigate with a friend who works at Altan Redes IS THAT THE VOLTE FOR CALLS WILL NEVER WORK ON THIS PHONE UNTIL REALME OR ANY MEXICAN TELEPHONE COMPANY SELL IT IN THEIR OFFICIAL STORES SO THAT THE TAXES ARE PAID AND IT CAN BE APPROVED

Hello brother, a pleasure! I recommend you try to flash it yourself to upload the firmware, when my phone arrived it had the same RMX3370_11_A.03 and it uploaded by itself without vpn or anything to RMX3370_11_A.05, from there I unlocked the bootloader and I was able to flash it by trying different regions, India, CN, Global etc...
