Morning, fellas. I have a problem with my Poco F1 that I couldn't solve. I have looked for information in this forum, but I can't find information about it. Let's see if any of you can help me. It's about the following: The 4G/LTE network works everywhere with the official stable global version, but if I install a custom ROM on my Poco F1 (Lineage, Oxygen, Pixel Experience, etc) the 4G LTE works everywhere BUT IT DOESN'T WORK IN MY HOUSE ZONE, where it only connects to the H+ mobile network, even installing the latest vendor firmware through TWRP. I have tried it several times with different custom ROMs / vendor firmware versions. In fact, right now I have the rom Xiaomi.eu ROM, which is supposed to be based on the official one and I'm still with the same problem, I don't get the 4G LTE in the area of my house, but it works great in the city area. I'm in Mexico, with the Telcel network that works the 4G/LTE with band 4, also known as AWS, which uses a pair of frequencies for transmission: 1700 and 2100 MHz. Anybody out there to light the way to solve this?

Hi, i have a Moto E 2015 XT 1524, one friend bought it in Spain, but I live in Argentina and the bands are different, in Spain 3g works in 2100/900. In argentina 850/1900, so my movil only works in 2g... the question is if I flashing a new base band.... the 3g will be work?
Sorry for my bad english...
From what I understand, all Moto E models support at least 3G and some 4G. This is at the hardware level. Now your baseband is a firmware thing which will allow your device to communicate with phone towers in your region. So unless your firmware supports two or more bands, you most certainly will need to flash a new stock ROM for the region and service provider as needed.
To answer your question... If the new region you are flashing a new ROM for supports 3G, then yes you should get a 3G signal. If the signal is weak, then it may receive as 2G strength.
I am in the US where every service is at least 3G capable. So every smart phone is also 3G capable. But even still on my 4G version of Moto E I sometimes get a 2G signal. So it's hard to answer yes or no.
If you flash a ROM for Spain and get no signal, you have flashed the wrong ROM. If you flash a ROM and get 2G, then perhaps you are in a bad area with low reception.
In theory, you should receive the same signal as the people around you-Give or take a bar.
If 4G is supported in the area you want to move to and your device supports it as well, then you may very well get that signal too.
Does this help to explain it?
Thanks for your answer... In your opinion... If I flash a new stock ROM the 3g will be works? My model isn't released in Argentina yet... If I flash a firmware from UE my phone will be work?
Only if 3G is supported by the carrier in the region you wish to be. And assuming that the carrier is capable with the ROM you flash. Sometimes cross threading ROMs to a new service works. It all depends.
Thanks for your responses, the technical service told me: Bands Red 2G GSM / GPRS / EDGE 850/900/1800/1900
Red 3G bands UMTS / HSDPA / HSPA + 850/1700/1900/2100.
So I guess it will work if I change my stock rom. What I need is the XT1527 RM, is the United States and works in Argentina. How do I download it? ... And most importantly ... can I put this rom in my phone although the model is another? ...
Please... I need the xt1527 base band... Someone can help me???
Reflash a compatible stock ROM from the following link to fix your base band:

XT1527 is in this list

Hello!
I had a simillar problem with the XT1524. I also live in Argentina.
The XT model is international, so at a hardware level you have all the bands, but it is limited by the software.
The solution is (tranks to JasonPro11=:
1. Download "4G LTE Switch" from PlayStore
2. Run the app (does not require special permissions).
3. Go to "Set preferred network type” and choose LTE/GSM.
4. In the upper corner go to "Set Radio Band" and choose "USA Band".
5. Restart and enjoy LTE and 3G in Argentina...
I´ve also published this post in Grupo Android (spanish version).
Regards,
Fernando
I have installed latest AOSP CAF build but only EDGE is available, no 3G or 4G. Help with this matter is appreciated, if somebody knows how to solve it.
That happened to me too. With Simyo I could use 3G but I couldn't use 3G with Movistar, only 2G.
On Lineage, 3G works perfect with Movistar SIM.
Is it possible to flash modem only?
Hello,
I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India)
It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier.
Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM
I unlocked Bootloader flashed old MIUI version and rooted my phone
I installed Network Guru in that
for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2
When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

My kenzo has the same issue with China Mobile(China).
Failure at msg2 for band 38, band 40 and band 41.
Currently, I lock it down to band 39 to get it work.
I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine.
Tried to flash the original ROM and modify the NV with QTSP but didn't work.

I think its an hardware issue, replacing the motherboard might be the only way
Mi A3 Global version supports different LTE bands than the India version as shown in the information here
https://www.kimovil.com/en/frequency-checker/US/xiaomi-mi-a3
Is there a way to enable Global LTE bands as shown to be supported in the Mi A3 bought in India ? I am in the US and able to connect only to 2G network on T Mobile
I'm in the same boat. I'm in the US and have the EU version and I'm only getting H+ which I guess is like 3.5g instead of LTE. I wonder if flashing the international ROM will do anything. I'm going on a trip soon though so I don't want to be messing with this phone in case I brick it or something.

I might be a little late, but both the Global and EU ROMS/variants support same bands. I have global version flashed to EU ROM, and there is no connectivity difference. I use T-Mobile and get LTE most of the time (bands 2 and 4). I do wonder if it's possible to unlock/access other LTE bands (like 12,66,71)?
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
That is disappointing to hear as I have been looking into this phone and assumed it would have full usage on ATT.

I got volte to work on tmobile for anyone who is reading this later. Fairly easy to do after the pain of figuring it out was over. My data also fluctuates between 4G and LTE (4G+) as well.

How did you get T-Mobile to activate the service on your phone? They just tell me it's not compatible.

[Guide] Easy method to Enable Volte (with root) on Tmobile and maybe other networks on Android 11 and maybe 10
So first you have to root. I used twrp and magisk. There are guides on how to do that you can find by searching around. Then once you do that, follow these directions, What I did was manually entered all of these setprop commands below, on the...
forum.xda-developers.com
Sorry, thought you were asking about setting up Volte on the Zenfone 7, so I pasted that link.
To use this phone in TMobile, no special activation is needed. Just a tmobile sim that can handle voice / data.
