I got the XT1042 working On T-Mobile and At&t but the signal that I get for AT&T is so weak that it can barely be used. Can I flash the modem from the XT1045 to the XT1042 and would it help?

[Q] Can the modem from XT1045 be flashed to XT1042?

How?
How did you get it to work on T-mobile and At&t? I accidentally bought an xt1042 motherboard and have been trying to do the same thing with no luck. I did flash the at&t stock image from an xt1045 as part of my attempt, and that is what the phone is on now and it seems to be working fine. At one point the phone was being recognized as an xt1045 when connected to the computer, but I don't remember what made it do that.

I used the QUALCOMM BAND UNLOCKER guide here on XDA to unlock the GSM bands and then set the phone to RUIM Only using DFS. This is the band reference that worked for me the best: 562950069289863. If I unlocked too many bands the phone did not get a signal. Since we can get the diag port to show up by booting into BP Tools mode, most of the guide is not needed. Only the QPST and RV_NV_Manager.exe part to read/write the bands after getting the reference number from mzTool_1.2.1a.exe.
I hope this helps.
Oh and the SPL/MSL was 000000 for this model.

I've tried flashing different basebands from the xt1045. It never shows a change in the about phone. On a whim I flashed a radio from the xt1032 I think. The difference here was that it was a flashable zip. After trying that the baseband did change, but it just said unknown. It didn't work, but it's better than it not changing at all I think we might need someone with an actual xt1045 to make a flashable zip of the modem for us. That MIGHT work.

Mine is now working completely. Or at least it seems to be. I have 4g LTE with an at&t sim card, and I've verified calls and texting. My device is recognized as an xt1045 when plugged into the computer, and I'm running a rooted at&t rom. I used your settings for the band unlock and flashed the at&t stock rom. Pretty cool haha

When I unlocked the European bands the phone would not get a signal on US bands. I am not sure what caused this. The only way to know if it will work is to get one in Europe and test it.
I am currently at Europe and I would like to do the test but can I roll back the operation if something goes wrong? For example phone will not get signal on US and EU bands for some reason?
I was able to roll back by putting the default bands back into the NV item.
So before you write the new bands to your NV take note of the default bands that are there and if you do not get a signal then write the default bands back to your NV.
I have done this on several different phone models and after putting the defaults back, the phone worked just as it did before any changes were made.
just be sure not to change anything else. Only the bands in the NV item specified in the guide.
Ok I have written the band pref but how do I set it to ruim only in dfs this is the first time I've ever heard of dfs pls lol
Once you have the phone connected to your PC with a diag port, open DFS and choose the port for your phone.
Send SPC as 000000 (all zeros)
Cleck Read next to the Ruim Config, just to see what it is set to, then change it to RUIM Only and click write.
I also found that you can get a signal lock on T-Mobile towers much better and faster if you flash the phone to RETUS_XT1045 4.4.3 or 4.4.4.
I did not need to set it to RUIM only after flashing this firmware to the phone. I only needed to set the bands.
if you have problems keeping a connection then try this band reference instead: 101188096.
This band is only for T-Mobile USA frequencies. I still can not get it to connect to AT&T USA towers.

Is there any program to check the working bands?
Like this in the screenshoot on first page. I don't know the name.

it looks like they are using *#*#SERVICE#*#* (*#*#7378423#*#*) to see this on the phone.
I do not know any program to get this info. It would be nice to know though.
By the way how did you flash the rekus xt1045 firmware. I prefer fastboot an idk much else
When dialing *#*#7378423#*#* the phone does nothing. It seems that this also blocked as other commands.
There is another way to access the service menu?
Not that I know of. I never used it myself. The mztool shows the bands that you are trying to activate and testing the phone with active sim cards shows me which networks it gets GSM, WCDMA and LTE on. Even if the bands get activated they may not work. It depends on what the phone is capable of right?
