[HELP] WCDMA Not Working On G530T1

Hello. I got a fairly used G530T1 MetroPCs. Calls and data works fine, only problem is 3G(WCDMA) won't work. If i change preferred network settings to WCDMA Only, the network signal goes off totally. I've flashed most stock ROMs and custom ROMs i can find here, but the problem still persists. The SIM works fine on other phones, so it is not the SIM card. I have tried other SIM cards too, still the same problem.
Anybody with a workaround or a fix should kindly help me out. Thanks

My G530T (T-Mobile) doesn't connect to 3G or 4G, only to LTE. I think that's just due to the hardware.

I thought that the MetroPCS version didn't come with WCDMA support. Many devices only support GSM, and because this device was never meant to run on WCDMA networks (Metro is GSM only), you might not be able to have these bands. However, if this is not your main device, and the phone is unlocked, you could try flashing an odin file for another version of the Grand Prime. MAKE SURE that your grand prime has the same chipset as the file your flashing, as some grand prime devices have a different chipset. Also, you might have to use a patched version of odin, which is all over xda.

Not getting the enhanced 4g LTE mode option in my settings.

So I got my Airtel number ported to a Jio sim card. Put it on sim slot 1. I'm getting to use data services but cannot seem to activate volte/enhanced 4g mode to make calls at all. The option isn't even visible in the mobile networks menu.
I also checked my sim info and it says 'volte provisioned' but there's volte option in the settings.
Since I'm not able to activate volte, each time I try to call from the Jio sim, it fails.
Also, I'm running the stock debloated ROM from Sandy and I'm rooted.
I've used V1 of this ROM before and volte was working fine. I just wasn't rooted at the time. Can root be a problem? Please help guys.

found anything ?
hey man did you find any solution to this problem yet?

Same issue- stock rom unrooted Airtel only
Quote me or hit thanks if you find a solution so I get a notification

Kenzo is not for airtel. It will never get volte.
Use Aosp Extended Pie.

Thank you for your reply,i didn't know that Airtel doesn't supports kenzo.
Okay,then is there any rom that supports dual 4g? Because ryt now i hv my airtel in sim 1 and jio in sim 2 with volte working...but whenever i need to call with Airtel ..my data needs to be switched to sim 1 that is of Airtel to make calls...n in this process...jio sim shows no network.
So what i want is a rom that could handle jio(volte) and airtel(non volte but 4g) at the same time so that i could use internet through Airtel 4g n at the same time receive calls through jio volte.
Help me find such rom.

I dont have airtel sim. But have u ever get that feature in miui global romfor kenzo ???
If u use 4g in one sim then other sim will fallback to 3g.
And also u must use same sim for data which u using for volte.
U cant use one sim for volte and other sim for data. U cant do this for kenzo.
If u want that kind of stuff then buy latest phone which has dual volte dual 4g.
