[Q] Htc desire hd A1919 3G Problem

I am using HTC DESIRE HD A1919. (Baseband version 12.65.60.29U_26.14.04.28_M) and (Kernel version 2.6.35.10-g931a37e [email protected] #1 Wed Nov 9 14:04:03 CST 2011). Recently 3G is launched in my country Pakistan but when my phone is not connecting to 3G. settings/about phone/Network/Mobile Network type always shows EDGE! I inserted my sim in a friend's phone in the same area and 3G was working fine. I went to Htc Sales and Service Store but they simply said they can't help! I have never rooted rooted my phone and done nothing with my phone except downloading apps from Google play! Can anyone tell how to solve this problem??? Please tell the solution in steps because i am unaware of android development and stuff like that!

Did you get 3G while choosing WCDMA Only?
If Yes,means you have to do it manually everytime you reboot your device.
If No,means you don't have a 3G data plan.
If you reboot your device mean while it will again set to prefered WCDMA so everytime you need to do it manually. Just to remember if you're getting 3G even on prefered WCDMA then leave it as it is. I think it's an issue regarding weak carrier signal.

I have tried everything like this....but still no results! I guess this is a problem of build.prop! can anyone help in this regard?

Its not the build prop. Its how HTC designed the DHD.
The DHD isnt quadband, You can check the specs at gsm arena.
Some countries have thier 3g on a different band, so if you buy a DHD that doesnt scan for 3g on your countries band, you face the same problem.
I have being trying to fix this problem but got stuck along the way. Its very good to see that people also have the same problem. Maybe the devs would try something.

dear, did you get any sulution for 3g network on dhd?

Nope..
Before i can try anything i have to put the device in diag mode which i have being able to, but the problem now is the device isnt showing up properly in QPST(a program for communicating directly to the qualcomm chip).
It detects the open port on windows but its unable to find the phone in the port.
If the phone doesnt show up in the port, changes cannot be done.
So thats the update.
If you have any idea, you could share

WCDMA
goto mobile network under settings, then select network mode, change it to GSM/WCDMA auto if it doesnt work then change it to WCDMA only.
It'll do the trick.

Adding LTE band B38 (TDD 2600)

Hey XDA,
I've been following this tutorial for how to add some bands but my phone simply doesn't see any networks when scanning for LTE on band 38.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I'm running CloudyG3 2.5 with ChupaChups kernel.
Has anyone ever changed their LTE bands on a G3 (and succeded)?
Thanks!

I could not find the LTE on my phone with this SIM but when I inserted it in a OnePlus One I could browse in 4G. The SIM isn't the issue.

Nobody from all this smart guys that are here could not tell us how to make LG G3 to open band 38 on the LTE so we can get 4G internet on Digi Mobil ???? Right now since the android 6.0 update cant even access the hidden menu using that code.
Also another matter , since the root of Android 6.0 the micro SD card can not be recognized anymore.....don't matter what rooting you try the micro SD wont work no more. Nobody bother to fix this yet. Every one acts smart and writes here but all he does beat around the bush.
Awaiting for real answers.

Hi, I know that it has passed a long time since you've posted but here goes :
After trying to add band 38 to LG G3, i tried to update to Android 6.0, but couldn't because my phone was rooted. So i've flashed my phone to Stock ROM. If i remember correctly, my phone came with 5.0.1. Stock ROM is 4.4.2. After many, many updates i installed Marshmallow. Try to make all possible updates using the phone's software center, after that check with LGPCSuite if there are any other updates (they call it upgrades) and do them. Just like you i can't access the hidden menu anymore, and my micro SD card is recognized. Apparently after upgrading to Android 6.0 fixed it. (It shows 4G instead of H+ or 3G, now i only need to test the speed)

Is VoLte Supported on OnePlus 3 Stock 3.2.1 ?

VoLte from different service providers are going to be rolled out in India very soon. Is our Phone support VoLte feature?
Or shall we wait for another software update?
Any Custom Rom support VoLte feature at present ?
Pls reply

its supported in OOS 3.2.1
using JIO

I activate it (T-MOBILE Germany) and I can't find the settings in the menu [emoji20]
Any idea where to find?
Sent from my ONEPLUS A3003 using XDA-Developers mobile app

yes, but may depend on carrier, and it's worked since before 3.2.X for me
USA T-Mobile VoLTE works fine.
I've heard USA AT&T VoLTE isn't working yet though. Outside the USA don't know.

Not only is it supported, but you get this ridiculously stupid VoLTE icon in your status bar when you're connected! Hooray!

Yes its supported. Using JIO

Currently you can buy a LYF phone and you will get a JIO connection with it. But it will be locked to that specific handset.
To get a Sim free from handsetlock you need a employee/retailer demo sim.

Im using idea on Sim 1 and Jio Sim 4G on sim 2
Make sire you put the network type to lte on JIO and gsm on the other one.
If you choose LTE for your other sim, since the handset can only support lte fir 1 sim at a time it puts the JIO sim into gsm. And JIO has only LTE band. No 2g or 3g bands. Hence the network drops.

As far as i know. When you choose the mobile data sim in sim cards menu. The option of network type disappears from the settings of the other one. For example. Please look at the attached screenshots.

Yes thats true.. since u told me to set lte for jio sim and gsm for other sim i was confused. At a time only one data connection will be enabled. so i guess the frequent drop is not related to that. Do u face any issue with network drop? im using jio in slot 1 and after couple of hours the network drops and it goes to no network.

The data drops sometimes but comes back usually within seconds. If it doesnt i put on airplane mode and take it off again. That works. But its too rare. I use idea in slot 1 jio in slot 2

Network problem on ONE PLUS 3

I just brought a One plus 3 last week.
I m using jio in sim slot 1 and bsnl in sim slot 2.
If I select cellular data on the Jio sim, both sims have network. But if I select cellular data on Bsnl sim, jio does not get network. I m using on oxygen OS 3.2.6.
It is hardware or software problem?

thats probably because jio is a 4g only network and oneplus 3 doesn't support both sims running 4g at the same time.

That doesn't matter, you can only set 4g network on the sim that has an active data connection. Suppose you have idea and Airtel and both have 4g, which ever sim is your data sim will be able to have 4g access.

VOLTE(SIM-1) & 4G Data(SIM-2) Not Possible?!

Hey guys,
Just yesterday I came to know of this annoying problem with our device. For context, I use Jio as SIM-1 and Airtel as SIM-2. So what I was trying to achieve is to use 4G data from SIM-2 while SIM-1 was 4G & VOLTE enabled. But the irritating thing is this configuration as far as I tried not possible. Even searched all over XDA and ZUK forums for our phone and still no solution. While SIM-1 is the Data SIM, SIM-2 can still be 4G (but what's the frickin purpose). But When SIM-2 is the Data SIM, SIM-1 can't be 4G or have VOLTE flag. Then I thought if this is problem might be over if I interchange the SIMs in the slots. Now SIM-1 is Airtel and SIM-2 is Jio. Now also if I set SIM-1 to be Data SIM, Jio doesn't receive any frickin signal or VOLTE Flag. If Someone can please help me solve this problem, it would be very much helpful. Or I would like to know whether this problem is with a particular ROM only. I Run RR 5.8.4 with latest basebands and Darkmoon Kernel. Please Someone Help me with this.

Bro it's the same for any phone none have dual 4g standby and as you switch data sims the Airtel switches to 4g while jio gets downgraded to 3g where it can't work properly

I can confirm that.

And also I've checked three other phones (Oneplus 2, Mi Max, Le 2) where the phones donot completely lose signal (though happens rarely but a reboot rectified it). I think this is more of a ROM based feature than a hardware incapability. If anyone can confirm that this particular configuration of SIMs work on any other phone(s), we could probably port that feature atleast as a Magisk Module.

This is not a phone or ROM problem...its just that jio doesnt want users to use free voice while they are using different carrier for data!

Mi a1 getting dual volte feature via new software updates, so can't we?

Dual volte is successfully implemented on mi a1 with software and ours is SD 820 I think we can also enable it

Most 4g have backward support 3g.. so even though the phone is latched on to 4g it is actually connected to 3g bands.. true volte is only jio.. if volte switch is off and you are still making calls then it's backwards 3g that is gsm network

For me jio is volte first sim and Vodafone LTE on second sim.

can someone confirm me if airtel VoLTE is supported in their z2 plus even on single sim? I asked customer support of airtel and they said that our phone does not support VoLTE feature of airtel.
