Troubleshooting Phone problem

Hi. Currently my g3 prophet works only as a pda The phone function doesn't. It is somehow unable to detect any network. Does anyone know how to confirm whether if this is a hardware problem or a software problem.
I don't know whether if it is because I switched roms. Bad news is I don't have my original rom...which is the dopod 818pro here in malaysia. I've tried several radio roms too and no luck with those eithers which leaves me to think that it could be an hardware issue.
Hopefully someone might be able to help me out without maybe troubleshooting steps for a newbie. Thanks in advance.
I want to add that i tried opening the SIM manager to see if it is a sim card connection issue and I'm able to see the sim card properties, ie like the memory size and so on which to me means that the unit can speak with the sim card.

I've already flashed to the most basic rom which is an original that is from the wiki and tried all the available radio roms below.
RUU_Prophet_220734_2207114_024721_QtekWWE_Ship
Prophet_G3_G4_RadioRom_v2.07.20.exe
Prophet_G3_G4_RadioRom_v2.19.21.exe
Prophet_G3_G4_RadioRom_v2.20.21.exe
Prophet_G3_G4_RadioRom_v2.30.21.exe
Prophet_G3_G4_RadioRom_v2.47.21.exe
Prophet_G3_G4_RadioRom_v2.61.21.exe
Prophet_G3_G4_RadioRom_v2.69.21.exe
Am I missing any other things that i need to do/try?

Ok.After spending a whole day trying to figure out whats wrong...I tried a different sim(from a different service provider) which now works.
At first maybe I thought it would be sim locked so I got hold of lokiwiz to unlock. However after running the program, it tells me that the phone was never locked.
So now I'm back to square one. Does anyone else from Malaysia have this problem? I'm trying to use Maxis (which doesn't work) while inserting a Digi one will.

hmmm strange. bought mine in malaysia as well. no problems after i upgraded radio roms & also touch 7 & 8. works in malaysia, europe & now new zealand, roaming & using 'local' sim cards
phones in malaysia are never sim locked maaa AFAIK
maybe it is a sim card issue. some sims are 64kb & others are 128kb?

Yeah thats the thing...i KNOW that phones in malaysia are never sim locked but I couldn't think of any other explanation for the strange behaviour except that. I didn't think that sim cards could cause such issues as I am very sure other users must be using Maxis like with the prophet without a problem.

I've tried out a few different friend's sim cards (some of which are from the same carrier as i am) and it works. I guess something is wrong with mine although it works in their phones though. Some stupid compatibility issue? Never heard of this before though.

Vodafone UK, unbranded S7E, any way to get WiFi calling at all?

[SOLVED]
Please see this comment for how I weirdly got WiFi Calling.
Hi guys, signal in my house is horrific - I've been trying to get WiFi calling for ages, and loved it when I was with EE.
I'm now on Voda and don't have it.
From what I've seen, it doesn't appear to be possible with an unbranded phone (why Voda!?) through any normal/configuration means.
I have the option to turn it on under settings -> applications -> phone -> wifi calling, and I've sent 'CALLING' to 97888, but only get the confirmation of the text, and nothing to confirm it's been set up. However, I don't get the little icon to signify that I'm using wifi calling.
Is there any way I can get wifi calling?
Does it require flashing?
If I'm going to have to root/flash anyway to get this feature, is there a way to do it one of the nice custom ROMs I see on this forum, but retain the vodafone branding?
Thanks all.

Easiest way is to flash a Vodafone firmware. Had to do the same to get EE WI-FI calling working. There is an option in unbranded firmware but activating it does nothing

Just flash latest Vodafone firmware that way you will not trip knox and you should get wifi calling

I suggest you check with your provider, if the unbranded phone was not bought from them.
Wifi calling may not be allowed because the imei is not registered to a vodafone branded phone.
They may have blocked the wifi calling feature.

Hey,
I've got the Google Pixel phone which I bought from Carphone Warehouse. Vodafone have told me that WiFi calling should work with it without any special firmware. I've tried using my SIM card in a friend's Samsung Galaxy S7 Edge which he bought from Carphone Warehouse and it worked! I too didn't get a text message from Vodafone when I texted 'CALLING', but WiFi calling is now active on the SIM card, albeit not the phone. Have been in discussion with Google who have escalated my problem to their technical people. Hope it can be resolved very quickly, otherwise returning the Pixel, which I don't want to do.

Thanks very much for the replies guys - I have something to report back to you all too. Unsure HOW this happened, but it happened... I somehow got WiFi Calling.
I'm scared to try do anything else like switch off my phone, because I don't want to lose my new WiFi Calling.
Here's what happened:
I have an EE iPhone 5s, locked to carrier. I'd recently requested an unlock from EE. It had been switched off, and was recently hard factory reset. Unsure of iOS version.
I put my Vodafone SIM in the iPhone today to see if it had been unlocked... it hadn't. SIM was in there for roughly 1 minute.
I put the SIM back into my S7E... started getting the usual texts from Vodafone about changing SIM, blah blah.
Somehow, I now have WiFi Calling on my unbranded S7E on Vodafone!
At no point did I switch off my S7E during SIM changing.
*NOTE* I'm not sure if something has changed recently, but I definitely did NOT see the WiFi Calling symbol before I did this:
I have no idea why/how and I can only speculate.
But... there we are!
Not sure if anyone else can try/vouch for this, as I realise it's a VERY particular set of circumstances, but I hope this helps someone!
Please do respond to me if you try this out and get it working... it'd be interesting to see if it works for others, and maybe figure out why it works.
Cheers!

I need some serious help from the Smartest people. Sim unlock questions

Ok, I know this will be long, but I'll try to keep it short. Thanks again for your help.
I have an s7 sprint phone, after calling for two weeks and hearing the same tune, they unlocked my phone. I switched to tmobile and have a loaner phone even as of now because of stupid sprint. When I put the tmobile sim card in it says invalid sim card. So, I go to sprint and they said yes it is in fact unlocked. The guy seems really he wants to help, He can't get the t mobile sim to work also, matter of fact there is no options for network apn or nothing with the new t mobile sim card in. You have to put in the old sim card from sprint and there is the options. He even tried to some how change apn there on the spot by swapping sims while the sprint sim gave him options. He typed in all the t mobile info from t mobile site and it says unrestricted network. So he said its prob. sprints software locking the other networks. He said t mobile will have to flash it with their software. I go back to t mobile they have no idea what flashing even is. Unlike the sprint store they don't have a tech room with workers dedicated to working on phones.
SO, basically I'm trying to say my phone shows unlock on their side but i'm not to sure if it's showing it on myside. I can't use my phone at all i'm paying t mobile loaner j7 phone and stuck with an almost brand new s7 that either side has no idea. T mobile says its not unlocked over and over, sprint is saying it is unlocked.
I found a similar post at sprint, but it dead ended with nothing.. I can't post links, but by reading it you may understand more it's on the sprint site titled: samsung galaxy s7 edge SIM unlock
Thanks so much to whom ever can help. Have a nice day. I'm sizzling here

I have a Galaxy S7 N930P from Sprint that I use here in Canada. I ended up flashing the unlocked N930U firmware (the Sprint variant), and all works well now. No Sprint bloatware, full access to my APNs again, unlocked bands, etc. I had to get the new firmware from SamFirm (or Sammobile), connect phone to computer via USB, reboot to download mode, run odin, then flashed the BL, AP, CP, and CSC (not the home CSC...the other one) files in the firmware's .zip using Odin 3.12.7. Worked for me, and sounds like something that might work in your case too. Worth exploring at least

Try flashing the unbranded firmware or if you moving to T-Mobile you can flash the T-Mobile branded firmware too.

Sorry for hijacking the tread - what will happen if I flash Tmo or U firmware into locked Sprint phone?

First off, changing the firmware will not sim unlock the the sprint device, if you do flash to say a tmo branded firmware you will basically have a tmo branded device but still locked to Sprint. same thing applies if you flash the U firmware on a locked sprint device.
It's best to first have sprint unlock the device remotely then flash tmo or u firmware.

Vky-l29 with 8.0.0.386 (c432)... Canada?

I have been trying to figure out how to change to Canadian region. It was suggested to me that because I have the European rom on the phone, I cannot get wifi calling and volte calling. I cannot seem to find such a rom for the p10 plus dual sim.
Any suggestions?... Thanks in advance.

I was hoping when I received the update to PIE I would get VoLTE and wifi calling but still nope. I do not have the toggles to turn on for either function. My phone is not rooted.
I am on Freedom Mobile (and my wife's Samsung S8 works with it) but the techs say they cannot get it to work. I tried contacting Huawei and they said it is a carrier issue and the phone itself should work once the carrier sends the software. Freedom does not understand what that means.
Does anyone have VoLTE and/or wifi calling working on the VKY-29 p10 Plus? If so, how?

Yes, I have same model, with VOLTE and Wi-Fi calling working (not în Canada) . It is carrier related

That doesn't make make me feel better ...
I know 2 people with Roger's who do have the toggles ... I am going to try and borrow my colleague's SIM and see if it will update my phone. If it does, hopefully when I put in my SIM after, it will still have the toggles visible.

I have it. I'm in south Africa. Working on multiple carriers here.

Well I borrowed a SIM but no luck. I had them call into to Roger's but was told since the phone was not purchased at Roger's store they would not send the carrier.
So far, Freedom will not send the patch. Roger's will not send the patch. It seems Bell (as posted above) doesn't support. I will have to try another carrier. I will post if I find one that will.

Custom to stock for VS995 for UK use

I've been on AlphaOmega ROM and want to revert back to stock as I'm selling the phone but I'm a little stuck. I've downloaded what I thought was the correct ROM
VS99520c_01_1110_ARB00.kdz (region VRZ)
and then tried
VS9951AA_01_0122_ARB00.kdz (region VRS)
The reason I'm stuck is I'm getting a notification saying Verizon Wireless does not recognise my sim. I'm in the UK (imported from Hong Kong) and quiet happily have used the mobile network data & voice on various providers though probably not as well as a phone intended for the UK market. It's my own fault for not backing up the original ROM I know :crying:
The other thing is and I'm not sure if I'm imagining this but I'm pretty sure when it used to complain about the sim which it would after every reboot it would say Verizon and not Verizon Wireless and it would still manage to pick up the local bands. Now I'm getting nothing, nada!
So any pointers would be appreciated :fingers-crossed: Am I using the wrong ROM?
