HELP????? i cant seem to get my phone working on gsm?

Dear friends
i have a unlocked HTC 8525 !! i am in brazil and can't get the sim card here working with my phone. i can see the sim menu and everything but the phone only says no service . i try'd to change the network under phone/menu/option
but i couldn't get it working , and the closest suppor for HTC is in Sao Paulo and im 600 miles away
Help me please

Hi DJFuscao,
I have an HTC Tytn that I regularly use in Brazil (Sao Paulo) since oct 2006.
I´m not sure if I will be really able to help you, but I´ll try to give you at least some information about my experience.
I believe that sometimes autodetect network does not work properly. You may try to change these settings:
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your Network type: change this to GSM
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your GSM/UMTS band: GSM(900+1800)+UMTS(2100)
I have also experienced some problems some months ago when VIVO activated their GSM network. It simply stopped working, kept searching but did not find TIM´s network.
What I have done then:
- I have changed from Automatic Network Selection to Manual (you will find this option on "Settings-->(Personal Tab)-->Phone-->(Network tab)--> Network Selection".
- then I tried to click on Find Network on the same screen
- I chose TIM from the list
It has not worked at the first atempt because there were some different options for TIM on the list but it has eventually worked.
Another thing I would check is if it works with any other GSM carrier from Brazil. If you can borrow a SIM from some friend this could also give you some clue.
You may also find some specific information about HTC 8525 phones in Brazil on the link below:

[Q] strange problem with 2G T-Mobile calls

Hallo everyone!
I've just bought my Verizon Droid Pro and at first day have big problem with it Maybe someone had similar and can help me.
When my phone is in 3G coverage everything runs OK but if it switches to 2G i'm not able to place any call. When i'm pressing the dialpad i can hear dtmf tones but when i want to connect i can't hear anything or the system reboots. When someone calling me i'm also unable to hear anything. Most interesting is fact when i put the SIM from antoher network problem gone. I not checked every providers but two different sim from T-MOBILE POLAND not working.
I've flashed back to 2.26, 4.68, CM7, 3Ghack and baseband switcher - NO ANY EFFECTS. In any rom cannot place any call in 2G mode
I called Tmobile and they told me there is standard 900mhz coverage the same like in PLUS (another poland provider which runs me without any problems in 2G)
Motorola Service tells me that they are able only to put european software in the phone ?! and US warranty is not working in europe
maybye someone have knowledge about RadioComm software - what can i test to chceck this bug
another question: if i put for example VRZ_XT610_4.6.8_user_signed_1FF.sbf by RSDLite5.6
is my radio settings back to stock or not?
I'm asking because i followed the steps in
http://forum.xda-developers.com/showthread.php?p=22816363
and wondering is these settings permanent or not.
maybye there is another radio file to flash there?
thanks in advance for help

[Q] [Help] No 4g / LTE option LG G2 D802

Hi, I cant seem to switch my phone to 4g / LTE. I've tried the various *# hacks like LTE only, but i only get 'Not supported'. Anyone else experiencing this? I was using 4g and getting 4g speeds on my N5. The phone was previously locked and I unlocked it straight away after receiving it.
The software version is D80210g-234-30

Anyone?

im also interested on how to fix this. anyone?

Turns out it was just a problem with the sim / network I was using (Tesco (o2)). When I tried with another 4g sim the options for LTE showed just fine

It was a problem with my network provider, nothing to do with the phone. Try another 4g sim from another network and see if you get 4g / LTE

I contacted LG today about the 4G issues that many experience and I thought I should share the official response:
Many Thanks for your email regarding your LG G2, I am sorry to hear you are experiencing problems in receiving 4G.
Can I just ask whom your network provider is? All main UK network providers bar a couple are receiving 4G via our handset, there are only a few 4G networks at the moment who are yet to approve the software on the G2. Please note it is not a limitation of the handset but is network dependent
The above will also explain why some other people in the area are getting it, their networks are almost certainly among those whom have approved the software on the G2 handset.
I look forward to your earliest response with the network provider, once received we should be able to clarify this for you.

So it seems it is indeed a carrier issue.

Hi, I have recently upgraded my phone to a sim free LG G2 also, and in doing so spoke to Tesco Mobile about receiving a new 4G sim to match my upgraded tariff.
This has all been put in place but I still have no ability to select LTE in the preferred network section. New APN settings were sent out by Tesco but this didnt make any additional setting options available, has anyone got any more info on this issue or advice?

You probably also have an non-EUR software version installed on your G2. Where did you buy it from?
If the above stands, the solution is to flash the EUR software version, although I haven't as I do not really need 4G for the time being. 3G is completely fine.

The handset was purchased from Expansys in the UK and the software is version D80220b-EUR-XX.
So I would not have expected that this issue would come up, it seems to be a unique blend of Tesco(UK) carrier settings and the handset software.
I won't be flashing any new ROM as a solution for a problem which sits with the carrier. Though I am keen to hear if any other users have found an alternative work around.

You already have a EUR software version, so you do not have to flash.
There is a problem with some carriers in the UK not approving the G2 4G software as I have stated above.

Had the same problem.
Changed the SIM for a new one (still labelled 3G 128k) and 4G is fine now (stock JB D802 SIM free).
My previous SIM was almost from the turn of the century (cut to fit microSIM)

I'm having the same problem, no LTE option, here's a solution:
Enter Android test menu by dialing *#*#4636#*#*
Go to Phone Information ... Set preffered network type ... f.e. to LTE/GSM/WCDMA ... if LTE is available, my phone switches to LTE ( showing 4G ) immediately without restarting.

This is what I did

Won't work with a non-US SIM?

I've been banging my head against the wall all day with this one and am pretty close to throwing my 6P out the window of the place I'm staying right now
My 6P is normally on the Verizon network, but I'm traveling to Italy for a bit so I grabbed a local carrier's SIM (TIM, doubt it matters), and my 6P refuses to connect to their mobile network - as in, no signal ever, emergency calls only. I put the same SIM in my friend's iPhone here and it works fine. I also put it in an LG G4 here and it was at least able to pick up a signal.
Here's what I've tried so far, unsuccessfully of course:
* "Reset network settings"
* Selected TIM in the network provider screen. I get the extremely unhelpful "No Service: Selected Network (I TIM) is unavailable" and "try again later"
* Selected Automatic in the network provider screen.
* Switched between 2G/3G/4G for the above two steps.
* Changing network bands in *#*#4636#*#*
* After doing more research on the bands problem, resetting them via the advice I found here and more importantly, here - I changed it back to Automatic band selection. Tried Euro too for fun, and it didn't work either.
* Factory reset on the latest 6.0.1 build
* Flashed N preview, did a factory reset
I know for a fact that the 6P supports the correct bands via this Wikipedia page. I took a quick look at the logcat and didn't see anything interesting, if anyone thinks it would be useful I can post it here.
What gives? Is my device hosed? Anyone have other ideas on what to try? Thanks!

I’m not sure about Italy but our n6p will work with non-US Sim. I just got back from China and Hong Kong and was using my USA Project Fi and two local carriers (3 and China Mobile) without any problems. Your issues may be carrier base. I did have some drop calls with the carrier 3 in Hong Kong and the set up with 3 was not as easy as China Mobile. I had the carrier 3 Sim installed at the carrier 3 store. But China Mobile installed just fine all by itself automatically as soon as I installed the Sim. You may want to have the local carrier TIM, take a look, I bet its something in the settings with the local carrier TIM.
Good Luck.

Yeah, I thought in general that it should work. Unfortunately I don't think I'm going to be able to go into a TIM shop since we're not near one and I doubt I could communicate the issue effectively given my broken Italian... thanks though!

Well, to anyone unlucky enough to have this same problem... I've made some progress! Of the two TIM SIMs we have, one seems to be enabled for 4G access while the other will only connect to 3G - not sure if this is by design or not. I put the 4G-enabled SIM in my N6P, wiped, and rebooted to Chroma and everything worked before even selecting "Automatic".
I tried putting the 3G-only SIM back in - back to no signal. I wonder if the band selection thing isn't working properly? My impression is that it's a 3G only setting and doesn't affect LTE connections, but I could be wrong. I am fairly sure the N6P supports the 2G/3G bands TIM uses around here...
If anyone has a clue on how to make a guide like this: http://forum.xda-developers.com/one-e8/help/signal-selecting-usa-band-4636-menu-t3091439 for the N6P that'd be awesome... not sure I will have time to experiment myself while in the area where it will matter.

Verified that data is still working after restoring my backup too. Calling / SMS seems completely busted though - calls get stuck at "dialing" and SMS messages just seem to disappear.
Any more advice would be appreciated

Help - Note 4 - SM-910G INU working only on 2g GSM.

UPDATE - 25/10/16 - Gave phone to Samsung Service center and they have updated me today that they found the radio is corrupted possibly so they have asked Samsung to give them a confirmation to proceed with Radio firmware reloading which includes IMEI re-coding. There's a chance of even them getting the device bricked of course but lets see what happens.
Hello all,
I have SM-N910G with latest stock rom (N910GDTS1DPI1).
Was using this phone on Reliance Jio VOLTE since end July and had set network more to LTE only (sicne RJio only has 4g LTE coverage).
Last thursday morning I noticed the phone is not registered on network and on trying to troubleshoot further by switching to a different (Vodafone) SIM, realized that the phone is only able to register on GSM (2G) networks and Edge data works too.
Have tried factory reset (and reloading of stock ROM thru ODIN including NAND erase using PIT files too) to check if I can get the phone to work on 3g/4g but no use. Seems like this is hardware issue (radio gone faulty?).
The phone is 18 months old so out of standard warranty hence I'm not much hopeful that Samsung Service center will be of any help. Before I take this there, just wanted to check if anyone else faced such issue before and have managed to sort the same out.
Cheers and thanks in advance.

Check your apn settings go to settings/mobile notworks and manually edit apn for you specific carrier.

Thanks but it's not an apn issue. The phone doesn't simply register on any 3g or 4g networks. Hence the thought that it's hardware issue.

same problem
Please if you get any solution do post here
As I am facing same problem but in my case
I am getting 3g & 2g signal & data also but not
Getting 4g volte to any sim I tried apn setting

What do you mean by not getting Volte on any SIM? It's only for Reliance Jio. For other service providers, you need to get a 4G SIM before you can use 4G.
My phone is now dead bricked and beyond repairs as confirmed by Samsung service center. I'm not spending 15k for motherboard change.

4g
I have idea 4g sim but when I insert it
My note 4 doesn't shows it it says no sim card
Insert sim when I put Jio sim I get no service/ Jio 4g
Emergency calls only signal when I tried bsnl 3g
& Tata Docomo 3g sims both sims getting network
Signal & I can call also but when I tried to connect to internet by using these 3g sims my mobile connects and switchs off suddenly I have to pull out battery or connect to charger to start the mobile
This is my problem

That's weird indeed. Have you ever tried any custom Roms or rooting because of which your Knox status would have tripped? In any case it's worth taking the phone to nearest samsung service center. They charge just 200 bucks to inspect the issue and another 200 to reload the software if needed. But in my case it was hardware fault so they couldn't do anything.

I haven't tried rooting yet and by the help of
A local mechanic who is a good friend of mine
And has a free entrance in local care center
We both went there and the care center gay
Tried to flash the mobile but no success now he says
That we should officially send the mobile to
The care center in a bigger city or like Mumbai
Where there are experts to tackle such weird problem

All the best mate. Just remember that they will ask you to sign up for Dead Brick risk which means you're OK if device goes dead during software flashing. The only way to get device working again is to replace motherboard which costs around 15k.
