No Signal problem

So, my Xperia Z has "no signal" error when i put my micro SIM card into its slot. Interesting is that when i turn the phone on it asks for a PIN, when i put the correct PIN in and confirm it has no signal at all... in the menu also appear "O2 Sim" apk after few seconds and my phone can even import contacts from SIM :laugh: ... well i am out of ideas.
Things i have tried:
Reinstall Android 4.4 via PC Companion
Downgrade to 4.3 via Flashtool
Downgrade to 4.2.2 via Flashtool
Reboot many times
Took SIM in and out many times + tried SIM in my second phone (XS) it worked normally...
I also tried SIM from different provider - same problem
Changed GSM to WCDMA only, ... (all options)
Add AP point
Find provider Auto/Manually - no service found
Checked if my phone is showing it's IMEI - yes it is
Checked if my phone isn't locked - no its unlocked
My phone is now BT locked, running Android 4.4 (10.5.A.0.230) non-rooted, at first i was thinking its a HW problem but well could it be if it recognizes the SIM card?
Last thing i am thinking about is to change my SIM to USIM, but i am not sure if it will help...
*Edit* I forgot to say everything execpt Network service (calls, sms, data) is working fine. *Edit*
*Edit2* After searching all over the google it seems like i am not alone... i have the same issue like this user https://www.youtube.com/watch?v=WdJ0DREwdEM " *Edit2*
*Edit3* I am adding some screenshots *Edit3*

Not working, check the video i posted before, phone can't find any service provider and i am not able to switch to manual... its reallly strange, i am trying to find some fix or something for about 4 hours + searching google, xda, youtube, ... and what i found? A lot of people with the same issue but no fix ...

After another X hours of looking for issue i found the reason - Antenna Board is probably faulty, i have found the same issue at some iPhone forum when the user had no signal (same as me) and fixed it by changing this little board located at the bottom of phone. But anyway if you know it won't help let me know I will post a reply when new AB will arrive and if change helped.

I don't think there is any issue with the base band

Well i can't go to service center because i lost my warranty... any other solution how to fix it? btw where has Xperia Z located Antenna for GSM ? If it is HW issue like damaged Antenna i can fix it with buying new one but i really need someone to tell me which part of the phone can make this issue to buy the correct new part not whole new phone ...

Does not mean that the antenna is broken, can be a loose contact also
You are getting the pin prompt because the sim reader is working properly
it is unable to register to network because of antenna issue, better you show it at a mobile shop than doing self diagnosis

[Q] No data roaming option

Hi,
I bought a gsm unlocked sprint htc m8 from a 3rd party vendor recently. (It was only after the purchase that i realised it was a sprint phone). The phone worked pretty well on my network until i moved to a different city. The trouble is that data doesn't work here for some reason and there is no data roaming option on the device.
The vendor has agreed to sort it out but it will be quite a while before I go back and give him the device. So i wish to try something on my own.
My research on here has yielded that I probably need to change a few settings in the default.xml under system/customize/ACC. Or there could a better way of enabling it.
So far, all the steps I need to take seem disjointed and therefore I'd like someone to please guide me through a step by step process on how to enable the data roaming option. I'm sure I'd be able to follow the instructions as I've previously installed a custom rom on my HTC One S.
The phone is not rooted, although it says "tampered" when i enter the hboot menu. In the same menu it also says "unlocked"
Let me know if you want any further information

for Sprint users, the roaming appears after being activated/provisioned...you can try changing "sku_id" to 42 in system/customize/ACC/default.xml (it's near the bottom)....but u will need root to change that file. If you have TWRP recovery, it should prompt u (when rebooting to OS) to install root if it's not detected

Thanks!!! Much appreciated. So once i'm rooted, do I need some tool to pull the file off the phone or can i simply edit it on the device itself?
Yes I have TWRP, will it auto-root my device when i get the root prompt?
Also I read somewhere, under the default.xml these entries need to be changed to "true" or will changing the sku_id suffice?
<app name="Android_Ril">
<item type="boolean" name="allow_national_roaming">true</item>
<app name="Phone">

The alternate method is for those who have the roaming options but are greyed out. In my case there is no option roaming option at all, may be because the phone is unactivated. Anyway I'll try the previous steps over the weekend and post results

Hey, so I installed Viper m8 rom, data now works in roaming but it catches only EDGE. 3g is not working. Any clues on how to make that work?

Hi,
I bought a GSM HTC One M8 from a third party vendor in India.
I don't get data roaming options in my phone. I have flashed it using Bad_Boyz_Sprint_ONE_M8_Harman_v1.5
Changed SKU_ID to 42. Updated data and voice roaming guards to Allowed as well. Still no success.
Can anyone help me out?
Please let me know if more information is required.
Thanks

This did it for me

You need to be S-off
Try the following on you responsibility
- You should know your SPC, you can read it with CDMA Workshop or CDMA DFS Tool.
- Install QSPT (http://forum.xda-developers.com/show....php?t=2263391)
- enable diag mode ##3424#
- open QPST configuration, from port tab add your device diagnostics port.
- from start clients tab choose service programming then ok & click on read from phone.
- on system tab choose automatic for roam preferences.
- on UMTS System tab choose any for pref service domain & any band (last bottom right) for proffered band.
- click write to phone, then your device should work on GSM mode with modified HTCOMADM_SPCS.apk.

Wolf,
About the Ativ S with region CSC ZTO
I did all the things we talked about. following the entire procedure you sent to me, but the result was not so good.
After hard resets, my carrier continues broadcasting me a message in every reception signal change (and turning off the broadcast messages in settings don't resolve this issue).
I follow these steps:
1) downgrade to GDR3 (I8750OXACMJ1 + original CSC with ATO)
2) hard reset
3) install all updates via ota (including wp8.1.1 + sammy update + new bootloader)
4) hard reset
5) MBN Creator to change region with the file you sent (evrything was ok, all 5 "Dones" appear)
6) reboot
7) hard reset
8) in Diagnosis (*#1234#) the ZTO was there (system adjust CSC version to I8750ZTODNI3)
9) everything was going fine, system downloaded my portuguese language package for keyboard and speech
10) engines to install language support .......... and.........
11) ANNOOOOOYIIIIING BROADCAST MESSAGES!!!! (((
So, now I downgrade again to GDR3, but this time with my original region CSC ZTO.
Everything is great. Carrier broadcasting was gone, but no updates for me.
Thats it. I'm waiting for a solution, because official wp8.1.1 is awesome,
Ativ S worked better than ever for me on it.
Wolf,
thank you A LOT for supporting me, I hope you find the "missing line" that cause that region carrier issue n the new MBN Creator.. I'm sure many people will benefit from the solution.

There is an option in "advanced text messages" settings. May be it's selected.
You original CSC version (that you flashed) was I8750ZTOALL3. So, it was updated somehow. May be Samsung did something wrong once more.

I tried this like i said in the reply. No changes at all.
And that thing only happens with differents CSCs than the original ZTO here in Brazil.
I read in some place, I can't remember, some guys from London, when travelling and using local SIM carriers, had the same problem.
My question is: why when i aplly the CSC ZTO directly in rom flashing the things work fine..... but when i flash only the CSC in wp8.1.1 it turns my region into a mess?
Misteries..............

Some curious..
I noticed something when I tryed the rom I8750OXAALL3 (GDR1) + original ATO CSC.
In Diagnosis info versions (*#1234#) appears in fields PDA, Phone and CSC >>> last 4 characters ALL3.
Then the system updated "Over The Air" to GDR2, and the last 4 characters changed to BME1.
Same happened after GDR3 update. Last 4 characters changed to CMJ1 ...
and finally after the wp8.1.1, last 4 characters changed to DNI3.
In all these times, keeping the rest intact, I8750OXA----.
And conferring with the available ROMS out there, the names match.
So, i guess the last 4 characters indicate the system version, GDR 1,2,3, 8.1.1 ..
When I did those tries with your file MBN to my ZTO in WP8.1.1, before hard reseting the diagnosis didn't open, and I couldn't view the version that it showed to the CSC.
After hard reseting, my CSC was I8750ZTODNI3
Now I'm using GDR3 flashed with my original I8750ZTOALL3.csc file, and in diagnosis the version shown in CSC field is I8750ZTOCMJ1. >>>AFTER HARD RESET!
Before hard reset, it showed I8750ZTOALL3.
Crazy. But its working fine.
I think when this rom I8750OXADNI3 (official 8.1.1) appear, it will save a lot of people in same situation as I. With all these flashes that I've done in the last few days, the best choice always was flashing a ROM togheter the original CSC ZTO.

Ativ SE
Will the MBN Creator work with an Ative SE, If so is there anything that needs to be altered?
Can a Custom Rom be made for the Ativ SE like the older models?

Changing some registry entries
Hey everyone, I have an Ativ S Neo with the option to enable voice roaming greyed out. Someone found a fix by changing these four keys from 1 to 0:
[HKLM\Software\Microsoft\Connectivity\CellUXOEMConfigurable\]
"HideDataRoamingInternational=0"
"HideDataRoamingDomestic=0"
"HideVoiceRoamingInternational=0"
"HideVoiceRoamingDomestic=0"
People have been using this fix by interop unlocking the phone and using the registry editor, but I thought maybe this tool would be easier. Could someone help me out? I generated an MBN using the tool and added exactly what appears above to the registry. I don't want any other tweaks. So my questions are 1) did I format the above correctly? 2) If so, how do I use the MBN generated to actually make the change on the phone? I've flashed my phone back to stock before using the flash kit, but I've never flashed anything custom. Do I use the .wp8 file that came with the flash kit, and the MBN instead of the CSC? That would be easy!
Maybe I would be better off just interop unlocking using the other guide (http://forum.xda-developers.com/showthread.php?t=2435697) but I wasn't sure if that still works, plus it seems harder.
Thanks for your help!

To put it differently, and perhaps better, will adding those four keys above change the existing values from 1 to 0? Will it overwrite? Thanks,

This seems great, really appreciate the effort wolf. Going to play around with this soon.

How to change model name?
I've looked at the MBN Creator tool and it isn't obvious how to change a phone's model name from there. Your OP said it was possible to change the phone model (model name?) on a Neo; how does one do so?
I'm migrating from one carrier to another and I have the new carrier's signed CSC and WP8 images. Each carrier uses a different model name for the same phone, and looking at the raw files it does seem all of these phones share the same code base.
Even so, the WP8 downloader tools (up to 5.3 anyway) will not send a mismatched model number image up to a phone, and there didn't seem to be a way to override that.
And a Thanks already for the MBN Creator tool.

MBN Creator changes phone model of the ROM, not phone. You can use any tweak tool to change phone model like it's done for update to WP10.

Hmmm wait.
I have Samsung Ativ S with 8.10.14157.200. Can I use this hack to do interop unlock? I can't unlock it GDR2 way because diagnosis app is lacking regedit now.
Also sorry but You didnt gave any instructions how this tool works. Do I need to have WP8 rom and then generate MBN? Or can I just generate MBN and flash it to my current ROM? Do device need to be in download mode? Do I need to match CSC with current ROM?
So many questions, sorry.I would like to be sure that im doing it the good way.

No signal after *#*#4636#*#* PS. Don't change anything on it!!!!

Hello guys.
I have a Z3+ dual and searching on net i found a ussd code that give the possibilty to change the SIM card technology. I perfom some change on it including choose the 'USA BAND'..... Yep, i'm a asshole......
After that my first sim loose the signal. The triangle gets blank... I just have signal on chip 1 when i put WCDMA on it, but this force my second chip to gsm and consequently i loose the signal from second chip.
After alot of tries i could bring back the signal for both chips: I put the WCDMA only on sim card 1 on the 'mobile network'. After that i went to the *#*#4636#*#* menu and put the LTE/WCDMA Pref. and i made a restart. When the phone started i go to the 'mobile network' and put the second chip to LTE. Bingo... Both chips starts to work together....
But not everthing works fine.... When i restarted my phone again i loose my signal from first chip again i need to perform everthing to get everything works...
So, for now i need a help to solve this once for all. Maybe a way to reset the values to default.... Some site tell that we can put something on build. prop.
The best setup is works 3g on first chip and 3g/4g on the second at same time.
Positively don't change anything on this menu.

Try changing Modem file. It worked for me. Finnd that HERE, do not replace files and follow the rest of directions. Change to any modem file and change it back to your default selected one.

SOLVED: Full mobile 4G+ data signal, but no data comes through

Hi everyone
I have a strange problem. I bought the "International" version, which was of course the Tencent with a flashed ROM. Although it was sold as "International" hehe
I didn't have Google Pay working and I've flashed the 1703 together with fingerprint, re-locked it down after and then updated with the latest firmware from the Asus website. (Google Pay works now)
Version WW-16.0631.1908.21
I now see that even though I have a FULL 4G+ signal. Calls come through normally etc. but the internet on mobile data simply doesn't work.
Anybody have any advice what else I could do?
EDIT:
It was a simple APN problem

There are no topics on how to get OTA, i googled, all topics say its Impossible.
I want to know how he used offical update to update the phone, i just updated using one of the updates here in FASTBOOT mode.
If you know about topic that can enable REAL OTA that works or if you at least know how i can use ASUS offical updates to update [ mean i assume you just copy the zip file to the USB and it auto updates?]
Do tell me

Idk how to turn on real OTA thing, but if u want update to official ROM (copy zip file to internal storage), make sure your fingerprint set to same with your ROM (ex: WW ROM with WW Fingerprint), that works with me

I just googled what my mobile phone carrier APN was and entered it instead of the wrong one.
You can find the one in the phone by simply going to settings > network and internet > mobile network -> APN ( Access Point Names )

I just started having this issue yesterday! Phone has been working great for over a month then all of a sudden 4g shows it's on and connected but no mobile data coming through! My APN is correct, and I'm using Straight Talk through the TMobile network... Still haven't been able to fix it.

Same issue here internet connection dropping

I wonder if T-Mobile is doing some "dry runs" before they officially light up their 5G network on December 6th. (src: https://www.t-mobile.com/coverage/4...d=WMM_TMO_P_19NETWRK5G_91WOGGGY1WERV94JC18747)

I am having same issue. Adding APN works for few hours. Then drops out. What to do? Did you guys find any solution?

Assalam alaykum
I suffered from dropping internet dropping connection
The solution was APN
Go to settings > network and internet > mobile network -> APN ( Access Point Names )
click the ( Access Point Names ) and you will find many APN setting Depend on your internet provider
Click one of them and then and on far top right option button click (delete APN)
Repeat this until you delete them all
Click the ( + ) sign to create new APN
Now go to thia site:
https://www.apnsettings.org/
And search for your country or internet provider
Copy the APN setting from the website to you your phone
Then save.
Hope it could help you
In case you couldn't connect to the internet at all
you can always restore your previous setting by :
Go to settings > network and internet > mobile network -> APN ( Access Point Names )
on far top right option button click (reset to default)
