[Q] How to edit ROM to re-enable APN Settings (ISW13HT - KDDI HTC J) - General Questions and Answers

I have a rooted ISW13HT (HTC J by KDDI in Japan) and I can switch to the HK radio for traveling overseas and unlocking the sim, however for mobile operators who require an APN, it doesn't work in the default ROM. For whatever reason, in the default version of the ROM (I'm still running 2.05.970.3) there is no option to edit the APN and it seems that KDDI has probably disabled it as it seems to be included in every other ROM version that I read about or tried. Currently when I travel I'm loading the HK ROM and using that since it has APN settings but this is far from ideal and I would like to just use my home ROM 100% of the time. I have to use the Japan ROM at home because of the Osaifu Keitai (Felica) function which seems not to work on other ROMs, or at least the Mobile Suica refuses to work on the HK ROM saying that the OS isn't supported and that is an essential function for me to use the train everyday.
I'm sure there has to be a way to edit the KDDI ROM to re-enable the APN Settings function, could someone lead me through this or point me in the right direction. I've tried searches and nothing turned up for me.

Wanted to bump this and see if anyone has come up with a solution yet. It's been quite a while since I asked before.

Virgin Mobile and Windows Mobile

I need the help of xda-developers!! I have a HTC Hermes and so far only one rom - I can't remember which, recognizes my Virgin (UK) sim as "Virgin" or "3G Virgin" - all the others I have tried see it as "T-Mobile UK" or similar. Is there anyway to fix this without things like Personalizer. I do not want to make the operator name fixed, I just want it to recognize it as it should.
EDIT: It was MrDSL ROM that recongized it as Virgin:
This one: http://forum.xda-developers.com/showthread.php?t=543842&highlight=mrdsl I tried the 3G version.

well what does not work when the rom sees your sim as "tmobile uk"
you can manually set the data settings if that is what is wrong.
Well nothing doesnt work - it's just that I want it to correctly recongize the sim. I realize that I have to set the data network manually, but I want it to say Virgin in the corner without me setting it that way with the Personlizer or the registry hack, because if I use that and go roaming I will need to disable it.
Whilst on the subject of Virgin Mobile, can one of the mods add Virgin as an option for the carriers on the User CP, I only chose T-Mobile cos Virgin uses their network here in the UK.
QuePPC UNLEASH ROM also works for me.

Problem with Skyrocket in india

Hi,
I have a galaxy skyrocket i727 from AT&T with last Gingerbread firmware(2.3.6 from at&t).Now i am in india.Recently i did a factory reset and now i have lost data connectivity(though i get full signal and can do calls or messages).
Even before i used to select frequency bands manually to swap between 2g-3g by dialling *#*#197328640#*#* and i used to get data fine.As there is no such option of selecting 'gsm only' or "wcdma preffered/gsm" in wireless&networks menu of the AT&T Firmware.
So the main question is if i put the unofficial ICS ROM like AOKP or UCALC4 than will i get this 2G to 3G selection in settings?Will the phone select indian frequency bands automatically?
thanks!
You may have lost your apn and that's why you can't get data, check under settings mobile network apn if there is anything there(I think that's how it goes in GB) if there isn't check your provider's site or call them and ask how you should configure it.
About your second question, it depends on what rom you will flash, some support it and some don't.

Thanks for replying!
My APN is ok.I requested new apn after deleting older ones and even did a manual "Add new apn" perfectly.Thats why i am asking this question ,because there is no reason for getting "no data".Everything is perfect except that there is no "E" or "H" symbol with up-down arrows beside the network strength bars!
Stupid question but did you enable data?

yeah dude!Obviously!
enabled - disabled it several times!rebooted after selecting apn etc etc But no good
Well sometimes we ignore the obvious so I had to ask. Check your apn again to be sure, make sure the internet apn and not mms apn is checked if you have 2, and it's defined as internet or internet+mms in case of one combined apn.
If this wont fix it something must have happened in the factory reset and you should try upgrading to ICS and see if it still works.
Hey.. BTW I have a question for you , how did you unlock your phone yo use it in India ? I know there are unlock codes, just curious if you got it from at&t or you had to go the eBay way ?

unlocked via z3x box....a tool used by unlockers.Had a friend of mine who owned it.It unlocks all samsungs for free!!
- You need to be SIM Unlocked and have a RAT Unlocked Radio (HINT: Roger I-727R radios)
and
- You need a ROM to support those, if you using TouchWiz I have supported this always from the beg. im my
ROM (see my sig.)
And I do travel there once a quarter, no issues for me. I have an IDEA Card and it works perfect, even ROAMING to 3G where IDEA piggy backs on other providers..

when i initially read your name ,i guessed you were indian!
Thanks for the reply.I just flashed the sk8erwitskil,s Latest Cyanogenmod 9 with UCLF6 libs just to check if i was able to switch radios,but right now i am in "2G/gsm only" area.Data is working fine,but cannot turn on wifi...it keeps saying "turning on".
My phone is sure sim-unlocked on idea network,and on UCLF6 Modem(is this thing same as a "radio"?).Initially i was on stock at&t GB firmware.Btw ,which place in india do u travel?
If wifi error persists i will flash EMBRYO Rom

ROMs for Global/GSM roaming

Hi everyone,
I have a d2vzw running Carbon ROM Kitkat. I spent the weekend back in the UK and enabled global mode, which connected to Vodafone's GSM/HSDPA network using the original Verizon SIM. So I had phone and SMS service - no problems at all.
However, I couldn't get a data connection. It was connected to the HSDPA network (enhanced 3G). Under Settings-->More...-->Mobile networks there is the option ("Access Point Names") to choose an APN. However, none showed up. I tried to add an APN manually, but as soon as I set Vodafone's MCC and MNC, it refused to save the APN info.
Oddly enough, the correct APN settings are all on the phone in Carbon ROMs "apns-conf.xml" file, they're just not showing up.
I tried everything to remedy this, but no luck.
So, here are two questions to harvest your collective wisdom:
First, is there a solution to this? I like Carbon ROM, but I have to have global data access for my work. If I can get my d2vzw running Carbon connected to international GSM networks and APN for internet, then I'd really like to.
Second, does anyone know of a KitKat ROM that DOES do this properly on the d2vzw?
Thank you so much,
M
I haven't checked in on AOSP ROMs in a while, but last time I did, none of them could do this, you need to run a Touchwiz-based ROM. AOSP ROMs like Carbon use a reverse-engineered radio interface which is not quite as good as the Samsung one which is included with TW ROMs, and this is one problem with it.
The bottom line is that if you want all the hardware features of your phone to work, you have to use a TW-based ROM, because Samsung hasn't opened up the hardware.

Thanks, Jacquestrapp. That's helpful. Perhaps I will flash a TW-based ROM and then keep it as a nandroid backup for when I go travelling.
I have been using my Verizon S3 in the Philippines as an international phone for months with excellent service. I am able to connect to the GSM network and transmit data at H+ speeds. I am on CM 10.1.3 official on Baseband MF1 and have been able to successfully switch to GSM using the PhoneInfo app. To assign proper APNs, I use the HiAPN app. Be very careful with Phone info: I once broke my connectivity messing with the settings too much ("Select radio band") and had to revert to Twiz and turn on the GSM bands using the "secret menu" to turn those back on. If you have a Twiz backup, try dialing *#2263# to choose the bands your phone has access to (seems impossible on other ROMs) if you keep having problems.
The thread here (see post 106) is enormously helpful.
The info about Twiz and reverse engineering is useful -- I haven't been able to get reliable service beyond CM 10.1.3 (very low signal, inability to send SMS, but somehow can receive SMS and voice calls), so I have been sticking to 10.1.3, unfortunately. I want to upgrade to 4.4, but haven't been able to do it without breaking GSM functionality. Has anyone gotten GSM and data to work on a 4.4 ROM?

[Q] Unlocking Mobile Data on Second Sim

Good day.
I currently have the Galaxy S6 dual sim version bought from a local network. It seems that although the second sim (whether in slot 1 or slot 2) can be used for SMS and calls, it CANNOT be used for mobile data.
I've tried flashing a supposedly OPEN LINE stock firmware (XTC brand, version 5.0.2) to try and open up both slots for mobile data, but although the phone firmware definitely updated, the second sim still is locked out from being used for mobile data. APN settings are locked for the second sim, again whether it was in slot 1 or slot 2.
Will flashing a different firmware (NOT FROM our country) work in unlocking the mobile data access? Will I have issues if the CSC comes from another country while I use this phone here at home?
Thanks!
Help with build.prop settings
So I've tried rooting and going around the build.prop file. I've tried to install a couple of lines that seemed to open up the APN settings of other network-locked phones:
ril.sales_code=LOL
ro.csc.sales_code=LOL
However, I'm only still able to add or modify APN settings for the sim of the network but not for a sim for another network. Maybe there's a modification to the build.prop file that can be done to finally open up APN settings for both sims?
UP
Still hoping someone can help me with this, either with a firmware for the dual sim version that can unlock the data/APN settings for any sim in both slots or possibly some build.prop tweak settings that can do the same.
SOLVED
Was able to find a tech guy who downloaded a program that "debranded/unbranded" the unit, making it a plain vanilla S6 Duos. Now any sim can work with data in any slot, APN settings activated.
link to the program please
Hello, I'm having the same problem, could you advise what was done to make your apn setting enabled?
Yes, link to the program will be very useful to all of us.

[Completed] Help! Tmobile Samsung S7 locked only on 1800 mhz band. Already rooted

Hi everyone.
Last time i was in xda forums was when i try to mod my windows mobile CE 5.0 lol
This is my sad story:
I bought in the US a samsung s7 with T-Mobile SM-G930T, i paid a guy who 'unlocked' it in there. After that i brought it to Colombia, in here i run the T-mobile unlock app which succeded and erased itself after that. Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys

Hi,
It seems your phone is region locked due to which you are locked onto a particular mhz network frequency...
yes the first step would be to try to a custom rom to see if this over rides this situation or you could try below situation below... this is ideally for s6.... or atlast google search...
http://forum.xda-developers.com/verizon-galaxy-s6/general/enabling-using-servicemode-t3109579
Ok, since now we have root, many users wanted to know if they can lock onto certain LTE frequency bands using Samsung's ServiceMode. So here is a quick guide.
ServiceMode is Samsung's proprietary Engineering Mode, built within the TouchWiz framework, readily available on International variants, and some domestic like T-Mobile. It allows us to observe the RF connection, change certain RF related settings, and lock our phones onto specific technologies and frequencies. Sadly, Verizon has been blocking user access to Engineering Mode for years now.
So in order to enable access to ServiceMode on Verizon GS6/Edge you'll need to:
- Download Root Explorer
- Navigate to /efs/carrier/HiddenMenu
- Use TextEdit to open it (not text viewer)
- Change the value to ON (upper case), Save and Exit
- Restart the phone
Once restarted you can dial:
*#0011# to observe the connection
If you want to lock your device onto a specific LTE band (13, 4, 2):
*#27663368378#
- UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
- LTE Band Selection
Here you can force your phone onto a specific Verizon LTE Band (13, 4, 2), or use LTE ALL if you have VoLTE (Advanced Calling) enabled as this will eliminate the need for CDMA radios.
To go back to default, go through the same process but at Band Selection make sure to chose AUTOMATIC.
There are a lot more settings here, you can enable AMR WB on UMTS if you use T-Mobile so you can get HD Voice on their UMTS layer, etc... Carrier Aggregation has already been enabled, so no need to tweak that.
If you aren't sure what certain settings and values correspond to, it's better to avoid tinkering. You're responsible for your own actions.
According to this thread, he posted via visitor.
Then he registered and posted his query here so he seems to have posted in correct section.
Just documenting this here.
