will flashing an unlocked device with another rom be causinng a problem ? - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

hey i got my note 4 (N910P) from Texas and brought it to my home country India so i just read the message but i wanted to confirm that if i flash my sprint note 4 (N910P) with a different country rom or any other rom then will it be causing any problem ? i have unlocked it but i am now facing the issues with the carrier featured applications so it is unlocked and ya of course i will keep the model no. in mind for finding the rom then it will be good to go right if i flash it with the same model no. the country doesn't matter ? also tell me how can i become sure of that it is unlocked
TIA dude

You should probably ask this in the Note 4 forum of XDA...
And no, the country doesn't usually matter as long as you are using a ROM that wasn't edited by a carrier (a lot of ROMs on sammobile, for example).

Well, one simple way is get another active SIM card, insert it and try to call someone. If it works, it's unlocked. If there's an error, it's still carrier-locked. Other option is installing GalaxSim Unlock, and open it - if it offers to unlock your phone, it's still locked, but if it says anything like "lock is not present" or "SIM Lock Status: undefined", it's unlocked.

[Q] Region locked Note 3 - can i flash Poland 4.4.2 update?

If i have Orange (UK carrier) region locked Note 3 model: SM-N9005, can i flash Poland update [N9005XXUENA6]?
http://www.sammobile.com/firmwares/3/?download=24151
I saw many people around the EU are flashing this but does carrier - region locked function have an influence here?
I understand region locked is only about preventing other SIM cards to be inserted and there should not be a problem but you know, i would like to know for sure. Is any one here who has done that and can confirm it works?
Thanx
Your region lock will gi away if you do 5mins of calla in your hime country.
Then flash the kitkat

It might be very relevant if you are carrier-locked (in which case I strongly advise against) or just region-locked - and even if you are not carrier-locked I would not suggest JUST YET to jump on N9005XXUENA6 Polish (XEO) version - the thing is that your current CSC might be something that is not supported by the multi-CSC in the XEO version and things might not always go well in such conditions. That is why I am a little concerned about going to the XEO version myself - even if now there is a confirmed way to keep root and knox 0x0.

I have an Unlocked and Rooted SM-N9005 from Europe (XXUBMJ), but I can't use it in Canada, and it says, Not registered on network. is there anyway that I can change my firmware or install a new ROM or a new Modem so I can use the phone with Canadian sim card???

It'll be region locked if it's a European model by the sounds of it, try region lock away and see if that works, failing that, a Custom ROM usually fixes it also.
So its posssible for me to install Custom Roms e.g. Omega Rom on a Pink Note 3 that was already unlocked? I'm using an Asian SIM and when I bought the pink note 3 for my wife, the phone was for EU SIM. I checked the phone status on download mode, knox has been tripped, binary status to modified/custom etc etc. Looks like the phone was rooted to have region lock away installed and then unrooted. Planning on install Omega Rom but wanted to make sure the phone will still read the Asian SIM.

Check with the custom ROM OP if it has the CSC (sim region) you require

I've already did that. I installed region lock away, and region unlocked it. What custom ROM do you think I have to install? Do you have any trusted source so I can get a custom ROM from them?
Check the Android dev section, there's a few decent ROMs in there. - I have pretty much used them all on 4.3 and tried all now on 4.4
EDIT: X-Note is regionfree as is Omega, both are very popular, however SweetROM and AndroidNOW now can certainly hold their own and are just as good (also region free)

[Q] G900F Network registration problem after flashing

Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.

Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:

with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch

[Q] N9005 "Not registered on network" after regional unlock. PLEASE HELP!

Good day, I have N9005 from UK but Iam from Middle East.
Because code for regional unlock doesn't work for me I gave my phone to the phone lab where they just changed my IMEI. After that everything was fine, until I decided to flash another rom (Knox already 0x1,so its doesn't matter).
Because I want new Modem I flashed first last Finland 4.4.2 and after that custom rom and changed cellular operator and sim card.
Now I see "Not registered on network" on Note 3 when on my N7100 this sim works perfect.
In Download Mod I have this info (attached).
What I should do now? I tried to find info about it, but nothing.
Thanks in advance for any help.

Flashing an unbranded firmware on a carrier-locked phone ??

So I was wondering if this is possible. My phone (A510F running lollipop 5.1.1) is locked to a carrier but I was planing on flashing an unbranded 6.0.1 (from Italy). Marshmallow will eventually come to my country but I just can`t wait anymore. Will flashing this firmware brick anything ?? I am well aware that the phone will remain locked to my carrier, since the lock has to do with the phone`s imei number, but is anything else going to be affected ? Anyone had a similar experience ? Your answers are really appreciated.
Bad idea, never flash unbranded firmware on a locked phone as it leads to all sorts of problems. Get turn phone unlocked first and then u can flash any firmware.

why would you ask Note 4 questions in A Series threads when the Note 4 threads are at least 10x more active? Besides, no one will know the answer here anyway.
