[Q] Can I install a stock Samsung rom on my O2 (network) Samsung Ace?

Hi all. Please excuse me if this has been asked before, this forum is daunting for me and it's hard to find the required info I need. Basically, my brother forwarded me to a thread which explains the process of rooting my phone and installing a custom rom. That thread still exists and that's fine so I know where to look on how to root and install a rom.
My question though is about the installation of a Samsung factory rom. I bought my phone through a network provider, O2 Ireland, and as such, it comes preinstalled with some O2 apps that I don't use or need as well as a O2 boot screen. I would like to setup my phone to work as if it came out of the Samsung factory without any network provider rom so can I install a Samsung factory rom over my O2-based rom or will it brick my phone? Also, I know that the place to go to get roms is samfirmware.com but the roms I found there have a carrier associated with them. The roms I found were either for Ireland, eMobile or Meteor and for UK, Orange. I want a stock Samsung rom so anyone know where I can get this?
Thank you for your time and I apologise again if this has been asked before.

I think it's de official rom without carrier's modification, so yes you can flash it via Odin but first of all are you device unlocked? and Have you got the S5830 model? It's very important!

Thanks . I was planning on installing the stock rom through CWM Recovery after rooting my phone first ofcourse so is this ok or is it a must that I do it through Odin? Yes, I unlocked my phone so it works with any network now. Yep, I have the S5830 model.

[Q] Help needed, stuck after updating firmware (emergency call)

Hi,
Well my device which is S5 mini g800f working fine, since I have changed the firmware which was old like build on july so I tried to installed latest, but now there is emergency call showing, also I have tried manually and automatically to register on the network but it says unable to register to the (---network). I did it coz my device was not showing LTE network. However my sim supports the 4g and was working on S4 i9505. I have searched on Google and look out many threads on XDA but no success until now.
The biggest mistake was I didn't looked the firmware which was already there and was running with 3g support. I have tried these EUR-G800FXXU1ANL1-20141226162921, SER-G800FXXU1ANG1-20140709112536, MAT-G800FXXU1ANI3-20141218172328. Then I have installed Custom Lollipop but no success was there too.
So now any pro's here who can understand my problem ? My imei is showing, is there any procedure where I can put the imei and it will let me know what was installed on stock :crying:
Sorry for being noobish..

Please any buddy give me suggestions that what should I do ? Or should I look in the specific section of XDA forums ?

What do you mean by this? IMEI showing or Not?

Its is mentioned mate what I have written, I said my imei is showing that by dialing *#06# I can see it, because there is a problem where the efs folder corrupted or gone you cant see imei or imei appears to be in these digits 00000 especially by installing custom roms. Anyways my only motive is that I know the imei and how ever I can see it too, so is there any procedure where I can put the imei to the website and see what was installed on stock. Because I dont have the box so I dont know which firmware was there when I installed another rom to get LTE, because it was working properly as I said in my earlier post.
Problem is due the baseband I am pretty sure which is not matching, this is the reason because I cant connect to the network---error msg (Unable to connect).

The baseband firmware is included in the firmware packages that are available on sammobile (.tar.md5 files). If you flash the firmware package with Odin, also the baseband firmware (contained in modem.bin) will be flashed.
If you have problems with a newly flashed stock firmware that were not present with the original firmware it might be because of one of the following reasons:
You flashed the wrong firmware. I don't think that the version name of the original firmware is stored somewhere. Instead check sammobile for the correct one: select the correct phone model and your country. EUR, SER (for Russia), MAT are country codes, choose the correct one for your country, the search function on sammobile will help you with that. You can also try Kies for restoring the firmware. Maybe that is able to determine the correct firmware according to the IMEI or some other information stored on the phone.
Maybe your EFS partition was changed and corrupted. The EFS partition is the partition that contains the IMEI and other information like calibration files that are specific for your device. If any of the files in this partition is damaged, the phone might not behave correctly. If you flash another firmware the EFS partition normally is not changed.
Your hardware is defect.
I guess that you simply flashed the wrong ROM. Otherwise the problem will be hard to fix.

Help!

Hello guys!
Six months ago I bought a used note 8 SM N950F once I tried to install another rom (custom one) after backing up the whole mobile by twrp, after installing the rom, the phone couldn't detect sim cards and imei, when I returned to the backed up rom everything were fine.
I searched for my phone's imei and the result was these imei numbers belong to another samsung device, samsung ace I think.
What is the problem? I can't use any rom exept the original stock rom which already installed to this device, help me finding a solution to install another roms with working sim cards.

Which ROM u tried? And also did u make a backup of efs?

Could I make an EFS back up and use this back up for the other rom?

Yes i think it can be done
... Quite a few tutorials to do that online. Go ahead and Google it.... I have not done it myself. So i will not be held responsible if anything goes wrong. But it should work. All the best.

Emergency Calls Only on Custom ROM N950F/N/FD - URGENT HELP

I am new to Android Custom ROM and everything. I got this phone from a local vendor and it was running a custom rom called "LamLazy Rom v3.0 Dual SIM" - I researched on it and figured it was used to convert N950N to N950F or something like that.
I have the EFS and TWRP complete backup of the LamLazy ROM. I wanted to try LineageOS 17.1 on my device and flashed it using TWRP. After the successful flashing, I noticed my phone can no longer connect with my network. I cannot make or receive phone calls. I tried every possible thing that I knew. Even flashed series of Custom ROMs, on every other rom I faced the same network issue.
However, when I revert back to LamLazy it works fine. I can use both of my SIM slots and my phone shows 2 IMEI's while on lineage and other it shows only one IMEI.
Now, my problem is I want to get rid of LamLazy and try new ROMs such as Pixel Experience and LineageOS, but my cellular network doesn't work. Can someone please help me with this? :crying:
