[Q] Help with updating omega rom / going back to stock rom - General Questions and Answers

Hi, I am new to this forum and I have been searching around to find out the answer for my problem but I couldn't :crying:
I have few questions/issues.
I have Galaxy S3 (GT-9300). I have brought in it New Zealand but it was unlocked phone. So when I did was installing the omega rom, I found out that the rom it had was the rom from one of the europe countries (I can't remember)
I was wondering if I can install any GT-9300 stock rom to get back to stock rom phone or do I somehow have to find out which stock rom it had before?
The other question is that I was trying to reinstall and update the omega rom from the scratch by going to stock rom then installing the latest omega rom. But my phone somehow won't connect to the PC, it charges properly and I know computer or cable 's problem. I have searched and searched on google but couldn't find any solution to resolve that. (Tried different versions of Kies, tried removing everything turning off the phone and restarting)
Because of that, I can't use Odin to change Roms or anything. Is there anything I can do to resolve this problem or changing Roms without connecting to the computer?
Currently, I have Omega v54.
Thanks so much

[Q] Wifi issue

Hi, I have vodafone 858 which I rooted with z4root installed cwm and flashed a custom rom. I have flashed a couple more different roms since then but now I seem to have an issue with the wifi on it, as I can find networks but the phone refuses to connect to them even right next to the router. I tried flashing different roms and re installing recovery via rom manager but the problem stays the same!!! wifi only works if I restore back to the gingerbread G360 rom I had on it. please help!! thanks!!

[Q] Galaxy s2, After I install custom ROM, wifi and radio do not turn on

Fairly new to alot of this...please forgive me. I have scoured forums and cannot find an answer to my problem. I got a new S2 about a month ago and I rooted it no prob. When I tried to install CYM 10 (stable and nightlys) It installed but the wifi and radio are shut off. Found a rooted stock and was using it as it was better than what I had stock on the phone but not being able to do it bothered me. After many posts regarding some of these issues with other phones, I have: Updated my prl and anything else I could update successfully, tried again and same problem. I tried turning on, up, down, and everything else I could do with the settings having no wifi or data and went back to the rooted stock. I flashed a radio update sucessfully and then tried messing with Kernals. Dragonics ROM comes with a new kernal flash among many other things and I tried that, installed sucessfully but still not wifi or radio....I even tried flashing older roms and kernals and still nothing.
As of right now I am back to the rooted stock running stupid themes to make me feel like I did something. I cannot find a direct answer to this regarding my model and that I have not tried. This has become an obsession...I HAVE to make this work. Please Help me.
Again, fairly new here and to forums in general and sorry if I did any of this wrong...

[Q] 3g no longer working on my phone after flashing roms SCH-I500

So, after hours of looking for the stock rom for my Samsung galaxy S ( I don't know which one it is.. It just says samsung at the top and bottom) I found a gingerbread rom, and I flashed it to my phone via Odin. I reset the phone, and I no longer had my 3g, and my phone number says "Unknown". I installed Froyo 2.2.2 before this, and it was working perfectly, except that wasn't the stock that I was looking for, and so that was the reason I flashed the gingerbread ROM.. If anyone could help me, it'd be a big help.

aww Cmon.. :crying:
No one?
Probably something went wrong with the modem flash. The stock rom contained the modem for the rom itself? It happened to me on a galaxy ace. I flashed a 4.0.4 rom and then i lost the signal (only 3g/2g, not the wifi). Then I flashed a custom rom based on the original one and now everything works. Try to search the official rom for your device on sammobile.
:/
Well, I've spent days looking for the stock ROM :/ I couldn't find the one for mine..
You said install a custom ROM? won't that require a ROOT?
I can't find my model, "SCH-I500" on sammobile.

			
				
Ok, I installed http://www.mediafire.com/download/c7h1wl5wne51duf/ed05_radio.tar.md5.. so I'm able to send/recieve calls, but I still don't see "3g network" icon on the top of my phone, meaning that I don't have 3g..
anyone??
...
Rage..
Eh..
guys... Help me.

[Resolved] [Q] Impossible to instal Android Revolution

Hello.
First of all, I tried searching for a similar problem but I haven't found anything quite like this.
I have a SG S3 with a stock 4.3 Rom (but I was on cyanogenmod 11 before that).
And I wanted to try Android Revolution (ARHD), so I added CWM and downloaded ARHD 51.0 from here. I then proceed to install it via the SD card in recovery mode (after wipe) like it's recommended. The installation goes on, the phone restarts. And I'm back to my stock rom (rooted mind you), like I did not even try installing ARHD.
My current version is I9300XXUGNA8, I guess I should be on I9300XXUGNB6 after install, but there's absolutely no change whatsoever. I tried this 3-4 times with always the same results.
Has anyone ever had this problem? Do you know why I can't seem to install this ROM?
Many thanks in advance for any help on this!

Galaxy S6- Wifi Fail After Custom Rom Install

S6 Wifi Fail after Custom Rom Install
Hi guys,
I've just recently (over the weekend) installed VaderRom on my S6, but after I installed the custom ROM (not after root/kernel flash, which was a few days before) I can no longer use WiFi. The phone connects to the Wifi – not problems there, the connection is "Very Good" – but it absolutely refuses to transmit any data over the network. Every internet based app says I'm not connected to the net.
I have a G920I, which I had already updated to stock 5.1.1; Flashed the unikernel appropriate to my model (no issues), got Root, custom recovery, etc. Then, later, I decided to install VaderRom – no issues with install, and everything worked fine. Except WiFi.
Tried XtreStroLite as well, just to see if anything changed, but no joy.
Tried flashing a new bootloader and modem (currently this one: http://forum.xda-developers.com/galaxy-s6/development/guide-920i-modem-xtrestolite-support-t3154861), but no change.
Have now restored to a nandroid backup from before the custom ROM flash, but I still can't get any data over Wifi.
Soooooo............ Does anyone have any ideas? I've Googled, I've searched these forums, I've looked for the last few days for a solution, but I've not seen a single post that seems to cover this issue.
Cheers for any help!
[edit]
So I flashed the appropriate firmware from samsung-firmware.org, which has fixed my WiFi problem. So, problem fixed, but not solved. If anyone has an idea of why this happened, and how I would install a custom rom and prevent this from reoccurring, I'd be much obliged.
