Antenna issues after swapping motherboards - Galaxy S III Q&A, Help & Troubleshooting

Hey all! I swapped the motherboard of a i9305 to a i9300 since they are identical in almost every way and needed a new screen. However now when I turn it on it has zero or one bars where it once had full bars in the same location.
If anyone has any suggestions they would be very much appreciated. PS I already tried replacing the signal cable/ antenna from the i9305.
Thanks!

Maybe u can try flashing another modem.

Cut the bickering about which section it belongs to... why even post it in the first place? Just report it if you don't think its in the right section.
Settling this matter once and for all... the OP is asking for suggestions - note the word asking. To ask for anything is to ask a question, therefore no matter how its phrased, its a question and so belongs in the Q&A section.
Thread cleaned and moved.

[Q] Samsung Galaxy S2 Help!

Hey people I come to you with a question, not so much about the SGS2 but I am stuggling and I am an owner and Don't know where else to go.
My question is Ports and Connectors (general Computer hardware)
are they the same? what is the difference etc if they are different?
I am sorry to ask this here but you are the smartest people I know and I could not find the answers on our good friend Google.
thanks
Depends on what ports and connectors you're talking about. What are you trying to accomplish?

[Q] Split forums for development?

Hi SGS2 peeps,
First off I'm a epic 4g user, my girl friend bought SGS2 i9100 so I headed to XDA right away.
Looked under SGS2 i9100 there are 2 developments?? Thats confusing I had to read through http://forum.xda-developers.com/showthread.php?t=1175660 to understand what exactly the issue is,
Anyways to voice my opinion I DON'T support split at all.
Reason: As a mere new user I don't want to look in two places and decide what to do more than anything else it is confusing.
If any developer so want to then they can easily create their own web portal for e.g. ACSyndicate over at EPIC 4G, they have probably the best ROMs for epic and have their own website, however they still actively post new development over here at XDA as well.
Anyways thats just my view, I don't think it matters to mods. So the question is: Which ROM currently users are favoring? and is there any separate forum (other than XDA) for SGS2 to follow ?
I dont support the same question or topic posted multiple times .
Nor do i support questions posted in the wrong forum .
jje
Even I don't like duplicate questions but if above mentioned thread was not closed I would have replied to that only.
Well in any case if this thread is so much bothering, moderators can delete / move it, I'm pretty sure they can do this much after going all the way to split the forum.

[Q] I9300 motherboard replace

Hi, i'm from dominican republic, my S3 GT-I9300 died because of "SDS", but it didn't have warranty so Samsung won't change the mainboard. I want to know if i can replace the mainboard with any I9300 mainboard even if it's from UK?

Please post in the correct sections.

3 bumps in less than 24 hours. Stop or I'll report you. Wait for a response.
at a guess i cannot see a reason why not, most likely it would be best if its from an unlocked device(network)
@ previous post - beside the moderators post the other is pointless, if you cannot help then dont post,leave the mods to do there job or press the report button instead of trying to scare people away with threats of reporting
if someone requires help and his post is pushed more and more down the list in the index by other post he will feel that for a chance to be seen it needs to stay at least on the 1st page
ive experienced it myself

it doesn't matter, rules are there for a reason
The mobo in the gt-i9300 is the same. You'll get a different imei if you're fitting it yourself.
Have you asked for a quote for the repair from samsung / service centre/ mobile repair shop?

guidelines are there for a reason,if someones new to the forum then they wont know the rules. your post was just as bad as his pointless ones, your not a moderator so it would of been acceptable and within the rules for you to press the report button

Help?!

I have a problem with wifi signal ...
How can I fix a signal ..
I have two motherboard Samsung Galaxy S2 i9100
you help please
If someone can tell me where is the motherboard wifi
1) Questions/generic requests for help belong in Q&A.
2) A title like 'Help?!' isn't acceptable. Titles need to be somewhat descriptive of the problem you're having or the question you have. Many people won't even read your thread in the first place with a title like that.
3) You don't exactly give us a lot of info which would enable us to help you. What rom/kernel, when did the WiFi stop working, what have you done with the phone/flashed recently for starters.

[Q] Can replace i9305 motherboard with i9300? Please help!!

Hello,
and thank you for taking your time to look in this thread. first, moderators, please move the thread if this is not the correct section and second, I searched a lot on google but all there is replacing lcd or trying to get i9305 motherboard into a i9300.
I have a i9305 model and it got heavy fall from my hand and I took it to samsung and they said it needs a motherboard replacement as it has cracks on several spots. and they said i9305 motherboard would cost around 280$ as of right now, I cant afford that much amount and while I was looking for it for some bargain, I saw there are lot of i9300 motherboards for around 120$ on ebay and other retailers. so as far as I know, most of things are same in these 2 models except for motherboard and antenna. so I thought of trying to minimize the cost by replacing i9305 with i9300 motherboard. and I seek advice on is this possible and what else would be needed??
again thank you, and help me please.

I'm not really sure, but if it is possible, you'll probably loose the 2 GB of RAM.

Yes sir, I have been using xda for lots of reading and I know the rules. I saw those threads and I have read each of them.
first google search brings is replacing about display. and again front panel.and then about upgrading s3 to s3 LTE. and then there is only one thread identical, http://forum.xda-developers.com/showthread.php?t=2451777, but it only has 2 3 replys of doubts. So thats why I posted again. Sorry if its against rules. so if you think it is aginst, please close this thread. or I really hope for some help to get a i9300 motherboard into i9305 casing. thank you for taking a look.
