Go to the overcome ROM thread. There's a link there to a guide. Next time search the forum before you ask, and if you don't find anything by searching, post in the correct forum.

Where's the mod that likes your posts so much? Maybe that isn't you, slack04, that I'm thinking of. Sorry if I confused you with someone else.

If you have a nandroid backup of your stock rom, just restore it then flash stock recovery with odin. If you don't have a nandroid backup then your need an odin flashable stock rom.

well, that is the forum and WIKI for your specific phone and model, it has a Q&A thread too, so best to post your Question and explore there, as answers will be correct and accurate and you should explore those other threads to understand and operate your phone better.
the posters on this Q&A, do not have such threads , thats why they post here.

1) You can only not post on dev section with less than 10 posts. You can post in general just fine. In fact, you posted this thread in general (which was the wrong place actually, questions go in Q&A, except IMEI questions, which go in my thread )
2) Your question is not different in any way. If you take the time to read the thread I suggested you read, you would know that.

You are contradicting yourself here. If your IMEI was 0049 then you did have an EFS / IMEI problem. My thread explains WHY and also WHAT you must do to keep your IMEI correct, so it answers all your questions.

[Q] Flashed 4.1.1 over 4.3 on i9305, suck on firmware screen!

I've looked at all the other threads regarding this issue but nobody appears to have been as stupid as me and done what i have done!!
I wanted to unlock the sim on the phone as i am selling it.
The forums said to downgrade to 4.1.1 using odin which I did (phone was on 4.3)
The phone is now stuck on the firmware page
I have tried flashing 4.1.2 using odin but it fails
Kies won't connect to the phone at all but odin does
Do i now have a brick?
Many Thanks in advance
Wrong phone and wrong forum..
Post your questions in your respective forum for your phone..
