Working on it bro if I had one of them phones it would be eaiser to troubleshoot.

What is your baseband?

I'm hoping those in the Canadian regions are all on the same one I'm running a binary analysis against other ROMs reported to work with these phones.

The Canadian ROMs which work are the key to solving this very strange bug.

Please remember this is a port.

I want everyone who reads this to report their baseband because I'll be able to tell which ones work and which ones don't.

I have seen this happen on my phone two times and I was able to resolve it by doing a full wipe and then flashing the ROM first and then flash baseband and then flash data_fix feature flash I provided some with links to and then flashing kernel all back to back and noticed the eri and efs sync only when this is done on the initial boot from flash when the ROM builds the efs folder structure and only when those steps are done all together did it fix the null Imei which would in turn prevent data from working.

If you reboot in between flashed zip files it will not do anything different then it's already doing because by then the wrong efs folder structure is in place.

I am not sure where the radio zip is for your specific baseband but when I get home I'll find it and upload it to posts for all who need it.

I have researched so many ROMs having this same issue and many reporting that using root explorer worked when restoring the efs folder and resetting the permissions on it to the same values as the stock and rebooting. This actually worked for me on one of the two times I've seen this the other method fixed the issue.

With so many people trying these things and having such a high failure rate I'm sure the actual solution to this is really simple I just need to find the needle in the hay stack.

I prefer the ROM contain the files needed instead of flashing files the way I mentioned but the goal for me at this point is troubleshooting a phone I have never seen and getting one of these to work because if I can do that and understand what cures this then I can provision the ROM with that fix.

My approach has changed with this issue and instead of releasing a ROM for everyone to grab I'm going to release to the ones dedicated to testing the beta versions until we have resolved this.

The outcome of this research will produce valuable information on all ROMs compiled which exhibit this same affliction.

My suggestion to those who are surprised by this and are shocked this issue remains is to wait this out before flashing anything more.

Once we have reports of even one success other than me which does not count because there is something different about these galaxy s 3 's which is the first thing I need to understand.

Please wait until I have a solution which will work. If you say you'd like to test pm me as some have already today and I'll be sending the links with instructions to those who volunteer.

Otherwise it is not my intention to disappoint or waste anyone's time but to produce and release a 100% working ROM for all to enjoy.

I'm only as good as the information I apply and test and I've tried a lot of different things which were reported to work for some situations and not others and I figure the methods are phone specific otherwise it would be reported to work 100% on all makes and models and many of the posts I've read claim otherwise.

My attention is only on Samsung S3 variants and nothing more, but that's not to say when this is resolved it won't help other devs down the road.

This effort requires blind commitment, determination and a ton of willingness and faith to resolve not just because its perceived to be such a Hugh issue and it actually is but because it's a widespread problem in some ROM development methods and clearly the method I'm using it not the right one for the Canadian phones. This outcome will change the ways ROMs are packaged by others.

Thanks for suffering through this.

Each and every persons experience and results with this effort are very important.

Quality is very important to me.

Later,
