I've got a friend who got a new Captivate from the US. And he flashed CM10 right after getting it, without making a backup of the efs folder. Now, the efs partition is completely empty, and of course it says "Unknown baseband, unknown imei", etc".
I've looked around, but all the imei restore methods seem to require at least one efs file. However in this case we have none.
Question for the apple users out there. So a relative of mine needs an iPhone 5 for his new post in southeast Asia. He bought an iPhone 5 off eBay which stated it was unlocked. He got the phone, and it's a sprint iPhone 5 running iOS 7. He tried using imei.info to verify the unlock status, but imei is coming back unknown.
I have my device samsung s3 galaxy.
Instead of the original imei erased and written in a different IMEI.
I want to install a different rom or custom rom now I want to install the network going. we have to throw again imei with spt box. The most robust way to back up efs file? original or subsequently thrown can make the device can erase imei?
