Samsung S2 GT-I9100 null IMEI and unable to restore original IMEI number in EFS?
Hi, I have trawled the internet for a fix, many sites tried explaining a fix however only very dodgy. This is a friends device which I have managed to recover to carrier version but seems EFS folder is still corrupt. Do you have a reliable source for 'rooting and super user' for this device, then a decent EFS reader? Thanks
Download a toolkit and on the rooted phone, use EFS PRO app to restore the corrupted files.
If you root your phone, you need to understand that things can go wrong. Rooting is not a process covered under warranty by Samsung, as it can cause issues to your phone that normally wouldn't happen if you didn't root. There is a way to return your IMEI number to normal; however, this requires unrooting your device or flashing the stock ROM again, since you likely didn't back up the IMEI number before you performed the rooting process. Plug your device back into your computer and run ODIN again. Download the stock ROM here. Then, follow the instructions in ODIN to flash the stock ROM onto your device to return your IMEI number to normal.

Please, how can I rewrite my IMEI on my GTI9100?
I have a fake IMEI and I can't repair it, I want to write my IMEI that is labeled at the back of the phone
You need to repair your EFS files as suggested in the above answer using the toolkit.
How to fix IMEI, my problem is that the network won't appear, I have tried several ways but still it can't fix?

Install a Custom ROM if nothing else is working. You still may need to use the toolkit method to repair or the dial method to assign the IMEI again.
Can an update of Android 4 to 5 be reverted?
Actually, I have updated Android version 4 to 5 of my Samsung Galaxy S2.
It can be reverted but can also cause numerous problems such as those posted in the above answer. First, why do you not like the newest version because things like battery draining faster can easily be corrected? Try to determine what you are not liking and set up that newest version to your preferences.
