ReplyDeleteWell the problem with my phone is that it wont run a sim card and shows no IMEI and no Baseband. I just bought it 5 days ago . When i ran it for the first time everything was working perfectly even the sim card. But afterwards i charged it for 3-4 hours and when i switched it on this problem occurred.
ReplyDeleteNo error mean there is no problem with this tool
ReplyDeleteI'm sorry to tell you that this tool and any other tool (backup/restore efs) won't help you to fix your IMEI
ReplyDeleteThis tool helps only if you have a backup file

ReplyDeletehello, my phone has a region lock and i tried to unlock it by rooting the phone. It started and failed several times before it finally got rooted. After that when i dial *#06# imei appears as it is but when i dial *#0011# i get IMEi certi fail. I reverted back to stock ROM, in fact the official correct ROM but it still fails. Initially i get a Sim Network Unlock Pin Dialogue box but now it doesn't show up. I dont know whether it has something to do with the IMEI certi fail. Please help as i Now have a code to fix this region unlock. Thanks. Awaiting reply.....
