"Invalid Serial Number" during flash

Postby Lyy » 30 Apr 2017 21:45

Hi !
I'm trying to flash an iphone 6, but i'm getting this (attached) and I don't understand the error.
I searched on the forum is someone had the same error but I found nothing.
Is there something I can do or is my iPhone lost ? :(

Thanks !

Dear,
Thank you for your information.
Did you update your 3uTools to the latest version?
And please try to enter recovery mode and then easy flash. And you can also try to take out the sim card and flash with 3uTools.

Hi,
Thanks for your reply !
I used the latest version of 3uTools, I put the phone in recovery (and also tried in DFU) and tried easy flash. There is no sim card in the phone.

Okay, please kindly the drive of your pc: Please right- click "Computer", then click "Magage" → "Device Manger"
(Check whether there is any warning, if there is, please update the drive.”, and check if there is any unknown abnormal circumstance.

If you meet the same error after trying the above steps. There may be hardware issue on your device. You are suggested to get a repairman to check your device.

Dear all,
If the same error still exists when you enter DFU mode to flash, it would be the hardware issue.
