Thanks Meter: 0

to begining, i'm sorry for my bad langage, i'm not english and it's difficult to speak on this tong to me.

I've Samsung Galaxy S4 i9505 on 4.3 with IMEI null/ null. I try to fix it with EFS Professional but i can't because i've an error.

- My phone is rooted
- I've Busybox pro and i use on v. 1.20.2 (only it work better)
- I use EFS Professional 2.0.80 (other don't run adb)
- 'ive S4 driver
- I've EFS Floder save with root explorer but it was save after imei null/null problème and few restoration.
- I've already try to flashe with my countrie firmware

I try to write my imei with EFS pro and i proccess like that :

1 - Run Busybox and wait all is load
2 - Run EFS professional
3 - autoriser l'accès avec l'option de débogage usb
4 - Wait result

That remains blocked in " checking device status..."

Have you an idea to my problème ?

2 - I've à second question, i have an galaxy S3, can i increase his imei, write the imei of my S4 and copy his esf folder on my S4 ?
3 - If i try to update on 4.4.2 to keep a chance to find my IMEI, can i Downgrade on 4.3 after ?

Thanks you for advance
