After to have tried, result isn't good for me like I wrote below. I don't know the cause. It fails at 71% after another check of package. I have several suspicious.
Suspicious:
- My phone. I've always had some problems for anything with it - example: my way to root it doesn't work for me, even all methods, I have to format the data before.
- The package size: 796 Mo
- Maybe I should have to wait the tomorrow day (like certains)
I give up for now, I took a long time to get it works again, mainly to find my old tuto to root it properly.
About of that, if someone has the same issue than me with his phone. He want to come back on the rooted B560 after fail the B581. And he has lot of difficulty to root his phone... ASK ME! I've a good tuto.
Another reason which does me to give up, I'm not sure that I could root the B581 because we can't install the update_full_NXT-L29xxxB581_hw_eu.zip file via TWRP. And me, I need to can install this file in order to root my phone without risk of bootloop.
However thanks for this tuto!
