Thumbs up Danger ahead

Hello everybody,

I wanted to warn you, I followed this guide and after doing the root procedure my phone is bricked DEAD.

Won't turn on, won't do anything, not even charghing when power plug is connected, I just killed my phone after about 30 minutes of ownership. :/

PLEASE WAIT A LITTLE BIT BEFORE DOING THIS.

My phone is a grey ZTE Grand S II (NBA Edition, from what I see on the box...).

Does anybody here have an idea HOW I could get this back from the dead?



*** UPDATE ***

I was able to make it work!! Sorry for sounding so alarmed before... I was in panic mode.

If this doesn't work at first please try it on another PC, or switch USB port, and make yourself a big favor by using this:

http://visualgdb.com/UsbDriverTool/

to install your Android ADB driver.

The ZTE Grand S II (S291) is a GREAT handset and I hope the devs get interested because it's one of the BEST prcie/value ratio around...

Got it for 280 Ä on Aliexpress...

Thank You.

S.

Oh , that's not good , but no one bricked the phone to time...
But please look at the titile, have you the ZTE GRAND SII (s251) or the ZTE GRAND SII LTE (s291) because they're completely different phones.

Default Difference?

Hello Jozco,

I don't know, but I finally managed to get it back from the dead, by removing the battery and re-connecting it to the power plug, I can now turn it on again...

In About phone under model number it says ZTE S291.

I found something strange, when I issue a "adb reboot bootloader" command the phone goes off and dead, I have to detach the battery to be able to turn it on again... any ideas?

The phone has a NBA logo on the box, a gray cover, and I got it here:

Do you have any clues, I'm going crazy...

THANKS!

S.

Oh so , that’s seems to be only a ADB driver problem, had it also , because i had a lot of phones to flash , my drivers were mixed up...
just download this: http://visualgdb.com/UsbDriverTool/
install it , open it , plug your phone to the pc , you will see ZTE Handset ADB Interface click on it and under Android ADB driver click install , this will install the universal ADB driver it should work.

I hope we get your phone rooted

I did the steps you suggested but that didn't change anything

The driver situation is ok, as you can see from the screenshot, yet, it WON'T reboot in the bootloader.

Whenever I issue a "adb reboot bootloader" it simply dies... and I have to remove battery.

Obviously I can't make fastboot work this way, therefore I can't move further, any tips?

Thank You!
