    2. andy, great work! i've been looking for someone who could give me a more reliable technical know-how on rooting/unlocking the S90 (Sisley). i, however, would like to make sure (*even though i've rooted and unlocked many devices for friends) by asking (you) the expert, if my phone specs are the same one you have worked on. they are:

      Lenovo S90-A
      Android 5.0.2
      Baseband version: MPSS.DPMN.1.0.c7.7-00039
      BUILD: S90-A_SMART-S111-150527-ROW

      i wanted to follow your procedure since i would like to perform a nandroid backup. also in order to remove some APKs i don't want/need. furthermore, since i'm using Win 10, i may have to see how to work on this on Win 7, but i'm sure Win 10 could handle your procedures quite well. ;-)

      i wish i could pay you back for your wonderful contributions. unfortunately, i don't have a stable job. i can, for example, help polish up on your instructions and pass them on to you for future postings!

      thank you so much,

      bodega1968@gmail.com

    3. hi,
      first thank you for your visit and positive comment. I am not an expert just ordinary guy that like on android.
      yes windows 10 and windows 8 cannot be use on this guide because lack of driver that work on windows 8 or later. for perform nandroid backup you need to install custom recovery twrp or cwm like you can see in http://bit.ly/1SJfl0m, but before can install custom recovery first you must unlocking the bootloader.

      every help will be very appreciate, if you want further conversation you can contact me on email andychin21@gmail.com

    4. andy, thanks for the speedy reply! although i'm now more

      CONFIDENT with your instructions (like 99.9% confident),

      the 1% is the usual 'fear' that we guys have when

      rooting/unlocking and the like, since there's always the 1%

      of bricking a gadget. also because (as it is with all 'new'

      devices) warranty is made void once they know you have been

      tinkering with the phone. as a note, though, i will try my

      chances of test running it on Windows 10, since i don't

      seem (at least i think) see any problems with driver

      recognition, unless you're referring to the more

      complicated driver setup that your previous post showed in

      the DEVICE MANAGER screenshot. if so, then perhaps, i may

      have to find a PC with windows 7, ha, ha, ha... thank you

      so much for being so patient.

      at the moment, i am tinkering with a generic 'nexus 4' that

      came out in the philippines in the myPhone UNO and Cherry

      ONE variants, i'm trying to see what custom ROMs can be

      installed in these devices. ;-)

      i hope that when i have overcome my 1% fear-factor, then i

      will get back to you, though i will be following your posts

      more often now during my free moments. keep up the good

      work and till my next query.

    3. what installed driver are you pointing to?, is it the boot loader?

      Delete
    4. Installed driver on your OS, and when i try this i am using eindows 7. Never try higher windows so if you are using windows 8 or windows 10 yhen maybe it the problem
