I have tried a lot to unbrick my Lenovo Vibe Shot. Now I am helpless and looking for some workable solution:
I used Lenovo Smart Assistant to download a proper firmware so it turned out it is: z90a40_USR_S363_1606250500_Q202533.1_ROW.zip
I tried to use Lenovo Smart drive assistant to update ROM or Device Rescue, but both wont detect phone. The phone default Lenovo recovery can be loaded by pressing VOL+, VOL- and power button, and then releasing power button when logo appears. I used an Update.zip in 8GB mem card and used the option: ‘install update package’ then it complete the process 100% I was happy that I was going to get my phone unbrick
After trying a lot of things I realized the actual problem is with partition table of its internal memory, so whenever I try to connect phone via USB cable to PC and turn it on simply with power button or trying with fast boot mode (VOL - and VOL + then pressing power), it shows all the following partitions that are write protected. So is there any way I can forcefully remove the write protection and delete all these partitions ??? I have tried with Disk part as well but no luck. Plz help PS if some one wants to read more about this problem, plz check following thread of mine that is still unreplied: http://forum.xda-developers.com/android/help/unrbick-lenovo-vibe-shot-z90a40-t3505789
