I think internal memory is not accessible without root…I have already formatted my SD card using Marshmallows new feature so twrp is not mounting it at any place that I know of….At what place exactly are you saying to copy the files
You can place the File in any place Internal of External.
Whats internal of external? I read somewhere that Marshmallow basically encrypts the SD card when it formats it as internal ext4 partition so till someone decrypt those keys it will be difficult mounting it. Anyways I found another way 😀 I did it the ADB sideload way. Just need the minimal ADB and Fastboot setup. Drivers can be downloaded using adbuniversal_v1.0.
Assuming your file is "filename.zip" and you have copied it to the minimal install folder.
After that you need to boot mobile to recovery >> Advanced >> ADB sideload(for TWRP). Connect with USB on PC and pass the commands "adb sideload filename.zip" from a command window open in the folder where minimal setup is installed. And that file will get installed.
Will I be able to install future OTA updates if I root my device?
Nop you can't
Then how do I install future updates? Will I need to wipe in order to install official updates?
For updates you need to install the stock kernel and unroot your device with stock firmware.
Thanks.
One more question please, its off topic though, when will Android 6.1 begin rolling out?
No one know 🙂
Please make a video then it will be very clear.
From where I'll get TWRP
you can get it from here http://forum.xda-developers.com/canvas-a1/development/twrp-android-one-sprout48-t3313657
why to flash thunderzap file ?
without this you can’t root it.
Is it important to install TWRP? Can we root without it?
Yes it is important
