How to Update Yureka YU to CM 12.1
Here I am providing different videos for updating your yureka yu .
1. For Normal device that are not rooted and are on stock android .
2. For Devices with CM 12 updated and android version - 5.0.2
Above video is for those devices that are not able to install update on their yureka yu directly due some reasons. So you can download the update from link given in description of video and flash it using cwm. This will not softbrick or hardbrick your phone .
3.For devices that are rooted and are on CM 12 and android verson - 5.0.2 and also for those who are getting incremental update for CM12.1 but are not able to install it due root or any other reason
There are no videos currently for this. So here is what you guys can do to update it to CM 12.1 .
First of all you can try watching above video and download the update and flash it using twrp . But this may or may not work as i myself was facing problem doing same.
So what I did to upgrade to CM 12.1 is first unroot my device by watching the above unrooting video ( How to Unroot Yureka Yu ) and then your device will get softbrick for sure .But dont worry then watch the video for unbricking your device (How to Unbrick Yureka YU which is softbrick) .
After this your device will get to its original state but there is one problem that is for only those who are getting incremental update.People getting incremental update will not be able to update their device even after this step because they will download the update and go to cwm and when apply for update their update will fail . So what everyone in this stage can do is to download the 674 mb update from above video description and then get into recovery and apply update and select the file from storage and update it and then wipe cache partition .After that reboot your device and boom your are updated to CM 12.1 and android version 5.1.1 . Here are screenshots of CM12.1 from my device after following above steps.
