[YU Yureka General] sunny765:
Thanks! I'll let you know how the procedure went!
[YU Yureka General] ramu2k06:
Hi tirta.agung,

My yureka was rooted and using Blisspop V3.2 lillipop based Custom ROM. I installed TWRP Custom recovery also for flashing this ROM. For flashing this ROM I have completely format the system, cache, dalvik cashe etc.. Presenly I have no backup of Factory ROM i.e. CM Kitkat or Lollipop in my mobile.

Now My doubt is what is the process to downgrade to Kitkat with this Blisspop ROM. I wishing to downgrade to CM Kitkat Factory ROM which is came with my mobile. Can I Do this with the above mentioned commands and process. Is it requires to download and keep the CM 11 official ROM in that folder due to I have no backup of this.

If there is any other process for this pls Can you tell me the step by step other process for this. one user replied that directly run this commands (with Blisspop ROM). Is it correct. Kernels / Partitions support with this ROM (I dont have the much knowledge about the Kernels and Partitions).

Iam very thankfull to you for your reply ASAP. Thanks in Advance.

Ramu. A

Iam very thankful if any other member help on this issue.
[YU Yureka General] skumar9296:
You have to do the same process as instructed in this thread.
[YU Yureka General] ramu2k06:
Hi Friends,

With the help of this process i have downgrade my mobile from Blisspop Lollipo custom ROm to Official KitKat and running smooth. and also after downgrading to KK iam get the notifications for Lollipop Update also, But Iam not updated due to various bugs in this. (Actually I have doubt that is it supports the OTA updates, But it clears that we can get the OTA updates also from CM).

Iam very thankfull to every member who advises me. My special thanks to tirta.agung who make this easy process and also my thanks to sunny765, Titokhan, skumar9296 who give their advises. thanks alot.
[YU Yureka General] sunny765:
Thanks to the procedure mentioned above, I was able to get back to Kitkat on my yureka. As much as I loved the sleekness of lollipop and it's material design the minor bugs were too much to handle for me. Kitkat is where my heart was and is right now. Thanks for all help and I wish you well in life!
[YU Yureka General] Abhishek467267:

[YU Yureka General] Alienoid:
Boss hats off to you!! In the process of applying CM 12 incremental update i messed up somewhere by flashing the the new signed zip via stock recovery, and my mobile would display the cyanogen boot animation but won't go beyond that. So i decided to go back to kitkat and well........ it works flawlessly no problems whatsoever...Thanks

Oh and just in case i am not getting an update for Lollipop notification i don't know why..and i would really appreciate someone making a nice detailed post on how to apply the incremental lollipop update.. Thanks again!:)
[YU Yureka General] aditya.yu:

One of my friends had his yureka shut off in the middle of an update. He was already on lollipop and was upgrading to the new build when his phone fell and he was not able to boot into the is.

Best way to root the phone after downgrading to KK by this method?
[YU Yureka General] Simranchaani1:
Same question

Hey :)

I am on Blisspop v3.5 and TWRP custom recovery installed. I want to ask that can i directly start downgraging to kk or i have to go to cm12s first?

Also, do i need to install cyanogen stock recovery, to go through the procedure or twrp is okay???

Plz reply
[YU Yureka General] sunny765:
You can directly start downgrading. I did it and it worked amazingly.
[YU Yureka General] sahajyu:
Hiiiii are you downgrad kitkat
[YU Yureka General] vithlani2:
does this will wipe my internal storage???

becuase maybe there is a command for unlocking boot-loader and unlocking bootloader will erase all the data...

and i am on softbrick so i hope this guide will work for me...
[YU Yureka General] vithlani2:
Downgraded successfully but losed my all of data from internal storage which was much important for me

waiting for device

hello,

when i copied first line in cmd its shows that waiting for device...
[YU Yureka General] heisenberg-001:
You mean "fastboot -I 0x1ebf oem unlock" ?

You sure you are running cmd in fastboot folder? Check you cable.
[YU Yureka General] akki.mittal:
yes sir.i have unzip all the files in one folder.and start cmd in the folder.
[YU Yureka General] heisenberg-001:
I guess yours is windows. What about the driver? Open device manager and update your driver while its connected in fast boot mode.
[YU Yureka General] nilgg:
nilgg

its works thanks
[YU Yureka General] sangalaviral:
Can you please tell me after downgrading what method shall I use for rooting?

I had been asking this for many days now.
[YU Yureka General] heisenberg-001:
Rooting is simple, you need 3 things

1. An unlocked bootloader for installing a custom recovery

2. A custom recovery(cwm or twrp)

3. A superuser file in .zip form in your sdcard. (you have to install this file through a custom recovery there by gaining root access.)

there is a detailed explanation here, see this link

http://xdaforums.com/yureka/general/16-1-2015-t3004724

You dont have to download the fastboot drivers again, you can use the previous one that you used for downgrading.

Just place the cwm recovery image inside that folder and run the commands.

Good luck.:good:

Just wondering :confused: why do you want to downgrade?. :cowboy:
[YU Yureka General] sangalaviral:
Thank you so much for a reply. Just one clarification I will be using twrp for Kitkat or lollipop?
[YU Yureka General] heisenberg-001:
Hey.You are confused.

There are lots of recoveries out there. Cwm, customised cwm's and twrp. Doesn't matter which one you use unless they specify. "But make sure its the latest one".

I recommend cwm for this one.

I found twrp-2.8.6.0 has lil trouble booting up.
[YU Yureka General] kailashnj:
Thanks a lot for your guide, I was able to downgrade to KitKat without any issues. Now i will be happy with my phone as its working as it should.

How i flashed this files bcoz i cant get into recovey mode or fastboot mode....phone is fully dead...any idea...plzz i m in trouble ...can u tell me the all steps what u taken

Thanks for reply
[YU Yureka General] raj7749:
go to fastboot mode by removing battery then plug the battery again "dont turn on the phone". connect the phone to pc by pressing UP key only.. the device will boot in fastboot mode, even if nothing is shown on screen the device goes into fastboot mode... check it by entering this command fastboot -i 0x1ebf devices..

if no output comes on the console, then the device is not in fastboot... if the device gets into fastboot then use fastboot image from cynogen support " above post".. if all does not work, you can always book for replacement under warranty, as rooting or installing custom firmware does not void warranty on yureka phones..

fastboot -i 0x1ebf devices

Right now using Chrome. I think its using lot of battery, is there any other browser which uses less battery? or all the browsers are same..
[Nexus 6 Q&A, Help & Troubleshooting] simms22:
first off, there's no such thing as a best browser, there's only the best browser for you. we all have differing opinions to what is best, as we all jave differing needs. whatever fills your need the best would be the best browser for you. personally, i love the aosp browser. as its full, lightweight, and uses very little battery(tiny amount compared to chrome).

[Nexus 6 Q&A, Help & Troubleshooting] CeltiKore:
it all depends on what yore trying to aim for entirely and what your willing to give up as well for better battery and more lightweight. Theres many browsers available that are what seems to be what your after. There is UC Browser Mini, Opera Mini, CM browser (no not cyanogenmod browser), Ghostery Privacy Browser, etc. Only way to tell for sure is install them and see what you like better. All can be found on play store
