How To Downgrade Yureka To CM 11 (Kitkat) From CM 12 (Lollipop)

8/5/2015

16 Comments

 
After long awaiting of Lollipop update to Yureka, the device recently got a CM12 with Lollipop 5.0.2. Soon, after Yureka users started updating the device to taste the new CM12 with Lollipop. But the long awaited time for update was wasted as the device started behaving abnormally with two many issues. 
Cyanogenmod 11
The issues are :
  1. Black screen during calls ( Proximity Issue )
  2. Unable to sync Google data/GPS Force close/ Unable to download apps
  3. Low Sound
  4. Slow phone/ Lags in transitions
  5. Heavy battery drain
  6. Issues while gaming
  7. Heating problem
  8. Frequent reboots

Due to these problems, users are unhappy with Lollipop and want to get back to old CM 11 ROM based on Kitkat. But the major problem is that if you have updated your device to official Cyanogen OS 12, then you CAN NOT DOWNGRADE at all. That's because Lollipop is a 64-bit OS and KitKat is 32-bit OS. So if someone tries to downgrade then they will brick their device.

To overcome this problem, a senior developer in XDA has given a solution that will help to flash your device to stock kitkat version. 
Disclaimer: We are not responsible if this procedure will brick your device

How To Downgrade Yureka To CM 11 (Kitkat) From CM 12 (Lollipop)

1. Download CM11 KitKat factory image “cm-11.0-XNPH05Q-tomato-signed-fastboot.zip” (fastboot flashable package) or from here.
2. Download fastboot.zip from XDA forum. Extract the zip, it contains Fastboot & ADB files.
3. Copy both the files in an empty folder.
4. Open "Command Prompt" from the folder where you extracted all the zip files. To do so, open the folder and right-click while holding down the 'Shift' key. Then choose "Open command window here".

5. Boot Yureka into fastboot mode – To do so, power off the phone. While pressing the Volume UP key, connect the phone to PC/Laptop with USB cable. The phone should show "Fastboot Mode" screen as shown below.
6. After connecting the phone, go back to CMD window that you opened previously and type all the below commands (ONE LINE AT A TIME).

Note: Enter the commands in the exact same order as stated below. Make sure to wait for “OKAY” confirmation after every fastboot command. (Use copy-paste to enter commands in CMD)
fastboot -i 0x1ebf oem unlock
fastboot -i 0x1ebf erase modem
fastboot -i 0x1ebf erase boot
fastboot -i 0x1ebf erase recovery
fastboot -i 0x1ebf erase aboot
fastboot -i 0x1ebf erase abootbak
fastboot -i 0x1ebf erase hyp
fastboot -i 0x1ebf erase hypbak
fastboot -i 0x1ebf erase rpm
fastboot -i 0x1ebf erase rpmbak
fastboot -i 0x1ebf erase sbl1
fastboot -i 0x1ebf erase sbl1bak
fastboot -i 0x1ebf erase tz
fastboot -i 0x1ebf erase tzbak
fastboot -i 0x1ebf format system
fastboot -i 0x1ebf format userdata
fastboot -i 0x1ebf format cache
fastboot -i 0x1ebf flash modem NON-HLOS.bin
fastboot -i 0x1ebf flash sbl1 sbl1.mbn
fastboot -i 0x1ebf flash sbl1bak sbl1.mbn
fastboot -i 0x1ebf flash aboot emmc_appsboot.mbn
fastboot -i 0x1ebf flash abootbak emmc_appsboot.mbn
fastboot -i 0x1ebf flash rpm rpm.mbn
fastboot -i 0x1ebf flash rpmbak rpm.mbn
fastboot -i 0x1ebf flash tz tz.mbn
fastboot -i 0x1ebf flash tzbak tz.mbn
fastboot -i 0x1ebf flash hyp hyp.mbn
fastboot -i 0x1ebf flash hypbak hyp.mbn
fastboot -i 0x1ebf flash boot boot.img
fastboot -i 0x1ebf flash recovery recovery.img
fastboot -i 0x1ebf flash system system.img
fastboot -i 0x1ebf reboot-bootloader
fastboot -i 0x1ebf oem unlock
fastboot -i 0x1ebf format userdata
fastboot -i 0x1ebf format cache
fastboot -i 0x1ebf reboot
7. After reboot wait for a while. Voila! Your device should be running on KitKat.
This is an easy way and shouldn’t take much of your time. After downgrading to CM11 you might soon get the OTA for Lollipop that you can simply ignore if you don’t want to install it.

@khan Wasim, Thanks for following my post. Please use the Micromax ADB drivers to install on your Asus.
The answers to your questions are:
1. Partition will be same as kitkat - 12 GB
2. Yes
3. Yes but with rooting is guess.

Hope this helps you....

Hi Shoeb,

Can you please answer my question related to Yureka?

1. If I downgrade CM12 (64bit) to CM11 (32bit) will it cause Hardbrick?
2. What precautions should be taken care while downgraing above mentioned requirement?
3. Is the method you mentioned in your thread is fool proof?
4. I can not move my apps to External SD card even I use Link2SD what should I do? It shows message SD card is emulated from internal storage?

Please reply ASAP I want to flash lollipop and my internal storage is running out...
