[YU Yureka Original Android Development] Panchajanya1999:
F.A.Q. --

1. My WiFi doesn't works after flashing this kernel.

Extract wlan.ko from the .zip of kernel (located under system/lib/modules/) and place it in root/system/lib/modules/ overwriting the one already present there. Then, set the permission of the file to rw-r-r and reboot the phone. Use ES File Manager with Root Permission to do this.

OR

Place the .zip of the kernel in Internal Storage and then re-flash the kernel.

OR

Check free space in /system partition. Atleast, 25 MB of free space should be there in /system partition as less space prevents the wlan.ko file to get copied successfully.

OR

Flash the latest version of SuperSU.

OR

Change the ROM. :D

2. Which Android Versions does this Kernel supports?

AzurE Kernel supports Marshmallow and Nougat ROMs. However, not every Kernel Version supports every Android Version. Check Changelog of the specific Kernel Version before flashing it.

3. Does VoLTE works on this Kernel?

Yes, if the ROM supports VoLTE, then this Kernel will also support VoLTE. However, if the ROM doesn't supports VoLTE, then this Kernel won't too.

4. How long are you planning to continue development of AzurE Kernel for Yu-Devices?

As long as I have my Yu Yureka PLUS with me, I'll keep the development active.

5. I have a feature-request!

Well, feature-requests are accepted only when I find the said feature to be having some practical use or substantial positive effect. Whether I include the feature or not, is purely my decision.

6. Why don't you answer my queries? I have asked 10 times already!

It takes much time in developing and testing a Kernel. So, it is difficult for me to keep track of every query too. However, if your query is a genuine one (i.e., not a duplicate question or a question, the answer of which isn't present in the First Post or the Changelogs), then I'll surely answer it.

7. Kernel Adiutor shows blank space in Governor and Frequency Panel of CPU TAB.

When Core 0 gets disabled (due to Core Control or State Helper HotPlug), Adiutor fails to get Frequency and Governor information and hence shows 0MHz in Frequency Panel and Blank Space in Governor Panel. This is normal. In this case, if you need to change Governor or Frequency, then you need to disable Core Control or State Helper HotPlug as the case may be. After this, force close Adiutor and then re-open it. This will make Adiutor get CPU information again. Also, if you don't want to face this situation again, then disable HotPlug Boost Toggle (this will make the kernel to not disable Core 0 and hence, such situation won't arise).

8. The HotPlugs aren't working! After sometime, all the cores come online.

After manually changing the CPU Governor or Frequency, all the Cores will come online even if any HotPlug is enabled. So, you just need to re-enable any HotPlugs you were using in order to disable the Cores again.

9. My whole big Cluster is offline! I can't enable it anyway!

Well, my kernel uses Core Control v2.0 (built by me) and hence, it has the ability to disable the whole big Cluster (including Core 0) if temperature rises above 55 C. When the temperature comes below 55 C, the big Cluster is brought back online again. This is normal and is done to reduce heat. Moreover, if you don't want Core 0 to get disabled, then you can Disable the HotPlug Boost Toggle (available under CPU TAB).

10. The CPU Frequencies are locked. I can't change them. This is a very serious BUG.

I wouldn't call it an issue or a BUG. It is a feature. My kernel uses a Custom Thermal Driver. It reduces the Frequencies to keep the temperature of the Kernel within safe limits. Hence, sometimes, when the temperature is above a certain degree, the Thermal Driver locks the Maximum Frequency so as to lower the temperature of the SoC. However, in my kernel, everything is user-configurable. So, if you want more performance and can bear some heat, then you are free to set the Thermal Settings according to your preference. These settings are available under the Thermal TAB of the Modded version of Adiutor only.

11. I don't have a 1.5A Charger. Should I use Quick Charge or not?

Let me clear this in a simple yet detailed way.

To use ThunderCharge's 1250 mA value, one needs a Charger capable of supplying 1.25A. So, if you're using a 1A Charger and you have set 1250 mA in ThunderCharge, then it won't work. The Charging will only occur at a speed of 1000 mA which your Charger supports.

Similarly, Quick Charge requires a 1.5A Charger for it to work fully. However, this doesn't means that using a 1A Charger with Quick Charge will affect Charging Speed negatively. So, if you're using a 1A Charger, then Quick Charge will draw only 1000 mA.

As for the Dynamic Current Panel, it shows the Value requested from the Charger, not the Actual Value drawn.

BTW, if you are using the Stock Charge and Yu Yureka phone, then Disable Quick Charge.
