Wenkey

Declaimer:  I am not responsible for your device .if your device got bricked and warrenty may be void.

I'm not telling you the way to unlock bootloader it may vary from device to device.

In this I'm gonna tell you about how to install custom rom via TWRP( Team Win Recovery Project)
Their are so many out their in the world of custom like Orange fox,Twrp,...E.t.c

Prerequisites: First we need to unlock bootloader of our smartphone, minimal adb drivers and personal computer.

1.Unlock bootloader using device specific way or in my case I unlocked from minimal adb drivers.

2. Assuming you are successfully unlocked bootloader , now then reboot to bootloader

3. Now connect mobile to pc using usb cable and open cmd prompt , (You need to open in minimal adb drivers folder by pressing shift and right-click you can find in menu .)
 Now type "fastboot devices" if it show any number and device name then your drivers are installed successfully.then proceed.

4. Now download Twrp  choose your device and download latest twrp file (.img format)
If twrp not found search adding your device name in addition with Twrp. search for device specific channel in telegram for help.

5.Assuming you found twrp now place the file in the minimal fastboot  or adb drivers folder .

6.now open cmd prompt in that same folder as above enter " fastboot flash recovery 'your twrp name '.img " (don't place quotations it's just for understanding)

7.if you got 'okay' bingo! You finally installed twrp in your device now reboot to recovery.

8.Assuming 2 conditions 
a.your device has encrypted that twrp has unable to decrypt it
b.your device encryption successfully decrypted by twrp

9.if twrp unable to decrypt your data then you need to format your device by clicking format in twrp 

Screen may look like this....you need to click cancel then
10.click on the wipe button then click on format data. Now swipe  and then reboot to recovery.if your device successfully decrypted then no need this process.

11.Now need to back up your OEM before flashing custom rom 
12. Now the step is downloading custom rom. Now we can play with our phone like crazy.

13. Custom roms are basically 2 types:
a.aosp based custom roms with or without gapps(pixel experience,aosp extended...E.t.c)
b.caf based custom roms with or without gapps(panandroid,revenge is...E.t.c)

14.Before downloading any rom check whether it has inbuilt gapps or we need to seperately

15.if no gapps in rom we need to download it from here prefered ones are pico and nano

16.more stable and updated custom rom is Lineage open the link and search for device and download it and gapps

17. If gapps is present no need to download seperately.

18.For rooting your device download magisk(optional)

19.now copy them to phone's internal storage using usb cable bingo!.. now we are ready to flash

20.click Install in twrp home page select for the rom and gapps afterthat then magisk. If your rom has inbuilt gapps then no need to flash gapps just rom and magisk

21.Wait untill the process completes. If any difficulty refer to channel of your device.

22.Assuming flashed rom, now  reboot your device it gonna take a while( 5-10 min) be patient 

23. Your device completely installed with custom rom congratulations!

Note : if your device successfully decrypted with Twrp your data will be present after flashing the custom rom

EAS vs HMP kernels

wenkey EAS: Energy Aware Scheduling     It is an incremental update to the existing Linux power management system developed by the ARM tech giant where it places CPU power control directly under the Linux Scheduler.  As we all know that there are different types of CPUs based on the number of cores most frequently used ones are Octa-core and Quad-core CPUs. Based on the task load EAS selects CPU efficient core to get work done. Nowadays, each soc contains BIG and LITTLE cores, Big Cores are tweaked to high clock frequencies in order to achieve max performance and Little cores are power-efficient cores these are  clocked with low Frequencies.          EAS uses a Model of CPU energy consumption or simply called EM to optimize the task scheduling on the BIG or LITTLE cores or DynamiQ platforms while meeting compute requirements.EM gives the CPU topology to the scheduler and provides power cost information of tasks running on each core of the CPU at each available frequencies. EAS uses EM

AOSP VS CAF

Wenkey Hello guys! Today I wanna discuss you about the difference between Aosp and Caf based custom roms. Now a days, everyone shows interest in using Stock android besides customized skins. At first, 1) What is Aosp? Where is it originated from?Is it secure? AOSP - Android Open Source Project It is an developed by Tech Giant called Google, Basically Android is an operating system based on Linux kernel. Through it is lite and modified to use in small devices efficiently AOSP is a skeleton of android, It can support any smart device including smart phones,smart watches...e.t.c. Aosp uses general HAL's( Hardware Abstraction Layer) which is compatible with all kind of hardware of the device. HAL' s include connection of  drivers of kernel with the hardware of the device. The HAL uses common app API to link bluetooth, microphones with kernel. AOSP is different from the Pixel phone's operating system. As every OEM makes their adds their own customised skin like miu
