That website just stealing my work, don't link them.

You have to Unlock your Bootloader first:


Then FLASH my TWRP
Then follow instructions in the first post of this thread to flash the ROM.

Hello. After installing the firmware without additional applications, the c6833 phone in a sleeping mode drains the battery by 15-20% per night. Moreover, the official firmware consumes 2-3%. Is it possible to solve this problem?

Microphone doesn't seem working.
Error comes up and the recording app shuts down.

Dear @tarkzim
Is it possible to add virtual RAM to this ROM? Like Xiaomi and Samsung phones, which have increased the user speed of their mid-range phones by increasing the amount of RAM.
Thanks
 
oh man u saved me!!! after wanderin fo 2 days, finally this rom worked on my C6802, great job! Wish no bugs, but if any will inform you.

----------------------------------
Update:
I lost cellular network although the IMEI is intact, Wifi can't connect, I, working on the wifi for 2 days now, realized that one of the problems is that the MAC address is invalid, I even used "MAC Spoofer" to change it a valid one but still nothing!
----------------------------------
By the way I have to mention that I downloaded open_gapps-arm-11.0-mini-20211113 but the size of partition is small for it after flashing this ROM. I even added a "gapps-config" file in gapps exluding many apps but still coulden't install it, currently busy solving WIFI and cellular network, afterwards I may download smaller versions of gapps to check the results.

@ml13 Are you sure you have downloaded correct gapps? Same file works for me perfectly fine. Could you try micro version? Or just do not flash apps and then try if the rom works for you.

    Introduction
    LineageOS is a free, community built, aftermarket firmware distribution of Android 11 (R), which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
