DerpFest A13 Tango Update!

Important instructions:

* RUI 2.0 firmware based. So Need RUI 2.0 firmware by @pjgowtham. Get it from main group notes (#firmware_download) or Download it from Realme XT telegram channel.

* Need latest TWRP (OR) OrangeFox (OR) Bitch Black Recovery with RUI 2.0 support. Get it from main group notes (#twrp_download, #ofx_download, #pbrp_download) or Download it from Realme XT telegram channel.

* You need to clean flash with format data if you're coming from A12 or 12.1. It's MANDATORY. So take backup of internal storage before flash.

* You can dirty flash if you're using previous A13 build.

* Flash firmware first then reboot to recovery again. Flash Rom zip, format data by typing yes, Reboot to system. Flash magisk after first boot if you want root.

* Indian users should flash NFC removal zip (otherwise it will drain your battery in background) from main tg group notes( Use #nfc_removal)

* Gapps and Vanilla Builds available (I prefer GApps build only. No support for Vanilla)

* Don't report bugs with vanilla Build

* Need minimum 3 days (or 3 full charging cycles) for things to settle(optimizations). So be patient.

* Users might get widevine L1 support if you're already getting it in RUI 2.0 stock rom. Follow #widevinel1 notes from main tg group.

* Check #widevinel1, #nfc_removal, #firmware_download, #twrp_download #ofx_download, #pbrp_download, #magisk_new #why_format_data, #bankapps_fix, #upi_msg_fix, #battery_optimizer in main tg group notes for more details.

Known Issues:

* FOD in AOD, Screen off FOD, DT2W on AOD & AOD Clock time update won't work when device in idle(deep sleep). This is done by purposefully.

* RUI 2.0 fw base has some issues with camera. It's totally random (sometimes camera won't open, just wait sometime, it will be fixed automatically). That's why face unlock also not working sometimes(it's using front camera). 

* Don't report bugs without proper logs. Otherwise it will be ignored.
