New DerpFest A13 Tango Update!

Must Read All Important Instructions Here Before Flash:

* If you're coming from Stock Rom(Realme UI 2.0), you need to unlock your bootloader. Realme UI 2.0 deep testing apk not released yet. So you need downgrade to RUI 1.0 using rollback package for unlock your bootloader. (See #rollbackpackage, #bootloader_unlock, #twrp_guide & #cusrom_flashing_guide notes from Realme XT Telegram Group)

* This ROM based on RUI 2.0 firmware. So Need to flash it over RUI 2.0 firmware(No need to download full firmware, it's just fw only, under 150mb in size). Get it from Realme XT Telegram Group notes (#firmware_download) or Download it from Realme XT Telegram channel.

* RUI 2.0 firmware zip automatically flashes realme UI 2.0 supported TWRP recovery(included in realme UI 2.0 firmware, but it won't support A13 decryption bcoz it's old & not updated)

* So if you want to use latest recoveries(supports A13 decryption & up to date), download & flash it from main group notes or from Realme XT Telegram channel after flashing the firmware.

* Need latest UNOFFICIAL TWRP (OR) OrangeFox (OR) Pitch 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.

* Don't download twrp from twrp official website bcoz it doesn't work on RUI 2.0 Firmware Based Custom Roms(official support dropped long ago & not updated)

* Wipe system, data, cache and dalvik cache. Flash RUI 2.0 firmware first in recovery then reboot to recovery again. Flash Rom zip, do format data by typing yes, Reboot to system. Flash magisk after first boot only if you want to root your device.

* You need to clean flash with format data by typing yes in recovery if you're coming from stock rom, A12, A12.1 or any previous Android versions. It's MANDATORY. So take backup of your internal storage & app data before going to flash.

* If you want to ota updates work on next builds, you need to flash this build using latest recovery with format data mandatory(You need to do format data first time only after flashing latest recovery to ota work properly). Otherwise ota update won't work on recovery.

* Before updating via ota updater remove all lockscreen passwords.

* If ota updater not working(see #ota_not_working) in recovery(bcoz you didn't followed above steps correctly, Probably you didn't formatted data after flashing latest recovery), copy downloaded rom zip(see #ota_location) from root/data/derp_updates(Use any Root file manager bcoz Root needed for accessing this directory or you may access it in recovery). Copy zip file to internal storage then normally dirty flash it in recovery.

* You can dirty flash(see #dirty_flash) it if you're using previous A13 build. Remove all lockscreen passwords before doing dirty flash for safety.

* Clean flash(see #clean_flash) always Recommended! Dirty flash at your own risk. Both clean & dirty flash needs all lockscreen passwords to be removed. Otherwise your data(RIP internal storage) may be encrypted. You need to format data by typing yes to decrypt. If your device bootloops, revert to an older build that boots, backup your stuff and do a clean flash.

* Flash magisk zip & nfc removal zip after every dirty flash (After first boot strongly Recommended!)

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

* If you're using jio sim(india), use VPN to check ota update. (VPN only needed for fetch ota, you can download it without VPN)

* 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 patience.

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

* READ below notes from Realme XT Telegram group for more details.

Known Issues:

* DT2W on AOD won't work(Use fod instead)

* AOD time won't update while charging

* Google backup & restore broken

* Turn off Ripple effect for better fod experience

* Fod won't work on adaptive color mode. So use default(Display --> Colors)

* RUI 2.0 fw base has some issues with camera. It's totally random (sometimes camera won't open & torch light qs tile will say "camera in use" , so just wait 1-2 minutes, 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.
