[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Jinx650:
Hi,i have samsung A205F/DS

Security patch level:1 december 2020

Baseband version:A205DDS9BTL1

my bootloader is locked and i want to install custom recovery.Can anybody help me?

I know all basic instructions about installing gsi but not about recoveries.

Official orange fox recovery is available for my phone but i dont know how to install it.

I also read forums on how to install twrp but i am confused that which file i have to flash using odin and whether or not it will brick my phone.

Please tell me how to unlock the bootloader and which twrp file i have to flash according to my security patch and baseband version.
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] sercari:
Hello,

This video is step by step, the procedure applies to the A20 but obviously using the corresponding software for the A20
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Jinx650:
Bro i dont even have twrp installed like your A51
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] sercari:
Excuse me, see it from the beginning, as I said, the method applies to A20
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] Jinx650:
Ok now i just need twrp file for my december security patch but in your video of unlocking bootloader you didn't used any software in pc did you?
[Samsung Galaxy A20 ROMs, Kernels, Recoveries, & Ot] sercari:
Exactly, you just have to enable the developer options and there turn on debugging and OEM and and wait until the oem letters turn gray.

AICP recovery: link HERE

--------------------------------------------------------------------------------------------------------------

New build guys :)

10.04.2021 UPDATE​

Download aicp_instantnoodlep_r-16.1-WEEKLY-20210410.zip from HERE

Changelog: link HERE

No GAPPS in the ROM.zip.

** İf you are comming from older version - no need to flash clean.

-- if you are rooted: Just go to Updater in AicpExtras choose the downloaded zip from your storage and install the update.

-- if you aren't rooted:

**** Download the zip. Connect your phone to your PC. and run adb root in terminal (or cmd windows for Win). Then run adb shell setenforce 0 and install downloaded zip as local upgrade from Updater in AicpExtras. You'll be on enforcing selinux mode after reboot

-- You can flash in recovery via adb sideload. İf you choose this way, don't forget to reboot to recovery and flash your GAPPS.zip via adb sideload again.

-- if you want to clean flash:

**** reboot to recovery. Format data then follow the procedure given below:

flash rom.zip via adb sideload -> reboot recovery -> flash gapps.zip via adb sideload -> reboot to system

What's new:

1. April '21 ASB merged

2. Added ALipay fingerprint payment support

3. Screenbrightness fixes for all 3 devices

4. Many fixes including SafetyNet (fixed again)

Enjoy !!!

--------------------------------------------------------------------------------------------------------------

04.04.2021 Update !!!​

Download aicp_instantnoodlep_r-16.1-WEEKLY-20210404.zip from HERE.

Changelog: link HERE.

-- There is no GAPPS in the ROM.zip.​

Download GAPPS from:

MindTheGapps or OpenGapps Android 11 Nano​

How to install:

1. Go to recovery. Format data if you want to flash clean.

2. Apply Update from ADB

3. then adb sideload aicp_instantnoodlep_r-16.1-WEEKLY-20210404.zip

4. Reboot to recovery

5. Flash Gapps via adb sideload GAPPS.zip

** İmportant: Android Auto fails to connect with OpenGapps. All good with MindTheGapps

** There is no DevicePersonalization app in these - if you want, I can provide a modified GAPPS package

6. If you want to switch in between GAPPS packages, just flash other GAPPS package on the new flash. Clean flash isn't trivial, but recommended....

*** Next flashes can go through Updater or adb sideload.

** If you flash via Updater, backup tool will handle your gapps - no need to reflash them again.

** GAPPS need to be flashed on every update if you flash via adb sideload. Flash them as it is described above.

What's new?

** Stock vibration patterns are back

** App Lock from AOSP-A

** Neutrino Kernel updated to 4.19.183

** and many more....

All feedbacks are appreciated, as always.

** boot to recovery

** flash via adb sideload magisk.zip:

** reboot.

** Note that you HAVE to do this on every update.

** Safety Net is fixed on March 1 build !!!

Nice work.. If coming from another custom rom, oos reflash on both slots is needed or not ?

Any bt calls or sound issues ? thanks

This is my daily driver. So I'm using this device at car wiith Android Auto, with headphones and normally - receiving calls whole.day.

No issues that I can report.

But every feedback is really appreciated...

Regarding having OOS on both slots: While you are on stock, flashing via System Update whole ROM twice is always good ... But we are building vendor too, so you'll be safe in any case I guess...

[OnePlus 8 Pro  ROMs, Kernels, Recoveries, & Other ] marko94:
Hi all,

I flashed this rom, without issuesy. Just follow instructions which dev posted. For root you should sideload magisk zip, older method of patching etc is not sucessfull. Only issue with magisk safety net fails atm. But this is first official build, so we need to be patient.

First thing when phone booted, update google playstore and all apps.

Also enable 120 Hz, otherwise you will think that rom lags as hell :P (settings -> additional device settings ->screen refresh , switch off auto refresh, turn on just force).

About features, hm.. lot of them. If you ever used AICP you know what is there. Also there are some new , especially most intuitive for me "On-The-Go" . If someone is curious about something special, I can post screenshoot.

No big issues or bugs for now.

Swipe corners for google assistant are disabled by default ( not a bug)

Sound in calls via BT working great,without bt also.

Camera works fine, default and Gcam :)

That is it for now :) Great work here @semdoc

[OnePlus 8 Pro  ROMs, Kernels, Recoveries, & Other ] scott45333:
Only issue I have found so far is when I'm playing mad skills motocross 2. The game will freeze for a second or 2, the start working again then repeat. I have tried on stock, hasty and radioactive kernels. Enabled game mode and done everything I can think of. The problem persists. Other than that one issue, the rom is absolutely amazing.

Hello, thanks for your hard work and efforts, for the wonderful firmware

I am writing for your latest Nusantara 2.8 for Realme RMX 2001, after installation, the phone boots up and welcomes the Google setting, and the phone does not respond to touches, and does not even turn off, I cannot go back to recovery. no complaints - the phone hangs on the initial setup screen and pressing the shutdown button, it does not turn off at all, tell me how to enter the recovery using ADB commands, if the phone's sensor does not respond at all when pressed, it does not even have "debugging on usb" ... what to do?
