Simplest way to access TWRP?

[microlinux]

Hi,

Yesterday I upgraded /e/OS manually using an unofficial ROM. Everything went smoothly. I booted into TWRP and then used adb sideload to install the new ROM.

Now here’s the thing. The shortcut to boot into TWRP on my Samsung SM-A520-F is rather quirky. You have to press down all four buttons on the phone simultaneously, and once the screen goes black, you have to release the lower volume button. At least that’s what I figured out.

Now I have to perform the same operation on my dad’s phone. He lives 1500 kilometers away, so I have to connect to his computer remotely (I’m doing this all the time though).

Here’s my question. Is there a different way to access TWRP ? Can I directly boot into it using an adb command ? This would spare my dad (who’s definitely not a phone hacker) the mess and potential disaster of using a not-very-user-friendly key combination.

Thanks & cheers from the sunny South of France,

Niki

I’ll answer this myself, since I just found the solution. A simple adb reboot recovery does the trick.

There is also available within Developer settings, Advanced restart. This adds boot Bootloader and Recover to the power menu.

Hmmm. I can’t seem to find this option in my Developer Settings. But as long as adb reboot recovery does the trick, it’s not really a problem.

It’s here: Settings > System > Buttons > Power menu > Advanced restart

I don’t have that setting.

In android R 11 :

→ settings → system → advanced → gesture

@microlinux

is there any way to simply update to the unofficial build from within /e/OS without using ADB ?

yes,

1. copy the zip to a SDcard or in the phone “internal storage”,
2. boot the phone into recovery mode
3. then depend of the recovery manager installed on the device :

• TWRP : use the install feature navigate to where the file is stored
  SDcard is located at /external_sd, when “internal storage” is located to /sdcard
• recovery-e → apply update → choose from sdcard1 or → choose from internal storage
  on some models the recovery-e don’t have this feature in this case, replace it with TWRP

Here is the summary : (1) install the appropriate Flashing Tools (2) allow “Non Vendor OS” to be installed on the device (3) Check the communication between the PC and your smartphone (4) Download a custom recovery manager (5) Download an /e/OS build (6) Unlock the Bootloader (7) Flash a custom recovery manager on your device (8) install /e/ from your computer, using the “adb sideload” method or (9) Install /e/ without computer using the “Device-Storage…

And, of course, Settings has a Search function, useful if the setting is in different places for different devices / builds.
