How to update UN1CA

[salvogiangri]

Updating UN1CA is an easy and straightforward process, if you did follow the first time install guide correctly, simply downloading and flashing the new update without any extra steps is enough. If you're wondering whether or not you need to format again your data to update to a newer version:

• You can't dirty flash if you're coming from another OS (eg. AOSP, another One UI ROM such as stock)
• You can dirty flash if coming from an older 2.x.x build (eg. 2.1.5 → 2.5.0)
• Dirty flash from an older 1.x.x build (eg. 1.1.6 → 2.5.0) might work as long as you flashed an official release, but in this specific case we highly suggested to instead follow the first time install guide to ensure no issues happen

Updating via UN1CA Updates app

Since version 2.5.0, we are providing a new easier way to keep your device up to date by introducing our brand new UN1CA Updates app. It can be accessed via the System/UN1CA Settings and it allows to:

• Receive notifications when a new update is available, the update check frequency can be customized in the Settings → Auto updates check menu
• Download the newly released updates when you want
• Pause and resume the update download as you prefer
• Install the update automatically without user interaction

When a new update is available, follow the steps on the screen to let the app download and install it for you automatically.

Manual update via UN1CA Updates app

The UN1CA Updates app also allows manually installing UN1CA zip packages you have stored in your device, please note this is only possible when trying to install a package which version is 2.5.0 or above. First, enable the app "expert mode" by tapping 7 times the app version number in the "About UN1CA Updates" page in the app settings, this will allow the Local update menu to show up in the app home page. From there, you can select your stored UN1CA zip package, the app will proceed by importing the update and asking you a confirm before installing (see above).

Manual update via recovery

If you still want to update your device "the old way" or you haven't updated yet to 2.5.0, proceed as follows:

• Download the latest available UN1CA zip package for your device

• Reboot your device into recovery mode

  • Rebooting via key combo: power off your device, connect it to your PC via an USB cable and press the recovery mode key combo for your device.

  • Rebooting via Magisk/KernelSU Manager: open the Magisk/KernelSU Manager app and tap the "Reboot to recovery" option in the Toolbar menu.

  • Rebooting via ADB: connect your device to your PC via an USB cable and run the following command:

    adb reboot recovery

• Install the UN1CA zip package

  • Install via recovery UI: Open the Install menu, navigate to the folder where you stored the UN1CA zip package you previously downloaded and flash it.

  • Install via ADB: Open the Sideload menu, connect your device to your PC via an USB cable and run the following command in the directory where you've stored the UN1CA zip package you previously downloaded:

    adb sideload <file>

  Make sure to replace <file> with the name of your UN1CA zip package file (eg. adb sideload UN1CA_2.0.0-07d0046_20240616_a52sxq-sign.zip).

If you followed every step correctly, the ROM has been updated succesfully and you can now either exit recovery mode by tapping Reboot → System, or tap Reboot → Recovery to finalize your setup by flashing a custom kernel or the root solution you prefer.

@salvogiangri Thank you very much for this very detailed guide. Could you also add it to the UN1CA ROM thread on the xda dev forum? 😊

[salvogiangri]

The XDA threads all have a link to the GitHub discussions page of the repo.

[kdejeqq]

Ok thanks sir 😊😊

i have un1ca 2.2.2 s20 fe without root, and in twrp my files seem to be encrypted. is there a way to dirty flash 2.5.0? thanks!

[Hayarare]

You can dirty flash using ADB sideload instead of installing from TWRP.

[gbfllp]

i was afraid of, but it works. ty

That did the trick thanks

Help, please.

[salvogiangri]

Looks like your super partition is damaged. Reflash the stock firmware and try again.

[grillobak]

you may do a complete cleaning or formatting using the TWRP and directly install the 6.1.1? version

Hi, sorry to bother you... How can I install this update?, it takes me to twrp and there I cannot find the downloaded file from UN1CA updates in any of the available folders so I didn't know how to proceed.

[gusthig]

Same here. It downloads, says it's installing then reboots to TWRP and I can't find any sign of the update. I just select reboot to system and the update prompts again.

[GreenMioFa]

Update: I ended up exporting the zip to my pc and just shoved it into my internal storage using ADB on twrp and installed it from there

[naxitoo]

It's due to a recovery issue, if you own the S20 FE, this is the situation:

[gusthig]

It worked! Thanks a lot!

I am now stuck on twrp splash screen and if i reboot manually or with adb i just get back into twrp
edit: ended up having to reinstall both twrp and un1ca

[czerwinski76]

That's a good question. I've always got the same problem.

I've never managed to install a UN1CA update ROM without having to start from scratch with TWRP recovery installation + UN1CA installation + Magisk zip+ partition decryption (FORMAT DATA !!!).
If I didn't do like that UN1CA ROM makes bootloops every time.

Restoring DATA partition with TWRP is not working 😱.
I have lost all of my data 😵.

[jcuaran7]

Encontraron una solución?

[czerwinski76]

No.
I had to install my rom from scratch 😵.

[Melvin-cpu89]

Hi, could you make a video showing how should we update?

[czerwinski76]

None has time to record a video, here is the timeline of how it happens -Update comes and sends you a notification -You click download -It finishes download and asks you to reboot -You accept -It boots twrp -Depending on your twrp you might need to write your pin -Update process starts without any prompt -After it finishes you click reboot to system -You boot into new version

New update boots into TWRP and thats all.
Updating make bootloop on my phone (r8q).

[Melvin-cpu89]

How do i know that it's completed

[utkustnr]

New update boots into TWRP and thats all. Updating make bootloop on my phone (r8q).

You need to update your twrp, 12.1-3 fixed that issue.

How do i know that it's completed

You'll see a "Update finishing..." notification once you boot and your un1ca version in un1ca settings will reflect the version change.

[GreenMioFa]

If you get bootlooped:
-Update comes and sends you a notification
-You click download
-It finishes download and asks you to reboot
-You don't accept
-Tap the 3 dots on the upper right corner
-Select the export zip option (or similar)
-Export to SD card or PC
-Now you either boot into twrp and apply the update from your SD card or you'll need to push the file into an unencrypted folder like /Data using ADB (from a PC)( adb push un1ca. zip /data) and then you navigate twrp and update it from there
-After it finishes you click reboot to system
-You boot into new version (hopefully)
-Check in the settings if it was updated successfully

I think that's what you'd need to do, hopefully it helps

[utkustnr]

I think that's what you'd need to do, hopefully it helps

That's correct. However seamlessness of the ota update depends on the recovery and it's maintainer. Any proper recovery that supports openrecoveryscript will have a seamless experience, close to stock updates. It doesn't even require decryption, just proper openrecoveryscript support.
