[mohamedbk]

Hello everyone ,

Today i will show you how i updated my Asus Zenfone 3 Laser ( ZC551KL ) To android O

You can go to ASUS official website to download newer firmware and instruction manual.
Note:

Please make sure the firmware SKU you download is conformed to what on your phone, eg., WW -> WW, CN -> CN, TW -> TW. Incorrect SKU will lead to update failure.
You can not change the SKU from one to another, eg., WW -> TW, and also can not downgrade your firmware, eg., V2.20.40.13 -> V2.19.40.18.
During update process, please charge your phone with AC adaptor or make sure the phone has at least 15% battery life.


Steps for update:
1. Go to "Need Help?" page of ASUS official website http://www.asus.com/support to download ZIP file of firmware.
Note: Double click the ZIP file after downloading is completed. If the content is another intact ZIP file (as shown in red on picture below),
please upzip the file again.
If the content is not an intact ZIP file (as shown in yellow), you do not have to do anything.
Close the ZIP file after check.

2. Connect your phone with PC via micro USB cable, and copy the ZIP file to the root directory of internal storage of phone.

3. Detach micro USB cable from the phone to make the notification for firmware update poped up on status bar.

4. Tap "System Update File Detected..." and follow steps to update firmware.

For some upgraded versions that have great difference, e.g., from Jelly Bean (Android 4.3) to KitKat (Android 4.4),
you may need to upgrade to a "bridge version" in advance to proceed.
Please see picture below for example.

Hi, do you have any luck with updating your rooted zc551kl?

I'm in same situation. Currently on rooted WW_user_30.42.31.1_20170629, with twrp as recovery, and want to switch to the orero, but afraid to stack in bootloop or brick the device...

I don't think there is a root for the Oreo version we need to wait the developers

Yes, I understand that there are no root for zc551kl's orero firmware.

So I actually asking, is it possible to update rooted device to the latest nonrooted firmware with android 8? And if possible, how to do it?

I'm sorry, does this means, that our device doesn't count on recovery while updating, or twrp can handle asuses update packages?

According to the post below it is possible to update from 7.1 root to 8.0 stock:

The rough order of actions:
1. Restore original recovery - Download the original ASUS recovery, put the renamed img file in root and run the command referenced in section 1 in TWRP
2. Remove root - Go to SuperSU and select "full unroot"
3. Install the fallowing stock firmware: UL-Z01B_1-WW-32.40.106.114-user
