Hi there, i was able to unlock the bootloader easily and see the white splash screen, however it does not look like i have successfully flash twrp (although the program say successful). How to get to TWRP and what does it look like?

Please help. It appear that i am still on the stock recovery

Just for informational purposes no real need to change name

fastboot flash recovery twrp.img

Will work as well.

Can we lock the bootloader again, as i need to go to service center for rear speaker problem in my phone, i am worried that if they don't repair it under warranty by saying that the bootloader is unlocked
[ZenFone 2 General] fiveman:
You cannot lock it again but you can try reverting it back to black splash screen. Not sure if the Asus people can check it or not. You can update us if Asus did not notice:good::laugh:

Its need open bootloader?

i have ZE551ML and after root, and install the twrp installer, and then install the twrp itself with the app, i'm not able to boot into recovery, and for bonus the device has lost root, so i rooted again with temporary cwm method, but after every reboot its unrooted.
[ZenFone 2 General] alboz83:
Hi, i know is impossible to re-lock the bootloader, but if i unlock and then i need to send my zenfone to Asus assistence for some problems, it would not pass under warranty, right? I would try some custom rom, but i don't want to risk!!

I want to root with Linux and as a first test I am trying simple adb and fasboot commands.

from dmesg:

/etc/udev/rules.d/70-persistent-net.rules contains this line:

SUBSYSTEM=="usb", ATTR{idVendor}=="0b05", ATTR{idProduct}=="5f02", MODE="0600", OWNER="<~/>"

adb devices

fastboot -i 0x0b05 devices

Hey I have a problem using this guide.

1. i have version 2.19.40.18

2. i am rooted and root access is working.

3. adb is working (i used it to sideload updates)

4. this is where i hit a wall. guide say:

adb shell (press enter)

when i do that i get "error: closed" message and nothing happen. i can see my device when i type adb devices, i can use sideload, but cant use shell command.

i tried reinstalling SDK and updating it, but it didnt fix anything. i can't find what is the problem. anyone know how to fix this?

EDIT: ok i downloaded terminal emulator and it said unlock sucessful. thanks!

Dear forum memebers.

Maybe you can help me.

My son bought an Asus Zenfone 2 type ZE550ML during the hollidays.

When we came home he charged the phone from the USB exit of his computer.

After that the phone would not start again do you now what the problem could be?

Is there an other start sequence to start the phone?

I hope one off you can help me because my son is in tears over his phone.

I own a North American version and the new OTA is not available yet.

Is it just a matter of waiting or have they pulled it off their servers?!

have to be the new build (2.19)?

Unless downgrading the rom to an old one that makes unlocking the bootloader possible then upgrade to the latest update afterwards.

If your splash screen is white then your bootlocker is unlocked.

If your splash screen remains black then try Windroid another time.

Which method 3 for linux do you mean exactly?

I've found only 2 methods (for windows), that are specified in this thread.

I supose the reason for this failure is the leak of fastboot support for Intel devices.

I supose that the debian adb and especially fastboot packages are the newest one.

.

Probably you are the first one that gives the right instructions for adjusting the root method for linux users. Thanks
