[FIX] Asus Zenfone 2 Laser ZE550KL Marshmallow update problem, failed to mount /asdf

I have good experience with other phones but this is my first time working with ZE550KL.
So I took my uncle's phone and he asked me to update his phone to the latest firmware to get the VoLTE feature.
He is was on ZE550KL_WW_21.40.1220.1708 which is Marshmallow of the ZEN UI.
I have downloaded the latest firmware from the ASUS website but I couldn't update it because the recovery which came with the marshmallow update is broken.
These are the errors I got

}
Here is what I did, and hope this works for everyone.
Hoping that you already went and searched about the problem over the internet.
These are the things you need to download :
ADB and fastboot
https://drive.google.com/file/d/0B0aDjdU4gTwZZW1HUHhqWnEteXM/view
Recovery image file
https://drive.google.com/open?id=0B0aDjdU4gTwZa1MyUmVPN3BhQjQ
Latest firmware:
https://www.asus.com/in/support/Download/39/1/0/22/ZROQURlyupei1ZQz/32/
1. Download the adb and fastboot drivers. Download the latest firmware and copy it onto your internal storage.
2. Boot into the bootloader.
3. Download the recovery image and paste it into the adb folder.
4. Now type the following command.
Code:
fastboot flash recovery recovery.img
5. This step is very important.
Now, all you have to do is hold the power button and the volume down button to boot into the installed recovery.
Remember that if you restart your phone after step 4, your old recovery(which does not work) will still be there.
6. Now select update from sdcard and select the zip file of the latest firmware you downloaded.
7. It will take at least 10 minutes to install, don't panic if you think the screen froze.
I hope this solves the issues many users are facing.
Feel free to ask questions, I will be very happy to answer.
The recovery we installed is the recovery of Android Lollipop version of the Zen UI ROM.

Thanks. It worked. The only difference is that after flashing the old recovery, my SD card was showing blank. So i selected the adb sideload option and flashed the new build.. Thanks for your guide.

Thanks but few doubts remain. The recovery you used is from Lollipop`s 1.17.40.1503 right?
Can we not do this by installing a temporary recovery image (twrp)?
I have also read elsewhere ( https://devs-lab.com/e-unable-to-mount-asdf-recovery-error-solved.html ) that you would need the boot image too. But your instructions are way too easier and easy to follow. Why don't you use boot image?
If we are using the boot image then which version of it should we use?

Before I tried any of this... First thing I did was boot TWRP and install the lastest firmware.
But I couldn't do so because TWRP doesn't let you flash .img files.
And for the best result it is always better for you to use the official recovery to flash an official firmware.
Because ASUS f***ed up, I needed to install the previous version of the recovery to flash the firmware.
And I'm very happy that my guide worked for you.
Don't forget to give thanks. :laugh:

I haven't tried it yet. So you didn't tamper with boot.img at all. Right?
Also as previously asked what's the build number from which you extracted the recovery.img? Is it from .1503?
My current build is .1708 same as what you worked on. And will data get erased during this process?

How can I boot into the bootloader? is it by unlocking it? or is there any other non-invasive way?
Update: I installed as per your instructions. Device shows "Optimizing app 5 of 51".
Thank you.

Thank you
Thank you sir, this helped me a lot.

You have solution for revive your phone then why are you daring ? Anyway if you are satisfied with stock then don't do unlocking.

I am not satisfied with stock rom... And you are right about unlocking but I will do it when I get another phone...

Your bootloader is unlocked if it showing true
Now flash twrp 2.8.7.0 through fastboot
fastboot -i 0x1ebf flash recovery twrp 2.8.7.0.img
When done
Disconnect phone
Remove battery & insert again after 1 minute
Press and hold volume+ , volume- & power key
When yu logo appears hold volume + & volume -
For few seconds. Twrp logo appears and you got twrp installed successfully.

[Q] Bricked - after TWRP restore - unsuccessful

It is the same problem as written here : https://forum.xda-developers.com/p8...awei-p8-lite-2017-pra-lx1-brick-trwp-t3660664
I've followed every steps, but my phone is still bricked.
My build version is (I guess?) PRA-LX1C432B100
I tried several firmware builds to restore on, but when I try to install it (by pushing POWER / VOL - / VOL +) :
- PRA-LX1C530B130 : firmware versions mismatch
- PRA-LX1C33xxxx : can't install, I don't remember error message but surely the same as the above one.
- PRA-LX1C432B128 : "Installing update" at 5% then "Software install failed" with sub message "Get help from http://www.emui.com/emotiondownload?mod=restore"
I followed the rooting method from a french website that was for build PRA-LX1C432B100 but I can't find this firmware anywhere.
Can someone have the link ? Tried with Firmware Finder.. Now i'm downloading from needrom but still don't know if it's for the good build version...
When the phone boots, it displays :
- HW Logo
- Warning about the BL
- HW logo
- blank
- HW logo
- Warning about the BL
- erestore
When trying to download and reboot from erestore, it says "Getting package info failed" and thus, can't download.
----
TWRP
I also tried to flash PRA-LX1C530B130 update.zip, but I get the exact same thing as here : https://forum.xda-developers.com/attachment.php?attachmentid=4008385&d=1484772172

Any way to unbrick this d*mn thing ?
I need help, thank you.

Your phone is locked. Try the unlocking by huawei unlockcode.

Thank you for this fast answer,
though, where do I enter the code(s) ?
I went to https://tools.texby.com/unlock-codes/huawei/ to obtain my code, is that correct ?
I entered fastboot, no devices found with "huawei code writer"
Same with recovery mode and eRecovery :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}

Do this command in fastbootmode by adb:
fastboot oem unlock 1234567...... (your unlock code from Huawei.

Oh okay, but i'm already unlocked.
...
FAILED (remote: already fastboot unlocked)
finished. total time: 0.004s

Click to collapse

Ok., then flash the stock recovery again and make a factoryreset.

I can't find the stock recovery on internet nor on Firmware Finder. Do you know where I can find PRA-LX1C432B100 ?
I flashed many times on differents build versions those files :
recovery.img
boot.img
system.img
cust.img
Do I need to only flash the stock recovery (if I can find it..) to make everything else work ?
if I have no stock system nor stock boot, will it boot ?
And by "stock" I mean "stock for my device" because I've tried many stock images that end up in erecovery, even after a factory reset in the stock recovery.
-- EDIT --
With the mobile app, it says that the PRA-LX1C432B100 has been removed from the server.

Flash TWRP and see if it starts there.

Go TWRP and I can boot. I can indeed see my build version which is PRA-LX1C432B164.
I can boot, so i'm gonna follow the tutorial again.

With B03 I followed this tutorial

But I also tried this tuto since I installed nougat

What is the difference of these 2 tutos ?
Which is best to follow

Seem to be the same. But it easy to use the manual way.
adb reboot fastboot
fastboot flash recovery twrp.img
Or simply use the axon7 toolkit

That way only works if you actually have the bootloader mode, and if you updated to B01 you most probably don't even have it. axon7tool works perfectly if you manage to make it detect the phone.

I guess he unlocked the phone on nougat as I did. So he should have fastboot mode available. So the kit should work. Otherwise you are right. axon7tool.exe is the best way.

If you have root you can use the official TWRP app to flash it from Android.

I tried your manual method but after rebooting, the phone just boots to normal system. There is no menu or anything that signals fast boot.
Then when I used the flash cmd you said above, I get "waiting for device" for hours.
I never installed TWRP on this phone or unlocked or rooted it. It's B32 update.
Do you know any other way?
Axon toolkit doesn't even show up. I also downloaded axon7tool-1.5 but it's the same, no show.
What am I doing wrong? I just want to install resurrection remix on my phone.

I have problem with recovery. Help please !

Hi. First i want to say is sorry for my bad english.
I unlocked the bootloader of my g6 and i have flashed Twrp recovery, but when i try to go to recovery mode i have this messege : " your device cannot be checked for corruption . please lock the bootloader ".
Can anyone tell me how to resolve this because i want to flash custom roms but i cant because i cant go to recovery mode..
Help me please.
Sorry if there was a topic like this, but i can not find a solution to this problem.
Now i see when i go to ADB folder and write the command " adb reboot recovery " after the reboot it says " No Command " and i cant do nothing .. I cant flash.

If you mean this screen ^ that is a normal screen that appears, with every power up / restart, after the bootloader has been unlocked.
I think of it as a "red badge of courage".
As to the question about adb commands, what is it that you are trying to accomplish?

Some more information is needed to help you.
What is your model (h870, us997)?
Are you sure you properly installed twrp (reboot to bootloader, fastboot flash recovery twrp.img)?
Which version of twrp did you use (official, Melina, eliminater's (recommended))?
Regarding your adb problem - do you fail to reboot to recovery using adb from within? Have you tried to turn it off and on again?? I mean, turn it off and try the button combination to enter recovery (turn on holding vol- and power, when logo appears, release power and quickly press again and keep holding both until "factory reset", confirm twice).
Information is key!
PS as the previous poster wrote - if you unlock your bootloader you get the warning screen, just ignore it.

the "your device cannot be checked for corruption" screen is normal, it happens when you unlock the bootloader, no issue there, in order to install TWRP you must:
1. plug your phone in and type 'adb reboot-bootloader' to boot into fastboot mode
2. flash the twrp image via 'fastboot flash recovery TWRPIMAGENAME.img'
3. This is important!: type 'fastboot reboot' and hold the rear button and volume down during the shutdown!, when the LG logo shows up quickly release JUST the rear button and press/hold it again, you should see a factory reset prompt screen, press yes both times, and you should be dumped into TWRP, at this point you can reboot from within TWRP and you should be fine.
Explanation:
the stock LG rom with overwrite the recovery if it determines it has been changed, by booting to TWRP before booting the ROM, TWRP will modify the ROM to stop it from overwriting the recovery allowing TWRP to stay after booting.
I hope this helps

THANK YOU SO MUCH .. It works .. The problem was in the buttons.

I have another problem.. When i try to go to recovery..the only what i see is the logo of TWRP and then the phone just reboot and i cant do nothing.. The phone is h870. What i have to do to have normal TWRP because i want to root it..

Try another twrp version. For Oreo afaik only Melina and Eliminater (which is a continuation of Melina) work. I recommend Eliminater's version, it's up to date (v3.2.3) and backup works - at least for me. I'm on H870 Oreo 20b.
For Nougat I have no experience, as I got my phone recently and never downgraded. But as I understand it from others' experiences, for full custom ROM functionality (e.g. fingerprint) Nougat bootloader is preferable. Search the forum, the information is there!

Yes, I use Melina TWRP, flash Version rel_o2 (or latest) using the method I said above.

Where i can find those versions of Twrp ( melina, eliminater ) ?
