[FIX] Asus Zenfone 2 Laser ZE550KL Marshmallow update problem, failed to mount /asdf - Zenfone 2 Laser Q&A, Help & Troubleshooting

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.

recovery link is asking need access plzz help

My Asus Zenfone doesn't boot anymore and doesn't even allow me to factory reset it from the bootloader. How to force reset it??

BootLoop - ZE500KL

Hi friends...
First of all, I'm sorry for my bad English.
So, my phone went to bootloop out of nowhere, no updates caused it, no root method either, just all the suddent... Went to bootloop.
Via recovery mode, I erase all user data & cache = Still BootLoop / Did not work.
Downloaded the firmware from the Asus website (concerning my model of the zenfone), also drivers & tools. So via adb installed it 100% = Still BootLoop / Did no work.
So, if anyone could be facing the same issue and solve it somehow, please let me know the way.
I've seen that this problem is a frequently issue in this phones, but, I haven't seen the solution for this Zenfone Laser 2 ZE500KL specifically.
Thanks in advance.
Place your downloaded full firmware in external sd card. Apply update through sd card in stock recovery.
Solved!

Cannot restore system, stuck on bootloop

Hey guys,
i recently bought a OP2 from Ebay which is bricked (Stuck on bootloop). The phone wasn't able to boot into Recovery. Only thing worked was Fastboot. I managed to get stock recovery to work using this Guide (Method 3):
https://forums.oneplus.net/threads/updated-28-06-2016-mega-unbrick-guide-for-a-hard-bricked-oneplus-2.347607/
Unfortunately it still stucks in a bootloop. I tryed flashing serveral Stock-ROM's. Does anyone know a solution to fix this?
ADB Sideload give me this output (everytime at around 94%)

Make sure to update the fastboot/bootloader to the newer 3.0/hydrogenos version as all newer ROMs require this to boot.
How can i do this? I have stock bootloader v. 1.0 installed and not able to flash via fastboot cause the phone is locked. Cannot unlock because i'm not able to turn the phone on.
Then just use the standard Qualcomm flash-mode to restore the phone to factory OxygenOS 3.0.2. The utility and 3.0.2 full OTA zip required can be found in this forum if you search.

Thanks for the information. The OTA zip file do I have already. Sadly I can't find such an utility you are talking about. The only thing I found was a chineese (or I think it's chineese) tool which I already tryed but not worked. This tool just brings the stock recovery v 1.0 to life.
Or do you mean a diffrent tool?
In a similar position to you. Phone was working fine (only received it today and tried to get CM13 on it)
My bootloader is unlocked, but phone will no longer boot up, or go into recovery.
I can get it into FastBoot, but it doesn't show up anymore in ADB devices. When in fastboot, the device shows as "Android Device, Marshall London Bootloader interface"
If I switch the phone off and check Device manager it just shows as unknown device and then windows gives me an error message that its not functioning properly.
I have tried to follow this guide https://forums.oneplus.net/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/
but it won't allow me to update the device driver, even if I turn off signature for drivers.
The only thing I can get to load is Fastboot. I did at one point have a little penguin on the screen, but haven't replicated that again.
Can anyone help? I'm pulling out my hair
Are you sure you didn't just boot it up into fastboot-ish mode? To be able to flash using that tool you mustn't boot up the phone, make sure it's of and hold volume up when connecting the USB cable, this way the phone will enter chinese factory flash mode at which you can flash using the chinese tool. Also the drivers require you to disable driver signature in windows to install since it's not signed.
Got it working in the end. I just ran the application without bothering with the USB driver stuff and it detected the phone. Then flashed the stock rom and it's now booted.
Still can't get CM13 installed, as I get the error 7 in recovery and that's what got me in the mess!

I turned driver signature of and installed drivers succesfully. I run the chineese tool and it finishes succesfully but the phone is still in bootloop. This is frustrating...
Hello do you have find à solution ??

[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",

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 expand...
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.

Bricked Zenfone 3 ZE552KL - This package is for "WW_Phone" device. This is a ""

Bricked Zenfone 3 ZE552KL - This package is for "WW_Phone" device. This is a ""
I'm handling a bricked Zenfone 3 ZE552KL WW model, but I am unable to flash the stock rom back into the device.
For context, this device has never been unlocked, rooted, and always worked under its original factory Android. As told by the owner, he received an OTA update notification last week and confirmed all prompts to initiate the update. As instructed, he plugged the device to its original charger, left the update running and went by with his day doing other stuff. When he returned, the device was completely OFF with 0% battery. We figured the charging cable disconnected due to a bad connector endpoint, and the phone ran out of juice while the update was running!
The result is a bricked Zenfone unable to boot beyond the ASUS logo. It keeps crashing and gets into a boot loop.
I have tried most of the basic tech support I can give him.
I have downloaded a fresh copy of the official ZE522KL firmware from the ASUS website.
I can boot the phone into recovery, which is still the original ASUS recovery. But as I try to flash the firmware, I get this lovely error message:
{
"lightbox_close": "Close",
"lightbox_next": "Next",

ERROR: This package is for "WW_Phone" device. This is a "".
I know for a fact this is a WW_Phone device because when I try to flash the JP firmware, the error message is different.
ERROR: This package is for "JP_Phone" device. This is a "WW_Phone".
Already tried "Wipe data/factory reset" and "Wipe cache partition" from the recovery menu, but that didn't help.
Already tried pushing the firmware via "adb sideload" and placing it in a SD card. Those didn't help either.
I am also willing to flash a community ROM, like LineageOS or Mokee, but I first need to unlock the bootloader. I'm running adb and fastboot from Linux, and I can't find a descent tool to unlock using Linux is proving to be a real pain. Every tool seems to be made for Windows only.
So, I'm resorting to anyone here, hoping anyone could give me a light before we send this phone directly to ASUS tech support, not available in our region (we'll need to ship it to another city).
Anything I can try before that? I'm running out of ideas.
Best regards and thanks in advance for any help.

Flash the latest stock recovery thru fastboot and then flash the latest raw firmware.
Otherwise try launching, not flashing, twrp thru fastboot and then flash any raw firmware with the updater script edited.

Try unlocking your bootloader using the unofficial way located in the Zenfone 3 forum. It should be doable because you only have to boot into your bootloader. You can then flash a custom recovery, such as TWRP, and go in and wipe data, cache + dalvik, and then install a custom ROM. In your case, it looks like the stock recovery can't detect the device model (WW_Phone), so it's most likely that something is wrong with the system partition.

No need. Flash RAW firmware is enough.
Just a quick follow up.
The owner decided to take it a local assist shop. I don't know what method they used, but they managed to reflash the stock firmware back into the device, and it's working fine again.
Thank you all for the tips. If this was my own device, I would be tinkering a lot more. But the owner decided to play safe and pay for repair in some authorized assistence shop.
Best regards all!

thanks i solved by flashing the original stock firmware again
To root your device, start by flashing TWRP, which you can find here. The TWRP .tar file goes in the AP slot of Odin.
Once you have TWRP installed, you should be able to flash Magisk, which you can find here.
how installa TWRP, i have error
this trying to put... twrp-3.7.0_9-0-a20.img
I didn't notice that OEM LOCK is ON.
You must unlock your bootloader to flash custom images.
ok i haveTWPR done
but after reload sisytem ...
this is very strange, for an old phone, I don't understand, I've never had all these problems ...
i m crazy
Did you flash vbmeta as well as TWRP? This might be the right file
I have to try again ,,,, but I still haven't figured out if anyone has been successful in rooting this device ,, I sansumg told everyone to do it
then, then yesterday I reflexed the original stok, now so I first do a TWPR and THEN this file that you are providing me?
yesss done good
now I need more help, I put TPWR then The file repairs vbmeta ,, ...., but it tells me that I don't have root permissions yet
do i have to give up?
Did you get a working twrp? Try booting into recovery (twrp) and then flash Magisk-v25.2.apk. If that works, reboot into system and install Magisk-v25.2.apk as an app. Then start the app and it will tell you whether you have root. If it doesn’t work, I don’t know what to do next. You may need to have the Magisk apk on a usb drive or microSD card for it to be visible in twrp.
the problem is that I put the TWPR gives me an error
vbmeta ,, then I put your tar file (
vbmeta_disabled.tar
2 KB · Views: 1) the phone starts, but in recovery I don't see TWPR the android menu looks normal
from this menu I tried to install the magic, but the installation fails
When you install twrp from Odin, disable automatic reboot from Odin options. Once you see that the flashing is completed, reboot the phone by holding vol- and power for 7 seconds, then immediately hold vol+ and power to boot into recovery. Otherwise twrp will get overwritten with stock recovery and you have to try again.
I am thinking that by reviewing the file (vbmeta_disabled) it overwrites the TWPR that I first put ,, in the revvr mod it always starts me with the classic menu
[email protected]
but every time I install a TWPR I have to insert after the file (vbmeta_disabled) because otherwise the phone always restarts with vbmeta error in download mod
Use 7-zip and add vbmeta.img from the tar above to the twrp tar and flash that
no work,,stay that way
