Do you have the linked for Dolby Atmos? Did you also install Viper4a?
[Zenfone 2 Laser General] bdwilk:
I've used V4A and still think Dolby is better. Just install it, open it and enable the bottom three sliders and then turn your speakers down. It gets loud.

[Zenfone 2 Laser General] wzwilliam:
For some reason i don't know the phone now keeps on bootloop in the asus/android white logos quickly as long as i keep holding volume down, so i just can't enter recovery mode. But i still can enter fasboot mode. Does anybody know what it can be?
[Zenfone 2 Laser General] bdwilk:
Pull the battery then try volume down + power button. Or reflash TWRP through fastboot.
[Zenfone 2 Laser General] wzwilliam:
Tried, same result.

Alright, no recovery but fastboot? Did you try to flash TWRP again?
[Zenfone 2 Laser General] wzwilliam:
Exactly, no recovery, but fastboot. I will try.

[Zenfone 2 Laser General] wzwilliam:
Exactly, no recovery, but fastboot. Tried it, still the same. I guess i should note that it's not unlocked.
[Zenfone 2 Laser General] bdwilk:
Yeah that probably should've been noted in your first post. Flash the stock recovery then put stock firmware on your SD card and in recovery use the "update from sdcard" function. It'll work.
[Zenfone 2 Laser General] wzwilliam:
First things first, so i'll bring no more surprises here: what made me not enter recovery mode anymore was the fact that i tried to install through ADB the stock rom version UL-Z00L-WW-1.11.40.229. Before that i had 21.40.1220.1877. Didn't boot, but could enter recovery mode.

Now what i did: i got the boot.img from 21.40 and tried to flash using fastboot with the command:

fastboot flash recovery boot.img

Still the same: bootloop on the white logos (2-3 minutes each boot cycle); if holding vol down quick bootloop (2-3 seconds each cycle); still able to access fastboot. Was the procedure right? What can i be missing?

Edit: last no more surprises - i'm on debian linux.
[Zenfone 2 Laser General] bdwilk:
Just do it like I said. Flash the stock recovery.img. Then put the stock firmware on SDcard. In Stock recovery there's an update from SDcard feature. Use that. I recovered from a similar situation using that.
[Zenfone 2 Laser General] wzwilliam:
Should i get it from some specific place or just google it?

Done, rom successfully applied, wiped data/factory reset, wiped cache. Now the bootloop goes until the asus silver logo (which does sound like a progress). Is there anything else i can do?
[Zenfone 2 Laser General] bdwilk:
Did you apply update (stock firmware) from sdcard? Does the stock recovery work?

Yes and yes.

Hi! I have teh same problem! I just bought the Asus Zenfone 2 Laser ze601kl, it came with the WW_1.12.40.382 SKU version (i cant even find this version on the Asus website!

This is what happened to me:

I try to update my Asus Zenfone 2 Laser (ze601kl), to a recente version of Android, because i'm stuck on a older version of Lollipop.

My system had a SKU WW, so i downloaded the recent version WW (marshmallow) from Asus website, and treid to update, and that gives me an error. But i reboot the phone a it works fine. But still on my old android version.

Then i tried to just update to a more recent version of Lollipop, the process appears to start fine, but then it gives me an error. Now, i tried to reboot and i end up with a endless bootloop.

I tried everithing, update by adb (cant open the file), update by sdcard (E:Error in /sideload/package.zip (Status 1) E: fota_return_code 408), and fastboot boot.img, recovery.img, but on system.img says the file is to big.

I dont have de USB Debbugind activated. Is that a problem?

I dont have important data on the phone, i just want to make it work again.

How do you resolve this? Gearbest send you a new phone? Help me!

[Zenfone 2 Laser General] 24imelqui:
This method is only applicable if you twrp recovery. If you still have stock recovery dowbload firmware from asus website on place a copy on your internal and external storage. Reboot to stock recovery and select apply update in sdcard and find the asus firmware. Also wipe data before updating or you can do it after.
[Zenfone 2 Laser General] pedrofg:
I wasn't able to do this because i doesn't had access to the memory phone.

I tried all that, update by sdcard, update by adb. Nothing has worked.

I found what the problem was and a solution for that, thar i will post next.

---------- Post added at 07:45 PM ---------- Previous post was at 07:44 PM ----------

Hello guys!

Well, i manage to understand my problem and solv it!

I bought my phone from Gearbest, and the problem begins there. Why? Because, regarless my phone is a CN device, it came somehow with a WW sku. You must know that a CN device have system partition smaller than the WW device.

So, when i tried to updated it with a more recent WW system there was no room for that, and the instalation stops with a error message.

After many "Trial and error", i understand what my problem is, and tried to install a CN system version by "fastboot flash" with a system.img with root that i find here: "https://mega.nz/#F!lodnzDhK!H5ChxausDTyko1qGlnF7dw"

To fastboot i used this fastboot tool: "https://drive.google.com/open?id=0B7...kFRMl81b1pWa0k"

Well, that worked, so i now have a phone working. Them i go to Asus website and downloaded the latest CN firmware to my divece, copy it by USB to the internal memory of my device and upgrade it.

So, now i have a phone working with a factory system but with no google apps.

I found this website with google installer: "https://www.digitbin.com/google-installer-apk/" follow the intructions and finaly i have Google play in my phone!

Now everithing works fine!

I hope that my story could help someone with the same problem!

[Zenfone 2 Laser General] kevinhecox99:
HELPPPP

sir can i ask you how did you do it?
[Zenfone 2 Laser General] 24imelqui:
Try this:

1. Download the latest firmware for your device and and download back2stock.zip package.

2. Open the back2stock.zip(dont extract it; just clicked it 2 times), a window will pop-up if you use winrar

3. Extract the downloaded firmware and select boot.img, system.new.dat, system.patch.dat, system.transfer.list, file_contexts and copy/drag to back2stock window

And wait for it to finish. Wipe everything except internal & external storage, flash the zip and do a factory reset after. Reboot to system, be patient, I think it will reboot a couple of times during optimizing.

Make sure to download the exact firmware, I think there are 3: WW, CN and TN?

[Zenfone 2 Laser General] kevinhecox99:
So currently, I'm back at RR 7.1.2 already since everything I did with the original ROM didn't go well

It rebooted for like, 67 times until my phone ran out of battery (80% before)

I decided to plug in while on twrp and sideload RR 7.1.2 back

hmmm

as far as i can tell, putting the boot.img back into the back2stock.zip doesn't work since it recognized there was no OS

I did all the steps you told me, I have a Z00UD (yes i downloaded the correct version i upgraded manually before to reinstall on this phone)

I did factory reset, even try to format the whole storage and flash each file individually and manually

Just a note to explain how I got this working on my ZE601KL.

I followed the instructions on the 1st page and flashed the back2stock.zip with the image version the phone originally came with.

This resulted with a bootloop, getting to the language selection page and rebooting.

Booted back to TWRP and wiped cache, dalvik, internal. tried to boot but no OS.

I re-flashed the same back2stock.zip as TWRP but still got the bootloop.

On the second install TWRP was over written with the stock recovery. I booted into this and flashed the update file downloaded from the Asus update site.

Phone now booted normally
