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 ??

unlock bootloader for v410

I was wondering if there was a way to unlock the bootloader on the v410 running 4.4.2. I have tried FreeGee and my device freezes and then restarts. I am rooted (TowelRoot) and have SuperSU and Busybox installed. I would like to be able to install TWRP recovery.

I have been fighting this for a couple of days. It seems that users are downgrading to a previous version 4 of Android in order to unlock the bootloader. I have been unable to make this work personally. Kingroot rooted 5.0.2, but the TWRP recovery ROM will not load. I think it's because the bootloader is still locked.

Yeah I'm having the same issue. If I flash the e9wifi .IMG recovery then boot recovery I get this fastboot screen which I've never seen on this vk410. I can't really use fast boot commands it seems not to respond well I know something is off I'm curious if its my headspace and timing or the tablets.

Can't install ADB, TWRP, or OS

Guys, I think I messed up big league. I set a pin on startup and I'm guessing that encrypted my "system" partition. After trying and failing to decrypt that with the PIN I had set to use on startup I tried wiping "dalvik", "cache", "system", and "data". Then I flashed DrakenFX's B15 stock ROM, but it's still asking for PIN on startup. When I rebooted, I was faced with the stock recovery. ADB won't install on my computer, so I don't know how to flash recovery back onto the device. (Do I need the device powered on and in an OS for ADB to recognize the device and install the correct drivers?) TWRP says there is no OS installed. So, I guess my question is this: How do I decrypt my device and get back into an OS.
Thanks a million for your help in advance.

The only way to really decrypt your phone is by formating it, as for twrp try fastboot instead of adb is going to be easier and then download the OS of your choice if u need further help pm me ill help u through teamviewer

*EDIT* So the ADB installer ver. 1.4.3 wasn't playing nice with Windows 10. I installed the 1.3.0 installer and it worked right away.
Thanks! I'm back into DrakenFX's B15 ROM, now I need to figure out how to get ADB and fastboot drivers to install correctly. Every time I run the ADB+Fastboot installer, I go through the process and it says "0 Files Copied." Any help there?

This is the adb and fastboot i use:
https://mega.nz/#!FdARiCIJ!QM_sfJ_JNBNv5HvjyNycVVZCSN6fUP5gVZdXKpUOAbo
To use it simply unzip the files then shift and left click and then click "open command window here" if you want to use adb type abd then whatever same thing with fastboot

[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

"lightbox_toggle_sidebar": "Toggle sidebar"
}
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??

Axon 7 not able to install TWRP or lock bootloader

Hello all,
I need help with my Axon 7 (A2017G)
I upgraded my phone to Oreo 8.1 (AospExtended), played with it a bit, but decided to downgrade to 7.1.1 (stock) again.
After I did so, I noticed something different. Firstly when it boots up, this screen appears
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It goes away after 5 seconds and boots or if I click the vol up or down button, it takes me to this screen
If I choose anything other than Recovery, the phone just boots up
If I choose Recovery, it takes me here
I cannot boot into recovery mode at all. I can't find out how to install TWRP recovery on here at all.
Also If i boot using power+vol down, this appears
Please advise how to install TWRP and lock the bootloader

Have you tried the Axon 7 tool by Djkuz?
It should be able to get you out of this, I'll find the link for you.

that is, like, 100% normal. you have stock recovery and that FTM mode just gives you adb. If you can't enter fastboot then you would have to install it via EDL.
But before doing that, why the heck would you want to lock the bootloader? Lol you can just hide the 5 sec screen and sell it (or return to zte, they never check), there's no difference at all
If you're gonna lock anyways, you have to install TWRP via EDL (use EDL Tool by djkuz) then install the "remove inscription" by raystef66 or follow the steps on his guide. Then you will get fastboot. After you do that, just reboot the phone. TWRP should be replaced with stock recovery again. Check if it was (power + vol+) and if you enter stock recovery then go to Fastboot (via "adb reboot bootloader") and do the command to lock
Of course you have to be FULLY stock (no magisk or whatever) or you'll brick your device
