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 installed TWRP using flashify with no issues.. You might want to try that.

Which version TWRP are you using? Are you on kitkat? Trying to root and install TWRP

I am a newbie here. But I unlocked my device thru the carrier. What have you been able to use to unlocked boot loader? I have Lollipop 5.02 running on my device.

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.

Bricked boot.img, but got Stock Recovery

Hello everyone!
So, after I replaced my SM-G935v with SM-G935FD I decided to root it, but accidentally installed a wrong boot.img using ODIN.
I can not access the comforting Download Mode with three-buttons to re-flash to the correct boot.img file, but I can access the Stock Recovery, and it can flash ZIP from ADB and SD.
I'm currently downloading ROM files for my S7 Edge to flash them using ODIN, but since I've only got access to Recovery, could some of expertise help me on what the hell I should do?
I'm looking for a way to make a flashable ZIP out of the boot.img I'm downloading, but I can't find anything. Is this a good plan, and if it is, how can I achieve it?
Should I proceed to make a USB Jig?
Can I do something like this?
Code:
fastboot flash boot boot.img
I've just bought this phone for eight hours, and I unfortunately can't return it to the seller!
This is what I get when I try the three-button combo:

TWRP can flash img............, but I don't think stock recovery can do it..... because you need find a signed kernel and ram disk....... and there is no fastboot in samsung phone.... you should try kies..... maybe it can save you.... and idk about JIG

P9 Lite bricked

Hello,
I was on B336 and wanted to root it. All good, I followed the steps, and accidentally wiped cache&dalvik... Bootloop. Then I tried to downgrade to MM... No success... After that, something told me to wipe system, data, Dalvik, cache, everything except for Internal Storage, phone storage... I tried then to flash EMUI 5 beta 336... It didn't work. I tried then to flash Meticulus TWRP instead of Revolution TWRP... It did not work... I tried to dload MM stock, it did not work...
I'm stuck with:
-No OS
-Revolution TWRP
-Meticulus TWRP doesn't boot
Is there anything I can try to get it booting or I can throw the phone into the garbage bin?

I even tried to flash Meticulus TWRP with the RevolutionRecovery (I know, I know) and of course it did not work...

If you are with no OS
flash via fastboot system.img boot.img cust.img and recovery.img using app extractor
I don't remember the exact order (yes, you must flash them in a specific order)

Found the order:
- Fastboot flash boot boot.img
- Fastboot flash system system.img
- Fastboot flash cust cust.img
But I can't understand the part about app extractor. Can you explain please?

There is an app called app extractor (you can easily find here in the forums)
You put your Update.app file (the one you should put on the dload folder) and the app extract you these files
After you flash them via adb
I had your problem and solved using this
(Sorry for my english)

@diorenzo Ok, I got it, I extract from the .APP file with Huawei Update Extractor. What should I do next?

Go on fastboot mode with the phone
And via pc flash the files

Tried two times with no success... I'll try switching ports.

Sounds similar to what I had. Take a look here.
The solution in brief was:
1. Go into bootloader to flash recovery (I used Revolution Recovery)
2. In recovery, flash OEM info.
3. Then used the 3-button method to install stock version for the appropriate model (which I could see from OEM info).
4. Unlocked bootloader, triggering a factory reset. (I was stuck in infinite boot before this point.)

It was what i was thinking
I though he could flash recovery via fastboot (but i didn't remember he had to flash oeminfo)

[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.

recovery link is asking need access plzz help
