You can unlock the bootloader with ADB and the ENG firmware, after the ENG firmware is flashed and after a reboot or two you can swipe down and open the settings, then enable developer options and turn on OEM unlock, then proceed to connect to your computer with adb up and then reboot into fastboot then fastboot OEM unlock. Although you can unlock the bootloader, you can't do anything with it as there is no recovery, no TWRP, and custom ROM for the phone, but there are projects that install a linux based android OS, and one of the two (UBports Ubuntu Mobile) has the ability to run Android apps, (given you have Anbox) so if you could get the UBports built for the v520kl then you can have a rooted phone that can run Android apps. I have not looked into Building the UBports yet, so cant say its a viable option.

Hi,

I'm using this phone overseas and can't uderstand why the the wifi is not working while I'm sure it was working in the US. I've used several Verizon phones overseas before and this is the only phone that has a wifi issue.

Is there any solution to this specefic issue without rooting or installing an alternative rom.

Thanks
[Android Q&A, Help & Troubleshooting] game #1:
Hello!

There is no way to change it at this time. Only hope is someone from US will try to push Verizon to make a firmware update to avoid this limitation.

Thanks.

I absolutely hate this device. He is right. Verizon nor Asus will give support. They both pass the buck onto each other saying they have to cover the warranty for the device. Verizon finally just removed the device from my account and didn't ask for me to return it to them. Very strange. Anyways, the point being is that this device will not stay connected to and network after the 2018 update that installed new radio firmware. The problem being that if you connect to WiFi and then leave WiFi the cellular network/data never comes back unless you reboot the device. Enabling Developer Options and forcing LTE to stay on 24/7 does alleviate the issue for the most part but is not a perfect fix. I desperately wanted to root this device and work on a custom ROM/firmware but there is not enough interest and quite frankly the performance on this device is pretty atrocious. Not to mention horrendous battery life. And to address the WiFi issue you are having, it should work everywhere in the world, the standard is the same. Try to reset network settings and very possibly reset the phone back to factory settings.

hello all!

I have V520KL with unlocked bootloader, magisk root and VZW_V3.4.2 firmware. And today i know how enable Wi-fi in other countries. Guide will be later.

Anyone here interested in knowing the camera capabilities of this device?

I'm looking to get one of these devices to test the camera but wondering if someone can install and run a free test app (from playstore) called : CAMERA2probe. After installing and running it will tell you what the "HARDWARE LEVEL SUPPORT " is. among other things

If anyone knows some of these things already I am curious..

1) Is Camera2API supported out of the box STOCK? In other words, can we shoot RAW with 3rd party apps?

2) Has anyone tried 3rd party Camera/ VIDEO apps?

See..........most likely the stock camera only does very limited bitrate for video recording. This device does 4k video recording but stock apps are usually not very good. There is a great FREE app (playstore) called OPEN CAMERA. You can also shoot RAW with this app and you can set the video recording settings to more than 4 times the quality (bitrate).....for example, in settings you set to camera2api, then set recording resolution to 3840x2160, then set bitrate higher and see if it works..

Thanks in advance.

3) Anyone tried GCAM apks on this? (google camera)

V520KL Wi-Fi FIX.

Short guide.

1. You need be in EDL mode with installed drivers (Qualcomm HS-USB QDloader 9008).

I know 2 ways to do it.

a) Flash V520KL_all_WW_eng_T3.3.15 by AFT and reboot to EDL by adb command (adb reboot edl)

or

b)Use EDL cable.

2. Download and unpack "V520KL MODE 9008 system.zip"

Use QFIL from "V520KL MODE 9008 system".

Settings: Port - you port with QD9008.

Build type: Flat

Programmer: prog_emmc_firehose_8996_ddr.elf

XML: rawprogram_unsparse.xml patch0.xml

Flash phone.

When you see "Download Succeed

Finish Download"

Reboot phone to fastboot (pressing vol- and power keys), select Factory reset.

3. After phone rebooted Wi-Fi should be work.

In "V520KL MODE 9008 system.zip" - boot.img with magisk root. If you need root - install magisk manager after flashing.

In "V520KL MODE 9008 system.zip" - system.img without most Verizon apps. If you need VZW apps, download this system.img .Just unpack file to "V520KL MODE 9008 system" with file replace before flashing.

You should know about risk flash this software. If you bricked you device, it's not my problem.
[Android Q&A, Help & Troubleshooting] poog:
Hi, IDLeon I was curious how you accomplished this specifically:

"I have V520KL with unlocked bootloader, magisk root and VZW_V3.4.2 firmware".

I was successful with flashing ENG firmware , unlocking bootloader, and magisk root but I find ENG firmware is very crippled.

Thanks much in advance.
[Android Q&A, Help & Troubleshooting] IDLeon:

hi, about flashing back stock on V520KL

Hi, there wondering if if you could assist. I tried your method of flashing back to stock : But I am getting

"Invalid sparse file format at header magi "......any idea why?

I did " adb flastboot flash all vzw.raw

I dled the raw fille a few times and even DL a zip and extracted the raw again.....and put it in the same folder as adb

any possible clue as to why I am getting this error?

Thanks for any possible assistance

Thanks! Worked first try.

For those that need to know: This is how to reboot into EDL mode : https://www.youtube.com/watch?v=gZSsMDWyDo8 (only difference is, there won't be any indicator lights during edl mode on the V520KL)

I've done this just to have root with stock firmware (not for the wifi solution)...I'm sure many can use this for that.
