Blackview BV9800 PRO Rugged Beast MAGISK ROOT REQUIRED

[LGZACRO]

Hi everyone,

I have rooted my last few smartphones and was always happy with it. Now I got new Blackview BV9800 PRO and I want to root it with Magisk. but as the phone is new, there is lack of information on the internet, Anyway, I have found some information, but it is not complete and I believe You, smart guys, can help me to root my smartphone

This is the information I got:

How to root it with Magisk :
Download your rom from : viewtopic.php?f=285&t=532354 (you can alternatively extract it with SP Flash Tool and WWR)
Download and install Magisk Manager on your phone : https://github.com/topjohnwu/Magisk/rel ... v7.5.0.apk
Patch the boot image with Magisk Manager
Unlock the bootloader. (Wipe the phone! )
Flash the patched boot image with SP Flash Tool or Fastboot. (ONLY the boot image)
Reinstall Magisk Manager


This is what I did and what happened:

I installed latest Magisk apk from official sources. I opened the app, clicked on "Install Magisk", then via this app I downloaded the zip file, then tried to installed it via Magisk but got an error "Unsupported/Unknown image format".

Any ideas what have I done wrong? Did I have to flash boot image from the ROM, and not the one Magisk downloaded? P.S., the smartphone is new, nothing more then I written above is done to it (no oem unlocking, no usb debugging, etc).

I let Magisk manager patch the original boot.img. After flashing it with fastboot or SP Flash the phone stuck with message that verified boot didn't accept the signature.

Hm... Is there anyone who rooted BV9800 Pro successfuly and could guide us? ?

update fail.

I greet you, I accidentally deleted it when I updated, Nvram. on my phone. BV9800pro. It is possible to provide me with firmware recovered from a similar phone. I also posted on the forum at Blackview but without answer

 

[LGZACRO]

Isn't there a full firmware download on Blackview website available? I thought I've seen it there

Hello
Yesterday during an update, by accident, my equipment, BV9800pro, performed a complete formatting, "Full Format + Dowload", it seems that Nvram has also been rewritten. it is possible to provide us with a solution or file with this data, specific to our equipment. i need a original nvram.bin, and nvram.data, in firmware from Blackview site this its not exist..


if someone wants to help me, I send them a private message with their email address

My phone is not rooted unfortunatelly, if I can help in anyway (if there is a way) I would pull out the files for You.

Do You know how to guaranteed root BV9800 Pro without running into problems?

who guarantees this?
rooting worked for me with that solution given to the PM. I wanted to install AOSP, but I found that the thermal image did not work anymore, there were some problems when previewing the video files from Facebook, and I gave up. from the mistake as I mentioned I format + dowload and delete all important partitions. nvram .bin si nvdata. Nothing works properly, TEE and Google Key are inactive, the thermal image fails, some applications are closed immediately. This is the experience with rooting and installing AOSP on the BV9800Pro

Oh man... Sounds bad... have You emailed blackview after sale support (via email, not forum)? No response from them?

And let's say I only root my BV9800Pro, will I be able to send You the files You need?

I posted in their forum a detailed error report but the moderator deleted my post.
Don't bargain for help by them.

As I mention there's no TWRP available for this phone yet.

I just rooted BV9800 pro yesterday.
You don't need to SP flash tool or others, just need adb and fastboot.
Quick steps:
1. set OEM unlock to allow
2. connect phone to windows
3. use adb to check if connecting. command: adb devices
4. using adb to reboot to bootloader, command: adb reboot bootloader
5. And then the phone will enter fastboot mode ( you could see small string at left bottom corner)
6. use fastboot command to unlock bootloader. command: fastboot flashing unlock
7. If fastboot program is waiting, please check windows device manager, there should be an unknown device, let windows search driver automatically. it needs android interface driver.
8.Using volume up or down to agree unlock.
9. If agree, all data will be disappeared.
10. Install Magisk manger
11. Download stock ROM from blackview forum. it is zip file. Unzip it and copy boot-verified.img to phone.
12. patch boot.img by Magisk manger.
13. Copy patch image file to windows
14. use adb to reboot phone to fastboot mode
15. reflash boot image file. command: fastboot flash boot patched file name (normally, I would put patch image file in the same folder of fastboot)
16. reboot (fastboot reboot) and reinstall Magisk manager

There are many Magisk root steps instruction in internet. You could refer to other steps, they should be clear than mine. I prepared lots of drivers and application. Finally, I only used adb and fastboot to root this phone.

I rooted it exactly like You and it worked perfectly! Thanks for auch detailed rooting guide!

By the way guys, I think we Should open the request for TWRP for BV9800Pro. How do You think?

 

[james35888]

After you unlocked bootloader, it changed to orange state, and it always shows "Your device has been unlocked and can't be trusted..Your device will boot in 5 seconds", it could be resolved by modified LK image.
Refer to
1. https://forum.hovatek.com/thread-31664.html
2. http://bbs.blackview.hk/viewtopic.php?f=286&t=532899 -- included modified LK image

Of course, you could reflash by fastboot, no need to use SP flash tool.

Hi, I'm not rooted (yet) and my BV9800 PRO is having some issues with the loudspeaker, any media like YouTube or Spotify, play audio for a second or two and then just go mute, volume can be high but no audio at all, phone calls last longer but also go mute and have to go back to regular "ear-speaker" to keep listen to the other side. Are this the same problems you refer to? I can't remember if this happened after the OTA update tho. Thank you.
