it is not working on my VIVO V19.

fastboot bbk unlock_vivo

FAILED (remote: unlock fail)

is there any other solution...?

if none of those cmd or fasboot commands worked, then why dont your try this method. this is my own personal idea to root vivo phones or your vivo v19.
this method doesnt include unlocking the androids bootloader.
this is done by downgrading your android to the lower version with a patched boot image and flashing it in edl mode. you must know and have the skills or knowledge to flash the firmware.
1. You must have a pc or laptop to do so.
then you have to install some flash tools and the appropriate drivers in your pc or laptop. For qualcomm chipsets you have to install qpst or qfil tool and qualcomm hs usb driver 9008 in your pc or laptop. For more and complete information about the tool and the drivers you just have to look it up online. Personally, i used the qfil tool and the qualcomm hs usb driver for my vivo y11 for its chipset is qualcomm.
2. You download the lower version or stock rom for your phone, then extract that file and look for the boot image.
3. Install the magisk app on you phone then look for that boot image and patch it.
4. Now you transfer that patched boot image in your pc or laptop in the directory where you extracted the firmware.
4. Assuming you have installed the qfil tool and the qualcomm hs usb driver on you laptop.
5. Open qfil tool and select the select the flat build option and browse for the prog_emmc_firehose in the extracted firmware. then click on that. Then browse for the patch.xml and the raw.xml and select those.
---note you must have put the patched boot image in the folder where you extracted the firmware----
6.now, turn off your phone. Press the vol+ and the vol- together while inserting the usb cable and once you see the qualcomm hs usb driver 9008 in the qfil tool then your good to go.
7. click on the download button, and it should start flashing the firmware in your phone.
8. Once it is finished, disconnect your phone from the pc.
9. Open your phone, install the magisk app again
10. Open the magisk app and there you will see the magisk is now installed.
now you can install magisk modules.

Hi, Bordz!

Can you prepare a detailed guide for these process?

I try to flash the rom on qfil tool but it gives an error like cant change to sahara edl mod. I used Zadig to force installing hs usb driver for my vivo y11s (snapdragon 460 SM4250, 3/32 android 12) but it doesnt work.

There are 3 mods in this phone:​

1 ...​

-the touchpanel doesnt work here and computer doesnt detect in devmgmt.msc
-there are 2 buttons in this screen recovery and reboot
-ı can enter this screen pressing by volume up while rebooting

2 ... recovery​

-the touchpanel works here and computer doesnt detect phone
-there are 3 option; install software, clear data and check system
-the install software only allow installing software over the internet, there are no option for local upgrade
-the clear data provides clearing data and cache
-the check system is only making you wait for something that I dont know

3 ... fastboot 1 and fastboot 2​

fastboot 1​

-I can enter fastboot typing "reboot fastboot"
-fastboot getvar all command returning "is-userspace:yes"

fastboot 2​

-I can enter here typing "fastboot reboot bootloader"
-fastboot getvar all command returning "is-userspace:no"

in fastboot 1 and fastboot 2, the computer detect as a fastboot device. I tried to change driver to hs usb, also ı did but ı got errors in sahara tool. adb reboot edl command is only restarting the phone. sorry for my English.

So whats your idea?

#The "Download dail sahara fail qsahara fail process fail" error in QFIL tool is usually related to communication issues between the QFIL tool and the Qualcomm device. Here are some specific steps that you can try to fix this error:

1.Check the USB cable: Ensure that you are using a good quality USB cable and it is properly connected to both the Qualcomm device and the computer.

2.Install Qualcomm USB Drivers: Download and install the Qualcomm USB drivers for your device from the official website.

3.Reboot the computer: Try restarting your computer and then launch the QFIL tool again to see if the error is resolved.

4.Try different USB ports: If you are still facing the error, try using a different USB port on your computer.

5.Enable "Emergency Download" mode: Some Qualcomm devices have an "Emergency Download" mode, which can be used to flash the firmware using QFIL tool. To enter this mode, turn off the device, press and hold the Volume Up or Volume Down button, and connect the device to the computer using the USB cable.

6.Use a different firmware file: If none of the above steps work, try using a different firmware file that is compatible with your Qualcomm device.

#And Here are another steps to fix the "Download Fail: Sahara Fail, QSaharaServer Fail, Process Fail" error in QFIL Tool:

Step 1: Make sure that your device is charged and has enough battery life.

Step 2: Ensure that the correct USB drivers are installed for your device on your computer. You can find the drivers on the manufacturer's website or use a third-party tool like Driver Booster to update them.
Step 3: Open QFIL Tool on your computer and connect your device to the computer using a USB cable.

Step 4: Click on the "Flat Build" option in the QFIL tool.

Step 5: In the "Select Programmer" section, select the appropriate programmer file for your device.

Thank you for your answer .

I tried that you've said.
Disabling driver signature enforcement, install the right driver for qpts, check cable, battery percentage and all of others that you typed.

I think there is a communication problem between my phone and qfil. My phone is y11(s) and there is no way to access edl mode. Vivo is blocking to enter download mode.

why don't you try to manually activate edl mode by shorting the test points on your vivo y11.
Open the back cover of you're phone and unplug its battery, locate the test points. Short it using tweezers while inserting the usb cable and its should show the qualcomm hs usb driver in the device manager in your pc.

My phone isn't y11, it's Y11s. But that's a nice idea I'll try to find these pin if there is, and I'll try to force edl mode. Thanks

let me know, if you have figure that out.

Vivo made it even harder for y85 to be unlocked since OTA PD1730-yd-b_a_5.13.18..

You can't even connect to qcom port, if you try to by pressing vol-up+vol-down&connecting a usb cable the bootloader will be triggered to boot into their fastboot screen. So there's no way you can use emmcdl here.
But I haven't tried downgrading by forcing a corrupted system restore download (the method that needs wifi to reinstall the system). a corrupted restore is done by forcing the phone to power-off when the restore progress reaches between 90-99%. We accidentally did that a few years ago. I thought the phone was bricked by that but no, instead it boots normally without any FRP screen appearing, even the screen-lock was gone, like getting a new phone out of its box.

如果这些cmd或fasboot命令都不起作用,那么为什么不尝试此方法。这是我个人对 Root vivo 手机或您的 vivo v19 的想法。
此方法不包括解锁安卓引导加载程序。
这是通过使用修补的启动映像将您的 Android 降级到较低版本并在 EDL 模式下刷新它来完成的。您必须知道并具备刷新固件的技能或知识。
1.您必须拥有PC或笔记本电脑才能执行此操作。
然后,您必须在PC或笔记本电脑中安装一些Flash工具和适当的驱动程序。对于高通芯片组,您必须在PC或笔记本电脑中安装qpst或qfil工具和高通hs usb驱动程序9008。有关该工具和驱动程序的更多完整信息,您只需在线查找即可。就个人而言,我使用了qfil工具和高通hs usb驱动程序,用于我的vivo y11,因为它的芯片组是高通。
2.您下载手机的较低版本或库存rom,然后解压缩该文件并查找启动映像。
3.在手机上安装magisk应用程序,然后查找该启动映像并修补它。
4.现在,您将修补的启动映像传输到PC或笔记本电脑中提取固件的目录中。
4.假设您已在笔记本电脑上安装了qfil工具和高通hs usb驱动程序。
5. 打开 qfil 工具并选择选择平面构建选项,然后浏览提取的固件中的prog_emmc_firehose。然后点击那个。然后浏览修补程序.xml和原始修补程序.xml并选择它们。
---请注意,您必须已将修补的启动映像放在提取固件的文件夹中----
6.现在,关闭手机。在插入USB电缆的同时同时按下vol+和vol-,一旦您在qfil工具中看到高通hs usb驱动程序9008,您就可以开始了。
7.单击下载按钮,它应该开始刷新手机中的固件。
8.完成后,断开手机与PC的连接。
9.打开手机,重新安装Magisk应用程序
10. 打开 magisk 应用程序,您将看到 magisk 现已安装。
现在您可以安装 Magisk 模块了。
此方法是“使用带有Magsik修补的启动映像的固件降级”
