Unlocking bootloader/ rebooting in edl without testpoint Vivo Y31 2021
- Thread starter Pervokur
- Start date
ok...I'm sorry that iqoo neo3 is false information.
my iqoo neo 5 lite (pd2118b) current firmware is 6.15.5
Android security update patch time is 2022-04-01.
Full package firmware
6.15.5 - is it A12? even potential bug(no ota firmware files check in recovery, presented in early A12 vivo firmwares before May) should be fixed.. otherwise you could be able to downgrade android just by editing metada file in old ota zip and install it through recovery or factory test apk
It is Android 12, and then it can be downgrade android, but the minimum Android version is 11. However, Android 12 and Android 11 have the same result for unlocking BL.
Did you try one of the first firmwares ? There no message about unlocked BL during booting process on earliest A11 firmware for my phone.
others have tested it. The firmware version is 1.6.6, and the results are the same. I want to give up.
This is a tool from our QQ group.
I think it is necessary to remind those of you who use the sm8250 device that the sm8250 is not applicable to this method.
fingerprint unlocking can also be used normally on x70pro+. You only need to use version 1.5 factory test to calibrate the fingerprint
It's not in my file. It's here.
Next, my expression may be incomprehensible to you because my English is not good. In order to facilitate understanding, I will provide Chinese for your reference
1. You need a black and flesh rubber
2. Installation factory test 1.5
3. Enter phone input * #558# enter factory test
4. Find the quality test
5. Find the fingerprint test
6. Photoelectric fingerprint calibration
7. Use flesh colored rubber for calibration
8. Use black rubber for calibration
Now, you can enjoy root and fingerprints.
Chinese
1.你需要一块黑色和肉色橡皮
2.安装工厂测试1.5
3.进入Phone输入*#558#进入工厂测试
4.找到品质测试
5.找到指纹测试
6.选择第一个光电指纹校准
7.使用肉色橡皮进行校准
8.使用黑色橡皮进行校准

It may not be applicable to vivo, or your operation method may be incorrect.
Dumb questionI did it!
These feature works even after BLU:
Fingerprint sensor
Face ID
OTA install
and Magisk works too!
You have to use DSU Loader to get boot.img though.
Here's full firmware dump of PD2178_A_12.0.14.5.W10 (contains all partitions for research purpose):

Can I use the boot.img here to root?
Bro I tried the termux method on my android emulator but it wont detect my android in fastboot and whenever trying in windows always failed
I can't see any commands and any errors. Mb you should learn how to write informative post

@everyone who unlocked:
Does your camera portrait mode work?
If I take a portrait photo there is no visible bokeh and if I edit the bokeh through gallery moving the slider does nothing.
This might be some bull**** DRM they implemented with BL Unlock.
Edit: Relocked BL and portrait still does not work.

2Unlocked models with this method:
Vivo Y31 PD2050F 2021 A12 6.7.20
Vivo V21e PD2107F A12 6.6.19
I did it from rooted Samsung J120F, I didn't try from PC///bc no PC =(
My guide in Russian {Mod edit: Link removed}
Custom fastboot for vivo in ubu.zip is from here https://xdaforums.com/t/how-to-unlock-bootloader-of-vivo-phones.3686690/
Video of a double terminal attack. After I came up with such an idea, I succeeded on the first try. To reboot in edl just use
fastboot oem reboot-edl
instead of
fastboot vivo_bsp unlock_vivo
REMINDER! Rebooting into edl from fastboot returning locked state, so you should unlock again if you need it.
My setup
rooted Sumsung J120F with A10 custom rom from this forum
custom fastboot for vivo v2 (Linux x86_64) from this forum (for vivo_bsp command)
Termux from f-droid
Ubuntu CLI from here https://github.com/tuanpham-dev/termux-ubuntu
So there is nothing from mother Russia=) Well... only sources list with officials servers with tag arch=amd64, you can create your own in order to download x86_64 libs.
You can use any .img, big enough.
Vivo Y31 <
qemu + fastboot , so i could run x86_64 on my 32 bit arm phone
Ubuntu to run qemu
Termux to run Ubuntu
Magisk to grant root
All commands with root, otherwise fastboot will not see device.
If you can copy-paste commands, then you will understand this
Подготовка
#
1. ставим termux с f-droid
скачиваем кастомный fastboot для виво и источники пакетов для ubuntu Прикрепленный файлubu.zip ( 362.4 КБ )Кол-во скачиваний: 10
и распакуем в обычную стандартную папку Download, она же Загрузки
скачиваем vendor.img , хотя наверное может подойти любой vendor.img или даже любой *.img
2. запускаем termux
3. вводим
termux-setup-storage
соглашаемся
4. вводим
pkg update
на вопросы отвечаем
y
ввод
5 ставим сюда ubuntu, копируем-вставляем всю строчку
pkg install tsu wget curl proot tar -y && wget https://raw.githubusercontent.com/tuanpham-dev/termux-ubuntu/master/ubuntu.sh && chmod +x ubuntu.sh && bash ubuntu.sh nde
соглашаемся на все
задаем пользователя и пароли(пользователь маленькими буквами, пароль минимум 6 знаков!!!), я задал
user
user
mmmmmm
mmmmmm
6 мы внутри ubuntu, но давайте выйдем и зайдем
exit
заходим в убунту с рут
sudo ./start-ubuntu20.sh
7 получаем рут и переходим в корень
su
вводим пароль, который вы задали, у меня mmmmmm
cd
копируем из загрузок файлы фастбут и источники, чтоб можно было скачать x86_64 либы
cp ../sdcard/download/amd64.list ../etc/apt/sources.list.d
cp ../sdcard/download/fastboot ~/
8 добавляем целевую архитектуру x86_64
dpkg --add-architecture amd64
9 все обновляем
apt-get update
10 ставим qemu
apt install qemu-user
11 устанавливаем x86_64 fastboot ради библиотек(может и не надо)
apt install fastboot:amd64
Атака
#
12 В ubuntu запускаем наш фастбут через эмулятор
qemu-x86_64 /root/../lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 --library-path /root/../lib/x86_64-linux-gnu/ ./fastboot --help
жмем стрелочку вверх , стираем --help и вводим vivo_bsp unlock_vivo
выполняем и получаем fail
13 в термуксе свайпаем с левой верхней части экрана для показа меню и жмем new session, это нужно для второго терминала
#
14 выбираем второй инстанс и также заходим в убунту
sudo ./start-ubuntu20.sh
далее
su
вводим пароль, который вы задавали
перходим в корень
cd
теперь можно сразу две команды посылать
15 В новом терминале вставляем
qemu-x86_64 /root/../lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 --library-path /root/../lib/x86_64-linux-gnu/ ./fastboot flash vendor /sdcard/download/vendor.img
файл vendor.img должен быть в загрузках
Пойдет загрузка файла в телефон, но не прошивка. Её без анлока и полного скачивания не будет
16 Переходим в первый терминал и выполняем команду повторно
стрелочка вверх - ввод
qemu-x86_64 /root/../lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 --library-path /root/../lib/x86_64-linux-gnu/ ./fastboot vivo_bsp unlock_vivo2
