Try unlocking other vivo smartphones, it may be similar to all at a time coz everyine from v9 are updated to funtouch os 9.0 this says a uniformity among all so try to see flashing of other vivo phones and follow the same among ur phone too.

I just unlocked the bootloader on vivo y85a(the china version v9 youth-pd1730)using https://forum.xda-developers.com/general/rooting-roms/how-to-unlock-bootloader-vivo-phones-t3686690
the key is that the prog mbn file:you can't use the file from the firmware.In chinese forum someone said that if you want to flash the firmware to the phone,you should use different prog_emmc_firehose_8953_ddr.mbn.Here is the different file:https://drive.google.com/file/d/1KeWMM22g8x-aTKhjqS-pmW1iY7z6ZAs4/view?usp=sharing

I'm using this guide to unlock the bootloader.But I found noting can do after unlocked the bootloader.
Vivo add some verify in boot and recovery partition.I tried to port a twrp for y85a and flash it to recovery partition,but it cannot boot.Only "fastboot boot"can boot the twrp,and all of the partitions are report error.
i need Twrp or any custom recovery for Vivo V5
(Vivo 1601).
Please Help.
hello guys ,
i tried every method for unlocking boot loader , finally i found one of the easiest method to unlock boot loader .
Step 1. Boot Vivo V9 in to edl mode
Step 2. Use Qualcomm ultimate tool for unlock boot loader ( Software is free but you have to pay for UMT dongle it will cost approximate 35$ to 45$ depends on your country )
Step 3 . After unlocking boot loader grab your os from your emmc using JTAG
Step 4 . Patch boot file with Magisk .
Step 5 . Copy Magisk patch file in to your device and boot the device .
( BBK electronics vivo official website does not have updated fun touch os file , please don't use any online file , Use your own emmc storage os file for patching magisk )

FLASH STOCK ROM HAVING TWRP USING SP FLASH TOOL(OPPO F9 PRO)

I have an oppo f9 pro ,oppo phones after 2016 are not given fastboot binaries means impossible to access fastboot mode,so if i can't access fastboot mode i can't use it to unlock bootloader and hence i can't install cutom recoveries/roms,root phone .,etc. But i found a thread on XDA where someone was asking how to root OPPO f3 plus(qualcomm based,launched in 2017) and there were people telling that they have rooted it succesfully by flashing stock rom using MSM download tool but i think that rom was modified such that when that guy flashed it using msm tool he was able(AND BY ABLE I MEAN TWRP GOT INSTALLED AUTOMATICALLY) to install custom recovery (twrp recovery) just by flashing that stock rom and also the bootloader got unlocked in that process.
But my phone is baed on mediatek so i have to use sp flash tool ,but my question is that is it possible for me to do the same for my OPPO f9 pro,it has no fastboot mode which is the main problem as i can't unlock bootloader which i easily did in my mi phone using fastboot mode ,but since oppo phones don't have that mode ,it means bootloader can't be unlocked by this process ,but is it really possible to get the bootloader unlocked+twrp installed just by flashing stock rom of my device in it using sp flash tool , i don't know a lot but i think that guy just did something like modifying the stock rom in suck a way that flashing it installs the stock rom+twrp+unlocks bootloader
SO, IF ANYONE CAN HELP ME TO DO THAT I WOULD BE REALLY THANKFUL IM STRUGGLING FROMA LOT OF DAYS TO INSTALL CUSTOM RECOVERY AND HENCE DO WHATEVER I CAN WITH IT AND ALSO REGRETTING WHY I BOUGHT AN OPPO PHONE ,
THANK YOU SO MUCH PLZ HELP IF U CAN:

xiaomi mi A3

im trying to install custom rom and i broken the fastboot. my phone go only edl mode. no have fastboot . please somebody help me
