Hello members,
i'm stuck in difficult situation.. i tried to flash VIVO Y83 (MT6765) (android 8.1) with STOCK ROM using (miracle thunder & SP Flash tool). I succeeded flashing stock rom (downgrading). i was happy but when i switched on my phone, display was black (it has white screen or shaky and distorted color display where i can see welcome screen, it was untill i flashed it with stock firmware, but as soon as i flash it with updated version of stock rom, the screen goes totally black)..

i also searched internet.. i learn about no rollback feature(no downgrade possible, might be the reason idk) , lockedbootloader (but, i unlocked the bootloader using miracle thunder, when i flashed it for the first time with stock rom) .. etc....
After turning the device ON, it was stuck on welcome screen with shaky display (or black screen with different version of stock rom) and it doesn't turn OFF even after pressing the power button for sometime or boot in fastboot mode, i can click screenshot( i hear the sound of camera clicking) or adjust volume by using volume buttons and power button... i switch off my device manually by removing battery..

One more thing.. i can flash the phone with spflash tool but with miracle thunder it shows "error0_0" while flashing.. I also came to know that when i tried to write perloader from stock rom using miracle thunder it says "BADFILE.. does not write to phone" so, i tried to read the preloader file from the device and save it.. and use it to write and i got no error.. but phone was still stuck on BLACK SCREEN..

CAN ANYONE HELP ME FIX IT... or Any Suggestions ? ...
[i can also provide logs of miracle thunder(let me know that)..]
i also want to know that Is the problem cuz of the da file because i used a da and auth file from a thread post saying, "special da and auth for MTK devices like y83, y81, e.t.c..
i can only flash with these special da and auth file, cuz the da file from sp flash tool(tried different versions) or miracle thunder or from stock rom doesn't work ( i got brom errors)..

P.S.- I have no old or previous backup & it's a secure boot mediatek device...

It’s an incompatible lk.bin issue. Refer to
Did you take note of the phone’s build no. before flashing the phone?
Can you get access to a working Vivo Y83?

Firstly, thanks for replying.. @innagee
how do i fix ik.bin file? (it is named as "ik.img" in stock roms)
Yeah, i found the build number from miracle thunder log file... it's "id:O11019"
Unfortunately, due to covid-19 pandemic, i can't get an access to a working vivoY83
P.S.: i updated the problem with new observations of mine

build number for vivo will look something like this "*****_EX_A_1.11.14" or similar
if you can't find it then you'll need to look for a different firmware build to try flashing, first confirm the build number from the two firmware's you already tried flashing so you don't go downloading them again
also confirm properly that your device is y83 not y83 pro

Vivo_Y83_PD1803BF_MT6762_EX_A_1.11.14_10052018
Vivo_Y83_PD1803BF_MT6765_EX_A_1.13.2_24052018
Vivo_Y83_PD1803BF_MT6765_EX_A_1.20.5_16112019

i tried flashing all three of these stock roms available but it doesn't work for me...
it is VIVO Y83 not the Y83pro

i remember that my phone build number before flashing any rom was either "PD1803BF_EX_A_1.20.5_vivo_mtk_alps-release-o1.mp6-pre4_mt6762" or "PD1803BF_EX_A_1.19.2_vivo_mtk_alps-release-o1.mp6-pre4_mt6762" ... i'm 100% sure because i matched the build number "PD1803BF" to download roms from vivofirmware.com

it does sound like you are sure which build your device had previously. try searching for that 1.19.2 firmware build and try flashing it

I don't have my device yet, I had given it for screen repair (the cause of black screen issue, It was hardware issue)
I tried flashing it with v1.17.6 and this happened -

As soon as I get my device back, I'll try to flash it with v1.19.2 and let you know
