Is it even possible to unbrick a locked bootloader Redmi note 5 pro in 2020?

[binarygod1299]

i have literally searched everywhere and tried the methods but to no avail. There are some old methods but they dont work anymore.
i cant access recovery but i can access fastboot but since my bootloader is locked, i guess thats no use.

1. Official flash wont work because not a authorised mi account (if someone have this, please for love of god help a brother out).
2.Tried the famous anti test https://www.youtube.com/watch?v=Pf_pPCGkldI&app=desktop but stuck at "ACK count dont match" and i guess others have this issue too. Do anyone know what this error mean in first place?

service center guys is waiting to rip off money with new motherboard but there must be someone somewhere who have good knowledge about and tweak something to make it work.

tl;dr: please provide a working unbricking method for RN5pro (working in 2020)

I can't because for this we should enable usb debugging and oem unlock from the settings , but how we can do that if mobile is stuck at mi logo ??

No, you cant do that. You need to set in developler settings first but since the phone is stuck, you can't do it which means you can't unlock bootloader now using miunlock. if this was possible, we wont be whacking brains in edl n stuffs.

source: i have tried it already n didnt work.

neither the anti test rom nor the anti test patch is working now. it used to work before. ppl getting the "ack count dnt match error" or simply other error. maybe xiaomi patched something .

No no, if you get ack error you just need to power cycle the phone (hold power button for 20-30 sec).
Really easy just need to be patient and retry.
Trust me I done it last week on my friends phone.
Just don't give up.. take a break and try it again. I done it in 3rd try. And use patched firehouse file on original MIUI fastboot rom.
Good luck!

I don't know if this help, I unlocked many Xiaomi devices and it usually takes a lot of wait time but I bought a RN5 Pro from second hand and when I tried to unlock it through Mi-Unlock Tool it did it instantly so it looks like Xiaomi don't care anymore for bothering on old devices, just in case you didn't try it previously.
Also it may help some screenshot as possible of your issue from the Mi Flash tool, I always used the Mi Flash tool Pro for unbrick purposes https://xiaomifirmware.com/downloads/miflashpro/ Have present that a device in this state is highly unresponsive so you have to try it a lot of times to get it working again changing always some things around.

Unlocked a Note 3 bricked like that back in the day using the EDL mode with MiFlash. Just a tip, don't know whether that'll work here.

Another tip: Don't buy any more Xiaomi devices.

Yeahh Xiaomi's edl authentication is bullshit.
Locked edl flashing (which they thought was a security measure) but they bundle miui with full of crap and data miners.
