Thank you both.
However I have already been able to unlock the bootloader, :laugh: install twrp and the new 8.11.7 keeping the bootloader unlocked and twrp as it should be, all using same PC and my Mi Account, how I did:
1- Ask the SIM card and authorized account Mi of a friend
2-Factory restore from my F1, I introduced the sim card from the friend, and started the F1 with my friend's account (without the factory restore did not work)
3 - I opened Miunlock on my PC, with my friend's account, and tried to unlock the bootloader, did not allow saying that I had to spend 72 hours after the last bootloader I made, but I was happy because it no longer gave the unknown error -1
4 - I returned the SIM to my friend, and put my SIM, having finished the session of the friend's account and log mine, reboot
5 - I opened the Mi unlocker, I loaded my account, and voilá!! unlocked the bootloader normally.....them twrp, and then flash 8.11.7.zip over twrp
I conclude that when we flash to 8.11.2 by Miflash, and the bootloader has blocked, the Mi unlock was confused and with some error,loging my frind account free of issues, the error has been corrected, so i can re-use my account normally, and unlock bootloader.

Thankyou for your reply brother but it didn't work for me new account showing me to wait 72 hours so, i should probably wait.

Wait 72 hour is ok. My friend already unlocked by using that way.

The exact same situation i have been stuck at!!
XDA truly be the abode of Android.
I wasn't hoping to find this issue with anyone else as such until this moment!
I have been awfully stuck at this 8.11.2 build with a locked bootloader without even being able to update to the later versions!
The mistake was that i carelessly moved on to flash even without noticing the default was set to lock the bootloader.
Things i tried:-
-trying the conventional method to unlock which, as mentioned by my friend above, ended up with an unknown error-1 screen after all the way up to 99%.
- deleted my mi amount and made a new one with the same sim... Even added the account to device and used as new.
When i tried to associate the device with this account i recreated, a message pops up saying " can't add any more accounts to this sim".
- As tragic it may seem, i settled for a user experience with the stock mi bloatware... Until i realised if the "sim" is the problem, why shouldn't i try a new sim.
- Grabbed my mom's sim card, went on to create an mi account linked to that sim, apparently found out that i had already created one for her but never used to root her device ( redmi 1s).
-I slipped the sim card into my phone, added her account, and even associated the device to that account of hers.
-Eagerly fired up the unlock tool, smashed the unlock button impatiently, to find out a message that asked me to wait for 72 hours until the next try.
- now i am at my 42 hours remaining Mark, and not even sure if it will work.
So what do u ppl think? Is it worth the wait ( like ot or not i have to) ? Or am i better off grabbing a different sim card which doesn't have an mi account.!?!? And will i be asked to wait regardless of whether a sim had or didn't have an mi account before.

Strange! I have locked the bootloader a couple of times by mistake. And I didn't have to wait to unlock it again. As soon as logged into MiUnlock tool using the same account, it unlocked the bootloader within a couple of seconds.

so did you login to your device using password or the phone number? and even in the unlock tool, what did you login using?

fired up the mi unlock tool,
i had already added the account to the device and associated with it.
Tried a few minutes ago, to unlock the device.
Unlocked!!!
No resets no nothing, just had the new account running for weeks now.
Thank you ppl...thank you.
Back to rom frenzyyy!

create new mi acount, add, sync, use mi unlock tool and wait for 72 hours.

---

I think the people who had problems, were the people who lock the cell with the beta rom, not with stable rom...

Hopefully you read this.....I am in similar situation trying to unlock a mix 3. I used my sons sim to get to the 72 hr unlock...After that i popped my sim in. I am waiting the 72 hrs....When that happens, do i need his sim again when i try the unlock? Or will it work with mine?

I don't know whether the method you are adopting will work but with your sim it will not work since the request was given when the other sim was in. You will need your son's sim at the time of unlock.
