So here's what happened:
Got a message to reboot my non rooted Mi A1 in order to finish the november update
Clicked on it and waited for the reboot, which took a while
Screen kept flashing, but mostly a black screen with now and then a flash of my background and the task bar in the top of the screen.
Went to this forum to find answers and solutions
OEM was locked and couldn't access the phone, so unlocking OEM and flashing stock was not an option.
Saw someone mention you can switch the active partition. It was set on B and I changed it to A.
Phone works fine with that option, but the message that the update has failed keeps popping up and it gives an error when I try to redownload and reinstall the update.
If anyone knows what the recommended steps are to fix this issue it would be most helpful!
PS. Also if I have to unlock OEM that means it will wipe the phone right? Any tips on backing up the apps including their user data (meaning I won't have to reconnect authenticators to my phone, won't lose game date etc.)
Try to remove sim and disable PIN.
Hi,
I have also a non rooted phone with the same problem.
Can you please tell me how you have solved it?
Many many thanks!
I haven't solved it yet. Still looking for help!

Yup that is the same issue. Can I contact you somehow? I semifixed it in that I can use the phone again, but updates are impossible.

Hi, yes you can! You can send me a PM by clicking on my name.
I have the same issue and the only way that I find is flashing October stock firmware and select the active partition A and then upgrade to November OTA update

Hi,
I am very glad there is a solution but I am a noob on this topic.
Do you have a step by step manual how to do this please. Thank you so much!
It's no problem if I will loose my data.

Does that method wipe the phone? If I am correct you have to unlock the bootloader which requires a complete wipe of your phone.

This actually works! No flashing anymore when removed the sim card.
But when I place the sim card in again. It's starts flashing again
I placed the sim in another phone and removed the pin for the sim card, NOT THE PHONE and yes I can use the phone again.
Thanks so much!

Yes. There seems to be a bug in the PIN screen. So when you disable your PIN you can enter your phone.

You can also take out your sim from your Mi A1, boot your Mi A1, disable pin in settings, shut off, put your sim back and boot.
That's what I did with my wife's phone.

For now. When you set your device language on English you can use your PIN. Otherwise wait till fix.

I think you can also prevent your device before booting by a pattern, etc.
It's no the best I am really happy the phone can be used again.
I have to install everything again because I tried several factory resets
Dont update to November patch, in my case battery life is worse.

Hi, I am not happy with the latest update (V1.15.40.639) and would like to downgrade to the previous one (V1.13.40.496). I read on zentalk forum that we can downgrade by downloading the latter firmware from asus site(http://www.asus.com/Phone/ZenFone-2-Laser-ZE550KL/HelpDesk_Download/) and place it on SD card root. The reboot to the recovery and select something like "apply update from external". Can someone confirm if this will work? Is there an easy enough and confirmed way to downgrade the firmware. Any help will be much appreciated.
Edit: The method works!
Haven't done that but it should work, if you face any app crashes you will need to reset phone
Pls don't downgrade it will kill ur phone

He is wrong xD
Like I said the you'd face app crashes which you can fix by resetting phone.
If you are not comfortable to do this then simply go to service center and tell them you want certain update flashed for whatever reason.

Did you actually go into recovery and flash the previous firmware or just let the phone detect the firmware and install it by itself?

I placed the update on sd card. Booted to recovery. cleared data and cache and applied the update via SD Card method. The cleared cache once more and rebooted.Voila!
This method is going to wipe all user data???
Probably a reboot would do the same result.
I have, like many others, the latest firmware and I didn't encounter no problems. So definitely is not the firmware itself.

LOL. That's one question I never ask. It's always a good idea to do a backup before any update, especially if it's a full firmware flash and not an OTA update.
No. I only wiped cache and it seems to have kept the data intact at the time. I had a backup for safety's sake but I did not need to restore it.
Can We root the phone after downgrading it to lollipop using Kingroot?

Yes, turn on your phone, take your sim card out and re install it, go to network setting and set it to global, leave it like that for some time and it will automatically set your network.
I have had same issue, after updating a rom i get no network. So i set it to global and leave it like that for almost an hour then when i reached my phone again, its connected to network.
Didn't help

Dunno why its sim locked. Did it used to detect sim before?
If you want to unlock it, refer to this thread : http://forum.xda-developers.com/showthread.php?t=2455956
You might need to pay couple bucks.

7.12.7_7.1, after that, my movile bootloop every 30 secons more or less
Now, when i turn the mobile on, it tells me that the SIM is blocked, but I tried the SIM in another mobile and it works
A/B partition are there so if device is stuck in bootloop it should boot from dormant partition.
You have to flash stock firmware.
Try flashing the persist.img from every build that exists till now. If you manage to flash one of them the issue will be fixed. I've tested it myself.

Please just follow the guide here to get it fixed: https://forum.xda-developers.com/mi-a1/how-to/ota-official-fastboot-image-n2g47h-7-12-t3728929
As it includes all necessary scripts for proper flashing it is secure to use
In worst case, you can also use the appropriate included script to factory reset at the same time when flashing. If nothing else helps, that should do the trick for you

I tried flashing persist.img, and it works!!!
Now I have 2 differents problems.
When I start my mobile, the SIM Pin page shows the message SIM CARD IS LOCKED - NO SERVICE. My sim works in another mobile
When I pu my pin, I get the message "preparing sdcard - Solving errors"
Please just do a full clean flash as recommended by me earlier and your issue should be gone. At least if they are firmware or software related.
After that do a clean flash and that issue should be fixed.

Excuse me. What do you want to say with "do a clean flash"?
Follow the guide I linked for you above. You have to use the flash_all script. So please have a look and give it a try.

Shooting blindly here.
Have you tried another sim in your phone.
If another sim card works then have you tried changing your sim from carrier. It's easy.
Have you also tried a factory reset?

My phone show me the page with de SIM Pin. I put the correct Pin, and after that phone don't connect with the network. I can't call because it's without service.
I tried the same SIM in another phone and it works. I tried diferents sim in my phone and all of them fail

A mother's friend died recently and we try to get access to her phone to find any clues. The problem is we can't access the phone. I was thinking about installing TWRP to get access to her phone files but that is just half the solution. Any ideas to get full access to the phone ? Any help would be greatly appreciated. Thank you.
