Sorry for a tangent question.
The guide linked by OP is for ALE-L23 model, but would it work for ALE-L21? If that is unlikely, are there any guides for ALE-L21?
Finally, other than the model number, what else is important to match-up when trying to install custom roms?

very important -> model number (ale-l21 must be ale-l21 and not ale-l02 because they have another chipset)
important but fixable -> location (c432 must be c432 and not c034 (making things up))
also important but fixable -> dual sim and single sim
something to take into consideration -> android version
so if you have the next version ale-l21c432b564 don't flash ale-l02c69b049 over it

My phone is ALE-L23C605B140, so all sorts of different from what I see in those guides. Is it possible for me to downgrade/upgrade to a version that's compatible first, or do I just need to wait for a guide that works specifically for my phone?
My phone is also dual sim, and running Android 5.0.1 if that helps.

Thanks. I also saw it when browsing the forums earlier today. I'm now at the part where I have to wait 14 days (created the profile 3 days ago so 11 days to go) and will post again if I still get the "page not found" error or if this thread can be closed.

If your phone is bricked and you didn't unlock the bootloader, flashing the OS using dload and 3 buttons method is the best way to get it back. Give it a while to boot up for the first time and unlock bootloader proper way.

So it wasn't so hard to get code without ID, just need some help with programs So my job here is done, if anyone else have bricked Huawei P9 Lite, just tell me
we are at the same point... no.. wrost than before... bootloader unlocked. nothing installed
Cmon dude, what are you doing? Try doing same as I did... Via fastboot
Man unlock code is generated from EMUI site using imei, serial number, product ID and are unique for every device.
If it was that easy with a simple fastboot command I would already did it, it's not that I don't want to help you. Inform yourself..
Yes, product ID is based on IMEI, so it can be generated that way, this is how I got it
Then generate it by yourself and report back
I already did, thanks anyway
I cannot find my model in this page

I understand but already for two months already waiting to load. is there no other way to do bootloader unlock?
I heard you can use DC unlocker, I'm going to try it, bacause the unlock page is down already and there's no way to get officially the unlock code. But someone said the Twitter page support gave him the code, so you can try it too, I may try it too.

Just register a new account with email option and India selected as country, and after that you could see unlock page, I had the same problem as you with my main account, some countries got blocked from unlock page! so it never loads, just use a new account before it's too late.

Hi guy,
sorry I expressed myself incorrectly, I did not want to know your stuff, I was just trying to figure out what was wrong with the updates of your branded version. Anyway, you need a rebrand.
I think changing to the European version no brand (C432) is the best choice.
There are several guides, in which you will also find the files used for conversions.
You only know if you have a mono or dual SIM device, so you need OEMinfo and firmware version for your SS or DS phone.
Follow step by step the guide you choose, I suggest you read at least twice (three is better) the guides....
Here I place only a couple of guides (slightly different for how they do their job) taken randomly, but there are others, just use 'search' in the p9 lite's threads ...
All credits go to their developers, thanks guys ..
If something goes wrong, do not point the finger at me or other dev / users,
you and only you are solely responsible for what happens with your device.
Best regards
GUIDE 1
GUIDE 2
