Chinese variant....rejjoice...B595 released on FF....
Should come in a couple of days.
Changelog is exactly same as B593. Do not understand why the update then....

maybe bugfixing?

question to you folks: im having trouble relocking my bootloader in preparation of selling my mate 8. i went back from B592 to B386, that locked the BL. but once i updated back to B577 and B592 it was then unlocked again, wth...?

unfortunately, im not getting an update to B593 yet...

You should have it locked.. Strange. It cannot unlock by itself ever??? Without code? B386 locked and then B577 unlocked? Crazy... I always have it locked if upgraded with locked bootloader.
Regarding B593, you can update through HiCare. Unlimited quota is there.

yep, completely strange and crazy! went back all the way to B197, these are the results:

B592 unlocked BL (start)
B386 (locked)
B197 (unlocked!)
B368 (locked)
B386 (locked)
B577 (locked)
B592 (unlocked)

all by itself! no input of BL code, i checked via fastboot after installing each and every rom. its like my mate 8 wants to spite me cuz it knows im selling it off

good idea with hicare, lets hope B593 locks the BL again...

edit: no dice with hicare, not showing any updates. ive tried china, singapore and germany as regions, should i try another? also, do i need to register an account to get the update? that wasnt necessary before in hicare, but just making sure nothings changed in the meantime...

I dont know why? I got it and always use to get it even with unlocked bootloader from Hicare.
I will need to go back in that case and check once again if I am getting through hicare or not. Give me sometime.

much appreciated my friend im thinking about trying to manually flash the oeminfo partition via fastboot, that should theoretically also result in a locked bootloader...

LOOOOOOOOOOOOL!

ok guys, just that you know: i think im turning insane over here HAHAHAHAHAHA!!!!

wanna know why? ok, ill tell you why: flashing the stock oeminfo for AL10 did NOT result in a locked bootloader.... HOWEVER!

I managed to get rid of that annoying orange message at boot saying that your phone is insecure!!!! with the bootloader still unlocked! *rofl*

NOW of all times, after I already got a new phone and ready to sell off my mate 8 did I find this

ok, so anyways, i figured i should share this because im sure lots of you guys would be interested in this.

Prerequisites and things to know beforehand:
- make sure your bootloader is already unlocked when you start off with these steps!
- this procedure involves a factory reset with data partition format, so MAKE A BACKUP OF YOUR IMPORTANT DATA BEFORE YOU DO THIS!

so, without further ado, starting off with a stock rom (B592 on AL10 in my case), do the following:

- fastboot flash the latest twrp you can get your hands on (i used the one by openkirin, version 3.1.1.0, but i actually saw that brother @ChinHon actually provides an OREO based TWRP for mate 8 now, whats up with that?!)
- boot into twrp and flash the latest stable SuperSu zip (2.82) to get root access
- now try to get your hands on the correct oeminfo file! unfortunately, all links ive found here in the forum were dead, BUT: head over to the SRK Tool thread (Link: https://forum.xda-developers.com/mate-8/development/tool-srk-tool-huawei-t3369797) download that nifty tool by brother @somboons, unzip it and look into the folder named "oeminfo_mate8", voila: there you go available for China (AL10), Asia (L29C636), Europe (L29C432), Middle East & Africa (L29C185) and theres another one called "normal", no idea what that is for, maybe the global version (L29-C900)? anyways, unzip the oeminfo zip and youll have the oeminfo file ready (note: it does NOT have a file ending!)
- get yourself a file explorer with proper root capabilities and the ability to unhide hidden files, i myself use es file explorer pro, and replace the oeminfo file you just downloaded (make sure its the proper one for your model) with the original located here:
/dev/block/platform/hi_mci.0/by-name/oeminfo

A reboot will now tell you that your data partition is corrupted, so you will have to use erecovery to download the latest stock firmware and recovery (involving a complete reset and wipe of your data partition, so be sure to make a backup of your files first!). this then leads to a freshly installed stock rom with an unlocked bootloader and NO orange message during boot

in any case, ill leave it like that for now, ive stressed enough over relocking my BL

if any of you guys wants to open up a new thread for this finding for better visibility and maybe properly rewrite the procedure including links, be my guest

ill be uploading a video proof on my mega account shortly, stay tuned

Great trick.
Does not install the new TWRP 3.2.1. It boot / is / only for Oreo !

right....soooo....what is it for then? since mate 8 doesnt have oreo? at least not yet

 

[veromax]

I don't know anymore, but I've never experienced twrp officially bringing recovery for a firmware that doesn't exist yet.

hmmm, very interesting indeed: https://eu.dl.twrp.me/next/

but, say, have u tried booting the 3.2.1 version on nougat yet? oreo compatibility was improved but changelog doesnt mention it not working on nougat... besides, my mi max 2 with lineage os 14.1 (android 7.1.2) is running flawlessly with twrp 3.2.1, although it might of course be something different on the mate 8 with emui firmwares... for example, i remember there being specific twrp versions for emui 4, emui 4.1 and emui 5.0 that werent interchangeable, rather depending on the currently running emui version!

I tested it on the M8, 6x premium and the PRA. No booting possible. Try the installation tomorrow by adb. Then let me know if it's okay.

I just installed twrp via adb. Doesn't boot either. At my mate 8 and honor 6x the nougat twrp's also didn't go on MM.

that sounds very promising in terms of upcoming mate 8 oreo. makes you wonder how exactly the contributor for the official mate 8 twrp, paulobrien, tested that version... maybe he just implemented some standard tweaks for mate 8 and otherwise just used the generall 3.2.1 base without the ability to test it? or he ported it from a similar specced phone? huh...
