[Huawei P9 Guides, News, & Discussion] lostunsunghero:
So i've been at this for the better part of 5 hours now. I'm stuck on C432B136 and it doesn't give me an option to update and says i'm on the latest firmware. I've probably soft bricked my phone around 10 times trying this and it's probably only a matter of time until I mess it up so bad it bricks completely. I don't know where i'm going wrong.

oeminfo shows hw and eu like it should.

new symptom after most recent attempt is at boot is gives me a message saying "your device has failed verification and may not work properly" in red rather than the usual yellow coloured message when you unlock the bootloader.

I can't seem to reflash twrp image despite multiple attempts. It seems to work but then when I try to boot into it as i've done before it boots the stock recovery.

At this point i'd be happy if I could get back to 6.0 emui 4.1 branded vodafone UK.

Any advice?

Is it possible to dload straight to 7.0 without any issues and then try and flash custom recovery? How would I go about doing that using the huawei updater application?

UPDATE: ran the unlock bootloader script on a hunch and it didn't require a confirmation on the phone like it did before, it showed the message asking me if I want to unlock and then booted into twrp. What the **** have I done to my phone where it is making decisions for me now? Is this the start of skynet?

Either way i'm not getting the red message anymore, it's reverted back to the yellow bootloader unlock message which makes me think I accidently relocked the bootloader without knowing it at one point. Phone booted up and now im at the decrypt storage screen. rebooting brb.

dload seems to be the easiest way to do this now. Whats my upgrade path to 7.0, which files do I need to download to make that happen and in what order should I install those files? Sick and tired of failed twrp flashes.

UPDATE: ive ascended to the great height of C432b166, I think? Got an OTA update after my last forced flash of b132 and its 35% of the way through. I think I worked out what went wrong. Being sleep deprived I thought that flashing the b132 file locked my bootloader again, which is fine, but i got a message on boot saying my bootloader was still unlocked which confused me. At which point i went through the steps to unlock and relock a few too many times so I could get an OTA. However because it was already locked I was actually unlocking it when I thought I was locking it. Turning what should have been a half hour job into an all nighter.

Don't make the same mistakes I did.

UPDATE: b166 is successful. I think i'll pick it up again when I've had some sleep but it should be pretty straightforward now. Just need to force flash B182 and then I can OTA to Nougat if i'm not mistaken.

UPDATE: well ****, now for some reason I cant relock the bootloader. I think it has something to do with my recovery not matching the ROM version, anyone know how I can extract a recovery image from the b166 rom and flash it?

UPDATE: So I reflashed twrp then flashed a stock recovery image which I extracted from the b182 UPDATE.app file. bootloader is now locked again hopefully I can OTA now.

UPDATE: Nope. that red error message is back. definitley something funky going on with the recovery I'm flashing.

UPDATE: reluctantly force flashed b182 it works and unlocked/unsafe bootloader messages have gone which makes me think it fixed itself. ROM seems stable and works. Now to figure out why it wont OTA to Nougat.

FINAL UPDATE: ok so basically what this has taught me is that im an idiot and had I followed the instructions properly from the beginning then I wouldn't have made this mess. However I did learn a lot about huawei phones in general by making the mistakes that I did (having come from a samsung/lg background) Now running b361 following this guide:

hopefully this is the last thing I need to do.

FINAL FINAL UPDATE: woohoo Android 7!

if anyone has any problems feel free to ask because i'm pretty sure i ran into and fixed just about every problem that could possibly happen doing this process short of turning my phone into a paperweight.
