If by reset you mean that I'll lose my personal data, I made a backup of contacts, messages, apps, and whatnot while on B182.

My instinct told me so, and I listened. Lucky me :)

I'm concerned about the things that I couldn't backup and that (I noticed) have disappeared from the phone *after* the update. For example, none of the stock Live backgrounds that have been around since B136 are there anymore. Will they come back if I reinstate B136 or B182 :confused: I sure hope so...

I'll do the down- and up- grades in the next days. I'll be back to report Success or Failure :fingers-crossed:

For now, thanks again.
[Huawei P9 Guides, News, & Discussion] Umb0:
1st attempt: FAILURE -- the phone didn't go back to the state it was in when last I had B182.

so I tried again...

2nd attempt: CATASTROPHIC FAILURE -- the phone is stuck at the Huawei logo. It won't boot.

Now I seriously need help.

My phone is stuck at the Huawei logo. It won't boot.

I can turn it off by holding the power button, but the device immediately and autonomously powers back on.

It is forever showing the Huawei logo and does nothing else.

I can't enter recovery mode because there's no way to turn it off.

I need solutions.

And please, I need them ASAP.

You can flash full rom via DC Phönix, i had the same problem!

Plug in USB, hit Power and Vol down and you enter Fastboot, here you can flash with DC Phönix.
[Huawei P9 Guides, News, & Discussion] Mostar088:
Dc-Phonix is the best solution.

[Huawei P9 Guides, News, & Discussion] Umb0:
Hi,

the battery has finally died -- the smartphone is Off.

Now, before I make another disaster I must know what's ahead.

As I understand, I have to buy credits for the DC Phoenix service I require.

I suppose I want to write a firmware... therefore I should buy the option DC Phoenix Firmware write (valid for 72h/phone)

Is this the correct choice?

And will the use of this program invalidate the warranty?

I mean, does the program unlock the device, or make that thing called 'rooting' to it?

What about the IMEI and the other id numbers... will they be changed or wiped in any way?

[edit]

Scratch it all. As I plug the phone and it starts charging, it resumes the eternal Huawei logo, preventing me from doing anything.

Looks like I can't repair it. I must send it to Huawei's assistance. I swear to God I will never buy Huawei again.
[Huawei P9 Guides, News, & Discussion] yasir04:
Yesterday I faced similar issue with another Huawei phone but I was able to enter the recovery mode.

I just put the update.app file in dload and updated using 3 key combination and it's working now.
[Huawei P9 Guides, News, & Discussion] Umb0:
UPDATE:

After calling Huawei's hotline I've been directed to the technical assistance here in my town. There I left my phone, meant to be taken back in 24 hours.

The next day (this morning) I go to take back what's mine, but my phone is no more. Judged unrecoverable (I'm gonna get medieval on the next dude I hear saying that it's tough to brick an Android! :mad:). I received a new phone, with new IMEI, new Mac address, and what not.

The rom within is C432B166, just one update away from the B182 I wanted to go back to. Fair enough.

The only neo in this affair is that in the HiCare app I can't register my new P9 'as mine' for the purpose of the gold VIP membership. I had registered the previous device already and the system rejects the new one. So I phoned the hotline once more, and they explained me that it is not a concern. To them I'm a gold VIP member, and they know which devices I have and what has been done to them. The fact that I can't register the new device in place of the old one is just a quirk of the system. I'll have to believe it.

[edit]

I forgot... I'm still set to never buy Huawei again, despite the quasi-happy ending of this story.

In just 4 months I've spent far too much for this device and it'll take years before I amortize the costs to acceptable levels. By that time the P9 will be an old thing in need of a complete hardware overhaul. And so I've learned another valuable lesson: don't buy flagships. Spend less, buy mid-range. If something goes wrong, you've wasted less money and (maybe) get less angry than I am now. Also, because mid-range costs less, you can buy the next best mid-range sooner, making it easy to stay on par with the tech-curve.
[Huawei P9 Guides, News, & Discussion] dracushor87:
Good to know that you solved it :) Huawei has a good service management in my opinion :) and i like the device. But we also respect your opinion :)
[Huawei P9 Guides, News, & Discussion] Umb0:
Hi,

I'm sorry -- I'm just bitter.

This is kinda OT. Hiding it...

That P9 was my own birthday present. I did so much to have it.

The first time around the e-shop I bought it from didn't have it in stock. So I got refunded, but by the time it happened I was 1 month past the birthday date.

At the second try (another e-shop), the package was delivered very quickly, but the courier left it in the hands of the janitor (or superintendent? Not sure what's the word for it) despite the fact that I was at home.

I was able to get a hold of the janitor only 4 hours later, and only because I actively searched for him. He was seemingly nowhere to be found.

Then I had to wait 2 weeks for the arrival of the screen protector (from the UK) and almost 5 for the TPU case cover (from the US).

Never a purchase -a birthday present, no less!- was more troubled than this one. And the other day it died for good. Perhaps it wasn't

destiny

for me to have it?

Now I got this replacement phone, as good as the old one, but it's not the same thing. Not the one I so desired and cared for.

I should be happy that I got my expensive device back... but it's another device. I'm not feeling any attachment to it :-/

Maybe I just need to use it for some time.

Anyway, to remain On topic, your instructions to make the rollback did work the first time around. I just wasn't happy with the end result, and tried a second time. That's when things got awry.

Was it completely my fault? I honestly can't tell. I know I can follow instructions, but if not even a technician could get his hands inside my device, there's no telling what happened anymore.

Hi, After a rollback from Emui 5 to Emui 4 B132 themes break. I don't have magazine unlock and i can't apply themes. Why?
[Huawei P9 Guides, News, & Discussion] dracushor87:
flash 136 with a full reset. some have expirienced this and a new flash solved it.
[Huawei P9 Guides, News, & Discussion] m00n61:
Had pretty much the same experience. Updated to Nougat then downgraded. Themes not working after update so decided to go back to Nougat. Something went wrong and got stuck in eRecovery. Took the phone to Huawei, they told me the motherboard is faulty and and am now waiting for the replacement.

Really disappointed by build quality. The phone was less than one month old.
[Huawei P9 Guides, News, & Discussion] Umb0:
I feel for you -- you have all my simpathy.

Were you a Gold VIP Member, by any chance? If so, you must keep the old phone's box, or at least its IMEI code, because you won't be able to register the new phone's IMEI for the purpose of Gold VIP membership.

Don't worry, your membership isn't lost, just tied to the first IMEI you registered. The catch is that you cannot unregister the first phone to switch to the new one. To extend the Gold VIP membership to the new phone, you'll have to provide your first IMEI (even if you have that phone no more) along with whatever documentation the Tech Assistance gave you when you received the new phone from them.

In my case the documentation was in the form of a receipt. On it were printed the Tech Assistance shop's name, date, time, my name and surname, and both the old and the new IMEI codes (labeled IMEI_In and IMEI_Out, respectively). But YMMV, of course.

Make sure to get the tech guys to explain you the thing.

The operators of the Huawei hotline can also tell you.

Good Luck! :)
[Huawei P9 Guides, News, & Discussion] m00n61:
Yes, VIP Gold. Registered on the first day. Guess that is why they went straight to replacing the phone. Thank you for the info, good to know. But for the future owner, as soon as I get the replacement I will sell it. One of the strong selling points for me was the camera and I found it average even in good light. The only thing I will miss is the back side fingerprint scanner, it is fast and, being on the back, this is the only phone that does not unlock accidentally.

The rollback package should work on every nougat rom (tested on EVA-L09B378, B383)

If not check your internal sdcard. There maybe is another dload folder or an folder (forgot the name) with update packages in it.

Delete them and your sdcard dload folder should work.

Yeah because you need to flash hw_init you can go back to MM firmware and use Firmware finder to flash B386, since by using that method it flashes the firmware correctly. And Firmware finder cannot override System Updater on nougat that's why yoi need MM
