Android "Optimizing apps"

It took a very long time and I decided to restart the phone, turned out that it cost me my whole data - it factory reset, then I realized that Android was not fully installed, because it simply was missing key apps - such as Updater (Huawei). After that, I tried to factory reset to recover those system apps, but it doesn't even work - it says that it fails everything - starting from Huawei EMUI (firmware) flashing to rooting. IT FAILS! I want to ask you guys, am I able to optimize apps manually in order to "finish" what caused the problem in the beginning? THANKS, I've been trying to figure out this issue for 2.5 hours, I'm really nervous at the same time.
info: model: Huawei Ascend P7 L10
Android version: 5.1.1 - EMUI 3.1 (EMUI is Huawei's custom firmware).

Reflash official ROM. Put "Update.app" in a "dload" folder on your SD card and then turn off your phone. Press and hold all 3 buttons until screen turns on, when it does release power button, but keep holding the 2 volume rockers down until you see EMUI logo.

I think I've bricked the Huawei P9

I have a European Huawei P9 EVA-L09 model which I adore. It was running Marshmallow and EMUI 4.1. I found a Nougat beta ROM and I tried to install it but have left it in an unusable state.
I don't think the phone is rooted but I do think the bootloader is unlocked.
I can boot into 3 modes.
Mode 1 - Just reboot
Huawei eRecovery where I get the options to download latest version and recovery, Reboot and Shutdown. If I select the Download latest version and recovery it setups my Wifi and then fails with the message Getting package info failed.
Mode 2 - Power + Vol Up
It boots into a screen that gives me the option to Reboot your System Now, Wipe data / factory Reset , Wipe Cache partition. Selecting Wipe Data/Factory reset returns back to this screen with an error - Red Exclamation mark. Selecting Wipe Cache partition seems to perform a wipe and returns to the original screen with the 3 options again.
Mode 3 - Connect to PC with Hisense and power + vol down
This goes into an android recovery screen which is white with a green android displayed
I have the USB drivers installed on my PC but I cannot see the phone in Windows explorer when I plug it in via USB. I do hear the recognition tone that Windows has recognised that a USB device has been attached. The Huawei PC software doesn't recognise it unless I go into the white android screen and select recover. This always fails saying it cannot find a package.
I have installed stock P9 Marshmallow firmware on my SD card in a dload folder (which is how I bricked it in the first place. When I hold Vol up and Vol Down and power it starts installing but then fails about 40% - 50% through. I have tried multiple versions of the L09 firmware but none of them install successfully.
I am not very technical and not an android expert so cannot say I have done everything perfectly correctly. #
Is my phone bricked or is it possible get my phone back working?

You can get your phone back, search the forums for dc phoenix, which has helped people including myself.
The other option is to go the huawei website, and look under downloads for p9. Find the two firmwares for beta rollback and follow the instructions, although i am not 100% confident that will work for you

use dc phoneix ... i was the in tha same condition

So I have installed and tried install a few different ROMs to the phone. DC Phoenix recognizes the phone as it comes up with the IMEI and version in the left hand window. It seems to install the ROM sucessfully.
I get a message at the end saying it finished successfully but when I boot back up it just goes straight into the same eRecovery screen I have tried B166 and B322 and no luck. Is there anything different I should be doing?

...and now I have a new issue
Thanks for everyone's help. After downloading and trying about 10 different ROMs I was able to get a Nougat ROM to install. Now I have a different problem
1. When I reboot I get a verification failed message. I get an option to go to eRecovery (which works the same as above and doesn't find a package)
So what I really want now is just to get back to stock Marshmallow and not have a verification message and not have some Nougat version that doesn't look like the official Huawei ROM.
So what next folks?

I encountered the exact same problem a few days ago. I didn't try DC Phoenix, instead sent it to Huawei for repair, claiming the phone was in a boot-loop I couldn't recover from.
They have fixed it now and the P9 is on its way back to me. What's strange is that they have swapped the whole motherboard for a new one! Didn't expect that.

Help needed (stuck in Huawei eRecovery)

I had my P9 Plus (VIE-L09C432 B370) boot unlocked, rooted and running twrp recovery. Wanted to reset everything back before I sell it.
Tried to relock bootloader and flash stock rom. But that did not go well.
I can boot into Android, but lots of apps are missing (file manager, keyboard etc) and I can boot into fastboot.
Tried uploading /sdcard/dload/update.app and hold vol up+down + power. But the update process stops as 5% and the phone reboots.
Any tips on how to get the phone back in order?

Try this: boot into android and restore via huawei desktop software.

HiSuite says my device is incompatible when I try to restore when it's in fastboot. When in Android it says it does not need to restore. But now I'm stuck in a messed up B370 which has not keyboard (only google speech) and is missing lots of other apps as well.
What's the latest firmware that it will let me fully reset to (via vol up+down + power) and using sdcard/dload/?
I tried B360 which seemed to work, but it still came up with the messed up B370.

try to downgrade to marshmallow and then update to nougat, it should fix. I had your same issues and I fixed it flashing the "data_full" part of the firmware, but it was something like 10 months ago and I don't remeber the exact procedure and the files I used. If you downgrade to 6.0 iirc you take your p9+ back to stock settings (locked bootloader) and then you can update it to nougat with official huawei firmware via the updater app on the phone.

Could you provide any information on how to do that? The only firmware I've been able to get the updater past 5% is B360 full. Any other stops at 5% when I do the (vol up+down + power and update.app in /dload).
I've tried:
B160 (Marsmallows, fails at 5%)
B170 (Marsmallows, fails at 5%)
B360 (Nougat -> Goes to 100% and reboots, but device is still B370 with missing apps)
B370 (Nougat, fails at 5%)

Ok, so: download this https://mega.nz/#!wswElLwA!qhafrd_13kW8RjYUEjIXT2lxVEgh1DtjUF-DgzuzqlE
And this https://www.androidfilehost.com/?fid=24533103863142914
Now, put the update.app that you find in the first rar in your dload folder on the SD. It must be the only file in the folder.
Dload your phone (vol+, vol-, power). Do this twice.
Boot your phone and check the serial number, it should be l09c900b300.
Power off the phone, replace the update.app in dload folder with the that you find in the secondo download link.
Dload the phone again and boot it, now you should be on emui 4.1 fw b103 with locked bootloader and valid warranty.
You can update the phone to nougat with stock updater if you want. I'm on mobile, so if the post is bad formatted well, sorry, I'll fix it when I can access a pc.

That's for the C900, I've got a C432. Won't that be an issue?

Files are for c432, mid procedure you get c900 cust which is the generic one.. after you flash the firmware (second file dload) you are back on c432

Bricked Honor Play (Boot Loop)

Hi guys, I have a Honor Play (COR-TL-10) and I was trying to install emui 9, got the COR-L29 emui 9 version installed by HiSuite (used a russian program called FirmwareFinder for forcing HiSuite into installing it, I know, it was stupid) and now my phone is stuck rebooting all time, I can't even turn it off, what do I do?

Would it be possible to start the recovery mode? And then wiped cache

I already tried wiping cache (while I was able to go into recovery mode), and it didn't help. Now I can't enter in the recovery mode

All fixed
Shipped the phone back to the seller in china and they fixed it, just received the phone today and all is working.

Missing Camera, Calendar, etc after factory reset

Hi all, here are my phone specs currently:
EVA L19
C636 B393
EMUI 5.0.1
Android 7.0
bootloader unlocked
magisk installed
The phone has been great for the past year, but yesterday I did a factory reset (maybe bad move, should have done TWRP wipe) and there are no essential apps anymore like camera, calendar, and the rest.
I've been scouring the forums looking for a solution but most of the download links are dead.
Tried to do an update via HiSuite but nothing happened after installing.
Any other ideas? I don't want to install a custom ROM as I prefer the stock camera app.
Thanks!

Try deleting Dalwik and Cache from TWRP or deleting Cache from eRecovery (switch off, connect to charger!!!, press and keep pressing Vol+, boot by Pow)
You could also try again Factory reset immediately followed by Wipe cache - both from eRecovery
There is also an option in eRecovery: Install latest firmware, you can try but not sure would it work since Huawei apparently removed P9 firmwares from their servers
Otherwise, you would need to find (it was easy in the past when FirmwareFinder worked), download and reinstall your EVA-L19c636 b393 (or newer)

Hey there, factory reset from both phone and TWRP didn't work. eRecovery can't find package info too.
So I downloaded the firmware now and put the dload folder on my SD card but I can't force it to update. When I press the vol keys +- and power, it just says "your phone is unlocked and can't be trusted etc..." and then just boots normally. I can't access ProjectMenu using the *#*# codes either.
Any other ideas how to flash this firmware?

Unfortunately, no other idea but try to find DLOAD package.
Several other users asked similarly, pleas see the other recent posts here for P9 - but generally, it will be hard because Huaweu removed firmwares from their server.
See in those other threads/posts for alternative catalogs.
Unfortunately, c636 is relatively rare, consider rebranding to c432 - and again, look to thoso other threads, recent questions and answers

That's where I'm stuck though... even if I have the firmware I can't force update it by the button method of the secret codes method...
I'll try to flash via fastboot and hopefully it works.

Update: got the C636 firmware and the flashing steps here:
Huawei P9 [ROM][Android 7.0][EMUI 5.0.1][European Firmware b394]*MagicRainbow* v3
