[MENTION=5562770]rajperth[/MENTION] So you did change the Proxy port and address where this image is right?

http://prntscr.com/fjnf67

[MENTION=1256290]Tribal123[/MENTION] If the option is not greyed out and toggleable then the bootloader is locked.

If the option is greyed out then the bootloader is unlocked.

You can check if the bootloader is locked via enabling USB debugging and running the command 'adb reboot bootloader' with the phone connected to computer to reboot into bootloader mode then you will be at a white screen showing bootloader unlocked / FRP unlock or bootloader locked and frp locked (on).

TL:DR - Unlocked bootloader does not allow you to select option in developer option and is greyed out. The locked bootloader allows you to toggle OEM unlocking in developer options.

[MENTION=5602110]benjamen50[/MENTION] - indeed! I've followed everything in the instructions to the letter. I can't see myself progressing past this point without further guidance but thanks for your help thus far...
[Huawei P9 Guides, News, & Discussion] Tribal123:
Thanks [MENTION=5602110]benjamen50[/MENTION]

So if I want to root the phone I have to:

1) unlock the bootloader

2) re-install the twrp

3) root

At the end how can I re-lock the bootloader?

If I don't lock again the bootloader the phone will receive OTAs updates?

[Huawei P9 Guides, News, & Discussion] benjamen50:
Correct.

Relocking the bootloader is done by getting the phone into fastboot mode then typing in command prompt (where you open it at the folder that has fastboot.exe) while phone is connected to computer:

fastboot oem relock <insert bootloader code here>

and that will relock the bootloader. Unlocking the bootloader will perform a factory reset on the phone. Relocking would do the same I would assume.

Make sure you set in developer options first when bootloader is currently locked 'Enable OEM unlock' ENABLED (set to right)

Some extra commands (for use with adb when phone is on with usb debugging enabled and trusted to computer):

adb reboot fastboot (To reboot phone into fastboot phone)

adb reboot recovery (To reboot to custom recovery, if you have one flashed onto phone)

Command you can use to reboot out of fastboot mode:

fastboot reboot

Has anyone had issues with further software updates? I'm currently on b383 and I am being prompted to update to b386 via ota. I download the package then during the install it fails at 5%. Tried also installing through the firmware finder and have the same issue.
[Huawei P9 Guides, News, & Discussion] mal_berto:
Thank you so much for this guide. It was really easy.

Step 6 was not necessary for me. After phone rebooted on the B182 firmware I was able to upgrade vía OTA to B383 and then to B386. In your face Telcel!
[Huawei P9 Guides, News, & Discussion] Shred17:
I decided to take the plunge and debrand my Optus phone yesterday. Thanks to the guide, it worked without a hitch. After going to B182, it upgraded to B383 then B386 OTA. Happy!

I think my phone is soft bricked on boot up it hangs at the, 'Your device has been unlocked and cant be trusted' screen and says ' Your device is booting now' but it never boots and just hangs there. I have tried the UPDATE.app file from 'dload-huawei-p9-eval09-eva-b136.zip' posted in OP but when i try and force flash (VOLUME UP+DOWN+POWER) it just hangs on the Huawei logo screen. Any ideas how i can get the file to flash?

Hey Guys, could any 1 help me pls? I cant follow the instruction cause #1 didnt work. the update stops at 5% and says the version is incompatible. Does any 1 have an solution 4 me? :/ My phone have fw L09C02B341
[Huawei P9 Guides, News, & Discussion] Shred17:
Did you copy the whole dload folder from the extracted dload-huawei-p9-eval09-eva-b136.zip to the microSD card?

That's all I can think of that might be causing it to fail.
[Huawei P9 Guides, News, & Discussion] wyko2k:
ehm... yep, is that the mistake?

Edit: i tried with only the update.app inside, didnt work... :/
[Huawei P9 Guides, News, & Discussion] mikewilc:
Yesterday I've got Huawei P9 Vodafone with Nougat onboard (EVA-L09C02B3xx). I was trying to debrand using standard procedure, unfortunately it was failing at 5% with incompatible build message.

So found the following solution:

1. Rolled back to C900B300 using official Rollback Package - don't bother with build name afterwards

- downloaded from official Huawei site, copied \dload\update.app to sdcard:\, restarted mob with pressed vol up+down+power buttons until flashing started

2. Rollback to HUAWEI_P9_Firmware_EVA-L09_Android 6.0_EMUI 4.1_C432B166_United Kingdom_Channel-Others - you will finish with EVA-L09C432B166

- downloaded from official Huawei site, unpacked dload to sdcard:\, restarted mob with pressed vol up+down+power buttons until flashing started

3. Unbranded OEMinfo using post # 1 to get phone purely branded to EU generic C432

- using SRKTool unlocked bootloader, injected TWRP, installed ZIP and rebooted

4. And then all started to updating smoothly up to B387

At step 6 you say, 'you need to now update the firmware to B361 via Huawei Updater 2.0 using this guide: https://xdaforums.com/sho...80&postcount=2.'

But in that thread for the instructions it states, 'Only works Unrooted devices and locked bootloader', so are we supposed to use that method or not?

Also my phone shipped with C432, does that mean i can skip the first few steps and just go straight to unlocking bootloader?
[Huawei P9 Guides, News, & Discussion] mikewilc:
Hi, if you are on the C432 you don't need to write oemimage so you don't need to unlock bootloader.

just use HISuite with Huawei Updater to update to B360/B361 and then to B378 (or B387 - hardly remember these numbers)
[Huawei P9 Guides, News, & Discussion] Shred17:
If your phone shipped with C432 then isn't it already an unbranded UK one and updated to the latest build?
[Huawei P9 Guides, News, & Discussion] BlockABoots:
Yeah there is no operators logo on boot up or on the phone at all, it only seems to update to version b182 and then says there is no new updates, but my phone is currently bootloader unlocked, so can i still just start from step 6 of the guide?
[Huawei P9 Guides, News, & Discussion] BlockABoots:
The update to B360 didnt work after the update file had finished downloading and updating the phone restarted but then booted into TWRP and didnt automatically start updating. Any ideas?
[Huawei P9 Guides, News, & Discussion] mikewilc:
Not sure but your phone should be running stock ROM, dunno what TWRP is doing there...

Try to revert to stock ROM, don't unlock anything and begin from the point 6
[Huawei P9 Guides, News, & Discussion] thirtybob:
Finally got around to sorting it out. What I did was download B182 fw and copied to SD card then used the hidden menu (*#*#2846579#*#*) >software upgrade >SD card upgrade. It hit 99% and said "install failed", but when I checked " settings>about phone" it actual showed the B182 fw. Then went to "settings > update" and received OTA update of Nougat, Android, EMUI 5., B383. Checked update again and received B386 OTA. So all looks good for future OTA updates. One other thing, not sure if battery is so good, but can't be certain as its only been a day and I've been playing around with the new features. has there been any reports on battery life?

[Huawei P9 Guides, News, & Discussion] Otispunkmeyer:
New to this

Hi all,

Very new to this but I think I should be able to give it a go.

My other half has an O2 (UK) branded Huawei P9 and O2 are so useless it hasn't even seen a security patch since we got it in October 2016. Still runs MM with EMUI 4. Not good enough IMO and they're still dragging their heels / probably written it off.

So my OHs phone is on:

EVA-L09C40B190

Will this method work? And do I need a micro SD in there to make it happen? (I'll have to buy one if so).

In the meantime I shall register with Huawei to get a boot code.

Many thanks.

(Edit to add: there is no O2 splash screen on boot, but it is locked to the O2 network and the updater doesn't pick up any ota updates, ie the above firmware is the latest)
[Huawei P9 Guides, News, & Discussion] Razor10707:
Sup i dont know if you managed to fix your problem or not because i didnt reat longer so if this still up

This might work:

Method 1: download a rollback file for your phone youcan try other rollbacks like c432 or c185 if it install it then your doing good make sure your on eva-lxxc900bxxx if you have that flash the stock rom with the same cust like c432b130 or c185b130 etc and you should be able to install stock MM

If that didnt work

Method 2: unlock Bootloader then flash twrp for emui 5 (make sure its for emui 5 becasue your phone might go into error mode then download the oeminfo you want (anything you like c432 c185 anything) then download the right nougat file for it make sure its a flashable zip for twrp not dload method then after you downloaded everything reboot to twrp do a factory reset and delete cache and dalvik (you can delete system if doesnt work) just make sure dont delete internal storage or external sd (just dont wipe the storage where the oeminfo and nougat rom is placed) then go into install find the files that you downloaded and install this way: oeminfo then update.zip then hwdatafull then reboot (make sure you done it right if you deleted system as well because you cant reboot to twrp as long as you wont flash it again)

[Huawei P9 Guides, News, & Discussion] RodneyReid:
Just a recap of what it seems that I need to do as well as some issues I have with the current guide.

Current Build Number: EVA-L09C16B170 (South African MTN built)

1. Download and flash C900B136 using 3 button method or manual flash *#*#2846579#*#*- Unable to flash - Gives 5% error / Incompatibility error -

is the downloaded file not compatible due to country code or B170 built?

2. Unlock bootloader and install TWRP recovery using SRK Tools

3. Use TWRP to flash C439 OEM Info

4. Repeat Step 1

5. If B166 - Wipe partition and factory reset - update to B182 using updater in settings.

6. Update software - use Updater program - Link provided for B361 is not available anymore - any alternatives ?

Any one able to advise on the issues marked in RED

Even though I dont like my Samsung anymore - its definitely easier to flash Samsung software than Huawei

Tx,

I finally managed to update to B360 using the method described.

I was still not offered an OTA update any further but using the HiSuite without proxy the gave me the option for B378 which has installed fine too. Have not pursued any further so far so will see if I'm offered any other updates.

I had been wary of trying B360 as Firmware Finder showed it as not approved for my phone, but using the HiSuite with the details above it installed fine and everything worked.

I made a huge mistake.

I have EVA-AL00 Chinese variant.

I followed the instructions above without understanding the dload method. I followed the steps, flashing from TWRP. After flashing dload-huawei-p9-eval09-eva-b136.zip in TWRP, phone now only boots in eRecovery mode that always fails to update or restore.

In the bootloader mode, I can see that the phone is unlocked but FRP is locked.

When I run the DC Phoenix tool, it says that the phone is EVA-L09 with EVA-L09C432B136 firmware.

Please help! I need to restore everything back to factory!

Huuuuuuuuuuuge thanks for the OP! Worked perfectly for me even better!

I followed the steps one by one, the last one (Huawei updater) didnt work the Hisuits tells me that there is no internet connection after setting up the proxy.

Basically after the first step i had the OTA of 182 available, after it the phone gave me directly the 363 update so i did it... Now my phone is running Nougat EMUI 5.0 so thank you again i hope everyone will get it

Hello SIr, i wish to start this procedure. i have a few questions

Make sure you have the stock recovery already flashed and make sure your phone is not rooted (may not be necessary but this was the state my phone was in). - i currently have C627B140 P9 LG Uplus branded with EMUI 4.1. should i continue with step 1 on this setting? it has a LG UPlus login screen and a few UPlus apps in it, and is South Korean.

i have already got a unlock bootloader code from Huawei's website - Where will ie be used

And the files in Step 1 and 4 are same? and they need to be flashed in Step 1 and 4 together?

Thanks. i am new to Android, so help here would be much appreciated. Thanks.

Hello,

I was able to update from C627B140 to C432B136 without any hassle following this guide. the bootloader has been locked after flashing the B136 firmware again, however, it failed to complete the operation correctly.

Nevertheless, the updates i received include B181 (1.07GB), then B383 (2.02GB, this installed nougat), and currently i am downloading B386(497mb, it has system optimization and android patches).

Thank you to XDA members.

I need oeminfo EVA-L09 C150. Please!!
[Huawei P9 Guides, News, & Discussion] Jekt_:
I had the same problem, after going through the steps and getting past flashing the oem info through TDRP, I was unable to do the dload method again and would get the same message. Also had a Vodafone AUS branded P9.

After going through the updater and ending up on a NRD90 test-keys build by using the official updater with a broken Nougurt install that didn't even have a keyboard. Here is what I did to resolve the problem.

1. Roll back to Android 6 EMUI 4.1

Download official rollback package from Huawei, the rar achive is called:

HUAWEI_P9 _Rollback_Package_EVA-L09_EMUI5.0+Android 7.0 rollback to EMUI4.1+Android 6.0_C900B300.rar

Use dload method to flash the intermediate file in that archive.

2. After reboot build number will no longer be NRD90 test-keys and we can now flash old firmware.

I tried the B136 from this thread at this point and still got the above error so instead I used:

HUAWEI_P9_Firmware_EVA-L09_Andriod 6.0_EMUI 4.1_C432B166_United Kingdom_Channel-Others.zip

Use dload method to flash, after reboot you will be back to Android 6 EMUI 4.1 with build number EVA-L09C432B166

3. Use updater app to upgrade to build B186. Don't need to unlock bootloader or flash the oem file.

4. Do NOT use the updater app to upgrade to the next build otherwise you'll break everything like I did and probably be at the start of these steps again.

Use the Huawei Updater 2.0 method (https://xdaforums.com/showpost.php?p=70594380&postcount=2)

Upgrade to B360 following the steps in that thread. (B361 doesn't work, I got a No internet connection error).

5. Now on B360 and can use updater app to get onto B378.

edit: Updated to B386 from B378 using official updater app no problem.

My Huawei P9 is on the L09C432B386 with twrp-3.1.1-1-eva, rooted as well with FRP and Bootloader unlocked. Maybe I can't do it without wiping data on the phone? I guess something to do with decrypted partitions instead of encrypted?
[Huawei P9 Guides, News, & Discussion] nmd87:
Hi all,

Having successfully performed the steps to successfully change my EE branded P9 to generic C432 I've been on version B182 for the last few weeks. However, I'm now trying to get onto B360/B361 and running into problems.

The first issue is that the updater does not find any new versions and neither does hi suite. The guide in the original post suggests that from C432 B182 an OTA update can be made to B360 but this does not work on my phone; instead the updater says the phone is running the last software.

Therefore, I'm using the firmware finder and Huawei updater methods but neither are able to get me on to B360/B361. Whilst I can download the update and boot into recovery for installation, it always fails with the error Software installed failed! Failed to check the update files. This occurs with either version B360/B361.

I attach some pictures to show the problem. As you can see the update is verified but then fails to install.

Having already tried to clear the cache and a factory reset, I'm now out of ideas. Anyone got any suggestions?

Thanks in advance

Nick
[Huawei P9 Guides, News, & Discussion] zgfg:
If you properly installed stock b182, you would receive OTA upgrades (in that order): b383, b386 and then even (some people receiving) b390 and finally the latest b391

To get each of those OTA upgrades you must keep stock Recovery and stock ROMs, if you install TWRP or root OTAs will sto coming (unlocked bootloader doesn't matter for OTAs)
[Huawei P9 Guides, News, & Discussion] nmd87:
Thanks for the reply. The phone is not rooted and the bootloader is locked (I think) as I got to B182 from B166 via an OTA update. So I presumed that since I got the last update OTA the same should work for B182 onwards...
[Huawei P9 Guides, News, & Discussion] Mostar088:
Somtimes the OTA will get pushed if u do a factory reset.
[Huawei P9 Guides, News, & Discussion] nmd87:

U can if u find a Full OTA firmware from B166.

Would using the MM downgrade package (B136) work?

It should work as long as it is a FULL firmware and not a OTA.
[Huawei P9 Guides, News, & Discussion] nmd87:
Great, thanks. I've successfully got back to B136. Now what to do?

- HiSuite offers an update to EVA-L09C432B182-FULL

- Phone updater app offers an update to EVA-L09C432B166

Not sure which route will allow me to get onto Nougat (if any)?
[Huawei P9 Guides, News, & Discussion] Mostar088:
Not sure, all i know is that u have to be on B182 to go to Nougat. Test one of them. U can allways go back if it does not work.
[Huawei P9 Guides, News, & Discussion] nmd87:
I'm happy to say I finally got onto Nougat. I upgraded to B166 and B182 with the phone updater app. As before there were no updates available in Hisuite or via the phone app. So I again turned to using firmware finder and eventually got onto Nougat by flashing B383 over B182. After that I used FF again to upgrade to B386 and finally B390. Still not getting OTA though.
