[HTC One A9] CSnowRules:
System backups found online can be unreliable for OTA updates. Here's what I suggest:

Install TWRP to your phone, and backup your current boot and system to an external sd. Be sure that the 1.58.709.1 ota.zip is located on your external sd as well.

Extract the system image from 1.56.709.70 RUU, place it on your external sd card as well, and flash it in TWRP.

Reboot to stock recovery and install the 1.58.709.1 ota. It should verify the 1.56.709.70 system and patch it.

That should complete successfully. When it reboots, it will take a long time since it will encrypt data by default.

You will then be 1.58.709.1 stock and be able to take OTA updates.

If something doesn't complete successfully, stop and post the log here.
[HTC One A9] ghasemi.hussein:
Unfortunately the latest ruu for Taiwan is 1.27.709.x for android 6.0.0. I download 1.56.709.70 ota. It doesn't contain system image too. 1.56 was first update if android 6.0.1 and 1.27 was latest build of android 6.0. I think system image of 1.27 is same as 1.5x updates.

I want to try your way in 1.27.
[HTC One A9] CSnowRules:
Ok, that MIGHT work with system images only. 1.2x boot and recovery images will not boot on 1.5x firmware.
[HTC One A9] ghasemi.hussein:
this is what i do step by step:

1. flash twrp

2. backup system and boot partition

3. flash system image from 1.27

4. flash stock recovery

5. try to install 1.56 ota. unsuccessful. see image 1.

6. try to install 1.58 ota. unsuccessful. see image 2.

7. boot to system. it got stuck in bootloop.

8. install twrp and restore system and boot backup.

9. boot to system and it booted successfully.

what else can i do?
[HTC One A9] CSnowRules:
Did you swipe to allow system to be mounted r/w in TWRP? If you did, that could be the problem.

If not, you can attempt to use the system backups that you can download. You may have the same result, though.

Have you tried using HTC sync manager from download mode? Sometimes that will RUU your phone. Your data would be wiped though.
[HTC One A9] ghasemi.hussein:
Yes. I allow twrp to mount system as r/w because without this twrp cannot flash system.img.

I don't understand last paragraph. Will you please explain more?
[HTC One A9] CSnowRules:
TWRP can flash the image without mounting system r/w. That is most likely what is breaking your OTA. Once the system is mounted r/w, it breaks dm-verity, even if you make no modifications.

You should start over and not allow system to be mounted r/w.

HTC sync manager can RUU most modern devices if you connect them in download mode with the software open.

It can be downloaded from HTC's website. I normally wouldn't recommend it since it usually interferes with fastboot and adb if it is installed.
[HTC One A9] ghasemi.hussein:
i try again with system mounted read only. it fail again.

i try htc synce manager in download mode. nothing happen. i'm sure that adb and fastboot are ok because i use them to flash twrp.

i think what would happen if i try 1.27 boot image with system. phone booted well. yes lot's of force close massages come up. in setting it say may build number is 1.27.709.x. i think i downgrade my phone without s-off.

try to use 1.27 zip in stock recovery. it failed. try ota's too with same errors. so it's not a successful downgrade. i just think this info might help someone. going to restore every thing.

just one more thing. after flashing 1.27 boot img, twrp think my internal storage is encrypted.

-----

i'm going to sell this phone and i have to make sure that is can take ota again. what should i do now?
[HTC One A9] CSnowRules:
If you rebooted with the stock boot.img, your internal storage is encrypted.

It isn't a successful downgrade due to the firmware. It will not allow you to downgrade while s-on.

Without an untouched system image or RUU, I'm not sure what to suggest anymore with s-on.

If you intend to sell it, I'd probably s-off and convert to US unlocked. RUU at that point wouldn't be a problem anymore.
[HTC One A9] ghasemi.hussein:
I live in Iran so s-off is not an option for me since I can't use PayPal or other worldwide pay services.

Thank you for all your help.

Update: can I use system partition of other regions?
[HTC One A9] CSnowRules:
I understand.

A system image from other regions would probably boot, but that would not solve the OTA problem.

If you could find a phone repair shop or technician with an xtc2clip, you could s-off that way. They are hard to find, though.

Also, check ir-file.com. they may have the right RUU, but it would cost $30 USD to access it, if you could pay on their site.
[HTC One A9] ghasemi.hussein:
There is a sutible Ruu for me on that site. Pay problem is there too.

Thanks any way. I sell it to my friend and promise to search and solve the problem if it's possible. Maybe in near future someone upload that Ruu from ir-file.com.
[HTC One A9] CSnowRules:
Hopefully someone uploads the Nougat OTA and RUU for your region. That would make things much easier.
[HTC One A9] ghasemi.hussein:
Really??

Could you please post the link?
[HTC One A9] CSnowRules:
Unfortunately I don't have any links. This is purely speculation and wishful thinking.
[HTC One A9] ixxhar:
Need help!

Hi! I am having the same problem, I flashed TWRP for updating phone it was no help. Now I have an ota waiting for downloading which I did 5 times u fortunately failed due to md5 file missing I think TWRP is the problem. Need help to recover to stock recovery. My build is 1.62.161.2. Thanks.

Just FYI, I just got B378 pushed on System Update (was on C432B361 before), if anyone else wants to check for updates. Not sure what changes there are yet, changelog was same as B361, so presumably bug fixes from B360/1
[Huawei P9 Guides, News, & Discussion] icaka20011:
Where are you from? I'm from Bulgaria and I'm running B360.
[Huawei P9 Guides, News, & Discussion] esist:
I was on C432 with B361. It was OTA so might not be a patch for 360 yet.

Hasn't fixed Device Policy anyway ?. Still can't sign into work Google Apps account without complaints that the device is unencrypted.
[Huawei P9 Guides, News, & Discussion] icaka20011:
I'm on C432 too.
[Huawei P9 Guides, News, & Discussion] esist:
As I already said twice: I was on B361.

As someone who flashed it yesterday noted, it includes Duo preinstalled.
[Huawei P9 Guides, News, & Discussion] Clewis94:
Yep just got it myself, check updates :). I'm from UK.
[Huawei P9 Guides, News, & Discussion] Clewis94:
My version info.
[Huawei P9 Guides, News, & Discussion] osrogon:
Did you updated to android 7 from android 6 via OTA? I'm also in UK and I'm still waiting for an OTA (I've been told through HiCare that the latest version for my phone is C432B182 and that they're still working on a version of android 7 for it).

I got my P9 through Amazon and when it arrived, it came with the European version of the charger, not the UK version. Could that be the reason? That even if I'm located in UK, my P9 is not the one officially sold in UK?
[Huawei P9 Guides, News, & Discussion] ylapas:
Here is the official change log for B378:

This update optimizes system performance and stability, and fixes an issue where some UI elements were displayed incorrectly.

[Optimizations]

Decreases power consumption to prolong usage time.

Improves system performance and stability for smoother operations.

Optimizes the display in the status bar and notification panel, which now displays notifications more clearly.

Integrates Google security patches for improved system security.

[Fixes]

Fixes an issue where call durations were not displayed in the call log.

Fixes an issue where some UI elements were displayed incorrectly.
[Huawei P9 Guides, News, & Discussion] clouds5:
Got the notification too.

Since I have TWRP and root what would I have to do to update exactly?

-Flash stock boot.img

-Flash stock recovery

correct?

I'm assuming this doesn't work for a L09C436 phone on B150??

Mine is Voda Australia
[Huawei P9 Guides, News, & Discussion] Brontok:
It only works for EVA-L09C432B182 and/or b360.
[Huawei P9 Guides, News, & Discussion] osrogon:
Did that following the instructions on other thread (I think they are exactly the same you've posted, I'm talking by heart here) and after every finishing Ok and being updated to B361, when the phone rebooted into the new version, the version reported on the about section or the update tool was a test version, not B361. Since that was not what I wanted, I downgraded back to B182.

That's why I was asking if he got the update through OTA.
[Huawei P9 Guides, News, & Discussion] icaka20011:
I updated to B361 from B360 via dload. After that B378 popped up in system update.

After the update everything is working fine.
[Huawei P9 Guides, News, & Discussion] tmohammad:
Were you on the Beta Test Programme?

My P9 which I bought from O2 UK, is not showing any updates. Whether I go thru the EMUI Update or the HiCare App!

So frustrating to find others one or even more versions ahead....
[Huawei P9 Guides, News, & Discussion] dbesoli:
If your P9 is branded then you should wait the O2 updates or better take a look to this manual http://www.htcmania.com/showthread.php?t=1262626 (I don't know if there is some manual in xda in english)

I'm just updating to B378 now
[Huawei P9 Guides, News, & Discussion] Brontok:
[MENTION=849207]osrogon[/MENTION] I know. I found the instructions in one thread and copied them to my pc.. They stayed there for a while since I was afraid to flash anything until I was sure I wont brick the phone :) No idea why it hasnt worked for you.
[Huawei P9 Guides, News, & Discussion] Folgore89:
I got it yesterday OTA on my C432 in Italy.

Anyway, although the changelog mentions battery optimizations, I feel power and memory management is worse than B361. Battery seems to drain faster. Anyone can confirm?
[Huawei P9 Guides, News, & Discussion] icaka20011:
I think after some battery cycles, it will be ok. I hope so. I just updated to B378 in Bulgaria via Software update.

[Huawei P9 Guides, News, & Discussion] tmohammad:
Thanks for that. According to that P9 that has C432 is a European Terminal and hence Unbranded.

Has anyone got a Noughat update in the UK for their P9 which is set to customer "C432" ?
[Huawei P9 Guides, News, & Discussion] Shadowprince94:

[Huawei P9 Guides, News, & Discussion] MartinDimchev:
Woke up today and for 8 hours sleep my phone lost only 1% battery, pretty good, usually it was more than 5% - this is positive! The bad part: Bluetooth was turned ON by itself. Pressed the toggle to turn it off, took about 15 seconds... I had no Data, but the toggle was ON, had to turn it OFF and ON to start working again. HiVoice doesn't work (i don't care about it to be honest).... Not really happy with the update... :)
[Huawei P9 Guides, News, & Discussion] drbazz:
I have a strange situation... I'm from Italy on L09C432B182, and still no OTA for update to Nougat... The only Update I can see is through HiCare (B378)

My phone is debranded and it has the serbian certification (settings->info -> certification).

Do you think I still wait some time to get the OTA or I need to force the update? I regularly updated via OTA my phone from B136 to B182.
[Huawei P9 Guides, News, & Discussion] Gazblade:
Yep, got it a few days ago

Did anyone get it on a c432 L19 yet?
[Huawei P9 Guides, News, & Discussion] clouds5:
Battery life is great so far (2nd cycle on b378). Today I had about 2 hours screen on time and I have 66% left. And that is while using a Wave Unlocker app (using proximity sensor to wake screen).

So I'm happy :) And since I found this modded youtube.apk that allows background playback I don't miss xposed all that much. Only thing that is weird for me are the lockscreen notifications. You can't just pull them down to see their content, you have to pull down the notification bar first? Is that normal behavior? There is even that little arrow thingy which I can't tap when the notification is just on the lockscreen... That's why I'm asking. Hope you guys know what I mean :silly:
[Huawei P9 Guides, News, & Discussion] osrogon:
I'm in UK, I have exactly the same problem with the difference that I don't get any updates in HiCare (been told by Huawei to wait, that the update will eventually appear).
[Huawei P9 Guides, News, & Discussion] ylapas:
L19 is not officially updated to this yet.
[Huawei P9 Guides, News, & Discussion] icaka20011:
Yeah, I have the same problem with the lockscreen notifications. Maybe it's a bug. I hope they fix this and HiVoice in the next update.
[Huawei P9 Guides, News, & Discussion] ylapas:
Well, I did a rollback with my L19C432 with the official files from Huawei for Lithuanian C432. It was successful, rollback was to temporarily version and directly to B182 in the second phase. And HiCare offered official BETA update to B360 here. So back to official BETA channel and every single app now is here and working. Nothing missing, nothing is broken. I'll stay on official untouched BETA now :)

which build were you on and are you unbranded
[Huawei P9 Guides, News, & Discussion] tmohammad:
I think its unbranded?? :confused:

Build EVA-L09C432B182.... purchased from O2 and was already unlocked .

I use a 3 Mobile SIM in the P9.... would that matter?
[Huawei P9 Guides, News, & Discussion] NightOrchid:
If your device is Unbranded, using a different SIM wont make any difference No... Your fine, youll still get all the updates :)

My P9 is also C432B182.. Just dont flash any of these Roms on here... If your P9 is on B182... then its very stable and it runs fine.. wait for B378.. If you start flashing roms.. you can end up messing up your phone and you may end up not being able to get OTA updates at all... :)

Unlike Samsung or LG which have one rom per region which is simple, with Hauwei phones theres a few different versions of the same Rom and you have to know which one to flash .. and its a real pain

Hope that helps :)
[Huawei P9 Guides, News, & Discussion] tmohammad:

Thanks for above.

I have successfully updated to 360. However, when I now try to update to 361 via procedure above, Hisuite downloads the file and at 99% instead of pushing update file to device, throws an error "update failed".

Any idea what may be causing it?

As a side note, I have also tried updating 360 to 361 via Dload. While the update was successful, 360 is still shown in settings. I have wiped partition cache as well but no luck.

thank you
[Huawei P9 Guides, News, & Discussion] NightOrchid:
If its from O2, then when you finished setting up yout phone the first time, you will see a folder on your Home screen with apps such as: O2 Recommends / My O2 / O2 space etc... However, you can also tell by opening up a web browser on your P9 and if it opns the O2 web page.. then yes, your P9 APN is locked to O2 servers.

Dont worry about being with O2 though... since their are more devices sold on contract than unbranded now.... in the last 2 years... Mobile Devs have been pushing updates out to the carriers first and the unbranded get them later... this is because, the carriers buy thousands of devices from the Devs, but the people who buy stock factory devices is very small, so now,... its makes more economic sense to serve carriers first.. In my experience, if you like your updates on time, The worst carrier to buy a contract is EE UK, they take months to release fixes and updates. Im with O2 as well, and theyre pretty good

Hope all that helps :)

[Mogul, XV6800 General] pflatlyne:
I had a problem and I suspected it was due to the updated PRL. The latest ROM update contained 60610 and the one on my phone was 60611. I noticed that the rom updates come with a cab that looks like it updates the PRL. I put the rom on a microsd card and ran it from the phone. It installed the PPST program to my phone. I then went to the windows directory and there was a ppst executable there,along with the PRL file,named 60611.prl . (You will also see this name in the xml file in the cab) I ran PPST,and it installed the PRL and prompted me to reboot. After reboot it reprovisioned the data services and the phone now shows 60611.

Be carefull doing this however,I dont know how to get back to 60611. Presumably sprint can make this happen,but I think they think I have the latest PRL. It prompted me to upgrade the last time I called sprint,so I doubt it will do it again.
