Security Error and Network Lock

A few days after updating my phone to Nougat, my phone restarted itself, and after the restart, a security error showed up saying "This phone has been flashed with unauthorized software and is locked", and after unlocking the phone a screen came up saying that my device has been network locked and it can be unlocked using the device unlock app, and the invalid sim card error.
I was never rooted or anything like that, my phone had received OTA updates. I did not master reset, but I rebooted many times, and the error message appeared on every boot, but disappeared after a while allowing me to use my phone. And now, although the error doesn't seem to appear anymore, i still can't use my network, and when I checked the IMEI, it had changed to 350000000000006, and the one on the back is different.
Is there any possible way to fix this without sending this phone back to Samsung/T-Mobile for exchange, because I had bought this phone from USA but brought it to Pakistan, and Samsung Pakistan says that they would charge me for the repairs ( I still haven't visited them, they told this to me through mail).
HELP PLEASE?

Bump?

Have you tried using Samsung Smart Switch?

I didn't try Samsung Smart Switch, but I had reflashed it using Odin, and tried a factory reset and it didn't fix it, i got it fixed through Z3X box.

This happened to me also.

I had taken in to a repair shop who had a Z3X box. That's the only way to get it fixed. He downgraded my phone to Marshmallow and re-flashed the cert. I live in Pakistan and that costed my Rs.1000 (i.e. $10). Make sure you take your phone's box with you as a proof of purchase because changing IMEIs is illegal in many places.
P.S. I can't upgrade to Nougat now, if I will, the phone won't register to the network.

Thanks mate. I also live in Pakistan - Lahore. I took my phone to Hafeez center and they charged me 1500. Now the phone is on Marshmallow. I'm receiving notification of update. I've tried 3 times but if failed to install. When I tap on update it downloads the OS which is about 1.3GB. then restarts to install but it fails when reaches 30%.
Can you please tell me why we can't update our phones. I'm using another s6 which is also of T-mobile and it's running fine on nougat.

Not sure about that but we can't update because probably our CERT files have been patched in EFS is messed, I got it done back in July 2017, and at that time, the guy who repaired it said that they didn't have Z3X's software update for Nougat, so they had to downgrade my phone to Marshmallow, and the patch they used won't work on Nougat. Don't know about yours though, maybe he used an updated patch or a different tool, you can ask that guy whether if its safe for you to update to Nougat or not, if he allows it, then try flashing Nougat through Odin, if it doesn't work you'll have to get it patched by him again. Don't update if he doesn't allow, otherwise he won't patch it again without extra charges, and if he allows that and something goes wrong you can blame him for that

Simple UPDATE of EVA-L19C636B190 to Nougat FAILED

Hello guys,
I have failed. And now I do not know how to continue.
My tragic storry: I wanted to update my HUAWEI P9 from Marshmallow to Nougat and got an error during update, because I am an idiot. I took an (wrong) update from some site, putted it in a dload folder on a sd card and started the update. The update started, the phone rebooted and continued. But at 5% comes "Software update failed! Incompatibulity with current version. Please download the correct update package."
After that I started to search for a solution.
Now I found this site and it seems that here are a lot of people, that are able to solve such problems between wakeup and teeth brushing. I hope someone here can help me with good advices, which avoid me of damaging my phone completely and bring me instead on the way that I can solve my problem.
Enough of the chatter, this is my current knowledge (correct me if I am wrong):
I have (had) a P9 with EVA-L19C636B190 Firmware. (I have noted this before update)
L19 stands for the dual sim P9.
C636 is the Asia/Pacific Hardware
B190 was the old version of stock Android (Marshmallow)
(I know now, that I have tooked the wrong Hardware-Package. I should have taken C636 and
everything would have become beautiful)
As I understand, the wrong Firmware is now on my phone and the bootloader try to continue the update each time I start an Update.
If I start the phone normaly, I get the EMUI logo with the options to "Download latest version and recovery" (No way, with the wifi connection, he can not find a server to download), "Reboot" and "Shutdown".
I suppose, that there is a partition on my phone, where the wrong update file was loaded to. Because if I try to "update" back to EVA-L19C636B190, there is no difference, the update ends at 5%, even without a sd card. So I think, that I need to clear this partition and need to start an update with the dload-folder-method again.
As I understand some artikles here, I need for that a special tool (SRK), with which I can clear the partition in the FASTBOOT&RESCUE MODE. But for that the phone must be unlocked.
In next step I need to unlock the boatloader with the huawei online tool where i get the unlock code based on my serial number and so on.
What would you say to my plan? Or is there an easier method?
What do I need for that?
Please be indulgent with me, I try to learn and to undestand to solve my problem
Thank you in advance.

Huawei p9 Korea (L09) - how to go back to stock?

I'm in Korea and bought a P9 (L09-for Korean market).
I was so frustrated cause it stucked on android M (Huawei Korea didnt even care to give it an upgrade to android N) I tried to do it on my own. I followed a number of instructions here on XDA which I had no idea what they are about and whether I did the right thing, I basically unlocked bootloader, debranded the phone, installed custom TWRP and nougat packages. As a result I got android N (B386 probably) on my phone, no keyboard, no fingerprint, and no service when inserting sim. Is my phone bricked? How do I fix it or make it go back to stock android M.

Your phone is not bricked since it still boots...
If you want a keyboard, download the google keyboard apk, transfer it to your phone and install it in file manager.

To rollback to mm, flash this using dload: https://forum.xda-developers.com/p9/how-to/rollback-eva-l19-android-7-0-emui-5-0-t3496091

Updating to Oreo not working

Hi everyone
So , I know there is a lot of threads about that question but I can't find the right thing to do. I bought a not much used P10 few months ago and I know nearly nothing about it apart from the fact that it has been rebranded I think . I have no experience in manual updates and apart from the B171 it downloaded first time I got it , I didn't receive any OTA update. I tried Frimware finder both DNS and proxy and none of them worked . Now iam trying to download the whole B365 and then using proxy method , I read that on AndroidPit . any suggestions ?
Ps: for some reason my IMEI is a series of 00000000 while the "MEID" is normal

What model do you have and which version is installed?
The IMEI is a hardware specific number. If Android shows only zeros either your hardware is faulty or EMUI isn't installed correctly.
So, before you try to update do a complete factory reset within Huawei eRecovery. For this, restart your phone while it's connected to USB and holding Vol+. Then tap on factory reset - Note that all your data on internal memory will be removed.
After this factory reset look again at the IMEI.
Are you able to contact the seller for rebranding information (which model is this phone originally?)?.

Thanks for the reply , Android shows me L29 model but on the back of the phone it is written L09, I have no contact with the seller but i do think it was to enable the dual SIM function since it is unavailable on L09 the software version is VTR-L29C432B171 and is there a way to save the data before the recovery ?

Oh and , if a do a complete factory reset , will this remove the rebranding ?

No, and the branding shouldn't be the issue if it's just a rebrand from L09C432 to L29C432, I did the same without any problems.
You can backup your data with HiSuite App for PC or with a SD card and the backup App on the phone.
But you have to backup your camera folder (DCIM) manually, HiSuite won't backup Photos, also no Pictures, Videos or other Media. It works good for contacts, SMS, Phone settings and Apps including settings.
Is your phones bootloader unlocked?
The missing IMEI CNA be the reason why you won't get any official updates and FF doesn't work.
If you are unlocked you can use my guide (Tutorial #1) to update your phone manually.
If your bootloader is locked and you don't have the unlock code it's not possible to unlock it without the pay-tool DC Phoenix. Huawei stopped providing bootloader codes one month ago.
If you have the code and you want to unlock notice, that an unlock will cause a factory reset!

According to Huawei, bootloader unlock codes would be provided until 60 days after 24 May. So if you apply for it today, you may be lucky. More info: https://www.androidpolice.com/2018/05/24/huawei-halts-bootloader-unlock-program-indefinitely/

Need to return P9 back to L09C432B504 from c900b300

Hello everyone !
I had a battery drain issue so I wanted to try and change the software before resorting to a battery change, but now my phone is stuck at L09 C900B300 build and it used to be factory L09C432B504. I tried downloading the full package for 501 but the phone does not want to install it as it was "invalid".
Any ideas how I can force the b501 update on the phone ? It's hard to use ADB since the USB-C port on the phone is very worn out and it only maintains data-transfer in a certain position, if it gets shifted even a little bit it breaks the connection.
Thanks in advance !

You did a rollback and you cannot instal Nougat directly back
You must install c432b182 Marshmallow and then let it update by OTAs (with SIM card) to b50x
https://forum.xda-developers.com/showpost.php?p=73131443&postcount=321
Steps 4-9 apply to you (since you are already on c900b300)
---
Don't know what does it mean to you that you changed the software
If you rebranded from c432 to another cust, then you must also rebrand back to c432 by flashing its OEMINFO:

NOTE: Just saw you previously asked questions about P9 Lite
Pls be aware, this is Huawei P9 subforum, not for P9 Lite (different hardware, different firmwares)
The answer above with links/guides applies to P9, not to P9 Lite
If your question was for P9 Lite, please better search and ask on XDA P9 Lite subforum

Hey !
Thanks for your reply.
I have tried to follow the steps but I need to have the bootloader unlocked and it is discontinued by huawei, and in order to get the code from DC unlocker I need to invest a certain amount of money (id rather hand the phone over to a professional service and pay them and know that I have a fixed phone).
The other issue of the phone is that I cannot open the manufacturer mode on the phone using *#*#2846579#*#* since it does nothing, and I cannot use the calculator since this software does not have a calculator, it doesn't even have a camera app....
So I have contacted huawei support in hopes of getting the bootloader code but I do not hope for too much at this point. What are my other options at this point of handling this on my own ?
Looking forward to your response !

AFAIK, 'certain amount of money' for Bootloader code from DC Unlocker is only 4 Euros
If you search on XDA (various phones, just about Bootloader unlocking) you may find more online services (several months ago I've seen in some post), but they were more expensive
IMO, you don't need unlocked Bootloader if you are just following the first link, for dload-ing c432b182 without flashing oeminfo....

Update:
Okay the b182 package does not require unlocked bootloader which is great, it took the update and started going up all the way to b395 but it stopped there, no further OTA updates... It is okay to use at this point but I'm still curious to know if there is a way to get to it to update to the b50x version. I did try to use the small update for the b501 but the phone declined it.
Still thank you very much for guiding me through this ! This is a huge weight off my shoulders !

In Firmware Finder they have a new method based on eRecovery and changing the DNS server on your local WLAN AP
b50x must be showing as Approved to you for that method
It does not require Bootloader unlocked but no guarantee it would work (I tried with P9 rebranded to AL10 Oreo, managed to change DNS server address, eRecovery connected to but failed to update firmware that way)
There HWOTA method (in few variants) to install FullOTA-MF from Firmware Finder, but unlocked Bootloader is required
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
Btw, if you ever unlocked Bootloader on that phone, just use the same code again (one must save always save the code for future needs)
As of recently there are some Huawei service firmware installations available, that also install by dload (not needed to have Bootloader unlocked)

When you download, you will need to unzip
Find Docs and Software subfolders (you may need to untar and unzip Software subfolder again)
In Docs folder there must be Huawei official guide how to install, check if it describes dload method (and what must be un-archived and copied to SD card dload folder from the Software subfloder)
I didn't use it for L09c432 but I successfully unbricked a P9 rebranded to AL10c00 (back to AL10c00 firmware) by such a package, really easy by dload, just by following their HowTo doc from the Docs subfolder
