I recently tried to update my P9 to Android 7 using a tutorial from HTC Mania which has worked for many people on that forum. The phone was branded (Movistar, Spain). After following all the steps I ended up with a de-branded phone but it was still EMUI 4.1.1 Marshmallow. It says I have HW EU but the Kernel is: C900B181 Build No: EVA-L09C432B181.* Where have I gone wrong.* I was advised to post the question here by HTC Mania (KrAzYtHeBoY). Vendor info states: Vendor and country file does not exist. Any help would be appreciated.
Vendor info states: Vendor and country file does not exist.
For the above. Did you flash the c432oeminfo.zip(spelt something like that) in recovery? If not then the custid is probably mismatching with the firmware causing a number of software related issues.
Yes. Here are the steps I followed after unlocking the bootloader and installing TWRP. It's a translation from Spanish but in think you'll get the gist.
1. we will need unlocked Bootloader, TWRP Custom Recovery and be in Android 6.0
2. Download oeminfo_c432.zip and copy the .zip to the phone's internal memory
3. Download the official Firmware C432B136 extract the "dload" folder and copy it to the microSD external memory (memory is not worth)
4. We turn off the phone and disconnect the USB cable
5. Turn on by pressing and holding "POWER" + "Volume up" when you leave the logo Huawei release "POWER" and keep "Volume up" until the logo 'TWRP-Team Win'
6. Touch "Install" and select the file "oeminfo_c432.zip" zip and slide for flashing.
7. If everything is OK and not given any error we will continue.
8. let TWRP main menu and touch in "Reboot > Power OFF" to turn off the terminal
9. With the terminal off, press all at the same time "volume up" + "Volume down" + "Power" until that is installing the firmware (and we can now release the buttons)
* we will see a screen with red letters warning, not do case and keep the keys, volume up and volume down until you see the screen "EMUI" installing the update.
10. correct once the installation will proceed to update to the C432B182
starting we will ask to do a "Factory Reset", we do "Factory Reset" and turn on the phone.
To know that CUST is the correct open Phone Dialer and mark: * #* #2846579 #* #*
should appear: Vendor: hw / Country: Eu
Note: to flashing official firmware of Huawei the BOOTLOADER will be blocked and the TWRP is lost. (go to the developer options and disable "enable OEM unlock" so that all this 100% of manufactures.
I should also say that after I had finished it did show Vendor: HW/Country: EU but after doing a factory reset the phone seemed to be bricked, being in a loop where I was asked to enter my password to decrypt the phone and it just kept saying 'Decryption unsuccessful. Eventually after trying different button press combinations I got the phone to boot. Also, what is B181, I can't find any mention of that build anywhere?. Do I need to start again from the beginning? I new to all this so thank you for your patience.

Thanks. My phone was de-branded when used the tutorial from HTC Mania, but presumable it won't hurt to follow your recommendation from the beginning? Also fastboot states that the bootloader is unlocked but you think it may be locked from when I flashed the incorrect firmware?
Hello everyone,
I bought a few days ago the Honor 5C and decided to root it. So I installed the TWRP (Nemo) using "fastboot", downloaded a ZIP of SuperSU and placed at the root of the internal storage. But when I try to enter recovery mode by using "adb reboot recovery" or by pressing the Volume Up + Power buttons, the phone vibrates, displays nothing for 2-3 seconds (not even a black screen, the screen is completely off). After that the "Honor" logo is dispayed for less than a second then the screen "Your device has been unlocked and can't be trusted [...] Your device is booting now..." with no option at all.
The problem is that this screen stays forever and never displays the recovery mode screen. If I entered this mode using the physical buttons, I can just press "Power" for a few seconds and then it reboots the phone normally. But if I used "adb", each reboot makes the phone entering again the same recovery mode that doesn't work, so I use the Volume Up + Power key while the phone is connected via USB to my laptop to enter e-recovery mode, then reboot normally.
Does anyone know how to solve this problem ? I really want to root my phone but I don't know what to do for now.
Thanks by advance for your answers !

Are you on EMUI 5 (Android Nougat) ? If so, official TWRP is not compatible with version > EMUI 4.x for now.
I'm using EMUI 5.0 / Android 7.0.
So now I've installed an incompatible TWRP can I just downgrade to EMUI 4.0 / Android 5.0 then flash it again and root my phone or should I reflash the original recovery before doing that ? I've read somewhere that updating a rooted phone could brick it so even if mine has just a TWRP and want to downgrade instead of upgrading I prefer to be sure.
Thanks by advance !

you need install original recovery and extract update.app from B100 firmware, then you place it to "dload" folder in your sd card and flash using 3 buttons. you cant full brick by messing with root. only soft brick which is fixable.
Ok I'll try it. I will post again if something comes wrong.
Thanks a lot for your help
I forgot to ask about one thing : I'm owning a phone with NEM-L51 model and I don't know if I can use NEM-L22 firmware ? If I can't, where can I find the right files to downgrade this specific model ? All the firmware files I see on the web are for the NEM-L22...
EDIT : I've found the B102 firmware for NEM-L51 model (Europe + UK) can I take it for the downgrade or is the B100 specific version needed ?

Thanks for your help but this doesn't work. When I do what you say it goes again and again to the same warning screen which never disappears. This is really strange, when I see videos I find on YouTube all Honor 5C owners that just do what you say enter in recovery mode, but it's not my case... I really wonder why.
I don't know if that can help you to understand, but I'm using a french Honor 5C phone, with EMUI 5.0 / Android Nougat like I said previously, model is NEM-L51 and I did the Android Nougat update several days ago using the Honor's official update application, which is natively installed on the phone.
About the firmwares, I've tried the B102 version for the specific model I own but each time (I downloaded the update ZIP several times, the first one with two folders named '1-main' and '2-vendor', the second with just the 'dload' files) the update stops at 5 purcents and says "Software install failed! Incompatibility with current version. Please download the correct update package."
What can I do to solve this problem ?

When you do Volume Up + Power it attemps to enter recovery mode, not recovery (that's what I read), excepted if a USB cable is plugged in (which is not my case). And that still doesn't work.
However, I'm able to enter erecovery mode by turning on the phone with only the Power button, then holding "Volume Up" as written on the screen (there are 3 boot options that shows up, but only when I boot normally) and I enter erecovery mode. But I can't do anything interesting in this mode, just download the latest firmware (which fails at each attempt, even when I'm connected to a working WiFi point), shutdown or reboot the phone normally.
Shoud I show you a video of when I boot my phone in normal mode / recovery mode / erecovery mode ?

The problem is that I can't enter recovery mode, each time I try to install an OTA or full update package from the /dload folder on the SD card it fails, so I can't downgrade at all. Do you know a link that sure points to the good update package version for the Honor 5C on EMUI 5.0 in order to downgrade to Marshmallow ? I've found several links during my searches but I don't know if the installation fails because of a phone's bug or if it fails because of an invalid version.
EDIT : I forgot to precise the long model name of my phone : NEM-L51C432B350. On Firmware Finder Rewrite it shows that there are only two update packages for it, published on 20.04.2017... So I wonder if I need to download the three files shown in the filelist of the big update (1.68 Gb) and install them on the device ?

Stock recovery wont have an option . There is no graphical UI for installation.
Downgrade or update is just a manual procedure.
In order to roll back , u need to install a roll back package and then the origional MM package . Using the three button combination

Ok so in the guide I found on the same page I linked in my previous post (the guide is hopefully written in english) it says that the phone must haven't been rooted or even unlocked, so I prefered to relock the bootloader (and completely reset my phone, for the third time at least in two days).
But then I realized I would need to have an unlocked bootloader for the flash so I unlocked it again, but now the device stucks on "Your device is booting now..." with no option at all whatever I do, whatever the buttons I push... I'll really start to think I'm simply idiot
I'm searching on how to solve this new problem and unbrick the phone... 'cause I can't even shutdown it, the "Volume Up + Power" combination while USB plugged in or anything else doesn't work this time.
EDIT : Okay so my phone seems to really be hard-bricked. My phone just stays at the screen "Your device is booting now..." with no option at all, I can't shutdown it, I can't enter recovery or erecovery mode. Does anyone know what to do or is my phone definitively bricked ?

Nope, long click of power button will just reboot the phone and make it displaying the same screen again and again.... I can't shutdown it at all. I've tried several times but it doesn't work :crying:

But how can I unbrick the phone ? I can't enter in any mode, I can't connect it to PC, I can't shutdown the phone, I can't use ADB or FastBoot on it, I can't reflash the bootloader or install a TWRP, downgrade or boot normally, I can't do anything !
So how could I unbrick it ? For now it's just still displaying "Your device is booting now..."
If you know how to do, please tell me so I can unbrick my phone. Sorry for asking you so many things I don't understand myself why there are so many problems...
Hi guys,
My firmware is stuck on emui 4.1 and I'm trying to install a custom Rom.
Bootloader unlocked fine
adb worked fine
I've flashed twrp
However, whenever I try to reboot I get the "your phone can't be trusted" boot recovery screen instead of TWRP, so I can't root.
I've tried power and up, power and down, and power and up and down.
They either go to the recovery option screen, then boot like normal, or hangs on the normal boot screen
Any suggestions
Things repeated several times elswhere.
1. Your phone cannot be trusted because you unlocked the bootloader. If you don't like it, re-lock bootloader ;-(
2. Upon flashing TWRP, FIRST THING YOU MUST DO is rebooting to TWRP. If you don't do that, stock Recovery will ovewrite TWRP.
Find instructions in the TWRP threads how to enforce immediate booting to TWRP, upon you flashed it:
-Type on the PC: fastboot reboot -but don't press Enter yet.
-Press and keep pressing Vol+ and Power buttons together on the phone
-Press Enter on the PC and then immediately unplug USB cabel.
-When phone shows Booting, release Power but keep pressing Vol+. button
