[Honor 6, 6 Plus General] RomanosN:
Update Methods and other information

0. Official Update Channels from Huawei

Before you start updating your favorite Honor 6 through OTA, Local Update (LU) or with The 3 Buttons (3B) method you have to understand what kind of ROM you have to download and update to.

The official channels from Huawei are currently only two, which makes the things easier.

The first one is the beta/dev channel. This channel usually includes new features and bug fixes that have yet to arrive at the stable ROM or they won't arrive at all.

The second one is the so-called "stable". It's usually polished and as possible as it can be bug free. If you don't know what ROM to Download use this channel.

An easy way to distinguish these two ROMs is the following.

1. Go to Settings

2. About phone

3. Build Number

There you will find a complex string that contains letters and numbers. You have to look for the last four or more characters. The chances are that the last 3 characters will be in the form of BXXX, where XXX are numbers. If it is in a form of B6XX or 4.XX.YY where XX is the month and YY are the day, on which, this ROM released, then you are on the beta channel. If the string is in a form of B3XX then you are in the stable channel. The last four or more characters may change in the future, please ask any active user, to guide you through, if you don't know in which channel you are on.

Before you start any update procedure please be sure that you have at least 33% of battery and you have a copy(backup) of your files.

---------------------------------------------------------------------

To update a Honor 6 there are two, plus one, methods. The one is through the so-called OTA (Over The Air) without the need to connect the smartphone to the computer. The other one is the classical one, that you have to download the ROM on your PC and then copy it, on the memory of your phone or in a removable disk (USB STICK).

1. OTA

The update through OTA, is the easiest, fastest and the most "bloodless". Depending on the update channel that you already present (read above), you will get the same channel update. Explaining a little bit further, if you are on the beta channel you will get the updates of the beta channel, if you are on the stable channel you will get the stable channel updates, there are no crossovers between OTAs*.

*There is only one situation, at the moment, when using a beta version you will end up, in the future (after several updates) updating to the stable channel. This is when Huawei will test a new version of EMUI. In more detail, when Huawei was testing the early versions of EMUI 3.0, it was basically a beta channel for this specific version. This beta channel, as it was an ongoing project, after several updates and due to the project's maturation, it resulted in the first stable version of EMUI 3.0, also known as version B307. After that, Huawei, again splitted the stable channel, in a new beta channel with 4.XX.YY codename and a new stable channel with code B3XX as described above.

1. Go to the Settings

2. Updater (second choice from the last)

3. And tap Check for updates

When you will do the third step (and there is an update to be done by Huawei) there will pop up a message and a wizard will guide you through the update process. When the download of the OTA get finished, the Honor 6 will restart itself, get into recovery and install the update, after all it will return to your home screen with the new update installed.

----------------------------------------------------------------------------------------

2. Local Update (LU) or Update via USB drive (USB)

Before we continue explaining the Local Update procedure, let's distinguish the differences between Local Update and Update via USB drive options.

In order for the LU method to be completed, the file must reside in the memory of the mobile phone or microSD card. While on the USB method, the file must be in a removable disk (USB STICK) and be connected through USB OTG cable to Honor 6.

Usually because of the it's easiness the LU method is preferred.

1. Download the ROM from the official site of Huawei (See here) with the help of a Download Manager, like Free Download Manager in order to have better speed and an error free file.

2. The file that you have downloaded it's a zip file which contains a dload folder and a PDF file with a guide. The guide in the PDF is in Chinese, so it's not usable for the most of us here.

3. Extract the zip file wherever you feel like in your PC.

4. Copy the dload folder on the microSD card for the LU method or in a USB stick for the USB method. Before you do so, for the USB Method, please be sure that the USB stick is empty and formatted to FAT32. If dload folder is already present in either of the two methods, delete it.

5. Go to Settings ---> Updater ---> Menu (3 stripes in the bottom) ---> Choose either Local Update or Update via USB, depending on your choice above.

After the selection, the phone will reboot itself and will continue with the update procedure as described in the OTA method.

The OTA, LU and USB methods are not deleting your files, but it is highly recommended to take a backup of all your files before you start any update procedure.

--------------------------------------------------------------------------

3. Update through the 3 Buttons (3B)

Last but not least, there is an option to update with the 3 buttons. The so-called three buttons are, the Power On/Off + Volume Up + Volume Down. The method to update with the 3B are the same as the LU but the update procedure changes a little bit.

1. Follow the LU method until step 4 (you do step 4).

2. Turn off the Honor 6.

3. After the shutdown is complete, press the buttons I described above and hold them until the update procedure is started.

Be aware that this update procedures will delete everything in the Honor's 6 memory (not the microSD Card) so if you have any files in there, take a backup of them.

-------------------------------------------------------------------------------------------

4. Update through Leaked OTAs/ROMs

Attention!The following procedure is to be followed, only and only when, it is well written that the file that you have downloaded is a leaked one. If it is not, then please follow guides 1,2,3 as described above.

Moreover, the following procedure is to be followed, if not any other guide has been given with the leaked material.

Last but not least, the following guide is based on a leaked material inside a zip file. If you don't know what you are trying to do, please ask for more information or a confirmation that this particular method will work.

1. Download the zip* file.

2. Rename it to update.zip

3. Copy the update.zip file, to the dload folder (if there is none, create it. If there is already one present, delete it)

4. Follow the LU method from step 5 and beyond.

The zip file must contain folders, META-INF, patch, system and the file UPDATE.APP. There is a chance it may contain more or less files and folders depending on the leaked material. If the zip does not contain this folder, but there is another zip inside the first one, that contains this folder, then extract the second zip and follow the above procedure.

-------------------------------------------------------------------------------------------

Other Information

If anything goes wrong with the update, you can always check the update log. First of all you will need a File Explorer that is capable of showing the folder that needs to be accessed. I have already tested ES Explorer and works great, other File Explorers may work too. As [MENTION=4420962]chrissss91[/MENTION] told me, the update log can be found at /splash2/recovery_log , feel free to thank him :)
