You have to flash B316 stock rom and stock recovery in order to be able to upgrade. Not from OTA, you need to flash full stable rom.
Then put the zip file in sdcard/dload folder. You can also put it in root of your sdcard.
Power off your phone and then press VolumeUP (+), VolumeDown(-) and power button, release them as soon as the Honor Logo appears.
The software installation process will start.
WARNING: This is not a stable version of EMUI so you should also have the rollback file in order to downgrade if necessary. The first beta version of EMUI 3.1 is B505 for H60-L02. If you are willing to upgrade to B506, the second version of beta EMUI3.1, proceed with caution. The rollback zip for L02 version is not available yet, so do NOT try to downgrade.

This only guide you to upgrade and Downgrade your device from kitkat, lollipop and marshmallow within stock recovery.
First of all there is a master package called Bypass(CHC-U03) thats works on any version of Kitkat and Lollipop. On Marshmallow it doesn't work. There is a seperate package downgrade pack for marsmallow available.
As we know there are 2 Variants available -
1. Honor 4C (CHM -U01)
2. Huawei G Play Mini (CHC-U01)
They both are based on same config just the build no. Is different. But the process for installing rom is same. If your device is Honor 4C you will chose CHM Pack and if yours is G Play mini chose CHC pack. All upgrade and Downgrade package is available on Huawei official site.
### How to install Full update package ###
Full update package is available as UPDATE.APP and could be found after extracting from update package zip file.
Installing process :
1. Extract the zip.
2. Copy the folder dload(that contains a UPDATE.APP inside) on sd card.
3. Update using local update from updater or using force update (power off the device and then press power + vol+ + vol- at together until huawei or honor logo appers) or using dial method (dial *#*#2846579#*#* and select software upgrade)
4. After finishing the update process the device will restart automatically and then you are done.

2. Then install your desired CHM rom.

Upgrading or downgrading will remove all of your data located on internal storage. But there is a way that should work!
Use Huawei's official backup app : https://play.google.com/store/apps/details?id=com.huawei.KoBackup
Than after creating a backup file you are ok to go forword to downgrade. The thread need some update as there are some new firmwares available. If you are CHM User then Your kitkat version is CHM B190 and for CHC it's CHC B182.
All Upate for
HONOR 4C (CHM -U01) -

Problem installing twrp

Hi hope someone can help me, ive been tryin to install twrp on my honor l09,i followed every step on the tut to install twrp, but when i reboot to recovery it will just stuck on "your device has been unlocked and can't be trusted".. :crying:
Hi, you need to flash a correct twrp version, which will work for your phone model & android version installed.
Android 6.0 ("marshmallow") Honor 8 twrp version: 3.0.2 -> https://eu.dl.twrp.me/frd/twrp-3.0.2-0-frd.img
Android 7.0 ("nougat") Honor 8 twrp version: 3.1.1 -> https://eu.dl.twrp.me/frd/twrp-3.1.1-0-frd.img
Android 8.0 ("oreo") Honor 8 twrp version: 3.2.1 (oreo compatible version, should work for android 7.0 too)-> https://eu.dl.twrp.me/frd/twrp-3.2.1-0-frd.img
If it's not working, you can find and flash modded twrp version with "Huawei Multi-Tool by Team MT v8": https://forum.xda-developers.com/honor-8/development/tool-huawei-multi-tool-team-mt-t3523923 (Working download link on last comments page)

Honor 8 , no way to enter recovery TWRP

Hello, i have a Honor 8 where i had installed TWRP 3.1.1-1 and Resurrection Remix N v5.8.4 . With that rom i was not able to use Usb so i installed on it AOSPA 7.1.2.
Doing that i lost the root (prolly i did something wrong) and i was not able to get it back so i tried to rollback to FRD-L09c432b131 installing first Honor 8_Rollback Package_FRD-L19_from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1_C900B300_Italian and after it installing Honor 8_Firmware_FRD-L09_Android 6.0_EMUI 4.1_C432B131_Western Europe . Now my phone is on FRD-L09C432b131 and it is working without problem but i can't find a way to update the firmware with original roms (tried multiple time with different packages without luck) or to install again Resurrection Remix N v5.8.4 because i'm not able to boot in TWRP even if the installation process of the recovery doesn't give error.
To be sure i also used the Unbrick function of Multi - tool extracting the required file with Huawei Update Extractor from the Update.app file of Honor 8_Firmware_FRD-L09_Android 6.0_EMUI 4.1_C432B131_Western Europe but still i can't find a way to get back to TWRP recovery or to install any original firmware update.
If anyone have any idea about why i would be happy to get some help
