Roll Back to MarshMallow [BLN-L22]

[suhel28]

Hi,

Below are the steps to rollback to Marshmallow from Nougat. I've only tested it on BLN-L22 so I don't know if it works with other variants.

Your bootloader would be locked. However, you can unlock again using the old unlock code.

You can find firmware of your version @ Honor Official Site

1. Download the Marshmallow firmware from here Honor India Official Support
2. Unzip it and place the dload folder in the sdcard (internal storage wont work)
3. Power off the device.
4. Press Volume Down + Volume Up + Power key to log into Huawei software upgrade
5. Let it finish. Now installation is done. But now when you will boot, it will bootloop and go to Huawei ercovery. Simply select the shutdown option
6. Once the device is off, press Volume Up + Power. This will take you to Huawei Recovery
7. Wipe data and Wipe Cache
8. Restart. You are back to MarshMallow

Kindly do the above at your own risk. It worked for me, but it may brick for you.

Edit : User @honor6xak was able to rollback after wiping the system using TWRP and following above steps. If there is no system, there would be no firmware for Honor to overwrite. It would be as good as flashing fresh.


Method 2.

1. Make a nandroid backup (complete backup) and save it somewhere safe. Just in case things get messy.
2. Download the official firmware (Marshmallow) from the Honor official site.
3. Extract the dload folder from the firmware and put it into an sdcard (physical one).
4. Reboot to TWRP and wipe data + system. Twrp will warn you about wiping system. Once you do it. Power off the device.
5. Press volume up + volume down + power this will take you to Huawei recovery and will auto install the firmware if the folder is there in sdcard.

This is a tad bit risky but if you have nandroid backup then you can be on a safe side. But still do it only if you are sure. I don't have money to pay if you Sue me

The above link is for the Indian firmware for the US firmware (L24) you'll have to go to the us website. I got a little confused earlier trying to download it, just thought I'd give a heads up to anybody else. I'd link it but I had to create a new account as my old one is apparrently tied to an email I don't remember.

Yes, that's the reason I specified the BLN number. You don't need to login to have the firmware download. If you can give the link we can update the post.

Edit : I've updated site for Official firmware of various regions in the main post

If you flash these official version you'll get unrooted and your bootloader would be locked again. But you can unlock the bootloader again and root also.

Since it is from official website I doubt it will have any virus

So hacky but... you can find the 'rollback package' here http ://www, hihonor, ]com/us/support/details/index,html?[DOC_ID=94205] and the firmware here http ://www, hihonor, [com/us/support/details/index.html?][DOC_ID=94205]

Just remove the spaces, brackets and replace periods with commas.

Hello bro,

I several times tried the method that you mentioned in your thread using a memory card but it always failed. I'm very curious how it worked for you. Right now I unlocked and rooted my Honor 6x BLN-L22.
I just want to know if your phone was unlocked when you tried this method.
If yes I'll give it a try. It might work this time.
Thank you

Yes, my phone was rooted as well as unlocked when I tried it. I hope it works for you.

Bro it didn't work for me.

 

[suhel28]

Bro it didn't work for me.

You can do one thing I don't know if it work but you can try it. Download firmware finder from play store. Search for the latest nougat firmware then select download. There would be two files 1. Update.zip 2. BLNxxxx some name. Download the second file. Then flash it with twrp.

Now do the procedure as I described in the first post. When I did the roll back I was on the unofficial nougat version.

I'll search for some other method. Sorry it didn't work for you.

It worked for me on my BLN-L24, rolling it back to I could exchange it. However I had to do a couple other steps first to get it to work, so here's my full steps that worked for me:

1. If you have twrp or another custom recovery, flash it back to stock.
1a. To find the stock recovery I had to get it from the zip file here since I'm a dumbass and didn't make a backup: If you have twrp or another custom recovery, flash it back to stock.
2. If you have a custom bootloader, flash it back to stock.
3. Download and extract the stock rom. Flashing it from zip will not work.
4. Copy the UPDATE.app to /sdcard/dload/ (not a physical sdcard, if that's what's confusing you.
5. Turn the device all the way off.
6. Press and hold volume up, and volume down, then press and hold power until the phone starts booting, immediately release it once you see something on the screen.

It should now 'update' your phone back to EMUI 4.1.

I'd put the dload folder in the sdcard folder but it didn't work. I'd to use a physical sdcard

What did you do that you are stuck at TWRP?
Tell the history then we can suggest something

Download the update_data_full_BLN-L22_channel_in.zip and place it on sdcard.

You can then flash it with TWRP

 

[honor6xak]

You cannot directly flash the 4.1 file on your nougat. If you want to do that then you have to use the procedure I gave in the first page.

The link I gave is for nougat version. Basically, when I had a similar problem like you I flashed the 733mb file and my phone was able to boot.

Wipe data in TWRP
Flash the 733mb file
Wipe cache

I hope it works

Both methods didn't work for me though I flashed the 733mb file using TWRP successfully.
