My device is European L04, currently running North Africa release (the earliest Marshmallow build uploaded) - L04_2016_0316_0900 (B820)
I'd like to unlock the bootloader and root my Honor 6. I've never done it (on this particular device), because I've read enough here to know it's slightly more risky than on other devices, especially when you plan to update the stock rom soon, so I preferred to wait until I have the last important update the device is likely to receive - Android 6.0.
What I want to know (some of the answers are in the topics which I listed below):
MultiTool - I've seen reports of bricks when using MultiTool with EMUI4/Marshmallow - why does it happen? My understanding is that MultiTool is a bundle of adb/fastboot and some recovery images for older Android versions, so my theory is that instead of using MultiTool, I should simply get the proper recovery for Marshmallow and flash it manually with fastboot, right?
unlocking bootloader, rooting, flashing recovery - I think I understand the process; in a nutshell: 'fastboot oem unlock X', 'fastboot flash recovery imagename.img', then flash the proper SU.zip in recovery. Where do I find the code, the Marshmallow recovery image, the SU.zip file?
will recovery backup in TWRP work without any problems?
what is the procedure to go back to stock completely after rooting? Unroot, (then wipe if it's needed?) so I am able to safely flash stock firmware again (since, from what I know, flashing stock on a rooted phone makes itself brick permanently, right? or is it just a soft-brick and it can be fixed?)
is there anything else I should know before proceeding?
What I found so far:
http://forum.xda-developers.com/showpost.php?p=66615082&postcount=502 - two recovery images, TWRP and another one (stock?) for the Marshmallow release
http://forum.xda-developers.com/honor-6/general/honor6-multi-tool-t2963060/page50 some rooting instructions for the L02 beta, see posts 494 and 498; no idea whether this is applicable to final Marshmallow or L04 at all
http://forum.xda-developers.com/honor-6/general/huawei-honor-6-plus-unlock-bootloader-id-t3357259 an app to get the unlock code, seems a bit shady to me though on the first glance
http://forum.xda-developers.com/honor-6/development/honor-6-rooting-method-t2962795 alternate methods for bootloader (through a website or by email), in case the app won't work; also, detailed instructions on unlocking and rooting
Basically, I need to know whether my procedure is more or less right before I proceed. I think the information is quite hard to find and the risks are quite high, so I'd like to make a promise - when I'm done rooting it and I know the correct process, I'm going to make a "Update to Marshmallow, unlock, root" how-to thread for all the people that will need it in the future.
Another two questions...
1. Where do I get proper SuperSU for Marshmallow? I get a boot loop (yeah, I know I have to wait and I did, but it's a pretty obvious bootloop from watching the logcat content, and nothing new happens...) after flashing http://download.chainfire.eu/supersu-stable (2.65).
2. I have unlocked my bootloader and installed TWRP, so recovery and fastboot are functional. I didn't make a backup before flashing the zip and now I'm in a bootloop. How do I restore working Marshmallow? I assume I can either beg somebody to upload a TWRP backup for my H60-L04, or somehow flash the stock over what I have now. Can I simply use manual update from SD? Can I somehow flash Marshmallow again with fastboot? I'm too scared of bricking my device right now so I guess I'll brace myself for a few days without a phone until somebody helps me :/
I just flashed the Marshmallow release I had before the bootloop (I used Huawei Update Extractor and flashed boot, cust, system and recovery with fastboot; then open up Huawei recovery and factory reset for good measure, I'm not sure it was even needed) and the device is working. I'll restore my stuff, install TWRP, make a backup then try out your ZIP. Thanks
edit: thanks again - your zip works indeed. So after the initial hurdles, now I've got working root and a reasonable way of restoring in case I screw something up along the way.
Before making a new topic with the tutorial I have a few more questions.
First of all, why exactly we weren't supposed to update the rooted devices? I'm not currently interested in OTAs (it's pretty obvious that it needs a functional Huawei recovery, and you need to unroot cause an update can make a mess in a rooted system, making it bootloop for example), but can we flash extracted images with fastboot on rooted devices? Logically, we should be able to... How about sdcard update method?
Can we flash Marshmallow on Kitkat? (fastboot, sdcard, local update methods?) Or do we need to update to Lollipop along the way?
Can I flash stock roms in general (evenbetween different Android versions) by using fastboot with {boot, cust, recovery, system} images only? There's a lot of images that you can extract with Huawei Update Extractor - why there's so many if they're not needed?
hi, i really want to downgrade my S6 to lollipop but i have one of the latest bootloader (DPFX).
Downgrade was perfectly possible when i was on first build of marshmallow, but now, since i upgraded to DPFX bootloader, i have only fails with odin, and bootloops with custom roms...
is there any solution? if only i could flash an older bootloader, then i will be saved.
but if i flash an old bootloader with odin, i have a fail, so i don't know what to do
Some people suggested to me to use an old TWRP backup and i found it on my pc (with all partitions files: bootloader,system,radio and data, but i didn't use data) but using it, it's the same of flashing a custom rom: bootloop, and i suspect that the old bootloader never was flashed.

If you are on a newer mm bootloader then downgrading to lollipop is not possible

I knew this, but i want to know if there is a way, a not official way, like reinstalling bootloader in a forced way that doesn't care about security problems... this thing has no sense.... why totally prevent to downgrade? However, i thing it's NORMALLY impossible, but not
TOTALLY impossible

As far as I know if you're on a newer bootloader official or not there is no current method to downgrade. Maybe a phone shop has specialist equipment to do this but that's me taking a shot in the air
I was able to downgrade but not because i wanted, i flashed a corrupt firmware with ODIN and i have to do an emergency recovery with Smart Switch, my carrier doesn't have Marshmallow on the S6 so my phone restored in Lollipop
I accidentally wiped my Honor 8 with TWRP. Is it possible to get my Honor 8 back to the default OS?

Is the bootloader unlocked? Do you know which model you had? Do you know which version of EMUI you had? Also for future reference do not make new threads without looking in guides because I think the answer is right here. https://forum.xda-developers.com/honor-8/how-to/to-emui5-custom-roms-tested-openkirin-t3638445 . Next time you post try to be more helpful because everyone here will try to help you if you help them help you. Some people may not respond if you do not leave information, or communicate that you need help to provide the information.
If you know you had EMUI 5, this should work (assuming you use the correct firmware files and have unlocked bootloader still). What did you wipe in TWRP?

yes, the bootloader is unlocked, I had the FRD-L09 model, I had the EMUI 5.0. I wiped everything accidentally with advanced wipe.

Next time be more careful. Here are some steps for you
1. Flash TWRP 3.1.1-1 (fastboot flash recovery twrp.img)
2. Download Firmware (If you are in Europe The L09 firmware up top should be what you use. If you are in Asia use the L09 firmware at the bottom.)
3. Move the firmware to your External SD if present and name the folder "Stock Firmware" using TWRP MTP
4. Factory Reset in TWRP (NOT ADVANCED WIPE)
5. Flash your region file before update.zip
6. Reboot to recovery in twrp, this will run EMUI stock recovery
7. Tap factory reset, wait.
You may need to Unlock the bootloader again, but your phone should be okay.

Based on the method given above, were you able to restore the device? It would be new learning for me as i would go for dload but he suggested which was something new for me and i would definitely follow this instructions if i mess up or dload doesn't work.
I have just purchased an S7 which includes the Oreo operating system (binary 5). Will I be able to restore my TRWP backup of Superman Rom (Nougat binary 2) on it? If so, should I just restore boot, system and data?
Thanking you in advance.
EDIT: Thank you for your replies. Restored Superman Nougat ROM on the new device (binary 5). Seems to run perfectly, but yes, bootloader and modem haven't been (and probably can't be) downgraded. Cheers
Yes and no, TWRP will let you roll back the ROM, but the bootloader will stay as is. A mismatch between bootloader and OS version can cause issues, but not always. YMMV.

ymmv? your methods may vary?
nvm, your mileage may vary
HELLO guys I have a problem with my honor 6x ... some time ago I unlocked the bootloader and installed android pie ... but now I would like to go back to the original stock rom because this gives me several problems.
I managed to flash the twrp again but any rom I try to flash does not work ... there are probably errors in the partitions; how do i fix this problem? what method should i use to flash the old rom: twrp or others?
After various vicissitudes ... I don't know how but I managed to install the twrp and through a data format I ended up in the NRD90M test-keys. I must have made a data format to decrypt the twrp on the internal memory.
The bootloader and frp is are still unlocked.
Now what I would like to know is:
1) is it possible to exit the Key test?
2) if yes, how? Which method (dload ... flash from twrp .. hurupdater ... restore to factory data ... Or else?
3) is it worth risking or could I run into a total crash?
Thanks in advance for your answers ...
