Has anyone successfully downgraded back to Nougat from Oreo? - Honor 8 Questions & Answers

My experience with Oreo has been... weird. My FRD-L04 was upgraded prematurely with the RedLotus method.
I'd like to go back to Nougat and just stick to official updates from there. The bootloader is unlocked. Is there a working downgrade path?

I ended up flashing the latest available Oreo ROM (B520 v161200) over what was already on the phone using the Chinese TWRP, and it seems to be far more stable so far. Since your bootloader is locked, I'm not sure what you can do...

A9 Back to stock -> question about returning to Android Pay and eventually Nougat

I've a device that is S-ON , TWRP 3.0.2-0 recovery installed , unlocked USA. Was running CM13 and later a lineage build...i just wiped/ reflashed the stock boot and system image so i've got things more or less back to original. All's good. However my bootloader remains unlocked. Do i need to relock it to get Android Pay working again? I was able to add a card, but have not tested it in the real world yet. My understanding is locking the bootloader will erase my data. Given I'd like to try that Nougat flavor and I don't think that will come OTA with an unlocked bootloader, maybe now's the time sense I think i'll have to flash that manually
Sorry, still new to joy of working with these devices. Fun tho

No, if Android pay has a problem, it will reject you DURING the process of adding a card, if you add a card sucussfully, your good to go.
If you want to try nougat, please note that that change is irreversible. The firmware is non-downgradeable. I don't think locking the bootloader will erase data, but if it does it PROBABLY will warn you.

Thanks for all that...just to be clear, the only way to get Nougat is to flash it ? or is it also OTA?

It is an OTA, you can have s-on, but you can't have an unlocked bootloader, root, or system modifications if any kind.

Sorry I have a question, I have an A9 (European model) S-ON with CM 14.1 and I would like to get S-OFF in order to back to stock. The problem is that I have read that Sunshine only works with stock ROM and, out of the box, my phone came with vodafone uk ROM and I can't find, on the internet, the exact same ROM as mine ( I have found an older version but because I have S-ON I can't downgrade ). There is another way to make Sunshine works? Thanks in advance

Good, I think you can download the ota and sideload it, should be in one of the general threads. Think it's called any news on 7.0
So, after all this, i had Android Pay (AP) working great w/ 1.57.617.60 flashed back to my phone. I never re-locked my bootloader. This a.m. i flashed nougat, both boot and system (RUU_HIA_AERO_UL_N70_SENSE80GP_ATT_MR_NA_Gen_Unlock_2.18.617.1) - All's great. However while shopping i was rejected by AP with the message in the attached screen shot. Is this because i never re-locked the bootloader? What are the consequences by doing so? Can I eventually re-unlock for future flashing?
NOTE - my device is not rooted, despite the accusations from the modal!

My goal was keep su and also get nougat. A9 has the bug about OEM unlocking just like all other 7.0 devices. It will most likely get fixed at 7.1.1, the nexuses and all other devices running 7.0 seem to have this "bug"

ahh, so that means, as i understand it, if all goes to plan, we should one day expect a 7.1.1 update that will allow me to finally get back to AP?

As long as you don't care about root. You can always downgrade to mm, lock, and OTA back to nougat

No, you can only UNLOCK in nougat. If you want to relock the bootloader, you will have to downgrade to marshmallow and loose your root, or wait for Android 7.1.1
downgrade means i have to wipe data, right? The upgrade that was not the case. I am only assuming

Nougat on FRD-C900?

Background: I got my Honor 8 today, model # FRD-L04 (important later), updated to EMUI 5.1 and Nougat via Updater on phone, and decided I wasn't satisfied with EMUI. So I rooted and that went smoothly, but when I tried to flash a custom ROM, I bricked pretty hard. Long story short, tried flashing multiple ROMs until I found one that worked. The ROM I'm on right now has EMUI 5.1 and build number FRD-C900B131, which is completely different from my original build (FRD-L04). Looked it up and turns out it's a variant of the H8. Unfortunately, I tried to update via Updater and there were no updates available, so I'm stuck with EMUI 4.1 and MM for now (not complaining, since at least it works again). I also tried flashing the rollback ROM for the L04, but I got an incompatibility error when I tried dload method. So now, question is how do I get back to my original stock FRD-L04 ROM, or how do I update to Nougat on this model version (C900B131)?
Thanks for the quick reply. Could you guide me through how I would approach this? I'm not sure which TWRP to use for my (incorrect) build. Do you think using the TWRP for my correct build (L04) should be okay? I'm on EMUI 4.1 also, I think the EMUI version matters too when choosing which TWRP to flash.

Awesome, thank you. I've installed it and it seems to be working fine with no issues. So I found the rollback package for my model (L04), so I should just install this through TWRP? And then install the Honor 8 upgrade firmware? Does that sound right?

Try just flash full firmware, no install rollback. Put zip to sdcard install over twrp and hope for the best, here can happen some unspecific problems. Firmware is right

Reisntalling B385 stock rom to my FRD-L04

Hi guys,
I am currently trying to figure out how to reinstall a clean version of the B385 for my FRD-L04. I have downloaded these two files from the Nougat Update for FRD-L04 Honor 8 (USA):
Full ROM – http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1585/g104/v83098/f1/full/update.zip
Data File – http://update.hicloud.com:8180/TDS/...FRD-L04_hw_usa/update_full_FRD-L04_hw_usa.zip
I have tried to flash them both from TWRP, but I always get the error: Updater process ended error 7
Can anyone please guide me through the process and let me know what I'm doing wrong?
I have look for a guide or post where this is detailed, but without luck. Can anyone link me to a guide on how to reinstall the stock firmware in my Honor 8 FRD-L04?
Thanks! :good:
The best way (if you don't want to unlock bootloader) is to flash a downgrade package first, then dload the Marshmallow update and finally your preferred Nougat update though Firmware Finder.

Thanks for the response. In my case, my phone is rooted, so I don't mind unlocking the bootloader. Would you please elaborate on how to do it that way?

Unlock your bootloader and follow this guide:https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306/
Choose the B385 firmware or any newer firmware available for your region.
So I decided to finally reinstall the stock firmware in my Honor 8 FRD-L04 in B389, and this is where the nightmare began.
- I made a full backup with TWRP just in case and I decided I wanted to start from the earliest firmware possible available.
- I started unrooting my phone using the UnSU zip by Osmosis.
- Then I flash via bootloader the recovery and boot image of the firmware B360.
- I flashed the rollback package from the Huawei official site with the B122 firmware also available at the same place. I saved the rollback package in my root directory in the dload folder, and loaded it with the 3-button method. After this I wasn't able to boot my phone normally, I was stuck in a boot loop. I still continue with the next firmware, the B122, and it was successfully loaded (this also relocked my bootloader).
- It is important to say I clear many times the cache and wipe/erase data through stock recovery options, and also tried to erecover but I wans't able to connect to the WiFi. I guess something was missing (at this point I was already going crazy).
- I was still stucked at a boot loop after loading the B122, so I decided to unlock my bootloader and flash the twrp 3.1.1-1-frd.img
- From there I tried to wipe data and cache and system and everything, but I wasn't able because an error saying unable to mount always appeared.
- After rebooting, since I already had unlocked the bootloader, the initial message prompting: "press power to continue, press for 3 seconds for erecovery, etc..." appeared.
- I enter the erecovery options with the hope it will do something... and it did!!! I could connect this time through WiFi and the system asked to update the firmware and many other things it said at that moment. This was the first time I felt relieved through the night.
- The phone updated perfectly, it started at the firmware B122 and I kept updating it until I reached the B389.
- I unlocked the bootloader again and rooted the phone. And everything is running smooth as silk!
I know this is a very long story, but I just want to get it out there in case anyone is facing the same problem I just passed. Hope this helps someone and brings peace to them! =) Good luck!
I believe B385 is not functional with TWRP. Flash B360 and reboot to recovery. This should go to stock recovery, where you will have to do a factory reset. I got EMUI working, but it refuses to update to any newer version (it does show B380 but doesn't update). Also there should be updates after making that update. The updates did work for other people, so you may be able to have it working.

Yes, boot into oreo er recovery, and select Download Latest Firmware And Recovery, It brings you back to Nougat, I tried it before. You don't need stock recovery to do this.

What command you use. You have Android 7 or 8 right now
Android 7.0 I have been using that app. That boots it into recovery then tries to flash it. I tried to get the adb cmd to work but it doesn't find the file. I know this all sounds like gibberish but that's why I'm lost.
