I'm wondering if anyone has attempted to install a Marshmallow custom ROM or stock RUU over the Nougat firmware with any success.
I'm doubtful, but perhaps it's possible with S-On. Thanks!
the nougat firmware is not downcompatible with marshmallow roms.
only way would be to s-off, downgrade firmware then, flash the marshmallow rom.
be aware to pick a full firmware though and no incremental one...we've seen a handful people doing this and that ends in a hardbrick.

When I then eventually update ViperROM from Marshmallow to Nougat, will I have to perform a full wipe - or can the update be directly applied?
Trying to plan ahead, thanks a bunch j4n.

well, that sounds like that you are still on marshmallow firmware + rom.
That would mean, you could flash the nougat rom and revert back to the marshmallow one anytime. Just ensure you flash latets TWRP before and backup your data, including sdcard..in case something goes wrong with encryption.
the nougat rom can be dirty flashed.
you know what the difference between firmware and rom is, right?

Thanks, apologies for the confusion. I'm on Nougat, but am planning to downgrade for xposed - then eventually update back up to Nougat once there's a stable release. I asked about dirty flashing since I'm less likely to full wipe for 7.0 after many months of customizing

Has anyone downgraded the Firmware and succeeded? I hard bricked mine twice, first was trying to downgrade it with a full stock firmware from OTA and 2nd time it died when i accidentally picked and flashed a wrong Marshmallow aboot trying to get rid of Hidden Red text which made me believe flashing a Marshmallow aboot while on Nougat hardbricks the Phone. It died at the stage where it should restart so we can run fastboot flash zip Firmware_xx.zip command the 2nd time. It goes black, doesn't turn on, a PC doesn't recognize it, doesn't show if charging. Was lucky HTC took care of the problem.

thats what I said. The firmware in an ota is NOT a full firmware, its a incremental one.
You need a full firmware package like its provided in @Sneakyghost 's threads, with those lots of downgraded already.

Great!! Now i get it, well explained. Thanks :highfive:
As I mentioned I encountered a bootloop after unlocking the bootloader(thanks for telling me that sony).
I read this thread about bootloops.
After that I installed This cwm version.
Now the above thread mentioned to install 4.3 again to recover from the bootloop. But I want to install the nougat rom, so is it necessary to install the 4.3 rom or can I directly skip to the nougat rom ?

If you are currently on 4.3, then you can directly flash nougat. Otherwise you need to flash 4.3 first.

Yes, I have 4.3. So I just download nougat ROM and install it with CWM ? No need for 4.3 again?
Also how to transfer data to sd card. I can't access it with pc.
Regarding sd card issue, well you have to solve it bh yourself

Okay , thanks man.
Long story short, I got pissed at Moto and decided to unlock my bootloader, flash TWRP, and flash a custom ROM (Alberto97's AOSP 8.1). While the ROM is working fine, eventually, I kind of missed the stock ROM, and decided I want to go back (Oreo). Keep in mind, though, I don't want to relock my bootloader as I will flash TWRP and root my device after going back to stock. How do I do this? I do have the Oreo OTA zip with me (Build no. OPN27.76-12-22), if that matters.
When you never were on stock oreo, you can easily flash stock firmware with February security patch (it's 7.1) and then update with the Oreo update zip you find in the forums. Then you can flash TWRP again.

Bro, you and I are on same page. I also rooted my device when I was on stock Oreo and forgot to make a backup of stock Oreo (cuz I'm stupid). I talked a lot to other members and only option that is available for now to get back to stock with boot unlocked and OTA support is wait for Fastboot flash files for stock Oreo. Stock flash files will return your device to original state. I hope Oreo frimware would be available soon (about couple of months). I also want to get back to stock and guess what? I am also using AOSP by Alberto and it's working just like stock, no problem and bugs (there is some data connection bug but I use wifi all the time so it doesn't bother me) so far. Only problem with this ROM is safety net but I don't even use apps that requires safety net certification so I'm good with that too. Basically, it is a perfect ROM for me.
And don't try to back flash if you want to get back to original state, it is true you can still flash 7.1.1 but no guarantee, I just heard from someone but I never tried because I don't want to take risks and even if you got it running 7.1.1, a single OTA will brick your phone for sure. So wait for Oreo frimware, that's the only way and by the time enjoy AOSP.

You'll get back to stock for sure but bootloader will still be unlocked, the only way to lock bootloader is through fastboot flashing of stock ROM. Moreover, TWRP backup contains personal information so not many want to share it but if someone kind enough to make a backup after doing factory reset so it will not contain any personal information then it will work.

Why would one still want to relock the bootloader? It's to my understanding that unlocking it voids your warranty, and I've also read somewhere that even after relocking it, the warning persists.
By the way, have you checked my PM?
Hi guys, in my case I updated from Android Nougat 7.1.1 to AOSP 8.1. now I want to go back to stock rom 7.11 and after that update to Oreo by OTA. Should I only apply Stock Rom 7.11 by RSD Lite??
Thanks in advance

I would recommend you to downgrade to Nougat first - flash everything except gpt and bootloader to avoid hardbrick. Also don't run erase modem commands, they will erase your IMEI in this case. Then, make sure that fingerprint is working with Nougat StockROM. If it does, try to install CustomROM.

Glad to help you.
Just one more thing to mention: don't even try to install OTA updates (in case you stay on StockROM). Here's why. Your bootloader's version is B8.31 now, but phone is "still" running Android Nougat (I guess). Oreo OTA updates the bootloader from B8.25 to B8.31, but since yours bootloader is already updated to B8.31, OTA would try to make a changes, which were already made and break the whole "structure" of bootloader. This would end up most probably in hard brick.
If you'd like to revert back to official Oreo someday, install it using fastboot method. (https://forum.xda-developers.com/g5/how-to/official-oreo-8-1-0-opp28-85-16-t3849244). Even you will most probably loose all of the data, it seems to be the only one safe way to update back to Oreo after downgrading to Nougat.

You must be running NPPS25.137-93-2-5 to be able to update through OTA. However, you can still update to Oreo using fastboot method (link here: https://forum.xda-developers.com/g5/how-to/official-oreo-8-1-0-opp28-85-16-t3849244), but most probably, you will loose all of the data stored in the phone.

It's safe as long as you don't try to flash gpt and bootloader. Downgrading one (or both) of these partition results in hardbrick.

If you update to official Oreo but then decide, you want to install CustomROM, you have to downgrade to Nougat first. Otherwise, your fingerprint won't simply work with any CustomROM. I have already mentioned it in this thread https://forum.xda-developers.com/g5/help/finger-print-sensor-issue-oreo-roms-t3853491.
Btw, bootloader version is not related to fingerprint working or not with CustomROM. There's another partition that makes difference in it.

In my opininon yes, but your opininon might be different. Downgrading from official Oreo to official Nougat isn't difficult at all. You just have to remember, you can't flash gpt and bootloader. It's also recommended to avoid erase modem commands to prevent loss of IMEI.

None of them. Treble project needs Treble TWRP and Treble LineageOS installed firstly for correct functionality of other Treble CustomROMs. More info in this thread https://forum.xda-developers.com/g5/development/treble-project-treble-cedric-t3820451.

I was on 137-93-14 too. I flashed the fastboot firmware 137-93-2-5 to go back full stock and official. No need to re lock bootloader..then I downloaded the latest OTA update 28.85-16 and installed it via ADB sideload.
My phone is xt1670 on channel retca..though I can't say for sure what difference it makes if your on amzin. Wish I could help more.

Yeah your right that was definitely the long way hehe. It's cause I wasn't sure that th oreo fastboot method would have worked for me. I had tried the TWRP version and it kept boot looping so I thought the other way would be safer
