Don't own this device so a few questions.

Okay, so, one of my friends has a OnePlus 3 and it disappointed in the battery life after the Nougat update, he wants to roll back to Marshmallow.
So,
1. Is rolling back to Marshmallow possible after a Nougat update? Are there any risks for flashing Marshmallow on Nougat's bootloader?
2. Can someone tell me what is the latest stable (don't want betas) Oxygen OS based off Marshmallow.

1. Yes, its fairly easy to roll back. Minimal risks If done corectly
2. I believe the latest mm build is 3.2.8 (not sure though)

I'm not sure If we're allowed to post external links but, you can go to Google and search for "downgrade op3".

This is best marshmallow in my opinion of course

Remember that op3/3t N have f2fs file system which is unsupported on 3.2.8 (MM). You'll either have to use an old version of custom kernel (I think only bluspark supported f2fs at that time) or convert to ext4 in twrp. Other than that there should be no issue with flashing 3.2.8 over N

No Radio on ROM Flash

no matter what i do with my htc 10, i always lose radio on flashing rom, i looked and it say only flash oreo roms if you are on oreo firmware, which is what i am doing. i am formatting data like it says to do to rid the encrypyion. because of this i have to restore from RUU everytime to fix radio, restoring from a twrp backup does not fix the radio. home button stops working aswell but it doesnt work in twrp either. is there any way i can fix these problems?
Thank you for your help

I tried PureFusion and AOSiP
My radio works fine on fully stock (which is what i am running right now) but when i goto flash a rom i lose radio and home button, i just wanted to clarify because i didnt know how good my initial explanation was.

Yeah, ï believe purefusion is based on the nougat firmware so that explains the loss of radio. Check the specs before flashing.......maximus, leedroid or viper should work fine.

You have to read more mate, just checked the OP of the AOSP rom.......
It says it needs N or MM firmware so no O (oreo) firmware.

Hmm... what about purefusion though, i cant see anything on that page about what firmware i have to be on but i read somewhere you have to be on O firmware for any O roms to work and you cant flash N roms if you are on O firmware.

Yeah it says O firmware required. is there a specific way i need to erase the device in TWRP other than formatting data to rid the encryption? just want to be sure. it only says to erase /system and /data if coming from another ROM, im not sure if this includes stock sense also?

Especially going from stock sense to an AOSP style rom it's wise to wipe the whole thing because you don't want to mix two roms, strange behavior may occur.
Follow the instructions in the specific thread, if you want to run the phone unencrypted then you need to format data indeed.

Hey sorry to hijack thread but I'm having a similar issue, any sort of flashing I do results in the airplane mode getting stuck to "turning off" and I can't use my mobile network. I can flash my official T-Mobile RUU zip and things will work fine, but if I flash twrp on official it breaks. I switched over to the unlocked Dev rom and it breaks. I can only get my official zip working. Any help?
My specs are:
Android 7.0
2.51.617.32
S-off locked
1.0.U010241a 6117.76.02_f radio
Switched cid to bs_us01 or whatever the Dev cid is. For the rom. Other than lineageOS which didn't work, I haven't tried any other rom except dev.

Twrp works and flashes normal, it just breaks my airplane mode making the network unusable when I try to do any sort of modding to stock.

Just as all the other comments, read what you are flashing and which roms.
Nougat firmware - nougat roms
Oreo firmware - oreo roms
You have NOUGAT firmware so ONLY nougat roms work.

I am flashing nougat roms, the wwe/dev rom I have running atm(which is giving me airplane issues) is the same as the official T-Mobile ruu I have that works, only difference is that it's the dev edition instead of t-mobile, same firmware and both are Android 7.0. Flashing full RUU and not any of these custom roms on here. I had only flashed lineage to see what it was like But got rid of it and put on my working T-Mobile ruu.
Both T-Mobile and dev edition RUU is taken from the official HTC website, they're the exact same thing.

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.

Ota update opp28-85-13-2

Please someone help me
I'm looking for the official OPP28-85-13-2 OTA, I need the zip to update to that version officially
I'm looking for it because it solves the low sound problems and the October security patch:crying:

Sorry that I answer so late, when I was searching for ways to update to Oreo I found this post:
https://forum.xda-developers.com/g5/how-to/cedric-ota-archive-t3795275
It's a collection of ota files, it also describes the order how to flash them.
The otas and the list for that are here

Edit: I'm currently on OPP28.85-16 but I don't know if you will find the otas for this, but I flashed firmware directly, guess when you don't want to reinstall your phone this is not an option?

Question LE2120 - > Oxygen OS 11.2.5.5.LE15DA to LE15BA

Hi all,
I've the 2120 with the OXOS 11.2.5.5.LE15DA I would flash my device whit the EU version. LE15BA.
I'ts possible flash it using the FULL 11.2.6.6.LE15BA ?
I just tried with the same version number ( 11.2.5.5.LE15BA ). but does not work becase the version number is the same.

Hello,
Yes you can flash full OTA of 11.2.6.6LE15BA without any problem without losing anything through local upgrade.
Or you can do what i did, download a downgrade ota file. In my case i was in 11.2.5.5LE15DA and downloaded downgrade OTA of 11.2.5.5LE15BA and flashed again through local upgrade, but since this was a "downgrade" it wipes all data. I didnt mind the wiping since i couldnt wait for the new update for too long.

How to downgrade the current version?

[OnePlus 9 Pro][ROM][OTA][Oxygen OS] Repo of Oxygen OS Builds
As OnePlus doesn't always provide download links for all of their OxygenOS ROMs & OTA update zips, we've created an index to put the links in one post so that they're easy to find. Note: This is not a support thread for issues you may have with...
forum.xda-developers.com
Go below find the downgrade zips
Find the 11.2.5.5LE15BA and download it. Then flash it through settings>local upgrade. And when you click on downgraded zip it will notify you all data wil be wiped, click continue isntall and phone will reboot into recovery, wipe all data, boots into android setup. I think this is best options since it cleans flash the old version.

[OnePlus 9 Pro][ROM][OTA][Oxygen OS] Repo of Oxygen OS Builds
As OnePlus doesn't always provide download links for all of their OxygenOS ROMs & OTA update zips, we've created an index to put the links in one post so that they're easy to find. Note: This is not a support thread for issues you may have with...

No need to be rooted. You go to the Downgrade zips links and download whichever variant you want of the 11.2.5.5. Then through Settings-System updates- Local upgrade, pick the downgraded zip you downloaded. It will promt you that you are Downgrading and it will wipe data, and after you confirm it and install it, phone reboots into recovery wipes data, reboots to android setup.
