Can't downgrade from nougat to marshmallow! - One (M9) Q&A, Help & Troubleshooting

Hello everybody,
I got an issue. I recently updated my M9 to nougat and today I tried to downgrade (With OPJAIMG method from bootloader) but with no success. I also tried to push from adb and the ruu.exe method but none worked. You guys know any sollutions?? Obviously I changed MID and CID to international before doin' all this.
I noticed that I can't even install CM anymore (gives me fail 7 even if in the build.prop i see that himaulatt is supported.)
Hope someone can figure this out.
Thanks....

The reason for your problems is the same because of which people on any 3.x firmware can't flash the 4.x RUU. The encryption keys changed between the two firmware version. You need to flash one of the full wipe or no wipe firmware packs since they're not encrypted and contain the encryption key for their specific firmware. This way you restore the ability to flash a 3.x RUU.

hi,
Same things happened to me.
I flashed android 7.0 firmware(developer firmware and rom) and 7.0 RUU.exe. and I wanted to go back to android 5.0.2. I flashed 1.xx full wipe firmware and 5.0.2 custom rom. but it caused a bootlop until flashed a 6.0 firmware.

I think that you have to flash boot.img from the zip with fastboot.

Everything that isn't already explained somewhere else is explained in my last post. The firmware packs are located in this thread. If you don't know how to flash a RUU you might want to (re-)read the ReadMe thread.

You need to search for them in the forum that belongs to your device. This is the HTC One M9 forum. Chances are very high that no one here owns an A9 and therefore probably no one has the files you need.

Yes with s-off you can change your device to any version you want
You only need the correct CID and MID and a twrp backup or a RUU

I don't think simply restoring a backup is a good idea if you want to downgrade since it doesn't contain the corresponding firmware. It's never good to use a rom that is not optimsed for the installed firmware. Flashing one of Sneakyghost's firmware packs and restoring a corresponding backup should be fine, though.
Nevertheless the most recommended way would be flashing a RUU just like clsA already said.
I read in one of the threads earlier that the firmware generally is OK being the latest, even if you go back to lollipop. Maybe not always but that seems to be the case. Can't remember if sneaky ghost said it in the venom thread or where I saw it though. Problems occur running new software on old firmware. I guess.

Yes newer firmware is OK to run on older version of Android.
It's recommended not to run newer versions of Android on older firmware as it usually leads to issue's.

ruu question

Hi,
Have just got a 2nd hand m9 that I'd like to update to Nougat. It is rooted but not s-off and on lollipop custom rom. Am I right in thinking that I need to install the latest ruu for lollipop, then the same for marshmallow and then lastly for nougat before I can install a nougat ROM?
Thanks
Yes. Updates are incremental. You need to have a stock phone before you can flash ruu's. You need s-off otherwise, which is well worth the money!.

RUUs are not incremental. However, HTC changed the encryption key between firmware 3.x and 4.x. You therefore need to flash a 3.x ruu and to install the non-encrypted OTA afterwards. Be aware that you can't change your sku without S-OFF. That means if you don't own the developer edition (sku 617) you won't be able to update to android 7 since that version is the only one that received the update, yet.

That's not correct. A RUU doesn't care whether your phone is stock or that. It reflashes every partition of your phone as long as your download mode is working.

Hi Flippy,
Thank for the links. As I mistakenly tried to flash a custom nougat rom on my lollipop device, I'm trying to get it back up and running. I still have access to TWRP and was looking at the back ups that you provided. However, I'm uncertain which to flash as I don't know which is the SKU of my mob. How can this be found out?
The readme thread should contain steps (in the RUU section and the twrp section II) for finding out the current firmware version of your phone. Did I forget to add them to the flashing instructions?

No,,that's there but I already know what f/w I'm on - 1.32.401.15. Tried flashing a custom ROM of that version but it's sticking at the HTC logo. I would have thought reflashing a ROM of the same version would have worked but did I bork something when flashing a N rom?
I'm uncertain how to find the SKU but guessing it's 61 (EE UK). Is that going to be my only way forward - ruu or twrp backup?
Thanks for the help!

Re-read what I wrote before and pay attention to the part I highlighted in my quotes.
Btw, since many users make the same mistake I need to ask the following: You checked your firmware in download mode and not in settings>about, correct? The latter only shows you the base of the (custom) rom you're currently using and not your actual firmware.
You're firmware is quite old. I'd suggest you to flash the 3.35.401.12 RUU and to start from scratch. In general, you can't use roms that are based on a different firmware version than your current one. (Sidenote: I'm only talking about the major version number here - in this case the 3.)
There is no Nougat for SKU 401 at the moment but it should get released in the near future.

BTW, I had the issue you described here:-
Copy the file to the root directory of a SD card which is formatted to fat32. (If you're on firmware version 3.x you can use an exfat formatted SD card, too. It would be nice if a firmware 4.x user could confirm whether the exception apllies to the new version, as well.) Sometimes this is only possible if the SD card is directly connected to your PC and not put into your phone. I don't know why some M9s refuse the copy process.
If you delete the file extension , the phone will allopw the copy and then you can rename after.

Firmware flashing: safe to skip versions?

Hi,
I have an HTC M9 with firmware version 1.32.15 , unlocked bootloader, S-OFF.
Can I go straight to 3.xx or 4.xx ? (Or only to 3.xx because 3->4 is only possible via OTA?)
Or is this risky? I tried to read all the ReadMes, but still not sure about this
And I want to flash LineageOS 14 after upgrading the firmware - do I have to do it at the same time?
The answer depends on the method with which you want to update your firmware. RUUs contain the full firmware that belongs to their corresponding version so that you can skip older ones. OTAs and the official firmware packs that get extracted from them on the other hand are incremental so that it's not safe to skip one of them. And with S-OFF (like in your case) you can directly use one of the custom made full firmware packs (which unlike a RUU don't contain a rom/system) for firmware 4.x since they're not encrypted.
The new encryption keys prevent you from flashing a 4.x RUU on a 3.x (or lower) firmware and vice versa. Flashing a non-encrypted file (OTAs or custom made firmware packs) isn't a problem, though.
Unless you use a custom firmware pack (the pack is custom made not the firmware - that one is official) you can flash Lineage whenever you want. However, if you use a custom firmware pack then you need to directly flash a rom via TWRP or the phone won't boot since (as mentioned above) those packs don't contain a system/rom.
Nevertheless, you should never flash GSM files on a CDMA device or vice versa. The partition layouts differ between those two technologies and you'll damage your phone (if you're unlucky unrecoverably) by doing so.
Hi Flippy,
thanks for your answer.
I forgot to specify, my phone is GSM (SKU 771).
If I understand right from Sneakyghosts' firmware flashing guide, RUUs are not an option because they only get released for US models.
And the OTA approach seems very painful as I'm coming from 1.xx and want to go all the way to 4.xx .
So I guess I would go with one of the custom full firmware packs linked in Sneakyghost's post.
Some more questions so I can understand the risks better:

Does that mean the phone would be bricked? Or still be able to boot into the bootloader, recovery and/or download mode?
Could I also go with a NoWipe ZIP instead of a FullWipe ZIP and then flash Lineage?
Did you take a look at the ReadMe thread? If I'm not mistaken then you'll find some 771 RUUs there. I don't think that Sneakyghost provides 771 packs so that you would need to change your CID and flash a pack for a different SKU if you choose this method.
Yes, that would mean that the device is soft bricked. But a soft brick is recoverable since bootloader, download mode, etc are still accessible. You just aren't able to boot the system since there is none. Only hard bricks are bricks that you need to worry about.
Of course you can use a NoWipe pack but there's no benefit in doing so. You'll loose all data anyway since you need make a full wipe in twrp before you flash lineage since the stock rom you're currently using is sense-based and lineage isn't. The exact difference between the two types of firmware packs (full wipe vs. no wipe) is explained somewhere in Sneakyghost's thread.
Sent from my HTC One M9 using XDA Labs
Thank you for clarifying. Yes there is one 771 RUU in the ReadMe Thread, but it's a 3.xx .
So changing the CID to get a newer firmware version seems worth it
Of course you can change your SKU if you want to.
However, you don't need to change it for getting android 7. Since OTAs are independent from RUUs the fact that there is no 4.x RUU for 771 doesn't mean that there is no OTA, yet. And even if there was a 4.x RUU you wouldn't be able to flash it due to the new encryption keys. You would still need to flash the 3.x RUU and then to install the 4.x OTA.
Sent from my HTC One M9 using XDA Labs
right, got confused with RUU vs. custom firmware packs (where it would be possible to go straight to 4).
I will report what I end up doing and maybe ask for more advice... thank you!
I flashed a NoWipe package (4.14.401.7 from Sneakyghost download section), then Lineage 14.1 and OpenGapps 7.1
Everything looking fine until now. Thank you again for your advice!

Hi Lucy,
I used the M9_4.28.401.3_NoWipe_TWRP3100.zip file with GREAT SUCCESS!
I had to change the android-info text first as I was using SKU 502.
I notice that after the install it still showed the old version number in download mode but I continued on to install ViperOneM9 6.2.0
I'm now a proud user of ViperOneM9 6.2.0 !!! Ya-a-a

You don't need to change sku, your phone is AT&T which is a GSM one, so you can flash the international firmware.
If the download mode still shows the old firmware then the flash wasn't successful.
And the SKU gets changed automatically if you flash the international firmware on an AT&T phone since they don't use the same SKU.

Thanks, Flippy. After reading the readme thread, I have a few more questions.
1. Do I need to change my CID in order to install 4.x firmware from 3.x? I have super CID now and Soff.
2. i want to install custom rom, so should I install ATT stock rom or unlocked/developer stock rom? Does it matter or as long as i'm on 4.x firmware, i'm ok.
3. It seems like HTC changed its encryption keys between firmware 3.x and 4.x. Therefore, you cant flash 4.x RUUs if your phone is currently using a 3.x (or any lower) firmware. You either need to flash a NoWipe/Full-Wipe Firmware Pack beforehand (only possible with S-OFF). Can I install nowipe 4.30.617.12 from here? https://docs.google.com/spreadsheets/d/1ZaiJ3F_f76sVa4daU5H62OYi5Bj23LEBBv4xDTQ8y-M/pubhtml
4. Once I install the nowipe package in #3 above, do I need to install the stock rom downloaded from HTC then install any custom rom I want?
I'm going to re-use your numbering system for answering.
1. The CID has nothing to do with the incapability of flashing a 4.x firmware on a 3.x device. And as mentioned in the thread you either need to get back to stock and install the official OTA (not possible with the SCID - that's one of the reasons why I recommend in the ReadMe thread not to use it) or to use one of Sneakyghost's firmware packs for updating the firmware (only possible with S-OFF).
2. Some custom roms (only sense-based ones) support features of the US-carrier-branded firmwares. Aside from that difference it doesn't matter which 4.x firmware you use in the end.
3. That's Sneakyghost's spreadsheet that you can access from the thread that I linked in the sentence that you quoted.
4. Why would you want to waste time by flashing the stock rom if you want to replace it with a custom rom, anyway? Flashing a RUU isn't necessary. Sneakyghost's firmware packs are (more or less) the same as a RUU.zip but (intentionally) lack the system partition.

Green line in video?

I've been having this issue for a couple of months now, tried changing roms with no luck, I am currently using the ViperROM latest version, when I input video either on instagram or facebook or snapchat, I get this weird green lines at the beginning of any of them. Weird part is that at the beginning I though it was the phone but then I noticed that it doesn't do it when I use my camera application.
https://pasteboard.co/GImTnWE.jpg
has anybody seen this before? Any fix? thank you
I currently have that issue on any rom I flash as well.
If you are on a old marshmallow firmware then update to the newer nougat firmware and try again. If i recall correctly the issue comes from that combination.
I have that as well. Running ViperOS's Nougat on a Marshmallow OS. Sucks that I can't update because my phone is from Hong Kong and there's no RUU available.

You can't downgrade with sunshine, you can s-off the device with sunshine and with that you open up the ability to downgrade the device to a lower firmware and/or software version. Please get and learn as much info you can before you start!

Flash the firmware that fits your OS line in the download mode. Look for a 2.41 firmware and flash it like any other firmware. Those guides are plenty described here. Look in the guides section too

So you want to downgrade to nougat, when you do that you also need to downgrade your rom to a nougat OS.
Oreo roms on Oreo firmware
Nougat roms on Nougat firmware
So if you are on Oreo and running viper oreo the rom will stay when you downgrade the firmware only but the rom doesn't work anymore. So i don't quite understand why you want to downgrade when want to use Viper oreo ?

Just can't seem to find the nougat firmware

Why don't you convert since you have S off and leave the telstra firmware and go for a non carrier branded one ?

Here is Nougat for your .841 Telstra Variant.
I'd update to latest TWRP after flashing this.
Says no_wipe so you should be good on not losing your data. :good:

If you are on a old marshmallow firmware then update to the newer nougat firmware and try again. If i recall correctly the issue comes from that combination.

I'm currently running Marshmallow firmware with the latest LeeDroid nougat ROM.
1. I did some research and for some reason my CID doesn't show up in download mode. I ran some command in a terminal emulator and my CID turned out to be HTC__060.
2. I found this thread but the RUUs seem to just be numbers. How do I know which RUU number is the latest nougat firmware?
3. If I flash the firmware.zip through fastboot without S-OFF (phone still S-ON), will it factory reset and wipe all my data?
Thanks a bunch in advance

Can you stop posting in multiple threads at the same time with the same question ! It's annoying and hard to follow.
