I had this question as well. i have been running a Kit Kat rom for the past year and am also going to be trying Marshmallow in the next couple days. I wondered whether i would need to 'downgrade' my radio and bootloader if i went back to Kit Kat or to Lollipop.
Along these same lines, I was wondering whether if I didn't like Marshmallow and rolled back to a different android version by flashing a TWRP backup image, would my phone still have the Marshmallow radio and bootloader installed after?
What effects might an out of date or future version bootloader have on the system?

So i found an answer to this in a thread about the unofficial Chroma 6.0 ROM port to for the N5 on the Chroma google community. Here is the post, the relevant question and answer is in the comments. So keep in mind this isn't official info from google but it's more useful than anything i've found otherwise. https://plus.google.com/+KaioDuarteds/posts/EmTVqmPr7ew.
TLR: Tim Seidler says "Yes, you can go back to Lollipop even with the new Marshmallow bootloader and radio."
I did a bit more research on bootloaders too....my understanding is that the bootloader is a small peice of software that starts the phone and shows it where to find the kernel and OS so that can boot up properly. This makes me think that a much older bootloader might cause issues if it were 'pointing' to the wrong part of the phone. If the location of things has changed around in a newer version, the phone might not be able to get the main system running and therefore wouldn't be able to boot. I guess it would depend on how different the bootloaders were between say version 4.x and 6.x, etc.
Having the wrong radio seems less risky. The radio is the modem, it is in charge of handling internet and cell signal connections. The wrong radio might not be able to connect to wifi or cell networks, or might connect poorly, but it shouldnt brick the phone. It seems pretty easy to flash different radios...back when i had a galaxy S2 i sometimes had to try different radios when i installed a new ROM (that had the wrong radio pre packaged in it) because some radios wouldn't pick up my cell provider very well. But i used to flash many different radios (for my device version) without issue. all that changed was the number of bars of signal i got.

Confused about updating to a GPE

I'm running stock RUU on Verizon's latest 1.55.605.2. All radios, etc are current. I'm rooted with s-off. Now my question is am I able to flash a rom like a GPE that is based off the 4.4.4 update even though it hasn't been rolled out yet to Verizon. I am very confused because I see some roms based on that update despite the Ota not being available. I've tried flashing a couple of roms that are 4.4.4 based but was unable to. Why can't I run a 4.4.4 rom even though I am s-off? And how are developers basing their roms off of it when it hasn't been released to Verizon. I am just completely lost.
I think you're confusing Sense with Android (GPE). Sense is currently at 4.4.2 and about to be 4.4.3 later this week. (HTC is going to skip 4.4.4 because the updates to 4.4.4 are rolled into Sense's 4.4.3.)
You are able to flash GPE based on 4.4.4 or 4.4.3 because the Android version is unrelated to the baseband version. Don't hold me to that though. With Samsung (what I had before this) baseband enforced a minimum Android API level (OS version) but not a maximum. For example, when I flashed MJA, I had to use 4.3 and later. Could not go back to 4.2 or prior. But never mind that, that's Samsung talk. But I assume it's the same. Samsung uses alphanumeric, HTC uses what looks like IP addresses but aren't. 1.55.605.2 is indeed the latest for the VZW One M8.
I don't know why you were unable to flash 4.4.4 ROMs. Sometimes an older version of your recovery (e.g. TWRP) can make it impossible to flash recent ROMs. Check and make sure your recovery is current.
You can definitely flash either of our GPEs, but be warned they are not ready for prime time just yet. The current issue is that signal will drop irregularly in both of them. But we have some smart people working on figuring that out. GPE is typically only available for GSM phones (e.g. AT&T, T-Mobile, International unlocked) and making it work with CDMA (i.e. Verizon) is a nontrivial task. But they're trying. And for some, the issues are forgivable. For me... I'm patiently watching and waiting.
Lastly, you won't get the OTA because you're S-Off and/or because you're rooted and/or because you have a custom recovery. You'll never officially have Sense based on 4.4.4 because HTC's not doing it. Next week or by the weekend, we'll probably start seeing Sense ROMs based on 4.4.3 since that's what's coming.
You're able to flash GPE simply because you're s-off. Once you have s-off, you can flash anything you desire. No guarantees it's going to work though. If the rom isn't ported for Verizon, it's not going to work. You have to do a little homework before you flash a given rom. Read through the thread. If nothing else, search the rom thread for Verizon. More than likely somebody has asked if it will work on Verizon and if so, you'll find your answer.
As to flashing back to an earlier version, once again, you're s-off. You should be able to flash anything you want. I'm somewhat new to HTC also but from what I've read, I don't think you'd have any problem going back. I know with Moto phones it wasn't possible but that was because the bootloader wasn't unlocked and the newer version came with a new bootloader. Since it was locked and the new bootloader had a different signature than the old, you couldn't go back. You're unlocked on here though and it should take anything you throw at it. Old bootloader should be no problem. Should be able to go back. Somebody can correct me if I'm wrong but from what I've read, that's how I see it.
There are two gpe ROMs in the Verizon Android development thread which have been specifically ported and catered to the Verizon devices. Both sjould suffice. Under NO circumstance would I recommend that you flash a GPE ROM from the unbranded HTC development. Same goes for GPE/SENSE kernels.

Not able to update Verizon HTC ONE M8 to Android 4.4.3

Hello!
I have a Verizon HTC ONE M8 that no matter what it won't download the new update. I've bought 3 of them (identical) 1 month ago from Ebay. One of them was able to receive the update. On the other two i keep receiving the following message: "We were not able to download this update. To retry, go to Settings > Software update. "
My device is S-off (after a lot of effort). I've tried to get rid of all the bloatware and many more by flashing a new ROM. I have tried flashing ViperROM, ARHD, Clean ROM using TWRP Recovery, without any success. All of my attempts got stuck at the booting screen for more than 30 minutes without any success of booting into the OS. Clean ROM even refused to flash properly. Keep in mind that all the ROMs that I've flashed were based on 4.4.2 firmware, the one that my phone came with, not 4.4.3. I've searched on this forum for a flashable 4.4.3 OTA update, but no success either. What's to be done !?!? All my attempts of installing a new OS failed. Please HELP!
P.S: I'm a newbie when it comes to all of this stuff. First time doing S-off/ installing custom ROMs.

You probably won't be able to take the OTA with a custom recovery, it has to be stock. Best bet is to flash the 4.4.3 firmware from the development section since you're s-off, then flash an already rooted stock 4.4.3 rom. It's been a while since I've done this stuff so if I mentioned some incorrect info, my apologies.

I flashed back again the stock ROM and i keep receiving the same message over and over again. No TWRP recovery this time, just the red triangle. I guess my best bet is to try and flash the CleanROM ODEX 4.4.3 as mentinoned here: @branmuffin17
I'll come back with the results.

If you are on the old firmware you need to update firmware separately.
And btw, if you freeze just one system app that can cause a Vzw ota to fail.
Question.....Is the phone active on your account? I also had one in the drawer and got the same error till I switched it to the active device on my account.
It honestly sounds like there is something preventing the ota to even download, if that's the case use dottat's ruu to return to a clean slate, if it still won't download the OTA then I would be willing to bet money that they are defective or not genuine Verizon M8s And if I were to guess it's more of the latter that would be the only valid reason every Rom you've tried fails no matter what.

Based on what you said i went on some websites to check the IMEI/ESN of the device it seems to be OK. After that i went to the Verizon Wireless website to try an activate my phone and when it comes to "Enter your Device ID to check eligibility", I type in the IMEI and the following message apears: "The phone associated with the Device ID you entered is not compatible with the Verizon Wireless network." To me is strange because on the back of the phone it says Verizon 4G LTE. When it comes to the identity of the phone it is a HTC6525LVW. The phone is GSM Unlocked (I use my phone in Europe so i needed it to be GSM unlocked). More strange it is to me that i don't receive the same message when i type in the IMEI of the others Verizon GSM unlocked HTC's ONE M8 that i bought along with this one.
I guess my only chance is to flash the new firmware @here[and after that flash the Deoxed 4.4.3 Stock Clean ROM @here. If it's not going to work i really don't know what's else it's to be done.

The message from the vzw site tells me something is not right.
Google goophone or knock off gs4, the goophone also has an m8 now too... Even with all the branding and everything. And I've seen some gs4s that run what appears to be TouchWiz cloned to a T.
I'd try calling vzw and talk to a rep and it's possible that they could give you more info other than just what the site said.

So I did what I've said:
1. Installed firmware provided here @Tigerstown
2. Installed the Odex Stock Rooted ROM proivede here: @scrosler
I am pleased to announce you that everything is fully functional now
Phone is showing:
Android Version: 4.4.3
Software number: CleanROM 2.0.0 (after flashing it from @here)
Baseband version: 1.09.20.0702
Bulid number: 2.21.605.2 CL362279 release-keys
After managing to flash the 4.4.3 version of Android all went up without any problem. Tried to ARHD but it's still not booting. After that installed ViperROM which went up all, but to me it is not the pure HTC Sense 6 experience i was looking about and all that customization is to much for me, so i flashed CleanROM 2.0.0 and here I am. Everything is as it should be: no bloatware, pure HTC Sense 6, optimized performance... and above all the mobile hotspot is now fully functional, not to mention the EXT SAVER.
As a conclusion, to all that guys that are not able to update to the 4.4.3 version via the OTA updates provided by Verizon do what I did above (steps 1 and 2).
ATTENTION: Your device needs to be S-Off and bootloader unlocked + custom recovery!!!
Another thing worth to be mentioned: it would be great if the admins could flag this thread, cause I've seen so many users on different forums that are not able to update via the OTAs.
In the end i would like to thank to all the devs out there for their work and to the users for their support. Cheers!:highfive:

Help with downgrade?

What i have: a brand new carrier unlocked samsung galaxy s7 sm-g930w8 - came with 7.0
What Id love to do: downgrade to 6.0.1 official touchwiz rom but rooted
What im reading: that the security patch is from february of 2018, which means the bootloader is too new, which means downgrading using odin wont work ( https://www.sammobile.com/forum/threads/36282-Does-Region-Matter )
... so what can i do? i bought this phone with the sole intention of downgrading, as ive seen that it is possible for that phone model (s7) in general
i hate the look of the newer OS. They took the touchwiz out of touchwiz which i loved, although mine is a rare opinion. I want the operation and exact feel of 6.0. the menus are simpler, the notifications area isnt completely stripped of features differing from total stock android. i hate having to pull down twice to see everything. I just really want that older look and feel, but all around, not just a theme.
is there anything i can do to either downgrade or fool the bootloader into letting me carry this out? is this a true limitation, or si that info i found false/old? and if I can downgrade, which build version should I use?
ive been looking here for versions
https://samsung-firmware.org/model/SM-G930W8/ but im not sure which region to go with, or if i can technically use any region
sammobile doesnt list that version anymore at all ( https://www.sammobile.com/firmwares/galaxy-s7/SM-G930W8/ )
https://mobiletech360.co/samsung-galaxy-s7-sm-g930w8-stock-firmware-rom-android-6-0-1-marshmallow/ there are a number of options here but unsure of the different numbers/builds. or if since its carrier unlocked, i could pick any?
I know most will think im silly for wanting to downgrade or caring that much about appearance, but silliness aside... is this even possible??
a while ago, i purchased an s5 mini, and downgraded that with no issues at all.... but its honestly been so long and i cant for the life of me remember the steps i took or if i needed to care about region codes or other numbers. but it did sucessfully work.... it was really built unwell/cheap, but it did work.... its also slower than my captivate glide which is still my current phone, until/if i can get this s7 working the way i desire.
any help and guidance is appreciated. If it is needed, ill be using it with a Koodo mobile sim.
well it is too new if its from DRAG or so onwards (those with U2/S2 in the file name) so no dice, you're stuck with 7.0 unless you want to upgrade to oreo. (and 7.0 firmwares prior to DRAG cant be downgraded to either, not that theres much point doing that)
btw this is the wrong forum to post this in

But this is the forum about s7? I'm wanting to modify an s7?
Which part of the file name are you referring to? Which file?
I would have thought all s7's are made at the same time, and so released with the same overall software, but it all seems so complex now. I've seen s7's running 6.0.1 stock so in my mind it seems they should all be able to...
Not sure what you're referring to with drag either? Does that stand for something?
I'm really hoping this can work somehow, its the last flagship before the edge models which was why I got it, and I love Samsung software up until 7 and 8.
My mom has an s7 as well, not rooted or anything that's too complex for her, but she did the upgrade to 8 and it's still got all the same gross appearance factors that I don't like about version 7. I got excited when her phone wanted to upgrade, maybe they had fixed some of the grossness. But, nope. Wish they had included an option even for stock based or touchwiz based appearance and menus.

go into about phone and tell me the last 6 characters of your build number
(i was referring to the PDA file in a stock firmware zip)
(Also i meant this should be in Q&A section)
Hello,
I can understand you and also understand what you want but Samsung installed a downgrade lock in their bootloader in early 2018,
if you installed this version you can't go back to an older version, I think that was in February.
You can go back from a 6.2018 version to a 4.2018 version for example but not to a 1.2018 version!
If you have a version of for example 12.2017, you can also go back to a version of 2016, so you can also go back to Android 6.01,
if not you only have the last versions of Android 7 or update to Oreo.
I hope I could help.

the last of the build number and the last of the baseband version are the same. But i did take a screenshot of it when i was thinking rooting and changing would be no big thing. figured that would be easier. i purposely havent even hooked it up to wifi yet or anything, said no to anything non essential when i was setting it up... on the chance it was starting up in version 6, and i didnt want it upgrading on its own.
also why would they block downgrading? It seems if anything blocking upgrading would be the way to go, to stop people from updating their devices before official software is ready, not just samsung but any manufacturer. in my head it seems silly to even need to root anymore... someone always figures it out, and cell phone manufacturers must know it. it would be nice if it were included, sort of like developer options, where its hidden, but if you know what to look for its there, and if youre not that advanced youll never find it.
if the bootloader is in fact locked and that is the main prevention, has anyone ever successfully unlocked it before?
ETA: Ive done a bit more looking around and there is alot around about frp and making you sign in to a google account in order to reset.... i have *not* needed and havent signed into a google account on that device at all... does that mean a downgrade is still possible though odin? Or, are these 2 things in fact unrelated...
eta #2: Did a bit more searching around, and it seems to be that in order to root your device, in the process it must unlock the bootloader? If that is still the case, would i be able to then flash the marshmallow stock ROM? Thats what i was looking to do all along, sorry maybe i should have been more clear about my planned method initially. Its a bit more nerve wracking as it seems rooting itself has gotten a little more difficult with that dm verity thing... but I definitely want root no matter which version im running. Ive had root on all my devices and theres no way im going back to a locked down OS (cant remove microsoft stuff for example), i need to be able to declutter beyond what factory allows lol.

TL;DR
your bootloader is currently on version 3, and you cant downgrade to marshmallow
see that "U3BRB2"? that "U3" means your bootloader is on version 3. i assume the marshmallow firmwares use bootloaders pre-version 3 so you cant downgrade to firmwares using bootloaders with version 1 or 2. (this is how it works for F/FD models and im pretty sure samsung made it like that too for the W8 models)
eta 1) unrelated
eta 2) F/FD/W8/S/K/L variants (basically all the exynos models) have unlocked bootloaders. only SD variants have locked bootloaders so it's just your misconception
So, it's literally impossible? Has nobody ever figured out a way to downgrade or mod the bootloader itself? It seems to me the rom makers wouldn't stand for this at all and would figure out a way around it...
I can see an old bootloader can't run new software, but it seems much easier for newer bootloader to run older software, isn't it? You can buy a windows 7 pc and install Windows xp on it much easier than you could buy a windows XP PC and install Windows 7 on it... It's just boggling my mind a little

Off course you can downgrade to Marshmallow. To unlock the bootloader, enable OEM unlocking in devlopper options. After flash TWRP 3.1.0 for Herolte and wipe everything from the recovery. Install any 6.0 roms on XDA for G930F then flash Magisk 17.1 to root and you're done. You can't FRP if OEM unlocking in devlopper is enabled.

You'll trip knox (which breaks features like secure folder, private mode, shealth and Sbrowser private mode) and lose the comfort of OTA updates if you do this tho. Not to mention that you can encounter signal reception problems because your flashed ROM is on marshmallow and your bl/cp is on Oreo or nougat. So I wouldn't advise this method as it may break so many things.

Any way to downgrade from Nougat to MM without losing FP Sensor,Haptic Feedack&Camera

Any way to downgrade from Nougat to MM without losing FP Sensor,Haptic Feedack&Camera
I recently purchased a new S7 not realizing that it was equipped with a Nougat OS. I would like to restore my current phone to the new one, but my current phone runs on MarshMallow. After restoring the backup, my new phone has no haptic feedback, no fingerprint sensor with "an error has occurred with the fingerprint sensor. if this message appears repeatedly, restart your phone" message and the Camera doesn't work.
I'm sure it has something to do with bootloader N using MM. Even restoring Stock Marshmallow firmware (Including BL) on the new phone removes these functions. Does anyone have any ideas on how I can get these to operate?
My current phone has
Bootloader Version: G930W8OYA2APK3 (MM)
Baseband and PDA Version: G930W8OYA2API1 (MM)
When I restore my old phone to the new one, it ends up with
Bootloader Version: G930W8OYA2BQK4 (N)
Baseband and PDA Version: G930W8OYA2API1 (MM)
EDIT: Just tried the Nougat firmware with MM Bootloader. All of the functionality is present.
Bootloader Version: G930W8OYA2API1 (MM)
PDA Version: G930W8OYA2BQK4 (N)
Just restored old backup with MM bootloader (Boot, Data, System only).
No Fingerprint Sensor or Camera.
BTW, ignore the HAPTIC FEEDBACK portion of this post. I believe it is working.
Any help with this matter would be greatly appreciated.
Not possible to downgrade since the bootloader block you from flashing lower version of that. You may try to flash without BL, but your phone will be malfunction
Thank you for your reply. I don't think I'll be able to get the fingerprint wizard to work but having a functional camera would be a necessity. From the System/Priv-App folder I copied the SamsungCamera5 (from MM) and the SamsungCamera6 (from N) onto an SD Card. I guess I can try to play around with them to see if either will work, but I don't think they will since my restored backup should already have SamsungCamera5 and the SamsungCamera6 apk probably isn't compatible with MM. Kinda disappointing that I'll have to continue to use my old phone with a broken screen instead of the brand new one I purchased.

I guess I can try to play around with them to see if either will work, but I don't think they will since my restored backup should already have SamsungCamera5 and the SamsungCamera6 apk probably isn't compatible with MM. Kinda disappointing that I'll have to continue to use my old phone with a broken screen instead of the brand new one I purchased.

do not flash AP from a firmware set made prior to the bootloader youre on, it will more than malfunction, itll probably brick
i went back and read all the tl : dr stuff and saw that you seem to have got it working, oddly enough. The camera issue is likely the kernel
Thanks for the info on the thanks button. I've just about given up trying to get Marshmallow to work properly on this phone. Looks like it'll take weeks to configure my new Nougat phone to be similar to the three years of tweaks I've made to my old MM one. Oh well, first world problems I guess.
As others have pointed out, you can't use Odin to successfully flash a ROM with a bootloader that is earlier (in version) than the bootloader you have installed. The "gatekeeper" is Odin, however, not the bootloader.
Though I haven't tried it, it is my understanding that there is a way around this. Install TWRP, and use it to install a custom ROM which uses the version of bootloader that you want/need. Once the bootloader has been rolled back, you can use Odin to reinstall Nougat (or whatever). I don't know whether this might require a particular build of Odin, but I doubt it

i cant even begin to imagine how/why that would work. the bootloader doesnt really care what ROM you install, its the other way around. The ROM being installed has to be compatible with the bootloader. So, installing a ROM wouldnt really do anything to the bootloader and therefore wouldnt be able to bypass the lock in knox.
The procedure I outlined apparently works where the custom ROM includes a related bootloader. Thus, when it is installed via TWRP, it replaces both the existing ROM and the bootloader. I know that TWRP can be used to install a bootloader, as I have done it (on a SM-930F). And if the gatekeeper is Odin and not the bootloader itself, then this could work.
As I stated, I haven't tried this, nor have I extensively researched it. I've only read about it, and am passing it along as a possible solution.
This post can be closed since the phone was deemed Lost or Stolen by the carrier, therefore they couldn't unlock it for me to use my SIM card. I've since returned the phone. At least I learned a few lessons for my next one. Mainly, back up the phone when you first get it. Thanks again for all of the feedback.

Firmware partitions question???

i've never flashed firmware partitions before on my other 2 moto devices, i understand having read the install of lineage that this step is req'd for this model.
i'll be using the lineage recovery to install the rom flash, this is the method ive done before. My question is once i sideload the firmware partitions, will this automatically asign which partion the rom will be written too or do i have to tell it which one, im understanding that it will be either A or B partition??
I'd like to wipe/erase as much of the stock rom off the phone, remove everything and then flash the operating rom to a clean phone. Am i understanding this correctly or missing anything? Is there anything that i need or should know or do when at this step? any help/advice would be greatly appreciated.
This is a brand new phone out of the box, is there other ways that any of you would approach this phone to totally wipe it, i'm hoping that ill get the android 11 update immediatley over ota, i understand that i will have to go through intial setup, to get to unlocking the bootloader, wish i didnt have to do that, also i dont believe kiev has an official android 12 oem/factory rom but lineage has 19.1, im thinking install 18.1 and then later reflash android 12 when it comes out. Im talking to much.... any advice be great. TIA
First things first, know your device. Is it an XT2113-2 RETUS variant or something else? As long as the bootloader can be unlocked, it seems any kiev (qualcom) variant should work with lineageos - just best to know what you started with in the event you need to ask for assistance or you want to revert back to stock.
My suggestion assuming you are starting from a new phone out of the box with the plan of putting official lineageos (either 18.1 - android 11 or 19.1 - android 12) on it:
Have the phone ota update to the most recent stock firmware. For XT2113-2 RETUS at the time of this post, this is android 11 version RZKS31.Q3-45-16-8-3 released 2022.06.30. Lineageos currently uses the binary blobs from this version. I suspect having the latest stock radios and bootloader on your device will result in fewer issues and may likely make your life easier later.
After updating to the most current stock version, request the bootloader unlock key from the moto www site. You may need to wait 24-72 hours or longer before the phone will allow unlocking. Leave the phone on, connected to your (primary) carrier, and use your carrier data (i.e. not wifi) during this time.
After updating to the most current stock version, put all the sims in the phone for the carriers you plan to use and let the phone provision the carriers (I've read this can only be done on stock firmware - switching carriers without having done this step apparently requires going back to stock). Test that you can swap sims and use the phone as you need to (e.g. wifi calling, try visual voice mail, try 5 G, etc).
Unlock the bootloader. Be sure to leave the oem unlocking toggle to allow after unlocking the bootloader.
Most important: when coming from stock (either now or in the future), follow the instructions on the lineageos www site. In particular, flash the copy-partitions.zip following the sequence described in the lineageos instructions. Don't worry about the A/B partitions for now, the device will take care of itself. You only need to flash the copy-partions.zip when comming from stock (either now or if you reflash stock in the future and then want to go back to lineageos).
Flash official linageos 18.1, android 11 (not 19.1- android 12). 19.1 is the newest version; however it may have issues. 18.1 works great (for me) and it will likely be easier for you to check if everthing is working as you expect. Upgrade (via ota) to lineageos 19.1 in a month or two.
Updating official lineageos via ota, the device will flash to the appropriate A or B partition. You should not need to do anything unless there is an issue.
I'd like to wipe/erase as much of the stock rom off the phone ...

Following the lineageos installation instructions will accomplish that.
Good luck.
notmyrealhandle, thanks for your time and reply, perfect write, i understood everything you said. i never thought of doing ota via data as opposed to wifi, thanks. perfect​
