[Question] Can you downgrade marshmallow? - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

Anybody taken the Ota and wanted to go back? I know going back to kitkat is apparently not possible due to security patches, I was wondering if I made the jump to 6.0 if I would be able to go back.
Can you twrp a previous version of android if you restore?
Heard iffy things about the mm update for us so I've avoided it

[Q] Sell my moto G but screen is flickering

When my regular moto G was at 4.4.4 I decided to "upgrade" my phone to 5.0.1 GPE. Then, for some reason, I did not want GPE 5.0.1 anymore, so I downgraded to stock 4.4.4 then installed cyanogenmod 5.0.2.
The result is the famous screen flickering - which can be solved by locking/unlocking the screen once.
Now I want to buy a new phone and sell my moto G. I'm wondering how I could get rid of the screen flickering. People will think that the moto G is somewhat damaged and will not buy. Will the screen flickering be gone if I downgrade to stock 4.4.4 again? Or do I have to wait for kernel fix?
Best regards
Martin
Kernel source is out. I personally haven't used it yet but I'm thinking that should solve it.
Ok
Could I just flash that kernel on my phone then? Where can I find it? Thanks for your help, I'm new to this
If an OTA update to 5.0 is available for your phone, flash back to stock and take the OTA update.

Hmm, the OTA will come. Dunno when.
Lets say I do as you suggest, will I get the OTA even if I don't have exactly the same stock image as when i bought the phone? Cause I can only find this (i'm from Sweden):
XT1032_RETAIL-EU_4.4.4_KXB21.14-L1.4…d7_CFC_1FF.xml.zip
You think that would give me the OTA Lollipop when it comes?
Best regards and thanks a ton for your help
I'm not sure, but if it isn't available through OTA, maybe you can find a stock image later.
I flashed my Telus xt1032 back to stock 4.4.4 and it keeps saying my software is up to date, but I know it isn't. It may take time for the Lollipop update to happen.

NON-ROOT 100% STOCK Lollipop? Does it exist?

I want to sell my phone, a D850, that I've had for just under a year. I've unlocked it so it will work outside of AT&T. The question now is: can I unroot back to stock but with Lollipop instead of KitKat? Alternatively, can I update my G3 with an OTA update.zip file after going back to KitKat? Is there any way to do this manually without having to rely on the actual OTA update coming down (because my phone for some reason just absolutely refuses to update by itself)?
Any help would be appreciated.

Help with my Honor 4c 4.4.2

My phone Honor 4c is currently experiencing unexpected problem.
It started after I downloaded the updates in my phone using wifi and my stock build was B070 then after the 2 updates which was downloaded accidentally my build goes to B180. I tried many things just to revert this and go back to my old build which is B070 but the version failed it keeps saying error/failed..
Can someone help me with my problem, i really want to upgrade my phone's OS from KitKat to Lollipop or even further (Marshmallow)
Why do you want to revert back to B070 from B180. You have to take OTA updates to upgrade to a newer version. Sit tight and you'll automatically receive the Lollipop update B320.
my build no. is b180 and when i check the updates in settings and said that no updates available?
pls help, i want my huawei honor 4c to be lollipop to marshamallow,pls help
sorry for bad english,hahah

What is the process for Android Updates?

Hey guys. I was wondering, what is the process for android firmware updates? By this I mean, when I owned an iPhone (any model) after I updated the firmware there seemed to be remnants of the old firmware version and it would cause issues through the phone, at which point I would have to go on my computer, restore to the newest firmware essentially formatting the phone and re-uploading the new firmware on the phone. After that all was fine. Is this necessary on android in order to get a new, clean version of the firmware on the phone or does the update process do this throughout the installation? I haven't had any issues yet with the newest AT&T Nougat update, but I was just thinking about this and figured I'd ask before anything did happen, if it's like my old iPhones...
BTW, I'm on AT&T Samsung Galaxy S7 with Nougat 7.0

Downgrading my (unrooted) carrier locked At&t Note 8.

My note 8 had OneUI pushed to it about a week ago even though I kept refusing not wanting to while I was sleeping. It says my bootloader is v5. This is actually what it says (N950USQU5DSD3). My problem is that when I search for the firmware I'm wanting to downgrade to (the last oreo update possible for this particular phone) on Sammobile I can't find the one for At&t. I see ones for Verizon, sprint, etc. But nothing for at&t, which one am I supposed to use and where can I get it? This is going to be my very first downgrade/upgrade, really my first time doing anything like it on android. And I CAN do this right? There's nothing I should be aware of that makes what I'm trying to do not able to be done is there? The biggest reason I'm asking is because I have very limited tools to work with, I have a little 12" Acer aspire one (no disk drive) running windows 7 home basic, mobile hotspot from my wife's phone(the last software I tried to download and use came from xda out of a thread I found titled, "Stock Oreo N950USQS5CRF6 Odin*files*for AT&T*NOTE*8" it failed halfway through 2 nights ago during the beginning of storm, and the whole time it would only download around 32kbs so it literally to FOREVER! Only for it to fail halfway through. Was I wasting my time or was this in fact the firmware I'm looking for? If not, as I asked before, where could I find it?? Thanks a bunch for any help.

^^^^^^^Is this all I need? Do I need to follow this tutorial or a different one?? What version of odin, do I need anything else
Sorry for so much all at once, I really hate this update and want Oreo back.

Follow the steps from the above-linked post, and follow them very carefully. I did, and I was able to successfully downgrade from Pie to Oreo on my AT&T NOTE8.
I actually flashed the unlocked firmware, which has zero AT&T bloat. It works just fine for my needs. I don't think AT&T WiFi calling works on this unlocked firmware (I haven't tried - I don't use it).
Caveat emptor: whichever version of Oreo you choose (either the AT&T stock, or the unlocked firmware), we are stuck on the February 2019 Android security patch.
Only Pie gets the latest security patches. As long as you are ok with this, then proceed with the downgrade to Oreo!

A little off topic, but has anyone seen an AT&T security update for May yet? I'm still on April security, and it's basically mid June?
Tha k you I'll check it out when I get off work, I didn't know you could flash the unlocked firmware on a carrier locked phone
Let me get this straight. Can a locked bootloader AT&T SM-N9500U on Android 9, N9500USQU5DSD3 downgrade to Oreo? I thought this bootloader whould not let you go back.
I LOATH Pie and wan to go back to Oreo so bad, please tell me there is a for sure way. This is my first permanently locked bootloader phone and it's killing me not to flash an software I prefer.
I dont know I wish someone could tell me forsure whether it will work or not because now my phone is getting another software update notification so it's getting ready to force another update on me and I doubt after that I will still have bootloader v5. Can someone please verify whether my current bootloader (N9500USQU5DSD3) will downgrade successfully to back to oreo or not? I have the oreo firmware I want to use downloaded and ready to go which is (SM-N950USQU5CRL1). Can I downgrade to this without messing anything up?? Please I need a fast reply I dont want this new update forced to my phone and updating my bootloader to v5 where I can ever go back to oreo.

Yes you CAN downgrade back to Oreo. BUT you MUST go to a bootloader 5 firmware.

Yes you can go to that firmware. You will want to back up and allow it to factory reset. Be sure to use the modified version of Odin. Go HERE, post #2
