Hi i have an AT&T S6 and it has the baseband EQF1. I want to downgrade to marshmallow which baseband do you recommend?
I have tried to downgrade from nougat but the only problem I have had when I've done so is that the baseband is unknown and I have no cell signal so now what I've done is I flashed marshmallow but I have the baseband for nougat is the only way I've been able to get cell reception and to have the baseband to show up
After I've done all this I cannot get back to full nougat when I flash a stock nougat firmware using Odin it will just hang at the user data I've even let it go overnight and it never moved off of user data but I am just happy to have the phone working and hopefully I can find a fix for this
What is your security version, you must flash same. 5 to 5 or 6 to 6. i'm assuming you're 6 but since you didn't put in the your build we can only guess.
please provide us with more information so someone can help you. such as the current build number of the phones as found in settings or recovery
and what version of odin are you using? 3.12 has always worked fine for g920a for myself.
Its version 6 can you give me a link for it

My Nexus 6 received 7.0 update notification and I would like to wait for 7.1 to upgrade together. But yesterday the 7.0 notification suddenly gone, I've manually check the update but the system said my phone already get the latest update. Then I've checked the version of my Nexus 6, it is MOB31H, I don't remember whether I have the November update. Now I have few questions and hope someone can help me.
1. Why the 7.0 update notification suddenly gone?
2. I've checked the Full OTA images, the Nov update contains MMB31C and MOB31K, If I would like to manually apply the update, which one should I use? (My Nexus 6 is international version XT1103)
3. If i manually apply the the Full OTA Images on Nov update by adb sideload, will all the data being erased and need to re-config and reinstall all apps?
Thanks so much in advance for your help.
1. Unknown
2. Your device model doesn't matter as the OTA zips work on both, but based on the model number you gave, you have a US device. The international unit is XT1100. Use the version with the code ending in "K" if wanting Android 6.x. Android 7.x uses codes starting with "N".
3. Flashing an OTA zip will not cause loss of data.

Thanks so much for your help, I think I mis-type the model, XT1100 international should be correct.
I've just sideloaded the version MOB31K successfully and will wait for the 7.1 fix on the speaker phone echo problem before upgrade to 7.1.
Please don't mind to ask one more question, i guess the MMB31C and MOB31K is for US and International model respectively. On version Nougat, no different on XT1103 and XT1100, one version for both model?
Thanks so much again for your help.
Or you could sideload NBD91X, which is Nougat without the speakerphone problem.
@mega23mac: MMB31C is for CDMA devices in the US, if I recall correctly. As @dahawthorne points out, you could install a 7.0 OTA, but if you don't need the speakerphone, the 7.1 OTA works just fine. Google should have it patched for next month's security update.

I had this exact problem with SM-G890A on 6.0.1. I flashed a stock firmware, and I had no mobile network, sim card wasn't detected, etc. The problem was that my device had the most recent update (from March). I am not an expert, but I believe this update makes it harder for devices to be susceptible to flashes (hence "extra security"). To fix this problem, after flashing a stock firmware, I put my phone in recovery mode (volume up, power, and home) and downloaded ADP, and from there, I was able to download each update after my stock firmware until I reached the update that I was on before I ever flashed. I hope that makes some sense. There is a great post on here with the updates available for download and instructions on how to use ADP. I wish I still had the link, but try searching the updated version that you should be on. Whenever I finished the last update and my phone restarted, I restarted it again in recovery mode and cleared the partition cache. Restarted it again and VIOLA, I finally had service. Feel free to email me if you have any questions. Sorry, I am not great at explaining things. I hope you can resolve this. [email protected]
Fixed and Downgraded
I had this same issue. I was able to fix it by first upgrading back to 7.0 as mentioned above, and then flashing ONLY the BL and AP files of the 6.0.1 firmware using Odin. Worked for me.
U need flash to android 6.0.1 build Pk8.

Hey I had the same problem as you and I was panicking. I downgraded to 6.0.1 from 7.0 final version but the SIM/IMEI/Broadband/anything phone related was broken. What happened was the final build of 7.0 upgrades the security of the SIM/IMEI/Broadband and so if you flash any other firmware, it won't work with the newer security and it'll remain unknown. To fix this, you have to upgrade to 7.0 final build again. Just adb sideload all the way back to 7.0 final QD1 and your SIM/IMEI should activate again. I guess ATT/Samsung is preventing us from downgrading just like Apple
Flash the Nougat Odin package.
Hello!
Here is the full G925VVRS4DQD1 Odin manual update to 7.0 Nougat for everyone to enjoy. You can flash from any current version you have now it doesn't matter whether you are on 5.1.1 or 6.0.1.
https://www.androidfilehost.com/?fid=529152257862722630
If for whatever reason you want to downgrade or don't like 7.0, you can safely downgrade to any of the below versions without any issues. After you flash a lower android version using Odin, phone might get stuck on Verizon logo. If that happens, all you need to do is boot into recovery and do a factory wipe/reset and phone will boot right up after that.
G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500
G925VVRS4CPL3 (6.0.1) - https://www.androidfilehost.com/?fid=673368273298921946

@toutanje Out of curiosity, how did you determine which builds you can safely downgrade to from 7.0? Is it something you personally tested or did someone recently go through the hard work and post their results somewhere? BTW, you can now add G925VVRS4CQA3 (6.0.1) - https://www.androidfilehost.com/?fid=529152257862700500 as two people have confirmed downgrade success here: https://forum.xda-developers.com/verizon-galaxy-s6-edge/help/downgrading-nougat-t3601096 . One used firmware from sammobile and the other directly from the link above. This is the very last build available for Marshmallow.
Hi there. I installed the new update on my s6 edge 7.0 via verizon software updating tool.am noticing the sound quality of mt s6 edge has been changed.before the sound quality was thick and now its not that thick anymore.i want to bring back the thick quality sound on my s6 edge.there is setting called sound quality and effects but i cant manage to get back that sound quality i had with 6.0. Is there anyone who able to notice this change in the sound?

With a very a simple observation, no testing or anything needed
G925VVRS4DQD1 <-- you see the 4 towards the end of firmware build? That is the revision bit number. This means you can flash ANY firmware for that model with a 4 or higher. Take this 5.1.1 firmware for example ---> G925VVRU3BOG5. Even though this firmware is also 5.1.1 like the ones from above, this particular one will NOT work because it is on an older firmware revision bit (3).
The same is true and goes for ALL Samsung phone/tablet models and firmwares.

That is very good to know. Yeah I noticed it about the firmware naming convention but I had no idea what the value means (or the character before revision bit, U has become S). My phone out of the box was on G925VVRU3BOG5, so I guess I could go all the way back to G925VVRU4BOG7 if "needed" lol.
One of my fears about Nougat is about all the work they did to automate and place updates into the background. This could allow disabling of downgrades, or anything else at the discretion of Samsung and/or the carrier. I think this has already been done in Marshmallow, just on a smaller scale for security fixes. Anyway, it seems to me like an attack vector waiting to happen: less control over my phone combined with an easy way to break things. Imagine all the troubleshooting fun we will have.
So I upgraded to nougat. I'm having battery issues and just want to go back to marshmallow. but I'm having problems. The nougat rom installs just fine with odin. But when I try with any of the 6.0.1 roms it was failing. Then I noticed that re-partition was chcekd. So I unchecked it and now it goes through the process just fine. But now the complains with dm-verity verification failed. I can install nougat on it no problem. It's just the downgrade that's not working... any clues?

I actually managed to get the N925V to downgrade all the way back to the firmware version G925VVRU3BOG5.. May have cost some money for some very specific files but my phone's back on G925VVRU3BOG5 and it's really only a test phone for someone I do work for! I have it rooted with SuperSU and not kingroot and I created a script to keep the phone set to "permissive" so it's able to do full reboots and not just hot reboots using xposed... Unfortunately it seemed like no one cared about it when I posted it in the other thread so it's probably not worth it to a lot of people but I think it is with the amount of fine tuning I did to get it to where it is today!!

Mike! Can you explain how you did it? I'm stuck on nougat. Every time I try to downgrade, I get the dm verity error. I've tried all the 6.0.1 version and the 5.0.1. No luck . I'm back on nougat. Can you please let us know your process... Thanks!
Did you have to select anything special in the options? I just left it at default which is Auto reboot & F. Reset Time.

I mean I could but I had to shell out some money for this firmware and I don't even know if you can flash it with odin because I don't use odin I bought a box to do my flashing since I work on so many phone's and odin just doesn't cut it.
No Worries. Finally figured it out. Good luck to you

I was able to use this to flash my Samsung Galaxy S6 Edge from 5.1.1 to 7.0.
Not that I want to upgrade again, but is there a 7.1.2 available? Is there a routine schedule for that sort of thing or was the 7.0 Nougat think kind of a special case?
Thanks!

I haven't been keeping up, but now curious. Verizon shows DQH1 as current (a 7.0 build), while sammobile and androidfilehost show four builds available (all 7.0).
Ok, so I updated my G925V with nougat, now I'm just wondering if anyone has come out with a way to root this build? That's what I'm waiting for. Plz fill me in when that happens. Thanks.

I use the Z3x box and Octoplus box I have 2 of them for different phone makers but I have so many different wire connectors that I lost count because what works on Samsung doesn't work on LG, HTC etc etc.. You can find them pretty cheap but I'd avoid buying from eBay because of to many scams selling broken or bad boxes that can't be activated.

You unfortunately cannot downgrade the bootloader once you updated to 6.0.1 you lost the ability to go back and there's so far, no way possible to do it.
Hey everyone this is my first post and I'd like you all to help as much as you can.
I've had this Note 8 for a little over a year. The current carrier it has is T-mobile. I've notice there are new updates to the note 8 models but I'm still on Android 8.0.0 and Samsung Experience version 9.0. Everytime I go to the settings and try manually update it the message always says my phone is already up-to-date.
Please help.

Sometimes a factory reset can resolve OTA's, just make sure to back up all your data beforehand. You could also download the filmware from Sammobile or updato and flash it with Odin to update it to the current build, using the "homecsc" file will keep your data.

Download this firmware and then use Odin to flash it and if you don't want to lose any of your information that you already have in there, in the .zip folder after you extract it once you'll see all the files you need but there will be 2 CSC files only use the one that says HOMECSC if you use the other one it'll factory reset your device so don't use that one. Make sure you also download the latest version of Odin.. Firmware for download link is https://androidfilehost.com/?fid=4349826312261709167

Hi All,
I urgently need some help to downgrade Samsung Galaxy Note 9 phone Model No: SM-N960F/DS from currently running OS Android 10 to Android (Oreo) 8.1 or 8.0.
Following are the current versions running:
Software version: SAOMC_SM-N960F_OXM_XSA_QQ_0016
Knox Version: Knox 3.4.1, Knox API Level: 30, TIMA: 4.10.
I have downloaded the XSA version of Android 8.1 from Sammobile, followed all the instructions by running Odin3 V3.14.4, gone into the Download mode of the phone. The phone connects to Odin as I can see on Odin status of Blue Colour Com connection established, Odin then displays "Recovery", unfortunately the phone gets stuck at this status showing "Recovery". I have let the phone run for hours or even a full day but the status never changes from "Recovery"
Could anyone please assist me to complete the downgrade. Am I missing any step here?
Thanking you in advance
I don't think downgrade to oreo is possible. Pie is possible if baseband version's 5th character from the back is 4.

Thank you for the prompt reply. I just check the digit, its 6 not 4. What are my options here?
None. Your options are only firmwares with the number 6, which date to April/May, last OneUI 2.0 firmwares.
I did read that one can flash custom roms that are older, if one leaves Bootloader untouched to v6, but that is something i wouldn't encourage to do.

I have no links except the Development board here, my input came as something that i've seen discussed somewhere in there.
As you can see, there are some Oreo Custom ROMs, i'm not sure if they are actively maintained (if one can say anything active about that), but if you are determined to do what you want, i would start by choosing the ROM first, put a question there or the last resort, contact the developer.
I'll be very blunt with you, i see no reason for people to revert to older roms, but i dont want to get in to that argument, but having a v6 Bootloader (and maybe Modem too) with a v1/v2 system firmware is something that could give you unpredictable issues nobody could help you with.
Could boot a pie custom rom with android10 bootloader. Not sure about oreo though
