[Q] how to downgrade lollipop to kitkat?

Hi. I have recently updated my note 3 N9005 Lte from Kitkat 4.4.2 to Lollipoo and also updated the BL,CSC,CP AND PIT File. Now is it possible to downgrade it back to Kitkat firmware? N9005XX...B7 BTU version ?

It's pretty simple.
1. Do the factory reset
2.Install KK via odin
3. Enjoy your KK
It worked for me on GNG1 ROM

I wouldn´t risk to do it like this. If you have updated the bootloader, I think you can´t just flash the KK via Odin. If you have updated the bootloader, there is no back to roll back. If not, you have still a chance.

flashing leaked KitKat
hi,
what about to flash the leaked KitKat which contains all the files needed for Odin, including bootloader? What do you think about it guys?

do upgrade with odine?????

I tried downgrading using the Leaked Polish KitKat to no help.
First tried to downgrade using the original Australian one. It failed by Odin.
Then tried with a .PIT file and the corresponding Germany firmware, didnt work either. Phone wasnt even switching on, gave some error saying firmware update went wrong, connect to Kies... or something similar.
Just to see I reinstalled the Lollipop, It worked just fine.
Then saw about the Polish KitKat leak with all the BL/CSC/AP and all files, downloaded and tried.
For my joy, It installed just fine, but my joy ended when I booted into the OS, it was all buggy, network not working, constant app crashing, camera fail, and made me really scared when It showed that my IMEI number is NULL!! I thought Im so done....
Then tried the German KitKat with the Polish leak's Boot Loader (BL) file, it failed too.
Since I was so worried about the phone getting address-less (No IMEI, no other addresses) I tried reinstalling the Lollipop leak.
It worked again like a charm, and my IMEI n everything else is back.
So looks like Ill have to wait till we get an official Lollipop update, so I can get out of the leak.

Downgrade to Jelly Bean Instead!
KitKat is bogus‼
Really, downgrading to JB is worthed it!

I'm sorry, I don't know how to check whether the bootloader is updated.
Btw, Stallione, when the IMEI is gone, you can restore it from EFS backup

No WiFi or Mobile Data After Unroot

I recently decided to unroot my Galaxy S4 SGH-I337 from AT&T using the methods and the downloads from this website here: http://www.androidrootz.com/2014/03/...xy-s4-sgh.html
Now, when I turn my phone on, neither my WiFi or my mobile data will work, and if I try to turn my WiFi on, I get a popup from Security Information that says "This device has detected an application attempting to perform actions that are not permitted. These actions have been blocked.
I've tried pulling out the battery, I've tried turning WiFi power save off from the dialer menu, but neither one has worked. Not to mention my device is so old now it's probably out of warranty. I'm not really sure what to do from here.

The unroot app probably screwed up your kernel. To unroot your phone you do not need another app. You can do full unroot from the SuperSU setting.
Please tell us your phone android version, Bootloader version, baseband version , etc..
Please backup everything. You might need to flash just a kernel or just a modem or full rom or full firmware.

I'm running 4.3, I believe my bootloader is I337UCUEMK2, the baseband is I337UCUFNB1. Do you need to know the kernel version?

If I knew the kernel it would help. You have jelly bean bootloader with kitkat modem. It appears that your kernel and modem are not communicating after the unroot.
It could be fixed by flashing the kernel and if it is not work or it would give you the softbrick, you might need to flash the whole firmware.
There is MK2 firmware on this forum. However, yesterday I was helping someone who has the same problem as you do and the MK2 firmware did not work. He had finally to flash the NB1 firmware to work again.

That is exactly what happened to the another person that I mentioned in my previous post. If you go read that thread you will see it.
You and him has the almost the same problem and I think you will need the same solution.
I could copy and paste what I said from that thread. But please go and read that thread and follow the instructions that I posted there.
If that is not solved your problem we will think of another route.

I have tried multiple zips to try to get the U software on my phone but always ends up not booting. It will show galaxy S7 and then boot straight back into recovery.
Can someone please provide a link to the exact download files I need. Sorry to start a thread over this. I'm just having a hard time finding the correct files. Thanks in advanced.

Anyone?

It should be as (simple) as..
Rooting your phone -> https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039 (this won't trip KNOX)
Downloading the proper firmware from SamMobile -> https://www.sammobile.com/firmwares/database/SM-G930U/
Flash the firmware via odin (you can use the same method found here: https://forum.xda-developers.com/s7-edge/how-to/official-stock-firmware-update-odin-t3335065)
Profit
I just did this recently to switch from SM-G930R4 to SM-G930V
Note, you will lose all data on the phone if you try this.

Go to Updato.com and get the newest SM-930U firmware from January and flash via Odin. The 930U firmware you flash must have a bootloader the as or newer than your current firmware or it will not boot. You do not have to root to update via Odin.

Less boat , no Verizon boot animation, and my favorite the spam dialer Verizon thought was a good idea to remove. I like to think of the U as pure Samsung vs the Verizon gimped software.

Is the bootloader unlocked? Is there any down side? LTE performance etc? Can this still be done if I loaded the Nougat beta on my G930V? Thanks in advance.

Bootloader is locked because it is a snapdragon variant. Only downside is can think is you would have to pay your bill in store or on a PC. Lte seems the same. Yes if nougat is on. You just load up the most recent U firmware and flash over nougat in odin.

it shoudl be simple...but it failed for me in one of my two phones. now it keeps going to recovery (downloading the original firmware to reflash it). the one that worked was a SMG930VZDA (made in vietnam) while the one that didn't is a SMG930VZKA (made in korea). I hadn't updated either one from the original firmware, but not sure what firmware they came with....
so if it works, it's great, but if it fails...

You can still use the My Verizon app to pay, if you want to. You do lose Verizon's native VVM app, but there are workarounds to use Voice or another third-party VVM app (I personally use YouMail).

Hey your right! One less hassle.

Hi everyone,
I recently purchased a new g930r4 (US Cellular) because my last samsung got stolen. Anyway, the first time I turned on the phone, I started having multiple issues (kept rebooting, unable to recognize headset, kept freezing). Then I decided to change it to the g930U firmware and I noticed a HUGE difference. I totally recommend this to anybody that has same problems I mentioned. Thanks to all the information from this post, I was able to successfully flash the firmware. Thank you all for the support! I hope this helps someone out there whos still got some doubts.

Hello, I have the SM-G930V Snapdragon variant in the US and I would really like to root it to get a custom ROM. If you wouldn't mind, I'd appreciate a reply (if you have one) to this thread I made on the topic: https://forum.xda-developers.com/verizon-galaxy-s7/help/questions-bootloader-rooting-custom-t3721109

Most probably the reason for that is you can't downgrade, it seems your bootloader is newest and can't be downgraded back . This is most obvious thing

As u seen it u can't go back via official way. Stay on latest stock without root ,no other way I'm afraid
Good luck

Galaxy S8 Fails to Flash Firmware In Odin 3.13

I'm trying to downgrade the software in the S8 to android 7 so that I can root it (root methods that I tried for android 9 haven't worked) and when in Odin, the original software fails to flash, I've tried a couple different AP files for my model and they all fail. Any suggestions?
Any help is appreciated.

It fails because you cannot downgrade bootloader, hence the Odin fail at boot.img. you must flash the current or newer BL unfortunately. Have you tried to flash twrp + magisk for root?

The effort put forth by Extreme Syndicate is great except some of the disclaimers aren't promising.
This method will work if you are on Android 9 Pie but will put you on Android 7 nougat. There is no root for Android 9 Pie
You will not be able to use normal magisk
You will not be able to flash custom rom like Lineage or any other AOSP roms
You cannot flash custom boot images or recovery images such as TWRP
The whole reason to root, in my case - any way, is to put a custom recovery on such as TWRP and then flash a custom ROM to get rid of the **** Samsung provides.

In my case, I just downgrade to 7 nougat rom, then couldn't do much, so I got to think. I just wanted to revived this sucker!
Plug it back to odin and reinstall the lastest firmware from sammobile.
I'm not an expert on any of this, but like a said just bringing back this sucker, im in peace.

I can't stand Samsung's software so I'm "glad" in the sense that I bought the phone for experimenting and not to use on a daily basis because if I had to use One UI daily I'd descend into madness over how much I can't stand it.
Having said that, attempting to root it, put a custom recovery and rom on it are very frustrating tasks when Samsung's Knox and other code gets in the way to the point of everything in Odin failing.
"Food for thought" - How can your device be "your" device when it clearly and evidently locks you out of doing whatever you want on it?
I'm not sure if there is a community for anti-bloatware but if there is I'm just as much a part of it as I am with right to repair.
