Downgrading intalling PG1 or previous update over PK1 latest security policy update - T-Mobile Samsung Galaxy S7 Questions & Answers

I have Galaxy S7 T-Mobile G930T (ROOTED) with latest PK1 update. Before updating to PK1 battery was lasting to 2-3 days and phone was cold all time. But, after PK1 update phone battery become lasting to only 1 day and phone sometimes getting hot by itselft. Any ideas to solve this problem? Please help me to install PG1 firmware over PK1. Phone is ROOTed.

try installing pk1 over your driver that you have right now, because i've had an issue where the security policy updated and i was stuck in a bootloop and i wanted to backup my msgs so i tried lots of things and what worked for me was to flash the ap file for pk1 with prince odin's and it just dirty flashed it, but im assuming it downgraded the policy and enabled me to boot back into my phone with no issues, but it did break my root. best of luck.
edit: try making a backup first you dont want it messing up and causing it to loose all your data

Not having any luck... (possible brick!)

So I've hesitated flashing my Sprint Note Edge simply because (and no disrespect to those that have been working hard) I was waiting on more development... but after receiving the 5.1.1 OTA update I wanted to revert back to kitkat... so I did some research and found all the files I needed to root (as well as the 5.0.1 stock firmware just in case that didn't work)... it rooted fine(I think) but when I went to add the SU superuser zip (through CMW) my Edge froze at the bootloader screen and won't go any further... I tried reinstalling the stock firmware tar. through odin but I keep getting the expected "fail"... I'm thinking my only option is to find a ROM small enough to fit on my sd card (240mb) and try to flash through cmw... but I'm not having any luck... ANY SUGGESTIONS WOULD BE VERY MUCH APPRECIATED!
I am in a similar boat here I think we need a stock odin before we can fix this so far no luck finding one on my end (
Same here too m8, on my Sprint SM-N915P. I was on 5.0.1 then upgraded OTA to 5.1.1, but had issues rooting, tried to revert to 5.0.1 thru Odin, ended with FAIL error. Initially, had the message "[aboot] Fused 4 > Binary 2". Did some digging, and now I believe my only option is to wait for the official Sprint 5.1.1 TAR or MD5 to be released or get a PIT file from someone on the 5.0.1.
Today i'll try to reflash original recovery from CF-AutoRoot's md5, so the stock "Firmware Upgrade Error...in KIES" pops up at boot, and take it to a Sprint shop, hoping for help...
That sucks! Well keep me posted on your progress....
Is it a bootloader issue or incompatibility between 5.1.1 and 5.0.1 that prevents flashing?

So im assuming i just messed up myself here

I got this s6 back in march or april and it was on 5.0.2 and well now that iv've updated to the OTAS 5.1.1 OFE i was curious about root and i continued with a thread about rooting it and etc
( i kinda regret that now, i shouldve stayed on 5.0.2)
but the main reason i rooted was to recover files and welli did but i installed dr fone on my computer it asked for my phones root permissions so i went ahead and rooted it but after a bit i noticed it started to freeze my phone and after a bit it just stopped working.
i turn it on and restart it i see a blue led cycling and i see the sprint spark screen but it does nothing from there.
and so i stupidly went to to stock recovery, wiped cache, and factory resetting it and now idk what to do
there isnt an OFE stock tar yet so i cant fix this on my own, im just thinking if i flash twrp right now and then flash a custom rom will that work?? for my OFE build
am i able to or should i just download the stock tar 5.0.2 to reflash it or will that just basically brick me completely??
also i did have insurance for this and i thnink i just blew that one too :/
ive noticed mine said this
G920PVPU2BOFE
and not G920PVPU2BOF7
so does that mean im able to use the stock firmware from the website and reflash it or like what do i do...
SO what i did countless of researching
i ended up having the
custom binary blocked by FRP lock, by forgetting to unlock oem before updating the Twisted Projects SuperSu or User since it asked me to updated i ovbiously just went ahead of myself and that happened thus into this Boot Loop Soft
and im flashing with ODIN the stock 5.1.1 OF7 tar its surprisingly working. ( i was originally on the OFE OTA tho.)
unlike the Twisted Project custom roms, kernel and or twrp setup, i couldnt boot into the twrp or even past the android screen, and well the only option i had was just Download Mode.
And this basically saved me.
Very Informative

Help, 7.0 ROOT & TWRP

How do i root/install twrp my sprint s6 edge which is on nougat?
flash this with TWRP https://www.dropbox.com/s/yk71179z29zo87h/N920_Nougat_Root_SuperSU_No_kernel_included.zip?dl=0
i tried to flash twrp twice, my phone is now soft bricked. as soon as i boot it up, there is this flash and when i touch my phones screen, it vibrates. i dont know whats going on anymore. i will now try and flash stock firmare
*UPDATE*
i have successfully flashed the stock firmware and my phone is working. The loss of data is unfortunate, but as long as my beloved s6 edge is working, i dont mind. i think ill just wait until there is a proper way to root 7.0. until that time ill just use 6.01 i guess.
Thanks anyways

which stock firmware did u use
6.0.1, G925PVPU3CPB6 from sammobile.
then i got the ota and just updated to 7.0
now im going to re-flash 6.0.1 and then cf auto root. i cant stand my phone without root.
unless someone helps me flash twrp. so that i can flash that super su file with it.
i noticed something while browsing the twrp site, it says something like "This device uses dm-verity. This means that swiping to allow system modifications will prevent you from being able to boot if you are using the stock kernel. In order to bypass dm-verity's boot prevention, you will have to install a kernel that has dm-verity disabled in the fstab". now i this verity thing is my nightmare. before when i had rot, i forgot i had used cf and went to super su and remove root. next thing i know, my s6 is in a boot loop. And when i went to boot loader it showed a message saying dm verity failed. Can anyone guide me? To flashing that kernal that is
guys ive done it. rsktkr1 thanks. i was basically flashing the wrong twrp. I will leave the link to the correct twrp file just in case there is someone who went through the same hardships as me. https:// dl.twrp.me/zeroltespr/twrp-3.1.0-0-zeroltespr.img.tar. html just remove the spaces
Thanks guys. Sorry for all the trouble.
well i got my s6 edge back and running. I had it on mm 6.0 and rooted it once more just now i decided to go back to nougat. I have found that twrp 3.1.0 sent my edge into a bootloop and actually hard bricked my phone. I figured sine my s6 flat took root on nougat that since i used the n20p supersu nand 3.2.0 twrp ran flawless with just one problem which is battery life it dont very long. so if i were to try the note versionj of my edge it might work but for custom recovery stay with 3.2

Downgrading Firmware without Losing Data?

Ever since I upgraded my Verizon S8+ to firmware G955USQS1AQI6 two months ago, I have been noticing decreased battery life (last night my phone lost 22% with aod turned off, most of the drain coming from Android System and Android OS) and more stuttering in general, which is why I have been scared to install anymore updates on my phone. I want to downgrade to the G955USQU1AQGL firmware, which was what I had before installing the crippling update. The question is, if I flash the firmware to my phone from my computer using Odin, will I lose any data? I am asking because a factory reset is ABSOLUTELY the last thing I want to do for my phone.

Yes you will. No you can't do it without a factory reset.
Backup your stuff first

[Please help!] Unable to root Samsung S7 8.0

So first off I would say I am average in the world of modifications, I know the basics. I used to run a stock Nougat rom with Magisk.
Being the clumsy fool that I am, I dropped my phone and the screen broke. I went to a Samsung service center and deposited my phone there for screen replacement and they decided to update my phone for no reason...
As my phone was rooted, after forcing an update on my phone a soft brick happened and they had to flash a new firmware which meant that I lost everything. Now I am running latest stock Oreo 8.0.
I tried these things to root my phone again:
(The first thing I did was flashing twrp through odin)
#1: Downloaded Magisk and a decryptor for getting past the locked bootloader... flashed them both using recovery (twrp works 100%), and my phone got stuck on the Samsung S7 - powered by android after a reboot from recovery. Waited for a long time. Tried a lot of alternatives on this method but got stuck..
#2 After I gave up on rooting the firmware I was given, I decided to go back on my old Nougat firmware which used to work flawlessly... so I had the nougat firmware on my computer but this time Odin gave me an error along with some red text on top right in download mode. I looked up the error and it basically meant that I cannot revert back to Nougat anymore (which is surprising as I could easily swap between Nougat and Marshmallow but I can't do the same with Oreo and Nougat)
Quote from a person on the internet: ''SW REV CK FAIL usually means that you are not flashing the most current released firmware version. Most Samsung devices will not let you downgrade. You have to flash what was previously installed or higher Android version.''
#3 I was frustrated. I tried using a last resort.. downloaded a custom rom which has root included called ''Galaxy Project''... Flashed it using twrp and got a bootloop for 2 hours. To get past the bootloop I had to download Oreo stock rom and flashed it using Odin. That worked.. I'm back on stock Oreo again... back to square one.
Please help out a stumped Android enthusiast... I have spent 2 days on this... but no solution works. My phone is not in danger of a hard brick as I can always revert to stock Oreo using Odin but having root would be nice.
I am having average experience, I know just the basics... please help me out and tell me what to do in a step by step manner.. I will try everything and report the findings till I finally come across a method which works.
EDIT: My phone model is G930FD
