Help Downgrading my S7 - Sprint Samsung Galaxy S7 Questions & Answers

Aight, so a couple of weeks ago I decided to finally accept the update that I always skipped, that pesky Android OREO (8.0) update was always harassing my notification panel and I finally decided to accept it and just update. What could go wrong?
After I updated, and saw that a few features were cool, I noticed something...
My phone was not charging even though it was connected to the charger. I tried airplane mode, I tried maximum power saving mode, I tried safe mode, I turned it off and nothing happened. It just didn't want to charge; some might say that it's just a battery issue, but I'm pretty sure that's not the case.
This happened right after I updated my lovely Nougat to Oreo.
So now I need help.
Here are my phone's specs:
*Build Number: R16NW.G930PVPU6CRE7
*SE for Android status: SEPF_SM-G930P_8.0.0_0008
*Fri May 25 20:35:22 2018
*Knox version: Knox 3.1, Knox API level 25, TIMA 3.3.0
*Security Software version: MDF v3.1 Release 2, WLAN v1.0 Release 1, VPN PP-MOD v2.1 Release 1.0, ASKS v1.4 Release 180123, FIPS BoringSSL v1.2, FIPS SKC v1.7, FIPS SCrypto v1.0, SMR Apr-2018 Release 1
*Android security patch level: April 1, 2018
*Model Number: SM-G930P
*IMEI: 353562085155911
*Software version: G930PVPU6CRE7
*Hardware version: REV0.6
*Android Version: 8.0.0 Oreo (I want 7, Nougat)
*Samsung Experience version: 9.0
*Baseband version: G930PVPU6CRE7
*Kernel version: 3.18.71-13585094, [email protected] #1
My phone is a SPRINT unlocked version, 32 gb. You can check out those specs; probably understand them a lot better than I do.
The thing is, I know that I'm going to have to root it in order to install a previous Android version (downgrade). I just don't want to take any risks with flashing the wrong firmware for my specific phone; I don't want to brick it.
So, can y'all please help me with choosing the right -my phone specific- firmware and stuff?
Giving me a step-by-step on how to successfully downgrade back to my 7.0 nougat would be a blessing too.
Thank You!

I cannot believe the charging problem is caused by Oreo. Try different chargers, and new USB cables. Google the issue to see if it's related to Oreo. If you are absolutely sure this is due to Oreo, then you may change it and root is not required.
Since the phone is still on bootloader 6, you may be able to downgrade to Nougat with the same version of bootloader. Flashing firmware is a complex process and phone may be easily bricked if anything goes wrong, so you need to understand what you are doing exactly. I would suggest to read thoroughly information related to Samsung Galaxy firmware update using Odin software. I usually get s7 firmware from two sites:
https://updato.com/
https://www.sammobile.com/firmwares/galaxy-s7/

Switch off your phone then try charging?

Well, ironically, my mother got a new -android- phone a couple of days ago and my phone charges pretty fine with her charger. I guess it WAS a charger problem, but my charger works perfectly fine on my father's phone and not on mine; strange.
The thing is, although it can now charge, the super battery drainage is still there, and yes, I'm convinced the quick battery drainage problem came along with the Oreo update. It lasted hours and hours on Nougat, but now on Oreo it barely gets to 3 hours and 30 minutes.

I have tried any and all 1 clicks i could find, attempted all old hacks i have from older root methods.
The only things i haven't tried are
• Exploits i did not find searching past 2 weeks every night for hours
• Anything that downgrades any software on phone
• Anything that installs custom recoveries
I am willing to downgrade and use an app like towelroot if it is possible, but with my firmware being from 2015, i'd be worried in following any downgrade methods (what few i have found for this phone) since none of them mention the ability to do it w/oa1.
to be honest, with such limited support for this phone in Google (especially since a 2015 kernel) I'm kind of scared doing anything major with it =/... I got the phone about 2 weeks ago, and have been trying to root it from day 1. The phone was a $0.99 phone from cricket to bribe me into staying with them( they just changed to GSM and screwed everyone over who had purchased a new phone recently, another story for a never to talk about time)
I would prefer to not trip Knox, but if it's a must then.... well... it's a must, isn't it...
any and all help would be highly appreciated.

Help unlocking, installing stock ROM on an S5

Hi, a friend has a Galaxy S5 (MetroPCS) he wanted me to unlock. He works at a hotel and any items found in rooms go to their "Lost and found" thing for a 60 day period. This was found and never claimed, so he wants to use it as his own. I've looked through it a bit and it appears it was used by a former drug dealer around town. Huzzah. Anyway.
It appears to already be rooted and has TWRP already installed, though still uses the stock ROM.
My questions are- How would I go about doing a fresh install on it? Also, is there a free way to unlock them or do I have to go through one of those unlock websites?
Here are the specs

I see there's a newer version with 5.1.1. Would I be able to flash that without any major issues instead of the one already on it?

Upgrade it using Smart Switch.
Just an update- I successfully used SmartSwitch to upgrade the phone, kudos for that.
Also ended up going through cellunlocker.net to unlock it. They even sent an unfreeze code with it.

Galaxy S5 SCL23 (SM-G900J)

Hello.
I just recently got Galaxy S5 which appears to be only sold in Japan. There's some custom firmware installed on it which prevents Android to be updated. Phone doesn't have SIM locked, so any SIM card can be used.
Because the forum doesn't allow me to post link to a screenshot which shows firmware info I'll just write it down.

I'd like to completely wipe this firmware from the device, replace it with the latest Android version (6.0?) and root it. At first I'd like to know if it's even possible to do any kind of firmware changes on this model and what exactly do I need to perform the update/root.
Thanks.
Doesn't look like there is a 6.0 stock ROM for it, but you can upgrade to 5.0 here
http://updato.com/firmware-archive-select-model?r=&v=&q=SCL23
Flash with ODIN (Instructions all over the forum many times)
Okay, instructions on updato seems quite easy to follow so that shouldnt be a problem. Is there any recommended tool for root? I've found a lot of them and I really don't want to mess something up.
PS: How come there's no stock ROM for 6.0 even tho it's been mentioned in some articles that SCL23 model is also supported by Marshmallow update?
Anyone?
Okay, update to 5.0 passed without any issues. There are some default japanese applications on the phone which I cannot uninstall, is it possible to get rid of those somehow?
I have the same device Do you update succeeded or not

Go to this link & download 4.4.2 then follow this tutorial.
Make sure to use key input from the options & use capital letters where needed. All being well you will have everything working again.
Make sure not to use any download manager for the download link. File gets about 100kbps so it'll take a few hours but you will get it.
I did the above then rooted the phone & flashed correct TWRP version to it then flashed 5.0 Lollipop SpaceX rom here. Everything working good & no loss of service on reset or reboot.
Hope it helps

Ready to root: Variant AT&T SM-G935A

Hoping someone might be able to share the latest with me , on what I am sure is a well-covered subject by now. I am familiar with ODIN panel from around 8 years ago, so I assume I will have to download both a working version of ODIN panel, as well as Root, TWRP, Recovery, and ROM, zips, and then use ODIN to flash the phone. It has just been a while And I am looking for a walk through, and links to the stuff I need. If' ChazzMatt is around maybe I can benefit from his mighty knowledge.
Thanks!
P.S. will rooting also kill the insistent SecurityLogAgent message "Unauthorized actions have been detected" message from returning as well?

Galaxy S7 Edge SM-G935A Root...
I would also like to know how to root my Galaxy s7 Edge SM-G935A from AT&T. I've been looking with no success. I was hoping to upgrade firmware to either Lineage OS or Exynos but it's looking like this might not be possible due to the chip AT&T used not being flashable or something?
I was hoping to at least have root access in order to use some apps that require root. Lots of stuff for other G935_ phones with other carriers
Hope there's some replies... Thanks

Can't do custom ROMs since Snapdragon 820 bootloaders are locked down well, and haven't been unlocked to be able to flash a Custom ROM AFAIK.
But I do think you're able to root? Just know it will probably 'Trip your Knox counter'. I think you can use CF Auto-Root to to root it

How To Downgrade Moto G5 Plus?

Hey everyone,
I've spent time looking through the forum, but I just can't make sense of all the info on how to downgrade the OS on my phone to Android 7.
I need advice on the steps to take in order to downgrade and avoid problems.
Details:
GSM Unlocked
OS: 8.1.0
Current Build Version: OPSS28.85-17-6
Security Patch Level: Feb. 1, 2019
Hardware Information:
SKU: XT1687
Version: PVTB
It's been a headache ever since I've updated my phone--freezing, apps quitting... yea, you name it. Reset it to factory settings, but no improvement. Wasn't a problem before the update and I know OS updates can burden the hardware.
Been a lurker here for a while and you all have been a great source of help.
