My older phone was a Sony Z3 which i had root running without any issues, but i recall it required the phone to be downgraded into a specific firmware.
I just got a Samsung S7 Edge (Exynos), I was reading up on how to root the device and install TWRP on the office thread. here : link
Can i just follow that thread's video or do i need to downgrade something on my phone before hand.

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.
Android version:
4.4.2
Baseband version:
SCL23KDU1BNE4
Kernel version:
3.4.0

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
I installed Android 6.0.1 and the network was missing help someone Galaxy scl23 or give the firmware 4.4.2 or help to find the GSM network

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
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/

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.
how to degrade, s7 edge G935U ROM G935UUEU9CSA3 androi 8.0.0 to G935UUEU4BQD2 android 7.0, without that odin error of boot v9 binare 1.
please help ... that android 8.0.0 I spent a lot of battery
If you could pop it open and directly connect to the flash memory, you should be able to directly overwrite everything. An older motherboard that hasn't been updated is another option. I'm sure $1500-$2000 might also get someone to come up off an engineering build without the revision check.
Those are my only ideas. The last one there about revision checks is best option without opening the device. I had engineering firmware for the note 5 that let me downgrade the bootloader to an older revision. I could have almost done a full on complete downgrade from revision 3 to revision 2 except for "param.bin". Download Mode itself was the only thing not downgrade-able in that instance.
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
Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQC9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates. Every time i try to update it says that its up to date.
I have tried different ways to update it that i read online, The latest one that I have tried is following the steps given from this Thread https://forum.xda-developers.com/att-galaxy-s8+/how-to/sprint-released-oreo-s8-s8-flashing-t3915872 but it gave me this output https://prnt.sc/oqjnp6
My phone is not rooted or anything just a normal phone. I am just trying to update it to the latest Android Version 9.0(Pie) , I just made this thread for the reason of maybe someone can help me on updating my phone.
Where you able to update it? Or are you still having issues?
