Okay, so it seems that this firmware has root access enabled by default, as "su" is locate in /bin/su of the rootfs.img. This means that we can pull images from the device and flash custom images once we figure out how to either port Android Wear over or build TWRP!

I have a ZTO S3 Classic, is it possible to change to XSA flashing this file? I wondering because here in Brazil we have SPay on our Smartphones but not on the Smartwatches yet
@dxzdxz1
Please be carefully...
At the moment I saw 2 devices "die"...
Better wait, if repair is possible "at home" in worst case scenario...
Otherwise you can brick your Gear Wearable... then WiFi not work to connect with device... Odin...
Only as hint.
OWN risk!

Watches die after downgrade Tizen version.
Don't flashing APK3, APK7.
Download only same version BQC2 non-combination or any combination firmware.
Code:
Watches die after downgrade Tizen version.
Don't flashing APK3, APK7.
Download only same version BQC2 non-combination or any combination firmware.
So it looks like again sboot Bootloader is not downgradable... except Combination files downgrade Bootloader (sboot.bin)...
Hmmmm.
Any idea how to detect Bootloader Version on Wearables?
On Tizen Mobile I can see it in Logfiles...

I can only find BQC5 firmware to download (for free only the APK6 and APJF)
I imagine that BQC5 will work in this case, but could you confirm to me?
About the CSC reset, after make this CSC Reset thing, would be possible to change my CSC region? It would be awesome if we could change to XSA or any other CSC where SPay works.
AGAIN WARNING!
Be VERY very carefully with these Combination Firmware...
Today 1 user told me via PM...
He is successfully on Combination Firmware... BUT Wifi option is not available for use with WiFi Odin...
We have no solution yet, how to connect without damage device... to USB cable...
OWN RISK!!!
Risk to "softbrick" and/or you are NOT able to flash other Firmware again...
Only as hint.
Best Regards
Please, need info/confirmation.
If Combination Firmware writes older sboot Bootloader aka downgrade...
This should be possible to test with SDB and this Command:
Code:
cat /proc/cmdline
Thanx in advance.
Best Regards
Any newer version ?

This means """Combination""" Firmware...
If you not know what it is.
NOT use it.

This is NOT normal leaked Firmware...
Samsung NOT share Gear S3 Firmware...
Only official Firmware updates are over the air... called FOTA...
Odin nor Net Odin nor WiFi Odin...
These are all leaked stuff...
Odin is Service Tool for authorized Service Partner... NOT for public...
Firmware is also leaked... from Service Partner...
Combination Firmware are special Service Tools... NOT for public... NOT for End User.
Again, if you not know what you are doing...
Better not try...

Maybe then more clear what Combination Firmware can do...

I bought early Korean import of gear S3, but I live in US. I did not know SPay would be shut off. Very annoying. Now looking to flash stock ROM that matches my region. I understand this is a common issue.
I have been away from flashing for a long time, but if I understand the information in this forum correctly, flashing a new ROM will automatically cause the S3 to update its region internally. However, downgrading your Tizen version will softbrick the device.
I have SM-R770. Tizen Version 2.3.2.4. Software version BQ--->D<---2. I should NOT attempt to flash this BQ--->C---<2 ROM for risk of softbrick, is this correct?
Please confirm. Thank you!

This is IMHO not correct.
Country/Region aka CSC change require special procedure... with Combination Firmware.
This happens not automatically...
Product Code is stored on device in """"protected""" area...
It is not impossible to change Product Code... but is not easy with Flashing via Odin...
Software version BQ--->D<---2. I should NOT attempt to flash this BQ--->C---<2 ROM for risk of softbrick, is this correct?

Yes, in main correct...
This Security crap is Bootloader related... sboot.bin...
As Info...
These Firmware packages are 1:1 from Samsung Server...
In theory, if you remove sboot.bin and cm.bin... it could be more safe to flash older Firmware...
THEORY, not confirmed yet for Gear S3
I am doing this only with my Gear S2... SM-R732...
...risk of softbrick...

IMHO it is closer to Hardbrick...
As Security disable wireless Download Mode...
To solder 4 wires to PCB... to have USB cable...

Hi guys,
I was hoping someone could help me out. I have rooted before (long time ago) but I can't seem to find a lot of information on this specific phone (SM-J727S). I have been searching online (and across many dodgy looking websites, thanks No Script!) and this is about all that I have found:
The Galaxy J7 is also known as the Galaxy Wide 2 in South Korea
http://pdadb.net/index.php?m=device&id=11601&c=samsung_sm-j727s_galaxy_wide_2
It was released on May 2017, runs Android 7.0 (Nougat) and uses the Exynos chipset
TWRP has a release for the J700 series but I'm not sure if it would work on the J727S
https://twrp.me/devices/samsunggalaxyj7exynos.html
The source code for the system has been released, but I couldn't find a stock ROM (which made me reluctant to try TWRP)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=j727s
This is the closest I got to a Stock ROM but I don't trust the site, is this site trustworthy? (again, I came across too many dodgy sites to just download anything)
https://stockromupdate.com/2017/07/26/stock-rom-sm-j727s-samsung-galaxy-wide-2/
The KingRoot method currently will not work and is asking me to wait for an update (phone is probably too new to root?)
The closest thing I can find on this forum are these posts (but none reference the J727S model)
https://forum.xda-developers.com/galaxy-j7/development/root-sm-j727p-galaxy-j7-perx-td-lte-t3611202
https://forum.xda-developers.com/galaxy-j7/help/root-sm-j727p-galaxy-j7-perx-galaxy-j7-t3598117
So, I'm hoping someone could point me in the right direction. Thanks in advance
I'd thought I'd mention that the bootloader is unlockable in this phone. I had read elsewhere that other people cannot access the 'OEM Unlock' option on their version of the J7. It isn't the case with this phone
https://forum.xda-developers.com/galaxy-j7/help/galaxy-j7-pop-galaxy-halo-t3647805/page2
I also got a message from Google talking about my accounts being accessed by a 'J7 Pop'. I guess the Galaxy Wide 2 is also known as the J7 Pop?
So, I'm still on the track of rooting this device. I'm just gonna update any relevant stuff here.
The closest TWRP that I can find is for the 2016 version of this phone, it has the same Exynos chipset.
I'm thinking of trying this, but are there any problems with flashing the wrong version of TWRP? (Will I brick the phone? Or will it just error-out on recovery and boot normally?)
https://twrp.me/devices/samsunggalaxyj72016exynos.html
I also found (what I believe to be) the Stock ROM for this type of phone, you have to sign up to the site in order to download it. It is specific to SK Telecom (Korean telecommunications provider)
https://www.sammobile.com/firmwares/samsung-galaxy/SM-J727S/SKC/download/J727SKSU1AQD6/172065/
If someone can advise about going forward with the similar TWRP version I'd appreciate it. Cheers!
EDIT: Kinda answered my own question, from the TWRP download page https://dl.twrp.me/j7xelte/
Downloading an image for a different device, no matter how similar, usually does not work.

Any way to request an TWRP version?
I am Korean, and it's very hard It's angry me............................
XDDDD I'm from South Korea too and the J727S is customized with the Knox Enrollment Service that blocks the wifi and cellular data AND apk installization. (trying to uninstall it )
I found this: https://www.androidinfotech.com/2018/02/root-samsung-galaxy-wide-2-sm-j727s-nougat.html
anyone habe twrp for this model ????
Hi.. I've this model also.. tried to downgrade..but it can't..always failed
My friend was installing the twrp to root a J7 metal.
Now the cell phone does not restart, and I do not know what the **** it did KKkkkkkkkkkk
It wants to remove the twrp without formatting the device.
If installing the original rom by Odin using home_csc does it return to normal without formatting?
Restore

How to downgrade a non-rooted S7 Edge from Android Oreo 8.0 to 7.0 and keeping your Knox 0x0!
So if some of you are looking for a 'how-to' guide, look no further! (I believe it works on your S7 too, but make sure you have downloaded the correct firmware)
*IMPORTANT*
-I don't take ANY responsibility if you bricked your device during the flash!
-Follow the guide below before flashing your official firmware using Odin!
On the phone
-Sign-out any accounts on settings
-Have OEM-unlock & USB Debugging ON (developer options)
-*optional task, just in case* Screenshot your device information on the settings tab (IMEI, Baseband, Software Info, Model number)
-*optional task, just in case* Backup your device using Samsung SmartSwitch software
Things to download
-For this guide I used Odin v3.13.1 https://dl.sammobile.com/Odin3-v3.13.1.zip
-You can install the Samsung driver using SmartSwitch if your Win PC can't detect your Samsung phone (it should show on Device Manager > Modem > something like Samsung Modem)
-*READ* You can't flash back to version 6.0 now because of (Android Oreo 8.0 is using different version of boot-loader) but there are some late Android 7.0 with updated boot-loader, those are using boot-loader binary v2, so binary v1 it will be conflicted and won't work upon flash.
-*NOTE* Download the correct firmware of your phone model by following the baseband, that's why I recommended to take screenshots of your phone, you can search it on here https://www.sammobile.com/firmwares/, for mine, I've searched SM-G935F and BTU is my choice, the filtered results should be your correct firmware. But in my case I used (v7.0 in March 2018) because it has the binary boot-loader v2 with it (whatever it called, it's important otherwise it will not work which I've tried)
-*optional*, if you find sammobile download speed is way too slow* You can use https://updato.com/firmware-archive-select-model?q=SM-G935F&exact=1&r=&v=Nougat%28Android+7.0%29%2COreo%28Android+8.0.0%29&rpp=100, and basically look for the correct firmware which I have mentioned above.
-Extract your firmware onto a single folder, don't mess them up! (you should see something like AP_G935blahblahblah.md5, and you will need AP_, BL_, CP_, CSC_ for downgrading)
Follow the steps:
1. Now you have the correct firmware and Odin running on Admin right
2. On Odin you can add AP_, BL_, CP_ & CSC_ onto the correct selection, for example: https://i.imgur.com/DIB2d1S.png
3. Have your phone on Download mode, google it if you don't know how (make sure you followed the On the phone step first, it's very important)
4. Find a data USB cable and plug into USB2.0 port, make sure your phone appeared on Odin (you will see something like 0:[COM5])
5. On Odin (only Auto Reboot, F. Reset Time) is needed, it should be ticked by default.
6. Now you can safely click 'Start' on Odin.
7. DO NOT TOUCH YOUR PHONE in case your USB is loose which I had experience before.
8. Wait until it shows a green PASS! like this: https://i.imgur.com/FYosmx2.png
9. When see a blue screen with Erasing text on it, please wait until it reboot and hold (Volume UP + Home Button + Power Button) boot to recovery mode
10. Wipe cache partition, and data/factory reset then reboot system now
11. Wait for it to boot into your sweet sweet Android Nougat 7.0 (Late version)
12. Disable auto-update if you wish, mine was on auto-update so I had to pause it half-way
Hope you find this guide helpful, I tried to remember the steps on my head as I typed, (*sorry for the grammar if you find it hard to understand) and if you think I've missed something here, let me know! I would update the guide if any step is missing, just in case
Thanks
I'm guessing Knox counter wouldn't have incremented?

Hello dear!

Help with G930A
Hello um I have a Samsung Galaxy S7 on AT&T (G939A) and it's on 8.0 (G930AUCS9CSB1). I've tried to root it but after some research I've come to find out I have to downgrade it to nougat to root it. But the problem is everytime I load a firmware it fails and I did more research I think it said something about the bootloader blocking it and the only way to downgrade the bootloader is downgrading the firmware which I can't do because of that cycle. Can someone please help me all I want to do is root install a custom recovery and a custom rom I love playing around with android tweaks but I can't get it because of this. I hope someone can help me please and thank you.

Your bootloader cannot be unlocked due to it being Snapdragon, so unfortunately there is nothing you can do. Only Exynos variants can be modified.
Hello guys,I have a problem with my galaxy s7 sm-g935f(Exynos version).Few months ago I flashed my phone from android Nougat SEE CSC(South East Europe) to UK's Oreo BTU CSC.I'm curious is there any other way to downgrade it from oreo to nougat,otherwise than Odin.I tried flashing it a few times with the latest Odin version (3.13.3) and nougat SEE CSC(South East Europe) because that's my original CSC.Odin recognizes the device normally,but when i click start,it comes to setup connection and then FAIL.The reason I'm trying to downgrade is very poor battery life and heating,and the phone is very laggy.I even tried through Samsung Smart Switch Emergency software recovery but it seems that Samsung has restricted that option...please help if anyone has/had similar problem.Thank you!
Mine is Sprint g935pvpsbcta1
Am I screwed also?
Hi, I have
SM-G935Fand I can't find any nougat firmware with baseband of: G935FXXS8ETCA.. Can I flash any country / baseband 7.0 firmware? And will it improve the SOT? I'm currently getting upto 5 hours SOT.

Sorry we still don't have OEM unlock or a Root method for this model . This was to get android 10 on our phones when our carrier's haven't released it yet using the Xfinity mobile's update .
Well thank you sir . My mom just bought this phone and she customized it. I said don't because figured it would erase . Well after your instructions on it she now has Android 10 and all her settings were still there ! I wish we could do something like that with the J7 perx which I'm using now the twrp went to 3.4 , getting other J7 roms. Well back to the A205U, I was little discouraged because you could enter MSL or a generic MSL number on android 8 and 9 and activate native tether. With 10 I couldn't, well it did though let me create my own apn and save it so native hotspot working still ! Thank you Peter !

Isn't TMB T-Mobile? So is TMK Metro? Want to flash the correct version for my phone too. We received a security patch mid June for Pie. Flashed the Xfinity Q thinking we wouldn't see Q for a few months.

Yes, CSC TMK is Metro. And you can flash all 5 firmware files this time to get your carrier branded implementations. As well as HOME_CSC if you don't want to lose current data.

I don't see where to put the home file. Only slots for AP, BL, CP, CSC, and USERDATA. Do I put HOME_CSC on CSC slot?
Edit: Nvm I got it thanks!

I'm want to go in the opposite direction. Want to downgrade to Adr. 9 (pie) for a couple of reasons. Anyways, it's been determined(?) the B/ler is locked (Galaxy SM-A205U). Do you have any methods, advice on how I may go about achieving a B/ler unlock and/or downgrade?

If the bootloader has been updated... it's a trap.
Pie is a better OS; supports trusted overlay apps, more functionality for 3rd party apps and no scope storage.
Unless you do something stupid security isn't an issue with Pie.

RE: blackhawk
Thanx for the info. Perhaps you can give me an answer to another question. One of the reasons I want to revert to pie is that I could get local (not i-net) FM radio. This phone has the chipset and I had local FM until the And. 10 "upgrade"(was it?). Right now, I'm hesitant to attempt the downgrade because all the talk of the B/ler being locked. Once I figure that out, then I'm sure I'll do the downgrade. I have an idea how to defeat the locked B/ler, but I need some more info before I try it. Stay Sharp!

Maybe a different stock rom Android 10 would support the FM radio? I never had that feature so I know nothing about it.
It's now completely missing? Maybe you need an app to access it that's missing rather than the firmware not supporting that hardware.
Look in Developer options and in Settings where it use to appear.
Try some Google searches.
Hello
I've been reading forums and downloading files for days. Many of the links in the posts no longer work. Posts are 5 years and older. There are no new ones. At least not one that actually works. Downgrade I mean. That's why I wrote this question and I'm asking for help - how to really downgrade my Galaxy S6 G920F.
Thanks for the help.
PSA: Downgrading WILL void your warranty!
What have you already done (what method, software) have you already tried?
The 100% surefire way to downgrade your phone (or any android phone really), is to:
1. Backup your phone data.
2. Switch the phone into download mode, connect to PC, boot into TWRP recovery through fastboot
3. Wipe your 7.0 firmware and all data
4. Flash android 5.02 ROM
For a samsung phones ODIN + Freya is also an option. Odin is a samsung's firmware flashing tool, Freya is a 3rd party program that can download the stock firmware android for you. All of these tools are available online, and you can ask on a samsung subsection of XDA about how to use them - people can give you up to date links.
I'm laughing because you write quite a lot in three days. Of course, this method does not work.
Is there anyone willing to help?

That is assuming they have TWRP.
Also, the part you mention about "boot into download mode, connect to PC then boot to TWRP via fastboot" is not correct because Samsung is not compatible with fastboot, adb works but fastboot does not. Some Samsung devices technically have a "fastboot mode" but it isn't functional, it doesn't respond to fastboot commands, it's basically useless.
Also, you can't flash a firmware that has a lower binary than the currently installed firmware so if the binary of the downgraded firmware is lower than the binary of the currently installed firmware, the downgraded firmware can't be flashed.
Samsung is making it harder and harder to downgrade their devices.
OK. I'm afraid I'm missing the point of what's being said.
I know it is possible and there are also posts about it, but they are old, the links in them do not work. I'm asking for an expert who knows how to do this, philosophizing about what it would be like if it somehow doesn't really help me and I'm not interested either
I'm only interested in a positive thought, help and not brainstorming, if you understand me?
No offense
