So you have decided, or maybe trying to decide, to invest a good chunk of money into a Developer Edition S5 instead of a retail version. Here are a few tips and general information that you need to know before you start to "tinker" with the Developer Edition S5:
1) The Developer Edition S5 can only be obtained from the Samsung online store (site). When you receive the S5 you should understand that it is going to look, feel and perform exactly like the retail version of the S5. The only way you can tell the difference is to pull the battery and look for the words "Developer Device" printed on the S5's board under the battery. You will have all the bloat etc that a retail version has. The only difference is that your bootloader, unlike the retail version, is unlocked. The phone will come with the latest version of Android that Samsung currently supports...the same version as the retail S5.
2) After your initial boot, and before you do anything else, go to settings>security and disable (uncheck) the Reactivation Lock. If you don't do that before "tinkering" with your phone you stand a very good chance of successfully bricking your phone while flashing a recovery or rooting your phone. Next go to About Phone>Build Number and tap it about 6-7 times and enable Developer Option and then enable USB Debugging.
3)A word of advice: Never, never take an OTA update. If you do, you stand a real good chance of locking your bootloader. Samsung has never released a OTA update specifically for their Developer Edition phones. Allowing a retail OTA update to download and install on you Developer Edition will most likely lock your bootloader for good. Sending it back to Samsung will not help you. They will not unlock your phone, and you cannot unlock your phone. You are stuck with a very expensive retail version of the S5. Keeping the Developer Edition up to date is not a problem. Our developer community does a great job taking the latest updates and creating ROMs that are safe to flash on our devices. It may take them a day or two, but it happens.
4) Installing a custom recovery...the first step: First, download and install the latest Samsung drivers on you PC. Then download and install on your PC the latest version of ODIN. Version 3.07 also works if that is what you already have. I recommend TWRP as the best custom recovery to use. Download the latest version of TWRP and place it on you PC. Start ODIN. Power off your phone and then holding down the volume down - button and the power button boot into Download Mode. Once in Download Mode connect your phone to your PC using the supplied USB/charging cable. Wait for ODIN to recognize your phone (phone info will appear in the ID:COM window in ODIN). In the Message window in ODIN find the TWRP .tar you downloaded and highlight it with your cursor. Select the PDA block in ODIN. Now select start. Allow ODIN to do its thing. Do not disconnect your phone until you get the Green Pass notification in ODIN. Disconnect your phone and reboot. You now have a custom recovery installed. NOW DO A BACKUP using your TWRP recovery. Do it right now!!
5)Rooting: After installing a custom recovery (TWRP), download the latest version of SuperSU and place it in your internal storage or external sdcard. Boot your phone into Recovery, wipe cache and delvek, you can also do a Factory Reset if you choose, then select install, find the SuperSU .zip, and flash it. Reboot. Now you are rooted. You can confirm (recommended) that you are rooted by installing Root Checker from the Play Store and running it.
6). OK, you have a custom recovery and rooted. You can now take advantage of the benefits of an unlocked bootloader. There are a number of good ROMs you can flash in the Android Development Section. Caution...Do not flash a ROM that says "Retail". Most developers will say whether it is safe for Developer Phones. There are also some AOSP ROMs that are "Works In Progress" in the Unified Section. You can flash those, but they are not quite ready for prime time yet.
7) Just a reminder: Do not take an OTA. Do not flash Retail Firmware.
Thanks!
Been reading and reading, and reading some more to learn all I can about my Developer Edition. Appreciate this post, and the concise information. :good:

I had S5 dev edish for 2+ years with TWRP + rooted 4.4.2, and life was great. Then when I went to sell it I thought I would update it first to 6.0.1.
1.) Was that a horrible mistake??
2.) If I locked the bootloader by flashing stock 6.0.1, how can I confirm this?
3.) Is my only option to have Samsung revert/unlock the phone to 4.4.2? Or can I root 6.0.1?
4.) If you were selling it on ebay, I assume it's more valuable as 4.4.2 root/unlock than dumb retail 6.0.1?
P.S. I've spent over an hour trying to find these answers myself.
If you have a dev ed then it shouldn't lock the bootloader even if you go to MM.
It's not really worth more one way or the other unless someone is looking for a device already rooted, ready to go.
To check if locked:
Power off
Hold home button, down volume button, and power together
At warning screen, press up volume button
On "Downloading" screen - look to see if it says "Mode: Developer"
(If it does, you're unlocked)
If you're locked, I believe you can just go back to Lollipop, root, and unlock again using this thread:

Hello,
Noob Q here. What is the best/safest root method and install custom recovery(TWRP) for my G920F from Philippines thats still running 6.0.1 ,CSC-xte ,network SUN but already openline both sim slot. And which rom you guys recommend installing that would work for dual sim S6. Because it seems Samsung has abandon the update to android N for this specific variant or CSC. . By the way , ones the phone is rooted , can i just flash any Nougat ROMs for G920F even if coming from MM ? Thanks in advance and any information is highly appreciated.
I think you want to upgrade device to N, that's why you want to root, right?
If so, just upgrade it via Odin without tripping Knox and wiping your data.
Every SM-G920F ROM has compatibility with dual SIM model.

Yes ,you are right on the dot. Just want to upgrade to N. But i have no idea which firmware to use that would work properly for my S6 . And from my experience with older Samsung devices , they seem to work way better if i do use custom samsung base ROM. So im at the part were im still contemplating if i should root and use custom rom or upgrade it with stock N firmware using ODIN that might work well with my S6 ,cause i know there is
no N firmware yet for my CSC (XTE). At the moment , i do not have any other back up phone that i can use in case my S6 goes soft brick. Thank you so much for the suggestion , and your actually the second person that said to just upgrade it through ODIN , so i might just do that. Just need to find out which one to use exactly.

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.

I just wonder this solution will be work as well? my phone is s6 edge plus G928C.
And i want to downgrade to 5.1.1 or 6.0 because 7.0 was really terrible.
Hello there
I bought a Samsung J7 Neo (SM -J701M) on another country than mine (Im from Argentina, device bought on Paraguay). Anyway, I started to look another way to get some space on the internal storage and I remember that android had an option to expand it, using a SD Card. Unfortunately, i realize this option is not allowed on samsungs device, but it works (i read it, because can't do it) if you get root user.
So I looked how to do it and i found a group of files
ODIN v3.12
Magisk v.14.5
twrp v.3.1.1 -j7 neo
Im not sure if I downloaded the right files, but im start the process anyway.
I followed point by point
First I installed TWRP Recovery v3.1.1 (which is supposed to be correct to my model) and then already on twrp rom I installed magisk 14.5 from sd card and did wipe data.
Turned on the phone and I restored all apps from a google backups, and I realized I cant find app "Magisk" on the device, so I decided to reboot the phone and it starts to do a bootloop with this error "kernel rev. check fail, device:2 binary:1"
At this point, I failed every attempt to fix this error
I tried installing the last official firmware that i found (and Im not sure if its the correct one)
J701MUBU3ARC2_J701MUWT3ARC1_UFN
And I got this error
"SW REV. CHECK Fail (BOOTLOADER) Device :5 Binary 3:
I searched on google this kind of error, and I found that I have to downgrade the bootloader. And this is why im here beacause I dont know how to do this, and if its works, i don´t know how to continue the process to root and expand my internal storage. So I really appreciate if someone one could help me with this. I can learn fast and I love to do this things by myself.
Thanks for your time!

If you have to downgrade the boot loader, it means the firmware you are flashing is older than the one on your fon.
Go to www.updato.com and look for the he latest J701M firmware.
You can sort the list by date and by region.
And the site is download manager friendly ?
Good luck!
Sent from my SM-J700F using Tapatalk
Thanks for your answer! One more question about the region. Should I download firmware from the country that I bought the phone or firmware from the country that I am?
Look for your country specific firmware first.
Otherwise Samsung usually has regional software - i.e for several countries in a region e.g. Argentina, Paraguay.

Hi There,
Did you have any luck with your Phone? I have the same exact model but I have Android Version 8.1.0, Samsung Experience version 9.5; Android security patch level -Feb 1, 2019; Baseband version: J701MUBS6BSB3 and like you, I love doing things myself, and I can't seem to abide a smartphone that's not rooted.
I'm not exactly a newbie, I've been assisting devs with testing and such on AT&T SGS3 for quite some time. But I can't seem to find a stable method for rooting for this phone, no one seems to be doing any development on it.
I would love to hear your story thus far.
im needing help myself, i have the SM-J701M (J7 NEO), with android pie 9 official, but the binary is 7 (because Argentina Geniuses of course) and of all the things i tried nothing works, and the only thing they did was brick the phone, so i flash and stock firmnware to be usable again

What have you done? I saw your messages on TG but everyone ignores usually, I had another problem and footbed the solution myself as I got ignored for days.
So, what have you done? Maybe we can figure it out a way to root it, but to avoid telling you things that you may have already done it is better if you let us know your already followed steps.

i tried flashing TWRP like a guide said (Latest version) but then got stuck with a boot loop in the Samsung Galaxy Logo, then when i enter to flash the latest global firmware it didn't work because it was binary 6, so i searched for the version in Argentina that has binary 7, after that i didn't try anything else in fears of getting fully bricked, i was thinking of the magisk canary way of rooting (patching the AP) but i don't know what happen if it fails the flash
Hi, i have the same device, SM-J701M, but when i try to flash the stock, it says that the device binary is 9 and the rom is 8, but i cant find the binary 9 rom in any place, only 8. I have the trwp installed, so I was thinking if I format all data (system and files) and try to flash again, it will work ?
Also im from Brazil (SM-J701MT), and the device was buyed in Paraguay (SM-J701M) too. Should i install the SM-J701MT ROM right ?
Some success.

Ok, guys, I've had a bit of progress with my device Samsung Galaxy J 7 Neo (SM-J701M- Android version 8.01)
On this phone, the option to unlock the bootloader was missing in Dev Opt and I knew that in order to achieve anything I was going to have to unlock the bootloader.
I searched and found that, via adb/fastboot (Google's Platform Tools) rebooting the phone to the bootloader you could enter the code: 'fastboot oem unlock' or 'fastboot flashing unlock' and voila! everything would be fixed...But...my device wasn't even being recognized by "fastboot" ! adb yes but no fastboot! Always the message: "Waiting on any device". Trying to find and install the drivers to do this was next to impossible.
It actually caused me soft brick my device. However, it was a blessing in disguise; I knew what had to be done, I was going to have to reinstall the firmware via Odin. I searched the site (Sammobile - you'll have to create an account.) and found the Oreo and the Pie Firmware, I downloaded both but played it safe and restored my device with the Oreo first.
And lo and behold the option to unlock bootloader was there! No hesitation, clicked that sucker fast!!
Now, I'm running PIE (No one has done a Custom ROM for this baby just yet) and with the unofficial TWRP in the first link below, it's a bit buggy but until they make an official one for us ... I guess we'll have to wait.
Oh! And don't forget to make a backup with Smart Switch!
And pay attention to the advice here:
Code:
1. Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
2. Add each file to its respective field in Odin v3.14.4. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
3. Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY
Other options in case first option did not work or isn't possible.
Option 2 VOLUME DOWN + VOLUME UP then USB cable
Option 3 POWER + VOLUME DOWN + VOLUME UP
Option 4 POWER + VOLUME DOWN + HOME BUTTON
Option 5 (Note9) USB cable + VOLUME DOWN + BIXBY
Option 6 (Note10) POWER + VOLUME UP
4. Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
5. Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC

Hi, i have the same device, SM-J701M, but when i try to flash the stock, it says that the device binary is 9 and the rom is 8, but i cant find the binary 9 rom in any place, only 8. I have the trwp installed, so I was thinking if I format all data (system and files) and try to flash again, it will work ?
Also im from Brazil (SM-J701MT), and the device was buyed in Paraguay (SM-J701M) too. Should i install the SM-J701MT ROM right ?

I think that's because you have to be specific with the carrier; Orange; Nextel; Movistar...that makes a lot of difference in with the firmware. If you can, check to see what you had before and try that first.

Ok, guys, I've had a bit of progress with my device Samsung Galaxy J 7 Neo (SM-J701M- Android version 8.01)
On this phone, the option to unlock the bootloader was missing in Dev Opt and I knew that in order to achieve anything I was going to have to unlock the bootloader.
I searched and found that, via adb/fastboot (Google's Platform Tools) rebooting the phone to the bootloader you could enter the code: 'fastboot oem unlock' or 'fastboot flashing unlock' and voila! everything would be fixed...But...my device wasn't even being recognized by "fastboot" ! adb yes but no fastboot! Always the message: "Waiting on any device". Trying to find and install the drivers to do this was next to impossible.

Hey, I noticed we have the same android version and and phone model, I wanted to know which version of Twrp you used . I am guessing version 3.1.1?
It's an Un-official version of TWRP, so the version #( 3.2.1-0) may not count, you can check the links out to get more information.
hola tengo un problema, tengo un sm-j701m binario 11 android 9 y quiero intalarle un twrp pero no se cual descargar y que funcione
Don't know if anyone's still following this thread or even still has this phone but there's been quite some progress with this device. (i.e: SM-J701M) The posts below will certainly help to bring your device up to date re: rooting; flashing etc.

https://forum.xda-developers.com/t/...laxy-j7-nxt-neo-core-j701-02-02-2021.4227921/
These posts contain links to ROMS and recoveries which have been sucessful, I can personally attest to this, my device was rooted and a custom ROM installed. I hope you will find them helpful.
Good Luck
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
