Having problem when downgrade from Nougat to Marshmallow SM-J510GN - Samsung Galaxy J5 Questions & Answers

Hi,
After receives OTA Nougat for my device i feel its very laggy and slow. Then i try to downgrade it to Marshmallow by using Odin.
First i enable the OEM unlock and usb debugging. Then download the latest Marshmallow firmware [latest november] that match my model.
Odin detected it and no problem when flashing. The phone then rebooted.
After the Samsung logo appear, the screen ask for password pattern and has the same wallpaper lock screen that i have for Nougat.
I unlock the password pattern then many popup windows saying bla bla .exe has stop working. Screen suddenly on and off and i cannot access anything.
I then try flashing another Marshmallow firmware [october update] but the problem still same.
Lastly i flashing back the Nougat firmware and its working back as normal but the performance are really bad and very slow.
May i know why i cannot downgrade to Marshmallow?

Right now im using this Nougat
Version Android 7.1.1
Security Patch Level 2017-08-01
Product code XME
PDA J510GNDXU2BQK1
CSC J510GNOLB2BQK1
Binary: Samsung official
FRP lock : off

I already find my solution.
"You will now need to go into Recovery Mode to wipe the cache. Regardless of what the phone is now doing, likely a boot loop. Press and hold VOL UP+HOME+POWER to boot into Recovery Mode. You will have a back screen with a text menu. Navigate with vol keys and select with power button. Choose WIPE/FACTORY RESET. Followed by WIPE CACHE. Then choose the reboot phone option."
This above step i miss. Now i already have my Marshmallow back.

Nougat is still not available for your country..So you have flashed latest stock 6.0.1 firmware using odin? Still you are not getting network signal? After flashing stock firmware don't restore your efs, it will be restored automatically after flashing...Now just again flash the stock 6.0.1 available on sammobile and after flashing when you see Samsung logo, simply press volume down+power button now your screen will turn off..immediately Press volume up+power+home button simultaneously untill you see Samsung galaxy logo, now release keys and you will boot into stock recovery..From there choose wipe data/factory reset option..After reset, reboot your phone..And see if singal back again or not?

Hi,
I realy need your help,
I have a S7 edge who is stuck at the samsung logo.
I have flashed some stock rom (all in 7.0) via odin 3.12 after a wipe factory but nothing. So i decided to try it with Kies and smartSwitch but still nothing.
I have access to recovery and download mode.
FRP lock: On
The phone is not rooted, and the usb debugging not enabled.
The phone print this in the download mode:
ODIN MODE
Download speed: FAST
Product-Name: SM-G935F
Current Binary: Samsung Official
System Status: Custom
FRP lock: ON
Secure Downlaod: Enabled
Warranty Void: 0(0x000)
RP SWREV: B:1 K:0 S:0
After the installation of the flashed rom in the download mode, the phone reboot with a blue screen, a progress bar but it stop to 32%, and then it is printed "erasing.." and the phone reboot and is still stuck.
I have re-tryed with Kies, now the phone is with a green screen with 2 white Gears : "android is starting" but it is still stuck (i let him all the night but nothing)

You have to use smart switch emergency recovery function to restore your phone. It is a stand alone function within smart switch.
All you need is your phone model and serial number.
Apparently you missed a step when preparing your phone for flashing.
Or you can continue to use Odin which when you plug the USB in will show that a connection is made even though the phone says it's not in download mode.

If that did not work, it looks like the memory chip on the mother board is damaged. Take it in if it is still under warranty.

To do the S7 FRP OFF - Put phone in download mode
Once phone is in download mode.
Flash the files which i will provide.
You Only need to flash boot.tar via odin for respective models (example for s7 use G930 Qualcomm folder) for (s7 edge use G935 Qualcomm folder)
Once you flash the boot tar file. The phone will reboot and it will enable ADB. Run the Bat file which i will provide and it will remove the FRP lock
Once done put the phone in Downlaod mode and flash stock ROM.
The whole process takes less than 10 mins.
Same Idea for S7 Exynos phones... put phone in downlaod mode and then flash the file (G930F(ENGroot) for s7 models & (G935F_Root for s7 edge models). Once done phone will reboot. Then use this bat file (g935f.bat). Once this is executed locks will be removed and phone will go in download mode. Flash stock Boot.img and ALL DONE.

After flashing boot.tar, when i run the .bat, it says error: closed
EDIT: i have to enter into the recovery mod and select "adb update" in order to make my phone detected by my computer
Those files are for the S7. Do they work for the S7 Edge also?
Edit - I tried it and it fails in odin. My phone is bricked.

Sorry to revive an old thread but I think it might help people recover from a bootloop with a bit of addtional explanation than initially provided.
So I have an S7 Edge as a backup phone and hadn't used it for a while. Google FRP was activated. I tried to update to a newer firmware through Odin (can't OTA since it's from Tmo and i'm in Canada). Anyways for whatever reason it failed in the middle and I was stuck in a bootloop that wouldn't stop. I tried downgrading, I tried factory, I tried new versions, nothing would do, I'm assuming because of FRP.
So I followed Rony Raj's post https://forum.xda-developers.com/showpost.php?p=71906126&postcount=17 but kept getting stuck. The thing is once you flash the proper Boot.tar file, the phone will appear to still be in a bootloop. You will have to go with the screen (the phone) and the sound of the connection and disconnection from your computer. So basically just sync with the sounds and time it so you open the ''S7 & S7 Edge QUALCOMM.bat'' file at the exact time your phone reconnects and it'll work. I had to do it about 6-7 times before i got it right.
When that is done your phone will restart in download mode. When you do just flash the latest version of the firmware you get from AndroidFileHos*.com or Sammobil*.com. Make sure you select all 4 files in Odin (BL, AP, CP and SELECT CSC HOME for CSC - NOT CSC).
Once all that is done your phone will restart and everything should be fine, well that worked for me
Thanks a lot to @rony raj for putting together the files and the steps to save my G935

unlock bootloader SM-G901F DTM

I am looking for a way to unlock the bootloader on my Samsung Galaxy S5 Plus (Sm-g901f, kccat6) with German t-Mobile branding (DTM) in order to flash Lineageos on it.
Is there a known way (executable for a newbie in Android flashing)?
Unfortunately my handset does not have a "OEM unlock" button in the developer options.
Is it possible to verify if the bootloader is locked apart from flashing a custom recovery and checking if it has been installed persistently?
i think you just have to flash twrp. if i remmeber correctly i had the same message that my bootloader was locked with my s4 i9506 back then

Even though my answer was posted a month ago, I want to present my solution:
As I said above, flashing TWRP did not worked on the way that all installation guides told me. But not because my bootloader was locked, the reason seems to be a bug (or is it a feature ) in TWRP.
The problem was, that the Stock OS is overwriting the bootloader on the first normal start.
What you have to do in order to prevent this mechanism:
1. Uncheck Auto-Reboot in Odin.
2. After Odin shows "PASS" shut your phone down and reboot it manually to the recovery.
3. In TWRP select Reboot and then System.
4. Done.
Now I am a lucky user of a LineageOS powered phone.
ooo yes thats a common odin bug for some phones..

When Odin passed !
Press download mode command keys
When screen goes black
Immediately press recovery commands !
And if u failed to reboot to recovery,flash firmware with nand erase all option !

1)To be say honestly downgrading is not officially supported by Samsung also But yes you can successfully downgrade to 6.0.1 from 7.0 (I personally downgraded to 6.0.1 once successfully due to issues on stock 7.0)
2)You only need to follow the guide as instructed carefully Also the version of 6.0.1 MM you will choose to downgrade to should be latest dated (I mean the latest 6.0.1 firmware for your device and country available on Sammobile.com casually)
3)Hence you can find some instructions within my own Post in which i mentioned step by step installations instructions (Go To Page No 65 And Find My Post In Reply To Okiera29 There Regarding Downgrading To MM From Nougat)

Ok thank you for your reply, I understand. I also had some trouble with drk verity fail issue when I factory reset because I run into issue with my efs, it was failing to boot ,but after searching the internet I found out how to fix the efs issue and then I flash stock over and then run into trouble with drk verity fail issue, but found a script to bypass this error ,but I read that whenever I flash or factory reset I will run into this drk verity fail issue again, so I must flash this script to bypass this error.
So my question after all i have explain is, will it be a problem to downgade to 6.0 because of those previous issues ?

1)Can't say exactly without trying or downgrading firmware as i said already neither samsung nor any community will officially support downgrading of firmware as it may cause various baseband and imei related issues due to downgrading of bootloader
2)But for safety you can take full Nandroid backup of your current stable rom using TWRP and Try to downgrade firmware at your own risk
Regards

What version of Smart Switch offers initialization for SM-N920C Note 5's? The latest version doesn't include initialization anymore at all, and an older version I tried stated that initialization was not supported for Note 5's.
All right, I'll see what i do.
Thank you very much.

smt-580 locked on chinese firmware (bootloader release 5)

Hello,
On my SM-T580 (TAB-A wifi) I flashed the last official rom with odin : PDA : T580ZCU5CSF1 / CSC : T580CHN5CSF1
2019-08-23 Release 8.1.0 T580ZCU5CSF1.
The flash went well but the tablet doesn't start anymore (black screen when switching on).
when I start in "download" mode, I get the download screen in chinese ...
However it is absolutely impossible for me to flash any other official ROM.
the flash starts and then goes to fail immediately with an error message in chinese "Bootloader locked".
the message on the tablet is: SW REV. Check fail ( bootloader) Device:5, Binary: 4.
I understand that the bootloader is now in release 5 and that all other ROMs are in 4 maximum. So it doesn't seem possible to downgrade my tablet and install an official (or unofficial) rom.
It seems to me that there is no solution as long as Samsung will not develop a functional ROM with a bootloader in release 5.
Do you have a solution for a possible downgrad or to make my tablet work ?
I also tried to flash a sm-t585 bootloader with a version 5 bootloader but without success.
Hi, did you found a solution? I did the same , and I have the same problem, the only difference is that I'm able to use my tablet, I flashed the last chinese firmware from march, its functional but with no google services.

The only way to bypass a locked bootloader/downgrade your bootloader is to buy a JTAG/Riff/Octoplus box and write the firmware you want to flash directly to the board.
Hi I have the same problem,
I was looking on Sam firmware for latest firmware and saw firmware for last month for my t580
Problem was it was Chinese, I thought just change the language during setup right? And then after I oem unlock and enable adb I can flash TWRP then root.
HOW WRONG WAS I?
The problem is the firmware for the t580 in China has bootloader locked.
Not only that, the bootloader has been updated to recent firmware and the btu (UK) and other firmwares only have a patch 6months prior.
So I am screwed unless the other countries update to a later security patch so I can pass the SW rev check and unlock bootloader again.
Just so noone else tries this as it's a PIA
#####EDIT ##### To solve this problem let the tablet boot up with the error code, connect to odin and flash the Chinese firmware again, then download and install crom service apk, goto developer options and do the usual, adb enable, oem unlock. Open the crom service app and select OK/Off whatever and reboot to download mode...
Once reboot to download mode and you will see crom service off and will be able to flash twrp, roms etc again.
