I have never used skipsoft but I know that you cannot downgrade the 4.3 bootloader.
Try this:
1) Download ODIN and extract the zip file from here.
2) Download this file and then extract it. The extracted file will have a tar.md5 extension.
3) Boot your phone in-to download mode by i) turn off phone ii) hold volume down + home then press power iii) on prompt press volume up.
4) Start Odin on your pc(windows) with admin rights, (right click and run as admin).
5) Now connect your phone to PC, on ODIN if you see a message that phone is connected.(ID:COM tab on left will turn blue)
6) Click PDA tab and browse the extracted file, it will take couple of minute to verify md5 and then once it's done
7) Auto reboot and F.Reset time options are checked by default, leave them as it is and make sure no other options are selected/checked on ODIN.
8) Click Start
8) Let ODIN do it's job, phone will reboot automatically.

[Q] Need help making sure

Hi, this is my first time rooting and installing a custom rom onto my phone and I just wanted make sure I didn't forget anything of do anything stupid...
Alright so I have a SG3, the Videotron Variant on 4.3 stock rom
I downloaded the drivers for my phone, am using the USB cable, and have installed Odin on my computer.
I followed this post : http://forum.xda-developers.com/show....php?t=1771687
and I downloaded the "Videotron image"
my following steps would be to
"Extract the root66 tar file from the .7z file you downloaded.
Put phone into download mode [ with phone off, hold vol. down + home + power ], connect to computer and open Odin.
once in odin click the PDA field and select the root66 tar you downloaded.
Leave Auto Reboot and F. Reset Time checked.
click start and
when done let phone reboot."
and third of all, i'd install ClockworkMod recovery then grab Rom Manager from the Play store and in the menu select to install ClockworkMod Recovery and then install a custom rom from there
Am I missing any steps? For example I was reading about the OTA update section and I didn't understand anything...
Thank you!

Do you remember what (stock) firmware or Android version you were on before the attempted installation? Your best option now would be a return to stock. If you were on anything earlier than 4.3 (e.g. 4.1.2 or 4.1.1) you could try using Odin to flash 4.1.1 since you can get into download mode. To do this take the following steps ..
1. Download the required files via the following link <http://fortedge.com/downgrade.html>and extract the Odin flashable file
2. Install Odin
3. Boot into download mode and flash via Odin
OR you could find the correct stock image via the following discussion thread and flash via Odin. This would be a complete stock file that will flash all partitions including bootloader, modem, kernel and system.
http://forum.xda-developers.com/showthread.php?t=1739426
If you were on Android 4.3, then you cannot use the above method or flash via Odin and any attempt to do this will create more bother for you. In this case, you would need to flash custom recovery via Odin and restore the stock recovery image via custom recovery. Please download the stock recovery file via the following the thread ...
http://forum.xda-developers.com/show....php?t=2658486
If you need any further detailed steps on how to complete this, please do not hesitate to holler.

Download Odin.
http://fortedge.com/downloads/Odin307.zip
Download the Odin flashable custom recovery file via the following link ...
<http://techerrata.com/browse/twrp2/d2att>. You need one of the more recent images ending in *.tar e.g. the one below
<http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.0-d2att.tar>
Install Samsung Kies on your PC if you don't have this already (this will be useful for the drivers)
Install the twrp tar file to an easily remembered location on your PC
Extract the Odin zip to get the executable file (*.exe)
Click on the exe file to run Odin
Now boot your phone into download mode by powering off completely then holding down the Power + Home + Volume Down buttons simultaneously until you see a warning message.
Press the Volume Up button to continue
Connect your phone to the computer with a good quality micro-USB cable
If everything has been done OK, Odin should immediately recognize your phone and you should see a message saying "Added" in Odin. If you don't see this, then you may need to check the drivers are properly installed.
Click on the PDA tab in Odin and navigate to the twrp tar file you earlier downloaded. Select this file and click OK.
You should have the Auto-Reboot and F-Reset Time boxes checked in Odin. Please do not check or uncheck any other boxes!
Click on the Start button at the bottom to start flashing TWRP and wait until you see PASS and a green (or blue) box fully displayed. Your phone will automatically reboot after this although it may not be able to boot since you don't have an OS installed. You may disconnect the cable and close Odin after you see the PASS message. If you see FAIL, then disconnect, remove the phone battery and try again.
If you successfully flash TWRP, then you may proceed to reinstalling your ROM.
1. Download the zip file in the thread below <<http://forum.xda-developers.com/showthread.php?t=2658486>>
2. Save to a recognizable location on your phone's SD card. If you can't install files to your phone via your PC, then you may save to a micro SDHC card using another micro-SDHC compatible device (camera, another phone, card reader/writer etc).
3. Boot into recovery mode
4. Select Install from the TWRP menu and navigate to the zip file you download. Swipe the arrow key to confirm installation and wait for installation to be complete
5. When installation is complete, clear your cache and dalvik and reboot system and you are good to go.
Hope this works for you. If it does, please remember to hit the thanks button and let me know.

You may also try Odin 3 v1.85 if the v 3.07 didn't work. I've been looking for a safe download link for that online but I've not been able to find one. You may try searching for it online.

Here is Odin 1.85
Or you could try putting a room on an SD card. That's why I always check to see if a room is there before flashing

Reinstalling OS after accidental delete

While attempting to install 6.0.1 on my SM-T705 I accidentally deleted the OS leaving me with the black screen of death (Samsung Tablet S logo and powered by Android). As I have only recently moved to Android and am still learning the ropes so any idiot-proof instructions to resurrect my tablet would be appreciated.
Thanks.
Glenn
Just flash the stock firmware with odin. Available at sammobile or youmobile.
Next time don't be silly and use TWRP to make that all important backup.
Here is how to flash firmware on your device:
1) Obtain the firmware. I find the most trustworthy place to DL it to be SamMobile. (You will need an account and it is a very slow download)
2) Download Odin3. It can be downloaded from here.
3) Download SAMSUNG_USB_Driver_for_Mobile_Phones.zip from here
4) Extract the zip and install the drivers
5) Power off your device. Once it is fully powered off, hold POWER+VOLUME DOWN+HOME until you reach the "Custom OS" screen. Once you reach this screen, press Volume Up.
6) Plug your device into your computer and extract the Odin zip. Now run the Odin EXE.
FOLLOW THE INSTRUCTIONS FROM THIS POINT ON VERY CAREFULLY
8) Extract the .tar.md5 from the firmware zip you downloaded from SamMobile earlier.
7) In Odin, select "AP" and select the .tar.md5. Odin will appear to hang, but give it a few minutes to finish processing the file.
8) Click "Start" in Odin.
9) Once the firmware download is complete, your device will reboot. It should work after this. If not, reboot back into Recovery mode to factory reset.
Thanks to you both for the help. I'm back up and running and the tablet has already been backed up with TWRP just in case I do something dumb like this again.

Samsung Galaxy Tab S 10.5 (can't get out of retail demo mode)

I purchased a used Samsung Galaxy Tab S 10.5 on ebay. Originally it had Android 4.4.2
When I turned it on the device is in retail demo mode.
I have tried the following
1) passwords found on this forum such as (5444, M729Q16K8546, blue, unlimited, easy, galaxy)
2) none of these worked
3) Can not deselect "samsung retail mode" in settings/security/administrators
I tried updating to android 6.0.1 by doing the following but the retail mode is still there
It will not enter into download mode so I did the following
1) Enabled developer options on tablet
2) Used command "adb reboot download"
3) Installed Android 6.0.1 stock rom (T800XXU1CPH7_T800XAR1CPH4_XAR.zip) from sammobile.com
4) Tablet installed and updated Android
5) Retail mode is still there and I still can not get rid of it
Any suggestions are greatly appreciated
Thanks
Never had a retail demo device so my answer may be limited.
Did you tried/are able to install TWRP ?
If you can get TWRP you can try to make a complete factory wipe (Advanced Wipe > check all the boxes > wipe)
Then reboot to download mode (Reboot > Download)
Install the stock rom again
Here is the link: https://forum.xda-developers.com/ga...p-2-8-6-1-unofficial-sm-t800-805-807-t3074633
Flash it via odin
I have tried to do TWRP but can not get it to work. I did not use the apk I was using ODIN on my pc. I was using a TWRP file twrp_3.0.0-0_T800. Not sure if that was the issue or not.
Here are the steps I used:
1) put phone into download mode by using adb on pc (adb reboot download)
2) In ODIN
a) turn off autop reboot
b) select AP file twrp_3.0.0-0_T800
c) wait for success in ODIN
3) tablet never rebooted so I used these keys (press at same time until reboot power+vol down+vol up+home)
4) Tablet rebooted into normal running mode
If you don't enter in recovery right away you flash it the system will revert the changes back. so if the system start to boot normally you need to flash via odin again.
I recommend you to flash the version i linked, as it is more compatible with MM bootloader, also turning off auto reboot is a very important thing.
You need to press all the buttons together power+vol down+vol up+home, (press power last) . when the screen light up release the volume up button (the next to power button) and keep holding the rest.
also...
You can try one trick that i use sometimes, it will give you more time to make the key combination, connect the device to the charger and press and hold power+vol up until the screen turn off, it may show a battery icon, so you disconnect the charger and wait the icon go away. the device should be turned off now. so you basically press and hold vol down+home+power (press power last)
If you done the combination correctly and the screen became black, don't worry, it is a bug, just wait some time (1 min i think) and press home key, it should show the recovery.
It can be a pain in the a** sometimes... but trust me, it generally works.
Ok, so far so good. It took a while but I got into TWRP. But I can't seem to select the image file.
I have it on an external MicroSD in the root. File is called T800XXU1CPH7_T800XAR1CPH4_XAR.zip
I can browse files on the list on the left. But I can't seem to find the file
Did I miss a step?
Somehow after going through menus, it recognized the file
But when I tried to install it, I got these errors
Zip Signature verification failed!
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
Could not find 'META-INF/com/google/android/update-binary' in zip file
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
you got me wrong, in the TWRP what you need to do is make a complete wipe (Wipe > Advanced Wipe > check all the boxes > wipe)
then you need to enter in download mode. (Reboot > Download)
and flash the rom via odin!
extract the zip on your pc, it should be a .Tar file, select AP mode on odin, select the .tar and flash it in there.
I apologize for the confusion. Those steps worked!!
I think part of the problem is that I did not extract the firmware file. I kept trying to flash the TAR file.
I did a wipe in TWRP
Then rebooted into download mode
Flashed extracted firmware file in ODIN in AP Box
Then the tablet rebooted and was in setup mode like a brand new tablet!! Who hoo.
Works great
Thanks for all the help

Android 9.0
Hello, when it will be possible ? If never, why ?
I followed the exact process but everytime i tried to boot into TWRP recovery immediately after the flashing, the device still boots into stock recovery instead of TWRP
Please help me with this
Thank you
I figured out a way to root the Galaxy J7 duo
Actually i have tried lot of ways to root using TWRP flash and all.. but one day i accidentally bricked my device
So i downloaded the stock ROM to flash my device
And i downloaded the 8.0 android ROM
So this root method basically tested on android 8.0
So now i have android 8.0 stock ROM downloaded
Step 1 -
So make sure you also downloaded the ROM
And extract the ROM file (you must have got the "AP" "CP" "BL" "CSC" and "HOME CSC" file)
Then copy the "AP" file in your phone
Then install magisk manager in your phone
Open magisk, select install, select and patch a file from magisk
Then select "AP" file
And wait while magisk is patching the "AP" file
When flashing is done the patched file will be saved on storage, emulated, 0, download (file will be saved as "magisk_patched.tar")
Then simply copy the patched file in your computer
Step 2 -
Open odin in your Computer
In odin, select "magisk_patched.tar" in "AP" section
Select "BL" from the stock ROM folder in the odin's "BL" section
Select "CP" from the stock ROM folder in the odin's "CP" section
Select "HOME CSC" from the stock ROM folder in the odin's "HOME CSC" section
make sure you select all the official files from the stock ROM folder... just instead of the "AP" file, select the "magisk_patched.tar"
Then connect your phone via USB cable
Odin will detect and show "added" message
Start the flashing process
It will take few minutes
When its done your phone will boot up
But it will show something like "erasing" and "verification unsuccessful"
Just agree with that and erase the phone
(It will cause a data loss because everything will be deleted and your phone will reset, so i suggest to make a backup using samsung smart switch)
Then when your phone will reboot, just follow the steps to setup
Amd install magisk latest apk
Open magisk and boom!
You can already realize that magisk root is activated
Amd magisk will ask you to "setup environment"
Just agree and your phone will reboot withing 5 seconds
And done!
Your phone is now rooted
Install root checker and verify your root status
how to un-brick
Same thing here,
Tell me how you un-bricked your phone
I bricked my phone by installing wrong twrp file to sm-j720f android pie with odin
and now it shows only bootloader screen and I can't even go to recovery mode or home screen just showing " SAMSUNG GALAXY J7 DUO secured by Knox powerd by android" noting else
That is exactly what was happened in my phone
So what i did just downloaded the Stock ROM for J7 duo from the sam mobile website.
Then extract the ROM and you will get few files ("AP", "BL", "CP", "CSC", "HOME CSC")
Then boot your phone into download mode using this method
(Connect the phone to your PC using USB cable, then press and hold Power + volume down + home, then when the "powered by android" logo appears release only the power button... so your phone will boot into download mode, press volume up to continue)
Now, in odin you can see "added" message that means device is connected
Now select the ROM files respectively, BL, AP, CP, CSC
Then click start, and the process will start, will take few minutes
When done, your phone will boot normally
Yeah everything is right until...
[grand_theft;83142325]That is exactly what was happened in my phone

So what i did just downloaded the Stock ROM for J7 duo from the sam mobile website.

Then boot your phone into download mode using this method
Fact that I cant even go to download mode I tried out many times
Just follow this step
(Connect your computer with your phone using USB cable, then press and hold Power + volume down + home, then when the phone vibrates and appears the samsung logo again just release only the power key, while holding the volume down and home key)
(Just release only the power key when the "powered by android" logo appears)
Thats how you can go to the download mode
No virtual change
Done it as u say,
But my mobile shows noting but just logo screen
*****SAMSUNG GALAXY J7 DUO secured by Knox powered by android*****
again and again
These is not first time, last I did the same mistake before and I went to Samsung service store they recovered it, I don't know how they did but it worked.
These time I want to (tring to) do it on my own bcoz I love playing with ROM's, root, etc.
Thanks for replys
I also did the same mistake by flashing wrong TWRP
But however i managed to enter into downlod mode following those steps
And flashed official ROM to unbrick the phone
You must go into download mode to flash the official ROM using odin
Thanks alot
Thanks man,
I'm able to enter download mode and I installed official ROM. Now in using it as normal but (1)Secure folder and Pay mini are not working.
(2)Do you have any idea on other ROMs that works on SM-J720F other than Samsung's one UI.
(3)can I install android 8 on it in ordered to root as you said it in previous post.
(4)from previous your post on oreo twrp explanation, is twrp works fine. What happens to twrp if I update phone to Q (from system updater)
I'm glad you made it!
Now,
1) Secure folder and pay mini won't work because the phone thinks you rooted your phone and maybe your binary is cracked (so forget using those)
2) I'm not sure about any ROMs which is stable with this model. But you can search the internet (I think pixel ROM is pretty popular)
3) I'm not sure if my process of rooting supports android 9.0 or not, because i personally tetsted it on 8.0, So you can download the oreo ROM from the internet and then follow all the steps i mentioned before
4) If you want to install TWRP, you can still install TWRP after rooting via the method i provided
(You can install TWRP using flashify on a rooted phone)
But if you want root access then you can simply root your phone first..
And whatever custom ROMs you want to install, install it using flashify
Because if you update software via official OTA, the root access and TWRP both will be gone
And if you root your phone, then however you won't be able to perform a official OTA update.
(First root your phone, then simply download your TWRP file and flash it with root permission within your phone)
Instated of Oreo AP file,

So this root method basically tested on android 8.0
So now i have android 8.0 stock ROM downloaded
Step 1 -
So make sure you also downloaded the ROM
And extract the ROM file (you must have got the "AP" "CP" "BL" "CSC" and "HOME CSC" file)
Then copy the "AP" file in your phone
Then install magisk manager in your phone
Open magisk, select install, select and patch a file from magisk
Then select "AP" file
And wait while magisk is patching the "AP" file
When flashing is done the patched file will be saved on storage, emulated, 0, download (file will be saved as "magisk_patched.tar")
Then simply copy the patched file in your computer
Step 2 -
Open odin in your Computer
In odin, select "magisk_patched.tar" in "AP" section
Select "BL" from the stock ROM folder in the odin's "BL" section
Select "CP" from the stock ROM folder in the odin's "CP" section
Select "HOME CSC" from the stock ROM folder in the odin's "HOME CSC" section
make sure you select all the official files from the stock ROM folder... just instead of the "AP" file, select the "magisk_patched.tar"
Then connect your phone via USB cable
Odin will detect and show "added" message
Start the flashing process
It will take few minutes
When its done your phone will boot up
But it will show something like "erasing" and "verification unsuccessful"
Just agree with that and erase the phone
(It will cause a data loss because everything will be deleted and your phone will reset, so i suggest to make a backup using samsung smart switch)
Then when your phone will reboot, just follow the steps to setup
Amd install magisk latest apk
Open magisk and boom!
You can already realize that magisk root is activated
Amd magisk will ask you to "setup environment"
Just agree and your phone will reboot withing 5 seconds
And done!
Your phone is now rooted
Install root checker and verify your root status

Ok I agree with you,
But what if I replace Oreo's AP file with android 10's AP file(which I installed recently on my phone), will it boot with root or not.

I have not tested this method on any other android version, you can still try it on your own, there is nothing to lose, just make a backup before flashing. If you succeed then that's great
But i have personally tested this method only on android 8.0
(Before doing anything, just make a proper backup using samsung smart switch. So you can restore your important data)
Success
Replaced with android 10's AP file and flashed with Odin. Now my phone has rooted with Magisk manager.
Any suggestions to tweak android

Have you ever got the answer or figured it out? I've got the same model and I cannot find anything on the net to help me with rooting this phone.
