Sounds like the emmc memory is dead. Try to use these debrick images that I had taken from my i9195 some time ago. Extract first. https://drive.google.com/file/d/0B_vlSjY0nNrkX001ZUs4ZUF6dXc/view?usp=sharing

I had the same issue, 2days ago (also so an Galaxy S4 mini).
I solved it by holding the 'volume down + home button' while connecting/disconnecting the phone to my/from laptop.
I have the same problem
When i put the sdcard with debrick image in my phone, It says:
BOOT RECOVERY MODE
CHECK BOOT PARTITONS..
COPY FROM T-FLASH..
BOOT RECOVERY..
WRITE 139008 sectors..
FLASH WRITE FAILURE
ddi : mmc_read failed
ODIN MODE
PRODUCT NAME: GT-I9190
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Custom
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
BOOTLOADER RP SWREV: 2
WRITE PROTECTION: Enable
And when i connect it to pc to flash by odin, it says "There is no pit partition"
When i put the pit file in odin, it says the same
What should i do?
Did you get it to work? I have the exact same problem with the same phone (GT-I9190) !!!!
Hi guys,
hope you can help because I have no idea left.
Follwing situation. I have an GT-I9195 (LTE Version) on an older Cyanogenmod version (don't remember which one exactly) and got recently the "encryption unsuccessful" error during boot up. Okay, I know that's quite simple to fix, just reformat /data in recovery as ext4. But my old CWM recovery (6.0.5.1.) is not able to to change the file system and can not access /data at all (Error mounting /data).
Okay easy to fix - I thought - just update the recovery to TWRP and your good to go.
But doesn't matter what I tried, there is no way to change anything on this damn phone. And I tried a lot:
-tried to flash TWRP via Odin -->successful but no change on the phone (still on CWM 6.0.5.1.)
-tried to flash TWRP via Heimdall -->successful but no change on the phone (still on CWM 6.0.5.1.)
-tried factory reset and the whole story again --> no change at all
-tried 4 files stock firmware -->successful but no change on the phone (still on CWM 6.0.5.1. and on cyanogenmod with the encryption error)
-tried Re-Partition with separate PIT file with 4 files stock firmware -->successful but no change on the phone (still on CWM 6.0.5.1. and on cyanogenmod with the encryption error)
-tried Nand Erase and Re-Partition (4 files firmware) -->successful but no change on the phone (still on CWM 6.0.5.1. and on cyanogenmod with the encryption error)
So it seems I'm not able to flash anything. Tried different computer (with different OS), different cable, different Odin version (use 3.13 for the most trials but also an older one -->same results), so now I'm running out of ideas.
Might have something to do with "write protection enabled" or Bootloader version 2 or Kernel lock on 0x0...
This is whats written in the download mode:
PRODUCT NAME: GT-I9195
CURRENT BINARY: Custom
Knox KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
BOOTLOADER AP SWREV: 2
WRITE PROTECTION: Enable
Any ideas?
Thanks for your help!

i also need that man.
Please make one thing clear
Do we have to turn off "Auto reboot"
Or keep the "Auto reboot" option checked on?
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,

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.
