I successfully installed TWRP yesterday on my phone and then wanted to root it, but before doing that, I wanted to do a Full-Wipe of my phone, just leaving the phone with the OS, but for some reason, I left the System Partition Wipe option enabled and Wiped it. Now, I'm stuck in a bootloop without an OS, and I can only access TWRP and Download Mode.

How can I recover the system/install the OS again?

Phone Specs:


Previous O.S: Nougat 7.0

Region: México TCE

  1. Download the following file (J730GMTCE2AQJ1_TCE) from samfirmware.com: direct link
  2. Extract (unzip) the firmware file
  3. Download Odin v3.12.7
  4. Open Odin v3.12.7 (make sure to Run as administrator)
  5. Reboot your SAMSUNG J7 PRO (SM-J730GM) into Download Mode (press and hold Home + Power + Volume Down buttons)
  6. Connect phone and wait until you get a blue sign in Odin
  7. Add the firmware file to AP / PDA
  8. Make sure re-partition is NOT ticked
  9. Click the start button, sit back and wait few minutes for it to install the stock operating system.

  • Thanks for this! I'm going to try this, but I was wondering... what if I was already downloading that file with the SamFirm Tool, since I don't have any username on that page? Is it the same file? EDIT: I will update here If I have any complications :) – Alan Maldonado Dec 20 '17 at 22:36
  • Thank you, it worked! Now I'm going back to install TWRP and root it without deleting the system partition – Alan Maldonado Dec 21 '17 at 0:13
