[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] balanadi:
I would like to share with you the latest original 4 files firmware J730GMUBU3ARB1 security pach 1 february 2018.

1. download the firmware J730GMUBU3ARB1 - Galaxy J7 Pro SM-J730GM PEO Peru from https://www.sammobile.com/firmwares/galaxy-j7-pro/SM-J730GM/PEO/download/J730GMUBU3ARB1/209612/

2.enter the phone in download mode and with odin place the AP, BL, CP and CSC

3. make the original setup in order to enter on developer options ( by pressing 7 times Build Number in Settings/About phone/Build Number) to activate OEM unlock and USB debugging

4. open ODIN Odin3_v3.12.10 and on the AP place twrp_3.1.1-1_j730gm_25817 from our friend ashyx[ https://xdaforums.com/galaxy-j7-2017/development/twrp-3-1-1-1-j7-pro-sm-j730f-g-gm-t3662621

Flash with odin in the AP slot.

Put your device in DOWNLOAD mode.

Uncheck Auto reboot.

Load the respective file below into the AP slot and hit start.

After flashing and ODIN reports PASS immediately reboot to recovery by holding POWER + HOME + VOL DOWN.

As soon as the screen goes blank change to VOL UP whilst still holding POWER + HOME.

You should now see TWRP recovery.

FAILURE TO FOLLOW THE ABOVE STEPS WILL RESULT IN TWRP BEING REPLACED BY STOCK RECOVERY

5. Format Data partition using FORMAT DATA button under Wipe options.

(Note: This will wipe the internal storage) ...FORMAT DATA... type YES , in order to delete the encryption on your internal memory

WIPE CACHE AND DALVICK

The next step is not necessary as i noticed that patching the boot image no-verity-no-encrypt_ashyx will cause a long delay in screen unlock , and if you don't flash this it will not affect the encryption of your phone as long as you did the formatting .

So i will not recommend to do this step 6

----6.install Boot image patch from ashyx no-verity-no-encrypt_ashyx https://xdaforums.com/galaxy-j7-2017/development/twrp-3-1-1-1-j7-pro-sm-j730f-g-gm-t3662621

WIPE CACHE AND DALVICK ----

Try skipping step 6 and go straight to step 7

7.install Magisk v16 the latest one

WIPE CACHE AND DALVICK

8.install SM-J730GM- 07.03.2018 the script to remove most of the bloatware

the script was modified by me on this firmware to make a very fast and no bug phone. If you want to keep some of the apk which i deleted with this script you can modify the script only with note++ (npp.7.5.4.Installer) by deleting the entire row of the apk

WIPE CACHE AND DALVICK

9.mount system and internal storage

10. you can copy the file others.xml from your sd card to system/csc

this others.xml was modified from the original one from this firmware to have more options like

air message,

ultra data saving ,

recording call button

EnableSmsCallbackNumber

DisableSmsToMmsConversion

EnablePromptToExit for samsung internet beta

and few more which you can see it opening this file with notepad

12. reboot the phone and make the setup

ENJOY

P.S. was made for my phone in order to have a very light and bugles firmware for my daily use , you can try and use it on your own risk .

I AM NOT RESPONSIBLE IF YOU BRICK YOUR PHONE, USE IT ON YOUR OWN RISK ...

THANK YOU ashyx

PS. I WILL NOT HAVE TIME TO ANSWER TO YOUR QUESTIONS FOR SOME TIME BECAUSE SUNDAY I AM GOING TO WORK ON THE RIVER CRUISE AND THE INTERNET IS NOT MY BEST FRIEND THERE.

HOPE YOU WILL ENJOY MY STOCK ROM AND WISH YOU ALL THE BEST...
