How to Fix Sim cards didn't read for j730f /G/FM ALL Andriod phone - Samsung Galaxy J7 (2017) Guides, News, & Discussio

After updating Android Sim cards didn't read do not worry
Even when installed custom rom will work
Warning for everyone, No one updates Android about Official update
Because companies
force their policy on the customer in order not to install any custom rom

And then you can use any New Custom ROM It is not based on the old update Oreo ,
A Use GONESS but I hate this name
This site
You will find your phone's file (Stock Sboot) in this
Site https://shell.boxwares.com/
If any of these files fail
(Take the file (Stock Sboot) from any Firmware work on your phone ) :good: :good: This way works with any Android phone But you have to search (Stock Sboot) For your phone
After downloading one of the file, we open the Oudin program and then according to the file to be selected, we select the section:
-SBoot = BL
We turn off the device and then enter it into the Download Mode via the volume down switch + HOME + Power switch.
Then press Start to start the machine scan process takes about 30 seconds or less.
After the flash is finished, the device will automatically restart
If you encounter any problem in Android
Combination ROM Not all problems are solved by but some problems
This is information about Combination rom (You should read Important)
These ROMs are rare within the sites and are not published widely although they are complete ROMs and also from Samsung, but the company publishes them on a limited scale as they are not used for system update, but are used to fix problems only. Sometimes, problems with system files inside the device occur. It can be fixed using regular ROMs because it does not contain all the files specific to the device, so it uses full ROMs to completely delete all the contents of the device and re-put the system files and device definitions and bootloader inside it and for this it is not recommended to use them except for solving advanced problems and not for a process Only update.
These Repair Firmware ROMs consist of the following files:
PIT file This file may not come with all ROMs and is responsible for dividing the device and is not used to with devices appropriate for its size, i.e. if this file is for copies of 8 GB, for example, it cannot be used with a 16 GB space device as this device has a different file for it .
BL file ie Bootloader which is the file responsible for the bootloader files.
AP, PDA, or CODE file according to the ROM version, which is the main file and has a large size, which is equivalent to the ROM file, it contains system files.
CP, PHONE or MODEM file depending on the ROM version, which is the file responsible for identifying the modem of the device.
The CSC file is the file responsible for the country files the Rom is directed to.

Thanks!! It works perfectly only one comment, pay attention when downloading sboot file for your model in boxware page and be sure is the latest version. I downloaded the first in the list but it wasn't the latest version so it fail to flash in Odin.

Hi, I downloaded these files:
J730GDXS6BSD1_Stock_sboot_BoxWares.tar.md5
J730GDXS6BSD1_Stock_modem_BoxWares.tar.md5
Both are 8.1 Oreo, I flashed sboot in BL and modem in AP.
Only sboot is needed for sim to be recognized but I flashed modem because I notice some signal drops, so this last one is up to you.

Use the 8.1 one, but notice that it is the latest version, the file should look like this: J730Gxxx6xxxx the number 6 is important.

Thanks man. it worked! I tried flashing the stock sboot and modem file for android pie 9.0 first, just to make sure, unfortunately, it didn't work (sim card still not recognized). But when I tried the second time using the exact files you provided, it worked! Both Sims are working in LTE/3G. Thanks for the immediate reply and help man! Appreciate it!
