I would like to try flashing the stock bell rom back on my phone but I never backed it up initially.
I've been having Bluetooth music issues with both kernelpanics and ho!no!s roms so I have to get stock to test if its the phone or just the roms while its still in warranty.
Thanks guys!!

EDIT:
Found stock system.img
What are the ADB commands to flash the file to my phone?
Bump for new topic. Found System.img of stock bell canada rom
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14

when I type SU in, it says /sbin/sh: su: not found
and if i try dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
it gives me dd: can't open '/sdcard/system.img': No such file or directory
Okay, first, in CWM, you don't need to su for root permissions, your ADB shell has them. Second, if you haven't copied your file to the root level of your sdcard and if your file isn't named "system.img" exactly, that command will fail. I'll leave it to you to figure out how to move/rename your system.img file accordingly lol
Edit, it just occurred to me you might be having the garbled sdcard problem where it will spit out garbage if you type in the "ls" command in ADB. The solution has been posted by kernelpan1c, but first let us know what the output of ls is if you're sure your system.img is in the root level of your sdcard.

I already used ADB to push system.img to my phone's SDCard root directory.
Are you suggesting that I reformat my SDCard through windows?
I just realized that I am lacking the boot.img of the stock bell ROM. system and boot are the two that are absolutely necessary to get the phone working correct?
Which rom are you coming from? If it's a Nitro rom/kernelpan1c's rom, you shouldn't have to flash boot.img.
Yeah, according to kernelpan1c, there is something weird going on with the way our sdcard is formatted. After formatting it in Windows he says it should work just fine in the CWM flashed by Rom Manager (I haven't tested it myself, but I'm sure he's correct). I really want to know what is making the Rom Manager CWM unable to read it where bytecode64's CWM can read it just fine...

I think I'll be using HO!NO!'s rom as a base for the boot.img, since he has a bell optimus LTE, not the AT&T phone. I'm assuming that he hasn't made any changes to the boot partition, since no custom kernel development has occurred for this phone yet.
I found a so called legit CWM backup of the BELL rom, in one of the lu6200 threads, http://forum.xda-developers.com/showthread.php?t=1472501
but recovering the backup only hangs on the LG logo. I did a "advanced restore" and restored only the system and boot files but that didn't get past the logo either...
It booted after an advanced restore with the "stock" system(from that thread) and the boot (from HONO's), but the WIFI wouldn't start, it said error.
Where did you get your stock bell system.img? and can you provide it?

Mount sdcard in recovery.
After you enter adb shell
"mount /sdcard" (without quotations)
Then use the command "dd if=/sdcard/system.img of=/dev/block/mmcblk0p27"
Here is a link to the .img files. You can flash them using adb, but you will lose CWM. I am posting these in the hope that it will help someone who knows a little bit more about bootloader security and whatnot to make a CWM-compatible version.
The stock files are Here
Extract files to root of SD card, enable USB debugging and PC Software mode (if on LG rom)
Run the following from windows command prompt:
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
Restart,
Congrats, you've got the latest Bell release for the P930.

Used Rom Manager to install CWM.
Whenever I try to boot into CWM, i get the following error:
-------------------------------------------
Secure Booting Error
Cause : boot certification verify

Enter the fastboot...
Enter the fastboot...
Long time no see!

The ROM boots though, and has root access. Superuser works, and I am currently using titanium backup to delete the massive amounts of bloatware present in the rom.
I have attempted to flash recovery.img with CWM on it, but the error persists.
Anyone have any ideas as to how we can get around this error?

You must downgrade to GB before you can install CWM properly.
I just wonder if it works if you just load boot.img and system.img with adb.

You're welcome to try. I am too busy today, and I have started getting random reboots, so I'm switching back to Liquid Nitro.
Hi there!
I've hardbricked my s4 mini. If there is anyone with alive stock I9190XXUBNA1 (preferably I9190SERBNA1 CSC) - could you kindly help? I need dump of first 139008 blocks of bootloader.
If this helps - i will post an instruction.
How to dump:
Option 1 - adb:
get into adb shell and enter:
su
dd if=/dev/block/mmcblk0 of=/sdcard/file.img count=139008
adb pull /storage/sdcard0/file.img
Option 2: do the same in Terminal Emulator on the phone itself.
Upload that file.img to somewhere and give me the link. I will try to restore and if that helps - will do an instruction for unbricking.
Thanks!

Hi, i just want to ask regarding the recovery .img if is possible to flash it using custom recovery like twrp or cwm? i mean the one that you will see in the sd card you mention after doing the procedure in terminal emulator.
thanks

You can flash this recovery using Img Flash tool , Mobile uncle tool
Ok, next question...
Ok, so now that i have my boot image and recovery on my sd card, my device is the sm-t217a, now freshly rooted using the KingRoot 4.5 apk, busybox install, Supersume method. My bootloader is a locked bootloader. Im fairly new doing these things, so could you give me a hand holding guide to unlocking the bootloader if this will work for my situation.
