[Request] How to flash system.img through ADB in CWM

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"

[Q] Root gn gsm 4.0.4

Hey guys,
I flashed the 4.0.4 factory image today and was wondering how i can get root access without flashing a custom recovery since i want to stay stock atm.
I already tried the method i usually used (on 4.0.1 & 4.0.2)
Sorry can't post links... it's the normal method with fastboot and adb
and another method where you fastboot cwm recovery and then use adb commands but both didn't work for me
I can't post links so that's what i did there:
Temporarily boot into the Clockwork Mod Reovery using fastboot (on the computer)
fastboot boot cwmt-recovery-5.8.0.2.maguro.img (or whatever version you are using)
Mount /system using Clockwork Mod (on the phone):
mounts and storage -> mount /system
Chmod su using adb to turn on the setuid bit (on the computer)
adb shell chmod 6755 /system/bin/su
adb shell chown root:root /system/bin/su
adb shell ls -l /system/bin/su (permissions should now be -rwsr-xr-x)
Reboot. Super user should be working as expected (and your stock recovery is still intact)
Anyway,
I already spent much time to search on this forum and google so i was wondering if anyone knows any method which i could use.

You can root using this toolkit http://forum.xda-developers.com/showthread.php?t=1392310

Download this file to /sdcard, boot CWM like you posted, and then, once in CWM, flash the file you downloaded. Done.
EDIT: All that file does, is copy su and Superuser.apk to your device and set the appropriate permissions.

Thanks I'll try it, but I'm actually not a big fan of one click thingies where you don't know what you're doing.

This is what that file does:
Mounts the system parition
Copies Superuser.apk to /system/app
Copies su to /system/xbin
Sets permission on Superuser.apk to 0644
Sets permission on su to 06755
Sets a symlink for /system/xbin/su to /system/bin/su
Unmounts the system partition.

Just tried it and it worked just fine
And thank you for the explanation!
So actually you could do it w/out booting cwm just with fastboot+adb right?

No. You need root access on boot to execute those commands. CWM boots android with root access by default, so this allows you to execute the commands. If you do not use CWM, you can use any other boot image that gives you root access on boot.

Yeah i meant with another boot image which gives you root access, like the one i used to root the earlier builds.

Yes, you can use another insecure boot image, but it needs to be a 4.0.4 compatible kernel. Older ones won't work.

How to manually update with custom recovery and crypted mobile?

Hi there,
I have some problem with my GNex device.
I want to install a new ROM but I had to crypt my device cause of my company (damn exchange mailserver! don't find a cracked exchange for 4.1/4.2 ).
Now I can move the ROM to /sdcard but due crypting clockwork can't read it.
Any suggestions for me?
Tried sideloading with adb, but seems CW doesn't know anything about it.
Regards

Just found a way, for interested ones:
boot into recovery, plug mobile and let's have some adb fun:
Code:
adb shell mount -t tmpfs none /data
adb shell mkdir /data/media
adb push update.zip /data/media
flash via recovery.

[HELP] How to enable adb sideload in recovery mode?

I was following this thread http://en.miui.com/thread-183258-1-1.html for resizing system partition. ADB worked fine when phone was switched on and "adb shell" command worked fine. But when I rebooted into recovery mode and typed the same command I got this "/sbin/sh: su: not found" error. I tried to mount /system in recovery mode but in vain.
Please guide!
Thanks!

make sure u have rooted
boot into twrp
umount data cache and system and also disable mtp
use twrp filemanager go to system/bin chmod to 755 and copy parted to system/bin
now u can try adb shell
