Root CWM Recovery for LG Spectrum

[mtmichaelson]

Test the .bat? Is it just to back up the stock recovery and flash cwm?? If so I will first thing in the a.m.

I will send you a link in a pm. It is actually an all in one .bat. There are 7 options in the menu (root, root & cwm recovery, cwm recovery only, unroot, unroot & stock recovery, stock recovery only, and reboot into recovery). Let me know how it works for you! Thanks!!!

Just tried it so far rooting works no recovery working yet... Hangs up on mounting as operation denied... Is there a way to request su before trying to mount -orw

Is there a way to put the local.prop back. Because whenever i do the rm /system/etc/install-recovery.sh command i get an error in adb that says no such file in directory. but i am able to install cwm and boot into recovery over and over if i want to. Ive restored my phone many times now and that file is no longer there for when i do the above command. and idea whats going on here.

You only need to remove it once. Once its gone, its gone.

Even after flashing the stock cab file??thanks for clearing that up for me

The cab file should replace it so, that is odd.

/data/local.prop is a system created file, not something created by LG. With that being said, anything that you (echo "text" > /data/local/prop) would be put in to the file and if the file does not exist, it will create it for you. This is useful as having certain statements inside of this file will automatically give any adb connection root access. The down side is that it gives "everything" root access and should not be left in place for long periods of time. The same goes with remounting /system as RW. Any time you do a remount, you should finish what you are doing quickly and either full reboot or remount /system as R only.

I haven't seen the script yet, but I have yet to see a way to issue a SU command from "adb shell" unless you are already in shell or you have the correct argument in /data/local.prop . You could manually go into adb shell and then su and do the argument, but that would defeat the purpose of an automated script. The other alternative, would be pushing a .sh script to the phone and having it run and do all the commands internally. Again, I have not seen the script yet, so I could not tell you which it is currently doing.

 

[atomilluminati]

I think between myself and mtmichaelson we may have figured it out... Still waiting on a response from him and after we talk we will let everyone know....

wtf you learn to make recoveries??? No offense, but recovery is not something you just hack together. The source for building CWM is OPEN SOURCE and there are plenty of guides, including one from koush explaining how to port it correctly.

Second wtf is a page? If you are referring to the p in like mmcblk0p12, it stand for partition!!!

I'm not trying to diss you, sorry if it seems like, but rather I am trying to inform you a lil.

The big thing with recovery is having the recovery.fstab correct and the partition sizes etc in the boardconfig.mk. Some times esp with LG devices there are 2 files that need deleted for a custom recovery to boot and a cmd in /misc that needs zero'd so that data doesnt get wiped when booting to recovery via the button combo.

I am working on a proper port as I type this. I will update when I have sumtin to test

More power too you. I would love to see an official version from source get made. It would mean less threads about people getting stuck in a boot loop and perhaps even Koush hosting it in Rom manager, so people would stop trying to flash the Nitro Recovery.

Oh when it goes official koush has it hosted n it will be avail from RM, and prolly even have the touch avail too.


Now does anyone have a stock boot n recovery.img???

I grabbed one from the spectrum files mirror but it doesnt seem to be it, or it corrupted one.

thank you!

 

[PlayfulGod]

oh happen to have a list of mounts and partitions?

And does the spectrum have an internal sdcard? aka internal n external storage?? If so could I get some one to open the internal storage from the file mgr and then from adb shell do:

 adb cat /proc/mounts

and post here in

 tags plz. ;)

Here's your base info, plus stuff I have found over time. The items in brackets are what .tot file calls each particular partition. /"name" are true mount points from the phone. Also, no, we do not have combo (internal and external) storage like the Atrix, just external storage

 

[PlayfulGod]

k thx.

Better to be picky than have bricks

 

[PlayfulGod]

k, now I need a dump of the stock misc partition.

Needs to be bone stock, not from the bootloop fix or BrokenOut.

dd if=/dev/block/mmcblk0p25 of=/sdcard/spectrum-misc.img

The one in boot loop fix IS stock. How else do you think we're clearing all the flags.

kk, just need to be sure.

theres another way of clearing them with a script too, hence why I wanted to ensure I had a stock one were I can find the correct offsets.

Nevermind stupid question
