Root [CWM] {AaronEmoBoi} One bug but fully working

A

Okay guys this is a how to on how to get CWM fully working.

First off i would like to thank tcaudill01 for first discovering this and i made an official thread about it and a how to because the way to get it has changed

Working:
Everything we need (such as Backups, Restoring, Flashing zips, and wiping )

The one bug:
You have to wipe cache Parition to leave the recovery everytime you want to boot back to system sadface i know but not too big of a problem

Steps to get it:

The newest Rom Manager made support for unsupported devices Which means we (being not on their list of supported devices ) can no longer access the Optimus Black's CWM. So i have an older APK of Rom Manager for you guys to use. Don't update the app if you want to keep the unnoficial support for our device

Step One: Download Rom Manager from my attachments to this post View attachment rmp4813.apk . The version has to be 4.8.1.3 or lower then load to SD card and install

Step Two : Run App then press on Flash ClockworkMod Recovery, find "LGE Optimus Black" then flash that one.

Step Three: Once its flashed reboot into it using Rom Manager or any other app that allows reboot to recovery such as Anreboot. Once its in the recovery you will get a bunch of error messages that says "Cant mount cache" or something along those lines

Step Four: at this point nothing in the recovery will work so what you have too to is go to mounts and storage and mount /system, then mount /sdcard, then try to mount /data if it doesent work then dont worry about it. it didint work on mine but you dont need to mount /data for it too work it would just help.

Step Five: Now go back to the main menu and wipe Cache Partition once thats done go to mounts and storage and see if /chache is mounted it will say "unmount /chache" if it is mounted

Step Six: If cache is mounted then reboot in to system and then next time you reboot in to recovery the error messages should be gone and you have a fully working recovery.

Now you will always have to wipe cache partition to leave the recovery until i fix it.

And when you press reboot it will sit at a blank screen for a while but will show the LG screen after 6 or 7 seconds no big deal

Ive flashed a kernal with this (which bricked my first Marquee ) and flashing does work ive made a backup and recovered it so that works and ive wiped the system so that works so yeah

Now there is no button combo to get into this recovery so if you brick there is no getting back into the recovery and you will have to use the LG Optimus Black's unbricking method but you need a special USB cord to unbrick so yeah. Don't be experimental and try flashing things from the international version of our phone unless you have the unbricking tools or insurance or you dont use this phone

Okay guys have fun its kinda long but sorry okay bye

If you guys would like to donate to me it would help me get more development going because i am barley making my phone bill happen and i cant test data and mms without sprint service so please help the cause as much as you can guys thank you

Interesting... may have to switch back to my Marquee for a bit and test in the near future.
Also, I know the Optimus Black does not have a button combination to enter recovery, but are you aware that the Marquee does (one of the few low-level differences between the two)?
Hold the Volume Down and Power Button until the soft keys start to flash, then release. Not sure if it will properly boot into a custom recovery / CWM / etc, but worth a try.
 
Here's an easier way.

Download CWM:
http://download.clockworkmod.com/recoveries/recovery-clockwork-touch-5.8.1.3-p970.img

Rename that file: recovery-clockwork.img
Place that file on your sdcard
With your phone booted and in adb shell type

su
cat /dev/block/mmcblk0p4 > /sdcard/recovery-backup.img

cd /sdcard
cat recovery-clockwork.img > /dev/block/mmcblk0p4

You still need to mount the data/sdcard/system then wipe the cache partion.

Yes, holding Volume Down and Power (with phone off) will boot you into recovery.
 
I have an old marquee that is flagged by Sprint as a bad ESN because $0.01 was left unpaid on my bill when the contract was up and apparently no way to pay the penny to get the bad ESN taken off.

I was thinking of changing this to Boost to give to my grandson for his upcoming birthday but need a boost CWM backup to flash.

So if anyone has a stock Boost Marquee CWM backup I would greatly appreciate a link :D
 
I have tried both ways to install Recovery,

Recovery Install is ok,

but backup start and finish very fast,

even size is not correct,

ls -l clockworkmod/backup/2012-02-11.02.38.21
----rwxr-x system sdcard_rw 5242880 2012-02-11 02:38 boot.img
----rwxr-x system sdcard_rw 5242880 2012-02-11 02:38 recovery.img
----rwxr-x system sdcard_rw 2048 2012-02-11 02:38 system.ext4.tar
----rwxr-x system sdcard_rw 2048 2012-02-11 02:38 data.ext4.tar
----rwxr-x system sdcard_rw 89088 2012-02-11 02:38 cache.ext4.tar
----rwxr-x system sdcard_rw 296 2012-02-11 02:38 nandroid.md5

any ideas:confused:

thank you
 
Im trying to look into that myself but i wiped to factory reset and restored and everything was there i think 4gb of data is not edited in any way when flashing and wiping so all it does is back up system and data with the boot and stuff. That being said i could be wrong im looking into it

I thought this sounded too good to be true.

A few months ago, Tcaudill01 and I were poking through memory dumps on another forum and trying to figure out why CWM wasn't working. He concluded that the memory mapping was different than the Optimus Black, which results in backup/recovery trying to access the wrong addresses.

Yes, it will look like it was creating a backup, however when you open it up, you would find only boot.img and recovery.img files inside (that would explain why some users here tried it and found their backups weren't the correct size). That's also why a recovery will usually brick the phone- it is not writing the appropriate addresses, and the only way to fix that would be to actually change the code within CWM.

I was really excited (and surprised) when you posted that CWM was working for you! I really want to believe it, but your solution seems too simple to be true.
You said the recovery worked for you- is it possible that your "recovery" didn't actually do anything (since it didn't write to the addresses that contain the data in question)? Perhaps it just looked like it worked because the data was still there from before (it never changed)? However trying to recover something else (kernel, ROM, etc) would brick it.

I mentioned before to tread with caution, there's a reason Tcaudill01 bricked so many devices and eventually gave up. I think we need to get someone who can pull apart the source for CWM and figure out what our memory mapping is supposed to look like. This, however, is beyond my pay grade.
 
Also, I would very strongly recommend that you update your first post.

First, to reflect that this may not be safe to try yet. Secondly, there is a key combo to boot into recovery (as I also mentioned previously).

Seems so stupid to me that LG would move all this stuff around in what is essentially the same phone. I wonder if it would be productive to compare the source code for the two phones and see if the differences between them might yield some answers.
 
I've been researching this issue for weeks now, and I *think* I've found a way to make a working clockwork. BUT I need the Stock Kernel for the Lg marquee. Ive tried looking into just extracting it from the phone itself but still cant figure out how.. If someone can find the stock kernel or let me know how to get it, i will be glad to try and help the community out. If i get the kernel and confirm that it does indeed work i will upload a zip file with a recovery installer.. So if someone can please help me get the kernel I will be happy to give it a go! thanks in advance :D

We already have one thanks to playfulgod look for his aio root and recovery thread
 
Alright, but i'd still like it if someone could direct me to the kernel because i think i can get us Touch recovery. Also i can't believe i couldnt find that thread. I've spent all day (not to mention weeks past) searching google and still came up with nothing.. i guess google doesnt always work.. and thats where the forums come in.. :)

Awesome! Thanks |Monster| Link me please :D Or you could send it straight to my gmail which is my user name @gmail.com.. Hopefully i can get this working.. it'd be nice to have the touch version in addition to the regular.
