SU640 tested！

It does working！！

Thank you @bytecode64！！
[LG Nitro HD] V@no:
Hmmm I think something wrong with the "fix permissions".

I got again into boot loop, then in CWM cleared dalvik cache, after that run fix permissions and it froze. Then I forced phone reboot into recovery again, run straight fix permissions, it finished in a 1/2 sec, rebooted, got stock into LG logo, and now it would not boot into recovery anymore, it shows black screen and boots normally...
[LG Nitro HD] bytecode64:
There should be a log in your sdcard/internal memory , if you can send me this also send me your last_log in /cache/recovery/
[LG Nitro HD] aquariuz23:
LOL!! N my name is also included in the "Thanks" list, while I don't think I did anything to help at all, other than moral support I guess? HAHAHA. Anywho, thanks for adding us on it :) I've never been included in anything before here on XDA; this marks a new day for me here :D

Bytecode, thank you very much for all your hardwork! You just earn yourself a spot on the VIPs of Nitro HD Development Team! lol!

Next in line, CM9 PEOPLE!!! Let's get Cracking!

P.S. Since we have managed to port CWM to the Nitro, to make it more legit, can someone post an image of it on the phone so Bytecode can post it on the first post. This way, when XDA or any other site does a story on this, they have a picture to post as well for people to see :D

---------- Post added at 08:07 AM ---------- Previous post was at 07:47 AM ----------

I have also informed Engadget about this. Previously, they've covered the Atrix being rooted as well news regarding it. Hopefully they will cover this one as well. We really need those pictures :D I'd do it, but I can't port CWM rite this moment lol.
[LG Nitro HD] kernelpan1c:
For some odd reason, running "cat bc64-recovery.img >/dev/block/mmcblk0p13" didn't flash CWM recovery for me. I'm a Linux user so I'm well aware of what these commands do. I powered off the phone, booted into recovery, hit one of the volume keys so not to do a master reset, and then the phone just reboots into Android.

I thought maybe I downloaded a corrupt file from the link in the OP, but I re-downloaded, did the cat command from the first post again, still couldn't get into CWM. I finally used dd:

Edit: That didn't work either. I can use "reboot recovery" in adb to get to CWM recovery. But using the power key+vol down still doesn't boot me into CWM.

Edit 2: Ok, I re-watched the video. So you DO want to confirm wiping the phone by pressing the power key twice. That then gets you into CWM.

OP, could you please add that to your first post? I think that would be helpful to others.

Keep up the good work!!

Backup and recovery worked for me as well. I did a controlled test and just changed some things on my home screen. Everything is perfect since my restore.
[LG Nitro HD] aquariuz23:
Btw guys, kennethpenn of Briefmobile.com responded to the Reddit post Malnilion did. If someone can convince him to post this story as a news on his site, it will be quite a great thing too :)
[LG Nitro HD] V@no:
Unfortunately it was not possible, the phone was in boot loop and adb didn't see it. I had to go through unbricking solution with LG SU-640 firmware :(

Hopefully restoring backup will bring the phone back to normal (dumb me did not backup all partitions manually when I had chance...)
[LG Nitro HD] netnerd:
another way get into recovery is get Quick Boot from market.
[LG Nitro HD] dbjungle:
I use this too, it's pretty awesome.
[LG Nitro HD] bytecode64:
so you cant enter into recovery anymore? , if you still can enter into recovery , you can just do a quick restore of the stock images (img) (using adb)

cat image.img > /dev/block/mmcblk0px
[LG Nitro HD] blaineball:
Did multiupload get raided lol... the link seems to be dead.

That aside, great job bytecode64... this phone just got better!

[LG Nitro HD] V@no:
This is something weird. I don't know what happens, but again it would not enter into recovery anymore. Same symptoms I've had before - animation boot loop and attempt enter recovery would simply boot normally (after flashing black screen just before the CWM text appears). But this time before it happened I did absolutely nothing, just powered down the phone.

Fortunately I managed recover it by doing the following steps:

1) unplug the phone

2) remove the battery

3) put battery back

4) plug phone to USB charger

5) let it "boot" into battery charging screen

6) press and hold POWER + VOLDOWN.

I might have unnecessary messed up my phone with SU640 flash now

P.S.

another method enter recovery now is through Settings -> Privacy -> Factory reset

:)
[LG Nitro HD] kernelpan1c:
I cooked a ROM using my system.img backup and it looks like the it won't flash because the script

1. cant format /system

2. cant mount /system

I don't believe its my updater-script, but I'm checking with another dev.
[LG Nitro HD] bytecode64:
The system is ext4 fs, by default its mounted on boot (with read write) are you sure that your script is using the ext4 (-t param) to mount , format it?
[LG Nitro HD] dbjungle:
CWM has already saved my tushy. Just got my 32 GB class 10 SD and after inserting it my phone got stuck on the AT&T screen. I pulled the battery and afterward it refused to go past the second LG screen. Recovered my ROM from Friday and I'm back in business!
[LG Nitro HD] kernelpan1c:
That might be it. I manually used recovery and adb to copy over my deodexed framework and app files (deleted the original and cp'ed from sdcard to /system/app and /system/framework). Everything boots, so thats good.

As soon as I can figure out why the update zip isn't flashing, I can release a de-odexed and de-bloated stock ROM if anyone is interested.
[LG Nitro HD] bytecode64:
Ok , ill be also porting RZRecovery (http://rootzwiki.com/topic/7309-recovery-rzrecovery-many-devices/) for nitro :)
[LG Nitro HD] aquariuz23:
Now wat's dis bytecode? :)
[LG Nitro HD] bytecode64:
heh another recovery :P , more features than cwm :)

That text centered on screen is hurting my brain...why people do that?!
[LG Nitro HD] gte460z:
I am definitely interested!

RZRecovery looks interesting too!

I am waiting for deodexed rom to fix RTL-languages.
[LG Nitro HD] V@no:
Found another issue:

after factory reset or manually format /data or /cache, these partitions get unmounted, if you try mount them, CWM no longer works until rebooted.

Can't reproduce it again after reflashing recovery, must be a one-time-glitch or something.
[LG Nitro HD] V@no:
False alarm, something went wrong with my phone, it would get into boot loop even after normal reboot. Even factory reset would boot normal once, on second reboot it would get into boot loop..

Just did reflashing all partitions again, it fixed the boot loop, however "fix permissions" still messing up text
[LG Nitro HD] bytecode64:
hmmm strange :S , anyone else can confirm this issue?
[LG Nitro HD] dbjungle:
My phone isn't messing up text, but I am having the boot issue. It's specifically when the power is turned off. I can reboot as often as I like, but when I power off my phone I can't boot up normally afterward until I run a recovery.
[LG Nitro HD] bytecode64:
hmmm probably something to do with postrecovery.sh (currently there is none , required for clearing misc partition boot command)
[LG Nitro HD] kernelpan1c:
Any chance in getting advanced backup to work? (ie the one where I can just select only backup /system?)
[LG Nitro HD] kernelpan1c:
I fixed my updater-script, it now flashes!!!!

[LG Nitro HD] gte460z:
Nice! Get a thread started so we can start playing with it!
[LG Nitro HD] kernelpan1c:
I've started a thread, PM me if you want an early beta and help test.
[LG Nitro HD] lordlittlebrooks:
Followed the instructions in the OP and it worked like a charm! Bytecode, you are the man! Backing up as we speak. Can't wait to flash kernalpanic's rom!
[LG Nitro HD] dbjungle:
I'm unable to get into CWM anymore and I'm stuck on an LG boot loop. I can still start up recovery mode, but after the warning screen it doesn't reboot into CWM. I hope I'm not the first casualty. Does anyone have any idea? Is it possible to re-flash CWM from download mode?
[LG Nitro HD] bytecode64:
Ok people having issues with boot loops etc , ive updated the recovery , most probably it will resolve the issues

@dbjungle

from fastboot : fastboot flash recovery bc64-recovery.img

(img file must be in your sdcard)
[LG Nitro HD] dbjungle:
That sounds much easier than running the KDZ. This is a bit of a newb question, but how do you fastboot on the Nitro?
[LG Nitro HD] V@no:
@dbjungle:

Try this: disconnect the phone from usb, pull out battery, then put battery back in and plug in wall charger. Wait until it boots into battery charge screen (hopefully), then press and hold power+voldown

I've been getting boot loops constantly for last 2 days, in fact the backups that previously worked no longer work and each time I reinstall rom after few reboots it would get into boot loop again. With each time it happened it was getting worse and worse, up to the point when battery charger screen no longer appear and PC didn't see the phone. So I had to go through kdz unbricking.

Hopefully new cwm version fixed this.

From what I could tell, Nitro doesn't have fastboot...or am I wrong?

Speaking of flashing partitions, what is the difference between these two methods?

cat /sdcard/bc64-recovery.img > /dev/block/mmcblk0p13

dd if=/sdcard/bc64-recovery.img of=/dev/block/mmcblk0p13

P.S.

just curious, what recovery has to do with boot loops?
[LG Nitro HD] kernelpan1c:
The two commands with dd and cat should in theory do the same. I think dd is the "proper" way
[LG Nitro HD] dbjungle:
I was under the impression that most if not all Android devices would have some type of fastboot support. I'm going to try it out tonight when I get home. I'm leaving work pretty soon here.
[LG Nitro HD] scott0:
I can verify the nitro does have a fast boot. I accidently entered it while using Malnonions unbrick guide. I have no idea how though, sorry.
[LG Nitro HD] dbjungle:
I'll read that guide, maybe I can find what I need. I'd rather not restore from the kdz if I can avoid it.
[LG Nitro HD] bytecode64:
cat is simple (specially when you have complete partition backups) , as for the bootloop , the first 84 bytes of the /misc partition contains the boot command that needs to be cleared out before rebooting , atleast that is what i can figure out
[LG Nitro HD] dbjungle:
Ran the V10i_00.kdz and flashed all the images to my phone. Now I am 100% A-OK. Making a backup then I'll restore my ROM from earlier too. I'll also check to see if I'm still getting the loop after using CWM and reply back. Thanks for all of the great guides!

---------- Post added at 02:49 AM ---------- Previous post was at 01:52 AM ----------

I'm still having the loop after running a recovery with the CWM update. I can get back into recovery if I take the battery out. It seems to be more consistent if I plug into the wall charger and let the battery charge screen come up before trying to boot into CWM.

If I restore, whenever I power off, on next boot I won't get past the AT&T screen (it loops). If I take the battery out and try to boot into CWM, sometimes I'll go straight in and sometimes I'll get stuck on an LG loop going into the second LG screen. This problem doesn't happen if I reboot as opposed to powering off.

Currently my phone is functioning properly outside of that just like yesterday before I soft bricked.
[LG Nitro HD] Reviewers:
It's pretty amazing, everybody enjoy this wonderful piece.
[LG Nitro HD] schwin97:
@bytecode64 - Did you run mkbootimg to create the recovery.img, and if so did you have to specify the '-cmdline' option? Could you share how you did that as I would like to play around some in the recovery image, and this is needed to recreate an image that works.

Thanks!
[LG Nitro HD] bytecode64:
You can find the CMD line in BoardConfig.mk

should have something like android.hardware = qcom at end
[LG Nitro HD] bytecode64:
Ok for users having bootloops under normal boots and can enter cwm recovery, you can help me resolve the issue by posting kernel log here :

1) Normal Boot

2) Going to recovery mode after it restarts (IE first Boot Loop)

3) mount sdcard from recovery

4) connect phone with pc and exec the following command through adb:

cat /proc/last_kmsg > /sdcard/last_kmsg

5) post the last_kmsg file here so that i can debug
[LG Nitro HD] aquariuz23:
Hey guys, can someone help me with this please? I'm not very good with these things and I think i messed up somewhere. Nothing severe as I can still boot back into my phone normally. However, after following the steps above, when I reboot and hold down pwr+vol. down button, I don't get a prompt to do a factory reset. I just get a LG logo, where I press n hold the power+vol. down button, and then the LG logo disappears and quickly the logo comes back, and even if I press the power button twice or continue holding the combination buttons, it just continues into the AT&T logo animation and then a minute later boots into the phone.

I dont know where I went wrong. Here are the steps I did:

Then I just reboot the phone, and attempt to go into cwm, with no luck. Please help.

p.s. just checked through root explorer under sdcard, and I find the recovery-backup.img so things should be working. I don't know what went wrong.
[LG Nitro HD] dbjungle:
Try taking the battery out then doing it. If you still can't do it, you might want to try to re-flash it when you boot back into Android.
[LG Nitro HD] V@no:
You do hold both power and voldown buttons until second lg logo shows up, right? Otherwise that is the problem.

[LG Nitro HD] dbjungle:
Just wanting to know the general consensus from all Nitro users. Is format /system in CWM safe? The reason I am cautious and asking is because the last time I did this I soft-bricked.
[LG Nitro HD] schwin97:
You shouldn't need to as most roms will format system for you.
[LG Nitro HD] gte460z:
yes, formatting /system is safe.
[LG Nitro HD] V@no:
Is sdcard mount and wrong timestamps something hard to fix?

And by the way, is it normal that after backup system and data partitions stays unmounted?

At this point it doesn't matter what you select there, because you'll need go to settings -> applications -> development and enable "USB debugging", it will automatically select "PC software" mode for you and that's what you need.
[LG Nitro HD] blopez24:
Ok got cwm to work, now to begin the flashing!! thanks Guys.
[LG Nitro HD] dbjungle:
Can't wait to try this too.
[LG Nitro HD] V@no:
I will test it myself over weekend, but until then maybe someone who is in process unbricking their phone (because of boot loops after shut down, or simply has nothing better to do...), could test this: restore the phone to the point that it boots after reboot, but boot loop after shut down.

So at that stage restore stock recovery partition, reboot, make sure it still working, then shut it down, will it still boot loop? If it does, then we could rule out CWM as the cause of it...
[LG Nitro HD] dbjungle:
Yeah I'm not sure what the cause is, but when I bootloop I can restore with CWM. I only soft bricked after format /system. It seems like a freak accident cause I have done it multiple times since.

delete account

OK so I bought LG nitro rooted from a Guy. Installed cwm. And than backed up ...than flashed a different rom...all is good....but his Gmail account is still there. I went to accounts and sync. Tried remove account but it said I had to do factory reset...I know forums say not to do that...I restored stock rom. From backup...went to privacy did factory reset erase all phone data...phone restarts. Than ends up in cwm I choose reboot system..and than it just goes back to rom. How do I delete his dang account. ???? :confused:
[LG Nitro HD] V@no:
If you are using stock rom, then factory reset from CWM should work just fine.
[LG Nitro HD] SolsticeZero:
Reflash the stock recovery and then do a factory reset. That will get rid of it.
[LG Nitro HD] youngv408:

Ive gone back to the stock rom... unless i have to get rid of cwm first. Or maybe its the room because the rom that was being used when i got the phone actually doesnt look like the original...... and the launcher is just adwlauncher... hmmm..... does anyone have thevoriginal that i can download ... and how do i flash it... is done through adb process ???
[LG Nitro HD] SolsticeZero:
Follow the steps in here:

But ONLY DO THE RECOVERY.IMG! That will put the stock recovery on, and then you can do a factory reset. That will wipe all of the previous users data.
[LG Nitro HD] V@no:
CWM can wipe user data as well as the stock recovery.
[LG Nitro HD] SolsticeZero:
I thought wiping /data in CWN bricked the device. Or am I just a bit out of the loop? I've been gone for a couple of days.
[LG Nitro HD] youngv408:
So i done have to do the 640rom mumbo jumbo... just push the recovery. Img and than restart phone...?

Pretty much i jus download the recovery. Img... plug phone to pc... drag and drop the file to sdcard.... than follow step adb shell ... su...

Can i just do that command via terminal emulator?
[LG Nitro HD] SolsticeZero:
Exactly, that's all you need to do. Forget the 640 stuff, that's unnecessary. Just put it on the SD card and do the DD=blah blah blah stuff.
[LG Nitro HD] youngv408:

much more complicated than that. rooting was not the problem, it was a symptom. there are issues when using CWM with the Domination ROM and that point does belong in this thread along with all of the other posts in this thread that point out any issues with the cwm mod.

Something wrong with this CWM

I use this recovery_script:

ui_print("Applying framework-res.apk");
run_program("/sbin/busybox", "mount", "/system");
delete("/system/framework/framework-res.apk");
package_extract_dir("framework", "/system/framework");
run_program("chmod", "0644", "/system/framework/framework-res.apk");
run_program("/sbin/busybox", "umount", "/system");
ui_print("Applying SystemUI.apk");
run_program("/sbin/busybox", "mount", "/system");
delete("/system/app/SystemUI.apk");
package_extract_dir("app", "/system/app");
run_program("chmod", "0644", "/system/app/SystemUI.apk");
run_program("/sbin/busybox", "umount", "/system");

As an experiment I used unmodified SystemUI.apk and framework-res.apk

After installing both new files have proper permissions and MD5 checksum, however phone either get's into boot loop, or gets stuck at LG logo.

Any ideas?

thanks. I'm a little scared by the big red warning in custom rom thread.

Hope the bug to be fixed soon.
[LG Nitro HD] V@no:
Today I'm starting over with fresh all partitions, will not install CWM at all and shall see if normal use of the phone (after restore everything with titanium backup) will brick the phone. If not, then perhaps we could try use adb to push roms (aka restore system.img) and see if that bricks the phone. At least this could potentially prove that CWM itself is the culprit of all our problems here...
