Got fastboot working, but now what?

[MENTION=4447066]kuma82[/MENTION],

Before I start, I had NO IDEA how crazy the L9 was! I've rooted/unlocked/custom recoveried/custom ROMed 4 other phones without any major set backs prior to hitting this wall.

Also, this is my daughter's phone and I'm really took a lot of precautions before starting.

Here is what I did prior to attempting to wipe (factory reset) and install CM 10.1 (here):

Device model: P769

[was] rooted

CWM Recovery [was] installed

Stock JB (T-Mobile US) ROM backed up (full nandroid)

I was concerned about the many submodels of the L9 and verified both in the about phone within the ROM settings as well as what's printed/etched below the battery under the back cover. Both checked out to be P769.

I ran `adb reboot recovery` and then proceeded to wipe/factory rest from within CWM recovery. After this, I installed the ROM zip from the external sdcard. It failed the update script's assert of ro.product.id and would not install. OK, bummer, I'll just restore the nandroid backup. Nope. It was unable to restore /system and so now I really got concerned. I then found the weirdest thing of all. After seeing what is asserted in the update script for the ROM zip, I ran getprop for each of the properties it checks for and got back the Prada 3D "p940"! :eek:

Well now I felt like I was in a world of pain, so I decided to hack the update script so that "p940" would be accepted. Well now the install went fine without any errors reported. I proceeded to flash the latest gapps for 4.2.2 and it too installed fine. GREAT! Now for the system boot.........

From that point on, I've been stuck in LG Security Error land :(

I was able to get the special fastboot to connect (after many failed attempts) by selecting option 5 for ICS x & u flashing.

Could someone be please be kind enough to help me get my daughter's phone back to some ROM? I'm alright with even stock right now. At least then she'll have a functioning phone and I could even extract apps to restore from the CWM nandroid I made via Titanium.

peace.

To install custom rom or CM10 you need to unlock bootloader first. You should follow kuma82 in his post above to flash back stock rom.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The security error is because you didn't unlock it (sorry to hear that). Just flash with fastboot ice x & u for p769. Then put your phone in s/w upgrade and run the offline flash.

If you need anymore help, holla! I don't want your daughter mad at you ;)
[LG Optimus L9 P760, P765, P768, P769] erraggy:
I swear I read every link you posted above and still could not figure out what: "flash with ice x & u" is. I downloaded the fastboot zip and ran start.bat and selected option 5 for ICS x & u for p769 and that got me an inverted LG fastboot screen. I was also able to then choose option 1 for fastboot which dropped me into an empty yours directory.

It was midnight and I had at least 8 browser tabs open to various xda posts, but I still couldn't figure out what I needed to do with the start.bat next.

Thanks in advance. My weekend is dedicated to solely fixing her phone ;)
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
I've been wanting to try this: go to your computer and check your device manager and disable the LG drivers then try the offline flash again. Kuma way works but it's very long, found this while I was reading but never tried for our phones. Same problem though as updating stops at 15 %

Sent from my LG-P769(v20f) using the xda-developers app. Hit the thanks bottom, makes me feel good! :cool:

Another thing, more than likely, after you flash with the r&d tool you will need to do a hard reset because you flashed cyanogen. Also, you will still need to root to fix the touch screen.

CM 10.1 P769
[LG Optimus L9 P760, P765, P768, P769] erraggy:
Yeah, I was able to repeatedly get the inverted LG fastboot screen and see everything you saw in device manager as well as successfully get `fastboot devices` to show (echo) the device. I even tried `fastboot flash recovery p4_769.img` with the file linked in post #3 and it flashed without error.

Here's my problem: What do I need to do now that I have a working way to run fastboot commands? Is there a recovery image I need to flash (stock)? Is there a boot image I need to flash? Or, is there some other fastboot command I need to run?

I'm assuming the advice you're giving me is to ultimately get a stock ROM back on her phone. Is that correct?

I'd really like to unlock the bootloader so that I can do what I know with CWM: backup, wipe, restore, flash, etc... If that is something I can do from where I'm at now, I'd prefer to put the effort in to that. If this darned 'Security Error' splash message must be resolved by getting back to a stock ROM first, then I'm game.

Final request for clarification: Am I still needing to "flash the ice cream x & u boot for your device (in fastboot) to get the offline flash running again"? If so, could you please provide instructions for that step? So far all of the steps linked here have been to get Windows drivers sorted out and fastboot working. I've got that now.

Thanks again!
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Okay, did you get all your info about unlocking the bootloader from carloswii5 video? So you had flashed 20b kdz right?

You gave me a hand full Lola, but I'm help you out. It get is going to take me some time to give you a guide, but I'll give you everything you need today and yes, you need to get back to stock.

I'll send you another link on how to use fast boot manually. Plus it has the images for ice cream. But hold up
[LG Optimus L9 P760, P765, P768, P769] erraggy:
THANKS!

Her phone had the stock TMOUS jelly bean ROM that we received OTA. I had only rooted her phone previous to my CM10.1 fiasco attempt.

So I've never flashed anything (successfully at least) on her phone. All of my previous android experience has been on 3 nexuses (One, S, 4) and my current HTC Sensation. That means I've only unlocked one bootloader that didn't support the fastboot oem method ;)

I'm an experienced dev with the entire weekend to "play" with my daughter's p769 :D

I also promise to provide lengthy posts in the Optimus L9 forums to help any future people from soft bricking any more devices.

This will tell you how to use fastboot manually http://xdaforums.com/showpost.php?p=43642515&postcount=21

The system image is to big to flash with fastboot, sucks.

1. Use the above to get back on stock (you need 10g kdz).

To enter s/w upgrade remove battery. Hold volume up and enter USB cable, then put the battery back in.
[LG Optimus L9 P760, P765, P768, P769] erraggy:
UH OH... The "volume up" method isn't working on this device. I posted more details about it here. I'm beginning to think I may need to return the phone. I never thought flashing a ROM zip in CWM recovery could brick the phone. When I restoring the CWM backup also failed (when I at least was in CWM recovery which now is inaccessible), I freaked.

P.S. - I'm all out of thanks for the day. I think you got the lion's share though ;)

So you manually flashed ice partitions?

You might have forgot to flash the u-boot. The u-boot is needed to enter s/w mode.

[LG Optimus L9 P760, P765, P768, P769] erraggy:
ZOMFG! FINALLY Got it to load s/w upgrade mode! It took me checking all 3 USB ports as well as switching the USB cable to finally get it to load it up. I then was able to follow the full [GUIDE] [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX successfully.

Her phone is now restoring all apps via Play Store. One issue so far is that it is unable to connect to T-Mobile. I have it currently on our WiFi, but looks like something is up with the radio. And before I even finished posting this I think I figured out why.

I loaded V20F but not the T-Mobile version :/ I'm downloading the T-Mobile USA V20D kdz now.

I cannot believe how much trouble I've been having. Adding to this my own errors is just rubs salt into my wounds.

Thanks for sticking with me [MENTION=4447066]kuma82[/MENTION]!
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Glad you got it operating. I didn't know anything about another non t-mobile 20F kdz. Well I hate to tell you but the best thing to do if you plan on unlocking. Is to flash 20d but extract the u-boot from the kdz, and flash it with fastboot. 20F u-boot does not get overwritten while flash (R&D Tool) 20b kdz. You need the inverted lg logo (20b u-boot) at boot for the unlock to work. I have no proof but that is what I would do.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
No problem bu bu buddy ;) not having the bootloader unlocked is a pain in the (@).

You have to rely on the R&D Tool & and a 2nd init recovery (which isn't very reliable as you know).

[MENTION=3341670]erraggy[/MENTION]

I'll give you the steps here, I feel bad because you couldn't unlock it, but this will help with the sting.

1. Download and install 20f cwm backup from from carloswii5 https://www.dropbox.com/s/vq5ar1m91ykrrwm/2013-07-15.19.04.zip

2. restore touchscreen with Lelus zip (you should have this if you got everthing from carloswii5 guide)

3. fix u-boot with my flashable zip

4. Flash proper radio in cwm, this will take awhile.

5. Add app2sd by editing the build.prop add this to it ro.lge.capp_move_sdcard=true
[LG Optimus L9 P760, P765, P768, P769] erraggy:
THANK YOU! ! !

I'll post the details of how the steps went tomorrow (well later today since it's already after midnight here) after I get some sleep. :D

Bottom line: unable to unlock the bootloader, but my daughter now has stock jelly bean, rooted, with the ability to move apps to the sdcard. Awesome!
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Don't forget the swap script ;)
[LG Optimus L9 P760, P765, P768, P769] erraggy:
DOH! LOL

Well looks like I will be back to a late night hackathon with her phone tonight. This process looks fairly straightforward, and consists of mostly adb and linux bash commands which I can do from my macbook and I'm really comfortable with. :good:

Just to be clear though, this is the thread you were referring to yes?

How to exchange memories​

And thanks again :D
[LG Optimus L9 P760, P765, P768, P769] kuma82:

Also there is an app that does the same thing (mount2sd) but I always used the script.

I used that to get to fastboot but i never got a confirmation to unlock
[LG Optimus L9 P760, P765, P768, P769] xdrc45:
You don't use the fastboot script to unlock the bootloader. You need to follow one of the unlock bootloader guides in the L9 general forum to try and achieve the unlock. This is a very lenghtly proccess and there is no guarantee that you will be successful since LG has encrypted the bootloader on the L9's built in the last year or so. I recommend researching, reading and even more reading and to have all the necessary files and kdz's before beginning the process.

The actual command to get to the bootloader unlock screen is thought adb command:

adb reboot oem-unlock

Then the phone will reboot to a confirmation screen to issue the unlock.

Good luck!

Hi xdrc45, this is the correct adb command

[LG Optimus L9 P760, P765, P768, P769] xdrc45:
If depends on what kdz version your P760 is currently on and what method/guide you use to try and unlock the bootloader with. On a positive note it seems that members with the P760 were more successful at unlocking their device than on some of the other L9 variants.

One of the unlockable kdz version was the v20B Europe open.

after extraction you shall get two files: I9082XXUBMGA_I9082OXEBMGA_I9082XXUBMGA_HOME.tar.md5 and SS_DL.dll

i was already running on the leaked version of 4.2.

I DID NOT WIPE CACHE/DALVIK/SYSTEM/DATA so you may call this as a dirty flash.

entered into download mode..

connected odin. loaded the earlier extracted official rom (I9082XXUBMGA_I9082OXEBMGA_I9082XXUBMGA_HOME.tar.md5) on pda.

then simply click start and wait for 5-10 mins.

make sure not to click restart on odin.

when the download is done.

flash the kernel available on the samsung site through odin.
