[Q] p769 - softbricked by noob - LG Optimus L9 P760, P765, P768, P769

i finally figured out how to get CWM installed and working, after a couple of months of fighting with it, off and on. so, i guessed that meant i have my bootloader unlocked - "wrong!".
i deleted some thing that wasn't supposed to be deleted, then the damned cell network and lan network stopped working (keeps saying com.android.phone has stopped). so i was going to put cyanogenmod on it, because i thought that i could, and just be done with the whole "missing apps" crap. it turns out "just because you CAN put CM on it doesn't mean you CAN put CM on it". i bricked it. i have NO options to "load" or "flash" or "boot" any thing when the phone is booting up. i would love some clarification as to what i CAN do from here.
i would rather install CM and be done with all of this, but i'll take any advice that gets rid of the problem. the biggest problem is understanding how to put CM on your phone, or to do any thing at all like that, when you cant get into any kind of recovery / boot menu, even though you ARE rooted... i don't care if i have to install cyanogenmod or some one else's CWM backup, i just don't know HOW to do it - especially with no windows (only linux). it's a rooted p769v20d (originally p769v10g).
thanks

i was going to try some stuff mentioned in other threads, but i don't have access to a windows computer - and i don't think i need to root my phone again any way, considering it is still rooted.

fwiw, regarding the mysterious deleted app:
i lose my internet signal as soon as it says "com.android.phone has stopped", then i get it back again right before it says that message again - it ALSO shows a cell-phone signal right before that message. this repeats over and over and over every few seconds - aggravating as hell...
here's the apps that i still have installed: http://forum.xda-developers.com/showthread.php?p=45774770

i finally figured out how to get CWM installed and working, after a couple of months of fighting with it, off and on. so, now i guess that means i have my bootloader unlocked?

Nice thread title. That is how I am feeling right now with this phone. I feel like calling tech care and yell at them for a bit to vent. Anyway, why not install fastboot for Linux and flash the ics u and x? I uploaded my u and x folder in the Unlock Bootloader for Noobs thread. Then, flash the 20h.....oh, dang.... sorry. Forgot.... no Windows. Maybe do the built-in restore by holding the volume down, home and power keys?

thanks, but i think i finally got it working. i never knew, after all this time, that after you do the l9recoveryinstaller, at the reboot, there are no cues to tell when when to hit some buttons, and it's not clear what buttons to hit. here's what i did, and, so far, its progress:
1: be rooted
2: install busy box, completely
3: install l9recoveryinstaller
4: reboot
5: after you see the LG logo, hold vol-down until you see the flashing lights (i thought you see the flashing lights and THEN you hit vol-down, but i was wrong).
still fighting to get a rooted rom installed ...
if i choose "install zip from external sdcard" is says:
"finding update ... opening update ... installing update ...installation aborted".
if i choose "restore" instead of "install" it will not let me select any thing, it just keeps saying file not found, when i try to select any further options, whether "restore" or "restore from external sdcard" or "advanced restore from external sdcard". and i already checked to make sure the sdcard was mounted...

I think your phone bootloader is locked, you cannot flash any custom rom zip file. It will soft brick your phone.
Please restore P769 CWM back from this thread http://forum.xda-developers.com/showthread.php?t=2136204. Download backup file and unbzip it. Put extract files in your sdcard /clockworkmod/backup/2013-08-30.12.00.00 folder. Extract file should contain several .img, .tar, .a, .log and .md5

Then try to use LG mobile support tool to recover your phone. Load it from LG website, start your phone to S/W upload mode, connect usb then start program and select recover phone from menu.

i don't have a windows computer. looks like i'm out a 350$ phone. lesson learned. never will cease to be amazed that so many mobile hackers are using windows... seems like they would be linux users too... that would be awesome, because then there are likely to be linux tools to do this with... and i don't have a windows img to load into a virtual machine... lucky lucky lucky...
thanks any way...

Well correct me if I am wrong, but I guess you "only" deleted some system files, right? Do you remember which ones were the ones? Or at least the folder they were in? Then you only need to extract that stuff from a kdz/ the bin file and push them on your phone using adb or maybe even the dd command.
Maybe if someone is kind enough, he ll probably provide you with the files you need. And cmiiw, but I guess you deleted stuff from /system/app...

Lol, you are a Linux user, you should know how to get your hands on a windows.iso
However, i would recommend using a portable windows xp (bootable usb)
VR is not the best option IMO
You will need this program http://unetbootin.sourceforge.net/
&
Sorry I can't provide a link to the iso but do a google search for
portable windows xp bootable usb Osheraj

okay, what do i need to download to load onto the phone? kdz images, right? i'll check and see if i can find a kdz in the forum, and borrow a windows computer. i think i got it - this thread: http://forum.xda-developers.com/showthread.php?t=2107971

It's depend on what method you use. You can flash kdz using offline method here http://forum.xda-developers.com/showthread.php?t=2085344
or use LG mobile support tools from LG website. If you choose this you don't need to download any kdz. It'll download kdz automatically from LG server then flash it on your phone. It take about an hour or two.

thats awesome - i wonder if i can get by with using that on wine on linux, instead of borrowing a windows computer... i'm gonna try it...

well, the verdict is in, on this one: i'm screwed. i've tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried, and i can NOT flash this damned phone. it's BRICKED.
i borrowed / hijacked my brother's computer (windows7), all day. i tried a few different things - i even tried the same way i flashed it to update it ( http://forum.xda-developers.com/showthread.php?t=2356536 ), which was worthless to unbrick it.
the problem in every case was that every time the damned flasher got so far along it would "lose the connection to the phone". drivers installed, etc, etc, no difference. i suspect its because i couldnt connect it in all the various modes (mtp ptp etc), since the ONLY way it would connect is in "software upgrade mode".
i had to buy another phone, won't have it till tuesday. lesson learned: NEVER buy a phone that didn't come from samsung... you just can't do what you want with them, without a lot of time, patience, experience, and a windows computer.
thanks for all the help.

Did you try to recover your phone with LG mobile support tool. It can reinstall rom in almost any soft-brick case. Please try it if you haven't try it yet. Many people restore their phone by that software. The steps are
- Download LG mobile support tool from LG web site
- Boot you phone to S/W update mode
- Run Tool and select recover phone
- Wait about 1-2 hours to download and flash
If it's not hardware problem, this should solve your problem

i never found that on their website, and i looked quite a few times. however, i noticed when i used the b2clientsetup.exe that if i run it without running the shttp server first, that it downloads a support tool from the net, which does not work - keeps saying phone lost connection. not sure if its the same tool.

Yes that tool. In my region, it has download link but for P769 it has request repair service.
Download from http://tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
You must remove following lines from hosts file
127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com
Then run it

yeah, that's exactly what i did, but it would keep "losing the connection to the phone". not sure why, but i suspect it was a driver issue - and i installed the latest drivers, which made no difference. i also went back and installed older drivers, which made no difference. i must just be lucky as hell, or some thing .

Try to use others USB ports, if that also doesn't work maybe you have to try on other computer.

yeah, i tried switching between the usb 3.0 ports and usb 2.0 ports, but it made no difference. i have no access to any other computers, so, that's why i ended up ordering another phone. i'll never buy another phone that is not a samsung...
thanks

In my country (RO) there are some GSM Repair Centers. You should not give up and you should go to them. Par example, I flashed an HTC Mozart when the battery was dead and I bricked it (idiot, I know). I went to a shop like the ones mentioned above and I think he said that he has to flash the phone using a JTAG or something like that (I know that he has to open the phone to reach it's motherboard, solder some **** out there and... flash I guess). The whole thing was about ~20E. Anyway, keep digging, maybe you'll eventually find something that works for you. If not, go to someone who can "force flash" it and maybe you can save the device.
