[Q] Problems with Downgrading L9 - LG Optimus L9 P760, P765, P768, P769

Hello everyone
I am new to LG phones but quite familiar with modding Sony phones, as all of you know that there are many problems with L9 like not able to move data to sd card, Touch screen sluggishness sometimes and not able to mount the memory card but many of them can be fixed via rooting. But again only V10a and V10c are rootable, i have v10d P765 IND version. I want to degrade the firmware so that i can root the mobile and play with it properly.
I followed the guide KDZ offline flashing method but I am getting error
"cannot connect to internet , check the cable line"
I am following every step, Does anyone know what is this?
Thanks in advance :fingers-crossed:

well did u run shttps ?
did u run windows enabler to ON ?
did u installed proper drivers for phone ?
did u turned of lg pc suite ?
did u installed proper lg mobile support tool ?\
did u instaled android sdk (not required but... still good to have it)
and the most important did u readed the tutorial few times ?
if u have checked all steps as YES then everything should go well.
Just check everything again.
Btw i also get that info when i dont turn on shttps !

PROblem persist
Thanks for the suggestion,
I did everything thats said in the tutorial, flashing started but stopped at update saying, problem with communicating device and PC. as told i tried both modes
1. usb debugging on (mobile normal)
2. software update mode (by holding vol up and connection)
but the problem persist.....i have installed every single driver i supposed to insatlled, but bro its really frustating....I really want to root ....or i have to sell this mobile by swearing never to buy LG mobile...

Your first problem (Please, check internet line and execute program again.) is solved. Correct?
And now you got a "cannot connect to phone" message, right?
Did you try to connect to your phone with LG PC Suite. Because if you can connect and sync your phone then all driver is installed. Download at your local LG website ex. for me http://www.lg.com/th/support-mobile/lg-LGP768F#software, in PC Sync Tab
If you install all drivers when you connect to your PC, you should see new 2 drives (Phone internal SD and External SD)

NOT solved bro
the problem came again, it start showing check the internet cable again.....
i dont know what the problem is?
it worked once but now its not working. It seems that my shttp isnt working properly because i can connect the mobile via internet and check the update, when offline it start showing that again.
Btw i am using automatic offline procedure.vbs program. I think there will be less chance of mistake by this method.
my mobile is being detected perfectly by pc suite and other media, as you mentioned i can see two drives also.
Basically i am standing at the starting problem again...wtf....
Nevermind bro thanks for the help. I have already given you so much headache.:angel:

There is full-working guide for flashing and rooting by me in Development section. Also it seems you missed the Collection of ROMS and Rooting post above in General Section too.
Forget windows enabler or vbscripting and flash offline in simple steps and simply root. perfectly works for P765 and others variants too.
I am with Rooted Stock V10c on P765 India. Working superb with no issue at all since 2 weeks or more.

I followed your guide only
hello,
I am from india too and i am on 10d firmware, i tried your guide only from starting and believe me I followed every single step in your guide but actually I am getting error while updating at 3-6%....
"communication problem between device and PC"
For information I tried software update method and usual mobile on (Debugging on) methods. even tried every single usb port in my PC.
I tried atleast 20 times to restart in different modes but still it donot complete....I am really frustated by its low memory. whats the point of having a quite powerful hardware if I cannot even play games just because of low memory..

I think if its stopping at 3-6% that roughly means the flashing did not start at all upto that poing and you are getting total connect proble. Tried changing cable? Cant ruleout connection problem due to cable with weak transmission. Also a driver issue.
This worked here for everyone on P765. You may try again with proper drivers.

Did you start software upgrade mode by power off your phone and hold volume up button when plug in usb cable? You phone should show software upgrade screen.
I remember that I can flash almost other model/variant on my phone except one, which I cannot remember. If it not compatible with your phone there are error after reboot.

Rom Update - Connection Problem

I know, I know: First use the board-search and google...
I did that and I couldn't find anything useful for my issue.
I'm trying to update my HTC Prophet G4 to WM6.1...
I wanted to use SoftSPL and after executing the SPL.lnk the screen turns white as it should, but after that Windows XP doesn't recognize my phone anymore as connected.
I tried different USB-Ports, but the "ROMUpdateUtility_NV_G4.exe" keeps telling me "Error 260" which means it couldn't connect to my phone.
I'm really desperate cause I've already tried to upgrade for some days...
So if anyone knows how to fix that plz write =D English and German are okay with me

Thanks for posting, but as I already told you: I did my research...
So I already tried different FlashingTools, like ProphetTools etc.
When I SoftSPL, I get to the whitescreen but i cannot make my pc recognize the phone at my usb-port.
When I enter the 3-Colored-Screen manually it shows the usb-connectivity, but I cannot update the ROM...
There was a way (I cannot remember anymore which way I did it, cause I really tried very often) I entered the 3-Colored-Screen and there was "RUU" written in the right upper corner of the screen. But then again the connectivity doesn't work...
Also tried different usb-ports and cables...
I could say that I'm feeling like a weirdo, cause upgrading a rom seems easy and still makes my day miserable xD
//EDIT:
Didn't see the "Lazy_Tool" at the first glance, but now after trying I still get the same error...
//EDIT2:
Realized that the error-code could be useful^^ --> "Error[260]: Update Error" (Sth like that^^)
I had a similar issue. When your PC reports it cannot connect to the phone - does the phone restarts?

If u want to know if I bricked the phone then no =) I can restart it and everythings fine^^
If u meant sth else plz specify your question a bit
@ dioxda2:
Ok I'll experiment a bit^^ I'll get my new hardware soon, so maybe the error won't be a problem^^ We'll see =)

OK, rephrasing: the problem I had with my phone was that while a ROM update was running the phone would restart and I got the same error you did.
It turned out the battery was at fault, after replacing it with a new one - it works great.
If u do as dioxda2 says all should be fine. He is right in saying 260 is a connection error. That means unplugging all usb devices out of ur machine. It also means disabling all other connection software, like my raspberry program that display device screen when active sync'd. I always disable my anti virus and firewall (make sure ur not connected to internet at time).
i always ensure that the flashing tool is on the root drive, not in many folders (so place flash tool direct on ur main hard drive in its folder as uve unzipped) this itself can cuase connection errors. Ensure battery is 50% min too.
Good luck

[Q] p769 - softbricked by noob

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.
i would love some clarification, and assistance, as to what i CAN do from here. i am 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).
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
again, 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...
thanks

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

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...

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

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

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 .

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.

[Q] Xperia U rooting issues, call for help

Hey Guys,
Really hoping someone can help me out here. I've been trying to root a friend's Xperia U for the past 3 days now, without much luck!
Its on ICS, Firmware ST25a 6.1.1.B.1.10, unlocked bootloader. The two methods are Bin4ry's script and using FlashTool .For starters, USB debugging is enabled.
In both cases, the phone was undetected, even after installing loads of drivers found all over the web. After extensive reading, I came across a suggestion to enable USB tethering, and lo behold! The phone was detected!
"What's the problem then?", you ask?
Well, after following the careful instructions to restore the 'RootME' backup (on the phone), it phone reboots. When it comes back on, the screen is a mess, very dark (similar to a burnt screen) and extremely slow to respond. I read elsewhere that this is quite normal(!) and will be fixed after subsequent reboots.
The problem lies here, as I believe USB tethering is no longer ticked after the reboot, and it needs to be, doesn't it? Both Flashtool and the script wait for the phone to be detected, with no change at all. I somehow manage to navigate to 'Settings', but on trying to access tethering, it always crashes as below:
"Unfortunately settings has stopped"
Ugh.
How do I see the message when the screen is burnt out, you ask?
Pulling down the notification bar lets me see parts of the screen on its way down, and back up
Soooo...
Without USB tethering enabled, rooting does not complete, and I am left with a nearly un-useable device (until a factory reset). My internet speeds are terrible, and I am now in the process of downloading another firmware (6.1.1.b.1.54) in the hopes that it does not need USB tethering enabled to be detected by Flashtool (or Bin4ry's scripts)!
Thoughts? I want this baby rooted and CWM'ed!
Use xperia u toolkit..search in forums.eats very easy to root and do so many other things.i rooted mine using that only.

The problem lies here, as I believe USB tethering is no longer ticked after the reboot, and it needs to be, doesn't it? Both Flashtool and the script wait for the phone to be detected, with no change at all. I somehow manage to navigate to 'Settings', but on trying to access tethering, it always crashes as below:
"Unfortunately settings has stopped"
Ugh.
How do I see the message when the screen is burnt out, you ask?
Pulling down the notification bar lets me see parts of the screen on its way down, and back up
Soooo...
Without USB tethering enabled, rooting does not complete, and I am left with a nearly un-useable device (until a factory reset). My internet speeds are terrible, and I am now in the process of downloading another firmware (6.1.1.b.1.54) in the hopes that it does not need USB tethering enabled to be detected by Flashtool (or Bin4ry's scripts)!
Thoughts? I want this baby rooted and CWM'ed!

[Q] Update to 4.3 failed - Tablet wont startup anymore ?

Hi,
I have a UK Sony Xperia Tab Z, WiFi only 32G, it was running 4.1.2 stock with root. After a very long wait of sitting on the fence because of the loss of Tab UI (now sorted with phab7), I finally plucked up the courage to update my Tab Z to the latest Jelly Bean 4.3, using my MAC I ran Sony Bridge, it detected my device and offered to do the update. The whole update downloaded ok but it failed to install with an error about the update engine.
My worse nightmare ...... I'm not that familiar with advanced Android OS issues so please forgive my ignorance. first I tried the update again - multiple times in fact using different USB ports but always the same error. So then I tried running the Sony Update Service under Windows, It found the device and downloaded the update again but again it failed to install the up date (I tried both install options - SW Update only / Data Reset and Update) - I followed the on screen instructions correctly but always the same problem, again I tried different ports.
Starting to panic now ....
Looking through these forums and others for help ....
I've tried holding down the PWR & VOL_UP button for 10 seconds, and letting go, I tried it and then released the PWR button after 10 secs but keep VOL_UP held down, but no matter what i do it wont start up. Some times the SONY logo appears then fades to black after a few seconds....
I really don't understand what could have gone wrong, the device was working fine and the battery was 100% charged. I've tried the button combos with it in and out of the dock and connected by USB but still same result.
I cant believe that something that should work WITHOUT-FAIL does not work, I've always been an IOS/MAC man and the Sony Tab Z has been my one and only Android Device, I like the device for its design and lightness but this sort of catastrophic failure has been the thing thats aways put me off Android, it just should not happen - sure IOS sometimes can get corrupted but you can just about always get out of the problem in DSM mode, is there such a mode with Android & Xperia TAB Z. Can anybody help ?
Update: If I now put the Tab in the Charging Cradle, it seems to be stuck in a loop, first the charge led is orange, then after a few seconds it turns red and the backlight switches on, the SONY logo appears for a few seconds then it looks like it resets, the backlight turns off and after a few seconds it repeats the sequence ... continuously ?
Thanks in Advance
Jay

Thanks for your advice.
I tried SUS again and this time it started to install but the progress bar stopped around 30% and i got the same message, so i tried again and it bombed out after around the same amount of time so i swapped the USB cable for the one it came with (normaly used to connect the changing cradle) and it worked......Phew was really starting to think the thing was bricked. I guess this proves that all USB cables are not equal ?, strange though as i've used the same cable for a long time now with loads of other devices (camera, kindle, SD reader, label printer ..etc) and have not had any issues but it worked soon as I changed the cable .... maybe Sony cable is better screened as it is a bit thicker than the other.
Everyday a School day ....
So now I have got 4.3 stock running what is best method to get root back ?

Thank you for the link but I dont understand why I need to reflash?
Is there not a direct way to gain root?
To get root on 4.2.2 I just had to run a script and reboot
Ive read throgh those instructions and it looks like I have to install unlocked bootloader and then flash modified firmware
I thought that if boot loader is unlocked some of the Sony features no longer work?
Is there no way to gain root on stock 4.3 with locked BL?

Hi Joseph CZ, here you go:
From cmahendra's guide (FAQ: Frequently Asked Questions) http://forum.xda-developers.com/showthread.php?p=40483954
Download LG Mobile Support Tool and do the following steps:
..1. Remove the battery and the USB cable from phone.
..2. Without the battery, plug the USB cable and connect the PC to the phone with USB cable.
..3. Press and hold (VolumeUp) key and press (Power) key for 2/3 secs. You should see "S/W Upgrade" on the screen after a few seconds.
..4. Re-insert the battery in the phone.
..5. Start LG Mobile Support Tool(B2CAppSetup.exe), let it find the phone (and load drivers) and start the software update.

Hi Joseph CZ, perhaps you could try with adb via USB (from SDK tools), I'm not sure, though.
I think the easiest way is rooting and moving what you want...

you can try cmahendra sir's 2 in 1 guide or if you can, go service centre, tell them that a update (0TA) showed, AND THEN this is happening. they will.install software for you. as warranty is over, they might charge (5$ here) for software work. I did a hell lot deep **** then you, kept working 6 hours, but wasn't able to fix the phone,went service centre and now typing via same phone.
Ill try that

man service centre, like you have for Nokia, Samsung etc, you can Google LG mobile service centre around your locality,.
doesn't matter it's metro or p778,768,765,760 etc etc etc.
as your warranty is over, you have no fear of them saying warranty void, as ultimately they will charge for the software transaction.
and I know how it feels to see your phone dying on you.
JUST DONT LET THEM KNOW THAT YOU KNOW ABOUT ROOTING /BL/FASTBOOT .act like a dumb and tell them that you were trying to update your software by the wifi (software update OTA) and now this happened.
sweet talks makes way everywhere.

Hi @Aristodikos1, you have an option for installing the drivers in the LG Tool (up- left corner). If the on line tool sees your L9 that's enough, just follow the steps : Update / Tools / Upgrade recovery.
I'm not on my computer right now.
