Returning to Stock - LG Optimus L9 P760, P765, P768, P769

Hi there,
Im having some trouble trying to put my L9 back to stock firmware. I have a P768 which is running artit's CM10.1 with TWRP. Im struggling to get the phone to be recognised with the LG mobile support tool. The phone doesnt seem to connect to my pc, if i put USB debugging on, then it connects fine but the software doesnt find the phone. Can anyone help me out here, feel like im missing something obvious!
I was thinking if i restored a CWM backup of a stock rom, it would then give me LG software mode when I connect the phone and then the support tool can put the stock rom back onto the phone, right?
Thanks, donk165

Problem solved: flashed jelly cream v1 then used LG software mode on that rom, all is good

[Q] stock build for telus fascinate 3g+ (sgh-t959d)

hi there, i've searched and searched and cannot for the life of me find any stock roms or anything for the telus fascinate it probably doesn't help that I don't know what the build number is... I flashed a verizon vibrant rom quite a while ago and don't remember my methods of doing so, I've read that it's going to be a huge PITA to get it back to stock, especially because I can't seem to get it into ^&%^*% recovery mode or even get it to connect to my pc.. so any help in that regard will also be MUCH appreciated
THANK YOU in advance.. I hope!
Alright so i managed to find an all in one zip file in a tutorial post obvs i didn't look hard enough lol!
So that just leaves me with the more important predicament. I can't get my phone into recovery mode to flash with odin and my pc won't connect to the pc at all.. I read somewhere that my phone is soft-bricked???? Because of using a vibrant Rom? Any input is greatly appreciated once again
P.s can a mod change the title? Or can i? Because its slightly irrelevant to the post now

Can you link the All in One ODIN you are talking about?
I sure can here it is
http://forum.xda-developers.com/showthread.php?t=923712
coincidentally this is also the exact procedure i followed when I rooted and flashed.
so a little more information for you.
sorry about the reply taking forever i couldn't find the post on my phone and haven't had much time to sit on the computer

Says your phone model is GT i9000 so you probably flashed a gti9000 rom (Bell Vibrant / international Galaxy S).
Anyway... you need to be in "download mode" to flash via odin. I think you meant phone to pc, but were you able to connect your phone to the pc before? Do you have the correct drivers installed?
You know you're in soft-bricked if when you turn on the phone, you get a picture of a phone to pc with a ! in between. This can be fixed by a USB jig, or for some, just doing the download mode button combination while your battery is out and your usb is plugged into the computer.
What rom did you install exactly?
Yes i realise that i suppose that's what i meant but odin doesn't pick up my phone and my pc won't either. I used to be able to connect yes but now it won't I have the drivers downloaded i havent had the chance to try a different cord but this is the same cord i used to flash, so im pretty sure that's not the problem.
I guess its not soft bricked then i haven't seen anything like what you have described,
The Rom im using is called EXTRAordinary Rom or something like that ill try and find a link for you

Bump? This is a serious issue for me as my Bluetooth is not working and things are constantly force-closing...
Sent from my GT-I9000 using XDA App
If you have gotten your phone into download mode and your pc isn't recognizing it, you should; 1 - try a different pc, 2 - try a different cable or 3 - try both. Are you still able to get it into download mode?
Ughh I've tried every computer in my house, 3 laptops and one desktop...
My personal laptop is the only one it worked on previously, it now doesn't work, and I only have the original cable i did the flashing with originally, but i'll yoink a cable from work tomorrow do test that out, although I am seriously doubting it would work... my widgets have recently stopped working as well, they say "problem loading widget" I'm pretty scared by this point and feel as though my phone is sloooowly hardening into a useless brick. i'll update tomorrow, when I get a new cable.
um also, I've posted this question in a different thread but have yet to be answered, why can't I find the telus usb drivers anywhere? they don't have it on samsung's website,,, i haven't installed any drivers since the original flashing and have no clue as to where to find them... as far as I could remember it was ridiculously easy to find them last time....
Thanks in advance,

Problems with froyo, pc & ginger update

Ok my cousins ace is stuck on froyo with vodafone, locked to network.
He's got issues with power, but new battery & mine also does same thing, whenever you start phone battery its empty, but if you plug power in & start phone, then remove power battery is fully charged, so its either FW goosed or hardware on main board.
So tried to connect to pc, will not show up as samsung android device, but when mines plugged in it shows up perfectly, it sees a usb device but wont install with the correct driver, even if pointed to this, just shows as unknown device.
So my question is, how can I update it to ginger or a fresh froyo via recovery mode as it requires a zip file & all fw's are through odin.
I considered cwm, but this requires rooting yes?
So best route is to root, install cwm then install a custom fw to see if it fixes issues then install a stock rom via odin?
Ideas please & best way forward.
Thanks in advance
no, u cannot flash custom roms via cwm if u still on froyo. most custom roms need gingerbread as base, means u need to already had gingerbread installed.
and the only way to upgrade from froyo to gingerbread is by kies and odin. but because kies is highly dangerous and known to brick phones, odin is your only option.
Looks like its a warranty job then huh.
Ok so before I take this into service center, anyone else have any ideas to try, as I cant see anyother way to fix this buggered FW.

Sony Xperia S Bricked

I was using XZXperience 2 on my Sony Xperia S, and then sony companion detected that i had firmware 6.1.A.1.45 and 6.1.A.55 was available, so just to give it a try, I installed that update, but that is a failed update, it says unfortunately music player stopped working, or unfortunately xperia keyboard stopped working etc. The main problem is that my system does not recognize my XS anymore, it says USB Device Not Recognized, so I cant connect it to Flashtool or PC Companion for repair. The Sad part is that I cant even connect it in Flash Mode, I tried a hard reset by using power button and volume up buttons, but no use. I should mention that once it recognized my phone when i turned off my laptop and removed its battery too, after restarting both phone and laptop, flashtool detected that phone was connected with USB Debugging OFF, though it was on, but as a try, I unchecked USB Debugging and then checked it again, and it worked. Now my Xperia S was connected in USB debugging mode, I tried to install busybox, rooted it, and tried to install CWM recovery,flashtool said that busy box was installed and phone was rooted, but it could not install recovery and I used another tool to install recovery,which had a bat file and it installs recovery automatically. But it didnt. After restarting my phone, the same issue appeared again, My PC does not recognize my Xperia S, tried previous procedure several times, but no use. Cant even repair it as my set cant go in flash mode. What can I do? have I bricked my Xperia S? I`m in Pakistan and there is no official Sony Mobile franchise as they dont launch their flagships in Pakistan. Please help me, considering I`m used to with rooting,flashing etc. How can I connect my phone in flash mode? Thank you.
Thanx

It looks like another strike from the productors. They usually send you malicious updates which cause your device to stop working. This only happens to rooted phones which run custom roms. And since the rooted users only flash their roms in zip format, sending an OTA update patch(designed for stock rom) to a custom rom can only lead to a malfunction. I am not sure whether or not sony did that on purpose, but the truth is that after installing a custom rom NEVER do OTA updates(unless they are from the rom's developer).
If you want an update check your rom's thread and there may be new flashable versions.
As for making your device work, the only thing you can do is to call technical support or go to a phone service(in my country they are called gsm services, and they fix mostly everything, both hardware and software. Some even claim to be able to fix water damage) but given that your warranty is voided, you will have to pay for the reparations. I guess they will only do a re-soft(delete everything, and install the stock version, you may lose your root, i am not sure here.)
I hope this helps, this is how we fix things like this in our country, so it will work in your case too, hopefully.

Thanx for your advice. I was almost hopeless, but after spending continous 16 hours, I`m now able to get a solution. I got another data cable, removed battery of my laptop, and made a hard reset to my phone, and after 10-15 min I tried again, and Thanx GOD, it detected my phone, so I hurriedly start repair my phone option and connected my phone in flash mode which was successful and that was not less than a miracle, because i`ve been repeating same procedure and it was not working, this time luckily it worked, now i`m using stock rom with firmware 6.1.A.2.55. Now I would either wait for official Sony JB Update or I would flash a custom ROM XZXperience 2, which I found awsome, as it had no bugs, and it improved battery and sound quality was significantly imrpove + Bravia Engine 2 with improved graphics. I would ask users to not to give up hope, there is always a solution to every problem.

Get a new data cable, fortunately almost all phone now a days have same data cable, u can try data cable of some HTC, Samsung, Blackberry or even Iphone`s data cable. Secondly, u must turn off your PC, and remove its power source, if it is laptop then also remove its battery. Then after 5-10 minutes, turn on your PC and connect the phone. Also try installing drivers, which u can by using PC Companion. You can also install drivers by using FlashTool. Download it and extract it, then go to the installation folder and look for folder "Drivers" open it and u will see an exe file. Just run it and select Xperia S and follow the instructions.
maybe not new usb cable sometimes usb port is broken
Hey, I had the same problem a few time ago, you can try to restore with flashtool, if you can still get in to flash mode

Since you CAN'T use custom kernels with locked bootloader (and so, no cm10)
You only need to flash stock rom and then relocking your bootloader

I am also having the same problem
I have sony Xperia S. I updated to the latest stock firmware version(6.2.B.1.96). after this update I rooted my phone using old kernel .200 and update the firmware's kernel again to stock after that I locked the boot loader again. Now I can't use memory stick that I used to use before with OTG cable. And now, if I am trying to enter flash mode by pressing volume down key, the led turn green for a while only about 10 sec while this was happening, my pc say that USB device not recognized. So, now I can't use flashtool or sony update service tool(SUS) as well.
Now I am using stock .96 rom with no error but I want to install CWM and also want to unlock boot loader again to test some custom roms.
Pls help me what I have to do and what should. I am now in Delhi.

To unlock the bootloader you need to enter fastboot (blue led) with vol+ during the boot, not vol-
Or you can also reboot the phone from adb with
adb reboot bootloader
If phone still doesn't stick to fastboot, it has to be a driver problem
There are lots of guide on the procedure (which is really hard on windows 8)

I can access fastboot mode but I can't access flash mode. pc said that device not recognized. so, I think it is device error.

Bricked my phone - please help!
Hi,
I think I bricked my Xperia S. I already had cyanogen 10 on my phone, so I thought I could just flash the new Cyanogen 11 4.4.2 ROM and GAPPS over top. I followed the instructions but I skipped the Fastboot step. I cleared the cache and system and then went ahead with the ROM and GAPPS. Once the ROM and GAPPS were installed, I selected "Reboot" and the phone turned off and now it won't boot at all. If I hold the power button, I get a faint vibration and if I hold the up volume and power I get the 3 vibration sequence but no boot. Please help!

QmobZ10/Wiko Fever Bricked Only Led Light ON when usb plug in ... HELP PLS

Hello Guys !
I have Qmobile Z10 which is same as Micromax 5 e481 ,Wiko Fever & Blu Life One X
I have flashed Wiko Fever Stock Rom on my Qmob Z10 which was done through official wiko software and it worked flawlessly , then i decided after few days to go back to previous offical Qmob Z10 Rom , i found some several same links , but it was supposed to be flashed via sp flash tool cause its MTK 6753 device ... So i downloaded that and load scatter file and everything and i flashed it and it flashed 100% successfully but after it was completed i unplug the usb cable and try to on my device but nothing appears at all (Hard Bricked i guess) but still i get my device led light on when i plug usb cable with it and it is recognized by computer and sp flash tool and i can reflash it again , but im unable to find any solution that why official stock rom made it bricked
If any moderators or any one share their opinion or way of help that would be really appreciated
Charge the phone for a couple minutes then reflash the stock using spflash tools. After turn it on while charging and/or try while unplugged.
This happened to my blu when I restored to a previous backup using twrp 3.0

Try doing a manual format in the format tab of spflash, then Downloading the firmware to your phone. See if that works. If that doesn't work, try another similar phones firmware.
My Blu life one x did the same thing and I flashed it with the wiko fever firmware, then manually formatted and downloaded the Blu firmware to it and it finally worked.
Hope it works out for you.
PS- Never flash the bootloader
