Hi everybody! I'm new at this forum, i come from xperia x8 forum, and I have problems with custom kernels. I have a xperia Neo V, and I just cant connect the phone in fastboot mode. I'm not sure if it is properly bootloader-unlocked, as in the oficial sony's webpage it said that cdma devices cannot be unlocked (check http://unlockbootloader.sonymobile.com/), and I think that is the standard in Europe isn't it? (I'm from spain). Also, I checked the service menu and it also indicates that the bootloader cannot be unlocked.
Anyway i tried through the testpin-s1 tool method and everything seemed to work fine, i got the output with the two lowercase "r", but not the messages showing the model, software version, custom version, filesystem version and serial number, as said in vimjam's guide (check the post regarding unlock BL here: http://forum.xda-developers.com/showthread.php?t=1409269).
When I try to connect it in fastboot mode it just shows the sony ericsson logo and starts to charge, not showing any blue led. I know that this happens in locked devices, but the two lowecase "r" in s1 tool indicate that it is unlocked, so i dont understand... Can someone tell me if my phone is properly unlocked, or if custom kernels can be flashed connecting the device in flash mode (as it does work for me)? Thanks in advance
Eventhough your bootloader is now unlocked, your fastboot is still locked, you have sim-locked phone and you need to pay to unlock it.
ok, so you mean I have to sim-unlock my phone in adition to bl-unlock to connect it in fastboot mode? can this be done in wotanserver or i have to take it to some tech service?

Hi,I managed to unlock my bootloader using msm7227_semc.cmd method.However when I tried to enter fastboot I couldnt
as my sim was locked.I paid for unlock via S1 tool and now have an unloked phone.However when I identify the phone to check
the status of the bootloader I only get one r "Look For Line RUNNING S1_EROM VER "r8A029" but the loader version has a
R .Is my bootloader still unlocked? I have tried getting into fastboot mode but nothing seems to happen.Can you please guide me?
Thanks for reading .Your reply is much appreciated.
Hello everyone,i have a big problem.
The first time i've tried to unlock the bootloader (following the guide of this section) i've check with s1Tool,and everithing whas ok.Then i started the flashtool end click to plugin and i've run the bl unlock.The ploblem is that after that action flashtool looks like stuck (because nothing happened) and i close flashtool and unplug the device.The device now works ok,but the option on the flashtool for unlock the bootloader just disappear,i can't unlock the bl anymore .I've checked if the bl was unlocked with s1Tool and it says it is locked.
What can i do now to unlock the bl?

I think something might have messed up with kernel or rom.
If you want to unlock I suggest you to go to stock 2.1 or 2.3.3 and the bl unlock plugin should appear again.
Thanks man

First flash the European open V20B kdz and make sure you have a signal (you can make calls and etc.).
Next leave your phone on for 30 mins. and then try to unlock
Note: if you have already tried 30 mins and it didn't work, leave it on longer before trying (eg try the unlock after 8 hours)
good luck
Hello !! I already tried to flash a v20b KDZ under section "European Open" , but unfortunately when I go to see the in the phone information appears only " P760v20b " without " EU-XX " acronym . I try to flash several v20b KDZ with the same result...Can we help me to find a valid v20B KDZ ?? Thanks
So you are saying you can't make calls?

Hello man ! I just tray to flash this KDZ and wait about 23-26 hours but the phone just reboots normally...So what can i do ???

I just unlock my P768f boot loader yesterday. Europe Open Link for download V20B is forbidden now, I used V20C and it work fine. Not sure why your phone only reboot to normal mode.
I just follow this thread for P768 http://forum.xda-developers.com/showthread.php?t=2313794. It work at a first try. I'm already on stock JB rom (P768f) for about 2 weeks before unlock bootloader.
Just want to confirm that Europe Open V20C also bootloader unlockable.
Hello artit , then you tried to unlock your bootloader on v20c without reboot the system after flash for 2 weeks ?? So , yesterday i flash v20b KDZ , what do you suggest I wait ? It's possible that my bootloader is corrupt ?

I don't think your bootloader is corrupt. For me, my JB P768f came out about 2 week ago but any P768 is not bootloader unlockable (adb reboot oem-unlock just normal reboot phone). So if P768 user want to unlock their bootloader they must flash P760 V20B rom, as I did.
If you want to try again please flash Europe Open V20C, download link from http://csmgdl.lgmobile.com/swdata/WDLSW/LGP760/ANEUWH/V20c_00/V20C_00.kdz
After flash it reboot your phone, enable usb debug mode and wait about an hour (I also not sure what this does but many people said you must wait) then connect your phone in command prompt try "adb reboot oem-unlock" again.
Thank you so much then I'll try to wait a few hours , if doesn t work again is possible to replace my locked BL with your just unlocked ?? So I should have full guarantee of success.

You are not turning your phone off at all after you flash the kdz right? You are not suppose to turn off the phone. Not sure if this will help, but one person reported success by leaving his phone connected to the charger for hours before it finally worked for him.

Hi guys,
I had been passive all this years in this forum.. many thanks to all contributors in this forum.. which had helped me a lot to root, unlock my bootloader, custom ROM, etc to my various phones, sony xperia, samsung, asus padphone, etc
now I guess it is my turn to contribute.
this L9 P768 of mine to me is the best phone I have so far, cheap, light, powerful enough to my need, battery is not so good though eventhough it is higher capacity compare to other phone in same range but hey.. it is removeable battery !!
last 2-3 months I was happy with STOCK ROM, but 2 days back I want something new, I want custom ROM, especially now someone have released custom Android 4.3
without any research, I applied CUSTOM ROM, and stuck in security error, but after reading I realized this phone is much more powerful than I thought..
I think this phone is UNBRICKABLE
cut story short.. i was able to bring back my phone alive using fastboot mode and now running stock europe open V20C (thank you for the mirror contributor.. and f*ck you LG, I kept getting permission denied and half finished download)
cut story short again... I followed various threads, and stuck in command "adb reboot oem-unlock" my phone was rebooted without getting into bootloader unlock confimation / warning screen
I was using windows xp (with all drivers installed properly, fastboot, adb, etc)
I was frustated like some few of you here that had been trying to unlock bootloader (some even tried for months..)
finally few minutes back, I got my breakthrough, I tried using my "working" laptop that has linux installed and issue command
adb reboot oem-unlock
and phone was rebooted and this time I get the confirmation / warning bootloader unlock screen !
hurray !
so to those who stuck., maybe you should try adb for linux.. here is the version that I have
[[email protected] ~]$ adb version
Android Debug Bridge version 1.0.31
hidden menu is showing my bootloader unlock
Despite all efforts I can't unlock bootloader on my p760. After sending adb reboot oem-unlock command the phone reboots normally. I tried almost all the ideas I've found on xda - flashed different versions of v20b, v20c, (europe open and country-specific) even tried v20a india for p765 - no luck, drivers are installed ok, i can enter fastboot mode and send commands (reflashed JB xloader an uboot), i rooted the phone and tried to unlock bootloader via terminal emulator - still simple reboot. As described on the threads I waited 30 mins, 1 hr, even 8 hrs before sending adb reboot oem-unlock - no effect
I'm really out of ideas :crying: Maybe my bootloader is permanently locked? Is there a way to find it out?
Since it's possible to enter fastboot is there any other way to unlock the phone or install the custom rom with locked bl?

Try flashing ics kdz, do a factory reset, flash jb europe open see if you can unlock it
I downgraded to v10a ics -> factory reset -> hard reset (to be sure -> flashed v20b europe open .... still oem-unlock results in regular reboot...
I have succeeded after a factory reset and sleeping for one night. You may try to flash EU open v20c and wait with data connected.
I tried that already ... the phone sleeped overnight on v20b and v20c and after i tried to send oem-unlock... nothing happened.
I don't know if it's proper behaviour- after sending adb reboot oem-unlock in the device manager appears TI Board/OMAP4430 only for 1 second and phone reboots normally (just like connecting the phone to usb without battery but TI Board apears only once)
After flashing 10a and before hard reset should I also flash ICS xloader and uboot or do they come with the 10g?
I'm with same problem, but my model is p768. Im still trying to find a solution to unlock bootloader/CWM/Root
I have P769. The same thing, "adb reboot oem-unlock" just reboot the phone, without anything else.
Edit: a few more tries and now I'm unlocked.

The x-loader is not found in the kdz, but the u-boot is.
Try flashing the u boot for ice in fastboot, then flash the 20b kdz.
If this didn't work, reflash the 20b kdz, but when it starts to boot up, turn it off and flash the u-boot from 20b in fastboot and try.
maybe the u-boot is not getting over written. It's easy for a p769 model owner to tell if they are on the 20b u-boot (inverted lg logo), but not for the other models.

You do have the inverted lg logo at boot, right?
You might want to try what I did.
When I was flashing the 20b kdz, I swapped the 11th bin (to root) and the p760.fls (radio file).
I extracted the 20d kdz and renamed the p769.fls to p760.fls
I didn't get root (something went wrong) but I had a network signal and could make calls.
I did make/received a couple of calls while on the 20b.
I think I waited like 4 to 5 hours before trying to unlock.

Same problem there on my P760
Tried some differents kdz, 20B from my default carrier (SFR), 20B europe open & 20H Europe Open,
With this method http://forum.xda-developers.com/showthread.php?t=2189646, This one too http://forum.xda-developers.com/showthread.php?t=2190326
Actually Rooted & With Artas' recovery 1.5
For me the first few times I try "adb reboot oem-unlock" the phone just reboot. I don't know what to do at first. Worse I have P769 and with the P760 rom on it, the phone is not usable. Then I just leave the phone there and do my own things for a few hours. When I come back, I thought I should try one more time before giving up, it all works out. Maybe I didn't wait long enough with my previous attempt. Anyway I'm done and looking back it was difficult (with my P769 this is true).

Do you think it makes a difference if I root and flash the new radio with cwm, compared to your way where you just replace radio the file?
Also is the radio file exactly named p769.fls and is it in the folder where we replace the 11th bin? Thank you
Same Issue but solved
maybe the 30 minute time is just a rough estimate. I flashed my p765 with p760 v20h and did a hard-reset(because of "com.android.phone stop" issue) and then waited for about 20 minutes with SIM and wifi on, until I turn on the mobile network switch. Then after exactlly 30 minutes I tried but failed. I googled and found this thread. After that I made a second try and worked.
So maybe just remember: 1.insert SIM 2.turn both wifi and mobile network on (not sure which matters) 3.Be patient
it may be that those who are succeeding have a different firmware / ROM version, and / or, their ROM is from a different carrier. i have CWM installed, i'm rooted, and i still cant get into the bootloader to get fastboot to unlock it, nor does this adb oem-unlock method work. fwiw, i'm using v20d TMO USA. i'll post back if i ever figure out how to get the damned fastboot to work...

We have been looking into this a lot. I recommend do try to unlock without know your stuff, you may permanently lock your device.
How about we meet up Tuesday, I'll show you how it's all done. Name the place, I'm not afraid to drive to the Northside, lol.

I think you can flash P760 rom on ypu phone. As I know only P760 - Europe Open - V20B or V20C can unlock bootloader. I you want to unlock your phone bootloader your must flash it. Their're some people that follow that thread but cannot unlock bootloader. I don't know why. For me it's work at first attempt.
For your problem, please try
- Turn on your phone, connect usb cable, select LG software mode
- In offline flash program select "DIAG" in Phonemode instead of "Emergency" then follow normal offline flash step.
- Your phone should reboot to S/W mode automatically.
After reboot their may be some software error message, you can ignore it. Some thread said that you should wait for about 30 minutes and have your sim and wifi on may make unlock bootloader success. Please give it a try.

I try this too, but without glory
But, i try to put a CWM Backup of the V20B Europe Open, and works on my phone!!!!
At first time i try to unlock the bootloader without succes, but i try a second time However, in my first try on v20B, my computer detect the OMP44...blabla,
Edit: 2 try fails too
@artit i have question, It is possible to find a better method of unlocking as unlocking via fastboot like XPERIA phones?
I was talking with a colleague Argentine was one of the first to buy the P778g just went to the Argentine market, and apparently could safely install the "v20B Open Europe" like any other ROM it existed, but after you break the screen and it changes to a other "identical" phone, the same thing has happened to his.
There may be a possibility that the method is removed to unlock the bootloader and install any ROM in our P778g?

There is no new unlock bootloader for now. I notice that a lot of people have problem unlock their L9 bootloader. May be there is new way to unlock it in near future. Just wait to see it happen, some dev is working on it.
