How to repair ACRO S????????????
[Sony Xperia S, Acro S, Ion] Terralolol:
What ROM are you trying to install ? And why don't you just flash a stable rom for a while so you can backup your data ?
[Sony Xperia S, Acro S, Ion] ItBankRock:
I can't lol, phone's totally dead. PC can't detect it.
[Sony Xperia S, Acro S, Ion] Terralolol:
You can try using an sd card reader to copy your zip files and install them using CWM. lol

Hi my friend

i have the same problem with my acro s after 2months iss still dead and unfortunetly no box till now support this kind of boot repair.

But i decide to change the security chip on main board and i hope it work but with much more money.

Or may be you can find a fine main board and change it with yours.

But if you find some other ways or boxes that support lt26w plz inform me. Thanks

I am having issues with the casual install. I have tried the latest builds but I couldnt get them to connect. Any help would be great. It pretty much errors out without doing anything after the Heimdall script. It appears to be rooted but I dont know what all is supposed to be done when Heimdall runs. Any help would be great. New user to this sight, I'm a noob to this but not electronics and programming.
[Verizon Samsung Galaxy Note II] BoostedB18C:
Make sure you have all anti virus/security software disabled including Microsoft Security essentials/windows defender. That and driver problems are the two main culprits for issues using CASUAL.

Once you have done that, reopen CASUAL and try it again. If it fails, post your paste bin log link. Don't paste your log here, just the link. Without the log its difficult to see what's going on

Hi guys I'm JulioRivz and i've a big question. Well, i'm a begginer in the mobile flashing

My question are: Can I install MIUI from this post on my Xperia Miro with locked bootloader?.

If yes, How?

I'm very noob, Please give me the instructions to do this.

Sorry for my bad english.

1.First u need to unlock bootloader

Check bootloader status,dial from your phone to check status :

*#*#7378423#*#*

service info --> configuration.If its allowed,go to sony official site and do the unlock bootloader procedure.

2. After unlocking bootloader u must root ur phone.Do the update stock sw version to 11.0.A.5.8.After that go to unlockroot.com and dwn app.Usb debugging enable and start app.EDIT:after rooting google clockworkmode recovery and flash it via cmd

3. Find and download MIUi rom,flash boot.img with cmd.Transfer rom zip file and flash it via CWM.

4. Wait after that set up ur phone and enjoy :D

Guys Guys I found out that you can unlock bootloader on v20f OMG OMG OMG OMG OMG OMG OMG!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I WILL BE POSTING BACK,,,, :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :laugh: :cool: :cool: :cool:

After Reading Some More It says you will lose all your data.. mmmmm gunna check something out

Part 1 Is only for people who has not unlocked bootloader Part 2 is for people who have unlocked bootloader and Part 3 Is For Everyone

Oh and Sorry for the cruddy tutorial will update it tomorrow its 3:24 am in Cali and i want to go to Sleep :p

Part 1

(Update) Well Its Official we have an unlocked bootloader on the P769 i attached a picture sorry its kinda blury i had to take it with my sisters ipod...

Ok well what you have to do dont worry its really easy

1) Download V20F kdz

2) Flash That kdz (dont worry about root well get that later....)

3) After it Boots Make sure you have signal to network (doesnt matter if it has service or not i havent paid mine yet and it unlocked)

4) Connect Phone To Computer and make sure you have USB Debugging on and then run the Following Command

"adb reboot oem-unlock"

after you run that command your phone should reboot i do not know why but there is no prompt like the p760 (if you want to confirm you have it unlocked do the following 1)turn off phone then hold volume up and connect usb from computer and you should get S/W update and at the top left Bootloader Status: Unlocked)

and there you have official unlocked

Part 2

ok now for those of you who did it the hard way and unlocked before i recommend you take this unlock but up to you first what you wan to do is

Make sure you have this installed "http://xdaforums.com/showthread.php?t=2119090" and setup

then download this

Lelus Fastboot Script : "http://xdaforums.com/showthread.php?t=2292828'

and then choose the one that says P769 ICS U and X Boot choose that then it will tell you do the battery thing then it will flash and now you have original X and U Boot Now you can flash the kdz and do the unlock make sure you do this first!!!

Part 3

Now to flash a recovery and flash root

Make sure you have it on your sd card there is different ones link are scattered so ill get them in a while

Install this http://xdaforums.com/showthread.php?t=2292828 then start fastboot and flash a recovery image to your phone

then make sure you have the superuser zip on your sdcard then boot to recovery and flash the zip after you flash it now reboot and enjoy you have unlocked bootloader with root and cwm now just flash another rom and there Cheers :cool:

[LG Optimus L9 P760, P765, P768, P769] heero884:
I tried the ADB command and the device rebooted. When I went into software update mode it did not mention anything about the bootloader being unlocked. I'm going to try again in 30 minutes as I had just put in the SIM card prior to attempting to unlock. Not sure if it makes a difference but the SIM card does not have active service and I flashed the 20D KDZ before doing the OTA update to 20F.

EDIT: Waited 2 hours and tried to unlock again, no dice. I guess I'll wait for further instructions.

I know this is a noob question, but where's the KDZ at? It isn't in cmahendra's repository and I really want to unlock my bootloader tonight. BTW, I'm not new. Well technically yes, but I've been lurking these forums since late January. (: So um, yeah. I need the KDZ and such. I'm already on P769F but I got it through OTA... I went into Terminal Emulator and I thought I had something, I went "su" and then "reboot oem-unlock" and it would unlock, but my phone didn't show the confirmation in S/W update mode. I'm using artas locked bootloader recovery if that means anything. Wait, actually I'm going to try something.. I might have just answered my plethora of questions. Sorry for the useless post xD

I got the tmobile lg p769 on wind mobile v21b. I just did the reboot oem-unlock through terminal. Then powered off phone and plugged in sw upgrade. And says bootloader status unlocked. It was backwards because mines been unlocked for a while. But maybe u could use the v21b cwm backup and do the unlock. I stayed on the wind rom for move apps to sd is built in. I get the same 4g coverage from tmobile. Just changed the apns.config.xml with tmobiles v20f and set up apns manully. The same tweaks work on the wind version as the others. Oh theres a telepony.xml u need to replace as well. Just thought everyone should know how much of an asset wind 21b can be no matter what carrier u got.
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Type su in terminal then press enter. Then type unlock command. It rebooted but I'm not near a PC to confirm (20f via cwm update).

The MetroPCS ROM has move to SD & WiFi calling ;) checkout my thread in the general section.

Hey [MENTION=4730658]carloswii5[/MENTION] we need someone with a locked boatload to confirm if this works. For all I know, I could have just replaced the u-boot. Inside the hidden menu, my boot loader shows locked, but it isn't. The S/W shows unlocked and I'm back on CM. Thanks anyways though, I now have a normal u-boot :thumbup:
[LG Optimus L9 P760, P765, P768, P769] leolawliet:
Can't we just technically flash the u and x boot images for V20f for P679's that are already unlocked with the P760 method? And then open the terminal emulator and run:

su

reboot oem-unlock

I figured that sounds much easier for anyone already rooted and unlocked on P769. Just a thought :3
[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Should work fine from the ota update or even cwm update. Looking at the update pushes a libunlock. DLL file to the system along with 2 other files. Likely that these files and the u image is all we ever needed.

[LG Optimus L9 P760, P765, P768, P769] omgbossis21:
Cwm upgrade should unlock as well. Just hook your phone up to USB cable, navigate to your directory that contains adb and type adb devices to confirm your phone is recognized. Make sure USB debugging is enabled if not. Then type adb reboot OEM-unlock. Phone should reboot to a screen asking you to press a volume button to confirm unlock. It should also say your data will be wiped if you unlock. Same steps as euro unlock without the flashing really.

I got pushed to V20F today, I hate the farking bloat LG!!!! (I'm used to good ole Nexus yummyness) So I rooted earlier this evening before I saw this thread. I did the ADB command but never saw the "Bootloader Status: Unlocked" message. So I'm now flashing the V20F KDZ and will see if that helps me. Fingers crossed.

Warning, over 500meg of crap and several programs to DL. Takes about 30-45min from start to finish though and I've never flashed a KDZ before.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
Lol, (sorry), yes. Once unlocked you can't lock it back. You might think you locked it but it isn't. A cwm doesn't restore/backup the u-boot partition.

Not working on my end. Just flashed 20F from 20D and nothing. Ran the command through adb and the terminal. Both commands just give an empty reboot.
[LG Optimus L9 P760, P765, P768, P769] NERVEVA01:
Just checked using the software update mode, and it did not say unlocked on the upper left hand corner. the only thing I forgot to mention is that I do have the phone rooted, I do not know if that would have an effect on unlocking the bootloader. also the phone did reboot when I entered adb reboot oem-unlock. any ideas?
[LG Optimus L9 P760, P765, P768, P769] carloswii5:
Guys this is useless for now because when you run it, it doesn't give the unlock prompt so it doesn't enable flashing a recovery in the recovery partition and I'm not sure why it doesn't give the prompt I've been analysing v20f u boot to see if there's something I can change so it will show I'm currently working on that...
[LG Optimus L9 P760, P765, P768, P769] kuma82:
What if they just flashed the u-boot from 20B after a fresh install of 20f, maybe it might work, lol. But then again I doubt it. I think the only reason, why it works for us (people that unlocked by flashing 20B) is because our fuse is blown. They did make some changes to the u-boot though.

Well good luck.

So how is that Ubuntu Touch going?
[LG Optimus L9 P760, P765, P768, P769] heero884:
How did you do it? I figured 20F was missing something so I tried flashing the European P760 20B ROM. I was able to unlock the bootloader in 30 minutes (I couldn't do it on P769 20F even after waiting 30 min and 2 hours.) I then proceeded to fix the touchscreen and restored the P769 ICS x-loader and u-boot. I then flashed the P769 20F ROM once again.. waited 30 minutes and tried unlocking the bootloader with no luck.

Are you on 20F with a unlocked bootloader? If so how did you update to 20F while keeping it?
[LG Optimus L9 P760, P765, P768, P769] carloswii5:
It was going great until my Ubuntu stopped working and I could not fix it and I lost all my information because I had to install a fresh new copy of ubuntu but then since I at the time only have this computer I need windows so I flashed back to windows and that's what I'm currently running....
[LG Optimus L9 P760, P765, P768, P769] Tablechair:
No unlock prompt for me(I unlocked bootloader previously). It does now say boot loader unlocked in software upgrade mode. Can also boot into custom recovery.

Flashed the 20F KDZ one more time and was able to get the bootloader unlocked. Now to get CWM back on there..
[LG Optimus L9 P760, P765, P768, P769] geeshiet:
Possibly using the ota root keeper? Or he must've flashed it? I think idk. [MENTION=4730658]carloswii5[/MENTION] And just to clarify... This method is useless as of now since you realized there are some errors throughout the process?...
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Was your bootloader previous unlocked by flashing the Euro Kdz, or you just unlocked it for the first time with the T-Mobile version?
[LG Optimus L9 P760, P765, P768, P769] heero884:
OTA Root Kepper is only for keeping your phone rooted when you do OTA updates. I attempted unlocking the bootloader enough times to believe 20F alone isn't sufficient. You need to flash the European KDZ and unlock that way first. After that your bootloader is unlockable when you flash 20F.

Prior to today I never unlocked the bootloader. I tried unlocking it with 20F like a dozen times.. finally gave up and unlocked it using the European KDZ. I then upgraded to the T-Mobile 20F and I was able to redo my unlock right away.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
So you temporally locked it back. Did you have any issues with the touch screen, and is your u-boot inverted (LG logo at boot)
[LG Optimus L9 P760, P765, P768, P769] heero884:
Somewhere along the line while I was in the process of moving back to 20F from European 20B the bootloader locked back on me. Maybe the next person that decides to unlock via European 20B before moving back up to 20F can document it better than I. I was in a flashing frenzy trying to get everything working.

Right now my boot screen is not inverted and the bootloader is showing unlocked on the software update screen.

[LG Optimus L9 P760, P765, P768, P769] captaincrook:
Pretty sure this would only be working who people who have unlocked the bootloader before (inverted boot splash). Can anyone else verify this? I have never unlocked my bootloader and thus, 20F oem-unlock does not work.

Looking at the NV partition its just a binary file. If we can use this code to determine where In the NV partition the flag is located we can write a module/script to clear the flag leaving the phone ready for the unlock command. There is very little data in the NV partition.
