[Q] Sorry, but i need help!! :( - LG Optimus Black

Ok, i was looking for flashing a kernel on an Lg Optimus black (i do not own the device), but i really can't fins anything... Can someone be gentle with me and explain how to plug the device in fastboot mode and flash the kernel.... I work with the Xperia devices and there the life is easier xD. So the questions are:
1)Where can i find the drivers USB?
2)How to plug the device in fastboot mode??
3)How to unlock bootloader
and i think that when i achived those passages i know how to go on... maybe like this:
1- Enter in the folder with fastboot's files inside
2- press shift + right-click and then select open command prompt here
3- Type: fastboot flash boot boot.img
am i wrong?? Please tell all the things that can be helpfull, but only for me, maybe for others noobs like me that dosen't know anything about this device this post i think the can be very helpfull for lots of people. :laugh:

but i can't find it out!!! plz if someone else have to answer like this plz stay away... Man please if it was a joke this wasn't funny i really don't know how to flash a new f*****g kernel, to flash cm10.1 nightly

The Optimus Black doesn't use fastboot. Everything is done through recovery.
Download Clockwork Mod from the Play store, use that app to flash a custom recovery.
Enter recovery by repeatedly pressing volume down at power up or use a reboot to recovery app.
To flash roms/kernels, copy to your sd card, boot into recovery, select install zip.
The bootloader is not locked, unless you have flashed the offical LG ICS rom with the smartflash tool. If you have and want to unlock it, just flash any froyo/gingerbread offical LG rom with smartflash, that will unlock.

1. Make sure you are rooted, if not, read Nooby's how-to on how to do it. It's a sticky in LGP970 section on xda.
2. Once rooted, you can install ROM Manager and flash cwm/twrp recovery from there. Give it root permissions when asked for.
3. Boot into recovery using ROM Manager or any other third-party app. Flash the .zip for the kernel you want. Make sure it is compatible with the ROM you are using.
4. Once kernel flashed, boot into the system.
Bootloader is generally unlocked unless you are running official ICS on your OB. If that is the case, don't do any of the above mentioned steps as you will end in a boot loop.
If on official ICS, use Smart Flash Tool to flash unlocked bootloader. You can follow instructions here on jockjoint's thread
Once bootloader is unlocked and you have flashed su.zip as per instructions in the previouslsy mentioned thread, boot into recovery (it's already there in the unlocked bootloader flash).
Once in there, flash a compatible kernel and ROM as per your needs/liking.

If you still need help, I wrote this guide for you and anyone else who is confused.
Now that you have unlocked the bootloader follow these steps.
1. Boot into the bootloader by pressing volume down + power.
2. Press the power button to enter fastboot.
3. Make sure that beneath the first few lines on the top of the screen it says fastboot usb highlighted in red.
4. Find a version of TWRP, WCX, or whatever recovery image you are going to use and then extract it into the folder on your computer.
5. In CMD, type this:
fastboot flash recovery "name of the file.img"
6. Press [bootloader] to go back to the main menu (without the brackets).
7. Scroll down with the volume button to recovery.
8. Boot into recovery.
If your recovery works, do this to use a custom rom.
9. Go back into the bootloader by turning your phone off and then using power + volume down.
10. Download a custom rom and open up the .zip file. Then, extract the file named boot.img and extract it into the folder on your computer.
11. Enter fastboot and type this into CMD:
fastboot flash boot boot.img
12. Go back into your recovery (following the steps above from 6-8). Mount your internal SD card and put on the file of the custom rom you wish to use onto your storage. Be sure to copy the file in .zip format, not after it has been extracted.
If your custom rom needs Google Apps, then download the correct file which should be specified in the download area of your rom's post.
13. Go back into the main menu of your recovery and then choose the option to flash the file.
14. Choose the file that you have just loaded onto your storage.
15. Flash Google Apps if you need it.
16. Thank me if it worked
works like a charm:laugh:

Okay, you need to first make sure that your bootloader is unlocked, to check this enable USB debugging, go to your adb directory and open a CMD and run adb reboot oem-unlock
If it returns with 'good to go' or something similar then it's unlocked, if not, follow unlocking procedures.
Second you need to download CM, and CWM.img place the cwm image in your fastboot directory and run fastboot flash recovery 'name of file'.img. once that is done do a bat pull and when you put it back in turn on and hold the volume up key. This will boot you to recovery.
Make a back up.
then you need to wipe data/factory reset, wipe cache partition, go to advanced>wipe dalvik cache. Go to mounts and wipe /system
Go to install zip on the main page and locate either on the internal storage or the external storage the zip of CM and install it.
Reboot and wait up to 4-5Minutes for first boot, once booted go to your browser and download the Gapps zip and flash in the same way as you did the Rom without wiping anything. If you would like to use a custom kernel download the correct kernel for your android version and flash in the same way as gapps.
If you have any problems just search for a flashing tutorial or post your problem back in this thread rather then opening a new one.

If you aren't capable of following the current instructions then you should not be attempting to mess around with your phone.
None of it is difficult and all the information is out there - make it your responsibility to read, understand and know what to do if it goes wrong.

people is your weapon. you know how many videos are out there in youtube ? even if its an old one, it will definately help you understand the whole procedure. really it cant be any easier. u need to root the phone so you can install anything. u need to unlock the bootloader so u can change the boot image , you need to format so you have a clean phone and of course you need an os to open up again the phone. like he said it cant be any easier. take for example me. 4 months ago , i start reading and watching videos. it took me 8 days to learn the basic and understand what i have to do and took me one day to do it. 9 days overall. now ? now i can totally mess it up and bring it back to life in 5 minutes... study it a little. you cant mess with linux based os without understanding how it works.
<<EDIT>>
For example ,
Here says u have to do that to unlock.
He says for windows u need the drivers. You can search and find them. For example one place to download them is here.
How to install the drivers has nothing to do with this forum , you must know how to force the drivers in windows , but if u search u will find that too.
To unlock now is only one command in terminal. wait a few seconds and u are done.
The procedure is only one command. the hard part is not something that has to do with the android or the forum. its windows fault if its so lame that cant even recognize properly a simple usb device.

Do you have a custom recovery already installed? Which one? If you don't, remember that in order to flash a new ROM, you need to install a custom recovery.

Sure, buddy.
You need to download a custom recovery, this is the option in Android that lets you erase all content in the device and do other things. With a custom recovery you can do even more things, like install .zip archives or ROMs, erase partitions, dalvik cache, etc, etc, a lot of things.
I personally use this one: http://forum.xda-developers.com/showthread.php?t=2552622
Since you are already rooted, I think that you are familiar with fastboot. In order to flash a custom recovery, you need to do this:
1. Download the custom recovery
2. If it's in a .zip, extract the archive so you have one *.img archive.
3. Then, copy that file to the folder where you have the fastboot.exe archive.
4. Open Windows command console and change the directory to the one where you have the files.
5. Turn off your device, then press volume down key and power key. Hold until you see a black screen with white letters. Connect via USB to your computer.
6. Run the following command in the command console of Windows:
fastboot flash recovery recovery.img
Where "recovery.img" is the name of your custom recovery archive, for example, "philz_touch_6.22.7.img"
7. Wait about 6 seconds and in the console you should see something like "done", I don't remember exactly what does it says.
8. You are good to go. Turn off your device. Then press the volume up key and power button. Hold until you see the custom recovery interface.
After this point, you can flash the custom ROM of your preference.
In the Philz link above, it goes to our thread that links to the main one, from there, download the unified moto-msm8960 one labeled for xt925/xt926. Last time I checked it was more up to date than the native mb886 one (not surprising since our CM repo is gone).

Lol, i made this thread bcuz i dont know how to use fastboot + dont even know how to enter recovery.
Install this
minimal_adb_fastboot_v1.1.3_setup.exe - 2.12 MB
Then install flashtool from flashtool.net. Goto C:\flashtool\drivers and run drivers.exe
Choose Z1, flashmode and fastboot drivers.
Enable usb debugging and unknown sources on the phone.
Turn the phone off and attach it to the computer whilst holding the volume up button. Then goto the folder where you set up the fastboot, make sure you have no items selected and rightclick whilst holding the shift key. Choose open command window here.
then type
Code:
fastboot devices
you should get a result back indicating that there is an attached device and a few alphanumeric characters.
If not let me know.
If you do then carry on with this.
Extract the boot.img from the update.zip and place it in the same folder as the fastboot. Then type this if the kernel is called boot.img, if not, replace the boot.img with the name and extension of the kernel
Code:
fastboot flash boot boot.img
To enter recovery just boot the phone and press the volume up button when the phone vibrates or the LED flashes (If it does not vibrate or flash just keep pressing it until it enters recovery)
OK, will try it later today.
there is just one thing missing, what to do after flashing boot.img ?

4.4.4 Bootloader Unlock?
I have an Xperia Z C6616 (10.5.1.A.0.283) that I rooted using easy root via flashtool. However, in the service menu, it says I am unable to unlock the bootloader. Is this true? Will I be forced to flash back to 4.3 to unlock it?

If it says you cannot unlock your bootloader, then you cannot unlock it at all, regardless of which firmware version is installed.
The C6616 bootloader is permanently locked because Bell requested it be that way and there's no way (either officially or unofficially) around it, unfortunately.

Well thats incredibly frustrating. Is there any way then to flash new roms or install a recovery? Also, it might not matter, but before I updated to 4.4, it listed my model number as C6606.
Bootloader Issue
Hey guys, ran into a little issue. I flashed my phone with a stock ROM, C6603_10.3.A.0.423_Generic ES.ftf.
Figuring It'd be fine, I then proceeded to attempt to unlock my bootloader. However, this time after flashing this stock ROM, unlocking the bootloader would cause my phone to crash, resulting in having to reflash the stock rom again.
Any ideas?
Cheers.
Please help!
Hello, I need help with unlocking the bootloader for my Sony Xperia Z please. This is the first time I am doing this, so I am a extremely novice on these things. All I want is to flash the sony rom and install android 5 lollipop on my Xperia Z
I have done all the steps mentioned above but when I type the command fastboot.exe -I 0x0fce getvar version it just says waiting for device.
I don't know if my phone is even in fastboot mode. I have turned the developer mode on phone setting with USB debugging set to ON. When I connect my phone to the computer I press power and volume up for around 10 second before plugging in the USB. The phone vibrates 3 times and there is a sound in computer but nothing else happens. When I type the command adb devices, it shows no device attached.
I don't know if this is due to me not installing the drivers but I was tried to install Flashtool-drivers-1.5-20140318.exe file, the installation failed. So I went to advance startup setting and disable driver signing. It then installed. I also downloaded the fastboot package and clicked all the exe files. And my phone has its rooting status: Bootloader unlock allowed: Yes
Please help!

You're holding the wrong key combination.
Power your phone OFF first.
When the phone is off, hold volume UP only while connecting your device to your PC. Do not press the power button. The LED should light up blue when done correctly. You can then stop pressing the volume key.

Oh Thank you so much! I think I unlocked the bootloader now
So what do I need to do now to install custom ROM?
If I understood correctly, I need to flash the current Sony ROM and install different one? Then again what is root? Is unlocking bootloader rooting? Also is the information on the forum up to date? because according to it the newest firmware is 10.3.1.A.0.244/10.3.1.A.2.67. But my firmware is 10.5.1.A.0.292. Please help, I tried finding these information but can't find them.

So what do I need to do now to install custom ROM?
If I understood correctly, I need to flash the current Sony ROM and install different one? Then again what is root? Is unlocking bootloader rooting? Also is the information on the forum up to date? because according to it the newest firmware is 10.3.1.A.0.244/10.3.1.A.2.67. But my firmware is 10.5.1.A.0.292. Please help, I tried finding these information but can't find them.

In my own opinion, you shouldn't even unlock your bootloader without getting better known to the entire device and its ROMS/Kernels and etc.,
Anyway, I tink that you haven't made TA pratition backup even, and if I'm right, then you've erased your DRM keys forever without a way getting them back.
But if you have made TA partition backup, then we can proceed to explain next thing.
To flash a custom ROM, you don't have to flash newer nor older software version.
All you have to do is go to your favourite ROM thread and read the instructions very carefully, otherwise you're risking to brick/soft-brick your device.
But on different ROMs can be different flashing guides, for example, we can take "Validus" ROM:
VALIDUS
Flashing instructions are : (I'm going to quote them)
1. Make sure you have CWM installed and a working nandroid backup
2. Download the ROM.
3. Place the ROM on your SD-Card.
4.Extract boot.img included in zip and fastboot flash it via Flashtool or CMD
5. Reboot to recovery.
6. Wipe data-factory reset/cache partition/dalvik cache
7. Flash the ROM.
Optional- Flash GApps.
8. Reboot and Enjoy Validus!

So in overall, that mean at first you've to have CWM (ClockWorkMod Recovery) (but I think that it's not necessary if you would flash boot.img with it either way)
Secondly, you've to put the entire ROM in your SD Card (not in phone memory), you can include gapps as well,
Third, you need to extract the file named "boot.img" from the ROM which you've downloaded (Now i'm talking about VALIDUS and ONLY IF YOU'RE GOING TO INSTALL THIS ROM EXACTLY), but don't remove it from .rar/.zip.
After you've done everything what is written above, you can flash boot.img using the command prompt and fastboot file, which you were using to unlock your bootloader.
The command is this : fastboot flash boot boot.img
Then, write fastboot reboot and as soon as your LED will change color, push the volume up rocker and then you will be in recovery. After that, go to "Apply Update" --> "Choose from files" or sth (don't remember now), --> "Validus.zip/.rar". and optional you can flash gapps either.
And then pus the button to "Reboot now".
That's all - you've newest Validus build.
But the main point is that for example you would take Pabx rom, you'll have to do everything using CMD (fastboot)
PABX's ROM YUGA L
Look at yourself and compare everything.
Validus ROM is customized than Pabx ROM. It has more customatizations either : APPS, Control, Mods, Gesture and etc., and Pabx ROM is pure-stock L (I think).
I hope I anwered to all ur questions, if not - quote me
Thanks!

Thank you very much for your reply and yes perhaps you are right. I should not mess with my phone's software. My skill and knowledge on this is extremely limited. I think I did unlock my bootloader but I will leave it on that. My phone still runs fine for now. Unless I find some tutorial videos which I can understand, I will stay away from flashing my phone
Thanks again for help.

Well, you shouldn't be afraid of flashing stock 5.0.x, as you're not flashing custom kernels. To flash pabx's rom, you just need to connect your phone via USB to PC, whilst holding Volum +. (Phone need to be turn on). Then blue led will show up and you're ready to write commands via CMD prompt, wich you can open in sdk/platform-tools/ (or simply download ADB and fastboot drivers).
To open them, just with holding RMB click on "open command prompt here", then write this command:
fastboot devices
Click to expand...
Click to collapse
And if it will show you like CXXXXXX (or something like that, if not even first letter is C, it's alright), you're ready to go.
Then download all files needed from Pabx site (ROM and gapps). Extract both in ADB-Fastboot driver's folder (in which are fastboot.exe, adb.exe). It should be these files: userdata.img, system.img, boot.img.
And then you just simple need to flash these IMGs:
fastboot flash userdata userdata.img
fastboot flash system system.img
fastboot flash boot boot.img
Click to expand...
Click to collapse
And then just type
fastboot reboot
Click to expand...
Click to collapse
.
Your phone will reboot and will load ~ 1-3 minutes.
Well, personally I don't encourge you to do that, I'm just suggesting. It's your choice to do that or not. I just have given you all the instructions.
Hope I helped you
Hi,
I have problem unlocking bootloader on my C6603. I successfully rooted it with easyroot, made TA backup, my phone says that unlocking bootloader is allowed but whenever i tried to do this it either fails or goes to bootloop. I was investigating a bit more and found some information saying that phone has to be simlock free with some certificates(???) and s1tool gives me answer that my simlock unlock is tampered. Is it the reason why i can't unlock bootloader? If so, is there any way to unlock it anyway?
Thanks in advance.

Did you relock while on a custom rom or kernel? Try flashing a stock FTF.

How to package and flash stock roms in FTF format
I wrote that guide for the Xperia Z, but the method is identical for the Z2. You will probably have to wipe data if you're coming from a custom rom.
