i don't know how any one is getting any of this done. i've been able to root, several times, install CWM, several times, but i can not seem to figure out how to boot into the fastboot, or into the bootloader so that i can use fastboot, so that i can unlock my bootloader. is there some magical secret that every one else in the world knows, except me???
i'm running v20d. i've got fastboot and adb installed on linux (debian), and i can shell into the phone via adb, and then substitute user* as root and delete bloat ware and every thing else - but i can't figure out how to boot into bootloader... i've tried "adb reboot bootloader" and "adb reboot-bootloader" (yes, the 2nd one is valid), but both just reboot the phone, then i see the CWM flashing lights, then it continues to boot as normal - a few times i got the dead droid icon.
i can do all this http://forum.xda-developers.com/showthread.php?p=43401184 but i can't get into the danged bootloader... this can't be just me, but it seems like i'm the only one that has no clue how to get this right
bleh! thanks in advance.

LG prevents rebooting in bootloader on most phones, including this one. Entering fast boot with the script and running the command fails BC its not an official fastboot its user compiled.

i've been rooting and putting CWM onto it before i bother with the bootloader, but i wonder if you have to unlock the bootloader FIRST, because CWM or rooting wipes out some thing that's needed to get the bootloader to allow fastboot??? i dunno, just taking stabs in the dark now...

*crosses fingers* good luck, if I find more suggestions I'll let you know. For now let's hope I'm right on this.
You're not the only one. I am also unable to unlock. I agree with omgbossis21 when he mentions that LG blocked access to fastboot. I tried several key combinations but none worked.
The bootloader is on this thing, though. The hidden menu shows the status. Has anyone tried asking LG tech support how to access official fastboot? It must exist in order for the techs to recover the damn thing.

Usually phones that don't have a key combo for fastboot you can delete main system partitions and it would start in official fastboot like my LG motion. Not on this phone though

A long while back I used the HTC official unlock ( cant remember what it is called ), I installed clockword recovery (5.8.1.5) and rooted but didnt mess with my rom beyond that.
Today my daughter was playing a game and the phone suddenly rebooted (saw it happen) it reboots to recovery. I tried clearing the cache and factory reset still wouldnt boot. Decided to try a ROM to see if that would fix it (did CG ROM Jelly Bean) no change. Not really sure what my next step should be.
It does say "E:unknown misc partition fs_type "ext4"" at the bottom of the clockwork recovery page.
still working on this to no avail, not really sure what to try next. I am worried the tablet may have died proper like.
Halp please!

Sorry for the long reply, I spent a TON of time figuring out how to do all this stuff for the version of stuff I beleive I have. At any rate the problem I am consistantly encoutnering is that I cant get to hboot at all. I also cant find advice on how I might repair hboot from recovery. I do have adb access from recovery and can do adb reboot-bootloader but it just thinks for a bit and comes back to recovery. I also tried many times doing the vol-down + power button to get to hboot.
So what is the next step if you cant get to hboot?
so have you done something like
adb reboot-bootloader
fastboot flash zimage zImage
fastboot flash zimage zImage
fastboot reboot

Yes, when I do adb reboot-bootloader it just reboots into recovery again. fastboot gives the <waiting for device>. I also tried copying the rom.zip from the ruu to an sd card and then using recovery to flash to it. It starts to try then ends with "Installation Aborted".
Not sure if there is a small easy to flash to rom that I could try, even if it wouldnt have much in the way of function. Not sure if this whole thing implies my flash is partially dead or something.
Thanks

Only thing I can think of is grabbing a proper RUU executable, there might be a thread in the view dev area that links to some, plugging in your view and try running that. You'll loose root and all but it may bring it back to life

Thanks for the idea Gersto but I cant get to fastboot so I cant use an RUU (Unless there is something I dont know). I experimented a bit trying to get the errors about the misc partition and ext4 to go away but nothing I did to that stuff seemed to persist. I do have root and can access it from adb shell.
Not sure if it is the culprit but if anyone knows how to fix the problem wit my misc partition I am all earsl.
Thanks

So I got my bootloader unlocked but unfortunately during the second flashing process the up test program froze and errored out, now my phone isnt recognized in adb devices and will only go into s/w upgrade mode.
Edit: I also tried fastboot and was able to sucessfuly get into fasboot but flashing the stock x-loader and u-boot was unsucessful and fastboot just gave me the "waiting on device" message.
Edit 2: So after quite the night of running through your guide and a couple of hard ships, I have to say this a very well written guide and it would have worked the first try if I had been doing too much multitasking while in the second flash process.
Overall was easy to follow and I got through after having failed attempts with others guide before due to oem unlock command not working after waiting.
Also I highly reccomend anyone who is going to try this to at least give the other tutorials on unlocking the bootloader for the p769 a solid read through. It will make a difference in what you understand and dont.
Lots of props and I look forward to seeing what you do for our phone in the future!

So carlos it looks like i was having the same issue as you that you posted in another unlocking bootloader thread, cant get past the adb oem-unlock. It just keeps doing a normal reboot.
I saw you got it to work with the wifi connection, is that confirmed needed for every attempt?
also in your guide you have the following command: Go to the Superuser App and update the binary the normal way
I dont know what that means , could you explain that part a little better. Thanks
Help! I was using Carlos' unlocking the bootloader guide against my will, because I love stock. And turns out karma has gotten me. For some reason my recovery wasn't installing on V20B, so I flashed back to V20F, factory reset, re-rooted, installed busybox, flashed the artas recovery... And yet my recovery STILL isn't showing up. The boot animation is inverted and the touch screen is still "messed up." I have a backup on my external SD card that I can use if I somehow get recovery functional. It's just the stupid recovery won't work and I need it to work lol. Any help? Please?! By the way, I've done an emergency flash using LG Mobile Support Tool and that didn't work, so I'm still open to suggestions.
I've been very helpful to everyone who's asked me for help, I'd like for others to be the same to me. Thanks to whoever tries
go back into recovery then make a backup in tar format then reboot into recovery and check for your files.

Also, for the wonky touch screen, it would help a lot if you enabled "Show touches" in the developers options tab~

First fix the touch screen, hold up I'll send you all the info,
Another thing, I hope you already have adb debugging enabled
Wait a min, you have everything you need if you tried to unlock your device
Inside the root lelus folder is the adb
You know, if you go to link for robert busybox on your pc (and sign in) it will send it to your phone, to download
1. Go to the root lelus folder (should be on your c: drive) and open the "stuff" folder
now, hold down the shift key and right click with your mouse, you should see an option, to "open command window here"
This should open a cmd up where the adb is at.
2. Open the cwm_ts_fix_p769.zip and go into the system folder and copy the v6.bin to your external sd
3.now type
adb devices (in the command window)
you should get a number with online status. If you don't it's because adb debugging is not enabled
4. next type
adb shell
su
your phone will ask to enable it, good luck on enabling on the wonky touch screen
okay, type
cat /storage/external_SD/v6.bin > /sys/devices/virtual/input/lge_touch/firmware
note if you put it on the internal storage, type
cat /sdcard/external_SD/v6.bin > /sys/devices/virtual/input/lge_touch/firmware
this will cause the shell to freeze.
so open up a new cmd (hold shift key & and right click inside the stuff folder) and type
adb reboot
hope this helps, if you need a better guide, lol just ask, it will take me awhile though

Sounds like you made a serious error and didn't do any research before proceeding. Did you install the LG drivers prior to doing anything with the phone? If not, you have just bricked your device. L9RecoveryInstaller.apk is the ONLY way at the moment to successfully install CWM on the P769 if the bootloader is locked. I don't have all the answers myself as I'm fairly new to this device, P769, myself. There may be someone here with a little more insight as to how to fix your issue, but if you didn't install LGs drivers beforehand, I'd say your device is bricked. Sorry.
You'll need to use fastboot to flash ICS u and x. Then go into upgrade mode by holding volume up and plugging the phone to the computer. Upgrade mode should pop up and you're ready to flash any kdz using the offline flash method.

L9 P769 is a much different creature than the other P76X variants. CWM CANNOT be installed on the recovery partition unless the bootloader is unlocked. There are very few people here who have managed to unlock the bootloader on this device ( P769 ). Any attempt to modify the bootloader, boot partition, or recovery ends in "LG Security Error". As per my previous post, the only way to get CWM on this device with a locked bootloader is with the L9RecoveryInstaller.apk.

This will not work until u use fastboot to flash ICS xand u. It will not reconize the phone until this is done.

Do you have busybox installed and or do you have multiple copies of busybox installed?
If you don't have busybox, install it from the Play Store. Make sure it installs to /system/xbin.
If you have multiple copies, which I did when I had this error, use the busybox installer to uninstall all copies of busybox and then use the installer to reinstall busybox to /system/xbin.
You may need to run L9RecoveryInstaller again. It will say there is a recovery installed just reinstall anyway.
Reboot and try again.

Yes that worked!! Thanks! Looks like we can't get CM11 onto this phone yet...currently on 20h...can the bootloader be unlocked at all...?How to get rid of all tmobile bloatware?

Cm11 is available, yes some people can unlock the bootloader. Theres a few threads about removing tmobile bloatware, along with solutions to the other questions I answered. Simply search your question and you'll find a solution. THEN if you can't find the solution by searching make a thread to ask about it. Goodluck if you try unlocking the bootloader, its quite a journey!! If you can't unlock it or the process scares you out of trying search Kuma ROM. Goodluck!

Hi, I'm in a similar boat as the OP, successfully rooted the device but didn't realise I needed an unlocked bootloader to flash a recovery. Now I get Security Error.
Now, I keep seeing "ICS x and u" on this forum, and have no idea what it is. Yet people keep saying it like it's obvious.
Is this it? http://forum.xda-developers.com/showpost.php?p=44144663
If so, obviously I can't follow the steps because my phone won't boot up past the splash screen. And said phone isn't recognized by ADB at the moment, because I can only figure out how to boot it into S/W update mode.
Currently I can't even use the L9RecoveryInstaller.apk, because, again, can't boot up. Help?

You'll need to use fastboot to flash the x and u images. They are included with the tools. Search the General section.

C this doesn't work. It gets stuck at 4 percent during the sw upgrade process.:crying:
I have an LG Optimus Fuel (LG L34C) from Straightalk running Android 4.4. This phone is (as far as I know) the same as the LG Optimus Zone 2 from Verizon Prepaid.
I couldn't find a halfway decent manual for the LG L34C so I followed the LG Optimus Zone 2 Manual to enter Recovery mode. When I held the buttons on the L34C, it would boot, show the LG logo, then shut off, show the LG logo, and do it again. As long as the buttons were held in would loop.
So I downloaded the ADB and tried to do it from there.
"adb reboot recovery" brings up the classic "No Command".
"adb reboot bootloader" just reboots it.
"adb reboot download" just reboots it.
"adb reboot fastboot" just reboots it.
What the heck is going on! I'm going crazy trying to figure this out. Why can't I access any of the special menus?
Oh, and TowelRoot didn't work to root the phone either.
I tried to enter Recovery Mode on my Nexus 7 (2012) and noticed that I also get the "No Command" prompt. I was then able to hold 'Power' and press 'Volume Up' to enter Recovery mode.
I tried this, and every other imaginable button combination, on the LG Optimus Fuel and had no luck whatsoever.
Is it possible that this stuff has been disabled by LG?

Is your device activated. Straight Talk said that reset via recovery (it's in the phones manual...) would work after activated, but that seems like BS.
full user guide from LG
Okay I got the full user guide that was NOT included this is the LG Full guide. Just Click it, had to put it on 4shared as it is too large to upload as .pdf on here.
Root worked for me after I followed this guide. http://www.androidarea51.com/all-things-root/working-root-for-lg-optimus-fuel-woot/ Make sure you change the values in post #1, and remounting /system as explained in reply #1.

now that i think about it my device was bricked.... maybe this is a special recovery designed to act only when problems are detected in the boot sequence?
Well, looks like I'm in the same boat now, lol. Going against everything I've learned in the 5 years messing with Android, I had a non-thinking DOH! moment and changed the screen density. After reboot, I just have a bootlooping cheap paperweight for the time being. I can get into recovery, but there's no menu options. I am going to try to push the backed-up build.prop.
They really have this one locked down. I haven't found an OTA zip in my searches yackaro, but I'll keep an eye out for you.
root for lg fule kinda works
I got an lg fule from walmart and decided to root it(never done it befor on any thing)I tried for at least 6 hrs and tied poot z4 all kinds of apks and finely I get towelroot to work but I cant get full acces its says setuid attribute is NOT present BUT root user ownership is present. root access is NOT correctly configured for this file! what is wrong and what do I need to do? I have been using the phone for a week downloading apps from blackmarket and googls app sometimes its kinda slow but It wont let me move systems apps to sd,can delet but not movei have titanium bu supersu busybox pro force2sd esfx and rommaneger how or can I gain full root for kitkat 4.4 lg fuel?
It is possible that TracFone (StraightTalk is a subsidiary of TracFone) is using special bootloader code to lock users out of recovery mode. I know that T-Mobile did something like that with some lower-to-mid-range LG phones.

I can't (well, couldn't - I'm soft bricked right now) even boot into bootloader. To get full root, I think we need an unlocked boot loader. However, "ADB reboot bootloader" doesn't work, right now, as well as most of all the other commands.
I was able to reboot into recovery, but there wasn't any text. I'm working on getting the fuel booting again, but I haven't found anything that works yet. The hard key combo that LG describes to hard reset doesn't work. And I've tried many other hard key combinations, but nothing works so far. [emoji20]

Yes, what I meant is they might be blocking both recovery, and boot loader mode...

True. They probably are. I don't know why they would block at least hard factory reset, though. But then again, since we paid for our device (albeit only $30) seems like we could have more freedom with it. Oh well.
LG has fastboot locked out. I was browsing the LG G2 forums when I found that people are able to get to fastboot by zeroing out their 'laf' partition and forcing the phone into fastboot (because aboot can't find it) where we can then flash a custom recovery.img hopefully. I have the recovery partition extracted and replaced /sbin/recovery with CWM and repacked. I just need to get into fastboot to test it. I will get a second phone from walmart to dev with, they're only $30. if anyone has a dev phone to test it on, read on...
This is theory and hasen't been tested. We may not even be able to run custom recovery or fastboot.
If anyone wants to pick up here be sure you have fastboot and adb installed and have some dev knowledge, not for noobs like me.
backup your laf partition to an external SD card (insert a micro SD)
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/storage/external_SD/laf.img
pull laf.img to your computer as a backup and to use later in fastboot
wipe your laf partition [I AM NOT RESPONSIBLE IF YOU KILL YOUR PHONE]
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
reboot your phone and connect it to your computer.
your phone SHOULD (I have not tested this) boot into fastboot as a failsafe.
on your computer
Code:
fastboot flash laf laf.img
Code:
fastboot reboot
phone should reboot back to normal.
This will test that we can in fact get to fastboot.
STOCK laf, boot & recovery files to look at. The included repacker does not repack the images properly. I use linux tools for repacking.

Sounds like we are a little closer, however you can push a .img thru adb already I know some people that did a mako build only problem is it bricked it.

It's the new security features of kitkat. Only allows apps to access their own folders. Try SDFix (root app from play store ). I now can read, write, copy to/ from sd or system.

Some things that I noticed that were missing (besides /sbin/recovery). There is no flash_image, dump_ image, or erase_ image in /system/ bin. Usually use flash_ image in terminal or in fastboot. Don't know if these binaries are generic, or device specific (partitions). Could copy from other device, but don't know if they will work properly. Glad I'm not alone in this.

I pulled the one in the Zone since that phone is most similar to ours, However I have a feeling the key bindings won't be correct, so I may still have to compile from source. I pulled the git for TWRP but haven't made changes to it yet. Its been a busy week at work and its only monday.

Those also don't exist in the stock recovery for the Optimus Zone. It looks as if busy box was added to the Zone CWM recovery now that I have looked at it closer. Its been a WHILE (Samsung Vibrant with Team Whiskey) since I built a recovery image.

Yeah, we might only get one shot at success (before jtag ), so it's probably best to compile from our recovery and source. I used Apktool to decompile recovery (dd if =dev/ block/ mmcblk0p17 of =/cache/ testrecovery/recovery.img). Ramdisk has./ sbin/recovery. Copied that to /Sbin/ . Disappears after reboot. Haven't yet decompiled boot.img. Hoping to find "boot", and fastboot. More later.

Do you know anything about the Loki tool by Dan Rosenberg:

Have to admit that I'm not quite this educated, but that looks promising.
Edit: This is like having to root your phone twice. Lol
EDIT: Don't nuke laf yet! I dd and decompiled it (had to rename it to boot.img in Apktool). There are some interesting images (png) in res folder. I'm gonna dd aboot and abootb, and see what's there. Gotta go to work soon. Probably more tomorrow.

Thanks for all your work. Im also very interested in being able to boot into stock recovery. Mainly to be able to preform a factory reset. Do you know of an alternative method to do a factory reset at this time since booting into any recovery isnt possible ATM?
