[MENTION=5817393]dlipford370[/MENTION] You are right, my english is not so good, that's why the tutorial is not very clear.

Anyway the goal was to get fastboot access (when I wrote this, we weren't able to unlock bootloader), not to unbrick or whatever. If you want fastboot access you should know what you are doing and what you can do. Cheers.

I'm crossposting from cmahendra's post http://xdaforums.com/showthread.php?t=2085344 on how to unbrick LG phones.

My problem:

P760 European version, deeply bricked. By deeply I mean no screen at all, no reaction from any keypress or usual combination for SW mode.

Happened in CM 10.1.3, suddenly CM rotating logo, not possible to poweroff. After waiting for 2 hours, I took the battery off and I never got the phone back or even the screen or led keys.

The only thing still working in the phone is the omap interface and some fastboot commands after some bin files are injected with a usbboot command.

Hence my message here:

The bin and 2nd files sent with the usbboot.exe commands are for other phones such as P940, su760 or others... but never the P760.

I was wondering if that would change anything, apart from the model name when sending a "fastboot getvar product"

I ask because fastboot oem format returns FAILED

Also, impossible to send images/bins, no remote partition.

The "fastboot boot recovery.img" or the same with boot.img (with respectively the right boot or recovery for the P760) tells me all goes well for the transfer and reboot command... but the phone does not come back to life.

If you have any input or any way to tell for sure the phone is dead... thanks for helping!
[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
What commands are you using to flash images with fastboot? My phone was like that when I messed with u-boot, it's strange that it happened to you after remiving the battery..

Inviato dal mio LG-P760 con Tapatalk 4
[LG Optimus L9 P760, P765, P768, P769] David7578:
The command that works in all the scripts I use looks like:

usbboot.exe p940-aboot.2nd p940-u-boot_fastboot.bin

You first plug the phone without battery for omap boot, then put the battery in after that command worked.

Usually, the other commands are for flashing the x-loader and u-boot for the P760, but those command fail with "no remote partition" error

But deleting those last commands in the script, or waiting for their completion (and errors), the phone replies to fastboot commands.

Here's what I've been able to get:

fastboot getvar version
version: 0.5

fastboot getvar version-bootloader
version-bootloader:

fastboot getvar version-baseband
version-baseband:

fastboot getvar product
product: LG P2

fastboot getvar serialno
serialno: 09147XXXXXXXXX

fastboot getvar secure
secure: HS

the product name changes depending on the PXXX used with usbboot, but there are no useful fastcommands that work.

That's why I was wondering if there are images I could use with usbboot that are made for the P760

Thanks
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
If your bootloader is already unlocked, then you shouldn't need to use usbboot.exe to push fastboot to the device. Fastboot should be permanently installed. In fact, it's installed on my P769, but because my bootloader is locked I have no access to it therefore I need to use usbboot.exe to push and boot fastboot on my device.

Try fastboot flash recovery recovery.img instead of fastboot boot recovery.img .
[LG Optimus L9 P760, P765, P768, P769] kuma82:
You might be onto something. I never checked out the source for the 940 u-boot. We might be able to find some good clues.
[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
Don't delere any line from the script, you have to choose Prada 3.0 to get fastboot access.

Maybe you are right and your flash is corrupted... Did you try to erase some partition?

E.g. "fastboot erase recovery"

[LG Optimus L9 P760, P765, P768, P769] David7578:
Yes, and any partition related command gets a "no remote partition" error.

and as I said, only the usbboot command works in any script, with some PXXX bins that are partly compatible.

Deleting the non working commands does not change anything.

I mean, leaving the scripts intact or just creating mine with only the right usbboot command is stricly the same. I can get in fastboot mode for 2 minutes, but can't write or erase anything in the flash.
[LG Optimus L9 P760, P765, P768, P769] David7578:
Now to progress maybe I can check:

The source code (if available) for usbboot and fastboot. If I'm correct, usbboot is in fact a build from omapboot.

See what's in the bins usbboot sends and search in the P760 images if I have something that can replace the generic ones

See if there's a solution that could boot from the µSDcard. Thing is I only have a 64GB one, I guess I should get one under 4GB for compatibility purposes as a baremetal system image might not be able to handle 8GB or larger partitions.

I wonder if I have enough skills to deal with those, but I'll try to read what I can and try to get something out of this.

Thanks for that.

Now if I could find P760 files, or someones tells me I'm wrong and shows me commands or actions to tell if the device is fried or not... I take ;)
[LG Optimus L9 P760, P765, P768, P769] shinobisoft:
From what I've been reading it sounds like your partition table is corrupt.
[LG Optimus L9 P760, P765, P768, P769] David7578:
That's one of the possibilities I read in various posts/forums.

Let's suppose the flash is still working, I need to either format everything or repair the partition table.

For the moment I lack either the knowledge and/or the tools to do that.

The access to the source code is nice, as I can search for error messages etc.

---------- Post added at 12:29 PM ---------- Previous post was at 11:48 AM ----------

Another question popped in my mind:

"No remote partition"

I can interpret that as:

1) Optimistic: flash is present and has been asked (or the managing process) and the problem is only the table/partitions

2) Pessimistic: the command just got a generic error code while trying to write to a generic/usual partition, regardless of the nand state.

---------- Post added at 12:34 PM ---------- Previous post was at 12:29 PM ----------

Yet another question:

is there a log of some kind I could retrieve after using the usbboot command?

Because It seems in that mode there's not many functions I can use for diagnosis. At least at my level of knowledge.
[LG Optimus L9 P760, P765, P768, P769] David7578:
Seems like I found something of interrest.

I guess I could boot a pandaboard u-boot.bin, as it also has an omap4430. I can try that and be lucky... and have more options to format the nand or other tasks.

But I wonder if that'll be that easy.

Edit:

Didn't work, I knew it might with a 95% probability... since the settings are totally different in the 2 devices, likes what subparts are connected to the omap and how. But well, at least I tried.
[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
If u-boot can be anything you wish to execute, it should be possible to run something that reads/writes the NAND.

Is there any p760 compatible U-Boot source code? I lack of knowledge too but we could try..

Last i heard the p760 u-boot is a lk bootloader which isn't under gpl... Hence why i have been trying to decompile the bootloader to some c source but have no luck outside of some machine code i disassembled to. There is lk bootloader source on caf, but i couldn't find a omap branch, only qualcom. If we had the source we could probably disable the token check and directly unlock it from fastboot i think, not sure if the primary bootloader would be too thrilled about that though since i don't know if theres other security checks besides the efuse being blown to verify it being unlocked.

[LG Optimus L9 P760, P765, P768, P769] David7578:
Ok I understand from that that the code is closed source.

I guess that if I get the right files, I mean the ones from other P760 phones, I can solve my problem?
[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
I think you have to make your own file to execute your own code. There is no file for p760 afaik.

[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
We need someone with more knowledge.. Anyway it seems that here https://github.com/swetland/omap4boot there is source code for aboot.bin.

If I understood correctly, aboot.bin is a running software on the phone so we shouldn't need to send a u-boot too to run our code..

I think that it should be possible to make aboot.bin read the nand and send it through USB. We should also edit usbboot to fetch the data sent from aboot.bin.

As I said I lack of good knowledge so this is just a theory.. [MENTION=5112866]stunts513[/MENTION] what do you think?
[LG Optimus L9 P760, P765, P768, P769] stunts513:
i need to send a nasty bug report to tapatalk so their app will stop making me infuriated when using quick reply and then losing the entire message because it failed to connect to server...

Anyways before i start raging any further, i'm only slightly familiar with omap4boot, i know of it because i come from the kindle community and our devices have omap 4 series processors, but we can only use omap4boot on the original kindle fire 1 because amazon stuck a high security model processor in the newer ones that require a signed aboot we don't have, so i haven't ever really looked into using omap4boot before. I also don't know coding outside of bash, batch, and some javascript, but from my small perspective i would assume that the aboot could be coded to do just what we want but i have no idea. I mean a aboot i think is similar to a u-boot and since u-boot has fastboot mode and we can download images i don't see why we couldnt make it go the other way unless we run into the issue of the fact the data in download mode was buffered in the ram so i don't know if that would be a issue going the other way. I would be more interested in creating a custom aboot with the ability to blow the efuse that unlocks the bootloader, but we would have to find out the way to access the efuse first, probably another reason decompiling the u-boot would be useful.
[LG Optimus L9 P760, P765, P768, P769] sguerrini97:
[MENTION=5112866]stunts513[/MENTION] well, since usbboot talks to aboot and vice-versa, I don't think we need fastboot interface.

I would like to help [MENTION=5827569]David7578[/MENTION] and perform my skills, but if you know how to disassemble the bootloader unlock code that would be interesting too, maybe just the assembly code is needed.

The full NAND (along with the partition table) is /dev/block/mmcblk0 on the phone, but that's a linux device... I don't think that file exists during the aboot execution...

I know a little of C, I'm going to compile omap4boot from source and see if it works. If it does, I can try to play with usbboot and aboot source.
[LG Optimus L9 P760, P765, P768, P769] David7578:
I've read a bit of how this might work and it seems the fastboot interface works in raw, with a start point and length to read/write data.

if I remember right, searching for "partition" in the mmc.c file on github will get you at some point to the startpoint and length of the boot/system/misc etc... partitions.

So either the emmc isn't working or started, or the partition table is corrupt.

The "remote partition does not exist" error isn't helping to know wether the nand is present or not.

In fact, I do not know if we have commands that could get us logs and states for partitions, nand or anything.

Fastboot seems to mainly be a one way communication with only flags for the protocol.

It does not seem to provide partitionning tools either.

---------- Post added at 05:25 AM ---------- Previous post was at 04:52 AM ----------

For the K1, it seems they have a bin that wipes and repartitions the flash. and I think the K1 is an omap4430 too.

I read about it 2 days ago but can't pinpoint a link yet. I remember there was ffff at the end of the filename.
[LG Optimus L9 P760, P765, P768, P769] stunts513:
Yep its a omap 4430, I know that much offhand. I know the kindle fire 1 was unsecured so we could flash firefirefire over the default bootloader. Maybe that's what the fff you were thinking about was. Pretty sure its open source, though I believe amazon used a nice GPL uboot that TI made. Might be easier to try to make a aboot/u-boot with ti's sources even though it is not the same as lk bootloader.
[LG Optimus L9 P760, P765, P768, P769] David7578:
Some progress?

Maybe.

I did myself a P999 with some soldering and a potientiometer [MENTION=2450033]910[/MENTION]k controlled with a multimeter.

After a usbboot command, the device is seen as LGE composiste device for 3 minutes.

The LG mobile support tool needs at least 60s just to check the phone is really there (gosh...) and then starts (maybe) uploading stuff until the 3 minutes are over. At best I've been up to 18%....

Strangely enough, adb and fastboot do not see the phone with the P999, but the LG soft does.

When using a normal cable again, fastboot sees the phone, not the LG soft.

I'm not really in a better situation now, just that I have another option/path and I don't know if I can do anything with it.
[LG Optimus L9 P760, P765, P768, P769] David7578:
Ok, so after fiddling a little more, I'm able to use cmahendra tutorial... but can't complete the process because of the 3 minutes (approx) time limit.

I have to find a way to extend that timer, maybe with an hex editor?

Or I should find ways to recompile the p940_u-boot_fastboot.bin?

I might be fooled by the progression bar, but the victory seems near enough I can almost touch it... Well most losers tell you that afterwards, but the game isn't decided yet, that phone is more like Schroëdinger's Cat :D

---------- Post added at 05:49 PM ---------- Previous post was at 05:39 PM ----------

I wonder if I could use that new interface to upload a recovery or directly boot into it. That would make things easier.

But it seems that most tutorials either use the fasboot method that works (no errors with partitions) or LG flashtools with the LG interface (LGE usb modem and composite device)

I'm now searching for something in between, which is always easy, isn't it?
[LG Optimus L9 P760, P765, P768, P769] David7578:
Since it seems LG tools can communicate with the LGE modem, I tried to connect to the serial interface with putty.

But I can't find the right parameters to connect to the interface.

You understand that my idea would be to enter a mode where I might be luckier and be able to either change partition, or even boot into a working recovery.

Still a failed atempt. Yet...
[LG Optimus L9 P760, P765, P768, P769] stunts513:
I'm wondering if we can do something weird that would sorta suck but be useful, was thinking maybe we could use omap4boot to load a custom kernel into the ram and boot off it, kinda like a tethered ROM boot. Downside to that idea is the system image from cm would be incompatible with the stock ROM last I heard, so literally you would have to boot in omap mode ever time you want to boot up, which would suck if you have a spontaneous reboot. I'm just thinking out loud though here.
[LG Optimus L9 P760, P765, P768, P769] David7578:
I thought about something like this, after all I'm not a programming wizard, so all I can do is try many tools, even if in fact they are not compatible.

being able to load a recovery directly in ram would be great for example.

But it seems the recoveries are usually loaded in flash first, and then at the next boot can start with either a flag or the right key presses.

Trying to load them directly in ram with usbboot didn't work for me. But maybe I didn't use the right ones?

After entering the new server info and teh account tries to setup, I get a message "incorrect username or password," which hasn't changed.

Everything has been fine with my G for weeks. Then today, I heard the boot animation and pulled it out of my pocket to see it rebooting. I thought I had bumped the button, so no big deal. Waited for it to boot, then unlocked it and checked mail.

I set it on the couch next to me, then a few minutes later, I reached over to turn it on and it wouldn't turn on. I held the power button several times for extended periods. I finally held power and volume down and it rebooted.

Kind of alarming, since I haven't changed anything. No new apps, no hacking, rooting, modding. It's stock and I haven't changed anything about it in the last week.

Anyone else experience anything like this?
