Root [Sprint] LG G2 Stuck in fastboot mode. PLEASE HELP!

Ah yes, I forgot the d800 does not have a kdz. You will in fact have to use the tot method. Let me know if you have any specific questions on that method. The part not well covered is the absolute need to change your device to com port 41 in device manager and the steps to do that. Again, ask if questions.
 
Ok, I understand.

Some questions can disconnect the phone to install drivers LG united?
Then I can go to download mode without problems?
I'm downloading the correct firmware (check the image in the above message, please)
Note that the phone screen says "Do not unplug the USB connection" and the phone is hot.

You have a permanently working download mode now so no need to worry. Unplug phone and you can long press power once again to turn the phone off and fully exit download mode. Then install drivers, then go back into download mode once phone cools down.

Well, I've done exactly the instructions in the tutorial for the TOT method. As yet proceed to flash TOT and the DLL file, LG flash tool throws me the following error:

also on the screen of my phone I throw the following message:

USER s0.0 AS0.0 B98 UHS
U S LG-D802 04.4.2 Hrev_11
D80220b


I'm getting my phone says it's a version D802 and flashtool says this flashing a system for d800 version instead of a system for version D802

I am totally confused.

That certainly is confusing considering your internals. It's possible your IMEI was switched, leading the tool to believe your phone is a D802. Would not be the first time I've seen this. Also, they may have just flashed d802 firmware to your d800 phone. With LG, this can fly in many cases though some limitations may result. Your options are:

1.) try to flash d802 firmware instead, particularly if that works better for your situation. Though it could fail to boot because your phone is not a D802 in reality. Most likely, worst case scenario is you end up back in fastboot mode though I cannot guarantee that.
2.) hexedit the tot to trick it into believing it's a d802 while actually flashing d800 firmware*

*This is done by opening the D800 tot in a hexeditor and changing the model number from LG-D800 to LG-D802 (or similar wording). Then save, exit and flash. Pro tip on that: most hexeditors have a search feature, so search for "d800". You may see more than once instance of that. Should only need to change the one that lists the full model number, leave the others (if any) alone. Then it will pass the model check.

Sidenote: if we were somehow wrong about it being a d800, this could cause a brick. It'd be ideal to remove the dust covers which cover the mother/daughter boards because I think I remember they are stamped with the actual model number. You seemed to have rather compelling evidence of a D800, but that might help further verify our suspicions. Up to you.

If you want to know what I'd do if it were my phone...I'd go with option 2. Provided that you can live with owning and operating a d800 moving forward. My philosophy is to follow the internals, they don't lie. :)

ok, I decided I'm going to try this version:

OPEN D80220B_00.kdz Europe 1662200KB

from this link:
http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/

I remember that is the Android version of my phone.
d80220b

If my phone screen says it's a D802 then is able to assimilate this KDZ. I guess the factory rom worked this way. That you about it think?

Guess I'll have to use the method KDZ.

Then I'll tell you.
 
Well I followed the KDZ method, but the flashtool throws me an error telling me that he did not recognize the phone.

I try again but it throws the same error.

See in the image.

I really didn't think there was a need to connect to any server using that tool. Rather, I thought it just used the downloaded kdz stored locally on you machine, and applies it?
 
I also strange that., Am I supposed to install from a file KDZ
Look at the picture the error.

If that's true then as it is possible that the phone got my D802 used a rom and worked perfectly?

Yeah its most likely what the seller did in the first place. They had a d800. They used a d802 tot and hexedited it to show d800 so it would pass the model check. They swapped out the rear cover with a d802 so anyone looking at it would think it was a d802. They don't expect people to ever pull off the rear cover and investigate.

So yeah it will likely work to flash a d802 tot. The reason I'm not positive is that if somebody were very knowledgeable, they could instead flash individual partitions to make it work if a straight up full d802 tot flash does not work on a d800.

Well, I tried unsuccessfully to flash one D802!

I surfed the web and came across a staff with a similiar problem.

http://www.reddit.com/r/lgg2/comments/2ltd0f/flashed_the_wrong_firmware_on_your_lg_g2_read_this/

Basically, you have to edit the file and replace TOT d800 word for word D802. Since my phone thinks it's a D802.
Apparently this is impossible in Windows, Linux is needed for this using: Bless Hex Editor

I've never used Linux, will be a challenge for me.

You can do it in windows also. There are hex editors that work on win.
 
gunner445 said:
I used different editors and have not worked for me, which you recommend?

Thank you for your unconditional support.

I don't know which one to recommend but I recently worked with somebody who used windows. Unfortunately not sure which hexeditor he used.
 
Okay, this is one that I've used before:

http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm

and it seems to also/now still work on Windows 7, too.

It should be pretty simple and straightforward to use--lemme know if you need help and I'll pull mine up in parallel.

Cheers and best of luck, @gunner445.

Hi, thanks for your help.

I installed the program hexadecimal editor that you have put here, but when I try to open the TOT file, the program hangs for a long time doing nothing.

This is the TOT file size: 3.00 GB (3,231,186,944 bytes)

Oh my! No wonder the program is hanging due to the very large file size...

Not sure if it's trying to load it all into memory or not.

Is that file really that large?
