LG G2 D802 - Fastboot mode commands not working - G2 Q&A, Help & Troubleshooting

Hi All,
This is my first thread i hope i will get help to solve my problem,
The Phone Model : LG G2 D802 , Stock and not rooted
The Problem : I tried to upgrade its firmware using LG Flash Tool 2014, it has 4.2.2 firmware and i tried to install 5.0.2 Lollipop, but maybe the firmware file is not compatible with the device to its Bricked!
For now the phone is booting into fastboot mode and the computer can detect it, but the problem that i can't ran any command to flash again the 'laf.img' file, tried 'erase' and 'flash' and a lot of command without success.
Here is what i get when trying to flash the laf.img file, i can't post a link because i am a new user :
" target reported max download size of 1862270976 bytes "
" sending 'laf' (15872 KB) ... "
" OKAY [ 0.550s ] "
"writing 'laf" ..."
And it stuck on writing laf ):

Thanks a lot !!

How the heck did you try to install Lollipop from Jellybean..
Use LG FlashTool and go back to Jellybean. Remember you need to flash the recovery first by using a specific root method which gets around the bootloader verifying the image - or something along those lines.

[Q] [HTC][HERO][GSM][ISSUE]How to flash?

Hi Guys,
i have a very specific issue.
Its HTC hero which been upluged before finishing official upgrade to froyo.
So, where is the problem?
Hero cant boot, all the time just stay stucked on "HERO" boot animation. The problem is, that it was upgrade from stock Eclair to stock Froyo. They didn't have any root, or recovery (CWM, RA, nandroid)...
The phone can be started in hbot, fastboot, stock recovery.
HBOT->
I've found this > http://forum.xda-developers.com/showthread.php?t=575448 < but i think its need a function hero to set up setup.
So there is no way i think
Fastboot->
I've try to flash recovery with AR, CWM via
"fastboot flash recovery recovery.img"
but only get this

"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Stock recovery->
I've also try to flash via "apply update.zip from SD card" from this
http://www.modaco.com/topic/291942-22jan-stock-roms-radios-in-updatezip-format-for-gsm-hero/
every single file crashed "E:Verification failed!"
I'm such a big noob, but is there any way which i didn't try? Something like flash CWK recovery mode via update.zip? Every idea can help.
Thanks
Do you have your hero drivers set up on your PC?
Also, when flashing recovery.img using fastboot, please rename your clockworkmod.recovery.blablabla.img in recovery.img and then try to flash again.
as i thought so
prntscr.com/aun85 <its a link, but i'm newbie here, so i have a constraints
but its exactly the same as the file was named clockwokrmod.....img
Driver should be ok (get from android-cellphones com)
Q: how can i access the adb? In device manager a use this driver. But in cmd "adb devices" cannot find my hero. But idk if it helpfull.
Sorry for my english
When your phone is plugged in your windows PC (in hboot mode), check that the driver installed is called My HTC (in device manager), then download the latest RUU under HTC Hero support site (not the 2.1 one) and run the program, it will erase everything, but if it is successful it will install the 1.5 system to your phone, and you can start over
Sent from my GT-I9100 using xda premium
Problem was solved via hboot mode. Thx guys

Is there a way to reload the factory recovery partition?

Hello guys, just wondering if there is a way to reload the factory recovery partition?
I am getting a demigod error and cannot do anything in recovery once I try to restart into it, but the phone when restarted works fine with the factory image.
I tried to load a custom rom and done screwed up
I did make a recovery backup, but I am pretty sure I screwed it as I was trying to copy recovery.img to the phone during some un-bricking troubleshooting.
Thanks
Okay guys, I know I should be doing my own research but I'm stuck.
I found this youtube video:
https://www.youtube.com/watch?v=hQVTc2m6U-I
I've downloaded all of the LG G2 D801 T-Mobile files:
http://downloads.codefi.re/autoprime/LG/LG_G2/D801BK/Stock_Firmware/20a_partitions
I am able to get ADB to recognize my device and I am able to 'send' commands via fastboot BUT my phone doesn't seem to accept them.
I've tried via command line and using SRK tool:
Here is what happens when I try to run the fastboot commands in fastboot mode (UP button + USB plugin)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here is what I get when I try to run SRK Tool:
So as you can see from the output, the phone is detected and it seems like the files are in the process of being 'sent' but nothing actually installs.
When I was doing it in command prompt, I let it sit for a few minutes for a few commands and they just sat there at writing.
On the phone itself, this is what it states at this moment:
[500] fastboot mode started
[500]--reset--
[500]--portchange--
[500]--reset--
[500]--portchange--
[500] fastboot: processing commands
[500]fastboot: getvar: partition-type:laf
[500]fastboot: getvar:max-download-size
[500]fastboot: download:00e00000
[500]fastboot: flash:laf
That's all I get on the phone, nothing changes. It just sits there idle.
I am unsure what to do and was wondering if anybody knows how I can fix this?
So I seem to be having some kind of issue with the phone not accepting fastboot commands and/or my computer is not recognizing fastboot.
I did install the ADB/Fastboot installer. I have Java and SDK installed.
When I try to run ADB devices, it identifies the device.
When I try to run fastboot devices, all I get is:
command prompt> fastboot devices
? fastboot
That's all.
Anyone? I am having the same exact problem and have not found a fix yet.
Look at my last reply here: http://forum.xda-developers.com/lg-g2/help/g2-fastboot-mode-t3427770 it may work

Lost recovery but Rom OK?

I seemed to have lost my recovery but my phone is otherwise working.
I went from CM13 with TWRP, downloaded OS3 from the official oneplus web download as well as the "optional recovery" on the same page.
I wiped data/system/dalvik/cache and flashed the OS 3 zip.
I then flashed the stock recovery img.
Wiped again.
Rebooted to recovery from TWRP and got stuck with the oneplus logo. Completely non-responsive.
Fearing I had softbricked the phone, I started with ADB, got the Qualcom HUB listing under Device Manager and was about to start the process of updating Qualcom Drivers and running the recovery tool (having not been able to get fastboot to see the device) when a miracle happened and the phone started booting up on its own. After running setup, I rebooted, no problem.
I have since been able to use fastboot oem lock and confirmed the phone is locked (I wanted to get back to stock).
Everything is working fine EXCEPT I don't seem to have any Recovery at all. If I use the Developer Option for Advanced Recovery and boot into recovery, I get the oneplus logo. If I use Vol Down and Power I get the oneplus logo.
I think I have lost my recovery but recognise that I am out of my depth and don't want to stuff up the second chance I was given by trying to flash a recovery (I want stock receovery so I can get OTAs in the future). BTW, I read extensively before I tried this, looking at a number of different sites and followed instructions to the letter (or at least I thought so!).
Could someone who knows what to do please help to get my recovery back? It would be very much appreciated.
Edit: I managed to fix it. You have to use the Qualcomm tool and go back to OS2.2 and then update to OS3. See the link below and follow Method 1, doing everything exactly as set out.

Meizu pro 5 have rooted rom but lost recovery - phone can boot pls help!

Hi
i was stupid enough to unlock my bootloader and flash recovery, then reflash back latest meizu stock via twrp , and flashing again the twrp recovery image,
i don't why, but the first init of the rom update ****ed my recovery up and now i lost recovery (even the stock, the phone just booting to the rom)
fastboot oem unlock isn't possible because i'm on locked bootloader rom.
i tried to flash the recovery via rashr with the backup i made and i can't becuase of busybox, i guess it's because the bootloader lock
is there any script or way that i can stock recovery back?
actually if lost the rom i lost my phone....
please help!

HELP! Zenfone 2 Laser (ZE550KL) bricked!

Hello guys! Happy xmas! I've tryed install the CM13 in my smartphone and i had a problem during the install. The cellphone just start in fastboot mode and i lost my TWRP. I can't install any custom recovery and any another custom rom. For now, i'm installing UL-Z00L-WW-1.17.40.1531-user firmware and this problem appear:

Can u guys help me?
What I would do:
step 1
make a FULL partition dump, backup all files including modem modemst1 modemst2, which contain the important imei specific to your phone
step 2
charge phone battery to full, download all available versions of updates from asus, copy all to sdcard, install/update one by one, until the latest. This ensures you get the latest modem firmwares.
step 3
root, unlock the phone
step 4
complete step 1 again, yes!!!! it must be done.
step 5
install custom recovery (twrp), then install cm13
VERY IMPORTANT: backup always and frequently, flashing Asus updates or custom rom can easily corrupt the EFS partitions (modem, fsg, modemst1, modemst2)
if u have computer, then adb sideload the firmware file
select update from adb
command - adb sideload filename.zip
be confirmed that the adb drivers are installed for ur mobile
So, guys, i tryed this methods but does't work :/
I'm trying now install a system.img but i'm stuck in this problem:
Can u help me?
