[Q] Guys, please help - G2 Q&A, Help & Troubleshooting

Okay, maybe starting a new thread isnt the best option, so sorry, but i really have no other option, i have surfed through the forums to no avail.
My friends G2 (D802 32GB) arrived with stock firmware V20B, and there were some problems, so i tried updating it to V20D Using the following kdz method.
http://forum.xda-developers.com/showthread.php?t=2432476
But i had rooted the phone on V20B (and im assuming thats why ) I lost download mode and recovery mode, when attempting to go to download mode, it goes to fastboot mode, so i used the following method to reflash the download mode
http://forum.xda-developers.com/showthread.php?t=2477595
I succesfully did revive the download mode, and attempted flashing through kdz again, resulting in being able to go to recovery and download mode (The download mode said rooted, i dont know why, shouldnt reflashing remove root? (CSE flashing)). But the phone was stuck on the Lg logo, so then i attemted the tot method, in which the update fails, something to do with Fota, i couldnt get it to work, so then i tried Flashing the V10B(Which was stupid of me) through the kdz method, and then, after flashing, the recovery was there (it was a bit different than the one after flashing V20D), but then, Its stuck at download mode, the download mode keeps loading forever, and also, no drivers are detected by the pc. (However, connecting normally gives USB composite device ) and i dont know how to proceed. I did my research and found nothing that helps me, im scared that the phone is already beyond repair, so yeah, i would really appreciate your help
As you can see, im a bit of a noob, so excuse my ignorance.
Isnt there anyway i could force fastboot mode?? or maybe some how use adb? The stock recovery is accessible, is there anything i could do?? maybe install a custom rom somehow or something??
Again, sorry, I just hope the phone can be unbricked :|
Thanks

[Q] Soft-brick? ADB sees the phone.

Hello guys, I have a problem with this phone.
First I flashed the euro+fastboot kdz... The phone booted and worked awesome but It wasn't showing recovery or LG logo.
Somewhere on this forum I read that you had to flash v10c and then v20B to fix this.
I did so, v10c failed, but v20B flashed correctly, but it didn't boot up.
I'm still stuck here, the phone is completely dark, but when I connect it to the pc I can see it with ADB, It just doesn't go into fastboot mode (because of v20B I guess). But flashing the euro kdz won't work anymore, and I'm stuck in ADB without fastboot.
Hope you guys can help me,
Juxter.

flash first french firmware _hxxp://csmg.lgmobile.com:9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz

dont boot android , remove accu reinsert them and press vol - and plug usb cable into port on mainboard - you must get in download mode )
flash firmware with fastboot (i use CIS _hxxp://narod.ru/disk/26675062000/V20B_00.kdz.html)
boot android and flash this firmware _hxxp://narod.ru/disk/25473801000/out.kdz.html

So after 4 5 6 or maybe 10 times, it will finally become working, that's what you're saying?
This is really odd, something's wrong with these phones lol
Okay, i'll load myself with a ton of patience and repeat the steps as per the instructions. This is *exactly* how i am doing it, with all the details:
1) Using the French v20A ROM - http://csmg.lgmobile.com:9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz and this Russian one - http://narod.ru/disk/25473801000/out.kdz.html
2) Take out the battery, SIM card and SD card
3) While holding the Vol - button, plug USB into phone so that the phone goes into Download Mode
4) Run the KDZ Updater, put it into CS_Emergency mode
5) Select the French V20A rom and flash it
6) When it's finished (immediately after the DOWNLOAD MODE letters vanish), i pull out the USB plug from the PC, so that the phone doesn't boot.
7) Again hold Vol - and reinsert USB to put the phone back in Download Mode
8) In KDZ Updater (still in CS_Emergency mode) select out.kdz and flash it
9) Let the phone boot into Android
At this point i STILL don't have a boot animation, should i keep doing this until i see one appear?
When it (if) finally appears, i just flash my own ROM, do a factory reset and it should stay that way, correct?
I guess my impossibility to access recovery mode also has something to do with this...

Note: For above step: 1) Using the French v20A ROM
-- as long as you have the ROM of v20 with fastboot option, it doesn't really matter.

Hope this helps.
Thanks for the reply, I actually fixed it following this:
hxxp://modaco.com/topic/329863-how-to-raise-gt540-from-the-dead/
Once I got fastboot with that cwm.kdz I reflashed a fastboot rom, and from that one I could use the KDZ updater again, following the French kdz procedure...
The phone now is fully working recovery and bootanimations again

Bricked G2 - Fastboot only/No download mode (Beer money for anyone who can help)!!!!

Hi Guys,
I brought my LG G2 D802 32GB last week and I believe it's possibly hard bricked if not soft bricked so let me start by saying that anyone who can help me get my brand new G2 working will be receiving some beer money!
I've owned over 15 android devices over the years and i'd say i'm a competent flasher but I've never had such a problem flashing any of those devices as I have on the G2!
So here's what I did:
1) Updated Phone to 4.4.2 and rotted using IOroot method (Root was successful)
2) Install LG USB Drivers
3) Flashed CWM 6.0.4.4 (Flashed successful and CWM was working fine with Root access on ROM)
I then decided to put TWRP as the recovery because after much research it seemed to be the most popular choice.
4) Downloaded D802_AutoRec.apk (I believe this was the correct recovery for my device)??
here's what happened:
After using AutoRec to flash TWRP recovery I rebooted and the phone displayed:
450 Fastboot mode started
500 udc_started()
Plugging in the USB cable then adds the following lines:
660 -reset-
670 -portchange-
740 fastboot; processing commands
Note that Download mode WAS available at this point.
I then tried flashing CWM recovery again through fastboot which showed as successful but still stuck in fastboot after rebooting. The same happened for TWRP.
I then went to the LG website, put in my IMEI number and downloaded the stock ROM (D80220C_00). I used the G2 extractor to extract the kdz to a DZ file then extracted the aboot/boot & laf.img. Since I did this I have lost download mode!
It's interesting to note that fastboot shows attached device as:
? fastboot
and ADB shows no attached devices.
I'm not sure this is relevant as I still seem to be able to push commands to the phone through fastboot?
I then tried to flash the stock ROM (D80220C_00) using LG Flash Tool however it gets to 27% and says "cannot connect to the phone
So as it stands at the moment all I have is the option to flash using fastboot, I have no download mode, no recovery or no working ROM. Have I completely bricked my phone or is there anything else I can try to get the stock ROM back on there?
Any help is massively appreciated!

[Q] [BRICKED] LG G2 Can't flash. Trouble with Download Mode.

Hi. Im a new user on XDA. First of all. Sorry for my bad english haha.
Ok lets go. My big problem its my LG G2 D802 32Gb. variant unlocked stays in a infinite bootloop. I can't access on the recovery mode to make wipes, etc. An i cant flash any roms on the download mode. I can acces on the download mode but my laptop Don't recognised my d802.

I will lose all of my data :(

Hello guys! I bricked my device, so it doesnt boot right now. I was on Cloudy Flex 2.8, then I wanted to flash Cloudy G2 3.3 (G4 ROM), but my phone was bricked. I wanted to solve these problems with SRK Tool. I did this option there: Unbrick - qhsusb_bulk 9006 (No Recovery Mode,No Download Mode).
Now, I can enter download mode, but afraid of entering recovery cause I think custom recovery lost, that's why If I try to enter recovery device will be factory reset. PC doesn't see my G2 Device gets "Security error" when boot. So, I dont know what I must to do. Want to back to stock but If I used to flash stock roms with kdz or tot methods after I must do factory reset And I don't want to do it. How can I backup my datas right now? And can I rescue my device without flashing stock Rom? Thanks in advance! Regards!!!
OMG Noone can help me :crying: Please, help me friends!!! I cannot do anything right now

[Q] Broken Download Mode

Hey!
I have a problem with my LG G2. After unbrick my phone and successfully instaled Cloudy G2 3.3 I can't get into Download Mode. I think i might broke it while I've been trying a few methods to unbrick my phone. But after all I went through I'd like to install stock rom by KDZ and stop being worry about my device. But first I need to fix download mode somehow. I was thinking about flashing laf.img by TWRP but I'm worried that it may break my phone and leave me with no download mode, no system and no recovery.
Any advice?
