[Q] d855 32GB only fastboot mode, no recovery, fixable? - G3 Q&A, Help & Troubleshooting

Hi
I tried the one-click root method on my d855 32GB running stock 5.0 but now it doesn't get past the LG logo screen (said successful). I can get into fastboot but get a device error when trying to run LGFlashtool.
Strange because it started flashing in LGFlashtool but stupid Paralells VM (I'm running Mac) installed some kind of tool and autorebooted in the middle of the flash! Can still get to fastboot but get device error.
Any advice on if I can get this up and running?

You may have to flash stock firmware here.

Thanks. I can't get it to flash using Win 7 VM. I'll try tonight on a dedicated PC and see how I go. Got the KZ file but seems my IMEI etc is all corrupt (still got it on sticker under the battery) when I go to read phone info through LG Flash tool....
Had the phone for two days

Fixed! Had to use another computer rather than VM on a Mac. Also had to try it a few times. Actually flashed the kmz then had to flash the tot method. Least that was the combo that worked. So relieved.

Sprint LG LS980 (OptimusG2) stuck in download mode or stock recovery

Hi all. I'm not a novice when it comes to rooting and flashing but I'm stuck on this one. A friend of mine tried to install CM11 on this phone, the LS980 and somehow really jacked it up. It's stuck in a bootloop, but I can get into download mode and stock recovery. All data has been wiped. I have tried using the LGFlash tool to install the stock tot and dll but it fails. It fails because the the tool says the file is the wrong model for the phone. Here's the thing, its not. But somehow the phone now thinks its a D802 instead of an LS980. (This happened during the CM11 attempt somehow) The flash tool fails every time. I even tried the D802 files and it started to flash but failed about a 1/4 of the way through. That confirms that the phone definitely thinks its a D802, weird. When I hook it up to the LG Support tool, it tells me the phone is a testmodel!
Needless to day I've tried everything I know how. ADB sideloads, different recoveries, and I've researched for hours on end. I have hope that there's still a solution. I would be golden if I could get a recovery on it, either TWRP or CWM. Any help is appreciated.
have the same problem. simply cant recover the recovery.
My recovery for e988 g pro in lg g2. I try everything for fix the recovery but cant help it. Is there any way to re build recovery?

Hard bricked VS985 after ROM flash failure

Sorry, I'm relatively new to rooting and I looked through the threads and found similar problems, but none that seem to exactly match mine.
I have a rooted VS985 that I was trying to flash with the AndroidNow HD 6.1 ROM using TWRP and I guess the flash tool crashed. It was stuck on a black screen for an hour or two so I hard reset it and after that, the phone will only flash the LG logo for a second before the screen turns off and the indicator light alternates flashing red and blue. As far as I can tell, the computer does not detect it when it is in this mode (seems similar to the secure boot issue that some people have been having). I cannot enter download mode (the LG logo flashes on and the indicator light flashes blue once and then both turn off) but I can still boot into TWRP Recovery. When I try to boot into download mode, even while the screen is off, my computer detects the phone as QHSUSB_BULK. Also, when in recovery mode, my computer can detect the phone as a G3 and I can access it with adb tools but I don't know where to go from here. I have tried using the LGFlashTool but I can't seem to access the phone because it will not enter download mode and I've tried reflashing AndroidNow HW 6.1. The flash completes and says it is successful, but the phone still will not boot properly.
Luckily, I got the phone a few days ago from Costco, so there is a good chance I can still return it, but I would like to fix it if I can.
Any help would be greatly appreciated.

You said you have adb working.
Did you make a backup of your stock download mode at anypoint of time? (Iaf.img)
I guess it can be pushed back using adb, but am not very sure. Even if not, maybe you can take the stock Iaf.img from someone else and try pushing it via adb using this command:
Code:
dd if=/storage/external_SD/stock-laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf
Then you can boot into the download mode using the command:
Code:
fastboot boot stock-laf.img
It doesn't look like I have the stock laf.img backed up. I'll try to get it from someone. Thanks, I'll let you know what happens when I get it.
I need this tooi fi h
had a nandroid backup but accidentatlly delted it when i formatted my internal memory now im stuck on liquidsmooth custom rom cant get into download mode so kdz/tot will not work for me...

Yes I flash it back those v20a bootloader, boot and modem after I got into the twrp, then I reboot it, it is stuck on the LG logo screen now...
and now I can't go back to the fastboot mode and the twrp...that 's the problem...
any idea to go back the twrp?
i'm stuck on same thing.
What I've tried.
! flashing back to stock rom using lg flash tool. Crashes at 9%. Tried flashing 20A file not allowed
both adb and fastboot methods don't work as adb doesn't detect phone and fastboot get's stuck on waiting on device
Basically the phone is stuck on boot logo after upgrading to marshmallow which all went fine and phone booted as normal after I then reinstalled the twrp recovery as before so to install supersu after boot that when the problem started. The phone can get into factory reset the two yes methods which I have tried still no luck and I can also get into download mode. basically am I waiting on a update to lg flash tool or have I ducked my phone any help would be appreciated
You probably ****ed the security flag added into marshmallow and it didn't like it one bit,that's why its better the flash newer versions of a rom when you have a recovery then an official ota ,that's where they get ya locked down .is there any devices in the device manager at all? Just checking if its hard bricked.if its labeled as q9xxxx something like that then its definitely hard bricked.like not even a jtag can get er back

No its listed as two different devices as LGE andriodnet serial port com4 and also LGE andriodnet usb modem. I have noticed that if i uninstall these two from within device manager that it then goes back to an lgmobile phone with a i on the phone icon in device manager. I have tried to find the proper driver so to make the computer see the lg phone again without error via extracting driver install exe but no joy it goes back to the above.
I wonder Is it possible to flash the .img files that are boot. system etc using lg flash tool the one with the tot methid via a script and the files I wonder. Or even convert the files needed to do a complete flash of system bootloader etc to bin files so to be read by the lg flash tool used in the tot version. or is there any other software that can convert kdz to bin.

I think this is impossible to flash the .img files that are boot. Because we cannot to go into the fastboot mode.

:highfive:In the same boat, XDA's brother TheBledard Who has a same trouble in the bootloop. He said that you can use the octopus box to unbrick.
But it seem a little bit expensive....:cyclops:
Same
I had the same problem. They recently reposted the download to a fixed 2.6 so try to redownload from the genesys post. Also, flash the marshmallow kernel and supersu right after, then followed by genesys theme if you choose to use.
Retry and retry to start twrp at boot with sleep button and volume down button.... I had the same problem with marshmallow because i forgot to flash v20a bootloader, and i had finally access to twrp after a lot of times...

Need help. Flashed incorrect rom on my Vk810.

Im not that experienced but have been playing around trying to learn about roms etc. I used the flashify app to flash a rom but accidentally used the wrong rom. I grabbed the one for the v500 model instad of vk810. Needless to say it messed up. When the tablet boots it stays on the boot image for several minutes then it will attemp to update apps but gets stuck there. I have tried many fixes. The LG mobile tool doesnt work. I try to update recovery. It downloads the update but wont install. I cant force the tablet into recovery with button pushes. I have been able to put the tablet into twrp 2.7.8.1 recovery with droid explorer. From there I have tried to flash about 3 different roms that all say they should work for the vk810 but i get errors with all of them and they fail. Im not sure if there is any hope to get the tablet working again but hope someone can help.
First, I don't think you can use Flashify to flash a whole ROM at all. Definitely not recommended, even if it's is supposed to be capable of doing that. I haven't tested flashing ROMs with it so no idea if it can work or not.
Can you put it in Download mode? If so, install the Verizon LG drivers, reboot the PC and try LG Flash Tool 2014 with the 11A KDZ, you can get the KDZ from the link in my signature. It's easiest to root and put TWRP back on that old stock ROM.
FYI it would have to be in Download mode for the mobile tool to work - just in case you didn't know or didn't have it in Download mode. LG Flash Tool 2014 does the same thing as the mobile tool except the mobile tool re-downloads the newest KDZ every time you try it unless you hack it. It's much easier just downloading the KDZ separately and keeping it on file for times like this to flash with LG Flash Tool 2014.
Just remember, if you use LG Flash Tool 2014, ignore any error it throws at you. Just drag the dialog boxes out of your way, don't press any buttons in error dialogs. 99% of the time, if you just ignore them within 10-20 minutes it'll have successfully flashed your VK810 anyway.
Also, once you install the drivers and reboot, put your original USB cable that came with the VK810 into a USB 2.0 port on the PC, with the tablet completely off, hold the Up Volume button in, connect the tablet end of the USB cable and keep the Up Volume button pressed for another second or two, and you should see a very dim "Download Mode" graphic in the center of the screen. It's very hard to see. The first time you connect the tablet in Download mode to a different USB 2.0 port or Windows installation, it can take up to 10 minutes to actually load the driver you previously installed. Look in Device Manager under the Modem section to see when the driver is fully loaded by looking for the LG device entry there.
Question: I assume you mean TWRP v2.8.7.1, but I was just wondering where you found 2.8.7.1? I've only found 2.8.7.0, not that it's a big deal.

Soft bricked my ls990!

Hi, hoping someone out there can point me in the right direction!
I purchased a second hand G3 LS990 running ZV4. Since I do not like running an old OS I decided to flash it to ZV8 and had some issues with the modem so proceeded to use TWRP to install PrimeGSM which worked fine..
A day later I thought I'd attempt ZV8 again with a different modem, when starting the TOT flash method I found on this site I noticed that the phone was being detected as a D855 so tried various DLL files and kept running into the CrossDL issue so made the mistake of trying to flash to a D855 rom, three Roms later I had a brick!
The phone currently freezes at the LG Logo, although I am able to get to fastboot, TWRP via fastboot, and Adb via Cyanogenmod recovery.
Fastboot is unable to erase or format partitions, also cannot flash and fails with write failure.
Adb cannot push files and fails with error closed.
All attempts to use fastboot update "rom.zip" fail due to the hardware version so I tried to merge a d855 and ls990 CM build which fails with either a baseband or signature mismatch..
I have been reading up and trying all sorts at this point with no progress in the last day so thought I might try a post before telling the wife I need a new phone!
Any assistance would be greatly appreciated. Let me know if more information is needed.
PS. I know there allot of these threads out there but after digging through the first couple Google pages of each search I have not found one solution which works for my phone.
I managed to get the phone running again by following a guide I found in the forums
Havent read the guide but also happened to me to fix it i was lucky enough to have access to the os and to dl mode but not recovery and i too had different firmware on my phone so i changed the build prop to a ls990. Unaltered build prop, changed permissions accordingly and powered it off. Plugged up to lg flashtool and used the original ls990 dll with zva tot and bam got it flashed no problems.
Sent from my LG-Ls990 using XDA-Developers mobile app
