[Q] Problem re-flashing Swiftdroid

It seems that I'm in a pickle here.
I already had swiftdroid installed but then I wanted to re-install it. So I tried but after flashing euro+fast.kdz , I got stuck in boot-loop. I tried doing the steps but I think I might be doing something wrong. Well, to get into fastboot to test if it went through would be holding the "camera" button or is it "home+camera" button during reboot? Thanks. Been at this all day.
Oh, and it appears every time I try to power on and hold the camera button first, it just goes to a black screen. So, by that have I already installed the rom properly even if it gets stuck on the android logo?
and an update as to what's happening:
going into download mode detects my phone on "device and printers" but as soon as I click on "Launch software update" I lose all the icons and KDZ returns a message saying "Phone was not found" I just noticed this now. What should I do?
I already uninstalled all drivers installed on my pc and re-installed them. After doing so, my phone detected a whole bunch of LG devices. Now on Android logo -- That after doing the Euro+fast and now am trying to do the out.kdz. By the way, even if my phone restarted during the "Launch software update" I waited for it to say finish right before I took out the battery and the usb cable.
After param 207 my phone went into boot stage and my pc re-detected the LG stuff. Now my phone is on the LG logo and it's been like it for a minute+.
I am following several steps on doing this procedure.
--Now question is again.. After this step should I be able to launch fastboot via "holding the camera" button? Do I need to do this while the phone is plugged in to the computer?
......
already tried euro then the out then euro using phone cs_emergency. Currently on Android bootloop. So I think I'm kinda back to step 1. Because initially, when I had swiftdroid, I just did euro using phone diag then afterwards, it went to bootloop. Now when I tried to restart my phone then I press and hold of the camera button, phone goes into a black screen. But looking at the "devices and printers" page, it shows "unspecified--android" on the bottom. What should I do then?
So right now, I'm currently on Android logo bootloop and if I reboot then hold the camera button, it goes to a blank black screen. What should I do next? Thanks
Update:
so yeah, after dwelling on the black screen, I tried to open up Mur4ik's old thread looking for the files I downloaded last year. Tried the command prompt and typed this in
fastboot -w
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
After doing so, phone rebooted okay. Right now, phone status seems fine. Some adventure I had. Will try to work on how to upgrade the version on this unit.

Nice work dude I too did all that stuff, its really adventures
Now I came over it and now I'm trying all roms

[Q] Clean Rom won't boot on new G2

Hi All,
I just rooted and put the latest TWRP on my new Verizon G2.
I installed clean rom 1.0 and the install finished succesfully. when trying to reboot for the first time after install, I'm stuck at a black window immediately after the LG logo splash screen, which only has the following information in small writing in the upper left corner:
[810] Fastboot mode started
[860] udc_start()
I can't seem to get past it and can't get back into the recovery. Any ideas? I'm stuck without a working phone right now.
Thanks very much!

Did you flash the one for the Verizon phone?

If you flashed the one in the op then I believe you need to flash back to stock because that one in the op is not intended for Verizon. His link has been down for quite some time now. But head over to general forum and look for Verizon back to stock... Takes about 30 mins to get it all setup and done. Then reroot

What method used for root and recovery?
What method are using to flash ROM?
You check all your md5s?

Full clean etc
Did you:
a) nandroid backup
b) factory reset
c) clear caches
d) install rom
(standard procedure I realize)

Thanks for all the replies guys... appears to have been a bad download. Haven't had one in a long time so I was lazy checking the MD5s last night.

Just repaired this at my shop by taking off the back of the phone & back plate above the battery & unplugging the battery.
turn on LG Mobile support tool
Go to Options & select upgrade recovery
Plug back in battery & press volume up while plugging phone into computer to trigger download mode
Let the LG Mobile support tool work & reload the operating system
Good Luck

recovery broken..

Will the phone boot normally so you can get to play store or it just won't boot at all? Are you using volume down and power, just making sure? Sometimes it can be finnicky like that.

ok i just tried it manually and the factory reset screen showed up, but when i pushed the power button twice the screen went black with the backlight on...

OK, try downloading quick boot from play store and TWRP from play store. Quick Boot will give you an option to reboot directly to recovery, try that first. Then, if that doesn't work, you can try running TWRP app and that allows you to flash a new recovery using the TWRP interface whole your phone is running. You may want to go to the TWRP website and download the most current version for your model first.
Edit: just use the TWRP app to install or reinstall the actual recovery you downloaded from the TWRP site linked below.

thank you i will try that now

The black screen with white lettering in the top left corner is the bootloader.
If you have adb you can download a new twrp recovery image and do a "fastboot flash recovery path_to_recovery\recovery_name.img" and then try rebooting into recovery. It should work fine.

This is what appears in the top left of the screen when the LG splash pops up for a split second and goes black if you were curious.

That being said, you need to push a working recovery onto the device. If you can get into android, then you can access ADB from there and push the working recovery. You should be able to find the latest version of vzwG2 twrp in the g2 general section.
If you can't get into android, then you're ****ed as far as I'm aware. However, if this is the case then you can send it into LG and they will fix it right up for you

I've heard some people say that LG just reflashed the phone while they left root on there. I completely formatted the phone so there was nothing left on it before I sent mine in just in case.

You can't access ADB unless youre in android or a recovery, and you are in neither. You would usually be able to access fastboot (similar to ADB) which is another safety feature so you dont get bricked, but from what i've tried in this state i haven't been able to get into either.
You can try to play around with the android partitions in QHUSB_BULK and potentially fix it if you restore a recovery or something along those lines. But like I had said, I had no success with that.
Your best bet is to send it format the device and send it into LG so they can reflash everything.

Same issue, fixed it today
I had the same issues with a non-loading boot loader & a non-booting ROM. Follow the instructions in the thread linked below to restore stock firmware, and then root, TWRP, and install a custom ROM afterwards. The link to the LG Flash Tools was not one that worked for me, but a quick google search will get you the right file (top 3 results proved fruitful for me).

G2 wont boot to download

Hello as the title says my phone wont boot into download mode. I got the phone and downgraded it and was able to root it. The phone was working perfectly all day, I plugged the phone in at night and went to sleep and i woke up and the phone was booted to recovery (Philz Touch 6) and when i try to reboot the phone it shows the LG screen then goes straight to recovery if i power off and hold the volume up button the phone still goes into recovery and trying "adb reboot download" wont work, it just hangs in terminal and never completes command.

Sounds like it did an ota update without your permission as lg does try wiping caches data system not I ternal storage your going to have to flash a custom ROM through adb sideload

[Q] LG G2 D802 Bricked..help me please

Hi!
I managed to get my device totally bricked.
Phone is on bootloop and I only get LG logo and then "Security Error" message. I can't enter recovery mode or download mode. Only mode I'm able to go is the "Hardware key control mode" mode, where I can see my IMEI code. I can't get windows or linux to recognize my phone. I've tried several drivers, but no luck getting my laptop recognize my phone. I have also tried couple of tutorials to solve this problem, but the main problem seems to be that I can't get my laptop to recognize my phone.
Is there anything I could do or should I just buy a new phone?

Hi Jutei,
What led to this bricking? Were you trying to install a ROM? Which ROM was it? Was it a wrong variant? Please be specific as to what you did to brick it..
Also, some people have seen success by installing this driver. Are you familiar with ADB?

Hi deathbytalkshow!
I ended up to this stage by rooting with this (http://forum.xda-developers.com/showthread.php?t=2448887) and trying to flash with this (http://forum.xda-developers.com/lg-g2/development-d802/rom-xenonhd-d802-t3036576).
First I wiped data and cache. Then rooted and it went trough with no problems. I tried to flash with this https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager. It booted to recovery and started flashing. Soon it said that flashing failed and after reboot I found myself in this bootloop.
Hope this helps someone to help me.

Try this:
1. Turn phone off.
2. Press POWER+VOL DOWN
3. When LG Logo appears, immediately release POWER+VOL and press and hold VOL UP+VOL DOWN

Hi, I tried this and got to the factory reset window. It started to do reset, but pretty soon it booted and went back to bootloop. So this didn't help. I'll try those ADB drivers today.

Hi, tried adb drivers, but no luck. My laptop still doesn't recognize my phone. USB gives power, but beside that windows doesn't seems to notice that my device is plugged. Is there anything else I could try?

so you didnt make a backup before flashing? what recovery did you flash? i bricked my phone with rom manager before and will never use it again but i had a backup and was still able to get it to eventually boot into twrp to restore.

Yeah, I was stupid enough not to backup. The recovery was the stock one. Is that where I went wrong? Should I've had custom recovery installed?

I turned usb-debugging was on before phone got bricked. I think the phone should be found somehow on computer. For example this fix (http://forum.xda-developers.com/showthread.php?p=48765620#post48765620) needs Linux to recognize the phone, but I can't even do that. I guess the problem here is that my phone won't enter the download mode. I'm going to try with couple of different computers when I get back home from my holidays.
I also found another fix to try. I have to drain the battery and after a little re-charge I should be able to enter the download mode. I'm trying this next.

yes thats where you made your mistake. that also makes me think download mode wont work period, but im not positive. im surprised rom manager even tried to flash anything without a recovery. thats why i dont use apps like that anymore because you wouldnt of been able to **** it up that bad on your own. so you said you tried the key combo to take you to the factory restore? if you didnt flash a recovery then i would think you could get that to work. did you look into lg's flash tool? maybe that will somehow read it. i remember seeing a post in the general forum about a way to take the phone apart and short the chip out but ive never had to actually read it so i couldnt tell you whats all involved. sorry bout your phone.

Well, I just got myself in the same boat.
The phone will show the LG Logo then the security error and shut down. When plugged in with a USB to the PC it will just reboot.
Nothing is showing in Device Manager either. I done the same in the stock recovery and I tried to Side load CM12 it failed and straight into this loop.
I got nothing now. I just done see how shorting circuits will fix the issue when it's just software. Absolute nightmare as the 12 months warranty has gone.
I tried to do a hard reset and I get the android man saying its working then it shuts down and starts the error again. I'm unable to get in the Download Mode either and I'm stuck
I don't know what to do now. The flash and Support tool will not recognize the phone.

jfletch86, I tried LG Flash Tool, but the problem is that it just says no devices found. Same problem with fix I linked, I can't do anything to my phone if my laptop doesn't find it. I'm beginnig to loose hope

Oh man, I'm sorry to hear that you are in the same boat. Symptoms are the same. It seems that we have bricked our phones pretty badly. Hopefully someone comes up with fix that works. Problem is that anyone wise enough to fix this isn't stupid enough to end up this stage.

I'm hoping the same too. I just don't know why it wont allow me to do anything.
I have a nexus 4 and I've never had a problem.
I am getting nothing when plugged into my PC and its like the phone is turning on and off in the boot loop and the lg symbol.
I get the hard reset menu but the computer still doesn't recognise.
I just feel sick at the moment !!
