Have you tried using another USB cable? Tried all USB ports? You might want to try on a friends PC. Look for someone with a 2.0 USB port.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
So you can flash kdz right? You have the drivers installed properly. How did your problem happen? If what said is correct "just keep restarting after flashing KDZ rom" you probably have a hardware issue, which is something I can't help you with.
[LG Optimus L9 P760, P765, P768, P769] Nathan.7118391:
Your flash didn't take, flash again. Get another kdz just in case.

Justso we are on the same sheet of music, your bootloader is unlocked and you flashed your original ROM back right?

Sent from my LG-P769(20F) using the xda-developers app. If I helped you please hit the "thanks" button.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
So you finally unlocked it, the best thing about unlocking is the "real" custom recovery (cwm or twrp). Plus you really don't need to use R&D Tool.

I have flashed 4.3 PACMAN from mateo it booted succesfuly, rom was working fine I did install apps from playstore and then decided to do restart. After doing restart it just freezed at LG logo (not the pacman one). I get into CWM and did format system, full factory reset, installed again 4.3. But this time I didn't manage to launch system. So I decided to flash Slimbean which was working fine, same issue. Then I decided to restore backup which I did before installing pacman 4.3 just in case something went wrong. And again it stopped at LG logo. So I tried to install via KDZ offline but it didn't detect my phone. So I did it online, it found my phone, downlaoded 600MB of KDZ file and then installed succesfuly but phone was just keeep restarting again again and over again. But this time at the 'second' lg screen.

Refering to your guide http://xdaforums.com/showpost.php?p=44578108&postcount=34 I managed to do 1-2 step. I do not have LG P2. Still I tried to install on LGE U2 or P760 and OMAP4430. Still when I connect phone, only TI Boards is ON. But still I managed to get same screen of CMD as you do on the last screen. http://i1363.photobucket.com/albums/r709/kuma82/Untitled7_zpse37712d3.png Take a look at my device manager: http://i.imgur.com/7dsjTeF.jpg.

I'm preparing a video to show how it looks like from my side.

edit: I think i managed to flash u-boot and x-loader. There was sending u-boot etc. and everything went succesfuly. But still It keeps restarting.

[LG Optimus L9 P760, P765, P768, P769] kuma82:
LG P2 becomes Android Phone -> Omap4430, so you won't see LG P2. It still sounds like a hardware problem. another thing You need to flash the u-boot for 20b, that u-boot you flashed is ice cream. Flash your custom recovery (cwm) with fastboot. Working with cwm or twrp (better) is easier to troubleshoot with. Pac should have not caused you any problems. It doesn't touch the x-loader or u-boot partitions.

---------- Post added at 05:05 AM ---------- Previous post was at 04:59 AM ----------

I had that constant rebooting problem once, when I flashed a modified boot.img. Right, don't use those imgs, it for p769 ice. Maybe your boot partition is bad, if it was the x or u (I think, not sure) you wouldn't be able to get into cwm.
[LG Optimus L9 P760, P765, P768, P769] maxver0:
I tried flashing recovery but it did not found device.

---------- Post added at 12:10 PM ---------- Previous post was at 12:07 PM ----------

I have choosen option 6 which is p760 - Flash JB xloader and uboot. So I guess it's fine. I should have now v20x 4.1.2 official rom which comes with emergency restoring software via LG support tool. I didn't flash any images. I just flashed 4.3 ROM and that's why it is strange. I think it might be hardware related. But I have never dropped him or something.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Sorry I forgot lelus updated his batch script, with jellybean. Did you place your custom recovery in the "your" folder.

Type this

fastboot flash recovery <the name of your recovery>

Example

fastboot flash recovery cwm.img
[LG Optimus L9 P760, P765, P768, P769] maxver0:
Thanks, it works. I now have my CWM back. But still i wont be able to boot my phone I think.

edit: After installing recovery my phone doesn't reboot anymore, now it is just image looping (bootloop i guess)
[LG Optimus L9 P760, P765, P768, P769] kuma82:
What kdz did you restore to your system?
[LG Optimus L9 P760, P765, P768, P769] maxver0:
It is v20b I suposse. Offline restore wasn't working so I have tried online restoring and it didn't said which version is being installed. When I had 4.3 installed and I connected, program said it is v20b version installed, so dunno. It was ~590MB KDZ.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Do you have any cwm backups (Stock cwm backup)?

The reason why is you can try putting the boot.img into the "your" folder and type

fastboot boot boot.img

Or try restoring a backup again. That's what I would try if I was in your shoes.
[LG Optimus L9 P760, P765, P768, P769] maxver0:
I have tried restoring full working SlimBean backup that I made before installing 4.3. And it did not work. I will try later restoring v20x backup as you said.
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
Almost there

:laugh: So I almost flashed it but it stopped on 4% on the update portion of the S/W update tool.

I found the LG P2 under other devices only when my phone was already in fastboot mode, I'm not sure why I couldn't find it before but that's beside the point.

I updated the driver to the one in Fastboot and I went through all the steps and got stuck at 4%.

I looked it up and this was because I didn't insert the modell.dll, again besides the point.

I'm not quite sure exactly how I got to my phone to go from fastboot to S/W mode the first time, (whether it was pressing 1 or 5 or 6) but I know I did it once so I should be able to do it again :highfive:
[LG Optimus L9 P760, P765, P768, P769] kuma82:
Alright progress :thumbup:

So did you install omap4430 driver into the LG P2? I'm sure you did ;)

Flash x & u for p7696 (ice) with fastboot.

Then turn off phone, hold vol + and enter the usb cable.

Afterwards, run offline flash

If your phone gets stuck during the flash, several times, well, you know what the problem is : (

Just keep your fingers crossed ;)
[LG Optimus L9 P760, P765, P768, P769] CoryKenzie:
No progress

ugh I've run into another problem.

Actually the same problem... running the start.bat, and than pressing 1, no longer automatically puts my phone into S/W mode.

I was only able to do this once and now when I run start.bat and press 5 it no longer runs xloader or uboot anymore. I'm so confused it was just working and now... nothing

Also when my phone is in Fastboot my computer doesn't recognize it anymore---Is that my problem?

BTW When it worked the first time S/W mode was also inverted at first. Is this suppose to happen?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
The inverted s/w is because you flashed the x & u for p760, and fastboot does not put your phone in s/w. You must have held the up button when you were putting the usb cable in.

Send me your info again in a pm, so I can help, I have my laptop this time.
[LG Optimus L9 P760, P765, P768, P769] maxver0:
I have found the issue. I have encoutered problems with restoring data with my 4.1.2 backup. So I took a look in mounts & storage found out that system and all other things besides external_sdcard was unmounted. So I just pressed mounts sdcard and system and everything(data,cache,system) has mounted besides 'sdcard'. And know everything works fine, even with 4.3 android. Some how it managed to unmount. Thanks for your help guys.
[LG Optimus L9 P760, P765, P768, P769] kuma82:
And that is the reason why I left cwm alone and switched to TWRP. I had a scare with cwm before. I couldn't restore data and un-mounting it through "mounts & storage" would not work (gave me an error). I had to get into adb and issue

umount /data

after that, i was able to restore my phone.

Switch to TWRP and you will be glad you did, plus backups & restoring seems way faster.

Glad you got your phone working :good:

I'm having trouble installing drivers if anyone can take a look at it with me, that would be great. I have an LG-P769 and a Windows 7 64 bit based PC. Any help is appreciated, thanks. :)

EDIT: I tried the show unknown devices thing and I got the 4430 device in the unknown devices tab, so I updated and successfully worked, but I don't get the other one. Does that mean something's wrong? Any help is appreciative like I said before. I got up to the part where it says waiting for devices... Well what's it waiting for? That's whats confusing me.

EDIT2: Eureka! I got fastboot installed, turns out I installed the ICS x and u, that's why it has the ?'s, but can I use adb reboot fastboot oem unlock now? Or do I still have to install the 20b to do that?
[LG Optimus L9 P760, P765, P768, P769] kuma82:
You can not use fastboot to unlock the bootloader, it's mostly used for recovery reasons. Those ??? are because it's not installed properly, or some other reason I don't know. I work nights and I'm about to hit the sack, so I won't be able to check your system out right now. You might want to leave that (fastboot) alone. Even the best can have a hard time messing with that stuff. If you read this thread you should be able to get it operating. I'm not trying to be mean or anything. Use lelus batch script, I made the instructions for that version. The original script doesn't play nice, and if you flash the wrong x or u, you won't be able to use your phone until you fix it.

Chromecast slowing my internet connection

Experiencing an issue kind of similar to the OP's. Basically while my Chromecast is plugged into the TV, even when not in use, it slows my internet connection. I normally get between 25mbps and 35 mbps down on a speed test and gaming as well as file downloads work great. As soon as I plug Chromecast in, my download speeds on a speed test drop to about 1.5mbps to 6mbps. All of a sudden online gaming is basically impossible due to ping spiking and downloading files becomes extremely slow. If I unplug the Chromecast my internet speeds return to normal. I don't know what Chromecast is doing, but something is taking it's toll on my network.

Rebooting the router (Linksys E1000 I believe) has down nothing to resolve the issue. Does anyone know what could be causing this? Is there a way to make Chromecast hibernate or something when it's not in use? Any information about what could be causing the issue or things to try would be helpful. Thank you
[Google Chromecast] Nemoth:
Corrected the issue

I was able to fix the issue. Turns out my Cable Modem has a built in router that my computer was plugged into. I also have a linksys (wireless) router that is connected here. The chromecast is connected to the linksys router. I unplugged my computer from the cable modem (router) and plugged them into the same router as the Chromecast (Linksys). This appears to have fixed the issue. Someone that is better with this stuff could probably explain why, but I just wanted to follow up.
[Google Chromecast] sti3:
Totally!

I had this problem too. I have a Chromecast, AppleTV, GoogleTV and Ouya all right next to each other, with the Chromecast in an "always on" state. Ever since plugging in the Chromecast, network performance on the AppleTV and GoogleTV has been unusably slow. Even VNCing into my desktop PC, which is hard-wired into my cable modem, was slowed down.

I unplugged the power on the Chromecast last night, rebooted the AppleTV and GoogleTV and voila they work wonderfully. Network performance on other connected devices seems to be much better as well.

Would having several wifi devices in close physical proximity be the cause, or is it more likely Chromecast's need to be "discoverable"?

FWIW my wireless router is an Xfinity modem.

[Google Chromecast] bhiga:
Can you describe what happens in a little more detail?

Does your network get slow, does your Internet get slow, do your devices suddenly say there is no wireless network? Something else??

"Unusable" can mean a lot of things. :)

My internet access on other devices becomes very slow to the point of being unusable if the Chromecast is plugged in.

Hmm, Google says your RTN56U is compatible but to contact ASUS for assistance which I'm guessing means ASUS might have an beta or pre-release firmware that fixes the issue.

[Google Chromecast] wilsonbrett85:
I'm having this same issue. I'm using an Asus rtn16 with tomato firmware by shibby. Quite frankly it's ridiculous that this is a problem for chromecast. My router is a newer model and it should be supported. My roku 3 is able to stream just fine off my WIFI. All I've been able to deduce thus far is that when casting, the wireless interface of my router seems to get ddosed in some way because when pinging the router wirelessly from other devices, the pings skyrocket up to 1000ms and it causes some packet loss. Ends up making the chromecast stream really badly and of course my other devices slow down. When pinging the router through a wired connection during this time, the pings are sub 1ms. So it seems that the chromecast wreaks havoc on the wireless interface for whatever reason. As I said before, no other devices in my home cause the same symptoms. I may try to see what I can gleam from sniffing the network with my alfa usb WIFI adapter which is able to capture everything going across the air in promiscuous mode. I'm not sure if a lower level wireless spectrum analyzer would be necessary but let's hope not. Or let's just hope Google gets this sorted! I realize that some have fixed this by switch routers, but I don't see that as an acceptable solution since no other devices have issues with my router.
[Google Chromecast] bhiga:
Roku and Chromecast work in very different ways and therefore use the network in much different ways. Chromecast has a discovery protocol that Chromecast-enabled applications use to find Chromecasts on the network. This involves multicast packets, and while most routers handle and allow multicast just fine, some either are stupid/flawed or are shipped with "secured" default settings that block multicast traffic.

After discovery

What applications and content are you casting from?
[Google Chromecast] wilsonbrett85:
Tried youtube, tab casting, and plex.

Youtube barely gets through a video. Tab casting works for a couple seconds, then chokes and loses the connection. Plex buffers every 5 seconds. I actually do notice ping rises to around 500ms when using plex on my galaxy note 8, when the client fetches chunks of video every 10 seconds or so from the server. i noticed that this happens over tcp, whereas tab casting sends a udp flood. but I'm not really sure what is 'normal' as far as the ping going up when the wifi is being used to capacity. I can imagine that saturating the network would do that. I know that plex will pull data in chunks as fast as it can. So that saturates the wifi for about a second or two for every chunk. But I guess for whatever reason, chromecast saturates it even more. Not sure if its because its udp or what, and I don't really know why that would make any difference.

So, streaming with anything else is ok, on both G & N modes, causing ping to go to around 500ms.

When streaming to CC, on both modes, ping can hit 3000ms at times and total packet loss.

I'll see if playing with any of the advanced wifi settings in the router can fix it.
[Google Chromecast] Asphyx:
