P760 Bootloop problem - LG Optimus L9 P760, P765, P768, P769

I've unlocked bootloader, tried to flash new rom and now i got stuck at rom's logo. I just can wait forever and nothing happenes.
Tried to wipe, and even format everything (data/cache/system) and nothing.
Tried CM10.1 i a zip, ExperiencedStock as a backup, and even my own backup i've made before.
Everytime i got stuck at rom's logo.
I dont know how to put my phone in SW Update mode since i got CWM, and every time CWM starts and i cant flash it with LG support tool because the program doesnt see my phone.
Did anyone had this problem?
Maybe stock Recovery.img would help? Anyone could give me it? I can try to flash it again with fastboot mode.
Or any other sugesstions?

Try hard/factory reset ; turn off your phone , hold vol- & home ,press and hold power for couple of seconds

With vol-,home & power it also boots to CWM :/

Have you trying to restore stock rom via Cwm? You can download fresh one from our forum.
Go to advanced and clear dalvik cache it might help

Yes, tried fresh CWM backups also.
But finally i solved this problem
Dont know why, but when i formatted internal sd, rom booted with no problems.
Firtstly i didnt want to format internal sd because there was my backup in case something goes wrong.
But it went wrong, so i had nothing to loose
So if anybody will have this problem then format everything (cache/data/system/internal_sd, wipe Dalvik), then restore backup or install zip from sd_ext.
ExperiencedStockFinal booted ok, backup made on sd_ext also.
Will now try to install CM10.1, and maybe i'll investigate why i have this bootloop bug on my phone.

[Q] Can't remove installed software and can't use odin

Ok so I'm fairly new to the rooting scene, and these forums, but so far everything has been pretty good, except for one small problem. I installed a custom boot logo, and afterwards my phone was lagging a bit. I contacted the boot logo programmer, with no response, so I decided to wipe my system and use the backup from right before I installed the custom boot logo. Unfortunately, the boot logo has not changed, and my phone 'fails' whenever I try to flash something from Odin. Anyone know what to do in this situation.
If you want to do a full wipe of you device,cos it sounds like tha boot logo is corrupt,then boot to recovery and wipe cache partition and dalvik cache.then go to "storage and mounts" and format system,data and cache.Select "Go Back" and factory reset your phone and reboot.If it doesnt go past the boot logo after 1min then pull the battery,put it back in and turn it back on.Its a pain in the arse but it will completely clean up your device and if you where rooted you will need to probably reroot but berfore hand plug in your phone to your PC so it gets recognized again.
EDIT:Just incase,first of all download titanium backup from the market and backup your apps!!!!

You need to wipe usb storage, sd card, then put phone in download mode, flash stock ROM using Odin. You need to fully wipe everything.

I've trying reflashing the stock ROM and kernel; however, it gives me a FAIL and says can't open the serial (COM) port.
I have solved the problem by closing Samsung Kies and wiping the system, thanks for all the help offered.

[Q] Bricked?

Hi,
yesterday I tried to upgrade to CM7.2 from a nightly. As I've been doing, I put the .zip in the sdcard and flashed it with ROM Manager (wiping everything). After flashing it, my phone stucked at HTC white screen and there is no way to switch it on, it stays at this screen all the time.
For my disgrace, it's S-ON, so I can't boot into recovery and restore anything. I've tried to restore a nandroid with fastboot and it doesnt't work (says "Failed (remote: signature verify fail)").
Any ideas? It's definetly bricked? Is there any hope of repairing it?
Thanks in advance (and please forgive my poor english xD)

What do you mean you cant boot into recovery because you are S-ON?
All you need to do is put the recovery file other wise known as flakeflash "UPDATE.ZIP" into the root of the SDcard, turn off your phone (Pull Battery), then press the down button and power button together, wait for the phone to do its stuff, then select recovery in the menu, the phone will reboot into red exclamation mark, press volume up and power, it will then go into stock recovery menu and will then look for the "UPDATE.ZIP" if all is well you should then go into the fakeflash version of clockworkmod recovery.
Does it boot when USB cable is plugged in (soft usb brick)?

Thank you very much, now I can boot into cwm, but I'm having some troubles when trying to flash CM7.2 (or even trying to restore any nandroid backup).
First, when I try to install CM7.2, it does it very fast, without showing any error, but when I restart the phone it gets stuck again on HTC screen.
Then I try to restore a nandroid backup but it doesn't find boot.img, system.img and data.img, skips all steps and restores nothing.
My last shot, try to install the last nightly I used, fails at the same point as when I try it with CM7.2.
I don't know what else can I do, any ideas? I hope there's still any chance for my Legend (and again forgive my bad english xD)
A few points, make sure the rom zip file you are going to flash is not corrupt or incomplete.
Boot into cwm recovery,
Make sure to format the boot, system, data, cache & ext, it wouldn't hurt to delete the dalvik cache too before flashing new Rom. Just remember NOT TO FORMAT SD card.
Using this method I have always been able to flash a new Rom.

Prepare a new SD card in your PC (FAT32), put UPDATE.ZIP on it and a stock ROM, reboot into recovery, wipe all you can (factory settings) and flash the stock ROM, see if that works. If so, you could try to flash a custom ROM.
That is what I would try...
I'm too.
I can't up CookROm by Rom Manager,
but when i use ClockworkMod recovery, its OK

Your phone is not bricked. When the phone is stuck on the droid eye, hold the power button and the volume down key at the same time until it reboots. This will get you into bootloader mode. Press the volume down key to highlight recovery and press the power button to enter it. Once you're in recovery go ahead and restore a backup or reflash something new. Either way make sure to do a full wipe.

thats what i did i restored my backup and this is what happens. and i cannot push any files over to the phone because usb debugging is not enabled so there is no communication between the phone and computer at all
boot into recovery then use "adb push <path to rom> /mnt/sdcard/" to put a rom on the sd then install. Make sure you use a boot.img that came with the rom if it has one as it may cause problems if you don't.
Edit: you will need another rom for this and I would recommend reflashing a boot.img

USB debugging has nothing to do with ADB in recovery, recovery basically has its own kernel and ADB is always enabled. Are you saying ADB doesn't work in recovery? If so, it is probably a driver problem with your computer. Also, some phones randomly get corrupt /data/ partitions (mine used to get them until I started using DSB's stock kernel with system write) and the only way to fix it is to do a factory reset or restore a backup. This might be what happened to you. If so just do a factory restore and see if it will boot.
Perhaps reflashing recovery? Worth a try if ur still having problems, also try installing then uninstalling htcs sync app.

Reboot to TWRP and wipe your System, Data, Dalvik and Cache... Then Boot to Download mode and flash your phone's proper firmware using Odin.. Make sure you have a backup of your installed Apps and their Data..
Hope this helps you

Thanks alot man!! I flashed stock as you said and everything went back to normal. Good thing I had 3 different types of backup so I didn't lose any data.

Stuck on Bootlogo - no backup?

Hello everyone.
So I was trying to install CarbonRom (https://forum.xda-developers.com/htc-one-x2/orig-development/rom-carbonrom-5-1-1-t3287099) but I have failed somehow. I had the problem of stucking on boot logo, so I went after the advice to boot boot.img via fastboot. I did that and well... nothing. It would be nothing if I didn't wiped data as in instruction (or I misunderstood something), which deleted all the data, even my backup of last stable rom I used.
Any advice?
Wipe system AND data again, you can flash the correct boot.img and tada should work and don't forget to reflash a rom.

When I want to turn off phone from recovery after wiping system and data it says I have No OS installed. Won't I just f**k up my phone much more by doing that?
