Doesn't boot after Recovery install - LG Optimus 4X HD

Hello,
I am having a problem, after rooting / unlocking, i have tried to install recovery using method given here: http://forum.xda-developers.com/showthread.php?t=1826378
I have boot the phone, install this recovery... boot recovery - then the problem came... it starts booting, LG logo is finished, start animation and stops... need to remove battery. The problem is that my version was 4.1.2. which ain't supported by this methog which i have seen to late.
I have tried to do everything LG User Support Tool, LG FlashTool, etc. - nothing helps.
Any idea? Is there a way to unbrick the phone - or it's finished? I have no ideas anymore.
Thank you in advance.

P990 Probably wrong flash

Hello everyone
Recently I need to flash my ROM to official ROM - BIN_LGP990AT-00-V10c-EUR-XX-APR-16-2011+0 by SmartFlashTool for p990. Everything was successfully done and everything worked fine, then I rooted my mobile by SuperOneClickv2.3.2-ShortFuse. Again, everything was done well, but the program asked me if I want to install BusyBox, I chose YES, but I think that I hadn't done it. Because then I want to start/boot my android and nothing happened, just LG logo and then nothing only black screen (as like been the system was stuck), no boot logo, nothing even though I wait to boot about 10 minutes. I diceded to try flash my mobile again by SmartFlashTool, but didn't work again. I done everything right, but still 3 sec LG logo then nothing just black screen. I also tryed to get to the Recovery Mod but still no response.
Please VERY PLEASE, WHAT CAN I DO NOW??? HOW CAN I FLASH SOME NEW ROM WITHOUT SmartFlashTool and Recovery Mode or how can i FIX this problem?
P.S.:SORRY FOR MY ENGLISH

[Q] [HELP] My LG P970 is stucked on LG Screen

Hello guys, I am new at this forum but I have been reading this for years, but just now I needed to post something.
I have a LG Optimus Black P970 and it's now Bricked, I will try to explain it.
The samrphone was from my father and he gave it to me already bricked, he was using Stock ROM from VIVO (Brazil) Android 2.2 (Froyo) when It bricked, then I asked for him the smartphone and I tryed to use the SmartFlash to unbrick it and put the CWM Recovery as I used to use. The P970 didn't boot at CWM Recovery automatically as was supposed to, but after few hours pressing Vol - + Home Key and Power Button I was successed. Then I flashed Zeus ROM and everything went fine, the P970 was UNBRICKED!. Ok, I gave it to my sister-in-law and she was using it untill tomorrow... Then she asked me to unclock the network so she could use every SIM Card, for this I had to flash another ROM, I asked the P970 to boot into CWM Recovery (holding power button, reboot>reboot recovery) and now It is stucked on LG logo again. I tryed to flash 5 Stock Firmwares, 10A, 20B, 30A, 30B, etc but none worked. I really need it unbricked. I have been searching tought internet but every tutorial didn't work.
Please some one help me, I can't lose this smartphone. Oh, one more thing, I can boot into S/W Upgrade normally...
Thanks!
So you have tried using the smartflasher?? If so then it should be fully fixed... give it sometime to boot though as when I'd restored mine it took like 5 mins top for it to get into the main menu..

Yes, I did it several times and didn't fix the bootloop.
Is there a way that I can wipe data/factory reset thought a computer? Because maybe It could fix my phone, but I cant boot, it's still stucked. I really need help here
any help?
Hi MuriLOCO, I had bricked my p970 before and flashing via flash tool did the job.
You can try flashing it via S/W upgrade.
Go to LG website and download the updater so you could flash it with S/W update.
Hope that helps.

[Q] LG G Flex D950 soft bricked CWM boot loop, no DM

I'm new to the development side of Android and I bought a ROOTED phone from a Co-worker. Well my phone tried to do a software update and the phone is stuck in a CWM boot loop. Me not being familiar with CWM or ROOT, I pressed the factory reset button in CWM. Now I am unable to fix it. I have tried ADB sideload to load ROMS to the phone. They will say they are installed but then it will just go right back to CWM. I am trying the LG flash tool now but my phone will not go into download mode. Can anyone help me, please. I love this phone....

Can you get into clockwork mod without it looping
If not try command
Adb reboot recovery
Chances are previous owner has some Roms saved on the SD card
In the download folder
Keep in mind Roms are carrier specific on this phone
Yes it boots into CWM recovery and I accidentally wiped everything. I am trying to use the LG flash tool but it will not even go to download mode....
In recovery factory reset clear your cache and dalvic
And try sideload again,if it doesn't work try pushing the file with adb
If you can't get that pm me and I'll troubleshoot with you.
D950 on LG logo
I have a D950 only boots to the LG logo. I rooted the phone and then tried to install CWM. I didn't know about Freedom Flex then, so i used a forum post to try and do it. I successfully got CWM on the phone, but now it won't boot past the LG logo (also boots to CWM, I think it'll go into download mode). I'm not sure if I did any of it correctly, but I've tried CWM, ADB, LG Flash Tool, Odin, etc to somehow get the phone working again to no avail. I'm not even sure if anything can connect/detect the phone. If there's nothing I can do then fine, but if anyone can help/try to help please do. It was a nice phone an i'd love to have it working again, its been so long.

[solved] Can't enter recovery after 'format system' in CWM

Hey guys,
I may just have the most stupid thing I could possibly do. I've got a soft-rooted Xperia SP (TowelRoot) and opened CWM Recovery to try to install Cyanogenmod. It cited I had to 'format system' and I rebooted the phone thereafter. Now it's stuck on the Sony Logo and I can't get it into recovery anymore. Even by force-rebooting via the hardware button on the back I can reboot the phone, but it stucks at the sony logo.
Please help, I haven't got a clue..
Update: I can get into fastboot mode. However, my bootloader is still locked.

when you wipe data the cmw is gone....best thing to do now is to flash stock ftf ROM via flashtool ...go here and panic
Well, I'm glad all android phones have a fast boot mode, which I was used to with my previous HTC One X. I Quickly fast boot flashed a new boot.img and I had CWM back on. Then I installed CyanogenMod and I was done. Pretty easy in fact.

I know I have done few things wrong in confusion, but realized later on. It is H811 TMO model for sure.
I did select refurbished while using LG UP
My phone is not completely dead.
Pressing power button it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
I am unable to enter download mode, it responds but freeze before entering download showing 4 blue dots.
I am able to enter recovery but I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.
No charging, Device Manager shows nothing.
Is there a way to recover??
I am not sure, If this is some hardware issue or emmc fault , Please help me on this..
