Battery is charged, wipe data is complicated because i didnt come in the rescue mode or cwm, only in S/W upgrade...
Ok now i'm in the Android system recovery, but it does not always work...

Take the back off, pull the battery. Put it all back, turn on the phone holding the POWER and the -VOL to boot into recovery.
Did you fix the permissions..?

[Q] LG990 won't boot.

I installed a rom called Eaglesblood from ROM Manager.
When it was all installed, the phone just loops and won't start. The only thing that is showing is the Eaglesblood logo. I tried to boot ROM Manager, but it wont start since the LG logo is not showing.
Is there anything I can do?
One more thing, I tried to connect it to the computer and it is charing, but it does not show as any device on the computer though.
You must wipe your phone before installing a new rom, otherwise you can get bootloops, try it good luck

search around, there's a few very good guides on this and other forums.
You must reboot in cwm and there you can wipe the phone... in option advanced are mire wipe option, best way to install a custom rom is making a fullwipe.. whatch in xda there are many guides for this.

I tried to access the CWM by holding the Power and -Vol on the phone. The phone just boot up and doesn't even go into the cwm. The Eaglesblood logo just repeats all over.
I can take pictures if you like, if it is easier to understand.
Is there anyway to access the phone by USB? I can't even find it on the PC when I plug it in, it just charges itself

I gave this a try before, in like 10 minutes. It doesn't do anything, just the EaglesBlood logo is flashing in a loop.
Hold down the volume down key and the power button, this have to work..

If you are unable to recover your phone you can always use NVflash. It will flash one of the first Froyo versions on your phone. Then you can root it, install ClockworkMod and install any ROM you like.

It's low level flashing so use it only when there is no other option.

Thanks! But I still have an error trying to connect my phone to the computer. The USB is charing the phone, but the computer won't recognize the device. It doesn't even popup anything.
I have windows 8 on my desktop, and I tried to plug it in the laptop aswell, but it doesn't do anything. And yes, I have the LG drivers installed already.
If you remove battery and you push vol down key and power button and you connect to usb then you get into recovery mode?

No, it doesn't. The LG logo is just flashing then it turns black and repeats itself like that.
However, i tried only to hold down the vol-down button and plugged the USB in and then it starts something saying:
"S/W Upgrade please wait while upgrading..." but it does not show up on the PC as if it was connected.
Yes, so try to reflash cwm.. look at the guids in the section android development..

I'm very thankful for linking me this, but the problem still exist that I can't find my device on Windows. If i remember correctly, the USB connection to the phone stoped to work when I fixed root access to the phone and the CWM.
Is there anything I can do to fix this USB connection issue?
Try this, you can get to the stock via s/w upgrade and smartflash this must work, there is a completr tutorial how to get on stock via smartflash. I hope i can help

His cable works, otherwise he can't get to s/w mode.. try the tutorial with smartflash i send you in the last post

bricked, doesn't boot anymore

Ok, accedently did a format sdcard (the internal) and now the screen stays black.
Tried the usual keys, but it doesn't do anything.
Anyone got a suggestion?
Expect sending it to samsung.
AW: bricked, doesn't boot anymore
An sdcard wipe shouldnt break the phone at all cause it will never touch the system...
Can you get into recovery or download mode?

There's no way you can brick a phone if sd card is formatted. Try to enter recovery/download mode.

Take your battery out for like 5 minutes then put it back in and try to boot or try to go to download mode

- Charge phone
While not succesfull
- remove the battery
- try to go to download mode (see: http://forum.xda-developers.com/wiki/Samsung_Galaxy_S_Plus/GT-I9001#Download_Mode)
end While
next time check the recovery also and flash stable recovery.
It helps a lot to prevent many unknown things.
Happy flashing.

[Q] Samsung Galaxy Mini GT-S5570B died after Cyanogenmod 7.2.

I was using that rom: http://forum.xda-developers.com/showthread.php?t=2085347, and after install Cyanogenmod 7.2 (http://download.cyanogenmod.org/?type=stable&device=tass) on my phone, i click "Reboot system now" on recovery mode (Clockworkmod Recovery 5.0.2.8), and they just dont turned ON again, and now, NOTHING WORKS.
I tried to remove battery, put battery, i tried all the keys combo on the phone, and they even turn on the display, only the mode thats working is the RAMDump (Arm9), but still with the screen off. How i now thats rampdum mode is working? I connect the phone on my pc through the USB and pressed Home Button + Power Button + Volume UP Button and my PC recognize him, but i think there are nothing i could do with ramdump mode. I saw that post http://forum.xda-developers.com/showthread.php?t=1688137, but my device is different and maybe theres something more wrong, and i don't know...
Anyway, THANK YOU GUYS. Hugs!

Is it a patched v20 rom that you flashed? Flash again using SmartFlash and once the phone boots, it will take you to the CWM recovery screen and then do a factory reset and wipe Dalvik cache. Then reboot your phone and it will be just fine. BTW read the "Noob how to" section in the Q&A it helped me a lot.

The patched v20 bin/fls files should work for you. If not, try the hard reset unbricking method. You're welcome.
