Android problems after trying to unlock BL - LG Optimus L9 P760, P765, P768, P769

So after messing around with fastboot with a working phone, I think what I did was flashed both ics and jb uboot and xloader, and when I turned my phone on it had the same weird fastboot screen striping at the bottom. They are really strange problems that aren't necessarily phone breaking but unbearably annoying.
After a couple of uses in the messaging app, it hangs at startup,usb debugging doesn't connect to pc, if i use a lock screen besides instant unlock the screen stays black when you try to unlock it, and finally lots of apps seemingly randomly crash and are pretty slow. I tried flashing stock kdzs', and resetting with cwm. All seem to work at first but the phone degrades after about a day. There really isn't any error reports I can think of but if someone knows of one to help me, or help someone else help me solve this problem that'd be great.

flash the ics x and u and do a kdz flash it will fix it same thing happened to me before i unlocked mine

Alright I'll try it today. Thanks for the reply!

Fingers crossed...
Well usb debugging isn't connecting but that could be a driver problem. The lock screen so far seems to be working. Again thanks for the reply thasilenthacker.

Sigh, Nope after about 3 hours the screen started screwing up again. If anyone knows how to somehow completely reset it or something, i'm really hoping it's not a hardware problem.

Phone won't unlock, what could be the problem?

Hi everyone, currently have a situation with my HTC HD2. I have the Energy Sense Rom and I just noticed a couple days ago when I try to slide my phone to unlock it, it won't slide at all. Like it won't recognize my finger and only way for me to do anything is take out the battery and put it back in.
Anybody have any idea how this could happen? Is the phone pretty much dying? It gets damn annoying when someone texts me and I can't slide the button over to unlock the phone. Sometimes I just gotta give it time then it would work but who wants to do that? Any help would be appreciated. Thanks!

Does this happen in any other applications apart from the lockscreen ?
Sometimes when it does unlock, I won't be able to pick any icon on the screen. Literally the whole screen wouldn't do anything at all. I can't push the start button, I can't click on opera, all I could do is lock up the phone again.
Gets so annoying! I'm gonna try to upgrade the custom rom and see if it does anything.
hate to say it but i think you are going to need to return your phone. likely hardware. this happened to me; hard keys worked but screen was flakey and then stopped worked. by chance, have you used android?

Never used android so I don't think it's android related at all. Just happened out of no where.

[Q] Problem, Stuck in Black screen doesn't wake up

Hello!
Well... I have this phone since yesterday... I plugged to the computer with Kies, and well, a update was available... now the phone have Froyo and the aesthetics changed completely, it looks awesome.
But, the phone have this ANNOYING problem that, after using it... like 5~10 minutes of no activity, when I try to use the phone again it doesnt work... doesn't respond to any button, I have to take off the battery in order to restart it and that over and over again...
I've realized also that this happens when I'm using wifi, if I left the phone with wifi on this happens, without wifi seems to work fine.
Somebody have any clue what could be? there's little information about this issue in the internet...
I think I'm going to return it but I want to try everything I can do (without voiding the warranty) since the phone was perfect for what I wanted.
Thanks in advance!
Hey. I got the same problem here. It only happened a few times when I just had froyo that came stock on my galaxy 5 but I recently installed cyanogenmod 7 and now its happening everytime I put my phone down.
So I'm guessing it may be directly related to what rom is installed? I've heard about it happening a bit to people who have 2.1 installed to.
I dont know too much but it seems the only fix is to take out battery and turn on.
Sorry I can't help more. I hope somebody knows a bit more than me on this.
Think this is called something like the 'wifi sleep of death', something to do with the rom. i'd try change the rom and see if it still occurs
Thanks for the hints tho!, but I returned the phone... it seems that is a bug related to the update of the phone, since I know that with the out of the box 2.1 version it doesn't have that issue...
You know, the mobile carriers also do weird stuff to the roms... -__-

problem with touch screen

I have a big problem!! I flashed the new minicm7 rom and it was running perfectly till now, that my touch screen went crazy!! it scroll down all the time, no matter where I pressed, it presses by it self at the bottom of the screen... sometimes it works a little bit, and then my problem comes back again... I tried to reflash the rom, wipin and factory reset, but I got the same problem even in the lock screen...
Could it be hardware problem? My phone didn't suffer a fall or something like that... it's very annoying!!
has anyone experienced that?? what should I do? should I try to reppair with SEUS? in that case how?? and if the problem persists what should I do to leave it exactly in the stock way in case I had to send it to reppair?? because I still have warranty... please help me!! I'm desperated!!!
thanks if you please help me!!
i'm sure there must be someone who can help me! please
I only get this problem if my phone is on charge. But other than that its ok.

I've experienced this but on the Cyanocream Sandwich. It fixed itself upon reboot. never had the problem since. might not work in your case, but give it a shot
thx you 2 for your advices but nothing seems to work. i flashed minicm2.1.4 after 2.1.5 and the problem persists... when I was desperated I tried update with pc companion and it seemed to work but the problem came back. what its amazing is that its not happening continously but randomly and if it happens I block and unblock the screen and it works for a while...
when the problem appears what i experienced its exactly like this: if i watch web pages and i scroll down my screen goes to the top inmediately and i cannot keep on scrolling down,or if im writing if i press a letter one different below is pressed instead...or watching my apps if i go left it goes down crazy as if it wanted to go beyond the bottom of the screen...
if anyone else could help i would appreciate it,if not i'll have to send it to repair for free because its still on guarantee... in that case how should i do to leave my phone in the exactly stock way for the technicals not to see its rooted or unlocked bootloader...
thank you in advance!
As you said you have to use SEUS to return to stock FW. Just turn off your phone and then follow the steps on the computer. When it comes to relocking the bootloader, I cant help you as I have not tried to relock mine yet.
Good luck

[Q] Screen Problems following ICS Update

Hey guys, so I just updated my att galaxy s2 via kies to android ICS however after that I've ran into some problems.
After updating however I encountered a period where the screen went black and the phone kinda just died on me. After restarting I began to encounter some problems. For some reason, whenever the phone goes to sleep and and then wakes up, my screen gets flipped upside down and the screen gets really bright. Despite that, I still have to press the screen like usual. Which means that if the call button is at the top after flipping, I still have to press the bottom of my screen. Also the screen isn't perfectly flipped and there is space above the top bar.
However, the phone does work fine on bootup, and only fails after it sleeps. Also, very recently my phone just went through a screen repair after the screen cracked under the glass, but otherwise that I have no clue what's going on.
Is this just a poor repair and a hardware problem or is their another problem here?
Also I've tried a factory reset and that didn't help.
Thanks for any help you can give.
(Hopefully I got the right board)

considering this board is all about CUSTOMIZING devices... I dunno about that. Maybe try the AT&T site?
Maybe one of our divas will be kind enough to help anyway.
Yes, I mean divas, also referred to around here as devs. I <3 u all!

Yeah I kinda got that gist =P
but, after searching through the web, there weren't really a lot of sites that I came across detailing about my problem, but this was one of the sites that came up a lot so I was just hoping if anybody, just anybody could help me out with this.

There are alot of things that could go wrong when flashing ROMs.
All of the custom ROMs here have built in safeguards which allow users to recover from issues involved with flashing. The same cannot be said about stock builds.
Unfortunately, your options are limited if you're going to stay stock. You can either try a factory reset and re-installing the update via KIES or you can call AT&T. That's pretty much it.
Personally, i'd Mobile Odin a rooted package with CWM and start flashing some of the wonderful work the developers have graciously allowed us to partake.

OP, I agree with the sentiment here, but you can't use mobile odin until your are already rooted. One option you could follow the guide linked in my signature to root the phone and go from there.
My personal suggest is that if you're running stock ROM, updating an official stock ROM and having problem, I call the provider for help.
My download and install went fine but I incounterd some unusual problems afterwards. My phone doesn't always keep a data signal while browsing the internet and a phone reboot makes it return. Setting browsers home to Google instead of default AT&T doesn't stick. I also had few dropped calls and very low signal bars in status bar at my house which gingerbread gave me full ones.
same here

Did you managed to fix it?
Any help would be greatly appreciated

Atrix stopped working

Hello,
I having big problem on my Atrix. Out of nowhere he stopped working, I've tried everything - taking out the battery (which had 40% when it happened), sim card, connecting to original wall charger. Nothing. I'm pressing the power on button and it doesn't turn on.
:crying:
If anybody have any idea, I begging you to help me.
Thank you and good day.
P.S. I forgot to mention that the phone is with me only a month, worked perfectly
Hello again,
I would like to add something that I noticed about the phone and maybe someone could use it to get ahold of the problem. Every now and then (few hours mostly but sometimes minutes) the phone turn on, get past the boot sequence but then get stuck and shut off again.
Last time I connected the phone to the pc, the pc recognize that there is a device but not past MOT ADB device to the MB860 like it did before. This time it got stuck in the "UNLOCKED" screen and shut off again.
I will be hugely thankful for someone who can point to the problem and even find way to fix the problem.
Did you install any custom rom?
