[Q] Drivers Problem With Boot-Loop Phone! - GT540 Optimus Android Development

On My XP computer i was able to flash mine and my fiancées phone's in the correct way then when i went to do my friend's in the exact same way it KDZ updater crashed near the end so now the phone is stuck in boot loop. All i can get up on it now is DOWNLOAD MODE but every time i try 2 re-flash it the computer loses connection with it. I've tried every possible way available here and over at Modaco but haven't had any joy. Does anyone have any idea what could possibly be wrong?
I haven't a clue how i got it working but think it was somewhere along the line's of taking everything out of the phone and plugging the USB in so it turned on itself. Instead of the phone booting up it came up showing a pic of the phone to show to put the back cover back on and was able to get the drivers to work then. Hopefully this will help[ other ppl!

try to set it in download mode and reflash

Hey thanks for the reply but i had already edited the bottom of the post to say how i got round it so hopefully it would help others. Thx anyway.

KAIS130 unabled to communicate with PC

Hello everyone,
I am having problems to connect my Tilt to my pc.
First of all, when I power it on, the screen goes black and says "smart mobility" .. so far so good; but after a few seconds it starts again and loops endlessly. At that point the only way to power it down it to take the battery off.
I installed the drivers manually (Vista) and hoped to be able to use mmty (after pressing "camera button" and " power button") but I never managed to get a connection.
Does anyone have any ideas on how to get my HTC tilt back to a running state?
Sooo, this only happens when connected to the PC or all the time?
It happens all the time even when not connected to PC
I forgot the most important part ... this happend since I tried to update windows mobile (source downloaded from HTC official site).
Hard reset?
if you mean holding down both green and red headset button+pressing the reset button, yes I've tried that but didn't change anything.
It went through a whole process and nothing changed? Try to flash back to an oem rom. (seems to be the new popular suggestion).
ok but how can you do that if you can't get to connect it to a PC via usb?
By following the proper steps to flash a phone either by usb or SD card.
The phone doesn't need to be fully booted to flash.
Ok, that's good news for thanks.
If by any chance you have a link to a tuto in order to do that you're welcome. Otherwise I'll google it and get back to you to keep you posted.
It's all in the sticky

Thanks I shall try to night
Thank you for your time. I finally managed to do it and my HTC is back to running.
The only problem I had trouble to solve (if it can be of any help to anyone) is that I had to unrar the *.exe which I didn't could be done.
Thanks again

[Q] Phone won't display home screen.

So I was looking through the topics in this part of the forum today, and I saw "[Q] What is causing "Communication Failed" error?" (It won't let me post the link to it?) I followed the link in that topic and did what that guy said would help, and after doing that I restarted my phone. It did all of the startup animations correctly, I can still access the recovery menu out of it, but when I get past the startup animations, I'm just greeted with a black screen. The buttons on the bottom of the phone are lit up, but the screen gives no response. I can't turn it off without taking out the battery, and that doesn't help. If possible I'd like to try to fix this without sending my phone in, or without deleting the user data. Any fixes for this?
I would try re-downloading the ROM you want to use and then re-install it. But maybe there's a better fix, that's just what I've done whenever I encounter something strange.

I can't exactly put anything onto my phone with this problem. I can't access the screen at all past the startup animations. It's just black.
Not Bricked!
You have a few options as it seems your phone is "on" and should be recognized by your computer still.
What was it you were doing to the phone before it started doing this behavior.. wasn't quite clear on that....
If it was a mod to change your framework-res.apk. You can find the "stock" one in the ROM you originally downloaded and revert back to stock by doing an ADB Push to your /system/media folder.
Or... you will need to flash your phone back to stock - which means you will need to go here and download Odin and run it.
Always helps to have that "plan b". Bottom line though - your phone isn't bricked and you should be able to restore it and continue on. But... please note that ODIN will wipe your phone and anything you had on it will go bye bye.

I followed the advice on how to fix that problem in the second post in that topic. When I restarted my phone the screen just ended up going black. I'm going to try that Odin thing, I hope it works.
e. It's kinda annoying how I can't post links.
Ok Edit again, I've tried the Odin thing, and it just isn't working. Now whenever I try to put my Simcard back in, It doesn't even do the startup things, it just goes to that Phone Caution symbol PC picture thing. I'm worried that I'd have to go get a replacement.
Can you please provide us with a list of everything you have done to your phone and how you tried to use Odin? That will help us help you. Please be specific, this will get you the help you need. I read the link, did you use ADB or the first method in that thread? Sounds like you messed up while trying to fix your device manager. I am not sure how it is you tried to use Odin, try using a rear usb port, Odin can be a pain, make sure you have the drivers installed.
Ok, Here's a list of what I've done to my phone over the past few days.
1. I rooted it.
2. I kinda sorta half-assed the process of allowing me to put on Non-Market apps onto my phone, I made it so that the settings.db file had the permissions all set up, but I never replaced the first settings.db file. (It's just sitting on my phone's interal SD card.)
3. I tried to do that Non-ADB method listed in that topic I linked to. After that I started having these problems.
4. I accidently ended up clearing the Data cache through the recovery menu thing. Just an accidental moving of the buttons. It didn't seem to effect anything.
5. I booted the phone into recovery mode and tried the Odin thing. It got stuck at File Analysis, and I tried again. It still got stuck, and I let it continue trying it while I was eating dinner. After I got back it was still on that, so I took out the USB cord and phone battery and put the Sim card back in. When I try to boot it up it goes to that PC error phone thing. (I can't exactly get an image of it, I hope you know what I'm talking about.)
And that's all I've done to it. I'd try a different USB port, but I don't have any more. I'd try my other computer, but that's a Linux machine, and Odin is a Windows/DOS executable file. I'm pretty sure the drivers are installed correctly, as I had been doing stuff with the phone via USB just yesterday.
I hope that's enough detail to help figure out something.
I'd hate to doulbe post, but I really really do need the help with this. If any of you have any advice for it all, please, feel free to contribute. If there is no fix for this, and my phone is actually bricked, just let me know so I can go get a replacement.
Did you make sure you had odin started up BEFORE you put your phone in download mode? Odin is very touchy and you have to do things exactly right or it won't work.
Yes, I've made sure to follow all of the steps right to the last peroid. I'm probably just going to have to go get a replacement anyway.

[Q]Can't flash a tot even in emergency download

Hey guys, I'm having an annoying problem here.
When I try to connect my phone to a computer, it just goes straight to charging, it doesn't even recognize on either end that a USB is connected to a computer. Now, sometimes I can force it to work, but that is like around 200 tries and it finally connects. I suspect it might be in test mode (but I'm not sure, I tried pressing # on the dialer to see if it pops up but nothing shows), so I've tried to follow the instructions to flash a .tot file by pressing power + volume up, unfortunately, the computer still doesn't recognize anything is connected, and neither does LGNPST. I have all the drivers properly installed (I was able to successfully downgrade to zv7/install gingervolt last week), and am out of ideas on how to get it to work. Any help would be appreciated.
So far I've tried about 6 different cables in four different USB ports to no success.
pow + vol down (hard reset) should work, phone has to be completely off. not even the charging animation. unplug from pc, pull and replace batt, put batt in then plug into usb then hard reset (hold until factory reset pops up) 10 secs or so
this has allways worked for me no matter how badly i messed up the phone.
Well, I tried your method of a hard reset and it still didn't work. Any other ideas? Is there any way to make the computer force to recognize the phone when its in emergency download mode?
I'm having a similar issue on a friend's phone
Edit: http://forum.xda-developers.com/showthread.php?t=1564941 I think this is the solution
I followed the instructions exactly, and LGNPST still isn't noticing anything and won't go into emergency mode......this is frustrating me....if I can just get this thing back to stock and lose cwm i can just take it to the store and get a new one.....
*EDIT* Well it randomly decided to connect to my computer again. The problem now is as soon as it goes into download mode(LGNPST is at around 11% complete and about to start on the Masterbin), it loses the connection to the computer and can't finish flashing the tot file....ugh..
Anyone have any ideas? I'm going crazy over here trying to figure out whats wrong. Every like 100th try, it will connect to the computer still, but if I try and run mt's revoallinone package it fails to unroot (says access is denied or folder not found), or try lgnpst it loses the usb connection the second it goes to that download screen.
Depending on what version your on or where your at as far as root stock etc this may or may not work i am at a loss, try this http://forum.xda-developers.com/showthread.php?t=1626198
Yeah I've tried that. On the occassion that the COM port reveals which port is the phone(usually on the 100th time of reconnecting the usb cord and successfully able to go into usb debug) I run that program, only for it to state that this is not a lg revo and auto close before I can get all the log data. Its frustrating...I only started to have this problem when I installed GingerVolt.....
Will adb recognize your device, because i had the same issue on a newer revo, you say your on gingervolt then you should be able to set up root acces and push cwm through adb then boot to cwm and flash sonething anything a recovery or do a wipe from there and i believe i saw a method in the forums for installing a stock os fron a zip. All depending on usb connection though
I have cwm already on there. I want it and the root off and back to stock, but I can never flash a tot and unfortunately I have no experience with adb, but I guess I'll google instructions to unroot via that and see if I can go back to stock via it as well.

[Q] Cannot Enter Recovery Mode

Hello All,
Hoping someone will be able to assist me, though I'm starting to lose hope.
I have spent all day so far reading threads, and trying various suggestions and fixes, but nothing has really helped and I'm beginning to think the phone may just be kaput.
Initial issue was nothing out of the ordinary; woke up to find the phone was not responding so pulled the battery. After putting the battery back in, the phone would no longer turn on. Uh oh. Did the obvious, repull the battery, try again. Nothing. Connect to charger (nothing happens, no charging icon on screen). At this point I think the battery has died so I bought a new one. No change, phone still won't turn on and nothing happens when I plug it in to charge.
So now I connect it to my PC, and I get the installing hardware message trying to install the APX stuff which fails. After some research, I manage to get the APX drivers installed such that the phone is detected when I plug it in. More research, decide to try the AOI Toolkit to backup everything first. This works ok.
So now I try and enter recovery mode via Power key + Volume Down key. Nothing. Ok, change the recovery image then. Device is not detected via ADB method. NVFlash method instead then. The bootloader loads fine, the screen wakes up and shows the S/W Download... message. I figure this is a hopeful sign. I try all 3 (ics-cwm-5, ics-cwm-6, twrp-2.5). They all flash successfully. However, I can't enter recovery mode with any of them. Once I disconnect the phone, insert the battery and then hold down the Power + Volume Down buttons, nothing ever happens.
I've also tried the LG Update Tool and the Smartflash options, but the phone is never detected.
As a last resort I repartitioned. This also worked ok, but still no recovery mode.
tl;dr
Phone won't turn on, show as charging, or enter recovery mode. Works when connected as APX with AOI Toolkit.
Am I missing something? Doing something wrong? Any assistance is greatly appreciated. Thx.
Bump
Okay, I'm bumping this thread myself (mostly because I'm an idiot and this could happen to me, too), but to give you my two cents: Have you tried the Full Brick Repair tool? You flash it through NVFlash and apparently "it cures any brick". Try it and tell us how it went.

Thanks for the suggestion. The flash process itself completed without issue, but still nothing once the battery is inserted and the power button is pressed. I'm going to assume there is some sort of hardware issue at this point and consider the phone officially dead. Now, where's my hammer...?

Don't give up yet. Try smartflash and flash stock, or whatever. Seriously. Just keep on trying. I had a Samsung Captivate a year back and something similar happened where I woke up one beautiful morning, tried to unlock my phone: no response. I thought I had an SOD, so I pulled the battery out, reinserted: bootloop. Entered recovery, can't flash anything, unable to mount system/data partitions. Turns out my internal memory/ROM got fried. Yay. But until then, I tried every possible option. Wow, this turned out to be a bit depressing. Just try more stuff. After you've tried everything, and I mean everything, declare the phone dead.
I think i have a similar problem. Just woke up to find my phone to be dead. Tried the usual methods, nothing. Best it could do was from time to time show me a battery sign with a red triangle and a whtie exclamation mark in it. Then sometimes i manage to get into the recovery mode, there i tried practically everything. Used restore, it shows that restore was a success, but when i reboot my phone i get into an endless circle of bootloader icon appearing and dissappearing,
EDIT: somehow from the countless attempt it fired up.
Make sure to have the right bootloader before nvflashing unbrick roms....

Try to flash a new recovery image in apx mode.
And edit the /dev/block/mmcblk0p3 partition your self.
seek=6144 count=75 bs=1 / boot-recovery
Thanks for the added input and encouragement folks.
Just reporting an update:
Having been unsuccessful more times than I could count, I decided to physically disassemble the phone (normally Engineering fix #2, but performed out of order on this occasion). I have zero idea why it should have made a difference, as all I did was take it apart and then put it back together, but the phone has groaned back to life.
Of course, then sausage-fingers here managed to tear the digitizer cable when doing the final reassambly... /facepalm
Anyhow, I have a replacement on order, so I'm hopeful that when I receive that in a few days I'm back to a fully functional Optimus 2x!!

[Q] No IMEI. Need some help.

I installed a new charging flex cable and when I went to turn the phone back on, I have no IMEI. I remember backing it up but I am having zero luck finding it. I am hoping I did not delete it. Am I screwed if I cant find that backup?
So i was going to flash back to stock to try QPST, but when I go into download mode it does go into it but 3 seconds later the screen shuts off and my computer tries to install like 20 drives and wants me to format them. I am getting frustrated as heck. I tried flashing a new ROM (xenonHD) but it does that same thing.
