Root Xionia Boot Loop on LG Opt VM670

I think I have tried every thing to make a long story short. Adb and fastboot and power up buttons but I have the same problem.
I was useing xionia to clean out all the caches to prepare for a new mod and the main reason for that was because all my setting were getting removed every time I rebooted because the stock recovery kept cleaning them out, (because I used the stock system cleaner awhile back and xionia fixed that) so I though that if I installed a new mod it might fix that problem. I was wrong. So now I have a system that when powered up the first thing it does is shows the LG logo then formats all data and cache then reboots show the LG logo and continues to the BACKside logo and stops. I have read about others having this problem to but the fixes that worked for them isn't for me. I have noticed some thing new and that is while the stock recovery is formating it I push the power button the yellow text disapears and I see the Xionia name in white at the bottom of the screen, so it is still there I think just getting bipassed by the stock recovery. none of the adb or fastboot commands work except the fastboot reboot bootloader then my computer can't see or find the phone.
Sorry this is so long winded and I am sure there are some things I haven't talked about here just the basics and the facts.

Is there any hope for me and my phone VM670 LG Optimus V
 
All I get is the BACKside logo as it starts to load and sence that is all I get I can't start the debuging app or any thing else. The only adb command I an run is reboot bootloader the blue screen starts and is running but at that point I loose all connection with phone at that point adb and fastboot commands can't access my phone options will work if I remember right but that is all

It tried another suggestion the other night and that was to start adb shell and then power up the phone useing the home vol down and power keys, I let it cycle through a couple of times that is let it boot and reboot 2 or 3 times. Then while the system was loading I was at the DOS command prompt with the adb shell command typed in and then pressing the F3 button and enter keys as fast as I could. That caught the phone 3 times with the ~# but then lost it after the phone finished loading as far as it could any way. What does that tell you.

Have you tried flashing a new recovery? The one on this link is very good.

I have Xionia recovery installed on the phone but can't get it to run. Instead the stock system just keeps formating the cache and data on the first boot every time I power up the phone. I know Xionia is there because if I press the home key while the stock system is doing it's thing the yellow text disapears and I can see white text at the bottom of the screen that shows "Xionia_C" and some thing else, so I think it wants to load but it can't.
 
You have a 2.2.1 (original stock OS) phone with the Novatek screen and using Xionia recovery version 1.2518.6 or .4?

Thanks Jerry but I have been to that page to and I can't do what was done there. Maybe if I could enable the debugging mode on the phone things would be easer. Or if I could stop the boot load in mid boot then maybe I coulod use the adb shell command option because I did get that ~# for a second or two.

You have to get the timing right, and be fast about it from what I have read.

Type in the commands in your shell window first and press enter (even though they will not work). Press cntrl+c if you need to in order to stop them if they hang. Then you can use the up/down arrow keys to move between previously entered commands quickly and press enter. Try it out to get a feel for it before continuing.

You need to have it in this order:
the strings command line(s) from mmarz's post
su
adb shell

That way, you can press the up arrow, then hit enter, repeating till you get into adb shell.

Then, as soon as you see that prompt, press the up arrow twice and hit enter to get the su command in.

Then, immediately hit the up arrow till you see the string command and press enter.


I hope it works for you! ;)

I have 2.2.1 yes and it has been rooted I was in the middle of installing BACKside over ICSandwitch by the unknown artist. The ICS was running fine but every time I rebooted it was getting the cache and data I had just created by the stock recovery. So I hoped that if I instaled BACKside over it the correct way that poblem would go away. It just made it worse,

I even re did the whole formating of the cache and the delvci cache and installing BACKside twice too. It was ether a waste of time or the wrong thing to do. I installed Xionia at the same time I installed backside and the google apps twice all the time hoping I was doing the right thing.

Oh and the Xionia_CWMA_12518.4_VM_Recovery was the one i installed I think the reason I say I think is because the version I used had a option on the advanced page to use the stock format to clean out every thing, I assumed it would be ok because I was useing Xionia after all.

The last time I installed Xionia it didn't have that option. Maybe it was designed for another brand of phone, I was tired that night.

Have you tried a different PC? Perhaps there is something wrong with the SDK installation or the LG drivers.

I removed and reinstalled SDK and JDK and my USB driver today and got another computer up and running and ready to test your thoughts. It might just do the trick who knows.

Jerry; Well I tried to do the above but I just can't move fast enough. It only last for about half a second and it exacutes out of site by the time I can see what is going on it is over.

I am wondering if you or some one knows how to write a batch file that runs the commands I need something like.
10 adb shell
20 if prompt = ~# then enter su if not goto 10 if it does goto 30
30 show the command prompt with the ~#
40 end
Or in another programing language.
I am sure the PC is faster than me.
:eek:
 
I am wondering if the phone can be accessed through the com port or modem. To make system wide corrections, flashing, eraseing

I also wonder if the adb reboot command can be used with another command besides bootloader. And what kind of file is bootloader is it a .img file or a .apk file. The reason I would like to know is that I would like to try to load another app in it's place.
 
What I found out is that all USB port are not created equal. I was useing the USB ports on the side of my laptop and keep losing connection to the phone. The only thing that kept me going was what one member said and that was "The Phones are flexable and don't turn in to bricks very easy".
What I did was got the USB cable that came with the phone and pluged it into one of the USB ports in the rear of the laptop an low and behold that was all I needed to do. From there on every thing I was trying to do before work just as it should have.

SO NEVER GIVE UP....:D..:eek:
