[Q] LG-VS700 issues (dubbing, hard reset etc) - Android Q&A, Help & Troubleshooting

I swapped my son my Droid 4 for his LG-VS700 and I attempted to root it yesterday but failed
It seems there's a lot of issues I'm having and not sure how to resolve them
For example the HARD RESET for the LG-VS700 is
-Press and hold the Power button+Home key+Volume down key simultaneously then release 3 seconds after the LG logo appears.
-Once the LG logo disappears, an Android logo will briefly appear indicating that the reset is in process.
-The reset process may take up to 90 seconds to complete.
When I do this it shows the Android Logo and starts to reset then it reboots automatically and never resets
that's one issue
another one is the USB Debugging
On the Droid I could turn that off and on. It did not matter if it were plugged into the laptop or not. Is it normal that the USB Debugging option be "Greyed out" when the device is plugged into the Laptop?
I've tried every which way to get the laptop to recognize the device but it never shows on on my adb list in cmd prompt and every guide I've tried to use doesn't work because it seems nothing is detecting the device
I've updated with the latest drivers and installed the android sdk tools like many guides have suggested. I think once I've actually gotten the little debug icon to show up on my device screen in the upper corner but now it only shows the USB icon and charges.
I've tried several USB plugs incase it was the plug .. I've ensured all software was up to date. I've actually installed and uninstalled software over and over thinking it just didn't install properly
These are very odd errors to me that I've not seen before and cannot find answers to
1. Hard Reset not working properly (reboots instantly on the Android Logo)
2. USB Debugging being "Greyed out"
3. Device just not being detected by Laptop even with updated software

[Q] Can't get to Download Mode - stuck on loading screen

Hi All,
So, I tried to flash Cyanogen mod last night using the instructions here: http://wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide. I was coming from a BIONIX ROM that flashed fine.
Anyways, the phone went into a reboot loop in the recovery screen and I foolishly just held the power button until it stopped. When I turned it back on it was broken. That is, now all it does is display the white Vibrant logo in the middle of the screen with the smaller Samsung logo below it. If I hold the power button for about 8 seconds the screen goes black for about 2 seconds and then comes right back up to where it was. I can't seem to even turn the phone off any more. It just stays on that screen permanently unless I hold the power button, in which case the screen is off for 2 out of every 10 seconds. Yanking the battery of course turns it off, but putting it back in immediately returns it to the state I've described.
I've scoured these forums and tried every button press + battery state + cable state + SD card/SIM state combo suggested, but the phone won't go to download or recovery mode. I found one thread describing the exact same problem. The OP said he'd try a jig and then disappeared without any further updates. I'm going to try to get my friend to make a jig using one of these sets of instructions

http://factoidz.com/how-to-unbrick-your-samsung-vibrant-galaxy-s/
but until then my questions is: does anyone have any experience with this problem (can't even turn the phone off)? If so, do you have any recommendations? Did a Jig work?
keep trying to get to download mode, pull battery, plug usb in to computer and to the phone, while holding both volume up and volume down pop in the battery. People have tried hundreds of times with it not working and then all of a sudden *bam* download mode.
So... my friend made me a jig and it works in that I can see the shoveling droid indicating download mode. However Heimdall/Odin won't recognize my phone. Heimdall's zadig utility won't locate the phone either, even with the cable plugged in. I'm, once again, stumped.
Just an update; I've tried Odin on three different computers, two Windows 7 (64 bit) and a Mac (with Heimdall). None of them seem to recognize the phone. Device manager on the Windows 7 machine does not update when I plug the phone in (in Download mode via the jig or not) and I can't find anything about Samsung in it anywhere. However I have installed the Samsung drivers; a few different sets I've found around the forums. I've also tried a couple utilities like the Vibrant toolbox and one click unbrick. Nothing seems to have any effect. I was so hopeful when the jig worked and got me to download mode, but now it's seeming I'm actually bricked. Has anyone seen a phone that could get to download mode but still be bricked? Oh, and I checked the cable using a friend's phone; her Mac recognized her phone using the cable. Haven't tried her phone on my Window's machines though.
Once again, any help is more than appreciated.
Have you tried to see if adb is working? If it does then try adb reboot recovery? If it works there is a file I can post for you later (is in my pc) that can restore your sbl.bin and fix your download mode problems.
Thanks for your help everyone, the problem was apparently resolved by a new cable; which is strange because the old one works for data transfers... just not for flashing apaprently. :S

[Q] Phone won't turn on??

I'm currently using a P769 model with JB, and it's never been rooted. I remember the phone was 100% charged when I looked at it three days ago and I didn't use it at all the day after that, but when I tried to use it yesterday it didn't turn on and it hasn't been responding since (I did try to charge it a few times). Actually the exact same thing happened a few months ago but it fixed itself in a few hours, but this time it's been two days and I hope it doesn't mean my phone is completely bricked The main thing is that I want to avoid doing a factory reset if at all possible since I made the mistake of not creating a backup.
I've tried some recovery tools (LG Mobile Support along with third-party) but the problem is that nothing seems to recognize my phone as connected. Weirdly enough, when I plug it in it without the battery, it connects and disconnects continuously (the device manager refreshes itself every 3-4 seconds); I've updated the USB drivers and everything, but nothing seems to work. Not sure what the Recovery Mode key combination is but I'm assuming the phone has to boot first for Recovery Mode to even be accessible anyway, so that's probably out of the question. However I have tried Vol+, power and Vol+, power, home, and nothing happens.
To make the recovery software recognize your phone,you must put it in S/W mode by disconnecting your phone,taking out the battery,reinserting the battery and then,while holding the volume+ button,plugging it into your computer(keep holding volume+ until the screen says S/W just to be safe).At least that's what I always did.
Hmm... I tried that, and nothing happens on my phone, but I get a popup from the system tray on my computer that says "USB device not recognized: The last USB device you connected to this computer malfunctioned, and Windows does not recognize it" which appears and disappears repeatedly. It appears that no software can recognize the phone as connected at this point. I think it might be a random battery failure but I don't know how to tell D:
The thing is all I really need out of the phone is the contact and app data if possible, which is why I'm so hesitant to do a hard reset :| I read around and I'm assuming what I should do is to flash the bootloader but I'm not sure how to go about doing that since I'm getting zero response from the phone itself.....
UPDATE: Tried a hard reset anyway, but still nothing from the phone. I attempted fastboot, however, I don't know how to make it work since "OMAP4430" does appear under TI Devices in Device Manager plus an "Unknown USB [device failed enumeration something something]" under USB Controllers, but that's it.... nothing appears under Other Devices, which seems to be where the bricked phone should show up. adb doesn't seem to recognize it either.
i have the same problem with my lg p760.
any solutions?
you had a solution for this problem ?

[Q] Phone is not being seen by computer when plugged in, usual solutions do not work

Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?

Hard Brick

My device used to be able to connect through ADB and my USB cable. I even used the recent 1-Click to Unlock and load Lineage OS. I have used fast boot before.
I recently tried to use 1 Click again to load GAPPS but during the process I got a notice that my device was disconnected which it really wasn't and the processed stopped. So now my Fire HDX 7" does not turn on at all. I know the battery was good and I left it plugged in overnight.
I have held the power button for 4 minutes. I have tried holding power+volume down, power+volume up. Nothing I have tried is working to even start it up. When I plug into the computer nothing is recognized. It used to be recognized but no longer does.
Can someone confirm I have a hard brick or is there hope for recovery?

H6 allwinner tv box stuck on android.

Hi people!
I have this headache with this tvbox since it got stuck at android logo (idk what my uncle did to this device). I can't enter recovery mode, despite I tried with all methods like hard reset button, usb flashing with phoenix suit, or microsd card flashing, it only stays at red light. It even doesn't get recognized by windows (It says "unknonwn device" on device manager).
I tried everything, installing adb legacy drivers, tried with both usb ports, holding the reset button for a looong time and nothing.
So please, I need help of this great community!
Did you find any solution for this mate?
take a wooden toothpick, press the button through the av output one second after power on, after 5 seconds release the button and wait for the device to be cleaned. after that the box will work
