[How-To] Manual Rooting of LS670ZVH/ZVJ (+ links to root ZVD/ZV9)

Re: [How-To] Rooting LS670ZVH

Boot to recovery.. Power down, Push and hold Home+Vol Down+Power and it will bring you to recovery. It will say Xionia on the top of that menu. Good luck

I'm all good and using gROM 1.1 and a nice new theme. Thanks guys

Re: [How-To] Rooting LS670ZVH

Hey Guys I have seen alot of posts about this issue I am having but no solid answers on a fixes or steps to fix it.

Trying to root my LS670 and upgrade it to ZVH. I was able to get it to ZV9 and root it then run the update to ZVH. When I tried to apply the root (ZVHroot.zip) I hit a brick wall.

Currently my phone boots to the stock recovery screen with the standard 4 options and and the triangle background. The Yellow text at the bottom says:

Android System recovery...
Do not pull out the battery!!
Finding update package...
E:Can't find command file CASHE:
recovery/command
Installation aborted. no valid imange in CASHE.

When I try to choose any option the text on the recovery screen goes away and nothing happens. When I say nothing happens literally the background triangle image is still there but the phone takes not actions even after sitting for over an hour like that. I have tried removing the battery and rebooting at least 20 times.

ADB -reboot works
But adb shell does not it gives :
- exec '/system/bin/sh' failed: No such file or directory (2) -
check_LGE_official: fopen(/sdcard/ally_security) error
adb push/pull commands do not work

Anyone have ideas or help they can provide? I have seen people say they had this problem and the respond with "nm I fixed it" with no information on how.

You need a custom recovery. Try xionia.

If I can figure out how to get it into the phone. It won't let me push or pull with adb. adb-remount gives me a "remount failed: Operation not permitted" I am guessing the USB is not in debug mode or something. Not sure where to go from here.

Re: [How-To] Rooting LS670ZVH

Turn on usb debugging and adb push/pull will work. Also, confirm you are still rooted. You shouldn't need the remount command...

Is there a way to turn on USB debugging from adb or the recovery screen. The phone will not boot to android so not sure if there is a command to do this.

When you say you were able to "get it to ZV9 and root it" what did you do? Revert to V9 or just install V9 recovery? zvhroot.zip just copies some files to your phone and asks to to type a few commands in adb shell. Which step did you encounter problems?

Currently my phone boots to the stock recovery screen with the standard 4 options and and the triangle background. The Yellow text at the bottom says:

Android System recovery...

This is harmless and you can ignore it. The Recovery thinks it needs to install an update from Sprint (stored in the cache partition) but there is nothing there.

When I try to choose any option the text on the recovery screen goes away and nothing happens. When I say nothing happens literally the background triangle image is still there but the phone takes not actions even after sitting for over an hour like that. I have tried removing the battery and rebooting at least 20 times.

So when you choose wipe data/factory reset it does nothing? or just when you choose "reboot system now"?

ADB -reboot works
But adb shell does not it gives :
- exec '/system/bin/sh' failed: No such file or directory (2) -

This is an expected error. You need to "apply sdcard:update.zip" or you will not be able to adb shell.

check_LGE_official: fopen(/sdcard/ally_security) error

I don't think I've ever seen this error before, but I usually don't skip applying update.zip unless I'm testing things out to write instructions.

adb push/pull commands do not work

This is expected, same problem as above with adb shell.

Anyone have ideas or help they can provide? I have seen people say they had this problem and the respond with "nm I fixed it" with no information on how.

Usually it is because they missed a step in the instructions and either they figured it out themselves or someone pointed it out to them.

I think the other problems you mentioned are already addressed. Your real problem is your phone won't boot into Android. I would try a "wipe data/factory reset" first, the "reboot system now". If that doesn't help, you can try *deleting* the update.zip on your sdcard and replacing it with the *ZVH* update.zip from Step #1, then do "apply sdcard:update.zip" from Recovery to reapply the ZVH update. If that doesn't work, you may need to reflash a working Android using KP500.

Don't worry, as long as you can boot into recovery, you should be able to recover from this. Just don't go off and do too many random experiments or it can get worse.

Re: [How-To] Rooting LS670ZVH

I reverted the phone to V9. It was working at that point. THe visual differences from vzh and v9 let me know that v9 was installed I used z4root to root the phone verified superuser was installed and even used root checker to make sure it was rooted.



Currently on the stock recovery screen there are 4 options. All 4 options so the same behavior. No mater what option I press. the recovery screen text goes away and it sits at the backgroud. This happens with ALL 4 OPTIONS!

At this point I am hoping to to unbrick the phone. Is there a certian update.zip I should try to apply.

Oh I did forget to mention kpe500 seems to work fine also. the updates go thru exactly as the should. so is there a different .cab I should try?

So you were able to boot into Android at this point. Do you remember if you installed stock V9 recovery or did nothing with recovery? Reverting with KP500 usually won't touch your Recovery partition, so if you had the VD recovery partition before, you probably still have it.

So at what step did you go from Android that boots to Android that doesn't. Were you ever able to boot into ZVH Android after Step #4? Were you able to perform the factory reset in Step #5? There is nothing in zvhroot.zip (Step #6) that could have caused what you are seeing.

Currently on the stock recovery screen there are 4 options. All 4 options so the same behavior. No mater what option I press. the recovery screen text goes away and it sits at the backgroud. This happens with ALL 4 OPTIONS!

Ok, well that explains why you didn't "apply sdcard:update.zip" and hence your other reported problems.

At this point I am hoping to to unbrick the phone. Is there a certian update.zip I should try to apply.

As I mentioned, your phone isn't bricked if you can boot into Recovery. If you try random things you could brick it. Even if you follow directions people give you, you can brick it, just less likely.

Oh I did forget to mention kpe500 seems to work fine also. the updates go thru exactly as the should. so is there a different .cab I should try?

Nope, those cabs are straight from LG with full Android flashes (except for Recovery)

Re: [How-To] Rooting LS670ZVH

I successfully updated, but had some issues with the official gingerbread update (as others have reported here), so I am now trying gROM to see if that fixes my problems. If it doesn't I would like to go back to stock VD. I made a backup of my VD before I upgraded to VH. Can I simply flash the backup if I want to go back? I wasn't sure if having the VH radio would cause any problems or does the radio get downgraded by the backup?

It likely would cause you issues with data connectivity. You will likely need to revert back to ZVD to get the ZVD radio, then you can restore your backup.

Ok, thanks. Now how do I revert back to ZVD? I found this thread, but wasn't sure if I had to follow all those same steps since I am not trying to goto V9, just VD. I was hoping it would just be a matter of flashing a zip off the sd card but I am guessing not...

EDIT: Would I just use the K500 tool to force flash VD?

 

[rocko_opt_s]

Re: [How-To] Rooting LS670ZVH

If you accepted the OTA ZVH update prior to reading this thread, then you will need to revert to VD first using this thread. Substitute the VD cab file in the reference section for the V9 cab file in the main instructions. Then follow the ZVD root instructions referenced above.



If I used lg mobile sup. tool to revert to v9, can I use it again to go to vd. I needn to be on vd, but I missed the step of replacing the v9 with vd. oops,... am i buying a new droid?

Yes, follow the instructions in my signature, substitute the VD section in the reference section.

If you Android takes a long time to boot (over 10 minutes) do this
Factory reset from stock recovery

It would be as simple as flashing a zip but we don't have the ability to flash the radio except going through LG software.

Gotcha. Thank you very much for all the help. I am new at all this so still learning. One quick question, will force flashing VD using the tool replace my xionia recovery?

In most cases no, but it is possible under some situations. You can root VD and place back whichever recovery you want, so it isn't that big an issue, as long as you are aware of it.

Re: [How-To] Rooting LS670ZVH

everytime ive force flashed VD, it gave me VD recovery

Re: [How-To] Rooting LS670ZVH

Is there a way to do all this using a Mac OS X 10.6.8? Any input would be great.

You can use KP500 to flash versions V8 to VD. You can do so repeatedly.
