Root Guide to Rooting Without a Computer

[350X]

Here is a guide to rooting and installing a custom recovery on your Optimus V without using a computer. All steps are performed using the phone only.

READ THIS ENTIRE GUIDE FIRST AND MAKE SURE YOU UNDERSTAND ALL THE STEPS BEFORE STARTING.
Before we get started, be aware that rooting does void the manufacturer

Ahh here is the missing info that should come before step 3 somewhere.

"Install custom recovery image

The recovery image is an alternative bootup instead of normal Android Operating System. It allows low-level operations such as backup/restore a ROM, wipe partitions, and flash ROMs.

4. Download and copy the recovery image VM670NH_recovery.img (works with new & old OV screens) onto your /sdcard."

^ with out that bit of info, this guide will make you pull your hair out, mods plz put it in somewhere to help other.

Looked easy enough to figure out. He gives you links to two different recoveries and explains which one to use for the type of ROM you want at the bottom of the post. Both are clearly labeled, IHOrecovery.img and xioniarecovery.img.

 

[350X]

he says those are for flashing roms, so you must pick a rom ahead of time to know which one, and I wasn't going to use a rom.

"I recommend using the xionia recovery to flash the 2.2 roms and the IHO recovery for the various IHO ROMS(Backside, MiRaGe, Bobzhome). "

I used this method to root last year and now I want to unroot.

I've found the various unroot methods that have you flash a stock recovery and the like, but I'm not sure I need them. I never installed another ROM. All I did is remove some bloat and use Link2DS. I'm still sitting at VM670ZV4.

So does that mean I can just launch Gingerbreak and click unroot? I think I have to original recovery (vrecovery.img) on my SD card if it comes to that, but I'd rather just click "unroot" in Gingerbreak and be done with it.

Thanks in advance!

If you want to unroot, I would suggest you put the stock recovery back first. There is no way to do it after, and a factory reset with a custom recovery will brick your phone. Once you reinstall the stock recovery, boot into it to make sure you have right one (should only have four options). Then you can unroot using gingerbreak.

Thanks for the response.

I think I follow you. But I'm still confused. Do I really need to do that if I never installed another ROM and am still sitting on the stock ROM?

I find it kind of amusing that I was too chicken to install a ROM so I sat at stock for a year and now have to install one (well, go through the motions anyway) just to unroot. So if it seems like I'm resisting it's because if I'm wrong on this it means I should have been rockin' custom ROMs all year!

 

[riggerman1]

Are you still on the stock recovery? It should only four options, and have a blue screen. I believe the options are: reboot system; apply update.zip; wipe cache; wipe data, factory reset. That may not be the correct order, but if you have more options than that, then you have custom recovery and need to change it before unrooting. To boot into your recovery, power off the phone, the press the home, volume down and power button until the LG logo pops up, then release.

Just a thought. Read this:http://androidforums.com/optimus-v-all-things-root/563443-how-flash-zv9-update-step-step.html

If you install the ZV9 update it will remove root, replace any ROM with the stock ROM and replace any custom recovery with the stock recovery.

Easiest way to revert to stock that there is. Just follow the guide up to how to install the update.

Thanks Riggerman....duh, it's amazing what you forget in a year (especially at my advanced age)! I indeed am NOT sitting at stock. I'm running Xionia CWMA 1.2518.4. So I guess technically I did flash a recovery. So my understanding is that I need to get rid of that to go back to unrooted stage. So that means I can restore my vrecovery.img, I believe. Of course, since it's been a year, I don't actually remember if that *is* my recovery or something else.

Which then leads me to AndieOpie150. Thank you for the ZV9 update link. It looks like that indeed is my best option. When I read the guide this @ 2am this morning I thought I was stuck at step 1 ("If you have CWMT or MultiBoot you will need to change it, or this WILL brick your phone"), but upon getting some sleep, I realized that "Xionia CWMA 1.2518.4" does not = CWMT or MultiBoot ;-)

So.... unless I'm totally missing something (and if I am, let me know so I can just throw the d*%# phone out the window now , I'm going to dive in the ZV9 method (and stop at step 12). Phew!

Thanks again everyone for the assistance.

Yes the ZV9 should be safe to flash with the xionia recovery. Just download it, use a file manager to move it to the root of your sd card, boot into your recovery, and select "install update.zip". If you want the radio to update to the new ZV9 baseband, you'll have to flash the update one more time from the stock recovery, the reboot. You should then see s message on your screen about flashing the new radio.

Great stuff. Thanks.

So I can skip the Gordita.bat stuff from the "How to Flash ZV9" page if I just want to remain on the stock ROM w/ stock radio? That's it? Seems too easy

And then after all this I can use the Privacy/factory reset and not worry about it being bricked?

 

[AndyOpie150]

Correct. All the factory reset does is wipe all user data. Just like selecting the wipe data/factory reset does in a custom recovery.

I'm having a little issue. I wanted to try CM9.0 RC2-VM670-BobZhome ROM with the VM670NH_recovery.img recovery. I placed them both on my sdcard's root directory.

I renamed VM670NH_recovery.img to Irecovery to be easier to type into terminal.

When in the terminal I typed:

su(return)
mount -o remount,rw -t yaffs2 /system /system(return)
cat /sdcard/flash_image > /system/bin/flash_image(return)
chmod 755 /system/bin/flash_image(return)
flash_image Irecovery /sdcard/Irecovery.img(return)

and recieved this error:
can't find Irecovery partition

Any ideas?

 

[AndyOpie150]

Error in your code.

line #3 and #4= Those commands are for installing the custom flash_image from the sd card to the /system/bin and then changing the permissions on it to rwxr-xr-x. They are not needed if you have already installed one.


Line #5 you need to type in this: flash_image recovery /sdcard/Irecovery.img.
What those commands are doing is having the flash_image install the Irecovery.image to the flash partition.

Look in your code. Where it says flash_image Irecovery it should say flash_image recovery (this is the recovery partition I mentioned)

I really should not have tried that first thing in the morning, such a silly mistake I made... All is good and working now

Hopefully I didn't just eff things up for me royally. This is my second root I've done unsupervised. Anyways, done everything to the letter. But when I got to the point where I was in the recovery menu, it only had the first 4 options, not the last four (which include the backup option) so I COULD NOT DO A BACKUP. So I proceeded to reboot.

So far, everything is fine.

Also - wanted to point out that in Terminal Emulator, I had to type "flash_image.bin" instead of what directions say which are "flash_image". When I typed flash_image, it said no such file or directory.

If you only have four options, you don't have a custom recovery.

Don't woory about the title of the thread it's just where my little install tutorial post took shape.

So if I wanted to have more memory to add an app I would have to do this? It all looks confusing, and I ain't the most tech savvy person. Will I lose all the stuff on my SD card if do this?

 

[AndyOpie150]

Rooting won't add internal memory space. It will allow you to make changes to the phone that will allow you to gain more. Usually to accomplish this you have to install a custom ROM that is developed for this purpose. The Harmonia ROM (Froyo version) is the best for this purpose.

 

[MyMommaDog]

you do all this on the phone right cuz i tryed and agin xionia link not supported on this device is what i keep getting

 

[MyMommaDog]

none of the links worked not supported on this phone

 

[brotherswing]

It's an OV, right? Xionia was developed specifically for it....
