[SOLVED] I need root to root my lg

jbaker22 · May 22, 2016

Hello, I am trying to root my LG vs840pp. I realize this is dangerous, but installing roms is the only way of updating a $13 2012 phone. I have looked over the run.sh of this one rooting software, and it seems solid. The only problem is that my phone will not give permission to write to the /system and /local directory. I have tried chmod 777, but I get the error that the /system directory is a read only directory.

Try doing it remotely. Download Kingo Root to your PC, plug the phone into a USB port and run the programme.

I was considering kingoroot, but I expected I would have to pay. I was Right!! Kingotoot almost installed a virus, but Panda antivirus is better than that to let a virus install. Also i unchecked the box to install chromium yahoo search. Thanks anyway. My phone is now kingo rooted.
At least I did not download this rom. It seems like a sham to jump through hoops to get a rom. Also the comments are probably stolen from another site. The first guy is always 18 hours ago and you can't even like a post without the 405 error.

Where did you get Kingo Root from? I used it yesterday to root a tablet for a customer and wanted the latest version - no problems whatsoever.

If it came through CNet or similar, I could understand it.

jbaker22 · May 22, 2016

I got it off of the windows link on https://kingroot.net/
I know cnet is no always trustworthy though.

Saga Lout · May 23, 2016

So where are you now? Did you root it? There are Android utilities that can root from within if Kingo Root failed.

jbaker22 · May 23, 2016

I did root it. I am now wondering if i can install a recovery option like cwm. I used rom manager and got no where. I put the phone in fastboot and used flash recovery cwm.img (in the right directory). I used the app reboot recovery to try to reboot into recovery mode, but I only got to fastboot.

Saga Lout · May 23, 2016

Try the power button and the volume down buttons together when you switch the phone on. That gives you the option to recover or install a APK

I use a Nandroid backup to a micro SD Card. There are two ways of doing it but one is useless in a total breakdown situation. In a partial system failure, so long as you get to open the Nandroid utility, you can restore the system to the day you created the backup.

jbaker22 · May 23, 2016

I know about that trick, and that is essentially what the reboot recovery app did. There is no menu, it is a black screen with white text telling you it is in fastboot. The only thing I can do there is use fastboot. The power button is the only button that does something (turns it off). My phone is working well, but I want a recovery so I can install cyanogenmod.

You can navigate through that menu usng the volume up and down buttons to scroll then pressing power to go into your choice.

jbaker22 · May 23, 2016

The menu says press any button to exit. Believe me I have tried. I that was true. I wish there was an easy way to unlock the bootloader.

Am I right in assuming the phone works and you're back at Post #1? The difference now is you're rooted so you can get to those system files.

jbaker22 · May 23, 2016

Saga Lout :

The phone works. I am not dealing with the problem in my first post. The first post was how do I root. Now, I asking how do I get to clock work mod?

XDA Dev is the only site I trust and have ever used for important matters like modding. http://forum.xda-developers.com/wiki/ClockworkMod_Recovery

jbaker22 · May 24, 2016

I trust xda too, but there response to questions takes forever. Thanks for the link I think that dd if of will help me. I found there is no space on /dev/block. Any ideas. Thank you for helping me so much.

I wish these links were still active.

Saga Lout · May 25, 2016

Seems to me to follow the Droidgator methodology you would probably have to use Kingo to unroot and go down their preferred rooting road.

jbaker22 · May 25, 2016

I see the recovery option screen for a millisecond, but I am not fsat enough. http://www.lg-phones.org/how-to-get-the-lg-lucid-4g-to-boot-into-recovery.html

Saga Lout · May 25, 2016

Knowing what it wants you to do, can you start doing it before you even see the screen. Mash whichever key you need to and you might beat the little beggar.

jbaker22 · May 25, 2016

The instructions are similar to fastboot the screen I have been going to, but They mention i have to restart and press it after the lg screen not before.

jbaker22 · May 25, 2016

I think I need s-off

williams-iMac:~ jbaker$ /Users/jbaker/Downloads/tools/fastboot -i 0x1ebf oem device-info
...
(bootloader) --------------------------------------------
(bootloader) Empty Device Information!
(bootloader) --------------------------------------------

Saga Lout · May 26, 2016

The iMac element of that instruction throws me right out of the window.

jbaker22 · May 26, 2016

williams-imac is the name of the computer. I copied directly out of terminal. I did not install adb/fastboot, but it works just fine to reference it by navigating to it. The " -i 0x1ebf oem device-info" was something I found online that tells me about the bootloader partitions. I think it said it can't read it because the secure boot is on (s-on).

Saga Lout · May 26, 2016

Use the direct approach. Download Termional Emulator from the Store and use the command ls to list the files. Use cd {name of folder to examine next} then ls again to list the contents. That will probably be "system" Root File Manager from the store will also show you wnat you can and cannot see.

Be careful with cd. Using it without specifying where you want to go will take to to Home and that isn't where you want to be so you'll have to restart the Terminal.
