[How-To] Root, Custom Recovery, NANDroid Backup

[blandella]

gorramit! I just messed up entering things in the emulator, and can't figure out what to do:

----press enter after each line-----
su
mount -o remount, rw /system
cp /sdcard/flash_image /system/bin
cd /system/bin
chmod 777 flash_image
flash_image recovery /sdcard/VM701_recovery.img
reboot recovery

I missed the space between "flash_image /system/bin" in the third line. It loaded something, but now it won't let me go back and fix it. It also won't let me complete the next line of "cd /system/bin" - It just says it can't be found.

How do I fix this? Is there a way I can start over? I can't seem to get it Terminal Emulator to stop running, and I can't finish this process. I can't believe I missed that space in there somehow. :-[

If you're talking about this line:

cp /sdcard/flash_image /system/bin

That's just a file copy. If you left the space out, the file copy didn't do anything since it requires two parameters. Just repeat it (without the typo).

So I've followed all of the steps in the first post to the letter, but the root won't work. I get as follows when I run run.bat:
[*]
[*] Waiting for device...
* server not running *
* daemon not running. starting it now *
* daemon started successfully *


Then nothing. I've left it like that for about a half of an hour, but no change. I have the phone in debug mode and charge only. I also have the Android SDK installed and working, although it doesn't detect my phone either. Not sure what's wrong, I've been trying to figure it out for a few weeks now.

Did you download the right drivers for your phone? Use the ones in the link from the first post in this thread.

I had a newer version of drivers installed, but I removed them and installed the ones from this thread.

 

[Pseudotsuga]

Problem solved. Turns out that you can't choose "Charge only", you just have to leave it at that screen. Not sure how I never tried that, but hey, better late then never.

Re: [How-To} Root, Custom Recovery, Backup, Flash ROMs

I'm trying to root the LG Optimus V (LG670), and I followed all of the steps, but when I open the terminal emulator and type su, it doesn't ask for permission as superuser.

Any help would be greatly appreciated.

Thanks.

Just type in the commands as stated in the instructions and see what happens.

Custom Recovery and Nandroid Backup Questions

Just a few innocent questions from a new guy on the scene. I hope I didn't miss the answer somewhere in all the reading I have done here. I just got my first android phone, and I am a little confused about the difference between a "custom recovery" and a "nandroid backup". I am very nervous to even root my LG Optimus Q, so I have read every piece I can find on the subject. It would take me a long time to save for a replacement phone if I happen to mess it up. I am confident I have the correct drivers as I had no problem getting these from the LG Mobile Support Tool. I selected Tracfone as carrier, then LGL55C to get the drivers. I installed drivers and rebooted the computer. I have plans to back up my contacts, pictures, and music. I also have a list of all my current apps I plan to reinstall. I have the LG Esteem root unzipped on my computer ready to go, but then I read this thread. My question is: Do I have to flash a custom recovery in order to make a nandroid backup? I do want to hard reset the phone from the recovery menu (before and after I root) and back it up in that factory state, preferably immediately after I perform the root. That way I can reset the phone to out of the box if I want. But I am unsure of how to do this as well unless I follow this guide to the T, custom recovery and everything. All I really know for sure is to turn on non market apps and usb debugging mode in settings, put it in charge only mode once connected then run the batch file as administrator and let it go. Oh and it said to turn off swype too lol. Please note I do not plan on using custom roms anytime soon. So can I just root the phone only for the market apps requiring root? And can I still make a factory recovery image without installing the custom recovery? I hope I am right in understanding that you must root before you can make a nandroid backup. I just want to modify it as little as possible, while getting the perks of root and getting a factory recovery image in case something goes horribly wrong. Thanks in advance to anyone who may be able to offer some advice.

Okay... you need to root the phone first and foremost. Rooting and all is scary at first but as long as your phone is charged and you follow the root instructions you'll be fine.

The next thing you need to do is install a custom recovery following the instructions...EXACTLY.

I'm going to link you to a different site for pulling the Recovery.img and all, though, it was all grabbed from here.

Custom CWM Recovery For the Q

Follow those steps exactly!

Once you get a custom recovery installed you can boot into it by powering the phone off. Once the phone is off you have a volume rocker on the left side of the phone. Hold the volume rocker as if you're trying to turn the music DOWN, then press the home key, and finally hold in the Power key. You want to press all 3 of these at the same time and HOLD THEM IN. The phone will turn on and you'll see the LG Logo, continue holding until you boot into ClockWorkMod Recovery. Once into clockworkmod recovery you navigate it by pressing the volume rocker up and down buttons and using the camera button on the right side to select items. This can be kind of intimidating at first but don't worry. The Q is a lot harder to brick than you'd think.

Once in recovery...wipe your cache and click the advanced button and wipe your dalvik cache. (This will clean up the phone a bit.) At this point you can make a backup of your CURRENT STATE. Or you can Wipe Data/Factory Reset and back the phone up then from a pure Stock Rooted Rom State. I recommend the second option, but it's up to you. It's entirely your choice, you can always create a stock rooted rom backup later on if you back the phone up with the stuff you have on it now. At this point you've rooted your phone and done the single MOST IMPORTANT THING and gotten yourself a custom recovery where you basically have the ability to save the phone in the event of some sort of failure.

Now to answer your questions...

1) You have to install a custom recovery to make a NANDroid and you really should do that at the very least.
2) Rooting cellphones used to be dangerous... not anymore. Rooting is a painless and quick process...its very safe.
3) If you do root your phone I recommend turning Software Update off in settings. **I really recommend updating the phone before rooting**
4) Yes you can root the phone simply to use root apps from the market... nothing wrong with that.

Enjoy your phone. If you have any questions lemme know

Many thanks to you jcole20. I feel a lot more comfortable in proceeding with the root and custom recovery process. I am even excited to follow progress on the AreaROM and plan to install it when I feel brave enough. I'm hooked on Android now lol. I promise to read directions and follow them carefully so I don't have to bother you developers again Thanks again for pointing me in the right direction and clearing up my confusion.

I tried rooting my phone once using a different guide and I think it half-ass worked. Some but not all root-required apps worked on my phone and I was only able to edit certain things in my system files.

I decided to try to 'reroot' it using this guide and it works 100%! I'm able to wifi tether now regardless of VirginMobile's strict limitations on my phones capabilities. All the things that didn't work before, but should have now are working flawlessly.

Thank you.

I'm glad you wanna try AreaRom, but I'm releasing AreaRomQ v1.2 on..... Wednesday (tomorrow) so wait till then to give it a shot

"error opening /sdcard/VM701_recovery.img: No such file or directory"

I managed to avoid such error when I changed the file name from VM701_recovery.img to BobZhome_VM701_recovery.img

So I ended up using
flash_image recovery /sdcard/BobZhome_VM701_recovery.img
instead of
flash_image recovery /sdcard/VM701_recovery.img

I imagine other people would have the same issue as me, so maybe change the directions. Thanks for the guide, so far so good.

Same here. Realized it as soon as I looked at the file names. Only other note I had, is the reboot recovery command did not work for some reason. It just rebooted back into android. Just had to power off after that and enter recovery using the volume/power button.

 

[eddie298]

Whenver i go into the recovery menu some text at the bottom reads

E:Bad boot message
"recovery "

Is this normal?

I may root my daughters LG Optimus V Slider. I had a couple questions.

I have rooted my LG Optimus V (NOT slider) and installed Harmonia 1.8 ROM on it.

It appears many people just root their Optimus V Slider phone and don't install a custom ROM. I thought part of the reason for rooting was to remove the VM Bloatware by installing a custom ROM. Instead, after rooting, can we just use Titanium Backup to remove some of the VM installed apps? Or if not - and a custom ROM needs to be installed, what is a good one? Is Harmonia compatible with the Slider Optimus? I haven't really seen a list of ROMs for the slider phone. I don't want to loose any phone functions due to not fully developed ROMs.

 

[jcole20]

The v has cyanogenmod7 and yes u can remove bloat after rooting wiith tibackup or a file explorer.
