HOWTO : No computer needed! Root, Install Custom Recovery and ROM

[Scott Hunter]

Hi guys,

First I want to say that none of this work is mine all credit goes to the original creators. Also this is my first thread so be gentle

So this is how I rooted, fixed my 3g, installed the Cannibal Open Touch recovery, and the Cold as Ice Rom . This was done from a stock zvj fully updated phone without using a computer.

***Some general warnings***

You are responsible for your phone. These instructions worked for both phones I tried it on. That's the extent of my testing As always there is a chance something can go wrong so if you brick your phone not my fault. Please read about what you are installing as there is alot of information in the forum post's that i've linked to. This will wipe all your user data.

1.Download Androzip File Manager from google play ( Google Play link) this is to be able to download .zip files and to move the file to the correct location.
2.Download the official zvd downgrade from sprint here : update.zip (taken from this post http://forums.androidcentral.com/lg...sprint-zvd-froyo-downgrade-now-available.html)
3. Open Androzip and move update.zip from /Downloads to the root of the sdcard.
4. Turn off phone.

6. Choose wipe data/factory reset
7. Choose wipe cache
8. Choose apply sdcard : update.zip

10. setup phone normally
*optional* I was having some 3g and data problems( Error 67 and data connectivity) so I updated my profile and prl ( menu key, settings, about phone) Do NOT do a firmware or system update. This fixed my issues with data.
11. Download Androzip File Manager from google play ( Google Play link) this is to be able to download .zip files and to move the file to the correct location.

would it work on karbonn a2. pls rply

 

[elvisruns]

so whats the workaround when we go to download gingerbreak (from XDA's website) and the only thing that shows up on my phone is SBS Gatekeeper's Virus Blocker Lite showing that the file download was blocked because it contains a virus?

 

[DoomMunky]

Yeah, the way the thing works is by exploiting the same thing that rootkits do; don't worry about it. I've been using it for ages and it's fine. I finally just added the file as an exception in my virus manager (MSE).

Seriously, it's not a rootkit.

Don't know what the workaround is, though, sorry.

 

[AndyOpie150]

It doesn't contain a virus, it's just the way the exploit is structured that it is seen as containing a virus. Turn off virus protection or delete it prior to download.
I used Dolphin Browser to download to phone.

You need to have the USB debugging box checked in: menu/settings/applications/development.

Move it from the download folder to the root of the sd card, then install. When finished select done.
Go to app drawer and select the app.

The exploit is totally safe and will not harm your phone.

It could take anywhere from one to ten tries to get it to establish root access.
If after 12 minutes it doesn't auto reboot your phone then pull battery and try again.

If you root your phone, and don't have a custom flash_image and recovery, then when you mess something up you will have no backup to fall back on. The Stock recovery doesn't have the capability to back up a ROM. A custom recovery does.
No backup, a messed up ROM or a brick.
Never root without installing a custom recovery, and making a backup of the ROM first (don't even think about deleting the bloatware until a backup is made)
I know, I didn't know about the custom recovery and the backup with my first V (the stone cold brick)
