Easy Root Official V30B Stock

OK, based on the previous topic on rooting V30A, here is the updated package for those people who want to just root V30B, while keeping the stock bootloader and recovery. It's an image of /system directory (taken from the new V30B) which includes su and superuser.apk.

(filesize: 286,931,373 bytes, MD5: c787ef960b18e222b23327eaa34db0f5)
Just connect your phone in NVflash mode, and run the batch file. Successfully tested by me. Enjoy! I take no credit for the method; I am just providing an updated system.img.
As noted above, this rooting method does NOT install unlocked bootloader or CWM! If you want unlocked BL and CWM, the P990 AIO Tool is the easiest way to do it (it also does many other things -- if you haven't tried it, give it a go, it's wonderful!).

Nope, sorry. This is only root without messing with the bootloader and recovery, nothing more.

I am on stock 30a. Can I flash this.

This is for rooting V30B, so you need to flash this ROM first.

Flashed SmartFlash' able ICS V30B (FLS+BIN) from this post thanks to trocopassu
and then NVFlashed this V30B root....
ROOTING WORKED FLAWLSSLY, NO DATA LOST. Amazing Rooting Tool. Works 100%.
Thanks a lot @kt-Froggy True surprises and happy moments on this Merry Christmas.
My FULLY POSITIVE review on UNROOTED V30B is here and also here
5 stars to both rom and root. :good:
EDIT: Seems CWM not included. Try Install ROM Manager from GooglePlay and CWM from it.
EDIT2: Seems RomManager is not recognizing device so cannot CWM.

Hi,
There are several 30B available which are for Singapore, Thailand , Vietnam ..., which one is base ROM you rooted on?

The same goes for V30a on Homero's Opti-ICS, I had to download Rom Manager but it not recognizing devie so can't CWM either. Any ideas why?
Rom Manager V 5.5.1.3 but when I reboot into recovery says CWM-Based Recovery v6.0.1.5

Recovery v6.0.2.5 from "pengus77" or Recovery v5.0.2.8e from "spyrosk" are OK!...

As far as I understand, you have to have an unlocked bootloader first to be able to install CWM. If you flashed V30B BIN/FLS and rooted using this system image, you are still on stock (locked) BL...

Seems like it automatically starts install some rom images.
Try to delete all the rom image or backups (backup your SD first) that you have in your sd.
But first of all try to use QuickBoot app instead the RomManager app.
It's free and you find it in Play store.
Bye

..first check if you have the stock recovery yet like Xonar says..
..second, try to download again the recovery from RomManager's menu (don't know if ics OB is supported) and retry..
If nothing happens..maybe it's better if you flash the stock V20x with the CWM already injected and then install the flashable V30B that you can easily find in the developement section.

You’re welcome
You don’t have to search for stock recovery(probably you never find it )..I think Xonar want to know if you had already installed the Clockworkmod or not..because some time ago there where some problems to inject the CWM in the stock V30B rom.
(if you installed the V30B rom with smartflashtool you surely do not have the recovery and you must pass throught the V20x)
I wish had posted the link of the resources you need but I can’t ‘cause I am a new user too
If wrong something I hope that Xonar can correct me..
Good luck :fingers-crossed:

Yea and stock recovery does factory reset when entering it and then just continues booting.

The only stock rom that I could download is the v10a. can I install CM10 from there?

Right, but you must be sure that it has the CWM injected..or you are again at the start point
So when you are in recovery after had flashed v10 with smartflashtool..flash the .zip of V30B...

You can download official CWM recovery. Search here: http://www.clockworkmod.com/rommanager for LG Optimus 4X HD.
Then you can install with terminal, fastboot or sth else - I don't remeber well.
Then the fun starts. (On XDA look for ROMs and kernels)
And read the instructions carefully.

Unlock ur bootloader 1st!

Agreed but after reading posts on how to install, it requires an unlocked bootloader. is it necessary or can it be done without unlocking bootloader ?

It can be done without unlocked bootloader, but then you will be unable to install custom ROMs. So if you're on stock JB, unlock bootloader if you want (warrany will be woid).

That's not hard first you must root tour phone then install rom manager choose tour phone from it flash recovery reboot in it then flash zip file that's all

First you need to unlock your bootloader after that you can Install CWM or TWRP.
After doing all this you can Instal CM or any other ROM.
If you try to install the CWM or TWRP without unlocking the bootloader you will get the boot signature error and you won't be able to boot into recovery (please correct me if I am wrong.)
Don't Forget to make nondorid backup before you try installing any ROM in case you know what I mean
and next time post it in Q & A thread please..
Have fun mate.

yes you will get an boot image signature if you install cwm or twrp with locked bootloader
the only way to flash a custom rom on an locked bootloader is to adjust the rom to the stock kernel and device and the flash it via a bootstrap( like dexter did it)
but nobody is going to do it if you have tje possibility to unlock your BL seems that you have to stay at stock rom if you don't have the know how how to do it

It's not a trick, but it is pointless for a high end device as all it will do is increase lag and kill the SD Card due to the high amount of writes.

You really haven't given much informaton to go on. Basics with any help request;-
What are you trying to achieve?
What version are you running?
What ROM were you on before?
Rooted?
Bootloader locked or unlocked?
What recovery have you installed?
EXACT error message - this is the single most important detail!!
There are plenty of guides around if you are trying to get from 'Stock' to CM10.1;-
Upgrade to 'Stock' JB first
Root
Unlock bootloader
Install CWM (v6.0.3.1)
Install CM from zip
Install gApps from zip
.....
Profit

Because I might forgot bootloader and my device is already wiped out clean(so i cant even return to stock because the whole device is empty).

Highlighted in red for a very good reason. You'll need to reflash your stock v10e first, yet again there are guides on how to do this. Once you have the phone back up and running on v10e then read carefully and make sure you understand all the steps before trying again

Yes, you can use aboot for D410 on D410H/D410Hn. So, in your case, go to the first link and download the L90_D410_v10d_aboot.zip, then just flash through Terminal Emulator (guide also in the first link) and you're ready to flash Custom Recovery and Custom ROMs.

If you just want original android ported to your device, go for CyanogenMod 13 (soon, it'll update to CM (CyanogenMod) 14, which has android 7.0, Android Nougat; https://download.cyanogenmod.org/?device=w7). If you want CM13, but with some other things, go for Temasek's one (http://forum.xda-developers.com/lg-l90/development/rom-temaseks-unofficial-cm13-0-t3339783).
