04XHD rollback to 4.0.3 or custom rom - LG Optimus 4X HD

Specs:
¤ LG O4XHD BLACK UNLOCKED
¤ ANDROID 4.1.2 (V20a) DEU
Hey, xda-community. I got my new phone since some days. Except of the heat I love it until I upgraded to 4.1.2 (big lag for only a few features). Takes lomg to draw my homescreen. I read about the rollback. I upgraded my phone via LG Upgrade Tool. That means I have most drivers. The problem is I don't have administrative right on my computer anymore. Is it possible to rollback without admin rights?
If not is it possible to root and unlock the bootloader without administrative rights? Do I need all drivers? Is there an apk to root my phone?
Don't ask about getting the administrator back.

Yes, that's what i did. Also: In general the custom Roms are more powerfull than the stock Rom.

When you unlock your boot loader try to install Magic ROM.It's very fast and its based on v20c.with v20a my phone was buggy.Now it's works great

I'm facing the same issue and I'm running V20C, I was running the 10V version for few days without any problem.
Try to roll back using these methods, I tried it but I failed and I'm still trying

Thanks for the answer! :good: I have adb driver now installed and want to root via All in One toolkit and unlock the bl. After that I download CWM Manager and install it. Then I boot in recovery, wipe and flash that rom right?

I think you mean Rom Manager not CWM
So yes thats right.
If you want any help
PM me

Best ICS rom for P990

Hi everyone
I am searching (and im sure not only me) for a stable every Day use rom for p990.
Mostly i prefer a Rom with the no needed apps removed fir better performance. As i saw there are only 3 roms now based on the stock.
Which one at your oppinion is better?

i'm using topo's build. with v6supercharger.. smooth and nice.. try it..
I think the DjangoManouche is the best at the time we talk..

i am trying now carburano's rom.
it has the supercharged thing too.
ill try this rom for a day then ill see the rom you said.
what is the advangage of the supercharger?
at the old 4.0.4 i has my issue was the AndroidOS, it was wasting me the 50% of the battery

I also believe that the Django ( KingOfBirds Kernel ) is the best:laugh:
i am at his rom right now. verry smoother thn the old one.
but the problem with the androidOS is still there. why does the system needs that much battery?
it should be at the latest line and not at the first
THere is no such thing as the best ROM.

Lg optimus g rom to lg 4x hd

If i extract the custom rom .zip from optimus g and replace the boot.img with a custom kernel of O4X it will boot?
Στάλθηκε από το LG-P880 μου χρησιμοποιώντας Tapatalk 2
Try it and see. I'm sure others want to know too.
Doubt it. If it works there will be problems most likely. But feel free to try, nobody is stopping you, if it at least boots then maybe someone can help you port it properly
Sent from my rooted P880
i dont think that it will work when youvjust replace the kernel, cause the devices aren't that similar. follow a tutorial on xda for porting roms good luck

This may sound like a silly question.... But is this based on the official D955 kitkat stock rom or ported over from one of the other variants?
Guy, he just made a flashable KDZ, then, is not just a stock ROM, it have every single partition, modem, sbl, bootloader, some debug partitions, kernel, system, everything, if some partition is left without flash, the kernel detect and the system don't boot

Because my device is a D958, the only real difference between the variants are the modem, that control the radio, I flashed the D959 ROM but the radio didn't work, then, the D959 modem is not compatible with the d958, I would like to try the D955 ROM, but for this, I need to know if the D955 modem will work in the D958, for this, I just need the modem from D955 4.2.2 and flash it to my phone, then, I can test, if doesn't work, I just flash back my D958 modem and everything is OK.

Guy, I know all this, you are not the first to say, I never say I have a problem that I was not waiting for, are tests, to know about the variants, and I did with other ROM's already, now I'm using a D959 ROM in my D958, any problem, since I flashed the D958 modem on it.
Using a AT&T kernel on it, any problems neither, then, to everybody, everybody can test anything, and say them experiences with it, just don't ask for support after, what i can say is that, is possible undo everything, I just didnt return to d958 ROM because I'm ok with this one.

Downgrade to Jelly Bean , root you phone , install twrp , make a factory reset, flash the attached zip, flash the rom zip, flash the attached zip again and now reboot. Now you are rooted.
