[Q] Further steps after unroot and CWM - LG Optimus 4X HD

Hello Users!
I've got ICS 4.0.3 V10h. I've unrooted my O4X and got CWM.
My three questions are:
1. What should I do next to unlock the bootloader?
2. Is it really necessary to be able to load custom roms and / or mods?
3. How can I update to official rom (if ever ) to JB if my phone is already unrooted?
Thanks in advance for any answers or links

Every rom or mod have specific requirements.
They are specified in the tutorials, soo... The answers for that are on the tutorials.
You can be a nice guy and ask mods to close the thread, or wait until it starts to be useless and flooded and someone report it to be closed .

Tip, do not flash after that a custom ics. Stock is far the best. And the real thing is comming very soon.
ICS Repack Problems
Hi all,
I managed to flash ICS Repack by Chainfire on my galaxy note today. It is pretty cool and really fast. But I've few questions to ask regarding this new ROM. Please be kind enough to direct me to a appropriate thread if these questions are already been asked and solved.
After I flash ICS Repack, I cannot find CWM anymore. What happened to it ? and how I can get it back ?
How I can go back to my old GB rooted ROM (I've CW backup of that rooted LB2 GB ROM) ?
By now, this ICS version cannot render South Asian languages. but LB2 rendered it very well. Are there any option to get that language support on this ICS ?
I need to change this Keyboard (Chinese) to English. Any other method to change it (Instead of installing GO Keyboard) ?
In our county phone numbers have two formats (our numbers are start with "0" but receiving calls don't have that starting "0" ). But in this ICS ROM, those 2 numbers are Identifying as two different numbers. Any method to fix that issue ?
Can I get my CPU speed to 1.4GHz again ?
Please be kind enough to help me on these matters.
Thank You.
This is why users should study BEFORE they flash. Anyways. Flash CWM, boot it, resrore backup. Cant help you much. Just got my Note happy studying

Thanks ... !!!
Stick with GB for now...people working with ICS around here like to make you jump through hoops just to get your phone to work...so if you're not will to spend the time on it, then stick with GB...no fuss, no muss.
The answer to 3. is a very simple 'yes, you can always go back'.
Also, massive thanks for updating your OP with the answers you have found. If only all question-askers did this.

Here's what you MUST READ BEFORE YOU START --> http://forum.xda-developers.com/showthread.php?t=1590266
Well , before you start..
You need to root your phone.
Here's how you do it --> http://forum.xda-developers.com/showthread.php?t=1046605
After you root , you need to unlock your bootloader. This is a risky thing and you might lose your phone.
If you do NOT unlock , you can still install custom ROMS but not all of them.
If you unlock your boot loader you can install any and every compatible kernel and ROM including ICS
To know how to unlock your bootloader (READ THE WARNING IN THE FOLLOWING THREAD) --> http://forum.xda-developers.com/showthread.php?t=1481630
Root , allows you to install custom ROMS (i.e custom Android versions)
Bootloader unlock allows you to install custom kernels (recommended if you want a stable ics)
Please post questions in Q&A in the future...

[Q] Rooting and modding xperia TX

Hi,
I've been trying to learn how to root and mod my xperia TX but none of the forum posts seem to answer the questions I have directly, and so I was wondering if someone could clear up some things for me.
From my understanding if I want to install mods (such as the volume key to wake up):
1) I need to unlock my bootloader.
2) Root
3) Install a deodexed firmware and to do that install a custom kernel.
4) Flash the mod I want to install.
Is that process correct? Also, I'm using JB 4.1.2 with firmware 9.1.B.0.411, is it still possible to do the above tasks with that fw?
Thanks

[Q] Advice to unlock/Root GT-i9000 please

Hi all I've not done this before but not noob to the unlocking scene just first time for Android.

What I'm looking to do is unlock it to allow me to use any network (currently orange).
after that I would then like to look at changing the rom or upgrading to the latest Rom's where able for SIII & S4. :victory:
I've spend a while reading other post so clearer than others but none that can help me as I'm having trouble finding the correct Kernel.
Please any and all help would be most appreciated.:cyclops:

Update on advice
Hi thanks for posting advice.
I've managed to unlock the phone by using a combination of
Rooting it with Unlock Root via pc
That gave me Superuser (upgraded to pro for £2)
BusyBox Free, Titanium backup Free needed also
Then I was able to use Galaxy S Unlock to save files to sdcard and unlock to any network.:victory:
Now does this mean I'm rooted and don't have to follow all the steps that the link above advices
no need if already got busybox installed

Thanks for comments, can I ask now its rooted do I need to install anything else to allow me to change the Rom's such as newer official ones or once others are raving about.
Thanks.
updating or changing ROM was easy method but deadly also, wrong move will come to brick fone. if u really hav thought it well, juz follow any instruction on xda regarding i9000 after confirming ur device version, backed up baseband, build number n etc involve.
n now u ll need cwm for flashing. find cwm to gain access to recovery n thats where u gonna flash ur custom ROM, but read a lot before doing it as here in Q & A section, many success, also failure posted here, so be sure to read first mate

I'm referring you to some wonderful threads I've come across during similar quests of my own.

As to what ROM to choose, I seriously like to push my own (eventual) ROM of choice, Mackay ROM (Unless gaming on the phone is your thing, which might bring up desires and demands that other ROMs serve even better.)
Good luck!

Flash a new rom

Okay im new and im looking around to find out how to flash a new rom. So i see the thing is i need
- rom manager
- flash clockworkmod recovery.
- press the button to install new rom
**( of course we are supposed to press the button to backup first. whatever i dont need backup if i have everything on dropbox and netqin sync and from there i can have everything i want at any other phone too. i dont care for settings , they are a matter of 10 minutes to download and setup the apps ).
So i try this thing.
1) I go root my phone and i get the first error. SystemBackupTest fails to run. yes i have done it properly according to the guide.
Ok whatever i think. maybe the guide is too old and jelly bean 4.1.2 20b has issues with that apk. i search around and i find the other way to root my phone. i download this file : http://www11.zippyshare.com/v/50635135/file.html, i go into recovery mode and i press root. success! im rooted.
2) since im new i test it out. i start installing whatever i find in google play and start tweaking things ) then i return it back to stock and do other tweaks. now i search for new rom. i read guides here about several rom. i now try it.
i install rom manager , i follow the guide and get error boot image signature​. ok i press vol down and power button and restart. i check around here a bit about this error. i found this thread http://forum.xda-developers.com/showthread.php?t=2241754. so i see that i have to unlock the bootloader. so i find this thread : http://forum.xda-developers.com/showthread.php?t=2190326. i follow the guide and i fail because i get a message that unlock is denied. searching around i find another thread that sais ROOT MANY ANDROID. oke im confused. i cant find a proper guide around. can we make it a little easier ? can we delete the oldest threads-roots- .. whatever and keep the new ? can we clean up or sort things up please ? the older members of course are pro to all this but the newer ones we dont understand anything. we need one week only to understand where we have to click next......
So for me and any other new guy later on, what do we have to do ? where is a working guide to root the lg optimus 4x v20b and if there is not , then where is a proper guide to unlock the bootloader ? thanks............
Also here ... it sais many many wierd things. http://forum.xda-developers.com/showthread.php?p=35812268
someone sais where is made from. wt ?? the root guide naver said this is actually for japan, or this is for germany or whatever. every search i do i get to read "new" things scattered around. sort things around. delete old useless threads that get nowhere or pin at start the new ones working on the new firmware. am i wrong ?

2) Don't do anything unless you know what you're doing
3) Use search function (I see you did, but still a lot to learn you have)

that didnt help at all....... thanks for moving my thread here, maybe i got dizzy after so much reading and post it there but im still searching ........ Since 8 hours im searching , following guides and restoring ...
i have lg optimus 4x p880. os: 4.1.2 - 20b. can someone tell me at least one way to install a whatever rom ?
dont tell me follow the guide or things like that , im following them. just show me links what to do and be sure for those links that will work.
Ok, I'll help you. There's a thread called "unlock-relock tool". Use it once and you're unlocked. Then get TWRP from the TWRP thread. Install it via fastboot. Then download the rom you like, boot to recovery and flash it. That's all.
And for root: There's two different ways for ICS or JB. Use the appropriate one. (4.2.1 is JB, in case you didn't know.)
I don't have the links st hand, but there's this index linked in my signature...

you mean this forum is only for developers and for developers asking help from developers about how to make their new custom rom ? if thats it , then im sorry ill find another forum to ask help. Maybe you are SO pro that you cant help someone without knowledge to unlock the bootloader. But i dont even see anyone else answering too. Maybe indeed the bootloader of 4.1.2 20b cant be unlocked yet and instead you tell me keep searching. Anyway i didnt put up this thread to fight with random people. I need help. If u actually cant help then thank you ill get help from someone that can. its the help section after all , not the world war z.
Hey, I told you how to do it. It's not my fault if you don't understand the tutorials or the software that the devs provide. It's all written down, maybe you should read it after having some sleep

You can't flash a rom when the bootloader is locked, can you? That would be a surprising fact for me... Guess you did unlock it but didn't know about it

to flash a rom.. yes..
what kind of rom ? is it stock rom ? or custom rom..
stock rom flashed using different tools than custom rom..
to flash custom rom, you need to flash custom recovery first..
to flash custom recovery, you have to unlock the bootloader first...
that's the basic knowledge

vanir rom. cant be more custom xD i pressed: 3845#*880# which is supposed to check bootloader status and gave me the message: error connection or mmi code is not valid.
Now im thinking if i can flash werewolf kernel in use with vanir rom. is it possible or the kernel has to go with specific roms ?
The command you used only works on LG stock roms.
You can use werewolf kernel but you have to use cm10.2 version
