[SOLVED] New owner questions - LG Optimus 4X HD

Greetings everyone.
As the title says, I'm a new proud owner of this phone and wish to tinker a bit with it, to smooth out performance and battery life (specially the latter). I am currently navigating this forum to find answers to all my questions, and am only creating this topic as a "fail-safe" to assure I find (and understand correctly) the answers I'm looking for.
First, the beast:
Android Version: 4.0.3
Baseband: L620_MODEM_SIC_02.121601
Kernel: 2.6.39.4
Build: IML74K
Software Version: LG-P880-V10h-NOV-19-2012
Probably too much info, but better safe than sorry. I've found [URL="[/URL] guide on rooting and [URL="[/URL] bootloader unlock (although I'm unsure if I'll use it for now, I'll play around with stock for the time being).
Now, here come the questions:
1. Can you only install CWM \ TWRP with an unlocked bootloader?
2. [URL="[/URL] CWM says "only for 4.0.3", does it mean that it can only be installed in that version or will it only work with that Android version? (EXTRA: if there's any better recovery alternative that I've missed so far, please do point it).
3. I'm planning on using CPU Controller to set my max to 1.2Ghz (have a Vita, so the phone won't be used for gaming), I shouldn't have any issues, but a confirmation would be nice nonetheless.
4. After rooting (and mayhaps bootloader unlocking), could I safely update to stock JB? Would I lose any of the procedures if I did?
As I said, I'll keep lurking around to try and find an answer to these questions. Thanks in advance to anyone who replies.

Firstly u need to update to official JB to unlock the bootloader & then root it & install CWM, since ICS bootloader can't be unlocked so no custom kernels.
1. yes u can install CWM with an unlocked bootloader
2. CWM & its procedure to install on ICS & JB is different.
3. No issues when you underclock your phone.
4. Yes after rooting ICS also you update to official JB.
Lastly i would recommend you to first update to official JB, then root, unlock bootloader, install CWM & then finally go with all roms, mods & kernels.

First off, thanks for answering.
Can CWM only be installed with an unlocked bootloader, or can I add it without having to unlock? That was more the point of my question.

You need UNLOCKED BOOTLOADER in order to install any custom recovery like CWM or TWRP. The best way to install CWM is Rom Manager from Play Store.
I have already answerd most of your questions with proper links availabe here on XDA here is the link http://forum.xda-developers.com/showthread.php?p=42058399#post42058399

That's all I ever needed to know, many thanks! The order was confusing me (coming from a LWW, where you could install CWM without unlocking), and I didn't want to mess anything up. Time to fire up the JB upgrade.

Upgrade from V10D to CM10.1

Hi,
I am still running stock ROM (rooted but LOCKED and NO Recovery) and I would like to upgrade to CM10.1 Official.
I been reading around but there are so many methods to upgrade and unlock and root and stuff and a lot of users having issues, therefore I would like to know which method would be best to:
1. Unlock Bootloader
2. Install CWM
3. Upgrade Firmware to V20A
4. Install CM10.1
5. Any other cool stuff?
Anyone willing to help please? I don't need a long reply with details, just links to the best method thread of doing it would be great thanks! Too many methods around.
Regards
All the guides you need are here: http://forum.xda-developers.com/showthread.php?t=2225910
First upgrade to JB, then unlock your bootloader using official method, if the official method doesn't work try this: http://forum.xda-developers.com/showthread.php?t=2251407
Easiest way to install recovery is through ROM manager available on Google play, you need to root before you install it though. After that you can use recovery to wipe data and flash cm10.1, good luck!
I also recommend you install this kernel with cm10.1, it gives extra governers, schedulers and overclocks the GPU: http://forum.xda-developers.com/showthread.php?t=2256899

Flashing from unlocked bootloader

Hi Guys,
I have read a lot of the threads but I cant seem to find the right one, perhaps there is a guide that I cant find?
Anyway, I have an xperia Z on stock I unlocked the bootloader a few months ago without problem but I never got round to flashing a rom, now there seems to be a lot more to choose from I would like to flash, but theres a few things that are slightly confusing me.
1: Can I just flash any rom because I have an unlocked bootloader?
2: if yes to question 1, could someone please point me to a guide.
3: do I need to root to be able to flash a rom?
4: if yes to question 3, please could someone point me to a guide
5: Do I just need to use flash tool to flash a custom rom?
6: if yes to question 5 please can someone point me to a guide? (I found a guide in the general forum, but it only refers to flashing a stock rom, abd I am interested in custom roms)
7: Am I miising something completely?
sorry for all the questions, I have previously flashed roms on HTC and Samsung phones but this sony seems a little different.
I would greatly appreciate any advice you can offer.
Thanks
1. Yes (http://forum.xda-developers.com/showthread.php?t=2153167)
3. Yes (http://forum.xda-developers.com/showthread.php?t=2154310)
You can also use (http://forum.xda-developers.com/showthread.php?t=2186423)
5. Flashtool is used for flashing only stock roms and kernels (custom kernels (Unlocked BL) or stock (Locked BL), You should use recovery to install custom roms (link in 1)
7. Yes you are - the kernel. Hope you would be moving to CM or AOSP, in such cases you should flash their respective kernel before flashing the rom. Refer to link 1. The kernels will be provided by themselves and you can also use flashtool to do the same!
Hit THANKS if I helped!

Comeon..... Go to dev thread all instructions are very exhaustive and if u have a unlocked bootloader why to worry..... Flash any rom u will be fine... U will find all instructions clearly laid down
Unlocking your bootloader allows you to use the likes of cm 10 and as op also it i is then very easy to install roms, if you ever have to recover with flashtool ftf then after completing you just flash dooms kernel and then there you have cwm, rooting is very easy doom lord created a self rooting zip which you flash in cwm. No more flash ftf, root, install cwm. Also you are able to factory test / wipe cache in cwm because dooms kernel will just rebuild files needed
a lot of custom roms are already prerooted I think there are 2 which isn't, 1 is zeroinfintitys

how to root i896

hey guys just grabbed this samsung galaxy s captivate from a friend whos dad found in las vegas sooo i guess its mine now, i have no plan on using it as my phone just for developement but i see that this is the rogers version (i896 while the at&t is the i897) and the forum only has it for the at&t version so im guessing they can use same root methods and use same roms correct? i see that a 2.3 update rolled out for it via kies but this one is still on 2.1 and i saw you can only root it on 2.1 and 2.2 so im staying here for now, i was guessing that superoneclick or gingerbreak could root this phone so ill try them both. one last question is there a better version of touchwiz ported to it? like galaxy s2-s3 look and feel? if now i was hopeing to get CM 10.1 on it, ccan somone point me in the right direction please?
Edit: i rooted it with z4root and was successful, i tried to get CWM on it but it seems that Rom manager dosent support andrid 2.1, and if i do get rom manager on here is there one for my i896? or do i just use the at&t cwm?

Yes, same device, different branding, better modem/radio. You can flash anything found here, and some from the Galaxy S i9000 section. As for rooting:
1. Grab a kernel for your current ROM version. I think the latest Rogers ROM is KH2, but you'll have to check on that. If you're not on it yet, grab this http://hotfile.com/dl/130585492/8ca639c/SGH-I896_RWC_I896UXKH2.rar.html (pass:sampro.pl), and flash it through Odin(I'm not sure if its included. If its not, google for it. Odin 1.83 or 1.85)
2. Flash it through Odin
3. Reboot into recovery, flash http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip
4. You now have root. Mod all you want, and proceed to flash yourself to JB 4.3, or any other version you want

I'll do this after school, and so I don't understand this fryo and eclair boot loader thing. Also can you show me the stable cm10.1/10.2 ROM please? I looked on cm and it was messed up for some reason
Careful with flashing ROMs with bootloaders!
Bad flash may brick your phone with no DIY solution.
- Update to 2.3.3 via Kies (install correct Samsung drivers first, follow the instructions)
- Reboot to make sure all is OK
- Go to Download mode, Flash Corn kernel to get CWM (find it in attached guide, read carefully and install correct drivers)
- Reboot to make sure all is OK
- Download CM10.1.2 Stable + Gapps, copy to your Internal storage (not SD card)
- In Recovery, do Factory Reset, Clear cache, Clear Dalvik
- Flash CM10.1.2. stable + Gapps (follow the instructions in the guide, no root needed to flash custom ROM)
- Enjoy rooted Android 4.2.2

Best use Windows 7 computer, Apple users report issues.

thanks for this! going to update it to gingerbread when I get home, I see that I have to flash a kernel in order to get root and CWM, this would have to be my first time so I hope I don't screw up xD I still don't quite know what kernels are even though I have been rooting/flashing for a long time. I have Hard bricked soooo many of my Samsung devices, like 2 or 3 and I wanted to cry when I bought my GS2 xD.
The good news is that Captivate is hard to brick. The only critical part is bootloaders update. Leave this task to Kies, millions of phones got updated this way (including mine). Yes, there are reports for bricked Captivate after Kies, but hope everything will go smoothly. Just follow Samsung's update instructions. Google what Kies version is recommended for Captivate update (i don't remember, sorry). To update to latest stable CyanogenMod read the guide and follow the instructions closely. You'll find inside the links to one-click Corn kernel update. Careful with Heimdall drivers, they are for a specific USB port (it is explained in the guide). Again, no root is needed for upgrade process, only CWM. CyanogenMod comes rooted. Good luck!

It's a hardware modification. No use to do it now on a 3y old phone. Just update your phone to a stable Android 4.2.2 build and go light on apps and data. Don't expect much from a single core CPU and limited RAM phone. Nobody ever expected that Captivate Android development will go so far. Use what you got and upgrade the phone when you need more muscle.

Help with changing from 4.1.2 to 4.4.3

Hello, I've just bought i9305 with Android 4.1.2 (so no KNOX, no root) and I'd like to get newest custom KK.
I've found this link - http://forum.xda-developers.com/galaxy-s3/general/ref-understanding-basics-rooting-s3-gt-t2362743 but I wanna know if I understand correctly:
1. I do backup, especially /efs through recovery.
2. I do root so:
"a) Download the Latest Odin
b) Download recovery of your choice (I choose CWM) and flash it via Odin" - my question is where I can find the latest CWM for i9305?
3. Now I just flash any 4.4.3 soft? No need to flash any older rom before?
That might be a bit newbie questions... I knew everything on my old phone (SGS1) but now I don't remember these steps cuz I did that long time ago on i9000.

I had a Galaxy S i9000, a Galaxy S2 i9100 and now I have the S3 LTE and the steps where all the same.
I rooted mine with an app called 'framaroot' then installed mobile odin, flashed a CWM recovery, downloaded the rom I wanted or needed and the gapps for aosp roms... and bam... I was on 4.4.2 kitkat!
Tried many aosp roms but all of them had problems with music. It's stuttering. So I got back to alliance 4.3 and wait for (hopefully soon) 4.4.2 official!
Maybe you could get help on YouTube. There are many tutorials and instructions.

Steps for Switching Rom
I am currently using Cm11 on sony xperia sp, I have a unlocked BL and root access.
I would like to switch to a new custom rom now like XperianZe. I tried also, and in the process i bricked and also had a bootloop.
Can anyone please explain the detailed steps to do a fresh install to a new custom rom like XperianZe.

Just follow the mentioned instructions in the respective thread. And as for Xperianz as you mentioned, you have to read this post.
Based on the post, it seemed the installation is straight forward. What makes you have a bootloop? Did you flashed the kernel mentioned in the thread via fastboot?

yes, you guessed correct. i tried flashing the kernel. And the phone didn't start at all.. not even power up.
Later i read a post in XDA, in which it was described that i should do a hard rest by pushing the hole button at back and then try to boot.
Tats when i got boot-loop. I again flashed the custom kernel (DooMLoRD) and did installed CM11 again using CM recovery. Then the phone booted cm 11.
I followed this link and tried doing so. which resulted in phone not powering up and then boot-loop.
So now if i install Xperianz ROM following instruction in this link, it should be working properly correct?
Am sorry if am asking dump questions. Now am a bit scared to try to switch to this cutom ROM as i may end up bricking the phone again. The thing is I really don't want to mess it up again.
I am new to rooting n playing around with custom ROM. CM11 was my first try and was a success in first go.
Thank you for helping me.

I am concerned about how you flashed the kernel. How did you flash the kernel provided in the thread? Did you use adb or FlashTool?
If you want to try any other you can use Existenz as it require only the stock kernel.

I used FLashtool to flash the kernal.
If my understanding is correct, As of now i am not on stock kernal. When instaling CM11, I flashed the kernal of DoomLord for getting CM 6. recovery.
If this is the case should i flash the stock kernal first and then give a try for Existenz?

Well Existenze require most Sony things out of the box, so you'll first need to have Stock ROM in place before flashing it's ZIP. I've dug through the Xperianze thread for you and seemed like your problem is not to be found in the thread. If you really want to try out Xperianze, you might want to flash the kernel via fastboot using adb, rather than Flashtool.
