Question about custom rom and Baseband - LG Optimus 4X HD

Hello xda Community,
I've downgraded the baseband on my p880 to v10h due to some issues with GPS and provider signal.
I've used some custom roms before and the issues appeared at some update when I was on MoKee rom but I can't remember which update it was. The downgrade improved the phones performance and I have no issues with GPS and signal.
My Question: If I Flash a custom rom, - will it also update my Baseband? Say I'll flash a 4.3 Rom (I'm currently on 4.0.3) will it update my Baseband aswell to v20x?
Thanks in advance.

Don't think so. I haven't even really seen any indication that the community understands HOW to update the baseband firmware. This phone has the radio on an entirely different chip with dedicated flash and ram for it. There are soft switches to throw (look but do not touch) in the hidden menu that switch the USB port over to it for flashing but nobody seems to know how to make use of that knowledge other than the official LG utilities. Flashing a third party ROM is entirely about replacing the unencrypted/unsigned partitions on the main application processor's flash.

[Q] newbie again

Hi all
I am just getting a head of myself here but I am wondering if I can learn before I start flashing my LG O2X.
I am in Australia and I am wondering which firmware (full stock) is most preferred at the moment?
I read in the firmware sections and it seems as if the not all stock firmware are very stable (Some people are complaining that it sucks out of the juice badly).
so any suggestions (links will help heaps) is much appreciated.
any link to good tutorial to flash the firmware is also greatly appreciated.
Thanks
sorry for the newbie questions

Cheers guys!
I am still confused with all this term of base band and firmware used for LG o2x.
On my Samsung if i want to update my stock firmware i just need to go to samfirware download the latest one . Open ODIN as the flashing application, put the downloaded firmware package and press start.
Is this the same process in LG?
Do i need to root first? Where can I download the latest firmware package for LG?
Thanks again guys

Hello!
This depends...
If you only want the latest firmware provided by LG - just use the LG Update tool, follow its instructions and click start - wait a few minutes and voila.
Only working with an unbranded phone of course - in case of a branded phone you might have to wait for the OTA from your provider.
But you might have to wait at least another 6 Month for the next update from LG - last Update by LG(in Nov.) was to Android 2.3.4 and still has some bugs - ICS(Android 4.0) is in the making but...
If you want root, a custom rom(I would say CM7 is a lot better than stock rom - my opinion) with all the latest updates(i.e. Android 2.3.7 may be an ICS-build for X-mas ) and/or an OC/UV kernel it is a little more complicated.
Thanks for the prompt reply.
So... it sounds like the CM7 has won lots of hearts.
If I want to update mine (stock unbranded), which tutorial should I use?
since I am completely new to LG, any step by step (from the beginning) tutorial will help greatly.
I am after total stability and good battery - I am only using camera/video recording, playing videos, musics, skype/fring/viber and also some small games like angry birds etc.. good GPS lock is a bonus.
So any recommendation is greatly appreciated
Thank you

Frist things First - backup all you date before you start because the phone RAM/ROM will be wiped!
If your phone comes with Froyo (Android 2.2.2) you could go right ahead and start after the ***-line
...if your phone comes already with GB (Android 2.3.4 – look under setting on the about page!) you need to smartflash a CM7-compatible baseband (i.e. 0725 for Froyo or 0823 as I use it).
Guide to flash baseband – only needed if your phone some with GB(Android 2.3.4)
http://forum.xda-developers.com/showthread.php?t=1008070
A German guide with downloadlinks…
http://www.handy-faq.de/forum/lg_op...-lg_optimus_speed_p990_aktuelle_baseband.html
If you try the newest baseband on this page (0823 – 23.08.11) you must flash all 4 files in descending order of filesize – the others are single files which are easier to use.
***************************************************************************
The easiest way would be to root the phone with SuperOneClick.
http://www.xda-developers.com/android/superoneclick-updated-to-2-2-now-features-zergrush-exploit/
…and then use Clockworkmod (http://forum.xda-developers.com/showthread.php?t=1098745) or Rom Manager to flash the latest KANG, since there aren’t any up to date Nightly’s because the CM7-build bot server is broken.
A Guide is in the Wiki pages for the LG P990…
http://wiki.cyanogenmod.com/wiki/LG_Optimus_2X:_Full_Update_Guide#Method_via_ROM_Manager
You could use either one of these KANGs…
Rusty:
http://fitsnugly.euroskank.com/gigglebread/p990/
temasek:
http://www.mediafire.com/temasek
koboltzz:
http://www.4shared.com/folder/9Y9RYzQA/_online.html
Don’t forget to flash the latest gapps for GB 2.3.7 (right now AFAIK version from14th Dez.)– you can find them on temaseks-mediafire account.
Just place KANG-Files and Gapps on your SD card before you enter boot recovery.
At the end you need GetRIL or LG RIL versions from the market to update you RIL because the preinstalled baseband of you new phone is almost probably 0725 and CM7 comes always with 0218 – just download GET RIL and hit the install button…
Now you should be good to go.
If you are even more adventurers you could look into the ironkrnL for more performance/powersaving – see my sig. and/or look in the ironkrnL-Thread at xda and flash an ironkrnL after the gapps.

So “only” about everything one could do with a Smartphone…
Latest ironkrnL-builds with 00 or 32 ramhack should do it(stability and good battery) - but you might need to set the ring delay between 3000-4000 in the build.prop found in /system (you need a root-capable filemanager/editor i.e. ES Datei Explorer (https://market.android.com/details?id=com.estrongs.android.pop or Rom Tool from the market). I had a problem with the preset delay of 225.
Hope that helped...

[Q] Problem with call sound quality

Hey guys,
my girlfriend has a i9000 Galaxy S which has a lot of problems with call sound quality. When Incall the sound starts normally and then suddenly you hear some kind of noises, like radio interference (all kinds of creeking and various sounds). It will start and stop randomly during the call. This happens no matter where she is (in the apartment, out in the open, etc).
She is currently on stock Android 2.3.3 (non-rooted)
Baseband I9000XXJVO
Kernel [email protected] #2
Build number: GINGERBREAD.XWJVH
I wanted to ask how I can fix the problem? I have an Optimus 2X and I'm comfortable with it, have changed roms, flashed basebands etc on it, but I'm not sure if its the same for the Galaxy (although I suppose it should be similar).
Do I need to change baseband, ROM, Kernel (or all three?). and if so, which ones should I choose? She is an average user so she doesnt need something with high performance, just something easy and stable. I especially didnt see a thread for basebands and how to change them.
All your help is very appriciated. Thank you
I just saw the thread in this forum (was looking at the developers forum before) and saw the post with firmwares, basebands and instructions), but the question still stands:
what combination do I choose of baseband and rom, and do I take the stock rom or one of the custom ones (has to be very stable)?
Thanks guys
Guys? Noone?
Rather than messing about flashing
Modems, I would take the opportunity and flash stock jvt or the latest stock jvu and see if this fixes the problem, if it doesn't, there is probably a fault with the phone.

That is just the rom, or?
Yeah, just flash a whole new rom, jvu is the latest and is pretty good.

Official Update to Android 4.1.2 on N7000XXLPT? S-Pen issues!

Hello everyone. I just brought an Note with BB.N7000XXLPT, Kernel/Build XXLQ3. Unrooted with Android 4.0.3.
KIES and OTA says I have latest firmware, but I read that NOTE`s latest firmware is Android 4.1.2.
How can update to official Android 4.1.2 without rooting? Is that possible?
Now, my S-Pen is not work correctly. Sometimes works, when I press hardly, but very rarelly. Touchscreen display works just fine. Is that a common issue, is pen broken or is because Android ICS 4.0.3?
I`m new on this, just pls. help.

Where are you from? Maybe the JB update isn't available for your country until today.
You can install a Stock JB Rom (one of the official releases) with PC Odin.
Install JB and test your pen again - then you'll know if it's broken.
10x for quick answer ThaiDai. I`m from Romania. And I think the update is not ready here (it comes very slowly from carriers).
Pls. can give me advices how to install latest official stock Android with Odin, without rooting (I mean, i hope kies and OTA still working after).
Links, tutorials or something?
I just tested s-pen with testing tools and is working chaotic.
10x in advance. Jim
Dr. Ketan's thread is the thing you need.
Follow the installation steps in 1a and 1b.
You can try XXLSZ from Germany (download links in his thread).
How about S-Pen, what do you think, is a common problem or is my S-Pen broken or an 4.0.3 issue. How can I fix this?
And btw, on step 1b says to flash an custom kernel (PhilZ) first and then flash stock kernel. This make device rootable and KIES and OTG will not be available? (Allshare and Radio too)?
I try all day to do something with S-Pen, but useless. S-Pen works time to time and need really preasure to write/draw something. Sometimes I hope not cracking the display with that high pressure. I read tons of threads but never find someone with this issue. Mostly have issues with to sensitive pressure and 2mm inaccuracy (present in my case too). Help pls?
Did you install another Rom and check S-Pen after this?
ThaiDai no. I just stay on stock 4.0.3 what comes with the device. I just can`t understand why bunch of ppl over internet has problems o Note 1 with to much sensitivity at S-Pen, an I haven`t it at all. I need to stab the display to draw a single dot.
Install JB and test your pen again - then you'll know if it's broken.
You should try this first - from lamenting it will not get better.
I`ll try somehow to test my s-pen on other device or some othe s-pen on my Note to test it. If I can`t, device has guarantee certificate and that`s why I don`t update to JB, temporary. Is very strange tho...
You don`t reply to my question. If I want to update to JB, need to install (PhilZ) first and then flash stock kernel? This make device rootable and KIES and OTG will not be available? (Allshare and Radio too)?
10x in advance ThaiDai.

And you don't read what is written there. No stock kernel but a stock rom is installed.
But why do you ask JB installation questions when you do not want to install JB?
So use your certificate and let Samsung repair your device or pen
I`ll do that. And if my problem is fixed, after I`ll try an JB Rom. 10x ThaiDai.
ThaiDai, installed 4.2.1 official germany stock via Odin and works great. This week I'm going to Samsung service to solve my SPen problem.

Solved S-Pen problem and now my Note with official kies Android 4.1.2 work almost great (a little exception with battery fast draining).

Newbie needing Baseband help...

Hi all,
I have just flashed CM7.2.0 which I downloaded from the official CM website....the flashing everything went fine but it seems unstable signal wise, high battery useage and also trying to turn on and off Airplane mode it sometimes wont work without a reset of the device. I was thinking possibly a Baseband issue?
The only thing I have no idea what baseband I am meant to be running on Gingerbread CM7....I was on the stock LG ICS rom before flashing. It says my baseband is currently 1035.21_20121130
Can anyone recomend the correct baseband for me?
Is the one above left from when I was running ICS?
Am I correct in thinking when flashing the baseband stays as it is....it doesnt come with the new rom?
I am sorry for all the questions but need big help.
Thanks
Tom

Flashing a custom ROM cannot change your BB. Your BB presently is the ICS BB and ICS BB are always not supportive of the GB systems and communication.Your battery drain signal, drops, maybe because of that too
So, you need to change your BB to a GB BB as the CM7.2 is gingerbread stuff.
Changing the BB is only possible with smart flash or KDZ method. Please check tonyp's Baseband thread in the development section for all the answers for BB.
Hope this helps

[Q] android and radio clarification

I need some clarification regarding android and radio baseband.
I'm running latest cm-11 nightly and my baseband version is XXUEMK1
Is this radio included in the cyanogenmod ROM or is it a separate partition that wont get updated with a ROM flash?
I've found the thread with a list of different radio ROMS for the i9305. Are these optimized for different countries or will they work regardless of country?
Is there a way to backup my current radio if I want to try a different radio and need to revert? XXUEMK1 is not listed in the thread with all the ROMS.
Found some information in another tread:
Baseband / Modem / Radio - This is the software that manages your connection to wireless networks, be that voice or data. Unlike unrooted users, you can download and flash any number of i9300 (Versions for other models WILL BRICK YOUR PHONE) or i9305 radios pulled from official ROMs. I wouldn't waste too much time on them. Usually what your official ROM comes with in your country / for your carrier, is the most optimised for you. Try a few by all means but don't waste time testing every last one.
Be aware that Samsung official ROMs come with a baseband. Often this means Samsung based custom ROMs may also do so. Some ROMs which install using the Aroma installer (A kind of set-up wizard) may give the option to not flash the baseband. AOSP ROMs almost never come with a baseband. When you flash a ROM withotu a baseband, the previous baseband remains. You can by all means, mix and match ROMs and basebands. You are not tied to the baseband with the same build number as the ROM. For example, if you are on XXEMB1 ROM, you definitely do NOT have to stay on the XXEMB1 baseband.

I've kind of same issue.
My SIII LTE is working fine with CM10 but when I upgrade to CM11, it doesn't work anymore :crying:
I've almost everything working apart from the MODEM and for a phone, I'm sorry to say that it is annoying
I'm using my S II with OMNI ROM and I miss my S III :crying:
Any help will be welcome :good:
I attached a screenshot of my system.
