[BASEBANDS][TUTORIAL] Freedom! Choose your baseband. - LG Optimus 4X HD

Up until now, this topic has largely remained in the dark. Not anymore however!
I have figured out how to flash different basebands onto our phone. Unfortunately, at the moment, doing so requires a "factory reset" of sorts, and you will have to re-flash the recovery image and restore your nandroid backup afterwards.
I look forward to finding a better way, but this will suffice, I think, if you, like me, have had terrible GPS problems.
The main use for replacing the baseband is bad GPS signal. Best results have been reported using the ICS basebands for people with trouble getting a signal / finding satellites.
!!DISCLAIMER!!
This is probably not for the uninitiated. It will most likely be fine, but I give no guarantees whatsoever. I paid attention when putting this together, but the only baseband I have tested myself is the V10H - EUR, that is currently running on my phone.
If you end up without IMEI, unable to make phone calls, your phone doesn't boot, I am not responsible and might not be able to help you.
I HIGHLY recommend you have your bootloader unlocked before you try this. I don't know if it will work with a locked one, it might, but I wouldn't try it.
However if you pay attention, are careful and follow instructions, you should be fine.
Pre-requesites:
Hex Editor (I use HxD in windows - http://mh-nexus.de/en/hxd/)
LG Flash Tool with working drivers (please see this great tutorial by SnXo about it: http://forum.xda-developers.com/showthread.php?t=2179126)
Model firmware (See below)
Baseband you mean to flash (See below)
Tutorial:
Download and extract the "Model firmware" and the baseband you mean to flash and place them under a folder named Baseband
Open the Hex Editor
With the Hex Editor, open the baseband file.
You will see a bunch of numbers and letters, nevermind them. Just make sure the first four blocks of the file are numbered 30 12 95 78, they should be, if not STOP and use another baseband. Also warn me so I can correct it,
Now that you have all selected, right click, select all and copy.
DO NOT CLOSE THE HEX EDITOR.
Now open the model firmware file (it ends in .dz)
Open the search dialog box. You want to search for "INSERT" and datatype "text string" - should be in a drop box somewhere.
Now you will see on the left a bunch of Fs with INSERT FLS HERE in the middle. Select everything between and INCLUDING the first and last F on the block. (the first and last block should be addressed 2484 and 24D3, respectively).
Right-click and paste
If it warns you the file size will change, say you're okay with it.
Now save the file and call it "Flash.dz"
MAKE SURE YOUR BATTERY IS WELL ABOVE 50% BEFORE PROCEDING!!
Now flash the .dz file you just created with the X3_v0.0.7.4.dll using the LG Flash Tool as per instructions here: http://forum.xda-developers.com/showthread.php?t=2179126
Congratulations! You are now running the baseband of your choice. Let it boot, root it, flash the recovery, restore your nandroid and presto!

!!ALTERNATE METHOD FOR JB BASEBANDS!!
The tutorial above is the only method available to flash ICS basebands at the moment. To flash JB basebands, however, if you prefer, you can grab the full roms from here (the corresponding countries are between parentesis above):
http://lg-phone-firmware.com/index.php?id_mod=15
and flash the .kdz file with LG PC Suite hacker or KDZ flasher. You can find more information about that here:
http://forum.xda-developers.com/showthread.php?t=2134192
http://forum.xda-developers.com/showthread.php?t=2069723
Then just proceed to root and flash your nandroid backup as usual, The baseband will be kept.
Thanks to Flying_Bear for reminding me to include this method!
Commentary and what to expect:
Using the 10H baseband did wonders for my GPS. It might do for you to if you had great GPS on ICS but not on JB. Different region basebands might make a difference too, I'm not sure how they differ from each other.
I am not a developer, just a user like you who had a problem and decided to tackle it in the ways he knew. If you want to help or have any relevant input, please don't be shy, I will listen and be greatful for it.
You might have noticed there is a short list on the ICS baseband side. That is because there are many more left to add but I didn't want to delay making this guide any longer.
Also, I will try to make an executable to automate this byte replacing process, but make no promisses. My coding skills are limited and so is my time - if you'd like to do it, feel free to do so. I'll put your work here and give you full credit!
If you're an advanced user or developer, wondering about RILs and whatnot, don't change the RIL. I'm not sure it'll work for every single baseband here, but for the 10H - EUR, the 20A - EUR and the 20B - HKG it works fine. Changing the RIL breaks the phone and you have to restore a backup.
The basebands were extracted from .dz file of stock firmwares downloaded from the LG website. The name is that which is in the .dz file after extraction from the .kdz and the basebands listed differ in md5 checksum from each other. How they are different, I have no idea.
I'll put a FAQ up with the most asked questions, if there are any.
Cheers!

thanks for this, i have pretty crappy gps on any of 20x variations, so i'll try ICS baseband either tonight or tomorrow. thanks again!

Will flashing a different baseband resolve baseband wakelock which is a big battery drainer on my LG?

also, a tip - you dont need to use lgflashtool to change basebands between 20x versions - you can flash kdz trough lg pc suite hacker or kdz flasher, then restore your nandroid backup. the method described here is useful to get 10x basebands, since you cant just flash kdz to rollback to ics.

I'm not sure, give it a shot. But I believe that is a different issue that is kernel related.

Thanks for the tip! Actually, I am aware of that. It's just that I really like LGFlashTool better. Also, thought it would be a good idea to systematize the different basebands availible under one flashing method, to be less confusing, and to save the good people downloading some bandwith (5 mbs baseband vs. 500 mb full rom). Also, it's a complex method, but at least it's just one!

for me, lgflashtool seems like a hit and miss, i had some issues gettting it to work right now. flashing the modified .dz with 10h bb atm. i agree it's better to have unified method, the kdz one can stay as an alternative to people who have bunch of kdzs lying around (like me, had 20a & 20b leaks, 20a eu, 20a esa & 20b hk, tried all of their basebands and gps locator was slower than what i remember on ics) or dont feel comfortable working with flashtool, or have issues with it etc.
edit:
flashed modified .dz, no issues as of yet, gonna restore nandroid backup now (first root & recovery setup, /yawn), and we'll see how it goes

Let me know if it works for you! I had some luck with the HK 20A baseband, but the 10H really fixed it for me. Also, added your method to the original post

A proof it works I'll test gps tomorrow to see if i have improvements. Thank you!
edit:
actually, just went to my windows to test it lol, got a signal in under than a minute, while it took over 10 on JB baseband. thank you again

Very nice work! Can see that a lot of research went into this.
Will give it a try later.

Did you try to flash only baseband naming it *.fls? Very nice work! Thanks for figuring this out.

Well, so which baseband is the best? Anyone could test?

Why is there no way to flash a new baseband like flashing a kernel with flashing in cwm?

I wonder this too...

I have seen that not everybody has problem with baseband wakelock. In my country,I know people that dont have baseband problems so I thought it might be a thing with baseband version..That would be easy fix,just flash the different basebad and problem solved!

Unfortunately renaming the file .fls won't work, the process will fail, and I know why. The LG Flash Tool needs a proper header to know where to place these files. Removing the other parts of the .dz file and keeping the header won't work, and I really don't know where to find documentation on this. This process is possible for example on the LG Optimus 2X, because there are effective tools to unpackage the .wdb file (contained in the .kdz) into separate parts with the appropriate headers. For the .dz files our phone uses there is no such tool, and the headers between the files show no resemblance. This needs further research!

Of course this was my first approach, as you will see if you check my thread on general asking for help. To flash something in CWM you need to know what files you are replacing, where they are and what partition they belong to. This is possible for example on the Nexus 7 3G or the HOX. However, on our phone, I was unable to locate the baseband files, and as far as I can tell they do not belong in any partition CWM can write to. This seems to be the way LG phones are designed, as it is the same for the LG Optimus 2X. I might be wrong though, so figure it out if you can

I'm living in Portugal and so far have excellent results with the V10H-EUR baseband, both in terms of GPS and 3G signal. So seems to Flying_Bear. But there are so many, who knows which one is the best? The more we try the more we'll know!

Dumb question.
Would flashing a baseband help with my lost IMEI?
My phone died and after recovering to CyanogenMod, and then back to stock, my IMEI has disappeared. I've tried flashing Cyaonogen nightlies but it hasn't worked.

I would need more information, but that would seem the effects of a corrupt baseband. You should flash a fresh .dz or .kdz file and see if it fixes it.

It is also possible that AT&T told LG not to put the kdz file up on their server. I know certain phones that that do not have the stock image allowed to download.

If you have a friend with the unbranded p920h, yes. Otherwise we're unfortunately in the same boat with a missing paddle. :-\
Sorry for the double post, but If you flash the V21A euro over it you get the euro baseband. So, we're either struck without root (unless we can convince some root gods to visit us), be lucky enough for an LAM exploitable firmware or have a euro GB bin for the V21A fall into our laps (we could flash it over the V20A LAM). Ugh....
Edit: Note, I'm decent at kernel building but not good at the base level stuff such as rooting. I wish I was....
tell me what file you need?? i download a lot of files and keep in my pc, maybe i have the file that we need.
From what ive read and tried you have to get the cab file from the kdz then open the wdb file but there is no way to open it all the lg utils things require a inf_webdnld.dll that our cab file does not have. I spent most of yesterday trying to open it with no success. But in that wdb there should be files that make up the bb we need
LG Thrill 4G on O3D GB
Exactly. We actually need at this point the bin zip as it had the bin and fls files. Though through downgrading and upgrading, I have a feeling the LAM GB baseband is similar to the froyo basebands. I've bin downgraded and it works with froyo, the LAM GB but not euro GB. I'm also working on the back end with someone on a possible V20a root as well.
any luk wit te bin zip???
Have u tried rooting v20a with superoneclick 2.3.3

No luck. Tried. Reaching out to someone else to see if there are alternatives.

Possible way of getting ROOT + 4G (HSDPA) speed for p925 (rogers or at-t)

Hello everyone, I know post are existing in the development section for this but I think I may have a way to get 4G speed on p925(g) (rogers optimus 3d and at-t lg thrill) combined with root.
EDIT #2: If kdz flashing worked for you but isn't working anymore for no reason, please read this before asking : http://forum.xda-developers.com/showthread.php?p=22023493&posted=1#post22023493 lg effers blocked the acess to kdz flashing since their last version updater
I'm not a pro Dev but mods will be happy, before posting I READ and try to post something usefull.
As I was searching a way to get a better bb for my rogers optimus 3d I found many interesting things but all were uncomplete.
1. The LG Optimus 3d seems to simply be a LG thrill (don't be fooled by the G in P925G it seems many ppl are just ommiting the G to do shorter)
2. This post : forum.xda- developers.com/showthread.php?t=1449021
(pull off the two spaces after xda-)
Showed me that there was a working stock gingerbread ROM from Brazil that is having the right frequencies to give 4G on rogers (tested by myself and it's a GO!) and on at-t.
The only problem with this rom is that currently There seems to be no way to root it (not even the latest superoneclick 2.3.3 can do it).
So basically it's not that bad because you've got the choice of getting STOCK GINGERBREAD WITH 4G SPEED ON P925 by flashing v20a kdz (follow first link)
But many of us want to get further. ROOT + 4G is almost a requirement for a phoen to be respected according to me and many other.
So acording to the post there is 4 THEORETICAL ways to get root + 4G on a p925
1. Follow the instruction in the post, and if you're one of the lucky bast**ds for who the second kdz installation doesn't push the european bb well you're good to go but even after 5 times repeating the process the bb was always getting flashed.
2. Get the superoneclick guys craking, so we can get Root access on the brazilian ROM
3. Get who knows who cracking the brazilian or european kdz file to isolate the bb (from brazilian) or the ROM (from european) and then flash them in the according order to get a rootable ROM + the brazilian bb together (we know they are compatible since bast**ds from #1 are still getting data).
4. Install only the ROM from someone who would post an european .bin (without bb) of v21a to be installed over the full brazilian kdz.
So basically i'm widening the call for this .bin file search but I think there might be another way!!!!
I've seen phones reacting different ways when combining a froyo baseband on a gingerbread ROM.
a. the phone bootloops
b. there is no signal but phone boots fine
So basically if the p925 is doig b. it would be possible at the place of searching a v21a bin (that seems hard to find) flash a rootable froyo bin . So I'd like to know if any of you still have one of the rootable bin that were found in this post : forum.xda- developers.com/showthread.php?t=1246678
I would have already tried for myself but since megaupload closed fileserve does not support share anymore....
So if someone could provide me with
a. one of the rootable .bin file in this post :
forum.xda- developers.com/showthread.php?t=1246678
and I'll tell ya if it's a WIN or if we have to get back craking!!!
b. Tell me if this workaround fits:
1. Flash V20a brazil kdz (found here forum.xda- developers.com/showthread.php?t=1449021
2. Flash a rootable froyo .bin using this method
forum.xda- developers.com/showthread.php?t=1244490
3. Root the froyo ROM
4. Install CWM
5. Flash a gingerbread rom made for p920 NOT FOR p925
6. TELL US THE RESULT!!!
BE SURE TO KNOW WHAT YOU ARE DOING BEFORE FLASHING KDZ AND BIN FILES... I'M NOT RESPOSIBLE FOR ANYTHING HAPPENING TO YOUR PHONE. BUT IF AS ME YOU GOOGLE AND READ YOU'LL PRETTY MUCH ALWAYS FIND A WAY TO UNBRICK... DON'T ASK I WON'T DO THE GOOGLE FOR UNBRICKING YOU!!!
so I know it's a long post but.. I prefered to go into details and expose my point right with all the sources article
Good luck to all and KEEP ON CRAKING!!!

[Q] Different versions of the same firmware

How can I change the versions of firmware I have?
Right now i have the romanian version of the GB update and I want to install the europe open version do I have to do anything different from the regular procedure?
Thanks in advance.
you must download and install the European firmware with installer KDZ
Look into my noob how to and follow the second guide with the R&D tool procedure. Plus of course you need the v20n europe open firmware. Google for it. This way you will get europe open, although I dont see the advantages of it...
After using it for a week I found out that my screen on time went down to 3h from 4h-5h and I would like to switch back to v20n.
Thank you very much.
Related to your guide i have another question though
To unroot in a way that is harder for lg to detect it all that I have to do is update using the R&D tool?

Yes, and delete files from SD card. Of course, use the Software, that you can also get from B2C. But I guess you can also simply make an emergency recovery with B2C and then perform another factory reset from within the phone, just to be on the safe side

dont know what to do, trying to factory reset it still unknown baseband.
tell me what to do to get my baseband works again
thx
Are you sure, this is stock software? Looks like CM7... Dont you have network at all, or what's the problem? Can you get a hold on any software in KDZ or .bin/.fls format? If yes, why dont you try to flash it to your phone? Did you maybe accidently enable flight mode?

yes i dont have all my network
this is my first marquee i have it from ebay.
dont know if it's CM7 but i think it's stokrom
i try to enter recovery it's on blue recovery without any dalvik wipe.
just wipe data and cache and reboot.
i try kdz method using KDZ_FW_UPD_EN on this site never load to flash the kdz file it's always run on normal boot, i try 5-20 second still missed the flashing mode, im hopeless
can you tell me what i'll have to do?
You need to use the KDZ workaround in my noob how to. Hmm, could you post another screenshot maybe, where I can see, if it is v20x or v10x or CM7.
You could also go here: http://forum.xda-developers.com/showthread.php?t=1692191 unpack the kdz to bin and fls files, patch it with CWM, flash the software with smartflash (look into my noob how to for more information, see 3rd post), make a full wipe, once ur in the recovery menu, flash superuser.apk and see if it works then. If not, you at least have a rooted phone already and are able to use the RIL changer (look in playstore).

N00BY0815,
I also found I have unknown baseband (suddenly the phone works well). I am now on v28c and eagerly waiting for your v30b repack to give it a try. But before I do it, just a question - will you fulfill your promise to provide a flashable baseband (http://forum.xda-developers.com/showpost.php?p=35429425&postcount=675)? If so, I would prefer to wait, since this probably would be the most comfortable for me - have your flashable repack and baseband.
EDIT: Don't bother N00BY0815, I'll flash fls as you advised in another thread

[Q] I9070P flashed with I9070 ROM, how to downgrade it to GB?

I've flashed my I9070P with I9070 JB russian ROM (I9070XXLPZ_I9070SERLPZ_SER from SamMobile site) and bricked it ofc. Warranty service wanted me to pay over 150$ for new motherboard, what is pointless with so cheap phone, so i've decided to not fix it. The funny thing is, that when i got back the phone, it actually work, but the phone "think" that it is I9070. Not everything works well and it's terribly slow. There's about 0.5 - 1s lag after pressing each button on a screen. My question is - is there any way to get it back to GingerBread? I can't find any downgrade solution for I9070P and I really dont want to brick it again. I would be very grateful for any advices
After *#1234# I get:
PDA: I9070XXLPZ
PHONE: Unknown
CSC: I9070SERLPZ
I can give you any additional info if it's necessary. cheers
So youre the first one running jb on 9070P
Search the forum for proper firmware and apply downgrade tutorial for non-P version
tapatalked
enjoy the jellybean goodness.. try factory reset..
i think I9070 and I9070p have different pitfiles or partition on internal storage..
not quite sure if it can adapt pitfiles of the former..
if you could hold on for a second before downgrading - you could test some things for other 9070P owners
could you try to root your device using the i9070(non-P) way, as specified here: http://forum.xda-developers.com/showthread.php?t=2087424 ? and then try to replace /system/lib/tee folder with files coming from s3 mini NFC version? I posted it on my dropbox: https://www.dropbox.com/s/33xwln0d13uhfvq/tee-s3mini.zip - ofc don't forget to set proper permission - in gingerbread they are rw-r--r--
why this? actually replacing /system/lib/tee folder is the way to make custom roms from i9070 and i8160 to work for i9070P and i8160(NFC) respectively. currently we don't have any sources of /system/lib/tee folder from i9070P as no JB rom appeared yet, so "borrowing" it from s3 mini _could_ be some sort of solution
I don't if cwm/twrp backups do include the bootloader, but in case you'd need a "clean" TWRP copy of working gingerbread i9070P rom (no data) - I can provide you with that. maybe that would help better than odin flash
Maybe, if it's the only one I9070P with JB on the world, I shouldn't touch it at all, just sell it to some museum or smth for a lot of money
@adamuadamu
Ok I'll try to do what u said but... well, it looks like some serious action, i'm not sure if I can handle it. It would be much easier if you write me the same thing in polish on priv, then we post here what we get
PM sent in our native language.
waiting eagerly for the results

btw. can anybody tell me if there's rw access over adb to /system partition in stock recovery? I remember first frapeti's deodex scripts and they were able to make changes on /system partition within stock recovery. as pstysz wrote he wasn't too proficient on rooting and /system editing stuff, maybe it'd be the easiest way to provide him with a plug-and-play (plug-and-pray ) script.
I have copied most of the partitions (small ones, all except cache, system and data) from the phone. GB versions. If you need bootloader or something (except efs) then I can try to create a tar.md5 for you.
I can also give an experimental JB kernel built for i9070p. Never tested of course.
I'm in touch with the OP through PM.
replacing /system/lib/tee files didn't change anything. still modem says "unknown"
And he's willing to test some more things - any ideas?

Try those tee files from sola. See attached.

I hope the OP follows his thread and will try that one and let us know
the other thing is the system drains the battery in 5-6 hours, as the user reports. can you post your compiled kernel, too? I suspect this may be similar to gingerbread, where i9070 kernels caused excessive battery drain when flashed to 9070P
dw, I keep an eye on that thread
@LaizyJumper
There are files with "test" postfix and normal ones, should I copy them all together?

Here it comes.
Just remember that it is never tested. And I have never built kernels for such devices before.
If that does not work then I can try to create a downgrade pack for i9070P - GB. Similar to i9070 version.
Edit: removed the attached kernel - it did not boot

I think it does not hurt if you just copy all of them as they are... I don't really know how those files are being handled / loaded.
Edit:
Here is a pack of files similar to I9070 JB > GB downgrade. Those files are taken from I9070P packages and device.
Nothing is tested. Use it at your own risk.https://dl.dropboxusercontent.com/u/64321967/I9070P-recovery-files.zip

Hi, those "tee" files from sola did't change anything, modem is still "Unknown". After changing kernel for i9070P-not_tested-4.1.2-kernel.bin.md5 i cant't even boot my phone It goes in a loop, show Samsung logo for a sec and then reboot. The good news is that I still can run odin mode, but recovery doesn't work for now.
edit: oh, and thx for the downgrade pack!
Ok. Thanks for trying. At least I know now that kernel does not work. I will remove it from here.
You should be able to recover 9070 Jb kernel using Odin if you want that. But it won't make the phone usable of course.

No problem, too bad that did not work out...
I think that phone is cursed or something... I can't even downgrade it. It hangs on Samsung logo, even though I proceed exactly as in "How to Downgrade JB 4.1.2 to GB 2.3.6" topic. Ofc I used files for I9070P. The worst thing is, that I can't charge battery now, so I don't have much time for experiments. Could you help me for the last time?
Have you tried loading an official firmware for your device with Odin?
Firmwares from sammobile.com
Maybe it works after all those steps now. Don't activate repartition option when you load it now!
Btw. does it display I9070 or I9070P when you turn it on? Was it different before the downgrade procedure? I assume that this screen comes from bootloader. And it is important to know which loader is actually present now.
Unfortunately it doesn't help. It shows I9070P but it was like that all the time, even with JB. I think the service fixed bootloader, then saw the flash counter is >1 and send me back the phone because I didn't want to pay for new motherboard (which was the right decision imao). So they left the previous ROM and changed only loader. That's why it worked.
