1st thing: nvflash does NOT flash baseband! You have tou flash a nvflash ROM (GB or CM10), then flash baseband with smartflash. Then flash 28g version.

2nd thing: i souldn't do this, but ok... there you go link
[LG Optimus 2x] hugoqueiroz94:
Thanks, I managed to get into the CWM by rom manager.
[LG Optimus 2x] wkpark:
I got the same error :)

just dump your bct and using it to solve this problem.

nvflash --bl fastboot.bin --read 2 bct.img
dd if=bct.img bs=1 count=4080 of=bct.dump

and...

I just found a new method to flash/change bootloader

all partitions are preserved except UDB(UDB randomly erased/corrupted)

http://xdaforums.com/showpost.php?p=33939677&postcount=620

you don't have to worry about formatting /data partition anymore
[LG Optimus 2x] cmahendra:
generally you should download, check md5 checksum and then flash if md5 is ok.

useful link for windows users to quickly check md5 in context menu (right click on filename)

Is there a way to enter CWM when the phone is off? VOL DWN + POW doesn't work anymore.

I flashed with NvFlash.
[LG Optimus 2x] Stefan Gündhör:
Funnily on my phone it works in some cases and in some not.

I found out that you need to press POWER first and instantly aftwerwards VOL DOWN. But POWER first. Then it works for me.

Also if it still doesn't work make sure you booted your phone once before doing this.

[LG Optimus 2x] wapz:
This is a bit annoying indeed, because normally I do a rom backup, install baseband, and recover backup. Now we have to do a reinstall everytime and go through nvflash, smartflash, nvflash. Do we know why Smartflash is broken? wkpark, do you know?

Please Stefan type in Installation instruction that we have to flash FIRST BaseBand then via NVflash flashing the ROM

CWM works regularly here, just have to hold power+vol down a little bit longer. CWM pops out as soon as LG with open padlock disappears.

Still have to test baseband upgrade via smartflash, will report later.

Update: smartflash (s/w upgrade) mode doesn't start, display just flashes once when connected to PC. Windows doesn't detect a connected device.
[LG Optimus 2x] petr.klos:
Okay.

True dat.

I had to. May be useful. Free space, free world. You cannot do anything.

Anyone tried any more demanding game?

Anyone had any problems?

Aaaand I am leaving this, for it is not very well documented. :) I wanted to know what changes/"optimizations" were made, for me to be sure whether the problem originates in SG work or in LG work. To be sure.

Bye Stefan's ROM, you are not useful to me, and thanks for all the fish.
[LG Optimus 2x] deniskimpe:
so now i am on the nvflashed version but with the older baseband from the 28e leak, i also tried smartflash to update the baseband, but doesn't work neither... i'd like to reinstall the smartflash version of the 28g leak but i can't use the smartflash, what to do ??

LG PC Suite 4 for P990 ICS extracted from v28G

Windows only.

Download: http://d-h.st/x5Z (105.72 MB)
[LG Optimus 2x] wkpark:
I have no P990 but with P990's unlocked/cracked bootloader + SU660

S/W download mode work perfectly

- Pull out your battery (disconnect USB)

- hold down volume down and connect USB until S/W download splash

- insert battery again (to protect accidental USB disconnection)
[LG Optimus 2x] Stefan Gündhör:
For me it works as well on P990! I would like to know why for me and not for others.
[LG Optimus 2x] Imperticus:
Can someone quickly confirm to me how many files are there in the xbin folder on V28g? Thanks :)

in original stock 2, because no su binary

busybox is located in bin not xbin, just to mention
[LG Optimus 2x] patedit:
I flashed V28E with NVFlash yesterday and today I flashed V28G using CWM.

I didn't have any kind of problems in both cases. For now, V28G works perfectly for me but I have only been using V28G for 30 minutes... I will keep updating!
[LG Optimus 2x] wapz:
Doesn't work. Never get the SW update splash screen. NVflashed to v10b and it worked again. Maybe after NVFlash of v28g it works again, didn't try yet (was coming from v28e).
[LG Optimus 2x] Imperticus:
Thanks. I'm out of my 8 daily allowance. I extracted the system directly from the v28g.bin and thought there was error, but seems its fine.
[LG Optimus 2x] Stefan Gündhör:
I did the same :) Quite cool! Built my ROMs out of it.
[LG Optimus 2x] hugoqueiroz94:
What the diference between 28E and 28G?

Anyone else have poor performance with this rom?
[LG Optimus 2x] diaramja:

[LG Optimus 2x] patedit:
Not in here. Everything is smooth. Everything works perfectly so far. Not battery drain (because of wifi mainly)...
[LG Optimus 2x] kayuz:
but can you nvflash?:confused:
[LG Optimus 2x] diaramja:
No.

:(
[LG Optimus 2x] klappstuhl218:
Thank you very much for this awesome mod!

Nice to have CWM and root with this leaks. CWM is working as intended for me. I have the smartflash problem too, but I guess you will find a solution for this issue quickly.

V28g is almost flawless for me. It seems even faster than V28e. And it looks like LG finally found a solution for the WLAN bug when the phone lost mobile network after WLAN was active for a while! :good:
[LG Optimus 2x] trocopassu:
Well .. for now everything works reasonably ... unfortunately still not working the "smartflash"! I do not understand why?! ...

I leave some images after flashing version v28G.
[LG Optimus 2x] jmsmartins:
Doesnt work for me either.. tried with and without battery. Even tried vol up instead of vol down :D

You have to install APX driver and follow the instructions of post #1.
[LG Optimus 2x] deniskimpe:
Can(t even connect to my google account, the server doesn't trust the connection or something it says. But how can i smartflash the 28G version from this point with the nvflash version i have now ?
[LG Optimus 2x] arrediabo:
not quite sure i understood what you asked.

What i said was: I installed the NVFlash version of v28g and smartFlash does not work.

If you connect the phone while pressing + & - at the same time, the screen will remain black. If the drivers are properly installed, you just have to double click the flashme.bat that comes in the 7zip archive you downloaded

---------- Post added at 12:15 AM ---------- Previous post was at 12:11 AM ----------

use nvflash to revert to an old one (I used this one) then you can use smartflash for whtever you need.

SMARTflash is not the same as NVflash
[LG Optimus 2x] m4rkiz:
"or something" :P

happened to me yesterday as well, not sure why it is working now anyway

[LG Optimus 2x] coolacrille:
Coming from old partition format I did:

1. Smartflash V28G BB.

2. NVFlash V28G.

3. After first boot, shut device down.

4. Attempting smartflash for testing purposes, cannot go into download mode.

I know this thread isn't for commenting the actual ROM or BB, but damn I got perfect signal on H in my apartment.
[LG Optimus 2x] smokku:
Drop --odmdata 0xC8000 from command line and it will work just fine.
[LG Optimus 2x] Stefan Gündhör:
I think I goddamn FINALLY found out how to use Smartflash again (workaround):

Boot your phone, connect to PC, select USB mode "Charging only"

Shutdown the phone, disconnect, remove battery, connect in SmartFlash mode (VOL DOWN + plugging in USB)

Done :cool:

PLEASE TRY AND REPORT
[LG Optimus 2x] arrediabo:
is "loading only" the top one? (I'm with portuguese language, so i don't know for sure) If so, smartFlash still not working.

EDIT: switched to english, didn't help. Ther is no "loading only" options are: charge only; mass storage; media sync; usb tethering & LG software

During this message the phone goes to S/W upgrading mode.

What should I do ?
[LG Optimus 2x] coolacrille:
I'm afraid it doesn't work after doing that either. And for anyone wondering it's the one that says "charging only" in whatever language you are using.
[LG Optimus 2x] spyrosk:
There is no Loading Only. I tried it what you said with "Charge Only" and "Software LG"

It doesn't work

BTW is there a possibility that the SOS partition should be kept at the original size and not sized according to the recovery image?
[LG Optimus 2x] petlo99:
does everybody changed the partition or kept the gb one...?
[LG Optimus 2x] Stefan Gündhör:
Being afraid does not help. Testing does.

But you are right, it's "charging only" in English!

Oh accidentially I wrote "VOL DOWN + POWER" but it's just (VOL DOWN + plugging in USB)

Here is what I did: first it didn't work (SMartflash mode) - then I booted, set to "charging only", shut down, battery out, connected and it worked
[LG Optimus 2x] Micronuub:
Why want to use Smartflash anyways for flashing a new BB?

Why even flash a new BB gb Bb works fine. :)
[LG Optimus 2x] trocopassu:
Ya...i no...but don't work too:(:crying::crying::(!...
[LG Optimus 2x] hakankarani:
Can't get into smartflash either...is there any way to flash latest baseband v28g without it?
[LG Optimus 2x] Stefan Gündhör:
You are right the good thing is there won't be much more new basebands. LG will drop support and BB development once ICS is out. So one doesn't need to change frequently.
[LG Optimus 2x] optimusG:
It doesn't work here. I want to flash the 28G BB with Smartflash and I can't. :( Is there any workaround on how we flash the new BB? NVflash version or something...?

PS Great job Stefan!
[LG Optimus 2x] arrediabo:
as it was said earlier, you really don´t need to flash a new baseband.

But if you must, nvflash to a previous ROM (you can use this one); then smartflash the required bb and then, nvflash the v28g again.
[LG Optimus 2x] rendex:
up please
[LG Optimus 2x] Stefan Gündhör:
You could also try multiple times, does that work? There must be a reason why I can Smartflash ... Maybe I just have a superior phone :D

This did not help either, was bit scared when it did not power up even after NVFlashing.

1) Then searched for PaulBrians V10b NVFlash and flashed it. Without booting into it, tried SmartFlash, now it worked.

2) Flashed V28G Baseband in smartflash.

3) Flashed V28G Rom in NVFlash. And the device is back to useable now.

Dont know if it will go back in Smartflash again or not. Will report after half an hour.

[LG Optimus 2x] SamS1989:
if i first installed the v28e, and after your v28e with nvflash, and now flashed v28g with nvflash, i need to flash the baseband, or the nvflash version include the BB ?
[LG Optimus 2x] kt-Froggy:
OK, sorry -- my bad. Although, to my defense, this is the reason I got confused:

In the topic's title, it also says [UNBRICK]. Now, I always thought that, if a ROM is described as an unbrick tool, it should include everything, including a coresponding BB, i.e. to be a complete self-contained package. I may have made a wrong assumption, then. Will keep that in mind from now on...
[LG Optimus 2x] smokku:
Baseband is not a part of the ROM.

It is a software for second microprocessor dedicated to radio communication, that talks to Android through interface called RIL.
[LG Optimus 2x] SamS1989:
thanks a lot :) and sorry the question. i will remember :)
[LG Optimus 2x] klappstuhl218:
I celebrated too early. :( The bug is back for me too. It lasted for nearly two hours and it never worked for such a long time for me, but in the end I lost the egde connection again. I'm on BB V28g too.

But I think I found the corresponding error message in the radio log:

11-12 23:26:52.670 E/GSM ( 456): [GsmDCT] onDataStateChanged(ar): No associated DataConnection ignore
11-12 23:26:52.710 E/GSM ( 456): [GsmDCT] onDataStateChanged(ar): No associated DataConnection ignore

I managed too reproduce the issue three times and when the phone looses the connection I allways get this two errors.

I can post the whole log if anybody is interested.
[LG Optimus 2x] mivv:
@Stefan

can u make a flashable zip of the basebands?
[LG Optimus 2x] kt-Froggy:
I know that... :) I was just under impression that this NVflash package would include it, similar to how the original KDZ from LG does. Anyway... I was wrong, it's explained in the first post (should have read it carefully to begin with), all is clear now. :)
[LG Optimus 2x] Netuser:
BB can't be flashed using CWM you need to use smartflash
[LG Optimus 2x] Stefan Gündhör:
Did you ever hear of a baseband that bricked the phone? :)

Or did you hear of a baseband that unbricked a phone? :)

If 2x no, then this is the answer why BB has nothing to do with and in an "unbrick" ROM.

[LG Optimus 2x] Stefan Gündhör:
a deodexed version of v28G CWM Zip + a deodexed NVFlash version - both with some additional (previously missing) LG widgets, ported from SU660 (not by me) - have been added.

I needed to patch the LG keyboard app so it can run on deodexed ROMs.

Also in NVFlash version the Linux installer is fixed.

Stefan, since stock ics are resize in partition. If ppl wanna go back to CM10 but still wanna maintain this resize partition. Can u make a nvfalsh for it? So we don't have the worry partition. Tks

[LG Optimus 2x] DrummerMuppet:
CM10 uses the old partition layout, so it cannot be done (unless RC decides to use the new one).

You can, however, increase the size of the system partition. Find owain's thread on the Development forum to find out how.
[LG Optimus 2x] orbital_71:
I understand nvflash are powerful tools too much use of it will harm the phone. Just wish we can use one type of partion so we can freely move from this ics and CM10. :)

Since the leak Stefan had been busy working it. Just wonder whether he ever sleep? :confused:

BB 1120
[LG Optimus 2x] Stefan Gündhör:
No, sleep is for the weak :cool: :D

Now I'll go watch some movies :good:
[LG Optimus 2x] kt-Froggy:
How??? The physics of flashing process doesn't change, whichever tool you use. True, there is a higher probability of someone screwing things up with NVflash, if they don't know what they are doing, but that's another story. Technically, using one flashing tool or the other doesn't increase the chances of damaging your phone, as far as I understand it... From the end-user standpoint, it's a matter of a flashing method being most convenient and most foolproof (well, within reason).
[LG Optimus 2x] hugoqueiroz94:
What the advantage of deodexed rom?

The lg keyboard was fixed on 28G deodex?
[LG Optimus 2x] Stefan Gündhör:
deodexed = .apks can be easier modified (good for ROM cooks and modders) and more free space in /system partition. google the rest ;)

I did fix the keyboard so it works deodexed, yes.

I have been looking in this forum and I didn't find that someone has already posted this. I don't know if it is a well known LG feature... but there is a HiddenMenu activity.

You can access this activity dialing *#*#880#*#*. It is for testing porpuses.

I can see that there are some tests that are not implemented yet. Actually, if you try to launch them you will get a toast "Not implemented yet." <drama>Would it mean that V28G is not the final release? Whatever! lol</drama>

How do we install the add-ons from OP? Is it simply installing the apk's from the phone itself like a regular apk game,and the zip files flashed to CWM? Hoping for the quick response,it does not say it on the OP so I do apologize if this has been answered already. TIA!

Stefan can only have the CWM for people like me who had already unlocked the bootloader so we can flash in the future version of the ROM zip that you have announced, or even just to make a backup before making any changes or experiments? Thanks in advance

Inviato dal mio LG-P990 con Tapatalk 2
[LG Optimus 2x] DrummerMuppet:
If you want to avoid answering this very question over and over again, add it to the OP under FAQ or something similar. I'm sure many people will ask "what if I want to roll back to [insert old-bootloader-based ROM here]?" in the upcoming hours / days / months / years / centuries :p
[LG Optimus 2x] Stefan Gündhör:
New bootloader and layout are still very *new*, that's why there currently don't exist any ROMs you could flash with the CWM of this ROM. You can flash app packages and stuff but nor ROMs or ICS kernels not made for the new bootloader.

But restoring is possible:

- you are on CM7/10, make CWM backup, save backup to pc

- you flash this ROM with NVFlash, decide to go back to CM10 with NVFlash again and there you can flash your CWM backup you saved on your PC before.
