After v18C, now v18D is on LG servers but as usual it can not be downloaded:

http://csmgdl.lgmobile.com/swdata/WDLSW/LGP880/ADEUBK/V18d_00/V18D_00.kdz

I wonder at which alphabet letter they are going to stop and make it public.

[LG Optimus 4X HD] hutjeflut:
right as i cant really find any suitable topics for this and i dont really want to open a new one for it ill ask here.

as many people are updating to v20a i would like to know how much free ram you have without messing with the rom after a reboot.

right ow after i revoor i have about 500 mb ram free and would like to know how much ram remains free after this update.

also as were on it anyway has anyone done benchmarks yet?

thanks in advance.
[LG Optimus 4X HD] RuedasLocas:
Right now, 320MB Free...

why take out the battery?
[LG Optimus 4X HD] RuedasLocas:
Later, we discouver that sometimes its possible the device be recognized with the battery on, and that after the device be recognized

we need to replace the battery.

But even now, sometimes remove the battery is needed for the device be recognized properly to be flashed. Even if we take out the

battery and put it back, sometimes is needed...
[LG Optimus 4X HD] Afro:
I made the experience that removing the battery is just necessary on ICS, I flashed a couple of times now on JB and I didn't need to remove battery and more: If I took out the battery the S/W Mode couldn't be displayed, so it needed to be in... :)

I used the same PC, Flash-Programm, USB port and USB data cable to flash KDZ' for ICS and JB... :D
[LG Optimus 4X HD] RuedasLocas:
Now things are more clear. Even because older users are more experienced and deal better with the device. Before was all that scare of brick the device, etc... But even with JB, when I do several flashes or mess with something OS related, I need to take out the battery sometimes.
[LG Optimus 4X HD] GeBoe:
But my phone doesnt go into s/w without the battery. it does go to s/w when it is inserted.
[LG Optimus 4X HD] pierg75:
I have to say that I have the same experience. Removing the battery doesn't help at all. It goes in S/W upgrade mode only with battery in.
[LG Optimus 4X HD] RuedasLocas:
Maybe latest devices have some changes...

In the beggining worked like that. Now is different for some devices.

Most importante is people find a way how to get in SW, one way or the other.

OK, lets forget about those tiny diferences.

Please guys, help-me.

I buy one P880 from internet, here in Brazil.

I searched in a website his IMEI, and is from UNITED ARAB EMIRATES.

I tryed to update the phone by KDZ, with the Brazilian V10C, but after this, my mobile internet (*3G) NOT WORK. I try another 3 kdz's, and i have no results.

Please, someone help me :(

Tkz a lot, and sorry for my bad english.

Even after flashing official KDZ, still get message about unregistered phone.

Thats because you didn't flash the official version for your device country.

But you can't flash your phone?

Its dev or retail?
[LG Optimus 4X HD] profyler:
retail, comingo from germany, but will flash with brazilian KDZ
[LG Optimus 4X HD] RuedasLocas:
Ahh... the procedure is the normal one, only changes the .kdz

In Brasil the last one is V10B but I think that the V10F works aswell.

If you'l have it from Germany you should have a Open Europe Firmware, try first to change the language to portuguese and see if it works, maybe you only need to root and the update be made with LG PC Suite.
[LG Optimus 4X HD] profyler:
im updating to the brazilian KDZ because theres no brazilian portuguese language, only portuguese from portugal...:(
[LG Optimus 4X HD] RuedasLocas:
Are you sure that the difference is that big??? specialy cause I imagine that the only matter will be on the menus.

The keyboard if you use Swiftkey 3, you can choose the option PT-BR, Google voice to...

By the way, I'm portuguese :) I think you should try it first, than, if you don't like it, you can change, probably you'll do it anyway...

What the difference for v10f
[LG Optimus 4X HD] RuedasLocas:
Chrome as a second browser, the option to take pictures just by saying "cheese" (or something similar to that word).

Updates generaly are to improve hardware functions or correct software issues, no one make them for nothing.

Its up to us decide if we want to test it and use it or not. There's allways a way back to the previous one...

Reebot your O2x in SW Upgrade mode (remove the battery, turn on the device and hold the vol - key)

in this step, should the usb cable already be pugged on the device, or just after?

---------- Post added at 06:48 PM ---------- Previous post was at 06:01 PM ----------

Got it!

screen got grey and blinking even after rebooting device. got scared as hell. Udated now =)

---------- Post added at 07:20 PM ---------- Previous post was at 06:48 PM ----------

i tried to update via OTA , but it says, phone not registered. I registered in lg web site. Should it take a while, or where do i need to register in order to check for updates?
[LG Optimus 4X HD] RuedasLocas:
that happend cause you had no battery on the phone :laugh:
[LG Optimus 4X HD] profyler:
OK, it happened what i suspected:

the phone update itself (not via OTA because it didnt worked for me) to the latest firmware by CHECKING YOUR IMEI. It means that if your firmware is EURO for example, and you install Asian firmware for example, it wont update to the latest Asian firmware, but to the latest EURO firmware because it will check your imei, not the firmware you have.

Thts because the tutorial is wrong:

Reebot your O2x in SW Upgrade mode (remove the battery, turn on the device and hold the vol - key)

dont turn the on/off button, just hold down volume and plug the cable in

He should update this part.

Copy/paste the link and open it with Internet Explorer or Firefox.

Must be some problem with the browser, or, try to do it from other computer.

Its weird... I'm able to download it with Firefox, Chrome, IE and Opera...
[LG Optimus 4X HD] velu99:
I tried other browsers but not able to download, may be related to firewall preventing the port, can anybody help how to resolve this issue?

You can try to set to "recommended settings".

But I think that in case of "block", you should be notified.

Finally I found out issue in hosts, blocking LG site.

I download V10E.KDZ but LG updater says KDZ extract error, and Finished messgae!

What could be reason
[LG Optimus 4X HD] RuedasLocas:
Just exit the program and run it again.

The program extract a temporary .cab file from the .kdz, sometimes there are delays deleting or overwriting that file, thats why that happends, I think...

Its not associated with the phone.

4- Can anyone explain how to reboot in SW Upgrade mode ? I read the guide, but i didn't understand well...

5- I haven't installed anything yet, and i cant see "Modems" in my Device Manager. When i have done all the previous steps, will i have "Modems" in my Device Manager ?
[LG Optimus 4X HD] RuedasLocas:
Its just how to connect the phone.

Start with the process, Windows Enabler", etc...

Take out the battery, press "Vol-" and insert the cable on the phone (already connected to the computer), start the upgrade, as soon as you see the process log running, put the battery on the phone.

Watch this, maybe it will help a little:

[LG Optimus 4X HD] AG22:
Thank you, i do apreciate your help.

So i have to connect the phone to the computer WITHOUT battery, right (pressing Vol-).. So THEN, when the process log running starts, i put the battery back?

I will watch, thanks again
[LG Optimus 4X HD] RuedasLocas:
Right, after you hit "upgrade" on the flash tool, the program will start extracting or unpacking the kdz file that you select, after will start to "write" on your phone, thats when you need to replace the battery.
[LG Optimus 4X HD] AG22:
Thanks a lot, now it is extramally clear! Hey man, i am watching your video right now.. But it is kinda different from the guide xD

yep, press only the vol- buton, dont press the power button or u will get a grainy scary screen

The tutorial is almost perfect. Some mistakes with the "how to connect" and the replace the battery issue.

They don't say that is possible to flash keeping the settings and apps on the phone, or how to do a "clean install" but, for that we'll need a "bible" :eek:

The video was made not only to show how to flash, also to show some mistakes that can happend too...

It could be better but I don't have a decent camera to do it... sorry.

If you're talking about the .kdz downloader for the official FW is here:

To have a better idea you can watch this video:

http://www.youtube.com/watch?v=MZx2zMrLLDo&feature=g-upl

Put in full screen and choose 1080p, HD...

You can see the entire process with several settings/options, and mistakes too...

LG Update is the file named "B2CAppSetup" inside of the "kdz-update" folder. Don't need to be on the desktop. Just put the "kdz-update" folder on the desktop for better access and put FW .kdz file (after download it) inside of it too, by the same reason.
[LG Optimus 4X HD] AG22:
Hi Ruedas!

I have already seen that video in full screen, 1080px. Actually i tried to send a comment. I have watched all the video.

But i still had that question.

But now i know the "LG Update Mobile" is the "B2CAppSetup". Thank you so much.

Ruedas, what is better: Brazil 10a or 10b ? I will downgrade, cause brazil 10c has some bug for root. But when i root 10a/10b, then upgrade to 10c, i will lose root.

What do you suggest ?
[LG Optimus 4X HD] prolux6075:
Nice, but i was unable to download it, maybe is me!!!

If somebody can share the file somewhere else, or at least to write a file list of the .rar file.

[LG Optimus 4X HD] RuedasLocas:
Confirmed!

Brazilian V10C is not "Rootable" (at least for me...)

I spent all morning flashing, changing settings,

EVERYTHING

, and I couldn't root that version...

Tried to upgrade from the rooted V10A, but the root just disapear...

Even when the SuperSU remains it just don't work...

If someone have the solution (tested, not opinions or hints, cause I already tried everything...) I'll be very grateful.

I made step by step, paying very atention, but it couldn't root. I was worried about my phone, but now i am cool ^^

So, i will keep my Brazil V10C without root =/

Do you guess it is better or i should change to 10B/10A + root ?
[LG Optimus 4X HD] Croaker24:
Does V10F work in the Philippines? im not sure if this will change antenna settings etc. help

thanks!
[LG Optimus 4X HD] RuedasLocas:
That depends... If you see some improvement in V10C related with battery, heat, performance, etc... and if you need all those stock apps and, if you don't need to install any apps that require root, my advice is to use the V10C.

On the other hand, if all those stock apps are useless, draining your battery, and, if you need to install some apps/games that require root, my advice goes to the V10B.

Once that you'll be rooted, you can change the camera app for the V10F I suppose, that in case of need, of course.

The rest seems to me very similar, maps, googleplay, and others like, those will update independently of the phone version.

I made a research and im almost shure that brazilian 10c is the same as europe 10f, based on the size of the kdz.

i would stay in 10c, we could have root in future firmware update.
[LG Optimus 4X HD] RuedasLocas:
@profyler, you gotta be kidding...

What size got to do with it?

I'm not saying that they're not equivalent but, don't judge based on file size.

And something different they have, V10F is rootable and Brazilian V10C it's not...
[LG Optimus 4X HD] profyler:
Yes, but you had root in european 10c, didnt you? that doesnt mean a lot.

Size does matter, of course, we have improvents in firmware upgrades..

I explained my thoughts on the other topic:

I`ve made a research and found out that all latest firmwares have a 20mb difference from the previous lates one

Example:

7 BAL/BALTICS	V10B	LGP880	441.62 MiB	28

8 BAL/BALTICS	V10D	LGP880	443.02 MiB	86

9 BAL/BALTICS	V10F	LGP880	461.15 MiB	189	~20mb

15 BRA/BRAZIL	V10A	LGP880	450.19 MiB	54

16 BRA/BRAZIL	V10B	LGP880	450.18 MiB	50

17 BRA/BRAZIL	V10C	LGP880	472.01 MiB	44	~20mb

39 NEU/EUROPE OPEN	V10A	LGP880	436 MiB	91

40 NEU/EUROPE OPEN	V10B	LGP880	441.62 MiB	59

41 NEU/EUROPE OPEN	V10D	LGP880	443.02 MiB	431

42 NEU/EUROPE OPEN	V10F	LGP880 461.15 MiB	1306	~20mb

52 GRC/GREECE	V10A	LGP880	436 MiB	3

53 GRC/GREECE	V10B	LGP880	441.62 MiB	4

54 GRC/GREECE	V10F	LGP880	461.15 MiB	31	~20mb

63 IDN/INDONESIA	V10A	LGP880	436.56 MiB	13

64 IDN/INDONESIA	V10C	LGP880	436.88 MiB	20

65 IDN/INDONESIA	V10E	LGP880	458.8 MiB	19	~20mb

67 ITA/ITALY	V10A	LGP880	436 MiB	9

68 ITA/ITALY	V10B	LGP880	441.62 MiB	3

69 ITA/ITALY	V10D	LGP880	443.02 MiB	14

70 ITA/ITALY	V10F	LGP880	461.15 MiB	170	~20mb

check it out:

Do you see that is always ~20MB difference from the latest one , to the previous latest one (doesnt matter what countie) ?? and very less MB from 10a to 10b or 10d or 10e

I guess asian 10e is equal to european 10f and brazialian 10c, based on the size of the updates they have

Im not saying im right, but thats my guess. I will be almost 100% certain when 10g comes out.
[LG Optimus 4X HD] AG22:
What will be the best for the battery: keep my 10C without root and with all stocks apps OR 10B rooted, removing all the useless apps ? I am not decided yet about what i will do.
[LG Optimus 4X HD] RuedasLocas:
Now I don't remember in what version they start to include "Chrome" (V10F I think...), only that app is 18.99 MB... soo, only that app is enough to give the ~20MB difference, unless the upgrade was only to include the browser, proves that the improvements didn't take more size. Looking at V10D and the next one V10F the difference is less than 18.99MB, less than "Chrome" size...

And Euro versions are all rootable.

Its only my opinion :angel:
