No, because iridakis theard is also in this section.

Hi there it´s not flashable with flashtool...

It works! You have to update flashtool to the latest version first.

Sorry

70 works great on AOKP :-)
[Xperia Arc General] caqo71:
Every BaseBand has its own file libraries (libs), they must to be flashed with CWM after flashing the main ftf baseband file.

go here: http://xdaforums.com/showthread.php?t=1382657

and read some to know what I'm talking about
[Xperia Arc General] joecool1029:
The libs are not always changed with each new BB release. Nobody has compared the libs from 4.0.3 to 4.0.4. I am going to assume they were not changed until someone knows otherwise.
[Xperia Arc General] caqo71:
I think that 70 libs changed from 64, so, it's possibly that they had changed again for 72. But, ok, if for people just works only flashing the ftf, then let it that way.....

There are two 72 Basebands on arc-forum. JKenvin´s and mine. Now i extracted his package LT15_LT18_Baseband_72.ftf. Then i opened the Manifest.mf in META-INF. What do you think i saw? He copied my work:

What do you think? Should i ask a Mod to close his theard?
[Xperia Arc General] jlazkano:
Hello I just flash the baseband, just one question.

What is the difference between LT18 and LT18i?

The "LT18i_BB77_by papayayoghurt.ftf" is for LT18, and my device is LT18i.

Thanks and best regards.
[Xperia Arc General] cUtting_eDge:
There aren't any differences, they're the same. "I" stands for international.

@xSustainer

Do you happen to know where i can find my current baseband (56) in case i experience some problems on bb 77, or if i can somehow make a backup of my current bb?
[Xperia Arc General] prophet_beat:
bb64 libs

Im on cm9 with bb36 and im having big problems with signal and battery. Ive tried basebands 77 and 72 and i get the same problem, maybe even worse. I want to try 64 but i cant find the libs for the baseband which you've posted. Does anyone know where i can find Baseband 64 libs??

Thanks heaps
[Xperia Arc General] mekayzer:
Don't flash the libs, only the bb is needed.

Libs are for GB, not ICS or even JB
[Xperia Arc General] nPingu:
Sorry mate! I apologize for my previous try about the libs! :confused:

Anyway, I flashed them with ics, will it do any harm to my phone?

Thx
[Xperia Arc General] papayayoghurt:
No, you should flash the Libs always. That what mekayzer said is

wrong

[Xperia Arc General] nPingu:
Thank you Papaya!

Just to make this clear is there a post I can look upon to know exactly everything about the baseband??

what will baseband 77 do on .431 with arc kinght kernel?
[Xperia Arc General] buatcintaku:
Re: [MOD] Baseband Collection for arc & arc S

Baseband still same before flash kernel only

72

Therefore I download bb 77 on first page

But after installed baseband still same before 72
[Xperia Arc General] bfbones:
Installed but there is no change from 72 to 77. All works OK!
[Xperia Arc General] buatcintaku:
Same with me

But on default.prob is 587

*i don't know before installed it value on default.prob
[Xperia Arc General] Silesh.Nair:
Did you flash the ftf before flashing the libs?
[Xperia Arc General] buatcintaku:
Before I use 431

And only flash kernel 587
[Xperia Arc General] Silesh.Nair:
You have to flash the ftf, only then will the baseband change. Flashing kernel will not change your baseband.
[Xperia Arc General] buatcintaku:
Therefore I download baseband 77 from here

But nothing change after installed it

I've been using 77 for a month or so now.

(Been trying out all sorts of ROMS, and they all work - must just remember to re-flash the baseband libs after you've got the new rom up and running).

The difference for me is

Turning on WiFi is faster

call quality is perfect - even in places where my friends phones break up

GPS seems to get location quicker.

I know the base-band should only really affect phone radio related stuff, but it seems that the other stuff is some-how linked.

Thanks @papayayoghurt for the excellent thread - I check back every now and then to see if something new is out :)
[Xperia Arc General] alfiemenace:
what shall i use for FXP cm10? bb72 or bb 77? :) or the one from them? :)
[Xperia Arc General] Hotfingers:
Baseband 77 works with CM10 - 137

I've just installed cm10 on BB 77.

It works fine, BUT you have to boot up into the launcher before flashing the base-band libs.

For me the order was: -

Install CM10

Boot to launcher

flash the pdroid patch & boot to launcher to check all still working

flash the fix by besttt & another check that all is still working..

flashed the base-band libs last

Hmmm. Looks like I must update my signature again. :o
[Xperia Arc General] alfiemenace:
what pdroid patch?
[Xperia Arc General] buatcintaku:
i'm confused with function of baseband

but post below make me understand about it

now i try to feel it

thanks

thanks bro
[Xperia Arc General] Hotfingers:
Just a quick answer because we're drifting off topic ;)

This thread: - http://xdaforums.com/showthread.php?t=1719408

It's a windows program that patches the rom. It also creates an "update.zip" that you can flash on the rom.

The patch / update.zip make whatever changes are needed to allow pdroid to work with the rom.
[Xperia Arc General] lawgone:
Does the BB77 in the OP works with Arc too? Even though the file name says LT18i?

Is there any particular method of installing this?

Flash ftf then flash libs right away?
[Xperia Arc General] papayayoghurt:
Yes it does.

Gesendet von meinem LT18i mit Tapatalk 2
[Xperia Arc General] Hotfingers:
Yes it does :D

My ARC thinks it's a LT18i ;).

The kernels and the roms I've tried are not confused - they know to set the default CPU speed at 1GHz so I think the phone is not harmed by this.

I think this should work 100%.

It's usually a good idea to do a CWM backup first in case something funny happens.

Then if the upate fails (bad download or whatever reason) you can re-flash the previous baseband, and do a CWM restore.

For me I've never had to reverse a baseband update.

I've updated my base-band at least 3 times from this thread - Each time the update worked perfectly.

Check Settings->About Phone->Baseband Version. It will show the current baseband your phone has.
[Xperia Arc General] buatcintaku:
Still 72 not 77

But I'll try to feel different about it
[Xperia Arc General] Silesh.Nair:
That means you didn't flash the ftf or the flash didn't complete successfully.

Why flash didn't complete but can operate normally?

What version fw to be flashed?
[Xperia Arc General] panda0:
Long question:

My GSM SIM doesn't work with any baseband under 70 (dunno why). OK.

Now I'm using gingerbread and baseband 77 give me the "insert sim card 2" bug ( eg here: http://xdaforums.com/showthread.php?p=30694281#post30694281 ).

I can't flash baseband 72 of this thread (flashtools doesn't work only with this particular one :confused:).

- Now I'm using baseband 70 with 67 libs.

- I'd like to know if it's worth to try baseband 73 in gingerbread.

I'm lookin' for the best possible battery life!
[Xperia Arc General] Pedram888:
I had 70 on my arc s LT18i.

install 72, 73, 77

all of the worked fine.(tested just for couple of hours) Even without installing the lisb. (on MIUI v4 Rom)

I think I have a bit better signal with 77 but not any noticeable effect on my battery compared to 70.

now installed the libs anyway. but wondering what it exactly does !?

Thanks for the post, by the way ;)
[Xperia Arc General] lawgone:
Thanks people.
[Xperia Arc General] Hotfingers:
Hi Pedram888, I'm no expert - Just a fan of this thread.

My thinking is that the libs give the android operating system a way of talking to the "phone part of the phone".

So it's safer to use these libs if you're not sure.

Just recently I CWM flashed Google apps. Suddenly I could not connect to the cell-phone network! :confused:

So I re-flashed the 77 libs, and my cell-phone was back :D

So I think the libs kind-of complete the base-band. Without the libs you maybe find yourself with a base-band that's "not working".

Then the libs sort you out by fixing the link between android and the base-band.
[Xperia Arc General] panda0:
EDIT...

I was wrong. Even with the new setup doesn't work at all. :\
[Xperia Arc General] Pedram888:
thanks for your reply.

I kindda know that libs interact with the baseband (note) but wondering why it behaves differently on other devices or roms. for example if lib 72 doesn't work with baseband 77, why sometimes it works and sometimes not.

It doesn't matter anyway cuz it better to update the libs if not sure, as you said :cool:

hello guys, i need a help, sorry if my question is silly

i want to install this rom, it's X-Gamer from OmenHTX

http://xdaforums.com/showthread.php?t=1905575

in the thread, Omen said it's better to use baseband .64 for his rom

but when i see this thread, baseband .64 is for LT18i, but my phone is LT15i

is it going to be okay if i use the .64 baseband?

thanks guys
[Xperia Arc General] caqo71:
LT18 is Xperia Arc S

LT15 is Xperia Arc

Both phones share the same hardware, except that LT18 has a 1.4GHz CPU speed. So, Baseband on both devices is tha seme. X-Gamer ROM is based on GingerBread (GB) ROM, so Baseband (BB) 64 is optimal for that rom.

Go ahead. :good:

[Xperia Arc General] filikindri:
A little bit of help, pliz.

I tried, some weeks ago a JB ROM, so I installed bb77 .

But I can't remember if I installed LIBS+ftf , just libs or just ftf).

If i watch: settings-about the phone it says BB77.

Now, with JB or ICS Roms, 3G drains battery. So, I want to stabilize that:

Android SO information about BB, is related to libs or to ftf? How can I know what BB and what libs my phone has?

I have read BB77 drains much more battery than BB72. ¿Could I use BB72 with JB?
[Xperia Arc General] Destroyedbeauty:
Yes, BB72 is the only baseband that I truly can recommend for stable compromise between battery life / signal reception on the Arc / Arc S! :)
