Creo questo topic per aiutare tutti coloro che hanno bisogno di cambiare baseband per migliorare il segnale e la qualita delle chiamate.
Prendo spunto da un topic, del forum internazionale XDA Developers, di Tonyp. Il link é questo: http://forum.xda-developers.com/show....php?t=1658047 .
É in inglese, non ho veramente tenpo di tradurlo tutto. Se avete problemi chiedete che vi tradurro cio che volete. SE QUALCUNO MI AIUTASSE E MI TRADUCESSE UN PO DI COSE MI FAREBBE UN FAVORE.
Su XDA mancava un thread aggiornato sulle baseband e quindi tonyp, autore del porting delle paranoidandroid, e ha creato uno.
Qua ci sono delle domande(Q&A aka Faq) la cui risposta si trova nel secondo post.
Il Q & A attualmente elenca le risposte alle seguenti domande:
* Che cosa è una Baseband?, che cosa è un RIL?
* Quale baseband è il migliore?
* Come faccio a installare un RIL?
* Quale RIL dovrei usare? Devo installare un RIL corrispondente?
* Aspetta, che cosa è SU660?
* Aiuto, la mia baseband è indicata con Baseband? Unknown
* Come posso vedere che baseband ho attualmente installato?
* Perché perdere il mio RIL dopo aver flashato un aggiornamento della ROM?
* Perché della mia chiamata la qualità è cosi bassa? Perché la persona dall'altra parte sempre sente un rumore fastidioso statico?
* Perchè ho un timeoffset dopo aver installato una nuova Baseband??
* Che cosa significa "(V10b, Europa)" ecc in GetRIL ?
* Aiuto, credo di aver perso il mio IMEI?

Se volete vi traduco le domande che vi interessano.
This is the FAQ section
I will constantly update it with frequently asked questions. If you miss anything send me a PM or post it in this thread!
These are the questions:
* What is a Baseband, what is a RIL?
* Which baseband is the best?
* How do I install a RIL?
* What RIL should I use? Should I install a matching RIL?
* Wait, what is SU660?
* Help, my baseband is shown as Unknown Baseband?
* How can I see what baseband I have currently installed?
* Why do I loose my RIL after flashing a ROM update?
* Why is my call-quality that bad? Why is the person on the other end constantly hearing a disturbing static noise?
* Why do I have a timeoffset after installing a new Baseband?
* What does "(V10b, Europe)" etc. in GetRIL mean?
* Help, I think I lost my IMEI?
What is a Baseband, what is a RIL?
A "rough" explanation: The baseband is the firmware for your hardware - the RIL is the driver for the ROM to communicate with the baseband. As each RIL is written for a specific baseband it is recommended that you use a matching BB/RIL combination.
Which baseband is the best?
The classic question. Unfortunately there is no good answer as this depends on your phones specific hardware, your carrier, your reception, your network, the universe...
You should focus on the newer Basebands (512, 420, 313, 1120, 725) or the initial 218 - the other ones have no confirmed advantages, but are listed for completeness.
The (closed) poll gives you a hint which Basebands are most used currently, but it doesn't include 521 which is used pretty often these days, too.
You have to try for yourself which one works best at your device! While testing keep an eye on in-call quality, wifi and 2g+3g connectivity. Don't forget to install a proper RIL (see the 4th question).
Why I can't be more precise? Well... you have to see that there are some people who have only one BB with which their device will work properly - and we weren't able to find a pattern, yet.
But as I still get many PMs about my recommendations here you go:
* As long as you don't have any problems you should stick to your baseband. Why bother changing if everything is working fine? I cannot confirm that Basebands influence battery life.
* Personally I would recommend the 725 BB from v10d with a matching RIL (see below), because it's considered stable and works for most people. 521 seems to be a good one, too.
* Especially if you have in-call problems (like me), for example a bad voice clarity or background noise, you should try one of the newer SU660 BBs (824, 1120, 420).
* I don't recommend SU660 Basebands if a P990 one is working for you! It might introduce problems, see this post for some examples. If you aren't happy with yours it's worth a try though - nothing can happen (if you backup).
How do I install a RIL?
Use the GetRIL app by sibbor or the LG RIL Version app by TrymHansen.
It's the easiest way, trust me. They will even create an entry in the custom_backup_list.txt file which will prevent the RIL from getting overwritten while updating your ROM.
If you want to install a RIL manually then download the "lge-ril.so" file and place it under "/system/lib"
What RIL should I use? Should I install a matching RIL?
Usually you should install a matching RIL. While other RILs might work for you, there's no reason to not use the optimized RIL for a specific baseband.
For LG Stock GB ROMs you need to install a RIL designed for GB and for CM and Froyo ROMs use a RIL designed for Froyo or the SU660.
For BB725 you need to choose a v10x RIL for Cyanogenmod-based ROMs and a v20x RIL for stock ROMs.
Attention: You cannot use a matching RIL while using a Cyanogenmod-ROM for 313, 327 and 512 BB because there doesn't exists a v10x RIL.
725 v10d, 420 and 218 RIL do work fine (but people have different experiences with in-call quality - check which one has the better quality for you).
Some more detailed information: (This information comes mainly from TrymHansen, thx!)
When LG updated the P990 to Gingerbread, they decided to update how the RIL works internally. aremcee called it something like different "service codes".
With CM7/CM9 or Froyo ROMs you need to use RILs designed for the P990 Froyo ROMs or for the SU660. P990 Froyo Roms have the version V10a-V10e and the SU660 has the versions V20f-V20j.
Stock Gingerbread ROMs MUST use a RIL designed for P990 GB. This means any version from v20a to v20q, except v21x which is Canadian Froyo and 20f-20j which are for the SU660.
Wait, what is SU660?
It's the korean version of the P990. It's similar but not identical to the P990, which means you shouldn't just use Software which is written for the SU660 on your P990. Same thing applies for P999 aka G2x, the american version.
Help, my baseband is shown as Unknown Baseband?
You have a wrong RIL installed. For LG Stock GB ROMs you need to install a RIL designed for GB and for CM and Froyo ROMs use a RIL designed for Froyo or the SU660.
Please refer to the question "What RIL should I use? Should I install a matching RIL?" for more information.
How can I see what baseband I have currently installed?
Go to settings - About phone - Baseband version. The last four digits are your baseband version
Why do I loose my RIL after flashing a ROM update?
Each CM ROM comes with RIL 218 which will overwrite your RIL. You can prevent that by creating a file called "custom_backup_list.txt" under "/system/etc/" and writing "/system/lib/lge-ril.so" into it.
Or use one of the RIL apps, they will do this for you!
Why is my call-quality that bad? Why is the person on the other end constantly hearing a disturbing static noise?
You should try 824, 1120 or 420 BB with matching RIL. You probably have a "Made in Korea" P990 (see the sticker under the battery) which sometimes needs a SU660 Baseband to have a good voice clarity on CM-ROMs.
See here for more information.
Why do I have a timeoffset after installing a new Baseband?
You're using automatic time and installed a SU660 baseband which expects NITZ timestamps instead of GMT ones.
There are two solutions:
1.) Deactivate automatic time in Settings - Date & Time and use ClockSync to sync your time.
2.) Use a Cyanogenmod-based ROM which supports NITZ timestamps, you usually see that in the OP of your ROMs.
Additonally you need to apply this fix by the great pastime1971.
(Note: For my ParanoidAndroid you don't need this nitz fix as it converts that automatically).
What does "(V10b, Europe)" etc. in GetRIL mean?
The Europe flag in getRIL doesn't tell you where this RIL is best used but where it's from. "(V10b, Europe)" means that the RIL got extracted from the Europe version of the V10b LG Stock ROM.
Btw: I don't think that your country is importand for the BB decision even if people tend to ask if a BB works in their country.
Help, I think I lost my IMEI?
This does happen to some phones occasionally, especially when flashing a SU660 Baseband.
Type *#06# into the dialer to check if your IMEI is shown as "0" or as another number than the IMEI on the sticker of your box.
If it does please refer to this post to get instructions on how to restore your IMEI.

Frango... Sai che rispetto il tuo impegno... Ma credo che questa discussione vada migliorata in quanto non tutti conoscono l'inglese... Il tuo fine perciò sarebbe vano, in fondo tutti noi bazichiamo xda, ma l'utente medio no ;)
Lunedì posso darti una mano a fare una lista in italiano... Così da far capire tutto a tutti... ;)
