Hi, I have a rooted xperia play R800i (unlocked bootloader and no simlocks) with stock rom 3.0.1.A.0.145 and 3G works fine (baseband 21-22). When I flash any other stock rom with higher baseband (tried 36, 56, 64), I lose 3G signal. I only get 2G connections. When I go into settings->Networks->Mobile Networks->Network Operators, I see only 2G operators. I have a Singtel connection (2100 mhz). On all firmwares I have tried, service menu says I have UMTS_1 UMTs_8.
The reason I want to go to new baseband (atleast 36) is to have custom roms and ICS on the phone. Giving up 3g is not really an option.
I have tried flashing old baseband after flashing custom roms (using flashtool, exclude system and kernel and then copying libs manually from old firmware for baseband) but I keep getting unknown baseband in settings->about phone. There is no voice or data signal if I do this.
Any suggestions to fix this problem will be very helpful.

Did you tried baseband from neo l's firmware?
I'm using it for a long time now, so i know it works. Maybe it will work for you too

Exlude all, leave just baseband in flashtool, no extra files needed.
(make backup, just in case)

Installed stock ICS with Lupus, installed new baseband (-87), but the same problem persists. Voice + 2G works fine, but 3G operators not detected. Any other basebands I can try please?

Have you tried just the baseband for .79? Its a world FTF.
Here is the link from my collection:
http://d-h.st/Mbi
I also have a baseband that I am using its .80 baseband, I have the FTF and the flashable files for it as well. I was getting edge where I live, in the mountains, after flashing .80 I went to HSPA+. Big difference in reception strength and stability for me.
Let us know how it goes.
---------- Post added at 04:48 PM ---------- Previous post was at 04:43 PM ----------
Here is the link for the FTF of the 80 baseband and the flashable zip of the 80 libs.
FTF:

Flashable Libs:

Just in case you want to test it out.
Thanks, will try it out tonight. Will post an update on the results.
Thanks.
Hi,
Tried both basebands and still the same problem. Flashed whole 79 ftf and no 3G, tried baseband 80 with libs, still only 2G. 3G works fine as soon as I install the old ftf. A strange pattern I have noticed that I would like to share. The only firmwares that have worked for me are the ones starting with 3.x.x.x, anything with 4.x.x gives the same problem. Here are the firmwares I could find and I tried them out and they work fine.
Xperia PLAY_3.0.1.A.0.145_UK
Xperia_Play_2.3.3_UK_Generic
These basebands havent worked for 3G
R800a_2.3.4_North America Generic.ftf
R800i_4.0.1.A.0.283_(1247-6212).ftf
R800i_4.0.2.A.0.42_Generic_UK.ftf
R800i_4.0.2.A.0.58_EnhancedV2.ftf
R800i_4.0.2.A.0.58_Generic Hong Kong Trade.ftf
R800i_4.0.2.A.0.62_(1253-4437).ftf
R800i_4.0.A.2.368_World.ftf
MT25i_4.1.B.0.631 INDONESIA_SONY MOBILE by wewenk.ftf
R800i_-80_Baseband_GSM.ftf
R800_4.0.2.A.0.79.ftf
Are there any 3.x.x firmwares available I haven't tried which have basebands which might work with ICS? That would solve my problem I am guessing.
Thanks.
See if there is dome ftf you didn't try at

Yes have tried installing DoomKernel ICS with stock ICS over 3.0.1.A.0.145, I get no network detection and get an Unknown Baseband in about phone. Also tried copying ouver the 7 lib files from the working rom into this setup but same error.
APN settings are the same across firmwares.

Do you have some friend who have newer rooted Xperia phone with ics or jb on it, and steal baseband libs from him

Hi guys, i have some questions about this procedure because all the procedures are made for LT18i version and my celphone is LT18a version (american).
I would like to know if there is any diferences about the procedure to install the CM10 on my cellphone, because of the diference about frequency from this two models.
I'm afraid realyse the procedures and my phone stop working.
I read on the forum that the main difference between the models is the frequency, and i woud like to know if there are any other differences, my cellphone operator works at 850Mhz / 2100Mhz - and the LT18i don't work at 850Mhz it works at 900Mhz / 2100Mhz.
Thx for help!

I also have the LT18a and I'm running CM9 and I've tried CM10 without any issues, I just reverted back to CM9 since CM10 had some stability issues.
Flashing a different kernel or ROM has not had any effect on my radio.

Backup what you can before rooting like sms,contacts,calendar,emails etc.
Unless you are rooted you can't backup apps, data.

Or you need to upgrade or downgrade the modem. Once I updated the baseband together with the modem, HDSPA also stopped working in CM9, so I had to revert back to the Baseband and Modem I used before and then I just updated the baseband without the modem.
There is a special thread about bug report in general section. Search the threat and you should find something about it.

So he has to travel into your country and go into your provider office to get HSDPA working? Ok, just kidding.
Well it depends on the operator and the modem file he has installed. I doubt his operator will change anything to make HSDPA working just for him while it´s working for all the other customers in this network. So he will have to down- or upgrade the modem itself to get it working again.
I also had this happen and lost HSDPA after upgrading the baseband together with the modem. Just 3G worked. No matter where I was. The solution was to downgrade the modem and to just upgrade the baseband. The same for many other users in our german forum who had this issue with specific operators. They all got it fixed by either upgrading or downgrading the modem because the operators will not change anything unless all their customers are involved.
it's true
Hi guys, got some problem here, Could someone be kindly to help solve this:
Hsdpa seem not quite working, i guess is a bug. Here the detail:
A) Galaxy Wonder (Indonesia)
a.1) gingger bread 2.3.6
a.2) DXLM3 baseband
a.3) HSDPA works like a charm - tottaly smooth
Then i flash to CM9 beta 1 with the following steps:

C) Download latest CWM
c.1) Install CWM via Odin = Success
D) Download CM9 beta 1 + Gapps.zip
E) Install CM9 beta 1 via CWM
e.1) Recovery mode CWM
e.1.1) Wipe cache
e.1.2) Wipe dalvik Cache
e.1.3) Install CM9 beta 1
e.1.4) Install Gapps.zip
e.1.5) Reboot = Success
F) Download DXLMB Baseband by THE-E
f.1) Install DXLMB via Odin = Success
G) Download JB-Adreno.lib
g.1) Install JB - Adreno.lib via CWM, Wipe Cache/Wipe Dalvik/Reboot = Success
H) Download AE-CM 4.3 Script
h.1) Install AE-CM 4.3 via CWM, Wipe Cache/Wipe Dalvik/Wipe Battere stat/Fix Permission = Success
I) Download forfolivo Kernel V3.2ghz.Stock
I.1) Install V3 kernel via CWM, Wipe Cache/Wipe Dalvik/Wipe battere/Fix Permission =Success
After doin' all things step Above, i think my CM9 already quite fine. Now been runing 5 batere cycle = 5day. But even with those above i still can't get hsdp conection. I already contact my provider and tell the issue they did do a full check and the result = nothing wrong with the network the problem is on your device!? Now after i hear those words i'm certain it's a problem from the ROM or setting which is haven't be applied. Any suggestion guys?

This Baseband does include the newer modem. Alfter flashing it HSDPA stopped working for me on CM9. To get it working again I had to flash a frimware with XXKL3 Baseband. Then I extracted just the DXLMB baseband from an other firmware and flashed it via Odin. This way I made sure the older modem that came with the XXKL3 Baseband in the other firmware was not overwritten by flashing THE-Es baseband.
After this HSDPA worked again.
But it´s not necessary to update the baseband. If an older baseband is working well for you, you can keep it as is. It´s just the modem that comes with the DXLMB baseband and is also included in THE-Es file is making some trouble in some provider networks where HSDPA stops working by using it.
It´s also possible the newer modem is not fully compatible with ICS/CM9 or like said somehow buggy and just working well while using a GB firmware. Can´t confirm this as I had the XXKL3 baseband installed first and flashed the DXLMB baseband after flashing and using CM9 for a while.
So all I can tell is why HSDPA stopped working for me in CM9. ( by flashing the above mentioned Baseband+Modem)
And how I fixed it.

If your baseband is of the DX family, I suggest you try DXKL1. Yes, it's old, but I *never* have any problem locking onto HSDPA with it. :thumbup:

Hallo all,
I have a silly question for anyone has time to lose: I have a LG-F180K, the OptimusG korean version. Why can I only use the rom F180K10H?
I tested several configuration and official roms, mixing my backupped baseband and roms, official OTA. but my phone works ONLY with F180K10H.
For example with the others official LG's rom mobile network doesn't work (I can't make calls!!), wifi works. Restoring the baseband (img) works mobile network but wifi not.
I tested the official upgrade F180K10H->F180K20C/G/I without success.
Ideas?

For now I'm on ICS. Unfortunately I didn't find the reason, but I think it is the baseband...
