[Q] No signal after going back to stock - LG Optimus 2x

I then reinsalled the stock rom named BIN_LGP990AT-00-V20g-234-XX-OCT-27-2011-0

Try some baseband with V20g in name, instead of V20s (different fw combatibility I suppose).
I am using these
LGP990AT-00-V20q-EUR-XX-JAN-24-2012+0_AP FW
LGP990AT-00-V20q-EUR-XX-JAN-24-2012+0_CP BB
BB is 1035.21_2011075
as it was the one the phone came with originally and works well with it. Beware that some FW/BB combination are not working well wor some phones. No pattern, it is individual.

check if your imei is not damaged... sometimes when flash a rom, it can to be damaged

Maybe a silly question but... Is that the model of the phone your trying to flash? I9000? Cuz here in PR the i9000 model is only for Claro not TMobile.. And they work on different bands.. But if u're sure that's the model, its fine..

i think i did flash i9000 maybe thats why? i cant find firmware for t mobile version :/
Its the vibrant firmware i need but i cant flash it it gives me FAIL on "modem.bin"
wow i think i just realized i didnt flash the Galaxy S 4G. Because of that when i try to update "4G" firmawre with odin it gives me modem.bin error all makes sence. Now only if i could find a firmware with pit and all the files to bring back 2.2.1 maybe and then go to 2.3.6 for Galaxy S 4G
Find your modem http://perka.zapto.org/ and flash.

[Q] Baseband updated but not the build number

Hi,
Great site BTW, some very cool things happening here.
Yes I'm a noob and figured that Q + A would be the best place to post a question!
so, I've trawled throguh the site looking for the best answer to my question and have not found one.
I found a post by someone with the same problem, but without an answer.
http:// forum.xda-developers.com/showpost.php?p=13522130&postcount=8
Basically, I downloaded Flashtool to update my baseband and build number.
My baseband is now 015, but my build is still 2.0.2.A.0.24.
I don't understand what I'm doing wrong??

The 2.0.2.A.0.24 is the build string of your ROM ...
Seems you're still running the genuine Sony Ericsson Android 2.0 update 2 ROM.
Last update ever released for the X8 was 2.1.1.C.0.0.
Baseband 015 just means that you updated the baseband (everything below the ROM ... kernel, loader, GSM/UMTS radio parts) to the latest version ever released by Sony Ericsson.
EDIT: In case you are not referring to the build string of the ROM but really to the build string of the baseband ...
Baseband 006 has a build string of 2.0.2.A.0.24 (came with ROM of the same build version)
Baseband 015 has a build string of 2.1.1.A.0.6 (came with ROM of the same build version)
So, if you are getting a build string version of 2.0.2.A.0.24 on the BASEBAND you are still on Baseband 006
Seems you're still running the genuine Sony Ericsson Android 2.0 update 2 ROM.

Yes, I'm still on genuine, but I have Android 2.1 Update 1.
Wanting to root, but I have read on here I need to update baseband and build first before doing so.
Wish I could get a screen shot to show you..
Looking under settings-->about phone I see
Baseband version is 015
Kernel version is 2.6.29
Build number 2.0.2.A.0.24
So do I have 2.1.1.A.0.6 if my Firmware version is 2.1 - update 1??
So do I have 2.1.1.A.0.6 if my Firmware version is 2.1 - update 1??

flash new baseband

hey
Im currently using apocalypse rom and its running pretty good on my ace.
I read a post saying that its better to install a different baseband (XXKPT)
im abit confused cause on my phone info now it says baseband: S5830NEKT2 and version 2.3.7
but the xxkpt is 2.3.6 ?
so shouldnt the 2.3.7 be a better baseband?
There is no need to change the baseband unless you are having any problems in the rom because of it.
The baseband change referred in the apocalypse thread is for changing the region of the firmware, not the version. You may use 2.3.7 for you region, but if there is any problem with the rom that a reflash or fresh Odin install is not solving, or due to app 2 sd scripts, then you should try a firmware from a different region, it has helped many people.
If the region(firmware's) you are going for has a different version then you have no choice but to downgrade.

thanks for the info. its much clearer now!
i did want to try a different baseband because of the app2sd bugs on the one i have.(with link2sd and amarullz)
It seems quite straightforward to flash another baseband with odin so might give it a go.
is there anyway to bkup the one i have now? or to find a download link? had a quick look on sammobile.com but didnt find the one i currently have(S5830NEKT2)
You can make a cwm backup,but i don't know if it backs up the baseband or not.
i mean if you restore this on another firmware then you will get this baseband back or not, i am not sure about that.

Yes, it does...
I'm not sure to completely understand.... If I choose the baseband of my country (XWKS9) and I flash on my cm7.2 stable official I'll change the firmware also no ?? If yes can you tell me how to change the baseband without change firmware ?
Thanks

Just flash the cwm zip for baseband or also known as modem...it will only change the baseband then...but i don't see much need of doing so because it's seldom that baseband causes problems...

It is quite rare but its there with the apocalypse rom, somehow the rom +sdext scripts have different compatibility with different basebands.

[Q] XMM6160 baseband

Hi there, i read few threads about baseband problems. i found this in older post (not my phone lol)
Details of my phone are
1) Model Number : LG P970
2) Android Version : 2.2.2
3) Baseband Version : XMM6160
4) Kernel Version : 2.6.32
5) Build Number : FRG83G
6) Software Version : LG-P970-V10d
Click to expand...
Click to collapse
so i guess this answer one of my question, that xmm6160 is froyo baseband the v10x or whatever. ??? is it correct ??
if it does than it would answer my second question, that i can flash any BB no matter if its from froyo, gb, ics and it should work with the phone. am i correct in this or not???
so now the question is, if my phone have xmm6160 BB and everything works fine except the auto time and date. should i flash v30 baseband? you think its worth it ?? is there a way for me to backup my current BB or i need togo the long way and extract it from the KDZ.
last question: if LG didnt release ICS in my region will the v30 BB work in my region, as far as i understand it may not work properly ?? am i correct ??
thanks

Try it... If that dont work, reflash your v10 baseband. That will take 5min
I suggest to download Clock Sync. Uncheck automatic time in option and use clock sync

thank you for your reply, i will try clock sync, about the flashing of BB im guessing that the post i found is indeed a v10 BB bcs the guy said that is phone is still in stock and unrooted, if i extract the v10e KDZ, is there a way to verify the BB version before i flash it??
BB version can be different for each country. A v10e from USA or v10e from EUR will have a different bb
If you want the good BB, take it from your country stock rom. Just need to flash the .fls file

am i correct that all custom roms do not have a bb ? if that is so, then my phone has the xmm6160 which is suppose to be from my old stock v10e
and if im correct about the above, than i should not even try to flah v30 bb, cause my country has only v10x version and not even v20 so ill stick to current BB i got.
and if im wrong can xmm6160 be a gingerbread BB?? that was flash when i had zeus 6.4 or marvel v9 cm7 or cici??
how can i verifay the .fls file that is xmm6161 file or maybe different ver. ??
thanks so much for clearing this stuff for me. :good:
Exactly, custom rom dont have BB. You are on which rom?
That depend... Im on IZS with the EUR baseband and automatic time work perfectly(im from canada). V30 bb fixed auto time problem. But im not sure if v30 bb will be good with your v10d rom. I can only say, try it
