Hmm how i see, you tried many things for solve the problem. I think it's maybe a hardware problem and not a software problem.

It's still not solved yet, please help if anyone can!

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..

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

Im trying to get a V20G baseband but I cant find one. Anyone got a link? Ive tried other basebands in the link I said earlier and still no signal.
Please anyone, Im really not that good at this. I need a firmware and baseband download links that match each other but I cant find any.

[Q] Lost Phone Signal on Flashing ROM

Hi Guys,
Since I am new, I cannot post on the development groups. I was installing a ROM on my friend's S Advance. Whenever I flash a ROM, I am able to install everything properly but I have lost my mobile signal completely . I cannot make calls or send messages, the SIM works fine on other phones. What could be the problem here?
In Phone Status, it shows :
Network : Unknown
Signal strength : 0 dBm 99asu
Mobile Network Type : Unknown:0
Service Status : Radio Off
I have an Indian version of the phone, Baseband : i9070DDLK2
I tried looking for Radio files to Flash, but cannot seem to find it anywhere on XDA,
Please please help me out. Thank You so much for reading. Please let me know how to make it work.

I tried flashing this :
I9070DDULP8_ODDULP8_India_Android_4.1.2 Since the following were the only 2 available for India on the XDA links and the others I found, I thought I'd give it a try :
REGION: INU (India) | PDA: I9070DDLJ1 | CSC: I9070DDLJ1
DOWNLOAD
REGION: INU (India) | PDA: I9070DDLI1 | CSC: I9070DDLD4

Then I figured out it won't work for i9070DDLK2 so I'm trying to reflash to stock 2.3.6

No.. ddlk2 is 2.3.6 and ddulp8 is 4.1.2
First u need to flash ddlk2 which is 2.3.6 and then flash ddulp8 which is 4.1.2!

Okay. Thanks for clarifying. All these baseband versions on Samsung have me thoroughly confused.
I am pretty new to Samsung devices when it comes to rooting. Really appreciate you clarifying it.
Actually I had jumped from Firmware 2.3.6 to a custom ROM on 4.2.2 and then tried jumping back to Firmware 4.1.2 and hence the bootloop was occurring. (It's kind of making some sense now )
Thank you so much for clarifying, didn't read it clearly on blogs I guess, my bad. Firmware 2.3.6 is on download. I'll do a clean install of the firmware on ODIN and then try 4.1.2 and then custom ROMs. Thanks
Yes. And don't need to say 'Thanks', just HIT it!

[Q] How to update modem baseband when using custom ROM?

Hi,
I'm using Paranoid Android 4.5 Alpha 2 and I wonder how to update modem baseband to latest version without losing my actual configuration and ROM.
Is it possible?
If so, can you tell me how and what do I need.
Thanks by advance

why do you want to flash baseband?
Because I have issues with phone calls.
So I would like to take advantage of the latest baseband that would maybe fix those.

it might be an operator issue/rom bug.
dont fiddle with the baseband
It's not an operator problem.
So I suppose the problem is from my side (phone).
I used to have a Nexus 4 and ROM and baseband are 2 different things that you can flash independently.
Are you sure it's not the same with Xperia Z?
I already saw some topics with titles like Baseband Generic US something. But I did not find any Generic FR at the latest version.

You can download the french firmware and just flash the baseband from flashtool
Edit: Why dont you try EU firmware
I found out one topic for generic FR latest firmware and I used your trick flashing only the baseband.
Thanks!
Now I will see with the time if it's making my phone work better.

[Q] No network on new I9305

I just bought my second I9305 (first one was stolen) and it doesn’t connect to any network band. It is the same International model I had before that worked perfectly. I’m not sure if it has some country code limitation, but the frequencies and bands should be the right ones.
The phone is stock version. Baseband version XXUEMK1.
I’m not sure if I should flash to another Baseband. My cellular service provider works LTE at 1800 frequency and Band 3.
Any clues about what I should do?
Thanks

Hi,
Which is your stock firmware version JB 4.1.2 ? JB 4.3, or ?
Rooted or not ?
If you want to be sure your phone is OK, just reflash via ODIN your stock firmware from your country (and if you want from your carrier), it includes PDA, CSC and MODEM . Be sure your phone is an internationnal model i9305 and download your firmware HERE or HERE. I recommand this GUIDE from MaHo_66 xda member.

I've made some googling but I didn't found which modem version you have to use. I guess you have to find a latin america modem version but it has to be compatible with your current Android 4.3 build.
Did you previous stolen i9305 was running Android 4.3 as well ?
Do you know some ways to remember which versions you had on your previous phone ? Do you know someone else with the same phone ?

So try do a clean install by wiping all and flash latest build I9305XXUEML9 from italy (TIM) with Odin. It's Android 4.3 like you currently have.
You can grab it here for exemple : http://samsung-updates.com/details/24460/Galaxy_S_3_LTE/GT-I9305/TIM/I9305XXUEML9.html
Follow MaHo_66 guide.
Don't forget to backup.
I hope it will do the trick.
Hi,hbergold,why not flash the version firmware 4.4.4 Stock.Here you have two versions of 4.4.4:http://samsung-updates.com/device/?id=GT-I9305 So you would be clear if the problem is the modem.I use the version DBT Poland, I live in Spain and everything works great.Version 4.4.4 also includes again the possibility of entering service mode and choose the bands.You can flash it with Odin.Pasate por aqui:http://www.htcmania.com/showthread.php?t=920004

Gracias viktorak, but does this modem work with LTE band 3 (1800) ?
I can`t confirm, but with the the Service Mode you can force the band you will.Have you read the post I linked?Your partner, also from Venezuala wanted to force the band 5 -3G, and according to reported- it works.Then,using Service Mode you can force the band you will.
You need to first install the 4.4.4 Rom and then if it doesn`t work normally use Service mode.

@hbergold, about KNOX, you told me you have an Android 4.3 build, so if it's an official one, you already have a KNOX bootloader (the one from sammy Android 4.3).
About bootloaders:
- if you ever flash 4.3 or 4.4 via Odin or updated from OTA you have new Bootloader from android 4.3 or from 4.4.4.
- if you bought your device and you dont know what bootloader you have, turn off your phone,reboot to download mode (hold power + volume down +home buttons) and when is there Knox flag 0x1 you have new bootloader and you are warranty off. When Knox flag is there 0x0 you have also new bootloader, but you are still in warranty and when you'll flash any custom recovery or unofficial firmware via Odin, you'll have then Knox 0x1 and you will be warranty off - so it's on your deciding. When isn't in download mode any records about about Knox, you still have old bootloader (from android 4.1.2).
- since the new sammy Android 4.4.4 bootloader, now there is also a line in blue color saying ´´SECURE DOWNLOAD : ENABLED''
About @MaHo_66 's opinion, please read here : http://forum.xda-developers.com/showpost.php?p=56506775&postcount=12. I hope he will not find any problem of sharing his post
I also recommand to upgrade to an Android 4.4.4 build but it's your choice and it depends on what you want to do with your phone (install custom ROM or not = warranty stuffs / if you want to sell the phone later, ....). Also I think you will not be able to flash any older official build (Android 4.1.2 or 4.3) if you upgrade to 4.4.4 because of the bootloader. I recommand it mainly because there is no more this random ******* stuck mdm_hsic_pm0 wakelock issue appeared since sammy Android 4.3 and which was a big problem for battery life. And also because it's smoother and faster.
I hope for you that @viktorak service mode trick will work for you if you decide to upgrade to android 4.4.4 official.
