Hi Guys , New to the forum but I have learned a lot in the last few weeks, from the excellent guides and information in the forum ,however there is a question that somehow no one seems to answer, I have a samsung galaxy s with the following firmware
PDA : I9000XWJM3
Phone : I9000XXJM2
CSC :I9000OXXJM2
The phone is about 2 months old, anyways I have done a few Custom rom Installs and flashed newer versions of android, and I find that every time I revert to a nandroid backup, of the orignal firmware , the baseband (I9000XXJM2) will never restore back i.e will always keep the baseband of the custom rom or the newer firmware, now the problem is that I cant find this stock firmware anywhere on the net, neither can I backup the orignal baseband. the versions are always either older or newer than my stock firmware... the phone had a dead pixel so sent it back to samsung and it came back flashed with my old original firmware. now to get to the point is there anyway to backup the baseband ? or can anyone point me in the right direction ? samfirmwares definitely doesn't have a copy of this original firmware. I sent the phone back to samsung with the incorrect baseband not even available in my country I may not be so lucky the next time something goes wrong so id like to keep a full stock version of the original firmware. any help will be cool
don't forget to back up the /efs folder. so that if your phone's /efs folder gets corrupt and you can't make calls, you can restore it easily.
by the way, your modem (baseband) can be found on samfirmware and it must be contained in I9000XXJM2 firmware.
the guy who flashed your firmware mixed 2 firmwares, that is the reason why you couldnt find it.
by the way, your modem (baseband) can be found on samfirmware and it must be contained in I9000XXJM2 firmware.
Can you find XXJM2 save the OP looking for the invisible firmware .
Looks like you have odd original, firmware .
Save baseband file downloaded from sam will include the baseband/modem file in the zip/tar file . You can just save that or extract the modem .Its possible to just flash the modem or swap modem in custom roms .
Can you open the Nandroid backup and see if modem is in that .

thanks , I have backed up the EFS folder already , but as I said I cant find that version of firmware, samfirmware does not have a XXJM2 firmware rather a XWJM2 firmware package the has a XXJM1 modem file in it

hi buddy
can u tell me or post a link on how to backup baseband?
Hello!
Many users have reported excessive battery drain and/or/due to intermittent loss of signal using the latest basebands.
I have been trying different basebands myself and found that baseband -36 gives the best combination in battery life and signal reception.
However, there are libraries in /system/lib that are related to baseband and, in my trials,
it seems that they made a difference in how the baseband was functioning in a different firmware than .368 (in which it initially shipped).
In other words, I've simply come to the conclusion that each baseband needs its appropriate libraries.
UPDATE for people asking which is the "best" baseband:
Bin4ry said:
@All asking for which baseband fits best:
Please please DON'T start flashing basebands without thinking about now.
Normally ALWAYS use the baseband which comes with the ROM! For example SE always has the corresponding baseband included. This baseband fits the android libs it comes with.
On custom Roms please read what the developer of the customRom telly you. If he/she has developed the Rom for specific baseband libs.
All other things like baseband patches are tested and developed by other developers which know what they are doing. So if you use such a patch ALWAYS read the manual and the requirements. Because it CAN happen that it is NOT possible to use a GB baseband on a ICS rom and vice versa. The is a little more than "just" libs and firmware. Also the java part framework/base/com/java/internal/telephony....
has to fit the baseband (SE is very special here).
So i hope now you all understand. Please please please leave the decision which baseband is best and which is working to the devs who know what they are doing!!!!!! Don't come here and tell "i tried baeband xxxxx now my phone randomly disconnects data/voice/..."
Thanks

And now, here are the patches flashable in CMW recovery:
DOWNLOAD THE PATCH for -36
(It will NOT change your baseband!!!
It will only flash baseband's -36 libraries in your system.)
DOWNLOAD THE PATCH for -64
(It will NOT change your baseband!!!
It will only flash baseband's -64 libraries in your system.)
INSTRUCTIONS: Of course you need to be on STOCK SE ROM, on baseband -36 or -64* and on any other firmware other than .368 and .062.
Place the patch zip in your sdcard, boot into CMW, flash it, reboot and enjoy!
Works for Arc and Arc S. Tried it on .042 and .058 ROMs.
Even better instructions, by DooMLoRD:
DooMLoRD said:
step 1:
flash baseband FTF via flashtool
step 2:
boot device and go into recovery
step 3:
while in recovery mount USB storage and connect device to PC
step 4:
copy the patch flashable (update.zip) to sdcard
step 5:
unmount sdcard via PC & also via recovery menu
step 6:
flash this patch (update.zip) via recovery
step 7:
reboot and enjoy!!
u can skip step 3 to 5 if u already have the patch update.zip on sdcard

* Here is baseband -36, flashable ftf for FlashTool.
DOWNLOAD baseband -36 (thanks to erwin929)
If this file doesn't work for you, kindly find baseband -36 elsewhere.
* Here is baseband -64, flashable ftf for FlashTool.
DOWNLOAD baseband -64
If this file doesn't work for you, kindly find baseband -64 elsewhere.
NOTE: Test the new libraries for at least 1 day before reporting,
in order to have more thorough proof of the improvement or the lack of it for that matter.
Simply booting after flashing the patch and seeing less signal bars doesn't mean anything by itself.
After running your phone for several hours on battery you can see the battery graph,
in the About Phone section, and check for signal strength, signal loss, etc.

Make sure you use the latest version of FlashTool.
When I am going to flash the TFT file, will I lose any data? I am on stock rom.42 and on baseband -56.

Yes, of course you are, because you just flashed the patch.
The ftf file is not an either/or situation, you want to change baseband, you flash it.
And if you are on baseband -36, you need to apply the patch.
any chance it will work on th eplay

Most probably yes, but I have no way to be sure.
You can make a backup and try it!
so we just have to flash the ftf using the link above?
is that all the steps needed?

I've been using the baseband -36 on my .42 firmware for at least a month without any issues!! (I just took the .368 firmware and flashed the baseband only using the flashtool which stated to supports that option) So what issues are expected if the libraries are missing?

Yea I been flashing different basebands since last week with flashtool trying out different combos but mostly with .42 build. Right now I'm on doomkernel with -58 baseband and battery is way better than it was with stock .42 -56 baseband and with no issues at all

When i select the .ftf in flashtool, it doesn't do anything, doesn't prepare it for flashing or anything???
Anyone else had this problem?
for a second i thought this was cobrato posting this (when i read the thread title )
great work Iris!
my baseband is 59 will notice the difference in battery if I change it?

Im confused by the tutorial. Basically im on 56 baseband with .42 firmware. So how do I flash this? Cause on the instructions it says I need to have 36 baseband already :S
---------- Post added at 10:40 AM ---------- Previous post was at 10:13 AM ----------
I dont think this works. I tried flashing the tft and all it does is says device connected and tft select then it doesnt say if its flashing it or anything. After waiting it just says device disconnected.
step 1:
flash baseband FTF via flashtool
step 2:
boot device and go into recovery
step 3:
while in recovery mount USB storage and connect device to PC
step 4:
copy the patch flashable (update.zip) to sdcard
step 5:
unmount sdcard via PC & also via recovery menu
step 6:
flash this patch (update.zip) via recovery
step 7:
reboot and enjoy!!
u can skip step 3 to 5 if u already have the patch update.zip on sdcard
same problem for me also, just sits there and does nothing with latest flashtool with this ftf baseband.

Did you get .ftf file? If you got .zip file like i did, renamed to
.ftf
CMW via flat when I finished and reboot and check the setting but it is still 56, I do not understand what I do wrong, sr my english is not good
Guys, let me make this even more clear to you (I'll at least try):
1. This thread is mainly about the PATCH.
The said patch is a .zip file flashable with CMW recovery.
It will NOT change your baseband.
It will flash baseband's -36 libraries in your system.
2. The ftf I posted is baseband -36.
It will change your baseband to -36 after you flash it with FlashTool.
It works for me.
If it doesn't work for you, find baseband -36 elsewhere.
3. If you feel that running baseband -36 on a different firmware libs gives you stable results, just ignore this thread altogether.
I am only trying to help, but I swear I'm starting to regret it.
Nice work mate.

Hi, I am new to xda and i'm also quite new to the flashing process. I have a captivate i896 and successfully flashed a rom on to my phone. However after doing so the phone is unable to connect to my mobile carrier. I have also tried to install a modem from the stickied thread how ever it gives me an error::
cwm 3.0.zip error
i'm going to try to flash the helly bean rom in hopes of getting that fixed.
also in the about phone section it says baseband is unknown... ive googled that and it said my IMEI is corrupted or something or other.
It sounds like your /efs folder is messed up. There's a thread in the Development section that goes through steps on how to restore you /efs and IMEI all on the phone.

I'm very lost right now, still cant seem to install any modems on and i checked in the EFS folder, there isn't anything
Please check first if your IMEI shows up in the about phone and that it is the same as the one on the inside of your device. For modems there are diffrent ones depending on what ROM you have flashed so give us that info please. Lastly if your IMEI is diffrent give this a try http://www.xda-developers.com/andro...s-ii-and-other-samsung-devices-in-nine-steps/, i have not used this my self but might be what you need

IMEI shows up as 'unknown'. I flashed the latest cm10 and used the modem KG3 under I9000.
Also, I'm in Toronto, so I'm running the i896 captivate.
i rooted and installed CWM by following the steps in this link http://forum.xda-developers.com/showthread.php?t=1350266
then after when i installed cm10 the IMEI dispapeared
sorry bump. but i think the problem is that i an unable to install the modem.. if anyone can please guide me to install a modem that would be very nice. ive tried to install it through CWM but it gives me a status 0 error everytime i try

If your IMEI shows unknown in the settings menu then it has nothing to do with whether the modem will flash or not. It means your efs folder was wiped. Now you could in fact be without a modem too but you need to fix the IMEI first.
Now with updating to CM10 theres a good chance it made a backup of this for you. Look on your internal SD card for a folder simply labeled backup. If so look in it and see what it has. Hopefully it will contain another folder labeled efs. If thats the case too then all you need to do is get something like root explorer or ghost commander and copy the contents of that folder into /efs in your system.
That will fix the IMEI issue.
As far as modems go you will only be able to flash these... http://soggycashew.weebly.com/cm7miui--ics-modems.html All the rest will give errors when you try to flash.
Question is in the title. Have at it!

Flashtool only seems to be able to flash FTF files. It won't flash a zip, or the uncompressed files.

Yes...
Just flash the .zip in recovery that you want to and if you want to keep a certain baseband or LTE then flash a stock ftf (with the baseband you want) in flashtool and exclude everything EXCEPT baseband. That will then just change the baseband to the one in the ftf and as long as that ftf has the baseband you want then you will be OK.
Baseband and RIL is part of a ROM.
If you want to preserve baseband and RIL from another ROM, change modem files in /system/etc/firmware and /system/lib/libril-qc-qmi-1.so in the ROM zip.

Can firmware files be switched out just that simple, or do I have to edit some kind of config/list of the files so that they are recognized by the flashing mechanism? Is there a way of finding out which stock firmware is absolutely necessary to stay for the device to work optimally?
Also, can the kernel of a locked bootloader phone be updated if the newer kernel is official and unmodified, which is to say it came by official manufacturer means? In my situation, my phone notified me that 9.1.A.1.140 was officially available for my phone which I could not successfully update because CWM Recovery on my phone was an issue for it. After flashing my phone with SEUS to reset it to factory default, it now claims that the version I already had before, 9.1.A.0.489 is now [somehow] the most recent. The only discrepancy is that it is a Rogers phone, but the only FTF I could find for the exact same model is from a Bell phone. They use the exact same hardware, and most likely same baseband (seems to work just fine), but ofcourse comes with a few different vendor apps.
Yes, you can just change those files (I changed whole firmware folder), flash newer radio and newer kernel with flashtool.
But RIL stays almost unchanged in JB versions (if you compare it in editor), so it is probably not necessary to change it.

When I try to flash the FTF over the ROM I get an error saying there is a SIN header mismatch.
The exact error:

Hello wisemen,
On a very related note, I would like to flash just my baseband in recovery from a zip (I've never used the flashtool). Is there a baseband repository for the Xperia T anywhere (LT30p model)? If there is, it seems to have evaded the search engines.
Background:
I'm doing this to fix the broken speakerphone and call echo in CM10.1.3.
Thanks in advance.

No. But if you download a ftf for your phone then you can exclude everything EXCEPT baseband to have the same effect (Ensure you UNTICK all the wipe options as well.)
When I want to flash a baseband using flashtool, I uncheck all the wipes and check all the "Excludes" except the baseband. But this method doesn't work, because when I check the device information, no change in the number of baseband.
I read that it is possible to do a FTF file that contains only the baseband files (after extracting the files from a Official Stock Rom). I want to know how to do this. So, if anyone knows how to do it, I would greatly appreciate that shares such information.
After that I would like to create a list of different baseband from different places and telcos.
Thanks!
PS Sorry my bad english
It will be very useful. thanks
