Flashing stock roms - Galaxy S II Q&A, Help & Troubleshooting

Can anyone point me to a collection of stock roms for flashing?
And how do we flash roms onto the phone?

http://www.samfirmware.com/
You'll need to sign up. There's also a guide on how to flash ROMs on that site.

Thanks!
When the 2.3.4 update is rolled out, is it essentially a new ROM flash? so the fw lettering and naming will change right?
Also, the XDA thread that lists all the stock fw, it is mentioned that the TAR files might contain all three subparts -
"If the package only contains one .tar archive then it will have everything, pda+phone+csc, in the one file."
Just wondering if I flash a Europe based version of a ROM, could I keep the Phone and CSC portion as per my region? Worried that flashing a Europe Phone and CSC portion might affect the signal and call quality~~

You can change modem /Phone and CSC
they will either work or not CSC most likely not to work as its country specific with a list of local networks but you can always set APN manually .

Flash modem.bin and Extract CSC from stock ? Please help

1) I have only a STOCK rom (one big tar file)
I want to extract the CSC package from this rom and flash it to another..
how can I do that?
2) also does modem.bin from the stock rom is the same as phone/baseband? can I flash it as "PHONE" in ODIN?
3) Does any modem works with every firmware? is't better to stay with the carrier modem? will it work withe another?
4) What about CSC? any advantage to use the carrier's csc? will it still work with another?
thank you.

Get direct CSC file from Dev section and flash that .
Stock Roms .and csc
http://forum.xda-developers.com/showthread.php?t=1075278
Or from phone copy out CSC file and CSC Files txt CSCVersion txt and SW_Configuration XML and just keep them to replace any stock files .
2) also does modem.bin from the stock rom is the same as phone/baseband? can I flash it as "PHONE" in ODIN?
Yes
3) Does any modem works with every firmware? is't better to stay with the modem the carrier gave me (with the original rom)? will it work withe another?
General rule is any modem with any firmware .
4) What about CSC? any advantage to use the carrier's csc? will it still work with another?
Advantage is that you know it has your network settings in it and thats all a CSC is a bunch of network settings etc .

1) I don't have my carrier CSC on the Dev section..
Is there any way to extract CSC from rom .bin files before flashing it?
please I have techinical knowlege and I know how to extract/mount etc..
2) I asked this because a lot of users said to me to flash it as PDA if the modem is in bin extension (and not tar).
you said to flash it as "Phone" so I trust you.
3) I know that the general rule is any modem with any firmware but still - can it be a condition in which the carrier modem (for me it's JHKG2) will work perfectly and an updated modem (KH3 for example) will make problems (like internet speed, calling quality etc..) ? or such condition will not happen?
this is why I'm asking if there is adavantage to use carrier modem and not the last modem - because I don't thingthe carrier put this version of the modem for no reason..
4) so CSC has only network settings - no other things?
there is a problem with my phone - after every power off and on, I need to register to my network operators again, so maybe the CSC operator will help in this case.
thank you.
Please help, if you know something please share..

No idea .

Modem is phone but it can be flashed via PDA .

Yes can happen so you change modem again.
this is why I'm asking if there is adavantage to use carrier modem and not the last modem - because I don't thingthe carrier put this version of the modem for no reason..
Carrier does not supply a modem they use the Samsung modem of choice .

CSC is the consumer software customisation and is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.

[Q] 2.3.5 Upgrade Questions

Dear Community,
I just joined the forums today but have done quite a bit of reading already, particularly about the upgrade to 2.3.5 i hope to carry out in the near future once i clear up just a few remaining points.
Just for the record: i have watched the introductory video prior to registration and am well informed concerning my duty to "search before asking". And while i have 'scoured' the forums for answers to every one of the questions i am about to ask, it could very well be that relevant information has eluded me by virtue of chance.
To a certain extent, these questions have in fact been answered to a certain extent already, however most have not been answered to a degree i consider sufficient before taking the plunge into firmware flashing. I therefore appreciate that to more experienced users my inquires might seem somewhat redundant. The most i can offer in return is to create an intelligible and clearly structured post that might serve to help others who find themselves in a situation similar to my own.
Here goes:
1. Frankenstein Firmwares: As the name would imply, these are custom ROM packages that are not official in the sense that they are not available through Samsung Kies (i.e. official channels), however they consist entirely of stock components. In other words, they are only considered custom because they are available in a particular configuration not officially sanctioned by Samsung and not available via their official channels.
Is this assessment correct?
2. Flashing via Odin vs. ClockWorkMod (CWM): To tell the truth, i am not sure to what extent these two are actually related. According to willk22's excellent FAQ CWM is " designed so that if the user messes up a ROM installation, they can recover their phone. CWM is a modified recovery installed into the recovery partition that allows advanced control over ROM recovery, installation and much more." According to this FAQ, it can also to "install a ROM contained inside a flashable .zip file."
Based on what i have been able to gather, ROM packages destined for flashing via ODIN cannot be flashed via CWM and vice versa. Just out of curiosity, when would i use CWM to install a ROM and when Odin? Is this left solely to the discretion of the developer? What are the major differences?
3. Frankenstein Firmwares vs. Carrier Specific vs. Country Specific: What i don't precisely understand in this regard is how the CSC (Consumer Software Customization) relates to the different ROM packages. For example:
Intratech, in his extremely helpful ROM thread offers a number of packages for download that are considered "multi-csc", meaning that by typing a certain key combination into my phone i can gain access to a 'hidden' menu which will allow to determine the CSC version. If i then select my carriers CSC, what would the exact difference be between a custom carrier firmware and the firmware with the specific carrier CSC selected?
4. Android 2.3.5 for SGS2: Assuming i want to install ('flash') the latest android firmware version containing Android 2.3.5 for my SGS2, which firmware would i be best advised to use? I assume that i would probably be most sensible to use Intratech's XWKI8 / XXKI3 / XXKI4 Frankenstein Firmwares. Assuming, however, that i live in Poland or the 'Nordic Countries' (for which an official 2.3.5 firmware already exists), would it then be more sensible to use the country specific firmware build?
5. GSM / 3G Issues: I read in a few individual posts that flashing a country specific firmware (e.g. Poland or Nordic Countries) could result in loss of 3G coverage or otherwise inhibit cellular service. Is there any truth to these rumors?
6. The Jig: I know what the USB Jig does (it is a physical piece of hardware used to reset the flash count of the SGS2 used in case the phone needs to be shipped to Samsung for maintenance) but i am not sure when exactly it needs to be used. For example, if i flash one of the firmware packages mentioned above (XWKI8 / XXKI3 / XXKI4), would i need to use a jig to reset my flash count to zero? Or does the use of a jig only matter when rooting a phone - rooting of course not being necessary for firmware flashing in this case - ?
Thats it for now. Thanks for bearing with me, and thanks in advance for reading my post.

Lengthy post there bud. I will answer to the best as far as I know as I am not all clued up either.
Q1 - yes is is correct because of the demand of different modems and csc packages.
Q2 - as far as I know you use odin to flash stock roms and CWM to flash custom roms. however CWM has a few nice features like wipe battery stats and NANDbackup.
(Hope you read about usb jig to reset your counter after flashing for warranty reasons)
Q3 - I am in South Africa where 2.3.3 is available via kies and I flashed both XXKI3 and XWKI8 so it is not country specific. I am not too sure if it applies if your device is carrier branded and you would like to keep it that way then you have to flash official firmware in carrier firmware thread or wait for kies.
The csc is for specific network settings such as texts, mms and phone calls. People sometimes have the problem of calls not coming thru or not being able to send texts. By flashing the csc for your region solves this problem.
The loss of coverage is related to the csc is what I think. Once you flash your csc it should be solved. Not too sure though. Ask the pro's to confirm but I have not had issues. But because I am on csc of my region

Yes; i might have been able to cut back on some things, but i also wanted this thread to be useful to people who find it through search so i decided it would be good to provide a bit of context.

That's the thing! There are CSC's for both regions and carriers. If i have the correct CSC of my region is that just as good as having the correct CSC of my carrier? I recently changed my CSC from my carrier specific to my region in order to get official updates faster and have not noticed any coverage issues whatsoever, so ive been wondering to what extent this makes any difference...

If you have the csc for your region, it will automatically be able to detect your carrier's settings. The csc are for regions, not carriers. If you flashed your region. Your good to go
lets try to give you so clear answer to your questions.
1. frankenstein versions are not custom roms and not official roms, they are different generic files mixed togather to allow for customizable for different regions by flashing different csc. they can be seen by kies depending on which csc is used.
custom roms cannot be seen by kies as the extensive customization to the files has removed or altered certain checks used by kies to determine if it is upgradable.
2. flashing via odin is using tar files and can be done external without the phone working as you can enter download mode by using the external hardware buttons.
CWM is a modified file used on a rooted phone which gives you more access to the file structure of your phone so you can install certain files like apks seperately. ODin will not allow individual apks to be installed by themselves.
CWM uses zip files if you want to flash custom roms are the developers can in future upgrades just replace certain files and post them within hours but tar files take a little longer to make.
cwm uses stored files on your internal sd card to maker changes but odin uses external files that have to be downloaded to your computer.
you can use internet on your phone to download the files then uses cwm to flash them as zip files usually have the installer as part of the file..
odin files have to be downloaded to your pc and a special installer packager called odin or heimdall if you are using a linux based machine to flash them.
3. basically the difference is that frankenstein versions as explained earlier are generic versions and not carrier specic roms which can be adjusted through the uses of modems and csc.
modems supplied with carrier branded roms will not work in other regions as their mdems (radios) for different regions and countries.
csc does the same as the modem but is geared to the data end of the phone.
4. if you want to stay as close t stock as possible use frankenstein versions with the csc for your region amd you can use odin to flash it.
if you want custom roms follow the developers instructions and use cwm to flash it.
5. Yes the rumors are true, different regions use different modens (radio)
Thanks for the replies - i believe i am slowly starting to get my head around firmware flashing.
Just one more question:
modems supplied with carrier branded roms will not work in other regions as their mdems (radios) for different regions and countries.

So this would mean, if i wanted to install Intratech's 2.3.5 Frnakenstein Firmware, that i would:
First: Flash the entire 2.3.5 standard package
Second: Flash one of the Multi-CSC packages that contains the necessary CSC for my region so that my network settings and mobile internet work properly.
Is this correct
What do i do about the modem/radio? I see that there is a special are where you can flash the the CSC in Odin, but there is not corresponding way to flash the modem. Will altering the CSC also change the necessary radio/modem settings?
Thanks again!

Yes, you are starting to understand the concept.
you can flash modems using phone section of odin.

OK..however the case with Intratech's packages seems to be that he only offers the CSC for download separately, whereas the 'Modem' is combined with the PDA and the CSC in one .TAR file, with the occasional exception for certain packages. I double checked the the Modem in the standard package is the correct one for my region anyway, so i wont even need to be flashing it fortunately.
Thanks again for the help!
modems can be downloaded separately if need or unzip the tar package into its seperate components depending on what you are trying to do.
You are fortunate that the rom suits your needs.

Yes, that is really quite lucky. I do have one question remaining however:
Will i need to reset my install counter with USB hardware jug after i upgrade my firmware using Intratech's packages?
Please note, i don't intend to root my phone - I just hope to upgrade the firmware.
Thanks again for all the great support!
Only if you plan on having some work done at a service centre otherwise do not worry about it. It has no effect on how your phone works.
Thanks!
I have successfully carried out the update and have made a small guide/FAQ detailing my experiences, which could be of use to other beginners who wish to flash their devices for the first time.

[Q] DO I need to change my CSC

Hi
Ok so I was with o2 on KF3, I've now flashed stock samsung firmware from here http://forum.xda-developers.com/showthread.php?t=1075278
I'm using the most up to date XEU one which is
XWKI4
Firmware info
PDA:XWKI4
PHONE: XXKI1
Date: 14/09/2011
Android 2.3.4
All o2 stuff has disapeared. I've read through the forums on changing the CSC and am confused.
Do I need to change it to XEU now to be able to update through kies? currently it comes up as 02U.
The firmware flash didn't reset my phone everything was as before. Which was nice, however I want the option to get the updates through kies or by flash.
Am i right in thinking I would have to change my CSC for this?
I see views but no replies - anyone no the answer or is it a smarties job?
Tried to change it anyway but phone wont let me dont even get a keyboard. Stuck it on clipboard selected all on 02U then pasted XEU ontop all i got was an error to say it had to be 3 characters any clues?

So after some more internet scouring and no help here it appears i need to flash a multi csc fw then change csc then reflash the one i have now......... Can anybody verify if this is correct or not?
Sent from my GT-I9100 using Tapatalk
To use kies again you will have to flash back to the original firmware,in your case carrier firmware,that came with you phone.If your firmware is not official or doesnt match your product code then kies will say that "this firmware cannot be updated" although your phone will still connect.The CSC firmware you have is a mono-csc package.If you try to change it or install a custom ROM on top it will say "CSC-UNKNOWN" because for custom ROMs and other changes to be done there needs to be at leats 3 CSCs in the firmware.The best thing you can do if you want to stay on this firmware is stay with XEU for your region or if you want flash the OXA multi CSC pack.It has varios CSCs to choose but i cant remember if it has XEU.You could always flash a custom ROM that has a multi CSC package built in to it like Omega ROM which im using but this of course means you cant use Kies.So the choice is yours.Stay with XEU if you want to keep to stock or OXA-multi CSC if you want to flash a custom ROM or back to your original carrier firmware to keep using Kies.
EDIT: Theres nothing Kies can do for you that XDA cant.Im in Spain on XXKI4 (Poland 2.3.5.) running Omega XT v3.0 ROM which has a EUR CSC for Europe built in to the ROM itself.So Ive got a Europe CSC thats works fantastic with a version of android that isnt even released in my country and a ROM thats fast and stable that gives me 2 days battery life with 3G on all day with moderate use.
thanks
Hi
Thanks for that, I guess I just wanted the best of both worlds, to be able to flash official roms from XDA as they come out for XEU but also have the ability to do the same through kies - ODIN was painless enough so as u say there's nothing kies can do for me that xda can't in that respect
Eureaka
So I factory re-set my phone from the recovery menu.......bang csc now reads xeu so it would seem to be that flashing the firmware as above won't sort csc on it's own unless a multi csc, but it doesn't matter which route u pick multi/single csc fw package you have to factory re-set to change it.
At least I know if I ever need to send the phone back to 02 I reflash, factory re-set and everything is as should be, although will the binary counter hint i've been flashing?

For the counter just buy a jig on ebay or maybe from a store if you can find one that sells them.Ebay always has them.It wipes the counter clean so Samsung dont know that yourve been playing around cos if the counter isnt at 0 then your warranty is void.Cost 2 bucks.The latest 2.3.5 official firmwares,also available here on XDA,have a new bootloader which is un-wipeable but there is an odin flashable old bootloader which allows you to flash the latest version and still wipe the counter.you can read about it here at the bottom of the Frankenstein section bellow XXKI3
http://forum.xda-developers.com/showthread.php?t=1075278
I also wanted the best of both worlds but at the end of the day all official kies firmwares you can find here from the link i just gave you anyway and flashing custom ROMs and back to stock and custom and stock again could also put your IMEI in danger of being corrupt.
EDIT: Heres a good IMEI backup method http://forum.xda-developers.com/showthread.php?t=1308546
Wasn't aware of that risk! Will have to get a jig as if phone busts it will have to go back via my insurance company and I'm sure they will check!
Also I've got Odin 4.42 now not odin 3 1.85 does anyone know how to use it to flash the GS2 as it's options are slightly different e.g one tarball support - dedicated option rather than just pointing the pda field at the single tar.
also the reset time has a value of 300 rather than just being a tick box. Other than that it's pretty much the same

About the new Odin im not sure.If your not sure then its probably a fail-safe bet to stick to v1.85,at least you know it works and messing around with things that your not sure about could end up with a bricked phone.Ive been flashing for donkeys and im happy with v1.85.If it aint broken....so ill stick with it.A jigs good to have just incase.If something happens you need to wipe the counter before sending it back.An IMEI backup is a MUST HAVE.Not really if your only flashing original firmwares but if you want to flash custom ROMs then YES its possible that something could go wrong.Happens not to often,to some people never,but if you dont have a backup then there is no way you can get your original IMEI back without sending it back to the service centre and that will cost you.No IMEI means on conection at all.No 3G,HSPDA or even signal.Not good at all
Cheers for the advice will stick to 1.85 it works lol yeah i stick to official fw interested to know how imei can get fried though

Stock Home .tar

I am in the Chicagoland area and just picked up a i9300 yesterday. Questions is, Does anyone know what stock firmware .tar i should grab? my firmware now out of the box is I9300XXALEF which i see @ SAMSUNGUPDATE.com but i don't see a US region and am not sure from there which country to dl.
Thanks!
used odin for flashing firmware stock samsung download here ; Odin (v3.07) is HERE ;http://samsung-updates.com/Odin307.zip
for download firmware samsung here ;http://www.sammobile.com
PDA refers to the build version of the software/firmware
Phone refers to the baseband/modem version
CSC is the consumer software customisation and is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.
CSC has nothing to do with what languages the firmware supports and it will not add keyboard language support either.
.PIT refers to the partition information table you only need it if you screw up your partition table or if the firmware specifically requires it because of a change in the partition table layout. It's very likely you may never have to use this.
If the package only contains one .tar archive then it will have everything, pda+phone+csc, in the one file.
If it has multiple .tar archive then:
The .tar with modem in the name is the phone/baseband bit of the package
.tar with csc/multi-csc in the name is the csc bit of the package
.tar with code/PDA in the name is the PDA part of the firmware package
If this is the case you will need to put these .tar archives in the specific areas of Odin to flash the update. Refer to the images below.
You do not need to root or unroot the device to update the firmware.
Please ensure that KIES is closed and not running in the system tray! Kies doesn't like Odin, it's like the big brother who's always jealous that his little brother is getting to flash all the phones so he starts to flash block.
Regarding change logs. Samsung thinks firmware should be like a box of chocolates, you never know what you’re gonna get and that all a big part of the surprise user experience program so they don't publish any change logs.
Thank you Sir! I can tell you the American phones backwards and forwards (been rooting for a few years now) but kinda lost on the international devices. So i can dl any region Home file and it will be good to Odin? Cause i'd like to grab the stock XXALEF it came with. Just didnt know if i would grab per se Italy for the Region if that would be ok.
you can flash any firmware for your galaxy, regardless of regional affiliation .. have fun

[Q] Rooted S2 - No signal even with a signal booster

hi guys,
I have a Samsung Galaxy S2 (i9100P), originally on orange, but since then I've moved onto T-Mobile. I have been having problems with low signal and many callers complaining that they cannot clearly hear and the sound is cutting out on both sides. T-Mobile have given me a signal booster and although the signal strength has massively improved, I still have poor call quality
Now I could be wrong here, but I think the signal issues have started since I flashed the original orange fw with NeatRom v5.6.
From searching on my pc, I've found my original orange brand fw, which was: I9100PXXLSS_I9100PBVLS2_I9100PORALS6_HOME.tar
Now I want to keep Neatrom, but I want to flash the modem and baseband which are showing as I9100XXMS4 on neatrom....I believe these could be the problem. Where can I get the correct versions that correspond to my mobile and network (EE) and how do I correctly flash these?
Thanks!
Come on guys, someone must be able to help me pls? :crying:
Just flash xxlss baseband (if it was ur original fw) in phone category in odin...
Thanks for helping me dr droid. I'll be honest mate... I don't have a clue what to do.
1. Do you have a link to a step by step guide to flash the modem fw and/or baseband? Could you show me?
2. Where do i get the correct baseband file for t-mobile network?

Download the firmware (the actual one which u said was present since the beginning)
Open the fw package with winrar
U will see a modem.bin file
Extract it to a known location

Thanks very much dr droid. The problem I have is that I've only got the original nandroid backup with the following files:-
boot.img
cache.img
data.img
nandroid.md5
system.img
I extracted these using yaffey, but there is no file called modem.bin. Could you please tell me where it is located?
If this is not possible, where can I download the original orange fw with the following details:-
(MODEL: GT-I9100P
ANDROID VERSION: 2.3.4
BASEBAND VERSION: I9100PBVKI2
KERNEL: [email protected] #2
BUILD NO: GINGERBREAD.BVKI3)
Nandroid backups don't include the modem. Download the entire rom from Samfirmware, extract the modem.bin from that, flash as previously instructed.
Thanks mistah.
I've just done that, but it seems that my mobile's fw does not exist on their site anymore:-
Model: GT-I9100P
Product Code: GT-I9100LKNORA
Hidswver: I9100PBVKI3/I9100PORAKI3/I9100PBVKI2/I9100PBVKI3
Filename: I9100PBVKI3_I9100PORAKI3_ORA.zip

Find the most recent firmware for your country/carrier, download it, extract the modem.bin from it, flash that. If you get no joy from that, try another modem from another rom for your country/carrier. Modems are cross-compatible between roms & don't need to be used with a rom that's the same Android version/whatever, E.G - you can use modems that came bundled with GB roms if you're currently running ICS or JB & vice versa, etc, etc. Basically you can use any modem for the I9100, though I wouldn't recommend using modems specified as being for the I9100T unless you've tried every other modem first as these are specifically 'tuned' for the I9100T/the networks of carriers which sold it.
If you find none of the modems bundled with stock roms released by your carrier work for you, you can either:-
A) Root your phone, and start flashing any CWM flashable modem you can get your hands on (there are dozens, obviously - one for each stock rom released by each carrier around the world, there will be several for each carrier at least). This will be easier than downloading several dozen roms & extracting the modem.bin for each if you do get to this stage
and/or
B) Service centre/local mobile repair shop, though I would be doing A & trying as many modems as I could find on here (you will find dozens with an XDA or Google search) before doing that given that involves parting company with money.

Thanks very much Mistah.
1. I've checked on Sammobile.com and there are new i9100P orange firmwares, but since I've now moved to t-mobile, can I still use these? Also does it matter if my phone is a "P" variant?
2. My phone is already rooted with NeatRom v5.6, so how do I:-
a. Backup the current modem incase I flash the wrong modem or mess up?
b. Flash the new modem?
OK...Some clear thinking required...
1) Basically you can use any modem for the I9100 (this includes the I9100P)
2) You can't back up a modem, or not easily at any rate. And you don't need to given how easy they are to flash. If you want to go back to a previous modem, simply re-flash it. If you don't have a copy of your current modem, you might want to find a copy of it somewhere before you go flashing something else (not sure why that would be important to you given your current modem is giving you no connectivity, but, anyways...).
3) CWM flashable modems are flashable in the same manner as any other mod/kernel/rom in CWM. You should already know how to flash stuff in CWM if you're running a custom rom, if you don't, you need to start doing some searching (and how did you get a custom rom on your phone if you didn't know how to flash with it ?).
Right. I've given you more than enough info & won't be posting further to this thread, this stuff is really very simple, and we have guides/tutorials (most of which are stickied near the top of the General section) you can read if you need further info, and everything you've asked can easily be found with a search.
Up to you now...
