Need Advice Please: GT-I9190 frimware update /no mobile data connection - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hello everyone
I've been battling with this issue for over a month now. I recently flashed CM12.1 / AICP 10.0 on my GTI9190 serrano3gxx and while they are beautiful ROMs, one problem arose. My mobile data doesn't seem to connect at all. WIFI, SMS and calls work without a hitch. I have tried all possible APN's for my carrier (Vodacom ZA) nothing worked. When I reverted back to my NAND backup of the stock ROM the mobile data was offline as well. Which makes no sense to me because it used to work fine in that configuration. This at least gave me the conclusion that the problem isn't ROM related, but then what?
Pretty much where I am now is I'm downloading an update for my firmware. I found a list on http://www.sammobile.com.
Original firmware: South Africa XFA I9190XXUBNA1 (Release date: 25-02-14 Version: 4.2.2)
Now downloading: South Africa XFE I9190XXUCOD2 (Release date: 01-07-15 Version 4.4.2)
Does this seem like the right path to take? I'm really struggling to find ANY sufficient information on the matter for my specific model s4 mini. Almost no information about firmware updates or anything on XDA. I'm not even sure of the risks from doing this firmware update. Will I still be able to run CM12.1 or AICP 10.0 etc? Will I be able to revert back to an older firmware version if this fails? (I'm leaning toward no)
All I want is for my mobile data to work again and this is the only sort of sensible option I've come across, however limited the information on it has been.
ANY help would be much appreciated. :good:

Update on this:
I first isolated the modem and tried flashing that (three times as recommended) Didn't work.
I then flashed the new firmware, which also didn't work. I'm now on new firmware and have tried different modems, nothing works.
Like what, is it actually possible to just "break" your modem? I'm starting to lose faith here.

[SOLVED. Seems like it was Vodacom denying me access somehow for whatever reason. Had to get a new SIM. Sigh. All that hassle.]

I9000zsjf7

Hi there,
I'm not sure if this would interest anyone, but I have an Asian bought Galaxy S and my baseband version is : I9000ZSJF7
I upgraded my phone via Samsung Kies sometime last week. I'm not sure what the original baseband was.
Just thought I would try and contribute, you never know who is interested in these sorts of things
ZSJF7 is Hongkong based ROM

Do you have the asian csc file I upgraded to a eu version. Would like to flash back
to the asian version. From what I gather csc deals with network settings and gps settings best optimized for each network. After updating to eu my gps has gotten worse than before although thats not saying much as it was not very good in the firstplace
It is already available from http://samsung-firmware.webs.com

[Q] Radio/Modem Files for Wave 8500

Hi there,
Apologies if this is the wrong section or if it has already been posted.
I recently acquired an 8500 from Overseas (Middle East region) which doesn't seem to hold a stable 2G or 3G signal here in Australia (both before and after the update - see below).
I am normally an Android guy, and with Android you have the ability to flash different radios/modems/basebands btu I cant seem to find this anywhere. Is the radio automatically upgraded when flashing a new firmware?
I just (literally hours ago) upgraded to KL6 but it seems the radio hasnt changed.
WHen I type in *#5239870*# into the phone this is what I got both before KL6 and after.
Pre flash to KL6
S8500+JP+JH1
Modem:
SHP: VPP R5 2.1.1
CSC: S8500OJPJG1
Post flash to KL6
S8500+XX+KL6
Modem:
SHP: VPP R5 2.1.1
CSC: S8500OXAKL6
Note in both cases, there is nothing next to Modem
Is there a repository of radio files that is out there (for the life of me, no amount of google or xda searches have found anything)?
Any Australian users out there care to share what modem they have?

That was for bada 1.2
Nothing available for 2.0 yet
Best Regards
Thanks, I am getting 3G but its just seems unstable.
Can I flash that same amss.bin from the argentinian 1.2 with my KL6 bada 2.0 firmware?
Frankenware 1.2.0
you can try but honestly i doubt that it will work
Best Regards
Right, MyLove90. I just went through the same thing with Bada 2.0 flashed on a Bell Mobility Canada S8500M that I am trying to use in Thailand.
Step 1 - Try amss.bin from DXKE1 firmware with Bada 2.0. - No boot up - freezes on flashing SIM image.
Step 2 - Try to flash DXKE1 complete firmware. This is a downgrade from Bada 2.0 to Bada 1.2. Also set Preconfiguration to THL (Thailand) from default KOR.
Now the phone boots up, but it it cannot be used with the GSM network. Why is this? GSM is a world phone, right? People travel all over the world with their GSM phones and just buy local SIMs while travelling don't they? I had no trouble at all with this when I first brought my T-Mobile G1 phone from the US here. I just popped in the same AIS SIM and it worked fine with no fiddling with the phone at all.
By the way, my Thai carrier is AIS, and setting preconfig to THL makes this a fully AIS phone. AIS menu options and Mobile AP settings, etc that were not there before now appear all over the phone menus.
When trying to dial, I get the no network service error. If I try to select network manually, or access the SIM for a contact phone number or to set a PIN lock, the message changes to "Emergency Calls Only".
So I'm starting to think that I have a defective phone with bad radio, but I figure, well, I can dial 911 with no harm because here emergency is 191. So I dial 911 and the phone dials and starts ringing. Oops! So I hang up so I won't get in trouble, but at least the phone works!
So what's wrong? I went to AIS and after playing with the menus and trying one of their SIMs, they blame the phone not being from Thailand, but as far as I can see, after the Thai firmware flash, this phone is the same as what Samsung shipped to AIS themselves. There are no SIM locks or any reason the phone shouldn't work.
Any ideas? Am I missing something?
can you please mention full info about your very first firmware maybe i can get it for you from Check fus or Slyfer ??
S8500M model is not available at all on Slyfer ...I just heard about it today
You can see...i am from Egypt and here we don't have branding or network lock and such stuff
So all what i can do right now is getting your old firmware for your so your phone work again
Best Regards
Wow! I never even thought about that being a solution!

You also have to pay upwards of €100 per download, not sure if the CSC is included for that price either. I know because I bought 2 firmwares several months ago.
sabaramo, it sounds to me like your phone is not a 8500T or a 8500M model. Thus unless you are with Telstra, using the Argentinan modem file wouldn't be recommended as you would be changing your broadband frequencies.
Who is your telco?
Let me have another try with SamMobile this time
Maybe our admin add support for Canadian Wave
Please don't pay for a firmware again

You are so right mylove90! This experience is starting to bring back memories. I've been using my G1, so this phone has been put aside since I got it, but now I'm remembering how hard it was to find the original ROM. KrazyKong is right. It is 120 euros to download from that site. But with your help and suggestion, I started additional searching.
First I found this service tech offering to share it for a fee because he bought it too. I remember finding him last time I looked for the FW:
http://tinyurl.com/83w3q8k
He's actually on the second page of that thread, and I saw him around other forums last time I searched that firmware too. Other than the pay services, he's the only private party that comes up on that firmware search.
Still, I decided to search the FW name again to see if it crops up anywhere else for download. Actually, after a lot of practice with these searches, I'm starting to learn that Google isn't too useful, and that searching file servers like Megaupload directly are more useful, and those all panned out negative, as I expected since that firmware was non-existent last year too.
But searching that ROM number did find a fresh post from someone with the exact same phone as me and the exact same problem. It's really timely because he just posted the problem 5 days ago and found the answer 3 days ago.
http://tinyurl.com/7x25ags
In a nutshell, he recommends the Brazilian firmware because it has the same bands as our Bell Canada S8500M phones. I gave a try first just to flash the amss.bin file over my Thai firmware, but no luck. I am thinking it is because the Thai firmware I installed is Bada 1.2 and the Brazilian is 1.0.
So next I tried to flash the Open Brazil he recommended (but didn't work on his phone) because I didn't want to try the branded one first. That was unsuccessful because it's not a full firmware and I got error messages in downloading. I'm guessing again it's because I'm trying to load Bada 1.0 over 1.2.
Still, before going to the branded (Vivo Brazil) firmware, I took another look at samobile.com/firmware and found 2 similar Brazil ROMs misfiled under North America. But more hopefully, I found another "U" series ROM: S8500L UHJL1 (Bada 1.0)
I was hopeful for this because my Bell Canada phone is similar: S8500M UGJF5
Because of the common "U" prefix, or the close UH/UG combination, I had hopes that this might be a correct firmware belonging to my Canadian hardware, but for the other Canadian Wave provider/carrier, Rogers.
While I was flashing, I noticed the file name protocols for firmware files and saw that the Brazil file had "Open Brazil" embedded in the file name, so I checked the corresponding file name in this ROM and found CI Entel PCS, which is a provider in Claro, Chile. This corresponds well with the other firmware for S8500L, VCKH1, for Claro, Argentina.
So anyway, after finishing the flash, my phone is working again thanks to your tips and suggestions to point the way.
Thinking about the theory behind this, I have to ask why the regular telephony GSM bands didn't work regardless of firmware, or why flashing different amss.bin files didn't correct the problem.
The only thing I can conclude is that these S8500M phones have a different modem to accomodate Bell Mobility Canada and need firmware to support the oddball hardware. Fortunately this same hardware is available in other countries as well. This procedure also changed my phone to an S8500B.
my head is going to explode
WTH all these brands for
Why it isn't just a normal phone ?!
But still i have curioustiy to get that damn firmware for free
Thanks for explaning...maybe others can use this
Best Regards
I won't be paying for another firmware no. But the branded firmware I was after could not be located any other way than by paying and going through www.anysvc.mobi

Yeah, I understand the feeling mylove90. It had my head spinning too. This has been a big learning experience for me too. Like you, I just imagined all the phones were the same, and that having the right firmware would make it work anywhere in the world.
I can only guess, but I'm thinking a lot of non-standard telecommunications equipment is out there with the carriers, and Samsung just tries to accomodate their needs for hardware variations so they can make the sales.
A consequence of all this is that I have lost Badadroid. I used Rebellos' Bada 2.0 fota to install Badadroid the first time and everything worked fine. Now I need to set it up with Bada 1.0. Of course, this firmware isn't on the supported list in the tutorial, but I tried a couple of fixes posted in the thread.
First I installed the bootloaders that are supposed to enable you to run the regular TUT fota on any firmware version. I don't remember off hand what post I got them from, but they installed fine and did not disrupt my phone at all.
Next I tried to install the fota for Bada 2.0, but it doesn't work, giving a fota erase error. I suppose again this is a consequence of trying to mix Bada 2.0 files with Bada 1.0.
So, since I supposedly have the boot files that work with the TUT fota on any firmware, I went ahead and flashed the regular TUT fota. It will not start Android. It goes straight to Bada.
So then I got Rebellos new universal boot fota that is also supposed to run any firmware here:
http://forum.xda-developers.com/showthread.php?t=1020444&page=34
http://code.google.com/p/badadroid/downloads/detail?name=S8500_bl_univ_boot_v2.3.zip
It does not work either, booting straight to Bada.
Any ideas? I hate to lose Android on this phone.
Also, if you find that Canadian firmware for free, let me know. I would like a copy in case I ever need to restore the phone to original.
You are trying with bada 1.0 !!
Fota won't work for sure because it is not supported at all
Also bada 2.0 Fota may have a different address
Universal fota may have or may not have your bootloader address it use
Flash XXJEE bootloader because i am sure it is supported
I think it will work as normal bootloader
S8500XXJEE bootloader : http://code.google.com/p/badadroid/downloads/detail?name=S8500XXJEE_BL.zip&can=4&q=
Also you may need to patch apps_compressed.bin to make it support fota
About patching apps
You can use mijona's app : http://forum.xda-developers.com/showpost.php?p=15159642&postcount=309
You have to use it through windows cmd....place it with apps file you want to patch...go to that path from cmd and write command as following
App_ena.exe <inputfile> <outputfile>
Example : App_ena.exe apps_compressed.bin patched_apps_compressed.bin
or read my post and try to do it yourself : http://forum.xda-developers.com/showpost.php?p=15151700&postcount=300
I think mijoma did a good job already

That's what I was thinking in my process of trial and error. I felt like the OS was protecting itself judging by the nature of the MultiLoarder error messages, so I wasn't worried about bricking the phone as I tried to see what the phone would and wouldn't tolerate.

Okay. I put those in. The phone accepted them and continued to boot just fine, but there is still no Android boot, so on to the next step:

Okay, so true! It's been a long time since I have edited files in hexadecimal, so that's nice. I don't mind hex editing, but I haven't poked around with Wave Remaker to get a feel of how to operate in it, so I appreciate mijona's file.
Navigating in cmd is a nice time to do work in C:\ !!!
So that was fun, but flashing patched_apps.compressed.bin made the phone stop booting. So I went on to another route.
Somehow I still had a tab for this thread open from my amss.bin research. These guys are struggling with the same issue in Bada 1.2:
http://forum.xda-developers.com/showthread.php?t=1313675&page=3
Particularly this post gave me a lead on a solution:
http://forum.xda-developers.com/showpost.php?p=20068355&postcount=26
I didn't follow their approach of mixing firmware files though.
Since the CSC file is also a "U" series ROM from Latin America, and in fact closely related to the CI Entel PCS from Claro, Chile firmware that I had already used to successfully get my phone working, I decided to use the entire firmware to reflash my phone with the indicated firmware: S8500LVCKH1
This firmware has no bootfiles, so I used the ones you gave me above. This flash was successful as far as the phone booting okay and working with my carrier. I was surprised to see all my setup options and changes still preserved after the flash. I expected to lose everything on a Full Download flash. I only lost the numbers I store in Contacts for the service menus. This firmware changes my phone to an S8500L. I lose the cute Bada animation for a cheesy Claro animation, and get a stupid message everytime reminding me that data charges can be expensive. If you know how to change the animation back and get rid of the message, it would be nice!
Since this is a Bada 1.2 firmware, I was hoping for this solution to get BadaDroid running again. Unfortunately there is no Android first boot with the power+menu+vol up command. It goes directly and immediately to Bada first.
I tried this both with the Rebellos' Universal Boot 2.3 fota
http://code.google.com/p/badadroid/downloads/detail?name=S8500_bl_univ_boot_v2.3.zip
And I also tried it with the TUT fota, but neither one will boot Android.
Any more ideas?
Of course, all this progress is possible because of your help. Thanks.
This time i had to know what i am dealing with so i downloaded that firmware
and as i thought Apps_compressed.bin needs to be patched
flash the patched file from an old multiloader let's say 5.62 so you won't get errors
If after flashing the file your phone didn't restart please don't panic
Just turn it off then on and it will be fine
Don't use fota made for bada 2.0 please....use the one from the tutorial
About Power On/Off animation
We got a great thread made by adfree in which he explains everything : http://forum.xda-developers.com/showthread.php?t=944620
An advice : Use latest Wave Remaker because it is so cool in this part
You can even make your very own animation
Believe it or not
bada hacking is more cool than the whole Android thing to me and more fun but needs someone who really try to do it
Best Regards
Okay! Thank You MyLove90! You have really made a happy day for me today!
Patching this binary did fix my Android boot, and I spent the rest of the afternoon re-installing all my Android apps.
I miss Bada 2.0, but it wasn't completely functional, so I actually have a better phone now that I have gone back to Bada 1.2.
Even though the Android port isn't complete, it is more fun than my T-Mobile G1 because I haven't upgraded Android yet. Now that I have the Wave working right, I'll go ahead and update the G1 too.
I found this post from mijoma as to possibly why the patch didn't fix my Bada 1.0 install:
"It's also problematic with loading patched version using new bootloaders."
http://forum.xda-developers.com/showpost.php?p=15206739&postcount=1240
Of course, I used the same bootloaders you gave me for both the 1.0 and 1.2 installs, but maybe it was an issue of 1.0 compatibility.
I appreciate your appraisal of Bada. Before I got the Wave, I read rave reviews of Bada, so I didn't mind owning a Bada phone. I just need some Android apps when I'm out, so this phone is working great for me as is. It will be nice if the port is properly finished, but I'm glad I have what they have done.
Thanks also for the animation thread. I'll look into it and Wave Remaker more.

I have a problem similar to PKJ2011. I have an unlocked Bell Canadian wave with firmware S8500MUGJF5. I am using it in Barbados with that firmware on a 2G GSM900 network. I flashed it with S8500XXKL6 Euro firmware and now it is not getting signal on the 2G GSM900 band. When I do a network search it picks up the 2G GSM1900 band but it has a circle with a slash in it. Is there anything I can do to get it working with the Euro bada 2.0 firmware on the 2G GSM900 band since this phone is a quadband phone?

Thanks for the tip. All three links go to usenet. They offer a free trial period, but you have to sign up for an account and give a payment method, so I'll pass for now. It's good to know the resource is there if needed.

You have to wait for Bada 2.0 to be released for one of the carriers that uses our same modem. This includes some carriers in Australia and South America like Brazil, Chile, and Argentina. So I had to downgrade to Bada 1.2 to keep my phone working. I used Claro in Argentina.

[Q] FIRMWARE UPDATE(which is which)

Hi Guys,
I want to update my current firmware version(2.3.6-DLC1)(Stock) to the latest stock(DXLM3) firmware for my country(Philippines)but i was hesitant which firware to download.
I visited samobile.com and i was confused on what to download on the site. there where 4 stock firmware with same baseband(below).
GT-I8150 Philippines (Smart) 2012 April Android 2.3.6 I8150DXLM3 I8150OLBLD1
GT-I8150 Philippines 2012 April Android 2.3.6 I8150DXLM3 I8150OLBLD1 - for some reason no indicated subscriber
GT-I8150 Philippines (Globe) 2012 April Android 2.3.6 I8150DXLM3 I8150OLBLD1 and
GT-I8150 Philippines (Sun) 2012 April Android 2.3.6 I8150DXLM3 I8150OLBLD1
FYI, im a smart subscriber, but i also have a globe and sun sim which i usually both use, depending on my needs(sun=call)(globe=call and sms my friends)(smart=net,txt and call=1 option).
I have read that there where problems with regards to signal,etc when you have not set the right firmware specific for your country or subscriber, would it be possible to explain what is the difference between on all 4 firmwares?and also which should i choose base on my needs..
thnx in advance^^..
I'm not really sure, but here's my guess:
The firmwares where the operator is indicated, they are "branded" firmware, containing perhaps apps that the operator requested Samsung to include in the phone. This usually go into phones offered by the operator with a service/contract bundle.
The firmware without operater is most likely an "unbranded" firmware, i.e., the firmware used by phones purchased without contract, from a 'neutral' reseller.
The problem with signal is due to incompatible baseband; the baseband is the piece of firmware that communicates with the BTS and/or WiFi Access Points. The Telecommunication Authority of a country may specify a certain behavior (out of several) regarding the communication standard with the BTS / WiFi AP (for example: WiFi Channel Selection, which 'variant' of GSM signaling used, which GSM signaling 'options' are legal, etc etc etc).
From the list of firmwares you gave, I can see that they are all using the exact same baseband: DXLM3. So, there should be no problem using any of them within your country. (Of course, you really should choose the 'unbranded' one to save you from having to deal with annoying operator-specific bloatware)

I see..thank you so much for clearing it out..this means that i dont have to reflash a whole firmware since they are using the exact baseband.
the main Reason i posted this, is beacuse im guessing this might be the cause of why my 3g signal is not appearing and i cannot use 3g services, im currently at CM-9(RC5) and 3g is not appering even if i am already registed on the service,already tried to reregister, on/off airplane mode, reset apn, even manually set it but still to no avail..

I see..thank you so much for clearing it out..this means that i dont have to reflash a whole firmware since they are using the exact baseband.

CM9 does not contain a baseband; perhaps your baseband needs to be upgrade.
@sigprof has extracted and repackaged a whole gaggle of baseband images to allow easy flashing using CWM: http://forum.xda-developers.com/showthread.php?p=36690782
Get one, then flash the baseband right after flashing CM9.

[Q] Problems With VPN upgrade 4.4.2 i9195

XDA Developers Hi friends, I have a problem, if I have the solution here in the'll have no other side, I have a mini s4 LTE i9195, which was Chile, with android 4.3, making the decision to upgrade to 4.4.2 , specifically the German firmware, so went up and change my baseband and kernel, no problem until there actually works fine, but when using droidvpn or other vpn will not let me, does not even root permissions.
try changing firmwares and returning to I had, but nothing was still the same, in fact I worked before in 4.3 normal, but now nothing.
When installing cyanogendmod I returned to work, but there have always had, and with different equipment problems with vpn, every 15 minutes off.
I hope some help here, of course thank you very much.
I am not sure if I understood you correctly, but you seem to have a VPN Problem.
With Android there are some troubles with VPN and certain versions. For me, using OpenVPN was just solved in the latest 4.4.3 version.
You might want to search for routing with VPN. That was were the error was sitting.

SM-j730F Oreo to Nougat downgrade

Hi guys I am new to this forum so if this thread is in the wrong section I apologize.
I have Samsung galaxy J7 2017 phone (SM-J730F). which I bought carrier free-unlocked from a seller in Croatia.
Unfortunately I was stupid enough to fall for the OTA update and installed Oreo on it, after that my phone's battery
life was cut in half and apps started hanging and crashing. I wan't to revert to Nougat, I have tried to flash
two official ROMS downloaded from updato and sammobile but it fails every time. Yes I have tried
multiple usb ports, cables and etc. Problem is I can't find the carrier free ROM for CROATIA on neither updato nor sammobile
and I downloaded south east europe rom which doesn't want to flash. By browsing through multiple pages
I found that the problem might be in the bootloader version, Oreo has higher bootloader version and doesn't
allow flashing a rom with lower bootloader version (which I havent checked). Please guys if someone could help
me with this, cause oreo is driving me crazy and basically making my device unusable. I'd appreciate it if someone could provide
links and tips or walkthroughs. Thanks in advance
PHONE INFORMATION:
MODEL NUMBER: SM-J730F
ANDROID VERSION: 8.1.0
BASEBAND VERSION: J730FXXU3BRI3
KNOX VERSION: 3.1
