Hello.
From my post number you can understand that i am pretty new to the android world. So from my short understanding,
Kernel=The core of the OS
Firmware=The entire OS including the core .
Correct me on the above if am wrong.
Now lets get on topic. I want to root and then bring my phone to the factory default kernel or firmware if that makes a difference.
Looking at my phone status and on topics like :
http://forum.xda-developers.com/showthread.php?t=1075278 and
http://forum.xda-developers.com/showthread.php?t=1101671
i see a lot of numbers that i dont understand.
First of all lets talk about my phone.
Baseband Version: I9100XXKI1
Kernel Version: 2.6.35.7.19100XWKI4-CL575468
Build Number: Gingerbread.XWKI4
1) The KI4 specifies the firmware version ? If yes why in the baseband i have KI1 while one the build number KI4 ? (i had KE7 before upgrading with KIES)
2) If i would like to download the original firmware from the thread i posted above i should go for the following as described below ? Even here, The Phone says XXKI1 while PDA XWKI4 . On which should i be interested and what is each of them .
XWKI4
Firmware info
PDA:XWKI4
PHONE: XXKI1
Date: 14/09/2011
Android 2.3.4
3) Even on the XWKI4 on the above thread, there are several links, OXX MultiCSC(AUT, COS, ...), DBT (Germany), XEU (UK) , XWKI4 Stock Kernel etc. My phone was imported from Germany, does it really matter what download link i chose ? What is again the difference in them.
4) Now about kernels. For an insecure kernel i should go for the GT-I9100_XWKI4_insecure ?
5) As last , to restore back to the factory default firmware (or kernel), i need to download the original kernel from the above thread i posted which would be ( GT-I9100_XWKI4_original) , or i can simply apply the firmware which would add also the firmware and would replace it without any problem ?
Thank you very much in advance.
no one knows the answer of any of the 4-5 points ?

Because you can see the baseband (modem) as an own package in the rom.
Sometimes the rom gets updated and the modem doesn't thats why the numbers are different.
You can also flash just another modem and keep the rest of the rom.

Looks good, just write down what kernel/modem/rom you have atm and get one with the same specs among the the original firmwares.

If you flash the original firmware it will contain the original kernel.
Hello,
I have a S6 Edge (Vodafone Germany) and flashed the UniKernel v8-0002 COH9 and kept the stock firmware, the build number is G925FXXU2QOH8.
The phone doesn't recognize my SIM card. After some googling I have found out, that it could be related to the missing baseband version.
I have found out that the newest firmware uses G925FXXU2COH2 modem. I have downloaded and flashed it, but it doesn't change anything.
The baseband version is still unknown.
What did I miss?
QOH8 and COH2 are quite the same firmware. The only difference is that the QOH( is for branded Devices and COH" for unlocked devices without any branding but in Germany there is no such thing as branding. You most likely have an international variant.
Maybe you could try to flash the whole firmware, not only the modem.
Thanks for your fast reply. I found out that my efs partition is corrupted.
My Samsung Galaxy S7 has the Vodaphone Baseband version G930FXXU1DQIL Its offering
to upgrade my firmware to a new version G930FXXU2DRB6
Is there anything stopping me putting a non carrier related Software on the
handset. I was considering installing a BTU version , PDA G930FXXS1DQLC. What is the difference from one version to
another? Is there much likelyhood in bricking the handset by changing the Firmware
So long as you use G930F firmware, you can flash any version and it should be fine. Just make sure you flash all 4 files.
Carrier specific firmware is what lets carrier features like VoLTE to work, but you can flash the BTU version, then flash just your carriers CSC and carrier features will work.
I've spent hours researching and digging up anything I could about what my situation is actually about and the different ways everything could've been done. This, and 1 other option are pretty much all I got left to cross off the list...
So, I already have the Phone INFO ★SAM★ app, I jotted down what it's stating the current firmware is and then I decided to check with the Firmware Browser and that's where I'm confused - There's 5 versions listed, none of which are the one that's on the phone.
Browser has as the latest firmware:
'DUDA'
2021-05-16

Latest firmware listed on my phone:
'DUE2'
2021-05-14

Am I wrong? Or is something up?
Basically the four letter/numbers you quoted ( DUDA and DUE2 ) is part of the firmware file name that tells you OS upgrades, year, month and revision number. The higher the letter/number the later the release. ie: DUE2 is the latest release.
Looking at your model number ( SM-G981V ) i can see two company/carriers that produce firmware for this device.
USA (Verizon) (VZW)
Comcast (CCT)
The USA(verzion) latest version is G981VSQU2DUDA while Comcast is G981VSQS2DUE2. Not all Companies will release firmware updates at the same time.
In regards to the Phone INFO ★SAM★ app i would say that it's checking for the latest version available for your model number but not carrier pacific ones.
Edit: The latest firmware for S20 5G UW (Model SMG981VZAV)(verszion) is G981VSQS2DUE2.
Looking at website like Sammobile may not be up to date with the current releases.

So even though my CSC is VZW, my phone is still updating to CCT firmware? I thought I was only supposed to have the versions specific to the CSC.

If your csc is verizon (vzw) and have a verizon sim card then your updates will be verizon. Generally all firmware will have the same file name through all carriers. Where i live my firmware name falls under OXM, which is a multi CSC format, where it has a range of csc for different countries/carriers.
As i said looking up firmware on website like sammobile or updato may not have the current releases yet. It should be noted that these website are the full version firmware of your phone and requires a PC and odin to install. Updating through your phone using software update does not install the full firmware just security updates ,bootloader version and major OS updates.
If you what to learn more (about csc) there are plenty of websites out there that can explain it better than me. It can be a bit more involved than saying i am on verizon (vzw).
Hello all,
I purchased a Galaxy A52 4G dual-sim model, and am (mostly) very happy with it. I bought it specifically for two reasons: because of the dual sim support, and the fact that there was a LineageOS rom available here at XDA. So, I promptly unlocked the bootloader and flashed TWRP and LineageOS 19.0 (big thanks to Simon1511 for his work on that!).
Everything is working great except for the second sim slot, which ranges from almost-functional (everything except voice calls work, no audio at all in call) to completely non-functional (cannot even connect to the tower), depending on which of my SIMs I put in it. The other slot is fully functional with either sim.
I noticed under Settings->About Phone that the phone reports it's model as SM-A525F, but the baseband version shows as A525MUBU4BVC2. According to the info at sammobile.com, that version is intended for an SM-525M, which this phone says it is not. I have no idea how that happened, and I wish I had done some testing with the phone when I first got it, before blowing away the stock rom. Ah well.
Hoping that my sim slot problems are the result of the wrong baseband firmware being installed, I downloaded the latest version for the SM-525F from sammobile (A525FXXS4BVD1), extracted the modem.bin and NON-HLOS.bin files, and tried flashing them to the device using Heimdall v2.0.1 (Linux user here, so Odin isn't an option and the 'official' Heimdall v1.4.2 threw various libUSB errors. v2.0.1 is an unofficial fork that worked, used it to load TWRP without problems.).
It uploaded, but the download mode screen displayed SECURE CHECK FAILED, and after rebooting the version listed under settings had not changed. Everything still works as well as it ever did, which is nice. Knowing that a mistake in this area could potentially brick the phone, I decided to create an XDA account and post here looking for some advice before making further attempts.
As I was putting this post together, it occurred to me to check the invoice. I bought it through Amazon, and it was listed as an A525M on the invoice, for what that's worth. And, the fine print on the back of the phone itself reads SM-A525M/DS. So perhaps it is an SM-A525M and the baseband version is correct, with the settings showing model: SM-A525F being the error. That would explain why the baseband firmware wouldn't flash, it knows it's not the correct bin file for the phone.
I suppose there is also the possibility that it's simply a hardware problem, and the second sim slot has something physically wrong with it.
Can anyone point me in the right direction?
Hi,
I'm certainly in no capacity to guide you, but I just brought the phone myself and have been lurking this forum to harvest a few guidelines. Regarding LineageOS, I saw there might be some problem with Dual Sim there :
[ROM][12.1][ENCRYPTION][EOL] LineageOS 19.1 for A52 4G and A72
LineageOS is a free, community built, aftermarket firmware distribution of Android 12.1/12L, which is designed to increase performance and reliability over stock Android for your device. LineageOS is based on the Android Open Source Project with...
forum.xda-developers.com
It could be you have the same issue as the guy and this is not related to your baseband firmware?
If I may ask, as a fellow Linux user myself, would you mind describing the guidelines to use download a working version of Heimdall and use it to flash e.g. TWRP on the phone? That would be much appreciated.
Flash the proper firmware for your device using odin. Then try installing lineage again.
@Flyos: I haven't seen or used any options for turning off SIM slots, so hopefully that isn't part of the problem. The source for the copy of Heimdall I used is available at https://git.sr.ht/~grimler/Heimdall/ . You'll have to compile it yourself.
@Ryzen5950XT: Thanks, but that's not terribly useful advice, given that part of the problem is that the device is giving me conflicting information regarding it's model number.
I'm still going to take it, though. I'll assume it actually is an SM-A525M and go from there. And I'll use Heimdall. It's served me well with every other samsung phone I've used, and Odin simply isn't an option without Windows, which I don't have and am not interested in getting.

There should be a sticker on the box the phone came in that tells you which variant it is.
...yes, and I touched on that, in the original post. The phone is physically stamped SM-A525M/DS, the Settings->About Phone page says SM-A525F, and the baseband version indicates SM-A525M again. Conflicting information.
Which is why, two-to-one, I'm assuming SM-A525M is correct, and will follow your advice and reflash the stock firmware, downloaded from sammobile.com.

Ok, did a bit more testing, pretty sure this is a problem with the LineageOS rom.
Re-flashed the latest stock firmware for an SM-A525M from sammobile.com (used the brazil firmware), and Settings->About Phone now reports the model as SM-A525M/DS, which is correct. Baseband firmware version did not change, nor did I expect it to.
Tested each sim individually in each slot, then both slots together, then swapped sims between slots. Audio worked in every voice call, regardless of which sim was used for the call or which sim was where.
Then I re-flashed LineageOS as per the instructions.
Starting with the VBMeta_Disabled image, then a recovery image (Used the LineageOS recovery from that thread this time, used TWRP from the TWRP website on the previous attempt), then LineageOS, MindTheGApps, and Magisk.
After re-booting Lineage, the phone once again reports it's model as SM-A525F under Settings->About Phone, and neither sim has working in-call audio when in slot 2, regardless of whether the other slot has a sim in it.
I'll add a post to the thread linked above to report the problem, and crosslink to this thread for reference.
For the moment, I've put the sim cards back in the phones I pulled them from and shelved this A52. I'll try again when a new release is available, and see what happens.
Thank you Flyos and Ryzen5950 for your assistance!
