XZ1 restoring camera/DRM keys - Sony Xperia XZ1 Questions & Answers

Hi all,
I recently picked up a used XZ1C with unlocked bootloader (thus nonfunctional camera) and started reading the XDA posts on the topic. Came across the thread on kernel and DRM bypass workaround which I highly appreciate. I wanted to ask few questions specific to my situation. I am not a newbie, had the Z3C and more recently Pixel 2 (much easier for flashing/modding) familiar with Magisk and other tools. No backup of anything (partitions or keys) in case that matters.
Looks like my device might be a USA model (nothing re: fingerprint G8441) and still runs the older firmware (built 47.1.A.12.179 with Android 8.0, see screenshot attached). I plan on using it on T-mobile USA and would like to enable fingerprint (if possible) and keep WiFi calling/VoLTE. Should I load the latest firmware and incorporate steps in this guide or do some other combination due to the existing firmware on the phone?
As far as I know, there is no TWRP recovery loaded, which I can easily do through command prompts. Is that my first step? What would I do next? If you can point me in the right direction, I will gladly read more and download/try things on my own. Thank you for any information anyone can provide.

Use a FTF where fingerprint is working e.g. Central Europe or Deutschland/Germany.
Find a suitable kernel (at least on same Android version level).
My XZ1 (no C) is running on

I think it is better to search an equivalent kernel for the Compact due to the screen drivers.

A very special custom ROM

Hi.
I'm not a programer or developer, but an Android enthusiast. I am looking for someone to help me (even payed help) to mode a stock firmware (Orange Hiro - Alcatel One Touch 6012 that run Android 4.2.2 ) in a very special and unusual way.
All I want is to block installing any other apk file on the phone, other than the app I will already install as system app into the modded firmware. I know that is possible since some carriers are already doing this (some US based carriers). There are a few ways you can do this, but I think that simply removing "Applications" part from firmware (or making it invisible or unresponsive) will be the easiest way. Sure, ROM stability is a must.
I hope that I have posted this thread on the right section.
Thank you.

I want to root my phone, but I don''t understand the guides

Hey!
I have an Xperia z2 D6503 with bulid number: 23.4.A.1.264
I tried one click root, but it did not work. I found this forum and tried to follow instructions to root my device. The problem is that i can't undersand anything! Flash? bootlock? why downgrades? PRF creator Method?
I have watched a ton of videos, read threds, but I can't understand it
My devices:
- Xperia z2 D6503 - bulid number: 23.4.A.1.264
- Lenovo yoga 3pro - windows 10
Is there a posibillity to get a really simplified method that works whidt my phone and pc? I will be ever gratefull!
You probably aren't reading carefully enough but anyways, lets start by one thing at a time, because you are asking way too many questions.
Flash means to install an android version onto your phone(this usually deletes everything).
Why downgrade? Because in order to root without unlocking your bootloader, you have to go back to an android version that can be rooted. You simply cannot root any version in order to do all the magic, you have to use a specific one.
Prf creator method means basically creating a prerooted android version so that you can actually use the latest android version while keeping root.
Feel free to ask questions BEFORE you actually do anything, so you don't have to fix something

Thanks for an answer! Sorry if I am to spesific or asks about to much. I compleatly understand that it was a lot of questions. Anyways, your answer helped a lot!
I read in one thread that windows 10 was not optimal for rooting my phone? Dose that mean i have to use another pc?
Dose bulid number matter? cause I did not find my bulid number anywhere.
Build number does matter (since it might make the difference between having to downgrade or not) and can be found on options -> phone information (if that is how it is called) or something similar.
Windows 10 is probably not the best choice but you might actually make it. Although I can't really tell you since the pc that I am using, has Windows XP installed... But if it is easy to find another computer (that has Windows 7 or something prior to that), it would most likely make the procedure easier for you.

[Q] Questions about modem update and a few other things

First, please forgive me if this is the wrong place, but this is the General Forum, and the forum software has changed a lot since when I was really active here as an active phone modder and active poster!
So like I said I've been away from the forums for a long time... trying to rereading a lot and trying to get back into MY PHONE.
I hate my modem sometimes because T-Mobile just sucks in some areas and is great in others [Greater Houston Texas Area, but mostly south side and towards the Galveston Bay].
I would like to know if the newer modems are interchangeable with the below config on my G900T?
And if there is any advantage to upgrading my modem? Wondering what modem I might be able to upgrade to with that below config and if there would be any advancements/pluses/gotmeinabadways/or other things I should be aware of if I did?
Also I'm wanting to upgrade to Marshmellow maybe, should I or should I just forget it? I will be reading more about the ROMs available. I've read a lot of posts about how buggy 5.1.x is. So I don't want to even go there...
Basic Phone info, Stock T-Mobile ROM [Damn bloatware] rooted awhile back with I think towelroot. I would really like to change to a slicker ROM that is debloated and maybe deoxed maybe. Will have to read hella lot more about that for sure..
Model SM-G900T Rooted
edit: Nova launcher
Android 5 not 5.1.x
BaseBand G900TUVU1D0B1
Kernel 3.4.0
TWRP 2.8.6.0 recovery installed
Broken Xposed :crying::crying::crying:
Can anyone recommend an app that will give modem info without having to decipher the baseband? or is there a very good break down of what each part of baseband means? I know go search!!! and I'm trying to reacquaint myself with the forums but the newer software is far different than I remember EKK! And search always hated me!! And even the different forum headers have changed due to time marching on and me being well Techtarded the last year or more due to things better left unsaid...
Have Xposed installed as noted above, but its been f00ked for a long time due to the ARM processor if I remember correctly and the Framework installer not being compatible..... Wish I could used the Xposed but........ I originally got into Xposed due to the Hex icons I actually paid for Xposed because I liked and used some of the modules made by smart people. Again but!!!

The most recent firmware and modem for the TMo S5 is version OL1,that came out in late December.
muniz_ri has been nice enough to put together a ROM that is the Stock ROM, already rooted, and ready to go:
http://forum.xda-developers.com/tmo...t/how-to-update-to-g900tof6-5-1-1-pc-t3141404
There are links there to the ROM, including the modem, or just the modem files themselves.

@daspazz the following website has decent basic info that seems to address the questions you ask: http://androidmodguide.blogspot.de/p/other.html
TLDR: yes modems are interchangeable
As for Marshmallow, I'm pretty sure for now, since there has been no official 6.0 update yet, you'll have to go with Cyanogenmod 13 (or one of the variants like Bliss 6.0 or Resurrection-Remix), they're in the unified development section (our phone's development codename is KLTE).
As for deciphering the baseband, look at the last three characters, let's assign them generic letters XYZ. X is the year (M being 2013, N being 2014, O being 2015, P being 2016, etc.), Y is the month (substitute the actual letter for its position in the alphabet), and Z is the revision number. So taking the most recent firmware (G900TUVS1FOL1) as an example: OL1: O means 2015, L means December, and 1 means 1st revision. Another example, build number G900TUVU1ANE6: NE6: N means 2014, E means May, and 6 means 6th revision.
It seems to me there's been some consensus that the most recent modem (which rlichtefeld linked to in the post above mine) is the best
Much Thanks!!!!
@rlichtefeld and @thisisapoorusernamechoice
I really appreciate the information gentlemen!!!! I've been reading through the info you both provided.
I did flashed my modem (only) to the newest one, G900T_OG6_Stock_Modem.tar. Ended up having to flash back to the modem for 5.0, G900TUVU1DOB1-MODEM.tar, because I literally could not hear anyone when I made or received calls.....
Also had to used Odin v3.09, because v3.10.6 wouldn't recognize my phone. Strange that!!
This ADB installer was very helpful!! It fixed problems I was having on the PC I was using to flash my phone. Much thanks to @Snoop05 for the ADB installer for the PC. It keeps you from having to install the full SDK for Android.
Thread moved to proper forum.

Oreo the 8th: Is it possible for g965U?

Hello all! I've got myself a dandy Galaxy 9 plus from America that cannot be rooted (sm-g965U), I'm told it is impossible to root this phone. I am also told something referred to as a bootstrap cannot be loaded except the 'stock' one that loaded the last cycle. So, my question to the experts is what, short of a new phone (currently researching older models), is needed to achieve either/or 1. Custom ROM? 2. Rollback Android? I would like certain features unavailable in 9 and 10 to be restored. And, I am told this is not possible as long as 9/10 are running the show.
Lastly, my apologies, I wanted to get some expert advice from this site. I suspect that much like in the name Boy Scouts, you know you should probably be a boy, I suspect I should also be a developer to be here. I'm not. (in case you were on the fence (wondering)). Cheers! Weeee!

Refurbished and guess what, messed up firmware

Hello,
I recently acquired a refurbished S9+ and as many other people, I realise now that someone must have been messing around with the internal software. This is my secondary phone so it's no big deal but I would like to understand what was done on it nevertheless, and maybe turning it back to a cleaner state, if possible, and if it has not too many drawbacks.
-apparently, Samsung Pay is not working. It hangs indefinitely on the screen where you must choose the type of security.
-when looking into the Play Store settings, the device is not certified
-WiFi calls apparently are unavailable
-OTA update is not working (nothing happens when I try to check for an update manually. What's more, no information about the last update is available. By the way, the phone software is outdated. (last Android security fix is dated from Feb 2019)
From what I read, it looks like the CSC was modified, right ? Would it be a good idea to change it back to original ? (I may need some guidance about that but we are not there yet) Would such a procedure restore, for instance, the OTA update feature ?
(see pictures attached - there is what is written on the phone's back cover too, if it can help)
Thank you very much in advance. Please tell me if you need some other specific screenshots.
PS : I also bought a Note 10+ from the same refurbisher and it ended up being a Korean model. But the firmware seems clean. I know Samsung Pay won't work in France, WiFi calls either, and I will be stuck in "LTE" 4G instead of 4G+ but at least OTA updating is functionnal (I got an update a few days ago) and honestly ? That's fine with me for the price.
Anyone ?
From what I've read researching on similar issues, the previous owner who messed around with the internal software must've flashed custom firmware on your S9+, and probably tripped Knox (and is why your Samsung Pay app won't work). According to some developers on here, you're able to hide the fact that you've rooted the phone, but I don't think you can un-trip Knox once it's been done.
Prior to your post, I didn't know a single thing about CSC and I'm not sure how it's really relevant when flashing a mobile device (unless it's carrier-related), but I think all that's required when flashing a device is the model number. Luckily, I stumbled upon a thread that is actually your exact, same model! Do what you please with it, and I hope I helped — I'm not a professional, nor am I really knowledgeable about all of this stuff, but I'm trying.
This is the thread I was talking about:
Official Stock Firmware Thread (11 August 2022) - Galaxy S9+ (SM-G965F)
UPDATE (7 APRIL 2022): Samsung has officially declared the Galaxy S9 and S9+ EOL. They will no longer be supported, and FVB4 will most probably be the final build for this device. Latest stable firmware: G965FXXUHFVG4 / G965FOXMHFVB4 /...

Oh thank you for the finding, I'll have a look !

You're welcome! Was it what you were searching for?
Not sure, but I hope it will help me understand the firmware/CSC stuff better
Alright so apparently this phone actually is a SM-965N, judging by what is displayed when booting into download mode.
Unfortunately I only saw this after starting a flashing attempt with Odin and now it's stuck at "system.img" so... I'm gonna let it run a few more hours but...
It's most likely bricked at this point, isn't it ? (edit : interestingly, after I forced-closed Odin and reboot the phone, it was not)
If you ask me I find this kind of "refurbishing" a little bit sketchy to say the least.
