Hi all,
I'm considering to get a Z5C, but I need VoLTE working. I know that VoLTE is working with the stock ROM, but how about Lineage OS or other custom ROMs? Does anyone have hands-on experience with that? Any suggestions much appreciated!
Cheers,
r.
VoLTE is definitely not working on any LineageOS ROM, no matter what version you are using.
Ok, thanks for this info. Here's two more questions:
1. You wrote "LineageOS" - do you know of any other Custom ROM where VoLTE is working?
2. How about VoWLAN aka Wifi Calling: Will it work with custom ROMs?
Thanks.
r.
1. No. My guessing is, that some IMS related stuff is missing. We (unofficial LineageOS devs) have tried it, but we failed. The normal telephony function has been compromised.
2. I don't think so (see above).
I'm sorry.
Ok - thanks for your efforts anyway!
VoLTE works mostly only with T-mobile firmware.... but you have to flash this firmware... stock z5c dont support this.... if you flash it "with your country local operator firmware"..... will VoLTE work...100% T- mobile speciallity....
You can flash it by yourself, but be sure you dont have phone with unlocked bootloader.... if you make it after, you loose IMEI and mobile is 4 parts only....
Thanks for that info and the warning! Did you try it yourself with LOS? I have already unlocked the boot loader to ...well, install LOS. But afaik it is possible to lock it again using flashtool. Is that what you did?
I have had many Z5 compacts.... first was with unlocked bootloader.... I did know nothing before.... so I have tried flash it..... not finished, error.... started phone, No IMEI at all.... only Wifi worked No Simcard read, so I used it 4 parts - crashed display.... and for study how to dissassamble all. It´s nice when you know how to dissassamble hole Z5 compact and reassamble new one
Since then I buy only Z5 compacts with factory locked bootloader, OEM locked, from normal users....VIRGIN phones they are perfect 2 flash.... also i have had one piece, there was Lineage os before to anroid 7.1.1 returned, opened bootloader... and it has non functional cameras and flash.... no hardware problem, it was because of unlocked bootloader and this Lineage OS. Somebody bought it from me to use it as a bike navigation
I have relocked the bootloader via Flashtool... but cameras were still kaput 4 ever.
Installing Lineage OS or unlocking bootloader can (or relocking bootloader after - I dont know) destroy cameras and flash lighter..... on 7.1.1 android. It will not destroy cameras on android 9. Fx sony XZ1 compacts..... but you will still loose some functions of cameras + codecs and so on.
If you do so, there is no way to fix it back....
Unlocking the bootloader no longer breaks the camera on Sony Xperia devices running Android Pie
Unlocking the bootloader of Sony Xperia devices running Android Pie no longer totally breaks the camera like before, but not every feature will work still.

Hi community,
as far as I read nougat has been torn back from sony. Anybody updated before and has a smooth experience? Would like to update too.
Downloading and starting flashtool does not give me the check updates tab, so is anything wrong or has the device to be prepared?
Does this way need root or unlocked bootloader or something else?
I hoped taking a virgin z5c and flashtool would fit to check for updates, find the device and firmwares according to, choose one of and flash?
Isnt it that easy? Any ideas when nougat from sony official will be provided once more?
Thank you
There were a couple of serious bugs in the Nougat release, hence the draw back by Sony.
Maybe in a month or two, we'll see a fully working Nougat ROM for Z5C.

I'd suggest to wait too. Backup TA, Root and use Xposed instead. The only thing that is a bit more handy is split screen mode. I have audio bugs and thermal issues running nougat.
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
https://forum.xda-developers.com/xperia-xz1/development/kernel-sony-xz1-23-january-2018-t3739586
I think it is better to search an equivalent kernel for the Compact due to the screen drivers.
So I unofficially unlocked bootloader in my Redmi Note 3 Kenzo and installed Oreo based Havoc OS. All is good except camera and flashlight. I suspect it's because I flashed wrong firmware. I don't even know if you need different kernel for officially and unofficially unlocked phones. I'm pretty new at thing. It'd be great if someone help. Thanks.

You need to format your phone, on kenzo there is no diffrence offical or unoffical, there was upon a time but not anymore
hello,
since the Honor 9 isnt getting any security fixes anymore what can we do
about the BlueFrag security hole?
https://www.andreafortuna.org/2020/...-critical-bluetooth-vulnerability-in-android/
It seems right now the only chance would be phussons android 10 GSI
https://forum.xda-developers.com/honor-9/how-to/android-10-t3993461
since there are no Custom Android 9 or 10 ROMS with latest Google Security Fixes - correct?
If someone figures out how to bypass the bootloader that huawei put, then we can start doing this roms thing, until then, unfortunate people like me are stuck at a locked bootloader.
Well i can technically do the whole process of flashing my board again using dc unlocker and then unlocking my bootloader while I'm at it, but that's too much hassle, man, plus you need some money to spare. It's not worth it anymore unless you absolutely have to, I'm just happy with a working phone lol
thanks for answering - i'm also stuck at EMUI 9.1
and with this method?
wouldnt it be free?
https://forum.xda-developers.com/honor-9/how-to/downgrade-unbrick-honor-9-imei-fix-t3934363
then we could try some of theses ROMS out

Nope, u have to pay for it, and yeah, i'm waiting for them to find an exploit on the security that huawei put in their gpu turbo update, bec. that's the root of our problem, i heard that if you downgrade to a non-turbo firmware, it's gonna brick your device, so might as well be patient until the guys at dc phoenix figures out how to read bootloader codes on emui9.
Also I saw that openkirin has hw buttons fixed, i think it's the capacitive buttons fix that people often lose bec. of installing twrp, so i'm excited for that day that we can install openkirin roms

Hello anyone, I am the new comer of the XDA. Nice to meet you here. Let move on to my questions.
I have a HK version Xperia 1 III(XQ-BC72), and I love the device.
However after I received and upgraded to Android 12(61.1.A.1.149), the nightmare comes.
There are bugs on Android 12 and I does not like the UI and some of UI interaction logic.
It makes me so upset and very regret it.
So that I have an idea to downgrade the firmware from Android 12(61.1.A.1.149) to Android 11(61.0.A.23.20).
I already seen the "How to Guide" to know how to unlock and relock the bootloader, and flashing the firmware so on.
But I still some question here. Hope someone can answer...
1. DRM things
While unlock the bootloader, DRM will gone.
But relock the bootloader and using Xperia Companion to repair, most of the DRM may come back that I know.
However, using Xperia Companion to repair will update to latest firmware.
So, is there anyway to get back the DRM without using Xperia Companion?
(Or, does Xperia Companion repair is the only way can get back some of DRM keys?)
It is good if the DRM key can back.
2. Exclusive Functions
Does unlock and relock the bootloader will cause some function loss?
The Xperia smartphone have a Trim Area(TA) that I know. If the TA is missing, some functions will be loss.
I know Xperia 2021 device does not have hardware function loss after unlock. But how about the exclusive function such as Dolby, DSEE, Creator display mode?
I does not want there are any function loss, include exclusive function.
I know unlock the device may void my warranty, so on I will not unlock my device and take this action before my warranty is over.
Even through I does not have a plan to start it yet, but It is still good to know everything before get started.
Hope someone can answer the question, thanks.
You do realize that if you "downgrade" that you will no longer receive OTA security updates?
Best thing to do is get used to 12. Learn it and after a few days you will not even notice the difference.
Either that or try and find a custom ROM that will receive updates like LineageOS.

Android 12 on xperia have some big issue, for example the latest android 12 version on Xperia 1 II will never play 4k HDR video. If it's only about the UI i agree with you but right now there are same broken features

I know what I am doing here, that why I am asking for it.
I love stock Android and Sony function so that I choose Xperia.
If Android 12 is a great update, I don't mind it, even I can continue to stay in Android 12.
Android 12 changes some UI logic and UI design, I can try and learn with no problem.
But Android 12 is very buggy, it such a pain. That even worse than Android 11.
That is the main reason that I want to rollback my device system to Android 11.

Nope, I tried to flash the older firmware without unlocking the bootloader.
But it failed, a bootloop appear. Because the Android Rollback Protection is here.
I just do some research here, it need to unlock the bootloader to reset the vbmeta rollback index to 0 for flashing older firmware.
Seem unlock the bootloader is the major step to downgrade the system.
