Yes you have to unlock your boot loader... But make a back up first of your TA image, before unlocking..and your gonna need some files in your PC to do the process. You can find it in you tube.
[Xperia Z2 Android Development] lieblingsbesuch:
Thank you... i got to manage unlocking the bootloader, installing TWRP 3.2.1-1, and wipe DALVIK, DATA etc. If i want to flash the rom nox, it says "Updater process ended with ERROR: 255". Searched the web like 2 hours now, didn't find any clue.

I'm about to install from the sd-card since there is obviously no OS on the phone now and i can't transfer the rom to the phone.

Does anyone have any clue?

---------- Post added at 05:09 PM ---------- Previous post was at 05:01 PM ----------

I found the "issue". It must be the rom offered because The "Carbon Rom from 8.1. just works fine.
[Xperia Z2 Android Development] z7kazanova:
you don't need to do all this things u just need to Turned off voice match on smart lock

If it dosent work. turn it on, and reboot ur device then turn it off once again

[Xperia Z2 Android Development] omarbeco:
Lol i think they are updating it yearly
[Xperia Z2 Android Development] Cygmon0:
I think he is busy or working on Project treble for our device .

don't complain.

If you want updates, go to carbon, otherwise, no one has forced anyone to use this ROM .
[Xperia Z2 Android Development] xperia1-2:
Please don't mind, that's just an expression of over-zealousness. We know that developers have their own lives and work. We just can't wait to be too bad.:o

I get low signals of wifi on both rr and carbon ROM compared to stock mm. Any solution to increase signal strength by flashing files?
[Xperia Z2 Android Development] asifulhaq:
Some charging related questions. How much amps are others getting with this rom using stock charger?

Is quick charge possible with the latest build by default?

Also, can someone suggest a good fast charger that would works well for you?
[Xperia Z2 Android Development] mufunyo:
Just upgraded to this from Nougat on my Z2, battery drains insanely fast, it can't even charge fast enough to keep up with the battery drain. AudioFX keeps crashing. I can install Xposed Systemless (Magisk), but it doesn't work. Going to restore my TWRP backup of 7.1 RR.
[Xperia Z2 Android Development] kutysam:
Just my 2 cents on two things.

1) For those saying 'my charger doesn't work for quickcharge etc.'

I can confirm this rom supports quick charge.

Personally, i don't trust software battery to tell the charging rate.

https://www.aliexpress.com/item/USB...ower-Meter-Text-Voltmeter-24/32712104350.html

Get an item like this and see if it reaches 9v. Mine reaches 9v and ~0.8a --> 7.2w ++

Quick charge requires a QC 2.0 compaitible charger and a good cable. If you get a 28/28awg cable, you probably can't quick charge.

28/24awg will work.

2) Those who upgraded from nougat and feel extreme battery drain... wouldn't it be better if you guys just clean flash the whole thing? This is a developer rom and i believe the developer is trying his best to get this up and running well. Things like getting it optimal from an upgrade from nougat are usually lower priority tasks.

Additionally for 2: I can confirm that deep sleep is not present on thsi rom yet. I believe somewhere along this thread, OP has mentioend this.

Also, i saw this in logcat, which could be the cause?

06-24 15:05:13.388 2392 2607 E QCOM PowerHAL: Failed to acquire lock.

Additional edit:

1) I can confirm Carbon rom has quick charge too

2) Carbon rom has deeeeep sleep too.
[Xperia Z2 Android Development] mufunyo:
I always do a clean flash. Backup all apps using Titanium backup -> full wipe -> install ROM -> restore apps.
[Xperia Z2 Android Development] Skolotaie:
Greetings

first off,i installed the rom totally clean,step after step like mentioned.

Magisk v16 works and also no big battery dran or other bug's found yet.

But when i open the App-right's managment it fc's :c

Any way to get this fixed or someone else faced it?

But all in all very smooth rom thank's dear Dev
[Xperia Z2 Android Development] lieblingsbesuch:
Also did a clean flash and had no problems w/ battery life whatsoever.

Problem must be the Apps u installed.

[Xperia Z2 Android Development] amiralisaemi:
On this rom after using some software such as video player, the mobile is very hot, which quickly reduces (drain battery)the battery life.

This happens even with the update of some software such as Google Play or Google service.

Is this normal?
[Xperia Z2 Android Development] PixelSoul:
Same here, even with basic tasks :rolleyes:
[Xperia Z2 Android Development] ryan.vandalz:
No,its not normal.

I dont have that issue,try clean reinstall rom may help you.

---------- Post added at 10:35 AM ---------- Previous post was at 10:34 AM ----------

[Xperia Z2 Android Development] wadoo24:

Imagine you play with it ? The phone zil burn for sure
[Xperia Z2 Android Development] amiralisaemi:
Even I use image editor like Pixlr, phone very hot.

Why!!!!!

---------- Post added at 11:50 AM ---------- Previous post was at 11:47 AM ----------

Sometimes, because the mobile is very hot, the charger can not charge the phone
[Xperia Z2 Android Development] koraymers:
checking min frequency may help reduce heating issue I guess

if anybody face with high temperature issue than you can install kernel auditor from play store and set cpu MIN frequency to 300 mhz

hope it'll help

Hello, what is your SoT time? (screen on time, you can check it in settings > battery).

btw I'm on carbon right now but I just try help to fix yr issue. I suspect ur cpu frequency thats why I wrote a suggestion on rr topic

didn't u check cpu min frequency
[Xperia Z2 Android Development] xperia1-2:
I doubt your battery data very much. The new mobile phone can't reach the endurance level. I doubt you have been charged halfway.
[Xperia Z2 Android Development] koraymers:
new phones can reach up to 6 hr so 4hr 10mins isn't incredible extreme extraordinary fantastic or supernatural.

The thing is know how a battery works and how to use it.

check it out your cpu governor and set a limit to screen off cpu frequency

Also When Connected To A Charger The Phone Lights Up And Says Charging But It Doesn't Increase In Percentage

But It Charges When You Turn It Off ..

help Please ...
[Xperia Z2 Android Development] xperia1-2:
The point of the problem is that you only consume 14% of the power in 4 hours, if you Consuming 100% of your power, you will be able to brighten your screen for days, and the big cell's new cell phone will not do it.Four years ago, the old mobile phone Z2 could not do it. I doubt it.
[Xperia Z2 Android Development] koraymers:
you don't know how to read data, nevermind
[Xperia Z2 Android Development] xperia1-2:
The reason for the game crash has been found by the carbon author. I hope that the RR developers will take the time to update. I still like RR's various configurable items.:eek:
[Xperia Z2 Android Development] wadoo24:
I guess i will switch to that rom , weekly update sounds good for me , rr is great no one doubt about that but it's take too much time to update , more then 60 days , xperia z2 is old phone and he is getting older in ower hand each day we use it , so that time of waiting is against us .

What is the point to have exclente rom after one year from now ? Maybe on that time ower phone died or we will died who knows ? Loool .

Is simple opinion fan Boy's dont attack me . i ask for nothing alse

System should not be formatted as F2FS.

If you restpre data properly, there will be no data loss.

Was zzmoove governor in the new boot.img ?
[Xperia Z2 Android Development] mimo.aridi:
Yup. Even on last build.

I flashed boot.img of 7/5 build ani got it back.

And for those who are experiencing twrp lag just flash twrp 3.1 img again and lag will be removed. U can use rashr app instead of using a pc and fastboot.

After a year of running Android 7 and Android 8, I installed Android 6 again.

Nougat and Oreo reduce battery life and are not suitable for daily use on z2 mobile phones.

These two will cause the phone to warm up, which will cause the battery to be empty.

I'm try several time to clean flash.

This problem is not specific to this ROM.

All Android 8 and 7 Rom's have this problem on my mobile.

I asked several questions for this problem, but nobody answered......

And now I flash stock Rom ( marshmallow) on my mobile and battery is perfect.
[Xperia Z2 Android Development] dikme:
Same here [emoji22]️
[Xperia Z2 Android Development] Cygmon0:
That's good man...

I mean. You can use it as a bomb if someone is trying to bully at you!!

You can really make benefits of the device being hot
[Xperia Z2 Android Development] wadoo24:
Yes i agree , this oreo make the device heat , i reduce the frequency of cpu to 1190 mhz , even with that and the device get little bit worm but i had perfect battery time , 7 hour of screen on time , perfect ;)
[Xperia Z2 Android Development] Cygmon0:
Yes..

I saw a lot of developers says the heat problem in android 8.1 is common with lineage os ( and based on that )

So it's not only our Z2
[Xperia Z2 Android Development] Taha_moahammed:
How can i do that? ?
[Xperia Z2 Android Development] ebram96:
Does this rom has any current bugs ?
[Xperia Z2 Android Development] wadoo24:
Kernel auditor app with root of caurse , i minimaize the frequency of cpu to middle , like that you will lose the preferments of the device and you will win power ( battery) and you will reduce the overheating of oreo z2

---------- Post added at 10:32 PM ---------- Previous post was at 10:29 PM ----------

Many bugs still on this rom untill now , the worst bug is overheating of the device on simple daily task , this rom right now and speciely on summer is not safety to use at all .

You will have and must to reduce the frequency of cpu to middle to reduce that heating little bit.

You have to wait for the devloper to fix that problems maybe after one month or two or one year , only god know whene
[Xperia Z2 Android Development] ebram96:
Then why isn't there a "Bugs" section in the thread? and what rom do u suggest ? The battery life is a priority to me
[Xperia Z2 Android Development] Cygmon0:
RR is unmaintained ( at the moment)

You can use AICP or CARBON.

Those two has updates. So far no bugs. Only device heat, and it's common in lineage 15.1
[Xperia Z2 Android Development] ebram96:
What about the battery
[Xperia Z2 Android Development] amiralisaemi:
In carbon ROM and aicp ROM battery and CPU is like RR ROM.

This is the common problem lineage 15.1

Lineage is the based of all this rom
[Xperia Z2 Android Development] ebram96:
Is it the same for Android N ROMs ?
[Xperia Z2 Android Development] amiralisaemi:
Yes. I tested Android 7. It has a problem. Because it's based on linage 14.1

Their kernel makes the phone hot, because it's always use half the cpu.

However, the makers of these ROMs are great to provide these ROMs for the Z2 mobile.

Thanks for all of them
[Xperia Z2 Android Development] wadoo24:
you have to root the phone an install thirs kernel app ( kernel auditor) and reduce the ferquencey of cpu is simple , you will get more battery time
[Xperia Z2 Android Development] ebram96:
I read about that too, but according to other users the battery and CPU performance are not the best :(
[Xperia Z2 Android Development] :
Hey... Sorry for not building for a while :) exams and a new phone kinda limited my time to spend on this, i may make a build soon

as for heating.... a logcat of just general usage might be useful.
[Xperia Z2 Android Development] Cygmon0:
Glad you back safe :)

Good luck
[Xperia Z2 Android Development] wadoo24:
I already did that there mounth ago , and you told me that's normal , but now after use this rom and compared to the stock one , i am sur that's not normal at all , the device is heating even with half frequency of cpu !!?

I will send other logcat tomorrow , hope this time that problem it will be slove , thanks
[Xperia Z2 Android Development] xperia1-2:
