Problems here (fresh install of romaur 4.0) :

- Baseband .314 provided in OP seems to be rejected by my d6503LB (still diplayed xxx-09 instead of xxx-10)

- Unable to use wifi (due to baseband mismatch ?)

- Build number still shows Romaur 3.7

- Changelog missing for v4.0 in OP
[Xperia Z2 Android Development] :
I have a similar problem. Installed .314, but still on Romaur 3,7, no recovery, wifi doesn't work. Can't install any recovery now. My phone is basically bricked.

---------- Post added at 10:24 PM ---------- Previous post was at 10:21 PM ----------

Can anyone please help? I need my phone for work and its unusable right now.
[Xperia Z2 Android Development] cosmic76:
I had the rom 3:03 Monxdfied .438 ...

- I installed the 4.0 rom via recovery

- Without shutting down I installed via recovery xzdualrecovery

- I turned off xperia Z2

- I flashed through Flashtools the kernel and the baseband of .314

- Disconnected from the PC and reboot

everything is perfect

Do we need to untick Anything when flashing kernel and baseband?
[Xperia Z2 Android Development] cosmic76:
yes but you must download this one http://marco-kretz.com/z2/RomAur/RomAur v4.0 XZ2 AROMA.zip tks to "Originally Posted by zantekk"
[Xperia Z2 Android Development] Silvio Scarani:
Could you tell which you installed it and where did you download? I'm just the one of .402.
[Xperia Z2 Android Development] auras76:
Make a full wipe on aroma

Install v4.0

Install dualrecovery

Power off and install kernel 314 with flashtool

Reboot.

Check md5, should be v4.0 and baseband 10.

[Xperia Z2 Android Development] muhammadshais:
Try to flash another baseband other than provided in OP, the Korea one is giving problems in other regions, I had the problem and resolved it by installing advanced stockkernel from the op as it is for 438 so it will give boot loop now install the 318 kernel with flashtool but tick the skip baseband option in the right column, it should work now

---------- Post added at 06:52 AM ---------- Previous post was at 06:47 AM ----------

Here are the steps for those having problems

Mine was unlocked bootloader with Rom aur3.2

Transfer the zip file from op to recovery

Install wiping data and system

Go to recovery advanced options and turn off

Install 318 kernel with baseband

If u have signal issues or network not working

Install 438 advanced stock kernel in fastboot mode

Power off the device

Install 318 kernel from op this time by ticking exclude baseband

It will work like a charm:)
[Xperia Z2 Android Development] :
For the people having wifi/data problems, I suggest flashing the unbranded Candian version of the 314 firmware. The one OP linked to has problems.

Everything seems to be working fine finally, on the latest firmware rooted. Only (huge) problem -- at some point, somehow, my titanium backup was erased. TiBu cant find it. All my data is gone.
[Xperia Z2 Android Development] tyteen4a03:
Mixing 318 kernel with 438 baseband... clever. I have the HK variant though.

Will try anyway.

can you provide download link for that Canadian version? Thanks

Hi All, I did a full wipe coming from stock rooted .438.

[Xperia Z2 Android Development] neyz:
Can anyone confirm or not the eventual battery drain some people mentioned?

I'm on 3.6 and don't want to full wipe if it's to have battery drain.

Also, what would be the best way to quickly reinstall applications / settings after full wipe? Is titanium backup safe to use?

Thanks!
[Xperia Z2 Android Development] Silvio Scarani:
Italian Z2. Full wipe: user data, cache, Dalvik, format cache-format data-format system. Installed RomAur v4.0, XZ-Dualrecovery (via CWM) and kernel baseband .314 generic Thailand (Thailand kernel for an italian phone? Yesss.) via Flashtool.

Works very fine!

:victory:
[Xperia Z2 Android Development] visitor29:
Yeah titanium is what I'm using. P.s. Personally I decided to rollback on 3.6 until doomlord will give some happiness on kernel for 314 or who know maybe straight away for 4.4.4, will see...no point to rush, can't see major differences from 4.0 & 3.6...
[Xperia Z2 Android Development] nexx67:
Can't tell right now for battry drain because high usage of my phone today... but it seems ok :)

I use Titanium backup to restore user apps+data, and only SMS data for system apps (you can have lot of trouble restoring all system apps data as far as I know)
[Xperia Z2 Android Development] Angeloid:
i got a bootloop after install v4.0

any solution?
[Xperia Z2 Android Development] nexx67:
Download romaur once again (in case of corrupted file), make sure you have a d6503, put zip in your SD card, install it with full wipe and don't forget to flash .314 kernel+baseband.

If still the same, use flashtool to flash a stock rom (ftf) and start over.

Hope it helps

[Xperia Z2 Android Development] SwannyBhoy:
Can you get into recovery? If so re-download the rom and check the md5sum with the recovery and with the OP and then reflash.

If not, back to square one like me

Just flash the kernel and modem (After flashing the rom), from the german FTF and axclude everything else

---------- Post added at 06:51 PM ---------- Previous post was at 06:50 PM ----------

Did you flash the kernel and baseband from the .314 ftf?

---------- Post added at 07:00 PM ---------- Previous post was at 06:51 PM ----------

For people having problems flashing the rom (Bootlops, no signal, etc.), try the following steps.

1 - Make sure your phone is D6503

2 - Enter recovery

3 - On aroma installer do a Full Wipe

4 - Flash rom

5 - Flash Dualrecovery

6 - Power off the device (on advanced-power off)

7 - Flash the kernel and baseband from the .314 FTF of your choice through flashtool. Choose only Kernel and baseband, exclude everything else and wipe nothing (Download here)

8 - Power on

[Xperia Z2 Android Development] seh6183:
So do you think MPDecision was the reason for the battery drain? You clearly are not having any battery drain. Those results look great. Also what region is that .314 kernel from? I'm in the US so want to male sure I flash the proper .314 kernel. Im thinking the Canadian one might be most compatible for the US.
[Xperia Z2 Android Development] hirikarus:
Q : So do you think MPDecision was the reason for the battery drain?

A : not at all on 3.7 i used MPDecision too but battery still drain. but on 4.0 it's different maybe it's because stock kernel.

Q : Also what region is that .314 kernel from?

A : Thailand and im from Thailand so lucky !!

[Xperia Z2 Android Development] farfromovin:
Alright, I'm new to Sony phones but I gotta throw in my. 02 here. If it's a. 314 kernel it's a freakin'. 314 kernel. Doesn't matter if it's from Germany or Thailand, it's a kernel for a specific firmware.
[Xperia Z2 Android Development] dangermind:
I had no LTE after flashing 4.0.

After flashing 4.0 again i shut down the phone and flashed the german .314 ftf file everything excluded except kernel and baseband.

Have you tried flashing baseband from another ftf? Did you download the apn settings for your carrier?

TWRP from .153 dual recovery seems to be fixed for .314 firmwares.

I also updated without wiping data but from a .402 based monxDIFIED but used FTF instead of zip for .314, since I already had one downloaded. This did require rerooting/recovery so maybe more work but less time(not needing to d/l large file off slow host).

Glad to know there is a less painful route to getting 4.0 on my 3.6-loaded Z2. My question is, though, why? 3.6 seems to me the most stable and, so far, best battery life of any ROM. Have you found any particular advantage over 3.6? What's your observation so far on battery life, especially screen-on times? Any issues with LTE, wifi, etc.? Maybe some of the problems reported with losing wifi and LTE been having are locale-related? I tried flashing various .314 ftfs and they all gave me big problems, I ended up going back to .402 baseband for the meantime...

Thanks for any feedback/input.
[Xperia Z2 Android Development] :
if anyone still have the 3.6 link or has it on his computer please upload it and PM me the link, i'm on 402 UB and i was going to test the 4.0 but i have read that there's a lot of you guys having problems!
