Hi folks,
Currently using an Xperia Z3 Dual D6683 running Lollipop 5.0.2. It's rooted with a locked bootloader. I've been waiting for ages for Sony to release the Marshmallow upgrade for this specific model, but I've heard there isn't gonna be one (dunno if it's true or not).
So I've been thinking, since the D6683 and D6633 variants of the Dual have basically the same hardware, is it possible for me to flash the D6633's Marshmallow ROM directly to this phone? Would it work fine, would it have some minor issues, or would it brick my phone? Anyone tried this yet?
Hoping for your feedback guys. Thanks a lot!
@xxiteruxx
I don't own amy of the models D6633 / D6683, but I've done some search on it and it appears that the D6683 is the Hong Kong DualSim variant if I'm not mistaken.
Therefore the difference to the D6633 would only be the radios, as the d6633 is capable of European LTE networks and the D6683 isn't (only two).
I don't want to guarantee anything, but you could try and edit the update-binary/script of a D6633 rom and match it to your model and flash away. I assume you won't get the network working, it'll error probably.
That's my guess, hope it helps.

I've just done exactly as you described (d6683 flashed with d6633 marshmallow) and haven't had any issues at all. However, this is probably because both phone's LTE bands are what my carrier is on. Others (US carriers?) haven't been so lucky.
Anyway, here's what I did on my own d6683:
1. downgraded to KK using flashtool, d6633 FTF file; loosely following this guide:
http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
2. rooted with giefroot
3. installed Dual recovery
4. flashed MM Rom zip (d6633)
5. flashed recroot v4
6. wiped cache
Everything's been great thus far. Only snag I hit was when I got into a bootloop after I'd first downgraded - I just flashed the FTF again but made sure to wipe APP_LOGS and USERDATA.
hey @neverborn
Thanks for the tip! I did my homework and found D6683 utilizes LTE Bands 1, 3 and 7. Where I am, the carriers use LTE Bands 1, 3, 5, 7 and 41. I also checked D6633 and saw it supports those bands, except for 41 which really isn't much of a problem, I think. I'll try your method and will reply back with the results. Cheers!
Okay, was doing fine until I began rooting using giefroot. Always getting the message that my device is unrooted. Tried it 3 times, and still it failed. So, I used Kingroot instead, and was able to install Dual recovery. Now succesfully flashed MM, wiped cache and dalvik just to be sure. Rebooted successfully, but now I can't root using Recroot V4. Still trying to figure this last step out.
Okay, I'm stuck. I'm always getting this message:
"* daemon not running. starting it now on port 5037 *
* daemon started successfully *

Rebooting into TWRP recovery ...
Press any key to continue . . ."
After that the phone just restarts and doesn't go to TWRP. Tried to do everything all over again, still the same thing. Any thoughts?
Finally figured out what I was doing wrong.
1. After downgrading to D6633 KK, I didn't untick "Verify Apps", that's why Giefroot failed to install SuperSU
2. This is one of those moments where you keep on kicking yourself for not figuring out the obvious. After flashing D6633 MM, I rebooted immediately, extracted Recroot V4, connected my phone to PC, and ran install.bat. That's where I keep failing. Then I read your instructions again, and you said "flashed recroot v4", not "extract". So, banged my head against the wall for being stupid, and tried everything all over again. This time FLASHING RecRoot after flashing MM.
And it worked! Successfully flashed rooted MM for D6633 on my D6683. LTE network on both of my SIMs also work the same as before. I'm now a happy camper.

Good to hear - I hope banging your head didn't hurt too much
I just wanted to share my experience updating my d6683 Lollipop to d6633 MM.
What I did was I downloaded MM ftf from this link http://forum.xda-developers.com/z3/general/stock-marshmallow-6-0-1-build-23-5-0-t3357509
downloaded the flash tool from this link https://depositfiles.com/files/o1qgv8a61
then flashed the phone and I'm happy that I was able to upgrade to MM without having any problems.
Now which bands can you use? Can you use lte band 20? See in the service menu.
The carriers here don't have band 20, so I'm afraid I can't answer that. What we have here that's supported by D6633 are bands 1, 3, 5 and 7.

By saying E6633 you mean the Xperia Z5 Dual? I think that's just a typo but in case it wasn't, you can't flash an Xperia Z5 Dual ROM to an Xperia Z3 Dual phone.
But in case it was a typo, then YES, flashing the D6633 ROM to the D6683 model will also change the model number in the About menu. I don't have a shot of what it says before, but here's what my About menu looks like now.

Glad to help, and happy flashing. Been using it for over a month now and no issues so far.
What I did was I downloaded MM 23.5.A.1.291 ftf from this "xperiablog.net"
downloaded the flash tool then flashed the phone and I'm happy that I was able to upgrade to Marshmallow (with STAMINA) . Everything work OK.
Sorry, I can't see it. I was able to get decent LTE speed without any problems

your z3 dual d6683 from lollipop 5.0.2 you flashed straight to MM rom for d6633? no need to flash first to kk for d6633 firmware?
I also have a D6683 and I flash MM roms for D6633. It works quite good but sometimes I have signal loss which I didn't have with stock original LP rom for D6683 (5.0)
Did anyone notice the same ? I tried to flash original LP rom amss 1, 2, fsg, system/etc/firmware folder and system/etc/customization but the second sim get disabled somehow. I can't figure why I get this disconnection and how I can use the D6683 original firmware files...
Is it possible to flash my Z5 premium E6853 over to the Japanese z5 premium S0-03H docomo firmware? I will be moving back to Japan soon. I tried downloading the firmware with xperifirm and flashing it with flashtool but I ended up failing and bricking my phone and having to flash back to my original firmware.
I forgot to check all the boxes in wipe. Would that cause it to fail? Is the SO-03H firmware even compatible with the E6853? Appreciate any help in advance.
This is the error I'm getting:
Processing of partition.sin finished with errors.

Have the same issue, it seems not.
It is possible from Docomo/etc.. variant Z5 phones to use Global one but not the reverse.
I also tried to convert a ftf to flashable zip, but I always get "failed to map file" in TWRP.

Yeah it's very odd. Seems to be the same hardware but for some reason only works one way and not the other. Possibly some part of the firmware could be modified to work on the global version but that's beyond me.
You plan to get a domoco subscription or roaming your current one ?
It should work anyway (at least phone calls and internet)

Subscription. I never roam even when travelling. Here in Taiwan, all phones are sold unlocked with removable sim cards. So I usually apply for a temporary sim card or WiFi rental box when I go abroad. Since I'll be living in Japan and going with Docomo, I thought I'd flash over to the Docomo firmware to avoid any issues. I guess it's not that necessary.
is any workaround to modify oem.sin? i just want to add my operator VoLTE settings. Thanks
Did you ever figure this one out?
Its impossible to edit a .sin file and flash it using flashtool.
You have to do it via a custom ROM, hence a rooted device is needed

Is it possible though to take an OEM.sin from another firmware variant and flash that so I can get my VoLTE 'settings'

hmm,, I do not know, you can try it. Just swap the necessary .sin files using flashtool and try to flash it. there are 3 outcomes.
1. it will work (Great)
2. It will not flash (No problem)
3. It soft brick s your phone, so just flash a .ftf to restore your phone.
It works to flash oem.sin from other regions firmware with no problems , my problem is that my operator just released VoLTE and VoWIFI and Sony didnt add the settings in their firmware and the only way to do it is if i root the phone or if i could edit OEM.SIN before flashing (but seems thats not possible). My operator doesnt sell any Sony phones so probably will take a long time till my operator will contact them to add the settings in the firmware or maybe not at all or maybe only for latest devices or for the future models (i cant know that). Sony does have the VoLTE settings in like all EU firmwares and VoLTE + VoWIFI in specific operator firmware but only for Orange in my country and im using some other operator.
Edit:// just get the firmware that has your operator settings then flash only the oem.sin from it with flashtool , i did that with mine and i had no problems.

I have a problem in that my phone was never released by my operator! Do you think it'd be possible to get an OEM.sin from another phone altogether? They have released both the XZ Premium and Z5 Premium (I have the X performance). Alternatively I think if I edit the modem.conf I might have a way to get VoLTE too

this is experimental try replacing firmware folder with elabel-Gxxxx-india-row_xxxxxxxxx_41.3.A.2.XX_S1-ELABEL-LIVE-DE8D-PID1-0004-MMC.sin and also you need to manually extract update.xml from indian firmware.... if it is set to unpack automatically in xperia firm it will be replaced by update.xml from the big file that size 2.6GB , you need update.xml from the indian firmware placed inside 46MB file
FYI without unpacking there will be like 3 files
one size 2.6 , other two size 46mb and 1.2mb
we need update xml from 46mb file and sin from 1.2 mb also dont forget to remove elabel-Gxxxx-yourcountry-row_xxxxxxxxx_41.3.A.2.XX_S1-ELABEL-LIVE-DE8D-PID1-0004-MMC.sin

Unfortunately only phones on my provider which has VoLTE support for Xperia xz performance and I can't yet extract the sin from that firmware
I have edited the relevant files on my device. Is there any way to force the phone to pick up the new oem settings? Will it require a format (reset to get it to work)?
UPDATE : reflashed phone via Flashtool. Excluded oem partition from flash and now have working VoLTE

which files have you edited ?? can you explain step by step please?
Can you please explain how this was done in more detail?
Is it required to unlock bootloader or root the device? I want to keep all my DRM keys but just enable VoLTE (and VoWIFI if possible).
Guide is here. It should apply to any device that has an oem partition provided you have the relevant files. That being said I haven't tried it on any other devices https://forum.xda-developers.com/xp.../guide-enable-volte-operator-handset-t3816565

Dear Friend,
How do we flash only oem.sin. I need volte on sony xperia x compact
Is this will be ok?, because Xperia 5 have 128GB and AU version have 64GB.
anyone have tried it?
Please don't flash if yours is a different model as it may break your phone. Only of the same specs model.

when I hear the word AU,I think that you are from indonesia tercinta merdekalah katanya
Huh. Please don't attempt to do it. My Xperia 5 bricked after doing it. And since the phone had some USB issues, getting into flash mode again was very difficult and consumed around 2 hours fiddling with the volume keys. Because the red light just blinks every 2 seconds or so. No green light after connecting USB while pressing volume down. Finally when I got it in flash mode, flashed the SOV41 AU version which brought the device back to life.
No harm in trying it (in my experience). Just give it a try and if it (bricks) doesn't boot, force shut it down, put it in flash mode, and reflash the original ROM with NewFlasher, (Don't use FlashTool) and boom, back to working again.
Edit: why have I just replied to an almost 3 year old thread at 00:53 in the morning... Good damn it lol.
ROMs that I tried but failed :
SO-01M NTT DOCOMO JP - Signature error, not even flashed.
J8210 Customized UK - Bricked
901SO SoftBank JP - Bricked
All I was trying for to use 4G network as Jio Sim works only in 4G. Even though a toggle was available in the AU version to enable 4G, it didn't worked. It can't even connect to network by manually selecting. And 4636 method don't work.

Replace AU oem files with attached files. Flash with new flasher. Probably no AU messaging app after flash. so you need to install either google messages or use attached au original message app apk.

Hey did you flashed the global rom? If you did see if it lets you unlock the bootloader. If it does then you can just flash a custom rom and get sim card support using root. If my method works inform me. I will do the same thing.
Hey. I unlocked the boot loader with q unlock tool. My doubt is that any global rom comes with single sim support?

If just you want to have android 12, you can flash SOG02 KDDI.
Did anyone manage to get android 12 running on A002SO(SOFTBANK) ? Whats the best solution and option? Or what's the closest firmware to A002SO 8/128GB single sim or any cheaper option for us to get bootloader unlocked? And even of we opt for custom roms wont the single sim cause issues?

Why you need Global Rom ? For Volte Vowifi ? For that you just need Global Modem Configuration which is very easy. Download SEA firmware and copy Modem Fils to Sogo or SoftBank or whatever your device is. Just copy these file to your firmware and flash it. That's it I will get Global Modem and 4 singles issue will be solve. Plus if you want Volte and Vowifi then there is simple track u have to run one small app and you will get everything. Personally using SOGO2 Xperia 5 ii in UAE and I got everything except 5G network. Trying to solve it also. Soon INSHALLAH.
