I've been using the pac-man ROM for over a year now, but it's a very old version, buggy and outdated. I wanted to try Kit Kat or basically just find a stable ROM, but pretty much ALL of the ROMS i've tried end up unable to find any mobile network or display the SIM card as invalid. Even when I search for networks or try to add a network manually, it still doesn't stick. Occassionally it'll even find the my local network when I go in settings and do a network search, my network being that of China Unicom, but it always results in failure to subscribe, please try again later. This has happened on a good 7 out of 8 ROMS i've flashed. The ONLY ROM i've ever been able to find a network on and thus make it usable has been the old 2013 pac-man 3.99 build. I've searched the forum and google for answers, such as flashing a particular modem or whatnot, but haven't found any solutions.
Does anyone have any ideas? It'd be greatly appreciated. I really need an updated ROM! :fingers-crossed:
If it matters:
Network: China Unicom
I've tried: 4.4.4 CM11, Stone UI hD3, Carbon KK Unofficial 2014-12, CM10.2 nightly, CM 11 M9, KitKat CarbonCN, PC Honami KK RC3, and Xperia Z Z1-1.4.
Only working ROM so far: pa_togari-3.99-RC2-20131104
To use the more modern ROMs you will have to be on a 4.4.4 FTF or you will get baseband issues ie SIM cant connect to network etc

It's been over a year since I unlocked and flashed my phone, and I haven't done any flashing since, so I kind of forget some of the procedures and technical aspects.
I'm going over the FAQ now, and one thing it says is "Never Flash a FTF to a ZU GPe." What is a GPe, and how can we make sure we are not using it?
It also mentioned I should use Sony PC Companion to update to the newest firmware. This means it will update to 4.4.4 FTF right, or do I need to find this and flash it manually? Likewise, after I'm on 4.4.4, I assume my phone will be reverted back to stock. Would I have to root it and unlock the bootloader again?
I remember when doing all this for my phone the first time, since my phone was a Chinese model, 6833 I believe, I went through hell and back for several weeks until it flashed and took the current ROM properly. Something about buggy firmware in that paritcular model, although it's been so long I forgot all the details. I'm worried that I'll run into a similar situation with 4.4.4... Thanks for any help, truly appreciated.

I tried to update to KK via Sony Pc Companion, but it says my phone is up to date. I assume it says that because it's not seeing any official firmware, due to the flashed ROM. Even when choosing the option to "repair my phone" which says it will re-install the latest available firmware, it states that there is no software available for my device. If memory serves me correct, I must first flash back to my oldest stock firmware that came with my phone, then I can use PC companion to update to KK, and then maybe unlock bootloader and root again, and then I'll be able to flash new ROMs and have a working mobile network, does that sound right?
Out of curiosity, since it's 4.4.4 ROMs that don't seem to work (network wise), doesn't that mean 4.3 ROMs should find a network just fine?

I cant remember where/when the baseband changed, it has been updated several times. I would just go straight to 4.4.4 and not worry about PC Companion - Just use the latest flashtool (http://flashtool.net).
Grab a 4.4.4 (aka x.x.x.108 or .118) FTF from the FTF thread in the dev section and flash that. That will wipe all user data (so back it up) and install a new /system image. You will have to root the device again abut 4.4.4 is easy to root now with the easyroot tool. Then you should be on the latest baseband and all the new ROMs should work - 4.4.4 and 5.0.x
Thanks blueether, I'll give that a go and report back (hope you don't mind). Here's hoping (since i know the 6833 chinese model is finicky)...

You mentioned I should get a *.108 or 118 in order to get the ROMs working again (mobile network wise).
I found in the FTF repository: STOCK ROM] [FTF] Xperia Z Ultra 6833 14.4.A.0.118 "VodaFone UK" and also "SRF FR".
I'm using a 6833 in China, however. My guess is these wouldn't work because they require different networks.
Doesn't matter? Or perhaps, I just flash any 118, and that will give me the newest firmware. Then I can flash other ROMs (that use the same firmware), which will have updated modems, and consequently get my network signal back. Is this how it works? Want to be 100% sure before I go flashing with firmware that would make my phone unusable. Thanks for any advice!

it means it has customized local apps like sony jiv , bse/nse stock prices etc . customized means all these local customizations by sony itself. generic unbranded ftf means without such bloatware

Thanks! Well can someone plz post the generic unbranded one. Because there is no convenient way to root 5.1 for locked bootloader. And 95% people hate that bloatware.
Btw I dont think there might be any problem if I installed that on my Indian version of Xperia. Z Ultra C6802

U will only have the Customized IN for India. U can delete those apps from ur app launcher. bdw I had flashed this ftf
Thread closed at OP request for dead links.
So I noticed that sony released official 6.0 for our Z2, in my country we are not even updated to. 264( by ota and sony companion). So I want to update my device to MM via flashtool but all FTFs are for different countries. So I wonder which should I use, I'm afraid different countries fw may not compatible with my device. Since z2 is the very first high end device I own so I cant risk. Or can I just flash one of the ftf and exclude baseband, will that be ok? I have d6503 and a bit knowledge about flashtool
All firmwares are same except bloatwares for different countries. My z2 comes from UK market but I flash Russia FTF and it works perfectly
Ok thx
Could someone please explain why my NEW Xz1 phone (and Sony companion) think that I have the latest updates when according to XperiFirm much newer versions exist. Currently I have:
47.1.A.2.281 currently installed on the phone yet
47.1.A.12.235 is the latest available in other geographical areas.
Is it ok to flash this latest one from a different geographical area onto my phone ?
I live in New Zealand and was considering flashing a UK Customized 47.1.A.12.235
I would use Flashtool by Androxyde.
Would this void my warranty ?
Why is it that Sony put out updates but we just don't get to see them - who's dragging the chain here ?
And since posting the above I'm aware that two more updates have happened:
47.1.A.12.270
47.1.A.16.20
WTF is going on ? Why are we not getting ANY updates ?

You can flash firmware from other region, but you may lose FOTA update pushes, this means you can only upgrade your firmware through Flashtool or other similar tools in the future.
As for the warranty, I have no idea about it, but I have already flashed my Chinese version XZ1 to Malaysian firmware, since the Chinese firmware does not have any Google apps, and it just works fine, I also replaced the oem.sin file from Chinese firmware to Malaysian firmware in order to have VoLTE enabled.
But as I mentioned before, I lose FOTA after flashed my phone, so I have to download the entire firmware via XperiFirm and flash it manually. If you flash the original firmware without modifications, you may not lose FOTA, if you do so, please tell me!
EDIT: You can only flash firmware matches your model, so don't flash a G8342 firmware into a G8341 or other.
Hi!
Is it possible that my software version disappeared and discontinued?! I have a J9110 with Android 10 customized_fr, but now I just saw on xpericheck that this version is no longer available.... It doesn't show up Should I install an other version? Do they really force me to reinstall my whole... Everything? That's ridiculous.
I don't know. Probably. Because XperiCheck doesn't list it too. Install Flashtool 0.9.28.0, download another firmware region like Customized RU or Customized EU and flash it. No any data loss.
How does Xperia Companion react when you connect your phone?
It might show you the update available.
If not just using Flashtool and upgrading to another region is worth it. No data loss during this process.
All the best!
