Sony z2(L50u) flash android 5 + rom, no baseband,no imei - Xperia Z2 Q&A, Help & Troubleshooting

HI,
I want to upgrade my phone z2(L50u) to android 5+, but I searched its ftf by XperiFirm, and not found any android 5+ firmware to support it. so I used D6802 ftf flashing it and the phone lost baseband and imei.
I have stock ftf which is android 4, if I can transfer the files that related to baseband to new os?
how can I do?
thanks
and now I flashed a new 5.11 rom, it has baseband and imei,but no mobile network signal show top-right, just a right triangle

[Q] what is 2.1.1.A.0.6 or 2.1.1.C.0.0 SE firmware

i was trying to installe android 2.3.5 but i found its post the i cant unless i have
Only 2.1.1.A.0.6 or 2.1.1.C.0.0 SE firmware is that the orignal Rom the device came with ?
If you go into 'settings' then 'about phone' you will see the phones baseband version. If it ends in 15 it is most likely one of the two firmwares you mention. If you try to install a rom dependant on these firmwares and you don't have it you will temporarily brick your phone. (Requiring the use of the Sony Ericcson Update Service to hopefully restore the phone to working order).
It is possible your phone has the firmware already installed but you need to check! Some network providers have been very slow at releasing them. If you manage to find the firmware on the web (make sure it is the correct language and layout for your locale - AND the correct phone) then you need to use a flashing utility to install it, I use 'flashtool' as it can root the phone and install xrecovery, but you must be sure you read the documentation and follow the proceedure.
Once you have xrecovery and the phone is rooted the magic can begin..
Be careful. Its very easy to render your phone bricked (as in the phone is as useful as a brick!). No one here can take responsibility for the advice given or your actions.

my phone android version 2.2.1
baseband version M76XX-TSNCJOLYM-53404015
KERNAL VERSION 2.6.29 [email protected]#1
MOD VERSION FROYO MINICM/CMV6 HYBRID BY SLADE87 AND OWAIN 94
BUILD NUMBER V5.01 FINAL RELEASE
SO CAN I INSTALL SONYBREAD WHICH requires 2.1.1.A.0.6 or 2.1.1.C.0.0 SE firmware
so do i have it????
Not anymore, but if you do Factory reset, yes you have
no it will not cuz the factory ROM is not exsist
In my understanding the firmware doesn't change when you install a custom rom and (to me) they are two different entities. So yes, in my view you should be able to flash sonybread but I haven't used it myself but I have other gingerbread ports without a problem
Once your on the correct baseband you can change between roms without having to flash via the pc/flashtool.
If you get into bootloops then you can try restoring an xrecovery/cwm recovery or failing that reflashing with seus/flashtool.

[Q] About baseband .77 - Brazil

Hi everyone,
Recently, I flashed the stock .587 firmware and made some tweaks in build.prop.
And data is not working now.
(even without tweaks data wasnt working)
Never faced this problem before (except for some custom roms)
I'm on baseband .77 and before flash stock ROM I was on .72
Started to think that baseband .77 IS NOT avaliable in Brazil.
Is this true? Do I need to flash .72 again?
The device is ST15
Already searched but didnt found anything about it.
Thank you...
try to flash stock rom again, in ftf file format using flashtool, not a flashable cwm rom.

Flash stock Indian 4.4.2 ftf and recheck.
Hi,
You mentioned you are rooted , so i assume you have recovery.
Search for the tread for a prerooted LP Firmware zip and flash over your current Firmware.
I did it, and its working great.

Lost IMEI from Korean Version 501SO to E6653

Hello,
i had a Xperia z5 Compact from my dad which was an 501SO in Android 6.0 but it had some issues so i thought it may would help to flash it with flashtool on firmware:
Generic Global 32.3.A.0.376 which is Android 7
After flashing Sim was not working i think its because of the missing IMEI now.
Now i wanted to root it for restoring my IMEI.
First of all i wanted to unlock the Bootloader but my Menu shows that its not Unlockable...
Because of this i wanted to use maybe some tool like Iovyroot but i dont understand the tool or its not running.
If i am running the adb.exe a console just runns through?
Currently the phone is running on the Android 7 Generic Global 32.3.A.0.376 firmware.
How can i root it now? Do i need to flash it back to Android 6 or 5 for an temporary root?

Question Flashing newer firmware on an unrooted XQ-CQ54

Hi all,
I wanted to flash a newer android 13 stock firmware because my Sony from a UK operator doesn't get the OTA update.
I have the firmware from XperiFirm and made the ftf with flashtool. Just before I was about to get if flashed I was reading comment saying this tool is not good anymore, but I am not 100% sure how to use the Newflasher instead.
Could someone help me on that?
I don't really want to brick my phone and if it's not a safe way to get android 13 I might just don't do it.
Cheers.
