You may have a partial install like I did(have since restored via odin). If baseband is incremented but build still reads Eclair without the new version after it, then you got partial.
I got a partial update also. Any idea on what got left out?
How do I fix a partial?
I do not how to use Odin to fix.

That will all depend on what part of the upgrade script yours died in. No way to know as from what I have seen nobody even has a copy of the script yet.

Update nougat EVA-L09C25B136

Hello, I have an EVA-L09C25B136 that's on EMUI 4.1 and Android 6.0. When I check for updates there are not any updates.
The phone is from a latin american carrier "Claro DR" and I haven't done anything to the phone, so it is pure stock. Is there any way I can update this phone to the latest available version for this model?
I have searched the forums but the guides are not directly related to my exact build so I want to be sure before I go and damage it.
Thank you.
FirmwareFinder. It can download every available build from Huaweis server..
https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder&hl=en
How do I know which firmware is compatible with my device?
When I get the list and check every one of the options available, none of those say that they are for my build number.
Don't know what you did.
Open FirmwareFinder, normally it'll recognize your build. In your case EVA-L09C25. If not set the model manually.
Then tap the refresh button and the app will show all builds.
Tap on the first one (EVA-L09C25B320) and ckeck firmware access.
A pop-up will appear with following text: "Firmware approved for installation Models ... . So, there's your latest build (with Nougat, EMUI 5).
For further information about FirmwareFinder and how to use it please check the forum or ask google.
Here is what I did:
In firmware finder indeed it recognized my phone as EVA-L09C25.
1) Click the refresh button.
2) First two firmwares said not approved for installation.
3) 3rd on the list: Firmware aproved for installation Models for Installation: VIE-L09C25B320. Shouldn't be EVA-L09?
4) Tried downloading with firmware finder proxy, download stops at 74%, and closes updater.
5) Tried downloading the zip file and extracting the UPDATE.APP and copied it to the root of the SD Card in the dload folder.
6) Started the update on reboot it says that the firmware is not compatible.
What else should I try?
Well, I've seen what you mean. Very strange. I can only assume that it's caused by C25. It's not even listed in the cust list here https://www.huaweiblog.de/firmware-update-was-bedeutet-cust-emui-und-co/ (german).
Sorry, that I don't know more.

Serial Number Change

I created a backup from TWRP tonight and I noticed that the serial number of my phone has changed from ZX1G2***RS to 65***e28. Is this an issue I have to worry about? I have made multiple TWRP backups and the serial number has always been the first serial number. Even when going to Settings > About Phone > Status it now shows the second (new) serial number. I haven't factory reset or wiped the phone in quite a while, I've only installed the monthly security updates.
I have the same problem after updated to the latest 2017.10.06. LineageOS build, i have a new serial number in bootloader, TWRP and in Android itself (ZX1G*****G changed to 9d1****7). I have to reactivate my mobile banking app because of this.
The same thing happened to me after sideloading the October 5, 2017 security update.

Can't Update System Software

I just got brand new Xperia X Performance that came with 6.0.1, and I'm trying to figure out why I can update it. It's unlocked but not rooted, basically right from the factory as far as I know.
When I go into Software Update in the phone's settings, it says "Your device already has the latest available system updates."
When I use the Sony app on my PC it says my system software is up to date.
I actually can't find anything about this issue, anybody here have any ideas?
Thanks!
try downloading and running xperifirm, find out if your region has the update at all, you should be able to update atleast to 7 anyway
There are a few variants that are considered as internal units or something like that and they don't get OTA updates, also HK units were stuck on 7 for some reason last time I checked. Mine is a french model, and yesterday I received the april security patches while the global variant got it two months ago

Here's a screenshot of Xperiafirm. https://ibb.co/dUCN3T
I'm in Canada, though I'm on Freedom Mobile, not Rogers or Bell. I don't think my carrier ever sold this phone, and I'm not sure what would happen if I flashed 8.0 made for Bell or Rogers phones.
Ideally I'd like 7.1.1 Canadian generic for Xperia X Performance, but I can't seem to find that anywhere.
I've also never done this so I don't really know what I'm doing, and don't want to void my warranty!
Thanks for you help!!
Good the ROMs that you see for Canada are all latest 8.0 with May security patches and maybe your phone is one of these and the updates just got stucked for some reason.
First you have to check what kind of model you have to check this, to do so you should open the dialler and type
*#*#7378423#*#*
From the service menu you should select -> Service Info -> Software Info and look for Customization Version:
As I said mine is a french model so it states 1302-9342_R2E your should be something different but only the first 8 numbers matter
then look this number in Xperifirm if yours is everything different from Internal Unit (second column from the screenshot) then there is a easy way to try and update without loosing your warranty
First there is always a risk! But I have done this a few times for my Xperia U and Xperia M5 and had no problems at all.
Do a backup - contacts...everything you need as it will delete them
charge the phone to at least 80%
then you should go to the Xperia Companion and do a software repair, not update but repair
It should install the latest version for your phone but it shows the version it installed only when it's finished...
Even if it has not installed the latest update then just connect the phone to your wifi/LTE and try the OTA updates again (could take up to an hour)
This is the safest way that will not void your warranty in any way but will delete your info (contacts, pics..etc. ) so do a backup prior
And if possible use a laptop with a working battery as even a 1 second glitch in the grid could cause the phone to get bricked
And if your phone is imported from China and the customization number is considered as an Internal Unit the only way you could get 7.0 or 8.0 is by flashing and another ftf file as the ones for Bell Canada or Rogers, there are actually some ROMs uploaded in XperiaBlog
there could be some in XDA but I have not search for any

Thanks so much for the reply...I discovered the version of Android installed on my phone is a version meant for Journalists/Reviewers/Commercial use, and can not be updated. I just got a refund for the 3-year warranty portion of my purchase after pointing this out to them. So after the 90 day warranty that came with it runs out, I'll be able to do anything I feel like with this device.
I'll be looking for a safe way to install 7.1.1 hopefully, and if not then 8.0. There seem to be less issues with 7.1.1, but there's really only one way to find out: when I start using it.
I'll definitely need a point in the right direction when it comes to that though. I understand Sony has an official flashing tool, and you have to unlock the bootloader (which is supported on my phone even with this version). But I haven't done it before and don't know how.

updating to Pie - how to tell / predict / force firmware region

I've got an unrooted xz1c that came with some sort of non-US stock firmware - which I know, because the fingerprint reader works. It's been nagging me to update it to Pie since I bought it, and I'm thinking I'd like to do it via the "official" (OTA) route, since it claims to be able to do it in-place, without having to reinstall apps, restore data, etc. What I want to avoid, though, is ending up with a US update, losing my fingerprint reader, and having to jump through hoops to get it back.
The build number in About Phone says 47.1.A.12.270. Is there some way of determining the current region, and confirming what region the update plans to install (without starting the update) - and/or forcing the region to match what I currently have? My google accounts, phone #, etc. are all US-based, if that makes any difference in terms of the update deciding what region is appropriate.
I was looking at a guide for installing specific region firmware via xperifirm/newflasher, but it indicated that the result would be a wiped phone, and I don't have time to deal with re-configuring everything from scratch right now.
Firmware customization does not change by applying OTA update. It will install the update of the same region that is already installed.

In the past the OTA updates have famously locked thier owners out of thier phones by not regonising the unlock code that has been set, so make sure you disable it before you start.
Also, updating from 8 to 9 leaves some apps glitchy and there have been several reports of phone problems that can only be resolved by a full factory reset.
If you want the best experiance from your phone, wiping it would be the best option when upgrading.
Use Xperia transfer to back up apps/call history/contacts/text history. Then restore once you've wiped your phone.
@meeotch1 If you are happy with Oreo and without the latest security patches and updates, just let the phone OTA update it to the final Oreo version 47.1.A.16.20 and leave it there.
You can force close the Software update app from app settings to make it stop nagging about the update. And with adb you can even disable it permanently (and enable later if you wish to go for Pie).
Thanks for the advice. Good to know that the nag is disableable. So I take it that OTA upgrades *within* major versions (so Oreo 47.1.A.12.270 to 47.1.A.16.20) do not suffer the glitches mentioned by the first reply above?
Also, when I eventually go Pie, what's the least painful / most reliable restore method after wiping the phone? Is the built-in Xperia backup/restore available in Settings good enough? I'd prefer not to upload all my data to Google, unless there's some guarantee that it's encrypted. Don't need the NSA digging through my messages to radical terrorists and international drug lords.
To find out the customization, go to the service menu and select "Software Info".
You'll see an entry named "Customization Version" with a number like "1310-4371_R6C".
You can then look in XperiFirm at the column named "CDA".
On the example I gave, "1310-4371" corresponds in XperiFirm to "Customized US".
You can also look further down in the software info at "Current Modem Config" where the format will be something like:
/system/etc/customization/modem/amss_fsg_lilac_tmobile_us_ims_tar.mbn"
That tells me that my SIM card matched a mobile operator that is recognized as having a valid modem configuration file for my customization's region and, as such, loaded the correct modem file for that operator.
It also shows that I'm using T-Mobile US as my operator (tmobile_us) and I have some kind of VoLTE available (ims).
