[F8331] Change stock firmware for a better LTE signal - Sony Xperia XZ Guides, News, & Discussion

Hi everybody,
I'm new here, I have bought my first sony (used) but I notice that the LTE signal is so poor specially indoor. The seller hasn't saw me that the firmware is an UK fw also I live in italy, infact, after a little research, I noticed that there is a carrier's app called EE and the fw version installed is of EE carrier's. The phone is sim unlock. There isn't root and I haven't unlook the bootloader.
My questions are:
- Can I change the stock uk firmware putting in an Italian stock firmware?
- Can I change it without root and without unlook the bootloader?
- How?
- Is there a guide that I can follow?
- Can I change the CSC for preserve the ota upgrade? How? I'd like to change fw preserving OTA update.
I don't wanna unlock the bootloader and root the phone cause I don't want lose the DRM licenses (widevine specially). I'm not interested to rooting or make any modding.
I'd like to put a stock room without bloat apps and with a strong lte signal.
Here the Info about the phone:

I think it should be possible to just Flash another Regions Firmware via Androxydes Flashtool.
No need for unlock as long as u have any offical fw (XperiFirm comes with Flashtool and downloads offical files)
But I may be wrong tho, this just came to my mind in the first moment

Thanks you LoaderFabi for the suggest, so I will waiting for a confirmation about that.
Meanwhile can y tell me a link to a guide and download the tool?
Anyway, thanks again ?

You can flash any region's firmware without unlocking the bootloader. You need Xperifirm to download the firmware, and Flashtool to flash it.

Ok, and about the OTA's update? Will it be automatically? Or do I have something about? And how?
Can you link me a guide to flash the fw and, eventually, to do something about OTA's update?
Thanks

Since it's an official firmware, you always get updates OTA (i think XZ will no longer get updates but no need to worry). I didn't see any guide to flash, i'll probably today write a guide to flash firmwares.

Thanks y so much Kuarinfou, I will waiting for your guide. I don't remember where I red in this forum about the CSC and that it could not change also flashing a stock fw bringing the OTA's issue... Probably I remember wrong ?
Anyway, Quote me when you will do it.

[Firmware] P7300ZFKK1 (Android 3.2)

A new firmware tweeted by @Samfirmware
FIRMWARE: P7300ZFKK1_P7300ZFKK1_OZF Online! (Android 3.2)

Enjoy!
Awesome! Thanks!
Don't know if you know the answer to this or not, but if you do, perhaps you can answer/confirm a couple of things:
1. What region is this update for? Or is it multi-CSC?
2a. I notice the presence of a .pit file, so I'm assuming that this is a full wipe update. Correct?
2b. Couldn't I just flash the new modem and firmware packages without the bootloader and partition files without issue/wipe?
3. New bootloader... How locked down is that? Can I flash without it? Will I still be able to use CWM recovery?
Thanks in advance!
Looks like a chinese FW, according to some translated pages in Google.
Well I guess that sorta answers part 1...
I suppose it may just be prudent to remain patient and wait for an official multi-CSC/region build.
I try this rom but there are no multi csc, only English and chinese keyboard. And there are a lot of chinese apps.
But she seems faster than the orange rom.

[Q] N9005 Lollipop stock rom. Does it matter if...

I have an N9005 model Note 3, now I bought this second hand from eBay, and it is unlocked. Though it still shows an O2 boot up animation, so I'm guessing it was unlocked from O2?.. My question here is, I've noticed on Sammobile that there are now some Lollopop firmware updates available for my device, however, I don't see any unbranded version for the United Kingdom, only Vodafone? So if I flash this, will it have any repercussions on device operability, such as losing unlock (I am on Three UK sim card), or does it just mean that I will have vodafone branding?
EDIT: Sorry, mods please move into correct section.

1. Install this APP for know your CSC better. Maybe your device changed of CSC coz was unlocked.
2. Flash the latest android 4.4.2 UK unbranded if your CSC is BTU: HERE. Wait for the lollipop update.
It is O2U?

1. Yeah and you have the correct firmware if you see the boot animation of O2.
2. Don't flash other different STOCK roms that aren't this ONES if your device works ok.
3. The latest firmware for your device is N9005XXUGNG1.
4. Wait for lollipop stock update via OTA or taking a look sometimes the step 2 (you will have to use ODIN then)
5. Enjoy

In theory NO. But all depends what method they/you used for unlock your device :highfive: (normally they unlock it by IMEI and you have your device unlocked forever)

Okay, great. So, I should definitely wait for O2U? I can't flash Vodafone? Could I flash a BTU when it arrives? Or is it just a definite O2U?

Better wait for O2U updates for avoid problems (No wifi, IMEI null, no data, can't make or receive calls, bootloops, etc) but the phone is yours. You can flash what you want :highfive:

Help please

I've been willing to change rom for a while now but after digging a little, I haven't found anyone with the same build number of mine.
Also it says my system is the latest version and I cannot update.

it strange that your system doesn't show any update. You should be on 232 now (android 6.0). YOu can try to manually flash the complete rom through sptool or update manually one by one using the inbuilt updater.

Your ROM is intended for a specific Telco and more likely you will not receive any update unless your Telco will release the update. If you click system update it will always say it's the latest version. Same case with me here but I already updated to S232. Normally warranty will not be void if you flash using stock ROM. But if you unlock the bootloader the warranty will be void.

I followed the instruction from this post.
[LP][MM] Lenovo K4 Note STOCK Roms (S152) (S232 volte) by anshubham
- Since it was my first time to flash K4 Note, I flashed it with S152 from S102 without unlocking bootloader to preserve the warranty. Of course the FW became generic instead of the original with operator name in it. After I got S152 , I updated it via OTA, a series of updates until I got S232. I hope this helps.

Flashing U Firmware

Hi,
I was wondering if there is a way to go from the P Sprint firmware to U firmware. I want to be able to root my device on QL1. The guide on the forum is for U firmware, but I attempted with my stock Sprint firmware and the only thing I couldn't get to work was mobile data, as APN settings are not adjustable on stock firmware. Is there a way to flash U firmware if I am on stock P?
Thanks,
csmyka

It is possible if your bootloader version is lower than 5, firmware for unlocked version have latest bootloader revision 4. Sprint updates bootloader just to remove this possibility of crossflashing. You are on QL1 version so is not possible at the moment

I have upgraded to RA1 since I posted. Does this still make it impossible?

RA1 is still on 4. If you look at past firmware info, this should be sorted out when Oreo drops.

Phone not updated since March security patch

My F5321 from Malaysia isn't receiving any of the new updates. Last one was 34.4.A.2.32.
Could anyone explain why?
You can check xpericheck.com if there's a newer version,but there's a good chance there isn't one. I'm stuck on 34.4.A.2.50 on the Central Europe version for example, the newest one is .85

Customised MY isn't even listed. :/
What now? Unlocking bootloader if you want latest security patches?
Is there another firmware variant that would be suitable for your location? There may be less difference between the variants than you might expect.

Can you just flash the firmware straight from xperifirm, or do you need an unlocked bootloader or sth?

According to xpericheck, singapore region firmware is also stuck in March. I guess both MY and SG are using the sme FW. I think you cn flsh other region FW without unlocking Bootloader.
Is there a way to flash security updates only, without upgrading to oreo?

I'm in USA, and I've flashed f'd from at least 10 different countries and never seen any affect on the phone operation.

If you want to retain the fingerprint sensor operation, don't flash to US. People here have in the past recommended either DE or UK, as they tend to be updated promptly. No unlocking of bootloader needed.
Okay guys. I'm ready to flash a new firmware, probably Customised UK. Is the guide on xperiablog up to date and accurate? Also, there is a flashtool by Androxyde on flashtool dot net, but there is also a flashtool on Sony Developer World. Which one should I use?
There is only one xperifirm so that's unambiguous, at least.
Edit: also, it doesn't affect user data or the OS in general, does it?
I can only speak from personal experience with the Androxyde flashtool. I've never tried (nor even known about) the Sony flash tool. In my experience, if you don't make any changes to the default settings, the existing user data is carried over into the newly installed firmware. I'm assuming here that you're flashing from one variant of Android 8.0 to another, not from Android 7 to 8, etc.
BTW, I would always advise backing up your data first, of course. If, for some reason, you are dissatisfied with the result, you can normally get a factory installation of your currently-installed firmware by using software restore from SONY (as part of Xperia Companion).
@pseudonym58 Thanks. Is the guide on Xperia blog the one to follow or is there a better one out there?
I don't recall which guide I used. It basically runs like this:
Run Xperiafirm from within flashtool; it will refresh available software. Choose particular phone model and download desired firmware. Back in flashtool proper, connect phone in flash mode. Select downloaded firmware, which is unpacked and prepared for flashing. As I mentioned above, you should not need to make any configuration changes to the default. Flashing can now begin (it might seem to pause temporarily from time to time but don't cancel process).
Don't worry about warnings of missing elements; I have never had a flashing procedure fail as a result of a claimed missing component.
This is just a general procedure; perhaps someone else can recommend the best full tutorial.
Ok so CE1 got the newest (.107) update right now so it can probably be used too.
