Sorry to tell you I havent. Same say you can brick the Phone by installing another firmware others says that nothing will happen because the hardware is different meaning this Phone cant recieve the bands that is not suppose to. I dont know. I've read other sites seraching for a solution to this problem with no luck. I guess we have to wait till a custom rom that works.

The model you buy works best in the region it's bought in. Some networks will cross-over when in a different continent, but not all, usually. You can't add frequencies to the phone whenever you want, as far as I know.

I have installed a e2303 software on a e2306 phone and it works fine, but still has the e2306 bands.
Maybe in the future there is a way...

Similar Issue
I have a similar problem so I thought to post here.
I have a I5500L.
It came with this firmware out of the box I5500LUYJP9 (2.2) it was locked to Movistar (Venezuela).
I unlocked it with SRS to use it with my carrier (Digitel Venezuela).
No matter what I try, I cannot make it work with 3G, only EDGE.
I've tried many things, changing bands, forcing WCDMA, and a lot of tricks found on this and other forums, but nothing works.
It's not that it doesn't work with 3G and goes to EDGE, but that te phone is only working on basic GSM, and cannot connect to the network if I change any setting.
Funny thing is my wife has an I5500 (without the L), it was bought unlocked, it came with some European Firmware, and hers works perfectly with 3G.
She has the same carrier as me.
Another thing to note is, my phone detects a network called "Digitel", her phone detects a network called "DIGITEL-GSM".
¿What could be the problem?
¿Could I flash some European firmware to my phone to make this work?
¿Will this affect the SIM unlock?
Thanks.

Thanks.
What are the implications or possible sideffects of changing the baseband?
I mean if a baseband won't work, there should be another one that does right?
I'll be doing some reading, but a head's up wouldn't hurt.

there no danger in changing basebands, the only thing is, some will, and some wont work. you should just try the baseband from wherever you are 1st, but if that doesnt work, try another. doesnt matter if you are from UK and you use an american baseband, if it works, its completely fine
has it worked?

Repair my bands xperia go

hello:
I purchased a sony xperia Go which works for me so good, but the only problem is that the firmware st27i brought it only works with two bands hsdupa. In my country only works with the band 850 and not raise my smarthphone hsdupa signal. May indicate someone here or help me get or install firmware for xperia st27a go?.
regards
Firmware won't help here, it's a hardware issue.
But is no hardware problem, the bands are locked by the version of european software

You can't. That phone uses different bands then the US. You will have to get a world phone.

"World phone", also known as a quad band phone. If you want an unlocked phone to work on T-Mobile's LTE, it'll need to support band 4.

Well, I don't think there's nothing much you can do with your phones as the US mobile network operated at different band and your device may not be supporting that band better option for you would be getting a new phone form the vendor other than this no other option can help you much with the problem you are currently experiencing.
Hi. :laugh: today my problem is solved, i can use 3g network all time, thanks all everyboby , so happy :laugh::laugh::laugh:

(Need Help) Sony Xperia 1 SOV40 Flash into J8110 (but does not have voLTE in Malaysia)

I tried to flash Sony Xperia 1 SOV40 into J8110 Global Rom, but does not have voLTE available for Malaysia
Someone told that can mix SEA version sin with Global Version sin, i have tried to move the modem.sin (All three from J9110 SEA version) into the J8110 but still not working
seeking for any advice to make voLTE work
Thanks and appreciated
You can try Customized JP OEMs.
Don't need to do the modems Just flash the OEMs only.
It will definitely work.
I have J91110 and it worked for me.
If you already have the files than thats fine.
If NOT you start it with the XperiFIrm and start download. When it says downloading 3 of 3 then stop downloading.
Open Flashtool and Use Files Decrypt to extract the OEMs.
Just flash anything with the name OEM using newflasher.

ok understand, thanks for that, i am still figuring out why umobile malaysia voLTE not working
@Jamestan1015 hi bro
how do you do to get hd calls. I am also a malaysian. Satisfied I was looking for a way to get volte but failed. do you use global rom 11 or still on android 10
for me i like use firmware from softbank smooth compare to global rom 11

even VoLTE feature is available. As I know, Umobile and Yes4G may not work excepts other sims. If only your Xperia 1 is from Au/Softbank set.

Malaysian here, which global ROM your guy using? I try all j8110 ROM + OEM still can't get the volte
Interesting, I've tried flashing OEM files from customized JP/SEA/UK into my J8110 variant, but still can't get VOLTE working, I tried flashing JP oem files, all it gave me is a corrupted bootloader, (I figured it may have been caused by flashing 3 different firmwares onto my device) , My last option is to factory reset it.
Thanks for this, I have an Xperia 1 AU KDDI Japan SOV40 flashed with J8110 UK Firmware, and flashed Customized Japan OEM for volte, now volte working, by the way I'm from the Philippines and I use DITO Telecommunity SIM which they don't have 2G and 3G Networks, only 4G and 5G that's why to use calls you need VOLTE Enabled on your device.

Where did you get OEM from? Still try a solution how to make it work but still haven't found any better steps to do since I'm afraid of bootloop or something else.
Now I see that 5G are officially announced before, a lot of telcos had to discontinued 2G and 3G networks. 2G network in Malaysia will stop working soon. Not sure when it is.

I just installed Customized JP OEM by following on the first page's instruction before I formatted my phone. But nothing changed. After that, I tried formatting my phone without flashing oem but the result shows nothing about VoLTE. So, I just keep using it without VoLTE function because I don't wanna take a risk to install it again due to afraid of having a bootloop if I feel hesitated to make it work.
But, I will try to find another way to fix that problem soon if I got one.
I recently buy Xperia 1 SOV40 single sim. Seller say that Umobile and YES doesn't work in this model. I try insert Umobile sim and can be use to call and internet. I not sure about VoLTE. Do I need to flash any firmware to make sure Umobile get VoLTE? Or SOV40 not support Umobile VoLTE frequency?
Please help me with Volte,
Really need it
