I bought a second hand Xperia 1 iii A101so in Pakistan. The phone has serious network connectivity issues after updating to Android 12 lastest update the phone even stops to connect to carrier. I just tried many solution but no improvement. Being a novice i planned to update it with global ROM as mostly on internet people were getting rid of signal issues with flashing Global FW. Not knowing the global ROM are desinged for Dual SIMs, I just updated my A101So with XQ-BC52 using newflasher tool and it worked. After installation there was no connectivity and even no signal was discovered by my phone. I searched again and found that global FW only works on dual model. Then i thought of flashing it again to go back to A101SO but phone is not flashing and showing "Device is Corrupted and Cannot Be Trusted Error" . I tried repairing with Xperia companion but it did not workout. Now i flashed Global XQ-BC52 agan and it working again. I need following help:
1) how can i downgrade my xperia 1-iii to Android 12 with its original stock A101so ROM ?
2) how can i resolve the singal issues on A101SO? can i patch gobal mdem files to A101So to get rid of signal issues?
Currently XQ-BC52 global FW is running on my device with no mobile connectivity. expect that the phone is showing full functionality.
Looking forward to help in this regards

Better not to buy was after Android 13 update it stopped to detect the network signals.
Which model of Xperia 1 III is safe to buy in Pak ? And some models have very less PTA tax right ?

I think mostly are importing A101SO from Japan the bad thing about them is that they bootloader are hardlocked. you cant even intall a custom rom there. better not to risk any money.

Guys i bought My xperia sola one two months ago frm ebay...i started facing network problems for a last few weeks..i tried downgrading to GB and tried latest version of firmware available for my phone too...bt the problem still persists...when i checked its SI number i came to know that its imported from singapore (that could explain network dropping off frequently) and sony gives no support for out of country phones...
Can rooting my device actually relieve me of this problem?..

I've got a Z5 Compact (E5803). My AT&T SIM works perfectly fine with it. I tried the E5823 Customized UK firmware (1298-5497 - 32.2.A.0.305_R13C) and the fingerprint works but the AT&T SIM does not. If the phone is on and I insert or eject the SIM it registers and reboots the phone. But otherwise it does not see the SIM. It keeps saying insert SIM.
I could try firmware after firmware but I thought it might be faster to ask here. I just want to use it with my AT&T SIM and have fingerprint working.
Maybe one of the other E5803 firmwares? I'm gonna trying Customized GEL until I hear from others..

Yes, due to legal issues Sony intentionally disabled the fingerprint scanner in the USA firmware version. The fingerprint scanner is physically there though so if you flash another FW it may work. However I am currently having difficulty getting my SIM card to be recognized when I flash to the newest UK version of the E8523

I also have a US version of the phone (E5803) and also wanted to enable the fingerprint scanner. When I loaded the latest UK version (which is E5823), my SIM (Canadian) was not detected. Bluetooth would also continuously toggle off and on. I'd never tried loading firmware from the other model before, so I just assumed E5803 and E5823 couldn't be mixed. If the AU version works for you, I guess the limitation isn't necessarily the phone model.
Previously I was running Android 6 from the Customized SG (Singapore), and now Android 7 from Customized MY (Malaysia), and both seem to work fine.
The AU version ended up working for me and I haven't looked back since
my e5803 fingerprint scanner works perfect on 7
I have a similar question: just got a Z5c E8523 but using it in the US with AT&T - which firmware should I be using? Customized UK, Customized AUS? Do I still need to flash the MODEM and BASEBAND portions from a US firmware?
Thanks!
If your model number is E5823, the fingerprint sensor should work without any modification. If it is E5803, you'll have to compile or flash a E5823 with any firmware except US. In my personal experience, the AU firmware typically receives firmware updates the fastest.

Okay, so I can't get it to work. I spent all morning trying to get Flashtool to work.
I am trying to flash E5823_32.2.A.5.11_Australia_Generic on my E5803. Each time I get a ERROR - Can't read a byte value.
I initially tried the latest version of Flashtool 0.9.23.2. Then I tried 0.9.18.6 where bricked the device. I then tried 0.9.22.2. Still no luck. I had to re-flash the Customized US version that came with the phone (E5803_32.2.A.5.11_1298-3109).
Should I try flashing the Customized UK version first then try the AU version? Very annoying tbh
Wow, got there in the end (only took me half the day).
After the successful flash of E5803_32.2.A.5.11_1298-3109 after bricking the phone, I tried to flash Customized AU 32.3.A.0.376 / R2D . That one also bricked the phone due to the old version of Flashtool I was using (0.9.22.2). I then tried to flash E5823_32.2.A.5.11_Australia_Generic which now worked.
The main reason I wanted the AU version was for the Baseband... Turns out it was the same lol
you should be able to keep the same modem settings, and the phone should be able to switch configurations when it detects the appropriate bands... provided your carrier is operating at those frequencies.

Don't you have to do something like make the phone think it's a E5823 in build prop first?
Hi there, I recently bought an Z5C (E5803) that was on android 6.1 marshmallow and was Customized Movistar EC, wich is one of my country´s carrier, so 7.0 OTA is long long wait to come.
Long story sort, I used Xperifirm and got 32.3.A.0.376 Customized US for the E5803, flashed and the fingerprint sensor was gone. So I read a little and find out that in US there is no Fingerprint suport for del Z5C.
Then I flashed 32.3.A.0.376 Customized GEL for E5803 and bingo!! Fingerprint sensor worked again.
I don´t think you have to change the firmware for another model for the fingerprint sensor to work.
Hope this help.
hi,
I dont know why i having this network issue.
I flashed lineage os8.1 on my phone and my sim isn't getting any signals. Yep o tried to wait for more than 2 hours, yep i tried different locations, yep my sim is working on other devices, yep i tried to put a different sim but all that didn't work. Mind you my wifi, gps, Bluetooth etc all are working. I tried to flash modem 1 and 2 with non-hlos etc but that didn't work either. So decided to flash stock firmware. Mind you i was on December security patch 2017, meaning having bootloader version 91.08. But since indian firmware flash file is 6.0.1, it won't be compatible, as the bootloader version cant be downgraded. So to get stock firmware back and running i decided to flash RETUS retail version. That firmware did have bootloader v91.08. But unfortunately, I'm getting bootloader remote failure errors, and phone gets into a bootloop. Then i decided to flash RETCN firmware. That did work, my phone is up and running but then again that my sim isn't showing ant signals. I tried with different sims. and dont know what to do.
Oh and one more thing, my imei is visible.
Please help me with this weird sim signal issue.

Definitely you have flashed other region firmware with its own NON-HLOS.bi. so the solution is this that you have to flashed your own region firmware according to your bootloader version.

Yes my brother I also having the same problem. My device is also retin and I also had flash the same retus firmware in my device. Because there is no firmware available for India. The thing is go to the authorised Moto service centre and asked them to update your phone. Do not say about baseband ,even if you say they are going to do but they don't know what is baseband, so they will deny that bootloader is unlocked. Or wait for the Oreo update. It will fix up everything because it comes with everything updated. Only and only if you have retin software channel. But by the way can you tell me your baseband version."it is important to know for me and for you". You can check it out by seeing in about phone.

The only thing which will work here is FLASH ANY CUSTOM ROM because no one can fix your problem. Not even Motorola.
And you will be surprised that I am the only one who solved this problem with stock rom. And dude it took a whole month.

Hello, I'm from Indonesia
Here I found a bug on my device (Sony Xperia xz1 (G8341)). The bug is a little strange
Because it happens in a certain simcard I hope there will be a solution but maybe now I can only hope.
I use two simcards in turn. Simcard A runs normally, there are no problems, but once I switch to Simcard B, there are problems such as being unable to make calls, sending messages and cannot connect with Internet Though the internet is the most important
I did a trial by changing custom ROM starting from LineargeOS 17.1, CarbonOS, LineargeOS 16 and a few more. but the problem persists and in the same thing too
I try to go back to Stock SOV36 (9.0 Pie tail s126) Sony Xperia xz1 (single) .
sure enough the simcard that had problems returned to normal
I use Custom Rom again and yes the problem arises again and again
I checked * # * # 4636 # * # * it turns out the missing IMEI changed 000000 I tried another Simcard IMEI appeared I tried another IMEI Simcard to appear again
BUG only occurs in special simcards that only receive signals 4G Only and use the CAT40 frequency and for other simcards that can accept all types of 4G, 3G and 2G frequencies there is no problem.
For me and some friends who have experienced this problem on the Sony Xperia xz1 (G8341) and the Sony xperia xz1 series. can only wait for the resolution of this problem For me and some friends who have experienced this problem on the Sony Xperia xz1 (G8341) and the Sony xperia xz1 series. can only wait for the resolution of this problem

@starvirus10, that's interesting. Is the phone the SOV36 model?
If so, it is obvious that running fw built for different yoshino model could cause problems.
I wonder - did your SOV36 come with unlockable bootloader?
Just asking because they are folks with SOV36 that are not allowed to do BL unlock.

I think so, but when I bought this Smartphone the software used a Global version . I just recently changed to SOV36
hmmm ... Bootloader Status: yes when I check open No like most bootloader defaults in stock ROM

Sometimes when doing a custom flash. Some things might disappear and make the phone not work properly. I myself made a headache because of that ?
Actually, to improve diag in the forum there has been discussion. we just need to search with the right keywords
@starvirus10, accessing diag port is one thing, not that interesting.
but how is the imei recovery done via the diag port then?

G8341 is single Sim，How to use dual Simcard？
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.

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.

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
