[Q] No Network - Sony Xperia S, Acro S, Ion

Hi everyone. My friend and I tried to flash a custom rom to his Xperia S. so before that we have to root, install recovery and etc.
we succeed on flash everything but that's what we thought. We noticed that the phone doesn't have any network, tried different sim and both from different networks are useless. So we Read and we still can't find any solution.
the phone IMEI is intact
the phone is sim unlocked
the baseband is 8660-AAAABQOLYM-313065-39
the phone is on .96 FTF
we already tried to revert back to .96 FTFs I think the baseband is not compatible with our country Philippines.
we already tried downloading the .96 customized PH FTF from Xperiafirm but still there's no luck.
we already tried repairing through PC companion
we already tried flashing FTFs .200 .211 and.96
Can you help us?

Did You flash a stock firmware using flashtool version 0.9.19.1? It causes sim lock while flashing. It was brought to attention when same problem was aced by other user. Quoting him below.

Tried many stock FW and found the reason of the recent problem happened to many people all over the world. That's flashtool-0.9.19.1 which contained some script errors which lead to bootloader locking and loose of network connection

thanks for the immediate reply. What should we do then? just flash a stock FTF using flashtool with different version from the ones you stated? or we can still use the 0.9.19.1 but we have to exclude the simlock?

No network

That's no use bro. I've tried many Stock FW as well as many versions of Flashtool after getting same problem with my phone. As Flashtool creator wrote "The only way to recover from locked phones is to reactivate them in a service center or to restore the 07DA unit". So, if you don't have TA partition backup made prior bootloader unlocking then you've got an alarm with camera & mp3 player made by Sony. The ASC propose to replace the whole motherboard.

No Connection To Network After Update

Hi Frineds,
Sorry for my poor English.. I have a very strange problem after updating new firmaware on my Arc. When i flash new firmaware, my phone doesn't connect to network. I get an error that "sim card preventing to connect with network". I have tried everything but always get this error with new firmaware. Therefore i am still on .145. I have unlocked bootloader, so i use FlashTool. I have tried Global Generic & Nordic versions of new firmaware.
Am i the only one having this problem? Can someone think of any possible reason for that? Any idea?
+1 I am Spanish and I have a Vodafone mobile
Does anyone know any possible reason? Any suggestion, please?
I updated my bro's Arc with FlashTool & he has not any problem with network.. I used my sim card in his Arc & it worked like a charm. What's wrong with my Arc?

Are you preserving your data on flashing? If so that might be the reason.

No, data wiped But Thanks Harfot you tried to help me out
I was also having trouble with flashing as follows,
After flashing (not wiping user data) generic 4.0.A.2.368 followed by DooMKernel v02 the hole lot was working - not very well but working. Problem was I was not able to install neither BusyBox nor APP2SD.
This was followed by 2 more tries flashing but it never worked but I was shure it could work.
So I flashed the original 3.0.A.2.181, used GingerBreak to root and installed BusyBox. It worked.
Then I again flashed generic 4.0.A.2.368 followed by actual DooMKernel. It worked and BusyBox was still working. Then I installed APP2SD and on reboot that part worked also. At last I restored my user apps with Titanium and the were all moved to the new ext3 partion on the SD card.
Later I have flashed the latest two DooMKernels without any problems.
It might be worth for you to try reflashing.
Reflashing the firmware should solve your problem.
Thanks Harfot & Xtacy! i have actually reflashed my phone multiple times.
1) First Global Generic with FlashTool..
2) Tried Again Global Generic with Flashtool (Without Sim Card in Mobile)
3) Tried WotanServer & flashed Nordic version..
4) Re-locked bootloader & flashed again Global Generic
5) Flashed Nordic Telia version
6) Re-locked bootloader again & changed customization number to Telia Sweden & flashed through SEUS
7) Falshed UK Generic
And result is the same: No network connection
Do you have the possibility to try with another SIM card?
I relocked bootloader today & flashed phone through SEUS first. When i started phone, i got network connection but after just 5 minutes disconnected again & nothing helped. I repaired phone with PC Companion but result is the same..
When i say network connection, i mean GSM Connection.. I can't get GSM connection & therefore can't call someone or send sms..
@Harfot: First i used my SIM in my bro's Arc which is on newest firmaware, I got GSM connection on his Arc with my Sim card.. (Nothing wrong with my sim?)
Then i used his sim card (it was from another operator) in my flashed Arc (on .368) & didn't get any problem, got GSM connection :-/ Now i am confused. My sim card & my phone don't like each other or what?

Well, now I am puzzled too.
Try cleaning contacts in phone and suface of sim (no liquid). Try pressing sim card firmly when booting phone.
The solution for me was to change the SIM
@Harfot: Thanks, I'll try again tonight & will follow your suggestion
@neoduende: Thanks, I have actually ordered my service provider to send a new sim card

Simlock

Really don't know exactly what it does, but generally you don't include this file when you bundle a rom with flashtool, so no harm.

how do i unlock it? That's the whole point of me posting about this.
After i unlock my bootloader, i face this issue. but flashing finished successfully. Sometime it may be a DRM key related item.
Dont flash that file. its simlock data and if you flash it on a phone with different imei then you will kill the phone without any way other than sony service center to fix it.
Don't worry about that, i always get that warning and there was no problem.

I've read this 'simlock.ta' thread with some interest because I have a similar issue myself.. Might you have any suggestions?
In short, my Xperia (Ray) refuses to read my SIM card. In fact, it doesn't even ask me for my PIN number, it just boots as normal but I have no connection to any network. I've tried using the SIM card in another phone and it works fine, therefore the problem is with the phone itself.
I'd recently had my phone network & bootloader unlocked by wotanserver using the test point method - because of this I thought the DRM keys would be fine (e.g. TrackId & Timescape still worked). However, when I was updating from GB .42 to .62 OTA (to flash a GB ROM) my phone bricked! So, I ended up using s1tool to restore the locked bootloader. Then I used flashtool to flash a stock ICS ftf file. It seemed to work (the phone rebooted) but it was then I noticed that the SIM card wasn't being recognised. Also, in the Flashtool log I noticed that a blue line was there saying 'this file is ignored simlock.ta'.
Hard resets & updating with Sony Update Service isn't working and I'm really confused at this stage.
Is my phone screwed for good?

Did you find a solution for your problem?
In reality, I have the same problem with an xperia j (ST26i) , with some differences:
Initial Problem:
- The mobile belongs to my cousin, she updated it with the sony update center to the latest version (JB 4.1.2) and there: problem with the wifi when the sim.
- I got the mobile, and downgrade to the 4.0.4 version, I've tried 4 different versions:
-> ST26i_11.0.A.3.18_Global
-> ST26i_11.0.A.7.5_CE
-> ST26i_11.0.A.3.28_WE
-> St26i_4.0.4_11.0.A.3.28_CE3
I had always the problem with the wifi when the sim plugged.
Finally I've tried also the UNOFFICIAL CM 10, with no success
- I found a solution with the apk wifix manager witch worked with the 28 WE version of the firmware.
But I've continued to search an other solution, and I've remarked that when I flash the rom I always get the Warn: "This file is ignored : simlock.ta "
After some research I get an advice by a member of XDA to rename the file as "preset.ta", AND THERE, it works no warning ... BUT the sim is blocked (not locked) and I have always the message (invalid card).
I've tried to reflash the firmware many times, to relock the bootloader (with appropriate ftf proposed in this forum ), Tried to use the sony update service .. But I have always the same problem (INVALID CARD)
I've also tried to format everything with CWM (system,card,cache) and made a sdcard partition, and NO way.
So, can any body help me with that please?!
Note : I'm in the middle east zone, some suggestions in the web talk about re-installing the official O2 rom, but I've searched this ROM with no success.

[Q] a couple questions before flashing arc...

I'm planing on flashing my arc, but I've a few questions first.
the method I'm using is via wotan because I heard is the easiest one (I know i've to paid, but is just 1.99 euro).
I have a xperia arc lt15a 2.3.4 firmware .62, directly from my carrier, ICS hasn't been out for my country yet, I want to flash to the Generic Trade US (4.0.4) (LT15a) once that I flash to that version via wotan it will be compatible with my carrier?? my carrier is from central america and my bootloaders are locked and I dont want to "lock" my phone. I dont care if I will still be only compatible with my carrier, but I just want to make sure that I would still be able to make and receive calls...
another question is: if I dont like it ( ICS ), can I go back using PCC?? or from now on I just have to use tools like flashtool or wotan to change version??????
You can flash 4.0.4 with flashtool, it's free.
And no , after you flash ics you can't go back to gb by pc companion , because your phone will be debranded, so pc companion will say that you have the latest firmware in your phone.
You can get back to gb , by flashing a gb rom by flashtool or using wotanserver.
but by flashing via wotan or flashtool it will not lock my phone and make it unable to detect my carrier (make calls, sms, etc..)??? because this happen to me once with my iphone that the jailbreak update the baseband and got myself a very expensive ipod

Flash H3113 firmware onto XA2 (Dual Sim) H4113

Hi,
Its been some time since I did any flashing so apologies if this is a simple ask.
I have a H4113 XA2 dual Sim, I want to know if it is possible to flash the single sim H3113 equivalent firmware onto my phone because current firmware does not support VOWIFI etc. My network suppliers H3113 firmware does.
If so how do I do it in Flashtool as it currently tells me incompatible if I try the whole ftf.
Thanks in advance

Hi
I don't think it's possible, you will get lots of problems due to compatibility... I advise you to use Magisk instead to put VoWiFi and other features.
Regards,
F.
It is possible change stock firmware whole one platform for XA2 it is "Nile". I flash stock rom "Discavery"(XA2 ultra) to "Pioneer"(regular XA2) they r both Nile-platform.
Other people flash stock-roms btwin regions, to unlock some 4G-bands, for example.
But, u have to know:
"Simlock.ta" (maybe all *.ta files, as usual i delete all of em from firmware folder)& "persist.sin" - are dangerous parts of stock-roms. Don't flash they r btwin different models!!! Bcoz of that *.ftf roms r dangerous variant(coz they contain this parts).
I use "xperifirm" to download firmware by *.sin-files, then delete *.ta and persist, after that flash by "newflasher".

[GUIDE] Flashing XQ-AT51 Firmware on XQ-AT52 Device

Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.
MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW
Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.
Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware
Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.
Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!
Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.
Step 3 : Open newflasher.exe
Step 4: type n then press enter
Step 5: type n again and press enter
Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.
Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.
At this point you should have a fully working AT51 firmware!
Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.

Can you please help? I followed and i got a corrupted message and power off in 5 second.
I tried xperia companion, failed.
I tried to reflash newflasher with original firmware again, failed.

Can you tell me the model of your xperia phone? If you can still get it into flash mode when the notification LED turns green you may still be able to recover it.
Hi, I finally managed to restore it. I have to remove all the ta files to flash it, then it booted up.
Thanks for your respond.

I have using newflasher
After using 3 time xperia companion it work normal again
Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.
https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.
Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully
edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly
Would it work to unlock my phone
Thanks for the guide!
Can I ask few questions please?
First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.
And the second one is could this flash unlock my phone?
I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.
I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.
So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.
I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..
Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

You do not need the bootloader unlocked as you are flashing official firmware.
Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
Sent from my XQ-AT52 using Tapatalk
I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.
So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all. But I'm still unable to flash to the US version without the "Your device is corrupt It can't be trusted and will not boot" error that seems to happen every single time I try to install the US firmware.
Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?

The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.
What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.

I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.

im in the us and was looking to the 256gb version (i think its taiwan). is the hong kong or taiwan version missing anything? or is the only reason to flash to US to get better coverage with us carriers?

It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.
it arrived on 10 still, but its bugging me to update.

This isn't the case now since the US models have Android 11 too now
Can anyone confirm that this process has to be done using USB 2.x? I've read in a separate post that newflasher isn't compatible with USB 3.x, which is currently what all my computer use. Also, should I be using the newest version newflasher?
EDIT: Tried on USB 2.0 and it worked perfectly.
