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

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?

Same Problem with Xperia J

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.

I have this error on XPERIA SP C5303 trying to flash 12.0.A.1.284 on top of 12.0.A.1.257. But my phone is SIM Locked and I know it. And I thought that rewriting simlock.ta from unlocked firmware unlock the phone as well. But flashtool skipping that file. It's really annoying !!! Don't know what to do to unlock it now

You should be happy it isn't flashing. FLASHING SOMEONE ELSE'S TA MAY HARD-BRICK YOUR DEVICE. In this state, I've heard even sony need to replace entire motherboard.

well i have sony tipo dual st21i2 android phone and i have same problem with device my phone is dual sim phone and both sim are work well some time ago but when itry to update firmware using flash tool and than i see the 2nd sim is working stopped suddenly and sim 1 is working good and if i put only sim 2 in the phone its also working good and if sim 1 ony present in phone its good working also ,,,,,,,but problem start when i put both sim inside the phone and than i try different type of firmwares but no success bootloder unlock and relocked also but no result but my doubt is there i try a secret code and if this code is cause the problem in my phone *#*#7378423#*#* so if any one have idea to solve my problem please share here

Simlock

I am new to xda forums and ive searched through the forums to try find solutions to my xperia play r800i problem.
A couple of days ago i rooted it but many things went wrong. but me and a colleague managed to get it back to work..somewhat
Today my phone is restored with Update service program from sony ericsson but still i have issues with it.
After update service program and before that also i couldnt connect to any network, getting message saying "no service" and "Your simcard does not allow connection to this network"
Also everytime i start up my phone i have to choose language. it seems that my phone dont want to save language information i choose.
I tried calling my service provider and they only gave me manual apn settings but since apn settings cant be saved either i cant try that either.
I am sorry in advance if there is a thread with the exact same problem but getting rather desperate
Model: r800i
android version: 2.3.4
build number: 4.0.2.a.0.42
kernel version: 2.6.32.9-perf [email protected]#1
baseband version: 8x55A-AAABQMAZM-203028D-56
So is my phone completely broken now or is this something fixable?
Regards.

Havent tried changing kernel, firmware we tried with r800i_4.0.a.2.368_world.

Try to change to a custom Firmware and Kernel to see if its working better. Like Cyanogenmod or somthing like that.

Thats strange, bootloader should not be locked so that you can't unlock it. If so try to see if you can do something with bootloader files

I searched the forums yesterday and found that a guy named Aljendrissimo can fix kind of problem and i sent a message on the forum to him but havent gotten any reply yet, maybe if i wait until he replies and see what he has to say about this?

Ive searched some more now, and found out that i need to use SE tool 2 to unlock my locked bootloader, but before i started all this
issues it was "bootloader unlock allowed: yes" and now after all these issues its no. anyone have good idea why?

You can try on http://unlock-bootloader.com/this page, you might get a faster response.
It doesn't matter if your bootloader appears to be unlockable.

[q] network block after upgrade to 4.3

Hi community, as I stated on the title, im having a little problem here with the current 4.3 upgrade on my Note II.
Thing is I upgraded via Odin to 4.3 version; still, my provider service doesnt have the 4,3 upgrade, its only been released to free from fabric phones in my country.(downloaded from sammobile). Shouldnt have been an issue, but after i made the upgrade, my network got blocked. I ve read a lot of threads concerning this issue but still couldnt find a solution.
A link to possible answers would be super appreciated, or something.
Thnx in advance ! Hope i find a way to solve, have EFS saved in pc.
btw IMEI isnt wrong, its not a generic one.
It says : Service State : out of service
My phone number: Unknown
Rest of data seems fine...
Another thing is I sim unlocked the phone when it was at 4.1 to be able to use Movistar on it (via Galaxy S unlock worked) After upgrade network got locked again and asks for simlock code, tried with unlocker again and this time had no luck.. I dont know if the problem here its only that the sim unlock got locked again after the upgrade or what..EDIT: I cant use any of my chips, all of them throw "not registered..etcetc" msg... However this didnt happen when it was at 4.1
EDIT ONCE MORE: I ve been reading around, and seems there is no current way to unlock sim for all companies for note 2 at 4.3 ? Is this correct ? This is frustrating ._.

sry about the double post, anyone can confirm this last thing to me ? Is it correct there is no current way to unlock sim for all companies at 4.3 stage?

I have the same problem, and i found 2 ways to do it :
-either buy an unlock code ( about 25$)
-or downgrade ( if it's possible to 4.1.1, and use the classical way ( with samsung Code)
i hope that someone will suggest another way to do it

@julesarg, have you tried the patched kernel and modem from this thread?

[Q] Xperia Play R800i No Service

Hello, i have an xperia play which is R800i, it's bootloader unlocked, and should be network unlocked, if i go in that option with brackets like [] Network etc they are all with empty brackets and 0, according to some pages its fully unlocked, but still, i cannot get it to work, i've made several baseband changes, roms, etc,
what could be the problem of the phone? i bought it from someone that i usually buy stuff off, so i "shuld" be sure its not imei locked, but then, even if it was imei locked, would i be able to set a PINfor the SIM card? is there a way to check if there's a SIM card inserted in the phone from android? because i feel like it doesn't read my sim at all.
Please suggestions are welcome i tried everything, thank you

i can pay for a solution if its 100% working

He couldn't fix it because he said its after some week date etc, but really is there nothing to try?
Also what may be the reason after i flash a kernel it stays black screen? could kernel help resolve sim issues?

hi,replying cause i have same problem..i unlocked the bootloader with sony offcial method the second i had it in my hands and flashed a custom rom(everything working fine before the flashing..)..oddly i could use data(browser youtube facebook ecc working) but no calls or text..so i relocked bootloader and flashed with seus but nothing to do,same problem data working but no calls or text..then i unlocked again tried some roms,then decided to relock and give a try again with seus..now it won't recognise the sim at all,and NO FASTBOOT,it was working fine before the 2nd flash with seus,and i know for sure it's not an hardware issue...flashed many simlock.ta(changing the name to preset.ta) with flashtools..bot nothing.now i can only flash stock tft,since fastboot is no longer working(so i can't unlock the bootloader for the 3rd time), everytime after first boot it ask to insert sim and reboot, even if it ask for pin if i set it..so it IS reading the sim...the radio is bricked,been searching for 2 weeks now, and no solution found. i contacted alejandrissimo, he said he coul fix broken trim area for 20$, but it isn't answering to my messages anymore..sorry bro it looks like our play it's gone forever as a phone, so far..

I'm 100% sure having a locked boot loader makes accessing fast boot impossible? If you can still flash FTF find one for an ICS Rom and see if that fixes it

thanks for replying, i reflashed with wotan and now i have unlocked bootloader, and can flash but the problem on 3g stiil exist. i'm on superjellybean8, and sometimes it will lose the signal on 3g(but data fully working) i get emergency call only,i can browse and other data task like facebook etc, but no call or text, so i turn airplane mode on off until it gets the signal(wich sometimes is very very painful and slow..). i usually get no problem on 2g..so may i start thinking it could be hardware problem on the 3g antenna or something? i've been using it for a couple month now,if i could get rid of the 3g problem it would be great..it makes me miss some important calls you know..

I'm pretty sure the GSM attenna is on the top left on the opposite of side of the power button, have you dropped it recently?
Just occurred to me now, call your service provider and see if the 3G tower in your area is undergoing maintenance

no one knows?

Won't you mind if I join this thread?
I've got r800i unlocked from aliexpress which was working fine but had non-working touch-sticks.
So I tried to flash newer firmware (.79) and end up with 'no service' problem.
Like OP I have "[] Network 0" so it's definitley not become locked but it doesn't see my provider.
The funny thing is that it does see one of the local providers but only one of three.
Tried different ftf's, currently on R800i_4.0.2.A.0.84_Vodafone DE_(1247-8566).
The only thing I know from the original firmware (from flashtool) is:
Current device : R800i - CB5A1D6HYX - 1247-6268_R8D - 1245-8821_4.0.2.A.0.42 - WORLD-1-8_4.0.2.A.0.42
As I understand this one had Meteor IE baseband.
Is this problem has something with firmware or could it be antenna/hardware problem?

Thanks bro, but I sent the faulty device back to China. That's was the first idea - to change basebands, but that didn't help either in my case.
