Your device is not compatible with this version

Hello everyone, who have same issue with some app in google play store? Or my phone is broken? I tried to install Kaspersky which one I bought to my atrix 4g and on the top of page "YOUR DEVICE ISN'T COMPATIBLE WITH THIS VERSION". Same result when I tried to install Canon Easy-PhotoPrint.

Contact the app developer. They probably have to update it to support the ion.

I had the same problem with my LivePhish app. I solved it by flashing the international firmware and was able to download the app again. My guess is the AT&T firmware has some type of restriction.

Thank you Spectre. I contact with kaspersky two weeks ago, and stiil no answer from where. From my pc experience in russia nobody reeding e-mails. It's working just when you calling direct to Moscow. I'll try to flash international softwware, but can you tell me, do you have any problem with att&t LTE DATA with international ROM?

I had it on my ion briefly but did not encounter any issues. You just have to manually put in the at&t lte apn once you flash the firmware.

[Q] Very poor CARRIER NETWORK

I got this used xperia S lt26i, everything is great, its on 6.1.a.2.55, rooted and all. But the carrier network on this is very very bad. I don't get any network signals unless I am standing under clear skies. That too for few minutes and it drops. Since it is out of warranty, I can't even get it replaced. I tried factory reset, repairing with EMMA, updating with pc companion, flashing rom with flashtool and all is in vein. I changed 7 sims as well, still no luck. Can anyone tell me how correct carrier network reception? Wi-Fi works great, so does the radio and everything else. Only carrier network is all bad. Please help me, can anyone suggest me some remedy? I heard changing baseband may help? But there are no basebands for xperia S anywhere on net, please help
It's not phone problem. It's your carrier problem.

Tried the sim on 3 phones as well today. On other 2 it works great, on my xperia s it doesn't give me network. After a bit research I got to know that my cell is purchased from U.S and the radio/baseband here in India works on different wavelength. All I think is if I can get a baseband from .45 Indian firmware, I shall be getting network. I am on .55 now and dont want to go back to .45 as it was very laggy. Please suggest

Unlocking a sgn2 on O2 network (uk)

Hi folks.
I'm switching networks from O2 to talktalk (vodafone) and I'm wondering if anyone can direct me to a free method of doing this. I've watched the videos on youtube that allow it to be done by dialing “*#197328640#” on the phone but when I enter the network lock section it says "MENU NOT EXIST"
I'm guessing this is an O2 thing so can anyone help me find a way to get my device unlocked?
ps. Hope I have this in the correct section. I've also tried searching on here but no joy.
Thanks

GalaxSim worth the couple of bucks.
I think you have to downgrade to a 4.1.1 rom first, unlock your phone then flash a 4.1.2 rom.

I've tried using galaxsim but I'm getting
"unable to read NV data"
You guys are saying it's worth the money but the app appears to be free. I can't see a paid version only a free version.
It will ask you to buy if you want to use it to unlock.

Thanks for the reply's folks.
I downgraded to 4.1.1 to try using the *#197328640# method but that hasn't worked.
I've tried using the old version kdogguk posted but i'm getting invalid IEMI number now but it's saying my phone is unlocked
my phone is locked tho as it won't take my new talktalk sim.
My phone was stuck on boot screen when I downgraded and I had to root though odin then reset it before it would work so I think I've downgraded to the wrong firmware as it is now branded O2 firmware where as before even tho it was locked to O2 the firmware was neutral (not O2 branded).
I've rooted as I said but it won't install custom roms so I have a problem now. Going to upgrade to 4.1.2 but need to make sure I have the right firmware this time.
I'm having some time of it right now lol
This galaxysim app is now saying my phone is unlocked but it won't take my talktalk (vodafone) sim
Still no luck? My note 2 was on o2 first thing I done was root it, tried that code but didnt work then used galaxsim its free but said it could be done paying £2 something. Then I installed a standard btu rom. Funny thing is not tried diffe sim yet. Just hate locked phones
Where abouts in UK are you?

on my phone it says my device is unlocked but when i try to call any number it says not registered on network, what's the problem?
turn off data. turn off mobile. turn them back on. reboot.
Galaxsim was saying my phone is unlocked but it wouldn't take my talktalk sim. I ended up paying £9 to get it unlocked on ebay. Working fine now.
Strange because my phone is O2 but I've been running it with a 3 sim from day one.
They should be unlocked by default.

[Q] Your SIM card does not allow connection to this network

I have searched XDA forums and there are HUNDREDS of similar posts, still 0 resolves.
I have bought Optimus G and went to my mobile carrier to receive my new MicroSIM. I put it in my device and I had connection for 20 minutes, and I got a red X on my upper right signal indicator. When I try Automatic registration in Settings > Mobile carriers, it searches and says Your SIM card does not allow connection to this network. My PIN code is correctly working and my phone indicates a SIM is inserted, still no connection.
On my lock screen I get - "No service" message next to a SIM icon. Any help appreciated ))

Thanks for the response.
I can only enter New APN, and when I do so, my phone only uses those provided by default from carrier/sim and not the newly entered one

No sim card and no connection
I have AT&T's LG Optimus G E970 with E975 firmware flashed. When I insert any gsm sim card phone tells that there is no sim card and no connection. I think it happend because of not properly backed up EFS partition. Any user of E970, please send me you EFS!!! I don't know how else I may return my connection back. My e-mail is [email protected]

I had the same problem this week.
I was running savyrom for a couple of weeks without problems, but this week I've got this no service problem.
Avert reflash savyrom v2 (wipe cache and dalvik only), I had a subsystem crash and afterwards kernel crash, even after restore a CWM backup of stock ROM.
First I thought that it was normal because I was in a place with weak signal, but I was not able to connect to the network anymore.
At the moment the phone don't charge because I'm having several kernel crash's.

N5120XXCMH2 UK No 4G ??

Hi
My device came from HK, with the 4.1.2 HK firmware. I updated it via ODIN to the the UK 4.2.2 MH1 firmware. On both of these firmwares, 4G worked just fine.
I then updated to MH2 by Kies as it offered to update the device. My 4G stopped working.
Has anyone else had issues with EE 4G in the UK on an N5120 running UK 4.2.2 MH2 firmware?
Nigel
dumb answer...But did you try restarting the device?
Sent from my GT-N5100 using Tapatalk 2
Aye, restarted many times! and reselecting the network manually (rather than autosearch). Fixed now. Fix is to goto settings - more settings - mobile networks - network mode then change it from LTE to something else I.e WCDMA let it find the network, then change it back to LTE again, then it finds LTE network.

I would suggest, using mobile odin, flashing the working 4.2.2 MH1 firmware, but removing all the data but the modem. since the MH1 modem worked on your providers 4G it should work just as well on MH2. Then you would not have to redo the procedure of choosing WCDMA. Or did it fix the problem completely so that you still have 4G after reboots etc?
I always flash with Mobile Odin and i am still on my 4.1.2 modem that came with the N5120 when it was new.
My 4G also stopped working after i flashed 4.2.2, but reverting back to the old and known modemdrivers did it for me, and since there are no swedish release of 4.2.2 yet i will keep my old 4.1.2 modem for the time beeing
O :D

Thanks to the replies. I just bought a UK N5120 frpom Three. Decent deal £370 and one month rolling contract 1GB data £7.50.
Unfortunately I think the sim is data only and although the dialer works the network voice tells me I cant make calls. I'll have to try a payg sim to see if dialing works.
