after flashing my XA2 with the latest ftf on flashtool, i lost signal, the phone point blank wont read the sim card, i unlocked the bootloader and tried various custom roms to see if itd work, even sailfish but the issue persists, when i went to reflash it to stock using emma i noticed a message saying "the device requires activation with a dongle after applying this service"
this threw my mind back to when i worked in a service centre and when we flashed devices they too would have no signal unless they were flashed in the PC with the dongle in, so my question is does anyone know a way around this? i can get full root, custom roms etc without a prob, is there a simple command i can pass to re-enable the sim reader?

I have an Xperia Play and I decided to flash it with cyanogenmod. First version I got working was the 7.1.0.2. Everything was working fine except for my network: the phone didn't even ask me for the PIN.
After this, I tried the experimental CM9.0 RC1, yet I found the same problem: SIM card not recognized, phone didn't ask PIN, no networks found.
At this point I realized I didn't install a baseband on my phone and tried that. I started flashing it with flashtool, but then forgot to install the .zip file from CWM.
With this the phone was asking for a PIN, but soon afterwards it asked for a "SIM network unlock code". My phone is not sim locked.
After I installed the baseband -36 correctly (with the .zip file from CWM), it returned to behave like before: no PIN asked, no networks found.
Is there a fix for this? I searched for a whole afternoon for this, didn't find anything. I'll give further details if needed, thanks in advance.
By the way, if I revert the system to the stock sony ericsson ROM everything works fine. My carrier is "3 Italy".
EDIT: Installed CM9RC2 and now everything works fine except for wi-fi. Well, i suppose it is to be expected from experimemntal builds.
I flashed in JB AOKP was working fine all of last night. I also entered my SIM Pin or unlock code. The first time I put in an 8 digit unlock code I have. Second time it prompted me I skipped it. I'm pretty sure it was the security pin and not the network unlock. I don't have any other phone's micro SIM I can insert into my phone and a local phone store's T Mobile SIM produced no different of a result except for replacing AT&T with T-Mobile (I have not however put my microSIM into another phone...because I don't have another micro sim phone). Reboot phone this morning and it's no longer working. Tried to enable 2g. Nothing. Tried a battery pull with the phone on, pulling the SIM (same message with SIM pulled out),
Wifi works
This sucks big time ;(
Note: I am pretty sure I did not network lock the phone or anything because the SIM prompt that came up when I flashed JB did not ask me for my unlock or network code (I would have known). The first time I entered that code was 'just in case it's asking me to unlock" but why would it ask me a second time then? So I doubt it was prompting me for a network unlock code. The prompt from youtube videos was different too.
Also APN is empty, but I think that's becasue I'm not connected to any network
Pressing Available networks brings up AT&T AT&T AT&T T-Mobile T-Mobile "311660" pressing any of them you get a quick window connect "too fast" goes back to/stays in available networks screen and says "Can't connect to this network right now. Try again later."
So I added the AOKP and Corresponding kernel yesterday and I mean it was working fine with 4g... apparently this thread says that you need to flash a new radio in some cases when you change kernels?

...what are you talking about. My IMEI isn't mentioned once in that post. In fact now that you mention it, since people's IMEI changed...nothing like that my phone still has its IMEI
I also did not get a "phone frozen" from entering the wrong code too many times...so I doubt its locked like that. There was a random reboot that I WOKE UP to, but nothing weird...it rebooted randomly but worked finely after that

I was proposing the theory that you may have lost your IMEI, since the symptoms you report were very similar to what I was experiencing when I lost mine, however since you still have yours, must be something else, eh?

Well, mine was definitely due to a lost imei that happened sometime when flashing.
I did get the network unlock warning thingy twice, and then had no cellular connectivity, which is why I mentioned the lost imei. I restored my nandroid back to stock, then used the method here with a little driver tapdancing to reinject my imei, and that solved my issues, but sounds like you have something else going on.

If I flash back to stock and no longer have the stock kernel, what is the steps for flashing back then?
1. flash stock kernel
2 fix partitions
3. factory rest/cache/davlik
reboot into oden and flash new image?
Long story short, Don't cut your own microsd..the sim pins on this phone are VERY sensitive and hard to fix/see. Don't bend em.
I am having the same problems right now, I keep on getting " NO SERVICE" - SELECTED NETWORK UNAVAILABLE" Error.
Rebooting doesnt help, flashing modem through CWM doesnt help. I know for a fact that the simcard it good because other apps that I install can read the sim with no problem, and my WIFI is working like a charm.
Someone got a solution for this? This is already like 4 days ongoing, please any help will be appreciated !!
Im having the same no service selected network issue. I can search and find att and the mobile but when I try to have it connect to att that's the error I get. I have an att SIM card in the phone. Sph l720 SIM unlocked, it didn't ask me for an unlock code or anything like that but I also don't get the invalid SIM card error. I've added the main apn from the att website but that doesn't help and the phone is current set to gsm/umts. If anyone has a fix please let me know, thank you.
Ok, so I updated my s3 to 4.1.1 but after a week of using the update, I still hadn't seen any sign of the expandable notification options. So I decided to re-install the update by flashing via Odin, which I did. After the flash, the expandable notifications still weren't available, so I instead flashed the stock firmware, hoping to update from stock and see if the problem was fixed. Unfortunately when I rebooted after the stock install, my phone would no longer connect to data, or even to the network period. I can't text, make calls, or connect to data. It shows full bars but when I try to do anything it tells me the network is unavailable.
I tried a lot of options for fixing it:
-I checked all my network settings. Data was on, I switched into and out of airplane mode, no luck.
-I tried to set my network operator by manually selecting tmobile. No luck.
-I tried re-entering T-Mobile's APN settings. No luck.
-I tried to restore from a backup I made of my 4.1.1 when it was first updated. No luck.
-I tried flashing multiple versions of stock firmware, as well as cm10. No luck.
-I checked my IMEI, it's correct.
-I flashed a few different modems. No luck.
I've run out of ideas and I can't find any other ideas in the forums. The closest I have come to getting a fix was during one instance when I was flashing stock again, I cleared my cache, dalvik cache, and did a factory reset as well as formatting my internal storage. When it did the first boot it had service for about thirty seconds. I was able to receive a few waiting text messages, and I had edge data for the remainder of the 30 second or so period. Then I lost data again. Every time I boot a notification ticks on my status bar that says "Restricted Access Changed" and before I can pull down and tap it, the notification is gone. When I try to set a Network Operator, it says something along the lines of "Unable to connect, not registered on the network." I'm stumped.
Has anybody else had this problem, and does anybody know how to fix it?
Just a guess, but perhaps T-Mobile has blocked your IMEI? Did you buy the phone off of someone or straight from T-Mobile?
Did you ever report it lost or stolen?
Only thing I can think of given your scenario.

I bought it through Costco as an authorized upgrade offer by T-Mobile. I can't imagine any reason why my IMEI would be blocked. I went to the t-mobile store yesterday and they told me that it should be working and that I should take it back to Costco and see if they can do anything for me in terms of replacement.
Problem Solved!
Apparently it was because when I got my phone they didn't give me the upgraded sim, they just cut my current one to fit the microsim slot. Go figure. This could have been solved by tmobile last night if the guy hadn't refused to help me just because I had rom manager installed on my phone. Just because I have a root program installed on my phone doesn't mean my phone got messed up playing around with root. Anyways, i updated my sim card through tmobile's phone service and I'm a happy camper now!
I have disabled the network lock way back using the *#197328640# Perso SHA256 OFF method and it has been fine for few years when I used different SIM cards while travelling. However, last week, while I was using a third party SIM card, been on it for a few days without problems (also using the same company SIM card in the past). When I try to browse Google Maps, I lost data connection and the phone rebooted.
Upon startup and entered the SIM PIN, it ask me for NETWORK LOCK PIN. And because I have upgraded to RR Rom (Android 6.x), I can't use the same method to disable the network lock.
Any ideas how to fix this?
I am thinking to reimage my phone back to 4.4.x, but I have read it is dangerous and very high chance or bricking it?
The part I don't understand is how or why downgrade will brick it? If I wipe my phone, do a fresh install of image (or even restore from old TWRP images) including the old RADIO ROM, that should be fine, right?
Furthermore, where is the network lock (NVRAM) data kept? EFS?
Flashing back to the latest stock rom via Odin isn't any riskier than flashing a custom rom from my experience with Samsung phones.
Hey All,
So I've had issues with my phone where I rooted it and messed it up to the point where it no longer registered on any networks (tried several providers here in the UK). A few days back trying to get it up and running I managed to get it registered on the network (this after reloading various software versions, some failing some not). After powering it off and back on again with my primary sim, I was back to no network (I have two A70s). Swapped SIMS back (powered phone off) and again, no network.
This morning, I started again (Installing TWRP and was planning to root again):
- Flashed stock firmware using ODIN.
- Unlocked bootloader.
- Flashed vbmeta.tar (v3.3.1-5 from Grarak).
- Rebooted, wiped data/cache
- Rebooted, started going through the setup and noticed it was on the network! (have not flashed TWRP recovery).
I'm reluctant to power off again and wondered if there's anything I can do now whilst it's working and registered, making calls etc. The reason being, I've got 5 days before I can return the other A70, if not, I'll be stuck with 3 O2 contracts
Besides the usual backup (Google/Samsung/) - is there anything I should do via ADB? It's not rooted and TWRP is not installed, I've literally just flashed vbmeta.tar from Grarak's TWRP post....
did you try installing a custom rom. i am on havoc os n i own A70FN. i believe havoc works on A70F/FN/Q. the only issue it has is of fingerprint and volte but since i don't lock my phone that's not a problem for me.
other than that the rom is stable no reboots no crashes or anything. so maybe try a custom rom just make sure ur model is supported. n besides even if u r afraid of rebooting there's bound to be a day that the phone would need a reboot.
So i say go ahead root it, install a custom rom.
also i remember having this sim issue myself. my sim worked in all the sets at my home except the A70.
i had to get a new sim n it just started working.
Try some other sim in your A70.
Also rooting shouldn't cause such a problem. from my experience i believe its something else.
i have rooted several phones n never got a network issue. i even messed up the the rooting process on the A70 n either ended up with a bootloop or occasional system crash but no network issue
