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.
I'm at loss here. I recently purchased what I thought was a stock standard Note 2. It seems the unit is originally from Korea. It has supposingly worked here in Australia (where I am).
I have tried to flash any Rom, and so far I have tried at least 15 (currently have Speedwizz Cent 2.1). The only one that works is the one that I found for the Telecom provider the phone was with (Olleh in Korea). Is there a possibility I can't flash a new rom, I have no idea what version was there prior. The one that will flash has no modem, and has apk's in Korean. It's of little use if I can't get the sim to work.
I have tried a number of the suggestions here, including wiping dalvik, data and using the XDLL7 recovery.tar. Seems to make little difference. Either the unit boots and then sits in logo mode, or the screen goes blank after a while. So far, I have always been able to get to Recovery or Odin mode.
Any help most appreciated. I need to make adecision on whether to send it back/dispute in ebay, so I'll try a few more times.
I purchased a Verizon Note 4 N910V.05 off eBay.
When I got it, it had a custom ROM (didn't mention Verizon anywhere except for the logo on the back) and it worked fine with whatever SIM card I threw at it. At that time it was running Android 4.X
With time my phone started to get laggy and buggy, so I decided to reset to factory, and while I was at it, I decided to update to the most current official android version available to the phone: Android 6.0.1
Now, the phone won't use SIM cards I put it in it. It demands a Verizon one.
I read somewhere that I could just put one in, remove it, and then the phone should work fine with different carrier's SIM card. I tried but that didn't resolve my issue.
I also tried downgrading to previous android versions, hoping to root or do something -but no joy.
The phone shows the 4G notification and it receives (but not send) text messages -it doesn't send or receive phone calls -or data. I know the hardware is capable, because up until I updated to Android 6.0.1, it was working.
Does anyone know of a tried and true solution to getting this phone working again? Should I be trying to install a different ROM that's not for Verizon? Should I be trying to do something else? I'd really like to get my phone working again.
Any and all suggestions are appreciated.
Hey all,
I rooted my A70 a few weeks back and installed LineageOS and HavocOS, when I went back to stock firmware I found that I couldn't get any network - Just had the little circles for both sims - I posted about it here : https://forum.xda-developers.com/galaxy-a70/help/a70-network-service-root-twrp-lineageos-t3983635
Anyway, I restored all to factory settings and defaults but obviously Knox had tripped so O2 wouldn't repair the phone - expected.
I've bought another one since and have been comparing the two to see if I can get the broken one up and running.
Yesterday, after some research, I found that that I couldn't access the /efs/IMEI via ADB (old phone is rooted with TWRP/Magisk) - bearing in mind I'm not a developer, I did 'something' at that point and after a reboot, the phone registered on the network and I even managed to make some test calls between the old and new A70! The 'something' I did, I don't know, my intention was to check the CSC codes as per https://www.**********.com/how-to-change-csc-in-samsung-galaxy-phones/ - but never made any such changes....
So....I thought I'd 'fixed' it (more like 'f*cked it more lol), powered off and swapped my primary sim back and.... low and behold, back to square one. No network.. Swapped SIMS back, still no go.
What the heck am I doing wrong? It's clear this phone can get back up and working again, so, any pointers from anyone will be appreciated.
Thank you.
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
