Just got Samsung Nexus Korean maguro variant yakju with 4.1 installed and with Baseband: UGKL1 and my network is Warid Tel - Pakistan. I used my local sim in as well and it was working fine. Today I tried to use custom 4.3.1 in it and so I done these steps:
Downloaded Nexus Root Toolkit, Android SDK, Latest Nexus drivers and all pre-requisites before starting. Now I first started to unlock my Bootloader with matching requirements as the tool already do this. Then flashed cwm touch recovery and applied root. I tool backup of my stock rom via cwm and then wipe all and installed liquidsmooth 2.7 which is jb 4.3.1 and it worked like a charm. What i noticed afterwards that the rom is reading my carrier details correctly but also showing Emergency call only warning as well. I tried Edge as well and it was wokring normally but when i tried to dial a call and tried to send txt it showed me Mobile network not avaialable. Then I tried all latest radio basebands on it, tried all settings SMSC and normal troubleshoots but couldn't get complete carrier support. Then I restored my default stock rom via cmw and boom no issues like it should be. Now my question is did I missed something for it? or am I flashing wrong basebands? or somthing else? After too many hours i felt that I cannot go further from here. I am attaching my screenshots. Please if anyone can tell me or guide me I will be very thankful to him as I haven't tried my phone yet, just got it. I had HTC evo 3d and its setup of everything never got me stucked like this.
Anybody up for help kindly

Updated to 4.4.2 today via ota. Was originally a Verizon 8.3 lte, switched to t-mobile. Was able to toss a sim card in and update apn ran fine. But after ota update today it no longer reads tmobile sim card. Have updated apns, continuing to get notifications that tablet activation incomplete, your tablet will try again when you restart. Have restarted plenty of times, on boot get welcome to Verizon red startup screen. Then goes to straight to screen unlock. Anyone with a idea of how to fix this. Tablet is rooted.

same here... I skipped the initial setup steps. Device shows no network connection to t-mobile. When I go to Settings-> About Tablet-> Network, com.android.phone crashes
To go back to 4.2.2:
Root, Flash aboot.img and TWRP.img
http://forum.xda-developers.com/showpost.php?p=54533937&postcount=2
Then reflash 4.2.2 TWRP backup (dunno if you can do direct flash without factory reset... try?)

most likely you'll lose your files/apps/settings... unfortunate

http://code.ngvincent.com/android/modem.4.2.2.img

Code:
adb shell
su
#backup current modem
dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/modem.backup.img
#restore modem from 4.2.2
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem

Doesn't work
Same. Anyone have a fix?
I fixed mine. I had to reactivate it with a Verizon sim card. Go through the whole process. then i was able to pop in a tmobile and add the APN settings for Tmobile.

Did you use an active Verizon sim ?
We are getting a new Verizon G pad. Do we need to insert a Verizon sim, upgrade to kitkat and then insert T-mobile sim?
Thanks for your help

Mine was already on 4.4.2. I just inserted an active Verizon sim card, went through the setup process, then swap out the sim cards.
i run this line of code and i get operation not permitted , im not sure what im doing wrong. ive tried it over a few diffrent computers, and have also ran adb of the tablet it self thru term... any ideas?
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
also its rooted with TWRP and CM12.1 installed but i have no cell service the options in settings are grayed out i cant enter and settings manually. and the Network app wont work to change anything
want to set it up to runn off AT&T the best i can
Did you give terminal Superuser permissions with "su"?
yes super user was granted
I don't know what's wrong then.
You could take my ROM zip from my signature, delete all the partition IMG files out of it, put the modem.img you want in, and edit the updater-script to remove anything having to do with flashing the other partitions, then flash the resulting zip in TWRP. Make sure you know how to recover and have everything saved that you want to keep from internal storage in case you do something wrong, though.

You know, I haven't been able to get mobile data working on any CM-based ROM on the VK810 yet, so that's probably your trouble. If you want mobile data you'll have to go stock. Some people had some luck on CM-based ROMs but then eventually it stopped working. I didn't have any luck at all.
Thank you for the info, I think I'll just wait for a possible workaround, until then I'll just use internet share from my phone.... That and I haven't the foggiest idea hownto do what you told me to do with the updater and what not lol , so rather than really screw things up, I'll just stick with WiFi..
Really not sure what to do here, and I'm starting to get very frustrated, especially since I know exactly what the issue is and I can't find a solution... So here is everything I did up to this point in detail. I wanted to go back to stock for a while, but I remembered not being able to update at all last time I tried this. I used the LG Flash Tool to go back to 10b (I think? Earliest firmware out there) It started when my phone would tell me that "My Device was not registered yet" in the System Update settings. I did some Googling and found out it was because my IMEI number was blanked out (All zeroes), and I found a tutorial that was for the G2, but worked for the G3, to repair the IMEI. I first rooted with the LG One Click Root Tool when I got to Lollipop, used the IMEI that was under my battery, converted it to HEX and injected it into my phone with RF_NV_Manager, which was installed with QPST by Quallcom. After doing this, my IMEI was fixed, it matched the same IMEI that was under the battery on my phone, though I never texted or called anyone from there so I never noticed anything strange. I was able to update to the latest official Lollipop firmware, but then my phone started telling me I left the home network. Thinking it was just a glitch or something, because I had roaming issues before on stock, I switched to a custom ROM since that fixed it last time before I even knew that IMEI's existed. That didn't fix it at all. I was on LiquidSmooth Alpha and my phone will still go to roaming, and the way I would fix it was to piss around with the mobile network settings and change them back, then I would get 4G LTE for a few minutes, but I would NEVER be able to call or text. Since it was a discontinued ROM, I thought I just got unlucky, so I went to an official Nightly for CM12.1. At the moment I have LTE but no calling or texting... Then I found out that these issues tend to occur after IMEI fixes, so what do I do? Can anyone point me to a proper tutorial on how to fix this? After looking, I ended up downloading and installing something called EFS Professional 2.1 but now I'm even more confused...
EDIT: I tried going into ADB and inputting "adb reboot nvrestore" but that didn't fix it... The site said it's based on a backup that was automatically created when the phone was first built but that was on a completely different forum for a different phone. Going to try to flash back to stock KitKat.
EDIT: Alrighty! I'm getting somewhere! I flashed back to 10B with the Upgrade DL option, before I used Board DL. I can call and text now, as well as LTE, and OTA updates work, but I'm just going to root and go straight to the Nightly CM12.1 that I wanted to go to in the first place.
EDIT3: That seems to have done the trick. For people who have had issues with roaming after IMEI repairs, try flashing your stock TOT with the Upgrade DL option, then root and install your preferred ROM.
Can someone please help me.
A few days back I attempted to root my SPRINT NOTE 4 (SM-N910P) Android 5.0.1. [/B]The first root was somewhat successful, however it did not trip KNOX. When I tried to Re-root it, I bricked my phone. In a panic I tried to wipe my phone and restore back to STOCK, but mistakenly selected/checked to wipe the INTERNAL data using TwRP Recovery and totally wiped the phone clean. I then called Sprint to have them switch the line back to my NOTE 2. I think that, there is where I made the mistake. I should have left the line on my NOTE 4 and then Re-Installed the STOCK ROM or a Custom ROM.
I eventually installed CYANOGENMOD 12 (CM-12) hoping that somehow it would fix my problem. Well CM-12 worked, it installed perfectly. I even reflashed back to STOCK, but I could not connect to SPRINT'S LTE Network at all. So, I could not activate the phone. I have played with all of the suggest APN Settings to no avail. I took my phone back to Sprint help but they said that they could not help me because the phone is no longer in their system. I have be searching a FIX for days and no one seems to know how to fix this problem. Can someone PLEASE help this NEWBIE out of the tight spot that I have gotten myself in.
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
