Need help re: Updating Android on Sony Xperia Z2 Tablet - Android Q&A, Help & Troubleshooting

These tablets were exclusive to Verizon as I understand it. I posted this to XDA Assist but perhaps this is the better location.
I have used my tablet for most of the time I've had it without a SIM. It's fine except I can't get any updates to Android. I'm a T-Mobile customer and I recently got a SIM, hoping that would help get the update. (I've had lots of Xperia phones and they all--except the Z3--got updated to Marshmallow over T-Mobile's network.) Sadly, it did not. I've spent quite a lot of time on the phone with T-Mobile, Sony, and Verizon. I've googled the issues and found no solution other than getting a Verizon SIM. But that costs $40 and will be non-refundable.
When I try searching for an update via wifi, I get "Error during DM session."
When I try searching via T-Mobile's data network, I get "No network found."
T-Mobile suggests a factory reset. But what I've read says that will do nothing but cause me to have a headache putting it all back the way I want. Sony says to contact Verizon. Verizon says to contact Sony, find a friend with a Verizon SIM I can borrow, or ask a Verizon store to borrow a SIM until I get the update.
My 13yo thinks-he-knows-everything son, thinks he can do it with button combinations (power-volume, etc.) but I won't hold my breath. I had an issue with this tablet in July which kind of messed up things like that. It powered all the way down due to an issue with our rental car's power ports. Then, after charging on a magnetic charger for hours, wouldn't turn on. I plugged in a USB and it still wouldn't turn on after charging. No lights no nothing. Eventually learned about the little button beside the SIM card slot and it came on again. But will it not charge on magnetic chargers anymore and it doesn't not want to cooperate with those button tricks.

Radio GA GA - Help!

Hi Folks,
I was having the issue with my Vario II (on my 3rd Handset) where the phone enters standby and never wakes up until a soft reset.
When the 3rd handset arrived I decided to bite the bullet and go for WM Black and see if it made the handset any better. Unfortunately, as good as the new ROM (now on V2) is, it didnt solve my hanging issue.
The next thing I decided to do was change the radio ROM. I first went to the 1.38.10 and then to 1.38.11 and then to 1.27.00, as the later was decribed as being the most stable.
As you have probably guessed by now, the issue still plagues me....Even more so since the radio upgrades. The symptoms are as follows;
- Some calls I answer go silent after around 30 secs and I need to soft reset
- The phone can show full bars of signal but the phone diverts to answering machine
- When connecting to the internet, the icons shows as connecting but then drops to no signal (showing a !) then after a while will start to reconnect. Sometimes I need to soft reset to get the connection again
I am wondering if there is something else I am missing that could be causing the issue. I am using it today with no apps and still have the same issues as above plus the freezing issue.
Is there anything else I can change???? or am I just cursed?
Any help would be much appreciated.
Cheers and thanks in advance

I would say, try your SIM card in a TOTALLY different phone (not just a different Hermes) As you would have to be fairly unlucky for it to happen with THREE seperate devices, especially with different ROMs also.
If there is a handset available to you that is either a tmobile or SIM unlocked.....give it a go.

I belive it's your SIM card also..ask your provider to replae the SIM card for you. Just tell them your issues and it happened to three handset with the same SIM. I bet they will able to replace the SIM card without charge.

Yep SIM cards cost JACK ALL to the providers. If they do charge you then thats gotta ring alarm bells!!!
Hanging on wake-up was my big disappointment when going from Vario I to Vario II.
It decreased after upgrading to WM6 (first black 1.2, now black 2.0). In my case the SPB mobile shell also did not seem to do the problem any good, probably because it starts the 'now' screen on wake-up.
I have not much software on my device and have very few hanging issues.
I work for a Cingular retailer, and I just signed my fathers business up. Someone had told me that the IMEI on the account had to match the phone on a 3g phone or the exact same symptoms you are seeing would occur. I confirmed it with my pop's business. the three people using 3g phones had serious problems with calls going to VM, not getting txts, and poor service in general. Once i fixed the serial numbers Cingular-side, everything was peachy. This happens to be my first post (longtimelurker) so if I'm full of ****, feel free to tell me. Check with your service provider and make sure they have the right IMEI on file. If not, you'll prolly have to go to a store to have a clerk fix it, but it'll be worth your trip if im right .
Hope I helped.

I don't think IMEI is the issue here. I just signed up with Cingular and got a Motorola K1..but the SIM is a 3G sim. I simply pop that into my Hermes and it's been working for 2 month now without any issues. Another thing with Cingular...the IMEI on their database is automatically updated..it's not like you have a Motorola phone and switched the SIM to a SonyEricsson phone and still using the Motorola IMEI #....it will not work that way. In fact, all GSM providers will automatically update the IMEI in their system once the SIM is registered in their network. I can confirm that with my HTC tytn with the Cingular's online account. You can check the online account pretty much on what type of phone you current have. If I use the Motorola K1, the online account will be updated as unknow phone due to it's new I guess...but when I use the HTC tytn..it's automaticlly updated as HTC 8525...even I manually change the phone type to other phone...after couple minutes..I log back on and it will show the HTC 8525 again. Base on this, I am sure IMEI is not the issue here. One thing to note is that I did get that hanging on wake up when I have the SPB software installed.
i can concur about the IMEI... i havent changed my IMEI on my account since i had a sony ericsson a few years back... and i have no data problems.. i take that back, i had some when i first got the 8525, but then found out i needed the white 3G sim, since then it has been flawless.
Awaiting Sim
Thanks for all the advice. I tried the phone with someone elses sim card the other day and it seemed to behave itself. I am going to phone t-mobile and ask them for a replacement SIM.
Will let you know how I get on.
Cheers

AGGGHHHH!
It doesnt get any better....
I just phoned T-Mobile and asked them for a replacement SIM to be sent out. The girl I spoke to said that she could order me a new SIM which would be out in between 1-3 days but she would have to disconnect my current SIM when the new one was despatched! This means no phone for this time, which I need for business
I asked whether I could phone for activation when the new SIM arrived but this she tells me is not possible.......AGGGGHHH!
She did suggest that I could pay 15quid for an 'interactive' swap over at a T-Mobile store but I have issues getting to a store during the week and they are then going to see that VM6 Black edition is on the phone!
Any suggestions?

What the hell?!?! Thats bullcrap if ive ever heard it, when i got a replacment USIM from O2 my existing one worked until i called O2 to activate the new one? Maybe T-Mobile has a backwards way of provisioning them?! That sucks dude. Suggest you call them again (if you havent already got an order through) and do another request...you may hit the jackpot with a different operator?!

As far as I understand how GSM works...The T-Mobile lady is correct. You can't have the two SIMs having the same #, one has to be deactivated before the new one is active. But if you are sure the new SIM will get to you in a day or two, you can have them to schedule deactivation of the old SIM two days later, schedule the new SIM to be active in two days..the only donw time you have is probably a an hour or two if the timing is correct. If you are able to go to a T-mobile store for direct swap, you can get the new SIM working within an hour but they shouldn't be charging you $15 at the store even you have WM6 black on the phone becasue the phone is not faulty, the faulty part is the SIM and they should honor their warranty.

Agreed on the warranty there dude.
O2 simply sent out a replacment USIM, obviously not activated yet. It arrived and i called them, they took the sim card number and said I should lose reception on my existing sim (it wasnt 3G ready) and thats when i should put the new one in, as soon as i lost reception i swapped and it was working (got the U symbol straight away).
I figure T-mobile would do the same?!?!
Bit the bullet yesterday and paid 15 quid for a new SIM card. It has made he haw difference. Still got major issues. The phone has no signal most of the time and even on the rare occasions when it does, the calls go to answerphone.
The signal shows an exclamation mark (!) and the only way I can get rid of it is to do a hard reset and it works for a couple of hour (or less). It is as though it is constantly in flight mode.

Had to exchange my phone today...

Had my note for a week and it would never work right on any AT&T hotspots. It would connect but I would get a notification that the connection failed, basically it seems that the authentication failed as I would get no data despite still showing connected in wifi connections. They gave me a new sim along with about 2 hours of wasted time doing other crap. They eventually put my sim in another handset and it worked. Come to find out that 4 other people have had the same problem in the past couple weeks with their Note. One of which was there at same time and his started working about ten minutes after a sim swap. The other two both got new phones like I did. Something you guys may want to check out, especially if within the 30 days. I spent the past week skimming through and installing apps suggested apps, time to start over.

UGGGHHHHHHH I hate when I click "Thanks" instead of Quote. Ugh.
Anyway, so they swapped your phone when they just needed to swap the SIM? Brilliant...

First, thansk for the thank anyways!
Second, No I did need a new phone. They swapped my SIM with no change. The one guy got a sim swap and it worked for him. Took awhole new phone for me. But I'm big on getting what I pay for. They used the free wifi as a selling point. I will very rarely use it, but first night there I was at McDs and got a connection failed notice. If i'm paying for it, it'll work one way or the other, especially now that I dont have unlimited data.
Just because it connects to a wifi spot doesn't mean you get internet right away. You still need to open up a browser and confirm to their terms and conditions before the internet works.
Yea I know, it wouldnt do that though. The browser tried to connect and got nowhere. The key to the authentication fail is that network connections showed it connected but the ATT notification said connection failed. This is the safeguard that keeps all but ATT devices off the network, a function of a implicit deny rule.
This is prob meant for another thread but they really need to make those ATT Hotspots recognize that you're on an ATT phone and auto connect without having to hit accept on the Terms and Conditions. I have times when my mother and aunt are at a Starbucks and they'd call me saying they're on the wifi but it's not working. I gotta keep telling them to open up a browser and hit accept on the terms and conditions.
BTW, does anyone know if you nuke/freeze the AT&T Hotspots app, does this prevent you from using ATT Free wifi?

I've never had to accept any Terms and Conditions on an AT&T device at an AT&T hotspot. If I go to Starbucks, the phone connects without any prompting and gains access, a little AT&T hotspot indicator appears in the notification bar. If I try to connect with my laptop or a non-AT&T phone, I have to accept Terms and Conditions.
I also had to exchange my Note this week, after about 10 days of use. The phone was in the car holder and it rebooted. It then started boot looping where it would display the Samsung splash logo, and then reboot. It would not go into Recovery, though would go into Download mode. AT&T tried to reset it for 20 minutes and then gave up and gave me a new phone.

Samsung Galaxy S2 SGH-I777 Not Registered on Network

Hey, so, I bought a samsung galaxy s2 from ebay, from a good seller with 5 stars, and when I got the phone, it came with root, which is all good with me, but when i put my SIM card in, and tried to call my home phone, BOOM Not Registered on network. I have spoken to T Mobile customer service, and they verified that the IMEI is NOT stolen, but the IMEI on the phone is not the one under the battery. I've search every entry about this on every site I could find to no avail. I will now list everything I have tried. Also when I turn on my phone it says something of MM#6. When trying to connect my phone via usb, it doesnt show up. (I had to use MobileOdin)
- Unroot
- a mixed amout of taking things apart and putting them back again
- ReRoot
- Flashing a Kernel and System to go back in time to GingerBread
- Getting a new SIM
- Using an app called Ariza (My Phone Is Not Supported)
- Spending an hour talking to customer service
- Going to Settings, Wireless and Network, and searching for my network
- Resetting a whole bunch of stuff in Wireless and network
So, if you find a fix thats not on this list, do tell... I have a 30 day warrenty on this phone, but I would rather not like to wait a month for them to figure out the phone is horrible and to give me my money. I hope somebody found a fix in my fails, but if you know a fix not there, help. me.

Verizon LG G3 Phone not registered + IMEI all zeroes

I just downgraded my Verizon LG G3 down to 10b from 12 and rooted it, did supersu and flashed TWRP and all is fine there. I then checked off Survival mode in supersu as well. When I went to my update section in settings I got the message that my phone is not yet registered. Now I did read those other threads that explain that when using a flash tool you need to pull out the Sim card, which I didn't do nor did any one of the guides that showed me what to do say anything about that step. So is the fix going to Verizon and buying another Sim card and then inserting it and doing a factory reset? Will I lose root if I do this? Is that basically what I do? Turn the power off, remove the old Sim replace it with the new one turn the phone back on go to settings and do a factory reset? Will the Sim activate that way or do I need to let Verizon themselves do this for me? How does the new Sim get reactivated for my account?
EDIT
And now I am noticing I am getting downgraded to 1X instead of 4G about a half hour after I reboot, happens every time. I assume that is due to the Sim card issue as well
EDIT #2 Damn now I notice my IMEI number is 0000 0000 0000 0000
Damn I guess I am screwed, thought I would have some answers by now lol. I regret rooting the phone....
Has this not happened to anyone else? Losing the IMEI number but the phone still works? The only major issue I seem to have is I can't use OTA to get back to build 12 because I get that message saying the phone is not registered yet and also about 20 minutes after starting the phone I all of a sudden lose 4G and it goes to 1X. I reboot it goes back to 4G and 20 minutes later back to 1X. I am hoping the not registered yet message is due to maybe a screwed up sim card and hopefully the 4G issue as well. If anyone has any ideas at all please reply. Also will reflashing the phone rebuild that efs partition that stores the IMEI number? As I am under the impression that totally reflashing back to stock rebuilds all the phones partitions.
HERE IS ANOTHER CLUE
When I go into settings in 1X mode, if I turn airplane mode on and then off again a few seconds later I go back into 4G mode for a short while then it goes back to 1X. I am really hoping my sim card is to blame for this issue as I will get a new one today to test it out.
Do some research and look at the G2 method to restore IMEI. Use the hints of how to downgrade version by tot method in connecting G3. It can be done. Try to stay off of Verizon in mean time.

Check this thread for your IMEI issue...it may work for you too: http://forum.xda-developers.com/ver...-t3033445/post58915450?nocache=1#post58915450
Good luck
Thanks a lot for the help guys. I was at work all day so I didn't see that 2nd link or I would have tried it before I did what I actually did. I went to the local Verizon store and told the salesman that in trying to get my phone to be able to use a PS3 controller (which is the truth) me and my buddy downloaded software onto the phone to alter it so it would allow for the controller to work with the phone so I could play games with it. Again all true I just left out the name of the software and I handed the guy the phone after telling him how my Sim card seems to be whacked out and my IMEI is gone. He changed out the Sim card and that did indeed fix the phone not registered issue and also the 4G problem was gone too. I was going to leave well enough alone when he said while your phone will work fine it is showing up as an unsupported device on my computer, it is still within the 14 day exchange period do you want me to swap it out with a new phone? I said that we altered the phone, wouldn't I have to pay for a new phone as that voids my warranty no? He said well I see you are eligible for a discount and since you bought this LG G3 near Valentines day I can offer you a free LG G Tab 8.3 tablet, I will knock off the 10 dollars payment per month from another phone that you are owed a discount on and basically all you have to pay for is the 40 dollar activation fee and sign a 2 year contract for the 10 bucks a month that you really won't be paying since I am knocking it off of another phone for you. Do that and I will just wipe this phone again as it works fine and we can easily fix it and I can just set you up here with a replacement and you will be good to go. I couldn't believe it lol. So I walked out of there with a new LG G3 plus a free (not really free since it is 10 bucks a month but he took 10 bucks off of a different phone which would not have happened if I didn't go there today) LG G-tab tablet AND I TOLD THE TRUTH!!!! It probably doesn't hurt that I now have 8 devices attached to my account and send somewhere around 360-400 dollars a month to them lol.
Glad it worked out for you! Yep, I'm sure it doesn't hurt that you're a non-benefiting "shareholder".
I have the VK810.4G (Verizon LG G Pad 8.3) too.

Xperia 1 J8810 not working in USA

Hi everyone. Last month, I bought a network unlocked Xperia 1 J8110 from a UK vendor for use here in the US. It arrived in excellent physical condition and is from a reputable seller with thousands of phone sales, so not just some random person. I checked behind them, and this phone is for sure network unlocked (see attachment) and from what I've read online, it should work in the US. I've owned plenty of UK phones from other brands and they worked fine here.
The trouble is, I have not been able to get this thing to work with any carrier! I’ve now tried Ultra Mobile (T-Mobile’s network), AT&T, and now US Mobile (Verizon’s network). When I plug in a SIM card, the phone recognizes it and reboots. However, after going through the activation process, I never get any 3G, 4G, or SMS functionality. This is ironic as I have Verizon and T-Mobile towers literally behind my house.
The furthest I got was with AT&T, which received the welcome SMS and showed full bars on network signal. However, the phone kept asking me to “Sign in to network” like it does with WiFi but there was no way to do that. This was after doing the full activation with AT&T, giving them my IMEI, receiving a phone number, a confirmation email and everything. With Ultra, I got the welcome SMS from them but was never able to send my own or do calls in either direction. With US Mobile, it does literally nothing. Wi-Fi and Bluetooth work fine, and I’ve checked for obvious stuff like airplane mode being on.
I then figured I’d see if maybe flashing a version of the J8170 firmware would help. I used NewFlasher to flash the “J8170_Customized US_55.2.E.0.165-R7C” as downloaded off of XperiFirm, which was successful. But it’s made no difference. The only issue I’ve seen others report online is that VoLTE might not work with international phones, but I can’t make calls or send texts period.
Can anybody think of what the root of this problem might be? I’ve tried to figure this out for myself, but I’ve reached a dead end in my searching online, maybe I’m just not choosing the correct keywords. Please let me know which other screenshots or other information is required and I’ll post them. I will be so thankful for any input at all. I appreciate it.
