No 3G since FRF83

Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.

Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..

The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.

the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....

Thank you Good luck!

Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.

Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.

I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Same issue here.
Switching to WCDMA preferred doesn't work for me though.....any help is welcome

I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated

I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.

Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok

Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.

Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.

In need of instruction...

To give a back story on what I'm trying to accomplish, I'll explain my situation.
I work for Bell, in a retail store, the main reason I came to these forums was to find a way to re-flash phones in store to avoid having to doa what little stock we have of the phones. One of my colleagues from another location told me about the new update from Kies locking phones up at a ridiculous rate of 25%, so I'm trying to be pro-active about it.
Once I got in, I got a bit carried away with 2.2 software and what not. Now, i'm no expert, but I'm computer literate and made sense of most of the process, some extra guidance would be nice though.
Playing with the phones we have in store, I was able to flash every available software I could find on said phones, however a constant issue is found. I can not get a solid data connection. If I disable data, everything works fine, soon as I turn it back on, nothing happens.
Furthermore, I followed a thread regarding re-flashing everything back to Bell's stock settings and it didn't help me along at all.
I have done some searches, but i'm coming up dry. I know you've probably heard this hundreds of times and I'm sorry for being new to the process, some guidance towards this all would be great.

Can you elaborate more on this?
what do you mean by unable to get a solid data connection?
what kind of data connection are you referring to?
USB cable between phone to PC?
or Wifi data
or APN (3G) data?

not sure where you got that number from, but it's not that accurate
the reason for the ridiculous high amount of returned phones is due the Internal SD card problem that was found.
even under normal conditions if it gets formatted a lot or used a lot it seems to die faster than its Europe counterpart.
apparently on the Canadian version of the I9000 they use a bad batch of Flash Disk for the storage memory
there is a sticky Topic Poll about it.
it is NOT the ROM flash from Kies that are killing the units, just anything software that constantly access the internal SD can produce the same effect.
http://forum.xda-developers.com/showthread.php?t=793404
the rest of the returns you guys at Bell are seeing are due this other problem discussed here http://forum.xda-developers.com/showthread.php?t=775017
it can be reproduced, but you need the ideal conditions to do it.
it has to do with signal quality and tower availability

I'm referring to 3G connection. I have set up the APN, even tried different settings, all producing the same results.
In regards to your second reply, the phones I've seen at this location for DOA's have mostly because of a failure to fully turn on, the display won't show. I've experienced similar issues when a flash doesn't work properly, a re-flash fixes it. We started seeing this issue after samsung released the update. However, I'm not going to flash a customers phone to have them lose 3G connectivity, or open up other issues.
Basically, I'm looking for two things. Primarily a way to re-flash everything to work as if it were out of box, with the latest software update. Secondly, to be able to get a stable 3G connection on 2.2, everything else seems to work fine at this point.

i'm not even going to touch the 2.2 topic as it's not even released officially.
the current stable official flash is JH2, on JH2 3G should work properly (stable), another thing you can do is to go into the service menu using the secret codes (wiki) and make sure the proper 3G bands are selected for WCDMA
1900 and 850 should both have a start next to it
next check is the *#0011* to see if the towers keeps constantly changing
that's another reason for unstable 3G if the phone keeps jumping towers every few seconds
this is also related to the 2nd link i mentioned about people getting Comatose Syndrome on the phones, which locks up the phone, and they have to reset the phone to get the phone to work again.

I'm running JH2 currently, I ran *#2263# 850 and 1900 are available. Also, ran *#0011# both are available, ran a test on youtube it worked for 5 minutes.
Any ideas?
**Edit**
I lied, on the *#0011# it only shows 1900.

Get something straight
the update samsung released was JH2, and it is not causing the problems you've seen.
the problems with the symptoms described are after they were flashed by the Alpha & Beta versions of Froyos 2.2, which many of them do end up losing the 850 band, the band issue can be fixed with much work.
there have been at least 4 different leaks of froyo, each one bringing its own volume of chaos and bugs, the most dangerous 2 are JPH and JPK, one loses the IMEI / ESN number ID, the other one kills the internal SD

Since the I9000M and I9000 are hardware based bands, you should always have the 850 and 1900 bands for 3G
Many who have tried Froyo and back had come across the problem of losing the 850 band, mainly because the Froyo leaks were intended for the Korea test team running international I9000 devices
some times just by flashing the Firmware back to stock or Froyo betas doesn't actually activates the 850 band, even though it shows as selected in the Service Menue
if you go back to the Band Selection screen of the Service Menue, you should choose bands that are knowingly not available in canada, like say band 900 for example, and then go back again to the service menu, and band selection to only choose 850
once you can confirm 850 works, then you can select 1900 as well, and now both of the bands should be active permanently until some body else screws it up again.
using *#0011# and trying to call the voice mail are the fastest way to verify for line and for 3G on 850
you can also try the app speedtest from speedtest.net

[Q] Shows LTE, only works for a few minutes.

My phone used to work great on LTE, but one day it showed the LTE icon, but I couldn't get it to work. If I toggle airplane mode, then wait for LTE to connect it will work for a few minutes, but then go back to showing the LTE icon but not transferring any data. The phone works fine on cdma only, but I want the strong LTE I used to have. I've been dealing with it for over a month, and other people on sprint with different phones have strong LTE that works fine. I have updated the radio, tried AOSP and sense roms, updated radios, removed and inserted the sim card, flashed an RUU back to completely stock, updated profile and PRL.
On sense roms, I would occasionally get the message "Unable to establish a wireless data connection. LTE: EMM-65535, EHRPD: 65535"
Very frustrating, as 3g speeds in my area are awful, and everyone around me can take advantage of the faster LTE signal. Anyone else having this problem? Is there a solution, or is it a hardware issue?

Do you expericne this everywhere, or just in certain places? Are you "side by side" (i.e. in the same area) with your colleagues who have Sprint when they get LTE and you don't?
After nearly a year of strong LTE at our house, we rarely get LTE now and mostly 3G. This started about three months ago. When it first started, I only had an EVO 4G LTE, but we have also since gotten a One, and both phones behave the same. We live within 500 yards on the west side of the tower, according to SignalCheckPro. In fact, I can go outside and see the tower. When we do get LTE, SCP will sometimes indicate that the phone is connected to a tower futher away. If the phones have been inactive for awhile, they will initially show 4G, but quickly switch to 3G if we try any type network access (i.e. web, email, etc). If we go to the east side of that tower, we get strong LTE and 5-10 Mbps transfer speeds on both phones.
I reported this to Sprint a couple of months ago, and got a response that they were doing another phase of upgrades on that particular tower. I reported it again a couple of weeks ago, but got no response. There is a major retail business street on the east side of the tower, so Sprint may have re-focused the signal on the business corridor. I have also noted a couple of other towers in other areas of the city where I work that have this same highly directional behavior, and unfortnately, the places where I have to be are on the wrong side of the towers.
So, you could very well have a phone hardware issue, but it could also be Sprint. If you check other fourms, you will find similar reports of areas losing LTE after having it for some time. Which is why I asked if you can get LTE in some places, and not others. You might consider getting SignalCheckPro to see where you are in relation to the towers. IMO, Sprint's LTE network seems to be messed up in many places.

Yes, most my friends have sprint Iphone 5c's and a few android LTE Phones and live in my area. they all have strong LTE. I'm pretty sure it is a sim card/hardware issue because my phone has been completely stock and unrooted for about 2 weeks now, and the LTE Only worked for the first day. Unfortunately I got the phone on the day it was launched, so my warranty is gone. Unless there is some trick to get it to stay connected. :crying:

Yes I tried updating those, and updating the radios. Just wondering, when it was new it would always say the sim card was removed when it really wasn't. Is it possible that it has a faulty sim card? I'm pretty sure the sim card is only used for LTE.

VoLTE on At&t

So I spent an extensive amount of time about this whole VoLTE situation with this phone with both At&t and ASUS. My question is how do you know if you are actually utilizing the VoLTE connection?
I am able to make clear voice calls while browsing the internet or downloading an application. My speeds vary anywhere between 60 and 100 Mbps with no connectivity issues. The phone has no indicator of LTE connection but is constantly 4g++. Asus and at&t both stated that is the LTE connection. So I went into the phone settings via the image in this and it shows the VoLTE setting not toggled.
So the next question is, what indicator is there that this connection is NOT VoLTE other than this toggle? The speeds appear faster than Hspa+ but nobody I spoke to had the technological knowledge to be able to explain this. Also what speeds down and up is everyone else receiving?

From what I have read, this phone doesnt support VoLTE. And what worries me is that all the carriers are transitioning to VoLTE starting in 2020. Some are saying phone calls will no longer be possible on this phone. Which confuses me as it just released.

You can tell by making a voice call and seeing if the phone stays on 4G++ or drops to 2G/3G. I am 99% sure we will not get VoLTE on this phone. TMobile rep suggested tweeting TMobile on Twitter as the marketing team there might help, but I just don't care anymore. I'll stick with my pixel 2 xl for now.

Is ANOTHER thread on this necessary? Wtf? No volte. Not now, not ever. Get your money back. Asus are idiots for releasing this phone in us with no volte. 2020, no phone calls. Enjoy!

I know VoLTE is 100% possible on this phone, however not in the USA. It has something to do with the USA companies and At&t told me VoLTE is definitely a possibility as well as WiFi calling in the future but that has to be certified by the US companies. This phone supposedly works with WiFi calling as well as VoLTE in the European market as they don't have the same issues with the companies controlling the way it operates. I am moving to Norway on the 23rd but honestly the connection has been fantastic and I do like the phone quite a bit. During my phone calls I remained at 4g+ or ++ while surfing the web or watching Netflix with no issues during the call or the film itself.
I have messed around with it to see if there was anything that seemed off about it but so far it has worked just as well as My note 10+. Also the phone is operating on 4g so saying that it can't be used is silly. The 4g band will be around for quite some time while some companies like Verizon are removing 3g as it operates on the cdma versus gsm. At&t will continue 3g operations until 2022 and 4g will take years to completely phase out from 5g and by then another phone will replace the ROG 2.
I will however annotate how this phone operates on the European networks once I arrive. As per my previous post I can obtain 40mbps up to 100mbps which is definitely 4g speeds. 3g can not obtain those types of speeds. The bands available are key to the operating network for sure though. I think at&t seems to offer the best fit here in the USA.

I know VoLTE is 100% possible on this phone, however not in the USA. It has something to do with the USA companies and At&t told me VoLTE is definitely a possibility as well as WiFi calling in the future but that has to be certified by the US companies. This phone supposedly works with WiFi calling as well as VoLTE in the European market as they don't have the same issues with the companies controlling the way it operates. I am moving to Norway on the 23rd but honestly the connection has been fantastic and I do like the phone quite a bit. During my phone calls I remained at 4g+ or ++ while surfing the web or watching Netflix with no issues during the call or the film itself.
I have messed around with it to see if there was anything that seemed off about it but so far it has worked just as well as My note 10+. Also the phone is operating on 4g so saying that it can't be used is silly. The 4g band will be around for quite some time while some companies like Verizon are removing 3g as it operates on the cdma versus gsm. At&t will continue 3g operations until 2022 and 4g will take years to completely phase out from 5g and by then another phone will replace the ROG 2.

I am currently using this phone with AT&T. So should I be good for calls through 2020 and 2021? Reason I ask is because I literally just got it a week ago, and then read this news about the whole VoLTE thing and was just devastated thinking I have to now find a way to sell it and find a new phone.
Also, since I got the phone, I am only ever on H+ for the signal. I thought it was LTE capable? I came over from Verizon, so the H+ was something new to me. I know I am in a LTE area. Do I need to do something to activate it?

Was this a ported number? When I went from Verizon to at&t there was an issue when I ported the same number back to at&t. They were able to get it resolved by calling Verizon having them refresh the port and then re initiating the LTE from their end. And that was with my Samsung. I did speak to at&t again today about the LTE and they may have to make sure your Sim is "LTE" and also making sure they unlock it on their end. Supposedly the LTE and volte have to be activated from them. Also ensure you have the appropriate APN setting as sometimes with unlocked phones those setting do not carry over.

And the phone should be working fine until a minimum of 2022 even with 3g or H

I did bring the number over from Verizon. I may have to go in to AT&T to resolve that from what you're saying then.
Dealing with the APN setting, I am good with tech, but this part has me a tad confused. What should I be looking for on the phone? I see under APN, it says AT&T is selected. There are other options like tracfone, but I assume its fine then if it has AT&T selected?

Here is what at&t recommends for APN settings
https://www.att.com/esupport/article.html#!/wireless/KM1218306
And yes something about how Verizon and at&t handle it some things can get "hung up" in the system

I tried those APN settings and it seems to not work. The signal bar still shows a signal, but there is no longer a H or H+ sign. Hmmm

That's interesting, but I would recommend going to at&t and confirming that LTE is good to go on your phone. They can also verify nothing is stuck in the system and your appropriate APN settings

Can't add APNs - Therefore, almost no signal/service.

Hello,
I'm having a hell of a time with 90% of the day without signal or service on my XZ3.
Same SIM on my old XZ1 works fine (Sony Fan). Another SIM on XZ3 does not pick up signal either. There is some issue with XZ3.
I wanted to add more APNs, but I face this error.
https://ibb.co/3r8qb3M
Using this SIM on an XZ1, configures 3 APNs and I was able to add another one using APN type default. Signal picks up great on XZ1!
On XZ3, I only get 1 APN automatically and I'm not able to add more due to the error message.
Seems as my XZ3 has some problem with 2G/3G. The only time of the day I was able to pick up signal was 4G+.
I'm on latest firmware. Same situation happened on the previous firmware .672.
Any help?
Thanks!

This was so weird.
Downgraded to Android 9. I was able to edit and add APNs. Signal still has issues although I was getting 2G singal fine for a while.
Back to Android 10. APNs created were deleted and I can't add them back again receiving the same error. No 2G/3G.
Back to XZ1. Signal picks up by charm
How can XZ3 signal suck so much vs XZ1?

Did you do a fullwipe on the newest 10.0 stock firmware?

Yes. I tried full factory reset before downgrading to android 9 and then going back to 10.
I really don't know if APNs do the trick because XZ1 and now S10e and A30s before have great connectivity with just 1 APN.
Its the baseband. And Argentina may not have the best signal... but why XZ3 was picking 4G+ for a while and then literally dies. As if the antenna turns off and on...who knows.
Truth is. No Sony support, no way to talk with people that handles the firmware.

And what happens on a fresh fullwiped 10.0 ROM?
I sadly assume that you may have a defective hardware.
Oooor does your provider use a not supported frequency?
(But I doubt that, today 4G hardware supports almost every LTE frequency in the world.)

Fresh fully wiped experienced the same signal issue as before.
My H9436 supports all the bands the company does. Why would my old dual XZ1 would get signal so easy and the XZ3 won't? Its so frustrating...
For now I sadly think some kind of faulty hardware.
I will try again on July with June update in. I'm out of ideas.
I would love to be able to make tests to see on which bands is the signal picking up, maybe there are some which do not.
Or even more, when ot picks 4g I have over 100dbms of strength.
Thanks
