LTE on a C6602 Firmware - Xperia Z Q&A, Help & Troubleshooting

Hi All, Long time listener, first time caller, big fan of this place.
I have a T-Mobile Xperia Z, originally an LTE phone. For the sheer purpose of preference (and 1 bug) I switched over to a C6602 firmware. It gets the job done speed wise, and now I can do MMS (which I couldn't do on LTE, never figured that one out). So I have been quite happy with it. Today I made some changes in my status bar toggles (quick settings) and when I went to check it I had added the LTE icon. Out of sheer curiousity before removing it, I clicked it on, and low and behold, my phone switched over to LTE mode and I am surfing. (I base this solely on the status bar icon)
What gives, this firmware isn't for LTE, says just about every page talking about that firmware, but yet it says LTE and I am surfing at a nice speed. Am I to assume I am still rocking the H+ or am I really on LTE, despite the icon. Any way to find out for sure.
I checked *#*#4636#*#* but that's not real conclusive because I don't know exactly what I am reading, because under GSM Service, it says In Service, but under network type, it says LTE.
Have I discovered something, or have I been fooled. Couldn't find the answer, so I thought I would ask ???
Thanks in advance, sorry I talk to so much, just trying to be descriptive.

Hmmm, actually I found another page about the same thing, apparently it can.

Nah! That thread you're quoting.is for enabling (unlocking) LTE capability in a 6602 device (by software or by hardware recoding as the device is not LTE capable, out of the box)... What you're experiencing is LTE on a 6603 in a LTE environment, with a LTE micro-SIM (hence, LTE capable device), in spite of running a HSPA ROM (meant for a 6602 device). It's like chalk and cheese...different lines of thought....

Interesting, thanks for sharing the how and why. For that briefest of moments, I thought I had stumbled on to something.

[Q] Bionic on GSM in India - Tata Docmo

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!
Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.
Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?
I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!

[Q] HELP UK model with serious signal issues on ATT in the USA

Hi all, well my One arrived from the UK today.. As I feared it does not have the ATT LTE bands that PDAbd.net suggested it had, bummer, but I can live with HSDPA... Set up the phone, it asks me to select the operator I am unsing, with ATT as the first choice... all goes well.. I load it up and initial impressions... WOW.. what a great phone.
BUT and and very BIG BUT.... the signal is terrible... bouncing from no signal to 2 bars and displaying H one minute, 3G the next and then E...
Driving down a notorious road it drops the call at least half a mile before typical and doesn't pick it up again until even later..
Does anyone know if there are any setting I can adjust to optimize to ATT?
I really do not want to put it is back in the box, but unless someone has a suggestion for me, I have no choice...
Help!!
Many thanks,
Nick
A quick question. Where did you get your HTC One? And have you used any other HTC Phones before and got good signal with it?

Hi There,
I bought it in the UK. It was a legitimate HTC supplier and an unlocked model 801n.
I have used a couple HTC phones in the past:
ATT 8X - worked well (at least as far as signal was concerned, but that was the ATT model)
I also had a Verizon Incredible, but since that is a different provider, I am ignoring it.
Other phones I have right now adn tested in the same location with the same SIM:
1. ATT - Galaxy note 2 - good signal no issues
2. ATT LG Optimus G - Good signal no issues
3. ATT Iphone 5 Good signal no issues
4. ATT Nokia 920 - good signal no issues
5. Blackberry Z10 - unbelievably good signal - no issues - Unlocked ATT bands, not ATT branded (Purchased from Expansys USA)
This is why I am wondering whether it is some kind of optimization issue. I cannot believe HTC could have made such a mistake in design. Also, if I switch to GSM only, I have full bars.... It is only on 3G and HSDPA that the signal is poor and the display oscillates between 3G and H
Any advice?
Many thanks,
Nick
Are you rooted? The solution is disabling fast dormancy on HTC One. New HTC devices enables fast dormancy by default which affects & weakens signal strength on networks that doesn't support it yet. If not I am not aware of any ways to disable it without root yet. I'll update you if I find one.
On UK almost all networks do support fast dormancy already except for Three UK so that maybe the reason why it's enabled by default in the US however I am not aware of the implementation of network carriers there sorry.

No I am not rooted - what will I lose if I root it? Do you know of a link to a simple thread with rooting instructions and how to disable the fast dormancy? I am not super experienced with Android yet
Does anyone know whether ATT supports fast dormancy of not?
Also, I have been led to believe that the One supports a number of carrier frequencies, but they only enable those for the specific region it is sold in. Do you know if there is a way to enable the other frequencies? Or is this just an unfounded rumor? Also, do you know if there is a way to check which LTE band the phone I have is equipped with - Not an on-line reference, but a way to find it on the phone?
Many thanks!!
Your warranty if you mess something in the software's side like bricking your phone & OTA updates. But you'll be able to update anyways just by directly flashing on the phone.
Anyways here's a noob proof app to rooting. Please do some research first before going so you'll not mess this up.

Check this regarding what is Fast Dormancy and tell us if it works(probably NOT (it works only to samsung phones) but it is easy to try) http://androidforums.com/samsung-galaxy-s2-international/674208-fast-dormancy-in-nutshell.html
"To turn FD on/off enter *#9900# in the dialler to get into the SysDump screen then select the Fast Dormancy option"
You mind sharing the link if they have stock? Good luck with the signal issue.

I had a friend with an international GS2 with the same problem. Constantly bounced from HSPA+ to 3G to EDGE to no signal. I'm 99% sure that the issue is network settings, you likely need to check SIM card, data plan provisioning, APNs, etc.

Hey, thanks - Do you know what settings I should use? I have an LTE provisioned SIM card...I assume that should be ok, since the phone is LTE enabled, just wrong bands? I have tried with Auto LTE on and of - I currently have it on GSM/WCDMA - it has been working better the past day, but it is still not right..
The SIM works perfectly in the Note 2, Optimus G etc. So I am wondering whether I need to look at the APN or something like that, but I do not know what the best settings should be. Anyone have this info?
Many thanks,
Nick

APN shouldn't affect your mobile signal reception. It's just made for cellular data profiling. So you are able to connect to the internet.
How about try setting your network selection mode to manual and just select the top most usable network there?
Interesting... I am in Korea right now and have great signal... no issues at all. However, my data indicator is still bouncing between H and 3G, so that is very strange...
Despite the indicated low signal and bouncing data connection type indicator, the phone is working well, have not dropped a call recently and excellent phone call quality...
NO LTE connection in Korea though.. I assume that is probably due to ATT not having a LTE roaming data service agreement here? I believe my phone has at least one LTE band that it supported here.
Have fun..
Nick
I think u should talk to att people may be they can help? With the signal issue or the data connection issues!
Please let us know once u figure it out

Here are the APN's that I use, and everything works as it should - http://forum.xda-developers.com/showthread.php?t=2236735. I've never flashed anything other then what the ROM(s) instructions say - and as always it's best to start clean. Enter as it appears on that thread, select it, and reboot. Not trying to state the obvious or insult you, but also make sure you select "LTE (preferred)/WCDMA/GSM" for network mode in settings.
What I've learned browsing other threads about 4G (or HSPA+) is that it only kicks on when there is data to transfer, so if you are not uploading/downloading then it will most likely show as 3G or maybe nothing at all in you status bar, but should change once you launch an app/service that uses data. It will remain 3G if only using voice.
I will try and confirm this, but where I live it switches to LTE rather quickly. I have noticed a time or two where my friends 4G only phone has it and mine does as well. Noticed yesterday where H+ kicked in when loading a podcast, and when it was done the H+ disappeared.
Hope this helps.

Hmm im reflashing 4.3 ill check it out in a bright area

Showing "3G" instead of "H" in status bar, but still HSPA speeds

For a while now (I'm not sure exactly when it started, maybe a week ago or so) my Nexus 6 has only been showing me "3G" in the status bar. It used to show "H" most of the time.
Didn't think much about it at first, but now I was wondering because I had a Moto X (2014) before and that phone *always* showed H and practically never 3G.
So I opened the *#*#4636#*#* menu and checked under Phone Information, there it says "UMTS" under "Network type". I think it used to be "HSPA" under that item if I was connected via HSPA.
At first I thought maybe my carrier had some kind of network problem, so I did a speed test for the heck of it. The weird thing is, I'm getting speeds of 7 Mbit/s down and 1 Mbit/s up. These are HSPA speeds. So I must be connected via HSPA after all?!
It's not a problem per se since I get the speeds I want, but I'm still a little anxious something might be wrong with my Nexus 6.
Anyone know if they changed the behavior of the indicator in the status bar or something? Or is this related to some setting that I'm not aware of?
A friend of mine with a Nexus 5 on the same carrier as me is still getting the "H" in the status bar (albeit living a few hundred km away).
Nexus 6, completely stock and unrooted.
I have LTE deactivated by the way, because even though we do get LTE coverage here, my plan doesn't cover LTE speeds. If I activate LTE, the phone changes to the LTE network. 2G (EDGE) is also working and displayed correctly.
Are you on Lollipop or Marshmallow? Quick story: I only get HSPA at school and it used to say H/H+ when I was on Lollipop. After updating to 6.0 it says 3G now. If you're on Marshmallow I think it's 100% normal and nothing to worry about.

I am on Marshmallow actually. Weird thing, though, is that my friend with his Nexus 5 on Marshmallow still sees H. Maybe they changed something just on the Nexus 6, but why would they? Plus on another forum someone said they still see "H" on their Nexus 6. I don't see it at all anymore.

I still see H, but very rarely. Maybe 3G is the new H+? So it goes E, H, 3G, then LTE now instead of E, H, H+, LTE like it used to?
When it says H in the status bar, it will say HSPA in settings > about phone.
When it says 3G in status bar, it will say UMTS.
3G will download up to 7.2 Mbps.
HSPA+ will do 21 Mbps
DC-HSPA will do 42 (21 on each channel) though I don't think we support this..

I see. I thought they were just using a new symbol for HSPA/HSPA+ in Marshmallow. I never saw 3G in my status bar on Lollipop. It was always H/H+/LTE.
just read the title to your thread.. just so that you know, H, or hspa, is 3G.
and speeds of 7mb /1mb are very slow hspa speeds, but normal 3G speeds. on H, and on tmo, i can see speeds up to 21mbps. and on H+, i can see speeds up to about 42mbps.
I've noticed something similar. Almost like the signal bar and type is sticking. Putting it into airplane mode often switches it back to how it used to be.
I also find the signal bars seem to be sticking too. Where I normally get full signal it sometimes shows lower (and at multiple locations).
No idea why, only since marshmallow.

I sew 3G occasionally. It's rare because usually where there is 3G, there is HSPA.

Technically, HSPA is 3.5 G.. It's an evolution of 3G, but as per my previous post, they are indicated differently both in the status bar and about phone.
OP is not seeing HSPA of it shows UMTS in about phone.

I do know that. I'm aware of all the intricacies of these more or less arbitrary names. Though I thought non-HSPA 3G wouldn't give you more than 384 kbit/s down, while HSDPA (no +) would give you up to 7 Mbit/s. That's what wikipedia and quite a few other sources say anyway. But what Google or whatever manufacturer shows you as "3G" and "H" and "H+" could be something different entirely, so...
The question is more or less, what does stock Android mean when it says "3G" and "H" in the status bar. It used to and still seems to be 3G == UMTS and H == HSPA. So in essence, I'm wondering why my Nexus 6 is never showing me any HSPA anywhere anymore. Is it a software issue (i.e. Android not showing the correct value, or Android not making the hardware connect to HSPA), a hardware issue (broken Nexus 6) or a carrier issue. The latter seems unlikely, at least in a general sense, since my friend on the same carrier still sees "H" in the status bar.
This isn't about how fast the network is or should be, but rather just if I'm looking at a hardware fault that I should be concerned about, since it just changed all of a sudden.

I've had that too. My signal indicator stuck at 0 bars indefinitely. Anywhere I moved it kept showing 0 bars, even at places that always have good reception. But I could still make calls and use data just fine. Airplane mode fixed that for me as well when I had it.
I've been through several reboots and Airplane mode switches so far though and HSPA (or rather the "H" in the status bar) isn't coming back for me.
Check your mobile data settings to make sure you're not limiting anything and check your apn too.. It's unlikely hardware.
Speed is useful. Your speeds are much too low to be HSPA so it's indicative that you really are connecting as 3G only.
Out of curiosity, for those that are seeing 3G appear at the top, you guys on T-Mobile? I started noticing this too as of yesterday. I work in a large commercial building where I can't get LTE yet (until at least T-Mobile flips the B12 switch) and typically I get HSPA(+). I thought it was coincidence that I started seeing 3G as of yesterday as there is some tower maintenance going on (at least that's what a T-Mobile RF engineer told me)
My phone is currently on 6.0 build MRA58K.
On a side note, has anybody else noticed their signal being worse since the 6.0 OTA? I'm getting at least -10dBm worse now vs my Nexus 7 LTE (running 5.1)

I have also noticed a weaker signal and more time without signal (went from 0-2% on Lollipop to 9%+ according to the battery stats). I flashed the factory image (too impatient for OTA's). I haven't tried any of the older radios yet.

I did already check mobile data settings and switched everything around in there, but no change. APN settings too. I haven't changed anything in either of those places anyway so an issue with them seems unlikely to me.
In my case, speeds aren't really useful, because my carrier limits them softwarewise to the speeds I have (7 Mbit/s). So even if I turn on LTE (have it switched off normally) I only get 7 Mbit/s - but still the LTE signal indicator.
I doubt it's a carrier issue since my friend still sees the H, you doubt it's a phone issue, so that just leaves us with a software issue

You might want to check with T-Mobile about band12 support for the Nexus6 on Marshmallow with the stock radio. There have been reports that T-Mobile had band12 support disabled on the Nexus6 unified Marshmallow build.
Maybe they already flipped the B12 switch, and that has left you with just 3g ?

Band 12 works on Marshmallow, I noticed it the other day when I was downtown in an area that had coverage, I'm just waiting on them to flip the switch in my area.

What kind of SIM do you have band12 working on Marshmallow?
Band12 even just for data is for sure disabled under Marshmallow with a Project Fi SIM. Didn't use to be.
If band12 and T-Mobile VoLTE work with Marshmallow using a T-Mobile SIM, that is great news and I hope they will be able to get the 6p and 5x also to work on band12, and soon.
Project Fi, at least, is in a bit of a pickle over this issue, since they do not and will not use T-Mobile's proprietary VoLTE while on band12, and T-Mobile is refusing access to band12 without that certification.

I'm using a T-Mobile sim. The Nexus 6 hardware was certified to work through T-Mobile, which I'm guessing why B12, VoLTE, & WiFi calling work on this phone.
I don't know what the case is with the Nexus 5x or 6p, as those are being sold through Google only, where as you could purchase the Nexus 6 through T-Mobile.

How do you know that? Are you privy to the MVNO agreement between T-Mobile and Project Fi? That is not the same thing as TMO's certification requirement for devices using a T-Mobile SIM.
All we know with any certainty is that Band 12 data connections used to work for Project Fi users under 5.1.1, but do not work for those running Marshmallow today. We don't know why. It could be that "T-Mobile is refusing access" contractually, as you claim. Or it could be a technical issue that broke something in the new radio.
We do know that T-Mobile is refusing access to band12 data unless the device also using T-Mobile VoLTE, because that has been said both by T-Mobile and acknowledged on the Project Fi support boards.
You are technically correct though that we do not know for sure if that is why Project Fi users no longer get band12 data access with Marshmallow.
We also don't know it that is why neither the N5x nor the 6p get band12, even with a T-Mobile SIM in, yet. That might be some certification issue, despite press reports about T-Mobile requiring it's removal.
I am glad it is working on your N6 with your T-Mobile SIM in place. I hope it will work on mine with my T-Mobile prepaid SIM, too.
Some Project Fi users are claiming that as of Marshmallow, Fi should no longer claim that Fi users have the exact same coverage on the T-Mobile network as T-Mobile customers, since they don't any longer.

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 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?

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
