Having an issue with LTE on my Z3 D6603 after flashing 23.4.A.0.546.

My Z3 has a locked bootloader.

Taking advice from a couple of other threads, I downloaded this latest Customized US firmware using XperiFirm. Unpacked it using Flashtool, then generated the stock FTF, again using Flashtool. Excluded the two .ta files, as several sources advise.

I downloaded the latest flashable XZDualrecovery, as well as the latest SuperSU (2.46).

Using PRFCreator, I combined these three things into a pre-rooted FTF. I selected to include everything in the ROM (all check boxes checked).

I put the final image on my SD card, booted into TWRP, cleared cache, dalvik, and then flashed the new ROM. Cleared cache again after it was done. I did not clear data before I flashed.

After loading up the OS, after a while I noticed that it seemed like LTE wasn't really working. It would kind of just trickle data every now and then. Sometimes it would work at full speed but only for a few minutes. Sometimes websites would fail to load, sometimes not. For example, the app reddit is fun would be able to refresh the list, but clicking on most of them wouldn't load the external site. Tested a few sites randomly (not through the app), same problem.

All these issues immediately go away if I disable LTE or switch to wifi. I have confirmed that my APN settings are correct.

Yesterday I actually went back into TWRP and wiped system, data, cache and dalvik and re-flashed the same image again. Although it seems to be "better", the problem still seems to be present. Again, that problem seems to be that just sometimes, stuff won't load when connected to LTE, or load very slowly, or only after multiple attempts.

Does anyone have any networking troubleshooting tools that I might use to pinpoint what the problem is?

I'm considering that this may be a problem with the modem portion of the new image. I was thinking about flashing an older image (like 5.0.2) and testing again for the issue. After that, pending the results of the test, I might re-create a pre-rooted FTF with PRFCreator, excluding the modem from the final ROM. Anyone think this might be a valid possible solution to try?

Anyone had this problem before? anyone know of any troubleshooting steps I might take to discover at what point the network it failing? Some app you can recommend perhaps? I don't want to throw this back on my carrier unless I have to, it seems correlated to loading this new ROM.

Wipe cache and dalvik-cache in recovery.

---------- Post added at 07:18 PM ---------- Previous post was at 07:14 PM ----------

Me and another user have the same problem. He did factory reset and it didn't fix the problem at all. I reverted back to 5.0.2 and the speed was back to normal again. I am doing a full wipe, and then reinstall 5.1.1 to see if the problem goes away. I suspect it's the radio (which includes the baseband, from my understanding) portion of the image that is causing the problem. I would suggest making a flashable radio of 5.0.2, instead of excluding radio of 5.1.1. That was what people usually do for Nexsus phones. Unfortunately I do not know how to make a flashable zip.

On a side note, both of us are in the US, on straight talk At&T. What country are you in and which service are you using?
[Xperia Z3 General] jcsweat:
Cool, glad to see I'm not alone. Based on my test, I don't believe doing a full wipe and installing 5.1.1 again would fix the issue, as that's what I did yesterday and it hasn't alleviated the problem. But please, go ahead and let me know how it goes.

I'm unsure of how to make a flashable image that's just the modem. I wouldn't know which files in the decrypted fileset would make up the components of the modem. Now that I think about it, if I knew, then I could simply substitute the modem files in the 5.1.1 image for the modem files that came along with the 5.0.2 image. But I don't know enough to be able to do that. There may be other dependencies which make a simple replacement like that impossible, and I'm not about to brick my phone over this.

I'm also on Straight Talk in the US. I'm thinking more and more this is partially to blame on the carrier, even though based on your test it sounds like 5.0.2 still works fine. I got this feeling because I decided to look up my APN settings on straight talk's website, just to see if I got them right. The website actually reported that I should use some different APN settings than what I was using, but when I switched to the new APN, I had no data service at all.

For the record, I currently have a tracfone branded SIM using Straight Talk's service, and using the "tfdata" APN settings. I won't go into that full list of APN settings because you're probably familiar. The new APN that the website told me I should use has the APN as "RESELLER". This APN didn't give me any data service at all. I think this non-matching APN might be part of our problem. If you have time, please look up your phone number's APN settings according to ST's website and see if what they report you should be using works for you.

With doubt that my SIM card might be the issue, I've ordered a replacement SIM card from Straight Talk. For $6 and change, it's too cheap of an option not to explore. I'll follow up with an update after i get it. In the mean time, let me know if you figure anything else out.
[Xperia Z3 General] wngmv:
I did something horrible wrong, ended up having to reflash the oldest firmware and re-root my phone. After that, I upgraded directly to 5.1.1, meaning it's basically installed on a full wipe. And nope, it hasn't fixed the problem at all. I believe we need to either talk to Sony directly about this, or Straight Talk. I seriously wonder if any of that would be helpful.

I was always using the tfdata APN, and wasn't aware the other one. I tried both, and like you, I have very slow/no speed on tfdata, and no data (not even the LTE logo) with RESELLER.

I looked into the rtf file. First of all, I am not even close to an expert of Android. I just have used two nexus phones. On Nexus, the img file (the equivalent of rtf, I guess) would contain a file called "radio.img" which would contain the radio. Here it is obviously not the case. I see there is an option to flash radio only in flashtool, but I do not really understand how this works. Maybe I'll PM one of the mods here or someone who made a guide. They would have more knowledge of this I would assume.

But this sucks. the worst part, probably is that not knowing going forward if this would get fixed at all.

PS:

There is a fix detailed here,

http://forums.androidcentral.com/sony-xperia-z3/468763-xperia-z3-losing-data-connection.html

I tried it and didn't fix anything for me. I am back to 5.0.2.

Recovery bootloop?

Anyone having issues after flashing D6603_23.4.A.0.546_Customized_US_SuperSU_XZDR2.8.2 1 ?

I flashed and am now in a recovery bootloop that puts me straight to the default recovery (Philz). Whenever I try to flash anything I get a bunch of "cannot mount" type of errors and similar.

I am wondering if I had a bad download/transfer to the phone.

Would appreciate it if anyone has any thoughts, or if they've successfully flashed this.
[Xperia Z3 General] x-geo:
what happen if i flash this zip in a locked bootloader z3?
[Xperia Z3 General] DJ BlackEagle:
Nothing, only prerooted android.

You can flash it.

But you must have rooted already your z3. This firmwares for locked bootloader.

But the stupid dry restoration, it's didn't needed on locked bootloader. It's not clever.

Use a firmware without drm restoration. Xposed is easy to flash.

My Z3 is 6643, which one should I install? I'm on a non-rooted 5.1 right now, do I have to roll back to KK, install a recovery and then install this ROM, or can I flash this straight from flashtool ?
[Xperia Z3 General] DJ BlackEagle:
You must rollback to kk. Then root it / flash recovery and then use a prerooted 5.1.1 firmware.

Don't use the kingroot rooting tool.
[Xperia Z3 General] slinson:
it is the same...once you download it from that link and the file name looks like what I mentioned above
[Xperia Z3 General] Maksvr:
I experienced an extreme amount of suspend_backoff wakelocks after updating to pre-rooted 5.1.1 (both US and UK versions), as a result the battery drained within a day (the device was awake 100% of the time). As it is very difficult to find the culprit for this wakelock and there is a lot of misinformation on the internet I almost reverted back to 5.0.2.

Today however I found that the option "queue background data" in the Power management menu caused this (perhaps in conjunction with some aggressive removal of Sony stuff in TiBackup I did). So if anyone is experiencing the same issue, try disabling "queue background data" (this option is off by default by the way!).
[Xperia Z3 General] DJ BlackEagle:
I think, you mean it's default on. Because, why disable it, if it's default is off. ☺

By a way, it's default on this option.
[Xperia Z3 General] Maksvr:
I thought it was off by default, and I turned it on myself, but I'm not sure so you may be right. Is no one else experiencing these wakelocks?

[Xperia Z3 General] jcsweat:
Hey, following up on this issue. Getting a replacement SIM card from Straight Talk has fixed this issue for me. To be clear, I'm currently running firmware version 23.4.A.0.546, pre-rooted with flashable SuperSU 2.46 using PRFCreator, and using XZDualRecovery 2.8.21 recovery.

I bought another SIM from Straight Talk for $6 and change. I received it and transferred my existing service to the new SIM using their online tools. Very easy process. Next, I:

turned off my phone

removed the old SIM card

installed the new SIM card

turned on the phone, let it boot normally

Per Straight Talk's instructions, I confirmed I had signal and made a call. Everything worked fine.

Deleted all old APN entries

Set up new "RESELLER" APN - took about 30 seconds before I had any data at all after saving and applying

Turned on LTE data

rebooted phone

Now my LTE data works as expected and with none of the problems I mentioned before. Your mileage may vary, but if you're still having this issue, I recommend getting a new SIM card from ST, setting it up with "RESELLER" APN settings, and see if that resolves the issue.

Hi,

I'm trying to understand how to make it work with the DRM patch (http://xdaforums.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672).

What I know :

DRM Patch need KK (23.0.1.A.77) to be applied (source)

To get root and install recovery, I need GIEFROOT which uses another version of KK (23.0.A.2.93) (source)

Then, I will be able to install that pre-rooted rom

Can someone explain me in what order I need to do this ?

If I install the .93 first to get root and recovery, the DRM patch procedure will make me lost my root and recovery.

In other way, if I install the .77 first to apply the DRM patch, would I be able to downgrade later to .93 to get root and recovery in order to install that pre-rooted rom ?

And, after all, is this pre-rooted rom will be compatible with the DRM patch ?

I'm really sorry for these questions. Maybe you'll think it's so easy but I can assure you that I've done a lot of search on XDA and other and I couldn't find any clear answer to them... so... please help me ;)
[Xperia Z3 General] heywheelie:
download the stock firmware using xperifirm (available here on the xda forums) and create and flash it with flashtool. Everything you need to know is clearly set out in this post http://xdaforums.com/z3-compact/general/list-stock-firmwares-d5803-d5833-t2906706
[Xperia Z3 General] Richy99:
if you have unlocked the bootloader then you just need to install a pre-rooted rom via a recovery

I assume you have unlocked the bootloader?
[Xperia Z3 General] lodep59:
Yes I have !

But I've also lost my DRM keys (:rolleyes:), that's why I need the DRM patch.

If I only install the pre-rooted rom I will not have the DRM patch and, as I understand, if I only flash the zip of the DRM patch (after the rom's zip) it will not work because that patch uses a TA partition (based on the 77 firmware).

So, as I said, I think I have to downgrade to .77 (for DRM), then downgrade again to .93 (for root and recovery) and then install the pre-rooted rom and the DRM patch... But will it work ?
