I am having a really weird issue I'm hoping someone can help me out with. I was on 4.1.2 Clean ROM which was working great. I wanted to move to 4.3 Clean ROM (8.1 Core Edition). I did the upgrade and then flashed my modem to ML1 both via TWRP.
The ROM setup fine and ran great. However the first time I did a reboot, the phone gets stuck at the Samsung Galaxy S3 logo and never goes anywhere. I left it sit there for 30 minutes and it was hard locked. Only a battery pull would reset it. Through numerous reboots/pulls, the same thing would happen. I tried wiping Dalvik and Cache in TWRP and fixing permissions, to no avail. Reinstalling Clean ROM 8.1 via TWRP without formatting data did not fix the issue either. The only way to get my phone back up and running was a complete wipe and reinstalling from scratch. Then as soon as I reboot the first time, the issue comes back. I've tested this on a clean install - letting the phone go through the initial setup process but not installing or updating any apps - and it still happens.
So I moved on to try AllianceROM build 22, also a 4.3 build and wiped to do a clean install. No matter what options I choose in the setup, the same problem happens. Interestingly in AllianceROM I always get a acore process has failed error on the first boot.
Then I went to download the Knox-free rooted version of stock 4.3 available from Scott's website. I have the same issue with this. Also a wipe with clean install.
It's obvious there is something my phone doesn't like about moving from 4.1.2 to 4.3. In total, I have probably installed three different ROM's about 20 times now after the past couple days.
I've searched about this problem extensively and the only thing I found is a thread for the AT&T S3 that talks about this exact issue, and using Odin to go to stock 4.3 and loading a custom ROM to fix the issue. But I am under the impression that a 100% stock 4.3 will lock my bootloader.
What I plan to do next is use Odin to flash a stock 4.1.2, then go through the process of moving to a custom 4.3 ROM again.
If anyone knows of a tar'd version of 4.3 that won't lock my bootloader, I would be grateful!
If anyone knows of a different way to fix my problem, I would be grateful for that too!
Well I think I can declare victory. My phone is running Clean Rom 8.1 CE and has survived a reboot after every app install for a total of 15 so far.
As it turns out, I think being on TWRP 2.5 and trying to upgrade to Android 4.3 was the issue. Before I went the route of flashing a stock 4.1.2 release, I thought to check if my version of TWRP was the latest, and it was not. I flashed TWRP 2.7, and did a complete wipe and clean install of Clean Rom 8.1 CE, and it's running like a champ.
I know, I know...the install guide on most every ROM says to use the latest version of your recovery - until now I thought that was a "recommendation" or "best practice" and not a hard requirement. Turns out, at least for me, that it is very much a hard requirement. In reading the release notes for TWRP 2.6 and 2.7, they both appear to implement things specifically for Android 4.3 or 4.4.
Hopefully this info helps someone who may be having the same issue.
Guys, I got the OTA to android 5.0.2 about a week back, but I'm tired of the poor performance. Nova 3 is now unplayable at parts where transparency is used. So, I was thinking to revert back to KitKat 4.4.4.
>>Will the performance improve after the next update, i.e., 5.1??<<
The dilemma I'm facing now, is to whether flash back to stock KitKat 4.4.4, or to flash cyanogenmod 11 using cwm recovery. I also want to know which one of the two will be easier and less problematic.
Thank you.

OK, problem solved.
I installed cm11 using philz recovery. Now, the phone is blazing fast!
Did not downgrade to stock 4.4.4. Instead to cm11 4.4.4.
Hi guys,
My girlfriend purchased a brand new Xperia Z3 D6653 not too long ago (about 2 months ago?). I flashed the 5.1.1 pre-rooted firmware for her and it's working fine and all but it does a random reboot every day or so, at random times, with random applications.
I have tried 2 different pre-rooted 5.1.1 firmwares already (yes, the correct model D6653 as well) and it still does it. The System Incident reports don't really say much (in fact you only see details about when it crashed, nothing else), and it seems like Google Play Services is the only thing mentioned in the Application Report.
The same thing also happened (more frequently) when she was on the 5.0 pre-rooted firmware. I'm not sure why, I haven't unlocked the bootloader or anything, it's just stock pre-rooted ROM, that's it. I haven't flashed any other ROMs other than the official pre-rooted ones.
Furthermore, before I flashed the 5.0 and 5.1 firmware for her, the phone came with Android 4.4.4. She used it for a month and reported several crashes as well, so that's with the original factory firmware, unrooted, unmodified etc.
She doesn't run any dodgy or random apps, she's just a typical girl that use Facebook and texting, that's pretty much it. I've done a lot of research on this issue and it seems to be quite common, however there isn't really a solution to this. The same apps she currently use never caused any issues on her older phones.
Also in case anyone asks, the only reason I flashed the pre-rooted 5.1.1 firmware for her is because it makes it easier for me to manage her phone (with Teamviewer, you can remote into the phone as long as it's rooted). Also, I get to backup her phone and do tests etc, makes it easier for me.
Also, I'm not using any custom kernels or overclocking the CPU etc. Everything is just stock but rooted.
Could this be caused by a hardware fault in the phone? I'm not sure what else I can do and would appreciate some suggestions.
Nobody have this issue??
Well, how about you try to flash a full, clean, stock ROM, don't root it, don't install any unnecessary app and see where it goes? If the issue persists, try getting a logcat from the phone and we can take a look at it. If it works fine after returning to stock, there might be a problem with the ROM or some apps you are using.
If it really is Gapps that are causing all the trouble, go to APKMirror and download the latest apps available (Play Services, etc) and see where it goes.
As mentioned already, prior to flashing anything, my girlfriend was running a completely stock, factory version of the phone. It came with Android 4.4.
I could flash a completely stock 5.1 ROM but was hoping that someone would share their experiences or a potential solution to this, considering this is quite commonly asked. I would also like to avoid doing this if possible, because if I were to go back to rooting the device, I'd have to downgrade to v4.4 pre-rooted, then flash to 5.1 rooted with custom recovery. It's just a lot of work for a simple testing that could be answered by others if possible.
Anyway, she didn't have any apps installed other than Facebook and Whatsapp, that's it. I might test with GAPPS and see how it goes, but I thought I'd ask here in case someone knows it's definitely a hardware issue or something else.
i would definitely give a pure stock 5.1.1 a go. I used to get the random reboots on the previous versions but i no longer have such issue.. Make sure you do a clean wipe and do it a few times.
Hi all, it's been a while but I thought I'd post an update and share what I've found/learned so far....
Basically, I'm still getting the frequent random reboots. I've tried reflashing the ROM and also tested out the latest .232 pre-rooted stock ROM, still getting the same issue. I've noticed that other than Google Play Services, sometimes Gapps will crash as well. But most of the time, there's nothing reported in the system or application crash logs. I've tested with everything running as stock, no additional apps installed. I then decided to flash the Minimal GAPPS 5.1.x and that sort of made the phone a bit more stable, but still reboots randomly every now and then.
Later on, I decided to try a custom ROM that still works on a locked bootloader. I found this here:
http://forum.xda-developers.com/z3/development/d6603-23-1-1-28-t3102271
The chef has provided a .232 firmware for you to flash in recovery, as well as the ROM base for the D6603 model. Mine is a D6653, but luckily the chef has also provided a D6653 patch for you to flash as well. I've flashed the ROM like so:
1. Wipe everything except my external microSD in TWRP. So basically, wipe system, data, cache, dalvik, internal storage etc.
2. Install .232 firmware.
3. Install v10.5
4. Install v12.0
5. Install D6653 v5 patch
It boots up fine but after using it for a while, I still get the random reboots. What's interesting is that I've also tried without flashing the D6653 patch, which essentially means I'm running just the D6603 base ROM on my D6653. It works, but still crashes as well. I just found it quite surprising that a D6653 could run a D6603 ROM, but it does make sense considering the main differences is just the baseband/frequencies.
Anyway, I later on decided to flash the pure 5.1.1 stock ROM, still getting the crash. Again, everything is tested on pure stock, no additional apps etc installed.
I'm starting to think perhaps this is a hardware issue on my phone?? I noticed that sometimes, my screen will show a bit of tearing and then it'll crash not long after. BUT, I also know that as soon as gapps or google play services crash, the phone will crash not long after as well.....
In fact, I later on used Titanium Backup to convert Google Play Services from a System to a User app, the phone will just boot into the lockscreen and then restart every time. This is a bit ridiculous because I've done this several times on other phones before and they never had such an issue. Of course, I'm not saying I always run Google Play Services as a User app, but that was just for testing and I honestly don't think it should cause a bootloop just because of that. I've also cleared dalvik and cache by the way, so it doesn't make sense that the phone boots into the lockscreen and then just restarts randomly.
I haven't tried uninstalling Google Play Services completely, but at this point I'm back to square one as I've exhausted pretty much all my options and it's been a complete waste of time. I'm beginning to hate this phone more and more. The only thing left is to unlock bootloader and play with other custom ROMs. But yeah, flashing the .232 firmware didn't fix it, AND flashing pure stock 5.1.1 Android didn't fix it either...
Just wondering if others have the same issue and any ideas what could be causing it? If I provide some Logcat logs, would someone be kind enough to look into this for me?
Update:
I'm still getting the random reboots and I think it's very likely to be hardware related. But sometimes also a bit related to software, specifically with Google Play services. I've had more time to test out a few things since my last update, they are as follows:
- Tested complete stock 4.4 ROM without root. Still crashes every now and then, but not as much compared to 5.0 and 6.0 (doesn't matter if it's stock or custom ROM).
- Finally gave in and unlocked bootloader (backed up my DRM keys of course). I thought perhaps that the stock Sony roms (and even the stock-based Sony custom roms) have issues for some reason. They are all the same base, so I thought I'd do a fair test by trying a completely different based rom, such as AOSP. I've used CM 1.2.1 nightly here:
forum.xda-developers.com/z3/development/rom-cyanogenmod-12-nightlies-xperia-z3-t3010201/page117
And yes, I know that nightly have bugs, but the nightly build as of 2016-03-03 seemed pretty stable according to most users. I've tried various other AOSP based roms and stock based Sony roms (for unlocked bootloaders) and they all produce crashes.
I've flashed custom kernels as well and updated my recovery to TWRP 3.0, but all the same results. On all of the custom ROMs I've flashed, the only thing I've done was setup my Google account (so I have my contacts and Gmail) and that was it. No other apps installed. I wanted to limit the environment down to just the stock setup of the ROM itself, as this helps me rule out any potential bugs caused by 3rd party apps.
Having done all of the above and still resulting in crashes, it's safe to assume that this is most likely unrelated to the software, but hardware. I've noticed that sometimes when I scroll a page too fast and move it up and down with my thumb, the screen will freeze and restart.
However, sometimes I will get crashes related to Google Play Services. Anything that relies on Google Play Services will crash randomly. If you re-open the apps, it just crashes again. If you force stop the app and open it, still crashes. The ONLY fix is to restart the phone. I have tried flashing different GaPPs, starting with the pico and nano versions, as well as the ones recommended by the ROM chefs. Still the same result.
So the conclusion is, I haven't really gotten anywhere with this annoying issue. There's definitely an issue with the phone somewhere, maybe a bit of software related, but mostly hardware.
Hi, I'm having issues with my Xperia E3 running slow, especially when typing and scrolling. Im rooted with no custom roms, up to date firmware. I've factory reset my phone several times and while it does running better, i'll add a few apps and link most things to SD but not move them to SD. Over the course of the week it'll start running slow again. I'll clear cache and other unnecessary things that may slow it down but nothing seems to work. Is there any way to speed it up whether it be using a custom rom or some other trickery. Thanks.
Update your kernel to one with ZRAM support, so you will use better your 1gb of RAM.
Try vinay's kernel.
