Bootloop on stock rom - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Have a locked Z4 tab so totally vanilla, was working fine minus streaming video was lagging which could well be network thought I'd reboot though to make sure and now it won't boot up.
It is encrypted so enter pattern when prompted and get o2 branded startup screen for a minute then led flash red and reboots.
Any ideas before I am forced to try factory reset? Really don't want to wipe it if at all possible.

Q: WT19a random wifi disconnect and Custom ROM flashing problem

Hi!
I have 2 problems with my lww.
The first one is the wifi. It disconnects at random times even having the wifi config to always on and using the wifi high performance wigdet. I go then to the wifi list and i can't see my home network. I have to press scan a couple of times to make it appear again. Is there any fix for that?
I am using stock kernel (cant unlock booloader) and flashed 4.0.4 stock ROM.
The other problem is that i have tried like 4 or 5 different cusrom ROMs. All of them supporting locked bootloaders but they always get stuck at Sony logo at first boot or enter a bootloop. When they enter to the bootloop i get to cwm but i dont know what to do for fixing it. And when it gets stuck in the sony logo i cant even get to cwn and i am forced to connect again to flashtools and start all over again to have rooted ICS...
Any help would be very appreciated!!
PS: any other owner of lww notices a slight noise coming through speakers while playing quiet music through them?
Sorry for my english! I'm fron Chile

Before you flash the ROM you have to wipe data/factory, wipe cache partition and wipe dalvik-cache. Additionally i do "Format /system," . If you not wipe you got the bootloop. Apart from that you need to use correct ROM and recommended kernel.
That wifi disconnecting issue i also face, but i can't identify what's the correct reason.
Oh. I forgot to tell that even formatting and cleaning dalvik, cache, system, etc. I get bootloop or stuck at sony logo. I double checked to install Real ICS for locked bootloaders but always stuck or bootloop.

Nokia reboot problem when trying to update

Hello!
I have a strange problem with my phone it wont update to latset firmware without get in some kind of boot loop.
The phone was runing the lastest firmware 1232.5962.1314.0017 before the problems started, it all started when some systems apps like camera, settnings, messeging. etc, stop working. All that showed up when entering the apps was a black screen say something like "reconnecting" and then it jumped back to home screen.
So I restarted the phone but then went in som kind of reboot loop where it wouldent go past the nokia logo. I tried everything soft reset, hard reset. The last thing I tried was to reflash the phone, I tried diffrent ROMs and it finaly worked with the ROM 059Q5C6 RM-821 GLOBAL BLACK SWAP.
The phone is runing now and almost all functions work exept camera and automatic brightness (all that I discoverd so far).
Its currently running the 1231.5951.1249.1004 firmware.
But like I said now when I try the update the phone it goes to the same boot loop state.
What should i try next?
Is the thread in the right place?

Same thing happens to my phone!! Did not think that it could be the latest firmware (1308 for me) could have caused it since I don't think there are a lot of us affected by it and my phone has been running fine for months after the update! I've restored 5 times, by the time I thought to flash it, it wouldn't charge anymore.... I'd sent mine for repair now... Have you fixed yours?

[Q] Stuck on HTC bootup screen, even though phone is actually booted up to homescreen

Hi all, hoping to get some help. I rooted my phone the other week and was using viperrom. I had no problems whatsoever, no glitches that I could remember. That is, until I decided to trade my m8 with a friends Note 3. I factory reset it and give it to her, I left the viperrom on because she didn't mind but then the glitches started to happen. The onscreen bottom 3 buttons disappeared for her (home, back,etc.), So I reset it again but the problem persists. I searched for an at&t stock rom and sideloaded that after master resetting, wiping the dalvik cache and all that... now a different problem popped up. It hangs at the HTC logo for what seems like forever, but then I noticed the volume up and down make a noise as if the phone is loaded up. I pressed the power button a few times and eventually the screen turned on and I could see the home screen. This happens every time I restart the phone and I have tried reinstalling the stock rom a few times. I am now in the process of trying a different stock rom.. the first was odexed and this new one is deodexed, I dont know if that makes a difference in my situation but does anyone know what could be causing this? Any help would be appreciated.
Nvm, after a few more master resets it seems to have sorted itself out... not sure what it was but its gone now.
If its the latest version of Viper, based on 2.22 software, you need to update the firmware package, otherwise the long boot times will continue.

S6 Edge boot loop/now logo showing before shutting back off.

I rooted my S6 Edge a couple of days ago with no problems. I later added xposed and a couple of modules, no problem (apart from swipeback needing removed after it disabled my camera/gallery). Last night I shut my phone down and put it on the charge for the night. Today after turning it on it was stuck in a boot loop. I have been searching for fixes but there seem to be many different scenarios. I have tried to boot to recovery multiple times to do a wipe partition cache as that seems to the general fix. Problem is I am only able to get into TWRP. So I tried to do a default wipe with TWRP (Says wipes Data, Cache, and Delvik (not including internal storage) ). My phone now only boots to logo before shutting back off. I assume anyway because it isn't boot looping anymore and holding the power button gets the same result, logo then black screen again.
I am able to get into TWRP menu though I should add just about any option I choose, after it executes/completes the phone freezes and needs to be forced off/restarted. It has done this since TWRP was installed.
I am also able to get to ODIN mode.
If I remember correctly it is the G925F Global model. Running 6.0.1 stock, rooted using SpaceX kernal.
This is the process I used to root: edit: Seems I cannot link until I have at least 10 posts. How to Root Galaxy S6/S6 Edge on Android 6.0.1 Marshmallow!
BY MAX LEE google that and top result should be the site I used.
Any help would be greatly appreciated. If you would need anymore info I will gladly do my best to give it. I would like to fix this without losing all my data, apps pics music etc. But if all else fails I am prepared for that.

What could be wrong with this phone?(Freezing, restarting, doesn't detect carrier)

Ok hello i'm pretty new to this, but I have looked around quite a bit and nothing seems to help. So my friend gave me this Galaxy S6 edge(more specifically the SM-G925I - TCE Mexico (Telcel)). The issue with this phone is that it freezes then restarts randomly and it also doesn't recognize the carrier. It recognizes that theres a sim but the carrier is not recognized and I don't have access to mobile data. The bigger issue at the moment is the crashes though. I already tried resetting to factory defaults, booting in safe mode, wiping the cache and wiping all the data/ factory reset from the recovery menu. I thought it was the OS or something so I installed twrp wiped EVERYTHING(pretty sure I did since when I rebooted twrp told me if I was sure since I had no os installed) and installed the official 7.0 firmware update from sammobile. It was previously 6.0.1 and I thought having a different version might fix the issue. Yet the issue remains, within a few minutes of me using it it freezes, turns off, and reboots. At this stage I might you might think its a hardware issue but when i'm in recovery or download mode it doesn't turn off. Also I decided to leave it charging when I left for work and when I came back it hadn't turned off at all. I checked the uptime and it was at 7 hours and yet within a few minutes of me checking the settings it froze and turned off. I'm not really sure what to do anymore i'll probably take it to a service center to see whats up but I wanted your opinions first. Thanks.
