Is it a hardware problem? - Xperia SP Q&A, Help & Troubleshooting

Hi. I have very strange problem wit my phone. It gets random reboots all the time.
I use fxp latest nightlys, but i've tried cm and even got back to stock, and it still happens. I thought it was cause of oc or smth with system files. And the thing is it does not have a regular patern.
I wipe cache/dalvik or flash rom, phone boots and it is ok , next when I use it it reboots very often or even worse sometimes i can't get it working again coz it reboots, and when android is opening it reboots right away and then i have to flash rom again or clear dalvik.
Anyone can help ? Do I have to use warranty?

I recommend a complete fall-back to stock; which means flash everything (baseband, FOTAkernel, kernel etc) you can in Flashtool. If problem still persists, it really might be related to hardware, though this is only my guess.

Use a different rom or start from scratch on the one you're trying to use(not your nandroid)

Yes - well I have observed these symptoms before.
The kernel is falling over loading the audio drivers.
It's very strange but if you slow the boot process down you can work around the problem and then get the phone to boot. Once it has booted once the problem doesn't tend to reoccur very often. I have only noticed this on a handful of phones although I can reproduce it from time to time.
When "stuck" (it is actually boot-looping as you observe) reboot to recovery using adb or finger-gymnastics and wipe dalvik-cache (or cache for that matter)... but you need only wipe one of them. Reboot the phone from recovery, should boot as normal but may take a loooooong time the first time...
Please report back, I'd be interested in your findings.

i will try it later tonight. the part that's bothering me it's that i loaded several kernels on my current nandroid and every single one is working fine! when i flash a new rom though i get this issues...
hmmmmm nop... not working. i flashed, and rebooted. pulled battery and wiped cashe same thing. then nandroid restore, flashed again, restarted, pulled battery and flashed dalvik. same thing...
i think i sorted out the issue... dunno why it happened but i flashed the stock rom part by part via fastboot and it seems that everything is fine now...
I had the same issue. It happened on every single ROM + Radio combination you can think of, including stock everything. Finally gave up and sent my N1 to get repaired. Received it a week ago and it's working again. They also re-locked my bootloader... And now here I am contemplating unlocking it again... but I don't want to go through that experience again.
I'd send it in rooted or not, if you still have the problem going back to stock.

[Q] Stuck on LG screen [Solved]

Hello, this is my second post here though I visit this forum quite frequently.
I have a p990, and I have encountered a very strange problem with my phone:
Until yesterday, everything was normal, and every couple of weeks or so I installed a new/updated rom via CWM without any problem (usually).
Yesterday I installed the CM7 Kang from Ricardo, and this also worked well. However, when I tried to install my previous rom again (Gueste 3.1, after 3 wipes of course. The reason I didn't go back to a nandroid backup was because of problem in making the last backup) it got stuck on the 2ng LG screen. the buttons are lighted when I touch the screen, but even waiting 30 minutes doesn't change anything.
Since then, I tried to install many different roms (the latest CM7 nightly and some others), and all gave me the same problem. The only things that I've been able to do in order to boot successfully was to revert to an old backup that I had, or to install MIUI, which did work for some reason.
When I tried to install the same version of CM9 again, I always got a boot loop.
Any idea as to what could cause such a strange behavior and how can it be fixed?
Sorry for the long post, I just wanted to give as many details as possible, and I'll be happy to give more details if I can if there are things that I forgot.
Thanks,
Beorn

Try this: go to recovery > mounts and storage and wipe system, data and cache, and flash your rom.
If wiping system doesn't work neither, catch a logcat when the phone bootloops

This fixed the same issue for me.
Wiped everything and flashed CM9. Works great (but battery drain is incredible!!!)
Solved!

Thanks, I did this, and now I was able to boot again with Gueste 3.1 (I'd rather wait for a bit more stable and mature version of CM9).
Actually, I did this thing twice, and it still didn't help, and in the third time I tried to make a logcat (I'm rather new to this logcat thing), and while trying to boot and make a logcat at the same time it suddenly started workind
I just hope that it will stay good now, and that I won't have this problem again in future flashes...
Thanks!

[Q] Internal memory dying?

hey guys, recently I have been experiencing a lot of crashes and other weird things.
sometimes the android gapps process or acore process would stop forcing me to reboot my phone.
the strange thing is, sometimes it will behave as if it was a first boot, so it would ask me to enter my details etc.
but after a battery pull and rebooting, it would boot normally.
however, it has also come to my knowledge that when i boot into CWM recovery, half the time it would say
"can't mount cache, etc etc etc" when it boots into it, and i cannot successfully flash on or wipe anything.
so it takes another few reboots to get it to finally work.
im on 2.02 blackrose running CWM 5.0.2.0
any ideas guys? cheers! :3

My Nexus 7 just did that after I screwed around with everything in fastboot.
Try this:
\Change to 4EXT
Backup
Full wipe
Restore
My Incredible S doesn't see much screwing around any more and its still fine. I only had that problem after changing bootloaders to blackrose, then I wiped and the problem is gone

Need Help Urgently, Hard nor Soft reset works

hey there, i'm doing this for a friend
he was updating to JB i believe OTA and it crashed.
It was stuck on the boot screen, but i got pass that, and the phone was back to the way she was using it.
However it kept rebooting randomly
So I tried doing a soft reset, deleting everything, plus i tried doing an updated on samsing kies, cos it shows that the jb update is available
but once the phone reboots, it goes back to the it was when i got it pass the boot screen, like its going back in time.
When it turns on, customer battery power saver is on and it starts downloading 4 apps...
whenever you restart the phone, it goes in a loop of doing the same thing.
I've even tried a hard reset, same thing, boots and starts the loop all over again
this is very confusing
I even tried using Odin to flash the original rom, odin shows success and the phone reboots....back to the loop state...
what can be done?
I will really appreciate the help
thank you
strange situation ... I am guessing that you are on ICS ROM ..
try downloading one of the safe kernel's first and then clear the cache or re-install the stock ROM from this safe kernel ..

Problem restarting Galaxy Note

Hi guys
I have a problem with my Note. I have installed several roms over the last year without any problems. Recently though I had a problem. I had been using about a week or two the ROM SuperNexus but a few days ago the powerbutton started not to work. It would at some moments work and some other moments it wouldn't. Very frustrating. I reinstalled the ROM, still didn't help. Then I installed a different ROM. It worked but not for long. Now it also started to reboot itself every 5 minutes or so. No idea why. I decided then to flash a new kernel. Abyss didn't work like I wanted so I installed Speedmod kernel and then installed the stock JB rom. Now that worked all fine and well. No problems at all, but the weird thing is when it gets to about 20-30% on battery, it reboots and then gets stuck at the bootscreen.
Why would this be? I'm afraid there is something really wrong with the phone. Does anyone have an idea what this could be or how I may be able to fix it?
Thanks in advance
Daniel
Edit: Also should not when it gets stuck at boot, wiping data/reset factory helps. Also when it's stuck at the bootscreen, it does get warm I find.
I just did a test with the App eMMC BrickBug Test and it said that Yes. Insane chip.

1. Boot your phone in recovery and flash the latest kernel from here
http://forum.xda-developers.com/showthread.php?t=1789397
2. Restart and allow some time to settle.
3. reboot and do wipe data /factory reset, wipe cache, wipe dalvik
4. Use pc Odin to flash stock ROM from sammobile.com
5. Check if it works and update...
