random reboots - Sony Xperia P, U, Sola, Go

since i've updated to the .67 fw there sometimes are random reboots, the phone freezing, the LED lights up and it just reboots.
i didn't wipe the stats while upgrading via flashtool.. could that be the cause?

[Q] Crazy phone behaviour after flashing..

Hi guys, I've installed many CFW without problem, until I installed the latest PACMan build. I didn't like it so I reflashed the Hasa v6, that i've been using for a while, and the phone just got kind of "crazy". I tried to wipe/format/wipe delvik, flash another rom via recovery, flash the stock FW with flashtool, still the problem continue.. I'll try t make a short list of the problems:
- Lockscreen usually hangs the phone, screen goes all black and playing with the power, after a while, it goes back sometimes
- Some force-closes (mainly the system process)
- Sometimes I can't boot to CWM, the "back" and "option" touch-buttons keep lit, and that's it, sometimes I can
- Also the battery status doesn't seem to be working properly, I charge it and it never pass the 30% mark, or get stuck on a number beforr it
How can I do a "brute-force" wipe, or something like that to restore my phone to it's normal state? These issues are driving me mad, and I can't see a solution..
Thank you very much!
The device is a Sk17i Mini Pro
Try flashing a kernel like LuPuS v3 or MESA Hybrid v3.7 via Fastboot and then flash the latest ROM that was working flawlessly.
Thanks, I tried with mesa and Lupus and after that, the same issues seem to occur..
Adding problems:
- I started having the "build prop" error, always when I flash CM-based roms, and I never had this issue before these problems (I do the workaround to install them by editing them with notepad++ and removing first lines..)
- The phone, once in a while, stay with the back and menu buttons lit for ages..
- The phone doens't turn off completely (menu and back and the screen stay lit, the screen is black, but it's ON), the only way to truly turn off is removing the battery..
- When I choose "power off" from the bootloader, the same issue occurs, the screen stay lit in black and phone doesn't turn off..
Please help.. I just don't know what is happening and it is so frustrating.

[Q] The phone reboots itself while charging and random somtimes

Hi there, I have a problem with my GS3, when it's charging I see that the LED light is going blue, and the phone is stuck like that for a few minutes, and then it reset itself. Plus, it does that sometimes during the day, randomly, exactly the same way, the LED turns blue, and it is stuck like this for minutes and then it restart and boot's back up, or when I long press the power button.
I am using Android Revolution 26.0 and I did a factory wipe when installed this Rom.
What can I do?

[Q] 5.0, Mostly Boot Loop with Battery Icon

Device: Galaxy Player 5.0 INTL (YP-G70)
ROM: Cyanogenmod 10.1 (7/23/2013)
Kernel: Sultan r5 INTL
Problem: The battery appears to be malfunctioning somehow. After using "Pimp My Rom" and enabling some tweaks, the device began to randomly turn off and loop on and off with a white battery outline onscreen. Now, the battery has sufficient charge. When it finally turns on, it's always over seventy percent. When it does turn on, if it is plugged in on the wall charger, it immediately turns off upon disconnecting this wall charger. Also, it displays "Android is upgrading, starting apps" at every boot. Managing to turn on the device after doing a reboot with the power button many times takes up to 15 minutes. It sucks. ):
Steps attempted:
Reflashing ROM and kernel using exact steps (wiping all data, /system, cache, etc.).
Flashing Cyanogenmod 10.2 (8/05/2013) with Sultan r6.
Deleting battery stats.
Cleaning charger and microUSB port.
Rechanging tweaks to the values I remember in Pimp My Rom. (IDK about all of them, if someone could post the defaults that would be great).
Draining battery (I did to 1%) and then recharging. Should I drain until it turns off?
[EDIT]: Tried flashing to Chip v1.5 with r14 kernel. No luck; it is just a different battery icon.
[EDIT]: Tried flashing to stock with Odin.
Are there any steps that I could possibly take to fix this? Perhaps flash to stock and see if the problem persists?
[WORKAROUND!] I've found a workaround, however annoying it may be. Plug in the YP-G70 and it should bootloop with the battery icon. However, as the icon disappears and the screen is black for about a second, just before it is about to reboot with the icon, pull the charger from the device. This has guaranteed my device to start every time; I can't ensure that it will work for you, but it is worth a try.
Please help!
You need to either do a factory reset from within the settings or wiping factory reset from within CWM. If that doesn't work you may need to flash back to stock.

I have done many factory resets from CWM. Would flashing back to stock do anything that flashing another rom wouldn't?
Also, after scouring xda for answers, I saw iurnait recommended draining the battery until the device turns off. I'm going to try that I suppose.
I'd flash back to stock if that doesn't work

Unfortunately, flashing to stock using Odin didn't remove the problem.
I used a guide from androidromupdate
To be honest, I've given up. I'll update the original post with what I've tried and the workaround that I've found for this dreadful issue. If anyone else has this issue, best of luck!
I've got the same "boot loop with battery logo" problem, but without the random shutdowns are "android is upgrading" message on boot.
Some additional details:
I can boot into download mode without any trouble.
It will occasionally complete a boot, but gets stuck in the loop as soon as something causes it to reboot or shutdown.
I can sometimes boot into recovery mode. It will successfully go into recovery mode about 2-3 times before it will go into a normal boot.
Flashing alternate kernels (even going all the way back to stock) just changes the battery logo, but does not stop the bootlooping problem
The stock kernel was far more reliable than the others, often booting all the way after only 3 or 4 tries.
Throughout the boot loop, the battery logo (except in the stock kernel) will show as empty, even after being charged overnight
Upon a successful boot (all the way to android home screen), the battery is shown as fully charged (if it's been charging) or a level that seems probable (e.g. it'll show as 70-80% if it's been in download mode (which keeps screen on at full brightness) for a while or left to bootloop for close to an hour.
If it's not plugged into a charger, it only loops once each time you turn it on (i.e. battery logo shows for a few seconds then the device shuts itself off).
An update to Joseph's posted workaround:
I've found the button lights a perfect indicator for the timing. Wait for them to go black and then come back on very dimly then unplug the cable before the screen shows anything or the key lights go full brightness (like they are when device is fully booted and awake).

Phone bootlooping a lot and starts mostly on connecting charger or USB

Hi,
I've YUREKA+ smartphone and since yesterday, I'm facing this weird issue.
On turning ON my phone, it shows the YU logo and then soon reboots again and again and again... Some time it reboots at the boot logo, some time it reaches till the lock screen and then reboots.
However, when I keep it on charging and turn it ON, it works without any issues.
Issues-
1. Facing boot loops.
2. TWRP boots without issues but while flashing ROM (except AOSParadox, no idea why) or kernel, it reboots.
3. While restoring through TWRP backup.
4. While wiping cache and dalvik.
5. Wiping Cache & dalvik cache became very fast, damn fast. It happens in just 5-10 seconds.
6. While installing apps and gaming.
Except point 5, none of these issues happen while charging. 6 point doesn't happen while charging but on keeping it connected to computer via USB, it happens after some time.
---
There are only two reasons which I guess might have caused any issue-
1. I had flashed an custom ROM, which was charging my phone pretty fast (though, battery drain was also high). And many people has increased charging speed to 1.5 Ampere (it's 900 mA by default and stock charger is 1.5 Ampere/h).
2. I had flashed an custom kernel, which was causing bootloop in my phone.
Please help. I don't wanna take it to service center as they take months to send back the phone.

Can't fix bootloop

My phone (Vestel Venus V3 5020) is bootlooping and I tried turning it back to factory settings and wiping my cache partition and restarting it after turning the phone off and waiting for like 10 minutes but my phone is still bootlooping. Before it started bootlooping I downloaded an update because my clock and the battery level stopped and the keyboard wouldn't open. Also, I rooted my phone but then I removed it before it started bootlooping , help.
