Can't fix bootloop - Android Q&A, Help & Troubleshooting

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.

[Q] HyDrOG3N-ICS 13.05 - Weird bootloop

A couple of nights ago, I accidentally let my phone die. It must have been doing something important, because I kept getting force closes on all stock apps and also apps that required root including superuser. I rebooted to see if that fixed the problem but it didn't boot up after, I figured it wouldn't be a problem and deleted my cache and dalvik and rebooted. The phone booted to the lockscreen saying "Upgrading android, Optimizing x of x applications" but I noticed that when it got to the 33rd app, it would suddenly go very fast and the phone would crash to the boot animation (not the boot logo) on "starting applications". It wouldn't boot back up until I did a hard reboot. After a while, I realized it wasn't going to fix itself and just wiped and re flashed everything. I did restore some user apps in tb and everything was fine. On the next day, i made sure that the battery didn't die but i woke up to the same force closes and bootloop when i rebooted. Tried to delete cache and dalvik again to see if i could reproduce the problem but now it wont boot past the animation at all.
Im using siyah 3.2.7.2 and my second rom (which boots fine) is Pure ics
EDIT: On 3.3.1 now, doesn't make a difference

[Q] Stuck in bootloop

I am rooted but running stock ICS via the last OTA update. For the last few days, my RAZR has rebooted randomly when I would tap on an app notification from my status bar. It did not make a difference what the app was that I tapped the notification for. Sometimes it would reboot, sometimes not. This morning I woke up around 3 AM and tapped a notification. Of course my phone rebooted and now is stuck in the reboot animation. I tried booting into recovery, wiping cache, and rebooting. It did not work. After a couple of hours I gave up and decided to reset the phone to factory settings. Ah success or so I thought. I started to set the phone back up again but the phone rebooted and is once again stuck in bootloop. I am stuck now on what to do. Any suggestions?
I'd be using RSD software to flash a different stock Rom. Here is how and all you need:

Just confirming that I've got an Australian RAZR, bought from Optus and I've flashed the European UK version without any problem. After RSD does the job, you may have to boot into Recovery and wipe the cache and data, just in case you get stuck in a bootloop.

my phone is stuck in bootloop, but sometimes im able to turn it on

i had my phone for about 2 years, it has been rooted ever since i got it and its running custom rom and custom recovery CM 13 on android 5.0.1 and TWRP . about a week ago i was charging my phone, when i unlocked it, i'm unable to go to the home screen because whenever i do that, google app crashed and the phone redirected me to the recently used app tabs, then i tried to reboot my phone and it went to safe mode but then i restarted it and its stuck on bootloop. so i let it be for a while, then it show the "android is starting" tab and "optimizing app number "xxx" out of "xxx" and after it finished, again it is stuck in CM's logo. however, then i put my phone to fastboot an restarted it and i dont know, it turned on again after 2 boot loops. a week after, my phone ran out of battery so i tried to turn it on but it wont , after reading threads on the internet, it suggested me to erase the cache and the dalvik cache. so i did and it turned on. today, i ran out of battery again and i erased both cache and dalvik cache, but it wont turn on.. i have no idea what's going on with my phone, and im a newbie so please go easy on me thank you.

Moto C plus freezes and reboots.

I'm using Moto C plus since past 2.5 years. Last week it suddently restarted. I thought it may be an issue of main memory full. So, let it to restart. But it went on a bootloop. I had more than 2GB free in internal storage. Then I wiped cache and tried booting. It booted successfully and then after 5-10 seconds it froze again and restarted and the bootloop continues. I tried wiping all data but no luck. I tried system root integrity check which failed. I flashed stock ROM again and started phone but the same issue continued. It boots successfully, I get home screen and then after 5-10 seconds reboots.
I thought of flashing custom ROM then. I flashed TWRP. While I was flashing zips using TWRP, TWRP itself restarted randomly. I somehow flashed DotOS and Ressurection Remix with GAPPS but same issue existed.
Now I'm back on stock ROM. Sometimes it boots successfully and then after using for 5-10 minutes it randomly reboots and get stuck in a bootloop freezing on Moto logo or Lenovo logo and then restarting.
What could be the issue here? Is there a hardware problem?
