bootloop - Nexus 4 Q&A, Help & Troubleshooting

This has happened to me a couple of times on different roms and android versions. Phone is slow or freezing up so I restart it and it goes into a boot loop. I try to wipe cache and fix permissions but it keeps bootlooping when I restart. Only way to fix it is to wipe data and reflash rom. Has this happened to anyone before? I just want to know what is causing it so I can prevent it. Thanks for your input.

Does the same thing happen on a stock ROM? If it does, may be it's a hardware issue with the internal storage?

Ha I've never been on stock long enough to really tell, couple of days max. Usually happens after couple months for me on a certain rom.

[Problem] My DHD randomly reboots

Hi guys,
i was thinking that after flashing a new ROM and wiping everything, this issue will be gone. But isn't.
I cleaned contacts on everything (SIM, SD card, battery,...) no change. (it is also rebooting when there is no SIM and SD card)
Can you help me with this?
Biggest issue is that it happends in the morning, when alarm should be ringing
Here is the vid of the issue

Did you wipe system, data and cache? Not restoring from titanium backup?
If not, do that. Most issues like this are just some remaining data or some restored data.
Else try a different kernel, most have a undervoltage that works with almost all phones but might not work with yours. Add more voltage or switch kernel =)
Hope you manage it
sir did you try to use a different sd card to install the rom? just wondering because if this is a board problem i think it should at least boot properly or not at all. im not really an expert but i think that there is a problem with the flash
My DHD started rebooting randomly this weekend It's happening every now and then, but one time it was constantly rebooting until I was able to do a complete restart.
I'm using ARHD 6.1.2 atm, and will try 6.1.4 to see if it helps...
Yes, before flashing i always wipe cache, dalvik cache, data.
I am not using any software for restoring my data.
I tried another RADIO, but no change

Do you use any sort of CPU overclocker?
I had exactly the same problem, my fix was uninstalling SetCPU and flashing the Set_to_default_1GHz.zip
After this solved the problem I tried OC Daemon, which brought back the problem. Some CPU`s just cont handle overclocking or undervolting

If nothing happens with custom roms, go back to stock rom. Install an RUU. Then see what happens...
No i was not overclocking my CPU. Today i flashed original RUU, and i am going to send my phone to HTC. Because plastic cover is doing some sound, music jack is broken and the phone is rebooting. I think that they will change my motherboard.

[Q] Stuck on Samsung boot logo when rebooting from different roms

Having an issue that I cant seem to figure out. I have been using various roms eg Omega V7,S4 Google Edition V16, Fox Hound 1.1 etc. They all install fine, factory reset before and after wiping the various cashes as required. I also format the SD storage to be sure, but once up and running, apps installed, every time I restart the phone or for some reason it freezes it just get stuck at the white Samsung S4 logo.
If i go back in to recovery (TWRP 2.6.0.0) factory reset does nothing to fix this. I have also noticed that sometimes the internal SD shows as 0 Mb, and I have to reformat this to re-install a ROM. (Getting corrupt some how?) Only re-installing the ROM from fresh seems to get my phone up and running again. Until something happens. Any ideas?
I follow all instructions as detailed, and never come across this issue with my S3.
Ok after trying a few things the only thing that seemed to fix the problem was reflashing stock firmware using oden.
I had to reformat the internal storage again as this was acting like it was encrypted, which it was not. Think this problem that caused my phone not to boot when when restarted.
No Idea why it did this but its fixed now.

[Q] CM & PA question

I got a question guys, i flashed the latest version PA for our device (PA4.5 beta 2) and notice i was having random reboots, i thought it was the rom, so i flashed CM latest nightly (2014815) & still was having reboots, so i figured it had to be an apk not playing nice & thought i was right when i noticed it was happening the most while using chrome, but it happened during the settings and some other apks, its not constant though, it very random, its like when you stay on an apk for a while, it just randomly reboots, anyone else been having this issue? or had this issue?, i both like two great theses for these roms & would feel like a fool if i cant use em lol, so any help would be appreciated, thanks
Are you wiping between flashes or dirty flashing?
If flashing clean, restore your apps (without data backups) one at a time. If you stop having the issue, then restore your app data one at a time.
If that doesn't fix it and you're flashing clean, going back to stock and doing a factory reset will almost certainly solve the issue.

I always clean flash, I decided to flash sacs until a next major builds releases, thanks though
What kernel are you using?

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?
Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.
Same here...experiencing the same prob...
Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.

The reboots happens after some days randomly....

Had the same problem on stock ROM, but the last update with january security patch fixed it.
Maybe a factory reset fixes the issue?

I did make a clean install through TRWP. WIPED cache and dalvik cache. deleted internal data and system data.
I had random soft reboots before I was on fulmics Rom as well. so I think it's not specific to this Rom....
how many times did your device rebooted?

On which base is Fulmics yet?
The reboots happened once a week, or sometimes even twice a day.
I had this happen on stock. After much reading of logcat output I was able to determine some kind of system table was getting exhausted. Proceeding on the theory that some app must be misbehaving to cause this, I disabled or uninstalled as many apps as I reasonably could, concentrating on what I could remember having installed or updated recently, and the reboots went away (I am paying close attention as I gradually re-enable or re-install stuff but haven't found a definitive culprit yet).

I had the same thoughts.....cause the issue is not taking place continously.... so I don't think it is ha hardware issue.... still couldn't find the app which may lead to a random soft reboot
