Hi All
I searched all the threads related to boot loop but did not solve my problem. I was in stock lollipop and my phone was working without any issues. One fine day I felt that the phone is hot and tried rebooting. The phone was struck in the initial graphic screen. Tried restarting again but the same result. After multiple failed attempts, tried doing a factory reset from the recovery with no luck. Thought that something got corrupted, installed twrp and did a fresh install of the factory image. That also did not help. Then installed Chroma ROM and then back to Kitkat factory image and all the attempts failed. Then tried installing Chroma ROM again and after a long wait, it booted up. I inserted the sim card and the network was not detected and hence had to reboot again. The reboot resulted in the bootloop again. Then installed CM 12.1(without sim) and it booted after considerable amount of wait time. Then inserted the sim card and it was not detected and had to reboot again. Now struck again in the boot animation. Is this a hardware issue? Also does the SIM card insertion requires a restart in Nexus 4.
Tried clearing cache/ dalvik cache and did factory reset, file system check but nothing worked..
Can some one help me on this..

Have you tried out the Nexus Root Toolkit? I know most are against toolkits but it really can't hurt in your situation! Try following the guide while having the SIM installed. And yes, SIM card insertion requires a reboot.
Good luck!

I flashed a rom the other day and a couple minutes after flashing the rom kept rebooting not goin past the Mytouch splash screen. If the sdcard is in it'll reboot about 3 or 4 times and finally boot up or just removing the card it'll boot up normally. I unrooted to see if that was the problem. Same result I've tried different cards reformatting and everything and the cards work on other devices. So I'm assuming its the phone. Is there a way to fix or am I just stuck with a phone that can never be rooted again ?
Also when I go into recovery I get the" E: can't open /cache/recovery/command"
I had Cyanogenmod 6.1.1alpha8.1 on my spica. Recently it got a little bit laggy so i decided to flash it with odin to restore the original firmware and install everything else from the beginning. I tried to flash it with I5700XXJH6. The flashing went fine, but when spica started booting, only the first, static bootlogo showed up and there was even no progress bar. After 20 minutes nothing had happened so i tried to flash it with 1.5, then install Lk10 to get into recovery mode, so i could get access to the phone's shell. Unfortunately, after flashing everything was the same - static bootlogo and no progress bar. Installing LK10 went fine, but the phone still wouldn't boot into recovery mode. I tried many different ROMs and one of them worked - the system booted properly, everything seemed to work at first glance, but when i inserted the SIM card and input the PIN code, the phone got stuck on "Unlocking SIM card". I tried rebooting many times but it didn't work.
Once again i tried to flash it with odin and everything was the same as before. I tried a few times, but now there's no download mode and when i connect the phone to the charger, nothing shows up on the screen.
Is there anything else i can try to do?
i had and solved the same issue yesterday.
I think part of the issue is maybe with a previous FileSystem conversion and another part with data/cache from previous Roms.
Try to make an install as clean as possible.
- I5700XXJH6 with Odin
- LK2.08 with odin
now you have an acessable recovery.
- boot the phone and put the CyanogenMod 6.1.1 alpha8.1 (found on 'forum dot samdroid dot net') on the root of the sdcard.
- shutdown the phone.
Important: disconnect the phone before booting in recovery, else it will boot normaly.
- boot in recovery (Volume down, accept call, on/off button)
- apply the downloaded zip.
reboot normaly, if it loads normaly, yay!
If it doesnt load (wait 5 mins to be sure) pull out battery.
reboot in recovery, and wipe data/cache (factory reset)
reboot normaly, if it loads normaly, yay!
If it doesnt load (wait 5 mins to be sure) pull out battery.
reboot in recovery, and make sure data,cache and system are rfs.
to change it to rfs 'advanced>filesystem conversion'
reboot normaly, if it loads normaly, yay!
if not send me a PM.
I already tried installing I5700XXJH6 and LK2.08 but neither the system nor the recovery mode would load - only the first, static bootlogo showed up. I can't try again because the download mode doesn't work any more and when i connect the charger, the screen remains black.
As I wrote in the first post, i managed to get it working once, but it had problems with the SIM card, so i tried different ROMs, which seems to have broken my spica entirely.
Is there anything i can do to restore the download mode?
im assuming you tried starting downloadmode without it being connected to a pc.
I dont know how to restore downloadmode, perhaps the guys at the samdroid forum can help you out.
Hello guys, i'm having a problem ;f
I was on cm12 nightly when i decided to reboot my device after few days of running, strange thing happend and i ended up in bootloop.
I've downloaded 4.4.2/4.4.4/5.0.1 stock images and tried to flash it guided by the instructions in this thread, however i still get a bootloop, even after clean installation, even after wiping cache and doing a factory reset.. I've managed to boot up my device twice since yesterday, after getting stock image to work i pushed cm12 and gapps on my phone and flashed them.
At the first try, i got bootloop again, so i decided to go through the whole process again, many attempts later i've managed to boot up my device again, and again i decided to flash cm12 and gapps, this time my device booted up properly so i wanted to gain root access, in order to do so I flashed UPDATE-SuperSU.zip file and as a result end up in bootloop again.. I have no idea wtf is wrong with my nexus. I am still trying to flash factory image, and i always end up with bootloop.. I'm out of ideas here, HALP! ;(
@update:
I have uninstalled all drivers, and mount my device to another usb port, then with NRT i installed google's drivers, by using nrt i have flashed 5.0.1 factory image, rebooted into recovery and wiped/factory reset, after that i rebooted my device and still no luck - hanging on floating dots for 15 minutes..
Before all of this I tried formatting my cache to FAT and to sdf4 and it didn't help, I literally tried every single instruction i could've found ;/
What's wired is that when i encountered bootloop yesterday and wiped/factory reset i booted fine, after restart it went into bootloop again, so i thought i would wipe/factory reset again i'll be good to go, but.. it didn't help this time oO
things i've already performed:
1. fastboot oem lock/unlock
2. wipe data/cache/factory reset
3. flash factory images of 4.4.2/4.4.4/5.0.2 through NRT/manually
4. converting partition to fat and next to sdf4
5. reinstalling drivers
6. different ports and usb cords
6. i even tried switching motherboard from my old n4 and i still stuck at bootloop *LOL!?*
7. after 6 i thought it may be related to usb port so i switched usb port from my old n4 and it did help but.. until next reboot ;/
from time to time, after flashing it boots up just to make my hopes and then it gets the bootloop after restart ;/
@update2:
It seems it's hardware related issue. I have tearn down my nexus device and left only motherboard with fron/back cameras and audio jack, daughterboard, i even disattached the speaker along with antena. At this point i flashed factory 5.0.1 and it works, i'm in the moment when i plug peace after peace and turn on the device to check if it still works. I'll update when i find out what was the cause of the problem.
@update3
Stupid as it sounds the issue was caused by the vibrator module, while it was disattached, the device was booting up without any problem.
Hi!
I've got an N910C with Lollipop ( I did a factory reset after upgrading and cleared cache) . It randomly decides to reboot, and will keep doing so. After a reboot, I can use it for about a minute till it reboots again. Booting into safe mode fixes it temporarily and it stays fine after safe mode, a regular reboot doesn't help.
I'd prefer not to factory reset, and would like to find the cause (app/sd card? Sandisk 8GB btw)
Cheers, thanks!
My N910A does the same thing except the times it reboots can vary from a minute to an hour later, but it reboots a lot.
Doesn't happen in safe mode only regular boot mode. That tells me it's either an app or SD card.
I swapped SD cards and same issue. I wish there was a log I could look at to see what app is running at the time of reboot, but haven't found any logs that have that info.
I'm stuck and running out of ideas.
Try factory reset again man and remove Sd and try to boot it
You can identify where the problem come from
My Galaxy S4 VE (GT-I9515) crashed. (the screen went black) It was not rooted and ran the latest Andoid 5.0.1 ROM.
When I turned it on, it went into a bootloop, randomly crashed during booting, or turned on normally. I removed sd and sim card and tried a different battery. Furthermore I tried to boot into recovery mode and wiped the system data and the cache. It did not help.
Sometimes it was not possible to get into recovery mode because the phone's screen went black and it rebooted.
Then I tried flashing multiple stock ROM files using Odin, but it did not solve the problem.
After that i tried rooting the device and installed a custom recovery (TWRP), but i still got random crashes during booting and sometimes it got stuck showing the samsung boot animation. The only things that work reliably are the Download Mode and the charging animation.
Now, what can I do to fix my phone?
I read a bit about flashing a .pit file but I don't think that will help?
Is this a hardware or a software issue?
How can I find out, what caused the problem?
