Jolla device in a boot loop
 

Alright, here goes.

My device have entered some weird bootloop, and I haven't even started fiddling with it.

Had it in the charger over night, in the morning it just reboot's all the time.

It boots up, shows the Jolla logo; then the led turns red and it reboots. Again and again.

Anyone got some pointers, so I can get the device running again :-)

Re: Jolla device in a boot loop
 

1) What charger did you use?

2) Did you enable developer mode at any point and if so, what did you (exactly) do with it?

3) What SW version are you on?

Re: Jolla device in a boot loop
 

Also, 4) Are you in any way trying to use the device without a battery in it

Re: Jolla device in a boot loop
 

1) The device ran out of battery the night before, and I charged it with a charger from an iPhone which was available were I was at the time. Put it in the charger when at home, using the charger from my Nokia N900, which I have been using all the time since I got the device.

2) Yes, I enabled it, connected to the device through ssh; thats all. Didn't do anything else than that.

3) The most recent - 10.0.1.12

4) No, the only thing I can think of; is that I pulled the battery out at some point without shutting the device down.

Re: Jolla device in a boot loop
 

USB or Charger connected at that point?

Re: Jolla device in a boot loop
 

Pulled the battery out, took out the sim; put the battery in again, and then connected the charger.

Re: Jolla device in a boot loop
 

Is there something I can do to get the device running again; or provide additional information ?

Re: Jolla device in a boot loop
 

If you show up in #jollamobile on irc.freenode.net, you might be able to find some people to help you further diagnose.

Do you have a Linux PC?

Re: Jolla device in a boot loop
 

I'll show up there.

I have a Mac, will that do ?

Do you have a hunch of what has happend ?

Re: Jolla device in a boot loop
 

I had this issue few times with my N9.

What's happening is your battery is too low to boot up the kernel up to charge the phones battery, so it will keep in the loop but never start up.

the way I fixed it for my N9 is using the flasher, it somehow allowed to get more power the from USB and actually charged up the device.

Re: Jolla device in a boot loop
 

@mariusmssj your suggestions doesnt work with Jolla

Re: Jolla device in a boot loop
 

Ahhh I see, Well hope it can be fixed.

Re: Jolla device in a boot loop
 

If it's true that the device cannot start up a charge from flat, it's quite a serious bug and needs to be addressed. Given its current power consumption, the battery can easily go flat rather quickly; I observed an 11%-point drop (from 20% to 9%) in a 45 minute Facebook chat. Most phones are able to take power from USB alone and charge a flat battery.

Re: Jolla device in a boot loop
 

It's wasn't due to battery being depleted; it was in the charger the whole night.

The problem was a corrupted filesystem. It has been solved and the Jolla lives again !

Re: Jolla device in a boot loop
 

how did you solve it?

Re: Jolla device in a boot loop
 

Jolla Care, i think :)

Re: Jolla device in a boot loop
 

in Denmark ? well ..... if so, where :)

Re: Jolla device in a boot loop
 

With the help of Stskeeps, it was due to a corrupted filesystem.

Re: Jolla device in a boot loop
 

Big thanks to stskeeps for this rescue mission.

So you can make file system corrupt with over charing. Something isn't right in this story...

Re: Jolla device in a boot loop
 

Probably because the battery was removed while the device was switched on.
I still wonder how such a bad corruption can occur with btrfs. Or was it some other non-btrfs partition essential for booting?

Re: Jolla device in a boot loop
 

Okay... if removing the battery while the device is on can corrupt the filesystem, what happens if a butterfinger like me drops the device so that the battery flies off? Or If a butterfinger like me drops the device whilst changing Other Halves? Then the battery is pretty sure to fly off.

Re: Jolla device in a boot loop
 

Hmm, have to keep that in mind for the future. I had to remove battery on the fly today as device got stuck to scanning of WLANs and even power-button didn't work anymore. Luckily nothing like this happened.

Taking battery away when phone is completely stuck is something which I learned with Nokia's phones over the years. Pretty much automatic action for me.

Re: Jolla device in a boot loop
 

I, OTOH, quickly learned NOT to do that with the only Nokia phone I've ever owned - the N900. I go to great lengths to avoid pulling the battery out while the phone is on. The most common is to kill the stuck process via SSH.

Re: Jolla device in a boot loop
 

OK. So far I haven't had to kill stuck processes - although my Jolla has shown the "Unnamed app is not responding" message a few times, so it has some kind of a watchdog. The last time was when I had some 40 unread Fb messages and there had been network problems in the meantime. That time the Messages app was having problems.

Re: Jolla device in a boot loop
 

Well, most of my past phones were Symbians (with exception of N9).

Re: Jolla device in a boot loop
 

How did you exactly fix this? Mine is stuck in a reboot loop and it's definitely not battery.

Re: Jolla device in a boot loop
 

If you managed to update to 1.0.2.5 there is recovery mode:
Recovery mode

If a factory reset cannot be performed or if the device has booting issues,

Unplug USB cable and turn off device
Press volume down and power on the device
Plug in USB cable and using USB networking telnet to 192.168.2.15 or 10.42.66.66 and follow the instructions

Re: Jolla device in a boot loop
 

Thanks for fast response! Unfortunately, it didn't work:

Re: Jolla device in a boot loop
 

Ah. Is the device still in reboot loop after that?

Re: Jolla device in a boot loop
 

wow, terrible situation.
I hope it recovers!

On a note, what an excellent example of a situation that might be easier cured BOOTING CUSTOM KERNEL FROM AN UNLOCKED BOOTLOADER JOLLA!

Is it in some ways possible to break that recovery script, to get to a shell prompt I wonder ...

Re: Jolla device in a boot loop
 

@kehno, that seems to be quite unlucky, might even need to be returned to care for reflash.

Re: Jolla device in a boot loop
 

Yes :(

I guess that's what I'll have to do. Hopefully it's just fluke in my device, like bad flash chip and nothing widespread.

Re: Jolla device in a boot loop
 

I have the same problem, how can i fix it? nothing happens with vol- + power on ..

Re: Jolla device in a boot loop
 

Unplug USB cable and turn off device
Press volume down and power on the device
Plug in USB cable and using USB networking telnet to 192.168.2.15 or 10.42.66.66 and follow the instructions

Re: Jolla device in a boot loop
 

the phone with the battery in, keeps rebooting, no way to turn it off, if i remove the battery, when i put it in it keeps rebooting

Re: Jolla device in a boot loop
 

try
take out battery
push and hold volume down
insert battery, while keep pressing volume down
insert usb
hopefully you will now be in recovery

Re: Jolla device in a boot loop
 

the usb should be connected to pc or the electrical plug?
PS: thanks for the quick response, i hope it works =)

Re: Jolla device in a boot loop
 

To PC
you will need Linux to get USB network

Re: Jolla device in a boot loop
 

ok, i'm downloading ubuntu, will it work with a virtual machine?
and after started ubutu what do i have to do to use USB networking?
Sorry i'm a bit inexperienced with this..

Re: Jolla device in a boot loop
 

sudo ifconfig usb0 192.168.2.16 netmask 255.255.255.0 up
telnet 192.168.2.15

instructions should then come on screen

VM should work, I often use that.
