When I power off and power on, the phone reboot constantly

[victorfriasv]

After power off and power on the phone, it reboot every 10 seconds on. Not is neccesary introduce pin.

[theotherJohnC]

Is this after a clean install? What build of this rom are you using?

[bzh2610]

I have this issue too. Plug your phone into a charger/computer, reboot your phone. When the phone asks for the PIN, unplug your charger, type your code, plug your charger back and it should work.

I've experienced the same issue on Beta2 and Beta3, both on clean installs.

[victorfriasv]

Yes, I did a clean install. I have this issue in Beta2 and Beta3 The temporary solution is plug the phone when started.

[theotherJohnC]

I can't replicate this bug, both on clean installs, dirty installs with 4.4.3, etc.

[victorfriasv]

Anyway I just upload a video of this bug. http://youtu.be/D1O9zzzZW_Q Also happens in beta3 pre5

Known L bug http://m.pocketnow.com/2014/07/08/android-l-as-your-daily-driver

Closing as Android L bug.

Known L bug http://m.pocketnow.com/2014/07/08/android-l-as-your-daily-driver

I don't think this is what the L bug refers to. It seems to be talking about the PIN re-locking the screen instantly, not rebooting. The author then mentions manually rebooting to fix the PIN re-locking. Are we sure this is a known L bug?

I can confirm this bug. Clean install from latest stock, after flash it worked yesterday, I set up some apps, rebooted, all working. Now today suddenly bootlooping till lockscreen, I can even unlock it (swype), but it restarts 5 seconds later. Already check2fs'd /data, wiped /cache and dalvik and did even format /system and reinstalled from .zip, then it boots longer, rebuild app (that thing with app xx of yy(somewhat around 90) and bootloop again. Any files I could check what's the cause, like logfiles? I have no pin/sim card and no unlock code. For me it looks like a service/app starts in background and cause this. Charger connected don't change anything.

[The1andONLYdave]

After lot of searching and trying, it is the wifi connection, if I poweroff my router my nexus is working, or if I turn off wifi. I already disabled (with autostart app) every app under android.net.conn.connectivity_change. It's not a hardware problem, since with clean /data everything works. Will check next week if it happen with different wifi-networks.

[Sykopompos]

Clear your known WiFi connection and reenter your info. I swore I seen something mentioned about that causing issues with the auto backup WiFi or tibi backed up ones

[The1andONLYdave]

I cleared one wifi, reentered, and after exactly 5 seconds it reboots again. Or do you mean clearing (how?) the whole saved-wifi-database? I too tried blocking everything in afwall+, but no difference.

[Sykopompos]

I'm not sure what is going on with it then because this seems to be a very limited issue. Is it a 5ghz router? Have u gotten a logcat so we can try to track it down?

[Sykopompos]

Are you guys on 5ghz routers? If so check the second post on the Dev thread and trying changing the WiFi channel

[The1andONLYdave]

It's a 2,4 ghz wrt54gl mixed (B and G) wifi with wpa2(tkip) encryption. The other wifi is a bb10 hotspot. Logcat is on http://pastebin.com/n5hvnhY2

//edit: My bb10 device allows only 2,4ghz wifi access, so i think it makes only 2,4ghz Hotspots too.

[Sykopompos]

this is what is causing your crash right here "android.database.sqlite.SQLiteException: Can't downgrade database from version 589832 to 524296" it looks like an app causing it. I see dropbox and facebook going at the same time

[The1andONLYdave]

Got the same error in this logcat http://pastebin.com/34bxAq93 This one is after i boot with a sim-card(without pin) it crashes com.android.phone every 2-3 seconds, but no reboot.

Dropbox is not installed, do you mean the dropbox folder under /data/system/dropbox? looks like some sort of tombstone- and crashlogs in there. Should i upload them too? But i can't copy it, even with root and open only very few files in it (about 1000 files there).

After uninstalling Facebook, it still reboots 5 sec after connecting.

[The1andONLYdave]

Uninstalled every app(except titanium/totalcommander) and disabled google-sync and deactivated all apps, it still reboots ( http://pastebin.com/SieHx3k0 ). Any idea where i can find which sqlite database is the one mentioned in logfiles? Then i could try copying it from another install. //edit: deleted sqlite .db and .db-journal from com.android.providers.telephony and .userdictionary, 2 of 4 got rebuild at next boot, and it's finally working again with both wifi-networks. Will try to get all apps up again, sync set up, restore twrp and check if deleting this files only, fix it.

[The1andONLYdave]

It definetly were the incompatible sqlite databases, probably they came from a carbon restore of userdictionary and sms-mms, but after the restore the messages showed up nowhere so i thought it just failed. why android l uses a older (downgrade) version than 4.4.4 is another question. Maybe the other Person with crashes after boot/wifi have a similar database problem?

[mattjanicki]

So which SQLite databases did you end up deleting?

Edit: Nevermind, I see the update about /data/data/com.android.providers.telephony and .../com.android.providers.userdictionary. Deleted the files and haven't had a reboot yet, but I suppose we'll see.

[The1andONLYdave]

Folder /data/data/com.android.providers.telephony/databases/This 6: mmssms.db mmssms.db-journal telephony.db telephony.db-journal blacklist.db blacklist.db-journal (blacklist could be something similar, don't get rebuild, so can't check atm)And folder /data/data/com.android.providers.userdictionary/databases/ all two files (.db and .db-journal can't check exactly name too) Von: SurlyDuffGesendet: Samstag, 12.

Hi guys.

Lightflow notification control is the cause of this.

http://reactle.blogspot.co.uk/2014/07/l-preview-details.html?m=0

L Preview Details Version 3.20.107 of Light Flow adds in compatibility for the Android L preview.

At the moment there's a few issues, but versions prior to this cause a boot loop in android (ie shortly after the phone boot's it'll reboot with lightflow installed)

This seems to be an issue with L I've raised an issue on the android L issue tracker here: https://code.google.com/p/android-developer-preview/issues/detail?id=667

[The1andONLYdave]

I don't have/had Lightflow or similar installed under Android L, only the clear-notification apk from clockworkmod team.

[dnewsholme]

Does the clear all notifications display an icon in the top left always? Even when notification tray is closed?

If it doesn't it sounds like it could cause the issue.

[Sykopompos]

so it was the sqlite databases from a backup that was causing this?

[mattjanicki]

Seems so. Haven't had any other issues recently.

[Sykopompos]

Well now we know that we got a sqlite incompatibly between 4.4.4 and L now though

[The1andONLYdave]

Maybe you can put it at the xda-thread? That restoring SMS/MMS can cause bootloops at the moment.
