[Completed] [Q] Constant rebooting: i9100 Samsung Galaxy S2 :( - XDA Assist

Hi there-
My Galaxy S2 just last night started with some new weird behaviour. I had tried to use it for navigation earlier in the evening and left WiFi and GPS on accidentally... an hour or so later the phone was running hot and started rebooting (has never been super-stable, so I wasn't too concerned) - charging overnight and now the phone insists on rebooting after about 1-2 minutes.
Have rebooted into SAFE MODE, and things are relatively ok, until I open the SETTINGS> APPLICATION MANAGER... which triggers a crash/reboot almost immediately.
I've not installed any new apps for some time (nor bothered with any regular virus scanning) - and am not sure what's up with my phone.
I'd really like to avoid having to re-flash/factory reset... as getting one's phone back to "normal" can take months!
Any helpful input would be most appreciated.
Thanks in advance!!! =)

Maybe found the culprit? How to remove it? :/
Just in case anyone actually cares, I may have found some useful info...
Facebook Messenger has been very resource hungry and unstable... In my culling of apps I'm noticing it is the most resistant to being uninstalled. No matter how I find the app (in Rom Toolbox, App manager etc) - it won't let me kill it fully.
Attempting an uninstall of Messenger triggers an immediate crash/reboot.
How can I completely obliterate it?

I managed to "freeze" messenger with a lot of luck... though I can't remove it. Phone is kind-of ok... unless I open the Application Manager.
Seems Messenger doesn't want me even looking at it! (Instant reboot)
Any ideas how to remove this awful program?

[Q] Phone very unstable following "stable" CyanogenMod install

Hi, I recently purchased an HTC Desire with Telus in Ontario, Canada. Following a few days of regular service I got bored and decided to root the phone and install a custom mod. I am in no way blaming CyanogenMod for what has become of the phone, but it is nothing short of a frustrating nightmare these days.
The phone behaves extremely unstable, starting with random reboots, or inability to turn the screen back on following standby (having to pop the battery prior to powering the phone back on), down to constantly losing signal, inability to connect to WiFi, inability to send SMS messages. In fact, right this minute I am in dire need of sending an SMS and I am completely unable to get the phone to get a signal or send the message (the message either fails without telling me why, or gives me error 332). Aside from these problems, applications crash constantly, often simply unable to start-up.
I following the instructions in this wiki to the brim:
wiki.cyanogenmod.com/index.php?title=Full_Update_Guide_-_HTC_Desire
verifying versions (straight from the phone):
Baseband: 32.44.00.32U_5.09.05.30_2
Android: 2.2
Kernel: 2.6.34.5-cyanogenmod
Mod: CyanogenMod-6.0.1-Desire
Build: FRF91
I am at a complete loss here, and very frustrated. Any help or suggestions are HIGHLY appreciated...
I'll be the guy to make the 'obvious reply' since this forum seems to avoid making that sort of post =)
I'm a winmo user but from what I read, cyanogenmod android 2.2 with some modifications? Were you just bored of 2.1 and wanted to get to 2.2? Because there's an official update on the HTC site for that.
Otherwise, there is probably no setting or combination of settings that will act as a magic bullet and make the phone stable. If it's possible to overclock the phone you could try that, but even if that's an option it might make things worse. It sounds like strange advice since overclocking can also cause sleep of death and freezes, but I found my phone actually got more stable after. If you reach a point where you decide to get rid of cyanogen and flash a new rom, and there's some way to try OC first, you could give it a whirl.

Bluetooth (BlueZ) issues on Samsung Tab7.7 CarbonRom (latest by Daniel_hk)
Hi!
Having flashed this http://forum.xda-developers.com/showthread.php?t=2723126 pretty one, I've experiencing unstable bluetooth connection with almost everything. Philips bluetooth music station connects after 10 seconds only for half a minute then drops (i can see a slight screen flash-redraw on the phablet), car multimedia does not discover the phablet as a 'phone' device (only audio), which means no convenient hands-free for me. And I'm not alone to these problems: http://forum.xda-developers.com/showpost.php?p=55861531&postcount=103, 'alnon' describes same issue.
Can someone check out this ROM and/or confirm this bug? Also, if anyone knows of a solution/fix, please advise!
A Big Thank-You to Daniel
I've used some of Daniel's roms before, but I have to say that the Carbon rom is by far the best -- fast, with low battery usage, and a chance to use KitKat.
Thanks.
Samsung Tab 6800 CarbonRom

I just installed the unofficial CarbonRom(4.4.4) release on my Samsung Galaxy Tab P6800. I upgraded from official rooted ICS using TWRP. The tab boots up fine but hangs within a minute of operation. Please help and let me know if you guys have any ideas on what is causing this.
Regards
Here I installed last build (december one) and bluetooth cant receive files from another android, neither can turned off. I have a p6800.
Bluetooth bug... cant turn off
I really like this carbon Rom. It runs like a Mercedes SL. But i have one big problem,. Once i turn on Bluetooth, i am not able to dissable it. Every time i try to switch it of, it turns on itself short time after again. I think it is the so called "cant't turn oft issue". But i cant find a solution to fix this. Actually Bluetooth is always in in my Device. But i dont need it.
Any help would be great

Bluetooth problem
Hi there,
I was reading for years until I yesterday decidet to flash (from stock) to this rom.
All went fine (besides a corrupt backup, sh. happens)
All seems to work besides: bluetooth.
I thougt there should be no Bluetooth issue with this rom?
I can turn BT on or off, but the Tab doesn't find any bluetooth device.
I canNOT turn on its visibility for other devices. Its not found by eg. my pc.
Anyone who had the same problem?
With stockrom it worked all fine, no hardware change.
THANK YOU - to anybody who finds some minutes to care about a newbie

This Build work well except Bt
I installed the 12 december version with opengapps nano GAPPS package. But I get a horrible wakelock on google play services, no matter what I try. I can't seem to track it down or solve it.. (tracked it down with Wakelock Detector, GSAM Battery Monitor). It's preventing deep sleep. Any tips?
Tab 7.7 CarbonRom KitKat starts automatically when charging
Hi,
I've installed [ROM][4.4.4r2]p6800/p6810/i815(12Dec2014)CarbonROM Kitkat Unofficial on my tab 7.7. with TWRP recovery project 3.0.2-0. Although everything seems to be working fine, except known issues, I have one issue. When I turn off my tablet and start charging, my tablet automatically starts/reboots after a minute or so. Is there a way from preventing this automatically reboot when charging, while I my tab is shut down? I want to charge my tab turned off because it will charge much faster. I've been looking around for same issues of different devices and possible solutions but nothing seems to work for me:
- Disabeling Stay a Wake while charging.
- Turn off while charging cable is already connected.
- Switch to original cables, chargers or not using data cable
- Can't edit LPM, PLayLPM, IPod, etc., because I can't find such battery animation file
#!/system/bin/sh
sleep 40 (Maybe I can change the amount of time to boot while charging, e.g. to 100.000)
/system/bin/reboot
- Delete Cache and Data-storage.
- Maximize CPU Frequency to max. 1400 Mhz.
Can somebody please help me and find me a solution!?

The automatic reboot when charging was a bug in the old Kitkat Rom's that Daniel fixed with Android Lollipop rom's, its a feature of those builds.

Original Shield Tablet Freezes When Connected to WiFi

Hi there!
I've contacted nvidia regarding this issue (reps seems oblivious) and posted it on their official forums to no avail, so I'll try and give it a shot here.
Basically whenever my tablet connects to WiFi after being disconnected for some time (a few hours to a few days), the tablet freezes when it downloads notifications. The freezes can be minimal (like a 5 second freeze) or be quiet substantial (it can lock up for as long as 10 mins). Once all notifications are downloaded and displayed, the tablet then performs like a charm. I even got my tablet replaced from nvidia and it has the same problem as the one I sent in. Uninstalling Facebook and Facebook Messenger improves performance drastically, but when my tablet checks for notifications it freezes still freezes for a few seconds (with Facebook installed, it could lock up for 10 mins and crash the launcher multiple times). Running on max performance did nothing. I'm really curious if this is a hardware or software issue since some people doesn't seem to have this problem.
I'm running on nvidia's stock firmware (4.2) unrooted.
So here is my question. Have any of you guys experienced this problem? Were you able to solve it? How did you solve it (did a custom rom solve this)?
The main reason why I haven't installed a custom rom yet is because I use the stylus frequently and I use the touch-block feature in nvidia's stock roms and couldn't find ports of it.
Here is a video of the issue. (youtube.com/watch?v=cJrUPV7mY6s) Now there are a lot of widgets on the video, but I assure you removing all of them does nothing. I tried.
Facebook Messenger. That says it all. What other apps have you running in the background?
This definitely sounds like a software issue to me.
Maybe you're being hijacked. Who knows.
I've had this same issues since I got the tablet (K1). System reset, no non-Google apps. Happens regardless of FW; I'm on the latest update. Don't be quick to blame the OP.
Basically, every time the tablet gets a new network connection, the system hangs and becomes unresponsive for 10 seconds to 2 minutes at a time. It's obvious that it's updating all the apps' network requests. However, the thread priority should make the system hang. I've only seen this issue on the K1; never on any other Android device. Either they're using a custom network stack, or they've messed with networking priorities.
I'm on the latest update

Of Facebook Messenger? Or OS? Or all apps?
Either way, it makes no matter no such issues on Lollipop. I am just saying.

Android 7.0 evening memory exhaustion

Hi all,
I've got a Moto G5 Plus running Android 7.0 running stock firmware. Every day between 22:00-23:00 the phone is unusably slow, looking at the developer options and Tinycore resource information the memory is exhausted but CPU is pretty much idle. Rebooting the phone doesn't resolve the issue, only waiting until after 23:00.
Investigating the issue I've used SD Maid to examine what is running. Killing running tasks one by one doesn't help, nor does killing background services. I can't pin the issue to a rogue app or background service, the slowdown occurs independently of intensive background tasks (Google Photos backup, device backup, built in Play Store security scan). It seems like the issue is a low level OS one. I'm posting here rather than the device specific forum to check if this is a known issue with early Android Nougat builds. I'm at the mercy of Lenovo and still waiting for updates to bug fix point releases.
This has happened since day one of having the phone and I can't see any of the typical causes applying. I don't have any silly apps installed - Cheetah Mobile task killers, anti virus or any apps from nasty sources. I don't use task killers regularly, I only have SD Maid for monthly cleanup and this issue happens every night. Writing this now the phone is doing fine, 20 minutes before 22:00. Around 2.3 GB of memory used according to Tinycore but as we cross 22:00 it will shoot up. At first I thought this was uptime related but it's 22:00 which is the trigger.
Is there anything I'm missing? I've tried searching but the majority of posts relate to a rogue app, the time related trigger seems to be special. Apologies if I'm being silly. As an aside I've switched from iPhone to Android, I had a Nexus One back in the day (Android 2.2) and had years of free iPhones from work. Android has been busy in the intervening years and it's a great platform!
Thanks in advance.
Switch the net off, to check it's not internet related, like updates

Thanks for the reply. I've tried switching off mobile data and wifi, and turning on aeroplane mode, they don't make any difference. Forgot about this in my post, sorry.
I have disabled Google Play Store auto app updates. Even if this was the cause I'd expect to see something in my process list showing background activity / services gobbling memory.
Maybe it's something that has been fixed in Android 7.0.1.
Posting just in case anybody else has the same issue...
I'd activated the hidden Night Mode in Android 7.0 using Night Mode Enabler / System UI Tuner. Turning off Night Mode fixes this. Presumably this is why Night Mode didn't ship in 7.0!

S7 with custom rom(s) and Xposed - Internet connected apps breaking

Hi all, long lurking rom-installer who can self-fix most problems here. Got a problem I can't fix that's bothering me. Recently upgraded to an S7 so naturally rooted it on day one and been trying to get it my-kind-of-working fully ever since. I do like to bugger about with things in a vain attempt to shield some private data from some orgs and realise I'm in a particularly specific hole that I'll probably have to climb out of on my own, but if you don't ask...
Internet using apps pretend to work, sometimes for days, then just refuse to open. Screenshot example of the second and persistent error (after simply "Lightning has stopped" the first time) is attached.
Model: G930F
Current ROM: ambasadii 7.0 TW Nougat (here)
Xposed: 88.2
Root: Magisk
Significant mods:
1) use xPrivacy
2) disabled significant number of remaining packages using Package Disabler Pro (list attached)
3) run Orbot
4) run AFWall
5) modify app permissions in Settings/Apps to restrict where I think I safely can
6) run BackgroundRestrictor
The behaviour still emerges even if I don't apply 4), 5) or 6), it has started prior to me finishing my tweaking.
I know xPrivacy is not supported for Nougat but it seems to work ok for the most part with some retweaking of settings since moving from Marshmallow on my old phone. I understand it could be the cause of the problem but I'm wedded to (some of) my privacy enough to persevere before abandoning it. For the record I've checked the usage log for restrictions on any calls around e.g. internet that might be interfering but I've been unusually generous with permissions trying to fix this and there's no restrictions on any apps with internet access around that, or much else really at this point. I've also had a look in general usage log rather than app specific, looking for system components that may be working alongside the app and failing with a restriction but can't see anything being denied. Any system apps haven't been touched by me, I fetched what I could from xprivacy crowdsourced restrictions on the base ROM apps and then only applied my template to apps I've downloaded myself.
Some other background on the problem: everything will be set up as I like it - ROM installed, debloated, all the rest of above modding applied. It will be working super-fine. Nice and fast, little bloat left, just enough Google to get Play Store, apps installed and working, all will be and appear fine. After an undetermined & fluctuating length of time all of the internet-facing apps will suddenly not open. This includes but isn't limited to the Browser (stock and Lightning, Brave, Pale Moon, etc.), Twitter, Signal and the Official TWRP App.
Interestingly, internet-connecting apps that will connect on demand but don't seem to make a call on every app open (mostly due to prior settings changes) do not fail. They will still open fine and work fine, connecting when asked and not crashing. For example, K9 Mail and Pocket.
Another weird data-point: Signal will fail but will often do so later than the other internet-connected apps - possibly it has a token with GCM or something that when it expires will try to renew on app open which is when it starts to fail like the others?
The apps will work again if uninstalled and reinstalled but once the behaviour starts again, and it will, it will repeat. Sometimes twice or more in a day. So reinstalling every time is not going to make for a usable phone. It's like they have an error renewing their wifi lease or something.
It can take up to three days to begin - this build it worked fine for days whilst I was away and slowly, progressively building the system back up with regular TWRP backups. I can restore a TWRP backup from about 6 hours before the problem started and it'll work fine again, but still wait a random amount of time before the problem begins again.
I did think it may be something to do with the router here and home WiFi as it behaved much better whilst away and didn't break until my return, though that is likely coincidence. I'm in pattern-observing mindframe so false positives are everywhere. I thought it was connecting to the PC via USB that was doing it at one point.
Last data point: it's happened with a different base rom too (Decent here), same thing, but came on sooner each time. I would change the base rom again to see if it's something there but I suspect that should be one of the last things I try given it's happened across two roms now.
Anyway, if anyone has any insight on Nougat TW ROMs on an S7 with this kind of set up and/or any clues or ideas as to why internet connects would suddenly be crashing all these apps... I'd be grateful. Otherwise I have many reinstalls and possibilities to eliminate. Which means waiting many sets of days before I can repeat, which makes progress frustratingly slow when you depend on the phone (Signal particularly) to connect with people.
AFWall stands out if you're having problem with net connections to apps etc
Yes good point, thank you. I think i've run the ROM with same problems without any rules applied but I've disabled it fully now just to be sure. Much obliged.
If it persists, the proper way of troubleshooting would be to clean install the ROM only, no tweaks, Xposed, firewalls or anything, just the ROM and your apps you're having problems with
If that all works together fine, then add ONE new thing to the mix, test for a few days, rinse and repeat until you add something that causes the problem again
With testing for a few days between each new addition you're be 100% sure what is causing it once it starts again
Thank you! Yes that's the plan but I thought I'd ask first as there's a lot of waiting down that route. I did do it to a point during last build but only waited overnight after each phase. I think I'll start that.now. I can always restore this backup if the solution presents in the meantime.
Yea that's what I was thinking, backup this ROM, clean install, work out the issue, restore this ROM and fix it
Good luck
Thank you I'll report back if/when I work it out, for any other possible future readers.
I changed the base ROM & installed Xposed in a different way and rooted in a different way and tweaked Permissions to be more permissive and and and... I've read rovo89's farewell so I won't say "It's xprivacy" but it's definitely how xposed & xprivacy interact, whether by flashable zip or systemless magisk. It'll work fine for a good while but then starts corrupting everything internet connecting. Removing it removes the problem & restores the app functionality.
Sadly it's the same even if you restrict nothing in xprivacy & just leave it installed & switched on. I've had to remove it. Considering trying to go back to MM as I know it worked on my previous phone.
