Android software issue - the phone constantly reboots itself, lockscreen crashes. - LG Optimus 4X HD

Hi!
I have a really strange problem with my P880.
Yesterday I changed a few things in gps.conf file in system/etc and then rebooted the phone.
I went down to the kitchen, got back to my desk with hot tea and to my surprise - my phone went crazy!
It turns on, there's LG boot animaton, then for a little while lock screen appears, which disappears and there's only black screen with status bar. After a few seconds everything freezes and the phone reboots itself.
About a week ago I modified some files to add QSlide to my 4X HD and I guess those files might have brought these troubles.
What can I do? Should I flash V20B software via LG Mobile Support Tool? Will it clear all my data (music, pictures etc.) ? Can I save them somehow?
I'd be very grateful for any help. It's already over one day without my phone and it's driving me insane
PS. Sorry for my English, I'm not native

OK, problem solved.
I've "updated" (V20B -> V20B) the software according to instructions from here - http://forum.xda-developers.com/showthread.php?t=2069723 and the phone works fine now. Nothing is lost :victory:

[Q] Foce close error all installed apps not showing 2nd time...

Hi,
I have a rooted GT-i9000m (bell Galaxy S Vibrant). I used the one click lag fix to root my phone and it works fine.
A few days ago out of no where all the apps started auto closing as soon as i opened them and then both the menu and back touch buttons lit up and the screen went black. I held the power down till it rebooted only to get and error with com.android.calendar even tho I never use the app. When it finish's booting none of my installed apps are showing.
The first time it happened with com.android.app and I did a full wipe and factory reset and just reinstalled everything.
Ideally I don't want to system reset to factory settings again and lose all my files and notes that i copied back on to the phone 2days ago...
Please note I have tried clearing the data for the calendar app in settings -> apps and i cleared the calendar back up. My problem is that none of my installed apps are showing...
(Update) I also cant reinstall or update apps due to a Installation error - Insufficient storage. But there's room on both SD cards. I also set 850mb for apps when i did the one click lag fix and i don't have 850mb of apps installed.
(Update 2) I did a factory reset again this time i didn't format the internal and external SD cards. (It works like new again) Thus I got to keep all my personal files and ring tones ect. The only thing that was deleted that I didn't back up is my Notes. This leads me to my new question whats best for backing up apps on a rooted SGS (bell Vibrant)?
If anyone has answers they would be much appreciated.
i had the same problem
install rom manager from the market place
there is a option in there "Fix Permissions" just run that and it will fix it up for you
only takes 1-2min to run
Tried what you said but i cant install anything... I get Installation Error - Insufficient storage available.
I now understand the cause of the problem. I change my battery once and some times twice a day. At first I would wait for the long shut down (untill the screen goes totaly black) and then take off the back and swap out the battery. At least 3 times the phone would boot up and ask me for the network unlock code (I bought the unlock code directly from bell for 75$). I found this rather annoying so i tried just taking the battery out wile it was on (idle) and it appeared to work flawlessly at least 20-30 times before the phone would start to do an endless force close loop cycle. This kept forcing me to do a factory reset on the phone. I can only assume the one click lag fix and my disregard for the need of the shutdown before removing the battery must be all the cause of my problems.
I will try and see if my phone is more stable with out the one click lag fix.
nope that is not the cause of the problem
but it sounds like you are another victim of the lag fixes that is killing your internal SD card.
not the fault of the lag fix, it just make the problem apear sooner than later
I have been having a similar issue and I'm using Voodoo lagfix. I think it's because I took the battery out before it had completely shut down.

Well the phone bit the dust today. I opened up google maps to look up an address and it crashed with the usual error. So i rebooted the phone and now it stays stuck at the boot logo. (the glowing S with both touch keys staying lit) So i did the recovery thing again but this time I had to do the Vol-up + home + power in order to get the phone working some what. IDK but it wont let me log into my google account to sync my contacts. My APN settings are correct and working and I even tried off my Wifi at home. I'll just hope its a google problem and not my phone acting up. Thanks for the pointer to the bad internal SD. That may be the problem kinda hard to prove it to Samy thoe...
I get force close errors after about 4-7 days of use. Now its gotten worse. A few days ago I was looking up an address and my phone crashed and rebooted it self. It then hug at the S boot logo for 20mins. I got to my friends apartment building to find my phone still stuck at this boot logo. I couldn't remember his apartment number or buzzer code... Normally i just check my contacts list and buzz the code. I was standing out side in the Canadian fall cold wind trying to get this phone to work... OMG i almost just smashed it on the spot. Anyways I remembered about something i had read on this forum about the recovery mode ( i had used it to root ) so i tried that out got the little menu and tried every option before having to do the dreaded factory reset. Well nothing work with the exception of the factory reset it got my phone working in about 5mins... LOL
Anyways I thought I might try upgrading the firmware when I got home. What a mistake... I cant control my phones MP3 player via my bluetooth car stereo any longer. Tried everything even a factory reset and formatting the internal and external SD's. I tried running it with out rooting it again and with out the lag fix in hopes that I wouldn't get a force close error. Wouldn't you know it about 5 hours after the factory reset un-rooted just after i finish coping over all my music. I get a force close error! So I tried again and this time the phone ran for about 30hours before it started giving me force close errors about the email now...
Sigh I've tried just about everything in my power to make this phone work. So I assumed it must be the phone... I called Samsung up to get a RMA going... Wouldn't you know it they tell me that I have to call my carrier to get it RMA/repaired. I try to explain that I bought the phone with out a contract and bought the unlock code from Bell so I could use it on Fido. They tell me to call Fido... ROFL Fido wouldn't even give me their APN settings when i got this phone so knew they would be of no help. They don't even have one android phone in their line up i tell the sammy rep. So they tell me I should go back to the Bell store I bought it from to get it repaired/RMA'ed.
I doubt Bell will be of much help but here's hoping.
Do you think my phone is broken, bad flash, buggy memory, ect and needs to be RMA'ed?
Update...
I got my phone back from repairs 2 weeks ago. They flat out replaced the phone for a new one. This was a huge headache for me because the new one wasn't unlocked. Took Bell 2 hours to get the new one unlocked wile my wife waited out side double parked downtown! (I thought it would be a quick pick up and I would be out) The blue-tooth works flawlessly again!!
Much to my dismay the replacement phone has started acting up much like my first one did. It gets several force close errors a day and has gotten to the point where it no longer can send or receive text messages (using Handcent). The stock Music Player app also force closes at random with more frequently. It looks like I got another Lemon. This time around I did NOT root, lag-fix, or flash firmware. I will be sending it for repairs as soon as I can afford to buy another phone to use wile this one is off at repairs. My back up phone is a 3~ year old Iphone3g that my son has made his... (cracked screen, vol rockers dont work, power button is jammed in, the LCD screen it self is bleeding on the top edge)
The Vibrant never let me down other than as a phone. As a divx player or using all-share it rocks! I use these features A LOT to play my 720p divx movies on any TV or the projector in the bedroom .
with that being said I might keep the phone just as a portable movie player to bring from place to place and put my sim in something more stable.

StkAppService - com.android.stk restart loop?

Hello people, first post
I have this little problem that's been bothering me with my new O2X.
When restarting my phone, the SIM Toolkit service, StkAppService - com.android.stk, pops up in service manager, and seem to be running fine. After a while though, the service seem to get stuck on "restarting".
Haven't quite been able to lock down when/why. Seems to be connected to extended periods in sleep, or playing games, but this could be just random.
When shutting down the service manually, everything seems to be just fine, and it won't come back until I for some reason restart the phone again, then it it'll be back to working fine, and after a while stuck on "restarting" again.
Is this something I should care about at all? Just seems to me that having something stuck in a restart loop (could just take a really long time, not 100% sure it's actually looping yet) would drain my battery.
So, to the point. Could this be a fault of the phone itself (making it a warranty case), a bug with Android 2.2 (wait for 2.3) or an issue with my service proivider (in witch case I'll contact them)?.
Been unable to find the answer on my own, and this is my first Android-phone, so I consult you, the wizards.
Update:
Checked with a friend of mine who bought the O2X at the same time as me, and he also has StkAppService stuck on 'restarting'.
And the phone glitched out and refused to fall asleep by itself today. Restart fixed it though, haven't happened again.
Another Problem with STK
My problem with STK is another one:
I have two SIM-Cards installed in a dual-SIM-Card adapter. So with stock ROM switching between both cards via STK works fine.
Now I tried several CM7-based ROMs, but with all ROMs I receive the following error massage when switching to the other SIM (translated from German to English):
We are sorry! The process com.android.phone has been unexpectedly terminated. Pleas try again later.
After that, I can enter the PIN-code of my SIM and it is activated. I´m not able to switch back, when I tap on the app-icon it switches back to home-screen.
Any solution for that? (sorry for my bad English...)
Hi,
two years alter, I am facing the same issue, and XDA developers apparently are not working on including proper STKs with custon 4+ Android Roms.
It's a pity

Sliding won't work anymore

Hey guys,
I could need a bit of help! It's now the third time I'm having this problem, don't ask me why. I've got the feeling that I read the whole forum here, but didn't find anything similiar.
The 1st time I didn't change anything (ok, rooted it, but nothing else)
The 2nd time I overclocked it slightly (~850-900 MHz)
Now I'm using MIUI.
But back to the problem:
I'm unable to use the keyboard, every time I'm sliding open the keyboard (even when it's turned off), it "crashes". The screen stops working or it freezes, the only way to turn it off is taking out the battery.
However, the bigger problem comes now: I'm barely able to restart it. It tries booting, but is restarting all the time or the screen is just turning on (in some angles you see that it is turned on but it's black). After many retries, it starts working, sometimes the bootloop is running 15min or i have to manually restart it 10 times or more. The strange thing is that the keyboard works fine, nevertheless I have to choose between using it opened (taking it with me becomes difficult ) or closed...
...the main problem now is flashing a new Rom, I'm currently trying it through the android sdk and adb, but using the power-button + x is easier
I don't think that I can solve the problem, I sent the device two times back (warranty till may 2012), but maybe someone here knows a bit more. My guess is that one of the sensors is broken, or some parts of the display that should manage the sliding process...
Anyway, thanks for your attention!

the computer isn't finding it anymore...I'll back up the data and try use my warranty... I hope that they don't complain about MIUI...
But I'm still not getting the point, why my mobile had these issues three times, although they "repaired" it twice...and nobody else is having the same problem

Slow wakeup

Hi
I bought my lg 4x 2 weeks ago. Played around with rooting and deodexing (later I found the deodexing script on xda-devs. Thx great script!).
I had bootloops and no chance to flash the kdz because my pc doesn't recognize my phone. So I thought I can't use adb anymore.
Thousand of tries later I could upgrade via kdz flashing tool(luck).
Since reflashing my stock fw(10f) my phone is very slow after it was a long-time in standby. When I push the power button it comes up after 1-2seconds. Isn't much, but it's all the time even on calls.
I rooted first manually, then via script. Both nothing changes on wakeup time.
Deodexed(always losing lg keyboard...but I love it ), removed all bloatware nothing... v6 supercharger, forced launcher to memory via build.prob...nothing...still the long time to wakeup.
When it is woken up its fast. Amazing fast (I came from HTC Sensation)
Everyone else got this? Or somebody who can help to solve this?
Can you post your tweaks and what they change? (Especially build.prob)
Regards
Edit: power management tells me Android_System uses 61% of my battery power??
PS: sorry for poor english!
Hy
I have the same problem, slow wake up, did almost the same as you and nothing.
I have found the hidden menu in LG just type 3845#*880# and you will get hidden menu and allot of testing stuff.
Try everything, then just sent it to repair shop, and they changed the motherboard, so thats that. :S

Xiaomi MI A2 turns off when unplugging

Hi.
Today appeared some problems with my A2. When I woke up and unlocked phone it turned off. Yesterday everything worked perfectly fine. I tried like 20 times, everytime the same scenario- turns on, but when I type PIN, home screen is loading, and phone goes down. It may look like bootloop, but its not typical, cuz it goes farther than just booting screen. So I tried to fix, wiped phone, set lang. to Polish, and it dumps again, but I've read somewhere, that it might be language issue, so I wiped it once more and set English. It seemed to be working, but then I unplugged it from my PC (charging only) and it turned off immediately. Worth mentioning is fact, that battery is 92%. What may cause this? Is this some soft problem? Or more like battery issue?
Update: Phone works unplugged, but only on lock screen. Turns down when I unlock.

Hello, I have the same problem. I now have to carry an external battery with me, because plugging it in is the only thing that wakes up my phone. If I don't have a charger, then I have to hold power for 30; seconds to force reset. It's really annoying, causing me to miss calls and alarms. Anyone know of any fixes? Thanks
Hey,
I am facing the exact same problem. Though I had an additional problem. My phone didn't charge when I plugged it in until I restarted it. Factory resedidn't help either.
In both your cases the problem is your wifi even if you dont understand it ...
if you can unlock your phone quickly and toggle off wifi the phone wont reboot or loop
your persist partition is damaged from changing between pie and android 10 ..
look around for a flashable zip to repair your persist ( it does it exist )
or take the long root and use miflash to flash persist by modifying certain files in stock fastboot rom folder
but next time explain your problem better
--- what did you do -- change version ( update or downgrade ) -- did you root -- do you have twrp -- what version of android-- did you return to stock from custom or vice versa --- etc etc etc
