Temperamental...

My G1 has recently started playing up. The problems first started with cyanogen 4.1.9999 - it would loose signal, but a reboot sorted this out and it may only happen once every two or three days if that. It was an unstable ROM, no biggy.
But then one day, after rebooting, it got stuck at the android screen then just turned itself off. This repeated several times before it just wouldn't turn on. I left it for a while and tried again later, it turns on, boots but no signal. Rebooting did nothing.
I reflashed (without wiping) cyanogen 4.1.999. and everything seems okay. But then the phone started crashing and rebooting rather a lot, and rather unpredictably. So I wiped, flashed the ADP rom and then cyanogen 4.2.1 rom. This process was a massive brainache - plugging in the usb cable managed to crash the phone within 2-5 min guaranteed, it automatically rebooted.
So here I am. Cyanogen 4.2.1 - after a complete sdcard format, wipe, ext3 repair and flash. The problems still persist! But it's temperamental, a lot of the time I loose signal still, it often reboots itself and hates anything plugged in the usb when it's turned on - making charging the thing awkward.
I used the log collector app to get these logs

http://nopaste.info/2e98b9d044.html
At some point during those logs, the signal is lost. The log collector doesn't seem to retrieve a very long backlist, these were taken minutes apart but don't overlap, so I haven't caught a crash. I'm not sure if there are better ways to view logs/debug?
But it's all very temperamental. Occasionally it boots up and life is fine. But more often than not it will loose signal and reboot itself somewhere along the line.
Has anyone come across anything like this before? When it looses reception if I manually try an connect to a network it will say
"This SIM does not allow a connection to that network"

I've read that could perhaps be a problem with the sim... but the sim wouldn't cause reboots would it?
Any advise would be great. I bought the G1 off ebay just under a year ago, so no warranty.

MAJOR problem - phone restarting every 10 seconds!

Hi guys,
this is my first time using these forums and I wouldn't have done that if the problem was easily solvable. However, this is a major problem for me and I couldn't find a thread nor a solution to it, so I'll post it here.
I have the i9305 4G version of the S3. I have had it for about a month now, and it worked fine, up until now. The phone suddenly starts to restart itself (not reboot!) for about 10 seconds, then goes back to the dashboard.
The problem seems to be the WiFi. Right after I get the "Connected to ... network" message on the bottom of the screen, the phone vibrates immensely once, then everything freezes for a few seconds, then another 2-3 vibrations, before the Samsung logo comes up with the LED light on. After a few seconds again I'm back in the dashboard until I get the "Connected to ..." message, and so on the process repeats itself.
Turning off WiFi seems to solve the issue, but once I turn it on again the problem reoccurs.
Something else I've noticed is that if I have WiFi turned off and cellular data network (for instance 4G) turned on, the "4G", "H+" etc. logo does not appear, even though I'm connected to cellular data! Don't know if it can be related to my main problem.
I have tried everything I'm aware of. Unplugging the battery, factory reset and back up, hard reset, wipe cache pertition. After the factory reset I can use WiFi again, but only for a few hours until the problem reoccured. I THINK once my battery is fully charged the problem occurs.
Note: I haven't even touched stock ROM, kernel etc. Nothing is flashed. Phone is in the same condition as when it came out of the box. Android version: JB 4.1.1
I would be forever grateful if you could help me out here, I can't have a phone restarting itself and vibrating like crazy every 10-15 seconds.
(Sorry in advance if this was the wrong place for this thread.)

UPDATE:
Seems like my issue isn't just related to Wifi. Cellular data network was actually related to my issue, as I first feared. If Wifi is turned off and cellular data turned on, the same thing happens. Seems like the issue occurs every time I try to use the internet either way.
Anyhow, if I let the phone reboot itself without turning on or off anything at all, it will reboot about 5 times until either Wifi or cellular doesn't work anymore even though the status bar tells me that it is turned on!
This seems to be a serious connectivity issue and for the first time I'm suspecting interference with the phone's wireless network hardware. If none of you are able to provider an answer, I guess I have no choice but to hand it in to get it repaired or replaced.

Still noone who has a solution to my problem?

My solution to your problem would be to just bring it to whoever you bought it from and demand a replacement. That isn't normal behaviour.

you can boot into recovery and do a factory reset and cache wipe

if wiping does not solve your problem, just return your phone.
I don't know if this is related, but, I had this issue once (the cause is not wifi though), and samsung fixed (or replaced) my phone.

I'd wipe the phone and return it. This is not normal behaviour and should fall under warranty... Wiping might fix but this may happen again if there is an inherent problem with your handset....

[Q] Stuck in bootloop even after battery change

Hi,
I am new to this forum and do not know much of the technical terms. So here is my problem as best as I could say...
I have a unlocked Samsung S4 purchased last Sept (Philippines/SE Asia version, I think). The phone worked fine until the latest upgrade to Kitkat 3 weeks ago.
A week after the upgrade, the phone started rebooting itself. After checking this forum, it looked like a battery problem. On checking, it did have a swollen battery. At the same time, the S4 stopped working as a phone - meaning I could browse, use apps, but could not make calls.
First changed the battery with an original from Samsung, hoping everything would sort out. Unfortunately, it did not. The phone still kept restarting and the network signal showed as not available. So I went to my provider and got a new SIM card and changed it.
Unfortunately, that has also not solved my problem.
Now, my phone keeps rebooting itself. If I connect it to the charger, then the phone starts successfully. At times, it behaves well, but suddenly/randomly, if I touch an app (any app, no pattern) it will reboot again. Once it starts rebooting, it keeps doing that in the screen which has the samsung music comes - it would turn off again and keep restarting until that screen reaches again. Only if I connect to the charger would it start. Again, there is signal at times and there is no signal most of the times. My area has good network signal, so that should not be the problem.
I tried clearing the cache and clear all data/apps, but still no luck. Also, my battery still has / holds charge - so that is not the problem.
Could somebody please help me!!! Please let me know if you need any other details regarding this.
TIA.
Baseband version: I9505XXUFNBE

1. Sig & log in Sammobile.com
2. Download ur firmware: HERE
3. Unzip it
4. Phone in DOWNLOAD MODE
5. Flash the firmware through ODIN like the pic attached

It has nothing to do with your battery...but yes a swollen battery can be dangerous. Follow the steps told by @Joku1981 and don't upgrade to kitkat. Wait for a stable release from samsung.

Hi,
I have already upgraded to kitkat, so cannot downgrade now.. . I had the request to upgrade to kitkat by the phone (Samsung).
As mentioned by Joku1981, I downloaded the Philippines firmware and did as mentioned. However, the phone was still randomly shutting down on opening some apps (esp Gallery, Playstore, Chrome) and failed to reboot.
I also tried to download the pit file and flash it again as mentioned in http://forum.xda-developers.com/showthread.php?t=2265477. Still no lock.
I tried with UK's version of firmware, still same problem.
The phone can be restarted only if connected to the usb cable.
The "No Signal" issue seems to have been solved, but the rebooting randomly seems to be a real pain now.
After my latest flash, while i was in the third screen setting up the phone for language/accessibility --> "wi-fi setup" --> "Accept Samsung t&c's", the phone shut down again...
Is there any counter to identify the number of times the phone is flashed? Would it cause any problem?
Thanks

Also No Service now!
Also noticed that after the last 2 restarts, the network signal shows full strength. However the default lock screen shows "No Service" (see picture). When I try to call when the phoneis in this status, the phone gets stuck in the dial screen and has to be rebooted...

Though you flashed, do a factory reset one more time to be on the safe side - make sure the phone is 100% charged, and given your case do NOT touch the phone until the reset has completed.
One more thing to try - from experience some batteries are bigger than others and you said your previous one became swollen. This may cause the power pins to become too compressed causing the new battery to lose contact. This manifests on the phone as rebooting at the slightest of movement/flexing, try this:
1. Remove the battery
2. GENTLY pull out slightly the power pins on the phone - don't pull too hard.
3. Put the battery back, put a piece of cardboard or something at the bottom of the battery to make sure there's good contact
Let us know of the results

Nothing seemed to work but only got worse. The phone could not stay on even for a few hours. Finally gave it to the Samsung Service centre yesterday. They sad it might take upto 3 weeks if there was a motherboard change needed.
Fingers crossed...:crying:

intermittent signal drop & unresponsiveness problem

I bought a Xiaomi Redmi Note 3G last September and it has been performing fine until very recently.
The phone works fine approximately 75% of the time, but intermittentlythe following problems occur simultaneously:
- Signal drops completely and 'NO SIM' is displayed
- The battery level drops around 1% every 20-30 seconds
- The volume and power buttons are unresponsive
- Wi-Fi disconnects
Sometimes the phone recovers from this and starts operating as normal,and sometimes the phone restarts and goes into a boot loop, eventually turningback on. Whilst the above problems occur,most other phone functionalities still work i.e. can still open upapplications, and swipe around the home screen.
Can anyone help?
Thank-you
EDIT: I should add that since this problem started I have tried a different rom and the problem has remained.

Hi,
have u wiped ur system (cache dalvik) before installing another ROM?
Try to pick a ROM that is confirmed to be stable to avoid bugs.

Stock device locking up randomly and won't respond

HI Everyone
I've been having problems with the device within a few hours of getting it. I should have returned it to the store within the first 30 days but due to having all my apps installed and suspecting it was a software issue that would be resolved in a software update, I persisted with it.
The symptoms are that the device randomly locks up and is completely unresponsive and can't be unlocked. The only thing to do is press all four buttons and reboot it. When it locks up, the AOD is visible but the time has stopped. When I call the S7 from another handset, it does nothing and on the other handset I get a network message saying that I'm not available. Sometimes it seems to snap out of after 10 minutes, and other times I can leave it for hours and it doesn't change until I force it to reboot.
I've tried a factory reset and not installing any apps at all, everything stock except adding my Google account and connecting it to Wifi. No customisation, I've not changed the wallpaper, ringtones, nothing. But the issue persists.
Its been back to the store for a signal test due the issue being logged incorrectly as a signal issue. It passed the signal test and has had the latest firmware installed but the problem happened again today. I left the device for over an hour whilst I driving and then forced it to restart.
Has anyone else experienced a similar issue?
