[Q] Clock Setting Back to Default 1/1/2009 After Restart

My Acer A500 always resets the date & time to 1/1/2009 when I restart it. But yesterday when I checked with my friends A500; that isn't the case. His tab had the correct date and time after restart.
Can anyone tell me if there is any internal battery needs changing?
"Restart (Offing the tab waiting 10sec and starting it up again)"
Running Stock Honeycomb 3.2.1

Is your tablet encrypted?

Nope. It is not encrypted.

I was looking at the internal breakdown, and I didn't see an internal battery, other than the main battery. Not like you would see on a PC for example.
Probably, because the newer hardware uses Flash memory, unlike PC's in the old days, which relied on EPROMS and a battery to keep things updated on the Prom memory.
So, unless anybody has some other input on this, that I don't know about, I'll pull a sherlock holmes, and use the deduction method.
This probably didn't occur after you first bought the tab, and the OS was fresh. Otherwise, you would have returned it.
And By the way, what is your current Android version?
I'll have to point the finger, at this time, as some sort of app you downloaded. I can't tell you which one, as I just don't know. Half a million apps on the market, and even more unofficial apps.
I would suggest a factory reset. (back up your critical stuff), and see if the issue remains.
I don't know if you're rooted, or running a custom rom. So I at this time, will say you're not.

First of all sorry for the late reply. Was very busy. Please find my comments in red.

I had this problem from day one. I didn't suspect it as a problem of the tab.
And By the way, what is your current Android version?
current version is 3.2.1
I'll have to point the finger, at this time, as some sort of app you downloaded. I can't tell you which one, as I just don't know. Half a million apps on the market, and even more unofficial apps.Since this problem was there from day one I don't think it is a app problem
I would suggest a factory reset. (back up your critical stuff), and see if the issue remains.
The only thing that I didn't try due to limited and expensive data charges in Sri Lanka. Can't spend 5-6 hours re downloading everything
I don't know if you're rooted, or running a custom rom. So I at this time, will say you're not.
It is not rooted and I'm not running a custom rom.
Since it is still under warranty I'm thinking should I send it for a replacement.
Appreciate your thouths on this matter.

Try this..
go to settings
Date and time . Look at the Set Date and take note
Toggle off the Automatic date to off .. (un check)
Set proper time and time zone . but change there formats
change the hour format
change the select date format..
Shut down your tablet.. Then restart it.. This might sound useless. But if its a error in the software that controls the clock hardware. This might trigger it to reset. We used to have this issue on the old AMI BIOS CHIPS.MOSTLY on asus main boards. of course try a couple times.. because of the date being so far off it sounds like error in what ever controls the time and date.. Not a android tech . but im guessing the boot loader controls the date.or looks at it at the least..
only other option is to root . install cwm thru acer recovery installer.. DO a backup . with cwm and titanium . that will allow you to not have to re download all of your apps.
As i said the above is likely to not work.. but i know it was a issue on some old old main boards. YOUR FACTORY INSTALL COULD HAVE A ISSUE. Just never seen this with clock....
Good luck and sorry for being so long winded.

Thanks for your post. I'm still unable to get this date corrected. Tried it around four times and still no luck.

I'm just out of guess's on this one. Never heard of it before.
But you're better off taking it back for exchange. Considering it's happened since day one, and you haven't rooted.
Don't they have free wifi in Mcdonalds over there? Or try around the tourist type areas. Cafe's and such. Usually they try and kiss the feet of the tourists.

WOWEEEEE if Moscow desire can't fix it. It must not be repairable. Giggles
I to agree send it back has to be hardware Fail.but you are welcome to blame it on me

Thanks Everyone. I will talk with the local Acer agent and see if I can get a replacement.

If your planning on getting a replacement you will have to re-download everything also, which is your reasoning for not doing a factory reset to fix the issue to start with.

I finally mustered the courage and did a factory reset. I had all my data wiped out. Took a long time to get my most used apps.
Well the thing is it did not solve the problem. Still when my tab starts I get the default date and time 1/1/2009 @ 5:30 AM.
One strange thing I noticed is that when I do a restart with my ac adaptor plugged in, the date and time are correct.
Just wanted to post so that it might help someone who's having the same problem.

Bluetooth and Wifi broken

I have absolutely no idea what is going on with this. Currently when i try and turn on bluetooth it will sit and think for about 15 seconds like it's turning the radio on, then just fail and go back to thinking the radio is off. When i try to activate wifi it does the same, but says error.
I am running neutrino 2.7, but was seeing this on 2.6 as well. I did a full wipe and re-install last night, and installed apps one by one to try and find what broke it. I thought i had identified google voice as the culprit, but with that uninstalled and almost no other apps installed bluetooth and wifi broke this morning.
if i flash a radio it will fix it maybe once in 5 tries, and only for about 20 minutes or so, then it fails again.
this started last week around the same time AT&T started throttling my data for going over 3.5gigs. No idea if that is related.
any ideas, things to try, etc?

Make a backup and flash the stock rom and stock radio for that rom, see if it still happens. I've read of others having wifi and bluetooth problems, you may try reading in those threads.

Problem!!
you resolved the problem??? any idea???

nope, not yet. I've tried other kernels, and other versions of neutrino (was on EE, tried GT), nothing. Even with a clean wipe it's being dumb.
Downloaded the stock AT&T rom in fruitcake form, going to try that next.
From some reading i think there might actually be some phones with a hardware defect where some soldering wears out and starts messing up the bluetooth/wifi. I'm praying that isn't my phone because i'm well out of warranty.

i have the same issue on CM9 as of yesterday. no amount of wipes or different CM9 roms helps, haven't tried any GB roms yet though.

check this thread:
http://forum.xda-developers.com/showthread.php?t=1205775&highlight=wifi+error

i've read that.
flashed stock AT&T rom today, still have problems. not amused.
backing up my data, formatting all sd cards, wiping everything and trying again.

I'm with this problem too, Im running morrisoft rom since last month and I didn't any update, change configs or flash anything before It starts, so wierd...my wifi+bluetooth was working at night them in the next day it wasn't anymore lol..
(it happened today btw)
i ill try change my rom and see what happens...

same issue on a completely clean wipe. pretty sure at this point it's a hardware issue and not software.
I'll try the "fix" posted in the other threat at some point.

clean wipe has no effect. Wifi will sporadically work, bluetooth won't. I'm pretty sure based on how inconsistent the issue is this is a hardware issue. Not amused at all. No warranty left on this phone, and no upgrade until october.

This must be a pretty common problem. I had the exact same issue as OP, tried everything to fix it and nothing. Thankfully, I had an upgrade waiting for me. I tried to send mine in for warranty repair but no dice because of the bootloader being unlocked. (I even flashed it back to stock so that it didn't say "UNLOCKED")

They didn't want to repair it because they knew it had been unlocked? Are we talking about motorola?

same thing happened to mine..... it was a hardware issue, had it replaced...sorry..

Could be a brick, Could be hardware...

A Little History: :silly:
I have been running i9220ZCLP1...known bad kernel since whenever it was first available, April I think. Anyways, acquired that through flashing Rocketrom v5, according to the instructions provided at the time. Everything worked fine, other than contacts crashing and the wlan some times not enabling until reboot...common issues, as far as I've seen on these forums. One thing to note, is that unless the instructions at the time asked for a full wipe after flashing 5 (I'm almost certain they did not), then there has not been a full wipe performed while in this kernel.
The current issue:
The other day my phone froze on me...months after flashing and having used this kernel, waiting for something more solid to come out. After it froze...holding the power button turned it off, but the phone would not boot afterwards...to ics, to recovery, to download mode, nothing.
After some fiddling, I realized that it will charge and once it buzzes and the screen comes on showing a full battery, I can turn the phone on and it will boot...then freeze after getting past unlock screen. Or freeze and go black in download mode...didn't try recovery, wasn't interested in it at the time, but I'd imagine the same.
After removing the battery for a few days, then plugging it in til full charge notification, I was able to get it to boot again, where it froze at the boot screen, but went dark. After one more full charge...oddly, like a minute later, it booted to ICS fine and worked for 24 hours or so.
Now:
With a mind to flashing away from the bad kernel, I restarted the phone tonight from the menu in ics... it booted fine, so I left it plugged in to get a full charge and came back to a phone, screen still on, that shows same battery % as when I left it. And I'm back to where I started with this problem, powered off after holding power button a few seconds and now nothing.
Waiting for a full charge again, to see what happens...I'm guessing/hoping I'll be able to get it to boot again, with some more fiddling...
My question is whether this sounds like it's hardware (battery etc) or software (bad kernel etc) that is causing the problem.
If I can get it into download mode...plugged in, obviously, should I try OdinPC to a safe kernel?
Thoughts would be awesome. :fingers-crossed:

How about flashing stock GB via pc odin first and getting safe?

+1 I've read a few people on ICS having charging/battery related issues over time. Worth seeing if it still happens on a gb kernel.

Hmm, but how to get there...GB and all.
So now the vote is software. Any idea why this would happen much much later? No battery issues at all, just suddenly.
Maybe I'll buy a battery.

[Q] i9500 randomly reboots, wifi doesn't work and other problems

Hi, I bought my GS4 i9500 around 2 months ago, and few days ago while I was listening to music, someone called me and I noticed that the phone was a bit hot. I'm not exactly sure that that was the source of this problem.
Anyway, when I put the phone down, it didn't work, and after a few seconds it rebooted.
Ever since it rebooted it keeps doing problems - it reboots once in a while, the wi-fi doesn't work, and the touch is delayed sometimes (it doesn't respond for a while, and after a few seconds it suddenly responds to all the gestures I did over the last few seconds.).
I tried factory resting it, change frimware, clear cache and everything, and still nothing worked. It still does these problems.
I took it to the store where I bought it and they flashed it, and still it didn't solve it.
The problem is I rooted the phone, and I'm afraid the warranty won't be accepted if I send them the device.
Anyone knows what the problem might be?
Sorry for my bad English.
Thanks.

It worked for me to go fully back to stock. Maybe give that a shot,

Noop, sorry man. when i did go fully back to stock it went off... i think its a warranty problem here.

well, i'm currently dealing with the problem too, it automatically boots itself, my reception goes off, eventough im not in a dead spot. but: it only happens if im on ~20% battery. i think its a softwaresided problem. im running on the normal stock touchwiz with android 4.2.2.
im gonna send it to the operator, maybe it really is a warranty-sided problem.

Sent to operator, unfortunately the warranty has been expired (probably because I rooted), and they want ~450$ to repair it..
Hopefully ill find some solution.

Fast charging not working and phone charging extremely slow

So I'm on the 935u for about a month and a half now and had no problems. All of a sudden today my phone stopped fast charging and is in fact charging extremely slow. I was on zero percent and put my phone on the charger around 6pm. It is now 1am and I'm at 49%. I'm thinking this is a hardware problem but before I bring the phone to Verizon I wanted to see if anyone else had this prob? Also will version give me a hard time since Im on the 935u software?

If you're worried about Verizon giving you a hard time then flash back Verizon's firmware. But before your return it I would test out the functionality of fast charging and see what happens. If it works then why return it? Also if it works then I would say flash back to the U firmware and test again. Don't restore old settings or anything.
Or you could just start from where you are now and flash the U firmware over your current U firmware to reset any setting changes you have made. I know, it's a lengthy process but it's better than going back to the store and dealing with Verizon.

turns out there might be an issue with my usb port. My phone won't even detect I connected it to my pc. It just shows charging. No options come up for media or anything. I can't even reset my phone to stock rom. This sucks.

Rooted? If so, you have to go into the developer options to change the usb mode. There is no pop up on the phone, it defaults to charging mode.

Are you sure the cable is a data cable? If it's the stock cable then try to get ahold of another Samsung cable. Someone else had a similar problem with their S6 on another forum.

yep, its the stock cable. I plugged in my wifes s6 on it and it worked perfectly.

Anyway to flash stock rom without the use of odin or usb?

Weirdly enough, I was having this same issue yesterday. Couldn't figure out what was going on - then tried a different cable and it charged normally. I think those Samsung cables aren't built very well. Ordering that PowerLine+ from Anker.

so verizon exchanged it via warranty no issues. They just checked to see if it was rooted whichi it wasn't and confirmed that the usb port was defective. All is well in the world again!

I was having this problem about 4 weeks ago. I tried everything but nothing worked. Rebooting would help for a bit then it would slow down to a crawl when I tried to wireless charge. Then I recalled I had taken an update recently and hadn't done a factory reset. I had traditionally always done one because in the past android was always buggy if you didn't. I thought android was supposed to have gotten better about taking updates without needing a FR so I had decided to do one without and had no problems for a while so forgot about it. When I realised that was the issue I saved as much as I could with Helium (normally I would use Titanium but I don't like the root method so for now have remained stock) and performed a FR. Since then I have had no issues and wireless charging works as expected.
TLDR: Backup everything and perform a factory reset.
