Hey guys,
I hope someone will know the answer to my problems, I'll try to keep this short. (English is not my first language so excuse me for any mistakes I make).
Around 2 months ago I couldn't connect to my wifi, I tried everything, but eventually I thought the only solution was to factory reset my Samsung Galaxy S2.
That turned out to be a stupid decision. I made a back up of my media files, so those were safe. But the option to make a back up of your contacts using google didn't work, so I lost all my contacts, whatsapp messages and text messages.
Factory resetting my phone was the solution to the wifi problem though, so I was happy with that. And in the mean time I've gotten a lot of my contacts back, so that's not that kind of a big issue to me anymore.
But now I have a new problem. My phone can't update it's firmware anymore. I've tried using the update function from the phone, but it says it can't connect to the server. And using KIES, it says that the phone can't be updated as well. Now it's running on 2.3.5 and I'd really like to get the new OS available. (This is problem #1).
Problem #2 is the fact that in the last few days my battery has been incredibly weak. Normally I could last 1,5 days to 2 days with a fully charged battery, but now it seems to only last about 4-6 hours. The phone seemed to be a lot warmer as well.
I've tried to find a solution for problem #1, and all I could find is that maybe the factory reset changed the settings of which country your phone is from (I'm from the Netherlands), and that this is the reason why I can't update my phone.
In the thread I found they were talking about using #1234# and checking the codes there, but when I use this my phone displays (translated) ''connection problem or wrong MMI-code''. So I can't check if the data changed after the factory reset.
What should I do next?
Thanks in advance.
Hello there mate.
Im not a dev or something but from different cases that i've seen with many GS2 phones i think i can help you ( i hope at least ).
First of all i think you can easily update with odin to the new ICS firmware Samsung has for GS2.( If you use windows 7 run as administirator )
You can find many tutorials on youtube of how to do that.
Remember to back up all of your data before updating because they will be erased.
After installing fresh ICS firmware (official 4.0.3) you will need to do a factory reset.
Now for your second problem i think it might be an app problem which requires power from your CPU and that's why your phone is overheating and the battery is draining that fast.
I would suggest after using an app to kill it via the task manager so it won't run at the background demanding dedication from the system.
If that doesn't work also try re-installing all of your apps.
Hope you find this kinda useful friend and solve your problems.Take care
Thanks for the reply!
But before I upgrade with odin, don't I need to know the codes (representing where your phone is from etc.)?
I've found them under settings. They are:
Baseband: I9100XXKI4
Kernel version: 2.6.35.7-I9100XWKJ3-CL647431 [email protected]#2
Build number:GINGERBREAD.XWKJ3.
And how do I backup all my files? Especially contacts, text messages and whatsapp messages?
No problem ! Im glad that you found my info somehow helpful!
Now as i said earlier im not that kind of expert so giving the current sittuation i don't really know. You should search on the internet for your firmware available for your country and also you can search at sammobile.com then go to firmwares then select the Smartphone option then Android and you should be good to choose the firmware and download it for your region/country. ( Terribly sorry for not giving a link but xda forums are saying that i need more than 10 posts to post a link.
So good luck with that one :good:
I never tried it myself but i've seen that people backup their contacts,texts and apps with KIES so you should give it a try :good:
Either than that,this is all i know and im really sorry if i can't help you any further as im new here too
Alright thanks for the help.
I made a backup of my contacts, whatsapp messages and text messages on my SD card. I'm almost gonna start using Odin. (You don't need a rooted device in order for Odin to work, right?). And I also only got a .tar file from the downloaded package from Sammobile.com, is that all I need?
I'll post the results
Yes Odin will work with unrooted and rooted devices!
I don't know if that's the file, i would do a little search before updating about the files and remember to watch a video on youtube to help you with the process !
Things to remember : If you are on windows vista/7 run Odin as administirator
After installing the firmware do a factory reset / clear cache
Good luck! I hope somebody more experienced than me will help you better than i did . :good:
Haha alright thanks for the help.
I used Odin this afternoon, with succes! I updated to 4.0.3 (only using the .tar file) and after that I factory reset my phone.
Also, I managed to succesfully retain my text/whatsappp messages + contacts, so everything's fine.
I'm going to try out my phone for a couple of days and I'll report if anythings wrong with it.
Really glad that things went in the right direction for you
Just a quick thought now, our Samsung Galaxy S2 will get a new update to 4.0.4 which is reported to be far better than the current one and will be available on the upcoming weeks so be prepared to do another update
But anyway you did a great job! :good:
I recently flashed CWM onto my uncles GS3 and rooted his current rom. I made a backup and then tried out a new AOSP rom, which we decided not to keep because my uncle did not like it. But now, returning to the old rooted stock rom, every time the phone disconnects from wifi, it completely freezes up on the lock screen. Pressing the lock button does not shut off the screen and instead just locks it. You are unable to unlock it as the phone completely freezes up. The only way to get into the phone is to double tap home to get into the voice commands, and then go to home from there.
But even after that the phone continues to freeze. I tried another ROM on his phone today, but the problem still persisted a while later. It all happens when the phone is connected to wifi, and you walk out of range. After which the phone starts to freeze up.
I'm totally unsure whats going on. I just flashed the rom again, and we are trying a clean slate with no restoring of any data. It may have started to happen after we installed root browser (just as a guess), but we could be completely wrong.
If this continues again on this rom as well (which is Revolution HD) Im going to go back to completely stock (rom & recovery), and hope it still doesn't persist there. If not then I am out of options, and I have no clue what to do.
Any help would be GREATLY appreciated. We spent so many hours today trying to resolve this.
Thanks!
Usualy WiFi problems are kernel related. Have you tried Siyah or another custom kernel?
If this will not help than returning to stock with all wipes is the best idea, this should resolve your problem. If not, than you can try to reset router or set static IP for s3. Also try to remove WiFi setting for your home network in the phone and set it again manualy or via WPS mode.

Thanks for the reply. This issue has been occurring between two different roms, so can the kernal still be an issue? Its happened with the absolute stock rom (w/ root) and Android HD Revolution.
My uncle said he would play around with the phone and let me know if it freezes again by tomorrow. If it does im going to wipe and stock.
Can anyone show me where to get the stock roms for the i9300?
I've downloaded and tried 3 different ones, but the phone never manages to boot up!

Same problem on Galaxy Note N7000, did your problem resolve by reverting back to stock because I've tried every possible option, to no avail?

Go into recovery and wipe the cache, I believe that was my problem.
Hi guys,
I have a huge problem. I had a stock GB firmware customized by Optus (carrier in Australia) on my S2 I then decided to change to the new ICS 4.0.4. I downloaded the stock unbranded firmware from SamMobile (Australia 2012 September 4.0.4 I9100XWLPW, I9100XSALP6, XSA) I updated using Odin. Before I did the update I reset the phone, did the update, it all went smoothly. After the update I reset the phone again and then proceeded to reinstall all my apps and restore my contacts, sms, etc.
The phone works and all functions on it work, however now very randomly the phone would totally freeze. The phone would be in standby, the screen would come on and it would be frozen. The screen stay on all the time and it does not respond at all. It will stay frozen until I restart the phone by pressing Home+power buttons to restart it.
After restart it all works fine for a few hours, sometimes a day and would just lock up again. The phone is not rooted and as I said i just changed the firmware from the Optus branded GB 2.3.6 to unbranded stock ICS 4.0.4 by using Odin.
Is there a way to find out what is causing the phone to lock up like that? Any suggestions would be helpful.
and then proceeded to reinstall all my apps and restore my contacts, sms, etc.

I made sure that I didn't restore any data apps. The only apps that got restored are the ones that get automatically restored by Play store.
I have disabled the live wallpaper that I had and it seems to have stopped the freezing for the moment. I will report on what I find out.
In the mean time if anyone else has a similar issue or has a definite solution please let me know.
Thanks
i know this is a resurrection, but don't see it has been resolved.
also found same/similar problem on another topic, but no resolution either.
couldn't find any resolution anywhere on the net, but possibly i'm just missing it (searching for wrong parameters?)
anyway, a friend of mine bought second-hand (third or even fourth hand to be precise) i9100 with 2.3.6 (stock KI3) on it. the guy who sold it to him said something like: "it works best on 2.3, on 4.x it's buggy".
it was working fine, but friend wanted newer OS, so we tried update. it didn't work, and i found out CSC was broken/missing. somehow i managed to repair it, and update was finally working, but was unable to find any for our location.
so next step was to find stock rom that would work on the device, and then i tried four different 4.1.2 stock roms from this topic.
after flashing it through odin, every one was acting fine, until couple of minutes after it started freezing or rebooting randomly.
then i tried flashing CWM, and flashing from sd card, but it was all the same.
wiping data, cache and dalvik cache, prior to flashing. wiping data after flashing...
nothing seemed to work.
GB works rock solid, ICS works better than JB, but stills it freezes or restarts randomly.
tried CM10, but all the same, except it works a bit faster then official JB. but who cares about speed if it freezes/restarts constantly?
back to who knows which build... freeze... samsung galaxy s2 - i9100... with yellow triangle... booting stopped.
so i decided to dig deeper, trying to find hungarian stock build (country we were told the phone came from) not being sure that KI3 is what the phone came actually with. i found 4.0.3, put it on SD card, wiped data, cache, flashed CWM, wiped data, cache, dalvik cache, flashed 4.0.3 from sd, wiped data, booted, entered location for updates - hungary. update found, hooray... downloading... installing... rebooting... working?
nope... it's worse than ever. trying to log onto google account. typing in email add.... freeze... switching phone on - freeze... thinking about... freeze.
i couldn't sit still. yellow triangle, all those reboots/freezes... at least i wanted that triangle gone, and without a JIG, there was only solution for me was to try triangle away. it wasn't available for download in my country from play store, so luckily xda was there.
somehow i managed to download it from the device, install it, click remove the triangle... it did it's magic, rebooted... and miracle happened!
no more freezes.
so i started torturing poor phone, benchmarking, playing games, listening to music.... it seemed stable for about an hour.
so i said to myself:
- it's possible that previous owners tried to upgrade it to newer firmware, and somehow screwed up the bootloader, which was fixed by this app? maybe that was all there was from the beginning? why not try putting 4.1.2?
and i did... took 4.1.2 spanish build from already mentioned page above, flashed it... and voila. working JB... torturing the phone... playing with it... hour passes, another hour...
friend wakes up... takes his phone in awe, starts playing with it.. we talk a bit... and then that look it just froze again!
from that moment on, the phone again starts restarting or freezing randomly...
and, yes, i still have no clue what could be the cause. it doesn't matter if wifi is on or off, if you're talking on the phone or not, bluetooth and gps are always off. only thing that he noticed is that it usually happens while he's using the phone (meaning: operating the digitizer or buttons). if he starts music playback and not touching buttons or screen, it will probably play for hours.
one more thing, but i doubt it would be the case. the battery in the phone is not original one that was shipped with it, but a quality replacement.
it doesn't feel as if the phone is overheating... so i don't know what else i could do with it.
for now, it's back to 2.3.6.
we both lost a week, torturing ourselves with this problem.
i don't know is there anything i could add more?
all suggestions are welcome.
cheers
Maybe try kernel cleaning script and try philz or siyah kernels.
You shouldn't have to flash a custom kernel so your phone won't freeze, but yes, you could run a nuke script in order to wipe clean all custom ROM's leftovers.
Try flashin' jb via mobile odin, see if it keeps freezing up on you. If so, nuke it up.

i'll try them out.
probably for the weekend, if not sooner. will report back here with info.
any other suggestions are also welcome.
thanks a lot.
cheers
ok, so here are some updates.
i finally got my hands back on my friends phone, and tried nuking remains of older flashes.
following that, i flashed stock spanish rom from above mentioned page, updated after installation to spanish update... and after a few minutes, sudden reboot...
so, went back to nuking, and flashed stock hungarian 4.0.3 i found elsewhere (mentioned in my earlier post. don't remember origin... if i find the link on another computer where i downloaded it on, i'll post the link). tried updating, says no updates found.
started torturing the device. it seemed solid, but battery reported it level was low, so hooked it up onto charger and all seemed well. but phone seemed a bit too hot.
after few minutes (this was all about half an hour to hour after flashing to 4.0.3), again freeze.
after rebooting the phone, battery was at 9%, as if processes were draining battery faster than charger recharged it.
so, i figured i gotta try original battery. so i switched his battery with genuine from my phone.
phone seems stable and less hot, for now.
still checking if it is going to freeze or reboot again.
it's about one hour since battery change. still on charger and using wifi and playing around with apps.
i'll check in with news later.
cheers
I have the same issue.but my battery is original.
What I noticed that the phone stuck when I receive an update notification.
Can I stop softwsre to ask for updates? ???
Sent from my GT-I9100G using xda app-developers app
^go to settings, about device, software update and detick auto update. that should stop it from trying to self-update.
ok, so here is an update to my friend's phone status.
currently on hungarian 4.0.3. about 3-4 freezes/reboots a day. sporadic connection breakups during calls. also, when we talk i can hear myself back. this brings me to conclusion it has to do with modem firmware. i found this topic, so i'll try putting that and see what will happen.
if that doesn't solve anything, my question is this: is there any way of knowing which firmware/rom was originally put on the device, since i don't know the real background of the device? i.e. some way of entering IMEI and finding out what should be on it?
cheers
EDIT: tried KH3 modem, no changes... i could still hear myself while talking to my friend on that device. also, it froze couple minutes later. going back to 2.3.5-2.3.6 for now.
so after couple of months, i finally got my hands back onto this phone...
gave my friend my phone, so i could play a bit with this faulty one.
i have played with it for a couple of days now, and here are things i've tried.
i received it from a friend with 2.3.5 on it which had triggered custom binary counter. he's been using it for couple months without any problems.
so i rooted it and installed triangle away again... reset counter, cleared and flashed hungarian stock (telenor) 4.1.2... random freezes again.
tried several stock roms, mostly hungarian ones (4.0.3, 4.1.2). even reformatted with .pit file... random freezes.
reformatted again with .pit and put XXLSJ, installed stability test and let it run...
cpu stability test 15.5 hours no problems, no freezes. then i realized it didn't have a sim card, so i rebooted phone and installed sim card. let it test cpu+gpu for 9 hours... no errors, no problems, no freezes.
so i thought, maybe it's all fine? but it wasn't! as soon as i took phone into my hands and started going through menus it froze!
so i tried SGII_repair, rooted and did "repair"... but nothing changed... still random freezes.
if i just let it do the stability test, it'll probably work forever.
things i've noticed:
- serial number is wrong format (14 hex digits instead of 11 alphanumeric)
- during stability test, cpu frequency dropped from 1200 to 800 mhz (maybe because it was getting warmer? 42-43C during cpu only+charging battery, and about 39-40 during cpu+gpu test)
i tried to find out which firmware is latest according to serial number via kies, but it gave me error.
i know it's from hungarian market, but don't know which exact part of it (branded or not).
don't know what previous owners did to it, and don't have backups of original efs or anything original.
i just want to make it work, don't care much about custom firmwares. i'd be happy even with unrooted stock... just for it to work!
i have no ideas what else to do.
anyone?
finally, as i couldn't resolve the problem, i returned phone to 2.3.5 and sold it as is.
thanks to all people who tried to help.
cheers
Good afternoon all,
I have recently updated my Samsung Galaxy S3 via kies to Android 4.3. I couldn't do the update over the air as it was rooted. I had to go through and root my phone again through Odin and again all that went fine.
However since doing this I have had to restore my device 2 times as it shuts down every now and then and I find I 'lose' some apps...mainly games, which I find annoying. It also wipes any saved text messages.
At first I thought it was only losing apps that I'd downloaded through other means (i.e. not Play) but it appears not. I still have the apk files stored on the phone and have tried to re-install them but I get a message of 'app not installed'
Can anyone tell me why this is the case? As I have previously said it has only been since updating to Android 4.3. Not sure if it is due to rooting my phone (i'm guessing not).
Any help will be greatly appreciated
Chris
!!ALL QUESTIONS GO IN THE Q&A FORUM!! OR THEY MAY BE DELETED
Please use the red report button and ask a mod to move the post.
See multiple posts re OTA and root problems.
Suggest factory reset if that does not fix then flash stock 4.3 through Odin .
I know that I can't do OTA updates... My problem is that the phone will restart, without warning and when it reboots I have lost all my text messages and a few apps. Trying to reinstall the apk files gives me the error 'app not installed'
I have tried factory reset both through the recovery mode and the system settings, but nothing resolves it.
My phone is rooted and runs Android 4.3 which was updated through kies.
The apps it loses are games so that's not a major issue... It's all the text messages.
I have a very similar problem, phone always shuts down and restarts on it's own. A couple of times it has lost some apps but usually it just starts up again fine but it's very annoying. Sometimes it gets stuck in a boot loop too.
A Google search for random reboot or random shut down brings up a lot of results but no solution's, so it seems to be a common problem. It's not just the stock rom either as it still does it when rooted and running other roms.
TL;DL: Phones 16gb storage changed to 128mb overnight. None of my files/apps/pics accessible.
I have the international version for the S3 (GT-i9300) with 4.3 stock firmware installed (rooted)
I woke up this morning and looked on my phone to see that my primary launcher, nova launcher, had been reset to the original layout when you first install it. I was confused so I restarted my phone and it went back to touch wiz. But now none of my apps, files, pictures, etc. from the internal memory on the phone are accessible. It seems like it went back to an old backup I once had due to the lack of my newer contacts on board.
When I connected the phone to my PC it only shows 127mb/128mb where as on the storage settings it shows available space of 5.75gb/16gb where all the non system memory are labeled as miscellaneous.
In application manager it shows all my apps i used to have but now they all have the android logo and 0b of storage.
The phone also prompts a message every couple seconds saying clock is not responding.
No idea where to go from here seeing as i can't even access all of my internal storage... Would appreciate some help on my situation, thanks in advance!
EDIT: Tried factory reset, tried installing play store apk, tried flashing an updated firmware, tried booting into clockwork recovery.... all with no luck
Flash full stock firmware with Odin then factory reset.

Thanks for the suggestion. I flashed stock firmware and ended up doing a factory reset through the recovery menu. All seemed well as my phone stopped heating up like it used too, battery lasted longe and all the symptoms I was facing stopped. Unfortunately when I woke up this morning the phone factory reset itself again. Same symptoms as before but this time I can view files, even though everything got deleted...
My question is now should I just flash a different rom like cyanogenmod? So far for the past 2 years I've only stuck to the stock rom and I've faced nothing but troubles. Wondering if I might face the same thing once I convert.
Thanks!
