[Q] Problem LTE Galaxy S3 Wifi and Mobile Internet - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hello everyone,
As the title says I have a problem on my S3 (i9305).
First of all I want to know that it has been dropped or anything,
I put the official version 4.1.2 (the DBT for Germany was the latest then) instead of 4.0.4, rooted + busybox + modem network Vodafone Romania (XXBLL5) and it worked just fine until yesterday.
I arrived at work I checked my mail via wifi network, I disconnected I put on charger and after an hour I removed to make some mail and then give it to initialize wifi stupor show he wants to start and stop and did not want in any way to start a (looks like starts and stops).
Good now seeing that I got it and I somewhat empirically and did the following things:
-clear cache, wipe Dalvik, reset permisions - still did not work
-restore the Nandroid for wifi - did not work
I managed to got mad and threw factory reset - still not working height
-continuing with nervousness I flashed phone about 4 times with different versions 4.1.2 and version 4.3 but bootloader of 4.1.2-
Normally he did not want none and some gave the "camera failed" error.
All versions have been flashed after wipe cache, dalvik and factory reset so I say something to remain excluded from one another.
Now I'm on a Vodafone version 4.1.2 on sammobile after I haunted a bit on the internet I saw that its more people with this problem and someone had an alternative after you rename the file "wpa_suplicant.conf" in root / data / misc / wifi.
I did this and go but it is something temporary peak for once stop or restart your wifi is not working and another thing
mobile internet does not work without you come in APN and reset its there.
Sorry I did read both but I do not understand the phenomenon and to solve it because there can not be a hardware problem but rather a problem or write permission on the root folder.
And now comes the question: is there a solution to my problem or a way to see if some parts are protected to rewrite or corrupt?
Sorry for my english i use google translate.

[Q] Galaxy S i9000 won't factory reset and force closes frequently - now with logcat

Hello all,
please forgive me first of all because I've had very little sleep due to this issue. And its a long thread, but more detail is better generally I believe.
First, some background, and unfortunately, it starts with my wifes phone.
My wife has a Galaxy S GT-i9000 on Orange in the UK. She has had it, probably about a year maybe at most. She has a few apps that she has downloaded but nothing major and on first looks when I got it nothing I expect would cause this issue, just facebook etc.
My wife came home and said, my phone keeps coming up with a message saying force close. Ahh, I thought, some apps gone nuts, but alas, it appeared to be many apps including Maps, Google Upload (I assume this is a system process), Facebook Katana and many more, probably about 20 Force Close messages pop up one after the other and it lags whilst trying.
Odd, I thought, I also noticed the icon for one of the apps on her homescreen had changed to the default White and Green one with the android on it.
I suspected something had gone wrong (obviously), I asked if she had rebooted it and she said she had. So, I rebooted it again, just incase. Same problem.
I then thought it might need an update, it was running official Kies 2.3.3 (or was it 2.3.4, I forget) so I plugged it into my netbook and ran Kies, had to update that as it didn't have the latest application update. I then started the firmware update, after backing up the phone using Kies.
Halfway through the update, Kies popped up a message saying something went wrong and that I had to unplug the phone, take out the battery and reboot. Odd, I thought as the phone was telling me to not doing anything. I waited a minute, nothing further happened, so I did this. Then I got the Black Screen of Death with the phone, the dots and the computer screen.
Crap!!! I thought, I managed to get into Download mode, and reflash it using what I believe was an official ROM using Odin. I then rebooted, and found that it STILL had the data on it and it STILL was doing the force close. At least I had it back to "working" though so I was mildly happy.
I then did a factory reset using the menu system, erased the USB storage (there is no external SD card in her phone) and rebooted, still force closing but prompting me to setup again. Weird. I went through the setup slowly, as every second or so a force close would popup, then when I completed the setup (which still had the wifi settings, account settings etc in it) the System Setup crashed with Force Close. I then rebooted and got to the Home Screen, but still crashing.
I rebooted and used the recovery screen to clear the cache and factory reset, despite the warnings I will lose everything, nothing was wiped.
I tried to update using Kies again but it tells me that the firmware/device is not supported. I am now trying to see if I can use Odin to install a Kies supported firmware. So that I can then try an update using that again.
Anyone got any suggestions, at present, my thoughts are, I was going well within the realms of warranty up until I reflashed it using Odin to try and get back in as I'd only used Kies to update and the issue "just started happening" without my missus doing anything.
There are no signs of damage on the phone and she tells me it was just sat on her desk all day.
So, my question is, what now? I'm of the opinion based on the above that if I can't reflash a warranty supported Kies update, then maybe a custom ROM will be worth a shot to see if its a hardware failure or if its software. I just have never had an issue like this with my HTC Desire and I've ran many custom ROMs and standard ROMs on it.
I do have the .tmp file of the update Kies downloaded, and I also have a Binary folder which has some file inside a couple more folders but its not a .tar or a .zip because when I try renaming it (after a copy) it won't open.
So, suggestions on a postcard, thanks if you got this far through this nightmare. All help massively appreciated.
Edit: it appears to be the same issue as this: http://forum.xda-developers.com/showthread.php?t=822238
I'll try some of their suggestions. Today I also did the *2767*3855# today which I found after a bit more searching. Same problem after a reboot. Force close and data still there.
I've tried and tried again to do various solutions for this, I've even ran a logcat using adb to see if I can see the problem. I suspect its a Dalvik Cache issue in that its unable to write to it for some weird reason.
I've downgraded it to Froyo following this guide: http://forum.xda-developers.com/showthread.php?t=1100906
It now detects in Kies and offers me a firmware upgrade. I suspect it will die again though if I try due to this Dalvik problem.
Wiping cache does not wipe the cache. Everything still appears to be there on reboot as mentioned above.
Here is a copy of the LogCat with Java errors all over it: http://leenukes.co.uk/downloads/logcat1.txt (its quite long)
I guess nobody knows. Today I will speak to Orange to try and get it fixed or replaced.

We've been told it is beyond repair. We will see what they say when we go back into the shop. Its still in warranty so I don't see why they won't replace it.

I have a friend with a Galaxy S from Orange Romania and suddenly the phone kept showing Force Close on every App. He had 2.2.1 if I remember right. He whent with the phone to an Orange Shop and they only do a factory reset but data was not wiped.
So what i have done for him:
- start the phone in Download Mode
- start Odin with repartition check and XXJVT (2.3.5) firmware with 3 files (code, phone and CSC) + pit file .512
- after reflashing the phone does have all tha data, so i resarted in Recovery Mode and done a Factory Reset and a Cache Wipe
- i flashed Speedmonde Kernel k16.10 and do again from Recovery Mode a Factory Reset, Cache Wipe and Davlick Wipe.
On reboot the phone was CLEAN. No force closes for a week now.
Sorry for my English hope it helps!

Sound advice there mate, other thing I would have done is in recovery mode before the ODIN flash I would have format sdcard, making sure you have removed BOTH the external sd and the sim card, as it can wipe them as well.Then flash through ODIN as per instructions above.
Using JVT I would flash either speedmod or semaphore 2.1.1 which I personally use.
Happy flashing!!
turns out it was water damage and some parts corroded.
Its going to be claimed for on insurance.

Hello all,
the phone came back from repair yesterday, yay!
the phone now however, doesn't appear to lock onto a mobile signal for very long. Boooo!!!
After sending off for repair using insurance, we got the phone back yesterday but it now appears to be broke in another way. It won't lock on to a mobile signal, wireless is fine but data network and sometimes just mobile signal is patchy and keeps dropping.
I've just reset it to factory defaults, same problem. What I did notice, which is odd is that since it came back from repair, its now unlocked and I can put another networks SIM card in it, same issue there too so I know its the phone now.
I'm going to scour the forums to see if anyone else had/has issues like this, it is running the latest firmware now and a full wipe really did fully wipe it this time, as opposed to last time with its issues due to water damage. One step forward, two steps back?
Its going back to the insurance company. Especially as Orange were suggesting that we pay £70 for a new handset.
Absolute fool I had on support today, yesterday I at least had someone sensible.

Sounds like a modem issue, where the techs at Orange put in the wrong modem for your firmware. I did the same thing when I upgraded from Froyo to Gingerbread.
Alternately, it could be a broken external antenna connection as a result of the corrosion from the water damage. Google "no signal fix" and look for a site that ends in .uk
Just a thought for others who come across this problem.

[Q] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

S3 i9305 - problematic wifi.

Hello guys,
I just want to share this problem with my S3 LTE i9305, this unit came from singapore (singtel), and im now using it in Cebu, Philippines. However i am having too much trouble with its wifi always getting Authentication errors (when i was still in stock firmware).
I should say i can rule out that my wifi hardware is defective, because I was using the wifi yesterday whole night in our house. downloading stuffs from play store, browsing, facebook and etc.
This is what i already did:
1. downloaded a Hongkong firmware (official samsung stock firmware) flashed with odin with no problem. hoping that the wifi issue is just a corrupt base firmware.
- still wifi is problmatic
2. Im on Cyanogenmod 10.1 4.2.2 Jellybean
- all functions are okay except for the wifi
WIFI SETUP:
keep wi-fi on during sleep: always
wi-fi frequency band: auto
wi-fi region code: usa
wifi optimiation: unchecked
It can seem to detect new wifi with strong signals but whenever you connect to it the signal 'literally' drops to one bar, and stop doing the connection.
the problem is intermittent, meaning:
sometimes it works, sometimes its not - and there is no definite time when it works and when not.
here are the details of my current device:
Baseband version: I9305ZHBMI2
Kernel Version: 3.0.64-CM-g9c2e2b; [email protected] #1; mon sep 23 15:03:19 pdt
Cyanogenmod version: 10.1.3-i9305
Build Number: cm_i9305-userdebug 4.2.2 JDQ39E; eng.jenkins.20130923.145024 test-keys

hello! sorry about early bumping.
with wiping phone flash stock rom <<-- how do i do this? and not corrupting any vital stuff inside my phone. I heard that EFS is a very important.
update:
if you're talking about these:
1.wipe data/factory reset
2. wipe cache
3. wipe dalvic cache
i did those stuff 10x already...
PROBLEM is INTERMITTENT: sometime it will connect just fine, sometimes not. << how am I going to work around this problem?
is there any way to low level diagnose the wifi system?
could it just be the hardware? - if hardware then there shouldn't be times that it can connect fine
could it be the software? - where to start?
How i wish someone can help me fix all these intermittent problems I am encountering with the wifi.
EFS etc its all in the Faqs and Guides .

Hi, i have been reading those giudes, and i havent encountered any special method of wiping as what you say... I have used odin to flash like 5x already, got into cwm wipe data, wipe cache and wipe dalvik cache...
I already have a backup of my efs in .img format, using terminal.
Can you walk me through?
Wipe phone flash stock rom and test .
I believe flashing via odin using stock samsung rom will wipe the flash. Is that correct? Or do you mean to say format the flash chip first before flashing with odin?... Im not quite sure how to do that.
Right now im using my celfone posting this message. Its just that this fone doesnt connect to other access points where the rest of wifi devices connects fine.
if you are referring to this guide:
http://forum.xda-developers.com/showthread.php?t=1911726
i have done this many times already.

I have tried alot of different ROMS already and the problem persists.
Could this be hardware related?
are there people whos got similar issue?
It can connect to wifi right away if you're 2 meters line of sight of the router/access point.

Please share wifi root folder structure

Hy, please i need someone to share his wifi root folder structure, screenshot and even better files/folders from
"/etc/wifi",
"/data/misc/wifi",
"/system/bin/wpa_suplicant",
"/data/.cid.info",
"/system/etc/wifi",
"lib/modules/dhd.ko",
"system/lib/modules/dhd.ko"
with root explorer or any kind explorer that show permisions&owner rights.
I need this information because i have trouble with wifi not turning on just trying to turn on(gray icon) and immediatly turn off.
I tried everything , let me share what i did:
-turn off and on the phone
-remove battery for 1 minute
-clear cache, dalvik cache
-factory reset from CWM
-factory reset from phone
-nandroid restore
-flash again 4.1.2 for 4-5 times (different stock roms with different kernels)
-flash custom rom ( different kernels)
-restore again data from nandroid
I managed to work wifi at one moment but at first restart i loosed wifi, so after i read a lot of forums,tricks i de
decied to flash again 4.1.2 ( bad move from me) and let KIES update my phone to 4.3. ( i read this thing on one forum and that guys said managed to work his wifi) but nothing happened.
Then i do the same thing like before on 4.1.2 : power off , clear cache, factory reset, flash again, etc.........
At one moment the wifi managed to work but for 5-10 minutes after that nothing.
Im very sure is not a hardware problem, more software problem kernel + modem or anything else.
Phone is GT-I9305/ TGP ver 18.10/ Agni pure stock 3.8
So please, please someone help me with that info.

Hi. I have the same problem.
Did you solve it anyhow?
Unfortunately I could not solve the problem alone and I resolved to a service center where we changed the wifi chip because it was broken.

Now i don't need files anymore, aparently was not a software problem was a hardware problem.

gettin No signal cuz i screwed up - fixed

So,all was well with my z1 and somehow my subconscious thought that I something should be screwed up.
Well,I was getting really bad signal reception in my area for 3g since i barely got 1 bar(though i got 4 out of 4 bars for 2g)
.
Now,I typed in *#*#4636#*#* in the dialer >> Phone Info >> Menu key thingy>> Select radio band(well obviously,i thought that if i could unlock more bands,then i could connect to one with more...power) >> Only one option was avaliable--> "USA BAND"....So much for unlocking new bands.well i selected the 'usa band' anyway thinking that is was the default option,
BOOM..there goes the signal reception and i couldn't get it back no matter what i tried: I tried factory resetting,I tried manually factory resetting,I wiped Dalvik Cache n Cache. I reflashed the baseband via flashtool.AND STILL NO SIGNAL( I blame sony for including stuff like this in their phones)
I searched a lot for fixing this on the web and i found that many people had the same problem as me but i found no answers as to how to fix this.
SOMEBODY plz help me,ANYBODY plz help me.
UPDATE: ok, after flashing a multitude of different firmwares via flashtool,i somehow finally got my signal back...yah. So if this happens to anyone in the future,...then go crazy with flashtool
A full reflash is the only way I have come across. You can hardly blame Sony, they didn't give you the code (which works on pretty much any phone).
i fixed this problem, reflashing only kernel (stripped file for LB)
