[Q] Computer cannot detect G850F - Samsung Galaxy Alpha

Something has happened to my phone (about a week ago), and now it cannot be detected on the computer (in touchwiz).
I have tried it on many different computers, but nothing.
When I reboot to recovery or download mode, it can be detected, but of course it is still an issue in touchwiz.
This happens on Eudemony Rom Alpha 4.4.4, and on the stock ROM 5.0.2 (dirty update).
Has anyone got ideas?
Thanks

Dial *#0808# from your phone Make sure Phone USB is set to AP and USB SETTING is set to MTP OR MTP+ADB
Have you tried flashing Stock 4.4.4 rom from sammobile then, clear dalvik clear cache and factory reset. After this delete samsung driver and kies from your Pc AND reinstall then connect your phone.

It maybe because of the drivers have you installed samsung drivers for mobile devices or samsung kies(if you install kies you need to disable it before using odin)

Try installing the latest samsung kies available. It will come with the required drivers. What OS are you using ?

i'm using window 7..
You said that you tried to root but quit.Hope you didnt try to root with a i9100 kernel on your i9100G cos i dont think they are compatible.Re-install the latest version of kies and if that doesnt work then re-flash your firmware and try again.
well... I have this problem before, me just trying using other port the problem was sloved... (tips: do you unlock you phone before connet to pc?)
Other answer from other forum
Fist:
I) restart you pc,
II) on you kies
III) turn off you phone
IV) connect to pc
V) got driver now?
if still cannot.. try
a) wipe data and cache on recovery mode,reboot and try connet to pc agian. (warning: make sure backup you phone fist)
Hope this will helping you xD
by the way.. i did tried to root my phone.. but end up failed.. so i cant do stuff like flashing.. those rooting step for is was too hard for me to understood..
To fix this problem (Your Windows 7 PC Not recognizing your Galaxy S2)
1: Try another USB Cable (my original cable doesn't work, a generic one I had does)
2: My Computer Properties - Device Manager - Uninstall EVERYTHING from the Universal Serial Bus controllers list, then restart. - This fixed the issue for me, my external keyboard and mouse stopped working but I'm using a laptop and once I restarted everything works fine
3: Update your phone's baseband radio (I was on XXKI1 and my PC would only recognize my phone when I was using VillainROM, nothing else, until I updated the radio to XXKI4).

tried too but isn't really working..
What root method did you try?
I think you can try by type
*#9090# and select "via UART"
then type
*#7284# and select "UART MODEM" and "USB PDA"
Connect your USB cable and it will auto download the new driver to your computer.
p/s: Need internet connection
sorry all.. finally fix the usb thingy.. i think the problem started with the update i download from samsung.. after i download the DZKJ2 firmware.. my pc unable to detect my phone.. now i switched back to DZKJ1 firmware and now its fixed.. though some function may lost but better than nothing.. thanks for your answer too

Do a factory reset through privacy option in settings.It will solve usb detection issues completely.I suffered same problem and solved by factory reset. Hope this helps those with similar experiences

[Q] Help needed with USB Mass Storage problem

Morning all.
As of yesterday, my S2 won't connect to any pc in mass storage mode.
At first it connected as it should, but after about 5 minutes - before I'd transferred anything - I got a message that windows couldn't recognise the device/driver installation unsuccessful.
Since then I get this message immediately, have tried 4 different pcs.
Would seem the USB drivers are FUBAR somehow, but MTP via Kies works, as does Odin.
I've tried a full factory reset/reinstall, previous backups - stock and custom - removed, reinstalled and updated Kies, cleaned the USB port on the phone - nothing doing. Have tried stock kernels, Siyah, Nimphetamine - nothing. Currently on XWKL1, custom ROM (krinyo's SlimROM) with Siyah 2.6.3+
Also tried uninstalling various USB ports on my home pc, but stopped when I discovered it was the same on all pcs.
It's not the end of the world - I have bluetooth and my microSD - but it's a PITA and I'm out of ideas.
Many thanks for any help/suggestions.

Tried changing the usb cable?
From another post
Dear All
Following are my observations and possible steps to
1. When the phone is upgraded to Android 2.3.4 and above (mine is 2.3.6) Kies stops recognizing the phones and USB connection / Serial port connections etc get reset on the phone
2. Even if proper drivers are there on the laptop (mine is Windows 7 64bit) they are not recognized
3. Device Manager shows "unknown device"
4. Updating the driver also does not result in any help
5. solution lies in the phone
a. key in the dialer *#7284#
b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect (thanks to napi1 @ androidforums.com/samsung-galaxy-s2-international/447145-sgs2-kies-not-syncing-os-2-3-5-a.html#post3484588)
6. The Laptop will start recognizing the required drivers and install them

Getting a Service Mode FC when I enter that code in the keypad.
Will try it with an older backup.
Edit - tried it with a backup of CheckROM , 2.3.6. No FC, PDA already selected. Tried 5c above, still no good - unknown device on pc..

Bugger me, it was the cable....
Bought a new S2 yesterday - nice to have a backup, and the Nexus is meh - and tried the new cable on old S2, everything fine. Old cable on new S2, no good for USB but fine for Kies and Odin as mentioned before.
No idea why it should be like this, but sh*t happens. Easiest solution is often the best!
same problem happened to me too
I have the exact same problem, tried everything like OP, even new cable still same issue...any ideas?

[Q] Windows 7 doesn't recognize my I9300.

So, I cannot connect my phone to any pc.
Problem started after re-installing Windows 7 I believe.
The phone charges fine over usb.
Here's what I have tried so far:
I have changed mtp to ptp.
I have tried using different usb cables and ports
I have re-installed windows 3 times
I have installed Samsung drivers and kies, and tried fixing the error thru kies.
I have tried different kernels (Siyah and stock cm10 kernel)
I have tried on a different pc.
I have tried the stock sgs3 rom, it has Siyah kernel.
I have tried turning USB debugging on and off.
Galaxy S3 toolkit doesn't recognize my phone.
Any help is appreciated.

You say you already tried stock rom with Siyah Kernal. How did you get back to stock did you flash or use Odin?
I would make a backup, Use Superwipe script and use Odin to load Stock Ics 4.0.4 and then try. If that fails you can always restore back to your backup and someone else maybe able to provide a solution.
TBH it doesn't sound like its your PC if you have tried it on other PCs.

I had an older backup with the stock rom in it.
I'm not sure can Odin connect to my phone, so I would end up bricking it completely..

Odin is relatively safe but I am not going to guarentee anything, There is a lot of tutorials on using odin on here and youtube. It is completely up to you what you do. My suggestion was purely based on what I would do in your situtation.

I just tried to flash cf-root using odin and windows just gave me a error.
Could doing a megawipe or a superwipe make windows recognize my phone again then?
Uninstall Kies completely from your PC when its uninstalled reboot your PC then make sure the Kies folder located here is deleted
Program Files / Samsung / Kies
Next download and install Kies from the Samsung web site, reboot your PC once rebooted plug your phone in to the USB (preferably with the original USB cable), let the drivers install themselves.
Once installed you should have it working again.

Done, it says USB device not recognized.
I'm currently installing Kies on a laptop, if it works it means that my motherboard is broken or something, if it doesn't it means my phones usb port is broken.
E: Okay, this windows is saying that the device is in error mode or something like that...

Pants. I'm in the same situation, but my phone isn't rooted. So I can't use mobile odin. Anyone else have any thoughts on this? Is there any way of using stock recovery to either flash an official image or perhaps root?

[Q] S3 Stuck on samsung logo after attempted update to 4.3

I have an unrooted Samsung S3, i just received yesterday the notification of the jelly bean 4.3 update (originally ran on 4.1.2) so i went for it OTA via wifi, long story short, after download was finished and the phone automatically rebooted itself, it got stuck on samsung logo, i have waited for hours beside it (since i have modest experience about this) and finally nothing happened, so i started researching the issue, i have tried wipe data/factory resetting (didn't work) along with wipe cache partition, and no use, i have tried kies emergency firmware upgrade and initialization, but it can't see the phone in Download mode, i tried flashing the phone with Odin307 but it also cannot see my phone in Download mode, and i have heard that if the phones usb debugging was active, the phone would be seen, but i never used it, my phone was stock all the way, please help me get my phone working again.
Make sure kies is completely shut down and retry. You could also try reinstalling driver's and Odin and different USB lead or different PC/laptop
please check in device manager if you can see your device , try reinstalling the device drivers, try different cable or it could be charging port .. Good luck ..

actually i have done all of that, i ran odin while kies was completely shut down (killed all kies from task manager) and downloaded latest drivers from samsung and installed them, tried 3 different wires on 2 different PCS, still my phone cannot be seen inside odin or kies
that is why i'm frustrated
is it possible to use the option "apply update from external storage" from system recovery menu? since my phone cannot be seen by any software, and if possible to use that option, what are the files that i should add to my MicroSD Card? and from where should i download them?
In download mode is the product name blank?

before the update, the charging port worked just fine, the phone was recognized in windows in device manager, and inside KIES, now both of them can't see it, so how could it be faulty?

no its not, showing GT-I9300
In that case try a different pc, lead, version of odin. Either your problem is with the pc (most common) or your bootloader is corrupt, which is very unusual and difficult to fix.

Try ODIN v1.85. It always worked fine for me, other versions don't.
Here is a compatibility list for what is worth it.

Thank you so much for your suggestions, but actually none of the above, i have done the fix that i was asking about (recovering from external card), its a twisted fix but it worked for eventually, i have added the Android 4.3 file (1.43 GB) to my Micro SD Card, and started recovery mode, and went for that option, the device started reading it, and then restarted itself but still stuck on samsung logo, but what i have noticed is that this time when i hooked up my phone to pc, the sweet sound of discovering my phone played, so i know that now i could use odin or even kies, so i went for odin, it recognized the phone, flashed it with the version i downloaded, and it worked. what a relieve

[Q] Root when phone is not detected

Hello everyone, I could not find a good title for my issue but I will try to explain as well as I can. I own a GT-I9300 (International), but since last official Samsung's firmware update(Jelly Bean 4.3) I am not able to get my phone recognized by my computer. Phone is connected and it charges, but neither Windows or Ubuntu recognizes it as a portable device. I am concerned about UMS is not available on device, but my phone it does not even get detected! I also own a Galaxy SII (4.1.2) and it does get detected by my PC. I think that flashing a custom ROM could solve the problem, since it appeared when I updated official firmware, but the thing is that I cannot root my phone! Tried ODIN but since my phone does not get detected, ODIN does not do its job. I also tried rooting with framaroot and towelroot, but no success: first one says "Failed , try another exploit" but there is only one. And the last one says my phone is not currently supported, even if I change modstrings.
So here is my question: how do I root my phone? I don't know what else I could try. I have already reinstalled Kies and Samsung USB drivers but still not working. Also hard-resetted but no luck.
Hope you guys can help me out because this is really getting on my nerves
Thanks in advance!

The thing is that my phone is the only one that do not get detected every single time I connect it. I have already connected one GT-I9100 and GT-S6790L and both get detected. I already tried on 3 different Virtual Machines with Windows XP, Ubuntu, Windows 8.1 but no luck.
As I said in the first post, I think it's a firmware problem since it appeared when I did the official update, which was this one:
Model GT-I9300
Model name GALAXY S III
Country Argentina
Version Android 4.3
Build date Wed, 05 Nov 2014 20:33:08 +0000
PDA I9300UBUGNK1

I can see your frustration Now a few things technically it is a misconception that you need root to flash a custom rom you can actually flash a custom recovery with Odin full wipe and then flash a custom rom from custom recovery (only thing is you will lose all your data because you need root to back up your data)
Now I know the above statement is not very helpful because as you said Odin doesn't detect it (but I thought I would mention it anyway )
The reason framaroot and towelroot, didn't work is because at the moment the only way to root S3 is with Odin.:crying:
You may have tried this but I will mention it anyway first uninstal Kies and all Samsung drivers from your computer ( kies can interfere with Odin) Then try installing these drivers here >> http://developer.samsung.com/techni...Lhp1GqlWRy92Q60CX6PP1mF!80806326?v=T000000117 << If you have tried this then sorry.
Also when you connect the phone go to Device manager in Windows and try to look for your device ( it may say unkown device) it should have a warning triangle right click on it select update driver software and then select browse from my computer and point to the drivers that you have downloaded see if that works.
Another thing to note is if you are using Windows 8 you need to disable Driver signature in start up options ( Google it) for Windows to recognize the drivers.

Also when you connect the phone go to Device manager in Windows and try to look for your device ( it may say unkown device) it should have a warning triangle right click on it select update driver software and then select browse from my computer and point to the drivers that you have downloaded see if that works.
Another thing to note is if you are using Windows 8 you need to disable Driver signature in start up options ( Google it) for Windows to recognize the drivers.

I already tried uninstalling Kies and Samsung drivers. Also I tried looking for device on Device Manager but it does not appear when I plugin my S3, but it does appear when I connect other devices like S2 or Galaxy Fame Lite. They appear as portable devices.
I'm using Windows 7 on my PC and have already tried with different OS over Virtual Machines and still doesn't work.
And thanks for that note, didn't know there was possible to flash a Custom Recovery without root, but I can't since ODIN doesn't detect device :crying:
Then it looks like you are running out of options I would use another computer not Virtual Machines
Okay I'll give it a try but as I said before, looks like an firmware issue, not computer's. Why would my computer detects two another Samsung devices but not mine (which used to work until last update)
Me, too!
I'm having a similar problem. Last week my GS3 stopped working, and I bought another one from Ebay with a cracked screen and swapped out motherboards. The phone seems to work as well as a stock Verizon phone on Jellybean would, but I can't get my Linux, Win 8, or Win XP computers to even recognize that it's attached. Different cables, each and every one of the USB ports, not even a blip. Device Manager in Windows doesn't even see it, and yes I got the developer options unlocked and have enabled USB debugging.
I've got the Samsung drivers installed, and tried to install the CWM device drivers from the SAMSUNG GALAXY S3 TOOLKIT V9, but there was an error and that didn't work, either.
USB connection issues are usually due to Windows conflicts, driver problems or the lead itself. If all these have been excluded then you have either a firmware issue in the bootloader, which is very uncommon, or a hardware problem. The usb port is easily worn/damaged/dirty also the motherboard might be the cause.
There is no silver bullet to cure, test each possible thoroughly.

I'm 100 percent sure that it is not due a Windows issue, I have already test every option. I have not considered the usb port to be damaged or worn, which could be possible but phone charges every time I connect it to computer. It just does not get detected as a device. But in order to assume it is a motherboard issue I will have to put away my feeling that the problem is caused by last OTA official update, since this problem started there.
If it is a firmware update issue, is it any option to flash another ROM?

As I said on previous posts, I have already installed and reinstalled Samsung USB drivers and made a factory reset -one from config. option and another one from Android stock recovery 3e (since I cannot install any advanced recovery -or even root it- to flash a custom rom). Doing those factory reset did not downgrade my last firmware update (when all my problems started).
I also said on previous posts that I tried towelroot and framaroot with no success. As tallman43 says, seems like international version of S3 does not support those kind of one-click to root apps.
-----------------------------------------------------
So far the only options available (if my theory about latest firmware update is the problematic one) are:
● downgrade firmware: [Q] How? Odin is not working since my phone does not get detected;
● root my phone in order to install an advanced recovery and flash a new ROM: [Q] Any way of rooting phone without computer (apart from towelroot or framaroot because I have tried and do not work for me)? I read one XDA post from 2 years ago to root S3 via console apk but latest comments assumes that method stopped working.
● install an advanced recovery without odin or root: [Q] How?
● fix USB firmware issue: [Q] I have completely no idea how to do it. (Already played with *#7284# and *#0808# but did not get my phone detected)
Please I need help, this is really irritating me and I am running out of ideas

I guess I have found out what the problem was. It was not firmware (as I thought). It was the micro USB port (as boomboomer said) which seems to not be firmly attached to the PCB. AC charging just seems to work okay, but not USB connections. I managed to figure it out by forcing the USB in a specific position to get it detected for 5 seconds, but then it disappeared.
Yeah, it was not as complex as I thought! I will try to replace that micro USB port as soon as possible, thanks everyone for your help!
