[Q] conecting via USB - Galaxy S II Q&A, Help & Troubleshooting

Hi, I need advice, today I made the root SGS2 and when you want to load custom ROM so I need to get to the phone memory. But since I can not root galaxy connect to it via usb to pc not know what to do? I tried to reinstall the drivers remove kies etc.. nothing ..
Thank you all for your advice.

What?

Aha ..
Sorry for my bad English.
so, again
Today I made a root on my Samsung galaxy s2.
Since then we can not connect the phone to the computer via usb cable.
Because I want to insert a custom ROM, you need to connect to the PC.
Therefore I would like to ask you whether you know what happened? Why can not I connect to PC via USB cable while before we root via usb cable worked.
I tried reinstalling drivers but still nothing.

Don't know about the whole pc-thing, but you can download roms directly to your phone.
And btw, opening two of the same topics is not the way to let people answer your questions faster. Next time just open one thread.

......and you can flash them in .zip form with cwm,or .tar form with mobile odin.So no need for pc or to talk crap.

Yes I know, but I need to download a backup from mobile to PC

Well if you want to go into usb mode...settings> (under wireless) go into more settings>usb utilities>connect to pc
Then connect your phone to the computer and remember to keep usb debugging off..
Or you can simply take your data in a mmc via card reader and put it into your internal from the mmc...
Press thanx if I helped...

USB of LG O1 not getting Detected by PC

First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use
Before going to any service, do a backup and Factory Reset your device, then try again...
I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

Try another cable.

None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.

Installing official ICS without a usb cable?

Hi folks.
Can anyone tell me how I can do this? I have a usb cable but my device suffers from the usb port problems which have been common on this phone. I can charge my phone ok but it won't connect to my pc as an external hard drive, through Kies or Odin.
Can anyone help. My sgs2 is rooted and running checkrom v6

Search for "mobile odin" on XDA. It's what you are looking for...
Try mobile Odin (paid app). Put your firmware files on SD card and flash via mobile Odin.

Dropbox
1. Put the rom on dropbox
2. Download app dropbox on mobile
3. Turn wifi on
4. Download rom onto sd card in your chosen folder
5. Reboot into recovery
6. Flash the rom
No usb cable needed there are other methods also but this is probably the best way i do it.

Root without a PC?

Hey guys.
My girlfriends Galaxy S 2 won't even recognize it's plugged into my laptop, yet it will charge.
Now it's no deal at all as she never plugs it into a PC anyway, I just transfer stuff bluetooth.
But I want to put a custom ROM on it to get rid of all the carrier bull****, but being un-able to connect to a PC, how can I root it and install one using just the handset itself?
Please help me?

Not possible imho without pc, uninstall and reinstall Kies or the usb drivers for connection. Disable usb debugging.
Oh ok, bugger. And I've tried doing that, doesn't seem to work.
The phone doesn't even come up that it's plugged in. Nothing.
search in the development section
there was a method to root ics without flashing anything from pc
I have but can't find anything.

Is the S2 already running ICS firmware? If so you can easily root using the method here: http://forum.xda-developers.com/showthread.php?t=1501719
Just put the two linked files on your internal sd (either transfer then via bluetooth or directly download from your phone through the browser) and follow the instructions, literally a 2 minute job.
Yeah seen that, but it's not ICS

Nope no go, just did that. KIES just says please connect a device
My galaxy Nexus connects up fine, just not her Galaxy S 2 yet it will charge fine. Dunno why.
EDIT: I take that back, left it plugged in and now it's making weird noises and sayings installing device driver software.
Sorry somebody else had posted my way of doing it
Just to eliminate another option have you tried cleaning the USB port on the phone, I have seen quite a few posts here and there saying that it has helped
dj_sploits said:
If you are on a stock ICS ROM then you could always get the files for CF-Root. You pop them on your SD card and then you root your device from the phone itself. After that you could send the custom roms over to the SD card and install them that way? No PC needed
I'm sure this way works but if not hopefully somebody will correct me

Not possible, you have no cwm to flash it with, sammy`s 3rd recovery doesn`t allow flashing custom software. You need to have cwm.
---------- Post added at 09:17 AM ---------- Previous post was at 09:16 AM ----------
You could try another usb port
Now WTF.
I rooted it, used Rom Manager to flash CWM and it's still the stock one.
Why isn't my phone this ***** hard.

Why are u using rom manager, it causes problems with sammy based roms. Turn off the phone, press volume up + menu +power buttom at the same time, you should get in cwm. Don`t use rom manager!
Did you try to connect on another pc? Or at least on another usb port? Windows should at least recognise that a new hardware has been plugged in

Phone not detected by windows 7 help!

Hi guys,
I'm new to this forum. I've got a Samsung i777 on android 2.3.6 kernel 2.6.35.7 build number gingerbread.uckk6
I've recently bought this phone off ebay
My phone does not get detected by windows 7 or Macbook. I've tried changing the USB flex cable with I9100 v2.3 but still no luck.
When I connect USB port it beeps and shows mtp-initialization/mtp-connected on the phone but it is not shown on windows. It says USB cannot recognise the device. I've got a s3 and ideos x3 both of them are detected.
I've installed kies 3 on my laptop.
I had to swtich off the wifi on the phone because it consumes a lot of battery, I think it is because of the android version I'm using!
I want to root the phone and unlock it!!
Any help is appreciated!

I'm guessing the problem is the Samsung drivers you have installed for the s3. Try uninstalling those and installing the correct drivers for s2.

you can check this thread for driver
http://forum.xda-developers.com/showthread.php?t=961956
You most likely need a new cable. Happened to me once! Could be the drivers but I HIGHLY recommend just trying a new USB cable.
Thank you guys for all your help really appreciate it!
I have tried all the steps mentioned above tried to uninstall all the previous drivers I had and installed the new driver as mentioned in the above link but no luck
I tried it on a friends computer with a different cable still it shows the USB device is not recognised!!

Did you install another ROM? It might help to Wipe system, Data, ETC! it appears to be a software problem. Or at least my guess is the ROM your using.
The Galaxy phones all use the same USB drivers whether it's an S2, S3, S4, etc., so if the installed drivers were working for your S3, it's unlikely to be a driver issue.
Can you boot it into download mode? If you happen to have a USB jig, that's the easiest. Otherwise, power off the phone, unplug the USB cable, hold Vol +/Vol-, then plug in the USB cable. It should go into ODIN download mode. See if Windows detects the phone that way. If so, it very well could be something weird with the OS installed (although it appears to be stock).
If you can get into download mode, you can flash a stock kernel to make sure you are starting fresh. A good file repository is found here. I recommend the stock UCKH7 image I777_UCKH7_OCD_No_BL.7z (you'll also get root).
And yes, the UCKK6 release had a serious bug related to the wifi that could drain your battery. Best to go with UCKH7.
You could also download an app that allows you to enter download mode.

I was able to boot to download mode by holding the vol +/- key and then plugging in the USB cable but there is no movement from the computer it doesn't make a sound nor does it detect. I tried restarting the phone then I get a notification on windows that USB device not recognised!
Yes I guess this rom is useless, if the wifi is switched on then battery would not even last 6 hrs!

Are you saying to get a balloon notification in the tray that says the USB device is not recognized? A possible reason for that is a faulty USB cable or USB port (funny enough, I actually got that message last night when I was playing around with my Captivate, and switching USB ports made it work). I know you said you've tried other computers an another USB cable, but that's about my only idea. Maybe there's some debris inside the connector that's messing up the connection.
When you say you changed the "USB flex cable", are you talking about the internal connector and board inside the phone? If so, perhaps the I777 connector board is actually a little different than the I9100 board and causing a compatibility issue.
The bug in UCKK6 related to wifi didn't affect everybody, but it definitely affected a lot of people (based upon reports here).

If you have an SD card, you can download another ROM on that SD card from your computer and then you can install custom recovery (CWM) and then install the ROM from SD card.

First ill run you through the problem I had. Just for reference did you use Mr. Cooks script before flashing Cyanogenmod 11? One of his scripts for cleaning before flashing, actually deletes a certain file, not to keen on which one. What it results in though is not being able to flash OF ROMS and some certain custom ROMS! So id recommend alliance's ROM! As for the "Getting the ROM on your device, you could put the ROM on your SD though recovery "Mount and storage/Mount mass storage/" or just use a micro sd card adapter and move it on there that way.
Thanks for your reply. Would you mind sending me the link on how to do that step by step as mentioned I'm new to Samsung phones and also this forum.

What state is your phone currently in? Is it still not detected by the computer? You are still on 2.3.6, correct?
If it's still not being detected by your computer, I'm not sure if you can flash anything needed using the stock recovery. I know that when I flashed stock JB, I was able to boot into stock recovery and directly apply the standard CWM update file here. It will give boot into a temporary CWM that should allow you to flash other ZIP files (like a ROM), although I had trouble doing that (so I ended up flashing the AJK_v4.9_NoSwap.zip kernel using the MobileOdin android app, which gave a permanent CWM recovery).
I'm not sure if this same process works with the 2.3.6 recovery. However, in order to get the stock recovery to see the internal SD card, I had to run adb shell commands to mount the partition (meaning I had to have a working connection from the computer).
Solved!!!
HI Guys,
Many many thanks for all your responses!
I have changed the USB flex cable again to an older version v2.2 and my phone is currently being detected by kies! So relieved thanks a lot for all your help..now the rooting begins!!:laugh:
