[Q] WHO's FEELING GENEROUS (ODIN,KIES ISSUES etc)

Hey gang, needing some help in regards to Odin and Kies.
Apologies if this has been answered but ive been all over the net trying to find a soloution and as Princess Leia says, "youre my only hope".
Ok the main issue im facing is ODIN doesnt recognise my phone when connected.
The installed software i have is as follows:
Android version: 2.3.5
Baseband version: I9100XXKI3
Kernel version: 2.6.35.7-I9100XXKI3-CL577579 [email protected]
Build Number: Gingerbread.XXKI3
Now i can put my unit into download mode but ODIN doesnt pick up on it.
I also have a connection issue with Kies not seeing my phone either, although when i connect my unit to my pc (alienware m11xr2) it gives me the option to connect as USB storage..?
What im wondering now is there any soloution to this?
Can i root from the unit directly as i cant get ODIN to see my unit?
Thankyou in advance for any help given to both issues
Uninstall/reinstall Kies on your PC (with a reboot of the PC after each step). Try different USB cables, try different USB ports. When you're using Odin, check Task Manager in Windoze & make sure Kies isn't running/kill it if it is running (Odin & Kies don't play well together tho you need Kies drivers to use Odin).
Try a different PC/different OS if all else fails.
You can't root directly from the phone as far as I'm aware. If you're using Odin 3 v1.85, try Odin 3 v1.3.

Make sure USB debugging is checked under settings. If Odin worked before on your computer, try a different one. Install proper drivers and reconnect your phone to the different computer.
Are you using Windows 7? If yes then you should try installing Samsung Drivers in compatibility mode for Win XP and then go to device manager in PC and under USB Serial Controller dropdown, you'll see "USB Composite Device"(maybe 2)..Just update its driver, after update it should show "Samsung USB composite device".
Do it with phone connected to PC and USB debugging UNCHECKED. I'll post screenshots when i go home.
You can use mobile odin to flash and root. Use Kies Air to get the file onto the phone.
Edit: Disregard you need to be rooted to use the app.

thanks mistah bungle, ill have a go now and ill let you know how i get on
OK, tried all mentioned steps Mistah Bungle and no joy.
Uninstalled Kies,rebooted no change.
Rebooted tied Odin both 1.5 and 1.3 no change.
Rebooted tried all USB ports no change.
When plugging in the USB cables though and watching the laptop install the drivers i noticed that the 1st step was ticked and the 2nd (USB Driver) crossed, this occured on all USB ports on my laptop.
I managed to download the SAMSUNG USB Mobile Driver onto my laptop but still nothing changed.
Also have tried ODIN with USB debugging on and off just to be sure but still no change.
Just for your knowledge, my laptops running win7 64bit, 8GB RAM,icore 7 etc
Just seems strange how ODIN used to work before when flashing my device and suddenly this stops..?
lol thanks...well almost
looking forward to seeing if this helps, awaiting yr screen shots etc
Another PC looks like the only way you're going to get it done in that case. Yes it's strange, as to why, that's anyone's guess.
i am also running windows 7 64 bit and odin works great for me. One thing you can try is see if the phone is being detected under USB in Device manager and if you see it there right click on it and click uninstall and then right click and select scan for hardware changes and it should pick up the drives again. Also try disabling UAC(user account control) reboot then try. Let me know if it works.
...
ok went to Device manager as in picture 1 and deleted Samsung Mobile USB modem, unknown device and GT-I9100.
Then plugged phone back into USB and have now, as in picture 2
Thanks in advance people
Are you following the basics ,
Use the USB cable that came with the phone and only connect to a USB mainboard port .

begining to think maybe the issue is a physical one as when i try to set USB debugging mode the handset is telling that the USB cable is connected!!!

OK god knows how i manged it but managed to get USB Debugging selected,used zerg exploit to gain root access to my phone (confirmed this using ROOT Check Basic from Android Market)
Now all i have to do is install clockwork mod again
????
Tried Clockwork aborts...
What does work right now?? U can boot phone? Access cwm but it reboots?
I had the same issue but very simple to resolve. First thing don't use usb netconnect at the same time when using phone data cable and if u r using front side slots for usb they may conflict with other usb devices drivers ...most commonly with usb netconnect... So use back side slots when phone is in normal mode..... Re- installing and unistalling will not resolve this... And be patience..... Be sure drivers are installed and if installed then no need to uninstalling and reinstalling... 100% it will work

Ok i can boot the unit on and have clockwork mod installed, i have checked that the unit has root access.
I put the unit into recovery with clockwork mod, this is what i get:
--Installing package...
Finding update package...
Opening update package...
Verifying update package...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted
so i have to reboot.
Powers up showing no yellow triangle (yet when in download mode says 3rd custom binary and below samsung official).
powers on,seems to be ok then the voice talk app opens, i try and close and this goes on for minutes,on off,on off, i turn the phones screen off,it comes back on
This unit is very unstable at the moment for example:
The unit again is now not recognised by the USB ports allowing me to mke it seen as an external memory device from unit. ,its deffantly the unit,now that i managed to get root access i was going to transfer odin mobile accross from my pc and lightning 6.1 tar, then hopefully reboot,install odin flash lightning and viola problem solved....no such luck.
Voice talk is activating itself now continuesly opening as stated and putting the phone into car mode,just when i think i have 1 problem solved its giving me some thing else to contend with.
i admit im not the most technical at this and need step by step instructions but ive flashed over 50 ROMs/updates on this unit with no issues what so ever, maybe ive just pushed the poor lil bastard too hard for too long (since the day i got it, its been flashed) and possibly its getting revenge because it knows its just a matter of time until i get the SG3...?
I have the will and the patience to want to win this battle im having as i love the phone, but maybe the day is coming where phone meets wall,lol?
anybody?
OK managed to bluetooth ODIN mobile and lightning 6.1 tar onto the unit, hopefully have just flashed the phone....fingers crossed...
Well thats killed it, now unit is stuck on Samsung Galaxy s2 screen and wont boot up.
Can get to download mode but still not recognised by ODIN.
Vol Up, Power On, Home key gets me to clockwork Mod 4.0.0.2, go to install zip from sd card and wont select choose zip from sd card.
On screen says:
ClockworkMod Recovery v4.0.0.2
E: Cant mount /cache/recovery/command

Big problem

Hi people, i got very big problem and i hope you can help me to solve it.
I got Samsung GT-I9100G with android 4.1.2, kernel version 3.0.31-893450
And i got problem with usb and recovery. First problem is with usb. When i connect my phone to my computer, it shows that phone is charging, but no conectivity, my computer shows message "Device is not recognized. I tried every single solution i found on google but it didnt helped me. I got his original usb, i tried many different usb cables and different computers but it didnt helped. My phone is rooted and usb worked earlier perfectly. Im using windows 8.1 on my computer, i tried many different drivers for my phone, didnt helped me either, tried with factory reset, still nothing.
My next problem is with recovery, i tried to flash another system, but i couldnt. My phone got his default, original recovery. It shows me problem something likv "failed verification package, or something like that. I tried to flash another recovery, it shows me the same thing. Now im wondering is there any fix for these two problem, or atleast with the second one, so i can flash new android version.
Thanks in advance, and sorry for my very bad english.
Cheers!
Flashing blazinh kernal v16 should solve the issue..
Thank you very much. This solved my problem!

[Q] GT-I9100G recognized as modem in Download mode

Hello guys,

I tried much stuff untill i flashed a stock kernel via cwm (B_Safe_Kernel_XXLSR_CWM6). Now my cm 7 is broken and im not able to reflash it via CWM.
I just need helt to get that modem driver recognition to work.
can anyone help me? if you need some more informations just aks me and i try to get them!
greetings alex
**1. Edit**
So the cwm error was status 7 and easy to fix. i installed cm 10 now and ill try to fix the problem with the drivers in download mode

Samsung Galaxy Ace GT-S5830: Unknown USB Device (Device Failed Enumeration)

Hello, I am sorry if this post has already been made somewhere but I still can't find the answer for fixing the problem suggested in the title.
So I have a GT-S5830 Galaxy Ace and decided to install CyanogenMod 7 with CWM. The flashing of the phone was a success but I came across a bug (or problem?) of screen orienteering and I couldn't find that answer. Right after this, I then decide to restore back to stock ROM. However, I came across a problem when connecting the device (in Download Mode) to my PC; it stated Unknown USB Device (Device Failed Enumeration) in Device Manager.
Following Procedures I have done:
- USB Debugging enabled on phone
- Samsung USB Driver installed
- All drivers on PC up-to-date
I am also following a guide to restore back to ROM using Odin Multi Downloader, but it does not recognize the phone in ID:COM. The bleep on the PC can be heard but it only recognizes when the phone is in normal mode; in Download Mode it shows Unknown USB Device (Device Failed Enumeration). Please help as I am giving this phone to my sibling.
Thank you. (I think I may have posted this on the wrong section of the forum, sorry)

I'm having the same error as well. I am running on stock firmware 2.2.1 and unrooted still when I enter Download mode (Power-VolDown-Home) my PC says USB not recognized. I'm trying to play some combinations and I've been into RAMDUMP, Emergency DLOAD mode and ODIN can detect it, but can't flash. When I press Power-VolUp-VolDown it Says LK (lucky kernel) version Jan 2011.
Tried updating via Kies but it says Can't update firmware. Unknown error occured. This is crap! I can't go on to 2.3.6
I have exactly the same issue. :crying:
Does anybody has a solution for this?
please help
same issue here.:crying:

Need help with a truly bricked Galaxy S ii

Hi everyone,
I have an SII GT- I9100 that I installed a custom ROM on a while back (probably 2 years ago). After a while it got badly bricked I don't remember what happened, and not only that
the charging port was also messed up so I couldn't connect it to my pc (pc wouldn't recognize it unless I held the cable in with force, but even that didn't work after some time).
It's been sitting on a shelf for about a year and I decided to buy a new charging port, replace it, unbrick it and give it to my mom.
I did replace it and I can connect it to my pc now but there's still issues. On my main windows 10 pc it gives me an error "USB device not recognized, the last USB device you connected to this computer malfunctioned, and Windows does not recognize it". (I've reinstalled usb drivers and troubleshooted with Kies).
I keep the phone in download mode while I am trying to connect it to my pc since I can't boot into anything (I have a yellow triangle and Samsung logo if I don't go into download mode).
On my laptop (win 7) I've managed to get windows to install all the drivers(even though it failed a couple times ?), I've also troubleshooted with Kies, still Kies can't connect to it.
I want to restore it to stock ROM but I haven't been successful. First Odin gave me "setup connection" error but then I rebooted the pc and it "worked".
Now it just says complete (write) operation failed.
I've tried 3 different Odin versions, nothing.
What bothers me is that Odin says "Added !" but everyone online to the people with similar issue says that they should reinstall drivers or talks about USB Debugging (which I can't turn on or off since it's bricked).
Sorry for the long post but what's the move here? Am I using a bad ROM ? I've tried one for the country I live in but not the country from which the phone is ( I don't know the country, might be Austria), could this be the issue ?
Thanks in advance!
Update, I may have found the right ROM, now it's stuck at boot.bin
EDIT: Found a youtube "solution" to that, then it got stuck at cache.img
EDIT: Getting Driver issues again, Unknown Device :/
