[Q] [HELP!] Phone stuck on Galaxy S II screen

Like the title states I'm stuck on the splash screen. What makes my problem a little tricky is that I can not access recovery and I can not use odin, because the samsung drivers are not installed and will not install until I plug in a booted samsung phone into my computer to prompt the driver install. So, unless there is a way to install the drivers without plugging in the phone or another way to flash cwm (which i lost on a bad rom flash) I am really screwed. Please any help I can get would be greatly appreciated!!

update: Sprint ended up just giving me a new phone at no charge! problem solved I guess. thanks for everyone's help
Navigate to where you have the drivers on comp. Open the file and look for the one ending in .exe click it and install manually. That should let your comp see your phone.

If you don't have the driver package search Samsung kies download drivers and use above instructions.
Heres a link for the drivers.

G3 Hard bricked, need help

So, I am a victim of the McAfee killswitch. I rooted my phone, then unlocked bootloader, but I made a mistake and had to flash kdz. For some reason, the kdz i downloaded was locked in mcaffee, so i really struggled but managed to install twrp, and of course root. The phone worked fine for a long time, but then I messed up and got a bootloop. The thing is, my killswitch is engaged now, so I can't just go into TWRP and wipe, or go into download mode. Both locked. And if i try to boot normally I just get the loop... So my questions are: Is there a way to get into TWRP directly (without having to confirm, phone could reboot to recovery just fine). Or just flash kdz, i don't know, anything. ADB shows device offline and sometimes unathorized, fastboot doesn't detect it. LG service said it will only fixed if i replace everything. Any help?
Sounds like you need togoba I to stock using lg flash tool

Try using the kHz method if your computer will reconize your phone. Use LG flashtool 2014 it will put your phone in download mode for you

Kdz
How will it put my phone into download mode? If i click start, it says the phone is not connected to the computer. My computer can see the device as ADB device, but only offline or unauthorized.
When I used it my phone was stuck on the LG screen. Flashtool found my device and started the upgrade then it booted my phone into download mode
That does not work for me.. The program is stuck at 60% and telling me phone is not connected.
The only other option I can think of would be to a hard factory reset. Make sure your phone is off then hold down power and volume down together when the LG logo appears keep holding them. It should take you to that menu
I already said I can't go into recovery like that, because there is a killswitch activated on my phone.

I guess it will be very hard to flash KDZ or TOT cause you need to put your phone to download mode or need to connect ADB. following the post.

Lg G3 D855: Hard Bricked After Trying To Flash

Lg G3 D855 hard brick need help
Hi guys my phone has bricked so i tried to do the tot method and is almost worked but i saw on the screen that blue background and a white text "Reset factory status" something like that...
and the number "2" in a big so i checked what the hell is that number 2 means and it means that is not good becouse to finish the hard reset i need to see the same blue backgroud but with the number "3" thats means that every thing is ok .
so after that i tried to flash it again on Lg Flash Tool and it take 14 seconds to tell me that "Cant Change To Download Mode 00000064" and every thing is ok my phone did changed to the download mode but on the program it says that it cant change to download mode ?:
some one can help me please i will appriciate that !
Q. When I tried to follow the above method I get a "Can't change to download mode" error referencing "Error 00000064"
A. I experienced this several times when attempting to un-root using a USB 3.0 port. Connect the phone using a USB 2.0 port preferably connected directly to the computer - and make sure the phone is already in download mode. Occasional you may need to unplug the USB cable from your phone for a couple of seconds and reconnect to get the process started.

When you're stuck at the factory reset status 2 page, you should go through the entire guide linked before. then at Step 7, instead of having the LG FlashTool set to 'Upgrade DL', you should change it to 'Board DL'.
You'll see an AAT screen(you will know what this is when you see it) on your LG G3. Click OK here, even though it says not to, then you press and hold the power button so you can reboot normally

Bootloop on download mode.

Hello everyone,
I've tried to flash a rom using odin on my J610G and it failed. Now while trying to get into download mode the device restarts automatically. It's recognized by the computer but it won't stay on download mode. It won't boot into the OS since it prompts "An error has ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I tried the smart switch but it won't stay on it, It keeps restarting. Any suggestion ?
I have the exact same problem too! It's so frustrating coz I just can't get my phone to stay on Odin mode without it restarting to that stupid error screen:crying:
Simple. Charge your battery with the mains charger, its flat.
Did you find a fix?
---------- Post added at 06:16 PM ---------- Previous post was at 05:39 PM ----------
I ****ed my mom's fone and its constantky restarts ; I can reach download mode but only for an instant. recovery isnt there at all. Please reply how you fixed it please I beg you. I want download mode to stay for some time so that i can boot new frimware but that isnt the case. I am crying man please help.

I got the same problem. I had to extract the battery and charged it with a external battery charger, because if I tried to connect the phone with the normal usbC cable, the continued with the boot loop y download mode.
did you find a solution sir?

I recently tried to install a custom ROM in my samsung j6+ but halfway through it my PC turned off.
Then the problem starts i decided to reboot my phone but it shows this error "No command" " #Reboot recovery cause is [[check_bootmode]RebootRecoveryWithKey]#
Block-based OTA
Supported API: 3
# MANUAL MODE v1.0.0#
E:Failed to mount / cache: Invalid argument
The error message keeps appearing for just a fraction of a second then disappear and appear again
I tried to go to recovery mode but no luck i cant get to it
I drained the battery to turn off the device then go download mode but after get to it, it also keep restarting
help me please. thank you
I am having the same problem, is there a solution other than "Charge your Phone"?

Is there any way to unbrick my phone?

I was trying to flash Android 10 on my LG G7 Thin Q (LG-G710PM) with the LGUP cmd method, but I must have flashed an incompatible KDZ file or something because the process bricked my phone.
It won't boot no matter what I do, though my PC does recognize the device still (It recognizes it under other devices as QUSB_BULK_CID:0402_SN:333F0715)
I don't know what to do, and it would be a big shame if I truly just ended up killing my phone.
Update: I've downloaded Qualcom USB Drivers onto my computer and now the device is being recognized as Qualcomm HS-USB QDLoader 9008
