[Q] phone to pc screen :(

dont kno if im posting this in the correct section or not but can some one plz help? i was trying to flash the stock files for my samsung vibrant with odin, but it froze so i unplugged and tried to reboot my phone but the phone to pc screen came up. ive tried holding the volume buttons + power to get back to download mode, but it just reboots and goes back to it, can anybody help?

Did you hold the power button down till it disappears and then release the power button immediately as it disappears?

hadnt tryin releasing the power button right away but i just tried and still no luck

Johnz is right. To make sure, unplug & plug back in the usb cable, then hold down the volume keys & power, wait till the screen flashes to black, then release power.

Unplug and pull the battery.
Install battery.
While holding both volume buttons, plug in usb cable.
Have odin ready to go, it seems to help. The phone should power up directly to download mode, once odin sees it, hit start.

i dont get what im doing wrong because ive tried what u guys said but after the screen flashes black when it comes back on its the phone to pc screen. ive also noticed that if i pull the battery while the usb cord is connected the phone stays on at that screen until i remove the usb cord, is that normal?

i just read that if the normal ways dont work that means ur phone is hardware locked. looks like im gonna have to try to send it back to tmobile and hope for the best

Try the above, but also hold the home key. I did the exact same as you, and this enabled me to get back to download mode, so I could Odin.
1) Remove battery, SIM, and sd card.
2) Plug in USB Cable.
3) Hold down Vol +/- as well as home.
4) Press power button for 2 seconds, then release.
This should get you into download mode. Then you can Odin back to whatever you were intending to do.

thanx for all the help guys but nothing seems to be working for me

Just throwing out an update incase anyone was wondering, I got my replacement phone yesterday and it turned out to be hardware locked as well. Tried to flash the fix for it and it failed and bricked my phone! So after calling tmobile they will be sending me another replacement and hopefully that one wont be locked as well

I had the same problem trying to get into Download Mode, I got into download mode and using ODIN tried to flash update. The process was stick for 10 min.
So I unplugged USB and got this phone to PC icon. All I had to do to fix it was to go into download mode again by holding both vol +/- keys and pressing power button until screen goes black then release the power button as soon as the screen went black. If you hold the button longer it will go into recovery mode. Then open ODIN again and re-connect USB and ODIN will detect COM port. However you have to make sure that all samsung usb drivers are installed. That is it. Then flash the update and you all set. The phone will reboot and you are back up and runing.

there is another way to this method, that works on any vibrant i've tried it on and also the captivates, had to help a friend restore his yesterday.
remove battery, sd and sim cards
plug in usb cable to pc and phone
hold down the volume buttons only
pop in the battery
if it comes up to the battery charging icon, pull the battery and put it back in again, should go right into download mode.
again, this works on any vibrant i've tried it on, and the captivate as well, good luck.

boot loop after trying to flash twrp 2.2.1

Okay so I seem to have run into a little problem I was planning on updating cleanrom up to 1.2.5 but was on cwm. I had managed to switch over successfully to twrp 2.2.0. I went ahead and used goo manager to download the updated zip of 2.2.1 and tried flashing it thru twrp. Now I am stuck in google bootloop and cant get into recovery or more importantly bootloader. I have been trying last 30mins to hold power and both volume buttons but it either keeps rebooting back to the google screen or not doing anything at all just have to repress to to turn it off but it will turn back on automatically. I tried hooking it up to my usb and labtop but it looks like it wont even recognize it. I just fully charged it so I am good for now just a little worried cant get out of this mess.

I ran into a problem like that with clockwork recovery it kept on rebooting in recovery but I could still go into download mode I was at work away from my computer so I had no choice but to keep trying that three button magic until it finally restored a backup I had on my external card.just keep on trying to pull the battery then try to go into recovery. You might 've gotten a bad download

problem is I cant get into recovery. or the green screen to get to bootloader. It just completely stuck in a bootloop on the google screen mocking me... I am really contemplating opening it up and taking out battery but is that a good idea? Or is there anything else I can do?

so I pulled off the back cover but really dont want o disconnect the battery might mess something up but I cannot get the device to shut off.

disconnecting the battery does nothing it shuts it off and keeps it off but when I connect it to the charger the battery symbol pops up for a second and then goes completely blank. I went ahead and tried again to boot into bootloader pressing power vol up + down and all combinations of power vol -, power vol +
power turbo press vol +/- but no luck still in google screen.

If you're in a bootloop you need to connect your Nexus 7 to a computer. Then you will be able to access recovery via the Power button and volume buttons.

is it going to make a difference that everytime i try to reboot it just the black google screen? I have tried it connected to the wall charger and connected usb to the labtop but nothing.

It's supposed to do that when you're trying to go to recovery from bootloader without the USB cable plugged into a computer, may need to have the drivers installed on said computer. It's an issue with the nexus 7 bootloader and every one of them does it. What your experiencing is perfectly normal if you tried to go to recovery from bootloader with the bolume buttons and then got the google screen bootloop.
If it doesn't work when you plug it in and try, then try unplugging it, manually rebooting with it plugged in first, or vice versa
Update: I can get on Team Viewer and remotely reboot you into recovery through the PC if you want, or at least give it my best shot.

ok so i disconnected battery and have the device off. I should then try connecting it to the pc and try booting up holding down all buttons?

Have you installed the right drivers on the computer you're using, for ADB and the device drivers, when you unlocked and rooted?
Answer to your question is yes try that. But I wouldn't be disconnecting and reconnecting it, I can't recommend that and then learn tomorrow that static zapped something important.

yea I am getting nothing by connecting to pc. I have all the drivers adb and fastboot installed when I rooted and unlocked couple weeks back but it looks like device is not being recognized or read at all by the pc.

connecting to the pc holding the volume + button gets it recognized for a second and tries to install a driver apx but unsuccessfully.

I am not making any progress whatsoever kinda sucks starting the weekend like this. I have gone thru some bad stuff with my atrix but nothing like this were I cant even access my bootloader boot into recovery or even fastboot. Should I try and get it to just stay off and see if overnight it works its own magic? Hate going to sleep witht his on my mind but I think with a clear mind in the morning something good will happen.

I can get it to stay off by holding both vol+ and vol- but trying to turn it off with just the power button just keeps it turning back on/off...

so I slepted on it thru the night let the tablet rest but went back this morning and I still cant get into bootloader or recovery. Is there anything I can do?

Has anyone else had this problem where they cant boot into recovery or bootloader? It's like the power button and vol keys are unresponsive even though they still work to turn on the device.

are you sure that you flashed the right recovery? but you should still be able to get the bootloader. are you pressing power + volume down(volume down, not both volume buttons. i noticed you wrote both volume buttons) to get into the bootloader?

I think I chose the right recovery the first version downloaded thru goo manager but it was the 2.2.0 version. I had the option on the of downloading the 2.2.1 zip or the .img but i downloaded the .img to just to flash with the current version of twrp that was working. There have been times were I have not been able to get into recovery on my atrix or htc but I've always been able to get into the bootloader this is the first time I've been locked out of my device kind of got me scared its not even a month old. So you say to get into bootloader you dont have to hold down both volume buttons? I will try again to power back up using the volume down and power button at same time... Wish me luck

good luck!
yea, only power button and the volume down button.

quick question before I connect the battery does it make a difference whether or not I have it plugged in charging or connected to the PC while trying to boot into bootloader?

Brick Scare: Can't Access Recovery From Hardware - Only From Software

So I have this strange issue. I just tried shutting my tablet down so I can reboot to recovery to flash something. (Mind you, I haven't flashed anything in a few days)
So I shutdown and I can't access recovery. It just wont boot. Vol+, Vol- and Power at the same time. I tried going power first, then volume and vice versa but no dice. My volume buttons and power button work perfectly fine while in the ROM.
Now at this point I was like, "Screw it, I'll boot into the ROM" but no.... It wouldn't even turn on. I tried plugging it in and nothing (~70% battery when shutting it off). Then I plugged it into my computer and it showed "Device driver software was not successfully installed" with a device named "QHSUSB_DLOAD".
Quick Google-ing made me think I bricked the device. I ended up just holding on the power button for a good minute and it finally booted into the ROM. I'm still unable to boot into recovery via Power + Volume Buttons... I have to use an app to boot me into it.
Why? What happened / is happening?

I'm not sure with the N7, but with my SGS III that's what happened when it bricked.

Yeah... very strange. I'm able to get into the bootloader without a problem... only through an app.

Can you attempt to reflash your recovery?

Could you double check you are pressing the right buttons based on these instructions:
[Info] Guide to entering safe mode, bootloader, stock recovery
You are NOT supposed to press 3 buttons, Vol+ and Vol- and Power as you described, rather just 2 buttons depending on whether you want recovery or bootloader.

Well now I feel like a total dimwit.
I guess I was so used to my Galaxy Nexus... I did a Google search on how to access the N7 recovery but I guess I glanced over the instructions too quickly.
This thread can be locked, lol.

BTW sorry, I fixed the link.

download mode

Im having a really hard time getting my LG to download mode. I have the verizon version and I am pressing volume up while trying to reboot and plugged usb in at the same time. I followed the steps in the thread to restore back to stock. I am even trying my roms extended reboot which is malladus rom but instead of rebooting to download mode, it keeps rebooting the phone.

If you're able to do so, you could use the app called Rebooter. Gives you options to reboot into several modes.

Try turning the phone off. If you can do that hold the vol+ button then plug in the usb. Will boot to download mode. If you cannot power off completely, leave the usb plugged into the phone and computer, power off, and as soon as you feel the haptic feedback from the reboot immediately hold the vol+ button. I had a bootloop and that's what I had to do to get into download mode to relfash stock.

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!

The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...

you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
