Hi,
I've just received my Nexus 4 today.
I tried the phone and it was working great. So, I decided to root the phone.
I installed the drivers, unlocked the bootloader and rebooted the phone without any problem, but I noticed something strange, when I installed the usb drivers, I couldn't browse of transfer files to my phone, I thought it was just a bug and I said I would remove the usb drivers after rooting the phone.
After unlocking the bootloader and rebooting the phone, I powered off my phone, but it doesn't want to boot again.
All I did is unlocking the bootloader, I didn't root or flashed any rom or the supersu yet.
Anyway, after several times of pressing the power button and the volumes button, it booted again into the fastboot, and the first thing I did is re-locking the bootloader in case I can replace my phone if there is any problem with it.
I rebooted it after re-locking the bootloader, and it worked again.
For some reasons I decided to reboot my phone, and I did it while it was plugged to my PC.
Now the same problem happened, it doesn't want to run again. I tried every button combination (Power button for 30 secs) (Power + Volume Up) (Power + Volume Down) (Power + Vol Up + Vol Down). Nothing worked. It's completely dead.
It's not completely turned off because when I plug it to my PC, a new devices appears in the device manager but there is no driver for it.
Also, when I press the power button for 30 seconds while it's plugged to the PC, a red led light appears for few seconds and it disappears again.
I figured out that the problem happens when I reboot the phone while it's plugged to PC.
Now the phone is dead, and doesn't want to boot again.
What should I do? please help.
P.S: The battery was 100% charged when the problem happened.
This case is somewhat similar to mine.. I still havn't found a solution yet ....
Nevermind, I found a solution.
I charged it for 15 minutes, then unplugged the charger and pressed power button + vol up + vol down simultaneously, and it worked.
My battery was fully charged though. So, I don't know why charging the phone solved the problem.

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?

With this options is nothappening nathing just again is going to restart it every 2 seconds. Vol up + vol down + pwer button on more of 15 sec is going phone on power off.
I made relock on bootloader because I wanted to take it away waring: your phone is unlocked an can't be trusted ....
well...youve learn the lesson the hard way...you just cant get rid of that nag screen...
only thing left now ( i think) is to ... send it to huawei for ressussitation...
cuz at that point i dont think theres a method after loosing ADB access

Hi! Have you repaired your phone? If not, the way is easy. You need plug USB cable and hold Vol-. You will enter bootloader. You should again unlock bootloader with your unlock code. After that bootloop is gone.
It could be that phone won't enter bootloader. In that case you should power off phone. Possible needed to disassembly and eject battery cable. After that plug USB cable and hold Vol-.

I have same problem too, and I bought the phone from china, can not return back, any solution ?
Hi...what have you tried till now ?
try hold power off button for around 30 seconds...
then try VOL-DOWN+ Power while plugged to pc....
i had same problem today. Thought i have ruined my phone. But trying to rebooting the phone while using variuos options with power volume up and down accidentally succeeded. It was in my case holding power and volume button until stopped appearing reload every 2 sec, then i have released the power button while kept holding volume up button. And lucky i booted in to Huawei erecovery mode. From there I have booted my Huawei Nowa phone in to a normal boot. Hope it helps somebody.
Hello.. i have the same problem here. It keep restart after 2 seconds. When i push the vol up + power button, it goes to recovery mode. Ive done wipe/reset factory n wipe cache. And still i cant switch on my phone.
Huawei Nova Plus MLa L12 restart every 2 seconds..
When it restart too fast, im also can't enter twrp and fastboot..It restart too fast and vol +- can't detect..If anyone have solutions for this problem, please inbox me..Thanks.
Hello i have the same problem, I tried all the combinations of the power button + volume button + and volume button -, but nothing works, I even disassemble the phone and disconnect the battery, then connect the phone to the pc with the cable, but nothing works, are there any other proposals?
same here... any sugest?
Hi, I get this phone yesturday... I've installed last firemware ( 6.0 to 7.0.1 ) and after I tried with Tuliptool to install recovery but after this my phone dont show recovery when I tried so I was thinking I've forget to Unlock it before... and obvously I tried to unlock ( with tulip ) but I got error message in cmd ( I don't remerber... ) and now it show only Zte and it bootloop on it so I didn't have recovery, I can't use edl because I can't boot.. so there is something I can do or I bricked it in less than 1 day.. ? :S
Got the same problem
EDL can only be entered once the phone is completely off. You need to hold down volume up + volume down and then plug in the usb cable (dont touch the power button). The phone wont do anything, it will still look off but you will hear the device plugged in tone in Windows and will be able to find the device in zadiag. Also after a few attempts Windows stopped showing the device and I had to restart Windows before it worked again. Can you get this far?

no my phone is just showing ZTE when it is booting then just instant turns off and starts again showing ZTE and it is doing that until the battery is empty
I did have that before, I'm not sure the exact combination I used, charge it up and then remove the cable, hold the power button and either the volume up, or volume down or both for anywhere between 5 and 20 seconds before letting go and seeing if it stays off. If it doesn't work try again and again and again, Its completely trial and error and took me a while to get it to work

I'm not quite sure but on the European version of the Axon you can't do that by holding the buttons.
I understand that the only way to get in edl mode is software, no other choice than rebooting from the OS using the command adb reboot edl. So if you can't make your device completely started first, i guess it's bricked. But maybe i'm totally wrong.

I also messed up mine. I did everything until I had android 7, rooted, but lost IMEI. then I, THE IDIOT, tried to re-flash stcok android 6......booom. bricked.......
however.........power the phone off:
hold vol- power for 10 secs. phone should boot into FTM. then power it off by pressing power for about 5 secs. phone is off.
now vol+power and the phone should go to recovery, even if stuck on the logo, my pc reads it as recovery in adb devices......
tomorrow I'll see if I can get out from there. my experience doing this before is that from the recovery the ADB reboot edl works
cheers
So basically my phone has discharged and after plugging it to charger, it turned on itself and freezed on this screen... I tried to go to fastboot and recovery and holding power button but nothing helped.
U have broken verity. Only fix is to run the tool
Problem is fixed, holding volume up and power button for couple of seconds worked.
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.
