Nexus 5 stuck on google screen

I found my phone stuck on google screen. My phone is not rooted. I can get to fastboot mode, but when i select Recovery mode I go into google screen again. What do I need to do, is there a way to copy all my files from phone to pc so I dont lose them when I reset my phone.
Try to flash recovery(TWRP) from fastboot then flash any ROM.

Connect your phone to PC with USB
Type the following commands
Verify that the phone is recognized
Code:
fastboot devices
To Boot to TWRP
Code:
fastboot boot recovery.img
If you are in TWRP go to 1) wipe
2) Advanced Wipe
3) select dalvik cache & Cache
4) Wipe
5) Reboot
If that didnt work I would recommend to install it.
To Install TWRP
Code:
fastboot flash recovery recovery.img
To Reboot
Code:
fastboot reboot
Download TWRP from Here. Also any issues with ADB you will find help in the same thred

I had the same problem when I first time rooted the phone. This comes sometimes when you unplug the USB cable in bootloader mode or with adb connection. Why power + up and down? Just hold the power for 15 sec (at black screen) after try turn on. If doesnt work, put the phone to charger and leave 3-4 hours and try again. This always work for me.

How to install TWRP into the LG P500H from Koodo?

I have a Koodo LG P500H. I am having a very hard time installing TWRP.
Firstly Play store doesn't work. It has this old thing called "Market" that has some apps, but not all. Market eventually gets updated to Playstore, but I can't even find TWRP manager. There was another app in the Playstore that I tried called ROM Manager. It said it installed TWRP for me. I restarted the phone, and nothing happened.
Restarting and Holding power/volume down/home will show a picture that seems to be some sort of recovery mode. But it only run for 1-2 seconds before the phone restarts itself. Nothing happens.
I tried to use ADB. But after rebooting the device it just restarted without ever going into recovery mode. So the flash command just get stuck at "Waiting for Device." Does this phone even have a recovery mode?
This phone doesn't support Odin.
I am used to using TWRP. Without it I cannot flash the phone into new OS.
And every single time I fail, the whole phone seems to have reformatted. So I have to enter in my wifi password and gmail again. All of that typing on a very small keyboard takes a lot of time. I had spent hours on this phone without getting TWRP working.
Please help.

The problem is when I reboot into fastboot (adb reboot bootloader), the phone will go into "phone off battery charging mode". It never actually goes into the bootloader.
Ok I did the following and it seems fastboot and TWRP works now. Be sure to enable USB Debugging on your P500.
1) Fastboot tutorial (I did everything here. I hit "ok" on the LGMDP 1.5 tool as needed. Do not wait till the countdown timer goes to zero.)
http://forum.xda-developers.com/showpost.php?p=15122833&postcount=100)?
FastBoot Tutorial
1. Please download this (or from here) file and unzip it in to any folder.
2. Start LGMDP 1.5 tool with the phone connected (you need to have USB drivers installed) and click on Select Port
3. A separate window should appear like the one below
Just click connect
4. Another window will take shape (LGE Mobile security) with lots of options (links)
Click on the first upper right Browse and select the folder in with you have unzipped the files. You will get some errors that some image, table or headers are missing. Just click OK and in the end everything that should remain selected is Partition Table, APPSBL Image Header and APPSBL Image.
Now just close the window (click on x)
5. Now you are back on the main window and here you'll have to click on Download
6. You are almost done and from now on everything should go on automatically.
NV Backup
Autorestart in Emergency\Download mode and upgrade the files (you selected on step 4)
NV Restore (the last step) Do not disconnect the USB cable until the restore is done
Wait for the phone to restart in normal mode (your current rom).
That should be everything you need to do to get fastboot enabled.
Click to expand...
Click to collapse
2) Install PdaNet+ (This was the only thing I did in this tutorial. It fixed the usb driver and the fastboot can then communicate with my PC.)
http://forum.xda-developers.com/showthread.php?t=1350733
http://pdanet.co/a/
(Note: On top of Partition Table, APPSBL Image Header and APPSBL Image in step 4, I also selected the TWRP image file as my RECOVERY image. Not sure if this make a difference. )
(Note 2: I think you can also get the LG drivers here.)
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)
5) Type fastboot reboot
6) After the phone restarts, type adb reboot recovery. TWRP runs for me. Power+Home+Volume Down (3 button combo) also works now. (Previously this would reset the phone.)
Hey Man, im glad it worked. I could use your help.
I bricked my phone and need the restore file, Do you think you could make a backup from TWRP and upload it?
I would be super grateful.
Thank you.
Here is a zip with CM11, twrp 3.0.2.0 and Gapps for CM11.
Its the best rom I found.

Hi. What is your "brick" like? Does your TWRP still run? If yes you can just copy a custom OS into your Microsd card and install it from your Microsd.
You can also use ADB push to move files from your PC to the phone.

Sent from my MT2L03 using XDA-Developers mobile app
If you TWRP doesn't run, you need to install that first. Do steps 3 and 4 in the above post to boot into bootloader and install TWRP.
3) Restart, hold down power + home to boot to the fastboot. Or in ADB type adb reboot bootloader.
4) Open ADB (while phone is still in fastboot mode) and type fastboot flash recovery twrp.img (after downloading the TWRP image, renaming it and moving it to my ADB root folder. I am using TWRP 2.8.0.1 here.)

TWRP recovery menu not showing

hi, im new in this android arena and this is my first time using smartphone so please forgive my noobness.
i want to root my phone Xiaomi Redmi 5A and i follow some tutorial on youtube where he told to use Minimal ADB & fastboot, TWRP, lazyflasher noverity and lastly Magisk.
im flashing my phone using this command on ADB:
fastboot devices
fastboot flash recovery twrp.img
fastboot reboot
i guess this is it so im rebooting my phone to get into twrp recovery mode by pressing volume up+power but it showed xiaomi stock recovery instead not twrp recovery.
so what i do wrong that i cannot get into twrp recovery menu?
please help me

Is the TWRP flash successful?
Ensure that your mobile drivers are installed properly on your pc and that you've enabled USB debugging.
Now after connecting your device to the computer :
1)open adb
2)type adb devices, if it shows a serial number then proceed
3)adb reboot bootloader
4)fastboot flash recovery xxxx.img
After this, remove the USB and reboot to recovery by Holding the appropriate combination of keys.
If you reboot your device first, and then power off and reboot to recovery, you will still get stock recovery.

Easiest thing to do is use LMSA. It's available on Lenovo's support page: https://pcsupport.lenovo.com/au/en/...r-list/component?name=Software and Utilities.

I can download the ROM through LMSA, but not flash it.
Trying to do so yields a "complete" message from LMSA after only a few seconds, but then rebooting the device only gets me back into TWRP.
I also tried to flash all system_xx.img from the ROM using fastboot flash system system_xx.img ,
and to flash all vendor_xx.img from the ROM using fastboot flash vendor vendor_xx.img.
Fastboot performs this operation, but then rebooting gets me back into TWRP again.

Tough one! Try this. It will wipe your data partition, though.
If it will let you, power down the tablet for about 10mins. Then boot into TWRP. Go to "Wipe" and swipe for Data/Factory Reset. Reboot.
If the M10 still won't boot, in TWRP re-format Data (by typing 'yes' under Wipe->Format Data), and wipe cache and Dalvik Cache. I think dalvik is under Wipe->Advanced. Factory reset again. Reboot.
As an absolute last resort, you might try fixing permissions in TWRP under "Advanced". But I don't think that's going to do much, because you haven't booted the ROM successfully yet.
Hope one of these works for you. Let us know what worked for you. If nothing works, PM me and we'll try some other things.

I followed the instructions but on the last step of rebooting to system the device restarts, shows the Lenovo logo then it goes to a black / blanks screen. It appears to have shut down. I must hold the power button for several seconds before it wakes up (or restarts?) and does this all over again -- shows the Lenovo logo then black screen.
For the record the device was already rooted with Magisk. I was just trying to do a TWRP backup but found /data mounting errors so tried following steps 6 & 7. At the moment the device refuses to boot up. I am unable to get back into Recovery Mode. The ONLY thing i can do is get into FASTBOOT mode and issue commands from CLI.
The following hardware key combos produce the same results -- tablet turns on to show the Lenovo logo, after a few seconds the screen goes black (the device appears to have turned off):
x Power key
x Power Key + Volume Down
x Power Key + Volume Up
x Power Key + Volume Up + Volume Down
** Release of keys is done once Lenovo logo appears
Any ideas?
UPDATE
I went ahead and performed: fastboot flash boot boot.img << the boot.img was the earlier patched magisk image i used to get the rooted working tablet.
After performing the above the tablet turned on and is now showing the Lenovo logo however it does nothing else --- it remains on the logo forever. I am able to get into TWRP recovery. I went ahead and wiped Dalvik, Cache, and Data. Rebooted to System but still it is stuck on the Lenovo Logo.
The device if fully charged.

Any ideas?

You could try recovering the tablet with LMSA. See this post. You'll lose all your existing data and setup on the tablet, though.
Not sure what went wrong for you. Do you have a TB-X605F with Snapdragon 450 SOC? The existing TWRP is only for the SDA450. I'm working on one for the M10s with SDA429.

Thanks for the response. Yes mine has the Snapdragon 450. I will investigate the LMSA. Been messing around all day but made no progress -- not even QPST is working out.
