[Q] Can't boot. Stuck on Google logo - Nexus 4 Q&A, Help & Troubleshooting

Hi,
I really need some help on this one. I wiped everything using TWRP recovery in preparation of installing a custom ROM.
I then realised I forgot to transfer the custom rom to my phone! When I went to reboot the system it says "No OS installed! Are you sure you want to reboot?"
No it's stuck on the google logo.
Is there a way to see if any Rom is still installed on on my phone or if it deleted my stock rom also?
I tried to push the rom through adb but it says error read only.
Also USB debugging is not enabled but I can't boot to enable it.
Please help.
Thanks

Go into fastboot and ensure your fastboot devices command shows your s/n. If so then grab the stock image from xda and flash it.
fastboot flash bootloader BOOTLOADERNAME.img
fastboot reboot-bootloader
fastboot flash radio RADIONAME.img
fastboot reboot-bootloader
fastboot -w update IMAGENAME.zip
Alternatively, using ADB.
from command prompt: adb remount
adb push <FILE PATH> /sdcard/0/
Boot into recovery (I use CWM) and then install it.

Thanks for the quick reply.
I managed to solve it by using the instructions in this thread: http://forum.xda-developers.com/showthread.php?t=2010312
It's all in fastboot so I had no problems
Problem solved.

[Q] ADB sideload & fastboot not working

Hi,I just installed android 4.4.3 from 4.4.2 rooted with kernel mat1x v13.5 with the following steps:
adb reboot bootloader
fastboot flash bootloader bootloader-mako-makoz30d.img
fastboot reboot-bootloader
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.02.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot format cache
fastboot reboot
Then installed CWM by:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-touch-6.0.4.7.img
fastboot reboot-bootloader
and then I tried to go to recovery mode with:
Code:
fastboot reboot-bootloader
but the command line says:
Code:
<waiting for device>
. If I write:
Code:
fastboot devices
, nothing happens, but if I write:
Code:
adb devices
it does recognizes my phone.
Anyway I went to recovery mode with volume buttons (CWM is properly installed), went to sideload options, USB connected and typed:
Code:
adb sideload UPDATE-SuperSU-v1.99r3.zip
but it says:
Code:
error: device not found
While I'm in Recovery mode (in CWM) adb devices can't find any device.
SDK tools and platform-tools are just updated and PC is just rebooted.
EXTRA INFO: when i go out of CWM it says:
Code:
Root access is missing. Root device? THIS CANNOT BE UNDONE.
and options are
-no
-Yes - Root device (/system/xbin/su)
When I choose Yes it just starts with no problems.
Anything?

Try reboot the phone and then reboot to recovery and see if that works. If not, try TWRP recovery.

You mean turn off the phone and turn on to recovery? Because I've already done that as I mentioned in the first post.
Not sure but aren't recovery mode and fastboot mode different?
Can you manually boot into fastboot mode on your phone rather than using adb commands?

I just used fastboot to go into recovery with my pc because i'm lazy, I can do it with the mobile, but when i tried I discovered the <waiting for device> error. And I need to use adb coomands to sideload SuperSU. I think i can flash it from the phone, but it still bothers me the fact that there is something wrong, because I use my phone to test personals apks.

Are you using a Windows PC? If you are, boot into task mamager and kill all ADB services. Relaunch the command prompt and try it.

I assume the drivers load the first time you connect your phone. Does running the command prompt as an admin make a difference?

Ok, but ADB won't recognize my device when it's on CWM (CWM v6.0.4.7)
I realised that in "device manager" of Windows a yellow triangle appears on "Other devices" -> Nexus 4 (when im in Recovery)
and when I normally boot my phone it appears normally under "Android device" -> android composite adb interface
No clue?

[Guide] Most Problems and Info's that you must Know about ADB and Fastboot

Tips & Guides About Moto G 2014 ADB and FastBoot
The most of people have problems with fastboot and ADB. Here will explain some tips and guides.
- Do u know can use ADB in recovery mode?
Yeah if u have bricked your phone or deleted system or can't put the Debug Mode have a alternative. This happens the Device ADB have two modes. The USB mode and Debugging Mode, using two different drivers. When you download Motorola Device Manager he installs the Debugging Drivers. In Motorola is really hard obtain the correct drivers.
- Can I flash zips with fastboot?
Yeah but isn't recommended the people try that:
- fastboot flash zip myzip.zip
This is incorrect he will try to flash a .IMG in a partition called zip.
- fastboot -I flash system myzip.zip
This is incorrect. When you download a ROM backup to flash in Recovery he have some partitions making that will create a partition into a partition. Bricking your device.
The correct way to flash ROM is in recovery.
- I can't transfer file on my device.. Can I flash?
Yes using two methods
- ADB push
You push to your device a .zip with the Rom eg.:
- adb push my file.zip /sdcard or /sdcard1
This will push your file to the device and you can after that flash in recovery.
Is normal after digit the command nothing happens. Differently fastboot the ADB doesn't shows progress of transfer.
- ADB side load
You can flash sideload the zip
Using adb sideload myzip.zip
Must enable sideload mode on your recovery.
- my device doesn't appear on the list.
When you are on boot loader mode the ADB doesn't runs. Only in recovery mode or system mode.
Most times you have incorrect drivers. But if u are on recovery mode try that on cmd:
adb kill-server
adb usb
This will enter the daemon service in USB mode.
- can I reboot my device in recovery? Yes, adb reboot recovery
- can I wipe my firmware with fastboot? Yes, using these cmds.
fastboot erase userdata
fastboot erase cache
- can I get my device info?
Yes with ADB.
adb get-imei
adb get-serialno
adb get-deviceno
If u have more questions write here. I will add on OP.

Getting your device connected is a very important stage, whether it is system,recovery or fastboot. From what I read , you can connsct through fasatboot, since you flashed cyanogen. Just flash TWRP 3.2.1 or so which is the latest, through fastboot:
fastboot flash recovery twrp.3.2.1 .img ( Remember the spaces, the name twrp.xxx.img should be same as you downloaded. If flash is successful, you can see twrp when you boot to recovery. Then flash supersu file and/or whichever rom you want.
Sorry for late answers.
I was lil busy and sorry for wrong address also.
You could get it from firmwarefile.com
I can't post link here but select yu yureka plus variant and download oldest CBP

Stuck loading twrp

Hi,
When my S7 Edge boots up it jumps to twrp but it's stuck on the teamwin logo screen and does not advance to menu.
This happened after I tried to format the data partition to ext4 via twrp and it just got stuck there too so when I rebooted it landed in this situation.
Unfortunately reflashing twrp or reflashing the stock rom via ODIN does not work as COM3 is recognized but then when I press start it doesnt do anything....
Also tried the suggestion I read online of:
fastboot format cache
fastboot format userdata
These commands just get stuck on <waiting for device>.
Also tried adb shell recovery --wipe_data but it gets stuck at I:LANG: en
Any help will be much appreciated!
Thanks
This is how I solved it in the end.
With cable connected I did:
1. adb push boot.img /external_sd
2. adb shell
3. dd if=/external_sd/boot.img of=/dev/block/platform/155a0000.ufs/by-name/RECOVERY
4. fastboot format cache
5. fastboot format userdata
6. adb shell recovery --wipe_data
7. adb fastboot recovery
Notes:
The boot.img was obtained from a downloaded stock rom image and by decompressing the AP file (just open it with 7Zip) and then you need to uncompress boot.img.lz4 with 7zip zstandard (look it up)
Step 1 took sometime to run since TWRP was stuck loading using a lot of CPU as phone was really really hot!
Sometime I needed to do a adb fastboot recovery and then quickly run and rerun command in step 1 until it succeeded.
Step 6 is redundant but is there just to be safe.
After this you are booted back to a stock recovery where you can use Odin to flash what you want.
In my case I flashed a stock rom and then flashed TWRP again.

Same problem and question here

Cannot boot in recovery after TWRP update

I've a big problem, and I hope someone can help me
I wanted to change the rom, so I've rebooted my phone in recovery mode and executed a full wipe, after that I've updated TWRP, everything seemed to have gone well so i restarted my phone, but at this point it neither boot the rom(obviously, it is full wiped) nor the TWRP can start...
What can I do? I can only start the Fastboot screen...
How'd you update TWRP? If you did it through fastboot commands, you can just flash TWRP to the recovery partition, or boot it directly.
If you didn't do it through fastboot commands, you'll need to get that to fix it. Google has links to the latest android-tools for Windows and Linux on their Android site somewhere.
From there, you'll need TWRP (either official or codeworkx's), and then you use the flashboot executable to flash it: fastboot flash recovery TWRP.img
