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

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?

Hey,
My LG G2 802 is fully bricked now. I can't get anything alse that LG splash screen, I tried entering download or fastboot mode but with no luck.
It happend when my ROM flashing software crashed in the middle of process.
Help me out guys.

i have the same. No download mode, no recovery. Ubuntu don't recognize my G2 (i try all tutorials). Only i saw LG screen. When i press vol- and power 2 times i have option FACTORY RESET but when i do this i saw only FACTORY SETTINGS PROCESSING and stop at this. After restart only LG.

Exacly the same story with factory reset.

1. un plug device from wall or pc
2 make sure phone is all the way off (hold down power and volume down) untill it stops booting
3. hold volume UP while plugging device into pc
4. follow these instructions to return to stock http://www.droidgreen.com/lg-g2-official-stock-android-firmware-rom/
5. allow usb debuging in dev options and install unknown sources in security
6. to root your device go to towelroot.com download apk and install
7. to flash custom recovery use freegee its found in playstore

my phone havent got download mode. I flash KDZ on blue dots downlad mode. After this my phone has bricked. Only black screen. After this i have flash on ubuntu partitions and twrp. Ewerything was ok but after restart my phone dont go to TWRP. Only LG. Now i cant do anything. I havent got download mode and after VOL- and POWER my recovery dont do anything. On monday i will send my phone to service.

IT WORKS!
Well.. problem has been solved almost it self. As I said before I was trying do hold volume UP and plug it to the computer. But phone was showing only the LG logo and that's all. Linux didn't see it either.
When every idea was used I tried to completly discharge it. When it turn off i tried to plug it in and check what happens but AGAIN I saw only LG splash screen and I left it in that way. I came back after maybe 10-15min and I found phone in Download Mode. Linux saw it and without any problem I installed fresh ROM.
Really I can't explain this but it's just happend. So my advice, try any possible solution and method.
Good Luck guys!

Glad to here sound like your device wasn't fully powered off patience is pretty mine say on download mode doing nothing fir 10 minutes once [emoji106]

Thank you, Ick56, for the ray of hope you've given me. My G2 is fully discharged since yesterday and I'm on the same boat as you - no recovery, no download, no fastboot, not detected by the computer. I'm trying your way now. My question is - when you plugged it in fully discharged, did you hold any buttons?
Thanks again and thanks in advance!

Thank you for your answer, but I wasn't asking how to get to download mode. I was asking the OP what he did when his battery was fully discharged.

I just plugged it in to the computer. Yes, it's sounds ridiculous but in some way after few minutes it worked. Maybe try it with volume up too, who knows what will happen ;p

Thanks again. Here's what happens:
1. While unplugged, I entered the Factory Reset mode and left it as it is (didn't push any buttons) in order for the display to drain the battery;
2. When the battery was drained the phone went off;
3. After waiting for a few seconds I plugged it into the computer;
4. The red led was flashing for a minute or so and then the LG logo came on;
5. I'm now waiting.
Will post again when/if anything happens
EDIT: Almost an hour now and still only LG logo

i have the same.

If your light flashed red that means it is charging you HAVE to hold the up volume WHILE plugging it in in to enter download mode DONT DRAIN BATTERY TO COMPLETELY POWER OF HOLD VOL DOWN AND POWER UNTIL OT STOPS BOOTING THEN PLUG IT IN WHILE HOLDING VOL UP

Stock AT&T phone: no download mode

I've rooted dozens of phones over the years, but I have a G2 which has burned up many hours now and, despite my efforts, is still fully stock AT&T other than a SIM unlock.
LG-G800
Rev 1.0
5.0.2
Kernel 3.4.0
Build LRX22G
Version D80030f
Every amazing one-click root script/app I've tried falls at the same hurdle. The phone simply will not enter download mode. When I manually try to enter download mode (power off, volume up, attach USB), I end up at the battery charge status screen. In this state, no USB device appears to be exposed, unrecognized or otherwise. Using adb reboot recovery simply reboots the phone as normal, starting with the LG logo, then the AT&T logo. I guess this is what all these scripts are doing because the behavior is the same and they all fail because they give up trying to connect at this stage.
The only references to this state I can find online are from people who have been rooted, installed a custom recovery and then taken an OTA update. That is not my problem. This phone has always been stock. I started the whole process with a factory reset, so I doubt there's any point in doing that again. I've even found references to shorting pins on the main board to do the hardest of hard resets. It's hard to see how that could help in my case, but all advice is welcome!

Well you probably cannot enter download mode due to the fact you aren't pressing the right buttons. You need to power off the phone, hold volume up, and while holding plug in the USB.

Yes, I did make a typo in my original post, but be assured that I've tried every combination. The volume control does not work very well on this phone*, so there's a chance that could be stopping me from getting into download mode manually. It does not explain why the USB commands do not successfully boot the phone into download mode.
*I've been living with the bad volume control, but I've just ordered a replacement part on the off-chance that this is what is stopping me from rooting.

Since you are rooted try nuking download mode then reflash it.

Nope, I'm not rooted because every method of rooting I've come across requires download mode in some way. Getting root is really what this thread is all about. The phone is still fully and stubbornly stock right now.

Black Screen

My Nexus 7 (2012 wi-fi) won't turn on anymore. The screen doesn't show anything, not even the bootloader. When we plug it to the PC, it seems to be recognizing a different device (such as a camera, I don't know) and just for a second not even installing the drivers.
After asking a technician, he found that the battery (working with another N7) was working properly and no damage was found. Is there any hope? Anything we can do?
Model: Nexus 7 wi-fi (2012) - 32Gb
Was running: A custom ROM/kernel based on android 5.1.1
When Plugged to pc: APX device
Thanks

If you are lucky, the device is stuck in APX mode. Let it charge for some time (1-2 hours) and then press the power button for at least 20 seconds. In that case the devcie should leave APX mode and you should be able to boot to bootloader / recovery / ... again. If not, I suppose some hardware issues with your device.

I didn't work

I did that, I checked the battery charge with my other nexus 7 (my mother has the same tablet) and I long pressed the power button but nothing happened. In the other hand, I plug it to the pc again and it recognized an APX device "installing" the drivers (are installed but don't do anything). I read other forums about APX mode and i tried the button stuuf plug/unplug they were talking about other things that i don't unerstand.
I will edit the original post to bring more information. Thank you

N7 (tilapia) stuck at logo - no fastboot access ...

Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
--------------------------------
Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.
Rgrds,
Ged.

Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad

Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.

Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
I have a new paperweight
