first things first, I recently joined XDA and was wondering if you could help me with this. So, here it goes....
I wanted to downgrade my Tablet with the 4.4.4 Kitkat rom, while currently I was on lollipop. I tried it, carelessly knowing the consequences, then here I am wasted
Now it's kinda soft bricked, it doesn't boot. but it does load to fastboot when I press power button + vol up + vol down. my father would get mad If he knows about this.
is there any way to fix this? some threads related to this were closed and some download links were broken.
HALP!

Hey guys,
I know there is already a thread out there (which I also posted in), so excuse me for my impatience, but I really want to fix my N4...
So I unlocked my Nexus 4 bootloader, tried to root it, thought I did but then SuperSU failed and failed and failed and I couldnt get it to work. I didnt make a Nandroid backup (silly me). I got sick of it and tried to unroot/lock my N4 again, using the "How to Unroot Nexus 4 to Stock 4.2 Jelly Bean on Windows!" youtube guide. In that guide, I fail on 8:45-ish where he sees the dead android and then accesses the recovery menu by pressing the 3 buttons. My N4 just reboots or shuts down. So here is the deal:
- I unlocked my bootloader and rooted my device, only it wasnt rooted when I was finished and after a lot of trying to root it, I wanted to flash stock android on it (4.2.2 according to the guide).
- Everything went well untill I had to factory wipe/reset my N4 (youtube guide at around 8:45). When I press power + volume up + volume down or power + volume down or power + volume up my N4 just either shuts down or reboots. When I try to boot normally I am stuck at the nexus X loading screen.
- Now, I cant boot my nexus, I cant wipe my nexus, I cant access it from the PC using ADB and I HAVE NO IDEA WHAT I CAN DO.
I signed up specifically for this issue and I feel like such a douche, because it was running smooth with 4.3 and I just wanted to try out more of Tasker...
Please guys!
The correct button combo is volume up and power. Your phone is most likely rebooting or shutting down because you're holding the buttons too long. Press power and then volume up briefly and quickly let go. The menu will appear.

I got ninja'd by El Daddy and can't figure out how to delete my post.
That seems to be a very specific button combo indeed, I tried it so many times before and I failed miserably. Thank you so much.
I should make a back up more often! I have been stressing over this for two days...
Fixed my problem now...sorry to have bothered anyone
Please ignore this thread.

I was previously rooted and running 5.0.2 so I decided to try one of the CM rom's out. I ran into a little difficulty and now I am suck on the Samnsung logo on boot, holding down the power button does nothing and I tried holding volume up + home + power and it wont respond.
Have I unintentionally bricked my phone? Is there a solution to this? I'm going to be majorly gutted if I have just ruined my phone so if anyone has any suggestions please help
Thanks.
Hello guys
i was trying to install Alexis Rom 5.5.1 on my S8 i had to Flash a new Bootloader i've flashed it my phone restarted and was stuck in a bootloop i turned it off by pressing vol. down butten and the power button , when i wanted to restart it i couldnt i've tryed evey other button combo but it just wont turn on .
Is there a possibility to revive my phone or can i throw it away ?
Sorry for the bad English
Okey found a solution just in case if you have the same problem your device is probably not hard bricked its on and not responding so just leave the phone for 24 hours or less and try to go into download mode (vol down, bixbi,power button).
Good Luck
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...

--------------------------------
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,

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
Okay , i have to admit, this device is **** for doing basically anything related to custom roms and installation flashes.
Note: I am just a noob, as i got to know what rooting and all this stuff is only like a week ago. So please correct me if i am wrong. All the stuff i post here will be things i did to Get out a bootloop. I'll try and update this thread if i can, but no guarantees cuz honestly i don't know what i am doing half the time lmao.
Anyways hopefully somebody else confirms this stuff:
Also i used LineageOs 17.1, NikGapps signed and magisk 21.4, i had NEVER had problems with twrp and fasboot itself, only problems with GETTING to TWRP and fastboot. if fastboot or recovery is damaged then idk what to do, because it never happened to me
These occured for me when i downloading wrong firmware/ wrong gapps and once when I tried to update gpu drivers, but it just soft bricked my phone:
Okay enough chat, here is the stuff i did to fix a softbrick:
Step 1: if you are stuck on a pure black screen you have to do is hold power and vol up until the realme logo comes back on. Although this is the toughest part to resolve as it didn't work for me consistently. (i tried only power for a minite, then power + vol down, then power + vol up and then suddenly on one power + vol up it started working and put me onto the realme logo).
Step 2: if you are now on the frozen realme logo ur basically chilling. (But also note: when i was trying randomn stuff on the frozen logo, i once felt two or three vibrations and then i went back to the pure black screen. )
Hold Power + Vol up until you feel a vibration and the second u do, keep power+ vol up held and also start holding vol down.
Step 3: thats basically it. U should on fastboot.
if anyone wants to correct me, because there is a chance that i am totally wrong, please do so. I just posted stuff that works for me because i know i can't be the only one who enocuntered this.
if this helped fix your phone please let me know.
Also note that i dont take resposibility for making things worse because i am only speaking empirically. I tried like 10 things, some of them workd and i posted them here. I dont know much about rooting and development yet so please dont hate me if i made things worse.
