Help out of my bootloop? - Nexus 7 (2013) Q&A

I just bought a 2013 Nexus 7 today for very cheap, to use in my car as a headunit and learn a bit about flashing different roms, using the timur kernal, etc. It looks like it was used at some sort of healthcare facility though, because it has some "Optum Health" software on it, deeper than just an app it remained after a factory reset. On restart the optum health logo comes up, immediately after the google logo and says loading, well before it actually loads to the home page of the tablet. So it's pretty deep. I was thinking a fresh factory ROM would help me out.
I was following this guide to get twrp on the phone, as wifi wasn't working (most likely because I had tried to remove the optum stuff by disabling apps, and I got a little trigger happy) load via adb:
https://www.xda-developers.com/how-to-install-twrp/
Everything was cool until I went to restart it. I typed "fastboot reboot" into the command prompt, she restarted, and gets infinitely stuck at the "Optum Health" logo, and the word "Loading" pulses underneath.
I can't get it back to the bootloader by holding the volume buttons and "hold", the cmd/powershell doesn't see the device connected. However, the computer makes the chime sound of a device connecting when I try to open the bootload menu using the buttons, the power shell waits longer to say it failed, but it still doesn't work.
Do I have any options? Or did I completely brick my old, cheap, facebook marketplace, probably stolen from a hospital tablet?

Follow these instructions to resolve the problem and flash up-to-date Android - https://wiki.lineageos.org/devices/flo/install
"With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons." it really works.
Then connect it to a PC and install proper USB driver - https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/

Once you get ADB & Fastboot installed on your PC or linux , do a command prompt with the device connected.
adb devices
It should list your device in your terminal output. If and when it does..If your a little hinky on the buttons just do a command prompt: adb reboot recovery, adb will reboot your device for you into recovery mode. Then follow the LOS instructions provided for you & you will be amazed at how great your tablet works. Just a little FYI, if you've never done this before, find the "pico" gapps, don't try to install any of the bigger ones, there is not enough room on the sys partition for the full gapps install. After & if you get pico installed you can always add to it with all the room you have left now on the rest of the device. Also when you are installing LOS, make sure you find and install the gapps at the same time you install the OS, before you reboot your device. It will save you a lot of headaches. Just follow the directions and you will be very happy.

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work
Hi guys,
I've watched the n00b video and been googling for the last few hours as well as reading through various pages on the XDA forum. I've found a lot of problems that are kinda similar and tried various solutions but don't seem to be quite getting there.
Basically I had Virtuous Affinity as the OS and clockworkmod installed (should be the most up to date versions of both, they were put on no more than a week ago) as well. I also had a backup of current OS and so on on the SD card, as well as the original zip of the rom.
I decide I want to give ICS a go and so I downloaded the betamod ICS and then loaded it. It asked me if I wanted to do a dalvik cache wipe, a dalvik cache + data wipe and a third option I don't recall. I went with the dalvik cache wipe (at the time I was under the impression that was the correct course of action) then put it back in my pocket while ICS installed.
I get my phone out of my pocket later and it's kinda stuck on what looks like (but logically isn't, I'm guessing it was meant to be a splash screen type thing while ICS installed or some such) a screensaver which just loops endlessly. The only thing you can really do is take the battery out and turn her on again, in which case you once again end up in the endless screensaver loop.
I've tried booting to recovery using volume - and the power button and unfortunately it just boots straight into the looping screensaver again.
Getting a bit worried and feeling adventurous I tried seeing what I could do with ADB, however the computer seemed unable to recognise that any device was connected with ADB devices not listing anything.
I've read up a lot and I'm at a loss as to what to do - there's a rom on the SD card and there also should have been a backup but I just can't get it into recovery.
I do have the ability to view the SD card on another device and interact with it, so if there's a potential SD fix, that's certainly not out the window.
But yeah, I'm clueless how to proceed here and very green at the whole rom business. Can anyone advise what I might try to do from here? I don't care what state I end up going back to, or if I lose my data, I can get all that back, I just want the phone in some semblance of basic operation.
I'll be keeping an eye on the thread, if I've left out any pertinent data ask away and thanks in advance for anyone with a clue how I can fix this mess .
EDIT: Post may be better off in ICS thread above and I do apologise if so, I would move it but I seem unable to delete it.
Remove battery for 5 seconds and then try again to boot into recovery using volume -and power button.

I have, it doesn't work. I've left the battery out for a fairly long period. Volume - + power still just brings it back to the "screensaver" loop.
Thanks for the suggestion though.
Turn the phone off completely; pull the battery out for a bit then replace it and don't touch anything. Don't try to turn it on. Plug the phone by usb to your pc (still turned off). At the command prompt in the folder containing adb.exe type "adb reboot recovery" - the phone should power on and go to recovery where you can wipe properly and reflash whatever you want.
You should be able to boot to recovery using the volume down + power button combo (hold the volume-down key, then press and hold the power button and keep both held until you get to the bootloader menu); the only thing that's wrong with your phone is that you've flashed one ROM over another without wiping it first, so the ROM can't load but this shouldn't affect your bootloader or recovery.
Worst case you can flash a RUU which will restore it to the official firmware; you'll then need to re-root and re-install a recovery image to be able to flash custom ROMs again.
Very helpful post, thanks! I'll try all that and see how I go, I'll post if I still have trouble.
Yeah I dunno why I can't boot to recovery it's weird. The volume button wasn't working, so I removed it and am pressing in the volume down portion of the volume button with a pen while holding down the power button. It's possible perhaps I'm not successfully depressing volume down, but I'm 99% sure I am and that that's not it. I am however doing it as you and other guides advise, depress volume down, hold it and then depress power and hold both for about three seconds, no joy!
Anyway, as said, I'll try what you're recommending and see how I go. Thanks!

Curious what you mean by this? Cause there's no command prompt in the folder ADB is in. Do you mean in command prompt, be in the folder, i.e. c:\abd kinda thing? I tried just loading command prompt and typing abd reboot recovery, no device detected - no joy.

Yeah that was what I meant; I've got a feeling that that only works when the phone is powered off if you had USB debugging activated on the phone beforehand, so if that's not working that might be why.
c:\adb
results in error: device not found.
ADB app itself is in C:\adb\platform-tools but when I try that it goes The System cannot find the path specified. I've tried cd/adb and I can get that far but I can't get to adb/platform-tools.
EDIT:
Okay, I managed to get to c:\adb\platform-tools but adb reboot recovery is still advising error: device not found. Guessing perhaps I didn't have usb debugging enabled. Are you able to suggest another work around at all? I'm happy to flash it to whatever, I don't mind losing data, just want to get it in working order again. I don't see how I can though when I seemingly don't have access to recovery or USB...hrmm, must be some way around.
Accidental double post, sorry.
You need to try get into recovery mode, where you can do a full wipe and see if that fixes anything.
Firstly, remove your battery then re-install it, your phone should still be turned off at this stage. Press and hold the volume down button, then additionally press and hold the power butter, until something appears on the screen. If the bootloader appears, you can then boot into recovery from there.
If the above fails to work, report back with your results and hopefully something else will be suggested.

Your only other option to get into recovery is the volume-down/power-on combination. Like I said, I can't think why that's not working unless it's related to your missing volume button (maybe it's not maintaining a constant pressure on the button when you're using whatever to press through the hole).
If you still can't get that to work, I would suggest finding a stock RUU and flashing that. It's an .exe file that runs from your PC and will return your ROM, bootloader and radio back to stock. Obviously that means you'll lose root and your custom recovery so you'll need to do all that again from scratch. There's a sticky in the dev section with a link to a thread with various RUUs (it's named something along the lines of "shipped & test ROMs" - I'll check that and link to it once I've dragged myself out of bed to the computer). You'll lose all your data, but if you took a backup beforehand you can restore that once you're back up and running.
//sent from my Desire HD using Tapatalk; all errors entirely intentional.
Yeah I'm starting to think perhaps the down button is just broken.
What state should the phone be for the RUU, turned off with usb plugged in or turned on? Bearing in mind, that when on, all it will do is the "screensaver". Will it work in either of those states?
Thanks, will deffo research more when I get home. Appreciate the help immensely.

Guessing you mean that as far as the ruu thread. Am downloading a stock rom atm, with shaped internet till tomorrow, meh! Will see how I go. Have a feeling phone was probably Vodafone branded at stock though, so that could make for extra fiddling but yeah, fingers crossed.
If you are able too install a stock-rom you can work from their than install 4EXT recovery
touch than you doen't need the volume buttons.
I downloaded the most recent stock rom on the link above. When I try to install it though, phone off or on, it advises a USB connection error. Is this likely to be because I originally had vodafone stock and need to make a gold card, or should it still at least be recognising it? It does advise not to run any programs on the phone or anything when while installing the update, but of course, as long as my phones turned on it's stuck on the damned screensaver loop.
http://forum.xda-developers.com/archive/index.php/t-841890.html
Gonna give that a go, fingers crossed!
D'oh, just found out my mobile was Three at stock and not Vodafone, the search continues .
Gah, I'm about tearing my hair out here, I want my damned phone back . Stuck using a $79 Huwawei Vodafone thing at the moment and it's so so so awful.
Anyway. I was under the impression that making a goldcard would mean I could RUU a non-Three stock rom on the phone. I made a goldcard following these instructions; http://www.addictivetips.com/mobile/how-to-make-gold-card-for-htc-desire-hd/
Then I turned the phone on as the RUU advises, (meaning it's scrolling through the feckin' "screensaver") and start the process and once again get a USB connection error.
What's the better process at this stage, try and take it back to Three stock? I don't see how I can at the moment, the only Three stock I can find seems to be rom, not RUU, meaning I'd need to load from the phone, which I can't due to no recovery. Or should I keep trying to get the goldcard thing to work, maybe try some different RUU's or something?
I'm open to any other suggestions as well. Had a bit more of a fiddle around with my volume down button, no matter what I do though, I can't get recovery mode. Always boots first to the white HTC screen and then starts the infernal "screensaver" loop.

How come the volume down button be broken. When you were using Affinity Rom weren't you able to use your volume button for music. Remove SD card from phone then press "First - Volume down gently for 2 sec" & press-hold power button when it goes into bootload place your sd card back select option "REBOOT RECOVERY". I think your panicking too much just be patient nothing is wrong, i think your just hurrying it up...
The volume button didn't work before either. I had to manually adjust volume from settings. I thought it was just because of the dodgy plastic button on top, but using a pen to depress the button underneath doesn't work either.
Believe me, I've been trying to fix this for days now, every different way of depressing volume down in order to get to recovery has not worked. Short of taking the phone apart and seeing if I can see what's wrong with the button (doubtful with my level of expertise) then it ain't happening via that method.
Got a little bit hopeful with this;
http://www.htcdev.com/bootloader/ruu-downloads
But that too requires my phone to be in usb debugging mode, which of course, it isn't.
Is there anyway to force the phone into usb debugging mode using some form of hack or some such? The thing is, it is powered and everything, I can turn it on, the screen works and all that jazz and indeed the phone will charge from USB and the computer makes a noise when I plug or unplug it, the phone itself however won't do anything other than the "screensaver" ICS installation loop. I guess I'm thinking where there's life there's hope and perhaps there's some way in that state I can get it to switch debugging on, though I think I'm reaching at this point .

[Q] Help desperately needed - Galaxy Nexus not booting after installing Jelly Belly!

I really hate to join under such a condition (it's an amazing site which I thought I would join for better reasons when time permitted), but my new Galaxy Nexus just went to hell on me after flashing the (apparently) popular Jelly Belly mod.
I started with a rooted 4.1.1 Jelly Bean OS with ClockworkMod Recovery, and now it looks like disaster after using that to flash Jelly Belly - what happens now is my phone boots up to the point where it flashes that colored Google "X", but it never proceeds beyond this point. I cannot put a different mod on my phone because there is no connection with my computer, and I can't stop my device from thrashing without a battery-pull. Is there any way save this phone and put plain Jelly Bean back on it?

When I do, I have that "Downloading..do not turn off the target!" message. Why this - I did remove the supersu file, although I think I left my clockworkmod file on the root because now you have to re-flash that every time you use it. Now I have no option other than "Start" - any chance of breaking through now?

thats not fastboot, thats odin mode. use vol up and down and power button to get to fastboot mode
the entire reason your phone is behaving the way it did is because you didnt wipe data/cache before flashing the rom.
you really need to do some reading before you start modifying your phone

Do you mean that I need to continually rock the Volume key up and down while holding the Power button? Volume Up with Power put it in boot mode, and when I tried rocking it a couple of times I got the same result. It I understand you correctly, the idea sounds tricky. Is this supposed to work on a Galaxy Nexus?
press and hold both ends of the volume button and the power button... its really not that hard.

What I really should have done was slow down, or quit while I was ahead to get some rest last night! I had researched the root process for my phone ad nauseum, which I know is why I succeeded at getting ClockworkMod safely installed. By the time that was done I was tired, but I counldn't stand the thought of living without my files loaded on my phone - I was in the bad state of needing too much to complete what I had intended to do. I see I had the wrong impression that ClockworkMod would take care of the whole process once I had that working, guess it didn't. When you've been through the process of installing a hundred versions of Windows and Linux on a PC, which never needs to be pre-wiped (the new OS does that), who would have thunk it's that much different with a phone computer?
Did you get this solved? Just reboot into recovery (hold down power, volume-up, and volume-down simultaneously to get into bootloader, choose recovery using volume buttons, select using power button), full wipe (system, data, cache), and reflash your ROM.

This is another thing I never would have guessed without being told specifically, that it's even possible to hold down both ends of a rocker switch and have it do a different function - I tried this, and now it works! I had used my PC to root my phone last night, and right now I'm at work, where there will be time to go through this in a couple of hours. I took a brief look at the tutorial recommended by Zepius, and am wondering if I am set to proceed. I plan on using my work PC, not the one at home with the drivers I used to root my phone. Nobody else uses it and I have never used it for anything phone-related. Can I presume any drivers which I'm warned should be uninstalled would be on the PC which is used, and not the phone?

Sorry, I had to work, but now there's time and I thought I would try my work PC, which is virgin (so to speak) of mobile devices and drivers. It's a Windows XP system, and right now it's not looking good because when my phone is plugged in, there isn't a "Portable Devices" or "Mobile" category under Device Manager. Do I have a better chance of this working on my home Windows 7 system?

I guess that's a never-mind, I should have had my phone on! It's in Fastboot mode now, but I still don't know if what I see in Device Manager is good for what I'm trying to do. No portable device, phone, nor galaxy nexus, but what did change is I have "Broadcom Nextreme 57xx Gigabit Controller" appearing under "Network Adapters". Is this a problem to be dealt with differently when your phone is bricked?

1) your phone is not bricked. dont call it that
2) best way to check if your drivers are installed correctly
open a command prompt in the folder where your fastboot.exe is and type: fastboot devices
if you get a device ID, your drivers are setup properly for fastboot
3) at this point, just return to stock: http://forum.xda-developers.com/showthread.php?t=1626895

I got a device ID (long string of characters) on that fastboot command, but I'm still concerned that my phone won't talk to Device Manager at all. Windows 7 doesn't pop up a connection window when it's plugged in, should that be expected?
What I mean by "not talking to Device Manager" is that the only item under Portable devices is just E:\ - no device listed here! The tutorial in your signature hinges on there being a device listed "without thde yellow exclamation point", for the installation of new drivers, therefore I don't know how to follow it from here. The adk drivers which were used to root my phone (they were good, the problem began when I tried to flash a rom and missed a step or three) are stil there, but I'll replace them if I can find a process which can talk to my phone in it's present state.
On a side note (and only because it held me up in responding tonight from my Windows system), is this site partial to Firefox? I am able for the first time to login, and I wonder if it isn't because I quit trying to through my Windows 7 system. It has only Windows IE, and Chrome (which couldn't even browse this site). I am currently on my Ubuntu system with Firefox.

I said much the same myself.
For the fastboot devices test, I have a string of characters, but no device name, only "fastboot" on the single output line with those characters. Is this a valid device ID?
"...just use fastboot" Ok, but how? Should (can I) even do this use fastboot to transfer files to my phone under it's somewhat anonymous status with Windows? Since last night's fiasco nothing was named under "Portable Devices", only "E:\" was displayed. I have no graphical display in the file manager, so how am I supposed to transfer the necessary files to the root of my phone? I don't even see a way of addressing it to install drivers now.
I will need drivers because I attempted to follow this tutorial (which doesn't account for what I am (not) seeing on my system. I got as far as uninstalling the good drivers which I used last night in favor of what was offered for use with the tutorial, and now Device Manager doesn't even have a Portable Devices category. The "Universal Naked Driver" was to replace my uninstalled drivers, and interestingly the contents of it's expanded folders don't even contain fastboot (the adb package which I used last night did). In light of this, how am I supposed to have even fastboot?
I hate to be a PIA about this, but I guess I'm more a n00b than was presumed in this tutorial - it's either that or my situation really is too different that I can use it as is. Could I please get a few clues in light of what the tutorial doesn't address? Do I have any means of installing anything and transferring files with my device-PC communications as they are, and if so how can I do it? I'll give it a run if I understand how.
Thanks.

I see now that Part D calls for flashing JO03C from my PC, not the device root, ok.
Also, after rebooting my laptop, the E:\ is back under Portable Devices in Device Manager. When I double-click this I get the statement
Device: Portable Devices
Manufacturer: Generic-
Location: on UMBus Enumerator
I don't think this looks better than the Microsoft default, but is it good enough for what I need to do?
I still have the driver package android-sdk-windows, which contains adb and fastboot, so perhaps I should just use this according to Part D and see what happens?

Good god, I never should have read Zepius's tutorial - I didn't need my PC at all! If I understood what bananagranola had said, I could have saved a lot of time!
Oh, no, now I can't connect with the server!
Could I have possibly lost my radio from what I did earlier? I was able to boot up, and I was upgraded to 4.2.1 when I did the data wipe. Starting over, I should have had a prompt to connect with gmail and download my contacts, but this didn't happen. My People app is unpopulated, so I chose to connect to "sign into an account". While I am sure of my login input, it didn't recognize this, and then the process ended with a "couldn't finish - couldn't open connection with the server" error. Any clue where to go from here?
Some standard apps are missing too, including the Play Store app!

S4 mini with broken screen, no more data after 'blind' reboots to recovery

Dear All!
(I already searched Google and xda - However, since my problem is rather specific, I may be using the wrong keywords to come up with a solution that is also applicable here; so also links are highly appreciated!)
I will give you the whole story in order not to skip anything important:
While hiking with my family I somehow managed to break my screen (LCD and Touch, as far as I could tell). However, the phone was still powered on, which i could tell from using the volume keys and hearing the normal sounds. Also the phone was ringing when called.
Unfortunately, USB Debugging wasn't activated, so I booted to recovery (some CWM, can't be more specific, sorry) via several tries. It was a bit tricky at first, but i managed to come up with a routine that would work (Holding VolUp+Home, then Power additionally; releasing the power button after the first vibration and then holding the other two for another 3-5 sec did the trick).
I then could gain usb debugging the way described in this thread: [Tool][Windows] Control a device with a broken screen. Now with touchscreen support!!
Using a Linux machine I then used adb commands (ls; cd; pull) to copy my mmssms.db; however I had to leave my workplace for a short while. Afterwards my device wasn't shown in adb devices, because it powered off for some reason.
Here comes the crucial part: At this point I mistakenly booted into Download Mode (and wasn't aware that I did it, cofused VolUp and VolDown - I couldn't see that, so I'm not 100% sure). I pulled out the battery at this point and rebooted into recovery.
Booting into recovery still works and "adb shell" -> "ls" shows the folders, however apart from the top level folders there are no more files/folders left (e.g. "ls mnt" gives "fuse secure shell"; "ls data" gives "media"; "ls data/media" doesn't return anything)
At this point I mainly want to get the contents of my internal sd (now no files are shown).
tl;dr: Broke screen; accidentially booted into Download Mode; Pulled out battery; Can't access my files/files gone in adb shell
Is there a way to recover the file structure? I still can get into recovery and use adb but the phone won't boot to CyanogenMod (I suppose it gives me a soft brick screen, but i can't confirm that as my screen is broken).
I really hope someone could point me in the right direction!

Question Bricked my Prixel 6 after flashing stock rom

Hi there,
I am looking for some guidance on my bricked Pixel 6 Pro.
I transfered the data from my old pixel, but then decided to do a full flash to refresh. Downloaded the stock image from google, used the fastboot-all script to flash the phone, but as soon as it was done, I never reboot. my phone is looking completely dead since.
Attempt # 1
- black screen, with no sound to any actions of response to any key combination (power or volume keys).
- tried holding the power button for 60 secs, no response
- tried holding power and volume down, no response
- tried holding power and volume up, no response
- when I plug the phone on charge, no response. neither the charging display.
Atempt # 2
- Only time the phone shows some sign of life, is when I connect the phone to my PC, it makes a sound of detecting a device, but then instantly it get a disconnect sound, (in 2-3 sec).
- I tried holding the power button, while plugged in. it makes a sound of usb detection, (but no visual response on the phone) after holder for 30 secs, it makes another sound of usb detach.
- While I am experimentating with PC connection, I also tried fastboot reboot command, it only shows waiting for a device and nothing happens, either on the console or phone.
Not sure, if I have bricked the bootloader, and if yes, what can be done? Any guidance in this regards will be highly appreciated.
Thanks
Call whoever you bought the phone from and do warranty claim.
I struggled with a soft bricked / bootlooping phone after removing Magisk. Although my phone at least booted to bootloader and a connection via fastboot was working, the factory images wouldn't flash properly. Google support couldn't help me and I thought I had to send it to repair.
In the end I could solve the issue by switching to the Android SDK 31. I know your case is different, because your phone is bricked worse than mine was, but you could give it a try.

Bootloader unlocked?

If I remeber correctly flashing factory images forces you to unlock the device. So yes, the bootloader of rao_hamza's device should be unlocked.
From memory you can revive it through QPST and orher Qualcomm utilities, however hard part is to get the files. the phone is too new and many shops dont have the unlock tools yet.
" While I am experimentating with PC connection, I also tried fastboot reboot command, it only shows waiting for a device and nothing happens, either on the console or phone. " - this is still good news, as phone is being detected by windows, try to install Qualcomm drivers and see if you can get it to boot into EDL. GOOD LUCK.
Pixel 6 uses Google's own new Tensor chip - so no Qualcomm tools
Like @Baumhouse I went through something similar. Two things for me: it took way longer to hold power and volume down than any other phone I've owned. I was seriously concerned I wasn't going to get there. Two, the factory images all made it to fastbootd and then failed all because I hadn't updated to the latest SDK.
Just throwing this out in hopes you don't have to send it back.
What @ridobe said. Make sure you're using the latest official Google Platform Tools (there's a link in my thread at the top of my signature below if you need it, or just Google for it). If I had a nickel every time someone didn't update the tools when they went to use them...

What is EDL? and had the Google usb drivers installed, to get the fastboot working.

Yes, I don't know who to get into a bootloader in this situation, if that were working I would have some hope.
If you can get to the bootloader you can use google's flashing website, flash.android.com. I just use that to go back to stock, even with an unlocked bootloader.

Sorry, misread the post.
@pysklona came here because I'm in the same boat, hard-bricked my device after running the flash-all script. Was using the most recent version of platform tools and the brand new cable that came with the phone.
Was getting the same result, attaching it to a windows pc makes the attached device chime, but disconnects after a few seconds. It came up first as "Setting up Pixel ROM Recovery". I let it sit overnight and now it doesn't auto-disconnect and I get a serial device under com3 on windows. Attaching it to macos gives me a "Pixel ROM Recovery" device. Despite "recovery" in the name, I think it's actually in EDL mode, not recovery mode. No devices come up for adb or fastboot on windows, linux or macos. Screen is completely blank no matter what.
Not being a Qualcomm chip makes this whole process from here a bit of an unknown, but will assume the process for recovery is more or less the same. Looking into QPST/MsmDownloadTool/OpenPST, although as pointed out, I'm not sure any of those tools will work since this isn't a qualcomm chip. MsmDownloadTool is for oneplus, but maybe something can be modded.

Thanks for sharing your experience. I just returned the device and got myself a new one.
anyways, i am not sure what is causing this hard brick. thats is something we all should be careful about it.
same thing here. pixel 6 from google store. magisk installed on the december update and i downgraded to the november one using the flash-all.bat script. phone reboots and am told the software is corrupt
reboot back into fastboot mode, run the script again. and get this software is corrupt message again
this time I cant' even boot into fastboot/bootloader mode. and plugging the phone into windows gives me the "pixel rom recovery" message
phone seems dead (black screen, not responding to hardware buttons)
any other solutions than to get it replaced?
Hmm, maybe plug it in to a PC via USB to supply it with power (maybe the battery is down) and just do a very long press of the power button - at least 30 seconds - until the phone starts up. If it does and isn't in fastboot you could try "Power-VolDown" to get into fastboot...
If it just doesn't react to all of this and waiting a bit (in case the battery was at 0% and needs some minimal charge) I think a replacement is the only way to go....

You could try Official Google Android Flash Tool. It's merely another method of doing what you effectively tried, but from what I've read, it's helped some folks. Sadly, others have reported that the Official Google Pixel Update and Software Repair hasn't been updated for the P6P yet.
If that doesn't help, hang in there. There are others in here who will likely have even better advice.

appreciate the links. right now, I can't even get into fastboot/bootloader mode. so neither of those tools detect the phone.
@s3axel the battery definitely isn't low. I charged it up before all this specifically so that I know it had plenty of juice (was at 93% or something).
I'm thinking maybe after letting the battery die, charging it back up will let me boot into a special boot mode
but any other ideas, please, I'm all ears

Sorta/Kinda Brick After Attempted TWRP Install - Moto G7 Play 1952-4

Ok, so I’ve run myself off the road into a deep hole and am hoping someone can help me climb out and get back onto the correct path.
I have a Motorola Moto G7 Play 1952-4 (channel). My goal is to install TWRP, and LineageOS 18.1 with GAPPS. Root is not important at the moment.
Here’s what I did:
After successfully unlocking the bootloader (thank you Motorola), I downloaded TWRP for Chanel from the TWRP.me site. My plan was to first install TWRP, then use TWRP’s install feature for LoS 18.1 and the GAPPS.
To install TWRP recovery, I followed the instructions on the TWRP site. After starting the ADB server on my Windows 10 PC and booting the phone into the stock recovery, I used “adb boot twrp-3.5.2_10-0-channel.img” to temporarily boot into TWRP recovery. I then used ADB to push TWRP.zip onto the internal SDCARD. I used TWRP’s install feature to install "twrp-installer-3.5.2_10-0-channel.zip", presumably to both slots. To the best of my memory, everything completed correctly.
BUT . . . when I powered down the phone and attempted to boot into recovery, all I got was a black screen with a small N/A in the upper left corner instead of the familiar TWRP screens. After a while, the phone booted itself into the stock U.S. Cellular Android 10 (Hell Oh - Moe Toe). I've done several power-off/power-on cycles to no avail. I am able to get to and use the stock OS.
So, like TWRP.me suggests, I figured I’d just flash it back to stock and start over. Um, nope. I can Vol-DN/Power to the bootloader menu, but “adb devices” doesn’t see the phone, preventing me from flashing anything. USB Debugging is enabled and the phone says "USB Transfer Mode: Connected". “adb devices” sees the phone while Android 10 is running, but as soon as I boot into recovery, the phone “disappears” from ADB.
The only other thing I could think to do was to use the “Rescue” function in the Lenovo/Motorola Smart Assistant. While ADB can’t see the phone, LMSC sees it just fine and I was able to rescue/reinstall the stock OS successfully, or so LMSC said. Unfortunately, LMSC doesn’t seem to fix whatever is wrong with the recovery. Interestingly, “N/A” no longer appears after Vol-DN/Power and select Recovery Mode, the black screen now says “bad key”, followed a little while later by the Android logo with a “!” in the middle of the screen and “No command” below it.
And that’s the hole I now reside in. Despite considerable searching/reading here at XDA, I'm at a total loss for what to do next.
SOOOO, I’m hoping someone can help me:
1. Fix the N/A black screen
2. Get into a mode that ADB can see
3. Properly install TWRP
Thank you in advance,
Tenaya
Did you flash the copy-partitions.zip while in TWRP?
Maybe you could borrow some ideas from the official install instructions for LineageOS.
Install LineageOS on channel | LineageOS Wiki
wiki.lineageos.org
I had some strange intermittent USB connectivity issues with a few Moto G7 Plus devices with my main laptop, but was fine connecting on a 12 year old desktop computer. So perhaps you could check to see if adb connects on another machine. Only other idea I have is to somehow flash back to stock again with fastboot.

No, I didn't know I needed to; nothing about that is mentioned by TWRP.me.
This is unknown territory for me, but your question sparks a thought for me. I wonder if 1) The stock recovery is in the "other" slot, and 2) there is some way to boot from it. That could be a way to sidestep the ADB devices problem I'm having?

At the moment, I have no way to do that. I don't think the USB connection is the culprit, ADB "sees" the phone just fine while the phone is in the stock OS, just not in recovery (EDL?.

That's my current plan, but FASTBOOT won't flash anything while ADB devices won't/can't see the phone. I'm hoping someone has a workaround of some sort for that.

Hi, first of all lets set some things straight, you are experiencing a Boot Loop, in other words a software brick. (Soft Brick) now luckily these are fairly simple to fix. Sorry to break it to you but the N/A Screen won't disappear, that used to be the Blue/Yellow Motorola Splash Screen, but since you unlocked your phone it'll only show N/A but thats okay there are tools that can help you customize this and change it later on.
Now why is it on a boot loop you may ask, well that is because there is no more operating system to load in. But worry not, try to get into your bootloader, and try to connect adb through there.

Thanks for the reply.
After I used LSMC to "rescue" the phone, it stopped displaying N/A" and began showing "Bad key". Different, but not better.

My (limited) understanding is that the only way to "get into" my bootloader was with the Vol-DN/PWR button combination. When I do that , I get the bootloader menu, but ADB doesn't/can't see the phone - nothing is listed when I run ADB devices and fastboot won't/can't flash anything.
Is there a different/better way to get into my bootloader?
Tenaya
And the adventure continues. Here's some more information.
While continuing to research this, I was wondering if there was another way to boot the phone into EDL mode and Google found some instructions at thecustomdroid.com for using ADB to boot the phone into EDL. I booted the phone to the stock OS and used the command adb reboot edl. The phone immediately went blank, followed shortly by the "bad key" message. After a while it again booted into the stock rom.
I still cannot use fastboot because it doesn't/can't see the phone.
I have also discovered that if i use VOL-UP/PWR, the phone boots directly to "bad key", followed by the stock rom. Another dead end.
I also used LMSC to "Rescue" the phone again and learned several things:
While LMSC is running, it boots the phone into the bootloader menu and begins to flash. If I do adb devices while LMSC is flashing, the phone STILL doesn't appear in the list.
LMSC definitely flashed the stock OS - when the phone rebooted, it was back to the stock OS Android start screen as if it had never been configured.
There is still no recovery and I still can't flash anything.
LMSC is somehow able to flash without a recovery present.
Anyone have any other ideas?

If "fastboot devices" can't see your device while in bootloader mode, that could be the same issue I had relating to your USB compatibility with your computer. Try to borrow someone else's computer, install "platform-tools" to see if the "fastboot devices" command works.
If that works, next see if the command "fastboot getvar all" works. You should get many lines of info come up. If it gets stuck after a couple of lines, then the symptoms are the same as what I had. I have a bunch of really old laptops and a desktop sitting around with platform-tools just for this issue. I have heard others say that plugging the phone in via a USB hub sometimes gets fastboot to connect properly, but I haven't had success yet.
OK, some progress.
I found this:
[GUIDE][TOOL] Reboot to EDL mode from FASTBOOT! No More "Test Point Method"! [kenzo]
kenzo has graciously hacked fastboot.exe to force the phone into EDL mode. Using that, the phone booted into EDL and fastboot devices can now "see" the phone. Thank you kenzo.
BTW, kenzo's fastboot-edl isn't G7 Play specific, it was originally for the Xiaomi Redme Note 3 and seems to work for some other Android phones as well.
I'm still working on getting TWRP and LoS installed, but at least fastboot can talk to the phone.

I have heard others say that plugging the phone in via a USB hub sometimes gets fastboot to connect properly

I also had no luck with a USB hub.
I haven't tried another computer yet; I'm going to see what I can accomplish with fastboot-edl.
