bricked device - Nexus 7 (2013) Q&A

Hi Everyone,
I seem to have bricked a nexus 2013 wifi. At first, it was having movie playback issues so I restored it to lollipop using factory image on the google site. I decided to get OTA up to the latest MM. So far so good. But I though about putting a custom rom to it. So I installed TWRP 3.02 for flo and flashed PN MM with the recommended GAPPS. Kernel was what came with it. It worked fine until this morning when I realized that the touchscreen was not responding. I went to BL mode and into recovery. TWRP came up but touch was not responding as well.
So, I connected the device to my PC. It now shows unrecognized device. It still charges and all that but It is now stuck on the google logo. when I go to TWRP, touch wont work. I have tried another cable, still the same. My N6 is detected without issues using the same PC and cable. Since there are no drivers, I cannot reflash anything...
Any thoughts? Or am I just lucky to have bricked it? Appreciate any inputs that will be thrown in this direction. Cheers!

Hi, N7 motherboard gets touch, USB, accelerometer and compass data via the wide silver cable which often suffers from poor contact. Please try this first. If it is still not fixed, then in fastboot mode run and post the output of the following commands:
Code:
fastboot getvar all
fastboot oem gpt-info
fastboot format cache

Thanks for the help. hmm.. i pressed that part and it booted up to PN, touch is working as well. Not sure if that fixed it but if it happens again im gonna try to press that area. however, its still not detecting the device. I see it in Device manager, it says unknown device and will not take any driver, so fastboot is not an option for me atm.

so just an update. when I was able to boot up, it will not go landscape no matter what. I downloaded check my android and it the tests for compass and sensors were not responding. I decided to open the back cover, it was fairly easy. The thing is I have not the right tools to reseat the silver flex cable and I fear I might damage it, so I tried putting folded paper on to where it connects to on both ends. Now the thing works with landscape and so far, have not experienced touch issues or no boot issues.
I still do not have access to fastboot, though, as it still isnt detected by my computer. so I may have to stick to putting stuff to it over the air. Or should I just reseat that cable? Does it just slide out?

Yes, re-seat the cable, but be careful, disconnect the internal black battery plug first and watch this video about ribbon cable connector handling.
As your main N7 problem is now resolved, we don't need the fastboot commands anymore. The USB detection issue may have something to do with the custom OS you flashed. Also note that N7 has several USB modes of operation with distinct IDs:
Code:
Qualcomm HS-USB Diagnostics 9006 - USB\VID_05C6&PID_9006
Qualcomm HS-USB Diagnostics 9008 - USB\VID_05C6&PID_9008
Android Bootloader Interface - USB\VID_18D1&PID_4EE0
Android ADB Interface - USB\VID_18D1&PID_D002
Android ADB Sideload - USB\VID_18D1&PID_D001
MTP or charging mode - USB\VID_18D1&PID_4EE1
PTP mode - USB\VID_18D1&PID_4EE5
MIDI input - USB\VID_18D1&PID_4EE8
What's the VID/PID of the non-detected device?
Does ADB work if you start TWRP?
Have you actually put your N7 in fastboot mode (when off press power+vol.dn)? Does PC detect it?
Is an OTG flash drive recognized?
Maybe Windows has a driver problem - does it work from live Linux?

I'm also having issues with the sensors not working, I re-seated the cable multiple times already and that fixes it temporarily but it keeps coming back. I even tried to use loads of tape to make sure it never comes off but it still stopped working after about a week

The next step:
disconnect the ribbon cable from both the mobo AND daughterboard
spray the cable's and PCB connectors' contacts with Electronic Cleaner
reconnect and relock

Hi,
I really appreciate the assistance. Well, here's what I found.
[*]What's the VID/PID of the non-detected device? USB\VID_0000&PID_0002\6&688A3B8&0&2
[*]Does ADB work if you start TWRP? I don't think it does. In TWRP, I still get a message on my computer that the device has failed. DM shows the device as unknown usb device (device descriptor request failed)
[*]Have you actually put your N7 in fastboot mode (when off press power+vol.dn)? Does PC detect it? no it doesnt. same error as above.
[*]Is an OTG flash drive recognized? yes it does.
[*]Maybe Windows has a driver problem - does it work from live Linux? I'm still working on this. btw the same setup works on my phones and they are detected just fine.

update:
Suddenly its now detected by my pc. I connected my usb otg. At first,. It wasnt detected so I tried the usb on my nex6 and it worked. I connected it back to the 7 and voila! No error and DM now shows it as an android device. Whew!
But I have one question, is it safe to leave the folded papers i placed on both ends of the silver connector?

Yes.
As I mentioned earlier, the silver cable also connects USB data, so if you experience USB detection problems again, then do full re-seating with clean-up.
Cheers :highfive:

Thanks again for the assistance. Hopefully, it doesn't come to that.

unbricked my google nexus 7 tablet
if anyone has bricked there nexus 7 wifi tablet.....you can now unbrick it with the skipsoft toolkit. my tablet was bricked for awhile (it was stuck on the google logo and when I tried to boot into the twrp recovery it showed the android bot with an exclamation point so I was screwed big time) so I just brought another one (different version). after awhile I gave up hope, but today I decided to unbrick it (or atleast try to). at first I was using the nexus toolkit like I did before and I was having problems with it being recognized via adb and it wouldn't flash the stock recovery.img. than I remembered that I also had the skipsoft toolkit installed on my computer and the nexus 7 tablet was also supported on that toolkit so I decided to give it a try. at first, since I had it plugged in, it wouldn't recognize that it was plugged in not realizing that I had to download all the images and recoveries it needed to be able to root it and return it to stock if necessary so I did that and when I finished installing everything it detected that my device was in fastboot mode. I flashed the stock recovery image and it booted up like it was suppose to. I'm writing this just incase so one has bricked there device and has lost all hope in fixing there mistake. I love android and recently have a lg nexus 5x that's rooted with a custom rom on android 7.0 nougat. android is awesome
who ever developed the skipsoft toolkit....your awesome and thankyou for making this possible.

Pixel XL Fastboot Works to Flash Stock ROM+TWRP. Unseen as USB in TWRP or OS

I have 3 of these devices I'd successfully flashed TWRP to months ago. I can plug the other 2 into any of my Win10 PCs and they are functional as MTP devices in TWRP or the OS. Something is wrong with this device in that fastboot works fine, yet it is not recognized as a USB device at all in Windows. No device detected ding. No yellow exclamation point in device manager. Nothing in Nirsoft's USB DevView. I was unsure if this device received an OTA update so I went ahead and flashed the latest stock firmware as of 5/24/2017
It successfully flashed albeit unusually slow (even though Nirsoft USBDevView showed it connected at USB 2.0 and not 1.1). It also successfully flashed the latest Pixel XL Marlin-3.1.0-0RC2
Even if I attempt to toggle MTP in TWRP there is no response in Windows (on any of my PCs) nor is there any response when it's booted to Android 7.1.2. Same when toggled to PTP. Same w/ USB Debugging enabled. The device charges fine. Checking OTA updates shows none available. Factory reset option in bootloader didn't help.
I'm sure I'm missing something like I somehow have the incorrect firmware loaded for something. Anyone know what specifically is responsible for the USB at the firmware level that would allow it to function in fastboot mode yet fail to detect when booted TWRP or OS???

When booted into the OS and plugged into PC, do you have a notification on the pixel that the device is connected and an option to change how to interact with the PC?

I can plug it into the PC and charge it up and receive a full charged reached message in the notification bar. Unfortunately I do not receive any other acknowledgement in the notification bar that it's connect to the PC and to toggle from "charge only" to PC MTP connection like most other phones present.
Its not recognized as a USB device at all in Windows. No device detected ding. No yellow exclamation point in device manager. Nothing in Nirsoft's USB DevView.
Yet I can flash it successfully all day long in fastboot mode ... so strange.

I know this may seem like a stupid question, but have you tried using a different cable? If the phone recognizes fastboot mode commands but not PTP or MTP, then perhaps the cable is going bad. I would blame it on your drivers but fastboot mode wouldn't work if the drivers were malfunctioning.

Same behavior with a different cable. I've also tested on USB 2.0 and USB 3.0 ports. Also different PCs. Up until today I couldn't get Windows to acknowledge anything. Today I observed Windows a couple times present "usb device not recognized. the last usb device you connected to this computer malfunctioned and windows does not recognize it."
However even after it did that once on one PC today and again on another PC today, I couldn't get Windows to present that message any subsequent times. Even when that message did appear as a system tray notification in Windows, Windows still wasn't showing the phone with a yellow exclamation point in device manager like it sometimes can for many other devices it would otherwise present such a message for. (I just speak from past experience with older PCs)

Wow...that's puzzling then. You said in your op that you factory reset using bootloader menu but have you tried flashing factory image with fastboot in bootloader? Maybe the firmware that's malfunctioning could be fixed with a factory image flash...

That's what's killing me. I can successfully factory image flash (same I've flashed on the other handsets). Yet the USB doesn't work in the OS. When this initially happened I thought for sure USB was going to work like usual in TWRP (works on the others) but it doesn't work there either.
The only other thing I can think of out of desperation is flash Pure Nexus ROM or Resurrection remix in the hopes that somehow affects a USB bit setting at the firmware level. (Mind you flashing factory nor TWRP helped).
My exotic theory is that fastboot driver has an ability to work in USB 1 mode and TWRP or OS level driver can only work in USB 2.0/3.0 mode. Even though I don't see any visual defects to the pinout on this handset I'm guessing my pins for charging and for USB 1 mode is fine whereas my pins for USB 2.0/3.0 are electrically damaged or something.

Well i guess you could try some ROM flashing and see if that works and if not, try contacting Google and see if they will honor a warranty or something. Good luck to ya!

Need a help flashing stock ROM

Hi, I got this bugger for way too big price (40 bucks for non-working piece of garbage), but I needed it because nobody helped me with reflashing original Nexus 7 I botched up while flashing (can't even get to fastboot mode).
I need to resurrect it from death. Apparently, somebody was tinkering inside, one antenne lead is broken, USB port seems replaced with very wrong one (it fits, it sits, but clearly it is not original) and the main, biggest problem is that the OS is corrupted.
All I keep getting is Google logo, can't boot into normal mode, can't boot into recovery mode. Can get to fastboot interface though. But there is one problem - the USB debugging was never activated, so when I plug it into computer in fastboot mode, all I get is "Unknown USB device (device descriptor request failed)". When I try to manually install Universal Naked Driver, it keeps *****ing about wrong driver version or not compatible hardware. What I have to do to get it working except sending it to Asus and pay 5 times the tablet's price to get it fixed?
It was going to be replacement for that botched Nexus 7, but now it seems that it will cost way more...
Have you not tried the Nexus Root Toolkit by Wugfresh? I reckon you should give it a try good luck.
Yeah, that came around my mind too, but there is one problem. USB debugging was never turned on and now when I plug in the tablet, it shows in device manager as Unknown USB device (device descriptor request failed). And because there is no working communication (it doesn't show up as tablet), I cannot ADB DEVICES it, returns me empty list.

USB debugging on/off is relevant only in ADB mode and has no impact whatsoever in fastboot mode. Please boot it in fastboot mode, connect to PC and quote USB device descriptor number from device manager.
If it is 18D1:4EE0 then you have to resolve driver issues on your PC
If it is 0000:000x then you have to fix hardware problem in your Nexus
I posted more info in this and this thread.
USB Device Tree Viewer shows it as vid_0000&pid_0002, so there is hardware problem with the tablet.
So, if I understand it correctly, it can be caused either by badly seated cable or bad USB port. Sice the one that is there is clearly changed for the wrong one, I will try to order proper one and see what will it do.
By the way, I already tried to reseat the ribbon cable, no luck there.

I Guess I Discovered a New Form of Hard Bricking on my Device???

I was running the Developer Preview Beta 2 and noticed that my device would no longer communicate correctly with my OTG usb jump drive, I tried all the normal trouble shooting techniques and nothing worked. I than tried connecting my phone to my computer and my computer would no longer connect to my device either. I didn’t think this was a big deal so I was going to just flash back to the May factory image from my computer.
This did not work, so I did a factory reset in TWRP hoping that this would clear out the issue that was stopping the phone from usb communication. It did not fix the issue. So normally in TWRP I can always plug a flash drive into the phone through the otg and explore the files, however for some reason this was still not possible, something has happened to the device where it no longer allows incoming or outgoing usb communication. The device still charges however it is no longer recognized at all by my computer nor does the device recognize usb drives. I have all the latest USB drivers and updates needed. I uninstalled and reinstalled my drivers on my computer as well. The main issue I feel like I am having here, is that the device no longer wants to communicate with usb asides from charging, this is why it is not seeing the otg storage when I plug it in while I am in TWRP.
I am at a loss, I can boot into twrp and explore the device, this is useless as i deleted all the files on the device, TWRP will not allow a usb to be found so i cannot flash anything to the device. My computer does not see the phone so i cannot fastboot anything to the device. I have tried everything, DUECS script, skipsoft, none of them have identified a device. This is further verified by running cmd and typing in adb devices, to which the response is a blank line.
How can a device be bricked, but somehow have TWRP recovery working, along with the ability to boot the device into fastboot/the bootloader (and yes the bootloader is unlocked still)? If anyone has any ideas of how I can get this thing to be recognized by my computer please let me know.

I would try a different cable as this device is very finicky; that solved my issue of the computer not recognizing the phone.
Is it possible that your device's USB port data transfer function is damaged, but the charging portion is functional, making it a weird hardware failure?
You know, like the old days when the charge port would break or wiggle loose, and sometimes it would charge and sometimes it wouldn't, depending on the angle of the cable in the mini usb port?

That would be nice if that were the problem, but unfortunalty I do not think it is. For example, when the issues first began, before I did the factory reset on the device, windows would pop up a message that said unknown device, and failure to connect. After the factory reset in TWRP the computer gave up all together in recognizing the phone. Another sign it was likely not a hardware failure was when the device was on and i was attempting to connect the otg usb to the phone it would give me some weird options. With android P the options were, allow this device to control the usb, or allow the USB to control the USB. that made no sense to me since why would i want the the USB to have any control, it couldnt do anything its not a computer its only a storage device. However, even though I had file transfer selected in developer options, it would not allow this connection. The options were all greyed out and it would not allow the pixel to have control over the usb device.
As for USB cords I have used without fail the google issued USB cord that came with the Pixel 1 xl, It has never faile me or had any issues. It is still fully functional as I was able to use it to connect my girls note 8 to my computer for file transfers and all other things my phone is not doing anymore.
I reached out to google and explained the situation to them, after i told them I was on Dev preview beta and they verified this to be true they told me this is likely a hardware failure and offered to replace the device. I am now waiting on the new device to be sent to me, however still cant accept that i cant recover the current device with an unlocked bootloader, TWRP installed, and access to fastboot/bootloader screen. I have seriously bricked phones before as in they would not even turn on and I was able to get them back up and running, this would be my first ever device I could not recover and what makes it worse is that it actually has TWRP installed and powers on and off just fine.
Sorry for the obvious question: Do you have the latest drivers? I don't have the drivers set to the whole system (Windows), so if I don't CD into my fastboot folder, I can't do anything because the system wide drivers aren't current. Don't know if that could be your issue?
I'm too lazy to fix the PATH of my drivers ¯\_(ツ)_/¯
I had an issue similar to this. I was trying to hook up a USB c to Ethernet adapter. It worked fine on April's patch but after I flashed Mays the phone wouldn't recognize it. After I plugged it in my phone rebooted and I no longer had access to developer options and it wouldn't read any usb device. Luckily I had a TWRP backup on my device. Once I flashed the backup which was only about a week old everything worked again. I haven't tried using the adapter again. I think something in the data partition got corrupted. I tried just restoring the boot and system partition and that didn't fix it. Try doing an advance wipe and formatting the data partition. That might get you back up and going.
have we even seen a bricked device yet?

I didn't think it was possible, I still dont understand how this is happening. For the other responses above, I have all the drivers up to date, and I already formatted data, wiped everything. At this point I would like to see if there is anyway to delete TWRP recovery from the device, anything, I have no OS on the device, but for some reason still have TWRP on both A and B.
I almost dont want to give the phone back to Google because I want to figure out what happened and how to fix it, its definitely not broken/bricked like you see when someone flashes the wrong files to a device, it just has no USB connection capabilities which in-turn have rendered the device useless.
When I had Samsung phones if you bricked a device to the point it doesn't even turn on correctly you could always save it still using ODIN. Its weird that the google flagship device and software doesn't have its own proprietary flash software like Samsung, LG and HTC, we just have adb/fastboot, I feel like if we did, i may be able to get this thing started again.
have you tried using something like quickboot from the playstore to be able to get to fastboot?
I had a similar thing happen a few weeks ago on oreo. PC wouldn't 'see' the phone, but it would charge very slowly.
I installed quickboot, booted to fastboot and was able to flash the factory image

I can't access the play store on the device in it's state. I do have access to fastboot. I can boot the phone to fastboot, and into TWRP, only problem is the phone doesn't communicate with the computer in either state. If the pixel had a SD card slot I would just load up a recovery but unfortunately we don't have that luxury
What cable are you using to connect to the PC? Is it USB c to USB c?

The cable is not the issue, I confirmed this by testing all my cables with the new device that I just received for my warranty exchange. I also tried my luck with Linux, after a complicated installation on my computer I was able to have Linux actually detect the device (partially) when the device was plugged in at splash screen I got nothing, at fastboot/bootloader screen nothing, but once the phone booted into TWRP it came up as AOSP device, when I attempted clicking on the AOSP device being detected by Linux an error message popped up telling me mtp or midi error, not sure for sure what one it said. Either way I couldn't connect for any transfer of information, I tried adb sideload and that failed as well.
This has been an experience for the memory books, glad that old device is gone and I'm back up and running on a working phone. No more beta testing for me, I'll be ready for Android P when they get it out of beta, I don't have the time or patience to deal with any more warranty exchanges.

Feb 2019 update kills PC usb connection

Strange issue. After applying the Feb 2019 security patch over air, my phone is no longer recognizing when it is plugged into a PC. I plug into my PC and I get a charge symbol on my battery but no pull down option to switch from charging to USB mode. Things I've tried:
1. New Cable although the wife has a Pixel 3 (standard) that works with this cable and computer just fine.
2. Different PC
3. Toggling USB debugging
4. Changing the USB setting in developer mode to transfer
5. When I plug a USB stick into the phone using the USB-C to USB-A adapter, the phone recognizes the stick and I can browse files
6. "Cleaning" the USB-C port
7. Also booted into safe mode (which I would assume should be like a factory reset) but no USB.
8. Switched between USB 3 and USB 2 ports on the PC.
It seems to me that there's a software issue with the Feb update that messed with the usb settings. I called google and they just want me to factory reset my device before they will transfer me to tech support. I'm avoiding that because I don't want to go back through the time/trouble of resetting up my phone. Any tips/tricks I've missed here?
If you have a Google variant with the BL unlocked, flash the factory image with the -w removed from the flash-all batch file. That way, you won't lose data. If you are on the Verizon variant or don't want to unlock you BL, sideload the OTA from stock recovery. See if it cleans up your issue. Also, sounds like you might have a driver issue on your PC. Easier to fix that first if it is the issue.
I have the February update over the air and I had no issues connecting to my Chromebook (crouton) via USB to pull an APK with ADB. I did have to turn USB debugging back on (not sure if I turned it off or if it was turned off from an update) and change the connection type, it was set to charging only.
More info this morning. I have an Android based car stereo that when I plugged my phone into this morning, I did get the USB drop down. So it seems to be a windows 10 problem. I have both a Surface pro 4 and a desktop running windows 10 that are fully up to date that show the same symptoms. I don't know how I'm going to sideload an update if I can't connect it to my computer.
1. What I don't understand is why the Pixel 3 would work and the Pixel 3 XL would not. Same driver set, no?
2. Also, PC with Windows 7 also has same issue.

Try putting the phone into Fastboot mode and use the command "fastboot devices" to see if it is recognized. If it is, then the problem is on the ADB side, which is part of the Android system.
If it can connect via Fastboot, it's less likely to be a driver issue. You can try "adb devices" too with the phone booted to see if it is recognizing it all. May need to toggle through the various connection modes, I believe I used PTP the last time, but not certain.
As for sideloading, you will need the phone to be recognized by either ADB or Fastboot. You can sideload an OTA update from Recovery with a locked bootloader or as @sliding_billy said you can unlock the bootloader and flash the factory image which is done via Fastboot.
I would also verify that you have the latest version of the Android SDK installed just to cover that base.

You don't need to be in file transfer mode to connect via fastboot. Check connection from there after using the combo keys to get into fastboot (power/vol down) for the factory image or one step further into recovery for sideload.
Neither Fastboot devices or ADB devices lists a device. When put in fastboot and recovery, my device manager on either computer does not register that there is a device connected.

Sounds like you have attempted everything... New cable (but rereading I don't see where you tried using a C>A cable instead of a C>C and that definitely needs tried). New computer/port/OS. Direct connect to fastboot. I think you are going to need to backup to the cloud (at least you have a functional device with internet) and factory reset the device.
P.S. I just thought about this, but do you have the current platform tools (ADB/Fastboot)? https://developer.android.com/studio/releases/platform-tools.html

Sadly I don't have a computer with a USB C port. I have been using only cables with C>A. I downloaded the latest platform tools yesterday before trying fastboot/adb. I'm waiting for a call back from Google tier 2 tech support within 72 hours. If anything comes of it, I will report back here.

[solved] Recover Data: Touchscreen doesn't respond, fastboot only, Stock Android One

Hey gals and guys,
my girlfriend dropped her Xiaomi A2 lite and no the touchscreen doesn't respond. The phone has the stock Android One and I can only access fastboot.
Code:
fastboot devices
recognizes the phone.
The recovery is the stock recovery.
Code:
adb devices
won't recognize the phone and gives me an empty line as output
I also can't access the phone via usb with my filebrowser. If I try, the phone makes a "bing"-sound and the filebrowser gives me:
Code:
unable to open MTP device
I am using archlinux and I also have a windows device available.
Is there any chance on getting pictures etc from the phone?
Any suggestions besides getting a replacement for the touchscreen?
Thank you so much.
Connecting via USB probably needs you to click something.
I'm guessing developer mode is not enabled...
If you've got a micro USB OTG cable, you could plug a mouse in.
If you boot TWRP (fastboot boot twrp-3.3.1-dees-troy.img) you should be able to get adb and usb transfers working. Don't need to install it, just boot it. Not sure if that works without unlocked bootloader.
