[Q] [Help] Possible bricked Nexus 7 after 4.2 stock update - Nexus 7 Q&A, Help & Troubleshooting

Hi all,
I'm really hoping someone can help.
This morning I applied the stock Google 4.2 (JOP40C) update from Google's factory images page using the supplied flash-all.sh script. The tablet applied the update, rebooted - and then I saw an error message saying an app had crashed, I believe it was the launcher but basically ignored it, and after pressing "okay" a few times I just held the power button until the power off dialog came up and I turned the tablet off.
Now it won't turn back on. I've tried the long-press method (I've tried 30 seconds, 1 minute, whilst plugged in to the mains, whilst plugged in to USB, volume up/down buttons held and not held) but so far it's as dead as a can of spam. I gave it a two hour charge on a wall charger, still no difference.
When attempting a stock flash / debrick via fastboot, fastboot just says "waiting for device" and waits forever. That's the same on Windows and on Linux, both systems usually work fine with ADB and fastboot.
When connected via USB to my Ubuntu PC, dmesg says:
Code:
[15660.333585] usb 3-1: new high-speed USB device number 4 using xhci_hcd
[15665.328725] xhci_hcd 0000:03:00.0: Timeout while waiting for address device command

[15746.080986] usb 3-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes
When attached via USB to my Windows PC, which usually works with Android / fastboot / APX devices just fine, I see an "unknown device" appear, with the status of:
Code:
Windows has stopped this device because it has reported problems. (Code 43)
Now I'm guessing it's dead and time to call Asus, but I wanted to check first. I went to back to the PC World store I bought it from and they say because it's a month old it's not their problem (over 21 days since purchase) so it has to go back to Asus.
Can anyone give any advice? Is there a way of re-flashing the bootloader some how without the need for fastboot? Is there something like nvflash for the N7 (I've seen this mentioned before here but it didn't seem to lead anywhere). Given that I can't get it to respond to fastboot nor ADB and as the screen never comes on I guess it's dead, but I'd welcome any hints before I call Asus - thanks in advance! :good:

Problem: Bootloader won't connect via USB, won't load from MicroSD

Hi,
From the bootloader I am unable to connect via USB or to flash from MicroSD.
I am running SPL-2.08.000 8G XE
I have magldr version 1.11 installed with a cyaogen mod 7 running on top of that.
On the PC, I am running Windows 7 x64.
When I run the bootloader (pwr on + hold vol dn) it says serial at the bottom and when I connect it to the Win7 machine one of three things happens.
1) Nothing.
2) On the Windows Desktop I get a message that "USB Device not Recognized"
3) On the phone, I get a white only bottom (no Serial or USB message)
This happens with both the routine to "disable drivers signature" by pressing F8, and without doing that.
I have also removed Windows Mobile Device Center 6.1 and the drv update. It still will not load. I have tried the AS drivers for Win7x64 and it says "no driver for this device found in this folder".
One possible solution was to flash the rom, via the MicroSD card, by renaming a .nbh to LEOIMG.nbh. However, I have tried several roms (1.66 roms, windows 6.5 roms, magldr 1.12 and magldr 1.13 nbhs) yet, the phone goes grey and says "Loading..." but nothing happens.
I am genuinely stuck.
I've been through a million forums and I can't seem to find a solution to my problem. As you can see I have tried several different solutions that I have found but none have worked.
My aim is to update magldr to ver 1.13 and load a newer rom.
Thank you,
P
"USB Device not Recognized"
This usually happens when cable is faulty or the jack.
It also happens when the phone is unresponsive.

It charges... how else can I test the cable? Or the jack on the phone?
//edit: I have a spare cable and have tested it. It is not the cable. I have also cleaned the jack. A wiggle of the jack does not yeild any difference.
I went into Linux on my machine and ran
[email protected]:~$ dmesg | tail

What I suppose is really unusual is that this has happened AND I'm unable to flash via MicroSD.

ok,
Are you using front USB port? if yes then try different port at back.
Because its strange on some motherboards that it stop reading properly from front usb's :-S this happened to me with my panasonic camera which wasn't readable at front but did work on back.

[Q] Any way to recover files from S4 with dead screen?

I have an old Canadian Bell based Galaxy s4, with a dead screen. I'd like to try to get files off it, but did not enable usb debugging mode prior to the screen breaking.
Is there any way to access the file system on the phone in this situation? I've done a bit of looking around and can see that I should be able to access it via adb if I have usb debugging turned on, but debugging isn't on in this case.
I have usb connected the phone to my fedora machine and can see via dmesg that it does get detected. I can hear the thing start up, but beyond that I can't see anything else.
Googling around it sounds like I should be able to load a recover kernel, with debugging turned on if I use the right process, but I can't find enough into to get me going.
dmesg output is below just in case it helps...

Any help is much appreciated!
If you can get a custom recovery on you can use adb without use debugging on. I assume you have an i337m. Try this with twrp http://galaxys4root.com/clockworkmodtwrp-recoveries/
Sent from my Nexus 9 using XDA Free mobile app
If you have a custom recovery plug it up to hdmi thru HML and use the TV for the screen. Hopefully the touchscreen still works. This worked for mine. No lcd but the digitizer was still good.

[Z00LD] USB Connection not working (MTP, PTP, ADB), but USB OTG works

Hello,
It's been a while since I have been facing the problem described in the title. Only now I've managed to get some time to investigate the issue. I'm using LineageOS 15.1.
I was using Lineage 14.1 before, and I had the following issues:
USB OTG was not working
MTP, PTP (and the rest) ALSO not working
After I flashed Android 8.1, USB OTG started working, but ADB, MTP and PTP still did not work. I realized it could be a hardware problem. So I tried connecting with several different USB Cables: did not work. It is also not a driver issue, since I tested in multiple computers (with Linux and Windows);
Then, I bought a new charging board (the one that also has the phone's mic.) and exchanged the old one. That did not help at all.
I was messing around with ADB over network and I happened to make the phone get recognized - about 3 times - using the setprop command:
setprop sys.usb.config adb,mtp,ptp
The problem, after the OS (Ubuntu 16.04) managed to recognize the phone, was that as soon as I unplugged the cable and then plugged it back in, the phone stopped being recognized again. Running dmesg on my PC returned this:
[15548.910595] usb 1-2: new full-speed USB device number 12 using xhci_hcd
[15549.730614] usb 1-2: device descriptor read/64, error -71
Click to expand...
Click to collapse
I also got a device not accepting address error (on dmesg), which I forgot to copy
When I boot into the bootloader (Fastboot Mode), the dmesg output is:
Bus 001 Device 008: ID 0b05:4daf ASUSTek Computer, Inc. Transformer Pad Infinity TF700 (Fastboot)

I appreciate your help. Any extra information needed, please ask.
Thank you.
I have the same problem with the rom lineage-14.1 and 15.1

Will not boot after forced update through adb

A while ago now I tried to update the stock rom with the update that it downloaded ota and repeatedly failed to install.
This in turn ended with the phone not giving any signs of life at all.
Put in uUSB cable to charge, no reaction on display and no charge led.
hold power button, no reaction etc...
I have opened it up, disconnected the battery, waited a while then reconnected with no change.
If I remember correctly (I bought a huawei p20 lite since I needed a working phone and have been using it since), I had unlocked the bootloader and had twrp (spelled wrong?).
Is it a paper weight now or is there any way to get any life into it again?
I do have JTAG programmers if I can find the correct places to connect the leads on the board and also soldering experience on very small things (not bga ic's).

Hello.
In order to install stock updates you needed stock recovery, it does not work with TWRP recovery.
I'm not a technician but I think, I repeat I think, you f***ed the phone.
Use your tester or take your phone to the service point, maybe the motherboard is gone ..
P.S.: Have you tried first with another cable / charger, both ?
Regards

Can't get any sign of life from it at all.
In linux, if you connect a usb device you see a message with a command called dmesg that gives info about the connected device, there is no reaction when i connect it.
Example when connecting my p20 lite:

If it's detecting the device your fine. Go here, https://flash.android.com/build/7005429?target=flame-user&signed. and re-flash the firmware and you will be good to go.
I reflashed boot.img to slots A and B, and system.img to system. Now I get "Failed to load/verify boot image". Still no adb but fast boot is now working

You need to re-flash everything. It should do all the work for you. Maybe you flashed the wrong boot.img? Here is the main page for all devices. https://developers.google.com/android/images Select your device, you can choose flash and it will do it all for you or you can download the image, extract it all to your adb folder, double click flash-all and it should flash everything on its own.
