[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Hello everyone ,

I think I have just bricked my nexus 9 , it started when I installed the dirty unicorn rom, but without thinking I did not perform a factory reset before in recovery and now my nexus 9 will not boot at all. When I hold the power button the google logo appears for a couple of seconds and turns off quickly. I also tried fasboot , and I eventually got it to appear but it turned off after 1-2 seconds. I then tried to use nexus root toolkit to flash the factory image, but since I cant acces fastboot it wont find my device. Am I out of options, or is there something else I can do , or should I send it in for repair. Any help would be appreciated, thanks.

Update:

anyone please help , edit:: I tried everything I could to turn on the nexus 9 and when I plugged in the nexus 9 to the wall and held power + up button , it turns on and says Fastboot AC, however whenever I select fastboot it shows it for a second and turns off. I tried plugging it into the wall and Fastboot AC but when I unplug it to my computer it just turns off and from there I cant do anything and it does not turn on at all.

Is there perhaps someway I can flash the bootloader without the screen on or anything like the nexus root utility that fixes bricked bootloaders?
[Nexus 9 Q&A, Help & Troubleshooting] Hiro Nakamura:
Did you flash the custom rom via twrp? Do you still have the twrp recovery?

If yes try to boot into twrp recovery and connect to your pc.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Yes, I did flash the custom rom in twrp , however I cannot boot into twrp recovery or even into fastboot or the bootloader. My nexus 9 will not even turn on unless is connected to the wall outlet and then when I press the power + volume button it shows Fastboot ac however when I select the bootloader or anything else it just turns off. When I connected it to my pc, my nexus 9 does not turn on at all and is not even recongnized
[Nexus 9 Q&A, Help & Troubleshooting] peterk-1:
Can you find a pc with a USB charging port or a hub with a charging port? A USB charging port will be able to deliver 2A along with the USB connection. You may also find a USB3 port may also deliver sufficient power - the official spec says 900mA but I think that is the minimum requirement.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I tried using 3 different pc's , one with a usb charging port , and the nexus 9 was still not able to turn on, even when holding power + volume up or any other configuration. I tried different usb cables and still no luck. Is there someway that I can access it without fastboot or adb? I know on the nexus 7 forum, there is one click factory restore dead or alive , but I dont think there is anything like that for the nexus 9.
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
Can you take a picture of this?

I dont think you are bricked....
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I will try to take of a picture of it connected to the wall charger , it says fastboot ac , thank you for all your help everyone, I dont know what to do as I cant access fastboot or the bootloader
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
SO after it says fastboot, what happens? It just reboots?
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
No, I can access fastboot ac , however when I select hboot or anything else it just turns off.
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
All you need is fastboot. From there you should be able to flash boot.img and system.img

commands are....

fastboot flash boot boot.img

fastboot flash system system.img

Then I would run fastboot format userdata

Of course you need to get these image files from the factory image site here: https://developers.google.com/android/nexus/images

LMK
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I really want to do this , however my nexus 9 does not turn on when connected to any pc's , It will only turn on when connected to the wall charger. I have tried different usb cables and different computers and still no luck. I also tried nexus root toolkit however it doesnt recognize the nexus 9 as it needs fastboot which I cannot access.
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
Hmmm

How long have you left it plugged into wall charger?
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I tried leaving it in overnight becuase I thought that the battery might of been low, but still nothing and I dont know what else to do right now?
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
Ahhh, Ok. Thats what I was getting at.

You may have to RMA the device. Tell them nothing of root and ROM and just give the function failures you discussed here.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I dont think I can RMA the device becuase I purchased the nexus 9 from an ebay seller and I contacted him and he said returns are only valid for two weeks and I have already had the device for other two months now. Should I just sell it or can I somehow return the device to google even though I did not buy it through the play store?
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Just for reference , here is a picture of the nexus 9 in fastboot ac connected to the wall charger

http://imgur.com/coUY7qS

If I select hboot it turns off ,and if I try to plug it into a PC it just quickly shuts down and will not turn back on
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
I would still try to RMA back to HTC.

The most they can say is No.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Ok thanks for you help , I will try to contact HTC for a RMA

Edit: I just called HTC and described my situation and they said they would not be able to return it or RMA the device because it was bought from an ebay seller and they are not responsible. Is there anything else I can do?
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
Good luck to you!
[Nexus 9 Q&A, Help & Troubleshooting] Hiro Nakamura:
You can try to contact google. Maybe they will exchange it.
[Nexus 9 Q&A, Help & Troubleshooting] peterk-1:
The only suggestions I can make are:

Try and find a PC with a USB "charging" socket. I know some asus m/b's have them and also HP computers - the usb port is marked with the "forked" usb logo and a "lightning strike" . If you want to see why I say this have a look at the log shown in http://xdaforums.com/showthread.php?t=1059180 that shows charging being negotiated down to 500mA when a device is connected to a PC - this current may not be enough to to drive the device when the cpu activity increases.

If you are certain HTC will not support the device then I'd remove the back and check that the battery connection looks ok and check the battery voltage. I would guess that there is one IC that controls battery discharge/charge and USB connections - it may require a table in the rom to set up how it works. Besides the tear down photos on the web the FCC have now released the Nexus 9 internal photos (52 in a pdf) that in some areas are superior ( like you can see the fabled LED!!!) https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=2376485 The nexus 9 exhibits page is at https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=354162&fcc_id=NM80P82100
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I will try to install Asus ai charger and hopefully I can get fastboot to appear , I'll report back soon
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I still couldn't get it to turn on to fastboot , is there any way I can increase the voltage of a USB cable so that the nexus thinks its charging from the wall adapter , because I think if I can do that then I would be able to flash a factory image.
[Nexus 9 Q&A, Help & Troubleshooting] jd1639:
You'd need to flash a custom kernel with fastboot to increase the amperage. Which you can't do in your situation.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
So is there anything else I can do ?
[Nexus 9 Q&A, Help & Troubleshooting] jd1639:
I've read the thread and sorry, I don't know what to suggest. It sounds like a hardware issue, maybe bad usb port? I don't think flashing the factory image would help. But I don't know what the issue really is.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Yeah I think its probably a hardware issue , I will try to contact google about this , hopefully I will be able to RMA it. Before I do , I will try using differnt pc's and usb cables
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
UPDATE

I was actually able to turn on my nexus 9 and get to fastboot by using a multi hub usb cable that plugs into an outlet and usb , I then quickly started up nexus root toolit and proceeded to Flash Stock , Nexus root toolkit succesfully detected the device , however when It started to flash there was an error: Maybe a bootloader issue?

[Nexus 9 Q&A, Help & Troubleshooting] peterk-1:
Is the quoted output from nexus root toolkit ? If so I'd try a command line step by step install (Google fastboot flash recovery) or follow the flashing instructions at https://developers.google.com/android/nexus/images
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Yeah this was the log from nexus root utility, I'll try flashing the image using fastboot right now , hopefully this will work
[Nexus 9 Q&A, Help & Troubleshooting] Hiro Nakamura:
If you are able to connect to fastboot please try to flash all the images using fastboot commands. Remember to extract all the archives in the factory pack.
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Nope :crying:, still doesnt work , I tried to manually flash the images using the fastboot commands , and it recognizes the nexus 9 but I get an error involving something with the bootloader , I also tried extracting the acrives to a folder as you recommended but it still didnt flash.:crying:
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Hi everyone, great news!! I was able to flash the factory image onto my nexus 9 and it booted succesfully. If you were wondering how I did this, I went through so many usb cables until I looked next to my tv and saw my ps4 controller charging next to my tv. Then I realized the ps4 contollers also used micro usb cables , so I figured as a one last shot I would try that, and somehow it worked! Although after I booted up the nexus 9, I began to notice something strange. In order to turn on the nexus 9 at all you have to hold the top right of the tablet near the camera and power button in order for it to stay on. The tablet was even 100 % charged yet when I let go of the grip on it , it instantly turned off. I am now hopeful this is a hardware fix that can easily be repaired. I want to thank everyone so much for helping me out, I was literally going to mail it out today and you guys helped me out so much! :D
[Nexus 9 Q&A, Help & Troubleshooting] peterk-1:
hypothesis

I wonder if your problem stems from the CMOS backup battery. Having spent 15mins searching

I think

tablets have some form of silver oxide button cell to retain settings. I can find no pictures/mention of them in the Nexus 9 but I can find pictures of a "top right molding" of three curved prongs in a circle (to hold the cell?) and piece of copper mesh that could be folded into the "circle" as one contact. Anybody know any more?
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Interesting idea, is there anyway that I might be able to rest the CMOS backup or something. Thanks for the help!

Maybe I could somehow possibly open up the tablet and reset it or something?
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
I'm thinking of opening up the nexus 9 and try to see if any cables or connecters are loose. I saw a guide on ifixit, has anyone opened up the nexus 9 or know how hard it is to open the back cover.

https://www.ifixit.com/Teardown/Nexus+9+Teardown/31425
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Anyone know if I could just take my nexus 9 to an electronic repair shop or something and ask them if any cables or connectors are loose and see if they can fix it?
[Nexus 9 Q&A, Help & Troubleshooting] Scott:
Good to hear! Sounds like you got bad connection. I think if you take it to a well vetted shop they could fix it!

Let us know!
[Nexus 9 Q&A, Help & Troubleshooting] spartacus279:
Thanks for all your help, I definitely think its a connection problem now and will send it to a repair shop this weekend . Thanks again for all your support and advice!

And use ODIN (3.07) to upgrade:

And be sure that you pick the correct JB FW according to your Phone (GT-I8160 or GT-I8160P or GT-I8160L).

[AT&T HTC One (M8)] Wombat Pete:
Successfully rooted, busybox installed, all good so far. Now I'd like to move to the latest Viper.

The first real problem: I can't figure out my firmware version. When I run “fastboot getvar all”, the info starts with:

version: 0.5

version-bootloader: 3.19.0.0000

version-baseband: 4.0.U606061@41216A

version-cpld: None

version-microp: None

version-main:

version-misc: PVT SHIP S-ON

...

THAT IS, no main version information.

I'm new at this, though learning. TWO THINGS I don't quite understand: (i) I saw a recommendation for reverting to the previous recovery... that means just going to the Fastboot menu and hitting recovery? And then would I have to go through the reboot process again to get where I am now? AND (ii) The VIPER page describes the process, which involves flashing a stock backup and a stock recovery and THEN TWRP - I'd love to understand what that's for, why it's necessary before flashing the new ROM.

Not sure how to proceed with without knowing the firmware number. I *DID* determine that hboot 1.55 means 3.xx.xxx.x, which seems to be the case here (the "version-bootloader" line).

I *could* go for S-off, but I'm not sure I need to or even want to.

Soooo.... not sure. IN the phone's OS it says:

Android version: 4.4.4

HTC Sense version: 6.0

Software number: 3.42.502.1

HTC SDK API level: 6.25

Kernel bversion: 3.4.0-g931e842

and@ABM102 #1

SMT PREEMPT

Build number: 3.42.502.1 CL 441323 release-keys

I thought those numbers (3.42.502.1) were supposed to be clear to the firmware number. Which is consistent with "hboot 1.55 means 3.xx.xxx.x". BUT ...Viper's presumption of "1.54" is throwing me off.

Not ready to proceed, I think, until I figure it out. Any and all help will be appreciated!

So please try to stick to one thread next time. I'll notify the mods to close this or merge it.

---------- Post added at 10:58 AM ---------- Previous post was at 10:50 AM ----------

i) That does not revert anything. All you do by selecting RECOVERY in bootloader, is to boot into recovery.

You revert to a previous recovery by flashing recovery. One method is to connect your phone to your computer. Put the recovery.img in your fastboot folder on your computer, and use command prompt on your computer to flash with command:

fastboot flash recovery recovery.img

ii) Can't tell what webpage you are talking about, so hard to answer that.

1.55 is not a valid hboot number. Hboot numbers for this device are 3.16 to 3.19.

1.55 looks like a software number (although not a stock AT&T software, that I am aware).

I have an English Atom and have just moved to Beijing, however i have noticed that i get some kind of configuration menu and then a "SIM ToolKit" menu pop up everytime i soft reset. Also the phone service seems to lock up at random and without me knowing i am un contactable as if i were "out of service area". I'm using China Mobile post paid SIM card and have run the Autoconfiguration program that comes with hte Atom. Does anyone have any ideas on how to correct the problems that i'm having? Also the battery does not last as long as it did a few days ago before i arrived, i suspect that the phone is always searching for the net work....maybe?

Please could any other Atom users in China give me some advise.

Jstbuyin, I have the ENglish ROM versions from the O2 site, is that what you need or do you have the ROM but just can't install it on to your Atom?

[G3 Q&A, Help & Troubleshooting] :
I am in urgent need of help! I am running a BUMP'ed TWRP 2.8 and successfully flashed a Jasmine 5.0 custom ROM over my stock 4.4.2 10b. I managed to boot and setup the phone but for some reason I was unable to copy files to my phone while connected to my laptop through USB but was getting the error that I do no have permission to copy files so I thought going into recovery and running fix permissions would fix it. For some reason this ended up getting me stuck at the verizon logo so I restored a NAND backup of my stock 4.4.2 but now I can't even reach the verizon logo. I am still able to access recovery but I cannot access download mode. I don't have any flashable ROMs on my internal memory either. It appears I am still able to transfer some files to my phone but it doesn't work with any big files.

Stuff I have access to:

TWRP 2.8 Recovery

Old 4.4.2 NAND backup

Problem:

Can't even reach verizon logo on boot. Can't transfer large files. NAND Backup does not work.

SOLVED: I managed to solve this problem. I was able to transfer a rom zip that was <250mb which allowed me to flash it from TWRP and regain normal access to my phone. Leaving this here for anyone who encounters this problem.

I think I have the back camera working but the front one isn't I have replaced the WI-FI wire twice, I cant get kies to do an update even using 3. I tried flashing it with odin it said it passed but yet nothing.

I was able to get my gs3 working and now the s4 well i'm frustrated. Is there anyone willing to work with me and be willing to walk me through this. He loves the phone and I don't want to have to buy a new one while i'm in nursing school.

Then maybe we can work on my phone.. nothing wrong with it. would just like to know more about it. I have the g900a (galaxy s5).
