Root without pc? - Nexus 9 Q&A, Help & Troubleshooting

This device is EOL I realize but I would like to root it. Problem is I can't get any pc's to even acknowledge it is plugged in. Can I get this thing rooted again without ADB???
My bootloader is unlocked from when I first got the device.
EDIT: So it was the USB port that was bad. Ordered a daughter board from E-Bay and now I have working ADB. I'm going to leave this thread open in case someone does figure out a way to get root without adb...

If you can't get the drivers set up, try Wug's NRT toolkit. He has a walk-through on setting up/removing/reinstalling drivers. You don't need ADB to root, but you do need to boot into a custom recovery to install a root program (I use SuperSu). You can boot a recovery via CMD from fastboot as long as the recovery is in your adb/fastboot data folder.
FWIW, NRT can do all.

I'm really thinking it is my connector. Sometimes it doesn't even charge. I guess I could try to boot one of my pc's into a live Linux distro. I never had issues when I ran Arch. Actually I could try it on my server. It is an Odroid XU4 though but it runs Arch... Thanks.

Cables are most often the cause.

Linux doesn't recognize it either. I assume it is the port/cable. The original cable is long gone but I have many brand new Anker and other brands but none work for connecting... Guess I'm screwed. Really wanted root because I'm having issues with battery drain again and the screen not coming on. I wanted to get a custom kernel running... Oh well.

I use off-brand cable exclusively. Have you tried uninstalling all Android USB connections then allowing an auto re-install? I've had to do that with my N9 at times. A few times, the driver showed up in device hardware but nothing further (connection). I right-clicked and updated driver-just went through the process with no new driver just basically re-install. Once, it was the cable but all others worked.

I tried removing everything. It never even acknowledges it is even plugged in. I also tried on 1 brand new Windows system. Same deal. I did a live boot of Linux and nothing. I tried on my Odroid and nothing. I'm not new to this and have many PC's and other devices but none work.
Only thing I noticed is under developer options it comes up as ptp or mtp but if I try changing it I will always say charging no matter what I pick.... So I never even get a USB permission dialog...

As this isn't new territory, you know some cables don't have pin config for data transfer.
Are you able to get recognition of your device with ADB devices command?--recognized but unauthorized?
[C:\Program Files (x86)\Android\sdk\platform-tools>adb devices

Yup... And I'm doing it again now. This time both in Android then from the bootloader (pwr+dn).
Also apparently when I flash stock back on this a year ago for my son to use I never flashed the recovery image, or not correctly because there is no recovery at all. Just hboot... When I select recovery I get the dead Android..

I altered my previous response. Andy lying on his back is the stock recovery portal. You have to hold power button then push/release vol+. It can be tricky, but pretty sure that's the sequence. I'll flash stock recovery to double check if needed.

Doh! I'm so spoiled with rooted devices and twrp I forget you have to jump through hoops to get into some recoveries... So, I did the Android reset, Hboot reset and stock recovery hard reset. And no changes. Still only charges. Oh, well. Thanks again.

My USB started acting up on mine too. Watching a movie with a USB otg and it just stopped. I then discovered the only way for it to work was to jiggle it then hold it in a certain angle. I'm guessing something is loose. I haven't opened her up yet. I'd like to grab a new USB port for mine. Is it soldered to the daughterboard? Seems like changing the daughterboard will be easier.

I looked it up and saw it. I noticed the rear camera was attached. Thanks for the info. I changed the screen on my n7 2013, but never thought to change the port on this one. D'oh.

Got the daughter board from China. About 25 minutes to install (I'm getting real good at taking this device apart now...lol). Powered up and connected to my Windows machine. And... It is recognized now! Can't believe I fought so long thinking it was a driver/windows issue.
After taking it out I can see why it would wear out/break. Cheap plastic and it has such a large opening on the outside my son probably tried all the time to plug it in wrong...
@ritchea thanks for your help!

I did nothing but super glad you were able to fix it!...and share it with the community.

I ordered one from the link you provided. Coming from China so I hope it doesn't take too long. Can't wait. The port is waaaay to big, too much room to jiggle around. Hope this fixed my problem too.

This may sound silly, but happens to me a lot, try "jiggeling" cable were it plugs into phone. Seriously, sometimes its just not connecting. I gave this advice to many and it does work. No idea why.

Maybe not entirely related.. But i had pageonce locked to only work on my device. Have flashed hundreds of times with no issue. Until aokpm4.

Try navigating to the USB device in Device Manager and uninstalling the drivers. Then disconnect/reconnect it, sometimes this clears up issues.

I finally remembered that i have two laptops in the house and grabbed them and tried to get it hooked up to one of those...no dice. I'm thinking possibly something wrong with the data pins on the usb connector of my phone.
I'm paranoid about flashing anything because if something goes wrong I wouldn't be able to odin it and start over again...
I guess i just need to relax and enjoy the phone the way it is until may...then go buy something brand new and flash the hell out of that...

I had cleaned the pins with rubbing alcohol, a bit of felt and a toothpick (too small for a qtip) no dice.
Then yesterday evening i plugged into the computer to charge rather than walking to the other room to get my charger and i heard the Da dum of it recognizing my phone...it installed it and up pops the device...
I think my phone is like a crazy girlfriend...she is mean as hell to you all the time then when you get ready to dump her she decides to be nice and make you feel guilty you though about ditching her.

Help please! Unique problem!!!

I am trying to flash my vibrant to stock, but my laptop says usb unrecognized.This causes Odin not to detect my vibrant in download mode. I have downloaded all drivers including nexus drivers, but still same error usb unrecognized. I have then start on switching data cables including the stock data cables but the errors remain the same. I have tried on different computers and different windows, nothing working its the same errors on all computers. I have messed up by formatting everything in the Vibrant, now it boot loops to Vibrant logo. I can get into download mode normal but I cant get into CWM or any recovery mode, its probably because I have formatted the whole phone. When the phone is off, I plugged in the micro USB to the phone from the laptop, all it shows is the white lines that are in circler motions and then freezes. Weird my laptop still detects it as a USB unrecognized. As the phone is plugged in to the laptop I try taking the battery out and my phone is still on with the frozen screen of those white lines in circler Motions. Can anyone help me, or at least explain to me what the problem may be? My thoughts is that it may be a hardware problem. If so can anyone provide me some schematics on the USB portion? I hope we can bring some light on this problem. Giving it to T-Mobile is not an option. I have dealt with many problems and solved it, but this is one problem that keeps me stomp in my own tracks.
You can give a man a fish and he will eat for a day, but if you teach a man to fish, he will be able to eat for a lifetime!
Ok, so I am in a similar situation as yourself. I bought another Vibrant that was stuck on the bootloader screen. I gets into DL mode just fine, however Odin doesn't recognize it. I have uninstalled, reinstalled the drivers, used Nexus S and GNex drivers, 4 cords and 3ports and still no joy. My daily driver Vibe is like a mid-town flasher and is seen all over the place. So this leads me to believe that it is not driver/SW related but rather HW realted for me.
I think that my next step is to clean the USB ports on the phone and see if that works. If not, then I'll have to probably crack her open and clean there. I have another laptop that is using WinXP, so I might give that a try since nothing Samsung has ever been installed on it.
Keep me up to date with your findings and I will do the same with mine. Clearly I am not a noob but now this is just making me mad. Why one phone works/is seen and not the other. Common denomitator has to be HW.

I agree with you, it may be a HW issue. I have tried connecting other phones to my laptop and it reads it just fine, but for my vibrant no success. Im gonna go ahead and actally open it up and check on some componets, i have a feeling that it may have burnt one of the componets due to over charge. Ill get back with you on my findings. Keep me updated on your progress.
Before you open her up, have you tried cleaning the metal contacts inside the USB on the phone? I am at work not, so I can't try anything, but I would check that before opening. Might just need to be cleaned.

yes i've tried. I used a Q-tip and some alcohol, still same problems.
Update: Nothing!! How about you?
I have tried un/reinstalling the drivers, Odin v1.8, 1.3 and 1.0, about 4-5 cables and all 3 ports. I have cleaned the USB with alcohol and at this point am at a slight loss. The phone boots into DLmode and charges fine, so I don't think it is a faulty USB port. I cannot get into any recovery or ROM boot. All I have is DLmode and the GB bl screen. No kernel or ROM splash.
Gasp! I'm in a similar boat guys. My phone charges fine, and all my drivers are working and up to date...I can get into DL mode and all that jazz...phone even boots up and works! (fortunately)...but no dice on it being recognized by my or any computer. Glancing into the port, it looks like there may be some corrosion on the left hand side of the port, or some sort of damage...can't really tell without a proper magnifying glass. but it does look damaged or at least irregular. I've been reading around, and cleaning sounds like a potential solution...I've no idea how you guys are cleaning with giant q-tips lol but hopefully I can figure that one out also and give it a whirl xD But in the mean time, I sure hope somebody can come to the rescue
I don't know if this can help you guys, but this is how i hard bricked my vibrant few months ago. I get into download mode trying to get back to stock from ICS and my computer didn't recognize my phone....after a couple of hours my phone was completely dead and after a few days of research i brought it back to life using the unbrickable mod. What i'm thinking now is to use the Unbrickable Resurrector but you will need Linux...it always worked for me but i'm not sure if you need the unbrickable mod already applied. However i think if you have Linux installed you can have a try. Here is the link for the unbrickable resurrector http://forum.xda-developers.com/showthread.php?p=17135277#post17135277

[Q] I777 No longer able to mounted to PC...

My I777 has been acting up lately, and now I'm out of options and wondering what my next move should be.
For several days when I'd connect the phone to the PC via USB, it started saying "this device can perform faster when on a USB 2.0 port..." - which, my ports ARE 2.0.. transfers were taking forever. Now, anytime I plug it in it simply says "USB Device not recognized" - I've tried the OEM cable, the plethora of other cables, 4 different PC's... *ALL* have the same result.
My concern is with a custom ROM on it and no way to get any PC to recognize the phone to get it back to root - how should I proceed from here for warranty purposes? I've only had it since March - just wondering what's gonna happen at this point - or is this even fixable? All the threads I've seen say it needs replaced... but with no way to unroot, etc., I'm just unsure how this is gonna go.
Thanks for any advice.

You can always use Mobile Odin to flash back to stock since your on a custom ROM.

Absolutely NOT.
This is a situation that's been coming over a period of time, starting with the inability to see it as a USB 2.0 device when initially plugged in, and now has deteriorated to the point that it can't even be seen.

Yeah, I sure did - nothing. Even in recovery, it won't "mount" usb there either.
Samsung's have a crappy USB port. It fails sometimes. You have a hard time charging at all?
But like I stated above, even without a computer connection you can get Mobile Odin and flash back to stock, as long as your rooted.
I'm having this same issue. I just got the phone earlier this week and I am unable to get bit connected to my pc to root or Odin. I have installed and uninstalled Kies multiple times on two different computers, tries different ports, and checked if the cable worked by using another phone (PC recognized without an issue). I get the USB not recognized or the 2.0 USB message. If I enable debugging, I can connect regularly and transfer files through windows explorer. But if I use USB debugging off, then nothing will work. I've tried using odin and it will just get stuck at setup connection or cache.img and then I'd have to pull the device. I've tries updating through Kies when it shows the USB 2.0 message but once the S2 hits download mode then the computer stops recognizing it. I have also tried installing the i777 drovers on the Samsung website and its still a no go. Does anyone know how to fix this? Its not rooted so mobile Odin won't help me now.

It is the OEM cable that came with my Samsung Infuse. It worked with the T989 3 days ago and it's not working with my i777. Its strange because I tried it with my infuse again and I am able to Odin just fine. Could it really be an issue with my USB or will it be a PCB issue? I would rather or not disassemble my phone if it is a PCB issue. Should be able to do a warranty exchange though.

I hate to break it to you brother but it's damn near impossible to determine what the actual culprit could be, your best best is to try each and every single different thing I've listed. The end result being changing the PCB which one, isn't that hard, and two, is very cheap the only problem is waiting for the board to come in the mail.

Its strange because when I enable USB debugging, I can get a "USB connection" on the phone and data transfers fine. But when I turn it off, I get a "MTP connection" and sometimes it'll connect (5% of the time) and allow me to transfer data. But when lies tries to update when that mtp connection is active, it'll hang when the phone goes into download mode. Did you have this same issue?

I f you're able to transfer files via mass storage with USB debugging enabled then you can (most likely) rule out hardware failure on your phone.
If anything this sounds like a driver issue on the cpmputer. Are you running windows? If so remove and reinstall the drivers for your phone.
Still think its hardware.
I can connect 1/100 of the times I'm plugged into a computer. Its not a driver issue because my girlfriend has an i777 as well and no problems for her connecting at all.
Its not ROM related because I have this problem with all ROMs.

Does that apply to ums as well? From his description he can connect in ums just fine. Its only mtp that's giving him problems. In his case, with the problem only being in one connection mode, it leads me to think drivers. In your case, tested against another s2 I'd say hardware.
Just tried using a Motorola cable and a third PC and my chances of connection increased to about 15-20%. Kies and Odin failed on me a few times just like I had described before. But eventually Odin was able to flash okay. Finally on ICS on my i777! I think I'll stay on stock since I'd rather not go USB and PC hunting to flash stock if anything goes wrong.

Help!! Not charging or connecting to pc

Ok so last night I transferred some files with otg cable. Unmounted and then went to put it on charger and it does not recognize the charger. It did charge after I powered it down. But when the phone is on it doesn't recognize anything plugged into the usb port. Anyone have any suggestions? And if not how do I run a ruu or something to get back to stock for warranty without a connection to pc?

Quick update. I am on 3.09.401.1 firmware and a 2.24.401.8 based rom. Not sure if that has anything to do with it but it will charge in recovery mode but not booted up. So seems like a firmware/software issue. Is there any way to flash firmware without using usb to pc? Because it won't recognize the usb at all.

Weird problem. Not sure if it will work but you can try "flashify" from the play store to flash firmware, etc without usb. Keep us posted on your results.
Also see if you can access it through bootloader. You might be able to RUU. Alternatively, factory reset and install ROM in recovery. Or try side adb in recovery..

I'm currently using the same firmware ROM base combination as you with no issues. Are you using the charger that came with your phone, have you replaced the usb cable to make sure it isn't faulty?

I am going to look into flashify. That sounds interesting. I have tried getting the thing to pick up the usb in hboot. But no luck so far.

I have tried three different HTC branded charger/cable combinations. With no luck while booted up. I charged to 100% while shut off.
I have been running this combo for a week or something. Ever since the firmware hit the forums. And had no issues until two nights ago when this first started giving me grief... so I don't know what has caused it.
I also posted this over in the international forums and there's a guy over there with the same issue.

well i am downloading a stock backup and i have a stock recovery not sure how to get them both to work... because i have to flash the stock rom with twrp and then how do i get the stock recovery flashed with a stock rom.... i will figure it out. anyway my plan is to try to take an ota and have that change the firmware and then i will know if i have a hardware issue or a software issue.
Lol. Now I'm not sure what to do. I reverted back to stock rom and recovery and then realized the touch drivers I have aren't compatible.... But I am booted up and plugged into the pc and it is charging but not coming up on the pc as a device. I don't know if debug mode is on because I am stuck at the first setup screen... Ahh I can't seem to catch a break here...

Press the power button until the power options open. Tap and hold POWER OFF on the screen and the phone should ask if you'd like to boot into safe mode but if your touch panel is not working for you this is not going to work.

Correct. I have totally screwed myself I think. I think I basically at this current time have a fairly lightweight brick that lights up. I have no touch capabilities at all and nothing recognized when plugged into PC. I have tried plugging into a windows 8 and also a Ubuntu machine with no dice in fast boot or adb....

I dont think it is prob with some ROM. I used HTC One with stock rom (official stock by HTC) and after three months my phone stopped charging and also stop USB connection. I googled it and it was universal prob and also HTC knows about that.

Unless the OTA adapter screwed up the USB connector pins for data but not power, then you should be able to recover. However like stated there has been a few reports of failed USB connectors.
Does there seem like there is any damage to the usb pins in the connector on the phone?
Did you make sure to have the HTC device drivers installed on your PC before trying ADB. Do you have a Windows 7 PC to try?

So far I have tried on win8 winxp and Ubuntu.on the windows pcs the drivers were definitely installed. No dice on any of them. I am thinking the connector must be messed up. I can't see anything obvious looking at it but the fact that on three pcs one of them running Linux didn't find the phone but will charge it is pretty definitive. I don't have the money to pay for repairs due to having "tampered" with the phone(even though it doesn't say that) it is an AT&T phone with s-off and unlocked and a 1.55 hboot and has a inverted splash screen. Pretty obvious...

If you boot the phone into the bootloader without the cable attached it should come up and say fastboot. When you attach the USB cable does the display on the phone change to fastboot USB or stay only fastboot?

Yep, then it seems the pinouts on the USB connector have been damaged. Bummer.
On the plus side consider this: AT&T will probably still give you device exchange without charging you a fee. First, they mostly don't care about users modding their phones. Secondly there are so many exchange requests coming into them for the One, that all the defective units will just be sent back to HTC directly by AT&T and at that point HTC is not going to bother to go back to AT&T and say listen this list of devices were modified. If they did, that would create a backlog on work for AT&T to match the records to owners and then contacting them and trying to prove that the user did this so far removed from the exchange that it doesn't make business sense to them.
I have seen AT&T users report that they have sent in devices that were extremely modified and obvious, but AT&T proceeded with the exchange anyway because they would rather keep you as a happy customer than spending time trying to prove what you did was the only cause of the failure. Users have even sent back total bricks that they created by doing something stupid and AT&T still replaced the device without question.
When you modded the phone, that basically ended AT&T's obligation to help you with any service/software related issues, but the modding did not void the hardware warranty and it seems your device has a hardware issue that was unlikely caused by the software modifications.
The key in your case would be to do the defective device exchange via phone/mail and not via the walk in device service center.
If you don't want to do this because of the possible risk of flagging by them, then I may be willing to buy your bricked device if you are not going to do anything with it. PM if interested.

Revert to stock without pc

My N9 seems to have an issue with it's port as it can charge but I cannot get a pc to recognize it via adb or fastboot. All my other devices work fine on that pc. I don't even get the prompt to choose what mode to use when hooked to the PC nor does my PC recognize anything is connected. Anyway I'm running Slimrom currently but am ready to get rid of this tablet. Is there a way to revert to stock without having pc access? I know some HTC devices used to be able to flash a rom by putting it in the root folder and renaming the file something specific (model number) and then boot into bootloader. Does the N9 have that? I couldn't find any info so I'm assuming not. I have TWRP/Magisk so I could just sell/pass it on rooted running a rom too. Just thought stock would be better.

Have you tried different USB cables and/or different USB ports on your PC? I've had problems in the past myself, with fastboot/ADB connections, and changing the cable or port has sometimes resolved such issues - might be worth a shot, if you haven't already tried it.

...only works for 'true' OEM HTC devices, and whilst the Nexus 9 is manufactured by HTC, it's ostensibly a Google device, built by HTC under license from Google. And only Google make factory stock images for it...

The method you refer to, was applicable on my old HTC One M8, and apparently it works for other OEM HTC devices too, but with the Nexus 9 - a Google device - there are no such factory stock images that can be 'placed on the root' for the bootloader to auto-flash.
There is only one way of reflashing the N9 back to factory stock, and that's via fastboot (or with toolkits that use fastboot).
The only other possible way, and I suspect it to be fairly unlikely you'll be able to do... is if you have TWRP installed as your Custom Recovery, and a previously created Nandroid (bare-bones) backup of factory stock stored somewhere on the internal storage of your N9. And then it'd be a relatively simple matter of performing a Nandroid restore. But, as I say, I very much doubt you'll likely have a Nandroid backup floating around somewhere on the device, given the size of such things.
Other than that, I can only suggest you tinker around with different cables/ports, and see if you can get a response from your PC, or maybe even try another PC, if you have access to one.
Hope this helps, and best of luck

Wow long reply! Thanks for that. I've tried various cables and pcs (2). I have a handful of android devices and my N9 is the only one I can't get to work anymore. I might dig around and try a couple more cables just to be sure. It used to work a year or so ago on this same PC (my work laptop). It was temperamental then as I couldn't touch it at all or it'd disconnect. I kind of figured the HTC autoflash method (I had a EVO, M8, and M10) wouldn't work on it since I couldn't find anything when searching but thought I'd ask since I knew it was made by HTC. I'll likely wipe in TWRP and put one of the available ROMs on it with root and sell/give to one of my somewhat android capable friends. Thanks!

You can get a new usb daughterboard for like $10 us on eBay. It took me about 15-20 minutes to change, and I've never done it before. Couple screws and ribbon cables.
If that's your issue. Pretty easy. Daughterboard has the USB port on it.

Thanks I read about the camera and how it likes to stick to the back. I ended up getting a cheap Fire tablet (HD 8") just to have something but would be nice to be able to wipe this thing and see if I can get it running ok. Currently on Slim it freezes and needs to be rebooted frequently.

You certainly do have to be careful with the camera assembly, when removing the back.
Around 3 years ago, I removed the back of my Nexus 9, and not being aware of the camera 'sticking-in-the-hole' problem, I accidently ripped the camera assembly wires/connector from its socket. No real damage was caused, but reconnecting it would have required the removal of a circuit board in order to access the socket and reconnect it. In the end I decided it was more trouble than it was worth, so I've been running my N9 since then, without a working/connected camera. It's not something I've missed to be honest, but yeah... caution is required when removing the back.

I don't think I've ever used my N9 camera either. Regardless I'll take my time
Indeed. Once you've gone around all of the edges (I used my fingernail) to prise/detach the back, I would suggest some light finger pressure on the camera to 'pop' it out of its hole, before lifting the back away.
