Hi guys. Everytime i use usb OTG, i unmounted it, i'll get a freeze n reboot afterwards. How to solve this problem? TQ..
Please provide a little more information. I'm stock-rooted, 4.2.1, cwm recovery, stickmount pro. It works perfectly. Do you unmount it by pulling down the notification bar and touching Stickmount to unmount before you unplug the cable?
Sorry.. im using smooth custom ROM, rooted,unlocked.. i did both but still freeze after i unplugged the flash drive..

I'm having the same issue myself. Stick Mount was working fine for months and then this happened. I remembered that I recently updated to PD 2.99 Beta 8. This version actually shows USB storage under your system settings. I couldn't get that to work by itself and it is probably due to the kernel I am currently using. Ill have to test a few out. So I'm thinking with the updated rom's USB support running together with Stick Mount might be causing some problems too. There's my 2 cents.

i seem to have a problem with mounting the internal storage on the phone, it doesnt ask me to mount when i plug the phone in like it normally would so i tried mounting through recovery but still cant do it through there, tried 3 different roms and all the same issue, are there any kernels with this issue? im running newest nscollab with the kernel it comes with...not sure what to do
are you running the latest recovery? can you use the storage space with apps on the phone?
I have been having the exact same problems. Nothing seems to work. Can't mount through CW and I have the most recent version. Randomly it started to work again by turning the phone off. Plugging phone into computer. Turning phone back on. It would recognize it until now. Now that doesn't work....
I am using Mac and Linux and neither one need drivers so that has nothing to do with it.
I'm screwed if I have to take the phone in for warranty work because I am rooted.
Anyone come up with something to fix this?
Or is there a way to "force it to mount?"
Its really f'in annoying

So it's showing the storage on the phone and not on the computer, correct?
Can you select to mount the USB when you plug it in?
Does the device show up in the System Profiler app in Mac OS X?

That is incorrect. It does not show up on the phone. When it shows up on the phone it mounts to the computer. It is not even recognizing it on the phone now. For awhile it was working and now its not again. Haven't done anything else to the phone.
When it doesn't show up on my phone it is not recognized by the system profiler.
Never had a problem with any other android device except on my epic 4g when I tried running the miui beta for it. But it would still mount in clockwork.
It is not the cable because I have four different cables. One of which works flawlessly on my epic. Which had a lot of problems when using the stock cable.
Is this hardware related or is it because of the rooting process?
What r some possible fixes if any?
I really would not mind going back to stock and starting over. But the only way to get back to stock is by USB. And nothing recognizes it. Adb. Fastboot. Odin (heimdall in Mac terms) nothing recognized it

okay, I had this issue when the nexus s 4g was first released and the first roms/recoveries came out. I would just start over. backup using titanium backup and flash the stock files in fastboot, then unlock again, flash the recoveries, etc.
How exactly would I revert to stock if commands from my computer in fastboot do not recognize the device?

Try es file explorer and give root access ... this was u can atleast access files from your phone...
PROBLEM SOLVED... at least for me
Found out when flashing to a stock rom (currently running MIUI) that my usb port on my phone is loose. Just have to be careful with it. Makes sense that it was randomly happening.
With MIUI it wouldn't show right away because I had it set to auto-mount. But when i flashed the stock rom. The pop-up to mount-sd would show up and go away show up and go away....
Darn.

Use this app. it requires root (assuming you have it)

You might could try the app called nexus media importer in the play store

He said he's already tried it.
Have you got SuperSU to grant super user access to devices?
As StickyMount needs superuser permissions to function.
If you don't have SuperSU, download it, configure it and then try to manually run StickyMount, it should ask you to grant it superuser permissions, do this and your good to go.
If you've already done this, I've seen people removing stickymount, clearing all the data/cache etc, delete it from superSU list and then re-install StickyMount, re-grant it superuser and you should be good to go !
I confirm loss of OTG support with 4.1.2 - I downgraded to 4.1.1. and recovered OTG support.
This is a bad update....
Stock kernel on both...rooted...using USB mass watcher with OTG but tried others on 4.1.2 to no avail...
Ehud
Mine has OTG support with stock 4.1.2, though only intermittently. I traced the problem to the OTG cable. Something is loose in the female usb head because it stops working whenever I lightly touch it and starts working again when I push the cable deeper into the plastic cover.
Maybe something similar is happening to yours.
Rooted, stock kernel, 4.1.2 OTA: I still have full OTG-usb support with Stickmount. I just now viewed some pics on a flash drive and copied a file to the external drive.

Which ROM are you using?
Rooted, stock rom, stock kernel, now 4.2.1, cwm recovery, stickmount. OTG works perfectly for read/write and streaming media.
4.2.1 , no OTG-USB!!! what's wrong
Are you rooted and using the current stickmount app? The storage media should be FAT32. Some cables may not work. Maybe try with a wireless mouse receiver.
Edit: Just saw your other thread. Sounds like you are doing the right things. Did stickmount ask for root access?
It might be your otg cable
For some users, the app appears not to work, while in fact it is the device itself or the cable not working. One OTG cable is not the other OTG cable. If you have a USB stick with a light on it, it should light up when you connect it to the Galaxy Nexus using your OTG cable. If it does not, either your cable or your Nexus is faulty. 99 out of 100 times it is going to be your cable. That the cable works fine with another device does not mean anything! Cables known to work on a one devices may not work on another device.

Yes it did .. Not sure about the. Cable but can anyone confirm that it works on 4.2.1?

OTG working perfectly for me on paranoid android 2.99 rom
I just got my Asus Nexus 7 today and i have a problem. First thing i did is connect OTG cable to it and i was suprised when keyboard didn't work. After that i rooted my tablet with motochopper script and i verifyed it to work. Since i saw most of people use StickMount i downloaded it and when i started it it did not ask for root which was weird for me. I conenneced my USB flash device to OTG cable and pressed mount but nothing happened. My USB device is formated to FAT32 primary partition. I also tried with some other USB flash devices and only thing i noticed is that on one of them light blinked but nothing happened. I also tried with some other mounters but nothing happened. I can confirm that there is new USB connection when i connect OTg cable (lsusb). I can confirm this cable works becouse i tested it with Galaxy S II and it worked. Please, help.
ROM: Stock
Bootloader not unlocked
ROOTED: Yes
BusyBox: latest & all tools symlinked
Some otg cables work with some devices, but not others. You need to make sure that your cable is compatible with the Nexus 7. Can you share the link where you bought yours from?

Stock kernel would make no difference, as it is compatible with an ext kb right out of the box.

I tried to install a new font with Font Installer, as it had worked in the past, but my phone then got stuck in a boot loop. I had already gotten rid of my backup after I found out that PA wasn't going to be updated until 4.4, so I thought there was no need for a Nandroid until then. I do not seem to have any PA ROM .zip's on my phone anymore.
A couple weeks ago, my usb port stopped working and everytime I try to plug something into the port, it begin to heat up and there is a burning smell. So I cannot transfer anything through usb.
So I made a factory reset and then wiped the system and now when I try to reboot, TWRP says "No OS Installed." When I proceed and the phone reboots, I am stuck on the screen with "Google."
Is there any way I can fix this?

First of all it is a good lesson why you always have to keep a nandroid backup.
Ia the USB on your PC is the problem? Can't you go to other PC and transfer a zip to your nexus?
I guess that USB is the only way.. You obviously can't use WiFi or bluetooth. Find a PC and do it.
Good luck.

You're right about that.
No, the usb on my N4 is the problem. Plugging any usb cable into the port doesn't work. No computer can recognize the device and the device is unable to charge through usb either.
I'm very sorry and it's painful to say but I can't think of any solution.. Maybe only to fix your USB port..

My Nexus 7 2012 wifi model is driving me nuts. :crying:
Every reboot keeps going through the same long startup "Android is starting" "optimizing app 74 of 98" etc takes ages to boot.
I have tried factory reset. Did not Work
re rooting and re writing custom recovery. Did not work.
Never ever had this problem before flashing the image on previous occasions. Only thing that has changed is the version of Nexus root tool kit.
Using nexus root toolkit v2.1.9
and factory image Android 5.1.1 LMY47V
Put me out my misery. :crying:
You can try to wipe cache/dalvik cache from custom recovery. Why insisting on LP 5.1.1, it lags a lot, with that rom Nexus 2012 is barely usable. I am on AndDiSa's Nougat 7.1.2, working very well

Thanks. You put me in the right direction. After 3 years of lag because the final firmware from google was crap. I never thought that would be the cause. All this time I thought I had a bad internet connection until now.
I now have a super fast Nougat O.S
All that's left to fix now is the external memory card which is not detected. Would you happen to know if Nougat 7.1.2 detects otg cable's or does it need fixes. I have installed the two "stickmount" files but still not working. It could be that I lost the ogt cable and using the wrong one, but I don't think so.
I had a similar problem with recognising external memory via OTG (with LP 5.1.1), but now I haven't. Besides in-built file manager, i use MiXplorer which is excellent file manager, just check enable OTG driver in settings. I have simple, no-name OTG cable from electronic shop

I had the same issue: as soon as I flashed and unrooted 5.1.1 stock, my tablet went off the rails. I guess it somehow grew intolerant of being rooted.
I flashed the Unofficial LineageOS, and now I'm as happy I can be.
I was saving for replacing my Nexus 7, which I use as an e-Reader for Kindle, Kobo and some local magazines with a specialized Android reader with a Kindle Fire, but I ended up replacing the dinged battery and using my Nexus 7

Thanks. Mixplorer much better than "es file explorer" that I had been using for many years and had become slow to load with all the added unwanted bloatware functions.
Still no luck getting my external usb recognized in android Grouper 7.1.2. Have order another cable which will hopefully get it working but am sure I am using the cable that worked fine before on my previous os.
I have the "enable otg" box ticked in Mixplorer, have installed the two stickmount files from chainfire and downloaded the additional files it required. Have used the tool "usb host diagnostics" by chainfire but it detects nothing when I insert the usb cable. The memory cards are fat32 formatted.
I was about to post a thread with the same problem! On every boot it is optimising 98 apps. I've wiped cache etc but the problem persists.
The thing is, this only started occurring when I rooted it on stock (whichever the last official version you could download from Google) . I used CF Auto root and flashed TWRP mainly because I wanted to install the Parrotmod. Is it because I rooted it on a stock OS as to why it is doing this?
By the way how's the Nougat performance on this Nexus? Does it get slow over time?

Working fantastic for me. Only had installed about a week so too early to say. I first had it installed with the BeansGapps-Mini-7.1 which gave good performance. Then I read better to use the Pico version of Gapps which to my amazement gave even better performance. No going back to Android 5.x Lollipop for me.
Don't use last version of the google stock which was 5.1.1 (LMY47V). It is crap and freezes often. I guess you could go back to kitkat 4.4.4 as Lollipop not good for Nexus 7, but I recommend Nougat with the pico Gapps judging by how well my Nexus 7 is now performing.

Still not work. Can't even tick the "USB OTG" box via the Mount option in TWRP. So hoping my new cable will fix this when it arrives.
Looks like a hardware issue, OTG table or usb port. Good luck with the new cable

New cable also not being recognized. Will try a bit of wd40, tablet does charge via the usb.
Figured out the problem. USB port will only function if I apply downward pressure on the cable where it plugs into the mini usb. Taking the circuit board out was not too difficult, so I ordered a new part.
same issue - and nougat won't install...
hi all, and merry xmess! I rooted my excessively lagging Nexus 7 (2012) yesterday with a lineage 14 build but NRT did not manage to flash it: I was informed that build would not work on my tablet, it had to have the 5.1.1 build.
So I eventually flashed that, and get the 'optimising apps' merry-go-round...
In my case it is now optimising 79 apps, even though I installed only the nano version of GAPPS plus a few of my originally installed 'essentials' from Google Play. So how is it chewing on 79 apps?
Any help appreciated!

This doesn't have anything to do with stock firmware. If I remember correctly, this is a normal android 5.0-5.1 issue and occurs with any odexed rom. Basically when android LP boots it makes all the system apps executable, (that's what those nifty odex files are for), by putting the app together with its odex file. While this makes a much faster rom when it is booted, boot time (clearly) suffers on lower end devices due to the apps being deodexed when memory is low (hence why they have to be reodexed at boot). There is an app that blocks this from happening, but due to the Nexus 7's tricky ram issue, it slows the device down. My solution? Don't run android on this device. Try other OS's, try Ubuntu, try webOS, try Sailfish OS, try anything else. There are some good android roms for the OG Nexus 7 but most of them tend to start slowing down over time. Again, take what I say with a grain of salt.
