[Q] Ubuntu touch read only [Solved] - Nexus 7 (2013) Q&A

I have installed Ubuntu touch on my flo via multirom. Everything is running great except, I cannot figure out how to access root (directory). When I try to remount root it spits out that it is write protected as read only. Does anyone know how to make root writeable? I would really like to be able to use apt-get.
I am also interested in wether or not ADB is supposed to work with Ubuntu Touch, so if either of these questions could be answered I would be gratefull. Google has been no help to me.
Reference: http://forum.xda-developers.com/showthread.php?t=2011403

I have found my answer. First off, in the updated version of TWRP for multirom, in the multirom subsettings there is a tick box for ADB access. Doing this will let you connect to your Ubuntu rom through ADB.
Once I figured that out everything was rather easy.
Code:
adb shell
cd /
cd userdata
touch .writable-image
After that I reboot my device and I was able to use apt-get again. Hope this helps someone else.

Rooting on a Mac OS

Is it possible to complete the whole process on a mac? I don't have a PC.
i found this.
http://www.droidfilez.com/Evo4GRoot.html
dont know what it is/how it works though.
proceed at your own risk.
yes, all you need to root is adb!
download the adb sdk for mac and use the terminal app in utilities to execute adb commands
after you set up the sdk execute the commands, like the examples :
./adb devices
./adb shell
./adb push
just follow the guides to root and wheerever it says to use adb use ./adb instead because your on a mac.
hope you got the jist of what im saying
i wouldnt use the above post "automated rooter" just yet... you're new to this, you should research mroe about the automated rooter and if it does what it says it does. wait till it comes up on xda?
EDIT : follow the guide that waterboy100 posted below if you want to do it without adb. i would encourage you to learn adb though as its simple and will help you learn more about rooting in the long run.
this guy should have a post up soon too

I am downloading the sdk now and I am interested in this. I have the 1st root completed and I am trying to get the second section done and I am having a hell of a time :/
you can totally do every rooting ability in Mac. I got a hackintosh and downloaded the ADB kit and just plug in the phone and ADB recognized in an instance. No need to install driver like Windows.
I just did the rull NAND unlocking with root on my Mac.
Awesome I downloaded the files and I'll try doing it today. I wanted to remove some Sprint Apps and maybe flash a ROM later one when the builds become more solid and bugs get worked out.
By the way I'm playing Pocket Empires to kill time and it's pretty cool. If I root will I have to start the game all over again?
i've done everything on my mac...works great!
I'm lost as hell. I found this thread:
http://www.androidpolice.com/2010/0...-write-permissions-to-system-incredible-next/
I did the unrevoked thing and I see this icon called SuperUser Permissions in my app list.
Am I able to proceed and fully root or do I have to re-do the root with the Toast method? This looks too complicated and by the way I tried the ./adb thing on my mac and I get errors saying "No such file or directory".
im trying to push the pcimg to sdcard and its saying access denied
Why do you guys say "Oh, I did it on my mac" without saying HOW you did it on your mac? Regular instructions dont work so you obviously did something special to make it work... I keep getting permission denied BS
Here you go dude. Step by step instructions along with the download links. I followed this to the T and it worked out find for me:

Unable to use adb commands after using ROM Manager

Hi Gentlemen,
I have noticed that after partitioning my sdcard with ROM manager I can no longer use the remount command I was able to use before using adb shell.
I am probably doing something stupid.
Can someone please guide me in the right direction if possible?
It will be greately appreciated
I wa able to figure it out, I needed to mount system while on clockwork.
The mod can delete this post if he decides.
Thanks

G-Slate root

There's no G-Slate forum yet, so this goes here.
How to root your T-Mobile G-Slate
This process works under Linux. The hard part under Windows would be mounting a file as an ext4 filesystem, but if you can do that you win.
You need:
The four files in the gslate_root.zip archive attached to this post.
To root:
Put those four files in a directory and open a terminal to there.
Shut down your G-Slate and plug it into your computer via USB.
Hold down both volume buttons and press the power button. The G-Slate will not appear to turn on, but it'll go into APX mode.
Running "lsusb" should show an entry "0955:7820 NVidia Corp."
Run the command "sudo su" to get a root shell. Running "ls" should still show the four files.
./nvflash --bl bootloader.bin --getpartitiontable ptable.txt
./nvflash -r --read 8 system-orig.img
Wait while 400 meg of data copies.
cp system-orig.img system.img
mkdir system
mount -o loop system.img system
cp su system/bin
chmod 4755 system/bin/su
cp Superuser.apk system/app
umount system
./nvflash -r --download 8 system.img
Wait while it copies back.
./nvflash -r --sync
Press the reset button under the sim cover to reboot.
There's your rooted G-Slate. Making that process "one click" is going to suck.
Troubleshooting:
You may need to install the package libstdc++6 or lib32stdc++6 to get nvflash to run.
You may need to use "sudo" on the nvflash commands.
If you want to try to make this work on Windows, the nvflash.exe binary and the APX USB drivers are are available from nvidia.com
This is unbelievable! Can't wait to give it a shot.
EDIT: For future reference, DO NOT use Virtual Box to try and root your device. There are issues getting the drivers to work properly. Lsusb will not work. The following methods have been tested and work:
1. Wubi install of Ubuntu Linux
2. VMware install of Ubuntu Linux
3. Dual-boot install of ""
4. Dedicated Linux box (duh)
And remember: If at first you don't succeed, try try again. Then visit our IRC channel.
Trying this on Windows 7 is gonna be a trip. Never workt with ext4 before.
Install Ubuntu and you can dual boot into Windows or Ubuntu. That's what I do.
Sent from my LG-V909 using XDA Premium App
This method is confirmed working. Thank you so much for the hard work Chandon. It wasn't very hard to complete on Linux. I can't believe my G-Slate is rooted!!!! Hell yes! Oh and the device is not wiped during the process either just to let everyone know!
Some More Help
Would it be possible to pull the recovery partition off now?
Why I ask. I am in a bit of a pickle. My slate will get to the first LG boot screen and then freeze. It does not even go to the boot animation. I can still get into fastboot and APX mode and it is seen by my computer.
How did i get here. While poking around in fastboot I am pretty sure i wiped they recovery partition D'OH.
I was able to complete the steps listed (for root) with out issue but still cannot get past the boot screen since this is only modifying the system partition.
I am thinking that if that could be pulled from the device i could flash it to mine and bring my slate back to life?
Am I way off on this one?
SmellyTunic -
Attached are all the reasonably small partitions that I could pull off my device with nvflash. This should be everything except /system, /cache, and /data.
I suggest backing everything up before flashing any of these, on the off chance that there's some difference between devices.
Thanks so much for this! Is there a good linux live cd(or bootable usb flash drive) someone could suggest where this could be accomplished easily? Not ready to take the plunge actually installing linux on my system yet >.>
Here you go
shinkinrui
Info and steps can be found here http://www.ubuntu.com/download
Pretty easy to set up a dual boot machine.
Chandon,
Any chance you know off hand which one of those partitions is the recovery?
I suggest doing a Wubi install [1], where Ubuntu pretends to be a Windows app (which you can then uninstall like any other app later). Alternatively you could try using VirtualBox [2], but that's less guaranteed to work.
The only reason I wouldn't do this with a Live CD is that you'd risk losing your backup of the stock /system partition when you reboot. It would also make losing power in the middle of the flash really annoying.
[1] https://wiki.ubuntu.com/WubiGuide
[2] (edit: virtual box doesn't easily see the USB device)
Thanks guys, reading about that Wubi solution looks like the simplest way to have a dual-boot system. I like it! I'll be getting my root on later tonight
i prefer Ubuntu just cause you can install it in windows then simply restart and boot into Linux or Windows. This way you don't need to worry about not having Linux again.

I'm sure that /system is 8 and the kernel is 13, but don't know about anything else. You might be able to figure it out by reading the ptable.txt file generated by the --getpartitiontable command - it's pretty clear except for the part where it uses 3 letter partition names.
Thanks. I will take a look when i get home from work.

I definitely concur.
thengkiu so much

I have no idea why I'd ever need/want to root my G Slate, I'm fairly simple in my desires for my device - but I have to say I'm delighted to see it is possible and am ever so grateful for folks who figure this stuff out because it keeps moving G Slate towards legitimacy.
Thank you!!

No kidding. Since the linux method failed miserably for me, I've decided to press forward with trying to do it on Windows. Problem is, I have yet to find any way to mount an ext4 filesystem on Windows. There are several options out there that will allow you to read ext4 filesystems on Windows, but not write. Any suggestions?
my friend will be happy to see that this is possible.

[Q] KF2 Rooted with cm11 and kitkat running

My kf2 was working fine but I ran out of room to install apps. I deleted unneeded apps still not enough room. I booted into twrp did a full wipe and now I can't side-load any roms to install. Twrp shows no OS installed. It will boot into twrp fine but nothing else. I have a fastboot cable. My computer recognizes my kf2 as an adb device but I can't seen to get anything to load. Some of the commands in KFFAID work but not all. I am trying to load cm11 and kitkat back. Any help would be appreciated.

if sideload doesnt work then just do this, put the rom you want to flash and its gapps in the folder that adb is in, and run this while booted into twrp: adb push romnamegoeshere /sdcard/
then you can install the rom from inside twrp
didn't work

Here is what happened. It said the device was not found. In the device manager it shows adb device under kindle fire.
Look on your task manager and kill every instance of adb.exe that you see and try again, I had that happen before when multiple instances were running. As long as it is in twrp then adb should work. If it continues to not work then uninstall the adb driver and if you see the MTP kindle device still there remove it as well, there might be a composite device that needs removing too, I find it a pita going between fastboot, recovery and whatever ROM os flashed if I use windows because of this, the drivers constantly have to be reinstalled when you change modes for me, hence why I avoid working with my kindle in windows and instead just use Linux. If you see any USB composite devices, check the hardware id's for a vid of 1949, if it has that then feel free to uninstall it. This may sound a bit complex, if you need more of an explanation just tell me.

My computer only recognizes the kindle as an adb device in fastboot mode. I haven't been able to use any of the adb commands on it with any luck. It says device not found. This only shows in kffaid version 4.1.87-beta.
*facepalm* you don't use adb commands with fastboot, you use fastboot commands with fastboot. When it is in twrp it should have adb access though...

I think I have a driver issue. I forgot to thank you for your help. If I could send the zip rom and gapps I could get it back to where it was. Is there anyway to start all over from the original kindle OS at this point?
Thanks you
You coukd restore it in fastboot using kffa but it seems like unnecessary work. I would boot a ubuntu 13.10 live cd/usb and just attempt it from there since there won't be any driver issues.

these commands should do the trick assuming the repos are all active in the downloadable section of the software updates control panel.
Code:
sudo apt-get update
sudo apt-get install android-tools-fastboot
and after that the fastboot command will work but keep in mind to give it superuser privis with sudo or it probably wont work, i had forgotten that recently on my own pc since i don't deal with fastboot too often. ex: sudo fastboot -i 0x1949 getvar product
I had to work all weekend. I tried to get access through ubuntu 13.10. I used the commands you provided (sudo apt-get update). This command worked fine. When I used this command (sudo apt-get install android-tools-fastboot) It said I had to enable universe. I did some research and got that working and tried to use this command again (sudo apt-get install android-tools-fastboot) then this one worked fine. Then I tried the last command with my kindle in fastboot mode flashing green light (sudo fastboot -i 0x1949 getvar product ). The message was cannot connect to otter-2 ... device. Same thing I have been getting all along.
I think when I wiped the system I cleared all the software to connect to any external device. I don't know if I can even get access to restore the original OS. If you haven't guessed by now I an a noob. I think you realized that with my adb commands with fastboot enabled. I got the impression you knew when I saw the *facepalm* comment the the beginning of you post. When my kindle is booted to twrp my computer does not recognize it. My computer will recognize as an adb device when in fastboot mode. My computer will recognize it as a kindle (with a yellow triangle in the device manager) when it is trying to boot with the white and blue logo. I don't know what to do at this point. Here is a screen shot with adb side load from twrp.
Interesting, seems that data didn't want to mount. Have you tried adb from Linux while in twrp? Just run "sudo apt-get install android-tools-adb" to install the command, if you can get adb access at least then I may be able to help fix this depending on what exactly is wrong. BTW I didn't exactly think you were a noon with that facepalm, I just see people get that misconception a lot about adb and fastboot commands. What exactly did that fastboot command report back, I was surprised it was an error when I saw otter2 in the error considering that was what that command was sort of supposed to report back.

Here is where I am. See below. Now where do I put the file in ubuntu so I can access it from the terminal window. I am running ubuntu from a live CD. I tried the push command but it says no such file or directory. I told you I was a noob!
[email protected]:~$ adb devices
List of devices attached
0123456789ABCDEF recovery
Since adb is in a system path must out it in the current directory you are CD'd into, if you left the terminal alone it should be in ~ (the home folder of the Ubuntu account) so photo the home folder and drop it in there and run "adb push filename /sdcard/"
Considering that /data doesn't want to mount and that /sdcard os technically in /data, that command might not work depending on what's going on. I reccomend seeing if you can first and if not goto the months and mount /cache if its not mounted already, and they pushing a twrp update into it to try to reflash twrp, its small enough I think it should fit into the cache, though I don't think a ROM would fit.

Um OK well the filenames are case sensitive in Linux so lookout for that. Also if it was in your home folder then it should have worked as long as you didn't CD anywhere else in the terminal first.

Problem Fixed
I fixed my problem. I had to restart my kindle into recovery mode and connect the fastboot cable to the computer and kindle before it booted into TWRP. At that point while booted into TWRP I used the push command in ebuntu terminal to sideload cm11 and gapps. After I loaded them I installed them with TWRP and rebooted. Now it is restored to where it was when I wiped it. I will not do the advanced wipe again.
adb push cm-11-20140202-NIGHTLY-otter2.zip /sdcard/
adb push gapps-kk-20131119.zip /sdcard/

Kindle fire 8.9 error updating binary in zip

OK, I had my kindle running cyanogenmod 11. I was having problems with some apps running on it, root was acting weird. Root checkers said it was rooted, but some apps that required root weren't installing right.
Fast forward, I thought perhaps I needed to flash the new version. I got into recovery to run it and flash it and this is the error I have.
So all the forums said, just wipe it then it will work. Of course now I have no OS on the thing. TWRP is fine, but I can't use the tablet.
So some other forums suggested it's either a mounting to E:\ problem or a rooting problems. I can get in to ADB, I've pushed many different roms over and they all have similar errors.
All of the Root tools I can find require you to come in the front door. TWRP fails when it goes to 'fix permission' and every time I reboot says , 'root is gone, swipe to fix' but it's not seeming to stick.
Any ideas on how to make sure I can mount the new rom and get this back up and running.
As I said, I've tried many roms, directly downloaded from CM website: Download:

I'm running TWRP 2.6.0.0 and have a binary ADB driver of 1.0.31. I can ping 4.2.2.2 so I'm pretty sure since the issue is coming from the device itself, and the way it's erroring reminds me of other permission problems I've seen in other devices that it's a root issue.
Is there a simple command line ADB tool or something that I can use to validate/set root?
Thanks!

Your TWRP version is out of date. Flash the 2.8.7.0 image from this thread, reboot into TWRP and make sure your TWRP version is now 2.8.7.0, and try flashing CM12.1 after that.

HI! thanks for that advice. I wish I could. I've tried several methods, and although I can get into ADB shell, I can't access su:
besides kindle fire first aide and other batch files, I found some manual instructions:
http://forum.xda-developers.com/showthread.php?t=2277105
Here's what it tells me to do (among many other things): I realize this is just backing up stuff that doesn't exist etc, but it's indicative of the problems without having su.
adb shell su -c "dd if=/dev/block/mmcblk0boot0 of=/sdcard/boot0block.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/boot of=/sdcard/stock-boot.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/recovery of=/sdcard/stock-recovery.img"
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/system of=/sdcard/stock-system.img"
mkdir C:\KFHD8Backup
adb pull /sdcard/stock-boot.img/ [C:\KFHD8Backup]
adb pull /sdcard/stock-recovery.img/ [C:\KFHD8Backup]
adb pull /sdcard/stock-system.img/ [C:\KFHD8Backup]
but if I go into adb shell and type any commands, like just simple su:
I get /sbin/sh: su: not found
when I do whoami: I get root
but I get a funky prompt:
~#^[[61;5R
instead of a normal # root prompt.
So I'm kind of stuck because I can't really do anything without the su, and it says I'm root. So can I adb push over the files and mount the right drives or whatever to get it to recognize su. At that point I can install twrp, but i'm sure at that point my existing twrp will work too!
I can't seem to get it into fastboot mode either. When I adb devices it says I'm in recovery, not device and in TWRP it says no OS installed. So my only functioning loader is TWRP. (or however you put that more accurately).
I feel like with adb push working, I should be able to do something to get this back, but all the tools expect you to just push a button, not do it the hard way.
So long story short, if you can point me to a thread that tells me how to update TWRP or how to push SU over with ADB or anything that would be awesome. I"m not a complete turd at this, but I think I broke it using something like kingoroot instead of just using the bin4ry while I still had the cyanogenmod working somewhat. So I'm thinking that's why i got the funky prompt, and that's why my su is gone from where it should be.
