[Q] Undo ubuntu? - Nexus 7 Q&A, Help & Troubleshooting

hey guys, im bored and was thinking of installing ubuntu on my nexus but before i did it i was wondering how do you get back to android. im pretty sure your recovery stays, so if i just boot back into twrp can i just restore a backup or flash a rom and then its all good or do you have to do a complete reset, unlock etc.
also i saw zedo's video start this but didn't mention how sucessful it was. can you backup ubuntu via twrp and restore it whenever? this isn't really important to me but its been in the back of my mind.
thanks in advance guys

This doesn't exactly answer your question, but I think you should give this a try: MultiROM
It lets you easily install Ubuntu alongside your current Android installation, and it's easy to uninstall too. I've been switching back and forth between Android and Ubuntu for a day now and have encountered zero issues.

cool! ill look into it. if anyone has answers to my original question tho that would be awesome to

I'm mostly guessing here, but couldn't you just use on of the Nexus Toolkits to revert to stock and flash recovery? Whichever recovery Ubuntu installs (why would it even install another one, I don't know), there must always be fastboot or flash option?

I installed it the other day. You lose everything. You could keep your nandroid on your PC. Or just install multi rom like mentioned above.

[Q] Non rooted Gingerbread Stock - Custom Revery Which one ??

Hi,
My warranty has just run out on my Nexus One so I've decided to unlock the bootloader.
My Aim is to get from stock non rooted Gingerbread to rooted Gingerbread with busybox, SU, and ultimately being able to boot into ubunto in chroot, I've been reading up on all this for a few days now but just need a small amount of help with Recovery, Gingerbread ROM choice, and the order that thing should be done, by someone who's done this before.
I take it the first thing is to install SDK and get The USB Driver working on PC, its running XP by the way.
Then I unlock the bootloader, !HELP! to do this do I enter hboot or fastboot, before connecting the phone to the PC? I have to copy 3 files somewhere and use ADB and run command for **** OEM unlock, can't remember the exact command, (I've got instructions for this) and then agree to void my warranty etc.
I then find and download the correct custom recovery image and copy this into the tools folder of the SDK. And install (got instructions for this to).
!HELP!
Which custom recovery image should I use? and which Rooted Gingerbread ROM is most popular ?
After installing the custom Recovery can I just flash a custom ROM? I've seen something about SU.zip mentioned, is this necessary?
If I can just flash a custom ROM, I do this by downloading and copying the custom ROM of choice to the root of my SD card. Start phone in recovery mode and install from SD? I then install the google add ons .zip (if required) using the same method.
Sorry for such a long post and so many questions but I can find all the information for what I'd like to achieve but not in one place and nowhere in any chronological order.
Any advice appreciated .
Please read the Wiki, "Root" guides, "Unlock bootloader and install custom ROM" thread. Execute until the point of installing custom ROM.
Look in "Recovery" section for recoveries, install the latest Amon_RA.

Thanks everyone, but this looks like the one for me, going to unlock bootloader now install custom recovery and flash su.zip.
I'll post back with how I went on. Wish me look

Flash this as well, otherwise you will lose your custom recovery...

Good show with unlocking the bootloader, it's the best way.
However... looking at your flag, you're in the UK... this means your phone is still in warranty, as we get 24 months.

My understanding was 12 months but, your probably right. I've unlocked the bootloader now and fortunately my N1 is in good condition, funtioning correctly ( well at least for now, I'll have to cross that bridge if and when I get to it )
Getting on to custom recovery, I realised something wasn't quite right after my first attempt. I installed custom recovery but without su.zip on my SD card. I managed after rebooting my PC to complete the custom recovery with su.zip on the SD card and was successful in that I've got SU on my N1. However I am quite sure I do need to fix something with the recovery, can someone explain what method or how I do this now. I've unlocked the bootloader, I am rooted with gingerbread but with a dodgy recovery.
Or do I do exactly the same as I did with su.zip and push recovery from ADB and flash from SD card, making sure that fix-recovery.zip is indeed on the SD card.
Hope this makes sence?
Any help appreciated.
After I unlocked my n1 I used rom manager for everything else, first flashing clockwork mod, then selecting a stable cm 7 build and flashing that, since then I've done everything through recovery, flashing custom kernels and nightlie builds, I'm currently using cm7 rc4 highly recommend rover theme too!

I've got ROM Manager installed and if I want to try anything it tells me I have to flash clockwork mod recovery, I was unsure if It was safe to do this after using a completely different recovery image to get where I am now.
Sorry for being such a paranoid newbie, but we all got to start somewhere ;-)

I think CM7 rc4 is next, I do want to get Linux up and running though, even if it's in a virtual environment (chroot). and deffinately would like to check some nice themes out, I've not even looked at themes yet, I suppose it's quite easy after unlocking bootloader, installing custom recovery then flashing su.zip though. But still any pointers where to start my quest wouldn't go a miss ;-)
Recovery
its safe to let rom manager flash clockwork,ive done it
I heared about amonRA but it seemed like clockworkmod was more commonly used so I went for that, but yeah it's fine to flash a new recovery, just remember that whilst it's rare things can go wrong, it's YOUR fault not anyone's here regardless of the advice you may get here if your phone gets bricked or screwed up.
That said I'm still new to this but I'm learning as I'm going, just remember to backup your phone using rom manager before doing anything major so that you can always recover your phone/rom.
I started out hacking my nokia 5800 so was keen to have a go with the android platform.

[Q] TWRP -- why?

I'm new at Android (have jailbroken Iphones before) so these questions are probably basic.... I have a KF that has been rooted, but until ICS is stable, and maybe not even until it gets USB host mode (if ever), I will probably not be changing ROMs. I am mostly happy with the current state of the KF, but have been reading forums. I see that TWRP can save you later on if you mess something up, so that brings up quesitons. BTW, I followed the tutorial on androidpolice to get the root done. S, on to the Qs...
1) Should I install TWRP on my device if I don't plan to put on any ROMs?
2) How can TWRP help you?
3) Any concerns with installing TWRP at this point, when everything is working?
TWRP is working just fine. It allows you to make backups of the current setup in case you break things.
Sent from my Kindle Fire (CM7) using xda premium
Absolutely reccomended. ESPECIALLY if you are new. It alwows easy backups and recoveries in case you jack something up.
1 thing ur iphone never couod do, make a true backup of ur current state. it saves u down the road. i have a backup of completely stock and i make one of cm7 every now n than just incase

Thanks for all the advice. I did install TWRP last night. Simple to do, made a backup, and all is well. Thanks for all the advice.

Question about CWM vs TWRP

I am real new to the KindleFire community but so far loving my Kfire. I see in slot of posts they say to use TWRP to install or update a ROM. Since I have CWM installed can I use it instead are they interchangeable for installing files?
Hope that make sense.
Thanks
Rod
most people are taking about twrp because it was the first recovery for the kf
cwm is quite new for the kf
you can use both to install roms ...
Cwm is able to be updated by current developers. Twrp looks cool, but just needs to be updated. If someone updates the reboot wrappers it'd be a winner. But I do like and prefer cwm

Is there or link or how-to to swtich from TWRP to CWM? Does CWM have all the features as TWRP? I have been using TWRP since I rooted the KF, have used it to back up, flash new roms to try out, flash back to my backup. CWM does all this, just dosn't have the nice CWM interface?

The easiest way is to use THIS method, just be sure to unzip the file on your Kindle rather than on a computer or it may not work correctly. The only difference I've noticed between CWM and TWRP is that CWM does not compress the backup so the file is a lot bigger, my backups used to be in the low 500mb range and now they are in the low 800's.
Any particular reason to migrate to CWM? I have TWRP from the first day ant it doing a job very well. So, did CWM have any new features?

Development should be the main reason imo I think the interface looks way better. I got annoyed by the flickering backlight with twrp. It does all the same things, but cwm looks better. Plus before I switched, twrp wouldn't flash roms or gapps all the time, it would get stuck and I would have to reboot

For me there was not a reason to use TWRP as I have been using CWM for the last several years on smartphones and was more comfortable with it. I also read several articles where people had issues with TWRP so with as much problems as I was having trying to root my kindle because of USB driver I wanted to stick with something I know. So I thought it best to stick with and old friend I was used too. Not saying one is better than the other I just like CWM better for me and think it gives me more options to perform operations on my phone and kindle.

How have the pros and cons changed with the intro of TWRP 2.1? I am currently using CWM touch but prefer the TWRP interface, but don't want to sacrifice any features.

different versions of CWM touch?
I just switched from CWM touch (DooMLorD) v1.0 Final to v5.0.2.7-kf1.5 I was wondering what the differences are? I tried the Change UI color feature, but it doesn't seem to work, just stays red. is there something I'm missing? and what else was changed?
its just cleaned up. not sure why it wont change colors, works fine on my device I tested all the colors when I posted the screen shots.

[VIDEO] Idiot's Guide - How to Install CM10 on the HP Touchpad

This is my FINAL VERSION of my Idiots Guide for the HP Touchpad. Now that a stable enough version of CM10 is available, I finally created a guide for you.
Here are links to the files you will need:
CM10 03/04/2012 Build
GAPPS 10/11/2012
ACMEInstaller3
Moboot 3.8
Anything else that you might need, you'll find on http://www.reverendkyle.com
Thanks for the video. It came just in time as I just purchased a used TP that had an older version of android ICS already on it and I wanted to upgrade but seeing as how this is the first device I have sort of inherited already rooted, it is hard to just jump in and know everything that I would have learned from the beginning like i did with my previous phones.
Anyways, I did everything you said except I used the newest AOKP rom. But my tp is still booting to the older version of android that I had on it. Any ideas? Feel free to pm me if you prefer that.

If the AOKP ROM is using a unique uImage file, then you may see two different entries on your moboot screen for two different Android builds.
What does your moboot menu have in it?
Maybe your install failed. Try downloading and flashing it again. If you're trying AOKP JB, you should wipe both /data and dalvik cache to avoid a boot loop!
If using AcmeInstaller3 remember to rename the ROM with ”update-” at the beginning so that it looks like update-AOKPJB_UnOfficial.zip

I believe it was the "update-" thing that was keeping it from updating. I followed another video tutorial which provided files that had the "update" in front of them and it worked.
I haven't tried yet but now that it worked will the regular method of wiping and flashing through recovery work? (Like, if I want to try out different JB Roms) Are there any files that need to be in a particular place for the recovery method to work? I tried that method first and it would never take, would always revert back to the original version. Don't know if, because I just jumped in and haven't been here from the beginning, I am just missing a necessary step that is hardly even talked about anymore.
Love your work Rev! Thank you again for everything that you do!
Update went like clockwork, unfortunately I can't seem to get the camera to work (not a terrible loss, but I was sorta excited to see it actually working with this release).

I can attest to the improved battery life on this cm10 build. Amazingly, it holds battery life when it's sleeping now.
Thank you so much for taking the time in making the video for us. Your instructions are easy to follow, hard for anyone to mess up.
(The hosting site for the files is not working, not sure if you were aware)
Hi, I have CM9 running on my TP. With the latest release, the camera works great. But before updating it to CM10, I'd like to know about the issues currently in this build.
Thanks.

Don't go for external mirrors unless some recognized developer suggests them. Best will be to wait for goo.im to come up again, being a prime site, it won't be down for long.
The goo servers do appear to go down on occasion. They always come back up a bit later.
Problem with installing GAPPS using ACMEInstaller3
Excellent tutorial for an idiot like me. Thanks for again for the guide! Question:
I followed the instructions step by step and was able to get CM10 installed successfully. However, I wasn't able to get GAPPS installed using this method. From researching I understand sometimes there is a problem installing GAPPS through ACMEInstaller3 and one can simply get GAPPS installed through CWM Recovery. However, I would like to use/have TWRP instead so is there a way to get GAPPS installed properly through ACMEInstaller3 and then I can install TWRP through GooManager?
Alternatively, is there a way to install GAPPS without using CWM Recovery?
Or, I guess I can install CWM Recovery first, then install TWRP Recovery, then remove CWM Recovery while keeping TWRP and not go back to the stock Recovery? I tried to search the forums and wasn't able to find instructions on removing CWM Recovery WHILE still keeping CM10 and not go back to the Stock recovery.
Any help would be much appreciated. Thanks in advance for your help.
@reverendkjr - appreciate your videos. they're awesome. definitely helped me (and several other friends) many times and saved a ton of time. super easy to follow.
Yes you can install TWRP normally, flash gapps in CWM then install goomanager app, open and click the 3 dot menu and install custom recovery script then it will install it
Now using a root file manager go to the directory called boot and delete uimage.cwm.img (this is from memory but still should be correct

[Q] -Updating, So simple a 4th grade could do it?

Hey guys so I am coming over from using a jailbroken iphone to now using a rooted nexus 4, which i found harder to do than jb an iphone (yeah ik i'm that bad)
And so here I am today I have my nexus 4 on the 4.2.2 update, no custom rom or kernel or anything, just super user access. And I really wanna start doing more such as the 4.3 update, custom roms and tweaks and such but before then I wanna make sure I got my back up down.
I rooted using the "Nexus 4 toolkit" and by choosing the one option does all option, which installed the twrp backup I believe.
Now I am super noob to android and i've already read the pinned guides for introduction to android and rooting but the rooting one was too complicated for me.
So I'm asking for easy 4th grade instruction for anyone who has the patience and time to help me accomplish these things
1. get onto 4.3
2. have backups for future use
3. be able to have a custom rom installed.
4. not end up with a new paper weight (like I did before when I first tried rooting, yes I'm that bad)
plz and thank you very much,
1. Download the Nexus 4 Toolkit which I'm assuming you already have since you rooted your phone.
2. Install a custom recovery, I recommend TWRP for ease of use and because its awesome D).
3. Download the 4.3 flashable zip from the Android Development forum and put it on your external storage.
4. Turn off your phone.
5. Hold down the power + vol down button til you get a screen which says start, and a bunch of scary looking things
6. Use the volume keys to scroll down to Recovery Mode
7. Click the power button
8. Once you're in TWRP, click Backup
9. Click start
10. It'll take a while, but once its finished, go back to the start screen of TWRP and click Install
11. Click wipe, then yes
12. Find the zip file of the 4.3 flashable you downloaded.
13. Click it
14. Wait a bit, and you have successfully installed Android 4.3!
Additional Info:
Regarding wanting to flash a custom ROM, do the same process you just did except with a custom rom zip rather than stock android.
If you ever want to restore, wipe then go to restore and select the backup you'd like to restore from
I hope this helped!

Pretty good. I do believe they already have twrp. So just power off. Or download quick reboot app. Or ROM manager to reboot recovery if you Dont want to hold power and volume down till you get to fast boot. Or boot loader. But its all easy. With twrp you'll see you swype to engage. First thing when you get into your recovery is just click backup. Follow prompts. Rename or leave as date. I name mine virgin flash. Then back out to twrp opening again. Then wipe data factory reset wipe cache and dalvick cache. Then most cases no need to wipe system unless changing base. In this case of 4.3 I would. And returning I would. So just reboot once your backed up. So you can go download all your ****.
Gooim. App fave. Play store you'll find it. Then ROM toolbox. Then titanium backup. Then Franco kernel app. Then system tuner or system panel. Then kernel tweaking apps. All are up to you and optional. If your looking for something worthy to flash I like these.
Carbon. Liquid , and jelly beer. Also miui is the "Different ui" as most others will look identical. The ones I named can have themes in the chooser downloaded. Gives android its ui overhaul. Just enjoy ...

OP:
Do NOT use toolkits. Take the time to learn how to do things manually. It will serve you so much better in the future than just pressing a button as you'll actually KNOW what's going on and how to fix any potential issues.
To everyone recommending the use of toolkits, shame on you
Thanks for the input everyone gonna go down the list and try the instructions you guys have given and come back and tell you how it goes

As you mentioned about nexus 4 toolkit just use it to relock the boot loader and then do a normal reboot
Now go to setting>>about phone>>system update there you will see that 4.3 update is available just do it now you should be in 4.3
Now follow this guide for rooting and stuff http://forum.xda-developers.com/showthread.php?t=2384824
by following the guide u will be able to get root access in 4.3 and can be able to install a custom recovery
Using custom recovery u can flash a custom ROM NOTE:- FOLLOW THE INSTURCTION GIVEN BY THE DEVELOPER OF THE ROM IN THE THREAD
ITS SO SIMPLE THSN USING A CRAPPY IPHONE
