I think CWM is not working well with 4.2.1. I would try TWRP as custom recovery, but be very (as in VERY) sure to install the TWRP version meant for your bootloader. In General section you can find a very good how-to written by pjc21, which also list which bootloader and TWRP versions match. The guide is here: http://forum.xda-developers.com/showthread.php?t=2195883
Use that and don't forget to thank pjc21.
Hey guys,
I was looking for a tutorial and a description about what is a recovery.img and if there is always the need to root any Android or Smartphone (even if it comes with Ubuntu mobile OS) to install a custom ROM.
My second question is about the Super User Apps:
I always see tutorials in which, after flashing the recovery.img they say we need to install a, i.e., CWM_SuperSU_xxx.zip. I do not know why to do that if I have my phone rooted and all I need to do is to boot it and go to the Play Store and install the latest SuperSU app by ChainFire, i.e.
All these questions have a single porpuse: To know what I am doing, because I do not like to perform tasks as an robot. I have a brain that loves to know and learn and be aware of what its doing.
Thank you very much for your help. Maybe you could point me to the documents I need to read to now all these questions.
By the way:
I rooted a year ago my HTC One-V and installed a Custom ROM before and It was working perfect until somebody stolen it from me.
My device now is a Samsung Galaxy GT-i9300. I am from Perú, and my Service Provider is Claro.
I use Ubuntu 14.04 and 12.04 and I have installed Heindall from the Ubuntu repositories. Until now I just read tutorials of how to root my phone, but I do not want to perform tasks without knowing what are them for.
So I want to wait before rooting my GT-i9300 until I know what I am really doing with my phone.
Thank you in advance!
Regarding Rooting, Please see [Q] What is rooting? Particularly #7
When it comes to Recovery, See XDA Wiki. Also See XDA University for Android Flashing Guide.
If your Device comes with Linux, then you should not use Android Rooting programs unless advised to do so. Weather Device Recovery works with Linux or not depends on Case by case basis.
In case of additional questions, please post in Android General
My device is a very popular one, a GS3 GT-i9300. It is an Android phone.
My PC, where I am going to connect my phone to root it that has Ubuntu Linux 14.04 and 12.04 installed.
Maybe you miss understood what I wrote.

So if I want to use CWM Recovery, then I can look for the latest version? Or there is a special version for my phone. Afaik it is exactly like my PC when I install a dual boot with Windows. The bootloader (maybe Grub2) is like the Samnsung bootloader and Recovery and my Android are like Ubuntu and Windows dual booting. Is that right?
And hence I do not need a special CWM Recovery for my phone, it should be a simple recovery.img installer but versions differs in features and installed programs. Is that correct? And I just can look for the latest one.
Mauricio Mora
Thank you very much @Perseus71
Your links are very useful for my purpose.
Mauricio Mora
So...
In simple words, it is like my PC.
I inicially have a single OS, Android. Maybe a Recovery but installed by the manufacturer.
Then if I install a Custom Recovery, it is like creating a dual boot: Android and Recovery.
Then if I install a ROM it is like removing a Linux distribution in my PC and installing a new one.
Recovery gives me some tools like backup my personal settings and data and even my apps.
In those terms, there should be ways to install dual boot Android and Ubuntu Touch? Or which ever ROMs in dual boot?
Mauricio Mora
If you want to install CWM, please visit [RECOVERY] ClockworkMod Touch 6.0.3.2 for GT-I9300
Mind you that is for GSM Phone only.
Yes Bootloader = Grub but Linux/ubuntu do not have a concept of Recovery in traditional android sense. In that wany Grub does do the job of a recovery. You may want to google for "What is Android Recovery ?"
If you still have continued questions, please post them in Galaxy S III General forum.

I was trying to update this Nexus S, used to be mine but gave it away to someone, now is back and I was trying to update the whole thing, recovery, Os, yet I can't find a proper way to update the recovery and also I have Win8...when I got this phone rooted I had a Win7 machine, life was great, now with Win8 some things seem far from easy.
So I wonder if any kind soul could assist me as to lend me a hand about updating TWRP 2.3 to 2.7 so I can install a fresh rom, i have tried TWRP manager (useless as it can't find the proper device), Flashify is useless also as it can't find the img file and only shows TWRP 2.1 (why the fk do I need 2.1 when I have 2.3 ?), and Rashr is no good (it simple doesn't do anything at all... )
Any help is welcome.

Thanks so much fo the Zip, is way easier to just have this done via TWRP/ZIP, than trying to install drivers and so on, it becomes a pain when one thing fails and then u have to start downloading files drivers and more.
Now I'll just start checking roms!

I have a guide on how to root nexus s in the nexus s development section..Go through it . If you have a rooted Nexus S then skip to contect showing how to flash a custom recovery using Fastboot in my guide go through it and Enjoy..
Happy Flashing.
Good Luck

Just got this same Tab for my son & have been looking around for the best ways to root. It's actually a nice little tablet. For $65 I'm quite impressed.
Couple questions for you if I may.
-Does this download have any prerequisite downloads, surveys or ads before it's installed on my PC? You know, junk & not just the program.
-Which super user app is installed?
Kingo root comes with all the files you need with no surveys or bloatware. It installs its own super user program but I deleted it wit ha system app remover and installed super su from the play store. If you can, after you root your tablet can you pull the stock lenovo launcherHD and upload it to here. I deleted mine and you need it to change the lock screen wallpaper.
hI guys!
Good to see topic about our tab 2. Small question - any1 of you got lolipop update already? Week ago Lenovo said it's ready... I have so annoying touch bug and hope update gonna fix this.
The update is not out yet but lenovo said late summer so I would think it would come out sometime in august. Once it comes out can someone try kingo root on it, I'm not updating if I can't get root.

Lolipop is out, but not in every region yet. Sadly, not in mine too (Poland).

Well I tired to get a recovery on the tablet but failed. Mtk tool and sb flash didn't work since the tablet is write protected and also I don't think is works for media tek 8 series chips like it does with 6 series chips. I was going to build twrp but you need a unlocked bootloader to flash it and when I run fastboot OEM unlock it returns three dots. I think my fastboot drivers got messed up after I unhard bricked my OnePlus and that's causing it to return 3 dots. I will try another pc and report back.
Nope it still returned the three dots. Well I'm out of ideas to unlock the boot loader. Maybe a more experienced dev can do it or we can ask lenovo nicely.
Bootloader
According to a thread on the lenovo community... the device has a mediatek proceesor, which can be flashed without unlocking anything using their SP flash tool. Only downside is any custom roms would have to be built for mediatek and using a "scatter" file.
Thread: forums.lenovo.com/t5/Lenovo-Android-based-Tablets/how-to-unlock-the-Lenovo-A3000-bootloader/m-p/1588718/
Stock Rom: androidxda.com/download-lenovo-stock-rom-models
Flash Instructions: androidxda.com/flash-stock-rom-using-smart-phone-flash-tool
The rom's source is also available on the Lenovo support site.
Unfortunately, I'm not expert at anything to make anything happen with this information.
---------- Post added at 08:48 PM ---------- Previous post was at 08:41 PM ----------
Then again, all that may have nothing to do with the A3300, since it's all based on the A3000... but same processor type? doesn't seem like mediatek has any info on their site about it either.

It was like pulling teeth, but I FINALLY got TWRP running on this tablet. It was EXTRA painful for me because the tool I use asks you to select your device resolution and like a dummy, I actually picked 1024x600 (which is the device's resolution in landscape, but not portrait mode.) When the thing finished installing TWRP and booted up, I was locked out of the tablet because the touch elements for twrp to actually restart or even unlock the device ran off the screen making using them impossible. I had to wait seven hours for the battery to finally die before I could access the thing again, (thanks for skipping the reset button on the a7-30F, Lenovo!)
In a nutshell though, I started with Kingo Root, which was successful, and then used Easy Magic TWRP Installer made specifically for mediatek devices, found on another xda thread. JUST MAKE SURE that when it says "Unable to detect your device resolution" that you choose the highest res below 600x1024 (it was like 546x964 or something like that. I can't remember exactly.) After I had a working TWRP, I switched to chainfire's SuperSU
I hope this helps.

Let me know how it works...
The biggest challenge with installing a ROM methinks though, is that you have to use the SP Flash tool to actually upload a rom. I could be wrong... I haven't tried through TWRP. It took me so long just to fix my screw up that I put it down for a while. The SP Flash Tool needs some kind of Android Scatter file, (probably a Lenovo specific MT8127_Android_Scatter.txt), which I have been unable to find or figure out from the source. I'm just not that talented.
It IS entirely possible that just applying a rom via TWRP will work fine, but it's also likely that the system will bark at you. I'm curious to see what happens.:good:
Usually you can get the scatter file for mediatek device with mkt tools but the option is blocked out when I plug the tablet in. I downloaded the cm source but I ran into my first hiccup when I use cat /proc/mtd to extract the boot.img it won't show any of the partitions.

Yeah, I think the mtk tools app is unable to access the root shell on the device for some reason, keeping it from being able to grab the scatter. I'm not sure why it's not working though. I got SuperSU installed and running on the tab, but that application still fails to get to the root shell.
I can't find any time to work on porting cm to the A7-30; Can anyone else give it a shot.?

It was dumped into the 'last_log_r' file from my last update. Then today I downloaded the lollipop OTA and pulled the scatter file from that (this is what I attached here).

Hi Guys,
Yesterday I've been tweaking my Nexus 5 and tried to dual-boot it with Android 6.0.1. I followed every guide for it and no luck, even the official one from Ubuntu. When I tried to install it as the only system, which means I erased Android, it stucks on the boot screen. I think what I did isn't correct according to the guide, but it's because I tried many solutions for it to work but it won't. Help is appreciated. Please don't close the thread, OK?

dual boot ? have you tested with multirom ? it' s the simply way to have android and ubuntu .
I didn't want to try it out because it's risk, but I guess I'll give it a try. So which channel do you recommend and which version from it, because there are a bunch of channels and versions and I don't know if they're the same or not.

make your proper opinion of version of ubuntu.
https://2buntu.com/articles/1510/installing-ubuntu-touch-with-multirom/
MultiROM installed Ubuntu Touch from the devel server and when I go to the MultiROM boot manager, I selected Ubuntu Touch option but instead of booting, it just hangs a while and reboot to the boot manager again. And I also need the name of the channel for Ubuntu 14.04. There are plenty channels but absolutely no hint
