how do i update rooted phone w/ ota update?

so sadly im still running 1.28.531.10 and want to update to 1.63.531.2, i got a file - OTA_Doubleshot_TMOUS_1.63.531.2-1.28.531.10_release_245284jzymhpvbi39cqj18.zip but it fails to flash - as a non-developer I came across http://forum.xda-developers.com/showthread.php?t=1624516 and think i need to somehow get Modaco CWM ? i currently have titanium backup and rom manager apps with - CWM 5.0.2.7 flashed.
Might be stupid question but how exactly do i load in this new update, without messing up my current setup (using trimmed stock rom rooted with s-off)?
I see the article reference calls out some "PG59IMG.zip" file
but cant i simply use my "OTA_Doubleshot_TMOUS_1.63.531.2-1.28.531.10_release_245284jzymhpvbi39cqj18.zip" that got downloaded?
I guess i need a bit more help - as feeling pretty out of it and certainly dont want to mess up my phone. I got too much other stuff going on but would like to do the update - can someone please provide a list of instructions on how to update the phone without loosing all my stuff? - like where do i get this Modaco CWM and what version i need. and if i can use my ota.zip file
i tried flashing my ota.zip via cwm 5.0.2.7 but it just errors out
Any and all help would be greatly appreciated

You can only install manufacturer ota updates with a stock recovery.
Doing the update can equate to a factory reset, at the very least will lose root - you'll have to re-root it.
Installing a PG59IMG.zip file will wipe your system.

for some reason other root methods just didnt work (i tried about 5 ) and at some point did have superuser.apk on phone but it said bad permissions, and i downloaded a "root checker" and it said i still did not have root..
but kudos to hasoon2000 -- for making the program - still dont know if i should "relock-bootloader" (i already has s-off, but used his program to flash CMR, then CMR to flash the su.zip ) but dont know what "unlock bootloader" did and if i should relock it, now that i got root up and going...

One thing I'd do is--
I apologize for being late to this thread; I would have listed a more straightforward method with source links had I referenced the conversation earlier. Be that as it may...

That's an older version of Superuser. And while it may be adequate, I recommend you flash the newer version from AndroidSU.com: http://downloads.androidsu.com/superuser/Superuser-3.0.7-efghi-signed.zip
From my experience, it sometimes doesn't want to install unless you follow these steps:
Boot into CWM recovery
Connect your phone to PC via USB
Choose "mounts and storage," then "mount USB storage"
When your phone directory shows up on your PC, copy the Superuser zip to the root of your SD card
Unmount USB storage and go back to the main CWM menu, then choose "install zip from sdcard"
Scroll down to the Superuser zip and select it. Installation should go without problems.

Erm, no. You most definitely do not want to relock the bootloader. If you have root/s-off, updating Superuser is the only thing I'd recommend. You're golden for everything else.
Hope the above info proves helpful --

I tried that the other day, however If i flash that version v3.0.7 (41) -
I no longer have "root" and my "rom manager" and "titanium backup" will not work
- the new su app did look nicer but - defeats the point if it doesn't function, im still trying to find a way to revert my phone and get the old version back in there(have to start all over). Im hoping there is a workaround for this behavior (perhaps there should be a separate thread on getting a working version of superuser 3.0.7 - as it installed fine)?

Rooting Nexus S [Help]

A while back, I always rooted and unrooted my Nexus S with no problems at all. Now whenever I try to root it, it just goes wrong. I've tried TWRP & CWM, CWM used to always work but now it just messes up. Both TWRP and CWM both give me an error that say Installation Aborted when I try to install a custom rom. I've redownloaded the rom from different browsers and even different PCs but nothing working, still that same error. Does anyone have a guide that is 100% to work without any errors during the process?

What guide are you using?

I used this one: http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/

1. Make sure you're running one the more recent versions of the custom recovery. You probably are but there are issues with older versions so just make sure.
2. Boot into what ever recovery you pick and do a full wipe. That is everything gets wiped but your SD card. Factory reset. Format /system etc.
3. Flash your ROM and gapps if they are seperate.
You should not get any errors. If your recovery is current and your flashing a new rom onto a fully wiped system and you still get a error either you're screwing something up or you may have a hardware problem.
To rule out a hw problem flash the factory images with fastboot. If those flash normally and everything works it is almost certainly user error.

Alright, thanks Do you recommend that I root my Nexus S or should I wait for the Jelly Bean update? I've rooted before and I enjoyed it but now I don't see that many reasons to root, do you have any good reasons?

I have many. My reasons for root don't matter. If you don't have a reason for root then don't root. Its that simple really.
Make sure you're on a stock 4.0.4 rom. When the ota is out install it.
If you want just root on either os at any time just flash su.zip from custom recovery. Its that simple. Having root on a stock rom does not affect the ota process.

What are your reasons for root? Please share?

Getting rid of stuff I don't want in a ROM.
Apps that do things that require root.Titanium backup/autoruns adaway ( ad blocker app alone could be its one point) etc
Changing kernel settings. Bid/bin clocks volts etc.
Being able to have a replacement launcher use the ICS style widget drawer.
Lastly , I simply just can't see having a computer that I don't have root/admin rights to. Its my damn device and I do what I want.

Oh cool. There is this project that some members from XDA are working on called Sense4All and they are porting Sense to many devices. Im probably going to wait until a fully functionable release is available for the Nexus S. I do like AOKP a lot, so that might be a reason for why I'll root.

You seem to be a little confused with some terms. Root is simply being able to grant superuser permission.
You don't need to root to flash a custom rom on a nexus. Just a unblocked bootloader. You could run aokp or any other rom without root if you wanted to.

Oh, I never knew that, haha. Is it possible to flash a custom kernel with an unlocked bootloader or does that require root access?

m1l4droid said:
No you just need a custom recovery. But using that kernel's mods, like BLN, OC, UV, touchwake, etc, requires apps that need root, like NSTools, SetCPU, etc.

Oh alright. Now I really wanna root + install a custom rom. Do any of you have a full 100% fully working guide for rooting Nexus S and which rom should I flash first? I already know what kernel I want.

Thank you so much! I rooted my phone with CWM recovery installed and Paranoid Android + gapps installed

[Q] Did I root correctly?

So I got my 300T a few nights ago.
It's already got Asus's JB on it.
Wanted to root to use the SwitchMe app for multiple profiles.
I was able to get the system to see fastboot, and ran all of the commands. Was able to boot to CWM and install root-signed. When I was trying to reboot, it said root was possibly lost, asked me to fix it, i said yes.
When I open up the SwitchMe app, it just keeps trying to open a SuperUser window about 7 times, and then does nothing else.
Have I done something wrong?
SuperUser just says No Apps in List.
edit: tried to update SuperUser. It says "gaining root access.....fail!". Guess I'll try to install root-signed again. Not sure how I could've messed it up the first time.
edit 2: wiped cache and dalvik, installed root-signed again, same problem. SwitchMe says I haven't granted superuser permissions. SuperUser shows no apps, is set to auto-allow root access, and fails getting root access when running binary updater.

im pretty sure you have to unlock the bootloader
and go through some crazy process before you can root with JB

My tablet was running JB when I bought it. I unlocked and still could not get my tablet to root using CWM. On top of that, CWM would not make a proper backup. I highly recommend you switching to TWRP. I did, flashed a rooted custom ROM and haven't had anymore issues.
Many people are having issues with CWM. TWRP is definitely the way to go. :good:

1 wrong section
2 root checker app(s)

Well, what I did to root my stock using TWRP was to flash the root-signed in the CWM thread, but as this didn't really got me full root, I flashed the flashable zip from here, downloaded SuperSU from market, there then chose "update binary" and then I had root
I'm pretty sure flashing the root-signed of the CWM thread wasn't needed, but if you do this steps (need to be unlocked to flash a recovery, strangely recommend TWRP 2.3.1 or 2.2.2 for 4.1 ROMs and 2.3.3 for 4.2 ROMs (as 4.2 has this sdcard/0 directions because of Multiusers, 2.3.3 uses this directories too))
So what should work:
1. unlock bootloader
2. flash CWM / TWRP / MobileODIN installable ZIP: CWM-SuperSU-v0.99.zip from here
3. download SuperSU from market and there update binary (don't know how it's called exactly)
4. enjoy!
if you decide to use a Custom ROM, you just need to flash the ROM in TWRP and should get Root too with the ROM (as all of them include Root afaik)

[Q] KGS1992 Utility error

This post should be inside of this thread, but I do not have 10 posts so I cannot post in the Dev forum
I own a Sensation (4G) and achieved S-OFF with HTCDev and Juopunutbear wire method. I then installed KGS1992 Utility to my desktop (wasn't working when installed in Program Files) and made sure all other windows were closed. I successfully used the utility to install 4EXT recovery. I then tried to Root and this is what happened [screenshot attached]:
On my phone it opens the recovery, opens another program (rooting tools by mike1986), and reboots my phone to the normal screen. I then hit [Enter] because the installation looked complete. The KGS1992 utility prompted me again if I'm sure the installation was completed. I hit [Enter] again but received the error:
"goto was unexpected at this time"
Am I good to go? It seems as though the installation was complete. I haven't closed the command prompt window, and haven't disconnected my phone since the incident. Any help is appreciated. Thank you.
EDIT:
Just checked with a root checker app on the marketplace and it says that I do not have root.

Hi
What do you intend to do with your phone? If you want to install a custom ROM, then forget about rooting. You have s-off plus 4ext recovery; and custom ROMs are normally pre-rooted.
Otherwise, try simply rooting your stock ROM with ERoot, a program for windows.

I am very new to rooting, but I've been reading threads for a while now trying to understand. And yeah, I would like to install a custom ROM.
Thank you for the help, I am fairly sure I understand now. Is my understanding right that I can go into 4EXT, make a backup of my current factory ROM, download a custom ROM, and replace factory with custom. If this is right, I'll browse for which custom ROM I want now I dislike the factory bloat.

P5113 root, recovery, rom questions

Hello community,
I was given the device last year and had been fairly satisfied with the performance of it. However, it has gotten laggy over the past couple weeks and a friend suggested to root and flash a rom on it. So, without any prior knowledge, I have been doing some research and browsing through the threads on this forum. I can see that there are guides but was very unsure if the methods would still work because I have noticed that most of them were last updated/edit a while ago. I know I shouldn't use the word 'latest' for doing this to a tablet that is fairly old in the market. However, it would be very helpful if someone can point me to some 'proven to work' or 'trust-worthy' guides of rooting, flashing recovery, and rom.
Also, just out of curiosity, please recommend which recovery and rom a first-timer should use if possible

try these roms.

( settings. < about device < touch build number 7times < go back and select developer options < check USB debugging.)
-Open kingo root on the PC and connect your device and connect your device to the PC. Start root and do not remove the USB cable until it says finish.
-Now you have successfully rooted your device.
2.HOW TO INSTALL A CUSTOM RECOVERY
- Go to the following link and download CLOCK WORK MOD(CWM)
LINK: https://www.clockworkmod.com/rommanager
Select your device and install the recovery.
go into the app and install recovery .
3.BACK UP
download rom manager from playstore and do a backup( do a backup using this ap only if you are using CWM recovery.
link for ROM manager: https://play.google.com/store/apps/d...mmanager&hl=en
Now the first thing you need to do is download this rom.
https://www.androidfilehost.com/?fid=95916177934533333
(note: you can flash the rom of p5110 for p5113)
now to flash the rom follow the following steps.
1. Go to recovery mode
2. (have the rom in your sd card)flash it there .
use this link to know how to flash a rom.
https://www.youtube.com/watch?v=tJfPwWjnWGY
now you can reboot after flashing.
to get inbuilt google apps and play store you need to install something called GAPPS (Google apps) download from this link.
http://opengapps.org/?api=5.1&variant=nano

I was looking in the forum and someone said that I would also need to unlock the bootloader? If so, how do I do that?
Also, is there a difference between kingroot and towelroot? I saw a post in the forum here saying towelroot is fast and easy to root the tablet.

Not much difference.
Actually there is not much difference between kings root and towel root....towel root doesn't need a PC...but I have never used it so I can't assure you that it is safe.
And coming to the boot loader I don't know much about it but I didn't do anything like that before flashing a rom or rooting my tab2....
If you want further assistance about the boot loader I can help you with that..

Hey, it's been a while. Honestly speaking, when I first posted this thread, I didn't really have enough time to do the things so now I am finally back and trying to do it. So far, I know what recovery and rom I'm going to use with all the files downloaded and ready. Though, currently, I am still at the pre-root stage. I have read up things about kingoroot and not sure if I wanted to use it. So I looked around on the forum and wonder if Odin is still a working solution. Reading on the steps and guides, I was wondering if I need to have Kies installed?

Kies is not needed as it never helped.
You can depend on odin it is your only saviour when you are in trouble.
I think rooting with kingroot is easy as it is just connecting to your PC and cick the start button.
So just notice me when your ready.
And there is also one good news...?
Tab 2 has got marshmallow.

I have rooted the tablet. I did it with odin and twrp with flashing the updatedSuperSU zip folder.
I have tried flashing the CM12.1 rom yesterday but resulted in a boot loop. So for now, I'm just rooted and on stock rom until I or someone can find out what was the problem. I have read about the discussion with marshmallow but it seems to me that the project isn't really stable yet. From what I have researched lately, can I assume there's issue with the p51xx line of tablets? Because I saw many people having problems with p51xx and most people with the other tablets aren't having any.

You first must update your tab to jelly bean bootloader, before trying out newer roms.
Or perhaps flash stock jb firmware with odin
Whatever you choose, both is ok.
http://forum.xda-developers.com/showthread.php?t=2642005
Read here
The first thing you do, is take a nandroid backup, it's very important at every step, unless you are really ready to risk. It's better to have it.
Next Read through the rom threads, clear your mind and your tab too. You must format data.
Stay on twrp 2.8.7.2. Don't go to the latest one yet.
Flash rom, wait, it will boot up.
Every tab behave differently with every rom, sure you are going to face soft reboots, on some roms it will be a lot, on some it will be less. I would suggest you try both LP and kk first.
Remember, it's better to keep this tab updated than to stay on stock. This tab 2 series has a emmc bug and staying on stock or jumping back is a risk too. I have been on kk and lp. They both have kept this tab running great and away from that bug.

Do I have to unroot first? Do you have a link to making a nandroid backup?
Edit: Oh, I looked at the link you included and it said that if I am on stock jb (4.2.2), I can skip the update bootloader part..

When you flashed the new rom, did you do a factory reset (wipe data)?

Edit: Oh, I looked at the link you included and it said that if I am on stock jb (4.2.2), I can skip the update bootloader part..

Yes, that's what I meant too, if you're on jb already, you are fine. You don't have to unroot. For making a nandroid backup, use twrp recovery, there is an option for backup, select and backup all from there, if you get into bootloop or any other problem, as long as you can get back to recovery, you can restore from there. Most rom comes pre rooted.

I have rooted the tablet. I did it with odin and twrp with flashing the updatedSuperSU zip folder.
I have tried flashing the CM12.1 rom yesterday but resulted in a boot loop. So for now, I'm just rooted and on stock rom until I or someone can find out what was the problem. I have read about the discussion with marshmallow but it seems to me that the project isn't really stable yet. From what I have researched lately, can I assume there's issue with the p51xx line of tablets? Because I saw many people having problems with p51xx and most people with the other tablets aren't having any.

Did you clear dalvik cache in recovery before flashing rom?

Yes, I cleared the top four options in recovery, and formatted data before flashing.

That's what I did. Let me just briefly summarize what I have done:
used odin with twrp
booted into recovery and made back up
cleared dalvik, cache, system, and data, formatted data
flashed update supersu, booted into system and checked root with root checker
rebooted into recovery, cleared dalvik, cache, system, and data, formatted data again
flashed cm12.1 and gapps, rebooted but ran into bootloop at splash screen
rebooted into recovery and restored back up
So I'm rooted and on stock 4.2.2 currently.

When you flashed the new rom, did you do a factory reset (wipe data)?

I did.

Try flashing blisspop or slimLP.
