So I successfully rooted with zerg rush.

I backed up my EFS

I used Ti to back up my user apps

I am backing up my sms stuff now

How do I do a nandroid backup without having cw?

i went into the market and installed rom manager, then flashed clockwork mod, then went to do a backup but it failed because it couldnt find an update or something. i just rebooted, and my phone turned on, looks fine. how can i a) get rid of that, and b) backup my phone?

I rooted my S2 with zerg rush.

Have Superuser with granted access for :

Rom Manager , Titanium Backup , Root Explorer

Can change RW/RO mod.

Flashed CWM in ROM Manager

When I try to backup via ROM Manager got

E: Signature verification faillure

a ) I read about the CF-Root but dont know if i am allowed to use this Method after i've allready zergrushed.

b) CF-Root does not allow me to backup via ROM Manager , as it is written in the description that is not working with RM and installs an owon CWM Manager.

You need CWM to nandroid, to get it, flash this kernel

Yes you can flash CF-root even if you have used zerg rush. CWM Manager works just as well as Rom Manager.

Hi could someone explain the difference between the zergrush exploit and CF root. I rooted my sgs2 using cf root ages ago but my friend got her hands on an sgs2 recently. The zergrush exploit seems to not increase your binary counter but I read somewhere that it isn't a full root which confused me.

sea_salt,

While your post is very helpful, I just wanted to point out that your hyperlinks in post #1 are not functioning. You should probably fix them.
[Galaxy S II Q&A, Help & Troubleshooting] bpivk:
zergrush exploit doesn't increase your count but it only gives you root (it doesn't give you CWM recovery). BUT you can use mobile odin to flash a different kernel and it won't increase you count but you will have CWM recovery. I did that and my counter is at 0 (I don't hame my USB jig yet) but I do have siyah kernel and CWM recovery.
[Galaxy S II Q&A, Help & Troubleshooting] drigz08:
Question = Do you need to flash 2.3.5 to do zergrush?

Answer =

No if your Gingerbread version is 2.3.3, 2.3.4 and 2.3.5.

Yes if your Gingerbread version is 2.3.6(specially novermber released) and above.

This method will 100% work on 2.3.3, 2.3.4 and 2.3.5 gingerbread versions.

If you have 2.3.6, you need to flash 2.3.5 or lower first.

Note:Flashing kernel only will not work. If you have 2.3.6, You must flash [2.3.3, 2.3.4 and 2.3.5]the whole rom+kernel.

Also some 2.3.6 released earlier than november, this exploit may work.

Additional info, you can add this on the first page:

If you just want to remove yellow triangle from a 2.3.6 rom.

1. perform Nandroid backup

2. Flash 2.3.5 (or lower) rom+kernel package then do zergrush method (zImage CF-Root or any rooted kernel)

3. Restore Nandroid backup, and you can now flash any non secure kernel from recovery

Yellow triangle gone.

thanks for sharing

i had to take my sgs2 at the maintenance since i broke the screen :(

i gonna receive it today with a 2.3.5 or 2.3.6 official rom

i would like to install custom roms and kernels avoiding increase on binary counter if possible

what i have to flash and how?

i understand that first step is 2 downgrade but how do i downgrade? ?

can you enlighten me please?
[Galaxy S II Q&A, Help & Troubleshooting] bpivk:
You downgrade by flashing another (older) rom. You can use 2.3.5 and then root it via zergrush. You won't increase the counter (EVER) unless you flash an insecure kernel. But you can flash one if you use mobile Odin app and flash it from there. It won't increase your counter and you'll have a custom recovery and a fully rooted phone.

That was the method I used and it worked perfecly. I'm on siyah's kernel and my counter is at 0 without any warnings (exclamation mark at startup).

I put ICS v4.0.3 (supposedly officially leaked Samsung version) on my phone using a youtube tutorial and Odin blah blah...

My question is, can I root using the zergrush exploit v4 while running ICS instead of the stock android version? If so, are there any details I should know? Thanks
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
If it's leaked, I for one don't consider it official. And I don't think zergRush works with 2.3.6. I REALLY doubt it works worth 4.0.3.
[Galaxy S II Q&A, Help & Troubleshooting] kuckimonster:
Ok thanks, so then what are my options? I found out I hadn't rooted when I installed Titanium backup. I though that by putting ICS through Odin it was automatically rooting it?

I've tried reading a bit but it seems all chinese to me. 'kernel', 'root', 'flash', 'superuser', 'CWM' all those verbs and nouns just confuse me and it feels like a rather daunting task... :(

EDIT: DONE! Used (can't upload link since I'm a noob) and worked like a charm.
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
No offense, but given what you said in the last sentence of the first paragraph, and your entire second paragraph, your options should stop at remaining at stock, until you read, read, and read some more until you understand. If you don't understand, then you should not personally be doing any modding to your phone. At all. Else you will just be begging people for help to get your phone working again.

rooting

Hello all,

Noob here...I have a T-Mo SG2...and I want to upgrade to ICS...so I need to root the device before I do my Titanium Backup...when reading the program on Easy Rooting tool kit 4.0 (is this want I want to use)....what got my attention is that it says will remove Google Maps if required....I like google maps and would like to keep or re-install it.

Any all information will be greatly appreciated.

ctomgee...

Sorry for not posting my carrier, but it T-MO USA

android version 2.3.6

Kernel version 2.6.35.11

build: gingerbread.UVKL1
[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
Then you are in the wrong forum. T-Mobile USA Galaxy SII is the SGH-T989, which had its own, separate forums. This is the forum for the GT-I9100, also known as the International Galaxy SII. They are totally different phones. Firmwares are NOT compatible between the two.

Edit to add: to be sure, check the label under the battery. It will contain a model number. If your model number reads SGH-T989, then you want to be in the SGH-T989 forum instead.

Edit 2: a quick GOOGLE of UVKL1 shows that is indeed a firmware build for the SGH-T989. Go to that forum instead. Don't flash anything for the GT-I9100, or any other model other than the SGH-T989, for that matter. Unless you WANT to brick it.

Thanks for the FAQ. Does help me, coming from the iPhone scene the Android mod community is way more advanced!

Two questions,

When I dial *#1234# on my phone, this is what I get:

PDA: I9100JPKJ2

PHONE: I9100XXKI4

CSC: I9100JPKJ1

If I understand correctly, the XXKI4 stands for Modem/baseband version and is specific to certain geographic regions...am I right?

JPKJ2, stands for the software on the phone? If this is the case then is it possible to flash different base bands on a phone?

On another note, I have been trying to update my phone via kies and I get the error that "your device does not support updating via kies".

I am on stock 2.3.5, rooted with Zerg.

[Galaxy S II Q&A, Help & Troubleshooting] ctomgee:
How is this on-topic to this thread? The rooting method of this thread has nothing to do with flashing kernels. Nor does it work with ICS. (please see forum rules regarding keeping posts on-topic)

That said, it sounds like you are using the wrong insecure kernel for your firmware. ALL the threads for rooting with insecure kernels that I know about have very detailed instructions on which kernel to use. Follow those instructions more closely.

[Galaxy S II Q&A, Help & Troubleshooting] ldiamond2:
I'm not sure if I missed the answers to some questions but...

What exactly is zergrush modifying on the device? From the source code, all I see is that it copies the shell binary to /data/local/tmp and setuid to run as root. That's done after gaining root access in the current shell by using some buffer overflow exploit. Is that right?

Is that all? All I need to do to unroot the phone is remove /data/local/tmp (assuming no other app created copies elsewhere).

Ultimately, what I want to do is backup everything from my phone so that I can revert to full stock whenever I'd like. I assume zergrush to root and then with root access I'll be able to backup the rom, kernel, etc.

---------- Post added at 06:31 PM ---------- Previous post was at 05:52 PM ----------

Figured it out! So I'll answer my own question:

Zergrush uses a buffer overflow exploit to grant root access to the current shell process. Killing the current adb shell session won't work because I suppose it's just a forked process and the process it's being forked from keeps root access. Rebooting the phone will undo what was done by zergrush... except that you'll still have stuff in /data/local/. You can wipe that out as needed.

Once you got root access you can keep your door open by adding the su binary and superuser.apk. You can add any other utils too. Next step for me is to compile su and superuser.apk and push them in and see how that goes!

Unrooting your phone is then as easy as removing the stuff you added. However, any app that had root level access may have tampered with your system and created a backdoor for themselves.

I got a question. Is it possible to flash a different kernel with the zergrush exploit? A kernel which has CWM? Someone posted on another forum that he replaced the zimage with some CF-Root kernel and then he had CWM without flash counter increase.

He used some rooting software from the Galaxy Nexus section which basically also did the zergrush exploit and he just replaced some file I think it was zimage. I've researched and no one on xda has made any guide or reported that this works so I was wondering

The last post in the thread doesn't give ANY links what so ever to the files he's talking about, but following the OP directions, the phone does not stay in HBoot to downgrade it, as soon as the zergs send and the phone reboots, it auto reboots again. FAST BOOT is off, Debug is on, Drivers are installed CORRECTLY, no Sync software or itunes even has ever been installed on this computer. But I run the tool as admin, including the hack-vivow.cmd and it completes, but doesn't do anything to the phone. Help?

[Verizon Droid Incredible 2] speedfreeq:
Part of the revolutionary root process writes a file called ".17 somethingorother" to the sdcard. Seems like I've never rooted a phone without an sdcard, because alot of the processes and apps require you to place some .zip file on the root of the sdcard.

To lead off with "before anybody flames me for being a noob..." comes off pretty arrogant, and implies that you know it all anyway, so why should anybody help out?

Fwiw, I had zero issues following the same guide, and I can guarantee the links are there.

SD card method of rooting is well known to the manufactures and that is why the newer PPCs and tablet devices are bieng "AppHoleIzed" as in Denial of User Up Gradable Storage. :eek:

That is the main reason that I will have nothing to do with the GNex.

Even the XTC clip requires the Micro SD card.

All the BS from manufactures about allowing root, just means that pay just enough attention to the forums to find ways to con us into thinking that is what they "will" do. Yea wight...

That's the main reason Willies' P Hone 7 is not doing as well as WinMo phones.

Check the forums, WinMo is doing more with an End Of Life OS then AppHole has done since the beginning.

SamSkum is going to find real soon that MOST people are NOT going to put up with a device that is locked down and so loaded with Operator Bloat that it sucks the data that now cost so much.

Root IS a vital option for people that want to actually use a device for productivity AND entertainment.

Corporate greed is going to bite them in the ass so bad they will start looking like QWest when they had to sellout the wireless just to stay afloat.
