I have recently rooted my gs2 and am running the latest Siyah kernel on the stock ics rom. After installing Rom Manager and installing the oneclickuser recovery (or something like that) in Rom Manager, I began a backup of my current (stock ICS) rom via Rom Manager. It began to restart the phone and then....blank. Now all I can get to appear is the gs2 logo/orange triangle screen for several seconds before going blank again. I would really appreciate some immediate assistance. Thank you.
Should have read first, why are you using Rom Manager? How many threads does there have to be about this?
I'm going to jump in here before you start getting all sorts of "don't use rom manager" and "search first" and similar answers.
You can't use rom manager successfully as you just learned, but you are not bricked. Your phone is recoverable.
I'm not certain exactly what became damaged in the firmware, but most likely the only option you have is to use Odin to flash the stock firmware and start over. Please follow one of my guides which will give you all the information you need, and assuming you want to root and install ClockworkMod Recovery, then use the guide for installing custom binaries without incrementing the flash counter.
The only way to get ClockworkMod Recovery on the SGSII is to install a custom kernel containing it, and you need to be rooted to do that. That is the only way you will get a nandroid backup of your phone.

Thanks for your help. I have been trying to locate the stock ICS ROM package on the forums but have had no luck thus far. Can you possibly point me to the stock ICS ROM?
Using Odin, I will essentially be flashing a new (stock) ROM over the existing stock ROM and Siyah kernel? I am just trying to figure out what parts of your "How to Flash Custom Binaries Without Ever Incrementing the Flash Counter" guide are applicable to my situation...seeing how I am technically already rooted.

If you need to use Odin then you need to download a stock firmware from the download repository.

Okay, I have located "I777UCLE5 Stock Binaries (Android 4.0.3 Ice Cream Sandwich)" from the Download Repository. Is it ideal for me to flash the firmware version containing OR excluding the boot.bin primitive bootloader? Both options are available.

Without the bootloader. You shouldn't flash the bootloader unless you need it.
However, if you want to flash UCLE5 plus root, that is here. And read the thread. You should flash a custom kernel right away, so I would recommend this instead of straight stock.

Hi all,
Excuse the noobness but trying to get my head straight before I dive into rooting and flashing custom ROMS
I currently have a Telstra Australia S2 on kernel DVKF4. My aim is to root and flash Litening ROM
I think to flash Litening ROM I do not have to Root I can just go ahead and flash it however I would like to take a backup of my current firmware first, if I go ahead an install Litening my original Telstra will be gone and wont be able to back it up now?
If I understand this correctly I first need to root and I need to flash an insecure ROM. Now currently the DVKF4 insecure ROM hasnt been uploaded yet... Can I use any old kernel to get root access?
I know if I do this I will get the yellow warning label but will this even matter since after I gain root I am going to flash litening anyway so that will replace the kernel anyway with the litening one and I will not get the yellow warning. Correct?
Anyhoo I wanted to backup current Telstra firmware in case I need to flash it back for warranty. Also I would have to unroot it. So in order to do this I would firstly restore the backup made which would flash back the original telstra ROM but the phone will still be rooted?
Since I made the backup with the 'any old' kernel to get root does that when I restore I am going to have that kernel still on phone and giving me yellow warning?
OK so I would have to flash back the correct DVKF4 kernel to get rid of it again. So I would have to flash back the original (secure) kernel to get rid of this and user superoneclick to unroot and then its back to its original state? (besides the download counter of unsigned ROMS which can be reset with jig)
Also does the yellow warning come up even if you use an insecure kernel which is the same version your firmware needs?
I thought it's the kernel which gives the root access but it's not is it? It just allows superoneclick to install the superuser files etc?
Thanks!

True but you may find copy on Branded roms post dev section or use vanilla Samsung stock rom .
If I understand this correctly I first need to root and I need to flash an insecure ROM. Now currently the DVKF4 insecure ROM hasnt been uploaded yet... Can I use any old kernel to get root access?
Depends upon what the instructions say but generally as near to possible as your rom .
I know if I do this I will get the yellow warning label but will this even matter since after I gain root I am going to flash litening anyway so that will replace the kernel anyway with the litening one and I will not get the yellow warning. Correct?
Incorrect you will need the USB recovery jig to remove the warning and reset the custom rom counter to zero the easy way .
Anyhoo I wanted to backup current Telstra firmware in case I need to flash it back for warranty. Also I would have to unroot it. So in order to do this I would firstly restore the backup made which would flash back the original telstra ROM but the phone will still be rooted?
A backup via CWM of a phone will restore what you backup .
To restore unrooted you will need to save unrooted in the first instance .
Original rom or branded rom flashed via Odin will remove root .
I thought it's the kernel which gives the root access
Yes if you use the usual method no if you use another method .
Root & CWM kernel.

Hey thanks but how do I make a backup of the unrooted current carrier ROM? Don't I first need to gain root access to be able to run CWM and make the backup?
Or is there a way I can go into recovery now with the device currently unrooted and stock carrier ROM and make a backup?
Thanks

As was pointed out above by JJEgan, either wait for the Telstra carrier branded firmware to hit this thread.
Or you can try the root/unroot method as described here. Good luck

yeah thanks I get that part it's just that he mentioned if I want back a backup of an unrooted rom I need to make the backup while unrooted but I did not think this was possible since you need to root first before being able to backup?
Just after some clarification about that.. Thanks
I have a i9100 rooted CWM (forgot the kernel name) and MIUI installed. I would like to change to the most currect ICS available for it without using custom roms.
Selling to a friend who wants it more or less reverted to the manufacturer. I live in the US and I seem to need assistance with this as its been a while since I've done it.
I'd like to get the best kernel on there too and root after flashing back to ICS as well as keeping my contacts on my sd card.
Search for a stock ics firmware and flash it with Odin.
Here a post that may help you.
Is it just a matter of installing from the SD card like you normally would when flashing custom roms?
Would it lose the root?
Also, the post you mentioned doesnt have any american versions of the ROM. Would that matter? Im just wanting to make sure it will work with ATT and be in English
Here a thread with more information.
With Odin you must connect the phone to PC in download mode and yes, you will lose root flashing a stock firmware. After you can flash an insecure kernel (Chainfire's for example) and gain root again.
What do you mean by insecure Kernel?
And is it going to matter if I install the rom from a different country?

It is prompting me to install the update again and again.
My question is, if I do select to install this update,

Device status modified and cannot update
tried using triangle away and did not reset the flash counter
Because triangle away can reset your flash counter only if you're running stock recovery, stock kernel, stock rom etc.
CF-AutoRoot should not make your status "modified" but probably like you see it did. Maybe some other apps did that, maybe not, nobody knows anyway. If you really need these updates then you should flash newest firmware from samsung through odin and then root it + reset flash counter, it should work also for further updates (but I'm not sure).

Thanks a lot.
I know where to get the FW updates to flash via Odin but don't really understand how to reset the flash counter if not by using TriangleAway.
Could you please be kind enough to guide me?
And these are the apps I used after root
SuperSU
Busybox
Root checker
Titanium Backup
Lucky patcher
Market enabler
Greenify
Could any of these apps modify the stock kernel, rom or recovery? Coz I never flashed any custom ones just rooted using CF-Auto-Root and installed the root apps
P.S: I was able to do the FW update via Kies and now the status is back to normal, but I'm afraid to root coz the status might go back to modified.
It's more like, you know. If we're talking about warranty then they'll find that your rooted your phone anyway. If we're talking about updates then probably it's still better to keep an eye on some stock-based custom roms, mostly because of frequent updates (nearly instantly after new baseband), while you still need to wait some time for OTA to arrive. Of course it's much easier to apply OTA than whole custom rom but hey, how often are you doing that?
About your question - busybox is my choice because it modifies /system apps, many of them.
And lastly - in odin you have a checkbox to reset flash counter, so you don't need to worry about anything using this tool. At least in general.
Overall I'd stick with pure stock non-rooted firmware if you don't need it in general or rooted custom rom (f.e. mine ) for much better experience. I couldn't go back to stock after getting used to much better performance, less battery drain etc.
Choice is yours.
Lucky patcher
Warez is totally banned on XDA you are stealing from developers .
As its a warez app who knows what sort of malware it could add to your phone .
I would wipe the phone install original firmware .

Thanks for the quick response
I rooted mainly coz I needed to use market enabler
In Odin are you referring to the option F. Reset time??
I am using the Odin version provided by Chainfire in his S3 rooting thread in which all options are disabled except for Auto reboot.
@JJEgan I don't even know how to use half of the apps I mentioned, I only installed them as my friend suggested it as must have root apps.
As you might see, I am still a N00b at this and am in the learning process.
BTW Thanks for the link to the guide.

If I'm not mistaken, ArchiDroid is a Custom ROM(pre-rooted) which requires a Custom Recovery.
I will be learning a bit more first before I install a Custom ROM.
A question though. Will I have to take a backup of my app data if I decide to install a custom ROM?
Also if I want to install the stock FW via Odin, will I have to take a backup first?
Thanks and I'm really sorry about asking such questions.

Yes it requires custom recovery for installing .zip package.
There is nothing to learn if you ask me, you have complete guide for installing everything you need in step-by-step howto. If you want to keep your data then you need to use some nice app for that f.e. Titanium Backup but for that you need root and... yeah. It's easier to start from scratch on new pre-rooted rom.
I'd suggest flashing custom recovery (tutorial in my topic) and then you can create a backup directly from that, with everything you want to, including actual system, efs folder, recovery, kernel etc. So you can easily get back to original rom whenever you want to. Keep in mind that you still need custom recovery for that.

Ok Now I'm really confused
I still haven't learnt how to use Titanium Backup to backup, or how to do a nandroid backup. I have read it's better to do a backup b4 installing a custom ROM. And if I'm not mistaken, I need ROOT to do a nandroid backup too.
As I said before that I used CF-Auto-Root, I just followed the instructions to the word.
I had tried doing a ADB backup before root, but for some reason it kept exiting(I guess coz I have just about 1GB memory left on my Internal memory SD card)
Thanks for the quick reply. Man ur really fast in answering questions. :good:
EDIT: Just did the CF-Auto_Root again and didn't install any other apps like busybox(uninstalled all root apps) and used triangleaway to reset the flash counter. But the counter still stuck on 1
The device status shows normal though.

First of all you need custom recovery to perform nandroid backups. So you can stick with my first 10 steps in my howto. After that enter recovery, enter backup section and make a custom backup (or default, doesn't matter) of everything you have, especially /efs folder as it's really important. When you finish doing backup then boot to your normal system and copy these backups to your PC. Now you're sure that they won't disappear and if you want to backup your phone from that then simply put them back on your phone and restore them from the recovery.
But overall I'd suggest clean start without these backups. Of course it's always recommended and I recommend it as well but as long as you won't want to go back to original rom, there is no real point for backing it up. You can always download latest official firmware and flash it through odin.
Hello All. I had installed SHOStock 3.0.1. Then I somehow thought that I will back ROM and that reminds me of ROM Manager which I installed ages back . Clicked on backup which restarted the phone and then phone didnt start ever. So I put back Stock Gingerbread UCKH7. But now after that when I am trying to update using AT&T software update, it is giving me error that software cannot be installed due to interrupation. When I try to install from Kies, office laptop does not recongnize my phone. Home laptop do recongnize the phone but gives message that this version of Android is not supported to upgrade by Kies. I dont know how shall I proceed. When I try to install stock ICS downlaoded from some XDA thread using ODIN, it is not doing anything. Tried to use Exynos Abuse to root but not working. Any other tool to root? Is it ok to directly install some Jelly Bean ROM after root on Gingerbread or shall I go for ICS first then JB? PS: Tried to read thr' all stickies and Q & A but could not find proper answer. Thanks in Advance.
I hope you didn't do any permanent damage by using rom manager. If you did all the reading you mentioned, you probably saw, after the fact, the sticky thread warning not to use rom manager.
First, you can not do an over the air update any longer; the only way to update officially is via kies. Not sure what is blocking kies, but you might try entering 3e recovery and performing a wipe data/factory reset, then see if kies will install the update. You do have to be bone stock for kies to work, I think. Rooted may be ok. Not sure exactly what elements causes kies to fail.
I mention the possibility of damage because you say:

You should be able to flash any of the stock firmware via Odin.
If you want to go the custom firmware route, you can install a custom kernel, then use ClockworkMod Recovery to install your custom firmware. You should be able to do this from any version, Gingerbread, ICS or JB.
You can root by flashing one of the stock plus root packages. Exynos Abuse only worked with 4.0.3 I think. The exploit was patched. People have been using Framaroot to root stock 4.1.2, and I believe someone mentioned using it successfully on ICS as well. Results posted here have been mixed but generally successful.
There are several resources in the Download Repository. See the link in my signature.

Assuming that Helly Bean uses a CWM flashable zip file, as almost all rom's do, then you will need to install a custom kernel containing a CWM recovery. You can not flash rom's from stock recovery or Odin.
I have taken my stock nandroid backup for granted and now more or less no longer have access to it, as it is sitting on an external hard drive thousands of miles away from me. I am beginning to regret that.
I need to get back to a "stock" state in order to do a SIM unlock. I put stock in quotes because am not exactly sure what that means as far as how far I need to go. Do I need to flash a stock recovery? Do I need to unroot? Can I just flash any stock ROM and have that be enough?
I have a 900T3 and am currently on the GPI1 firmware. I am aware of the sammobile firmware downloads page and am totally fine with flashing any of those. Although, I'm not sure if I need to manually update one by one, or if I can just flash the most recent one and be fine with skipping everything in between GPI1 and the most current.
Is there somewhere I can download stock ROMs specifically for the 900T3? Can I use stock ROMs for the 900T and have it work? What do I need to get a stock ROM to successfully boot? Matching firmware/ROM versions? Stock recovery? Just do a wipe and flash the ROM in twrp and I'm good to go?
Thanks

Although, I'm not sure if I need to manually update one by one, or if I can just flash the most recent one and be fine with skipping everything in between GPI1 and the most current.
Is there somewhere I can download stock ROMs specifically for the 900T3? Can I use stock ROMs for the 900T and have it work? What do I need to get a stock ROM to successfully boot? Matching firmware/ROM versions? Stock recovery? Just do a wipe and flash the ROM in twrp and I'm good to go?
Thanks

You can use the Latest Stock Rom Version, for me it was a 4.4.2 BNH5(worked best for me) for the G900T.
Backup all of your pictures etc first then use Recovery to wipe the phone and use ODIN to install the firmware.
Awesome. So I'm on GPI1, do you know if I can downgrade firmware from here, or can I only go forward? I did want to update anyway, can I flash to the most recent first or do I need to flash up to the most recent individually?
There's one newer than GPI1. Just download the image from sammobile and flash it from Odin. The phone will then be 100% stock.

It is a TMobile Phone- So you can upgrade or downgrade. ATT and Verizon are the only 2 I know of that Lock Their Bootloaders down to prevent downgrading.
