Help: Cant Flash Roms on the S2 - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
Got my s2 rooted again and thinking of flashing a new rom. Basically, i rooted it with tegrak's kernel.. instant root/unroot without rebooting.
So I also flashed cwm recovery through Odin
Im able to access CWM but cant flash any roms. I get stuck at the screen with "Samsung Galaxy S II " and a yellow triangle.
Im not sure whats actually the problem. The bootloader? The rooting method? The Recovery?
Hoping a few mates out here can help me out.
Note: Im able to flash any roms through Odin though

If you are able to go into recovery , wipe data, cache and dalvik if possible. Then flash a stock GB/ICS Rom and root it with cf root. If you did everything right you should be able to flash.
A thanks is appreciated if i helped you in any way

Try to root with ChainFire's kernel.
But, first, re-flash an ICS FW. Then, apply CF-root-kernel.
Go to CWM recovery and try to install a rom again.

Ah. i see. So the fault lies within the tegrak kernel itself?
Il try once more tonight. Thanks for your help

Ok, rooted with cf kernel. Otw to installing CWM. See how it goes

oh yeah. works. Thanks

Need help .. How can i boot my phone now

Hi guys im currently using CheckRom V7, but i kinda brick it too..
When im done of flashing V7, i did wipes again which its not recommened in the thread, now my S2 just stock in the booting logo.
I've tried to use Odin to flash another rom, but unfortunately my s2 cant connect with my laptop, it always said unable to install the driver, but my other S2 could.
Now i think the only way is to install CWM Recovery into my phone via update zip from external SD card, because V7 is using stock Samsung kernel which does not have CWM in the phone
And i have found few threads about update zip, but they are all about rooting. I guess theyre not the ones im looking for ..
Can anyone help me with this ? Need that update.zip so bad now..
Really appreciate you guys...
Calm down man, your phone is not dead yet. The people who did wipe has the stock kernel with CWM recovery in it. You are lucky you wiped with stock recovery. Anyway, have you tried plugging it in a different usb port?

You can flash a Cwm flashable zip in stock recovery and get a temporary cwm. From it, you can reflash the rom and kernel.

You will need a rooted Galaxy S2 to install all ROM/kernels.
NOTE: PLEASE ONLY INSTALL ROMS INTENDED FOR YOUR VERSION OF Galaxy S2! Otherwise you WILL BRICK YOUR PHONE and I will not be responsible! ALL ROMs on this site are ONLY for Verizon Galaxy S2!
First time to rooting and custom ROMs?
Please see our FAQ for your Galaxy S2 model FIRST!!!:

I wouldn't have tried this as your phone is i9100P, although I know the difference isn't that big.
Also, was your phone rooted? It had to have been rooted beforehand.

Hi, yes it was rooted prior to this, but i thought the only difference was that the P version had NFC - but now it seems I am stuck at the boot screen - any ideas? I would appreciate it a lot!

That's your problem. You were on 4.0.3, which is ICS.
The instructions at galaxys2root.com/galaxy-s2-root/how-to-install-clockworkmod-recovery-on-rooted-galaxy-s2-i9100/ don't specify, but they are for Gingerbread ONLY. The recovery kernel contained within that zip package is ClockworkMod Recovery 4.0.1.4, which is for Gingerbread.
This thread (http://forum.xda-developers.com/showthread.php?t=1118693) is the updated version of that recovery kernel for ICS.
You don't have to flash the full firmware, just flash a kernel that is meant to work with ICS and you should be fine.

Thanks for the advice - but i already have the stock ROM on an SD card so i think i will flash this. Problem is i cannot get CWM to read from the external SD card, so i cannot locate the zip and install it - help?
EDIT: if i install the kernel you gave me the link to ([KERNEL][ICS] ClockworkMod Recovery 5.5.0.4) , will it remove the root access i had?
EDIT 2: I have just flashed the kernel via odin, and it finally got past the screen with the yellow triangle! However, it is now stuck on the second screen which shows the 'S' logo with the words 'Samsung Galaxy SII' under it. Any more ideas?

Can you boot to recovery? If so, you can try a factory reset/wipe data. You'll lose all your data, (not counting pictures/media) but at this point, do you have anything to lose?

I just tried that, i can boot into the new cwm - have nothing to lose since i've only had it for about 3 days - however even after the wipe data, cache and dalvik it is still stuck on the 'S' screen now

Well, now I'd say you need to flash a full firmware. You said you downloaded I9100PXXLPH from here? Should work. But you'll no longer be rooted, and you won't have CWM recovery.
How did you get into this in the first place? You wanted CWM recovery?

I will be sure to try that, and basically earlier today i rooted it successfully, and then i had to get CWM onto it so i could start flashing new ROMs etc, and i tried installing CWM via that method that has now caused all of this
Never the less i will try your suggestion, so should i basically mount usb from CWM, then copy the firmware over to the phone, unmount, and then wipe, and then flash it finally?
EDIT: it wont allow me to mount USB in CWM
can i just flash the ZIP using odin in download mode, or does it have to be a .tar file?

No. That download is for a package that must be flashed while the phone is in download mode. That will require you to use a computer, and a flashing tool, such as Odin or Heimdall.

How would I go about flashing it in download mode, i really have no idea as I don't think you can flash zip files in odin, forgive me for all of the questions I really appreciate your help!
EDIT: I have unzipped the file and hooray lies in it the .tar.md5 file! I am in the middle of flashing this and will report back on results
Thanks a lot guys!!
THANKS GUYS FOR ALL OF YOUR HELP, my SII is now working fully again! Cheers to all that helped, flashing the stock firmware worked with wipe/cache
Can't thank you enough!
Last thing if you don't mind, i want to root it again using this: (http://forum.xda-developers.com/showthread.php?t=1321582)
Now after that, how can i install CWM without getting into the mess i got into today? cheers!
Nope, I think that's for GB. For easy root use method 1 from 1st guide in my signature.

Well I think Chainfire's CF-Root kernels (http://forum.xda-developers.com/showthread.php?t=1103399) are not for i9100P, so not sure if he can achieve permanent CWM recovery. Anyway if he don't plan to flash every hour new ROM he should be fine with latest temporary CWM 6: http://forum.xda-developers.com/showthread.php?t=1840223 although will ask Phil about compatibility.

GS2 stuck at yellow triangle, cannot find appropriate CF-root kernel

Hi everyone,
First off I apologize if this is too stupid, but I am a complete newbie at this (yes, I watched the noob video before registering).
I rooted my galaxy s2 GT-I9100 using the Odin insecure kernel --> S2 root --> Odin secure kernel method. Then i installed CWM Rom manager. However it says that I do not have CWM Recovery on the phone, I cannot flash the ROM. So I downloaded recovery-clockwork-4.0.1.5-galaxys2.zip and flashed it to the phone using Odin. It shows PASSED but the phone was stuck at the boot-up screen with the yellow triangle.
I tried to flash the CF-root kernel onto the phone, which many said will solve the problem, however it seems the kernel for this phone "ZSLPE" is very rare (phone purchased in Hong Kong) and I cannot find anything with this particular kernel. Also, when I connect the phone via Odin and try to flash anything, it now gets stuck at "setting up connection", so i suppose even if i find the right kernel, it cannot be loaded onto the phone. Please help! I will be eternally grateful.

Download .tar (Odin version) version of Siyah kernel here: www.gokhanmoral.com/gm/2012/07/29/siyahkernel-s2-v3-5/
Flash the kernel via Odin.
Ps: asking questions, or even searching could have saved you all these mess because, ROOTING ICS doesn't really require flashing any kernel unlike gingerbread.

If you're on ICS you can flash siyah kernel for S2(the .tar file) and you'll get custom recovery and root at the same time. Kernel are usually universal you don't need to find the specific kernel for your rom. Only if you're using a 4.0.4 rom you have to use a 4.0.4 kernel same goes for the 4.0.3 because you're going to have bugs with the camera etc

I exited Kies, so yes I don't think it's running. Plus Odin was able to flash the CWM recovery onto the phone right before it got stuck at the yellow sign. After that it stopped working.
Should I flash the latest version of Siyah (v4.1.4) instead of the one you suggested?
Thanks again

I9100 freezes at samsung logo screen

First, I want to say sorry because this question has been asked many times. Though I have done searches on the Internet and came across some solutions, I still don't understand how to solve it.
Anyway, here's the story: my brother just bought a galaxy S2 (I9100) and decided to root it via ODIN. However, he mistakenly flashed his phone with a firmware for I9100G. He then tried to flash again with a custom kernel for I9100, but the phone always freezes at the startup screen (with that yellow triangle). So that's 2 custom kernel at the same time.Then I tried to flash the phone with a stock kernel. This time, there is no yellow triangle at the startup screen, but the phone still freezes there. I can still access to the Recovery and Download mode, but have no idea what to do next. Please help me. Thank you
If you can access Recovery, try to wipe data/cache and Dalvik cache. And try flashing a custom kernel after that with the compatible zip file through recovery. I recommend Siyah.
But don't do this with 4.0.4 stock recovery, cause then you will be bricked.
Cheers.

Wait, if I recall correctly, then the phone's version is 4.0.4 before the rooting attempt. So what you mean is that I shouldn't wipe cache with the version 4.0.4 or I shouldn't flash kernel with that version ? Because if it is the latter problem, I can go around and flash through download mode. Anyway, thanks for the advice

You've managed to flash the right official firmware with Odin? Just make sure you don't perform any wipe with stock kernel (in stock recovery) from 4.0.4, all other kernels will be safe.

Yes, I managed to flash the official kernel with ODIN after flashing the 2 custom kernels mentioned.
So, now if I want to wipe, I'll have to re-flash my S2 with a custom kernel right ? assume that works and everything is wiped, will the S2 be able to work again ? Or do I have to do something else ?
Did ur bro make a backup before flashing ?
I had a stuck on logo prob and the only way I could fix it was by loading my backup. wipes or flashing other kernels would not fix for me.
I have read others with similar or boot loop issues caused by kernel and fixed the same way.
if u don't have a backup I don't know, maybe research soft brick fixes. good luck.
peace
Just flash official firmware through Odin. No need to restore back ups or flashing other kernels.
Afterwards root it again and flash a custom rom.

[Q] Samsung Galaxy S2 - Won't boot

I rooted my SGS2 yesterday and today when I woke up I say the app "SuperSU" with a new icon.
I "clicked" on it and it said something about ... that it will boot into CWM and do something.
It restarted and since then my phone has been unable to boot.
The phone is using "Jeboo" kernel.
Any ideas about how to fix this? Flashing a new kernel?
I am able to get into download mode, but not CWM.

Exactly the same thing (word by word) just happen to me! have you found a solution?
Flash stock firmware with Odin. About all you can do as phone wont boot into cwm
boot recovery
After flash stock firmware with Odin everything go back to normal.
Installed SuperSu again but when it ask for update the binarys choose the NORMAL option not the CWM one
Are you looking for root? What firmware are you on now?
