Hey everyone. I decided to revive my S2 but I ran into a problem and I can't solve it. I lost count of threads I read and I still don't have an answer. Can someone guide me step by step how to flash CWM and ROM to my SGS2 (i9100)?
At the moment I have stock ROM flashed using Odin since all my tries to flash latest CWM and ROM ended in a bootloop or I didn't even manage to flash anything. If I try to flash CWM through stock Android recovery, it says "Signature verification failed". I flashed Dorimanx kernel using Odin to get the recovery but then I couldn't flash ROM because it said "E: Can't mount sd card". I tried flashing Resurrection Remix ROM.
I have no idea what to do because everytime I think something new, I run into these 2 errors. It would be great to get some help.

I downloaded the kernel from here: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/i9100 but I get this error: E:Error in /tmp/sideload/package.zip (Status 7). Above this, in the yellow font, it says This pacakge is for galaxys2, i9100, GT-I9100, GT-I9100M, GT-I9100P, GT-I9100T, SC-02C', devides: this is a ' '. How can I fix this?

Kernel not just recovery.
I think you need to read the thread before flashing away and possible bricking you're phone.
Rooting and installing cwm is basic stuff. Bricking is common place too.

Do you mean this http://goo.im/devs/philz_touch/CWM_Advanced_Edition/i9100/Stock (Download doesn't work) ? I can't find any other links there for the latest version.
I'm not really scared of bricking my phone since I won't use it without flashing it correctly anyway. I have flashed it few times successfully in the past but now I can;t do this and it's really annoying. I flashed my friend's phone without any problems but I can't do that for myself.

Hello ... I ask you a little help on ROM Manager and Recovery.
I just root the galaxy S2 with the procedure supercurio, so my ROM is pretty much stock ... I was a XWKDD.
ROM Manager (in his opinion) regularly install ClockworkMod 4.0.0.2, but when I restart in recovery and launch the update.zip I get the following error message:
Finding update package ...
Opening update package ...
Verifiyng update package ...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted
Googling a little I found how to sign files.zip, moddied 3e recovery and also to ignore the signs in zip files ... but none of these workarounds work ...
So how I can use this 3e recovery with unsigned files?
Or ... how can I replace the 3e with the 2e recovery? (There ROM with the 2e which do not differ much from the stock ROM?)
recovery 4 you are using old methods .

Help needed aswell
EDIT: I do not like the CWM4 as the recovery deletes it's self after about a day for some reason, then i have to reflash.
I am using the Stock XWKF4 rom (rooted) with superuser and busybox and i also can't use ROM to install clockwork mod recovery.
I get the same error as the guy above me.....Help
Please, Thanks,
Andrew.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Having this problem too.
In ROM Manager, I flashed the latest CWM, then reboot into recovery.
It reboots to Android system recovery (3e).
Any idea how I can get recovery working. Do I need to flash a different kernel?
I actually JUST dealt with this issue myself. I had the same kernel as you.
You need to flash a new stock ROM in odin, I used KG6. I just used the stock kernel, not the whole package.
The stock ROMs can be found here :
http://forum.xda-developers.com/showthread.php?t=1075278
Then when this is done, you use odin to flash a CF Root for that kernal following these instructions:

I am also having issues. I have an SGS2 with 2.3.3..
I have rooted the phone and am trying to install Cyanogenmod7 (nightly build #22) to my phone.
I have downloaded ROM Manager, Flashed Clockwork Mod Recovery (4.0.1.5) and have tried to 'Install ROM from SD Card', then selected the cyanogenmod. However, its coming up with the following message:
Finding update package ...
Opening update package ...
Verifiyng update package ...

I have tried to download 3e without signature verification "3e_recovery_no_sig_check" but this has not worked. I am a bit of a noob at this so appreciate any lamens terms help anyone can provide!!
Hey guys. I tried the KG6 and CF kernel, and the lulz kernal. Both are giving me t 3e error on CWM. What else can I do?
cant flash roms
Hey guys,
I too am having this problem. I have completely lost the ability to flash roms from cwm. It says "Installing update" when its a new rom and it flashes it in less that 3 seconds and then it gets stuck at the boot. If I use rom manager it just says "E: signature verification failed on the whole file". I have tried the following:
-restoring stock rom (KE2) and then using cf-root which installs 4.0 and cwm 4.0.0.2
-formatting sdcard
It's really bad, I am dwelling on just one nandroid backup of Cognition and I can't even update it!
Thanks for your help
You cannot use 3e to install custom roms. 3e (blue color) is the default samsung recovery. When you try to flash custom rom with 3e, it will fail verification.
You need to use Clockwork Recovery (orange color).
Try installing Speedmod Kernel instead of using CF-Root kernel and see what happens.
Mate that totally fixed it thanks so much for the help! Now I can get back to flashing stuff!!

Problem to flash CWM
Hi,
Here are the steps that got me into this situation:
1. My provider installed a test version on my Galaxy S2 in order to resolve some problems.
2. After the above I rooted my device using ODIN 1.85 and SuperOneClick 2.1.1 using XWKDD kernel.
The versions of my phone now are:
Model Number GT-I9100T
Android version 2.3.4
Baseband version I9100TJIKI1
Kernel version 2.6.35.7-I9100XWKDD-CL161513 [email protected]#2
Build Number GINGERBREAD.JIKI2
My intention is to flash CWM in order to install Cyanogenmod ROM. When I tried to flash the CWM using ROM Manager it failed. From what I read it is because I have 3e recovery.
I saw some suggestions for resolution, like flashing a stock kernel and than flash CWM again to avoid the invalid signature problem.
However, I couldn't find any kernel that fits my device situation.
Any suggestions for a route I can take to resolve the situation?
a route that will leave my device functioning
Thanks, Nissim
You should try and install a custom kernel which also flashes clockwork mod recovery on your phine like speedmod, ninphetamine or hellcat's kernel.

Thank you for the advise.
Unfortunately digging into the above kernels you suggested, I couldn't find that any of them fits my situation (Build:GINGERBREAD.JIKI2 and kernel:XWKDD).
I saw clear warnings not to select the wrong kernel.
Look for cfroot kernel. It is almost stock. Just rooted. I think i saw ki2 over there.

so, I've had my SG2 for like a month now, rooted and all, but the problem is , i can't flash any other ROMs(but stock ROMs) or kernels (except for CF root,stock and siyah kernels ) on it via CMW... each time i tried to flash anything, i end up stuck at "galaxy s2 GT-I9100" boot-up logo.... I've tried flashing CM7 then i got the boot-loop ( even with double flash, or triple didn't work for me) and i can't get into CWM when i got the boot-loop....
someone please help me.. i read alotta threads and none of them got similar issue like mine...
i guess its true what they say : every galaxy s2 is different from the rest.
Hmm....must be something you're doing wrong. Nothing to do with Galaxy S2 being different.
Have you always followed the dev's instructions while flashing roms?
Wiping data, cache? Matching up the kernels and roms?
As far as I know, there hasn't been a single person who completely failed to install VillainROM on their SGS2.
I would advise you to give it a go.

What ROMs have you tried to flash?
If you're tring to flash AOSP ROms like CM7 or MIUI it's normal if you're not doing it with a comatible version of CWM. For example, cf root kernel installs a modified version of CWM on your device, which is not compatible with CM7. IF you want to flash CM7 first you have to flash codeworkx kernel http://forum.xda-developers.com/showthread.php?t=1118693, and then enter recovery (the new CWM installed with this kernel) to flash CM7.
Now if you can't flash samsung firmware based ROMs (villainROM, Leomar Revolution, Batista...), I don't know what it could be. I never had a problem flashing samsung firmware custom ROMs with the cf root CWM recovery.

If your phone has cf-root/kernal and cf cwm can you just flash over top codeworkx's kernel and do you have to re-root?

My phone came with CM7, but i flashed it with rooted stock coz i wanted to have a feel of it... but now i'm done with it but i can't get any roms to work... so frustrating.
i literally have tried flashing ALL Roms (ligtnung, gingerbread,vr, cm7), during the 1st few days that i got my phone it worked with VR 2.5 and 3.0, even MIUI.. but after i flashed with some Asian stock ROM via odin... nothing would work through cmw anymore...
i seriously don't know what i did wrong...
btw, right now im using basebad ver: I9100XXXKI4, kernel: 2.6.35.7-siyah [email protected]#20, build number GINGERBREAD.ZSKI3.
I really don't know. YOu should try to go the closest possible to stock and try from there. DO a full wipe, wipe data, wipe system, everything and flash a stock ROM from your country and carrier (there is a thread from infratech where you can get carrier specific ROMS). THen connect your phone to kies (maybe yo get an oficial update) and then do everything from scratch, root, install CWM, etc...
That's what I'd do but I really don't now if it's the best option.
i have almost the same problem,but me i can flash any rom,but the problem is with the kernel my phone refuse to boot on any other kernel else than cf-root and the speedmod,it freezes in the kernel loading so i must turn it off and reflash via odin cf-root or speedmod to get it works again.

Phew! NOW I HAVE CM7 RUNNING ON MY PHONE!!
I'm gonna try to explain how i fixed my issue, as clear and explanatory as i can..
lucky i didn't brick my phone during all this, because I tried so many things and none worked.I unsuccessfully tried downgrading to XWkI4, ZCKI4, and alot others via Odin... after flashing all i get is tons of error messages(on 3e recorvery) E: can't open/cache or E:failed blah bla bla to load /efs... i thought OMG! my phone is bricked! then i recalled reading somewhere that flashing the 3 tar (PDA,MODEM,CSC) files usually should work(maybe better than flashing a 1 tar file), so i found a 3 files xxKI3 rom, flashed it and BAM! it booted up this time without any error. so now i went ahead and rooted it since the tar files came unrooted, then went into CWM to flash cm7 ROM, flashed it twice and ofc i got stuck on boot logo.....i didn't panic much, i pulled out the battery, and restarted to CWM where i cleared cache/ dalvik/ and did wipe/factory reset, then i reflashed CM7 again (twice) and it worked!!!! YES, CM7 is fiannly working on my SG2!
thanks for everyone for helping, and i hope this can help others on the same boat as me..
Ok, because I was so happy with cyanogenmod on my galaxy s I decided to try to install it on my SII.
Silly me, I decided to follow the instructions. couldn't get my trusty odin working, even after a couple of reboots and reinstalls of kies. Heimdall turned out to be the 64 bit version so I needed to find the 32 bit version. Long story short, the instructions sucked...
Then, I tried to install the suggested cwm. After a reboot, my phone entered a bootloop. I could enter recovery but trying to flash cm10 gave me "Status 7 blabla".
So, I searched on the web for a stock rom to at least get my s2 working again, found one and flashed it. Market keeps on crashing and it's version 4.0.3.
I tried reflashing cwm, cf-root and time and time again it kept creating a bootloop after which I had to reflash the rom with the broken market to get everything working again.
My questions are:
where did I go wrong in flashing cwm? Is there a different version I should flash? what's up with the extremely bad cyanogenmod instructions? Can someone get the market working again?
can someone guide me step by step through the process?

because it gives the error "status 7"
I can't install a cwm that doesn't bootloop (I can however enter recovery) and in recovery I can't flash a thing because it throws errors at me
Assuming that you are on stock samsung ICS ROM, flash Siyah kernel from Odin
http://d-h.st/Bcf
After this you will get CWM recovery from which you can flash any i9100 CM version.

quick follow-up:
I had another laptop laying around that was never poisoned by samsung kies, so I decided to give it a try. installed the usb-drivers and used odin to flash another stock-rom version (that actually worked this time )
Then, I flashed cf-root and upgraded to cyanogenmod without any problem.

Hello all,
First of all I want to say I'm pretty new to flashing ROMs etc.
Currently I'm at stock 4.3 Jellybean and I want to flash my SGS3 to the new CM 11 ROM.
I rooted my phone following this tutorial: vvvvvv.telefoonrooten.nl/samsung/samsung-galaxy-s3-root/ (sorry if its in Dutch, but it uses the CF-Root-SGS3-v6.3 and Odin).
After I rooted I copied both the CM11 ROM and GAPPS to my external SD, I went to recovery and tried to install the new custom ROM but I got an error (status 7) and it was aborted.
Also if I try to reboot it won't boot normally as it should be but it goes back to recovery mode automatically...
I fixed to get back to Jellybean by flashing the stock rom (unrooting?) it via Odin.
Anyone else got the exact same problem as I do and knows a solution to be able to flash CM 11?
Thanks in advance,
Steelbear

Since you went back to stock and you already know how to root, I suggest you go to Play Store and download ROM Manager to help you install latest CWM recovery on your device.
Or you can simply go to CWM website, pick the version of the recovery for your phone and flash it via Odin.
Hope it helps.

Indeed it worked! I found it out myself yesterday. Went to the CWM site and downloaded the latest version (6.0.4.4.) and flashed it through Odin. But thanks for your input anyways (to all who replied) !
An alternative solution that I often use is to open the Updater Script in META-INF folder in the ROM's zip and delete first lines, where it gets device model as property.
Obviously it's an UNSAFE operation (because that lines avoid to install ROMs of other phone on mine) but when I'm sure that ROM I've downloaded is for my phone I do it and it works
Hello everyone,
I recently picked up a couple GS2's for dirt cheap just to mess around with. I am having a very hard time getting any custom recovery installed on them and I was wondering if there is a trick to it that I am not seeing. I've tried flashing various CWM modified kernels using odin with no luck. They flash successfully but still boot to 3e when I boot into recovery. I tried flashing a modified update.zip from the CM website and it fails with the error "failed to verify whole-file signature". Most recently I did a complete restore using odin with a rooted image, then used Rom manager to install CWM. Rom managed says it is successful, but when I reboot into recovery it launches 3e and attempts to do something that returns the same error "failed to verify whole-file signature". Any input of suggestions would be appreciated.

The recovery is compiled into the kernel on this phone, but it seems that you understand that already. The kernel and system must match. You probably need to be rooted. You have not given any specifics about the firmware, what is already installed, what specific item you are trying to install, etc.

This does not actually seem logical. I'm wondering if you are not mentioning something that I would need to know to determine why you are getting this result. If you install a custom kernel containing a custom recovery, you should then be able to boot into the custom recovery. If you still have 3e recovery, it indicates that you still have the stock kernel installed.

I would not expect that to be successful. Among other things, it is probably not specific for the I777.

Do not use Rom manager. It does not work with the I777, and can cause unrecoverable damage in some cases. There is a sticky post about it here in the forums.
You can find various resources in the Download Repository. See the link in my signature.
Here's what I would do:
Flash the latest stock Jellybean firmware, UCMD8, from the Repository.
Root using Framaroot with the Aragorn exploit.
Flash the AJK v4.9 NoSwap kernel using Mobile Odin Pro or Mobile Odin Lite. You have to extract the boot.img from the kernel zip and flash that, but don't let it boot into system. Instead, you can boot directly into CWM and flash the AJK v 4.9 NoSwap kernel zip, or if you prefer, you can flash some other custom firmware at this point.

Sorry if I want clear. The phones are currently on 2.3.6. I tried using framaroot but it was not successful. The app said it was successful, but there was no supersu after I rebooted. I successfully got the phone rooted using one of the one-click odin flashers posted on these forums that are said to return it to factory + root. I then tried to use rom manager which said it was successful, but wasn't. That makes sense now that you're telling me its not compatible. Ill try upgrading to the JB firmware first, then ill try framaroot. Thanks for the suggestion
I just wanted to update the thread and say that this worked. Thanks again. I'm having an issue getting Gapps flashed but that's another topic. My big concern was that the phones wouldn't charge without boot looping because they had the wrong battery installed. The Stock Jellybean with the kernel you suggested fixed that.
