I recently purchased a Samsung Galaxy SII, GT-I9100 and have been trying to install LineageOS using this guide:
https://wiki.lineageos.org/devices/i9100/install
I'm at the point where I need to flash TWRP. I've downloaded TWRP 3.2.3.0 and using Heimdall, I'm able to successfully flash the image to my phone, Heimdall's output doesn't mention any errors. However, when I afterwards shut down the phone and then reboot to recovery mode, it's still the old stock recovery present.
I have spent the entire weekend trying to troubleshoot a ton of things and trying many suggested solutions, some not working, others throwing me further down the pit of despair. One of the things I've tried was to flash CF Root. My build number ends in KWMS2, so I've been trying to find a CF root build for that but the only thing I found was this post:
https://forum.xda-developers.com/galaxy-s2/help/cf-root-download-ms2-t2880023
Which then had a link to SuperSU which I sideloaded with adb, but that didn't do anything. I also found this post:
https://forum.xda-developers.com/showpost.php?p=35682278&postcount=4
And flash the CF Root image, but that also didn't help with TWRP. I've also looked at the CF Root site but it doesn't list the GT-I9100 and Firmware.Mobi lists all i9100 versions as incompatible with CF-Auto-Root (which I'm assuming is the same as CF Root).
So because of all the trouble I've had, I'm now stuck with a phone that can boot into download and recovery mode, but can't actually boot into Android and that won't install TWRP for some odd reason.
I hope someone can tell me, in detail, what I'm supposed to do to get TWRP to actually work and not just being flashed, because I'm at my wits end.
Follow this guide (the post literally one below yours!) and you will be up and running in no time.

I know this forum emphasizes a lot on obviously finding other threads which will likely have the answer to your questions, however everything I've looked at so far has a similar problem, but not entirely the same or the solution for them doesn't work for me. So do forgive if this is something ridiculously simple, I am new to rooting!
So I'm on a Galaxy S2 running Gingerbread 2.3.4, my baseband version is I9100XXKI1 and my kernel version is [email protected] #2
Using Odin3 v1.85 and S2 Root. (Superoneclick kept freezing on me)
My aim is to install Cyanogenmod 7.1.
So far I started off by trying to flash it with XWKDD Insecure, which I believe is wrong? However after rooting it, I installed ClockworkMod Recovery, downloaded the ROM and tried installing it - which is where the problem started - I kept getting the error in recovery mode 'Invalid whole-file signature'.
It just wouldn't boot in to ClockworkMod Recovery.
So after some digging around I managed to find a file to flash to my device for the CWM Recovery mode, tried it, and it worked. However, I still couldn't install Cyanogenmod from my SDcard.
I tried it a few times, wiped/formatted a few times and ended up getting my device stuck in a bootloop.
So, I've managed to get it out of the boot loop, and started fresh...
I flashed it with XWKH4 Insecure, unrooted, rerooted etc.
I've downloaded CWM again, downloaded the Cyanogenmod again, tried installing it, and once again it's gone back into Androids recovery and failed to install because of the 'whole-file signature' and failing to verify it.
Any help would be extremely appreciated, sorry it's a bit of a long read,
Thanks in advance!

I've been searching all over the forums for hours and I can't seem to get a viable solution to my problem. Here's what happened:
New Samsung Galaxy S2 AT&T
I used the cyanogenmod wiki site to flash clockworkMod recovery:
not realizing that there was a separate page specifically for the S2 for AT&T....so end result is ClockworkMod recovery 4.0.1.4 instead of 5.0.2.3 using Heimdall suite. I don't know if this makes a difference
So with reboot my back and search buttons wouldn't work so I did a factory reset, now I'm stuck in boot loop
Went into CWM recovery, did clean wipe, but it won't let me flash any zip files (gives "no file or directory" error and installation aborted)
I never flashed any ROM's, just the CWM recovery
I don't know what to do. Please help.
I apologize if this is answered elsewhere, but I made an honest effort to search for it.
just follow this thread...http://forum.xda-developers.com/showthread.php?t=1309301 and flash 3 .tar files in odin...
Thanks for the reply zking. I actually saw that thread but wasn't sure if it was applicable. I'm a little confused. I've flashed CWM recovery before on other phones (G1 and G2) without any problems, but those required that I rooted them as well. The cyanogenmod site for the SII seemed (at least to me) to have indicated that root may not be necessary to flash a ROM. Is this true or am I just misinterpreting?
So as it stands, my phone is not rooted. Can this be reason I'm having a problem with CWM recovery? It's not giving me a mounting error, just says file doesn't exist, when I know it's there. Is it looking for .tar format?
and when you say flash 3 .tar files in odin....which files are you referring to (may be dumb question)
First flashed the required firmware from here http://forum.xda-developers.com/showthread.php?t=1075278
than root accordingly as mentioned here http://forum.xda-developers.com/showthread.php?t=1126522
after rooting as per the above method you ll have CWM recovery installed...and you can start using it accordingly.
Don't listen to zking. He's getting you to flash more wrong firmware to your phone. Go to the AT&T forum and download the correct cwm from there. The AT&T version of the phone doesn't work with I9100 firmware.

Hi, I'm following the instructions on ChainFire thread in the following link
http://forum.xda-developers.com/showthread.php?t=1695238
To root Samsung Galaxy S3 without flashing unsecure kernel.
This method, as I understand should flash the Clockwork and install SU.
So far I've flashed it like 4 times, it wont install superuser.
I've seen multiples videos, where after rebooting, it will show the linux like console and install SU, and what now, mine is not doing that. It will just boot Android and no SU.
In the About phone, it shows "Modified", and if I boot in recovery, I'm able to access ClockworkdMod, but so far no luck with SU.
Am I missing something?
My phone is I9300 plain, and I updated after I got it new, shows build number IMM76D.I9300UBALF3
I'm running an international version, which I'm not sure if its the same as the European version used in the toolkit, hence I didnt want to risk it flashing the insecure kernel that comes with that toolkit.
I've tried booting in CWM and try to just flash the SU zip that comes with
CWM-SuperSU-v0.92.zip
and the one from the toolkit 2.0 (think its SU 3.0.7 or something), both will fail the signature check thing and wont install.
Any suggestions?
Thanks in advanced.
Hello,
I recently made some mistakes with my Galaxy S2 GT-i9100 while following this a tutorial on Galaxys2root.com (Can't link to the precise article because this is my first post) I flashed the CWM recovery tool linked by this website to my device through the latest version of Odin and afterwards my phone would not turn on. I was able to get into the Clockwork recovery mode however but couldnt install anything because I had forgotten to place any ROMS on my device beforehand. To try and resolve the problem I did a factory reset in the recovery mode but this did not effect anything. I am now unsure what to do next. I would still like to root my phone so that I cant get rid of all the bloatware put on it by Orange mobile as well as update my phone to Kitkat(Currently running Android 2.2) Can someone tell me what I have done wrong and what is the next step for me to take?
Thank you for any help that you can offer
the kernel you flashed it is the problem

is this site you are talking about:
http://galaxys2root.com/cwmtwrp-recovery
im guessing that is the problem(Installing CWM/TWRP recovery will most likely break the ROM you are running currently as it overwrites the ROM’s KERNEL).
If iam right,that means you have to flash another kernel,i suggest Siyah kernel 2.6.14 its for gingerbread version(it has CWM recovery and auto-root):
http://forum.xda-developers.com/showthread.php?t=1263838
after that you can flash the KK rom you want through CWM .
Hello. I have a stock S2 S959G that hasn't been rooted and am interested in installing my 1st ROM. I have read Mr.Cook's thread (http://forum.xda-developers.com/showthread.php?t=1982571), I feel pretty confident in trying to root my phone. However, after reading other threads on xda, I am under the impression that I don't need to even root my phone when installing newer ROMs. Instead all I need to do is install TWRP recovery, download ROM, compatible gapps, and I'm good to flash?
I know its not that simple and any step by step instructions on how to flash the latest the newest TWRP, ROM, and gapps available for my phone would be greatly appreciated. Apologies in advance for being the newest of noobs.
*Edit: I was successful in installing TWRP 2.7.1.0 found in Mr.Cooks link. Still no success with the zip file for the 2.8.7.0v.*
I found (what I believe is the latest recovery for my phone) TWRP 2.8.7.0 in this thread http://forum.xda-developers.com/galaxy-s2-att/development/mtp-twrp-2-8-7-0-i777-s959g-t3212309
Of course the TWRP found in this thread is a .zip file and odin doesn't recognize .zip files. I read on how to change it .tar or other usable file but it seems that you need a Linux machine.
I also tried the download twrp link in Mr. Cook's thread I linked in the OP. Unfortunately when I tried to download to the phone in ODIN it tells me the MP5 is invalid. I tried it again and it said complete write failed. Could it be the version of ODIN I am using is to outdated (1.85)?
*Edit: Found the answer to ODIN failing due to complete write in this thread: http://forum.xda-developers.com/galaxy-s2/help/solved-help-completewrite-operation-t1157231*
Again any help provided would be greatly appreciated.
