[root][twrp] need an up-to-date guide - Galaxy S II Q&A, Help & Troubleshooting

I owned an i9100 back in the days, had some fun with it, but then it died. Now i got in possesion of another i9100 and can't seem to find anything i remember doing, like rooting and flashing recovery via odin. Also there are some dead links and things i cannot understand in guides i've seen. I did not quite focuse on them, just took a look, but there was nothing like "flash this and that via odin".
I've seem something called heimdall(?) in the twrp 3.3.x.x guide (is that the alternative to odin?)
The S2 is running on lastest stock JB. How do i get it rooted and flash recovery?

Which CWM Recovery for 3.2 root?

Hey all - before I start I do want to say that I've watched the noob video and I have searched endlessly for days...I'm finding bits and pieces of valuable infomation that have prevented me from making some serious mistakes and I'm eternally grateful for that. I'm also seeing great root guides for my P7510 that I will follow once I am certain that I am in a good spot with my device.
That said....
I want to simply root my P7510 (3.1 updated OTA to 3.2 right out of the box, 2.6.36.3, P7510VLKL2) for now...no custom ROMs just yet, but I do want the ability to do it. So, I followed the guides in various places to obtain the Recovery.tar.md5 for CWM 5.5.0.4 (saw it was recommended to use the latest to flash the 4.1 JB ROM..thought what the hell) and flashed it with Odin 1.85.
Rolling recovery screen. I squinted...hard...and was actually able to take a NANDroid backup which I'm planning to move off of the device and onto my PC for safe keeping. After that however, I determined that trying to read the screen and go further would make my brain blow up and I should try to fix the screen issue first.
Rebooted, no problem. I rooked out major after that thinking "oh, well OK CWM doesn't like me so let's flash TWRP and that will make it all better". Yeah right, that made things WAY fun as I spent 2 hours poking at my rolling screen trying to figure out where the buttons actually are to reboot the device without destroying something.
So I've re-flashed CWM 5.5.0.4 because even while it still rolls, I can at least read it - but I'm gunshy to try anything now because I can't read the thing. I've seen threads about trying to unlock the bootloader but other threads say it isn't necessary. I've seen threads about flashing stock ROMs with Odin but have heard absolute horror stories about people flashing what they thought were stock ROMs and making things worse.
I've searched for this answer everywhere and can't get any help...so, powers that be, if I may draw upon your infinite wisdom, please enlighten me...is it feasible to root my HC3.2 P7510 (purchased in Canada) using the root package that you can find anywhere on an OLDER version of CWM? Will ALL versions of CWM roll my screen like this or just 5.5.0.4? Do I even need 5.5.0.4 if I'm not trying to flash the alpha 4.1 ROM?
Thanks in advance for any help you all can provide in consolidating all the great related info in this forum into one place...

[Q] I think i may have messed up a Galaxy S II i9100

So...
I was asked to root a Samsung Galaxy S II i9100 the other day...
I got the person to back up all of their stuff through Kies and then they bought the phone back to me to try and root.
(Why do they want to root it? To remove the noise on the camera when capturing video - I believe this will help narrow down which version it is..)
I managed to download and install a Siyah version, through Odin, and i have the CWM recovery mode, and also the Download mode available.
When i boot up the phone, it comes up to the Yellow triangle image, and no further...
I thought it was a pretty simple task, clearly i have messed up and not realised the extent of the process - i am clearly missing something out - or downloading the wrong things... Should i be downloading a different version - i can't find what files i should have already - and i don't know how i would be able to download apps to the phone now it's only on recovery mode...
I understand everyone asks these and you direct them to other previous threads, but i've doubted myself on everything i've done up to now, so could anyone clarify the correct steps i should be taking?
I believe the phone was on 2.3.3 before my attempted root, but i don't personally have any other details of the phone....
I don't even mind if i can't root it, but if i could possibly revert it back to stock i would be equally happy as we currently have an unusable phone.. (I don't think it's bricked is it?)
Thanks in advance,
Tom.

If you are still able to access cwm and download mode I am pretty sure that you are not bricked(but still there is always a small probability) so I recommend you flash a stock rom via Odin, read lots because I have read of an old siyah kernel which has the brick bug, be careful with ics stock as well.
For all the above recommended matters there are hundreds of threads with extensive details.
For Rooting read several threads and choose the easiest method.

Somebody correct me if I'm wrong, but as far as I know, the kernel you flashed ( siyah ) is not compatible with gingerbread....
So as another poster commented, flashing a firmware in Odin will be the easiest way to recover. Then you can try rooting again....
But do your research first....
Afaik. ...rooting methods for gingerbread are "not prolific". It might be advisable to flash 4.0.3 ics or 4.1.2 jellybean and then root that........

Why did you not advice him to update his phone????? You went through all that trouble of using KIES to backup and you didn't update the phone?
A firmeware update might have already solved his problems.
And how could you not read that the flashed Kernel does not support such an old Android version. Rooting has a possibility to cause your phone harm, so it should come naturally that you inform yourself on the topic and double check everything in order to minimze the risks.
I am really sorry for what I wrote, but I just can't understand such a mentality!

Help a Hopeless, Please!

Where to start? Well we can start by saying that I am a fool. I won from my uncle his Galaxy S2 (GT-i9100), but wanted to upgrade to version 4.2. It is a phone bought in Latin America branded by Claro. He had UHKI4 Kernel and system android 2.3.4 (if I remember correctly). So I rooted the device using the method of Odin3 v1.85 with CF-Root-Kernel-v4.1-SGS2_UH_MUL_KG7 CWM4. The root was ok!
I went into recovery mode and tried to follow the steps of this video /watch?v=ezuW5qFS8-w. I used the I9100VJMS4_I9100ZTAMS4_ZTA rom. But something went wrong and my phone is stuck in recovery mode CWC. Cant boot, I dont know how to flash anyhing...I need help, I wonder if it is possible to recover the phone yet and if possible put the kernel back and remove the root ... summarizing back to the original.
I appreciate if any help was as detailed as possible. And thank since now everyone who read the topic. Sorry for english errors
Well I am hopeless :crying:
Well I managed to restore a backup :fingers-crossed:, I'm actually pretty dumb . I downloaded a firmware instead of a ROM (you can laugh now) . :laugh:
But I still doubt. Let's think in two hypothetical situations below:
1 - I would like to upgrade from version 2.3.4 to 4.0 or 4.2. And put a custom ROM or Stock
2 - I would go back to the original kernel and unroot.
How to proceed in each case?
Glad you got it working again. Now that you have it working and not in such a panic, you should do some reading. Someone telling you how to do things like that will never work out, you'll always be relying on others to do whatever modifications you are currently attempting. By reading and learning about it, you'll be able to do it all for yourself. So how to proceed in each case? Research & learn about each one. Both are legitimate things to do, and there are plentiful threads/guides on each.

2.use cwm

Well, I could do what I wanted. Thanks for the reply Hopper8. After I calmed down I could organize ideas. And thanks for the detailed answer theunderling lol
No problem....any time

[Q] Cyanogenmod installation

Hiya,
I've got a rooted 4.2.1 Samsung GS3 GT-i9300 network locked to Orange and I want to install cyanogenmod, I know exactly how to
but I'm scared.
I've got a friend (even more nood than I am) he installed Cyanogenmod for GS2 on his S4 (lol) bricked it.
(But I obviously know not to do that )
Anyway,
I'm just scared of the whole idea of bricking the phone.
What would be the worst case scenario of I do everything right?
I have previously installed a custom rom on a tablet, but that only was because I got instructions from the guy next to me.
I know exactly how to install the rom but what could I expect?

The easiest way to ensure nothing goes wrong and to gain confidence is to read, and make sure you understand the procedures you are following (Then go back and re-read, and make sure you really understand the procedure this way you can be confident in yourself ). That being said the first thing you will need to do since you are already rooted is to flash Clockworkmod Recovery on your Galaxy S3 which you will then use to flash Cyanogenmod, a video tutorial on how to flash Clockworkmod Recovery can be found here. Once you have successfully installed Clockworkmod Recovery then you can download Cyanogenmod 10.2 and follow the instructions to install it found in this thread. Make sure you read and re-read everything in that first post in the thread I linked to before you install Cyanogenmod. As far as what could go wrong the likelyhood of you hard-bricking your device is small. Most likely the worst thing that could happen is you could soft-brick the device and need to use Odin to re-flash the stock ROM on your device. Overall there is always risk of bricking your device as that is the nature of modifying devices, but as long as you read, re-read, and re-read again all the instructions and comprehend them you will be fine, confidence my friend you got this :good:. And by all means if you have any further questions please don't hesitate to ask.

[Q] Corrupt Recovery Mode

Hey guys... So I'm REALLY new at this whole rooting thing, so please forgive me if I am not aware of any terms related to rooting and such.
So basically what happened was this:
I decided to root my Galaxy S4 (sgh-i337 --- AT&T) using the towelroot method. I had to use this method because my phone is currently running Android 4.4.4 KitKat (TouchWiz) and it worked fine. SuperSU was installed, Root Checker said my phone was rooted, it was good. I tried to install CWM using Odin, and I got the "RESET" or "PASS" from Odin, which I thought that it meant that it worked. However, when I tried to go into Recovery Mode, it went into Stock Recovery Mode. I started to look at other tutorials, and I came across another one that involved flashing your phone's respective CWM .img file from your phone itself (transfer the .img to your phone's SD, and then flash it from your phone using the app, Flashify). But when I tried to go into Recovery mode to see if it worked, it gave me the yellow triangle with an error message, "System software is unauthorized by AT&T" or something like that. I tried to look at other posts, and there was a general idea that I needed to flash the stock Kernel. Now, the way I rooted the phone in the first place, I already had two different ones downloaded. One was flashed, towelroot was used, and then the second kernel (which was the one that originally on my phone before rooting) was flashed. After that, it was rooted. So me, being the complete noob I am at rooting, decided to re-flash both, in order, to see if that cleared up the error message when trying to get into Recovery Mode. This did not solve the problem either.
Again, I would like to apologize for my lack of knowledge on rooting and such, so please forgive me for my incompetence. And yes, I know that there are other threads on topics like this, but I have tried several things and it has not worked. Any help on how to fix this problem (and how to install CWM properly on my phone - since it is updated to 4.4.4 TouchWiz - or if I should use TWRP instead, because I intend on downloading the Kangapop GPE ROM(and how to install that for my specific model/software version)) is greatly appreciated, thanks!
