Unable to root i9300 on 4.3 (tried everything) - Galaxy S III Q&A, Help & Troubleshooting

Hi
I reccently bought i9300 ( hongkong ) and it came with 4.3, i tried rooting it with CF-Root, The process itself completes with no problem but when i open SuperSu, It asks to update binaries but when i do it fails.
All of the fellow xda helpers have suggested to install CWM and than flash Update SuperSU ***.zip from chainfire, I did that as well ( i flashed the latest zip) But the problem is there.
Can anybody help me with that?
The CF-ROOT and flashable supersu i have flashed are:
UPDATE-SuperSU-v1.91
UPDATE-SuperSU-v1.86
UPDATE-SuperSU-v1.10
CF-Auto-Root-m0-m0xx-gti9300
CF-Root-SGS3-v6.4
Now as i am not rooted so i can't backup the EFS (i don't want to take the risk of loosing my IMEI) and flash stock 4.1.2.
-----------------------------
Here are the details of my phone:
Model no: i9300
Android version: 4.3
Baseband: I9300XXUGNA8
Kernel: 3.0.31-i902166 [email protected]#1
Build no: JSS15J.I9300ZSUBNB1

Thanks

Backup your data.Try to use factoy rom (XXUGMJ9) for odin with pit and repartition.. Flash philz touch recovery and flash lastest update-supersu-v2.01 and should work without error.

i already did a backup through cwm, Is it good enough ? as i have read in the forum that if you dont have efs backup and you flash stock through odin, you may end up with lost imei; That's the boat i don't wana be on ... so i await your response on that.
Also can you guide me or give me a link to PIT and Repartition stuff, as i am new to samsung, i moved from htc.
After flashing stock, philz, do i need to flash cf-root through odin or update-supersu will do the rooting trick?
Thanks for your response

You should only use pit files as a last resort! Use only if your phone is not booting or major problems like that and definitely not because you can't root!
If you flash latest PhilZ there is a option in the settings to fix supersu try that way first or try a different version of su from playstore.

using odin i have installed latest PhilZ recovery, although the superSu is having the similar problem but i was able to find " backup efs" underr custom backup, i think internally my phone is already rooted, as custom recovery went on smooth. Will that efs recovery be enough to bring my phone IMEI back? Can you suggest what else should i backup ?

If done properly then yes also I would also suggest making another backup with PhilZ recovery there is a option in settings to do that ( you can never have too many backups) also if you want you can do a full nandroid backup which will restore your phone to how it was before you flashed anything.(but remember nandroid won't backup efs you have to do that separately)

For any fellow xdaz who are seeking help in the same case as mine, Let me update on what i did and what went wrong (although i am still not upto the rooting part)
so as i was on 4.3 ( I9300XXUGNA8)- The rom won't let me root, whatever i did, and i am talking about clearing cache, dalvik, cf-root, superSU update, clearing all superSU app and reinstalling via market and odin.
Than i thought i would ditch the rom and maybe downgrade ( for me that was the wrong idea )
along the way ( as suggested by " tallman43 " i did install PHILZ and did custom backup of efs and i made around 4-5 backups, Big thanks for the awesome suggestion ....i suggest you do the same, as trust me i later found out that 1-2 backups have corrupted files ( i don't know why).
i also downloaded neat rom and in that Aroma installer (rom installer) there was an option for efs backup as well, so i did that and installed that rom. Rom installed without any problem, root was also working fine, i personally love the rom but i have to give my phone to someone and i was hoping for total stock whereas in neat rom there are tags here and there, i would love to have em but as i said earlier...
i downloaded Stock 4.1.2 (I9300OZSEMK2) -- flashed it, flashed went fine but now i got 0000 as my imei, i tried restoring through philz but nothing happened
i restored previously made backup of my old 4.3 but now the imei was displaying " NULL "
finally i stopped there and searched the forums and read through many similar problems, i downloaded 4.3 (I9300XXUGNA8) from sam mobile , flashed it and voila the imei and network is back.
I am not sure what fixed the imei and why was it giving problems on 4.1.2 but i am happy with the results.
I will update for the rooting part and that would be my next step.

I came across this thread as I am facing the same problem with rooting.
I was on a rooted i9300 and did an upgrade to 4.3 via Kies.
Now when I run through the rooting process using CF method, Odin posted success.
I see inside the console (while flashing cf auto root) that SU binaries are being installed and all. But once the phone reboots, root checker reports phone is not rooted.
I tried a couple of other ways and the closest I got was to see TWRP recovery console once, but once the phone reboots, and I try to go back into recovery - it is still Samsung's recovery console.
Actually all I want is to flash a custom ROM because the phone has been running ridiculously slow. Can I flash it through Odin (under AP) or I have to use a custom recovery like clockwork or TWRP.

If you want only to flash a custom rom then you do not need to root custom roms come already rooted (alot of people make this mistake )..Just flash a custom recovery with Odin then follow the procedure in the stickies to flash a custom rom.

CWM version has changed in the CF-root kernal. Many times the backup done with old CWM is not properly recoverable.
Try wiping the data/cache and dalvik cache and recovering nandroid backup.IF this doesnt work , then Best option would be to get your nandroid backup to PC , format the system , flash a stock ROM,root it and try getting to get the backup working again.
Hope this helps!
I think ICS has a different bootloader to that of GB? If so, flash original bootloader from Intratech thread post #2 with Odin in PDA or Bootloader section:
http://forum.xda-developers.com/showthread.php?t=1075278
Then try restore nan-droid backup again.
Maybe I'm wrong, but you won't hurt anything if you follow his Odin flashing instructions.

Interesting... Ill try some off suggestions later. Just to clarify little more: after boot loop i flash kernel trough ODIN, (syah kernel [same kernel that is in recovery]) and everything works (i boot into previously recover system and all fine...), then going into recovery once again after restoring problem occurs again. So problem is not in CWM as kernel itself contains it...
So, maybe better question would be what part of android system does CWM NOT backup... For example, i now that it does not backup camera firmware... What else? It would be great if this backup/recovery would be more complete (including all software/flash/drivers parts of android system...).
Best regards!
Its simple you require the version of clockwork mode recovery on your phone that you used for the backup to recover .
Caught me out last week and took an age to realize the solution .

Yes, backup was created witth syah 2.6.6 and its CWM version... So, i flashed that kernel trough ODIN, booted CWM and recover- stuck at boot once again...

[Q] Can't re-root after flashing stock ROM [XXEMC2]

Hello all,
About a week ago I ran into a problem with my phone which I thought was a software, which actually turned out to be a hardware issue with my sim card. Cutting a long story short, I flashed the official stock rom with Odin V1.85, and it passed and everything was back to default factory settings.
Having now got my issue fixed, I wanted to re-root my phone, in order to go back to the old ROM I was using [UltimaROM v12]. However after flashing various versions of CWM I cannot get my phone to root. I'm no stranger using Odin, I can usually install a new version of CWM in 30 seconds, but my phone is persistent on not rooting. I can't work out if maybe I've done something wrong, but it doesn't seem to be working.
I've tried running as Admin on W7, but it doesn't make a difference, I'd appreciate if one of you guys could help, as I used the search bar before, but it seems no-one has had this problem before.
Modem: XXEMC2
Kernel: Stock
ROM: Stock
Use TWRP or Philz recovery .

I've tried those too, they don't work either.

The problem is the recoveries will look as if they've installed fine through Odin getting a "passed" flag, but when I go to recovery it's still the default Android recovery. Therefore no root.
What root method are you using?
Chainfire one I believe. You basically install CWM recovery, then install SuperSU from .zip in CWM.
So you have rooted but can't install recovery?
Just flash one with mobile Odin,
Nope, no root yet, because I can't flash SuperSU.zip 'cause I'm still on the default recovery.
Just use the old cf root then update the recovery or use framaroot and flash recovery with mobile Odin
cf-root roots the phone as well as changes the stock recovery to cwm recovery! is this the exact one you flashed? http://forum.xda-developers.com/showthread.php?t=1695238

[Solved][Q] Using temporary cwm to install cyanogenmod ROM

I am aware that this has been asked before but there are conflicting answers withing the threads that I have read.
I am running 4.1.2 WLSW having worked my way through the various jb releases over time. Root has been retained using everroot in mobile odin. The kernel is stock.
Having decided to install a stable release of cyanogenmod (10.1.3) I have been reading around for days to avoid pitfalls or to know what to do should a problem arise.
The only one thing that I am still unsure about is whether it is indeed safe to use a temporary cwm (flashed via stock recovery) to install cyanogenmod. I have downloaded the latest temporary cwn from the rommanager site and it appears to work just fine - I have created a backup without issues so I can get back to where I am now if I don't like or have problems with cyanogenmod.
I was planning to flash [KERNEL] ClockworkMod Recovery 6.0.2.9 from this thread http://forum.xda-developers.com/showthread.php?t=1118693 - but in the last couple of pages in the thread there are users that have had boot failures after flashing it. This is what has lead me to ask the question is it safe to use the temporary cwm?
I am aware that there are other kernels that I could use (Philz/Siyah) but would like to know which cwm is safest/best for the installation of cyanogenmod.
Install philz kernel by flashing in stock recovery and put that zip on ext sd. Stay away from rom manager. Dont use it. When you have philz installed make a nandroid bkup and make sure preload is included too. Also bk up you're efs folder with ktool free from playstore. As you have root get that and bk efs up asap. once you have done a nandroid bkup and done the efs bkup then flash cm. May be good to get a copy of you're modem now too.

I have backed up efs already using ktool and have already made a nandroid backup using temporary cwm - good advice none the less.
I have read that rommanager is problematic with the i9100 so am not planning to use it.
My method of choice to flash Philz would be mobile odin (unless there is some disadvantage by doing it this way?).
Regarding my modem, it is included in the stock firmware so I could flash just the modem from this using mobile odin if I have trouble (I have assumed mobile odin works in cm).
My original question remains however - why not use temporary cwm?
Mobile odin will work on cm. And yes you can flash with temp cwm. Get you're modem from here on xda. Makes no odds how you flash philz Use odin or recovery its up to you.

If I can flash with temp cwm, there is no need to flash philz at all - or have I missed something?
If you flash with temp there's no guarantee. Philz then flash is a safer way of doing things.

Presumably the latest Siyah kernel will also do?
Yes that's ok
It's simply a matter of preference.....temporary CWM is as it 'says on the tin'........temporary....
You have to reflash it every time you want to use it.
PhilZ is permanent....once it's flashed, it's there, no further action needed, plus it has a touch interface unlike regular CWM......
If you intend to stay with stock, but want to have the advantages of CWM, then I'd advise go with PhilZ...purely because a few steps less are necessary to be able to use it.......
(Enter stock recovery, flash CWM then use CWM to flash whatever..... every time with temporary CWM)
If you intend to flash a custom ROM, it'll come with its own permanent CWM anyway (which will overwrite the PhilZ kernel and/or remove the need to continuously reflash the temporary CWM)

Thanks for the advice folks. I flashed Siyah then installed cm 10.1.3 and the associated gapps. All went without a hitch. I was actually surprised how quickly the process completed. I had the rotating cm boot image less than 2 minutes after starting the install from first zip.
Off topic, but I am totally impressed with the cm ROM. I find my frustration at constantly waiting for phone manufacturers to catch up with vanilla android releases has completely melted away.
Glad it's sorted :thumbup:

Download HC ktool from the market, create your efs backup with it and use a root explorer to copy it to an external removable micro SD card......

For rooting I will use Framaroot.
For installing CWM I believe that you can install it via ROM Manager, or you can install the ROM directly via Mobile Odin.
Sent from my GT-I9100 using Tapatalk
OK....first....
Why look elsewhere for rooting methods? Everything you need is right here on XDA.
Second.....NEVER use ROM manager on an S2.....it breaks things.
Third....mobile Odin can only be used on rooted devices....primarily for flashing stock firmwares.
What version of android is on your S2....GB, ICS or JB?
This might be my S2, or it might be my W...but it's definitely CM
Yes, I found Framaroot here and am planning to use it for the rooting purposes.
Thanks, good to know. So I will need to install CWM manually I guess. Somehow.
What is it that Mobile Odin does, is it an actual reovery ROM itself or does it install CWM which in turn installs the ROM?
But I can use Mobile Odin to install a custom ROM I think?
I am 4.1.2 JB
Sent from my GT-I9100 using Tapatalk
Mobile Odin is a phone based version of PC Odin.....it is designed to flash back to stock from a rooted modified phone without the need to hook the phone to a PC....
You're on 4.1.2.....
Search for the PhilZ thread.......
With the downloads contained, you can root and flash CWM via the stock recovery in one flash.....don't get much easier than that.......
This might be my S2, or it might be my W...but it's definitely CM
I can root it and flash it in one step? I've found like 50 guides but none of them as simple as you're suggesting.
There are so many ways to do each individual step.
I reckon the steps after that would be to install my custom ROM via CWM via SD card. Clear/Wipe cache and install the custom ROM again?
Sent from my GT-I9100 using Tapatalk
Edit: How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
As I said........easy.....
1) flash PhilZ via stock recovery to root and flash CWM
2) At this stage your phone will still boot normally and allow you to download HC ktool in order to make your EFS backup. It might be an idea to make a full backup (nandroid backup) of your current setup using CWM too....
3) use CWM to flash the ROM (and it's associated gapps package) of your choice.
4) use CWM to perform the cache, dalvik and data wipes.
5) reboot, perform initial setup download user apps.......
Job done.......
This might be my S2, or it might be my W...but it's definitely CM
You could also juse Siyah Kernel, a good alternative to philz:good:
Except that it can't be flashed via the stock recovery.....it has to be flashed via Odin......

In which way does a Kernel replace a rooter/bootloader flasher, are these not different things?

I very much appreciate your help Keith. I've been on numerous forum but never got this good feedback.
I searched the PhilZ thread and got so many results. My model is i9100 of the Galaxy S2, I guess the methods you have been describing works for this model?
I need to backup program data and EFS before I dare start playing around.
How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
You can't. And you don't need to unless your phone is rooted, because if your phone is rooted nothing you can do to the phone is capable of borking the EFS/IMEI.
Edit - Also, I'm detecting a lack of knowledge of 'the basics' in the threads you've posted recently; I strongly suggest you read all the guides/tutorials stickied in the thread near the top of the General section before you do anything to your phone. A lack of knowledge exponentially increases the risk of you permanently breaking your phone depending on how little knowledge you have when you attempt to 'do stuff' to the phone.
For backing up the efs you'll need to flash a recovery first (like Philz as already suggested).
But anyway, problems with the efs won't be caused by just rooting so you can go ahead and root first and then use KTool.

Thank you. As I want to perform all the necessary steps directly on my phone, I am now thinking of doing the following.
Installing Framaroot (APK) and rooting my Samsung Galaxy S2 i9100 (http://forum.xda-developers.com/showthread.php?t=2130276)
Installing KTool and backing up EFS to external SD-card
Installing Titanium Backup (Root version) to backup AppData
Alt 1.) Downloading Mobile Odin to OS. Flashing ROM + GApps via this. But this keeps my stock recovery? (http://forum.xda-developers.com/showthread.php?t=1347899)
Alt 2.) Downloading PhilZ Touch Recovery 3.0 for Galaxy S2 i9100 which flashes + re-roots for me (?). Not sure if it's the right version as the post is old? (http://forum.xda-developers.com/showthread.php?t=1840223)
Alt 3.) Flashing CWM via Mobile Odin, and then in turn boot to recovery (now CWM) and flashing ROM + Gapps via CWM. This should update my recovery as well as my ROM?
After flashing ROM, entering recovery to Wipe Cache, Dalvik and Data
Flash ROM again as previous step supposedly deletes the ROM?
Boot ROM, Configure, Install Apps and restore App Data
Does the above look correct?
Is the version of PhilZ the correct one? It appears to be a 'temporary recovery' rather than a permanent, which might be what I am after if I want to flash the current version of CWM for Galaxy S2 from www.clockwerkmod.com/rommanager
Follow the instructions I gave in this post....
http://forum.xda-developers.com/showthread.php?p=48583106
and you will have a rooted phone running a custom ROM. No need to reflash the ROM after the wipes. Wiping cache, dalvik and data will NOT erase the ROM, all it'll do is erase any personal settings and downloaded apps.
Mobile Odin can't be used to flash custom ROMs, I think it can be used to flash CWM.... but only if you can find a compatible version in a .tar format.
PhilZ is still your best bet.....you will root your phone and install CWM in one hit.....all from your existing stock recovery. The CWM inPhilZ is NOT temporary, though it WILL be overwritten when you flash the ROM which will contain it's own permanent version of CWM. Just match your phones build version to the PhilZ kernel that you download.......
Why make extra work for yourself by increasing the number of steps you have to take (use framaroot then try to find a compatible CWM) when you can do it in one step?
And as mentioned before.....DON'T use ROM manager on an S2.....it breaks things....specifically recovery....one of your prime goals.....

I made big projects of things. As a complete novice within Android, I've read through numerous threads, made project notes, consolidated info and made Mindmaps to understand this.
From my understanding, a kernel (I've seen Siyah mentions on many places) is the interpreter between hardware and the instructions given by the software.
In which way is this comparable to a recovery partition/ROM, namely PhilZ?
I'm sure it's some detail I'm missing, and thanks for the tip.

Thank you once again Keith for your engagement and good tips.
I think the reasons why I am considering the different options, and also trying them out - is to get a broader understanding of Android and the alternative processes as I approach my goal of flashing a new ROM.
1.) So far I installed Framaroot and rooted the device successfully.
2.) I then downloaded Hellcat's kTool and made an EFS backup (and a kernel dump, whatever that is)
3.) Then I installed Titanium Backup and backed up all user + system apps (+data I think)
4.) I then downloaded CWM from www.clockworkmod.com/rommanager > recovery as a zip, booted the stock recovery and started CWM (locally, without replacing stock recovery for some reason), from which I did a full Nandroid backup (with stock recovery intact in this backup, I guess. Device was however rooted so it's not fully original).
I reckon I now just need to download my custom ROM and it's relevant Gapps.
I have read good things about Mobile Odin, and since a while back it supports *.zip files so I believe it is a good alternative for flashing custom ROM's now as well.
PhilZ was a bit intimidating, as there was a general thread and different model based threads in each subforum. They were also in different versions, dates and basebands. Also it appears to be available in a "permanent" download as well as a "temporary", which caused my confusion in the last thread.
I did not know that the recovery was replaced when installing a custom ROM, as I did not know that they contained their own partition of a recovery ROM.
Thanks for the information about not needing to re-flash ROM after the relevant wipes.
Thanks for the discouragement of ROM Manager, I promise to stay away from it.
From my understanding, PhilZ seems to be a modified version of CWM6, which includes ChainFire's Auto Root and some other add-ons as well. Is this a correct understanding?
You don't need to backup system apps/data from Titanium Backup because restoring them on a new rom will definitely cause issues.
Plus in case of a bad flash or something nandroid is always there for you so before doing anything new with the phone always do a nandroid backup.

[Q] how to revert back to stock jb I777UCMD8 from custom rom

I'm currently on pacman ROM v22. and i want to go back to stock jelly bean. I do have a nandroid backup but when I try to restore it fails. I guess its because of the latest cwm I.e. v 6.0.4. right? how should I restore the backup now? please help.. I'd be thankful

If you know what version of recovery you used to make the backup, install the kernel with that version of recovery. If the kernel does not match your current operating system, the phone will not boot into the system, but it should boot into recovery and allow you to restore the backup.
Or you could just flash the I777UCMD8 stock firmware with Odin, which you can download from the Download Repository.
as far as I remember I used v6.0 of cwm with the stock kernel.. yeah I was using stock kernel when I had v 6.0 of recovery.. should I downgrade to v6.0 cwm and try?
so I downgraded cwm to 6.0.1.0.. I guess that's the version I was using when I made backup.. tried to restore.. error: MD 5 mismatch
what does it mean?
new problem occurred.. :/
I downgraded recovery to 6.0.1.0 now I can't update it back to 6.0.4.5.. rebooted system.. and booted it back to recovery now that when I try to upgrade cwm I get error: couldnt mount SD card.. and when I checked my kernel has been replaced with cynogenmod #1 from aj kernel.. how should I get back the cwm 6.0.4.5 (I have .zip file is SD card but it won't mount in cwm) please help!
***ignore this I got it back working***
just tell me how can I restore the backup of my stock jelly bean
You can defeat the md5 check if you are absolutely certain that the nandroid backup is not corrupted. Sometimes just changing the file name of a nandroid backup will mess up the md5 sum, but the file is still good. But if you try to install a corrupt nandroid file by defeating the md5 check, you can do serious harm to the phone.
In this case I would not recommend even going there. It's no problem to flash the stock firmware using Odin. Yes, you will need to perform a wipe data/factory reset first, and yes you will lose your apps and personal settings, but there are backup programs for that. I would recommend this route.

okay but I didn't make any changes on the nandroid backup..
i have a question.. i'm using unlocked at&t here in india.. will upgrading firmware from odin lock my phone again?
and thanks for your help
There's also the option of using titanium backup restore the apps and settings of your nandroid backup.
settings > extract from nandroid backup > [select backup] > choose which apps/data that you want to restore.

well that's cool cryil.. but unfortunately I have no app & data backed up in my nandroid backup.. its just the stock ROM and settings.. while I was flashing the latest cwm I by mistake deleted my phone data.. so there is nothing just the stock ROM..
I just want to restore my nandroid backup to return to stock ROM.. I am away from PC for sometime so flashing with Odin is not possible at the moment.. I don't know what to do now..
(please also see the other thread by me)
thanks
is there any way to flash stock firmware through cwm.. I have cwm manager and it has a feature which says *flash the stock firmware* but I don't know how to use it... I don't care if I lose root access and cwm..

I'm not sure about that one.
But, you can still boot into your custom rooted firmware? If so, you can use Mobile Odin Pro or Mobile Odin Lite to flash the stock firmware from the phone.
yeah mobile Odin I have heard about it.. how to flash firmware with mobile Odin? we have to extract the .zip right? can you please tell me step wise procedure?
thanks once again
5 bucks says he's using Rom Manager app. Because clearly that'd be causing him issues.
yeah phalanx you're absolutely right. I flashed cwm recovery from ROM manager.. I didn't read stickies.. so I was not aware about the ROM manager causing problem thing.. anyways I got v6.0.1.0 of cwm after flashing from ROM manager.. I reeboted phone successfully.. checked kernel.. it was still the stock kernel.. If I'm not wrong flashing cwm replaces the kernel? anyways.. then I booted to recovery.. made nandroid backup.. upgraded cwm to 6.0.4.5.. flashed pacman ROM successfully.. and now that when I want to restore the nandroid backup it gives MD 5 mismatch error.. any suggestions ?

You can not install a .zip package with Mobile Odin. You can install the stock I777UCMD8 4.1.2 ICS firmware with Mobile Odin. Mobile Odin recognizes .tar and .tar.md5 files. The stock distribution, which you can download from the Download Repository, (see link in my signature) is a .tar.md5 file. Mobile Odin requires root access, so the following assumes you have a rooted firmware on the phone that will fully boot into the system.
Download Mobile Odin from this thread. Download the flash kernel from post #10 of the same thread. Install both apk's on your phone.
Download the UCMD8 .tar.md5 to the root of the internal sd card. I hope you have access to wifi because that is a pretty large file. Boot into recovery and perform a wipe data/factory reset. Boot back into the system. Mobile Odin will now recognize the .tar.md5 file so that you can flash it. Once you flash it, you will have lost root, and will have fully stock firmware and kernel.
wowie thanks for your help bro! downloading the .tar.md5 .. last question by my side.. I didn't use mobile Odin ever before.. so I dont understand what's that thing? I mean as I have .tar.md5 file I will then just have to click on flash firmware?? or there is something I am missing?

Once you have both the main application and the flash kernel installed on your phone, open Mobile Odin, scroll down and touch Open file..., select internal sdcard, and then select the .tar.md5. You should be able to figure out the rest from there.
I successfully flashed i777UCMD8 from mobile odin and didnt even lose root.. thanks creepyncrawly!

I do not have any direct experience with either of these issues. Maybe someone else will be able to answer.
some other guy told me to try flashing any other kernel? can I use any custom kernel with stock jelly bean? which one?
