[Q] I think I've stuffed up "Badly"!! - Galaxy S II Q&A, Help & Troubleshooting

Hi Guys,
I'm new to this Forum and very new to Android. I have the Galaxy S2 and while attempting to install Clock Work Mod, following the instructions from GalaxyS2Root, all of a sudden the phone locked up at the Samsung Galaxy S2 sceen with the yellow exclamation mark and that's as far as I got.
With great difficulty, I can get into the recovery screen, but I haven't got a clue, what I can do from here.
Is the phone recoverable, or have I just destroyed a brand new phone? I don't have a rom zip on my sd card, so I couldn't install a new rom from the card.
I have tried everything to get it going again, but I think the more things I try, the worse it gets. I think I have now wiped the existing rom off completely and wiped the caches, all because I was panicing.
I even thought of removing my sd card, putting it into my wifes Galaxy Ace and downloading a replacement rom to it and then try to install the new rom back to my phone.
But guys, I'm really panicing here and don't know what to do!!
Can anybody please help me out, or do I now throw a brand new phone into the garbage?
Thank You.............dixie (Help Please)

Just flash a new firmware via odin.It will be new again

Hello,
You could try downloading the rom required and install using odin.
You will need to make sure you get the right version for your phone and use odin to flash.
I've not done exactly what you have before I got into a simple boot loop and had to re flash. Live and learn I guess!

Thanks for your reply,
But how do I connect my phone to Odin and what menu should the phone be in, in the recovery mode?
Doesn't the phone have to be in the download mode?
I can only seem to get into the basic recovery mode, ie volume up + power + home keys.
Regards..............dixie.

Have you tried to get into download mode (volume down + home + power)?
You should be able to do that if you can get into recovery. Once in download mode, connect to your PC, start Odin and choose PDA, then select the tar that you have downloaded (it will be in zip form until you unpack it).
Read some threads about Odin/Download mode before you start and make sure you are happy to proceed.

O'k I did as you told me, but the first strange thing is, when I extract the zip file I get the following: boot.bin, cache, factory fs, hidden, modem.bin, param.lfs, Sbl.bin and zImage.............there is no exe type file!!!
However if I open odin, click on PDA and enter the whole zip file location and press start, everything goes ahead as planned.
I get a "Pass" and the phone restarts, I get the small tune and the blue moving lights on the screen, but then it just jams up, on the S Samsung Galaxy S2 screen. That's as far as the boot sequence goes.......frozen on the Galaxy S2 Screen!!
Any suggestions?
Regards......................dixie.

Pull out the battery, wait a few seconds replace and try to boot again. If that doesn't work, check you have the correct firmware to flash and try again with Odin.
Or have a look at this thread:
http://forum.xda-developers.com/showthread.php?t=1457458

Right, for starters you need to give relevant information if you expect accurate help otherwise you're going to end up screwing your device up.
Which model of S2 do you have?
Which rom do you have? (give link)
Which guide did you follow? (give link)
If you can get into cwm its just a case of "wipe data/factory reset" and then flash custom rom of your choice from sdcard. Just go into cwm>mounts&storage>mount USB (this will mount cards onto PC if connected) so once connected copy your rom across.
I recommend the new wannam lite rom if you want new samsung JB based rom.
If you want to flash via ODIN then you should only be flashing a .tar or .md5 file in PDA section. If your extracting a zip and you get all the files you mentioned in your above reply then you have wrong file.

O'k thank you for your reply and thank you to the others that replied.
I was using an incorrect rom to flash and an incomplete rom at that!
I downloaded a different rom, extracted the files and flashed with odin. Now I am up and running and have the phone back to full woking order.
That was pretty scarery stuff and I thought I had bricked the phone for ever, I guess a little knowledge is helpful but dangerous, if one isn't sure of what they are doing.
Thank you once again for your help, it was much appreciated. I'll contact you again no doubt, next time I create a stuff up.

Hi Guys, one last request. I would like to root the phone and after a considerable amount of reading/research, the root file that I require, seems impossible to find. When I do find it and download, the .rar file is empty except for a zImage file!!!
My phone is the Galaxy S2 i9100 running ICS 4.0.3 Baseband Version i9100XXLPQ Kernel Version 3.0.15-i9100XXLPQ-CL223505 Build Number IML74K.XXLPQ.
I bought this phone, while I was visiting China and it has been great, up until I managed to brick it by accident.
Anyway, I apparently need the CF Root for XXLPQ v5.4, which I have downloaded six times, from various sites and every time I extract, it's empty, except for an image file!!!
I live in Australia and use the Telstra Network.....should I change to a more suitable Firmware, or maybe a stable custom rom, or can someone give me a link, for the appropriate working CF Root file?
Much Appreciate and Thank You........dixie.

Ignore the above post guys, a little more reading and I found my mistake.
However, I am still interested in the suggestion of a Custom Rom, which would work successfully, on Australian Networks.
Cheers to All......dixie.

I'm still new myself here but i'm sure ur phone is already rooted from what u said above. When u boot into recovery does stock recovery load or CWM ? if anything other than stock Samsung recovery then your already rooted.
Also u dont need to unzip the rar file its ready as is.
If ur phone is actually not rooted by far the easiest method is here http://forum.xda-developers.com/showthread.php?t=1501719
u dont need an insecure kernel and theres no risk involved even if u mess up. I was a lil hesitant to root my phone but used that method and all went fine, now i've learned so much in the past 2 weeks i'm flashing other kernels and tried lots of roms.
Peace

Yes thanks for the reply. I discovered that I didn't have to extract the root file, as it was already a .tar (stupid me).
So now I have a rooted phone and the Official ICS version XXLPQ, which is working in Australia, but I have noticed, that most of the time the Network is showing "edge".
All I really have to find now, is a good, stable, custom rom, that will also work in Australia.

A couple of observations....
You don't need "a good stable custom rom that will also work in Australia". Region has nothing to do with how a rom performs/your experience with that rom. If you're having issues with connectivity/you're not happy with data speeds, flashing/trying other modems may help. I suggest you read through this thread, at various times people have discussed which modems have worked well with different carriers (particular modems seem to work well for most people using a particular carrier). You can then search for CWM flashable versions of these modems & test them out until you find one that gives you connectivity you're happy with.
The other observation is you're a bit lacking in the 'basics'. I highly recommend you take the time to read through the guides. Knowing the basics makes it less likely you'll bork your phone at some stage, and that you'll be able to solve any problems that come up in a methodical/logical way (as opposed to guessing).

........a bit!!!!!!

Since you are on 4.0 3 ,why don't you flash the official jelly bean XXLS8 update via odin? Than root it with cf root

[Q] [nOOb Q] Semi bricked phone stock -> CM7.1-> ICS-> CM7.1 -> Bricked

Hi there, please go easy on me. I did search XDA, googled other places and tried other things but getting the same. I am coming from iOS, got SGS2 and played a bit with it. Decided to flash new ROM as samsung stock was slow.
1. Rooted my phone with SuperOneClick.
2. Installed ClockWorkMod.
3. Downloaded CM7, put it onto my SGS2 and installed with ClockWorkMod (volume up+power+home)
4. Went further and got mysellf Simplistic ROM ICS XXLPB installed it with ClockWorkMod
5. Wanted to go back to CM7 so tired installing it with ClockWirkMod but something went wring and I ended up with sem-bricked SGS2
Whenever I fire up the phoone, the battery logo appears but is doesnt show itis charging. When I connect to KIES is isnt connecting the only (good) thing is I can put it in a download mode and Odin sees it so I caan try flashing it but whotever rom I am flashing in, I am getting the same "Invalid MD5 value."
I wanna go back to stock rom ERA PL (I9100XXKE4 ERA 05.2011 2.3.3) when I unrar it i got the following files, seems like PIT file is missing. Have a look at the attached. How do I restore my phone with ondin?

Im not an expert so you might want to wait for a more experienced persons comment....
but go to sammobile.com and download the firmware you want to flash....if PIT file is required you can search for it i believe, i remmeber ive seen a place earlier where you can download it.
Hope it helps

Pit comes with each firmware but onSGS2 so far i believe its the same one . Details are on the site you got firmware from follow their instructions .
PIT file is not required and its dangerous for noobs to use .
Invalid MD5 value.
Two reasons why One bad download file corrupted or Two the more usual user is not following the instructions and making their own up .

Thank you for your invaluable help.
can flash cm7 GT-i9100G ????
Go to intratech's thread about firmwares and download from there. And don't use PIT. You don't need it.

[Q] Black Screen Help!

Hi guys, just new to these forums. I was forced to sign up due to my problems. just about 2 days ago i flashed these to my Galaxy Note Korean unit (SHV-E160S):
Tegrak-Kernel-Build-32-for-SHV-E160S-FA09.zip
Tegrak-Kernel-Build-32-for-SHV-E160S-FA09recovery.tar
i used Odin to flash the recovery file then booted into recovery mode to flash the kernel.. im sure i did right because i was able to use superuser and change my boot animation. unfortunately i found another update to the .tar and .zip file. i'm pretty sure its for my phone too so i went ahead and did the same thing. i kinda made a mistake in the process, i think i wiped the cache and all. dunno if i wiped partition but in the end i am only able to go to recovery & download mode. the Note will power up but won't get past the "Galaxy Note" screen. after that i will just be black. it's weird because it can still connect to Odin on my laptop although the screen is still black. is it a soft-brick? right now i'm trying to download an ICS stock rom and will try flashing it with Odin. i someone can help me please do. sorry by the way if this is a Korean Galaxy Note. this is the best category i could post since the AT&T and the SHV-E160S are the same in specs and all. hope someone could help me and spare me the pain from sending my unit for repair!
Sounds like a soft brick.. it seems you flashed perhaps the wrong file the last time otherwise it would be working like the last flash? ..I don't use odin often but I would restore my backup or just start over and use the last files to flash until you find something different
yeah i tried the others. i am able to flash the 1st recovery.tar but i cant seem to copy the .zip kernel because i dont have access to usb
about to flash stock ICS using Odin, hope this works! i just have one file which is a .tar file, hope this is the right file and don't brick!
OMG, i just pissed my pants *kidding*, the flashing of the stock ROM worked! and not onl that, i'm on ICS! all thanks to xda=developers forum for giving me the idea to flash a stock ROM! thanks guys! i'll never root my phone again i'd rather stay safe. thanks for the reply friend! ICS rocks!
Could you give me stock ics rom for e160s? thanks

[Q] Samsung Galaxy S2 won't boot. Recovery mode not accessible.

Hi all!
I have a Samsung Galaxy S2 which I since a week cannot start. It get stuck on the black/white samsung logo. I cannot enter recovery mode, nothing happens when releasing the power button after pressing volumeup+home+power buttons. I can however reach download mode. I'm not sure what caused this problem, one day I just couldn't start it. I read on forums that many similar problems seem to have occurred when upgrading android but I'm not sure this is the case here (unless the phone made an automatic update while I was asleep). I'm not sure what version of android I'm running, but I'm pretty sure it is at least the ICS.
I would like to hard reset my phone if possible. It seems to be easiest through the recovery mode which I cannot get into.. I read things about Odin, connecting the phone to the computer and downloading android to the phone but haven't quite grasped it. Could anyone explain this option for me or point me in the right direction? Are there other options?
I would appreciate any help, especially since my 1-year warranty expired a month ago!
Best regards,
Marcus

Sounds like the symptoms of a NAND RW corruption. Try this http://forum.xda-developers.com/showthread.php?t=1457458
Hi Marcus,
I had the same problem few days back.
If it's not broken by you trying something fancy, the best solution is to take it to service centre. If you have rooted your device, had installed some custom firmware or are not willing to visit the service centre for some other reason, please read ahead.
All I did was,
Installed USB connectivity drivers through Kies.
Installed ODIN 1.83
Ensured that Kies or any of its processes are not running in background.
Downloaded the official SGS2 firmware
Flashed the firmware through ODIN.
It took around 10 minutes for the full process and I was having my mobile up and running. Using ODIN sounds scary initially if you haven't used it. I have slowly started gaining confidence in it after using it a few times.
Please note that though the process is well proven to be safe, there is still an amount of risk involved.
Sent from my GT-I9100
Download a siyah kernel(like v4.0.1) .tar file and flash through odin.
See if that makes it boot/lets you into recovery.

A couple of things..ensure KIES is not running on your computer in the background. If possible delete it completely. Also ensure your phone is connected to a USB port directly on the computer and not via a hub or to a USB port on a keyboard or something. Odin is a finicky s/w..so..
Also, try different versions. If v1.85 doesn't work try v3.4

Lol at underlining. if you flash a custom kernel like siyah, you'll be rooted and get CWM. Using that you can install a custom ROM.
Sent from my GT-I9100 using xda app-developers app
And youll be safe from the 4.0.4 brickbug if you flash siyah.
You flash a kernel for various reasons like it has emmc cap disabled,you can tweak it etc.
You can flash siyah kernel and stop there.Or you can move onto a custom rom.
Whatever,when its done-backup your efs and make a nand backup.
And yesterday I was downgrading my wifes phone onto 4.0.3.I was using odin and kept getting "failed".After 3 attempts I realised I hadnt put the phone into download mode..........how stupids that......lol
hi there, just wondering, after Flashing the stock firmware through ODIN, do you lose everything in your phone? i need to get all the notes that I have in my phone (notes from the samsung stock apps). I dont have any external sd card in the phone. thanks in advance for the reply.

Hi there sir,
Has the problem solved ? Care to share the solution ?
Thanks.
i had the same exact problem, i tried flashing with odin n stock firmware but stuck in NAND write start, i didnt try flashing with PIT & repartition though, i couldnt be bothered anymore, so i took it to samsung service plaza, they told me the problem is in the main PCB (hardware issue), so all they did was replace that n it got fixed! i didnt pay because it's still under contract/ carrier warranty

I had a similar problem, stuck at boot with Biftor v12, which happened after I tried to update SuperSU binary through CWM/TWRP. I don't know why it stuck at boot and why it wouldn't reboot to Recovery. Download mode was still working, so I had no choice but to flash new kernel through ODIN and see if it works.
So if your symptoms sound similar to mine, here's what I did to be able to boot again:
I REPEAT, SIMILAR TO MINE. MY SOLUTION MIGHT NOT NECESSARILY APPLY TO YOURS.
1. Download a suitable kernel in tar.md5 format. I used PhilZ-cwm6 v4.93.6 for XWLSN firmware (see OP http://forum.xda-developers.com/showthread.php?t=1877270)
2. Download ODIN, if you don't have it, found here http://forum.xda-developers.com/showthread.php?t=2189539
3. Once installed, boot your phone in Download mode by pressing Vol Down+Home+Power together until you see a warning dialog. Press Vol UP to get into download mode.
4. Make sure ODIN is running, and NO KIES processes are running.
5. Connect your phone with USB cable to your PC.
6. In ODIN, you should see a COM port with yellow background.
7. Click the PDA button ONLY.
8. Select the kernel file you downloaded.
9. Press Start and nothing else.
10. If everything went as expected, your phone should reboot after a while with a working Recovery.
Only do the steps if you are absolutely sure. This worked for me, and I hope it gives some tips for your problem as well.

6. In ODIN, you should see a COM port with yellow background.
7. Click the PDA button ONLY.
8. Select the kernel file you downloaded.
9. Press Start and nothing else.
10. If everything went as expected, your phone should reboot after a while with a working Recovery.
Only do the steps if you are absolutely sure. This worked for me, and I hope it gives some tips for your problem as well.

Hi Flash-IS-Bright
I have the exact same problem with SuperSU on my rooted Galaxy S2. I updated the SuperSU app, and when I opened it, it recommended me to update the binary, I selected the CWM/TWRP option and then my phone tried to reboot but is now stuck. It can only access download mode.
In doing the process above, you only flashed the kernel? Did this totally work? And all your apps/messages were left intact on your phone?
Any help is appreciated.

when ur updating the binary u should always choose the 'Normal' thing instead of the 'CWM/TWRP' one ma8
if u flash a kernel it will not delete anything on ur phone, all u have to do is to select the right kernel like 'Philz' for example (if ur on a stock JB firmware) and flash the same through 'ODIN' and reboot ur phone

Thanks for your help. I've originally had Jeboo 1.2 kernel on my phone and tried to reflash that again through Odin. It passed, however I'm still encountering the same problem of the bootloop.
Would flashing a different kernel help? I'm on stock JB firmware but with a Jeboo kernel. I am happy to try another kernel (if that would not brick my phone)
Do you have any other suggestions to help me solve this?
Again thanks for your help

You could try flashing hawkerpaul's kernel wiper first and then install another stock kernel like PhilZ or Apollo, and see if that helps.
Neat Rom lite,suddenly struck in boot loop after 1 month of operation.
Dear All,
I have installed the "I9100XWLSZ_NeatROM_Lite_v5.0.1" custom rom and after 1 month of successful usage, today suddenly the phone was dead.(probably due to autoupdates over wifi) . I tried to reboot, but didnt. Tried to restart but got stuck in the logo screen with yellow triangle.
Tried to enter recovery mode, but no use. Only download mode is possible.
Tried to flash the stock rom using odin, but no use, Nand write failed.
Can somebody help me how to come out of this situation. Shall I install a different kernal and see?
Regards,
Maka11

Stuck in CWM Recovery

Hey guys.
I've searched the forums for this issue, unfortunately it seems like mine is a little unique and I can't find a solution to my problem anywhere.
I'm stuck in CWM Recovery mode, and although I can navigate the menu... when pressing the Home key to select the various options, nothing happens besides the options blinking for a sec. I can access Odin Mode with Power/Volume +/- but that's it. Also it's worth noting that I'm unable to access my phone's files from my computer when in download mode (my guess is because the phone isn't set to USB storage mode which I have to do from the booted home screen, which... I can't access).
This happened after the first time entering Recovery mode on CWM, and although I have ROM Manager installed on my phone, after researching a little I found that was NOT what I wanted to use. And I did NOT use that program.. my CWM was flashed in from a .tar on Odin (the windows program). I also have a Jellybam folder placed in the phone, which was my next step.
How can I get out of CWM Recovery so that I can continue flashing the Jellybam ROM?
I apologize if I've missed anything. Please let me know if you need any other information. I'll be sure to hit the thank you button on every reply.
THANK YOU!
:crying:
um....
you are supposed to flash the ROM from CWM, so why would you want to get out of CWM to get back into CWM?
you havent mentioned what version of Android you were already running or what kernel you flashed, but have you tried using the POWER button to select things in CWM? Are you sure you used the right kernel? Are you sure you have an i777?
Hey Pirateghost, thanks for the reply! And yes, I was going into CWM Recovery to flash the ROM. The reason I wanted out of CWM was because it had no functionality... yes, I did try using the power button to select things. Seems the home button was it? In any case nothing worked. My version of Android was Gingerbread UCKH7, and I'm %100 sure it's an i777. By using the "right kernel" you mean the right version of Jellybam?
UPDATE: I got out of the bootloop by using a stock root UCKH7 kernel, bringing it in from Odin. Now I'm just trying to understand what went wrong and how I can continue to flash my Jellybam ROM in without any issues. I also found that my CWM app disappeared after I uninstalled ROM Manager after getting access back to my phone.
More info...
the kernel I installed for CWM was KH4 at this thread: http://forum.xda-developers.com/showthread.php?t=1103399
After putting the KH7 stock root kernel in via Odin and getting out of the bootloop, I deleted ROM Manager off my phone and reflashed the KH4 kernel so I could get CWM. That worked fine, but now Superuser is crashing.

The kernel you just linked above is for the GT-I9100, not the SGH-I777. You seem to be moving forward without providing yourself with enough knowledge. If you are sure the phone is an I777 then stay away from the I9100 forums. Get what you need from here. There is lots of information in the guides linked in my signature. There is enough information there to guide you through everything you want to do.

You are flashing an older kernel on a newer ROM??? why? if you want to have CMW recovery you should flash your stock rom and then get the CWM .tar file and flash it in Odin. If you happen to get a .zip CWM file you can rename it to update.zip and flash it using your stock ROM's recovery options.
Search something along these lines: CWM5.8.1.8-i777.zip or recovery-clockwork-5.0.2.3-galaxys2att.tar as examples

It's great having new folks around helping out.
This is bad information, however. 3e recovery will enforce signature verification on any update.zip, and it will fail.

always a pleasure to lend a hand. you're right it used to work on 2e I think, I was trying to signify the difference between the zip and tar, but thank you so much for the correction.
So should I be using a different kernel? I'm sorry I'm not quite sure what you're saying Commodore64, my head has been spinning from all this.

you should be using a kernel intended for your phone....your phone (if branded AT&T) is either an i727 skyrocket or i777. this is the i777 forum section. you appear to have flashed a kernel for an i9100...
just follow creepy's guides and do it the right way. there is nothing you can flash in STOCK recovery that will give you CWM or a new kernel (which on this phone CWM is packed with the kernel)

There is not just one answer, you can go back to one of the stock ROMs, like the ones provided by creepyncrawly threads.
There are a lot of threads on this and I don't have my I777 anymore but I used to do this:
1- Once you flashed a stock rom, go into recovery and cleanup. data/cache reset.
2- Have the files you want to flash on your phone. (if you format the SD card you will erase your files including the ones you want to flash!)
3- Use your .tar Odin CWM that worked for you before now to flash CWM.
4- Once in the CWM flash a newer CWM version (CWM6.0.1.0-i777.zip) since your ROM is based on CM/AOKP
5- After flash Go to Advanced and reboot recovery (this will reboot your phone now with the newer version of CWM)
6- Once in the newer CWM clean up again.
7- Don't reboot, have the correct version (latest or whatever) of your Custom ROM and install it now.
This is the general idea, if you don't know what you're doing read the threads in the development section, everything you need is there.
Educate yourself before you make your phone a crippled rabbit and scream for help.

this makes no sense, dude.
1. if he is on a stock rom, there is nothing CM/AOKP on his phone
2. on this device the recovery is packed with the kernel, flashing some other CWM doesnt really matter at all. none of this is necessary.
you can flash any kernel you want (made for this device) if you dont plan on booting the OS and only plan on flashing a rom...
you have now complicated an already easy method.
Hey everyone - just wanted to let you guys know that I am now running JellyBAM and so far everything seems fine.
Thank you all for your help, seriously. If anyone has any questions about what I did etc., just ask and I'll get back to ya.
Thanks! :good:
Glad to hear you got JellyBAM up and running xargis, and just to reiterate what pirateghost was saying, you won't get CWM by flashing a CWM.tar file lol, I don't even think one can be found for this model (SGH-i777) which is the device that I currently have, the ONLY way to get CWM onto this device is to flash the proper kernel for this device, but keep in mind that there is another factor to think about as well, depending on what type of custom rom you want to run there are different kernels out there that work best and offer different/better features for deployment into the custom rom for which you will be running, in other words some roms are kernel specific, you can only use certain kernels with CM10/AOKP/ParanoidAndroid based roms, and such is the same with only using certain kernels with Sammy based stock roms, so the choice is yours, hope this info was informative to you and that you definately find a good productive rom that you will be happy to play with and run, have fun with your i777 s2, that's one of the things this forum is all about!!

Do you mean you can't even get into recovery? If it can, I would think a data wipe might get the ROM to be able to boot.

You might want to double check if you are using the right version of recovery that kernel is fully supported with your ROM. For example, if you are trying to install a KK ROM using an old version of CWM you will end up in error 7 or end up in a boot loop screen. My words are pretty mess up but I hope you get what I mean. So make sure you have the right version that match each other (recovery, kernel, ROM).
Hope that helps.
im new to all of this. when i hold the home button the power button and the vol down button i get a screen telling me installing a custom os could be bad press up to continue i do this and install even the official software but when it reboots it keeps looping on the samsung logo

I suggest you flash a working recovery via odin first. Look for TWRP, it's the best newbie-friendly recovery or try CWM if you are looking for more advanced options. After that, flash a stock or custom ROM to get your phone back working. Make sure they are compatible with each other. Why didn't it work when you try flashing the stock firmware via odin? Make sure the zip file is downloaded properly.
Hope that helps.

It seems like you have broken files. Make sure those firmwares are for the right model of your phone. Are you using I9100 or I9100G? Is your phone still under warranty? What do you mean by not network based? I think it's time you head on to NeatROM JB 4.1.2 Aroma and flash that to your phone. It's way better than the stock one from Samsung. If you don't know how, read the instructions from the OP.
Hope that helps.

This error is most probably because you don't have the right Rom for the right model or not compatible hence the verification error. Are you doing this in recovery mode? Make sure you follow the installation instructions properly and download the right one for your phone model. Just try cyanogenmod for starter. Installation is easy to understand.

ok so i went to cyanogenmod downloaded the newest file for the s2 when i did unzip i get 2 folder meta-inf and system plus a boot.img file. i burned the boot file to a disc but when i check it the disk is empty even though i can see its burned. also when i go to sammobile to get firmare it says no files available...therte must be some way of getting this to work H E L PPPPPPPPPPP
Dude, you're not supposed to be burning anything to discs. The zip file is what the recovery uses to install from. It should include the custom kernal too.
Copy the zipped ROM file to your SD card, put it in your phone and boot into recovery. Assuming you've already flashed the latest custom recovery CWM or TWRP (I prefer TWRP)
From here, to be safe, do a full wipe (That's everything except sd-card: system, data, cache, dalvik-cache)
Now you install/flash the zip file via recovery. Hopefully that completes without error. After that clear cache and dalvik-cache again just to be sure (I do this out of habit)
Reboot.
Hope this helps. I saw you mention something about "efs" and that gives me a bad feeling, read something about needing to back that up before bad things happen. But anyway, good luck :good:
