so i flashed about 3 different zip files of CWM touch and all of them keep on saying "E:Error in /cache/recovery/last_log" and it wont let me wipe the cache or format it either, i dont know if i should attempt to go into odin and flash TWRP, but since i have CWM already i dont know if that would flash right over it or if it will have problems, if at all possible i would like to find a solution without having to go into odin so any help would be much appreciated, THANK YOU.
p.s. can do without snide comments
Read the stickies. Learn more about this phone. Or you're going to brick your device. Just stop flashing things and spend some time reading.

Hey, im new here, and completely new to the whole "custom rom flashing" thing.
I would like to get into rooting my phone and then installing a custom rom like resurrection for example, but I have a couple of questions.
1. Do I need an SD card in my phone, to be able to root my phone/install custom roms? or can I just use the phones internal 16gb memory?
2. Would someone be kind enough to point me to a guide to rooting/installing custom roms for complete newbies like myself? I have searched the forums, but theres so many threads about different stuff, like clockworkmod/odin/cyanogenmod etc, my head is completely boggled. I just don't know where to begin with any of it.
Cheers.
1) No.
2) Everything you need to know is in the Stickies.

1. No you cant root without an SD card? or No you don't need an SD card? elaborate please.
2. Nothing in that thread helps someone like me who is totally new. I don't know what any of it means. Surely there is a simple guide that explains exactly how to root your phone, without linking you to 7 other threads in the process? That's all I've found up until now.
This requires sdcard

Thanks, thats what I was looking for.
One more thing, just so I dont make a mistake, could you tell me which kernel to download? my kernel version is 3.0.15-I9100BVLPB-CL310231
cheers.
Read the bit in bold read which says 'Help ! Which file do I use ?'. This short section answers your question exactly.
ok well i tried CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5-PROPER.zip and my phone no longer boots....
tried CF-Root-SGS2_XX_OXX_LPB-v5.2-CWM5.zip and I get the same thing, so im stuck now. great.
I can get into CWM recovery, but I have no idea how to copy the rom I want to use onto the phone when its in recovery mode. This is something that is just not explained anywhere
help?
Right. In order of importance:-
1) No bumping threads within 37 minutes. Not cool. This is not your personal tech support forum.
2) You're having problems. Why ? Who knows. We're not there looking over your shoulder so we have no idea exactly what you did. I suspect you're having problems because you are in too much of a hurry/took shortcuts & didn't do what was suggested immediately after your OP.
3) However...Given the situation you find yourself in, I recommend you do one of two things:-
A) If you are absolutely sure you have CWM Recovery & not Android recovery (I say this because if your phone isn't booting normally, that normally means the flash didn't work & normally CWM wouldn't be successfully installed either), follow whatever instructions the rom you're wanting to flash has.
Every single rom on here has flashing instructions, normally on the first post on the first page of the thread on here devoted to the rom. If you can't be bothered reading those, I can't help you.
or
B) Go to Samfirmware.com. Search for the firmware that was on your phone before you tried to root it. Download this firmware. Flash the firmware you download following the instructions here. If you also end up with a .dll file, bin it. You don't need it. This will give you a clean install of stock. From there, I strongly suggest you read the CFRoot thread very carefully before you attempt to root your phone again. I also strongly recommend you read the Stickies linked to above, so you have some sort of understanding around what's what with this phone.
If you don't, being a betting man, I'll wager there's a fair chance you'll find yourself in the situation you currently find yourself in again (best case scenario), or worst case you'll end up with a 135gm paperweight as many people have on here over the past few days.
It's all up to you now. Your phone's destiny is in your hands.
Thanks for the reply, much appreciated.
Sorry for bumping, I panicked a little when my phone wouldnt boot. I just expected it to work because I have done things like this in the past and never had problems. Im a pretty tech savvy person really, im just new to android.
I wish it was as simple as reading one thread, but there are dozens of different threads on how to root this phone, and different methods, its extremely confusing.
Im downloading the stock kernel now (300+mb for some reason, and its going to take over an hour to download)
Once I get my phone back to normal, I'll read through some more threads and try and get a better understanding on how to root my phone.
I had it rooted properly as the recovery mode stated CWM in the corner, I think the issue I had was not being able to copy the rom I wanted to use, onto the phone, because I dont have an SD card.
Anyway, thanks for the help, and fingers crossed I can at least get my phone to boot again.
Man, I've never come across anything so complicated in all my life lol.
Edit: Sorted! Flashed back to original kernel and its working as it was before I started. Thanks very much for your help mate, and at least now I know how to restore my phone if I mess it up again in the future.
just thought I would update this thread and say I finally accomplished what I wanted.
Incase anyone is wondering, this is what I did:
Restored my phone back to factory settings/firmware/kernel
Booted the phone up, and copied my rom of choice to the internal memory via USB connection, and enabled debug mode.
restarted in download mode and flashed cf-root kernel (ended up with bootloop)
went ahead and installed the rom via clockwork recovery (creating a backup first)
The phone now boots into the rom im using (Resurrection Remix)
So if anyone is a little worried by getting the bootloop (but can still get into clockwork recovery) try flashing your required rom. Your phone may boot fine with new rom anyway. Mine did.
Not sure how to delete this, if a mod could please delete as I think this is probably better off in the i9305 Q&A..
I have a few questions all related to avoiding bricking by doing something stupid..
Where does CWM happen in the boot process, is it before the rom is booted?
I guess my real question is, if I decided I wanted to play around with porting ROMs to the i9305 (from i9300) and I stuffed up something majorly that resulted in me not being able to use the phone, will I be able to still get into CWM and restore a NANDROID backup or reinstall a stock i9305 rom?
Is there any possibility of a ROM wiping CWM and me losing access to recovery and my phone?
How hard is it to really brick a phone if you have CWM installed, what would a person need to do? (or more importantly what should someone NOT do if they dont want to end up with a paperweight)
Thanks in advance for your help.
report the post if you want it to be moved

Basic reason is EYES = refusing to read FAQS and GUIDES installing wrong firmware etc .In other words 99% users fault .

Hello guys! I don't ever get the need to post in a thread or comments, but this time I'm entangled in some pretty confusing stuff, I'd like help with please.
I bought a used GS3 GT-I9300 and tried to install a custom rom on it. One thing lead to another, a problem after every problem and now I'm at a dead end :\
Last time I was able to boot into a ROM, was via restoring through nandroid backup. But the IMEI had become "unknown". I searched it around to find that this was a problem with the EFS folder. Luckily I had a backup of the efs part before hand! But I can't even utilize the backup! -_-
The Problem is, whatever I flash via odin (no matter which stock rom), I end up stuck at the "Samsung Galaxy SIII" screen. I have a backup of the efs, but if I go through philz recovery, it's not able to find my backup. I've tried every guide at there, and been searching about a whole day and now I give and ask for help from you guys with experience. What am I supposed to do, to get to a point where I can use my phone? Really sad after attempting so many things. NEED ASAP HELP PLEASE! :'( Thanks in advance.

Start with the simple things first... Do you boot into recovery after flashing with odin and factory reset this is the most common thing that people don't do and this solves most bootloop issues.
Sorry if you have tried that but you really need to give a small brief list of eactly what you have tried to do because saying (quote) "attempting so many things" does not help us to narrow down what is wrong otherwise people will be suggesting things you have already tried.
Question makes no sense, if you can't find the backup in philz then you aren't using it correctly or the backup is in another format. You'll need to understand the basics before you go any further.
Search for people who've extracted the efs backup on their pc then copied all the files across, follow their example.

Thanks mate. Well I've done that. Separately tried clearing cache alone and rebooting (didn't work). Then also tried factory reset (via TWRP) that didn't work either. Then I tried factory reset + clearing cache which didn't work too. No matter what stock rom I flash via odin, or a custom ROM via recovery, My phone does not proceed ahead from the "Galaxy S III 3G" Logo.

Can you maybe give me the link for that please? I didn't even intend to backup efs, this is something which luckily happened accidentally haha.
In hope for seeing if I made a efs backup, I searched the internal storage + SD card of my phone and narrowed it down to 3 rar files:
1. efs_01Jan2012-0001.tar.gz (52KB)
2. efsbackup.tar (5.05MB)
3. efsbackup.tar.gz (62KB)
First off, if I have done anything wrong by starting this thread, please correct me instead of bashing. I ltried simply rooting and installing twrp recovery on my lg vs450pp. Somehow I managed to get twrp recovery, but in the process I completely erased all internal storage, no OS. Then whole trying to save it, I flashed the stock recovery, and no longer have twrp. Can anyone tell me dedinitively if it is fixable or if I'm just up creek without a paddle? If it is fixable, knowing how to would be great, but at this point I really just need to know if it is first. Giant thank you to anyone who takes the time to try to help me.
Hi sirs,
The title says it all, I want to change back to stock rom or change to other custom roms but I am not sure what to do. I have cm12.1 nightly build 5.1.1 (i guess that's the name) currently installed in my phone. I followed a tutorial on how to do THINGS in my phone but I am unsure whether it will work or not. I am SO VERY VERY VERY new to these things and I don't know how to proceed. And also, i get confused of the terms like KERNEL or ROM and i kind of mixed them up. So I am here to ask for your help and clarification on my problem.
According to a tutorial that I've read, a custom recovery is needed. So, following a tutorial, I replaced the Cyanogenmod recovery with TWRP recovery. My questions are:
1. Is it safe to flash a ROM (like Omega Series Rom, which I kind of bumped in while doing research) over the current CM12.1 system?
2.Is there any patterns or magical incantations in order to flash a new rom into my device successfully? If so, can someone show me a step-by-step instructions?
3.Will it brick my phone if I missed a step?
I know this is too much to ask for, but please help me Sirs/Maams. I'm desperate. THANKS SO SO SO MUCH in advance.
P.S. Sorry if my english is so horrible. English is not my first language.
Sincerly,
Me
To install a new ROM, boot into recovery, and wipe /data and /cache and if you want also /system. After that install the ROM and Gapps zip files. Always double-check you're using & choosing the correct files. I recommend to always use the smallest possible Gapps package to make sure it fits into the /system partition.
Make sure you're using the right recovery. For example Cm12.1 needed a KitKat-compatible recovery for a successful install.
Notice that all apps and app data will be deleted at a new flash. In some cases, the recovery is included in the ROM, then it will overwrite the one you had before.
I personally think flashing a new ROM isn't that dangerous. There are more critical things, for example repartition. But there are some rare cases at almost every ROM where someone's phone dies, for whatever reason. So there's always a little risk. But even if you should succeed soft-bricking your phone, there already are some guides how to solve it.
And one more tip: in general, always read as much as possible about a ROM before flashing it. Avoid less documented ROM threads. You decide what you risk and do everything on your own responsibility.
I know this things are logical, but it seems as if there are still people flashing everything, reading nothing, spamming everything with their problems they get then
Hope I helped you a little bit.

Thanks for the reply kind sir.
So it's safe to flash a new ROM over the current CM12.1 system? And if so, will my current recovery (which is TWRP recovery) suffice for flashing a new ROM? or do I have to replace my recovery? If ROMs have compatibility issues with recovery systems, can you please give or show me a list of ROMs that can be flashed using TWRP recovery (I'm so sorry, I have don't completely understand these kinds of things).
Thanks for your help sir. I really appreciate it. And sorry for the questions.

It's safe to flash whichever rom you want over cm12.1. The only thing to keep in mind is whether it is a .zip file or .tar file(as for stock rom), which will tell you whether to use recovery(your TWRP is fine for this), or odin(for stock rom in .tar format)
But as BenjiTec said, READ, READ, READ before you go ahead and flash a rom. Always read the OP(first post) and maybe first 2 or 3 pages of the rom thread, plus the all the pages from when the rom version you want to flash was released(maybe 10-20 pages). You probably don't need to read ALL pages if it is an old version. Understand what you are doing, rather than follow steps blindly, and you will always know what to do in case of something going wrong
Thanks a lot sirs, both of you, BenjyTec and noppy22, for the clarification.
One last question (or sets of questions. sorry )
So I have decided that I will flash a stock ROM to my S2 from SamMobiles using Odin. Do I have to wipe the the /data, /system, etc. before flashing the stock ROM via Odin? Or i can just directly flash the ROM over the CM12.1 system and TWRP recovery? And I have searched a lot of the possible outcomes and failures (like Odin ROM installment failure). What are the chances that the installation will fail? And what do I do if it DID fail (let's hope not)?
I know that these kinds of questions have been already answered in many threads but I just want to have my answers DIRECTLY from experts. Not from old threads and guide thingies.
Again, THANK YOU SO MUCH for the clarifications and answers. GOD BLESS

It doesn't matter so much whether you wipe before or after. The easiest way is:
1. Run odin on your pc
2. Connect your phone, after booting in download mode(turn off, then hold vol down, home, power buttons until samsung screen) Use a trusted data cable, not all cables work
3. Flash stock rom through odin until PASSED(untick reboot device/auto reboot before flash)
4. Disconnect phone, take battery out, then put it back in. Reboot to recovery(vol up, home, power buttons)
5. In stock(3e) recovery, do a factory reset
6. Reboot and leave it for 5-10 minutes until you get a brand new stock rom
Stock ROM installing succeeded! THANKS SO MUCH SIRS! THANKS for all the clarifications and answers to my questions! KUDOS to both of you!!!
