S2 NOOB flashing - Galaxy S II Q&A, Help & Troubleshooting

ok i recently purchased a samsung s2 i9100p with a software issue in the hope of fixing it. i didnt understand at time of purchase that custom roms/kernals etc might have been loaded onto the phone and now im completely confused.
what i know about the device is when power button is pressed i get the black samsung s2 i9100 loading screen and no more
ive then read about how to enter recovery mode and the phone doesnt boot into it but will boot into download mode which reads the following
odin mode
Product Name: GT-i9100
Custom Binary: YES (8 counts)
Current Binary: Samsung Official
so i have no idea what versions of the roms,kernels etc i require as i dont know the current versions installed if any. And i have read about devices being rooted and unrooted which has left me confused in that aspect.
i did locate an official ROM file for i9100p with orange lock which is what i believe i need as the phone has orange logo on back cover. but when i get into odin ive tried both old and new versions the phone get to the NAND Write Start Stage and then Fails.
Anyone out there any advice as to what im doing wrong? it would be greatly appreciated

Search for Hopper8's 'Odin troubleshooting' thread (do an advanced search on his username), try the stuff in that thread. You should successfully be able to flash it.

Thanks for quick reply il have a look at that now and see if i can get any further with it

It's a great thread/pretty much 'the reference' for this sort of thing on here, I'd be surprised if you can't recover it/get a successful Odin flash done with the info in it.

thanks alot mate at least i have a reference of what i should be doing now
downloading the files for this step
"Another option for i9100
If you have an i9100, probably the best option to flash is to flash 4.1.2 JellyBean leak. Download it here. This is a 3-part firmware. It will wipe your device as it flashes, and in many cases this extra wipe while flashing contributes to a successful flash. To set this file up in Odin (as it is 3 parts): PDA = CODE_I9100XXLSJ.tar, PHONE = MODEM_I9100XXLS6.tar, and CSC = CSC_HOME_OXX_I9100OXXLS1.tar. As usual, do not tick 'repartition'. "
in the hope the multiple files will be more successful than just the PDA> ROM flash i was trying. will post and let you know how it goes

Yep, hopefully the 3 part wiping the device will remove whatever remnants of what was previously on the phone that are causing the phone not to boot normally.

ok an update on my problem left it in repair shop and they managed to get it to boot to recovery but when i try and reset/wipe i am presented with a fallen over android with red triangle, its still stuck on boot loop but at least now i can access both recovery and download mode.
i also purchased a usb jig to try reset the counter but it doesnt reset must be whatever firmware on the phone from what ive read. after doing a check imei.info it shows that the phone is still under warranty until feb 2014 but i know because its been tampered with they probably wouldn't look at it
any guidance/suggestions would be greatly appreciated

[Q] Device won't power on

I was trying to flash this: http://www.darkyrom.com/community/index.php?threads/odin-darkyrom-10-2-resurrection-gt-i9000.4272/
I was following the instructions word for word & after step 9 it went down hill.
In odia I did pull the battery out while it read "partitioning" as I was waiting 10mins & it appeared to not move, it didn't even seem to start.
After I pulled the battery & tired to power it back on it wouldn't work...
I tried to get into download mode, recovery & even tried a USB JIG as it was likely to force it into download mode & yet nothing, not even a vibrate.
The phone in my eyes is the best out there so I would really appreciate all the help anyone can give me.
Use odin to install the rom again.

Firstly try getting into Download mode, I hope it works, secondly, read properly before flashing anything to your device, the link you posted is for the I9000, the Samsung Galaxy S 2 is the I9100

Never click repartition or mess with pit files!
I Bricked my phone because I clicked repartition. I had to play dumb took it back for service and they repaired it.
I have had my phone back and flashed it many many times but never clicked repartition again and had no major problems since.
The boot section sits on the partition so when you click repartition it bricks the phone. Clicking EFS will clear your IMEI number so leave odin as default.
I guess the repartition must have its uses for some phones but all I have read on the s2 everyone who has clicked repartition has bricked there phone.
Like many people I was given the wrong instructions on another site.
I will have a look around and report back if I find any fixes for this.

I did research but if you answered about an hour ago I would of considered you god, however you are great.
My device is still under warranty so I will go see what I can do on Tuesday!
If you would like full instructions on how to flash your phone I would be happy to help once its fixed.
Good luck with it. I have found all the best links from this site.
I also know one company that can unbrick the s2

[Q] Help - SGH-I777 in boot loop and it can't get out

I'm an admitted noob, but my hope is that somebody here will take pity and be able to shed some light on what I've done and how to fix it.
Here is a general high-level list of what I've done:
1. I attempted to root my phone with SuperOneClick (I think 2.3.3)
2. It hung one Step #7 (as I recall) for about 10 minutes.
3. I disconnected USB cable and reset the phone - it wouldn't boot
4. Started researching, discovered Recovery Mode, selected reset to factory.
5. Reset appeared successful, but then phone went into reboot loop.
6. Tried to access Recovery Mode again, but this time it came to different screen, saying "Deleting cryption meta data".
7. Tried flashing several times with odin and stock PDA's suggested in this forum.
8. Same behavior, so flashed CWM 4.0.0.2 (unfortunately it was for I9100)
9. Flashed new CWM 5.0.2.3
10. When I enter Recovery mode now and I select the wipe data/factory reset option, it just goes to a hat icon with a circular arrow and stays there.
Like I said, I'm new here and have already given up hope on recovering any useful data on my phone. I just want to get it working again so I don't have to buy a new one.
Thanks in advance!
In you item #10, that's a common mistake. The 5.0.2.3 version does not use the power button to select. Use the home softkey to select and the back softkey to go back.
Try to wipe data/factory reset again from this version of CWM Recovery, and then try flashing the one-click downloader return to stock in the "Return to the store or for warranty replacement" thread stickied in general.
Post your results back here and I'll try to keep an eye out to help, but I won't be on the computer every minute.

This guy is right. The power button is the menu/logo button in that version. The newer version changes that mapping though.
You'll likely need to flash the return to stock image. One of them is already prerooted, too!

Thanks so much for your quick reply and help. I followed the instructions you outlined and all went as outlined. Upon final reboot I'm back at Stage 6 in my original post. The original Samsung logo is back (which is a relief), but so is the incessant rebooting and upon trying to enter Recover Mode, I get the Deleting cryption meta data message and then more reboot loop.
Looking forward to your next suggestion(s) and a little sleep.
Oh, by the way, the wipe data/factory reset within CWM appeared to run properly but made no apparent change.

Tried to answer you this morning, but didn't hit the submit button until a few minutes after 8:00. Let me see if I can do it again.
You did a factory reset and then installed the stock firmware. Now try a factory reset again to see if that will clear the bootloop.
If that does not do it, then you may need to replace another part of the system. We need to know exactly what you flashed for the I9100 while you were trying to fix the original problem (point 8 in your list.) So far, you have flashed everything in the stock UCKH7 firmware except the bootloaders and the param.lfs. You may need to flash param.lfs next to see if that will do it. Is there any chance that what you flashed for the I9100 contained bootloaders?
...........
By the way, having Super OneClick hang on step #6 is a known issue, and the solution is posted in the Super OneClick thread OP as well as in the Library sticky thread in the development section of the I777 forum. If you had been better informed, you could have avoided this problem.

First, you're a true gentleman (assuming 'creepyncrawly' to be male) for sticking with me on this issue - Thanks!
To address your first point, I could't do a factory reset after this most recent flash because that dialog doesn't exist any longer. All I get is the "Deleting cryption meta data" message when I try to enter recover mode.
As for the I9100 flash, I used CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4 first which took me to 4.0.0.2 and then realizing what I'd done, flashed with SGH-I777_ClockworkMod-Recovery_5.0.2.3 which took me to 5.0.2.3, though the I9100 logo still showed during boot.
Thanks again for your help. I will "flash at will" whatever you suggest as at least I feel I'm making progress now.

The CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4.tar contains only the kernel zImage, so it doesn't flash any of the wrong bootloaders or param.lfs, so no clue there.
However, the message "deleting cryption meta data" seems to be associated with the lfs, so I would suggest that you try flashing just the UCKH7 param.lfs file using Odin3. Go to the Download Repository where you will find the Odin3 flashable tar of the UCKH7 param.lfs.

I successfully flashed the I777 param.lfs from your download repository. Unfortunately, with the same results. I still get the boot loop and when trying to access recover mode I get "Deleting Cryption Meta Data".
Would you suggest I try flashing the secondary boot loader or .pit files?

Well, I had a little extra time tonight so I tried a couple more things after my last post. I went back to the Download Repository and got the secondary boot loader (i777 UCKH7 sbl), flashed with that. No change. Then I got the full set of binaries (I777UCKH7-CL503881-Full), flashed that, and still no change. I think I've tried everything except the .pit and that appears the most risky so I'll await further instruction before trying that.
Am I running out of options at this point?
I had a similiar problem with the deleting meta cache data. I couldn't get it back to working order although I didn't flash pit either. Luckily mine was within 30 days so I gave up and returned for a new one.
Hopefully this deleting meta cache thing can be figured out to see what the cause is. Mine happened from a working rom browsing the web, not from flashing. So I believe it was from aftermarket charger creating some hardware problems to my phone, but not sure what it could have messed up.
If ya can't exchange yours, I hope you figure it out.

I have always understood that if a phone will boot in any way, or show any sign of life, then it can be recovered. Since you can still get into download mode, you should be able to recover your phone. However, since I am not an Android developer, and I don't really understand the low level workings of the phone, I can't offer any more suggestions myself.
You have flashed the complete I777UCKH7 software package including bootloaders and param.lfs, which also rebuilds the csc, so I don't know what is causing the bootloop.
You need to seek the help of someone more experienced. I have two people on xda in mind who specialize in recovering hard bricked phones, and both have a better understanding of the low level workings of the phone.
Adam Outler is a fantastic hardware level developer who published the unbrickable mod for the Galaxy S series of phones, and is currently moving into the Galaxy S II phones. I have heard that he wants an I777 to work on to try to make the unbrickable mod for our phone. He would probably not charge anything since he is using the phone to learn how to do it, but he might keep the phone for a while.
Connexion2005 of Mobile Tech Videos offers hard brick recovery on the Galaxy S and Galaxy S II series of phones. He also has a very good understanding of the low level functions of the phone.
If it was my phone, I would be contacting these two to see if I could get any guidance about how to recover the phone, probably Adam Outler first. I would try to pm them and I would try to get phone numbers and talk with them in person.
You are not hard bricked. And about the pit, that re-partitions the phone. But I don't have enough experience to know if partitioning could cause the problem you are experiencing.
Good luck moving forward.
Any chance flashing a ROM would do the trick...like Unnamed or SHOstock? Just thinking that maybe he's flashed so many things nothing is playing nice anymore. Just a thought, not necessarily a suggestion. ;-)
Also, how long are you letting it sit in boot loop now? It might be taking a while to rebuild everything...?

So, had you rooted and put a custom rom on prior to yours going south, or was it completely stock? What made you think it was related to the aftermarket charger?

Thanks for your thoughts. I had a similar thought last night and so let it sit through the night rebooting. Sure enough, when I checked it (roughly 8 hours) this morning, it was nice and warm, but still rebooting away.

Thanks very much for all your help! I'll try to reach out to these other gentlemen as well.
I've seen other people on these forums with the same problem, but unfortunately, every thread seems to end unresolved. I still hold out hope as I really don't want to eat the cost of the phone and start over.

I figured it was the charger because it was connected when it happened. Was driving home from a Christmas vacation, with maps navigation going, stopped at a rest stop surfing the web. Also on another thread that I read that had a similiar problem, they too thought it was the charger.
And no it was not stock, running unnamed at the time, (though I doubt that is the cause). Like yours I think, I could flash from cwm without success. Wasn't until I flashed stock with stock recovery that I got the deleting meta cache or whatever it is.

Any luck so far? I think I'm having the same issues. Although I can flash the stock rom, then a CWM .tar file and get into recovery. But no matter what I do, after boot, the phone starts boot looping.
You can see my thread in the Q&A section.

[Q] Help rooting and flashing GS2

Hey all,
i've read through many treads on how to do this but im getting confused as different threads say different things and there is info i think i am missing so i was wondering if you could help me as im noobing out and im confused as hell now. so basicly i have a stock standard Galaxy S2 with the Australian Vodafone ROM/OS/ whatever its called. Model is GT-I9100T running 2.3.5. so with all the info i have been reading the things that have confused me the most are
What version of kernel to use as there seem to be like 50 billion (may be exaggerating)
What is the "modem" that gets mentioned every so often and if i need it what one do i get?
How to use the Clockwork mod and how do i install it because i think the new ROM i want to install is the Cyanogen mod and it made me install a different root and the wiki for it was unclear when it came to the end of installing it
and then how do i install the Cyanogen Mod once i have done the rom.
i know there is a fair bit of info out there but all the threads i read are either incomplete or im just well....... yeah. Help would be amazing for this as the Vodafone OS is starting to annoy the hell out of me!
Thanks heaps!
To root your phone, go to this thread & find the kernel that matches with the baseband details in settings/about phone. Flash this kernel in the PDA section of Odin (DL link also found in this thread).
This will also install CW Recovery on your phone.
No need to go changing modems unless you have problems with coverage/data and you're sure this isn't a Vodafone coverage/capacity issue in your area.
To install Cyanogen, refer to the thread devoted to it in the development section of the board. Follow any installation instructions to the letter (there's a hint right there).
Bottom line, if you're confused/scared/not confident about rooting your phone or flashing a custom rom/kernel, don't until you are confident about it. Whilst these processes are relatively simple if you follow the instructions, if you skip things and don't do your homework first (there are no shortcuts, read, read some more, and keep reading until your eyes bleed), you run the risk of soft bricking your shiny new toy at best (and having to live without it until you fix it), or hard bricking it at worst, resulting in you having to pay Samsung to fix it.
Every rom or kernel I've come across on here has had absolutely simple installation instructions normally in the first post of the thread.

grr so using odin the way that the guide you linked said and downloading the kernal the way you and the guide said and following it I.E. booting odin and the connecting phone to the comp in download mode i get the line from odin "<OSM> All threads completed. (succeed 0 / failed 0)" and it wont show anything when i connect the phone yet when the phone is connected in normal mode it will show me some info in the ID:COm area, am i doing anything wrong? i tryed to post into the guide but i wont let me >.>
1) In settings/about phone what details do you have ?
2) Which kernel did you download from the CF Root thread ?
We'll go from there when you post this info.

ok sooo, baseband version is I9100TDUKJ1 thus following what i read i downloaded "CF-Root-SGS2_XW_LUX_KJ1-v5.0-CWM5" from the site
OK. Two ticks for that info.
So. You need to unzip the tar file from the zip you initially downloaded. Do not further unpack this. It must be the tar file you flash in Odin.
Fire up Odin. connect a USB cable to your phone, then plug it into a USB port. You must have 0:[port number] in the first panel in Odin directly under ID:COM on the left hand side in yellow. Keep trying different USB ports until you get this. This indicates Odin recognises your phone.
If it doesn't, you need to download Kies so you have drivers installed. If you do need to do this, make sure you kill Kies in task manager as Odin won't work with Kies running. We're only after the drivers.
On the other hand, if Odin recognises your phone as per the 2nd paragraph, click on PDA & navigate to where you have the unpacked CFRoot tar file & select it. From here, click on start & let Odin do it's thing. If it's successful it will show pass highlighted in green in that panel under ID:COM on the left hand side & the phone will reboot. Pull the USB cable & your phone should now be rooted.
To get rid of the yellow warning triangle when it boots, get a jig from eBay (search for Samsung Galaxy S2 jig or similar), they only cost a few bucks & can be handy if you ever need to return the phone for warranty service. There is another method in the CFRoot kernel thread to get rid of the triangle, but I prefer the jig.

ok so when i do this when its booted in normal mode it will appear in odin and be in the left box when i get it into download mode (start it holding vol down home) it wont show up in odin, does that mean im doing it wrong OR i am meant to do this in normal mode?
If you'd read the CFRoot thread you'd know the answer to this question.
6th instruction/bullet point - "Put your phone in download mode" :-/

yeah thats why im confused because when i do it in download mode it wont pick up the phone, does that mean im missing kies drivers? coz i can only get the phone to show up in odin when its in norm mode
ok so removed then reinstalled the drivers and was able to pick it and the install worked =D woot
So you got pass in Odin and you get the yellow warning triangle when the phone boots ? To check you have root (you should have), get Root Check Basic from the Market if you want to be absolutely sure.
Also if you boot into recovery mode (volume up/home/power buttons held simultaneously when the phone is switched off), you should get CW Recovery.
If you install Ti backup or any other app that requires root, if these work then you can be sure the phone is rooted OK.

ok so did that and then was able to install the new ROM, it froze for a bit and i thought that i bricked it but it works and its soooo much faster! thanks for the help only thing now is to fix the yellow triangle on startup! THANKS SO MUCH!
No worries Get a jig to get rid of the triangle/reset the flash counter & you'll be set. If you find the jig doesn't work, you're using firmware with the new "locked" bootloader. If this happens, flash the old bootloader from this thread (there's a paragraph in bold red text about halfway down & a link to download it) in the PDA section of Odin & the jig should work.
So far as installing other roms/kernels go, as long as you follow the instructions to the letter (some require flashing the rom twice in a row without wiping like CM for example), you shouldn't have too many problems/shouldn't brick it.
First thing you should do now that you've rooted it/installed another rom is to make a Nandroid backup in CW Recovery, then you can get something like Titanium Pro & backup your apps & so on. Good practice is to make a Nandroid backup before your flash a new rom/kernel, that way if anything goes wrong, you can restore your previous setup in a matter of minutes with no harm done.
Also, get Hellcat's kTool from the Market & backup your EFS details ASAP. Keep a copy of on your external SD card (if you have one) and also keep a copy on your PC/external drive/or a CD/DVD/USB drive.These basically contain the IMEI of your phone & allow it to work with the network. Occasionally people find the EFS details get fried for various reasons and this can mean your phone no longer works with your network provider. Obviously if you have a backup and this happens, you can restore it.

[Q] Galaxy S2 does not start after flashing PIT

I am new with the Android,
i have a i9100 galaxy, which i have flashed and other phones also (for freinds) several times with new firmware 2.3.4
Bubut this time i was trying ICS on my s2, after installing ICS with odin the phone did not perform well and it was not upgrading the market to google play, so i decided to reformat and install from scratch,
I entered the recovery mode and formated all options then into download mode and i tried to install ICS and the install was not successfully, then i do not why! i decided to reflash the pit, all went well and after the flashing it shut down and never came back on again
Now i have an expensive brick.
It does not start at all (i have tried download mode, recovery mode, remove battery etc.. no luck) it is totally dead
Any one Help !!!!
Thank you
Alot of guides said never do the .pit repartition because you may hard brick your device. Send it to samsung service center for repair.
Sent from my GT-I9100 using xda premium
Seriously, why cannot people understand that flashing the PIT file is totally unnecessary and will more often than not, end up bricking your device?
You'll need to send it to Samsung for repairs.

Thank you for the quick reply, i was hoping for a different answer
i have read that that a JTag cable might help i will try later and get back with results
JTAG repair equipment is expensive & takes expertise to use. You can send it to someone who does JTAG repairs; this one in the US does them for $50 USD, no doubt there are others you can find via Google.

Same problem here , after flashing PIT my phone goes black with no respond at all , no charging .....
As stated on other link, sounds like youve both flashed the wrong pit file and the only repair for this is JTAG service.
Flashing a pit is safe, so long as you do it the correct way and flash all the accompanied files, ive flashed samsung pits and never bricked before, there shouldnt be confusion because samfirmware release a lot of stock roms with the pit file and theres plenty of guides to flash them and there is only 1 pit file by samsung for the i9100, its really up to you guys to make sure you are using the correct file when flashing your phones, if you dont know then you should never touch anything more advanced than a 1 file package.
Hope you get them sorted but i think youll have problems.

Bootlooping - even after flashing Siyah

A couple days ago, my Galaxy s2 i-777 (unrooted stock) would not start up past the splash screen. Today, I finally tried to do a factory reset in recovery mode, and there was a message about not being able to access some csc folder. My phone remained in bootloop, and when I tried to get back to recovery mode - I would see the dreadful "Deleting Cryption Meta data" message.
I proceeded to try the instructions in this post : http://forum.xda-developers.com/showpost.php?p=27368753&postcount=7
I managed to flash my phone with CWM5.0.3 using Odin (The PDA option - is that right?) It changed my splash screen to one with 9100 on the front, and a yellow triangle. My flash counter was also incremented to 1.
I then attempted to flash with the Siyah kernel again using Odin (with the PDA option). The good news is that I can now get to Siyah's Recovery mode, but the phone is still bootlooping. And I'm pretty sure my flash counter has incremented again.
Here's my difficulty:
1. I want to find a way to get my images/videos off my phone. (We just had our first kid and all his photos from birth are in there :|)
2. I plan to get a jig, reset my counter and restore to stock unrooted. Is this still possible?
How do I do these two things?
Thanks so much everyone - I've really appreciated all the posts I've been reading for assistance already!
=======
So I figured out how to get my photos/videos off - amazingly, even after a factory reset - they are all still in my phone! I decided to re-flash CWM as suggested in the post linked above. Went to the recovery menu and did a clear data/factory reset. I was about to try the format sd card option (which admittedly I had skipped earlier because I was concerned about losing photos/vids) but then decided to try mounting the sd card instead. Then I reconnected the phone to my computer and was able to use it as a USB storage device, and view all my files! Now I'm copying over my app data, pics and videos.
I just ordered a jig off amazon, and hopefully I'll be able to reset my counter and return to stock. I'm still not sure why my phone is bootlooping though. Any ideas?

Happy to see this my dude, glad you got them back!!!! Congrats on the new baby good times! I can't really be of help but this thread has some more info you can read maybe it can help you.... The link you posted is posted in post 2 via creepyncrawly but there is more info in that post. Maybe your problem is just a random hardware failure but always best to have all the info you can get..... GL if you have more questions creepyncrawly is the coolest dude and will help you!!!
http://forum.xda-developers.com/showthread.php?t=1738663 Some info 4 you
EDIT Once you get your jig that should clear the flash counter and put the phone in to download mode then you could flash a stock package to get your phone back working!!! Of course depending if it's a hardware problem....
http://forum.xda-developers.com/showpost.php?p=18859438&postcount=199 Here the link to the stock package or rooted stock One click Odin
There is also another way to remove the triangle and the counter via an app i have used it several times and it works great here is the link for it

You are correct but, he would be flashing KH7 GB so the jig would clear it.... Triangle Away works on ICS and has risks "!!! THIS IS A DANGEROUS OPERATION AND COULD POTENTIALLY BRICK YOUR DEVICE. PROCEED AT YOUR OWN RISK. A USB JIG IS PREFERRED IF YOU HAVE A WORKING ONE !!!" (and by brick I mean brick - only a board replacement or a JTAG unit will be able to save you, don't mess with boot(loader) stuff unless you *really* mean it!) via Chainfire you're better never tripping the counter......

AFAIK, this tool only works with ICS.
Please inform.
Is it a boot loop-where your screen will go black attempting to continue booting, then re initiate the previous animation? Or just a failure to boot-where it's just hanging on an animation with no black pauses to indicate any kind of process completion?

It a boot loop if the phone tries to boot over and over again, only reaching a certain point, usually the initial (kernel) splash screen, then restarting again. However, many fail to boot scenarios are commonly lumped into the somewhat generic term boot loop.
Poor wordage on my part lol, that differentiation was what I was trying to ask the op

I have used it with JB and had no problems I do not know if it was intended to work with JB but it did on my sgs2 ( I guess I just got lucky ) I have used it 3 times on ICS and once with JB and While I will admit it is VERY RISKY I too would recommend the jig but was just giving another option
