I've tried to look for this problem and haven't found anything similar. If it's already been addressed please direct me to the previous thread, if this is in the wrong place please move it.
I rooted my Galaxy S II a while ago and it's been working great. I wanted to try Cyanogen mod 7 and so I followed the instructions on their website. Trying to use ROM manager gave me a weird error message telling me that there was an invalid signature or something, despite toggling everything and wiping the cache to turn it off. So I followed the "method via recovery" instructions. I did everything exactly as it is there, including the Google apps stuff, and it all seemed to work perfectly. Then I rebooted it hoping for it to boot into CM7, and instead, when it turns on it goes to the screen saying Samsung Galaxy S II with the yellow triangle underneath, and stays there. Every time it turn it on it goes to that screen and doesn't change. It's now been like that for half an hour. I can start it up into download mode, and I've tried flashing zImage to it again, but no change.
I have a NANDroid backup (it's backed up with CWM anyway), and I've copied the backup to my computer, but I have no idea how to apply it when the bloody thing won't turn on.
I'm using Linux with Heimdall (the cross-platform Odin clone).
Please help me. Unfortunately I have no internet in my flat so I won't be able to see any advice until tomorrow unless it;s given in the next ten minutes. God I really hope the thing's ok.
Hi
Do you have jigg? ( if you don't have it buy it from ebay or ask some friend of you )
With jigg you can enter download mode and then flash the stock rom.
Pull battery, wait 10s, then boot while holding power+vol-up+home. This should get you in recovery. Then restore nandroid.

I can't believe it was this simple, I knew power+vol-down+home got tme to downloading but I didn't know that got me into recovery. Everything's recovered now.
Thank you Dutch people!
hello xda. been browsing for a couple weeks, but finally registered today.
I have run into a problem I would like to try and solve without having to go through my insurance or carrier. my phone bricked itself after only 16 days, with 0 modifications on it. it was factory stock still. let me describe what happened, and what I did:
1st problem: I was using my online banking app (reputable bank), when the app minimized to the main screen; however, nothing OS related loaded. the phone just froze. only the wallpaper was visible. I tried powering it down, but it wasn't responding, so I pulled the battery, and put it back in. I powered on the phone, it loaded the SAMSUNG screen, then went to the Exhibit II 4G page, but then it stopped. it failed to load past the Exhibit II splash screen. no matter what I did, it stayed there. I googled for hours, trying various things, until I finally found this site with a stock rom setup.
2nd problem: I followed jocala's guide for flashing it, using Odin 4.43, and after it finished flashing, I got a "Firmware upgrade encountered an issue. Please select recovery mode in kies & try again." so now I have been googling this issue, and I cannot seem to find anything on how to fix it. I don't understand how my phone can just brick itself while using a banking app that i'd been using since I got the phone.
any help would be appreciated
also, if this isn't the forum for it, feel free to move it. this just looked the most appropriate seeing as there wasn't a board for the phone specifically.

Howdy, DBNP,
The Exhibit II is pretty much unbrickable...you won't need to resort to esoterica like jtag
The guide in the Exhibit II Wiki usually works out well. I'd try booting into stock recovery, doing a data wipe, then install stock with Odin. The Wiki has the links to the files you need. BTW, I didn't write the Odin portion @ the wiki; I just hosted required files when the links went stale.
Easy way to start recovery
* Pull the battery from your phone.
* Connect phone to your pc via usb.
* Press & hold Volume-up
* Insert battery
Once you're back up and running first thing you should do is install Clockworkmod. HTH, & good luck.
I cannot get my phone to get into recovery mode, though. if I press volume+up, the phone simply displays the firmware error message. thus, I cannot do a data wipe.

Sorry if this is redundant, but this was with:

This has never failed for me. IDK, Perhaps your earlier Odin try wiped the recover partition. Can you get into Download mode? (hold Power-on Vol-Down)
I can enter download mode, but I cannot enter recovery mode. volume down gets me into download, while up gets me the error message. I cannot get to that menu anymore.

Are you saying that you get an error when you press Vol-Up at the initial "Warning!" "A custom OS can cause..." screen, the initial download mode screen?
when I press and hold the vol-up sequence, it takes me to the initial error of "firmware upgrade has encountered an issue..."
when I press and hold the vol-up sequence, it takes me to the menu where it says custom OS etc., press up to continue, down to cancel (restart phone).

OK, that's good. That tells us that your exhibit2's /dev/block/mmcblk0p5 partition is undamaged. AFAIK Odin when properly used, can flash a new rom to your phone. Please try again, following the instructions in the wiki, reading carefully, downloading any files that you need, if you don't have them. Please walk through the wiki procedure to reflash stock from Odin, this procedure has worked for many,many people. Keep careful notes, you may be an edge case for some reason.
I'm posting links to this thread in the discussion threads that we use, since we're not allowed a forum. These threads get the most attention.

I think you and your friend did it wrong. You should try again, following the wiki carefully.
we re-did it this morning step-by-step with no new results. we tried three times.
odin does its thing successfully, then when it goes to reboot, instead of going into recovery mod, it just goes to the firmware upgrade issue message.

Sorry to hear it. If Odin won't fix your phone and you've only had it a few weeks, I'd return it. I've linked your thread to our discussion threads, perhaps someone else has an idea.
that's the issue. because I have tried to flash it via odin, they're saying they won't take it because of the firmware upgrade error that keeps coming up. :/
because they won't take it, and the normal flashing to stock method isn't working, what do you think I should do next?

I don't know who "they" are, but the chances of anyone at a T-Mob store or a Walmart knowing you touched your phone with Odin or even what Odin is are practically nil. "It's three weeks old, I turned it on and it doesn't work. Gimmie my replacement."
Or seek out a repair service to reflash your phone.
all right, i'll take it back and get a different rep. thanks for your help, though

go into recovery and do a factory reset then reboot from recovery.
i was trying to root a phone for someone and after odin completed it said it had failed.
the phone is a telus samsung t959d running froyo.
I followed the instructions from (I would post the url for the link but i am not allowed to.)cyanogenmod's wiki, after it failed I rebooted the phone and it got stuck on the screen in the attached pic. I have tried to boot back into download mode to no avail. From the screen it's stuck on I cannot get any tool to register the device as being present, adb, heimdall, zdiag, etc... I even tried fastboot out of desperation.Before I used odin I tried to get the phone to boot into the bootloader but it only ever went to either recovery or a normal boot and I tried every button press combo I could think of and found and nada.
Even running adb reboot bootloader just made the device boot normally. I think that if I could get it to boot to fastboot usb i could then try fastboot. I am new to rooting devices and have successfully rooted my HTC EVO3D and got s-off and simlock removed for any carrier. So I do know how to follow instructions properly, why flashing the recovery.bin failed I don't know and every fix I seem to find says BOOT TO DOWNLOAD MODE. if I could do that I wouldn't be having this problem lol. Anyway can someone please help me figure this out. Thanks. ANd if you need any further info please let me know. I don't want to have to give my friend my phone due to a software issue.
And YES I did pick PDA not anything else.

I kept reading other threads and sadly I din't pully the battery first before disconnecting the usb and repartition may have been checked as I see that it does the as default for my version. Also i turned off ODIN as I was hoping a reboot of my computer might help. I will keep trying to find an answer till someone gets back to me. this post may not even show up if I can't do a second post if no one has replied first.
Everyone was a nub at one time wasn't it FUN hahahahahaha sob cry

I tried a jig and that didn't work. There must be some way of getting the device to give up on completing a task i no longer can give it due to ODIN being shut off.
Why is it that the "how to root/unlocks" never have the "if x fails then do these steps etc..." Had the how to had "pull the battery before disconnecting USB and don't reset or shut off ODIN" I wouldn't be in this mess. I realize that it's user beware but a few important steps like that in case of a fail would go a long way to you guys not shaking your heads. Instead of "silly nub hahahahahaha". No offence but I get that a lot and try to remember that when I teach someone how to use a computer. I am new at phones not at everything.
Further Developments Please can someone help?
I was giving someone a new memory card and they had a Samsung SGH-I896 it has an EB575152VA battery and the one I have the T959D has an EB575152VU battery. I exchanged my battery for hers by accident somehow and when I plugged my phone in it didn't go to the phone triangle computer logo screen it booted to recovery and said it couldn't charge the battery and kept rebooting to recovery. I got my battery back and it booted back to the phone triangle computer logo again. Grrrr....
The other thing I saw while the recovery screen was an error message that said
Code:
E:/data/fota not accessible
(may not be 100% accurate I don't have the battery to check right now but can get it again if need be) anyway I now see that there may be some light at the end of the tunnel. i have the correct stock firmware for the device I tried flashing it while in recovery but the phone kept rebooting before anything got done. My question is how can I get the dang phone to stop asking for Odin and go to recovery so I can flash stock firmware and ROM back to it? As I cannot as far as I know give it what it wants because I reset Odin and nothing seems to see that the phone is connected to the computer. I am going to try the other battery on a full charge to see what that does.
I am new at all this and want to get it fixed. I cannot afford to send it off to a service center and besides that I want to do it myself as I want to become a developer and droid technician. I would gladly donate to anyone but am still trying to get Google to accept my pay-as-you-go credit card and I don't have PayPal either. Which is really frustrating when it comes to giving back. I posted a Q&A on how to without PayPal or CC but as of the last time I checked no one has gotten back to me about it.
The CyanogenMod guide is flat out WRONG. I've tried to change it, but anything I do is reverted in an instant. I also tried to use it to install the ROM only, ended up bricking my phone and it took me hours to unbrick. That's how I became acquainted with XDA.
So, to get this straight:
1. you're using the stock USB cable
2. you remove the battery
3. you hold volume down
4. you plug in the usb cable
5. after a few seconds, you release volume down
6. the screen does not display a yellow triangle with an android

That is correct. If you think that my idea below is a bad one or if I downloaded the wrong firmware package please let me know and /or you have a fix that will work? ty
I have though come up with an idea that may work. I am going to charge the "wrong" battery in erm the right phone lol and then use it to trick the device into booting into recovery instead of the cellphone triangle computer (CTC, for want of a better acronym) The I896 battery ends in a V not an ? (sorry can't rem don't have it on me) from the I896 model I think it is, plugging it into USB with the power off sends it to recovery with the "battery cannot be charged " message instead of the CTC screen.
I tried it but the charge in the battery was too low and rebooted. I am hoping that with a full charge (as long as I don't power on the phone first as this will make it go to CTC logo again.
I am hoping that I can install the update.zip that I made by first unzipping the T959UVJFD_firmware.tar I downloaded then unpacked and then repacked into an update.zip as I don't think that it will read the package as a tar file and if it's not called update.zip The recovery is still stock. If I get the phone working I am not going to try unlocking and rooting it again. I will just post two separate adverts one as a carrier locked device and the other one (higher of course to cover buying the unlock from Telus) as carrier unlocked and then I will buy the unlock code if the blah blah you get the drift. sorry for rambling on.
oh and I can't rem if I said this or not, In recovery it "E:/data/fota not accessible" I don't know what that means yet I have been busy with other things and haven't looked it up yet.
Since you can get into at least some version of recovery, your bootloader is intact and you should be able to unbrick it. You ought to be able to get into download mode using a download jig. You can get one on ebay for a few bucks or you can make one yourself. There's a guide floating around here somewhere that lets you make one from a microusb cable.

Okay, So I am as NOOB as NOOB can be,
I got a used SGS2 (Bell/Virgin), I am on Telus so I figured, how hard can it be to unlock it instead of paying some dude to do it for me? (First mistake, and have been humbled every step of the way since!...)
Anyway I will try to keep this relatively short (it will be difficult)... ...I read a few things online and saw that I needed ODIN and a Rooting software, I originally used SuperOneClick, and to download the right insecure kernel to match my original one etc... ...problem is I obviously didn't read nearly enough when I started because I was almost done and then there was a hiccup when SuperOneClick said that I needed to enable SU in Kies. So I decided to go into Kies to try and do so but the instructions before I started Rooting said to put the phone in USB debugging mode. Apparently Kies doesn't see the phone if it is in that mode. Well by this time I can't get past the logo screen and this is where my downward spiral begins.
I then tried to unroot the phone to go back to stock but didn't really know what I was doing and then I read something about the cache needing to be wiped and then after that I read that maybe my OS was wiped. So at this point I did lots of reading (what I should have done in the first place) and most of anything useful I found was on XDA so that is why I am here. It seemed like yes, in fact my OS was wiped because of one of my not so S-M-R-T actions. So I fumbled through and found the right OS for my S2 and I had ODIN going strong and I had the OS loading, the green bar getting bigger in ODIN and the blue bar working it's way across the screen of my S2...I thought "finally!!, I rock!!"... ...then for some reason everything stopped! I had seen in a post that I had to uninstall Kies before doing anything, which I did...but I didn't see until after the fact that my anti-virus likely interfered (I didn't disable it for the process before I started).
At that point of course I was left with a phone that says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
So then I was afraid to try anything else because many say to steer clear of Kies and also I had read that I may need a USB jig to be able to get it back into download mode because all I was getting was the "firmware upgrade issue" screen. I did make a USB jig with a resistance of 300K Ohms and I *can* get the phone into download mode. (Though another concern is that when I plug the USB jig in and it brings the phone into download mode, the counter is not reset and I read that that was supposed to be reset by the jig.)
So last night I got brave and decided to try and run ODIN and to have another attempt at installation of OS. Now I can get ODIN to detect the phone, but I put the I9100MUGLD3_I9100MBMCLD3_I9100MXXLD3_HOME.tar.md5 file into the PDA section of ODIN and it starts and gets to the part where it says loading firmware or something and then bootload.bin and it stayed like that for like, an hour and then I gave up, fearing that I am just going to screw it up even more.
So now I decided that I am not even close to knowing what to do next but every time I found anything to move forward it was on this site so I figured I may as well join the site since I have been here so often. Now I am hoping for some kind of miracle...so, in advance, please please please and thank you thank you thank you all for your input. (Sorry for the length of this I just wanted to get all the info I could into this)
Its quite a long story and didnt bother reading it.
If you can still access your phone via odin at downloadmode. Flash a stock firmware for your device and it should fix if it is just a soft brick.

Sorry for the length of the story, I thought there may be alot of useful info mixed in with the useless info... ...when you say use stock firmware do you mean the kernel or the actual OS? I tried loading ICS onto it (which I thought was stock but I may be wrong). Is it supposed to be gingerbread or something else? Also where would I find a good file for it.
Thank you again for any input, very much appreciated!
Hey ,
I also have a Virgin Samsung S2 i9100 and the first time I tried rooting it, it got stuck on the screen with the yellow triangle and wouldnt move at all. I believe it was bricked?

Thank you all so much for your help, I could not get it to work after several tries, I even tried three or 4 different USB cables and ports on my PC and still no. I read on another thread that one person tried another PC and it worked so I tried my friend's laptop and it worked!...my SGS2 boots up and all that now! Very very happy thank you all.
Hi everyone,
First of all, thanks for all the help/development done here, it is really awesome. I am new to rooting/rom so, I've spent a lot of time reading forum threads and looking at people's issues and it's been really helpful.
Yesterday, I spent all day trying to update my Bell Mobility Samsung Galaxy S Vibrant GT-I9000M from Froyo 2.2 to 4.2+
I sucessfully rooted the device, installed SpeedMod kernel(with Odin 3.04) and got CWM Recovery working when I restart the cellphone.
Afterward, I tried to update with different ROM(CyanFox, CM11, Mackay OmniROM...) but always got Status 7 error at CWM. So I figured I'd try to upate to a recent Kernel and installed GearKernel_JBPlus_Vibrant_1.0.3v.tar trought Odin. The phone got in an installation loop. Here is a poor webcam photo of the error(sry couldn't get better) : http://i.imgur.com/L3b0RmF.png. It says something like Estimating(?) volume for path [grep], Can't mount grep, Installation Aborted. Restart, splash screen, installation aborted, loop.
I had this loop at other occasions trying to update Kernel. The solution had been to put the cellphone in Download mode and reinstall Speedmod Kernel with Odin. This is what I did again.
It allowed me to get in Recovery mode but I couldn't go passed it. Attempt at restoring backup didn't worked. So I decided I'd go back to everything stock and followed this thread http://forum.xda-developers.com/showthread.php?t=1047087 and used Odin with the PIT and TAR files.
This got me in my worst position so far. If the cellphone is plugged, it loops between dark screen and the little "loading thingy" before the battery, but nothing more, no battery charge. If I try to open it without the plug, it display the GALAXY S GT-I9000 splash screen(which is weird cause I'm using I9000m) for a couple second then goes dark.. Then splash screen.. then dark... pretty quickly.
I can go in Download mode but I haven't succeeded to get in Recovery mode. I have adb on my computer but I haven't been able to call anything from it at the point I am.
I have found different threads showing different solution for various problems but I feel like I tried enough and I'd like to avoid bricking my cellphone so I decided I'd make my own post detailing the steps I took.
What should be my next step to get out of this loop? It seems like I only have Odin/Download mode to help me.
Thanks again.
If you have the gt-i9000m that is not the vibrant. The vibrant is the sgh-t959. Thats probably your problem
