You're definitely not screwed. I would just keep trying to install that Odin flashable CWM, there's no reason it should fail. If it keeps failing though it's most likely a faulty data cable, so try it with a different one.

But you can still try to mount USB storage from the CWM you already have installed and transfer a different ROM zip onto your internal and flash it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Mike:
Your not screwed. For all intensive purposes you are in download mode. You could flash stock 4.0.4 and then flash the cwm 5.8.1.3 tar. From here do all the wipes I described and flash cm9 nightly followed by gapps.

Are u sure u followed all directions properly in his thread for installing cwm? You only have auto reboot checked and PDA where you selected the tar file?

You said you tried the wipe caches method I described but did u flash the cm9 nightly and gapps after the wipes or did u simply reboot upon completion of the wipes?

yup i followed the instructions correctly.

yes i did check only "auto reboot"

i wasnt able to flash cm9 nightly because that isnt there on my internal sd. but i flashed rc2.

this screen came after i tried to use odin.

anyway im now downloading stock and trying out what you said now.

thanks for instilling hope :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plwalsh88:
If Odin keeps failing it's almost always due to bad communication between the phone and computer. Which means to either try a different USB port (definitely one directly connected to the motherboard) or try a different USB cable all together. But you're in no way, shape, or form bricked. Something will work.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
I changed the USB cable and port and tried to flash the stock ics image. odin still fails. this is the message i get:

I just thought of something. I messaged a friend to ask if the following will give u access to internal storage from cwm while on PC. I am 99.9% sure it will but I haven't personally used it. In mounts and storage in cwm there is an option entitled mount emmc. Emmc is internal storage. Wait a min and let me see if he messages me back. From there u can move either a stock cwm flashable firmware to internal (can be found in Vincoms everything root) or you can go on and move the cm9 nightly and gapps to internal. From here u can attempt to flash after doing the wipes I describes previously. This is not a complete fix as u will still want the different cwm and ensure the integrity of your device. We are simply looking to get you booted up by doing this.

Wait a minute and let me see if I get a response.

Edit: I got a response and it should allow you to access the internal storage from your pc as I described

Are you using front end or command line with heimdall?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onealvideo:
Mac and CWM

You mentioned, from my Mac...

Are you on OSX Lion by any chance? If you are, there are KNOWN ISSUES of failed flashes. Also, if you are trying to install via Heimdall and you have Kies installed there are known issues there as well.

If you are on Lion, my suggestion is to install a Windows VM via Bootcamp or Parallels. Follow the sticky in Vins Noob Thread to flash to stock.

Install appropriate drivers, ODIN version as stated in sticky.

If you are on Snow Leopard, you may have to uninstall Kies as it blocks some things from working properly in Heimdall...

If you go the PC way of flashing CWM it works very well. I have sk8rwitskill's Touch 6.0.1.0 installed and it works beautifully!

Just go slow and try to get to a PC to perform these functions as the Mac way is just not really supported that well...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
yes i have a osx snow leopard and i was using heimdall command line. also i had kies but it wasnt running

its on my mac that i tried to it initially and i guess this is what screwed up.

Towards the later half, i got hold of a PC and tried my luck with ODIN which is when i started getting that "firmware upgrade encountered an issue..." message, with no access to download or recovery mode.

Now I am pretty much stuck i think.

:(
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
just to add some more info:

this "firmware upgrade encountered an issue..." shows up even when i simply plug my phone for charging. the default battery screen is also gone.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] hechoen:
Put the phone in DL mode plug it into your MAC and open command. Type

heimdall device

If it shows your device then you can flash both a recovery and a kernel from there.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onealvideo:
Ok...

Can you get into download mode at all?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
i am not able to go to the traditional download mode.

after i perform steps for the download mode, i get into "firmware upgrade encountered an issue..." screen

at this stage, on my mac, when i say "heimdall detect", it does say "device detected"
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onealvideo:
D/L Mode..

When you say traditional Download mode, what do you mean by this?

Are you holding the correct buttons and plugging in your cable, etc... per the directions in the Sticky?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] hechoen:
Unzip CM9 then copy the boot.img to the folder where you have heimdall. Type

heimdall flash --kernel boot.img

Then DL the recovery you want to use and unzip it. You'll see a recovery.img file. Place that in the folder where you have heimdall installed. Type

heimdall flash --recovery recovery.img

Once that's done just reboot recovery and mount usb storage. Put whatever you want to flash there then flash it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
awesome!

now i was able to flash the boot.img.

Can you suggest me which cwm version i should download and from where?

switch off phone. remove battery and replace.

hold volume up down and power keys for a while.

unzipped cm9 zip and did "heimdall flash --kernel boot.img" from my mac

now the phone finally rebooted with samsung sign

downloaded cwm 5.8.1.3 and extracted recovery.img

did "heimdall flash --recovery recovery.img"

odin only works for windows, is that what u where on.

this is the third time i seen this error in a week, dont know yet how newbs are getting this nand write error in odin.

could be user error or a unsupported flash to this phone like "ClockworkMod recovery v2.5.1.3 - voodoo lagfix " ive never seen that for our phone.

it seems most of the problems are that they bought the phones used, so it could be a previous problem w/the phone with a bad partition that will not get written too, its just weird that these problems are popping up lately.

read my trouble shooting odin section in my 2nd link in my sig, and yes u have to eliminate every possible problem in that list, you have to be on a windows machine.

get another cable

follow my instruction in the 2nd link in getting into odin/dl mode, if holding both volume buttons fails into getting into dl mode try only the volume down button

But i can connect to the my mac and using heimdall flash boot.img even with this screen. then i get back the samsung screen

i have a feeling that this "clockworkmod voodoo lagfix" that was there on my phone when i got it is the root cause of all the problems.

If you wanna flash the stock tar from heimdall it might be easier to use front end. That said what your trying to do should work.

Have you tried forcing it into recovery with ADB yet?

it looks like the reason they sold you the phone was they could not change the rom anymore because they flashed that lag fix file

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plwalsh88:
So are you sure that you actually have an i727 Galaxy S II Skyrocket? Voodoo lagfix was from the old Galaxy S days, such as the Captivate. And it converted the file system to EXT4 to reduce lag. It was a kernel mod but could be enabled/disabled through CWM, which is why your recovery shows those words at the top of your screen (as my Captivate CWM did). But that is no longer needed on our phones, and it hasn't really ever even been mentioned in this forum. So either the phone is not a Skyrocket, or the previous owner had no clue what he was doing, which is entirely possible.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] taraklina:
hi vincom and plwalsh88

yes the phone is indeed a skyrocket (it has that written under the battery etc). also it was awesome while it worked.

the partition table does say "read only" for the "RECOVERY" part which is probably why i am not able to move away from that voodoo thing and update to a cwm-5.8 for example.

Do you think the samsung guys will be able to repair this? i know warranty wont apply but paid service?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] plwalsh88:
Hmm that is interesting. I wonder what the heck that previous owner was doing. I'm not entirely sure on how you would fix it, but I feel like there has to be a way. I also don't know how the process works with sending it into Samsung but I have definitely heard good things on it. Hopefully someone else can chime in that may some ideas!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] vincom:
the link for the brick repair company would be cheaper, u can try calling samsung and get a quote, or wait and see if someone knows how to write to the nand or efs partitition or an adb expert

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] hechoen:
Have I mentioned ADB? If you can get it up and running you can change permissions for boot as well as recovery with it. You're not bricked. Why recovery won't write for you I have no idea.
