[Q] Tried to restore back to stock and it's just hanging on boot - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hey everyone, I've done some searching but I can't seem to find what I'm looking for. I was having a problem with my CM10 installations so I decided to revert back to a stock rom and start fresh.
I used odin to flash "I727UCLF6_I727ATTLF6_I727UCLF6_HOME.tar.md5" (which is supposed to be the stock ICS rom for at&t) and everything goes great, but the phone now hangs on the "Rethink Possible" AT&T logo. I've let it sit for about an hour so I'm pretty certain that nothing is going to happen.
I tried doing the same thing over hoping that maybe it was a bad flash or some kind of fluke, but came back to the exact same problem.
Any suggestions here would be phenomenal! :silly:

Reboot into recovery which will be stock recovery factory reset 3x and wipe cache 3x reboot and it will come up.

Yep you guys were right that did the trick! I didn't even think of it. I meant to post this last night when I actually did it but I fell asleep.
Do you know what exactly the phone is doing (or trying to do) when this actually happens to cause it? Just out of curiosity.
Thanks again!

Only way to find out is connect a debugger. Android SDK, ddms.bat

I'm not sure exactly but I have had similar issues with getting stuck in a boot loop. Usually formating and factory reset and a fresh flash did the trick.

[Q] reboot loop

My g2x keeps rebooting over and over again! This happened after i mounted it to my pc. it tries to read my sd card then just reboots over and over again. I have nv flash and tried to restore old back up but still does it. can any one help im thinking i need to flash stock.
you need to do a factory reset if your nandroid backup doesn't work. if that doesn't work reflash the rom.
I already did a factory reset and wipe and tried to re install the rom. it just continues to reboot. It starts up and if quick i can get into my lock screen and access things but within seconds it reboots and continues to do that
What rom are you using?

I was on a stock rooted rom when the problem happened. so i then i did a restore. when that didnt work i reflashed the stock rom that was posted on forum. i think it has something to do with my internal memory which i cannot access. this all happened when i was trying to back up my sd card while in usb and it just got an error when i unplugged it enless reboot.

I was hoping it was something simple like undervolting with a custom rom. I wish I could help. It sounds like you tried everything I would recomend. Maybe one of the real Android techie type guys can help you. I am still learning myself.

Thanks anyway! I even when as far as to re-flash stock recovery and then try to factory reset it but still did not work. I just dont know what the heck happened. So today I went to t-mobile and they r sending me a new phone and for know I have a loaner 10 days until I get the new phone they said it was backordered. oh well

My phone is soft bricked I think.

Ok, I flashed something that wasn't for my sgs2 skyrocket and when I did it nothing happened, then when I rebooted it it seemed ok untill it kept freezing, no sound even on full val. I cant call because I cant here the other person and that it freezes on every app I open it takes like 2mins to open or a force close comes up. Well I have flashed back to stock using odin but still the same problem. I dont know what to do? Any thoughts about fixing this?

If you have flashed back to stock, and are still having the same issues it sounds like there may be a hardware problem. Did you do a full clean flash back to stock? (system wipe, clear the dalvik)

Why would you flash something not for the Skyrocket?
Wipe the phone completely, as in all data, the system, caches, and repeat that wipe three times in recovery, then power down. Go into download mode and restore to GB stock (yes, all the way back), then use Kies to do the ICS update and stay stock for a few days to make sure everything works after that.
If it's still not working after that, your hardware is jacked. Restore the thing back to GB, pull the cord out during the ICS update on Kies and finish the job. Hope you're still in warranty; if not, I hear you can get a used Captivate for $60 or so while you learn not to flash stuff for the wrong phone.
in stock recovery wipe caches and do a reset, if still a no go, install cwm, wipe caches and reset x3, reflash stock firmware with odin again, perform a reset, if still a no go then hw malfunction
Well someone's lazy...

You just flashed it back? You're not making any sense. Post a link to the ROM you flashed or we can't help you.
I flashed the stock rom.

[Q] Oops I Killed It

I have a rooted and unlocked GS3 with liquidsmooth running on it. I tried the encryption feature which turned out to be a horrible mistake, every time the phone locks it turns off then restarts(Which I am pretty sure it isn't supposed to be doing) and now I am stuck in safe mode hell with a phone that keep restarting, should I just reflash it, or is there a way to fix this issue? Sorry if this is the wrong forum, I am rather new.

Odin back to stock and reroot, easiest way to solve the problem
Sent from my SCH-I535 using xda app-developers app
You can try to reflash the ROM to see if that works. Don't forget to do factory reset when flashing. That should get you back to factory settngs of the rom and reset your setup including the encryption mess.
Alrighty, thank you both for the help

ODIN failing to return to stock at movinand.bin

Yesterday my Droid Charge running Tweaked 3.2 would not boot, it would get past the samsung logo and start the boot animation and then turn off. Booting into recovery, several things were not mounting, was not able to wipe Dalvik cahce, only regular cache.
When I try to ODIN back to stock with PIT, it always fails on movinand.bin
I used Samsung PSTLite as well with the same result, failing on movinand.bin
I have tried flashing to ED1 and EP4.
I can flash ROMS such as Tweaked that do not have movinand.bin, but the phone does not start up at all afterwards.
Download mode still works.
What can I do??

Have you tried a data wipe/factory reset via cwm?
Sent from my XT907 using xda app-developers app
Yes, I can flash and boot into CWM, but wiping factory data does not do anything, it also shows multiple "error mounting such and such" messages

Try to re-PIT only.
Sent from my SCH-I510 using xda premium
What am I supposed to do after re PIT'ing? (which I have done, sucessfully)
Then flash any ROM, probably a stock one. Make sure the MD5 is good. Tell us your exact process for Odin-ing something.
Sent from my SCH-I510 using xda premium
This is what I have been doing the whole time, same result.
I know my process for ODIN'ing to be correct, battery in, SD card out, PDA checked only.
Its something other than that, I've flashed return to stock many times in ODIN before...
Is there something else I can do besides simply ODIN'ing, as I've said, I've tried ODIN and PST Lite, both failing at movinand.bin
When flashing straight to for example Tweaked, it works fine, as there is no movinand.bin
At this point, it does not even show the samsung logo anymore, the screen just quickly flashes for a moment and then turns off. Download Mode is still working though. Recovery does not boot either.
Correction, CWM does boot, but none of the partitions are mountable.
Umm, The same exact thing happen to me couple of weeks ago, I got tons of error about mounting. I know I am not helping, but I gonna say my case anyway. I tried PIT (repartition) several times, didn't work! It was random! it worked one time, and I was able to flash the pit, but when I tried to flash the EP4D didn't work! I only was able to get to the home 2 times and got tons of force-closing warnings. I have insurance, so I got a replacement. I hope you are covered as well! Just wanted to share
A fail at movinand indicates a corruption at a hardware level. I've actually pulled mine out of death (had the same issue once upon a time) just by spamming PST over and over again but I seem to be the only one who had ever succeeded in that. You're probably going to have to end up getting a new device but hey, they won't be able to tell you rooted.

At this point it won't even matter. My phone broke like this and I got it switched in on the last day of warranty (luckily), and that was in August.
one last check:
have you tried using a different USB cord/USB port/different computer? I, along with many others, have experienced issues when flashing via odin with a bad cord/port (even though it had worked before). when I switched cords, it worked. but this mostly happens when the computer/ODIN fails to recognize the phone.
also, I did not remove the SD card in any of my flashings. I think once, I did remove the battery just to get the phone into download mode.
oh, and another option could be the kernel/partition/boot animation you were last on. I would recommend to try to make sure you are on RFS with stock FP5 before flashing anything.
but i suspect kvswim is probably right.
hope this helps.
ok, thanks for the help guys. I'm quite sure I dont even have a warranty on my phone, so that sucks. Might try to go into Verizon and see what happens anyway.
Do you think its worth sending it to MobileTechVideos for them to debrick, or is this outside of what they do, since it still can go into Download mode...

Problem (well kind of) after restoring a back up

Here's what's going on. I flashed an aosp rom(all I ever use). Didn't like it and restored a previous rom I had backed up(I do this all the time). After the restore was done or so i thought the phone just rebooted and wouldn't load anything past the Samsung screen just black and then reboot followed by the same thing. I pulled the battery loaded up recovery manually and tried another backup I had and same thing. I finally ended up going back into recovery manually again and loaded up a rom. It worked but now the phone won't wipe I forget what it says when I try to wipe. Iv since loaded up several roms with the same wipe errors and all seems good. Just weird. I'm using twrp btw. Any ideas on what happened?

Well, if you're GS3 is running then I wouldn't worry too much. However it couldn't hurt to make a nandroid, restore back to stock, and redo the STOCK>root>unlock>flash recovery>flash rom process. You may have messed something up along the way. Either way, happy flashing. PS: you should try out paranoidkangdroid if you love the AOSP experience. CM base with a ton of tweakability.
Anybody else ever experience anything like this?

A thought.... I flashed a wrong kernel once, I would see the boot animation, then black screen. Maybe you have a wrong kernel?
