[Q] Can't escape from boot loops.. please help..

Hi all,
I have an LT15i. Has an unlocked bootloader. No problems using fastboot or flashtool. I have the latest DoomKernel installed. The current setup is attached.
I tried 3 different GB roms. These are:
-TeamXperia SE Tweaked
-T.e.a.m Stock Rom
-Arconium 8.2
No problems installing the zip files thru CWM but then I get boot loops.. EACH TIME!
I wipe all cache.. I do factory resets.. Try again.. No go.. still get loops..
Could someone please tell me if I am missing something? Thank you.
PS: And do you happen to know why I have both 5.0.2.7 and 5.0.2.8 cwm on my phone? If I press down on the volume locker it loads 5.0.2.8 and up loads 5.0.2.7.. is this normal behavior? One is touchscreen enabled, the other is not..

Did you also format system?

You must check to have the proper kernel and ROM. GB Kernel will not work with ICS ROM and vice-versa.

There is no format option in CWM.. Which one are you talking about?

Yes there is on mounts!
Edit: but like okty2k said check if you have the right ROM and kernel!

Oh yes, sure.. I'll try formatting and let you know..
and about DoomKernel V22 and .62 GB rom.. wouldn't that work? If it won't then which kernel version should I use that has cwm?

It should. Just to double check, try another kernel.

p.s. why you don't move to ICS?

I was running ICS Alpha.. The phone lagged, touchscreen would stop working from time to time, force closes.. Got sick of it.. I just wanted my old system back..
Though I have not yet tried the official release of ICS.. Do you have an Arc running ICS? Are you happy with it, I mean the OS?

Dude 4.0.4 kicks ass!
Sent from my LT18i using XDA

Well that's good to know that it does
I guess DoomKernel V22 is intended for ICS because I did like you said and formatted system too this time. Still no joy..
Since none of the three GB roms are working, it must be a kernel-rom incompatibility thing..
I'll download ICS and give it a go.. Thanks for the help mates.. I'll let you know about the result

Cool! Let us know your feedback about 4.0.4!

I just installed JJ's Hybrid ROM. Been using it for the past 20 minutes..
My phone has never been snappier! I love how you can browse apps and widgets with previews.. Loving it already!
Let's see it after I install Launcher Pro though

I have a similar problem but I cannot accese to the recovery mode, my arc just loops and loops... can u tell me how to access recovery mode??
I already tried Power +back and many other combinatios and no response....

If you have a kernel with cwm then you should be pressing volume down button a couple of times while booting..

i have the ClockworkMod Recovery 5.0.2.6, while booting I press volume down and doesnt enter...
any other suggestion??

Vol up or down works for me. I would flash the cwm kernel again if I were in your shoes..

No good... volume buttons are useless... dunno the reason...
How can i flash de kernel, without being able to access recovery mode??
thxs for the replys

[Q] Soft bricked my phone

So this is kind of a unique issue i'm having. I have the I-747 on AT&T and flashed AOKP rom (it was taking too long to get JB). It worked for about 3 days and then got stuck in the android boot screen (used the rom feature to get rid of the pink unicorns). after that, I booted into recovery and reset my phone, and it worked again for a few more days, then it wouldnt boot again (I dont believe I changed any settings between the boots). After this time, it wouldnt let me boot into recovery and would only boot to the android start screen and stop. I used odin to flash the stock rom, which only took me to the 2nd samsung boot screen and stopped (after the AT&T splash shows up). I looked online and saw someone say try CF-root using odin, tried that and it didnt help. Then tried using a custom kernel siyah s3, and now it will only show the initial samsung splash screen before turning off again. Any suggestions here? I figured I'd stop researching since i dont want to really mess up my phone worse than it already is

Your main issue now is that you flashed siyah. We don't have one. If you can get to download mode, you will want to flash back to stock.

Thanks guys! So I used odin to flash the stock boot loader and stock rom, but it is still hanging up on the 2nd samsung screen like it initially did (the one after the AT&T boot animation). Any other ideas on what could be the cause?

How long is the hang? Sure is just not the 1st initial boot of the new rom?

The first boot can take as long as 5 minutes sometimes. So, if you haven't waited that long, then try out some patience. Otherwise, try booting into recovery (stock now) and factory reset.

bump!
I have this same issue. I have restored to stock rom and it does the Samsung boot, then AT&T, then it goes to Samsung pulsating with a blue pulsating LED.
I have left it in that mode for at least 15 minutes and it never boots.
I can still get into download mode.
Thanks in advance for any help!

Has anyone tried booting into recovery after flashing the stock ROM and wiping caches then rebooting?

I let it run for 2 hours (left the house came back and i was still on. And phone wont boot into recovery at all ( i tried many times, but it just boots normally and skips recovery until it gets to the 2nd samsung screen, then stops there).
I dont know if this is relevant, but while the phone is off and plugged in, i can still see the battery meter and the Green LED (so i'm guessing it's still working, it just wont boot)

I went into recovery many times before, I'm definitely hitting the buttons right but it still wont go into recovery, it just tries booting like normal. I can go into download mode easily, but that's it.
jbizz, did you start getting this error after flashing AOKP rom also? trying to figure out what could have caused the issue in the first place

I'm not really skilled on these things, but I once had a similar issue with my phone not booting and had to end up using Kies to emergency restore it. Odin wouldn't recognize my phone but kies would.
Although I think my issue with odin may be stemming from my computers usb ports...

I actually flashed a bad kernel and the phone wouldn't boot after that.
What is the proper way to boot into Stock Recovery?
Sent from my SAMSUNG-SGH-I777 using xda premium

Fixed it! What I did was go into Kies software and did a firmware upgrade instead of trying to flash from odin, then put it in download mode instead of recovery, but it still worked. Thanks for all the help, guys! guess it's time to move to a CM based rom?

Sure, I'm doing this largely from memory since I mostly figured it out by throwing stuff at the wall to see what sticks.
Open Kies->tools->firmware upgrade and initialization->enter model name then serial number (they're behind the battery) -> put the phone in download mode and plug it in. it should take care of the rest.
Fair warning, this will fully wipe your phone, i lost all my pics (thank you google+'s instant upload or i'd be PISSED) and titanium backup (there goes my 3 stars on every level in angry birds and great scores in temple run), but at least you get a phone that can function as more than a paper weight, right?

Only have download?

Hey, I rooted my GS3 and installed cm10, but it was very buggy so I tried to reflash stock. As of right now I can get into download mode and that's it. I tried reflashing stock but idk if I'm doing it right.

How are you doing it?

Thanks for the quick reply! Through Odin, I've managed to hear the start tmobile sound but the screen stays black.

I'm not really sure what the problem is, but did you use the correct stock rom for Tmobile? And you did it through the download mode by holding down button, home, and power right? Just making sure it wasn't clockwork or twrp.

I am unable to access recovery.
If I could get to CWR I'd be okay.

I flashed an insecure boot and now it just stays at the glowing samsung logo.

That's one of the reasons flashing back to stock can be hard. Try flashing the stock image that is injected with a custom recovery (cwm I believe) found in the developers section.
Wiping during this operation is crucial so as not to get stuck in a boot loop

Barret,
Be patient. Wait for 3-5 minutes after boot.
Once it's done, see this --> http://forum.xda-developers.com/showthread.php?t=1999922

Thanks everyone, here's how I fixed it:
I flashed the stock rom without auto reboot and then pulled the battery.
Then, I flashed CWR without auto reboot and pulled the battery again.
After that, I could get into CWR so I flashed cm10 and a different google apps package than last time.
I don't have any cm10 bugs now. It would crash acore alot and stock apps like messaging wouldn't work.
Thanks for the help everyone, I'm set now.

Yeah, that's the one I used. Dialer, contacts, and messages would crash immediately and process.acore would stop responding constantly.
I tried Defy GAPPS instead and that worked.

[Q] Did I soft-brick my GSIII?

I've searched relentlessly for a solution to this, but I haven't come up with anything, so it's time to ask for help.
I just used mskip's Galaxy S3 QCOM Toolkit v2.3 (http://forum.xda-developers.com/showthread.php?t=1746682) to flash CWM and root my GSIII. The recovery flashed successfully, using "recovery-cwm-lte-sgs3-v5.tar" included with the toolkit.
CWM recovery works. However, when I tried to boot the phone, I got the first Samsung splash screen, then the screen turned black, a second later the boot tune played (with no splash screen showing), and then... nothing. The blue notification light blinks infinitely, and the phone is unresponsive except for holding the power button down for 10 seconds, which restarts it, and the same thing happens again.
I can boot into CWM recovery, as well as download mode. I tried wiping the cache and doing a factory reset, which changed nothing. However, when I tried to flash a stock ROM (again using the toolkit), I got an "unsupport dev_type" error. I presume that USB debugging has been defaulted to disabled now from this, but maybe I'm wrong. In any case, I'm not sure where to go from here. I don't want to claim that I've bricked it yet, when I have both recovery and download, but I don't know what to do now.
Help?
EDIT: I'm sorry, I forgot basic information : I'm using a SGH-T999 (T-Mobile GSIII).

I would defiantly boot in to cwr and do a clean install on a diferent rom. Not a back up u made with cwr but a .zip rom... n u sgould b ok.. I would try jb smooth

See if you can flash CM10, if you don't have to have stock.

Looks like the toolkit installed an older version of CWM. I flashed 6.0.1.2 via ODIN (http://forum.xda-developers.com/showthread.php?p=30806933) and then flashed CyanogenMod 10.0.0. Works great.
Thanks so much!

I was originally on a CM rom but decided to give a stock based rom a try and it flashed and booted successfully. Now I want to go back to CM and flashed another CM rom but now it won't boot. It flashes the LG logo for a half a second and then just hangs at a blank screen. Any ideas?

I encountered something like that a while ago. I solved it by shutting it down (hold power button for 20 or so seconds) then let it sit for about an hour.. It booted up after that. Hopefully it works!

Which AOSP-based ROM did you flash before you encountered the problem?
Did you wipe everything before flashing?
Did you flash anything in addition to the new ROM?
Are you still able to get into TWRP Recovery?

Yes, I'm still able to get into twrp but restoring now fails.I went from BeanStalk to Vectus Slim to NexOGen to SuperNexus (never booted), now I can't flash any stock or cm based rom without it hanging. I always wipe system, cache, dalvik, and data before flashing into another rom. I only flash the rom and gapps.

do you guys think if formatting the card and sideloading a rom might help?

I don't believe I have. I never had any issues until now.

I found this thread which seems similar to the problems I'm having. It seems like formatting data could fix the problem. If not, i'll try LGPNST and flashing teenybins next.
Thread: http://forum.xda-developers.com/showthread.php?t=2342985&page=2

I believe flashing a teenybin was recommended for CM so occurances like the LG logo to black screen would not occur. This happened to me, so I know by experience. A lot of people dont do it because it seemed to complicated and flashed CM and nothing happened, most likely it will happen to them sooner or later.
Good luck with the teenybin, I'm pretty sure that will solve your problem, as that solved my LG logo to black screen problem months ago

Did not know this, thank you very much. Formatting the data and flashing a new rom via adb worked by the way. As you suggested, I just flashed the original teenybin with LGNPST and everything went smoothly. Hopefully, I don't have to run into the logo black screen issue again. Thanks!
