[Q]Soft-bricked USCC Mega 6.3 LTE - Samsung Galaxy Mega

So after reading up in the forum a bit, I learned that I'm not supposed to try flash the ROM with odin before rooting.
But it happened. Now the phone won't boot and gets stuck at "SAMSUNG" screen.
Trying to go to recovery mode will only reboot the phone.
Before I lose the access to the recovery mode, I did the factory reset thing (wiping data and partition)
What should I do to unbrick it? (The model is SCH-R960U)

Really? I don't think that the case, you don't need to be rooted to flash the ROM via Odin.

Did you try to flash a firmware or a custom ROM? Firmware can be flashed in ODIN without root. Custom ROMS can only be flashed when phone is rooted and should be flashed via a custom recovery (cwm or twrp).
I have the MetroPCS version Mega so I'm not sure if your phone has firmware, root, or custom recoveries available.You have to search the forums to find out.

[Q] How to fix CWM loop after installing Mobile Odin?

I made a mistake of installing Mobile Odin Pro on my friends Galaxy Note I717 (Bell) and now I can't boot into OS anymore. When rebooting system it just keeps going to CWM. We have tried full wipe it is still stuck on CWM.
How do I fix this?
Thanks in advance.

Installing Mobile Odin on the i717 is one thing, flashing stuff through it is another, Mobile Odin does not support i717 yet as you may have realized in the process. Did you flash anything using Mobile Odin on the i717?
Was CWM installed prior to using Mobile Odin?
I would download ODIN on your computer, find a bell stock image, and using ODIN on your COMPUTER to reflash it back to stock, and hopefully that will bring you back. OR if you are able to get into CWM, from there flash a i717 version of CWM (or TWRP which is found in the i717 dev sub forum) and reboot into that recovery, have a compatible ROM on your SD card and then flash that, as well as a compatible kernel if the ROM doesn't include one.
There was nothing flashed through Mobile Odin. After that we installed Quickboot Reboot app. Thats when the CWM bootloop happened. So my friend flashed pda-odin-bell-stock.zip from http://forum.xda-developers.com/showthread.php?t=1599127
He is stuck on Samsung logo would not go to recovery.
Does he need to flash the kernel separately (after or before) and which one?
So using the key combo power plus both volume key let vibrate then release the power key not working? If u can get into recovery then u do a full wipe and you should then reboot into stock install.

Galaxy s3 GT bricked?

First off I know I shouldn't have done this before I was sure what I was doing, but I have done it.
I have used chainfires mobile odin pro to flash siyah's latest kernel to my rooted s3. i put the .tar on external sd. Opened mobile odin, opened file, and pressed flash. It said it's dangerous, I pressed continue and the phone immediatly rebooted, and is now stuck on boot loop.
I had never updated the phone from when it first came out, I just rooted and kept stock rom.
Any help much appreciated,
Thanks in advance.
Try to boot into download mode if this works you can flash a stock or custom Rom and kernel through Odin ans it should fix your problem.
Or try to boot into recovery and flash a custom Rom, either way should fix the bootloop.

As a precaution I'm going to ask if you have the American or international model.

Currently in download mode, going to try to install the latest kernel. Do you think that should work, or should I install custom rom?

I would say you just need to flash the kernel if that's all you changed, the Rom should be fine.

Did you choose kernel>open file>flash?

[Q] Can't re-root after flashing stock ROM [XXEMC2]

Hello all,
About a week ago I ran into a problem with my phone which I thought was a software, which actually turned out to be a hardware issue with my sim card. Cutting a long story short, I flashed the official stock rom with Odin V1.85, and it passed and everything was back to default factory settings.
Having now got my issue fixed, I wanted to re-root my phone, in order to go back to the old ROM I was using [UltimaROM v12]. However after flashing various versions of CWM I cannot get my phone to root. I'm no stranger using Odin, I can usually install a new version of CWM in 30 seconds, but my phone is persistent on not rooting. I can't work out if maybe I've done something wrong, but it doesn't seem to be working.
I've tried running as Admin on W7, but it doesn't make a difference, I'd appreciate if one of you guys could help, as I used the search bar before, but it seems no-one has had this problem before.
Modem: XXEMC2
Kernel: Stock
ROM: Stock
Use TWRP or Philz recovery .

I've tried those too, they don't work either.

What exactly is the problem? Phone not recognised? Flash failing? If so at what point? More details please

The problem is the recoveries will look as if they've installed fine through Odin getting a "passed" flag, but when I go to recovery it's still the default Android recovery. Therefore no root.
What root method are you using?
Chainfire one I believe. You basically install CWM recovery, then install SuperSU from .zip in CWM.
So you have rooted but can't install recovery?
Just flash one with mobile Odin,
Nope, no root yet, because I can't flash SuperSU.zip 'cause I'm still on the default recovery.
Just use the old cf root then update the recovery or use framaroot and flash recovery with mobile Odin
cf-root roots the phone as well as changes the stock recovery to cwm recovery! is this the exact one you flashed? http://forum.xda-developers.com/showthread.php?t=1695238

I think he is using cf auto root

[Q] Stock recovery in CWM flashable form - anyone have a link to SDS safe version?

Decided to switch from custom recovery method to using mobile Odin for flashing, so the bootloader flash counter can be reset - kernel is also stock.
I can find threads for modems, bootloaders and kernels but the only links to stock recovery I could find was sticky threads and over a year old, so not SDS safe.
Does anyone have a recent .zip CWM flashable version please? I'm keeping the custom ROM I've already got, so don't really want to flash fully stock just to get the recovery.
Thanks.
Also, reading through those stickies some of the advice and files they link to are well out of date - noobs could end up flashing ICS if they follow some of them.
There's a safe stock recovery in the cf auto root tar. Maybe that'll flash via mobile odin?
Or take an existing recovery cwm.zip (example philz recovery) and put the recovery image from cf auto root or any official rom in it instead

Thanks, didn't think of that - it flashed in mobile odin and installed recovery perfectly, but removed root. Had to flash again on the pc to regain root, triangled away and updated the bootloader and I'm now at peace with my warranty information.
System is still modified, as it's rooted but I can live with that.

Yeah I have modified status only. Since I have an ICS bootloader (I don't use download mode) I don't have flash counter increased.

Cant flash any recovery image :(

Hey Guys,
So I was running the google experience rom v3 and I decided to head on over to another rom but forgot to wipe before hand and my phone got a little wonky. I eventually ended up doing a complete Odin factory flash which brought me right back to VRUAMDK, when I went to install the OTA update to VRUAME7 my phone would reboot but would not apply and changes and I would get a notification telling me I cant update. I used an Odin flash to the VRUAME7 stock rom and that worked but for some reason I cant flash any sort of recovery now. Booting into recovery just brings me to download mode. I've tried flashing a recovery with Odin with failures on the write. Did I seriously F&#$ up my Nand? I just want to be able to run a recovery and have my GE S4 back Any help would be majorly appreciated.

The VRUAME7 firmware patched the Loki exploit and therefore you can not install a custom recovery. Right now all you can do is root the device also there is no way to go back to the VRUAMDK firmware.

Wow, am I really that oblivious? apparently.. any reason why this might not work on VRUAMDK either? pretty sure I tried flashing through goomanager on that and ran into the same issue..
