Mega...semi-bricked?? - Samsung Galaxy Mega

So I have a Sprint Galaxy Mega and it seems as though it may be semi-bricked. It will not boot past the GALAXY MEGA logo. It will just continuously power cycle to and from that logo. If I attempt to put it in recovery, it will say "RECOVERY BOOTING" in blue letters as usual, then power cycle right back to the GALAXY MEGA screen. It will boot into Odin mode and accept Odin files, but after attempting do do a typical "stock Odin" scenario, nothing has changed. I looked around for the Pit but cannot seem to find it. Does anyone has a reliable link to the latest Odin stock restore and the PIT file that matches it?

Maybe an error with your system data. So you can't reboot into recovery ? If you can try to wipe data and cache and reboot.
It may be an abnormal re-partition when flashing stock rock, and then I can't help you (have the i9205 international model). Some members of this section have the Sprint version, try to send them a PM if nobody can help you

Nope, no recovery. I was considering flashing a custom recovery to it to see what it does but I don't wanna kill the phone any more than it already is...

Yes I understand. But flashing custom recovery can solve your problem, only if you can boot on it. I think it can't make more damages to your phone, he just always stuck on boot phase like a brick, but if you don't want to try, wait for a developer making you a PIT file. More safe, the Galaxy Mega have a too poor development support for risk anything...

Well I went ahead and flashed TWRP to it. It will boot into TWRP just fine. Tried flashing the stock L900 ROM zip and it still won't boot.

Well I installed a custom ROM, SlimKat, and the phone boots. If I install the stock ROM located in the following link, OP's signature, the phone goes right back to bootlooping. ???
I need either the stock ROM or a ROM with dialer codes because this phone will be flashed to a regional carrier.

what recovry version you use bro. maybe recovery problem. try use your custom rom to flash another recovery from philz. the latest one. some time recovery dont work properly to downgrade from 4.4.2 to stock 4.2.2.

Great, so with Philz Touch Recovery, I never had problems for downgrade and I do this often for testing roms. Now it should not bootloop if you reflash stock.

I am using "CWM-based recovery 6.0.4.7"
I will try Philz recovery

After trying Philz recovery to flash the stock file I found, it once again bootlooped. Is there another stock ROM floating around somewhere or possibly a custom ROM that has dialer codes such as ##3282# enabled?

No idea... But actually the most complete stock based custom rom is MegaFire I think. Flash V5 (not V5x !) it should be enabled.
I don't see what is the problem while flashing stock rom... Oh ! Maybe you haven't enabled USB Debugging, I forgot to do that one time and I had some issues, in case you try to flash a firmware where Knox or others features are on with a modem without these, may cause bootloop. I've searched for 2 days before solve that little problem...
Have you tried another firmware ? If you can flash custom rom, something went wrong before flash... Odin folder is complete ?

Strange...once again a boot loop after flashing the MegaFire ROM

I'm almost certain I need the PIT file. I cannot find it anywhere.

Well I got the phone to boot from that rooted stock ROM FINALLY. I don't remember for sure but I think what I did was first flash TWRP, then flashed boot.img.tar that I found somewhere, it was listed for the Sprint Mega. I then booted into TWRP and flashed the stock rooted ROM(zip) I mentioned before. It now boots perfectly and everything works except one tiny little detail. No WiFi, no cellular signal at all. Baseband version: unknown in About phone.Already tried flashing the Sprint stock modem from the same download link as the ROM and it didn't work.

I'm having the same problem too dude, I
I download n flash all.the firmware I could find online, since I have no idea what the country of origin is. But most of them work, but no WiFi, Bluetoothand the sim card slot don't read

Stock ROM doesnt work

Hi there.
I had a custom rom on my Galaxy S3, and I wanted to go back to stock rom. Before I had a custom rom, I checked my product code, just in case if I ever wanted to flash stock rom. So, I downloaded a stock rom from sammobile and flashed it with Odin. I had a successful flash, but when the phone rebooted, it stopped at the samsung logo and it's like that every time I turn on the phone.
I aslo tried to flash it with the same rom, but from a different site (androidfirmwares), but every time I treid to do that, Odin crashed ( Odin downloader has stopped working).
I can't even boot into CWR to flash any custom rom, cuz it's gone. There is only stock recovery.
Please help
Which Rom were you trying to flash when this happened, and give details of how you flashed please

if you are getting stuck on the boot screen after you flashed the stock rom this always works..go to recovery do a data reset and wipe cache.
this is really weird and a stupid thing I did when I was completely new to android..a little over a month ago.I got stuck on the boot screen and accidentally flash CF-Root instead of the stock firmware..when the phone rebooted it worked just fine.I dont think its supposed to work that way..:S

[Q] Galaxy S 2 Boot Error

Hi Everyone! just a rookie here in need of a bit of advice.
I'm a Galaxy S II I9100 owner and have my phone rooted and all setup with custom roms and been comfortable with flashing for some time now. My ROM of choice recently was Vanilla Rootbox and have to say the ROM has been fantastic with very few bugs to report. Last night i recieved the OTA update via Goo Manager for Vanilla Rootbox 3.4. I downloaded the full update over wifi and flashed with all wipes no worries. Next step was to flash the latest GAPPS and i figured there would be nothing wrong with flashing the GAPPS zip i had on my sd card that i had downloaded the last time i was notified of a GAPPS update via Goo manager as well. After flashing, wiping everything and rebooting again. My phone then booted up to a series of dialog boxes indicating that many google processes had stopped functioning. apps.google.com etc etc. A similar error has been reported in the Vanilla Rootbox thread by another user but i wasnt able to report this bug their either because my post count is too low to post in a development forum. So after seeing this error i rebooted into recovery to flash my last backup but CWM recovery came back with an error messaging stating it couldnt mount either ext or int sdcard. i did a factory reset which made no difference to the problem whatsoever. I then downloaded ODIN and the latest stock ICS Rom and flashed it via ODIN with no reported errors. My phone now boots through the optus boot animation and is stuck at the Galaxy S 2 screen with the flashing red and yellow animation over the S. If i turn off the phone with the power button, the phone turns off and immediately starts again and gets stuck at the flashing s screen. I've taken the battery sim and ext sd card out and put it all back in only for the problem to persist.
If anyone could help me there's a donation and my thanks in it!
Much appreciated
Nick
tried to re flash another stock ROM?
If so, tried factory reset the phone after the flash?
As long as you can get to DL mode, you are good to keep on flashing till you are up & running.
And then you got this
Remember to update your kies and make sure you close it all up before flashing with odin. If you are in 4.0.4 beware of the brick bug.

Kies has never been installed on this computer but i did use the usb drivers mentioned in the soft brick recovery guide you linked. I used some information from the guide to flash this stock rom but i couldnt flash or wipe the partition because im unsure where to get the .PIT file required? i cant get past the boot animation so no factory reset possible and yes i can still get into download mode!

wow wow, leave pit files alone for now, they are nasty.
What stock ROM did you flash? 4.0.4 or 4.0.3?
You can factory reset via recovery mode.
Try installing kies anyway, it can't never hurt. Just make sure all applications are closed before you re-flash.
here's jb leak, might help:

Bricked?? Stuck at samsung logo screen for 1 sec then reboots.

Okay, So the title pretty much says it all. I am stuck at the Samsung boot logo (not bootanimation) and it only shows for about 1 second then reboots and continues.
This started after I tried to flash a rom and it messed up and I tried to flash via odin. I was on MJ9 and and got a bootloop so I did the odin thing. I've used odin before but it is not working well for me now.
I am able to boot into download mode but TWRP no longer works. I was able to flash via odin and it says success but the phone does not reboot like it should.
I have purchased a galaxy nexus on the cheap to hold me over until the nexus 6 is out but if I can fix my note, I would like to.
I know there were other threads about this same issue but it seems that they are all on a different version of the note, or on a s3 or something. Not to mention, I don't see anything that I could try without asking for some help on here. Can someone maybe point me in the direction of the factory firmware (preferably a rootable or already rooted version) that I can flash that will play well with my note.
Thanks guys!!!

Before you tried to flash a custom ROM and things went wonky...were you on Verizon's factory stock 4.3 MJ9 firmware, or on Beanstown106’s modified 4.3 MJ9 with TWRP installed?
Does the phone still boot into stock recovery? If so, you may be able to fix the phone by doing a factory reset.

If you were on Verizon's factory stock 4.3 MJ9, then you won't be able to Odin flash back to 4.1.2 or any earlier Android version because the bootloader has been locked down tight on 4.3 (and 4.4.2) with no current do it yourself method to unlock for those newer versions. You would want to restore the phone back to factory stock 4.3 though, if that's what version you were on before your phone got messed up. You can root the phone on 4.3 with saferoot, then use safestrap recovery to flash some custom Touchwiz ROM's.
If you were on the 4.1.2 based bootloader, (but running Beanstown106’s MJ9 firmware and TWRP), then you would want to restore your phone back to factory stock 4.1.2 and then root and unlock the bootloader again with CASUAL. This would give you the most flexibility with flashing custom kernels, ROM's, etc...
Check out Section 1b in Droidstyle's restore guide at this link: http://forum.xda-developers.com/showthread.php?p=34891181. The guide has download links for the files you'll need to restore the phone back to the correct build version.

[Q] I am about to give up. There must be a solution but I cant find it

Hi everyone
My sister updated her MEGA OTA last month. She cant remember which version she was on. I am assuming it was 4.3. shes doesnt know much,
Her phone got stuck in bootloop.
Initially a got a hard time even getting into restore mode. however after a lot of goggling and trials and errors here is where i am today :
1- I can install TWRP and/or Philz recovery and boot into them.
2- I can enter download mode
3- I have tried installing many ROMS and different versions. I was only partially successful with 4.4 versions because I get a passed message in Odin however upon restart the phone enters boot loop again.
4- I have tried multiple wipe data/dalvik cache/cache and restoring factory settings but i still get the same results.
5- Only in Philz recovery i can mount the external SD card and copy zip files. I was able to root the phone that was (but im not sure if it still is). However all ROMs zip files I tried to install (both from PC and from extSD card) wouldnt open in recovery mode.
Because I get a passed message when I install a ROM from Odin , I dont know what the issue could be. But there is something wrong that happens as soon as this phone boots up.
I seriously do not know what to do anymore. I just need this phone to be working again. At this point I dont care about warranties/ROM versions/stock or custom...
Please help and sorry for my bad English
It sounds like you need to download the stock rom and flash it in Odin (you gotta put the phone in download mode to flash in Odin). The stock rom can be found on the sammobile website in the firmware section. That should get you back to square one (stock rom, stock recovery, no root). Then you start over from scratch.
Sent from my SGH-M819N using XDA Free mobile app
Thanks
I did and I still get the same problem.
In fact after installing stock rom, i could not enter "stock" so I installed philz recovery, logged in philz and wiped cache a couple of time, did a factory reset.
and yet when i restart , the phone is stuck in bootloop.
Maybe she has a Galaxy Mega with a repaired screen. Starting with 4.4 Samsung only supports a digitizer with Synaptics brand chip. It's a big mess and there are countless screens and digitizers made worthless. I think unofficial 4.4 by Cyanogen and others might work, but not official Samsung. With some Galaxy Megas you get a bootloop. With others it boots however the digitizer and touch functions no longer work. I don't know how to go back after you are on official 4.4 because last I saw, there was no root for it. If I'm wrong, someone else please clarify and continue to help.
IMHO only one way out from such situation is try to flash MegaFire MJ2 which is derived from stock 4.2. It's only one 4.2 ROM which can be safely flashed onto KK.

Gt-i9100 stuck on startup logo

Hello everyone,
I own a samsung galaxy s2 gt-i9100 I've been using it for a long time. A few days ago i installed cynogenmod 13 marshmallow on it but faced some severe issues like dialler problems,battery drain,google play services not working. So, i switched it back to my previous rom i.e. cm 12.1 lollipop but my old twrp recovery got replaced by cynogenmod default recovery. Now some people who may have used it know that its very basic and does not has backup,restore, has bugs,does not flashes some zips or files that i wanted so i tried to replace it with twrp/cwm through rashr,flashify,rom manager,etc. But none of it worked, whenever I'd boot after flashing the twrp/cwm recovery it'll go back to the default cynogenmod recovery. Now, me not knowing what im doing stupidly downloaded mobile odin lite app then i downloaded the cwm kernel recovery kitkat compatible and installed via mobile odin lite. After that it got screwed, it won't just startup it'll just start and go into recovery i mean continuously! It was annoying, then i read an article on a forum to download any cm nightly or stable mod and flash it but i did a little bit of tweak of removing the recovery boot img file with twrp to get preinstalled twrp recovery but i gotta admit it was the last mistake possible. Now i sit here, with a bricked phone in my hand which is looping continuously only on the samsung logo. If anyone out there can assist me correctly it'll be a life saver for me. Thanks for reading this and please reply with a solution asap. Please! Im in danger!
can you get into download mode?
if yes you can download a stock firmware and flash but you will have to hope it will work, otherwise you will get stuck on nand write start which means the nand is stuffed/corrupted and then basically only a motherboard replacement will do the job, or you can try using another computer, reinstall usb drivers..
can you get into recovery mode?
if you can, you can flash a rom
The 'nand stuffed' assumption is a last resort, tried everything and nothing works assumption. There is *plenty* to try before assuming that the nand is 'stuffed'......
It sounds like (from your description) that you may have rendered recovery useless and inaccessible.
I've a feeling what you need to do is to go into download mode and Odin flash a firmware.
Even if it doesn't boot, you should have a recovery that you can flash PhilZ recovery from and then use that to flash a custom rom. Initially, I'd stay away from the MM builds and instead flash something KK or LP based as they're less 'volatile' and have a higher degree of stability than the MM roms.
