CM12 Rom For Galaxy Mega I527M?

Is there a rCM12 rom out for the Galaxy Mega I527M yet? And if so where is it? And if not, is someone making one?:confused:
[Samsung Galaxy Mega] starmaster10:
Check this post as this has the TWRP recovery link http://xdaforums.com/showpost.php?p=47331804&postcount=11 for your phone and choose the .tar file as it is easier to work with and this file can be flashed with odin and it will root your phone..NOTE..once down flashing the TWRP recovery reboot into it right away again otherwise TWRP may not work correctly..this just has to be done once when you first flash TWRP recovery. :good:

Wouldn't go into Download Mode

Hi Monkeywoman, I have downloaded the file and when I got to the part where it asked me to put the device into Download Mode it wouldn't boot into this mode. It didn't do anything actually. Didn't think Rogers locked their boot Download modes? Or I'm I doing something wrong? (Volume down+Home+Power)

Merry Christmas
[Samsung Galaxy Mega] d4ndr0id:
It's tricky with the mega. The way I do it is boot the phone and once the mega slash screen shows press and hold power+ volume down + home.

If you hold all 3 and try to get into download mode it'll usually just boot loop

No SIM card error

I have a sgh-i527m (Bell) which got unlocked. I tried a few custom roms but went back to this stock rom since I wanted full functionability.

Periodically, I would get the "no sim card" error. A simple reboot or re-insertion of the sim card usually fixed this issue but earlier today, It just clunked randomly and no matter what I tried, I could not get my sim to work (Fido). I even went to Fido and got a new SIM, since my sim was so old it wasn't even the LTE sim. And still no luck.

I even tried using the scotch tape Nexus fix, still nothing.

I am now re-flashing the stock rom via odin but I'm just asking if anyone has had a similar issue and could shed some light?

Also, my friend's SIM works fine, which is Rogers but my Fido sim won't work. Ironic, because Fido uses the Rogers network..it makes no sense.
[Samsung Galaxy Mega] starmaster10:
I would get a new sim card then..as maybe the one you have now is not working correctly at times. :D

The 9205 cm based Roms in the original android development section work pretty good. Check the first post of the threads and ask to make sure the Rom I'd compatible. Myself in rocking a beanstalk custom Rom and am pretty happy.

[Samsung Galaxy Mega] starmaster10:
It should flash the stock rom and boot no problem into recovery and the rom as that is weird it did not work..what I would try then is try the .pit file that is in my first post in this thread and put it in the pit window of odin and flash it as ir will re-partition your phone..make sure re-partition is checked as it might be already when you add the .pit file and then re-flash the stock rom and see how it works then as it should work with the stock rom..and the stock rom has to be flashed with odin and rom file will have to be unpacked first to get the .tar.md5 or .tar file..let me know how it goes.

Then you can re-flash the recovery but if you use the kitkat supported recoveries as you should and after flashing you must reboot into tbe recovery right away again as this has to be done in order for the new recovery to work properly and from the device installing the stock recovery back in again..:)

Cheers Starmaster10; thanks for the reply! Unfortunately using the pit from the first post gave me a Secure Check Fail.

Any other suggestions? Still no boot. :crying:
[Samsung Galaxy Mega] starmaster10:
But before you flash if you can get into the recovery stock or custom, while phone is powered off just hold the power button and vol-up button until the mega screen appears and release and it should go into the recovery mode and if it does you want to do a factory reset as this will clear old stuff out and put it back to factory status and then re-flash the stock rom.

To get into the download mode when phone is powered off just hold the power button and vol-down button until the warning screen appears and release and then push the vol-up button to get to the download mode, now on the rogers phone this might be a blank screen but open odin and connect the phone to the pc and see if the first ID:COM window lights up, then you are good to go, now just follow the info below in this post.

That is weird then as i flashed the stock rogers rom on my sasktel phone and works great, did you unpack the rogers rom from the zip file as you need the tar file inside to flash via odin, the file should be I527MVLUAMH1_I527MOYAAMH1_I527MVLUAMH1_HOME.tar and when you start odin (make sure your phone is in the download mode first check info above) and make sure only Auto Reboot and F. Reset Time is checked and all the other boxes do not need to be checked, now click on the PDA window and find the rom file for rogers which will be that tar file above in this post and click on the file in that window and then click on the open button and give it time to load in the PDA window as it will take a while to load it.

Then once the tar file is loaded then you can hit the start button and wait for it to flash the stock rom and once done and when the phone reboots you can then unplug it from your pc, the phone will go into a recovery mode and update some stuff and will automatically reboot and the mega screen will appear and when it gets to the samsung screen after the swirl you have to be patience as once you flash any new rom custom or stock it will take at least 2 to 3 mins or more to get going as it takes time to get the rom ready on your phone, i would start with the stock rogers rom first to get you back to the stock rom.

See if this stuff above will work as it should by rights. :good:

[Samsung Galaxy Mega] starmaster10:
I have never heard of that before as it sounds like a resolution error as the mega only has 1280x720 resolution, can you get into the download mode (as without download mode it cannot be flashed the normal way) and what exactly did you flash on this phone when you first started and which files did you use as you have to use a recovery which has the melius codename as there is a crater one also which cannot be used on the mega 6.3, but if you can remember which files you used to flash would give me a better idea on maybe what to do. :)
[Samsung Galaxy Mega] iamthewookie:
Alas...I kinda forgot which caused the bad flash. I have tried so many failed flash attempts to revive my mega.

I am able to access download mode now....just not recovery.

I appreciate your help.

[Samsung Galaxy Mega] starmaster10:
Flashing a stock rom should never do this to a phone, did you do any other kind of flashing to your phone as it sounds like a resolution error, as i can flash any of the Canadian roms on my i527m without any problems and everything works, this is really weird why this is happening..only thing is flashing a wrong recovery might do this or maybe an app which most likely not an app. :confused:

Forgot to ask is your phone through rogers or another carrier. :)
[Samsung Galaxy Mega] SaHiLzZ:
I suspect there has been an update pushed out to the phone which is bricking the phone ala Knox downgrade issue, and can ONLY be fixed with the new full TAR file.

Anyone can tell if there has been a new 4.2.2 update after December pushed out to Mega?
[Samsung Galaxy Mega] magicninja:
It is trhrough Rogers and yes it came from an update............still no luck trying to find firmware that works but I'm looking
[Samsung Galaxy Mega] starmaster10:
I suspect the knox security also with an update and sorry to hear it kinda put your phone in this situation, i have not updated my phone yet and this is most likely why i have not had this problem at all, i cannot even get my phone back to official status as everything i have tried the stock rom flashing etc and it always just says custom status in the odin mode (download mode), even when trying to check for an update it says cannot be updated due to this device has custom rom installed which is a good thing i guess, at least the update cannot be done.

Hope you get your phone back up and running normal again and i will check around also about this as it could happen to me also down the road. ;)

Recovery? Download mode?

What can you access and what type are they stock or custom?

I was running stock on that one and all I can do is go into download mode

You didn't try using kies on the pc to get it back yet have you...unless kies will not work on it, but worth a shot, as i do not see any kmox enable stock roms for the Canadian version of the mega..okay i see you tried kies already in another thread..i will keep looking. :fingers-crossed:

Check each and every md5 first?

Try flashing a custom recovery and try to boot into that?

I am going to see if i can make a debrick.img file for the i527m and this might help, but i cannot find any info on how to make as they say you can make it from a .pit file but they do not tell you how..will keep searching and see if i can make one up for you, and if i can figure out when they say can be made by security..what is this security a program.?. :good:
[Samsung Galaxy Mega] starmaster10:
Debrick.img file is now available for the i527m mega in my first post in this thread. :D
[Samsung Galaxy Mega] magicninja:
What if we can't get to recovery.... Just download mode
[Samsung Galaxy Mega] starmaster10:
Well i did make a tar file of the i527m debrick.img file also which could be flashed with odin..but i do not know if it will work and how it will turn out in the end after flashing, if you like i can put the tar version in my first post for download, but i cannot be held responsible if it doesn't work right, but if you are willing to try it and if it works it would be awesome then. :)

The debrick.img is not for flashing anyways as a tar file is required for that and might not work that way, but you take the debrick.img file and use Win32DiskImager program on your pc to put it on a micro sdcard that you have to connect to your pc with an sdcard adapter and then once the image is on that micro sdcard you take your sim card out of your phone and put in the sdcard and battery back in and reboot phone and see if it will correct the problem. :good:

The link for i527m debrick tar file has been removed as it was not working when flashed with odin. :)

Desperately Looking For Help

Hey, everyone. So I am currently experiencing this same problem with my Mega with Bell. Has anybody found a solution? The only thing I can boot into on the device is download mode.

Any help would be tremendously appreciated.

Thanks,

-GB
[Samsung Galaxy Mega] Silesh.Nair:
Another option is to find someone with the same phone and ask him to download the update, not apply it ( untick auto update and check manually ). It is usually in the update.zip format and it is stored in the internal memory. If you can get this file, then, you'll be able to flash the kernel if its packaged as a boot.img.

They are in the /cache/fota_dn folder, I presume. You need to be rooted then.
[Samsung Galaxy Mega] starmaster10:
Well I would give it a whirl to just get the update fike..but I cannot get my i527m back to official status for some reason..I tried flashing stock rom, kernel..and even tried using kies and still status stays custom..even flashing stock recovery by itself and same thing.

Not sure why my i527m will not go back to official status. :eek:

So I installed the debrick.IMG with win disk imager. I put the SD card in my phone and rebooted but nothing happened. Am I doing this right?
[Samsung Galaxy Mega] starmaster10:
Hi..i believe that the debrick file cannot be used in certain conditions as it seems to be more used when check this thread Hard brick ( QHSUSB_DLOAD follow this guide ) as it doesnot seem to work in other situatutions that i know of, does not work on a knox triggered bootloader and i read online in many places once the know security is triggered and you can only get into the download mode..you are basically screwed and have to wait for a fix, but the new firmwares that have the knnx security in can be altered so you can still can have a rooted device, but this can only be done with the new firmware and if your device has the know security triggered this will not help it either, not sure if this knox security was your problem you are having.

But this debrick file only seems to work on what it says in that thread that i put a link to, as far as i know, but you did the procedure right, but your phone must have a different problem that this debrick file will not help. :)
[Samsung Galaxy Mega] fleagalbaum:
Yes I do have the knox security issue. Secure kernel fail etc... I might just get it fixed with a jtag if that is possible. Thanks for your work in trying to help us. I changed the boot.img from the stock Rom and replaced it with one from a cwm nandroid that I backed up before flashing. The new firmware Flashed fine and booted to the world screen but then it just hangs. I cannot get into recovery to wipe data to see if it will cure the stuck boot
[Samsung Galaxy Mega] starmaster10:
At this time hopefully a jtag fix will help, but i read on one site that a jtag will not correct it, now i don't know if i should believe that or not, i do have a riff box myself already..but i have to get the jtag ends yet as i was looking at a jtag kit already..hopefully doing a jtag will fix this or unless a fix comes out for it by flashing it only...but sorry to hear that this happened to you. :eek:
[Samsung Galaxy Mega] SaHiLzZ:
JTAG will NOT fix this issue as they will need the same boot file that you folks are missing. Unless someone reverse engineers it, but doubt it is on their radar if at all.
[Samsung Galaxy Mega] pcampbell1134:
Give up.. for now.

Just some more information for you guys with a Galaxy Mega Canadian SGH-I527M

If you have the problem of:

Download mode

KNOX KERNEL LOCK: 0xfffffffc

KNOX WARRANTY VOID: 0xfffffffc

When booting

Image size to large!! W:1080, H:1920

display image fail

SECURE FAIL: KERNEL

If you have this, then just give up. Details follow;

This is caused by Knox locking the kernel area. Restoring in Kies with "Firmware upgrade and initialization" will not work. Flashing stock rom will not work. Flashing just an extracted stock kernel will not work. Flashing a custom recovery, or stock recovery, will not work.

Reason it does not work is simple. Knox is not allowing anything to be written to the kernel/boot area as its failing a security signature check. Currently there is no kernel/boot/stock image (not even in Kies directly) that has a correct signature that Knox will allow to write to the boot/kernel area. This may change later when version 4.3 is officially released for the SGH-I527M.

Root cause of this: Samsung updated Knox without releasing a new Rom/Update/Carrier Update available to download.

Currently I have 2 Samsung Galaxy Mega that are completely worthless sitting here. I am not a happy Samsung customer. I can no longer recommend Samsung phones since this Knox crap has spread into the consumer markets, nor will I ever buy another Samsung product.

**EDIT**

Adding list of Knox status codes

Fixable with standard methods of restoring to stock:

0x0

0x1

Not fixable, if your phone showing one of the following status, sit back and wait:

0xfffffffc

0xfffffffd

0xfffffff1

0xfc1d3ffc (if see this, phone is dead, toss in garbage and buy something not Samsung)
[Samsung Galaxy Mega] fleagalbaum:
That is good information. Have you gotten a quote from Samsung for repair or is it beyond them.
[Samsung Galaxy Mega] shabbypenguin:
Let me get this straight, samsung pushed a knox enabled update for 4.2 for yall, some people that took the update tried to flash what is an older tar and thus have had issues?

should just be someone who took the update get root (using cwm/twrp) dump stock images and make it into an odin tar. anyone who has the new update and root wish to dump them lemme know :)
[Samsung Galaxy Mega] pcampbell1134:
...and its the song that never ends...

Still fighting with them. Hard to get anywhere with them as their "technicians" knowledge only goes as far as their screen will scroll down.

That is exactly what happened. Problem is there isn't a new stock firmware with the updates applied, there is still only the original 4.2.2 rom. Hence, bricked phones. Similar to HTC phones that you cannot get an updated firmware that is compatible with the OTA HBoot version. Videotron is the worst company for doing this, heads up to steer clear of their phones.

Soon as I can get a working Mega with the February update (one that is causing this problem), I plan to dump everything from the phone. Will share it after I have had some time to dissect it.
[Samsung Galaxy Mega] shabbypenguin:
alright well if someone with the newest update is willing to help me dump images ill make an odin tar to help fix everyone up :)

[Samsung Galaxy Mega] fleagalbaum:
Thanks for doing this. I am very grateful
[Samsung Galaxy Mega] starmaster10:
That would be awesome, but i do not have the update so i could not dump the image as i cannot even get my mega back to official status no matter what i have tried so far, but at least it keeps it from updating to that knox crap, but if i can get the update some how by getting the phone back to official status i could help in this matter. :)
[Samsung Galaxy Mega] shabbypenguin:
what all have you tried? has anyone even grabbed teh zip?
[Samsung Galaxy Mega] starmaster10:
Well i have completely wiped my internal card and tried stock rom as i am still on stock rom right now except for the rooting part, i have tried with superSU to unroot, and tried kingoroot and a no go, and even tried kies with stock rom and is a no go either..i even used the pc to wipe the whole internal storage and still shows custom status in the end. I am going to try minitool partition wizard 8 for the pc and see if i can wipe it all out, but besides that i am not sure how to get this mega unrooted. :silly:
[Samsung Galaxy Mega] shabbypenguin:
remove your sdcard, format internal storage and install the odin tar and you should be back to official status then. unrooting via supersu will still have already triggered teh samsung custom flag.
[Samsung Galaxy Mega] starmaster10:
Yes i was thinking of removing my external sd card and trying it as it might have something to do with not putting it back to official status, but never really thought it would have something to do with it..will give that a go then..thanks. :good:
[Samsung Galaxy Mega] shabbypenguin:
normally id say it wouldnt, but im still new to knox overall and idk if they scan looking for directories etc. i do know you have to odin flash in order to get back, tahts how it was back on the s3 long before knox.
[Samsung Galaxy Mega] starmaster10:
Okay tried that and even with the stock recovery i wiped everything and it still has custom status, i will get to the download screen and type everything it says. :confused:
[Samsung Galaxy Mega] shabbypenguin:
you flashed a fully stock odin tar, and did a factory reset and it still claims custom? which tar did you use?
