I'd really like to know. I havent touch this phone at all, i mean im even scared to try to root that darn phone.

Can't wait to try it out

Hi Guys/Girls,

I'm pleased to report I have ability to repair these units at this time via JTAG. I have successfully repaired an I527M suffering from the described issues earlier on in this thread via several dump files graciously provided by a few users here. This repair is currently limited to JTAG only at this time. You see, Samsung has begun signing firmwares for their units post Galaxy S4 and a few units before that. This means that each firmware partition (not all of them but the primaries like boot.img, recovery.img, system.img, ETC) are signed directly from the OEM. Therefore even a direct dump like the ones provided will do no good when flashed with ODIN as they contain no such signature. The days of producing your own firmware are in the past unfortunately with no ability to sign the images produced (without the leak of the holy grail Samsung signing keys lol). However, using JTAG, we can byte for byte write this information to the eMMC chip to replicate a working unit's eMMC image. Basically I am flashing the phone with factory firmware via JTAG which in no way works with KNOX and is the ultimate authority on writing and reading information from a device. The process is 100% secure and no IMEI/EFS information is compromised during the process so your device remains original in every way. So, at this time, I believe it will be the only way to fully factory restore the SGH-I527M after a brick when on the NA3 update.

Remember, I'm not here to sell you on anything. I am here to help provide world's first and only solutions to difficult issues with the aid of help by other fine members of the community who help dump these files. If I had something to offer as a USB solution, I would provide that for the DIY community. I work with many MODS and have many elite developer's personal phone numbers to discuss various projects in which I do a lot of behind the scenes work for debugging and recovery on brick sensitive work. I'm really just one of you doing this full time as a career to support my family and I. Anyhow, if you are in need of professional repair, we offer this service below at the following link. I can also revive a fully hard bricked DEAD BOOT unit in case you did just that much damage:

@starmaster10 [MENTION=2614663]shabbypenguin[/MENTION] - Donations coming as promised for your support on getting me proper dumps. Without you guys, the community has nowhere to turn with a bricked NA3 I527M at this time!
[Samsung Galaxy Mega] shabbypenguin:
while im sure many wouldnt consider it ideal, a solution has been found so thats good. and 50 bucks is still far cheaper than going out and replacing the phone. i know here in the US sprint wants 150 for insurance claims on broken devices.

even though i dont own a i527m thanks for helping fix em up :)
[Samsung Galaxy Mega] starmaster10:
That is awesome. :D
[Samsung Galaxy Mega] starmaster10:
You are talking about the NA3 firmware with knox in it if i am correct and you can still install a custom recovery like CWM, TWRP, or Philz and add SU as that will stiil all work good, just do not change roms or the kernel itself otherwise it will lock the phone down as that will trigger the knox security and then show the Secure Kernel Fail line then as the Knox warranty can stay at 0x1 as that will stay like that and when you use a a custom recovery and you go into it you will see a yellow line that says "Set Warranty Bit: recovery" as that is part of the knox crap also..but it does not effect the recovery in any way of it's operation. :)
[Samsung Galaxy Mega] Patnad:
I wish there was a proper thread / a clear list of what can be flashed without problems on NA3.

Is it even safe to use something like Kingo or motochopper to try to root the phone?

I know i used to install TWRP from the play store and use the option of installing the recovery from Android itself but i think this is what screwed my phone last time...

Anyways would be good to make all of this clearer.. or at least a thread with tested/working method to root and install cwm or twrp with the right files for our phones.
[Samsung Galaxy Mega] fleagalbaum:
I fllashed the most recent Pit, tz and modem. It booted up after accessing recovery and doing a full wipe. I never had a recovery before to do this.

Thanks for all your help.

My knox warranty void is now 0x1 but it boots and works good so far.
[Samsung Galaxy Mega] starmaster10:
You can use any of the recoveries from [MENTION=4551757]Silesh.Nair[/MENTION] signature in his post here and just click on the mediafire link and once on the site select recoveries and choose which one you like to choose as they both work on NA3 with knox, and use the tar file as this way you can use odin to flash them..Link here to the Philz recovery you can use also and select the tar file, and use SU 1.93 zip file as it can flashed with any one of those recoveries.

You can install recoveries and root the phone with no problems at all..JUST do not flash a different kernel or install any custom rom and do not try to flash back to the original rom as it will then trigger the knox kernel lock and then you will be screwed, and you can even make a backup with the recovery and it will restore it with no problems..just stay away from flashing another kernel or custom or go back to original rom and you be safe..as i have been doing this all along so far with my i527m mega with the NA3 firmware with knox in it.

Below is the SuperUser v1.93 zip file you can use to flash in the recovery and works great. :good:
[Samsung Galaxy Mega] starmaster10:
That sounds awesome. :good:
[Samsung Galaxy Mega] plpconstructions:
way to fix it?

does someone can find a way to fix it?
[Samsung Galaxy Mega] starmaster10:
Check this post here and flash the modem tz file and add the pit file which is in that quote window there and flash them with odin at all the same time and that should get you back to were you were before..it will show 0x1 afterwards. .but at least you will be able to use the phone again. :)
[Samsung Galaxy Mega] plpconstructions:
I just have to put I527M-NA3-Modem-TZ.tar in PDA and i527m.pit in pit?

im gonna try and give you some news

thanks a lot
[Samsung Galaxy Mega] starmaster10:
Yep..and make sure re partition is checked which it should be when you add the pit file. :cool:
[Samsung Galaxy Mega] adulate:
Hi all. I have read every post in this thread and now I could use some advice.

I have a Canada rogers Samsung mega 6.3 sgh-i527m

I originally tried to root mine but the cwm recovery I used with odin caused my wifi to stop working and google play to stop working and would crash anytime I tried to install anything.

So I decided to flash my phone with the official firmware which bought up the error

image size too large!! w:1000, h:190

display image fail

secure fail: kennel

I can go into download mode but that is all.

So then I used my official firmware and what as posted on here (modem, tz and tar) and when I flashed it with odin my phone loaded and worked. except no wifi still! wifi just wont turn on,

So I turned my phone off and held power, home, volume up and tried formatting cache and formatting info.

Stil no wifi.

So I tried 3 more times just flashing back to the official rom and my phone tells me image file too large,

What can I try?

It seems maybe my radio file is corrupt? or the modem file isn't compatible? its just wifi that wont turn on, I can make calls and do everything else.

Please help. It all seemed to go wrong when i put the cwm phone recovery on my phone with odin. Is there a factory one i can reflash?

Turns out I should have steered clear of trying to root my month old phone with my lack of experience,

---------- Post added at 10:47 PM ---------- Previous post was at 09:57 PM ----------

So here is more of an update, hopefully it will help others and help figure out what is going wrong.

In odin I tried just flashing original firmware which gave me image size too large error.

Then I tried just flashing I527M-NA3-Modem-TZ.tar and i527m.pit and it said pit failed in odin. Then I tried pressing volume up, power, home and it wouldn't enter it

So then I tried flashing origional firmware I527M-NA3-Modem-TZ.tar and i527m.pit and it said pit failed as well. Then I tried pressing volume up, power, home and it wouldn't enter it.

Then I flashed origional firmware and just I527M-NA3-Modem-TZ.tar and it boots with no problems. Just wifi doesnt work and it takes about 5 minutes for the phobne to boot up. Then I tried pressing volume up, power, home and it entered it. It formatted the data but says error when I try to format the cache

Hopefully that info might help!
[Samsung Galaxy Mega] Nubsta:
Thank you!!!!!!!!!!!! it works!

k so i'm like pulling my hair out over this...

1. i wipe system efs and everything for fun (k lets be honest i'm a nub)...sitting here with a "no OS installed"

2. download the stock rom and after flash it with odin i get...image too large...kernel secure fail lol...FML!!!

3. download the modem in starmaster10 post and only flash that with odin...NOTHING ELSE!!===> image size error is gone and finally can go in recovery and do a factory wipe and boot normally. (it take long though at "Samsung Galaxy Mega" screen each time i restart the device but i can careless cuz atleast it works!!! lol

Sry for terrible grammar and spelling and the inability to type lol :D

update:

no wifi but is now able to ROOT with kingo
[Samsung Galaxy Mega] magicninja:
It works.....I too had the Knox lock after installing a new update and trying to install a new ROM and root. I followed the directions a few posts back and voila. I am now able to boot into recovery which I also installed through Odin and restore an old backup I had.
[Samsung Galaxy Mega] Nubsta:
and wifi works for you?

did u end up with working wifi?
[Samsung Galaxy Mega] magicninja:
Not sure..... Screen is cracked and I just wanted to fix rom so I was able to sell it. Tomorrow I am going to switch screens so that I can check it out.
[Samsung Galaxy Mega] Patnad:
I really don't get it I guess, I tried to flash both recoveries (CWM and TWRP) they do flash without a problem and the phone still work good

But they wont show when I reboot in recovery mode, its still the old recovery showing.

Any tips at this point?

---------- Post added at 08:29 PM ---------- Previous post was at 08:26 PM ----------

I tried with a different Odin and it worked! Thanks!
[Samsung Galaxy Mega] Patnad:
My Mega Rocks now !

Thanks guys, just want to let you know I've finally made it, I am running BeanStalk now and im super happy with it!

Finally, I am in love with that phone again, its good to be able to flash any rom you like on Android, you shouldnt be limited to the one from factory.

:good::good:
[Samsung Galaxy Mega] starmaster10:
Nice..and i guess you were not on the knox enabled rom as you have beanstalk installed which is a nice custom rom forsure..enjoy! :good:

Okay when you flash CWM or TWRP not sure on the Philz recovery but once you flash it you have to go into the recovery right away again when you boot your phone otherwise it will re-install the stock recovery..you only have to do this once then it will go into the custom recovery after that when you boot your phone. ;)
[Samsung Galaxy Mega] Patnad:
Is there a way to keep the Samsung apps once you use a custom rom, example if you back everything up with Titanium Backup, then restore it in BeanStalk, would that work?

I know ive been able to fool around and install Samsung App Market so I can get my Galaxy Gear working, but is there a simple way just to get everything working again, ex TouchWiz, SVoice, SMemo.. ect.
[Samsung Galaxy Mega] starmaster10:
Well touchwiz I am not sure as custom roms that is removed..unless there is a touchwiz launcher available at the play store..some samsung apps may work but I am not sure in which ones as I cannot install custom roms anymore for a while or longer as I have the knox enabled rom in my phone to help out the community in this knox lockdown stuff..you will just have to try apps out and see how they work..but make a backup first just in case things get screwy and at least you can go back to were you first started. :D
[Samsung Galaxy Mega] Reba 999:
Exact same problem

I too have the EXACT same phone and i have the same carrier which is rogers in canada and now my screen says the exact same thing as his is saying! im not sure if your problem was resolved but if so could you please tell me what you did to fix this or if anyone knows if they could please help! when im in download mode it says the following

PRODUCT NAME: SGH-1527M

CURRENT BINARY: CUSTOM

SYSTEM STATUS: CUSTOM

KNOX KERNEL LOCK: 0Xfffffffc

KNOX WARRANTY VOID: 0xffffffc

CSB-CONFIG-;LSB:0X30

BOOTLOADER AP SWREV:2

WRITE PROTECTION :ENABLE

and when its not in download mode the screen says exactly what yours says ? wtf: i have worked on phones and used odin alot and never had this happen..so any help would be so much appreciated!
[Samsung Galaxy Mega] Nubsta:
Read page 24 to 25 fix mine but still no wifi for me

---------- Post added at 07:19 AM ---------- Previous post was at 07:06 AM ----------

Beanstalk support mega? I tried to find it on the beanstalk thread but couldnt find one for the mega...oh and any idea why wifi wouldnt work after flashing modem file you posted?
[Samsung Galaxy Mega] starmaster10:
Okay with the beanstalk rom or other custom roms for most mega 6.3 models go to [MENTION=4551757]Silesh.Nair[/MENTION] post here and in his signature click on the mediafire "here" link and it will take you to the server and then select Roms folder and then select Beanstalk and you will see two selection of this rom and choose the one that is the newest and once downloading that go back to the main part of the server and go into recoveries folder and select which recovery you want to use as those recoveries all support kitkat and download the tar file version so that it can be flashed with odin, and remember if you flash the recovery to reboot directly back into the recovery as if you do not it will install the stock recovery again...this only has to be done once, and then it will retain the custom recovery.

The modem file in my post is actually from [MENTION=3499995]krazykipa[/MENTION] post here as in my post with [MENTION=3499995]krazykipa[/MENTION] in the quote here and that modem and TZ file i just made both files into a flashable tar file for odin from his files,but i will keep trying different things and see if this wifi problem can be fixed, but it should be working but things can arise and create problems also. ;)
[Samsung Galaxy Mega] krazykipa:
[MENTION=4482939]starmaster10[/MENTION] The files I posted are in fact NA3. They are smaller than your original dumps because the zero-padding was removed to make them flash properly.

[MENTION=5756210]Nubsta[/MENTION] If your WiFi isn't working after flashing those files, I'm not sure what else you can do... By the sounds of it you're running NA3 already with a matching kernel, system, and modem. I'd double check to make sure your build number and baseband version match just to be sure.
[Samsung Galaxy Mega] starmaster10:
Oh okay i wasn't 100% sure and i forgot that you took out the zero-padding part..sorry about the mis-understanding and i will edit my last post on that. :)

Update: Okay that post has now been edited. ;)
[Samsung Galaxy Mega] Nubsta:
build number :JDQ39.i527mvluamh1

base band:i527mmvlubna3

they are different...hmm is that why? lol
[Samsung Galaxy Mega] Patnad:
Is there a stock rom I can flash in CWM or can I modify the Odin one so It can be flashed in CWM perhaps?

I just want to make sure it wont change my Kernel or Bootloader and brick the phone..
[Samsung Galaxy Mega] Nubsta:
any luck with wifi yet?
[Samsung Galaxy Mega] starmaster10:
Okay i have put together a flashable zip file of the modem and tz file from my phone which both baseband and build shows NA3, this zip file can be flashed in the recovery and maybe it will correct the wifi problem. :)

File will not work for flashing at this time.
[Samsung Galaxy Mega] starmaster10:
Try this modem and TZ file and flash it with odin as this is the original modem and TZ file from MH1..as you build is still on MH1, and at least it might get your wifi working again. :good:

I527M-MH1.tar
[Samsung Galaxy Mega] Nubsta:
flash it with odin and nothing happen =) but thanx though mate. there is one lesson from all this for me...BACK UP YOUR WORKING ROM lol

k so i redo flash stock rom and flash mh1 file you just posted...i get image too large error again. so i flash a stock rom from sammobile and the previously posted I527M-NA3-Modem-TZ.tar and now it boot up with a ATT logo haha....i'm so confuse. BUT atleast it boot in again...ahhh i'm going insane lol

BTW when i start the phone...there's a yellow line top left corner say set waranty bit :kernel

here is the screen shot of the device info
[Samsung Galaxy Mega] starmaster10:
Well i cannot still figure out if you got the OTA update if i am correct how did the build no. stay at MH1 and the baseband update to NA3 it has me kinda of baffled as i never seen that till now, what kernel does it show in the about device screen..as mine is the knox one which is..

3.4.0-2416192

[Samsung Galaxy Mega] Nubsta:
i edit my post up there hehe...with a ss...thanx for all your help
[Samsung Galaxy Mega] starmaster10:
You still have the original kernel..then i cannot see how the baseband is NA3, did you flash a NA3 modem, but even so it should let you flash the original MH1 rom..that is really weird, try one of the other carriers rom for the i527m as they all will flash to the i527m. :confused:
[Samsung Galaxy Mega] Nubsta:
yes i did flash that NA3 file that you posted which fix the image size too large error...I will download another carrier and try a full wipe/flash again.:eek:...oh and forgot to mention...i never had the chance to do a repatition due to odin always fail...could that be the cause?
[Samsung Galaxy Mega] Patnad:
This totally saved my phone...!

I was on a custom rom with root also and I decided to give a try to KIES cause im trying to get back with the stock firmware or something very close to (with all samsung apps). Well KIES killed my phone at that moment, I had Knox 0x1 before KIES, after KIES i had 0xfffffffc

I used your file and it saved me, then flashed TWRP and I could restore my previous backup.

Anyone know of a way I could get very close to stock rom??! I'd really like gaining back all of the samsung apps..
[Samsung Galaxy Mega] krazykipa:
[MENTION=4635190]Patnad[/MENTION] Good to hear! There is currently no official stock ROM for NA3. The closest we can get is a prerooted system image. There should be a full image posted a few pages back by [MENTION=4482939]starmaster10[/MENTION]. Extract the system.img.ext4 and the boot.img from it and try flashing it. If it fails, let me know and I will post mine.

[MENTION=5756210]Nubsta[/MENTION] Your partitions are fine, the issue is you somehow have a mismatched kernel/system and modem. You currently have the MH1 kernel and system, along with the NA3 modem. We need those to match, all three NA3 or all three MH1. The important question is whether you have the Knox bootloader or not. Your bootloader version will determine whether you can pick between MH1 and NA3, or only NA3, Boot into download mode and if you see:

Knox Kernel Lock:

Knox Warranty Void:

Then you have a Knox bootloader which will only allow you to flash NA3. But, I predict that you will not see that text, which means non-Knox bootloader, and so you should be able to flash MH1 from whatever carrier you have, or NA3 if you feel like upgrading.

If you don't have a Knox bootloader, flash just the stock MH1 ROM, do not flash my NA3 modem files. If you do have a Knox bootloader, do what I instructed above for Patnad to flash the NA3 prerooted stock image.
[Samsung Galaxy Mega] Nubsta:
this is what it looks like...sry hands are shaky lol and low light..lol

i did flash the mh1 rom from this post...but then i get the image too large error and the only way to fix it so far is install your modem..so i'm guessing i gota install a na3 rom to fix this issue...
[Samsung Galaxy Mega] starmaster10:
You do have the knox bootloader forsure and I see you are at official status..the thing you might want to try if you like as this part is up to you..go to settings then the more tab and then into about device and go into software update and see if you can update as if you can get all to NA3 and get the newer kernel..then I believe your wifi will work properly.

But this may not update but worth a try if you like as you are basically stuck at NA3 anyways as you have the knox bootloader. :)
[Samsung Galaxy Mega] Nubsta:
Thanks guys

First of all i would like to thank both of you for spending all this time helping me. Secondly i would like to thank everyone else in this convo lol...its been a journey for me in this rooting/flashing business with my phone. All i wanted was to root my phone and kingo root didn't work. So after i accidently wipe system i get no OS installed which is freaking me out...I download the stock rom in this post and flashed...all hell break lose haha...then with you guys i learn so much about modem/kernel/bootloader/...etc and just now i installed CM11 and everything works flawlessly. Thank you all again and love you guys (no homo) :good::highfive: (and f*ck samsung support for suggesting me to go buy a new phone).
[Samsung Galaxy Mega] adulate:
mine is Still having the exact same issue. Where did you download CM11 from and was were the steps you did to flash it? Would it work to fix mine as well?

---------- Post added at 10:28 AM ---------- Previous post was at 10:20 AM ----------

Mine is showing the exact same info. build and base are different
[Samsung Galaxy Mega] Nubsta:
k so basically i'm trying to get the base band and build and modem and all that jazz on the same page....i can't change my baseband due to knox so the only way is to get the builds to match. I use this thread http://xdaforums.com/showthread.php?t=2566642 and all i did is follow that thread instruction word by word. I can't say it will work for you because i'm a noob at this hehe...give it a go and let me know....make sure you follow the instruction extra extra double extra carefully...XD
[Samsung Galaxy Mega] starmaster10:
That is awesome..and wanted to ask could you put up a pic of your download screen since you have CM11 installed as i am interested to see what it shows now...and enjoy your phone now. :D
