Has anyone tried the firmware.mobi website with CF Autoroot and uploading the images? I am uploading mine right now. I found also the netherlands january patch already there but beibg on dec I don't want to risk an even higher bootloader
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Well guys.. It seems that I have made some progress here.. take a look:

I have flashed the CF autoroot from the January patched firmware because mine seemed to not upload and it flashed successfully. I immediatly enter in the donwload mode and guess what.. my knox was triggered and is now one. Next action, I did was to flash twrp, it flashed successfully!! However, I got an error that only official binaries are allowed to be flashed once I tried to enter in the recovery mode. Then I flashed the sboot provided previously but then I started getting the error of recovery image signature check failed.. bla bla bla... I will try more combinations. The thing here is the time consuming when I have to reflash the whole firmware to start all over with different combinations.. but I think we are getting there!!!

OMG guys... OMG OMG.... I did it!! I installed the TWRP!!!!! I will post later on how to do it!!!!!
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
When I flashed it I forget to uncheck autoboot so it's automatically booting...I tried to goto recoverymode but the message popup so I click it...then bootloop....

How? Now you have twrp? And no error or some problem?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Well.. I did.. I wiped data so I could mount it and flashed magisk successfully... I was rooted and my phone booted fine.. However after that I tried to access twrp and I got the error of the only official binary... I am trying to redo the process but now it is failing... I do not know what did I miss.. I guess I had to swipe to allow modifications after I wiped data.. that was the step that I missed. As soon as I get everything working and normal I will post the exact steps to avoid confusion
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
It seems you didn't reflash the sboot.bin after reflashing the firmware.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
The process that I did was without the sboot. It was with an image.tar that I downloaded from the firmware.mobi website, but it is not letting me flash it now.. I don't recall doing anything different than what I am doing right now, but now it does not let me flash it. I am trying with the sboot, and I got same error than before

This is the file that I used:

https://drive.google.com/open?id=1XF3q8xGAZdc1GBxfhIzoVYEJHuwy9bny

After I flashed that my system booted normal. I went to download mode and flashed the twrp without the autoreboot and it booted successfully and then I did the data and magisk thing.. Booted again and it booted sucessfully.. however went to the recovery again and I got the binary message, tried to flash it again and got the binary message also.. since then.. have not been able to flash it

---------- Post added at 06:08 PM ---------- Previous post was at 05:38 PM ----------

Ok guys... I give up... could not do it again... if someone does it.. please share it.. hope all the info I provided works for someone...
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
I would suggest that you start afresh with the stock firmware. Flash the sboot.bin, reboot immediately to download mode, install cf_autoroot then reboot and see where that gets you.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Already done it.. It gets me to bootloop.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
what firmware did you use? first you flashed image.tar.md5 then twrp? after that when you boot into twrp it's ok? then you flash magisk trhu twrp?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Exactly.. my firm is QLA is Colombia December sec patch.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
you have backup of custom rom?try to restore it... for me i can't flashed image.tar.md5 it's failed... need to flashed sboot.bin first befor image.tar.md5... and after that it;s bootloop ...
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
No, I don't as I have never installed one.. I guess my error was that on twrp I did not swipe to allow system modifications.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
try it again?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
I guess I could mate... I tried everything but it does not let me flash the CF autoroot again.. I realized that even current binary is custom.. system keeps being official.. and the first time that I made it, system was custom.. maybe I need to trigger that but it is not letting me
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
CFautoroot modified your boot image which is why you have the custom binary notification.

If you flash the stock firmware everything should go back to official.

.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Yes... it is already official... no more tries on my side today haha, maybe tomorrow I keep trying, but for today I have exhausted everything what I have thought off..

---------- Post added at 09:20 PM ---------- Previous post was at 09:17 PM ----------

I am pretty sure we need to trigger system to custom.. in that way we do not get the bootloop for the warranty thing..
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
It's more likely cf_autoroot patched dmverity in the boot image allowing the device to boot.

It's also usually necessary to factory reset in stock recovery first then boot directly to download mode.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] Jemec26:
Yes! The thing is getting it flashed .. i don't really know how did it happen the first time. But well.. i will wait to see if someone else would like to go to.the adventure hahaha

Unable to restart your device.the integrity verification has failed.you need to reset your device to factory default settings.this will erase all your data.

haha I don't know what made me think a newer one would make a difference... bootloader is upgraded, now is Device 4 on Jan patch, just for you to be aware of... I guess I am staying with uncle sammy tw for a while now haha, not even previous sboot flashed.. hope you guys can root yours.. good luck mates!
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
Ok flash this with ODIN. It contains the sboot and boot from the combo firmware. The boot image is unmodified as it should already have integrity checks disabled in the kernel and should be permissive.

See if boots WITHOUT flashing TWRP, if it does then try flashing TWRP with auto boot disabled. Immediately force boot to TWRP after flashing TWRP.

COMBINATION_A520FXXU3AQL1_sboot_boot.tar

This one contains the same boot image but modified to remove the integrity check AND forced encryption if the above doesn't work.

With this one ensure that you boot to recovery and factory reset the device to remove encryption after flashing the boot image.

[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
when i flashed combination_sboot_boot.tar, it does stack at samsung galaxy A5 and when i flashed modified_boot.tar it does bootloop...
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
out of luck i tried so many times.... i think the problem is the twrp when it flashed then reboot... it does bootloop? if there's modify twrp for decsecurity update what do you think?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
Need to remember the boot images are actually for MM, so there was a chance they wouldn't boot NN.

I will have to modify the NN boot image instead.

Can you post the boot.img from the A520FXXU3 NN firmware?

Also just to be clear, does the device boot OK with just the sboot.bin from the combination firmware and everything else stock?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
stock at samsung galaxy a5 logo... when i tried goto recovery,device updating then no comand... i do factory reset but still no comand.

i upload N bootloader in google drive

[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
I actually needed the boot.img not the bootloader. However never mind I've obtained it elsewhere.

I've modified the boot image and removed the dm-verity check, removed forced encryption and also adb should be enabled with write access.

Flash this after the sboot.bin then see if it boots after factory resetting in stock recovery. Please note boot will take around 10 mins after a reset.

[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
OK, I guess the next step is to simply repack the boot image without any changes to see if it still boot loops as it may simply be the repacking that is causing the bootloop.

However just to be clear, are you factory resetting the device after installing the boot image?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
Even I did factory reset still bootloop...

If I flashed sboot.bin + twrp then boot my device ok...but message on screen verification failed before homescreen. Need tap reset... even I tried go into recovery mode it can't be...
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
OK I will repack without any changes and see how that goes.

If it turns out even repacking without any changes causes a boot loop then we have a problem.

---------- Post added at 06:46 AM ---------- Previous post was at 06:39 AM ----------

@kobejor

Ok have repacked without any changes at all, could you test and report if it boots?

still bootloop
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
Then there's the issue if it boot loops with absolutely no changes.

It may be a simple case of unsigned images are unable to be flashed.

However I will take a deeper look at the image headers to see if Samsung are doing something funky.

Are there any messages on the device when the boot image is flashed?

It seems like Samsung have upped their game. Previously we could lie to the bootloader by appending the SEANDROID footer to the boot image, but it seems even that doesn't work any more. :(

The second message regarding twrp must be without sboot.bin flashed?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] kobejor:
With sboot.bin....you can't flash twrp without sboot.bin flashed first...

Try this if you're OK with losing stuff stored on internal storage.

Flash sboot.bin posted earlier then boot normally. Reboot to stock recovery then factory reset your device.

From recovery reboot to download mode and flash twrp with auto reboot unticked.

After flashing finishes with a PASS in Odin, immediately force reboot to recovery.

Post the results please.

Has OEM_UNLOCK disappeared from development settings?
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ts_firehawk:
So, to make things clear before I try anything: I need to flash this, reboot to stock recovery, reset my device from there, reboot to download then flash TWRP without auto reboot ticked then boot into TWRP? After that, what do I need to do? Reset again? Or just boot normally?

Will this works with any firmware? Because I'm currently running A520FXXU3BQL3 and I hope to have no problems with wrong bootloaders (again).

Another question: does the bootloader have anything to do with the settings app? When I was messing around I flashed some bootloader I found in some thread and I got some weird entries in the settings app (Roaming T and another one to select an network) that weren't there before I flashed it (this is why I ask if the file you provided works with any firmware).

Thanks for your work, btw. I'm missing root because Sammy's software is so full of crap and it really bothers me that some of them I can't even disable.
[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] ashyx:
I dont think it works as the boot image is from marshmallow and won't boot on nougat.

I can upload just the sboot.bin to flash in ODIN. Then try the procedure below.

Make sure FRP is off (OEM_UNLOCK enabled) Factory reset in stock recovery.

Flash sboot with odin, auto reboot off.

After flash and odin reports PASS manually reboot to download mode again (don't let the device boot to the OS).

Flash TWRP in ODIN with auto reboot off.

After flash immediately reboot to recovery.

[T-Mobile Samsung Galaxy S6 Edge+] mudflap2.0:
Hey guys, I know I'm a little late in getting into the whole world of tweaking this guy and development has promptly stopped awhile ago. But here's what's up... I've gone into the general s6 edge plus thread on XDA and downloaded the pixel ROM, and this ROM is absolutely amazing (but data doesn't work, 4glte or call) I've figured if I can extract the modem from any nougat built for the T-Mobile version I can just install it and have data working for this ROM. Oh and btw this ROM was apparently for the g928c so that probably explains a few things. Okay so I've actually had a chance to extract the modem.bin from a nougat build for T-Mobile but I'm having the up most difficulty in implementation. I can't seem to Odin install as Odin stays checking the file and never installs. Right now I'm out of ideas and it doesn't help windows botched the ease of using ADB in favour of windows powershell. Everything doesn't seem to work any more like it used to... Sideloading... Flashing doesn't seem to work... I'm getting off topic but if you guys have any input feel free to reply to this thread or hmu on my Instagram Anthony_vibez

I had to click View All on the theme and then I could choose the default theme.
