[Miscellaneous Android Development] Techguy777:
I've been looking around and talking to people with experience and this is going to be risky and a lot harder than normal. I have heard you need a DA file because it's a secure boot but I've also read that secure boot is a locked bootloader that's why it's secure. So in my opinion it should not need a DA file unless you don't unlock your bootloader and your trying to flash custom firmware. I'm not going to say im 100 percent I'm not I just use common sense. If you think about it a firmware pull off the stock boot the kernel should be the exact same then magisk patches I think to disable some security and add super user permission. Then you flash the stock patched boot img back to the phone it should work because it's stock firmware with a tweak. If you flash with S P flashtool with the phone powered off it should work. The DA file to me doesn't seem necessary why would the phone unlock bootloader if you still needed a Day file there would be no point. It's a risk if you don't want to see your pic phone maybe end up broken don't do it. Me personally I enjoy figuring out how to root the phone and tweak it more than I enjoy the phone to use for Normal stuff. I'd rather have a rooted KitKat old low spec phone then a new Android pie stock firmware that's not root able. That's another thing every time you update with there ota updates they will patch security and make it harder to root. I think pie is over rated crap it doesn't have any new features at all except your recents menu scrolls left and right not worth the bugs the tighter security. I don't own the phone if I did I would have tried what I think will work and if it breaks I would just say oh well it's s phone not the end of the world. I've rooted a dozen different phones and there all different models which have taught me how to do about everything. Never bricked 1 or not got it rooted not 1. I rooted a Dell venue with a locked bootloader and no recovery by using a tethered recovery from my laptop then I found the custom recovery and bootloader unlock flash file but I got it done without it. The locked bootloader is the first security if it's unlocked you are preparing you phone for root the phones security should disable and allow to flash stuff.

My Blu studio m5 plus had no firmware to download I used

1.Wwr tool and made a scatter file and stock rom dump

2. I installed magisk manager on Blu m5 studio and patched boot img that I pulled from Wwr tool with magisk.

3. Put the patched boot img into a folder on pc renamed it back to just boot.img with the scatter file I made.

4. Turned phone off had vcom drivers already installed use s p flashtool to flash just the new boot img hit download then hold volume down button for my phone plugged it into USB on pc. Mediatek device have a button that activates the phone without turning it on to flash with sp tool. The button is different on different models mine was volume down.

5. Sp flash tool said ok in green so I unplugged and booted up phone went into magisk manager rooted 17.1 stable.

6. I tried again now to unlock bootloader because fastboot oem unlock will bring up the bootloader unlock but it disables my volume up button so I can't unlock it. Still locked bootloader Even today.

7. I got the stock recovery img that I made with WWr tool and used the hovatek twrp Porter and made a twrp from stock in about 2 seconds the program does all the work for you no compiling source. Disable antivirus software on computer when you're using these programs. Make sure you're phone has no fingerprint or pin code obviously think no security to gain root I always factory reset it and then enable oem unlock and USB debugging. Another tip is if you pull your stock it should be about the same size as the phone like my phone is 8gigs so stock firmware should come out about that and it did 7.63gb recovery and boot will be about 16mb took 15 gb on pc because Wwr tool makes one full rom bin about 8gb backup then makes scatter backup with partitions so another 8gb or a less. So you need plenty of room if you're phone has 32 gb it'll need like 64gb get it. So use a clean phone with no apps to save space on the user data back up cause that's your biggest file.

8.put the new twrp recovery into a folder on pc with a copy of scatter file and it turned phone off and used s p flashtool to flash the new recovery just like it was stock unchecked all options on s p flashtool except recovery it should only have recovery checked to begin with because you shouldn't have anything else in your folder. I waited said ok in green unplugged phone hold volume up then power button to immediately boot into recovery so twrp sticks. Worked made a backup fadhed Xposed viper.

So I could be wrong and you could need a da it's up to you guys to try it. I would search to see if any of those phones that needed da file had unlocked bootloader if they didn't we know that's why they needed da file. Maybe someone on xda would know but it would be easy **** if there was a stock rom zip. You could try brick reflash stock your set. Good luck guys I hope this helps.

If you guys have any questions feel free to ask. I'm not going to be one of those so called developers that ignore the question because I don't know the answer. There's no one that can be 100 percent certain of everything with these phones except the guy that developed the software for it. Xda is filled with a lot of fake developers all they do is take open source code and recompile it and put there name on it. That's nothing more then coping someone else work if there's a bug in the rom 99 percent won't be able to fix it until the open source codes are updated and a real developer fixes it. There's also the locked bootloader rule but there's exceptions to the rule and it doesn't work like they say but they aren't going to say that because if you brick your phone you'll be like it's your fault so they always play it safe. Don't be a little ***** either it's you trying stuff and it's your fault if you mess it up. The bootloader unlock is only for custom firmware like a recovery or rom not for flashing period because flashing is just installing something well you can install apps without unlocking your bootloader right? Yes and sometimes phones let you install root with out unlocking your bootloader and sometimes not it's not 100 percent. I've had 3 devices that allow root without unlocking bootloader Dell venue 3830, lg tribute ls660, and now the Blu studio m5 plus. Lg tribute I used kingroot with flashify to flash twrp never unlocked bootloader. The days of one click root are gone after 6.0 mm you will need to flash root and usually you'll need a unlocked bootloader to do it. Xda is loaded with copy cats that don't know **** and it's crap I think rom building is overrated if I get a pc that I can use I'm going to learn to do it and build twrp and kernels because that's more important than rom you need recovery and kernel for root and backup plus it's harder to make and I like s challenge.
