Well for what you had ask how to do, it has nothing to do with kernel. So backing that up will do you no so much good. You asked about modifying the /system, that would mean you need a backup of that.

Wont work for me on 7.4.2!

This is new. So i installed ADB and all the needed components, and i *eventually* got the ADB working on Windows, And i read your "Instructions" text file and proceeded to do "adb devices", It returned my phone was connected successfully, (showed S/N), and i did "adb reboot bootloader" and my phone shut off, turned back on into "fastboot mode" but this time ADB failed to recognize my phone. :crying: Couldnt get any further then that. I wasnt able to test the tool yet for obvious reasons. I did use Ubuntu instead, But still the exact same problem. Wont recognize after i reboot it. Any help is appreciated!

unable to root,

Hi Guys I have a BLU R1 HD non prime version with custom build BLU_R0011UU_V17_GENERIC, and am unable to root my device.

Tried following the step via youtube video. Downloaded the software from rootjunky.com. i.e SP-Flash-Tool-R1-HD-bootloader-unlock.zip, TWRP_Scatter_R1_Prime. when I run the tool and select download I get a comunication error.

I then tried the unlock tool 2-2017. Downloaded the ADB + fastboot. ran the install.

opened a command prompt and rebooted device via commands adb devices. reboot into fastboot mode but device was stuck on fastboot mode on Device.

Kindly assist

---------- Post added at 10:44 PM ---------- Previous post was at 10:42 PM ----------

I then attempted to manually boot into fastboot mode and try to run the commands of the root tool but the command prompt closed thereafter
[BLU R1 HD Guides, News, & Discussion] mrmazak:
you make me a little confussed.

Of course adb will not reconnize phone in fastboot mode. That is when you use "fastboot devices" to check for fastboot connection.

If fastboot drivers are not installed will not recognize.

if "fastboot devices" does not show connected device check pc device manager and look for a device with the warning symbol on it. If that is the phone update that driver to android fastboot device(bootloader)
[BLU R1 HD Guides, News, & Discussion] 10033859:
Oh my good gosh... Im such an idiot.. I get it now. I havnt used fastboot in about 6 months, ive had all samsungs since my last flash.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
root junkies method was for prime version v6.1 through 6.5 . you are lucky that you didnt make yourself a brick,

so from your description it sounds like you have fastboot driver issue.

**NOTE**

the unlock tool should work for you but there have not been any confirmed uses yet. so remember that.

*****

there is comment on the op describing how to manually set driver for fastboot, please re-read it.
[BLU R1 HD Guides, News, & Discussion] ismailf007:
Hi I have manually updated the driver in computer management on my windows 7 pc but that made no difference to the fastboot.

if I go to command prompt and type fastboot devices it picks up the device. It alows me to reboot the device, what am I missing?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I do not know what part is sticking for you. Before fastboot was not recognized, now with drivers updated you said it recognizes, but did not say what you did after and what kind of error you get. Remember if you are trying to use the splash method it will not work anymore(until you are able to do the roll-back anyway)
[BLU R1 HD Guides, News, & Discussion] ismailf007:
Hi MrMazak

Please see pic attached. I have followed your instructions in the txt file for using the tool. After I run the dirtycow-unlock-tool.bat the command prompt dissapears.

Hope this give more clarity
[BLU R1 HD Guides, News, & Discussion] mrmazak:
If phone is still in fastboot mode that will happen. Need to be in android system for it to start.

And if this happens while phone booted up into android, check in the dirty-cow-tool folder for a folder called "working" and see if there is any text file inside.
[BLU R1 HD Guides, News, & Discussion] s.yogamurthy:
Hi All,

I tried rooting my device and noticed that the script is trying to run adb commands on fastboot and so it says no devices found. fastboot devices return reply. Please help.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
you need to be in android mode to start tool.

There are a few times that "adb devices" is issued to determine if "adb reboot fastboot" command is needed or not. the method works. If you are having trouble I do not think that is it.

error at step 2

tried V9 tool and getting error at step 2. Both Adb and fastboot are installed and verified as mentioned in instruction file.

Version : BLU_R0010UU_V8.3_GENERIC 14-04-2017

Here is the content of NEW_FRP_MD5.txt file.

md5sum: can't open '/data/local/test/frp': No such file or directory

Also tried V10 but the bat file is not showing the tool menu...
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I thought that was going to happen.

V8.3 just came out today. I need to change the title of the thread/ tool. It will not work with V8 apparently. The tool uses an exploit referred to as "dirty-cow" and is related to a bug in the kernel. The kernel was patched in November to block the exploit. And now that update has been pushed to this phone.

You are now stuck unrootable. At least til someone e can figure a way around it.

I elected to follow the UNLOCK TOOL (2-2017) for ALL versions except 8.3 of BLU R1-HD thread.

Made it through steps 1 & 2 of the dirty-cow-tool V11 with no issues or errors. Step 3 returned the following:

With the following on R1-HD's screen:

The phone powered off and rebooted fine - but I have no idea where to go from here. Any help is greatly appreciated.

PS: This guide is the one i used to enable developer mode, but there are no options dealing with “OEM unlocking” after developer mode has been enabled.

Environment Information

phone: BLU R1-HD Amazon

non

prime refurb w/16 GB

build: ROM BLU_R001UU_V6.4_GENERIC 10-07-2016 00:10

security patch: June 1, 2016

PC: windows 10 w/"15 second adb + fastboot install TOOL" installed

UPDATE: Tried the process again - this time when step 3 failed I manually entered Fastboot mode (by rebooting phone while pressing Volume up and Power button simultaneously) - this allowed me to finish the process through 5 / 1 (Flash SuperSU).

You need root to write to system.

Unlocked BLU R1HD 2gb/16gb Prime edition

One small observation...I noticed that my Google Play Store reverted to an older version but it says its up to date (layout is different) It used to have library tab that made it easier to restore apps previously downloaded and showed the date I last updated each app. Any thought on how to correct this?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I have three phones, my daily has the layout with the library tab,

My test phone, the one i just did a reset on does not have the layout with library tab. And they both have same version of play store installed.

This link has a description of the new play store layout.And says you should get that screen back eventually.

[MENTION=5312578]mrmazak[/MENTION] - Thanks. I saw something on a different thread about clearing playstore cache and force stopping it so it reboots. Tried that and its back with library tab.

Thread wasn't for my particular problem but hey....whatever works! Thanks again.

Any idea how to get rid of double lockscreen when custom locker is applied? System locker only has "swipe" option instead of "none".
[BLU R1 HD Guides, News, & Discussion] shagberg:
Thank you

[MENTION=5312578]mrmazak[/MENTION] - Wanted to let you know that your tool worked flawlessly in unlocking and rooting my Blu R1, and I really appreciate the effort that you put into creating it - thank you so much!

Also, I read through this entire thread, post by post, before tackling it to make sure that I didn't brick it. The amount of help that you gave to the community in working through their issues is to be commended - you are truly a saint.
[BLU R1 HD Guides, News, & Discussion] Serenitybs:
[MENTION=5312578]mrmazak[/MENTION] - I seem to have run into an issue with app permissions. I can't change permission for any of my apps like I could before. A message pops up repeatedly saying that a screen overlay is detected but I denied access to drawing over apps to all the available listed apps. I tried rebooting several times but screen overlay is always detected. How can I fix this please?

BLU R1HD 16/2 rooted and debloated using the method in this thread.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I don't know, never heard of screen overlay before. I googled *screen overlay detected" and, now I understand your comment: "denied access to drawing over apps to all the available listed apps. "

But I wonder if you have selected to show system apps in that list. -settings-apps-"gear icon"-draw over other apps-"3 dots menu"-"show system"
[BLU R1 HD Guides, News, & Discussion] vampirefo:
I have see the overlay several times, allowing it was the only way the app could work on top of other app.

Example the fake GPS app to work over Pokemon go, requires overlay to set on top of Pokemon go to navigate.
[BLU R1 HD Guides, News, & Discussion] Serenitybs:
Yes I even disabled the system apps but still nothing. I hope nobody else is having this issue. I was so frustrated trying to give WhatsApp access to mic so I could make a phone call I just gave up and decided to take a leap and try out your "non-rooted modified V8.3". So far it's working and no screen overlay issues.

I saw on that thread that you mentioned "wiping" when installing the 8.3 update. I didn't do that when I initially unlocked the 7.4.2 so maybe that was the issue idk. I guess I'll never know cause now I'm using your V8.3 and it's flawless so far. Thank you!
[BLU R1 HD Guides, News, & Discussion] slowgo1234:

[BLU R1 HD Guides, News, & Discussion] Trilkhai:
[MENTION=5312578]mrmazak[/MENTION] - I'm running into a problem with all Linux versions of your unlock tool on my new R1-HD (v7.4.2) from Amazon. The tool gets all the way through Steps 1 & 2 without problems, then:

All the log reports each time is "Dirty-cow started" followed by "Phone Failed unlockability check."

Thanks for any suggestions of what I can try next!

(Side note: the duplicate mkdir /data/local/test line in Version 9's cp_comands.txt consistently caused a false report of "[W] cp_comands.txt File pushed to phone do not match md5." Once I removed the duplicate line -- after re-downloading the tool, trying again, and finally making sure the md5 hash for the phone's copy matched -- the error vanished.)
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I think maybe there could be a bug in this section of code.

On my ubuntu vm it works but maybe on your system it does not.

I added numbers to the line to show line that your error message came from.

260	$FASTBOOT flashing get_unlock_ability 2> "working/unlockability.txt"
261	sed -i '3,4d' working/unlockability.txt
262	sed -i '1d' working/unlockability.txt
263	sed -i 's/[^0-9]//g' working/unlockability.txt
264	value=$(cat working/unlockability.txt)
**	265	**	if [ "$value" -gt "99" ]; then
266	echo "Unlockability shows phone is unlockable"
267	echo "continueing"
268	else
269	echo "phone shows that it is not unlockable yet"
270	echo "press enter to exit"
271	echo "Phone Failed unlockability check" | adddate >> log.txt
272	read \n

The lines are supposed to check in fastboot mode the output from "fastboot flashing get_unlock_ability" , and output to a text file then remove (sed) all the information except for the unlock-ability number.

then check to see if that number is greater than "99"

this is what the unlockability.txt should look like before the sed lines

...
(bootloader) unlock_ability = 16777216
OKAY [ 0.000s]
finished. total time: 0.000s

the sed lines should be doing the following in order written.

(sed -i '3,4d' working/unlockability.txt) removes lines 3 and 4

(sed -i '1d' working/unlockability.txt) removes line 1

(sed -i 's/[^0-9]//g' working/unlockability.txt) removes everything else that is not numbers 0-9

If you manually do fastboot flashing get_unlock_ability

and get a value greater than 1 , you can remove those lines from the .sh or fix them if they code is wrong.

of course if the output is 0 then the step 2 process will need to be trouble shot.

I was able to connect to phone via adb & fastboot - got stuck with W7 drivers

But now when I click dirty-cow-tool.bat nothing happens, no command window with instructions.

Do i need the phone in a certain mode or not even connected in order to have the dirty-cow-tool to operate?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I see in a different post you got past this. But yes phone should be in normal Android mode and powered on. First part on my script checks some data through adb and if it finds it to be a match then tool will start.

But having nothing happen at all is not normal.
[BLU R1 HD Guides, News, & Discussion] leandrox:
Hi, I need some help here. I went through steps 1 and 2 with no problems. I got to step 3 and the phone is stuck with a "Fastboot mode" message and cannot continue. PC screen says "no adb connected devices".

If I reboot the phone and try again, it goes back to such state. Any ideas?

I installed adb+fastboot from links, and I'm using the latest version of the tool.

EDIT: more info. When I go through step 2, the program does its magic but the phone never moves from the usual BLU splash screen. Never reboots or goes back to start screen.
[BLU R1 HD Guides, News, & Discussion] OldSkewler:
Hey,I should be the last person trying to give advices here but since I went thru the process on two phones very recently I could share one thing: in between steps I realized that I had to boot the phone normally, enable Developer Options and enable USB Debugging again - I believe because one of the steps resets the phone and to continue you need to re-enable full access. After doing that I was able to continue the tool process. This was not clear anywhere on the topic or the instructions with the files, so it took a while for me to figure out what was going on. Once done, I run again the .bat file and continued to the next step.

Maybe you already knew this and it is evident, but in any case I'm sharing it.

Good luck

[BLU R1 HD Guides, News, & Discussion] leandrox:
Thanks. I don't think that is the problem here because when I reboot dev options and debugging are on.

The problem comes when after the phone reboots in step 3. It locks in "FASTBOOT mode" and the tool fails to find and adb device connected...

If I reboot the phone and try again, the same happens.
[BLU R1 HD Guides, News, & Discussion] OldSkewler:
Maybe that is not applicable to where you are in the process or either one of us is not communicating clearly.

Either way, at some point in the process you will need to boot the phone and go over the USB Debug mode enabling it again. Just keep that in mind and good luck. Hopefully someone more knowledgeable will chime in.

Sent from the other side of the line
[BLU R1 HD Guides, News, & Discussion] leandrox:
Well, I managed to make it work. Thing is drivers worked well when the phone was on android, but did not once it was off or on fastboot mode. I went up and down, left and right trying to set W10 to recognize every state of the phone and that somehow made it go through all steps.

Debloating and rooting all succesful!

Rooting BLUE R1 HD without Amazon Ads

I have a BLU R1 HD that does not have the Amazon Ads. Custom Build Version BLU_R0011UU_V12_GENERIC 27-06-2016 14:13 will the instructions here on how to root work for this version?

Also, I have a patch that is waiting to be installed it says Update Information Version number BLU_R0011UU_V17_GENERIC_6.0_20161115-1444 (Release Date 2015-11-15). Should I install that before rooting? After rooting? Or not at all?

Thanks.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
That update will block your ability to root. so if you want to root do not take the update.

There is also another update that came out few days ago. Making it V21

From V12 you can use this tool, but do not need to use the dirty cow part. because on v12 there is a "toggle switch" inside developer options to allow oem unlock. The toggle switch is missing on the prime version, that is what the dirty cow is doing is working around the missing switch.

So you can enable developer options and turn on allow oem unlock and enable adb

then use the tool starting at step 3

Android security patch level is : August 5,2016

To do all of this took me whole week, because this was my first time doing it and I’m a total beginner.

R1HD 7.4.2 - entire process complete but Amazon ads and apps are still present

Hey, I am new to android. I completed the entire process successfully but at the end, phone still has ads and amazon apps that i can not uninstall. Is this expected or do I need to do something else now?

Is there a way to check if phone is unlocked and rooted? I am on v7.4.2 on R1HD prime phone.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
If there is SuperSU app in app drawer, that logically means recovery installed, which logically means bootloader in unlocked.

Reasons

1. SuperSU is installed with custom recovery. Not stock recovery.

2. Only way for custom recovery is if unlocked bootloader.

You can download app from play store that needs root , see if it works. Or a root checker app

As for Amazon ads, I think the debloat tools stopped working on v7.
