I think it is only needed if encrypted. Not sure. I like to start fresh with wipe, to prevent creating problems.

Can make twrp backup and save to PC before wipe if you want.
[BLU R1 HD Guides, News, & Discussion] AndroidBR:
Do you think it's got something to do with Xposed module?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
Should be no problem. V21 is the updated non prime version so no ads to be removed.
[BLU R1 HD Guides, News, & Discussion] overthc:
What is the difference between v8.3 Mod and V21? Both of this post.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
Blu pulled 8.3 because app compatibility. After 8.4 fixed the problem they released 21 for non prime. So it should be same as 8.4
[BLU R1 HD Guides, News, & Discussion] emc2cube:
I took the plunge, did the following in one pass (in this order)

- V21 dirty flashed (no wipe of /data) over debloated rooted V12.

- SuperSU flashed

- updated debloat scripts flashed

- Cache/Dalvik wiped

Everything went well. I may do a wipe of /data at some point, not sure yet. TWRP still there after a couple of reboots.
[BLU R1 HD Guides, News, & Discussion] jloh1963:
I just tried your method mrmazak, and it looks good. I went from v12 to 8.4 using the v8.4-twrp-install.zip file reference in the first post of this thread. I just copied the file onto my external sdcard (hint: if you use adb you don't even have to remove your sdcard from the phone), booted into recovery (TWRP), wiped the dalvik cache a couple times before and once after, and rebooted. Whole process took about half an hour (I am including my app optimization time.) and putting the root back on the phone.
[BLU R1 HD Guides, News, & Discussion] rjcgamer:
I'm thinking I am having strange problems because my phone is encrypted and I didn't do a factory reset for a clean install. When I get some time to download my important stuff off the phone and backup my contacts, I will try doing a factory reset, install TWRP, and root and see if my strange issues resolve. Maybe I should not worry about encrypting from now on too.
[BLU R1 HD Guides, News, & Discussion] AndroidBR:
Okay, so I dirty flashed V21 a few minutes ago and it worked fine. But the issue is was having is related to Xposed. Every single time I try to flash Xposed the phone refuses to boot properly. So since I can't use Xposed with these latest ROMs I'll revert back to what I had. Can't stand to use a phone without it.
[BLU R1 HD Guides, News, & Discussion] Gizmosis350k:
Hello, I have a small problem. My R1 was originally on ColtonDRGs stock oem flashed via SPFT, vamps original twrp and it seemed to have updated to one of the later poison Amazon OEM roms with preloader botched.

I did some housecleaning involving factory reset. Failed attempt at running dirtycow exploit, and finally installing 8.4 OEM patched via twrp.

I promptly installed fm radio patch, downgraded preloader (unlocked bootloader from menu) and rooted using super su all in the same zip queue.

At the end of the day I have old preloader back, but I can't boot anything.

I then installed Colton's original v17 system, boot and recovery.img and I'm still bootlooping.

I have access to:- volume up and fastboot.

Recovery doesn't boot, nor does system.

Some important data is on the user partition.

Please send help.
[BLU R1 HD Guides, News, & Discussion] vampirefo:
You won't be able to boot with older preloader, you bit the bullet when you did an OTA, only fix is the flash preloader equal to or newer than your OTA.

LK will never let your phone boot, it's doing it's job, which is checking preloader checksum, if correct boot if not, block access to Android.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
Even when preloader and lk are change to older version together.?

That is the way I did It before.
[BLU R1 HD Guides, News, & Discussion] vampirefo:
Yes, that would work, but to my knowledge not possible.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I put a twrp script/ install zip only unlock tool that I have done it with
[BLU R1 HD Guides, News, & Discussion] vampirefo:
I see no way to do it, but if you can do it that's great for R1HD users, from what I saw in the OTA the LK was flashed at two points making it almost impossible to replace.

Oh well good job.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I saw that. And made assume that they used the uboot first to preserve the partition signature, but I am bootloader unlocked, so signature would be irrelivent.

I can be wrong , but worked , so I stopped asking why they did it the way they did.
[BLU R1 HD Guides, News, & Discussion] vampirefo:
The way it suppose to work, a user could fash preloader via twrp, this will cause the phone to bootloop, but phone will now accept splashtool if user then flashes LK, on boot up phone is dead won't even bootloop.

However if you can successful flash people's phone back to unlocked preloader, that it what you should do, just root isn't as good as unlocked preloader.

With locked preloader one major mistake phone is toast, with unlocked preloader one can revive their phone.
[BLU R1 HD Guides, News, & Discussion] Gizmosis350k:
Luckily mine was unlocked, that was a close one, fishing on eBay for one with preloader that can be rescued and a broken LCD to see what magic i can work
[BLU R1 HD Guides, News, & Discussion] roboman2444:
Just updated directly from v17 to this v21. Worked fairly smoothly, and i didn't even need to wipe before.

I did make a backup beforehand, as should anyone who flashes anything.

Something seemed to erase my recovery partition, and i needed to reflash TWRP. Pretty easy, just follow https://xdaforums.com/r1-hd/how-to/twrp-how-to-root-t3425677 steps 5-7

[MENTION=5312578]mrmazak[/MENTION] Is this ROM compatible with both the Prime Version of 1 GB of RAM and with the 2 GB of RAM?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
I only have the 2gb version, so cannot be sure. But because the build number of the ROM actually has the model number for the 1gb, I assume it should work.

Make sure to have a backup before trying though

Hello all I'm trying to flash 8.4 form TWRP 3.0.3-3 and it's just too fast .. when I mount system there is just 11mb written??

any ID what is happening?
[BLU R1 HD Guides, News, & Discussion] mrmazak:
twrp 3.0.3-3 is not the corrct recovery that this community has been using. Where did you get it?
[BLU R1 HD Guides, News, & Discussion] pas7771:
Sorry I made a typo I have 3.0.3-0 but still I can't flash I have a Blu R1 prime V6.6 and use tool v11 to unlock the bootloader successfully.

Is version 8.4 the right rom for me or what should I use that will work on this phone?

Thanks..
[BLU R1 HD Guides, News, & Discussion] mrmazak:
All the roms that are are this forum "should be" able to run on your phone.

safe v6.6

v7.4.2

v12

v17

v21

all interchangeable.

now there are also the non "stock" roms too, and they all should work also.

Wait.

just picked up on what you said.

when did you unlock with the tool?

did you follow all directions of the unlock.

I.E. :: did you allow the phone to reboot and do factory reset with the stock recovery before trying to flash new / different rom?
[BLU R1 HD Guides, News, & Discussion] pas7771:
I don't remember doing a factory reset with the stock recovery but I did a factory reset with the TWRP recovery.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
it should have been done automatically on first reboot after the unlock portion of the tool. unless you did not reboot and went straight into flashing twrp.

2 options that may help.

option 1

1 boot to fastboot mode

2 type "fastboot format userdata"

3 type "fastboot format cache"

4 reboot --either "fastboot reboot" if not work then long hold power button

option 2

1 boot to fastboot mode

2 type "fastboot boot stock-recovery.img"

3 if there is "trapped" command that needs to be run it should do so without input from you
[BLU R1 HD Guides, News, & Discussion] pas7771:
Failed on option 2 > cannot load 'stock-recovery.img' : no such file or directory

My situation is: I have a working fastboot cmd command and I also have a working twrp recovery

But everything roms I flash from twrp.. >>> it always goes back to twrp recovery..
[BLU R1 HD Guides, News, & Discussion] vampirefo:
Failed on option 2 means you didn't provide fastboot with the location of stock-recovery.img try again this time provide full path to stock-recovery.img

Patched from v7.4.2 custom version to v8.4, phone working smoothly so far.

The only problem I found is the "gmail having trouble with google play services. Please try again" error.

Tried removing google play services update, fixed the problem, but as soon as I updated in google play store. It's broken again. Still in the process of looking for solution...

edit: after some diagnostic, apparently updating google play services to the latest version 11.0.55 give that error for some reason.

Lost root - dirty cow fails

In May I rooted my (new) BLU R1 HD with dirty cow. Then I installed mrmazak's v8.3 ROM and was able to root it with dirty cow.

Today I flashed mrmazak's modified v8.4 ROM. However I am not able to root it, dirty cow fails at step 2 with "new_frp_md5 does not match".

UPDATE: Decided to skip step 2 and was able to complete the remaining steps.

Phone has root again :good:
[BLU R1 HD Guides, News, & Discussion] mrmazak:
You only need to do the dirty cow and unlock part once. Then if you change ROMs you can use the tool to install SuperSU if you want , but the first part like I said is only done the one time.
[BLU R1 HD Guides, News, & Discussion] Hack5190:
That explains it, thanks.
[BLU R1 HD Guides, News, & Discussion] shashank g:
I am on rooted with twrp installed. If i get it correctly, all i need to do is download the zip file in first post (v3.4) and install it using twrp and i am done? Do i need to do any other steps.

I see v21 is non prime version. But can someone let me know the big difference between prime and non prime as v3.4 has already the ads stripped.

Help greatly appreciated as i wanted to use this phone as daily driver without root.
[BLU R1 HD Guides, News, & Discussion] mrmazak:
If you have twrp, it is assumed you have bootloader unlocked, so no other steps should be needed. Of cource I suggest doing a wipe to prevent any possible conflicts.

v8.4 and v21 are practicly the same because the v8.3 had ads removed. But some have made statements to different exposed mods that work on v21 and not on v8.4. Since you do not want root I think that will not matter.
[BLU R1 HD Guides, News, & Discussion] Letitride:
Been running your "modified" v8.4 for about 2 months now with zero issues ... had 1 or 2 reboot issues with other Apps running, not a big deal as it is smooth & stable otherwise. No Amazon apps popping up whatsoever, rooted with Chainfire's latest V2.82 SR3 (and, Busybox v 1.26.2 installed to /su/xbin.)

Xposed Installer & Gravity Box running for those lockscreen & statusbar tweaks, and Viper4Android FX for sound enhancement and of course, AdAway. Still looking & waiting to see if I get the OTA prompt to download & install the latest v8.5 Rom update ... nothing yet. Use mainly as a backup smartphone, Freedompop 4G LTE (AT&T) sim in slot 1 and Google's Project Fi data-only LTE sim in slot 2 - it's mostly WiFi connected.

Postscript - Caution: if you are using mSD card (i.e. for external storage) it's best to power down, remove & set it aside, then, proceed with update as it will otherwise likely corrupt the files on the mSD card, resulting in a prompt to reformat the mSD card as being "error, unreadable, etc. etc." Once it is updated & running smooth & stable, re-insert the mSD card & power up/reboot again. In other words, be sure you backup anything & everything that is important on the device first.

Yes bootloaer unlocked. Great. Thanks. I will do a system wipe and then install this v8.4. Facing lag issues and network issues on 3g in India.(it constantly switches between 3g and 2g in some areas where there is perfect network signal). Hope network issue get resolved with this.

Does anyone face issues with mobile data, at least in India.(hope someone is using it in India). My mobile data switches between 2g and 3g very frequently while moving.

[BLU R1 HD Guides, News, & Discussion] mrmazak:
Your looking at the wrong version number. They all are android v6.0.

Look at about phone in setting menu. Scroll to bottom and look at build number.

You will need twrp recovery to install these, and you will need to have bootloader unlocked to install twrp., to unlock bootloader the trick is t use the "dirty cow" method.

that part is all wrapped into the unlock tool.
[BLU R1 HD Guides, News, & Discussion] G S W:
I'm sorry but the dirty cow method was a failure. I was not abe to follow those simple yet complicated instructions. And you said it was a tool but forgot to mention the (s) part as it wasn't an all in one newb friendly tool it was multiple batch files.

Oh and I tried this and it opened, said daemon connected successfully then closed really quick... I have ADB in 15 seconds installed... not sure what happened
[BLU R1 HD Guides, News, & Discussion] mrmazak:
lets start with details.

1. what version of the tool?

2. what version of os on pc?

3. what version of built on phone?

4. where on pc did you un-zip the tool to?(needs to be a location with write acces, so not in program folder or directly on root of C )

5. you said the long manual 5 batch script method failed. Do you have any details or feedback. It might help.

basics

1. phone must be connected and powered on in normal mode to start script

2. debugging must be enabled.

3. should test adb and fastboot drivers before running tool.

4. when done right the whole process from start to finish should be less than 5 minutes
[BLU R1 HD Guides, News, & Discussion] G S W:
1. Tool-V11

2. Win10

3. 8.4

4) desktop

5) I will get you some logs when I have a chance because now my phone isnt being recognized on my PC anymore and I deleted all the cow files so I cant re-produce it :/
[BLU R1 HD Guides, News, & Discussion] mrmazak:
sorry to inform you . but it will be irrelivent to continue. The dirty cow exploit does not work on your build version.

In build V 8.3 and above they patched the kernel exploit that allowed dirty cow to work.
[BLU R1 HD Guides, News, & Discussion] G S W:
I just want to remove the bloatware and ads, its 100% not possible in any way shape or form on 8.4? :/
[BLU R1 HD Guides, News, & Discussion] mrmazak:
It involves adb and the code "pm disable"

I do not have that version to check with , but should work

you would need to get a list of apps. then "pm dissable" all the ones you want to hide

this is general guide to do what you want. Not specific to this device so you need to do some work to determine what to disable/ uninstal

Modified 8.5 twrp install zip is uploading now. Link will be in OP.

I do not know what all the changes are, if any from last ota of 8.4

My modified 8.5 is of course based off of 8.4, off of 7.4.2, andd all have the ads removed with ota enabled. Only way we knew of this 8.5 was because of the ota enabled. But because of the continued reports of fota-ota being some type of chineese spy software, perhaps is best to follow the install with one of the debloate scripts. (or rename/ remove fota yourself)

In answer to your question

hey thanks for your quick response...to answer your question, YES, i found a way to install TWRP with adb the sdk version on V21 OTA. most of the work I did was taken from, ____guptainformationsystems.com/2017/07/how-to-root-oneplus-5-unlock-bootloader.html[/url]. it worked for my blu r1 hd with using R1-HD-Tool-V11 file i found on here. you can rename the recovery file twrp_***_recovery.img to just twrp_recovery.img for simplicity's sake. I thought I share this with you and the rest who are interested in learning on how to do this..

WARNING = if you do not know what you are doing....please research and perform at your own risk.
