who is hesitant or looking for a guide on how to install Blu_Spark TWRP and Root the device.
The guide below will work 99.9% of the time. just follow the instructions carefully
Necessary Files:
Install OnePlus 6 Driver
Install Fastboot Drivers
TWRP Image
Magisk 20.1
twrp-3.3.1-x_blu_spark_v9.107_op6
Stock boot image thanks [URL="https://forum.xda-developers.com/member.php?u=6994095" @Akhil701[/URL]
Step 1: [dont do this if you have installed ADB and Fastboot already]
Install Oneplus 6, ADB and Fastboot Drivers from the link above
* Reboot PC after installing
Step 2:
Put
Code:
Stock Boot Image [boot.img]
twrp-3.3.1-x_blu_spark_v9.107_op6.zip and
Magisk-v20.1.zip
on your internal storage
Also Put
Code:

press enter then after that on your phone screen use volume up or down button to reboot to recovery
Step 8:
Once you have the TWRP Screen
flash the stock boot image [boot.img] in boot partition [DO NOT Reboot!]
now go back and flash the Blu_Spark TWRP and then reboot to recovery
Step 9: Rooting

Patched boot.img or why we need the boot image after flashing OOS10 via local update?

im not sure about that also. im just hesitant to skip that step. it might break something. thats why i added that step on this guide

Thnx, this was a very easy walkthrough.
Only thing I want to say is that not everyone knows how to flash the 'boot.img' through TWRP. Maybe you can explain that in more detail.

no patched boot.img you need
1. connect your OP6 to PC
2. flash TWRP (from mauronofrio) by fastboot from PC
3. reboot from fastboot to recovery
4. in TWRP flash stock img OOS, don´t reboot
5. in TWRP flash TWRP (blu_spark 9.107)
6- reboot to TWRP to another slot
7. in TWRP flash Magisk 20.1
8. reboot to system

I have noticed this too, probably they have changed somehow the system, even fastboot boot doesn't work anymore....
I had to install magisk via boot.img patching

Functionally on OOS 10.0.1 OP6 ?

So I was unable to flash the new OTA through twrp running on my rooted OP6.
As such, I opted to install the new OTA through the "local install" option.
That worked great. Settings area all the same. Bootloader still unlocked (I double checked).
Drivers are all installed on my Windows 10 PC.
However, no matter what I attempt to flash from command prompt I always get:
FAILED (remote: unkown command)
Does anyone know of a solution yet?
I have been reinstalling drivers and rebooting my PC with no luck thus far.
Any ideas?
Thanks in advance.
Update:
Whelp now that it is upgraded to Android 10 (and was wiped of all data when I locked and then unlocked the bootloader again) it will not allow me to downgrade back to Andriod 9 through the local upgrade option and since I can not get fastboot to accept any commands I am stuck now in Andriod 10 without the ability to change anything at the moment.

i knew it while reading but thanks to the screenshot you provided you saved me from sounding "user error" once again and piss of so many who prefer to blame things and others LOL
in short, wrong command, it's fastboot flash boot <image name>
BTW and since i'm already at it, if anyone has a Mac runniing 10.15 "Catalina" and fastboot is working from terminal, i'd like to learn how he/she's done it
just came to my mind to ask here since i have to use windows 10 under parallels desktop to fastboot flash my android stuff at the moment and of course that's just an "Emergency" choice for me, everyone using both platforms will understand

Wow. Okay.
This is becoming a comedy of errors on my part.
Oh boy now I am getting Qualcom flashdump messages...
Huh now it is just booting normal but not letting me get into the new recovery flash...
I got it all fixed.
Thank you everyone for your help and patience with my posts.

Does 10.0.1 still have the ability to do screen-off gestures for music? I like 10 but on my wife's 7t, either she didn't turn them on, our it didn't have them so I'm curious if there same thing is happening with this? I also noticed on her 7t, constant data problems when's switching from WiFi to data. Sometimes data won't come back and only a reboot solves. I know it's a bug on OOS 10 on 7t but wondering if it's a device specific bug or an Android 10 bug? Anyone having op6 issues with data not coming back when switching from WiFi?

WIFI problem solved!

Hi guys, sorry to resurrect this thread. I did everything in the correct order using 10.0.3.0 and after step 8 (reboot after flashing blu_spark) my phone gets stuck on blu_spark splash screen without any option to boot into twrp. Normal boot results in bootloop... Any ideas? Do I need to use different versions of twrp.img and .zip?

[Guide]Alcatel Idol 5 6060C Bootloader Unlock and TWRP[/Guide]

New From A-TEAM: lehmancurtis147​
ALCATEL IDOL 5 : 6060C​ACCESS FASTBOOT
UNLOCK BOOTLOADER
INSTALL TWRP
Special thanks to the mVirus Team for the reboot tool.
Ok, here we go!!!
Start fastboot:
1.*Unpack and launch the boot mode tool.
2.*Power off your 6060C.
3.*While holding vol- plug in device to PC.
4.*While continuing to hold vol- press power until the device starts and release power (not vol-).
5.*Once you see fastboot at the bottom of the device you can release vol-.
Unlock Bootloader:
Now that you are in fastboot mode, we need to unlock the bootloader.
Code:
fastboot oem unlock
Install Custom Recovery:
I forgot to mention I also built a working TWRP.img for this device.
1.*Unzip the recovery.zip.
2.*To install it.
Code:
fastboot flash recovery recovery.img
3.*then...
Code:
fastboot oem reboot-recovery
4.*Welcome to team win recovery!
DOWNLOADS:
This is the boot-mode tool:

twrp link:

NOTE:
Unless you remove verity (and a handful of other annonyances) you will loose twrp. Luckily, I've already built a replacement system.img to solve this. Once its working right I'll share it.
I have the system image working, but it's huge. Probably why system and vendor were split in android 8. It's a 4.6 gigabyte image so as soon as I decide the best way to host it I will post it.
In the mean time, the way to keep updated is our telegram group.

Recoveries
!!!ANNOUNCEMENT!!!
New Recovery Options Available​
I now have managed to build a fully functional Pitch Black Recovery Image and and Orange Fox Recovery Image (the later is built from mostly 9.0 branch) and will be making them available soon if I see that anyone is actually interested.

The recovery image files are compiled from source and not a Frankenstein type. So I can address any recovery issues (within the scope of reason).

Thanks for the thread!! I don't have this device but to my amazement, this utility booted my Alcatel 3t 8 tablet into fastboot mode and I was bootloader unlocked in seconds! I can't thank you enough. This tool should be shared around. It may just be the key to unlocking the bootloader on a plethora of 2018+ MTK devices.

Hi mickeybeats, I happen to have the Alcatel 3t 8 as well! I've been looking for a copy of the stock ROM/firmware everywhere and I'm unable to find it. Is it possible that you have a copy/know where I could download it? My tablet starting throwing up the feared "System UI has stopped" error and it seems reflashing stock ROM is the only way to fix it

I can confirm that the bootloader thing works for the 6058D model (MTK 6753)

For stock ROMs on Alcatel mtk devices, you need Sugar-mtk from Alcatel. It goes through the reflash process and as a bonus you can grab the firmware file from inside the flash tools program folders. The files don't use human readable formatting for the names but they end in either .bin or .mbn. A once over with a hexeditor should be enough to get a general idea of what they are. All the ones I've delt with had the boot.img label with a b at the beginning of the name and r for recovery, but gets a bit scattered from there.

Post your boot.img if you don't already have a custom recovery and I will build one for yours.

Good to hear.

Hi all!
Is there anything similar to 'boot-mode too'l for Linux machines?
What would be a proper command-foo for this task?
The usual method with adb/fastboot obviously doesn't work with
Alcatel IDOL 5 (6058D/MT6753).
To install TWRP on Alcatel Idol 5, you first need to unlock the bootloader.The process is a bit more involved for this device than it is on most others.

I don't know if it will work with wine. But you should be able to run it from a VM.

Don't be a idiot like me and accidently flash the recovery image on the Alcatel 3T 8. it will permanently brick the device and sugar-mtk will not restore .

Root Infinix hot 9

I am looking for an easy way to root Infinix hot 9 X655C. I have tried Kingroot but it doesn't work (I didn't have high hopes though). I was going to try Magisk but I can't find a TWRP for this particular model. I am also a noob.....like a big ole NOOB. Any assistance would be greatly appreciated.

ok stupid question. The link for the TWRP isn't working but I googled that particular file and it says it is for Infinix Hot2, is it still ok? I assume it is because that is the file they say to use in the article buuuut I just want to make sure.

Alright so now I've followed the directions but I get stuck at adb reboot bootloader. I do this and it goes into fastboot mode, fine. then I try to fastboot oem unlock-go it says failed can not be done in locked state. That means my bootloader is still locked yes? I can get into recovery mode via power and volume + but when I try to boot it into bootloader mode it gives me the fastboot screen. I have even tried restarting the phone and using the unlock code but it says waiting for device.
SOooo what am i doing wrong?

So I got the last issue fixed by entering fastboot flahsing unlock. I was able to flash TWRP but I can't open it. Any ideas?

Alright soo everything was flashed correctly no errors but when I try to open TWRP recovery I still get stock recovery. I have tried everything that article said and some other random articled via google. I am at a loss....

Infinix hot 10 play (X688B) stuck bootlooping to fastboot after orange state, help

i recently rooted my phone with magisk patched boot image and was working good after i restored my files, then it rebooted itself and now its stuck on orange state then going to fastboot mode, after that it loops back to orange state over and over again, please help

Reflash phone's Stock ROM to get rid off of all modifications you applied so far.

and what if i want to root the phone? flashing the stock rom gets rid of magisk, am i stuck without an option to root it? or should i install a custom recovery or cus os like calyxos?

new problem, i cant flash the stock rom using sp flash tool, gives me this weird error:
STATUS_BROM_CMD_STARTCMD_FAIL
any help?

I did this to my old phone if sp flash ain't working
"fasboot flash all slot a". if a/b partition
"fastboot flash all". if not a/b partition
and I feel like this method is faster than sp flash tool
edit:
lucky you could go to fastboot unlike mine can't go anywhere when I tried to flash my device it just reboot after 6 or 5 seconds ;-;

Does somebody have the stock rom for Infinix Hot 10 Play X688B?
There is the builder number X688B-H659ABCEFGHI-Q-GL-220109V524

I could only find this one site that has all of the stock roms of XOS. Not exactly the model number. Just a 'c' and 'b' difference

Did you fix it? If not I can help you

I think the stock roms would work.

Please I need your help on how you were able to root your infinix hot 10. I have the same phone and I was following YouTube tutorials they told me to use minimal adb and fastboot.. all the commands worked great but when I use command fastboot flash boot and paste my patched boot img it shows error... Unknown partition cannot determine image filename for boot img or so.

Can't Boot to twrp recovery (just displying twrp logo)

Hi guys,
just received from my sister a oneplus 6 and i tried to flash a new custom rom after updating the system. I was following the guide posted on these forum but, when i tried to boot from fastboot to twrp it just display endless the twrp logo. I tried to boot with an older twrp or blu spark but nothing, they all make QUALCOMM crashdump, just the latest never go past the twrp logo. Tried to search for someone with a similar problem but i couldnt find anything about my same problem. Thanks in advance.

Which android version are you? 9 10 11?

1. Unlock Bootloader (if is already unlocked, skip this step)
2. download platform tools and unpack
3. copy twrp img and installer zip to platform tools folder location
4. open cmd
5. reboot phone to bootloader
6. write in cmd fastboot erase userdata
7. then write fastboot boot twrp-file-image-name.img
8. twrp is booted, go to advanced and choos option Flash current twrp
9. if is done, then reboot to recovery
10. go to wipe option, choose format data and type yes
11. now you can flash rom using rom flashing instructions
12. remember, after done rom flashing, FLASH twrp installer

@Noob9496 hey dude thanks, i found Someone who had my same problem and I resolved too with fastboot erase userdata so I could had finally boot into twrp cause that was my main problem.
@croperas yeah that was the problem too, cause when I had finally my sweet rom, syberia os (the only android 12 available atm for op6) I tried to go back to the recovery but can't, tried reinstall everything but I couldn't so after some research couldn't find anything, but anyone who had problems with recovery almost always had problems with incompatible versions (like twrp for android 10 but had android 11) so I then realized it isn't still available a custom recovery for android 12 for op6. So after erasing everything its all fine. Thanks a lot guys really appreciated.

I have the same problem after flashing OO 11.1.2.2. I made a mistake flashing the wrong patched image to get rooted again but doing this I lost the access to twrp and now there is no recovery anymore. If I try to boot into any older version of twrp I receive a crashdump, if I try to boot to twrp 3.6.0 it gets stuck to logo. If I use the command "fastboot erase userdata" do I lose something?

Install the twrp installer directly from magisk

What I did was trying to install Lineage OS 18.1 (the latest nightly from Jan 11 2022) with Lineage OS Recovery. Following the official wiki I always got stuck in the lineage os boot animation. Never got past that. Tried to fastboot boot twrp.img but TWRP stuck on logo. I think I never tried to boot twrp with the userdata erased. I think I will try it.

Anyone trying to install the twrp, check out SHRP recovery for OP6/t. Boot the img and flash the zip from that thread. tested works with both OP6 and OP6t in OOS 11.1.2.2.
