Unable to Root AT ALL

So I wanted to install a CM ver on my mother's Redmi 1s and first thing I have to do is root the device right?
<image>
I have tried downloading several SuperSU.zip from multiple sources, including here at xda forums and the miui forums, to no avail.
Every single attempt has been a failure using the Stock Recovery that comes with the phone.
Fine then, I'll just use a custom recovery. I then connected the phone to my laptop via USB and used the sdk I downloaded.
After typing this line >>adb reboot bootloader, the phone booted into a screen with the fastboot bunny, all normal yes?
Then I typed >>fastboot oem unlock, but the image below doesn't show up on the phone
<image>
Instead, the command prompt just shows a few lines of the process completing
<image>
I continued to enter>>fastboot flash recovery customrecovery.img into cmd with the custom recovery image IN the platform-tools folder in sdk. Cmd again shows a few lines saying that the process completed.
<image>
However the phone still stays on the screen with the fastboot bunny, even after rebooting and then entering recovery mode, it is still the stock one. I have searched everywhere on how to root this phone but they just showed to install the SuperSU.zip using the stock recovery or the sdk method. If anyone could just help me solve this issue that would be great. If you need more information that I can provide regarding the issue feel free to ask. Thanks in advance !
P.s. Due to xda preventing me from posting outside links since I have not met the threshold, anyone who needs the pictures can message me privately.
Edit: Ah yes, I should also mention that I have tried using the stock Updater app to install the SuperSU.zip as well but that doesn't work. Also, I have tried using King Root and Kingo Root as the easy way, same thing.

Find the TWRP image for our device. I don't prefer the fastboot method; flashing TWRP and then the SuperSU zip is a whole lot more convenient as you don't need a computer.

But doesn't flashing TWRP without PC (with an app) requires the phone to be rooted to begin with? Or is there any workaround method?

Then use Philz recovery. There's a sticky in the general section that provides a link to such a guide using Philz. After rooting you can flash TWRP.

Nope, still doesn't work. Tried using the stock recovery to install update.zip and also flashing the .img via sdk, both doesn't work. I'm again out of options.

before do this backup your device
you can install custom recovery with official fastboot rom.
download any official fastboot rom for your device (stable or beta does not matter)
download twrp .img file for your device
rename your recovery image file to "recovery.img"
extract the fastboot rom
go to "images" folder in extracted fastboot rom
overwrite recovery.img file with your downloaded file
flash the fastboot rom with mi flash.
wait for the installation to complete
setup your device
turn off your device and go to custom twrp recovery.
after that you can install supersu or any custom rom via twrp.

I hope you have checked this post

For me..I started with a zip file containing the custom recovery (TWRP) it was named as Update.zip I got it from a tutorial I googled (noob, I know)...and I flashed it using stock recovery (Redmi 1s don't have locked bootloaders, I guess) and then I had Custom recovery installed..I made a backup of MIUI (it was unrooted, stock) and then flashed the CM 12.1( it was the latest then). Then there was no looking back.

Unable to recover OxygenOS on Oneplus3

Hello everyone,
This morning, I wanted to recover OxygenOS on my Oneplus3. I'm currently running Cyanogenmod 13.
I used the following guide: "[GUIDE] How to Unroot your OnePlus 3 / 3T and go back completely to stock" (Since I'm a newb, I can't post the link. But Google will get you there)
I booted into fastboot, issued the fastboot flash recovery recovery_op3.img and fastboot oem lock commands from my Linux termina, and rebooted in recovery mode.
In recovery mode, I then erased the cache and all that, selected the "Upgrade android from USB" and issued the adb sideload ota.zip command. This is where my problems began.
After running the command, I got the error "error: protocol fault (no status)". I tried to look this error up, but couldn't find useful information.
I started to panic a bit, fearing that my phone would be bricked. However, after booting back into fastboot mode, unlocking OEM, and rebooting, my phone would boot back into Cyanogenmod 13 (A clean install).
So now I don't have a bricked phone. However, I really would like to go back to OxygenOS, so my question is whether anyone knows how to solve my problem.
Summary:
Running Linux (Debian 8) on my PC;
Running Cyanogenmod13 on my Phone;
Want to recover OxygenOS, but adb sideload gave me "error: protocol fault (no status)";
Tried running the adb sideload command as root, however that did not work;
Can still use the Cyanogenmod13.

I've seen that error once before. I had to disconnect the phone, kill the ADB process, reconnect the phone and restart ADB to get it to work.
That worked for me. Hope that helps.

Hey, thanks for responding.
I forgot to mention that I also tried killing the adb process several times, using the adb kill-server command and by killing the process sending SIGKILL.
Another thing I tried was using another Debian machine, which is my laptop. Still, those things did not solve my issue.

Never relock your boot loader, most bricks are due to relocking.
Flash twrp, flash oxygen os ,boot, enable everything,if you want complete stock, flash stock recovery ,flash oxygen os boot to complete stock os.

Backup youre working rom..
First, you need unlocked bootloader.
1.Flash twrp 3.0.4.1 or twrp-3.1.0 x v.26 blu_spark. Reboot to recovery.
2.Clean flash (wipe data-dalvik-system-cache) Oxygen OS, since you come from a custom rom. Flash SuperSu or Magisk, if you want root. Reflash recovery. Reboot to recovery.
If youre phone does not boot in recovery, press Power till phone vibrates. Press vol. down & choose:
1. Select Bootloader. Flash recovery from PC. Safest way to flash recovery.
or
2.Select recovery. Reflash recovery. Reboot recovery.
After you are sure that you got a working recovery reboot to system.

Thanks for responding.
Since I don't understand everything yet, I will spend this evening looking up everything in detail, before I start giving it another try. Do you perhaps know of a tutorial about this specific situation? I don't want to bother you by questioning everything you stated in your instructions. They seem clear enough to be able to be looked up on Google :laugh:

Thanks for responding.
By the steps after "if you want complete stock", do you mean that I should keep the bootloader unlocked, and then perform the same steps as in the tutorial that I used?
EDIT:
@ null0seven: I found these steps online as I was looking up some things you said (I don't have much time since I will celebrate eastern with my family today)
Rooted Users or users with ROMs other than OxygenOS having new bootloader (Official CM 13,CM 13 Based ROMs dated later than 04 June 2016,H2OS Marshmallow)​
Step 1 :- Download the OxygenOS 3.0.2 full zip from the top of the post.
Step 2 :- Boot into TWRP.Wipe Dalvik,System,Data and Cache.After that,flash OxygenOS 3.0.2.
Step 3 :- [OPTIONAL] Flash SuperSU from here :- https://www.androidfilehost.com/?fid=24459283995297946
Step 4 -> Reboot System.
Of course, this is about an old version of OxygenOS. But it looks the same as you said.
I think this, combined with your instructions, will make it a bit clearer. Still one question: What do you mean exactly by flashing?

[GUIDE] Reflash LEX727 With Stock ROM After LEX720 Update

I flashed the latest 20s Chinese ROM to unlock my bootloader and had trouble getting back to LEX727 19s ROM with a working SIM card, this what I did to fix it.
Goal: Get LEX727 back to 727 ROM from any Chineese Variant (LEX720) with a working sim card.
Logic: We need to get the phone back to as stock as possible so that we can flash dr4stic's ROM That will update from CN5.8.018s to US5.8.019s. First we need to install CN5.8.018s, but we need to do it from stock recovery, to get stock recovery back we use a TWRP backup made by suhridkhan, then copy the CN5.8.018s zip, rename it to update.zip and allow the phone to do it's thing It will take quite awhile to flash the stock CN5.8.018s ROM, but when its done we can then install dr4stic's ROM, but first we need custom recovery again, since we flashed stock recovery when we used the TWRP backup. So we reflash custom recovery (I recommend GrossoShop's TWRP as that is what worked for me, however others may work). Reboot into fastboot, fastboot flash recovery the GrossoShop TWRP, then we go back to recovery. Now we can install the upgrade ROM. Once the upgrade ROM is installed, we can reboot and we'll have a completely stock version of the LEX727 ROM with Stock Recovery. (oobe state)
STEP 1 INSTALL WORKING ROM
1. You will need a working ROM to copy the TWRP unzipped files to the phone (figure this out on your own, but you should already have something that works)
STEP 2 STOCK RECOVERY
1. Restore this TWRP backup
1. Send the unzipped files to your phone in TWRP/BACKUP/<Device_ID>/TWRP. (You need a working ROM to do this with USB, you can try adb pushing the .zip and adb shell unzipping but I had permisison errors. and found it easier to just move the files unzipped)
2. Reboot into recovery, Advanced Wipe everything except Internal Storage (where your backup is)
3. Restore from the TWRP backup, before restarting, do a factory reset wipe and dalivik.
4. Reboot, and you SHOULD be in the LEX727 Rom, however your sim card will not be recognized depending on the modem firmware you came from.
STEP 3 GETTING DOWN TO CN5.8.018s
1. Since we have stock recovery, we can now use it to flash down to the right Chineese ROM version for dr4astic's ROM update to work.
2. Setup the phone, and copy LE_ZL1_LEX720_CN_5.8.018S.zip, then rename it to update.zip
3. Install the update through the phone settings or browser. (It will take quite a while 15ish minutes)
4. The phone may reboot into an endless boot loop where it just keeps redoing the same startup flash, To get past this reboot into recovery and perform a "Clear data" wipe.
5. You should now be in the stock version of LEX 720 5.8.018s
STEP 4 USING THE UPDATE ROM
1. We need to flash a custom recovery again (I recommend GrossoShop's as that is what worked for me, however others may work)
2. Reboot into fastboot and flash your recovery software
3. Wipe everything, data included and reboot back into recovery.
4. adb push the update ROM and install it, wipe dalvik and do a factory reset wipe before restarting.
5. When you tap restart system from TWRP the phone will vibrate for about 7ish seconds, dont do anything, just let it do its thing. It will reboot and go to a black screen, then finish rebooting.
(this is perhaps the most risky step as we are returning to a stock ROM with stock recovery and might loose our unlocked bootloader)
6. You should get everything back to stock ROM with working SIM card and an unlocked bootloader.
note: I will be saving local copies of all the files required indefinitely, so if any of the above links break, I will re-upload.

How to upgrade O+5T to OxygenOS 5.1.0 when rooted with stock recovery?

Greetings. I received the OTA update (which I did not install!) on my OnePlus 5T today. I'm on OxygenOS 5.0.4 with magisk installed, phone is rooted, bootloader unlocked, stock recovery (no TWRP).
What's the right path to upgrade to 5.1.0?
I'm experienced with the command line and have no problems with it.
Based on my ideas, I think the path should be:
- Download full Oxygen OS 5.1.0 Full Zip
- Start TWRP using adb
Code:
fastboot boot
(which TWRP version?)
- Wipe dalvik and cache
- Flash the downloaded file
- Wipe dalvik and cache
- Flash magisk
That's it. Am I missing something? Do I need to reinstall magisk as specified as last step? Which TWRP version should I use (from the official website?)?
Thanks for your help :good:

Please go through the dedicated update thread that ive made for the update
https://forum.xda-developers.com/oneplus-5t/how-to/official-oxygenos-4-7-2-7-1-1-ota-t3709265
The thread has all the instructions and files needed to update. As far as twrp is concerned i recommend latest codeworkx or or bluspark recovery. The links are available on the thread.
Feel free to post on the thread if you have any further doubts.

Thanks @Funk Wizard , I read that thread (I linked it in my post) but it mentions "For Stock Non Rooted Users with Stock Recovery" and "For Rooted Users with TWRP Recovery" while in my case I'm rooted with STOCK recovery, which doesn't fit any of those 2 sentences. Which one should I follow?

As you are rooted you can flash the full zip from stock recovery that would remove root or you need follow and flash via twrp. If rooted stock recovery is no good TBH and i recommend staying on TWRP.
You can flash twrp from fastboot and then follow the instructions on the flashing post.
In case you dont need root anymore you can just flash the full zip from stock recovery. It will remove root and you will stay on stock recovery. In both the cases, use the full zip to flash via twrp or stock recovery.

No good? Please be more specific, why it's no good? From my understanding keeping stock recovery with magisk installed and bootloader unlocked allows me to pass all SafetyNet checks, which is very helpful if you don't want to deal with apps complaining that you are rooted. I can easily boot to TWRP as long as I can plug my phone into my computer by just using the fastboot command. The only downside I could see is if I brick my phone and have usb debugging disabled, I can't fastboot from adb.
Flashing TWRP would make me fail SafetyNet checks, which I'm not interested into.
After I flash the full zip, do I also need to flash the OTA update?
Thanks by the way, basically the only real "special" thing I need to do is install Magisk again after flashing.

Flashing twrp doesn't break safety net. So it's upto you if you want to stay on stock recovery with no additional benefits or on twrp.
Also, if have full time zip then you don't need to flash ota zip again.

That's good! I'll definitely flash twrp in that case.

@sshivampp Sorry to resurrect this thread, but looks like it's important. On TWRP website itself it's stated that installing TWRP would break dm-verity. What's the consequence of this? https://twrp.me/oneplus/oneplus5t.html

Can't Install TWRP

I've unlocked my Bootloader and all via beta-test program from DCUnlocker. I wanted to install TWRP & Magisk and I have following every step available from sir Supersonic's guide, but whenever I opened recovery, it always shows stock recovery (eRecovery) even though my CMD states that the flash recovery was succesfull and I never let my phone boot up in order not to replace the TWRP just like any android devices normal recovery procedures.
