Need help getting ADB to recognise my device? - OnePlus 7 Pro Questions & Answers

So I may be doing something totally idiotic, but I seem to be stuck at the most simple part of unlocking my bootloader.
I follow this to step 2:
https://www.xda-developers.com/unlock-bootloader-root-oneplus-7-pro/
when it says "Set up ADB" I follow the link to this:
https://www.xda-developers.com/install-adb-windows-macos-linux/
until I get to step 7. When I enter the command 'adb devices' I never get a serial number nor a prompt to allow or deny USB Debugging access. I never get see my device’s serial number in the command prompt.
So doing a bit of digging I have looked into ensuring my ADB and One Plus driver was installed correctly, and I even purchased a new data transfer cable to make sure that wasn't the issue.
I check my device drivers and see get an error in my ADB Interface driver, but after following a few tutorials I'm still lost as to whether its updated or if I'm doing so incorrectly, or if that's even the problem.
Any direction would be appreciated.
I am running Windows 8.1 and my device is Android 10, model GM1915.

Hallelujah!!
Finally found a way to manually install the correct driver from a tutorial on visualgbd{dot}com, so now my device is recognised.
I had to find where my drivers were being default downloaded since they weren't in the place the tutorial indicated, but that was the only hitch.
SO. On to the actual unlock. :fingers-crossed:

So I need help.
I followed an XDA video tutorial which was a bit difficult for a newbie, but I think I did everything correctly up to installing TWRP.
I got to the point of flashing my ROM and jumped to the Eelo website instructions:
- Go to main menu, then tap Wipe.
- Now tap Format Data and continue with the formatting process. This will remove encryption as well as delete all files stored on the internal storage.
- Return to the previous menu and tap Advanced Wipe.
- Select the Cache and System partitions to be wiped and then Swipe to Wipe.
- Sideload the /e/ .zip package:
- On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
- On the host machine, sideload the package using: 'adb sideload filename.zip'
I followed this and while the package did not sideload, I beleive my recovery partition was wiped I seem to be stuck.
I'm at the point where I feel I need to Flash OEM Stock and start over, but I am getting a bootloader loop.
Really need help. I feel at this point I'm going to start making things worse as I look at various tutorials and whatnot.

In case additional information is helpful:
My device does not show up in my device list, but it is detected with "fastboot devices".
I attempted to flash TWRP with "fastboot flash boot <TWRP.img> and it writes to 'boot-a'. But when I then try to boot into recovery mode, instead of booting into TWRP I enter the fastboot screen.
I tried using mauronofrio's Tool All In One to flash stock ROM and possibly fix the partition, if thats what the problem is, but I cant tell it did anything.

Bricked Idol 3, need help recovering

I installed the OTA update last night and it's just looping through the "alcatel one touch" and "smart move" screens. It's been like that for hours.
I need assistance in getting into recovery mode, and hopefully getting my files off the device.
I have downloaded android-studio and am about to install it to get adb and fastboot, and have downloaded the drivers for the idol 3. At this point when it's plugged in, my computer doesn't recognize the device.
If you did not have usb debugging enabled BEFORE the boot loop installing adb and fastboot now won't do you any good. Are you still able to get into recovery and is it twrp or the factory recovery? Without a direct way to get the phone into bootloader regretfully the only solution is to send it in for warranty repair (or replacement via your credit card if you paid that way under purchase protection)
Are you trying to remove the data to prevent access by others or because you need the data? Did you make any backups to external sd or copied to the pc?
I as well am stuck in bootloop. Was able to get into factory recovery and reset phone several times. Still no luck. I have a TWRP backup, but how to I do a temporary boot into it? Only option available in factory recovery was to sideload via ADB, but no luck using fastboot commands there. Phoned Alcatel and they have referred me back to Amazon. Amazon only wants to refund me, won't exchange! Of course I bought at the pre-order price. Any help would be greatly appreciated.

The factory reset killed you....if you had usb debugging enabled prior and had not done a factory reset (which kills /data) you could have possibly gotten to an adb shell long enough to do an adb reboot bootloader. The problem is there's no way now to get you into bootloader....you can't get to it from recovery (factory).
If you purchased it by credit card you might see if their purchase protection (typically 60-90 days) allows a claim submission for a replacement....in this case they would cut you a check for the cost of a replacement after mailing in your old one. That's the only solution I see to remain at the $199 price.
You could also see if amazon will issue a $50 credit to your account in addition to return to allow for repurchase. Unlikely but possible.
Ok thanks for the input and advice. As a last ditch effort, is there a way to create or modify the twrp file as a "signed" zip file so that I could boot into it via stock recovery. This was how I rooted my old Galaxy S2, although it was a CWM recovery.

Nothing so far has worked in that regard...in fact I created a update.zip using "zipme" to replace the build.prop that another user says the factory recovery refused to process.
Without a full factory rom to pull needed info in or the source code to compile one we can't do some of the things which would "save" the device.

Can you post a screenshot where the option is? I'm not doubting your word but perhaps he's looking in the wrong place? I'm back on TWRP so can't look in the stock recovery myself.

There is no option for screenshot while the phone is in the stock recovery. I need a camera to take a picture of the menu. I can do this later. The menu however looks like this:
Code:
reboot system now
apply update from ADB
apply update from sdcard
apply update from phone storage
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery log

If it's right off the main page like that then I can confirm it's not on the 6045. It's been one of the main issues with folks bricking their devices...if their rom gets messed up and they have factory recovery they have no way to get into bootloader to do anything to repair the device. Seems alcatel needs to add the reboot to bootloader to our recovery. I wonder where we could report that.
Is there a way to "lock" recovery so the updates cannot replace twrp? TWRP allows adb access and reboot to bootloader.

This is a snapshot from the recovery menu of 6039y.
The short answer of your question regarding the "lock" is ... no. If a longer explanation is needed ... this is from the update file, a link to which was provided by you:
Code:
if ! applypatch -c EMMC:/dev/block/bootdevice/by-name/recovery:18393344:f9062580503eb61b315a5d12c5c6b3bb133aa4b2; then
....etc.
what it does is to check the sha1 sum of the recovery partition and if the sha1 sum doesn't match to f9062580503eb61b315a5d12c5c6b3bb133aa4b2 will continue with an overwriting of the recovery partition and then will apply a patch. It can't be changed because the whole update will fail.
yep no bootloader
I've got reboot to boatloader on main page from stock recovery on my 6045k

Back to the "lock" question. Probably it is possible the OTA update to be slightly modified and then to be flashed through the TWRP recovery (there is an option in TWRP to skip the signature verification ... the verification will fail if the zip file is modified). But I prefer to wait for the OTA update of the 6039y, as I want to perform some tests with the upgrade.

I am in the same boat as OP re the state my Idol 3 (6045i) is currently in. I also unchecked superuser but did not unroot completely before installing the update. I have not yet done a data wipe through recovery though. Unfortunately, back when I rooted the phone I did NOT check the box telling the phone to remember the computer/RSA key for future use. As a result, now when the phone is stuck at the white/animated Alcatel boot logo I can see the phone under adb devices, but it shows as unauthorized.
One thing that did seem odd, was browsing through stock recovery when trying to browse to apply an update from either phone storage or the SD card, no files are showing up at all. All it is showing is the folder root ( /.. ) in both instances and nothing else. Even after I attempted loading several system update and twrp images (in .zip and .img formats) on the SD card from my computer, once loaded in the phone none of the files show up through stock recovery. Is this SD card not compatible/formatted wrong or is something else going on?
Is there any current method to gaining access to the phone via adb manupulating the adbkey files in the $User$/Home/.android folder? I do currently have the adbkey files on my Mac from connecting the phone previously. I'm assuming these files are uniquely generated hashes?
That is ridiculous if the 6045k has bootloader access from recovery and 6045i does not. What would be the reasoning for this?

Does the sha1 sum of your recovery happen to match f9062580503eb61b315a5d12c5c6b3bb133aa4b2 ? If so it could solve some issues but why do I suddenly think all 3 models have their own recovery?

adb reboot bootloader won't work even with it showing unauthorized? If you can get into bootloader you can fix /system without messing up your /data (don't wipe data or you lose adb entirely...you may figure out how to add the correct hash if we can find how it's generated)
Here's some info on the hashes you might find useful taken from: http://nelenkov.blogspot.com/2013/02/secure-usb-debugging-in-android-422.html
Secure ADB implementation
The ADB host authentication functionality is enabled by default when the ro.adb.secure system property is set to 1, and there is no way to disable it via the system settings interface (which is a good thing). The device is initially in the OFFLINE state and only goes into the ONLINE state once the host has authenticated. As you may already know, hosts use RSA keys in order to authenticate to the ADB daemon on the device. Authentication is typically a three step process:
After a host tries to connect, the device sends and AUTH message of type TOKEN that includes a 20 byte random value (read from /dev/urandom).
The host responds with a SIGNATURE packet that includes a SHA1withRSA signature of the random token with one of its private keys.
The device tries to verify the received signature, and if signature verification succeeds, it responds with a CONNECT message and goes into the ONLINE state. If verification fails, either because the signature value doesn't match or because there is no corresponding public key to verify with, the device sends another AUTH TOKEN with a new random value, so that the host can try authenticating again (slowing down if the number of failures goes over a certain threshold).
Signature verification typically fails the first time you connect the device to a new host because it doesn't yet have the host key. In that case the host sends its public key in an AUTH RSAPUBLICKEY message. The device takes the MD5 hash of that key and displays it in the 'Allow USB debugging' confirmation dialog. Since adbd is a native daemon, the key needs to be passed to the main Android OS. This is accomplished by simply writing the key to a local socket (aptly named, 'adbd'). When you enable ADB debugging from the developer settings screen, a thread that listens to the 'adbd' socket is started. When it receives a message starting with "PK" it treats it as a public key, parses it, calculates the MD5 hash and displays the confirmation dialog (an activity actually, part of the SystemUI package). If you tap 'OK', it sends a simple simple "OK" response and adbd uses the key to verify the authentication message (otherwise it just stays offline). In case you check the 'Always allow from this computer' checkbox, the public key is written to disk and automatically used for signature verification the next time you connect to the same host. The allow/deny debugging functionality, along with starting/stopping the adbd daemon, is exposed as public methods of the UsbDeviceManager system service.
We've described the ADB authentication protocol in some detail, but haven't said much about the actual keys used in the process. Those are 2048-bit RSA keys and are generated by the local ADB server. They are typically stored in $HOME/.android as adbkey and adbkey.pub. On Windows that usually translates to %USERPOFILE%\.android, but keys might end up in C:\Windows\System32\config\systemprofile\.android in some cases (see issue 49465). The default key directory can be overridden by setting the ANDROID_SDK_HOME environment variable. If the ADB_VENDOR_KEYS environment variable is set, the directory it points to is also searched for keys. If no keys are found in any of the above locations, a new key pair is generated and saved. On the device, keys are stored in the /data/misc/adb/adb_keys file, and new authorized keys are appended to the same file as you accept them. Read-only 'vendor keys' are stored in the /adb_keys file, but it doesn't seem to exist on current Nexus devices. The private key is in standard OpenSSL PEM format, while the public one consists of the Base 64 encoded key followed by a `[email protected]` user identifier, separated by space. The user identifier doesn't seem to be used at the moment and is only meaningful on Unix-based OS'es, on Windows it is always '[email protected]'.
While the USB debugging confirmation dialog helpfully displays a key fingerprint to let you verify you are connected to the expected host, the adb client doesn't have a handy command to print the fingerprint of the host key. You might think that there is little room for confusion: after all there is only one cable plugged to a single machine, but if you are running a couple of VMs, thing can get a little fuzzy. Here's one of way of displaying the host key's fingerprint in the same format the confirmation dialog uses (run in $HOME/.android or specify the full path to the public key file):
awk '{print $1}' < adbkey.pub|openssl base64 -A -d -a \
|openssl md5 -c|awk '{print $2}'|tr '[:lower:]' '[:upper:]'
We've reviewed how secure ADB debugging is implemented and have shown why it is needed, but just to show that all of this solves a real problem, we'll finish off with a screenshot of what a failed ADB attack against an 4.2.2 device from another Android device looks like:

Just tested using adb reboot bootloader again and this is the result: error: device unauthorized. Please check the confirmation dialog on your device.
Something else I tried was running fastboot commands in the narrow window that the phone initially boots (black screen with Android logo) but that didn't seem to work either. I tried:
fastboot reboot-bootloader
fastboot -i 0x1bbb reboot-bootloader
fastboot -i 0x1bbb devices
I noticed if you plug the phone into the computer via USB while the phone is off, it will briefly power on to the Android logo/black screen before flashing the battery status once and turning off. Is this an opportunity to send fastboot or adb commands to the phone?
I'll try messing with the adbkey stuff later when I have time to dig into it.
There is a tool from Alcatel (TCL) which can perform upgrades of the device from a Windows PC. You can try it if nothing else helps. There are two COM ports available under Windows when the device is powered off and the USB cable is connected to the phone. This tool use them to perform some checks on the device and probably will continue with an upgrade (it says that all of your data will be wiped after the upgrade etc. so there is a possibility to overwrite everything with a stock image) ... there are instructions how to work with it. The link is from the French support section of Alcatel. Despite that the program has support for 6039 and 6045 is not clear for which of their versions.

You can't do fastboot commands until the phone is IN bootloader....so you'd have to do adb reboot bootloader
adb devices

It is possible the program to download these images from a server.
I found another interesting thing. The device has a download mode. It is activated when the phone is powered off and connected to a PC. You must wait the display to turn off after the charging battery symbol and then to press and hold both volume keys, after which to press and hold the power button (without releasing these for the volume). But still don't know what to do in this mode. No device is detected on my Linux box when the phone is in this state. Probably I should try in Windows.
Also when the Alcatel upgrade tool was trying to detect the phone I'm almost sure that one of the COM ports was
Qualcomm HS-USB Diagnostics 9006
there is a lot information for other devices how this can be used to unbrick your phone, so this is a some start. The images which the people flash through it are in raw format.

Install TWRP and root LG v10 H901 T-Mobile

Download
Search for TWRP recovery for LG V10 H901 (File: twrp-2.8.7.0-h901.img (31.7 MB))
Backup Apps and Data
While this process should not wipe any of your data, a backup is highly recommended. Once you install a custom recovery like TWRP, make sure you backup your system, data,etc. from the recovery. It will be helpful in case anything goes wrong.
Prerequisites
This guide is compatible with LG V10 H901 only. Do not try it on any other devices or variants.
Unlocked bootloader is required to install a custom recovery like TWRP on your device. Click here.
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
Install Motorola USB Drivers on your computer.
Open Settings> Developer options and enable USB Debugging on your device.
Go to Developer options and enable Allow oem unlock.
How to Install TWRP Recovery on LG V10 H901
Download the recovery image file. Extract if in case a zip file. Now transfer the file to your PC where you can easily locate it.
Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.
Now power off your device and unplug it from your PC.
Boot into the bootloader or fastboot mode. To do so, press and hold volume down and the power button simultaneously for 5-6 seconds. When you see the bootloader screen, connect your device to the PC using a USB cable.(Choose fasboot if option is available) Alternatively, you can also issue the following command through your cmd or terminal, while connected to the PC in order to boot into the bootloader.
"adb reboot bootloader"
Navigate to the location where you have placed the recovery file. Rename the recovery file to a simple one, like recovery.img. While the folder with recovery.img file is open, hold shift key on keyboard and right-click on an empty space and select “Open command window here” option to launch a cmd window.
Now issue the following command in the command prompt to check your device connectivity
"fastboot devices"
Now flash custom recovery. Issue the following command for that.
"fastboot flash recovery recovery.img"
Custom recovery will now be installed on your device. Now boot your phone in recovery mode. You can do this by turning your device off and then press and hold volume down and power keys at the same time. Or you can simply enter the following command.
"fastboot boot recovery.img"
Once into the recovery, you can backup your current ROM, data, EFS and more.
Once you have installed TWRP, you are all set to install custom packages onto the device’s system. Alternatively, while on Linux or Mac OS, you can issue “./fastboot flash recovery recovery.img” command to flash the TWRP recovery.
Root
As you already have TWRP, simply flash the SuperSU file (version 2.56) to gain root access
@TheJesus @KAsp3rd, thanks guys for everything you've done over the past few days. no shade to @joe01gun but if people are going to use these instructions make sure you search the rest of the forum for what thejesus and kasp3rd put together to get us to this point - definitely appreciated. thanks @joe01gun for putting these additional instructions together.
Your post says the following:
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
yet, there's no link to the necessary files to "unzip" them. Any suggestions?
Thank you for the help, but where do we get fastboot set up on our PCs? Yes, this is getting confusing with the steps outlined above. I followed the first step and had to take out the battery because I was stuck in fastboot screen with small tiny text in the top left that didn't respond to any manipulation with the volume keys on the back of the device and wouldn't restart any way until I took out the battery.

Your condensed thread is more convoluted than the actual development thread which also includes the links to everything.
I'm still wondering why you have install Motorola USB drivers for an LG phone..

The one on development is straightforward and I managed to make it done.
If you don't lock the bootloader back, you will see bootloader unlocked when starting up.
If you have root enabled file explorer, you should remove /system/priv-app/adaptclient folder to avoid annoying root request from adapt.
Please use the main dev thread for instructions on what to do, found below. Having duplicates for what is essentially the same thing can cause confusion and just takes up unnecessary space. So I have closed the thread.

How to unroot, lock bootloader and go back to stock?

For background, I have Verizon pixel 2 and am using a Mac.
I went down a massive rabbit hole last night reading through these forums and all the posts and was able to unlock bootloader, flash the January OTA and then root by doing the modified boot file with magisk. (interestingly enough the booting into recovery gives me red ! Over a dead Android and I could not load the OTA that way, nor did the adb sideload OTA comand work either, I had to push the extracted walleye img and then the zip file as discussed in one of the steps in some other thread here)
So anywho, in the end I now have a phone that gives me 2 errors when it reboots, one for unlocked bootloader and another for root telling me something is wrong with my phone and i should contact the manufacturer (which I read on here is normal), but my biggest issue is that my ADT alarm app doesn't work anymore (even if i check it off for hide in magisk). I feel like the root is just not worth it for me and I want to revert to completely stock image, even if it resets my phone and I have to re back everything up all over again like did when i had to do the unlocking of the boot loader.
So -- What are the steps I should take?
1)uninstall magisk from magisk manager?
2)delete magisk manager?
The above will unroot me, correct?
3)Do I push the stock boot image file onto the phone?
4) do I have to repush the latest OTA walleye image and zip file onto the phone again?
5) do I then do the adb reboot and do the flashing lock command (same command i did to unlock the boot loader) to lock up the bootloader and reset to stock?
If someone could be as explicit as possible in correctiong or validating my steps above it would be much, much appreciated.
I don't want to do any more unnecessary steps in flashing things than is needed so if I have extra steps above (perhaps 4 is not needed?) Let me know.
Thanks
Proceed with Caution
I am not an expert by any means, but can speak from personal experience. I was in the exact same situation as you. I followed the detailed steps to unlock the bootloader on my pixel 2, received similar issues, and the same prompt when the phone rebooted. All that to say proceed with caution.
My thoughts on questions 1 & 2: I personally wouldn't recommend you remove or delete magisk from the manager. When I did i had to reinstall it via twrp. My phone functioned fine, apart from the error at reboot.
My thoughts on questions 3 -5: When I followed the steps on XDA for your questions here I ended up bricking my Pixel 2 with locked bootloader from Verizon. Probably an error on my part, but wouldn't want someone else to go through the headache, hours of issues, and then an expensive paper weight.
My suggestion would be to:
1. Leave your phone as is and attempt to trouble shoot the app or apps you are having issue with
2. contact Google support on your phone and see if they would replace it
3. wait for an established method to unroot the pixel 2 here
Thankfully Google replaced my phone due to the error after rebooting, prior to me bricking it. I knew I had a replacement phone coming. So I attempted to go back to stock and that is when I messed it up.
Note sure this is exactly what you were looking for, but hope this helps you.
Dozens of posts with hundreds of pages on how to root but no advice on how to go back to stock cleanly?

Your version is Verizon which is making things more complicated. Generally when the bootloader is unlocked, you just hit flash-all.bat and then relock the phone. Given that the Verizon I'm not sure.
So you are on stock ROM with all these apks loaded ? If you go to settings, then do a factory data reset, you'll reset the phone back to stock and completely wipe the phone and return it to stock, at that point you can go into bootloader mode and relock.
Again your bootloader is unlocked, so the flash-all is your best option. If you see the red exclamation point with the error android laying on his back, you press power and up volume and toggle that and it will bring in the stock recovery which you can sideload the OTA however it may fail since you have magisk.
I bought my phone stock last year and have not rooted it or modified it in anyway. Too many problems and it only gets harder and harder as Google releases a new phone.
@mikeprius -- thank you for replying. after reading more on here, it seems like that's the way to go -- flash-all script, seems like i don't really need to do 1&2 that i wrote above as the flash-all will wipe that out by itself.
at that point i should be running the latest stock 8.1 but with an unlocked bootloader (and according boot up message screen) and i should be able to re-do the fastbook unlocking command to lock the phone back up.
(and yes, after reading even more now -- and i tried this yesterday -- i completely missed the portion about PWR + Vol Up button, that's why i think i had that issue, but still, i was able to push the update by pushing img and then the zip through).

If I were in your situation and the bootloader is unlocked, just use flash-all which has a wipe script then call it a day. I think trying to screw around even more is just a waste of time and I wouldn't even bother with the OTA, just erase and flash stock. You don't have to relock your bootloader if you don't want to, if you stay fully stock you may still be able to get OTA updates. I'm not sure if a bootloader locked is required someone can chime in as it has been awhile since I've done this, but over 1 yr ago, I just kept the bootloader unlocked, kept things stock and everything was good to go. Obviously there are security issues with an unlocked bootloader, but I'm sure you know this already
@mikeprius you keep saying reset/erase, do you suggest i re-set the phone and then flash the stock image?
i was just going to flash the stock image, i figured it already wipes the phone, and locking the bootloader would wipe it again, so what's the point of erasing all data prior?
Not to hijack this thread, but a question to add... I thought that there were kernels that would mask certain things to allow all of those apps to work, and get rid of the "problem with device" message.
Is that correct?

Just flash the stock images. It will auto reset.
Again, don't mess with anything just flash stock images, then go from there.
Also flash the newest version of the stock images out there. The pixel 2 will error if you try to downgrade any version.
here are all the steps to UNROOT and LOCK the boot loader on your Pixel 2 on a Mac (windblows users simply ignore all the "./" references).
1) download the latest ADB tools from google
2) download the latest factory Walleye image
3) unzip files from 1&2 into a common directory
4) edit flash-all.sh file and add "./" infront of every instance of "fastboot" in the script [windows users ignore this step]
5)hook up your phone to your computer in debug and file transfer mode. check that "./adb devices" loads your devide
6)type " ./adb reboot bootloader"
7) check that your device is still connected by typing "./fastboot devices"
8) type "./flash-all.sh"
===the script will run and your phone will be restored to stock, and UNROOTED. upon boot up skip through all of the setup steps and get to the phone settings as fast as you can. enable developer option, enable debug mode, set phone to data transfer ====
9) check that your phone is connect to your computer by "./adb devices"
10) type "./adb reboot bootloader"
11) check your devices is still connected by "./fastboot devices"
12) type "./fastboot flashing lock"
===== this will re-wipe your device again, you'll see the circle of death, and this will LOCK your boot loader back up again======
side note, feel free to skip over the steps where you check that your phone is still connected to the computer (./fastboot devices) if you're less paranoid and comfortable.

hey there. what is the command suppose to look like? every combination I try gives me an error:
first, I don't even enter the Fastboot command the same wayit given me an error:
Asads-MacBook:~ asad$ ./fastboot devices
-bash: ./fastboot: No such file or directory
so I try this: Asads-MacBook:~ asad$ fastboot devices
[serial #] fastboot
these are all the errors I get:
Asads-MacBook:~ asad$ cd /Users/asad/Desktop/walleye-opm1.171019.021
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: ./fastboot: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
fastboot: usage: unknown command ./flash
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
how is the command suppose to look that I can edit it the right way?
"fastboot: No such file or directory" means that you didn't do step 1, step 3 on the file you didn't download, and there should probably be a "cd /<whatever the 'common directory'>" is. (I just created a directory named adb. That's good enough for me to know what it's for.)
You have to download adb and fastboot (which come in the adb tools file), unzip them to whatever directory you're going to use for flashing the phone, and cd to that directory.
Then, since you're evidently on MacOS, each command has to have ./ in front of it (that says "the current directory"). Try all that, then see what happens.

yayy! that worked!
so i had adb and fastboot in a folder (platform-tools) and i had the factory image in its own seperate folder (walleye-files). i was making the cd; walleye folder and trying to flash-all.sh there.
so i had to put the files from the walleye folder into the platform-tools folder. Then I made platform-tools the cd. now when . i could now follow all the steps from 4-12 and got the pixel 2 the way it was OTB.
thanks!
Great! I'm not a Mac expert (last time I used one was the 128K Mac in 1985), so I'm not sure how to export a path in MacOs, so I gave you the complicated way, but you got it done anyway. (If you ever find out how to add the platform-tools folder to your path, you can leave adb and fastboot in there and keep the ROMs [walleye] in their own folder, cd to it and adb and fastboot will still work.)

[GUIDE] [SUPPORT] How to root, optimize, and repair Xiaomi Redmi Go.

The One-for-All Guide to rooting, improving, and fixing various errors in Xiaomi Redmi Go!​Hello everyone! This thread that I made is for all people who wants to modify and gain full access, as well as to repair their Xiaomi Redmi Go devices the well-guided way, I've noticed that nobody has made an all-in-one guide for this phone so I decided to do it, this thread will keep on expanding depending on what I will discover about this phone, but for now, here is the thread, i expect that you have at least a little amount of knowledge when it comes to phones such as ADB and Developer Options.
What can we do with Xiaomi Redmi Go:
1. We can root it, and the best root manager for this phone is Magisk, SuperSU is also good, but if you're planning to use your phone for mobile banking, then Magisk is right for you. (Unfortunately this isn't true right now due to ctsProfile being hard to manipulate, Redmi Go supports hardware backed key attestation which means your device will definitely be not certified no matter what you do, so until we get a new method, don't root your phone if you want to use apps like Google Pay
2. TWRP is the current custom recovery available for this phone, it has flaws, but its currently the best out there, so its worth the shot to install it, the thread for it will guide you.
3. No custom kernels, people said that they have managed to install AOSP 9 and GSI on this device and made it boot up, but for me, it's better to wait for the official ROM update, after all, the device is still supported.
Prerequisites:
1. Xiaomi Redmi Go
2. An internet connection, a strong one is recommended if you want to download a ROM.
3. A computer with SDK Platform Tools ready to use, this is required, the link is here: https://developer.android.com/studio/releases/platform-tools
Don't forget to also get its driver! The link is also here: https://developer.android.com/studio/run/win-usb
The drivers are tricky to install but I will guide you on doing it in the easiest way possible, please continue on the thread.
4. SD card, your user data will be erased later, better back your files up, this is a warning.
5. Turning on "OEM unlocking" and USB Debugging in Developer Options, this is also really important!
Table of contents:
1. Unlocking the bootloader (and setting up ADB)
2. Rooting
3. Applying the custom recovery
4. Additional modifications
5. Stock ROM links
6. Bonus Section
WARNING: I am not responsible for anything that happens to your device as you follow my guide, do not blame me if you turned your device into a paperweight, made it explode, made it fly or whatever it may be, you chose to modify this phone and you should be accountable for it, you must know the consequences of what you're doing, try to point your finger at me because of what YOU did and I will laugh at you.
I am ready to assist though, so please feel free to ask some questions!
Let us begin, this will take several minutes, so please be patient and avoid rushing.
1. Unlocking the bootloader.
NOTE: This requires your computer to have SDK Platform Tools extracted to any location as long as its easy to access, and its really complicated to talk about it here, this step doesn't include the method where you request a code from Xiaomi, but I've provided a link for it.
A. First, get your phone up, and open the folder on where the SDK Platform Tools are placed, make sure that your in the directory where you see the .exe files of the SDK, now, hold Shift on the keyboard and click "Open Command Prompt here" and type "adb reboot bootloader", without quotes don't forget! This applies to all the steps that I will provide, don't forget to change the USB connection mode of your phone to PTP for it to be detected by ADB! (Only applies to Windows 8/8.1) Once your phone is asking for an authorization, check "Always allow this computer" then tap allow.
B. Once your device has been booted up into Fastboot or the bootloader, check first if your device is being detected, type "fastboot devices", if yes then proceed, if no, then stop here for now.
1B. If this happens then you may have to check your drivers and see if its installed correctly, once your device can be seen at "adb devices" it should also been seen in "fastboot devices" and when the phone is in adb sideload, if not then you have to reinstall ADB, get the proper drivers and do it again.
C. Now, type "fastboot oem unlock-go", the terminal will warn you that all of your user data will be removed, if you have them backed up then and go ahead and enter the command, if not, then just type "fastboot reboot" and start backing up your files, then do this again.
D. The phone will boot up and say "Erasing", to confirm that your phone has its bootloader unlocked, once it boots up again see if it says "Unlocked" on the bottom part of your screen, if there is then congratulations, it should be unlocked at this point.
1D. https://www.getdroidtips.com/unlock-bootloader-xiaomi-redmi-go/, this one particular link provides you on how to unlock the bootloader by entering a certain code, I believe this is a safer method but requires a bit of time, go here if you're interested.
NOTE: The phone supports the command "fastboot flashing unlock_critical" if you are going to unlock your phone with the normal command (fastboot oem unlock_go/fastboot flashing unlock), consider using this 2nd command too, what it does is that it allows you to also flash partitions you supposedly don't have access to, just be very careful not to flash any wrong file! It will be useful to make the "flash_all.bat" script work that you can find on the fastboot ROM for this device, more below!
Once your bootloader has been unlocked, you can now proceed to the other steps that I provided here, don't forget to enable USB Debugging on your Developer Options.
1.2 Setting up ADB
1. Grab your phone, unlock and open your Developer Options then enable "USB Debugging", then change your connection type to "PTP" if you are using Windows 8/8.1, I am not sure if this is required on 7, but it is not needed on Windows 10.
2. Go to this link: https://developer.android.com/studio/releases/platform-tools and download the .zip file, then extract it to a location that is easy to access, like your desktop.
3. Get the official Google drivers here: https://developer.android.com/studio/run/win-usb download the .zip file as well, and extract it too.
4. Go to the extracted folder of your SDK Platform Tools, and go to the directory where you can see various .exe files such as "adb.exe", now, hold the Shift key then click the Right mouse button, then click "Open command prompt here" If this doesn't work for you, open up CMD with admin rights, then type in cd *the location of your platform tools* say on mine, I will input cd C:\Users\James\Downloads\platform-tools_r31.0.3-windows\platform-tools then enter
5. Open your Device Manager by pressing Windows + R, put "devmgmt.msc" without any quotes then Enter, do not close the Device Manager until you're done with all the steps! And please be fast here too or else ADB will not work, now go to your extracted folder of the Google USB driver, and look for the file "android_winusb.inf", copy the location path of it as you will need the exact location path of the file later, in my case it was "C:\Users\Symphony\Desktop\latest_usb_driver_windows\usb_driver\android_winusb.inf".
4A. There are 3 main ADB devices that you have to install, Android ADB Interface, Android Bootloader Interface and Android Composite ADB Interface, so I will divide this into 3 sections, have your Device Manager, and the exact location of the .inf.
NOTE: Turn off the internet connection of your computer, why? Because, if you let Windows install the drivers for you, the drivers may be incorrect and will break things apart, as we will encounter several "Unknown devices" in the Device Manager and we have to update them with the extracted files from Google.
Android ADB Interface
1. Now, make sure that USB Debugging is enabled, now plug in your phone and let the drivers install WHILE your computer is offline, now go to your Device Manager after the driver installation and you should see that there is a driver named "Android" with an exclamation mark.
2. Select the "Android" driver with an exclamation mark, then click "Update device driver", click "Browse my computer for driver software" then click "Let me pick from the list of devices on my computer", click Next, then click "Have Disk", now, remember the location path you copied earlier? Now paste that path (like C:\Users\Symphony\Desktop\latest_usb_driver_windows\usb_driver\) to the white bar under "Copy manufacturers files from:", overwrite the A:\ with your copied path then Browse, select the "android_winusb.inf" and click OK, now, select the "Android ADB Interface", once the driver has been installed and the interface doesn't give errors such as "The device cannot start", then you're good to go.
NOTE: If you plug your phone and there is no "Android" device with exclamation mark, you can proceed to try and see if adb detects your device by typing "adb devices" in the command right now, it should be since this is what I experienced when setting up my device in Windows 10, this step usually applies only if you are using Windows 8/8.1
Android Bootloader Interface
1. To test, go to the command prompt you opened earlier, and type "adb devices", the device should now be detected at this point, when it does, type "adb reboot bootloader".
2. Now, make sure USB Debugging is enabled on the device before booting it into bootloader, now plug in your phone again and let the drivers install WHILE your computer is offline, Go to your Device Manager after the driver installation and you should see that there is a driver named "Android" with an exclamation mark.
3. Select the "Android" driver with an exclamation mark, then click "Update device driver", click "Browse my computer for driver software" then click "Let me pick from the list of devices on my computer", click Next, then click "Have Disk", now, remember the location path you copied earlier? Now paste that path (like C:\Users\Symphony\Desktop\latest_usb_driver_windows\usb_driver\) to the white bar under "Copy manufacturers files from:", overwrite the A:\ with your copied path then Browse, select the "android_winusb.inf" and click OK, now, select the "Android Bootloader Interface", once the driver has been installed and the interface doesn't give errors such as "The device cannot start", then you're good to go.
Android Composite ADB Interface
1. Before proceeding, type "fastboot devices", the device should now also be detected on fastboot, now, type "fastboot reboot", and afterwards, enable "USB Debugging" on the Developer Options, then go your command prompt, then type "adb reboot recovery".
2. Now, now plug in your phone again and let the drivers install WHILE your computer is offline, now go to your Device Manager after the driver installation and you should see that there is a driver named "Android" with an exclamation mark.
3. Select the "Android" driver with an exclamation mark, then click "Update device driver", click "Browse my computer for driver software" then click "Let me pick from the list of devices on my computer", click Next, then click "Have Disk", now, remember the location path you copied earlier? Now paste that path (like C:\Users\Symphony\Desktop\latest_usb_driver_windows\usb_driver\) to the white bar under "Copy manufacturers files from:", overwrite the A:\ with your copied path then Browse, select the "android_winusb.inf" and click OK, now, select the "Android Composite ADB Interface", once the driver has been installed and the interface doesn't give errors such as "The device cannot start", then you're good to go.
2. Applying the recovery/custom recovery
A. Open up your phone and ensure that USB Debugging has been enabled, now, open up your command prompt just like in Step 1 in Unlocking the Bootloader and type "adb reboot bootloader"
B. Next up, type "fastboot flash recovery path/to/recovery.img", substitute the path/to/ with the actual location of your recovery, and please make sure that the name of the image is "recovery.img"! Or else it will not overwrite/update the recovery, you can also put your recovery.img directly within the platform-tools folder so that all you have to type is "fastboot flash recovery recovery.img" then press enter.
C. Once your done, reboot the phone and press Volume Up + Power at the same time, and the recovery will start. (You may want to do this else the recovery will be automatically removed and replaced with the stock one)
1C. For the stock recovery, once you press the combination, the phone will say "No command", at this point, hold your Power button and press Volume up one time to get into recovery.
https://forum.xda-developers.com/android/development/recovery-twrp-3-3-0-redmi-t3929282 here is the link of the TWRP recovery, I encourage you to follow the steps mentioned in the post properly.
WARNING: The fix I provided below is now pushed here for 1 certain reason, before you try to root your phone and do everything else, you must decrypt your internal storage first and it is quite easy, first you must get the decrypt.zip linked in this thread (if the .zip cannot be found, I still have a copy of it), go to TWRP and do "format data", not Wipe Data! How so? Once you reboot to TWRP, it will show you the "Wipe" button, tap that, then the "Format Data" button should show up, this will require you to type in "yes" so type it in, then once it is done formatting, go back to the main TWRP screen, tap "Reboot", then "Reboot to Recovery", afterwards you must go to "Install" then proceed to install the "decrypt.zip", after that you can now flash .zip files from your internal storage too, but beware that you must do this every time you update your device!
3. Rooting your phone
A. To get started, install TWRP for your phone first.
B. Get the .zip file of Magisk/SuperSU so you can install them, the links are https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 and https://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703
C. Reboot your phone to recovery or just plug it in, open the command prompt again just like in the previous step and put "adb reboot recovery" without quotes.
D. Tap "Install" on your TWRP recovery and select the respective installation .zip file of your chosen root management app, and wait for it to finish.
1D. The .zip for both SuperSU and Magisk can be installed through "adb sideload", if incase you don't have an SD card! It may also work with fastboot as well but I need someone to confirm this.
E. When it's done, wipe the cache first, then reboot.
1E. If the root management app didn't appear in your phone after boot, just install the APK of it in the Play Store and check if root has been applied, if not, repeat step C and D again.
BONUS: It may be useful also to grab EdXposed or LSposed for Magisk and the link is here: https://forum.xda-developers.com/t/...or-of-xposed-oreo-pie-q-r-2020-07-19.4070199/ and here: https://forum.xda-developers.com/t/...e-magisk-module-edxposed-alternative.4228973/, please choose only one! You will use the normal Xposed if you're using a different root management app such as SuperSU, the link is here: https://forum.xda-developers.com/showthread.php?t=3034811
What this does is that if the app is an Xposed/EdXposed/LSposed framework module, any modifications it does to your phone will be based on memory only, it won't modify your phone directly which means your device will be clean, and if it incase the said modification bricks your phone, you can easily recover from it too!
BONUS 2: I also recommend getting the Busybox module from Magisk itself, it can easily be downloaded from the Magisk app, you will need this module if you want your root applications to work more efficiently and avoid errors, as most of them requires Busybox to work, don't use the Busybox installer apps on Play Store as they modify /system directly, only use it if you are using SuperSU.
4. Additional modifications
Once you've managed to root your phone and everything else, what I recommend you could do with your device is to get the following apps:
Titanium Backup - It has the ability to back up apps on your phone, and even its data! this app could do so much more than with what I just mentioned.
LSpeed - A root boosting app that has almost every root tweak packed into it, its really convenient to use! I do not recommend using Entropy tweaks as I heard it is a placebo.
Greenify - For me, this is the only legit battery saving app aside from LSpeed which also offers tons of battery saving features, it requires Xposed to have more options you have to buy it to gain full functionality
ROM Toolbox - This app pretty much contains everything a rooted user needs, such as a terminal and root-based file manager.
System app uninstaller (optional) - Just in case if you're planning to remove some bloatware (the list of it is below)
Root Browser - An alternative to ROM Toolbox, this root explorer is really popular and gets the job done without any interruptions.
Terminal emulator - This will allow you to enter various commands on your phone, like being able to reboot the phone without using any keys.
In order to make the phone as fluid as possible, just leave it with stock ROM installed, try to also use lite apps like Facebook Lite to reduce RAM and battery consumption.
Kernel Adiutor - Another great root application, it's like LSpeed but it doesn't automate tweaks, it instead allows you to modify most of it on your own, then it reapplies your tweaks every time your cellphone will boot up if you tap the "Apply on startup" switch. the link for the app is here: https://m.apkpure.com/kernel-adiutor-root/com.grarak.kerneladiutor
NOTE: Most of these apps can be found on the Play Store, and please don't install any more similar root boosting apps such as HEBF, scripts such as V6 Supercharger, or modifying files like build.prop, it is due to the fact that this will conflict with LSpeed, as LSpeed contains most of the tweaks that past scripts and apps provide, this will result in your phone slowing down a lot, Greenify will require Xposed Framework which is mentioned above on the Rooting section, the link to LSpeed is here https://github.com/Paget96/LSpeed, because the app has been removed from Play Store.
WARNING: The perf.zip https://forum.xda-developers.com/android/development/-t3935220 here, that was provided in Xiaomi Redmi Go forum section must be applied with extreme caution, you have to make a backup of your build.prop in /system, and build.prop + default.prop in /vendor for easy recovery, you can use ZipMe to easily make a backup for these files.
5. Stock ROM links
https://xiaomirom.com/en/rom/redmi-go-tiare-global-fastboot-recovery-rom/, this link so far provides all the ROMs (both recovery and fastboot) available for download on this phone, and they are actually light enough, so it will be easy to download them.
https://xiaomifirmwareupdater.com/archive/miui/tiare/ a new link I've found recently, this rom contains the .tgz format of the latest ROM for the Xiaomi Redmi Go, which could be used for fastboot and Mi Flash Tool, just search for the model and go for Global.
NOTE: Most of the ROMs for this phone provided on several sites, even on the actual Xiaomi website, has an invalid format of .zip, and doesn't contain a flashall script, as a result, Mi Flash Tool will never be able to use these ROMs, you could not also use adb sideload and fastboot for these ROMs, only the stock recovery of the phone could install the ROM, due to the links provided above finally giving the latest ROM versions for the phone, extracting the stock recovery is very easy now, you can do it yourself but if you need a link, tell me.
5A. Applying the stock ROM
This section will be divided into 2 sections, flashing the ROM through recovery, flashing the ROM through fastboot manually, or automatically with flash_all.bat
Stock recovery method.
A. Download the stock ROM with .zip format and put it into your SD Card.
B. Flash your recovery back to stock with the steps given above, boot into your stock recovery, then using your Power button and volume keys to navigate, select "Apply update from SD card".
C. Select the .zip file and wait for the update to finish.
D. The device will boot up automatically after, if not, just go back to the main menu of the recovery and select "Reboot system", enjoy!
Fastboot manual flashing method.
A. Ensure that you have prepared your device and computer for ADB, now grab the ROM given in this thread in .tgz format, and keep extracting the file until you see the files such as "flash-all.sh" after extraction, as you need to extract the .tgz ROM two times before you could use it properly.
B. Now go to the extracted folder of the stock ROM, go the "images" folder and copy the following image files: boot.img, system.img, recovery.img (make a backup of this file somewhere!), vendor.img, cache.img, userdata.img, persist.img, and splash.img.
C. Paste them to the extracted folder of your SDK Platform Tools where various .exe files are located such as "adb.exe", or in my case the location is "C:\Users\Symphony\Downloads\platform-tools_r29.0.4-windows\platform-tools".
D. Now open your command prompt on this directory, or Shift + Right click, then plug in your phone, now type "adb reboot bootloader" so your phone will go to bootloader, don't forget to enable "USB Debugging" and PTP connection mode before rebooting! (only applies to Windows 8/8.1, it may vary on Windows 7 but it is different on 10, no need for PTP connection mode, you can just turn on USB debugging and that's all)
E. Now, this is a little tricky, but try to follow me as much as you can, make sure first that you are detected with "fastboot devices", input the following commands that I will give so you can flash the ROM to your phone, now go to the command prompt and:
To flash the boot.img to your phone, put the command: "fastboot flash boot boot.img"
For the recovery, the command is: "fastboot flash recovery recovery.img"
For the system or main OS: "fastboot flash system system.img"
For cache: "fastboot flash cache cache.img"
For persist: "fastboot flash persist persist.img"
For the vendor or additional system files: "fastboot flash vendor vendor.img"
For data or apps: "fastboot flash userdata userdata.img"
For splash or probably boot animation: "fastboot flash splash splash.img"
D. After that, type "fastboot reboot", and enjoy!
Fastboot automatic flashing method (NEW!)
A. Extract the fastboot ROM 2 times as instructed, after getting the files, grab all the files and copy it to the directory of your platform tools where files such as "adb.exe" can be found, just copy all the files in there and that's all you have to do.
B. Open the "flash_all.bat" on Notepad and remove the following lines:
fastboot %* getvar product 2>&1 | findstr /r /c:"^product: *tiare" || echo Missmatching image and device
fastboot %* getvar product 2>&1 | findstr /r /c:"^product: *tiare" || exit /B 1
Afterwards, save the .bat file, that should be ready to use now
C. As instructed above, you must also do "fastboot flashing unlock_critical" after unlocking your bootloader the normal way, this will act as your 2nd unlock command, without this, the flash_all.bat will not work as it should be.
D. Boot up your phone in fastboot mode, open up your adb devices and make sure that your phone is seen in "fastboot devices", once it does, type in "flash_all.bat" without any quotes and execute it, the command will now automatically flash everything without you doing anything else, it will also automatically reboot after doing so.
Bonus section:
1. TWRP-compatible stock ROM
For this part, in order for you to generate a TWRP-flashable stock ROM is by basically making it yourself, you have to make sure that your patch is latest, and its pretty much a good idea to just tick everything in the backup selection except for the recovery, as well as the cache as you don't need those.
Once you have it, go ahead and keep it somewhere safe but easy to find, so if case that you need to use it, you could get it immediately, this is extremely useful so please just do it, as of now, I've confirmed that only the /data backup was usable, but please try to confirm if other partition backups are working for you.
Certain custom ROMs that can boot up in this device could be flashed through TWRP though, and the links of them are provided here in this thread.
2. GSI, AOSP 9 and custom ROMs
The link for AOSP is provided here: https://forum.xda-developers.com/android/development/redmi-aosp-9-t3922192
The link for GSI is right here: https://forum.xda-developers.com/android/general/tested-gsi-redmi-t3924705
These images/ROMs can be applied with TWRP, just make sure to follow the steps mentioned in these posts to avoid inconvenience, don't forget to take precautions too! I haven't tried them, but so far I believe that these are stable to use.
There are also custom ROMs released for the device but I am lazy to link all of them, they can easily be found by going here: https://forum.xda-developers.com/tags/xiaomi-redmi-go/
Please take note that I haven't tested these custom ROMs yet and I most likely never will, since the stock ROM for the device is already good enough, you can comment here and tell me what custom ROMs are stable so I can link them here for future reference.
3. Current status
My phone is still working, yes! and it's still staying strong, updated to 2.25 using the fastboot method and it is still fast, the only issue currently is that SafetyNet is a lot more secure than before, so it will be impossible to use stuff like Google Pay for now.
I usually decided to lay low and just stay with my LSpeed, Kernel Adiutor and Greenify, all I had to do is to tinker with these apps and my phone just reached into a whole new level! The performance improvement is nice, that I didn't need to use a custom ROM anymore.
4. How to install a OTA update after rooting your device
Due to the changes made by Google on SafetyNet, and the fact that this device will always require you to wipe the device every update, it is pretty much the same, it doesn't matter anymore if you are certified or not, you will still receive an OTA update even if your device is not certified as long as you are using the stock ROM, you only won't be able to install it, and if you want to install the OTA update you must install it by flashing the updated fastboot ROM, I have links for it above, you can try installing the OTA updates yourself through the settings but you will still have to do a factory reset anyway, you have to also unroot also and revert to stock recovery, else the installation will fail, and your device may slower afterwards.
5. Bloatware you can safely remove (NEW!)
So, like I said above, as much as how lightweight the device is, there are still bloatware that you can remove if you really want, but it's only 3 of them:
Mi Video
Mint Browser
Mi Music
The rest such as Mi Share and Mint Launcher are also bloatware, you can remove them but to me they are useful so I didn't, do not remove the "Cleaner" app, if it however says something like "com.CleanMaster", you can try removing it but take caution as your Play Store may be removed along with it too.
Credits to everyone who made the apps/tools that I mentioned here! such as @topjohnwu for the Magisk, and @YasiR Siddiqui for the TWRP, @Paget96 for the awesome LSpeed app, @rovo89 for the Xposed Framework and many more, you guys totally rock!
Hello and thank you for this tutorial. I'd like to ask. Do You know a way where I can unlock the bootloader without permissions or oem unlock? I have a soft-bricked device and for me, there is no way I can get into the OS and manually switch the Oem unlock setting. I've tried different softwares, different adb commands, different region firmwares, still no luck. I can't also get into the the download mode. I mean, yeah, I get the "no command" screen but after pressing power button + up volume button my phone restarts into the fastboot mode and there is no way I can normally boot. It's looping to fastboot mode over and over...

Can you please elaborate all of what you've done so far? I will also ask you a few questions.
1. Is your phone usable with the platform tools? I mean with adb and such.
2. Did you try going into recovery and flashing stock ROM through there?
3. Is your phone being detected by "fastboot devices"? The fastboot mode of Redmi Go is its download mode, and i've provided the link for the stock ROM that's usable thru fastboot mode, as well as on how to apply it.
My phone is usable with adb and such, the recovery mode was not working, only the fastboot. I've tried flashing stock rom with the flash tool but I had no success with a bricked soft and a locked bootloader. I've finally fixed it by going into the edl mode by test point method then I flashed the stock rom, and I've fixed my problem this way. I couldn't unlock the bootloader manually from adb or the unlocker tool, but I've did it in the edl way.

Can you please elaborate the term "edl mode"?
Good job then, usually, before you modify the phone and start doing something crazy out of stock, your number one step is to really unlock the bootloader, and in order to make things more easier, you should allow your OEM to be unlocked through the developer options, after that you can now unlock the bootloader with fastboot.

Yes, it's the emergency download mode. You use it when there is nothing you can do about the soft of your device. It automatically unlock the bootloader and you can flash the stock rom. Well, my problem was another. I did not tried to flash roms or recoveries with a locked bl. My phone automatically rebooted into the fastboot mode and from there I was not able to start my phone normally. I've tried rebooting fastboot from adb, unlock bl from adb, no success. I had to dissamembly the phone and make a short-circuit to the test points while slowly pushing in the mtp cable with the battery disconnected. Once I saw the Qualcomm driver on device manager I was able to flash the stock rom. You can search if you want to, for the test pins of this device. Btw, thank for your advice, you are really helpful to the community! ?

Woah, you really had to open the phone before doing it, that's an interesting method!
That part where your phone booted into fastboot was kind of scary, any ideas why it booted into fastboot in the first place? It has to be reported if incase, seems like a dangerous bug.

I'm not really sure if a malware caused this issue or a failed system update over-night.

I usually had failed system updates numerous times because when i install them, the phone has already been modified by a lot, and that's actually riskier.
That's why i recommend unrooting and putting back the stock recovery before updating first, still works on mine even with "Device is not certified" by Play Store.

In the setting up ADB step, I don't clearly understand. When I connect my device to the pc, no drivers are installing. And there is no driver named "Android" with an exclamation mark. But my device is getting recognized in "portable devices >> redmi go". I'm very new with adb it would be a lot of help.

Yeah, I've done everything you told, I also turned the connection mode to PTP also. Somehow it just not showing that android with an exclamation mark.
after that, I even tried to use the 15-second ADB installer. after installing that I tried to flash recovery but that just didn't do anything. After using that flashing command, I had the same stock recovery.
I'm really thankful you took the time to answer my question.
Help!! My device stuck on screen saying your system has been destroyed. What I had done is locked the bootloader using command fastboot oem lock then this happened. Now i can boot device in stock recovery and bootloader too but when i am trying to unlock bootloader it says device is lock and also i am not able to flash anything. Plz help.
I am not able to flash TWRP on my redmi go
How to update the redmi go to the latest version without formatting/Factory Reset should I just follow Fastboot flashing method and if so which files should I just flash. Thank you

Hi! sorry for the late reply, if this is the case then it's fine, you can just connect the device, open up adb tools, type adb devices and ensure that your USB debugging is on, and the device will connect immediately, at that point all you need is the adb driver for Fastboot

oh no, but why lock your bootloader? you can try using a recovery ROM, you must have a spare SD Card within you, grab a recovery ROM, put it in your sd card then put it into the phone and use it on stock recovery, you should be able to apply it and boot back into the system, please update me

Enable USB Debugging in Recovery Mode

Hi,
during the update the phone got stuck, daughter restarted couple of times but it always got to the 76%, hang there and then restarted itself in the endless loop.
I've tried the the hard reset (Power+VolUP) and it got to the screen saying "No Command". Then I pressed the same combo again to get to the bootloader and tried the wipe / reset. During that process I got the error message "E: Can't send SPI message. Try again" and then it said it was successful, but rebooting did nothing, got stuck in the restart loop.
So I've done the research and wanted to to upload the OTA update, have done that but that didn't do anything.
So I've found some articles on how to upload the stock rom/image but I'm unable to do so as sending adb commands is disabled due to the phone being LOCKED. I've learned that the USB debugging needs to be enabled, however I'm unable to get into the OS to set it up, so found this article:
How to enable USB Debugging in Android using recovery mode?
One million questions, Is it possible to Enable USB Debugging in Android Using Recovery Mode or any other technique? Well, the answer is Yes! It is now
www.isrgrajan.com
which outlines the following steps (in summary):
Download the Stock ROM for your device- Google it, I am dam sure you can find it. [DONE]
Download SuperSU from UPDATE-SuperSU-v1.65.zip [DONE][looks pretty old though]
Steps to Enable USB Debugging Using Recovery Mode
Unzip the stock ROM. [DONE]
Within the extracted folder, you will find the system.img well extract it too using Ext4 Unpacker [DONE but plenty of folder are empty, but eventually plentu of APK along]
Also, extract the Update-SuperSU.v1.65.zip file. [DONE, again, looks pretty old]
Now open the folder where you have extracted the system.img files [DONE]
Grab any .apk file from this folder and change the extension from .apk to .zip [PROBLEM: the apks are all over the shop. Which APK shall I pick up?]
And Copy the RSA Certificated to the Update-SuperSU.v1.65 folder (delete previous files if exist) [PROBLEM: unable to find any "RSA Certificated" like files once I open ANY apk]
Also, copy the build.prop to the system folder located within Update-SuperSU.v1.65 folder [BLOCKED by previous step]
Locate the update-script file within this folder and edit it using Notepad++ [BLOCKED by previous step]
You need to update the build.prop file after adding the following line at the bottom [BLOCKED by previous step]
persist.service.adb.enable=1
Next step is updating SQLite Database [WHERE would I do this step?]
Which can be done by adding the following code to the update-script file
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value=1 WHERE name='adb_enabled'"
What would I do then? How to actually apply the changes back to the phone?
Does anyone know of better / latest step by step process of enabling / unlocking the device or is my device now completely and unrepairably bricked?
Thank you.

For a while (since when, I don't know) persistent properties are not shared as individual files in /data/property.
They are all packed inside /data/property/persistent_properties.

I've tried the steps but I'm crashing on sending any commands to the device. While I'm in the recovery, I see the following details and options:
```
Android Recovery
google/blueline/blueline
12/SP1A.210812.016.B2/8602260
user/release-keys
Use volume up/down and power
Warning: Previous installation has failed. Your device may fail to boot if you reboot or power off now
- Reboot system now
- Reboot to bootloader
- Enter Fastboot
- Apply Update from ADB
- Apply update from SD card
- Wipe data/factory reset
- Mount /system
- View recovery logs
- Run Graphics Test
- Run Locale Test
- Power Off
```
where I run the adb command:
`adb shell mount data` I get the `adb.exe: no devices/emulators found`.
when I go to the `Apply update from ADB` and run the command above I get `error: closed`.
Basically I'm unable to run any adb commands as of the first message, and the only place I can it's from within the update. I've noticed that while in the 'Update via ADB', then in the Win Device Manager I can see that the driver is changed to `Android Composite ADB Interface` and only now it's accepting very limited commands. `adb devices` command generates: `<device id number>: sideload`.
When in the fastboot, it switches to `Android Bootloader Interface` in the DEvice manager.
When in recovery, the device is disconnected from the computer. (is not listed in the device manager)
any thoughts. thanks
Note: that phone was never rooted.

On my pixel3, /dev/block/dm-4 is mounted to /data. Try "adb shell mount /dev/block/dm-4 /data".
The instructions you are following are very old, and likely obsolete. SuperSu is also obsolete. Try to find a newer method.

the issue is I'm unable to run that command `adb shell mount...` with the `no devices/emulator found` message. I believe it's because the device is not even listed in the device manager (windows) when in recovery mode. When in the update mode, then it's listed in the DM. See my post above, I've updated it few times. Thanks
Btw on that link if you check the posts there are newer ones (1.5y back) claiming it works so might actually work
If you're unable to sideload the OTA via PC, I don't think there's any other option besides paying for a repair, or replacing the device. A locked bootloader definitely makes recovery a lot harder.

I've used the adb to upload the ota and that went, according the message ok, but the system won't start up. Device is recognized only when I choose the "Apply update from ADB" option in recovery mode. The moment I choose it, it shows up as a device in device manager and "adb devices" lists it ok. In fastboot mode it does list it in device manager, but "adb devices" doesn't list it.
It's the latest driver

If I understand correctly, you're using "adb devices" when in fastboot mode? You need to use "fastboot devices". If that works and lists the phone then you may be able to use the flash tool on the Google website

This requires OEM Unlocking to be enabled so it won't be much help here.
Rescue Mode might work though.
@vajnorcan try this:
Boot to bootloader and select Rescue Mode using the volume buttons, then press Power to enter it.
On your PC, go to pixelrepair.withgoogle.com and connect the USB cable to your device. Select your carrier or select "Other" if device is unlocked.
I don't know whether this will actually work...I haven't heard of anyone using this tool to successfully recover.

'fastboot devices' is reading the device, which is good. but trying the online flash tool fails due to the device being locked. :/

This requires OEM Unlocking to be enabled so it won't be much help here.
Rescue Mode might work though.
@vajnorcan try this:
Boot to bootloader and select Rescue Mode using the volume buttons, then press Power to enter it.
On your PC, go to pixelrepair.withgoogle.com and connect the USB cable to your device. Select your carrier or select "Other" if device is unlocked.
I don't know whether this will actually work...I haven't heard of anyone using this tool to successfully recover.

The google tool has found and connected to the device, but it ends up in an error (on the device) and saying "disconnected", looked promising, but not for long. thanks.
