with normal boot, i can access adb commands, its just that fastboot mode is blank and hence unable to access commands. Ive installed all possible drivers, i think the kernel is broken. Any possible way to fix this?

Is developer options and usb debugging enabled in your phones settings? Also no screen lock set? If so if you have another Android device that's also rooted with magisk you can use Osm0sis and Surge's fastboot/adb magisk module, (a quick search in magisk will pull it up) Install it on your other device and use an otg cable ($5 online or make one yourself) and using termux app from "other phone" with connected otg & magisk root type: su (hit enter) grant root once it pops up then type: adb reboot bootloader then tick the pop up on phone you are trying to boot recovery on when it pops up. Then type: fastboot boot twrp_3.4.0-9-11.img (hit enter) Just make sure you put your TWRP recovery.img in correct directory on phone you you're using termux app on with otg and fastboot/adb module to boot the phone you are trying to boot to recovery.
Using root explorer directory in termux is: /data/data/com.termux/files/home/
place your TWRP_3.4.0-9-11.img ,, which ever TWRP image you are trying to boot in that directory...
Hope this makes sense. I don't use Windows and haven't for many years now. I've unlocked bootloader's and rooted many devices using another Android device this way now for years. Super easy! Not sure why you would be getting a black screen. Have you searched for solution to this? I would definitely search , a lot about the black screen situation.. Make sure you have a charged battery too. Sounds stupid I know but it's possible you are at 0%.. Hope this helps...

[Q] Nexus s 4g locked up

Okay, first of all I know, I'm a total noob. I have followed these forums a long time and have successfully rooted a few phones. One of which was my nexus s 4g. I was trying to unroot the phone so I could get ics. This is when I ran into problems and right now I just want to be able to get my phone working again. Right now I am stuck on the Miui boot up screen and no matter how long I wait it stays on that screen. If I do a battery pull and hold down power and vol up I can get into the bootloader screen with the information as follows: fastboot mode, product name-Herring, HW Version Rev 34, Bootloader version-D720SPAKE1, Baseband version-D720SPAKE1, Carrier info, SPR, serial number-37308B81276A00EC, Lock State-locked. Then the different options I can choose are reboot bootloader, reboot, recovery, power off. If I choose reboot, it takes me back to the mius screen and stays there. If I choose recovery, I get the triangle with the exclamation point. I then hold power and up volume again and I get a screen that says Android system recovery <3e> with reboot system now, apply update from sd card wipe data/factory reset and wipe cache partition. I have tried all of these as well with no luck. When I go to apply update from sd card I get matrix-cfs_v15.5 zip, root.zip, update.zip and then what looks like apps such as Alarms/, Android/,MIUI?, etc. If I try to select any of the first ones such as matrix-cfs_v15.5 zip, I get Install /sdcard... , finding update package..., opening update package..., verifying update package..., E.signature verification failed, Installation aborted. Then it gives me the system recovery options again. Any help would be appreciated.
Did you try ADB fastboot method?
Not sure how to try that
I tried doing the adb, followed all directions and installed and when I go to the command prompt and type in anything, such as, adb reboot bootloader I get, adb is not recognized as an internal or external command, operable program or batch file.
ok I got that working now but when I type adb devices and press enter I get a message saying List of devices attached and then it doesn't show anything and I get the command prompt again saying:c:\android\android-sdk\platform-tools>
also since the phone is stuck in either the miui screen or bootloader I can't get into it to put it in usb debugging mode. I am trying on my own to get this going and am stuck any and all help would be very much appreciated.

I think that means you have a locked bootloader.
And from what you're telling, I believe you have stock recovery.
Also, when you're in fastboot mode, I don't think adb commands apply. Use fastboot commands instead (i.e. fastboot devices).
Search for guides showing you how to install and use fastboot.
I did fastboot as well and the problem I think I am having is it's not recognizing my phone because usb debugging wasn't turned on before it locked up. How would I get it to recognize my phone or download an img to my phone if it is not being recognized. Sorry if this is a stupid question.
You don't need usb debugging in fastboot mode.
You either:
1. Don't have drivers installed.
2. Don't have fastboot installed correctly.
You really need to read a guide or two, through and thoroughly.
Bc it sounds like you have no clues.
Yeah dude. Take a step back and go over what you have installed and where you installed it.Yes, fastboot commands start with fastboot instead of adb. And you're on stock recovery.
Thanks for the answer that I don't need usb debugging in fastboot mode, I wasn't sure of that. I have downloaded and installed my drivers multiple times and when I use the device manager to update drivers it says I have the latest drivers installed already. Whenever I do fastboot commands I will type in fastboot devices and shouldn't my device serial number come up? It just gives me the line c:\android\android-sdk\platform-tools>
And is waiting on me to type a command in. And yes I have been looking at guides all night. I appreciate any help you guys might have and remember we were all noobs at one time.
The zip in this tutorial should help.
It has adb, fastboot, and the drivers needed.
And unlock the bootloader because it is locked.
Finally got it, I had everything downloaded that I needed already, but looking at different forums, etc, it seemed like everyone named it something different. So I just used the one link you gave me and did it exactly the same way and it worked. Thanks so much! and again thanks for your patience.

[Solved] Authorize remote debugging on broken screen

I have a stock N5 that has a broken screen. You can see some parts of it but doesn't respond to touch at all. I saw there was an app on here that let's you see and remotely control the screen using your PC with adb. It looks like I might have the usb debugging turn on, however my adb shell is not authorized but does see the device. I have tried booting into stock recovery, but adb is not running at that time to allow me to push access keys.
What options do I have to be able to remotely use this phone. I want to use it as a camera for tinycam pro

If your bootloader is unlocked, you can boot TWRP without flashing anything. From TWRP you'll get adb access.
If your bootloader is locked, you're doomed. :-/
Bootloader is locked. Is there anything I can flash to get it to work.

I was able to use fastboot and unlock the bootloader. The phone restarted and went to a welcome screen. I was then able to flash twrp in recovery and load that up. I got into adb shell and ran some echo commands to put things into the default.props file in an attempt to enable us debugging when it rebooted. Well I guess the commands we're not correct or something but it didn't work. So then I went back into the bootloader and I thought I had to reflash twrp again, so I ran the same fastboot command I did before to load twrp. Says it wrote fine but now when I select recovery the phone just reboots back to the welcome screen. Since most of the screen is messed up o can't make out why that happens. Any help would be appreciated

In case anyone else has the similar problem, once back into TWRP by using 'fastboot boot <img>', i used this post to mount the file system under system2 folder - https://forum.xda-developers.com/showpost.php?p=63829295&postcount=27
I then pushed my adb key onto the device so when the OS boots back up, it would allow adb to connect
Code:
adb push C:\Users\<username>\.android\adbkey.pub /data/misc/adb/adb_keys

[UNOFFICIAL][DECRYPTION WORKS] TWRP 3.3.1 for UMIDIGI F1 [20191103]

Introduction
This is an UNOFFICIAL TWRP port for UMIDIGI F1 that works properly with encrypted /data partition in official ROM. I am aware that the UMIDIGI F1 already has TWRP built for it, but none of them seem to have decryption working properly. In fact, every single TWRP, even official ones, for any MT6771 device, seem to have non-functional decryption support. Through some digging I managed to fix decryption at least for UMIDIGI F1, so here is my version of TWRP for the device.
Known Bugs
- Screen may flash on the password-input UI. Anything else is fine though.
This TWRP has been tested with official ROM and my LineageOS 17 port (https://forum.xda-developers.com/android/development/unofficial-lineageos-17-0-umidigi-f1-t3997827) and it works fine.
This is UNTESTED on the F1 Play. ONLY TESTED on regular F1.
Why Bother
Because security matters. Using a cheap device should not mean giving up security, and more importantly, privacy.
Instructions
1. Unlock bootloader
2. Enable ADB debugging in system
3. Execute "adb reboot bootloader" while having your phone connected to PC
4. Execute "fastboot flash recovery <your_downloaded_recovery>.img"
5. Reboot phone while holding Volume Up + Power buttons
Note: The official ROM may overwrite the recovery, so you may need to re-flash the recovery if this behavior isn't prevented either by TWRP or manually.

I appreciate your sharing this. I have added "system_image emmc" to the fstab file, so I can flash and backup the system.img
This works good on my F1,
But I tried to make this decrypt work for my other phone with 6771(Bold N1), but couldn't find all same files added to recovery/root from stock firmware.

Those files are extracted from vendor.img, but it can be different on different devices, e.g. keymaster version might be different. Also you will need to patch them using `patchelf` to make them use `/sbin/linker64` instead of `/system/bin/linker64`

Cause i test it without changes , it reboot to system
I think because they have different kernels
I am unable to install twrp.
When I run the "fasthboot flash recovery" command, cmd aparace "waiting for de ice" and nothing happens on my phone ...
Am I doing something wrong?
no fastboot response
for some reason (most likely pilot error, lol) the phone doesn't show when I do "fastboot devices" - even though the F1's screen shows "fastboot mode" in very tiny letters on the bottom-left.
probably something stupid I'm doing wrong, will keep trying...

You can operate from adb/fastboot folder and device can stay on fastboot mode but if drivers were not properly installed then no connection with pc.
Try installing:
- https://androidmtk.com/download-15-seconds-adb-installer
- https://androidmtk.com/download-mtk-usb-all-drivers
- https://www.androidweblog.com/download-mediatek-usb-vcom-drivers/
Start the process from device on using adb commands to always allow access to the pc. I mean:
Code:
adb devices
and then if device is detected you will see a screen warning to "always allow...." then tap on yes; this suppress future conflicts, then
Code:
adb reboot bootloader
while on fastboot follow with
Code:
fastboot devices

adb was already working (is how I made the thing reboot to bootloader, and yes I did tell it to permanently accept the computer I'm using.
this is on linux, so the drivers shouldn't be a problem... although SMH I never put USB IDs into the udev rules. which is interesting, because regular adb already worked fine without it - I have had phones in the past that some did, some did not, require the computer to know about vendor/hardware ID.
(and I know that the adb USB IDs are usually different than the ID for fastboot, as well.)
like I said, pilot error lol. but thank you again for the reply!
I have done the following:
Enabled Developer Options
Enabled USB Debugging
Enabled OEM Unlocking
Unlocked the bootloader with:
Code:
adb reboot bootloader
fastboot flashing unlock
Rebooted and Enabled USB Debugging again.
Then after downloading your recovery
Code:
adb reboot bootloader
fastboot boot ~/Downloads/recovery.img
But nothing happened.
I rebooted and thought I would try flashing
Code:
adb reboot bootloader
fastboot flash recovery ~/Downloads/recovery.img
It just paused on the boot screen saying "Your device has been unlocked and can't be trusted".
If I reboot then try to go direct to recovery:
Code:
adb reboot recovery
I end up with the broken android screen and "No command"
What am I missing?

While in fastboot the first you should do is see if device is detected by pc with
Code:
fastboot devices
It looks like something is wrong with your path, I ever avoid path copying or moving the file/image to the adb/fastboot directory but anyway if you don´t want to do it you can copy the path from the bar where your recovery file is allocated, for example, if the file is in Downloads directory like it seems actually is, no matter what unit/drive you are in you can set an absolute value to avoid errors, look at this example: C:\Users\your_user\Downloads
If your device is detected then you can flash the recovery as you were trying to do it with
Code:
fastboot flash recovery recovery.img
and then you can reboot directly to it without need to reboot to system previously and this will prevent TWRP from being overwritten, with
Code:
fastboot boot recovery.img
hmm, so when I checked the udev rules, it already had one for MTK/mediatek - and the USB vendor is '08ed' in fastboot as well as in regular adb, so it wasn't a problem with udev/plugdev.
which I guess may mean the lunix generic android drivers for fastboot might be... "lacking" - I'll have to scrounge up a win7 laptop and try the recommended windows drivers.

I don't think it was anything to do with the path as it output the file transfer size.
I think it was a combination of the following:
I wasn't pressing the right combinations of buttons after flashing.
i.e. holding VOL UP and pressing POWER on the screen saying "Your device has been unlocked and can't be trusted".
Rebooting might (?) have been reverting the recovery.
I was originally trying this on the firmware that was shipped 2019012414 but after flashing 2019090418 with SPFlashTool I had more success.
I also able to reboot to recovery directly after flashing with fastboot with the following:
Code:
fastboot oem reboot-recovery
Whichever was the key I can now reboot to recovery from adb too.

Your twrp eliminates fingerprint authentication.
I discovered something interesting, your twrp only works on my device, no other twrp works, but when I install it, I lose my fingerprint, it doesn't work at all.
Simply put, I must choose between the fingerprint or the root.

Try to clean flash last vendor build with spflash tool. First boot need stock recovery.
You don't need custom recovery to achieve root.
Maybe give a try to SNwriter (I never needed it though and can't help here).
Both of those twrp are not sticking. I have flashed with spoken flash tool v5 1944 win and I fastboot cmd with the same results.
Thanks
Gracias for this master ?

How to root zenfone 7 ZS670KS

hello guys
how do i root this phone please.
none of the google searched guides seem to work.
1. i've unlocked the bootloader using the asus app
2. i have adb installed on my pc
3. i've enabled usb debug mode on phone and allowing installation unknown apps
4. i've installed magisk v23 by downloading from github and just installing the apk file normally
5. i've downloaded a 2.9gb zip file from asus for androind 11 firmware onto phone and pc (but its a zip file that extracts a bin file, no image file)
my problem seems to be i don't know how to CREATE AND PATCH an image file or install twrp and install image file that way.
Could someone help, there doesn't seem to be any guides for rooting in this phones forum.
Look in the twrp thread: https://forum.xda-developers.com/t/recovery-official-twrp-for-asus-zenfone-7-series.4161719/
after twrp you can flash the magisk.zip

i keep getting era waiting for device when i want to flash the phoben with twrp.
adb reboot bootloader (works and i enter the recovery menu start, bootloader, recovery, power off etc)
fastboot flash recovery_a twrp.img (when i type this cmd power shell just says waiting for device)
i have universal drivers installed and android sdk installed. not sure why it isn't recognising the phone?
When my phone is switched on normally, cmd recognises it, when i use adb devices. but as soon as i reboot into recovery mode using cmd "adb reboot bootloader" it stops recognising the phone on the list of devices using the cmd "adb devices"
so you don`t get an answer from your phone by "fastboot devices" ?
Have you tried another usb cable and or port?

no answer from phone when in fastboot mode.
but i do get a reply in cmd when phone is switched on normally.
I'll try with another cable, but if it responds to adb when in normal mode. doesn't it mean it's not a cable issue but a software driver issue?

seems when i do adb reboot bootloader it goes into what i thought was called fastboot. It even says fastboot.
but in that mode my phone isn't recognised by cmd when type adb devices, it doesn't come up.
it has 4 options reboot system now, botloader, enter recovery, reboot to bootloader, power off.
if i then select enter recovery. it enters a smaller text screen with lots of small blue writing. when inside that screen (recovery mode) cmd seems to recognise my device.
but it says it is unauthorized. this is in recovery mode.
i'm not sure why it says it is unauthorized. i've authorised my pc to control the phone through the fingerprint, when the message popped up.
but i can't push the twrp.img file through because of this.
since cmd doesn't seem to recognise phone in fastboot mode.
and cmd doesn't seem to have authorisation in recovery mode.
any ideas?
is it possible to root using adb sideload or install twrp using adb sideload?

Thats the right mode.
Does the phone at normal start show that the bootloader is unlocked?
Your debugging mode is turned on in developer settings?
A sideload isn`t possible I think.

yes, shows bootloader is unlocked when i start the phone.
usb debugging mode is turned on.
i think for some reason in fastboot mode the device driver is not recognised in windows. have googled seems it was a very old problem that happned on phones 6 years ago. nut i haven't found anything recent to solve same error.

flashing pixel 2 without usb debugging

Hey guys, I need help flashing my Google pixel 2. It was off for a couple of months and now when I am trying to start it, its not booting without putting it on charge and even then it only shows the battery icon then the google icon and restarts (So a bootloop). But when I press and hold the power button and volume down key, it goes in the fastboot mode ( the one where all device information is shown with an Android Logo) (Pic att).
If I select Download mode, it just shows operation denied and if I select recovery mode then it goes to bootloop again. Also as far as I remember when I last used the phone, the usb debugging was turned off so please suggest what to do from here.
If you have USB debugging disabled with OEM unlocking off there's not much you can do. That's why I usually suggest if you're going to relock your bootloader keep oem unlocking enabled so you can flash the factory image if you run into problems. this has saved me a few times.
try downloading the platform tools and usb driver and running the unlock command, what message do you get? The first command you want to run is ADB devices to make sure that your device appears in the list and the command prompt. second command to run is fastboot reboot bootloader , If your phone restarts back into bootloader then you know you have the driver and fastboot /ADB installed and working properly. then go to the Android developer page and find the proper unlock fast boot command I think there's a different one for the Pixel 2.

The first command you want to run is ADB devices to make sure that your device appears in the list and the command prompt. second command to run is fastboot reboot bootloader , If your phone restarts back into bootloader then you know you have the driver and fastboot /ADB installed and working properly. then go to the Android developer page and find the proper unlock fast boot command I think there's a different one for the Pixel 2.

Hey thanks for the update man. I know I should have kept atleast oem unlocking enabled. My fault.
Now I followed your instructions and the phone only shows under fastboot devices. But when I run ADB devices it comes as blank under list of devices attached. I still tried the fastboot reboot bootloader command but the phone just restarts with the battery charging icon flashing on screen and then going back into the fastboot mode. (pic of which I attached in the original post).
Any other ideas would be appreciated, else ill just take it to a service centre.

Mine shows blank also when running the devices command.
If you can run commands like "fastboot reboot bootloader" or "fastboot reboot recovery" etc and the device restarts, then platform-tools and driver is installed. I mean make sure you have the latest versions of both or else there's no point on going any further. An older version platform-tools will cause a bunch off issues so update that for sure.
what happens when you run any of these commands when your in the bootlaoder menu (where it says Fastboot and device state: locked) (after you've updated platform-tools, check the version by typing the command " fastboot --version" - 31.0.3 is the latest version)
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot oem unlock
If you can unlock your device, you can flash recovery/bootloader image and go from there. But it doesn't look good.

Hey man, Thanks for the update.
Unfortunately none of these commands are working and yes I have the latest platform tools and drivers installed. Attaching image of the same.

yeah, it means the oem unlocking option is disabled in developer options. damn.
can you try logging into recover menu at all so you can update both boot slots A/B with the ota using adb update option in the recovery menu.
What about running a few fastboot commands to delete userdata and even switch boot slots. that Fastboot screen will show what slot you are booted in (either a or b). try switching slots and booting then?
fastboot --set-active=a (if you are in Slot-B)
fastboot --set-active=b (if you are in Slot-A)
After swithing slots, hit restart device and as soon as you see the Google Logo, hold volume down. If you can boot into Android, enable oem unlocking as soon as you can, don't even connect to wifi or whatever. Or try accessing Recovery mode after switching slots. Main goal is to try to access recovery to update ota and/or access Android to enable oem unlocking.
have you looked on xda for other fastboot commands to try? There's a few Unbrick posts on the Pixel subs - worth a try?

Okay so I tried switching slots. Currently active slot is A but it again shows error that slot chage is not allowed in locked state. Well was worth a try.
I tried almost everything to get into recovery menu as per my knowledge but cant. It just restarts back into the fastboot state or goes into bootloop.
I did a bit of searching before creating this thread but didnt found anything. Ill try again and see if someone has something similar.

download the full factory image (not ota) and extract it, and move the radio and bootloader images into platform tools folder and try flashing? But don't think you can.
Also, maybe try installing Skipsoft and see what commands you can execute from there? https://skipsoft.net/download/unified-android-toolkit-v1-7-2/
it supports the Pixel 2.
Not sure how the op in that thread above fixed his Pixel 2 with Skipsoft tool. His Device state said Locked in his screenshot on his post.
Also try draining the battery and see if it will boot into Recovery Mode at all. And check the other Pixel threads (like Pixel 3 XL) there's a few unbrick posts there also.
edit--try these commands
fastboot erase system
fastboot erase data
fastboot erase cache

Not sure how those users in the thread flashed the bootloader image since I didn't think you could if the device state is locked, but worth a try.
