Problems rooting, adb etc.

Hello, I've tried rooting my Nexus 7 (2013) with LTE for like 5 hours now...
I've done every single thing in every single thread, and I still can't do ****.
I've tried the WugFresh root toolkit, but that did not work at all for me, I uninstalled and remove what they told me to do... But nothing worked, when I followed the WugFresh toolkit I lost usb mass storage... N7 did not appear at all on my computer, which it did, before I tried to screw with it...
I've tried doing it the manual way too, downloading all the drivers, uninstalling the other onces first.. But nothing... I could not even get the device listed in adb! I tried the full driver installation thing + automatic check if everything worked out, but the tablet would NOT run the script to reboot it into fastboot, and when I tried to restart the tablet into fastboot, and then continue to run the toolkit, it would start TWRP, the popup on my computer told me to flash something "!flashready", but I could not find it in the sdcard...
I unlocked the n7 manually, holding the volume button and power button down.
I know that was very bad written, but I'm a bit in a hurry. Anything I could do?

So the current condition of your device is that ADB is nonfunctional but you are able to temporarily boot into TWRP with fastboot - is this correct?

Yes, that is correct, temporarily, with the toolkit I mentioned. But I do not find the files that the toolkit tells me to flash

I'm not sure what this means. If you're using a toolkit, you're not doing it manually. Have you tried ADB and fastboot alone, without a toolkit? Is TWRP on your phone now? If so, you're done; just flash from recovery 1) a ROM for a custom ROM or 2) SuperSU.zip for just root.
If you don't have TWRP, does your Google boot screen has a locked icon at the bottom? If so: for ADB to work you need to have debugging turned on in your phone's developer settings. You don't need ADB though; just reboot into the bootloader by holding power and volume-down. Then type "fastboot devices" and see if anything shows up.
If it's an unlocked icon, just flash a recovery.img from fastboot.

Tried both manually with adb, and with WugFresh toolkit. I got WugFresh to run TWRP temporarily.

The toolkit is using the command
Code:
fastboot boot openrecovery-twrp-2.6.3.0-deb.img
to temporarily boot it over the stock recovery. Since you unlocked your bootloader manually, you can replace the stock recovery manually too using
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.0-deb.img

Fastboot is separate from ADB. Your fastboot is working if the toolkit is able to boot TWRP.
Code:
fastboot devices
is what you use while your device is in the bootloader.

Help I bricked my Oneplus 3

Hi, i played around with my new OP3, and i wanted to root it. Since i'm noob at rooting, it went wrong. (i did it with twrp)
So first it just went in to bootloop, then i was still able to get to rcovery and stuff, but i followed a guide to fix bootloop, and that ****ed it even more up. The guide i followedet told me to use "OnePlus3_Unbrick_Tool"
After using "OnePlus3_Unbrick_Tool", i now cant even go into recovery anymore, the only thing i can do is go to bootloader, but when i'm in bootloader now, it wont connect proberly, so that i can use "flash twrp", so that i can use twrp recovery.
Also when i try to boot it, it because of "OnePlus3_Unbrick_Tool" goes into something, where it says "md5 checksum failed", and then restarts and does it again and again.....
I hope it's not bricked forever, pls help ))

have you tried re-flashing the stock or twrp recovery with adb sideload command?
if not give it a shot, it might work.

And how do you say I do that? I have tried using the "tool all in one", where you han flash both stock and twrp, but it doesnt seem to do anything, when i press them (and the device is in bootloader)

Just boot into bootloader mode and through command prompt check if your phone is detected by typing fastboot devices. If its detected then you flash a new recovery again. Forget the toolkit, just look for instructions on how to install a custom recovery.

In fastboot mode, did you manage to find your device on the computer? On Linux this is "sudo fastboot devices", on Windows it should be roughly similar.

Hey!
I'm not the expert but I have played with my 1+3 enough to have some knowledge.
First of all, do not use "all in one tools", those do not put you in control.
Cool, so fastboot is detected, though you can't get into the recovery?
Step 1) make sure you have the latest version of "fastboot" and "adb" (Android Debug Bridge) and unlock the bootloader. This tread should be helpfull: http://forum.xda-developers.com/oneplus-3/how-to/oneplus-3-how-to-unlock-bootloader-t3398733
You need to do this, because otherwise we will not be able to proceed (i.e. the phone is to be 'unlocked' for what we are about to do).
Step 2) If you are ready than let's flash a new recovery (TWRP):
This is also step 2 in the thread mentioned above. Very important: "Once the flash has completed, Don't use the "Fastboot Reboot" Command Instead Unplug Your phone then Manually boot it into recovery by keeping Power + Volume Down button pressed."
So once you have flashed a new recovery using fastboot, than you should reboot your phone into the new recovery!
step 3)
Once in the new recovery (TWRP) go to advanced and to ADB sideload. Make sure your computer detects your device with the command "adb devices" and flash a new ROM. Just for simplicity use the official OOS 3.2.4.
This should do the trick. Before you go and try make sure you understand EVERYTHING I have written. Let me know if you have questions.

Thank you, but i have not enabled "allow oem unlocking" in the developer settings when the phone worked, so i get a error message "FAILED (remote: oem unloc is not allowed)
What to do to unlock it then?

Bro, download 3.2.4 oos rom zip file from official link. Its around 1.3 GB. Just connect ur OP3 to computer. It will detect as MTP device.Im my computer it was in the name of RAIN Transfer the zip file to internal storage. Wipe cache. And select install option in TWRP and select the zip file u pushed and flash it. Best of luck..

Hey i have the same problem but this fix does not work for me.
So I have the bootloader unlocked and I can enter the bootload and my computer detects my device which is nice.
when I flash twrp on my phone trough CMD it doesnt work, my PC tells me that everything is okay but my phone will not boot into twrp and instead it will give me weird errors.
---------- Post added at 03:31 PM ---------- Previous post was at 02:56 PM ----------
this fix worked for me,
On the screen when the phone failed to md5 checksum, you've got several partition failed right? in red text.
- download this : https://www.androidfilehost.com/?fid=24591000424942573
and then extract.
- download platform tools attached below. extract in the same folder with first file you've downloaded.
- Boot your phone to fastboot mode, plug your usb, make sure adb and fastboot driver are installed.
- on the folder, hold shift and right click, click open command here
- type fastboot devices
- make sure your serial number appear.
- now flash the img of the missing file according to the partition in red text on your ms5 checksum failed one by one.
- e.g. "fastboot flash boot_aging boot_aging.img.
- make sure you flash all the missing partition.
- type fastboot reboot.
this will boot you to oos 3.1.2.
unfortunately I couldn't extract the newest oos dat. data. but you could always take the OTA
goodluck mate. sorry for my english

Hmm bad try installing all op3 drivers and see whether phone is detected or not. I was in the same situation previously. Pushing zip through adp terminal is painful process. I got device offline first,after solving that i got service not recognized issue. For solving that usb debugging needs to be enabled i stuck in that step.

can you enter recovery trough fastboot mode? I.e. if you are in fastboot mode you van use the volume keys to select recovery.
100% sure you can't enter recovery?
you can try Fast and pro's option. let us know!

How to wipe android partitons while NO access to Fastboot? PLZ help

Hi,
I have a unique problem. I cant go into fastboot. Yes, fastboot on my OPT is not a opltion.
I cant instal TWRP. I can't wipe the OS to flash a new one.
My question is this:
Is there a way to wipe the partitions on a android phone via windows or something?
This problem is created by me. Somehow I flash OOS over CM (??)
So when my phone boots (bootloader is unlocked) I will see 2 boot sequences wich prevents me from accesing the fastboot menu.
The solution I see is this: Enter TWRP --> Wipe all but USB-OTG ...
Anyway, I hope there is a android Einstein here because I'm at a loss..
Feel free to ask any questions and pls help me!

If you are getting two boot screens, please confirm if this is what you see in your first boot screen:
some text which goes like "Your device cannot be trusted etc etc. fastboot oem lock something something"
If yes, press the volume buttons at this screen, which will take you to an "Options menu"
This will have options to power off, restart, recovery, fastboot, back to previous page.
use volume down buttons to move selection to fastboot and press power button to select fastboot.
This will take you to bootloader.
Alternatively:
Is the device getting identified by your computer when connected?
If yes, and if you have adb tools installed, try this command, after connecting to computer and selecting usb configuration as transfer files
adb devices
The result of this should show your device
then type:
adb reboot bootloader
This should take you to your bootloader screen.

Thank you for your replay.
I have done all of this and i do understand how this works.
I have adb drivers installed, my computer does reconizes my phone and everything works even the reboot to bootloader via CMD. (adb devices, it shows, etc)
When my phone then tries to access the bootloader, it will show those messeges " this devices cant be trusted etc etc." afther 5 seconds again I see the the android logo (with a few lines of static on the bottom) (( that clearly is not right )) but it will show me again the same message " this devices cant be trusted etc etc" ... then it will just show me the battery icon and power precentage (this if I choose to boot to bootloader) or else it starts normally..
Clearly the flashing of CM failed. And with a sideload to install OxygenOS I can use it.. But it does prevents me from accessing the fastboot mode..
So Is there an alternative way to install TWRP without using the fastboot mode? Or is there an other way i can try to wipe the partitions inc. the os?
From there I know what to do.

When you are in bootloader, you should use fastboot command instead of adb.
And first, try to flash TWRP using: fastboot flashing recovery "YOUR TWRP IMAGE". If it works, flash rom like normal.
If that doesn't work, use QPST.

Hello, I downloaded and installed android beta update https://gauss-componentotacostmanua...22/08/03/b5192ec34f094ad9bb76e5554cd69f89.zip from https://www.xda-developers.com/oneplus-7-7t-pro-android-12-oxygenos-12-open-beta-2/amp/ and since then the device is just booting in loops and not going ahead. I get the boot reason error as attached. The boot logo has also changed.
My device did not had developer module enabled nor had I backed up any data from my mobile before installing the update.
I desperately want to recover data from my phone before formatting it. Please assist. Thanks a lot.

Try to reboot into recovery, then normal reboot.

Did that already. No luck :-(

Sorry I cannot afford to format the device as I'm desperate to recover the data.

Take phone to repair shop to download data via adb commands using laptop
Also try switching slots in fastboot mode: "fastboot set_active other" and then "fastboot reboot"

I have ADB utilities on my laptop. I connect my device to my laptop via USB cable and then do "adb devices" on the command prompt. It shows no devices. Perhaps this happens because my device was not rooted? Is there any other way I can access files on my device using adb?

Please can you elaborate a little more on this? Where to switch slots? Can we connect over WhatsApp or a ZOOM call please?

Enable USB debugging in developer options

The device needs to be booted successfully to enable USB debugging. Booting is the fundamental problem. How can I enable USB debugging without booting the device?

Phone needs to be off. Try holding down vol. Down button, power button til it reboots into bootloader mode while plugged into usb-c to USB-a cable to laptop. Then type "fastboot devices" on laptop while changed into adb subdirectory with "command C:/ prompt"

I appreciate you trying to help me promptly. Thank you.
I tried doing what you advised. The command did not show anything. Photos attached.

You need to unlock bootloader by using Superboy msmtool, but will lose all data
[CLOSED] T-Mobile 7T Conversion to International WITHOUT unlocked bootloader/SIM unlock!
Here is a patched MSM download tool for TMobile OP7T. It will bypass the need to sim unlock before unlocking the bootloader, and will also bypass the need of an unlock token file from OnePlus (hence skip the wait period of 1 week to get the...

You shouldn't mess with oos12 with locked bootloader as it can lose data
You could try to manually flash each file using fastboot (fastboot devices must show a number so install correct OnePlus and adb drivers for windows 10) --use payload dumper to extract all files from payload.bin from Indian op7t rollback zip below. Just don't do "fastboot -w" as that will format your data

Thank you. I have just started downloading this file (2.6 GB) on my laptop. Yes I am very keen to save my data before formatting. Please can you guide on the next steps to do after the download completes?
I use Windows 7. Is there a link to install correct OnePlus and adb drivers in Windows 7?

Right OK so I have downloaded the ZIP package and have also managed to extract the payload.bin file. See file contents in the attached image.
Please can you guide on the next steps hereafter? I use Windows 7. Is there a link to install correct OnePlus and adb drivers in Windows 7?

I think this is getting closer. I managed to install drivers as in the attached. Please take a look. 3 out of 4 have yellow triangles not sure if that means any issue. The 4th one appears only when I connect the device to laptop via a cable.

Only works on win10/11

OK. I still tried on Windows 7 and I got the attached. If I manage to change the slot from a to b using "https://www.droidwin.com/fix-failed-remote-slot-change-is-not-allowed-in-lock-state/", then will I loose any data? Again, I'm very keen to retrieve my data.

Thats sad :-( I'm looking for a solution to retain all my data in a situation where my device is just booting in loops (not reaching the home screen), developer option is disabled and USB debugging is also disabled. Please help.

All you can do is keep repeating reboot to recovery, normal reboot, reboot to bootloader, reboot to recovery, normal reboot, while praying and hoping that your phone boots up.

Does "fastboot devices" give you numbers and letters?
