TF300T 4.2 TWRP Error

Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!

I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.
Thanks

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.

You are amazing. I will give it a try tonight and report back!

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Put the twrp.img into your ADB folder, where you installed it. Then run the next command.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...

I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

I've tried every firmware and unlock tool combination. Nothing works. I sent them an email a day ago. Depending on there response, maybe I'll try calling. I'm so fed up with this tablet, I'm about to throw it out my window. $400 POS. :good:

Did you ever get your tablet fixed? I am having some problems myself after a miserable m9 update.

Can I still install any recovery(CWM or TWRP) after I have forgotten my password?

My question is: Is there any way that i can install any custom recovery now, when I am locked out of my phone, so I can try Method 7 from this post . I have enabled USB debugging, but for some reason, my device is unauthorized from executing adb commands.
I have Xiaomi Redmi Note 3, and have forgotten its password. I have tried Method 2, 5 and 6 from this post, but to no avail.
I tried method 2 and 5 which requires ADB to be installed, but I was not able to access my phone. I have USB debugging enabled and my phone is not rooted. When I tried to run the following code:
Code:
adb devices
adb shell
it showed that my phone is unauthorized and error: device unauthorized This adb server's $ADB_VENDOR_KEYS is not set
Here's the screenshot:
When trying method 6, I had to change the path of ADB driver because the file I downloaded from the post, had its own ADB driver which clashed with my already installed ADB driver, but even after that, it again showed the above error. Here' the screenshot:
Finally I want to try method 7 from the above post, which requires custom recovery to be installed on the phone, is there any way now?
Though it seems now that the I have only one option left and that is to factory reset my phone, but if , there is any other way by which I can bypass my lock screen, please please please inform me.

Of course you can. Just boot your phone into fastboot and do "fastboot flash recovery <recovery image name>.IMG" and you'll flash it. And you can't access the adb because your screen is locked... This is how companies prevent phone hacking
So flash custom recovery, backup the /data , factory reset and after resetting restore the /data backup. And you're good to go. I suggest you using TWRP, because I use it and it never left me hanging Keep me updated.

OK... So first boot into fastboot. When you've done that, connect It to your pc with usb, download fastboot package from somewhere on xda(you'll find it).
Open command prompt "CD" to the directory where your fastboot is located in, put recovery image in the folder where fastboot.exe is and type "fastboot flash recovery <recovery file name>.IMG". I'm gonna update this answer in 2 days, when I get to my pc, so try to do it by these instructions, if something isn't working, comment and we'll resolve the problem. If something isn't clear, just ask. Keep me updated.

Can unlocking my bootloader somehow brick my phone?

Everything can brick your phone. Updating my lenovo phone with official update hardbricked mine... But yeah, it can.

[Guide] BQ Aquaris M10 (freezerhd) twrp & root

Hi,
as I did not find an English guide for rooting a BQ Aquaris M10 tablet and had some problems when trying to root my tablet, I want to post an guide how to root this tablet.
First of all:
- This guide is just from my experience and is not thoroughly tested. It's on your own if you risk bricking your device.
- If you get stuck in the process, in nearly all cases you can revert to stock with the MTK flash tool (can be found on mibqyyo.com) and the images provided by BQ on their website.
- I could not unlock the bootloader with the 1.X-Images (Lollipop), as the VolumeUp-Button didn't work in fastboot-mode and you need this button to confirm the unlock.
- Booting into recovery from start with VolumeUp and Power-Button. This doesn't work with the 1.X-images, too.
- This guide is not intended for users without experience in unlocking/rooting a device. If you don't know how to use adb, fastboot, recovery and things like that, don't try it!
- You will loose all your data during this process!!
Guide:
Modify boot.img, flash new firmware
SuperSU in systemless mode doesn't work on stock image, as the SuperSU installer can't extract boot.img. You have to repack boot.img.
I tried a SuperSU installer without systemless-mode, but device didn't even boot anymore afterwards.
This guide is derived from a Spanish tutorial on the HTCmania-forum ("Root M10 HD Marshmallow") by yquepongo. Thanks to him!
Get a firmware for your device from the BQ-website (should be Marshmallow, see above) and unzip it to a directory.
Extract the boot-verified.img in the firmware directory with a bootimg-extractor. There are various tools available.
I used bootimg.exe, because this was explained in the mentioned thread and I even used it with wine on Linux and it went well.
Search for cpiolist.txt in your extracted boot-verified.img and delete the first two lines:
mode:mtk
mtk_header_name:ROOTFS
Repack boot-verified.img and put it back in the firmware directory.
Flash the modified firmware with the MTK flash tool according to the tutorial on .mibqyyo.com (Title "Hard Reset for the smartphone range Aquaris and Aquaris E"). In short: Disconnect device, start Tool, load scatter file from firmware directory, choose firmware upgrade, start download, connect the device in power off state, download will start automatically.
This will delete all your data and put the device back to factory rom (hard reset)!!!
If you don't want to flash the complete firmware, you can flash only the boot-verified.img with "Download only" in the flash tool. I didn't try this and don't know if this is working.
Start your device, don't activate any security settings to prevent encryption of data partition.
Unlock bootloader, flash TWRP, install SuperSU
Enable developer settings on device and activate "OEM unlock" in developer settings.
Reboot into fastboot (adb reboot bootloader) and unlock bootloader (fastboot oem-unlock).
This will delete all your data!!! Reboot your system afterwards to make sure everything is still ok.
Do not activate any security settings and make sure your data partition is not encrypted!
The existing TWRP-image can't handle an encrypted data partition, you will end in a boot loop and have to start the whole process again!
Double check, your data partition isn't encrypted. (Settings - Security)
Reboot into fastboot (adb reboot bootloader) and flash the TWRP-image from the TWRP-site (fastboot flash recovery twrpxxx.img)
After reboot TWRP should start.
If you have checked that everything is ok (I would recommend a reboot into normal mode), you can install SuperSU with the standard-installer-zip in TWRP.
If you didn't modify your boot.img, the installer will give a warning that it cannot extract boot.img and you will not find any SuperSU on your system.
If you get stuck in bootloop afterwards you can start anew and try it with another image flashed with MTK flash tool. (Firmware 2.2.0 from December 2016 for freezerhd worked in my case)
Maybe some steps could be shortened, but I haven't tried it.

hi zrfl,
i have a bq aquarius m8 with mm os.

Sorry, but I can't help you there, as the M8 seems to be too different to the M10: I didn't have to unlock the boot.img, it was easy to unpack.

this is the only way to root this device !!
thanks a lot ...

Thanks for this tutorial.
I've followed all the step, I'm able to flash the new recovery from the TWRP website but then I do a
Code:
fastboot reboot-bootloader
but the device reboot normally, just with a warning message during boot saying something like "This device is unlock and can't be trusted, it will boot in 5 seconds".
So I'm unable to access TWRP recovery, I guess when the device reboot it override the recovery partition because if I do a
Code:
adb reboot recovery
I end up in the Android recovery not TWRP.
Any idea ?
Thanks

Sorry, I have done this a long time ago and don't know what could be wrong:
You have the correct message, so unlock was successfull
You try to reboot in fastboot, so you flashed TWRP correctly in fastboot-mode
And I don't have the device at hand to try it myself. But I do have a few suggestions, what you could try:
Don't try to shorten procedure with unlock and flashing of TWRP at once. I'm not sure, but I think I had problems when I tried this. So do a normal reboot after unlock, before booting again into fastboot and flashing TWRP. (Now you have done this already )
I don't remember the proper boot command after flashing of TWRP. But
Code:
fastboot reboot-bootloader
doesn't make sense: You are already in bootloader.
Is there a boot-option in the bootloader where you could choose recovery?
Otherwise better power off and use the key-combination for booting into recovery: VolumeUp+Power.
I think, you have to repeat the procedure, as recovery seems to be overwritten: Boot into fastboot, flash TWRP, reboot into recovery. And avoid normal booting before first boot into TWRP!
Did you use the newest TWRP 3.1.0 from March 8th? I haven't tried this yet, so there could be the problem. You could try the previous one: 3.0.2 from last year.

Thanks, I succeed with the combo key (power + vol up) directly after the reboot process

Perfect it's working great now !

I did exactly what you wrote but SuperSU won't install because it cannot extract the ramdisk...

Hi @zrfl
Thanks for your posting!
I did as you suggested and successfully unlocked bootloader and installed TWRP 3.1.1. Your hint to modify the boot-verified was extremely helpful, as I wouldn't be able to unlock the bootloader otherwise.
However, I did not manage to install super su. And boy, I tried many different versions od regular/system/systemless supersu, each flashed according to the respective how-to.
I ended up either in a bootloop, or get stuck on the Android logo at boot.
Flashing goes well until this step:
"Decompressing ramdisk
--- Failure, aborting"
I checked ramdisk compression of boot with Carliv image Kitchen and it tells me that it already is set to "gz" and not another compression TWRP can't handle.
Please help me on how to flash SuperSu.
Thanks and best
Tom

There is something wrong: TWRP does not need a modified boot.img.
Maybe newer ROM-versions are different.

Solution for geting root on BQ M10 FHD on stock rom 2.6.2: Start with a fresh system and install magisk beta (not stable), reboot and root is granted!
tanks a lot to @scafroglia93!

Are there any Custom ROM's
For this Tablet like CM/LineageOS AOSP etc?
Googling reveals nothing and Considering all the kernel mods like hardcore and Ubuntu touch I find it hard to believe that nobody has built one of the later.

I've been searching for custom ROMs too. Apparently, there are none available at present. However, I'd highly appreciate lineage rom.

help with rooting a oneplus 6 using linux terminal (not windows)

This is my first time rooting a phone but Im defiantly in over my head and think i almost broke the oneplus 6 when i was trying to enter commands in the linux terminal. So far I have unlocked bootloader and am currently stuck trying to figure out a) what exactly the twrp recovery really does, b) which is the right files to download, c) the proper commands to flash custom recovery in a linux terminal. Thanks in advance to anyone who can help me.

Command you need is fastboot boot (recovery name). Replace recovery name with whatever you called the download of the twrp image file.
Twrp is necessary to flash custom ROMs, kernels and magisk.
After flashing rom you need to flash twrp zip of your choice to maintain recovery otherwise it is overwritten by stock recovery.
There is a helpful guide I will post the link to

The commands for Linux and Windows are nearly identical. You just need to use the Linux version of adb instead of adb.exe.
TWRP is a custom recovery. It's similar to the GRUB bootloader for Linux, but more touch interface friendly. It allows you to make edits to the system, backup the system, and install custom zip's for the system.

Instead of trying to flash twrp from fastboot do a sudo fastboot boot <image name> then flash the zip while in twrp...

Thanks bkeaver for the advice and im glad to say I finally got that phone rooted. One more obstical I experienced was the phone not booting into twrp instead it was locking up on a screen that said Qualcomm crash dump mode. I unplugged and rebooted by holding the power button. From what I could read online it had to do with compatibility issues with Android pie. The Blu_Spark TWRP img and zip files seemed to do the trick. Anyone else who is experiencing the same issues I suggest you read this page: google.com/amp/s/amp.reddit.com/r/oneplus/comments/9iid4e/unable_to_flash_recovery

In oxygen OS ver.9, you must download "twrp-3.2.3-x_blu_spark_v9.86_op6.img" and "twrp-3.2.3-x_blu_spark_v9.86_op6.zip" from https://forum.xda-developers.com/devdb/project/?id=27466#downloads ,
and launch twrp from this command "fastboot boot twrp-3.2.3-x_blu_spark_v9.86_op6.img".
After your device boot trwp, you can install "twrp-3.2.3-x_blu_spark_v9.86_op6.zip" from your device's internal storage (if you copy into it) or adb side-load mechanizm.
Once zip installed, you don't need to run fastboot to boot twrp recovery (only you reboot the device to fastboot mode and select recovery, trwp boot up).

What's a syntax?

rhetorical question in the title and fyi I will never claim to be very tech savvy thanks for the info though

[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`

hello
im willing to port your amazing twrp to our phone UMIDIGI F1 Play and i need permission to do it ???

on other releases, no change was needed to boot on both. I would try as is first.
as long as you have working sp flash tool in case of issue.

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

thanks!
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.
:good:

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 ?

good
