Stuck at bootlogo / adb devices doesn`t recognizes TF300 :(

Hi all! Please help me
I booted at TWRP and tried to restore the stock ICS..
now i'm stuck at bootlogo..
when I turn it on with vol down pressed I can select fastboot mode.. it says "Starting fastboot usb download protocol" but I cant get the device listed at ADB devices
i doubled installed all drivers following the noob thread.. but no device listed with adb devices...
any chance to get hard bricked only restoring the stock rom?

When you go into fastboot, try fastboot devices instead. If you have that you should be able to flash in recovery if you need it and possibly use that to flash in a stock ROM.

C:\android-sdk-windows\platform-tools>fastboot devices
00000 fastboot
this is good?

can I flash TWRP thru the methoed described at their website?
Install Fastboot Method:
You will need fastboot for this method. Download the above file, check the md5, rename to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere). Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm). The device will now be in fastboot mode. Plug the device into your computer. Run the following command via the command line:
fastboot -i 0x0B05 flash recovery twrp.blob

flashed the twrp.blob but didn`t make effect
i'm still stucked at bootlogo and accessing my tf300 only thru fastboot
which recovery should I try to flash?

My mistake was that a long time ago I made a full backup.. including boot, cache, etc.
When I restored this backup I think the TWRP has been overriden..

[Q] OnePlus One - Unable to unlock bootloader again after relocking

Hi Guys,
Hope to get some help here.
So i unlocked the bootloader of my one plus one and installed supersu + Twrp recovery. All worked fine until i decided to relock the bootloader.
I've put the device into fastboot mode and executed "fastboot oem lock" with twrp recovery still in there.
Now i am trying to unlock the bootloader again using "fastboot oem unlock" to be able to flash the stock recovery and having issues.
output of commands:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
OKAY [ 0.004s]
finished. total time: 0.005s
C:\Program Files (x86)\Minimal ADB and Fastboot>
After this it boots straight to twrp recovery. I then hit reboot system and go back to fastboot mode and run the below:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery recovery
.img
target reported max download size of 536870912 bytes
sending 'recovery' (12260 KB)...
OKAY [ 0.389s]
writing 'recovery'...
FAILED (remote: Device not unlocked cannot flash or erase)
finished. total time: 0.404s
Anyone has an idea how i can unlock the bootloader again ?
Thanks
Vik

Would it let you reflash the stock factory image thru fastboot? Maybe if you could do that it would let you unlock again. And it would give you stock recovery.
Or else what about the option in developer settings to update the stock cm recovery when installing an update. Maybe you could install an official update thru TWRP and get stock recovery back?
Just throwing out ideas, hope you figure it out

I've documented ths same issue describe here: http://forum.xda-developers.com/oneplus-one/help/locked-bootloader-twr-rooted-t2820341

Hi YrrchSebor,
Thanks for the reply.. I already tried all that, even using adb sideload and keep getting same error as mentioned above. I'll try the solution lemonspeakers suggested later today and post the outcome.

Be careful if you updated your phone to XNPH30O OTA,
!!! Warning !!!
In the NEW OTA CM11S XNPH30O, the bootloader (aboot) img size changed....
We request all not to apply the unlocker scripts on the new bootloader , until we confirm/find the new bit position.
It might brick your phone and corrupt bootloader...

It won't work.. do not try it if you updated to XNPH30O using the OTA.

I ran this command:
Code:
fastboot.exe boot TWRP-2.7.1.0.img
But the next step does not work:
Code:
It will boot your phone into recovery once from the recovery image
stored in your PC temporarily
then you can flash the zip either by sideload or from sdcard...
I got:
downloading 'boot.img'...
OKAY [ 0.484s]
booting...

That's because you can't boot a recovery with the recent bootloader unless you're unlocked.

make sure you have the a700 and not the a701 or a510 etc etc....
also, you could try booting directly into fastboot:
1. power off
2. hold power and volume down, while you're doing that, constantly change the rotation switch from lock unlock lock unlock.... keep doing it for about 5 seconds
try flashing from here... it might give you the same result but worth a try.
other possible problems:
1. the recovery you downloaded is corrupt
2. the recovery you downloaded was not a working version
3. you might not have the right usb drivers installed
4. you might have used the wrong recovery commands
5. command (sometimes) needs to be Run as Administrator on Windows (right click)
6. you might have waited too long to reboot to recovery, or used the wrong method to do it
it might make it easier for you if you just rename recovery on computer to recovery.img (so you can just type fastboot flash recovery recovery.img)
also, I have uploaded a copy of the recovery I'm using (it's newer)

you can also try (while in fastboot)
Code:
fastboot boot twrp.img
(or any custom recovery)
It should boot without flashing, and from there you're will be able to flash firmware, ROM, etc...

it might be fine but personally I would not try that... recovery and boot are not to be confused and bootloaders are not to be messed with

THL T9 Pro request Root Method

Hey there,
i just bought a THL T9 Pro from Amazon.
Tried Kingroot, Framaroot, some PC Tools such as vRoot but no success. The Phone works with SP Flashtools and with issues in MTKDroidtools. Biggest Issue here is i cant generate a scatter file, when hitting block-map button there is only one block 0000000-000000 and the programm stops with error.
Does anyone know how to root this Phone (MTK6737) please help
SOLVED: go to This Post for a working solution for almost everyone thx to Evolym and juanamores.

Hi Hivescore!
I have the same problem as you and I have still not been solved.
I just bought a THL T9 Pro from Amazon, too.
The correct method seems to be that it is through TWRP recovery installed with SP Flashtools.
Once that process is done, download the SuperSU, restart in recovery mode and install the zip.
Do not provide download links because I do not allow me the forum for not having enough publications.
If you find any solution please send me private message or answer for this thread.

hey juanamores,
i ported twrp 3.0.2 for our device (thx to jemmini) and flashed su.zip from there. found out two solutions that work:
1.st Solution boot TWRP using Fastboot.
2nd Solution Flash TWRP using Fastboot.
anyway you need to unlock your bootloader first. (menupoints are in german because i dont know the exactly points in english xD )
Einstellungen -> Über das Telefon (About) -> 7-8 times tap Build-Nummer ->
Back, then Developer Options -> tick OEM-Entsperrung - tick USB-Debugging. now plug phone into pc allow the pc in the box appear on phone (this maybe pops up as soon as you start adb).
now open cmd with adb and type:
adb reboot-bootloader
wait until your phone is in bootloadermode (Fastboot... on Display)
type
fastboot flashing unlock
a message on your phone should appear about unlocking your bootloader follow it (this will WIPE your phone)
after complete, boot your phone again into bootloader (by adb command or when phone is off hold vol down and power until thl logo appears then release power until bootloader boots). in the meanwhile copy attached twrp.img to your fastboot/adb folder.
back into bootloader, type
fastboot boot twrp.img
twrp should boot up.
if you want to permanently flash twrp to your device i found the following solution:
copy twrp.img to your phones internal sd card by typing
adb push twrp.img /sdcard/
in twrp select Install -> on the next screen select image on the right side of the screen, select storage and find twrp.img in root of your sdcard, select recovery as partition and swipe to flash. Reboot Recovery to see result.
Flash su.zip to gain root access.
su.zip is attached
twrp.img download: here
Hope this works also for you

Hi Hivescore!
I followed all the steps but could not make it work.
When phone reboot, it does normally boot, not TWRP boot.

This worked for you?

Now I understand why it does not work for me!
There are 3 versions of THL T9 pro phones.
MT6737 - 1,3 GHz
MT6737M -1,1 GHz
MT6737T - 1,5 GHz
My phone is the first on that list! MT6737
The recovery that jemmini posted is for the second MT6737M
Could you get me the TWRP recovery and if possible the scatter for my MT6737?

hi juanamores!
could you please share your solution?
the link you gave leads nowhere.
I experience the same problem as mentioned above:
I unlocked the bootloader and try to boot or flash the twrp.img but it just boots android as normal.
I checked if I succesfully unlocked my bootloader by
Code:
$./fastboot flashing get_unlock_ability
and it prints the size of the bootloader, so it's okay I guess (?)
I used both of these commands:
Code:
$./fastboot boot twrp.img
Code:
$./fastboot flash recovery twrp.img
I'm not shure what went wrong but when I boot to recovery the old recovery shows up.
-> it can't have been overwritten with the twrp.img OR twrp.img contains the old recovery as well (what I doubt).

You have to use SP Flash Tool v 5.16.20.00 to flash recovery.

After flashing a Custom Recovery, If you want to boot to recovery, the actual command through fastboot is
Code:
fastboot boot recovery
or also in the bootloader screen you can press vol+ button untill you see Recovery mode then hit Power button.
The most important point is After flashing a Custom Recovery you must flash the vbmeta with Verity command To make it permanent. Otherwise it'll just revert back to Stock Recovery. (This method only works in Color Os (ie., Android 9), for RealmeUI you need additional thing to do)

Where do we get this vbmeta from? I'm having the same problem, that after flashing twrp.img it just reboots back into fastboot mode. Is this because Secure Boot is enabled and does vbmeta disable that?

After flashing recovery via cmd, you will go back to fastboot on your screen. Navigate the volume buttons til it show Recovery mode on top of the screen. Then press power button and it will boot to recovery.

It turned out the problem was Orangefox. With TWRP it booted into Recovery fine when I selected that option but with Orangefox it would just reboot into fastboot. I'll try some different versions of Orangefox sometime but for now my biggest problem is that it's impossible to set a Lock Screen PIN/Password, let alone use FingerPrint. It seems unlocking the bootloader breaks the security settings.

whats orangefox ? did u found a fix !

I rooted 5i and no use your code. I follow this video
Some code:
adb devices
adb reboot bootloader
fastboot flashing unlock
fastboot devices
fastboot flash recovery REALME5i.img
fastboot flash vbmeta vbmeta.img
adb reboot recovery
