Dragon Touch M7 [TWRP][Root] - Android General

The Mod edit sales link removedis a cheap generic 7" tablet powered by the MediaTek MT8127 SOC. It runs Android 5.0. It's old an hasn't been sold in a while, but maybe someone will still find this useful.
I used the excellent AIO-TWRP-Compiler Script by @yuweng to build this recovery.
Flashing Instructions
To flash this TWRP recovery image you will need SP Flash Tool, along with the rest of the stock rom files. M7-KD-HT-V2-MT-E-5.0-20150909 is the latest firmware. Unlocking the bootloader and using fastboot is not necessary.
In SP Flash Tool, go to the Download tab and select the scatter file MT8127_Android_scatter.txt from the stock firmware.
Select Firmware Upgrade mode. Do not use Format All + Download mode. This will brick your device.
Click the location for the RECOVERY partition. Choose the TWRP image.
Click Download.
Plug in the tablet and push the reset button on the back.
Booting Recovery
The M7 has no physical volume buttons, so you cannot enter the bootloader menu when you turn it on. Instead, you must connect it to a computer and then do
Code:
adb reboot recovery
After your device is rooted, you can download an app like this one to allow you to reboot into recovery mode. As a last resort, you can crack open the case. There are solder pads on the back side of the motherboard next to the HDMI port where the volume buttons could have been installed. Shorting the VOL + pad to the ground plane while pushing the power button will allow you to get into the bootloader.
Rooting
Install SuperSU in recovery, as you would any other device.

Too damn funny that I'm following this guide. And an hour into I realize you wrote it. What to do in case of memory mismatch error? hahahaha

lol, hi Mike. It means you have a tablet with a different memory setup and you need a different ROM for it. I don't think we ever found a ROM that works with those.

RK3066 Boot loop in recover mode

hi i purchase China brand rk3066 label as UG007 II
here the story
i wanted to flash finless rom on the stick but i want to backup my stock rom thru CWM
firstly i tried to root, using petrus. install it. run the reboot apk. when i choose reboot to recovery, my tv reboot and after awhile it goes back to home with ALL my apk missing. it seems that chat comand has factory reset my tv stick.
secondly i tried this method from Geekbuying website
install moroboro, and tpsarky successfully and my stick now rooted. moroboro successfully detect the rk3066 chip.
thirdly i want to install cwm as i want to do nandroid backup from here and choose genericrk3066 as i am not sure whether i should use imito or ug007 as this china brand tv stick
so.. following the method rename the cwm to update.zip and placed in external usd lashand reboot.
upon reboot, it goes stright to recovery menu ( it takes quite sometime to reboot probably few minutes). but unfortunately i cant move my mouse up/down. the cursur stuck at reboot system. when click the mouse, the stick reboot.
no matter what i do the cursur wont move and i cant highlite the install from sd to flash rom.
so no i am stuck at recovery mode.
worse part is the reset hole/button seems doesnt do anything. presing it while in recovery mode does not do anything.
if i press the reset button and connect microOTG to notebook usb (tried many method combination microOTG/power/reset), my notbook cant find the driver. if i able to do it, i able to flash new rom. but unfortunately. but Moroboro still can detect the stick when i install it.
anyhelp can extend to me please. i have open up the stick at techbliss website says you can short two point to go into mask recovery mode but the circuit is different:crying:
I able to flash new rom now. there's program to install rk driver. forgot to backup the rom before I flash new rom, now my wifi won't work anymore

[Q] Tablet only boots in recovery mode P3110

I have a Galaxy Tab 2 7'' Wifi (P3110) with CM 10.1.3.
Thing is, I wanted to install the latest nightly, so I booted in Recovery mode, tried to install the zip file and I had a Status 7 error. So after that I decided to stay with my CM version, but when I try to boot the tablet it goes to recovery mode and doesn't boot! I tried to wipe everything and still. I can't flash anything else (not even the CM version I already have) because I keep getting the Status 7 error.
I am desperate, I don't know what to do!
Well, you attempted to flash CM11/Omni with the wrong recovery, that's why you got the "Error 7"
Anyway, the problem should be easy to rectify.
1. Install ODIN3 on your computer (don't forget to also install the Samsung USB drivers as well).
EDIT In case you are about to install the drivers by installing "Kies" ... make SURE that NONE of the Kies components are running in the background (on Windows) once you try to flash with ODIN3 - or it won't work. If you Google around for a bit, there are several Downloads for JUST the USB drivers - I can upload you the USB drivers installer I used for my P3110 (flashed back to Stock to sell it off)) /EDIT
2. Download the correct .tar.md5 recovery file for the ROM you're going to use from Android Andi's file repository.
For CyanogenMod 11 you want to grab either PhilZ Touch or CWM Swipe Edition, for OMNI you want to grab TWRP.
3. Start ODIN3 and select the <recovery>.tar.md5 as a PDA file (make sure that nasty checkmark at "Repartition" is NOT checked"!)
4. Power on the tablet and make sure you get it into Download Mode
If it boots into Download Mode itself, that fine. If not just press... was it Power + VOL Down?... until you see the screen telling you to pres VOL up to proceed into Download Mode.
5. Connect the tablet to the computer (wait a second in case Windows decides to install the driver)
6. Flash the recovery
7. Disconnect after flash, jump into the recovery, flash CM11 or OMNI
Of course you can also flash back to Stock ROM (given you have the ODIN flashable tar.md5 at hand), verify that it boots after flashing, get into download mode, flash the custom recovery, flash the custom ROM.

Thanks! I didn't know that was a recovery problem!
Somehow I couldn't reboot into Download mode with the key combo so I used ADB for that, and flashed the new recovery with Heimdall (in the CMW official website the versions are old, maybe that was the problem...).
Then I installed CM.
Thanks again!

I am aware you managed to flash the ROM, but just as a hint about "this is a trap for young players":
IF your tablet is connected to the wall wart (power supply) or to the USB port of computer while trying to trigger the key-combo to hop into download mode or recovery it won't work! Your tablet needs to be _disconnected_!
Update Recovery!
hey you can try update your custom recovery to latest version by downlading the zip file here http://forum.xda-developers.com/showthread.php?t=2548257
and than try re-flash your current rom or any kitkat room for your device

Restoring stock ROM

Apologies for dumb questions but I am really newbie with Sony phones (I know my way around HTCs though).
I have the Xperia Z3 Dual (D6633). After some reading, I've managed to unlock bootloader, installed TWRP recovery and rooted the phone.
My wife somehow locked the phone without memorizing password and the brightest idea I've had was to perform factory reset. Accidentally, I have managed to perform a full wipe, wiping everything except mSD card (I have experience with CWM recoveries but not with TWRP). I did not backup software before accidental wipe.
Phone obviously wont boot but I am having hard time to get to recovery as well, phone just hangs with TWRP recovery logo on the screen.
The first step I intend to perform is to try to re-flash recovery again a go from there.
My intention is to restore stock ROM using Flashtool and d6633_23.0.f.1.74_1288-7362_r8b_ru.ftf
I've read how to enter appropriate boot mode, however, I am not sure witch one to choose for Flashtool to work. BTW, is it possible to restore stock software using Sony PC Companion software?
Can anyone point me in a right direction? A simple guide to follow to in order to get out of this tough situation?
Download your desired firmware and install latest flash tool on your computer.
Copy the downloaded firmware on to the flash tool folder which can be found on your C drive.
Hold volume up and power together till your phone vibrates thrice (power shut down)
Now open flash tool, select flash mode and then your firmware. Now press start.. You will see animation there asking you to connect your device.
Hold your phone's "down volume button" and connect it to the computer. Flash tool will recognize the device and starts flashing. Wait for it to finish.
Boot your device and you are good to go!

Success! Thank you for your hand holding.
Order of steps to get the phone to flash mode was slightly different in my case though. When I pressed volume up and power key the device did not react. Repeating the same process with USB cable inserted worked. When pressing volume down the phone was tying to get to recovery but then it hanged there. In the end when Flashtool asked me to connect the phone, I've kept pressing volume down key with phone turned off and inserted USB cable and it got recognized and software got flashed in the end. BTW, Flashtool does't contain drivers for Z3 yet, therefore I've installed drivers for Z1 / Z2 in addition to flashmode and fastboot drivers.
Currently I am updating software trough Sony Update and then I will check if bootloader is still unlocked ant will try to get to recovery. If no luck I will reflash recovery.
Thank you again!
P.S. I've noticed that there are slightly different application included in this ROM. FTF file in these forums is a slightly different version that came with my phone originally. It might be useful to get more versions of FTFs for D6633 model uploaded...

boot problem

When i boot or reboot my rooted my Samsung galaxy grand prime g530h it directly enters in recovery mode , WHY ?
Due to this problem my mobile does not show battery percentage while charging switched off mobile.
Even when i have not installed any rom , why does this problem occur ?
The only thing i did was just rooted my mobile using odin .
But , I do have custom recovery CWN
Why does it boot or reboot in recovery mode ?
What should i do to solve it ?
Need an quick answer .
Depends on the situation on why it boots to recovery. Probably would need more information. Do you have a custom recovery and if so what one? What were you doing before this behavior came into play. Please give as much detail as possible and I might be able to help you. Or someone else can.

Wow. Sounds to me in my opinion that u soft bricked your device. But have no fear. Samsung devices are virtually impossible to perm brick as long as you operate Odin correctly. First thing your going to have to do is find an custom recovery to put on the device. In my opinion as soon you rooted you should of done it because people do make mistakes.
I do not own a Samsung device personaly my wife does but she won't let me touch it LMAO. Try searching on Xda for Samsung galaxy grand prime g530h softbrick

Universal unbrick guide:
Terminology - types of bricks:
Soft brick - often occurs in the shape of a bootloop or any other problems with booting such as always getting to recovery or not getting past the carrier logo. This type of a brick, which shows some signs of life, can in most cases be fixed.
Hard brick - As the name implies, your phone can essentially used as a brick and it shows no signs of life. This kind of a brick is rare and in theory should be unfixable. However there are advanced methods of fixing your phones such as JTAG, but they require extra tools and accessories.
The decision:
Is my phone soft or hard bricked?
If you answer yes to all of the questions below you probably have a hard birck:
Test as said in order!
Nothing happenes when you hold or press the power button
You cannot get the screen to even turn on by pressing or holding any combination of buttons on your phone
Nothing happenes if you do the same as about but with your phone plugged into a charger
Nothing happenes when you plug your phone into a computer
When you plug in your phone into a computer it does not recognize it as a phone, storage or any other media device
Nothing happenes when you try all of the above again, but with removing the battery in between steps for 10 seconds and putting it back in again
Nothing happenes when you try all of the above again, but after leaving the phone plugged into a charger for 2 hours
If all of the questions are a "yes", then you either have a broken charging port and and a discharged battery or you have a hard brick.
The unbricking:
There are many methods of unbricking and they are all different to each phone. Here I will list the most common methods that often succeed.
Samsung users skip to 4. method.
1. If you have access to a stock recovery:
Method 1:
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Choose “Wipe Cache Partition”.
5. Choose “Wipe Data / Factory Reset” to delete all your settings and apps, using the correct ROM.
6. Reboot your device.
Method 2:
Download the stock rom for your phone. It should be in ".zip" format. Make sure it's the official version
(Find it by Googling something like "[your phone model] stock rom")
Put the file on your phone's external SD card.
Make sure that the rom is for your exact phone model.
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Select "apply update from external storage"
5. Navigate to the zip file you copied to your phone
6. Install it.
If you get Status Error 7 that means you didn't download an official stock rom.
2. If you have access to a custom recovery:
Method 1:
Try stock recovery method 1
Method 2:
1. Find a stable custom rom for your phone or if you want to download the stock rom
Make sure that the rom is for your exact phone model.
2.. Copy the zip file to the phone's external SD.
3. Install the zip
(If you have a custom recovery you probably know the drill)
3. If you have access to fastboot mode:
First install ADB and fastboot drivers (if you haven't already):
To install it on windows there is a handy tool called the 15 Second ADB installer which will install pretty much everything you need.
On Ubuntu install with:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
On Fedora:
Code:
sudo dnf install android-tools
On OS X using Homebrew:
Code:
brew install android-platform-tools
Once you have the drivers installed you have to find a recovery image for your phone to install a custom recovery.
You can try one of the popular recoveries such as CWM or TWRP.
You need to get the recoveryNameHere.img file for your phone.
Find it by Googling:
"[your phone model] TWRP recovery"
or
"[your phone model] CWM recovery"
Make sure that the recovery is for your exact phone model.
Now on your phone enter fastboot mode:
Turn your phone off.
You can try different button combinations. For my phone it's holding power and volume down buttons.
Once you're in fastboot mode plug your phone into a computer and open your terminal/cmd.
Type in:
Code:
fastboot devices
You should see a list of devices. There should be only one device ID number.
If you see the ID it's working. If you don't you didn't install the Google USB driver properly (on Windows) and if it says "'fastboot' is not a recognized command" or "No command 'fastboot' found" then you didn't even install your drivers.
If you have problems with installing Google "how to install adb and fastboot drivers"
Now that you know fastboot is working type in:
Code:
fastboot flash recovery C:\Path\To\Recovery.img
Replace "C:\Path\To\Recovery.img" with an actuall path of the recovery file you downloaded.
It should say success.
If it doesn't try to execute:
Code:
fastboot oem unlock
This will delete all data you had on your phone (games, game progress, apps...).
Now try
Code:
fastboot flash recovery C:\Path\To\Recovery.img
again.
Once you're done type in:
Code:
fastboot reboot
And your phone should still not work. Now what you have to do it try the custom recovery method above (number 2.)
4. If you have a Samsung device:

Question No Download Mode - bricked S21+

Hi,
I've managed to brick my S21+, after a mistake during flashing of a newer twrp version with Odin.
I basically placed the (patched) stock AP file in the AP slot instead of the TWRP tar, and the vbmeta_disabled_R.tar in the userdata slot.
After reboot, I got a boot loop, and I am not able to boot to recovery or to download mode as before when using the key-combo.
Previous to this flashing, I had the TWRP 3.6 and Lineageos 19 GSI for about 6 months, with no issues.
My question - how can I get to Download mode now? and is it possible that I ran over my recovery?
Is it possible that the download mode is no longer available due to the AP flashing (no BL, CSC files)?
Appreciate any suggestion and help!
connect it to the PC and do the combination that you did before, that is volume up and volume down pressed at the same time, that same thing happened to me, when I wanted to update twrp better install the stock first and then the new recovery, so you take advantage of updating the firmware of the phone and the new recovery
Strangely, the recovery entry or download does not work without being connected, so I recommend you better install the magisk to enter the recovery from there, otherwise you will have to do that process when you want to update or install custom roms

Thanks for your reply!
the key-combo in S21x are with USB plugged to PC, otherwise recovery cannot be reached, unless using ADB command. I have tried this many times since the wrong Odin flash occurred, but nothing happens except from reboot, warning screen (about unofficial software) and reboot again.
Even previous to the bricking, typically in order to get to download mode in this device, you need to go through recovery first and then select download mode. Alternatively, adb reboot download command, but neither are now an option.
So my last resort was a USB-JIG device to get to download mode - but I don't know of any such device for a USB-C connection.
Anyone here has experience with that? or can direct me to such a device for the newer Samsung models?
Thanks!

Thanks for your help! - indeed the PLUS and MINUS volume keys with the usb cable plugged in gets you directly to d/l mode. I just tried it with the power key all the time, as in previous models, and that got me nothing.
Issue solved!
