Huawei Mediapad S7 - OD deleted, PC doesn-t recognize tablet - Android Q&A, Help & Troubleshooting

I tried to install new ROM on my Huawei S7-301u, i used CWMR and delete everything i should and started installation of ROM. Suddenly, od 30-40% installation broke. Of course, everything is deleted, and when I press Power&Volume+ i get message "Enter into fastboot mode. You can press POWER key for more than 10 seconds to reboot device." My PC can not recognize tablet when I connect it with USB cable (only in tray i can eject Android).
Can I fix it and how? Can I start CWRM from SD card? Can I install ROM from my PC? Any solution?
Thanks for help.

You certainly can install from your PC! Do as it says and boot into fastboot, then download the firmware of your device. (I can't post links, but a quick search of "Huawei Mediapad S7 Firmware image" should get you what you need)
You'll also need adb and fastboot (another quick search will get you those too).
At that point you should have a device in Fastboot mode and a computer with fastboot installed.
You'll be able to use commands such as "fastboot flash system system.img" to reflash your phone back to normal, from which you can restart your Custom ROM installation.
Again, I can't post links, but googling "How to flash an android .img" may help you greatly.

Lenovo K910 Stuck on Logo Screen

First of all I would thank Crowds he is the best reference that I've to return in case of any problem I face. (He doesn't sleep - any time I ask he immediately supports)
I bought Lenovo K910 and I've managed successfully to install new ROM "VIBEUI_v2.0_1443" and Gapps with Crowds support.
I advised two of my friends to buy this good and cheap phone. For one of them I installed the latest rom successfully. But with the other I had a big problem The phone stuck on Lenovo Logo.
I was trying to install TWRP 2.7.0.0 batch before installing my new ROM, but during installation and after the phone rebooting the batch command screen shows <Waiting for Device> and the phone is stuck on logo screen.
I tried to connect the phone to PC many times, but PC doesn't recognize the phone. When I try to turn off the phone by pressing the power buttons, the phone restart on logo screen like the shown in this video.
I've read in many site that I have to do the following:
Download and install "minimal adb and fastboot"
Just type on the command line without pressing Enter:
Code:
[COLOR="Blue"][B][I]fastboot [COLOR="Plum"][STRIKE]boot[/STRIKE][/COLOR] recovery.img[/I][/B][/COLOR]
you should place your recovery image file in "minimal adb and fastboot" directory
The phone should be disconnected from computer and completely off (press the Power button for 10 seconds - in my case the phone is restarting)
Press and hold both volume buttons, then connect the cable to the PC.
Once the phone vibrate, press Enter to execute the recovery command line
Click to expand...
Click to collapse
In my case when I press and hold power button the phone is restarting on logo screen so I have to wait for battery consumption
I tried many times with TWRP images but it failed...
I tried with CWM image and it succeeded to load, but I don't have otg cable to load recovery or ROM from usb storage (The problem was in installing TWRP and my ROM should has no problem)
I want to flash TWRP on phone not only loading by "minimal adb and fastboot".
I decided to flash TWRP 2.7.1.2 batch through modifying the batch file. I just used fastboot commands
Code:
[COLOR="blue"][I]fastboot oem device-info
fastboot oem unlock
fastboot oem device-info
fastboot [COLOR="Red"][U][B]flash[/B][/U][/COLOR] recovery data/recovery.img
fastboot flash aboot data/lock/emmc_appsboot.mbn
fastboot flash rpm data/lock/rpm.mbn
fastboot flash sbl1 data/lock/sbl1.mbn
fastboot flash dbi data/lock/sdi.mbn
fastboot flash tz data/lock/tz.mbn
fastboot reboot[/I][/COLOR]
Finally I succeeded to install Recovery and phone works well in the new recovery mode and the system mode that I've not update it yet
I want to share you the problem solution in brief:
Download and extract this file "flashrec TWRP v2.7.1.2" from here
Just select without executing "flashrec_Modified.bat" file from the extracted files.
The phone should be disconnected from computer and completely off (press the Power button for 10 seconds or wait for the battery to be almost empty)
Press and hold both volume buttons, then connect the cable to the PC.
Once the phone vibrate, press Enter to execute the recovery batch file
and as me the phone start the recovery mode in TWRP and can be rebooted in system without any problem
i must extract "flashrec TWRP v2.7.1.2 this file on phone or where? can u explain a

You need to carefully follow each steps in the method - if you short that magic pin and then connect the USB cable (with battery disconnected), your computer will report seeing the device at either COM port 9008 or 9006. Then you can download the factory image to revive the phone. Of course you need to have the right device driver installed. Like I said, as long as the hardware is not broken, this procedure will succeed for sure.
I love you man!

I have a similar problem with Huawei Y320-U030, MTK 6572, Android 4.2.2 with many malware infections. Almost all applications keep crashing, Factory Reset from Settings does not work, but I can do it from the recovery and it seems to complete successfully but when the devices boots, all user applications and files are there. I have flashed it with stock ROM and backup ROM from an other working similar phone, the flashing process completed successfully but when the device boots all user files and applications are untouched, even after formatting the whole flash with Sp flashtool, Volcano box and Miracle box! An applications called DU Speed Booster is set as device administrator with a pattern lock which cannot be deactivated. Uninstalling the imo application makes the device reboot and hang on Huawei logo untill the battery is pulled out. I can't install any new apk or root the device even using PC. Music, videos, and photos in the internal memory can be copied with a computer but cannot be deleted. Formatting the internal memory with a PC seems successful but all files on the device are intact. Very interesting case indeed.

Oukitel K6000 Pro - Cannot install TWRP

Hi all,
I'm not an expert with flashing ROMs/recovery and stuff, but I think I know the basics. So, if I was missing something, please forgive me in advance
I'm trying to install TWRP on my Oukitel K6000 Pro, but can't do it for some reason. The things I tried:
1. Rooting my phone w/ kingroot to install flashify. Kingroot failed to root my phone.
2. Via linux machine, using fastboot command. Fastboot failed installing the recovery (USB debugning was turn on. OEM unlocking was turn on, but I wasn't sure I even needed it). Error message I got: "FAILED (remote: download for partition 'recovery' is not allowed"
3. Using windows 7 and windows 10 machines to install it via SP-flash-tool (USB debuging and OEM unlocking was turned on). The SP-flash-tool did not recognized my phone.
4. Using SP-flash-tool with FWUL live-CD. It did not recognize my phone.
5. Using SP-flash-tool with linux machine. It did not recognize my phone.
As for #3 above, I was trying to install MTK drivers before performing the flash process. I think I got it right (for the win10 machine, I rebooted to a mode without signature check as required), but I'm not sure though.
If anyone can step in and help with that - I would much appreciate it.
Thanks in advance,
Tamir
you need the right drivers and the right adb tool.
Download adb tools of android sdk, google it.
Then download the oukitel drivers-> Driver_Auto_Installer_v5.1453.03, search for those., install them.
Try again, good luck.
Rooting and unlocking your phone will format your phone, beware of losing everything on it.
Btw, never use kingroot. Use latest SP Flashtool Version 1728,
Guide:
Download Magisk V16 or SuperSu to your micro sd on your phone.
--(Download your desired firmware, if you want to upgrade as well. (if you want, not needed, since you only want to root or install twrp)--
Download SPFlashTool compatible TWRP from a site that i can't mention here.
Turn off your phone.
Open Splflashtool, select the Android Scatter file that was downloaded with your twrp.
A little bit under that, select Download Only, and NOT firmware ugprade etc.
Now click Download, connect your turned off phone to your pc.
You should hear a windows sound, look at the tool and DO NOT Disconnect your phone. until a popup with Success and a green Symbol appears.
be patient and let it run. (shouldn't actually take longer than 3-5seconds)
After it is done, press simultaneously the Power and Volume+ Keys until a really small menu on the left side screen appears.
Now you can navigate with the Volume+ Key, from the top to the bottom, in an endless loop.
With the Volume- Key you can select on of the three options:
Recovery <-this is what we want, select it!
Fastboot (not really needed for us)
Normal (normal Reboot - Start of the phone)
You will now see the bootlogo, then the twrp menu will show up.
Now you can Flash Magisk or SuperSu for Root. Wipe Dalvik and cache, Reboot, Enjoy.

DOOGEE T6 Pro - Root ?

Hey there,
i was wondering if anyone got an idea how to get root access / TWRP working on a Doogee T6 Pro ?
I don't really find anything online that seems to be working and of course most one-click root tools dont work for China phones.
Anyone got any idea ? The official forums look empty as well.
It looks good

Some useful tips for rooting MAZE Alpha, perhaps will help you : MAZE Alpha root
Use the method I to patch your boot.img with Magisk-v14 and flash the result image, it must works
Here is the HowTo, have done it 3 times yet:
First, get the correct TWRP Version for Doogee T6Pro ( i dont remember where i got it, i can upload it somewhere if someone have a good location) and the SuperSu Zip.
Then, activate the Developer Options in the Device Settings and Activate the OEM Unlock and USB Debugging in there.
The next Step is to Boot the Device in Fastboot mode. you can either do it by USB with the Terminal Command: "adb reboot bootloader" or you can turn the device of and then reboot it by pressing the Volume Up Button and the Power Button simultanously (quite difficult, didnt Work every Time). You will get to a menue with 3 options: Boot to Recovery, Fastboot and Normal. Switch through these Options with the Volume Up Button and Select it with the Volume Down. Go To the Fastboot Option and Select it.
In Fastboot Mode, plug in the device to an computer and type the terminal command "fastboot oem unlock" (in windows, you have to install the fastboot tools. i dont remember that i had to install them in ubuntu... im not sure). this will wipe the whole data of the device. its important to reboot the device afterwards normaly. otherwise it could happen that you get stuck in an bootloop later ( happend twice to me ) this normal system boot will last much longer then normal, so get a coffee or tea
the next step is do get to fastboot mode again and then send from your computer the command: "fastboot flash recovery twrp-recovery-filename.img". this will flash the recovery.img on the recovery partition.
than go to the bootloadermenue and this time you dont choose fastboot but the recovery option. this will start TWRP
while TWRP is running, you can copy the SuperSU zip to the device with Nautilus or in windows systems with windows explorer. then select "Install" in TWRP and select the SuperSU.zip.
After the installation, reboot to normal system and you are ready with rooting!
if something goes wrong, it can happen that booting to normal system will get you stuck in an bootloop. the last time i could repair the system by booting into recovery (TWRP) and select the Wipe menue and there the Format option. the other time i downloaded the original system from Doogee and flashed all partitions. im not sure if that was necessary.... but who knows :fingers-crossed:

Question How to fix bootloop?

I tried to root my phone using this guide, followed it down to the word and yet my phone's stuck in a bootloop. It keeps restarting to the Poco start screen.
Ive got the stock recovery, and for some odd reason fastboot commands work only in the "FASTBOOTD" screen and not the the "FASTBOOT" screen which you get from "adb reboot bootloader" command.
I try to shut it down and it boots up back again in the same screen and is stuck there.
Im clueless and I really dont know what to do. Some help would be greatly appreciated.
edit: I tried to use the stock recovery and wipe data. No progress.
I tried to connect the phone with the MIAssistant but the app doesnt recognise the device.
I tried using the MiFlash tool to flash the stock rom, it goes on infinitely. Im currently trying to use the SP Flash tool and MediaTek Bypass tool but I havnt got any progress yet.
I promise I'm never buying MediaTek devices ever again.
Careful with the Flash and Bypass tools, they can cause problems.
What can you achieve with the hardware buttons on the phone? Can you get it into recovery?
Fastbootd working but fastboot not sounds like a USB drivers problem - there are some driver options here.

It was a driver issue, thanks for the link.
What I did to get out of the bootloop:
1. Download the latest Miui rom for your version, make sure it's the recovery version and not the fastboot one.
2. Press ALL the buttons, Vol+ Vol- and Power button to shut it down for a few seconds (assuming you can't switch it off as it keeps powering back up again).
3. After it's switched off, quickly press the power and vol- button until you see the FASTBOOT screen.
4. Connect with PC, make sure you have the proper drivers and have connected with the right USB port.
5. Download OrangeFox custom recovery. It is a unofficial custom recovery, so its stability is questionable. But it does the job here.
6. Copy the OrangeFox zip and the Miui rom file to your phone's SD card or any external storage which your phone can access.
7. In your PC, extract the OrangeFox zip folder in your platform-tools folder. (The folder where you run your cmd fastboot/adb commands)
8. Open up cmd, and enter the command:
fastboot flash boot recovery.img
9. Your phone should boot up to the OrangeFox recovery. If not switch the phone off (Step 2) and press power + vol+ button for booting up to the recovery.
10. Locate your OrangeFox zip installer file in the recovery and flash it.
11. Reboot to the recovery again.
12. Locate the Miui rom and flash that. Before swiping to flash the rom, there is a check box which says something like "flash OrangeFox once the rom has been flashed". If you want to keep OrangeFox as your recovery then check it, or else leave it unchecked. Flashing roms remove custom recoveries.
13. Your phone must reboot to miui.
NOTE: You can use fastboot commands to flash the rom but I'm not very familiar with fastboot commands (I actually forgot most of them). Hence I use the recovery method.
