You're not dumb. I don't know anything about this tablet but check to see if you find solutions here.

I agree with vanessaem.... You are not dumb at all, just a newbie. We all started out as a newbie ourselves
I just read on the forums for your device that there is a physical "Reset" button near the SD Card slot. Can you please try to stick a paperclip or pin into that hole and hold it down until the tablet reboots? I also read that these instructions may be in the manual as well.
If all else fails you can restore the tablet to defaults. I also did a quick search and came upwith the easy steps to restore it. These steps are from another forum so I will quote them since this is not my work.
I've only had this tablet a few hours, but managed to get to a point where it wouldn't boot pretty soon after rooting it. So after trying everything to get it up and running I finally managed it with ADB and fastboot, also it took from Android 4.1.1 to 4.2.1 - so here is what I did after reading various forums of problems with other Asus devices and soft-bricking other Android devices in the past - hopefully it might help someone one day.
You will need to install the Asus ADB drivers before following the steps below, if you haven't installed them you can get them here
1. Download and install Lightweight ADB and fastboot installer here from XDA
2. Create a folder called 'Fastboot' on your C: drive (it can actually be called anything but the prompts below refer to a folder with this name)
3. Download the CarePackage.zip file here and unzip the contents to C:\Fastboot, there are 4 files
4. Download your chosen firmware from the Asus web site - extract the zip file to reveal another zip, extract the second zip file, copy the 'blob' file to the Fastboot folder, there will now be 5 files in your fastboot folder
5. Reboot tablet, holding volume down, select the USB option (3rd icon) using volume down to cycle through icons and volume up to select and connect it to your PC using the USB cable
5. Run the Lightweight ADB and fastboot installer which will open the command line, enter the following commands;
c:\Fastboot
fastboot devices
fastboot -i 0x0B05 flash system blob
6. The following will now be displayed in the command line screen;
sending 'system' <1062567 KB> (the actual size will vary depending on the firmware selected) Also a blue bar will appear on your tablet screen showing the progress. It takes around 3-4 minutes to send the system files.
writing 'system' will then be displayed, this will take a further 3-4 minutes.
Once the files have have been sent and written the command screen will display something similar to;
finished. total time: 444.226s
7. Unplug the tablet and reboot it using the power button, you'll have a fresh install, all data, root etc will be lost.
For anyone who is struggling to recover their tablet or just actually update it I hope this helps

thanks for all advices, but i think this is a SERIOUS problem ..
i can't do fastboot, can't connect PC-ANDROID or vice versa
my android device has now only two modes / off or stoned when asus logo appears
RECOVERY twrp non reachable!
I have a Vibrant T959. I just flashed from the latest official Cyanogenmod (android 4.2), to the latest unofficial cyanogenmod (Android 4.4.4).
However the phone is crashing in the setup process. I need to get back into clockworkmod, however I have tried the hold vol+, vol-, and power technique tons of times, and it does not work. I had trouble with that method before but would always just use rom manager to reboot to recovery, but needless to say, can't do that this time.
I'm currently attempting to use the ADB to reboot to recovery (which I've never used). I installed the latest JRE, and downloaded ADB, however currently I am unable to get the drivers for my phone. I understand I'm supposed to launch SDK manager to download them, however SDK manager does nothing, just pops up an empty command window for a split second and quits. Did some searching to see if I can download the ADB drivers seperate, but just found many dead, or untrustworthy looking links.
Been reading for hours, but i'm stumped now. All I need to do is just get back to clockworkmod recovery. Is there any way to do so?
Well just an update, by sheer luck I found a roundabout way to get back into recovery. Apparently from all the web searching lots of people are having the same problem with the 3 button combo not working. Supposedly it might be hardware locked.
Here is what worked for me.
Hold volume down and power, and after a couple seconds plug in a usb cord (other end was attached to pc, but no software or anything running)
Keep holding those 2 buttons for about 30 seconds, you'll see the battery icon flash a number of times, along with a little round loading cursor type thing which will also be flashing.
After about 30 seconds, release the power button but keep holding the volume down button for awhile.
After about 10 seconds, clockworkmod recovery pops right up.

ADB will work. Use the process given below and let me know if it works
1. Install stand alone SDK tools from here, they should work. (h ttp://dl .google.com/android/ins taller_r23-windows.ex e)(Delete all spaces in between.)
2.Note the folder where you have installed SDK tools.
3. Move all the ADB driver files ( Probably 2 .exe and 2 .dll files, or just copy all the files from the ADB driver folder in which you installed the ADB drivers ) to the SDK tools folder.
4.Make sure all usb drivers for your phone have been installed. ( If not just google it, you will find them in the first or second link)
5. Connect your phone and make sure it is recognized by your PC.
6.Navigate to the SDK folder where you have also copied the ADB files. Hold down SHIFT and right click, Select Open Command Window Here.
7. Type adb devices .It should show you all the connected devices, mainly numbers. If not, the ADB drivers have not been installed correctly.
8. If Step 8 works, to reboot into recovery just type " adb reboot recovery " without quotes.
9. Your phone will reboot into recovery .
(If the steps above don't work, you will have to install the latest custom CWM recovery for your device and then boot into recovery from Step 5. And if you get errors while flashing the rom or the custom recovery then you may have to check if signature verification toggle is enabled and disabled,it SHOULD be disabled.And then repeat the flashing process.)
Hope this works . Happy Flashing!:good:
Glad to know it works for you, for people who can't gain access to recovery any other way, ^ This is the way
I'm looking to do this later today. I've done quite a bit of reading and would like a confirmation (or correction) on the steps I plan to do.
Goal:
Upgrade my Note 4 (n910v) from Android 5.0.1 to use an NSeven rom.
Here is my phone information:
Model: SM-N910V
Android Version: 5.0.1
Baseband: N910VVRU2BOG5
USA carrier - changing from Verizon service to TMobile
My current plan:
Use Odin 3 to upgrade from N910VVRU2BOG5 to N910VVRU2BPA1 using the full firmware here. Is this guide adequate for the manual update?
Once upgrade to 5.1.1, I want to root and unlock the bootloader using this guide.
After that, I want to update the rom to NSeven using the guide here.
Questions:
Are there any issues with the steps above?
Are the guides adequate? Or are the other ones preferred?
Do I need to flash to Android 6.0.1 after rooting & unlocking the bootloader prior to using NSeven?
Thank you for taking the time to read and hopefully reply. I just want to be sure I have the right idea before I get started.
Sorry to bump this, but any chance someone has time for a response?

OK. I don't know about those steps, as I took a different route to get to the Nseven rom. Make sure you have the ADB/Odin 3.09 or 3.10 and Samsung drivers already installed on your PC. You might want to get/DL Kingroot.apk aswell.
Step 1.
Download the 5.1.1 BPA1 full firmware, this should be a all in one file. None of these separate files eg.BL AP CSC..
"I downloaded this from Sammobile"
Step 2.
Open Odin and add the firmware file to the AP tab by clicking on it and navigating to where file is located. This takes a little while to show as Odin checks the file before adding it( Make sure Auto reboot and F.Reset Time are ticked)
Step 3.
Make sure you have unlocked "DEVELOPER MODE" and "USB DEBUGGING" is ticked before powering down your phone and putting it into download mode by holding the 3 keys Vol Down,Power,Home then Vol Up to continue, once your in DL mode connect to PC. There may be a little pause as your PC may install further driver files before Odin recognizes you phone and adds it under "ID;COM". Once your phone has been added into the ID:COM you can go ahead and press START. Allow Odin to do its stuff and once your phone reboots you can unplug from the PC.
Now you should be on the 5.1.1 BPA1 firmware.
Allow your phone to boot completely, you can skip the whole setup process but you'll need to be connected to WiFi for the next process.
GAINING TEMP ROOT.
Step 1.
Transfer the "KINGROOT.APK" to your phone and install but don't open it yet.
Step 2.
Unlock Developer Mode again and tick USB DEBUGGING. * This is necessary for ADB.
Step 3.
Open Kingroot and allow it to check for root this can take awhile just be patient. Once it throws up the results it'll ask if you want to try "TRY TO ROOT". click on the tab and watch the process. " Your phone will reboot a few times during the process" I just reopened Kingroot each time it did until the process was done. ******You'll have to repeat this process again***** as your Phone reboots while your pushing the command file through ADB. Losing root in the process.
Now that you've repeated the process again and you have gained TEMP root. You can confirm this with "ROOT Checker" you can reconnect your phone to your PC.
Step 4.
Make sure you have the "Samsung_unlock_n4-fix script file in your FASTBOOT folder located in the extracted files of ADB.
Now open a ADB command window *Open this in the same folder where you exacted ADB. to do this hold Shift and click Right mouse button on any clear area of the ADB folder and scroll down to "Open command window here"
Step 5.
Within the command window type "CD Fastboot"
To confirm your device is added type" ADB devices"
You should see a random number listed under "List of devices"
If you do your set to go.
For this next step its best you have the Notepad open with these commands to make it easier. ****COPY & PASTE*****
The commands are.....* without the numbers in front of it
#1. adb push samsung_unlock_n4-fix
#2. adb shell
#3. su
#4. cd/data/tmp/
#5. chmod 777 samsung_unlock_n4-fix
#6. chown root. root samsung_unlock_n4-fix
#7. . / samsung_unlock_n4-fix
OK time to push the file. Start with the 1st command and press enter. Then the 2nd and press enter. Then the 3rd and press enter. Then the 4th, then the 5th and 6th then the 7th.
Now once you've enter the 7th command you'll be presented with a warning just type YES ****USING THE SHIFT KEY WHILE DO SO****** and wait while the process completes. Your phone will reboot to confirm the process is complete.
******NOTE*******
Your phone will reboot but reboot into a Bootloop, don't worry just pull the battery and memory card. Replace the battery but not the memory card. Reboot into DL mode to confirm that you are now in/a Developer Mode.
**********CONGRATULATIONS YOU JUST UNLOCKED THE BOOTLOADER********
*****NOW HERE COMES THE STINK PART*******
You'll need to flash the N910VVRU2BPA1_N910VVRU2CPD1 full firmware with Odin this will update the Bootloader to CPD1 required for Nseven to boot. But in doing so will LOCK the bootloader again. ARRRGGGGG!!!!!!
So.....
Step 1.
Put your newly unlocked phone into DL mode again and reconnect to Odin.
Step 2.
Place the BPA1/CPD1 firmware into the AP slot and press start
Disconnect when the phone reboots. Allow it to fully boot/skip the setup process. ******Note you will need Mobile Data as WiFi is non usable due to the updated firmware.
Step 3.
Reformat your memory card using your PC and place back into your phone, reconnect your phone to PC and transfer ROOTKING.APK over again.
Step 4.
Turn on Mobile data. Install KINGROOT and open, follow the same process you did to unlock 5.1.1. This time it may take a little longer and there's a chance Kingroot will fail to root just try again.
*It did it to me.
*There's a chance your phone will reboot when it comes to pushing the command file, unfortunately that's just the way it is. Just repeat the Kingroot process again.
Step 5.
Now that you've gained TEMP ROOT again, You'll need to run ADB and push the scripts again. Just follow the same process you did for 5.1.1 BPA1.
Even down to pulling the Batt & Memory card.
Step 6.
Now that the bootloader is unlocked, place phone into DL mode and reconnect to PC and Odin. Now again AP slot navigate to where you placed your Custom recovery.
****NOTE. I used TWRP 2.8.7.0 trltevzv.img as TWRP 3.0.2.0 Didn't work for me. And flash disconnecting when phone reboots.
********Congrats you now have a UNLOCKED BOOTLOADER and a CUSTOM RECOVERY on 5.1.1 with a CPD1 bootloader.
Time to flash Nseven. *don't forget to reformat your memory card.
To flash Nseven, just copy over the Nseven zip file to your memory card and flash using TWRP.......ENJOY.
* Note. I didn't flash anything else apart from the CPL1 Nseven
Even though I had all the files DL. Just follow the Nseven forum if you experience any problems.
Hope this helps getting you into/onto Nseven.
Hi all!!
This is for all the people who managed to softbrick (or hardbrick) their Lenovo Tab 3 8' (TB3-850F) tablets!
All you will need link, at the end of the post. I don't know for how long it will be up, but you can use it for now.
By the way.... Should you find something useful here... please hit the thanks button in the end
A. Unbrick
This requires flashing a clean stock rom. You will need:
a. stock rom for the TB3-850F (Google is you friend )
b. Sp Flashtool (you can download from their official site). From there, also download the MediaTek USB VCOM drivers and Driver Auto Installer v1.1236.00 (or any latest version).
Steps:
1. Install the windows drivers you downloaded
Note : If you encounter problems installing Windows drivers in Windows 10, google how to install unsigned drivers in Win10
2. Open the folder you extracted SP Flashtool and run it as administrator.
3. Unzip the rom file you downloaded.
4. Inside the folder of your unzipped rom file, look for a file similar to XXXXXXXXXX_scatter_file.txt
5. Load this in the SP Flashtool (click downlad tab, then scatter loading, load this file in there. It should load your rom you will see some colours, etc...
The tricky part:
Assuming you have correctly installed the drivers:
1. turn off the device (well if bricked it is turned off all ready) just make sure, and in SP Flashtool click options and 'with battery'.
2. Click the green download button on SP Flashtool.
3. Hold down the Vol down key on your device and connect it to a usb port.
4. If you see a red line and continue to yellow, all is probably good! Don't let go of the vol - button until yellow line reaches 100%
B. Root and TWRP recovery
This requires that you have or download:
a. platform tools (adb and fastboot)
b. a twrp.img (image file) for the lenovo TB3-850F copied to external SD Card and platform tools folder (google is... useful )
c. latest supersu.zip (flashable) copied to an external SD CARD
d. busybox.apk
Steps:
1. Grab tablet, go to settings ---> about tablet ---> click version number 7 times to enable developer options
2. From settings again click developer options and enable OEM Unlocking and usb debugging
3. Navigate in the platform tools folder. While holding SHIFT right click and select open commandline here (or similar)
4. Connect tablet to PC and in the command line issue: adb devices
If a weird number shows up and says device on the left you are all good to continue.
5. Now on the command prompt again issue: adb reboot bootloader
Your tablet should now reboot to fastboot (big Android, laying down)
6. Issue command: fastboot oem unlock (also check tablet screen for confirmation)
Wait a little bit and reboot your tablet. (should work with holding the power key down for a little longer than 10 seconds. If not hold down volume key and power button for the same amount of time - tested and working)
**At this point it is ESSENTIAL to leave the tablet to fully boot. The bootloader unlock triggers a FACTORY RESET which you must leave to complete and set up your tablet from the beginning.
** It is also ESSENTIAL to complete the boot and set up cycle because, after the automatic factory reset you will need to RE-ENABLE developer options and usb debugging. Once you are done continue to 7.
7. In the platform tools folder copy the twrp.img (you should have downloaded earlier, check upwards... )
8. Open the command line again and type:
a. adb reboot bootloader
b. fastboot boot twrp.img
** This will load up TWRP recovery only for this boot time.
****BE EXTRA CAUTIUS TO -NOT- ALLOW twrp to make modifications. Essential! Should you do otherwise go back to how to unbrick your tablet.
9. Choose install, and install supersu.zip.
10. Choose reboot to system and allow complete boot cycle! Essential!
11. Your tablet should now be rooted. However to succesfully flash the twrp recovery you need to have Busybox installed. Download as .apk and install it (at the time of writing this I believe Busybox 54 is the latest version).
12. Once installed back to the windows terminal and issue:
a. adb reboot bootloader
b. fastboot boot twrp.img
ONCE AGAIN - DO -NOT- ALLOW twrp to make modifications!!!!!
13. From you external SD Card install twrp.img, select recovery when prompted.
14. Reboot to system and enjoy!!!!
Note : Install an app that makes it easy to boot to recovery. (I personally use root essentials - Trying the combination keys did nothing for me, or just poped up the chinese options menu. That does not mean the recovery has not been installed correctly. Booting to recovery from rootessential menu, boots straight to twrp)
All you will need and credits:
https://drive.google.com/drive/fold...ourcekey=0-SDvJaXtWWk-TY9B53ct8dw&usp=sharing (thanks button, thanks button, thanks button!!! )
Results:
(it is in Greek, but you get the idea )
Hope I have helped! Happy playing with the commands and whole process! :good:
Lastly, if you get stuck at any point, you can either use this thread or PM me for further advice, explanation and/or any kind of assistance.
Note: Special thanks to @MotoJunkie01 for actually taking the time to further help people on this thread, as unfortunately I do not currently have the time to do so myself. It is worth checking out @MotoJunkie01 's threads also. There, you can find very useful and updated information.

Good guide. This tablet has temperamental steps involved with custom recovery and root. This guide gives a good outline of those steps. Here is a link to my thread for Stock Android 6.0 firmware for this tablet for members who need a stock ROM.

Thank you for the encouragement. I am in hopes that we can eventually get a dedicated device forum for the tb3-850f. I truly believe this tablet has the potential for plenty of future development.
@r&xp I love you so much, I was in the same predicament as you and you helped get my tablet running again. Just wanted to mention, I had to hold volume down when plugging in the USB for the SPFT step instead of volume up. THANK YOU AGAAAAAAAAAAIN <3

Thanks for the comment!!! :silly:
Glad it worked for you. Isn' t it like a really good feeling when you actually see your bricked device boot correctly for the first time after you had almost deemed it unusable???
(also... a... small request... could you please click on that thingy... you know... that ehhh... thanks button??? :angel::angel:)
Just an update, since damaging my TB3-850F, I have since ordered another unit from Office Depot which is due to be delivered Monday or Tuesday. Once it arrives, I'll finish my TWRP flashable stock 6.0 ROM for this device and start back on the modified stock ROM.

Looking forward to it. I picked mine up from walmart just yesterday for using as a google maps/car media center
My Lenovo Tab 3 replacement finally arrived in the mail. I'll be picking up where I left off on compiling both unmodified stock and custom stock-based ROMs for this tablet.
On my modified stock based ROM, I'm considering the implementation of Substratum (Root Ver) for theming, but I would like to get the input of other device owners first. So far, I have debloated, deodexed and zipaligned the OS. I am including the modified/patched boot image with SuperSU v2.79 SR3 binaries installed for systemless root, Nova Launcher, Pixel Icon Pack, BusyBox v1.26.2 binaries pre-injected in /su/xbin/, and Kernel Adiutor-Mod installed in /system/apps/ for user defined adjustments to the stock kernel and governors.
You guys please give me input on what you would like included in the ROM. Thanks

I had a Lenovo Tab3 that bricked during the initial set up and this saved me for having an expensive paperweight! The process worked like a charm. You ROCK!

Try again to get TWRP installed to your /recovery partition or, alternatively, try to simply boot into TWRP from fastboot with the fastboot boot twrp.img command. It is common for members to experience some difficulty in installing custom recovery on this device. It has been my experience that most members are successful the second time around.
Thanks MotorJunkie!! But mine after was saved from brick from this thread, i was rooted it also by your instructions from other thread.. Now the gps from GoogleMap doesn't determine the location (even the location already turned on ) ... Plus i couldn't check the systemupdate ( it says connection network failed even i was connecting to wifi already) ...
What should i do, or do you know how to fix it?

System updates (OTAs) won't install on rooted operating systems. To install an OTA, you must have unmodified stock /boot, /system, and /recovery partitions installed. On the GPS issue, go to Settings, Apps, and ensure Google Maps has been granted location access permission.
Hi ...
I followed this guide but during the unbricking' I unplugged the device from USB (since I could not see any input on device or indication in SP Flash Tool).
Now the device will not turn on at all (previously I would see the Lenovo Logo splash screen but then it would just stay at this screen. Now i do not see anything).
When I plug into computer by USB, it causes my computer to freeze up (Windows 10).
Any ideas or is this now completely bricked? (hard bricked).

It sounds like a hard brick. I can't speak for the OP, @r&xp on this, so you may want to get his advice. Have you tried the OP's methods of using your hardware buttons for forcing the device into adb/fastboot recognition? I think this is your only chance of recovering it. By it not powering on, from my experience, a bootloader or bootloader dependent partition has been corrupted, thus hard bricking the tablet.

Hello, I'll weigh in on this one. There are multiple threads above the TB3-850F on this forum and also another forum.
I initially followed a different thread and instructions which caused my problem. Notably do not allow TWRP write access !!! This mistake caused the soft-brick.
Anyone following any other advice about TB3-850F or downloading any other image BEWARe. Only follow the advice in this thread by r&xp:
https://forum.xda-developers.com/android/help/lenovo-tab-3-8-tb3-850f-unbrick-root-t3598727
Following this advice I now restored original image and then rooted in just a few hours.. Thank you r&xp for the good advice. :laugh:
hi folks,
tomorow should be getting my hands on the Ulephone power 2.
its the 5.5 screen 4gb ram 64gb rom.
all looks good until i have seen that the normal duel sim is one is hybrid for sdcard which is the norm right,
ant
but............
usually its sim 1 is for 4g cards and the hybrid is for 2g/3g/sdcard. yeah?
well the power 2 looks like its sim slot 1 is a 2g/3g slot and the hybrid is 4g or sdcard??????????
so will have to choose 4g or sdcard??? that cant be right?
I don't try this device with sim.
I know you can use the older power (1) have a sim 4g and SD card
So i believe the power 2 have the same method.
My first steps: How to root this device? i don't find a twrp.
I try to root with kingroot kingoroot, no results
Please?
The power 2 is the same as the power wrt the sim/memory card tray; both sim slots support 4g, but only one at a time. So if you put two 4g sims in, only one of them will have 4g (you choose which one), with a sim and a memory card the 4g should default to the inserted sim, but you might have to check this in settings.
Received my power 2 a couple of weeks ago after having it on pre-order for a month and I love it (sold the original power towards the cost).
I haven't tried rooting it yet, but was thinking of trying to flash twrp for the original power and seeing if that works. The great thing about these phones is that they're very hard to brick as you can always flash them as long as they still switch on.

I'm sure it's not working the twrp from the power (1).
If you have troubles with bootloops you can flash again the facatory rom and SP flash tools.
Press the power volume + and - and SP flash tools gonna flash.
The only way is to made a twrp from the k6000 http://fvknl.pro/k6000-plus-root-guide/
I don't know how, that device is almost the same...
There has been 2 ulefone Updates since launch
Android 8.0 is scheduled for end of the year.
Updates are fine, who can create a TWRP? So we can finally root the device

TWRP please!
Not so easy to do it. It will take very long time to port or build twrp
It sucks that power 2 still doesn't have root or twrp. I refuse to touch unrooted phones. I just received it as gift. I will keep it in a drawer and check next month or so.
I find that it lacks optimisation, kinda laggy in 3D/games ..
On Antutu, scores is 44000. I tested a galaxy S5 of a friend, it was 72000. For a phone that is several years older than Power 2.
I understand that it comes not with high end cpu/gpu but still..
I will copy my post from needrom website.
I have successfully rooted my two Power 2 phones. I had to port the TWRP recovery from Oukitel k6000 plus using Carliv Image Kitchen and following some online tutorials.
The only issue is, TWRP is semi functional, that is, touch doesn't work. I had to connect a mouse to my phone via OTG usb port and using some dongle to make USB smaller to fit the port. Also it comes with Russian language as default, but can be changed to English or any other as the original TWRP from Oukitel k6000+ (3rd button from second column, then click on Globe tab at the top right then choose English and the only button at the bottom to accept the change).
I am trying to fix this with no luck so far. But at least I am rooted and I was able to flash "SR1-SuperSU-v2.82-SR1-20170608224931.zip" which is the latest as of writing this. SuperSu functions properly and I am able to use AdAway.
If anyone is interested in the recovery image, I will post it. I flashed it using fastboot though after unlocking the bootloader using "fastboot oem unlock"

I would very much like to give this a go with my ulefone power 2!
Here you go, TWRP for Ulefone Power 2
What you need to do before you start flashing:
0) You need to have ADB installed on your computer, if you have Windows, the easiest way is by using 15 Seconds ADB Installer v1.4.3.
1) Your bootloader must be unlocked, otherwise flashing recovery will fail using fastboot command. PLEASE NOTE: When unlocking the bootloader, your phone will do a factory reset automatically, so backup all your important files beforehand.
To unlock the bootloader:
a) Go to Settings -> About Phone -> Build number (tap on it 7 times to unlock Developer Options) -> Tap on back to Settings menu then Developer Options.
b) Now move the slider for "OEM Unlocking" to enable it, say yes to the warning message.
c) Enable "USB Debugging"
d) Connect your phone to your computer via USB cable, say Yes for the dialog on your phone to trust your computer for debugging using USB.
e) Run command prompt and type
Code:
adb reboot bootloader
Then press enter
f) Once in bootloader, type
Code:
fastboot oem unlock
Then press Volume UP on your phone to allow OEM Unlock. It shouldn't take long, just few seconds and a message will appear on command prompt saying success or OK.
g) Type
Code:
fastboot reboot
To reboot your phone, it might reboot twice, it will do a factory reset and you will have to "Enable Developer Options and USB Debugging" again. As a side note, you will also notice that OEM Unlocking is grayed out. It will remain like that unless you do "fastboot oem lock" or erase the entire phone (might erase imei, but can be restored using SN Writer Tool) and/or flash bootloader using SP_FLASH_TOOL, but I digress.
2) Before you flash TWRP recovery, you must have SuperSu zip file on your phone beforehand, otherwise, your phone will not boot to Android. It has to do with something about the original TWRP for Oukitel k6000+, since the author of that TWRP port said so in the instructions about how to flash the recovery.
So download SR1-SuperSU-v2.82-SR1-20170608224931.zip from this link or the original SuperSu thread on XDA, and copy the file into your phone, say inside the Download folder in the internal memory of your phone.
3) Open command prompt again if it is not already open, type
Code:
adb reboot bootloader
4) Once in bootloader, type
Code:
fastboot flash recovery C:\TWRP-recovery-20170618-1340.img
Note: You replace the path for the TWRP recovery to where you have the file, to make it easier, just put it in the root of C drive.
Also, if you don't already know, while in command prompt, you can type C:\TWRP then press TAB to auto-complete the file name for you, so you don't have to type lengthy file names. Keep pressing TAB to cycle between similar occurrences, that is, if you have more than one file that their names start with TWRP
5) Press power button until phone shuts down. Then press Volume UP + Power and keep holding until you see super tiny text with 3 options to cycle between. Release your fingers from Volume Up + Power, then cycle between the options using Volume Up only, choose "RECOVERY" which is the first in the menu, then press Volume DOWN to select.
6) Wait a few seconds, you will be inside TWRP, connect your phone with a mouse since touch doesn't work here. Once you do, you will see a mouse pointer appear. I used a wireless mouse with bluetooth dongle, with an adapter to change USB port size.
7) Slide the slider to the right, to enable modifications to System partition. Don't press anything else, unless you know Russian, I don't .
8) To change the language to English or your own language, click on the third button of the second column. Then click on the Globe tab on the top right corner, change language, then press the only button at the bottom to accept. Language of the UI is changed.
9) Click "Install", browse for the SuperSu zip file you have downloaded to your phone, for example inside the Download folder. And then select it.
10) Slide to the right to flash SuperSu.
11) From the TWRP menus, you can reboot your phone.
12) Enjoy your rooted Power 2 phone. :good:

hello , i got a ulefone power 2 but unfortunately its not powering on. As i am from india and returning or replacing is costly and timetaking process, i need you guys to help me. I tried to flash it with software available on the website but stuck. I need some checksum.ini file which is not there in the firmware file provided. So anyone please help me. the phone doesnt even show the ulefone logo. i can just see the charging percentage when the charger is connected, then keeping it connected i tried to turn on but didnt work. keeping the charger connected ,after some time the display goes off and no mater how long you press the power button , the display doesnt show up. I can only see the notification bulb.
Soft bricked :laugh: trying to recover the phone, official ulefone guide is useless. Getting some error about a missing checksum.ini file. Will keep this thread updated
All went well until step 9, where I realised factory reset deleted the supersu zip. So I tried to reboot into system to download it again. It never booted. Doesnt even go into adb mode.
Fastboot mode and TWRP intact (TWRP needs a mouse). I was able to flash original recovery via fastboot, getting "cannot load system.img" error when I try to flash system (it appears I might need to update my adb/fastboot version).
UPDATE: was able to flash the stock rom. And tried to follow the guide again, and faced the same symptoms. If i have working TWRP, then the system doesnt boot. And vice-versa. Will keep updated, i'm a persistent mf

Yeah, I had the same issue with the software that comes from Ulefone, it was asking for Checksum Generator that I have to download separately, it was like 150kb stand alone executable, you put it in the same folder of your stock ROM and wait forever for it to build the Checksum, which unfortunately didn't work since it complains about multiple RECOVRY images. So scratch that.
What you need to do, is as I did, download SP FLASH TOOL, it works great, no shinanigans or bullsh!t. It flashed the stock ROM in less than 2 minutes (around 1:30 seconds, to be exact) and revived my phone. There are plenty of youtube tutorials on how to use it. It is easy, just load the scatter file, for the other file, you can use the same all in one mtk file that comes with SP FLash Tool (I did this) or use the one from your STOCK ROM.
I hope that helps :good:

All I can think of, you did something wrong. Initially, while I was trying to port TWRP, I had the same issue, I was trying to save some steps by flashing the recovery after I unlocked the bootloader without rebooting, the result was TWRP was not able to see any partitions.
Flash Stock-ROM and redo the steps. If you flash the preloader you might have to OEM Unlock your phone again.
I mentioned that if you "do not flash SuperSu, the system will NOT boot to Android". Also mentioned that after you unlock the bootloader, you have to RE-ENABLE USB Debugging, and while you are at it, check to see if your bootloader is unlocked inside Developer Options.
Edit: BTW, try not to unlock the bootloader if it is already unlocked. If it is unlocked, then skip the steps for unlocking the bootloader. It might cause an issue.
These are the steps I used to flash TWRP and I was able to flash SuperSu, all rooted apps are working fine, AdAway, Lucky Patcher...etc!

Apparently if you dont flash the supersu first time you go into TWRP then it gets messy. Got the root working now. Thank you for the help and of course for the TWRP build!
Also if anyone's wondering it's possible to restore the system via fastboot. Extract the rom zip (can be downloaded from http:/ulefone.com/download/power2.html ) and flash boot, recovery and system;
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
link for sp flash tool u used.
