Hi guys, after getting my Pantech Burst, I found it very difficult to root the phone, disable 4g, and to avoid bugs in my phone after updating to ICS.
Most of these things are explained in the forums but in a vague manner without any illustration.
I am starting this topic to give a pictorial Illustration of rooting, avoiding bugs, and disabling the 4g connectivity for gaining more battery backup.
If anyone is finding any other ways for removing the bugs, feel free to add it here. I will hotlink the topic to this page. Thanks.
Scroll down to see how to do the following things

1. Updating the phone to stock ICS
Step 1: Download the updater file from https://www.pantechusa.com/upgrade/burst/
Step 2: Unzip and run the installer, connect your phone in USB Debugging mode
Step 3: Click on update, wait for about 15 minutes. Phone will restart itself with the new update.
Nb: Phone will not be recognized by the software if you are using a 64 bit version of windows because of a driver issue. You will need a 32 bit version of windows 7 or 8 for installing the update.
For getting your phone into USB debugging mode, follow these instructions.
Step 1: Click on Settings in menu
Step 2: Click on Apps
Step 3: Click on USB debugging and enable it
How to disable 4G on stock ICS

Step 5: Type "CMD" in the run window and press control+shift+enter
Step 6: Type "cd c:\adb" in command prompt
Step 7: Type "adb devices" and press enter. If your device is detected by adb, you are at half way success
Step 8: Type "adb push Superuser-3.0.7-efghi-signed.zip /sdcard/external_sd/" and press enter. CMD will show some file copy info.
Step 9: Type "adb reboot bootloader". Wait for the phone to reboot and show a white screen with fast boot written on it.
Step 10: Type fastboot boot cwm-5.0.2.7-presto.img (If you are stuck at this section, remove datacable and connect again)
Step 11: Phone will reboot to clockwork recovery. You need to select install zip from sdcard
Step 12: Browse and select Superuser-3.0.7-efghi-signed.zip and install it
Step 13: Reboot the phone
Enjoy!!!
Verified to work on stock ICS. :angel:
Please note that you need a windows 32 bit computer for doing all these. Else driver not found error can occur
Nb: All commands are to be entered without "quotes" :cyclops:
4. How to get more battery backup on ICS
Step 1: After rooting, uninstall all unwanted software from the phone using titanium backup which can be downloaded for free from Play Store
Step 2: Download any battery calibration software from Play Store (search for battery calibration, download the 1st app)
Step 3: Install and run the software after your battery is charged to 100%
Step 4: Allow the battery to discharge completely
Step 5: Charge the phone to 100% one more time and restart it
Follow these methods too. (Pointed our by another XDA Member)
1. turn the screen down to the minimum brightness (there are three levels on the Burst, the dimmest is just fine for indoor use).
2. you can use SetCPU to change the CPU behavior in terms of clocking. This can dramatically improve battery life at a cost.
3. Turn off LTE
4. Turn on WiFi and hang out in good wifi coverage areas
5. Turn off any email push notifications, change email to check every 15 minutes max during peak times
6. turn off other auto push data stuff like photo syncing and that kind of thing
7. turn off GPS unless you are using it
8. Don't power-cycle or reboot the phone!
That's it. Enjoy more battery backup on "STOCK ROM"
5. Easiest method of installing clockwork mod recovery
Step 1: Download rom manager
Step 2: Run ROM Manager, choose "Flash ClockworkMod Recovery"
Step 3: Wait for some time, allow super user confirmation
Step 4: Test clockwork mod by choosing the option, "Reboot into ClockworkMod Recovery"
Enjoy!!!

Hello all,
I have a Z2 on MM with 23.5.A.1.291 firmware. I want to root and install a custom recovery and have looked at the threads on here about it but I'm pretty confused! None of the various options seem to be up to date, or stable, or understandable.
This thread seems to be the most up-to-date, but the instructions are pretty vague, files seem to be missing, and quite a few people seem to have had problems with it.
Can anyone explain the simplest, safest way to root the Z2 on the latest firware? Or at least help me make head-nor-tail of the existing instructions...
Many thanks

Download .314 ftf (or any rootable ftf for z2)
Then search for dual recovery for Xperia z2 and download the last version
And download Xperia root kit
1. Flash the ftf file that you have downloaded
2. Root it using Xperia rootkit(usb debugging must be on)
3. Install dual recovery using your pc
Thats it now you have root and recovery
I followed the guide you linked to and everything worked perfectly! As long as all files are available, I would do this again. Be sure to follow the directions exactly and you'll be fine.
Whatever you do, DON'T try to flash Nut's Dual Recovery on MM, because you'll then be in a continuous bootloop at the Sony logo; don't ask me how I know this! ;>)

I've read through that entire thread pretty much and still haven't found clear step by step instructions :/
I've downloaded the flashtool but don't know what to do now: there is no option to 'flash' or select a file..
Surely someone out there is able to write a clear, full, step-by-step guide to root this very popular phone..?
I've rooted many different phones and installed plenty of ROMs but never found so much confusing information before!
IDIOTS GUIDE Root and TWRP
Okay, may as well do it my self...
IDIOT'S GUIDE: (for Z2 Marshmallow .291)
1. Firstly go to https://drive.google.com/file/d/0B6aEcBP7FwsWUGpQdHdvaVRCQlk/view and download the .291 kernel.
2. Then download SuperSU from here.
3. Put both these files on your phone's SD card.
4. Next download the .575 kernel here.
5. Before this can be used, you need to change it from a .zip file to a .ftf file.
- Go to the file location in the file browser.
- Click on the 'View' section in the top ribbon (Win 10).
- Check 'file name extensions' in the 'show/hide' section.
- Rename the kernel file, deleting the .zip and replacing it with .ftf instead at the end.
6. Download the Recovery for MM from here.
Extract the zip file.
7. Download the correct drivers for your phone: simplest way seems to be by installing Sony PC Companion and connecting your device.
8. Download and install 'Flashtool' from here. (The 0.9.18.6 version seems to have better compatibility).
9. Install the drivers for the flash- if you are on windows 10 or 8 you will need to turn off driver signing first:
A) Press the Windows key + R together and in the ‘Run’ box type: shutdown.exe /r /o /f /t 00
- This will take you to the advanced boot menu.
– Now make the following selections to boot into the Start Up Setting Screen: Troubleshoot > Advanced options > Start Up Settings > Restart
– Then, when the machine restarts, select number 7 i.e. “Disable driver signature enforcement”. Your machine will start with Driver signing enforcement disabled until the next reboot.
B) Now you can install the Flashtool drivers.
– Windows will warn that the driver is not signed and will require you to confirm the installation.
– Once the installation is complete, reboot the machineTo install the drivers you need to go to the Flashtool install folder (e.g. C:\Flashtool) and go in to the 'drivers' folder and run the 'flashtool-drivers.exe'.
- From the menu select Flashmode drivers, Fastboot drivers, and then scroll down and select Xperia Z2 device drivers (not sure if this last one is necessary if you've done step 7 previously, but I did it and everything worked.)
- Click install, and click okay on the warning messages.
10. Enable developer options on your phone (repeatedly tap on build number in 'About phone' in settings.)
Then make sure that USB Debugging is enabled, and in 'Security' that 'Allow Unknown Sources' is enabled.
11. Back up vital data (though you shouldn't loose anything), then power your phone off with it not connected to the computer.
12. Startup Flashtool and let it update etc.
13. While holding the volume down button on your phone, connect it to your PC.
Flashtool should respond and spew out a few lines of text ending with something like 'Phone ready for flashmode operations'.
14. Click on the lightning bolt, select 'Flashmode', and then in the next window browse to the location of the .575 .ftf kernel file you made. Select it, then click 'flash' at the bottom right. There should be more lines of text hopefully showing that this is completed successfully.
15. Close Flashtool, disconnect your phone, then turn on your phone.
16. Flash the recovery: Reconnect your phone to the PC and select MSC mode.
Go to the unzipped recovery and run 'install.bat' as administrator (if that doesn't work try not as administrator).
If the window that opens up stays on 'starting daemon...' for a while check on your phone as you may need to authorize the 'unknown source' connection from the PC.
The installation should complete with a 'press any key to continue'. Your phone should then automatically reboot in to TWRP recovery.
17. Install SuperSU: Once in TWRP go to 'Install' and select the SuperSU zip (you may need to select 'storage' and choose your SD card first). Swipe to install!
18. Reinstall the .291 kernel: still in TWRP do basically the same as for SuperSU but this time with the MM .291 zip.
19. Cross your fingers and reboot!
20. All being well you are now rooted, you can check root by installing 'Root Checker' form the play store.
21. Open a beer and relax!
(22. Install Cyberian camera!)
Please give me some thanks if I have helped you!
I will post this as a new thread as well so it's easier to find.

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)

Hi all!!
This is for all the people who managed to softbrick (or hardbrick) their Lenovo Tab 3 8' (TB3-850F) tablets!
If you find it useful, just hit thanks 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
Steps:
1. Install the windows drivers you downloaded
2. Open the folder you extracted SP Flashtool and run it as administrator.
4. 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.
**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 1: 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)
Note 2: If you encounter problems installing Windows drivers in Windows 10, google how to install unsigned drivers in Win10
I apologize for not being able to post links, but I believe the required software is not particularly hard to find.
Hope I have helped! Happy playing with the commands and whole process! I will continue to help as much as I can :good:

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, I appreciate your comment. I was really enthusiastic to read that you are working on a pure Stock Android 6.0 ROM for this device! Will definitely be waiting for that!
Thank you again!

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:
I have found a way to root the Samsung Galaxy J1 (SM-J100VPP, Verizon) without needing to flash modified, rooted firmware using ODIN. I do not know if this unlocks the bootloader. Maybe someone can reply with an answer.
1. Make sure ADB/USB debugging is turned on. Settings > about phone > tap on 'build number' seven times to enable developer options.
2. Tap back button once and tap developer options. Make sure the box next to 'USB Debugging' has a check mark.
3. Plug your phone into your PC and open up an ADB window.
4. Download and install the Hidden Menus APK attached to this post, located at the bottom of the thread. (If using ADB to install, place the APK in your ADB folder and open an ADB command window and type: adb install HiddenMenus.apk)
5. Open the Hidden Menus app and scroll until you see 'Rlz Debug UI' and tap on it.
6. Where it says 'OEM Mode', make sure 'on' is selected (tap the circle next to OEM Mode to turn it on).
7. Go to my Google Drive, download and install 'android_root.exe'. This will install an older version of KingoRoot onto your PC.
8. Open KingoRoot for PC and connect your phone to the PC.
9. At the very bottom, left corner of the KingoRoot for PC window, make sure to UNCHECK the box that says 'install recommended app'.
10. Click on root and let KingoRoot root your phone.
Replace KingoRoot with SuperSU
I don't like one-click-root apps. I don't trust them. So whenever possible, I try to find methods to install SuperSU. Below is a guide to replace KingoRoot with SuperSU. The method in this thread works and only consists of a few steps. First you'll need to go to the KingoRoot homepage and download the APK for Android and install it. Then follow the steps below:
1. Delete/Uninstall Kingouser, but keep Kingoroot. DON'T reboot your device
3. Install SuperSU apk from flashable zip v2.79 (APK provided by me, attached at the bottom of this thread).
4. Launch it, press "continue" and "normal" wait until the update is successful. (You might have to close the SuperSU app and reopen it to complete this step).
5. Reboot and uninstall Kingoroot.
Thanks everyone. I really love this little phone!
ok, so all that has happened here IS. you happened to have a samsung galaxy j1 sm-j100vpp verizon prepaid phone that happened to NEVER be updated to the unpatchable 5.1.1 and you rooted the existing firmware that we all have to downgrade to, to be able to root. And to answer your question about the boot loader.... NO, flashing or MODIFYING the firmware has nothing to do with the boot partition.
BUT. the super su replacement has caught my eye and is how i found this post. I will check the work and report back. this would be a huge step forward in creating a 32 bit custom twrp as the chipset in this phone only supports 32 bit and is why twrp (cwm similar etc....) does not work on this device. i have noticed another samsung device that has "alot" of the same chipsets but still supports 64 bit and has a promising twrp I may be able to compile as a 32 bit only recovery img. after that. its smooth sailing.
