TWRP 3.0.2 for Acer Predator 8 ported by Ruben. - If you like my work please donate here, it will also give me a boost to make more things for this device : https://www.paypal.me/RubenCraveiro
----------- -----------
IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.

New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk
2. Power off the tablet.
3. Enter fastboot mode by pressing the power button while holding down Vol -
4. Open up command prompt and navigate to the directory where fastboot.exe is located.
5. Pass the following commands:
fastboot flash boot unsecuredboot.img
fastboot flash recovery TWRP.img
6. Reboot into recovery (TWRP) and install SuperSU v2.46.zip

I stuck at step 4.
is this the directory where fastboot.exe is located -> C:\adb... I have 4 files there and 1 of them is named fastboot.
Also the files i downloaded and extracted from step 1 , do i need to put them in my device or they need to stay on my pc.

C:\adb is where my adb and fastboot commands are.. on the downloaded files from Step 1 only the SuperSU zip is needed on the tablet so that you can flash it later on with twrp, the rest you leave on pc and use fastboot to flash TWRP, unsecured boot image, etc...

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

If you flash stock rom, i think you have to reinstall stock recovery, the rom itself already brings stock boot.. after flashing stock recovery it should boot since no modifications have happend

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

That means adb drivers arent corrently installed, but i can see you have the folder with adb, all you have to now is download this(drivers): http://dl.adbdriver.com/upload/adbdriver.zip
Extract and open the software eith the tablet plugged in, it should tell of drivers is installer properly or not, and if not you can install, after installing it should work on the cmd the commands..

If you can access TWRP, do reboot to bootloader and flash Stock Rom, this method was tested Super Moderator of Coolpad Forums and it worked perfectly.
I don't know why it didn't work for you.

i cant root permannently. i rooted my device temporary .please help me
This method was tested on P2a42 4/32 and P2c72 4/64 (both smartphones has 251 firmware installed).
Please, pay attention and read carefully:
You have a risk that P2 will go from EDL (9008) mode to 900E while you make a reconnect of connected to PC phone.
If you haven't successfully returned it by yourself into 9008 state - the only way is repair service. See details on 4Th step below the short instruction.
ADB and EDL (9008) drivers have to be pre-installed on your PC.
For those, who faced with flashing firmware, gaining root, working with ADB and Fastboot commands, EDL mode on P2 and so on, here is the short instruction:
1. Wipe sp if you have root: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp .
2. Wipe secinfo via Fastboot: fastboot erase secinfo .
3. Wipe userdata via Fastboot: fastboot erase userdata .
4. P2 is connected to PC in EDL (9008) mode, make a reset via launching blank-flash.bat from blankflash folder.
5. Flash 251 firmware as for unlocked device using START script .
6. Choose region ( ####682# ) and then make a reset ( ####7777# ).
7. That's all folks! Now you have locked P2 with a region that you want. So you can set the phone as you always do.
Below there is the same instruction, but detailed and with pictures.
From Unlocked to Locked state on P2.
1. Wipe sp if you have root: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp .
On this step you can use Total Commander with ADB plugin (YouTube will help you, there are tons of videos about it).
I prefer not to use PC, if there is another way.
What I've done:
Android Terminal Emulator installed and launched.
Gave it permission to root access.
In Emulator typed su and pressed Enter.
Sign $ will turned to # , which means that further commands will be under root access.
Type command: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp and press Enter.
If all done right, so you will see: Screenshot 1.
View attachment 4358523
2. Wipe secinfo via Fastboot: fastboot erase secinfo .
Turn off P2.
Boot it into Fastboot mode - press and hold two buttons (Power And Volume -), on P2 screen you will see Fastboot mode: Screenshot 2.
View attachment 4358524
Connect P2 to PC (it is recommended not to use card readers; connect to USB which are situated on motherboard for PC, there is an exception for notebook (laptop)).
Press right mouse button and hold Shift on ADB folder, which is placed in the root of Disc C (С:\), choose "Open command line" - a CMD window will appear on the screen of PC.
In CMD window type fastboot erase secinfo and press Enter.
If all done properly, all drivers set properly, on the screen of your PC you will see: Screenshot 3.
View attachment 4358525
3. Wipe userdata via Fastboot: fastboot erase userdata .
Continue in CMD window. Type fastboot erase userdata and press Enter.
On the screen of your PC you will see: Screenshot 4.
View attachment 4358526
Close CMD window on PC.
4. P2 connected to PC in EDL (9008) mode, make a reset via launching blank-flash.bat from blankflash folder.
blankflash folder must be placed in the root of Disc C (С:\).
On PC you must hold opened window of "Device manager" with opened string "Ports (COM and LPT)".
Your P2 must be connected to PC in EDL (9008) mode.
Use P2 very carefully without further re-connections, because there is a high risk, that P2 can go to 900E mode.
P2 connected to PC, press and hold all three buttons (Power and both Volume).
Hold buttons (phone will be rebooted twice) until you will see "Qualcomm HS-USB QDLoader9008 (COM12)" in opened window of device manager in string "Ports (COM and LPT)".
You might get another number of port (not only 12Th), it doesn't matter.
The main aim is "Qualcomm HS-USB QDLoader9008..." string in device manager.
Please, be very careful, because even little re-press of button or re-connect of cable will send your P2 to 900E mode with constant vibration and blue LED.
Try to restore phone to EDL (9008) mode by pressing and holding three buttons.
If you have no luck (from 900E to EDL) - congrats, you've got a brick.
From this point you should ask for help in repair service.
Going further, if all is going right and P2 connected to PC in EDL (9008) mode.
In device manager window on PC you will see this: Screenshot 5.
View attachment 4358527
From blankflash folder launch (double click of left mouse button) blank-flash.bat: Screenshot 6.
View attachment 4358528
You will see a CMD window which shows you a reset process of your P2.
If all done properly (without any "ERROR False"), you will see: Screenshot 7.
View attachment 4358529
In the end of reset your P2 will automatically boots from EDL (9008) mode to Fastboot mode: Screenshot 8.
View attachment 4358530
I suppose that there is no need to speak about 5Th and 6Th steps, because it is a basic knowledge, that you should know, when you are going to lock bootloader on P2.
Important notice.
You have to use original or other cable that has been already successfully used in Fastboot mode with your Р2.
The simple way to check cable is to type fastboot oem config in CMD and look what info it will give to you.
For those, who have already locked bootloader, it is strictly recommended not to flash stock ROM via flashall.bat.
For flashing stock you should use method for unlocked device, so you need to use START script.
All will go right if you will flash via flashall.bat after bootloader was locked, without any errors, Р2 will be booted as usual - Wi-Fi, SIM-cards (with names of operators), IMEI's and Serial number - all will be OK ...
But!
Calling, SMS and Mobile data will not work, you will see crosses on antenna icons in Status bar (in the string of modem firmware in "About" you will see "X" instead of "R" (Screenshot 9, 10) as it was, modems region will be defective).
View attachment 4358708View attachment 4358709
You can switch on/of Mobile data from Notification drawer, but there will be no connection, only Wi-Fi will work.
I am searching for solution of this problem.
As soon as it will be ready, it will be posted here. See post #2.

All thanks addresses to https://forum.xda-developers.com/member.php?u=279908.
I've just translated it from Russian to English from 4PDA site
Good luck and have a nice day!
Remember ...backup rules.
Solution.
Your phone must be unlocked and you must already have TWRP-backups of modem (NON-HLOS) and EFS from Р2.
1. Unlock bootloader.
2. Install TWRP.
3. Restore modem (NON-HLOS) and EFS in TWRP - you will get working modem, but there might be no sound in telephony.
4. You should install modem image via TWRP for Android 6 or 7 to get back to a working telephony (for additional instructions see post #3).
Later, if there will be a method which will work without TWRP-backups and possibly without unlock of bootloader, it will be posted here.
Modem download links:
Android 6 (062): http://lenovo-forums.ru/applications/core/interface/file/attachment.php?id=75313
Android 7 (244): http://lenovo-forums.ru/applications/core/interface/file/attachment.php?id=75314
How to restore a modem.
Important notice - you need to use modem with the same OS version which is installed on your phone.
Look here:
Firmware 062 - this is Android 6.
Firmware 233 and higher - this is Android 7.
Flash this:
For Android 6 - Modem_P2_062_ROW.zip
For Android 7 - Modem_P2_244_ROW.zip
Flash modem via TWRP:
1. Download zip for OS that you need (do not unzip it, rename or choose extension).
2. Copy to the phone memory (or to external micro-SD card).
3. Boot to TWRP and act as it is shown on the screenshots ...

It is a difficult question.
I suppose, that official repair service can detect it.
Remember how you unlocked P2 at first time: you asked for unlock with internet connection and Lenovo ID, there is a possibility, that some data about it stored and can be used for different purposes.

I agree... But there are some reports on this forum suggesting otherwise.
One common report is the replacement of motherboard for bricked devices, that too for unlocked devices.

Every step which jitkr enumerated is explained by sergsinger who made this guide.

If you farther understand nothing please clearly explain what exactly.
"I don't understand" does not help in any way.

From Unlocked to Locked state on P2.
1. Wipe sp if you have root: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp .
On this step you can use Total Commander with ADB plugin (YouTube will help you, there are tons of videos about it).
I prefer not to use PC, if there is another way.
What I've done:
Android Terminal Emulator installed and launched.
Gave it permission to root access.
In Emulator typed su and pressed Enter.
Sign $ will turned to # , which means that further commands will be under root access.
Type command: dd if=/dev/zero of=/dev/block/bootdevice/by-name/sp and press Enter.
If all done right, so you will see: Screenshot 1.

Yes, as long as you are on stock rom.
I lost my signal forever when I did a nandroid backup from another P2. I've tried it all, but nothing seems to work when it comes to restoring it.
I'm a bit confused by the first posts. OP talks about locking the bootloader and post #2 and #3 say you have to be unlocked to restore the modem? I'd have thought you wanted to lock it in order to flash the modem.
To continue this process you need to unlock your bootloader.
Read the full thread before doing anything.
1. Download Platform Tools & Extract it: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
2. Copy the twrp file for your device into the extracted folder.
Latest Twrp for RN5Pro(Whyred): https://dl.twrp.me/whyred/
after downloading twrp rename it to twrp.img
3. Turn on Usb Debugging on your device and Connect the phone to the usb cable
4. Now open the platform tools folder and in the address section type cmd & hit enter
5. Type commands:
(a) adb reboot bootloader & hit enter(phone is now in fastboot mode)
(b) fastboot boot twrp.img
twrp mode is now open....just touch on keep read only(don't do anything you still now in twrp mode)
(c) adb devices (check your device is connected or not)
(d) adb shell
(e) setprop persist.camera.HAL3.enabled 1 ( be careful while typing or copy paste this line)
(f) exit
(g) adb reboot( your phone will Reboot now)
If gcam force closes then reboot your phone manually.
Done.I am not responsible if you brick your device.
#Now download GCam from below the link and install it.
In this method we doesn't flash twrp we are just boot into twrp to enable camera 2 api
Download GCam :

If you're not sure how this process is done then contact me in my email address : [email protected]
Thank You
I don't see the point in booting to twrp. All you need to do is to boot into fastboot and apply the adb commands.

Worked for me
I had to unlock the bootloader to follow this method.
First I got the system destroyed message, when I did with the bootloader locked.
Gcam that you suggested didn't work well for me. Then I used another one instead. Now everything is functioning properly.
Not working on my friends locked phone. It is showing "system destroyed".
You'll need to root and set Selinux to permissive because this will make your stock camera lag like hell
Work or not work?
Is the quality of the photos the same thing that happens with the other methods?
is it true that with this method, the quality of the camera gets worse?
the photo quality good better than stock app.
but the issue use gcam cant save front camera with hdr+ active
even with the miui 10 okay?
help

Which gcam should i use to front camera work correctly without patches on ai dual camera version ?
Front camera doesnt work with hdr on, or portreit mod, on any gcam i tried on rn5 whyred, sorry.
My Android phone (Motorola Edge) can no longer start properly after a failed system update. The message I get is: "Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device."
I've tried restarting it in recovery mode which didn't work. I've read that I may be able to install some software via USB and rescue the system but I have no idea how that's done. I've looked at some different rescue software such as Rescue and Smart Assistant (which would only let me rescue the phone which will erase all data) and Dr.Fone but the reviews aren't convincing and the unofficial software programs generally don't support Motorola phones. Does anyone know how to fix my phone without losing my data?? Any help is much appreciated.
Also; I'm in no way a developer so I need everything explained to me like I'm 12 years old.
hi, kid welcome to xda.
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.

Thank you so much for your input. Unfortunately I can't make it work. When I type 'adb devices', I get this text:
List of devices attached
ZY227HQ2BX sideload
I've attached more info. Not sure if this has something to do with "USB debugging"?
all things right,
that sideload appears because you have stock recovery {no need to worry}
you don't need to erase system, (it is like optional)
and the error ANDROID_PRODUCT_OUT....... is because as i said earlier you have to copy the path of the file not file name.
how to copy path of the file ?
well, simple on windows, open the folder in which system file is present. and again open command prompt type (remember to be in fastboot mode in mobile phone)
fastboot flash {drag and drop system file from folder to command prompt}.
it should look like (but not the same, it is an example)
fastboot flash E:/newfolder/nexus/files/system.img
tell me if you face any problem (also include screenshots like you did, great right?)
What file is the system file in this folder?

Hi again, I've spent all weekend trying to figure it out but so far no luck.
I don't know where to find the system file in the folder I downloader (see attached photo in my reply above this). I also tried making a service-batfile with guidance from YouTube but it seems my phone is locked so it doesn't work.
well sorry i was quite busy so i was not able to reply.
first thing first do you need your data
if so boot into twrp. find twrp image for your phone then use command in fastbootmode
fastboot boot and drag and drop twrp file.
after successfully booting into twrp use option to backup and backup your data in any external storage like sd card.
after that run flash all.bat inside your downloaded folder.
i will completely wipe and reinstall your firmware.
then after it again in fastboot mode boot into twrp and restore your backup that's it.
