Hi everyone,
I have looked everywhere on google and have been at this for over 5 hours now. I have tried rooting my phone from 3 different PCs (XP SP3, SP2 and 7). With all of them i have managed to get the drivers for adb installed (after many problems) and got all the way to the fastboot part of the rooting.
Once i get there, i have the same problem on all 3 PCs. ADB can no longer find my phone! Following the instructions, i checked for the device before i powered it off and found it by doing abd devices in cmd prompt. The moment the device is powered off and then back on, bam! No more device!
I am at my wits end at this point and just don't know what else I could possibly do! I would be immensely grateful for ANY advice.
I did check that my device allowed USB debug so that's not it either.
Also, my phone is a Rogers phone and I have just put through the upgrade they sent this morning.
adb cant find your phone in fastboot mode but fastboot can
Try writing fastboot devices instead of adb devices
All the comands in fastboot mode start with fastboot...e.g fastboot flash xxx xxx.img
I ran into this problem as well on my attempt, I forgot to re-enable (or enable) depending on where I was at "usb debugging" which is in:
settings> applications > development > check the usb debugging box.
After that, when you do abd devices in your shell, it should surely list after that. Good luck!
edit-- woops scratch that.. sorry I just read back that you made sure of that.
Thank you for that!
Now, i see it in fastboot, but when i try typing fastboot boot recovery.img i get a "cannot load recovery.img"
Sorry, apparently i need a lot more hand holding than i though!
(this is where I am getting the instructions from HowardForums. I'd post the link but I can't do that yet on this forum...
Basically, these are the instructions i am following:
If the phone you have is an HTC Magic (no hardware keyboard), the method is pretty much the same. I modified Haykuro's zip with files that were meant for the Magic. You can grab it here:
*link*
Again, open another command prompt as steps 2, and 6-8 are entered in the command prompt.

8. fastboot reboot
enjoy!
These are pretty much the Haykuro instructions for the Dream, which I modified to apply to the Magic. The boot and recovery images were made by Amon_RA. Happy Rooting!
Just like with the Dream, the first part flashes a good SPL, the second flashes a rooted boot and recovery. The easiest way to test if the device is rooted is to open another command prompt in the tools dir and type
Code:
adb root
If it returns that adb is already running in root, then you're all set.

Am i doing something wrong?
Thanks so much!
You need to navigate to the folder where you saved your recovery.img
For example if you put it on d:/Android dev. you will need to do (inside cmd)
d: (switches to drive d
cd d:/Android dev. (changes the folder to android dev.)
and then issue the fastboot command
without the brackets of course...

Again, thank you so much! It seems I am still having issues as now I'm being told that "remote not allow".... is this a rogers thing?
Again i do apologize for all the hand-holding necessary here
yes, i am getting this <remote:not allow> message too. I was able to fix my other magic (purchased in october) via fastboot boot recovery.img but not this new one i have (purchased in Dec).
Anyone have any ideas how to bypass this block of 'remote, not allowed"?
This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
Long story, short:
For some reasons, seems like the WIPE command from TWRP and CWM recovery screw the partitions.
No partitions or microSD card can be mounted.
The tablet is now booting only in recovery mode or in fastboot mode (the screen with three icons - RTK, Android and WIPE) instead of Android.
IMPORTANT:
If your tablet reboot in fastboot mode DONT WIPE IT AGAIN! Just skip step 4.
First of all, MAKE SURE YOR BATTERY IS CHARGED!
Recharge your tablet for at least two hours.During the flashing process the tablet doesn`t charge.
Use the original Asus USB cable that came with the tablet or a high quality replacement cable. Cheap cables can and will cause problems.
Use a laptop or desktop with known good USB ports. If you have problems, try a diferent computer, some USB chips can cause troubles.
Disable the antivirus or screensaver, sleep etc...
1.Download these files:
from ASUS website: http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300TG/#support
Drivers&Tools, on the OS tab select Android
click on Utilities and download latest version of ASUS PC Sync (you will need this for drivers)
click on Firmware and download the lastest available (you will need this for BLOB file)
Minimal ADB and Fastboot: http://d-h.st/gbx
install ASUS PC Sync and Minimal ADB and Fastboot (on fastboot installer check the box that make a shortcut to desktop)
unzip the firmware file downloaded from ASUS site
you will get a second zip file, unzip this one too
the folder unzipped from the second one contain a file called blob
copy or move the folder to the root of your drive C: or D: or whatever drive letter you have
2.Installing drivers:
connect your tablet to PC
you will get a message about Windows couldnt find driver bla...bla, ignore it and keep your tablet plugged
IMPORTANT: even if you previously installed ASUS PC Sync or other drivers and Windows recognize your tablet, you still need to change the driver.
right-click on My Computer-Properties and click Device Manager
find the Asus Android device - should be with an exclamation mark on it (the driver is not installed sign)
right-click on it and choose:
Update Driver Software..., Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Have disk, Browse
go to C:\Program Files or Program Files (x86), ASUS, ASUS Android USB Drivers, Android and select android_winusb.inf
Asus Android Composite ADB interface will appear in the list of device drivers - don`t hit next yet!
uncheck Show Compatible Hardware and select Asus Android Bootloader Interface from the list, now hit next
3.ADB mode:
open Minimal ADB and Fastboot from desktop - from this point, keep it open
type: adb devices - and you should see some numbers under the List of device attached - thats your tablet
if you can`t see the tablet, try this command: adb start-server
4.Booting to "fastboot":
there are two ways to do this:
a) from adb window type: adb reboot bootloader
or
b) reset and hold vol-down (didn`t work for me, but maybe will work for someone else)
the three icons will appear on screen - NOW YOU ARE IN FASTBOOT MODE
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob
the credits for this part goes to buster99. He is the one who figured out the right commands for formatting partitions and flashing back the OS
here is his post: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
here we go, one at the time in adb window:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system x:\your blob folder\blob (here you enter the path to your blob file, must end with blob, to point at the file)
fastboot -i 0x0B05 reboot
THE FLASH SYSTEM COMMAND WILL TAKE SOME TIME
be pacient and wait until the progress bar is 100% full on the tablet and you get the command prompt back in the adb window.
After reboot, the Android is back on.
Cheers and good luck!!
A big thank you alexhosu,
several months ago that my tablet was blocked, but I still kept hope
a solution would be found. I'm really happy for you and thank you again for sharing.
Long live XDA
me too
Thanks from me too; was enjoying 5.0 (timduru) on my TF300 when I went to upgrade and idiotically managed to get into a TWRP bootloop(interrupted a format of \data and then used 'wipe' from the boot screen by mistake...)
Your solution has saved my tablet
Am now carefully reinstalling Katkiss
Thanks
This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again
Followed the instructions.. Worked well, but getting error 963 when installing/updating anything in Play Store. Seems to be related to storage permissions. Some users are suggesting using format instead of erase. What's the difference? Could that help.
I did factory reset, reflashed and used fix permissions in TWRP but no luck...

Big thanks from me.
I killed my tablet with an accidental restore to factory defaults while in cm12, an got stuck in an endless bootloader boot loop.
my tablet came back too life at the end of section 4 after adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3.
although getting adb to talk to the tablet was a fluke.
I just kept trying to send "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" while the tablet was loading (boot looping)
6 months of believing my tablet was dead, after letting CM12 do its own update thing, and now, thanks to the above instructions, I'm back online and its working with the stock rom.
Thank you so much for this. No idea why I couldn't find these instructions before, then I just gave up, back in business now!
Thanks a lot for your guide, this is what helped me fortunately unbrick my device, i was stuck in a boot loop with a broken recovery
Another tablet saved. Know your work is appreciated.
i have the same problem, the system doesn't pass the ASUS logo, i tired to log into fastboot (reset + volume down) and i was able to see the three icons but adb doesn't recognize my device. i see the drivers are correctly installed but no working adb. Any help is highly appreciated.

Did you try entering "fastboot devices" or just "adb devices"? adb wont find your device in the bootloader, but using fastboot commands should unless it truly is not connecting for some reason.

I would try moving the blob to the root of the C drive and try the 7th command "fastboot -i 0x0B05 flash system C:\blob" just to make sure sometime of file permission type issue isn't happening on the pc side. Other than that the only kind of issue I think it could be would have to be the connection with the drivers, although if erasing the partition's works fine, I don't really see what could be going on.
I followed all the steps and delete, but when loading the file update.blob I get this error:
C: \ Users \ mikel> C: \ Users \ mikel \ Android \ android-sdk \ platform-tools \ fastboot flash system update.blob
error: can not load 'update.blob'
Can someone help me out?

Hey, I know that I'm a couple years late on this. But, I was just given a Asus Transformer TF300T, and attempted to install the Kisskat custom rom. I unlocked the device with little issues. Rooted with little issues. But when it came to flashing the rom. I get his error saying that "no MD5 file found" and holds it there for a couple of minutes. Then gives me the failed install. My only option is to boot into recovery and restore the stock JB 4.2. If you could point me in the right direction, I would greatly appreciate it. I've searched the forum for someone with a similar issue, and couldn't find it. I hope that I'm not alone on this one. It would kill me to be stuck with the stock rom.
Hi i made a format data from TWRP recovery, and now i am in a recovery loop and got error of mount partitions, i can access to recovery and the screen with 3 icons, but when i plug to my pc it shows as uknown usb, i install the drivers but dosent reconose as a fastboot device, in minimal adb when i write fastboot devices the result is empty pleace help me.
Muito obrigado!
I know this must seem odd, being such an old thread and all but, after several years adding apps and changing ROMs on my wife's TF300T (my gift!) only these past weeks I had the need to search for help, after installing nougatella 7.1, which I did with success, only to stumble on endless logo loops and loading processes without conclusion. Don't get me wrong, the ROM looks great and it wasn't that hard to install but, after two weeks or so, gave me this problem and after correcting it and installing again the ROM, I got in trouble again...
After some five hours googling and trying different stuff, I finally found this thread and twenty minutes ago (around 2:AM) my ASUS returned to its (Jellybean) life!
Alexhosu, thank you so very much for such a detailed, yet easy to follow guide and, if you happen to come to Portugal on vacation and visit Setúbal, I'll have a bottle of Moscatel waiting for you!
Many thanks to Droidbound (who got me off the hook the first time the tablet went nuts!), and also Kevinthefixer, Gtanner00 and some other very inteligent, patient and thoughtful people, and all the guys who shared their difficulties and in a way helped me find the people with the fix.
For anyone interested in trying this method, I would say that it's paramount that you should stick exactly with what is asked and should pay real atention to what is the correct ROM update to download and use. If anyone needs help with translation to Portuguese, just say so.
Again, thank you so much for this!

Thanks for your help :good: and I'm sorry for my basic English, but here is another tablet saved. Your instructions were clear and my tablet is working.
I hope this information helps, based in the next link (user sszyman): https://forum.xda-developers.com/showthread.php?t=2275035&page=9
in which he recommends using the following commands too:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p2
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p8
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p1
With these commands and "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" I was able to solve my Bootloop problem.
Honestly I don't know which of the commands worked, I used all several times.
Hey All,
This is my first ever post on XDA ,So forgive me if I have not done a good job. I will try my best to provide sufficient details on how to upgrade LG urbane 2nd Edition Verizon model watch to Android wear 2.0 from Android wear 1.5
Known Issues : **********Android Pay is not working as reported by few users ***********
YOU FLASH THESE FILES AT THE RISK OF BRICKING YOUR DEVICE. I AM SIMPLY PROVIDING THEM AND BEAR NO RESPONSIBILITY FOR ANY SUBSEQUENT DAMAGE FROM FLASHING THESE FILES. ALL DATA ON THE PHONE WILL BE ERASED.
Prerequisites:
[*]LG Urbane 2nd Edition Verizon Model (W200V) for all other model you should have received a OTA by now , Please check OTA software updates on you watch.
[*]ADB tools ( Minimal is also sufficient) google for files and install in your computer , in my case I did it in "C:\adb".
[*]twrp-3.1.1.0 (twrp-3.1.1.0.img) recovery Image Copy of the file :- https://drive.google.com/drive/folders/0Bzk4DPXefDhrRzl3ckh6Uzhad1k
[*]Android Wear 2.0 OTA udpate Copy of the file :- [*]Modified file link http://www.filehosting.org/file/details/699795/lg2.zip or original file https://android.googleapis.com/pack.../af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8.zip
[*]notepad++ (to edit updater-script), You can use Notepad as well.
1)perform factory reset on your watch just to be on safer side.
**update** Few users have reported that they have faced error while flashing due to buggy USB cable and they could successfully overcome the error by holding the cable to the watch and making sure the cable is fully in contact with the watch while flashing .**Update**
2)now we need to modify the OTA update file to work with Verizon model W200V ( skip this step if you have downloaded modified zip file and jump to 3rd step)
unzip the 'af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8.zip" downloaded earlier and Browse the folder Edit file (updater-script) the file can be fount in the below path in my case."C:\ADB\af88cfbc96ad65e7b728e27c2decbdc6fb0e08e8\META-INF\com\google\android\updater-script". Use Notepad ++ and open the file and Remove 2 first rows,The file should start from "ui_print...", I used Note++ to edit the file and saved, as mentioned earlier you can use notepad as well.
Now Zip All files And name LG2.zip(Note : don't put all the files into a single folder and then zip, The zip should contain "META-INF" and other files) and place it in "C:\ADB\LG2.zip" for easier navigation in Cmd. (this file can be downloaded using above link Modified file")
3)next Connect your LG Urbane 2nd Edition watch to Computer and Enable ADB Debugging On watch (Settings-About-Tap about 8 times on "Build Number" and now go back to Setting and scroll down you should see new options "Developer Options" , Tap on "Developer Options" - and "ADB Debugging" select "Enable always from this computer" or something like that !!)
4)Now Check if your device has a connection to your computer using ADB tools
now on your computer under "Run" , type Cmd, this will bring windows command prompt.
Open Cmd in Windows and browse to ADB tools folder in my case I have placed ADB tools and all required files under "C:\abd"
Type "adb devices"
your device should show up under "List of devices attached"
Once device is found by computer we have to push the TWRP recover image to phone , To make life easy , I have downloaded all the above mentioned files to "C:\adb" folder
"adb push twrp-3.1.1.0 /sdcard/"
later boot into bootloader
"adb reboot bootloader"
Unlock bootloader
"fastboot oem unlock"
5)Now flash TWRP recovery (because we will be changing/modifying the original the OTA update file, stock recovery will fail to verify signature)
"fastboot flash recovery twrp-3.1.1.0.img"
boot to recovery to perform OTA side load
"fastboot reboot recovery"
Now you should see TWRP recovery welcome page,Allow read and write partition permission in TWRP.
6)now on your phone you should be in TWRP Main screen , press Install and you will find option to adb Sideload select that option and you will be presented with a option to wipe Dalvik and Wipe Cache , Select that and now go back to your cmd and type below code.
"adb sideload lg2.zip"
Now sit back and relax , The system will starts loading Android Wear2.0 to your verizon LG urbane 2nd edition watch (W200V) and once the process is finished , reboot to system.
1st boot will take some time , Have patience !! after all you have done ever thing right till now. (approx 5-10 mins, sometimes 15 mins)
Now your watch has Android wear 2.0 , enjoy.
Initially it might feel the OS is slow but allow the OS to settle down after that its snappy and the battery backup is also good in my opinion.
If you want to restore Stock recovery image just in case if you don't like TWRP, then
download the below targz file and extrat recovery.img file , LG Urbane 2 stock recovery image.
Link ,
enable ADB options under settings similar what we performed earlier.
1) Boot into bootloader
"adb reboot bootloader"
Stock Android wear 1.5 for LG Urbane 2nd Edition LTE(extract the file and copy recovery.img file to your folder , https://storage.googleapis.com/andr...wear-preview/nemo-mfd18l-factory-3faf6f2d.tgz (The file extension is */tgz(targz) , use 7zip application to extract the files and you will see recovery.img file .
Place a copy of recovery.img in "C:\adb\recovery.img"
"fastboot flash recovery recovery.img"
You can also Lock Bootloader to avoid the Notification at each boot.
"fastboot oem lock"
To get back to original android watch wear 1.5
if you don't like Android wear 2.0 use the below link and follow instruction to revert back to Android wear 1.5.
Stock Android wear 1.5 for LG Urbane 2nd Edition LTE , https://storage.googleapis.com/andr...wear-preview/nemo-mfd18l-factory-3faf6f2d.tgz (The file extension is */tgz(targz) , use 7zip application to extract the files.
Extract the *.tgz(targz) into your folder ("C:\adb")
Perform a "fastboot oem unlock", then run "flash-all.bat". Afterwards, you can "fastboot oem lock". This should restore you back to 1.5, where you need to take 1 OTA (from June 2016 Patch to December 2016 Patch).
Thanks All,
Missed something
Tried a thousand times. Not working **update** Looks like maybe It was just a buggy USB. I held it to the watch while flashing and it finally worked! I'm curious to hear anyone else's experiences with this cause it seems buggy but what would you expect? My apologies ty!

I'm going to give this a try soon, everything working like lte, messages+, and phone?
Almost got it working
Followed all the directions and all seemed to work ok without errors. However, on startup now the watch is stuck on the startup splash screen (the animated google logo, has stayed there for hours). Can still access fastboot but unable to connect via ADB since the OS is not starting fully.
I also tried to restore back to 1.5 but since i can only access fastboot, my only option is to sideload but wont work with the TGZ link above.
Anyone have any ideas? or the zip file I could use to sideload the stock Wear1.5?
Thanks
Just making sure !! Try force restarting the watch by holding power button.
Did you reset the watch before sideloading ?
On android wear 1.5 use 7zip and unzip the tgz file and browse the folder till you see flashall bat file and run the same in bootloader. I have tried it and it works. Let us know if your still facing issues.
Locked /data won't allow sideload.
Hi, I've installed twrp, but it fails to sideload LG2.zip as the /data can't be mounted as it is encrypted. The TWRP doesn't have a format option for the /data partition so I can't reformat it to delete the encryption. So I'm stuck in TWRP.

I had similar issue initially , had to restore back to 1.5 and then clean all the data and then sideload 2.0 back. Try that and let us know if that worked.
You are the man! That worked
Installed recovery.img bootloader, then ran the 1.5 bat file, then reinstalled twrp. /data unlocked and mounted, sideloaded 2.0. You turned my brick back into a watch. Thank you very much.

I made sure to reset before force restart and reset before sideloading. Still having some trouble with the 1.5 reset though.
In bootloader, which option to I select for flashall to work? ADB Devices can't see it and if i just run from bootloader home screen i get , <waiting for any device>. Same thing in TWRP.
Thanks again for your help
[Note for other users unfamiliar with this process & having similar problems - you'll have to unzip the source file, then unzip "output" to extract all the files... tooke me a few attempts to realize i missed a step!]

Flash the original recovery.img extracted from the .tgz file and try again it should work.
For ADB access in TWRP use sideload using ADB option .
So will android pay work now with this

I think I am having the same issue as you. I was sideloading 2.0 as instructed and I think I had a bad cable connection. I am now stuck with no wear operating system at all. When I start my phone it only stays on LG boot screen with the unlock icon on the bottom. My computer is now unable to recognize the device because I cannot get into settings to turn on ADB Debugging. If I follow the same steps as you can I sideload wear 1.5 and update via boot loader screen?

If I follow the same steps as you can I sideload wear 1.5 and update via boot loader screen?
For background, I have Verizon pixel 2 and am using a Mac.
I went down a massive rabbit hole last night reading through these forums and all the posts and was able to unlock bootloader, flash the January OTA and then root by doing the modified boot file with magisk. (interestingly enough the booting into recovery gives me red ! Over a dead Android and I could not load the OTA that way, nor did the adb sideload OTA comand work either, I had to push the extracted walleye img and then the zip file as discussed in one of the steps in some other thread here)
So anywho, in the end I now have a phone that gives me 2 errors when it reboots, one for unlocked bootloader and another for root telling me something is wrong with my phone and i should contact the manufacturer (which I read on here is normal), but my biggest issue is that my ADT alarm app doesn't work anymore (even if i check it off for hide in magisk). I feel like the root is just not worth it for me and I want to revert to completely stock image, even if it resets my phone and I have to re back everything up all over again like did when i had to do the unlocking of the boot loader.
So -- What are the steps I should take?
1)uninstall magisk from magisk manager?
2)delete magisk manager?
The above will unroot me, correct?
3)Do I push the stock boot image file onto the phone?
4) do I have to repush the latest OTA walleye image and zip file onto the phone again?
5) do I then do the adb reboot and do the flashing lock command (same command i did to unlock the boot loader) to lock up the bootloader and reset to stock?
If someone could be as explicit as possible in correctiong or validating my steps above it would be much, much appreciated.
I don't want to do any more unnecessary steps in flashing things than is needed so if I have extra steps above (perhaps 4 is not needed?) Let me know.
Thanks
Proceed with Caution
I am not an expert by any means, but can speak from personal experience. I was in the exact same situation as you. I followed the detailed steps to unlock the bootloader on my pixel 2, received similar issues, and the same prompt when the phone rebooted. All that to say proceed with caution.
My thoughts on questions 1 & 2: I personally wouldn't recommend you remove or delete magisk from the manager. When I did i had to reinstall it via twrp. My phone functioned fine, apart from the error at reboot.
My thoughts on questions 3 -5: When I followed the steps on XDA for your questions here I ended up bricking my Pixel 2 with locked bootloader from Verizon. Probably an error on my part, but wouldn't want someone else to go through the headache, hours of issues, and then an expensive paper weight.
My suggestion would be to:
1. Leave your phone as is and attempt to trouble shoot the app or apps you are having issue with
2. contact Google support on your phone and see if they would replace it
3. wait for an established method to unroot the pixel 2 here
Thankfully Google replaced my phone due to the error after rebooting, prior to me bricking it. I knew I had a replacement phone coming. So I attempted to go back to stock and that is when I messed it up.
Note sure this is exactly what you were looking for, but hope this helps you.
Dozens of posts with hundreds of pages on how to root but no advice on how to go back to stock cleanly?

Your version is Verizon which is making things more complicated. Generally when the bootloader is unlocked, you just hit flash-all.bat and then relock the phone. Given that the Verizon I'm not sure.
So you are on stock ROM with all these apks loaded ? If you go to settings, then do a factory data reset, you'll reset the phone back to stock and completely wipe the phone and return it to stock, at that point you can go into bootloader mode and relock.
Again your bootloader is unlocked, so the flash-all is your best option. If you see the red exclamation point with the error android laying on his back, you press power and up volume and toggle that and it will bring in the stock recovery which you can sideload the OTA however it may fail since you have magisk.
I bought my phone stock last year and have not rooted it or modified it in anyway. Too many problems and it only gets harder and harder as Google releases a new phone.
@mikeprius -- thank you for replying. after reading more on here, it seems like that's the way to go -- flash-all script, seems like i don't really need to do 1&2 that i wrote above as the flash-all will wipe that out by itself.
at that point i should be running the latest stock 8.1 but with an unlocked bootloader (and according boot up message screen) and i should be able to re-do the fastbook unlocking command to lock the phone back up.
(and yes, after reading even more now -- and i tried this yesterday -- i completely missed the portion about PWR + Vol Up button, that's why i think i had that issue, but still, i was able to push the update by pushing img and then the zip through).

If I were in your situation and the bootloader is unlocked, just use flash-all which has a wipe script then call it a day. I think trying to screw around even more is just a waste of time and I wouldn't even bother with the OTA, just erase and flash stock. You don't have to relock your bootloader if you don't want to, if you stay fully stock you may still be able to get OTA updates. I'm not sure if a bootloader locked is required someone can chime in as it has been awhile since I've done this, but over 1 yr ago, I just kept the bootloader unlocked, kept things stock and everything was good to go. Obviously there are security issues with an unlocked bootloader, but I'm sure you know this already
@mikeprius you keep saying reset/erase, do you suggest i re-set the phone and then flash the stock image?
i was just going to flash the stock image, i figured it already wipes the phone, and locking the bootloader would wipe it again, so what's the point of erasing all data prior?
Not to hijack this thread, but a question to add... I thought that there were kernels that would mask certain things to allow all of those apps to work, and get rid of the "problem with device" message.
Is that correct?

Just flash the stock images. It will auto reset.
Again, don't mess with anything just flash stock images, then go from there.
Also flash the newest version of the stock images out there. The pixel 2 will error if you try to downgrade any version.
here are all the steps to UNROOT and LOCK the boot loader on your Pixel 2 on a Mac (windblows users simply ignore all the "./" references).
1) download the latest ADB tools from google
2) download the latest factory Walleye image
3) unzip files from 1&2 into a common directory
4) edit flash-all.sh file and add "./" infront of every instance of "fastboot" in the script [windows users ignore this step]
5)hook up your phone to your computer in debug and file transfer mode. check that "./adb devices" loads your devide
6)type " ./adb reboot bootloader"
7) check that your device is still connected by typing "./fastboot devices"
8) type "./flash-all.sh"
===the script will run and your phone will be restored to stock, and UNROOTED. upon boot up skip through all of the setup steps and get to the phone settings as fast as you can. enable developer option, enable debug mode, set phone to data transfer ====
9) check that your phone is connect to your computer by "./adb devices"
10) type "./adb reboot bootloader"
11) check your devices is still connected by "./fastboot devices"
12) type "./fastboot flashing lock"
===== this will re-wipe your device again, you'll see the circle of death, and this will LOCK your boot loader back up again======
side note, feel free to skip over the steps where you check that your phone is still connected to the computer (./fastboot devices) if you're less paranoid and comfortable.

hey there. what is the command suppose to look like? every combination I try gives me an error:
first, I don't even enter the Fastboot command the same wayit given me an error:
Asads-MacBook:~ asad$ ./fastboot devices
-bash: ./fastboot: No such file or directory
so I try this: Asads-MacBook:~ asad$ fastboot devices
[serial #] fastboot
these are all the errors I get:
Asads-MacBook:~ asad$ cd /Users/asad/Desktop/walleye-opm1.171019.021
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: ./fastboot: No such file or directory
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
fastboot: usage: unknown command ./flash
...
Asads-MacBook:walleye-opm1.171019.021 asad$ ./flash-all.sh
./flash-all.sh: line 21: fastboot./: No such file or directory
...
how is the command suppose to look that I can edit it the right way?
"fastboot: No such file or directory" means that you didn't do step 1, step 3 on the file you didn't download, and there should probably be a "cd /<whatever the 'common directory'>" is. (I just created a directory named adb. That's good enough for me to know what it's for.)
You have to download adb and fastboot (which come in the adb tools file), unzip them to whatever directory you're going to use for flashing the phone, and cd to that directory.
Then, since you're evidently on MacOS, each command has to have ./ in front of it (that says "the current directory"). Try all that, then see what happens.

yayy! that worked!
so i had adb and fastboot in a folder (platform-tools) and i had the factory image in its own seperate folder (walleye-files). i was making the cd; walleye folder and trying to flash-all.sh there.
so i had to put the files from the walleye folder into the platform-tools folder. Then I made platform-tools the cd. now when . i could now follow all the steps from 4-12 and got the pixel 2 the way it was OTB.
thanks!
Great! I'm not a Mac expert (last time I used one was the 128K Mac in 1985), so I'm not sure how to export a path in MacOs, so I gave you the complicated way, but you got it done anyway. (If you ever find out how to add the platform-tools folder to your path, you can leave adb and fastboot in there and keep the ROMs [walleye] in their own folder, cd to it and adb and fastboot will still work.)
Recently, I successfully ported TWRP from Coolpad Note 3 Lite to Modena 2. After testing, everything works fine, on both devices. Since this device has locked bootloader, we need to bypass this by enabling fastmmi mode and factory mode to enable temporary root access and make initial backup and flashing. So, let´s get started.
Remember to read this post carefully. I am not resposible for any damage to your device. If you brick your device while flashing the TWRP you can *almost* always recover it using SP Flash Tool and YGDP Tool
IF YOU ACCIDENTALY BRICK YOUR DEVICE AND YOU WANT TO FLASH IT VIA SPFT, DO NOT FORMAT THE DEVICE IN SPFT!!! If you´ll format partitions in TWRP, that´s fine, but don´t do FORMAT ALL + DOWNLOAD or FIRMWARE UPGRADE! This will brick your device, like mine This tutorial will not (hopefully) brick it, but just in case something goes wrong, now you know what not to do.
Preparing the environment on your computer
Windows
Download ADB and Fastboot from this link
Open it
Install it system-wide
Also, install the drivers
GNU/Linux (Ubuntu / Debian based distros)
Open terminal
Type "sudo apt install adb fastboot libusb-dev" without the quotes (")
Other things, that are required
Since the file size of the recovery exceeds the maximum 8MB of allowed upload size, you can download it from DataFileHost.
Preparing the device
First, you need to remeber that this could render your device unbootable and will void warranty.
Enable developer options
Go to Settings -> About phone
Tap the build number 7 times
Go back
Go to Developer options
Make sure OEM unlocking and USB Debugging is enabled
Enabling factory mode
Open dialer app
Dial *#9527*#
Click on "DM"
You will be prompted to insert RD personnel password. Enter: 54321
Click cancel button
DM button should change colour to RED
Exit the app by clicking home button
Installing and setting up openrp app
Open terminal / command prompt
Type:
Code:
adb start-server
Type:
Code:
adb devices
Now, click on your phone allow debugging and make sure to tick the radiobutton to remember / always trust this computer
Type:
Code:
adb install
Press spacebar after the install word and drag and drop the downloaded openrp.apk file to terminal
Hit enter
After it´s done, type:
Code:
adb shell monkey -p com.yulong.openrp -v 500
Now, the fun part. ROOTING the device
But before that, BACKUP
Now, keep your phone plugged in, and do a normal reboot by pressing and holding the power button and clicking reboot
When it vibrates, press and hold the Volume down key (Vol-)
You will see these lines on the screen:
Code:
=>[Factory mode]
Code:
=>VolumeDown key is pressed
Code:
=>[fastmmi mode]
After that, you´ll see the LED turns green and "Up Down" text on the screen
Now, back to your computer, type in the command prompt
Code:
adb devices
You should see XXXXXXXXXXXXXX device listed (where XXXX... is the serial number)
Type in the command prompt:
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery of=/storage/self/primary/stock_recovery.img
and
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/boot of=/storage/self/primary/stock_bootimg.img
Flashing the TWRP Image
Type in the command prompt:
Code:
adb push (drag and drop the recovery image file here, like you did with the openrp.apk file) /storage/self/primary/
Type:
Code:
adb reboot
Press and hold VolumeDown key (Vol-) to boot to fastmmi mode
Type:
Code:
adb shell dd if=/storage/self/primary/recovery_twrp_e502.img of=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery
Type
Code:
adb reboot
Press and hold the VolumeUp key (Vol+) to boot into recovery. If you see white screen with "Recovery" text in it, congrats. Everything is working. If not, try again.
Flashing the SuperSU package
Download the zip from SuperSU website
Copy the zip over to the device, with TWRP running
In TWRP, click install, click the zip and confirm the installation.
Factory reset is not required, but you should at least wipe the cache

Hi i have a problem here. at the part to drag and drop the openrp file. When i have downloaded the file a drag it and drop it after the install word. The problem is that if I want to drop it there it will do nothing, nothing there shows or anything. Please respond.
I guess you can type the path to the installation file instead of dragging.
Hello,
Very helpful thread, my coolpad Modena 2 (E502) is now rooted.
Don't forget to disable the factory mode once everything is done, or you won't be able to access the storage to usb anymore.
Thanks.
helo, can i get help, when i try to install openrp on abd and fastboot, it printed this message "Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]"
can anyone help me on that step, so i can root my e502

Hello,
If I recall correctly (I don't have the phone anymore, just touched it once to root it at the time), you basically undo the "Enabling factory mode" step.
I think if you dial the number, you'll be back in the menu where you have the option to disable the factory mode.
Factory mode should be disabled when 'DM' is green.
Good luck
very good
Need Custom rom please

Hello, could you resend the twrp recovery file for this phone again?. old links not work!.
(sorry for my bad english)
