[Temporarily] flash TWRP recovery on smartwatch without hardware buttons vol up/down - Other SmartWatches

Hi all,
I've ran into a problem while attempting to flash TWRP recovery to my Lemfo LEM8 watch. When I boot into the bootloader I found out that it is still locked so I tried unlocking the bootloader by executing the command: fastboot oem unlock. Now the problem is that in order to actually unlock the bootloader I have to press the vol up button which is a problem since the Lemfo LEM8 doesn't have any volume buttons....
The reason why I want to unlocker the bootloader is because I want to temporarily boot into TWRP recovery, why temporarily? Because I am not sure I succesfully ported the TWRP recovery for my watch and I don't want to brick the watch with flashing a faulty recovery.
I know the tool: flashtool which can also flash the recovery to the device ofcouse but I rather temporarily boot into the recovery instead of permanently flashing it with flashtool.
Steps I took:
HTML:
adb reboot bootloader
fastboot devices
0123456789ABCDEF fastboot
fastboot oem unlock
....
So my question for you guys is: does anyone know how to simulate a volume up key press so I can unlock the bootloader?
Any other suggestions on how to install the recovery are welcome aswell ofcourse!
Thanks in advance,
Kasper

You do not need to unlock the bootloader on a LEM8. It does not actually validate the contents of anything you flash into recovery at all. Use SP Tools (flashtool, as you mentioned) to flash recovery (and/or system and boot if you like). You will need a scatter file specifically for the LEM8, which is available around the 'net. If your custom TWRP does not work, just flash the original recovery back in. (Make sure you extract the original recovery first, also using flashtool, or pull it out of the most recent firmware image if you choose to download one.) As long as you use the right scatter file and only replace recovery, you will not brick the watch. You might get a boot loop, but that's easy to fix by simply reflashing the original recovery.

I am in the same position. I think I have both root and TWRP but cannot load them in to test.
From what I have found is that the command "fastboot oem unlock" is only used with older Android ROMs and you need to go into developer options and turn on OEM Unlock.
You then issue the command "fastboot flashing unlock" so that you can then flash the twrp recovery image by issuing the command "fastboot flash boot recovery.img" or whatever you named it.
The problem is that the command "fastboot flashing unlock" results in a warning message on the watch screen that requires you to tap an accept radio button or similar. Unfortunately this radio button is hidden behind the curved screen at the bottom and you cannot use the round to square screen found on the turn off screen to bring it into view..
Edit: On a closer look with a magnifying glass when I retried it asked to push the volume button up, but since there are no volume buttons on the device then ???????
If anyone has a solution, I would be grateful.
I used Magisk to patch the boot.img to give root and Team Hovatek's Mediatek Auto TWRP Recovery Porter to incorporate TWRP into the recovery.img.
I have tried the SP Flashtool in many configurations without success. The watch simply refuses to reboot and I have to use SP Flashtool to flash the stock ROM back on it to get it to work.
Any help would be appreciated.

Register and download your firmware; the scatter will be in the extracted download.
Or create one using the likes of WwR_MTK
Also, for the volume up issue - have you tried connecting a USB keyboard to your watch using a USB to Micro USB adapter? Long shot but never know? I've connected a mouse before and it worked. However Android had already booted and loaded the GUI so not sure about the lower boot level drivers etc

Doogee X5 Max Pro Root Recovery OTA

******************Root Recovery Doogee X5 max pro*******************
Your waiting Time IS Now Finished Here is Complete Guide to Root Doogee X5 Max Pro install twrp And More,
Hit :good:
ADB & Fastboot
Before doing most things mentioned below you will need "adb" and "fastboot" installed. Two of your options are to install the Android SDK Tools or the Minimal ADB and Fastboot tool. If you are somewhat new to this I highly recommend the second one. Go here, download the latest version (1.3.1 as of this writing), and install it. When setup is complete you should have an icon for the Minimal ADB and Fastboot tool.
Note: I highly recommend you add "C:\Program Files (x86)\Minimal ADB and Fastboot" to your PATH variable in Windows. This way you can open a Command Prompt anywhere and use adb or fastboot.
1) Unlock Bootloader
Power on the phone and skip through all of the setup options
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly
Type fastboot oem unlock
Press Volume Up to say Yes and wait for this to finish
Type fastboot getvar all and look for (bootloader) unlocked: yes
Type fastboot reboot
You should see your phone reboot a couple times as it erases the phone
Install twrp-
Power on the phone
You can configure your phone now or just skip through all of the setup options and do that later
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt to wherever you extracted the .img file
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly, rename twrp to recovery.img
type fastboot flash recovery recovery.img to flash recovery
Type fastboot reboot
Rooting-
Download BETA-SuperSU.zip and save it to the phone's internal memory or an inserted microSD card
Plug the phone in to your PC
Open a Command Prompt
Type adb reboot recovery
You should now be in twrp. Go to Install zip, find SuperSU.zip, and install it
When it finishes go to Go Back -> Reboot Phone -> No
Once the phone boots up launch SuperSU and configure it as you like
Other Solutions-
i have doogee x5 max-s (i geuss limited editon in algeria ) with mtk6735 . i do evrything and all steps but when i reboot to recovery mode i have ( no command ) in the screen .... how to fix that ? sorry for my ****ty english XD
I had the same Issue but i have found a solution!
After you have flashed the twrp recovery, dont reboot the phone! the "recovery.sh" will replace the twrp on every boot!
Just pull off the battery after flashing, disconnect usb and put the battery back in to the phone.
Now get in to the recovery by pressing volume up and power button together until the select bootmode menue appears.
select recovery with the volume up button and enter with the volume down button.
and now you should be in the twrp main menue.
i hope it works for you too!

It does not work from step 12, all the drives are correctly installed and windows recognizes the cell, the recovery image is in the internal memory and also in the sd but of the error "can not load Recovery.img". I tried all the tutorials on the net to do root and nothing worked.The flash does not recognize to pass the recovery also the installed drivers because windows recognizes the cell phone.

Flash does not pass the file in the download only option, the process does not start. I reinstalled ROM by firmware mode all ok, but the process of passing recovery on command 12 and 13 of the error message. I manually copied the recovery to the sd and internal memory but also from the error. Does not find the file speaks that it is not a command found.

Until today I could not do root on x5 max pro. In the method below even downloading the twrp when starting with the power + volume down button start with a menu in Chinese and if you start with volume up + power goes in the default recovery mode.
Same as Pitro1 I am on 16.01 update and I cannot install twrp no matter what I try.
I tried x32 and x64. I tried rebooting directly on recovery or first load system and then adb reboot recovery. I tried to format all first (now I lost my Imei and so on lol). I downgraded and updated again. Downgrading works only with 26.12 version. All others are giving me Colorado lines on the screen and nothing else...
OEM unlock, file transfer, adb, fastboot, drivers detection, are all working good. Only I cannot install twrp...
Also I cannot write nvram nor with SN Writer 2.1504 nor with Imei & SN Writer 1.7.2, MetaAP mode fails all the time...
I'm just about to send it back...

How old is your phone and what build version was it at before you started? Because this doesn't work on mine. Which of the "Android 6" ROMs did you flash to start with as I've tried flashing mine back to an earlier one in case it's something with the later stuff that my phone has come with but they either don't make a difference or they won't even boot.
I tried the method in the first post here and the phone wouldn't even boot (switch on and you get the Doogee logo in silver for a few seconds then it reboots and does the same again). I had to flash the stock ROM from NeedROM to get it working again.
I've tried flashing TWRPx32 and x64 available NeedROM both with SPFlash tools and with ADB. Generally flashing it with ADB from the command line leaves the phone in that boot-loop. If I flash it with SPFlash when you try to boot into Bootloader afterwards you get the Doogee logo in silver for a few seconds then it seems to reboot again on it's own and boot normally - you don't even get the menu to choose Fastboot, Recovery or Normal. From then on trying to boot to the Bootloader gives you the menu but choosing Recovery gives you the standard recovery.
It's almost as if something is overwriting the recovery partition with the original after I flash TWRP onto it.
Anyone got any suggestions about where I might be going wrong or a way around whatever additional security they might have put in there?
Hi. I have tried to root my x5 max pro with flash tools to load TWRP, but it always restarts normally and the TWRP does not come out. I found you and I started to try this method to load the TWRP. Does everything good, unload bootloader and load recovery, but loading the TWRP gives me error .:
Device unauthorized.
This adb's $ ADB_VENDOR_KEYS is nor set; Try adb kil-server if that seems wrong
what I do?
rooting X5 Max pro in Ubuntu 16.04
Hi all, this is my first china phone and I basically bought it only to experiment, I'm a linux power user but this is the first time I 'play' with an android OS.
thanks to multiple guides and posts on this and other forums I'm getting somewhere and learning a lot about how to manage an android OS, I'm sharing a bit of info I unovered about doing this under ubuntu but I'm also stuck and in need of guidance, please help me.
Linux specific issues:
I'm running ubuntu 16.04 LTS, installed fastboot and adb tools from ubuntu repos, with these tools and no other modification to my system I could follow the tutorial on how to unlock the OEM bootloader with adb and fastboot.
accordingly to this post about SP flash tool in linux you might need to blacklist a modem manager module in order for SP flash tool to connect to the phone, you also need to install usb development tools (package libusb-dev) and check through dmesg that your linux OS can actually properly read mediatek usb devices.
After following the above mentioned instructions (both the linux sp flash tool tutorial and the bootloader unlocking howto) I could get SP flash tool linux (multiple version) to see the phone after you connect it while SP flash is downloading the new recovery image and flash it with an ok message.
If you get stuck with a BROM error 1013 remember to start sp flash tool with root privileges.
Phone specific issues:
I can get SP flash tool to flash my phone recovery with an ok message confirmation but the phone keeps rebooting with doogee recovery and not twrp. I'm on the newest stock ROM update (20170116) as of current post date. I've been using 32 bit TWRP images from multiple sources and linux version 5.1620 of spflash tool from their website
so my questions are as following:
1) after reading other posts I think I might have to play with different versions of SP flash tool and TWRP until I get the right combination, I think I might be using 64bit spflash tool for linux to flash a 32bit rom or something like that, can anybody confirm precise version number of the stock rom, TWRP and SP flash tool that worked out for you?
2) should I try to install the whole stock ROM posted in this chinadevices thread before trying to flash only TWRP recovery? please also check the linked thread for multiple custom ROM being ported to this phone, please also note that the full stock rom this poster uploaded (it's in the "all firmware" link) contains another flashing tools with chinese instruction called MultiDownloadTool.
www.china-devices.com/forum/index.php?threads/doogee-x5-max-pro-mt6737-custom-roms.20527/
3) I don't have access to a windows installation right now, but I do have a Win10 VM under Vmware workstation 12 pro, so I could try windows version of sp flash tool, do you guys think that USB passthrough would work?

Same here. May a work around would be finding out the oem commands in fastboot. I have seen a tutorial to get them, but you have to be root: https://www.xda-developers.com/how-to-discover-hidden-fastboot-commands/
I search a simple method
Why all so complicate? I am searching for a simple way to root.
For my old Doogee X5, I discovered just
update-ROOT-DOOGEE_X5.zip
Copy the zip to the micro-SD-card
Settings -> Phone info -> Update -> menu "update local" -> choose zip from micro-SD-card.
Start update.
That's all!
Now I search for such a simple solution for my new Doogee X5 MAX pro.
I do not want any methods with "volume down power", because my X5 MAX pro has the menus after "Volume down power" start in Chinese language.

Hi there,
I just tried the first file you posted, (twrp-x32-rom), and this one works for me after all previous attempts to boot up TWRP failed. Thanks for the link !
What I had tried before:
I have a relatively new X5 Max Pro, which I ordered a week ago. I updated the firmware to the newest version (20170116) using the OTA update function.
Then I tried to flash TWRP using the files from "needrom.com" which seem to have worked on older versions of the phone/firmware, but did not work for the newer versions.
I tried 32bit and 64bit TWRP versions and flashed them with SP flash tool, but when pressing Vol+/Power the phone would not boot into TWRP recovery. Insted, when selecting "Recovery" from the boot menu, the phone would show the Doogee logo in silver, then blink once, then boot up normally. When repeating this process, then phone boots into Stock recovery, indicating that the TWRP I flashed was replaced by stock recovery.
However, I just flashed the recovery.img from "TWRP LATEST" (the first file posted by Neaw) with SP flash tools and was finally able to boot into TWRP. I installed the superSU-zip 2.79 included in the link, and I am now rooted. Once again, thanks for posting this :good:

Doogee X5 MAX! SERIUS PROBLEM......
Hello Guys i have a serious problem with my phone.....i have Malware on it and i cant uninstall it or anything alse.....the worst thing is that my phone not responding in any connection except that charging.....i can't have access on my storage cause this is not allowed or gives the choice! i tried everything but nothing nor the usb debugging or anything else please give me your help!!!!

Problem after root attempt

Hello,
I tried to root my P8 Lite, which is something I've already done on a lot of other smartphones. So I first unlocked my bootloader, then I tried to follow a guide to root it. Everything was going smooth, but when I hit enter for the last time into the command line (at this point of the process, it just installed superSU) my phone rebootd and stucked on the huawei logo. After 20mn I decided it was enough, I unplugged it and hard rebooted it, but still stuck on huawei logo.
Since this, I wasn't able to reboot my phone, nor enter the fastboot/rescue mode. Now I tried on more time to enter the fastboot, and I don't know why but after a few time it showd up !
So basically my phone is now on fastboot mode, unlocked, and I come here to seek answers about the method to flash it and start again with a fresh android. I don't even know where to find the correct rom to flash, nor how to flash, if for instance I should use adb, etc.
If someone here is able to help me, that would be greatly appreciated.
By the way, I manually updated the phone to android 6 and EMUI 4.
Thank you a lot for enlightments.
Hello! Since you are in fastboot mode you can easily fix the issue. Just download a stock rom you wanna flash and use (you can try the new B588) and with the Huawei Update Extractor, extract the boot.img, recovery.img, cust.img, system.img from the UPDATE.APP file. Then flash these in the order i wrote them (using the fastboot command for example:
Code:
fastboot flash boot boot.img
, same thing for all of these just change the file names). That is how i fixed my last 2-3 bootloops. I would suggest looking here first though: https://forum.xda-developers.com/p8lite/general/mega-thread-root-unbricking-updating-t3400994 on Chapter 4. Hope this helps and good luck
Hi,
Thank you for your answer.
Problem is now, my phone ran out of bttery so not in fastboot mode anymore and I just can't figure out how to go back in fastboot anymore.
I tried to power on the phone while pressing vol up, wait for the huawei logo and wait for ten more seconds, nothing except a black screen. I tried vol down, both vol up and down, still nothing. Thing is, yesterday I don't even know how I managed to enter fastboot, I just tried, didn't work, so I put my phone on the bed, and ten minuts later I realized it was on fastboot mode. Informatics huh.
If you have any idea on how to go back in fastboot mode, I tried using adb, but it needs the phone to reach systm to be able to reboot.
By the way you talked about a specific rom, where can I find this one ?
Thank you again for your time.
EDIT : Ok I managed to reach fastboot, what I did was to plug it on my laptop, powered off, then pressed vol down and power on, and it worked. Informatics has its reasons...
Still interested into the rom ou talked. I'll try to find it on my own though. But if you got a link, I would be happy to download it.
EDIT2 : Ok I tried to flash, everything went good, but my huawei is still in its bootloop. I extracted the B588 rom, but there was way more than 4 img files. I still flashed only the four you and the link you gave me told me, but maybe I need to flash more than these 4 ?
Try this https://forum.xda-developers.com/p8lite/general/mega-thread-root-unbricking-updating-t3400994 <-- follow the " Bootloop/Softbrick" method if you cannot install the latest firmware directly. You may need to flash original recovery first too. Any recovery version will do they are all the same, find the how too under the "install TWRP" section, but basically it goes "enter fastboot, type fastboot flash recovery recovery.img" while you have recovery.img in the same directory.
[edit]
Also, if you are on MM you should not be using a batch file to root. Once you have TWRP installed, you need to flash 2 zips via TWRP. They can also be found in the mega thread.

Single stable SuperSu v2.76 also works for builds less than b580.. For builds greater than that, use 2 zips method
Well, it obviously didn't

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.
WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.
I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help
This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too.

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:
< waiting for any device >
How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.
Thanks

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.
Thanks

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.

Nokia 5 unable to install Recovery

So I gave my IMEI, serial number and $5 to someone on the internet, and in return I got an email attachment to flash to my phone. So I did, and it unlocked the bootloader. Strangely enough, now I'm getting a stupid yellow message that my device is unlocked and can't be trusted, and it's a bit of a roundabout way to get into bootloader or recovery. One ONLY works with buttons, the other ONLY with adb.
Ok, never mind, so I tried installing both the 3.1.1. and 3.2.1 of TWRP custom recovery, but I am unable to boot into it to make it stick. On top of that, my phone now says "encrypted"? WTF?
Clearly this latest incarnation of Nokia is a bunch of asswipes, offering us Sophie's choice instead of just unlocking the damn things from the start, so there's no point in asking them for help, but I'd expect members here would be able to help?
Any ideas how to proceed? Is there a factory ROM somewhere? This is 7.1.2. by the way, I'm not interested in updating. Come to think of it, I hate this so-called "progress" with convoluted "security" and whatnot. Just give me the damn phone and go away, Google+Nokia. Stick your "features" up ya clacker.
1. Okk first you jeed to go this link and download official recovery for nokia 5 running android 8.1 oreo
https://drive.google.com/file/d/1Cl1...w?usp=drivesdk
2. Rename it to twrp and give the command to flash the recovery.
3. After give command fastboot flash recovery twrp.img. Give the command fastboot boot twrp.img
And boooom you enter in official twrp

Link broken. File doesn't exist
Try this

Err... no, not quite.
1. Your link is (was) dead, but in any case I'd be wary of installing something stashed in a private Google drive folder... Thanks, but no thanks.
2. I have several versions of TWRP, that's not a problem.
3. I know the correct commands (yours are not), that's not a problem.
And boom - no, you don't end up in TWRP. You end up in system, because it overwrites the TWRP automatically UNLESS you reboot to it immediately after flashing, and THIS is the problem.
It turns out that Nokia needs to be plugged into CHARGER, not the PC, then holding Vol+ and Power button combination will do it. It took me more than a dozen tries, but it worked in the end.
Hi, I had the same problem. I've unlocked bootloader and I successfully installed TWRP and I can go to recovery but the problem is I can't boot the system as it stucks on download mode. Can you help?
Press volume up+volume down+power button at the same time for 7-8 second.
