Doogee F7 stuck in bootloop after root attempt - Android Q&A, Help & Troubleshooting

Hi,
I'm new here, so please excuse me if I am posting in the wrong category.
So I tried to root my Doogee F7 (not the pro version) using fastboot and TWRP, and it resulted in a sort of bootloop where it says:
Code:
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
And then it restarts and gives the same message again. This loop has been going on for some time and I can't stop it because the phone has a non-removable battery and I have tried every possible combination of buttons (i.e. Power + Volume Down + Volume Up).
The process I used in my attempt to root was as following:
1. I used
Code:
adb reboot bootloader
to go into fastboot. (I already set up everything like USB debugging and OEM unlocking in the developer options)
2. I then used
Code:
fastboot oem unlock
and pressed Volume Up to unlock the bootloader. All was successful.
3. I then tried to flash TWRP to recovery and I believe this is where everything went wrong. I flashed it using
Code:
fastboot flash recovery recovery.img
and it was successful, according to the command prompt:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery "C:\Users\momen\Downloads\recovery (1).img"
target reported max download size of 134217728 bytes
sending 'recovery' (12832 KB)...
OKAY [ 0.562s]
writing 'recovery'...
OKAY [ 0.213s]
finished. total time: 0.779s
4. After it finished I used
Code:
fastboot reboot
to reboot the phone and that's when it got stuck.
At the moment I am just letting my battery run out, as I have no other way of turning off the phone, and neither adb nor fastboot is working.
I don't really know if my device was even supported, but I followed the instructions on various websites stating that I should first unlock my bootloader, then flash TWRP, then flash superSU onto it, and my phone would be rooted. I used the latest TWRP image, and I think that was where I went wrong. Is there anything I can do to get my phone to work again?

Hey! i´m sorry for your phone, can you tell me any updates, is it fixed now? what happened? i am about to do the same process to root my Doogee F7 and i´m very worried that my phone gets bricked, so please, i need your recommendations.
I hope everything is alright with your phone.

Ah yes, sorry for not updating. I managed to connect my phone to my PC again using the flash tool and then I could flash the original ROM back onto it. I found the ROM by Googling for a bit tho I dont have a link. Be aware that if you do this, it basically factory resets your phone, locking your bootloader again and all. If you do manage to root your phone please contact me as I still have not managed to do so.
Edit: This process of flashing back your ROM always works as long as your phone powers on, so don't worry too much about bricking your phone. I think I've bricked my phone over 20 times trying to root it, and it worked every single time.

Hello there. I suggest that you use "fastboot boot recovery.img" than using "fastboot flash" if you are not sure if the custom recovery works (or if you just want to test/try it). In this way, you'll just boot the custom recovery temporarily (and your stock recovery is still in tacked).
For rooting your device, first you'll need a working custom recovery for your device (you used TWRP, very first if it works or compatible with your device).

Hi.How you actually managed to connect your phone to PC using flash tool if you were in a bootloop and had no access to fastboot mode or recovery?

Im interested too in your process to flash TWRP again, as i am in the same boot loop than you with a Doogee S60. I´ve waited till the battery ended, but now flash tool doesn´t recognize my phone. If i charge the battery, i get a boot loop again..

1.install fastboot drivers
2.run lelus script at the same time hold vol+ button once the script shows the OMAP device close the script and immediately put the battery back in .The LG phone will boot into S/W mode !
Make sure you write down your imei or serial number AND make sure battery is fully charged . then
Now simply use the LG software tool or the KDZ offline flasher look around the forum for how to guides

Then try enter in lelus fastboot mode, ad then flash x-loader, uloader, boot.img and recovery.img from stock rom for your device type model. Then repeat steps 1 and 2
Where can I find the lelus script?

Sorry for reviving such an old thread, but oh well...
Your procedure doesn't seem to work with my device. Just to make sure we are using the same driver packages, can you post a link to the fastboot driver you have successfully used?
My L9 is always showing this "partition doesn't exist" error message, no matter what I try. Lelus's script seems to do the job and the phone is detected as a fastboot device, and can even be detected in LG Flash Tool (using a 910K cable), but flashing will stop after a little over 2 minutes, because the phone disconnects. During all of my attempts, the screen stays black.
Any hint?

Then you need a Technician with a Octopus Box to repair your partition table...

Can you boot into recovery? We now have a custom recovery for locked bootloaders (and CM roms). If you can get into recovery, I would try some adb commands to mount the partitions.
No, no recovery. Just to make sure that I'm not doing it wrong, what is the key combination to boot to recovery?
I have also tried:
Code:
fastboot boot some_recovery_image.img
It says ok, but the phone just hangs at the black screen and becomes undetectable as a fastboot device, until I pull the battery. So, unless the some_recovery_image.img is unsuitable for my P760 (which may be!), there is something seriously wrong I think.
Or maybe I can try the same command with the custom recovery for bootloader locked phones... Where can I find it?

Your EMMC partition is wiped or fried... you really need a JTAG service or a Box like octopus because your L9 is Hard-bricked...
Thanks for your opinion. Yet, I still want to hear from others.
I'm running into more and more problems with the L9 as their me grows.
-Fastboot doesn't work under Windows 8.1 and 10, but under the now obsolete(for me) Windows 7, unlike my other devices, which are fine with Win 10.
-ADB seems to work, but requiring the device to be still able to boot.
-I always boot to recovery from within Android as long as the L9 ain't bricked. After a failed rom install, during which the sd card failed(could no longer write or be formatted afterwards, the last time stamps of files and folders were set during the failed install) I discovered a problem with TWRP(Artas182x's and Edwin's), which may have been present since a long time: Trying to invoke TWRP via keypress will brick the device!
So, if my P760 no longer boots, there's only download mode available, sort of the final line of defense.
-There's sort of a trick if even download mode fails: After a failed attempt unplug phone, force switch-off, if the phone is in brick state. Then switch on, force switch-off again, and only then attempt download mode again. And have patience while holding down the vol button, it might take up to 20 seconds for the phone to switch itself on into download mode. (A single forced powerdown will cause Fastboot NOT to work the next time)
But I'm absolutely clueless about the recovery issue, for now TWRP is semi-working, can only be accessed via Android, as long as the phone is fully working.
W/o Fastboot, I now have flashed stock rom several times and rooted it with Kingo rooter just to be able to run Flashify to install TWRP. If Flashify is the culprit for the TWRP issues, I could need a recommendation for a better working app.

Tried OMAP flasher ? It needs memory configuration file in order to work with our device
No, I didn't. I have sold the phone for spares.
Inviato dal mio LG-D855 utilizzando Tapatalk
I never needed the OMAP drivers and tools. As they are ancient, they will probably make even more problems with newer Windows versions.
I could by no means invoke Fastboot on this device with Windows 8.1 and 10, Seven worked. So you had to go for Download Mode instead to recover to stock rom, then root with the Kingo tool, then install TWRP via Rashr or Flashify, the most time consuming way to recover from the frequent bricks.
And the LG Flash Tool 2014 always needed several attempts to get the job done. The latest official recovery tool from LG works in D/L Mode, but will always download the rom image anew.

Random (Hard?) Brick

Hey everyone, so I woke up Saturday morning to a wonderful surprise, and am just getting around to letting everyone know and maybe throw their suggestions my way!
Device: Tmo LG V10, H901
Recovery: [TWRP] Recovery: V10_H901_pplus [V3.0.2-0] [08/16/2016]
ROM: [ROM] [STOCK] [H901] V10_H901_V20J_Stock_Custom_2e [08/15/2016]; V10_H901_V20J_Stock_Custom_2e-signed
Root: Systemless Instructions - How to - 08/08/2016
Xposed: Systemless Xposed, see root guide above
Friday night, I was using my T-Mobile V10 like normal. No recent modifications, no new apps, adjustments, etc... Plug it into the charger and go to bed for the night. No issues right?
I wake up Saturday and the screen is blank. The phone isn't responding to the power button, so I hold the Vol-Down+Vol-Up+Power down to reboot it.
The phone won't reboot. So I pull the battery, and throw it back in.
Phone hits the LG logo, yey!
But it never moves from the LG logo
So at this point, I try booting into Recovery (TWRP) and the phone seems to not be responding to my button commands. It hits the boot logo and never does anything else.
I tried to boot into Download mode, nothing, just sitting on the logo.
After messing with the phone, with and without a USB cable attached to my laptop, I finally get the device into Fastboot.
In fastboot, I can run commands, but since I am on V20J, I am unable to flash or boot TWRP
I was also able to get into download mode when plugged into my PC only.
So down below, I will go over all the stuff I have tried.
Modes I can enter-
Fastboot
Download Mode (USB)
Stuff I tried-
LG Bridge Update
Update says it succeeds
Still does not boot
When I reconnect LG Bridge again, it says an error occurred and wants to update again
Direct .img flash via Fastboot
Using the steps from this post
Unable to flash, FAILED (remote:unknown command) due to V20J I believe
Flash V20J .tot via LGUP
It seems to flash successfully, but the phone still doesn't boot
So I left for the T-Mobile store Saturday, phone not booting, just stuck on the logo.
They are Warrantying the phone, so I am just waiting on a back-ordered replacement now.
EDIT: The Plot Thickens....
So I thought I would fire up the phone this morning, maybe try some other updates/flashes again, maybe something will happen.
Now I cant even get into Download Mode (USB) anymore.
It shows Download Mode on the screen, then the phone just reboots.
Additionally, on first boot I received some sort of error on the screen, but it went away so fast I couldn't read it.
Now I can't get that error to come back for the life of me...
I am just so confused now. The phone has a mind of its own.
My brother had 2 V10's that did that. Replaced under warranty.
Exact thing happened to me back on pre mm.. I got into twrp after many many many tries.. Flashed an old back up and phone booted. I was able to get into the phone long enough to relock bootloader before it started the same crap... Warrantied it out and that was that..
Yikes. Making me scared once this warranty is up.... Would hate to just lose a phone randomly for no reason!

Can you plz guide how you relocked bootloader? I am rooted and using custom rom. Should I first install stock kdz and then give command via fastboot or it must be done with root? Thanks

You can relock via fastboot using the command
Code:
fastboot oem lock
Use the below command to check your current status
Code:
fastboot getvar unlocked
I believe it even says these commands on the screen when in fastboot.

Soft-bricked Infinix X657C

Still very new to the community, so please bear with me if I miss something or make any mistakes.
Trying to flash havocOS
I flashed an unofficial version of twrp (for X657, made sure to disable verity on both vbmeta and vbmeta_system), then attempted to boot into twrp, with no luck (it just ended up booting into fastboot for some reason).
I then tried to boot into fastbootd, completely forgetting i had twrp still installed, to flash havoc from there (this is where i think i messed up, i remember reading somewhere that twrp prevents this)
Now my phone is stuck looping on the infinix logo
Tried the SP Flash Tool, but kept getting this error. Which I'm guessing is because the phone keeps restarting (mainly because "Disconnected!" shows up in the console between two instances of the same error).
Any advice?

Probably you haven´t to flash vbmeta to boot to TWRP but just when you are ready to boot to system.

I meant twrp prevents booting to fastbootd, it was after trying to boot into fastbootd using "fastboot reboot fastboot" that the bootloop started, right now I can't seem to get past the boot logo.

This method doesn't work either since the phone won't stay off for more than 7 seconds.
I'm not stuck in a bootloop as in the phone powers on, then gets stuck, or powers off again
The phone continuously powers on and off and nothing I do (apart from disconnecting the battery) stops it, even then, once the battery is back in it begins looping again...

You don't need to reboot to fastbootd, and you can't apply ADB commands either, because your device doesn't allow it due to random reboots and due to USB debugging is disabled right now.

Not true, this is the whole idea of this kind of tools either through SP Flash tool or Infinix tool you just have to GET device can be detected, this tiny portion of time will be enough for the tools can start its job, once the tool started the device get attached without a way to get out of it. To achieve this, prepare ALL that you need for tool to work even press flash/download, connect device with PC and apply the right combination key,
Prepare device manager on Windows and check which status of connection it is passing through to better understand which mode is lacking of.

You are not saying till now which model your device is, assuming that the bootloader is unlocked.

Well, if you interrupted the process, that's not good at all. The only you can do is keeping trying it, if your motherboard was not damaged.

orange state problem with Infinix device x612b

ok hear me out, I'm a newbie, and I missed up, plz help
I was trying to root my device following this tutorial, I flashed twrp and vbmeta and every thing went alright without errors, I booted the phone into recovery to continue as how the tutorial said, but it gave me the orange state error and it restarted into system but now the device is factory reset, I enabled usb debugging and went on to follow this tutorial, every thing went same as before and I couldn't boot into recovery, so I decided to flash the "orange_state_disabler_MTK Only.zip" with adb and every thing went downhill from there, It won't boot to recovery, bootloader nor system, It just stays at a blank screen after the logo and the orange state message, It is recognized by adb as "recovery" and I can do adb commands but I can't boot to bootloader to flash the stock firmware, I found this thread and tried using the tool mentioned there, Faced an error, solved it and the phone still won't boot to any thing.
so, is there any way I can get out of this situation ?
TLDR / what you should know/ idk ¯\_(ツ)_/¯
- did something wasn't supposed to do
- can't boot to recovery
- can't boot to bootloader
- device recognized by adb but can't do fastboot commands
- device is recognized by MTKAuthBypassToolV25
- can't shutdown nor restart using phone physical buttons
- don't know if the below screenshots would help with any thing, but here goes nothing
You have misunderstanding, Orange State does not cause anything. That is just notification that bootloader is unlocked, nothing more. Therefore the Orange State Disabler cannot fix anything. You don't need this at all.
But it seems it destroyed fastboot. flash lk from SP Flash Tool

please explain, I don't know what IK is, and if I could flash things with SP flash tools, wouldn't I be able to flash stock firmware?
lk - little kernel. that is the partition where fastboot lives (and was modified by Orange State Disabler).
you need partition image from stock ROM and any flash tool to restore its original state.
i can't do that because i can't boot to bootloader
you don't need bootloader, only preloader or bootrom
ok turns out ima an idiot and misunderstood the entire situation , this is my first dealing with an mtk device so i thought sp flash tool is like odin and you need to be in download mode to flash things so i panicked, and didn't read well how to use the tool.
flashed stock firmware and the phone is up and running again
thanks for your help man really appreciate it and sorry for wasting your time

Question Help! My Oneplus Nord N200 5G cellphone is bricked.

I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.
There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.
