Hi all
Just got me PoV Mobii Tablet und want to flash ModdedStock ROM.
My problem is, I cant get the Tablet into recovery mode.
I connected USB and Power and tried all keycombinations.
Home+Power on leads to "Prepare enter mmc update mode" and stuck there.
Left+Power on bringt up the same screen.
Right+Power on shows a selection screen where I can choose from "Android mass storage", ADB and "Other OS". I tried all three options and it booted to android, but my PC (win7) does not recognize it. Tried it on an other PC as well.
Can someone help?
OK, found the cause.

Hi
As many people here i've encountred a problem with fota while being using a rooted ROM (g.lewarne ROM)
Now my phone is bricked. I can't go into recovery nor Download mode. I only have the LG logo for moments with error: secure booting error!
cause: boot certification verify
When i plug my phone it is not recognized in the hardware manager. I've already installed Drivers.
All i have in the hardware manager is a new hard under name QHSUSB_BULK that needs driver.
I have just one hope to get my phone alive, by reconizing it again by my computer, then maybe i can go under download mode.
I've tried everything but nothing could work without download mode.
PS: I've made a hard reset, which was maybe a silly decision.
By the way, after installing the OTA my phone went into CWM Recovery, it was detectable by adb, i used adb to reinstall TWRP, then i used command
"adb reboot download" instead of "adb reboot recovery", then i had never seen the CWM recovery again, only the mentioned above error.
After few seconds my phone screen goes black but the phone is still on since i can see light at the corners of the phone.
and it is not reachable by adb.
It makes me crazy now.
once i plug it to the computer it gives me plenty drives to format and one drive with only one folder inside called image, only readable, with many files inside.
Could you please help me to get my phone alive?:crying:
Hi all,
My phone is bricked with following syptoms:
1) Not being recognised in download mode
2) Adb without root acess (unable to push files)
3) No recovery
Detailed problems
I have a (Korean) Lg G2 (F320s) and its stuck on bootloop. It goes into download mode with Vol + with plugging into computer but the computer doesnt recognise it as attached...no sound, nothing in device manager and no found by Lg Flashtools or Kdz updater.
When simply turning on i connect it to the PC it shows as an ADB interface device and i have ADB but no root authorization (my phone was rooted before).
Lastly when i try to enter recovery it just flashes a couple of times and goes black...back light still on. In this mode when i connect it to PC it shows up several drives and phone comes up as Qhsusb_bulk device. I read a thread using UBUNTU to repair this but it wont work for me....the PC just hangs up and Ubuntu is unable to mount the drives (Even after the settings from Dconf Editor).
Please help i have been stuck for days
Please help
Please help ppl... is there a possible solution to the problem..?? JTAG maybe??
hi!
So i've messed up my phone. I was formatting my data and as twrp was stuck for 15 minutes at done i forced rebooted my phone. after that i can only boot into twrp (not even edl mode) no matter which button combos i use. But the thing is, twrp is stuck at the loading screen. the phone is recognized in adb but it is recognized in recovery and trying to use the command "adb reboot edl" doesn't work, nothing happens.
What can i do? I was thinking about using some commands where the phone is recognized in adb as in recovery but i have no idea what to do.

Hi! When I held both volume buttons and the power I dunno in what mode I was in but while my phone was on this mode and plugged in to my PC it was recognized in device manager as ADB something (I don't remember). I was shocked when I saw that my PC would recognize the phone because no LEDs was lit (not even the red LED you get in edl mode) and also my phone would start instantly with pressing the power button, (in edl it takes about 10 to restart the phone). Anyway so I tried zadig, Qualcomm drivers and even a different pc but it would still connect as ADB something. Lastly I disabled automatic driver updates in windows and installed the qualcomm axon 7 firmware driver (Google it). After that I rebooted and my phone was now recognized as "qualcomm hs loader" something and so I could use Miflash to flash a stock firmware. Miflash would work right away though but after maybe 15 tries and lots of reboots it then worked for some reason I don't know. After that I had a stock recovery back and it was all going smooth again from there.

THANK YOU SO MUCH, after 30 more attempts, I get the xiaomi miflash flashed my device, the last thing I tried was to disconnect the phone, keep the power button for 10 seconds and then connect it. The device was recognized as "Qualcomm HS-USB QDLoader 9008" download this rom https://build.nethunter.com/misc/axon7/A2017U_B15-NEW_FULL_EDL.zip unzip it and select the folder with miflash and flash it. Miflash did not send me the "can not get hello package" message anymore. I really appreciate it a lot, without your message I would probably have kept my phone in a box and forget it. I hope all people can read this comment and solve this problem. THANK YOU

Really glad I could help
My Axon 7 is the A2017U, i had the B32 Nougat running on it and wanted to try the new lineageos 15.1, but had to unlock my bootloader first i used the toolkit like I've done in the past and was able to unlock it and flash twrp, when i try to boot it back on it goes to factory testing mode, i was able to get into twrp and i wiped everything and it stopped the problem of booting directly to FTM but after that i tried to go into EDL mode and it seemed to try to enter the mode but the red led indicator light stays on rather than doing a quick blink. its no longer picked up as a COM port, when i enter fastboot mode adb doesn't seem to work and I'm unsure what to do or if I'm out of luck. Thank you for your time and the advice and help you guys are able to provide.
use ADB
Enable ADB in developer options
use command "adb reboot edl"
Used Twrp to flash Custom ROM, EDL still not fixed

I had no OS installed, only twrp recovery and I was able to unlock my boot loader. I tried to flash Lineage-OS ROM in twrp and didn't have much luck because i would get an error code saying it wasn't compatible with my phone and had to go into the ROM files and edit the updater-script file to remove the compatibility check.
In the end I have a working phone with a custom ROM but EDL mode is still not responsive and seems to freeze my phone as soon as I press the 3 buttons to get into EDL. the notification light blink remains on so ill take it as an indicator that something is wrong with the firmware that it uses. i still want to fix it so EDL can be used but unsure how to fix it. I did some researching and was wondering if using a deep flash Engineering cable would work to fix the EDL mode and any other problems that could be there.

EDL using the volume/power button has issues with the newer bootstack (which it sounds like you're on). However, since you have an OS now do as I recommended. It will 'reset' the EDL and once done via ADB command it will work with the volume/power buttons like it did before moving forward.

Using the ADB command i was able to get into EDL mode and it was able to get a COM port. using the volume + power buttons had the same problem. Would using an older bootstack fix it?

Have the same issue as you do after installing the bootstack. but even with the adb reboot edl command my phone just restarts normally.. But my OS is working fine, is there any way?
Try to use volume up and volume down only and plugging in USB cable........

Tried everything already. Can only get to DFU mode..
So, I have a similar problem: after flashing a new version of TWRP, now Recovery doesn't start. The problem is that I haven't any OS installed and the last chance to save the phone should be reflash stock by EDL... BUT EDL mode doesn't start if I press vol UP + vol DOWN during power on... (it became black with a red light, but if I digit "ADB devices" on ADB, no devices seems connected, and in the same way it's impossible to use Axon7Toolkit). So: no Recovery, no EDL mode, no OS installed, my phone is a paperweight.
Is there a method to save my Axon 7?
Here is something to try ...
Enter edl via button combo (volup + voldn + pwr)
You should have a black screen ...
Now plug your phone into the cable on your PC/laptop ..
If your PC / laptop doesn't recognise your phone via Miflash or app you are using ...
Try tapping the power button once ...this seems to open/close the port ...
I noticed this when I was using edl mode to flash a ROM
I hope this helps

I had the same problem a few days ago. When I booted to EDL Mode the red led was instantly on but the PC recognized it somthing like ZTE Handset Device Mode.
1. You can download TWRP Treble by NFound and flash it via your TWRP. Then reboot to recovery again and under the reboot tab its possible to boot to EDL/9008 Mode.
2. You build a EDL Cable to get the device from the red light to EDL mode. Just open some usb cable and connect the green and black (all four) together, plug it in the device and press the power button
until the red light is gone and hold on two additional seconds. Then remove the cable and plug another working cable in and the PC recognize it as Qualcomm in EDL mode.
This is literally how I unbricked my device.

Thanks, I tried but this doesn't solve my problem. The strange thing is that connecting my phone in EDL mode, the phone appears in device manager as COM port, but is not seen launching an "ADB devices" command and is not seen in MiFlash too. I tried to change drivers from "ZTE device (something)..." to "Qualcomm HS-USB QDLoader 9008" and in this way, although ADB doesn't detect nothing yet, MiFlash detects a COM port, but flashing an EDL image still fails with a "cannot receive hello packet" error.
Now I ordered a deep flash cable, hope this can solve... next week I'll know if it works.

No need to order that cable... If you still can cancel it i'd tell you to do that. You made a mistake by changing the drivers, you had the "ZTE Handset Diagnostic Interface (DFU)" driver, and replaced it with the EDL driver.
This of course does not work because your phone is in DFU MODE instead of EDL. What you have to do is uninstall the device via device manager and also tick "Uninstall driver software for this device", then turn the phone off and enter DFU again, and then use MultiDL from this forum to enter EDL. After that, use MiFlash or EDL Tool, and try flashing a FULL EDL file
By the way ADB will only work on FTM mode or the recovery or on a working system. You won't get ADB on edl mode or dfu mode because they simply don't have adb working, it's normal
i never use xda but this quote thing is what i have aswell

all i see is the red light in edl, whatever i try it Always just goes to a red light and a black screen. this happened after trying to unlock the bootloader. i was in android 8 and tried to lock it, it messed it up as my Phone could not boot anymore, i flashed the stock android 6.0 or something that came with the axon 7 toolkit and it did work but when trying to unlock the bootloader as the device state suddenly was locked it broke the whole thing and i oped edl could save me but even that is broken just like what the person in the quote has
Well the only fix to get EDL mode is through test point, there's a thread of unbricking Axon 7 using test point, find it, you'll need to open your back cover to do this
This in case nothing works to get into EDL mode.
