Hi, i need help. My phone is on lollipop. I tried flashing a bumped recovery.img and i stupidly didn't realise that bumping was patched. But the phone still booted fine, I just couldn't boot into recovery. Today, I tried booting a modified boot.img and now it won't boot AT ALL! Every time I try and press the power button, it will come up with a message that says something like "security error - cause 2 boot certification verify" then the screen will just go black and the LED will flash red and blue constantly unless I pull the battery out. I am so worried!!!! If you want to know, I flashed the recovery and boot images with flashify. I am very very worried. Is there any way I can fix my phone? Thanks.

@GSYNCER, can you get to the download mode? If yes, you might as well flash your firmware using the flash tool. I hope I didn't misunderstand you.

I am not at home right now, so I can't check. But what I did do was connect a USB cable directly connected to the mains plug (no pc) and tried the download method and it didn't work. Should I try with a proper PC to see if it works? As I said, I cannot enter recovery mode or boot into the system. But I CAN do a hard factory reset, but unfortunately that did nothing I am getting very worried and I do not know if download mode works or not. I will try the download mode method when I get home.
@GSYNCER, do let me know if the Download Mode worked for you or not. I am not sure if plugging in to the mains will have the same effect as connecting to a PC. Hope to hear from you.

I managed to do it!! I managed to get into download mode when connected to a PC. Just make sure that the cable is USB 2.0 and it will boot into download mode and follow the steps in this video: https: //youtu. be/1WgXuxDbmbc (remove the spaces in the URL)
If you follow the steps in that video, your phone will be working again. I am even sending this message from my LG G3 itself! Good luck restoring. Thank you.

Hallo everybody,
I have a question for you, I have a Zuk Z2 (not the pro version) I received this morning the notification for the update to ZUI 2.0.069 and, since I have unlocked bootloader and root, the official update failed, so I downloaded the update .zip file and I installed it from the recovery (TWRP).
The installation went fine but then after the reboot the phone is not turning on anymore.
I guess the phone is not completely off because the white LED is on but when I try to turn it on nothing happen, and if I press the power button for long time I see a black screen with the ZUK logo in the middle but only for a second and then the screen return black.
Also the device is not recognized by the computer.
Do you have any idea what went rong? do you know how to fiy it?
Thank you very much!

You've bricked your phone, you can recover it with qpst tool. For instructions head over to zukfans.eu
Thank you for your answer.

So basically what I did was enter in fastboot mode and from there, using adb comand, I unlocked again the bootloader (I already ulnocked it before but the last update locked it again) and then I was able to reboot the phone succesfully.
During the soft brick of my device I was able to enter the recovery (pressing volume up + volume down + power button for almost two minutes) but in the recovery I was not able to wipe and flash a new room, so what really helped me was a tip from a guy in the zukfans.eu forum for enter fastboot directly using the phone buttons.
To do that you have first to completely turn off your phone (from the recovery for example) and then you have to press the buttons volume up and volume down at the same time and NOT the power button, at this point you connect the usb cable from the computer and your phone will enter fastboot mode.
Once in fastboot mode you can use adb comands for recover your phone.
I hope my explanation was clear and if you need I can send you the link to the dicussion at zukfans.eu.

If you have i modded international rom, that might cause your problems. Use official zuk rom, if you want international flash cm13 or another one.

hey guys and girls
I have a problem with Zuk Z2
The problem is that when the flash-in phone automatically disconnected and I have uploaded all the files you need.
The phone starts but before my eyes:
MAIN MENU:
-reboot
-install update package
-poweroff
When you select "install the update package," the message "system will now install update.zip root directory of the system partition in first ..."
Please help Someone may have a similar case? I know, I'm green: /

I do not understand what you meant when you say " The problem is that ......... file you need"
It appears that when you boot your phone went to stock recovery mode instead of normal mode. If you can not boot it to normal you might need to flash the firmware.

i installed cm14.1 today from the cyanogenmod website i had everything running fine until i reboot into recovery. i got a black screen and it didnt bot into recovery at all so i held my power button and volume down and nothing happens. i cant even boot up into fast boot or anything. nothing is turning my phone on. when i connect it to my pc nothing happens. is there anything i can do?
There's a mega unbrick guide for the OnePlus 3, use that then install the correct firmware and install the custom TWRP and re flash the ROM
i tried that method but the device doesnt even show up on my pc

Get this sorted yet? You'll need a modified TWRP recovery for the newest CM based builds. I went through the same thing yesterday or the day before. Try holding volume down and power for like 30 seconds until you feel it vibrate that it is rebooting. Then hold volume *UP* while it reboots or if you see the "your device is not safe..." flash screen hurry and press volume down and go into fastboot. From there you can fastboot flash a new recovery.
I had the same problem as well, in device manager go to ports (com & LPT) and it will show up there under qualcum device. Don't forget to go and turn off certificate verification
Thanks guys I'll try this after work. Hopefully it works. If not sure oneplus are hopefully releasing a new phone soon
No it didn't work. I have a feeling I deleted something I shouldn't have because I was clearing out my files before I restarted and that was that.
you gotta use special twrp recovery for cm14.1...
https://www.androidfilehost.com/?fid=385035244224394867
Just use the recovery rahditzz provided you with a link, if your phone is stuck on black screen with white led hold your power button until it turns off, then boot to fastboot and flash the recovery and you will boot...

Your running vista???? Good god update your OS!!
Maybe your fastboot drivers got updated? There were some reports around this. You could try reinstalling the drivers and following the unbrick guide without an internet connection.

Cool u can boot into Fastboot, what error do you get when you type Fastboot devices? Nothing shows up?
Hello community members,
TL;DR no adb, no fastboot, no flashmode, no QDloader (or similar) ... how to unbrick it?
I was trying to force Android to allow lower lcd backlight brightness levels by patching framework-res.apk and I had the edited zip file ready to flash. Then I realized that my Android 7 Ressurection remix ROM (thread) flashed Cyanogenmod recovery, which I don't like. So I decided to reflash TWRP 3.0.2 (link) ( edit: using "fastboot flash boot twrp.img", which was almost fatal mistake) and it has gone almost well. The phone started to boot into recovery mode everytime (and took a long time doing so). So I googled a bit and found this thread which lead me to this thread. I was looking forward to seeing my display brightness at lower than default values, so I probably skipped some security checks and texts with red color, so I flashed the zip with the boot.img replaced. After flashing I chose reboot and nothing happened since.
The problem is I flashed something that was not for my device (extracted boot.img to wrong mmcblk). The command that bricked my phone is (from META-INF/com/google/android/updater-script):
Code:
package_extract_file("boot.img", "/dev/block/mmcblk0p6");
After that it doesn't boot, doesn't light up LED (even when charging), doesn't get detected by PC in any state.
So I have no adb, no fastboot and no flashmode and not even a QDloader or similar mode.
Is there a way to unbrick it?
EDIT: How to unbrick it using JTAG interface? If I find somebody that has the required equipment, what data do I need to give them?
Hey there! Did you manage to solve the issue, because I just got into the same situation after the zip didn't save the corrected partitions but the initial ones... So i ended up without any signs of life in my phone

Nope, I found no solution ... even some kind of Qualcomm flashing mode via COM (serial port over USB) does not show up nowhere. I gave up and bought a used S5 mini, which is full of features I appreciate.
I'm gonna keep this Xperia M for some time if some solution comes up.

No, as I said. The partition that got overwritten was /dev/block/mmcblk0p6. It was overwritten by boot.img from LG OPTIMUS 3D that I link to in the main post.

Hello, my phone has been completely dead after switching to slot B via TWRP.
But major problem is that it is not recognized by PC, no nothing like port 9008 into device manager.
Already tried different combos, but no luck.
Tried with deep flash usb method, still no luck.
Please help if anybody has any idea or method how to bypass this situation.
Also, if anybody knows about the test points in our z2 force please please provide us, Thanks!
If we successfully deal with this situation, many many major problems will be solved or dealt with ease on xda regarding our device.

Accidentally flashed the wrong blankflash (so I can't flash Android) and I didn't find any way to put the phone back to EDL mode... Only Lenovo/Motorola knows...
Yep, I'm having the same issue. I was on Stock Oreo, and tried to OTA to Pie (my phone is RETBR), OTA was detected and download, but the install fails every time, seems to be an error with partition B (logs are above), so I intended to flashall the slot B to "correct" the partition, but as soon as I marked B as active and rebooted to bootloader again, the phone didn't startup anymore, and nothing is reconized on PC.
Anyone got any progress on this?
