[SOLVED] Please help me guys, phone won't boot up - G2 Q&A, Help & Troubleshooting

Hello everyone, I am hoping to get some help here as I think I really screwed up my device... (D802 International variant, 32GB)
I try to describe everything as detailed as possible:
I was on the newest Cloudy G2 2.2 ROM with KK basband and it was working fine.
Now I wanted back to crDroid so I decided to put a backup onto my phone (of crDroid) and restore it. (I overwrote the .twrp file in that process)
I must have forgot to wipe before restoring the backup and now after the LG boot logo an error message in the top left corner appears stating:
"boot certification verify"
Secure booting error
cause: "boot certification verify"
Seriously guys, I don't know what to do. I tried to enter download mode but windows did install the drivers and gave me plenty notifications of formating drives... I am really lost. Please somebody help me if possible...

Enter Recovery mode and reflash...

Thanks for the reply but recovery mode is not accessible anymore. I've basically tried every button combination and I am not able to enter download mode either...
EDIT:
I fixed my phone! For everyone experiencing the same issue here is what I did. Please read the OP for a detailed description of the problem:
At first, watch the beginning of this video and check which type of brick you are experiencing.
https://www.youtube.com/watch?v=hQVTc2m6U-I
If you checked and you are a person having to deal with the quSUSB_BULK type of brick read the following post and watch the following video for clarification on what to do.

https://www.youtube.com/watch?v=_d5b_osUTug
After following the steps you should be able to access download mode and following this thread (http://forum.xda-developers.com/showthread.php?t=2432476) you should be able to flash the respective firmware for your device.
I hope that this tiny little guide may help someone and thank you for any support.

[Q][SOLVED] Bricked ZTE Libra

Hi! I have a bricked ZTE Libra (Sapo A5 in Portugal) and no mather how much I search for solutions I only seem to make things worse, so I was hoping someone here could help me.
Things started to go wrong after flashing a CyanogenMod rom. Everything worked except two things: I couldn't use anything that required my SIM card (so no phone or messaging) and I could not access the recovery screen (clockworkmod).
Without the recovery screen, I turned to ROM Manager but since it uses clockworkmod to do its work it didn't help.
Then I started trying other ways to recover my phone, until I tried ADB which allowed me a shell in my android. But then I broke it all by doing "wipe system" which cleaned my system of everything that was still working and left me with an expensive brick.
Now all I can do is boot until I see the green droid. If I don't press the volume buttons it goes into "device" mode and I can see it listed under "adb devices" but have no idea what to do with it.
If I press the volume button down to go into recovery mode it keeps flashing but never really goes anywhere.
If I press it up to go into the bootloader it stays the same and the only thing I can use to tell me something is different than the normal mode is that lsusb reports the vendor as "Google Inc." instead of what it reports in normal mode: "ONDA Communication S.p.A.".
With this I'm not even sure if I can get to the bootloader or not, but even if that is the bootloader, I have no idea what to do with it that might help me recover my phone.
By the way, I'm trying all this on Linux, although I could try solutions in Windows if required.
Can anyone tell me what can I do in this situation?
Ok, maybe my first post wasn't that easy to answer, so I'll make a simpler question to see if someone can help me.
What can be done at my android's bootloader? What is it for and what tools do I need to use to do it?
You could try installing ClockworkMod recovery using wbaw's guide here http://forum.xda-developers.com/showthread.php?t=1319257 Once that's installed you should be able to flash a new rom with it.
In bootloader mode you can flash a new kernel or recovery image using fastboot.
If you follow that guide that I wrote & Amphoras linked to then you should be able to get a working clockworkmod installed and then you can use that to flash a working rom, or restore a backup.
Thank you both, I'll try what you said as soon as I can and then I'll let you know if it worked!
Ladies and gentleman, today a miracle happened, my ZTE came back from the dead!
Apparently the problem was that I installed some GEN2 applications on my GEN1 model.
I found this while reading the tutorial you suggested, after which I upgraded my ZTE to GEN2 which allowed me to slowly recover everything else.
So, I have to say, thank you very much, and I hope I won't need your help again anytime soon! xD

You need to flash your phone's original Jellybean (4.2) firmware, it is the only way that worked for me.

Bricked | No Download Mode | Please help!

Hi
I have a LG G2 running CM12 which I just tried to encrypt (about to sell it). For some reason though the encryption failed, which I've never seen before. I had full battery and the charger connected.
Anyway, it presented me with the only option of resetting the phone. I clicked yes and now I'm in some sort of bootloop. The "teamwin"-logo for TWRP is presented on the screen for a couple of seconds, before it goes black for one second and then back to the teamwin-logo etc.
I don't care about the data, but how can I fix the phone back to CM12? Please help me!
See Edited post below
I managed to get it back to stock with LG Flashtool, rooted it and installed TWRP using AutoRec. Booted in recovery mode and got an error:
"assert failed: run_program("/system/bin/loki.sh") == 0
E:Error executing updater binary in zip '/usb_otg/cm12-20150612-NIGHTLY-d802.zip
Error flashing zip
After this I can't boot into the phone, it says "Security error" under the LG logo. After this happened I went through the same process with LG Flashtool and tried again, unfortunately with the exact same result. I've tried different ROMs aswell. Can someone please help me sort this out?
After hours of trying I finally sorted it out. If anyone runs into the same problem this helped me:
- Flash a stock KitKat-ROM using LG Flashtool
- Root using LG OneClickRoot
- Download AutoRec for Kitkat-apk from the web (not available in Play Store anymore)
- Run AutoRec for Kitkat and let it install TWRP
- Download and flash some CM11-ROM
- Check to see that all seems fine
- Download and flash the CM12-ROM you want + gapps
- Hopefully you'll run CM12 just fine again
That did it for me, not sure that every step is essential but might as well try it.
Okay... My phone was working just fine, and I thought it was just fine so I didn't think about it when I performed a factory reset through the IU. I shouldn't have done that...
The problems came back, first the twrp-bootloop so I tried to flash the kdz again. That failed and after that I no longer can access download mode. What happens when I try to is that the LG logo shows as it should, but then instead of going into download mode it takes a little longer, and then the phone opens up like 20 drive letters on my computer. One of them contains files in a folder called "image".
Am I 100% ****ed? I would really appreciate it if someone could help me out with this one!

S5000-F recovery request (desperate's cry)

Dear XDA members.
Things started going wrong along with failed rooting procedure. This made the device to hang on manufacturer's logo (recovery availiable).
Then I've tried to follow "how-to-flashing-lenovo-s5000-via-spft" @ zonexfirmware.blogspot.com; describing the use of SPFT to flash rom from PC. Unfortunately "PMT changed for the ROM" error made me to "format whole flash except Bootloader". This allowed to flash rom in "Download Mode" via SPFT.
Now the rom still does not boot, and additionally when trying to enter recovery mode I see only "factory mode".
So, standing on the edge I'm hesitating. Probably Firmware upgrade mode or Format All + Download would solve the problem. But things may go also the other way (much like considering my latest results).
At this point I'm even not sure whether the rom linked in the guide suits my device.
Please kindly advise.
Format All + Download almost bricked the tablet.
Has anyone an idea what is wrong with this procedure? The device is not booting and have the factory mode instead recovery mode stikk,

How to install custom ROM in Zenfone 5 if phone never boots into recovery mode

I want to install custom ROM on my Zenfone 5.
Things you should know:
.. Phone OS completely corrupts unable to boot the device (even android logo also not appear)
.. It is not showing charging symbol also when connected to charger/usb
.. Phone never boots into recovery mode (it is just restarting(vibration)! and stay idle)
.. It has TeamWin recovery project that appear after 30 mins of charging (useful!!)
So, can anybody tells me how install custom ROM (http://forum.xda-developers.com/zenfone-5/orig-development/beta-cyanogenmod-12-1-tank0412-t3285392) please don't say boot into recovery mode and do some adb/fastboot commands it is not working (volume up+power or any combination). It is just showing one big red charging bar symbol without charging.. and some times TeamWin which may helpful because it has filemanager and I can browse but I don't know how to install with that.
If you have any ideas please share me..
Thanks
You can put rom on the external sdcard and install it after TWRP booting.
But i think that something wrong with bootloader on your phone so you should try to make unbrick.

Thanks for the answer..
Hard bricked device - Just like it's name, your device is dead. It behaves like a real brick. You can have no operation on pressing the power button.
So we can make a conclusion: soft bricked device can’t be defined as "BRICKED"; the hard bricked device is the real "DEAD & BRICKED", and it can't be unbricked. Sorry for the answer to how to unbrcik hard bricked Android phone.
This is the situation of my phone and whenever I flash a zip file from TWRP I'm getting following error..
"E: Error executing updater binary in zip '/sdcard/.....zip'"
I'm googling this error but unable to get anything(trying some of the one plus one solutions to the similar problem).. Please help me..

It looks like you use TWRP by Knone which is broken a bit. So you should install TWRP by quanganh2627.
Try to flash this package via TWRP:
https://drive.google.com/file/d/0B-Fin8UxrD6PNm1NSDNQQ3JqUkU/view?usp=sharing
It will install a stable TWRP.

Yes, I'm trying that but the problem here is I'm unable to flash TWRP now (Run the command prompt - wait for device - phone starts several times but only big red battery symbol without charging/usb cable showing red bar below - boot into installed OS) that's it without flashing the TWRP phone reboots and command prompt still waiting for device even device already booted.
Interestingly now the battery showing 100% directly (I don't know ! whether it is actual figure or something goes wronng!) but still my IMEI is empty and I want to install stock ROM on this device for this purpose.
Note: still power + volume up/down to goto recovery mode not working
Any help appreciated. Thanks!!

You bricked your device.
You should use unbrick method:
