LG G2-D802 , power on - lg logo - black screen, doesn't boot up.

Hello,
I tried installing custom rom on my G2 , here is what I did (more or less)
- rooted the phone - I think with ioroot
- flashed twrp (I think with flashify)
- couldn't boot into recovery, got "Certificate error"
- used autorec
- now twrp recovery worked.
- wiped data / cache / system
- installed Crdroid / lineageos + gapps
- rebooted
And from that point I'm stuck, I get the LG screen for a sec and then a black screen.
To boot up again I flashed the stock rom, but I want custom!!!
what can I do ?
BTW, in some of the guides I saw it said that I need to unlock the bootloader ? but when I try the guide and use the first command to boot into bootloader, all it seems to do is just reboot the system regularly.
did this "adb reboot bootloader" and that is it, "fastboot oem unlock" just said "Waiting for device"
thank you.

connect it to computer. does it shows qhsusb_bulk in device manager? if qhsusb_bulk mode then use unbrick tutorial or use srktool to unbrick...

Nah.
U just didnt flashned boostack.
Go to twrp (power + vol up)
It will ask u abount factory reset. Press Yes 3 times ( dont worry nothing will be erased).
In twrp do again wipe ( system, data, cache,davlik)
Install caf bootstack. In download select ur variant. (https://forum.xda-developers.com/lg-g2/development/boot-g2-hybrid-bootstacks-t3183219)
Than install rom + gapps.
It should work.

i got the same problem months ago.
it worked fine.:good:

I have the same issue, except I can't get into TWRP. I flashed a bumped stock bootstack and am stuck with the LG logo to black screen. Factory reset screen asks to press power to confirm, just goes back to black screen afterwards. TWRP won't load up no matter the combination. I can get to download mode, if that helps any.

did you manage to fix this? I'm alsostuck at this, flashing stock rom show skipping partition to me.

I ended up using the download mode to flash a Kitkat kdz with the LG Flashtool 2014, then rooted, flashed TWRP with autorec, then ran mr. bump, installed TWRP 3.1.0, and restored my nandroid backup.

System not booting, unable to open recovery and fastboot. Help!!!

Today I decided to root my OP2. I did all the regular procedure for rooting. Fastboot > OEM unlock > Flash TWRP 3.1 > flash SU.zip via TWRP. Now this is where the problem started, after flashing SU.zip I rebooted but it was not rebooting, the 2 white dots kept rotating for quite a long time. so I turned off the phone and flashed the SU.zip again and rebooted but still didn't worked, so I went back to TWRP booted into fast boot and flash a lower version of TWRP, Now TWRP won't even start the screen got stuck on one plus logo. so I powered off again and tried doing a normal start up but that didn't workout, so I tried to start fast boot manually (power button + volume up) but this time the screen didn't even turn on . Is there anything I could do to fix it.

use method 2 or method 3 if you have efs backup by terminal or efs backup by spanna software zip. (P.s. dont rely on efs backup by twrp)
and if don't have efs backup then after method 2 or 3 flash oos 3.5.7 to get ur imei numbers.

What did you restore? System and data?
Also for Pixel experience you need a 64bit recovery cause it's a hardware 64bit rom. You can use this one https://forum.xda-developers.com/mo...recovery-twrp-3-2-1-unofficial-touch-t3722206 just flash it through your existing twrp.

System,data,system.img,boot and I have 3.2.1.0 twrp it is 64 bit or not?and I restore about 6 gb,so why after moto logo ,the black screen appear?i don't have laptop ,so can do anymore ,my battery is draining.

Where did you download the twrp? If it's not from the link I wrote than surely not.
Can you reboot to recovery, wipe cache/art partition and reboot to system? Why you can't charge your device?

First thing ,can 3.2.1.0 is 32 bit or not?
Second,if above is not 64 bit,i downloaded from your link and put it in sd card through otg cable(because my phone is not turn on ,and I can't installe from same phone ).
Then I go to install>tap on flash IMG>twrp(64 bit)>recovery.
But red line showing on output and show - error for flash IMG ,there is no directory.

3.2.1 can be 32bit. I really don't know what you've downloaded...
Your flashing method is correct: install>tap on flash IMG>twrp(64 bit)>recovery
Can you post a screenshot of the error please?

If it possible than I will surely do it.but now I don't want 64 bit twrp (when my mobile turn on I flash it through your link)
But my question is if pixelexperiance show error 255 error and if I want revert back to original stock rom through twrp backup and tap restore>backup>done then why my mobile is not start after Motorola logo and stop to black gray screen????so,this is soft brick or hard brick? Personally I don't know what is soft brick or hard brick but in both case mobile is not turn on.

HUAWEI PRA-LX1 dead? Stuck at bootloop after flashing Custom ROM [HELP!]

Hi guys.
I have a Huawei P8 Lite 2017 PRA-LX1 Single Sim, no brand EUROPE [PRA-LX1 8.0.0.400(C432)].
Yesterday, I suddenly had an idea: unlock OEM (I have a code from before Huawei stopped giving them),
flash TWRP, Magisk, then root and finally flash an official DotOS 3.0 Build for EMUI 8 devices
(all packages built for prague devices like my one). So I searched through XDA and other forums to find TWRP and
other necessary files (all listed here):
• TWRP Recovery: Google Drive "TWRP 3.2.1-0 April 8th build Round 2.img"
• Magisk - that's useless to list - both APK to install and .zip to flash via TWRP: Apkmirror
• Custom ROM: xda-DarkJoker360 "Dot OS P v3.0 for Huawei P8 Lite 2017"
• GApps: OpenGapps ARM64, 9.0, nano
So i unlocked the bootloader using the adb commands everyone knows.
I flashed TWRP using this guide: https://www.youtube.com/watch?v=ijAuoxlnzlo (I'm italian).
From the phone I downloaded Magisk Manager, installed, then from there I downloaded the flashable .zip.
I flashed the Magisk .zip from TWRP.
I checked the root status with Root Checker App: phone was rooted.
I moved the flashable DotOS ROM .zip and the GApps .zip to a 15GB non-formatted SDHC.
Inserted the SD in the phone.
From Magisk Manager i rebooted the device in TWRP Recovery mode.
Followed the "CLEAN FLASH" instructions from the DotOS thread:
Code:
• Download the latest build and GApps
• Reboot to recovery
• Make nandroid backup (Not Necessary)
• Wipe System, Data, Cache, Dalvik
• Flash the latest build and GApps
• Reboot
- I tried to do a Nandroid Backup, but since TWRP didn't want to do it (I was getting errors), I continued without backup. (FIRST MISTAKE)
- I did the Wipes, but there was problems with the Cache wipe: "Failed to wipe cache" or something like that.
So I looked for a solution in XDA, and i found something like "Do a data format since the datas are Encrypted"
- I did the Data Format
SECOND MISTAKE, because the Format deleted the stock OS, and I had not yet flashed the custom one (DotOS).
- It rebooted in TWRP and i flashed DotOS and GApps. I did another Cache and Dalvik wipe (THIRD MISTAKE)
and i rebooted.
- I saw the beautiful DotOS bootanimation playing on the screen, but then..
- the screen got black, and the Huawei logo appeared. I had an heart attack.
- The black screen with "Your phone is unlocked and can't be trusted" and the three options appeared.
I turned off the phone.
Now this is my current situation:
I turn on the phone
- The black screen with "Your phone is unlocked and can't be trusted" and the three options appears.
- If I let boot, the bootloop goes in action (DotOS bootanimation -> Black Screen -> Huawei Logo -> "Your phone is unlocked" screen again)
- If I press Vol+ for more than 3 seconds, the phone boots into Huawei erecovery. Now from there i can:
- "download the latest firmware and recovery" but it fails at 5%
- Do a factory reset. I have to type "yes" to confirm. Then it shows a "Your phone is unlocked" screen but without options for a while, and
then, without doing nothing, it boots into TWRP
- Reboot (bootloop goes in action)
- Shutdown
So, what do i have to do? That's my only phone (don't ask me "so why did you decided to do this", i know already).
If you have any solution, and maybe you had a similar experience, please (PLEASE :crying tell.
Thanks in advance.

[SOLVED] Unable to enter TWRP/Stock recovery and can't boot into system

Hi,
I have been using my P Smart (FIG-LX1) for a while with LineageOS 16 and decided to move on to Android 10. Installed LineageOS 17.1 (found it on this forum) and pph-Magisk 20.3 for root - it did work, but the system was unstable so i decided to try AOSP 10.0 instead. I entered TWRP, wiped cache,dalvik,system and data, flashed the ROM, gapps etc. It was advised to now flash stock recovery and use it to do a factory reset - and now i'm stuck here.
After flashing the recovery_ramdisk img the phone stopped being able to enter any recovery at all. The system itself does not boot (stuck on the "Your device has been unlocked (...) Your device is booting now..." screen forever), the recovery never appears (previously in the start screen with 'unlocked device' warning it used to suggest pressing volume UP to enter recovery, now it only shows "Your device is booting now"). As i can still access fastboot, I tried flashing TWRP again - the TWRP splash screen does appear, but the phone gets stuck on it. Also tried flashing another system's img - nothing changed.
Is there anything I can do or did i just brick it completely?
Thanks for help!
SOLVED:
Apparently running fastboot erase on system and userdata partitions made me able to boot into recovery/erecovery again. I do have another problem now, but it's not connected with this one so I will create another thread for that.

Could you try help me? I can't even get ADB to work anymore
