Hi Guys,
I have Vanir ROM installed and had a problem with SIM. It was showing a SIM card symbol instead of network bars. I wasn't able to connect to mobile network.
I decided to wipe davlik and other cache, reboot it and give it a try if it work.
After wiping memory and rebooting it I saw "No OS installed are u sure to reboot"
-- I knew at this point I was screwed. I shouldn't have rebooted it :'(
After reboot it got stuck on Google logo (Black screen, white Google logo)
Now If I try to get into bootloader/Fastboot mode it doesnt as my volume button wasnt working from some time
---- I know I should have got it repaired :'( ---
Please tell me is there any way I can go to fastboot mode
Pls guys somebody reply..

Do you have adb set up on your computer? If so, you could probably use "adb reboot recovery" to get into recovery. Then you can download a ROM to your computer and use adb to install it with "adb sideload romfilename.zip".
Remove battery and put again and press volUp+volDown+Power to enter fastboot mode, then enter recovery and wipe all. Flash factory image and custom recovery, copy ROM on sdcard and then flash. It will connect to mobile network 100%
Is it just volume down that doesn't work? You could volume up+power for boot to recovery.
Hi,
This morning my rooted + xposed Selfie rebooted without any reason and now it is stuck in ASUS logo bootloop!
I can enter fastboot mode ("Fastboot Mode!!!" is written on the top of the screen) but I cannot enter recovery mode.
I tried to reflash boot, recovery and system images but nothing changes.
What's happened and what can I do?
Thanks!
D855 - How to restore Download mode? - "secure boot error" only when starting DL-Mode
Hi there,
i wanted to install my phone (D855 32GB) from scratch, because of some problems (factory reset not possible, phone is not reset completely). Some time ago, i unlocked fastboot-mode with LAF-Toolkit. To flash a new KDZ using "LG Flash-Tool" i needed the download-mode, so i tried to restore laf.img via fastboot.exe flash. But i think i did something wrong (wrong file/version?) If i actually try to enter download-mode via volume-up button while connecting the usb-cable, i get a "secure boot error".
I can normally start and use my phone (Fulmics 4.2), i can boot into TWRP 3.0, but i dont know how to repair the download- or fastboot-mode.
- I cannot use fastboot.exe to repair laf.img, because fastboot-mode is needed
- I cannot use LG Flash Tool, because download-mode is needed
- I cannot use LGUP, because download-mode is needed
I think, i miss something. Can someone please help me me? Is there a way to repair this using TWRP? Is there a way to get back to stock completely?
At least, i was able to restore fastboot-mode using "LG Laf Recovery Multitool v1.2" .
But now? Stupid question: How do i do a KDZ-Flash without "download mode"?
Hi guys,
I have a nexus 7 2013 which boot loop (or any watchdog restart ?).
If I try to normal start this one, I will get the Google logo for few seconds, then it will restart on its own.
If i press the volume down during this process, I can boot to bootloader, but same way, after few second, device will restart.
Any clue on what can be wrong ?
Thanks

Hello, connect external power and try again. If it works now, you will have to replace the battery.
If it does not work with external power and it can not stop in bootloader/fastboot mode, then the hardware is faulty or the bootloader is corrupt.
External power does not change anything. Still boot loop, so really should be a hardware issue.
If I keep volume up key pressed, it boots, but almost unusable if I have to continuously press the volume up key.
Same when in bootloader: if I continuously press the volume up key, it does not reboot.
I've tried to erase everything with fastboot, but cannot do most of the operation. When trying to format data, it says that partition does not exists (it exists, as it can boot !)
Bootloader is locked, so cannot go with TWRP for example, as I cannot validate the on screen confirmation needed to oem unlock.
Do you know any way to unlock bootloader without use of onscreen confirmation ?
I don't know if that would help, but when I was installing Lineage OS and updated TWRP, I also boot looped once on recovery (recovery itself was boot-looping), and re-downloading (from another browser) and re-installing recovery at fastboot mode fixed my issue.
I cannot unlock the bootloader because of this issue, so cannot flash anything
Could be broken power button, if it is stuck and pressing it continuously.
Are you able to reach your recovery to factory reset?
I mean can you reach it from the bootloader menu?
If not you could try to put twrp.img or recovery.img into your PC adb&fastboot folder and try
fastboot boot twrp.img
or
fastboot boot recovery.img
Don't know if this works with locked bl
Edit: may type
fastboot getvar all
and post your result, hide your imei if you got one
