Hi, I'm having trouble booting my LG Optimus G into recovery mode. I've rooted the phone and installed ClockworkMod recovery. When I try to boot into recovery, either from the ROMmanager app or by holding Volume Up and Power, it comes up with the LG logo and gives this error: Secure Booting Error! Cause: boot certification verify. It just stays like that until I press and hold the power button again until the phone shuts off entirely. Then I'm able to boot into the stock operating system and the phone works fine, but I can never get it to boot into recovery.
The error I mentioned above seems to be a well documented error on the internet, but it seems like other people that are having the trouble are completely bricking their phones. Mine is able to come out of it. All the solutions I'm finding pertain to a phone that's completely bricked and involve taking the phone back to stock. My phone works fine with the stock ROM, but I'd like to play with some custom ROM's.
Any ideas? Thanks!
I am having this same issue, anybody resolve?
Sounds like you don't have the right recovery. If you're already rooted, I believe FreeGee is the go to app for setting up recovery and all that.

Rom Manager sucks for most phones and has for years.

I recently got a secondhand Verizon Motorola Droid Razr XT912, intending to unlock it and use it with my t-mobile account. Coming from iPhone, I've never used android before so i took a few weeks to grow accustomed to the stock OS before rooting it. I learned it, and eventually, although it took several days, I also rooted it.
But today, when I attempt to boot the device, i see this glowing X logo, which my friend thinks might be the nexus logo (bootloader?), forever.
Never goes anywhere, just stays on X. I can only reboot it by holding power+volume down which makes it again boot to the X. I'm not sure if this is considered a boot loop - seeing as it doesn't actually loop, just hangs endlessly. It seems my only way of shutting the device off (power button does nothing) is to enter the boot selection menu (Vol up+down at startup) and choose the "AP fastboot" option and in that mode i can power down with a tap of the power button. all the other options bring me to the X, except recovery, an ill-android-logo-with-exclamation-point.
How did I get to this point? I tried to flash a ROM to replace the stock Motorola Android - trying first AOKP: First I backed up using myBackup, then I chose the link for "spyder" at the download list and followed a guide telling me to download this app and I did, but a different guide told me I would need CWM so i got that too. I didn't know how to add anything from within the app so i reboot to get too the boot menu, and chose the AOKP zip file - which worked for a bit but proceeded no further after "Booting...". I tried several times and messed around with the menu but I thought maybe I needed CWM so I chose that zip and it didn't work either.
Has anyone been in a similar situation? It sure seem like I bricked it. I discovered Recovery Mode has a hidden menu when you press the volume buttons, but choosing "install update from external storage (SD card)" then it fails as in valid for every zip I have tried. I thought maybe it needed to be signed or official so i downloaded what i found to be the stock update Blur_Version.6.16.211.XT912.Verizon.en.US.zip and that was accepted but eventually failed as well. The factory reset option there does nothing. I tried using the Fastboot method as well but it never finishes without stopping, on 6/18 or 2/18 or anything for a different reason each time.
What haven't I tried?
So I flashed a new ROM by the Spanish guys at Team Force (great looking ROM), via CWM, and so naturally I got the boot loop problem.
Normally solvable by turning off the phone, booting into recovery and then performing a factory reset, right?
Here's the problem - this appears to be one of the only android cellphones in existence where you CAN'T boot into recovery using the normal power + volume key combinations.
Essentially, I've bricked the phone without actually REALLY bricking it.
Did I miss anything, or does it sound like a quick end of line for this phone?
Edit: Well, if I connect my phone via USB and have ADB running in the background, holding the volume up key during the boot loop does bring up recovery mode.
It seems to me that the installation of said ROM simply doesn't fully complete before it tries to reboot itself, which could be why this is happening.
I apologize if this is in the wrong place, and I've really tried searching around, but nothing seems to work/ is tailored to the m8.
So, I just got an M8 new out of the box, rooted it and successfully installed cyanogenmod. Problem is, I was playing around with it, trying to get the GApp store and somehow (did what i think was) deleted my roms completely. Now upon booting up the phone I just get the "This build is for dev..." screen, and with the volume down+Power button to access recovery mode I constantly get put back to the fastboot screen. I tried flashing a custom recovery as in "Phone arena CWM flash recovery" guide, but no luck because my computer is reading the device as offline. I honestly have no idea what to do, and if anyone could help me I would be so greatful...
TL;DR: Stuck on boot screen, can't enter recovery mode, think i deleted all my roms, help please
On a scale of 1 - bricked, how bricked is my phone?
HUGE DEVELOPMENTS, GUYS! I've been able to access recovery mode again by re-flashing ClockWorkMod.

Click to expand...
Click to collapse
On that scale, you are zero. If the screen comes on, you aren't bricked.
hello everyone
this phone is NOWHERE... i cant believe how few people have this phone in the hacking community.
I've used a guide seen here
https://www.youtube.com/watch?v=BCiq21WsFEc
essentially I rooted it in KK successfully. Then I installed TWRP through the twrp app... installed successfully. no error.
Went to reboot, phone does not get past splash. Recovery instantly goes to black (powered off) screen with red LED (tells me the phone is kind of on.. but some serious hardware misunderstanding taking place.)
How can I restore the stock recovery? While it is in this no-display-red-light mode it appears on my computer in DFU... so I know it is possible to still get in there, but I cannot find anything about the stock recovery for this phone.
Can't believe ZTE has little to no support for this phone...
Possible solution
That video seemed to be for the newer model of the zte grand x, thats why its called grand x plus. I had tried it on my phone and it was like stuck in a power up loop, what i did to get out of it is to go into recovery mode by pressing and hold the power button plus the up volume button. One i got in there i just rebooted it. Try that out and see if it works. Im still looking around for a solid root for this phone
I've seen lots of comments about not being able to boot into TWRP to flash something after rooting and phone is all setup. Quickboot and Tasker can do this but I wanted to do it with on/off/volume buttons (like my old Samsung, (I'm spoiled)).
I locked up my phone fooling around with the build.prop. I could not get beyond the LG logo. I decided I had to start over with factory restore. (Hold Volume down/on/off at same time, when logo appears release on/off for 1 second, still holding volume down, and press on/off and hold until it boots into Factory Restore mode.)
I went through the prompts to factory restore and on the last "Yes" the phone booted into TWRP instead of into a Factory Restore. After restoring from my nandroid backup I tried it again and it worked again. So, I've concluded if you have TWRP installed this is the method I used to boot into it from power off.
Tested and confirmed on my v10 as well.
That's how I used to do it on my G3 when I couldn't boot properly.

Woohoo! Thanks. Worked.
OMFG! it wasn't until I was about to make a post about this to ask for help that this post came up and I am ever so grateful! Like others who have had trouble getting there with the hardware buttons, I tried so many ways and searched far and near with no workable solution until this!
How'd you install recovery ? I'm having h960a model and i can't seem to be able to root or install recovery.. i've tried every method out there .
As far as I know, only T-Mobile USA version has root and custom recovery so far.
