I've successfully rooted my T-Mobile LG Leon, and I've successfully installed TWRP, but for the life of me, I can't get the phone to boot into recovery. I can RE-boot into recovery from TWRP manager, but I can't actually boot into it from a fully powered-down state. I've tried every combination of the power and volume buttons I can think of, and nothing ever works. Download Mode works, the factory restore menu works, but I CANNOT get into recovery. Is there a very specific set of instructions anywhere that I can follow?
EDIT: Okay, I finally figured it out: You need to actually select to do a factory reset, and it throws you into the recovery menu.
Yeah, it was because the stock recovery doesn't exist as a menu, when you're running stock and enter the adb command "adb reboot recovery" it will reboot to the "factory reset mode" and the actual file of this mode is stored on partition named "recovery". Choosing the factory reset option boots the custom recovery because it replaces the said " factory reset mode" and that's the trick.
You can access recovery from the powered off state by holding volume down and power on until you see the lg sign. Without letting go of volume down, depress on the power button before clicking it back in and holding both buttons in until you see twrp pop up.
If you reboot to recovery now, it''ll probally say secure booting error. Simply go to the Developer options and enable OEM Unlock and that'll make you boot to it
You boot in the download mode by holding the vol up 10 seconds and during this 10 seconds you insert the usb. The LG Leon brand screen will come on a minute then it will go into download mode. It says not to unplug until firmware is done updating. So I guess you should have your custom recovery or whatever before you do this. I have only got this far, and thusly it sits. All Dressd up with no where to go...haha

can't find "enable OEM" at all in developer options. have phone hooked computer, and on, it's sending and receiving. No OEM. Isn't there.
See, I'm trying to root this without using KingUser. Since I found that it was pretty easy to do from the very beginning with Samsung, and I just don't see any way to do it here. I can't get ADB Devices command to see the phone.

I think I have the same issue, but I rooted my phone using kingroot, I haven't tested the adb commands, I just want to use twrp but no luck, it says Secure booting error and I can't find OEM Unlock option in Developer Menu.

I got a good way to get it rooted with SuperSU. Ran a command window script I found out there. It worked and now I have SuperSU root. I also figured out how to get into recovery. It looks as though my phone is not the standard LEON that people are talking about here. It's got a few designations, and the T Mobile site advertises a Leon that seems very similar and is called by the name most are using..
Anyhow my LG Leon is designated as a H320. It also carries a v10 desiganation, v10b. The v10 is variable from a-h or a-i. It would seem that once it is updated to 5.1.1 android it gets upped, and becomes unrootable. Mine being a v10b was rootable, but it took me a while to get used to it, and make the command window work.
Unfortunately for me one of many things I tried before getting it rooted, was ADB fastboot. And since this told me to wait for too long, I pulled the plug on it and pulled the battery to get back into "normal" operations. Perhaps I should have waited, because after finding out a few things about the phone, I discovered the true way to get it into recovery:
The real way into recovery for my phone, is to (from power off state) hold the volume up, a few seconds, then plug the USB cable which is going to the computer into the phone. While holding the volume up until it comes to recovery. This will activate the recovery, (Now for me it activates that fastboot command line...and does nothing else). This was the bit of information I could have used from the beginning, that no one knows. All these places tell you to hold the power and volume up, and then let off power when the screen changes, but that never worked even once. You just hold the volume, and plug the USB from computer. This works.
For me it goes into a "FASTBOOT" header at the bottom of the screen that never changes.
I believe it does this because of my unsuccessful attempt to fastboot it before. And it does not have the right driver to get recognized in the computer. So I'm screwed as far as the recovery goes now.
It is rooted though. And it doesn't seem to have any alternate ROMS available anyways. so we're dealing with the loss of the recovery.
When I do try to use an app such as TWRP manager or CWM (ROM) Manager to reboot into recovery, I get a "boot certification verification -1" error instead of the fastboot line at the bottom of the startup screen and it boots normally from there. So many people asked about this "boot certification verification -1" and NO answers are available anywhere online. So that's where it stands for this phone right now.
Anyone know what driver I should use to get the thing recognized in the computer? I have downloaded a zipped fastboot tools, and it won't get recognized inside the driver manager as "android" only as "unknown device" so I can't use that route....I'm thinking about doing a factory reset to try to erase the fastboot attempt. That may not help though. Anyone?

I dunno, I have the H340AR, with this phones happens the same that with the Samsung Galaxy Ace 3, there are, 3G versions, 4G versions, regional versions, etc.. GA3 have 7275R, 7275B, 7272L, 7272T, I dunno, maybe if we could get a device tree for a H340 and an H320 we could make some TWRP and CM compiling, but I just can't figure it out how to make a device tree or even where to begin..
I successfully rooted my H340AR with Kingroot, it works like a charm. I haven't tried fastboot and I tried to install TWRP in this link https://dl.twrp.me/c50/ but I get that F error "Secure booting error". I guess I have my bootloader locked, so I'm trying to figure out how to unlock my bootloader.
I'm trying to contact with some developers and see if anyone can help me build a device tree.

Hi, I have that same phone H340AR LTE. I rooted it with Kingroot and also tried to use TWRP to gen into recovery and got that Security error. I only pulled out the baterry and turn it on again so it booted normally. I made a factory reset because I read that it could be a problem of OTA firmware update. Then I installed TWRP and BusyBox again and tried to get into recovery from TWRP option. When I did that, it showed up the Android lying in his back with a red triangle. I pulled a out the battery again and yes, it seems very dumb and simple but it worked and could reboot the phone.
However, I can't get into recovery from TWRP yet. I read that the problem with us not being able to unlock the bootloader(we don't have the OEM option) is because Leon has Lollipop 5.0.1 and OEM is for 5.1.1

when i pressed factory reset all it did was to a factory reset even though i flashed twrp.img successfully... help?
lg leon h345 lollipop 5.1.1
This device has a locked bootloader. If you flash a custom recovery on it, it will not boot into recovery, but will report a security issue. You will lose all recovery functionality, including factory reset, adb, fastboot. If your phone fails to boot, you have a brick.
Hey XDA!
Got my Nexus into some trouble today. I Was running stock rooted 5.0.2, received an OTA update for 5.1. Ran the update and it sent me to my TWRP 3.0 recovery. Restarted the device and found out the update did not work, leaving me at 5.0.2. Ran the update again like a tard, took my to the stock bootloader. TWRP is now no where to be found... In fact there is no recovery to be found. When I select the recovery option in the bootloader it goes to black screen then redirects back to the bootloader. When I select the "start" option, it's reboots the device taking me to the bootloader. I have attempted a hard restart with the power button but the device hangs on the Google logo forever. I have tried to use the Nexus Root Tool but it can't help me since the device won't connect via fastboot, or ADB.
Any help is appreciated.
Hallo,
got the same problem, how did you resolve it ??? Thanks a lot ...
Same here. I can't connect to the device by no means. How did you solve your problem?

you mention it wont connect via fastboot but you can still reboot with the pwr + vol- to get menus of some kind.. ? if the screen is backlite even just a blank screen but you can see it light up theres still hope. All i can say is try to reboot the device into fastboot an then try Nexus Root Toolkit an see if you can reset to Factory to restore the stock recovery partition along with reset the OS to which ever you select and start over .. Good Luck Flashing... the only way i can say your SOL is if when you plug it into your PC an it pops up with the error "Device Malfunctioned,....." then you SOL Good Luck Flashing :good:
EDIT: Sorry didnt notice it was resolved in the title..
Hello!
I recently got a hold of a Nexus 6P which has the bootloop error. The previous owner never rooted it or hacked it in any way.
Meaning OEM is locked
Bootloader locked
No TWRP
My question is:
Is there any way to save this phone? I searched for almost an hour and some people claimed its doable whilst others said to give up.
Regards

Super easy to fix.
Download the newest Full OTA image for angler: https://developers.google.com/android/ota
Then reboot to recovery by holding VOL-DOWN and powering on, then selecting recovery from the boot menu. Then choose "Apply Update from ADB", and use adb sideload /path/to/filenameofotaimage.zip to revive it.
Hey!
Thanks for your fast reply and your helpful tone.
However, when I choose Recovery mode it once again stucks in bootloop resulting in me never accessing recovery mode

I am not sure my first reply was sent (having an unstable connection) so trying again:
When in bootloader and pressing recovery mode it goes straight back to bootloop. Hence, I cannot access recovery mode. Feels like a catch-22.

maybe if you posted it in the correct forum, you would get an answer...
Moved to the correct board...
If you can't boot the phone and you can't boot to recovery and Android debugging and oem unlocking are not enabled, there isn't much (read anything) you can do. Maybe take it to a local repair shop and see if they can replace the motherboard for you.

Heating the phone temporarily boots the phone. (You can also check videos for saving data in bootlooped LG phones)
Hi, I bought a second hand zte axon 7 a2017. I want told it was rooted or anything. Power button is squashed in so got it for cheap so bought it. Phone runs fine on stock rom and for restarting etc I use mi pop and power button can still be used by poking it hard at an angle with stick etc. I'm familiar with rooting, flashing etc but it is the first time I'm using zte so it's bit different.
Issue is I want to root it to get rid of bloatware etc. I downloaded Root Check app and it says it is rooted and busybox is installed but there is no super user app. Funny thing is I have no means to check if bootloader is unlocked and can't even boot to bootloader mode as it just gets stuck at zte logo when I try to boot to bootloader mode from recovery mode. I get to recovery mode by restarting the phone from mi-pop and holding the volume up button. I don't even think there is custom recovery installed too which I don't know how that's possible as my understanding was custom recovery needs to be installed earlier in order to root.
Can someone please throw some light and give me some guidance. I want to go full stock but rooted and want custom recovery too just so that i can make a nandroid back up.
I'm on Mi favor 4.0
ZTE_A2017V1.0.0.B07.0
Thank you in advance
I'm on the US variant so I'm not too familiar with yours. I would suggest starting from stock, and downloading MiFlash, and the latest MiFlash edl package for your variant.

Okay, couple o' things:
- If your bootloader is unlocked, there should be a screen when your turn on the phone that says 'Your phone can't be checked for corruption. Please lock the bootloader' which is there for around 10 secs. If you use the volume buttons from there you should be able to select recovery or bootloader
-It is possible that you don't even have a working bootloader mode. IN CASE THAT YOU DON'T HAVE THE SCREEN I PREVIOUSLY TALKED ABOUT, try with adb: install adb, enable usb debugging, authenticate in the phone, "adb reboot bootloader". If it reboots into the bootloader (Should say START in green plus some text) then you can unlock the bootloader. But follow a guide before attempting that, or you'll risk a brick
-Having the stock recovery doesn't necessarily mean that the phone is not rooted. If you have the stock recovery it could be because the previous owner simply rooted it, used it, then flashed the stock recovery and sold the phone like that. Which is really weird in itself
-What you should do to recover from this mess is use MiFlash. Find a package called "A2017_NOUGAT_FULL_EDL" (might have a version number somewhere, just use the most recent). Enable OEM unlocking and USB debugging, then issue "adb reboot edl". The phone seems off but it's not. Now unpack the file and install it to the phone with MiFlash.
After you reflash the system you can proceed with a guide. If you get the warning screen when you turn on the phone then your bootloader is already unlocked and you can proceed with installing TWRP (maybe via axon7tool) then flashing Magisk.
Hi, just bought a phone for my son secondhand, it's going to be sold again if I can't fix this! The phone was sold cheap as it had software issues (of course) so I figured I could fix these and get it going (install custom recovery, ROM etc). I'm slightly stumped at the moment, so maybe you can help me.
The phone's defaulting to the bootloader screen, lots of info on this but the key thing I noticed was that it says 'the device is locked status code: 2'.
Clicking 'start' takes me a 'warning unlocked bootloader screen' then it runs through the 'hello moto' startup screen and back to bootloader
Clicking 'recovery' - there is definitely no working recovery on it, I just a get the dead robot with 'no command' underneath.
Clicking 'Factory Mode' allows me so far through the startup (after the bootloader unlocked warning), and you can get so far through setting it up, but because the battery is so low (it's permanently on with the bootloader when plugged in) it never seems to charge up enough, and either way the screen freezes at or around the final setup steps and then it reverts back to bootloader. I thought if I got into developer options and security, I could enable the USB debugging, OEM unlock etc, but no go there.
I've installed Motorola USB drivers but it doesn't seem to be registering on the PC (Windows 10).
There is some suggestion on other forums (less reputable!) that the locked status code may mean the bootloader has been relocked, but this seems contrary to what the phone is telling me.
Any ideas welcome, thanks - it's a lovely phone, just not much use at the moment.

OK, some progress, I have now unlocked the bootloader, so have the UNLOCKED Status Code:3 which is good, unfortunately has not yet helped with my issues. I can't use ADB, but MFastboot tool is working, so can run commands from that (hence me getting to that stage). Tried reinstalling firmware, may try and do this again now bootloader unlocked....

I have now managed to flash stock firmwares using Mfastboot tool, but hasn't unfortunately fixed the boot up issues. However, I have now worked out how to access the recovery, by reading other posts on different Motorola phones:
boot to bootloader, power+vol down
in bootloader select recovery using the volume up/down buttons, press power button to select
phone boots into 'recovery,' showing the dead android with no command
at this point hold down the power and volume up, then release volume up but keep power held down
phones boots, by magic, into android recovery, where you can factory reset, wipe cache adb sideload and install from SD card
I now need to try and get a flashable recovery to sideload, as the attempts to flash it don't work for me. The OS I seem to be on is reteu 7.1.1, so I will try and go for a lower version, and see if that allows me to flash the custom recovery I desperately need.
But....things are improving slowly....:laugh:
