Guys, I'm completely lost.
I rooted my phone, and tryed to use TWRP recovery.
Installed Android Studio Setup Wizzard, openned command window and typed ''adb shell'', ''su''...
But when I tried entering recovery mode to go into TWRP, my phone just got Stuck.
It says: ''Fastboot mode started''
''reset''
''portchange''
''reset''
''portchange''
then i decided to remove the usb cable from the phone and it said more things, now it says ''Fastboot: processing commands''
Even tried to remove the battery but nothing works.
I am a noob when it comes to Roms and flashing this and that, and I know i made a mistake by doing this. Could you guys send me a solution for this? Just want my phone back.
I'm using the LG G3 D855.
If it doesnt start normally into Android OS your phones a goner
Take it into your local service center and tell them the problem occurred while you were trying to apply the Lollipop OTA

Hello guys,
I had my Nexus 7 2013 (Wi-fi) for almost an year running stock rom and I decided to install CM12+ElementalX. It was all good untill yesterday when I returned it back to stock 5.0.2. When i started the tablet a message popped about 5.1 update and I started the update, but in the middle of the process it said "ERROR". I rebooted the device and now its stuck on the screen where you have to choose your language, with two errors constantly popping up - "PHONE HAS STOPPED WORKING" and "NFC Service has stopped working". I press OK like mad trying to skip some of the steps,but the "touch and go" (i think thats the name) is as far as i can go.
Is there any way I can flash the stock 5.1 without USB Debug Mode. There is no way i can get in the tablet's menu. I also saw some of the othere topics with this kind of problems, but i didn't find the answer.
You don't need USB Debugging to flash the factory images... use fastboot.

I have installed ADB i Android SDK. Everythink is working fine on my Nexus 5 , but i cant do anything with my Nexus 7 which is now constantly rebooting after i managed to go through all the starting steps , when it started to install my 36 apps it rebooted by itself and now it keeps doing it.
i am having similar issue. i have tried the root tool several times with no success. ive been rooting devices since the samsung moment and i cannot get this tablet going at all. with the root tool i am able to flash twrp recovery, but for some reason it will not mount to put a rom on the internal memory. i have even tried pushing a stock rooted rom through adb fastboot and it just hangs. what else can i possibly do? could it be hardware related? this all happened after i was prompted for the latest 5.1.1 update. any tips or suggestions would be greatly appreciated. tia
Hi guys, here is my problem:
I have the 815P version of lg g4. i upgraded to marshmallow last year via kdz=> lgup=>upgrade and i made the mistake to ENCRYPTthe phone.
today i wanted to go back to lollipop because i prefer root over the newest android. got the right kdz, got the right drivers and did the deed. The thing is, i forgot to unecrypt prior to downgrading
and now im stuck in a bootloop. I can go as far as asking to input the encryption password but then the phone just sits there. I have waited for 15 minutes and it just shows me lg logo, so im guessing its a bootloop alright.
Tried the usual stuff: unplug the battery, plug it again, press up and connect the usb cable...doesnt do anything, lg up doesnt recognize it. What options do i have? im about to cry now :crying:
All I could find is to boot into fastboot use the following command:
fastboot erase userdata
And perform a factory reset again

Thanks for the response. It was a defective usb cable that was preventing me from going download mode. i used the original cable and was able to upgrade to MM, remove encryption and downgrade to LP again.
Hey, so im having problems here. I just got my new lg k10 (running on 5.1 Lollipop) and i rooted it with kingroot. after that, i decided to go play around with the ROM Toolbox app and when i rebooted it, or attempted to, i got a message with the lg logo saying "boot verification failed MISMATCH_SIG_LEN" with the error codes [410][420][430]. I already tried to enter recovery mode but it gives me the same message just with a different error code [4032] and some other ones. when i put it to charge it doesn't stay on the charging screen, it just keeps trying to boot again (which i think its called a bootloop, correct me if im wrong) so theres no way my pc can auto detect the phone. i even tried taking out the battery and still nothing. please help ASAP!!! :crying::crying:
Same here kingroot thats it. Rebooted and same thing happened. Boot verification failed. Just bought 2 days ago so I told them it shut off in the middle of an OTA update and they replaced it immediately. No download mode, recovery, nothing just LG logo bootloop with error as described above. Afraid to root new k10 until this is resolved.
Guys, did you try my guide? Check it out on LG K10 Guides, News, & Discussion
Does the op have this issue fixed i would be willing to offer my time
Sent from my LG-H900 using Xposed Modules
i found a fix
boot into fast boot by holding vol down when plugig into computer..... than use "fastboot oem unlock" command boot normally (don't mind the "cant check boot" message)
Same issue with LG V10
I am stuck in a bootloop "mismatch_sig_len" and I have tried putting it into download mode, factory reset and a couple of recovery tools that can't find my device. I have read something about having to "short" two pins with tweezers or copper, to get out of this. Are there any successful methods anyone knows of? Thanks in advance.

How did this fix your issue, my device isn't even recognized by fastboot at all.
Im in a big trouble. i was using fulmics 6.1 on my LG F400L. it was running well. But i tried to install Android N-ify to my phone and after booting up my phone says " SystemUI has been stopped" and I can't access it anymore. its not a big deal since i can't even boot into recovery. I don't know why hardware keys doesn't work for me. So only one option is left for me is flashing my phone back to stock.
Here is the main problem. Via KDZ method my phone stucks at 2% S/W. maybe its for Fulmics 6.1
Again if I try to downgrade via LGUP my phone is showed as unrecognized.
Now , how can flash my phone ?
what method should I try ?
Please help me.
Hmm are you certain you can't boot into recovery? Holding the power button to switch off your phone and then booting directly into recovery? Or removing the battery and booting directly into recovery?
Nothing happening on OS level should keep you from booting in the recovery..
As for "Device not recognised" -- I had that myself, and usually it's due to the COM ports in Device Manager in Windows. There are a couple of guides for restoring to stock around the forum, you'll find most helpful.
Hey guys,
I would have liked to get the OREO update, because it said every time is up-to-date, and I wasn't patient. because all of these already get it, and the battery life was terrible with, and I have just 30 days to cancel the phone if I'm unsatisfied with it, so it was urgent for me to update and try it.
But I didn't know enough from the newest devices, so that I need unlocked bootloader to flash STOCK ROM or ROOT or for flash RECOVERY
Mine is XT1789-06, I tried to flash first this ROM:
https://androidfilehost.com/?fid=962187416754456314
It didn't tell this is TMO. :/
This changed my baseband to TMO and my boot image to T-mobile, after I didn't have signal and the fingerprint sensor didn't work.
I wanted fix it with RETAIL ROM flashing.
I tried to flash this: https://androidfilehost.com/?w=files&flid=241773
After that my phone didn't boot, says your device is corrupt.
Cause this I tried to flash back the previous version so this: NASH_RETAIL_7.1.1_NPXS26.122-68-4_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
from here https://firmware.center/firmware/Motorola/Moto Z2 Force/Stock/
But no result. The baseband stucked on TMO, the phone is not start up. Fall back to fast boot mode.
After and mean while these things I tried many things.
The Motorola Device Manager isn't working at all.
The Software Upgrade Assistant what the phone want when show boot up failed message isn't working just say processing device information and isn't going further. I don't understand why the phone ask it, because that is for verizon phones.
The RSD lite says the model name is Fastboot nash S and isn't start to flash anything, when I press the start it says the phone failed to switch to fastboot mode, but it's in that.
I tried already flash more different ROMs, but didn't work one of them .
Recovery is unable, the phone isn't rooted, the bootloader is locked, however sometimes it showed ""Your device software cannot be checked for corruption. Please lock the bootloader", but I checked in the powershell and in fastboot mode I looked what phone says, so it's locked.
I was thinking maybe if I unlock it will solve the problem, but I can't turn it on, so the developer options are unavailable and I don't know maybe it won't help, if I can do it somehow.
Now if I want turn on the phone it's going to fastboot mode right away or say your device is corrupt... and after.
I can't try flash it through Qualcomm 9008 because the PC recognise the device for fastboot device.
In the device manager the computer shows Motorola ADB interface.
I try to unbrick for 3 days, please help me.
Thanks a lot in advance.
Same here, if you find anything out DM me
I already contacted with the phone, I will bring back to Repait it.
I couldn't find out nothing, I tried everything what was possible.
i think i found a solution i just dont know how it works exactly, something to do with a batch file and a full flash of the phone
