[Q] LG G2 stuck for no apparent reason

Ok, so I installed the LG G Pro 2 ROM, had it rooted and ofc had stock recovery ... My Wi-Fi (for some odd reason) didn't want to turn itself on, so i tried to restart the phone .... It got stuck in a bootloop, so I'm having following problems ... I entered stock recovery and tried to wipe the rom, no help, still stuck in recovery .... Can't access download mode to flash a KDZ file, since I cant really "shut" the phone down, rather just "restart" it by long pressing the power key, and if i try to hold the vol up button while connecting it to the computer to enter download mode, it fails every time and it just goes to the LG logo and get's stuck there .... Can I somehow shut the phone down completly or flash a kdz file from stock recovery ?
Edit: OK, I somehow did shut it down completly ... I think i held all 3 buttons at the same time for like, 10 - 15 secs and it did shut down completly ...
So - sorry for the thread, mods can lock it!

E612 stock bootloop. Cannot perform hard reset

Hello,
I have a LG E612 (Stock I have not installed any ROMS etc) After dropping the phone it no longer boots. When powering on the device it shows the LG logo then powers down and repeats. I have tried a hard reset (http://www.hard-reset.com/lg-optimus-l5-hard-reset.html) which unfortunately does nothing. If I connect the device via USb the the PC and try the hard reset I can get it to show the "download screen" Could this guide fix my issue? http://forum.xda-developers.com/showpost.php?p=52241564&postcount=19

Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

The bootloop is just showing the ''ZUK logo'' in the middle of screen and "'powered by Android logo'' below,and the phone vibrates everytime it flashes these logos. I tried QFIL but it can only detects the unit on the first boot or first flash that is 2 secs. only from the time i press the power button, and then it disconnects and not detect the unit again. Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx

Can y get to fastboot ?

im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.

Same problem

The link is not accessible now. Can you let me know what you have done. My phone is in a boot loop now and showing only Logo and 'powered by Android' message. It keeps turning on and off again and again.

Guys when u are in fast boot mode .. pls install Twrp ... After insatlling that press power button abd vibration comes hold volum doen+volume up button at the same time ..
Then u will be getting recovery Twrp mode .. then connect it to pc and u will see internal srorage in pc...now u have to copy any rom to the phone and install it via Twrp ... Thats all

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)

Help bricked my p8 lite

What's your build number what version of supersu did you try to flash?
Shutdown your device, put your current build onto 'dload' folder in the sdcard and press the following key combo: POWER, VOL-UP & VOL-DOWN, it should enable automatic update process

Shut it down amd press those 3 keys combo.. upon seeing Huawei Logo and vibration, release the Power key while holding the other 2... That ought to do it

Man, your phone is badly bricked. If you don't have at least access to fastboot, then you're screwed.

Good for me to I have the same problem. I was trying to get to stock ( I have made it several times), but the last time was a fail... The whole process of sending firmware was ok. then a reboot and brick.
Now the huawei screen and the short vibration appears and shutdown.
I was trying everything.
In device manager the phone is displayed as mobile devices \ volume f:\ (drive letter)
in connected devices the phone is detected as
hi6210sft
Phone is not detected in fastboot or ADB.

I met this problem yesterday(I hope the identical ). Because I have two booting animations, one from Vodafone, I guess I shutdown early during installation. It just froze. Then it didn't boot and stock recovery didn't help
My solution needs some recovery software like twrp. Press three buttons at the same time until twrp mode. Copy zip file for SuperSU to phone or sdcard, then flash it. After that my phone works again.
You mentioned that you cannot start recovery. Try more. After installing twrp, starting it is quite annoying. Sometimes it just doesn't start or stock recovery starts. An alternative way is to go to whatever mode, and try adb or fast boot to reboot to recovery. Pressing button requires techniques which j don't have

I can't enter TWRP non combination is working for me. Installing firmware using dload from sd card also.

okay if non of these worked you can try flashing the whole update.app file by fastboot..
tools you will need
1- download the official huawei firmware from the official site
2- download Huawei Update Extractor
3- download minimal adb and fastboot
check the unbricking chapter of this thread
Note: to get in fastboot make sure you connected your phone to computer and press the vol down and power down buttons.. if none of these worked your phone is hard bricked .-. .. try opening the phone and reconnecting the battery worked with someone
if you need any help just pm me or replay on this thread hope that help you

Ok thx. I have already opened the phone to reconnect the battery
And then I was trying the combinations;
Battery connected vol- +power - Huawei logo and vibration and shutdown, no fastboot
Battery disconnected, vol-+power and connecting cable to phone - the same
Battery disconnected combination vol + vol - + ppwer, with sd card dload, the same
Battery connected combination vol + vol - power, sd card dload, the same
Any other suggestions?
The phone is recognized in Windows in device manager as mobile device as volume with a letter, I cant change the drivers to the right ones. I can't enter the storage it's unrecognized format.

Any other suggestions?

it is easy to suggest others.. I too advised you.. but today i am facing the same problem...
what I tried:
Reinstalling the same ROM using dload method
Upgrading to other ROM (using both dload and flashing 4 image method)
Downgrading
Restoring from the backup
At one point, the phone booted up all well except the Wifi Module... So I flashed another ROM and stuck again...

the worst thing that I don't have any connection to fastboot Each firmware installation method fails

yes, mine too... or I could say flashing succeeds but there's some problem with the boot partition... will get my phone today from the Customer Care and try again (if they can't repair).
you can try removing the back cover and unplugging the battery... that is one of the few things I will do today as I get my phone back..

ok made it back.. just flashed the boot.img from b594 (the one I was using when my mobile got bricked)... somehow made it back. But now I am having a problem with the battery. It doesn't charge when the device is switched on, only when the device is switched off... will see for few days, if there's problem will take it back to service centre again

I have already removed back cover and was trying to reconnect the battery to do clear run. But the only thing is discovered in windows is a driver for storage and I can't change the driver to ADB or FASTBOOT
Now I have connected phone w PC on adb devices I see only emulator-5554 device. In Device manager I see the storage as a Mobile Device.
Nope it was Bluestacks

Switch off your device and then connect it to PC but just hold the volume- key.. that should get you in fastboot mode... I did that and then flashed the boot.img of the current ROM. This should boot it up...

With this options is nothappening nathing just again is going to restart it every 2 seconds. Vol up + vol down + pwer button on more of 15 sec is going phone on power off.
I made relock on bootloader because I wanted to take it away waring: your phone is unlocked an can't be trusted ....

well...youve learn the lesson the hard way...you just cant get rid of that nag screen...
only thing left now ( i think) is to ... send it to huawei for ressussitation...
cuz at that point i dont think theres a method after loosing ADB access

Hi! Have you repaired your phone? If not, the way is easy. You need plug USB cable and hold Vol-. You will enter bootloader. You should again unlock bootloader with your unlock code. After that bootloop is gone.
It could be that phone won't enter bootloader. In that case you should power off phone. Possible needed to disassembly and eject battery cable. After that plug USB cable and hold Vol-.

I have same problem too, and I bought the phone from china, can not return back, any solution ?

Hi...what have you tried till now ?
try hold power off button for around 30 seconds...
then try VOL-DOWN+ Power while plugged to pc....

i had same problem today. Thought i have ruined my phone. But trying to rebooting the phone while using variuos options with power volume up and down accidentally succeeded. It was in my case holding power and volume button until stopped appearing reload every 2 sec, then i have released the power button while kept holding volume up button. And lucky i booted in to Huawei erecovery mode. From there I have booted my Huawei Nowa phone in to a normal boot. Hope it helps somebody.

Hello.. i have the same problem here. It keep restart after 2 seconds. When i push the vol up + power button, it goes to recovery mode. Ive done wipe/reset factory n wipe cache. And still i cant switch on my phone.

Huawei Nova Plus MLa L12 restart every 2 seconds..
When it restart too fast, im also can't enter twrp and fastboot..It restart too fast and vol +- can't detect..If anyone have solutions for this problem, please inbox me..Thanks.

Hello i have the same problem, I tried all the combinations of the power button + volume button + and volume button -, but nothing works, I even disassemble the phone and disconnect the battery, then connect the phone to the pc with the cable, but nothing works, are there any other proposals?

same here... any sugest?
