[Q] i9505 s4 button problems

hi, I have just registered and looking for some help if at all possible,
I have a galaxy i9505 S4 and recently the Home button seems to come and go, and the power button the same, and also the screen keeps lighting up every minute for about 10 secs, if i remove the battery I can restart the phone, and also the home button works to start the phone in factory reset mode, so i feel it might be a software problem rather than hardware.
is there any way to get the phone to reinstall the firmware, as factory reset didnt help
the phone is on orange (EE) UK
thanks for any advice or help given.

hi, thanks for the reply,
the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine.
on and off the power button dont work, and i have to remove the battery to restart it.
the screen just lights up every minute for about 10 secs as if it has a notification, but there is nothing there, it drains the battery to empty in about 5 hours.
cheers.
Jamie.

Reboot yr phone.

Connect phone to the computer and wait for the drivers to be installed. You will see blue or yellow indicator in left top corner of Odin, with phone connected to port: COM:x
Click START and wait until you see GREEN indicator [PASS], flashing is finished.
Then, it will reboot itself. U can unplug yr USB cable.

hi, I have just done upgrade and initialisation from Kies, and it redownloaded and reinstalled the latest software, took ages, and the button is still not working, so i guess it will have to go to the shop.
cheers for all your help, the button only works before the OS has started, as i can get into recovery menu.
thanks again.

mechanical or hardware problem
That seems pretty much a mechanical problem (button broken) or hardware issue (shortcut somewhere? could explain the screen problem...)

the buttoon does work, but only to get the phone into recovery mode at startup, so physically the button works, just not when the phone is powered into the android os.
Im a bit out of ideas.

It's a faulty button mate.
You don't need to use the home button to boot to recovery or download mode on the S4.
You can simply press volume up+power (recovery) or volume down+power (downloadmode) no need for home button at all.
This is why you think it works.

Not true, i have this same issue after opening Wanam.
The screen turns on if i press the home button but wont do anything else (exit from an app back to home screen etc)
About to re-flash rom and / or kernel
Edit:
Also
- the lockscreen wont work
- when connected to PC, the filesystem wont show up (used 3 diff usb cables, 2 diff PC's)

It's very true mate.
YOU DO NOT NEED HOME BUTTON TO BOOT TO RECOVERY, SIMPLE.
Your issue sounds different to the OPs.
If you refer back to his first post, he said his power button doesn't do ANYTHING.
"the home button just dont work, single click, and holding it in for the task manager dont do nothing either, but if i turn off the phone and hold the home, vol up, and power button, it boots into reset menu fine"
Yours works.

[Q] Bricked lgp700 after flashing cm 11.0

Hello,
I am very new to rooting etc. I rooted my phone a few days ago, unlocked bootloader and tried to flash cm11.0 with rom manager (cwmg) following this link:
http://forum.xda-developers.com/showthread.php?t=2521239
Unfortunately I didn´t understand the instructions well, so after wiping caches, instead of doing a full format I did a user data etc format (which i now think was a factory reset). Tried flashing, didn´t succeed.
Anyway, when I try to switch it on I only get the lg logo and then the batery charging thingy When I try to go to recovery mode with volume up power and menu button, my phone goes on a loop of lg and cyanomod logos untill infinity ( Have to take off the battery). Tried to use heimdall (as i have a mac) to flash kdz back to it, but phone was not recognized. On my pc tried the same, but again phone not seen. I can see it on my computer as an unrecognized external usb but cannot explore. Any ideas on what to do??
thanks in advance

As soon as you plug your USB into your phone, hold down the volume up (+) button and the power button and release them after holding them down for about 2 to 3 seconds. Then, install the USB driver for your phone with the LG Mobile Support Tool. Secondly, download and install the LG PC Suite program and last but not least, download the KDZ program. Install the correct firmware for your phone and make sure you select 'EMERGENCY' from the list on the top right of the KDZ program. Select your downloaded firmware file and start the program. If everything worked out, the program should crash after it's done and your phone should reboot. Disconnect your phone from the computer if it doesn't reboot and try to boot it up again.
You can find all of these programs along with tutorials on how they work by searching on either XDA or Google.

did forcing recovery/download work ?

the phone off usb in and buttons did it work ?

Actually didn´t work,I have drivers already, LG PC Suite program , and KDZ. Problem is my phone is not detected by pc, so kdz unzips and then says : phone not detected, with or without battery...doesn´t go into recovery mode with buttons, just lg and cyanomod logos...
I don`t know if this can b fixed.....How can you flash anything if it´s not detected....
I´ll give it a try again tomorrow, without trying to enter recovery mode....but tried lots of buttons combinations and wasn´t working

Press these buttons
volume +
,volume -
home button
together with the power button
release all buttons except power button when you get a vibration
release the power button immediately after the lg logo has appered
this should let you get in the recovery menu

[Q] Bootloop, no recovery - how to shutdown the phone

Hello,
I'm on LG G2 Stock Rom on Kit Kat (4.4.2). The phone is rooted but no custom recovery as I just need "root" to run Titanium backup.
Yesterday, I attempted to update the 1 XML file to increase speaker volume. Upon restart the phone will stuck on LG logo and does nothing.
I can access download mode. So now, i'm downloading LG Flash Tool and KDZ file for my phone to flash all back to stock.
The question is now: how do I turn off the phone? Pressing power button will simply restart the phone - it never goes to off.
Another question: if I don't install any custom recovery, is there any stock recovery installed? When I attempted to go to recovery (by pressing volume down + power method), I was presented with Factory reset questions. I clicked OK twice and then Android logo appears (it seems like it's attempting to really do a factory reset) and then phone reboots.
If I can go to stock recovery, I hope I can access the storage inside and redo what I did yesterday.
Anyone can help? Or share some knowledge?
Thanks

The latest software upgrade was installed by using LGMobile support tool. I'm back to stock and finish with ioRoot.
Now, going to use AutoRec to install recovery (better to have custom now, so if this happens again, I have a way to access my phone data).
No answers given but it's no longer urgent now. Still if anyone found a way to off the phone when boot looping other than waiting for battery to run dry, by all means, please reply the thread.
Thanks.

Unplug the USB cable if it's plugged.
Hold power button for like 30 seconds straight.

To turn off phone ,just push volume down and power button same time for like 7-10 sec, it will be like restart , but keep them pressed until screen shuts off again (it will take less then 1 sec). Thats all

I didn't time 30 seconds, but I did press power button for a long time. Is this method for when you can use the phone? Mine is during boot loop.

I can't say for sure now, since I have my phone backed-on. But I sort of press these buttons for a long time at the beginning (when I wasn't really sure how to go to recovery mode). But good to know about this - (for next time ).
thanks both!

Only method i know to completely shut down phone in any situation is what i already wrote in last post.

Agreed.
it happen to me too when I try to install MIUI ROM.
Pull off USB cable and long press power the power button

Thanks. I'll remember this, if I got unlucky and stuck in booth loops.
For now, I installed recovery, so hopefully if this happens, I can still access my internal folder and do the require changes.

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?

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

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)

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 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.

[Q] ZC520TL - Recover half-brick Zenfone Max 3

Hello to everyone,
I received a system notification this morning which was telling me that there was a new software update for the Zenfone 3 Max. So I've clicked on it to update the system, and, during the update, something went wrontg and it "crashed", rebooting in a strange korean (?) screen:
Now I can't boot properly the Zenfone and if I try to move inside the screen it just changes some english text from eMMC or FM to BT or GPS. It's like it is doing a device check and something isn't working.
It can't be turned off, so I just let the battery go dead to see if this would fix the issue.
I've charged it while it was switched off, and after a couple of minutes it turned on with the same korean (?) screen. I've also tried the hard reset by keeping pressed the power on button, but it only went off.
The last thing I've tried is to connect it via USB on my laptop while it is in this strange screen and checked that is recognised by the ADB. I've never unlocked the bootloader or ever rooted this model, so the response of the command "adb devices" is a model and the text "Unauthorized".
Is it something that I can actually do? I'd like to try an hard reset or force it to go in recovery mode and try to reinstall the firmware... but since the device is "unauthorized" I'm not sure that it will let me flash the firmware...
Do you have any advice on how to handle this situation?
Thanks in advance
(I do apologize for my grammar mistakes)

My English is really really bad, so try to understand this
Frst if ur phone is hang or stock in any ways u can reboot or power it off by pressing the power button for atleast 10 sec. Press and hold.
Second u can reinstall the firmware in any case even if ur phone is dead.
Frst u need to install the usb driver

Then u can reinstall the firmware using the following files

First of all, thank you for the explanation, as far as I've searched this seems to be the "factory mode" screen of the asus zenfone max 3 with the chinese language setted... And the fact is that this mode is used for test purposes only, in fact if I randomly choose any option it just seems to test a random phone function. Anyway, I've tried to reboot it by choosing the 8th option, which is supposed to reboot the phone normally, and it kept on going in that screen again. I've also tried to reboot by forcing the reboot via (Vol Down + Power) buttons together.. and for my bad luck it still resets in this "factory mode".
I watched the video and not sure about it because I'm not familiar with SP Flash Tool: does my zenfone needs to have the bootloader unlocked? or it should have been rooted? Will I be able to flash the firmware while the phone is in the status, even if in ADB devices it is shown as "Unauthorized" ?
I'm asking all these questions because I've never done any firmware operations on this smartphone, I've only made ordinary system updates.
Thanks in advance for your patience and your attention!

Pressing volume down + power is going to that screen. I dont know if Chinese or Korean
Pressing volume up + power key for default recovery mode screen,
Press and hold the power key is for normal boot.
I dont know if zen3max need a bootloader unlock.
Because im able to install a custom recovery in my zen3max and my phone is rooted and im able to install back the stock recovery so i dont get any trouble Everytime i received a notification update.
Well if u r worried. Get another smartphone and use the google translator with the camera to translate that Chinese language on ur zenfone 3 max. Maybe u can find the format option or clear cache blah blah blah.

When you said that volume down + power key is the combo of keys to press to go in that screen... it kinda rang me a bell: recently my smartphone fell and it got damaged on the right edge, causing the volume down button to get inside the cover, and now it is like unpushable... I've never powered off my zenfone until I had to do this system update. So I thought that probably there isn't anything wrong with the firmware, it just keeps going in factory mode each time I try to power it on due to the fact that the volume down seems to be pressed all the time. So I decided to contact the ASUS support team to give it to them and let them repair the buttons.
Thanks for the info!

so must be thats the problem boot looping​ in to that screen because the volume down is broken. I guess.
Well thats the best u can do to fix it.
