[Samsung Galaxy Grand Quattro] :
​

This thread is for Project Engine Kernel users to clarify their doubts or face any difficulties in using the kernel.Any Recognised Contributor who would like to help me to manage this Q&A thread is greatly appreciated

Requirements:

Galaxy Grand Quattro Device(Obviously)

Logcat(It would be easier for me or the RC to spot the issues easily

Do speak politely with one another.Its part of respecting each another and the XDA rules

If you can help,try contributing to fix issues that other users faced because we are all here to learn

FAQ:

Why is my phone's battery discharging so fast?

- Check that the amount of apps running on your background process.If there is too much applications running,i suggest you use greenify

Why is USB OTG not supported in Galaxy Grand Quattro?

- Somehow Samsung disabled USB OTG in Grand Quattro Device and I am trying to reverse-engineer the process of how they disable it and how i can fix it.I know this is quite a hot-topic among users but seriously its not as easy as you think.There are lots of consideration when coding OTG because if not handled well,it could be pose risky problems

Where do i download the zip file?

- I have imported the thread to XDA DEVDB Project so now all zip files are under the Downloads tab.You are required to use the browser or when you are in Tapatalk,click view on Web to see the Download files

What does the governor and I/O Scheduler do?

- Well there are already lots of hardworking chaps in XDA writing guides to help users.One of them is here and another one is here.Dont forget to thank them because writing this guide takes a long time for them and their hardwork should be rewarded.

What is the difference between ARM and Linaro toolchain?

- ARM toolchain is the basic compiling toolchain used for kernels and ROMs but Linaro toolchains is full of optimisations that could really make a big improvement in the kernel such as battery life and performance.Over the years,many users were elated over the speed and battery life that their device kernel can achieve through the Linaro toolchain and it is now the most well-known toolchain in XDA and other places of Earth.Well,fear not,Project Engine Kernel is compiled using Linaro GCC 4.7.4 Toolchains and therefore,you will be amazed with the difference between the stock and custom kernel.

I know there are lots of question that i cant answer all so post them here if you have enquiries

[General Questions and Answers] M_Maha:
Will the play store and play services work if I sideload them as user apps?

I currently have them as system and they are constantly running in the background and use battery and overheat the phone.:(:crying:

Will this behaviour top after I turn them into user apps?

:confused:
​
[General Questions and Answers] Ragkhuza:
Don't attempt to move google playstore or google play services as it might become a serious trouble. If I were you I'll use DU Speed Booster or SD Maid to stop apps from running at boot and save battery.

Never underestimate a kid whose poor in cash but rich in time.
[General Questions and Answers] M_Maha:
Your suggested methods will fail because even if i stop them at boot they restart afterwards

But if I install them as user apps will they work?

Moving them will not make the system unstable,I suppose ;but the apps should run
[General Questions and Answers] M_Maha:
I installed the play store and play services user

Then i opened the play store and it closed without any mesage of FC or anything

then i tried the play services i.e. the google settings app and it worked

Can anyone tell me whats going on with play store and why it closes

Anyone who is willing to try this and develop a solution?
[General Questions and Answers] Ragkhuza:
Install the playstore to System again. Google playstore needs access to system in order to work properly.
[General Questions and Answers] M_Maha:
May be we will convert this to development thread.

We"ll try to make play store run as user app

or atleast find the reason why that wont work

:silly:
[General Questions and Answers] pinkLeviosa:
try to greenified it..

to do that download and install greenify in the google play store.. for free

what it does it hibernate a app that prevents suddenly unexpected background processes that eat battery. If you open a greenified app it will work normally ..:)

just tryin' to help, so i hope it works:good:
[General Questions and Answers] M_Maha:
Already use it

Thanks but I already use that since i bought the phone! :p And it works too i just made this thread coz xda didnt allow me to post in development threads until i post 10 posts

[HTC One X+] shqrif:
sorry if that a question is noob . but the thing is that i flashed viper x+ 2.0.3 that comes with Sebastian fm kernel . to tray swipe 2 wake feature i flashed the elite latest kernel & it goes like charm . After receiving 2.1 OTA I tried to go back to Sebastian kernel . so i use the venom flasher to flash the kernel , recovery & kernel modules ( Kernel N Recovery for 2.0.2 & up That posted on viperx + page) . but i lose the wifi/signal !!!!!!!!!!!!

the Q ..... How i can flash the sebastian kernel without losing the wifi/signal
[HTC One X+] ivicask:
Its because kernel flasher doesn't work properly for HOX+, as when it reboots to recovery phone is not visible by pc for like 1 minute and it failes to push modules.

http://d-h.st/d3U

Use this to flash it for now, we will upload fixed Kernel flasher also..

Is there any way to use the Universal as a portable home videochat machine? It seems like a perfect app for this gadget, especially with the 'face camera'. It would be great to chat to my girlfriend over wifi on Yahoo IM or suchlike without having to lug my lappie around every night. Also, the fact that the Universal could alert me when I have an incoming call would be great. I have tried the built-in Messenger service, but this only supports text chat (with no file send either it seems?!).

Apologies if this has already been covered, but I could not find anything via search. :roll: [/b]

Please be more precise on the file you downloaded, and link.

Then describe what you have done.

Have you unpacked? With which program? Copied files to which sd card? Formatted how? Into which folder?

How did you install?

[One (M8) Q&A, Help & Troubleshooting] Niorun:
Hi,

I need some help, my phone doesn't boot anymore and i can only get into recovery!

I was on TWRP and ARHD (latest versions) and i wanted to try out PhilZ recovery, everything went well except when i wanted to format my sd card and reinstall ARHD. Normally my phone should boot up so i can place the .zip file on the virtual sdcard. That is where the problem starts, it doesn't anymore it hangs on the HTC logo (boot animation) and stops working.

I can reboot the phone with the power button + volume up and when the screen turns black press volume down method. But that is it really!

When in recovery and select fastboot (usb) the phone won't show up on my computer. When it try to mount the sdcard from PhilZ recovery i get a cdrom drive mounted somehow. And if i select the reboot function from PhilZ recovery i get a message saying: 'Root access is missing/broken.' I can select 'No' or 'Yes - Apply root (/system/xbin/su)' both options won't change a thing...

I have a nandroid backed up to my PC, but that isn't of any help either.

If anyone has any suggestions or solutions?

Thanks in advance,

[One (M8) Q&A, Help & Troubleshooting] EddyOS:
Use adb push to push the nandroid back to your phone to restore it. I'd also go back to TWRP to make sure it restores correctly
[One (M8) Q&A, Help & Troubleshooting] Niorun:
Just to be sure;

- Flash TWRP (fastboot flash recovery recovery.img)

- Push recovery.img (adb push recovery.img /data/recovery.img)

- Restore (Run restore from recovery)

I've collected the recovery.img from the backup folder and placed it into the adb/fastboot folder.

Is above correct? I don't want to mess it up further. :rolleyes:
[One (M8) Q&A, Help & Troubleshooting] EddyOS:
Not quite...

1. Flash TWRP (fastboot flash recovery recovery.img)

2. Once in TWRP, use adb push to push the Nandroid to your phone (adb push <foldername> /data/media (I think, never had to use it so could be wrong))

3. Once pushed, restore backup in TWRP
[One (M8) Q&A, Help & Troubleshooting] Niorun:
I placed the folder into the root backup folder for TWRP, which is /sdcard/clockworkmod/backup/<foldername>. It's copying the data now, afterwards i'll restore it.

I will let you know the outcome.

Thanks so far!
[One (M8) Q&A, Help & Troubleshooting] EddyOS:
That's the CWM recovery location, you have to put the TWRP backup in the TWRP location (from memory it's /data/media/TWRP/<serialnumber>/BACKUPS/<nameofbackupfolder>) otherwise it won't be seen
[One (M8) Q&A, Help & Troubleshooting] Niorun:
Haha yes, i had just figured that out. My mistake. ;) Thanks for pointing it out anyway.

I've not been clear, just to clarify...

I booted PhilZ recovery and made a backup before flashing it.

That is why i mixed up things all together, i've now reflashed PhilZ and restored the backup i've made.

The restore procedure worked fine now, and my phone booted up.

I am still not aware though where it went wrong... But, I am glad i've got it working again thanks for your help!
[One (M8) Q&A, Help & Troubleshooting] Niorun:
Problem is solved, this thread can be closed or whatever. :good:
[One (M8) Q&A, Help & Troubleshooting] EddyOS:
Might wanna highlight what you did just in case someone else has the same issue...glad you're working, though! :D
[One (M8) Q&A, Help & Troubleshooting] Niorun:
Hopefully you have a backup of your nandroid backup on your PC or another storage.

Here is what i did to solve it.

1. Reboot phone in fastboot, connected the USB cable.

2. I placed the backup folder in my sdk folder, and copied the backup folder to the original restore folder for PhilZ Touch. Start command prompt and go to your sdk folder. Enter the following command: adb push <backupfoldername> /sdcard/clockworkmod/backup/<backupfoldername>

3. Reboot phone in recovery.

4. Select 'Backup and Restore' then select 'Restore from /sdcard'.

5. Select your <backupfoldername> and restore!

NOTE: If your backup has been made with another recovery than PhilZ Touch its restore folder is different! Be sure to write down the correct one or the backup isn't visible in recovery.
[One (M8) Q&A, Help & Troubleshooting] r0flcopter:
Well, this is awkard, after the last flash, it booted up, and I got trough initial setup, and I rebooted, and it seems like the problem was an excruciatingly painfull boot time... This post can be deleted if necessary :)

My problem that no longer exist

Hey! I have the international version of the HTC One M8 2014.

I have the exact same problem as the OP except for one more... I do not have a nandroid backup. I've been busting my ass of on google, and I'm not quite sure of what I'm looking for. It's a bit of a mess with versionnumbers and such. I happend right after i reflashed my HTC with Revolution from Cyanogenmod 11. I entered blindly into the Team Win recovery, and deleted the internal storage. This did not seem to work, and i was stuck inside the splashscreen, I then used the same method as OP to get back into recovery, and followed a guide where i wiped system data, cache (i think), and dalvik cache. This seemed to work (with the Revolution ROM) untill i used Titanium Backup to backup my apps, and restarted. This got be back into the splashscreen. I've then tried to reflash Revolution, but to no luck. I'm still stuck in splash.

I would very much appriciate if someone could help me out here!
[G2 Q&A, Help & Troubleshooting] Rogybear:
Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp

I was previously Rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.

I followed http://xdaforums.com/show....php?t=2476972 method, and got back to Download Mode.

I am currently in the middle of returning to stock through http://xdaforums.com/show....php?t=2432476 using the .TOT method.

I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.

Therefore I cannot change the port to COM 41 to flash the .TOT file.

I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?

Some more info about the phone:

it's the D801 variant but its on Wind (Canada) not T-mobile

it was previously Rooted

it did not have any recovery software installed

no roms had been flashed previously.
[G2 Q&A, Help & Troubleshooting] shark_max:
Try to restore your phone using the official LGMobile Support Tool. Just switch on normally the phone, plug it to your PC and wait for your kdz to be downloaded. Once it done, it should install the kdz by itself. Then factory reset your phone (if needed) as it should ask you some pin/password.

Hope it'll help you as it did for me!
[Galaxy S III Themes and Apps] justaguyh:
hello to all.

I've been searching for the past few days for a good lock-screen replacement.

overall i'm ok with stock lock-screen. i don't like to much to flash roms.

I've tried slidelock locker and it's probably the one that's get the closest to what i'm looking for.

I've got a few demands from a lock-screen.

1. wake up phone on notifications - SMS e-mail, Facebook etc.

2. show notifications on the lock-screen + preview of the notifications.

3. lock/unlock sounds are important to me.

4. disabling home button.

5. not too much memory consuming.

slidelock has some issues with the home button and sounds but it's reasnoble.

currently i'm using go locker, but it doesn't wake the phone and the panel of the sliding apps menu has only 3 options - unlock phone, sms, phone calls.

tried dyanmic notifications but it doesn't show a preview of the notifications.

feels like the iphone lock-screen (hate to admit) is just what i need.

any help would be appreciated.

thnks.

LockerPro
[Galaxy S III Themes and Apps] justaguyh:
thanks for your suggestion.

however, as far as i can understand, slidelock locker is from the same company. it's the 2nd generation of the lockerpro or something like that. so no sounds on lockscreen and i think it's battery consuming...
[Galaxy S III Themes and Apps] lsalamun:
Every locksckreen app will use ram and battery because it must run in background, it doesn't integrate into framework, if you want aosp style you can install xposed module aosp locksckreen, it works great but it has not options, it integrates into framework so it wont consume battery or ram.

Galaxy Locker by X-Andev

I like this one. I guess it has everything you want. Give it a try

Or Locker Master. I test this one right now and I like it :)

Or check out AcDisplay. Sadly its not compatible with 4.1.x

[HD Mini General] ottobald:
Have here a HT mini (PB92100) SPL-1.07.0000 with error code "!MicroP(LED) error(0x00)! Expected(0x1B)"

When I start the phone normal the HTC logo appears on a white screen. This lasts for about 1 minute. After that the display goes black (screen still on in dark grey) for about 10seconds. Then the WM 6.5 start screen appears(preparing for first use). The bar on buttom of the screen runs until 100%. It lasts in this state until the battery is empty and shut down.

What I have done so far: Hard reset (vol+ und vol- pressed and switched on). No success. Starting in bootloader mode and tried to connect to PC: no connection. Prepared SD-card (2 gig-SD) with latest rom "HTC HD Mini_RUU_Photon_HTC_GER_1.36.407.1_Radio_Signed_32.2803.05.06_0.63.05.36_Ship.exe" and started in bootloader mode (vol- and power) - nosuccess.

After some tries I got the unit running for a short while (HTC logo with desire.... and sound, windows started up - but extremly slow.

Also with the PC connection I had a ping and win7 tried to install a driver for the phone but didn't find one.

One remark: There is a small spot broken from the glass of the touch screen right bottom side. But the display is absolutely fault free. Could this be the reason for the "!MicroP(LED) error 0x00"? Any help is appreciated.
[HD Mini General] iPlasm:
I wish I could help you, but I'm not sure what caused this.

Have you tried other WM ROMs that made for your phone officially?

and when did that error happen? after broken?
[HD Mini General] ottobald:
humidity issue

Meanwhile I have solved partly the problem. WM6.5 starts and all the menues work so far. Problem was that the phone fell into water and hasn't been dry enough before switching on again. So I disassemled the phone, took out the main board and found some dirty spots around the battery contacts and even around some connectors. Cleaned all this and the phone starts now in windows. Touch screen works, display is ok. Sound comes out of the speaker and the camera works too.

After I reassembled I found some further issues: vol+ button doesnt work. Even WiFi doesnt work. Only very very close to the router I get 1 bar for WiFi. I still can not boot in the bootloader - maybe a problem of the not working vol+ button. Tried to remove the second board but wasn't successful. Do I have to remove the screen to remove the screws for this second board? Any help?

[HD Mini General] ottobald:
WiFi

Thanks again for the help. I managed to lift the second board a little bit and found nothing what caused the remaining malfunction. Then I opend the shielded boxes on the mainboard and cleand inside two additional spots which ware a result of the dryed water drops inside this boxes.

Now the unit runs as expected. vol+ and vol- works, !MicroP(LED) error has gone, and wm m5.6 runs like a scharm. But one thing is left: WiFi doesnt work properly. Still only 1 bar of the WiFi router. Even direct beside the router. Does anybody has a hint regarding the Wifi?

There is a blue and a grey coaxial line between the 2 boards. Assume the wifi chip is on the mainboard and the antennas on the second board with the keys. Which one of the coaxial lines is for Wifi? The gey or the blue one?
[HD Mini General] iPlasm:
I'm not good at hardware for htc hd mini, and the developers or whatever called are gone here! nobody left, so all you can do is at your risk or you should ask the others from your friends or there can be something that grey or blue is line for wifi, from my laptop's wifi were grey color, maybe this should be grey too. blue are usually for connection line cable, and for wifi and antenna or satellites were grey colors.
[HD Mini General] ottobald:
Thanks again!

Simple solution for this WiFi issue: Didn't reassemble the back cover of the second board. Back cover has all the antennas integrated. So after reassemble of the back covers the unit runs perfectly.
