Firstly safemode only allows core apps to run that came with the phone such as phone, calculator, calendar etc. that's why your apps wont open.
next for the massive data transfer I think you have a memory controller problem or a battery problem I suggest RMA or contact LG for repair
it also could be a rouge app that you install that is causing everything to crash.
Try transfer that large file on safe mode as it disables all apps except stock apps

The problem is safe mode does not work, i can launch any app on safe mode (see video watch?v=ycjK_333a70).
Is it critical?

Your bootloader is the oldest one available.
For me safe mode works without problem, ( I am using my AOSP KVT49L rom), but on Stock KOT49H I can start firefox but it chrashes. It does not work. however the apps missing from the appdrawer, but their shortcuts is on the homescreen. Some of them works and some of them crashes
I bought mine one week before crhistmas. I used it 100% on stock till february.
During that time I have not experiened any other the issues you have.

[Q] Help, HTC Desire HD plagued by Google Navigation self launching

Hi all,
have been having major trouble with my HTC desire HD, a while back it started launching Google Navigation of its own accord and now does it so frequently my phone is as good as a paperweight,
It normally pops up and starts by saying I need to go to settings to turn on my GPS to allow Google Navigation to work, thing is I dont want it working, I didnt open it
I tried leaving on the GPS to see if it would leave me alone then, but it doesnt it keeps launching telling me to buy a license to use Google Navigation
I saw a thread online about deleting the maps and data that Google Navigation uses from the phone when connected to computer via usb, tried that, it still launches itself, instead telling me I need to download the maps that I just deleted. Have since let it redownload the maps, left GPS on, said yes to everything it asked and it still wont leave me alone.
Whenever it launches it shuts down whatever I was doing which is infuriating, and now does it every 30 seconds or so, even when the phone is locked it lights up showing the lock screen because that app has started itself again
I will do anything to be able to delete this app and get my phone back
Do I need to root it? Will that let me get rid of this #bleeping bleeper#? I have never rooted a phone and am not sure about how to do it or whether I need to downgrade my software, or how to do that. Hence the plea
I have read the thread here:
http://forum.xda-developers.com/show....php?t=1377119
and was going to give the Advance Ace Hack Kit a go (will it let me delete Google navigation if I do this?) but was unsure if it would work on my phones software and I dont know how to downgrade
My phone (HTC Desire HD) is running:
Android version: 2.3.5
HTC sense version: 3.0
Software number: 3.12.61.5
Kernel Version
2.6.35.10-g931a37e

Any help would be much appreciated!!!

I have the same problem as you describe. The only difference is that I have my DHD rooted and it happens on both gingerbread based roms as well as ICS Roms. I Tried to get rid of it by formatting the sd card and doing the superwipe script and reinstalling different roms. Everytime it happens again. I have no idea how to get rid of this. It is as if it was a Virus but i really doubt it since i formatted my phone as far as I know, unless it can be somewhere where superwipe doesn't clean.
If any1 have solution for this please share.

Yes you will need to root your phone, no need for other rom. Check on HTC website how to unlock your boot loader and then on XDA forums of how to root your phone. Once that is done go to andoid market and download "AnTek app manager". Using that android app you will be be able to freeze Google navigation without having to uninstall. It won't even show up any where on your phone except in AnTek app manager under frozen tab. I did this with all HTC unwanted apps.

[Q] RK3188-based N90FHDRK: Corrupt Flash Memory???

Dear experts
I am very new to Android, and this N90FHDRK is my very first Android device ….
So for my N90 I am using Glassrom V2a, and I have tried several others as well.
Since the last 2-3 weeks I face strange problems:
- Tablet does not boot
- Tablet does not switch off (goes off only after pressing on/off for 30sec)
- Invalid unlock-code
- Battery-status unknown
- Disappearing applications and wallpapers
- Apps crashing
- ‘cannot mount /cache or /data’ in CWM-mode
Of cause reinstalling and wiping everything helps, but the problems come back once a day … Once in a while just reformatting /data helps.
What could be the root-cause:
- Some application corrupting parts of the (internal 16GB) flash-memory – but which app? I might even restore the same app again and again
- Corrupt flash-memory (with cells loosing data, or not writable)
- Memory-controller
Looking at the internal 16GB ‘corrupt flash-memory’: in the ‘PC-world’ I would run some ‘chkdsk’, and I also know that during low-level-formating bad blocks are recognized and marked at ‘bad’
Is something similar available for Android or the underlying Linux operating system?
Even if I manage to identify a bad-block, can I mark it as ‘bad’, and would this marking survive a restore?
Of cause I could simply send the tablet back to China, but that brings other problems and potential risks ….
Thank you for your help

Too bad, It seems I am quite alone with this problem
+1. If anyone has any expertise with this specific tablet that would be greatly appreciated. I think the problem we are facing is similar and that is I want to go to stock and which the .img file is released, its just the matter of using it. I am used to CyanogenMod for my nexus 4 where i would simply have the file already signed and used using recovery mode. But this .img file is a lot different and if someone could point in the right direction on how to do it that would be wicked. P.S. its so unlike my Nexus 4 with the actual seeing the android open and picking bootloader and all that, its jus a black screen and the computer recognizes it.

General ROLL-UP -Joying 2GB - Sofia ( Non MTCB/MTCD )- Tips, tricks and mods

There is getting to be quite a bit of information to look through when looking for tip/solutions related to the new Joying 2GB / Sofia units. Since this is not a MTCB or MTCD unit, the threads seem to be scattered all over and very difficult to find in searching. I have seen roll-up threads for other units, that contain information such as ROMS available, tips, tricks and useful information. Kind of a "one stop shop" for the newer Joying HUs. If you have useful software, mod, tips, customization's, get something to work, etc please post here and I can include.
CPU Information - Rockchip Sofia x64 C3230RK / mali 450 GPU / Up to 1.2Ghz / 4 core / FYT5009 SoM - rated to run at up to 85C. My particular is unit clocked at 1.04Ghz.

Latest ROM - Current ROM can be downloaded from link on the Joying blog site.

Android 5.1 Discussion about the Feb 22, 2017/March 5, 2017/March 15, 2017 updates:
https://forum.xda-developers.com/an...d-units/joying-intel-update-feb-22nd-t3561285
People have experienced issues with the Joying Launcher (UI3) after the update. This seems related to having other packages (google voice search ) installed prior to installing the ROM. Install time 25-35 minutes.
Recovery from non-bootable system - Without being able to access recovery, about the only solution is to reload the ROM package. Unzip ROM to SD card or USB stick, put in unit (GPS Maps slot, if using SD card ) and press the 'recessed' reset button. The unit should find the update and reload the ROM. This will wipe your data, but does leave the apps. If you use titanium backup, and have a backup, you can restore your data fairly easily. See blog article above for step by step instructions.
Root - Unit comes with root accessible in adb. SuperSU can be installed easily. There are 2 methods for installing superSU. The first method is an overwrite of the boot partition with a pre-rooted image. Problem here is if future upgrade makes boot partition changes, this method will overwrite with an older version. I recommend method 2, which modifies the existing boot partition ( need source so I can provide credit ).
https://forum.xda-developers.com/showpost.php?p=69648860&postcount=84&nocache=1&z=8361786322568856 (over-writes boot partition / may not work on Joying Feb update )
https://drive.google.com/file/d/0B4qmTV7N4JliSjZMdGg3Z18wbkU/view?usp=sharing ( modifies existing boot partition )
OS & Google Apps - Android 5.1.1 ASOP based w/ pico installation of google applications. Voice actions are supported with installation of 'Google App' from play store. No support for google search talk back.
Recovery- A recovery partition is present but does not have any type of graphical UI. It does look like a complete stock android ( command line ) recovery, but no access using USB is available. It maybe be possible using PC-PC OTG cable.
SD Cards - I have not heard of any sdcard size limitations, up to 200GB have been reported to work. Must be formatted as FAT32. NTFS, exFAT, and ext3/4 do not work. You can format a USB stick with ext4 and it will work fine.
Google Voice Calling - Stock BT dialer crashes when being called from google applications ( such as google voice search ). Workaround is available.

Enable OK Google from any screen - https://forum.xda-developers.com/showpost.php?p=72447390&postcount=968
Bluetooth Tethering & BT Settings - Bluetooth tethering, connects instantly, very reliable connection, works great for streaming music, gps etc. Saves phone battery vs WIFI hotspot. Limited to ~2Mbs ( slower than WIFI sharing )
https://forum.xda-developers.com/an...elopment/bluetooth-settings-launcher-t3504526
(also good discussion here on the effects of process killing when entering standby )
Difficult to pair BT devices - Forces device pairing into database - Device pairs normally once HU thinks it has connected previously. I was able to pair TPMS, keyboard, etc using this method(s).

https://forum.xda-developers.com/showpost.php?p=70325711&postcount=403
Apps not working after resume - The joying code will kill most applications when going into standby. This is really bad for apps that are supposed to be run at boot and background process, as they are not restarted when exiting standby. Symptoms include, widgets not updating, apps not getting GPS lock, process show running but background services are no longer running. This can be fixed by installing an updated apk file in /system/app/Sofia-1-C9-Server-V1.0 which removes the task killer. Also the key/button mods V2+ (below) will remove the task killer.

Immersive Mode / removes top navigation bar - No app needed - Full Screen on apps you choose, can be set from adb w/ root. Argument is list of package names separated by "," or "*" for all apps. ( survives reboot )
Specific apps:
settings put global policy_control immersive.full="com.google.android.apps.maps,com.pandora.android,com.spotify.music"
All apps:
settings put global policy_control immersive.full="*"
Clear / back to default
settings put global policy_control immersive.full=
Change Overscan - problems touching the corners, changing overscan can help:
https://forum.xda-developers.com/showpost.php?p=71492575&postcount=169
Phone/Tablet view on apps - No app needed - Change from 160dpi -> 161dpi gives "phone" view of many apps instead of "tablet" with no noticeable size change to other things. Done via adb. Requires reboot to take effect.
> wm density 161 # ( phone mode apps )
> wm density 160 # ( original tablet mode apps )

Yes this is really needed. A FAQ with overview links and tips in just one post
Some people mentioned it was possible to boot into a restore function from a memory card with the update zip. If true, do we know what the exact process is? Any keys need to be held down?
Update, verified this procedure works:
sonof said:
I did recover from endless Android logo (resulting from trying to root with Joying HU root.zip found in this thread).
I did the following:
Put latest Joying update files to microSD card and insert it to GPS slot. Press and hold both reset and power buttons. Once it boots continue holding reset button.
This lead to automatic install of Joying update files and my HU was back alive but I hate the Joying company for not providing means to enter recovery and a complete ROM.
Edit: For me it did not ask if I want to update or not. It just began updating automatically. In contradict to the post above. But I was unable to boot to Android when I tried this.

My VW has reverse parking sensors. Does it not support those?
Just installed this unit. Speedwise it's night and day compared to my old Erisin (1gb 3188). Display is nice and crisp. Bit of a fiddle getting it mounted because of all the crap that needs to be stuffed behind it, but after some swearing and elbow grease I got it secured.
From the instructions, I cut an orange wire because I don't have a backup camera. I do however have optical parking sensors. On my Erisin this was supported (it showed a car model and visual indicators on screen). This unit doesn't appear to have this function. Can anyone confirm? I still get the beep from the speakers, so it's not really a big issue, but would be nice to know.

anotheruserx said:
I'd like to work on this one.
But I have two questions;
1) did you manage to get any logs of how it failed?
2) When you made it unbootable, what was the exact procedure you used to recover the unit?
Click to expand...
Click to collapse
I didn't get any logs, as I couldn't connect to it until I reloaded the ROM. If I was able to make a USB connection, at least I could have looked at the logcat.
Procedure to recover: Insert USB drive with ROM, push recessed reset button, wait 30m for ROM to install, set up apps again. I have this procedure down pretty good. - The joys of playing with the system partition without USB access or recovery tools.

Actually, it turns out it does, however only when there's an obstacle (hopefully we can change this). Yesterday I only tested while stationary. Today I used it while driving, and noticed that whenever the sensor picked something up, the unit does actually display the sensors. It feels next to useless for me when it only shows on beeps, but at least we know it's there.
Well, that is the way my discarded Newsmy worked. Takes getting used to, but you then again you don't really need confirmation that "nothing" is in your way
Will need to think about this then, thank you.. Cant make up if I want this or the Ownice C500.

After updating to the January firmware parking sensors are gone completely.
edit: enabling "radar" is the solution
Installed supersu (like described in this thread) yesterday and updated it from the play store. Worked fine.
Then I installed Viper4android, also from the store. I didn't expect it to work, but it does! Driver installed, and after a reboot it does exactly what it's supposed to.
Also installed Nova Launcher and set as default home. No issues with that so far. I have not frozen or uninstalled any of the original launchers.
On my Joying unit 130N2 (8 inch unit for VW) the backlight on the display does not work when it is cold. We had minus 8 degrees centigrade here and it took more than 10 minutes before the backlight came on. The radio is playing music and it is actually possible to change channel as long as you know where to touch the monitor. Today it was 5 degrees and it took only about 3 seconds before the backlight came on. I wrote Joying about it and they confirmed to me that there was an issue with 8 inch models for VW. They told me that they were working on a completely new firmware that would fix the problem. I told them that to me it seemed to be a hardware problem and how they wanted to fix that with a software. Their answer of course "No worry my friend ......". I told them that I wanted to return the radio because a radio that doesn't work when it is cold is useless to me. They told me that I would have to send it to China so that their engineers could investigate the problem. I then told them that I had bought it from a German website and it was delivered to me from Germany so if their wanted it to be sent to China then they would have to pay me for it - in advance. They told me that their warehouse in Germany did not accept any returns so it was impossible for me to return it. Then I opened a case with Paypal for selling defective merchandise. Then suddenly their warehouse in Germany was accepting returns. I had put this text also on the Joying Forum, but of course they deleted it. So when dealing with Joying and in case you have problems my advice is to be very tough on them otherwise they will BS you.

I have the same problem on the same unit. With the car headlights off, backlight is dim when it's cold, but gets brighter when it has time to warm up. And when the headlights are on, the backlight isn't on at all until it warms up.
I thought about writing Joying about it but I expected the kind of response you got. Plus, I've had my unit for a few months already so a PayPal claim isn't an option. Please let us know if you hear anything else about it from Joying.
Hi Joshnat,
Yes we have the same problem. Sometimes I can get mine to light up by turning the headlights on and off a couple of times. Are you sure that you cant make a Paypal claim? As far as I know you have 180 days.
Anyway, you should write to them and let them know that you know that many others have this problem.
Regards
Kurt

You may have a faulty screen, my first one did something similar and wasn't very responsive to touches. I returned and my second unit was like night and day with how much better it looked and worked.
Has anyone got a factory backup camera to work? I have a 2015 Camry and right now I have the older Pumpkin rk3066 and the place that installed it hooked up the factory backup camera. I got my new Joying hu yesterday and am going to install tomorrow myself. I'm really hoping I can use my factory camera with this head unit also.

Quick tip:
You can adjust backup camera brightness, saturation and contrast by touching the screen while backup camera is on.
Is there a trick to putting in the sd cards? Mine won't click in so it won't mount.
Edit: Forget it i just had to get the edge of a screwdriver and push it in. Had me worried for a minute.

Does anyone have a link or info on the dummy proof DIY on how to Root the joying unit? I want to install some of these enhancements so need to root the device and have never done it so was looking to see if anyone has a link or good write up for the slow like me. Appreciate it.

Within the zip there is a file with instructions - HOWTO.txt
How-To install:
1. You need a Windows PC that is connected to the same WiFi network as your HU.
2. Unzip the attached file somewhere to your disk.
3. Run CMD.exe as Administrator
4. Change directory to the folder that you unzipped.
5. Run the install.bat script with an IP address of your HU as a parameter:
C:\Users\<username>\Downloads\Joying_JY-UL135N2_SuperSU> install.bat 192.168.123.137
6. Wait until script finishes and reboot your Head Unit.
7. DONE!
You should now have the SuperSU application working.

can anyone help me identify this phone?

Hi @ all, so a friend of mine purchased this weird Phone which came in a very neutral packaging, no brand written on it just a sticker with the model name : Carbon (64 GB + 4 Gb), the S/N and the IMEI.
The Phone itself looks quite standard, its running Android 9 but it doesnt have a Playstore and on the left hand side of the Phone it has a physical switch in which you can use 3 modes,
1 . Normal mode ( all smartphone functions are enabled),
2. Privacy mode ( Camera and Mic are physically disconnected),
3. full privacy mode ( same as mode 2 but the connectivity is disabled)
the device name is by default Tapion.
Buid number: C0.03.19
I cant access the developer options by pressing build number 7 times, nothing happens
I tried to get it into the bootloader mode and recovery mode with no success.
maybe someone here could help me

Can you post more info from your About phone settings?
Install the most detailed hardware info/identification app that you can find. The Aida64 app would be sufficient.
It should give you all the hardware/software specs for your device in several different categories. Take screenshots of the information shown in the various device info pages/tabs so we can all see the information those screenshots display.

Weird Galaxy S9 Glitching

Hello folks. Today I bought a second hand Galaxy S9 (G960F) phone after I totally smashed my old one.
At first, when I ran the service test code (*#0*#) all sensors/the screen/inputs/outputs seemed to work fine. However, after a short time of leaving the place where I met the buyer, I discovered that the phone started restarting randomly.
The first impression, based on experience was that the device is water damaged. I looked at all corners and there is no sign of cracks or splits in the glass. Moreover, I examined the water damage indicator near the sim tray (galaxy s9's have one of those). The indicator was dry white.
I excluded the water damage from thinking temporarily.
So here comes the dilema: Could those glitches be from software? Either firmware or ROM? I tried updating the firmware and the samsung fails to download the latest firmware. The last firmware update is from August 2020.
I have the following information:
- One U.I 2.1
- Android 10
- Baseband version: G960FXXSBETG8
- Kernel version: 4.9.118-18847185 # 1 Mon Aug KST 2020
- Build number QP1A.190711.020.G960FXXSBETH1
- Knox 3.4.1 API level 30 TIMA 4.0.0
- Service provider SW ver.: SAOMC_SM-G960F_CKH_DRE_QQ_0009 / 2b282a7f23017ece (DRE/DRE/DRE)
Lastly,
- Android securit patch level - 1 August 2020
The phone seems to function well. It doesn't seem to be locked on the network which bloats the ROM (3 (Three/Drei) Germany/Austria?)
However, sometimes it just restarts with a open padlock showing on the screen.
I can make this work, I know it and I have the following options:
- If you guys can help me, I could debug the curent software/firmware and get it to shore
- Find out how to install official firmware/rom that is not spoiled (Note: I need all security features and no ROOT. I need to use bank applications etc)
- If these fail, tear the back plate open and change the mother board with my old phone's.
What do you think? Can I achieve something here?
Later edit:
I tried doing a recovery mode factory reset after a cache wipe. When I booted up again I was warned that "A unauthorized factory reset attempt was made".
On the other hand I ran a geekbench and I obtained normal scores without having the phone restarting on load so I think the assumption that the hardware works fine and the phone is still sealed shut is right (?).
Anyone with experience in this - flashing stock firmware?
