[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
Hey all! I have made the switch to a Nexus 6P about a year ago, so I am quite rusty with the S5 and how to do things with it. I recently sold an S5 on swappa, and I am attempting to help that user get it back to stock. I would have done this before selling, but we thought the process would have been more simple.

To quote the user I am assisting at the moment "... I crossed into canada a few days ago, phone worked good with international plan. cross back to US and keep getting weird "not registered on network" messages and have 0 connectivity to my Verizon phone network. Tried new sim card, verizon store says the issue is because it is rooted etc (doubt they know what they are talking about)....But figured i'd do a clean install etc and see what happens. Followed instructions for Odin. From what i read it sounds like I need the OA 8 Lollipop retail tar..phone model number is SM-G900V. Keep getting "NAND Write Start!! FAIL! (Auth)" in Odin. Tried multiple USB cables and other random tips I found online. Any advice? Am I using the wrong stock tar?"

What can I/we do to resolve this issue? I have searched xda, but I am totally lost with the S5 to be honest. Things have changed so much since I used the phone that I have no idea where to start. It was on Alliance ROM before I shipped it. It has the Toshiba eMMC (or whichever doesn't have bootloader unlock).

Again, thanks in advance guys!
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
Some more info about the phone, I'm the buyer.

Still running Alliance. I do have an IMEI # (some sites say that could be an issue).

Model/Phone name is Samsung Galaxy S5 SM-G900V

Baseband Version is G900VVRU2BOK3

Kernel Version: 3.4.0 dpi@SWDD6518 #1

Tue Nov 17 20:06:51 KST 2015

Build number: AllianceROM_VZW_V10_G900V_XXU1BOH4

Knox version 2.3

Exact message I get is "out of service area" when i make a call. then a "mobile network not available" message will pop up after.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
Silly question, but have you tried pulling the battery, and Sim, let it sit for a sec, then power on to see if you have service? Might just need to reset the prl. Never been to Canada with the phone so idk what's going on ha.

Could also check the data settings to make sure it's set to CDMA+LTE instead of global or whatever other options it has. You haven't flashed a new radio file, have you? [MENTION=8190451]miketon907[/MENTION]
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
Pulled battery out and sim. No service fix. If I turn phone on with sim card out, it will say "no sim card". back sim card back in, no net work connection....It is set to CDMA+LTE. No, I have not flashed a radio file.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
Ok, just trying to rule things out.

You activated the SIM in the US and used it before going to Canada, right?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
Yep. so Sim card A which I got after buying the phone was working good. I went to Canada and used same sim card on international plan, went back to US and suddenly phone loses mobile connection and has no service as soon as I cross US border. went to Verizon for sim card B, sim card B does not work either.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
You could try just doing a factory reset on recovery if you haven't already. Instead of starting from stock. Just wipe the data partition. If you wipe the system partition it won't have anything to boot into
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
oh. Well i'll try that later tonight. Report back around 11pm est. thanks!
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
ok did that. (wipedata/factory reset->wipe cache partition). still have alliance-safestrap etc on the phone. sim card still giving weird messages.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
Still the same messages?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
yes, same messages.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] tr4nqui1i7y:
Try flashing one of the modems on this page. It should reset the radio to have service again. I'd do it without the sim card in. Boot once, you obviously won't have service since there isn't a sim. Then turn off the device, insert the SIM and reboot.

I am looking into the write fail now just in case you can't even flash a modem file.

Also, you downloaded the samsung drivers, correct?

EDIT: I found an old thread that might help you troubleshoot odin - http://forums.androidcentral.com/sa...hacks/391849-galaxy-s5-odin-failing-root.html

EDIT 2: You might just have to switch to a different tar file. This user states that they used the same stock version as the one they were currently on. I'd give that a shot first. Then check to make sure "block reactivation" in security settings isn't checked. The exact directions that should get you going are from a user on that page, as follows;

"chainfire xda quote op-Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)

- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one

- (USB) Disconnect your phone from your computer

- Start Odin3-vX.X.exe

- Click the PDA button, and select CF-Auto-Root-....tar.md5

- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)

- (USB) Connect the phone to your computer

- Make sure Repartition is NOT checked

- Click the Start button

- Wait for Android to boot

- Done (if it took you more than 30 seconds, you need practise!)

NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.

New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!" - Dale Borrelli

Final note. Try the tar for the android version you are currently on first, then go up to the version you'd like to be on.

Edit: [MENTION=8190451]miketon907[/MENTION] any luck yet?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] miketon907:
yes, thanks a lot. flashing the modem worked. have service now again.

Do you have the problem I have where music sounds bad coming from most apps for music accept for CD and radio?

I posted in a separate thread how there is some weird filter applied to music where it severely messes with volume during listening to music... but it doesn't always apply to all apps playing music for some reason.\

Bad: soundclound,stock music player, all music players I have tried from play store, music streamed via Bluetooth through my phone

good: cd, radio, Netflix.

do you have any insight on that?
[Android Head-Units] kthejoker20:
It's not a filter.

There could be a couple of issues.

First, our cars have a digital audio processor.

Do you have the radio hooked up through the factory speaker wires? If so this DAP is module wired in that you can't get to. I had to run new speaker wire around it.

You could try disabling the active noise cancelling mic.

Otherwise, if you have that taken care of, the problem is with the software audio routing.

Did you install kingroot? If so,its a known issue to cause audio problems, it interferes with the stock permissions and cause the radio to go into mono and a bunch of other crazy stuff.

But I would put my money in the first issue.

do not install kingroot you will break the system.

You can't uninstall it either as the changes it makes will permeantly break sound quality
[Android Head-Units] darkside212:
I just picked up this unit for my 2014 ford focus.

have you figured out the password for the developer options? I've tried a bunch to no avail.

also is there a way to get to the factory settings? it doesn't appear in the settings menu.

thanks for all the help!
[Android Head-Units] AAAAAAA7:
3368 Was the password for me

---------- Post added at 01:08 PM ---------- Previous post was at 12:48 PM ----------

I don't believe we have the same car? Mine is a 2010 Toyota venza. It doesn't make sense to me that a DAP that's not part of the android radio would only affect sounds from some apps and not others?

I have not installed kingroot.

My audio problems isn't like what you describe, it's like if it messes with volume whenever a new louder sound starts playing.

[Android Head-Units] kthejoker20:
This radio is ONLY for Ford fusion. There are many varients if this radio. It's not the same, even though it may say so. Sorry we can't help.
[Android Head-Units] darkside212:
I was able to install car launcher, from there I was able access more apps. I was able to bypass the "locked down" settings, and verify it is a quad core a9 w/1g ram. The item was sold as 2g ram so it will be returned.....
[Android Head-Units] kthejoker20:
It's easy to bypass, install Nova launcher and set a default.

Then open as possible drawer, select dev tool, then dev setting.

That will bring you to the dev menu.

DO not install kingroot.

Try pass 162
[Android Head-Units] kthejoker20:
This is a totally different radio then what is being discussed here.

Ours us is a a7
[Android Head-Units] darkside212:
yeah it look identical (other than the housing) as far as the skin etc.

I was hoping it was the same, but apparently these units can be very different.

I'm not sure if it helps, but there was an app called "hidden system" that allowed me to see more about the unit.
[Android Head-Units] kthejoker20:
We don't have that one in our system. I've thoroughly picked through the system already.

I guess what exactly are you looking to do? You have to be very careful with these, they are not normal flash able Androids, they rely on the mcu to operate.

So simply getting root could break a lot of things and cause audio problems and stuff
[Android Head-Units] darkside212:
I'm good.

they had the system settings really locked down but I was able to get around them via car launcher. I just posted in case anyone else need that info.

they didn't have the "factory settings" available which was annoying as I wanted to turn off some of the settings.

thanks for the help!
[Android Head-Units] kthejoker20:
Most common cause for bad sound is the radio is set to "High impedance mode". You need to access your system menu. Usually, by clicking the yellow gear, then select system. Then hold your finger on the information box on the right and a secret menu will appear. Enter code 7890 and then hit ok. Go to the setting that has 2 boxes, one of them should list your vehicle. If you see whatever vehicle is listed there with an "H" next to it, that is definitely your problem. Select it, and change it to "L" or if your vehicle is not listed, select the nearest similar vehicle with an "L".

Hehe I'm glad there are crazy people like Patrick & I to work on this HU! I already modified a lot of their Engrish and Patrick helped me locate the bugs. I fixed them and he tried really hard with me to get the HU almost perfectly working. I'm still actively working it as we speak right now. I was able to port AA successfully (Somewhat lol). I modified their own launcher and some minor stuff on BT,Radio, AC, I'm still working on a different UI for the Radio and AC controller. I'm about to purchase another HU for my Focus. Right now, I only have it in my Stang. Let me know if you need some help to modify stuff around. I made some CustomROM for members to help them getting the fixes without having to root it. I also built a script to get root without KingRoot. So far it's been stable using SuperSU... (Knock on wood:D) I'm actually working on a Custom Kernel to OC the CPU and mod the Hardware to add like a little fan to cool it down. So far, There are 2 different release of the HU for the Mustang. I was able to get both units working the same way by making 2 custom ROM.:good:

PS: We got somewhat the SWC Voice Activation working. I'm looking at tasker to make it work somehow with the Google Assistant.

Do you guys have a github? I looked around and didn't see any source code on the links you provided. You mention your working on the kernel, where did you get the source and can you share it?

If you guys are working on the event app, we should put it into github with gradle. Then we can modify and update as needed.

Hi kthejoker20

can you please help me with an advice, to recover my head unit for lexus rx330.

I purchased it from aliexpress and then wanted to update android to get rid of some bugs

(screen brightness not controllable, and radio sensitivity low)

I just pushed the button "Android Update from USB" then it required password, I entered 0000,

it accepted and rebooted, after reboot it shows the error screen and stops loading further.

and so happens every time I reboot it or power up.

I really have no idea how to recover it.

I asked seller to help, they gave me the update image, I put that image in sdcard/usb stick and try to power up with it,

but the device still shows the error message and stops on it.

Please give me some advice solution.

P.S. I don't know know how to place screenshot images here, so I uploaded them in Imgur dot com, and here are codes after slash

for each photo

Delete.
[Android Head-Units] kthejoker20:
Unfortunately, I am not familiar with your specific varient.

You can check your control box and see if there is a micro USB port or an SD card slot. Then it could be recoverable. But you have a totally different system from this thread.

If you have those slots, you can fastboot into uboot and then FIRST pull a back up, then unpack your image and fastboot flash each partiotion,. Except for the kernel and boot. Do not flash those.

That's your only option, and I cannot provide specific instructions as each unit is different.

Your tricky part is going to be how to access the uboot without any hard keys.

Your best chance is if you dieciver anvsd card slot on the device. You may be able to boot off that to reimage the unit. use win32diskinage and burn that image you received to an SD card and then put sd card into unit, cross fingers.

Otherwise, you may get lucky just keep hitting ok on your error message and it may eventually boot into android. If so, immediately insert your USB image and let it update.

Nothing else we can do for you. May be easier to send it back. These units are NOT forgiving and can't be tinkered with by.non devs, being able to flash a zip does not make you a dev

Installed v2.0 without issue, but still no wifi.

The WiFi Fix app says that it resolved the problem, but it persists nonetheless.

I tried going into the System Set and changing the bc6 to another setting as recommended, but again, no luck.

The three options I see are different than the three you mention. Mine are: bc5, bc8, and bc6 (default).

Changing them had no immediate effect on wifi, and after rebooting, the setting reverts to default.

I am trying to Kingroot, but without an internet connection it will not proceed.

Tethering also does not work, as a USB connection is not detected by my phone.

Any ideas?
[Android Head-Units] kthejoker20:
When you change the bc6 .....etc.... You have to reboot on each change.

So when you change for example bc6 to bc8, you need to reboot the system. Then check for wifi. Then change again if it doesn't work

Basically this let's you change the wifi driver, but it won't take effect until reboot
[Android Head-Units] soul_train_:
I am rebooting, but as I mentioned, the setting does not hold after doing so, and reverts back to default (bc6).
[Android Head-Units] kthejoker20:
I would leave it then. Have you tried the factory reset? And wipe cache?
[Android Head-Units] kthejoker20:
One more thing, I know it's the obvious, but

........

Are you sure you have it enabled?

Hit yellow gear. Then more settings on top.

The on the left side, there is a switch looking button. On the wifi menu option. Make sure that's on.

You never know.....
[Android Head-Units] soul_train_:
Factory reset, yes.

Wipe cache, no. Will try.

---------- Post added at 05:45 PM ---------- Previous post was at 05:44 PM ----------

Yep. The switch goes to the right and it says "Turning on wifi". Then it fails and switch goes back to the off position.
[Android Head-Units] kthejoker20:
I'm wondering if your customer.xml is reverting the driver back.
[Android Head-Units] soul_train_:
I dunno.

I used Google' s live translator to read those optipns, and the bc6 thing is related specifically to Bluetooth, not wifi.

For the record, Bluetooth does not work either.

I looked at the Wi-Fi settings, and noticed that theres no mac address listed.

It must not even see the Wi-Fi radio.
[Android Head-Units] kthejoker20:
It's ok. Bluetooth and wifi drivers are the same on this unit. One won't work if the other doesn't.

I'm positive the driver isn't loading. What's causing it is baffling me. But I'm thinking customer xml.

This radio, the mcu controls the wifi and Bluetooth. Pia

Did you try the otg client mode to get usb tether?

Otherwise, a last option that will work, but a little tediuous, is to get a USB adapter wifi.

Like $10,. But I have to get you some code to program in to get it working. but save that for absolute last
[Android Head-Units] soul_train_:
Could not get tethering going either.

USB-wifi seems reasonable, but will have to wait until my next home-swing. (back on the road tomorrow morning)
[Android Head-Units] kthejoker20:
You do a lot of traveling. Must have an awesome job.
[Android Head-Units] kthejoker20:
Might be worth trying to reach out to the seller and see if they can send you the stock image.

That's how I got ours.
[Android Head-Units] kthejoker20:
As a last easy fix, try PDA net or tether lite from the play store for USB tethering.

You might have to download it from a apk mirror site and install via USB. Install on both phone and radio.
[Android Head-Units] soul_train_:
Will give that a shot.

Thanks kthejoker20

I finally managed to unbrick my device from sd card, formatted with a special tool.

but there is another problem which existed also before updating,

maybe you can give me some advice on that,

the problem is with screen brightness, when I put brightness slider to 0% it gets a maximum brightness,

but when I put it to 100% it dimms a little bit (a very little, hardly noticable),

and so there is no way to have it dimmed during night drive, its pretty annoying in the night, too bright display.

Do you know where to dig? maybe there should be some system files in which there is writen settings for that.

for me it seems like the brightness value is 16 bit, but the slider controls only least significant 8 bits, (also inverted).

thanks

[Android Head-Units] IIABODEII:
Thanks! I have no intention to flash any rooms or anything, I am just wondering if I can find a fix to some problems with the unit. I won't bore you with so much text. I uploaded a video to YT that explains everything.

https://youtu.be/X9TGQextq0Q

I had to mute the videos because my son was making noise

basically:

1- backlight can't be controlled or adjusted (brightness can't be changed)

2- can't turn off screen, the buttons mute instead of turning off the screen.

If i can't find a fix to this, i'll just throw the unit in trash as it's too bright to drive at night. It seriously makes my eyes hurt
[Android Head-Units] bphillips09:
Have you tried disconnecting the screen and firmly re-seating the cables to ensure everything is connected properly?

Also, have you tried contacting the manufacturer or the person who sold it to you?
[Android Head-Units] IIABODEII:
I installed the unit myself, and I'm sure it was installed correctly. The unit worked perfectly, all functions were working (radio, gps, illuminated lights.. Etc)

Now i have the unit in my house and I'm using DC convertor (8amps) so I'm only using two wires needed to make the unit work(yellow, red and black)

From my experience with android, I'm sure there is a way to manipulate how those buttons work.
[Android Head-Units] bphillips09:
By disconnecting, I mean opening the unit itself and removing the cable that attaches the display to the android board. Then firmly (but carefully!) reconnecting it.
[Android Head-Units] kthejoker20:
Force close eventventer.apk

Then try a factory reset

If you feel like throwing it away....send it to me.
