[Samsung Galaxy S Duos] mikearzillo:
I have a Samsung Galaxy S Duos GT-S7562 which stopped working with no warning a few months ago. The device has stock Samsung firmware and has never been rooted.

On power-up the device hangs on the Samsung logo.

When a charger is attached the battery charge animation is frozen.

Both stock recovery and download mode are working.

Attempted a factory reset and clear cache through recovery mode. Both showed as successful. Still hangs at Samsung logo.

Attempted to flash official Samsung stock firmware through Odin3. Flash succeeds with no error but restart still hangs at Samsung logo.

Attempted to flash TWRP recovery through Odin3. Flash succeeds with no error but recovery mode still comes up as stock rather than custom.

Why would Odin3 report a successful TWRP recovery flash but the device still boots the stock recovery? I have another identical S7562 that I successfully flashed the same TWRP recovery and Samsung stock firmware using the same setup, Odin3, PC and USB cable. Both are unlocked devices. Disabling auto-restart in Odin3 and attempting to boot straight to recovery after flashing doesn't help.

I suspect that a JTAG recovery may be my only option but from what I've read it should only be attempted if stock recovery and download mode are *not* working. In my case both appear to be working. Would a JTAG recovery help in this case?

Could there be some sort of NAND memory failure that does not result in any error messages during an Odin3 flash?

Thank you for any help!

I guess JTAG is the only way. Sorry.

How can I edit some xml files? I want to try the Gpu 1gz but my system fails to save the file once I open it.

I am rooted by the way
[Huawei Mate 9 Questions & Answers] vijer:
I don't think anyone really understands your post, so you haven't received any responses. XML files are just text files so any editor should work. You would need to be sure that you have read / write access to the file.
[Huawei Mate 9 Questions & Answers] atrix_noob:
Ok, to make it more clear. I am trying to edit a XML file ( Yes Text file ) onthe Product/ETC folder.

The thing is once I open the file with any text editor, or even root browser and try to save the changes I made it gives an error saving file. Tge same thing goes to the Build.prob

If I edit something on it and try and save the changes they won't stick. All the access are correct, read and write permissions are set. Don't know why I can't save the files.
[Huawei Mate 9 Questions & Answers] Icetea:
try to edit it on your sd card!

1.) copy xml file to sd

2.) edit and save to sd card

3.) rename original file to . bak

4.) copy xml file from sd card to target folder

5.) compare right permission management flag!!! (rw-r-r /644!)

6.) reboot

(use totalcommander app or similar for it!)

btw: if this doesn’t work for you, you can try the "fastboot" mode (adb shell and connected phone to your pc for it! - push/pull)

this should work going this way:

* you need usb drivers and mini adb to be installed.

* you have to connect phone to pc (debugging must be allowed!)

* check connection with > adb devices in fastboot mode

* if connected, you should be able to copy xml file to pc -> adb pull <source-path>/xxx.xml <target-path>

* then edit and safe xml to pc folder

* then copy file to phone -> adb push <source-path>/xxx.xml <target-path>

maybe you have to remount target folder r/w with:

adb shell

su

mount -o remount,rw /targetfolder

at first to be able to copy.

* set file permission with -> adb shell su -c "chmod -R 644 /target folder/xxx.xml"

BTW: following this description at your own risk!!! Maybe it doesn’t work!!

I have no own experiences with Mate 9!!

[Samsung Galaxy S8 Accessories] r8dooo:
How do you connect phone to lapdock to enable dex? I appreciate need to root but it doesn't have a HDMI port are you connecting through USB C as some people are saying struggling to get USB C monitors working

Thanks
[Samsung Galaxy S8 Accessories] StardustGeass:
It is using a USB-C connection. I won't say the connection is flawless, as sometimes it doesn't connect to the keyboard and mouse or having a non-HD output (simply re-plugging the phone does the work), but I won't say it is a struggle to make it work. It works like 90% of the time and when it is connected, we can use it without a problem (except the sound problem, see my explanation above).

Also, it have a micro Hdmi port. But, as far as I try, it doesn't work for mirroring the dex for another screen.
[Samsung Galaxy S8 Accessories] Xombie11:
Thanks for this review.

I got the LapDock as well but sadly haven't been able to use it since Oreo Beta 3. Fingers crossed that one day Samsung will re-enable support for third party docks. Sigh...

I also found the trackpad experience particularly poor. The BT mouse is a good solution. Also I would sometimes have issues where if the USB-c cable were moved or nudged, DeX would reboot which is annoying as it takes quite a few seconds.

Also I found that the LapDock battery drains very fast when it is not in use. I would charge it to full, disconnect it from power and store it away. After only a week it would no longer have a charge.

I wonder if the new firmware makes a difference... I've been meaning to visit a Microsoft store to borrow an Elite x3 to use to update it. Do they even sell those anymore, though?
[Samsung Galaxy S8 Accessories] StardustGeass:
Agree with all of your points..

Except, for the nudging cable problem.. I often changes my phone place but never once I encounter the DeX got rebooted because of missing connection..

Somehow, the battery drains very fast. I think it is caused by the lap dock only enters hibernate mode instead of totally turning off..

I also wonder about the firmware difference... I read on the news that the firmware "fixes" trackpad (enables it to have a right click instead of tapping it with two fingers), and something regarding battery indicator...
[Samsung Galaxy S8 Accessories] Meleor:
Well I have a friend who tested the Mirabook at CES and he said the experience was pretty smooth and well designed.

He tried with a Samsunsg S8 and DeX launched quickly while the mb charged the phone.
[Samsung Galaxy S8 Accessories] StardustGeass:
That's nice! Excited to hearing about it when it finally released!!

That means, at some time, if my hp lap dock went down and I want to change phone, I don't need to root my phone anymore :D
[Samsung Galaxy S8 Accessories] erclalle:
Good to see such a thread! I sport the elite Dock since december as well, and I may have posted an issue elsewhere, which I'll repeat here as well, the 45W chargers only work if they deliver 2.25A, so some 2A don't charge it for some reason. Also, I don't know if some usb-c cables are more potent than others, but while the provided usb-c cable works (it's quite short though) another one I took from a wall usb-c adapter doesn't even though it allows simple data transfer.

It's a shame that we can't update firmware, even from a Windows laptop. By the way, it totally doubles as an external monitor for a laptop either with miracast or by plugging it with the same usb-c.

It's also annoying that I haven't found a reliable way to power it off and not put it in idle mode, so sometimes it drains overnight :/

I'm putting it aside for now, and I'll wait for the 'Linux on DeX' thzt samsung promised us, that will be a game changer!
[Samsung Galaxy S8 Accessories] StardustGeass:
Yeah.. I once panicked since I lost the charger.. Buying some 45W USB C charger doesn't help, and thankfully I finally found it back...

I think the way to turn it off is by pusing the power button for several seconds? I usually did that and helped the battery reserves...
[Samsung Galaxy S8 Accessories] erclalle:
I actually did not want to use the stock charger since it uses USA power plugs (and I couldn't find the european end bit, even though it's a modular bit) so I used the Inotech 45W charger found on amazon, and it works!
[Samsung Galaxy S8 Accessories] StardustGeass:
Wow, thanks for the input!

Could you share me the link? Thanks :)
[Samsung Galaxy S8 Accessories] erclalle:
sorry mistyped, 45W Inateck*. For some reason it disappeared from the French Amazon where I bought it, this is the usa amazon link, http://a.co/9E42eSW , but if you look for it in your country's store, you'll find different end plug parts
[Samsung Galaxy S8 Accessories] Xamadeu:
Hi, here are my experiences

i have a g955fd and hp lapdock.

Was Nougat aql5.

Now is CRB7.

No custom rom till now.

With aql5 got no wireless connection.

With crb7 get no cable connection.

with aql5 no display but working keyboard

with crb7 working display (no dex) but keyboard error: all keys are doubled

Someone else with these problems?

Are these problems solved somewhere?
[Samsung Galaxy S8 Accessories] StardustGeass:
Sadly no... Main problem is, Samsung check whether the device is dex compatible or not.. Only way to bypass it is by flashing custom kernel...
[Samsung Galaxy S8 Accessories] Xamadeu:
Now, got a cable connection also with new firmware, but not reliable. A question of order of connecting and powering?

But still no display with cable.

Anybody else with same problems?

---------- Post added at 10:50 AM ---------- Previous post was at 10:48 AM ----------

Well, i aim to flash custom for dex, but that only brings dektop, but will it bring bugfix for double keys when wireless or dark display when cable connection respectively?

---------- Post added at 10:56 AM ---------- Previous post was at 10:50 AM ----------

And mouse pad did not work ever.

---------- Post added at 10:57 AM ---------- Previous post was at 10:56 AM ----------

The windows app for firmware updates of lapdock should work with win 10. I have none. Did somebody try?

---------- Post added at 11:00 AM ---------- Previous post was at 10:57 AM ----------

Does somebody know how to check firmware version without windows app? I found some pictures/vids with light grey screen when connecting and other with dark screen. Which is newer? Mine is light grey.

---------- Post added at 11:02 AM ---------- Previous post was at 11:00 AM ----------

Does somebody know, which firmware versions exist and what the differences are? Found no web-infos till now.
[Samsung Galaxy S8 Accessories] StardustGeass:
1. For cable connection :

To be honest I don't have problem with cable connection (using batrom on nougat and renovate on Oreo). Well, sometimes it doesn't detect the keyboard / mouse or displays a non-HD screen. But, a simple reconnect fixes the problem.

2. Regarding flashing custom ROM and bug fix :

So far, I don't think so..

3. For mouse pad:

Mouse pad only works on Oreo firmware, and when there is no mouse input device.. It usually doesn't show up on hp elite, since hp elite already have TouchPad.

4. Regarding windows update :

AFAIK, you can only upgrade it using hp elite x3 phone. Currently no way to upgrade it using android..

Thanks!

and some say it works on lumia also.

---------- Post added at 11:21 AM ---------- Previous post was at 11:18 AM ----------

my light grey screen says

lap dock 083af 8.0.11.0!? Is it a firmware version? What does yours say?

---------- Post added at 11:37 AM ---------- Previous post was at 11:21 AM ----------

The cable bug display dark: any settings of s8+ wrong? display resolution? (already tried all three variants)
[Samsung Galaxy S8 Accessories] StardustGeass:
1. Yes, since lumia is a windows phone... I don't have one though, so can't say a thing about it...

2. What Grey screen you mean?

3. What do you mean by display dark? No output at all?
[Samsung Galaxy S8 Accessories] Xamadeu:
Yes, no output at all, attached is my grey screen.

and the dark display when cable is connected, picture taken by s8+, only thing you see is reflection of the screen.
[Samsung Galaxy S8 Accessories] Xamadeu:
This guy has no grey connection screen like me! But a dark connection screen.

---------- Post added at 12:20 PM ---------- Previous post was at 12:05 PM ----------

I can reproduce the cable problem: it seems to be the cable itself.

if i turn the plug the connection works or not.

if i swap both ends of the cable, the situation keeps the same.
[Samsung Galaxy S8 Accessories] StardustGeass:
Hmm... I can only think one possible answer right now, which is a faulty hardware / software on your hp elite.. Especially since I am not able to reproduce your problem..

Note :

I also not using the official CRB7, but since the renovate ice custom ROM I use is CRB7 based, I think our output should be the same...
[Samsung Galaxy S8 Accessories] webbanane:
Yes, i already contacted the seller.
[Samsung Galaxy S8 Accessories] Xamadeu:
tried another cable, no success.

Some report bugs on the firmware.

Can you tell, what numbers (perhaps that are firmware versions) are displayed on your start screen?

i tried to install the app for firmware updates (hp lap dock wireless settings) on pc and windows phone, but it did not install, although it says for win 10 and win phone. seems as if it only works on x3, but some report, that it also works on lumia.

in the discussion below youtube video the video author solved it by switching the original cable usb c 3 to usb c 2.

I could NOT solve it with cable usb 2.0. Same problem as before.
[Samsung Galaxy S8 Accessories] StardustGeass:
Mine is still working for now, currently have no idea what caused yours to not working...

Still a black view?
[Samsung Galaxy S8 Accessories] Xamadeu:
Still black view. I returned it. Planning to order another one.

Can you answer my question?

When you turn on the lap dock and it waits for connection, numbers are displayed on a grey view (look at my screen **** above). Can you tell me your numbers?
[Samsung Galaxy S8 Accessories] StardustGeass:
On mine, the numbers are:

HP Lap Dock 002E97

8.0.11.0
[Samsung Galaxy S8 Accessories] Xamadeu:
Thanks, so it is the same as mine.

Do you know your order item number?

Mine was Y1M47EA (german keyboard).
[Samsung Galaxy S8 Accessories] StardustGeass:
What is order item number? Is it printed on the lap dock?
[Samsung Galaxy S8 Accessories] Xamadeu:
Something like the model type. The type number of the article to order. Not the series number.

For hp lap dock maybe Y1M47EA, Y1M48EA, Y1M49EA, Y1M50EA, ...? This may be in europe and may differ in us etc.

Previously i ordered Y1M47EA, now i ordered Y1M48EA. Difference is only the package. Perhaps they have other firmware versions, too?
[Samsung Galaxy S8 Accessories] Xamadeu:
part number
[Samsung Galaxy S8 Accessories] StardustGeass:
Hmm.. I bought the refurbished model on Amazon, so don't really remember / know what part it is...
[Samsung Galaxy S8 Accessories] Xamadeu:
Hello, I got a new one. Exactly the same problems. Screen keeps black.

I found information about the updates for the lap dock firmware: one update changes the timeout of keyboard backlight. Before it keeps on, afterwards it has a timeout of about 15 seconds. Mine had no timeout, hence has an old firmware and i wanted to update. Update is ONLY possible with HP elite x3 mobile. Now, I bought a used hp elite x3 mobile. I used it with the lap dock and the lap dock works flawlessly and full screen.

It is weird. There are two apps for the lap dock. hp device hub and wireless settings. Both update the lap dock. Every app updates one part. wireless settings updates the wireless part und and hp device hub updates the cable part.

I updated the lap dock. The screen no longer shows the number 8.0.11.0. But the update app told that is has been updated to 8.0.12.0

Afterwards the bug with S8 and wireless keeps still the same: keys of the keyboard are still doubled. The wireless screen has a letterbox as before, but it can be adjusted to full screen on the s8 by changing the aspect ratio.

The bug with S8 and cable has changed: Dex connects! But it has weird problems. It loops three times until it is "synced" with the screen. Afterwards it has a letterbox, too, and there is no simple solution. It gives an error message:

Your Monitor/TV can not show Samsung Dex. Your Device must have HD+, FHD or WQHD Resolution, to show Samsung Dex flawlessly.

The screen has a weird resolution and everything is unreadable.

One App shows the resolution of my dex: it says width: 411, Height 731. Of course that is not enough and bad.

I tried several apps, that change the resolution of the mobile screen. I could adjust the aspect ratio to cover the whole screen, but everything keeps unreadable.

It seems that the lap dock always resizes the bad resolution to letterbox or pillarbox.

Can't get the lap dock to work correctly.

Dex has an option to change the resolution natively but the option for FHD is greyed out. :( There is only the option for automatic detection and 1600x900. But nothing helps. :(
[Samsung Galaxy S8 Accessories] Xamadeu:
Tested Dex with a FHD TV. Works! No Sync problems.

But the screen info apps show the weird resolution, too, but that is not true, the real resolution ist good/fhd.
[Samsung Galaxy S8 Accessories] StardustGeass:
Hmm... It is strange as mine still works right now...

FHD and no black screen..

What ROM are you using? What kernel?

The problem I have right now (using renovate 10.1 with noxx beta kernel), is that my hp lap dock doesn't have audio output.

When I use batman ROM (nougat version), the audio outputs but somehow not clear (very different experience when using it wireless-ly)..
[Samsung Galaxy S8 Accessories] Xamadeu:
tried reno 10.1 and 9.3 with r7 nox

---------- Post added at 08:54 PM ---------- Previous post was at 08:49 PM ----------

once wireless worked without double keys but only once
[Samsung Galaxy S8 Accessories] Xamadeu:
This is a screenshot. It is crisp and clear. But the screen is not. It is visible: a good resolution. But the info app says something different. Weird.
[Samsung Galaxy S8 Accessories] Xamadeu:
Other windows mobile devices work with my lap dock, must be rom or kernel or s8+ hardware. I suppose rom. Another promising rom would be oxi, but it is not available for s8+, yet. Needs lineage os first.

is your noxx beta newer or older than r7?

Can you give me your beta kernel?
[Samsung Galaxy S8 Accessories] StardustGeass:
It's a noxx kernel v 66...

I am not sure whether I am permitted to share the file or not... I also not know how to share files sent on a telegram group... Sorry..

To use dex mode, you need a Samsung (S8/note 8/S9) based mode, so lineage-based OS is a no no...
[Samsung Galaxy S8 Accessories] Xamadeu:
noxx closed the telegram group, seems as if it is not productive for him

i dont think he refuses forwarding the kernel

do you know, is v66 older than r7 or newer?

oxi is not dex but an alternative running on lineage os
[Samsung Galaxy S8 Accessories] wozz9192:
Hmm had a lapdock with shocking battery so I got another under warranty. Now with the new one I get a similar issue.. screen resolution is extremely low, so the picture appears very blocky etc.. I think it's a problem with the HDMI handshake possibly? Also half the time in plug in the phone on the new lapdock I just get no display. If i switch on the lapdock without an phone connected it shows 0062E1. Considering buying a used x3 mobile to see if I can update firmware
[Samsung Galaxy S8 Accessories] Xamadeu:
The problem seems to be independent of Dex mode, also with only mirroring. Syncing several times till connection works, sometimes not. Tried several different cables with the same result.

Tried new nox kernel r8, same result.

Native phone resolution is not matching to display for mirroring. Changed phone rsolution with app and root to fhd, but get no connection.

62E1 seems a kind of serial number. It changed with devuce change.

If no additional number appears like 0.8.11.0, it seems as is it already has an update. The additional number disappeared after update. Another symptom of already being updated is: keyboard light does not keep always on, only for 15 seconds.

I bought a used x3 and sold it again for update, successfully. But even connection with x3 is instable! But resolution is fine.

Be aware, there are two updates! Wire and wireless! And two! apps! HP Device Hub and HP Wireless Settings! Crazy idea of hp.
[Samsung Galaxy S8 Accessories] wozz9192:
Mine does still show 8.0.11.0, but after reading your post seems the update isn't worth bothering with. Annoyingly enough, if I connect it to my lg v20 it connects straight away perfectly at the right resolution every time.. I'll test with my s7 later out of curiosity
[Samsung Galaxy S8 Accessories] Xamadeu:
yes, am interested in s7
[Samsung Galaxy S8 Accessories] Xamadeu:
Also interesting:

if some s8 (and several other devices ms and android, hp x3, lumia 950 xl) work with lap dock out of the box and some not, if those s8 that dont, work with other full hd screens at all.

---------- Post added at 09:24 AM ---------- Previous post was at 09:19 AM ----------

Oxi by auxens is another custom rom based on lineage os, but not available for s8 yet. It supports a desktop mode like dex. A version for s7 also exists. The version s7 has two variants, one special for hp lap dock and one common for the remaining. The special has a special miracast stack! Why? Because hp lap dock has a miracast problem with doubled keyboard keys? is there an alternative miracast stack for s8? perhaps lapdock then works correctly wireless?
[Samsung Galaxy S8 Accessories] Xamadeu:
Experiences with s7?

Other experiences with s9?
[Samsung Galaxy S8 Accessories] StardustGeass:
I think S7 won't work because as far as I know, hardware-wise, S7 doesn't support video (and audio?) output through micro USB.. So it will only works with the screen mirroring options, but not full dex compability.
[Samsung Galaxy S8 Accessories] Xamadeu:
But it has miracast. Perhaps it works flawless without doubled keyboard keys?

---------- Post added at 11:04 AM ---------- Previous post was at 11:02 AM ----------

s7 has no dex?

Another alternative for dex is the app sentio desktop.
[Samsung Galaxy S8 Accessories] StardustGeass:
Haven't tried other phone on my lap dock so can't say for sure about the double keyboard keys..

Also for S7, I think sentio desktop won't work as well, since hardware-wise, S7 USB port doesn't support display port, which is used for transmitting audio and video through USB port.
[Samsung Galaxy S8 Accessories] wozz9192:
just realised after I posted that the s7 is micro USB not usb c so no chance of displaylink over usb c
[Samsung Galaxy S8 Accessories] wozz9192:
Hmm just tried lapdock with a lumia xl950. Everything works perfect in continuum, though can't update firmware with that phone. Trying to find someone with an elite x3 so I can test update firmware.. just not sure what else could be different from the last lapdock I had that actually worked with the s8 (except for the battery problem). Damn it looks good when it's working, just really sucks I can't get it going with my s8..
[Samsung Galaxy S8 Accessories] Xamadeu:
Do you now the different part numbers that work and that not work?
