[Xperia Z3 Compact Q&A, Help & Troubleshooting] kjplasma:
I've got a strange one where when connecting a Z3C to the aux input on my Ford Falcon there is a loud crackling noise from the car speakers.

I've tested with other phones like iphones and samsungs and the sound is clean without issues.

Tried connecting a friend's Z3C and the issues occurs same as when I connect.

I have tried different aux cables and played with the settings on the phone and the car but can't seem to resolve this weird one.

Can anyone shed some light on what else I can try please? :confused:
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Dhgr8:
Does the crackling noise stops when you start playing something?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kjplasma:
no it does not and is quite audible throughout, playing fm or aux via any other phone seems to be ok.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
What firmware are you running? It could be possible if you are running MM there is a bug with that or something similar so try downgrading to Lollipop or KitKat
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
Turn the connector back and forth in the socket, probably your contacts are dirty. Did u use phone e.g. under water?

[Xperia Z3 Compact Q&A, Help & Troubleshooting] kjplasma:
I had the issue on lollipop stock and now upgraded to MM stock and the issue still exists.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kjplasma:
I don't think it is the connector as i can hear clear when using headphones or connecting to other speakers via aux. Also the fact that the same issue occurs when i connect another Z3c belonging to a friend of mine

Any other ideas?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
Maybe sxchange the AUX cable...

Still try twisting back and forth, had the sane issue on mine, and somehow it depedet also on what I connected. An amplifier connected via a bad contact is different from a passive headphone.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] kjplasma:
Cleaned the headphone jack and also tried a new aux cable made by belkin and its still noisy as ever. When twisting back and forth the crackling intensifies and if i keep doing it the music on the phone pauses.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
That's correct. if the phone thinks that the headphone is disconnected, then the player goes on pause. I could solve by twsting, but it might be that your hardware has contact issues as well (read that this happens, connector somehow broken)

I also observed mainly on an AUX cable that was a not so good one (connector) but it's now working again, so I guess I had luck.

If cleaning does not help, several cables have issues, then worst case you need to send to repair for replacing or resoldering the Headphone Jack..

Anyone successfully do this? Since having to downgrade the RUU? Thanks
[HTC 10 Questions & Answers] afuller42:
People have and it works when flashing the Verizon radio afterwards, but personally i would just wait for verizon to update. Its always best to be on your carriers firmware instead of mismatched builds.

This will require s-off.
[Android Apps and Games] varxtis:
Im trying to create a widget for Unified Remote that allows me to jump back or forward 5sec in MPC (In Media Player Classic, the shortcut keys are Arrow keys left and right). Unified Remote info shows there should be a remote titled MPC-BE when going into "Change Action > Remote Action" that has such shortcuts. But it's not I figured Id just try to use a shortcut key itself as an action, but there are no keyboard remotes listed either when going into "Change Action > Remote Action"

Does anyone know how can I allocate the computer keyboard keystroke "Right/Left Arrow" to a Unified Remote widget?

Also, does anyone know where the icons for Unified Remote (as in icons used for the widget buttons) are stored/installed? Can I add my own?

and lastly, does anyone know how to backup/save any information relating Unified Remote to copy over to another device?

[Windows Mobile Development and Hacking General] KarhU:
Hello guys,

I would like to ask if there is an app that would benchmark the ROM performance as opposed to the device performance as in the most of bencmarking apps available (SkTools, SPB Benchmark...). These apps can be used to benchmark ROMs too - but they show more about actual drivers performance than real life experience.

I did a search on the Internet but found nothing.

Is there anyone able to code such an app for the xda-devs community?​

I am looking for program that would measure following:

- Boot up speed

- Start menu open speed

- Speed of opening settings menu from the Start menu

- Speed of opening programs menu from the Start menu

- Speed of opening the Windows folder from the Explorer

- Speed of opening a standard built in app (for example emulating green phone button press to open the dialer)

- Speed of changing screen orientation form portrait to landscape and back

- Speed of wake up from stand-by

- catch-all master statistic (derived from all other stats) to make it easier to rank the results for various ROMs/Devices

Any other statistics you may consider important when it comes to the speed of your shiny new cooked ROM. Please advise on what can also measure actual ROM performance.

The app would ideally run these tests several times (10x) and then log the average values into a results file.

I think it would help the ROM cookers to troubleshoot their creations and new users to choose the right ROM for them. In short this new application would test the GUI reactions - no benchmark app currently available does it. It is an important characteristics though, because that is what users come in contact with most often.

Thank you for your contributions!​

Thanks to MaRaHoX for his advice
[Windows Mobile Development and Hacking General] CharlyV:
May we will take a look ...
[Windows Mobile Development and Hacking General] KarhU:
Thanks a lot. I think GUI performance benchmarks are useful even in device to device comparison.
[Windows Mobile Development and Hacking General] mrvanx:
(Rare post by me but...)

Perhaps a single benchmark score would be good to determine the relative difference between the ROM being tested and a controlled test....ie WM6 Vanilla??

so a ROM which scores out in total maybe 3 times better (overall) than the control ROM would score like this:

"XDA-Bench score: 3.00" .............. something like?

the best overall performing ROM would have the highest overall score relative to the control test (vanilla)............im not sure im explaining my concept very well?!?!

ofcourse all the test results could be viewed in detailed view in the same sort of format as the xls spreadsheet??

This way a ROM can undergo a test with a custom setup on anybodys device and get a score to really see how it fairs against other ROMs? I personally see this as a similar sort of thing as PCMark or 3DMark??

EDIT::: just thought it would be cool to see how an app installed affects the XDA-Bench score?? Ive noticed certain apps tend to slow down the device whilst other dont?!
[Windows Mobile Development and Hacking General] KarhU:
Thanks for your ideas - Available benchmarks have something like synthetic master score (check my benchmark thread - link is in my sig). Slowdown measuring is also interesting idea. Hopefully somebody will make this xda-bench a reality ;)
[Windows Mobile Development and Hacking General] MaRaHoX:
Testing methodics

Hi KarhU,

I was thinking about it;) and one more thing about it - it is also really important to define starting point for this ROM - or better is to say "comparable state"... f.e. - to switch off all today items etc. I understand that for user is better to know how the ROM is powerful in real state... maybe to consider this note as a basic for discussion about it (if it is not already mentioned there or somewhere else;) )

Glad to help little bit with this important and purposeful work!

[Windows Mobile Development and Hacking General] uniqueboy:
I think the official HTC rom would be the best to use as a control rom for comparisons. I would run this app every time I install a new piece of software, at the moment my orbit is running a bit slow, I've just overdone it a bit at the moment, so it would be great to see exactly how an installation affects my system. It would be useful to developers and cookers alike. I hope the idea really takes off.
[Windows Mobile Development and Hacking General] galaxys:
This would be a great app if developed! I agree with a those above that the official HTC rom would be the best one to use as a control rom for comparisons.
[Windows Mobile Development and Hacking General] KarhU:
Interesting idea - currently my tests were done WYSIWYG method - I wanted to compare the ROMs with their basic settings to see actual performance in more "real life" conditions. You are right that if we want to compare the base there should be comparable testing starting point.
[Windows Mobile Development and Hacking General] ahlok_hk:
I suggest to add the following test for phone devices:

- time lag between 'caller heard first ring' and 'the device actually rings'
[Windows Mobile Development and Hacking General] KarhU:
This is a good one and very often people are interested in this statistics, but it is hard to measure as you need two phones.

[Moto X Q&A] gotling:
With my Moto X (Ghost) XT1052 I have strange problems installing custom ROMs and root.

TWRP

If using the latest stable TWRP 2.8.7.0 and trying to install CM13 I get an error message like this:

This package is for device: xt1052,ghost,xt1053,ghost_retail,xt1055,ghost_usc, xt1056,ghost_sprint,xt1058,ghost_att,ghost_rcica,x t1060,ghost_verizon; this device is )".

There is a thread about making changes to the updater-script to get around this problem which did not solve the problem for me, and I don't see it as a permanent solution.

What did work was to install an older version, specifically TWRP 2.6.3.1.

Question: Is there a solution to this problem with a specific current build of TWRP or have ro.product.device permanently set?

SuperSU

After flashing the latest SuperSU from TWRP and rebooted, the device just hangs on the boot logo and does not pass.

Using the much older SuperSU 2.63 works without a problem.

Question: Is there any solution to get the latest SuperSU installed?

Is anyone going to help me with this? I have a Samsung SM-T377V tablet and I'm trying to find out how to root it. Thanks!
[Galaxy Tab Q&A, Help & Troubleshooting] electronhacker:
I had luck a few months ago using Kingroot v4.8.5 after downgrading the stock rom to android 5.1.1 (verizon's official build which the tablet originally shipped with at launch, Build LMY47X.T377VVRU1AOL7).

More recent versions of Kingroot simply fail and do not work. Also, the newer builds of the stock rom appear to be patched and I was unable to root via any method so the downgrade is required. (use Odin to flash verizon's original build)

While Kingroot does shoehorn a working way to root a running system, root doesn't appear to stick forever and eventually did stop working for me. I did have enough root time to at least break google apps and disable other bundled apps from running, but I wasn't unable to fully uninstall all the google spyware and verizon cruft - very frustrating!

Kingroot seems to take advantage of a zero-day vulnerability to grant us a rootkit.

I didn't have much luck replacing Kingroot with Chainfire's SU binaries to keep root working with something known-clean and backed by the community, which is a shame since Kingroot does appear to be running in the background doing who-knows-what with said rootkit. If you need root, Kingroot will get us at least that, but it's a two-way backdoor we're opening up and is really not a longterm solution.

Unfortunately, verizon has the bootloader locked down pretty hard. There's no way to flash in a custom Recovery which would open the door for developing a custom rom for SM-T377V with root already built in and none of the google/verizon undesirables. The current bootloader simply rejects any of the custom recoveries I've tried to flash in since they don't pass Verizon's signature checks.

What we really need is help from someone with experience cracking Verizon's bootloaders.. This bit is above my head and I'm at a roadblock.
[Galaxy Tab Q&A, Help & Troubleshooting] augmentedchikken:
So you're saying that the only way to root the device is to downgrade to an earlier version of Android, and because Verizon locks down the bootloader to the point where it rejects any recoveries to flash an older ROM, it's impossible to downgrade?
[Galaxy Tab Q&A, Help & Troubleshooting] electronhacker:
Not quite:

We can flash official Verizon roms without issue since these are signed by Verizon and the bootloader will accept them and allow the flash.

Downgrade to the oldest official Verizon rom using Odin, and root with Kingroot v4.8.5.

It's not a permanent solution since root doesn't stick for much longer than about a week, and Kingroot is of questionable safety in terms of privacy and your data. This is the furthest I could get to developing a custom rom for SM-T377V with root already built-in which "just works".

The Verizon bootloader is certainly aware that Kingroot has done something nasty to the stock rom - during bootup it now shows an Unlocked Lock symbol and says "CUSTOM" before loading the Verizon bootup animation (the animation is part of the rom). This behavior gets reset when an official Verizon rom is reflashed. I'm assuming a new official bootloader (signed by verizon) is being updated as part of their package as well.

We need the expertise of someone with experience cracking a Verizon bootloader so that we can flash a custom recovery which will allow flashing custom roms and making full backups.

I did attempt to flash TWRP in via Fastboot using root on a running system to circumvent the boot process and signature checking, but I was unsuccessful getting Fastboot working. I'm not sure that Verizon allows Fastboots for this reason.
[Galaxy Tab Q&A, Help & Troubleshooting] augmentedchikken:
So there's no way to disable Verizon's detection system that would make it reset the to the stock ROM after installing the previous version? I don't think I'd be with it to have my tablet rooted for only a week.
[Galaxy Tab Q&A, Help & Troubleshooting] electronhacker:
Root is working for the SM-T377V!

!! Great news! Your curiosity got me thinking about this again, and I got root working fully!

We finally have a working Root for the Samsung SM-T377V Galaxy Tab E 8.0" (Verizon)!

The trick is to use King

o

Root. (not Kingroot)

http://www.kingoapp.com/

First, downgrade the stock ROM to the very first version that Verizon shipped with. Build RU1AOL7, dated 2016.02.11. It's about 1.5gig, and I have no way to host such a large file, so search for it before you ask for mine. I found it pretty easily directly from Verzion. Use ODIN to flash it, yadda yadda yadda.

Then, use the Windows version of KingoRoot to actually root the tab. You will need to enable Developer Mode and USB Debugging, which KingoRoot walks you through if you don't know how. Be sure to uncheck the "Install recommended software" checkbox to avoid the bloatware they try to sneak by you.

After it finishes successfully, reboot the tab. During the boot, a message will pop up that says Android is Optimizing 1 new app. Badda boom, you're rooted!

To verify, use a Terminal Emulator and type the command "su" and press enter. If you're rooted, the prompt will change from a $ to a #. I also recommend that you use a root check app to double-check what is actually installed. I used "Root Check" by gsmdev since it's completely free and no frills unlike the other hundreds up on the market.

I'm successfully uninstalling all of the Google spyware and Verizon cruft now without any hangups for the first time since getting this tablet :cool: It's not on the level of a custom ROM by any means, but this gets us a lot closer to that day!

Is that your rooted firmware or just the stock? I would really love if you could post your already rooted firmware that you are using because I keep getting stuck in bootloops with Kingoroot (I only get stuck in bootloops with the android version Kingoroot.apk, and Windows Kingoroot gives me a temporary Root and can't seem to figure out how to keep it rooted.

I wanted to ask you if it was possible for you to post your already rooted firmware of stock (5.1.1) since it is still Verizon I don't see how the Bootloader would lock me out. Would that work?

I also cleaned up my posts on this thread so they're not all over the place.
[Galaxy Tab Q&A, Help & Troubleshooting] tomiga:
Sadly things don't look too promising for this tablet, considering the bootloader's preventing us from installing custom recovery. Though, in theory, would it be possible to install a custom recovery by temporarily rooting, then using that to write a recovery.img directly to the recovery partition on the tablet? That'd get around the verification for installing custom recovery if that works...
[Galaxy Tab Q&A, Help & Troubleshooting] electronhacker:
Ugh. I'm seeing bootloops now too, even immediately after a reflash to stock and then running Kingoroot.

The stock recovery shows "dm-verity verification failed..." at the base of the window.

For those that installed Kingoroot, you can undo the boot loops by rebooting into stock recovery

Reboot, PWR + VOL UP + HOME, and select "wipe data/factory reset..." to pull out all the kingoroot binaries. (this step is necessary, unfortunately)

Then, PWR + VOL DOWN + HOME to go into boot loader mode, and use Odin to reflash the stock rom. This will at least get your tab back to factory stock.

I'm going to explore a bit more with Kingroot, I hadn't realized until I went to reflash over the bootlooping system that unless a full "wipe data/factory reset" is run prior to Odin, that most of the existing system remained intact. In my last writeup I did have a functional tab that could be rebooted without problems. I'm wondering now if it was a combination of the root tactics that I had tried earlier that were all still installed in the system that got things working....

When thing worked prior, I had been playing with: Kingroot 4.8.5, Official SuperSU, BusyBox-free, and of course Kingoroot

---------- Post added at 07:00 PM ---------- Previous post was at 06:54 PM ----------

These were my thoughts too. If we can get root, we can flash over recovery.img using ADB and/or Fastboot. The latter appears to be disabled/locked, however. Also, I'm not certain that the sm-t377p recovery image will actually work... They're reportedly the same hardware, but one cannot be sure that things will jive with a crossflash at such a low level. My thoughts were if it's even an option, gamble it, and if the tab is bricked oh well...

This tab is worthless to me anyway if I can't pull out the Google spyware. Should have bought a rootable Tab A anyway, it would have been cheaper :eek:
