Eventhough I have done a lot of search in samsung galaxy J2 ACE (G532G),couldn't find a single forum ,post,tutorial in name of J2 ACE..There are rooting tutorials only available for J2 PRIME (G532G),which is a similar ROM variant.I have tried many of J2 Prime tutorials and end up in bootloop/boot lock screen.So requesting XDA developers to help me in creating prerooted firmware.I have added stock roms's google drive link.

Its a stock ROM of J2ACE .I downloaded it after i got into bootloop .Flashed in my J2ACE mobile ,verified working good.

https://docs.google.com/uc?id=0B5BpnlH8S_TWUW51RmNqWmFDNlU&export=download

Any developer kindly use above ROM and create a prerooted ROM.As without root ,the stock marshmallow 6.0.1 ROM filled with bloatwares of samsung ,which are memory eaters.I got left only 500mb,if I add any four or five apps,out of 8GB internal memory.SD card also write protected.I couldnt install and use whatsapp, bcz I end up in exhausting free memory to 50mb.

Please ,any help greatly appreciated by few thousand users of J2 ACE out there.

Below are J2prime G532G tutorials ,I have gone through.I request other J2ACE holders not to give them try.If you have tried them accidentally and ended up in bootloop or boot lock screen,Kindly use ROM from above drive link and flash it with ODIN.

1.Rooting Method of G532G/H/M.(Tried this method and end up in Boot Lock Screen)

https://xdaforums.com/android/development/root-samsung-galaxy-j2-prime-g532m-t3523090

2.ROOT G532G WITHOUT BOOT LOCK PASSWORD ( But it does get into Boot Lock)

Solution :

Video tutorial on flashing J2 ACE stock ROM flashing,If you get "Set Warrenty Bit void" KNOXX error by flashing and also for BOOT Lock Screen,

https://www.youtube.com/watch?v=a5Q9JJwunZM&feature=youtu.be

There is people out there saying use Z3x Box to unlock Boot Lock screen .But it does cost 10,000 Indian currencies ,more price than that of J2 ACE mobile price.Also there is 'no box' version of Z3x samsung tool v24.3 available over internet ,which unfortunately doesnt support G532G Unlocking.There is no latest version of Z3x tool 27.00 without Box available so far.No local unlocking vendors/service centers, i could find in south indian cities around me.So Pre-Rooted ROM is the only hope of People buying Middle end budget phone Samsung Galaxy J2 ACE(G532G).

- After installing rom, Make sure you dont download any ota update from samsung (very Important)

- Boot your phone into download mode, and flash the twrp recovery. (you can search on google for that and if still you dont get it comment back i will give you download link)

- This time you will see that you phone doesnt go in boot lock (Yellow warning appears but not red one)

- Now boot into recovery by ADB and you will have twrp recovery

2 methods for TWRP + root

I am using the stock ROM you so kindly have made available.

The first method I have tried with success is "EASY-G532-TWRP+ROOT-NEW". There are an exe file and an MP4 file in the folder. You only need to have Samsung USB drivers installed on your PC. Connect your phone to your PC - normal mode. Play the media file for instructions. Your phone will be rooted witin

https://www.dropbox.com/sh/xjdt8rhw2mme9xy/AAD6S10PRyw3FYQ5yHRVmZfFa?dl=0

The second method is quite simple.

- flash TWRP via Odin

- in recovery mode, flash SuperSU and then no-verity-no-encrypt.

Done.

[Samsung Galaxy S8+ Questions & Answers] badjoras:
The differences are only 3, as far as I can tell:

Snapdragon vs Exynos

6gb Ram vs 4gb Ram

Community support

Exynos is faster than snapdragon, overclocked or not (mine is overclocked to 2.5 ghz and does 182k on antutu, same battery life).

6gb ram is better if you need to use 10 apps at the same time, because it will need to reload apps less often (although I havent seen my s8+ exynos reloading anything so far)

community support is better for exynos than snapdragon, that's for the normal ones... imagine a specific model with a snapdragon.

If it were me, I would spare myself the trouble of getting a phone that will only be sold in korea or China and avoid potential problems that will take longer to be solved than if you got a national phone (even if the bands are the same). I would get the 955F (well, I have it xD)
[Samsung Galaxy S8+ Questions & Answers] riz157:
The reason I was considering 9550 as blue coral is only available in that version.

I did go for 955FD gold in the end as that colour isn't available in the UK yet.

Useful info just one correction g9550 also comes in 4GB ram too.
[Samsung Galaxy S8+ Questions & Answers] Alcibiade:
I have the 9550. Didn't really have a choice since I live in Hong Kong. I do prefer the exynos too, although kind of doubt it makes a big difference (probably slightly better battery life).

Completely true about the community support although you can expect part of the Chinese community to actually support the device.

It will probably also take longer to get a root for this device than on Exynos (if we ever get it... Which starts to stress me out)

One small caveat: the Snapdragon has a better support than exynos among app developers and you can expect to have better optimized apps for the Snapdragon version (but this too is probably a minor thing too...)
[Samsung Galaxy S8+ Questions & Answers] jalyst:
I don't see how that makes sense, I don't suppose you can elaborate on why you think this is correct?

TY/BR.
[Samsung Galaxy S8+ Questions & Answers] Alcibiade:
Certain 3rd party camera apps for instance take advantage of the snapdragon. Google TensorFlow for machine learning as well. Other apps leverage on its DAC.

I hope now that makes sense to you. If it doesn't, use Google.
[Samsung Galaxy S8+ Questions & Answers] jalyst:
Cheers! I wonder why Exynos has worse support for those sort of things, poorer dev SDKs/APIs? BR.
[Samsung Galaxy S8+ Questions & Answers] Alcibiade:
Most likely Qualcomm's effort to distribute their API and document their processors (Samsung doesn't publish everything about the Exynos). Also easiness of users reach for developpers: if you develop something optimized for Qualcomm you know you will reach US Samsung's phones, HTC phones, Pixel, Moto, etc... And you probably don't want to make the effort to see if there is an equivalent API available for Exynos, learn it, debug your app for it while it will allow you to reach only a limited number of users.

These are anyway most of times optimizations that allow faster processing and don't necessarily take away any functionalities (So in most cases it wouldn't even get noticed)
[Samsung Galaxy S8+ Questions & Answers] jalyst:
I see, I suspected it'd be something like that, thanks for taking the time to explain further why you think it's the case! BR.
[Samsung Galaxy S8+ Questions & Answers] Alcibiade:
Latest example of this:

https://androidcommunity.com/google...comm-snapdragon-820-821-835-devices-20170814/

Won't happen for Exynos. With Google certainly optimizing a lot of its next apps for Pixel 2, you may soon see more coming for Snapdragon 835. Typically I wouldn't be too surprised if we were to get this for snapdragons: http://news.mit.edu/2017/automatic-image-retouching-phone-0802

To my surprise, the Snapdragon seems to be ahead this time...

Sigh...

If only I could get a G9550 easily into Australia, none of the specialist importers were offering the 6GB + 128GB version, plus it was missing one critical band, in-the-end I was left with no choice but to get an imported G955FD. [only single SIM version officially sold in Australia]

The only place I could find it in the world where I could have had it shipped, was India, but the average cost of top-end smartphones there is

much

higher than it is in Australia, postage plus MF services wasn't too bad.
[Samsung Galaxy S8+ Questions & Answers] MeltdownSpectre:
FYI, the 6GB/128GB G955FD S8+ is now available in Brazil as well, hopefully Samsung decides to launch it in other markets like they did with the 128GB S7 edge.

Hi,

Since the Nougat version doesn't have xposed yet. I was not able to use the YouTube background play module, however, I stumble upon this thread and was able to download the moded YouTube app.

The link for the app

https://www.androidfilehost.com/?fid=745425885120733599

Steps

1. Download the app.

2. Rename it to YouTube

3. Replace it in /system/app/YouTube folder

4. Restart the device.

There's a catch however on our 6X.

You play the video, then press recent key and then home key. If you directly press the home key the video won't play in background.

This is the PX 5-2G HA unit Marshmallow ROM I own.

And this is JOYING's FYT based PX5 unit.

It is obviously a problem of ROM that oreo ROM can not use GLONASS. If you want the accuracy of the position information downgrade to marshmallow or buy a FYT unit is early.
[MTCD  Android Head Units Q&A] kesztió:
Thanks, Warata, but I still have some problems and questions.

1. The “good” configuration with Marshmallow on your photo still shows an accuracy as bad as 6 m. And no words about SBAS, Beidou or Galileo satellites.

2. I think the PX5 bord revision is very important: I have REV 8.0, something like this:

[IMG="this"]https://images-na.ssl-images-amazon.com/images/I/81v1tyQS%2BsL._SX679_.jpg[/IMG]

which is based on U-blox NEO M8, while REV 4.0 still uses U-blox 6 or 7. Are you sure they use all the same revision?

3. Is it safe to downgrade across different manufacturers but same PX5 board, same revision? If so, do you have the downgrade kit for Marshmallow in order to make me sure this is the problem? (It should be an update.zip of approx. 1 GB, I’d greatly appreciate if you sent me it by wetransfer, zoltan .at. studiorip .dot. com.)

4. The “native” U-blox application (u-center for windows, you can access the android unit by the U-blox droid center, if both are in the same TCP subnet) shows a bit different: Both GLONASS and GPS are used simultaneously, I can see 2 SBAS satellites, and things get even better if enabling the full power mode. Does it mean that the U-center can bypass the Android driver?

5. Wouldn’t be enough to change just the Android driver, not the whole OS? If so, do you have a clue, how the original U-blox Android driver can be purchased?

Thanks!
[MTCD  Android Head Units Q&A] warata:
Photo 1 and Photo 2 are definitely the same HA unit. Only the difference in firmware. So I can assert that it is a firmware problem that GLONASS can not be used with oreo.　PX5- 4G-KLD Oreo I purchased recently was also unable to use GLONASS.

I upgraded marshmallows to Oreo using the kumarai's upgrade kit.

https://xdaforums.com/android-auto/mtcd-software-development/px5-oreo-rom-t3736950

I attempted to downgrade PX5-4G-GS oreo unit to marshmallow in the same procedure, but that did not work.

JOYING's FYT based unit is totally different on the same PX5, and both GLONASS and BeuDou can be used. However, other satellites can not be recognized.

Other questions are beyond my knowledge. Please wait for other respondents.

[MTCD  Android Head Units Q&A] 96carboard:
Its not really appropriate for GPS to output accuracy in a distance unit. What they output is a level of "confidence" that you are within the GPS's rated accuracy of the position being reported. You can't translate from that measure to a distance unit, so they make something up, usually based on a linear multiple of the rated accuracy.

For instance, it may give you a 50% confidence of being within 6 feet of the reported coordinates. Or it might give you a 90% confidence that you are within 6 feet. In either case, you could very well be within the 6 feet, and in fact, you could be "dead on", but it can only provide you with a probability. Despite that, it may present 50% within 6-feet as a 20 foot radius, or 90% within 6-feet as a 7 foot radius.

Don't get too overly hung up on it. If you want a better idea about how close the GPS reads to reality, open up google maps in satellite view mode, and see how close your physical location is to the center of the target based on landmarks.

---------- Post added at 05:23 PM ---------- Previous post was at 05:18 PM ----------

Are you sure its really a U-blox? U-blox GPS receivers are among the most notorious for counterfeits. They use some crappy nobody brand gps receiver, and program its microcontroller to communicate as a u-blox.

https://www.u-blox.com/en/counterfeit-products-and-u-blox-brand-misuse
[MTCD  Android Head Units Q&A] kesztió:
I cannot be 100% sure but in U-center it declares itself to be at least M8030 (Actually nobody pretended to be NEO 8M, it was just my thought), and with a correctly placed antenna it indeed can get 100% inside a 2,5 m diameter deviation map, at least for 20-30 minutes. So co-operating by u-center is not an issue. (Though on just 2 Hz with multi-GNSS config (GPS + GLONASS) all GLONASS satellites suddenly die.)

The big problem is with all other 3rd party applications.

Here is the text output at startup:

So do I have a counterfeit version or not?

*UPDATE* I forgot to update the baud rate to 19200 baud, that’s why the chip apparently hasn’t been able to face 2 Hz multi GNSS. That is, it’s almost sure that the chip is not NEO M8, “just” naked M8030, but at least I simply don’t think such a widely used board like PX5 uses fake M8030 chip. This is ridiculous.

[MTCD  Android Head Units Q&A] 96carboard:
The notion of "accuracy" in GPS is not nearly as straightforward as you may have been lead to believe. In fact, most of these GPS HAL's will be fudging the accuracy based on the HDOP value. HDOP means "horizontal dilution of precision". While a smaller DOP value does typically indicate a greater precision, it is in NO WAY related to horizontal accuracy in terms of an actual distance, which is what Android reports.

In other words, if you're using an NMEA GPS, then you can basically ignore the reported accuracy in Android -- its meaningless.

Now there are ways to get more reasonable values, but this requires you to deal with the binary format that is output by your GPS module, not the standard NMEA output. For example, using the gpsd Android HAL (https://gitlab.com/gpsd/gpsd/-/tree/master/android), because gpsd uses the binary format for some GPS units (ublox in particular), it will output a reasonable distance for accuracy.
[MTCD  Android Head Units Q&A] fratellos:
Very interesting ! Can you tell us how to do it on ours devices ?
[MTCD  Android Head Units Q&A] 96carboard:
If you can build Android from source, you just add gpsd to your local manifest and device makefiles, and remove the nonsense hal they previously included. However, as this thread appears to be related to chinese "px5", its not that simple. I'd say you would have to build it in AOSP, then manually copy in the files needed for it.

But the bottom line is really this; you don't actually need to do this. Making the accuracy values correct won't change the actual accuracy of the gps output, so all you really need to do is IGNORE the accuracy value.

If you want to get a picture of what the actual accuracy of your gps is, hook it up to a gnu box, let it get a fix with gpsd, and see what accuracy it spits out, then just remember that number and substitute in your head.

Automotive navigation doesn't actually require all that great of accuracy. If its accurate to within a few HUNDRED feet, that's good enough, because the software will snap your location to the nearest road anyway.
