[Sony Xperia XA Questions & Answers] Holmes.Sherlock:
I am trying to figure out the flow of execution of Xperia XA boot-loader after issuing `fastboot oem unlock` command. Rooting my phone, I have dd-ed the image of `lk` partition. Since the image not in any standard format, I have re-based it to a probable base address in IDA Pro. I have got mixed success. So far, I have been able to figure out the handler that takes care of `oem unlock` command. However, it looks to be messy afterwards. Surprisingly, IDA fails to find out no more than one XREF to the handler function which is seemingly unintuitive. Is there anybody willing to have a look (provided I share the IDB database)? It seems to be an interesting yet difficult exercise. Any clue, suggestion is appreciated.
[Sony Xperia XA Questions & Answers] bulanula:
Keep going mate, if you manage to find what makes it tick, you potentially might be able to unlock even the ones which have:

Bootloader unlock allowed: NO

Since Sony uses a similar bootloader protection for all its devices, irregardless of the platform (MTK, QC etc.)
[Sony Xperia XA Questions & Answers] boofman:
I'd love to help out as I've got an XAU with locked bootloader, but I've been out of the game for quite some time so those things are kinda out of my league right now..

However, I know my way around Linux so ADB isn't a problem..let me know how I can help..
[LG Optimus G Pro] RVC46:
I need ideas on how I can display my wife's contact information on my LG E980 lock screen as well as my medical information. Her iPhone has a convenient feature permitting this information to be accessed without getting past the lock screen. Any ideas how we can meet this need on a stock LG e980? Someone must have figured out how to deal with this issue here.

#2 - I want to add VPN to my phone yet, see no clear winner in the Google Play Store. I use CM security and was tempted to install their VPN service but, it does not look to be rated well.
[LG Optimus G Pro] ShadySquirrel:
There is "Owner info" option, somewhere in the lockscreen or display settings. It should be there even in stock ROMs, if I remember correctly...

About second question, I would avoid anything by Cheetah Mobile, but it's your device :D Don't know any good VPNs, Orbot+Orfox are working half of my needs, and uni's VPN other part.

Is it OK to downgrade from CM 14? I will replace recovery and wipe everything.
[Galaxy Grand Prime Android Development] melc70:
when it will be available .... I only found cm12.1

thanks to the work done
[Galaxy Grand Prime Android Development] joe_5579:
you shouldn't right now since the CM-13 Images aren't uploaded yet or in other words, don't downgrade until they are uploaded, then you can downgrade;)

---------- Post added at 06:49 PM ---------- Previous post was at 06:47 PM ----------

Ore you one of the ones helping to get booting cm13 images?I am hoping to have at least a testing build for my sm-g530t1 by January/February
[Galaxy Grand Prime Android Development] joe_5579:
No, I am not a helper of this ROM xD but hopefully we see something before then, but we also need to give him time too, and here, this is exactly what he said: "Whenever I have the time to actually fix any issues and get an image booting. The time will vary depending on various factors ( my mood, how much homework I have, how well fed I am, etc.. )"
[Galaxy Grand Prime Android Development] arnaudbails:
Nice Vince ! I will Help you as CM12.1 ! ;) thanks for your work ! ;)
[Galaxy Grand Prime Android Development] jdoggawesomex900:
As I can see main concern goes for building sm-g530w builds right now which apparently is the only one with a booting cm13 image right now
[Galaxy Grand Prime Android Development] joe_5579:
It bootloops.
[Galaxy Grand Prime Android Development] jdoggawesomex900:
Okay guys.They are making new cm 12.1 builds for all devices as we speak do still cm 12.1 .Soon after cm13 images will start.
[Galaxy Grand Prime Android Development] kentone:
Yep, we are fixing small bugs on cm12.1, doing final builds and preparing the environment for the cm13, also we are improving the telegram channel and other things. Give us time :cool:

litte question: what are the advantages from cm13?

I know it's better and I want it to but I don't know the advantages

[Galaxy Grand Prime Android Development] shakazoid:
Why would you suggest requiring an external app to enable root when it is disabled by default in CM builds. If you do not activate it , it does not come on and the presence should be undetected by any app till it is enabled.
[Galaxy Grand Prime Android Development] EthanCS:
It's still included in the ROM, though. Games that block root, such as Pokemon Go and Miitomo, don't detect root by asking for permission. They detect root by searching the device for any files relating to root. If you try playing Pokemon Go, you won't be able to get any further than the login screen.
[Galaxy Grand Prime Android Development] OrangeRaptor:
So I cleared the data and it still doesnt let me change any gboard settings.

[Galaxy Grand Prime Android Development] Slenderman8090:
Psst. You can get G530H Roms to work on G530T if it is unlocked (carrier unlocked) device will just be seem as G530H instead.

Hi again Vincent, I have figure out partially of the internal sdcard problem. But I cannot download to it. Currently, int_SD is stuck at /data/media/0 and I'm not sure how to change it.
[Galaxy Grand Prime Android Development] Rebel7022:
I had to go stock for a hour and when I reflashed lineage for g530t, the home button won't work and I can't pull My notifications down.

help, i dont speak english

Greetings, this version works with a prime metropcs g530T?
[Galaxy Grand Prime Android Development] Slenderman8090:
As discussed before, flash LineageOS, set it up, then flash gapps.

I tried flashing this ROM onto my 530T1 through TWRP but it's been sitting at this screen for at least 20 minutes. See below. Any help would be appreciated. Thanks.

please help

Hi I also have a g530t1 (metropcs) with stock software, you could be so kind to publish a tutorial step by step from 0, I only have root access, I would appreciate it very much because I do not get reading material about this mobile
[Galaxy Grand Prime Android Development] Nicky Carts:
[MENTION=7569388]vince2678[/MENTION]

Thanks for helping me get past that point. However now I'm on another problem. This is what I've been doing, I've been formatting the disk to do a completely blank wipe and then flashing/installing "lineage-13.0-20170130-NIGHTLY-gprimeltemtr.zip" via TWRP. That goes fine but then when I enter the Google setup wizard, after it takes its time preparing "110 apps" I get the "Unfortunately, Setup Wizard has stopped" message towards the conclusion of the setup wizard. This along with the fact that the background is completely black. Probably no launcher or something. See video below.

I have a suspicion it might have something to do with the GApps because earlier this morning I had this ROM flashed successfully (with your advice) and it only needed to prepare approximately 30-40 apps. I then proceeded to flash GApps successfully, followed by a TitaniumBackup restore which most likely created the conflicts by loading previous Google Apps + data.

At this point, any help would be appreciated. But if you can point me in the direction of how to completely start from scratch, that would be great. From there I'll just flash GApps again and then download the apps manually via the Play Store since this is my dad's phone and didn't have much going on to begin with.

[EDIT: 2-5-17 @ 11:50AM EST USA] Well I managed to successfully flash LineageOS again partially get past the point I mentioned. I don't know if it was sheer luck or the slightly older build was the problem. I flashed "lineage-13.0_j12_20170131_NIGHTLY-gprimeltemtr" instead of "lineage-13.0-20170130-NIGHTLY-gprimeltemtr.zip". Now I just need to work on flashing GApps.

[EDIT: 2-5-17 @ 12:15PM EST USA] Looks like the slight build difference was all that mattered. At least for me. I can't speak for other users but if there's folks out there using the MetroPCS variant of this phone, SM-G530T1, I'd highly recommend going with the absolute latest build of LineageOS from 1-31-2017. Seems to have been the root of my problems, pun intended.
[Galaxy Grand Prime Android Development] vince2678:
Read the OP.
[Galaxy Grand Prime Android Development] Rebel7022:
G530t I installed the 2-6 update and it keeps saying sd card corrupted, so I installed a older version of the rom and everything is works.
[Galaxy Grand Prime Android Development] Rebel7022:
G530t. Hand wave to wake screen isn't working, my screen never turned back on and i had to pull the battery out to fix the phone, also the rom is saying my second partition on my sd card is corrupted, so I reinstalled last version and everything worked.
[Galaxy Grand Prime Android Development] vince2678:
The only changes done were refactoring/organisational changes to the repositores and a regular LOS security patch update. If you're experiencing a problem it's most likely an error due to something on your phone and not the ROM itself.
[Galaxy Grand Prime Android Development] Rebel7022:
I clean flashed today's update and on first boot it tells me corrupted sd card, its my second partition that I can't access, so I clean flashed your last update on the 30th and sd card works fine, also my phone got really hot and screen wouldn't turn on, on today's build, that didn't happen once on previous builds with the same setup. Anyways thanks for your response.
[Galaxy Grand Prime Android Development] Slenderman8090:
You see vince this is what I was talking about, I was talking about the Internal Storage Partition. The partitioning system is a bit wacky at the moment. Sdcard0 can be accessed through /data/media/0 but isnt actually writable. Im not quite sure on how to fix this issue. So Rebel7022, id just recommend switching into CM12.1 until this gets figured out. Vince, I hope to see a fix for the T-mobile Variant of LineageOS. Also you can do so via this Link here.

---------- Post added at 08:30 AM ---------- Previous post was at 08:25 AM ----------

Also Vincent, the website is down for the Updates and such. Just letting you know just in case you dont already.
[Galaxy Grand Prime Android Development] OrangeRaptor:
So far I've found that the clock doesn't work (crashes instantly when opening), GBoard settings crash, can record video because it tried to record in 60 fps, and no root. I will post more updates once I find more problems, but so far its still very usable.
[Galaxy Grand Prime Android Development] vince2678:
That's not a problem with the ROM, that's to do with the GApps package replacing system apps that come by default.
[Galaxy Grand Prime Android Development] OrangeRaptor:
How can I fix it
[Galaxy Grand Prime Android Development] are2325:
saludos, tienen algun video de la rom corriendo en el grand prime, 100% estable o aun no llega a ese nivel, disculpen solo que ese movil es muy costoso en mi pais y no quiero arruinarlo

---------- Post added at 12:42 PM ---------- Previous post was at 12:36 PM ----------

Greetings, have some video of the rom running in the grand prime, 100% stable or even does not reach that level, sorry only that this phone is very expensive in my country and I do not want to ruin it
[Galaxy Grand Prime Android Development] Noe Morin:
My Gapps were also being VERY buggy. (Gboard app crashes, clock app crashed, etc..) all I did to fix it was do a clean flash and re download the Gapps and it was fixed
[Galaxy Grand Prime Android Development] OrangeRaptor:
How did you do a clean flash? And what Gapps did you download?
[Galaxy Grand Prime Android Development] Noe Morin:
You basically just wipe everything and flash the ROM again.. I used the Gapps from the open Gapps site
[Galaxy Grand Prime Android Development] shakazoid:
Was unaware of that. Thanks for notifying. Will keep an eye on that if I ever come across it when troubleshooting issues.
[Galaxy Grand Prime Android Development] :
STEP 1:. On your phone, open browser and go to opengapps.org

STEP 2:. Make sure the platform is ARM and the version 6.0. Now comes the Variant, I used micro but if you just want the playstore then take pico.

STEP 3:. Move the downloaded Gapps zip file to your microSD card. You will also need to move the ROM zip file there because once in TWRP you will wipe all partition except the microSD card since you'll install the 2 zip from it. What we call a "clean flash"

STEP 4:. Reboot into recovery (TWRP)

STEP 5:. Click on "Wipe" then "Advance wipe"

STEP 6:. Tick all partitions just not the microSD. When done return to the main menu.

STEP 7:. Click "install" then "external sd" Flash the ROM zip first. When done, go back and flash Gapps.

Reboot System and Voilà!
[Galaxy Grand Prime Android Development] are2325:
Greetings, what is the status of the rom for the g530t1 metropcs?
[Galaxy Grand Prime Android Development] Nicky Carts:
I put "lineage-13.0_j12_20170131_NIGHTLY-gprimeltemtr" on my dad's phone and its very stable. There's some newer builds out and I would imagine they're just as stable. I just don't plan on regularly updating the phone since it belongs to my old man and he isn't the type to care. If you're into rooting and want a modern ROM as opposed to the one that the phone comes with, I would highly recommend it. Very impressed. :svetius:

[Galaxy Grand Prime Android Development] Rebel7022:
Is there a fix for the sd card corruption notification ?
[Galaxy Grand Prime Android Development] vince2678:
That's not an error, it probably has to do with how your SD card was formatted. If the phone can't detect a partition table it will complain about a corrupted card. If you want it to go away you can move your files and have android format the card.
[Galaxy Grand Prime Android Development] Rebel7022:
Ya I did that. Also on previous builds of this rom sd card works, but ya after I formatted still the same, I hope you can fix it before you move on to 14.1 cause I'm loving this Rom
[Galaxy Grand Prime Android Development] Rebel7022:
g530t, i just downloaded the unified update and md5 file , it just says patching system image unconditionally
[Galaxy Grand Prime Android Development] vince2678:
I've addressed this before. Your download is corrupt. Download both the zip.md5 and the zip again, push them both to the same place, then try flashing again after.
[Galaxy Grand Prime Android Development] Rebel7022:
I downloaded rom and m5 file 3 different times, still the same thing patching system image unconditionally, is there a work around I can do to get the zip to flash?
[Galaxy Grand Prime Android Development] vince2678:
I'll make an ODIN build but only this once.
[Galaxy Grand Prime Android Development] Rebel7022:
The Odin file failed
[Galaxy Grand Prime Android Development] vince2678:
Thanks. It seems some critical system files weren't getting copied. It should be fixed in the next build.
[Galaxy Grand Prime Android Development] Zippy Dufus:
The unified build looks interesting.

Does this mean that the manifest will be unified as well with the device-specific projects deprecated and removed? (I spotted your new Galaxy-MSM8916 repos.)

I have yet to get an working cm/lineage 13.0 working build (latest attempt 02/13) as it gets the the final step of "Starting apps" and hangs. The device is booted though because I can access via adb and the logcat shows repeated:

2-12 16:06:42.705 19351 19351 V CameraWrapper: camera_get_number_of_cameras

02-12 16:06:42.705 19351 19351 V CameraWrapper: check_vendor_module

​

I suspect that I am missing or have an out-dated version of a critical (firmware) file. A straight comparison of sorted file lists from both yours and my build doesn't reveal anything so now I am looking at the sha1sum comparisons.

Hacking is fun! :cowboy:

Status of the 2-13-17 update for the tmobile variant?

G530t build 7 Odin build failed and the zip stops at patching system image unconditionally.
[Galaxy Grand Prime Android Development] angel4hire:
Any way to increase the in-call volume though build.prop? Mine is barely audible even at max volume.
[Galaxy Grand Prime Android Development] vince2678:
Hmm, I found the issue. I didn't update the system partition size, the images were too large for the t/t1 system partitions.

Can you flash a backup/stock image with odin, make sure it works, then flash the upcoming build.
[Galaxy Grand Prime Android Development] vince2678:
Are you sure you're applying all the patches, aren't missing a repository (msm8916-common, gprimelte-common), are using the correct kernel (msm8916) and that boringssl-compat and stlport aren't missing?
[Galaxy Grand Prime Android Development] Rebel7022:
Yea. Where do I get the backup/ stock image to flash with Odin?
[Galaxy Grand Prime Android Development] vince2678:
Just a TWRP backup if you have one, or a stock image for your phone if you have that as well.
[Galaxy Grand Prime Android Development] Rebel7022:
I don't have a backup and there's a storage issue with the last couple of builds so twrp won't let me make a backup, I flashed your 12.1 with Odin, I'll test your next build no problem

[Galaxy Grand Prime Android Development] Nicky Carts:
TWRP 3.0.2.0. Didn't have any problems.
[Galaxy Grand Prime Android Development] EthanCS:
Two bugs:

1. The sound in Color Switch sounds strangely static-y. It's really noticeable over the music, which sounds normal.

2. The screen flashes white briefly when the screen is woken up.

Also, some suggestions:

1. The preferred network type should be set to LTE by default, rather than 4G.

2. Some settings that don't apply can be removed from Settings, such as Buttons > Backlight (since the Grand Prime has no button backlight).

3. It would be nice if the root indicator could be removed from the status bar (like every other indicator can be removed).

4. Recent changes to LineageOS should be merged into this ROM, including Sound Recorder and Screen Recorder being merged into one app.

5. As I suggested before, the ROM shouldn't have root by default, since some games don't allow root.
[Galaxy Grand Prime Android Development] vince2678:
I don't know what color switch is.

If you've checked, you'll notice root is not included by default anymore.
[Galaxy Grand Prime Android Development] EthanCS:
It's a mobile game on the Play Store. You don't even have to play it. You can hear the static in the menu sounds.

I just did a (conveniently timed) fresh install of 20170212 and I still have root.
[Galaxy Grand Prime Android Development] vince2678:
Please, and let this be a standing policy from now on:

If you post a bug description, get a logcat PLEASE. I'm not a shaman. I can't guess what's wrong with the rom all the time. If this is not satisfied I will not look into the problem or reply the offending message.
[Galaxy Grand Prime Android Development] vince2678:
On the unified builds at least. I don't think the prior builds have root removed.
