Tab Pro 8.4 Needs an upgrade. Cyanogenmod 13?

I've had this tab for awhile now and the lack of updates wasn't an issue for me while my Nexus 7 was still my workhorse. USB port and charging issues has forced me to use the Pro almost exclusively now and it's frustrating. I'm thinking CyanogenMod 13 because it's available and the latest version of android. But I have a couple questions. Please help. I've searched and will continue but a little help would be appreciated.
Internal storage is at the top of my list right now and I believe Cm allows the ability to use SD card as internal storage. It's available in CM12 but apparently not CM13 as it sits as a nightly. Is this still true? I'm going to flash this tab today. Would rather go with 13 but I'll flash a stable 12 because I need this ability.
This isn't really that important but would help with dealing with all my remote controls. Does Cm now have the ability to take advantage of the RF sensor for remote control? In the past it was always blamed on closed source drivers. Still an issue or no?
Thanks for your input. After being away from the scene for awhile I've answered most of my questions. These are the last two.

I have the CM13 version from about a week ago, and it has the option for using the SD card as internal storage. As for the IR blaster, there are a couple of apps on the play-store that worked with CM12, so I assume they will also work with CM13.

Thank you! Guess I'll grab a 13 nightly and get to work :good:

Hey guys. The install went smooth but I'm getting parsing error when trying to install apps from unknown sources. In particular right now I'm trying to get PS Remote Play setup but the only remote app I can get to install needs updating. Every single other download I've tried has failed due to parsing error.
Edit: Now I'm stuck. Cm13 is running fine. Rooting was smooth, flashing Twrp 3.0.0-2 was smooth. But then I started installing my apps from unknown sources. Parsing errors even though it's set to allows unknown sources. Hours of searches, tons of articles dealing with parsing errors and everyone recommends check the unknown sources box. Nice!
During this process I've booted into recovery and even though it worked fine before now it freezes in different areas. The menu will sometimes freeze right away or wait till I try and reboot into recovery, OS, download it doesn't matter. Reinstall Twrp and no change. I originally used Flashify but also tried Twrp manager which was worthless. Shocker.
At this point I want to just start over but I have zero confidence in Twrp. Or is maybe because of flashify? I'm lost. Is clockworkmod available? Most likely regardless of my thinking I'm missing something here. I just need a fresh start. How should I start. I need a recovery first.

Are you flashing TWRP 3.0.0.2 every time? I wasn't even aware they had a 3.0.0.2 build. And once in a while, they release a build with some problems. If you haven't already, try 3.0.0.0. I'm still back on 2.8.5.0 and no issues like you describe.

Yeah but its 3.0.0-2. https://dl.twrp.me/mondrianwifiue/
Somehow I got it all worked out. Starting over from scratch. The problem now is how to update to more recent nightlies. TWRP doesn't see any files anymore.

I don't know why they just switched from the last digit in the version number being -1, -2, etc, instead of .1, .2 (dash instead of dot) which they used for years.
But that misses the point. If you are having trouble on a brand new TWRP version, try a previous, known good one.

Yeah I got ya. I may try another one. Problem is I couldn't begin to guess which one is a "known good one". I know I've used a few starting with a 2.8 something up to the one I'm using now. None of these were even able to get me this far. But thanks

You have the right location selected, correct (internal storage vs. SD card)? A number of times, I've switched the location in TWRP, then forgot to change it back and scratched my head wondering where the files went.

Yeah I ran into that as well. I can assure you now its set correctly but I did experiment with placing the zip file in folders on both.
I got fed up last night and just started over. I flashed back to stock, Rooted, and flashed TWRP 3.0.0.0 this time and it worked! Installed CMs latest nightly and im up and running. Havent tested yet to see if zip files now show up in TWRP. Ill be looking after lunch

If you don't know if zip files show up in TWRP, how did you flash CM? Did you sideload?
To be clear, when you were having trouble seeing zip files in TWRP before, it was using the "Install" function in TWRP? Or were you trying to "Restore"?

Because adopted storage wasn't setup till after CM13 was installed. Adopted Storage is the key in this whole mess. Unfortunately for me its also the one key component I need to make this tab last me another year. What I was trying to do was flash the latest nightly with TWRP. That's when I realized TWRP couldn't see any of the files in any folder.
But get this. I forgot to repost after lunch. Seeing as though this time I successfully used 3.0.0.0 to flash CM I thought my chances of it seeing a zip file were pretty good. And it did! But then it freezes. Multiple reboots and all attempts to select a file or folder resulted in TWRP freezing. But at least 3.0.0.0 seen the files as you would expect. Maybe I should give 3.0.0.0-1 a shot again.

Depends do you have the T320, or the T325? AFAK the newer version of TWRP is ONLY for the T320. Having installed it to my T325 I lost my Recovery. thankfully I was able enough to recover it by flashing 2.7.8.x though Odin again in Download Mode. Not sure what was so special about the T320 that it needed a point realese fix for, that the T325 never got.

I have the T320

At the risk of adding confusion to this Thread, it seems that the T325 version of TWRP was also recently updated to v3.0.1.0 recently.
Since that's the version I'm running,
FYI:
mondrianWIFI = T320
mondrianLTE = T325
The trick here is to google mondrian<INSERT DEVICE> TWRP, which should take you to the direct download page.
To flash from rooted stock you'll need a *.img.tar File, with which to flash from Odin. In my case that would apply to v2.8.7.0 (IIRC).
Once that's been installed you can just use *.zip Files from within TWRP to update it.

Just to be clear. There was no problem flashing CM13 from stock with TWRP. Its not till the flash is all done and I selected to adopt SD card as internal storage. Then regardless of TWRP version it either won't see any files or and I've only been able to get 3.0.0.0 to see files but it freezes.
Here's the question. Are you using adopted storage?

no not yet, I'm still kinda stuck on a 32GB card that I've had since my S1 days. I'm kinda hoping to pick up a 64GB MicroSD for that purpose soonish though.
But, just outta interest, you wouldn't have happened to have Device encryption enabled, would you? As for myself I managed to figure out that if you encrypt the Device early enough (i.e. before you root it), the GSM \ Data Connections still work. Where as if you do it post root, it would kill those functions. (Not that a T320 User should care though).
But, the other side effect of encryption (of the /data Partition), is the loss of said /data Partition under TWRP. Which can no longer 'see', what it thinks should be a valid /data Partition. So reports back to you a 0kb free (e.g. not found).
Now like I have stated I have not used any features which would marry my MicroSD to the Device, yet... But if I had then as I understand how Google implemented Adapted Storage to work. then it would be reasonable to assume that it would become part of the /data Partition.
So to get to the punch line... is your Device encrypted? If so that's your problem right there.

No I haven't encrypted it. Its on my list of things though. I just didn't want to overcomplicate things at this point. I felt as though I was already pushing pretty hard with the CM13 nightlies and adopted storage. I'll tell you this much though. I said it before and I'll say it again. This thing has never ran so well. Also for the first time since I've had it storage is not an issue.
I'd seriously recommend the Samsung Evo+ micro SD card. I haven't noticed any issues with lag when loading or using any app. Since I've installed this setup a few times now though I noticed that when you do select to adopt storage and it tests your card, pay zero attention to what it says. Same card and twice it said the card was too slow and twice it said nothing. There's a flaw there I think. It alternated. First time the card was too slow but the second time there wasn't a problem and so on. Then again maybe not. Could be the SD card that's causing that. Ahhhhhh who knows. Lol

Hi Folks:
I had been running CM12 and deciding to upgrade to CM13 last night as the several issues seemed to have been addressed most recently in the most recent string of Nightly's.
I followed the instructions from RootJunky dude and all went just fine.
HOWEVER
I lost my root in the process. Not pleased about that.
Any way to get it back now that I'm on CM13, or do I have to roll it all back via a recovery?
Thanks for your assistance

Help - Galaxy Tab S 10.5 Bootloop Out of Nowhere

So...
Last week, my wife's Tab S went into a bootloop. She runs complete stock, we haven't rooted, or anything. There had been a notification about an update, but she hadn't touched it. She'd updated to Lollipop at some point last year, but hadn't applied the absolute latest update. One day last week, she just turned it on, and it started bootlooping.
Because it was so stock, there were no backups, no nandroids, or anything like that. No Custom Recovery. I told her "well, we can just do a factory reset. You'll lose everything, but once we get you back up and running, it'll just re-download everything from the Goog." So we factory reset it. Looked good for a minute, booted into the first screen, enter in your Wi-Fi password, all that. As soon as we got the Wi-Fi password entered, however, it re-booted. And keep rebooting. Bootloop city. No problem. I walked her through (over the phone) using Odin to flash the latest Lollipop firmware. No dice. It appeared to flash successfully, but still bootlooped.
Over the weekend, I tried using Kies to flash the most official firmware I could find. Everything was successful -computer recognized the device, was able to download "direct from the source," as it were, but it got stuck at 69% twice before failing. I read somewhere that one had to run Kies in administrator mode to get it to successfully complete. So I did, and it got past 69%, successfully completing the flash. STILL NO LUCK. STILL WITH THE BOOTLOOPS.
Last night, I realized that I hadn't flashed in Odin using Administrator Mode. Tried it, using latest 5.0.2 (XAR-Cellular South). Flashed successfully, all appeared well. Still bootlooped.
So, I'm stuck. I can get into recovery, I can get into Download Mode, I can successfully flash. I just can't get the darn thing booted.
Thoughts, anyone? Should I try flashing a Custom ROM? How hard is that using Odin? Thanks in advance.

Ok this will take a few tries but here is my method of dealing with this situation
1) Flash stock using Odin
2) AS SOON AS the screen goes blank, start holding Power+Volume Up+Home
3) When recovery boots, release the buttons
4) Use the volume buttons to select "Wipe data/factory reset"
5) Press power to confirm
6) Reboot
If that doesn't work, you may either:
1) (more likely) Installing a ROM will fix the problem
2) (unlikely but possible) You might have worn NAND pages, which I doubt but could cause this behavior.

Thanks, I'll try these steps tonight when I get home, and report back!

All right, here's something interesting. Before I tried your first step, I remembered that the other night, I left it stuck at the Samsung logo -it was just kind of stuck there, and since the behavior was a little different than I'd seen before (not continuous bootlooping), I thought I'd boot into recovery and wipe. I did, I wiped (factory reset), and rebooted. The tablet booted into the first screen, Accessibility/Wi-Fi, blahblah. This was where it usually rebooted. On a hunch, I bypassed entering in my WiFi key. I then bypassed almost everything else (Samsung account, Google account, etc.), expecting that the tablet would reboot at any moment. But I made it to the front apps page, where it shows you the side-launcher, the Magazine-Flipboard thingie, and whatnot. Wi-Fi still not connected, though. I opened up the app drawer, and scrolled around. Looked really good for a moment. I even took a picture with the camera, and viewed it in Gallery! Feeling brave, I thought, "well, maybe it just needed a couple of minutes before firing up the radio." So I went into settings, and inputted my WiFi key. It connected. And rebooted into its bootloop. (getting so tired of that boot-sound).
Went ahead and flashed the most original stock firmware I could find. As always, flashed successfully. As soon as it booted, I made my way to recovery, and wiped, per your instructions. No luck. Bootloop again.
It's something in the WiFi is what I've come to think as a result of the above. Which I don't entirely understand, as I thought the radio got re-flashed with the firmware.
I'm ready to try flashing a Custom Rom. Can I do that through Odin, or should I try and flash TWRP, and do it through there? Will TWRP flash without a working (bootable) OS?
All right. Thanks for your response!

Try this as a test.
First make a full backup of every partition with twrp including the EFS <<IMPORTANT!
Get it booting again without wifi then root the device and delete the EFS folder or delete it in recovery.
Reboot the device and try and enable wifi.

Got TWRP installed. Won't backup. Fails at 16% (system partition, I think). Just powers down to battery indicator in the middle of the backup. Looks like it backs up the EFS, though, since it's the first one. And when I go into TWRP's Restore option, there's a backup there (though I don't dare try and restore it).
Now I have to figure out a way to get the Custom ROM and GAPPS I downloaded onto the tablet without a reliable boot... It's gotten to the front screen a time or two tonight, but starts looping even when I bypass the WiFi setup.

Entered adb/TWRP interface. Tried to push two files, a Custom ROM file, and a GAPPS file. The ROM failed, with some sort of "Error 7," incompatible data, blahblah... Just out of curiosity, I tried to push the GAPPS file, and that failed after about 6%, and the tablet powered off.
I'm running out of ideas.

copied a custom rom to a USB/OTG stick (thumbdrive), and plugged it in. Fired up TWRP, tried to install. Wouldn't. Wouldn't install GAPPS, either. Looks like the only way it wants to flash anything is through ODIN or KIES.

The Latest...
All right...
I remembered that sometimes the TWRP version mattered. When I installed TRWP last night, I installed the latest and greatest, 3.0.2. Last night after I gave up, I remembered that sometimes, the latest and greatest TWRP doesn't install things perfectly. So, this morning, I downloaded TWRP 2.8.6-ish onto the USB/OTG device, and re-flashed the recovery partition. To be honest, I was surprised that TWRP was even able to flash that (but the TWRP image is only like 9.8 MB, so...)...
Got TWRP 2.8.6.0 flashed, and rebooted into TWRP. Immediately decided to try and re-flash the custom ROM that I'd tried unsuccessfully to flash last night, since the thumbdrive was still plugged in. Resurrection Remix Lollipop. Lined up GAPPS in the queue, as well. The ROM *appeared* to flash better than it had in TWRP 3.0.2, but it was sort of hard to see... GAPPS failed, and I was prepared to watch another round of bootloops. It did bootloop, sort of. The RR splash screen appeared, said that it was installing (or preparing) xx out of XX apps. Then, it rebooted. I figured it was doing its bootloop thing. However, it got to the same screen, "installing xx out of XX apps. Except that XX number had gone down, and the xx number had gone up. It repeated this action about 4 times --the last time I saw it reboot, it was "installing 1 out of 2 apps." And then...?
It booted into the RR lockscreen.
Of course, there were no GAPPS. In fact, there are something like only 20 apps total on the tablet. But it appears somewhat stable at the moment. (See picture).
Afraid to try and connect WiFi, afraid that it'll just bootloop.
Speaking of bootloop. At one point, once we got it booted, my wife hit an option in the Settings. LCD Density, I believe. As soon as she hit it (she literally just placed her finger over the 320 default option), the tablet rebooted. No loop, though. Rebooted straight back to the RR lockscreen.
So I appear to have a somewhat stable OS flashed onto the tablet at the moment. No GAPPS, though. No WiFi.
Anybody have a suggestion on where to go from here? I have my doubts as to whether or not I can even back up this configuration.
Sorry about all the updates. I kind of figured that if *anyone* else ever goes through what I'm going through, they'll have some sense of all the different things that can be tried in resurrecting a bricked/bootlooping device. I appreciate everyone's efforts to date -thank you so much, @Lightn1ng and @ashyx.

All right, because I can't leave well enough alone....
I got WiFi up and working. Tablet still stable and working. Wheeeee.... No GAPPS, though.
Downloaded GAPPS, second-smallest package from opengapps- only 128M (5.1 ARM package). Downloaded it in Android, from the tablet! Tried to flash it in TWRP. Failed, tablet rebooted halfway (not even) through. Now it's bootlooping again...
I should've left well enough alone, and waited for someone. Have tried re-installing Resurrection Remix, but tablet keeps failing to flash. Might have to try and flash a different TWRP. I don't know...

Have you tried another Gapps? Also, is this the WiFi only model or the LTE model we're talking about?

It's the WiFi-only model - SM-T800.
It's kind of weird. I thought it might be some sort of internal memory problem (like the worn Nand pages you mentioned), since almost anything I try to do in TWRP fails (although I was able to flash an entire Custom ROM the one time AND get it booted) -but backing up isn't working, whether it's to internal/external SD. And the fact that I can flash perfectly (subjective term there) well using Odin or Kies tells me that whatever problems the tablet is having, something's getting through.
I'll try a different GAPPS package. Right now, though, TWRP isn't letting me flash hardly anything, and moving files back and forth on this thing is just awful.
AGH - I was so close!

Maybe somebody else with a T800 could backup their entire EMMC using
Code:
dd if=/dev/mmcblk0 of=/sdcard/full_nand_dump.bin
And you take the file on your tablet and do
Code:
dd if=/sdcard/full_nand_dump.bin of=/dev/mmcblk0
And restore YOUR efs folder using TWRP.
THIS IS A DANGEROUS OPERATION AND I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!

@ashyx Any more ideas before I go ahead with my evil world domination plan to recover this device?

I wouldnt carry out any risky operations until a full backup can be made with twrp or you may end up with an unrecoverable device.
If twrp cannot backup the system partition then there is an issue with the partition.
Try backup again and post the recovery log, it may contain some relative information.

I have the same issues and have tried eveything. I was rooted and running the latest Pheonix rom on my sm-t800. Last Wednesday (8-10) I starting getting boot loops out of nowhere, no new apps nothing just a daily driver. I've been through everything on here and have gone back to bone stock but to no avail, the boot loops just keep coming. I can connect to wifi and get things set up but if I try to use anything more than 'light usage' the tab starts its boot loops again and rows fits for about 10 minutes and always different timing on the boot. Sometimes it will make it to the Samsung logo, sometime only to Tab S and sometimes about 10 seconds of usage.. I know this isn't helping much but wanted to let you know there are more of us with the same problem. Will be blab to try anything to help said issue.

Exactly the same issue on my LTE version.
Samsung support just asked me 230€ for a new motherboard.
I refused to repair. I think it is related to nand memory..

Hello I have both the 8.4" and 10.5" I updated the 8.4" to Android 5.02 nothing but boot loops my other is still on 442 and I wont be updating it as its working fine. I have been reading a few posts and the problem was right in front of me all the time I have 2 internet connections 2.4 GHZ and 5.0 GHZ if I connect to the 5.0 GHZ I get boot loops but if I stay on 2.4 GHZ no problems what so ever so I may just install a custom rom and my 10.5 tab and stay clear of the faster internet.

Installed Lineage 14.1, get messages Hello, I've been trying to install Lineage 14.1

Hello,
[Sorry: can't edit title]
I've been trying to install Lineage 14.1 on my Samsung Galaxy Tab Pro (SM-T520), and haven't been successful.
I keep getting the message "Google Services Framework keeps stopping", sometimes alternating with the message "android.process.media has stopped".
I've used the following installation procedure:
1. Starting with the stock Samsung Android v4.4.2, I used Odin v3.1.2, to root the device, by installing
CF-Auto-Root-picassowifi-picassowifixx-smt520.tar.md
2. I used Odin to install picassowifi TWRP v2.8.7.0. I didn't use the latest v3.1.1-0, because it reboots the
device while making Nandroid backups. Available here
https://eu.dl.twrp.me/picassowifi/
3. I copied several versions of Lineage OS amd Gapps (see below) to the device's SD card
4. I used TWRP to wipe the cache/dalvic/data/system each time, using the Wipe->Advanced option
5. I used TWRP to install the Lineage OS amd Gapps as an atomic operation on the device
6. After installation, I rebooted from TWRP:
- without rooting: I get the message "Google Services Framework keeps stopping"
- with rooting, by installing SuperSU: The device enters into a boot loop, displaying the sliding Lineage logo
I followed the same procedure to update my Samsung Galaxy S4 Mini, and it worked flawlessly.
I tried the following Lineage OS versions, available here:
https://download.exynos5420.com/LineageOS-14.1/n2awifi/
lineage-14.1-20170506-UNOFFICIAL-n2awifi.zip
lineage-14.1-20170715-UNOFFICIAL-n2awifi.zip
I also tried the folowing Lineage OS versions, available here:
https://download.lineageos.org/n2awifi
lineage-14.1-20170608-nightly-n2awifi-signed.zip
lineage-14.1-20170713-nightly-n2awifi-signed.zip
I tried the following versions of Gapps, available here (32-bit arm, Android v7.1, stock variant):
http://opengapps.org/?api=7.1&variant=stock
open_gapps-arm-7.1-stock-20170505.ziip
open_gapps-arm-7.1-stock-20170711
I tried several combinations of these 2 packages. With all the combinations I tried, I got the results summarised above.
This post suggests installing Lineage OS alone without Gapps, and then install Webview Implementation, if not installed:
http://www.lineageosrom.com/2017/02/how-to-fix-google-play-services-error.html
When I tried this and reboot, I get the messages "android.process.media" has stopped, followed by the message "clock has stopped". When I click away these messages, and click on next on the Lineage OS screen, the device enters into a boot loop displaying the sliding Lineage logo. This agrees with the Lineage recommendation, that both packages need to be installed at the same time:
https://wiki.lineageos.org/devices/n2awifi/install
Can anyone please help? I really don't want to go back to Android v4.4.2 on my SM-T520.

Hello so to get rid of the error I would suggest downloading samsung kies 1 not 2 or 3 and flashing completely back to stock then try rooting and flashing rom should get rid of system errors and force closes. Kies will ask you for model and serial number. Serial is found on back of the tablet. As another suggestion I would try resurrection remix by cosmox. It is very stable everything works. I just posted a link in that thread with a link to download samsung kies for a 64 bit windows and other relevant files if you need. Let me know if you need any other help. Also closer inspection of your links. I think for sm-t520 u should be using twrp Picassowifi, not n2awifi so idk if that will work or not. Not sure about that part though because they may have made it work on Picasso.

Thanks paintball.
I confirm that I had used picassowifi TWRP. I've edited the original post to indicate this.
I've also tried what you suggested - I reinstalled the original stock Samsung firmware using Odin, and used TWRP to again install Lineage. Same result, still displaying the same Google Service errors.
I'll look at the Resurrection remix.
Paul

paintball,
I've found a solution, that I thought I'd post here in case anyone else has the same problem.
I wiped the cache/dalvic after each step of the installation:
Wipe-> Advanced -> wipe cache / data / dalvic / system
Install -> flash Lineage -> wipe cache/dalvic
Install -> flash Gapps -> wipe cache/dalvic
Reboot -> don't install SuRoot
I got a Music closed error during the first boot, which hasn't appeared since.
Afterwards, I used Odin to install CF-Auto-Root. The device rebooted twice after this step, but now appears to be OK.
A final problem I had was that it couldn't find my wifi SSID. I solved this by setting wifi region to Europe.

I suggested using Samsung kies which I'm positive works, not Odin, but I'm glad you got it fixed.

I'm having a similar issue. Mine differs in the following ways.
I was able to successfully install and run LineageOS with OpenGApps full, but reverted to a nandroid backup because I needed some information from the original install. Since then, I have been unable to get past the initial couple of screens for setting things up--and this with the constant "Google Services Framework keeps stopping" error.
I have tried most of the "fixes" I've found but to no avail. I notice that, (1) when I go to the drop-down menu and setup WiFi, as soon as the device connects to the Internet, I go to the Lineage bootup animation and get stuck there. If I hard boot from there, I can get in up to the point where I connect to the Internet (not just router, but actually get through to the Internet) and (2) I cannot enable Developer options--when I try, no matter how many times I click on the Build number, I get no indication of the options being enabled.
I have tried several permutations of Lineage OS nightlies along with various flavors of OpenGApps, with and without root, wiping cache/dalvik/data/system, wiping only some, wiping none.
I also cannot restore the backup of the running LOS that I had up (I did take a backup before going back to the original setup). When I try, I get the same results as above--as if I had backed-up an un-instantiated setup.
Any thoughts?

Hi Eckster,
I have exactly the same problem on a LG G2 with LOS 14.1. It ran July version perfectly but I didn't make a backup and now I'm stuck. Did you ever manage to fix this?
Thanks,
Kevin

Managed to solve it. I formatted all partitions _including_ data (which means you'll also loose all zips you wanted to install so make sure that adb is working). Then rebooted into the recovery. Installed as usual, worked.

:thumbsup: I was on lineage 14, all was well. I tried an old stock rom NK2, that was fine. I tried to restore lineage backup via twrp, got this problem with the framework crashing. No amount of re-flashing twrp nor lineage, gapps, modem, bootloader, etc nothing worked; always crashed right after boot to lock screen. Finally twrp "format data" - yes. Now lineage boots to welcome, no crash; restore backup - after copying it back to internal - and all is good.
I'm glad it works but why is it needed in this case to remake the filesystem on data - does it work by removing some bad file or does it work by rebuilding the ext4 and security context? this is with latest twrp twrp-3.2.1-0-klte.

Hi,
don't know if you solved it eventually, or maybe helpful for other people with the same problem. I had the same problem, spent 6 days digging around on the internet why the framework keeps stopping and crashing.
I eventually found out that:
- TWRP 3.0.2.0 is WAY more stable than 3.1.1.0 (which never succeeded in installing gapps without crashing)
- Wiping system, data, dalvik recovery and internal storage is not the only thing that needs to be done. You also need to use the 'FORMAT DATA" button (everything will be wiped from your tablet, so, as always, backups )
- After that, install the lineageOS binary, after the installation, wipe dalvik/cache, go back and install the appropriate GApps package, wipe dalvik/cache and reboot
Say whatever you need to whatever deity you prefer and wait for the tablet to boot.
I hope to be of some help to other people having the same problem

Was going crazy trying to figure out why LineageOS was encountering so many ANRs. The first time I flashed Lineage it worked beautifully but every time after that it just went nuts. This fixed it for me, thanks dude!
Note to others who may end up here, after formating data I had to install a stock ROM, then wipe and install Lineage. Lineage wouldn't install due to Updater process ended with ERROR: 7 which was because there was some bit of information that was on the data partition that showed the install script that the phone was actually a Note II. Formating data blows that info away but installing stock puts it back on.

Coming into this thread after a few hours of struggle with an old GS4 I can say that this method instantly worked for me as well.
Thanks!

Thanks for the help to resolve my issue of installation. Do you have a solution for Zoom , where my audio (cannot hear other speakers) and video is missing. Did enable access for Mic, Camera etc in App permission.

Look at this thread: https://forum.xda-developers.com/ga...-t520-unofficial-lineage-14-1-t3538770/page86 -- last two posts

Can only flash CM 11-20150831-SNAPSHOT-XNG3CAO3FN-d2lte

I can flash back to stock via the SkipSoft Unified Android Toolkit, but not matter how far back I go, the only 3rd party ROM that will not get stuck on a never-ending bootscreen after install is CM 11-20150831-SNAPSHOT-XNG3CAO3FN-d2lte. Not even the CM nightlies that came immediately before or after would work once this was installed.
I would like to try something newer if there is a stable Lollipop, Marshmallow, or Nougat ROM you would recommend. I don't use as a phone anymore, so I don't even need cellular data to work.
Thank you very much to anyone that even takes a look at this.

This forum is for the Sprint S3, but I don't recognize your model number. Sprint is SPH-L710
If you do In fact have the Sprint model, I have many ROM suggestions. Including nougat ROMs. Also make sure you have the most up to date TWRP. Don't search d2lte anymore, they are no longer unified LTE builds. Sprint is d2spr, att is d2att, etc.

It is definitely the sprint model. And I don't search for d2lte - I know that was a very short term thing for CM. Nothing else will flash and then boot though. Even tried using d2spr nightlies that were released after the 8/31/2015 d2lte snapshot.
I was using TWRP v3+ already but I used their official app to flash latest version, as per your advice. Now device only boots to download mode.
No worries as this is not my daily driver. I do hope to get it fixed, though.
Am I going to have to use the toolkit to flash stock and try again or is there a way to progress from here?

Wow never seen that from installing TWRP. Do you have the triband model by chance?
I would try Odin back to stock and flash TWRP again. I usually get TWRP right from their site.
Are you wiping data and factory resetting (including internal storage) before trying to boot these ROMs? It is required for the newer ROMs. Octos has a good nougat build. Commotio is pretty solid too. I'm running lineage right now and it's perfect.

That was a first for me too. TWRP has always been fairly easy to install and update.
Not sure if this is the triband but I assume that is more expensive and that it is not the standard model Sprint was pushing, so I doubt it. Is there a way for me to check?
Yes I was wiping data, cache, system and internal storage wit each install. I had an AT&T Samsung Galaxy S3 and an AT&T LG G3 that I did a lot of flashing on, so I am familiar with the basics. I tried flashing lineage and commotio recently with no luck and had to install the final CM11 snapshot again.
Will flash back to stock and will try again. If I recall, the final update is only OTA. Do I need to take it before moving on?
Thanks for your help!

Shouldn't need all updates, but it's not a bad idea. If the model has a "t" on the end then it's a triband. That one can be troublesome.

Sorry for the delay. I had some issues restoring stock with one PC and was too stubborn to try on a different PC until yesterday.
Was able to get stock working, rooted and I installed TWRP 2.7.x and then updated to the latest (3.1.x). I then wiped all partitions from TWRP and sideload installed latest Commotio and opengapps. Same issue - stuck on the boot screen (animated water).
Anything left to try? Confirmed it is not the triband. Thanks again.
UPDATE: just tested with latest CarbonROM. Issue persists

I've been stuck on boot animation on a few fresh installs of ROMs. If I let it sit there for 5 mins or so then hold power until it reboots, it usually boots up. Where KitKat ROMs used to say building dalvik cache, or whatever the particular ROM had, newer nougat ROMs do not. The boot animation plays while it establishes art caches. It can take awhile on a fresh install.

Tried flashing Commotio again and held down power to reboot after about 5min on boot screen. Waited over 10 mins the second time and still no luck. Just reboot again and will give it until the battery dies. Let me know if you have any other suggestions. Thanks again.
UPDATE: Tried with latest CarbonROM and latest LineageOS builds as well. None will boot. Old CM11 snapshot build still installs and boots without issue.

Have you formatted data? Switching between KitKat and nougat you have to wipe internal storage.
I would "format data" not just wipe (in case of any encryption) and also do a factory reset in recovery.

Yes - I have wiped everything, including internal storage and used the "format data" option. I have tried ADB sideloading each of the ROMs mentioned with everything wiped. I've also tried removing the external SD card, copying the ROMs to it from a PC, reinserting into the phone and attempting install that way. Still, no luck.

Wow, that is thorough. Maybe make sure non of your ROM or gapps packages are corrupt (check md5 or sha1, etc.)
What gapps are you using? I usually use open gapps for 7.1x arm, mini or micro. Beans gapps also work well. Just make sure they are for 7.1.
Maybe try to boot the ROM without gapps ( just a shot in the dark). Are you flashing any other mods with it? I think Commotio comes rooted with magisk.

I have tried with 7.0 and 7.1 opengapps arm pico but I haven't been doing so during troubleshooting so as to isolate the issue. I tried once with Commotio and once with CarbonROM in case they needed it for some reason, but since no luck, I figure I'll wait to flash gapps once I get a successful boot.
I downloaded all ROMs with Free Download Manager, which does a pretty good job at maintaining file integrity and working through connection hangups, but I will try downloading with Firefox by itself and verifying the checksums to be sure. Will get back to you - thanks again.

I downloaded Commotio and CarbonROM again and verified the md5s. All good there. I wiped everything except OTG again and tried installing from the SD card (formatted as well before the ROMs were copied over). Still stuck on boot animations. I attempt a power button restart after about 10mins a couple times then I let it sit for 30+min without any success.
Hope we haven't reached the end of the line yet. I'm very curious about what could be causing this.

Well I'm stumped. Have you tried LineageOS? These ROMs are all based on Lineage. Sometimes there is a bad nightly that refuses to clean flash and it spreads to all other ROMs. Maybe try a build from a few weeks back (or even a month if you can find one) and if that boots then you can update to the newest with a dirty flash.
I see you did try LineageOS and tried some older builds.
Well, I can maybe make a backup of a fresh install after first boot and upload it for you. You can try restoring it on your phone and see if it boots. You would have to have the folders created on your phone (or external sd card). Like
"TWRP/backups/* your phones serial number*/*name of backup*"
Obviously without the quotes and stars and with your devices actual serial number. Only thing is, backups are pretty big files.

I did not try Lineage or Vanir again like I did Commotio and CarbonROM to verify the md5s. I will try them and some older builds of each.
I sincerely appreciate the offer. I would certainly be willing to download a large backup if you would be willing to take the time to clean install and upload. Let me try the remaining steps you listed first, though. Don't want you to have to spend time doing all that if we can get it working another way.
Thanks again. Will keep you posted!

Downloaded, verified and copied all these files to a freshly formatted SD card, inserted into the phone, booted TWRP 3.1.1-0 and wiped Dalvik / ART Cache, System, Data, Internal Storage, and Cache before each install:

Only ol' reliable (CM 11 d2lte 8/31/15 snapshot) will boot.
This phone was fully updated with all OTA updates before I ever attempted to root, install a custom recovery or ROM about a year or so ago. I remember having issues even then, not being able to get any CM version to boot except for that one, which was already old at the time.
For kicks, I tried dirty flashing the CM 12 d2spr 11/17/15 snapshot over ol' reliable in hopes that it would boot and I would be able to dirty flash all the way to an Oreo build. It didn't work.
Also, each time I have flashed back to stock to retry, I have used the *NJ2 build.
Not sure if any of that matters, but trying to think of anything that may help pinpoint the issue.
If no other ideas, I would like to take you up on your offer and try a TWRP backup of a fresh install of any recent, stable ROM from you device, if you would be so kind to upload.
Thanks again for the help. For what it is worth, it has been fun troubleshooting this. I'm too afraid to do anything with my S8, but miss the fun I had with my AT&T S3 (never had any issues with custom ROMs, but I also didn't take all the OTA updates) and my AT&T LG G3, which got blue screen disease.

Mine is on nj2 as well. Mine takes a little while to boot, but not hours lol.
I'll see if I can backup a fresh build today. I won't be able to upload until tomorrow (no wifi at home right now). I can likely upload when I get to work, I get there pretty early. I'll pm you a link when it's done.
Really don't know why that's the only thing that will boot for you. It has been fun trying to get it to though.
I'll flash LineageOS (most recent) with open gapps mini. I'll boot to the setup wizard and then make a backup. Hope this works, mostly cause I'm kinda out of ideas, lol.

Thank you. No rush - whenever you have time.
I don't get it either. I waited a long time to post about it because I assumed there was something simple I was overlooking that I would eventually figure out. Not sure this will work if nothing else has, but I can't wait to give it a shot.

[HELP] WiFi keeps disconnecting and reconnecting

My XT1795 is on stock 8.1 with unlocked BL, TWRP and magisk (I haven't installed any modules though). I am facing this weird issue since an year, the WiFi randomly keeps disconnecting and reconnecting automatically every 10 to 15 mins. I am sure that it has nothing to do with my WiFi router as I face the same issue when I am connected to mobile hotspots or any public or private network. I tried resetting the wifi and network settings, restored the device quite a few times, and also reflashed the stock rom but the problem still exists. The most recently that I reflashed the stock rom was a month ago, i didn't face any issue for the first 15 days but now it's back again.
Can someone please help me?

Try using a different kernel. But make sure that stock 8.1 is supported

You have root right? Try taking some logs until WiFi crashes. Then wait a couple of seconds before stopping log recording. I will try to look into it.

Please have a look at the logcat, this morning while generating this log the wifi network ([email protected]) disconnected and reconnected atleast 3 times. Even after the reconnection, most of times I am not able to access the internet, I have enable airplane mode, then enable the wifi again or reboot the device. I am sure there is no problem with my router because, I face the same issue when ever I connect to any network be it a mobile hotspot or railway public network.

As far as I have seen this is what's concerning:
1
E/WifiVendorHal( 2001): stopRssiMonitoring(l.2156) failed {.code = ERROR_NOT_AVAILABLE, .description = }
Some vendor realted stuff is just gone.
2
W/WifiConfigManager( 2001): Looking up network with invalid networkId -1
The NetworkID (probably which decides which network it tries to connect to) is ****ed
3
E/wpa_supplicant( 3589): wpa_driver_nl80211_driver_cmd: failed to set RXFILTER option I/QCNEJ/CndHalConnector( 2569): -> SND notifyRatConnectionStatusChanged(rat = 1, DISCONNECTED)
Yeah I think drivers are just ****ed
I would personally suggest 2 things
1. Install lineage 15.1
2. Re-install stock
Alternatively to 2:
Factory reset, could fail though due to magisk and force-encrypt

This problem started after I unbricked my phone few months ago. I flashed an older version of bootloader on my XT1795 which lead to a complete breakdown, the phone was unable to boot, I had to flash mmcblk0.tar and this rom on a 32GB sd card and booted from it so as to flash a new stock rom on the int storage. After all those efforts the phone booted up but I started having this WiFi issue.
I'll try installing lineage OS because , I have tried reinstalling stock 2 times and even factory reset-ed the device. Thanks alot for responding.
Edit : I have flashed the LineageOS 15.1, will update if the problem persists.

The wifi drops are more severe on lineage 15.1. Most of the times there's no internet access even while wifi is connected. Please have a look at the new logcat file.

I am being forced now to roll back to the stock rom from twrp backup.

When it is like that even on lineage, try downgrading to nougat and see if the error persists, I also have this problem now btw... I'm on Android 9 though
If the error doesn't persist, upgrade back to Oreo. And see if it's fixed, if not, then I'll have to try around a little bit by myself
Also, me being on Android P with Radium, it isn't really a kernel issue.
I just cant decide what it is,
Also, don't use the "stable" build advertised pretty recently in jarl's lineage 16 thread, it isn't stable
(Bruh)
I will try downgrading to Oreo and see if the error persists for me.

1.
Now I flashed stock 8.1 (fresh flash) on the lineage 15.1. The wifi problem is still there. Like you said, the last way could be downgrading to Android Nougat but I am scared it could hard brick the device. Why I am saying this is I did a downgrade 7-8 months ago, which bricked the phone and led me to Blank Flash 7.1 srock rom to finally make it boot, it was then this wifi issues started. It was a disaster, later I came to know that downgrading bootloader from from a new version of rom to an older version will mostly end up in dead devices. :highfive:
2.
So do you still think I need try downgrading once again ?
3.
I am fed of this phone now, I was planning to get a new one but everything in India is locked down till 15th April. I only have this flashing time till that date, from 16th (could be even 10th) I have to attend office.

We have one last resort,
G. S. I
If that doesn't work, then it's due to isp's being overloaded from all the streaming which is happening.
For me, it started when testing an "stable" (*cough cough* it isn't *cough cough*)
Lineage update
Install latest , non wiktor build of lineage 16.0 builddate
20200208
Or the gsi "optimized" 2019070X build
And then installing a pie (or Q) GSI of choice

Please try to run this command in terminal emulator, while wifi is on.
Code:
su
killall wpa_supplicant
This will kill all the active connections and reconnect to current network, I read on linux foums that this fixed the wifi issue at least temporarily.

Okay okay. I got the.. ahem... "Fix" for the issue.
Basically, when reinstalling almost everything (except firmware)
It just fixed itself? I dont know how it just did.
Try reinstalling Lineage 15.1 or 16 (jarl's builds, wiktors cause more problems aka Lineage 16.0 v0.16 instead of 0.17)
And then installing a GSI of choice. If you didnt look that up yet, basically, you know how on a PC, no matter the hardware, you can install windows on it without device specific ****? Yeah that's project treble, allowing installation of updates and ROMs using .img files.
Luckily, our Lineage 16.0 builds (and only those) have full support for treble, so, just download a rom of choice, RR for example, extract it using an application like RAR and then wipe ONLY
/System & /Data NOT FORMAT
Wipe>advanced wipe> select system and data
This won't erase Internal storage just uninstall all apps and stuff
And then head to where you extracted the .img file and select "flash zip" in the bottom right corner
It should now switch to: "install Image"
And the extracted file should show up.
Select it, select "system image" and flash
Don't worry about it saying: " NO OS INSTALLED" And blah blah blah. The phone will take care of it, unless it crashes, then the rom isn't compatible with our specific device.

If the launcher for example is lagging, try adding this line
Sys.use.fifo_ui=1
Into build.prop and rebooting, maybe that makes it better
