Nope is a bug
[Galaxy Tab 4 Android Development] BeeJ1109:
Hi DJABHipHop, Matteo0026

I have a working version of TWRP V3.4.0-0, working great for sometime, on my Galaxy S4 mini GT-I9195.

Built by arco68, suggest you check it out. Also allows all 8 partitions to be Backup & Restored.

Allowing to select any option you require.

So I suggest you look in XDA and github. For source that you may help fix your versions for Tab 4 8.0 and 10.1

[ROM][I9190/I9192/I9195/L520/L520]UNOFFICIAL[10.0.0] LineageOS 17.1 for S4 Mini by arco68.

Recovery (TWRP):

GT-I9195: http://www.mediafile.com/file/uatfq62gkjw2ao9/twrp-3.4.0-0-serranoltexx.img/file file

uploaded July 1, 2020 at 11.30 pm. So is a pretty recent version.

Notes extracted from arco68 post.

TWRP Build . It needed to changed to support the new system-as-root in Android 10. The official TWRP builds doesn't have it yet.

If you are doing of 17.1 with TWRP, and want to restore one of these backups, you need to flash this right after restoring, or otherwise the boot will hang: http://www.mediafire.com/file/a454nnpp817afbr/fix_rootfs_label.zip/file

Hope that helps to fix the present issues reported by users so far.

Cheers BJ

Hi guys, love the ROM, runs smooth as butter. I was wondering if it would be possible to add the multiple users feature to the ROM so I could setup restrictive access for my kids ? Thanks !

Thanks for the info. I tried to download http://www.mediafire.com/file/a454nn...label.zip/file but this file is not found. Can you please help?

What TWRP did you use?

---------- Post added at 06:49 PM ---------- Previous post was at 06:38 PM ----------

What version of TWRP did you use? could you share a link? i installed everything successfully but got a boot error mentioning "Set Warrenty Bit: Kernel" and the device gets stuck

What version of TWRP did you use? could you share a link? i installed everything successfully but got a boot error mentioning "Set Warrenty Bit: Kernel" and the device gets stuck
[Galaxy Tab 4 Android Development] matteo0026:
That is a warning and comes out if bootloader feels that isn't booting official software (custom ROM or recovery).
[Galaxy Tab 4 Android Development] nulp12:
what can i do to pass this message? the device does not boot when this message appears
[Galaxy Tab 4 Android Development] matteo0026:
It's different. Device doesn't boot because ROM doesn't boot. Try my lineage 16 and see if it boots or not. That is just a warning, ignore it!
[Galaxy Tab 4 Android Development] nulp12:
I have tried with your LineageOS 16 from this post https://xdaforums.com/tab-4/orig-development/rom-lineageos-16-0-tab-4-8-0-10-1-t4032901 (TWRP 3.4.0-0, lineage-16.0-20200712-UNOFFICIAL-matisselte.zip and OpenGapps ARM 9.0 Pico)

and i get in the same situation. stuck in the Samsung Galaxy Tab4 Screen and not booting the ROM. After a while it boots back into recovery mode.

Did i have to do something before flashing TWRP recovery? or am I doing something wrong?
[Galaxy Tab 4 Android Development] matteo0026:
Probably, you have a too old firmware preinstalled in your tab 4. So, install latest 5.0.2 firmware and come back to install these ROMs. And the builds for matisselte I remember you that are just for T535, and not T537 variants (which are USA ones, and I don't support them)
[Galaxy Tab 4 Android Development] Digger_m:
Are you installing with the zip files stored on sd card or from internal memory. If so move the files to internal memory it may fix it.
[Galaxy Tab 4 Android Development] matteo0026:
Absolutely no. You can have the zip files wherever you want. Internal memory, SD card or USB OTG. No problems at all. I repeat, the problem is coming from your tablet. So, before flashing something else, go to flash latest stock firmware and then come back. I don't want to hear other gripes. Do you see some other users that comply about my ROM that is not booting? No... Then... Troubleshooting is easy, in this case.
[Galaxy Tab 4 Android Development] Digger_m:
In my experience some roms haven't booted when installed from SD card but will boot when installed from internal storage . It's an observation worth trying
[Galaxy Tab 4 Android Development] nulp12:
I upgraded to 5.0.2 and it works!!! Thank you so much for the help
[Galaxy Tab 4 Android Development] mrk2815:
if most dont follow instructions as the developers post and not cut corner, then they will run into issues and end up blaming rom or development.i strongly erge, first mmake sure the stock firmware is up to date, take a back up and then begin tinkering with roms, that has been my experience and i have been roming since 2010. . AT least that has been my experience.also i have always installed from internal storage .have had two samsung devices, the tab 4 millit wifi, and a note 4, that has been my experience.everything else i have internal storage only and not external storage like my nexus, pixel, and one plus devices.
[Galaxy Tab 4 Android Development] DJABHipHop:

- Rom now has Face Unlock
[Galaxy Tab 4 Android Development] mrk2815:
dj, with the new builds do we need to use twrp 3.3.1 or twrp 3.4. to do a clean flash.just wondering.

---------- Post added at 02:26 PM ---------- Previous post was at 01:33 PM ----------

has anyone else installed the august build. what twpr did you use and what gapps. as i still get a bootloop with a clean install with twrp 3.3.1 and the latest august build. if i flash the june build no issues with twrp 3.3.1 but as soon as i do a clean install of the august build in twrp 3.3.1 then the bootloop occurs.so don't know what to try or any suggestions welcomed.
[Galaxy Tab 4 Android Development] DJABHipHop:
Lasted TWRP GAPPS NANO
[Galaxy Tab 4 Android Development] DJABHipHop:
here what I do when it does not boot is I

- First inupdate TWRP & see if that fixes thr problem if not.

- Then do a backup System, Data, Boot & Recovery ...

- Then whips system, caches, dalvick cache, date.

- Then formatted the device & reboot back into TWRP.

- Then flash the update, flash gapps & magisk by add each zip to the cue starting with the ROM, then the gapps if you use them, then magisk if you need or use root, the may very depending on your needs, I don’t use root since I can always add the feature in the next update, make sure to whip the cache after flashing all the zips you use, as for whZ=at version of gapps I recommend to use nano not micro or pisco as nano no to blozted & not to light.

- Then restore your data the reboot back.

into the system if it boots.

- Then reboot back into recovery & do a full backup including the the recovery portions, Efs, ETC...

- Then reboot bacck in system & enjoy you day.

Latest build is under investigation on why it doesn't boot on Telegram group. I really can't try to make los17.1, otherwise I won't support los16...
[Galaxy Tab 4 Android Development] brewer75:
I couldn't flash the new August milletwifi build with the 3.4.0-0 or 3.4.0-1 TWRP because it didn't recognize my tablet as being a milletwifi, no problem with the 3.3.0-0 TWRP. Matteo suggested some file modifications but I am not experienced with the terminal and I couldn't get the file to save. So, I'll continue to use the older TWRP to flash for the time being. Also, I noticed the milletwifi build doesn't appear to have the face unlock AND when the tab is plugged into my computer, the pull down screen that allows switching between charging, file sharing, etc. is drawn over my home page instead of having its own clean screen. Otherwise, all is good!
[Galaxy Tab 4 Android Development] DJABHipHop:
Face unlock is there but you need to chage a build prop ATM to make it work
[Galaxy Tab 4 Android Development] mrk2815:
dj, i updated the twrp 3.4. today. now having issues installing rom.i get this error that error installing compatible milite / millet wifi and erro number 7 and it aborts.i did this a few times.so i don't know what else to try to get around this issue resolved. .
[Galaxy Tab 4 Android Development] DJABHipHop:
That's simple just remove the security check in the zip file
[Galaxy Tab 4 Android Development] mrk2815:
how do i remove the security check in teh zip file. I am flashing the stuff through the open command line script through my pcT that's how i have been alwasy doing it and that why i feel confforable in tthat form.
[Galaxy Tab 4 Android Development] matteo0026:
Can you share me from TWRP 3.4.0 (-0/-1, no difference) these 2 things? Go to terminal emulator and type these 2 commands to check if properties are loaded correctly:

getprop ro.product.model
getprop ro.product.device
[Galaxy Tab 4 Android Development] Duffy22:
Hej DJ. Thanks for not giving up.

I tried the rom 20200803 for matisse wifi, but unfortunately it doesn't boot. Same as the both roms before (btw. they are deleted on androidfilehost?).

The last working one was the 20200628.

I tried your installation procedure from DJ in post #334 without the backup/restore, because I just want to have a working rom from scratch and it still doesn' work for me.

The only step in the instructions that I missed, because I didn't know what to do is:

- Then formatted the device & reboot back into TWRP.

How to format the device???

What I did:

1) tried to install the new rom over the running one (20200628) + whipe dalvic cache.

Result: booting to the 5 dots for a few minutes, then automatically booting to recovery (TWRP 3.3.0.0)

2) From recovery updated to TWRP to 3.4.0.1 + Try again to boot to system

Result: booting to the 5 dots for a few minutes, then automatically booting to recovery

3) In TWRP use wipe/ Advanced from menu and wiped

- Dalvic/ ART Cache

- System

- Data

- internal Storage

- Cache

3.1) Installed the rom 20200803

3.2) Installed OpenGapps Nano 20200805

3.3) wiped cache

3.4) Boot to system

Result: booting to the 5 dots for a few minutes, then automatically booting to recovery

I doubt and I think that I missed a step in order to get the rom working. But which?

System: Matsissewifi TM-530, Lineage17.1 20200803, original stock rom was 5.0.2. ,TWRP 3.4.0.1, open GApps 20200805 nano and nothing more

Samsung Galaxy Tab 4 8.0 (T330NU) also not booting, just looping back to the recovery.

I'm clean flashing Lightning Fast ROM along with OpenGapps Nano on TWRP 3.4.0-2.

The last version of the ROM that booted successfully was 20200628.
[Galaxy Tab 4 Android Development] Digger_m:
I thought I would try installing with a total clean flashed the latest july version with nano gapps, twrp 3.4 and it failed to boot. Also It wouldn't install from SD card. On my sm t530. Back to the June version.
[Galaxy Tab 4 Android Development] brewer75:
Regarding the most recent 17.1 build and TWRP, my SM-T330NU is booting properly and it is functional and stable. I've been using these ROM's for several months and have had a few problems flashing, rooting, and booting over that time. In each case, DJABHiphop and Matteo have worked through the problems and the results are a very functional ROM and recovery. It remains a mystery why some tab 4's have more problems than others but I can only say that I started this process by going back to the last official Samsung firmware and using ODIN to move on from there so that I could utilize the current builds and update them with TWRP as new builds become available.
[Galaxy Tab 4 Android Development] Karbohydrates:
Thanks for your insight!

I've since restored my Tab 4 back to the June 28th update and it'll do the job for the time being, since it is mainly used as a multimedia device. I have no problem waiting for a potential fix.

I know DJABHipHop has been asking around in the Telegram group, and at least a few people, including you, have came forward saying that it works fine. I guess it truly is a one off situation.
[Galaxy Tab 4 Android Development] Karbohydrates:
Looks like DJABHipHop has narrowed down what the issue was for the August 3rd build. The issue was the Trebuchet Launcher. Hopefully soon DJABHipHop will release an update that won't require you to do this, but for the time being this is the workaround.

NOTE: Since the method involves deleting the default launcher, your Recent Apps screen will not work.

Here's what I did to get it working, and huge thanks to DJABHipHip.

1. Flash lightning.17.1.20200803_UNOFFICIAL_milletwifi_Unsweetened_XDA_BUILD along with OpenGapps and Magisk if you need it

2. Go to Mount then check System

3. Plug in your tablet to your computer and open ADB and test if it's connected by typing in

adb devices

4. If it is connected and it says "recovery", type in

adb shell rm -fr system/system/product/priv-app/TrebuchetQuickStep/

5. Check if the "TrebuchetQuickStep" folder is still there by typing in

adb shell ls -l system/system/product/priv-app/

6. If it is deleted, type in

adb reboot

Once you boot in, fill in your Google information or get past the setup and then you'll see a "Tablet is starting" screen, this screen will never load because you've deleted Trebuchet.

Swipe down twice from the top of the screen and then press the Settings icon, go to Apps & notification then go to "See all 21 apps", find Files and then Open, navigate to Downloads and install an APK of a launcher of your choice. I used Lawnchair.

Here's my SM-T330NU booted up on 20200803:
[Galaxy Tab 4 Android Development] mrk2815:
will just wait for the fix to be upload by dj, to test since the weekend is wwhen i test his sort of stuff when i have some time.
[Galaxy Tab 4 Android Development] DJABHipHop:
New updating now boots 100% new feature is face unlock
[Galaxy Tab 4 Android Development] Digger_m:
Just updates to the latest booted up 1st try. Thank you DJ.
[Galaxy Tab 4 Android Development] Duffy22:
Works fine now! No BootLoops anymore! Thanks DJABHipHop!
[Galaxy Tab 4 Android Development] Karbohydrates:
Anyone else clean flashing the ROM on SM-T330NU and having trouble getting past the setup?

I'm specifically having issues passing the "Choose screen lock" screen. When picking any option, I'm able to apply the primary security, but face unlock will not work. When it asks for permission to use the camera, I allow it to take pictures, the camera just stays black and the face unlock setup fails saying "Something went wrong", pressing "Try Again" just keeps telling me "Something went wrong" with the circle staying black. I cannot seem to pass this screen even on my second attempt to clean flash because there is no security option for "None".

As far as I know, the front camera works fine.
[Galaxy Tab 4 Android Development] Digger_m:
Did you try skipping that part of the install then adding it after the install is compleat?
[Galaxy Tab 4 Android Development] Karbohydrates:
O_O

---------- Post added at 01:00 PM ---------- Previous post was at 12:50 PM ----------

I'm afraid it doesn't let you skip that part. There is no option for you to not enter a security option, it will force you to pick and loop you back to the face unlock setup once it fails. Pressing the back button just returns you back to the Google account setup, and makes you enter the PIN you set, only to make you setup face unlock again, pressing "Try Again" just makes me set it up again, only to fail again.

I've since flashed 20200628, ran it through the Android setup and flashed 20200810 on top, seems to work fine. I haven't tried face unlock on it yet, neither camera apps work, so I'm guessing it'll keep failing. Other than that, solid update.
[Galaxy Tab 4 Android Development] mrk2815:
dj, question if the camera is not so great , then how in the hell are you supposed to use face unlock to unlock the dam thing.just wondering.

---------- Post added at 09:17 PM ---------- Previous post was at 09:13 PM ----------

there should be a way to bby pass and give hte use hte opiton for non so theeen if they want then they cna do this later. especially why in the hell do you built in a feature that there is no work around fo and why no none feature to get aroudn tehat aspecto set up Just a bad choice iin design choice . That's why i am sticking with the other lineage rom as that one is better and the wifi does not drop unlike this one where wifi constantly drops no matter what.
[Galaxy Tab 4 Android Development] Digger_m:
Since I use my sm_t530 mainly at night in bed . The low light has pissed of the face unlock and it's suspended its self just thought I'd mention it. It's no problem for me as I keep my password simply.
[Galaxy Tab 4 Android Development] d_tshudy:
thank you
[Galaxy Tab 4 Android Development] Digger_m:
Well that's an oversight and not giving you the choice not to lock your device is wrong I think.

Samsung Galaxy Tab4 SM-T535 compatibility

Hello everyone! :)

I own a Samsung Galaxy tab4 with the exact model number SM-T535. Is this Android 10 software compatible with my Samsung SM-T535?

I have never before installed the firmware on my Android device myself and this is my first time. So does the first post in this forum thread have all the programs I need to install this firmware?

Would anyone have a YouTube video for me showing this firmware installation?

Does the first post in this forum thread have all the software I need to install the firmware on my Samsung Galaxy Tab4 SM-T535 Android tablet? :)

Thanks! :)
[Galaxy Tab 4 Android Development] Digger_m:
Make sure you have read the forums on installing the custom recovery that's the scary part in doing a custom rom / operating system I think. once the custom recovery program is installed your half way there. the TWRP ( Team windows recovery program )custom recovery part must be flashed with odin 1st on samsung devises . TWRP is the gate way to installing what ever custom rom is out there for many devises.

So no you will need to install TWRP using odin via PC & usb cable.

then get the correct Gapp.zip from https://opengapps.org ( platform arm , android 10 , pico or nano ( relates to the amount of google apps in the bundle pico being the bare minimum to get play store )

hope that helps you. i think once you do a custom rom you do get the desire to do more devises as you have more control over what goes on.
[Galaxy Tab 4 Android Development] BeeJ1109:
Hi Matteo,

Just trying your latest LOS 16 version released 08082020.

I realise that the correct thread to post comments for an earlier build, but it appears as discontinued in LFR 16, with last post back in June 9,

So I thought better to post in the Latest version.

As the builds are by same Developers, there may be same issues in LFR 17.1.

Next I plan to trial the later ROM, next.

I found a few issues. (LOS 16)

1. WiFi connection to internet and using a app Speedtest.net.

Being using this test on all my devices, normally Download speeds is 45-48 Mb/s.

Upload speeds 18-19 Mb/s. on T330 Stock ROM.

On your LOS 16 Download mostly stable, peaking at 35-52Mb/s. Upload 16-18 Mb/s. Modem partition not updated. Will compare settings. Noted that you found Vfat instead mmc. in TWRP.

2. Front and Rear Camera Black. Not working.

3. Need a better Keyboard. takes up half the screen. Standard Samsung keyboard more functions. This ASOP on phones is OK, but on 8" Tab not practical.

How to replace and use Stock Android 9 Samsung Keyboard. ???.

4. Detection of Smart Folio Front Cover Opening or Closing Sensing that will be Turning ON or OFF Screen to save battery power drain. Worked on Stock 5.1.1 Not working in LOS ROM.

5. Charger connected whilst OFFLINE (OFF) turns Tab ON and Boots up. - Fix coming.

LOS ROM Info. Charging MAX @ 850mA, same as Stock

6. I Have setup ExtSDCard Write Access. Transferring files works with most applications, with T330 Root Access enabled, for Apps that is required. As well as , enable Write setting in Developer options.

Problem is Moving Apps Data from Internal memory to ExtSD card.

This function works on Stock ROMs on NonRooted Samsung Phones S8 & Tablets T835, T330.

on Android 8, 9 & 10.

Problem is I need access to Root directory, without having to ROOT the Device.

Need ADB commands to extract files to compare. ANY IDEAS would be appreciated.

But on Magisk Rooted Custom ROMs RR 7.1.2(i9305), LOS 9, 10 (i9195, T330), LFR 9, 10. (T330). Not working, still experimenting.

Original fix from Android 4.4 & 5.1 was to add extra line in External Storage to enable Media

R/W access, in Root/system/etc/permissions/permission.xml file.

Android 6 onwards introduced, using "App2SD" App Creates an extra partition in ext4 format on ExtSD card. or Create a media R/W Directory to store apps data on ExtSD Card.

All these fixes on Custom ROMs fail, but after Android 8 thru to 10 work perfectly on ALL Devices, using Stock ROM installed from Factory builds, without ROOT ACCESS.

So Google have solved the issue, whereas up to now, Custom ROM builds have failed to fix.

Must be some Secret Hidden Code in Stock ROM build.

,

.That's my Observations

Cheers
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Before all that, if you haven't done so, is to download samsung device drivers snd odin in windows. You need to read forum articles on every step you take to know what problems you could get through the process. Don't hesitate to ask more questions about anything. That's how you'll learn to flash cistom roms through TWRP recovety.
[Galaxy Tab 4 Android Development] matteo0026:
Let's answer to these questions...

- Wi-Fi connection should be ok. I don't want to work for djab, so ask him to wake up if something doesn't work here on LFR17.1 and works in LOS16...

- Either front and back camera are dark? Are you sure? I know that back camera is dark and okay, but not the front one... Give me a logcat while you open front camera then, if you are really sure that your front camera is dark and with stock ROM works well.

- About keyboard, try to search something on XDA. On custom ROMs, I won't put other keyboards. I think LOS16 should be compiled always without re-touching it later to add/remove some other stuff

- About book cover with the magnet, I investigated 2 weeks ago and I saw the magnetic sensor is too few sensitive since with a bigger magnet it triggers.

- Offline charging is a known issue, let's jump that... I have to investigate better

- I don't advice to move apps to microSD. Just enjoy apps on that 16 GB of storage you have in internal memory...
[Galaxy Tab 4 Android Development] appye:
Hi everyone,

It has been a while since I flashed a rom, but I am sure I can find some twrp instructions somewhere ... I am currently running stock 5.0.2 on a Galaxy Tab 4 10.1 (sm-t530nu), which I gather is a good thing ...

Is there a stable build of this rom that would generally be preferred, or just flash the latest? I am seeing issues with getting it through the initial setup screens ... I don't require bleeding edge, and don't plan on continually updating to the latest and greatest unless it fixes something I care about. I will probably check in once in a while to see what changes have been made, etc.

I notice that the OP says that magisk does not work, but I see others on this thread saying it works for them. Is the OP just outdated? It would be nice to know I can root if I want to.

Also, I is matteo0026 or DJABHipHop the developer and/or maintainer? Just curious, as I noticed how the posts above were addressed.
