Flashed recovery.img on top of existing version of TWRP and got stuck in a bootloop with no recovery. I can get into download mode but odin refuses to setup a connection on two different pcs with many different cables. Anything I can try?

After using for several days here are my thoughts:

I am suprised to see this rom is smooth on this old device which was released close to a decade back. Some parts of the OS did have hicups but most of it was very smooth. I have not tested gaming for obvious reasons, but for a streaming and checking social media this OS is good enough for that purpose.

The battery is excellent, totally wasnt expecting this!

I am glad the rotation works in this OS, my previous rom was the Android 6 ROM which had broken rotation support.

Not everything is perfect about this ROM and yes I did notice some parts where the OS would'nt respond.

Every now and then the OS runs out of memory causing the device to crash and restart. totally expected from a device like this but I hope someone has a way to handle memory more efficiently.

Mobile data sometimes crashes the signal bars are there but like the tablet wouldnt connect to a network like LTE, 3G. (Keep in mind only happened to me once, quick restart fixed it)

Those are some of the noticable stuff i found using this ROM, but end of the day thank you so much for the dev who made this! Your work contributes alot for the people still using this old device.

Thank you html6405 !

Thanks for your feedback,
what we could try next is to configure this devices as a low ram device, but side effects would be:

no multiuser support
no picture in picture support

is it just on my unit that videos (for instance on New Pipe) 720p and above are hacking a lot?
Hmm I don't know, but it could depend on the video format the app uses.
If the device need's to software decode, it will run less smooth as it would via hardware decoding.
Weren't there apps that can help make a part of an extern sd card work as ram?
I guess you mean swap, this is already integrated. (it's not good to keep much data in swap, because our internal memory is really slow)

Any chance there will be a non LTE version of this ROM uploaded at some point (T530NU)?

Thank you!

It exists since more than one year...

Hi,

here you can find my LineageOS 16.0 for the Samsung Galaxy Tab 4 7.0.
At first I want to thank @spookcity138 for your work on the kminilte,
I've reused some things here from you.
For sure thanks to everyone else who ever worked on the Exynos3470.

I'm working hard to provide you a stable version soon.

Here you can see what's working / not working so far:

  • Audio
  • Bluetooth
  • Boot
  • Cameras
  • Graphics
  • GPS, not sure if completely
  • Mobile data
  • OTA Updates
  • RIL
  • Sensor
  • Tethering via USB, WIFI and Bluetooth
  • USB
  • Video playback (HW/SW)
  • Wifi
  • Maybe something



If you are going to use Gapps,
I recommend to use the pico package!
https://opengapps.org/
For the others, you can use microG if you want, I've enabled signature spoofing.


Do you like my work?
Than you can simply hit the thanks button and consider to spend me a coffee or a beer,
I'm doing this in my free time and it also costs a lot of money to buy hardware.

You could use a gps.conf from https://app.box.com/s/w57s1v1n3hie7l5lk28i for your location and replace /system/etc/gps.conf.
Or you try GPS Server Optimizer app for a faster 3D fix.
For both methods you need root rights.

    Dear html6405
    Thank you for providing this ROM for our Tab 4 7.0...
    It's really a long time that no modern ROM appear for this model...
    (My last Android version is 6.0 for this Tablet....Q_Q)
    This rom works fine on my T235y, Just some slow reply in operation due to Low RAM and Slow SOC...
    Would be very appreciate if you keep updating this ROM.....^_^

    Will gladly try your ROM but i will have to wait untill the weekend..
    I'm testing it since yesterday and I have to say I'm really satisfied,
    as soon as I have fixed the camera's, mobile data and the acceleration sensor, this ROM should be great.

    Btw, did you have any use of the old marshmallow for it?
    Nope :),
    never tried this, you can set the font size as it should be in LOS, just try it if it's big enough ;).

    Update 19.05.2021:
    • Programmed new open source HAL for the acceleration sensor, screen rotation is working now.
