Does this ROM have OTA updates?
[Galaxy Tab 4 Android Development] crazydrive22:
Nope, it's unofficial.
[Galaxy Tab 4 Android Development] SteinbeckFan:
This time I did exactly your procedure for performing a dirty ROM flash. And it WORKED! :) One trend I've noticed is that the longer people wait to download a file from AFH, the greater the chance no mirrors found error. Your TWRP posting from June 23 no longer works. But the CypherOS from today July 15 works. My advice for other people is to get it NOW, because tomorrow may bring different results.
[Galaxy Tab 4 Android Development] d_a_ugono:
Why do unofficial ROMs not get OTA updates?
[Galaxy Tab 4 Android Development] V0latyle:
Some can, depending on the development team - but it takes a lot of resources to set up a server backend as well as develop OTA packages, which are not the same as TWRP flashable zips or GSI images. Most custom/unofficial ROMs are developed by one or two people on their own free time. You're basically using someone's hobby, so you shouldn't expect the same sort of support and functionality you might get out of OEM firmware.

Remember...NEVER ask for ETA's, and NEVER demand a fix! As I pointed out, most of our developers work for free, with no compensation whatsoever, and no user is entitled to any of their time and effort.
[Galaxy Tab 4 Android Development] SteinbeckFan:
Is your name in this picture?
[Galaxy Tab 4 Android Development] angryman03:
Does this ROM work with MicroG signature spoofing?
[Galaxy Tab 4 Android Development] crazydrive22:
Yes, it's implemented in crdroid 7 and should work. I've tested it some month ago but there is no big difference in performance to Gapps.

[Galaxy Tab 4 Android Development] SteinbeckFan:
No problem downloading from AFH. Works great. I was tempted to use a different version of BiTGApps, something from plingDOTcom. What they have posted is newer than the build at droidthunder. But it's also ~20MB smaller. So I stayed with what I've been using and works.

I also found a real application for this older tablet, which is an epub Book reader. Let's face it, the Galaxy Tab 4 is slow compared to what's available today. But as a book reader, it's great and useable. I'm using an App called ReadEra. I have no relationship to the App other than to use it to read books in the public domain and available in PDF format.
[Galaxy Tab 4 Android Development] crazydrive22:
Sometimes I use it with the Kindle App from Amazon. Good alternative to a Reader when Tablet is EoL.
[Galaxy Tab 4 Android Development] Arkavator:
I have the same issue, someone please help
[Galaxy Tab 4 Android Development] crazydrive22:
Arr!

Go to Recovery Mode and flash ROM + GAPPS. This will fix the Bootloop. Best Practice is to do this every time.

What android version is the latest build based on?
[Galaxy Tab 4 Android Development] crazydrive22:
It's LineageOS 18.1 (Android 11)
[Galaxy Tab 4 Android Development] andr_SMOLKEYS:
Will there ever be a update based on 19.1?
[Galaxy Tab 4 Android Development] crazydrive22:
Unfortunately no (so far).

LineageOS did some bigger changes in the Source (switch from IPtables to bpf) and we're not able to adapt this to our Tablets. We're working on it but with no success so far.

This also means, that this ROM will end as soon as Google or LineageOS is changing something in the Source. The Devs from Cipher are not longer maintaining this Version.

Pull down the screen from the top twice to expose the gear. Tap on the gear to bring up Settings. The system UI crashes. There's no way to bring up Settings by the gear.

But if you swipe up from the bottom, exposing all the apps. Tap on the Settings Icon. That launches Settings.

Hello everyone,

First of all, I would like to thank crazydrive22 and matteo0026 for this great ROM.

I'm using Samsung Galaxy Tab 4 10.1 SM-T535 and I'm trying out the build "CipherOS-1.7-ASTRA-20230509-1615-matisselte-UNOFFICIAL-VANILLA.zip".

I noticed an annoying issue regarding real-time-clock (RTC): every time I restart my Galaxy Tab 4, the RTC is reset to build date/time (2023-05-09 17:13:24), when "Use network-provided time" is off.

Is this an known issue for You? Is this solvable on somehow?

It is set to sleep after 1 min. of inactivity. It goes to sleep but then 5 seconds later the display comes back on. Does this repeatedly. Anyone know of a solution? Thanks
[Galaxy Tab 4 Android Development] crazydrive22:
🤔

I've never had an issue like that. I'd recommend to clean flash it again. If the issue persist, you should check if there's any trigger for that issue, e.g. a broken display or button.

I get e1001 failed to update system image error 1 on every rom i tried to install, this one lineage 16 or 18.1, i got latest twp, tried chmod 755 on /system and other things, any advices? 5.0.2 flashed with odin works fine but is so outdated and i get force close on apps on and on
[Galaxy Tab 4 Android Development] crazydrive22:
Try tgus

Try this:

in TWRP go to advanced > terminal, then create /cache/recovery with

mkdir /cache/recovery

If this is not working you need to make sure to use the latest TWRP from Matteo0026 and if you have chosen the correct ROM for your device.
[Galaxy Tab 4 Android Development] Sisqo:
I got twrp 3.7.0_9-0 and its matissewifi, the /cache/recovery already exists, still same error, takes a few seconds saying patching system image unconditionally… the base loads till over half then error.
[Galaxy Tab 4 Android Development] crazydrive22:
Did you format /data before flashing?

If yes, you can try to re-partition your device with Odin. You need a 4-Part Firmware and also have to extract the Pit-File from CSC.

Heres a step by step. You don't need to edit the pit-file.

2 Ways to Download and Extract Samsung PIT File

You can easily download and extract PIT from Samsung firmware. You can flash the PIT file on a Samsung phone to re-partition it.

www.google.com
[Galaxy Tab 4 Android Development] Sisqo:
Where can i get a 4-Part Firmware? Pit extracted by renamed csc.zip and pulled it
[Galaxy Tab 4 Android Development] crazydrive22:
You can use this tool

https://github.com/ivanmeler/SamFirm_Reborn/releases

or https://www.samfw.com
[Galaxy Tab 4 Android Development] Sisqo:
I’ve downloaded a few from second link, but don’t know what means 4 part firmware?
[Galaxy Tab 4 Android Development] crazydrive22:
It means the firmware is in parts (like csc, cp, ap, bl) matching to the slots in Odin. In the CSC-file is also the pit-file. For re-partition it's necessary to flash the firmware in parts plus the pit-file (and "re-partition" marked in the settings). It's not working with the one file *.zip
[Galaxy Tab 4 Android Development] Sisqo:
I’ve thought that but can’t find CP file in any of the firmwares I’ve downloaded anywhere else to get it?
[Galaxy Tab 4 Android Development] crazydrive22:
Maybe samfirms.com or sammobile.com but I'm not sure if they have 4-part-fw. Best to use the samfirm tool I've linked before.
[Galaxy Tab 4 Android Development] Sisqo:
Thanks for all tips but no luck. Read somewhere that wifi versions don’t have cp file, repartitioned with pit and the 3 files, os booted normally, wrote recovery with Odin, booted in it, wipe system data cache dalvik and tried installing rom and gave same error. Also tried adb sideload still no luck
[Galaxy Tab 4 Android Development] crazydrive22:
I've downloaded some Stuff for you and put it to MEGA. You should use a different Browser to download this, to make sure there's no corruption. Start with flashing TWRP and the ROM. If it's working you're done. If not, flash the 3-Part-FW with the PIT-File via Odin 3.10 or 3.13. Insert the Files like marked (AP, BL, CSC), insert the PIT-File in the PIT section and check "re-partition" at the options. If this is also not working, i'm out of ideas.

Hello, very new to custom ROMs. Looking for one that I can flash on my SM-T231. Does this work on it? Or can you recommend anything? Sorry not sure if this is the right place to ask.
[Galaxy Tab 4 Android Development] crazydrive22:
Your Device is the 7" Model with a Marvel SoC. We only Support 8" and 10" with Snapdragon SoC. I'd recommend to check XDA for your Device and ask in the comment section or write a DM to the Developer for the ROM your interrested in.

i've tried downloading with edge and firefox too, flashed rom and same error, repartition, flashed twrp again, flashed rom from internal or sdcard same error, i've attached recovery.log with the flashing part maybe got a idea why it hangs there, i've read somewhere that when copying the zip to phone something breaks with the encryption, tried copying with totalcmd also, i've been struggling for a week coz i'm not new into flashing just can't figure it out:) thanks for all
[Galaxy Tab 4 Android Development] crazydrive22:
I'd say you have a broken Partition

about to run program [/tmp/install/bin/backuptool.sh] with 5 args

Backup/restore is not possible. Partition is probably empty

and

Decompression failed with BLOCK_LENGTH_2

missing 1165582 bytes of new data

You can try to re-partition with the PIT-File only. You can also try to use an external SD for the ROM. But i'm not sure if it will help. Maybe @matteo0026 had this issue before and knows a solution?
[Galaxy Tab 4 Android Development] matteo0026:
I've read something about encryption... Hmm, I guess it's better to not use it. Probably it's broken, I've never used it.

[Galaxy Tab 4 Android Development] Catzy96:
Hello @crazydrive22 , sorry i'm a nub, can i use this rom for SM-T331? i've installed LOS 18.1 before but i got some problem with the IMEI 0 and my GPS won't work, it shows the map like on the gmaps but don't show my location, GPS Locker and other GPS tester don't work either, no data shown, even when this tablet supports GPS, will i face the same issues with this one? thank you
[Galaxy Tab 4 Android Development] crazydrive22:
You can use it, it's the ROM for millet3g. I cannot say if you don't have issues with this ROM, because it's base is LineageOS 18.1, too. If you're facing that issues again you should flash Stock ROM 5.x via ODIN and start over from there with TWRP (always use the latest Version from @matteo0026), ROM and Gapps. Those issues are normally caused by a corrupted ROM or a bad Version of TWRP.
[Galaxy Tab 4 Android Development] Catzy96:
Thank you for the fast response. Actually i've been using files from matteo0026 (lineage-18.1-20231023-UNOFFICIAL-millet3g + twrp-3.7.0_9-0-millet from his repo on github), but no matter how many times i flashed it, i encountered the same problem. I didn't know if sm-t331 has official stock rom 5.x, i thought it was not upgradable from 4.4.2, do you know where i can get the stock rom?
[Galaxy Tab 4 Android Development] crazydrive22:
From https://samfw.com/firmware/SM-T331 or other sides with Firmware e.g. Samfirm.

You need to flash 5.x to update your Bootloader. The Region you flash doesn't matter.
[Galaxy Tab 4 Android Development] Catzy96:
Thanks for the recommendation, i've already successfully flashed my device with 5.1.1 rom (KSA region) from the web you mentioned, but i got some issues, No IMEI still and i can't even use my WiFi now, it won't turn on how many times i toogle it, should i just still proceed to flash crDroid?
[Galaxy Tab 4 Android Development] crazydrive22:
Try a re-partition with Odin first.

You have downloaded the Firmware with 4 Parts, right?

Insert it in Odin like they're marked (AP, CP, ect.)

Go to Options and tick "re-partition"

Unpack and insert the file i've attached to the section "PIT"

Flash all the stuff and boot your Device.

Start over with TWRP.

This will write a new partition table to your device and hopefully fix your issues.

Also check the Version of Odin. They're not all working very good. Versions 3.10 and 3.13 seems to be stable. Also have an Eye on your USB-Cable and the USB-Drivers. Both can cause issues.
[Galaxy Tab 4 Android Development] Catzy96:
Thank you, yes i've downloaded KSA build for SM-T331 from the web you mentioned and it contains 4 files, already flashed my device with Odin 3.13.1 and successfully installed 5.1.1, imei was gone, wifi couldn't be used, so i just flashed it to the latest crDroid (from ur github)+ OpenGapps nano with TWRP, successfully installed, my IMEI is still 0, but my wifi is working like it was on Lineage OS 18.1 before, basically i got back to the state on LOS 18.1, tried GPS tester, can't detect anything like on LOS 18.1, should i restart all the work with the re-partition steps you suggested, should i change the region build of 5.1.1??? tbh i've been working on this thing for almost a week now and it's starting to get frustrating hahaha, i actually don't mind if the 3g sim can't work anymore since people are using 4g now, but for the GPS, i think it's an essential thing for a tablet, it'll be usefull a lot...
[Galaxy Tab 4 Android Development] crazydrive22:
Yes, try re-partition. There's probably a broken Partition (mostly it's the hidden Partition, where some basic things for the device are stored). This often fixes several Problems. If not, try a different Version of Odin.
[Galaxy Tab 4 Android Development] Catzy96:
Hello, it's me again. my apologies for my nonstop questions hehe, i haven't tried to do the re-partition thingy u suggested, but i once backed up my previous 4.4.2 stock rom before doing this all on TWRP, in case something happens, i can go back to my stock 4.4.2, so i tried to revert it back again today, i checked the IMEI and the phone recognized it, and then i installed AIDA64 and check the sensor section, something i noticed was it listed all my available sensors on this device, there are 3 sensors, Accelerometer, Grip Sensor for Proximity, and screen flip or sum like that, but when i installed AIDA64 on other roms like lineage os or crDroid it only detected Accelerometer, the other 2 were missing, what's your opinion abt this? no matter what rom i flashed it cannot detect those 2 sensors... will the re-partition thing works?
[Galaxy Tab 4 Android Development] crazydrive22:
You'll find out if you do it. :)

Normally all Sensors should work fine.
[Galaxy Tab 4 Android Development] Catzy96:
Thank you, i'll try it, do i need to check the re-partition option and add the pit file? or only add the file without the re-partition option?
[Galaxy Tab 4 Android Development] crazydrive22:
Yes, you need to tick re-partition, otherwise the PIT-File is not working. And boot your phone once after flashing to make sure everything works with 5.x
[Galaxy Tab 4 Android Development] Catzy96:
Hello @crazydrive22, i've finally succeeded to install 5.1.1 with the re-repartition method you suggested. Thank you, now my device can detect my IMEI, my sensors, even though I don't see the grip sensor on AIDA64, i tried *#0*# the grip sensor is working fine, and i tried to access my location on googlemaps from chrome, and it works to, the only issue is even though the device recognizes my SIM card, it's only on emergency call, do you know what's the problem? can i proceed to install cust rom like crDroid or LOS 18.1? thank you
[Galaxy Tab 4 Android Development] crazydrive22:
Good to hear. Because of SIM, we should ask @matteo0026 who is owning the device sources.

You can install Cipher, crDroid (both A11), LOS (A9, A10, A11) from Matteo or LFR (A10) from @DJABHipHop.

LOS 18 and Cipher 11 should be most performant, crDroid 7 is slow but with a lot a gimmicks.
[Galaxy Tab 4 Android Development] Catzy96:
I mean, i haven't flashed the cust roms yet, i'm still on 5.1.1 now and the SIM emergency calls only problem has been occurring since 4.4.2, but i'll try to ask him..

I'll try to install maybe crDroid or LOS 18.1 after this... thank you
[Galaxy Tab 4 Android Development] Catzy96:
Hello, @crazydrive22 , I'm back again with some more questions. I hope you don't mind. So I've asked Matteo about the SIM card and Emergency Call Only issue, and he said maybe something was wrong with the CSC file of the firmware I flashed and suggested I flash a firmware with the CSC file from my country. So I flashed it back to Kitkat 4.4.2 for my country (Indonesia), but it's all the same; no SIM card works and no network is detected on this device. If I insert a SIM card after restarting, it shows the network carrier for about 5 seconds, and then it will go back to Emergency Call Only. Actually, I'm done at this point; I'll just consider that this IMEI is blocked in my country for some reason. So I'll just move to the custom ROM.

So i need to flash android 5.x as the prerequisite to install cust rom like crDroid or LOS right? Since there's no 5.x rom for my region, could I flash a different region rom? I have a KSA (Saudi Arabia) build of 5.1.1 for this device; can I use it? And should I include all the files, such as BL, AP, CP, and CSC, on Odin??? I have a doubt since it's a different region. Thank you.
