Which ROM version are you on?

Have you tried a full Odin tar file and see if that fixes it?
[Galaxy Tab 4 Android Development] Fyredragon:
Heya,

Saw your post and had me curious so I went and checked mine. And same as you, my version has went back to 1.65. Very curious as I am not seeing anything else changed in the build. But now am going to have to take a better look in case removing the nav bar is reverting for some reason.

Hope to figure out something or hear from someone else with any ideas

Currently, Acheron 2.0 and it works beautifully. It was installed trough TWRP.

Procedure was carried out in this order:

Wipe cache/dalvik, data, system

factory reset

install su

Install rom

Yes, latest try was with odin 3.10.6 and T230NUOVU0AOG1.

I downloaded and installed a Wifi Fixer app which reports Wifi_state_unknown.

One of the suggestions was to delete /data/misc/wifi/wpa_supplicant.conf file, but there is none.

Second was to give a good whack at the top of the device.

Third, to pull up with needle tool those spring contacts (circled in attached picture) for better connection.

BTW, can someone point to me where the wifi antenna is located?

So far, without success.

Thank you for your reply.
[Galaxy Tab 4 Android Development] g_ding84:
I tested that last night. I can only see my 2.4GHz band as well.

I will have to dig around to see what's missing.

The ROM does come with the T230NU kernel.

[Galaxy Tab 4 Android Development] tatoo069sv:
Thank you ever so much mate. Your a star

PS...i just tried doing it but i have never pushed a file before. I got a boot loop but i just restored my backup. I think i will wait for the flashable zip lol.
[Galaxy Tab 4 Android Development] -=AsteriX=-:
would you plan version for T231?
[Galaxy Tab 4 Android Development] g_ding84:
I would need the stock firmware to make a deodexed ROM.

I do not own a T231 tho. So I wouldn't be able to test.
[Galaxy Tab 4 Android Development] g_ding84:
I'll get one up soon. Sorry bro.
[Galaxy Tab 4 Android Development] tatoo069sv:
No worries mate. I appreciate the time and effort I really do. Awesome rom bro

Hi g_ding84. Is there any chance that you could do the 3 minit battery for this amazing rom
[Galaxy Tab 4 Android Development] g_ding84:
Yes I have been looking into that.
[Galaxy Tab 4 Android Development] tatoo069sv:
That would be amazing mate. It's the icing on top of the cake until lollipop comes lol.

[Galaxy Tab 4 Android Development] c-prodigo:
So I downloaded the rom, which recovery are you using? because with twrp 2.8.0.1 I can't flash anything at all

---------- Post added at 05:26 PM ---------- Previous post was at 05:21 PM ----------

The bad thing about it is that I already deleted the os ..

---------- Post added at 05:59 PM ---------- Previous post was at 05:26 PM ----------

Never mind I sideloaded the rom and works great
[Galaxy Tab 4 Android Development] g_ding84:
recovery was not able to install the zip? I tested on TWRP 2.8.0.1 internal and external storage......flashed fine.

did you by chance pull the cache/recovery/last_log to check what happened during the install?
[Galaxy Tab 4 Android Development] c-prodigo:
looks like transferring from pc to sd card is the problem, downloading directly to the tab, and it flashed without any problems.
[Galaxy Tab 4 Android Development] g_ding84:
SO by request.......REMOVE GOOGLE APPS....

flash in recovery - TWRP

it wipes for you.....just need to flash

LOCATED IN THE 2ND POST under removal mods

Do you really get asked this often? I have to admit my 1st reaction is "You Don't Say" but I guess you put that here since

someone

has to have asked :p
[Galaxy Tab 4 Android Development] LinuxHippy:
Did u install updated navbar.zip? Mine works perfectly in 2.0 ROM as u can see in my screenshot.

Marty
[Galaxy Tab 4 Android Development] Fyredragon:
Heya,

Yea I used the latest one after a re flash of the 2.0 rom. No go reverted back to 1.65 on version number. Not sure what is causing this. Have attached thumbnail to show the version change.

Still open to ideas :)

Dragon
[Galaxy Tab 4 Android Development] LinuxHippy:
No md5sum is posted for the updated navbar.zip but I have this:

c768a70774598439137d7ab72db6245f

Marty
[Galaxy Tab 4 Android Development] g_ding84:
Let me check the zip I uploaded......may be an older version. All the zip does is removes the very last line on the build.prop - something that can be done manually as well.

EDIT :

I verified the zip is the newest one.....in the 2nd post. the correct MD5 SUM for the zip is c768a70774598439137d7ab72db6245f
[Galaxy Tab 4 Android Development] g_ding84:
That was preemptive. I usually do get PMs asking those question so I thought to cover my bases.....lol
[Galaxy Tab 4 Android Development] mkhtfld76:
I downloaded the latest and reflashed and it worked. Think I just flashed the older version,which was the problem.
[Galaxy Tab 4 Android Development] g_ding84:
ok guys update....V2.1 in the works Change log : fixed 3minit and updated HOSTS file (ad blocking)......download available in about 10-15 mins

[Galaxy Tab 4 Android Development] Fyredragon:
But....but..... I'm skeered to install it!!

OK actually am not. Just too late tonight to deal with a dead brain and we all know that means error :)

Thanks my friend for the fixes and updates. Is great to work with someone who does so much for us and tries to make sure we are always happy with our tabs(unlike Samsung) :) Wish we could cheat the 5.1.1 upgrade for the t235 LTE into ours as am sure we have another month or more to go. :eek:

I'll install in morning and let you know

Dragon
[Galaxy Tab 4 Android Development] LinuxHippy:
Got a problem I can't get out of. I installed the new 2.1 ROM twice following the install directions on the first page. That's all I did-I didn't install the removenavbar.zip yet. Maybe that will fix this. The md5 did check out and TWRP 2.8.7 said it installed successfully. It boots OK but then a menu opens up with this:

Unfortunately, keyguardTestActivity has stopped

I press OK to exit the screen and it pops back up in a redundant loop. Any suggestions?

Marty
[Galaxy Tab 4 Android Development] Fyredragon:
Well something wrong sad to say. I flashed the new version and this error keeps popping up every second or 2.

com.android.keyguard

Is the same kind of error like the acore error. I have to keep clicking ok to advance but returns to fast to proceed. The biggest problem is it is not letting me reboot into recovery. Seems like it is ignoring my power/volume keys. After 2 hrs of ideas I finally just kept clicking and typing one letter at a time until I could get in and to play store where I was able to reinstall my rom manager. Once I got that in I could reboot to recovery and re flash ver 2.0 and tablet is acting fine and updating as we speak.

By the above can anyone tell if I did anything wrong or are having the same problem?

I cleared the caches and system etc and flashed like always. but the 2.1 has the above error.

I hope someone has an idea? I am too afraid to try again as it is murderous typing one letter and clearing error over and over to get back to rom manager

Dragon

*edit* seems Marty and I posted about same time. The error he is seeing is the initial one I was getting but as I clicked ok over and over to get through screens the error I posted showed and like he says is redundant.
[Galaxy Tab 4 Android Development] LinuxHippy:
Power key does still work...hold it in a power off. Then use the key combo (Power button/Vol Up/Home) to get into TWRP recovery. I wiped cache and Dalvick cache and then flashed removenavbar but same problem when it reboots. I'm going back to the 2.0 ROM.

Marty
[Galaxy Tab 4 Android Development] Fyredragon:
I tried the combo over and over. The only thing power key would do would turn it off. Pressing the combo would just move volume slider no matter what I did. For now am back on 2.0 until we hear from g_ding as that is a major pain to get out of

Dragon
[Galaxy Tab 4 Android Development] LinuxHippy:
I didn't have as many minutes of my life wasted with this as u, but g_ding84 does put out good software most of the time. He's trying :)

Fortunately my backup of the 2.0 ROM was good and all this took about a half hour.

Marty
[Galaxy Tab 4 Android Development] Fyredragon:
I wasted no minutes per say. Just trying all options until hit one that worked. Figured was the best bet so can try to pass on anything that may help g_ding figure this out. His builds never cease to amaze and little hiccups like this is the life of any builder either roms or software etc. Too many years testing to worry the small stuff :)

Dragon
[Galaxy Tab 4 Android Development] g_ding84:
I dirty flashed v2.1 over 2.0 and had no issues. Let me try a clean flash and see. All I added was the 3minit updated framework and hosts file. If anything the only issue I can see is the systemUI crashing.

If anyone else is having that issue above com.Android.keyguard error please let me know. I'll pull the download links.
[Galaxy Tab 4 Android Development] g_ding84:
com.Android.keyguard is the lock screen and how its handled. It's built into the systemUI.apk. which is what I updated. I'll have a fix for that shortly.
[Galaxy Tab 4 Android Development] Fyredragon:
Great. Glad is something easy. What would you do without us breaking things you build my friend? :)

Dragon
[Galaxy Tab 4 Android Development] g_ding84:
nothing ;) lol - working on a fix. might just leave the 3Minit out of the ROM and just leave it as an optional add-on.
[Galaxy Tab 4 Android Development] mtesa:
Sorry to barge in guys, but I realy NEED your help with stuck wireless.

Can you help or point me in some direction?

Thank you!
[Galaxy Tab 4 Android Development] g_ding84:
V2.1.1 is up. 2 Clean flashes - both worked no issues. WIP on upload to MEGA.

Change log :

Updated HOSTS file to 2015.09.26 source

Removed 3Minit from ROM - saved 21MB total. Optional 3Minit download available in the third post.
[Galaxy Tab 4 Android Development] Fyredragon:
I'll be honest, saw your post the other day and was not sure what to tell you. Then saw g_ding reply and was hoping the fix was there. Am at a loss here as not seen nor experienced this issue. But one thing you might try is install the latest update referenced in post below yours(2.1.1) and see if that clears error. If not maybe a reflash back to stock to see if error still there and if so would lead me to believe you have a possible hardware failure. Not sure what else to suggest other than speak with Samsung tech on the problem if nothing else works and see what they say

Dragon

OK off to see if the wizard of oz has fixed us up :)

Thanks for the work! Will post soon hopefully with good news

Dragon
[Galaxy Tab 4 Android Development] Fyredragon:
OK Went pretty painless overall. 2 google play service errors (like last time) and no more problem since. Odd thing this time....one of the errors actually led me to another issue saying my wifi was not connected. I had to go in and manually set my wifi pw again in settings. Only reason am mentioning it is the other post over no wifi. Wondering if possibly needs to go in and reset it?

Other than that working great g_ding!! Awesome work as always! :)

Dragon
[Galaxy Tab 4 Android Development] r@nsome:
Thank you for all the effort you're putting into this great project. And you're doing us a great favor as the stock rom is blown up with an incredible amount of bloat ware.

I am not sure if I did get this right, but is 3Minit the reason for the keyguard error? I as well got the error and downgraded to 2.0. But if the problem is solved I would like to upgrade to 2.1.1 today :)

By the way, I am having problem with the gallery app in 2.0. It crashes on start ("unfortunately Gallery has stopped"). Is this some stupid configuration caused by me or a known bug?

Best

rob
[Galaxy Tab 4 Android Development] mtesa:
did the 2.1.1 upgrade, wifi is still shot

removed the bar, wifi still shot

tried every single reset or cleaning option, still nothing

settings/connection/wifi/advanced shows MAC address

settings/general/about device/status - MAC address is unavailable

wifi fixer shows WIFI_STATE_UNKNOWN

Looks like my wifi is shot dead.

So now I have realy cool GPS navigation device/MP3 player....... :(

or do any of you guys have an idea?
[Galaxy Tab 4 Android Development] g_ding84:
3minit framework wasn't the reason but my edit to the systemUI was.

I haven't seen the gallery FC issue yet.
[Galaxy Tab 4 Android Development] g_ding84:
I know you have been having issues with WiFi. Even on full Odin stock (no root) you have WiFi issues?

The only reason I'm pushing it is there may be a modem issue with the new firmware.

Before I rebased this ROM on XXAOD1 firmware, I did a full Odin flash (System, kernel, boot loader and Modem). I'm trying to make a modem only flashable zip and Odin .tar file for an upgrade.
[Galaxy Tab 4 Android Development] LinuxHippy:
Does your WiFi work in the stock ROM?

Oh, your picture of the open tab was impressive. Did plastic tabs just keep it together and were u able to close it back without broken plastic tabs?

Marty
[Galaxy Tab 4 Android Development] r@nsome:
Great g_ding84, I will give 2.1.1 once I get home.

I am just curious but do you also think that the t230 is pretty slow even on this bloatware free rom? This marvel cpu seems to be the problem :(
[Galaxy Tab 4 Android Development] mtesa:
WiFi was ok with stock ROM. It failed after Samsung update. I downloaded two files called T230NUBNN0AOG1 and StockRoms-Series_T230(NU)+V1.6.3.

Without success.

Yes, it is properly closed.

Btw, I just realized, g_ding84, you made an excellent job with this ROM. It is much much better then stock.
[Galaxy Tab 4 Android Development] Fyredragon:
OK I would fully suggest a restore to stock and see if the error clears on wifi. If it is gone then would try to re flash back to latest build and see if it returns. By doing this, it may be your only way to figure out if it is a hardware error or maybe an issue with the flash of the build. As you are only one I am seeing so far with this error I would definitely try to bring to stock and proceed from there.

Maybe some answers will be found that way is all I can suggest without the actual tablet physically here

Dragon
[Galaxy Tab 4 Android Development] Fyredragon:
Heya r0b,

With the removal of so much crapware the tablet instantly feels quicker. below is a link to CTXz thread where he developed a tweak for the cpu that is remarkable in adding snappiness to the tablet. I use it and love the difference in some of my games and overall usage of my tablet.

http://xdaforums.com/tab-4/orig-dev...b-4-t230nu-t3101944/post60572872#post60572872

Hope that helps you feel a bit better about your tab as these devs here do a lot to make a moderate tablet feel like worth having :)

[Galaxy Tab 4 Android Development] whoisthedrizzle:
Just wanted to hop in and say thanks for what appears to be the only viable ROM for this device. I exclusively use nexus devices so this is proving to be an... Adventure.

With that said I am having huge WiFi issues as well. I flashed this ROM to see if it would fix the spotty wifi speeds from stock. That is to say that 5 free from the router I was getting about 3M down and 1up whereas my nexus 5 on the table next to it gets like 70/10. This ROM significantly improved my speed (20/8) however only if I'm in the same room as the router. As soon as I go over 10 feet away it ****s the beds in constantly disconnects and reconnects however when reconnecting there is no throughput, just an eventual time out.

Also getting a lot of acore crashes. But I seem to be working through those.

I am a new to this device.. Was gifted to me from a relative no longer using it, but Ive been doing this **** since the OG g1 and nexus 1 so consider myself fairly experienced in troubleshooting. Very spoiled with nexus devices and working with this just to get it debloated and useable is like being back in 2009/2010.

Really not sure what to do after wiping/flashing a dozen times. It seems the wifi controller in this device is just trash. My choices seem to be super slow wifi with a buit of mobility around the house or acceptable faster wifi in one room.

If anyone has an idea or advice for me please send it my way. I may flash the second to latest update and see how that goes.

It's really a bummer there are no AOSP or CM based roms for this thing after almost 2 years. I wish I knew more to contribute but if I did I likely would join the bulk of devs in not bothering with this bastard device. Anyway sorry for the rant and thanks again for taking the time to support this device.
[Galaxy Tab 4 Android Development] LinuxHippy:
I've never had any WiFi problems with the galaxy tab 4. I've read about people having issues with dual band routers. I have single frequency 802.11N router.

Marty
[Galaxy Tab 4 Android Development] g_ding84:
I have a dual band "N" class WiFi. This tablet can't see the 5GHz band but the 2.4GHz connection is decent.

Also, I had to upgrade my Router Firmware last week. Every device was dropping connection. After the firmware upgrade and router reboot, no more connection issues.
[Galaxy Tab 4 Android Development] Fyredragon:
I also have an N class dual band and right now am downstairs from second story apt. posting this. I am probably 75 feet or more from my router and showing a pretty constant 2 bars with no problem at all staying connected. Not sure why some having problems as this of my three tablets seems to keep the best connection of all of em.

Dragon
[Galaxy Tab 4 Android Development] r@nsome:
Hey Dragon.

It sounds great, thank you for the advice. Does the overclocking has an effect on the battery drain?

Best

rob
[Galaxy Tab 4 Android Development] Fyredragon:
None that I have seen. I play a couple of games that are pretty intensive on power and with the tweak the stuttering is all but gone and no real seeing of worse drain with or without.

Dragon
[Galaxy Tab 4 Android Development] r@nsome:
Ok I gave it a try and am impressed as the difference is significant :) I will now test it out and check the new kernel on the long term.

Thanks for the hint!
[Galaxy Tab 4 Android Development] Fyredragon:
Glad to be of assistance. As much work as I have with windows 10 is a nice change to mess with my android stuff and not see windows in my sleep :)

Dragon
[Galaxy Tab 4 Android Development] r@nsome:
Ok if Windows is already in your dreams you may need a change :) Try a good Ubuntu or maybe Mac osx!
[Galaxy Tab 4 Android Development] g_ding84:
+1 for Ubuntu ;)
[Galaxy Tab 4 Android Development] mike2nl:
+1 for Gentoo ;)
[Galaxy Tab 4 Android Development] mtesa:
Was chattting with some "lucky and satisfied" users of this device, apparently there was significant number of these devices with faulty wifi hardware.

well, so far looks like I'm one of them too.

For one last chance, can someone recomend the download location of stock ROM, as well as step by step guide how to flash it "to the bone".

I was so much into this, that everything is a big mess and blur inside my head.

Thank you guys.
[Galaxy Tab 4 Android Development] Fyredragon:
heya,

sorry your are having such a bad time. Wish I had hands on to that tablet as there is something really odd. I have two other friends near me who have the same tablet as I and none have had this problem. If still new enough, is it warranty applicable still? If you un root and revert I mean. Anyways here is a link with everything you should need to totally revert. This thread full of the info you will need.

Just got a word from samsung representative, if I could get to Cork or Dublin to authorized service. I live in Bosnia. So,..... no.

If you don't hear from me in couple of days, you can freely presume that this tablet ended in my car as GPS&MP3 device :)

+1 Linux Mint
[Galaxy Tab 4 Android Development] g_ding84:
Yes it does.

Give a bit of time, I can make a zip to fix that.

If you have another ROM zip on your tablet, extract the settings.apk from the zip and push to system/priv-app (overwrite the existing settings) set permissions to 0644 - reboot to recovery - wipe cache and dalvik cache.
[Galaxy Tab 4 Android Development] g_ding84:
That's messed up.....is there an option to mail it back to Samsung for repair/replacement?

I'll wait for the zip but huge thanks!
