So.....this ROM is based off the SM-T235Y. But its just the system and kernel.

This ROM won't change any of the other firmware..ie recovery, modem and boot loader.
[Galaxy Tab 4 General] DAVEGK2011:
Amazing Rom

So far this Rom is working just beautiful.... the only bug that i just found is .... my T235y failed to connect to wifi

it recognize the networks available but it fails to obtain ip address .... other than that seems to be an amazing rom from XDA developers

big thanks to g_ding84

you are my new hero.
[Galaxy Tab 4 General] aftnoon2:
So, we can flash it on the t235lte without problem(except probably bugs)? Sorry for my noob question...
[Galaxy Tab 4 General] g_ding84:
I think I know what is causing that. I'll get that fixed shortly. Did you happen to pull a logcat? There is a missing symlink in my updater-script and I need to see which one. :)

Just a quick question, did you try a router reboot? Did you try to forget connection and then try to reconnect?

Thank you for stepping up.
[Galaxy Tab 4 General] g_ding84:
This is a test version. If you don't feel comfortable they you are free to wait. If you do want to flash it and test to see if everything works, awesome.

With testing there are a few things you will need.

1. A stable backup to fall back on.....ie, make a backup in recovery

2. Odin and your firmware (in a .tar.md5 )

3. Knowledge of how to get yourself out of a bootloop

4. How to pull a logcat.

Its all up to you......every ROM and/or flash comes with risks. It boils down to, are you willing to take that risk? ;)
[Galaxy Tab 4 General] aftnoon2:
Well....I'll try 1st to solve the Nandroid problem, which is my little battlefield by now, after I've changed to a 64gb card...

Then, I'll see the flashing glam...:D
[Galaxy Tab 4 General] TopTongueBarry:
I'll check with RVR, to see if he has a fix. He created the recovery for the SMG-800F which I based this recovery on,, changing the kernel and the size of the filesystems based on the T235 factory settings.

He may know of the 64GB issue and since fixed it on the G800F recovery. If so I'll be able to fix this recovery fairly quickly for you.
[Galaxy Tab 4 General] DAVEGK2011:
First I did try "retry". when it failed again i did try forget and reboot tablet and tried all over again without luck....... ROUTER... i did not reboot router since all other devices were working properly... but i am gonna reboot router tonight and see what happen . other thing that i have noticed is that no predictable text on keyboard even taht predictable text is enable...... something that i can live with..... thanks again for your hard work....

Wi-Fi, predictive text, Model, and LTE Bands

-- Confirming that my T235 failed to connect to wifi it recognizes the networks available, authenticates with the passcode, but fails to obtain an ip address which is necessary to connect.

-- Predictive text no workey even when turned on in settings.

RE: Phone Model and LTE Bands

-- Phone Info + shows that my Phone Model is now showing as a T235Y which isn't really a problem, but the original CSC code and the active CSC code both show (BGL) Bulgaria and the CSC Product code shows as SM-T235NYKATPL (T235). -- Only reason I bring this up is because I am still unable to do anything with the LTE bands of the SS222 on my T235.

-- Even tried to flash the T235Y modem firmware to the T235 device in hopes it would change the LTE bands to from EUR to Tawainese bands thus giving me some hope of eventually enabling US LTE bands on the device after that, but the T235Y modem flash fails to complete successfully, and then leaves the radio inoperable until I flash the T235 modem firmware back on to the device again. EDIT: was able to successfully flash the T235Y modem firmware onto the device using TWRP after I created an updater script, but the radio still doesn't work after a successful flash completion until I reflash the original T235 modem firmware back onto the device.

-- I'm thinking the remaining CSC country/model (BGL and T235) being on my device conflicts with the ROM Phone Model type (T235Y) possibly causing the T235Y modem firmware flashing to fail. I know I am reaching here, but this theory sounds much better to me than another possibility that the SS222 modem HW for the T235 won't support the different LTE bands supported by the T235Y, or any other LTE bands than it came with from the factory.

Anyone have thoughts, ideas, real knowledge or information whether the remnants of CSC in a ROM could prevent flashing a SS222 with a different region's modem firmware versus the SS222 modem hardware of each device T235 / T235Y only being compatible with the LTE bands/freq's it was shipped from the factory with?

I really hope its CSC not HW!

TTB :)
[Galaxy Tab 4 General] aftnoon2:
(Ahem...!:D) Any news about this?

I guess I know what occurs with TWRP: it DO write the bckp, but then, on rebooting, nothing is there. This is the common SD "issue" on KK, but now it occurs only with some apps, I think. I "SD-fixed" my card in any possible way for me...of course.

Right now I'm not able to delete 2 empty folders created weeks ago. Root Explorer apparently does it, but, on reboot, they are there again...

Therefore, I'm able to move files beetwin folders, and delete it.:confused:
[Galaxy Tab 4 General] TopTongueBarry:
Hi g_ding84, any chance of a little more love for our T235 and T235Y's soon in the way of a fix for wifi and predictive text issues? Custom kernel is probably too much to ask for at this point. :)

TTB
[Galaxy Tab 4 General] g_ding84:
Yes sir.....I've been really busy with work and the Fam. Lol such is life. Yes but still trying to figure out the WiFi issue. That's the main goal. I might have to switch the base to the SM-T235 and not the (Y) version.

Would someone be able to pull the whole /system and PM it to me......so I can see what the differences are?
[Galaxy Tab 4 General] TopTongueBarry:
I have a T235, I'm willing to do it, but you should know, I'm back to rooted , stock rom, with a modified csc for Open Columbia (COO) hoping I could force the SS222 LTE modem to work on band 17 here in USA.

Had no such luck with the modem, but the CSC mod is solid. Hate to lose that to only have to do it again, but I will if you need me to and no other offer comes in for whole /system of a T235.

TTB :)
[Galaxy Tab 4 General] aftnoon2:
How to "pull /System"? I have the NJ3 version just rooted....without modem or CSC changes.

It's necessary to flash OB base?

It's just taking Root explorer, copying /system folder?
[Galaxy Tab 4 General] thisisapoorusernamechoice:
Yes except you're going to want to copy that to your PC (i.e. adb pull /system) if at all possible because it's quite large
[Galaxy Tab 4 General] TopTongueBarry:
i don't think you need to flash a base image. Rooted is ok.

copy /system then zip it up and attach it to a PM to g_ding84
[Galaxy Tab 4 General] aftnoon2:
OK.

The copy-zip part can be made this evening (Spain time...), but the sending part must wait till I find a good Wi-Fi connection, not too far from the Andalusia village where I am for some days...:). It's all about not to kill my data plan...

English?
[Galaxy Tab 4 General] corneo:
is there any chance to port a s5 mini custom rom to our t235? the twrp port works too. :confused:
[Galaxy Tab 4 General] TopTongueBarry:
If possible, it would have to come from a ROM made for the G800F or G800M, (exynos3/exynos3470) preferably from the G800M (hardware LTE Bands for South America and ATT US). That's how I made the TWRP port. Unfortunately, the bootloader is locked on the G800A, the AT&T model, so there won't be ROM's for it available right away.

g_ding84 what do you think about his idea?

BTW, I've been toying with using the RIL lib files from the 800A and flashing its modem.bin on the T235, but need to come up with a T235 compatible kernel version and BL they'll work with. Easier said than done.

I know someone around here has successfully done this on another Samsung model, just can't remember which one or find it now/yet.
[Galaxy Tab 4 General] aftnoon2:
Uploading system.zip to Mega.... Not too speedy:rolleyes:

Apologies for this delay. I've been on trip and a little busy after...

Once uploaded, I'll send PM ASAP!
[Galaxy Tab 4 General] g_ding84:
[MENTION=4268788]aftnoon2[/MENTION] thank you
[Galaxy Tab 4 General] aftnoon2:
PM sent to OP! .....:)

Hope this help.
[Galaxy Tab 4 General] aftnoon2:
Weeelll.... Has the /system zip been useful? I'm not asking for ETA, I'm just asking if you need more files or data. Best regards
[Galaxy Tab 4 General] g_ding84:
It was. I'm going with the SM-T235 base and using your system file. There was something wrong with my ROM. It was missing a few lib files.

I know you're not asking for an ETA.....I've been MIA for a bit. I'm working solely on this project to get it stable now. :)
[Galaxy Tab 4 General] aftnoon2:
That's good news! Don't worry, I'm patient...:good:
[Galaxy Tab 4 General] g_ding84:
ALPHA #2 is now posted and ready for testing.......remember to have a backup and odin ready. Hopefully this fixes the WiFi issue.
[Galaxy Tab 4 General] aftnoon2:
That's goooood for Viper! I've dowloaded de app, but it was no so clear to me how to instal the whole stuff... The original T235 sound is pooooor...

I'm a little on the wild side, because my TWRP isn't able to write a permanent bckp on the External SD. But I'll try to flash this soon.

Thanks for your job! :good:

Edit: I'd suggest to add the "Unofficial" SamsungSans.apk, containing more than 100 fonts, as I did on my tablet...
[Galaxy Tab 4 General] g_ding84:
TY for testing.

Viper4Android is pretty easy. Just open the App. choose install (super / High / low Quality) grant SuperUser access reboot when it's all done.

I'll look for the SamsungSans.apk and add it.

Since I'm building this Blind, I need to make sure everything works before I can add in other Mods.
[Galaxy Tab 4 General] g_ding84:
I added a poll in the OP. if you test please leave a comment and vote on the poll (PC view / npt app)
[Galaxy Tab 4 General] TopTongueBarry:

downloading now. will test and post findings.

Thanks sooooo much,

OK, WI-FI DOES Work, but you have to set a static IP address. DHCP does not work for Wi-Fi . checking data (H+) next. What I don't understand is why would dhcp work for the data connection (presuming it still works), but not for the Wi-Fi connection .... More to come via edit later, I still have to add my carrier's new APN after setup completes.

[Galaxy Tab 4 General] juxx2004:

(1) Actually I could boot the system and it contains the stuff you listed in "ROM includes" above. Will do some testing now and report back here then

(2) mobile data works, wifi does not get an IP address but works with static IP.

Looks like the permissions are off for the su files in system/xbin. Not sure why though.....might be off on the permissions in the install script.

I'm not sure what's causing WiFi to not be able to get an IP via DHCP.

Wow, the permissions did fail.

Were you able to pull cache/recovery/last.log(last_log) ?

Too many arg durning the script maybe?
[Galaxy Tab 4 General] juxx2004:
Unfortunately not, didn't know this exists.

And sorry, I cannot repeat it right now as the stock recovery won't install the image due to missing signatures.

...and I cannot get TWRP to start anymore either, just keeps rebooting. No matter which of the images I have got I use.

Gah I need some sleep. I have done it before, just need to remember what I did different last time.

Will retry tomorrow and post results then!
[Galaxy Tab 4 General] juxx2004:
[edit2] Sorry, this is not working.. I'll try the same you did but base it on a rooted stock image created with TopTongueBarry's root, extracted from my original backup.

The permissions for rooting are not even there.

I added this from analyzing the Rom Kitchen code referred to in your image:

(Start/end of changes marked; few context lines kept)

...
set_perm_recursive(0, 2000, 0755, 0755, "/system/xbin");
run_program("/system/xbin/busybox", "--install", "-s", "/system/xbin");

set_perm(0, 0, 06755, "/system/xbin/supolicy");
set_perm(0, 0, 0777, "/system/bin/.ext");
set_perm(0, 0, 06755, "/system/system/bin/.ext/.su");

set_perm(0, 0, 0644, "/system/etc/.installed_su_daemon");
set_perm(0, 0, 0644, "/system/app/Superuser.apk");
run_program("/system/xbin/su", "--install");
## end update by juxx2004
##
ui_print("Flashing Stock T235 Kernel...");
...

I also managed to build the image with Ricky's Kitchen. But due to still not being able to boot TWRP, I can't test it :(

As this is the first ROM I ever built and I don't have much of an idea what all the options even mean, I'd prefer not to upload it but rather if you could add these lines to your ROM install script and build an image for us to test then.

I don't know much about Android, but from my Linux knowledge I'd guess the device name is different because is is different hardware.

The udev config may have to be adjusted therefor. Maybe and/or the script calling dhclient because it passes the interface name.

This is a guess from pure Linux, not Android and may be completely off!

Once I have got a rooted tablet again, I think I can find out and probably also to fix this problem.

From here I can only continue once I found a working recovery image again.

But that's not to be discussed here in your thread ;)

Off to study the forums...

[edit]

It's working again. Big thanks to TopTongueBarry! I'm back to testing myself now again.

Looks like I have a lot of work to do. I'll have to edit the updater-script.

I'm assuming your model is SM-T235. Or is it SM-T235Y? I'm wondering if there is a firmware issue.......wonder if the firmware needs to be updated to match the current build. (Might have to make a firmware only Odin file.)

You shouldn't need to edit the SU files unless you have Samsung Knox...(but it makes it weird that the SM-T237P ROM worked fine)

Can anyone look at the SU files in system/xbin and let me know if they are just 0755 or if they are 06755.

I'll adjust the next build to fix it and update the install binary and updater-script.

HI

I am really glad that people are working on this device also.

Id like to test the rom but since im not using any sim card i need wifi.

Will there ever be a CyanogenMod for this model ? :)

Would be nice to see the phone itself is super good / fast !

Camera and DHCP

Hi There,

I have problem with WiFi - DHCP not working, fixed IP works fine. Another problem is that camera app is crashing after start but skype is working OK, how to fix it ?
[Galaxy Tab 4 General] chripal:
This problem is solved. Clean memory data of app then restart helped.
[Galaxy Tab 4 General] TopTongueBarry:
Yes, we know about the DHCP issue. Thanks for the Camera bug and fix info.

Personally, I am considering coming back to this ROM. I recently moved over to henrymcc's 5.1 CM ROM, but the lack of options in Samsung Service Mode menus is driving me batty. I've tried everything to try to get the Service Modes working in his ROM, but had no success.

At least with this KK ROM, I have about 50 - 70 % of the Service Mode menu's I am interested in working and functional!

If only I could add LTE band's 4 and 17 I'd feel like I was in heaven .......

[Galaxy Tab 4 General] mac231us:
Surprised this works for both 235 and 235Y thought ROMS not interchangeable

-del-

on the T235 now...*#0011# takes me to service menu where I see frequency, dbM etc but cannot do more (on T705 someone said to go to input key = 1 and then do soft back in menu,,nothing happens though

T235 is closest for U.S. imo as it has the band 5 for att

regions unlock does not do anything

I flashed LL build 2 days back came back to KK because needed root..maybe service mode may show something there? doubt it...will try

any input appreciated.
[One (M9) Q&A, Help & Troubleshooting] guyverzero:
Hey all, just got my M9 on Thursday and I've been finding that charge speeds appear to be very slow. I've used the Anker 40w 5 port charger which should auto detect charging speeds and I'm getting 270 mah read on ampere. Is this just an ampere issue, or am I seriously charging that slowly?

I say this in comparison to my GS4, which when using the same charger goes at as fast as 1900 mah (using fast charge. Right now I have it down to 1200). So I know the capability is there, it just seems like the M9 isn't taking advantage of it for some reason). Anyone else having issues with it?
[One (M9) Q&A, Help & Troubleshooting] xxquicksh0txx:
I'm pretty sure ampere is wrong. It tells me the same speed whether I'm using USB on my computer, my oem charger, or my Quick Charger. And they all have very different charge rates.
[One (M9) Q&A, Help & Troubleshooting] brittoking:
Ampere has a hard time with quick charge units. Using a slower charger actually gets you more accurate results. I bought the anker this week as well and it'll sometimes read 290 which I know is wrong.
[One (M9) Q&A, Help & Troubleshooting] guyverzero:
Okay good to know that it's not just me....anyone know of another app that can give me more accurate readings?

Either way hope Ampere improves

[One (M9) Q&A, Help & Troubleshooting] nihil0:
I am the developer of Ampere. I just found this discussion by accident. :)

I would just have to tell that without your help Ampere will not improve. It is not possible that I buy all devices for the development. Please join the Ampere Beta tester group on G+ and please read the Ampere development thread here on XDA. Maybe we can find a way together to get Ampere working with HTC M9 like the Nexus 6 which already works with Ampere and Ampere can detect the turbo charger.

Just did what I think is right as far as troubleshooting goes, and screenshotted the info page on ampere. Still not getting speeds that I think are high enough, so maybe something can help getting it to work
[One (M9) Q&A, Help & Troubleshooting] sdotagain:
I use the anker 40W 5 port charger as well. Ampere is reading about 380-400 sometimes dropping to 290. I have GSAM installed as well and getting similar readings. I just checked this after reading your post. I did notice my phone seems to charge slower than my M8 but I never really looked at the numbers until now.
[One (M9) Q&A, Help & Troubleshooting] michaeldowns:
M9 Very Slow Charging Even With Quick Charge 2

I have a continuing problem with very slow charging even with Quick Charge 2.0 chargers. For example last night I had the M9 plugged into a fast charger for over 12 hrs and it went from 5% battery to 87%. I checked the Settings - Battery usage history - and it displays "NO APPLICATIONS FOUND" - very strange...

Something is very wrong. I have multiple 2 amp and quick chargers all with poor charging times. I have tried 4 different chargers and I tried to post links for the chargers. but the forum rules prevented it.

The Ampere app displays varying charger power from 15 mA to 880 mA so I don't think it is accurate.

Testing with multiple chargers point to the problem in the M9. This is maddening. Seriously considering returning the M9.

Any feedback?
