Kind sir, would you kindly port cm12.1 for our tab ? Will test it for you once it is compile
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] iampatricktan:
Sorry late reply. Yes i can test it for you. Just need latest 6.0.1 firmware and debloat it
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] glockman4519:
I can also test for you and would be happy to . Just let me know.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BeeGee_Tokyo:
Thanks for the info for Exposed. Did you actually test it and is it working?

A CM ROM will be quite difficult, as I don't have a device tree for the SM-P355 nor a CM compatible kernel. So impossible for now.

Will try to build one from original source. Just give me some time.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] glockman4519:
Absolutely. Take all the time you need. I am not going anywhere..lol.. I am running the stock build that came on my t350 and have extremely debloated it.. so much so that the stock camera isn't working any more..lol... Web a little too far. Other than that this tablet is very nice for the specs.

Any build that you come up with for this tablet, I will be more than happy to try out fit you.

I was thinking about what you said about a working CM kernel, http://xdaforums.com/showthread.php?t=3489091 this rom is CM based and I tested it. It boots and functions. Could be a source for a kernel if you ever decide to try and build CM for this device.

Once again, thank you very much.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] budakmashoor:
Yes did try and xposed work well, as far as i use it, no problems noted. Some of the modules were quite essential for me. As for CM, its ok, we can wait.

This rom work but cant turn on wifi

Hi there.

after i install this rom and it work until i try to turn on the wifi

the wifi cant turn on

have any fix patch ?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BeeGee_Tokyo:
I am using this ROM since 6 months and had never problems with the WiFi. So I do not know what is causing your problem. Maybe you can try to make a clean and fresh install of the ROM and enable WiFi before you install anything else.

Due to time restrictions I stopped developing Android ROMs for the moment. I am sorry, but I do not have time at the moment to even look into your problem.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] BeeGee_Tokyo:

[MENTION=1360332]BeeGee_Tokyo[/MENTION], naah its alright, im thankfull that you even spend some time making this ROM. Cheers dude

as for now, everything working perfectly, well i think what cause wifi problem was when im Flashing your ROM im using 6.1.1 os.

all had been well after i reflash back 5.1.1 os (from www.samsung-firmware.org) and Flash back your ROM.

only problem so far, after i update my supersu or my Xposed, somehow the "not enough storage space" pop up and i cant install any App,

so if i dont Update SuperSU and Xposed then all is well.

CONFIRMED: ROM STILL WORKS JANUARY 13, 2023

Wifi problems get resolved when downgrading back to Lollipop when your SM-P355 has had an OTA MM update.

I used P355XXU1AOJ1_P355OLB1AOJ1_P355XXU1AOE9_HOME.tar.md5 using Odin to go back to Lollipop.

Then I installed TWRP, wiped the device, and finally installed the custom ROM.

Caution: use official Samsung firmware to downgrade. Use your due diligence to look for the correct stock ROM. Ain't anyone's fault but yours if you flash a sketchy one to your tab. I think there's an official way mandated by Samsung but I used Odin for the heck of it.

[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Hi everyone!

After three years of a very PAINFUL experience with my TF300T, I was about to throw it out of the window. But I actually thought that I could maybe try to install some custom ROM to make it work better.

The tablet is really almost unusable, because of the fact it is so slow. Youtube videos lags beyond imagination and often the audio desyncronizes with the video itself. Browsing experience is equally sluggish with either the stock browser and chrome.

I would like to ask you guys which ROM you think is the best for these things: Youtube watching and browsing. Of course I could use other apps, but this is the main purpose of the tablet for my actual needings.

I have been reading about Katkiss roms, but there are a few versions around and I really do not know anything about flashing roms and customizing android devices. This would actually be my very first time.

The only thing I did was reverting the tablet to Android 4.1 with the official Asus installation file. After a couple of days, noticing I wasn't experiencing any significant improvement, I let the tablet automatically update again to the latest 4.2 version through the update function.

Considering this, I would also kindly ask you to eventually link me the NOOB PROOF installation guides for the ROMs you will advice me to install. I am quite scared to just destroy the tablet :confused:

Thanks in advance to whoever will spend some time to bother answering me! And sorry for any grammar mistake I could have made writing this, english is not my native language.

[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Being on the last Asus firmware update is a good condition to think about installing a custom rom on your tablet. However first of all you have to do your homework as follows:

1. Unlock your boot loader with the Asus unlock tool after download from the Asus web site,

2. Install the custom recovery Kang TWRP 2.8.7.2@AREA51 (http://xdaforums.com/transformer-tf300t/development/recovery-twrp-t3046479). There is also the install instruction!

After done this both successfully you are ready to install one of the best custom rom ever "KatKiss Nougat 7.1 Release" http://xdaforums.com/transformer-tf300t/development/rom-t3453702. Download the latest Rom, Gapps and SuperSu there in post #1. Please follow the install instruction given by the developer in post #1 exactly . After that you will enjoy the new life of your tablet.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thank you for your answer!

I have already downloaded the latest Asus unlock tool (version 8) and I'm waiting for the tablet to charge to 100% before doing anything.

I have also take a good look at the KatKiss Nougat 7.1 version 12 you linked me. I understand this version is quite new, so I guess it could be less stable and optimized than the older Marshmallow version. I have also read a few people complaining about wi-fi disconnect issues (which I would definitely hate to have).

I do not care about a specific android version for my tablet, I just want it to run smoothly and without any issues and headaches :) considering this, would you advice me to install the Marshmallow version or the latest Nougat one?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Finally it's up to you which one you are going to use. I had been on MM 6.0.1 since version#10. Now I have been on N 7.1.0 since version #6. I have never had any problems with WiFi, Audio, Calendar or something like that. All versions run very well, smoothly and stable.

However in both cases you need Kang TWRP in order to be able to format /data to F2FS. This gets the better performance.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thanks again for the time you spend answering a total noob :)

At this point I would like to ask which version do you actually like the most, before deciding myself.

Plus, I'm getting ready to install everything, but I'd need some confirmations first.

I have just successfully unlocked the boot loader.

Now, to install the Kang TWRP, do I need to download something called "fastboot"? I read this on another guide, because the actual link to the Kang TWRP doesn't exactly tell me how to properly install it. Or at least, I feel like there are advanced instructions I can't fully understand.

After installing the Kang recovery, the guide says I should do these things:

1) do a full wipe , if you have issues make sure that you format /data (format is different than wipe). I guess I can do the WIPE from the recovery menu. Should I format /data after said wipe? If the answer is YES, how should I do that?

2) Change /data filesystem to f2fs. The guide once again doesn't tell me how should I change this thing.

3) Flash the rom. I guess I have to install the ROM from the recovery menu.

4) Flash the SuperSU zip. I assume I can do this from the recovery menu aswell

5)Flash gapps. Always from the recovery menu?

6) Wipe cache/dalvik. No additional info is provided, how should I do that?

7) Reboot

Thanks in advance for the clarifications eventually provided :) I feel like I'm just adventuring myself in a new, huge world.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
First of all you need „Minimal ADB and Fastboot“. The USB driver must be installed on your PC.

Download “Minimal ADB and Fastboot”. Make a folder C:/Fastboot and extract it there and install it on your PC. Download Kang TWRP and put it into the folder C:/Fastboot and rename it to twrp.img

Start your device in fastboot mode and connect it with your PC. Open “Minimal ADB and Fastboot” and put in "fastboot devices". The device should appear as "xxx device".

Put in "fastboot -i 0x0B05 flash recovery twrp.img" without " ".

After that you should have Kang TWRP. Format F2FS with TWRP: Wipe => Advanced wipe, check the box for data then click on Repair or change file system, then click F2FS. But /Data only not /System or /Cache!!!

Finally do all 7 steps. Flash rom, gapps and SuperSU in one run. Wipe dalvik/cache. After that reboot.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thanks, really! You're very kind :) I'm already downloading everything needed.

Which version do you actually prefer? Are there any difference on the battery life between them?

And also, if I install for example Nougat, can I eventually revert to Marshmallow if I want to?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Of course, but it needs always a clean install (format data).
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
I'm trying to install the recovery, but it seems that something is going wrong.

This is what appears on the screen:

C:\Fastboot>fastboot -i 0x0B05 flash recovery twrp.img

target didn't report max-download-size

sending 'recovery' (7126 KB)...

OKAY [ 2.805s]

writing 'recovery'...

OKAY [ 8.019s]

finished. total time: 10.825s

After that, it seems that nothing has actually changed. I tried rebooting with C:\Fastboot>fastboot -i 0x0B05 reboot but it just reboots normally. If I try going in recovery mode, I still have the old stock recovery mode.

What am I doing wrong?

(Ofc, in the meanwhile I'm pressing the thanks button :) )
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
What bootloader do you have? MUST BE ON A BOOTLOADER ENDING IN 27.1 or 27.5.

Please check starting fastboot by power on and volume down. In the left corner should appear "WW_epad-10.6.1.27.5".

Thanks mate! Really!

I am experiencing an issue though. I am getting wi-fi disconnecting every couple of minutes, or even less. I've also written in the marshmallow thread, hoping to get some answer.

Is there a way to fix this? Will eventually the new build Nougat solve this?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
I'm sorry, but I have no idea. Timduru suggests "Try increasing the group rekeying interval on your router".

If I were in your boots, I would try a clean installation of Nougatella to see whether it's solved or not.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thanks as always for the suggestions.

I had some time today and flashed Nougatella. Unfortunately, the wi-fi issue it's still there. No sign of improvement at all.

I'm starting to get a bit mad on this. Is there any previous version without any known wifi issues? I am even open to try other ROMs. I just want my tablet to be good for internet browsing and youtube watching...
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
I'm so sorry for that because I was very hopeful the issue will be solved.

First of all, please check your tablet within another stable network like a free WiFi somewhere. If there is still the same trouble please make a logcat and send it to Timduru. Maybe it helps to figure out the cause. Using the terminal emulator: su ->logcat. Save the file as "logcat.txt".
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thanks for the tip. Unfortunately I don't actually have the time to test other wi-fi networks, and above all, it would still pass A LOT of time between my log sending to timduru and EVENTUALLY him taking care of the issue (provided he would).

I'd need a quick solution to make the tablet work again, considering I haven't been using it for days because of this wifi problem.

Would the Lollipop katkiss version work with the same recovery? Are there still people lamenting the same issue even on lollipop?

Can you please tell me if there are any other decent ROMs I can try with the same TWRP recovery?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
My Dear Kalynor , I can understand your final intention getting your tablet working as fast as possible.

Before I went to KatKiss I have been on Cyanogen Mod 12.1. I have been very satisfied with that rom. It was a relevat progress to the stock rom JB at that time. This is my only one experience with a CR before. Cyanogen Mod 12.1 is a stable running CR on Android 5.0 LolliPop. You should try it in order to learn that WiFi works well. Because of MM 6.0 at that time I changed to Timduru.

You don't need a new TWRP as far as I know although every TWRP higher than TWRP 3.5 is also right. I don't know if CM 12.1 accepts changing /data to F2FS. That' the most important thing on Kang TWRP. What you need is:

1. Cyanogen Mod 12.1 latest version download here: http://get.cm/?device=tf300t

2. Gapps "gapps-lp-20150222-signed" download here: https://basketbuild.com/filedl/gapps?dl=gapps-lp-20150222-signed.zip

3. SuperSu latest version you already have.

Put the all files on your extern SD Card and make a clean install like advised for Nougatella with format data. I think you will get it being on CR 12.1 right away. Hopefully your WiFi will work well.

PS: By the way, there is also another CR in our thread called OmniRom. It's also a Nightly. You may have look on this thread because I didn't have had yet. http://xdaforums.com/transformer-tf300t/development/rom-omnirom-tf300t-t3054886
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
As always, I have to deeply thank you for all the time you are spending helping me. I really, really appreciate that, especially considering that I'm absolutely new in this kind of things.

I am already downloading the latest CM 12 nightly. I just read that "nightly" means it is no absolutely 100% stable, but I guess it's better that having no wifi :)

So, will my actual TWRP recovery be ok for that flashing? Or I need to install the dedicated CM 12 recovery? I would prefer to stay with TWRP honestly, to avoid further troubles.

I will do exactly as I did with the katkiss roms. One last question on that matter: when you have to do a "full wipe", does it mean you have to manually select every folder (dalvik, cache, data, internal storage and another one I don't remember) and then wipe right?
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
The actual TWRP will be OK to flash rom, gapps and SuperSU. Doing a "full wipe" means

factory reset

on your tablet. You don't have to do anything manual. But all data on the internal memory will be deleted. Back up data you want to keep.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
You won't believe me...but I tried both the Cyanogen ROM and the Omnirom. In both cases, wifi didn't work properly. It was just slow as hell and of course, always disconnecting.

I really don't know what to do at this point. Any idea? :(
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
As far as you may remember I recommended to you to check your WiFi by using another network like free WiFi in a restaurant or somewhere else. I suggested from the beginning the odd behavior of your WiFi depends on your home network. Timduru also advised in suche case to change rekeying.

Please go to your modem's/router's WiFi security settings. If WPA/WPA2 Group Key Update Period is zero or disabled, you must change it. Set WPA/WPA2 Group Key Update Period to

86400

. Save your settings and reboot your modem/router. Hopefully your problem will be solved.
[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Dear ebonit, I did as you suggested and put 86400 on the group key update setting. Did a a bit of testing and it seems that the things actually got better! The problem is not entirely solved, but wi-fi dropping has decreased significantly.

I can finally do my internet browsing and watch my youtube videos without too much trouble.

Thank you so much for all the help you kindly provided :) I'll keep you updated when I'll have the time to do more testing.

Also, I'll keep my eyes open for Nougatella updates. Hopefully the problem could be definitely solved in the future.
[Transformer TF300T Q&A, Help & Troubleshooting] ebonit:
Thank you very much for your kind report. I'm glad to learn that my advise helped in general to find out that WiFi dropping mostly depends on the network the tablet is connected to. You did a really good job and in my eyes you accomplished successfully the jump from a junior member to an experienced member in our forum. Congratulations! :) Go ahead!!!
[Transformer TF300T Q&A, Help & Troubleshooting] kozmo2k4:
A few months back, I had something similar going on with my WiFi. Actually, I could not use any other ROM than the last CM11. With newer CM, 12 and 12.1, as soon as I flashed gapps, I would lose WiFi completely (stuck on Turning On).

So I went ahead and brought the tablet back to full (latest) stock. Kept it for a few days, to make sure all was working good. And it was.

Around that time, the Nougatela ROM came out, so I wanted to try that.

Full wipes, TWRP-kang, and I was on my way to a very happy tablet.

Couple of months later, I have no intentions to go to another ROM.

I don't know if it was the stock ROM, or the two full wipes, or a combination of both, but that worked for me.

Electronics are finicky like that sometimes ...

[Transformer TF300T Q&A, Help & Troubleshooting] Kalynor:
Thank you so much! I could never have done all this without your precious, patient and kind help. It is pretty hard to find someone willing to help a complete newbie in this field :)

Not only I finally have my tablet working WAY BETTER than it has ever been, but I feel like I would definitely try the same thing with my smartphone in the future. You helped me enter the world of custom and better ROMs, and I will never be able to thank you enough for that.

On a sidenote, in this last 2 days the wi-fi has been working pretty fine :D the problem is, if not solved, barely noticeable. I experience a little trouble just on the very first connection to the router. Once connected (after a few tries), it works almost perfectly and rarely drops. I am actually very happy of my new tablet.

It's just like a brand new device!
