ASUS TF300T problem partially solved

Thank you for your reply.

Yes, I made complete formatting/cleaning, and conversion to f2fs. So my installation was from zero to system.

All this did not help what I will put as an old hardware system. I also applied some new AC cooling thermal paste and I will overclock CPU a bit and hope all will work smoother.

Actually it is working in a way I can use it, but in everyday use it is not smooth as before.

Yes, I love having keyboard an additional battery power, but there are also some newer choices with dock keyboard out there, so I will think about upgrading my tablet after so many years.

Thank you one more time for your help.

Kind regards,

Hi dear

Can I install this rom to TF300TG ?

is it possible?

Can TWRP 3.4 be used to flash this ROM? I am turning my TF300T on for the first time in years and its on and older 2.8.x build of TWRP.
[Transformer TF300T Android Development] ebonit:
If you have "KANG TWRP TF300T 2.8.7.2@AREA51" you are on the right and safe side. It's striktly recomented by Timduru in the install instructions on post #1 of this thread. But it's also up to you to use TWRP 3.x.

I would like to root and flash my old Asus Transformer tf300tg running android 4.2.1. The tablet is TERRIBLY slow and there is nothing I can do to make it faster. I tried resetting to factory settings, wiping all applications but nothing helped. I am having trouble finding the right instructions. Can somebody explain to me the process step by step?

I found a thread on transformerforums, but my tablet is the tf300tg and it has a different bootloader version than in the instructions, so I'm worried that I might brick it.
[Transformer TF300T Android Development] Snefferdy:
Here's the instructions I used. https://xdaforums.com/transformer-tf300t/general/guide-asus-transformer-pad-tf300t-stock-t3554744

It works, but it doesn't really help the slowness of the device. I think the apps are just too heavy for the the device to handle.
[Transformer TF300T Android Development] ghost_dog333:
Let's talk about lags...

Hi Timduru, hi to other users.

First of all, I’m a Timduru’s roms regular user since his 4.4.4 version. Many thanks for making those roms, alowing us to continue using our olds tablets.

But, as I can read in 6.0.1 and 7.1.2 threads, it seems that some users are facing lag issues / slow tablets.

As it is recommended in several posts, I’m on 27.5 unlocked bootloader with rooted device. Timduru’s 5.1.1 version was working like a charm, even with 20+ apk installed, without lags, but I’m facing now apk compatibility issues.

I store necessary files & zips in the external sdcard, use Kang TWRP 2.8.7.2 Area51, 7.1.2 V039 and last pico 7.1 gapps. On TWRP, I wipe ART, Dalvik, Internal storage, cache and data. Then, I format data. After about 20min+, I change data filesystem from ext4 to f2fs. Thus, I flash zips in the following order : rom, SuperSu and gapps.

After setting up the tablet, I let it settle for around 3 hours. I change some things / apply some tips given by Timduru, ebonit etc. like CPU freq, scheduler.

I install some apks (only 5 : amazon prime video, kodi, xda modded youtube, chrome and tunein radio) and that’s all. The first day, everything goes well. After some days, the tablet begin to lag, for example it takes 20 sec+ to open parameters, youtube vids are stuttering, impossible to open Amazon app due to a tablet freeze etc.

I tried to reinstall the rom as previously described, without installing my apps. Unfortunately, things begin to go wrong again after a week. In fact, I can use my TF300T as shown in Timduru's youtube video during 2-3 days, after that lags are coming.

I saw that what I call system (android, nougat, google play services, interface, launcher) are using around 580 to 650mb RAM on 950mb theoretically free, even more when using the tab. That’s why I face lags when I open an apk, the ram usage is close to 950mb…

I tried on 3 TF300T, same issues with 6.0.1 and 7.1.2 roms. No issues with 5.1.1. I think that android 5 system is « lighter » than 6.0 and 7.0 versions.

For sure, the TF300T has only 1gb poor ram, but I saw 2 things :

-	There’s a zip « low ram enabler » that tweaks android system to something close to android GO system

-	There’s 8.1 GO designed for poor ram devices

For the low ram enabler, it doesn’t work on Timduru’s rom, I read that devs using AOSP basis should validate the low ram system in their rom. For the 8.1GO, maybe we have to wait for the 8.1 development (see TF300T thread, and Nexus 7's thread with a working one) and after that it will be possible to adapt it to the GO version.

Unfortunately, the TF300T is now pretty old with poor ram, and I think that the only way to get it as a daily driver without lags is to use android GO or something close with the low ram enabler patch.

But for now, is it possible to add to 7.1.2 V039 the ability to get the low ram enabler patch to work ?
[Transformer TF300T Android Development] ebonit:
Thanks for your usefull report!

Please note, regarding the actuell Costum Rom Nougatella we have to live whith it like it is because of Tim's last statement. There will be no upgrade on Android 8.0 Oreo. Period!

Nevertheless the TF300T works fine on Android 7.1 and the performance is very satisfactory for such an elderly device. Certainly it's not comparable with new tablets. However it has a wonderful dock and works like a notebook.

You are wondering about the issue that the device getting lagging shortly after setting up. What migt be the cause?

Go to settings and look for the average memory use. It should be between 70% and 80%. After that open "memory used by apps" and look for the culprits which eat the most memory. Finally you have to decide which apps you really need. All other apps uninstall right away. Keep the amount of apps as low as possible!

My device has an average memory use of 738 MB (76%) by 38 apps.

With view on the poor memory it needs frequent care by cleaning cache of apps. Cached data for apps should help them to load more quickly, but it can build up over time to take up quite a lot of space and there will potentially be cached data in there for apps that you no longer use. Sometimes clearing cached data for an app can also help clear up behavior like lag.
[Transformer TF300T Android Development] ghost_dog333:
Hi ebonit, thanks for your answer.

I'm not waiting for an Oreo ROM from Timduru, as you said his last statement is clear and he gave us so much. I'm just saying that others are working on it, a ROM is partially working for the Nexus 7 that have very similar sepcs to our TF300T, but it's not the subject.

As I said, I did a clean install this morning, without adding any apks, just the pico gapps recommended. I can say that the system, in the last 12 hours, is using 60% of the global ram capacity (950mb) : 310mb android platform, 110mb system interface, 73mb google play services, 55mb android system, 15mb launcher3. Thia is when the tablet was settling.

So if I add 5 apps and use it, the ram use grows to 800-850mb, causing lags and freezes...

My question was is it possible to modify the V039 to make it compatible with the low ram enabler patch that is the only thing able to lower the system ram use...
[Transformer TF300T Android Development] ebonit:
I'm sorry for the missunderstanding. The headline of your post is "Let's talk about lags..." and gave the direction!
[Transformer TF300T Android Development] Bozy25:
Have you tried without gapps? search for microg in this thread - for me it was the only way to keep this tablet alive. Installing/updating apps requires some patience but the lags I had were all gone for good.

[Transformer TF300T Android Development] Kockowan:
Hello,

I want to convert a TF300TL (with LTE support) to this Nougat 7.1 rom.

Original TL-firmware ASUS Transformer Pad TF300TL Firmware: V10.6.2.10 Only for WW SKU (Android 4.2) is installed.

TF300TL is unlocked, TWRP recovery 2.8.7.2@AREA51 is installed.

First of all I need to install TF300T firmware, but all known download links are invalid:

ww_epad-user-10.6.1.27.5

Any source for this firmware?

Found: https://www.asus.com/Tablets/ASUS_Transformer_Pad_TF300T/HelpDesk_BIOS/

Second:

How to install this firmware ww_epad-user-10.6.1.27.5?

Is it possible to install it by TWRP recovery 2.8.7.2@AREA51?

What will hapen to recovery?

Thx for any help + best regards.
[Transformer TF300T Android Development] ebonit:
Please search this thread for "TF300TL" and you will find an answer for any question you may have.

BTW, your device is on the correct ASUS firmware WW_V10.6.2.10 dated 2013/10/28!
[Transformer TF300T Android Development] Kockowan:
Yes, should work without LTE/GSM.

But main problem now is, that TWRP rcovery doesn't allow flashing any firmware/ recovery by fastboot.

Device is unlocked, Usb connecting to fastboot ist possible, but if trying:

fastboot -i 0x0B05 flash system C:\Test\tf300\blob

it reclaims "FAILED (command write failed (No error))"

I did try several tipps, for example:

https://android.stackexchange.com/q...-re-partition-internal-storage-to-get-it-back

but it did not work.

How to change recovery, how to get fastboot flash working?

And, if trying to install a .zip recovery, TWRP reclaims /system cannot be mounted ??

Thx + regards.
[Transformer TF300T Android Development] Kockowan:
Post #1872

Is it possible to flash this recovery by still installed TWRP recovery, NOT by fastboot?

Are there different versions of TWRP 2.8.7.2@Area51 available?

I am not shure if installed TWRP version is the 'Kang' version...
[Transformer TF300T Android Development] ebonit:
Please note, you don't need to flash Kang TWRP again. Regarding your screen shot is the right one on your device. There aren't any different versions.

Btw, Josh (@lj50036) has made this TWRP especially for Tinduru's KatKiss Rom on TF300T. As far as I know meanwhile it runs also on TF300TG and TL. The reason was that Team Win Recovery Project (TWRP) at that time wasn't able to change data to F2FS. Furthermore Kang TWRP always does a deeper format data that rewrites everything in the partition. No moldy leftovers. That's very important before any clean installation.

PS: There are two ways only to flash TWRP, Either by fastboot or via Terminal Emulator. :cowboy:
[Transformer TF300T Android Development] Kockowan:
Thank you.

Reflashing the Kang recovery by Terminal emulator did work.

You are welcome! Using the thanks button is always greatly appreciated.
[Transformer TF300T Android Development] ghost_dog333:
Hi Bozy25 and many thanks for your idea. I searched what was microg about, and found it terrible.

I read that microg users usually want to remove google products and services from their phones/tabs as much as possible. I'm interrested in privacy, but I'm not ready to remove all google services or apk (like Gmail, Playstore) but I think that partially cutting datas exchange between our tabs and google servers helped the ram to work properly.

So I erased one of my TF300t, as Timduru wrote in the first post. I installed the V039 rom, supersu, and instead of Gapps, I flashed microG installer from Ale5000 here : https://xdaforums.com/android/development/microg-unofficial-installer-t3432360

It worked like a charm, just a little trick to be able to add a gmail account, but yout have something balanced between full google product and no google services.

My ram use dropped from -25% on core services (android, nougat etc.) and for -36% when I use apks like Prime Video, Kodi etc.

So to my mind, the best mod is to follow Timduru installation instructions with V039 and supersu, and then to use the Ale5000 MicroG installer.
[Transformer TF300T Android Development] ebonit:
Thanks, your solution seems to be better compared to my own with NanoDroid-microG-20.6.20190126. :good:
[Transformer TF300T Android Development] carpler:
Tried a fresh install with Katkiss v039, no supersu and Ale5000 MicroG installer.

Can use the PlayStore, but the first app installed, Jamboard by Google doesn't work: the app crashes immediately everytime.

Why? Is for something missing in Gapps provided by microG?
[Transformer TF300T Android Development] ghost_dog333:
First of all, Hello...

It's good start that the play store is working. I don't use jamboard, some google apk may not work because they need "google features" that may not be included in microg. But as I said for the gmail apk, there's a trick (or treat) to do when you want to log in your google account : switch off the accounts sync in parameters, add your google account through microg apk menu, and then restart your tab. I'm not sure about the whole procedure but you'll find the answer in the Ale5000 MicroG thread someone is explaining it very well.

Let us know if your try worked or not, maybe jamboard will not work with microg system, as microg is a lighter way to connect to Google servers ans using gapps, avoiding to send back (personnal) datas to google...

Install KANG TWRP Recovery

Backup everything !

Boot into the recovery

The first time or everytime you have an issue when dirty flashing (Especially when changing android versions):

do a full wipe , if you have issues make sure that you

format

/data (format is different than wipe)

Warning: formatting will remove what is stored in your internal storage, so store the rom /gapps/supersu zips onto an external storage (microSD, SD card..) or make sure you know how to push them back through adb.

Change /data filesystem to f2fs

(wipe => advanced wipe, check /data then "Repair or change filesystem" => change file system => and choose F2FS)

Then

everytime

(even when "dirty flashing") do the following steps:

Flash the rom

Flash the SuperSU zip

Flash gapps

Wipe cache/dalvik

Reboot

Note that current gapps setup wizard will crash as it is not fully compatible with android 7.1.2 (KatKiss >= 022)

unless you

turn on wifi manually

after the language selection in the initial setup.

(if you don't have a dock, use the extra wifi button in the navbar)

Hey everyone... I would like to re-add my G3 to my sprint lines but the problem is that it was previously rooted and updated to CM13. Usually, when activating via their website, it requires a stock rom. I dont remember what it was on before when I rooted it and the build info doesnt give me any insight. I would like to throw a stock rom on there and activate it then replace with CM13 or even Nougat if that is an option. What is my best course of action?
[Sprint LG G3] SilverZero:
What you just said. Put a stock rooted ROM on (or BareCee), activate, then flash Resurrection Remix.

[Sony Xperia T3] ManFromTheSouth:
Hey guys,

I have a Xperia T3 (D5106), and I followed the step by step process on Sony's developer website to build the Lollipop for it, and managed to build it. However, it seems that the build is specific to D5103, and when I flashed it to my phone, it bricked (bootloop). I had the original TFT so I could get it back up, so no harm done so far.

I took a look at Sony's White Paper, and it seems their hardware are very similar (Processor, GPU, etc). The only actual difference is the support for 4G on D5106.

My question is, is it possible to build the AOSP from source to my model (D5106)? What sort of modifications would involve it? I'm OK with losing a few things, like camera or even the 4G/3G (this is a Dev Phone, so it doesn't really matter).

Also, due to the high similarity, should it have at least worked (I mean, at least boot, even if some things didn't work later on)? So it would mean my build is buggy and worth another shot.
