I'm thinking that's milliseconds, so I put in 7000 seconds in my router, which is two hours. We'll see how it works.

Those making these changes should note that lengthening the group key renewal period loosens up security a tiny bit, but should not really be concerned with, just thought I'd share since network security is part of my job.

If i asked the question it is because nothing is written on the 1st posts. I read only issue with BT to tap twice.

If any features of tf300t is not working anymore (i remember an big issue with rom of lollipop from katkiss related to wifi that make watching film on streaming impossible because the internet speed was reduced and also issues of drained battery )

Can someone tell me how long it lasts the battery? Speed of internet is not reduced?

Thanks
[Transformer TF300T Android Development] Artemis-kun:
Just to clarify, the reason for this is due to the current output of the official adapter. It's significantly higher than most other adapters, at 2.2A. Using an adapter with a lower output will cause the tablet to think it is charging off a USB source, so much slower. If you look at the adapter plugs, try using one that has the highest output, and you should get things working if you can find one close to 2.2A.

Hello all

I made the thing that "now I know" I shouldn't have done :( I selected "Wipe Data" in the fastboot menu :(

Now it is in an eternal startup loop, until it rans out of battery

have tried lots of combinations, tried to do something with the ADB, that I am not really sure it worked.

So... what can I do? Is it bricked for good?

Could someone please help me?

Thanks in advance

Dear all,

this is my first post in this forum, that I read for years.

I have a rooted TF300TG with CROMI-x, but I would flash this Custom ROM, even if I'll loose 3g connectivity.

What is the problem? VolumeUp is broken and therefore I can't enter in TWRP via bootloader! :'(

Let me explain better the question:

From system, via adb or powerdown boot options, I reboot my tablet into bootloader;

then, I flash the new recovery;

now, how could I access the newly flashed recovery?

It's very likely that, if I'll try to reboot system, it won't boot, due to incompatible recovery.

Could someone suggest a possible solution? Is, for example,

fastboot -i 0x0b05 flash system myrom.zip

working in our tablet?

Thank you very much in advance!

[Transformer TF300T Android Development] Doc73:
Yes, I know this, but my problem is different: after installing TWRP, how can I start TWRP itself to install this ROM, since the VoumeUp button is broken? :)

I second this question

---------- Post added at 06:01 PM ---------- Previous post was at 05:46 PM ----------

I think you could use one of those apps that require root to boot into recovery on the next boot.

Eh, but if I flash a new version of TWRP, my old JB won't be loaded and the system will be bricked! :crying:
[Transformer TF300T Android Development] t3chwizard:
[MENTION=3951330]timduru[/MENTION] or anyone else that may be able to help with this

These questions may have been asked before, but on the latest version of this ROM I am having trouble getting App2SD or Link2SD to work. The problem lies I think with the fact that the ROM supports so many filesystem types and is automatically mounting all the partitions on my external SD card on boot. Here are my questions in an orderly fashion:

(Q1)-Is there a way to get App2SD and Link2SD to work correctly?

(Q2)-Would there be a way to prevent the system from automatically mounting a certain ext2 (or any other filesystem type) partition? I tried editing the fstab in "/" but it seems to be generated on boot and changes are not persistent.

(Q3)-Is there a way to get the system to work correctly with adoptable storage partitions? I tried using an adoptable storage partition and it recognized it but wouldn't allow me to install or move any apps to that partition.

Thanks in advance. I would really appreciate if someone could help me out with this as I just recently replaced the motherboard in my tablet as I bricked it a few years ago and want to get this working so I have more space for apps and such forth. For clarification I have a 128GB micro SD card and I want to have a ~88GB first partition (ext2 or exfat) and a ~32GB second partition (ext2 or f2fs or whatever works for app2sd).
[Transformer TF300T Android Development] ebonit:
I don't know what do you mean with the broken "VolumeUp" button. Is the volume button of the device mechanically broken down?

In such case there is no chance except replace the button.

By the way, to start into recovery in general needs holding "Power" on and "Volume" down.
[Transformer TF300T Android Development] Doc73:
Yes, I mean the button!

Unfortunately, "Power on" and "Volume down" start the bootloader, where to select one of the three options (recovery, system, full wipe) we need to hold "Volume Up".

Anyway, thank you very much for your response! In short, I can do nothing! :crying:
[Transformer TF300T Android Development] compact_wisdom:
It has been a while since I flashed a recovery, but cannot you still reboot to recovery after flashing the zip file with the Kang twrp? At least in the Kang twrp itself you can always choose to reboot to recovery.

Won't that work after flashing a recovery? What about you current recovery?

Then there is a deassemble instructions at ifixit, maybe that's your backup solution if you get stuck. You have to try finding a place to buy the buttons from.

And I am not completely sure if it is true that flashing a new recovery will keep you from booting your old rom.

HTH
[Transformer TF300T Android Development] Doc73:
Is it possible to flash Kang TWRP inside my old JB compatible TWRP (v. 2.5.0.0)? I normally flash recovery via fastboot from bootloader, but, after flashing in bootloader, I won't be able to select to reboot into recovery due to my broken volume up button.

I disassembled my tab, but the button is fine. I think the problem is somewhere in motherboard.

Eh, as far as I know, latest versions of TWRP are not compatible with Jelly Bean.
[Transformer TF300T Android Development] ebonit:
Nope! You can always do anything. Your efforts are asked. The tablet is it worth. First of all ask Google. Further there is ebay.com for instance like here: https://www.ifixit.com/Store/Parts/ASUS-Transformer-Pad-TF300T-Volume-Button-Flex-Cable/IF287-038
[Transformer TF300T Android Development] compact_wisdom:
There exists a flashable zip file for Kang twrp, that should be flashable in your twrp.

Another thought: you will still be able to boot into bootloader. Then your fallback strategy is:

- flash Kang twrp

- if your Rom is not booting and you cannot manage to get into recovery, boot into bootloader

- flash the latest stock Rom from fastboot

- boot the rom, reboot to recovery using adb or any other method

- install KatKiss

---------- Post added at 08:04 PM ---------- Previous post was at 08:03 PM ----------

My bad, flashing stock will overwrite the recovery, right?

OK, but at least you won't be bricked...

[Transformer TF300T Android Development] Doc73:
It seems a good idea, but

I fear my old TWRP (2.5.0.0) can't flash more recent versions

The latest stock is JB 4.2.1 and probably has the same issues of my CROMI-x (based on stock 4.2.1): can't boot with latest versions of TWRP

Is it possible to flash a ROM from fastboot? How? If yes, my problems are gone!
[Transformer TF300T Android Development] MiniBlu:
You can't install the rom from fastboot (not easily and it's dangerous to try if you aren't 100% sure of what you are doing). What you can do however, is boot to the new kang twrp from fastboot without flashing it (it should work, I have done it on many phones and on my tf101, It can't hurt to try as it dosn't flash or change any thing) Just put the kang_twrp.img file in your adb/fastboot folder then put tablet in fastboot mode and connect to pc, then in fastboot folder type:

fastboot boot kang_twrp.img (replace "kang_twrp.img" with the actual trwp file name)

This should boot directly to the kang twrp and from there you can flash the rom, new recovery zips or what ever you want to do.

I use this method quite a bit on newer phones to keep stock recovery on the phone and only boot to twrp without flashing it when I need to.
[Transformer TF300T Android Development] Doc73:
Ah, many thanks! I know this method, which I used some time ago, but... I didn't remember it!

I tried in my Debian Jessie system, but I had this error:

Maybe it didn't work because in my tablet there is still an old version of TWRP? :confused:
[Transformer TF300T Android Development] timduru:
depends on the kernel

I had made a kernel version that auto swaps /data and or /system mount points to the external microsd on 6.0,

but never got to release it ;)

But it came in handy for a TF300T that had its internal emmc chip fried for example,

I could relocate the system partitions onto the external card.

That's in the kernel ramdisk, you'd need to edit it there and reflash the kernel.

Never really used adoptable storage myself, but I think it's the point.

It's transparent and the system spread stuff between the internal and external partitions.

I don't think you can choose yourself where/when it goes to internal or external.
[Transformer TF300T Android Development] t3chwizard:
Could you kindly release said kernel if I ask kindly with a cherry on top ;)?
[Transformer TF300T Android Development] timduru:
I'll have to dust it off and adapt for 7.1

The other problem was basically that the recovery is not aware of it when you swap partitions like that ;)

So it was not the most user friendly.

I had made a temporary zip file to flash in the recovery before flashing other things,

that would make it work, but I'd have to remember / test again all that before releasing ;)
[Transformer TF300T Android Development] t3chwizard:

[MENTION=3951330]timduru[/MENTION] Here is an update on my attempts to get Link2SD working with this ROM. I reinstalled the ROM with the data partition formatted as f2fs. I have a 128GB microSD formatted with two f2fs partitions (first one is ~88GB and second one is ~32GB). When I attempt to recreate the mount script in Link2SD it says the following error.

link2sd mount '/dev/block/mmcblk0p1'->'/system': Device or resource busy

Not sure why it is doing this, but this is getting a bit puzzling as the partition I am selecting is not mmcblk0p1 it is mmcblk1p2, so this is a bit confusing.

Going to be giving the Katshmallow build a go and see if linking apps to SD card works on that.

It's the same here. I've done everything advised in this thread, adjust my router and so on, but the tablet's Wifi is just like a pinball machine, connected, not connected, connected, not connected....

Hi Doc,

If you have cromi installed, it is possible to restart to recovery. As I remember well it is part of the power button menu, by long pressing the power button and long pressing reboot.
[Transformer TF300T Android Development] Doc73:
Yes, I normally reboot to recovery in this way.

But, my problem is: if I flash in the bootloader the new version of TWRP, how do I reboot into recovery, since I have the "volume up" button broken? With new version of TWRP, I won't be able to boot into CROMI-x.

It's not working on my TF300T. Coming from KatshMallow #29, I formatted /Data and converted to F2FS again, then flashed Nougatella #6, OpenGApps and SuperSU.

I'm using Kang TWRP 2.8.7.2 with all zip packages on /external_sdcard.

Initially I opted for OpenGApps ARM 7.0 nano (for Now On Tap), but that's raising an error: "This GApps pkg is for Android 7.0.x ONLY". When I skipped the GApps installation and rebooted, the TAB halted at the ASUS logo.

I then downloaded OpenGApps ARM 7.0 pico and tried all over again. This GApps pkg will make Kang TWRP crash and reboot straight into recovery again.

***Incompatible Android ROM detected ***

*******GApps Installation failed *******

So it seems like the error is in the ROM...:confused:
[Transformer TF300T Android Development] timduru:
It detects the rom version from the /system partition, so it'd mean that the rom's zip file didn't flash.

Maybe your partition is corrupted or something or your rom zip download.

Try to redownload the rom zip and push it in the recovery.

(maybe try a different method of pushing it, for example if you copied it to your sdcard from another computer, try to push it through adb and/or change storage and so on.. )

You can also try to force a /system format from the recovery,

But check that /system is unmounted before flashing, the rom installer normally will unmount it if it is but in case there's some issue somewhere with your partition, or something you activated in the recovery that will lock the partition, it might be unable to unmount it,

so better check and unmount it manually before flashing.

Then try to reflash rom + supersu + gapps
