Sorry, I've been out of the TWRP upgrade scene in a while. Can anyone tell me if there's a FULLY functional build that works with JB AND supports large SD cards?

I'd like to be able to backup my ROM to SD for safety's sake, but the old versions won't work with my 32 or 64GB SanDisk Ultra cards and the new ones fail on the backup due to 0-size boot partition. I've seen a post for a russian built 2.6.3.1 but it says it only works with 4.4 roms. Can anyone confirm if this works with CROMI-X?
[Transformer TF300T Android Development] cmendonc2:
The 2.6.3.1 will only work for 4.4 builds, as you said. CROMI-x will not install. Make sure you are installing the right TWRP -jb for 4.1 and -42 for 4.2 bootloader.
[Transformer TF300T Android Development] :
i flashed the twrp 2.6.3.1 for cm 11. Now i would try Cromi X rom. Can i flash directly the twrp 2.5.0.0? My bootloader is 10.6.1.27.5, which recovery ics o jb? thanks
[Transformer TF300T Android Development] f69m:
Yes, you can flash it directly, but use the -42 version. Both -ics and -jb are for an older bootloader.

Will it work on the ASUS TF300T /G as I have seen the developer Dees Troy said TWRP 2.7 will not be supported on these devices anymore?

I presume you made modifications?

TF300TG on Omnirom nightlies forgo the 3g to try get a non laggy device with a custom rom.
[Transformer TF300T Android Development] scanno:
Well TWRP is part of the omnirom build tree. So to make omnirom build, you will need a basic twrp setup and it has to compile. Perhaps Dees_Troy is not supporting the tf300t anymore. But as long as it is building and keeps working and I can make the needed changes to the device tree, then I will post new versions.

Hello everyone

today I jumped in mind one doubt:

I (as mentioned above) are still on the TWRP 2.5 and would like to upgrade to 2.8.0.1,

I can do it from the terminal of the tablet as described here (http://www.teamw.in/project/twrp2/97)

or force or to be safer I have to use the zip ??? :confused::confused::confused:

thanks

Edit: Post moved to the more recent discussion!
[Transformer TF300T Android Development] Lex_Michdeandroid:
I'm a little confused now, because I can't understand what is happening to my tablet. Let me explain step by step what I did, maybe one of you can figure out what is wrong.

I was running CM11 M12 with TWRP 2.8.1.0 and wanted to try the new Android 5.1. I decided to go with the latest Omnirom and found out I needed at least TWRP 2.8.5.0.

So first step would be to update TWRP. When I got at the TWRP website I read that there was something new in TWRP 2.8.4.0, so I decided to first go from .1 to .4 and then go to the latest .7. An upgrade to .4 went fine through Fastboot. Then I thought I could try the new in GUI recovery flasher, but I didn't understand it properly so I chose to go safe and flash the .7 through Fastboot.

I guess that's where I went wrong. The tablet went to recovery just fine, but in TWRP it couldn't access anything anymore. "Unable to mount" on everything. Internal storage was 0. It didn't boot to the ROM anymore.

So after some tinkering, not really sure what I did anymore, I got my access to the FS again. I had the CM11 M12 ROM still in the MicroSD, so I ran the "install ROM procedure" for that one and it booted again.

Only now I don't seem to have a recovery anymore. I can get into Fastboot, but when I send the "fastboot -i 0x0b05 flash staging twrp.blob" the tablet hangs itself. Holding power revives it and it boots to CM11M12 again. I tried to flash different TWRP versions (.4 .5 .6 and .7) but no sigar.

Does anyone have an idea how to get my recovery back?

Edit0: I tried to install the TWRP manager from the store and get a recovery from there, but the app doesn't work. It hangs when I try to tap on the "Recovery version to install" option.
[Transformer TF300T Android Development] ch3mn3y:
I think You need to flash stock and than start again. Best TWRP I think, is KANG unofficial one, but You need to flash it using dd command via Terimnal or Fastboot.

And thats only one 2.8.7.x TWRP for our tablet (?), so I don't know which one this app tried to flash.

You need to reflash stock firmware via fastboot to get back to fully working device. If u need to make backup try to use Online Nandroid Backup app. Remember that fastboot will wipe all Your data!

Similar scenario happened to me, flashing 2.8.7.0 from within 2.8.5.0.

No need to fully wipe/erase the whole device to get the recovery back.

All I did was boot into bootloader ("#adb reboot bootlaoder") and executed the following:

I did not do any data or system wipes. After a full system reboot, I got back to recovery, to verify it does indeed work, and then wiped cache and dalvik cache.

Hope that helps...
[Transformer TF300T Android Development] residentorca:
I successfully updated TWRP recovery using the fastboot method and the twrp-2.8.7.0-tf300t.img file. Everything works fine except the reboot to system and power off options, which both result in a reboot to recovery. While in recovery, I can power off by holding down the power button. I can live with this glitch but I am curious what may be causing it.
[Transformer TF300T Android Development] pnomandk:
Just FYI: There is also another (known) bug in that you cannot convert a filesystem to F2FS due to a version mismatch between the GUI and the mkfs tools (IIRC). It can be fixed by rebuilding the image file after editing one file (twrp.fstab) and the reflashing.

I also had some issues flashing and trying to reformat my other partitions and had to resort to "fastboot erase ..." to recover one of them, but this could perhaps have been something else and not the 2.8.7.0 version of twrp.

I've since change to the 2.8.7.2 kang unofficial/no longer supported/... version from another thread, and that allows both conversion to F2FS and rebooting (which is surely a minor glitch). Not sure if it has other errors that I just haven't seen yet :)
[Transformer TF300T Android Development] Higgy69:
Snap, me too!

Tried updating to latest Kang.img via TWRP and now it won't go into Recovery but everything else works fine.

I have the official twrp-2.8.7.0-tf300t.img and serious issues with F2FS. Formatting /data to f2fs from TWRP failed, because version mismatch: invalid option -- r.

Manually formatting like mkfs.f2fs -t 1 /dev/block/mmcblk0p8 worked, any CM12.1 can start with it. But TWRP itself does not start anymore, hangs at the boot screen. From dmesg:

Can't find a valid F2FS filesystem in 0 superblock

The same with a manual fsck:

# fsck.f2fs -d9 /dev/block/mmcblk0p8

Can't find a valid F2FS filesystem in 1 superblock

Why is f2fs so damn old? F2FS-tools: mkfs.f2fs Ver: 1.1.0 (2012-11-29)

Is there any Recovery with a recent F2FS? Is there any f2fs static build for Arm? How do all the people format there /data with f2fs?

No wait, the block device is not readable by twrp_tf300t_kang_2.8.7.2.img. However after rebooting to official the block device was still missing but rebooting again to official it is there again.

Hi guys

i'm the happy owner of a TF300TG....but I use it as a TF300T ( T and TG are quite similar except the sound chips)

My bootloader is 1O.6.2.11 when BL's for TF300T are 10.6.1.x

as of today, my TWRP version is 2.8.5.0. but trying 2.8.7.0 hangs my tablet ( laoder unrecoverable error )

back to 2.8.5.0 the tablet seems to run normally

Well, I flashed it first from inside the previous TWRP (2.8.7.0 I guess?) and it didn't boot. So I reflashed it using your fastboot method and it fully works.

TF300TL with Asus stock rom 4.2.1

If coming from Asus android 4.2.1 (JOP40D.WW_epad-10.6.2.10) on a TF300TL (with LTE) and opening the bootloader, first the installing of TWRP recovery seems to be necessary.

BUT:

Which old TWRP version covers 4.2.1 JellyBean?

There is a hint at http://www.teamw.in/project/twrp2/97/ :

"If you have updated to the JB OTA bootloader then you must use the -JB version of the recovery, flashing the non -JB version could potentially permanently brick your device"

And which TWRP version is necessary for installing latest version:

KatKiss-5.1_TF300T_030.zip	* 2015-10-13 09:07 * 194M

LTE support is still not working?

OK. Here's my 2 cents forth of input. I downloaded TWRP 3.0.2.0 and installed .IMG from TWRP 3.0.0.0. Got same bootloader message as you. Rebooted to ROM, and used terminal commands to install KANG TWRP. Rebooted to recovery expecting same bootloader message. To my surprise booted right to TWRP. Rebooted back into ROM and used terminal commands to install 3.0.2.0. Rebooted to TWRP and low and behold it was TWRP 3.0.2.0. Just my experience. Didn't have to go back to stock or anything.
[Transformer TF300T Android Development] [GER]Roxxor:
Hm. ok... For me fastboot did not succeed on flashing the recovery to staging or recovery anymore.

But as you also experienced issues, it is obvious that the "flash .img" function is bugged. So I do not advise anybody to use it.

The problem about official TWRP is, that there is no maintainer. So I would not trust updates, but rather stick to tested recoveries. (If no newer recovery is required by the ROM)

I have a TF300T that I flashed to KM 6.0, seems to be running perfectly fine no glitching or reboots etc etc. I went about it somewhat different than the instructions, this I am sure of because I used TWRP 3.0.2-0 (not KANG TWRP) which I thought did not flash, but to my surprise showed up as my recovery anyway. Long story short here, I am not sure that my file system got changed to f2fs. Is there a way to find out via TWRP? Perhaps a comand line from the TWRP Terminal located in Advanced?

Thank you in advance.
[Transformer TF300T Android Development] gc2712:
Just open a terminal in a normal boot of system. Type

And check the output. Several partitions listed. Find /data and it will list if its ext4 or F2FS.
[Transformer TF300T Android Development] ImaPoBoy:
Thanks again for your quick answer. :)

Not f2fs but ext4 ... also I guess things are not as great as I had hoped, even though the tablet is running excellent, I do have a few issues.

no f2fs

Finding boot image, Boot image: not found, aborting.

No SuperSu binary, ... tried manually to reflash and update etc is when I noticed the no boot image found error

of course no more root.

However, despite these issues the tablet is performing well, a bit odd I guess.

At any rate, I suppose I will have to install the old JB 4.2.1 setup and do everything again to fix the issues. .... geesh but it seems to run so well I hate to do that lol.

Geesh, while not a pc noob at all, noob I am with these little green androids. lol
[Transformer TF300T Android Development] ImaPoBoy:
Ok, been debating this all day. Since my tablet is running (what seems to be) flawless and faster, should I even bother with re-flashing the original rom and redoing the KM 6.0.1 install?

Or should I be looking for the missing items to come back and bite me in the arse, if I leave it as is? lol

Is there actually a faster and smoother running "stable" custom rom other than KM 6.0?

Also, I do have the TWRP recovery I made still on my ext SD, if I flash the recovery will it return my tablet Root and SuperSu?

Sorry, for the noob questions, but we have to learn someway I suppose.
