HI All

Firstly, long time read of this forum/app, first time poster. Flashed a number pf phones/tablets over the years since i first flashed my Windows HTC HD (?) to Android Gingerbread. Forgive the details there, it was a long time ago and I could be slightly wrong.

In any case I usually have no problem following the odd customer rom flashing guide or rooting guide, etc and generally get done what I need to,. However after a few late nights and admittedly having not flashed anythign for a couple of years I am really struggling to flash my t320 with anything!

I cannot seem to flash TWRP so I am coming to te conclusion the bootloader is locked. I have read around and it seems as though it shouldnt be locked or I should have an OEM Unlock option in developer options - I do not!

I have managed to root it though using Odin and the CF Auto Root but if I try runnig TWRP app to flash TWRP or Flashify to flash a lineage ROM I do not seem to get anywhere. It just boots as normal with TWRP and I dont get any TWRP in recovery mode. Flashify result in a boot loop so I had to reflash the root to get it to boot,

When I enter into download recovery mode the following shows on the screen:

ODIN MODE
PRODUCT NAME: SM-T320
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
QUALCOM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T1, R1, A1, P1
WRITE PROTECTION: Enable
UDC Start


I am hoping someone can dicipher this and tell me what the problem is. Clearly it looks like somethign is securing the bootloader.

Oh yes and this is the UK WIfi model running stock Kitkat 4.4 (updated as far as I can get it OTA)

Thanks in advance
 
@radioshed I've flashed my T325 again not to long ago, after I had to return to stock. So I know bootloader isn't locked.
Did you take care to boot directly into TWRP after flashing it via Odin?
If you let it reboot automatically the stock recovery gets reanimated.
Uncheck "auto reboot" in Odin and do it manually.
I never use anything else but Odin and read that TWRP app isn't recommended to use.
Know nothing about flashify.
Rooting stock isn't necessary as you're going to flash a custom ROM anyhow.

Rather than using Odin to flash TWRP and then that for a customrom, can I just use Odim for the rom?

If so which box do I use in Odin?

Thanks for your response btw

Which file did you take and where from?
I have the cf auto root for the t320 which I downloaded. That worked tho

I got the tar file for TWRP from the TWRP website, the apk too.

I've tried both to flash the TWRP recovery but I still seem to end up with the original recovery screen

After flashing turn it off and reboot with button combo.
Perhaps you were not fast enough when rebooting directly after flashing. I sometimes need to flash TWRP several times.
You've put it in "AP" didn't you?

Yea in the AP section. Auto reboot off.

Boot straight into recovery. No change

OK So i have some more details...still no change here though unfortunately :(

I have just tried a few TWRP flashes using Odin 3.09 but also tried 3.14.1 and 3.10.6 for CF-Auto-Root-mondrianwifi-mondrianwifixx-smt320.tar.md5 which does work

I have tried flashing the following files from https://eu.dl.twrp.me/mondrianwifi/:

twrp-2.8.4.1-mondrianwifiue.img.tar
twrp-3.1.1-0-mondrianwifiue.img.tar
twrp-3.1.1-0-picassowifi.img.tar
(not sure where i got this one from)
twrp-3.5.2_9-0-mondrianwifi.img.tar

not sure what else to do but cant get rid of the download recovery screen :(

After flashing around that much it might be helpful to return to a clean system/device by flashing multiple part stock ROM via Odin and then start again flashing just TWRP without CF prior to that.
picassowifi is the 10.1" tab btw.
I'd stick to 3.09 until TWRP is flashed as I know it worked on mine while having stock.

Thanks pal, I tried that last night, flashed back to stock 4.4.2 using Odin 3.09.

Altho the download I found for it only seemed to have one tar file. Not sure if I need a BL tar too.

Still no dice tho dammit :(
