[ROM][SM-T900] CyanogenMod for Tab Pro 12.2 SM-T900 (v2wifixx)

[kb8no]

I finally rooted my t900 with the UE firmware. I'm preparing to install CM. I installed TWRP 2.8.7 tar wifixx from a TWRP download using Odin which worked fine. Then I tried to flash all three of the TWRP 3.0 versions and they all boot looped. Anybody else had this experience? Seems odd that the official TWRP builds don't work.

My apologies if I didn't find what I was looking for. Is there a thread with instructions how to install TWRP on T900? I only found some videos of people already running it. Anyone willing to point me in right direction?

I was struggling as well. See my post 2 above yours. I figured it out today. Most of what you can Google for rooting and installing the custom recovery TWRP is from ROM's before Lollipop and my device came from EBay already with the Lollipop OTA installed. This T900 unit is called v2wifi but there are 2 main firmware variants, v2wifiue (North America) with firmware T900UEUBOJ1 and v2wifixx (Europe) with firmware T900XXUBPA1. It makes a difference which firmware you have. Since my OTA came from the US my OTA had the UE firmware. I was able to use CF auto root with Odin for v2wifiue. However, TWRP only has a v2wifixx version. I found that 2.8.7.0-v2wifixx worked with UE even though it was the wrong version but that 3.0 boot looped. I could only recover from the bootloop by using Odin to install the UE firmware again.

Then I thought that maybe the problem is that UE is non-standard and that XX is the standard firmware. So I got back to UE with TWRP-v2wifixx 2.8.7.0 where I was before the boot loop. I did a complete wipe and used Odin to flash the XX firmware. Then I used CF auto root with ODIN for the v2wifixx. Everything worked so far. TWRP has a 2.8.7.0-wifixx offered as a tar (all the 3.0 are img onlly files). So I used Odin to flash 2.8.7.0-wifixx. I then booted into TWRP and used TWRP to flash the latest 3.0 img.

BAM. JOY. T900 with v2wifixx firmware, rooted with SuperSU, and with TWRP 3.0. Grab the firmware from Sammobile, TWRP from their download site, and CF auto root from his site. It goes without saying to have USB debugging enabled., never to allow TWRP to install Super User, and allow TWRP to modify the system.

Now, if someone could explain to me why we need a P900 TWRP to install P900 CM 13 I could be much smarter than I am now. I can't see why the T900 TWRP 3.0 v2wifixx version wouldn't flash P900 CM 13. I want to try CM 13 next. Anybody?

the tablet is on 5.1.1 with build number: LMY47X.T900UEUBOJ1. I am assuming it's running EU firmware.

EDIT: when I flash TWRP and then I enter recovery mode it always goes to stock recovery for some reason. I'll try CF AUTO root then flash recovery w/ root and TWRP app.

No. UE is the North America firmware as I said in my post. You need the XX European firmware. If you are not rooted you cannot install a custom recovery (TWRP). You must use the correct CF auto root for your firmware. I advise you Odin the XX firmware and then Odin the v2wifixx CF auto root. Then you can install TWRP 3.0 for v2wifixx however you want to do it. Read my post carefully.

BTW, I'm now using Tapatalk on CM12 to type this message on my T900. Autorotate is working fine, I was expecting a problem. I have had a few crashes with reboots as people have described but it seems to be leveling out and I haven't had enough to figure out what triggers them. I'm pretty excited.

This is the way I did install TWRP. Use CF Auto Root and then flash TWRP. But it's giving me error executing update binary in zip.

is TWRP 3.0 needed to flash? i installed 2.8.7.1 but i'll try 3.0 now.

humm... 2.8.7.1 works. You don't need 3.0 (but you want it) so don't mess with it now. Did you Odin flash the XX firmware from Sammobile? Where do you get the execute binary error, in Odin? I did one thing at a time and then booted into ROM. 1. flash XX firmware 2. flash CF auto root. Get that to work first. Open SuperSU after you booted from CF auto root. Do you now have a rooted ROM? (Worry about TWRP after you have these accomplished.)

I get that in TWRP when trying to flash the rom. And no I didn't install the EU rom. I just did it the current one (yea I know I read what you wrote) if TWRP 3.0 won't work i'll do that, you mind giving me link to the firmware that you used from sammobile?

Well, to the best of my weak abilities, if you don't care about TWRP 3.0, the TWRP 2.7 should work even you are installing a v2wifixx TWRP on a v2wifiue ROM. I'm thinking these two ROM's have slightly different kernels which is why they need different TWRP and CF auto root (as close as they are). I did not try go install CM12 until I figured out the XX ROM and installed it and then rooted it with the CF for XX and installed TWRP for XX so I can only guess at your problem. Just Google sammobile, it's the first hit. You have to register for an "account" for free and free takes an hour but the price is right.

I'm like you, since the TWRP 2.7 for xx doesn't boot loop and appears to work it should be able to flash CM12. Heck, the guys are using a TWRP from from the P900. But I can only tell you what worked for me and make assumptions. I do not find any of this discussion we are having anywhere so I hope somebody else reads this and benefits and adds some knowledge.

I do assume you booted the ROM and opened SuperSU before you tried to flash CM 12 and you wiped in TWRP before you installed.

Hmm yea i'll play around with maybe a TW modded rom and see what happens. I will also try TWRP 3.0 and let you know how it goes.

Thanks for your time! i'll get back at you.

I bet if you do some looking in the P900 thread, I bet you can find something.

I'm using the P900 RR rom but last update was July 11, 2016 and jdelano has said he's not doing anymore builds

Apologies in advance if a tad off topic.

My Tab Pro 12.2 developed screen flickering when at 60 - 65%, took to Samsung support site who after 10 days told me it was a screen problem, more worrying they said they had no replacement parts to fix now or in future & I was offered a refund of purchase price or another model (I choose the new 813 tab 2) which is great *but* really miss my 12.2 screen, has anyone else heard of no more 12.2 screens being made or available please?

Shalom & many thanks, john

you don't need a twrp from the note to install the note rom on the tab. all that needs to be done is to edit the updater script in the note rom so it doesn't check the device to see if it is a note and fail bc it is not the correct device...

This explains a lot. Thank you. How exactly do you find and modify the updater script?

sounds to me like you have the battery connection problem. search around the site and you'll find a potential fix.

Many thanks but too late for me. They kept it and as I said gave me a brand new T813 as a replacement, just a tad concerned they claim to have no spares to repair the screening my 12.2 Pro (they claim was the problem).

Many thanks anyway.

Shalom my friend, john

open rom in 7 zip go to meta/google/look for updater script pull to your desktop. get notepad++ and open is look for a line with device check ex p900 and delete the whole line. save the updated script then delete the current one in the open 7 zip of the rom and then drag your edited one there.
