[Q] SM-T807 Custom lollipop rom

Hi guys, i just switched my note 10.1 2014 edition with tab s t807
As usual immediately rooted my tab and try to flash a custom rom.
But now i have a problem,
samsung sends 3g tablets with a different serial number to turkey (where i live) than other countries, like my note tab was P602 when the other 3g notes was P605. But i was able to flash P605 custom roms to my tab.
Now i flashed a kitkat based t805 custom rom to my t807 but when i try to upgrade to lollipop i cannot flash T805 roms, altough t805 lollipop bootlader does not work too.
Now the question is do i have to wait to get a lollipop update to my t807 (which can take real long time) or is there a way to flash t805 lollipop rom.
Thanks for the answers...

You need the lollipop bootloader. Without it it's pointless to flash Any lollipop roms.

Ok i know i need lollipop bootloader but there is a question, international 3g version is called t805 but mine in Turkey is called T807, every spec is same but t805 bootloader does not work both on odin and twrp,
Should i wait for t807 bootloader or am i missing something

Unfortunately some of the carrier versions need a specific boot loader. So unless you try all the different t807 lollipop builds, you might get lucky, if not you may just have to wait.
Is your device rootable?

Hi,
SM-T807 is the 3G version while SM-T805 is the LTE version (or so called 4G. It is simply not an international 3G as you've mentioned). So their hardware is different. Both CPU / GPU and WAN modules are different and firmware is not interchangeable. As far as I know Samsung did not release Lollipop for T807 (3G). I doubt that the'll be releasing a Lollipop version anytime soon.
Cheers,
K.

Not sure where you are getting your information, but the hardware specs of the Exynos t807 are the same as the t805. The t807 is the carrier or region locked version. There are stock lollipop roms available for the t807. There may be slight differences in the modem hardware depending on region, but both can support LTE .
There is a snapdragon version which is what I think you are referring to, but again this can also support LTE and Lollipop is also available.

Hi, You're mostly right. They are both capable of using LTE DATA. This week I laid my hands over a T807 and unlike most marketing sites quote it has LTE functionality just as T805. But it seems that T805 also works as a GSM phone. T807 allows data only GSM access. So the difference is not about carrier locking. I am not sure if there's a hardware difference between the two at this point. But other treads on this site say T805 boot partion won't work for T807. So there should be some difference. Earlier Samsung tablets with GSM data only configurations could be upgraded to the GSM phone functionality. I've also come across with some news sites reporting that some carrier locked versions of T807 started to get the Lollipop update. I hope the regional ones would get this update soon.

Nope still waiting

I'd be willing to bet one of the recent custom roms will flash and work on your device as long as you flash the correct bootloader.

Of course it will work but the thing is i cannot find the RIGHT bootloader for my t807.
On kitkat i use t805 iron rom but i need exact bootloader to upgrade any custom lollipop rom.
I will be more than glad to anyone who can find the right bootloader.

What do you mean the bootloader doesn't work, does it even install?

You have N910P and its an CDMA hardware based device not GSM like N910F/C/H/G/T/A ETC.
Only N910P & N910V are CDMA models and all over the world the CDMA network LTE only works in usa and very few countries so dont hold your breath on it it's impossible you can only get 3g/hspa and since LTE will not work you will never be able to use VoLTE even if you root of change roms or even unlocked bands the LTE bands are CDMA based.
you need GSM based LTE device because in india all the networks are GSM based there's no CDMA tecnology exist in asia at ail
I know its frustrating so my best suggestions will be swap or sell it and get any international GSM model.

Not even if i flash a custom ROM that are made exclusively for SM-N910G by changing kernel?
Or by flashing stock firmware of N910G model or t-mobile's model N910T?

Answer is No if you read my last reply carefully i said it's an hardware difference not software.
Dont try to flash stock firmware from other models you can brick your phone completely.
Only way is replace the motherboard.

So is it possible to change motherboard and i can switch my motherboard with N910G model,
That would enable all 4G LTE bands of N910G model in my phone?

Try this rom this rom has GSM support and it will remove CDMA stuff from your device and replace it with GSM but i am not sure about LTE will work.
Download the rom and GSM FIX files then you have to flash TWRP recovery and flash the rom+gsm files from TWRP.
Give it a try and let me know.

In this thread OP has said 4G won't work even on his phone..
So may be this ROM is also of no use to me if i can't get 4G, anyways thanks for your support.

Your 4G CDMA radio can NOT be flashed to different LTE bands..the oscillator wont allow that much drift in frequency..like the other posters have mentioned, you will most likely have to get a GSM model of the N910..I honestly wouldnt try to swap motherboards cause that is just welcoming more headache. Sell yours and get a GSM model, everything can/will work with that. Best of luck

Flashing a different ROM variant. Does it work?

Just wondering if it's possible to flash a different ROM variant on the Honor 7x. I have a US variant (BND-L24) and it's bricked. There is no stock rom for it as yet so want to try either the BND-L22 / BND-AL10. Will this work?

I have the same doubt

It won't support the network bands in your Region but I think other software features might work . I'm not sure though

I would just wait it out. Honor US customer service says mid-March release for firmware, so it should be dropping any day now.

Can you flash US firmware on Korean or Chinese s20?

I ordered a Korean S20 ultra (988N), but live in the US. Has anyone flashed the US firmware on a bootloader unlocked SD variant of the phone (ie 988U1 firmware on a 988N or 9880)? If so, did you have to change the CSC to XAA before or after you flashed the firmware?

I don't have an answer to your question but will the non-US phone work in the US like on Verizon system as is?

It should work fine on LTE. The main Verizon bands are 2, 4, 5, 13, all of which are supported in all s20 variants. I don't think you'll get 5g on any US carriers, so if that's important, better to pick up a US spec phone, and pay to unlock the bootloader.

I tested the phone (G988N) on both Verizon on TMobile. I was able to get 5G on both carriers. So I can confirm that all features (except possibly WiFi calling on Tmobile), work.
So using the KOO firmware in the US works perfectly fine. No reason to try to flash XAA.

I wish you had tried lol I'm tempted to flash the U1 firmware on my Korean S22 Ultra but I'm looking for more info before going for it. Still no luck.
