Lenovo Tab7 HD TB-7504X - Update to Android 8? - Thinkpad Tablet General

Hello,
a friend of mine owns the mentioned tablet in the subject. As we want to use both a specific app (Skydemon) on our tablet, unfortunately now it seems that this tablet is not compatible with its version 7 of android with this app (other tables are working fine with android 7 and skydemon), I am searching for a custom rom. In my opinion lenovo itself does not offer any more uprades to this tablet. Is tehere really also no custom rom available for this device?
By the way, what exactly is version 7504X? Is it a Tab7? Tab3 7? Tab 4 7? Lenovos name convention is really confusing for me ...
Cheers

[Q] TWRP recovery for Tab 4 10.1 , when ?

Dear developers!
Let me ask you when will the normal operating recovery*? Really for our device is harder to do than to Tab pro or Tab S ? For them, a long time ago is made and people enjoy , doing firmware, mods , etc.. Why do we so hard? Device on sale for six months, and as a result only 7.0 Table 4 recently received from the TWRP developers full recovery*. When can we expect for us?
With deep respect .
Wondering this too, I just picked up this device but I'm thinking of just returning it to get a nexus 7, as I'm not sure if this device will see L or not :/
I'm wondering this as well. I have the SM-T530NU and this thing is super nice. the hardware specs are great and with an uncrippled android os and kernel that supports overclocking it would be unstoppable. How does one go about building a proper TWRP for this thing?
If you look at that TWRP website, notice that there is a listing for TWRP 2.8 - Galaxy Note 10.1 (2014) Qcomm, thats very close to what we have. What is your guys model numbers? We need someone to look at the Galaxy Note 10.1 (2014) Qcomm TWRP and see if we could modify it easily to work on the Tab 4 10.1

Yep, I'm actually thinking of returning this device though, as I was hoping I would be able to put custom roms on it (I don't want to be stuck with Samsung's stuff.), but if TWRP is possible for our device, then that means custom roms will eventually be a thing for this I hope.

all we need is someone who has one and knows how to make android. I'ts not too bad rooted and the samsung crap taken off of it, but i agree with the custom roms statement. we need some custom roms. Cyanogen, AOSP, Beanstalk and id be happy
apparently there is a SEMI-working recovery available. Also the source for said recovery is available also. so we have a decent starting point

Hey I'm in the same boat with the clone of your device called the Asus Trio TX201LA. The memo pad shares the same 4.2 rom, same IFIW, Same soc, same droidboot version etc etc. Basicly its just got an all alluminum case but same exact tablet. Mine can run ME302c ROM but camera and doc support is lost. I am working on a rom using BLISS. If you are still looking to update PM me. Perhaps we can work on this together.

Team Bliss is a lil less helpful then I thought they would be, I have had little to no guidance being a noob. So unfortunately I have not gotten it off the ground, nor would I be able to with a locked bootloader anyway. I still use the windows half of the tx201la nearly daily as my main machine and love it. I wish the android could be updated and the me302c shares a lot in common. I have asked asus to look into offering unlock because that would allow me to test a lot of builds already available like the one made for the galaxy tab 3 10.1 which shares the same soc and may possibly boot up on my tablet and even the me302c. If we pester asus to release an unlock tool like they have for just about every single zenfone 2, 3, 4 and 5 (all the older zenfones have the same intel soc family) we are half way there to getting a rom since there has been so much development for this soc already in the zenfone and galaxy tab 3 10.1. Asus is somewhat required to give us something since the atom z2560 is susceptible to the spectra variant 3 (newest called next gen) and if they offer any sort of update it would be an upgrade for us. It maybe advisable to start a petition to get this done. Would you want to try that route, we need unlock first and foremost and its most likely we can convince asus to do that with enough signatures or a small claims lawsuit even. thoughts?
Hi guys, We all have the same issue, a beutiful "still" working tablet with no support.
I read several people asked for a petition or to pay a dev to work on a rom.
If you all are thinking it is worth we could **** how many people around the world
Have still this tablet, or should I open another topic?

Lenovo Pad 4 7Inch roms and root

Hi folks I have just bought my self a TAB 4 7" Tablet. ( Lenovo TB-7503F )
The main focus of the tablet is to be installed as a carputer in my RX8, however I am wanting to see if there are any custom roms, root etc before i finish the install, I have searched for it everywhere and its almost as if it doesn't exist.
Could anyone point me towards some if they are available.
Thanks in advance

Galaxy Tab 4 "Value Edition" (SM-T533, matissevewifixxx)

Hi everybody,
I've been looking up and down in this sub-forum but can't seem to find an up-to-date ROM (Nougat or up) that seems to be suited as a daily driver for the Tab 4 SM-T533 "Value Edition" (WiFi only, no LTE). I understand it has a different SoC than the regular Tab 4, hence the ROMs available for that one won't work.
Does anyone have a recommendation for a good alternative?
Currently, I am still on Stock Android 5, rooted (with SuperSU) and TWRP in place. So, I'm good to go, just need a decent ROM.
Thanks for any hints and tips!
Cheers
I have the Tab 4 10.1 wifi only edition t530 and there are craploads of roms. Old but still available. Most don't have working camera. I'm currently running a Dual Boot setup where Stock is my primary rom and LineageOS 14.1 is my secondary rom i can boot into whenever I'd like. Pie has also just been released for this device.

Thanks for getting back. Also for reminding me that I forgot to mention the model name. I edited the OP to point out that it's a SM-T533.
Now, the trouble is that the SM-T533 and the SM-T530 supposedly have different hardware so the ROMs for the 530 wouldn't run on the 533.
I'd be happy with Nougat already. Wouldn't even need to be Oreo or Pie.
Too bad, but it seems there aren't enough devices out there so that it would make sense for any developer to spend the time porting a ROM to the SM-T533.
Cheers
Are there any otheres out there using this variant, at all?

Hiya
i acquired ex demo model of the tab4 T530 and T533.
i managed to fix the T530 model flashing with Odin but no joy on the T533.
what i noticed is the the firmware for the T530 had BL CS and AP files ,but the T533 are only i big file, @Poorusernamechoice developer was supposed to break the firmware into AP BL and CS but alas i have not heard anything back , please assist anyone who has the know how
@musafir 7 Thanks for your reply. I don't believe that after two more years chances have become bigger that anyone puts a minute of work into this. :-( By the way: We still have the tab and it's still running, though it's being used only scarcely now.

Yoga Smart Tab

Hello,
So I got a Lenovo Smart Tab (yt-x703f) and really want to flash TWRP to it, so I can flash LineageOS rom, but it seems like there's no support for it, or even a subthread on XDA.
(I tried various twrp images)
Anyone got some experience with that tablet and have something working?
Cheers
For some reason this device gets the silent treatment on all fora. I can't figure out why, this could be a great multimedia device with some adjustments. batt life is great as is the sound. Screen is ok ish and the speed needs to be tweaked, but no one is willing to tweak
You can root the device and even flash a GSI on it. Tested myself and everything is working
Yoga Smart Tab - Iron Grey​Part Number: ZA3V0005US
Not sure if we are talking about the same device but lenovo does not support their mid tier devices with OS updates and would like to install a bloatless OS also pie is really dated and wondering if i will run in to issues with app compatibility. There is also that issue where it won't run HD in netflix because netflix is a static app and can not be removed and reinstalled. Hence bloatware and would love a clean google experience.

Flashing a GSI might help if the device supports Project Treble. Basically any device launched with Android 8 and above should support Project Treble.
Hi, I have a Lenovo Yoga smart tab (YT-X705L) and I want to install a new rom on it. I’m not an IT wizard so I need help with that. Would you find anyone who can give step-by-step instructions from start to finish with download links.
And if you can find experiences on how anything works (which is GSI). Thanks in advance.
