😂😍

Hey I'm getting slower in my old age. Last time I rushed on a ROM I fell and broke a hip. Haven't been right since . Ok the hip part I made up but old age is creeping up. All jokes aside I'm making good headway. I ended up taking the original port ROM and laying it out fresh on the drawing board. I was running into unforeseen issues due to the ports and mods that were done previously. A port ROM is much akin to a hobby go-kart you might find at a flea market or yard sale. It's a collective montage of tweaks, mods and alterations performed by everybody who has owned it. Shortcuts are made and corners are cut. It's called a dirty port for a reason. 😉

Im still at it. @limited_imagination has graciously offered his hand in assistance on this project. He is an official code compiler now so his offer will benefit the cause no doubt. He recently compiled LOS 17.1 for the Mi Pad 4 from source code. Anyway friend good to hear from you as always. Oh, the refunds have been sent out. You know the old saying...the check is in the mail. 😛 Hold your breath and keep watching that mailbox.
[Android General] Viva La Android R.I.P.:
Gents I am finally back and proud to say I do have something fresh and new for our beloved Tab3. I have ironed out an up-to-date TWRP custom recovery, bringing the code base up to 3.2.1-0 with full theme support. I'm posting it now and will post a link here as well once my thread is done.

So without further ado, an updated TWRP build with a fresh new look. I have more treats to come for the Tab3 8.

Thanks for this! If you wouldn't mind, I'm trying to create an archive where people can download various files and guides, so it isn't relying on a company or google drive account that could be taken down. Heres the link: https://github.com/TheRealGramdalf/xda-archive
[Android General] Viva La Android R.I.P.:
That is splendid. Feel free to do so with my blessings and thanks. I have a couple of different ROMs baking as well so it won't be long on those either.
[Android General] Gramdalf:
Awesome! I'm a bit busy at the moment, but I'll get around to it eventually. If you wouldn't mind promoting this when you see fit as well, that would be greatly appreciated. In order for it to be really useful will require lots of participation - and I can't add every single android device by myself.

Thanks again!
[Android General] Gramdalf:
Also one last thing.

I tried this on my lenovo yoga tab 3 850f, but it didn't work. I recall having this issue before - I had installed twrp succsessfully, but I must have enabled modifying the /system partition because it locked in a bootloop. I used the LMSA tool from lenovo to restore it fully, and am now in the process of reinstalling twrp. I remember installing 3.2, not the latest 3.6 version correctly.

Here is my issue:

On linux (fedora 36) adb doesn't work (insufficient device permissions, even though usb debugging is enabled). Fastboot seems to work (with sudo only however), but I'm not quite sure - the device ID is 0123456789, not anything SN related. That and the fact that 'sudo fastboot flash recovery twrp.img' works but 'sudo fastboot boot twrp.img' does not.

On windows, adb works just fine, but fastboot doesn't. No devices appear, even though the tablet is clearly in fastboot mode.

After flashing the twrp.img to the recovery via linux, booting into recovery (at all) doesn't work - the normal bootloader/recovery is gone. So fastboot must have worked to some degree.

Also not related to my issue but one thing I found super helpful was the lenovo official recovery assistant - it did a fabulous job of resetting my device without the ability to boot into anything (didn't require twrp or fastboot or the bootloader/recovery, just hold the volume plus button and plug it in - no power button involved).

This isn't for the Yoga Tab 3. It's specifically for the Lenovo Tab3 8 TB3-850F or 850M. The Lenovo Yoga Tab series is an entirely different series.
[Android General] Gramdalf:
Ah. That would be why. I thought tb3 was an abreviation for tab 3. Do you happen to know offhand a guide or something that would work?

Edit: I remember it was by SevenMaxs, but I can't find the download or thread related to it.
[Android General] Viva La Android R.I.P.:
Sure thing @Gramdalf. I'll take a look and see what I can dig up for you. So what is your exact model number for your Yoga Tab 3?

You're not the only one to get the two confused. The model numbers are too similar, as are the series names. Lenovo slipped up on the nomenclatures on those two devices.

Here is a thread on rooting and custom recovery for the Yoga Tab 3 /YT3-850F.

https://xdaforums.com/t/guide-lenovo-yoga-tab-3-8-yt3-850f-how-to-unlock-and-root.3597293/

This build of TWRP should be compatible with your tablet as well.

[Android General] Gramdalf:
Awesome, thanks! My model is the yt3-850f. I'll try this and see if it works. Thanks a lot!
[Android General] sandyiscool:
Waiting eagerly for these ROMs to breathe new life into my tab3 850M. Thanks a lot for taking interest in keeping this device alive with custom recovery and ROMs :)
[Android General] Viva La Android R.I.P.:
The ROMs I'm working on are for the 850F. Because the 850F is WiFi only, the ROMs I'm working on won't have the radio interface layer or telephony support for the 850M. And, the 850M has a different chipset platform that than the 850F. Luckily TWRP works on both due to dual kernel implementations and the similarity in the two chipsets.

Have you tried the 7.1.2 Resurrection Remix ROM for 850M? The Russian devs over at 4PDA ported it and it is said to be very stable.

If you haven't tried it, this is a download link.

ResurrectionRemix v5.8.5 TB3-850M
[Android General] Gramdalf:
Do you know of any ROMs for my specific model (YT3-850F)? I've looked around, but I can't find one.
[Android General] Viva La Android R.I.P.:
The Lenovo Yoga Tab 3, unfortunately, did not receive development attention from the custom Android community. The only possibility I know of in the way of custom ROMs is 4PDA, which is a group of Russian devs who are partial to Lenovo devices. I can check with those guys, but otherwise I know of no custom ROMs for the YT3-850F.

My tentative search indicates that 4PDA does have a forum dedicated to the Yoga Tab 3. You will need to use Google Translate on a PC web browser unless you speak Russian.

Mod edit: 4PDA link removed.
[Android General] sandyiscool:
Sorry for the late reply. Was unwell for sometime.

I had tried out the well known LOS - Android 7 rom for 850M which again I got in some post in this forum a few years back. The performance was terrible.I had not tried out this RR rom at that time.

After you shared the above link, I got interested and set out to flash TWRP on my tab. Turns out I may have soft-bricked it ;) The device stays stuck in the initial Lenovo logo.

I have left it at that for now, due to lack of time. I may revisit it sometime later to recover using SP flash. I guess by that time if the ROMs that you are working on are available, I would like to test those too. I do not use telephony on my tab and if everything else could work fine on 850M, even if the rom is for 850F, given their similarities, I would be happy. I would mostly use the tab to browse and read, with occasionally trying out some apps.
[Android General] Viva La Android R.I.P.:
I recommend using the Lenovo-Moto Smart Rescue Assistant to recover your device. It downloads the most recent firmware directly from Lenovo's software servers and flashes your tablet in BROM mode, via a powered off state. The tool is for Windows and can be downloaded from Lenovo's support site here https://support.lenovo.com/us/en/downloads/ds101291

After you get restored, let me know by posting here and I'll assist you in getting TWRP installed and working .
[Android General] mrcraft512:
Hey, I know this has been asked before but are there any custom roms for lenovo yoga tab 3 8 (yt3-850f)?
[Android General] Viva La Android R.I.P.:
The Russian developers over at 4PDA have a Lenovo Yoga Tab3 forum. Those guys have done some amazing custom Android work on a nunber of Lenovo tablets and smartphones.

Unless you know Russian, you'll need to use a mobile browser that translates the page to English (or your lamgiage of choice). There may be a custom ROM available there, TWRP builds, etc.

Hello, recently I recovered my tablet to stock room after being for almost 2 years bricked because of a malicious rom file.

And now i want to go back to custom os's, but i have a problem, after rebooting to bootloader with adb when i do >fastboot devices it doesen't show anithing, could someone please link me to the fastboot drivers? thanks in advance!
[Android General] Viva La Android R.I.P.:
What is your tablet showing up as in Windows Device Manager? You likely already have the drivers. It's a matter of updating & configuring them.
[Android General] TheTalkingGrasshopper:
As an "MT65xx Android Phone" under "libusbK USB Devices"
[Android General] Viva La Android R.I.P.:
Install this, run it, and select Y(es) on every prompt. It should resolve your issue

File on MEGA

mega.nz

It installs ADB, Fastboot and USB device drivers.

If it doesn't fix fastboot recognition for you, let me know and I'll walk you through the manual setup.
[Android General] TheTalkingGrasshopper:
Thanks, but after downloading it, double clicking it and giving admin permissions it does not launch, am i missing some requirement?
[Android General] Viva La Android R.I.P.:
Go back to device manager on Windows. Right click your tablet and select update driver. Tap Browse my Computer then ..pick from list. Then look for Android Device in the list. Next select either Bootloader Interface or ADB Composite Interface and install the drivers

after flashing twrp.img to recovery my tablet now freezes at the lenovo logo. my laptop wont recognize it correctly and now calls it "MT65xx android phone" ... minimal adb and fastboot can't see my tablet as an adb device, so I don't have a way to recover by flashing the boot and system images. Someone please help me fix my tablet.

Update:

I was able to get adb to see my device, but it now displays as unauthorized. I had set the tablet debugging to remember my laptop but it still freezes at the Lenovo logo, so its not connecting in debugging mode anymore, and I don't have any way to boot the system...

Fixed: thanks for the post, thanks for everything you guys this is awesome.

I tried kill-server, start server but it still reads as unauthorized. I can't seem to find a way to get around this problem now. I got MotoJunkie01's twrp flashable stock images ready to go, now I just need to crack this adb issue. Any help would be appreciated.

hello! haven't posted in a long while here. I went Apple for many years. I used to have an xperia x10 (yeah it was that long ago...) and I flashed all sorts of roms on it but I guess I'm a little rusty here... So i did something wrong, and I'm pretty sure I know what it was. everything went fine up until i installed twrp recovery, after that it won't get out of the boot image. it wont go into any recovery mode (the OEM one or twrp) and it's just stuck on that orange lenovo image. I'm pretty sure what I did was that I accidentally installed the twrp. img on zip mode and not on img mode.. could that be it? how to I fix this? thanks and sorry for the long paragraph.

edit: when I try to boot into recovery mode using volume down+power, it just goes into the lenovo boot image, and my computer doesnt seem to want to recognize it in any way shape or form, so I can't use adb or anything... can this be salvageable?

After flashing recovery tablet is stuck on LENOVO screen.

I don't think I did something wrong. I succesfully rooted 10+ phones before.
[Android General] MotoJunkie01:
A bootloop sometimes happens after flashing the recovery partition and/or flashing a root script, for some odd reason. The big question is, did TWRP flash successfully, and if so, can you boot your device into TWRP?

As long as you can boot into TWRP, I have a thread with the stock firmware images for this device, which can be flashed via custom recovery, which will enable you to boot into the OS in full stock condition.
[Android General] MotoJunkie01:
Don't beat yourself up. Lenovo has rather confusingly dubbed a few of its tablets the "Tab 3." There is the TB3-850F, the TB3-850M, and the A8 variant you have just to name a few. There are also regional variants of those models. You're not the first person to have made this error by any means. Hopefully, you can flash your device back to stock condition.
[Android General] mt12345:
I simply returned to the shop and got replacement.

But Im not gonna try again to root it.
[Android General] MotoJunkie01:
Can't blame you there. Rooting always involves risk. Sorry you encountered issues.

[Android General] Shina1:
How do I do that? I got stuck at the screen too? I don't see any guide on it. I can get back to TWRP.

Edit: Saying it can't find device... Windows is trying to install device setup.

It gets stuck at the loading screen where it shows a grey loading bar. It won't go past that. I can't boot into TWRP anymore.

If it doesn't work, I'll just return it. Say it just stopped working or something.

Managed to get back in TWRP, somehow. Although, I keep getting back into TWRP. Could I flash stock recovery?

Tried that and I still get kicked to TWRP.
[Android General] MotoJunkie01:
Go to my thread with the stock firmware images. Download syatem.img & boot.img. Flash both images in twrp and you will be able to boot into the OS.

Here's the link.

Thank goodness it worked. So, where do I continue from there, or is it possible to start over?
[Android General] MotoJunkie01:
From there boot back into TWRP and flash the newest SuperSU v2.82 zip file. Note: reboot into the OS after flashing the root script can take several minutes, so don't interrupt it.

[Android General] Shina1:
Do I flash it to a specific partition?
[Android General] MotoJunkie01:
No. The zip file will not ask you to install to a specific partition like image files do. Simply install the zip, wait until flashing indicates complete, and reboot system. Again, first boot can take several minutes to complete.

The stock images from my thread are intended to be flashed either with fastboot or TWRP recovery.

[Android General] MotoJunkie01:
Sounds like your bootloader is still locked. Are you certain that you unlocked it successfully? To ascertain your bootloader's status, boot into fastboot mode, open a command window in your adb/fastboot directory, connect your device via the OEM sync/charge cable, and type:

fastboot oem device-info
