Stock boot.img for Lenovo tb-x8504f - Thinkpad Tablet General

Hi,
Does someone know where I could get the stock boot.img for Lenovo tab 4 8 tb-8504f? I'm trying to flash magisk under twrp, but I got this "Instal error 1" that is usually solved by flashing the stock boot.img
Thanks!

I posted an image, but it had been modified by magisk. Going to look for a clean image.

That would be great, thanks!

This is a twrp backup of the boot partition:
https://drive.google.com/open?id=1Ss4dvyOB5bH5cmfQGpoEe3O_LATunozD

Does anyone have a stock unmodified boot.img from a nougat TB-8504F device? If anyone has one of these devices can they pull one for me? I can provide instructions.

For onscreen navigation buttons you can download & flash s031(white) ota it will also work with gold version , but capacitive buttons will be disabled & only onscreen buttons will be enabled ,I know this because I flashed gold version ota on my white pixel v1 & capacitive buttons started working ! Yes this is true white version also have capative buttons and can be activated by flashing gold version's ota ,this is a little secret LAVA kept hidden from us :silly:
& as of porting cm 13 rom ,yes I can port from source but right now I don't have access to a decent internet and computer so I can't do it , its our badluck that second gen Android one have very little development going on at the movement bcoz second gen is divided in to both mtk & snapdragon chips , but if I find any mtk6582 second gen Android one rom ,I will try porting it .

[ZE550KL] Bootloader Unlocked - Still Can't install CM13

Hello, n00b here! so I am having this huge problem in my hands right now.
I unlocked my bootloader in my 1.16.40, after tons and tons of tries.
So after checking that everything was okay, I flashed TWRP recovery and opened it, however it constantly failed to install the latest CM13 version.
So, wrongly I decided to do an advanced wipe and get rid of everything on the internal storage, then I tried to install CM13 again and failed.
at this point, I obviously was stuck between TWRP recovery and Fastboot, which shouldn't be a problem.
Now I don't know what to do, I can't install CM13 because of: assert failed asus.verify trustzone (which I have no idea how to fix)
So, almighty XDA forum members, how can I install CM13 on my cellphone?
PS: forgot to mention I unbricked my cellphone by going back to 1.16.40, I couldn't install 21.40 or any MM version.
Question: Do I actually need to install 21.40 in order to install CM13?
You must in MM base firmware, than u can flash CM13... I think
Yes, you need to install 21.40 to install any CM 13 ROM built after June 14th. I had the same issue. I installed the Asus updates in this order to fix my issue.
- UL-Z00T-WW-1.16.40.763-user.zip
- UL-Z00T-WW-1.17.40.1234-user.zip
- UL-Z00T-WW-21.40.1220-1615-user.zip
- UL-Z00T-WW-21.40.1220-1794-user.zip
After the latest update is installed, you should be able to install CM 13. Hopefully this is helpful.

How to install cm13 give me instruction to do it
If you have a ze550kl, your version is z00L.
On the page https://wiki.cyanogenmod.org/w/Install_CM_for_Z00L follow the directions under "Installing CyanogenMod from recovery" to install CM 13.
If your install fails due to asus.verify_trustzone failures, you will need to update the phones firmware to 21.40.1220 before installing CM 13. My phone did not allow me to update to 21.40.1220 until I updated to 1.17.40. I couldn't update to 1.17.40 until I updated to 1.16.40. The firmware is available through the Asus website.

Error 7 can indicate multiple issues. It could be an incompatible ROM to your hardware. It could also be an incompatible firmware version to the ROM. My issue was incompatible firmware and I had to update it before installing a custom ROM.
Do you get an error similar to this when updating the ROM? "Can't install this M package (Fri Jul 22 04:15:16 CST 2016) L less than 20160426 build (Mon Feb 22 09:53:24 EST 2016)"

Check this
If you're running LP firmware it should fail saying that "asus.verify_trustzone" assert has failed.
In order to update your firmware to MM, you can either flash ASUS MM rom in stock recovery or flash a package that will update your FW using TWRP

BLU Studio 5.0 Ce D536 BRICKED!

I have a BLU Studio 5.0 C e D536 (MT6571) that's bricked; it won't turn on.
Originally started as a boot loop but after flashing a stock rom i got from needrom, it no longer bootloops, it's as if the battery is dead.
I used SP Flash Tools to do this.
Any help here would be appreciated.
Thank you.
I have the Stock Rom for the D536U from my unit. I was hoping for a LineageOS ROM to do it. More than likely ADUPS has corrupted your System Partition.
---------- Post added at 08:49 AM ---------- Previous post was at 08:35 AM ----------
Here is the thing. The BLU Studio 5.0 CE is the D536U, not the D536. They use different Roms. the D536 uses the MTK 6571 while the D536U uses the MTK6572.
The BLU Studio 5.0 CE is the 4 GB Variant of the 2 GB BLU Studio 5.0C.
---------- Post added at 08:56 AM ---------- Previous post was at 08:49 AM ----------
What I hope you haven't done is tried to flash the Preloader. See if SP Flash tools still sees the Device in Serial mode.
I too have a bricked BLU Studio 5.0 Ce D536 from a friend, it no longer boot loops, it's just off. What can I do to fix it?

Got working DUAL BOOT

Hey, i got working DUAL boot with my Win10 Yoga Book and Android x86.
But some functions in Android are still not working (e.g. Bluetooth).
But I am not a programmer so I have one question:
On Lenovo's Support page you can get the open source Code for Android. Is it possible to integrate this Code with Drivers etc. in the Android x86 Rom?
Thx

Better solution: use MSFT android remote desktop?
Waiting for my Android Yoga Book YB1-X90F to arrive, I figure using this app to remote into my laptop @home should work same as having Windows, except of course I'd have to be online.
Anyone care to report on how usable the YB1-X90F is when not connected? That would be my only concern

ResurrectionRemix to LineageOS

Hello guys, i'm looking for help to flash LineageOS into my phone, and as the title says i'm currently running a RR which got laggy and updates via OTA are not available anymore, someone was telling me i better downgrade to stock, and then flash a new build of LineageOS right from there, i just don't know all of the steps i have to do, and i want to avoid f*** up anything, anyone who can help me with a short guide?
Anyone?

If your RR is 6.0+ you can go directly to TWRP (Make sure you have an updated bumped-version too) and flash rom.
So, the right step are:
1. Download rom zip from lineage os website
2. Go to TWRP
3. Format system, data, cache and dalvik
4. Flash rom zip
5. Reboot
If you need play store and google apps you must flash this zip too https://opengapps.org/?api=7.1&variant=nano
If you need root you need to flash this zip too https://download.lineageos.org/extras (14.1 su ARM)
If you have a different version, going back to stock and starting from there is a better idea.:good:

Hello and thanks for answering! Unfortunately i have a 5.8 RR
So i take it that i better go back to stock and from there flash the latest version of Lineage, could you very quickly but effectively explain the steps to do that as well?

With 6.0 i mean Android Marshmellow or newer.
And about going back to stop you need to download the firmware and flash it with KDZ Updater.
There are a lot of tutorial online, and on xda too, well detailed with all necessary steps.

V30 is lollipop
For most of custom rom you need V30, so... Dont falsh previous firmware else you'll get black screen.
Check language and 16/32 storage too.

Thank you so much!
Great, i've done everything, and i'm pretty happy now, just have a few other things to ask i hope you're willing to answer.
First, is there a way i can improve reception, i feel sometimes my phone has some kind of problem because one second it catches the carrier, a second later it goes totally no service, it's very weird, maybe a different modem to flash could help that?
And the second thing is, is there a way besides xposed, to customize the navigation bar and few other things like the lock screen shortcuts?
