[RECOVERY][TB-X605F/L][OFFICIAL] TWRP 3.6.x for Lenovo Smart Tab M10

[Yahoo Mike]

This version of TWRP works on both the TB-X605F (wifi) and TB-X605L (LTE). It does not work for the TB-X605FC/FL (Tab M10 FHD Rel).

Warning: this TWRP is for the Lenovo Smart Tab M10 with the Snapdragon 450 (SDA450) chipset. This image will not work for the second gen M10 (TB-X606F/L), which use a Mediatek SOC. See this thread.

For the M10 HD (TB-X505F/L), see this thread. For the TB-X505X, see this thread.

Possible issues with TB-X605L
If the latest version of TWRP for TB-X605F doesn't work for your TB-X605L model, try version 3.4.0-0 from twrp.me.

Installation
TWRP for this device is officially supported. You can download it from twrp.me or in the TWRP App (from the PlayStore). Installation instructions are included on twrp.me.

It is recommended that you also install Magisk. This will ensure TWRP remains your default recovery.

Step-by-step guide

1. download TWRP to your PC (see the Download section below)
2. download magisk.zip to your MicroSD or OTG device. Get the latest Magisk zip file here.
3. if your bootloader is already unlocked, go to step 4. To unlock bootloader:
   • on tablet: go to Settings->System->About and press "Build number" 7 times to enable Developer Options.
   • on tablet: go to Settings->System->DeveloperOptions. Turn on: "OEM unlocking" and "USB debugging".
   • connect tablet to your computer. Tablet will ask for permission to "Allow USB debugging". Tick "always allow" and select "OK".
   • backup any files you want to keep to an external device (MicroSD/OTG/computer), because the next step will wipe all your photos, files, google account etc on the tablet.
   • Now unlock the bootloader:
     

     adb reboot bootloader
     fastboot oem unlock-go
     fastboot reboot

4. flash the twrp image:
   

   adb reboot bootloader
   fastboot flash recovery twrp.img

5. if you haven't loaded Magisk yet, go to step 6. If you have already loaded Magisk, you can just reboot and you're finished:
   

   fastboot reboot
   adb reboot recovery

6. load Magisk (step one): reboot to recovery. Do not reboot into the system, because it will over-write TWRP with stock recovery. If that happens, go back to step 4 and start again. When you issue the reboot command (below), you have to immediately press the button combination to reboot to recovery (TWRP). Here are the steps:
   • issue the reboot command:
     

     fastboot reboot

   • immediately press and hold all three buttons (Pwr+VolUp+VolDown). The tablet might reboot twice. Release all the buttons when you see the TWRP screen, or hear your PC acknowledge that ADB is connected.
7. load Magisk (step two): flash Magisk. In TWRP:
   • select "Install"
   • use "select storage" to locate device you stored magisk.zip on.
   • press the OK button
   • select the Magisk zip file
   • swipe to confirm Flash
   • when Magisk is finished, hit the back button to go back to main TWRP screen.
   • select "Reboot" then "System"
8. if the Magisk Manager app wasn't automatically loaded, you can get it here.
9. finished!

If you prefer to use button combos, rather than fastboot/ADB commands:

• Vol Down + Power = fastboot mode
• Vol Up + Vol Down + Power = recovery mode

Encryption/Decryption

When you load the stock ROM, it creates and automatically encrypts the data partition. If you are not using the correct TWRP version, the data partition might be empty (0 MB). This is because TWRP failed to decrypt the data partition.

If your data partition is 0MB in TWRP, make sure you have loaded the latest version of TWRP (Nov 2020 or newer). Older builds required the security patch levels to match on TWRP and your system.

If you want to remove encryption completely, then you can use the dm-verity-forceencrypt tool. @turboperson123 has put together some instructions to remove encryption. If you've already loaded TWRP, then you only need to follow steps 6 and 7 from that post. @turboperson123 's method uses @Zackptg5 's Universal DM-Verity, ForceEncrypt, Disk Quota Disablers tool to remove encryption and dm-verity.

FAQs

Can I use this TWRP on other M10 and P10 tablets?

There are quite a few variants of these Tabs that use the Snapdragon 450 (SDM450) chipset:

• TB-X605F (Tab M10 wifi) - tested working this TWRP
• TB-X605L (Tab M10 LTE) - tested working with TWRP ( thanks @alexupsa )
• TB-X705F/L (Tab P10) - no. Use the twrp available on this thread.

For the TB-X505F/L (M10 HD) see this post.

NOTE: the TB-606F/L (M10 2nd gen), TB-X605FC (M10 FHD) use different chipsets, so this TWRP won't work.

Why is my "Data" partition 0MB?
See the second post in this thread.

What should I backup?

Short answer: everything.

But the bare minimum might include:

• System Image
• Vendor Image
• Firmware/Modem
• Persist
• Data
• Cache
• Boot

How do I root my device?

To root your device, here are the instructions for the:

• X705F (thanks to @Chaser42)
• X605F/L - follow steps 6 & 7 in the OP above. If you don't want to load TWRP, then try something like @Long_Sam's patched boot.img method.
• X505F/L - follow the "step by step guide" in the OP above. Just make sure you use twrp for X505F (not for X605F).

How do I load OTAs with TWRP?

Note: if you ran the dm-verity-forceencrypt tool to unencrypt your /data, then the steps below will not work.

1. select "uninstall" in the Magisk Manager app. If MM doesn't reboot the system, then reboot - this will re-install stock recovery.
2. install the OTA (either in the system or using stock recovery).
3. re-flash TWRP (for the new security patch level)
4. re-install Magisk

Lenovo has released quite a few variants of the Tab M10 now. I'm not sure this TWRP will work on all of them.

There are now even variants of a variant !

[B]M10[/B]       with SDM-450    models:  X605F  (wifi) & X605L (LTE)
[B]M10 HD[/B]    with SDM-429    models:  X505F  (wifi),  X505L (LTE) & X505X (LTE Bands 1,2,3,4,5,7,8,20,38,40)
[B]M10 FHD[/B]   with SDM-450    models:  X605FC (wifi) & X605LC (LTE)

The M10 I have is shipped with a Snapdragon 450 (SDM-450) chipset & Hardware Code 63. But I see on their US site that Lenovo are now putting the SDM-429 in the X605. This might cause a problem with TWRP. I'm not sure if the kernels will be compatible.

The TWRP I've posted is for the X605F/L SDM450 (HW=63). I might need to compile a different TWRP for the SDM429 versions of the X605 & the X505.

If your X605 or X505 shipped with the SDM429, can you let me know if this TWRP works ? I need to know the Hardware Version, CPU and Hardware Code. Hardware Version and CPU are in System->About. The Hardware Code is in brackets after the S/N on the sticker on the back of the tablet, eg S/N Hxxxxxxx (63).

If you have an X605FC/LC, let me know if this TWRP works. I think it will, but I want make sure.

I have one with the 429 TB-X505F SD429 HW71 If i get some time today I might be bale to try it. I'll post soon as I do.

This morning I successfully compiled and ran the P10 kernel source on my M10. I had to tweak the config a bit. I tested it in TWRP. No problems.

Tomorrow, I'll inject it into the boot.img of the system ROM and see what happens. If it is mostly stable, then we're on the way to LOS for the M10. If it's completely stable, I'll push the source up to github.

I'll continue to use the stock kernel for the released versions of TWRP in this thread, though.

Thanks to @clsA for helping me work out that the M10 kernel is a subset of the P10 kernel.

@Yahoo Mike
thx for the twrp

succesfully flashed on my X605L

"Stock recovery image (recovery_stockROM.img) from TB-X605F_USR_S200065_1905280020_Q00332_ROW - just in case something goes wrong & you need to restore stock recovery. Only use this image on a TB-X605F. If you need it for any other variant, just ask in this thread and we'll track it down for you."

do you have the stock recovery for the X605L ?

how can i backup "DATA" inside twrp ?

will this help ?

[Yahoo Mike]

...
do you have the stock recovery for the X605L ?

Now I think of it, you don't need it. If TWRP fails to flash, then stock recovery will still be there. If stock recovery is still not loading, just boot into the system and shutdown. When you shutdown, the system will re-flash stock recovery for you.

...

Have a look at the second post.

TL;DR...the dm-verity-forceencrypt tool will do it. But it will break the next OTA. The unencrypted P10 guys are having problems at the moment with this.

I've tried to get TWRP to unencrypt the data partition, but I can't get KeyMaster to initialise successfully. Maybe the next version of TWRP will be able to do it.

 

[11mackey11]

Yooo. Sorry I took so long works been crazy. I cant get it to reboot into twrp recovery. Its flashes the 605 recovery then I follow the next steps in the guide but I can only get it to reboot to the stock recovery screen. Run the reboot recovery command then immediately hold the volume + - down along with power. I tried a lot I let reboot twice then let off, and nothing then I tried several more times. Reflashing then the next step. I must not be holding my mouth...err I mean pushing the buttons right or the recovery just isn't gonna work. Add I'm very newbie at rooting and customizing. I've I've rooted one phone. A 70$ moto g5 plus I got off Ebay that was basically brand new. Installed twrp recovery and magisk. I bought that cause I have SD note 9 I cant root and have this need to play YouTube videos in my truck lol. Let me know if you have any suggestions I can try. Or ideas that might make it work. I pretty much fubard the tab and (at a different time) before I tried this recovery and was able to reflash stock img though odin.

Don't be too hard on yourself...you've done well to get this far.

I just had a quick look at the kernel for the X505F. It's very different from the X605F. So this TWRP definitely won't work for you. Sorry.

If you want me to build a TWRP for the X505F, PM me and we'll work something out.

How do you remove twrp I think that or magisk is giving me the booting issues. Half the time I reboot for things it gets stuck. Not sure if it's root or twrp but I can't seem to remove either.

If you uninstall Magisk, then the system will overwrite TWRP with stock recovery the next time you reboot. Just tap "uninstall" in the Magisk Manager app. You can also remove Magisk from TWRP following these instructions.

What kind of boot issues are you having? Are you using a TB-X605F with SDA450? Or is it something similar?

 

[cbomb1337]

I am using Tb 605f it seems to be booting fine now after removing this riru module and edxposed. I'll just leave that and stick with just viper 4 Android lol
Do you know if them modules for increasing speed work? I think one of them was called fde and there the doze one.

Good to hear it's all working again.

Sorry, I haven't tried any of those tweaks.

Lenovo have updated the stock ROM they serve for the TB-X605F through LMSA rescue. It's now at TB-X605F_USR_S210126_1910290024_Q00332_ROW. This is the latest update. There are no OTAs to apply. The M10 is due for a security OTA pretty soon, though. The P10 has already received it.

Unfortunately, it's no longer possible to post a direct link to Lenovo's website for this ROM. You'll have to use LMSA to get it.

FYI. Lenovo have changed how they serve the stock ROM. The ROM is now kept at rsdsecure-cloud.motorola.com. LMSA seems to generate (or request and receive) a one-off time-limited credentialed ticket for the download. You can't download the zip files without the credentials attached to the URL.

If you really want to, you can still intercept the URL in download_resources.json in the LMSA download folder.

 

[cbomb1337]

is there anything new in the update. i might hold of because i dont want to lose root.

 

[Yahoo Mike]

is there anything new in the update. i might hold of because i dont want to lose root.

No, there's nothing new. This isn't really an update, it just seems to be a consolidation of the old stock ROM and incremental OTAs.

 

[Yahoo Mike]

This is only for M10 wifi (TB-X605F) with SDA450.

The latest OTA for TB-X605F has just landed. It's available on your tablet, or directly from: TB-X605F_USR_S210126_191029_Q00332_ROW_TO_TB-X605F_USR_S210152_200120_Q00332_ROW_WCE26E2CD5.zip.

The update takes the M10 to:

build:          TB-X605F_USR_S210152_200120_ROW
security patch: 1 January 2020
kernel:         3.18.120-perf-gd60e12b6-dirty

If you have TWRP and root, you'll need to:

1. select "uninstall" in the Magisk Manager app
2. install the OTA (from SD card) in recovery and reboot
3. re-flash TWRP
4. re-install Magisk

only if you unencrypted the data partition
If you have unencrypted your data partition, it will be re-encrypted during this process. Make sure you back it up before you start the OTA. You might also need to restore the TWRP backup you made of the vendor partition, before the OTA will run. Once the OTA, TWRP and Magisk are installed, you can re-run the dm-verity tool.
