[Nexus 6P Q&A, Help & Troubleshooting] Exodusche:
I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.
[Nexus 6P Q&A, Help & Troubleshooting] msmcintosh:
Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".

I installed the factory Nougat ROM and still no service.

Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?

Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.
[Nexus 6P Q&A, Help & Troubleshooting] msmcintosh:
Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?

I don't have access to another carriers SIM card.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.
[Nexus 6P Q&A, Help & Troubleshooting] msmcintosh:
According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.

Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?
[Nexus 6P Q&A, Help & Troubleshooting] msmcintosh:
When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.

In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.
[Nexus 6P Q&A, Help & Troubleshooting] shubzk123:
I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.
[Nexus 6P Q&A, Help & Troubleshooting] Exodusche:
Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?
[Nexus 6P Q&A, Help & Troubleshooting] swamp2:
Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.
[Nexus 6P Q&A, Help & Troubleshooting] leanderson30:
could you detail how to do just that? Because I'm in Brazil and I have the same problem.

[Thinkpad Tablet General] ale_aas:
Hello there!

Because there is not much about this procedure for this version I leave a tutorial that has worked very well for me.

Warning:

Backup all your data first, because when unlocking the bootloader of the device, it will reset to factory defaults and delete/erase all!

This guide is for people who understand the risks of flashing and is totally under your responsibility!

Before doing anything at all, read this post carefuly!

Requirements:

- Lenovo Yoga Tab 3 10.1 YT3-X50F (I don't know if this method runs on other versions)

- SO: Android 6.0.1

- ADB Fastboot

- TWRP Recovery v3.0.2.7 for YT3-X50F

- Magisk v14.0 or SuperSU

Links:

15 seconds ADB Installer v1.4.3: https://xdaforums.com/showthread.php?t=2588979

TWRP v3.0.2.7: https://drive.google.com/file/d/0B6_OCYqbEKIac25wcjh6ZUFyZTA/view?usp=sharing

Magisk v14.0: http://tiny.cc/latestmagisk

Chainfires SuperSU: https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip

Steps:

1.- Enable "Developer Options" on your tablet :

Go to Settings / About this device / Tap 7 times on "Build Number"

2.- Go to Settings / Develper Options / enable "OEM Unlock" and "USB Debugging"

3.- Install on PC "ADB-Setup-1.4..3"

4.- Connect the Tablet to your PC via USB

5.- Extract twrp.img in TWRP folder in your PC and enter it

6.- Open a command prompt (CMD window) inside that folder (Shift + Right click)

7.- Check if all works: type "adb devices" (without quots). If OK the answer shows a serial number.

8.- Then type: "adb reboot bootloader"

9.- Check again with: "fastboot devices"

10.- Finally: "fastboot oem unlock-go" (it will reset the device and erase everything, including your internal storage)

9.- Copy Magisk or SuperSU in microSD or internal storage

10.- Check again: "adb devices"

11.- Fastboot mode: "adb reboot bootloader"

12.- Check again: "fastboot devices"

13.- Flash custom recovery: "fastboot flash recovery twrp.img"

14.- Press and hold "Volume Up" button on tablet

15.- Reboot into Recovery mode, type: "fastboot reboot"

16.- Press "Enter" (The device reboot into TWRP Recovery)

17.- Release the "Volume Up" button when TWRP appears

18.- Slide to right and change the language (see the picture)

19.- Make a NANDroid/Backup of your system files in case something goes wrong with Magisk/SuperSU.

20.- Go to "Install" and select Magisk.zip or SuperSU.zip from internal sotrage/microSD

21.- Reboot

22.- Done!

[Thinkpad Tablet General] fede01_8:
Thanks!

BTW, Have you find any roms for this model?
[Thinkpad Tablet General] jschwalbe:
Great work! Thanks.

Only part I got stuck on was step 9. If you're on a mac and it won't mount as a drive, do this:

adb push Magisk-v14.0.zip /sdcard/ (OR: just download it from Chrome on the Tablet.)

Also for step 17: I think Volume Up is to the RIGHT if you're looking from top on. (but still not sure, honestly!)

I'm working on a stock based rom for the x50f if anyone still has any interest
[Thinkpad Tablet General] dorpmuller:
Very interested if it's >nougat. I really hate marshmallow. Do you have more details?

The tablet is hideously slow no matter what I do. Only way I get any performance is I stripped out everything Google and use alternative apps.

Can't wait to see what you come up with!

Rich
[Thinkpad Tablet General] wjstone:
Unfortunately it is based on Marshmallow. For now the main things i'm working on is removing bloat, customizing things a bit and increasing speed. I'm happy to get any requests though I can't promise any particular results.
[Thinkpad Tablet General] Bloom_Kiitty:
Oh I'm very very interested!

Is your ROM based on stock Android or another ROM? If you're going to keep it at MM, what are your intended changes, exactly? Would it be possible for you to upgrade to the latest Android security patches and/or latest Linux stable Kernel? Also please strip away anything that wants/needs to connect to Google's servers, or, better still, anything that connects in the background to any kind of servers without user's permission. Nevertheless thank you ^^

Also a sidenote, I don't know if it's my fault somehow or a know issue, but the menus for WiFi/Bluetooth (not the settings in the statusbar) never show up any found enteries, so you might want to keep an eye out for that.
[Thinkpad Tablet General] Nube2Roots:
VERY INTERESTED! I really despise the Chinese ROM as it has no WI-FI, so no access to Inet. Really started a project just to debloat my tablet

HOW TO INSTALL 6.0.1 ROM w/ WiFi & GAPPS

for those who've been looking for a ROM with GAPPS i've found files and a method to install.

REQUIREMENTS:

UNLOCKED/UNLOCKABLE BOOTLOADER & ENABLED USB DEBUGGING ON TABLET FROM DEV OPTIONS!!!

lenovo ROW ROM: https://androidfilehost.com/?fid=11410963190603888989 (from xda user deadman96385)

packsparseimg.exe from this post: https://xdaforums.com/android/software-hacking/easy-unpack-systemxx-img-firmware-t3583543

adb/fastboot on computer

METHOD:

1. unzip ROM into adb directory (no subfolders)

2. put packsparseimg.exe into adb folder

3. (from: https://forum.hovatek.com/thread-24545.html)

open command prompt window in adb folder and run the following commands (wait for each one to finish before starting the next one):

packsparseimg -t system

packsparseimg -t cache

packsparseimg -t userdata

rename the generated .raw files as .img files. they're ready for flashing now

4. if you haven't already unlocked your bootloader and enabled usb debugging THEN DO IT NOW.

5. turn on tablet and connect to computer as normal - no special qpst connection method needed

6. on computer, go into folder with all the extracted files and find 8909_fastboot_all_images.bat

if all goes well then ROM should be installed successfully

i tried QPST/QFIL methods for HOURS and either firehose or sahara would fail... and i was tearing my hair out until i found this workaround method

hope you enjoy :)
[Thinkpad Tablet General] Iv0:
thank you, worked like a charm! :)
[Thinkpad Tablet General] pj.6206:
Hi,

Thanks for the instruction.

Unfortunately the ROW Rom is not available for download anymore.

I tried to find the user deadman96385 but couldn't find him.

Do you still have the file or know where I can get a hold of it?

thanks a bunch
[Thinkpad Tablet General] mistersmee:
Yep, I'm interested too. Anything to get this tab above Marshmellow.

By the way, will the roms for the Lenovo Yoga Tab 3 Plus (YT3-X703F/L) work for this? Just a stupid thought I had, as that Lineage 17.1 and a bunch of other roms.
[Thinkpad Tablet General] :
Sorry to dissapoint you but no, they are completely different devices with similar input output hardware. The Pro is an Intel based SoC with a Quad-Core x86_64 architecture, while the plus, if I remember correctly, is a Qualcomm Snapdragon Octa-Core with arm64 architecture... and that is only the main difference.

Also, [MENTION=4160775]wjstone[/MENTION] is talking about a Stock ROM which is what I call a modded firmware. A tweaked kernel, a modified system based on a previously existing firmware, so, it's not really any newer than Android Marshmallow...
[Thinkpad Tablet General] mistersmee:
Yeah, thought so, they are different devices, so it wouldn't work.

It's ok, I had wished to get this above Marshmellow, but can't have everything, unless I myself make it happen, which isn't possible now with my level of (in)experience with building a custom ROM. Maybe in a few years.
[Thinkpad Tablet General] :
No, I don't know. I thought I was in a YT3-X90F thread. Please ignore my previous comment.

Thanks. I downloaded it and followed the instruction. It didn't work exactly the way you mentioned.

The zip file contains 3 folders. I had to copy the content of "Maincode" folder in the adb folder and then execute the codes.

I had problems after running "8909_fastboot_all_images.bat" file. It only restarted the devices. So some time after several tries I restarted the devices by holding the buttons and it finally did the magic.

Later OTA updater notified that there was a new update to "YT3-X50F_S000123_181225_ROW" which obviously I couldn't install because of TWRP.

Learning from experience I googled it and luckily found it on "lolinet" (Since I'm a new member I can't post links). Following your instructions everything went smoothly.

Hope others find this useful.
[Thinkpad Tablet General] pj.6206:

Hey I'm interested

Can anyone help me !

I had also made a stock based ROM for this. It installs through TWRP without any errors but stucks at Lenovo boot logo.

What I have and I have done :

- Lenovo Yoga Tab 3 10" X50L

- Unlocked bootloader and installed TWRP

- Made a stock based ROM for this device and flashed (No errors so far :D)

- But problem starts from here !

- I rebooted to system but it stucks at Lenovo boot logo never starts

- Though I could boot to bootloader or TWRP successfully to restore the backup

Any help will be appreciated

Thanks in advance :)
[Thinkpad Tablet General] Jobin791:
This is my first time trying to root or anything and I'm stuck right at the end. As far as I can tell I successfully got TWRP on the tablet and everything but after running 8909_fastboot_all_images.bat my tablet is now stuck loading into recovery mode. When it ran multiple times I got "target reported max download size of 262144000 bytes Invalid sparse file format at header magi". Maybe I didn't install ADB properly? Also related, how would I now get into TWRP to access the backup I made? Hopefully this isn't too complex and someone can help out, I haven't done any real programming or computer work in 6 years so this was a struggle haha.
[Thinkpad Tablet General] diagonals:
did packsparseimg work correctly on the rom files before you attempted to flash them? that would be my best guess.

as for twrp, your backups should be in a folder either on the sd card or internal storage of your tablet. good luck!

[Thinkpad Tablet General] fede01_8:
Yes, Lenovo's R software. It had the same problem it has now: when you first boot the tab, the Lenovo logo appears and then it boots again infinitely. This happened after an OTA update (which I thought was odd for such an old tablet). It was working fine before.
[Thinkpad Tablet General] blue4scorpio1:
So to understand the lenovo Rescue does not work for you? Youve forced the tablet to shut down and put it on the pc with leneovo rescue ,you did the rescue and did not work?
