[guide] repairing lost imei in lenovo yoga tab 2 1050l and others android 5.0.1 - Lenovo Yoga Tab 2 Guides, News, & Discussion

After long fight I managed to repair lost IMEI after changing roms and accidentally formatting ESP partition.
Prerequisites:
1. ROOT
2. Intel Phone Tool 191
3. Windows with ADB installed and android USB drivers
To make things short:
1. need root on tablet
2. turn on ADB debugging
3. connect tablet to Windows PC (I used Windows 10)
4. run "cmd"
5. type "adb shell"
6. type "su" (root is obligatory)
7. type "setprop system.at-proxy.mode 1" -> source http://lenovo-forums.ru/topic/22471...-planshetah-yoga-2bez-nalichiya-bekapov-i-tp/
7a - this actually makes your device discoverable by Windows as Virtual Com port and this is needed for Intel Phone Tool 191 to connect
7b - you need to set Virtual Com Port as COM1
8. Once connected in Intel Phone Tool go to Modes -> Security
9. Change IMEI in all places necessary
10. Reboot and BE HAPPY AGAIN!
Hope this helps somebody and he won't loose so many time on this problem as I did.

[Q] ABD Drivers + Windows 7 issues (plus a couple more questions)

Hello XDA Community.
I'm attempting to install the new RC of CyanogenMod-6 for the Hero CDMA. I'm currently running the stock 2.1 version of Android. I've been following the guides that were referred to in the thread (I tried posting the urls but new users can't do so to prevent spam).
I've successfully rooted my phone and now I'm trying to do a Nandroid backup. I'm running Windows 7 32-bit and have hit a road block with ADB not recognizing my device. I followed the guide put together by Nephron to install the Android SDK. I've spent several hours going through threads and doing google searches looking for the solution. I have debugging turned on and I don't mount my SD drive when I plug the USB cord in. I've used USBDeview as some have suggested to delete current HTC drivers and then reinstall - no luck.
Here is a screen shot of what happens when I plug in my Hero:
See attached - "failedinstall.jpg"
Then I'll go to device manager to manually install the driver (it never allows me to manually select upon connection for some reason):
See attached "devicemgr.png"
And then this is the message I get when I point it to the "right" folder with the drivers:
See attached - "unabletoinstall.png"
So, on the Android SDK site I noticed this message:
"The USB driver for Windows provides support for the following Android-powered devices:
T-Mobile G1* / ADP1
T-Mobile myTouch 3G* / Google Ion
Verizon Droid*
Nexus One
* Or similar hardware on other carriers
Any additional devices will require Windows drivers provided by the hardware manufacturer.
^So is all of this HTC's fault? I've downloaded a couple of different .zip folders from different threads claiming that these drivers would work. But none of them have yet to do the trick for me.
I'm new at this so I have a few other questions as well:
Most guides I've read about how to do a Nandroid backup always recommend flashing a ROM b/f doing a backup. But I want to backup my current stock rom and settings before I flash. Wouldn't I want to create a recovery image before installing any other ROMs? Perhaps I'm misunderstanding some requirements?
Referring again to the thread on the CyanogenMod RC, can someone help me understand step #3? How do I know if it is necessary to update my radio? What implications does this have? I tried looking for info about this on the wiki and I couldn't find anything comprehensive enough to answer my question.
I'd appreciate any guidance!
Before you modify anything you will want to boot into recovery, assuming you flashed one, by holding down Home and turning the phone phone back on(power button). But since you don't have adb working then you probably haven't. You can still do this using terminal on your phone.
Download terminal emulator from market and then download a revoery image (AmonRa 1.6.2 or Darch's 1.7xx) and then mount your sdcard to the computer and transfer the recovery to the root of the sdcard. Open up terminal emulator and type in
Code:
su
cd /sdcard
flash_image recovery recovery-RA-heroc-v1.6.2.img(type the exact file name of the recovery you are using)
reboot recovery
If you had factory 2.1 on your phone then you have the latest radio. The radio can be flashed just like any ROM, but make sure that the radio is not for GSM phones as this will destroy your phone.
Instructions from Android Developers and ADB, Fastboot, and Nandroid for Noob
Download the latest Android SDK.
Unzip to C:\AndroidSDK
Right-click on (My) Computer, and select Properties
Go to Advanced settings
XP: Click the Advanced tab
Vista/7: Click Advanced system settings on the left
Click the Environment Variables button
double-click on Path (under System Variables)
Add the full path to the tools/ directory:
C:\AndroidSDK\tools\
(make sure a semicolon ( separates this new path from all the others)
Latest windows sdk version appears to need: "C:\AndroidSDK\android-sdk-windows\tools", install location may change with further updates..
Run C:\AndroidSDK\SDK Setup.exe
If you get an error about not having Java SDK installed but you do, add the path to 'bin' within your Java installation location to the Path environmental variable as described above before the sdk entry you just made. (eg add "C:\Program Files\Java\jdk1.6.0_20\bin;") This is likely to only be necessary where the 64 bit Java SDK is installed (obviously) on a 64 bit machine.
If it gives you an error about http go to settings and click on "Force http//....."
Unselect all options except for the USB driver
If you can't get the setup to work, download the USB-DRIVERS folder - HERE (Windows XP/Vista/Windows 7)
On your phone, click Settings > Applications > Development and make sure USB Debugging is on.
Plug your phone into your computer via USB cable (it needs to be on). It should say installing drivers if using Windows.
After it installs the drivers, goto the Start menu and type cmd into the search bar (Vista or higher) or click Run then type in cmd (XP) to open the command prompt.
Type the following into the command prompt window:
adb devices
You should see a serial number pop up, it’s the serial number of your phone. This means you are all set. If you do NOT see a serial number, then we need to reinstall the drivers.
Download USBDeview
While the phone is still plugged in, open USBDeview and sort by manufacturer. Find all the HTC/Android drivers and uninstall them all. (Windows Vista requires program to be run as an administrator, otherwise files won't uninstall.)
Once all have been uninstalled, unplug the phone from the USB cable and plug it back in.
The correct drivers should reinstall automatically (check the drivers as they are installing, one should say ADB Device driver).
To check, go to Devices in your Start menu then click on the “Android Phone”. Click on the Hardware tab, and check the list of drivers for ADB Interface under Type.
Done! Now you can use ADB to alter your phone from your computer.
If all else fails try installing HTC Sync software-- http://member.america.htc.com/download/Driver/HTC Hero (Sprint)/HTC_Sync_2.0.40.exe and then removing the drivers for it and then trying to install the android sdk drivers
Or you can dual boot with Linux and all you will need to do is download and unzip android sdk and edit 2 files and everything will work.
WOW>>>>>no that is way to confusing. the best thing to do is install vmware workstation. Then do a virtual WINDOWS XP MODE. from there you will be able to install the drivers and such in order to get the phone to be seen.
the version of htc sync i used for all my computers including win 7 was 2.0.33
if you want it then just pm me and I will get it to you
they don't offer it for a download anymore
this version corrected all my driver issues

IMEI ****

hi i have cm 7.1 and restore it to stock
only my phone say wrong IMEI numer i try
1. Connect phone by USB
2. Enter 1809#*990# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number
8. Reset
step 1 2 3 is good and de rest i dont understand what i must do , cam some one help me ?
Hyper terminal is a tool normally pre-installed in windowsXP windows2000 etc allowing you to communicate raw data to a device via a COM port. (In the old days it could be used to connect to dialup modems etc which were plugged in via RS232 ports). I dont think it comes pre installed on windows 7 by default so you may need to manually install it.
In Win XP it can normally be found Start Menu -> All Programs -> Communications -> Hyper terminal or found here C:\Program Files\Windows NT\hypertrm.exe*
*Assuming you installed this windows component when windows was installed.
Hope this helps - good luck
Seem like one who doesn't know about Seagate Barracuda problems
Simply that's the last time i used one... just google the problem, and where the solution is should also be hyperterminal zips around there to for newer OS.
PUTTY should also work...

[Q] One not detected properly in fastboot mode

Hi there,
I`ve got the following Problem:
My One is not detected properly in fastboot mode, adb works like a charm (all cmds working)
In fastboot mode windows says that the device cannot be started (code 10) and cmd cannot find the device and it`s also not charging in fastboot...
I`m using Windows 8 and I know that there are problems with driver signatures, so I disabled the checks through advanced boot, uninstalled all drivers and reinstalled them (the strange thing is, it worked like a charm with my HOX)
After that still the same issues... Then I uninnstalled the HTC drivers and tried the drivers from Google SDK and after that the drivers from PDAnet but nothing helped...
Then I read that there are Problems with USB3.0 and fastboot but I only got USB3.0. So I tried different USB ports and reconnected many times (about 30 times) and maybe the phone says "fastboot USB" but in cmd it`s still not detected...
As I said before with my HOX it worked like a charm... (also Win8 and USB3.0)
Any ideas?
Thanks for your help!
togx
Try disabling Fastboot in the Power Settings.
I tried it again with fastboot disabled but it still doesn`t work... :/
same problem here....

hey envoy_467,
I found a solution for this issue:
It seems that microsoft´s own driver for the Intel USB3.0-Host breaks the support for several devices. You can install the Intel drivers for Win7 on Win8 (search google: Windows 8 and Intel USB3.0 host controller there should be a link to plugable. I´m not able to post links cause I don´t have enough posts...) but it only works with the Intel host.
Hope it will help you too!
greetz,

usb device not recognized
I'm having a similar problem using windows 8, but I tried both my usb 2.0 and 3.0 ports but results in same problem. I have a t-mobile HTC One S (JB 4.1.1). Everytime I try to do the fastboot to get my token id my pc tells me my usb device is not recognized. Does anyone have any suggestions? Thanks in advance!
Try THIS
Sorry to bump this thread, but it's better than creating a new one.
Anyway, I have the same issue as the others here: fastboot won't work at all.
Btw, I've tried all possible solutions but installing the intel driver isn't possible due to a limitation on Windows + Intel 8 Series.
Windows 8, Intel 4th generation processor (8 Series/220) on a Gigabyte GA-Z87N-WIFI.
USB eXtensible Host Controller driver by Microsoft can't be modified to work with the Intel 8 Series driver. When trying to install it it says that my PC doesn't have the requirements to install the program (driver can be found here -- 8 Series ONLY!!) probably because I'm on Windows 8 (no, setting the app to run with Win7 compatibility mode doesn't work either).
Using Naked Driver 0.72..
Has anyone tried with a virtual machine? Maybe I could install Ubuntu on a VM to test it when I get the time.
Any other ideas?
VM doesn't work.. Since Windows won't recognize the phone while on fastboot that means that the VM Linux won't find the devide either.
LiveUSB won't install the android SDK either.. I'm stuck..
FIXED, kinda.. Workaround on Linux.
More info:
Just did it..
But not on Windows..
I've created a LiveUSB from Ubuntu 12.04 using the "Universal USB Installer" from: http://www.pendrivelinux.com/downloads/
When creating the LiveUSB I've created with 4gb (4096mb) of free space on a 16gb flash drive just in case, but you can make it work with a 4gb flash drive.
Then I installed the Android SDK.
Then I was able to use fastboot to change the CID to 11111111.. Working great.. Now let's download the developer ruu..
Tutorial used to install the SDK: http://askubuntu.com/questions/318246/complete-installation-guide-for-android-sdk-on-ubuntu
To run all commands faster, just type "sudo su" before starting. After that type "apt-get -f install" to clean everything.
Remember: To install anything the tutorial asks you have to use the command "apt-get install name-of-package", where the name is the item the tutorial says.
Go up to Step 4.
Download and Unzip/extract the AndroidSDK to the desktop (just the SDK, you don't need the full bundle).
Go to the unzipped folder, go to the Tools folder, double click "android", run in terminal, install the SDK and the TOOLS.
When finished, open a terminal window, navigate to your unzipped folder, than navigate to platform-tools and use the command "./adb" and "./fastboot" to work your magic..
Edit: Still not able to install the RUU..
At least now I have the phone ready.. Just have to find a new PC to install the RUU..

Recovery mode bricked on USB Notice picture after try to enable root

Hi
(Sorry for my little english, feel free to speak french if you can)
I have try to root my 4X HD for using a better recovery app (recover pictures deleted in sd card, now you know my skill). I have use this page: (as newbie i cant post outside links)
n fact, I never had an Android device where this was that easy to achive! Our friends at XDA-Developers offer a guide and the necessary tools in this thread. Having a "Microsoft free zone" and "only" running Linux machines (yeah, even the Android ones run a Linux kernel), I was able to follow up those steps with a little adaption here and there -- and so I will sum up the results for Windows and Linux users as well:
Preparation
First you need to download the required tools, all of them available at the linked XDA-Developers thread:
o4xr.zip is the rooting toolkit
IS11LG_SystemBackupTest.signed.apk to prepare your device
Windows users only: LGUnitedMobileDriver_Ver_3.7.2_LG-P880_LGO4XHD.zip -- the Windows drivers for the device
Having everything downloaded, some additional steps are necessary at your computer:
Windows users only: Unzip and install the drivers
Linux users: Make sure adb is able to detect the device (check with adb devices). If it's not, see at the end of this answer for some hints.
Everybody: Copy IS11LG_SystemBackupTest.signed.apk to your Optimus (e.g. after connecting it via USB in MTP mode, copy the file to the internal SDCard)
Everybody: Create a new directory, unzip o4xr.zip there, and change into this directory.
The rooting process
On your Optimus, go to Settings→Security and make sure "Unknown Sources" is TICKED (i.e. contains a checkmark)
Go to Settings→Developer Options and enable "USB Debugging"
Now install IS11LG_SystemBackupTest.signed.apk (e.g. use a file explorer to find and "launch" it)
Open the "SystemBackupTest" app you just installed. Nothing spectacular will happen, so don't be disappointed here.
Hold the power button and choose "Power off and restart".
When you can see the lock screen, you may notice that the phone is running very slowly, this is normal.
Once the device is fully started up again, connect it to your computer with an USB cable. Make sure the phone is in "Charging Only" mode.
On your PC, open a terminal (Linux) resp. command (cmd.exe, Windows) window and change into the directory you've extractedo4xr.zip` into.
(on Windows, you may need admin privileges: right click, run as administrator. On Linux it did fine for me without superuser/root permissions)
Now run the rooting script:
Windows users: type root followed by the enter key
Linux users: type ./root-linux.sh, also followed by the enter key
Any Mac users? Type ./root-mac.sh, also followed by the enter key. Don't worry, it won't root your Mac/Linux machine (Windows users: it is unlikely to root your box, either
DO NOT DISCONNECT YOUR PHONE WHILE THE SCRIPT RUNS! Wait while it does its job. During that process, the phone will reboot automatically a couple of times. The script will inform you about this in your command/terminal window. Once the command/shell prompt returns, the misdeed is accomplished
Now uninstall SystemBackupTest from your Optimus. Do not launch it again at this state, or you might have to start over from step 5
On your phone, open up Google Play Store and search for "SuperSU". Update the app when prompted, then open it. Press OK to update the SU binary.
You now have root and can safely restore the "Unknown Sources" and "USB debugging" settings back to how you had them! Congratulations! Next steps are to install Titanium Backup, LBE Privacy Guard, and all the other things you might need and which require root!
At step 8. i got "command not found" in Terminal (Linux Mint), assuming script don't work i have reboot my device.
Since my phone boot but is very very slow and screen is friezed, even if i can unlock my SIM card by memory pattern (without sim card and always by memory i can see Settings of android but not down the list).
In recovery boot (Sound up + Power), my device show me a picture that would say "dont unplug charge and usb".
I guess my phone is not rooted, adb can list it but not fastbood. LG software (on windows 7) cant communicate with it because usb driver not work. I guess i've try and read more since 8 hours but my brain is off right now. Any help will be very welcome.
Cheers

Easier way
1: Download android studio. 2: Open terminal and type in cd /Users/<User>/Library/Android/sdk/platform-tools. 3: Put ur device into fastboot and unlock bl and so on.
Android studio: https://developer.android.com/studio/index.html
And drivers are not required because mac is linux based like ur android device.

using hombrew
install it:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
install tools
brew install android-platform-tools
everything is the same as in windows or linux. looks pointless.
When I try to run "./adb devices" I get "-bash: ./abd: No such file or directory"
ive rooted phones in the past, but never had to do much with terminal commands or adb... not really sure what im going wrong here... assuming adb not installing correctly?
well, after several more hours of reading ive finally figured it out... im not sure how ive never had to do this on one of my phones in the past
and what did you figure out...?

Exactly this. The OP is a bunch of unnecessary steps.
Does this work for OP3T too?
