I have the same problem :/

SOLVED
AFTER ROOT, NEVER EVER UPDATE YOUR SOFTWARE IF THERE IS ONE
Search for " Lenovo A3300 Development XDA " by vjtigas and find and download your stock firmware there.
After that unzip the file and install the preloaded driver on you pc.
And then open the SP flash tool (in the file) and load the scatter file. Press download. Force turn off your device and hold power button and volume up/down or all of them together and connect the device to your pc.
Your PC will detect your tab and the SP flash tool will install the firmware. (Don't unplug your tab while installing). After finish unplug it and turn it on. First boot may take a long time.
Thanks me if I helped.

Boot Loop after installing a custom ROM

Hello..!!
I need some help here. I tried to flash a custom ROM (X-Note (build 6.0) for Galaxy S5 GM900F) and then flash a new bootloader, the problem is that my device will never pass the booting process. I was stuck with the logo and black screen. I have searched and tried tons of tutorials and fixes but have not solved it.
I even tried to wipe Dalvik cache, wipe data, format system. I even put out the battery and leave it for sometimes, then on but the problem is still there.
This link to bootloader that I downloaded and flashed using Odin (after successfully installing custom ROM) and also the instructions that I followed to install the custom ROM.
https://www.androidfilehost.com/?fid=23622183712475277
When I try to re-install stock Samsung via Odin, it shows a Fail message. I don't know where to go from here and I'm really worry that my phone will never come to work.
Please help me to solve it.

I'm too busy today to describe this in detail.. but here are a few comments that may help you.
First, it is fixable. Usually it's enough to boot to recovery mode (phone off, then press and hold home + volume up + power buttons). Then from the recovery mode menu, choose wipe system cache. Then reboot. If you still have an issue then try a system data format from the Settings menu (this will erase user files!).
And as a last resort, restore a backup (if you have one) or a full, stock firmware image with Odin or Heimdall. Odin is infamous for being a bit picky, so don't panic if you get a failed message. That happens to all of us. Look for a detailed Odin tutorial or how to flash back to stock firmware thread that has Odin tips e.g. use a different USB cable + USB port. Temporarily turn off anti virus on your PC.. If the Odin write fails, do not close the Odin window. Just pull the battery and USB cable from your phone again.. put the battery back.. go back to download mode (home + volume down + power), plug the USB cable back, then press the start button in Odin again. It's important that the Odin window was open the whole time.
It may take a few tries (Odin can be frustrating) but you'll succeed.

Thanks for your words, you give me some hope because I thought my phone is now useless. I'll try again as you said.

[Q] [GT-S7710] Samsung Bootloop

Hello!
Today I started rooting my S7710 for linking Apps to external SD! Everything works fine, since I tried to convert the "Internet-App" (Systemapp) to an UserApp -> maybe you know the function of Link2SD.
After pressing the "Convert" button, the App tolds me to reboot my device - well, holding the power button -> select "reboot" -> bootloop with samsung logo.
Since then, I tried several ways to fix this problem:
1.) Re-flash rooted ROM - useless
2.) Re-flash OFFICIAL ROM of samMobile - useless
3.) Re-flash OFFICIAL ROM, afterwards CWM - useless
Two things to point 2:
When I tried to access the CWM-Recovery by holding VOLUP+HOME+POWER my device restarted 2-3 times (recognized by vibrations, display was black)
after those restarts, these images appeared:
andre-k.at/img/image1.jpeg
andre-k.at/img/image2jpeg
4.) Re-flash via Samsung KIES, ODIN-Mode -> "Firmware Actualization and Initialisation" .. also passed and the f**king Bootloop is still there ..
I am at my wit's end, so please help me please !
If you got the right answer for me, I'll sponsor a beer via paypal ;o)
Thanks,
EDIT: SOLVED AFTER FLASHING WITH KIES OFFICIAL -> RECOVERY MODE WORKS AGAIN -> FACTORY RESET / WIPE DATA -> BACK IN PHONE
Thanks so far!
Same Problem-Need some Help
Good evening Karnebi, I have the same problem you used to have with the samsung xcover2 model gt-s7710l. It's stuck in the samsung logo. According to your replies, It seemed I'm not using the official ODIN version, which I wonder If it's possible that you can provide the link for downloading Odin's official version and the ROM for my phone just to compare with the one I have. Greetings from Venezuela.

Yoga Tablet 2 - 1050F Lollipop Ota - Return to stock KK

I captured the lollipop update that came out today. I have a nandroid backup and I'm going for the update. We will see if the new tethered CWM works to get root back... Stay tuned.
Turns out rooted users will need to return the tablet to KitKat stock. I found this info in 2-3 places in various languages. Here is hopefully a clear step-by-step to get back to KK stock and then take the OTA.
This can BRICK your device, so use at your own risk. Files are supplied as a courtesy and not mine
1) Download - This - AFH - kitkat-YT2-1050F_S0198_150422_ROW.7z (This updated readme file here)
2) Extract the zipfile to a directory on PC somewhere
3) Goto "tools" folder and install the exe's in this order
a) PhoneFlashTool_4.4.4.1_external_win32.exe​b) iSocUSB-Driver-Setup-1.2.0.exe​c) IntelAndroidDrvSetup1.5.0.exe​4) Start PhoneFlashTool and select settings (Upper left corner)
5) Tick "force sparcing" and change size to 500mb
6) Power off tablet and connect with usb
7) From off, hold volume up and power until tablet vibrates and release power (still holding volume up)
8) Tablet should now be in "Droidboot" and PhoneFlashTool should list it on the top
9) In PhoneFlashTool click browse and select flash.xml from the "target_bin" folder
10) WAIT!!! until you see "Result okay" on tablet AND "Flash Sucess" in PhoneFlashTool
11) Reboot
12) When Android starts skip all dialogs (tablet is going to factory reset anyway)
13) Select Contacts from desktop and make 1 dummy contact
14) In the search bar type "####6020#" and then select your country
15) Tablet reboots and you are on stock KitKat again and should receive an update notice for Lollipop

Are you rooted? If so you need to "unroot". That can be done as simply as going into the settings of SuperSU and selecting - full upnroot. Or you may need to flash back to original stock...
Have you done the Update without problems?
Can i flash back original 4.4.2 without brick my YT2?
Edit: i have no ROOT

I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:
http://www.android-hilfe.de/thema/tu...ianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...
I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped:

and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml

Well, I got as far as extracting the original kk firmware, installing Intel phone tool and drivers with no problems. My issue is the tablet is recognized by the Intel phone tool while the tablet is in Android but when I reboot to fastboot it isn't.
This is in a virtual machine because I don't do Windows on hardware, only VirtualBox.
I may have to take an old rig and install Windows temporarily...
From my LG-G3 running Jasmine8.0/Skydragon Kernel 4.2
VitualBox maybe a problem, but why it works when in Lollipop OS and not in droidboot?
Firewall? ADB in developer-options enabled?
Try check your device manager in fastboot-mode if there is some "Unknown device" and install ADB driver...

Yea, I got it to work through VB. I went to upgrade and the upgrade failed and now it won't boot.
I'm going to try flashing the KK firmware again.
Edit: Flashing again now...

Lollipop won't update for me. I had a TWRP backup so I am right back where I was. Could it be the "country code" I saw in the instructions? If so what is the dial code for US? us?Duh, it brings up a selection box... Chinese but readable.

Root - no problem - Trigger 4
Update successful to YOGATablet2-1050F_S100067
Mine was a pleasant suprise.
LenovoPad YOGA Tablet 2-1050F
I already had installed Lollipop YOGATablet2-1050F_S100031 and rooted.
When advised there was a new OTA update, I did the following:
1. From within SuperSU Pro settings "Full unroot"
2. Reboot
3. Connect to PC
4. Run Lenovo Smart Assistant
5. Update was available, which downloaded to my PC
6. Lenovo Assistant began to transfer the update to the tablet, but ultimately (2 mins?) reported "Update failed"
7. Disconnected tablet from PC and turned it off
8. Simultaneously pressed volume down and power button, released volume key on vibration
9. Black screen quickly followed by the Android icon processing the update
10. Update successful to YOGATablet2-1050F_S100067
11. All data intact
12. Re-rooted using T4 (above.)
One happy camper! :laugh:
Oh, and Xposed-v67-sdk21-x86.zip successfully installed with this version!

Nexus 9 System is corrupt error after OTA update

Hello, going to put this here if it helps anyone else out. Couldn't find a post that helped (there may be I might have not looked hard enough lol)
So after leaving it for a week today I let my Nexus 9 WiFi only do the latest OTA security update, halfway through it came up with an error and on reboot got stuck booting with the little Android fella on his back with a message saying it was corrupted.
First thing I went to do was install the factory stock image, but this would not let me as I had not unlocked the bootloader (and couldn't as I couldn't access the Dev menu in android previously). Tried a few other things including factory wipe/fastboot/etc and this is what fixed it for me
Note: you need ADB installed (plenty of ways to do that on XDA)
- Download latest OTA here
- Connect tablet to PC with USB
- On the recovery screen bring up the menu (Power button + up)
- Select 'Apply update from ADB'
- [Windows] Bring up CMD and navigate to the update location (Hold shift + right click brings up the option to open CMD in that folder location)
- Type 'adb sideload (ota file.zip)' in brackets is the file name of the download (Copy the file name and right click into CMD/Paste)
- Tablet should update and be working after that
I also wiped Cache after installing the image, whether you need to do that I don't know. Tablet is now back up and running. I had factory reset the unit before trying this, so I don't know if it will keep data. I assume it would do as OTA don't normally wipe data.
Hopefully this helps someone
This issue pops up every month with corrupted OTA process.
Numerous threads with this solution posted in it.
Thanks for sharing.

(SOLVED) I install the custom rom successfully, but the phone only starts in twrp (Moto C Plus)

Hello, I have a problem that I've tried to solve in many ways. I unlocked the bootloader a while ago and installed twrp and a custom rom for my Moto C Plus. Recently I wanted to reset it and I did it through the cell phone settings reset option. It started with twrp and then I ran the rom and everything needed for the memory card to flash. The installation happens normally and without any errors and then I reboot the phone, but it always comes back to twrp.
And I can't use the commands by the buttons, only when I reboot the phone from the bootloader inside twrp (Reboot>Bootloader), and appears written right in the lower left corner "=> FASTBOOT mode. . ." and the rest of the screen is all black.
I already tried to install the original stockrom that I got with the IMEI of my cell phone in the program Rescue and Smart Assistant from Motorola, but whenever I try to install by twrp, it says that the zip file is invalid.
If anyone can help me I would be VERY grateful. I'm desperate for a solution.
-->My brother solved the problem!!! Thanks to him.
He used the rescue tool from the program Rescue and Smart Assistant to install the stock rom back (download link: https://www.motorola.com/us/rescue-and-smart-assistant/p). He said too that this error happens because TWRP "dies" and don't work anymore
Process:
1- Remove the battery from you device
2- Open the program Rescue and Smart Assistant, click in "Rescue" and then "Phone Rescue"
3- Plug the usb cable in your device (The program should recognize your phone)
4- With this, the program will give to you the informations and under this have a buttom to "Rescue". Click it and wait the installation
5- After the installation is finished, put the battery back and the device will turn on automatically, but you have to press and hold the power buttom to turn off and turn on again
6- After turning on again, boom!! Your device has been saved ans will start normally
