*.KERNEL linux version 3.0.36 i was trying to install CWM through mobile odin and ROM manager but my tablet was not supported so i downloaded build.prop editor from google play and changed it to some other cwm recognizable model viz. Samsung, nexus etc. When i was doing the above mentioned procedure, suddenly my tablet is coming up to bootloading and hanging there only and not opening

1)reboot system now
2)apply update from ADB
3)apply update from external storage
4)update rkimage from external storage
6)wipe data factory reset

8)recovery system from back up
i tried to do wipe data factory reset 2-3 times but still hanging at boot
i had not made any back up before this bootloop and also tried hard reset by pressing needle at the back please somebody help me to get rid of this problem and also tell me how to unlock bootloader thank you

Problem: I think I deleted my OS.
Here's what happened, i rooted my Samsung Note 10.1 using the clockwork mode with the super SU, then it went fine, I installed apps I got on net, then (after 4 months) i got a glitch wherein I cant copy/paste words, so I decided to reset to factory setting, then done. I thought of other way to root my tablet. I went to setting where it says Encrypt device, I started encrypting then interrupted it, when it rebooted it says that encryption interruped and I need to rest to factory setting then try to encrypt again, and asks to press the reset device, and I did. What happened is it keeps going back to encryption failure message and I keep on pressing reset device till it will only turn on with the SAMSUNG NOTE 10.1 Logo (the startup logo), then I tried installing clockwork mode again, and select wipe factory reset, and wipe cache partition and almsot all wiping option, so obviously i wiped my OS. I tried installing the Android 4.0 Ice Cream Sandwich following this guide on youtube Guide - How To_ Install Official Android Ice-cream Sandwich (cant post the link). When I followed it all it always failed in the end, and on my tablet it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again", and I cant connect to Kies and PC to do the firmware emergency recovery. Now I'm stuck in there and kind of thinks that I'm lost and totally broke my tablet. But still I can be in download mode.
Any brilliant answers guys. Thanks much in advance.
Back Up
Is a fast connection needed while installing the OS via Odin since it says Firmware Update Started?
And can anyone send me a links to download a functioning Android 4.0, Ice Cream Sandwich OS, please.
I have a a Lenovo Yoga 8 B6000. Im running 4.4.2 and after some fiddling, used Vroot to root, and subsequently went through some arduous steps to finally remove the Vroot and replace with SuperSu. Life was good. Then I got a little careless when removing some of the bloatware and ended up with a constant boot-loop problem. And of course, no backup. (whoops!)
I have been researching this the past 2 days for a workable solution and am reaching out for some more refined assistance.
Here is what I have done thus far:
When pressing Power + VOL+/- I get to the initial recovery menu which gave me: Recovery, Fastboot, and Normal. After selecting the "Recovery" mode, I get the "No Command", after which I pressed the power button one more time and got into the English recovery menu. I show
Android System Recovery <3e>
B6000_A442_001_026_141117_WW_WIFI
Reboot System Now
Apply Update from ADB
Apply Update from SDCard
Apply update from Cache
Wipe data/Factory Reset
Wipe Cache Partition
I attempted to wipe the cache, followed by Wipe data/Factory reset. Following this procedure, I remained in the boot loop.
I installed ADB Flashtool drivers for WIN7 and attempted to use flash tool which was also suggested on this site. I got a 4.2.2 ROM "B6000_A422_000_059_131219_WW_WIFI" from a russian lenovo forum site to use with the flash tool and because the tablet continues in boot loop when starting, there was no loading of the ROM from that method.
I put the rom on an SD card and went into recovery mode. The ROM was not visible by the recovery menu (By that I guess the Apply Update from SDCard is looking for a specific file extension, which is not present).
I may have tried a few other things which are not popping into my head at the moment.
Im kind of at a loss and looking for any ideas from the gurus out there on how I might be able to get any kind of ROM to flash onto my B6000 and getting it up and running again.
Thanks
I was able to successfully fix the Yoga 8 tablet by using the instructions here:
//aluk4rd.wordpress.com/2014/09/08/an-easy-guide-for-restoring-your-stock-4-2-2-firmware-on-your-lenovo-yoga-tablets-8-and-10-b6000-and-b8000/
The trickiest part was getting the Mediatek driver installed. I use a dual booting MAC with WIN7 and sometimes there are some kwirks when operating in WIN7. However, the results of the instructions brought my tablet back to life, as well as downgrading to 4.2.2
Hi engineer2loggie,
How did you get that firmware? Can you tell where can I download it?
Thanks.
has anybody found a solution to this? im stuck with the same problem atm
Recently, my friend wiped his tablet including the internal storage and when he tries to reboot to the system, TWRP says "No OS Installed". I then decided to flash a rom to his device, it was successful according to TWRP, but when I boot into the system, it goes back to TWRP. So now i don't have anymore ideas but if anyone can help me i would greatly appreciate it ! All i want to do is to unroot his device...............

Hello everyone! My Serioux Surya Reaction tablet is stuck at the moment where it shows the Serioux logo. It doesn't auto reboot, I can enter in system recovery and i tried wipe data and cache but none of them worked. The tablet worked very good untill today when I factory reset it, but before that I transferred every app to system/app because I wanted the apps to remain after the reset. After reset, I saw that when I tried to enter in Chrome, MxPlayer or Sopcast it appeared that files are corrupted, so I installed Titanium and uninstalled these 3 apps. After that I rebooted the tablet and the thing with the logo happened. I can't find the firmware for this version of Serioux to flash. Can you please tell what can I do now?
