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
Good afternoon. I tell my problem.
Upon receiving mobile I decided to apply some improvements on your Android 6.0 system.
The first thing I did was root with Kingoroot, install Flashify to change the recovery; I do around here because they seem to have any accessible recovery. Once I install Titamium programs such as backup and Xposed and everything worked perfect.
I made a backup with recovery installed TWRP 3.0.2-0, a microSD 64 Gbytes and try to check it and restore the copy appears the message "Error extractTarFork () process ended with error: 25".
Since then switched on, enters a loop with minimal screen flash, short vibration and so on cyclically. I have made several attempts:
- I enter recovery (vol + power on) and try to install roms from PC with recovery sideload with adb sideload, but the downside is that I can not find any specific rom of this mobile and other snapdragon 210 Roma does not work.
- Another method was through Mobile Upgrade Q - Alcatel Mobile Phones, put it in Download mode (power on + vol up + vol down) in coming, but when connected to the USB computer when leaving the Download mode and enters the same loop described above.
I would be grateful for any help or idea they could think of. If someone could get a rom of this mobile in zip to install through sideload adb I think it would be the ultimate solution.
Thanks in advance.
Some tips:
Using Mobile Upgrade Q: Turn your phone off and leave to charge until full. Then use Mobile Upgrade Q.
Also, send me a PM and I'll give you the stock partitions and tools to flash them back from windows (No Mobile Upgrade Q Needed)
I tried with Mobile Upgrade Q
I tried to recover with the Mobile Upgrade Q, enters Download mode but jumps back to a loop with a little buzz that is repeated every 2-3 seconds.
The only way I can think of after many tests is to install the rom abd through sideload from the TWRP, then try to load roms other phones with the same processor but ultimately fails.
How can I send you MP?
Hello bro

Hi if u have twrp, installed I could send u backup of my pop 4
I had the same problem and I managed to unbrick the phone by using this solution I found on XDA.
Go into TWRP recovery. Then click on Advanced. Then click on Terminal and type
echo SYSTEMLESS=true>>/data/.supersu
After that flash SuperSu and reboot the phone. It bootloops once, but after that it boots normal again.
Need help? T.me/pop4uk

Hi,
i know its old but i need the Nonhlos.bin (modem) for 5051x marshmallow. can you please post it here ?
it would be a great help. thanks
Yeah I have a 5051X And its boot freezing not looping should I start a new thread or this gonna need a recovery image like in the OP. I have contacted alcatel supoort to see if they have the flash image but its sunday and I expect that they are closed.
I followed some instructions re rooting my 5051X which involved installing kingroot, obtaining temporary root then using flashy to flash twrp recovery onto the device, I could never update the recovery image and I assume thats because I havn't unlocked my phone yet.
Went to remove kingroot and find it cannot be uninstalled.
So i paid for Supersume (https://play.google.com/store/apps/details?id=darkslide.com.supersumepro&hl=en) and ran that to remove kingroot(i'll prolly reinstall later to follow the guide but dont really trust the application after my lockscreen changed on its own).
Supersume seemed to complete successfully.
Then I decided to reboot the device to see if root had disappeared again after reboot but am now stuck at the alcatel screen for the last 10 mins. Looks like i'm gonna have to pull the battery to shut it down, shame I only had it around a week.
Hi guys, I really need your help.
I'm new at this rooting stuffs and I tried to root my Oppo Neo 5.
I tried so many softwares like OneClickRoot, FramaRoot, and Kingroot but none seemed to work.
So I resorted to an app called oppo tools
It worked at first but I got really annoyed when my status bar suddenly colored to red when my phone discharges to 15% so I unrooted my phone and rooted back again. I really thought that was going to fix my problem but that's where the bootloop issue started.
I tried to flash some custom recovery zip but it failed since I only have a stock recovery.
But the thing is, I found a guide that says to rename the clockworkrecovery img to PG86IMG.zip.
So I did tried that and as soon as I flashed the zip from my stock recovery, my phone hanged.
I long-pressed the power button to restart and boot into recovery mode but nothing seems to happen.
I'll try to explain a bit more on how it looks when I boot my device.
When it boots normally (I mean not pressing the volume to enter recovery mode) it will only show the logo but when I try to go into recovery mode it will show the logo with a little text on the lower left portion "Recovery Mode"
Before I flashed the PG86IMG.zip, recovery mode was still working and the charging screen when off is working too.
but after I flashed the zip, every time I try to recovery mode the logo shows up with the little text but RECOVERY MODE isn't working. When I charge my phone it automatically boots up and shows the logo and text like it's trying to go recovery mode (I'm just trying to charge? It's going to recovery mode)
I tried using "adb devices" on cmd but it's not detecting any devices.
I'm really out of ideas guys, I know not all people use this model but what would be your suggestion?
A suggestion on how to fix this would really be appreciated :good:
I'm sorry I'm really new at this, please correct me if I did something wrong starting this thread. :angel:
@DeepBricked please confirm your problem, Boot-loop and can enter into recovery.

Oh, I'm sorry, I didn't notice.
Lately I can't access the recovery mode but now
I'm currently on Boot-loop and I can enter into recovery.
The ColorOS recovery mode only have limited function that I can mess around.
It only has the apply update, wipe data and cache, reboot, power off and system file verification.
As always I already did wipe the data and cache but nothing happens. Still boot-loop.
What should I do?

You made a soft brick, not to worry flash it with correct stock firmware, if the phone is in warranty than ask them to do flash, this will take approx 10-30min. If it isn't in warranty than you should try it own or else pay some amount and the rest they will do.

do u have access to recovery?? if u have, then u can just flash previous build without wiping data..
Think if you press vol+ vol- and power and then use the button combo to boot into TWRP you will be fine, takes abit of messing to get it right.

Did you try this solution? Did it work? Did you lose your apps/data?
Solved
Eventually managed to get onto twrp using adb (it was a bit of a statistical process... Didn't always work)
From there I just flashed cm 14.1 again, and it looks OK now
Thanks you all for the help!
Like I said earlier failed flash by CMxx doesn't overwrite TWRP, you can boot back into recovery just have to try a few times. Happened to me pressing both volume buttons and power switched phone off then I used button combo and it booted into TWRP.
Might have to grab a usb cable and use ADB to boot into fastboot. It happened to me and that was the only way for me.

Hello All
I find myself in a desperate situation.
I have rebooted to ffbm mode by mistake and my phone will not start.
I have just the white start screen with the wilefox logo...it does not get passed this.
I could do with some urgent help if there is anyone out there?...
Thanks
Update....I'm out of it...thank god...if anyone else finds themselves here then volume down and power button for a few seconds. Then you find yourself in the recovery mode where you can select reboot using the volume keys to navigate up/down. Rebooting then worked. What a relief!

Not working for me , help please ???, I had just unlocked my tab bootloader and flashed twrp recovery but instead of booting inyo recovery I booted into ffbm mode by pressing power mode , you are the only one who can help me please ??
I don't like to leave you high-and-dry...but I moved on from this phone already 3 years ago and its a distant memory.
All I can suggest is trying combinations of the buttons like. vol+ & vol- at the same time then press power and hold all 3 buttons.
Also on previous phones where I messed about and nearly killed the thing I found that holding the power button for AGES would eventually wake it up. It may be a waste of time but on occasions I found that just doing the same thing over and again eventually brought a result (although this is said to be the first sign of madness...so careful with that). Good luck with your endeavour...been there many times :S

May be I was wrong before that it is because of ffbm but here is the thing with which I had just suffered ... Yesterday just thought to go and unlock the device and root it with magisk, but when I booted into twrp , I found the twrp wasn't showing the device internal storage , so I searched on youtube and found that formatting data will help so I just did that rebooted again in twrp and it did work but while wiping other stuffs such as dalvik, cache , I accidentally wiped the system so I end up getting a lenovo tab 4 10 which can't boot anymore, And one more stuff is that my device is dm verity which is a biggest headache for me , I had almost 5 samsung phones and all rooted easily but the procedure of lenovo and their support is worst, I had decided to never go with any lenovo product in future but also can't waste my money on that tab : (
Btw ... Coming back to the topic while navigating to the device forum I found the o.p. has posted a system sparse image which can be used to restore the system but even after restoring it my device is not booting up only lenovo logo is popping up and then into fastboot mode, sadly there is no custom roms available for this device as I had also thought to flash the firmware using the guide but I am totally confused and scared about to not to do anything which will hard brick this device, I am still able to boot into recovery which I think is a strange think because after flashing sparse image it should be replaced by the stock recovery file, but as described no booting into system, I tried contacting in the xda forum but no one is replying , I even tried sending pm to the o.p. but no response .
I am conpletely newbie in this fastboot devices and the lack of support just sucks ,thanks for reading this and replying me if you have any suggestion from your previous experience then free fell to tell.

Maybe you have this fixed by now.. I searched around a bit about this and found this:
https://blogthetech.com/flash-file-lenovo-tab-4-10-tb-x304l-firmware-download-stock-rom/
Only one step I'm unsure about and that is "You will need to power off your device and connect it to the PC while off."
On my Wileyfox device (different device, I know) I need to power off and then press and hold all buttons (power, vol +, vol -) until device vibrates and gives a blank screen/no screen, this is how to boot into EDL mode on my device.
Your device maybe works differently, try both ways.
This is probably the best way of unbricking your tablet and here is the firmware file you need:
TB-X304L (WiFi and LTE)
TB-X304F (WiFi only)
Do I understand you correctly that you also have a dm-verity check issue?
For that you need to be booted up and have USB debugging on, tablet connected to pc and you type in this command:
Code:
adb reboot "dm-verity enforcing"
It will reboot and dm-verity check should by then be fixed.

Thanks for your effort, I had fixed my tab a week before by flashing the stock firmware but can you tell me what is the use of that dm verity commond.
And yes my tab is dm verity.

I should've given it another read, you have headache over dm-verity cause you want to root your device with custom recovery and stuff like that. This command line will not do you anything, not anything you want anyways.
On a Wileyfox Swift 2 device there was an bad uptade that made dm-verity check fail, this command was used to "reset" dm-verity. I assumed you had a similar issue but now I'm sure yours is a different kind of issue.
You would probably want to find a way of disabling dm-verity on your device.
Made one search for it and found this:
https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389
If it is only root you want you could get it with Magisk without flashing a custom recovery, you need the boot image of your device and you patch it with Magisk.
Then you flash the patched boot.img to your device. I believe this way works around dm-verity so is why I mention it.
