I finally won against the system.img file ! :D I can flash it with Phone Flash Tool but I have got an other problem... I can't boot android too..

When I flash with all the files with flash.xml, I have got this message :

Is it the problem or not ? How could I use back my tablet normally ?
[Thinkpad Tablet General] LyMougli:
Bootloop, problem mounting system

Look at it, the 2first pictures are with PhoneFlashTool, and the 2 others are with your CWM. The problem seams to be a bootloop, and it seems to come from the fact I can't mount system.img. Why can't I mount it ? How could I solve this problem ? Thanks for your help
[Thinkpad Tablet General] vampirefo:
You can't mount system cause of the garbage PhoneFlashTool, it damaged your tablet, just like it has to others, only advice is to never use such a horribly designed tool. Only use fastboot, adb and or custom recoveries to modify partitions

I don't have your tablet, so no way for me to give you a step by step how to fix it.

I posted a guide for dell venue 8, you can look at it, make changes needed per your tablet.

My screen name there is TK.

[Thinkpad Tablet General] LyMougli:
I don't know how you change the partition in the file... is it possible to do it for me ? I joined partition.tbl as a zip file
[Thinkpad Tablet General] LyMougli:
moreover, my device is not recognized by adb
[Thinkpad Tablet General] vampirefo:
Well, seeing you don't have a system how could adb possibly work?

You need to fastboot your system into place.

Hello

Failed on Yoga 2 830F
[Thinkpad Tablet General] ronotron:
Dual Boot

I bought myself the Yoga 2 8" (android 4.4.2) with the intention of Rooting it and setting up dual boot, so i can run windows when i need to.

Now i HAVE the device I've realised that there probably wont be a lollipop update for it (since lenovo have released an lollipop update list and none of the yogas are on it), there is no dedicated XDA forum for it and there is so windows rom available. What do you guys think? is any of this likely to change? will there be development on this device to such an extent that we'll see custom roms for it? and dual booting? I got it from Amazon yesterday, and i'm already considering sending it back to order the windows version.

the android rom on it is horrible, bloaty and IOSy. :(
[Thinkpad Tablet General] LyMougli:
When you say

"then run my recovery script

#!/bin/bash

./fastboot flash /tmp/recovery.tar ./recovery.tar

./fastboot flash /tmp/recovery.fstab ./recovery.fstab

./fastboot flash /tmp/postrecoveryboot.sh ./postrecoveryboot.sh

./fastboot flash /sbin/partlink recovery.launcher

./fastboot oem stop_partitioning"

Where and how do I make this ?
[Thinkpad Tablet General] LyMougli:
oh and for this :

adb shell

fdisk /dev/block/mmcblk0

p

Once you partition and flash everything, boot to cwm recovery and resize partitions, use resize on cache, data, system, you need to umount cache first, cache may not need but try anyway, before reboot remount cache.

I made adb shell , fdisk... and p, but what do I have to do to partition 1.5g or 2g ?
[Thinkpad Tablet General] vampirefo:
Your partition.tbl already shows system as 2GB.

My fdisk looks like this.

If it's already good, what do I have to do to be able to mount system back and use android back ?
[Thinkpad Tablet General] vampirefo:
I don't know that you can, you used a tool that messed up your system, so you may never be able to get the tablet to work.

You have not posted any info showing that you have even tried to fastboot your system, without any info I can't even guess what to tell you, if you want to take pics or copy and paste your fastboot commands showing exactly what you are doing, I might be able to help might not.

In the end it all depends on how messed up you tablet is.

do below and show pics or output of your terminal.

fastboot oem start_partitioning
fastboot flash /tmp/partition.tbl partition.tbl
fastboot oem partition /tmp/partition.tbl

fastboot erase system
fastboot erase cache
fastboot erase config

Worked great for me on my 1380f. I use Titanium Backup to remove YouTube; then I installed Xposed, YourTube, and Adaway; then I changed my build.prop to 5.0.1; then I installed YouTube from the Play Store. 1440p worked on one video, then it just stopped working. I can get 1080p now, but not 1440p - not sure what happened, but I don't have the patience to continue to mess with it.

Thanks for the great guide!
[Thinkpad Tablet General] LyMougli:
Look at it, everything seems to be alright, there and on the tablet.

PS : I wrote "flash fastboot droidboot.img" because i don't have any fastboot.img file, just a fastboot.exe, so I think droidboot.img is the one which is needed
[Thinkpad Tablet General] vampirefo:
Now start tethered recovery

make sure mmcblk0p6, mmcblk0p8, mmcblk0p9 are correct for your cache,data,system

adb shell

umount /cache

e2fsck -f /dev/block/mmcblk0p6

resize2fs /dev/block/mmcblk0p6

e2fsck -f /dev/block/mmcblk0p8

resize2fs /dev/block/mmcblk0p8

e2fsck -f /dev/block/mmcblk0p9

resize2fs /dev/block/mmcblk0p9

mount -t ext4 /dev/block/mmcblk0p6 /cache

reboot

if you can't get adb shell to work in recovery, it may be due to the adbd file used, its for dell venue 8, you may need to use one from your tablet.
[Thinkpad Tablet General] LyMougli:
I can't find any adb file for yoga 2 on the net, i found an installer but no adbd file. Moreover, look at what I show on the picture I join, this is a photo of the tablet when going into your recovery
[Thinkpad Tablet General] vampirefo:
It's in your boot.img, recovery.img and fastboot.img if you don't want to put any effort into fixing your tablet then neither do I.

I am done here.

fastboot drivers?

Can't get past "fastboot cmd waiting..." I'm assuming this has something to do with me not correctly installing the fastboot drivers. I just used a tool to install adb and the like, so what what do I need to do to get the fastboot drivers working? Thanks.
[Thinkpad Tablet General] leechseed:
Did you install the lenovo drivers included in lenovo suite?

Check device mamager for missing drivers.
[Thinkpad Tablet General] Falv:
I did install the drivers that came in the suite and adb seems to be working. Here is some pictures that might give some clues as to whats wrong.

Hi bodivas,

i had a strange problem with my 1050L.

After rooting correctly the tablet with social-design-concepts procedure, on the third reboot of the tablet i lost the gsm functionality of the tablet. Actually it says "no sim card" (obviously i've tried with a ton of sim card, no luck).

Any idea about this issue? No other modification has been taken except the root.... and it worked flawlessly after a second boot, but not after the third...

thank you all

Missing zip

Hi guys,

Just bought a 1050F and I'm trying to root it but when I get into the custom recovery,I can't see the zip I put on the card.I've tried putting in a few different places but it still doesn't show up in the recovery.Any ideas ?

Cheers Vinny
[Thinkpad Tablet General] Paran[dr]oid:
Maybe bad download of the zip or wrong end (example. zip)

Try to put your zip in the intern sd
[Thinkpad Tablet General] Vinny1967:
Thanks for the reply.I've checked everything.Tried renaming the zip but it still ain't showing.I'm no newbie to rooting but this has me stumped.

Vinny
[Thinkpad Tablet General] Paran[dr]oid:
Have you installed first the temporary cwm?
[Thinkpad Tablet General] Vinny1967:
Yeah I got the cwm installed without any problems.It's just the zip not showing up.
[Thinkpad Tablet General] Paran[dr]oid:
[MENTION=3961688]Vinny1967[/MENTION]

Try to redownload the zip. Check md5 sum > put it on your external sd card( not in a folder) > retry flash. If don't work i would try to reflash the custom recovery.
[Thinkpad Tablet General] Vinny1967:
OK managed to get it done.I fully charged the tab,turned it off and left it for about 15 minutes.Turned it back on and tried the rooting processe again and this time the zip file showed up.All done now.Thanks for the help Paran[dr]oid. ;)

[Thinkpad Tablet General] youngblood68:
Hello , I got mine today , anyone knows how long this tablet takes to charge fully ? I have been rooting all s and note Samsung phones but I have never rooted this tablet so I am a bit carefully , could anyone who have the patients to show me how to root this step by step so I don't end bricking it? about the charging? is this normal its on 20% and saying connect your charger ?? and it is connected and charging but not saying that its charging?? I have the 2 pro 13 model
[Thinkpad Tablet General] Falv:
Hello. First Ill let you know i have the 10" model so things may be slightly different. About the charging I found the first time took an eternity and in general it takes a long time to charge. Make sure you use the wall charger it came with as it'll be faster than say your computer USB port. If you get a battery widget to track the charging to make sure its working and track the time it takes. (I really like battery widget reborn). The app says average 4 hours from 0 for mine so I imagine yours would be even longer as the battery is bigger I believe.

I can make a summary of the rooting method I used if you like. The guides here are pretty decent but I can go in depth and troubleshoot you if ya want. I wont be on until tomorrow afternoon so if your still wanting some help msg me and I'd be glad to. Good luck rooting!
[Thinkpad Tablet General] Mittul Shah:
I rooted the device. Root checker shows the device is rooted but non of the rooted apps work like gltools..

I think the root wasnt done properly first time so i rerooted it but there is the same issue.

Start the .bat on PC, put in first ACCEPT then T3. Your Yoga will restart in temporary cwm. After that install the Super Su. Zip. Done!

Im somewhat stuck with this part of the description:

How do I check? And how can I fix it, if it didn't install correctly?
[Thinkpad Tablet General] Paran[dr]oid:
Your problem is that the tab wouldn't recognized right? Maybe you need different drivers for 8.1? Install "Lenovo Smart Assistant" on PC and give it a try again. ( It installs needed driver)

I'm looked a bit around for your problem. It seems that win 8.1 have problems with fastboot/adb . look here for example:

[Thinkpad Tablet General] amourtin:
Hi

Tnx, My problem resolved and rooted my yoga 2 8 .
[Thinkpad Tablet General] fastmov:
Finally - SUCCESS! Thank you!

First of all - thanks you so much for all your time and will to help! You rock!

Since I am stuck on too many points again (Lenovo Bootloader has no "Fastboot" - Option as mentioned in the description and I dont know what to execute on the PC precicely) I will give it a try on a Windows 7 PC on Monday. I don't want to do too much on a "Trial and error" - basis and I don't want to waste your time with unnecessary questions.

But it looks to me as if you spotted the Problem! I would NEVER have thought of my PC being the problem, since it displays the content of the android filesystem properly and starts the procedure. What a bastard! :)

Update: Success!

But Murphy's Law totally got prooved. I used completely different PC's. Connected the Tablet to the Win7 PC, it did Charge but not connect as a device. I tried it on another PC (with Win 8), it did Connect as Device. I Fumbled around on the Win 7 PC, deactivated Firewalls, Rebooted, whatever... nothing helped. I went back to the Win 8 PC to try and root it with the "Extended Method" - but now it didn't connect as a device here too? :eek: In the end it was a defective USB cable which caused the last problem. I replaced it and - TADAA!

From then it worked like a charm and I am so lucky about the root access!
[Thinkpad Tablet General] Falv:
Also had basically your problem too. What did fix it for me on windows 8.1 was when your tablet was running the fastboot launcher saying "waiting for device" I had to go back into device manager and reinstall the adb again when droidboot was waiting. Then it started up and all went smoothly. Hope you can get it working.
[Thinkpad Tablet General] ellentracymac2:
Also wondering and hoping there is progress here.

Very much hoping there will be an English version soon.
[Thinkpad Tablet General] fastmov:
And I am f***ed again.

Lenovo decided to roll out an absolutely meaningless update, which they announced as "important". It did absolutely nothing - apart from taking my root-permissions away. The first 1000 times I klicked on "Ignore" but finally I installed it because it nagged me. Bad choice.

SuperSU has an Option to keep itself "alive" (however it was called) but unfortunately that didn't work obviously.

Now I can't repeat the former successfull steps - again I am waiting for the device forever like described before.

WIN7

Lenovo Smart Suite says I have the latest Drivers

No Firewall

USB-Debugging enabled

Good USB-Cable ;)

The one thing that catches my Attention is, that I have one unknown PCI-Device in my Device Manager. (A Lenovo ADB Device is present too). It disappears when I plug out the tablet. Could this be the Problem and where do I get the needed Driver? Auto Update Fails and the Lenovo Smart Suite - is not adressing that. Uninstalling and searching for new Hardware didn't help.

Oh and special "thanks" to Lenovo, I will never buy something from them again as they put too much effort in harming their customers instead of being helpful. :mad:

[MENTION=6538168]fastmov[/MENTION]

You solved the problem?
[Thinkpad Tablet General] tejaswy:
Dear Fastmov,

I have eperienced the same problem, but it is fairly easy, if time consuming, to overcome. Did you try the intel flash tool method? After the update, none of the method's worked but the Intel flash tool method worked like a charm.

As for the cable, try to use the original lenovo cable with a USB port that is directly on the motherboard. This also makes a lot of difference. I was unable to root my tablet (fastboot drivers not installed correctly error) when I connected the tablet to the PC via a USB hub.

I am on a Win8.1 system, and have had no problems with it so far.

Also, I agree with the not wanting to buy lenovo products bit. While they do make decent products, love from XDA is seriously lacking, and it is too painful to find any ROMs. Not that I do run custom ROMs but, having options is always great.

Do post if you have sorted your issues out.

I am Kind of proud of myself, I fixed it by myself.

It came to my attention, that my device Manager displayed a Problem with the Lenovo when it was in the rebooted-state. (After selecting that T3-mode).

The driver was working during normal operation though! Plus I could not install the original Lenovo drivers!

What did the trick was to use the Lenovo ADB Driver from the existing list of Drivers. (Not by selecting the driver file but the device)

The PC gave me a warning that everything was about to explode, but as soon as I installed that driver, the process continued and I ended with a success.

I hope that hint is useful for the developers of the rooting tools.

And thanks again Lenovo for costing me hours of my life.
