Please help : rooting failed & TWRP recovery mode touch bot working

Hey Harry, even I'm in same trouble ... touch is not working in TWRP recovery mode.

Bought this tab just a couple of days back and just wanted to root it. Tried the rooting instructions (followed all the steps) using the Crystal_Root.zip on this forum but it didn't work; seems like SU binary is not getting pushed. So I thought of installing TWRP to try rooting from same and now I'm stuck with this dead recovery mode. :crying:

Could someone please help on how to get back the stock recovery and/or how to root this tab via some flashtool / adb using PC.

Please help !!!!

info related to service center

I emailed karbonn customer support and they informed me about the status of my tablet.

email id-

info@karbonnmobiles.com
[Android General] fuser-invent:
@ anandisrocking007 - You'll probably need to go into the build.prop and change the default location to your location code. That would be my guess on why you are getting a time difference but I'm not 100% sure. However, if you do that you might loose some market compatibility.

@ Prakash_Shrd - Read the scripts in the ADB package I linked to. It's pretty straight forward. You push the flash image file, push the recovery and then overwrite the old recovery with the new one. It's possible that your tablet's company has released a new batch of the tablet with different hardware, Ainol did that on multiple occasions with their tablets. People with old tablets and new tablets should post their build numbers, which is probably part of the serial code on the actual hardware, and the full kernel info that can be found in the system settings. If the kernel is different than the older models then I would suggest that nobody attempt to flash TWRP.

-----

Also, on another note, the reason why I repackaged the TWRP files to be bootable as stand alone files was precisely for this reason. The TWRP's that I provided should work without having to flash them, you extract the file from the zip and then just place it on your external SD card.
[Android General] Prakash_Shrd:
@ fuser-invent - thanks for your prompt reply.

I had already tried ABD method using the 'recovery.img' from 'karbonn_st8_stock_recovery.zip' but that didn't help; please refer to attached snap. Also attaching snap for tab's kernel/build version.

Since I bought this tab just couple of days back, I guess it might be true what you said regarding change in hardware by Karbonn... on back left corner of tab it says 'ver2' after S/N. Even the rooting didn't worked for me when hardly anyone else had complained about it.

Kindly let me know if you would be able to help me with this issue ... anything like a flash-tool or manually editing/replacing any files using ADB shell. Kindly let me know if I need to provide more info.
[Android General] fuser-invent:
We'll have to wait on someone with an older version to post the kernel info but it looks to me so far like I am correct and this is a new version with new hardware. What will need to happen is that someone else with an untouched stock tablet will have to dump the partition images and post them here. Then you should be able to use the adb flash package to write the stock recovery back. I don't do the TWRP's for these tablets, so if anyone with a version 2 wants TWRP they will have to leave a post in the Karbonn TWRP thread. He will need the boot.img from the new version of the tablet to be able to create a new TWRP for the device.

If you can't wait for this to happen then I would suggest sending the tablet back to the service center, however, I'm going to suggest again that every single person who reads this thread contact the service center and request that they release the official stock firmware package for both version of the ST8 and ST10. It would be way easier to fix problems on your own if that were released instead of having to send the tablet in and wait weeks to get it back.

Smart Tab 8 v2 Root/Rom Dump

Does the root method work on the new v2 of smart tab 8.....if its working i ill make a rom dump asap...............i ill have my tablet delivered to me by indiatimes shopping by 16-18 july 2013......

Need a reply......if root works i ill use [EASIEST WAY ROM DUMP] ROM dumping method for any phone. - xda-developers for dump......

[MENTION=4959164]fuser-invent[/MENTION]: also if root method is not working tell me what should i post to try other methods for u to judge and suggest one....

like chipset etc/build prop..........thnx

and is rom dump possible without root,please enlighten me
[Android General] Prakash_Shrd:
[MENTION=4795284]2012katas[/MENTION]: - As mentioned in my last post, I can confirm that the root method mentioned on this forum doesn't work for the new ST8 ver.2. I had tried that and failed. Later flashed TWRP recovery (to see if that helps with rooting) and ended with non-responsive TWRP recovery mode. My tab still though boots normally. If only there is some way to root it without recovery mode (adb /flash tool).

[MENTION=4959164]fuser-invent[/MENTION] / [MENTION=4747885]ankitdaruler[/MENTION]: Could I please request you to update this info on original post (i.e. first page) regarding compatibility issue of ST8 ver.2 with current rooting/TWRP methods. This could help others avoiding my fate.
[Android General] fuser-invent:
I haven't seen antkitdaruler around for a while but I did update the original posts for my custom and stock+ roms.
[Android General] Ozadroid:
What the hell is version 2??:confused:

The screenshot looks same as mine except the build dates i.e. 20130218.
[Android General] fuser-invent:
Is the Kernel the same? With the Ainol Crystal each version just had minor changes in hardware that were reflected in the kernel, like a different wifi chip or wifi configuration, different g-sensor, etc. With the Ainol Fire they changed screens, so when people tried to flash the old firmware to the new tablets the screen got messed up and was extra dim/dark. If the kernel is the same on the two Karbonn versions though, it wouldn't make sense that there would be a problem with TWRP or flashing zips or ROM's.
[Android General] Ozadroid:
I think may be they changed the thouchscreen driver for ver2 coz in first release the screen is all messed up. N figuring that i suppose people r not getting the touch to work in twrp.

I think changing the kernel in recovery.img would do the trick. But i dont hv pc to do it. So anyone else hv to do it or else hv to wait for a month.
[Android General] fuser-invent:
Any chance you'd be willing to do a short tutorial on DragonDev's on how to swap out the kernel? Or better yet, if you have some time, we've been looking for someone to write up a tutorial on how to port TWRP to Amlogic tablets that don't have it yet.
[Android General] Ozadroid:
Sorry bro i am very busy these days.

And even if i spare some hours to write a tutorial, i dont have a pc :(

Though changing kernel in recovery is very easy.

Decompile the recovery.img with dsixda kitchen. Change the kernel n recompile. Done.
[Android General] fuser-invent:
No problem, I definitely understand being busy. If you ever get any free time and feel like sharing, we are always looking for good people to write about what they've learned over there. The goal is to get a lot more user friendly guides for beginners and get more people into android development.

Good News: Root on Karbonn ST-8 Ver 2

The problem was Crystal_Root was mounting system as UBIFS whereas in the new version the filesystem is ext4

OLD UPDATER SCRIPT:

mount("ubifs", "UBI", "system", "/system")

changed to

NEW UPDATER SCRIPT:

mount("ext4", "EMMC", "/dev/block/system", "/system")

Karbonn ST-8 v2 Stock ROM Dump

For a complete dump head to : https://app.box.com/s/sex93bpevu6c0qjvbhkl

Use hjsplit or similar tool to get system.tar in a single tarball from system.tar.001 and system.tar.002...

Also this dump is bloat free with a few exceptions trimming it down to 440mb which would have been 540mb otherwise
[Android General] rifad20:
Thanks buddy...just got the product this evening..I already searched for rooting ...and found this page before ordering the tab..I downloaded the root file...so I just need to flash it thru stock recovery right??and can I use the swap external-internal and other files for St v1??
[Android General] fuser-invent:
So if v2 is EXT4, does that mean your firmware is JB 4.2?

Mirrors for ROM Dumps and Backups.
[Android General] 2012katas:
[MENTION=4959164]fuser-invent[/MENTION] : The firmware version is 4.1.1

[MENTION=836334]rifad20[/MENTION] : I have only tried rooting till now....which works with the zip i had attached...if u want to swap internal and external data u can try GL to SD which i use for games.....cannot comment about vold.fstab from ver. 1 and dont flash any roms from ver 1 :angel:
[Android General] fuser-invent:
I'm a little confused, your new version of the tab is running EXT4 but it's not JB 4.2 and you still have two internal partitions instead of one large one?

Anyway, you are right that you can't flash any of the files for v1 because they all use the UBIFS in the updater-script. Chances are you might be able to edit the script to flash a custom ROM because my packages don't flash any image partitions and only flash files to the system folder. You'd have to re-script it for the stock recovery though since there is no TWRP for this new version and there would also be a risk. So this would be something for experienced people only.

On another note, if anyone noticed, one if the files in that folder I linked to is supposedly the official ST10 firmware made to be used in the AML USB Burning software, aka. flashed via USB. If it works for the ST10 that means that those users could unbrick even very badly bricked devices and also create an SD card rescue image for soft bricks. Someone send me a PM with the link and it looks like maybe someone hacked the Karbonn site and downloaded a bunch of the firmwares that they didn't officially release but I really don't know what the story is.
[Android General] rifad20:
I have a doubt. Why we need a set cpu when our cpu's are already clocked @ 1.5GHz...as u mentioned above if 1.2 is only needed for hd games, why even bothering for doing such things??are we making any changes in gpu also??its a doubt...
[Android General] fuser-invent:
Thanks to 2012katas I got to compare the system folder between the v1 and v2 Karbonn ST8 Tablets. There are major changes so I can now confirm that, even if you were to change the updater-scripts for the EXT4 partition format, neither the Custom or Stock+ ROM will work. Most of the actual apps and framework files are different. They've changed the wifi chip from BCM40183 to a BCM40181, changed the g-sensor and the way that it is configured, looks like audio is being handled differently as well and importantly isn't it's not even considered to be the same device anymore:

The old Karbonn ST8: ro.product.board=g05_n1bref

The new Karbonn ST8: ro.product.board=g05_s86pbtref

With the change from the Wifi BCM40183 to a BCM40181 chip it also means that this v2 tablet should be built in wifi only instead of built in wifi/bluetooth.
[Android General] anandisrocking007:
Hi fuser-invent I want to ask you the name of the document viewer app that you have added in the stock plus and the custom ROM it is not there in the original ROM of Karbonn ST10 I also can not find it in the system/app folder how do I get this app.:confused:
[Android General] fuser-invent:
Do you know what it's called? Unless it was part of the additional apps package, it would probably be in data/app. That's where a lot of the extra apps go because it allows them to be recognized and updated by the play store market.
[Android General] anandisrocking007:
I searched for this app in the system/app and data/app partitions but to no avil it is only present in your custom and stock plus roms and not the original by the help of the recent app function i found its name to be document viewer i searched the net but could not find this app anywhere i have posted this apps screenshots below hope you can help me thanks in advance......:fingers-crossed:
[Android General] fuser-invent:
I did not put any free-standing app like that in the ROM. My best guess would be that it is integrated into whatever file browser you are using.
[Android General] anandisrocking007:
Well I get this app running as soon as I install the PLUS ROM and the CUSTOM ROM I did not install any apps in it well..... thank for replying

---------- Post added at 01:03 AM ---------- Previous post was at 12:59 AM ----------

Finally I found it it is a system app called document viewer 4.2 it does not have any icon and is 10 mb I goes the person who gave you the romdump had this in his ROM
[Android General] fuser-invent:
Interesting, I wonder which apk it is.
[Android General] rifad20:
when vl come the custom rom for ver 2 ??
[Android General] fuser-invent:
,

Not sure if it will or not, it will take a lot of time and work to get it done. All together the ST8 & ST10 Custom and Stock+ ROM's have had 28,406 downloads as of today and I've only received $5 total in donations for all those downloads. That isn't much incentive to continue developing for Karbonn devices.

On another note the official ST8 stock firmware package is in the ROM Dumps and Backups folder. I'm assuming it is for version 1.
[Android General] rifad20:
i have a problem with swapping internal external..everything works in it like showing storage and everything...but when i move the app to sd and restrt the tab, the app isnt showing...help me...
[Android General] Ozadroid:
Fuser. This is a free community. You shouldn't be asking money for what you do here. My TWRPs have more downloads than your ROMs. If people think they can donate they will donate. Its your free will to develop or not to. But if u want money against your work you should work in a company.
[Android General] fuser-invent:
Your TWRPs take far less time to develop than ROM's do but people who can should be donating to you as well. I'm not saying anyone has to donate but the attitude that developers should just work for free is why so many developers end up abandoning devices. We invest a lot of time and have expenses like hosting costs and hardware failures/upgrades. It's a different story if you are developing a ROM for a tablet that you already own and just sharing what you are doing, but when people are asking for your time and energy to develop for a tablet that you don't own, it is nice to donate if you can. I've been told that it is hard to donate through paypal in India for a lot of people, so I understand that problem but the idea that you should donate to a developer if you have the ability too is ridiculous. Especially for something that made your device better and you use on a daily basis.
[Android General] Ozadroid:
Lol, twrp is easy to make? That too for a device whose sources arent released!

First i had to search for a similar device n then edit its device folder to make st8s device folder. Just try it. U'll see how difficult it is to make a core program without a device folder. Modding an already built rom is just a matter of few minutes/hrs. Name the mod n i'll give it to you in your ROM in 30 min. YoU just need copy paste the files n edit some configs.

I have ported miui for my p500 too but i dont ask people to donate for my work though there are potential donaters present. I just ask whoever can shud donate. I dont say i wont develop until u pay me for my time n hard work.

I will say it again. It is a free community, develop if u are interested. Dont develop if u think u'll get paid!

Ps: and if you really want to get paid. Make your downld links premium. People will HAVE TO pay you if they want to use ur stuff.
[Android General] PRRash:
Guys, U both are the most possibly only potential developers this tablet has :) Dont get things wrong ,, What fuser is trying to tell is that, when u own th device, develop for u'r case & sharing is different when u dont own the device :) Donation is a way of showing gratitude for the efforts & time developers put forth,, It's a way to keep developers motivated & the least thy can expect in return... People who can afford, consider donating atleast little, for those who cant simply thank developers & keep the thread alive :) Peace :beer::beer:
[Android General] fuser-invent:
Exactly this. Showing gratitude whether it is through donations or just a thanks is what keeps developers motivated. If no one donates or says thanks but just downloads, you wonder why you are paying for hosting, buying hard drives for more space and spending your time. So thanks PRRash! :beer::beer:
[Android General] Ozadroid:
I am not saying asking donations is wrong. But asking it again and again like its your right to get donation is wrong. And i havent seen any of your posts on which you did not get likes. So you should be more than motivated.

And you should make your downloads premium. That way you'll get money deserved for your work.

[Android General] AnkitChowdhury:
Ok guys I am finally ready to make the Flashable Stock Rom for Karbonn Smart Tab 8 & 10. But to make this I really need your help. Someone HAS to provide me the ROM Dump of these two devices. Because If I use my ROM Dump dongles won't work. So please follow the ROM Dump Tutorial I'm providing here. It's easy and would help a lot of people. It's even more important than CWM because even with the stock recovery this ROM would be flashable. And once I get hold of the Stock ROM I'll make Custom ROM's too. But I need your help.

ROM Dump Tutorial
[Android General] AnkitChowdhury:
Rom Dump for ST10 is not required because I have fixed the dongle issue. And the Flashable Stock ROM would be ready very soon.

Now the important question is who will test it?? Is there anyone who has bricked their ST10?? Please comment here so that we could move further in development.

If the Stock ROM(It should for sure) works the next thing will be the Tablet UI as one of my friends is working on it. So testers please comment here if you want development to continue.
[Android General] Ozadroid:
bro the first thing is full fledged recovery.

Yes, the rom can b flashed with stock recovery. but how would you clean the /system partition? because if u cant clean the system partition you r gonna get a corrupted /system !

moreover even if u manage to clean /system somehow what is the guarantee that u make the ROM work in the first go! so first you need a backup in case everything gets failing!
[Android General] AnkitChowdhury:
It is possible to format the system even without CWM. And if you check the threads for Ainol Crystal earlier most ROMs were flashable through Stock Recovery Only. If the Stock ROM works which it should, we can actually go for Custom ROMs because it will more or less be similar to a backup created through Recovery. As this zip doesn't have the boot.img or the bootloader there is no chance of a hard brick.

Anyone who has messed up their tab using Chainfire or something else might go for it. Please comment over here so that I can send you the file.
[Android General] AnkitChowdhury:
And yes my Developer friend who has made this Karbonn Stock Plus ROM would be here to troubleshoot the problems if it occurs.
[Android General] Ozadroid:
Hmm okay the chances for a hard brick are negligible, but are you sure the zip would work properly?

and if you have the META-INF folder i can get started with cm10!
[Android General] AnkitChowdhury:
Ya I'm pretty sure because it's basically the Stock ROM which is deodexed ,init.d is added and few bloatware is removed. The one who has made this flashable ROM is a Dev working for Ainol Crystal for quite some time. And he has packed it into the zip and made it flashable through Stock Recovery. So I don't see why it wouldn't work. And yes you can get the META-INF folder. It'll be better if you download the Stock ROM completely.

I'm PMing you the link. And this is for ST10 so do not flash it if you own ST8.
