Lenovo IdeaTab A2107A-F - Android General

I am starting this thread to hopefully encourage discussion on the Lenovo A2107A-F tablet variant.
I am aware there is an existing thread on the A2107 here:
http://forum.xda-developers.com/showthread.php?t=1982334
but that thread is concentrating on the A-H (dual sim + wifi) variant which is somewhat different from the A-F (wifi only).
So far I have not found any custom rom development, which is disappointing as the stock rom leaves a lot to be desired IMHO. While the current OTA update is fine for web surfing, reading emails etc, HD video playback (particularly YouTube HD) is very poor. Also the recent OTA update forces an optimization of apps on bootup which leads to long boot times
You can root and install CWM by following steps 1-5 from the 1st post here:
http://forum.xda-developers.com/showthread.php?t=2044496
Note that "-Update 3-" mentioned in the post does not appear to work for the A-F model!
So, has anybody any leads on possible development on this tab?
Any tips on improving performance?

My first tip:
If after installing CWM you cannot get to the CWM recovery screen after powering down the device, look for for the file "/system/reboot-from-recovery.p". If it's there, either delete it or move it to some other place. This file restores the default recovery on a system reboot.
I got bitten by this a couple of times

Thanks for starting a separate thread for the A2107A-F. I'm new to Android devices and just got this one two weeks ago. I'd like to get rid of several of the apps that I have no use for and from what I understand that means I have to root it. I got lost in the details of the other thread, but I tried reading all of it. I'm on Vista and somewhere along the line I installed one of the suggested ADB drivers via PDAnet. Device Manager is showing Android Phone and under that Android ADB Interface. I wasn't sure if that matched closely enough with the step-by-step threads since I don't really think of the device as a phone, so I've been holding off on going further. I've tried using a few other drivers that were suggested in the large thread and some other threads, but Vista always tells me the current driver is the most up-to-date one.
Do you know if it's okay for it to say Android Phone rather than something else?
Thanks. I've got some other questions about the specifics of some of the other steps, but this is probably enough to get started.

My apologies in advance if my posts are too long and my questions are too basic for these forums. Feel free to point me somewhere else based on what I'm asking for. I'd honestly appreciate any leads towards my goal of getting rid of the bloat on this device and making it more responsive. (Wow! The portrait to landscape lag is really bugging me now after reading around here).
Anyway, my primary purpose is to remove the seemingly unneeded programs, services and widgets that come with the tablet. Maybe I'm just ignorant about these things, but at this time things like messaging (IMO), mapping, and some of the other default features are of no use to me. They seem to be eating up a lot of resources. I can kill some of the services I think they are associated with, but they keep popping back up.
I did watch the "noob" video (color me a tiny ant to be squashed) and did try to search for an answer to get me even started. I've read the huge main A2107A thread (80+ pages) and tried three of the suggested ADB drivers with my Vista 32 setup for my A2107A-F. The only one that even seemed to connect was ADPnet and it showed the tablet as a Android Phone. Maybe I'm just too paranoid, but after the multiple "brick" posts I'd like to make sure I'm on the right path before trying to "root" the device which appears to be the first step in removing all the extra stuff Lenovo added.
Not that it matters, but I've had the tablet for almost two weeks now and my favorite things are Slacker Radio, Scrabble, Roll It and Zen pinball. I do play Words with Friends with my wife, but I don't like it since some of the words they allow are not valid in Scrabble (which I used to play as an expert competitively face-to-face).
If you are so inclined, feel free to PM me for a Scrabble game. I promise I will not use anything other than my brain and the built in dictionary to make my plays. (I'm a bit rusty since I gave up competitive Scrabble in 2006).
So, long story short... Thanks in advance for any and all advice you can give on slimming down the Lenovo A2107A-F. And if you want an honest Scrabble challenge feel free to PM me.

As far as checking if your drivers are installed properly I would open a dos (command) prompt in window and from within the window change to the directory where you have the 4.03root files. From the command prompt type 'abd.exe shell' and you should see something like "[email protected]:/ $". If you don't see this then you will not be able to root! You need to make that USB debugging is turned on on your device you have an entry in the device manager for ADB Interface (expand on the device which you have showing up).
I am no expert, and I struggled with this on my first go also
Once rooted you can then install Titanium Backup from the play store and use it to get rid of the bloatware! Proceed with caution however as it is possible to remove critical system apps!

Thanks! That's the type of test suggestion I was looking for to make sure I was on the right path with the driver.

So has anyone tried creating a rom for this tab yet? I've been doing some research into porting another rom to work on the A2107A-F, but want to make sure there isn't one already.

I just received a notification of a new firmware update for the A2107A-F. This would be the second available update.
Has anyone else gotten this and taken the plunge yet? I'm curious if this is possibly Jellybean, as some of the larger screen IdeaTab models run this.

I lost root after applying the first update a while back. That's typical when updating. Afterward, I was able to re-root mine again using the same procedure as before. All was well. So, don't panic...yet.
Can you report on what other changes the update made? Is it Jellybean? Or maybe ICS 4.04?

Although I have my A2107A rooted and tweaked to my satisfaction, there are a few lingering issues that I'd hoped an update would correct:
1) The neutered Bluetooth stack. The tablet is supposed to work with Bluetooth keyboards, mice, etc. It doesn't. Although I've gotten it to talk to an external GPS module, other Bluetooth data connections simply will not work. Oh, and Bluetooth audio? Forget about it!
2) Some settings that are present in stock ICS builds are just omitted in this one. As an example, the ability to specify a default TTS voice. It's present under settings in my wife's tablet and every other ICS build I've ever encountered. Not this one!

I was rooted too, lost root access (only with some apps!) after the 130221 update Feb 28. I'll try the same root procedure as before to see if I can get it back. Glad to see a thread on the popular US version A2107A-F. Maybe someone will port Jelly Bean to this tablet! Doesn't appear Lenovo wants to do it...

I cannot get this 'update' to install after downloading. The tablet reboots to CWM during the install (I am rooted with CWM installed) and when I attempt to manually select the update.zip from /sdcard/googleota/ I get on error (status 7). In desperation I re-loaded the stock rom that I found on another thread and when the tablet attempts to update I get a "assert failed apply_patch_check( /system/app/applicationsprovider.apk)" error Anybody any ideas?

I'm in exactly the same boat as you. I'm getting the same exact error. except that I do not have CWM installed (I am rooted though). Perhaps there's a problem with the update.zip?
Something odd that I noticed however: After the tablet reboots into recovery mode, the update fails, and I go to browse for the update.zip, the sdcard/googleota directory is missing (along with everything that follows it alphabetically). They reappear upon normal boot. I've tried copying it to a directory closer to the beginning of the alphabet and it does show up while in recovery mode. But it still will not install.
Maybe I somehow do not have the available space to perform the update? Is that possible? I show plenty of available space on both sdcards. Could we somehow be below a certain ROM space threshold necessary for an update?

I think in my case because I loaded a 'stock' rom I got from another thread, this rom is failing a verification test the update is doing before install. I do not know how to get around this! I'm continuing my search, but I am not so confident this will be resolved easily...

Well, I am running a stock rom. I am unwilling to "mess with success" until there's a 100% reproducible way of recovering if it fails. And, so far, everything I've read in the other A2107A thread has been hit or miss for the A2107A-F people.
Anyway, If the update is performing a verification test, then it my "virgin stock ROM" should certainly pass it. The only thing that I did is to root it. Hmmm...could the update be testing for that and refusing to install if it detects a rooted device? I would tend to doubt that, since the previous ota update went just fine. I lost root in the process but easily reapplied it afterward.
Thoughts?

Interestingly, I flashed the A2107A-F_S483_121115 rom (again, found in another thread) as I was having verification problems with the OTA update just released from lenovo which was available from the A2107A-F_S484_121211 flashed rom. While the S483_121115 rom appears to be older, I no longer get the option to update via OTA as the tablet is telling me that my s/w is up to date! Go figure.

It's really too bad this device hasn't taken off. If I actually knew how to dev then I would start developng ROMs for it. I'm enjoying it now that I have root and got rid of bloat.

Hey guys. Just wanted to say if someone can send me a stock rom and be willing to test, I'll try to do up a good rom for the -f models. I'd use mine for the stock rom, but I've edited a lot of the system, so no go there. If you have the stock rom or want to be a tester, let me know.

The officially unofficial Tiamat Moray ROM Q&A Thread

This thread is an attempt to help out the Tiamat Developers by answering the frequently asked questions in one consolidated thread. This thread should also be helpful to those who either cannot use the search feature or are having a hard time figuring out the correct search terms to find what they are looking for. If you have suggestions or added questions/answers feel free to reply and I will update the OP.
NOTE: I am not a developer. All of the information in this thread is from other members who have helped me out or information I found in the XDA forums. I do not take credit for any of the great work that has been done on this ROM and I will point back to the original answer when possible. I am only trying to help lessen the burden on the developers so they can spend more time getting us the best features. Hopefully you find this helpful as well.
I've flashed this ROM and now I get update notifications. Should I accept the update? How do I stop these notifications?
No, you should never accept an OTA upgrade when using any custom ROM/Kernel. This could result in severe problems. Your best bet is to be patient and give the developers time to react. If the update is worthwhile I am sure they will roll it out pretty quickly.
To get rid of the notifications flash Mod pack 3 as noted here.
OK I made the mistake of accepting the OTA update and now my Xoom won't boot. What can I do?
okantomi said:
Can you make it reboot by pressing volume up and power at the same time and holding? If it reboots, wait about 3 seconds once you see the dual core logo and then tap volume down you shoud see android recovery, then tap up to choose it. I hope you did a nandroid backup. If not, you can try and get fastboot by tapping volume down sooner after it reboots.

From this thread.
With this ROM certain websites don't load correctly or I can't get to the mobile version of a site.
This ROM by default sets the User Agent String to "desktop". If you want to revert to the stock settings flash either Mod pack 1 or 2 depending which version of Moray you are running. Look here.
I flashed this ROM and now when I click links in email or my file explorer the screen just dims and nothing happens.
This is a bug in Android 3.2 and not specific to this ROM. To solve this, simply ensure auto-rotate is enabled and rotate the device from landscape to portrait and back to landscape. The app chooser window should appear allowing you to choose which app to open the selected file.
I just flashed this ROM and the speed is amazing, so I OC'd it to 1.7GHz cuz I want more and I am now stuck in a boot loop. This worked for others why not me?
The Xoom was only specified to run at 1.0 GHz, anything beyond that is a gift. Due to part-to-part variation not everyone's Xoom will be stable at the same speed. Yes some people are able to run at 1.7 GHz, but many cannot. For your specific Xoom try out the various speeds, but do NOT click "Set on Boot". This way if it crashes it will revert back to stock speed and you will be able to boot. Once you are satisfied with a speed then feel free to enable "Set on Boot". Before you do so I would suggest making a nandroid backup so you can restore just in case.
How do you get out of this boot-loop? The only way I know of is to boot into recovery and restore a nandroid backup if you have one or perform a full wipe if you do not.
I updated to the latest CWM and I cannot find the zip card or I get "get error: E:failed to mount /sdcard (No such file or directory)."
Latest is not always the best, for the Xoom you need to either use ClockworkMod 3.2.0.0 (R4C) or CMW Rogue Recovery v1.1.1
After flashing this ROM the Motorola icon gets distorted during boot up, is that a problem?
Basically it is not a problem. This kernel has a patch provided by NVidia which causes the distortion during boot. It does not cause any problems after it boots.
Is there a way to get the stock WiFi and Battery icons?
Yes
How do I boot into recovery without ADB or my PC attached?
There are a couple methods.
1) The latest Tiamat ROM includes this if you press and hold the power button. Just pick what you want and hit OK.
2) Download and install "Quick Boot" from the market. It gives you the above options as well as others when you run the app.
3) Turn the Xoom on, wait ~2 seconds after your see the Dual Core logo, then press the volume down key. In the upper left corner it should say "Android Recovery", then press the volume up key to select it.
How do I get started? Any good guides?
There are several guides that are pretty good. The best one I have found and personally used is here.
The Xoom Heaven thread found here is also a good place to start for all sorts of information.
If you have another question please feel free to post to this thread. If you are having a problem or have a question it is likely that someone else along the lines will have the same problem or question. I will continue to update this OP with the list of F.A.Q.s.
Additional Q&As
After installing this ROM I am having issues with the market not finding all of my apps or apps are giving errors when trying to install them.
See this post for one possible solution.
One more for good measure...
HuckFinn, I think you have covered most of the hot issues. Great job!
Stickied. Thanks for posting this, and Solarnz for giving me the heads up to do so.

It's what you pull your hair out by when something is not working properly!!
darn you... I earned 1/2 my posts responding to the "why does my screen dim" question... now I'll have nothing to say!
i performed a factory reset from the os-> settings and once again performed a wipe/factory reset from the cwm recovery but still can't get back to the initial setup screen (where you enter your google a/c, etc)
any idea?
Thanks!!
Here is one..
Why does Market show up in USD even though my locale is set to UK, my language is English British along with my keyboard layout?
Ive had boot loops twice. Both times i could get into recovery but could not get backup to restore . kept getting cant read /sdcard. also cant reinstall update .zip becuase the sd card wont mount. I have only gotten back in by letting it sit powered off for a bit.
any ideas?
should i adb a stock image and start again?
should i flash a different recovery?

What version of recovery is installed now? If you have the version that doesn't recognize your external sdcard you should certainly flash a compatible recovery version through fastboot.

Guess I should have read the thread before posting here, sorry for being a troll.
I tried this ROM on my 4G Xoom, but it left me without 4G or 3G (wifi only). Any way to get this working, or do I have to wait for an update?
I did try activating the network in settings, but it never connected even half an hour.
Thanks to steps mentioned by user 'LordDeath' in another thread and a bit of experimenting with a rooted 4G Xoom and a friends 3G Xoom running Moray, there seems to be a remedy for those who are having issues with the market compatibility issues as well as missing apps. I did not activate until attempting to sign in to the market and had missing apps and compatibility issues. I simply did a full wipe & reset and made sure the full activation went through in set up then let it automatically start restoring. I took a peek in the market after a a minute and all my apps were back with no compatibility issues. Here is a copy of his original post and mine but the last step was not needed for me.

Translated into English it means "Error while processing the purchase". It was a free app, btw.
To solve this issue I did the following:
1. Wipe data/factory reset
2. Active the device during the wizard on the first boot with my Google account
3. Restore the nandroid backup of the official 3.1 ROM
Therefore it seems that the market servers check your device-compatibility only during the activation process at the first startup.

"This fixed everything for my friend running Moray and even corrected the issues on my 4G Xoom..."
I should add that though this fixes the issue, if you change your pixel density you may run into similar issues but can correct it by setting it back to 160 before going into the market.

[DEV & CWM Recovery for Pantech Crossover]

Forgive me if I'm posting in the wrong section. Forgive me if I'm not allowed to post here yet. Just forgive me in general. I don't want to be banned or anything like that. I'm Extremely interested in android development.
I made a working port of ClockworkMod Recovery v5.0.2.8 for the Pantech Crossover. I wanted to do this before I started tinkering around with porting cm7.2. So that I would have a way to backup, restore, and flash new roms, etc... Or else when I make a noob mistake like yesterday and have a non booting phone resulting in having to flash my old boot.img with fastboot...anyways..
DANGER: DRAGONS AHEAD
FLASH AT YOUR OWN RISK
YOU HAVE BEEN WARNED
The method I used to flash the recovery was:
1)adb push recovery.img /sdcard/recovery.img
2)flash_image recovery /sdcard/recovery.img
3)repeat step 2 (for some reason it gave me a read error out of memory the first time)
Here's the link to the custom recovery:
http :// dl. dropbox .com /u/20070520/ recovery.img
I know I'm not supposed to post links yet. Remove spaces
I just hope that there are others with the Pantech Crossover that are interested in this and the possible future development of custom roms.
Also if anyone knows if there is a good way to get ahold of koush let me know, so I can give him what he needs to hopefully add this to Rom Manager. I couldn't message him on github because he doesn't have an email set up with it
And while I'm at it. Here's the method for rooting your crossover. I'm not going to provide the files since they can easily be found with a google search.
1: Find a copy of gingerbreak.apk and copy it to your sd card
2: Enable usb debugging and allow installation of non market apps
3: Install gingerbreak
4: Root device with Gingerbreak
5: You can uninstall Gingerbreak when its completed.

Thanks so much for this! I have a friend with a crossover and is always looking for my help with making it work better. I realize this is a newer thread, I was wondering how things were coming along with CM? Anything I can do to help perhaps?
crap i need a rom to fix my crossover the buttons are no longer mapped after a hard reset. please help.
Slow
Well, it's been slow goings so far. I downloaded the open source files for the p8000 and it looks like they just built the original rom from a generic build. I've been trying to get a more customized build setup but I need to do some more reading so far. One of the problems is that instead of an akmd(2) binary for orientation and compass it uses three separate modules. Plus the hci_attach is a bit different as well and so is the bluetooth. So that significantly hampers the ease of even a basic port.
As far as the gentleman with the question about a rom to fix your device. The best I can do right now is to upload a clockwork mod backup after I do a factory reset. I don't get much time to work on this between my wife and daughter.
Also, do you have adb access to your device? Surely it wouldn't be too difficult to adb push the correct keymapping files back to your phone.
You say a hard reset messed up your mappings? What problems were you experiencing prior to the reset?
Crossover
Hello,
I just wanted to let you know that there are people watching your thread. I am very interested in this as my parents have Crossovers and have recently rooted and unlocked them (well, I did) and set them up to work on Net10.
The only issue I've noted is that there are some failures, like the Market refusing to install apps no matter what is done. I'm going to install your ClockworkMod in hopes that later it might be useful.
I realize there isn't a large development scene for the P8k yet, and maybe there won't be but it's always a great hope that those with the capabilities might take pity. I was almost thinking that it might be my foray into actually looking deeper at the code than the small bit I've done.
Kind Regards,
Kaylus

I haven't had any problems with the market refusing to install apps but I do sometimes run across the no connection error with the market when on wifi. Although I did notice this before I rooted my crossover. Sometimes disabling and re-enabling the wifi helps. I really do think it is a bug somewhere in the original rom.
As far as the custom recovery image. Everything seems to be working pretty good. I use it mainly for restoring previous backups. I would say I've restored my backup at least a dozen times. Occasionally it states there was an error restoring .android secure but I have yet to track that down. I need to double check the recovery.fstab to make sure I have everything set right for the mount points.

I'm actually completely stuck at this point. I'm rooted, unlocked, different carrier, APN set correctly. I can access data and voice -- but it just hangs at "Downloading..." on the market. If I factory reset it works initially but after reboot it fails. I'm not quite sure why this occurs and if it is just this phone or a side-effect of using it on a different carrier.
Strangely Wi-fi doesn't resolve it.

I'll give your recovery a run and let you know, if you manage CM7 let me know I know it's a big undertaking. Thanks for the response.
Market Error
As far as the Android Market hanging. I see a few references to it being cause by the .android_secure folder becoming corrupted on the sd card.
One temporary fix suggest moving all the installed apk's back to the phone memory and deleting the .android_secure folder. Then rebooting and moving those apps back to the sd card.
That seems like some wasted time if it doesn't happen to work. I would just turn the phone off, remove the sdcard, and restart (granted any apps that were moved to the sdcard wont work until it is reinserted.) Then I would try to download and install an app. If that works then shutdown, insert sd, and reboot.
I'm really curious if the problems with .android_secure that you and i are having aren't just more bugs in the original rom.
Just as a poster above me said, I am watching this thread and really appreciate everything you are doing. Thanks again.
Well I appreciate the support. I just hope to be able to offer a rom sometime soon. Unfortunately I won't have anymore free time till Tuesday

Pantech Crossover Update
Ahhhhh check out the pantech support page for the crossover. They finally have the Gingerbread update.

Which is great because I soft bricked my phone (don't ask) and this was going to be the only way to fix it.

Mildly related, but have you figured out how to root the gingerbread ROM? I've tried ginger break to no avail.

anyone have a stock image of the 2.2 for android my phone came preupgraded to 2.3.6 and i would like to have it rooted over being on gingerbread since a root method hasnt been found yet for the new firmware
Bricked?
I tried to use the pantech provided gingerbread update this morning. It got about an eighth of the way through and failed. It instructed me to reboot while holding volume up and home and power. That put it in software updating mode. I tried the upgrade 3 more times, it failed at the same point each time. Now my phone is stuck in S/W Updating mode and I can't seem to get it out. I've tried pressing volume up and down for 10 seconds, and pressing volume down and home while powering on, nothing seems to make a difference. Any thoughts about how to at least get me back to froyo?

[Q] My Asus TF300T is on stock Android 4.0.3, what to do next?

The darn thing just started nagging me with an update notice that comes back every ten minutes. I read somewhere that updating is going to stop me from doing certain advanced things, so I finally got the last push to go for either CM10 or CleanRom, depending on which one gives me the most advanced and pleasant experience.
But before doing so, it's recommended to get some kind of flash info file or something from it that doesn't come out when upgraded to the latest firmware but does on the old 4.0.3. What would be the best way to go from now on?

Your tablet will say it is unlocked in the upper left part of the screen when The Asus logo appears at boot.

Hi, if your tablet is still on stock 4.0.3 (ICS bootloader), I recommend doing NVflash first
http://forum.xda-developers.com/showthread.php?t=1894867
If you have already updated to JB bootloader it won't work.
It doesn't say Unlocked, so I guess that's why I don't see the USB option when I try to get into Fastboot?
I'm also not able to get ADB commands recognized on my win7x64... Am I doing it wrong? What's the proper method/order of events here? Isn't there a really n00b-proof version of a guide here, or is it something I should write as soon as I get out of this mess and get it working?

Perhaps I'm not really looking in the right location, but the Asus website says I need to choose an operating system and gives me no option to choose. This way I'm not able to download the apk...
Edit:
Tried clicking the links with the tab and it started the download... Device now has an unlocked bootloader. On to the next one...
Edit2:
Ah, now I get it. Pay attention to where that Android SDK stuff is being installed. Mine got installed in the folder I unpacked the installation files! So somewhere 256 folders deep on the Desktop was the right 'adb.exe' file. Make sure the tf300_nvflashpack files are in the same directory and open the command prompt there. After that I got back to the http://androidroot.mobi/t3_nvflash/ website and entered the commands. One moment please, back in a flash!
Edit3:
Now I have 5 files in /mnt/sdcard/AndroidRoot and I uploaded them to my Dropbox. I'm guessing they are the right files...
blob.bin
blob.log
bootloader.ebt
create.bct
recovery.bct
To be sure I uploaded them all.
Copied these files into the SDK folder, along with the other zipped files for nvflash so the nvflash command works to get the other three backup files.
Edit4:
Went on following the guide and checked the video to see if I was really going the right way. Finally I have all files backed up. Goddamn what a journey, but it makes you grow a pair of balls. Now on to the next hurdle, getting a proper ROM, because stock is really getting on my nerves.
So CleanRom, CM10 or Energy ROM? Should I first upgrade to JB? Without or with the popup I'm constantly getting?
Lex,
You have alot of the same questions I do/did, and I have your original post open in another window to respond to all your questions. I'm working on writing a guide for all this stuff so this is rather helpful. If I respond to a question twice, please forgive me as I'm literally just going down the list and answering em as I read em.
In your first post, the file you're referring to is gathered via NVFlash. I haven't used NVFlash yet, but what I understand is that if you use this tool it basically backs up your ICS (4.0.3) bootloader information. The newest firmware change is to Android Jelly Bean (4.1.1) and that re-locks your bootloader. Once you go to JB, you cannot go back. So this servers as a backup (again, this is just how I interpret the information from their website. I don't know how correct my interpretations are, and have actually opened a thread to ask for clarification about this program).
For the drivers, all I did was download the android SDK and install the 'android tools' and "extra - google drivers' from the list. My laptop was just recently wiped-out so I have no prior drivers installed, nor have I connected my tablet to my computer yet (just got a replacement tablet last weekend). I didn't use the universal driver or any other add-ons. Just use the SDK, it will install drivers, and then it will detect your device. I verified this by typing "adb devices" in command prompt and it detected the serial # of my device.
Within that same post, you had some confusion about ADB. It's just an executable, and you have to use the command prompt window from whichever directory it is installed to. So once you unzip the Android SDK or wherever you installed ADB to, use the command line commands "cd directory/where/adb/is/installed" to navigate to it, or use shift + right click within that folder and it will have an option to "open command prompt here" with admin privileges. That makes life a bit easier. Other people also install their SDK to C:\android\SDK or something similar, so it's less to type.
In order to determine if your bootloader is unlocked, look at your tablet in the top left hand corner when it boots up. It will say "Device is unlocked" and list a bunch of numbers (which if I remember correctly would just be the firmware information). Your device will not be unlocked until you actually download the unlock tool from asus' website and push the file via adb to your tablet and install it. That is, you have to take a very specific, very advanced overt action to unlock it. Nothing else and no one else can do it for you nor can it be done accidentally.
Next post (#8 in the thread): You are correct that fastboot will not show unless you are unlocked. I just verified this on my not-unlocked, not-rooted new tablet, and cannot enter fastboot mode. Your ADB commands wont work if your drivers are not correctly installed.
Post #10: You have to select "Android" under the OS drop-down box to find the unlocker app. As for the location of the ADB.exe, mine was found in this subfolder within the android SDK: <whereveryouunzippedit>\Android SDK x86_64\adt-bundle-windows-x86_64\sdk\platform-tools
That folder contained the correct (and I think only) adb.exe I needed.
For your last part, I think you should try out a number of ROM's to see which you like best. I've tried all the major ones (CM9, CM10, CleanRom, Hydro, Blackbean, and some of the stock rooted/de-odexed) ROMs and used Blackbean for the longest time because of how slick it looks (all black) and how easy it is on my eyes.
Make sure you document the steps you took so you can remember them in the future. I'm working on writing a guide right now and documenting my steps to go from a stock, locked, and not-rooted tablet to a rooted unlocked and custom flash tablet.
I really hope I was able to clarify some things. I am by NO MEANS an expert but I've spent many hours experimenting and think that I wish I had someone to answer my questions when I was first learning, rather than learning by mistake.
Hopefully this helps,

Hi, I use Energy rom which I find pretty good, you will need to update to JB first as Energy, CM10 & Clean rom are all JB bootloader compliant. My tab came with JB pre installed so not sure what the best way to update is but would assume since you still have stock recovery would be with OTA update (popup notice). Here is a guide to update to JB but I think this is if you have already installed a custom recovery as it looks like you flash back to stock recovery first, thats why I think if your getting update notice and still have stock recovery, go with that.
http://forum.xda-developers.com/showthread.php?t=1845377
Once you have updated to JB stock here is a guide to install custom recovery (CWM or TWRP), root & install custom roms.

Same goes for you! Tomorrow I will be trying as much ROMS as I can to see which one suits me best. Also repeating this process is the best way to learn something and since I'm unbrickable, I am going to flash the hell out of it for a few days. I'll try to post my steps and findings here so I (and perhaps others with the same trouble) can benefit from it in the future.
Also I think when you update to JB your bootloader will be locked again (new bootloader), the above guide on root, customs roms also has info and links on unlocking JB bootloader. Glad I could help, have fun :good:

It's upgrading now. Of course I forgot I lost root with the last OTA update and I forgot to make sure I rooted the thing so it was able to use the rootkeeper after upgrading to JB. I hope there is some documentation on rooting JB, because at the time this all happened root was not possible yet. It's past 1 AM over here, so I guess it's best to save this quest for later when I had some sleep.
Edit:
Just for kicks I tried 'Root Checker' and it said 'no root'. Then I saw 'Rootkeeper' was installed. Opened it up, tapped the restore button... Device rooted! Guess my memory is really failing big time... One down, # to go.
Edit2:
Installed TWRP:
Just downloaded the .blob from their website and
put it in the platform-tools folder.
Then renamed it to TWRP.blob.
Turned off tablet,
plugged in USB cable in the tablet ONLY,
hold volumeDown button,
plug into laptop holding button,
waiting...
choose USB logo,
open cmd-line in the platform-tools folder,
run command: "fastboot -i 0x0B05 flash recovery twrp.blob"
waiting...
Done. Let's see if it works...
Edit3:
At first I didn't understand how to get into TWRP (DOH!),
Hold volDown, power on, choose RCK.
Edit4:
Been having a fight with TWRP when I try to install CM10.1 (latest nightly: 20130121). Gives me an error status 7 or something...
Code:
Verifying update package...
assert failed: getprop("ro.product.device") == "tf300t" ||
getprop("ro.build.product") == "tf300t"
E:Error in /external_sdcard/CROMS/****.zip
(Status 7)
Error flashing zip ' /external_sdcard/CROMS/****.zip'
Of course, ****.zip is a long filename I didn't want to type completely here.
Will try to figure out whats wrong later today, first I'm going to try restoring the backup I made earlier, just to see how a complete backup works when the tablet is wiped back to factory settings.
Edit5:
The backup stuff is really cool! My tablet is back the way it was even though I wiped it completely!
Back to the ROM rumble... baked_tf300t_blackbean-6_jb-bl_b6.zip gives me the same error. Starting to get annoyed again... Let's try something different, CleanROM. Download is taking ages... I'm restoring again, so I can use the tablet for the rest of the day. As soon as I feel like it I will try again, for now I'm giving it 'the finger'.
Edit6:
Cleanrom is installing now. I guess CM (baked is CM based right?) was causing some trouble...
Done installing...
Wipe Cache/Dalvik...
Reboot...
Android is upgrading...
Might need to choose the small font, my screen is really clogged up with stuff. Didn't expect to keep my settings etc., thought it would be completely wiped. I'm going to restore and then reinstall with the highest DPI setting first, then I'll wander around the rom to check if I like it.
Edit7:
I think I'll stick with this one for a few days, runs fine if you ask me, maybe take the time to finally update my Galaxy Nexus to CM...

Easy guide to twrp and 2nd bootloader

Hello all!
Do you want TWRP, a 2nd bootloader, and custom roms at your fingertips for your Kindle Fire HD? Well you have come to the right place! Over the past months, through trial and error, I've managed a full-proof, easy method to unlock the Kindle Fire HD's true potential. While this is aimed at 7" devices, it should work no problem on the 8.9 either - however you will have to use your head. These instructions are geared towards the 7", and you will have to realize what changes to this blueprint you personally will need to make with the 8.9.
!WARNING! WHILE THIS HAS WORKED FOR ME ON MULTIPLE DEVICES, YOU MUST FOLLOW THE DIRECTIONS CAREFULLY. I PERSONALLY SUGGEST YOU FIRST BUY A SkOrPn FACTORY CABLE IN CASE ANYTHING GOES WRONG. (Although using this guide, it almost certainly will not. Still, those cables come in handy!! :good: ​
Also, I would like to point everyone to seokhun's thread on this matter, which came before my own: http://forum.xda-developers.com/showthread.php?t=2271909
BIG thanks to LinearEquation for helping maintain this thread. Trust any advice he gives; it WILL help! :thumbup:
Although our posts on this process are essentially similar, he goes far more in depth on the process, and has an excellent troubleshooting section if something here goes wrong for you and I cannot respond to your question soon enough (although if done right, that won't happen )
Ok. Lets begin!
Step One: Download Kindle Fire First Aide, an amazing tool which is only getting better: http://forum.xda-developers.com/showthread.php?t=2096888
This is probably the most work-intensive step, although once you have it you'll be glad you do. You are to follow the directions on this thread and install the necessary files, and adb drivers. This is necessary for your KFHD7 to communicate with your computer properly. When finished, make sure your Kindle has ADB enabled under its device settings.
lets see if you're ready for step 2. Plug your kindle in and check your device manager. If your kindle fire shows up as "android adb interface" then you sir/ madam are ready. If not, please use the Kindle Fire First Aide (hereafter referred to as KFFA) thread to find out where you went wrong. The answer you seek will be there, I promise you.
Step Two: BACK UP ANY FILES/FOLDERS/MOVIES/ETC YOU WANT TO KEEP. STEP THREE WILL WIPE YOUR DEVICE!
Step Three: Here, we are going to use KFFA to reset our device to 7.2.3. Make sure you have transferred any backups you have made to your computer. Run KFFA and select the option that reads "Reboot the Kindle into Fastboot Mode". At the time of this posting, there are two options to do this. Try the preferred option first, and if that doesn't work, try the alternative method. Alternatively, just plug your kindle in with a fastboot/factory cable to get it into fastboot. YOUR DEVICE MUST BE IN FASTBOOT MODE FOR THE NEXT STEP
Step Four: while in fastboot mode, in KFFA, use the option "COMPLETELY RESTORE THE KFHD7 7.2.3. This will take a while, and you will be prompted at certain points to continue. I usually chose not to wipe user data at the end, as for me at least it takes forever and shouldn't be necessary.
Step Five: While still in KFFA, Disable Amazon's OTA updates with the option provided. This is important - If an update sneaks by, you will have to start from scratch!
Once KFFA says it's finished, unplug your device and hold the power button to hard-reset it. Now boot it back on. Your kindle will now be stock 7.2.3, with google play and superuser installed, along with root permissions.
Step Six: Here we go! Download the provided FireFlash11.apk, kfhd7-Freedom-boot-7.3.0.img, and kfhd7-twrp 2.4.4.0-recovery.img to your computer. Connect your KFHD7, make sure you check "allow installations of unknown applications" on your kindle's options (they will have reset thanks to KFFA, don't forget), and go to either the amazon or google play marketplace and find a file browser you can use to navigate to your download folder. Find where you placed the FireFlash11.apk, open it, and install.
Step Seven: Almost there guys! Open up your new FireFlash app. The first thing you (should) notice is that there is a warning that you have the incorrect bootloader at this moment. Check the box that says "Flash kfhd7-u-boot-prod-7.2.3.bin. scroll to the bottom of the app, where it says "execute", and press "flash, install script". Exit the program and reboot your device.
Step Eight: Now that your kindle has rebooted, open up the FireFlash app again. This time, you should see no warnings at the bootloader. If for some reason you do, STOP and retrace your steps. If you see no warnings, we're ready to install the 2nd bootloader and TWRP!! While still in FireFlash, under "boot partition" it should say "not flashed". Click on the "not flashed", and navigate to the "kfhd7-Freedom-boot-7.3.0.img" that we downloaded earlier. Check the box next to "apply stack override".
Now, under "recovery partition", again select the "not flashed" box and navigate this time to the "kfhd7-twrp 2.4.4.0-recovery.img". Once in place, check the "disable recovery auto update" box to the right. Now scroll to the bottom, to where it says "execute", and tap "Flash, install script" just like we did before with the bootloader.
Thats it! Select "reboot into recovery" from the Fireflash app if you're still in it, and if you followed the instructions and put everything where it belongs, you should wind up in TWRP after your kindle reboot (dont worry if you see the blue kindle fire logo for a minute before it enters TWRP - it's completely normal. From here you can install custom roms, wipe your cache, and most importantly MAKE BACKUPS! :laugh:
ATM I am using Hashcode's CM10.1 with the 1.5 ghz kernal, with Nova Launcher Prime and LMT launcher. It's simply amazing the difference in both speed and functionality. Hopefully, this guide got you there and now you too can enjoy a fully unlocked Amazon Kindle Fire HD!
Here is a link to the page for Hashcode's CM10.1, If you want to give it a shot I highly recommend it!! http://forum.xda-developers.com/showthread.php?t=2245335
One last note. I want to make it clear that I have not personally developed any of these tools, I've just organized them for you. The real ones you want to be thanking if this works are the developers. Thanks Devs!! :good:

I wrote this tutorial as a newer method of achieving TWRP/2nd bootloader, as every OTA update amazon pushes out makes different root methods temporarily break/ ineffective, while this method SHOULD always remain consistent with the help of KFFA doing the rooting. However upon going back and looking over your thread again, I now realize there are quite a few similarities. I strived to simplify mine as much as possible, which is why I avoided the troubleshooting section and left explanations of the process to a minimum. As your guide is more in depth, I will edit my original post to include a link to yours as well should people want additional information/help. Please, don't look at this guide as an attempt to derail yours - rather as an attempt to simplify it even more. I apologize for not mentioning your thread in my original, that was an unfortunate oversight, and thank you for bringing it to my attention :good:

Had a look at your guide and thought why not...checked with Chris of KFFA about rooting KFHD 7 with 7.4.3 update, he gave me the 'fakebackup' file. Rooted with KFFA....followed EXACTLY from your step 6 to 8 and ATM doing a TWRP backup.
Fantastic job mate.
One question though. If I am going to put another ROM to KFHD7, do I need to do a full wipe (cache, factory, delvik) everytime before a flash install?

I'm delighted to hear that my guide helped you! And sorry for not getting back to you sooner. Seokhun seems to have managed to point you in the right direction, but in case anyone else needs an answer (or of course, you still do ) you only need to fully wipe when going from one type of Rom to another (ie: from stock Amazon to cyanogenmod). This is known as a "clean flash". Otherwise, if say you are simply upgrading cyanogenmod or whatever Rom you're on to a new update, all you really need to do is a "dirty flash" - wipe delvik/cache and you're good to go!
More info on this can be found here http://forum.xda-developers.com/showthread.php?t=1882629
Cheers!

I decided to try this again.
I rooted the tablet and used Fireflash to re-load 2ndbootloader using the 7.4.3 series of Hashcode files.
Once I was not able to boot up into the 7.4.6 OS because the 7.4.3 boot image is used for 2nd bootloader as I expected.
I had downloaded, the 7.4.3.zip stock OS to the sdcard originally so, it was still present locally.
I flashed the OS zip and I was back to 7.4.3.
I downloaded 7.4.6 again to the tablet and again was presented with the Bright update Kindle in "More+/Device/About".
After, the update, I was again without 2nd boot and unrooted.
Point though is the update should not occur if the zip OS was in fact blocking OTA updates.
Is the zip file supposed to have OTA blocked?
I used KFFA to block updates as a second test and once disabled with KFFA, the update is Grayed out and then once re-enabled with KFFA, the update is bright and does update.
I know a lot of people have complained about OTA happening even when blocked...
It looks like this Zip is not blocking.
I will try the LINUX rootplus to see if it blocks OTA...

Well if you said that KFFA works, then why not keep that?

Yes: Of course, you would keep what works and in this case, KFFA works.
However a ton of people have used various other methods over the last year or two and KFFA is pretty new.
Lots of people have written in saying "why did I get an update when I am blocked?"
I was just offering a reason why.
You can find lots of pre-rooted ROMs on the forum that all say "Rooted, No ADs, and OTA blocked, Gapps, etc.".
The user takes that descriptor on faith and flashes the ROM thinking they have what they need.
In my case, I purposefully updated to 7.4.6 and needed a way to get back to an older version of Kindle OS.
I restored back to 7.3.0 then flashed Hashcode's, 7.4.3 ZIP OS.
It was there I realized I could then update to 7.4.6 which I should not have been able to do.
Just a point of information.
Another point or question is whether there is a difference between a true OTA update that takes place automatically and the case where the user downloads the update to the tablet and then selects "Update" in Device/about. I have always thought it might be nice to have an option where the OTA is blocked but, the user could still download and update manually. When the KFFA method is used to block OTA, both options are blocked.

If you're trying to get a custom Rom, this thread is for you. If you wanted the newest Amazon update with working root, wrong thread
From the first step to the last, my guide can get you twrp and root and a set up for a new rom. No more, no less

I don't think Hashcode removed the OTA Scripts. He may have, but I'm not sure.

This thread is a continuation of some of the discussion that was from this thread: http://forum.xda-developers.com/showthread.php?t=2568427
While not at all high end tablets, it's always fun to see what can be squeezed out of them! As stated in the title, this thread will be regarding the following devices: Nobis NB07, Iview 774TPC, and DA-741QHD (which all appear to be the same hardware) rooting and ROMs. That should be pretty simple for now since, we currently have no ROMs and no proven root method. Some have reported success using the Kingoapp. If anyone is able to obtain root, we would like to ask that you make a copy of the firmware and upload it for those of us having trouble doing so. After doing so, we can modify it and hopefully get more our of the software.
You may also post information regarding tweaking the ROMs for these devices and other ways to make them more useful!
Warning: The following may have unforseen effects including breaking your tablet to the point of being unrepairable.
Option #1, Use KingoApp Some users have reported that this did not work for them, at least one user reported that it did.
Instructions per RawX:
For the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers. That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times. I've done this were for clients of mine but its pretty straight forward.

The working drivers for me were: VID_1f3a_PID_efe8
Please consider trying this first and give us some feedback. A word of warning though, there has been some discussion on XDA in the past that this may be malware though I'm not sure this was ever confirmed.
Option #2, Flash firmware for an alternate device that can be rooted easily. Warning!!! Currently, there is no way to get back to stock (until someone who gets root with another method makes a copy of the firmware)
Go to this website: http://www.iviewus.com/firmware788TPC/ and download the firmware. Yes, it is for another tablet. However, the tablet appears to have the same specs as ours. Once downloaded. Install the included PhoenixSuit software. Once it is running, click the button at the bottom right to update the software to the newest version (this may not be required). Then, plug in your tablet using the usb port and install the drivers. I used google and found them all within minutes. Once the software recognizes your tablet go to the firmware tab where you have extracted the .img file and select the file. Next, click upgrade to upgrade your tablet (it has instructions to help your tablet be recognized if you are having difficulty). Once the new firmware has been flashed, then download the file RootFromOTA.zip that can be found on various places such as XDA. Move the file onto an external SD card. Then, go to settings -> backup & reset -> Recovery Mode. Your tablet will restart. Once it does, select the bottom option to install from SD card. Install the RootFromOTA.zip and then reboot. Once rebooted, install the supersu app or another root application of your choice.

Congrats... You're rooted.
Mods
Currently, I've managed to get great battery life out of my tablet by installing kernel tuner and changing the settings as such:
Governor: Ondemand (default is fantasys)
Max: 1200 MHz (Default is 1200 MHz)
Min: 240 MHz (Default is 120 MHz, but I had trouble with usability at this setting and Ondemand)
I also recommend setting wifi to turn off when the screen is off and turn off autosync.
This seemed to give me a very useable system but with greatly improved battery life. Doing the above and a few other tweaks here and there have made my battery life so that it drains by about 1% overnight when not in use. I also seem to get better battery life while using the tablet. I haven't had any trouble playing games either.

I am assuming the camera is not working using this method or did you figure it out?
And also, do you have a link to the drivers you used off hand or what did you search for to find them?

Nope, still haven't gotten the camera working. We are missing some config files still. Do you need the camera drivers or the tablet drivers?
The camera drivers are : sp2518 and sp0838, though I also see a module being loaded called cam_detect
I don't recall where I got the adb usb drivers for the tablet, but it would probably be a good thing to mention in this thread so if you have them, let me know and I can add it to one of the top posts. If you're having trouble finding them, I'll remove my drivers and go back through the process to find them again.
Looking for the tablet drivers. I am about ready to tap out on this thing for a while. lol Its driving me crazy.

OK. The drivers I used were probably: VID_1f3a_PID_efe8 (or something similar)
You can either google that or try downloading the firmware for TP718AQ here: http://www.agptek.com/forum/viewtopic.php?f=22&t=948
Remove all prior drivers for the tablet. Plug it in and tell Windows to use the drivers from the extracted file you download (Will extract to TP718AQ_Update_Firmware\USB Driver).
Sometimes I have to do a little dance with restarting the device and my computer to get it to recognize it.
As a last resort you could try this: http://www.xda-developers.com/andro...r-solves-your-adb-driver-problems-on-windows/
Let me know if you have any problems.
Good Luck!
Ok, I officially give up trying to root this thing. Stupid windows will not install the drivers in both the links you provided and I cant get windows to even try to install anything after removing them then I got the android ADB drivers to install but still zero luck. All rooting apps fail. Hopefully someone will post the image of their rooted NB07. A few claim to have rooted it just fine but I cant win with this thing.
All I want is to be able to run link2sd and a few other apps that require root. This is officially the longest I have owned an un-rooted android device. lol
I'm the one that got the root working using kingo, so for the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers ( I would post a link but I don't have 10 posts yet on XDA)
That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times I've done this were for clients of mine but its pretty straight forward.
Well, I have decided that for now this tablet of mine is un-rootable. I must have tried with 5 or 6 different drivers about 20 times with each with Kingo. I even tried that other program that is all in Chinese that loads some BS app on to your phone with no luck. So, for now, I am going to give up but if anyone has any other ideas or wants me to try something or they have for sure figured out how to root it, let me know as I am happy to help the best I can.
Edit: Oh yeah, Dont know how much this will help anyone but here is some more specific specs on the Nobis NB07 tablet I pulled off it with Hardware Info 3.0.0. Feel free to put the link in the first or second post if you want. Maybe it will help a little bit more.

Thanks to the work of someone on another forum, I have now got TWRP working on our device and am hoping we will soon have a CM working on it as well. Check back in the near future for further details. Maybe if you can't have a rooted stock, we can get a fully functional CM.
I am assuming you need to have root to flash the TWRP recovery correct. This is good news. Would love to have more info on it. Are you working with people on this site or another site? I would love to follow along.

On another site for now. Just PM's at the moment so not much to follow yet. But, all you'll need is the Phoenixsuit to install it, so you won't have to root your tab first. You'll have root on the new ROM. You'll have to have drivers fully working though. Once fully working I'll link to the site so people can get the files and hopefully we can get this guy some donations for his work.
Awesome! I would go right to CM on this and skip the whole rooting the stock firmware. Would be nice to be able to root the stock firmware though then things would be so much easier. Think the camera will be working on the CM build? If not no big deal but would be nice to have them working.
Keep me (us) posted on the progress.

Not sure about the camera yet. I have CM booting but no touch yet, so this will be the first task. I'll keep everyone posted.
Any word on getting things to work yet?
Currently, we have CM working with no touch screen/camera. I'm not sure what else all isn't working because I'm waiting on my OTG cable to come in for further testing to see what all is going to be required to get the touchscreen going. Right now, it appears we my be looking at compiling our own drivers which could take some time to do. I think we'll get it eventually, but it may take some time. If you don't need touchscreen or camera, it could be working right now.
Sorry for no updates for a while. My work has been delayed on this since I have a son who is sick and in the pediatric ICU. I'll get back to work when things calm down for me.
No worries man. Family first.
Just a question, Hippie...
On the original ROM, can you see your device in ADB? If you can, and type "adb shell" do you get root? If you have adb access but not root, can you try typing sh and see what happens?
Also, could you try loading the rootfromOTA.zip and see if you can get a printout of the error log if possible?
Also, I tried installing this from the recovery on a similar ROM and it acted like it failed. I went back into the ROM and used adb and was able to get root using vroot or kingo...I don't remember which. This may be worth a shot.
Interestingly, I have been looking for alternative ways to root and found this (but we need to find a way to get to the bootloader):http://whiteboard.ping.se/Android/Rooting
I think that the method to get to bootloader is to turn off the tablet, then hold down the back button while tapping the power button 5 times. But, I also googled and found a method for getting to fastboot from adb in android without root as well which may work.
