[Kindle Fire Q&A, Help & Troubleshooting] tombombman:
I found a used kindle fire for 130 on craigslist. If you are in a big city, I would just keep my eye there.

You might spot something on ebay as well, I see buy it now for as low as 140.
[Kindle Fire Q&A, Help & Troubleshooting] aaricchavez:
I'm not looking for a completely working one, I just need one with say a broken LCD and digitizer or some other issue. And there's a mint condition one up for $90 here, and tons of others for $125. The $90 one is a good deal, but I bought mine broken offa ebay for $60, so that's what i'm looking for.
[Kindle Fire Q&A, Help & Troubleshooting] aaricchavez:
Thanks for the support guys. Just got one on eBay for $47 :D

HTC T328D blocked for telecom operators, China Telecom 3G?

Or it works with other operators of CDMA 2000 EVDO?

Can it work not only in China but also in Ukraine?

Telecommunications operator in the format of CDMA 2000 EVDO 3G.

Can someone show the practical work in another country other than China?
[Miscellaneous Android Development] vincent_smoox:
I have thats device, im live in indonesia and i can use it with my three CDMA operators its also support EVDO here
[Miscellaneous Android Development] Pritesh.mohan:
India

This device is supported worldwide.

I am using in India.

It use EVDO or GPRS on gsm sim.

I can confirm that the above method works great. Just a heads up DO NOT I repeat DO NOT mess with the build.prop file, I ended up bricking mine all because of some dumb Gameloft game. I now am on my second TF300 and highly recommend staying away from the build.prop until we have a working CWM.
[Transformer TF300T Android Development] wideopn11:
Nice simple guide. I've upgraded and downgraded. Only thing irritating me right now is that I've been able to get the OTA update and Asus cant give an answer as to why other than "keep waiting". I might be on my 3rd tablet soon.
[Transformer TF300T Android Development] ptgay49:
What about people already at .17?

First off, thank you for your original post (Post #1)!

I will get my 300 in about an hour and I would think it will be on .17. If that is the case, I will, of course, decline any offers to update to .26 via OTA message.

I assume, then, I start with Step Two and go from there. Right?

Thanks again.
[Transformer TF300T Android Development] jgaf:
The first time I turned on mine, the update got automatically downloaded but it doesn't run until you decide to. The answer is yes, just skip to step 2 and go from there.
[Transformer TF300T Android Development] bronzwarlock1225:
Yes sir, just download the sparkyroot.apk and follow the onscreen directions! Just make sure you back up the root with Voodos rootkeeper (can be downloaded from the Play Store) and then update the tablet. Once update restore the root from the rootkeeper app, and that is it! Your rooted and on the latest firmware!
[Transformer TF300T Android Development] medic999:
AWESOME! worked like a charm on TF300 .27

[Transformer TF300T Android Development] itzbilly:
I'm on 26, followed the guide completely. On the final adb reboot, the tablet reboots but there is no flashing progress bar and when I check settings, I am still on 26... can anyone help me? :\

EDIT: never mind, I didn't see that I had to go into the zip file and extract the blob file out.
[Transformer TF300T Android Development] Gam3r 4 Life:
Need some help here. Long story short I bricked my brand new 300 messing around with the build.prop. It wont boot up now. It starts at the asus screen and then goes blank. I am able to get into the different modes by using the volume+power, and I am able to see my device in adb intermittently. I was also able to pull the bad build prop from the system using "ADB pull /system/build.prop c:\". But I am unable to push the good build.prop I have back in. My question is this. Can I use the method described here for downgrading to unbrick my 300? I have no way to put the firmware file onto the internal storage, only the external. So is there someway this can be done? I would really appreciate some help. Thank you
[Transformer TF300T Android Development] jgaf:
The only thing I can think of, is to try a manual update putting the update zip in a empty sdcard and trying to boot into recovery with power+volume. If that doesn't work you will have to wait for an unlocked bootloader.
[Transformer TF300T Android Development] ptgay49:
How do I unroot?

I love my 300 after I rooted it while on .17, then saved my root, updated to .26 and then re-rooted. Unfortunately I cannot get this device to connect to my Netgear WNDR4000 router without disabling all security. I have added numerous wireless devices, including a Gingerbread smartphone, with no diffulty whatsoever. But this puppy will not connect even though it sees the SSID. So I need to return it and I want it to be unrooted and then I'll do a factory re-set.

Any advice on unrooting my 300 would be appreciated.
[Transformer TF300T Android Development] jgaf:
Not really an expert here, but I guess the simplest way I could think of is flashing a different Firmware than the one you have. Since updating from .17 to .26 loses root. After that just make sure you don't have root by running OTA RootKeeper, then do a factory reset.

You could try that or wait for a more profesional opinion :D

On another note did you call ASUS Support to see if they could help you with your specific problem? There's no way that the pad can connect to the router?
[Transformer TF300T Android Development] ptgay49:
^^

Thanks for the quick reply.

No, I didn't call ASUS Support. I don't have much faith in tech support these days.

Yes, it did connect to my router but only after I deleted all security on the router. I did that just to see if it could connect at all. However, it does not play nice with the security level I need on my router for my wireless devices.
[Transformer TF300T Android Development] wideopn11:
Has anyone tried doing a factory reset after rooting .17, taking the OTA to .26, restoring root on .26 and is able to confirm if root will stick through a factory reset on .26?
[Transformer TF300T Android Development] itzbilly:
I did a factory reset on .26 and root stuck, you just have to re download superuser app from play store. (this is assuming you saved your root with root keeper)
[Transformer TF300T Android Development] wideopn11:
Of course I have OTA rootkeeper backing up my root. Thanks for the update.
[Transformer TF300T Android Development] keynith:
I used the vipermod to downgrade to .17, then used the sparkyroot to root, and then used OTA Rootkeeper and it worked flawlessly after updating the firmware to .26. Thanks!
[Transformer TF300T Android Development] gnash.s:

[Transformer TF300T Android Development] ufmace:
This thread pisses me off!

Yeah, that's right, I'm pissed... that I didn't root it sooner because it's so fast and easy. :D If you have ADB and a basic knowledge of how to use it, this is about as simple and painless as it gets. Downgrading your OS sounds like a big deal, but it only takes 20 minutes or so and you don't lose any data or apps. I got the OTA upgrade back to .26 just about instantly too. Thanks for consolidating all of the info and links into a nice short thread!

SparkyRoot crashes on step 4 (cleaning up). I have superuser will this make a difference. Any help?
[Transformer TF300T Android Development] Spitfire:
I got this to work but I'll post the problem I had just in case someone else gets stuck. Windows was automatically installing my device as a media drive and not adb. What I had to do was change the storage settings in the tablet to camera mode, then uninstall the drivers in device settings in windows. I then unplugged the USB cable and plugged it back in. Windows installed the drivers again but this time as an adb device. After that I ran the viper script with no issue. Hope this helps someone.

[Transformer TF300T Android Development] Gam3r 4 Life:
Will this method work if your on .29? I might be unrooting and exchanging my 16 for a 32, but if for some reason I dont I want to make sure I can root again from .29. Thanks
[Transformer TF300T Android Development] jgaf:
If my pad wasn't rooted already I would do a video walk-through, sorry. Maybe someone can do one, if they haven't rooted their device yet. Since this is the same method used on the Prime, we can try searching around the net to see if someone has made a walk-through downgrade for the Prime.

I'm not an expert but I don't see why it shouldn't work. Maybe wait for a more experienced opinion. And I'm pretty sure if you exchange it, in a store, you will get one on .17, making it easier for you to root.
[Transformer TF300T Android Development] Gam3r 4 Life:
Ok, I want to confirm that I was able to downgrade from rooted .29 to stock .26 with the tool listed here. Which is just a script of wolfs method. Just in case someone else wants/ needs to do this Ill list how I did it with simple instructions. Youll need working adb and the correct drivers which you probably already have if your here.

1) Download the appropriate firmware from here.

2) Extract the zip file twice. The first extraction creates another zip, then extract that one to get the blob and meta info file.

3) Put the blob on the INTERNAL storage of your 300. I dont think its needed but I also put the meta info file there too.

4) Download the viperMOD Primer Tool from here.

5) Extract the vipermod zip file into any folder. Youll get several files so I wouldnt recommend your desktop, but thats your call.

6) Connect the 300 to your computer making sure you have usb debugging checked.

7) To make sure your ready open command prompt and enter "adb devices" without the quotes. If your devices serial number shows up your good to go. If not then youll need to fix that before proceeding.

8) Open up the viperMOD Primer Tool - Modded by bpear_v3.exe.

9) Ignore the text that says it will be installing .15 onto your prime. The tool will install whatever blob your using.

10) Press 1 enter. Youll get a message that tells you to make sure you have the blob and drivers correct.

11) Press enter again, Youll get another message that tells you to enable usb debugging.

12) Press enter again. If your all set you will get message saying it is moving the FW and will reboot.

13) After the reboot it takes awhile (for me about 10 minutes), it might seem like its not responding or doing anything but it is. Just leave it be.

14) It will reboot to the Asus install screen with the progress bar.

15) When its done it will show "optimizing applications". If you made it here your good to go.

I know this is written simple, but I remember how frustrating it was for me when tutorials assumed you knew everything. I hope this helps someone. Thanks for reading.

[Transformer TF300T Android Development] WOEHAA:
A small addition to that... my win7 pro x64 copy missed the proper ADB drivers.

So after 3 hours of trying everything, removing devices, changing settings and browsing through all the ADB related topics here at XDA I figured that an update of the drivers might be in order.

So simple, why didn't I think of that in the first place. :rolleyes:

The files I used, I downloaded from softpedia, but I think they are similar to those in the ViperMod drives sub dir :rolleyes:

I noticed that after updating the ADB drivers of the vague ADB device in my Device Manager overview, the cmd prompt (still in the background) suddenly started doing stuff.

With the new drivers, the device was properly recognized by the Viper tool and starting doing the "thing"

It is moving the blob as I type this

Fingers crossed, hoping all goes well

edit:

That go well, but then Sparky gave me hard time. Again, XDA forum is the answer.

My experiences:

Backup up an app needed to be done with the (non default) app+data checked. After that the SU also could be marked as okay

A retry of the back up needs deletion of the backup files first. So I did that and did the SParky dance once more, and after 5 tries it worked.

Then the clean up, no problems there

But OTA Rootkeeper then told me there was no root. So I installed RootChecker to verify this and indeed, no root access.

After more re-installs and files being deleted I noticed the BusyBox remark in one of the tf101 related topics. So installed that one too (the free version), rebooted the TF300 and now RootChecker says : O.K. :)

Oh yes, I also went for the SU pro version.

edit2:

*sigh* still not all items checked in OTA Rootkeeper: the "protected su copy available" is still unchecked.

What now?

edit3:

noob learning slowly how to root his TF. I appers that the remarks I read somewhere "Make sure all check boxes are marked in the OTA RootKeeper" isn't exactly true.

The first 4 need to be checked. The last one (su copy) is GOING to be checked after you select the ROOT button.

Status: all items are checked now in Rootkeeper. Now the OTA updates can be installed.

Still keeping my fingers crossed

edit4:

After OTA updates I am now on .26

So I opened Rootkeeper, saw that (as expected) the tf300t is no longer rooted, has not root permissions granted but also there is no protected su copy available (??)

Anyway, I selected Restore root ... nada. Not even after reboot. I have got once again a unrooted .26

Can anyone tell me where I went wrong? What am I missing?

Well, that was an entertaining 6 hours nonetheless :)

edit5:

What was that again about the C40KCT device number?
[Transformer TF300T Android Development] Lanemc:
Am I Bricked?

HELP!

I rooted my 300T with Sparkeyroot, unlocked with the ASUS utility. All was good, then OTA to version 26 software and lost root. I then used method two to load the version 17 BLOB file. all went well until I completed the action then rebooted. I initially got a bunch of errors for missing folders, then it rebooted and I am sitting at a "Unrecoverable bootloader error" If I hold the power button about 10 seconds, it apparently power cycles and comes back to same error message. Apparently i can't power off either, it goes blank for a few seconds then lights up and shows the error again. Anyone have any suggestions??
[Transformer TF300T Android Development] costcutter:
Not sure why you used the unlock tool at all?
[Transformer TF300T Android Development] WOEHAA:
Okay, I think I figured it out.

After SparkyRoot and Voodoo OTA Rootkeeper there is a su-backup file in the \system\ directory.

Just to be sure I copied that to the sdcard

After an OTA this su-backup is deleted and (of course) I cannot put the copy back in the systemdir.

How can I counteract the deletion of the su-backup file when there is an OTA?

I really like to have ROOT on my TF300T, so I can use tools that require root. Any help would be awesome.
[Transformer TF300T Android Development] rickpref:
Trying the one-click method but it looks like it won't recognize the firmware file...I'm on .29, it starts and looks like it does everything fine but when it says transferring firmware 3-10 minutes it goes instantly to the next step and says everything is done but when it restarts it didn't flash anything. Do I need to downgrade to .26 first? I so, where can I get the .26 blob, it looks like Asus took it down from their site.

thanks
[Transformer TF300T Android Development] jgaf:
Once you use rootkeeper make sure every box has a checkmark, if they do you will have a root backup that can be restore after an ota. After ota just run rootkeeper and restore root with it

Are you sure that the blob file is in the internal sdcard? AFAIK you can go straight from. 29 to. 17. Double check where you placed the blob file, remember you just need the blob file not the whole firmware zip.
[Transformer TF300T Android Development] rickpref:
I did not put the blob file by itself....I put the zip. Don't know how I missed that.

thanks
[Transformer TF300T Android Development] Xnergy:
I downgraded my dutch TF300T successfully from .29 to .17 and now i got root :D

After that i used OTA rootkeeper to backup root, all checks are green.

It updated to .26 first, after that it upgraded back to .29 again but i cannot restore the root. :( Don't understand why, this is the third time i downgraded and attempted to root again with .29

---------- Post added at 08:40 AM ---------- Previous post was at 07:56 AM ----------

Maybe i have to restore the Asus backup first made with Sparkyroot?
[Transformer TF300T Android Development] Xnergy:
Restoring backup does not work i just found out..
[Transformer TF300T Android Development] WOEHAA:
@jgaf

I did exactly that. All items were checked, there was a su-backup file in the system directory.

It's just that the OTA deletes the su-backup file. And there is no way to put it (the extra copy I made) back into the system directory.

Therefore OTA rootkeeper has nothing to work with, ergo cannot restore root.

So in fact everything works, until OTA destroys the su-backup file.

@xenergy I think you have the same issue I'm having.

Could you check if there is a su-backup file in your system directory, right after you used OTA rootkeeper?

And check again after the OTA?

I hope there is a fix for this. Not some tweak from Asus in the OTA.

Root without having to deal with custom ROM is really the thing for me.
[Transformer TF300T Android Development] WOEHAA:
@rickpref the instructions clearly state you have to unpack the zip twice.

Only put the blob file on the sdcard. Not a zip file
[Transformer TF300T Android Development] Xnergy:
Started the whole process over again for the 7th time now, and every time OTA Keeper has no Protected SU copy available ..

I must be doing it wrong or forgetting something.

Asus backup won't work either.
[Transformer TF300T Android Development] WOEHAA:
Maybe some of the more experienced ppl at this forum can confirm this, but what I saw on several youtube movies, the "protected SU copy available" item does not need to be checked. It becomes checked after you click the button to protect it.

I must admit I am still puzzled by this, since the instructions clearly state "all items" must be checked.

Nevertheless, I have the su-backup file after I finish the OTA Rootkeeper app.

(It just doesn't stay there after the OTA to .26)

Can anyone confirm this thing that the last item gets checked AFTER you protect the SU file by selecting the button?

:confused:

The reason why my TF300T cannot be set to root after the .29 OTA has to do with the WW version of my tablet (read it in a different thread somewhere on this forum). It is said that at this moment I can only get root through the unlock procedure (which I do not want, not now at least)
[Transformer TF300T Android Development] Xnergy:
Yes when i'm on .17 and i have root access, all the items are checked after protecting root with OTA Keeper :)

But when i'm on .26 or .29 the "Protected SU copy available" is not checked. :(
[Transformer TF300T Android Development] gasingvar:
Confirmed.

The /system partition is most likely formatted when upgrading from DE .17 to WW .26, which means the su-backup file is removed.

I even tried putting the backup file with a different name all over /system/* and chattr:ed them (like rootkeeper does) (Do NOT try that at home. There were some pretty scary moments), and all my copies disappeared.

I would like to find a .17 WW (NON DE) or a rooting method for .26.
[Transformer TF300T Android Development] David Dee:
Guys, unfortunately those of us on WW, who have upgraded from .17, can only accomplish root (with a locked bootloader) by downgrading to DE .17, or US .17, and staying there. Any OTA will remove root, even with Voodoo OTA rootkeeper.

There following are the three ways for WW ppl to keep root and update to the latest version:

1. Unlock your bootloader and flash .29 rooted zip file - voids warranty.

2. Do not accept any OTA's when you purchase the tablet, root your .17 WW, install Voodoo OTA and you will maintain root.

3. Someone will hopefully find a WW .17 blob (none available today) to downgrade too. I am keeping my fingers crossed for this one, but each day I get less hopeful.
[Transformer TF300T Android Development] jgaf:
That sucks, it seems that when the firmwares get converted to ww you cant restore root. If you guys are willing to try one more time, use the US firmwares and try to update manually hopefully root will stick.
[Transformer TF300T Android Development] David Dee:
Unfortunately root keeper only works for ota, so root will be lost on a manual update.
[Transformer TF300T Android Development] jgaf:
Yeah I know, but apparently I have read some people saying they were able to keep root after doing manual update.
[Transformer TF300T Android Development] David Dee:
Wow, didn't think that was possible.
