There is no update available TF101 - Eee Pad Transformer Q&A, Help & Troubleshooting

Hi there,
I read almost every thread about no updates available and still don't found answer...
My tab was rooted and CWM installed.
because this is B60, I used NVflash to flash totally stock 8.6.5.13 from here:
http://www.tabletroms.com/forums/tr...stock-3-2-recovery-roms-unbricking-tools.html
after that, I tried to use "system firmware update" but "There is no update available" message appears,
so I decided to update it manually, put 8.6.5.21 zip on sdcard and now have 8.6.5.21 android,
but still "There is no update available"...
I also tried to root this 8.6.5.21 put CWM again, used SuperWipe Full script, and again installed 8.6.5.13 with NVFlash, still same situation.
I also tried tricks with clear cache/data of CMClient and DMClient,
I can push ICS via NVflash but last version i found is .24, i tried this also, but can't get update to .27 and noticed battery draining during night,
my plan is come back to totally stock where OTA will work and give this tab to my wife.
Anybody can help me ?

Use BRK's tool and download the latest firmware from Asus. This tool works great and will even get you rooted after nvflashing 9.2.1.27 for you.

BRK tools is great "Everything in one place" tool.
I can use it to install ICS .27 from Asus web site, and this is great,
but I don't know if in the future OTA will come...
I tried to install 8.6.5.21 using this tool, and after that still had message "There is no update avaiable"
as I wrote, want to be 100% sure, future OTA will come.

My understanding is that FOTAs will be allowed if you nvflash a stock firmware with this tool, so long as it's not rooted and you keep the stock recovery. All has to be stock and the proper SKU, i.e. US, WW, CN, etc. and it should work the same as if it came from the factory that way.

I have a rooted, deodexed stock(ish) rom and I still get updates, but of course they won't flash. I don't think ASUS is constantly pushing old updates since the only ones who haven't upgraded yet are either rooted or haven't used their tablet. The updates are incremental, so you need the current stock rom to update with the lastest OTA. The full roms can be downloaded from the ASUS site.
If you want to get updates straight from ASUS, then flash the latest rom and keep it stock. Otherwise, you'll just get useless updates that won't flash. You need a stock system and a stock recovery to flash the ASUS OTAs. No voodoo, no overclocking kernel, no CIFS/SAMBA, no XBMC, no nothing, no fun.

Exactly! Rooted rom or changed recovery don't stop to receive FOTA notifications, but will give an error if you try to install.

Something is strange here, and probably only Asus knows how it works.
I had rooted room, and my tab downloaded first update to ICS version, but of course I didn't install it. Now I tried to come bace to fully stock, tried 8.6.5.13, 8.6.5.21, and 9.2.1.24 and never received FOTA notification anymore.
Maybe my serial number is banned on Asus side ??? Who knows...
I spend a lot of time reading and some people had this problem, some not, nobody don't know the reason.

I tried to come back to fully stock in order to give this tab to my wife, but if tab don't receive FOTA anymore, and I'll have to update it by hand every time using SD card it makes no sense to install stock firmware. Now I'm looking for most stable ROM and will install it. For now the winner is newest ARHD, but I still reading about diffrent roms.

To be clear, I think that ASUS only pushes out updates for the latest ROM. If you are on .24 or older, you probably won't get an update since .27 is the latest. This is just my theory. The updates are incremental, which means that you have to apply the .27 update on top of the .24 rom. It will fail if you try to flash it over an older rom, even if it is bone stock.
In your situation, I would recommend a custom ROM.

Gee one is right... once you root stock update won't install and yes its a incremental update and you can't install .27 over .21 it has to be in order (.21->.24->.27)... also you need a unrooted ROM to download and apply updates from Asus otherwise update will fail and u risk soft bricking ur tablet... I did that once coz I was having problems with 1st ICS versions....
If don't like/can't get to work then root it and install either android revolution HD or revolver ICS.. both are stock based ICS ROMs...

Hmm...
Updates are incremental, this is true.
but... When i bought my tf, and come back to home, FOTAs coming few times and after one hour about I had nevest version.
Now, after NVFLASHing .24 I don't receive FOTA update since two days...
Somewhere I red, NVFLASH don't clean everything, maybe this is reason.
I would like to try, but i have no idea how to TOTALLY clean my tab,
I looked into SuperWupeFull script and it clean mmcblk0p1, p2 and p7.
Any idea about TOTAL clean ?

really dangerous way should be to execute dd if=/dev/zero of=/dev/block/mmcblk0
but i don't know if it is good idea ))
this could break apx mode.

Why don't u try downloading older version of Asus and do incremental update.. say first version of ICS for transformer...
Sent from my Transformer TF101 using xda app-developers app

I tried versions, ICS .21, .24 and HC .13, .21.
Every time, same message:
"No updates available for your device"

Asus might not be pushing any updates. I bet they stop as soon as they post the latest rom on their website.
If you use nvflash to reflash your TF, it will format every partition, but you have to use the --create flag. If you just download the system or recovery, it won't touch the other partitions.

If I rooted and installed revolver now...

Hi I had a question. If I got root and installed revolver would it still be possible to upgrade to ICS when it comes out? I have heard alot of issues of people not being able to do OTAS after this. Also is it possible to remove revolver and got back to stock?
Thanks
After rooting you cannot install any OTA's, but if you run revolver you will most likely see an update to ICS considering the owner keeps it updated. He releases new firmware updates to his ROM the same day they are released from Asus.
If you root though know what you are doing, and yes you would be able to flash back to stock.

I see. I've done a bit of rooting with the archos 101 and i'm pretty good with computers. You said you can't do OTAs but asus puts the files on their website don't they? Couldn't you just dl it there and update?
you can download it but you get an error when trying to install I believe. I've just updated through the roms that were released. These guys are right on it, and they're good!
Yes, you could.....but it won't work, and will automatically fail mid-way through. If the update detects any software tampering and doesn't appear to be a stock unrooted build it will fail. Like I said though, ROM developers are good at updates, they put them out daily and we are sure to see a ROM of ICS before it is even out officially for our tabs.

Without nvflash how can we revert to stock? I'm on a tf101g b80. Sry if i post it there.

[Q] Can the B90 Transformer be downgraded from ICS to honeycomb???

Header says it all... and if the answer is YES, then a link to HOW to accomplish that would be greatly appreciated...
Many thanks...
You would need to root, install cwm recovery, flash a rooted HC ROM.
@basballfanz: how to root the 9.2.2.3 Firmware?
From my experience, once you are on ICS, re-flashing Honeycomb via CWM does NOT solve the reboot issues (you'll have them in Honeycomb too). The ONLY way that I was able to return to a stable version of Honeycom was to NVFLash a stock honeycomb image and go from there. But, since you have a B90, you can't NVFlash, so basically, I think you're screwed at this point....
There is a whole thread about returning to honeycomb via CWM and still having the reboots, etc.. Search it out...

Don't think there's a way right now.
Can't you modify/use an ASUS Ota update package and use the stock recovery to 'Update' to HC. Reboot issues will still be there though.
Edit: as in when downgrading for razorclaw root etc

You can't downgrade on a stock tf.
The trick going from 8.6.5.21 to 8.6.6.19 to use razorclaw is technically an upgrade not downgrade. It was going from 8.6..5.21 to 8.6.6.19
Sorry I wasn't clear, I mean modifying a downgrade ASUS package to trick the Tf into Thinking that it's being updated.
Thanks for the version # clearup though X.x"
a simple rename do not work. Have taste it....
The tf see the update, reboot and start Update. But stoppt...
So what to do? Edit buildprob? Or what read the tf in Thema Update file ?
Get a hc package, unzip the ics package, delete and replace as needed. Probably need to edit build.prop too, and make sure the kernel flashes.
Or is a replace of the blob file the onky we need?
How is the chance of bricked?
Considering the kernel/os differences, higher than you'd want it to be, so I'd only do it as a last resort. Make a nandroid backup before doing any tinkering.
Cant do Backup without root. Thats why i want to downgrade...
Seems like a new method to downgrade from ICS to HC even for the non rooted users.

I think the real question here is why would you want to downgrade to HC from ICS? It's pretty well known that a full system restore fixes most issues.

Why? Because ICS is completely un-stable on ALOT of TF101's (if not all). Honeycomb was rock solid.

First letter:
B=2011 & C=2012 manufacture year.
Second letter/number:
1=Jan 2=Feb ect till Oct which is A(hex)
So your C3O was manufacture in March 2012.
Only different is the SBK
ASUS changed the sbk mid July 2011.

[Q] Update available but nothing happens

Decided to return to stock and try 9.2.2.4 update (currently on 9.2.2.3 WW), in settings-info-firmware update it says that the update is available "check notification area" but nothing really happens. I can notice that some other message is "flashing" from behind, "server busy, try again later" or something like that.
Ive read about the update rolling out in Italy and some other countries in Transformer General so the Asus servers shouldnt be down.
Is anyone else experiencing this? Or something has gone wrong when I was flashing the stock ROM?
Stock rooted? Or did you nvflashed it stock unrooted. Cause i had some sort of problem when i sented it for repairs. When it came back i wanted to update it to android 4.0 . And as everyone i know had there updates i still had none.

Rooting Newest Firmware Update?

Hey all, just got my TF700 on Friday. So stoked.
I am about to root my tablet, but I want to make sure the current tools with work (sparkym3 and Debugfs) with the newest update. I would rather root the latest release than root what I have and use Voodoo. I have had issues doing that in the past.
My current firmware is IML74K.US_epad-9-4-5.26-20120720
How many update as I away from current? Will the current tools work with the most recent updates? Which method do you guys recommend?
Thanks!
I have not been able to get those two methods to work for me on the newest update. I think I am a rare exception, most seem to have success. I have even returned a tablet becuase of defect and the second would not root either. It wasnt a big deal because i knew i was going to unlock the bootloader and then i could install a custom recovery and rom and achieve root that way. If you are planning on unlocking I suggest you do a little more research in the NVFlash page because if you update from your current firmware that will no longer be an option. Just my 2 cents
(Imo) i would just root what you have now and use voodoo. Checkout the nvflash thread while your at it. ( doesn't work with .30 update, i wish i had noticed that before i upgraded to .30 )
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
I know it was mentioned but just for good measure... If you plan on unlocking at all make sure you do it before upgrading to .30 so that you can get nvflash setup for your device.
Sent from my Transformer Pad TF700T using Tapatalk 2
Is .30 the next update? How many update am I away from current?
I have some thinking to do, I wasn't planning on unlocking (at least until CM and AOKP officially support the TF700) but if NvFlash won't work on any other updates I may need to rethink.
And to be honest, I don't really see the purpose in unlocking. I ROMed my TF101 but ASUS does such a good job of only altering AOSP with small (and beneficial) changes I may just leave my Infinity as is. Especially if I have to stick with the shipped firmware and once I update NvFlash won't work. I guess I can always just flash ROMs without NvFlash though...
But my two questions above still stand.
One more question as this is the first device I have owned that had NvFlash available. What is the benefit of having NvFlash vs just CWM? Just protection in case I do something really stupid?
Sent from my EPAD using Tapatalk 2
You are one update away from the latest which is .30. (soon to be two) The debugfs root method will root you.
you should check out my thread on root and jellybean: http://forum.xda-developers.com/showthread.php?t=1908304
Nvflash allows you to flash anything even if the bootloader is corrupted or prevents it, it also allows you to downgrade when the bootloader prevents it e.g. .30 to .26. it is also required to flash custom bootloaders which is useful if someone develops a dual-boot bootloader. You can even relock and reunlock your bootloader with nvflash. If you don't plan on using non-stock fw though, stay locked so that you can get your updates and support.
Thanks for the help guys.
So what I'm thinking is just to root, unlock, and NOT flash NvFlash. It isn't terribly dangerous not to use right? I mean as long as I have CWM installed I am pretty safe unless I do something completely stupid right?

If you have .26 and are going to unlock, you may as well create your nvflash files. It isn't so much as flashing nvflash. Nvflash is already hardcoded in the tegra chip. You would just be creating the encrypted files needed to utilize it on your device. You save these in triplicate in case the worst happens. Unlocking is necessary for generating the nvflash files, but it voids your warranty and leaves you unable to recieve OTAs (you can still update manually using methods listed in the development forums).
I'm not explicitly recommending that you unlock, but if you do, it's best to do it on the .26 update, so you can get those nvflash files from your device.
So if I do install NvFlash can I still waiting install official updates from Asus by downloading them from Asus website?
I really want to try Asus's stock Jelly Bean ROM, so anything that removes that as an option is not for me.
Thanks for the clarification.
Sent from my DROID SPYDER using Tapatalk 2
you don't install nvflash. you use it to interface with the device's apx mode.
as for the official firmwares, you can still install those even if you are unlocked. you just have to do it manually.
Yup, you can just download the firmware zip from asus's website:
http://www.asus.com/Tablet/Transformer_Pad/ASUS_Transformer_Pad_Infinity_TF700T/#download
Unzip it once(it'l be another zip) and flash that in TWRP. (not sure if it works in cwm. I am biased but I definately recommend twrp:angel Make sure you uncheck flash recovery. reinstall recovery using fastboot because the update deletes it.

No, you need to unlock to take a bootloader backup, which you will not able to take OTA Jelly Been, however, you can download the new Jelly Bean from Asus website and manually flash it.
OK I feel like I understand now. There really aren't any downsides to setting up NvFlash (Asus warranty not an issue, I have Best Buy's super program where I can return the tablet even if I just scratch the screen if I want to).
My initial impression was that if I unlocked I would not be able to update any stock firmware period, and that if I set up NvFlash I could not move from .26.
If I understand correctly I just have to be on .26 to set up NvFlash, and can manually install official Asus firmware after unlocking.
Thanks for the help all! I am not new to flashing ROMs etc. but have never had the ability to use NvFlash.
Have a great night all!

[Q] In what order did the updates come

I am doing an incremental update of my tablet and I need to know what the chronological order of the updates where. My tablst came with 9.4.5.26 and I see references to .16, ,18, .30 etc. Which ones do I need before I can do the 10.4.4.20 update. I'm not sure but I believe I should do the .30 next. If so can I use the WW.30 update because the thread I am using to do this only offers it and not a US.30. Still new and do not know the difference, if there is one.

The order is .30, .16, .18, then .20. Incremental is nessessary to retain root. If you unlocked, you could flash the full version .20 and done.

Thank you, how about using the ww.30 update is that okay? There is not a link to a US .30 update. Do not want to unlock at this time I unlocked my first TF700 and rooted it but when I tried to setup NVflash I ended up bricking it. Thankfully I was still with in the 30 day Amazon return period so they sent me a new one. I am now out of the return period with this one and if I brick it now all I will have is a $479.00 door stop.

OTA updates must be done on the same SKU - if you start with an US firmware, you must continue with US dlkpkgs.

Haha, but if you unlock, you wife will be a lot happier!! Actually, unlock is very safe and even less risk than rooting. Either it works or just fails. With the poor performance of the tf700, it's a huge different if you unlock and install Cleanrom. Anyway, you don't do .30 incremental update and no, you can't use WW instead of US. Since there is no US file, you should do a Full version update then do root and then do incremental from there on. Here is link for full .30.

My tablet came with US 4.xx.xx.20 JB and flashed US 9.xx.xx.30 ICS by renaming zip file and copy to root of sd. Did this so I can root ICS. After I downgraded I was prompted with OTA to JB 4.xx.xx.20. I rooted first of course and installed OTA rootkeeper and after the OTA finished I restored root via OTA rootkeeper and didnt have any issue with jumping straight to JB .20. Although I hated JB on the tf700 as it caused so much lag so I flashed back to ICS .30 which is the only version that will work via micro sd card method.
I'm wondering why the need for incremental upgrade?

Yes, it's the best way while you already rooted, then unlock. Once you unlocked, it's very simple to do the rest. Just install custom recovery (TWRP) using Goomanager app from the market, then use this to flash prerooted rom like Cleanrom/kernel etc...
The most common mistake ppl bricked their devices was flashing the wrong recovery or using wrong tool to flash recovery. Other wise is pretty much brick proof.
dlpkg file is incremental update, it will not wipe your stuff (same as OTA update) and you could preserve root with Rootkeeper. Firmware download from Asus site is a full rom upgrade, which will wipe everything before upgrade, included root, apps etc...
Rooting is not really help with tf700 performance issue. I recommend you should unlock then life is beautiful after that.....

My tablet came with US 4.xx.xx.20 JB and flashed US 9.xx.xx.30 ICS by renaming zip file and copy to root of sd. Did this so I can root ICS. After I downgraded I was prompted with OTA to JB 4.xx.xx.20. I rooted first of course and installed OTA rootkeeper and after the OTA finished I restored root via OTA rootkeeper and didnt have any issue with jumping straight to JB .20. Although I hated JB on the tf700 as it caused so much lag so I flashed back to ICS .30 which is the only version that will work via micro sd card method.
I'm wondering why the need for incremental upgrade?

In your case, you already have everything installed (JB 20), like JB boot loader, drivers, firmware etc.. So when you downgrade, most of the stuff remain in your tablet (JB bootloader remain intact etc..). People that never upgrade before and they only at .30, the right way is to upgrade one version at a time, this ensure you don't miss anything.
Good to know. Thanks
