When the ics upgrade comes - Thinkpad Tablet General

Hi
My question is this, if we have root on the tablet and lenovo release the ics upgrade will we still be able to use rootkeeper? I ask this because reading around upgrading to ics seems like its going to be a matter of copying a load of apk's I am very used to windows and an upgrade of that would sometimes keep all the settings and some times give you a fresh install.
If the root backup is kept in the system xbin folder will that get erased when the upgrade comes out?
Cheers

Ics is completely different then hc, so don't think current root is kept, all files will change.

Once you have root it is basically always possible to upgrade and keep root. OTA Rootkeeper specifically may not work because it keeps an su-backup file on your /system partition so any update that completely formats /system will delete the backup and prevent re-rooting. The ICS update may be such an update since it is a whole new OS version rather than a small incremental update with patches and bug fixes. However, with root and CWM recovery you can install modified update.zip files not signed by Lenovo. All it takes is someone to modify the update.zip to keep root or install root with the update. I did a crappy hack job on the last update to flash it in CWM Recovery with root but hopefully someone more knowledgeable will put one together for ICS. If not I'll throw one together again and hopefully it will be better this time around as I learned a thing or two doing the first one.

Thanks very much for this, I am just about to get an sd card so will hopefully get cwm soon, so I can get a full backup, lets hope we can qweek the update script as I tend to prefer stock rooted roms.

I am very thankful for the "crappy hack job" you did on the last update, and will happily accept any other hacks you are generous enough to provide.
Thanks again for all your help. My TPT has never run so smoothly.

we will dance.
Oh, there was actually a question.

You can also just choose to skip any future OTA from lenovo. The CM9 port is already in the works. When the official update and source (please...) are released, the TPT specific binaries will only make that port (and any other rom) better. In fact, maybe those devs are already ahead of the game.

[Q] Take 7.014.1 update before rooting ?

I've got a new A500 and I intend to root it soon, but I would like advice on whether to take the current update 7.014.1 being pushed before I go through the rooting process? It currently shows having 3.2 OS version.

Doesn't matter, the only way to root it is by flashing it which wipes it totally clean

My concern, being still in the middle of researching just how to root the A500, was whether the update would have a similar effect as, for example, the more major update from 3.0 to 3.2, which, as I understand it totally changes the procedure used to achieve root. But if it won't matter one way or the other, I might as well take the update in the interim. I keep hoping to see a more simple 'one-click' style of root made available before I tackle this task. So far I've found something like 3 different ways to root the tablet between this forum and another. But each is a rather involved process.
Thanks!

I downgraded, rooted, and then flashed the stock ROM without wiping. If going to any other rom, you might need to wipe.
There currently is no way to root a stock 3.2 or later tablet with a simple one click. In the past GingerBreak gave us that ability but since has been plugged. The other thing causing issues is ACER locked the boot loader making it difficult to flash in a new boot image to get to root.
=== 411 on rooting ===
So, if you have a tablet and want to root it then you have to start looking at security holes. This is what the GingerBreak exploit did along with others. But, ACER plugged those holes and as of today, nobody has found anymore.
So, you might look at exploiting an update.zip. These are OTA's that run but they are signed by ACER. So you can take it apart (unzip) and modify it, but you cannot resign it with an ACER Key. Therefore, you have to sign it with your key. Since it is NOT signed by ACER, the ACER recovery will not install it. So, you have to replace the ACER recovery with CWM which will install any update.zip regardless of who signed it. You just need to change the built in recovery by flashing in CWM recovery.
Lastly, you can just change the boot image and add root. This is easy and straight forward to do. This is just like making your own custom update.zip. Once you have your custom boot, you can then just use Nvflash to flash in your custom boot.
Now, fast forward. ACER (can someone please explain to me why?) decided to lock the bootloader thereby not allowing you to replace the recovery, boot, or any other area. Meaning, you cannot use Nvflash anymore without a key.
With the bootloader locked, you can only load new images if you know the key used to lock it. Of course, they use a public and private key combination, and they appear to use the serial number of the USB device as part of the public key making the keys on my tablet unique compared to yours.
With all this said, this ends all the easy simple rooting methods because first, they've plugged all the security holes (which they should do). Secondly, they locked the boot loader making it very difficult for people to just flash in a rooted boot image.
Armed with this, how do you root a 3.2? One way to do it is to get to a version prior to 3.2 loaded that has a security hole or does not have the bootloader locked. You now exploit it and get root. Now, with root access you make a 'backdoor' that only you know about which allows you to get into your tablet as root. With this done, now roll your tablet forward apply all updates. Since you have a 'backdoor' you can always gain root access.
Unfortunately, this gets to be messy or can be more difficult to do than just clicking on a GingerBreak application. However, if you follow the steps posted here in the forum, it's straight forward and easy enough to do. If not, you are going to have to wait for someone to find a hole and build a oneclick application. I wouldn't hold my breath on this, it probably will never happen because everyone is working on ICS.
Lastly, everyone should write to ACER, refuse to buy ACER (or any tablet) that doesn't allow you (AS THE OWNER) to change it. How would you like to buy a Ford to just have Ford lock the lug nuts on the rims so you could NOT put on your custom wheels.
I believe failure to allow owners to unlock these devices will be the downfall to Android. Windows 8 does NOT have such restrictions and businesses are not going to use devices that are locked and cannot be customized for business. Because developers write software they can sell, they'll move to Windows 8 and drop supporting Android and all these goofy flavors and restrictions. Android might be great and everyone hates Microsoft, but software vendors are going to NOT want to support all these devices.

Hi, and thank you VERY much for posting such a nice explanation, especially in addition to all the work you have done posting your thread rooting 3.2. I understand, and completely agree with your explanation, as well as your position on taking control of what we bought and paid for. I take even stronger offense with this tablet's bootloader being locked than I do on my phones. This is not a discounted phone with a service plan tied to a cell provider. It has WiFi, but " I " am the only one providing its data (it never leaves my home). There is no justification here that I am 'leasing' a provider's technology . It was a gift, so I can't speak to choosing the vendor. But I like your wheel lug analogy.
I've been reading the threads on rooting, and both my Android phones are rooted and ROMed, so I've been around the block a couple times from the rooting aspect. But thus far I have been rather confused as to which route to take with the tablet. I don't want to be limited to using terminal for su access, so I want to 'fully root' the tablet. My goal is to allow apps like Titanium Backup, Root Explorer, and others I use on the phones, as well as having Clockworkmod Recovery, or similar recovery capable of working with nandroid backups. But for now I don't have plans to use a custom ROM. So having rooted stock 3.2 would suffice.
Although I do fully understand the need to research these kinds of things before jumping in, I also know that often times information evolves, and lengthy threads which were once considered current info end up not getting updated during that evolution. This can lead to wasted time reading information which can no longer actually be used . So in the spirit of pursuing the most current info, could you recommend which thread I can use to get the best results while rooting this 3.2.1 OS Tablet with the above goals in mind?
Used Timmydean's method, it is pretty easy as long as you follow his instructions with in the zip file he has made with all the tools you need inside of hat zip file. You root, install super user and busybox then download Acer recover installer and that will install cwm...

Good luck and thanks again timmydean for this method.

Thanks, that sounds like the way to go. I'll head over to the link you provided.
I've got a couple of questions about the zip file at that post. I want to download that to my PC, and will be using ADB from there, right? I have the choice of doing so from either Windows XP SP3, or Windows 7 Home Premium. I read in older threads that many of the problems people had were only when they used XP, but were avoided by using Windows 7 (which was exactly opposite of what people experienced rooting the LG Ally), so it seems that in this case it is desirable to use Win7?
I presume I'll need to install a driver so the PC can 'see' the tablet. Is one provided in the tools, or do I need to download that somewhere?
I used windows 7. Yes the driver is in the zip file. I unzipped the file to a folder on my desktop and went from there.
In the zip there is a folder called usbpcdriver. Run the set up from within the fooder to get your driver... please read the instructions that say read me..
Sent from my A500 using xda premium
Thanks. I intend to read everything I can get my hands on before I actually start this. I definitely don't want any trouble or, heaven forbid, to brick the tablet.
pretty easy i think... good luck and let us know when you get rooted
I'm not finding any actual instructions on the steps to take for this procedure. The readme file in version 3 zip file only talks about "changes" from whatever the original procedure was.
Where can I get the actual instructions for the entire procedure?
Edit: I just downloaded version 2 of the zip file. In that one there is an additional PDF called "Steps". It is a little more detailed, and says at step 20 that "you should now have 3.2 with a SU shell installed". Does the DotNetDetector step actually ROOT the device? That seems simple enough, but it still has no mention of things like installing ADB and the PC driver. I located the actual thread from which the single post was derived (the target of the URL above, where it is suggested I use TimmyDean's procedure). I am now looking through that entire thread to try to sort out where the instructions are.
AHA! Post 119 of that main thread says "Also the instructions and everything you need are in earlier posts.".
It appears this procedure needs an instruction manual written to consolidate all the gathered information. Having a link to only the download zip files isn't telling me the whole picture. I'll try gleaning the thread and see if I can put together all the steps needed from start to finish to make this work. Looks like ROOT ain't happening tonight.

good luck man. Iphone is jail broken
OK, so it looks like the file you just sent me a link to is the same one as the "Steps.PDF" file that was released in Version 2. It appears to me that what I need to do is blend the changes (detailed in version 3's readme file) into that original Steps file, to make a single contiguous set of instructions, and then start at the top. I notice it does mention installing the PC driver and ADB.
Do I have this right so far?

That was fast! Wanna do my tablet?
The link you sent just now is to the version 3 zip file posted on 12/25, which is what I had initially downloaded. It does appear he streamlined the procedure, but it is that readme file which leaves out the part about installing the PC driver and ADB in the beginning, and also leaves out the part at the end telling you that you should now have 3.2 with a SU shell installed.
Please understand that I want to be "fully" rooted, not just have the ability to gain an SU prompt in terminal. Will this procedure "fully root" the tablet? I'm confused by what he means saying "SU shell installed".
Yes if you use his v3 file you will be.. you will need to down load acer recovery from the market after you are rooted and then flash clockworkmod.. this should all take you about 30 min if that...

OK, thanks!! Rooting went well without incident. I just installed Root Explorer and Titanium Backup, and made a backup to SD of my apps and data. Then installed Acer Recovery Installer, and let it install CWM Recovery. But what is considered the "home" button on the tablet?? Is it the reset button? The only buttons on this thing are the Volume rocker and the Power button. ( I got brave and found out it is the POWER button ).
Edit: To clarify, I meant to ask which button serves as the Home button while you are IN the CWM Recovery environment, not while in the Android OS home screen.

[Q] Ideapad K1: Creating .img files from OTA

Alright, now I realize this is the Thinkpad section but there doesn't seem to be an Ideapad one. I've been out of the Android game for a very long time, and finally came back with a Lenovo K1 Ideapad.
My big issue is I don't know how to create a system.img, boot.img or recovery.img from the Canadian OTA zip on the Lenovo site so I can flash them onto my tablet. I managed to use the root tool available in the development section to root my tablet with a US firmware. However after experiencing a lot of freezing and my tablet not responding, I felt as if I should revert back to the Canadian firmware. My problem is I forgot to create backups for the previously mentioned images so I can't flash them back and restore my tablet.
If someone could please explain or even direct me to where I can learn the steps in creating them (I just installed linux because so far it seems like that would be the first step), it would be a great help. I took the img files from a different root tool and tried those, they changed the system to a chinese firmware but I at least know it works if I could get the Canadian ones. I can go back to the US one if I really wanted but what I want is to just put this thing back into its original state that it came in.
Even if someone could just post those files, it would be greatly appreciated. I've been scouring the internet for days to try and gain some enlightenment, but it isn't happening. Probably since development on this thing isn't as hyped as others.
Thank you.

On the K1 you cannot. Lenovo has it locked down so there's no way to back it up without root. The only way to root it is to flash it which wipes it clean. Thee ole catch 22.
Now, if you read through the leaked keys and rooting tips, they talk about fastbooting to ASUS boot.bin and then backing up before you start rooting. It definitely works to backup, but I haven't found anyone that has successfully used them to restore from and I could not get them to restore. So, in my opinion, that backup method is worthless because you cannot use them.

In Linux, you just mount system.img and then read and write to it. If you are using Windows then you can download drivers that let you mount the the system.img as a disk drive.
I use Windows for everything, no need to use Linux. For cooking, Google Cygwin which runs on Windows and is kitchen for 'cooking ROMS'.

Alright thanks timmyDean for the answers. I noticed you uploaded a tool to revert back to stock. So I was thinking of giving it a shot. I'm just hoping it won't be too much of an issue if I install the US rom. I'm thinking it won't let me use OTA updates since I'm in Canada, but I can probably just do the manual method for installing the updates. The box for my K1 says US, and we usually get the same pieces of hardware as the states with just a modified OS.
Hoping this works, fingers crossed

I loaded a tool to goto CA stock too and already tested it for you.
Thank you so much man, I just used your tool. Flashed the stock US, then put my CA one and it worked like a charm. You've honestly made me so happy.
Too bad the K1 in Canada is still at 3.1 and doesn't look like it'll get 3.2 (fingers crossed we for sure get ICS).
Anyway I am very thankful. I've looked over the tools but I don't see a lock thread option, hopefully a mod will do so promptly.

[Q]Won't update to Android 3.2.1 over FOTA / need original stock ROM

So first of all my tablet is brand new and not rooted and I don't want to root it.
When I got it I could update it instantly from 3.0.whateverwastheversionatthetime to android 3.2 (build 7.006.01_COM_GEN1) but it won't go from there to 3.2.1 which I hear is available for my location (France) The update tool tells me that my firmware is up to date.
I've tried a factory reset as advised by Acer customer care services but it wouldn't change. Also no matter what I do (empty cache etc.) the market won't update to Google Play Store and I think the two issues are related.
So I have two (or rather 3) questions:
1) Does anyone know a way around to force the update? (I doubt it's possible but hey "l'espoir fait vivre")
2) If not can I install a stock ROM without root and NOT compromise the warranty?
3) Where can I get such a ROM? I have searched here and here but 3.2.1 is not on the first thread and the links on the second thread are broken, plus I want to make sure that the ROM is the proper one for my region and that comes the ICS OTA update I will have no troubles doing the update.
Thanks in advance to those who will answer.

1) No you cannot force an OTA
2) It depends - others have reported returning there acer with no probs -, i think someone has even returned it rooted and been ok. These things are fairly bulletproof, and really hard to 'brick'. As long as you can read, follow a few steps you shouldnt have any probs. The worse thing you can do is try 2 or 3 different methods all at once because something isnt working right. You're best to pick one and stick with it, if you have probs ask for help in the thread you got the rom from or start your own like you have here
3) The update.zip method from the first link you posted "should" work. Did you "decrypt" the file you downloaded before extracting the update.zip??
You could try timmyDeans v4 method- it will install a stock 3.2.1, it is rooted but you can remove root using the tools he provides. Beware though this will wipe all data so backup anything essential.
The update.zip method will leave your data and settings intact
As always the choice is yours, there are some really excellent custom roms out there - I enjoy the best of both worlds with a backup of my trusty stock 3.2.1, I flash to my hearts content knowing I can always go back to it when the OTA update is out!!! Oh the joys of root priveleges
Thanks for your input, I'll make sure to try all this when I get back from work. I've a few additional questions:
1) If I install a custom rom, will the OTA work from this ROM or, comes the OTA, will I have to restore my actual Stock rom and then proceed with the OTA?
2) I haven't tried the rom on the first link I gave because it is modified and I was searching for the original, pristine, untouched stock ROM for 3.2.1
I've seen such roms around here on xda for 3.2 but none for 3.2.1, if anyone stumbles upon one please let me know.
3) Since I'm still looking for a pristine ROM before trying anything else, I have a friend whose tablet (same brand and model) safely updated to 3.2.1, is there a way to make a rom from is gear? If yes, how to?
4) (related to 3) how can I backup my actual ROM, do I have to be a root user to do so?
THX again!

4) (related to 3) how can I backup my actual ROM, do I have to be a root user to do so?
THX again!

1. Typically, most people do not take OTA's when running a custom rom, as basically the OTA installs a totally fresh factory Rom. This is true with the 3.2.1 update, which contains a new bootloader. Usually, this means you lose root, and Recovery, then stuck with downgrading to get these things back.
Timmy Deans root tool supposedly maintains a back door method, which s supposed to protect root, in case of an OTA. No, I haven't used this method, as I run my own 501 roms.
2. Vache has a thread "full package and updates" in the 500 Dev forum. There are several factory Roms and Updates. You'll have to look. Chances are, he may not have the specific Com Gen version you want, but probably one close enough.
3. If your friend can get adb running, you can pull a "system dump", which will dump all files/folders in the system folder. The boot.img would be nice to get, but you can probably use the current one you have. Unfortunately, he already rebooted, so you probably can't get the original full update file. If he's rooted, you can use an app called Rom Factory, to get most of what you need. It's always a good time to become familiar with ADB.
4. Well, you can back it up internally, but it's sort of useless if you can't get into your OS You will need to Root, and install a custom recovery to keep your backup externally.

ok, as Moscow has pointed out, in vaches thread not all roms are listed. My stock roms (1.016.01 and 1.139.04) for instance weren't - so I spent the last hour or two trying the "EUU gen1" listed at the bottom of the page. Well, it actually worked!! It gave me an OTA to 1.139.04 straight away. After that installed i got the 4.010.40 to 3.2 and then the next 2 for 3.2.1 - 7.006.03 and 7.014.15. So its given me the correct updates for my country AND kept my data and settings too.
SO, since you're on a Gen1 Rom this should work for you too, but still no gaurantee you will get the OTA to 3.2.1, no harm in trying though
btw timmydeans method is a gen2 rom so you can rule that out...
---------- Post added at 11:25 PM ---------- Previous post was at 11:16 PM ----------
just came across this link for an update to stock 3.2.1 build 7.014.14 here - orignal thread here but you need cwm to install it....
unless you can make it into an update.zip???
but thats way outta my league,
moscow may be able to suggest something though
Thank you very much, your answers help a lot! Just a few precisions and I'll stop being a pain in the ass!

==> @ Moscow, when you say "lose recovery" does it mean I lose the green thingy with gears when I start with volume down and power pressed/ and when I reset to factory settings?
==> @dibb_nz your method is the closest to what I'm looking for, I also hope it will give me the correct updates for my country and since Vache is a fellow countryman it might just be ok.
Anyways thanks again, I'll give a thorough look to all of your solutions and try and do a few things tomorrow afternoon. I'll keep you posted in case this thread interests anyone else.

No, what I meant to say, is when you run a rooted "custom" Rom, and use a "custom" recovery such as RA Recovery or CWM, getting an OTA update, usually wipes that out, and installs the factory bootloader. Your factory recovery....cough cough.... will still be there.
If you are only concerned about stock factory, then don't worry about it. You;re ok. Your factory/stock recovery will be just fine
The reason we root and install custom recoveries, is so we can do 3 primary things.
1. Flash a custom rom
2. Create a complete system backup to our external SD card.
3. Get rid of pre-installed useless apps.
There are other things we can do with it, but these are the primary reasons.
When you have a default factory stock system, the only protection you have, is a factory reset (hope it works), and a couple other methods which require a touch more knowledge.
Anyhow, don't worry about your factory recovery. It's just fine.
1) Just for the sake of knowledge what's the difference between GEN_1 and GEN_2? (and GEN3 and CUS7 and EMEA_TMLP)?
2) @Dibb_nz when you tried with the stock rom from Vache, was it because you encountered the same no FOTA update problem as I did? Or just to try...?
3) Something's still unclear to me after browsing through the forums: If I get an unmodified stock ROM can I flash it with the stock recovery? (so without rooting) Or do I need CWM (so root is needed)
4) What's EUU? (on Vache's thread some roms are listed as EUU)

1. The Gen's usually signify regional based roms. More specifically language support, sometimes a wifi tweak, and maybe a couple other things. Mostly though, ComGen1's are for the US and probably canada, and offer about 12 different languages. TMPL is for East Europe mostly, with polish as the default language. All roms contain the english language as far as I know.
3. You basically can't install a full rom on an unrooted tablet without CWM or RA Recovery. You will have to run the update (decrypt the file, remove the update.zip)
4. EUU is a pc based install. Plug in the USB, set your tab to APX mode and run the EUU.
If you did the root, and install a custom recovery, then you could run just about all the full roms. Your custom recovery would be overwritten, and you would lose root access. You would have a stock tablet with the version rom you selected.
You can always wait a week or so. Am sure if the update has been pushed to your country, it's just a matter of time till you get it. It's common for the update process for specific roms, to get fully done in 2-3 weeks. It took well over a week just for users in california to mostly start getting updates.
Well the official release date for the ICS FOTA in France is May 3rd, so I'll wait until then but having other options and the know-how to take actions is always a good basis. (plus I'm really not the patient type ^^)
Stupid question but I'm guessing EUU needs root too?
and also APX means rebooting while holding power and volume - right?

I tried the EUU just to see if it would keep me on my regions OTA upgrade path.
Sometimes you can have probs OTA'ing if you aren't using the rom from your region.
But in this case it gave me the correct OTA's.
APX is Acer Download mode, where the OTA upgrades are flashed - this EUU will do it via your PC. Button push method (power/reset button) not required.
No, the EUU does not need root which is why I tried it out for you
You will need to be on 3.2.1 before you will receive the ICS update
I used this EUU from vaches thread -
EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
late for work will check back later
That's really helpful thanks I'm downloading the same EUU you used and will try it today or tomorrow depending on how much time I have, will keep you posted!
Ok so I did the EUU install and it worked fine, the tablet then allowed me to upgrade to 3.01 and then 3.1 then 3.2 via FOTA without any problem. But once I reached 3.2, the update tool informs me that there's no update available and my gear is up to date
So my guess is Acer France are not pushing the 3.2.1 FOTA update anymore...
Any other explanation?

Glad to hear u got thru the EUU process OK, not so great u still can't ota to 3.2.1
Others have reported similar issues not sure if/how they were ever resolved. As moscow posted earlier,ota,s are not made available to all users in all regions, all at once, so it may be just a matter of waiting for the next "push cycle" to roll round.
At least you know you can always get back to stock if you ever decide to root and go custom There no direct root method for 3.2, just use that same euu to get back to 3.1 and use iconia root and Acer recovery installer from the market and you're ready to flash your rom of choice
Pls post back if u do get the ota - best of luck
rgds Donna
Yeah I was just browsing the XDA forums, contemplating the idea to rollback and root and then installing this
I wonder if it's worth waiting for the OTA... as for what you said about waiting for the next "push cycle" I've been waiting since I got the tablet and the update hasn't come yet, which is strange because the ICS update is due on May 3rd in France and I'd guess they'd have everyone up to date and ready for the update by now!
Rooting seems pretty straightforward and much easier than what it was on my Samsung Galaxy Spica: I found this
, a file called iconiaroot.apk on the sdcard aswell, rebooting your tablet while pushing the volume down button so its starts flashing the buggy honeycomb version.
Then start up the tablet again, rush to the market, download some file manager, with that filemanager explore your sdcard, and install the iconiaroot.apk file, once thats done, rush back to the market and download and install acer recovery installer. At that point you will have CWM (clockworkmod) installed.

is that all there is to it?
In any case I'll keep you posted just so it can help anyone with the same issue!
alsoe FYI and just for the anecdote: the reason I'm so cautious about everything and scared ****less of rooting is that the tablet is a present from my girlfriend for my 30th birthday, and she'll hang me with my guts if I brick it.
Ok I rooted and flashed the above-mentioned rom and it works! I'm now under 3.2.1!
Thanks to everyone who helped me! When the ICS update comes I will post here to signal how the FOTA went.
Thanks again!
Lol, good onya for taking the plunge! Yeh acer recovery installer is brilliant, along with iconia root, makes the whole process stress free.
Will be interesting to see if you get a notification for ICS OTA with that rom.
Can always flash one of the leaks if u get impatient??
Glad everything's worked out and yr g/f still talking 2 u
rgds Donna
thx! I will post here when/if I get the OTA. and my love life is safe thanksnto iconia root
okay so the ota has been rolling for over a week and a half now and still nothing for me

Oh that would be awesome! Are you rooted? Let me find the commands in the meantime, I read somewhere it's a simple one command in terminal to extract the recovery partition into a file on sd card...
WHAT AN ORDEAL !!!!
But in the end: SUCCESS!
I managed to get my tab updated with the Verizon OTA update.
The problem is definitely CWM !!! A rude awakening is in store for everyone with the P6800 CWM installed, because it a) fails to verify the checksum of OTA files correctly on the i815, b) it thinks the tablet is a P6800, so the OTA file fails to run if it assert checks for "SCH-i815" hardware AND lastly c) modem updates don't work because the device /dev/cdma_update doesn't exist, so the modem.bin firmware_update call fails !!!
In short, I had to fumble the OTA file apart and do the update manually in two runs:
First file, kick the checksum, hardware check and modem update out, then manually run the ZIP through CWM. The zip subsequently (LUCKILY) updated the stock recovery and overwrote CWM with a new fresh stock recovery.
Second file had everything kicked out BUT the modem udpate and LTE patch, so with the STOCK recovery this file ran through just fine, updated the modem and then applied the LTE delta patch.
Phew!!!
Of course I had to manually restore root after the update, had backed up with voodoo, auto restore failed, so terminal and hacking it was...
Now I have the tab running on clean stock FD01, baseband and LTE FD01, rooted and stock recovery.
No more CWM, no more "hacking" with the ROM until some dev finally releases a "correct" CWM and at least ANY factory ODIN image is available to bring the tab back to stock if needed!!!
Kinda sick of the non-support for this tab. So much going on for the Galaxy Note and pretty much every other device. I'm starting to regret having bought this "special" Verizon version
Awesome find and great to know for whenever ics does come out. Could you please post the recovery img you got?

OK after getting so many responses I decided to just post everything here in hopes that it will help others, too:
All files are here:
http://www.mywo.org:88/XDA/sch-i815/index.php
Step by step procedure to update the Verizon Tab from ..FA02 to ..FD01 build IF YOU ARE stuck with CWM installed on your tab and the original OTA fails with errors:
Upload the SCH-I815_FA02c_To_FD01.1.zip to the INTERNAL(!) SD card. This is important because CWM contains a bug that will only allow you to install from ZIPs stored on the INTERNAL SD storage.
Upload the SCH-I815_FA02c_To_FD01.2.zip to the EXTERNAL(!) (micro SD) card. This is important, because after the factory recovery is restored, it will correctly (and only) look for ZIPs on the EXTERNAL card.
Best way just copy both files to both locations
Fire up CWM and do "install from ZIP" and select SCH-I815_FA02c_To_FD01.1.zip
It should run (takes a while) and eventually tell you all is done. BOOT the tab. It should boot fine but in system it will show the new Android build FD01 but the baseband (radio) will still be the "old" one.
Now press and hold power and vol up again until you see the default Samsung recovery menu. Choose install from ZIP and select SCH-I815_FA02c_To_FD01.2.zip. This will now upgrade the baseband only. When done, reboot and enjoy being back on the "factory upgrade path" with the tab.
I hope someone more savvy than me can "fix" CWM to work properly with VZW tabs (accept the checksum, not fail the check for "SCH-i815" and provide the correct /dev file links for radio upgrades). Until then, I recommend just leaving the tab as-is and not tinkering with the ROM. Not that there is any custom ROM available anyway :-(
I also pulled the NEW factory recovery image FD01_recovery.img with the following command:
dd if=/dev/block/mmcblk0p6 of=/sdcard/FD01_recovery.img bs=4096
So in case anyone with a botched recovery wants to restore factory (Samsung 3e) recovery. This was actually the reason I had to go through all this... There is NO factory recovery image ANYWHERE to be found. I can't believe that I should be the first one ever to post one?? Anyway, hope it will help
I'm still quite new here, so I do really appreciate every click on that "thanks" button
P.S. for tinkerers and devs I also uploaded the original, untouched OTA file (0559c0e4e08e.update_SCH-I815_FA02c_To_FD01.bin) as it came from Samsung or Verizon or whatever and ended up in the /cache partition.
THANK YOU!
Electron,
You sir, are a BOSS! Thank you so very much for doing the work, and sharing it. You just made things one hell of a lot easier on me, and anyone else that follows.
Regards,
-Rob
Also want to say thanks. You rock, dude. I wouldn't have known how to revert **** on my own.
Also, I feel like we need a sticky or something for sch-i815 owners to go to for device specific stuffs, especially since there is little knowledge/info out for this device.

You're in luck! You don't need to go through the whole ordeal because you do NOT have CWM! You can just update the regular intended way. Go into settings, about phone and then click check for system updates. If it presents you the OTA update, just do it the regular way.
My complicated "hack" is only necessary if you DO HAVE CWM installed.
Im sorry I did not explain well what my issue is.
I do not have CWM installed, however i did delete a few appilcations using titanium backup. This causes updates to not take. I would really like to just take it back to factory and start over (this time with less stupidity on my part)
I of course would assume that once its at factory i can then install updates again.
Right now when i try i get the "!" droid sign and a reboot

Hey
OK unless someone can tell us how to "make" an ODIN flashable ROM for you, here is what I would do (and please don't get scared because it sounds a bit convoluted).
First, you need to be rooted. This is obviously the case.
IMPORTANT since you don't have CWM installed yet, SAVE your factory restore.img before proceeding, this saves you a lot of hassle later!
Open the android terminal, type su (accept the prompt) and then type (or copy/paste)
dd if=/dev/block/mmcblk0p6 of=/mnt/sdcard/factory_recovery.img bs=4096
Check that you have a "factory_recovery.img" file on your sd card now it should be about 8M big.
Now you're safe to install CWM from the forum, look for the other thread(s) where this is being discussed and follow the instructions for the P6800 "international" version with 3G. CWM Thread here:
http://forum.xda-developers.com/showthread.php?t=1613638&highlight=cwm&page=3
Then (thanks to nicduim!) there is a full factory (rooted) CWM image floating around on the forums here:
http://forum.xda-developers.com/showthread.php?t=1613638&page=6
Which I used to restore my tab to "almost factory" with the missing bloat apps back in place.
I have a copy on my server here: http://ww.mywo.org:88/XDA/sch-i815/ it's the "2012-05-06.22.48.58.ZIP"
unzip that and put the contents on your INTERNAL SD card in the folder clockwordmod. So on your internal SD you should have /clockworkmod/2012-05-06.22.48.58 and inside there the files boot.img, recovery.img etc.
Use CWM recovery to restore this backup. If you never used CWM before. Press power button and volume up and hold both until you see the menu screen with text. You can go up/down with the volume buttons (go slow, it's very laggy) and with the power button you "select" an option. Select the "restore from backup" option and point it to the only folder being offered, the 2012-05-06.22.48.58.
The restore takes a while, then reboot the tab. Now you're back to stock! Last thing you need to do is get rid of CWM again because in the end it's still a bit buggy and will prevent the OTA update from running properly.
Since you luckily have a backup of the factory recovery in form of that factory_recovery.img file, just install and open terminal again, type su and then type (or copy)
dd if=/mnt/sdcard/factory_recovery.img of=/dev/block/mmcblk0p6 bs=4096
This overwrites CWM with your original Samsung Android recovery.
Now you just reboot as usual, connect to the internet and wait until the popup message shows up that a system update is ready, accept it and enjoy
If you don't want to wait for the automatic OTA, you can also stop before killing CWM and use my convoluted 2-step manual update which will get you to the exact same condition as the official OTA.
Hope all this makes sense
I was already on stock FD01 when I tried installing CWM for the P6800 that's floating around here somewhere. Odin said it was a success, but it looks like it didn't take. I've done it a few times, but still ended up w/ the stock recovery. However, after reading through your thread, I do not see a /dev/cdma_update in my I815 either. Is it possible that my attempt to install CWM (although unsuccessful) wiped out this file, among others?
Right now, I'm still at stock FD01 (rooted) and everything seems to be working. When I tried doing an OTA update, it just tells me that I have the latest update and no newer update is available.
One other thing, if I have to, I only have the stock recovery right now since CWM didn't take, can I simply flash both zip's using the Samsung stock recovery to put everything back in stock?

Oh wait, so you are saying that in "About device" your Android is 3.2
Baseband i815.04 V.FD01 I815FD01
and your Build number is already at HTJ85B.I815FD01.SCH-I815.I815FD01 ?
That would mean you are already updated. In this case, it should be pretty easy to fix your problem. Which apps did you delete with Titanium? I can back them up from my system and make them available for you. All you'd need to do is drop the backup files into your Titanium backups folder and then fire up titanium and restore them!
The /dev/cdma_update node is only required WITHIN CWM recovery, so that is nothing for you to worry about. The zip files above won't help you because they are incremental updates requiring your system to be at FA02, not FD01 !
Yes... I'm already in the latest update. I already backed up the bloatware using Titanium Backup before uninstalling. So I just need to restore them back in order to receive and apply OTA updates in the future?

Please Help
Hi. I'm rooted and removed all sorts of bloatware with Titanium. I did this a long time ago and did not back anything up because I'm used to running hardware with custom ROMs available, and not relying on OTA updates.
Since there aren't any custom ROMs for the i815, I'd like to get ready for the upcoming ICS update. To do so, I want to get FD01 loaded onto my device, but I can't update because I've apparently removed too much of the required bloatware.
Does anyone know WHAT pieces of bloatware I'd need to reinstall in order for the OTA update to apply? I'd assume I can restore them and then apply the update and re-root.
If anyone can help pinpoint what missing APKs might help, I'll give them a shot. And, to the extent I figure anything out, I'll repost here in the hopes that it helps someone else.
electron,
Your instructions worked ... thank you so much
@jkrell... the failed attempt at installing the update should return an error message(s). You just have to read through them until you find the culprit(s). Apparently I uninstalled a few odexed files that were needed. I couldn't update until i hunted them down and restored them.
I guess we all jumped at the opportunity to install the cwm recovery image, that we didn't even think about cmda updates....ooops. So far i had to do a complete factory restore after the update. I was getting soft bricked to the point where I had no choice. Good thing I sent all titanium backups to actual sd card, i was able to salvage 97% f my data..... with the exception of a few downloads i forgot to move.
Gamecih doesn't work anymore (either version). No more automative data hacks I'm not sure what's going on. I uninstalled adfree..used titanium backup to uninstall both versions and reinstalled both several times. Oh well.
It really sucks not having nandroid backups but it's not worth the trouble of having to do this everytime an OTA modem update gets pushed to my tab. Needless to say, I won't be odining the cwm based recovery image again.
I'm with the O.P. I wish i hadn't wasted my money on this tab. No true cwm for this tab, so no dev will ever waste thier time with this tab. The sch i815 will soon be forgotten about and some other tablet will be all the hype before summer ends....that's just how it is. 21 months left on my contract.... [email protected]#k my life. Lol
Thanks Smitty.
When I try to update, I just see the "!" logo and then the device reboots. Is there a log file somewhere I can look at to see what the errors are?
I hear ya on the gloom and doom, but this device has only been out for just over 3 months now. I'd expect a recovery and some custom ROMs to come eventually. I doubt I'll go the custom ROM route unless CyanogenMod is supported, because I have no complaints about the tablet's performance thus far. It's speedy, smooth and the battery lasts forever.
In my book, this is a great tablet and I'm satisfied with the purchase.

Going crazy! Want ICS, haven't used tablet in long time.

Hi All,
I'm in a bit of a unique pickle. I have a Lenovo ThinkPad Tablet 1838-CTO, it is a US 32GB wifi-only tablet with all stock hardware (with disconnected keyboard folio).
I am running build number ThinkPadTablet_A310_02_0037_0075_US
It is not liking to play more than 5 minutes of a video before saying video cannot be played, video it played fine before. Tried all the standard steps, recopying, rebooting, etc etc. The device also sporadically reboots 20-30 minutes into use, sometimes. I have root, rootprotector, and I have CWR. I have not used my tablet since about a week after the first update from my current version above: my device went loopy, THEN the update failed, and I stuck it in a closet, $%^@%$*&@ed off at it for not working.
I want to either (depending on difficulty, and recommendations here) update my device to the latest Lenovo ICS *OR* Run a custom JB ROM (perhaps http://forum.xda-developers.com/showthread.php?t=1778375 though it is for ROW not US, unsure if that matters). Priority on maintaining root access, could care less about what recovery is used, etc.
OTA updates are failing since I had to get CWR , and I am not sure how to use CWR to manually patch/update.
As for the glitching and all that, I am fairly certain it has something to do with when I rooted it, I was a very early adopter of the first permaroot (I place no blame except myself for any and all issues, and muchly appreciate the efforts of others in allowing me to root my device, whether it bricks it or makes it 10x better). I just want to update my device to ICS and start using it again. I have done some searching but am finding that almost everyone is using 0089 or later with the same issue I have, trying to get back to stock bootloader. Honestly I would like to get it on Lenovo ICS, maintain root, and go from there.
I appreciate any and all advice, it's a personal device so I am fairly lenient on what I am willing to try.
Update: I would most appreciate a stock Lenovo ICS dump flashable from CWR if someone knows where to get one, again though any help at all is appreciated.
Update 2: CWM 5.5.0.4 unable to mount the SD card (/sdcard - not even sure if it is trying to mount internal or external, I have ALWAYS had nothing but issues with the external ALWAYS being write-protected no matter the position of the physical slider switch, though it always reads fine - Sandisk 32GB micro-SDHC with Sandisk MicroSD to SD adaptor), so flashing anything from CWM is a no-go. I want to take this thing and send it on a flying ride out the window, the only thing stopping me is it would probably survive just fine to spite and mock me. Sorry about being long winded, rather give you guys as much as possible info.
Is rooting the tablet all you've done? Did you remove any stock apps? I had the same problem with my TPT when I tried upgrading to ICS(from build 0089_US on wifi only 16GB)but only because I had a corrupt busybox file or something. Try going back to complete stock(NO recovery no root) and try to do an automatic OTA 2, then OTA 3. It should work.
How do I go back to stock recovery/bootloader? I rooted back when you had to swap in ClockworkMod Recovery, so my updates fail consistently when I have to reboot to apply, my guess is that the updater tries to pass calls to the lenovo bootloader that do not exist with CWR.
If there is a way to restore my bootloader then I should be all set, otherwise I think I need to find a good cooked rom
Get Some ICS

I posted an ICS Nandroid from a US 32GB TPT, exactly what you are looking for, here:

It will return you to stock Restore, losing CWM, but you can reinstall a proper CWM for ICS afterwards. See the Development Forum for the updated CWM version that works in ICS/OTA3.
You will have root, but you must download and use OTA Rootkeeper to bring Superuser back (don't forget to download and open SuperUser from Play store).
Good luck!

Going to try it tonight/tomorrow. Updating my Vivid to a non-corrupt CWR then flashing HolICS 1.3 from 0.9b tonight. Oh the adventures I get myself into... XD
Thanks for the upload, I'll let you know if(when) it works, either way I appreciate the effort!
