[Q] Wifi Xoom. How do I get back to original state?

I have a Wifi Xoom and I'm seriously thinking of returning it before my 14 days are up. It is rooted, and using the Tiamat kernel, and unlocked, how do i get this back to original way. What is the easiest way.
I really like the unit, but not to justify 600.00 with no source and no idea when source would be out. I find battery use ok, but not great, the apps are good, but i have a color nook and with NookieFroyo, and I find myself using the Nook more then Xoom. If there was Rom's etc, but at this time, we are kind of in holding pattern. Don't even know when the MicroSD will be on. Anyhow, what is the method to get everything back to normal.
Thanks

I received this in a pm this morning from stevenege, as I didn't want to root my wifi xoom until I could unroot it.
It is not un-rootable nor re-lockable as of right now, the files have not been released yet for the public. 3G yes, WiFi no :-(.
It will come though, and everything will be awesome.

Right, so how do i return this? I dont think any store would notice it, but i just will a factory reset and clean everything off it? I only rooted so i could use Adfree and Titanium Backup.

Yes, factory reset, return.

You can unroot it, but you can't re-oem-lock it.
If you flash the wifi system.img and boot.img found elsewhere, it will be back in a freshly unlocked but not-rooted state.

I returned my xoom to staples because i tested a theme and bricked it. it was still rooted and they didn't ask. they just wanted my order number so they can exchange. same process with a return. they aren't going to run test to check if it is rooted. just factory and return.

Question about my new Xoom updating....or not updating to 4.0.4

I just got my Xoom yesterday, and obviously brand new to it, and Android.
100% stock, and it's staying that way.
Charged it up first, turned it on, set up the wifi and all the normal setup stuff it has you go through. Checked settings and it said the version was 4.0.3, so I told it to check for updates, which it did, and it said 4.0.4 was available, so I told it to get it. It downloaded it, and something came up on the screen about installing and restarting, which I did. Screen went black for a bit, then it said something about booting into Android recovery, then went dark again....then I think the next thing that happened was there was a little Android robot on the screen, and then it switched to another view of that robot, kind of laying on it's side, with like an access door open on it's back, and there was a red triangle with an exclamation point in it. It stayed like that for a bit, black again, and then it rebooted, and seemed normal. But, it still says it's 4.0.3, and if I tell it to check for updates, it says I have the current version.
Did something go wrong? Did I do something wrong? . It seems odd it said it found 4.0.4 and installed it, and it still says 4.0.3
I even tried this manual method or forcing 4.0.4:
1. go to setting / apps then hit the all button at the top
2. scroll down to google services framework and then press it to open
3. hit the clear data button
4. go to settings / about phone / system updates (you will notice the date will be 1969 or 1970 this is ok )
5. hit the check now button
6. xoom should show you the 4.0.4 update avalaible
7. hit install and enjoy
no luck with this either.....have done it more than a half dozen times too.
FWIW, it is a U.S. version, and I do live in California, if any of that matters.
Any feedback greatly appreciated. Thanks in advance!

As far as I know, 4.0.4 update started rolling out in the US but it seemed not to be fully yet OK.
So you have 3 options.
1) wait for another OTA update. It might take a longer while.
2) root your xoom and flash custom rom ics 4.0.4.
3) live with 4.0.3
And by the way, custom rom is way way much better and robust than stock. I personally rooted my xoom the minute I unpacked it. Pretty easy.
Here on xda community, we ye d to help each other if you know what I mean. To start, we need to know your xoom type, wifi or 3g...

It's the Wifi version, and the person at Motorola said that 4.0.4 was out and available.
I'm not rooting it.
I tried that with a Kindle Fire with help form this forum, and it went south and got bricked beyond repair..........just not in the mood with a $350 tablet, no matter how easy it is.
I appreciate your reply though.

Hi, it is your call at the end of the day, although it is really straight forward and pretty easy to root your xoom mz604. Anyway, if you decide later on the road to do so, we are more than happy to help you, Xoomer

I'm in the same boat as you man... I get that red triangle all the time. I'm 100% stock too

Same issue: another thread here.

Yep, me too.....100% stock.
I sent the other one back to Amazon, got my second one today, and same thing, right out of the box. At first start up, right after setting up wifi, it says update available 4.0.4
It downloads and verifies it.
Press install and restart, it does that little robot animation for a few seconds, and right to the screen with the robot laying on his back with the red triangle with the exclamation point.
Motorola acts like they haven't heard of this much. Hah!
And the only thing they offer is to send a box to send it back to them, to flash it. Yeah, I want to send in my 3 hour old device that has an issue right out of the box!

It's not that I'm not thinking of it, it's just that I tried all that with a Kindle Fire with help from people here, and it went completely south, mainly due to a computer crash right in the middle of it. Long story short, I'm going to try it again on the KF, but I bought this because it's more of what I would essentially turn the KF into, and it's more money. I got a good deal on the KF, so I took the risk, I know it's not that hard, I just had a bad experience that left me with a bad taste in my mouth over the whole thing. I'll try the Kindle Fire first, not this.
On that note, I'm assuming there is a good guide to follow for rooting and/or flashing the Xoom, yes?

[Q] Error during boot-up after firmware upgrade: "No certificate to inject".

[Q] Error during boot-up after firmware upgrade: "No certificate to inject".
I updated my firmware to V10.4.2.17 WW manually. My tablet is not rooted or unlocked. The first thing I noticed was that my Transformer 300T now gives some sort of error message in the upper left corner (below the power button) during boot-up, the message is "No certificate to inject". It happens at every boot-up and doesn't seem to give any problems, but I'm curious if other people get it. Also I'm curious what it means exactly.
Any ideas?

Same issue here. I also cannot unlock bootloader or update vía OTA.

Help me too No certificate to inject, a new tablet

Same here, thanks for helping...
Same here:
I waited 2 weeks to see if I was getting it via OTA, ...but nothing, ...not even when manually asking for it via Settings -> Firmware update.
So I decided to go the manual way via the Micro SD card; all went fine BUT, now I have for 5 seconds, every time I boot, the same message:
No certificate to inject
Why ?
Thanks for your help !

Id like to add that I have the same issue with my new tf300t. Only did an update because I wanted to have the latest firmware but I kinda regret it. Has anyone found a solution?

Same problem
I have the US version and mine is brand new. The firmware update which was pushed to my tab VIA OTA has rendered it completely useless. I get the error, " no certificate to inject" and it does nothing but crash. If it goes to sleep or if I hit the power button to turn the screen off it will not wake up and I have to long press the power button to reboot. I can't even use it, it's basically a paper weight now. Does anyone have a clue how I can fix this? Should I try to flash the old firmware? If so can someone point me to a link on how to go about it.
I called Asus and they did not want to walk me through flashing firmware. They want to set up an RMA.
I've tried a cold boot, factory reset and data wipe.

Wow that really sucks. If its a paper weight and they offered to do an RMA why wouldnt you? Im still waiting on ASUS to reply to my email! lol. Look it's brand new and its basically a brick. Unless they can give you a solution thats easy i would just go through the return process.
edit: they emailed back saying that doesnt sound right and to do a factory reset. While i knew that wouldnt fix it i did it anyhow since i didn't have much data to lose. Long story short they want to RMA mine as well. Ugh.

RMA
So yep I sent it in for RMA, Very disappointing that and update did this to my brand new tab.

same here, dont feel so bad. It sucks.

So I got it back today from RMA and guess what? On the very first start up it still says no certificate to inject. Unreal, why didn't they correct this? It seems like the only thing they did was flash the old firmware back. Now my tablet is asking me to update and I don't want to because the last time it turned it into a pile of crap.

They want me to RMA it again. I wish I never bought this thing. It seems to be working fine, but I have a bad feeling about letting it do the firmware update.
Why didn't they fully update it when they had it? Also are they blind? It's completely obvious the error message is still there during boot up and I was very specific about it.

apparently they ARE blind. The message is quite easy to see when you turn it on. To be honest i wish i never did the firmware update when i first got it for Xmas. Thats when this all started for me. I'll let you know what happens with mine so you can either hate me or feel a little better knowing my predicament.

HAHAHA, I hope your doesn't have the error. Now I don't want to do the firmware update, because I know what happened last time. But on the other hand what am I supposed to do, never update my tablet ever again?
Would I even be able to skip the firmware update but still take any OS update they may push in the future?
The RMA is good for 30 days so I think I'm going to see what happens. It seems perfectly fine right now, no issues with it not waking back up.

Ok little update, it still has the error message, but is working very well. It's reading my SD card (which it didn't before) and no issues with it waking back up. I also ran the update and all seems fine. I'm going to mess around with it for the next few days and see if misbehaves. If it works perfectly fine and still has the message then so be it, I'm not going to send it back in.

Well i got it back shockingly no error message anymore but i also notice it wasn't factory restored. No problem i did that myself. Of course it downloaded the firmware update and wants to install which i chose NOT to. Not sure if and when i will decide to do it. lol. How annoying.

Well I ran the update, and it seems perfectly fine. I wish they had cleared up the error message, but I've been going at the thing all day and it seems perfect. They gave me a new RMA, but if it continues to run perfectly I'll just take that as a win.

I unfortunately am having the same problem..
I have gone through 2 tablets now at Best Buy.. The first one went from stock to .20 release and started getting the error.. So I get another one.
I figure that I'll be smart now and I have 2 other TF300's and the one that I had previoiusly all had no issues.. So I figure I will update to the previous release first..
Now I'm getting the message..
It did download the latest release but when it goes to install the OTA it fails.. EXTREMELY frustrating.. A TOTAL waste of my time.. I really want to kill myself right now.
Anyway... I'll manually update to the latest version and maybe pick a different Best buy..
I of course also put my Armor Shild on this one because I figured there was no way that I got two doing this in a row..
Yeah.. 40 bucks down the drain.. .I will call Asus and make some tech supports ears bleed tomorrow.. Yeah I know it's not his fault but.. well it's his fault.

Any new info on this?
Hello everyone, just got back into tech toys and having time to play around etc. Anyway got the same error after OTA update, also Keyboard spacebar does nothing anymore and the mouse pad doesn't work at all either. Looked online everywhere and figured if there was an answer for this it would be in these forums and haven't found one. Had to make a new account on here and haven't had the time to mess with anything in a while so it's all new to me again. Any help would be great, kinda scared to try anything after reading so many different ways to brick this thing- have an email in to asus, 3 acually, and no responses back on any of them and it's been months..thanks for any info - really want to unlock/root/recover and try some of these awesome looking ROMS but am stuck with this error and no response back from asus.

need some help with my tf101

Hey, I've been doing some digging and I need some help fixing my tf101. I've looked through a few threads and i'm not sure where to go next.
A few weeks ago I followed the instructions found here: http://forum.xda-developers.com/eee-pad-transformer/development/rom-t2942560[1][2][2] to upgrade my tablet with the katkiss rom.
To do this I found out that I have to install TWRP v2.8.1.1 so i did. Well heres where i'm kinda screwed; my tablets touch screen doesn't work in TWRP. I've tried using the volume buttons but they dont do anything. The only button that works is the power button which locks the screen.
The tablet gets into the build of kat kiss that I had installed previously (4.3) but I've got 0 apps installed. No store, no file browser no nothing which kills the idea of putting the APK files on the tablet to run.
I'm not sure what to do next to get this tablet up and running again, but I'm in a crunch for time and need to figure something out before Friday as I'm moving over the weekend and wont really have a lot of access to a computer to work on this with for about a month.
I've spent the last few days trying to figure this out and have more or less come up blank. Any help would be greatly appreciated!

I'm stupid. I fixed it. Followed instructions here: http://forum.xda-developers.com/showthread.php?t=1681155
You guys are the best!

[TF101] How to install KK/MM custom Roms from stock?

Hi all
My sister bought a TF101 years and years ago, and to my dismay kept using it despite it being stuck on 4.0.3 (ugh)
I finally stole it to flash MM katkiss, but.... I have no idea how. There are many old guides, many dead links, many versions of TWRP.
I'm asking for pointers on which guides to follow and which ones to avoid.
What's the best way to flash it?
I have OSX but I also have access to Linux and Win10 if needed.

I just got back into this forum , also. It looks like your only option for anything above a stock baseline is KatKiss. I have it on my tablet now, but I feel like the original OS is more refined. It just seems SLOW........ I have no idea why, but it takes forever for things to open, load, display, etc. It didn't act like this before I flashed it.
Years ago when I flashed this thing regularly, I know there was an issue with kernels. Tablets would go to deep sleep and not turn on, which required a hard shutdown and reboot. I don't know if that issue was resolved since I was flashing, but I am on the lookout for good software, also. I feel like I am just going to go back to full stock and just be happy for now. I doubt any devs are really active here anymore. I asked a few questions and have gotten nothing in return, also.
