How do i take the prime back to stock? (Stock kernel, ROM, and no cmw)
Thank you!
I'm no expert, but I've read a few threads that seem to indicate because ASUS hasn't released "NVFLASH" you will not be able to re-lock your device at this time.
It's a bummer, as I remember how easy it was to re-lock my A500, but it just makes you think a bit more before unlocking.

I dont mean relocking it, i mean unrooting it, removing CWM, and restoring the stock ROM.
I'd love to do this as well - anyone know how?
be careful with this, so far there is no way without hard bricking your tablet and there is no recovery for that. just keep checking the dev section until a real way to restore stock found.
Stock rom and kernel isn't the problem. There is already one up in the dev section. So far as I know though there isn't a way to get stock recovery back...

I could be mistaken but I beleive there is a thread in the dev section for .15 flashable completely stock rock. By jeremaine151

I've unlocked, rooted and encrypted my TF201. It's running the stock Asus ICS ROM (albeit unlocked and rooted). CWM is installed.
When I unlocked this device, I had no idea it was permanent, and frankly I recognize now that I really don't need an unlocked tablet.
I would like to sell my device now, so I would like to wipe it. Knowing I can never revert it back to an original factory "locked" state -- what is the best way to wipe all my data from this device and avoid bricking?
Many thanks!
As an aside, if anyone wants it, it's ~1 month old, in great shape, and I'll be asking $450 for it (NYC area).
*bump* anyone?

i believe you can just delete all your user information, and set it to default factory settings
and just reflash your rom it should be good to go for sale
Thanks for the reply. It looks from all the 'brick' posts that doing this incorrectly will result in permanent brickage. Which ROM were you suggesting I install, and exactly which wipe were you suggesting I use (cwm wipe or ics->settings)?

Use CWM wipe for sure. As for ROM, probably best with just the cwm-flashable stock .21 which is in the Dev section setting as you are selling it.

Thanks barryflanagan! Am assuming you're referring to VirtuousROM?
I have a quick question. Right now I am running the latest version of wookie rom. If I wanted to go back to Asus stock rom could I? Could I download the image from Asus website and use twrp to flash? I thought I read somewhere that I could brick my prime if I do that. If I can brick it, is their a safe way to go back to stock?
Thanks
Well if you are running a rom, i'm going to assume your unlocked.
If you unlocked then i suggest you get your NVflash backup files. Because as far as i know, that will make you unbrickable even from bootloader flashes.
As far as how to flash back i'm not sure, but I know there is a tutorial somewhere on XDA.

1) this is not a development topic and should not have been posted in the development section, this should have been posted in general, or q&a.
2) follow the thread on getting nvflash access, that way you are protected from bricking once it is done, it requires being done first, so do that now. you cannot get nvflash access from an already bricked unit.
3) as long as you have the above you should be fine to attempt flashing a stock asus update. The problem with stock asus updates is still rather unknown, some units will flash it fine, others will brick, we have some theories, but nothing solid until we can get someone with nvflash access to get into this situation.

Is there a way to root the tf201 running stock JB while keeping it's bootloader locked ?
I have tried running over all the threads here to find an answer and it seems to me that all methods to root the tablet requires flashing of a new boot loader..
Sent from my Transformer Prime TF201 using xda app-developers app
There is a serious aversion to searching on this board even a cursory browsing of all the forums would yield the answer because it is asked every day.
In short, NO, not without unlocking.
Thank you for the reply..
The main issue I have with unlocking the bootloader is that i will not be able to get future updates from asus.. Maybe there is a method to get rooted by unlocking and maintaining the original bootloader?
Really have to get rid of all the junk asus preinstalled on the device :\

Root and recovery are not really related..
If you are running the stock recovery you should be able to use ASUS apk to unlock it.. Then you can flash your custom recovery and change to whatever rom you like, just make sure you are flashing a JB ROM.
I am running the stock recovery and stock JB.
Every time I enter the input the info in the stock ASUS unlock apk it fails. I have read several places that it only works on ICS and that ASUS turned it off anyway. (although I haven't tried it in a week or so since everyone seems to think it doesn't work at all anymore; I will try it tonight)
Or is there a hacked ASUS apk that will unlock on JB and/or without talking to the ASUS server?

I unlocked mine on JB just a few days ago. The tool still works with JB (the notice on the site is outdated).
Some people have noticed that some primes (especially ones that have been repaired) don't want to unlock for some reason.
There is no way to unlock other than the official tool.

The reason the unlock fails is because the serial number is not showing up in ASUS DB to provide the unlock code. The unlocker communicates with ASUS to get an unlock key for each serial number and if your not in their DB well.... No unlock for you.
I did verify the sticker matches the digital serial number. I had hoped they would be different so I could update the digital one.
Anyone have a good contact at ASUS that would check/update their database?
The emails I have had with them so far have not been very helpful.
Edit:
I wonder if I change my digital serial number to one that someone else has already used to unlock will it send the unlock code for that serial number to me? And would it work? Or would I brick my Prime?

hello everybody,
I am new here though I've been wandering here for a while looking for advices. Do I need to introduce myself?
I finally decided to ask directly in a new topic hoping that this was not already asked (I looked a lot but nothing directly answered my question).
well as a student, I would like to use my university proxy wich uses a .pac file and the only app that allowed me to use .pac files needs root. Furthermore I'd really appretiate to have a ubuntu flash on my TF201 and this again seems to need root. I once tried to root my TF but it was like the first version of ICS. Since then it seems that I've completely lost root so I was wondering if it was possible to root JB even tough in the end my ICS was not rooted. I also wanted to try a downgrade so that I could root my ICS and then update and finally reroot my JB. But I didn't manage to find a way to downgrade a TF201.
If it has already been asked then my apologies but I really looked around maybe I should have looked more.
thank you very much

You can only root Jellybean if you are unlocked and have a recovery installed like TWRP but if you do that you might as well install a custom rom with root built in.
You cannot downgrade to ICS unless you did the nvflash process while on ICS and kept the files created during the process.
thanks for the answer, I will look for a custom rom though I didn't know I could flash a room with built-in root, that's good news if ever I manage to unlock my prime.
thanks again.

This is not quite true there is an alternative...
Android and Linux, having a similar heritage, makes it possible for us to get root access over the Android phone if you are running with root privileges within Linux.

Don't know how to get this to work, but i am working on it
If I knew a bit about unix programation I would gladly try to find a way to get root access by myself but that's not the case I'm just learning about HTML and java so I'm a long way from this knowledge. Anyway if anyone find something about this I'll take it. I looked for unlocking my bootloader but it seems quite dangerous (risk of bricking my device) since I don't have a way to backup.

I have no idea what he is quoting above but without unlocking you cannot root jellybean if you have Linux or not.

I cant remember reading about anybody bricking while unlocking. As far as I know the primary way to brick a prime is to install the wrong recovery for your bootloader. If you are on jellybean via an asus ota update you cant use CWM as your recovery and you can not install the TWRP that is meant for ICS. So unless you pay no attention its pretty hard to brick your prime.
So if neither TWRP nor CWM work as a recovery for my bootloader (I got an OTA jb update) can I still unlock my bootloader? Are these 2 things part of a same thing or are they different? (if the recovry tool doesn't come with the unlocking tool, is it necessary or just highly recomanded?) In fact if somone could explain me a bit more about that recovery tool maybe I would come to understand what I am sayingˆˆ.
Thank you very much!

What you can use after you unlock via the Asus unlock tool is twrp for jellybean. Once you have that you can install any ROM built for the jellybean bootloader

You misunderstood what whycali told you. Only the version of TWRP for ICS cannot be used if you are on JB Bootloader. TWRP version for JB is the way to go - the only way to go for you :good:.
In the end, I read that the unlock tool from asus normaly used for the ICS version could also work for JB is it true? And, if I unlock my tablet and install a recovery, then I will not be able to get an OTA update anymore, I will need to flash the next updates if I want them aint it? But then, are there any Roms stable enough worth unlocking my tablet? (If only I did root my device before... but in the same time it allowed me to know more about all this stuff).
I hope i don't bother you to much with this.

yes the unlock tool works on JB primes. stock ota roms from asus are not stable enough to be worth not unlocking your tablet. both the energy rom and the wookie rom are miles above anything asus will be sending out ota or otherwise. When there are updates the makers of custom roms rapidly incorporate them into the custom rom.

I'm curious about something regarding the newer ROMs in the dev forum. Why do so many of the newer ROMs coming out insist that you have to be on the JB OTA before flashing? I'm familiar with flashing on other phones where you just wipe and flash, and move on with life. Does this have to do with the radio/modem? And if that's the case, could you not just flash the ROM and then a modem? I'm just trying to get some clarification stemming from genuine confusion.
Not really sure but could it maybe have something to do with the trust/compatibility deal thing?? Idk I was wondering the same question in op. By no means is this the answer I was just throwing this out there. Hopefully someone can shed some light.

No, its the tz partition that is only changed throught the OTA/LGNSPTing that is needed. I'm not quite sure of all the specifics, but this tz partition is what you need to flash these new roms.
Excellent explanation, much thanks. Quick follow up question now... Once the OTA update is done, is that more or less permanent for the purposes of ROM flashing? In other words, does the phone have to be put back to stock every time I want to change ROMs?
Sent from my LG-E970 using xda app-developers app
You only need to do it would once. Once the tz is put in place it stays, unless you lgnpst to the n4 conversion or to ICS. Flashing a ROM in recovery won't change it.
Beautiful. That's what I figured, but better to ask before bricking my phone. Thanks again.

Standard "I'm not a developer but..." disclaimer here. You can either revert to the stock ICS build and get the OTA update, then re-root/unlock, or I seem to remember a flashable stock 4.1.2 zip file in the development section that is supposed to take care of the TZ stuff to let you move on with life.
Feel free to correct me if that's not good information, though.

That is my understanding. Once you have the TrustZone partition set up from the stock JB, it's there and you don't have to mess with it again. Unless you do something that kills it, like go back to an ICS rom.

Sweet. Thanks for the help. I'll post back if for some reason it does not work
Good question OP, I was wondering the same thing and this LGNPST thing is confusing.
So, I am currently running SnowJB (which I believe is 4.1.2?)
Do I need to do the LGPNST in order to install these newer ROMs, such as Vanilla Rootbox? Or am I all set to go ahead and flash new ROM?
To anyone confused, ask yourself...
Did you receive the 4.1.2 (JB) update over the air OR did you use lgnpst to flash to 4.1.2?
If yes, then you can begin flashing as usual without having to lgnpst every time you change ROMs.
If you haven't used one of these methods then you need to do one first before flashing the new ROMs.
Simple as that.
