[Q] root, flash & unroot: is it pssible? - Android Q&A, Help & Troubleshooting

good afternoon everybody!
I have a question: as I find a ROM that I'd like to try, is it possible to
root my device
flash the desired rom in it
and in the end unroot it back with the new rom on-board, to keep the system "closed"/ protected
if yes, does it make any sense?
thnx

New official folio update (2.2.5.0131) - flashing is NOT recommended for new users!

this official update will lock your recovery options to flash custom roms!
so my recommendations is
AVOID OFFICIAL UPDATES, and you're safe
Its still ROOT'able, but no documentation atm, for how to revert back to a recovery, that works.. but if you can root,
the important part is to copy my "recovery.img" file to a location on your device ie. like /data/recovery.img
and from shell you execute
cat /data/recovery.img >/dev/block/mmcblk0p7
root works
hello, i little speak english...
PdaNet + SuperOneClick method works for root
Sorry double post...
for rooter, you must do this if the update took place from Service Station:
1. Start the Recovery -> Wipe Data / Factory Reset -> Reboot
2. Start normal and remove Toshiba Service Station and Market Place -> Turn off the Folio
3. Start the Recovery -> Wipe Cache -> Reboot
4. Start with the normal and new rooter SuperOneclick 1.6.5. - Turn off the Folio
5. Normal Start

other reported that it did not work on new updates. only on old stock before 0053.. so maybe someone can confirm this on new release.
Maybe you can do a 'safe' version of the new ROM for us that doesn't include the new lockdown? This is so tedious of Toshiba - I struggle to understand what they try to achieve by doing this.
I'm starting to think Toshiba deliberately want's to make this device useless.
Do they hate there first tablet so much they even punishing the people who bought it?
This new releases works 100%
This new releases works 100% (PdaNet + SuperOneClick)

but can you flash a custom rom? its not much help if you need complex methods of installing / reverting back to another custom rom, so you recommendation might be users are stock on something they dont want..
AND!
users need to have a ADB connection to your folio, which again is not many regular users know how to do, so again making it much more complex to work with..
if will NOT RECOMMEND installing stock, for regular users.. you will spend hours on trying to get back to a custom rom, which is not needed at all.

Dexter, I'm confused. Or maybe I misunderstood. Why is it bad to flash to the new firmware when you can restore it back to factory settings? Coz once I can do that, I can get back my old firmware and flash custom mods again as before. Or would flashing to the new firmware make it the new default factory setting? Hmm....

This is such a bad move by Toshiba...at least make a proper product like Motorola then they can do these stupid stuffs
Oh no! I waited too long before ordering mine I've been told there's a new batch coming in March - obviously these will come with the new factory ROM!
Dexter, is there no way of putting on custom ROM's onto the device with this factory ROM pre-loaded?
That's part of the reason I ordered one - I like to tinker

seems it can be root'd after all, so its not all locked down, but i hope someone will write the "howto" for doing it, because its no so simple to revert it, but is possible..
Hello
How can I root it after this update? SuperOneClick doesn't do it.
What's 'PdaNet + SuperOneClick' method? What should one do to gain the root privileges?
One should find a SuperOneClick Tutoraial on XDA & follow it.
Works like a charm once you installed everything prior rooting procedure.

Quick question.

Hey guys.
Getting my GSII in a few days and my first task is too root & flash a new rom.
As the bootloader is unlocked on this, can I just flash CWM onto it, make a nandroid backup and install a new rom. In this case Hyperdroid. Will this work fine and then I can use superoneclick to root it.
I am coming from a Wildfire S so I am assuming there is a different way to do all this. Just want to see if I have the main concept correct
Best way is to read all the How to Threads!
IMHO the easiest way is to flash a CWM Kernel then nandroid then flash your ROM of choice.
Try these two threads to get you started.

Thanks for the help, I have knowledge in flashing etc, but coming from an entirely different phone I thought I would be safe and ask making sure I had the same idea of doing it.

[Q] A little Unrooting Doubts

Hi.
First of all, thank you for sharing SO MUCH information on this forum!
Now,
I got my Note last night and I rooted the it using dr.ketan's instructions (http://forum.xda-developers.com/show....php?t=1329360) with the method #1b... I only rooted it for using orbot and don't feel the need for a custom ROM at the moment. Thus I didn't see the need for following through anymore steps (2 onward). I did make a back EFS and backed up my apps and system settings using titanium after I rooted.
My question is, if I want to unroot, do I simply repeat the rooting process only with the following two files:
UnRoot :
Busybox uninstaller - Flash in recovery
Complete unroot (busybox+Superuser) - Flash in recovery
Click to expand...
Click to collapse
or must I find a stock ROM as described here and flash that over my already stock setup. Since I have no interest in custome ROMs/kernels should I worry about anything like bricking or corrupting my phone?

Since your already on a completely stock ROM setup just select the completely unroot option once it completes reboot the phone and you should be all set. If your returning your phone to the manufacturer or bringing it in for service then you would want to reflash the stock ROM just to be extra sure they could never tell you were rooted

[Q] Is this even possible?? (custom rom build, stock recovery and unrooting)

Hi guys,
I've been asked to look into the possibility of flashing some Android tablets so that they have some extra apps included.
We all know that you can build a rom from a stock one, add the apk files to /data/apps or /system/apps, sign, package it up and then flash. However I'm looking for a more complete solution.
I need to get these tablets to a point where once I'm done, when you turn in on you get the out of the box experience, all counters have been reset, device in NOT rooted, the recovery partition restored so that the device will pass a warranty inspection.
in my mind the to do list looks something like this;
root device
flash recovery
backup device (just in case...)
dump rom (as i might have a new model that a stock rom download doesn't exist for yet!)
edit rom to include the 2 extra apps i need to install
flash the new rom
revert recovery to stock
reset all counters
un-root device
anyone know of any reason why this wont work?
I'll be honest I have been playing for a day and I can root, flash recovery, (can't dump yet so used stock rom from dl), add apps to /data/apps but I keep failing on the flash.
I also know i can revert the recovery and unroot.
Anyone got any tips? or any nugget of information that proofs I can't do this so I'm wasting my time?
thanks in advance guys.

How to Backup or clone the whole system without root?

I wanted to make a backup of the stock ROM before rooting.
I did some research and found couple of solution with root and without but none of them are solid and specific.
Question:
How to backup stock ROM or make a clone and restore without any root or unlocking the boot loader?
Want specific answer and solution.
Thank you!
