flashing back to stock rom. Update: Bricked?!?! Update 2: Unbricked :)

Hey all,
I've tried the various custom rooms out there and I'm looking to flash back to stock rom. Is there a tutorial how to do this. I also noted that when flashing between roms the files in the directory don't get wiped and are still there? Is there a way to flash to all original tf300t like the day I first bought it?
Thanks!

Ok I think I may have screwed up my transformer.
I remembered I made a backup using twrp recovery and tried to restore it (all the options were checked for the restore: boot, system, data, recovery).
After the reboot it gets hung up on the asus sign with the swirly circles. I can still get to recovery so I tried to flash back to one of the custom roms (aokp build 38) but it gets stuck in the loading screen as well. Arggg.
Any suggestions? Is it bricked?

Ok, I did a factory reset and that looks like it fixed the problem.
Now back to my original question, does anyone know how to load everything back to stock?

yes, I am interested in this as well. Backed up my first stock rom before I rooted, and then after I rooted, and am ready to start flashing but wanna take the proper precautions. Thanks for you guys help

i have the same issue... i flashed aokp, but as i tried to restore my stock rom, it freezes at the second asus sign...
but, when i restore, and do a factory reset like the op, i can see the android welcome screen, but when i select my language, he reboots...

for me this worked.
1. get the latest .30 firmware from the http://forum.xda-developers.com/showthread.php?t=1697227.
2. copy to the sd card.
3. reboot to recovery.
4. wipe
and then flash zip and wait.

Anyone know if I can do this through twrp?

I had to flash CWM over TWRP to go back to stock.......TWRP gave me an error repeatedly.

[Q] Nand restore results in bootloop

After flashing my first ROM on my new Asus TF300T I attempted to do a restore from CWM recovery and I just get bootloop. I have tried factory reset and wiping cache and dalvic but to no avail. The only way to get my tab working again is to flash back to AOKP. I have read the thread by d_crossfader but It doesn't seem to be the solution to get nand restore to work to get me back to stock. Please Help.

OK so I solved this. Sort of. Flashed a cyanogen rom and then was able to restore but then no wifi. I assume this is a kernel problem. Gonna try going to stock kernel. Can someone tell me how to backup the kernel? do I need TWRP recovery to do this? Is anyone working on an amon-ra style recovery?

Same here but solved it
I had the same problem.
i was on US.29 and wanted to upgrade to US.30 so i said before i upgrade lets try a custom rom so i tried 1) SKANKWICH CM9 KANG build and then 2) [AOKP][Build 40][4.0.4] Unofficial AOKP. I found that both builds was similar but didn't like (for my reasons) and wanted to stay as close to stock. So i tried to restore my 2 hours ago, nandoid backup. Bootloops was the result. Wiped data,factory reset,dalvik cache, and restored 5 times but no hope.
Solved this by installing the SKANKWICH CM9 KANG build from the recovery and when the device started, i downloaded the US.30 and unzipped it to internals storage root. Then restarted the tf300t in recovery,wiped data,factory reset and installed US.30 zip and everything now is fine.
I dont know if the reason is that before the first rom install i forgot to restore (copy paste) the original build.prop file.
Also finaly the machine was unlocked,unrooted without any custom recovery.

I think this is just a bug with nandroid restores, saw a few people having problems.

Good to hear! This is what worked for me too.
I then had to flash recovery again and re-root.
I used Thing O Doom's method because his tool claims to solve boot-loops and bricks as well so I figured it would be handy to keep around. Also, it is simple to use.
BE CAREFUL to insert the correct recovery blob if you use his tool though!!!
Here's the link to his thread:
http://forum.xda-developers.com/showthread.php?t=1681155

Will Try
I will try peri-04 one click root to see if i still get bootloops after nandroid restore. But where do u find the recovery blob u said u used for your Tf300?

Under "CUSTOM RECOVERY" section in the index thread:

After you get the blob file rename it to "recoveryblob" and replace the one that comes in the PERI folder.

Going from CM9 to stock ?

I have cm9 and want to go back to stock type roms.. less bugs..
anyway, how do I do this? I did a full wipe and restored hydro but the kernel stays on CM9 kernel.. and wifi wont turn on...

You need to flash the actual .30 zip from asus. That returns you to stock. Then do a custom recovery/root and THEN flash hydro.

Wow, that sucks..... thanks for the help tho. Think I'll just stick to cm9. I got it working well and its fast.

try hydro. Izs based on stock and is one of the fastest roms out there.

Which recovery do you have? Flash the latest twrp recovery and you can flash hydro without the need to return to stock. Simply download the newest base for hydro. You can also flash clean rom over cm9 without returning to stock. Make sure that you wipe cache, dalvic, factory data reset, and format system.

Switching from CM10.1 to Cromi-X, help me please :D

Hi guys, I have rooted and unlocked my TF700 few days ago. Currently with CWM recovery and CM10.1. I would like to change to Cromi-X for its faster performance. I am pretty new to this kind of stuff. From the Cromi-x TF700 developer page, it says TF700 user should be on stock 4.2.1. before flashing this ROM. Is there other way of doing it? What are the instructions to do so? Factory reset using custom recovery? install TWRP and bootloader? Step-by-Step instructions would be the best! Thank you so much! Would really appreciate it.:laugh::laugh:
FIY: I was on stock 4.2.1 before flashing CM10.1.

Thanks a lot for your swift reply LetMeKnow! Yea that was the forum I was talking about. Just that I am not quite sure about few things in the OP.
From the OP:
"STEP 2 TF700 ONLY – I have a custom recovery installed but not the latest bootloader
If you are currently unlocked and on a JB 4.1.1/10.4.4.25 based custom rom like CleanROM Inheritance 3.x and have a custom recovery installed:
I recommend you install the appropriate Bootloader Recovery package below as the safest route to upgrade to CROMi-X. This can be flashed from any custom recovery "
1) I am on 4.2.1, can I still proceed with the same method?
2) So I am supposed to flash TWRP and bootloader using the CWM recovery that I already have? Or should I use the fastboot command method? Just to make sure as I don't wanna brick my tablet.
Appreciate your help! :good::good::good:

I would love to help you further but I never use CWM. Therefore, it would be safe if someone has a better knowledge to help you out. _that, Sbdags, and others will have a good answer for you. They are very active in helping others users like you and me..

You can flash latest Cromix on top of CM10.1 even if you are using CWM (btw using CWM for CM roms is not mandatory,TWRP will work fine too).
I do recommend a clean install ( factory restore before flashing Cromi) but you could also try a "dirty" flash ( so your apps are not wiped) first and see if all works fine.
On a side note you should also try the CM10.2 experimental build,it's working nice here .

Thank you so much Pretoriano! Would carefully proceed to flash it tonight, hopefully nothing will go wrong. In your opinion, do you think Cromi-X has better performance(in terms of speed and smoothness) over CM? Because I still find lags and what not in CM10.1.

Not using Cromi-X so i can't tell but you should try different roms yourself, trust me on that.But don't expect miracles from any rom,this device it is what it is.sometimes works nice then at some point starts to lag,self-reboot and act like crap.Latest CM10.2 looks good so far but the best way to prove it is to install all your usual apps and use it for some time,then decide if it's a keeper.
As for Cromi-X or other roms,i don't know if Journaling is disabled by default,but if it is keep in mind that is just a workaroud which trade stability for performance.
Personally i've build a custom rom for myself based on Asus firmware,removed some bloatware,patched to have the advanced power menu,used some init.d scripts wich you can find here on XDA and honestly performs just fine,no dangerous tweaks applied or task manager.

You definitely should switch to TWRP recovery. It's working fine with both CM and stock based roms like CROMi-X, whereas there have been issues if you use CWM with stock based roms.
You do have to do a clean install if you go from CM to CROMi-X.

You always should do a nandroid backup of your old setup/rom before you flash anything new.
In TWRP 'Factory Reset' is the default selection under the 'Wipe' menu. It will wipe your /data partition except for your /data/media/ folder where your personal stuff lives.
Naturally, you should have a backup of all your stuff anyway!
Data nor backed up is data not yet lost
Edit: To literally answer your question: A clean install is wiping data and system partitions as well as cache and Dalvik. If you flash CROMi-X (and I believe that's true for most custom roms), the system partition will get formatted before the new rom installation as part of the installation process. Wiping Cache and Dalvik is the default when installing CROMi-X, so you don't need to do that either. Just factory reset before flashing and you'll be good.
If you want to go squeaky clean, you would do a format data in TWRP (under the Wipe > Advanced menu). But that will erase your entire data partition, so you definitely have to have everything you care about backed up.

That's a very clear explanation from you!:good::good: Certainly helps me a lot. One last question berndblb, can I flash TWRP over my current CWM directly(worry that it will cause or brick or whatsoever) before doing a factory reset? Or it is advisable to do a factory reset using CWM only then I flash the TWRP? Sorry if my question sounds dumb, because I am really new to all these stuff.

Your first step should be to replace the CWM recovery. A factory reset only affects your data partition - no need to do that in CWM.
The main thing is that you have at all times a compatible bootloader/recovery combination. If you have the 10.6.1.14.4 or 10.6.1.14.8 bootloader, you can download GooManager, tap the 3 dots in the upper right corner and select "Install Open Recovery Script". It will install the latest TWRP version 2.6 over CWM. I am not sure if your CM version is compatible with TWRP 2.6 - so better check on that.
But once you have TWRP installed, you can proceed as described earlier.
Your questions are absolutely fine. Read everything you can find 5 times, ask 3 times, flash once - if and when you're sure! :Good:
One more thing: If you decide you do a factory reset or format data in TWRP, make sure you have the rom you want to flash (and I highly recommend CROMi-X 4.7) on your external microSD - it's safer that way. You may have to navigate to your microSD in TWRP under the 'Install' menu. By default TWRP shows your internal SD. Just tap that field and navigate to your external, select the CROMi-X zip and flash it.
The microSD has to be FAT32. It you never changed the factory format, you're good.

You can flash twrp on top of cwm no probs. I do it all the time. CROMi-X does work fine on cwm 6.0.3.0+
You will 100% need to wipe data (factory wipe good enough) before flashing CROMi-X. Good luck.

Q1: I think you can just flash the new recovery via the current recovery if you have the new recover zip file.
Q2: Kat Kiss works fine for me.
Q3: If you want to completely return to stock, you would have to use NVFlash. There are tons of instructions on the Dev thread. I primarily use Tubuntu for flashing with NVFlash. [http://forum.xda-developers.com/showthread.php?t=1995157]
You can find other images as well. I used a stock image once to RMA the tablet but now I'm not sure where I got it. This method will ensure that every bit in your memory is exactly as it left the factory. Including the bootloader, recovery partition and everything else.
Q4: Refer Q3.

Download flashable TWRP 2.6.3.11 zip for TF101:
http://forum.xda-developers.com/devd...ct/dl/?id=3280
You should use TWRP for KatKiss ROMs, do not use CWM
Flash that Zip from CWM then reboot fully into your current ROM, then reboot into Recovery to check it has flashed properly
From TWRP you can wipe everything and flash KatKiss & Gapps

Yep, so long as you reboot into your ROM after flashing the new TWRP before booting back into recovery

Thanks for your reply, i will tray soon. So i want to clean the asus stock room to see if battery goes ok, i tried wipe data, cache, dalvik, with cwm, but nothing.
If i install twrp what more options can i try before change the rom? what more wipe do i need?? and finally, if i change the rom, is possible to go back to asus stock just flashing from recovery? or how should i do?

Apart from wiping the ROM (SYSTEM) there's not much else you can wipe, you could try wiping the same as you have already done, but from TWRP, see if that makes any difference, maybe the battery is coming to the end of its life
You can flash stock ASUS ROMs back again from TWRP yes, but you will wipe your recovery & ROM back to 100% stock by doing it
Best thing to do is to make a full Nandroid Backup from TWRP before flashing any custom ROMs, save it to MicroSD Card, then if you want to go back to the way it is now, just restore the backup from TWRP
That way you keep TWRP and can switch between as many ROMs as you like and always have your stock backup to go back to whenever you want

CACHE,
DALVIK CACHE,
