[Q] [Answered] Questions before atempting to install CM - Transformer TF300T Q&A, Help & Troubleshooting

Hello xda-developers,
My TF300T was becoming very slow in the last few months so I decided to reset it to do a "fresh start". While doing so I would also like to upgrade my ROM. (Im currently running Android 4.1 with CleanRom 3.2).
I'm using the CWM Recovery 6.0.1.3 and would like to upgrade to CyanogenMod 10.2 (Stable - the *.zip file from the CM-website)
By reading several threads there seems to be some problems with current Android Versions and older bootloaders. My question is now:
Can I simply flash the new CM-zip with my recovery (After doing the factory reset) - or is there anything else I have to watch out for?
Thanks for your help in advance!

If you are on a 4.1 ROM you probably need to upgrade your bootloader first.
The easiest way is to flash the latest ASUS stock ROM, then do a factory reset and after that flash recovery and your new ROM.
There are several ways to accomplish this, all covered in detail in several threads.

When you upgrade your bootloader, you will need to upgrade your recovery as well to a -42 TWRP if you are flashing CM10.2 or TWRP 2.6.3.1 for KitKat.

Alright, get Asus Stock from their website, install that, then reset and flash recovery (TWRP - what exactly does the "-42" mean?) After that I'm good to install CM.
Okay, I think I understood - thanks!

Oops, got the order wrong: first flash recovery, then do the factory reset using recovery. Don't use the wipe option on the bootloader screen.
There are several versions of TWRP, usually named -ics, -jb and -42.
Don't use the -ics or -jb versions with the new bootloader, but use a -42 version for flashing CM 10.
For flashing CM 11 you need yet another variant of TWRP that is not available from the official download site. Check the CM 11 thread for a download link.
Be careful, using the wrong recovery can result in an expensive brick.

Ah okay - but this leaves another question: Why exactly do I need the Asus ROM when I already have a 4.2 recovery? Shouldn't Cyanogenmod 10.2 take care of the bootloader then?

No, CM does not include a bootloader. That is only included in the stock ROM.
That bootloader runs early before the CM Linux kernel is loaded.
The "4.2" recovery only means that it works with the updated bootloader ASUS introduced with the Android 4.2 update. Sorry, I know it is confusing. Thank ASUS for giving us all those incompatible bootloader versions.

[Q] Temporarily bricked after trying to boot into CWM

I just got my TF700 the other day. I was able to downgrade to .30, root, and unlock the bootloader without incident. I just pushed CWM per this thread: http://forum.xda-developers.com/showpost.php?p=31556045&postcount=1. I tried booting into CWM, got the standard quick vibration but the tablet was dead after that. I messed around for a while and finally after holding the power button several times in a row, it booted as normal. Battery is at 80%
Before I go any further, what just happened? Can I push CWM again the same way to re-install it? How should I proceed?
FWIW, the checksum for download 1 on the page mentioned only matched the checksum for #2. I used #2 because it matched its MD5 as it was listed on the page.

The proper way to do this is to upgrade to the latest stock JB (10.4.4.25), unlock, and you can either fastboot the recovery or unlock it be flashing Superuser. It is not advised to downgrade,even if it seems easier, because if you do it the way I stated, everything will be latest and should not have any problems whatsoever. since you downgraded to ICS, you now have a ICS bootloader. an ICS bootloader will not boot JB, nor vice versa. so now you will need to flash a JB bootloader, which will not boot the stock ICS, so you will now need Cromi, Cyanogen,or another custom rom to get it update with JB. Make sure you have them preinstalled on a SDcard before doing any more flashing.
If I am wrong, hopefully someone will correct me.

The writeups I had seen prior unlocking said to downgrade to .30...so I did. I am still sitting on .30 and am planning on installing CM 10.1 which I have on both the TF700 internal and an external SD card. The only problem is what I mentioned above where my device wouldn't boot into CWM and subsequently locked up for about 15 min. Should I upgrade to JB .25 prior to booting into CWM and installing CM 10.1?

I CM10.1 requires the JB bootloader, If you install CM on the ICS it wont boot. I dont see why the recovery is the problem. I would try updating to JB bootloader, use the zips in Cromi's second post, and then try installing Cromi. Downgrading is only recommended if you want to stay on a locked bootloader. Otherwise, you should flash the root.then install recovery, or simply fastboot it.
In order to install CM you will need to update the bootloader, then once it is updated you will not be able to boot into the ICS rom, so you will have to already have CM10.1, also dont forget google apps, so it can be flash afterwards.
IF CM is installed with the ICS boot loader it will just not boot, it will go into recovery but that is it. I dont see any probability in bricking your device. But I am only a newb, so you may wanna wait for another's input.

Or you could install the 10.4.4.25 stock, then just fastboot a recovery. I mistakenly said root with zip, you cant without custom recovery so scratch that, the only way to install custom recovery via the method I gave is fastboot. Or the way you did so, but that requires more steps and upgrades. Also greater chance of bricking. This is because of the incompatibility of the rom, boot loader, and recovery. If you have latest recovery,I would install the bootloader, then flash CM10.1 + Gapps and should be good to go.

Just remember for future reference, keep things up to date,or at least compatible with one another or you will run into trouble later.The #1 reason for tf700's bricking software wise is people do not update their bootloader as they update their recovery. Just keep things recent and you should have not a problem.

[Q] REQ Complete Guide to installing CM10.1 Nightlies on TF300T

Hi All,
I am looking for a complete guide (or links to various parts) to install the new CM10.1 nightlies that started on 5/19/2013.
I've been looking through XDA and I see a lot of information that's dated for the 4.2.1 and earlier, but nothing that confirms these steps work for these new nightlies.
1. Unlock BL using ASUS v8? (I am on 4.2.1)
2. Root it (how, what procedure should I follow and which files)?
3. Which BL should I install? I've been using CWM on my GS3, but a lot of these guides use TWRP. which versions
4. This guide looks dated, please confirm
http://forum.xda-developers.com/showthread.php?t=2055430
5. Any recommendations for a better ROM? Or is the CM10.1 the best for this tablet?
6. Since I have the WIFI version of this, I am assuming I dont need to worries about the baseband updates that were recently required for the CM10.1 updates? If I am wrong, please advise.
Thanks for you help in advance!

Most of your questions have already been answered multiple times. Ill do my best to summarize the answers ......
1) V8 unlocks most although there are some who arent able to unlock after having things come back from Asus from repair.
2) Unless you are stuck on a locked bootloader, skip rooting if you are planning on installing a custom rom..... why waste your time rooting something you wont be using? If you fall into this category, your option are limited but there is a way to root without TWRP or CWM.
3) Personally I have found that the 4.1 bootloader version 10.4.2.20 seems to play nicest with my tf300t. This of course means im stuck using Roms made specifically for 4.1 bootloaders. Im using twrp 2.4.4.0. Instructions on downgrading firmware are all over, but im pretty sure you must have an unlocked bootloader for this as well. Its a simple fastboot command to push the older system blob file to the device. Relatively easy.
4) Cant comment as I dont use CM
5) Im using CleanRom Inheritance and found that it not only benches higher, but runs much much faster than anything else I have tried on my tablet. I started with the latest 4.2.1 ROM and Bootloader. After trying everything out and everything lagging on my tablet, I decided to downgrade firmware. ROMS are nothing but personal preference, but, I find personally that Cromi ( for 4.1 ) along with Unter's kernel,makes my device smooth as butter. YMMV
6) Again, I cant comment as I dont use CM. Maybe someone else can chime in on this ? There are PLENTY of rom options available. Just try things out and see what you like best. Just remember to read the roms OP very carefully to make sure you have the proper bootloader installed for it. You can brick your device if you mismatch the rom and bootloaders.

First of all, thanks for the quick reply and detail!
1. I have a new one - so hopefully I should be ok. But I'll use v8
2. Great point, duh! The ROMs are already rooted!
3. I'd like to stick with the 4.2.2 bootloaders since my other devices are all running the same stuff. I haven't used TWRP before - any preference to that versus CWM?
4. no worries
5. I'll definitely keep in mind along with your bootloader suggestion should I downgrade. I've felt the lag with the ASUS Stock 4.2.1 ROM and all it's bloatware - I'm expect an immediate change right there with a clean rom.
6. yeah that is the primary reason I am asking about which bootloader to use with CM10.1's new nightlies.

To be honest, the lag is still there accross all the 4.2 roms I tried, even debloated. Its not as bad but its still there. My alternate device has a beastly exynos in it so im used to a perfect smooth experience. I notice even a little bit of jitter and it drives me crazy ( hence why I downgraded to 4.1 ) .
As far as what bootloader to use for which CM rom, each will tell you which to use specifically. I saw there is a cm10.1 for 4.2 and for 4.1. Just make sure to match things.
I used to be a CWM user all the way, but twrp does trump it in features and usability, especially for the transformer series. I beleive there is only one single twrp that works properly on the new bootloader for stock based roms ( no cwm will work on it at all). It ends in .42 so make sure you flash the correct one. If not, your partitions wont be writable.
One MAJOR warning.........
Do NOT use the wipe / factory reset on ANY bootloader. You will brick your tablet!!! Permanently!!!!
You can ONLY use the wipes inside of twrp / CWM.

Im assuming you are flashing CM10 then? The only important thing is fully read the OP and match your bootloader to whatever one they tell you. Its generally not a suggestion, but an actual requirement.
Mines a 32gb so I keep all of my backups and rom flashes right on the internal storage. I feel its safer in case of SD corruption or an accidental wipe. It doesnt hurt to have it in 2 places though ( backup your original rom to SD card but keep everything on the internal as well ). I always flash from internal ( roms and nandroids alike ). Ive never had an issue.

so this is what i've done so far and am stuck now it seems. probably a mismatch between the CM ROM and the BOOTLOADER.
1. Installed TWRP 2.5.0.0 - version ending with 42.
2. From the Wipe -> Advanced in TWRP, I selected SYSTEM, CACHE, DALVIK CACHE, and DATA (skipped the last two options).
3. I have the ROMs/GAPPS on my external SD card (and backup now too)
4. I installed today's nightly CM 10.1 for TF300T and the 20130301-signed (per 4.2.2 CM builds).
5. Reboot (via TWRP, Power Off)
I hit the power button to turn on and it gets stuck at the ASUS screen. Cannot boot into ROM either via the Android icon in the Bootloader menu.

I have the matching ASUS bootloader and TWRP combination this the ROM needs.
As for the CM10.1 - looks like for TF300T they are still using the older JB requirements... but still researching.

yeah so that worked fine. the CM10.1 version must require some different combination.
taking your suggestions now and downgrading to the 4.1 bootloader. will also install the CleanInheritance rom.

So just for other people out there... if you want to run the TF300T downloads from get.cm (the nightlies as of now).

1. 10.4.2.20 - TWRP 2.5.0.0 - JB
2. CM 10.1 5/25/2013 Nighty (This is a 4.2.2 ROM - requiring the JB, not 4.2 bootloader - i imagine at some point this will be updated)
3. GAPPS 20130301-signed
ah so nice!

[Q] Currently on Cromi 3.4.1 (Android 4.1). How to move on?

A while back I installed TWRP and Cromi version 3.4.1-10.4.4.25/US DEODEX. My tablet has gotten infuriatingly slow and I think its time to move onto a newer and better rom. I wanted to try out the 4.3 Cyanogen Rom, but the requirements are to be on the asus 4.2.2 bootloader. How can I go about updating the bootloader. Do I have to revert to stock first? What process should I follow? Thanks guys!

The safest method is to download the latest firmware from asus extract it and flash the .zip with trwp, from here it will overwrite twrp after you reboot so set up android 4.2 and then reboot go into fastboot and fastboot flash twrp 2.5 from there you can flash what ever 4.2 rom/kernel you desire

If you liked Cromi, you will love CROMi-X, the JB 4.2 based successor to Cromi roms.
Boot into TWRP and make a nandroid backup - just in case.
Backup your files, pics, videos to your PC or a SD card - just in case.
Go to the CROMi-X thread, download the 10.6.1.14.8 bootloader/TWRP 2.5 package, flash it and boot back into your old Cromi rom once.
Boot back into TWRP (which should be 2.5 at this point), choose 'Wipe', swipe to do a factory reset (highly recommended if you move from 4.1 to 4.2 since 4.2 file system is quite different from 4.1)
Flash CROMi-X 4.7 - enjoy!
You will probably find all your files, pictures etc on this clean installation anyway since a factory reset in TWRP leaves the data/media folder untouched, but backing them up is just good computing practice.

+1 this is the safest method, but once you have the latest Asus software installed use motochopper to root then use Goo Manager to install the latest twrp which is v2.6.0.0.

I do not see a reason to flash a stock rom. You loose your recovery, you loose root and have to start all over.
And I will stick with TWRP 2.5 for the time being. 2.6 has been OK for most users, but some had problems with it. And I don't take chances with my recovery - ever.

I was only helping the guy to upgrade to the new bootloader and at the same time as installing the latest Asus rom. Yes you will loose root and recovery but motochopper works so easy on a fresh install and recovery is really easy to install using Goo manager. I use this method every time an update is released and available to download from Asus support.

TWRP higher 2.4.4.0 giving weird screen

Greetings. Today I wanted to try a KitKat rom on my TF300T (currently on PacMan Rom 4.3), but as I've figured out, I needed a new version of recovery, since I was using TWRP 2.4.4.0.
So I flashed it (version for 4.2 Bootloader, of course), but even though I've tried nearly all versions higher than 2.4.4.0 (for ex. 2.5.0.0 or 2.6.1.0), I was still getting this weird screen (not my picture, but the same problem) and the only way, how to solve it, is to go back on my default TWRP version - 2.4.4.0.
Any help is much appreciated!

Which stock rom were you on, 10.x.x.x.x.x?
Hello and thanks for quick reply! My stock rom was 10.6.1.8.
Anyway, some really weird thing happened - I downloaded TWRP 2.6.1.0 (again, version 4.2BL), flashed it, went to recovery but whoa - It installed CWM 6.0.4.5...? How is that even possible? And yes, the blob was downloaded from the official TWRP site.
Anyway, with this new "TWRP" (aka. CWM ) I was able to install this KitKat rom, but still I would like to know the solution for the TWRP problem.
But still, truth is, that my stock rom is very old, going to update it then - Thanks!
EDIT: Ah, now I see it, my bad Just found this:
If current bootloader = 10.6.1.8 - JB 4.2 - recovery to flash = ONLY TWRP "openrecovery-twrp-2.4.4.0-tf300t-4.2.blob" - flashing a non-4.2 version of TWRP or any version of CWM will brick device. Also flashing 2.5.0.0-tf300t-4.2 on the 10.6.1.8 bootloader results in a split-screen issue.

Yes, update to 10.6.1.27 to use the TWRP.

[Q] Some questions before flashing

Hi guys,
I want to ask you some questions,I never flashed my tab.
1. Is it this TWRP file I have to flash ? http://techerrata.com/file/twrp2/tf300t/openrecovery-twrp-2.6.3.0-tf300t-4.2.blob (I'm on stock official Asus 4.2.1 now)
2. If I go on CM11 for example, can I revert to stock Asus 4.2.1 ?
3. If I go on CM11, can I flash on it a CM 10.2 rom for example ?
And does the keyboard work on custom rom like CM11?
Thank you for your help

1. That recovery will not work for KitKat ROMs like CM 11 or OmniROM. Check the respective ROM thread for a working TWRP. Also double-check the version of your bootloader.
2. Yes, read the sticky guides in the general section.
3. Yes.
When flashing a different ROM (not just another version of the same ROM) remember to do a full wipe: data, system, cache, dalvik.
If you mean the keyboard dock, yes that basically works in all ROMs I tried so far. Some ROMs don't support all the special keys, but basic typing works fine.

Hi,
Thank you for your answer. I have read a lot of guide, but I'm a bit confusing because I never used TWRP before and there is so much things to do ( adb, fastboot etc...)
Im on the lastest Asus official firmware so I think I need the TWRP 2.6.3.0 or .2 4.2 version. Should I do this before : http://forum.xda-developers.com/showthread.php?t=2545610? (install nvflash flatline )
Edit : And if I flash cm 10.2 stable, can I use TWRP 2.6.3.0 ?
Again thank you

Flatline is the best thing you can do for your 300... I would highly recommend backing up of your nvflash blobs.....
If you need any help with this just let me know, drop me a line at [email protected]
Thx as always Josh
Thank you. I will do it a little later, im now busy with my work.
Thanks again to you guys for helping me

Yes, that is fine.
The latest version from scanno (2.7.0.0) should work for both CM 11 and CM 10.2, but I am not sure the respective patch made it into that build, maybe only with the next update.
2.6.3.0-42 from the official download site is the safe choice for CM 10.2.
