bought tablet, and now? - Transformer TF300T Q&A, Help & Troubleshooting

Hello folks,
Just bought the TF300T Tablet yesterday.
It came with Android 4.1.1 preinstalled
Kernel 3.1.10 from Nov 22 21:27:42
Build No: JR003C.WW_epad-10.4.2.18-20121122
I read through many threads about rooting but i have some questions remaining:
How do i find out if my bootloader is already the JB-one which can't stay locked to root the device?
I mean that i can't use nvflash.
At the beginning i want to stay at stock rom, only rooted for removing ads purposes
After what i have read i only have the following options:
a) Install the already offered update to 4.2.1 and use Asus Bootloader Unlock V8. (don't want to unlock)
b) Stay on 4.1.1 and Use Unlock V7 (don't want to unlock)
c) update to 4.2.1 wait if i can root without unlook bootloader sometime
So if anybody haven't an other option i choose to update and wait. am i correct?
Thanks :good:

Now there is no option to get your installed or newer versions to be rooted without unlocking the device.
All your options are correct.

Well your on 4.1.1 which is jellybean so you do have the jellybean bootloader and nvflash is not possible. The only way to root your tablet will require an unlock and custom recovery.

I'd suggest you to keep it stock for some time, so you would avoid some hw failures and warranty problems. I am happy enough with it, it's not perfect but ... nothing is
Proud owner of an ASUS TF300T stock and the "old faithful" SGS i9000 powered by AndroSlim

Since latest update it runs smooth enough

I chosed option a) and updated the tablet. After flashing Asus v8 apk i get struck with correct install of twrp recovery.
I don't see any files. I downloaded the official file from their homepage and read that there is a patched one in a thread.
gonna try this one this evening.

cleanROM is working on a very nice stock ROM with tweaks which is something you might want to consider if you decide to unlock

[Q] root & upgrade to custom firmware

Hi!
I recently acquired a B60 serial, TF101 that has the android version 3.1 ; with build number HMJ37.US_epad-8.4.4.11-20110711
The system is prompting for an update , I believe it is for the 3.2 upgrade, which I didn't do yet.
I am very much interested in getting custom firm ware installed.
I had an opportunity to read the forum, and just needed directions in the right way:
1. Should I upgrade to the V8.6.5.9 (Android 3.2) from the ASUS website or the OVA that the system is prompting me to do so? I am just concerned with the following statement from ASUS website: ※Firmware update cannot do *SKU conversion* and downgrade version .... I believe this means, I can't downgrade after?
2. I can use the Universal Rooting Tool that is discussed on this forum, but I believe in that case I need to do #1 above, is that correct? or Can I do it with the stock firmware that I have?
3. the custom firmware I am interested in is the Android Revolution ; it says it requires: Clockworkmod Recovery - using the #2 mentioned above, will it be installed automatically?
Thanks.
P.S. Let me know anything else that I have missed.

[Q] Flash UK MZ604 with US MZ604 4.0.3 from MotoDev. Workable?

OK, I know there are a couple of threads on this general area but they're a bit outdated now and I thought there might be other UK MZ604 owners out there that might be hoping for an official JB update when the lucky US people get it.
So basically, we just need a bit of clarification on the following if one of you nice guys would be willing to help.
1. I've seen many success stories about people flashing the original 3.1 US IMG to a UK model. Should this still hold true if flashing straight to 4.0.3?
2. I'm assuming the process will remove CWM where installed, will this need to be re-flashed to enable the SD slot or is that a feature in the latest versions yet?
3. Is the market location based or tuned to the ROM (£ or $)?
4. Most importantly, will this process effectively make the device a GED and therefore ready for the 4.1 update when it airs? :silly:
Thanks in advance for any help offered from us poor saps in the UK.
Would it then not mean you would need to create US accounts as im assuming it will think you are now a US customer no matter where you are. If it wasnt geographic locked then why have the separation for all these images ?
Is there a 4.0.3 IMG? I have only seen the 3.0.1 version for all regions

Installing a US ROM makes it a GED. Flash HC, OTA up to ICS.
Market is based off your IP address I think. Either way, it uses your home location.
Unsure on SD card. I have a feeling it might work on ICS.
CWM is indeed removed. To be GED and receive OTA, you need to be non-rooter with locked bootloader.

unlocked bootloader is fine too - i got all my OTAs with an unlocked bootloader, no rom, no custom recovery, everything is stock (apart from the unlocked bootloader)
Absolutely possible to do this as I did this a couple of weeks back due to Motorola's terrible non-US customer support!
Flashed to US GED 3.01 rom then took all the OTA updates to ICS 4.0.4 and hopefully the Jellybean release. I have no issues running the US GED ROM in the UK other than the niggling regret for not bothering to do it sooner and wishing I never bought a Motorola product in the first place!

Hi,
What process/thread did you use/follow to change your device to a GED? I have read a few which seem to be US hardware specific only and I am not sure which one to use :-(
Also what impact will it have if you have noticed anything? e.g. fill I loss access to iplayer as the device is a US one etc?
Thanks

Ah...so SD Card access? Will it still read/write to it or is that still a custom recovery feature?
Thanks for your help.
N.b. Bongo - iPlayer is area-specific so as long as you're in the UK, it should work fine.:fingers-crossed:
100% ....
100% On My MiddleEast Xoom MZ604 ...
1) Unlock the bootloader (Warning: Unlocking the bootloader may void your wty and wipe all user data (photos, etc) from your Tablet)
adb reboot bootloader (wait for the Tablet to reboot)
fastboot oem unlock
fastboot reboot
2) Grab HWI69 for the Moto site (http://developer.motorola.com/products/software/ )
3) Extract and run the following commands:
adb reboot bootloader (wait for the Tablet to reboot)
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot reboot
Warning: Do not re-lock your bootloader. Doing so will apparently prevent the Xoom from booting.
4) When the Tablet reboots, let it go through the OTA process (HWI69 -> HMJ37 -> HTJ85B -> HTK55D -> HTK75D -> IML77 (ICS))
5) Enjoy ICS
Keep in mind that flashing a 3G or 4G ROM from US might not make your device data connection from another country work. But GED is a good way to bypass those annoying waiting times.

You actually can re-lock the bootloader, but you must do it before any OTA updates (immediately after flashing the US images)

Get back the original software? JB 4.1.2

Hello guys,
I received my razr HD (925) today. It was already updated to 4.1.2.
Coming from my galaxy s2, where obtaining root is pretty easy I followed the first of your guides here - but failed at reading correctly:
I tried the "all in one tool" to get back to ICS to obtain root using the rootkeeper.
Something went wrong, the SW remained 4.1.2, but I had no radio signal any more (only verizon version I read lateron)
Now I managed to flash a france 4.1.1 s/w using RSD 6.1.4 - still having no root but can use it again, at least.
Is there any chance to get my (newer) original version back? At best rooted?

Maybe I should add, that it looks like my main problem is to find the up to date SW that was installed.....
Maybe I should send be back to my provider, get a new one and then do a dump / image and upload that BEFORE I "brick" it again =)
I would try to hard reset it and then try Matt's tool to go to back to 4.0.4 again.

To the other guys:
THanks, I'm going to unlock the bootloader then. Unfortunately it looks like some things have been changed in the factory delivered 4.1.2 so that not even safestrap is working any more.
With a locked bootloader the revert to ICS is not working.

There are two reasons right now:
- I'm from germany and here we have seperate restrictions for warranty and guarantee (one is forced by law, the other is provided by motorola).
Motorola is not doing to repair unlocked Razr HDs
- My phone is new and I'm not sure whether I'm going to keep the Razr HD - unlocked it might be a problem to give it back to my dealer during the "test month" he offered.
(I still have my Galaxy S2 and had LOTZ of fun with new custom roms, trying different combinations, getting all the newest stuff ported right after it has been leaked anywhere for any modell - and on the other hand, there is not even the source to get my retail software back because no one shared it)

[Q] Questions Newbie rooting/unlocking/roms/linux

I've had the asus tf300 for about half a year now and I think its time to customize it. Ive looked at forum post on unlocking the bootloader and rooting but they them a little outdated. Can anyone at least point me to relevant forum posts addressing my questions for the
Asus tf300
Running android 4.2.1
Build JOP40D.US_epad-10.6.1.8-20130225
1. Does the asus bootloader tool work for my tablet? I am asking because it says : Only suitable for Andriod4.0 Ice Cream Sandwich & Jelly Bean OS version.
2. Does unlocking the bootloader also root my tablet
3. What are some popular stable custom roms?
4. Are there any stable releases of linux for the tf300? Preferably dual boot, but if not running linux in place of android is better
5. Where can I find information regarding recovery and security tools to protect my tablet while its root it and prevent it from getting bricked?
6. Please add any extra information you think a noob might need to read before and after unlocking/rooting
1. Yes if you download the official asus apk you can unlock your bootloader.
2. No...unlock is unlock and root is root two separate things
3. LOTS depending on version
Use the search tool for all other questions but in short atm you cannot do anything except unlock and MAYBE root as the new firmware has a different encryption prevent recovery to access certain important locations.

1. Yes. Asus just released v8 which works with the 4.2.1 version which you said you're running so I assume you recently updated.
2. No. Rooting is separate from unlocking. Unlocking allows you to flash files to the system and other partitions, like root files
3. Sorry I run stock unlocked and rooted, but see the Dev section for many opinions.
4. I've heard this and that but can't confirm sorry.
5. Find twrp in the Dev section. Since you're updated you must get v2.4.4.0 which is the latest.
6. I was a noob too. Just read carefully and don't screw with something if you don't have knowledge of what it's for good luck.

Hi, I am running the Resurrection Remix Final N ROM on my g900v and I have this bootloader (g900vvrs2dqb2). I looked it up and saw that it was from February 2017.
I would like to update my modem and boot so I am ready for Oreo but I'm not sure best way to go about it,(Odin)?
I know this information is available on XDA and probably in this forum, but I am paranoid because I had a hell of a time unlocking the bootloader because I was fallowing old directions.
I would be very grateful to anyone willing to point me towards simple, but accurate directions.
Thanks in advance, and apologize for my ignorance!
Sent from my kltevzw using XDA Labs
Awesome! Thanks very much. I'm gonna give this a shot like the previous install/upgrade some time Friday afternoon PDT.
Jeebus I need sleep....
Can I flash this over LOS in TWRP to return to stock or do I have to use Odin?
Once flashed will the bootloader remain unlocked to allow me to reinstall LOS?
I got a new screen installed and it appears there may be an issue with how the digitizer interfaces with the software/kernal and going back to stock should update the software to allow the screen to function normally then allowing me to reflash LOS.
Hey Everyone,
Thanks for all your great work on the Galaxy S5. This thing is still kicking! I know I'm way behind on what's been going on. I'm still back on the TowelRoot days. The time has come to finally update my phone because some of the apps won't work anymore. I'm not into ROMs and stuff, I just want the latest firmware without all the bloatware. I had originally gone the TowelRoot method because people were having such a hard time with battery life (me included) with Lollipop. I was fortunate enough to get TowelRoot before updating to the newer version of Lollipop and went back to KitKat and I've been there ever since.
I'm currently on G900VVZW1ANCG (Kitkat 4.4.2) with root access and superuser. I have a CID 15 emmc which is a good thing from all the research I've been doing on XDA.
That's where I get stuck and confused with the newer stuff that's going on. Do I even need to unlock the bootloader?
In the end, I don't mind wiping the entire phone, I just want to get to the latest Marshmallow (which this thread seems to have) without all the bloatware or the ability to delete all the bloatware.

Welcome back!
You had asked some questions that is actually 2 separate ones upon themselves and I'll, hopefully, try to answer them...
Question 1: Should you unlock the bootloader?
Answer 1: The only need for anyone to require this is if they want to perform something outside the scope of just Rooting a device.
What I mean is... for example, if an individual would like to install a Custom Recovery and/or Firmware then you will need to unlock the bootloader.
Question 2: You would, ultimately, like to just debloat the Firmware?
Answer 2: Debloating Stock Firmware only requires root and not an unlocked bootloader.
The proper rooting of a device just means that you will be able to modify areas of the root directory that's restricted for devices without root and Debloating falls into this category.
Just an FYI regarding the following 2:
1) The 2 differences between the CID11 & CID15...
GS5 with CID11 = Toshiba EMMC
GS5 with CID15 = Samsung EMMC
2) There are a handful of Custom Firmwares that are based upon the stock Firmware that is already Debloated. Some of them only requires a Rooted device and Some requires an unlocked bootloader and recommends a Custom Recovery like TWRP.
This is just a brief summary to help you further but, I would recommend that you take note of/highlight the following 2threads that would be a bit more helpful depending on what your looking to do.

From this post here, I think the way to get this done for an unlocked bootloader is:
- flash the HOME_No version using Odin 3.12 AP option
- flash TWRP via Odin AP
- reinstall Magisk from TWRP and Magisk Manager.
1) Will that work?
2) What’s the most reliable tool for creating a backup—a) in case I screw up, AND b) in case everything goes well, so I can restore my apps and data into the new clean phone, preferably without screwing up the new clean phone?
I have a G900V.05 on QB2, rooted and unlocked bootloader and custom recovery, that I got to using this method by jrkruse and a false start via another method. So I’ve got Titanium Backup, TWRP, and FlashFire all in play. I'll probably shoot out backups from all of them, not sure which one restores best or if FlashFire survives the update.

1) -Yes, I just tried it, and it works perfectly! The only correction - you have to unzip
G900VVRU2DQL1_G900VVZW2DQL1_G900VVRU2DQL1_HOME_No_Aboot.tar.md5.zip file and flash md5 file with Odin (Odin won't work with that zip file).
2) -I have exactly the same question to fellow members - what is the current most simple and reliable method of full system backup (like ghost image for PC)? I want to try Lineage, but I already spent many hours on system customization (applications, app settings, accounts with login names/passwords, etc.). I really need some fast method to revert phone back to QL1 with all my current setup. I will flash again System and TWRP from Odin, and Magisk from TWRP. How can I then restore my full setup with one click? I used to use 'Titanium Backup' in the past, but that is not an option anymore. It freezes every time when I try to restore 'All apps with system data'
Thank you for reading that and for any possible advices.
So, if I have an unlocked bootloader, will it stay unlocked if I flash the boot from the "Developer Bootloader Friendly/No Aboot No-Wipe Firmware" version? Will it upgrade the baseband to the latest version as well?

Thanks. Are the baseband modem firmware also included in the QL1 "Developer Bootloader Friendly/No Aboot No-Wipe Firmware"? I've been told I should upgrade both my modem and bootloader, but I don't want to re-lock my unlocked bootloader.
WTF?? I was running TWRP 3.2.1.0 and crDroid 7.1.2, and I used Odin to flash the "Developer Bootloader Friendly/No Aboot No-Wipe Firmware" and checked the BL and CP options, which I thought should update just the bootloader and modem, and now it boots up with the Samsung logo and then the Verizon logo, and then just sits there. I tried to go to recovery so I could restore a backup, but it looks like the stock recovery. What did I do wrong and how do I fix it??
Since crDroid 7.1.2 is older than the bootloader, I'm wondering if that's the issue. I do have crDroid 8.1 on the microSD card. I also have TWRP 3.2.1.0 on the microSD card. So I'm wondering if I can use the stock recovery to flash TWRP. I haven't played around with custom ROM's in four years, but prior to that I did it all the time, so apparently I now remember just enough to be dangerous...
@Nerva, I apologize for the delay but, I'm curious to know where, why and what gave you the impression that you were/was required, on your your working device, to update your devices bootloader???
I'm just perplexed about this...

Your situation prompted me to confirm what I knew and others that you can see on the recent posts on the following thread...
https://forum.xda-developers.com/showthread.php?t=2259645
... I just wanted to state that if your devices bootloader was already unlocked and the device wasn't bricked (or similar) then you should not need to update the bootloader or it'll lock it up again and, potentially, can even cause FRP issues as well. Luckily your FRP didn't trip and the device was able to be unlocked again.
I have the same device that was unlocked a long time ago and never ever needed its bootloader updated.
Your question regarding the Baseband Modem Updates...
Those are the Modem files extracted from the stock Firmware and only updates the devices Modem. That controls the WiFi, Carrier Data, etc...
This is similar to updating the Drivers for something specific on a PC (like the PC LAN, WiFi, Video Card, etc... ).
When you had flashed what you did on your device, you basically flashed an optimized version of the Stock Firmware. This is why you saw the Samsung Boot Screen.
I hope that I had explained this okay via text...

I'm curious, if the bootloader version has so little importance for us custom-ROM users, why does Samsung/Verizon update their bootloader versions -- to what purpose?
It looks like this website will generate a cf-auto-root package for QL1:

I'm wondering if I flash that with Odin, would it upgrade my current unlocked QB2 to an unlocked QL1?

I'm not stating that Bootloaders doesn't get updated upon themselves but, they specifically seldom require it.
One way to look at it is that the function of the bootloader is allot like the BIOS of a PC. They both handle the boot process and seldomly require to be updated specifically.
When a new Stock Firmware version is released, the bootloader is only updated accordingly to reflect the updates of the firmware. This reflection is to protect the device from being updated to an incompatible firmware version.
In short, when the bootloader is unlocked, the bootloader still protects the device from an incompatible firmware from being installed but, it being unlocked just bypasses the "Samsung Stock firmware only" restriction.
TWRP is just the conduit between the Firmware and the bootloader that just handles the communication between the bootloader and the Firmware.

If you flash the firmware, your just going to relock your bootloader and be back to stock.
To get the QL1, just flash the Baseband Modem Update from the following link and you'll be good to go and you'll see this in your device info.
