Hello forum,
Device: tf300t Jb 4.2.2
I was trying new roms ( cm10.1 from surdu's, aokp r06a, franco kernel, CROMi-Xenogenesis DEODEX and others) and some of them work and others didn't really worked.
During the installations I used CWMR v6.0.1.3 and used all the standart procs like format wipe cache/dalvik etc.
Since I wasn't able to overclock with the roms that worked on my tf300t, I decided to install my initial functional rom cm10.1 > with perf kernel.
This time when I turn on the device it wont get past the initial bootscreen (black screen/white asus logo). It just loops and loops in an eternal cicle rebooting constantly.
I'm not sure if the tablet is bricked or not so I don't really know what procedure should I use to fix it... Could use some help please.
I don't really understand why some roms didn't work in the first place, I used the same procedure installing other roms and they worked fine....
They were compatible with device and jb 4.2.2 as far as I understand... I don't know what I'm missing.
Thank for your time and attention.
The best regards,
Absinto10

The bootloader you show above is not a JB 4.2 bootloader but the very 1st asus JB 4.1 - 10.4.2.9 bootloader/firmware
You will need to upgrade your bootloader depending on which roms you would like to flash, some roms are 4.1 compliant and other are 4.2 compliant so read the rom op for info on which bootloader you need for that rom.
Have a look at my how-to in sig below for info on how to upgrade your bootloader and which recovery is safe to flash for each bootloader.
Let me know if you need any help with any steps or info.

Thank you so much. I read your how-to tutorial and I think I already understand the process. I was a little bit confused because when I first flashed my tablet I didn't have enough experience with some android slag and definitions and I forgot which bootloader I was using.
Yesterday I couldn't install nothing via fastboot protocol but when the battery died and after charging it I was able to install other firmware(oficial) via fastboot. With the frustration, I installed WW_epaduser_10_4_2_20_UpdateLauncher, then with no success booting this I installed WW_epaduser_10_4_2_9_UpdateLauncher again.
When I read your tutorial I was very optimistic and things started to make sense... but when I tried to apply it, I couldn't install nothing via fastboot again (no blue bar) --". On the terminal it only says after clicking enter: "sending 'recovery' (7766 KB) or "erasing blah blah transfering files"..." And nothing happens...
Is it fast boot bricked? I don't understand why, there's no reason for that i guess!! Well I'll wait 'till the battery dies again and attempt to apply you tutorial once more.
Meanwhile reply please and thank you very much for the assistence

Hello my friend once more
So forget the last posts I figured out the problem... So I was fastboot bricked and the only way I found to fix this was it in this post http://forum.xda-developers.com/showthread.php?t=2236885.
So I used he's bootloader.bin so I could "unbrick" my tablet and the fastboot commands. Afterwards I followed your tutorial always using "WW_epad-user-10.4.2.20" (stock firmware) and "openrecovery-twrp-2.5.0.0-tf300t-JB.blob" and everything worked fine. Installed the firmware, twrp, wipe cache/dalvik etc and flashed zip from external sd card. When I rebooted the blue bar and "signature matched" appeard on the screen and loaded just fine, but when it reboots again, the bootloop starts :'(.
This time when I entered again on the bootloader, Twrp was erased of my tablet...
Installed trwp again and on my bootloader I have this current information: Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.4.2.20-20121228" A03. Fastboot commands work fine so, as far as I understand, there's still hope for poor tf300t x).
I think the problem is the bootlader.bin version but idk. Please help I'm really getting frustrated with this. I'll wait for your reply because I don't want to cause anymore damage to the device :/. Thank you
Ok from what I understand the fastboot flash brick is caused by flashing a non-4.2 version of twrp or any version of cwm on a 4.2 bootloader, but as this was not the case for you I'm not sure of why you were unable to flash via fastboot until the tab had been drained and then recharged. Sounds like similar symptoms to the fastboot flash brick but I don't think people with the fastboot flash brick are able to flash at all even after the tab has drained and been recharged.
I have not heard of anyone with the fastboot flash brick (caused by above situation) unbricking there tab with the fix you tried in the above post.
However you seem to be in a different situation - the fix you tried in your post above, I believe will flash the bootloader bin file from the fisrt ICS firmware 9.4.3.29 which I thought could not be done if you have already upgraded to a JB bootloader.
When you first flashed the bootloader.bin did you happen to take note if your bootloader had changed to 9.4.3.29?
The reason I ask this is that I have tried before to downgrade from JB to an ICS bootloader and had no luck here, I would always get a "signature mismatch" trying to go from JB to ICS - but you appear to be getting this when flashing a JB bootloader. So now thinking this may be the first breakthrough in a way to downgrade from JB to ICS.
Your device is showing that you are now on the last JB 4.1 bootloader (10.4.2.20), so first I would try and flash the system blob for 10.4.2.20 again and see if that fixes the "signature mismatch" issue.
If not I have a thoery that may or maynot work, as you are getting this "signature mismatch" issue (after flashing the bootloader.bin for ICS) when you flash a JB bootloader. You could try (at your own risk) again flashing the ICS bootloader.bin from your above post, then reboot to bootloader and check what bootloader version you then have. If your bootloader is now saying 9.4.3.29 you could then try flashing the system blob from firmware 9.4.3.29 and see if the signature mismatch issue is fixed. If so you should then be able to flash a system blob from a JB firmware.
Not sure if the above will work but try flash the JB system blob from 10.4.2.20 first and if that does not work it's up to you if you would like to try the second.
If you need a step-by-step on how to do any of this or are unsure of anything above just let me know.

Hello once more
I just want to clarify two thing first.First, I was a little bit confused on the first reply I did. I was able to use the fastboot commands again because I used the bootloader.bin file not because the device uncharged ok? xD I made some confusion on that issue. Secondly, yes I bealive I flashed a rom only prepared for a 4.2 bootloader when I had the first jb bootlader installed (4.1 I believe). And thats what bricked my tablet.
I'm so sorry if I confused you, like I said earlier, I didn't use to understand a lot of android slag and definitions so I screwed up.
Yes I bealive it's a ICS bootloader. I'll do the proc once more and check the information on the bootloader screen and I'll let you know right away.

I fastboot installed the bootloader.bin but I still have the following information on my bootloader: Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.4.2.20-20121228" A03.
Should I proced and install a ICS firmware like WW_epaduser9_4_3_30UpdateLauncher, TWRP for ICS and then flash the WW_epaduser9_4_3_30UpdateLauncher.zip from my ext-sd card?

No if the bootloader is showing 10.4.2.20 then the bootloader.bin did not flash to the tab.
Did you try flash the system blob from 10.4.2.20 again?
If yes and it did not fix the mismatch issue and bootloop then maybe you could try flashing system blob from a 4.2 firmware like 10.6.1.15.3 and see if that works

Thank you so much my friend, we've done it, she liveeeeeeesss!!
Flashing system blob from 10.4.2.20 wasn't working. Even though, signatures were matching the bootloop started again.
So I decided following your second advice flashing system blob from a 4.2 firmware, but insted using 10.6.1.15.3, I used "TF300T-WW_epad-user-10_6_1_8UpdateLauncher". Then installed Twrp (openrecovery-twrp-2.4.4.0-tf300t-4.2.blob) and did the following steps of your tutorial (wipe/flash rom) and voila, it booted .
So let me see if I got this straight, currently I have 10_6_1_8 bootloader and 4.2.1 android right? So I can flash this rom for example:
[ROM]★●[TF300T/G/201/301][CROMi-Xenogenesis 4.6.6][ODEX/DEODEX 10.6.1.15.3]
Rom Link: http://forum.xda-developers.com/showthread.php?t=2204166
Thank you so much man!! You saved my little tablet xD

There are many many posts covering all these type of questions, you need to read them
If you hit a new error and can't find an answer in Google/XDA then post.
Also were you on UK 4.4.2 ?? I don't think anyone has this yet.

So i have successfully rooted my droid razr m and unlocked the bootloader. i tried using safestrap to avail, i it didnt work at all. Then i tried clock work recovery flashed through with adb. It got flashed successfully. Then tried to get recovery open didnt work. I wanted to know if the unlocked bootloader message is the cause of both programs not working. or can you guys give me maybe better instructions to start flashing roms on phone on a rooted and unlocked bootloader. THANK YOU. I wanna put a rom on my device so my phones themes look cool.
I am also on 4.4.2 stock. and how do i get rid of the unlocked bootloader message.

you don't need ss any more with an unlocked bl, although it should still work. however, the version you tried probably isnt compatible with kk.
as for cwm and twrp, make sure you have the correct version for kk, and after you install it you want to boot directly into it. do not let the phone boot the os the first time or it will wipe the recovery back to the stock one. also you should grab the su flashable zip and flash that when your in recovery the first time, so you have a properly working root.
after all that you can put a rom on your phone and flash it, but make sure you get one that is on kk base or it will just bootloop.
there is a method to remove the ul bl warning, check you forums general section for the post. i know there is one in the maxx/hd forum, but i don't know if they are cross compatible.
XT907
So is there any downloads i need. Can you be alittle bit more specific. I am stuck i can root i can flash 4.4.2 kk. Just need help with flash =ing custom roms and what i need for it. Thank

Sprint Edge with stock lollipop. I tried to root using odin, not sure what happened. Im an idiot, Im leaving for work in 3 hours i cant get my phone going again. When i try and use Kies it asks for a code which i dont have. Can someone give me the correct CF-Auto-Root file??? PLZ help im lost in a sea of information!
Do one thing flash twrp recovery and then u will be able to boot normally..for rooting install su.zip using twrp recovery
Do you have the stock firmware? Get it and Odin to get you going again.
can anyone help me downgrade my note edge n915p from lollipop to kitkat, i tried flashing thru odin but it failed showing error, i want to unlock downgrading the firmware to kitkat...
so it looks like the only place i can find the stock firmware is SAMMOBILE?
Ok i got it! I flashed recovery as advised
All good?
Hey All,
I have a Moto G 2013 (1st gen I believe). A while back, I wanted to install lollipop without it being available so I flashed the Brazil 5.0 ROM. Now, for some reason it won't boot and I got my phone stuck in bootloader. I can go to TWRP and the bootloader mode right now. I'm not sure what version it is, but I think its the XT1032 (non-lte for sure) and I've used it on Bell, Canada
.
I'm trying to follow a guide to restore back to stock but im not sure which model I should be downloading the firmware for. Can anyone help?
I'm using this guide: http://forum.xda-developers.com/showthread.php?t=2542219 and I tried a XT1032 ROM (Brazil) but when following the first command "mfastboot flash partition gpt.bin" didn't work. Should I just ignore this and move forward? I believe somewhere in the thread it said to ignore it but I'm not positive. Note: I dont want service, I want to use it as a glorified mp3 player for my car
Thanks in advance and any help is appreciated!
EDIT: I tried flashing a couple of roms in bootloader mode via adb from the aformentioned tutorial, but I keep getting errors when trying to flash the recovery, boot, partition, etc. Can anyone please help? Thanks.

It is strange that you can flash ROM in recovery but cant flash rec, my suggestion is checking your rec file,substitute with a Twrp rec and flash again. if success, you can try to flash a zip ROM.
Thankyou for the response! I appreciate it. Sorry, I should've been more clear. I was trying to flash official firmwares through bootloader, not roms. I tried flashing two different firmwares (XT1032, as per the barcode setting on my bootloader mode), and I keep getting errors when trying to flash using adb commands. It sends the files correctly but fails at writing them. I'm not sure what the issue is, but it may be because I was on Android 5 (lollipop) and I was trying an older firmware (i.e. older partition table). Currently trying a 5.0 firmware (brazil XT1032!) If anyone has any advice, please let me know! Thanks again!
