.21 root? - Asus Eee Pad Transformer Prime

So, I've unlocked my bootloader, and I just wanted to get rid of this bloatware. Do I just need to flash the recovery from adb then flash the superuser .zip from recovery?

Fastboot the recovery and then install a custom ROM. Since you've already wiped out your ability to recieve OTA you may as well go for something a bit better than ASUS stock + su.
This guide I prepared should be of assistance:
----
* Install ADB and Fastboot onto your system, as well as the universal USB naked driver which you can find on this forum.
* Search for DotTech install ADB and Fastboot - follow this guide, it's probably the easiest way to get a working fastboot and ADB environment up and running.
* Enable USB debugging on the tablet under developer options.
* Set up the universal driver, you'll need to reboot your TF201 and hold the POWER and VOLUME DOWN buttons until you see some text in the top corner. Do NOT press volume up to go into Recovery Image mode or you'll just walk into a dead end.
* Shortly after you'll see three icons, press volume down ONCE and then volume UP once, the USB icon in the middle should be highlighted and you should see text saying "Entering Fastboot Protocol" or similar.
* Plug the USB cable into the tab and the PC, test whether you have a working fastboot install by typing fastboot -i 0x0b05 reboot, if your tablet reboots without you touching it, then you've got working fastboot access. Remove the cable, reboot to fastboot mode as described above.
* Meantime, download openrecovery-twrp-2.1.3-tf201.blob from the team win site, and stuff it in the same directory that you set up Fastboot/ADB, rename it to twrp.blob. Plug your tablet back in and then issue the command fastboot -i 0x0b05 flash recovery twrp.blob , if this goes to plan you'll see a couple of lines of text on the command window which will tell you that it's been successfully flashed in. YOU STILL DO NOT HAVE ROOT THOUGH, SO NO SILLY STUFF
* Finally, download the ROM of your choice, place it in the base /sdcard directory, then reboot the tab and hold POWER and VOLUME DOWN, when you see the text, this time hit VOLUME UP, and you'll be sent into the team win recovery suite, at this point you can wipe and flash the newly prepared ROM as per normal.

Hope this helps.

[Q] Adb commands to install TWRP

So I unlocked my Prime on .21 and I've been trying to get a recovery on it with no luck. Obviously, I can't use Rom or Goo Manager as it's not rooted. I can't flash a zip file because I don't have a recovery. I've tried installing it in fastboot with no luck. From what I've read fastboot is not an operable command on the Prime so I tried installing the universal naked driver and using the provided commands with it. According to the directions I have to unistall previous drivers....I have a LOT. If that's the case I might as well try on a fresh PC as I have Moto, HP, HTC, Samsung, etc drivers installed.
Back on topic - TWRP's page ( http://teamw.in/project/twrp2/93) provides commands for "ADB / Terminal" to install their recovery but the commands provided are clearly for terminal emulator which I'd have to be rooted to use. So how do these commands convert to ADB?
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Any help is much appreciated! I really don't want to downgrade to root and install recovery. If I can't get fastboot or adb to work, I'll keep that as plan C.

Use fastboot it's easier. http://transformerprimeroot.com/tra...orkmod-recovery-5-8-2-0-on-transformer-prime/ and obviesly replace cwm with twrp.

I cannot get fastboot commands to work on my Prime. Do you have the Universal Naked Drivers installed and have you used this method?
Sent from my DROID RAZR using Tapatalk
I used this one and I didn't have to install any drivers, worked out of the box. What do you mean about you couldn't get fastboot to work. Did you also write -i 0x0B05 between fastboot and flash
?

* For the first occasion I -strongly- recommend you use Virtuous Prime-S as you can generate a solid backup environment out of it, as well as the fact it's not too departed from Stock, so it's a good way to break yourself in.

Thanks for the tutorial. I'm fairly familiar with adb and fastboot. My problem lies in the fastboot drivers. I was not able to install the Universal Naked Drivers. If I tried to install them over the existing drivers it failed. If I deleted the existing drivers, I was not able locate the device to install the new drivers. I would either reboot the computer OR unplug and plug the device in but each time the old drivers would auto install. Again, thanks for your input and I'll give this a go when I have some more time.

I had a similar issue getting the USB drivers in the first time. The best bet is to uninstall, unplug and then re-plug the tab in fastboot and then intercept the little window doohickey that comes up when it says it's dealing with an unknown device and tell it specifically not to go fishing on the web, then point it at the driver folder.

Just wanted to shoot a quick thanks. I finally found time to tinker with my Prime and turns out I had the drivers properly installed but was booting to recovery not fastboot, hence fastboot device wasn't found. When booted properly, it flashed the first try. I'm now TWRP recovered and Gummy rom'ed. Its amazing how one can overlook a simple step and until someone plainly states it, they never even question it.

[Solved] BAD FLASH!!!! NOOB. Possible Brick HELP THANK YOU.

So I have a Telus version of the HTC One X+ 64GB. I have been pretty familiar with flashing roms on samsungs. Wasn't the case so much with the HTC. So I decided to unlock boot loader, root, and flash a custom recovery. Decided to flash this rom from this thread. http://forum.xda-developers.com/showthread.php?t=2219520 not understanding how the boot.img works well guess what I didn't flash that. Now I'm stuck on the Panandriod 3+ boot logo. The phone from my understanding don't seem to wanna charge. Just gets a slow blinking red notification light. When I was able to get into recovery when the battery had charge I was unable to get the ad card to mount so I could add the boot.img to the phone to get fast boot to flash it. I have all the drivers installed on the PC but unsure if maybe the reason that recovery is unable to mount is because of HTC Sync is installed on the PC as well?
The whole reason for trying to flash a rom on this HTC is because I have the HTC One Developer Edition on the way and I wanted to learn as much about flashing HTC as I could so I wouldn't mess up and brick my HTC One when it came. Nowwwww I'm not so confident.
Two days research I have a little more knowledge but still unable to find a good thread or resource to fix this problem. I was able to get some charge thru to the phone when I selected recovery and it went to a black screen with the notification light pulsing red. It seems like its not fully bricked. I tried to use Cmd in windows to try and communicate and see if he phone would respond to the fast boot commands but to no lunch Cmd cannot find the phone. Do anyone know where I could start? Is there a tool kit that can send me back to stock? It was running 4.1.1 any help in the right direction would be great. Thank you guys.
You HAVE to flash the boot.img! Flash it in fastboot
fastboot flash boot boot.img
Without the new boot.img (which is the kernel) your Rom will not run.
Download the pizza boot.img

Hey thanks for replying
I downloaded the pizza boot.img but the issue I'm facing is charging it seems either very very slow on black screen or maybe it's not charging? But main issue is that PC cannot find the One X+ I will try this command but where do I place the pizza boot.img on windows?
The only thing is getting me is I'm getting the sound from windows when you connect a device when I plug the phone in USB but the cmd so far that I have tried even the All in one toolkit don't seem to see that the phone is connect USB in fast boot or boot loader mode. Think this is due to not enough charge? Plus should I just leave it in custom recovery to charge which is a black screen due to it says not enough charge to flash to charge my device?

I can hardly believe you didn't find anything that help you with this issue on this forum.
First is your SDK/ADB tool install on your computer?
It's not that complicated to flash the boot.img. Take the pizza boot.img and put it in your platform-folder of your SDk tool. Reboot your phone by holding Volume down and pressing Power button. In bootloader plug in your USB cable and at the prompt confirm that your computer is seen by typing this >fastboot devices if you have your serial confirmation then simply proceed with this at the prompt>fastboot flash boot insert_pizza_name_boot.img (enter) again at the prompt>fastboot erase cache (enter) the for rebooting >fastboot reboot (enter)
If you need more infos, you have everything required in my signature to help you.
Do you have the latest TWRP

Thanks Lucky, I noticed tonight I went thru everything in issues and I noticed that I didn't correctly have SDK set up right on my windows. Hopefully that this is the issue and that when I set it up right that I can fix this problem. This has been far different then Samsung to fix hahaha thanks again and kinda my bad for posting the question. But hopefully that works.

No I don't have TWRP I have the recover that came in the noob tool kit. The none touch screen one lol. But I understand a fair bit on what I should have done. I'm gonna try and follow luckies link for the SDK set up and see if I can send the zip file to the phone then flash it in recovery. Just I hope the thing can charge. I had it on the charger for 4 hours today and it still said that there was not enough charge to flash I tried charging it in the boot loop and in recovery.
So I guess the issue is worse. The phone won't charge at all the red notification light blinks red but it don't seem to be charging at all I have looked for fixes and it says flash latest compatible recovery but it won't even discover the phone connected to windows with proper HTC drivers installed
Is your phone capable of booting in bootloader mode?

Yea I am able Lucky. But what I tried today was to get RUU to recognize the phone to do that but no go. So tomorrow I'm gonna do a fresh reinstall on a new laptop of windows and install drivers again and all that. But as for boot loader mode it boots. I click recovery and I get a black screen. I can fast boot USB but I'm not quite sure about USB debugging is still turned on. If it where I'm sure I wouldn't have an issue with the PC not seeing the phone connected.
OK try this in bootloader mode with the USB plug
fasboot devices
Do you have a confirmation serial number?
Will do Lucky. Thanks for your time and patience. I will try this over the night. I really like to try and get this fixed and to understand how the htc works with installing roms and tweaks. I really don't wanna mess up my Develeper Edition of the HTC One that's on the way.
If you have your serial confirmation.
Download this recovery HERE
Move this file in your platform-tools folder
Press and hold the Shift key and right click on a empty space of that folder and select Open Command Window Here
In the command window with your phone in FASTBOOT USB mode
Type>fastboot flash recovery TWRP2500.img
(Success)
Type again>fastboot erase cache
(Success)
Unplug your USB cable
Hit one time Power
Select Recovery (Volume down)
Hit Power to Reboot in Recovery
Phone should charge in recovery even if the red light doesn't lit.
Just tried this on my phone with less than 10% and it worked flawlessly, after ~10 minutes my phone was at 13%+
Otherwise you will have to create a batch file and run it while your phone is in FASTBOOT USB mode :
Code:
" @echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
"
That should allow your phone to charge to the minimal required to flash or to re-unlock your bootloader.

[Q]Can I fix my soft-bricked LG Optimus Fuel

I was messing with my old tracfone and trying to install a custom ROM on it. I pressed wipe on TWRP and selected advance wipe and selected everything for factory defaults. After this, I restarted and my phone is stuck on the LG logo and won't go past it. I can't even get back into TWRP by spamming the volume up button. I also have a backup image, but what's the point if I can't access TWRP? Any help is appreciated.
Thanks
Wipe doesn't restore factory defaults, it removes everything. If you wiped system partition there's no Android on your phone, thus no system to boot. If that's the case, you can try to reflash twrp or install original firmware

If so, you need a PC, if it's Windows then download this tool - it's a system-wide fastboot that lets you flash software on your phone. It should also download drivers.
If everything goes OK, boot your phone into bootloader (you need to find the right key combination to do that, could be (phone off) power button+ volume down held for about 5-10 seconds, but I don't really know how it's like with this particular phone).
Go to the folder where you've got your TWRP, hold shift and press right mouse button. From context menu choose "open command window here"
In command window enter:
Code:
fastboot devices
if it returns your phones serial number it's OK, if it doesn't - you probably don't have proper drivers so look for them
If everything is OK enter:
Code:
fastboot flash recovery your-twrp-image-name.img
If this step is OK you can reboot:
Code:
fastboot reboot-bootloader
In the bootloader there should be an option to enter recovery mode which is now TWRP. From there you can flash some ROM.
Alternatively you can get ffactory firmware and flash it with fastboot (that's actually a better option to start with).
I hope that helps

Thanks for the help, but unfortunately, I think that the phone is junk. My phone can't get into boot-loader for whatever reason, and I heard some people post that the phone was designed to make the boot-loader non-accessible. I already tried to flash it with ADB while it starts up, but no device is detected (no USB debugging I guess). So unless I can flash the phone while It's on the LG logo, I can't do nothing.

Please help

I am having a REAL BUGGER of a time with my Xiaomi Redmi Note 3 Pro (Snapdragon)!
1. It is not recognized by ADB in Fastboot mode.
2. I suspect it shipped wit a vendor ROM, and I'm trying to flash latest Official MIUI Global Dev (Marshmallow) ROM, but I keep getting errors in MI Flash (screenshot attached).
3. I want to Flash TWRP, BUT ADB isn't working, AND I cannot get to the download page for the cracked bootloader.
4. Seriously considering Resurrection Remix ROM, instead, but most of the above issues still apply.
I am NOT new to custom recoveries, flashing ROMS, ADB etc, BUT I am dealing with a new PC (Windows 10 Home, 64 bit, like my old (dead) laptop), and I'm new to this device.
PLEASE HELP. (Quite frustrated)
Fastboot won't recognize adb commands you have to use fastboot.
What you can try is booting into emergency download mode and using my flash to flash it from there. I think it's " adb reboot edl" while the device is on with USB debugging or using the mi updater app ( tap the three dots I think).
I think that this is not the correct section for your question, and i dont know the procedure that you follow but try to follow this procedure:
-Connect the phone at pc with USB cable
-Make sure that debug mode and OEM unlock was abilitate in dev settings
-Copy twrp.img in adb folder
-Shut down the phone and press power botton and - vol buttons for enter in fastboot mode
-Run this commands by terminal open in adb folder
fastboot devices
-If fastboot recognize correctly the device run this command
fastboot fash recovery nameoftwrp.img
-After reboot the device with this command
fastboot reboot
When the phone reboot press immediatily vol + for enter in twrp
Good luck
GOT IT! FINALLY!
-I finally got ADB to connect, and was able to enter EDL through ADB.
-Re-downloaded ROM from web.
-Re-extracted.
-FLASHED SUCCESSFULLY!
-SETUP COMPLETED SUCCESSFULLY!
-YAY!
(I think the original download was corrupted, somehow.)

Can't access recovery after 7.0

Hey there!
so, I just upgraded my z5c from MM CyanogenMod to this nougat ROM > [ROM][7.0][Stock][.33][3.7 b7][Deodex][DeBloat][Font][Stereo][Vulkan™] Xperia Loop™
Before the update I could enter TWRP without any problems.
Now, everytime I try to boot into recovery the phone simply reboots...
Things I've tried:
• Typed "adb reboot recovery" on CM
• Downloaded TWRP App to re-flash and click on "recovery reboot"
• Power up phone holding Volume Down
The phone is rooted with SuperSU.
The main reason I wanted to regain access to recovery is to re-root the phone with Magisk.
Thanks for your time.
1. install fastboot and fastboot drivers on your pc (if you don't have them obviously)
2. plug the phone into the pc using the usb cable while holding the volume + button (this way you will skip the adb part)
3. wait for the notification light to go blue
4. go into the fastboot directory
5. download the twrp "recovery.img" file and put it into the fastboot directory
6. hold shift while right-clicking into the directory where fastboot is
7. use the option to open a cmd into the directory
8. type in "fastboot boot recovery.img"
if your phone's fastboot drivers don't have signature (like it happened to me) download Zadig and create a signature for the driver
Hope this helps... i had the same problem and solved by doing this
