[Q] [failed to boot 2] How i do ? - Atrix 4G Q&A, Help & Troubleshooting

Hello everybody !
I wanted to install a new "ROM" on my device. I installed the "ROM" with "RCW" and everything went well.
But when I turn on the device again, the following message appeared:
"Failed to boot 2"
"starting mode rsd"
What should I do?
I tried to reinstall a "ROM" in "SBF" but the process to stop after a while and says "failed".
I also tried with "fastboot". Everything seems to be fine but the device shows the same message.
Any idea? Have i to unlock the "bootloader" again?
My device is an "AT&T" from "United States" and used in France. The latest version of "android" that I used was the official 2.3.4 updated "in the rules" with Motorola.
I just wanted to install a "ROM" more Sympathic. Until now I had just root the device and unlock the bootloader.
Thanks for all !
P.S: I searched around and tried many things. So I'm sorry if there is a post that I have not seen about it.

If the boot screen shows unlock on the top of the screen than u don't have to unlock the bootloader again.

You should check if you get the "unlocked" message on the top left side of your screen to ensure it is unlocked or not.
If it doesn't show anything, you should try to unlock the bootloader again.
Just be careful to not flash any rom through SBF before make sure you are not downgrading your Kernel version, or you will hardbrick your phone.
The Pudding (http://forum.xda-developers.com/showthread.php?t=1136261) thread and the Brick thread (http://forum.xda-developers.com/showthread.php?t=1160408) should give your more insights about this.
I'm searching for some screens and a thread explaining how to unlock the bootloader in the safest way. As soon as I find I'll edit my post.

Thank you for the answer.
I'm also looking on my side. The first is that the announcement to another.
Thanks again ;-)

[Q] Bootlader unlock problem. Help??

Hi I've tried searching about quite a bit but can't seem to find the correct solution.
I've had the bootloader unlocked once by following DoomLords instrucions but locked it as an upgrade popped up on my pc companion, now I can't seem to unlock it again.
I've followed the same process as before, even through the sony bootloader unlock site (this gave me the same unlock key as before) I've attached my error from the command prompt screen.
Anyone??
the screenshot is not readable.
maybe you forgot to remove the last number form the unlock key.
or flash a firmware first then try again
Sorry here's another screen.
I tried to re unlock the bootloader after an update via pc companion, it didn't work then.
I've now flashed ICS onto the phone with flash tool and unlocking the bootloader still doesn't work.
I've tried taking the last digit off the unlock code, with no luck!
Random post to keep the thread alive, hopefully someone will know whats up
Last try, anyone?
You're not using 0xFFFFFFF as the key are you?
No definitely not. That was the error the 2nd time round trying.....

Bootloader doesn't exist on Nand........

Hallo to entire forum,
I have a phone called Y9190 that suddenly turned off and will not turn back on. I tried to flash it with flashtool, but the program sends me this error: "Boot Loader does not exist on NAND / eMMC flash! Please download bootloader first."
At this point, I do not know how to go forward.
The flashtool drivers are installed correctly and the rom is the right one.
Any idea to help me?
Thanks in advance
Any suggestion is welcome.....
Same problem
I googled it and many of the answers are opening your phone and unlocking your bootloader, but how?
The phone is dead and won't open...
I've got the same message "Bootloader doesn't exist on nand flash. please download bootloader first..."
UP FOR THIS!!
They most likely removed the bootloader. This is not uncommon with some China based knock off devices.

HELP please... HardBrick RN3SD

i don't know what to do... i think i read every tutorial for unbrick my phone but nothing works...
my situation:
-i unlocked my fone by unnoficial method, instaled twrp and everything was ok.
i decided to instal sMIUI, but nowhere i read that is necesary to delete emmc file... so i bricked my phone.
bootloader got relocked, i can't turn on my phone, mi logo appears during 1 sec > screen off > again mi logo during 0.001s > screen off
when i plug in my phone into my pc, i have black screen and red led, but it's not adb mode.
i can't enter adb, my pc (windows 10 x64), i use command "adb devices" and list is empty
i can't edl
i can enter in fastboot mode.
i can't flash nothing, "failed: device is locked"
anyone can help me?
if i unlock officialy my bootloader, can i flash again stable rom or something? i just had my phone during 2 weeks.
can i do anything?
thanks.
one more thing: i had guaranty, so, if i unlock my bootloader officialy, i lose it?
i don't want to try testpoint method, because of guaranty.
Well, welcome to the party.
Irrespective of how much u search, cry for help or open millions of threads like this instead of doing a little search, there is no solution except test point method. Now don't ask how to do it. Search and read a little u will get the necessary info.

thanks a lot for this kind help, i will do it, don't worry. :good:
Don't worry bro u will certainly do what is required. I was the first who reported a bricked device while unlocking bootloader by unofficial method. After extensive search and trying different methods I came to this conclusion.

TF201 Unlocking Issues. "Device is unlocked" when using app, but not on boot

TF201 Unlocking Issues. "Device is unlocked" when using app, but not on boot
Hello everyone!
I'm unfortunately stuck on step 3 of this guide for getting katkiss on TF201: https://forum.xda-developers.com/tr...uide-tutorial-asus-transformer-prime-t3486237
I was able to upload the apk for the unlock_device_app_v6, and install it, but when it comes down to 'press to unlock your device', I originally got "Failed to unlock device, please try again later". I've tried multiple times to no avail.
I decided to remove my SD card, and try again, and (maybe by pure coincidence), it now says "The device is unlocked" when I click on the 'press to unlock your device', however, there was never a reboot, or a restart.
I decided to continue, but I'm unable to fastboot the flatline_tf201.img file (failed remote invalid state), which I guess means I don't have the bootloader unlocked. When booting the transformer prime, I don't have the text in the top left. I've already factory reset. I have not rooted.
Any advice? Am I missing something?
Thank you
Same problem
Hi!
Did you get any help for this? I have exactly same kind of problem and I´m totally stuck with it.
Thanks for any help

(Trackfone) Alcatel Tcl Lx [A502dl] : Help unlock bootloader & rooting

As in the title, I have an, Alcatel Tcl Lx A502dl, Android phone, originally purchased from Walmart with a Trackfone Sim card (Now there is no sim card insterted).
I have spent all day, up until now, figuring out how to link abd and fastboot to the phone using USB debugging, and I have been successful this far. I had downloaded latest "platform-tools_r29.0.1-windows" from here on XDA, and I downloaded latest "fatsboot" from "HighonAndroid.com", for a quicker experience, without wasting time and effort on Java downloads. In addition to all this, I let the computer search the network for updating driver software, for my Alcatel phone. I also downloaded "UniversalAdbDriverSetup", from the former link, @highonandroid.com.
I linked both file pathways for corresponding "Fastboot", and "platform-tools", into the environment variables, under the term: "Path", yes, using a ";" with no spaces to add the new pathways.
I had success linking my phone onto the "abd" program, the phone is listed under "abd devices" command. I could not seem to get a listing of my phone serial number, under the "fastboot devices" command?
I have tried to get "platform-tools" to put the phone into "fastboot/bootloader" mode, but the phone simply reboots, back to the lockscreen. I have also tried on "Fastboot", to "fastboot reboot bootloader", and my Alcatel again reboots to the lockscreen. All the while, I activated the OEM unlocking switch/setting in the "developer options" of my phone, from the beginning, before I ever gave any commands?
Why won't my Alcatel phone reboot into the "fastboot/bootloader" screen, where I could command "fastboot oem unlock"? Why does my phone respond to both programs, yet still she loads the lockscreen?
I am new to all this, not really a tech savvy individual, just wanted a liberated operating system for my line of work...
I need bootloader unlocked in order to root my device via computer, correct?
I can not check to see if my bootloader is unlocked, not by abd tools, or by numerical code in my "dialer app". The app crashes, and any time I attempt the "fastboot oem device-info" command, no device is listed, only a <looking for a device> prompt of sorts appears. I have been told this may be because, the drivers were not installed properly, or the device was not properly connected under some other issue, and I can try to fix this error by reinstalling drivers... what would the issue be?
I need help, and I would appreciate some guidance on rooting my Android, as there are not any threads in the forum, on this model of Alcatel, that I am aware of?
I am doing all of this on a Windows 7 computer, in a Library, just so you all know. I ask for administrative approval for most things.
Thank you.

Temporary mtk- root. Use init.d for always root

I can't possibly express how much I would love for you to elaborate on the 'use init.d for always root' part. Anyone else who knows, please jump in. Start by pretending I am an idiot. Then stop pretending and explain it to me as if I were an adult who needs a full-time minder. First one to help me achieve "always root" on this terrible, wretched, little excuse for an electronic device gets my undying gratitude and um, maybe some Google Play money? I am open to ideas here on that score. To reiterate, need help rooting my Tracfone TCL LX A502DL that has a castrated recovery (seriously, you can't flash anything from adb, the option is flat-out missing) and apparently no fastboot access AT ALL. I could do another seriously in parentheses, but you need to take my word for it w/o a bunch of examples. The bright spot is the vulnerability the device has to the mtk-su exploit. Get a # in like no time at all. Time elapsed from executing the file to getting the prompt is too short for my flesh computer to register (unless you -v, then about 1.5 seconds.) So how do I turn a root prompt into full root?

Thank you, H
Did he get that?
So did he earn that Google Play Store money or was he just full of it?
Just bumping this thread in case anyone has ideas for me. Seems like Alcatel has bootloader mode hidden on some phones. Here's my story: https://forum.xda-developers.com/showthread.php?p=81780645#post81780645
BTW - I am using mtk-su and have root and Magisk via init.d scripts, but still can't touch /system or flash recovery because of
Code:
/dev/block/dm-0' is read-only
which won't change unti bl unlocked...
I never did get her to root. Alas she is a broken phone now RIP. Sorry for the disappointments. But I move on more hopeful. ?
As posted by Viva La Android in another thread about the tcl a501dl:
The TCL A1 (A501DL) cannot be bootloader unlocked. Although the OEM Unlocking option can be enabled in the Developer Options menu, fastboot mode has been made inaccessible by TCL. Because the bootloader cannot be unlocked, it simply is not possible to flash a custom recovery or a patched boot image for systemless root support. System-wide root is not possible due to TCL's secure boot chain configuration and dm-verity. Until an exploit is found to bootloader unlock this device, rooting is not possible.

I have heard elsewhere that it's not possible to unlock the bootloader of a Tracfone. Sorry. But at least we know why Tracfones are sold for so cheap lol

unlock bootloader and root with https://github.com/bkerler/mtkclient
This device cannot be rooted. To date, there has not been a single validated claim of a rooted TCL A509DL. The bootloader cannot be unlocked, preventing root, custom ROM installs,etc.
UPDATE: After hearing from some members regarding the Hydra Tool, and doing a little bit of research on the method, it appears that I was completely wrong on my.statement. Members here on XDA as well as Hovatek have confirmed that the A509DL bootloader can indeed be exploited with the Hydra Tool method, opening the door to systemless root with Magisk. Thanks guys for the info and guidance. I have one of these devices and look forward to unlocking & rooting soon. Thanks @PrivyetCyka for the info.
Yes it can .. it was extremely easy to do so also..i have a rooted one in my hand as we speak the only issue is I was stupid and tried to flash the magisk zip in twrp and it set off secureboot so in working on fixing that .. but .. if you just use MTKClient you can pull the entire firmware , magisk patch then reflash the boot.img using the same tool and you can even install twrp I have the entire firmware , twrp, and magisk patched boot imgs for the device saved ,. If someone knows how to disable secureboot I would really appreciate it

I sure would like to give it a whirl, but I haven't had that phone in over a year
Anyway, I decided to stop buying devices made deliberately less functional by their manufacturers.

I stand corrected on my statement. I was incorrect. Out of curiosity, does the Hydra tool require the dongle in order to unlock the bootloader?
@PrivyetCyka send me the Magisk packed boot image and I will unpack it and disable secure boot. I can then pack it back up and link it to you. Are you referring to only secure boot or also AVB 2.0/dm-verity?
I didn't use hydra tool I used MTKClient from GitHub and did an entire system read back to have a backup then just renamed boot.bin to boot.img used magisk to patch it and then used the same MTKClient tool to reflash it... I have a twrp I made for it also but I don't know how functional it is as far as flashing things and backups , the only thing I tried to flash was the magisk zip just to see what would happen and that tripped the secureboot , I used the mediatek secureboot tool and it says it's disabled but it's still not booting past the secureboot fail screen.. when I get home I'll get the files and upload them tonight
