I had flashed my Motorola XT5 (Z71 variant) to CM 7.0.3 and installed CWM Recovery 2.5.1.3. Everything was going smoothly since 17-Oct-11. I used update-CM-7.0.3-Z71-signed.zip to updated using ROM Manager 4.5.0.1
I installed a few apps from the Market yesterday & they were working fine. Total apps installed = 128. I switched off the phone yesterday night.
This morning, when I switched it on, the Motorola Logo appeared followed by the CM7 Splash Screen (for a little while only). Then the screen went blank (slight glow in the background) and remained like that for several minutes. No buttons working incl. Power. Had to reset the phone by removing the battery.
Tried to boot into recovery by holding 'Camera+Vol Up+Power' buttons. Motorola Logo appears with "Enter recovery" written across on top. remains in this screen for several minutes. Had to again reset by removing battery.
Please Help! I can't seem to figure out what to do. I have a fairly good tech skills. Will follow steps if you're kind enough to guide me. Please.
Enter fastboot
Use it to install the custom recovery.
What is the key sequence to get into Fastboot on Motorola Xt502?
What should I do once I get into Fastboot?
Please guide!
TIA
It's
endcall vol down power
But you need some tools to install recovery.
Other solutions use [SUT] to refresh the firmware '*. nbo'
I had the Photon Q with the SIM mod and CM 9 working for 2 mouth. But yesterday, I were using the cellphone when it reboot itself and get freeze on the unlocked bootloader warning. I try to power it of but y could not, the I let it there until batery drain (about 4 hours)
Now when I boot the cellphone it has an strange behavior. Some times it freeze on the unlocked bootloader warning, other time make a loop boot (show the warning and restart). Also some times it display strange colors on the screen when try to boot and many times it display a randomly sorted grey vertical lines and very few times (one of every 50 times) it boot the ROM but when i touch the screen it goes black.
i can not conect to phone by adb and can not enter recovery, but i can access to the fastboot (in fact the fast boot is working but do not display anything on the screen, i suppouse that the same happend with the recovery. but i can not use it if the screen is black)
I used the fastboot and RSD to flash the stock firmware, the phone return fail on every 4.0.4 ROM but it work with the 4.1.2. After the flash some times thes phone display the morotola and sprint logo and then start the handfree configuration, but when I touch the screen it goes to black again.
I do not know if it is bricked, I think that if i have access to the fastboot i can resurrect the phone. but is very strange the random behavior.
Do you have any idea what should I do?
Thanks.
PS: sorry for my bad english
Re-Strange behaviour
Hi there, one of my Q's (also sim modded) was doing a similar bootloop warning etc. I was screwing around with it a bit. It's all good now though.
The way to force power down/reboot is to hold "volume -" and the power button for 10-15 seconds. If you drain the battery, you will be stuck with more boot-loops due to a flat battery. If you plug the charger in & the LED is green, this means it is charging a dead battery, & will need to charge for a while.
By the way, I had issues on my other Q handset running CM, failing to read the mSD card, and causing freezes, boot loops etc, so I went back to stock. Pretty sure most of the trouble is due to the mSD card read/mount error.
Edit:
Come to think about it - my Q failed after I tried to restore my CM10.1 backup from the previous phone. I suggest this may be contributing to the issue, as you are also running CM.
With the black screen/boot loop, force reboot by holding "vol -" & power button for 15 seconds, release power, then immediately hold "vol +" so it forces boot to recovery (TWRP if you have it).
I restored a previous backup eventually, but TWRP was not working too well after the screwy boot-looping etc. I ran a factory reset from the phone menu once it was running again, then rebooted into TWRP.
Super User wouldn't install from TWRP after, so I pushed it across & installed from TWRP, now I'm about to update TWRP to 2.6.
Still want to have a go at another ROM on this handset, so I can compare it to my stock one. I'm pretty sure CM10.1 was part of the problem on the other Q with my mSD card failing, as it has been fine ever since on stock.
Try this:
Try using adb to fastboot into recovery, then push TWRP (again) onto your Q using this method by arrrghhh http://forum.xda-developers.com/showthread.php?t=1887070
Push Super User across onto your mSD & install that from TWRP as instructed also.
Restore a stock/custom backup from an earlier time if you have one, or flash a fresh download.
Let me know how you go.
P.S. make sure you have "USB Debugging" enabled in developer options in order to ADB fastboot recovery.

I tried it, but do not work.
I flash the stock ROM from fastboot and also flash several recoverys, but never boot any ROM and I think that i access to the recoverys but the screen is black then is very dificult to use it. Is strange beacouse some times screen displays perfect the unlocked bootloader warning, but never display anything on the fastboot or the recovery.
Witch part of the software have the video drivers that are used on the recovery and fastboot? I think that maybe is corrupted. how can i flash it again?
Thanks.
Hey guys, I've got a Kyocera Brigadier and I decided to change the runtime from Dalvik to ART. Now the phone is stuck on loadscreen and I don't know how to fix it. The phone is rooted using the KingRoot app, but I don't know if that would help in any way.
Please help me guys!
Similar Issue
I am have a very similar issue, I also rooted my Brigadier with Kingroot and all went well. However, I attempted to flash the Xposed Framework onto it using Flashify. After doing such it got stuck in a bootloop, I was able to fix that problem by booting into fastboot mode and using fastboot to push stock firmware back onto my device. However now I have an even bigger problem where my phone boots up to the Powered by Android screen and then to the Kyocera screen, however instead of continuing to boot to the Verizon Wireless screen and then into the phone, it gets stuck at a black screen. I have tried waiting for hours and nothing at all happens, also I can no longer seem to boot into fastboot mode or in other words the Powered by Android screen with the little 1 in the top left corner of the screen. Fastboot nor ADB recognizes the device when plugged into my computer, as neither list anything when ran. Please help, I don't want to have to pay and end up sending my phone into Verizon to be unbricked.

I have the same problem. I bought a new a Brigadier that was on 4.4.2. I rooted with Kingroot ran update and now my phone will not boot past Kyocera screen. It goes black with the back light on. Did factory wipe and still nothing. I am shocked that KK has killed yet another phone of mine. I very much dislike KK ROM. What did you find out?
Hey guys,
I have an issue with my Iron Pro, basically I turned off the phone one day, went to turn it back on and the UMI logo showed for 2 or so seconds and the device turned off again. I can access the bootloader but the same issue occurs when selecting recovery. I have tried reflashing the device several times with different roms (custom and stock) using SPFT with no success. However, after leaving the battery unplugged for a long period (3 or 4 days?) of time the device booted so I thought it was all fixed, went to restart and... guess what happened. I can't use fastboot to reflash because I don't have a custom recovery nor when I do flash one it still doesn't work. I believe it may be a hardware fault at this point. Any help or advice would be appreciated. Cheers
Hi, i unclocked the bootloader and flashed updated to Android 11 on my A51 few weeks ago and everything was going fine until yesterday i plugged it into charger and after a few minutes when i tried to unlock the phone, the screen doesn't show up. eveything's black. i tried forced restart method and other possible methods but none worked. the display only shows samsung logo while restarting and while in recovery and download mode but once it restrats completely, turns black again. i thought relocking the bootloader will do the job so i go to download mode and select LOCK BOOTLOADER( i didn't know if it was correct as i have 0 knowledge regarding these). and then it's stuck in download mode and no methods worked to get outta it.after a few hours, several while vertical lines and then blue dots(in the corner and surrounding the fingerprint sensor) start appearing on the screen and increases gradually with a break. however, i was able to install the custom firmwire (android 10) {although samsung officially released android 11 on A51s} using odin and then wipe the phone completely but now it restarts and then back again on the black screen. what can i do now? thank you
