[Q] Motorola XT720 stuck in Bootloader - Android Software/Hacking General [Developers Only]

After i used "basebandswitcher V4 multilanguage V0.6 (07.06.2011)"
on my XT720 my device is stuck in an endless Boot screen loop. Here's a list of things i have tried thus far to no avail:
Go into recovery mode and:
-Clear Cache
-data/factory reset
Flash Rom with RSD Lite with 3 different versions:
-Cincinnati Bell TR_U2_04.1E.1
-Korean Motoroi XT720 2.2
-UK_STR_U2_01.1E.0
Boot Phone without SD Card
Pull out battery for 24hrs and boot phone(with and without SD Card)
I'm not sure if theres a way to get into the phone's files to try and change them because I'm sure that on boot it tries to boot but when it tries to enable the phone modem it has an internal error. On the device screen the only thing i get is the black background with the white "M" Motorola logo in the center. The screen then shuts off and restarts the "M" logo.
So what I'm wondering is if anyone has any other ideas to give me to try. I'm definitely not a veteran with the Android Platform and I've only had the phone for a fiew weeks but i can figure pretty much anything out (usually)
To everyone willing to help, thanks allot.

[Q] Motorola R2D2 Droid Stuck on Motorola Logo

I recently installed a theme on my R2D2 Droid. However, it must have been the wrong version for my droid (I'm new at this ), and thus caused Voice Commands to crash horribly, spamming the window nonstop. I reverted it back to factory settings via the recovery window, however, this only ended in a bootloop of the R2/Star Wars animation. I restarted the droid, and was taken to the Clockwork Recovery Mode screen. I reloaded my backup from my SD card like I had planned too, but my battery apparently wasn't at full, and it crashed during the loading. Now the droid is stuck at the Motorola logo, and refuses to take charge.
Recovery mode and the Bootloader still work, though after resetting the droid to factory settings, I'm still back at the Motorola loop. I assume this is from the lack of a battery charge.
The Bootloader also gives the message
"BATTERY LOW
CANNOT OPERATE".
I'm not sure what to do at this point. I assume that since I can reach both the recovery screen and bootloader, my phone isn't bricked, but as I can't take charge, I don't know what to do.
Any help would be appreciated.

Huawei U8110 - Boot Loop + Cannot boot into recovery

Hello everybody.
Although I've been following the forum since longtime ago, this is my first post. I hope this is the beginning of a more active and regular participation . Once I've introduced myself, I'll explain my problem:
I've got a Huawei U8110 from Movistar which seems to be in a boot loop as it gets stuck at the Android logo screen. I got it from eBay and it was already in an unusable state. I knew that but I thought it was a good opportunity to make my first steps in this amazing world.
After surfing the Internet for days and reading tons of posts to document myself, I decided re-flash the phone . I tried several stock ROMs (Yoigo, T-Mobile and again Movistar) and I was able to flash them without problems from an SD card. However, I got always the same result with all of them, always stuck at the Android logo. For info, when I bought the phone, it had the original stock ROM from Movistar.
As I've said, I've got no problems to flash the stock ROMs from a SD card. I can also enter into the bootloader mode. Nevertheless, I cannot boot into the recovery mode because after pressing the keys combination "Vol up + Call + Power On", I get into a purple / magenta screen where I can do nothing.
I've tried to root the phone and flash a custom recovery from bootloader mode. Through the rooting process, I can flash the image OK with fastboot tool but at the reboot time, I come again over the boot loop at the Android logo. Same thing for the custom recovery… I get to flash de recovery image but if I try to boot into the recovery mode, I get again de purple / magenta screen.
I'm a bit lost and I don't know what else can I do… Any help would be really appreciated.
Thanks in advance.
Regards.
EDIT:
I've forgotten to comment that if I enter "fastboot getvar all", the result is only "all:" without any variable output... Maybe the bootloader is corrupted?
you can try odin? find the pit and flash a new boot loader.

[Q] Boot issues after installing CWM recovery

Hey there XDA! I thought I'd root my P920 a few days back, which went smooth, no issues and I was enjoying my newly rooted Optimus
I wanted to get a new kernel for it, so first thing I did was install CWM, Then clicking on 'Flash ClockworkMod recovery' in the app, which then flashed a CWM recovery if I'm not wrong. The final thing left to do was rebooting into the recovery, which I did by clicking 'Reboot into recovery'
Now waiting for the phone to reboot into recovery, the LG logo came up on screen, and stayed there for some time, which is normal behaviour as it takes a bit of a while to boot up for me, but then something odd happened, the logo disappeared and the screen blacked out, leaving the phone off. Immediately noticing this, I tried to boot the phone up as I normally would, but again the same thing occurred, logo appears, then phone blacks out and returns to an off state.I repeated this a few times, but to no avail.
These are some things I tried:
Normal booting multiple times
Normal booting after battery pull
Normal booting while charging
Normal booting after removing SD card (this resulted in a blue screen appearing after the LG logo on bootup, though I was impatient and didn't wait to see what would happen so I pulled the battery out )
Normal booting after removing SD card and then battery pull
Normal booting after removing SD and SIM card
Normal booting after removing SD and SIM and then battery pull
Booting into recovery multiple times
Booting into recovery while charging
Booting into recovery while charging
Booting into recovery after removing SD card and battery pull
Booting into recovery after removing SD card
Booting into recovery after removing SD and SIM card
Booting into recovery after removing SD and SIM card and battery pull
So as can be seen I've tried tons of situations
A few times, the screen turned into repeated patterns of static colour, it's difficult to describe but its only happened a couple times, and appeared on top of the LG logo. From what I've gathered, something is preventing the phone from booting up properly, either normally or into recovery, unless the problem is something else entirely. Also I don't have any NANdroid or Titanium backups.
So my questions are, could it be that I need a full charge for it to boot properly? Otherwise what's the problem and how do I get the phone to boot normally? I would prefer that all data on the phone is not erased but if it's a must then so be it.
I really appreciate any and all help I can get here, thanks!
P.S. I'm new to rooting and customising at that level, so please ask for any additional details or anything I was unclear about. Apologies to all for the lengthy first post, thanks again!
AW: [Q] Boot issues after installing CWM recovery
Hi welcome
Girst thing you have to do before flashing or doining something with your phone is a nandroid backup. I do always a titaniumbackup and saved pictures and music manually only for insurence. Next thing, whcich app do you use for flashing cwm?
For your data im not sure if you can rescue that i dont think so.
If i understand it right your are stuck on bootlogo right?
To rescue your phone you can always go back to gb by flashing kdz file with flashtool. Watch here
http://forum.xda-developers.com/showthread.php?t=1540163
But in that case you will loose all your data on phone.
P.S. and next time if you want to flash cwm use os_hackings all in one tool. And flash twrp recovery its better and didnt have so much bugs
Sent from my LG-SU760 using xda app-developers app
I used ROM Manager for flashing cwm, yes I am stuck on bootlogo
Thanks for the help! I'll try out what you suggested and report back here if it works

[Q] DG900 Boot loop

Hello,
I have just got the new Doogee DG900 & I might have ruined it already.
I was trying to be sensible & create a backup of the stock ROM. I followed directions to create a custom recovery using MTK droid tools & SP flashtool but now I think that I am stuck in a boot loop. The screen constantly flashes from black to grey but will not load.
By holding power & volume up I am able to get to a menu that gives me a choice between recovery, fastboot & normal boot but it will not let me select one.
I have e-mailed doogee requesting a ROM that I can flash but no reply & it seems to be too new for any firmware to be on the internet.
Any suggestions?
There has been a bit of a development in that I tried flashing the boot.img & recovery.img that I made when trying to make the backup & after I unplugged it from the computer I was able to turn it on & it booted normally.
I got a message saying the storage was corrupted (not the external SD card, which I had already removed) and would I like to format it. It did nothing when I said yes.
No problems are solved however because when I try to turn it off it just goes straight back to the flashing grey & black screen. The only way I can stop this is by flashing again.
This happens when I try anything that involves turning it off - ie. telling it to restart or trying a factory reset from the settings.
It does mean that I can access it from a pc if there is anything useful I can do to affect it from there.
