Okay so today i decide to root my phone. I heard alot about custom roms and other tweaks that make your phone do all this cool stuff. Well i try and download a custom rom, i did use the droid 2 bootstrap, and i believe i backed up on ROM Manager. after that i went and looked at roms and i downloaded Tanzanite ROM. at first i thought i was in a boot loop and i got scared because i rooted my phone last week and downloaded a custom rom wrong and it was in a boot loop. So when i thought this time it was in a boot loop, i hold X and Power button and get recovery options. i factory reset it then rebooted it, it then started up on Tanzanite ROM. I was quite happy with it, then when i try to look at my apps, they are all GONE ! There is no Market and i have no 3G coverage. I was upset and i dont know what to do. I am scared if i do something it will go into a bootloop or i will be stuck with this ROM forever. I NEED HELP ! PLEASE ! i cant afford another phone replacement. Please help me ! Please, experts, people who had this issue, somebody just please help. Thanks.
You're not stuck. There's always SBF.
SBF is your best friend. And a word of advice to you. ALWAYS find out what kind of recovery is out for your phone before you do ANYTHING like rooting or flashing. For Moto phones, SBF is your friend. HTC has RUU's.
Here is the guide to SBF your phone:
http://forum.xda-developers.com/showthread.php?t=770224
(Be sure to get the RSDlite 4.9 and the latest Moto drivers which you can find on Moto's website)
Here is the SBF file to download:

This will get you back to 100% out of the box stock.
Good luck and let us know if you get it fixed. If you have any problems or questions, feel free to PM me.
I fixed the problem. Thanks guys but i would like to know, what is SBF and what does it do? Everytime i do a new ROM i am scared of the outcome. It bootlooped once and got a new one. I will always be scared when my phone re-boots. Alot of feedback i got, has mentioned SBF and i have yet to know what it does and yet to know what it means.
I could be wrong, but I think SBF stands for System Backup File. It basically is a file that came from Motorola. Motorola uses it to get the phone back to its out of the box state, meaning it returns the phone to the same state as when you got it.
You use it if you have no way to fix your phone. As long as you can get into bootloader mode, you should be able to use the SBF. It's actually pretty hard to 100% brick these phones.
Most phone has some sort of recovery utility like this. For example, HTC has RUU (ROM Update Utility) which will do the same thing as an SBF for Moto phones. I don't actually know what other brand phones have, because I've only ever rooted HTC and Moto phones.
Also, when you flash a ROM, you say you bootloop right? Be sure before you flash a new ROM to wipe data and cache in clockwork recovery. This should prevent bootloops.
first off im not a noob at this kinda stuff ive rooted tablets and other phones before. so ive spent the past week or so every night for hrs searching around for an answer to my problems.
phone info
carrier:Straight Talk
MN: XT555C
AV:2.3.7
Base band vr: PCR
Kernel vr:Apps_2.6.38.6-perf
Build number:1_67D_1014
OK on to the proses i used:
first rooted phone with VROOT
pic 1(the pic with the Foreign letters)
gained root
pic2 (pic with root checker)
easy enough right
then tried 2int every vr of it witch said they installed just fine
but every time i would try to go in into the boot-loader nothing no blue light no auto boot loader screen just nothing.
so i searched for different kinda boot loaders witch lead me to twrp and only like two more
nothing couldn't get any of them to work on account of the fact that they needed a Boot-loader to install them.
then i decided i would try rsd lite
downloaded sbfs
http://sbf.droid-developers.org/umts_jordan/list.php
ive tried the first and last one not sure witch one is for my phone
when i hit VOL+ power i get this screen:
pic 3(white screen with blue letters)
and rsd reconised the phone but phone info came up mostly as
N/A and nothing would flash just kept giving me
error:failed flashing process. failed flashing process phone 0000 error sending ram to bootloader
then when i had the phone try to just boot normaly with rsd open i got this screen:
pic 4(black screen with white letters)
all things aside i have gained root but to no avail can i get a Boot-Loader to work. im just looking for some one to help shed some light on this matter and help me get off of Ginger Bread

Have you tried this: http://forum.xda-developers.com/showthread.php?t=1743764
It worked for me.
i have now tried that and it was useful as far as the commands in the bat file but still nothing i did worked
i unrooted it the wipe cash and factory restore the Zerg Exploit did not work it would not root it so i used the commands to install bootloader it worked with no errors my led turned green to show success but still no blue light or Boot-loader. even when i use
E:\android\adt-bundle-windows-x86-20131030\sdk\platform-tools>adb shell
$ su
su
# reboot boot-loader
reboot boot-loader
it just reboots normally
any one else have some info?
so i still cant get a bootloader to come up ive been at this for a while and am still stumped i gain root and su but no custom boot loader just the stock one.
Root, install 2ndinit, install CM10, install CM10.2, install update-recovery.zip, REBOOT (without any wipe), install CM11 and GApps.
^
so this is just so people can see where im at in the chain of things here. im at the install 2ndinit
nother update so i desided i needed to push the files from bootmenu.tar.gz onto my system and see if it changed anything(also did the same for twrp and a few vrs of other bootloaders)
so i went and got http://forum.xda-developers.com/showthread.php?t=1687590
witch worked well and after i used the program to send the files where they need to be and tryed to reboot into bootmenu the phone still just restarted normally.so now the files are where they need to be adn it should let me into the bootloader but no im at a loss i dont understand how sompthing so simple could turn out to be like this. every one else can get it and ive followed like every set of direction i could find on this site over and over agen then i started experimenting with it and still nothing no matter how the files get there still no bootloader all i want is to be able to install JB and get the hell off of GB. and its not like im getting any help from this post i hope a dev can come by here soon and help me shed some light on things. untill then ill keep updating the post

I don't think the XT555c has a JB or even a ICS ROM. You can debloat GB and stay on it.

ive read thru a few threads other than those also and other people with the same mn and build have done it......
thats from my understanding that they wer able to get a boot-loader to work witch i can not get into a bootloader at all.and RSD wont flash anything to the phone evern tho ive used diffrent vr of rsd and the moto drivers.
so am i to assume that it just cant b done? that i could understand but other people with this phone/67d have done it and ive sent them pms but no reply same with some of the devs here who have helped others get this phone going so i guess im at a loss with this straight talk phone at least with installing a custom boot-loader/ROM.at least the phone works.....just outdated.screw you motorola
just a reply
@jimbob it my feelings that the "USA Moto defy xt555c, Straighttalk" does not have a blue LED built in. There is no evidence of it other than i have never seen one during the last year or so of having the phone (yes i do a lot of bluetooth stuff). Also to shed some light on your situation it is my understanding that 67d firmware has patched an exploit with the older bootloader and now has been upgraded to bl7. if this is your bl ver number then it is slim you will find the answer to your problems here. the only option i can come up with is to get or make fixed sbf for the device and flash/ downgrade. fixing the sbf only lies to the phone and tells it you have a higher ver android than you really do.... go figure motorola would be good at burning bridges! LMAO
thanks for replying. not to sure how to make a fixed sbf and the ones i found would not work because i couldn't get the program to flash anything to the phone. but then agen i never made a custom one
I have had my Maxx HD since launch and unlocked very soon after it became available,
Recently I downgraded from the last OTA with matgroffs 1.21 utility and enjoyed a wonderful clean slate experience but after a while (today) I went for the OTA to get prepared for KK coming soon hopefully, the install failed entirely and my bootloader is now back in a locked state the phone is stuck in fastboot and will not take a flash from any utility on here, 1.21, 1.3x 2.0 ext including rsd lite.(RSD will not even detect the phone)
Ive tried the utilities on Mac and Windows 7, nothing has worked so I broke down and called verizon and ordered a recertified razr HD for a discounted price.
So just a warning there is a way the bootloader can get relocked. will take a picture and load soon to show the screen of the phone incase someone can help. Just a side note my vibrate motor failed and I have been having 4g radio problems before I went back on matgroffs utility.
You tried house of moto to fastboot flash 98.30.1? Sux they found a way to relock them...

This only shows up when you get the GPT error. It will still be unlocked once you get this restored. This came up when the OTA was released. A few people with unlocked BL had this GPT error. There's a fix somewhere around here, just search for the error.

@AndroidGreg
There's a line in the fastboot xml file with gpt_main0.bin (somithing really similar to that, been a while since I flashed it...) and all that's necessary is removing that line and flashing the fastboot with rsd, or just manually flash the fastboot skipping that partition, either or will work and fix the problem. Even though the bootloader is unlocked, that particular partition IS still controlled by securtiy and is blocked from downgrading -- luckily for us the partition table never changed between rom versions so it's perfectly safe to flash or not to flash it.
I've never flashed with RSD, but IIRC, there's also two more lines in the fastboot's xml that need to be removed for it to properly flash. I've only flashed my phone with moto-fastboot from linux and used MythTools from windows -- MythTools is an interactive script for the Atrix HD to flash stock fastboots, root, unlock the bootloader, flash a custom recovery, boot logos, and soon different radios -- Similar to Mattlgroff's tool.
The Atrix HD has the exact same issue with that partition.
download the sbf file from http://sbf.droid-developers.org/phone.php?device=5
install these drivers https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481/action/auth
connect the phone in fastboot mode.
now extract the "fastboot_rsd.zip " to a folder.
extract the contents of the downloaded sbf/xml file into the fastboot_rsd.zip folder
execute "flash_fastboot_erase_userdata"
worth a shot.
always works for me..
good luck.
RSD does not detect the phone at all, only the quick utilities did and they failed. Verizon overnighted my new phone and its here already, not unlockable im just gona root and keep it for a while till I switch to strait talk with the nexus 5, I cant afford $100 a month anymore anyway.
First off, thanks to the OP for posting this. This was exactly my thought on getting the KK update when it arrived then building phone back up with the mods and apps I have currently - flash back using 1.21, update, use TiBu to reinstall everything. Sux to see that didn't work, but thank you for posting the warning to others.
Not that I'm hoping to see others attempt this and fail or somewhat ruin their phone, but has anyone else had this experience? Anyone verify this method isn't possible to keep unlocked bootloader and a fully working device?
If not possible, hopefully someone will build a flashable version of the OTA KK update when it FINALLY arrives. I'm way too unstock for the update to work OTA, that's a fact.

It only shows that his BL is locked because of the GPT error. I can assure you it is still unlocked. Many, many people updated and we still have unlocked BLs. Heck, I've flashed the latest OTA on my M and HD with RSD and am still good. He just needs to fix the error, but he have up and got another phone.

Exactly. The Atrix HD gives us this error if we flashed the stock Mexican firmware (our latest) and try to flash anything below it, or the Bell firmware (2nd newest) and anything below that, and so on and so forth. All that's necessary is to remove the gpt flashing line and go again....just like we have to remove the oem lines from the fastboot xml.
First time I had that error, I went WTF (the first flash after unlocking my bootloader if ya'll's curious), knew that GPT is a partition table from grub experience, figured that the partition table has never changed since stock ICS roms, removed the GPT line, flashed ICS, and I was happy.
I'd love to be able to combine all the data, system, cache, and any other partition that don't need a fixed place (like modem, etc) and be able to use ZFS or BTRFS volumes to maximize the amount of storage we can have -- I've always wondered why they don't do something like that already...
Ok 3 computers 1 xp and 2 windows 7, nothing, mac nothing, even made a factory cable because the battery just got to low, nothing, no computer will detect it, using any of the 3 motorola branded usb cables plugged directly into the laptops. Now the utilities from matgroff and the other guy (cant think of his name but he made the 2.0 utility) will not even try to flash the phone they say please plug a phone in that is in fastboot mode, I
Serious question, but have you tried Linux? My old Bravo wasn't detected by Windows (XP or 7, been 2 years now) after a bad RSD flash, but I was able to manually flash it from Linux (either Manjaro or Debian Testing). After that, to this day it'll flash with RSD, but it isn't detected properly. I still flash it, and almost everything else, from Linux because I don't trust flashing from Windows anymore. I made an exception recently to help with a tool and because my Linux partition was down for a month.

I tried doing the exact same thing as the OP - factory reset to "stock" and then flash back up in preparation for KK, after using TiBu to save everything and using SafeStrap to make a Nandroid (very thankful I did). I ended up with the identical screen that the OP had, even stating that my previously unlocked BL had been apparently "relocked." For me, RSD Lite did recognize my phone (I updated RSD to the latest version beforehand), however it would not flash anything for me (the flashing process would start and then immediately say "failed").
See my post for the details and the solution I used: http://forum.xda-developers.com/showthread.php?t=2674431.
I was completely freaked out for a couple of hours until I stumbled upon bweN diorD's GPT partition fix. And then everything was fine for me.
Hope this helps anyone who falls into the same trap.

I had this same problem when i tried to go back to stock a while back. You need to flash the gpt_main0.bin file to fix it. Here are the steps I used to fix the problem: http://forum.xda-developers.com/showpost.php?p=47716278&postcount=57

@AndroidGreg, do you still have the phone?

This is my first post on XDA and i am in desperate need of help. I own a Asus Zenfone 6. Recently i tried unlocking bootloader and installing TWRP recovery so that i can flash a custom ROM. It went horribly wrong and i bricked my device. I managed to unbrick it and revert to Stock ROM which i also upgraded to LOLIPOP using adb sideload. I also managed to root it and have super user access. The problem is that i cannot install a TWRP or any other recovery. When i try to install a custom recovery i get and error " cannot install unsigned image on secure device" which probably suggests that the boot loader is locked. I ran the commands to unlock the boot loader and they ran successfully but i am not sure if the bootloader is locked or unlocked.
I tried running fastboot oem devices but i get an error " Unknown Oem command".
It was after hours of troubleshooting that i decided that i am OK with stock LOLIPOP rom as long as i have a rooted device. It was after sometime that i noticed that the camera wasn't working. Also the flashlight wasn't working. I uninstalled the updates and flashlight was working. However the camera just gives me a black screen for some time after which it quits with an error message " Camera is used by another application. Please reboot your device and try again". I uninstalled the updates for Camera and reverted to a previous version by also removing the camera application using super user access. However for an older version i get an error " Camera not found". I have also tried installing other camera applications but none seem to work even after making them a part of system. Currently flashlight works but only under an older version , as soon as i update it stops working. I decided to lock the boot loader again as it was just not worth it. However after running the commands and locking the bootloader i still cannot get the camera to work. I tried in safe mode and the camera won't work there either.
When i go to recovery i just have four options, there is no install from internal storage or SD card which suggests i am on stock recovery.
Currently i just want my camera to work. I am OK with the stock ROM and recovery as long as i have a rooted device. I have spent hours researching and nothing seems to work. I am in desperate need of help. Some of the friends suggested to try my luck here. I would be indebted as i dont want to purchase another device just because i screwed my camera. Also when i was under kitkat i ran the SIMI test and was getting an error 1667 and 1668 for both cameras. The test is failing under LOLIPOP as well. I dont think its a hardware issue or maybe i am wrong. Any help would be appreciated.
Thanks.
Not even a single reply. DISAPPOINTED!
You need to Lock Bootloader then reflash the rom (wipe all) to fix it. Custom ROMs sometimes cause camera not working cuz there are some devices that have different camera.... Next time, just make sure you Lock Bootloader => Flash Stock recovery => Wipe => Flash Stock ROM

But yeah that sounds like a roller coaster.
Just picked up the Zenfone 6 to see what I could do with it, I'm going to try to flash the RR rom on here.
Just something I noticed though, I did some research myself, and a couple of sites like this one (https://zenfones.gajetzki.com/) say that you should root your original stock before doing anything. Now this wasn't a requirement at all in my experience for all other phones so I'm a bit skeptical. Anyway I thought that may help in some way.
Good luck!

Sorry for the late reply, but I'll try to help as much as I can. First things first, I know there are two different models of the Zenfone 6, the A600CG and the A601CG, but apparently this shouldn't make a difference, but it could have in this case, after all they must have different names for a reason. Also, the support for the Zenfone 6 is pretty terrible in terms of custom roms and the such, so you may even be better off with the stock experience, just root it and you'll have all the functionality you could ever dream of.
If you're still keen for the custom roms and stuff maybe check out this thread:
https://forum.xda-developers.com/zenfone-5/general/recovery-twrp-2-8-6-0-asus-zenfone-5-t3136263
Other than that, I guess Google is your friend, but so are we!
I haven't been able to hold onto my Zenfone 6, as it was a friends, so I no longer have it and never got the opportunity to have some fun with it, so I'm just going off my own experience with my HTC One M9, which is probably vastly different, but I suppose the process isn't too different. Nonetheless, I hope all goes well!
I'll put the long story below..but spare those that don't want to read. The short is, I'm not able to ADB Sideload the OTA images as it always fails to verifiy signature at about 40-47%. I've searched many places and not found a fix. So I'm hoping the genuises here at XDA which I frequent can help.
The long story. I've flashed roms for many years. My current device was the Nexus 6p. Running XE Rom I think it was. Flashed an update all was well, but my sim card would not show up. I was on MetroPCS and remembered needing a different radio. Flashed that,still no sim. Decided I'd go back to Stock since those had been updated to 8 by now. Flashed the OTA and followed some steps by another thread on XDA, one of the last was locking the bootloader. I had not booted up so I didn't know if my system was working. My big mistake! I locked my bootloader and don't have a system to boot into so I can enable OEM Unlocking. So now I only have adb sideload, can't flash individual images through fastboot! I think it can be recovered but for some reason the signature verification issue keeps coming up no matter what cable or PC I use.
If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

If anyone has any thoughts I'd love to hear them. I have since moved to a Hauwei Mate SE and am pretty pleased but will not be a flashing phone I don't think. I loved my 6p and it still had lot's of life for me. I hate to sell it for parts at this point.... Thanks for anyone willing to chime in.

First, if i understand right you tried to flash OTA over custom rom to return to stock?? To go to stock you must flash full system image, not OTA.
And second, why the hell did you lock the bootloader??...you dont lock the BL unless you are 100% stock..
I know i didnt help you much, but if your BL is locked, dont know how to help...maybe someone else know how to unlock it again
Meanwhile read this guide,it will help you to understand some things:

Oh believe me my head hit the wall for sure! I got careless and wasn't thinking straight. No reason to lock the boot loader except it was on a list of steps to get back to stock..and I guess it was late! doh.
There are lot's of posts/videos I've seen that should allow what I'm trying to do with sideload adb but mine keeps getting a signature verification error. Each new full version of a release 7.0 8.0 etc..has the entire rom, images etc. So your suppose to be able to flash those even though they are OTA updates... *shrug*
It's a blur what I did exactly in some areas. I at one point may have tried to flash the set of Stock IMG files as well. But for sure now all I'm left with is a locked phone with who knows what on it! Stock recovery...some form of 7.0.0 that has NYC as letters...that I can find NOWHERE! on any official releases...
Prob trash, I really want that night back..lol.
