Help! I need to get back to stock rom on droid bionic!

Dear Sir/Madam,
Before Spring Break, I rooted my droid bionic using motofail for windows. I do not know what the software version is, but I will include the software (motofail) in this email. On Thursday March 28, 2012 I decided to try installing ROMs to my Droid Bionic. I saw that Liberty Rom, Blurr3d Rom, and Eclipse Rom were cool roms. so first, I got Bootstrap (I will include it in this email) Bootstrap is a .apk file. I also got ROM manager, titanium backup, and one more, but i do not recall what it was. I made a backup of the stock ROM with ROM manager. and i installed bootstrap. little did i know that if something bad happens to the phone during a ROM install, you cannot restore a previous backup. So i cannot get my stock ROM back on. later on, before i had a problem with bootsrap i installed liberty ROM. then i got board with it then got blurr3d. then i got eclipse ROM. that's when i started to have problems. After i installed the eclipse ROM, noticed that i could not get any cell service or data service. I could get data from wifi though. So i freaked out and got liberty ROM. i read up on it and someone said i should get safestrap. Safestrap is like bootstrap but it is safer because you can access the recovery menu from boot and not have to access it through an application on the phone like with bootstrap. So after i got safestrap i installed it, rebooted it and made a back up. Before i made the backup i put plurr3d back on becasue i thought that the radio files from eclipse were not compatible with the radios on the bionic for some reason. This was all on Thursday. well, this time, it took 3-4 hours for blurr3d to get passed the welcome to andorid please touch the android to continue screen. on the screen it said, "please wait... this may take a few mins" after about 20 mins i got worried so I pulled the battery and rebooted the phone. and got back to the same screen. After i got back to the welcome to android screen, i had to go to football practice and dinner afterwards. when i got home, which was 3-4 hours later, I checked on the phone and it was past that screen and i was able to add my gmail account to it. For some reason or another, the cell and data services were not working. so i left it at that for a day or so and on Friday, I tried using what a lot of people are saying on the Internet which is, RSD lite. you can use RDS lite to flash a stock ROM onto the droid bionic. at that point, i thought that if i got the stock ROM back on, the radios would start working again. well, when I put the phone into fastboot mode it said,
AP Fastboot Flash Mode (S)
0A.61
Battery OK
OK to Program
Connect USB
DATA Cable
It also said the same thing when i connected the USB cable to the phone and the computer. RSD lite did not recognize the phone so i tried for a couple hours with the same result. Later on, I read that restarting the computer with the phone in AP Fastboot while the phone was plugged in would get the phone to say,
AP Fastboot Flash Mode (S)
0A.61
Battery OK
OK to Program
Transfer Mode:
USB Connected
This worked, but RSD lite still would not recognize the phone. So then i remembered that i had a stock ROM backup with bootstrap and i did. so i un-installed safestrap (one of the worst mistakes i made so far) and installed bootstrap. so i booted into recovery via bootstrap to restore to stock ROM. things did not go as planned... for some reason or another, it booted up normally. without going to recovery. then it wont to the dual core screen then the bionic eye screen with someone's ROM underneath it (it didn't say someones ROM but it said some one's name then the word ROM) then blurr3d ROM booted up and it kept crashing. so i ended up staying up to around 2-4 AM trying to fix that. i ended up saying forget this and going to sleep.
When i woke up in the morning, i looked at the phone and i had my data and my cell service back so i was confused so i started texting my friends and when i tried to go tot he home screen, nothing happens. but what i learned earlier is that when i reboot the phone, my data and cell service goes away for a couple of hours. So here i am now with my droid bionic, and cant do anything but text and call. i can only call when i get a text from someone, open up the text, and click on the phone number and click call when it brings me to the contact page for the number. I am also not able to access the home screen, the settings folder, or anything besides the notification bar. i really need my phone to use email, games, software (learning how to write java code), and for school in some instances. Any help would be greatly appreciated.
Thank you for your time,

Seems to me...you lost data along the way.
A possible reason rsdlite is not recognizing your phone might be because you dont have the proper moto drivers installed.
Try this rsdlite and install the correct drivers for your pc...http://dl.dropbox.com/u/63864500/rsd_drivers.zip
Make sure your battery does not die!
Boot into AP fasboot (power and down volume)
Use the cable that came with your phone.
See if rsdlite recognizes the phone.
If it does, you can flash the full 902 xml file (make sure your pc has 4g of RAM tho)
Do you have the full 902 xml file...if not, let me know.

Drivers
Dear Sir/Madam,
I have the correct drivers installed. When i connect the phone regulry once it is all booted up, i am able to access the sd card and the internal storage via windows explorer.The problem is that the phone refuses to connect to the computer in fastboot mode. i do not want to risk rebooting unless it is guaranteed to work 100% because I can still text and call on it for some reason. Every time the phone is restarted, the radios stop working for a while and i need to be able to text my parents where and when to pick me up from school.
Thank you for your time,
NH85

i notice that you didn't once mention a wipe data or otherwise cleaning of previous ROM before flashing another (correct me if im wrong). also DO NOT have bootstrap and safestrap installed at the same time, this could be what caused all your problems. in order to switch between the two (which i've had to do for webtop issue), you have to return to STOCK +root, uninstall the currently used strapper, reboot, then install the other. things start getting even hairier if you forget that safestrap has both a safe/non-safe system. you need to be doing the switch on the non-safe system if necessary.
the purpose of safe-strap isn't that it can boot to recovery, it's that it *creates a an isolated ROM installation while preserving your "safe" system in case things like everything your experiencing occur. from what i can tell, you did not change to safe system before flashing new ROMs, again correct me if im wrong. at any rate, a bit of advice for the future is follow directions to the dot, but before even attempting the install read through AT LEAST 3 or 4 pages of user feedback to see what the common issues or install goofs are!
that being said...
having your computer recognize the phone as storage device does not necessarily mean you have the right drivers installed, however it does mean that you probably have the right cable (this is important, bionic is finicky without the proper moto cable). you will know if you have the right drivers if you see in device manager Motorola ADB. when you plug your USB cable in, there should be an option for "PC Mode" which will force the computer to search for the drivers you claim to have installed correctly. if not found, here is your chance to install them properly and test RSD to make sure device is detected.

Obviously you don't.
Mass storage and ADB are not the same drivers.
If you are in fastboot mode and your device doesn't connect, it's most likely your missing or don't have the fastboot drivers installed on your computer properly.
Once you get the ADB driver from motorola you can use fastboot start flashing.
The information you need is here
http://forum.xda-developers.com/showthread.php?p=22758211 .

I had trouble using RSD to flash the .902 FXZ.
What I had to do is extract the .img files from the ZIP, and use fastboot through CMD to get everything up and running.
Just open up the XML file inside the zip, it will show you the commands you need to type to flash each section and when to reboot the bootloader

[Q] Repair Galaxy Note N7000 SystemUI / TouchWiz home stopped working errors?

Hello everyone,
I've been literally 12 hours searching for possible answers on how to repair my Galaxy Note N7000 which from what I've concluded, has a problem that can be easily repaired but I've found nothing but limitations when I have a go at it. It doesn't seem to be bricked as I can still access recovery mode, download mode and it effectively boots, it's only giving me errors.
Here's what happened:
1) I tried rooting it using UnlockRoot PRO. Paid the PRO version, detected the device. Later I find it says the N7000 with 4.1.2 is not compatible so the rooting process was never completed, so I rooted it using Root_SuperSU.0.95.Only-signed and it worked just fine.
2) Everything worked fine, downloaded Andromizer to customize the phone.
3) Changed the DPI size to test it, then went to Developer Options and changed the Animation scales to 0.5 to make it all run faster.
4) Rebooted the device. Once I did, I got nothing but "SystemUI has stopped working" together with "TouchWiz home has stopped working errors".
I checked around the web and so far, what I've found (and tried) is this:
1) There seems to be a bug related to TouchWiz and the Animation Scale option (or perhaps the DPI size option in Andromizer). So I tried to do a wipe data / factory reset through recovery mode.
2) When trying the wipe data / factory reset through recovery mode, I rebooted the phone, only to find the SAME errors after I registered everything.
3) First option that came to mind was to wipe everything and immediatly reinstall the Official JellyBean 4.1.2 firmware (at this point I want to pretty much unroot the device as I didn't know it was going to give me so much trouble). When I tried that, I realized that SUDDENLY, Odin (nor Heimdall) are NOT detecting the phone in download mode. I'm guessing it's because USB Debugging is turned off but, I can't access the phone settings. It's my only logical conclusion, although it should be turned on given I could install PhilZ Custom Recovery later.
4) I search around the web and it says it's a driver problem. So I uninstall everything, run CCleaner, USBDeview to uninstall everything related to the Samsung Galaxy. Reboot. Install drivers again. Reboot. Plug booted phone and let Windows detect the device, installed successfully. Reboot in download mode. Let windows detect the device, installed successfully. Run Odin: DEVICE NOT DETECTED. (It does detect it while it's booted though, only it doesn't work for **** obviously).
I've literally tried everything. I've tried checking for a way to install the firmware via Recovery Mode instead of Download Mode. I've tried checking for a way to remotely access the device and mod the settings from there using ADB, and I get the same problem in ADB, doesn't detect the device.
Also tried to reset settings to normal via PhilZ Custom Recovery which I managed to install later.
Isn't there just a way to reset all settings to normal? Shouldn't a factory reset do this? How can I get SOMETHING to work and try to recover the phone? Any Aroma Recovery Script? Any way to mess with the system folder and modify settings manually via notepad or something since due to the SystemUI / TouchWiz home errors I can't access the phone settings?
I'm barely awake at this point. Can't believe I've stressed myself this much. Please help. This is beyond retarded.
Thank you,
Z

i had the same exact problem just few hours ago.....first of all you should boot into recovery mood by pressing vol up+ home button+lock button until samsung logo shows and then wipe all data/factory reset and wipe all cache partitions..........if that didnt fix it you should try rerooting it againg after re wiping

I read the post but it seems you have done a lot of things and nothing worked. So what is the situation right now? You can boot as normal but cannot get any icons or settings as sysUI and TW crashes?

Try installing GB ROM then wipe/cache first. If good, root GB ROM then do full wipe. Then test ROM for crashing.
If good then install JB rom and test. Let us know.

unable to enter phone setting ？ then just simply look for a secsetting.apk for ur version then replace it n set the permission rw-r--r--

Bwahahah, now I see why you guys enjoy calling newcomers "noobs".
It was a computer problem. I just reinstalled JB 4.1.2 from my netbook and it worked.
Weird as hell though, given that I updated my GT-N7000 to JB 4.1.2 through Odin in this computer and it never gave me any problems.
I AM going to learn some ADB / Android SDK though. I'd rather learn everything before something like this happens to me again.
I appreciate everyone's concern, and thank you all for it.

nice to hear that you had this one fixed

Glad to hear its working now.

[Q] USB/Blackrose Bad Combo Help

Hiya!
Been on the forums for years modding my Nexus One and would like to thank everyone for their humongous contribution! 3 years of constant upgrading and improving of what turned out to be the best phone ever!
Now, I've come to an end where my self-confidence took over caution and preparation and i think i've made a boo-boo.
Long story short, i have a unlocked Nexus One that has been running a CM10 ROM with Blackrose for a good 6 months. Most of the functions were working fine, except for a few glitches, but last night i decided to go back to the roots, and install a stock Gingerbread ROM. I found a unrooted GB ROM, and went straight on to renaming it to PASSIMG, throwing it on card and rebooting. Now that's where the funny things started:
First, all goes well, click Volume Up, get it started, and than a screen with all OKs except for [7] BOOTLOADER - Fail-PU and a message saying 'Only Blackrose can be flashed'
Next, I get 7 OKs, except for BOOTLOADER, and the following: Partition update fail! Update fail! Do you want to reboot? Y/N
Figuring i forgot to uninstall Blackrose and need to do so, i let it restart, it comes up with a clean un-rooted GB ROM, and here's where my troubles start.
1. USB Connection: Plug it in, laptop doesn't recognize it at all. Classifies it as 'Unknown Device' and that's it. Tried fresh drivers, Universal Naked Drivers, SDK drivers, ASUS tablet drivers, nothing. Tried 3 cables, the HTC one, a Blackberry one and a Samsung one. Nothing. Uninstalled all USB hubs/devices, restarted the laptop multiple times. Debugging ON/OFF, no difference. I'm at a loss here, no clue what else to try!
2. Fine, i thought, let's flash a rooted rom! PASSIMG on the card, phone finds it, gets to the line 'Parsing... Passimg.zip' and goes back to the neutral screen. Tried it multiple times, different ROMs, nothing.
3. At this point, figured maybe an earlier ROM will cause an OTA update and fix things up. FROYO PASSIMG on the card, flashed 'succesfully', just like in #1, reboot to clean un-rooted FROYO. Checked USB connection, same again. OTA Update - constantly failed.
Been reading through Wikis and Q&A's here all day today, everything seems to be so easy to fix as long as you get a live ADB connection, and i know i could fix it, but i just can't get the laptop to recognize the bloody phone! Do not have access to another computer just now, so can't check whether it's just my Vaio.
So now, the questions:
1. Any other ideas on the USB issue? The phone does not display the usual 'choose your option/mass storage...' when connected, and nowhere in the menu is there an option for that.
2. When booting into recovery, i get the green droid with the white triangle and the !, and then get into the 3e recovery that has an 'update.zip' option. can i install a custom recovery without the phone being rooted? just of the sdcard? is there an update.zip that can re-stock my HBOOT?
any other ideas will be greatly appreciated, as of right now i am stuck with a FROYO handset that is perfectly capable of running JB, and it's really frustrating!
thanks in advance for all your help, cheers!

Rooting Samsung Galaxy Tablet E (8.0) SM-T377V Please Help

So I've had success rooting the SM-T377V thanks to electronhacker post on the forums.
I thought I would give my experience because anyone else doing this will most likely run into the same problems I did. I still have a few problems I am running into. I hope someone can help me out.
electronhacker had said to downgrade to stock firmware LMY47X.T377VVRU1AOL7 (5.1.1) Lollipop, from firmware MMB29K.T377VVRS1BPL1 (6.0.1) Marshmallow using Odin.
I ran into problems finding LMY47X.T377VVRU1AOL7 but I eventually did find it on samsung-firmware.org Thank you moonsh0t!
It did actually work and passed with Odin, however it got stuck in a bootloop. I thought there was nothing that could be done but after looking into the bootloop matter more I figured out how to get out of it and start it up.
1.) Wait for the device to turn off while it's bootlooping.
2.) Then hold down the power button and the volume up buttons to enter recovery mode.
3.) Restore factory defaults. "I think this actually gave me an error but clearing the cache got it to work."
4.) Clear the cache.
5.) Reboot the device.
There you have it now you're out of your bootloop, the device will start up now.
Now that we have downgraded electronhacker had said to run a program called Kingoroot using the Windows application.
I ran Kingoroot and it got stuck at 44% and my screen went black and would not come on or turn off. I am pretty sure you call this a soft brick, but maybe it's called hard brick as there was nothing that could be done.
So this is what I did to Unbrick the tablet:
1.) Hold the power button and the volume down button for 15 to 30 seconds.
2.) The screen should come back on.
3.) Scroll through settings to reboot device normally.
I tried to use Kingoroot again. This time it got stuck at 51% and my screen on the tablet got stuck. Nothing was responding, not the power buttons, the volume buttons, home button, nor the screen. This is because Google Application had showed up on the tablet while I was in the middle of rooting. The Google Application said "Do you want to enable Google Security?".
Again;
1.) Hold the power button and the volume down button for 15 to 30 seconds.
2.) The screen should come back on.
3.) Scroll through settings to reboot device normally.
The device booted normally and I tried Kingoroot again. I wasn't going to give up. This time it worked, 100% Root Successful. I couldn't believe it the SM-T377V was rooted. I checked and verified with Root Checker.
Now this is where I need help!
#1.) The device only stays rooted until you restart it. Then you have to Re-Root it with Kingoroot every time you restart. I found out if you run SuperSu and go into setting you can stop this from happening. I'm not exactly sure what you do yet because I can NOT get into SuperSu. It tried to install the binaries but gets interrupted by Knox. It says disable Knox on SuperSu but this does NOT work. This tablet does NOT have a way to open Knox in order to disable it. So I need to figure out how to delete it that way I can run SuperSu and stop the never ending root process. So if someone could help me figure out how to do that I would very much appreciate it.
So far I've figured out that you can run an application called Titanium Backup to freeze the Knox files and then remove them followed by a Re-Boot to get rid of Knox. I looked further into my SuperSu problems and found out that you can manually download a SuperSu.apk file that should bypass Knox and actually disable it.
Here is my new problem, installed Titanium Backup from Google Play Store only to find out that I can't freeze the Knox settings unless I pay the $5.99 for Titanium Backup Pro. So I removed Titanium Backup and downloaded Titanium Backup Pro.apk which I found for free on the internet. I can NOT install it though, because I have a new error that says "APP not installed".
This happens with the SuperSu.apk that I found on the internet too. I've tried a lot of things but can't get them to install. Google Play Store gives me error (-504) I've tried clearing cache and data for Google Play Store and Google Play Services but no luck. I even tried downloading APK Installer but it doesn't even work. Please help I don't know what to do.
02-09-2017
<UPDATE>
I'm at a loss, so I decided to do a factory reset from settings and that did not get the applications to install. So then I tried to clear the cache but again no suck luck. Then I decided to enter recovery mode and factory reset, but then got stuck on "Your tablet is getting ready for you". or something along the lines of that and wouldn't get past that on start up. (This is because I disabled setup with another application, and is my fault.) Not being able to get past that I realized I had no choice but to Re-Flash the System Update LMY47X.T377VVRU1AOL7 (5.1.1) Lollipop with Odin and that was successful, thank God. Now I have to Re-Root and before installing the wrong applications, which are Google Play Store SuperSu and Titanium Backup. Reason being that once you install these once and uninstall them you can't install them again without getting error (-504) in Google Play Store or even outside the Google Play Store such as manually downloaded .APK files or you will get the error "APP not installed".
Here is my idea, and I haven't done it yet. Re-Flash, Re-Root, Install for the FIRST time the right SuperSu.apk and Titanium Backup Pro.apk in order to disable Knox and stop the never ending Re-Root every time the tablet it restarted.
02-10-2017
<UPDATE>
I have been running Kingoroot with my PC using USB. This gives me temporary Root access until Re-Boot. So I installed Kingoroot.apk and tried using to mobile application but this one works, but I get stuck in bootloop on restart of tablet. Then have to Re-Flash with Odin to get out of bootloop. I'm not having any luck.
#2.) Even with my temporary root I can not seem to install Xposed because of SDK 22 not supported. I was wondering if anyone knows a way to get it to work on SDK 22 so I can run IMEI Changer. Unless there is another way to change the IMEI without Xposed.
Thank you to electronhacker for your post I found on this forum which has made me a lot of progress, and thank you moonsh0t for your help redirecting me to find that firmware. :good:

I just got a SM-T377V this weekend and have been trying o root it as well. Wow seems like nobody has had any luck getting a reliable root on it. Please update me as you keep at it! Brent your attempts at this are amazing!! Keep at it!

I'm trying to get this thing rooted too, so please keep me updated if you find a
Way!! Thanks for your help!

Yep
Ok

Same issues here. I never have trouble rooting with the APK, but its super annoying having to reroot all the time. also the superuser app is absolute cancer so learning to replace that would be dope.

Alright, so your goal is to run an IMEI changer, but why?
Also my luck was to get it temped root and try and use chainfire's supersu to take over.
from there I tried unlocking the bootloader with samdunk. The issue though, is the CID was deleted from the tablet, so when I restarted, never ending bootloops.
I just Odin'd it back to the AOL firmware today, will look more into samdunk later.

If you use Odin to flash android 5.1.1 via package T377VVRU1AOL7, you can use the kingroot or kingoroot app (desktop or android) to temporarily root the device. From there, if you delete the kingroot or kingoroot app from the device you can use SuperSu to take the binary over. From there you can use any flashing apps you'd like.
The issue is at this point, the second the device turns off, when it comes back it will no longer have root. (note so far in my attempts I've found that Kingroot, will reboot rootless, whereas kingoroot will bootloop.)
Kingoroot will bootloop because it modifies the boot file in some way, which causes the bootlooping. The work around to this is just flashing over the previous android. However, if you flash with Odin, you lose root, but keep your files.
Going back to flashing, when you attempt to use Odin to flash other packages, they are denied, due to the locked bootloader, however, you can use Flashfire to flash these firmwares. I attempted to flash the T-377P firmware and bootloader. Obviously the locked bootloader stayed locked, the recovery partition got errored out, but the android system itself actually started. Just sans root.
It's worth noting I've also attempted using SamDunk, the S5 bootloader unlocking tool, and so far all I've noticed is it deletes the CID file and doesn't finish. So I'm of the impression that the temp root, isn't a full root either.

Samsung Tab s2 stuck booting into TWRP

Ive been lurking on this forum for a while but ive finally hit a wall I cant find an answer to
I successfully rooted my tablet using magisk and TWRP about 4 months ago, everything was going great. about 2 months ago my tablet booted up into TWRP and would not get out, no matter what I tried. eventually I fixed it by wiping everything and reflashing stock ROM from ODIN and going through the root process again, not a big deal. cut to 2 days ago, my tablet restarts and boots into TWRP again and wont boot into system, basically seemed like the same as before, until I plugged it into my computer
For some reason, my tablet no longer connects to ODIN or my laptop at all. Ive used the same cable and different device and same usb port and it worked just fine, ODIN picked up the connection and everything. Ive updated and unistalled and reinstalled drivers for all the USB ports and I dont think that is the issue. I even deleted and reinstalled ODIN but still nothing.
I thought maybe there was some setting on the tablet that might be preventing a connection to ODIN, so I wiped the rooted ROM off the tablet (im new to this, dont know if this was a bad idea) and tried again but got nothing. now with a soft bricked tablet I got a micro SD card, put a TWRP flashable version of the ROM onto it and plugged that into the tablet and flashed this new ROM onto the tablet, and that worked from what I can tell (system folder went from like 8mb to 17000 or something) but I still cannot get the tablet to boot into system.
I can access download mode (there appears to be two versions, one where it just says downloading and another where a bunch of text appears on the top left, some of it mentioning ODIN) and all the functions of TWRP, but ODIN does not connect and I cant get it to boot into the system.
TWRP version 3.1.0.1_ashyx
link to the post where I got the stock lite version of the ROM currently flashed to my tablet:
https://forum.xda-developers.com/tab-s2/development/rom-nougat-stock-lite-v1-t3746583
any help would be greatly appreciated, sorry for the wall of text.

Wish I had something useful to add. I'm having the same issue. TWRP 3.4.0.0 and LineageOS. I've had this issue forever. I flash a clean ROM, it works for a week or two, then I come back to it and all I get is recovery.
I can access Odin however.
Usually it takes wiping and installing a ROM to get the device working again, in fact it issue takes several rounds of that. But of course, in all of that I've lost my setup and some files.
Is there an actual solution to this?

On my T810 I'm having TWRP 3.3.1-0 with this ROM https://forum.xda-developers.com/tab-s2/development/rom-aospextended-rom-v6-7-t3979381
plus Magisk and Pico Gapps.
Of course it's only Pie and not Q, but working well.
3.4.4-0 not tested yet.
Once had an issue with black screen, but at that time I was using case with a screen cover.
Since that I've switched to TPU case only covering the back.
No more issues after that, perhaps it was a problem with FlipFlap like on other devices.
