[Q] Rom - wipe issues

Verizon Toro cdma
I I think I know what is wrong, but can't figure out exactly how to get it fixed. I crushed my screen this weekend on my GN. So I found a decent one on Craigs. Guy had it rooted/unlocked/JB. I'm not sure what bootloader he had on it and I know for a face that it did not have the latest JB Radios.
I basically want to wipe this thing and get a stock JB back on it and then put my backed up JB rom that I have in clockwork. I can not get it to recover to this backup, but I can get it to restore back to my ICS backup. I have been trying to use wugtoolkit and have successfully got CWM touch put on, but as far as roms, I'm stuck.
I can't even flash back to stock rom in Wug??
Every time I do a factory wipe, etc in CWR it will not boot.
I went to factory images on google and didn't see a 4.1.1?? I thought they came out with it?
Any help would be appreciated.

1) stop using a toolkit.
2) there are no factory images from google for JB for the vzw nexus up yet.
3) follow this guide to the return to stock and then get the OTA to JB: http://forum.xda-developers.com/showthread.php?t=1626895

I will look into it.
Thank you

I tried that way, but commandline fails to find fastboot. I can flash the stock image through toolkit (yeah I know you said not to, but it is the only thing that works) yet it will never boot afterwards. Also the radios fail to install.
I just understand why my backup will not install. I keep getting error while restoreing /system

did you follow the steps exactly?
doesnt sound like you did.

Yep, opened up my command line, cd to the directory where the files were unzipped with 7-zip. Typed in fastboot and it says it doesn't understand that command. Using Win7.
I don't understand the toolkit, and I understand the other way you pointed to helps you learn. Still doesn't explain why it is stuck at boot (google) and why my restore/backup doesn't work.

you dont have the fastboot.exe downloaded in that same folder.
EDIT: fastboot allows you to delete the /system parition and reload it with the stock images.

Hmmm, didn't see that in the steps. Ok, so where do I get the fastboot .exe... NEVERMIND. I found it.
I also noticed in his instructions that after you unzip everything that you should have 6 files, yet I have? I downloaded the yakju.
Going through the steps, got fastboot in there now and up and running.

uh you should not be using yakju. you need to be using mysid (thats the verizon version)
you could seriously screw up your phone if you use the GSM one (yakju)

got it and thanks again for pointing to that way. I see where my mistake was. I didn't download the toolkit with the other files.
Hmm, for some reason the radios did not work. Moving my .zip ones over now and will flash them. Hopefully will be back up and running full after a hour.

You might want to slow down a bit and do some reading first. 30 minutes of reading a few sticky'd posts can save you a lot of trouble. Read, understand, then flash (not the other way around). A good starting point is efrant's 101 & FAQ post.

Whoops. Flashing the correct one now.

You are correct on the slowing down part. I'm now back to where I need to be as far as starting out. I just missed that part on which file. I was thinking I could go straight to Jb, But i understand how to get there from here. That is the first time I have used fastboot and it was pretty easy.

Phone does not work/Will not boot - I'm desperate.

I've spent about 3 days and worked closely with a few knowledgeable people outside of this forum. I'm desperate and a bit terrified to start this topic. I've read too many to know how frustrating it to answer the same questions over and over again.
In short:
a.) Was running CM9, flashed using CWM. (Did not have issues and have flashed in the past with other roms successfully)
b.) Went to flash another ROM (can't remember which one) and did not back up (big mistake, troll away)
c.) Cannot get phone to start, can flash roms all day long and only get to their boot/splash screens. It will sit there until my battery dies
d.) I've tried Galaxy Nexus Toolkit and Wugs
e.) I've installed TWRP and formatted drive
f.) I've read and followed 3 full days of different forums and still can't figure this out. I've tried so many things it would take forever to type.
I'm severely desperate.
Will someone help me start from scratch and walk me through a surefire process. At this point, I'm lost. Nothing seems to work.
Apologies in advance and I am willing to accept the bad vibe. I'm lost.
Phone is a Verizon Galaxy Nexus

Did you try fully wiping, formatting /system, flashing a ROM and wiping cache after that? Or flashing another kernel?

Wow finally something
Wow! I finally got something to load. I'm on 4.0.2. I need to get back to jelly bean.

Wow, I'm stuck in nearly the same rut as you are in right now.
Experienced flasher here too - I was using the Xylon v18 until now, and Paranoid Android 2.99 before this. Yesterday night my phone rebooted after some weird Contacts application opening issue. And kept rebooting. One backup restore said there was an I/O error in /data/data/com.android.contacts or something. The backup never booted.
I have TWRP 2.4.0.0.
I tried new ROMs, different ROM backups, a few kernels, formatting /data including internal memory, tried Adb sideloading (said Read Only file system), finally installed Xylon v18 through Usb-otg, but it refused to go beyond Google logo. Restored a backup through OTG, and the same continues.
Could someone tell me what could be going on here?
I swear I was about to put in a post similar to the OP.
Thanks for the headsup just_some_dude, I'll go try an ICS rom now.

Edit1 : So it looks like my phone wanted to remind me what it feels like to actually jump with joy!
Installed the deodexed version of stock rom, and after a failed first boot, "Android is upgrading".
Edit2: Scratch that, couldn't get through phone setup. Changed to CWM 6.0.2.3. Flashed radio and RIL, PA2.99 again, and for now it seems to be working.

I was able to IMM76K, but phone wants to push newer version. I can't upgrade newer version without it getting stuck on that splash screen for the rom. I'm putting IMM76K back on.
So, weird. So much of this is not making sense to me.

Rebooting continuing for me despite different kernel and cache/dalvik wipes.
I'm sorry, absolutely not trying to hijack this thread. Only writing symptoms incase anyone notices something they have gone through too.
Baah, this is going to properly spoil my weekend.

Why not try to go back to stock by flashing the stock images first? At least you'd know if the phone works...

Thank you for the input.
I did, but in the zip, deodexed form. For me, all things are now pointing to Wifi causing the reboots, even when the Stock 4.2.1 was used I couldn't go past phone setup.
On PA2.99, after switching wifi off as soon as it booted, the phone is now stable for 10 minutes for the first time in 8 hours of trial-and-error.
Shouldn't XXLH1 flashing have fixed such things?

FIXED! It was a corrupted /data partition, which showed the /data/media or /sdcard was already 11 gb full after a full wipe with TWRP.
A /data and /data/media format with CWM did the trick!

For reference, that's not going back to stock. Back to stock means flashing the Google factory image, which would have also formatted your data partition, so do that in future

Ah, I did not know flashing the image wiped data partition as well, thanks!
I stopped looking for the image when I couldn't find JOP40G on the site. Classic case of beggars trying to be choosers. :cyclops:

I just tried to flash mmuzzy and gapps using wugs and am sitting at the Jelly Bean 'X' splash screen. I set it up so wugs would wipe data cache and Dalvik. Don't know what it is, but I cannot get Jelly Bean on this phone.

Tried flashing the Stock factory image? Not through recovery, but through fastboot. That is what I did ultimately.
Actually, my problem was deeper. My /userdata partition had some errors. On going through some posts here on /data partition corruption issues, these links helped me a lot, and made the phone ultimately much smoother than it ever was!
Definitely try the e2fsck command through adb shell while in recovery with /data partition unmounted. Try this before you flash a stock ROM image.
Here you go. I think these should help you too:
1. http://forum.xda-developers.com/showthread.php?t=1541379&page=4
2. http://forum.xda-developers.com/showthread.php?t=2025675
3. http://linux.101hacks.com/unix/e2fsck/ - e2fsck command options if you need help.
If adb asks you to 'check forced' because it finds problems, just use
Code:
adb shell "e2fsck -f /dev/block/platform/omap/omap_hsmmc.0/by-name/userdata"
I'm guessing it was all a result of months of flashing huge amount of ROMs. :angel:

[Q] "System UI has stopped" forever after installing custom ROM.

I'm not very good at Android technical stuffs as I'm new to it but learned decent basic knowledge before doing any rooting and flashing stuffs.
To start off, I installed ARHD 22.1 back in December and then upgraded to ARHD 30.1 just yesterday, successfully. I'm S-On, using Taiwan HTC One M8x 2.5 ghz unlocked.
I then decided to add the eXtremeBeats audio mod which is compatible to Android L. I followed the instruction there ( DL File, put to phone, flash via recovery, wipe cache & dalvik, reboot ). At the reboot the problem starts, after optimizing the apps, and then it says "starting apps" there it got stuck, I waited it for an hour and a half and decided to force shut my phone. So after turning it on again, it's now stuck on the HTC logo only. I decided to re-install ARHD 30.1 at that same day, successfully installed but when the phone starts, it says "Unfortunately, HTC Dot View has stopped" then followed by "Unfortunately, System UI has stopped". So yeah, I don't have any on screen bottons on my phone, no slide down notification, but can access apps ( no going back though ). I tried to wipe cache & dalvik again, tried re-installing the ARHD 30.1 again for the 3rd time, no luck.
I searched my problem at Google but mine's different. Their "Unfortunately, System UI has stopped" is like soldemly happening in the middle of phone usage and returning back to normal after some seconds, mine gets that problem at the very start up and the UI doesn't return.
What did I do wrong? What must I do? Thanks in advance!
Edit: I noticed that my OS is missing where it's supposed to say something like 3.28.xxx.x. I wiped everything including system at the time I install ARHD 30.1 the second time (where the problem occurred). I think this might have caused the problem? How do I fix this?

Restore your nandroid and see what happens.

Yes, I'm currently trying to figure out on how to do this. I'm having problems.
I have a Nandroid backup file in my PC. But I don't know how to push it to /sdcard/TWRP/BACKUP/. I tried the pushing file tutorial via mini-sdk and some cmd commands from ARHD's website tutorial, it can push to /data but I can't get it to work on /sdcard ( I tried to >mount /sdcard == gives error ). The other way I know is to transfer the Nandroid backup file from PC to phone normally via the file copy pasting, my computer can recognize my phone having the ARHD 30.1 (w/ UI problem) installed and USB Debugging on, though I can't access the storage or transfer files.
How do I push my Nandroid backup file from PC to /sdcard/TWRP/BACKUP ... ? Any advice please? I think this will solve my issue.

Yes, the syntax for adb pushing a TWRP backup to internal storage can be challenging. If you have a removable SD available, that might be easier, change the save location in TWRP to that. Then make a "mock" backup, purely so that the TWRP folder is created on the SD card. Then either copy/paste your nandroid to the SD with your phone connected to your PC; or use a card reader connected to your PC.
Alternately, you can try to mount the internal storage in TWRP instead of in the OS. That might work better.

Amazing! I understand the first method, but the alternative... can you explain a bit further? As I tap the Mount button at the main page of TWRP, it says "Select Partitions to Mount:", having System, Cache, Data, Micro SDCard, USB-OTG as options. And then nothing else to do, I see no any other button. Clearly I didn't understood the practice, and I google "How to mount internal storage to TWRP" but somehow didn't get any good result. Could you please tell me how it is done or link me to a guide?
Edit: The first method is fine, though I'd like to know how the second one is done. I apologize if you find me cumbersome but I'd like to learn, might come in handy at some peculiar point. I'm curious as what you said that that might work better but I can't perform the latter, it got me really cheesy
EDIT 2: I managed to do the BACKUP. But now it got stuck to BOOT LOOP. I tried to wipe data, cache, and dalvik... but still it BOOT LOOP. What now?

I'm having a similar problem, did you manage to fix it? How? Thanks.

NOT flashing the correct firmware / Kernel is a most frequent cause of SystemUI crashes. Flash the correct firmware/Kernel to correct this.

wth is wrong with my backup?
alright is there a specific solution to this? me and my mother both have the same phone so i took the lollipop backup from her, renamed it like mines and restored it. once i finish the restore and boot up im greeted with ''unfortunately system ui has stopped''. what gets me crazy and confused is that it works perfectly sometimes when i erase the system and everything then when i restore the same lollipop backup and here we go again, system ui has freakin' stopped! this doesnt happen to any other kitkat backup only lollipop.
i have twrp recovery 2.8.02
my hboot is 2.49
i am currently having s on.
i am sick of htc and their stupid s off and on thing like why should we pay 25 dollars i mean android hacking should be open source right? convert 25 $ to riyals and i cold live for a week, happily!!!

Hboot should be 3.19 in Lollipop. 2.49 is Android4.4.2 KitKat
Also, update your recovery. 2.8.7.0 works wonderfully.
Bottom line is you need to update your firmware before you try to restore a Lollipop backup.

Why bash on HTC and sunshine s-off ? You unlocked it, flashed twrp.....that's something HTC didn't nor the guys from sunshine. And you don't need s-off, it's not mandatory but it can make it easier.
I would kindly suggest to drop the ignorant attitude towards the wrong people and focus on the problem you have to solve.

That is not a valid hboot number for the M8 (which this forum section is specific to). I think you have a One Max.
But as mentioned, you can't just migrate a nandroid from one phone to another. The firmware needs to match also. Running a LP nandroid with KK firmware is going to result in issues.

Agreed. S-off isn't the problem, and not needed to remedy the previous user's issue. Main problem is lack of research before messing with the phone.

found an awesome solution. i used to have a nandroid of android 4.4.3, so i restored it, didn't do any kind of wipe and then restored my moms nandroid backup of android L. its working great! i have the htc one m7 dual sim m7_cdug 802w

[Q] Help needed with failed Rooting and Custom ROM installation.

Hi all,
Happy new owner of European model HTC One M9. Now stuck with white HTC boot screen and problems to turn it off and random strange things... I'm lost and need help desperately...
Followed all guides in unlocking through htc-dev, installing TWRP 2.8.6.4 (beta).
Made a copy of Stock ROM through nandroid backup.
Flashed SuperSU (UPDATE-SuperSU-v2.46).
Advanced wipe (did I by any means delete internal system?)
When flashing Android_Revolution_HD-One_M9_4.1_eda061 everything went haywire. Got message at end stating that not all processes were finished. Something with regard to E:mount -0 bind '/data/media/'sdcard' process errored with error=255. Now lots of issues...
1) I couldn't get passed the white boot HTC One screen. Had to keep my finger on the power off for ages.
2) Bootloader shows software status: modifed. unlocked. s-on. I assume this is correct?
3) Going into recovery I get a strange HTC message: This build is for development purposes only (+ disclaimer not to distribute outside HTC bla bla bla). Is this normal?
4) when I try to restore my Stock ROM through fastboot I get to the setup of the device, but then FC of different programs. Back, home and settings button are non-responsive. Even entered a strange HTC error check. Upon rebooting, clearing cache and Dalvik, I am stuck at white boot screen. Now I can't even get into android OS setup anymore.
I have tried nr 4 above several times without success. I do get a strange "Invalid sparse file format at header magi
erasing 'system'..." is this normal? I get OK at end - but then still back to white boot screen.
Is my system totally buggered? What have I done wrong? I've flashed HTCs and Samsungs several years as an amateur but I feel like a total noob... Help? Anyone?

the disclaimer is normal, and all that other stuff. before the fastboot restore did you flash stock recovery, I'm not sure but I think you have to, someone correct me if I'm wrong. pn advanced wipe you wipe cache-dalvic cache-system and data. nothing else before flashing a rom, if it has aroma installer select full wipe.

Hi,
Many thanks for your input. I tried to do a fastboot restore stock recovery (OTA 401.15) and afterwards a fastboot of my Stock ROM nandroid backup. It all seemed to work well (took longer than before - so I guess things got written to system) but I get foreclosures on several programs - most importantly Sense UI (even EasyAccessService and others less important as well). The SenseUI means I dont have any working buttons for apps, back and home. I wanted to see if I could delete the cache for SenseUI - but as soon as I try to go to apps, I get FC on App Helper. Same if I want to install anything.
- so I'm lost again... Any ideas?

I actually made two backups and I tried the second one. I realized I didn't wipe cache and dalvik after installing stock recovery. I've flashed so many times tonight i'm going mad. Went in to stock recovery and wiped it, and upon reset and a lot of sweating it all works back to square 1.
Maybe I'll stick to stock... :silly:
Many thanks for the headsup on stock recovery. That's probably the only thing I hadn't tried and I wouldn't have thought of. :good::good::good:

LG G3: Soft Bricked With Lost IMEI After Trying To Flash ROM

Soft bricked G3 with a lost IMEI number
Hey guys I have 2 major problems for my phone.
1) I was trying to flash Marshmallow 30B stock ROM yesterday, so I was told to install a few files. New system file, new modem file, new boot file and SuperSu BETA v2.65. I tried and tried many times yesterday, but unfortunately it didn't work. So I was like "okay fine, let's just use some custom ROM from XDA."
I chose the XenonHD 6.0 Experimental ROM and copied into my internal storage along with my gapps they recommended. I booted up into recovery mode, backed up the installed ROM and factory reset it. I went to flash my ROM first then my gapps. But then halfway flashing the log display showed this:
HTML:
unmount /system failed: No such volume found
updating partition details...
Then it ended saying it was successful and it continued on flashing the gapps and so on. Surprisingly no "unmount /data failed or anything, just the system that is acting up. After finishing flashing all the file, I went to reboot my device. At first it showed the LG logo as usual, then the screen became black. I went online and search all about this unmount system problem, and all they say is that I have to wait for about 10 minutes then the Android logo will come on. So I waited for 15 minutes? (I have an iPad mini beside me counting down the minutes). I came back the whole phone is still black screen, the whole screen is turned off, not idle blank screen. I started to freak out and I took out the battery and put it back again and went into recovery mode.
2) Another problem is this IMEI number loss, I don't know how I got lost this information. I'm not sure if my EFS file is corrupted or not. I realized it because I was receiving no cell signal while I was in the city central. Unfortunately I don't have a backup of the EFS file ( I don't even know if I have it ).
Please help me solve these problems. It's happened for a few days now.

After finishing flashing all the file, I went to reboot my device. At first it showed the LG logo as usual, then the screen became black. I went online and search all about this unmount system problem, and all they say is that I have to wait for about 10 minutes then the Android logo will come on. So I waited for 15 minutes? (I have an iPad mini beside me counting down the minutes). I came back the whole phone is still black screen, the whole screen is turned off, not idle blank screen. I started to freak out and I took out the battery and put it back again and went into recovery mode.
2) Another problem is this IMEI number loss, I don't know how I got lost this information. I'm not sure if my EFS file is corrupted or not. I realized it because I was receiving no cell signal while I was in the city central. Unfortunately I don't have a backup of the EFS file ( I don't even know if I have it ).
Please help me solve these problems. It's happened for a few days now.

i don't claim to be an expert in this field, but there are two things that come to mind that you could look into, maybe ask more experienced ppl on those threads.
it sounds like some sort of partition problem, or corrupt data, maybe you flashed a bad file or a file for another rom.
you could try manually formatting drives in command terminal without mounting them
also unbricking might work too but if your hopes and dreams are in this phone then talk to someone who knows more than me because i wouldn't bet my bankroll on these just suggestions for you to look into. I feel like the guys that write those guides probably can answer your question better and with more confidence.

I don't quite know how to do it though but I've been thinking about unbricking my phone and restoring to factory state and start all over again. Do you mind posting a link for the instruction on how to do all this? Thanks

This was the ROM I initially wanted to flash. I think something went at flashing the Modem causing my phone to have this unmount /system problem.
