So my Evo LTE is running 2.13.651.1, and is on what I understand to be the newest HBOOT (1.19). Naturally, I have S-ON as a result. This is my first Android device, and I've had it about a week since switching from an iOS device. I have root and the Teamwin recovery, which I used to backup the phone. I understand this is called a nandroid backup?
I plan to flash Cyanogenmod 10, in fact I already tried once. It resulted in a bootloop, and I restored from the nandroid backup. I have since learned I need to flash the boot.img from CM10 using fastboot, Flash Image GUI, or any other alternative. Once I do this, if I want to go back to Sense 4.1 like I have currently, how would I do so? Once I flash the boot.img from CM10, I won't simply be able to restore to my nandroid from teamwin, will I? I assume that if I tried to restore from the nandroid, due to S-ON I would be unable to write to the boot partition from a recovery utility and I would be left in another bootloop. How can I get a boot.img corresponding to my stock Sense 4.1 rom in the event that I want to revert to stock?
In the folder containing my nandroid backup, I see a file called boot.emmc.win and a boot.emmc.win.md5. I understand what the MD5 is for, but is the boot.emmc.win what I will need to undo the effect of flashing CM10's boot.img? If so, how would I use it (I do not recognize that file extension, and Flash Image GUI does not seem to like it either)? If not, where would I get something that will work?
I've done several searches here and on other forums, but I can't seem to find what I need. If someone has already answered this question, could you simply point me in the direction of that thread?
Thanks in advance,
Kristoffer
I have yet to restore a back up but to avoid any issues I would use dumlock. Install it from twrp advanced menu and reboot, open it in cm and it will backup boot and overwrite it with a temporary recovery, you then reboot and go back to dumlock and restore the back up, then you are free to flash the nandroid backup and reboot
When you reboot, do not boot to recovery, the boot partition has been replaced with a temporary twrp and all you need to do is reboot normally

Once I flash CM and its boot, the boot for my Sense 4.1 will have been overwritten, no? I opened Dumlock in my Sense rom (as I have not yet flashed CM successfully), and it gives me a warning to make a backup of boot PRIOR to using the app, then just under that says the app will make a backup of the boot. If I go ahead and run Dumlock, I'm not entirely sure what is going to happen. It seems that it will move my recovery (TeamWin at the moment) onto the boot partition? If this is the case, why is this something that needs to be done? Does moving the recovery onto the boot partition allow the recovery to write to the boot without S-OFF, thereby allowing a simple restore of the nandroid to replace my rom AND boot at the same time, as if I were restoring with S-OFF? Sorry if I'm not making sense, but I don't really know what I'm talking about here, and thats the only thing that makes sense to me.
I see a button in Dumlock that says "restore original boot." If I install CM and the CM boot, will pushing this "restore original boot" button give me back the boot setup for the stock Sense rom? If it does, then I could just push that button, let it do its thing, and then restore my Sense nandroid with my recovery, right?
Thanks for your help, and quick response.
Install HTC dumlock
Open the app and back up boot
Once back up is successful, press execute
Once the phone restarts it will only boot to twrp, you then go to dumlock menu again and restore boot
Now flash a Rom or restore back up and reboot
Sorry to sound ignorant, but will this method will restore the stock boot regardless of what rom/boot combination I'm currently running? Or is this creating a backup of the currently installed boot, and saving it somewhere for future use? Specifically, do I want to follow this procedure before I upgrade to CM so I have a backup of the current boot, or is this something I want to do if/when I want to go back from CM to Sense that will magically put the boot back how it was from the factory?
Yes, its a workaround that gives access to boot partition and will let you flash normally, I would only use it for stuff like nandroids rather normally flashing because it writes to boot 3 times. It's a lot of unnecessary wear and tear
Awesome, thanks alot for your help. I'm excited to go and try my CM10 rom, now I know how to get back to stock if I don't like it.
Thanks again,
Kristoffer
Hmm. Now I don't know what I've screwed up. I flashed the boot.img from the CM10 zip using Flash Image GUI, then rebooted to recovery and wiped the System partition and cleared dalvik/cache. Then I flashed the CM10 zip using twrp, cleared dalvik/cache, and rebooted. Now, I'm stuck at the CM boot animation again, just like last time. This does not seem terribly complicated, and I don't know what I've done wrong.
I understand twrp cannot flash the boot due to S-ON, but I thought flashing the boot from inside my Sense rom using Flash Image GUI would fix the problem. I restored the Sense nandroid like before, rebooted, and then I got the Recovery boot logo (htc logo, with red text underneath). After maybe a minute, that went away, and I got a Sprint logo and then the normal boot screen with only an HTC logo. The phone then restarted, and this process repeated several times. So, apparently whatever I did to the boot sector with Flash Image GUI wreaked whatever was there before, and failed to replace it with something that would play nice with CM.
A factory reset won't fix the boot, will it? All it will do is overwrite my system partition and internal sd with the default files, and I still won't be able to boot. Any idea what I've screwed up, and how I can fix it?
EDIT:
I reflashed the CM10 zip, and it still gets stuck at the CM boot logo (spinning blue thing). What are the chances my CM10 download is corrupt? Is it worth trying to redownload it, reflash boot with fastboot, then move the new zip to the phone and flash that?
What version of twrp are you using, some people have had issues with the older 2.1.8
Ok, progress. I'm on twrp 2.2.1. I wiped everything again (wiped cache and dalvik, Factory Reset, and then wiped System) and reflashed CM10. It booted this time, so I assume the boot partition is fine. Apparently I'm the retard that can't understand a point-and-click system and follow simple directions
Once it boots, however, I instantly see an error "Unfortunately, the process com.android.phone has stopped." Once I click Ok, the error will either pop back up immediately, or wait for an indefinite period and them come back. Possibly this is the result of the CM10 release not being entirely stable as of yet, I don't know.
But thanks again, your help and your fantastic Don't Panic post together fixed the problem. I think I can figure out what is going on with this error popup and fix it. So long as I have voice service in the interim, which I do, all is well in the world.
It's normal, it pops up when you lose signal, its a bug but its technically a feature. If the phone loses signal, normally android is supposed to prompt you so you are aware. I think its for debugging purposes, normally this is disabled. Not sure if its really a bug in cm or they just haven't gotten around to disabling it, but its normal. It's not a real priority either since it doesn't adversly affect the phone
Hmm. This just gets better and better. So CM10 ran nicely for awhile, then last night I rebooted the phone and the internal SD card failed to mount. Both twrp and the actual OS cannot get it to mount properly. Is this something I broke, or does it sometimes occur at random? I read the following, but I don't quite know where to go with it.

You're card is beyond a simple reformat, the physical address linking the card and or entire card is corrupt. Don't panic, you have to start clean. Back up the info on you external or remove it, make sure you have a ROM available on your PC. Go into recovery and repartition your phone, this will wipe all memory. You then load up a working ROM (a bad back up may be responsible or just reintroduce the problem), after you have flashed the ROM (HBOOT 1.15+ must fastboot kernel, unless S-OFF) go ahead and boot into android and restore your apps.

Repartitioning seems simple enough; twrp> advanced >partition SD card>swipe (leaving all settings default).
After that, I can flash the new rom and boot using fastboot from my PC, right? I'm confident that my nandroid of the stock rom is clean, because I didn't develop this problem until after I had been using CM10 for awhile. Could I use fastboot to flash the boot, data, and system from the nandroid, and be good to go? If not, is the most current file avalible to download at http://stockroms.net/file/HTCEvo4GLTE/RUU? the appropriate file I would need to restore the phone to its stock unrooted state.?
Also, none of my nandroid files have a .img file extension. Is this normal? It has the normal .md5 files, but everything else has a .win extention. I've never heard of this one. My boot, for example, seems to be backed up as boot.emmc.win, with a boot.emmc.win.md5 corresponding to it. Cache, data, and system backups are named <option>.ext4.win. Does ext4 has something to do with the filesystem of the backed up partition? If this is the case, what is a .emmc? Can I flash these files with their strange (to me, at least) extensions using fastboot as if they were all .img files?
I can't imagine any of this is really as complicated as it seems. I've used a PC and a jailbroken iDevice extensively, and never managed to break something I couldn't fix. I guess Android just doesn't like me, or something.
Thanks again for all your help.
EDIT:
Apparently physically removing the external SD from the phone allowed me to mount the internal SD as a USB device. The phone still refused to allow me to read/write data to the memory, but somehow managed to allow my PC to see it. I formatted the internal SD to fat32 (one of the limited options) using Windows, and rebooted the phone to recovery. Now, it suddenly can detect its internal SD. I was able to wipe everything, and restore my Cyanogen backup and the SD card now works again. Weird...
Since I didn't have to repartition anything, was the "physical address linking the card and or entire card" corrupt, or did I have some other issue? Also, I'm still curious about my above question pertaining to file extensions and restoring a nandroid via fastboot.
Hello,
I have a Kobo 10HD and rooted and installed CWM v6.0.5.1. I made a backup before and then installed Titanium Backup update.zip. Installation of that zip caused a bootloop (back to CWM). No problem, I thought, I can just restore the backup I made. No dice. I tried to restore the backup and still bootlooping. I even tried to installed the stock ROM ZIP and it fails with the message: (from recovery.log):
nv_copy_blob_file: couldn't get the device path
script aborted (no error message)
script aborted (no error message)I:Legacy property environment disabled.
E:Error in /data/media/0/macallan-ota-932.zip
(Status 7)
Installation aborted.
I have read that some people have had success installing this zip using stock recovery, but I have no idea how to get stock recovery.
Also, I noticed using adb shell that CWM does actually put all the files back into system and other areas during the restore. Upon reboot, and subsequent bootloop, the system files are gone. It must have something to do with an automatic script that is running after restore.
SOLVED!

After a few more hours of fiddling, I was able to get the device back up. I wiped absolutely everything manually with CWM (format /X) instead of Wipe/Factory Reset. The factory reset was not clearing the SD card, but format/data and /data/media cleared it. I then applied the stock zip that is available via adb sideload. Installation failed with the same error, but I rebooted with the adb reboot command. The device booted back into Kobo stock requiring several updates. It actually got stuck repeating one update several times until I booted back into stock recovery and cleared data and did a factory reset. The update applied correctly and then another upgrade came (a total of three upgrades). I rooted again and we are back in business.
For some reason, I think the key step was manually wiping /data/media. I'm not exactly sure why this would cause a bootloop for CWM restore. Anyway, I hope this helps someone else who may run into a similar issue.
Hi zhzhou!
Just a quick question:
do you happen to remember if stock recovery for Kobo was CWM? I'm in process of restoring stock ROM +recovery and little bet surprised to see CWM after flashing stock recovery
Thanks a lot!

Stock was definitely not CWM. It was a long time ago and I no longer have the device, but I think CWM was still present after restoring stock. I think you'll need fastboot if you want to flash the stock recovery image back on. But why do that? TWRP is now available for the device.
Thanks for quick reply! I had CM on it but had some artifact issues so wanted to revert to full stock, even recovery

Hey all,
I've got a N7105 (Galaxy Note II LTE) running CM12.1 and TWRP which I was planning to change shortly as it's old and the USB port has issues (charges but doesn't pass data; luckily it has a microsd slot). As it happens, the other day I left it discharge fully and turning it back on left it stuck at Samsung logo (not boot animation, the splash screen before it) forever.
I am: not a noob, I've rooted and flashed plenty of devices before.
I tried: removing battery for a while, charging fully, removing microsd and sim, clearing Cache and Dalvik. Nothing works.
I can: get into ODIN mode (but it's useless as USB data is not working); get into TWRP recovery; explore the Data partition in TWRP
I cannot: mount the System partition in TWRP, not even manually. It just does not let me select it, and gives an error whenever it needs to access it (e.g. if I try to backup it is says Error: unable to mount System)
I want: if possible to solve the issue without formatting Data. I had a TB backup but kinda old, so I got a Nandroid of Data and Boot out from TWRP and I suppose I could then recover stuff extracting from Nandroid through TB, but I've never done it and would rather be able to get a fresh TB backup and move on from there.
A few questions I have: any idea on why I am not able to mount System in TWRP? Could it help to reflash Boot or System, and if so how do I go to do that considering what I have is the whole CM rom package? (I remember being able to fastboot flash single partitions on Nexus devices but that's because the stock rom comes packaged in separate images).
Any input would be greatly appreciated!

The note 2 has this issue that makes it unable to be recognized by PC, so this isn't your phone problem, the only way to solve it is replacing the usb socket in your phone, anyway i can recommend dirty flashing your rom first, just flash the rom in recovery and wipe cache and Dalvik cache only then reboot.
If that didn't work, I'm afraid you might have to...... clear data ?

Thanks for the input, I was thinking something along those lines but I wasn't totally sure, I always avoided dirty flashing as I heard of people having issues. Happily, it worked! Weirdest think I saw in a while, it gave me a bunch of errors with System partition (unable to mount, unmount, find), then it gave a "proceeding to patch system partition unconditionally", then it completed. The whole thing took less than 20secs so I do not think it even actually flashed the ROM. Now I am just getting some Play Services error, likely need to reinstall gapps, but phone boots just fine!
So, I can't restore my backup due to the error above. When I restore my backup, I get that error and a reboot loops me straight back into TWRP. You can read all that stuff below if you need the backstory.
(I had Lineage OS 18.1 installed and wanted to restore a backup from two weeks ago. So, I booted into TWRP, did a normal factory reset and restored the Backup of Lineage. However, it put out an error regarding something in root (structure needs cleaning). I tried rebooting into system, but it ended in fastboot mode. So I googled it and one thread said you can solve that by formatting system. "System" is backed up anyway, so I thought there was no harm, wiped it and restored the same backup once again. No error this time.
However, when I rebooted into system, the unlock pattern didn't work any more, even though I never changed it and always use the same one. I had to reboot into recovery, and now the TWRP unlock pattern didn't work either. Had to skip it and did another reset.
Now, every time I restore a backup (and those backups contain basically every partition available) it works, but when I reboot into system it just stops at the boot logo, then reboots into recovery. Basically a boot loop plus. Tried a fresh flash, same loop.
Also, all of my pictures and downloaded files are gone, because it's encrypted. I had to wipe data, which led to the whole encryption issue going away, however, I'm still stuck in that loop.
Does anyone know how to solve this cluster****? How do I get it to boot into system?
Edit: Managed to flash LIneage new after wiping data and system and it actually boots, hallelujah, but when I flash the back up I'm still at square one with the same fail and it fails to boot. )
