[Q] Recovery and outdated device questions - Verizon HTC One (M7)

Hello,
I got my Htc One on Day 1 that Verizon released it and rooted it using rumrunner, for both S-off and root access with no problems. I have since to update my phone. I would like to update my phone to the latest radios and firmware, and start flashing custom roms.
My problem is I cannot make a backup from TWRP, my company required me to encrypt my phone to get work email but I have since had them remove the encryption but it seems that TWRP is still requesting a password to decrypt my data. I use the same password that I was using to encrypt my device but it says that it is wrong. I was thinking of factory resetting my phone but since there is no SD card will all the data that I have on my internal storage, i.e. the different backs ups I made from various apps still be on the internal storage or will they be deleted too.
Also once the encryption problem is resolved what is the best way to update my phone
Thanks

Everything you need is in this thread -
http://forum.xda-developers.com/showthread.php?t=2485319
Just download the newest rom, download the newest firmware package. Put the rom on your SD card, put the firmware in your adb / fastboot firectory etc.....instructions should all be on that page.
Flash the firmware first, get the newest version of TWRP from the original development section here, flash it next, then flash the new sense 6 / 4.4.2 rom from recovery. Profit. You are s-off, so should be easy. I don't think your encryption glitch will even effect the process. And if you mess something up, since you are s-off you can just RUU back to stock. Hope this helps.

[Q] How to Root/use Recovery on a fully encrypted International Note 2 LTE?

Hi all,
I recently got a HK N7105 and because it lacked the possibility to use a french keyboard I upgraded to a stock unbranded ROM from Sweden (XXDLL1) and succesfully rooted with the relevant CF_autoroot through Odin. Also installed TWRP 2.3.3.1.
Then, I connected the Note 2 to my corporate exchange server which enforced a full encryption policy (device and external SD card) so I had to type in a password at each boot time (with a "nice" swedish prompt that took ma while to decypher), plus a password to unlock the screen. All was well as the root survived the process.
Next I upgraded to a later stock ROM from France (XXDLL4 from SFR) to try and get rid of the swedish prompt. That worked fine (and root was loast in the process, as expected) but I hated the branded stuff so much I reverted to XXDLL1 until a proper unbranded "english" or "french" ROM is available.
At this point I decided to root again. I was running XXDLL1 like the first time and used the same autoroot tar from Chainfire. Except my Note 2 was still encrypted and after that it would not accept my boot password (a four digit PIN) anymore so I was guted and had to factory reset and root then reinstall everything before reconnecting to the exchange server.
Question 1: Does anyone know of a safe, proven way to root a fully encrypted Samsung device so I can go another upgrade without having to wipe the device first?
Why reinstall everything? Why not backup everything first so you can restore after the wipe? Well, it so happens that no recovery (at least neither CWM or TWRP) can read any encrypted media on the Note 2 at the moment. And no Recovery can actually fully backup the device as well.
Question 2: Does anyone know of a proper way to handle this situation with minimum hassle?
So far, the best I can think of is doing a Titanium backup and FTP the files to my NAS so I can retrieve them later. But (Question 3) will this be enough to restore my phone to the expected state after a stock firmware upgrade?
Thanks in advance,
François

I think using Exynos Abuse apk will do the work

Thanks for the heads up, I'll look into it. But to be clear, that answers question 1, correct?

Yes that's a way to root the device.
Regarding encryption, very few people on xda seem to use it. So for that reason you'll have trouble finding out what works... I do use it though through choice so I can help you a bit.
When you encrypt the device, just consider /data to be off limits to anything not booted fully. That's why it asks you for your key in swedish - it can't see what language is in use until you unlock /data.
You will have issues using recovery with the device, since they can't read /data. You can use an external sd to perhaps load data to the device though.
I believe that TWRP might soon support the Samsung encryption on the device, meaning you could use it as recovery. Once you have a recovery that supports Samsung encryption, you should be able to consider it a fairly normal device.
Just be more cautious to backup your data as it is hard to recover if something goes wrong...
If your using stock rom 4.1.2, exynos abuse method of root will not work. It's been patched

Fine, I understand. As long as I have a way to recover my data if I need to wipe I'm okay... I just have to hope Titanium backup gives me that until TWRP can manage encruption on the Note 2.
I'm really waiting for a stock rom that boots in English or French now.

I am on Stock 4.1.2 and Exynos Abuse did work on my device, it's successfully rooted using the Exynos AbuseAPK on 4.1.2 :good:
OK, now I have been experimenting a bit with backups and upgrade and have trouble restoring my device fully. Let me explain...
I got hold of a TWRP build that seems to handle Samsung encryption fine through one of the TWRP devs (thanks!), so I decided to go back and try to update my device.
Current ROM: N7105XXDLL1_N7105TLADLL1_N7105XXDLK7_HOME.tar (obtained from Samsung Updates)
New ROM: N7105XXDLL7_N7105OLBDLL2_N7105DXDLL1_HOME.tar (obtained from Samsung Updates)
First I performed a complete Titanium Backup on the device and pulled the files to my laptop using ADB.
Then I restarted into TWRP 2.4.0.0 (got a prompt for my password), performed a full backup and pulled the files to the laptop using ADB.
(for some reason, I could not install the new ROM from TWRP (unable to open ZIP), but the ZIP looked OK, as well as after a second download which TWRP since did not like, so I had to use Odin instead).
Next, I flashed DLL7 with Odin. It worked, asked for the password at boot, but the device was unrooted at this point (I expected that).
Then, I flashed CF-Auto-Root-t0lte-t0ltexx-gtn7105.tar from Odin, but the boot up password would not be accepted anymore as I already knew.
Tried to flash DLL7 again from Odin, same thing
Flashed TWRP back on recovery partition, but on startup it would not ask for password anymore and the external sdcard looked empty to it.
I then copied my backup to a different, non encrypted sdcard and could restore from TWRP but the password would still not work after reboot.
I did a factory reset, restored backup, same result.
At this point I decided to factory reset, wipe Dalvik and format /data. The format did the trick and after TWRP restore of my original back up the device booted up, did not ask for password and all my data was there. Except the Exchange account I use for Corporate email wants me to restore encryption in order to work (I expected that too).
Back at DLL1, so I flashed DLL7 again with Odin (OK), rooted the phone, triangled away the flash counter and reflashed TWRP to recovery.
I was where I wanted to be except for one thing: I need to restore Corporate access. But when I let it encryp the phone it does nothing. I let it through the night and nothing). And if I reboot the phone no password is needed at boot time, yet the phone seems to behave as if it thought the device was still encrypted...
I reflashed my original, full, backup (i.e DLL1) succesfully but Exchange still wants to encrypt my device. Isn't restore supposed to restore the encrypted /data I backed up?
At this point I'm left with possibly tryinjg to go back to full factory settings, not use the backup at all, encrypt the device then restore my data from the Titanium backup I made.
Is there a better option?
[edited jan 18 - TWRP/TB behaviour]
My comments apply to encrypted devices only! I am not trying to talk down TWRP or TB here, as they provide splendid performance on non encrypted devices. I have come upon hard time trying to upgrade/restore an encrypted device using thoise tools, that's all
For those considering upgrading & re-rooting encrypted devices, don't!
I am finding the hard way that this is a one way street. At this point, my TWRP made full backup does not restore the device to the expected status. Each time I apply it, subsequent bootup takes several minutes and I end up going through the initial setup procedure. It seems the device for some reasoin goes through a complete reset procedure.
[edit]
Clarification: The TWRP build I use, 2.4.0.0 is an alpha build and I was not current when I restored my backup. I so happens that it was overwriting the encryption header on the partition, which messed things up bad, and had issues writing back the data partition, ending up in a factory reset status!
Using the latest drop as of today (jan 27) I was able to restore my original backup and am now back to my original state. All is well.
[/edit]
Titanium Backup is none better. It keeps telling me that my Android ID has changed, a host of system applications start to fail when I try to restore and generally speaking I have now spent between a good 20 hours trying to simply restore my data.
[edit]
this behaviour is probably linked to encryption. I know for a fact that TB works very well on non encrypted phones. The 20h figure is overall, not just with TB.
[/edit]
The end story is: root before you encrypt, and either don't upgrade or don't re-root if you do! If you do, be prepared for some rough times...
Unless someone has a cleat idea of how to do this properly without losing all your data, that is.

I have had no issues despite doing upgrades, with and without wipes.
Titanium is fine, just stop restoring system app data. Seriously, what data do you have in a system app that you want to restore.
Restore your user apps, their data, and the xml based call, sms, Wifi backups. It will work fine.
Device ID isn't a problem - it's just trying to help you.

Sorry if I came across dissing Titanium Backup and/or TWRP. This was not the intent... I am sure both tools work real nice in general cases (and I have had success restoring data on a Jetstream before).
My main issue here is _full device encryption_ enforced by my company's corporate IT to allow me on the corporate exchange server. Do you have full device encryption on?
On my device, even after a full wipe and flashing a fresh stock rom Titanium Backup just did not work as I hoped. When I had to confirm individual popups of apps closing unexpectedly while it was proceeding and got nothing back in the end, what was I supposed to think? It could be that I don't understand how TB works... I was neither able to restore missing apps after the flash (missing apps: 0) nor installed apps data (they would close unexpectedly when started after restoring the back up). So I say: until full operation of TB on encrypted devices is documented, I will stay away from it, even though I am a registered user (and I do not plan to seek reimbursment)!
Anyway, I got to a belated happy ending (previous post edited).

Yup I use device encryption Enabled manually, but it's the same encryption.
You should find that titanium shouldn't even be aware of it - the encryption is transparent!
I wonder... I'm sure lenny had that issue on a recent 4.1.2 "stock" ROM... And he doesn't use encryption...
I personally have had no issues with titanium on an encrypted device anyway
I notice you were using the newest rom - that's the one lenny had issues on.

Exactly like I thought, encryption should be transparent to Titanium Backup since it runs within the OS.
I have had problems restoring into 4.1.2 DLL1 (the build I came from) and DLL7 (the one I was trying to go to)
The point is moot anyway since the DLL7 I tried was actually branded (Singtel stuff all around the launcher) and did not include French, which is why restoring my TWRP backup was a tempting proposition.
Good to know TB runs fine with encryption as well. What ROM are you running?

About a backup : have you tried Online Nandroid (Playstore) (or similar, based on Onandroid) ? This makes a CWM or TWRP compatible backup while the device is running (everything should be unencrypted at this moment).
See http://forum.xda-developers.com/showthread.php?t=1620255
About rooting : you can try the same trick as above, by using ADB-shell and pushing the needed files to root to the device while it is running.
For my S3 there is a Toolkit that automates all this (http://forum.xda-developers.com/showthread.php?t=1703488), maybe there is something similar for your device ?
If not, you should still be able to do it using manual ADB-pushing.
I'm sorry I can't give you detailed instructions about the rooting as I'm not familiar with your device. Search here on XDA and you'll find more details.

Thanks for the suggestions, and no I had not tried Online Nandroid as I was not aware of it. Anyway, my main issue is now resolved since TWRP has include support for Samsung TouchWiz based encryption in 2.4 and that works well.
For those interested, the only remaining issues I have with TWRP regarding encryption are that if you want to format /data from TWRP (say, to remove encryption) it will fail unless you _do not_ enter the password at boot, and the TWRP formated /data cannot be re-encrypted (you must use stock recovery to factory reset/wipe the device or else the encryption step will sit deat in the water doing nothing). I suppose the second one is a bug that will be fixed in a later version.
I will check Online Nandroid out anyway, being able to make a backup from a live system sounds good!

I have a similar issue. I had the device encrypted and decided to ROOT (using CF-AutoRoot). Unfortunately I cannot bypass the password screen now, although I know that I'm entering the right password. You are saying that if I flash TWRP everything will be fine?

Two separate things:
Root messing up encrypted touchwiz devices and twrp not handling touchwiz encrypted partitions properly.
The 2nd one, as much as I can tell, is fixed since before 2.5 so if youwork with the latest (2.6) you should be fine.
The first one I haven't played with in a while, but my finding is that you don't want to root a device once it's been encrypted. I've tried several different methods including rooting as you flag as is possible with twrp and all end up the same:the password is not recognised anymore!
The only thing that works for me is rooting before encrypting or only flashing pre-rooted ROMs.

Yes - I had to factory reset the phone and format the SD Card. Never root AFTER encryption :silly:

Edit Oct 17, 2014 - Encrypt your device/phone with custom ROM

Disclaimer: I am not responsible for any damage or liability arising out of these steps. I did not invent anything, I just tried something. Only move forward at your risk
If you don't agree ... stop reading and move on...
Background: Our phone has access to so much personal information that its scary if it fell into wrong hands. The only way to fix this is to encrypt phone. I did lot of research and here is a working solution that works for me - try at your risk.
Download Links:
a) Tested with ROM Stock 4.4.4 NH7 Galaxy S4 M919/Jfltetmo by @ShinySide
b) Tested with ROM |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
c) stock recovery AT&T S4 works with M919
d) Philz/CWM custom recovery
Encrypting with custom rom
1) Assume you are on custom recovery. - Backup everything first. Create a nandroid backup
2) Do a full wipe and install one of the two roms linked above (I have tested with few other roms ... none worked). Start the phone and set it up the way you want. Install all apps etc.
3) ODIN Stock recovery. See #c under download above. Its AT&T stock recovery but works for me. You need to know how to ODIN - find out. Doing this wrong will permanently damage your phone
4) Start your phone and turn on encryption. You will need to set lock type = password and will need to connect to charger and have 80% charge.
- Phone will do blank and stay blank for 20-30 minutes. Do not do anything. Encryption is happening behind the scenes.
- You might have to do this twice or thrice if it did not encrypt first time. For me the phone went blank first time and after 25 minutes it restarted but device was not encrypted. I redid the same steps and worked second time.
- If you interrupt the encryption process (battery pull or power up) you will see error message (encryption failed, reset device)
5) If all goes well you now have a password protected encrypted phone with custom rom!!! Check in Settings -> Security
6) You may install custom recovery ... but I don't see the point because you will need stock recovery to decrypt
To install another ROM
1) Reboot into stock recovery, then wipe data and cache (this removes encryption).
2) install your recovery of choice and install ROM using recovery. Philz/CWM

How to Flash a rom on an encrypted Android phone (specifically this one, the I9505 SGH-I337).
The Problem: Once encrypted, you can't decrypt it easily. When encrypting the phone android will tell you you can only decrypt it using a factory reset. Naturally you assume it's talking about the "Factory Data Reset" option found in Settings --> Backup and Reset. But noooo, Android is lying through its ****ing teeth. Then you'll assume you have to wipe everything from your custom recovery mod (CWM, TWRP, or one of those). Wrong again! You'll get beautiful "can't mount /data" messages and more bull****. I read about a workaround that required installing the new rom using ADB, but I had ingeniously disabled USB debugging prior to wiping everything, so I only got so far with that option (plus it's tediously long if you haven't installed all the necessary software already and don't feel like bricking your phone because you made a typo in the command line). So, apparently the only other way to really format that partition free of its encryption is to use a stock recovery. So:
Short Version for Godlike users who know automatically how to do all this **** without any help (mimicking how most help posts are finely detailed on this site): Flash stock recovery, wipe everything, flash your custom recovery and install your new rom.
Long version for us mortals who don't know everything and haven't already downloaded already every single bit of software on earth:
Backup all the stuff you want to save. This process will truly wipe EVERYTHING. You can do it manually, or you can use an app like Titanium Backup Pro to help you (find it on Google Play Store). Here's a nice guide which recommends what to restore and what not to restore: http://forum.xda-developers.com/showthread.php?t=1480343

In step 6 replace "recovery.tar.md5" with the stock recovery you downloaded.
Wipe everything from the Stock recovery console. This little ****er will **** up the encryption all those sissies couldn't touch. You're welcome. You boot into recovery mode from a turned off phone by pressing simultaneously the volume up key + the home key + the power key until you see blue text appearing in the top left corner of your screen.
Reinstall your custom recovery. In my case I had installed the rom BEFORE flashing in the stock recovery (apparently it works, you just can't boot because of the encryption), so I was able to boot into the new rom before I returned to my custom recovery. Weird. Anyways, I recommend CWM. You can pick it up from this link: http://goo.im/devs/philz_touch/CWM_Advanced_Edition/jflte
For some weird reason they call the I337 version the "jflte" version. It's bonkers. Click there, and download the latest version that ends with .tar.md5. This version is upgradable via Odin, which we already used. Use the same instructions used as when you upgraded the stock recovery rom.
Boot into your recovery mod and flash your rom like you usually do.
A word about TWRP: it cost me many hours of work and I don't recommend it. Its website is outdated, and recommends using GooManager (which is no longer mantained) and doesn't work anymore for this. GooManager suggests using a new, different app, which doesn't have the option of installing TWRP. Then I tried using their TWRP Manager app from play store and the image file wouldn't download. Then I tried manually selecting the image file in TWRP manager that I downloaded from their site for use via the ADB method, and it bricked my phone... twice (using two different methods the app sugested). I tried so much because in theory TWRP has the ability to decrypt android's 4.4 encryption, but after looking at their github site I noticed it was filled with people's reports (including people with the S4) on how it wouldn't work decrypting squat. So I gave up, and installed CWM in 30 seconds.

One of the things I needed was the ability to encrypt my phone (device only not external SD) for security purpose. Our phones today gives access to lot of information that I would rather not fall in wrong hands. I did lot of research and here is a working solution.
Credit goes to @Tronicus and his reply Flash a Rom on an Encrypted Android
The quote looks long however it is really very simple. To install another ROM
- Install and reboot into stock recovery, then wipe data and cache (this removes encryption).
- Then install your recovery of choice and install ROM using recovery. Philz/CWM
This has been tested working on |ROM|★KANGAKAT★|►KTU84P◄|4.4.4|Xposed|►8◄|6.26.14 by @iB4STiD
This did NOT work on a Touchwiz ROM by same developer
I have not tested any other ROM

I don't know if it matters too much or not, but the stock recovery you linked to is for the AT&T S4. A good rule of thumb is to never use Odin to flash anything not specifically for your particular device... In this case the M919.

Honestly im surprised its not talked about more since there is a big push for personal privacy when it comes to data. Encryption really is a pain in the ass to work with on android. Figuring out how to switch or update custom roms while encrypted will drive you insane. The easiest way is to just odin back to stock and start over, but that requires a computer anytime you need to flash anything.
I recently was trying out one of the 4.4.4 GPE roms and turned on encryption. It worked great until i started missing touchwiz and wanted to go back to HyperDrive TW. So the journey began...
First of all, i backed up everything to external storage since i knew everything on the internal storage would have to be wiped. I loaded the phone into recovery mode (using TWRP) and tried wiping, but all i got was a bunch of "Failed to mount" errors. Fine. Got the same error when trying to factory reset or wiping /system, /data, /cache, and anything else. Tried formatting to different file systems and then formatting back to the original but no luck. Fixing permissions didnt help. I just kept trying everything available multiple times.
Eventually it started wiping everything except the /data mount. Well... At least i could install new custom roms. Im not sure exactly what did it because i was just throwing everything at it. Anyways I got it to install, and booted into it. Nope.
Now it was saying I needed the password to decrypt the internal storage. It would detect wrong passwords fine, but as soon as i put the correct password in, it would allow me in, show the green android encryption picture, then blank screen. I thought it was just decrypting and setting up my rom but after a few hours my screen was still black and nothing was happening. Pulled battery and went back to TWRP.
I started wiping everything again and again and tried doing everything i could to wipe everything on the internal storage. Again, not sure what did it, but eventually got it all cleaned up and got a new rom installed and could boot into it.
The whole process probably took about 6-7 hours...
I dont even want to enable encryption on the new rom...

Yeah Encryption does not seem to work on TWZ roms. I tried on G Eye without luck.
I have updated op. Please check
Encryption will slow down your phone quite a bit. More battery usage + more CPU usage + slower phone = not worth it unless you've got some very private stuff you don't want being shared. Otherwise, 3rd party apps that lock a lot of files, can encrypt certain files, and hide others will do the trick perfectly well.'
Not trying to bash fully encrypting your phone, but I've tried it before and although I am very pro privacy, I had to eventually take it off due to all the extra hassle it created.
Don't know about slowing down. I am not seeing it. I feel differently about security.

[Q] Help with downgrade and/or re-unlock, possible flash new OS

Hi, total noob to Android hacking and rooting here...
I'm in the US and have the HTC Desire 816 (710c) on Virgin Mobile. Really wishing I'd done better research about the Desire 816 and VM before buying this phone. It's a great phone except for the small HD. I didn't realize just how many headaches that small HD--and Virgin's tight-fisted grip regarding their unlock policy--would cause me!
Forgive the length of this, but I'm hoping more detail as to what I've done/tried will help find the right solution...
I was doing fine on KitKat and for some reason decided I wanted to upgrade to Lollipop--mistake number 1! I first installed the update over KitKat but had some issues. Nothing major, but I figured something was definitely wonky when I noticed the basic stock web browser was gone--not that I really use it, just wanted to test something with it. (I was having an issue in Habit Browser, didn't realize 'til later that it was because I had my download folder setting on external SD card. While that worked in KK, it didn't in LP.) So, I did a backup...or THOUGHT I did. HTC Backup app was supposed to have been backing up my phone every day to Drive...turns out, it wasn't, despite notifications that it was working. So, anyway... I went ahead and factory reset the phone and reinstalled Lollipop. UGH! An even bigger mistake. Over 6 GB of the HD gone, just from stock LP!
Then I thought maybe if I unlocked the phone, I could delete most of the junk, even still using the stock OS. I followed the directions on HTCDev and although the proper screen appeared on the phone and asked me if I wanted to unlock, and I replied yes, it didn't work at first. The phone rebooted and everything was the same. Reboot checker confirmed failure.
So, as I was ready to try to narrow down my list of previously installed apps to absolute essentials due to the reduced disk space, I thought to see if there was a a way to revert to KitKat. I followed the instructions here http://forum.xda-developers.com/desire-816/general/ruu-t2952058. I tried the RUU .exe first. It failed, telling me I needed to get the correct RUU and try again. However, HTC's website does NOT show any KK downloads for Virgin Mobile USA for this device. More on that in a moment...
I also tried the flashing via SD card method. It also failed. I thought, what the heck, I'll try steps 3 and 4 of the SD card method, flashing the stock recovery and lock the bootloader, even though I thought my device was locked. Well, I guess I didn't notice when I went into fastboot that the device indeed HAD at some point unlocked, after all.
After those steps, I now had the following show up:
*** Software Status: Modified ***
*** RELOCKED ***
SECURITY ALERT!
I tried flashing the ROM.zip from SD card method again. It failed spectacularly, saying something about about a large file (some of the text was beyond the edges of the screen, so I couldn't read all of it. There was also an instruction to press power to reboot. The phone went back into fast boot screen with red highlighted "!! Image Update FAIL !!" Mind you, this was with the SD card now removed. I did manage to get the phone to boot normally again, back to stock Lollipop.
Now I thought I would try flashing the WWE KK download from HTCDev. Well, I didn't get the large image fail message, but it did fail saying that it was not the right image.
I tried unlocking the phone again, via the instructions at HTCDev. Didn't work. Thought I would try the ROM.zip file from the thread here at XDA one more time. Same fail message as before, same behavior of phone getting stuck on flashboot screen with red error message on initial attempt to reboot the device. I do notice now that although phone status is still modified and relocked, the security alert message is gone.
Can anyone help? I just want KitKat back so I can reload all my previous apps! (or possibly a good KK equivalent non-stock ROM, once I get the phone unlocked again? I have no idea which one though, being a noob :/ )
Thanks!

That ruu file should work it's the vm usa last kitkat version. You need to follow the directions unroot and relock phone. But depending on what you did to the phone that was non standard you might also need to wipe or format internal data before running the ruu.
I think you can:
1) unroot then boot into recovery(twrp)
2) wipe phone/format data.
3) Boot directly from twrp to bootloader so you can get to fastboot usb.
4) Flash stock recovery from your PC.
5) Relock bootloader then run the ruu.exe.
All the other stuff you did afterwards should not be necessary.
pcjunky: The phone is currently relocked. I'm not 100% sure about unrooted, but I think it is. Like I said, when it was unlocked before I didn't even realize it, and I didn't really do anything unusual with it. The phone still had stock Lollipop on it and I just changed some stock settings and preferences.
Also, as I said, I am a total noob. I don't know what you mean about twrp and booting into that to wipe the drive and then from that. I'm sure there is info about that on this site somewhere, but it might be quicker if you (or someone) could explain it briefly, or point me in the right direction.
Updating to answer my own question in this reply. You're telling me to use a custom recovery but I never installed one. So.... currently searching to see how to do that.
I don't know if it's worth you time to learn how to go back to Kitkat. There should be howto's in the general forum for most everything you need. But I think the free memory difference between Kitkat and Lollipop is almost 1GB. 4.04GB free versus 3.14GB free. If you make sure all your apps that support being moved to SD card are moved and your storage settings for supported items uses the SD card you might be able to save enough space to get by until you decide to switch phones.
Twrp is a custom recovery and backup/restore tool you can do a search to learn about it, but you might not need it. The HTC backup is OS specific and it only saves apps and data not system files. So your HTC backup under Kitkat won't restore over Lollipop. If you had installed Twrp and and made a backup of Kitkat before you installed Lollipop you could restore your kitkat backup over Lollipop.
If you still want to try to get back to kitkat you can try to reset your phone(In theory relocking your phone should do that but it wont hurt) before you run the ruu file.

Well, it's interesting to note that my phone used ~ 4.8 GB when it was new with KK installed. After the Lollipop upgrade, it was using well over 6 GB with just the stock OS, HTC apps and Virgin apps on it. Obviously, that was unacceptable, and it's what got me started on this whole quest. :silly: However, after flashing a custom recover image, rather than the stock recovery I used previously, the stock installation is using 4.97 GB, so I think I should be good to go with that.

I always have used the SD card as much as was supported. Switching phones is not an option for me as I have a rather limited income and the Desire was an investment. Thus another reason I embarked on trying to make these changes.
Twrp is a custom recovery and backup/restore tool you can do a search to learn about it, but you might not need it. The HTC backup is OS specific and it only saves apps and data not system files. So your HTC backup under Kitkat won't restore over Lollipop.

Well, as I said above, the stock/OME installation now, before uninstalling whatever junk it will let me, is using only 4.97 GB, so I should be fine with that.
Thanks for your efforts to help me out with this. :good:
I'm glad you got it to a workable point. It's possible to go back to Kitkat, but I personally wouldn't do it because it gives you better battery life.
From time to time you should check apps under settings and swipe left to see the apps on sd card. Sometimes new app updates will support being moved to sd card or an updated version of an app will need to be moved over to the sd card.

Lineage/CyanogenMod requires password on boot

Hello all!
So I've been rooting and installing custom ROMs on my Android phones since getting started on my Galaxy S2 back in the day, and as it stands I've never encountered such an annoying roadblock as I've been forced to deal with over the past few days.
I just got a new HTC 10, and quickly went ahead and rooted my phone to get a custom ROM on there. The ROM seemed to boot fine, but the home button wasn't working and I had forgotten to download and install GApps. The other problem was, upon flashing the new LineageOS, TWRP would not recognize any files whatsoever on my device--including the backup I had made. So, I went ahead and flashed the latest RUU and returned to stock. After realizing the RUU is Nougat firmware, I got the latest TWRP and went ahead to try and reinstall Lineage again.
This time, however, the phone decided to stop on a screen asking for a password before it fully boots. I've tried this with every ROM I've installed and every time it will ask for a password. Boot into Recovery, and it will ask for a password there and have all my files hidden, keeping me from doing anything short of a re-flashing my RUU to return to stock. I know these ROMs evidently encrypt your phone during first boot, but I'm at a loss for info on what I'm apparently doing wrong to cause this issue.
Is this an Android N issue? On M, I was able to boot into Lineage, though TWRP still had the file issue. Anyways, whatever help would be fully appreciated. Since I'm a new user I wasn't able to inquire directly on the LineageOS thread, and so deferred to Q&A.
EDIT:
I've solved the issue. After re-flashing the RUU, flashing TWRP, and re-rooting over and over, I figured out what seemed to be going on.
In case anyone else has the same problem as me, here was my solution:
Starting from stock, I went ahead and flashed my phone with the latest TWRP compatible with N (3.0.3.0 at this current time). Afterwards I flashed LineageOS and GApps. As usual, upon reboot, the phone needed a password to get in. So, I rebooted to Recovery, which also required a password. I hit cancel, wiped the phone with a factory reset, formatted all data, and restarted. This did the trick, and I've been running LineageOS 7.1 with no problems whatsoever!
Which version of TWRP are you using at the moment. If you're on N firmware I'd recommend to use 3.0.3-0, that is to be found on the download tab of the TWRP thread.

Installing cm will encrypt your device, was you encrypted previously? Then you would have created a password to access your device.
In my case, I formatted data and then flashed my sense rom (venom) I chose not to encrypt, cm doesn't give this option when you flash it so you have no choice at the time. So if you don't have the password and the device has been encrypted you'd have to format data, don't jump into that just yet though.
Unless someone else knows a way around that, personally I couldn't. However I did have a rom installed so I could boot the rom and back up my data once in the OS. Then format (not wipe) and then reinstall the rom.
Sounds confusing, to be sure we need more info from you.
Do you have an operating system at the moment? If you do then back up your data so that's safe.
Do you know the password to decrypt your phone??

Turns out formatting the data was the solution. Thankfully this phone is brand new, so there was no data to lose.
As for why Cyanogen and Lineage automatically encrypt without giving some sort of default password, I have no idea...
Thanks for the help, though!

Could have thought of that myself. Encryption used by Cyanogen/Lineage is different to HTCs encryption used on Sense based ROMs. Thanks for your feedback.

There is no password and I've had it out in the cm thread, apparently it's common knowledge, which we've both found out its not, there is no password either so you did what was required.
Also, click thanks instead of saying mate [emoji6]
Glad you're back up and running.
thanks had same issue when installing Lineage 14.1 nightly on my HTC 10 today, which already had twrp on it and the stock rom - your solution worked.
i.e.
turn off device
hold volume down while pressing power for few seconds
choose reboot to bootloader from menu
choose boot to recovery mode
hit cancel when prompted for password
choose wipe from twrp, use default options
reboot
no more password prompt.

I need some advice on downgrading from MM, rooting etc

My T800 is in a right state. I was running one of the first MM roms to be released in the wild, with root and twrp. But a couple of months ago, I mistakenly installed the correct official MM rom, breaking everything. Now I can't root it, install twrp and adopted storage doesn't work.
So I was hoping I could downgrade to lollipop, root, install twrp and then update to one of the root-friendly MM roms on here. Is it possible to do that?

By "broken" I mean, apps crashing, apps not installing, freezing, random rebooting, overheating. The sorts of things which drive you mental and, in effect, break everything.
I must have wiped and installed the OS a dozen times over the weekend. I was able to get the correct version of twrp and install it with odin, letting me wipe the system and data partitions in order to get a clean install. I restored all my apps, installed a system update. Then I installed twrp again, flashed the su zip and for some reason it would start freezing, reporting the sd card had been removed. So I eventually wiped, installed the rom, and then let Smart Switch install the correct version of MM for my tablet and just installed the really essential apps. Then twrp and finally su. I was even able to set half of my sd card up as adoptable storage (using root essentials app) and it is working perfectly now.
But I think its time I was looking out for a replacement tablet now. Although a great device at the time, and for a couple of years afterwards, it has become a bit long in the tooth lately.
In order to rule out any external issues, I'd use odin to flash the factory firmware (this of course will erase TWRP). Remove the sd card, and use the device for a while as is. If it works, then your past problems were some kind of software-related problem. If it still has issues, then there could be a hardware problem, like memory or the rest of logic board.
