HELP! To downgrade from FRFR72 to FRF50 - Nexus One Q&A, Help & Troubleshooting

Becasue I have big problems with the volume of the sound, it sounds off randomly and I cannot make it ringing but by chance, I want to downgrade to FRF50. I have the file signed-passion-FRF50-from-ERE27.1e519a24 but I really appreciate some instructions not to bricking my phone.

Did you do a NANDroid backup before loading FR72?

[Q] Little help please...Clockworkmod won't backup system

Hi...I am hoping for an answer here. I have searched everywhere. I don't know if it even matters or why I should really care to do this but I am new to this and it seems I should. I am rooted and running 1.1 update with the stock eclair and have tried to run a Nandroid backup with clockwork, but it stops at "can't mount /system". Can anybody tell me why? or How to make the backup? One answer I saw referred to Gingerbread and EXT4 incompatibility with version 3.0.0.5, but I am in eclair and am running CWM 3.0.1.0.
Also do you really think I need to back up? I have a TiBU for my apps and sys data. I figure if anything goes really wrong I know I can always just redo from stock, just some more wasted time. I guess I am basically asking if there is any real advantage to do a CWM backup anyway at the stage I am at, beside just playing around?
Thanks in advance for any help
From what I understand you get that error until you flash the kernel that came with that recovery. I had the same error until I flashed this zip made by mistar muffin http://forum.xda-developers.com/showthread.php?t=971197&page=21 its the recovery and kernel in 1.
I always nandroid backup, just in case.
I'm stuck in a bootloop and cant figure out a way to boot directly into CWR 3.0.1.0. I tried a few different combinations thinking it would be like the N button and the power but have had no luck. HELP!!!
Still need help? Please
Thanks fro your attempt to help. I flashed 3.0.1.0 from Muffin, but still get backup error, can't mount/system. I have searched for hours for an answer, but there is nothing around about this. Am i the only one with this problem, except previous reply. It doesn't make any sense. I even restored to stock, updated to 1.1 and rerooted, so I would have the simplest system. Still same result. Can anybody help? Thanks
nevermind
Don't know why, but I asked ROM manager to backup and it worked. SO if anyone else ever has this issue maybe this will help.

[Q] stock ics bionic no sound ,hanging,

[B]droid bionic ota ics not getting notifications, hanging badly slowly deterorating . i am willing and wanting to root or reset safely please help traveling for Christmas and need it to work please[/B]
I am having the same issue. The first time it happened, I lost all audio - music, ringtones, phone calls had no sound from me nor from the other party. Phone was extremely laggy and would freeze up then eventually reboot. I was lucky if I could get 5 minutes of use. Sometimes it would happen immediately after reboot. I did a FDR after ICS update and installed all my apps fresh. Many apps "unfortunately, stop" and I cannot get them to work without another uninstall/reinstall. Fortunately, I had a nandroid backup right after the fdr and reinstallation of all my apps. Restoring back to that point has helped tremendously with everything but the audio issue. My music audio still goes out every day or two, but, can be fixed with a reboot now.
Not sure, but it sounds like the hardware is at fault. If an FXZ won't fix it than, I am sorry to say, your phone's dying and no amount of software will fix it.
Just remember, only the ICS specific FXZ file will work for an ICS phone. Any others will be disastrous.
reflash reflash reflash. fxz i always start from scratch, why beat around the bush
I tried to fxz back to stock using HOB in order to upgrade to ics and it kept failing on the final reboot. I was finally able to update by installing the update from .zip file in recovery mode. I read the HOB instructions numerous times before and after and if I was doing something wrong, I cannot determine what it could have been. There is another thread of someone having the same issue after fxz'ing successfully with other devices, so, sounds like some devices may be problematic.
If an audio driver was corrupted. Would a FDR followed by restoring a nandroid backup potentially fix the problem, or, would the corrupted driver be in the backup file?
Well I bit the bullet and did a nandroid backup, then performed a FDR, then restored the backup (yes, the one I was using while having issues). I have had no sound hangs (used to be daily) or any other issues for 4 days now. Also, battery life seems significantly better, especially when idle. My battery was draining like crazy before. Might be worth a try and you have nothing to lose but a few minutes of your time. I didn't do fxz because I couldn't get my phone to fxz successfully when I wanted to do the ics update.

Soft Bricked ... stuck in a loop =/

So sorry for having to ask ... I have managed to get my One (ATT) version stuck in a boot loop. I cannot seem to find anything to restore from in CWM and the only thing on the SD card currently is the custom ROM I was attempting to flash ... I really don't know how to fix this, if anyone could help me I'd really appreciate it. I did some searching around and haven't found a solution to my specific problem, even though others have soft bricked theirs, it seems their fix was much more simple than mine.
I'd love to help, can you explain what rom you were flashing and what went wrong? Did it get stuck in aroma installer?
You should always perform a nandroid backup before doing anything for future reference.
Sent from my Tricked out HTC One
Thanks for the quick reply. I was flashing Android Revolution HD. However, when it was complete I attempted to use Titanium Backup to restore my contacts etc. Apparently the ROM didn't like some of the things I attempted to restore as it conflicted. Like Blink Feed didn't work any longer, just a blank screen where it once was. I decided I would try and re-load the rom again via CWM and went through the wipe process. However, before I went through that I believe I accidentially unrooted the phone by selecting fastboot? Before I got into recovery. Now, if I try to re-load Android Revolution ROM .zip via CWM, it will become unresponsive halfway through the installation. I am pretty sure CWM re-rooted my phone for me as I saw a message asking if I would like to do so and I selected yes. So as of now, I'm just stuck and unaware of what I need to do to fix it =(

[Q] HTC One O2 OTA Update when rooted?

Hey all
This has almost definitely been asked before but I've had a look round and there's so much information out there that I'm totally confused so hoped someone could help.
I keep getting a pop up asking me to install and OTA update to Android 4.3. I'd like to do this but worried that I'm going to do some damage as my phone is rooted.
I am not concerned about losing root (in fact I'd like to lose it) but I'm worried that I might brick my phone when I install the update. Is there anything I should be aware of or an I go ahead and install it?
I'm in the UK and on O2.
Any advice would be gratley appreciated.
Thanks

If you're running custom recovery you can just make a backup of your current system and flash the OTA, and if there are any issues restore the backup.

Well not exactly ...he'll have to flash stock recovery to take the OTA
but backing up before making any changes is always a good idea.
So... make a nandriod backup
copy it to your pc
flash stock recovery
download and install the OTA
Flash back your custom recovery and enjoy

I have a problem with my phone wanting to update to ZV6

So about 3 months ago when i got my phone i used titanium backup to freeze my system update app, and i then rooted my phone. Today i wake up and my phone tells me it wants to update to ZV6 from ZV5, now i know that if i update my phone being rooted that i risk bricking it. So my question is can i use the ZV5 restore to reset my phone even though if i reboot the phone it might update or how should i go about reseting my phone to stock before updating it, or how should i go about unrooting so that it does not update on me and brick my phone. Any help will be much appreciated
just an update really quick
So going through my system i have found the update.zip file that matches the size the update screen is telling me about, what i wanted to also know is can i just cut the update.zip to my external sd card and that way i have a backup and then when i get home reboot my phone into recovery so that i can restore it to stock, and not risk it updating on me if i dont press the button fast enough. I really need some advice here cause i do not know what i can and can't do with this phone. i used to mess around with an s4 alot before so i have a really good understanding of how to find things in the system, so any advice is good advice. so just let me know thanks a bunch
