[Q] Amon Ra Recovery or ClockworkMod Recovery

Evening All
I'm just curious as to what which people are using at the moment.
On my G1 and initially on my Desire I used Amon Ra, but people seem to be talking a lot more now about ClockwordMod.
Which do you prefer and why?

i prefer clockwork, but, only as i dont understand how to set up amon ra and and use it so ive never had chance to test it.

I am using clockwork it was a one click op with unrevoked

Me too i used Clockwork, id like to try also Amon Ra because is similar recovery of Hero that i used soo much time.

I just love ROM Manger app so clockwork mod came naturally for me.

nobody AMON RA?

I'm using Amon RA!
...love MS USB Toggle

USB feature id hidden but working in Clockworkmod, me find no reason to AmonRa!

Using amonra cause of partitioning SD card is damn bad in cwm recovery
Sent from my HTC Desire using XDA App

No one using both? xD
I have AmonRA flashed directly as recovery and Clockwork as update.zip so when you get to recovery it loads AmonRA but you can flash SD update.zip and it loads ClockworkMod.

How did you do that? I thought there was a feature on RM that let you flash alternate recoveries. And, if I flashed CW it would show me the option to flash Amon Ra if I wanted it.
I have Amon Ra, it is bullet proof. But, have thought about both. CW seems to have more issues.
Anyone have good detailed info on how to use both?

Amon Ra too, coming from a G1, its a more familiar recovery to me

What I did is install Clockwork Mod as it comes with the update.zip and flash Amon Ra with unrevoked. Despite unrevoked comes with Clockwork Mod, you can start it before plugin the phone to the PC and select which recovery you want to use (select the file), so you can download Amon Ra, select if with unrevoked and flash it as custom recovery. If you keep your Clockwork Mod update.zip you can launch Amon Ra as default and select flash SD update.zip to launch Clockwork Mod.
BTW, unrevoked needs a Sense UI ROM. I tryed doing this with OpenDesire and didnt work so if you're not using a Sense UI I suggest you do a Nandroid, flash a Sense UI, do the unrevoked thing and restore the Nandroid back. Its kinda pain in the ass but it works...

Thanks,
I know I am on a desire thread, I have an N1. But, will look at the zip stuff.
I thought for me I could install CW and see my amonra recovery in the "flash alternate recovery" box. Then flash whichever recovery I wanted. If amonra, flash it and back out of CW and use amonra as usual.
Sounds too easy to work.
Ken

AzureusPT,
Please let me know if my previuos post is correct, or do I need to do what you did.
If so:
1. Does CW automatically get put on SD when you flash it thru Rom Manager as a .zip?
2. How do you make AR default? And get back to it after using CW. Just reflash it thru the "Flash Alternate Recovery" in Rom Manager?
Ken

clockworkmod, very easy to use

Got it all figured out.
Clockwork and Ra working fine together. Alternating recoveries very easy.

Flash the Amon RA one through UnRevoked 3 and then put the ClockWork Recovery on the root of the SD Card as Update.zip (via fake flash). I have this setup but to be honest Amon RA is superior so I hardly ever use the clockwork one

You should Odin back to stock! Check the dev section. I'm sure there is a thread with stock rom and recovery.

Odin would be the only way. Correct.

Nope i cant i dont even know how this problem came along i was using a stock root then i decided to install CM 10 and when i tried to back it up i started getting this problem :l and i dont know how to return to stock i downloaded that SAMSUNG GALAXY S3 TOOLKIT would that program be able to return me to stock unrooted.

Can someone point me to a link that will help me go back to stock unrooted. Like the phone was straight out of the box?????/

You should do your backup directly in CWM and not ROM manager. Go to backup then back up in internal storage. I'm on touch 5.8.4.5 and back up directly in CWM then rename manually in Rom Manager. Just download a stock rooted ROM and flash it in CWM. Can you mount sd card in CWM? Just download a ROM then mount sd card and copy then flash after will ng data and formatting system and wiping caches. I would personally Odin back to a stock ROM, its easier.

Try to back up to your internal sd card instead after that error message by using the backup and restore menu in recovery mode. That happens to me when i try to use the ROM manager backup method because my ext sd card is full

You can have custom recovery and not have root. Go to your app drawer and if SU or superuser is not there then you are not rooted.

Okay so i flashed stock recovery via oden then i flashed the stock rom .tar file via oden. then after my phone was back to stock i re-rooted it and flashed cwm my phone is no longer getting that message but it still isnt backing up to the sd card ??? can someone plz help me

Problems with Titanium Backup

Hi mates Im having problems restoring my apps with titanium backup.
I did a complete backup when I was on B122, it created a folder with the backup files I guess the apps are in the com.developer.nameapp.number.apk.gz files.
Then I installed the B118 chinese ROM and the clean ROM.
When I try to restore the apps and data only appear data files, no apps, so I cant restore them.
I've tried to restore manually installing them with ES File explorer but it says invalid file type, the gz one.
Please, help me

Are your apps backed up on your SD card? You probably just need to change the location of the backup folder. Go to menu > preferences > backup location settings, then select "detect", if it's not in the correct folder.

Don't. There is a 75% risk of bricking your device. Today one guy just bricked his device going from B122 to b188CN and mentioned it on xda.
If you want to anyway take the risk, then go to official B111 and then to b118CN.

No need to go back on B111 now. That was just a suggestion because no one yet reported getting bricked when moving from B111 to B118CN, although on the other hand it could be that not much people moved from B111 to B118.
Btw, how did you upgrade to b118 ?

when I go into Titanium, I can't see all the files in the backup folder, only data ones with the check symbol, not the face one.
I tried this on HYD52ROM not on B118, is there a way to go back to B118 from HYD52ROM?

If you have the permanent twrp recovery, then you'll need to install the stock recovery. Then, do a forced update within the stock recovery.
EDIT: if all the files are there, then maybe try clearing the data of titanium backup, in app manager? If that doesn't work, then it might just be the rom itself.

hmm, I'll try later with the clean rom...

nothing... for example I installed google authenticator, restored its data and then the app closes unexpectadly

With some apps, you can't restore data. It causes issues sometimes. Are your other apps being restored successfully?

Saves you a lot of stuff if you can do the following : install stock firmware B118 CN , than flash TWRP Recovery and and do not forget to make a backup on TWRP including also cust partition ! ( save backup on external storage ) ! In this way you can restore the stock firmware b118 without hassle if something goes wrong...:good:

Finally I managed to restore all the authenticator apps so I dont "need" to restore.
I guess its all about corrupted data because of the crappy format fat 32..

[Q] I got sent an unlocked M8, how to go to default install?

Hi,
Rogers sent me a refurb M8 but the problem is it's unlocked and it shows these at the startup (at the end of the post).
How can I restore this to default locked or unrooted version where I don't see this kind of stuff? I just want the default setup. The phone asked me to install the newest android and I accepted but it still shows the same startup which prevents installing the update automatically as it would otherwise.
I went to restore and I chose this update (I think) myself and now after the install, my phone is stuck in this looped animation which starts with "google" and then you see these 4 circle like shapes moving into the center and away forever. What should I do?
Thanks.

obviously not much refurb done on it if it has unlocked bootloader and custom recovery....

Thanks I could do that but they sent this to me accidentally so I want to keep it. My old phone is M7. But the problem is I don't know what I need to do.
I followed the method 2 here but I don't know how to initiate the custom rom installation, it doesn't start:
http://www.droidviews.com/restore-sprint-htc-one-m8-to-stock-rom-with-ruu/
Choosing HBOOT, shows a different menu, doesn't do anything.
Any ideas?
Thanks.

That is not a custom ROM installation, its the RUU for the Sprint variant.
Its a good thing it didn't start, as the Sprint and Verizon versions are CDMA, and installing anything for those versions might brick your phone. I strongly recommend you not follow anything from that webpage.
Also, on the hboot screen, does it say S-on or S-off? What hboot number?
You should go to the following thread, get the nandroid for Rogers, flash in TWRP. Then get the corresponding stock recovery and flash in fastboot: http://forum.xda-developers.com/showthread.php?t=2701376
You will also need to install fastboot, and I think this is probably the easiest and least painful method:
http://forum.xda-developers.com/showthread.php?t=2588979
I can understand why you want to keep this phone. But to do what you are asking, you will have to be patient and do some learning . . .

Thanks alot, I don't mind some learning but I have a week to do this and then try out the phone so I can tell if it works. So then I can return my original phone. Otherwise they would charge me the full price of the phone.
Ok so on the hboot screen, it says s-off.
Hboot version is 3.16.0.0000.
So nandroid is someone's backup right? How do you flash in TWRP? I think using Hasoon2000s app, I installed ClockWorkMod because that's what I see now.
You mean installing fastboot on my PC? Because I think I did that as I can use that command and my phone boots.
Is "1.12.631.17 - TWRP" nandroid a good one from the first link you posted?
Lastly when I do this, it will basically have this OS, right? But will the TWRP, etc stay? Because I thought it will be like formatting my PC where everything is gone and all I have left is factory stock sense.
Thansk again.

Correct, its a nandroid somebody else made. Its meant to be "stock" and for anyone to install (assume it contains no user data). You install by placing the backup in the appropriate folder (if TWRP, find the folder TWRP on the internal storage, and you will see subfolder called "Backups" and inside a folder with some random looking letter and numbers (mine says HT. . . .). Its inside that folder, you want to save the downloaded nandroid file.
Once the file is saved to the right place, TWRP will just think its a backup you made. So select "Restore" in TWRP and select the appropriate file.

If your recovery is CWM, select the CWM nandroid. If your recovery is TWRP, you need to select the TWRP nandroid. The 2 recoveries work differently, so you can't restore a CWM nandroid with TWRP, or vice versa.

If you have fastboot installed on your PC, then you are all set. I just assumed you did not.
Fastboot is only needed to install stock recovery (after restoring a nandroid), if you want a truly "stock" install.

Its the nandroid that has the stock Rogers software, yes. As mentioned before, you need to have TWRP recovery if you want to restore the TWRP nandroid file.

You will still be on custom recovery. The nandroid doesn't include recovery.
It not like formatting a PC as you describe; because on the phone, recovery and a lot of other things (radio, bootloader, and more) are on separate partitions. A nandroid restores the system (OS), data (user data) boot (kernel) partitions. The other partitions are left untouched.
If you want to restore stock recovery, you can do that as well as shown in the link I provided (same thread as the nandroid backups).

Wow thanks alot man, I understand it alot better now.
After I do this though, and the phone installs a new update for me, will I be able to install it?
Because right now when that happens and I say "install now", it restarts and shows TWRP but from there I don't know how to install this update. I am used to selecting "install now" and the phone would automatically install it at startup. I want to have this behaviour if possible.
Also how can I restore the stock sense after restoring the nandroid?
PS: I just restored the nandroid but when the phone restarted, I see my old OS, i.e. same wallpaper, same apps I have, instead of seeing the startup wizard. I assume I won't see the startup wizard but shouldn't it be a brand new OS like you said? So it didn't work?
TWRP said it restored successfully in 126 seconds.
Thanks again.

Any ideas?

Which nandroid backup did you download? You must have also the same recovery. But let's take it one step at a time. Let us know which nandroid you downloaded and we will take it from there.

Can you open the zip file and tell me a bit the folder structure? You will need xopy this folder to your external sdcard and from TWRP you go to Restore and select the folder from the sdcard to restore the nandroid.
It's not a flashable zip

Thanks I am not home right now but it had a few files. I extracted the folder to my pc and then copied the folder. I saw it in twrp and then it restored it correctly. I mean I saw the nandroid there in the restore list. So I did that correctly right?

Yes this is correct. Now if you flash stock recovery 1.12.631.17 you are stock and ready to receive OTA from HTC

First of all factory reset...It will reset your rom and you will be completely stock ready to setup like new.
Then to get rid of the custom recovery, download the recovery from here:
http://d-h.st/sQF
Paste it in your fastboot folder and reboot to bootloader.
then run this command.
fastboot flash recovery stock recovery 1.12.631.17 recovery.img
Reboot and you are set

Thanks alot man, I will try this tomorrow and report back asap. But by fastboot folder do you mean the one in the Android folder or somewhere else?

[Q] Reverting to Stock GPE Kernel without using an RUU?

Hey guys,
I'm currently on a fully GPE converted phone running stock Lollipop 5.0.1.
I have S-Off, root, TWRP and Xposed.
I'm planning to flash the Quantum kernel on my device mostly to get KCAL support (LCD color switching), but also for the supposed battery improvements.
I'm obviously going to take a TWRP Nandroid backup prior to flashing the kernel so that I can restore back if something goes wrong. But what I'm wondering is, if I decide I actually want to go back to the stock kernel at a later date (say in a month), is there any way to flash just the stock kernel or back up my current one? I can't seem to find a copy of a stock GPE kernel, can I compile it myself or something similar? I'd prefer not to have to do a TitaniumBackup and use an RUU since that's such a load of effort.
I'm a software engineer so no need to sugar coat any technical details for me.
Thanks!

I have S-Off, root, TWRP and Xposed.
I'm planning to flash the Quantum kernel on my device mostly to get KCAL support (LCD color switching), but also for the supposed battery improvements.
I'm obviously going to take a TWRP Nandroid backup prior to flashing the kernel so that I can restore back if something goes wrong. But what I'm wondering is, if I decide I actually want to go back to the stock kernel at a later date (say in a month), is there any way to flash just the stock kernel or back up my current one? I can't seem to find a copy of a stock GPE kernel, can I compile it myself or something similar? I'd prefer not to have to do a TitaniumBackup and use an RUU since that's such a load of effort.
I'm a software engineer so no need to sugar coat any technical details for me.
Thanks!

Download the GPE ROM, unzip it, and look for the boot.img. That's your kernel.

Thanks. Could I just restore my TWRP Boot backup for the same effect?
Otherwise, in terms of flashing the boot.img, is it just a "fastboot flash boot boot.img"?
Edit: Also, slightly off topic but how does a recovery flashed ZIP know to replace the kernel and not flash to /system instead?

You could restore boot from your backup. I've never done it myself, but I'm sure it would work fine.
Fastboot flash boot boot.img is correct.
The zips are broken up into appropriate folders; be it ROM or backup; that are directed to the proper partitions during the flash in recovery. I've never delved into it too much, but I'm sure they have something like [flash-boot] [/flash-boot] written into it.

I just unzipped the Quantum flash ZIP and noticed that it also seems to flash a bunch of files to system as well as to boot.

Would I be correct in assuming therefore that I would need to flash both boot and system images from the GPE RUU to get back to the stock kernel? To save having to re-flash system could I just open up the system IMG and extract the files that were replaced by Quantum?

Do a full nandroid backup and, if you wanna go back to what you had before, restore it. As you're correctly found, there are some system modules required to work with the kernel so just flashing the stock kernel might not work

Was hoping I could get back without the full backup. I've done the flash now and let's say for example if I want to switch back to the stock kernel in 1 month's time, using my nandroid backup would lose me a lot of data, I'd be better off just taking a Titanium Backup, flashing the RUU and restoring, but that's a massive pain as well.
Would my idea of manually replacing the system partition files that Quantum modifies with their stock variants, or deleting them in the case that the stock variant has no such file, work?

Yes, in theory, so long as you can get them all. Remember a Nandroid won't touch your personal data but might affect any app data but it's ALWAYS recommended to make a backup so at least you have something to fall back in should the worst happen

Don't worry I definitely took a backup, and I'd restore if things had gone wrong immediately (boot loop, etc.)
My concern here is more so for what happens if I decide after a month or so of usage that actually I don't like Quantum and I preferred stock (battery life worsening, etc.)
Thanks for all the help.
