[Q] Switch from 4EXT to CWM ? / Flashing boot.img ? (CM10-alpha)

Hi XDA
My device before the procedure : HTC Desire S, unbranded, Bootloader locked,
HBoot 2.00.0002, S-ON, ICS stock rom via HTC RUU tool
I unlocked the bootloader via htcdev.com.
After hours of reading and testing "everything" I found here on xda (great stuff!!),
I finally managed to have a running CM10-alpha.
(http://forum.xda-developers.com/showthread.php?t=1776256 / Version 2012-09-17)
As I am new to this flashing stuff, I first tried to follow the flashing guide
on the CM-website. Was not workable because "Revolutionary" can not be used on hboot 2...
So I continued with flashing CWM-recovery and after a wipe (factory/reset/cache/dalvik),
I flashed CM10.zip and gapps.zip.
It went through without any errors, unfortunately, the device did not boot afterwards.
I found this guide :
http://forum.xda-developers.com/showthread.php?t=1525100 (CustomROM with 4EXT-recovery)
It indicates flashing "boot.img" (from the CM10 zip-file) as a last step.
Probably the most important step for this HTC device ?!
The Desire S booted CM10 without any further problems and is running since.
(I did not flash GApps.zip, just downloaded Maps and Youtube.)
I have 3 questions :
1. Is it possible to update to a newer version of 4EXT-recovery without losing
the CM10-installation ?
(e.g. 4EXT-Touch : http://forum.xda-developers.com/showthread.php?t=1377745)
2. Is it possible to switch from 4EXT to CWM-recovery without losing
the CM10-installation ? I would like to have CWM because I could then use the ROMManager App.
(e.g. http://forum.xda-developers.com/showthread.php?t=1484753)
3. If I would stick with the current 4EXT-recovery,
do I always have to flash "boot.img" as the last step before booting up the device ?
(e.g. after the next CM10-alpha release)
"fastboot flash boot boot.img"

Thanks so much !
CM10 is great, so much faster than HTC-stock rom ICS (with Sense 3.6) !!
CU

1) yes
2)yep
3)si
Edit: you only have to flash the boot.img when the kernel changes from cm10 to fallout yes.
Updating cm10 no, if the dev didn't change the kernel.
After a full wipe (in 4ext format everything exept SD-card) you also have to use fastboot. Because that wipes the boot.img

Thanks !
Just to recap, I can flash CWM-recovery and then do a normal bootup (with my existing CM10 installation). No further actions required !?
As the kernel will probably remain at v2.xx with the next CM10-alpha-release of nik111, I only wipe reset/factory/cache/dalvik
and then flash the new cm10.zip.
I do not think that I will format anything. But if I would, I would have to replace boot.img again.

Changing recovery will not touch anything else on your device. But there were some issues reported with CWM on some ROMs.
I think one of them is a lack of /system/lib partition support, which is important if you go from a ROM that has such to a ROM without one (it will end with two conflicting /system/lib directories and the device will not boot.
Also I am not sure that CWM wipes the .android-secure directory on the SDcard which can cause issues if going from AOSP to Sense ROM

For some reason I never changed from cwm to 4ext whilst I owned a ds but I can confirm it does wipe .android-secure on the sd card

I have used it about an year ago so it is definitely improved. But there was an user with Bluetooth issues after flashing my kernel and changing the recovery solved it. Also 4EXT has a lot of minor but very useful settings over CWM. Anyway the OP can try both and stick with the one he likes more
Btw Rom Manager can be used to check for updates and ROM downloads with 4EXT if you choose "manual flash override" from the menu

Nk111 uploaded a screenshot today, that shows kernel v3.0.16
When upgrading cm10 wiping cache & dalvic cache should be enough. If you get any problems, apps fc or something like that, do a full wipe(I use format all partitions except SD card in 4ext, after that don't forget to flash the kernel with fastboot).
Btw wipe and format is the same.

Bug in CM10 Alpha by nk11
Hello XDA,
Sorry if this question is in the wrong thread.
It is regarding the cm10 alpha port by nk111.
I got it working, save one major bug, the speaker does not produce any sound output whatsoever:
This applies to ringtones, alarm tones and music.
The sound is perfectly audible through a pair of earphones.
I followed the steps in the official thread to delete the file /system/lib/hw/audio_policy.msm7x30.so and reboot
but this only aggravates the issue by disabling all audio outputs!!!
I am running clockwork mod v5 with HTC bootlocker unlocked, S-ON.
Any help would be greatly appreciated.

Thanks for the hint with wiping only cache&dalvik.

How to go back to Original OS after CM10 ROM?

Hey guys,
Is it possible for me to go back to my original OS after I upgraded to CM10 using twrp? I still want my phone to be rooted if possible.

NP. i actually had to put mine back to stock a few months ago but i totally forget how i did it now.. i thought my phone was bricked at that point and i was freaking out lol somehow got it working again tho i always keep a backup now just in case :|

I want to make sure I have everything covered here before I do this. I rooted my phone using TWRP & I am using CM10. I want to go back to the original OS but keep it rooted. What is the process exactly that I need to do? I went to this thread and downloaded the file that I needed. My issue is what is the process? Do I move the file onto my phone and FLASH it just like I did with the ROM? Is there anything I need to type in the CMD prompt? If someone could give me some info or point me in the right direction I would really appreciate it! :laugh:

This was my method:
- Download a stock rooted rom
- back up SMS, contacts (super backup)
- back up APS (titanium)
- shut down phone
- boot into recovery
- create backup of entire ROM
- clear cache
- clear system
- clear data
- flash stock rooted rom
- clear cache
- reboot system
- restore apps
- restore contacts/SMS

Sir, a million thank you's. I will do it that way, I just wanted to make sure I had everything set correctly.

I am having a problem, i followed your instructions but when I flashed the stock ROM and rebooted, it just hangs at the HTC screen with the RED lettering at the bottom. What am I missing here?

Before rooting, did you run the 2.20 RUU, and have the newest bootloader? if so, you need to flash the boot.img through fastboot.
If the above statement isn't the case, then try a full wipe and re-flash

To clarify, the step "clear data" is done by selecting "factory reset" in TWRP under "Wipe". Don't wipe SD. You should always factory reset when flashing a new ROM, and also wipe cache and Dalvik.
Flashing a stock rooted ROM is same as any custom ROM. If you had to flash boot.img separately when flashing CM10, you have to do it going to the stock rooted ROM also.

+1. If you had to manually flash boot.img for CM10, you will also have to flash boot.img for your stock ROM. This sounds like your problem.
I also heard that there are some issues with flashing the stock ROM with TWRP 2.3.x--I'm not sure if this is true or not, but it's something to consider.
If you're not getting anywhere, your easiest option would be to just run the RUU. This requires you to re-lock your bootloader first, however (option available in bootloader menu). If you follow this method, you can easily re-unlock your bootloader with the same token from the first time you did it.
For more on running the RUU, see http://forum.xda-developers.com/showthread.php?t=1814217

all official twrp versions http://techerrata.com/browse/twrp2/evita
only versions worth using are 2.2.2.0 and 2.3.1.0 i would save both of them to be able to flash all roms and mods offered for the evita.

[Q] ViperS 3.1.2 + Sensation XE

Hi.
I want to switch to ViperS 3.1.2 but have few questions before I do so. I've never done it before so I'm new to this.
Does it come rooted (or do all ROMs come rooted)?
Is there any instruction on how to do it or just flash it from .zip via the recovery mode (I have CWM 5.x.x installed already)?
And are there any bugs with it such as Wi-Fi problems/tethering, or calls (speaker)?
Also, what if something goes wrong? I've got a backup of my current ROM (stock), so do I just flash that one back or try ViperS' in case it was a mistake on my side?
Lastly, I've heard some people mentioning OTA updates. I'm assuming it's done in the same way as stock ROMs, so you just need Wi-Fi/working internet and the new update will install on its own, or do I have to download the update from here and then do it myself?
Thanks!

Are you S-Off or S-On? If S-Off then you can flash the zip directly from recovery and if you're S-On then you gotta flash 4EXT recovery first and enable smart flash feature and then flash the zip file.
There are no major bugs in the Rom except the ones listed on the OP of the official thread. Enjoy flashing.

I'm S-Off. I've had root earlier but I've installed SuperSU and accidentally pressed Clean SU which has pretty much wiped it. :|

Post your bootloader details to make things more clearer. Flashing a custom Rom doesn't need root access. You can flash it as you're s-off.
What Rom you're using currently? What firmware?

I apologise for not posting, although it may be a bit too late now since I'm already installing the ROM.
So, just wanna know now - do ROMs come rooted, and if I can always go back to stock ROM as long as I have the boot.img/download stock ROM from HTC site?

Most roms come rooted, and the rest provide root tools so you have a choice while flashing.
To return to stock look up ruu. An ruu + s on = your device as it came.

If you had flashed Firmware-3.33 before the ROM - you would have had no "bootloops" at all! The most important thing is to have Firmware-3.33

If you made a backup before flashing you should restore it, or else flash the ROM you had before flashing.
Then use "Titanium Backup" and back up your messages (your contacts are automatically synced with your google account, unless you saved them on the phone, but you can change that with the "people" app.
after you backed your phone up, make a full wipe, and flash the new ROM. Install Titanium Backup and restore your messages backup.
Good luck.

Get a download of the ROM you had before, and you can flash it normally. If you had stock, find a download of stock ROM (although Sense 3.6 custom ROMs might actually work too).

Oh no, I thought you wanted to flash viperS. Flash the ROM you had before flashing, whichever ROM that was (but flash that specific ROM, not a different one. My advice from the previous comment was if you came from stock ROM). If you flash the same ROM you don't have to wipe, and then you can back up your phone.

I hope you can operate adb, because the solution I found requires it.
Go to recovery, and use adbto pull the contacts database with the following command:
adb pull data/data/com.android.providers.contacts/databases/contacts.db
It might give an error for a protected directory (but I don't know since it's going to be done in recovery), if that happens, use 'adb shell' and then 'su'. then exit, and you have root access to the device (do it only if required).
Once you obtained the file, it should be on your adb folder. you need to open it with a database app which supports SQLite3 (I won't reccomend anyrhing since I've never used them. but from a quick search I found a few. and searching in the context of reading android databases would give some recommendations.).
Good luck
p.s - It's hard for me to believe this is the simplest solution. It might work, but it's not easy. So others might give better solutions.

FULL WIPE is clearly recommended when you want to flash another rom. That means (/boot) /system /data /cache /dalvik. You can try it without a FULL WIPE but that will causes errors in most cases.
You need a working HTC USB cable
You need working adb/fastboot, download it from here
You need latest HTC drivers, download it from here
You need a GOOD custom recovery, download it from here
Additionally you need a flashable rom + boot.img
When you got all these we can proceed with flashing a rom

Hello LS.xD,
Thanks for your reply.
I am not at home at the moment.
I will be in about 4.5 or 5 hours, so I will download everything then.
I got the recovery flashed already, so I can probably skip that.
My HTC drivers are probably outdated.
Since my HTC desktop programm had to update the last time I opened it.
And I downloaded the files of the ROM too.

By the way LS.xD,
I got 'CWM-based Recovery v6.0.3.2'. (That's what it says in the top when I am in recovery mode)
I got three wipe options:
- wipe data/factory reset
- wipe cache partition
- wipe dalvik cache
These are all the wipes I got to perform AFTER installing the zip right? Because if you do it before you will wipe the zip file, is that right?

Its for a reason i recommended the recovery in my post. Pls install and THEN we can go on
and NO you first perform the wipe and then install a rom.
and pls uninstall HTC sync before using fastboot to flash boot.img as it will cause errors if you have htc sync installed.

Thats totally safe as long as you dont WIPE or FORMAT /sdcard LOL

Probably a dumb question, but if you do a factory reset your music and pictures will be deleted, why doesn't the zip file be deleted? I will test it at home though. Factory reset, put the zip file on it, then factory reset again in recovery and look if the zip file still exists on my phone.

install twrp without losing data

Good evening, I saw some questions similar to this one in the forum, but none had my kind of doubt.
When a new ROM comes out for both S7 and S8, I install via ODIN using the CSC HOME option, so as not to lose the data.
The problem is in the installation of TWRP whenever I install the same by ODIN, when entering the app and trying to install example no-verity ja start I get the message that the DATA folder has been corrupted and can not be mounted.
This way it only works once again doing WIPE DATA, but then I lose my data and I have to start from scratch.
Is there a way this does not happen or will it always be like this when updating a ROM?
Thank you.

Have you tried backing up data with twrp before you wipe and copying it to your pc so you can do a full wipe then put the backup onto the phone and flash It? You can back up data folder only

Good afternoon,
Thanks for the reply.
So from what I mentioned above, I do a full backup as I normally do, and I also do a separate from the DATA folder.
Then I install the ROM and TWRP, will it corrupt the DATA folder so I restore only it? Would it be this?
If so, will it work out, in relation to being a ROM different from the other?

The main rom info needed is contained in the system folder. The data folder is application data and whatnot. Reboot into twrp and use the backup option, then copy to pc. Do a full wipe of all, pit backup of data folder and new rom on internal or sd. Go into terp and flash the rom and data folder. Do not flaah system or it will overwrite the new rom. u will restore everything even if you don't have the APK installed in your system. It will return the data, you may need to reinstall the APK. Gmail for example will return will email addresses and messages, contacts and texts will come back to what they were at backup. You should back up modem and efs and boot as well and keep them safe. What I do is I get my phone set up fully, all apps I need and any games and data and then back it up again so any issues and I restore it to a fully functional state and don't need to install tons of things

Good afternoon,
I'm sorry for the text I'm using Google Translate.
I believe that I did not understand correctly, because the error happens in the following way, I install a ROM, reinstall the TWRP, yes yes it corrupts the folder DATA!
If I understood mistake, I apologize.

Is it a custom Rom or a stock rom? Also you can backup via ADB

The ROM I use is provided by Samsung, with no modifications, when I install it I use the CSC option the HOME file, in order not to lose the data, and of course, I do not lose anything I only update the ROM.
The problem is that I need to reinstall TWRP after installing ROM, and when I access TWRP it has corrupted the DATA folder.

You can extract the samsung md5 and repack it as a zip with superrs kitchen and then flash it from twrp. Just remove the recovery.img from the extracted files before zipping it up. Then you can simply flash twrp. Then the rom and not have to worry about the fact that you are stuck in a loop of being locked out because you don't need odin for the rom and it won't overwrite your recovery. If that's too much work try using a custom Rom from xda

Thank you very much for your patience. But I'm not clear, or you do not understand.
The problem is not in the ROM, but in the TWRP installation. If I install the ROM with the option CSC HOME I do not lose anything, everything is working correctly.
When I install TWRP it corrupts the DATA folder. The problem is there!

I was saying to use a zip rom because then you can reflash the rom without reflashing twrp. So you flash twrp, it says data error and then you flash rom from zip, which reinstall system and data but will not copy stock recovery over twrp. So you will not have to reinstall it and be stuck. Or try a different version of twrp might also help. Stock firmware overwrites recovery and the rom. You need to modify it to remove recovery from the firmware, or use a custom Rom to stop it from erasing twrp

I think I understood, more or less, since I translate for Google.
But assuming I want to use normal ROM, you have to back up the DATA folder before installing the ROM and after installing the new ROM and TWRP, restore only the DATA?
Thank you again.

Yes a new rom will overwrite data, you need a backup before. You should be able to connect your phone to a linux operating system and use adb to connect and back it up, if twrp will not let you take a back up.

In my case I can back up the DATA folder by TWRP. Is there doubt, if I back up the DATA folder in one version of Android and then restore in another version, will it be compatible?

Yes it will be, marshmallow and nougat are completely compatible from the boot loader up. You can also turn your stock samsung md5 into a zip file so you do not need odin to install it. You will be able to flash it from twrp

You are welcome. If you want to have a stock zip file instead of the md5 use this link.

Can you not read the website?

I know what you mean. Twrp can't access the data folder because it's encrypted. But you do have to format it to gain proper access. You have to copy the files out or back them up

I believe that because I am a new user I can not exclude publications, I already tested in CHROME and IE. In the same way I can not give THANK YOU.
