[Q] Help with root and custom ROM.

Hello guys,
I've been looking around hier for a while, and I spotted a Custom ROM that I'd like to try, it's this one: http://forum.xda-developers.com/showthread.php?t=1424260
I've never rooted my phone before so I don't have experience with it.
I found a couple of threads that can help me but, I don't know in wich order I have to follow them.
First of all, I'd like to make a complete back-up of my current ROM, so in case something goes wrong, I can restore it. How do I do this? I read something about ClockWorkMod and a nandroid back-up, can somebody clear this out?
I have an unrooted HTC Incredible S with S-ON. So first, I think that I have to get S-OFF? I found a tutorial with the Revolutionary tool, but it doesn't support my HBoot, so I think that's not an option?
So then, I found this tutorial: http://forum.xda-developers.com/showthread.php?t=1337105
The tutorial is easy to follow, but can I create a full back-up before I start the tutorial?
And to get S-OFF, do I need a rooted device?
I hope somebody can help me. If you need more information, just ask.
Here is some information about my device:
- Android 2.3.5
- HTC Sense 3.0
- S-ON
- Not rooted
- HBoot 2.00.0000
- No SIM-lock
If more information is needed, please ask.

Unfortunately having your current h-boot the method available to you to root and install custom ROMs does not let you back up your phone prior to flashing. As the method used is flashing a new ROM that allows root access to your phone. Prior H-boots (1.13.0000) allowed you to root your phone without flashing a custom ROM thus unlocking boot loader to be flashed CWM as a custom recovery and allowing you to create a nandroid backup of your current state before flashing a new rom. However[/] the process you are going to need to complete might contain a back-up function included in the flashing process, I don't know for sure as I flashed from 1.13.0000, but it doesn't really matter as your going to have to complete the process anyways. I say just go for it and follow the instructions to the "T". If you follow everything properly and take your time you shouldn't encounter any problems.

In the tutorial I posted, step 10 is
10. Using volume up/down and power to select, go down to Backup/Restore. Select it, then hit Backup. ClockWorkMod will backup your stock ROM in case there are any dramas and you want to go back to it.

Will this create a complete back-up? So when I restore it, will everything be back the way it is right now?

Exactly. Stay safe.

So if I just follow that tutorial, I will have a Custom ROM with root? And do I still have to get S-OFF?

You don't need to go S-OFF to flash a custom rom. There is actually no need whatsoever to go S-OFF, unless you want to go and flashing other radios. But the lastest sense 3.0 and android 2.3.5 update included the lastest radio, so keep S-ON. Better for warranty.
First go to htcdev.com and follow the instructions to unlock bootloader. BE AWARE THAT THIS WILL WIPE YOUR PHONE TO FACTORY DEFAULTS for security reasons, sdcard remains untouched.
After bootloader unlocked you can flash the clockwork recovery (you're still S-ON). Once you flashed that you can go into recovery with volumebutton down and power on. Take a backup with clockwork (=nandroid = full image of the phone in its current state) of your original rom and start flashing custom ones.
They're is probably a time where you gonna think you bricked your phone, I have. But I always got through it by searching the forum. Always, in any circomstance, manually push the boot.img of the associated rom from a PC to your phone. So never flash a ROM from your sdcard if you don't have a PC in hand. Otherwise it will probably not boot or get hardware not working (not broken in anyway, just not properly loaded).
Before changing roms, I always do the ARHD wipe script. Just to be sure every trace of the previous rom is gone. There are multiple partitions on your phone (system, data, boot). It wipes all of them to start clean.
The ROMs you are going to flash are rooted by default.
So now, of you go and be a ICS beta tester

Thanks fot the explenation.
But, because I can't root my phone because it's HBoot 2.00.0000; I can't make a back-up of it? Not even with Titanium Back-up.
Is there any way I can back-up my app's? So I don't lose all the saved data in the app's?

As far as I know the answer is "no".
You need clockwork for a nandroidbackup, you need bootloader unlocked for clockwork, unlocking bootloader wipes your phone.
I accidently wipe mine with the unlocking of the bootloader. It seems harder than it is to start over. Just link contacts and calendar with gmail, backup sms on sdcard in messaging. That's all you need. Starting over is good to get the crappy apps gone

Hmm, okay, then I'll have to do it without making a back-up.
And is there an easy way to switch between ROM's? Without using a computer.

It is very easy to change roms. They are stored in zip-format on your sdcard which you can browse to with clockwork. Also the nandroidbackups are stored on your sdcard and can also be chosen with clockwork.
Experience tells me that you still need to flash the boot.img of the rom manually after you flashed the rom (something to do with clockwork not able to write in boot partition while in recovery-mode, you have to be in fastboot-mode). Flashing the boot.img litterly takes 2 secs to upload, done, and reboot.
So it is no big deal to swich:
- boot in recovery
- browse to the desired rom/backup
- start and wait 5 mins
- boot in fastboot
- connect to pc and flash boot.img
- wait 2 secs and reboot
Do not flash when you need the phone and there is no pc around. If it goes wrong, you need your usb pc to fix things.

I heard something about Rommanager, can I use this and what does it do excactly?

ROM Manager is an app that works with ClockworkMod recovery to keep it up to date and allows you to make and manage CWM nandroid backups and manage partitions on your SD card. The paid version also allows you to download custom ROMs and flash them.
It requires root access in order to run.

But it's not a necessary application?

Ok, propably I'll try it this evening.

Thanks for everything who helped me, I followed the tutorial and everything is working fine.

[Q] HTC One (64GB Dev Edtn) keeps crashing even after flashing new roms

To start off, I'll write down a history of my phone's problem. It had me scratching my head for over 1 week already and I still can't resolve it. I've been non-stop searching all over the net for solutions, and unfortunately it's still problematic.
Before the problems started, this is the state of my phone:
Stock HTC Rom 4.1.2 ver. 1.29.1540.3, rooted, custom recovery TWRP.
My phone initially hanged after receiving a text message. So I thought it just crashed and just needs a simple reboot. But unfortunately, after a reboot, it was just stuck at the "HTC quietly brilliant" splashscreen. But it could go into bootloader. So I went into recovery to restore from a backup point. But the restoring process failed, and worse, it wiped my current OS off.
So I went over the net to search for a copy of the stock HTC rom. then I found the specific RUU, from bugsylawson's, for my phone. And, at last I thought, the phone was back to normal. But unfortunately again, when I tried to re-download all my apps from google play store, after installing a few apps, my phone crashed again. the crash would reboot and enter into the OS but after a few seconds, it would hang again and reboot until it doesn't get into the OS anymore.
I went further research and studying about android terminologies to better understand the state and problem of my phone, and I came up with the idea to try to install a famous and stable custom Rom. I chose Android Revolution HD 13.3, which runs a custom 4.2.2 jelly bean. After successfully flashing the rom, I was so happy that everything went back to normalcy. So again I tried to reinstall the apps from play store. and everything worked fine. then after about approx. 18hrs, the problems started to show up again. My phone would hang while I was using it. And it would restart. sometimes it would just force close an app that i was using (in this case, I was using the "Internet" app and camera app). And after rebooting by itself a couple more times, it would get stuck in the "HTC quietly brilliant" splashscreen. again.
I tried several times to re-flash the custom Rom, and it would flash successfully everytime. And just to make sure i did the correct steps before flashing a new rom, I would like to enumerate what I did:
-wiped data, system, cache and dalvik cache partitions
-flashed custom rom via TWRP.
After everything I've tried. I'm starting to wonder if my phone has factory defects. I'm pointing to three parts of the hardware: processor, flash drive or cache. I'm wondering if the cache is a hardware or software based, and if it is a hardware, could it possibly be damaged physically and can't be repaired? How do I checkdisk the flash drive to make sure that i don't have bad sectors in it? How could i also try a diagnostic test of the processor to make sure that it is not faulty and does not overheat?
I'm new to android debugging. I would gladly take any logical solutions to help solve my problem. I'm pinning my hope on this forum before I finally contact HTC to claim a warranty or anything.

Hi can you download TeamViewer so that I can flash the latest 4.3 firmware on your device, after S-Offing

Hi Matt,
First of all, thanks for the very quick reply.
Uhn matt, I don't mean to annoy you with questions. But are there any other solutions without S-offing my device? And if possible and if it's not a hassle for you, may I ask what your possible might be? (Could you please enumerate it?)
I would greatly appreciate it if we could discuss the procedures first before actually trying to fix the issue.

You'll need to S-Off to flash the 4.3 firmware, and you want to be S-Off now as you can't use the exploit on the newer hboots. I will S-Off, flash 4.2.2 firmware, flash 4.3 firmware, then flash 4.3 Sense stock rom, then you can s-on if you want

I see. How is the new Hboot different from the old hboot? And if anything goes wrong, could I still go back to the old hboot?
To what firmware version is it going to be upgraded to? Will it have the same radio?
Just to clarify, we're CHANGING firmware version, not UPGRADING right? Is it because we're changing to different region's firmware so that i could just download an OTA update of newer stock roms? Correct me if I'm wrong.

[SOLVED] updating unlocked\rooted\s-off htc one to 4.3

Hi everyone,
im a newbie android user, have my device for barely 2 weeks.
i have a couple of questions on my mind, questions i tried googeling answers to for days now,
as i didnt find clear cut answers, im asking for your help.
i know i can flash a the stock 4.3 rom using custom recovery (i use TWRP) but that will result in wiping my data.
im interested in updating my AT&T HTC One to 4.3 without losing my data.
note that i currently have an unlocked bootloader, root (supersu) and im S-OFF (used Revone)
i already figured that i need to unroot my device and re-lock the bootloader in order to receive the OTA update properly.
my questions are as follows:
1) do i need to flash back to stock recovery in order to update or is unrooting and relocking bootloader good enough?
2) since im S-OFF, updating to 4.3 will update my hboot but will keep me S-OFF? or will it turn it on? or maybe it wont even update and stay on 1.44?
3) after i update to 4.3, re-unlocking my bootloader will once again wipe all data?
4) after updating to 4.3, in order to re-root my device i follow the same procedure i did on 4.1.2?
5) since im not using an AT&T sim card, i had to flash some wifi files in order to bypass carrier check and turn on wifi tethering, i imagine im gonna have to do that again on 4.3, will the same files work or will i need to wait for a new hack\workaround to come out? (i used: http://forum.xda-developers.com/showthread.php?t=2285047)
i have a few more questions that i cant recall right now, too much google digging for info got me confused.
will add them if\when i remember.
Thanks in Advance.

You don't need to relock bootloader or remove root, you do need stock recovery and stock ROM. Hboot will be updated, S-Off will remain. Your data will not be lost. Follow same procedure for root.

Thank you for the quick reply.
a few followup questions if u dont mind.
1) where do i get the stock recovery files?
2) how can i identify the correct ROM associated with htc one 4.3? i know i need to use Cingular as my HTC is an AT&T one, but the roms versions are listed by AT&T firmware.
3) do i flash stock recovery and then do a regular OTA update?

Just a quick question: why do you want to go through all that hassle to receive the OTA? Since you're S-Off you're able to flash unsigned firmware. The only reason I can think of using OTA, is if someone is S-On and therefore cannot update firmware; an unlocked bootloader allows you to flash ROM, kernel, and radio, but not firmware. with S-Off you CAN do that.
One piece of advice, in either case, DO NOT GO S-ON EVER!
Or did I misunderstand you?

There are files in the firmware.zip that wipe the phone, removing those files means it won't wipe. Often boot.img and recovery.img are also removed from the firmware you download from here.

What do you mean by data? your internal storage/sdcard with pictures, music, etc. or your apps?
When flashing a new ROM with different base (eg 4.2.2 to 4.3) a wipe is recommended (that would wipe your apps and their data, not sdcard), but you could use Titanium Backup, Helium, etc. to back those up and restore.
You can do a dirty flash, which would not wipe your apps, but could lead to some potential problems with some apps; in which case you would need to reflash with wipe.
Anyhow, be careful with going back to stock first, because when you flash the stock recovery, it will/could wipe your phone completely including sdcard. Happened to me while I was testing a few things, and just flashing stock recovery and accessing it, wiped my apps and sdcard.
Hit us with some more details, what ROM (etc.) are you on now, and where do you want to go.

This is where I am now (attached pics)
I would simply like to upgrade my HTC to 4.3
I would like to do that without the hassle of wiping my phone and restoring apps data.
But if it's necessary I'm willing to backup and restore the apps data.
As u said, my SD CARD contents will no be deleted? ie photos, music etc.
From what u guys told me, I gather that doing an OTA is not as simple as I thought.
Can u please tell me the easiest way to upgrade?
or even better, what my options are?

In my humble opinion, you should do a full back up of everything (nandroid, apps+data AND sdcard) and copy all that to your PC.
Whichever way you proceed, you're going to be moving from Android 4.1.2 to 4.2.2+, that will change the file structure on your phone: in 4.1.2 sdcard points to /data/media/ but as of 4.2.2+ it now points to /data/media/0/ (this is due to multiuser support in 4.2.2+).
For some, whether OTA or flashing a custom ROM, three things have happened:
1- the sdcard (pictures, music, etc) files were moved correctly to /data/media/0
2- the files were duplicated in /data/media AND /data/media/0, so they had to manually delete the duplicates (root enabled file explorer needed)
3- the files were not moved at all, and had to be manually moved from /data/media/ to /data/media/0/ (root enabled file explorer needed)
Note: that once you're on 4.2.2+ /data/media/ will no longer show up when you connect to your PC, only /data/media/0, hence why you need a root enabled file explorer to access /data/media/
If it was me (and I like a clean phone ), I would flash the new custom ROM in recovery, then while still in recovery format the /data/media/ (/sdcard/), boot up and let the ROM setup the sdcard as brand new.
And then setup the device from scratch. Copying all pictures, music, etc. back using your PC.
For backup/restore of USER apps & data, I would take a look at these:
* Titanium Backup
* Helium
* SMS Backup & Restore
* Call Log Backup & Restore
and possibly the built in HTC Backup.
Titanium can back up the data of system apps, but it's not recommended to restore these especially between the large gap from 4.1.2 to 4.3; usually you could restore WiFi, Bluetooth and a few more settings, but there have been reports that due to the changes in all of these, the restore of system data could/was causing problems.
Finally, if you want to upgrade your firmware, use vomer's guide here: http://forum.xda-developers.com/showthread.php?t=2365506. The firmwares there have boot.img (so no need to reflash RIM), recovery.img (so no need to reflash custom recovery) removed as well as the files that would wipe the sdcard. So you can flash the firmware without any negative effects.
Of course you could just do all the backups, and try dirty flashing (without wipe), and see how that works out for you. In case you run into problems (eg apps force closing, missing widgets, bad Wifi, bluetooth, or mobile data), you can then reflash with full wipe.
This is all my personal opinion, so don't know if anybody disagrees with my thoughts.
EDIT: if you use CWM recovery, you should also take a look at this after upgrading: http://forum.xda-developers.com/showthread.php?t=1991657

Sounds good. Tyvm!!!
I'd like a clean phone as well.
So lets me know if I get it straight:
1) flash Rom in recovery (after backing up media and/or non-system apps)
2) wiping SD CARD clean
3) flash firmware in recovery
4) flash radio in recovery
Did I get it right?
Again thanks on advance

Yes pretty much, the most important part is the backup, I would do:
1- a nandroid backup in recovery (just in case you want to come back to that)
2- perform a Titanium Backup/Helium of everything (you don't need to restore system apps/data, but it's good to have them anyway)
3- perform HTC Backup (I do it, but have never restored from it yet)
4- copy everything from the sdcard (which would include above) to PC
firmware (modified versions by vomer) and/or radio can be flashed at any time without any risk of loosing apps or sdcard.
You should be good to go.
PS: In case you format sdcard and /system/ and find yourself without an OS (by accident), you will have to use 1 of 3 methods to get the ROM you want to flash on the phone:
1- adb sideload
2- adb push
3- OTG cable

Which firmware and radio version I need?
Whats the modification done in vomer's firmwares? Just removed files to prevent data wipe?

Firmware and radio are pretty much up to you; especially radio, where newer doesn't always mean better, it's very user specific, but you can flash them so easily in recovery back and forth. (I have them on my phone all the time and experiment depending on my location)
Also, just remember once you go to 2.x firmware or above the touchscreen drivers will no longer work with a 4.1.2 ROM, but then again why would you want to go back
The files in vomer's firmware that are removed are:
1- stock kernel (boot.img), otherwise you'd have to reflash ROM.zip after updating firmware
2- stock recovery (recovery.img), otherwise you'd have to reflash custom recovery after updating firmware
3- I don't recall, but some firmware package had a files in them that would wipe the sdcard (but haven't seen those for a while)
Firmware and radios are all available in vomer's guide: http://forum.xda-developers.com/showthread.php?t=2365506

you'll have to do it manually, I'm using CWM, so I have to go to "mounts and storage" and then "format /data and /data/media (/sdcard)"
hmm, on that thought after formatting and booting up your ROM, check if all the apps are there, some get installed to /data/app, and I wonder if the above would delete those.
Wouldn't be a big deal, you would just copy the ROM back to your sdcard using your PC and reflash it. (Maybe do that anyway)
At least you know you'll have a clean sdcard without any possibility of duplicates or other files you no longer need (eg temporary files from some apps)

Alright, I've done it!!!
Upgraded to 4.3 stock Rom, which came with 3.17 firmware.
(used: http://forum.xda-developers.com/showthread.php?t=2476204)
Flashed AT&T OTA radio.
Even found a new tether hack for 4.3 that will allow me to activate tethering while not on AT&T network
Thanks a lot for all the help,
Much appreciated.
One more question tho if that's ok,
Are there any downsides to upgrading my firmware from 3.17 to the latest 3.62?

Congratz.
As for firmware, I can't think of any downsides to upgrading it. Since you're S-Off you can always downgrade it back to 3.17 if you find any incompatibilities, though I dont think there will be any.

Alright ty.
The current firmware I have is 3.17.502...
Which came with the Rom.zip I flashed
I only found 3.17.402... on xda
Would u happen to know where I could get 3.17.502... ??
As I wouldn't want any problems or incompatibilities with the 402 one.
Also should I bother updating my hboot (if it's even possible)??
Thanks again.

Are you sure the ROM.ZIP contained firmware?? Usually, ROM.ZIP only contains the ROM and firmware is separate; also because the two have different flashing methods:
1- custom ROM is flashed using custom recovery
2- firmware is flashed in fastboot RUU mode
can you post a "fastboot getvar all" (remove IMEI and s/n before posting) to see the details.

Many ppl having issues updating stock rooted rom on this update and the previous one. Better to fully unroot the phone before attempting it. Using the 7.17.1540.21 RUU (see the link in my signature) is a good option imo but will wipe the phone unfortunately. Better to do a nandroid backup before updating (and copy the backup on your PC). Worst case, the update will cause a bootloop and you'll have to flash the 7.17.1540.21 ruu.
Might worth a try to backup your /data partition using twrp (save your backup on your pc), flash the 7.17.1540.21 ruu to unroot and remove any possible modifications, reflash twrp (but do not root), restore your /data backup, reflash the 7.17.1540.21 stock recovery and then try the ota update.
If its possible for you, I would really appreciate if you could share the ota update zip file so I can add the new files in the dev edition collection. To capture the ota zip file, download the ota update but select "install later". once downloaded go to your download folder and you should see a zip file starting with "OTA_M7_UL". Copy it to your computer and upload it (if you can).

u have a point about what u explained to me
i have been playing with android flashing and stuff from long and quite understand things and easy for me
and i didnt understood what happened when last time i got little update and then i had problem and phone went to bootloop
right now i might not be able to flash RUU because of my data in cell and work issues
if there is any solutions without flash let me knw and i cud easily upgrade from ota file
i will try upload and provide u link for it

Help a newbie; LG Optimus L90; learning to flash

Current situation: pretty much complete newbie. I broke my factory OS after rooting it, I think I deleted something Settings needs, so anytime it needs to access settings I get "Unfortunately, Settings has stopped." I factory reset it hoping that would help, but now after loading it gets stuck on a cycling white screen reporting that error (I think it's trying to set up the phone.) The error message prevents me from doing the touch-four-screen-corners trick I've read about and bypass set up. So, stuck on phone setup errors as near as I can tell.
I do have my user apps backed up with TiBu, but couldn't get the recovery zip from TiBu to work. I downloaded CWM but didn't figure it out yet. Also unfortunately I can't get the USB drivers to work (the LGE Android MTP Device won't install), so I think my only way of getting files to my phone now is using the microSD cards.
I'd love some help! I think my factory OS is FUBAR, so I'm not trying to fix that, instead I'd rather just get a cool ROM loaded so I can continue learning with a working device with said cool ROM. I don't fully understand terms that I know I need to like "bootloader" or what CWM / TWRP actually does or how to use them (I need to make a custom recovery ROM?). Or where to get a cool ROM or which to pick, some step by step basics on from some experienced users would be fantastic! Thank you so much!

So you were on stock, rooted, backed up and then messed the ROM? Flash stock ROM again using LG Flash tool (there is a thread in the main section), it should not wipe your data but you'll lose root. Hard to fix if you're not sure about the problem and have no easy access to files. Just make sure you flash the correct version for your model (D405, D410hn, etc), preferably the same version you have now so you won't need a factory reset after flashing...

Thank you, this put me in the right direction. I ended up discovering that even though the " LGE Android MTP Device won't install," the flashing process worked with this program via USB anyway. I'm going to lick my wounds a bit before trying to flash a custom ROM. Thank you!

For the rom installation, after unlocking your bootloader and rooting, download the app Flashify from Google Play, then install TWRP or CWM zip file as recovery image. Then, from there, you can install custom ROMs or make backups of your phone, etc. A cool custom ROM I recommend is CyanogenMod, it ports newer versions for older devices. So, you can have Android 6.0.1 in your phone
