[Q] How to extract original stock Rom?

How to extract stock Rom? The case is that I haven't done backup of my stock Rom branded by era provider.
Now some guy told me that he just bought desire z from era and his Rom is identical to RUU_Vision_HTC_WWE_1.72.405.2_R_Radio_12.28e.60.14 0f_26.04.02.17_M2_SF_release (available on this forum)
except radio code which is ending with fU instead f.
So if I would like to get Rom which is flashed on his device, to have exactly what was on mine on the beginning what and how it should be done?

Ok thanks it is for sure usefully guide but I'd like to know how to retrieve or backup stock Rom from the phone with original stock?
Sent from my HTC Vision using XDA Premium App

Ok, if I understand you right, you currently have a phone with stock ROM, and you want to take a backup of that phone, correct?
If that's the case, I think you'll still need to root the phone in order to install Clockwork recovery. Once you have Clockwork, then you can take a nandroid backup of your phone. So I don't think you can grab a backup of stock ROM before it was rooted.

Yeah so this a problem. During rooting it is necessary to downgrade your soft to 1.34 what automatically force you to loose your stock Rom. :/

Oh right, now I remember. I think if you can't find the exact RUU, you're out of luck. What do you want that backup for anyway?

No no I wanted only to have a possibility to back to the stock Rom if my phone will have to be sent to service on warranty.
I know one guy from Poland who also bought a phone from the same telcom operator - era.
He gave me info that the stock Rom on his phone is:
12.28e.60.140fU_26.04.02.17_M2
While on the forum can be find the same but with one difference in radio code - only f instead fU
12.28e.60.140f_26.04.02.17_M2 and can be found in this thread:
http://forum.xda-developers.com/showthread.php?t=879384
But what does it mean this difference mentioned above and if it is negligible or not?

Well, unless you've flashed a custom radio, another option could be to extract everything from that RUU you found in the forum and flashing everything except the radio.
Although if you want to send your phone for warranty you'll probably have to do a bit more work to get s-on again...

I've flashed two ROMs first one was CM7-R2 and then I've decided to use Virtuous 1.0.1. I don't know if during that process also radio was flashed :/ Was it? I am new Android so I don't know some things yet.

I'm quite sure that flashing those ROMs do not change your radio. So if you need to send for warranty, I think you'll just need to flash the ROM part of the RUU (should be able to find a post somewhere which tells you how to extract just certain parts of the RUU) and then reflash partition 7 to get S-OFF. If you used gfree, it would have made a backup of that partition before it gave you S-OFF. Hopefully you still have it.
Actually, have you taken a look at this?

[Q] NewB needs Help installing Rom =(

Ok.. so I'm absolutely new to this rooting and flashing roms and stuff. I want to install the SkyRaider 4.0 ROM. I believe the first step I need to do before I can install this ROM is to root my phone? Do I do this through Unrevoked or through ADB??? Like in this link? http://forum.xda-developers.com/showthread.php?t=709220 . I checked the WIKI for DInc and it doesn't mention anything about ADB.. So do I need to do that??
So lost. Thanks so much for your help guys

Use the unrevoked program, its so simple, literally one click. Once you have root you'll want to make a backup in recovery before you flash skyraider.

Thanks. So what's up with ADB? Will I need it at all? Do I need to follow the guide as in the link I posted above?

First root using the unrevoked program as mentioned above. Then post back for more help on the ROM flashing.

I wouldn't worry about adb right now. Don't need to use it for rom, kernel, radio flashing.
Sent from my ADR6300 using XDA App

Honestly, I've never even had to use ADB. Definitely not required. It's nice to have sometimes. But usually something like root explorer will suffice.
*should have refreshed first.
Sent from my ADR6300 using XDA App

Gotcha. So what's the diff between Unrevoked 3 and unrevoked forever? http://unrevoked.com/#inc

Unrevoked forever gives you permanent root. That is definitely the way to go, and the best way to get your ROM successfully flashed. ( And stay that way ).

Also let's you flash unsigned files in hboot, like radios and splash screens.

Just thought I'd add that you can also go back to stock S-ON later on if needed (warranty replacement, etc).

And in case he doesn't know what S-ON and S-OFF means, it refers to the state of the security "flag" on your device. With S-OFF, your warranty is void, however you can turn the security back on as well if you need to take it into verizon or something.. Using unrevoked forever, it will turn S-ON to S-OFF.

Can SkyRaider work with S-ON? aka without dealing with Unrevoked Forever at the moment?

No, I don't believe it will. Is there a reason not to do unrevoked forever? It take less than 5 minutes to complete

You should be able to. S-OFF is the way to go through, you can still revert S-ON later.
The whole "security" title it has is meaningless against actually security of your phone, with S-OFF you're more free to tweak your phone.

I see, but I hadn't done unrevoked forever (yet I still had root) and flashed over my first ROM... didn't have much luck. It ended up reverting to stock everything automatically, which was really strange. Haven't had any problems since S-OFF though.

Well, I did both unrevoked3 and forever in the end. Got it up and running with skyraider now =) thanks for all your help guys!

Huh, thats odd. I was rooted and S-ON when I first did my starter ROM: SkyRaider 2.something lol. Didn't encounter any problems except for wonky audio with flash, but that was an easy fix. That was back when stock Incs were rockin' Eclair lol... Sorry bout my off topic reminiscing :S
I'm glad you got everything running good OP! Enjoy the wonderful world of the rooted Incredible!

Yeah, S-OFF isn't required for ROM's. I flashed many ROM's before S-OFF was even out for the incredible. Back in the 2.1 days

[Q] Can't flash any rom. Stuck. M8 UK

Hi,
I am not new to rooting and flashing but I seem to have jammed.
I can flash custom recoveries(used both CWM and TWRP) no bother but I cannot flash rom.
I have tried pushing and side loading. TWRP just says failed.
CWM says cannot open update.zip from tmp (bad)
I am unlocked.
I am S-ON so I don't know a way around that atm without a ROM. I have tried reinstalling stock but failed.
HTC one M8 UK EE network.
Would love to fix this please.

I'm a novice, this is my first android phone but I believe you have to be s-off to flash ROMs. I'm on EE too, what I done was paid for Sunshine, about £14 I think, that unlocked the bootloader and s-off. I can flash ROMs no issues.

As I would, normally.

Toolkits cause more issues than they solve.
Try:
fastboot erase cache
Then flash recovery again, and see if that helps.
Also, do you get the phone model number as a response when you type both:
adb devices
fastboot devices

Not entirely sure how i fixed it but I'll list what I did.
Usually I work from a mac but decided to start afresh on my desktop.
I downloaded venom for m8
reflashed TWRP recovery.
Booted to recovery.
wiped cache and such.
Then adb side loaded the rom.
Some reason it worked. I have done this a good few times previously and with various rooms, not just venom.
I was using the AIO toolkit to side load this rather than the ADB cmd prompt.

Thanks for posting the steps that worked for you.
Like you said, hard to say what fixed it. Perhaps getting away from the toolkit, maybe just re-flashing recovery (even though you had done so previously) or wiping cache.
If moving a ROM to the device form the PC, I prefer adb push to adb sideload. Sideload seems to fail sometimes where push is fine. Push is some more steps (booting recovery and a few taps there to flash the ROM) but it seems more reliable. Although if it worked, it worked!

That is google now. You cannot change it on sense roms to my knowledge. GPE you can used xposed and gravity box to create new "ring" shortcuts.

Thanks, ive actually been looking into the GPE ROM but not sure if i would need S-Off to use it, (S-Off is still kinda confusing) ive tried to use firewater but got a whelp error saying my device wouldnt work, and from my understanding, SunShine is the only thing that can give me S-Off, i will be doing this as soon as i have the 25 bucks to spend lol, id rather have it and not need it rather than need it and not have it

You can flash gpe Rom. Just don't try ruu convert guide. Get soff while you can. You can do all sorts of stuff plus it lets you easily recover from most bricks.
Btw. Don't use toolkits. Learn adb and fastboot commands. They are easy and will make your life a lot easier.

No. Firewater and sunshine are tools for soff. Those are fine. Toolkits flash recoveries, unlock bootlader etc... It's good you did it the manual way. And yes HTC will patch soff method in next update. Ruu are restore files kinda like tar and Odin on your Samsung devices. You can only run one that is made for your device... Unless you have soff. You can truly convert your m8 into any m8 variant. No advantages over just flashing a Rom. But with soff you can upgrade and downgrade firmware and radios. You can remove tampered and red hboot text. You can manualy perform updates with no need to lock bootlader. It gives you full flexibility of the phone.
Once you have soff they can't ever take it away.

As long as your running a Rom no update will be applied. Backup stock before flashing anything! So many people don't do this for some reason. You can flash it if you want. Aosp is still a little buggy on the m8. I would recommend gpe over aosp for now but it's up to you. There are some good sense roms too. I wouldn't flash any aosp without soff. Just in case. I've had aosp soft brick when I try to flash another Rom after it before.

WWE = world wide English
Changing hboot is often not needed just to flash ROMs. However Android 4.4.3 (HTC software 2.22) based ROMs (ARHD 10.2 is one) happens to be an excepton; as you will need to flash what is known around here as the "firmware package" which includes hboot, radio, and other things. If you don't flash the firmware, you will likely get some serious bugs on 2.22 ROMs, including long boot times, as well as broken WiFi and Bluetooth.
You can find the process for flashing firmware below. I used this one:
http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-t2837365
And specifically in the ARHD thread here also (note that for the AT&T version, firmware 2.22.1540 is recommended as you might get NO SERVICE on the international firmware): http://forum.xda-developers.com/showpost.php?p=54408500&postcount=9592
Be very careful you understand the process, as flashing hboot or radio is one of the few ways to actually brick the phone.

Just flashing a ROM is actually not that risky (although flashing hboot or radio can be, as mentioned). Its actually pretty hard to brick this phone just flashing a ROM, as long as you make sure to only flash ROMs or other mods only meant for the M8 (GSM).
Just be sure not to flash anything meant for other devices (including the Verizon or Spring M8) as you can actually brick the phone this way if the partitioning is different, and you overwrite any critical partitions such as hboot, radio, or the partition table.
If you stick to the correct ROMs, usually the worst that can happen is a boot loop or failure to boot into the OS (phone stuck at boot screen). But if that happens, its usually not that hard to recover. There can be various reasons and different corresponding solutions. But usually reverting to nandroid, flashing a different ROM, or re-installing recovery (and flashing the ROM again) will fix you up.
Although, nervous is a good thing to be; as it will also mean you will be careful. Which is really half the battle.

Ok guys i have gained S-Off on my device, just a quick rundown, and correct me where needed
1. S-Off is not required for rom changing, but helps
2. I have 4.4.2, any rom that has a different version than this you must first flash the firmware package first, and this can only be done in fastbootusb (if step is skipped can expect lots of errors or bootloops)
3. WWE just means roms from america? (Doesnt seem correct)
4. Changing HBOOT is not required for changing roms, unless the rom calls for it
5. Other than the android version, there is a htc version on the phone as well?
This is kind of overwhelming so far, and im not the best at instruction manuals, im more of a visual learner. And it helps when things are explained in detail, for example, explaining that i need a firmware package helps, but why do i need it, the more i understand the better i can make my decisions. And thanks guys, this is huge help, ive always come to xda for help, this free community works better and quicker than anything ive tried

Downloaded the unmodified 2.22.1540.3.zip firmware, this is the correct firmware for my AT&T M8 right?
And if im right ill:
1. adb and flash the firmware twice to be safe, then reboot the phone
2. adb flash TWRP recovery, then reflash supersu in TWRP to regain root access
3. Then flash the ARHD 10.1 ROM?

Stock or near stock ROM

Long story short, I am rooted and s-on and running an older version of insertcoin rom. The TWRP backup of my stock rom won't restore and I want to use sunshine to s-off but it says I need to have a stock or close to stock rom. Can anyone recommend a rom that will work for me? Keep in mind that I'm still on firmware that is compatible with 4.4.3. I'm only needing the rom to enable me to s-off, then I can upgrade everything.
Thanks.

You could try looking here for a backup of your actual stock ROM.

Thanks, I've looked there before and there's only a nandroid backup. I've got TWRP so I'd have to install philz recovery to use that. I was hoping to avoid having to do that.

You do realize how quickly and easily you can switch back and forth between recoveries if you need to, right? Flash the backup, then switch immediately back to TWRP, then make your own with that recovery to save for later. Or you could just switch back and forth again because it is so easy. I'm surprised that there are no TWRP backups for you. Most have TWRP ones available.

If it just for SunShine S-Off purpose, just grab any TWRP 2.xx backup... you don't really need your device version stock ROM.
2.22.401.5 is a good choice.

MaximusHD is also known to work with Sunshine

thanks for the replies
OK here's whats happened. I downloaded the nandroid for my carrier and managed to install it. Its version 4.4.2 and it detected there was an update. I downloaded it and it installed fine, rebooted and it detected another update, then the wifi suddenly turned itself off and would not turn back on so I couldn't download the second bigger update.
I've re-installed the Insertcoin backup and it's all working again.
any ideas?

you shouldnt be taking OTA updates in the first place if you want to Sunshine S-OFF.... the more updates you take the less chances of sunshine working
