[Q] Can't update hboot from 0.43

Hi guys
I want to update my hboot in order to install Jb roms. My current rom is a costum one.
My hboot is: 0.43
my build number ( I got this in menu>settings>about) : 2.17.401.2
And in fast boot when I run ''fastboot getvar version-main" I get this: 1.26.206.2
I have downloaded this RUU: RUU_ENDEAVOR_U_JB_45_S_HTC_Europe_3.14.401.27_Radio_5.1204.162.29_release_298897_signed
I do this things:
Install a stock recovery
relock phone
Run RUU and extract rom.zip from temp but I can't extract it completely and I get the corrupted error ( In order to get recovery, boot.img and system files)
I continue the installing RUU process and i get [132] error, "update signature failed"
I don't know what eles should I do
Can anyone help please?

that is because thats the wrong RUU for your phone you need the O2 2.17.206.xx RUU first then you should be able to install jelly bean from there. i hope this helps

Download this RUU
http://www.htcruu.com/securekey.php..._Radio_1.1204.90.13_release_251230_signed.exe
Now put the phone in the bootloader / fastboot usb mode and lock your bootloader ( if it is not locked)
Fastboot oem lock
After this you keep the phone in the bootloader / fastboot usb mode and right click the RUU.EXE file on the pc and select
RUN WITH ADMINISTRATOR RIGHTS (or the similar command )
Reboot the phone and start updating by checking for updates in settings - software

[Q] Need the right RUU for my device! Please help!

Hi Dudes,
as I'm about to sell my HTC Wildfire S for a few bux. In order for that, I want(/need) to go back to stock firmware, but I can't seem to find the fitting RUU for my device.
I'd take the rom.zip out of this RUU, rename it to PG76IMG.zip and then I'd flash it throught HBOOT.
I already tried two RUUs:
1)RUU_Marvel_S_HTC_Europe_2.13.401.3_Radio_47.23c.35.3037_7.54.39.28M_release_236989_signed.exe
..as it had the right ending of the Radio version respectively the one shown when I boot into bootloader (7.54.39.28M)
...Error: Main Version is older! Update Fail!
2) RUU_Marvel_S_HTC_Europe_2.26.401.3_Radio_47.23e.35.3038H_7.57.39.10M_release_261695_signed.exe
...as it is the latest one available for the Wildfire S Europe
...Error: Main Version is older! Update Fail!
So, please help me!
Thank you all in advance!

Just download the 2.26 RUU by myself from here and extracted the radio, boot, recovery, system, userdata and ramdisk (-.img) from the rom.zip. Will flash them later and report back if it worked...hopefully it will
EDIT: After every single flash attempt, the terminal gave me sth like this:
fastboot flash boot boot.img
sending 'boot' (2870 KB)...
OKAY [ 1.279s]
writing 'boot'...
(bootloader) signature checking...
FAILED (remote: signature verify fail)
finished. total time: 1.910s
Sidenote: Only the bold written part - the "error part" - is important in that case as the rest depends on what I've chosen to flash (i.e. replace 'boot' with 'recovery', 'system')
Any help?!
P.S.: When I boot it boots still into CM (the ROM I come from).

U try format boot and other partition on CWM?
I dont have any problem with this files flashed on first time
Try format all, and again flash (first recovery.img)
Try lock bootloader, and unlock again.Check if u have installed usb drivers on PC.
Or try flash this files with CWM(install zip from SD card).
Or try this method http://forum.xda-developers.com/showthread.php?t=651526

If you have a stock backup, I have a stock recovery that should work for the LRA models, PM me. Since you're S-off you might take it to Bluegrass and ask them to flash it back to stock and start over again. S-off should stay after they've flashed.
I WOULD NOT use a Verizon or other LRA carrier RUU, since the radios and radio configurations are similar, but different enough that they will likely screw up your service.

hi,
can you help me with this i've messed up with my phone, didnt know its verizon, was assuming its GSM, but was unable to flash any custom rom except SkyDragon, so i thought its a firmware issue, got s-off and updated the firmware which caused radio to stop working, then figured out its verizon, flashed firmware from verizon as well but no luck, now i am not even able to flash any ROM, only AOSP or Verizon or SkyDragon intl boots the phone but then start rebooting every few minutes, radio not working so no calls no data, i am really stuck, there is not much help about this model, if there is a way to go back to stock i would like to go with that, any help would be appreciated.

I believe you installed wrong firmware which is a modded GPE firmware. That's why you can't install most of the ROM now.
You need to put correct CID/MID or at least change the CID to SuperCID 11111111 and MID 0P6B20000
It's not easy to fix your device now as you already installed some other region rcdata.img that come with the wrong firmware.
Anyway .. try again the correct Verizon firmware after change of CID/MID
You'll be able to install any Verizon based ROM but your data connection may still have problem.
Or better to install Verizon 4.4.4 firmware then restore LRA US 3.31.512.2 nandroid backup then do OTA if there is one. Restore the backup I believe you'll get wifi working .. after OTA .. your data connection should be restored.

sorry about that MID and CID actually was planning to go GPE so changed them but then read the forum and couldn't find a single success story of wlv going GPE so changed my mind.
CID is now super and MID is my original as you mentioned 0P6B20000
the problem is that i am unable to find the correct firmware for my phone. i spent 48 hours searching for it but no luck.
and dont have nandroid as well.
btw couldn't understand the code you have sent.
can you please help me with finding the correct firmware and nandroid or whatever is needed to get this phone working regardless of the version. have no problem going to the older version as well.
Thanks

Didn't realize you were GSM since you are trying to flash verizon firmware with a phone that has the same MID and product version.
If your phone is GSM, you could try flashing WWE/International firmware (4.16.401.10). That's what I am using on a Telus phone. MID for WWE is 0P6B10000, Telus is 0P6B16000. It works great.
I didn't change the MID, just switched to superCID and flashed the firmware. Your product version may not let it install, but it might and it won't brick you. You'll just get errors if it won't work. My product version was M8_UL_CAN and it changed to M8_UL after flashing the WWE firmware, so it might be worth giving a shot.

1. Install the 4.4.4 firmware that you can find here : http://forum.xda-developers.com/showpost.php?p=52017763&postcount=2
2. Restore the LRA_001 nandroid backup that you can find here : http://forum.xda-developers.com/showpost.php?p=58438595&postcount=14
Note : this nandroid is made with CWM and CMW recovery is included in the zip.
3. After restore, boot and check for OTA. You may not have data connection but you should have wifi connection.
4. After the OTA installation, you should get your data connection back.
Good Luck

Ok so here is the update,
After about a 100 reboots the OTA was successfully downloaded. But it won't let it flash, whenever I tried to flash it just rebooted, since the firmware didn't contain boot and recovery and I was on CWM I thought its recovery issue so flashed stok firmware and boot. It still didn't work, then flashed TWRP and tried to install OTA again, got some fingerprint error, please see the attached image.

When you restored the nandroid, do you restore the stock recovery included in the zip ?
OTA will install on stock recovery not CWM & not TWRP and not even on vzn stock recovery.
Do you still have the OTA.zip in internal storage/download folder ?
Copy that to PC, open it with 7-zip and extract out firmware.zip. Open firmware.zip and extract out the recovery.img
Flash this recovery.img. As your device is S-Off you can manually install OTA with stock recovery installed. Do you know how ? If not sure, ask .. will tell you how-to when I get to my PC. Not easy to write all these on mobile.
Or you can flash this extracted firmware.zip in ruu mode, you'll solve your data connection problem.
Then you can redo OTA installation process.

when i restored the nandroid it didn't restore the stock recovery, i flashed the stock recovery from the firmware.zip, the OTA is still in download folder, whenever i check for update it finds the existing file verifies it and prompt to install it, i did select to install it, its still just rebooting, after a couple of attempts it once booted into recovery but then without any progress it kept rebooting into recovery, after several reboots it booted again normally.
so now i have the stock recovery installed, should i rename the firmware.zip to 0P6B2000.zip and install it via hboot?

You flashed the stock recovery from which firmware.zip ? The one from VZN won't work. The one from the OTA zip will.
No .. that's wrong to rename firmware.zip to 0P6B2000.zip
Try this first :
firmware.zip is the one from OTA zip, not VZN
Put your device on bootloader/fastboot mode and connect to PC (you should see fastboot usb highlighted in red).
Put the firmware.zip in your fastboot folder. Open a command prompt from that folder.
type below command :
fastboot reboot-bootloader (to make sure you're on fastboot mode)
fastboot oem rebootRUU (to put the device in RUU mode)
fastboot flash zip firmware.zip (flashing the firmware.zip)
You'll see : FAILED (remote: 90 hboot pre-update! please flush image again immediately)
repeat fastboot flash zip firmware.zip (to complete firmware installation)
fastboot reboot-bootloader
Check your bootloader now written OS - 4.21.512.4
Now reboot (your data connection should work now) and redo OTA process
EDIT : can you upload that OTA zip to your GDrive or Dropbox and PM me the link. That will help many people.

ok i did flash the firmware in RUU mode, i can see the latest version in bootloader mode, then rebooted the phone but now its stuck in bootloop,.
managed to get to bootloader again by holding volum and power button while it was rebooting.
cant get to home screen.
yes i will upload the OTA and share the link.

Install CWM and restore the backup again ..
After you already boot and run setup ... copy the OTA zip to root of your internal storage, not in any folder.
boot to bootloader and install the stock recovery from that LRA firmware.zip
select hboot then recovery .. you'll get black screen or red triangle .. press & hold volume up button and press power once .. this will get you to stock recovery menu
select install from phone storage
select the OTA zip
install
reboot

ok installed CWM, restored the nandroid, still rebooting and not signals.
flashed the stock recovery (the one from OTA) tried to install the OTA again, same problem rebooting again n again, managed to get into recovery once, but then stuck in boot loop on recovery, managed to get into bootloader by the volume and power button.

There's nothing much that I can offer to help. Your rebooting problem I believe due to motherboard cannot take the heat. I want to say this earlier but let you try all the possibilities first, you may have damaged motherboard that is why previously you have restarting problem when using your device.
Let your phone to cool down ... then try again. If still the same, need to send it to repair centre.

if i try to flash recovery i get this error:
remove signature failed

It seems the last OTA hasn't been kind to many phones. But, here are a few pointers:
1. Your cidnum: HTC__E11 is covered by the European firmware. Any x.xx.401.x RUU (such as 6.12.401.4) will set you straight.
2. You cannot flash a recovery if your bootloader is re/locked. Unlock first to proceed with flashing a custom recovery.
3. Your "device status: modified" indicates that you tried to flash a piece of custom software that modified your system partition, such as rooting via SuperSU when prompted by pre-3.0 twrp. This cannot be undone by hardresetting. You will need to either flash an uninstaller, or reflashing a stock system partition (or restoring a twrp backup of your current system partition).
The silver bullet solution is to flash a compatible stock marshmallow RUU:
6.12.401.4
I hope all this helps,
Cheers

hello, if i try to install compatible stock marshmallow RUU: 6.12.401.4 zip by adb with unlock bootloader i get error "signature failed", if i lock the bootloader i get "not allowed"..

That RUU zip file should be flashed from SD card NOT ADB. Simply, rename it to 0P6BIMG.zip, copy it to the root of your SD card, then boot into bootloader and follow the on-screen instructions.
Note on 0P6BIMG.zip : (first character is zero, and careful you don't rename it to 0P6BIMG.zip.zip)
Good luck

M8 bricked, cant flash new rom neither restore backup

Hey guys,
Recently I have bought used m8 with custom rom. Seller said he sells it because after trying to do factory reset (thinking it could restore to stock) he lost any gsm signal, only wifi worked. I had some experience with flashing sony mobiles and lg few years ago, so thought it would be easy to install stock rom and use device again. Googled a bit about flashing HTC devices, then downloaded rom, after that had some dificulties with win 8 and htc drivers, so tried to put rom into sd, it was too small. Somehow managed to put rom into device, tried to flash, had some errors, tried another roms, got another fails, changed my cid and mid, played with locked/relocked things, that didn't help either. Tried to restore a nandroid backup, even if it says restore was successful, after i choose reboot, it only boots me in bootloader. Now i cant access twrp, my pc recognises phone, but none of adb commands work.
I apologise if anyone got similar problem, but tried to look for explainations on my own, and found nothing, so this is my last hope to get it working.
Any help or info will be appreciated, I also am very interested in what you guys are doing, so i could even donate for people who can help alot.

A big mistake has been made, either by you, or the previous owner. As you indicated the previous owner lost GSM signal, I would guess that person may be the culprit.
Here's what I mean: Your M8 version is Verizon, indicated by the product name M8_WLV. I can see from the OS number (6.12.401.4) that installation of Euro firmware was attempted.
The Verizon version is somewhat unique, in that its designed for use on US Verizon carrier's CDMA network (in addition to GSM, HSPA, LTE) and therefore has its own partition layout, radio firmware, etc. Trying to flash any other version's firmware to this device will not work, and may result in a permanent radio brick. Essentially, only Verizon firmware or RUUs should only be installed to this device. Unlike most other M8 versions, you cannot convert the Verizon M8 to another version by changing the CID/MID (after s-off) and flashing another version RUU.
Indeed, the OS number in parenthesis indicates a problem with the firmware. And I'll venture to guess that this line is also in red font (which also indicated a firmware problem).
Your best (and really, only) option is to try the proper Verizon RUU. A lot of times, this will fix the firmware, and get the radio to work. Although there is a possibility that its a permanent radio brick (as we've seen a number of times). Try the 6.21.605.3 RUU from here: https://forum.xda-developers.com/verizon-htc-one-m8/general/official-ruu1-55-605-2-t2883845
Another couple mistakes that I can see:
There was never a need to relock the bootloader for what you are doing, since the device is s-off. Its not needed to do this in order to flash firmware or RUU (the main reason to relock bootloader) as this requirement is bypassed by s-off. A relocked bootloader won't interfere with the RUU I recommended. But it would hamper trying to install TWRP custom recovery.
adb won't work unless you are booted to Android OS, or in TWRP. Since neither of those are working, it is normal and expected that adb command won't work. Fastboot command should work, while booting into bootloader-fastboot mode (and only that mode). While fastboot is related to adb, there are important conditions and differences.

If the latest RUU doesn't fix the radio signal, I suggest to install the lowest version 1.5x. as the lower version usually will fix the NV partition which related to radio and unbrick it. (This is what I read in VZW thread before)

Good to know, I wasn't aware.
I think the 1.5x files would be here: https://forum.xda-developers.com/verizon-htc-one-m8/development/ruu-m8vzw-4-4-3-s-off-onlynewest-t2873144

Edited my earlier post.
Your earlier link is good ... click 4.4.4 RUU zip link, it's 3.28.605.4 RUU
The only way to reset the partition to out of the box stock is to flash your carrier's 4.4.4 firmware and the stock recovery for you device. Reboot to recovery and select factory data reset and let it do it's thing. If you watch the reset log you will see it mention resetting the NV partition.​

guys, thank you for help, downloaded latest .zip file, renamed it to 0P6GIMG.zip, did fastboot flash zip 0P6GIMG.zip and it shows this: target reported max download size of 1826
Invalid sparse file format at header magi

That's correct, you will need to change back to the Verizon CID and MID to run the RUUs, firmware. Sorry, I missed that in the details you provided.
Alternately, if you change to SuperCID (11111111) in most cases this will bypass the MID check (and save you some steps).

now got RUU mode with exclamation marks on the edges of screen..
changed cid to vzw__001, but now need to get to fastboot again, to change it to supercid and will try 6,0 ruu.exe 4,4,4ruu.exe and 6,0 .zip files i have downloaded
Edit: cid changed to supercid, still stuck on silver htc logo with 4triangles on the edges. cant find a solution...

Read this on how-to : https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
but use your ruu.zip not the one in the guide.
At the end of the guide, you'll see there are 3 methods to install ruu.zip

tried your method and got this:
C:\Users\Vartotojas\Desktop\android-sdk-windows\platform-tools>htc_fastboot flas
h zip rom.zip
sending 'zip'... (46028 KB) OKAY
writing 'zip'... FAILproject does not have sa key to decrypt rom
FAILED (remote: project does not have sa key to decrypt rom)
Execution time is 2(s)
already tried to do it with ARUwizard.exe and stuck on silver HTC letters with 4 triangles nad exclamation marks on the edges of the screen, cant boot to bootloader, and i dont have enough storage in SD card to put rom in it
edit: trying again with another .zip file, now got this:
C:\Users\Vartotojas\Desktop\android-sdk-windows\platform-tools>htc_fastboot flas
h zip 1.zip
sending 'zip'... (1760932 KB) OKAY

another question, what should be there in that ruu.zip? downloaded few and there is one with rom.zip, adb.exe, ARUwizard.exe, alot of .dat files and bitmap images inside, others are only with boot-signed.img and android-info.txt

What are those you downloaded ? Which link ?
In my earlier post, I specifically suggested this one : https://www.androidfilehost.com/?fid=95784891001604006
If in ruu.zip you downloaded has all those files, it means you need to extract the ruu.zip then run the ARUwizard.exe to install.

yes i have downloaded exactly this and two more, now extracted this, ran wizard and got error 171 usb connection error, tried another usb cable, another usb slot but same error, what could solve this?

Do you have latest HTC USB drivers installed ? As explained in this guide - https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
where it says - first you need this ?
Also try with USB2.0, if running it with ARUwizard.exe (that also explained in the same guide in the link at the lower part).
Or take only the rom.zip then
htc_fastboot flash zip rom.zip

I downloaded the 3.28.605.4 ruu.zip to see what's going on here .. it's a signed RUU, you're not supposed to extract it. No normal zip archiver can extract it properly.
Rename the whole as ruu.zip or rom.zip then htc_fastboot it after you put the device in RUU mode
fastboot oem reboot RUU
fastboot flash zip ruu.zip (or rom.zip if you renamed it rom.zip)
fastboot reboot-bootloader
also make sure your windows extension is not hidden so it won't actually become ruu.zip.zip where you will have unable to load ruu.zip error
The whole
0P6BIMG_M8_WL_K444_SENSE60_VZW_MR_VERIZON_WWE_3.28.605.4_HSM_Radio_1.09.20.0926_NV_VZW_2.11_002_release_393779_signed_1.zip
is the rom.zip
