Long time lurker. I read and can use Google . Regardless, it failed and scared the crap out of me as it wouldn't boot. Got back into boot loader, fired up EXE again and it seems to have finished the 2nd time. A few more grey hairs, but all is good my friend. Thanks.

Same thing happened to me! Failed the first time around, worked the second. Booting now and it appears to be working (Android is upgrading...)

So when I use the ruu for sdcard and I reboot after I get send to recovery and can't boot system. Why is that?

EXE/ZIP RUU M8_VZW 5.0.1 Help
I installed the RUU zip via SD last night. I was running Dottat's EXE/ZIP RUU M8_VZW 4.4.4 (s-off only) with stock recovery. When I flashed the 5.0.1 RUU zip, I have a couple Partition Fails (unfortunately, I don't remember exactly which ones). However, in the time since I installed it, I saw all the new messages in the thread about others having the same Partition Fail errors. Even with the errors, my phone booted fine. I am having some weirdness though (major lag after sending a message in Facebook Messenger app....a reboot resolves the lag for a little while, then it returns; Verizon Caller ID app won't load; logging in to Swiftkey keyboard's cloud with my Google account fails with an error). So I see the new zip to flash the L Hboot BEFORE flashing the RUU. Obviously too late for that. Also, I installed TWRP recovery in place of the stock recovery.
So my question is: How should I proceed with trying to get the 5.0.1 to flash with no errors? Should I install Dottat's 4.4.4 (s-off), which will get me back to stock recovery...then let it boot up. Then flash the L hboot, and then finally flash the 5.0.1 RUU? Or are there other alternatives?
Thanks!

Run it once more. The failed PU was for the data partition. If you run it once more it will be successful. I think the root cause here is the changes to partitions that occurred with this OTA and that the likely solution is to flash the L hboot first before doing the RUU to L. Once on L firmware/OS you can use the RUU again with no issues.
One big dang speed bump in all the fun.

Can I run the RUU again using TWRP? Or do I need to be on Stock Recovery? And thank you for your help!!

recovery doesnt' weigh in here. You can install it from bootloader using the SD card method.

How do I flash L Hboot? with twrp? do I have to flash it or can I just use the ruu to get to the new 5.0.1 firmware? thanks

So you asked to report our experience ...
First, let me say thanks. I am now on 5.0.1 and back to root thanks to your work and willingness to share.
Background:
I was stock 4.4.4, unlocked, s-off with TWRP recovery when the VZW 5.0.1 OTA hit. I had a number of bloatware apps frozen through Titanium Backup and probably due to a combination of all that I couldn't load the update. Reflashing boot, system and recovery still wouldn't let me take the OTA, so I ended up using HTC SyncManager repair to make Verizon happy. I got the update, kept unlocked and s-off, but lost root.​
Recovering Root:
After finding your stuff, I first tried loading through the bootloader with your zips in the root of my SD card (128 GB, single partition, exFAT). No go for either the hboot or the RUU. both gave me a "Wrong image" message and only allowed reboot to system.
So the next step was to try flashing with TWRP. I flashed TWRP 2.8.5.0 via fastboot and then let it do all it's stuff (Busybox, SuperSU, SD Card Fix, etc.) , rebooted to system just to have everything catch up to itself, and then rebooted to TWRP recovery. I then flashed the hboot and the RUU through TWRP, rebooted, and I'm back to full root.​
So again, thanks! A happy camper backing everything up with Titanium again and hoping that you really wanted to hear a real-world experience.

Well, XDA does call me a "Junior Member". Probably a good reason for that.
Looking back at the TWRP log, it seems you are right and my attempts to flash hboot and RUU from TWRP failed (but any indication of that flashed by so fast that I couldn't tell). So does that mean that my fastboot flash of TWRP recovery opened up everything that I needed to get root directly from TWRP (installation of BusyBox and SuperSU)?

Most recoveries will offer to flash su on an unrooted rom. You can either do that or manually flash the newest supersu.zip After you boot up you can install busybox from an app like this... https://play.google.com/store/apps/details?id=stericson.busybox
So what rom/firmware are you currently on?

After using the RUU, it finished with a successful update. I booted into recovery to create a backup, but now when I try to boot back into the OS, it goes back into TWRP like it would if I were booting into recovery. Anyone have any ideas?

Initially, yes. I flashed the latest TWRP. I think I might have flashed the wrong version. I'm rerunning the RUU. I really appreciate the help.
If it was the right version by chance, do you have any idea what could've caused that?

Did you use flashify? Reason I ask is that app still thinks it's a Sprint phone. Use the twrp I have posted in the op.

[HELP] HTC on e8sd MM update install ERROR

hey guys, yesterdy I got a notification for android 6.0 upgrade and it was a ~100mb file for preparation so i downloaded it and charged my battery and tapped to install it, it reboots and wants to start installing but then goes to recovery menu and gives an error
the phone is all stock, no root or bl unlock or anything
I attached the error msg below:
it's m8sd not e8sd, mistyped in topic

Might be due to bad zip file! Download the update again and try!

I had a similar error as yours doing exactly the same thing but mine was a e8sw running LP5 Sense6 rooted stock with xposed.
Even when I uninstalled xposed and disabled supersu, I still could not install the upgrade.
Finally managed to get the upgrade by going all the way back to stock and allow the OTA updates all the way up the MM6 update. Took me nearly 2 days to do that.
I have taken clean twrp backups of all the stock updates and will try and post them here soon.

thank you for the information, but as I mentioned in op my phone is already all stock, I havent ever moded or rooted or anything, it's stock locked bootloader

Have the exact same issue. My device is compelitely stock. Tried flashing the recovery from the downloaded OTA but still got the sama error. Hopefully someone will be able to resolve the issue.

if you have problems in installing OTA updates, follow these steps
1. check if your CID and MID are matching each other. they should be both for same region. mine are for vietnam. mec_dugl / HTC__057
2.Flash an stock RUU from http://forum.xda-developers.com/one-e8/help/htc-one-e8-mid-cid-ruu-ota-twrp-t2903210
3.Skip all registeration process and directly go to update menu.
4.this is a 3 stage update process: a small update for some applications/another 100 MB update for making device ready for main update!! / at last 1 GB main update . each one should be downloaded and installed separately.
5. after downloading 100MB update, DO NOT restart. coneect your phone to PC and go to download folder on phone internal memory, there should be a zip file containing updates(sadly I forgot file name), copy it on your PC and extract recovery.img from it.
6. boot your phone into bootloader and flash stock recovery you've extracted using fastboot.
7. now you have complete stock ROM. go to setting/update again and follow update process.
8.after updating you may flash twrp and supersu.
9. I don't know why, but there is a good chance that after messing with system files in MM you get stuck in several kinds of bootloops and soft-breaks. Don't worry; all you should do is going to recovery and wiping caches. sometimes you need a factory reset too. also have in mind that a complete boot after changing system files may take up to 15 minutes even without wipes.

@sam5154 well thank you for the info, Im gonna try these steps except, I will try to download again and flash recovery and try it before flashing a RUU and lose everything
but I hope it works anyway, btw mine is also vietnam region.

Hi, thanks for this. I will try this once i got home.
But i have one questions, mine is Vietnam MEC_DUGL with stock lollipop 5.0.2. The RUU only available for stock lollipop 5.0.1. Can I use this RUU or should I look for specific RUU for lollipop 5.02?
Thanks!

If you gonaa try that, then remeber to unroot and uninstall xposed, and you can use titanium backup for restoring your apps and data of course.

Here you go :
If you want more information, use ADB (if you don't how to get it going, use the search on the forum or Google about it).
While you phone is connected to your PC, type adb reboot bootloader and wait for your phone to reboot into bootloader mode. Once there, you can perform fastboot commands like getvar. Type fastboot getvar all and you will see all the information about the phone, including the product variable which lists the model you have.

btw I did go through the steps of downloading the 110mb update and flashing its recovery before pressing install and that didnt work and still gives OP error
so I guess I have to use RUU but not gonna do that for a while and also Im not so sure it'll work because the phone is already factory stock!

Yes bos, i also did the recovery trick but still cant make it work. So the only solution we havent try is to flash RUU which i doubt also will make it work since my phone also factory stock. So i guess will stay in 5.0.2 for a while.

Hi, I have managed to finally update my Vietnam HTC One E8 dual SIM (MEC_DUGL) to Android 6.0. The problem that cause the error is the error recovery file, hence I re-install the RUU to get the correct recovery.img file. Below are the steps :
Note : Try with your own risk
1. My device is currently stock 5.0.2 no root and locked. Before starting the update process please make sure to backup all of your important data. Im using the stock HTC backup software, when you restore your device after you finished your update process, it will re-install your currently installed apps , contacts, settings, etc.
2. Download RUU for your device here : http://forum.xda-developers.com/one-e8/help/htc-one-e8-mid-cid-ruu-ota-twrp-t2903210
I downloaded :
[Vietnam][DUAL][M8sd][mec_dugl][CID HTC__059][OPAJ20000] :
[Lollipop 5.0.1][2.35.425.2] : LINK
Seems not match with my current software (5.0.2), but eventually it will do the magic.
3. Flash RUU. NOTE : You will lose all of your data in your internal phone memory. Make sure to backup all of your important files.
Steps:
1) Download RUU.
2) Rename RUU to 0PAJIMG.zip (the first character is a zero, NOT A LETTER O)
3) Put renamed 0PAJIMG.zip on your external_SD
4) Boot into your bootloader and make sure your in hboot and let it update its RUU.
5) No PC, no adb, no fastboot, no terminal is needed, just a root explorer to rename and transfer the renamed RUU file to external_sd
6) After you have updated your RUU, make sure to remove the 0PAJIMG.zip from your external_sd because it will ask to update your RUU everytime your reboot to your bootloader which it is technically supposed to do but its unnecessary after you have done it once (unless you are planning on flashing RUU again).
7) Done!
Source : http://forum.xda-developers.com/one-e8/help/htc-one-e8-mid-cid-ruu-ota-twrp-t2903210
4. Reboot your phone, now your phone is back to factory stock, connect it to wifi, no need to set up any account, just go directly to software update from Settings > About > Software Updates. Just install all the available software updates (5.0.2 > 6.0 part 1 > 6.0 part 2).
5. BOOM! Your HTC One E8 now runs Android 6.0.1 Marshmallow.
6. Restore your phone from the stock HTC Backup Software.
7. Done

Please help: How to return htc u11 to stock

Hi guys,
My phone now is on LeeDroid custom ROM (Build 1.03.401.6.9_g CL923215)
What are the steps to return the htc u11 to stock please?
The original software number of my phone is: 1.11.400.4
EDIT: I went to: https://forum.xda-developers.com/showpost.php?p=72425224&postcount=5
& downloaded stock recovery & nandroid TWRP backup (for 1.11.400.4).
However, I couldnt flash that nandroid TWRP from TWRP recovery.
Long story short, I just got the phone today, I made a big mistake by not inserting the simcard in & testing to see if the phone working or not.
So, I went straight through the process of unlocking bootloader, installing TWRP, Rooting, Installing custom ROM without making a nandroid backup.
For all that, the phone did not recognize the sim cards (tried both my sim & my gf's sim. not working)
The store will take back the phone as long as I return it to stock.
Thanks for your help!!!

You'll need to download the stock rom for your verison (ruu). Hopefully one is available. Check the guide section here.

Restore the TWRP backup, check everything is working, then flash stock recovery if you need to. The stock Nandroid should include recovery asfaik. I'm more of a trial and error guy lol. Read guide pages to know for certain, check HTC 10 guides, same steps.

Get the one from here and follow instructions. That's what the thread is for. https://forum.xda-developers.com/u11/how-to/collection-htcu-u11-ruu-firmware-t3612048. Sorry i don't have time to do the leg work for you (i'm out atm), but it's all there.

download this Official RRU firmware and install it https://forum.xda-developers.com/u11/how-to/unlocked-htc-u11-software-update-6-19-t3624814

Use the ruu, you might need the HTC drivers but in the future never not make a backup, 15 mins could save u a major headache

Your going to need a full signed RUU zip matching your original firmware and CID buddy.
Based on your original build number its an Indian dual SIM device so here is the ruu:
https://www.androidfilehost.com/?fid=817550096634780026

On the PC side, what was the exact error message?
you can ignore the warning from the phone side.
I had a similar issue the other day, but then I was able to run the RUU upgrade to rest my phone back to stock as I had to ship it back for a refund, to get the new Red ones
When I ran the RUU thing it wouldn't detect the phone, did a few things, and then it was finally able to detect the phone.
and when it started updating the Boot image it hung for a long while, I had to restart the phone back into download mode, then run the RUU again, and it was able to continue from there.

Problem with reverting back to stock and take OTA!

Hi
I really need help to go stock on my device.
I unlocked my bootloader, flashed TWRP and Magisk on stock rom and installed the ViperU Magisk Module.
I also made a NANDROID of the stock ROM before, unfortunately there is no Recovery in it, since i had TWRP already installed.
Then an OTA (oktober 17 security patch) was available for my device and i startet the install process, but it didn't install.
TWRP open recovery would run not even 1 second then exit.
In order to get the OTA I restored stock recovery (which i had to extract from OTA, since i forgot to back it up) and started OTA.
--> Red Triangle!
Even after restoring stock NANDroid the OTA wouldn't install.
My mistake i think was that i didn't kept the stock system read only when i did the backup in twrp and swiped to allow modifications.
According to some threads here, even mounting the system r/w would break OTA functionality.
So since i also have no RUU for my device, i don't have the chance either to go back to stock. Maybe you did that mistake too.
The only way i can think of now, is to go temporary S-OFF, change CID and MID (to 401 international for example), flash Firmware and run the RUU for it.
But i'm not sure it'll still work after flashing the firmware.
Can anyone maybe confirm this way would work?
And is there an other way available?
Thanks!

Hi
Yes, unfortunately there's nothing available for my device.

Does the phone boot into os?

You cannot take an OTA with TWRP. You need an untouched system image to take the OTA. Easiest way is to RUU to your current firmware. Let the system update.

Actually that's not true, TWRP appareantly has a open recovery which works with OTA.
Also the RUU doesn't have to match your Firmware.
What i did was following:
-Had TWRP and a running ROM, rootet with magisk
-Downloded a RUU for my MID (picked the 401 one for international unlocked, i think you can take any)
-Installed sunshine and went temp s-off
-Went into download mode and changed cid to a matching one (HTC__034 -> Europe for me, there are other compatibles)
-Renamed the RUU (2PZCIMG.zip) and put it in the root of my SD-Card
-Inserted the SD-Card and rebootet to download (there's an option in download mode for that)
-pressed volume up to start installation
-Done, phone reboots with stock system, stock recovery and right firmware
Also I installed TWRP right back and magisk and tried to take the OTA. It installed without problems through TWRP.
Afaik, it will work, but replace TWRP in the end, so you will have to reflash twrp after every OTA, or you just take the recovery out of the
OTA and flash it through SD-Card (you have to rename it).
So that's the way to go if you have to go stock and there's nothing in the collection for your version.
Hope this helps.
Edit: Please remember to keep TWRP in read only! you will still be able to flash zips like magisk for example.

Hey,
after you had flashed the 004 Ruu, did you change S-off back to S-On?

since s-off is still temporary it will go back to s-on as soon as you boot into recovery or rom.
also, i flashed the 1.27.401.5 ruu, since i wanted to see if the update to 1.27.401.12 ota works with twrp and magisk installed.
it does, just remember to keep recovery read only!

What do you mean by "read only"? Is there a setting where I can do that?

If you take a bone stock phone (when you buy it for example, or after running a ruu), the first time you flash twrp and
boot into it, it will ask you if you want to keep the system in read only, in order not to break the OTA functionality.
But you won't be able to restore backups or install zip which changes system partition (Custom ROMs, xposed, etc.).
If you want to keep OTA functionality, you can keep it read only and still be able to flash zips like magisk and so on.
Once you swipe to allow modifications doe, there is no way back, so keep that in mind!
Mounting the system partition once in rw (read/write) will break OTA permanently.
If you ever decide that you want to modify the system partition anyway (going custom ROM) you can change the setting:
TWRP-->Mount-->"Mount system partition read only"-->uncheck it
Correct me if i'm wrong.

Ah ok, got it.
I would want to keep the OTA functionality, since I want to keep it stock with root privileges. That's all.
I won't try custom roms anytime soon. Thanks for the tip.
If I had known that before I flashed twrp I would have been able to update OTA now, right?

Yes, over the last few months AFH has been extremely slow.

Ok I will state it in another way. The easiest way to take the OTA is on an Untouched System and Recovery Image lol. You can with TWRP however the firmware will not flash. Hence probably your problem. You do know there is an RUU for 2.33.166.6 for your carrier. https://www.htcdev.com/devcenter/downloads

I have already seen that, but its like 400 mb big, if I remember correctly, hence not the entire files, right?

lol. That's the site i was searching for.
But since it's the source code, you would have to compile it first, right?
Anyway, are you sure? Cause from what i can see the firmware got updated too.
In fact, in this post under point 4. it states, that it's working.

The htcdev stuff is source only. No good. Also, once you flash twrp you can't take ota. You must be stock to take ota (s-off and bootloader remain untouched and do not matter for flashing, there is no need to s-on nor relock the bootloader ever).
To achieve stock just flash the same firmware you currently use as a zip from the external sdcard. The only things lost is root and twrp.

Yeah i guess you are right it is the source code. Even with TWRP stills seems like a lot of work to update. Ya'll need some custom ROMs installed. Flash signed firmware.zip, reflash TWRP and flash updated ROM. All done. If by chance you ever needed to return to stock, flash your system image backup. Ya'll make things so complicated when they really aren't. lol

Well, I managed to do it exactly the way you did.
Everything worked just fine. I changed the CID to HTC__034 and flashed the ruu file updated to Oreo and flashed TWRP kept it at read only and rooted the phone.

Save my bricked U12+ with the rom from another U12+?

So I've soft bricked my phone trying to downgrade android. I forgot to install TWRP and then flashed the ROM, only to discover I stupidly forgot to S OFF when I tried to flash an android 8 RUU. Because my phone is S ON I can't downgrade, and there is no stock android 9 RUU for me to flash back on. I was just going to send the phone to HTC for repairs when I had an idea, I have another HTC U12+ (same region some software as the original android 9). Can I not simply copy the ROM from this U12 and flash it onto my bricked U12? The working U12+ is on stock and is not rooted. I'd prefer not to root but am willing to if this will work. Can anyone let me know if this is possible or give any other advice? Btw if anyone has any other ideas on how to fix the bricked U12+ I'm open to suggestions. Thank you all.

Hi,
If your U12 is S-on, why not iron it S-Off? Or is it not booting? It is not possible at the moment to copy a complete rom Pie, a backup will not have the party 'vendor' so will not work! Without S-Off impossible to flash a TWRP recovery and anyway it is necessary the base vendor of the same version! Or it will have to wait until a complete RUU sort for Pie !!

to research for myself ( see my other thread about strange things on my u12+) did the same thing today, reverted from pie to oreo
note that my phone is european dual sim and cid 034
i only unlocked it but it's still s-on so it's possible to downgrade with s-on and locked/unlocked
just follow this procedure and be sure to use an oreo RUU compatible with your phone ( single/dual sim, same cid etc ) and rename the ruu only leaving the first 7 digit and letter
take your time to download the file because it's slow and don't rush because I know the feeling as in one step I tought to have lost my phone too!
https://forum.xda-developers.com/u12-plus/how-to/downgrade-s-t3930103
note: i needed to flash the ruu in download mode from sdcard two times because the first didn't work, when working it will say that is impossible to boot, will ask to reset data, do that and good to go wait a bit after logo
i can guarantee it worked from 2.55 to 1.30 firmware so it was a giant leap back!

I've got the exact same phone/cid as you. So im trying to follow that thread but i cant install twrp. I've downloaded the latest version and tried previous versions (note my software version as shown in download mode is 1.30.401.2) and all i get in the command prompt is:
PS C:\Users\User\Downloads\platform-tools_r29.0.2-windows\platform-tools> .\fastboot boot twrp-3.2.3-1-ime.img
Sending 'boot.img' (31196 KB) OKAY [ 1.940s]
Booting
and then its stuck on that screen, the phone just says:
flash image success (1/1)
Start downloading.
What am i doing wrong? Secondly ADB commands no longer work, im guessing because of the device being bricked (i've tested on my other htc and adb works fine on that). Fastboot commands still work fine though.

I downgraded on pie, do a getvar see what the build number & cid mid, I was on 2.47.709.1 my build was 1.53.709.7 , I found the right ruu(1.53.709.7), then decryped it, put system image & boot image in adb file. Renamed the ruu 2Q55IMG flashed it from Sdcard (32gb or less) it hangs on boot up, pressing on off it restarts & boots eventually, then I adb reboot download getvar again to make sure a partition is active. Then flash the boot image on b, then the system on b, if it hangs on system just wait, there's a delay it might initially fail but let it run through ,as it can't flash the wholes system at once, it breaks it up, takes a couple of mins, restart, it update fine, I've done it three times, never bricked an HTC b4 lol

Glad to hear that your issue is resolved. I should have just flashed a RUU before trying to boot TWRP, I just didn't realize that I likely overwrote the bootloader on the RUU mode flash. Oh well.
