How 2handle HTC s/wupdate install & twrp

[oldwolf613]

I just checked my Magisk 13.3-rooted Sprint htc u11, running 1.13.651.6 for htc s/w updates & d/l'ed the update abt 750Mb, which is said contained a security update & it was supposed to bring me to 1.28.651.3.

After d/l & clicking on install, it went thru 20% on the "gas gauge" progress bar, before the screen went black & 5 second
screen came up as usual & then the twrp main screen came up.

Not knowing what to do, I decided playing it safe was best, I simply rebooted the system & all went fine. I got a msg telling me that I have a system update & I chose to put installation off & chose to be reminded in 4hrs. In 4hrs, the fone will be off. I'm going to be AFK fm the fone - as I have to be away & the fone has to be of until Sat. nite when I'm done w/the other stuff I'm doing until then.

I'm not sure what to do, or why it rebooted, showed the 5 second screen & then went into the twrp main screen. I did nothing to make that happen. In the past I obviously unlocked the BL, installed twrp, & rooted w/Magisk 13.3 & Magisk Mgr. 5.11- carefully following posted instructions, but I have no idea why reboot went fm 5 second screen to main twrp screen & equally no idea if that should have happened- or what in hindsight I should have done.

***BTW, I have an icon in my notification bar fm the Updater program that is telling me I have a System Update Ready & I should tap on the notice to install.***

PLEASE ADVISE!

Is there any problem taking the 1.13.651.6 -> 1.28.651.3 update w/unlocked BootLoader & twrp & root that will damage my fone, the setup, or Bootloader, twrp, or root?

What should I do when I power-on & restart fone on Sat. nite when I will ostensibly get the update process kicking in after the 5 Second screen & then progressing to 20% of the update & then the Update process reboots & reboots me back to 5 second screen & then the twrp main screen (or maybe another prompt)? Or can I do something to prevent / remove the update if there are any problems.

Would going into a diff mode fm 5 second screen, like bootloader, download, or recovery mode & then have to do something else to get the System Update to work?, or do I have to do something else - related to unrooting, &/or removing twrp, &/or re-locking the bootloader ? - (please don't let it be any of that!), & how would I do whatever I have to do?. Or do I have to somehow avoid the update - don't know how to do that either- I've played w/this kind of stuff on a # of prev devices, but not on an htc device & I'm sorta like a newbie w/htc 'under the hood' stuff. ***Thanks very much in advance***. This is the only Sprint device I have… so I can't just switch to another fone & do whatever I have to do on this fone w/out any stress & plenty of time to sort out the details.

Again, TIA, oldwolf

You cannot update the phone while rooted. You need to be on an Untouched System image. There is quite a few threads explaining this. Did you do a twrp System image and boot.img backup? If not, there are a few different ways to update. You can flash(a few different ways to flash the signed firmware update in BadBoys ROM/Firmware thread. RUU(wipes everything) and then take the OTA. Flash the OTA in TWRP, however you will still have to manually flash firmware.zip inside the OTA. You could have saved yourself the trouble of writing this page long explanation and read through a few threads, lol.
Since you are on Sprint, there is BadBoyz ROM/Firmware thread HERE. 5m4r7ph0n36uru's firmware HERE

Schmeggy929, thanks so much!
If I knew why I got that result I would've searched threads for an answer. I turned on my U11 tonite & told it to cancel update. It told me install would be removed. Whew! Was afraid I keep getting prompted to do update, or worse, I'd not be given the chance to remove!

So far, I've only unlocked BL (htc provided step by step), rooted, & installed twrp (courtesy of Capt Throwback's guide) so that's the extent of my htc dev experience / knowledge.

You mentioned flashing OTA in twrp. Did a quick search & scanned thru replies, got basic idea; but need to ask, will that wipe my 3d party apps & data & settings? I'm guessing not... also, in which mode would I flash? Recovery, Download, Bootloader? Also, you asked if I did a twrp system image & boot.img backup & if not you listed those approaches. What should I do if Ihad done twrp backup? Usually I b/u everÿhing but the cache & will be doing that soon, along w/my homework i.e. looking up threads…

I'll do w/out the update until I'm better prepared.

I've been considering going to BadBoyz ROM, but would be curious to see what main screens look like & I see you are a recognized themer & on Team BadBoyz; would itbe possible to please send me some screen captures of the rom via PM; looked in ROM thread but didn't find any…

TIA, Oldwolf

Taking OTA, whether normal or flashing will not wipe apps. From what I gather you can (if you are stock and untouched System Image) can download OTA, Extract Firmware.zip , then back to OTA install, let it install(will reboot to TWRP and install) then reboot to Download Mode and fastboot flash Firmware zip.

If you did make a System, Recovery and Boot Image backup(even better) Boot to TWRP and restore those backups, reboot and take the OTA normal(as you would with a completely stock phone).

Or easier, download the updated signed firmware from BadBoyz Thread HERE. Flash with either scard method or computer fastboot method. Then download The latest ROM for 1.28.651.3.
None of these will wipe you apps and Data. Badboyz ROM is nothing more than a Stock ROM with great Tweaks. Other than my Boot animation , the two BadBoyz apps and some bloatware missing, you would never know the difference, except for performance and extra goodies.

 

[OMJ]

this is the easiest way I've found to install a ota...preparation

-from 100% stock, unlock bootloader, flash twrp

-on 1st twrp boot, keep ready only & immediately do a system & boot img backup

-once backup is done, copy stock recovery into the twrp/backup stock imgs folder & rename it recovery.emmc.win

-flash rom, magisk, supersu, whatever changes u want

-when a ota is available, boot to twrp, & restore your system/boot/recovery imgs backup

-boot to OS, download & install ota

repeat steps from top

@ Schmeggy929 is this the latest updated signed firmware ? : ->
2PZCIMG_1.28.651.3_RUU.zip ? & is the scard method renaming that file on root of sd card to 2PZCIMG.ZIP & flashing it fm twrp in download mode? If so the next step, as you said, would be to d/l the ROM - would that be
{ Bad_Boyz_Sprint_HTC_U11_v2.0.zip } ? & then just flash that fm download mode in twrp?

@ OMJ, After unlocking BL, & flashing twrp, & rooting (or does it have to be unlock & then root & then flash twrp,I forget) I had some 3d party apps & I made a nand backup of everything but cache fm twrp, to have a clean, stock, relatively new setup. I noted in Solid Explorer that under twrp/backups/sdcard_hexname/twrp_bu_name directory, there is a recovery.emmc.win file - is that the 'stock recovery' you were referring to? & wouldn't I just restore that whole backup to take an ota? - after unrooting of course! Also, aren't there stock image files to either recover from or take OTA? Have I missed anything? TIA…

Thanks much to all, Oldwolf

2PZCIMG_1.28.651.3_RUU.zip is a full RUU which will wipe your phone (except ext sd card) & restore factory imgs

this is the latest signed firmware, you can rename to 2PZCIMG.ZIP, copy to ext sd card & boot into download mode to flash...firmware is not flashed from twrp... 2PZCIMG_Sprint_1.28.651.3_signed_firmware.zip

signed firmware will overwrite twrp, so you'll need to reflash twrp after the signed firmware. my latest ROM is Bad_Boyz_Sprint_HTC_U11_v2.0.zip (based on 1.28.651.3), it's always flashed from twrp

unlocking bootloader is a 1 time thing, you've already unlocked so no need to worry about it. when u backup in twrp, you would need to make sure you chose the system img option to be able to restore for an ota, and you would only need to backup system & boot, if u chose recovery, it's not backing up stock recovery, it's backing up twrp.

if you flash my rom, there's really no need to worry about all this, I typically have a updated ROM ready for everyone the same day or within 24-48hrs of a ota. in this case, you would just need to flash the updated firmware, then flash my new/updated ROM.

for now, I would just flash the latest signed firmware, then flash twrp, boot to twrp & flash my ROM....no need to flash root prior to the ROM. if you do want to restore stock system/boot/recovery imgs for the next ota, I'll upload my backup...

 

[oldwolf613]

OMJ, I was going to leave my fone on pure stock, but since BB is mostly stock, & there are improvements & less bloat & you quickly update for new OTA's & put up prev stock img's in case OTA is needed, & you have been *so* responsive, I'm going to go w/your rom.

I have some stuff I want to research myself & then I'll go to BB.

I do have some Q's that I'd like to ask you now: You said that flashing the latest FW would kill twrp, if I put the Official TWRP App on my U11, can I use that to reflash twrp?, it has a "Flash TWRP" button, but I don't know if that process will work in this situation.

Also, will flashing the FW & thereby killing twrp do anything to "under the hood" stuff like pointers/links to NAND backups I already did since I added twrp? I have original setup + some critically needed apps I loaded until the 10day return period ended in 1 NAND (didn't want to unlock BL & root until I was sure I had no h/w probs, like some had w/audio adapter) a 'base NAND backup' & I keep one other, 'latest' backup of everything except Cache to ensure I have a NAND image to restore in case of emergency.
I'd hate to lose access to those if flashing FW & killing twrp would also kill needed pointers/links to those backups.

Since you said flashing FW can't be done from twrp, pls confirm that going into Download mode is done by pressing Vol. Up, Power, & Home/fingerprint buttons. Is there any order & do I have to release any button at any point to get where I have to be?

One last Q: I looked on pg for your rom, & need clarification - which mode do I have to choose in twrp to install your rom?

TIA, oldwolf

p.s. once installed, I will add BB to my forum sig!

good decision

good question about the twrp app, honestly I've never used it, I'm old school so I always manually flash via fastboot...I'll have to give it a try so I know.

new firmware usually does has fixes & improvements but HTC is not the greatest at sharing what has been improved...I always store my backups to ext sd, but no, updated firmware will not affect your backups.

yes you would flash twrp via download mode....when phone is powered off, hold power + volume down, once you feel the vibration or screen come on, let go of both....once on my ROM, I have a option on the reboot menu to reboot to download mode.

when flashing the ROM, from twrp main menu, choose install, then find the rom zip

The twrp app worked like a charm...

OMJ, Great news abt the TWRP app, thanks for trying it out & sharing. Will let you know how well everything went.

 

[oldwolf613]

OMJ, can't try your ROM yet. Flashing the FW zip you showed above finished, but didn't bring fone to 1.28… 1st time twrp & Magisk root were killed; but wasn't upgraded to 1.28... that was w/buttons->Download. Tried again on Win10 laptop w/'adb reboot downdoad', but didn't try to re-root. Same result, no 1.28… Then I reflashed twrp successfully, & I tried again (adb) - no joy. Odd thing, the Download screen showed two iterations of 2PZCIMG.ZIP in yellow (color was expected) @ the bottom of the screen, even tho my SDcard root had only 1 copy of the file & the processing of the zip took place in two stages, scrn went dark between 1st & 2nd- but I got the expected msg at the end. BTW, I tried OTA, between 2d & 3d flash failure, it got thru to the reboot, & I missed something on the screen & that too failed.

Back to flashing: iCould it be I missed something abt what is supposed to happen after you get the msg to press power btn? Would you please elaborate on that? Everything else seems to be working fine & I have nand bu of relatively new, pre- rooting & another bu w/a much more recent image. Just had probs w/restoring nands, got msg abt SD card; but I'm sure it'll all get worked out.
TIA, oldwolf

time for another lesson....flashing firmware only does not update the OS....when you update via official ota, both firmware & OS are updated...but if you only flash updated firmware, you need to flash a updated ROM to match

 

[oldwolf613]

OMJ, ohhh thanks! Was losing root upon flashing FW to be expected like losing TWRP Recovery? BTW, maybe such comments abt flashing a matching updated ROM w/the updated FW should be included w/the FW update install text, so I wouldn't have to bother you w/these issues.

Also, short of trying to flash a matching updated ROM (which I presume will then show the new version numbers) how do you know if flashing the FW was successful?

What if there is a problem w/the FW installation, what happens when you a flash matching updated ROM?

Also, when you said "if you only flash an updated FW, you need to flash an updated ROM to match“
I'm guessing that since my fone is working, the need to flash an updated rom to match is to have the new version #, i.e. 1.28… , show up in Settings->About 7.1.1

… also, in the Settings-> System update section- what is UICC lock? Thanks for all your help.

Again root has nothing to do with firmware as Root is software. Like OMJ said flashing the firmware will replace Recovery.img for S-on users. Like you did easy fix is reflash TWRP whether fastboot, sdcard or the Official TWRP app. While flashing Firmware with any method, on the screen will show progress and failed or successful install. That's how you know if it installed correctly. Even though your phone might be working with new firmware and old software, the new software will contain patches, fixes, features and security updates. The reason to update the firmware along with software is to have them work together perfectly.
UICC lock is for Sprint sim card. Basically unlocking it for another carrier, but it is not that simple I believe.

Also you being somewhat new, asking these questions is the best thing you can do. You will see many people brick(phone useless, will not turn on or keeps bootlooping) simply because they didn't ask questions until it was too late. Keeping as much as you and you will start understanding.
OTA= Firmware and software update
signed firmware= for S-on users, usually all the firmware.zip removed from the OTA for those who can't take the OTA.
modified firmware= s-off users with usually with stock recovery removed(for convenience)
ROM= the software or operating System.

just to add a little more that what schmeggy929 said...

when u flash magisk or supersu, the install process modifies the boot.img, when u flash firmware that writes a new boot.img, you wont have root until you flash magisk or supersu again

disclaimers...never been a fan, I do not add a disclaimer on my ROM thread, it means nothing...anyone that wants to root/hack/modify their phone has the responsibility to do their research prior to doing so...learning that you need to update firmware along w/ software is part of the research process

as schmeggy929 said, when flashing firmware, always pay attention to what it's doing & if there are any errors, some firmware need to be flashed 2x but it states so after the 1st flash...once firmware is flashed, you can verify the firmware level in download mode.

 

[oldwolf613]

Thanks again to both Schmeggy & OMJ,

I am trying to do my diligence, help on these forums makes a big difference. My request for comments in the ROM install thread was not my own idea. I saw that on other ROM install threads in the past. It saved everyone time: the users get better educated & the Dev didn't get as many questions bc problems were avoided. Now w/help in this thread I will likely always remember that boot.img is affected by flashing root & firmware. Rest assured, just as I did when I was into Moto modifying - I got advice fm xda folks & then when I was familiar w/the ins & outs, I helped others. And....

I have another problem. Since having flashing the FW, & twrp replaced by the native recovery, I am not able flash TWRP again. I keep getting the following error msg:


C:\Users\a\Desktop\Minimal ADB and Fastboot>fastboot flash twrp.img
unknown partition 'twrp.img' error: cannot determine image filename for 'twrp.img'

After losing twrp due to flashing the FW, the tarp.img file didn't work - so I downloaded fresh copy of the 3.1.1.0 htc u11 twrp file & renamed it to twrp.img thinking it was just corrupt. No joy. I have it stored in the same directory as immediately above; from where I am running the adb stuff.

My workflow was as following: connected fone w/orig htc data cable, checked connection via running 'adb devices', then ran 'adb reboot download', which started properly. Ran 'fastboot devices' & got expected confirmation. Then I did 'fastboot flash twrp.img' the error msg above was the result.

Please advise. TIA, oldwolf

unknown partition 'twrp.img' error: cannot determine image filename for 'twrp.img'

After losing twrp due to flashing the FW, the tarp.img file didn't work - so I downloaded fresh copy of the 3.1.1.0 htc u11 twrp file & renamed it to twrp.img thinking it was just corrupt. No joy. I have it stored in the same directory as immediately above; from where I am running the adb stuff.

My workflow was as following: connected fone w/orig htc data cable, checked connection via running 'adb devices', then ran 'adb reboot download', which started properly. Ran 'fastboot devices' & got expected confirmation. Then I did 'fastboot flash twrp.img' the error msg above was the result.

Please advise. TIA, oldwolf

I've been here at XDA for over 10yrs, one thing I've learn, most most don't read the OP, they just jump in with questions....I constantly have to repeat myself, so why waste my time in the OP....I just wait for the questions now


here is the correct cmd...


fastboot flash recovery twrp.img

OMJ, well, I'm not close to being a dev, so I won't comment further abt what to put into OP, based on your reply; I'd just wish there was a book w/all this stuff, or maybe I'll get pointed somewhere. I can give user viewpoint, & but I'm not a typical user. I used to teach in Novell's official edu-channel as a Certfd Netware Instructor, so I try to remember the 'good workflow habits' I preached in the Service & Support class.

But thanks for your help, the corrected command did it, but when notified of success & told to hit power to continue, nothing happened, so I used download mode to go into bootload mode & then rebooted system (saw on Root Junky's U tube vid) & now I have TWRP! THANKS SO MUCH!!!

Apparently, my copy of the BB2.0 has bad signature or something- so I'll have to re-D/L it & flash again.

Once I've taken care of that & 'kicked the tires' I'll get back to you & let you know how much I like it.

Thanks again, oldwolf

OMJ I got it working- but had to turn off zip signature verification. In fact, this is the case of all zip installs. I suspect that it is related to the fact that on install flash the scrn says data was decrypted w/the default password, & the verification signature failed (md5). This is even the case when I used the rom's tweaks to flip the order of the sdcard's name.

The vid that Root Junky made for the flashing twrp for the htc 10 showed to cancel using a password & to leave the (data or card) unencrypted. I never got that screen.

I was following the instructions on the u11 twrp thread- Start: as you corrected my syntax- fastboot flash recovery twrp.img & Finish: fastboot reboot.

Even the modules fm the rom's tweaks failed in the same manner until I unchecked the box for verifying the zip.

I trust your code, (constantly updating right after htc sends slw updates is gonna keep your coding fresh) but who knows what'll be if I flash other packages?

BTW, the tweak to long-press the Recent Apps button & assign Menu is a real big boon. It allowed me to use my fave & unfortunately outdated & no-longer-developed app- Loot … no menu button cut it off at the knees. It was well planned out, & a feature set that was just right, & I couldn't find a good replacement. Now that I have a Menu button; I was able to pull Loot out of the cobwebs… thanks! All the best, oldwolf
