use rom manager from the market. make sure to delete dalvk cash

Clear Dalvk Cache, it makes a big difference

ok
1. so first i put the rom file on my sd card
2. then i go into recovery
3. clear dalvk cache,clear battery stats,clear cache partition
4. go to install zip from sd card,chose my rom and install it
5. restart my phone
i think thats what were supposed to do.
But my phone just keeps restarting,and nothing comes on!!
p.s. my phone is s-0ff

you need to perform a full wipe before flashing a new rom
it's the "wipe data/factory reset" option within recovery. this will format the phone properly. if you don't do this bits of system and data partitions get mixed up hence it won't boot. dalvik cache and cache are just caches...wiping them rarely solves anything.
also check that your SD card meets the ROM requirements, for instance it may require that you have an ext partition, use gparted or recovery for this, but backup your sd card to PC first

Hello,
I have a S-ON phone unlocked with htcdev.
I tried two ROMS from m1ndh4x8r, with or without overclock, but it always failed like you. White screen with HTC logo and nothing starts. I am 100% sure I did everything right...
Then I tried another ROM, HenseMod5, and it worked perfectly at the first try ! I don't know what's wrong with my device (if anything). Now HenseMod6 is out, I am installing right now.
So, try this ROM (I took the stock one):

thanks alot bro.......HenseMod worked for me too!!!!!!!
although im not sure why the others dont work for me..........maybe because of some of the feature the have and HenseMod doesnt.......

Glad to know it helped you
I don't know either why the others don't work, but I haven't really tried to figure it out. HenseMod is fine and works great for me, so I don't need another one.
By the way, I upgraded from HenseMod5 to 6 and everything's fine.

[Q] Problem booting custom rom after firmware update

Hi all,
As you can see from my post count I usually manage to solve any issues I have with the search funtion but this one has got complicated
I updated the firmware on my handset to upgrade the hboot, I know have 1.36.0000.
Since this though I'm having trouble booting any ROMs. Fastboot and CWM recovery are all fine but flashing boot.img and flashing the ROM from the sdcard I can't get past the HTC screen or sometimes the ROM's boot image. I also remember to erase cache after flashing the boot.img
I have a nandroid backup of a stock ROM that I've used to get the phone working but I'd like to know what's happening! I've tried this thread on getting out of boot loops but not had any luck.
If anyone has any ideas I'd appreciate it or if you need any other info please ask
I believe the handset has supercid but I used the info cidnum: ORANG001 3.16.61.6 anyway
I'm not very experienced with this so am hopeful I've missed something simple
Thanks in advance

This may sound stupid but did you perform a full wipe before installing the rom.zip ?

Hey, thanks for the reply.
I've been over and over the process as I thought it might be something like that, but went through the instructions for each ROM step by step and wiped everything from CWM before flashing
I've done some more Googling and it looks like a lot of people have had problems with non-sense ROMs on hboot 1.36. I'm going to download a sense one and give that a try

Ah oke.....well i know this, if you want to run CM10 you need a modified boot.img ! This one

No I can't get into the phone storage to get it. Where would I get that boot.img

yes you can, go into the recovery and mount the sdcard as a mass storage device....that way its a diskdrive and you can copy out the boot.img file....what recovery do you have, type and version number ?

Thanks for all the advice and help I'll try another rom. :good:

Need a small tut ?
start in the bootloader and flash the boot.img of the rom
unhook the cable and enter recovery (to avoid error messages)
in the recovery you do :
wipe data/factory reset
wipe cache partition
advanced - wipe dalvik cache
mounts & storage - Format cache,data,system
then you mount the sdcard as a mass storage device, hook on the cable and copy the rom.zip.
UNHOOK THE CABLE BEFORE INSTALLING THE ROM !
install the rom.zip and reboot the phone.
Good luck mate.....if you need help just ask here again :good:

[Q] Another noob with a bricked HOX

At the moment it's on a bootloop with the HTC screen, although I've managed (just now) to flash CM10 which is now stuck on a loop of the CM10 Android splash screen
I'm feeling confident that this can be sorted as I can access phone through fastboot/adb and can mount the SD so all isn't lost... I'm on UK O2 HOX
Just looking for a little direction, I used to be fairly confident around the inside of my old HTC desire, but lost interest... Things are rather different with the HOX and I suspect I've maybe screwed up with some misguided bravado...
Mr Hofs has provided some excellent learning material on his responses to issues similar to mine but to no avail...
I've tried a lot of things, bootloader is unlocked, flashed boot.img and recovery.img but when I flashed x.xx.206.x - O2 UK (United Kingdom) firmware.zip with hboot 1.36 it said it failed (with no information as to why)
Just looking for pointers on where to go next!
Starting to become concerned I've made a proper mess...

Additional to this - I've been through 10-12 pages of various fixes (searched bootloop within HOX forum) that's why the above is a little vague... They've all merged into one...

1: what hboot do you have now ?
2: what recovery are you on ?
and put the phone in the recovery in the mean time. it charges the battery there

Are you flashing cm10 or cm10.1 'cause cm10 does not support hboot 1.36.

Recovery is TWRP v2.4.1
HBoot is 1.36
and I'd read that somewhere about not supporting 1.36 and I've just checked it's 10.1 I was trying to flash

Everything sounds good to me.
Try again with my instructions:
1. Flash boot
2. Full wipe
3. Flash rom
4. Flash gapps
It should boot.

Yep....and otherwise the way around ! because i helped somebody on team-V ...it didnt work the way TT described. but actually did work the other way around
in recovery a full wipe....
install the rom and gapps
adb reboot bootloader
and flash the boot.img followed by
fastboot erase cache
fastboot reboot

Right I'll try these out - If TTs method isn't successful is there anything I would need to be aware of inbetween these two methods? Or are both pretty much starting from scratch? (I hope you understand what I mean..?)

I've expanded on the above steps to ensure I'm completing them correctly
1. Extracted the boot.img from the firmware zip contained within the CM10.1 zip, then ran fastboot flash boot boot.img from cmd line - this completed and reported "OKAY"
2. Full wipe done using TWRP - system wipe - for good measure wiped everything else too (wasn't sure if system was a catch all for the others or not)
3. Rom Flashed using TWRP install cmd (I've assumed this is the correct way to do it...)
4. Flashed Gapps similarly
It's now past the HTC "quietly brilliant" splash (very very quiet just now...) and is stuck on the CyanogenMod splash just circling round and round...
Going to try the other method see if I have anymore luck!

OK... So haven't had any luck with either method...
When flashing the boot.img it's behaving differently to how it did before - it now triggers the phone to reboot whereas it never did before... Is that normal?
Is there any more information I can give you guys that might narrow down the issue?
Thanks in advance!

i would try a stanrd sense based rom ..... just to check its all fine, i have seen more people that didnt get it booted, why ? no clue....
did a proper wipe....factory reset,wipe caches, dalvik cache, data, system ?
then it should work !

Just downloading the stock rom just now, going to try from there... At this point in time I'll be happy to just have a working phone!

Success!
I tried going back to the stock rom but something mad happened with the recovery (i.e. it didn't work anymore) and was replaced with a graphic of a flat HOX with a sync symbol and then the sync symbol was replaced by a red cross...
So had a minor panic, realised that something wasn't right with TWRP, so flashed on CWM, then flashed the boot.img from the stock zip, and flashed the rom perfectly.
I'm tempting fate but I started this process wanting a new rom and I will finish it, but I'm glad my phone isn't bricked!
Thanks to you both for your input, your faith certainly encouraged me to not give in!
Keep up the awesome work!

Well you can always try again to install CM10.1.....again but now with cwm.

I went with viper - which has flashed successfully, but everytime I unlock the screen it comes up with a white HTC screen... haha time to start trawling the viper forum... or go for CM again!

Strange.....tho i have the idea you missed something in the wiping process ?

Funnily enough for a "low stress" option I wiped everything (CWM > advanced > wipe em all) then reflashed the boot.img from CM10.1, then flashed the rom and it's loading into CM10 but repeatedly flashes "unfortunately the process com.android.phone has stopped"
There is something funny going on if no custom roms are working no?

Wipe data/factory reset
Wipe cache partition
Advanced - wipe dalvik cache
Mounts & storage - format cache,data,system
That should do it.....

ohhhhh the mounts and storage one is new to me... I'll try that now with a custom...

Meh didn't work... I'm going to reflash the stock and go to bed I think!

HTC 10 - Stock ROM recovery - Soft Bricked

Hi all,
I have an HTC 10 with:
kernel: lk
product: htc_pmeuhl
version: 1.0
version-main: 1.95.401.4
version-baseband: [email protected]
version-bootloader: 1.0.0.0000
mid: 2PS620000
cid: HTC__034
S-ON
Here's my problem.
I unlocked the bootloader, flashed latest TWRP recovery, did a full back up of Stock ROM (with TWRP Backup). Then I flashed latest SuperSU (which is supposed to not mess up the HTC 10 encryption). After that I flashed Viper10 4.1.0 ROM, which I didn't like (wasn't working well on my phone), so I wanted to get back to my stock ROM.
I went to the TWRP Restore, and reflashed the Stock ROM backup I had created before. After booting the Stock ROM was being stuck on "Decrypt your device with a password" screen. Then I decided to flash Viper10 again, and this time when I did it, it boots into and android screen saying: "Decryption Unsuccessful - Reset Phone". Clicking "reset the phone" doesn't change anything. I tried flashing the Stock ROM backup again, but TWRP says: "Unable to mount storage". Therefore I'm stuck with an unlocked bootloader, TWRP Recovery, and no working ROM.
So my understanding is that there's some mess up with the device encryption. I can see three potential options of how to fix it, but I need your help, because I'm afraid I'll brick it completely.
OPTION 1:
-The easiest would be just flashing a Stock RUU.exe for my CID/MID, this way I'd go back to full stock. However I cannot find an RUU for my firmware version: 1.95.401.4. I have S-ON, so from what I understood, I cannot do a downgrade to a lower RUU Firmware.
-What happens if I upgrade my firmware by flashing RUU with a different SKU? (e.g. 1.95.401.4 -> 2.28.617.8 which is available on HTC support site)
-Is there a way to change my CID/MID, so that I could flash Stock RUU for Unlock/Developer models?
OPTION 2:
I want to try the following:
-Format Data in TWRP (in order to get encryption off)
-Now that there's no encryption I guess I won't get "Unable to mount storage" message
-Restore backup of my Stock ROM TWRP Backup
-But I'm afraid of bricking my device completely this way, also since I read it can mess up your radio.
OPTION 3:
-Get the S-OFF somehow, from bootloader? Is it even possible? The only way I saw was through SunShine app, but I need a working ROM for that.
-Then I can downgrade my Firmware, using available Stock RUU.exe for my CID/MID (e.g. 1.95.401.4 -> 1.80.401.3)?
Really hope someone can guide me through this process. Please let me know if there are any other available option in this situation, and if the Option 2 is worth trying?
Btw, I dont care about losing data on my phone, there's nothing important there.
Thank you,
Djotto.

Hope you got your stock backup on your external sdcard or somewhere backed up on your PC.
Yes, you need to format data in TWRP, to get rid of the encryption. Else the TWRP can't mount /data.
Formatting data wipes your internal sdcard...since you already messed up any data on there is lost already, since you'll never be able to decrypt it again.

Hey j,
Thanks for the advice. With the help of amazing guys at Venom Support IRC channel, and your advice, I went ahead and formatted data in TWRP, then I flashed Viper 3.5 ROM Android M (unlike Viper 4.2 ROM Android N before that), and it worked like a charm.
Btw, just for the record, I figured out that Venom 4.2 didn't work very well for me, since I have Android M firmware, now Venom 3.5 works really well, its amazing, I'm not going back to the stock HTC 10 ROM
Thank you once again!

Why did you flash such an old version TWRP? That one is from about 3 years ago, and will cause lots of problems!
Couple simple rules to live by, when modding these phones:
1) Do not wipe things in TWRP willy-nilly, without knowing what they are, or what the result will be. The option to wipe "system" is in the Advance wipe section. It's called "Advanced" for a reason. That alone would have been a warning to be careful, and not mess with things, unless you know what you are doing. It also clearly says in TWRP wipe screen, that most of the time, the default wipe (cache, Dalvik/ART and data) is all you ever need. It says that for a reason.
2) Right after you install TWRP, and before messing around with anything, you should make a TWRP backup of your current stock ROM. Definitely do that, before trying to flash root, ROMs, or any other mods. That way, if anything goes wrong (or you simply screw up, and wipe system) you have a backup, that you can easily restore.

In general, you should never flash a file named "OTA" unless you know exactly what you are doing. The requirements for an OTA on this device are steep:
a) Must currently have the version number directly before the OTA number (you can't skip or flash the same number OTA)
b) Must have stock recovery installed (not TWRP)
c) Must match your version (CID, MID). Do you have the Euro version? You never stated this info.

This RUU is only for the US Developer's Edition version M8. Will not work on any other version.
Even if you had the US Dev Ed (which is unlikely) this RUU would require the firmware being flashed, before the RUU will install (thus, Error 155).
In short, it seems like you are just guessing at solutions. Not a good idea.
