That's a Windows Phone with Sense UI, not an Android.

What did you do to the phone?

Hi! So my phone decided to do the looping thing today and it is really stressing me out because I NEED my phone to do my job. I've tried all these things and none of them have worked. It just starts the loop all over again. I really don't want to erase my contacts, but if it happens then it happens I guess. My fault for not backing them up. Anyways. I have some questions. What is fastboot? And what is clear storage? And what is Simlock? My phone doesn't have the stock recovery so nothing but errors come up when I try the UP+POWER at the red triangle. However every now and then it says "Reboot system now" (which doesn't work), "Apply update from sdcard" (haven't tried it), "wipe data/factory reset (will this reset my contacts? I can live w/o my apps, but my contacts? :/) and "Wipe cache partition". What do these mean and which would you suggest. Your help is GREATLY appreciated!!!!!

If you saved your contacts under "Google", they can be erased and restored when you log back into your Google account. If you saved them under "Phone", say goodbye to your contacts.

Fastboot is a method of sending kernels, recoveries, and other data to your phone via your PC and the USB cord.

Clear storage will clear your...microSD card, if I remember correctly.

Simlock is a way to lock your phone's service when you boot up, I think. Never messed with it on my Vivid, because I need my SIM card.

Every HTC phone has a stock recovery, you just aren't doing the commands right. Press and hold down Volume Up AND THEN, press the Power button.

Reboot system now might say it failed, but it will reboot the phone if you're patient. It should say something like: "reason OEM-00".

Apply update from SD card is what it says: if you have an update for that phone, it would be called update.zip and it would be on your SD card. It will only work with the official Update.zip for that phone, so any custom ROM or scripts will more than likely not work.

Wipe Data/Factory Reset is exactly what it sounds like: It returns your phone back to the out-of-the-box moment. Everything is set back to stock, all apps and any other personal information is gone. Won't wipe your microSD card though.

Wipe cache partition. That means it will...how do I say this...I can't remember if it will wipe the Dalvik-cache or just the cache, but it reverts your settings back to stock on the phone.

One more tip: Turn on your phone. When you see "HTC EVO 4G", hold down the Volume Down button until your phone vibrates twice, it will vibrate a short one, and then a long one. After that, let go of the Volume Down button. See if you can boot up. If you can, you need to uninstall a bad app.

The clear storage wipes the internal storage on the phone, As long as you dont Wipe Data/Factory Reset you wont lose anything.
 
Just try the "Volume Up + Power" combination IN THAT ORDER and see if you get the stock recovery.

This really worked! i was stuck on the reboot screen ALL MORNING. technical support cldnt even help after the factory reset..wen i did the recovery, i hit volume up+power and wiped out all cache and data and reboot the fone! It finally came on after hours of failing me!

On that screen where you see the 3 Androids skateboarding, that is called the HBOOT. At the top of the screen, there is some numbers and words, I need you to tell me those. Something like...

***LOCKED (OOW) ***
HBOOT 2.xx.xx.xxxx

You get the idea. I need that info and I should be able to help you find the RUU you need.

I Tried This With My Phone And It Loops Into The Red Error Symbol .. I Pull Out The Battery And Reinster It And The Phone Reloops Into The Same Red Triangle ??? Im Stuck i Need Help And my Phone Back !!
 
I Am Still Stuck On The Loop ... i Know This Phone Is Old. It Was Working Fine In The Morning Untill i Tried To LAunch An App And It Turned Off And Started looping. I AHve Tried Several Of The Suggestions Above And None Have Worked So Far And I Cannot Find The Factory Reset Option Since I Do Not Mind All My Info. Erased i Just Want My Phone Back And Working Properly. Can Anyone Help Me !!!
 
Yeah, when you get to the red triangle, hold the Volume Up button and then press and hold the Power button until the stock recovery appears.

Or, another option: Turn on your phone normally. When you see "HTC EVO 4G" appear, press and hold down the Volume Down button until the phone vibrates twice. You'll be in Safe Mode, and from there, you can uninstall that bad app.

HTC EVO 4G - BOOT LOOP

Upon battery approaching 0%, while on a phone call, phone shut down. Immediately inserted charger and tried to start phone.
Phone went into a boot loop and is stuck unless battery is removed.

I am thinking that a ROM Update might do the trick, but I am fuzzy in some areas:
1.) Is a ROM Update Non-Volatile? In other words, will my data both on the SD-Card and on the ROM, remain intact?
2.) Can I do the update without rooting the phone?
3.) Can I do the ROM update using the Update.zip method from the SD-Card?
4.) What are the various PC36 DIAG & IMG files, and how do they play into not being able to turn on the phone
5.) What about the message below, regarding: E:Can't open /cache/recovery/command ?
6.) Do I need to use an RUU?
7.) And most importantly, where do I get the most recent update (5.07.651.1 710RD) for my phone, which I suspect is Gingerbread 2.3.3 to copy onto the sd-card?

Model# PC36100

on the Inside of the phone, on Red Tape - SC-01 - 10/07/2012

UNROOTED, AND NEVER ROOTED


Booted into Android System Recovery (ASR) HBOOT
Ran FastBoot
Went into Recovery Mode
Green Arrows stay on screen.

Upon pressing [Volume Up] and then [Power] , I get:

E:Can't open /cache/recovery/command

ROM Details

Brief answers to your questions:

1) A ROM update should not affect your data but you should perform a nandroid backup in case it is needed to restore your phone later.
2) You do need to root and unlock the EVO bootloader before you can flash a new ROM. http://forums.androidcentral.com/ht...26-guide-rooting-phone-hboot-2-18-0001-a.html
3) Yes, you will use a custom recovery to flash the ROM from a zip file containing the new ROM contents.
4) PC36IMG.ZIP is a special file that installs a custom recovery on the EVO. I recommend Smelkusmod recovery [RECOVERY][MOD][1-June-2012] RA-supersonic-v4.3-smelkusMOD - xda-developers Simply copy the downloaded PC36IMG_ra-supersonic-4.3-smelkus-mason.zip to the root folder of the EVO's sdcard and rename it PC36IMG.ZIP, then hold both the volume down and power buttons down to reboot your phone into recovery, and confirm the installation of Smelkusmod recovery when your phone detects the new recovery on the sdcard.
5) We are updating your system recovery. You can ignore the old error message.
6) An RUU is never used except to return your phone to a completely unrooted and never been rooted state in order to return or sell your phone.
7) The most recent unrooted Sprint ROM is available at [ROM][BASE] 5.07.651.6 Stock - Rooted - Latest Supersonic OTA - xda-developers. Copy the downloaded file OTA_Supersonic_5.07.651.1-4.67.651.3_...zip to the sdcard and flash this or any other ROM from the zip file on the sdcard.

Read and carefully follow all directions and you will be able to flash and enjoy the ROM of your choice.
 
dubyasux:

Thanks so much for your very thorough answers. Just a few clarifications needed.

1.) I am more concerned with the data that is on the ROM, than is on the sdcard. I have texts and voicemail that I really need to recover before I do anything that might wipe out that data. That having been said, I thought a Flash was like wiping out the card and replacing it with the new data, while an update just affects the individual/specific files of the operating system. If I run an update do I change the name to update.zip or PC36IMG.zip

2.) How do I perform a nandroid backup without the phone functioning, or are you that sure that I will not lose the data?

3.) Once again, doing a root flash sounds like it will wipe out my data on the ROM. YES or No

4.) If I do the unrooted update, is it a flash or an update? Will I lose the data located on the ROM or not?
 
Follow the advice of thugdrummer in this post http://forums.androidcentral.com/htc-evo-4g/140690-my-htc-evo-4g-stuck-reboot-infinite-loop.html to see if you can get the phone to boot normally. If you have to perform a factory reset, you will lose all voice mail and text data. SMS Backup & Restore and Titanium Backup can be used to back up text messages and voice mail data but can only be used while the phone is working.

When you flash your phone, you rewrite the contents of a portion of the system read only memory (ROM) that contains the instructions to operate your phone. In order to flash your phone, you must first root the phone and install a custom recovery that is used to erase, backup, and rewrite the system ROM. The simplest way to install a custom recovery is to download a special recovery zip file, rename the file PC36IMG.zip, copy the file to the sdcard, simultaneously press and hold the volume down and power buttons to boot into recovery, and allow the phone to detect and install the new recovery. Generally, you install a custom recovery one time and use that recovery each time you flash the ROM.

As you say there is no point in performing a nandroid backup of a non working system since it would restore the system in the same state.

Flashing a new ROM does involve erasing all the data on the ROM, so you first need to back up the text and voice mail messages you need to keep. This applies to any ROM you may choose to flash -- they all overwrite the system ROM contents and you will lose data not stored on the sdcard.
 
OK I have the HTC Sensation 4G. I am having the same issues but with a twist. Yesterday my phone shut down by itself. I couldn't get it back on. I pulled the battery to try to reinstall and noticed that a couple of the four small connection prongs that go from the motherboard to the battery were kind of bent down and pushed in. I pulled them back out (gently) and after kind of very gently wiggling them a couple times got my phone to come on, but now it boots to the main screen and I can attempt to go thru motions on the phone such as internet, setting, etc but then it freezes, then resets itself and starts over again....and keeps doing this. After reading this I did a reset thru Hboot with volume-down/power, and also wiped the cache thru recovery. It's still doing the same thing. I am wondering if some of these problems are being caused by one or more of those 4 prongs coming out to the battery. I already wiped it, lost all my info (unless I managed to sync them thru google, which I think I did but can't remember where to find that info...LOL) but man I hate to pay for another HTC phone as the Sensation 4G I have is not insured and a used one in "fair" shape still runs for $200+... Any ideas here? (and no, I did not add any new apps recently. The phone is not rooted or anything)
 
since you already wiped your data you wont lose anything by this. I would use a RUU which will rewrite all the system files to factory settings as if it were brand new again
Shipped ROMs
here are the RUU's for the sensation....

Instructions here......[GUIDE]RUU related info (Extracting rom.zip, Restoring stock, going back S-ON, etc.) - xda-developers

If you get stuck let me know

Alright Benny, I see what you are saying but I suspect mine is more of a mechanical vs operating system issue. I am going to try the RUU in the morning, I'll update as I go along. Thanks!
 
Ok, so I've spent the past week trying to get this phone that I have stable and have come to the conclusion that something is wrong with it hardware wise. However, I see a bunch of people here with a potentially simple fixes. (emphasis on POTENTIALLY) But seeing as how I'm coming to the party late and I'm not sure who's got their stuff fixed and who hasn't, let me know if you're still having a problem and I'll see what I can do for you.
