First off,i would like to apologize for being such an amateur.This is my first post on this forum,so don't get angry on me for breaking some rules (forgive me im new ,idk if i should post this here or somewhere else,don't worry i will be polite ).Anyway as the title says,im having a bit of a problem,or to be more precise a huge one.
So lately i was trying to root my phone,Huawei U8500 which was so buggy,so i decided to root it,install cwm and flash a new ROM.But the problem is i can't get it rooted.I've tried many methods from XDA but none of them worked.Z4 root loads until it displayed acquiring root access,and then the app crashes (closes itself).I've tried Framaroot,but it didn't work either.It said 'try another exploit',but the thing is it displayed me only one.I also tried poot.apk,but it also failed.Telling me '(-) can't get a handle on it:-1 Permission denied'.
(note that all the time my USB Debugging was enabled ! ) All of the apps are at latest version!
So after so many failed attempts with pc-less methods i've decided to try a PC one.The first method i used was Superoneclick,which didn't work.I thought that was because the phones model was not supported.All until a friend of mine told me that he rooted his phone using the same program (he has as well huawei u8500).Every time i try to root with superoneclick it is stuck at the second step(as in screenshot).Then i started googleing and google-ing,until i found a thread with a program called SRSroot,thinking it will safe me from this nightmare that is haunting me for days.But it failed again.The program told me 'ADB Device not found',which made me think about checking the drivers.I've installed the google usb drivers and SDK Manager with all drivers.But still the same happens.So i decided to see if my computer(later many others) recognize my device.After i typed in ADB 'adb devices' it showed me blank.Later i tried to do the same with my other phone and it displayed the device.Another thing i've noticed lately is my computer sees my device as a cd device in windows device manager.It happened with all computers i tried. I've tried it also at my friends(plural,which means more computers).I've tried it on Win7,win XP,and WIN8 and it is still displayed as cd drive.(which is not the case with other phones i've tested!)
I hope someone will read this and help me.I would also like to add, this is not my first time rooting,so i knew what i was doing.
Im so confused,idk what to do,developers pls HELP ME!!!
I will also post screenshots from all the things mentioned above.Hope this helps you figure out the problem
On the adb devices, are you sure it is setup correct, because it needs a set of rules basically. I don't have time right now. But if you search 'adb' in the xda portal (not forum) you will find a windows universal adb installer. That should fix the adb issue. But apart from that I don't know what else you can do.

Gosh that is so confusing. Could you reset your phone or do you have data you want to keep? Because you could perform an ADB backup and try a factory reset and hope that all is righted.
I did factory reset,i also did hard reset,but still nothing works

Short of a new phone, I got nothing. Unless you could get into a recovery, try format the system, causing a brick, flash a 2.3 ftf and then a 4.04 after that, clearing data each time.

another problem with thunderbolt tool
I'm working on a buddies Thunderbolt, and ran into trouble
Ok I downloaded tool,
extracted it,
ran driver,
ran bat,
then all seemed good untill it hung at waiting for fastboot the second time where moar is mispelled. phone is on the fastboot page
when you rerun it it shows revolutionary, and s off, but if you try to flash cwm it gets to waiting on fastboot and hangs up.
installed superuser from market
try to install busybox and get an error su not found in either of two locations.
installed rom manager from market, but nothing works because cw recovery apparently not installed.
anytime you boot into recovery get a ted triangle with exclamation point.
any good ideas??
refresh my memory of adb process, its been long time since I used it
will factory reset work or will it brick the phone because of the recovery issue??
I realize this is prolly a simple issue to put a missing file into the correct location manually, or with adb, but we have gone above my unassisted pay grade.
any help is appreciated.
Thanks,
Dan

Did you ever get help with this? My phone is doing the same thing. Starts ADB and then displays the "Waiting for device connection"
message.
Anybody have an idea what I'm doing wrong?
Phone has usb debugging on and Stay Awake is on.
When it connects, my PC tells me it sees the usb device, etc. but something is still amiss....
TIA
Did you install the fastboot drivers? Also try running adb devices to make sure it recognizes its connected. I didn't get the luxury of the all in one tool when I rooted so I ended up have to root by inputting all the lines in manually to make the revolutionary tool work. It was good practice with adb though.

My buddy has a Thunderbolt that froze and so he tried flashing another rom but came across a huge issue. He tried wiping data, cache, dalvik-cache, and system (I think this is where he messed up) and when he tried flashing the new rom, it kept aborting installation. After that his recovery kept showing a log error where it couldn't mount recovery logs and also it wouldn't mount system or cache. The recovery seemed damaged at that point, so he went into HBOOT and tried flashing some stock rom through it, I guess it didn't go well because it gave an error and said something about the installed version being lower, not really sure. Now it won't even boot into recovery. Oh and here's the worst part, S-ON.. he doesn't know how to mess around with Androids, he asked if I could fix it for him. Any help would be appreciated, I know the phone was a gift for his fiance and I feel bad, I wanna help before they send it back to HTC.

Gentlemen, hello.
Ok, I have a droid razr m and I have tried BOTH the batman prog as well as the one where you use the adb shell so i can unroot. (Which doesn't happen obviously.)
On the batman prog when i press option 1 everything says failed. (Even though it resets the phone, the root is still there, remote failure ) And when i tried the abd shell, it says su file & the like isn't there. (file not found) & yes it's in the c:\ folder. (Which i dont think really makes a difference. shrugs~
Yes, i have usb options set correctly, and the allowance for non registered progs. etc etc in settings and yes im in ap fastboot. (whatever u call that black screen with white letters.)
HELP!!!
Thx in advance.
i even tried rerooting my phone just in case there was a problem with the file structure.
I also noticed (if it helps) that even when i do a factory reset (using stock image or 1.8 utility) that it still manages to connect to my router and remembers the ssid & password! which means this isn't a true image restore. (at least from a pc perspective.)
hello?
thanks for nothing.
Wat was the method u ve used for rooting... have u installed any custom recovery?

You're assuming that people know the answer to your question, and don't want to reply you. And you waited less than a DAY before saying that.
What do you want? People who have no idea about your problem to comment here and say "Sorry dude. Can't help you."?
And if you'd actually bothered to read around, you'd probably figure out that you can just fastboot another version over to unroot.
I can't for the life of me get adb to recognize my max. It's Verizon, H-boot 2.46. Trying to root and unlock. I've tried everything here....nothing. A little help please.
Only thing I can suggest, because it's happened to me, is to make sure you have the correct, most current device drivers loaded on your PC.

Are you unlocked, s-off, and rooted? Do you have developer options activated on your phone? Please explain what you´ve done up till now.

you may also need to unlocked dev tools in your settings... have you done that yet

This: http://forum.xda-developers.com/showthread.php?p=49045175
Don't know if you guys ever got this issue solved or not. I'm having the same issue S-on, cannot get adb devices command to recognize my t6spr for the life of me. on Hboot 2.46, it will detect the USB device malfunction if I put the device in fastboot mode, but thats about it. Device manager shows Unknown USB (Device Descriptor Request Failed). Tried the KB update for devices that fail enumeration on Windows 8.1 for x64 but the update package said my system is not affected so that never installed. Tried the alternative miniadb pakage previously mentioned but didnt seem to have an affect installing fastboot, adb, and drivers, across the system universally. Just not having any luck apparently. I guess I could just sell the phone Tampered and Unlocked haha with no fingerprint scanner functionality, flash ViperRom or some other stock look alike ROM. Was just really hoping to go back completely stock. At one point it time I was trying different PCs to see if it was just a system issue for me. Occasionally it seemed like if I let it sit in Fastboot AC it would eventually get detected and flip over to Fastboot USB long enough for me to push a couple commands to the phone. I have the right RUU but it dosent do me any good if the computer cant see the phone haha. Now no computer seems to recognize it. It all seemed to happen after I tried to S-Off the device with Firewater's method. Idk if I bricked something because it never worked or changed a CID or some other ID to where the USB isnt recognizable, but all I can get this phone to do is take an electric current from the USB, lol thats about it. I thought I had it fixed enough to where I knew what to do if i absolutely needed to get fastboot to recognize the phone but now, nothing.
Just a curiousity question here....a bad usb cable can produce this also...read through posts didnt see anyone trying a new cable...
Title explains it all, although the way I bricked it is honestly the dumbest way to brick a phone. Once upon a time, when cleaning this phone to be ready to sell, I was wiping it to clean it. I wanted to make sure it was all clean for the buyer, so I wiped USB-OTG I believe it's called (literally all storage). I immediately realized what a mistake I had made when I had no ROM, no backups, nothing at all. What is my best bet to go about fixing this now? I can reboot to bootloader and enter fastboot, but it seems like something integral is missing, because my computer no longer recognizes my DNA as a device. I still have TWRP 2.8.0.2 on my device, but I can do nothing with it because I have nothing to flash. I know there is an ADB sideload feature, but I cannot figure that one out either. Someone please help me unbrick this phone :crying:

Kinda doubtful. I do see a usb communication issue though. You say you've tried this on several computers, and I'm assuming they weren't all yours, which leads me to believe that you have been missing drivers. From what you've described I highly doubt the connection issue is stemming from something you deleted off the phone. The DNA is almost impossible to brick to the point of not being able to get it back.
Go here and get HTC Sync. This will ensure that you have all the updated drivers including the proper fastboot drivers. Install the program, and then reboot after installation completes.
http://www.htc.com/us/support/software/htc-sync-manager.aspx
From here you'll want to go in and uninstall it. This will remove the program, which has been known to cause usb connection/communication issues with rooting procedures, but it will leave the drivers behind. Once that completes, restart again. This should fix your fastboot problem. I've had the same problem after reformatting computers and then trying to simply download a driver pack rather than htc sync.
Also be sure to try different usb ports. Sometimes the ones in the front or side will cause problems, but the ones in the back or on the other side work just fine.
If all else fails, mail it to me and i'll fix it for you :good:
Bricked phone, no usb
My dna droid stopped working, loaded htc sync and revoot but still not seen by explorer or adb. Suggestions appreciated.
I'm stuck on waiting for all devices in adb.. My phone screen has a menu with three choices, one of them is flash unlock.bin. Should I keep waiting for all devices for how long in adb?
What procedure are you using to unlock? The WTF process is the one that I believe has worked the best for most people... and that doesn't have anything special on the phone screen, so I'm thinking you're using some app or script?

Yea, I'm following that one. I read somewhere about AMD PCs causing problems. My phone shows when I use adb devices. So should I be a little more patient or what?
No, the processes are quick. AMD Ryzens typically have issues, but it's only because of the USB driver they use. I've heard a few Intels have issues sometimes as well.
The key is, you just need to try other computers... this is the "hardest" thing to do, but it's really the only solution to that issue. The process takes under a second, so it's not a patience issue.
For the record, my older laptop with an AMD A9 CPU did the process fine... so, again, it's not a CPU issue, but a driver issue for the USB, apparently...

Some people had to use 2 or 3 computers. An older one with Intel CPU works best (especially if it has USB 2.0), but yes an AMD can work. As noted by @schwinn8 Ryzens are no go. One guy was upset because he had superfast gaming computer and we kept telling him to try another computer. He borrowed his brother's mediocre laptop and BOOM, worked. Another guy dug some old laptop out of his closet and it worked.

Also, try the steps mentioned in Wtf troubleshooting section.
Other than that you may have to mess around in the device manager section to see if the phone is detected properly or not.
(if there's a problem with the driver the device will show up as unknown android device or something)

You said "patient"... just to reiterate, this process doesn't take longer on a computer that says "waiting for device". It's a fast process, so if it's not happening within a few seconds, it won't work on that setup, period. Don't waste your time waiting - get another machine/cable/etc (check the troubleshooting steps to find other possible issues... the computer is usually the biggest problem to overcome, but the most successful).
Good news, i unlocked my phone and installed twrp, then i had to stop the process (wtf)
i still need to make a backup in TWRP and flash two more files from wtf notes. I cannot seem to be able to reboot into TWRP from ADB. thanks in advance
The oem is greyed out in developer mode and says its unlocked. Idk?
Glad to hear you got it unlocked.
In the WTF post it says that the developer mode may remain grayed out after being flipped... this is normal. It comes back after some time. Of course, you don't want to toggle it again anyway, since you're unlocked...

Bootloader unlocked is not rooted. It's just the prerequisite to being rooted. Then you install TWRP custom recovery and then use that to flash Magisk. It's all in the WTF Instructions. Also be sure to use the version of Magisk in the WTF Instructions, at least initially.
Thanks..ive got magisk from the instructions. It wants to update..should?
Once you are booted into Android, you can update Magisk to some degree. I forget the last version I had but I recall I could go to 20.x or something without issue. But there is always a risk of having issues if you update to the latest version... so be prepared to go back to the one on the WTF thread if the phone has issues. In other words, don't do this last minute or without a PC to work from... because it could fail.
The only time you have to use the old Magisk is during that first boot with it... once you're booted through, you have been able to update to newer versions. But unless you need some specific feature of the newest version, I might suggest leaving it alone...
I read somewhere..when i upgrade on US 998 20b, i need to move up to 20c?
Also, do i use the "twrp version. 20c"?
