[Q] Delete personal data from non-booting phone

Hi everyone
I have a Huawei U8800 which I can no longer boot (it gets stuck at the white Huawei screen). I can, however, access the 'pink screen' (vol+, vol-, power button) and the files when connecting it to my computer, but entering recovery mode (vol+, power button) does not seem to work.
I am an utter noob, so my approach to solve my problem would be to simply take the phone back to the shop, but first I would like to erase my personal data. Is this possible in my case, without voiding my warranty? In case it is not, could you perhaps tell me how I could go about fixing the phone myself (in such a case I would also be willing to scrap the warranty)?
Thanks a lot in advance!
PS: I have not rooted the phone or done anything like that, all I did was installing a couple of apps, so it's pretty much in its original state.

You should be able to flash one of the original roms and the phone would boot if there're no hardware problems.
The original roms were removed from the huawei website but if you search the site there were plenty links afaik.

Thanks dionero. The trouble is that I am too much of a noob to understand what exactly you mean by 'flash one of the original roms'. Could you please provide some more detail? Thanks a lot

Here is a rom with instructions on how to flash :

Thanks again! I will give it a go later on today.

Did you manage to recover the phone?

Thanks for asking! First I need to go and buy a micro SD card, as that seems to be required for the process. But I'll post an update once that's done and I've attempted the recovery. Thanks again for your time!!

Hi,
finally the micro SD card has been delivered - I'll never buy from that shop again, what long shipping times!
Anyway, I'm afraid the recovery did not work. The phone did react, said it was performing the upgrade, and it the end it even displayed the "Upgrade completed" message. Attempts to reboot, however, still don't let me get any further than the Huawei screen
One further observation I have made (even before the attempted recovery, but ever since the phone stopped booting): when the phone is switched off (which nowadays can only be accomplished by removing the battery), and I plug it into the power outlet, it immediately starts its booting attempt. When the phone was still alright, however, it would recharge its battery without trying to boot immediately. I don't know whether that's important, but maybe someone can make use of this information!?
Well, in case anyone on here has got some more suggestions as to what else I could try I would be really grateful. Thanks a lot for your time and effort, and for reading this!

How long did you wait at the Huawei screen? First start takes longer time and it should reboot multiple times. Anyway, you should try flashing one of the recoveries, 5.0.2.3 for example. You can find it in the development section. With that you should wipe cache and data, delete dalvik cache and then try to start it.
I'm on mobile so I can't give you a good tutorial, but recovery should be fairly easy to install (look for stockwell's recovery).

Thanks, Blefish, for your reply. I tried recovery flashing at some point along the way, and I tried it again now, this time using the version you suggested. Still I simply cannot boot into recovery mode. I can either get the "pink screen", or simply the white Huawei screen, even if I press Vol+ and the power button (I've also tried pressing them for different amounts of time, but all to no avail)
Oh, and as an answer to your question: I waited for maybe 15 minutes or so.

Sorry wrong info

1. Download a stock rom.
2. Create a folder on the SD card named "dload"
3. Copy UPDATE.APP and UPDATE_CUST.APP from stock rom archive to dload folder
4. Insert sdcart to phone
5. Switch on phone with press vol+ and vol- buttons
6. The installation will start automatically

Thanks ufukyayla, but what you're suggesting is exactly what dionero had suggested earlier, and unfortunately it did not work.

[Q] First blue screen, now boot loop.

Hello XDA-devs forums,
I'm having an issue since yesterday.
I have rooted my Huawei Ideos X5, and it ran fine for a day or so.
However, when my battery ran out it shut down into a completely blue screen.
When I tried booting it again, this just showed me a blue screen as well.
Now, I fixed this issue by connecting the phone to my PC after booting it with the Vol+ and Vol- pressed.
(So you get the pink/purple screen)
However, when I opened the phone on my PC, all I saw was a "239 MB" "empty" space, and it should have ~2GB..
I placed a backup copy I saved of my "image" folder in that 239 MB storage, and it booted.
However, today I hooked it up to my PC again to see if it magically changed..
And I couldn't access the 239 MB space anymore.
When I tried fixing the issue with a reboot of the phone, that just caused it to get stuck in a booting loop.
So now I'm stuck with a phone that keeps trying to boot itself,
and I can't access it on my windows PC.
I can, however, access 4 different folders of the phone on my linux notebook.
Now, my question is: can someone with a good understanding of problems like these please help me out?
I'm getting kind of fed up with it, as I've only got the phone for 2 days now.
Thank you in advance, and thank you for taking the time to read this.

Have you tried removing the battery for 5 minutes and then putting it back in?
After this, what happens when you press VOL+ and Power?
How about if you press VOL+, VOL- and Power, without the USB cable?

Hello Katu, thank you for posting.
Regarding your questions:
Yes, I have tried to take out the battery for 5+ minutes- it didn't change anything to the situation unfortunately..
If I press VOL+ and Power at the same time, the device boots into recovery mode.
In this I have tried to format the device in order to reset it to factory defaults, but this did not help either.
When I press VOL+, VOL- and Power, the phone boots into the pink/purple screen.

Can you try a custom recovery and a custom rom? I want to see if your onboard flash is borked.

I had the same when my phone got f*ucked up. Put the image folder, than download official rom, like b138 and install it. then check your imei. There is a change that it will be 0.

Well, I used an original ROM:
U8800 V100R001C00B136(Overseas General version)
And that resulted in the boot.img being corrupted, so I can't even overwrite that anymore.
Also, this is what I see when I hit VOL+, VOL- and Power at the same time to boot into safe mode, and connect it to my PC.

I installed the official B136 rom, and after it rebooted, it would just hang on a black screen.
(it used to show the IDEOS or Android logo when it booted)

Hmm mine came with this Rom
U8800 V100R001C00B135SP01 ( general )
Looking at your name you're from the Netherlands ( so am I )
where did you get this 136 version from ?
I would try to put this one on it
You have to put the 'dload' folder into the root of your SD Card,
then boot into boot-loader, after that it'll automatically flash back to the stock Rom.
1 Format SD card
2 On the SD card, create "dload" folder
3 Put the unzipped Rom into "dload" folder
4 Then boot to bootloader (pink screen)

Yes, mine came with that version as well.
However, I couldn't find it anymore and thus downloaded the version I said earlier.
Also, I did everything as you described, except step 4.
You have to boot to recovery instead of bootloader. (VOL+ and Power)
Anyways, I managed to get ClockworkMod's recovery.img on my phone,
and from there on install a custom ROM on the phone, which magically got it working again - even though it didn't work earlier.
Thank you for reading my thread and taking the time to reply to it.
My issue has been resolved.

just for the record, flashing a stock rom is different from flashing a custom rom..
the 4 steps described by Gman2oo6 is the correct way to flash a stock rom (and it is written clearly in the document that is in the stock rom zip file)
[edit]
step (1) is not a necessary step though..

Yeah, I noticed that.
What I did was format my SDcard with FAT32,
and put a custom rom (update.zip) on the SDcard.
I then booted ClockworksMod Recovery and installed the custom rom from the SDcard.
When I tried installing the stock rom, I just followed the PDF file's instructions that came with the stock rom.

hey i udated to GB 2.3.4 (official)and i didnt like the it cuz the wifif ddnt work and the bluetooth also the DATA so itryed to downgrade to 2.2.2 original official and it did the 2/2 steps intalled and when it restarted it did not want to turn on all that happened was it vibrated and thats all so i left it on like that and when the battery died i plugged it in to the AC and the LED turned on red and the touch kkeys also but not the screen so i really NEED help!

Try to turn it on with lead connected but no battery and see if you can start it.
My battery also went dead flat this morning and I couldn't get it started at all till I tried this. Once I got it started the only thing I could do was quickly pop in the batery and let it charge. Just leave off the cover till you get it going.
I have to add that I did not have the problem of a failed update to deal with but it may at least get you started

i tryed it
nope nothin good happened all that happens is a blank screen with nothin on ,LED is off and the touch keys are off. it justz vibrates and when i put the battery it turn the LED on to red and the touch keys turn on but then like 5 min later the LED and keys turn off

ok heres what i did i wanted to upgrade my phone to the newest version GB 2.3.4.So what i did was download the update and i followed the installation steps i successfully updated to Gb 2.3.4. so like i was checking how it look and the new feature but when i wanted to go on the android market i went to setting and turn on the wifi and it said Error and then i tried the Bluetooth and it said Error also so then i put my SIMs card in and i was like imma use DATA then and when i restarted my phone it had service but no HSPA+ or Edge or GPRS so like i just hatted my phone from their so then i was trying to root it but iddnt know how to do that so like i read this website and i got the UPDATE.APP or 2.2.2 AT&T did the same steps of the installation of BG 2.3.4 and it went to the process and 1/2 stepp good it passed and then 2/2 also passed it installed it and when it said Successively Installed it said Restarting and the scrren turn of and it vibrated and thats all that happened and i left it like that for the whole days and nothing happened
Do u got any idea?
When i connect it to my laptop it says installing drivers .then its says sucesfully installed drivers ready to use. so then i got to Device Manger and i check what has been installed and their it said USB Human interface device and HID-compliant device WHAT DOES THAT MEAN??

Not sure about the HID (human interface device) probably just the way windows sees the device for interfacing with it. With regards to the not booting I have read a lot of people saying that you need to factory reset and clear cache after the upgrade/downgrade. With the phone off, turn it on by long pressing volume+ and power on button till you get the blue recovery screen and from there you can reset factory/ data and also clear the cache. from what I see this should clear up the problem and start up. Please read this thread, it may help you somehow..... http://forum.xda-developers.com/showthread.php?t=1420728
Hope this helps a little

I can get into the pink screen bu pressing Vol up + Vol Down + power.
I can also get to the blue screen Vol Up + Power.
i cannot change any thing in any of the drives or partitions in the pink screen. the image folder (in the pink screen), and other partitions also all the 4 partitions are freezed. even if i delete or replace files, the previous files comes back the very next movement. as if the memory is freezed. i even tried to format the 253 MB partition (image folder partition) but format gives error cannot format this drive , checked the attributes is unchangeable read only partition.
i tried updating official rom 2.2.1, 2.2.2, 2.3.5, but update failed, Some times even it reaches the update process to STEP 2/2 and there its like hanged the progress doesn't moves further even tried keeping hours, also tried update without battery but the same.

Any ways i will try again without holding power ...........
my problem is my phone doesnt get updated with any rom even the stock 2.2.1. and just keep it into boot loop at android animated logo screen.
Well Maksimitoisto, i cannot claim on my warranty as it is already out and sencondly befor i can put efforts and take pain of paying for another phone or replacement, i want to try max what we can do on it to solve the issue.
since the phone can boot into the Pink and blue screen and also the normal way (with boot loop) i belive its not more then a software problem, the only thing is i need to get the right to overwrite it.
Any help please write.
Appreciate everyonce solutions & support.

[Q] Huawei Y625, softbricked, tried everything, no solution

Please help me. I have a Huawei Y625 (a bit more than a year old), it is NOT rooted. I have never attempted to customize it/tinker around with it. I don't even know the exact terminology so I'm sorry if I get something wrong.
Yesterday it suddenly went into a bootloop, it kept saying "DataBackupStart" with a bunch of processes failing.
I held volume down + power button, which opened a menu entirely in Chinese.
I clicked everything on that menu, but those were just some tests, like camera and sound test.
Then I powered it off, held volume down+volume up+power button this time, and it finally got me to recovery mode I think.
I wiped cache, and I wiped all data, which did a factory reset. It was OK with me because I just want it to work.
Then I tried to reboot it, but then it started behaving even worse. It will not turn on until I remove and put back the battery, and then it will vibrate, show the Huawei logo for a few seconds and then turn off again. It never got past that logo, except if I turn on recovery mode.
I found its official stock files, put the 'update.app' in the dload folder on sdcard, then tried to activate that rom in the recovery mode. It says 'error, status 7, installation aborted'. I googled it but I do not understand a thing, I really don't get these tutorials and I don't know what to do about that.
I tried downloading Marshmallow 6.0 version, because I thought maybe upgrading Android would help, but I cannot find any download links that work.
I am out of my mind, I need my phone and nothing I found on the Internet has been helpful. I don't even know how it came to this since I have never even attempted to root my phone! Please help me, thank you. :crying::crying::crying:

Need Help with S7 Edge (SM-935FD)

Hi! It's my first time making a thread here so guidance is greatly appreciated. Here's how everything started:
I was just casually using my phone (at the time I was using the built-in browser of google assistant, just looking at some news) then suddenly my phone crashed (I've experienced this before every time I was using the google assistant built-in browser, a simple browser can crash this phone?). It just restarted like it normally would, then, after using the phone for a few minutes, it froze again! I waited for it to reboot but now it just powered off and won't turn on (it won't show any sign of life, no logo, not even an icon when I tried to charge). D:
I figured to have it checked by a local technician and when he tried to plug a charger in, a display showed it charged (found it weird but happy at that time). I figured it was the charger so I bought a new one.
So I got home to charge it fully and when I turned it on, it worked normally. However, when I tried to turn my wifi on, notifications popped up and suddenly it froze again! After that, it turned off and when I tried to turn it back on, I got this dreaded red texts on a black screen:
Bootloader exception ( RST_STAT = 0x10000)
Exception: do_handler_sync: DABT_EL1(esr: 0x9600010)
RDX, do not reboot*** ext4_wait_block_bitmap:494: Cannot read block bitpc : 0x8f0261d0 lr : 0x8f02618c sp : 0x8f117fd0
This showed and the phone won't even let me turn it off, so I just waited for the battery to die out. When it did, I tried to charge it again and planned to do a factory reset thinking maybe an app was causing this. I managed to go to the no command icon and manual mode but no factory reset menu showed up (where you navigate using the volume up and down). So I tried to restart but now it died out completely- no button combination would work, it won't charge, no display can be seen. Is it hard bricked?
I tried to wait a whole day thinking I would be able to charge it again, but it has already been three days and I am not able to perform anything.
There it is, I tried to be as detailed as possible. Additional info: I never tried rooting it or flash roms with it, I haven't done anything with the software (or hardware since I am careful) but install apps (officially from the playstore). From how I see it, it's a firmware problem and I was hoping someone here can help me bring my phone back to life. Is this my fault? If I have this repaired, am I the one who should pay for this?
I mainly want to know what the error message means and if there is a way for me to access the phone. (I figured if I have the technician fix this, all they need is a computer with a software that could fix this since it's a problem with the firmware. If that's everything they would do then I could do that too, with your help of course.)
Thanks to all in advance!

Hi. This sounds pretty strange. Technically...it is hard bricked but you can bring it to life. I can tell you what I would do, when I run into such a problem.
ATTENTION: YOU WILL LOOSE ALL OF YOUR DATA EXPECT EXTERNAL SD CARD
First download the newest firmware for your S7 Edge (G-935FD) on SamMobile and unpacking the .zip.
Download Odin in the newest version, open it and put the downloaded files in the right order in Odin (BL, AP, CP and CSC - the files from the firmware from SamMobile has labeling with BL, AP etc.)
Now the tricky part because your phone won't charge and doesn't go on. You have to go in the download mode with your phone (press and hold volume down - home button - power button) than an window appears and press volume up
Connect your phone with your PC (in Odin you can see, that your device is connected) and press start. It will take some time transferring the ROM and your phone will reboot automatically and after some minutes of blinking Samsung logo...the phone should start normally into the SIM card pattern screen.
Now you have a fresh stock ROM installed and everything should work fine again.
But your phone won't get on or will charge...maybe when you connect it to your PC it will charge. Otherwise I see no option to solve your problem. Your phone must charge again that you can go into the download mode and bring your S7 Edge back to life with a clean stock firmware and an working system.
